HIV and the Macrophage: From Cell Reservoirs to Drug Delivery to Viral Eradication
Abstract
Macrophages serve as host cells, inflammatory disease drivers and drug runners for human immunodeficiency virus infection and treatments. Low-level viral persistence continues in these cells in the absence of macrophage death. However, the cellular microenvironment changes as a consequence of viral infection with aberrant production of pro-inflammatory factors and promotion of oxidative stress. These herald viral spread from macrophages to neighboring CD4+ T cells and end organ damage. Virus replicates in tissue reservoir sites that include the nervous, pulmonary, cardiovascular, gut, and renal organs. However, each of these events are held in check by antiretroviral therapy. A hidden and often overlooked resource of the macrophage rests in its high cytoplasmic nuclear ratios that allow the cell to sense its environment and rid it of the cellular waste products and microbial pathogens it encounters. These phagocytic and intracellular killing sensing mechanisms can also be used in service as macrophages serve as cellular carriage depots for antiretroviral nanoparticles and are able to deliver medicines to infectious disease sites with improved therapeutic outcomes. These undiscovered cellular functions can lead to reductions in persistent infection and may potentially facilitate the eradication of residual virus to eliminate disease.

The impact of [ 68 Ga]PSMA I&T PET/CT on radiotherapy planning in patients with prostate cancer
Abstract
Purpose
To determine the impact of Gallium-68-labled prostate-specific membrane antigen positron-emission tomography/computed tomography ([68Ga]PSMA PET/CT) on radiotherapy planning for primary disease, biochemical cancer relapse, and advanced disease of prostate cancer.
Methods
A total of 106 patients with prostate cancer scheduled for radiation therapy underwent 120 [68Ga]PSMA PET/CT scans prior to radiotherapy treatment. In 20 cases, patients underwent [68Ga]PSMA PET/CT for primary therapy (PT), 75 cases were referred for biochemical relapse after surgery (RL), and 25 cases were intended for palliative treatment of localized metastases (MD). We retrospectively compared the impact of [68Ga]PSMA PET/CT on lesion detection and treatment decision to CT alone.
Results
[68Ga]PSMA PET/CT revealed a total of 271 positive lesions, whereas CT detected 86 lesions (32%). Overall, the radiotherapy regime was changed in 55 of 120 cases (46%) based on the higher detection rate of [68Ga]PSMA PET/CT: in 15% of cases with PT, in 43% of cases with RL, and in 44% of cases with MD.
Conclusion
[68Ga]PSMA PET/CT is superior to CT alone for lesion detection in prostate cancer, thereby significantly impacting on radiotherapy planning for primary disease, biochemical cancer relapse, and advanced disease of prostate cancer.

Standardizing procedures improves and homogenizes short-term outcomes after minimally invasive esophagectomy
Abstract
Purpose
Esophageal cancer is one of the deadliest cancers worldwide. Esophagectomy with lymphadenectomy is regarded as the only curative option for resectable esophageal cancer, but it is associated with high morbidity and mortality. Multidisciplinary team (MDT) management was recently associated with improved outcomes after surgery for esophageal cancer. The aim of this study was to investigate the effect of standardizing procedures for minimally invasive esophagectomy (MIE) in the MDT setting.
Methods
This was a case-matched control study of 154 patients with esophageal cancer who underwent thoracoscopic esophagectomy in the prone position (TEP) between 2012 and 2016. Surgery was performed by two attending surgeons (surgeons A and B) who began working together in the same MDT in 2015. At that time, the following surgical procedures were standardized between surgeons A and B: mediastinal lymphadenectomy, abdominal procedures, and estimation of the blood supply of the gastric conduit. Short-term outcomes were compared between the following paired groups using propensity scores: surgeon A's pre- and post-standardization groups, surgeon B's pre- and post-standardization groups, and surgeon A's post-standardization group and surgeon B's post-standardization group.
Results
Concerning surgeon A, the estimated total blood loss in the post-standardization group (142 ± 87 mL) was significantly lower than that in the pre-standardization group (376 ± 215 mL, P = 0.006). The rate of left recurrent laryngeal nerve palsy in the post-standardization group (13%) was significantly lower than that in the pre-standardization group (47%, P = 0.046). Concerning surgeon B, the rate of anastomotic leakage in the post-standardization group (0%) was significantly lower than that in the pre-standardization group (11%, P = 0.039). Comparing the post-standardization groups of surgeons A and B, there were no significant differences in operative outcomes or morbidity.
Conclusions
Standardizing procedures for MIE improved and homogenized surgical short-term outcomes.

A case of mature cystic teratoma with intestinal structures harboring intestinal-type low-grade mucinous neoplasm
Abstract
The formation of gastrointestinal-type epithelium is found in 7–13% of mature cystic teratomas, which are the most common germ cell tumors of the ovary. Few cases harboring organized gastrointestinal tract formation have been reported, and a mucinous neoplasm arising in them is further rare. Here, we report a case of an ovarian mature cystic teratoma with intestinal structures harboring intestinal-type mucinous neoplasm, mimicking low-grade appendiceal mucinous cystadenoma. A 66-year-old female, with remarkably increased serum carcinoembryonic antigen (CEA) level, underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy due to the ovarian tumor. The immunoprofile of the tumor showed CK7−/CK20+. We review the past literatures, and then consider that the existence of mucinous neoplasm should be kept in mind if we find elevated level of serum CEA and the organized gastrointestinal development in an ovary. The immunoprofile of CK7/CK20 is useful to determine the origin of mucinous tumors associated with mature cystic teratomas.

