Recurrent Hypokalemia leading to Flaccid Quadriparesis: A Renal or Connective Tissue Disorder.

Hypokalemic periodic paralysis (hypoKPP) is a clinical entity characterized by recurrent skeletal muscle paralysis due to a decrease in serum potassium levels; hypoKPP can have either a primary (familial) or a secondary cause. One of the secondary causes of hypoKPP is distal renal tubular acidosis (dRTA). Distal renal tubular acidosis (dRTA) is diagnosed when the urinary pH is greater than 5.3 and in the presence of hyperchloremic metabolic acidosis and hypokalemia, with one of the causes being primary Sjögren's syndrome (pSS). PSS can have both glandular and extra glandular manifestations, with dryness of the eyes and mouth being the most common presenting symptoms. DRTA arising from pSS is very unusual, occurring in fewer than 2% of the cases of Sjogren's syndrome (SS). Here, we report on a case of recurrent flaccid quadriparesis that appears to have been caused by distal RTA, resulting in hypokalemia; upon further investigation and clinical evaluation, the patient was diagnosed with pSS.

Post Stroke Psychosis Following Lesions in Basal Ganglion.

Stroke is the second most common cause of death and fourth leading cause of disability worldwide. Post stroke behavioural manifestations are often not recognized, undiagnosed and hence remain untreated. They may even suffer from misdiagnosis of functional disorders before coming at conclusion of organic pathology. Early diagnosis and prompt treatment helps in lowering the overall morbidity related to stroke and improves quality of life of these patients with rare manifestations. Here, we report two cases of elderly female patients presenting with delusions and hallucinations subsequent to stroke, with lesions in basal ganglia detected on neuro-imaging.

Acute viral hepatitis E presenting with haemolytic anaemia and acute renal failure in a patient with glucose-6-phosphate dehydrogenase deficiency.

The association of acute hepatitis E viral (HEV) infection with glucose-6-phosphate dehydrogenase (G6PD) deficiency leading to extensive intravascular haemolysis is a very rare clinical entity. Here we discuss such a patient, who presented with acute HEV illness, developed severe intravascular haemolysis and unusually high levels of bilirubin, complicated by acute renal failure (ARF), and was later on found to have a deficiency of G6PD. The patient recovered completely with haemodialysis and supportive management.

Serum organochlorine pesticide levels in patients with metabolic syndrome.

INTRODUCTION: Organochlorine pesticides (OCPs) are endocrinal disruptors that tend to accumulate in adipose tissue and have been found to be associated with Metabolic Syndrome (MS). AIM AND OBJECTIVES: 1. To measure serum OCP levels in patients of MS and control subjects, 2. To identify differences, if any, in serum OCP levels, in patients with MS and control subjects. MATERIALS AND METHODS: Cross-sectional study was conducted in the Departments of Medicine and Biochemistry at University College of Medical Sciences (UCMS) and Guru Teg Bahadur Hospital (GTBH), Delhi. Nine OCPs [α-HCH (Hexachlorocyclohexane), ß-HCH, g-HCH, α-endosulfan, ß-endosulfan, aldrin, dieldrin, p, p'-DDT (Dichloro-diphenyl-trichloro-ethane), and p, p'-DDE (Dichloro-diphenyl-dichloro-ethylene)] were studied. Fifty subjects ≥18 years with MS (study group) and 50 age and sex-matched controls were included in the study. EXCLUSION CRITERIA: (1) Persons having chronic occupational exposure to OCPs such as workers of pesticide factories, (2) Recent exposure to OCPs within 4 weeks. RESULTS: Levels of all nine OCPs were higher in cases as compared to controls. However, only the mean value of ß-HCH in cases (8.40 ± 8.64 ng/ml) was significantly (P < 0.001) higher as compared to controls (2.58 ± 2.34 ng/ml). After adjustment of confounding factors like age, sex, smoking, alcohol, and body mass index (BMI), only ß-HCH and aldrin levels were positively and significantly associated with the risk of having MS. Adjusted Odds Ratio (OR) was 1.34 [CI = 1.14-1.57 (P < 0.001)] and 1.23 [CI = 1.01-1.50 (P = 0.045)], respectively. CONCLUSION: There was a significant association of ß- HCH and aldrin levels with MS.

