Traumatic abdominal intercostal hernia: A rare experience.

Traumatic abdominal intercostal hernias (AIHs) are an extremely rare surgical encounter, with amorphous literature. A case report of recurrent AIHs, evident only at surgery, and its management is presented. The inadequacy of experience and data translates to frequent missed diagnosis and suboptimal surgical management with high recurrence rates.

To compare the outcomes of pancreaticojejunostomy and pancreaticogastrostomy reconstruction after pancreaticoduodenectomy: A prospective observational study.

Background: We have been in constant search of novel innovations to decrease the high morbidity after Pancreaticoduodenectomy (PD). Pancreaticojejunostomy (PJ) and pancreaticogastrostomy (PG) are the two different methods of reconstruction after PD. However, the existing data is ambiguous in supporting either of them as the preferred technique of reconstruction. Methods: This was a single-center prospective observational study that included 64 patients who underwent PD over two years. We compared PG with PJ as a method of reconstruction after PD. The primary objective was to assess whether PG decreases the rate of postoperative pancreatic fistula (POPF) rates or not. Secondary objectives comprised analysis of perioperative outcomes, 30-day and 90-day mortality. Results: Pancreatic fistula was significantly lower in PG as compared to the PJ group (24% vs. 47%) with a p-value of 0.027. The incidence of clinically pertinent (grade B) fistula was only 3% in the PG group and 32% in the PJ group. PG group had a higher incidence of post pancreatectomy hemorrhage (PPH) and delayed gastric emptying (DGE). No statistically significant difference was seen between either group need for blood transfusion, re-exploration, re-admissions, ICU stay, or length of hospital stay, and 30-day and 90-day mortality. Pancreatic texture and high BMI were independent predictors for pancreatic fistula. Conclusion: PG when compared to PJ for reconstruction after PD, decreases the rate of POPF significantly; however, it is associated with an elevated risk of DGE and PPH. There was no difference in 30-day and 90-day mortality between both the treatment groups.

Findings of second multicentric follow-up serosurvey among Health Care Workers in government hospitals.

Background: The change in serological status of community may be used as input for guiding the public health policy. Hence, the present study was conducted to determine change in seroprevalence of COVID-19 among healthcare workers (HCWs). Methods: From the baseline multicentric study sample, a subsample was followed up, and a seroepidemiological study was conducted among them between 6 and 22 weeks after the second dose of the vaccination. Multistage population proportion to size sampling was performed for the selection of subsample of HCWs. The serosurvey was conducted using the enzyme-linked immunosorbent assay-based IgG antibody test (COVID KAVACH). Results: Follow-up serological testing was done in subsample of 1122 participants of original 3253 participants. The mean age of the participants was 34.6 (8.13) years. A total of 300 (26.7%) participants were females. The seroprevalence was 78.52, (95%CI:76-80.1). Among those who were seronegative at initial test, 708 (77.04%) were seroconverted. Those who were not seroconverted (241 (21.5%)) have longer duration from the second dose of the vaccination (93 (31.4) vs. 56 (38.4); p value < 0.001). The COVID-19 infection was significantly associated with seropositive status and being a medical staff was associated with remaining seronegative on follow-up. The higher age (≥50 years) was found to be significantly associated with seroreversion. Conclusion: Four in five HCWs had detectable antibodies. Seroepidemiological studies carry vital information to control the public health response in the course of the pandemic. The study can also further help as a platform to study the seroconversion and effect of vaccination among HCWs for newer variants of SARS-CoV-2.

Primary malignant melanoma of the gastroesophageal junction: A rare and unusual disease.

Malignant melanoma, an aggressive tumor of skin, is also seen rarely in extra cutaneous sites like the gastrointestinal tract (GIT). Primary melanoma of the GIT by itself is a rare tumor; often metastatic at presentation and if found non-metastatic, it is rarely resectable. We are reporting a histopathologically confirmed case of primary malignant melanoma affecting the 'gastroesophageal junction', which we operated on.

Seropositivity of severe acute respiratory syndrome coronavirus 2 infection among healthcare workers of the Armed Forces medical services, India: A multicentric study.

BACKGROUND: Serosurveys provide the prevalence of infection and over time will reveal the trends. The present study was conducted to estimate the seroprevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) among healthcare workers (HCWs) and to analyse various characteristics (risk factors) associated with SARS CoV-2 infection. METHODS: Eight government designated Corona virus disease -19 (COVID-19) hospitals were selected based on the hospital admission of patients with COVID-19 and the local epidemiological situation in the region. Multistage population proportion to size sampling was performed for the selection of HCWs. Serosurvey was conducted using the enzyme-linked immunosorbent assay-based IgG antibody test (COVID KAVACH). Bivariate and multiple logistic regression was performed to find out the factor/factors associated with the positive antibody test. RESULTS: Out of 3255 HCWs that participated in the study, data of 3253 were analysed. The seroprevalence was 19.7% (95% confidence interval: 18.5-21.3%). Factors associated were location, category of HCWs, male sex, previously tested positive by the molecular test, training on infection prevention and control, personal protective measures, handwashing technique, close contact with a patient confirmed with COVID-19, use of personal protective equipment and symptoms in the last 30 days. However, in multiple logistic regression, only location, category, previously tested positive by the molecular test and symptoms in the last 30 days were statistically significant. CONCLUSION: HCWs are vulnerable to SARS-CoV-2 infection. One in five HCWs had detectable antibodies. The presence of antibodies among HCWs may help in their placement and triage. HCWs may be advised to report early in case of any symptoms of COVID-19. Preventive measures may be targeted based on the location, with particular emphasis on ancillary workers and nurses.

Intra-abdominal Inflammatory Myofibroblastic Tumour (IMFT)-Uncommon Entity.

IMFT (inflammatory myofibroblastic tumour) is an uncommon tumour predominantly affecting the lungs and mediastinum. Most of the published literature supports that it affects children and young individuals. IMFT involving the gastrointestinal tract is rare. We report a case of multifocal IMFT affecting the GI tract which was managed with gross total excision followed by chemotherapy. Surgical resection remains the treatment of choice. The role of chemotherapy and radiation therapy remains limited. The aetiology of these tumours remains unclear and is mostly ALK-positive that could be targeted. Local recurrences are common and hence require close follow-up. The risk of recurrences and metastasis is increased in cases with TP53 positivity, aneuploidy and recurrent lesions.

Enhanced Spacer Length between Mannose Mimicking Shikimoyl and Quinoyl Headgroups and Hydrophobic Region of Cationic Amphiphile Increases Efficiency of Dendritic Cell Based DNA Vaccination: A Structure-Activity Investigation.

In the field of dendritic cell based genetic immunization, previously we showed that liposomes of cationic amphiphiles containing mannose-mimicking shikimoyl headgroup are promising DNA vaccine carriers for dendritic cell (DC) transfection. The present structure-activity study reports on the influence of spacer length (between mannose-mimicking headgroups and quaternary nitrogen centers) in modulating the DC-transfection efficiencies. Further, we report on the anti-melanoma immune response inducing properties of the promising cationic amphiphiles in syngeneic C57BL/6J mice under prophylactic settings.