Noradrenergic Modulation on Dopaminergic Neurons
Abstract
It is now well accepted that there is a close relationship between noradrenergic and dopaminergic neurons in the brain, especially referring to the modulation of the locus coeruleus–norepinephrine (LC-NE) system on dopamine transmission. The disturbance of this modulation may contribute to neurodegeneration of dopaminergic neurons in Parkinson's disease. In this article, we briefly review evidence related to such modulation. Firstly, we illustrated the noradrenergic innervation and functional implication for the LC-NE system and nigra–striatum dopaminergic system. Furthermore, we depicted neuroprotective effects of the LC-NE on dopaminergic neurons in vivo and in vitro. Moreover, we present data implicating the potential mechanisms underlying the modulation of the LC-NE system on dopaminergic neurons, in particular the effects of NE as a neurotrophic factor and through its ability to stimulate the expression of other neurotrophic factors, such as the brain-derived neurotrophic factor. Finally, we discussed other mechanisms intrinsic to NE's effects. A better understanding of the noradrenergic modulation on dopaminergic neurons may be rewarding by significant advances in etiologic study and promising treatment of Parkinson's disease.

To Evaluate the Role of H. pylori in Patients with Chronic Recurrent Tonsillitis
Abstract
The usual indication for surgical resection of tonsils is chronic recurrent tonsillitis. Literature also does not indicate the reason behind the fact that only part of the population suffers from recurrent chronic tonsillitis in spite being exposed to similar conditions. This was a prospective study, in which 50 tonsil biopsy samples obtained from chronic tonsillitis patients. Specimens were analysed with rapid urease broth test, HelicotecUT PLUS assay and Toluidine blue staining for presence of Helicobacter pylori. The age ranged from 4 to 34 years. The median age for patients with chronic recurrent tonsillitis was 9.5, 23 (46%) patients were male while 27 (54%) were female, presence of H. pylori by rapid urease broth test, HelicotecUT PLUS assay and Histopathology was 4%. Our analysis revealed that H. pylori did not significantly colonize the tonsils and does not play a role in the pathogenesis or development of chronic tonsillitis. The heterogeneity in study population and methodology may have contributed to the non significant results.

Multi-locus transcranial magnetic stimulation—theory and implementation
Publication date: Available online 23 March 2018
Source:Brain Stimulation
Author(s): Lari M. Koponen, Jaakko O. Nieminen, Risto J. Ilmoniemi
BackgroundTranscranial magnetic stimulation (TMS) is a non-invasive brain stimulation method: a magnetic field pulse from a TMS coil can excite neurons in a desired location of the cortex. Conventional TMS coils cause focal stimulation underneath the coil centre; to change the location of the stimulated spot, the coil must be moved over the new target. This physical movement is inherently slow, which limits, for example, feedback-controlled stimulation.ObjectiveTo overcome the limitations of physical TMS coil movement by introducing electronic targeting.MethodsWe propose electronic stimulation targeting using a set of large overlapping coils and introduce a matrix-factorisation-based method to design such sets of coils. We built one such device and demonstrated the electronic stimulation targeting in vivo.ResultsThe demonstrated two-coil transducer allows translating the stimulated spot along a 30-mm line segment in the cortex; with five coils, a target can be selected from within a region of the cortex and stimulated in any direction. Thus, far fewer coils are required by our approach than by previously suggested ones, none of which have resulted in practical devices.ConclusionAlready with two coils, we can adjust the location of the induced electric field maximum along one dimension, which is sufficient to study, for example, the primary motor cortex.

To Evaluate the Role of H. pylori in Patients with Chronic Recurrent Tonsillitis
Abstract
The usual indication for surgical resection of tonsils is chronic recurrent tonsillitis. Literature also does not indicate the reason behind the fact that only part of the population suffers from recurrent chronic tonsillitis in spite being exposed to similar conditions. This was a prospective study, in which 50 tonsil biopsy samples obtained from chronic tonsillitis patients. Specimens were analysed with rapid urease broth test, HelicotecUT PLUS assay and Toluidine blue staining for presence of Helicobacter pylori. The age ranged from 4 to 34 years. The median age for patients with chronic recurrent tonsillitis was 9.5, 23 (46%) patients were male while 27 (54%) were female, presence of H. pylori by rapid urease broth test, HelicotecUT PLUS assay and Histopathology was 4%. Our analysis revealed that H. pylori did not significantly colonize the tonsils and does not play a role in the pathogenesis or development of chronic tonsillitis. The heterogeneity in study population and methodology may have contributed to the non significant results.

