Assessing the Burden of COVID-19 among Children Aged 6-14 Years in Karnataka, India: A Cross-sectional Survey.

Background: India experienced three coronavirus disease (COVID-19) waves, with the third attributed to the highly contagious Omicron variant. Before the national vaccination rollout for children above 6, understanding severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) immunoglobulin G (IgG) positivity in the pediatric population was essential. This study aims to assess the burden of Covid-19 infection and to estimate the seroprevalence in children aged 6 to 14 years in the state of Karnataka. Material and Methods: We surveyed 5,358 children aged 6-14 across Karnataka using 232 health facilities, from June 6 to 14, 2022. We determined the sample size using the PPS (Population Proportional to Size) technique and employed cluster sampling. We tested all participants for SARS-CoV-2 IgG with an enzyme-linked immunosorbent assay (ELISA) kit and SARS-CoV-2 RNA with reverse transcription-polymerase chain reaction (RT-PCR). We sequenced samples with a cycle threshold (CT) value below 25 using whole genomic sequencing (WGS). Result: We found an adjusted seroprevalence of IgG at 75.38% statewide, and we found 0.04% of children RT-PCR positive for COVID-19. We determined a case-to-infection ratio of 1:37 and identified the SARS-CoV-2 strains as Omicron, BA.5, and BA.2.10. Conclusion: The study showed a high seroprevalence of IgG among children with low active infection. Omicron, BA. 5, and BA. 2.10 variants were detected through WGS.

Quality of a life skills training program in Karnataka, India - a quasi experimental study.

BACKGROUND: Youth focused Life Skills Education and Counseling Services (YLSECS) program, trained teachers/National Service Scheme (NSS) officers to deliver Life Skills Education (LSE) and counseling services to college going youth in the state of Karnataka in India. Available evaluation of life-skills training program have neglected the recording and or reporting of outcome among those trained to implement life-skills training program. Present paper highlights the quality of YLSECS training program and change in perception among teachers/NSS-officers trained in-terms of improvement in their cognitive/affective domains. METHODS: YLSECS program focused on World Health Organization identified ten essential domains of life-skills. Participants of the YLSECS program were trained by adopting facilitatory approach based on the principles of Kolb's learning theory. Quasi experimental study design was used to evaluate the outcome of training among participants. Quality of the training was assessed using scoring system and change in perception was assessed using Likert scale. Statistical significance of change in perception before and after training was assessed by paired't' test for proportion. RESULTS: Overall, 792 participants rated the quality of training as either "good" or "excellent". Post-training, significant (p < 0.001) proportion of the participants reported improved awareness about life-skills (before training 49.9 to 74.4% vs post-training range from 91.6 to 95.1% for various domains). There was statistically significant (p < 0.001) increase in participants reporting "very confident" in teaching various life skill domains (before training from 22.7 to 34.2% for various domains and post-training it ranged from 65.2 to 74.7% for various domains). There was modest increase in participants reporting perceived ability to conduct life-skills workshop "without assistance" post-training (before training from 16.8 to 22.9% for various domains vs post-training ranged from 29.8 to 36.8% for various domains). Interestingly, considerable proportion of participants who prior to training reported being confident in providing life skills training (without any assistance), later (i.e post training) reported they need some/more assistance for the same. CONCLUSION: YLSECS training program significantly improved participants knowledge and confidence in imparting life-skills and highlight the need for continued handholding of participants for effective implementation of LSE and counseling service program.

Improving Bethesda Reporting in Thyroid Cytology: A Team Effort Goes a Long Way and Still Miles to Go .

CONTEXT: Fine-needle aspiration cytology is the first step in evaluation of thyroid nodules. Although the Bethesda classification for reporting thyroid cytology has been purported that this uniformity in reporting cytology thereby facilitating clinical decision-making, there are also studies indicating that the reporting percentage and the rates of malignancy in each category vary considerably from center to center making the clinical decision more difficult. AIM AND MATERIALS AND METHODS: We looked at our retrospective cytology and histopathology data of thyroid nodules operated between 2012 and 2014 and then prospectively collected data during 2015-2016. In the prospective arm, for every thyroid nodule that was sampled, there was a discussion between the endocrinologist and the cytopathologist on the risk of thyroid cancer (based on the patient's history, examination findings, sonographic pattern, and the cytological appearance). RESULTS: We noted that there was considerable improvement in reporting standards with the rates of nondiagnostic cytology dropping from 11% to 5%, an increased reporting of Bethesda Category 2 and 6 which are the definitive strata of benign and malignant nodules (38% to 41% in Category 2 and 7% to 11% in Category 6) with a high specificity (100%). There was a decline in numbers of Category 4 and 5 (13% to 9% in Category 4 and 12% to 3% in Category 5). The reporting prevalence of Category 3 increased from 19% to 27%. CONCLUSIONS: We conclude that a team approach between the clinician who performs the ultrasound and the reporting cytopathologist improves Bethesda reporting, its predictive value, and thus potentially avoiding unnecessary thyroidectomies in benign thyroid nodules and hemithyroidectomies in thyroid cancers.

Infantile Fibromatosis: A Rare Cause of Anterior Mediastinal Mass in a Child.

Fibromatosis also known as desmoid tumor is an uncommon cause of a mediastinal mass in patients of all ages. Imaging appearance of fibromatosis is generally nonspecific and demands special attention to subtle details to be correctly identified as a possibility. Management of the patient is often complicated by failure to obtain precise pre-operative diagnosis. Location of a mass in the anterior mediastinum with encasement of vital structures is not favourable for complete cure. Although histologically benign, biological behaviour of the lesion varies between benign fibrous proliferation and low-grade fibrosarcoma. We present imaging appearances, surgical management dilemma, and the histopathological details of a case of fibromatosis in the anterior mediastinum in a child.

Malignant variant of sclerosing perivascular epithelioid cell tumor arising in the adnexa.

The perivascular epithelioid cell family of tumors (PEComas) includes angiomyolipoma, lymphangioleiomyomatosis, clear-cell "sugar" tumor of the lung and a variety of extrapulmonary epithelioid and spindle-cell tumors referred to by various names. PEComas are now widely recognized histologically, and have been reported to occur at most anatomical sites, including the female genital tract. However, a distinctive variant of PEComa, designated "sclerosing PEComa," has only recently been described in the literature. All 13 of the cases of sclerosing PEComa reported thus far have been in women (mean age of 49 y), with a predilection for the retroperitoneum. Only one of the reported cases showed transition to a high-grade malignant phenotype. We report the first case of sclerosing PEComa arising in the uterine adnexa, with high-grade malignant transformation.
