Small intestinal deficit in pellagra

Twenty-four persons with pellagra were the subjects of absorption testing. Fourteen (58.3%) showed evidence of defective absorption of two or three absorption tests and eight showed (33.3%) abnormality of only one of the tests of absorption. Only two cases (8.3%) were found to be having completely normal absorptive status of the small bowel. Six of these fourteen (42.8%) cases recovered completely or partially on treatment with nicotinic acid. The etiopathogenesis of malabsorption in pellagra is discussed. Patients of both primary as well as secondary pellagra showed similar derangement of small intestinal functions

Mental disorders in primary health care: a study of their frequency and diagnosis in four developing countries

1624 patients who were attending primary health facilities in 4 developing countries were examined to determine how many were suffering from mental disorder. Using stringent criteria to establish the presence of psychiatric morbidity, 225 cases were found, indicating an overall frequency of 13·9 %. The great majority of cases were suffering from neurotic illnesses and for most the presenting complaint was of a physical symptom, such as headache, abdominal pain, cough or weakness. The health workers following their normal procedure correctly detected one third of the psychiatric case

Primary gastric tuberculosis – report of 5 cases

BACKGROUND: Gastric tuberculosis is rare, and usually associated with pulmonary tuberculosis or an immunodeficient state. Here, we report five cases of gastric tuberculosis in immunocompetent patients without evidence of pulmonary involvement. CASE PRESENTATION: Three patients presented with gastric outlet obstruction that required surgery to relieve the obstruction as well as to confirm the diagnosis. The remaining two had involvement of gastroesophageal junction. All of them responded well to standard antitubercular treatment. CONCLUSION: Though gastric tuberculosis is rare, it should be considered a possibility when patients present with gastric outlet obstruction or with endoscopic evidence of diffuse chronic inflammatory activity, particularly in areas endemic for tuberculosis

Baroreflex sensitivity is impaired in survivors of mild COVID-19 at 3-6 months of clinical recovery; association with carotid artery stiffness

The association between the stiffening of barosensitive regions of central arteries and the derangements in baroreflex functions remains unexplored in COVID-19 survivors. Fifty-seven survivors of mild COVID-19 (defined as presence of upper respiratory tract symptoms and/or fever without shortness of breath or hypoxia; SpO2 > 93%), with an age range of 22-66 years (27 females) participated at 3-6 months of recovering from the acute phase of RT-PCR positive COVID-19. Healthy volunteers whose baroreflex sensitivity (BRS) and arterial stiffness data were acquired prior to the onset of the pandemic constituted the control group. BRS was found to be significantly lower in the COVID survivor group for the systolic blood pressure-based sequences (BRS SBP ) [9.78 (7.16-17.74) ms/mmHg vs 16.5 (11.25-23.78) ms/mmHg; p = 0.0253]. The COVID survivor group showed significantly higher carotid β stiffness index [7.16 (5.75-8.18) vs 5.64 (4.34-6.96); (p = 0.0004)], and pulse wave velocity β (PWVβ ) [5.67 (4.96-6.32) m/s vs 5.12 (4.37-5.41) m/s; p = 0.0002]. BRS quantified by both the sequence and spectral methods showed an inverse correlation with PWVβ in the male survivors. Impairment of BRS in the male survivors of mild COVID-19 at 3-6 months of clinical recovery shows association with carotid artery stiffness
