xlomafota13 shared this article with you from Inoreader

Acta Neurochir (Wien). 2022 Mar 16. doi: 10.1007/s00701-022-05178-x. Online ahead of print.

ABSTRACT

BACKGROUND: Olfactory neuroblastoma, also known as esthesioneuroblastoma, accounts for only 3-6% of sinonasal malignancies but confers a 40% 5-year overall survival.

METHOD: The authors describe techniques for the endonasal, minimally invasive resection of an esthesioneuroblastoma in a 69-year-old man who presented with headaches and anosmia and describe surgical nuances and their effect on adjuvant therapy planning.

CONCLUSION: This approach, along with microsurgical techniques, helped increase tumor visualization, improved marginal resection, and reduced surgical risk, which may improve patient outcomes. Multilayered reconstruction with a synthetic dural substitute and creation of a nasoseptal flap were performed to reduce postoperative cerebrospinal fluid leak.

Surg Radiol Anat. 2022 Mar 17. doi: 10.1007/s00276-022-02921-y. Online ahead of print.

ABSTRACT

PURPOSE: Olecranon fractures, especially with a small proximal fragment, remain a surgical challenge. Soft tissue irritation and affection of the triceps muscle bear a risk of complications. In order to find an area for a soft-tissue sparing placement of implants in the treatment of olecranon fractures, we aimed to define and measure the segments of the proximal olecranon and eval uate them regarding possible plate placement.

METHODS: We investigated 82 elbow joints. Ethical approval was obtained from the local ethics committee, After positioning in an arm holder and a posterior approach we described the morphology of the triceps footprint, evaluated and measured the surface area of the triceps and posterior capsule and correlated the results to easily measurable anatomical landmarks.

RESULTS: We found a bipartite insertional footprint with a superficial tendinous triceps insertion of 218.2 mm2 (± 41.2, range 124.7-343.2), a capsular insertion of 159.3 mm2 (± 30.2, range 99.0-232.1) and a deep, muscular triceps insertion area of 138.1 mm2 (± 30.2, range 79.9-227.5). Olecranon height was 26.7 mm (± 2.3, range 20.5-32.2), and olecranon width was 25.3 mm (± 2.4, range 20.9-30.4). Average correlation between the size of the deep insertion and ulnar (r = 0.314) and radial length (r = 0.298) was obtained.

CONC LUSIONS: We demonstrated the bipartite morphology of the distal triceps footprint and that the deep muscular triceps insertion area by its measured size could be a possible site for the placement of fracture fixations devices. The size correlates with ulnar and radial length.

Acupuncture and its effect on cytokine and chemokine profiles in seasonal allergic rhinitis: a preliminary three-armed, randomized, controlled trial

xlomafota13 shared this article with you from Inoreader

Eur Arch Otorhinolaryngol. 2022 Mar 17. doi: 10.1007/s00405-022-07335-5. Online ahead of print.

ABSTRACT

PURPOSE: Numerous studies have demonstrated effectiveness for acupuncture in the treatment of seasonal allergic rhinitis (SAR). However, the underlying mechanism remains still unclear.

METHODS: 29 SAR patients were recruited from a large randomized, controlled trial investigating the efficacy of acupuncture in SAR. 16 patients were treated by acupuncture plus rescue medication (RM, cetirizine), 6 patients received sham acupuncture plus RM and 8 patients RM alone over 8 weeks. Patients were blinded to the allocation to real or sham acupuncture. At baseline and different time-points during intervention, plasma and nasal concentration of mediators of various biological functions were determined in addition to validated disease-specific questionnaires.

RESULTS: The concentration of biomarkers related to the Th1-, Th2-, and T reg-cluster was not changed in patients who received acupuncture, in neither plasma nor nasal fluid. However, with respect to eotaxin and some unspecific pro-inflammatory cytokines (IL-1b, IL-8, IP-10, MIP-1b, MCP-1), acupuncture led to a, partially significantly, lower nasal concentration than sham acupuncture or RM. Furthermore, the nasal symptom score was significantly reduced in patients only after real acupuncture.

CONCLUSION: In SAR, acupuncture reduces the intranasal unspecific inflammation, but does not seem to act immunologically on the Th1-Th2-imbalance.