Coincidence of Concha Bullosa with Nasal Septal Deviation; Radiological Study
Abstract
Introduction Concha bullosa (CB) is the most common sinonasal anatomical variation reported in literature, it occurs most often in the middle turbinate. Causes of development are not clearly identified but coincident prevalence with deviated nasal septum (DS) is common. Objective To study the relationship between DS and development of CB. Methods A prospective study including 40 patients with DS, CT scans were thoroughly analyzed to detect the presence of CB, its type, and laterality. Effect of degree of septal deviation from the midline and level of deviation in the axial plane were also addressed. Results The study included 40 patients with DS; 15 of them had associated CB; the lamellar type of CB was the most prevalent followed by the true type. Conclusion Incidence of CB was higher in patients with increased angle of septal deviation and with lower level of deviation in the axial plane.

Depleted polymorphonuclear leukocytes in human metastatic liver reflect an altered immune microenvironment associated with recurrent metastasis
Abstract
Background
Hepatic immunity, normally protective against neoplasia, is subverted in colorectal liver metastasis (CRLM). Here, we compare the inflammatory microenvironment of CRLM-bearing liver tissue to donor liver.
Methods
Twenty-five patients undergoing resection for CRLM were recruited, 13 of whom developed intrahepatic recurrence within 18 months. Biopsies were obtained from tumour and normal liver tissue adjacent to and distal from, the tumour. Donor liver biopsies were obtained during transplantation. Biopsies were cultured and conditioned media (CM) screened for 102 inflammatory mediators. Twelve of these were validated by Luminex assay. Transwell assays measured cancer cell chemotaxis. Polymorphonuclear leukocytes (PMN) and lymphocytes were quantified in H&E sections.
Results
Fewer periportal tissue-resident PMN were present in metastatic liver compared to donor liver. Patients with the fewest PMN in liver tissue distal to their tumour had a shorter time to intrahepatic recurrence (P < 0.001). IL-6, CXCL1, CXCL5, G-CSF, GM-CSF, VEGF, LIF, and CCL3 were higher in liver-bearing CRLM compared to donor tissue. Consequently, cancer cells migrated equally towards CM of all regions of metastatic liver but not towards donor liver CM.
Conclusions
The local inflammatory environment may affect both immune cell infiltration and cancer cell migration contributing to recurrence following resection for CRLM.

Diacylglycerol kinase α inactivation is an integral component of the costimulatory pathway that amplifies TCR signals
Abstract
The arsenal of cancer therapies has evolved to target T lymphocytes and restore their capacity to destroy tumor cells. T cells rely on diacylglycerol (DAG) to carry out their functions. DAG availability and signaling are regulated by the enzymes diacylglycerol kinase (DGK) α and ζ, whose excess function drives T cells into hyporesponsive states. Targeting DGKα is a promising strategy for coping with cancer; its blockade could reinstate T-cell attack on tumors while limiting tumor growth, due to positive DGKα functions in several oncogenic pathways. Here, we made a side-by-side comparison of the effects of commercial pharmacological DGK inhibitors on T-cell responses with those promoted by DGKα and DGKζ genetic deletion or silencing. We show the specificity for DGKα of DGK inhibitors I and II and the structurally similar compound ritanserin. Inhibitor treatment promoted Ras/ERK (extracellular signal-regulated kinase) signaling and AP-1 (Activator protein-1) transcription, facilitated DGKα membrane localization, reduced the requirement for costimulation, and cooperated with enhanced activation following DGKζ silencing/deletion. DGKiII and ritanserin had similar effects on TCR proximal signaling, but ritanserin counteracted long-term T-cell activation, an effect that was potentiated in DGKα−/− cells. In contrast with enhanced activation triggered by pharmacological inhibition, DGKα silencing/genetic deletion led to impaired Lck (lymphocyte-specific protein tyrosine kinase) activation and limited costimulation responses. Our results demonstrate that pharmacological inhibition of DGKα downstream of the TCR provides a gain-of-function effect that amplifies the DAG-dependent signaling cascade, an ability that could be exploited therapeutically to reinvigorate T cells to attack tumors.

A large-scale, exome-wide association study of Han Chinese women identifies three novel loci predisposing to breast cancer
Genome-wide association studies have identified more than 90 susceptibility loci for breast cancer. However, the missing heritability is evident, and the contributions of coding variants to breast cancer susceptibility have not yet been systematically evaluated. Here we present a large-scale whole-exome association study for breast cancer consisting of 24,162 individuals (10,055 cases and 14,107 controls). In addition to replicating known susceptibility loci (e.g. ESR1, FGFR2 and TOX3), we identify two novel missense variants in C21orf58 (rs13047478, Pmeta = 4.52 × 10-8) and ZNF526 (rs3810151, Pmeta = 7.60 × 10-9) and one new non-coding variant at 7q21.11 (P < 5 × 10-8). C21orf58 and ZNF526 possessed functional roles in the control of breast cancer cell growth, and the two coding variants were found to be the eQTL for several nearby genes. rs13047478 was significantly (P < 5.00 x 10-8) associated with the expression of genes MCM3AP and YBEY in breast mammary tissues. rs3810151 was found to be significantly associated with the expression of genes PAFAH1B3 (P = 8.39 x 10-8) and CNFN (P = 3.77 x 10-4) in human blood samples. C21orf58 and ZNF526, together with these eQTL genes, were differentially expressed in breast tumors versus normal breast. Our study reveals additional loci and novel genes for genetic predisposition to breast cancer and highlights a polygenic basis of disease development.

