Risk Factors of Pelvic Floor Disorders Among Women in Rural Nepal: A Case-Control Study.

INTRODUCTION AND HYPOTHESIS: Risk factors for pelvic floor disorders (PFDs) are not well understood in lower resource settings. The objective of this study is to determine the risk factors associated with stress urinary incontinence (SUI), urge urinary incontinence (UUI), and pelvic organ prolapse (POP) among women of reproductive age in rural Nepal. METHODS: This is a case-control study nested within a community-based cross-sectional survey of parous women of reproductive age with PFDs in the Sarlahi District of Nepal. The presence of PFDs was confirmed by clinical assessment. Detailed sociodemographic information and histories were captured. RESULTS: We examined 406 women; the mean (SD, range) age was 32.7 (8.5, 16-49) years, mean BMI (SD) was 19.7 (3.3) kg/m2, and median (range) number of pregnancies was 4 (1-11). Two hundred and three women (50.0%) had either SUI or UUI, 85 (17.8%) had both SUI and UUI, and 71 (17.5%) had POP at or beyond the hymen. After controlling for other variables significant on bivariate analysis, age (adjusted odds ratio [aOR] 1.06 [95% CI 1.03-1.09]), illiteracy (aOR 2.24 [95% CI 1.04-4.80]), and presence of upper gastrointestinal issues (aOR 3.30, [95% CI 1.77-6.16]) were independently associated with SUI/UUI. Age (aOR 1.05 [95% CI 1.02-1.09]), bispinous diameter (aOR 2.88 ([95% CI 1.11-7.47]), and subpubic angle (aOR 2.78 [95% CI 1.55-5.03]) were independently associated with POP. CONCLUSION: Risk factors for PFDs in a homogenous community of parous women of reproductive age in rural Nepal are similar to those found in parous women in higher income countries.

Categorisation of peritoneal serous effusions using the International System for Reporting Serous Fluid Cytopathology-A study on gynaecological samples.

BACKGROUND: Cytology of serous effusions is an indispensable diagnostic tool for the diagnosis of non-neoplastic as well as neoplastic effusions, aiding in the categorisation, staging, and prognostication of the patient. This study focuses on reclassifying cases of peritoneal fluid cytology following the International System for Reporting Serous Fluid Cytopathology (TIS), highlighting various challenges encountered and adding to the body of data regarding the risk of malignancy (ROM), focussing on peritoneal effusions due to gynaecological causes. METHODS: Peritoneal effusion samples were retrieved from our department's archives and reclassified according to the TIS. The ROM for each category was calculated based on available surgical follow-up. RESULTS: A total of 818 peritoneal effusions were studied. Following the definitions and guidelines of the TIS, the cases were reclassified with 125 (15.2%) in the category of non-diagnostic (ND), 595 (72.7%) as negative for malignancy (NFM), 26 (3.2%) as atypia of undetermined significance (AUS), 12 (1.5%) as suspicious for malignancy (SFM), and 60 (7.3%) as malignant (MAL). The respective ROM values for each category were 16.9%, 12.1%, 50%, 80%, and 100%, respectively. By considering the MAL and SFM groups as positive, and the ND, NFM, and AUS groups as negative, the diagnostic accuracy, sensitivity, specificity, and positive and negative predictive values were determined as 85.2%, 36.7%, 99.1%, 91.7%, and 84.5%, respectively. CONCLUSIONS: Peritoneal cytology categorisation following the proposed TIS offered a practical approach for categorisation of the fluids received. The ROMs reported in our study were mostly concordant with those published according to the TIS.

Correlation of ultrasound-based TIRADS and the Bethesda system for reporting of thyroid cytopathology: A study in a tertiary care centre.

BACKGROUND: The age-standardised incidence rate of thyroid cancer in India is 1 in 416 in the general population. This increased incidence has mainly been attributed to improved detection methods for small thyroid lesions. Two such methods are the American College of Radiology Thyroid Imaging Reporting and Data System (ACR TIRADS) and the Bethesda System for Reporting Thyroid Cytopathology (TBSRTC). AIMS AND OBJECTIVES: To study the correlation between ACR TIRADS and TBSRTC, and between each system and the final histopathological report. MATERIALS AND METHODS: Thyroid cytopathology cases were retrieved for the period January 2019 to July 2022. For each case, the TIRADS score and Bethesda category were noted. Histopathology specimens were also traced. RESULTS: The study comprised 1100 cases, with 955 female and 145 male patients (M:F = 1:6.59), and ages ranging between 7 and 85 years. The TIRADS scoring was available for 1036 cases. Histopathology was available for 231 cases. There was a significant correlation between TIRADS and TBSRTC, with a p-value of 0.000 and a substantial Kappa agreement of 0.688. Both TIRADS and TBSRTC also had significant correlations with the histopathology data, with a p-value of 0.000 for each. The sensitivity values for TBSRTC and TIRADS were 69.4% and 65.8%; specificity, 99.3% and 96.5%; positive predictive value (PPV), 98.3% and 91.8%; and negative predictive value (NPV) 84.7% and 84.4%, respectively. The risk of malignancy (ROM) was also calculated and was found to be high, especially for TBSRTC II, III, IV and V (11.3%, 20%, 61.5%, 97.4% respectively) and TIRADS 2 and 3 (10.3% and 29.6% respectively). CONCLUSION: The TIRADS and TBSRTC systems of categorisation of thyroid lesions are concordant and could help improve the overall survival rate of patients with thyroid malignancies.