Abstract

Tonsillectomy is one of the most commonly performed surgical procedure in otolaryngology especially in children. This is an age old procedure which has seen continuous changes in the surgical technique from guillotine method to snare technique to coblation tonsillectomy, and is still evolving day by day. But there are no consensus as to which technique is the best or most appropriate for tonsillectomy. The objective of this study is to compare three different surgical techniques of tonsillectomy namely the Cold dissection snare technique (CDST), Bipolar electro-dissection technique (BEDT) and Harmonic scalpel technique (HST) and to identify the method which is safe, with less operative time, which offers decreased intra-operative blood loss and with lowest post-operative morbidity and complications. This prospective and comparative study was conducted over a time duration of 1 year 6 months from January 2018 to July 2019 after the approval from ethical committee. Total 150 cases of tonsillectomy were done by dividing into three groups of 50 cases each. The study showed maximum cases of tonsillitis in the age group less than 10 years and the most common indication for tonsillectomy being chronic recurrent tonsillitis. Harmonic scalpel technique (HST) had least operative time, least intra-operative blood loss, took minimum time for resumption of normal diet and normal activity and also had least pain score on post-operative day 1st, 5th, 10th and 15th. STATISTICS: Kruskall-Wallis and the non-parametric Analysis of variance (ANOVA) tests were applied to determine statistically significant variances. All the differences are found to be significant P < 0.05. Harmonic Scalpel Technique (HST) is the latest technique as it is associated with quicker procedure, less intraoperative blood loss and less post-operative pain.

Acta Otorhinolaryngol Ital. 2022 Feb;42(1):63-74. doi: 10.14639/0392-100X-N1561.

ABSTRACT

OBJECTIVE: Evaluate computed tomography (CT) signs that predict need for revision endoscopic sinus surgery (ESS) of chronic rhinosinusitis (CRS).

METHODS: CRS patients (n = 48) underwent routine sinus CT scans and baseline ESS in 2006-2011. Lund-Mackay (LM) scores and 43 other CT signs were analysed blinded from both sides. Patients filled in a questionnaire during the day of CT s canning. Follow-up data were collected from hospital records until January 2018. Associations were analysed by Fisher's exact, Mann Whitney U, Kaplan-Meier method with logrank test and Cox's proportional hazard model.

RESULTS: Total LM score was not significantly associated with the need for revision ESS. The best predictive model was a sum of CT signs of non-detectable anatomy of inferior/middle turbinates, obstructed frontal recess, and previous sinus surgery. Using these CT findings, we formed a Radiological Score (RS) (min-max, 0-3 points). Having at least one RS point was significantly associated with the need for revision ESS during the average follow-up of 10.7 years (p = 0.008, Logrank test).

CONCLUSION: We identified a radiologic score that was able to predict the need for revision ESS, which is probably useful in predicting CRS outcomes.

pubmed-meta-image.png

J Oral Facial Pain Headache. 2022 Winter;36(1):26-35. doi: 10.11607/ofph.3048.

ABSTRACT

AIMS: To investigate how trait anxiety and stress jointly affect the sensory and jaw motor responses to a tonic orofacial nociceptive stimulus.

METHODS: Orthodontic separators were placed between the first molars in 45 adults with low (n = 14), intermediate (n = 17), and high (n = 14) trait anxiety. Tooth pain, occlusal discomfort, tooth clenching (as a jaw motor behavior), and situ ational stress were measured three times a day for 5 days using visual analog scales. Mixed-effects regression models were used to evaluate the sensory and motor outcome measures.

RESULTS: Pain, discomfort, and frequency of tooth-clenching trajectories were affected by trait anxiety (P = .007, P < .001, and P = .055, respectively) and stress (P < .001, P < .001, and P = .044, respectively). Individuals with high anxiety reported their highest pain (17.7 ± 2.9 mm) and discomfort (35.2 ± 4.1 mm) 24 hours earlier than those with low anxiety (pain: 15.9 ± 2.6 mm, discomfort: 28.8 ± 3.7 mm). Tooth clenching decreased progressively in response to the stimulus (P < .001).

CONCLUSION: A tonic orofacial nociceptive stimulus triggers an avoidance jaw motor behavior. Both trait anxiety and situational stress heighten the sensory response to such a stimulus, but weakly affect the motor response to it.

Immunophenotypic characteristics of T lineage acute lymphoblastic leukemia: absence of immaturity markers-TdT, CD34 and HLADR is not uncommon

xlomafota13 shared this article with you from Inoreader

Am J Blood Res. 2022 Feb 15;12(1):1-10. eCollection 2022.

ABSTRACT

INTRODUCTION: T ALL may show variable morphological features and immunophenotypic analysis for characterisation of immature nature of these cells is needed to establish a diagnosis and distinguish from reactive conditions and mature T cell leukemias. Sometimes immaturity markers-CD34, TdT and HLA DR may not be expressed by blasts. The aim of the present study was to analyse immunophenotype of T ALLs especially with respect to absence of immaturity markers.

METHODS: Thirty-eight cases of T ALL diagnosed over a period of two and half years were analysed retrospectively with respect to clinical features, haematological features and flow cytometric immunophenotyping for T, B, Myeloid and immaturity markers. Student's T-test was used for comparing quantitative data and Chi-square test/Fishers exact T-test for qualitative variables. P value less tha n 0.05 was considered significant.

RESULTS: The most common T-lineage marker expressed was cCD3 and CD7 which were expressed in 100% cases followed by CD5 in 86.8% cases. The most common immaturity marker expressed was TdT (39.5% cases) followed by CD34 (34.2% cases). Thirteen cases (34.2%) were negative for all three of the immaturity markers i.e. TdT-/CD34-/HLADR. Absence of CD34 was associated with absence of expression of HLA DR (P<0.05) and aberrant expression of B lineage markers (P<0.05).