IL-22RA1/ STAT3 signaling promotes stemness and tumorigenicity in pancreatic cancer
Chronic inflammation is a feature of pancreatic cancer, but little is known about how immune cell or immune cell-related signal affects pancreatic cancer stemness and development. Our previous work showed that IL-22/IL-22RA1 plays a vital role in acute and chronic pancreatitis progression by mediating crosstalk between immune cells and acinar cells or stellate cells, respectively. Here we find IL-22RA1 is highly but heterogeneously expressed in pancreatic cancer cells, with high expression associated with poor prognosis of pancreatic cancer patients. The IL-22RA1hi population from pancreatic tumor harbored higher stemness potential and tumorigenicity. Notably, IL-22 promoted pancreatic cancer stemness via IL-22RA1/STAT3, which identified a functional signaling to regulate cancer stemness by microenvironmental factor. Moreover, STAT3 was indispensable for the maintenance of IL-22RA1hi cells. Overall, these findings provide a therapeutic strategy for PDAC patients with high expression of IL-22RA1.

Therapeutic targeting of sunitinib-induced AR phosphorylation in renal cell carcinoma
Androgen receptor (AR) plays a crucial role in the development and progression of prostate cancer. AR expression has also been reported in other solid tumors, including renal cell carcinoma (RCC), but its biological role here remains unclear. Through integrative analysis of a reverse phase protein array (RPPA), we discovered increased expression of AR in an RCC patient-derived xenograft model of acquired resistance to the receptor tyrosine kinase inhibitor (RTKi) sunitinib. AR expression was increased in RCC cell lines with either acquired or intrinsic sunitinib resistance in vitro. An AR signaling gene array profiler indicated elevated levels of AR target genes in sunitinib-resistant cells. Sunitinib-induced AR transcriptional activity was associated with increased phosphorylation of serine 81 (pS81) on AR. Additionally, AR overexpression resulted in acquired sunitinib resistance, and the AR antagonist enzalutamide-induced AR degradation and attenuated AR downstream activity in sunitinib-resistant cells, also indicated by decreased secretion of human kallikrein 2 (KLK2). Enzalutamide-induced AR degradation was rescued by either proteasome inhibition or by knockdown of the AR ubiquitin ligase speckle-type POZ protein (SPOP). In vivo treatment with enzalutamide and sunitinib demonstrated that this combination efficiently induced tumor regression in an RCC model following acquired sunitinib resistance. Overall, our results suggest the potential role of AR as a target for therapeutic interventions, in combination with RTKi, to overcome drug resistance in RCC.

Vitamin D and primary hypothyroidism: Is there an association?
Thyroid Research and Practice 2018 15(1):34-37
Background: Association studies between the vitamin D deficiency (VDD) and hypothyroidism have given mixed results. Because of this controvery and relatively common prevalence of these two conditions, we conducted a case-control study investigating the prevalence of VDD in patients with hypothyroidism (both TPO-Ab positive and negative) and compared it with euthyroid controls. Methodology: This is a single centre cross sectional study. Adults (aged 18 years or more) of both the sexes diagnosed with primary hypothyroidism (TSH >5.1 mIU/L) were included (n = 115) along with age and sex matched euthyroid (TSH <5 mIU/ml) controls (n = 120) chosen from the outpatients' department. Biochemical parameters like Thyroid stimulating hormone (TSH), free T4 (fT4), 25 hydroxy vitamin D (Vit D) and thyroid peroxidase antibody (TPO-Ab) were tested in both the groups. Results: Patients in the hypothyroid group [38 (males) and 77 (females)] had a mean (SD) age 46 (15) years, while the euthyroid control group [24 (males) and 96 (females) had a mean (SD) age of 45 (17) years. In the hypothyroid group, 96% (110/115) had VDD as compared to 90% (108/120) in the control group with a significantly lower mean Vit D level was observed in the hypothyroid group as compared to the euthyroid group (12+8.6 vs 17.49+11.89 ng/ml; P < 0.001). While 27 cases with hypothyroidism had severe VDD (Vit D levels <4.2 ng/ml) only 10 among the control group had severe VDD (OR 2.04, CI: 1.03-4.05, P < 0.05)). The mean level of Vit D in the TPO-Ab positive hypothyroid group was 10.4+7.2 ng/ml in comparison to the TPO-Ab negative group 15.3+10.3 (P = 0.004) (OR 3.39, CI:1.18-9.80; P < 0.05) 3.62). Conclusion: The vitamin D levels in patients with hypothyroidism were significantly lower compared to euthyroid controls.TPO-Ab positive patients had lower levels of vitamin D in comparison with negative