Androgen insensitivity syndrome: Can cytology help?

Androgen insensitivity syndrome (AIS) is described as a patient's clinical (phenotypical) presentation as a female with male karyotyping. Classically, patients are normal looking females with complaints of primary amenorrhea. The gonads may be found as extra-genital swellings; rarely, the testes may undergo malignant transformation. Thus, gonadectomy is indicated in these patients on attaining puberty. A rare and interesting case of clinically unsuspected AIS in a young female who presented with primary amenorrhea and inguinal swelling is reported. The initial diagnosis was suggested on fine needle aspiration cytology (FNAC) from the inguinal swelling that showed the presence of Sertoli cells. Further family history revealed two similar siblings; karyotyping and histopathology confirmed the diagnosis of AIS in the patient. This case highlights the importance of FNAC in early diagnosis and a multidisciplinary approach to confirm the diagnosis and help in appropriate management.

Sensitivity of liquid-based cytology in the diagnosis of mucormycosis in COVID-19 treated patients.

BACKGROUND: The coronavirus disease 2019 (COVID-19) infection caused by the novel severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) is associated with a wide range of disease patterns, ranging from mild to life-threatening pneumonia. COVID-19 can be associated with a suppressed immune response and/or hyperinflammatory state due to cytokine storm. Reduced immunity, combined with steroid usage to prevent cytokine storm along with various pre-existing co morbidities can prove to be a fertile ground for various secondary bacterial and fungal infection, including mucormycosis. Diagnosis of mucor is a challenging task given high negativity rate of various detection methods. While histopathology is considered the gold standard, the acquisition of necessary tissue biopsy specimens requires invasive procedures and is time consuming. METHOD: In this study various methods of mucor detection, like conventional cytopathology (CCP), liquid-based cytology (LBC, BD SurepathTM ), potassium hydroxide mount (KOH) preparation, culture and histopathology were analysed. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were calculated for various methods. RESULTS: This study showed that LBC has sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of 72.4%,100%,100% and 38.4% respectively. CONCLUSION: This study showed that, liquid-based cytology (LBC) can be a rapid and effective alternative to histopathology in mucor diagnosis.

COVID associated mucormycosis: A preliminary study from a dedicated COVID Hospital in Delhi.

BACKGROUND: It is an incontrovertible fact that the Rhino Orbital Cerebral Mucormycosis (ROCM) upsurge is being seen in the context of COVID-19 in India. Briefly presented is evidence that in patients with uncontrolled diabetes, a dysfunctional immune system due to SARS-COV-2 and injudicious use of corticosteroids may be largely responsible for this malady. OBJECTIVE: To find the possible impact of COVID 19 infection and various co-morbidities on occurrence of ROCM and demonstrate the outcome based on medical and surgical interventions. METHODOLOGY: Prospective longitudinal study included patients diagnosed with acute invasive fungal rhinosinusitis after a recent COVID-19 infection. Diagnostic nasal endoscopy (DNE) was performed on each patient and swabs were taken and sent for fungal KOH staining and microscopy. Medical management included Injection Liposomal Amphotericin B, Posaconazole and Voriconazole. Surgical treatment was restricted to patients with RT PCR negative results for COVID-19. Endoscopic, open, and combined approaches were utilized to eradicate infection. Follow-up for survived patients was maintained regularly for the first postoperative month. RESULTS: Out of total 131 patients, 111 patients had prior history of SARS COVID 19 infection, confirmed with a positive RT-PCR report and the rest 20 patients had no such history. Steroids were received as a part of treatment in 67 patients infected with COVID 19. Among 131 patients, 124 recovered, 1 worsened and 6 died. Out of 101 known diabetics, 98 recovered and 3 had fatal outcomes. 7 patients with previous history of COVID infection did not have any evidence of Diabetes mellitus, steroid intake or any other comorbidity. CONCLUSION: It can be concluded that ROCM upsurge seen in the context of COVID-19 in India was mainly seen in patients with uncontrolled diabetes, a dysfunctional immune system due to SARS-COV-2 infection and injudicious use of corticosteroids.