CONCLUSION: T-ALL is a rare and aggressive disease. Many cases lack immaturity markers viz, TdT, CD34 and HLADR. In such cases a comprehensive approach taking into account the clinical presentation, cytomorphology and immunophenotyping is diagnostic in experienced hands. Further, molecular studies may be needed to aid diagnosis.

Indications and outcomes for elective dissection of level V in primary parotid cancer

xlomafota13 shared this article with you from Inoreader

Abstract

Background

The extent of cervical lymphadenectomy required for primary parotid cancer is not well-established.

Methods

In this retrospective case–control study, 84 patients who underwent primary parotidectomy and neck dissection for primary parotid cancer between 2010 and 2019 were identified and analyzed.

Results

Of the 84 patients, 37 underwent elective level V neck dissection. All six (16.0%) who had occult level V nodes had clinically evident, preoperative anterior cervical metastases, a statistically significant finding. No other clinical factors are correlated with posterior neck involvement. There was no significant difference in disease-free or overall survival for patients with occult level V disease relative to positive lymph nodes in other levels.

Conclusions

Patients with clinically evident anterolateral cervical lymphatic metastases from parotid cancer preoperatively have high rates of occult level V nodes. Level V neck dissection can be avoided in cN0 patients and offered no survival advantage.

ABSTRACT

The effect of stress on the occurrence of diabetes mellitus (DM) is commonly reported in recent studies. Maternal stress may have a negative effect on the later life of offspring. However, most studies only investigated long-term intrauterine stress on behavioral, emotional, psychological, and immunological disorders of offspring. The relationship between maternal st ress and DM occurrence in the later life period of offspring is not known. This rat model study aimed to evaluate the susceptibility of offspring to DM after exposure to intrauterine stress. The purpose of this study is to examine serum glucose levels of mothers and offspring exposed to maternal stress and to evaluate pancreatic tissues pathologically and immunohistochemically. Twelve, Wistar Albino female rats were equally divided into two groups: controls and maternal stress groups. Normal routine conditions were applied to the control group without any stress. The pregnant rats in the maternal stress group were exposed to chronic unpredictable stressors throughout the 21-day gestation. One female and one male offspring and mothers from each term delivery were randomly selected and euthanatized at the 35th day. During the necropsy, blood and pancreatic tissue samples were collected from both mothers and pups. High serum glucose levels from mothers and offspring in the maternal str ess group and the control group were compared. Additionally, histopathological examinations assessed the increased cell degeneration in mother rats and offspring. Immunohistochemical examinations revealed decreased insulin, amylin, and insulin receptor expressions and slightly increased glucagon expression in Langerhans islet cells in the maternal stress group. These results indicated that maternal stress may be a predisposing factor for DM in both mothers and offspring in their later life periods.

Approach to gynecomastia and pseudogynecomastia surgical techniques and its outcome: a systematic review

xlomafota13 shared this article with you from Inoreader

J Plast Reconstr Aesthet Surg. 2022 Feb 20:S1748-6815(22)00079-1. doi: 10.1016/j.bjps.2022.02.008. Online ahead of print.

ABSTRACT

BACKGROUND: To date, various surgical techniques were developed for gynecomastia and pseudogynecomastia surgery, providing surgeons vast range of options. These variations of techniques, however, may have different efficacy and results depending on the severity of patients' conditions.

OBJECTIVES: This review aims to delineate comprehensively the variations of surgical approaches to gynecomastia and pseudogynecomastia in relation to surgical and patients' outcomes.

METHODS: Database search (October 28, 2020) from PubMed, Scopus, Science Direct, and Cochrane Library was performed to identify relevant studies using the keywords ("gynecomastia" OR "pseudogynecomastia") AND ("surgery" AND "mastectomy" OR "liposuction") within January 2011-November 2020, published in English. Inclusion criteria were approached according to patients, intervention, comparator, outcomes, and study design (PICOS). Data from the included studies were extracted based on study and subjects' characteristics, type of intervention, and outcome measures.

RESULTS: Out of all relevant studies revealed, 53 studies met inclusion criteria with 5345 subjects included. Most subjects, from 44 studies, were classified as Simon's Grade II (68.49%) with idiopathic cause (94.51%). Most cases were approached using the minimally invasive techniques (37.50%) and were highly satisfied. Among intervention groups, complication rates vary from 12.12-22.30%, with the minimally invasive approach having the lowest rate. Hematoma and bruise were the most reported complications. However, the risk of bias was relatively high due to missing data.

CONCLUSIONS: Different surgical approaches for gynecomastia treatment have been described and were consistent with good outcomes. To achieve a low rate of complications, the m inimally invasive techniques can be considered, since most patients seem to be satisfied.