Thyroid Research and Practice 2018 15(1):3-9
Objectives: The objective of this study is to study the demographic, clinicopathological features, and geographical distribution of differentiated thyroid cancer (DTC) among Libyan patients referred from all parts of the country to the nuclear medicine department, for radioactive iodine (RAI) therapy. Materials and Methods: Retrospective review of medical records of 265 patients with differentiated thyroid carcinoma (DTC) referred to RAI therapy in the Nuclear Medicine Branch-Tripoli Medical Center, in the period from May 2005 to October 2010. The data analyzed included sex, age at the time of diagnosis, the city of residence, pathological diagnosis, the extent of disease, and types of treatment. Results: There were 225 (84.9%) females and 40 (15.1%) males giving a sex ratio of 5.6:1. The mean age of males at diagnosis was 51.2 ± 14.8 (range 24–78) years and the mean age of the females was 44.6 ± 15.6 (range 10–95) years. Two hundred and twenty-three (84.2%) had papillary thyroid cancer (PTC), 31 (11.7%) had follicular thyroid cancer, 3 (1.1%) had Hurthle cell thyroid cancer, and 2 (0.8%) had follicular-insular thyroid cancer. About 43 (16.2%) had a history of multinodular goiter, and 3 (1.1%) Hashimoto's thyroiditis. From data collected, cervical lymph node metastases were found in 45 (17.0%), and distal metastases in 27 (10.2%). Conclusions: PTC was the most common type of DTC. DTC was more common among females. The current study showed that the disease tends to occur at an older age, and with less cervical lymph node metastases than previously reported.

Depression, anxiety, and somatization in patients with clinical and subclinical hypothyroidism: An exploratory study
Thyroid Research and Practice 2018 15(1):10-14
Background: Hypothyroidism and subclinical hypothyroidism (SCHT) are common disorders seen in clinical practice. A large proportion of patients with these disorders show psychiatric comorbidity. The current study was carried out to assess the prevalence and proportion of depression, anxiety, and somatization symptoms and compare the same between these two groups of patients. Methodology: Patients attending a medical outpatient department were screened for thyroid dysfunction using laboratory parameters, and patients detected with clinical and SCHT were included in the study. The sample consisted of 34 patients with CHT and 36 patients with SCHT. The patients were administered the Hamilton Rating Scale for Depression, Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder-7 Questionnaire, and PHQ-15 for somatization. The data were analyzed statistically using computerized software. Results: The study groups were well matched on sociodemographic profile and basic data. On assessing the severity of depression and anxiety, more cases of mild depression were reported in the subclinical hypothyroid group compared to moderate and severe depression being higher in the clinical hypothyroid group (P = 0.0001). Anxiety was well matched in both groups while somatization was higher in the subclinical hypothyroid group (P = 0.0001). Scores on depression scales were higher in the clinical group (P = 0.0001) and anxiety and somatization scores were higher in the subclinical group (P = 0.0001). Conclusions: Depression is usually seen in CHT while anxiety and somatization may be greater in SCHT. Further studies in larger populations are needed to validate the findings.

A cross-sectional survey to assess knowledge, attitude, and practices in patients with hypothyroidism in India
Thyroid Research and Practice 2018 15(1):15-22
Objective: The objective of this study is to assess the knowledge, attitude, and practices (KAP) in patients with hypothyroidism in India. Methods: This was a questionnaire-based, cross-sectional KAP study conducted in patients with hypothyroidism across 16 centers in India. The questionnaire was validated initially by a panel of experts, followed by 120 patients with primary hypothyroidism. Results: Out of 500 patients enrolled, about three-fourths (72.4%) were women. Most patients had low levels of knowledge (66.6%), were quite concerned (46.6%), and practiced a moderate level of precaution (77.8%). Around 18.4%, 26.2%, 27.8%, and 37.6% of patients had incorrect/no knowledge that weight gain, fatigue, muscle aches/pain, and dry skin were effects of hypothyroidism, respectively. Patients had poor knowledge regarding various risks associated with hypothyroidism such as abnormal menstruation (41.6%), depression (47%), hypercholesterolemia (65.6%), and medications causing hypothyroidism (74.2%). Most patients (91.4%) affirmed the need to consult a physician for or seek medical advice before treatment initiation. However, a small percentage did not agree on testing pregnant women (20.2%) and family members (26.2%) for hypothyroidism. Most patients (93.2% and 92.6%) practiced compliance to frequency and timings for medications; however, one-thirds reported missing doses. There was lack of knowledge-seeking behavior both from online sources (57.4%) and treating doctors (24.2%). Significant associations were found between education and the levels of knowledge, concern, and precautions taken. Conclusion: This study identified significant gaps in the knowledge about the risks associated with hypothyroidism, importance of laboratory investigation, and dietary precautions.

Clinicopathological study of medullary carcinoma of thyroid: A single institute experience
Thyroid Research and Practice 2018 15(1):38-41
Context: Medullary thyroid carcinoma is one of the rare thyroid malignancies representing only about 5%–10%of total thyroid cancers. Aims: To study the age, sex distribution, and various histopathological features of medullary carcinoma of thyroid in our institute over a period of 5 years. Settings and Design: This is a retrospective descriptional study of the cases diagnosed as medullary carcinoma over a period of 5 years in our institute (i.e., from April 01, 2010, to March 31, 2015). Subjects and Methods: The study material obtained from departmental records, gross specimens, paraffin blocks or slides and case files from medical record sections. Histopathologically, tumor was identified according to the classical features as described in the World Health Organization of classification of tumors of endocrine organs. Results: We found 20 cases of medullary carcinoma which accounted for 12% of thyroid malignancies. There was female dominance, and the age group of patients ranged from 20 years to 66 years. Microscopically, tumor cell arrangement was classic in all the cases with some showing pseudopapillary and spindle cell areas. Apoptosis of the tumor cells were seen notably in three cases. Three cases had necrotic areas. One case of micro medullary carcinoma was found incidentally. We had one interesting case where the clinical and cytological features were more in favor of papillary carcinoma. Conclusions: Medullary carcinoma of the thyroid is rare. Identifying the histopathological features and its variations may show light into understanding of the tumor biology with its implications on patient management and prognosis.