Monoclonal gammopathy associated with visceral leishmaniasis.

Monoclonal gammopathy can accompany diverse conditions and is usually benign. It should be distinguished from monoclonal gammopathy of undetermined significance (MGUS) which can rarely turn malignant. Visceral leishmaniasis has only rarely been associated with monoclonal gammopathy. We describe the case of a 55-year-old male who had monoclonal gammopathy associated with visceral leishmanisais, which reversed with stibogluconate therapy.

Concurrent reactive arthritis and myelitis - a case report.

Reactive arthritis is a post infectious multisystem illness which usually occurs after episodes of diarrhoea or urinary tract infections. It can cause many manifestations other than the musculoskeletal system including skin, urogenital system and eyes. However the central nervous system is only occasionally involved. We discuss the case of a 32 year old male who presented with myelitis in association with reactive arthritis.

Acute hepatic failure due to dengue: A case report.

Dengue is an arboviral disease endemic in many parts of the world. Although it is known to cause hepatic involvement commonly, it only occasionally results in acute hepatic failure. We present the case of a young male who developed acute hepatic failure due to dengue. The differentials and the management is discussed.

Monitoring oxidative stress across worsening Child Pugh class of cirrhosis.

CONTEXT: Oxidative stress has been increasingly implicated in the pathogenesis and progression of cirrhosis. AIMS: We studied oxidative stress in patients with cirrhosis by measuring markers reflecting pro-oxidant (serum malondialdehyde-MDA) and antioxidant factors (RBC catalase-CAT, superoxide dismutase-SOD and blood reduced glutathione-GSH) factors. The level of oxidative stress was also assessed with respect to functional compromise of liver, as determined by Child Turcotte Pugh (CTP) scoring. DESIGN: Case-controlled retrospective study. MATERIALS AND METHODS: Twenty-three patients of cirrhosis along with 23 age and sex matched healthy controls were studied. Exclusion criteria were concurrent use of anti-oxidant drugs; co-existing diseases like DM, CKD; alcohol use, gastrointestinal bleed or blood transfusion within previous 2 weeks. Besides routine investigations, MDA, CAT, SOD and GSH levels were measured and compared with controls. STATISTICAL ANALYSIS: Continuous variables were recorded as mean +/- SD; ANOVA-f test, followed by Tukey's test, was used to evaluate the significance of difference (P < 0.05) among groups. RESULTS: Mean age of patients was 41.04 +/- 12.3 yrs. Patients showed a significant increase in MDA {control 3.31 +/- 0.25 (95% CI 3.21-3.41), Child B 6.30 +/- 0.4 (95% CI 6.03-6.53), Child C 8.05 +/- 0.66 (95% CI 7.29-8.81) nmol/l} and a significant decrease in levels of SOD {control 845.13 +/- 36.44 (95% CI 829.92-860.34), Child B 582.91 +/- 42.12 (95% CI 557.45-608.32), Child C 489.5 +/- 17.66 (95% CI 479.3-499.7) U/gm Hb}, CAT {controls 2.54 +/- 0.22 (95% CI 2.45-2.63), Child B 1.93 +/- 0.23 (95% CI 1.72-2.14), Child C 1.46 +/- 0.10 (95% CI 1.40-1.52) U/ gm Hb} and GSH {controls 6.52 +/- 0.25 (95% CI 6.42-6.52), Child B 3.85 +/- 0.18 (95%CI 3.74-3.96), Child C 2.99 +/- 0.30 (95% CI 2.82-3.16) mmol/ gm Hb}. CONCLUSIONS: Oxidative stress is associated with the development and progression of cirrhosis.