Osteoblastoma of the Distal Radius.

Osteoblastomas are rare, benign, bone-forming neoplasms that represent less than 1% of all bone tumors and occur mostly in people aged 10 to 30 years. In long bones, the metadiaphyseal region tends to be most commonly affected. However, to the best of our knowledge, only 11 cases have been reported to occur in the distal radius. We present the clinical, radiological, and histopathological findings of an osteoblastoma of the right distal radius in a 42-year-old woman for whom an open excisional biopsy with nidus removal comprised the treatment and produced a good outcome.

Association of E-cadherin & vimentin expression with clinicopathological parameters in lingual squamous cell carcinomas & their role in incomplete epithelial mesenchymal transition.

BACKGROUND & OBJECTIVES: Lingual squamous cell carcinomas (SCC) pose a major public health burden in India. Epithelial-mesenchymal transition (EMT) is the conversion of an epithelial cell to a mesenchymal phenotype at the invasive front (IF) enhancing invasiveness of these cells which may be studied using immunohistochemistry. The objective of this study was to assess the expression of E-cadherin and vimentin at the IF, and their correlation with the histological risk assessment score, clinicopathological parameters and lymph node metastasis. METHODS: Thirty consecutive untreated patients diagnosed as lingual SCC who underwent hemiglossectomy over one year formed the study group. The immunohistochemical expression of E-cadherin and vimentin in the periphery as well as the centre of tumour islands was correlated with clinicopathological parameters, Brandwein-Gensler risk assessment score and lymph node metastasis, along with a correlation between the coexpression of two markers at the IF. RESULTS: Loss of E-cadherin expression was seen at IF in 83.3 per cent (25/30) cases. Out of these, 20 per cent (5/25) showed a corresponding gain in vimentin expression (complete epithelial-mesenchymal transition) and 80 per cent (20/25) did not. Overall, 16.6 per cent (5/30) cases showed complete EMT. However, no correlation between E- cadherin and vimentin expression at the IF was found. No statistical significance was found between E-cadherin loss and vimentin gain at the IF, with the various parameters or the risk score. INTERPRETATION & CONCLUSIONS: The present study suggests that the cells at IF may metastasize even without a gain in vimentin expression (without classical EMT), as cohesive clusters showing incomplete EMT (E-cadh-/Vim-).

DLBCL of bilateral submandibular glands and MALToma of thyroid-A rare coexistence.

Involvement of the bilateral submandibular glands and thyroid by the same lymphoma simultaneously has been reported in the literature. However, two different types of lymphomas presenting simultaneously at different sites have never been reported. This case report highlights this rare occurrence. A 65-year-old female, a known case of Hashimoto's thyroiditis with raised anti-TPO antibodies, presented with thyroid swelling for 1 year and bilateral submandibular swelling for 3 years. FNAC and flow cytometry showed features of mucosa-associated lymphoid tissue lymphoma in the thyroid gland, whereas the bilateral submandibular glands showed features of diffuse large B cell lymphoma. Histopathology and immunohistochemistry from the submandibular swelling led to similar diagnoses as the flow cytometry.

Congenital Pulmonary Airway Malformation - A Histomorphological Spectrum of 15 Cases: A 5-Year Study from a Tertiary Care Center.

OBJECTIVE: Congenital pulmonary airway malformation (CPAM) is a rare developmental lung disease. The aim of this study is to analyze the histomorphological spectrum of CPAM in a series of 15 cases. MATERIALS AND METHODS: A retrospective descriptive study of 15 cases of CPAM was carried out from 2013 to 2018 in our hospital, and cases were classified based on the Stocker's classification. RESULTS: The age ranged from 4 days to 9 years (66.6% were infants). The left lung was most commonly involved (66.6%). The most common lobe was the left upper lobe (60%), followed by right lower lobe (20%). Grossly, cysts measured 0.2-5 cm, filled with mainly serous fluid with few having hemorrhagic and brownish mucoid secretions. On microscopy, single to multiple noncommunicating cysts of size 0.2-5 cm were seen, lined by ciliated columnar epithelium (60%), pseudostratified ciliated columnar epithelium (26.7%), mucin-secreting columnar epithelium (6.7%), and flattened epithelium (6.7%). Few cases showed smooth muscle (20%) and cartilage (13.3%) in the cyst wall. Chronic inflammation (73.3%) with dense histiocytic infiltrate (13.3%) was also seen. Emphysematous changes were also observed (13.3%). Cytomegalovirus inclusions (6.7%), zygomycete fungus (6.7%), and red hepatization (6.7%) were observed. The most common type was type II (60%), followed by type I (33.3%) and type IV (6.7%). CONCLUSION: Type II was the most common variant in this study. A careful observation should be done to look for fungal hyphae or viral inclusions.