Vitamin D levels in children with Hashimoto's thyroiditis: Before and after L-thyroxine therapy
Thyroid Research and Practice 2018 15(1):23-28
Background: Vitamin D deficiency has been associated with Hashimoto's thyroiditis (HT). Hypothyroidism per se can cause poor absorption and metabolism of Vitamin D leading to Vitamin D deficiency. It is unknown that Vitamin D deficiency in HT is a cause or effect of HT. Objectives: To study Vitamin D level in children with newly diagnosed HT and to follow the changes in Vitamin D level after L-thyroxine therapy. Material and Methods: A prospective observational study was conducted on 35 children recently diagnosed with HT who had not received Vitamin D supplementation in the past 6 months. Serum 25 hydroxy Vitamin D levels along with serum calcium profile were estimated before starting L-thyroxine and on follow-up after 3 months. Results: The mean Vitamin D level at diagnosis of HT was significantly low as compared to controls (33.34 ± 16.93 nmol/L vs. 65.13 ± 30.57 nmol/L; P < 0.0001). Out of 22 Vitamin D-deficient patients who were treated, seven (31.8%) remained deficient at follow-up. Thirteen patients (sufficient/insufficient Vitamin D levels) who were not supplemented with Vitamin D had fall in Vitamin D levels in follow-up. Conclusions: Children with HT have low Vitamin D levels at diagnosis, and L-thyroxine therapy can further compromise Vitamin D status. Children with recent diagnosis of HT should be screened and treated or supplemented with Vitamin D.

Case report: An unusual variation in the course of recurrent laryngeal nerve in relation to the thyroid gland
Thyroid Research and Practice 2018 15(1):46-48
A complete understanding of the anatomic variations of the thyroid gland is necessary for a safe thyroid surgery. Injury to recurrent laryngeal nerve during thyroid surgery remains a significant source of morbidity. We present an uncommon variation in the position of right recurrent laryngeal nerve with the Tubercle of Zuckerkandl in a 40-year-old female who underwent thyroidectomy for a benign multinodular goiter. Identification and meticulous dissection of the Tubercle of Zuckerkandl and recognition of its association with the recurrent laryngeal nerve are essential to maintain the integrity of the nerve and prevent complications during thyroid surgery.

Spectrum of clinical symptomatology and its resolution following levothyroxine supplementation in primary and subclinical hypothyroidism: An Indian perspective
Thyroid Research and Practice 2018 15(1):29-33
Background: Data are scant on the spectrum of features associated with subclinical hypothyroidism (ScH) and overt primary hypothyroidism (OPH). This study aimed was to determine the burden as well as predictors of the lack of resolution of symptoms of hypothyroidism in patients of ScH and OPH following levothyroxine supplementation. Methods: A total of 505 patients were screened, of which 411 consecutive patients with ScH and 94 with OPH were evaluated. Data from 347 patients with ScH and 76 patients with overt OPH, who completed the study, were analyzed. Thyroid symptomatology was evaluated using standardized questionnaire. Results: The median age of participants was 35 (28–41) years; 95.04% being females. Common symptoms in OPH were shortness of breath (72.36%), depression (57.89%), irritability (57.89%), periorbital edema (53.94%), "feeling tired" (51.31%), and swelling of limbs (48.68%). Common symptoms in ScH were "feeling tired" (62.82%), "unhappy with routine" (44.95%), depression (40.92%), irritability (38.90%), and "weight gain with a poor appetite" (36.31%). Goiter was documented in 31.58% OPH and 3.17% in ScH (P < 0.001). Hair loss was observed 31.57% OPH and 29.68% ScH. Median (interquartile range) dose of levothyroxine supplemented was 37.5 (12.5–50) and 100 (75–112.5) mcg, respectively. Resolution of hypothyroidism symptoms was lesser in ScH. Persisting features included goiter, irregular menstruation, "weight gain with poor appetite," irritability, depression, "feeling tired," body aches, and depression. Binary logistic regression revealed thyroid stimulating hormone (TSH) to be an independent predictor of symptoms resolution. Every unit increase in TSH was associated with 0.7% greater resolution. Conclusion: Symptoms associated with hypothyroidism are diverse and nonspecific. Resolution of symptoms following levothyroxine supplementation and achieving biochemical euthyroidism is more likely in OPH that ScH.

