Extramedullary haematopoiesis in a patient with myelofibrosis.

Megakaryocytes are large multilobulated precursor cells which usually reside within the bone marrow and give rise to platelets. There have been rare occurrences where they have been found in peripheral blood and extramedullary tissues in conditions where the underlying mechanisms of the bone marrow have been affected. This case report discusses an unusual presentation of a man with myelofibrosis who was found to have megakaryocytes in his ascitic fluid. We have highlighted the images showing utility of combination of traditional staining methods and immunohistochemistry in combating this diagnostic dilemma.

Impact of Self-Help Groups among Persons With Disabilities in Rural Karnataka - A Comparative, Cross-Sectional Study.

Background: The prime concern for an individual with disability is independence. Self-help groups (SHGs) provide opportunities for those with such needs. Objectives: The objectives of the study were (i) to assess the impact of SHGs on the livelihood, social inclusion, and community participation of those with disability and (ii) to evaluate the self-esteem and assess the role of such SHGs among those with disability. Materials and Methods: This was a community-based, cross-sectional study. An interview schedule captured responses to standardized questionnaires (community-based rehabilitation assessment tool, Rosenberg's self-esteem score, and Social Inclusion Scale). Responses were scored and compared among the two groups of those with disability (member or nonmember of SHGs). Results: The median scores for all our outcome variables were found to be more among those with disabilities enrolled in SHGs than those who were not with a significant association in the component of empowerment, sociocommunity participation, social inclusion, and self-esteem. Conclusion: SHGs improve social and community participation of individuals with disability. It empowers them to lead independent lives and also contributes to social inclusion.

Are blood groups related to the distribution and severity of COVID-19? A cross-sectional study in a tertiary care hospital in South India.

Background: Blood groups are inherited traits that affect the susceptibility/severity of a disease. A clear relationship between coronavirus disease 2019 (COVID-19) and ABO blood groups is yet to be established in the Indian population. This study aimed to demonstrate an association of the distribution and severity of COVID-19 with ABO blood groups. Methods: A cross-sectional study was conducted after obtaining ethics approval (IEC 207/20) among hospitalized patients using in-patient records and analyzed on SPSS-25. Chi-square tests were used for the analysis of categorical data and independent sample t-test/Mann-Whitney U tests were used for continuous data. Results: The B blood group had the highest prevalence among COVID-19-positive patients. The AB blood group was significantly associated with acute respiratory distress syndrome (ARDS) (p = 0.03), sepsis (p = 0.02), and septic shock (p = 0.02). The O blood group was associated with significantly lower rates of lymphopenia and leucocytosis. However, no significant clinical association was seen in the O blood group. Conclusion: This study has demonstrated that blood groups have a similar distribution among patients hospitalized with COVID-19 in the South Indian population. Additionally, it preludes to a possible association between the AB blood group and ARDS, sepsis, and septic shock. Further studies having a larger representation of AB blood groups, especially in patients hospitalized for critical COVID-19, with adjustment for possible covariates, are warranted to provide a reliable estimate of the risk in the South Indian population.

Reversal of portal gastropathy with partial internal biliary diversion in a case of progressive familial intrahepatic cholestasis.

Progressive intrahepatic cholestasis is a rare, genetic disorder causing bile acid secretion or transport defects. It can result in intrahepatic cholestasis that can progress to end-stage liver disease. Diagnosis is made using a combination of clinical and biochemical approaches. Genetic testing is currently the gold standard for investigation. We report a case of an 18-month-old male child with cholestatic pattern of jaundice from 16 months of life, which was associated with features suggestive of portal gastropathy. Detailed workup led to the diagnosis of progressive intrahepatic cholestasis (type 2). Early diagnosis prevented the need for liver transplant, and the child underwent surgical treatment with partial internal biliary diversion. Portal gastropathy and disease progression dramatically changed with corrective surgery. The patient was symptom-free at 10-week follow-up. Detecting this rare genetic disorder early has very good therapeutic implications from the patient's perspective and their morbidity and mortality profile; if untreated, it has a high propensity to progress to end-stage liver disease. The requirement of surgical interventions and liver transplantation is individualized on a case-to-case basis. An early diagnosis and initiation of treatment can prevent the need for a liver transplant as shown in the present case.

Pseudopapillary Tumor of the Pancreas: A Rare Cause of Extrahepatic Portal Hypertension.

A solid pseudopapillary tumor (SPT) of the pancreas is an uncommon neoplasm, characterized by a well-encapsulated mass, with low malignant potential. It occurs predominantly in young females. We present a case of SPT of the pancreas which presented with sinistral portal hypertension. Despite characteristic radiological findings due to its rarity, it may be missed to more common conditions like peptic ulcer disease. Delayed diagnosis can lead to complications like portal hypertension. To the best of our knowledge, in existing medical literature, SPT of the pancreas in males has rarely been described. In our case, we found that the tumor was causing extrahepatic portal hypertension which is also a very unique presentation of this tumor. Due to its vague clinical manifestations, definitive diagnosis is often a challenge hence requiring prompt investigations.

The utility of Vibratip in accurate identification of loss of protective sensation in the contralateral foot of patients admitted with a diabetic foot ulcer.

BACKGROUND AND AIMS: Diabetic foot ulcer (DFU) is a debilitating complication of type 2 DM. Complexity of foot examination often precludes proper clinical assessment of the foot during routine evaluation. We assessed the utility of novel device, vibratip, both singly and in combination with standard bedside tools for assessment of loss of protective sensation. METHODS: 75 patients admitted with DFU were included in the study. Clinical examination of the contralateral foot was done - temperature perception, vibration, pinprick sensation, Achilles tendon reflex and Neuropathy disability score were assessed. Testing using 10 g Monofilament, Vibratip and biothesiometer were also done. Considering the biothesiometer as the reference standard, three bedside tests (Vibratip, 10 g monofilament and 128 Hz tuning fork) were compared against it singly and in combinations. RESULTS: When compared against biothesiometer, vibratip performed significantly well with a positive predictive value of 90.3% and specificity of 84.2%. Sensitivity, however, was only 50%. On combining bedside tests, the best combination strategy was seen with vibratip and 10 g monofilament, which improved the sensitivity to 62.5%. Combining all three bedside tests further improved sensitivity to 64.3%. CONCLUSION: All the patients with an at-risk foot may not be identified with vibratip alone. Nevertheless, an abnormal result is almost always associated with loss of protective sensation, and such persons should be suitably educated. LIMITATIONS: Due to small size of the study population, it is not possible to generalize the findings to all patients with diabetes mellitus. A larger study would be required to provide more confirmatory findings.