Steroid-responsive encephalopathy in autoimmune thyroiditis: A diagnostic enigma?
Thyroid Research and Practice 2018 15(1):52-55
Hashimoto's encephalopathy or steroid-responsive encephalopathy associated with autoimmune thyroiditis is a neuroendocrine disorder of unknown cause associated with thyroid autoimmunity. We report case of a 61-year-old male, previously healthy, who developed a subacute onset of declining higher mental functions. Serologic studies demonstrated the high levels of antithyroid antibodies. Electroencephalographic, cerebrospinal fluid, and magnetic resonance image findings were normal, consistent with Hashimoto's encephalopathy. It is a diagnosis of exclusion once the detailed neurology evaluations were done. This unusual disorder is often underrecognized because of the multiple and protracted neurocognitive manifestations; therefore, it is important to be aware of this clinical manifestations to make a correct diagnosis and favorable outcome.

Periodontal and endodontic infectious/inflammatory profile in primary periodontal lesions with secondary endodontic involvement after a calcium hydroxide-based intracanal medication
Abstract
Objective
The aim of the present study was to investigate the effects of a calcium hydroxide-based intracanal medication (ICM) on periodontal and endodontic infectious/inflammatory contents and on periodontal clinical parameters in teeth with primary periodontal lesion and secondary endodontic involvement.
Materials and methods
Ten patients with abnormal pulp test results and deep probing depth derived from primary periodontal disease with secondary endodontic involvement were included. Samples were collected from root canals (RC) and periodontal pockets (PP) in order to investigate the microbiological status, levels of endotoxin (LPS), cytokines, and matrix metalloproteinases (MMP), before and after ICM. PCR was used for microbiological assessment. The kinetic-chromogenic LAL assay was used for LPS quantification. Quantikine ELISA kits were used for measurement of IL-1 α, IL-1 β, TNF-α, PGE2, MMP-2, MMP-3, MMP-8, MMP-9, and MMP-13 levels. The statistical analyses were made using the Friedman and Wilcoxon tests (p < 0.05). T test was used to compare data on periodontal characteristics.
Results
ICM did not reduce the number of microorganisms in PP and RC, except for Fusobacterium nucleatum in RC. There was a significant reduction in LPS, MMPs, IL-1 β, and TNF-α levels in PP after ICM. In RC, LPS, MMP13, PGE2, and IL-1β levels remained unaltered (p > 0.05); however, the levels of the other MMPs and cytokines were reduced (p < 0.05). After 1 year of the root canal treatment, tooth mobility was significantly reduced (p ≤ 0.05).
Conclusions
The use of a calcium hydroxide-based ICM showed positive effects for periodontal treatment prognosis, as it reduced LPS, cytokine, and MMP levels in periodontal pockets.
Clinical significance
Patients presenting deep probing depth and undergoing periodontal treatment for at least 6 months, with no positive response to periodontal therapy, might benefit with the endodontic treatment.

Author(s): A. Sindel, A. Sayan, Ö. Özgür, T. Sindel, V. Ilankovan
The aim of this study was to evaluate the efficacy of fluoroscopy-guided percutaneous injection of bleomycin as the primary treatment for low-flow vascular malformations. A total of 34 patients (mean (range) age 24 (8–51) years) with orofacial vascular lesions were treated in the Department of Interventional Radiology and Maxillofacial Surgery. There were 20 low-flow venous malformations, 11 lymphatic malformations, and three of mixed type. All patients were treated by fluoroscopy-guided percutaneous injection of a mixture of bleomycin (mean (range) 15 (5–15)mg) and a radio-opaque agent (Ultravist® (iopromide), Bayer)/session. The number of sessions ranged from one to six. The clinical response was complete in 21 patients, obvious in nine, and of clinical benefit in four. Patients were reviewed within the first week, third week, and at three-month periods until 24 months. There were no serious complications such as pulmonary fibrosis. Fluoroscopy-guided intralesional injection of bleomycin should be considered as the first-line treatment for lymphatic malformations because it is effective and reliable with few complications.

Survivorship care plans: are randomized controlled trials assessing outcomes that are relevant to stakeholders?
Abstract
Purpose
The purpose of this study was to compare outcomes assessed in extant randomized controlled trials (RCTs) to outcomes that stakeholders expect from survivorship care plans (SCPs). To facilitate the transition from active treatment to follow-up care for the 15.5 million US cancer survivors, many organizations require SCP use. However, results of several RCTs of SCPs' effectiveness have been null, possibly because they have evaluated outcomes on which SCPs should be expected to have limited influence. Stakeholders (e.g., survivors, oncologists) may expect outcomes that differ from RCTs' outcomes.
Methods
We identified RCTs' outcomes using a PubMed literature review. We identified outcomes that stakeholders expect from SCPs using semistructured interviews with stakeholders in three healthcare systems in the USA and Canada. Finally, we mapped RCTs' outcomes onto stakeholder-identified outcomes.
Results
RCT outcomes did not fully address outcomes that stakeholders expected from SCPs, and RCTs assessed outcomes that stakeholders did not expect from SCPs. RCTs often assessed outcomes only from survivors' perspectives.
Conclusions
RCTs of SCPs' effectiveness have not assessed outcomes that stakeholders expect. To better understand SCPs' effectiveness, future RCTs should assess outcomes of SCP use that are relevant from the perspective of multiple stakeholders.
Implications for Cancer Survivors
SCPs' effectiveness may be optimized when used with an eye toward outcomes that stakeholders expect from SCPs. For survivors, this means using SCPs as a map to guide them with respect to what kind of follow-up care they should seek, when they should seek it, and from whom they should seek it.

ObjectivesThis is a 27-year study of a cohort of 5708 patients who sustained maxillofacial fractures. Our purpose is to present the aetiology, mechanism of trauma, site and concomitant injuries that led to visual loss. We hypothesize that fractures caused by high energy impact of the midface may be associated with blindness. A discussion of the treatment approaches is also included.Study Design5708 patients sustained a maxillofacial fracture during the years from 1985 to 2012 and were included in this study. Patients' records were reviewed for gender, age, fracture site, aetiology of trauma, concomitant injuries, method of treatment, length of hospital stay and cause of blindness. The relation of the above variables to blindness was investigated.ResultsThe incidence of loss of vision was 0.34%. A very strong association between firearm injuries and blindness is demonstrated. (p<0.001) These patients spent much longer time in hospital (p<0.01) and suffered serious concomitant injuries involving the brain.ConclusionRetrobullbar haemorrhage should be treated with lateral canthotomy whereas in traumatic optic neuropathy, observation seems to be the safest thing to do. In patients with penetrating injuries of the globe the immediate involvement of an Ophthalmic Surgeon is of paramount importance.

Demographics and referral patterns of a university-based oral maxillofacial radiology clinic over a 20 year period
Publication date: Available online 23 March 2018

Author(s): Chen Nadler, Linda Lee
Objectives– The aim of this study was to review the referral patterns, distribution of interpretations, and type of diagnostic imaging used in a university based oral maxillofacial radiology clinic for patients referred for consultation from both dental and non-dental clinicians.Study Design– The database of the Special Procedures clinic in the Oral Radiology department of the University of Toronto, Faculty of Dentistry, containing over 5,000 entries, from 1993 to 2013, was queried. Using descriptive categorical analysis, the results were analyzed to describe patient demographics, the speciality of the referring clinicians, the imaging modalities used and the interpretation provided.Results– Most referrals were from oral and maxillofacial surgeons and general dentists. Approximately 25% of referrals were interpreted as variations of normal anatomic structures. The most common reasons for referral were intraosseous lesions (42%), temporomandibular joints (39%), and sialography. Ten per cent of all referrals were for recall examinations. The distribution of image modalities has changed through the years covered by this study.Conclusion– This study reflects a lower proportion of referrals reported as normal structures and their variations, than reported in a previous comparable study.

Abstract
Endoscopic skull base surgery has developed rapidly over the last decade, in large part because of the expanding armamentarium of endoscopic repair techniques. This article reviews the available technologies and techniques, including vascularized and nonvascularized flaps, synthetic grafts, sealants and glues, and multilayer reconstruction. Understanding which of these repair methods is appropriate and under what circumstances is paramount to achieving success in this challenging but rewarding field. A graduated approach to skull base reconstruction is presented to provide a systematic framework to guide selection of repair technique to ensure a successful outcome while minimizing morbidity for the patient.

Facial reanimation provides patients affected by chronic facial paralysis a chance to regain basic human functions such as emotional expression, verbal communication, and oral competence for eating and swallowing, but there is still no consensus as to the best way to measure surgical outcomes. We performed a literature review to investigate the different functional outcomes that surgeons use to evaluate facial function after reanimation surgery, focusing on outcomes other than facial expressions such as speech, oral competence, and patient quality of life/satisfaction. A total of 37 articles were reviewed, with the majority reporting outcomes through subjective facial expression ratings and only 15 dealing with other functional outcomes. In particular, outcomes related to oral competence and speech were reported inconsistently. Facial reanimation patients would benefit from a unified movement to create and validate through consensus, an outcomes reporting system incorporating not only facial expression, but also oral competence, speech, and patient-reported quality of life, to enable global patient assessment.

Radioiodine Refractory Differentiated Thyroid Cancer
Publication date: Available online 22 March 2018
Source:Critical Reviews in Oncology/Hematology
Author(s): Yuchen Jin, Douglas Van Nostrand, Lingxiao Cheng, Min Liu, Libo Chen
Differentiated thyroid cancer (DTC) is usually curable with surgery, radioactive iodine (RAI), and thyroid-stimulating hormone (TSH) suppression. However, local recurrence and/or distant metastases occur in approximately 15% of cases during follow-up, and nearly two-thirds of these patients will become RAI-refractory (RR-DTC) with a poor prognosis. This review focuses on the most challenging and rapidly evolving aspects of RR-DTC, and we discuss the considerable improvement in more accurately defining RR-DTC, more effective therapeutic strategies, and describe the diagnosis, pathogenesis, and future prospects of RR-DTC. Along with the detection of serum thyroglobulin and anatomic imaging modalities, such as ultrasound and computer tomography, radionuclide molecular imaging plays a vital role in the evaluation of RR-DTC. In addition, continual progress has been made in the management of RR-DTC, including watchful waiting under appropriate TSH suppression, local treatment approaches, and systemic therapies (molecular targeted therapy, redifferentiation therapy, gene therapy, and cancer immunotherapy). These all hold promise to change the natural history of RR-DTC.
