Postpartum Acute Kidney Injury: Experience of a Tertiary Care Center.

Pregnancy-related-acute kidney injury (PR-AKI) had decreased from 40% to 20% in 1960 to <10% in recent series, mostly due to meticulous antenatal management. Postpartum-AKI (PP-AKI) resulting from late obstetric complications has become more apparent after improvement in antenatal care and legalization of medical termination of pregnancy. Women with renal injury in peripartum period admitted to our hospital over a period of 2 years (April 2013 to May 2015) were studied. Of 713 patients of AKI admitted, 61 had PR-AKI with an incidence of 4.27%. Out of the 61 patients, 28 had PP-AKI with an incidence of 1.96%. The mean age of patients with PP-AKI was 26.10 ± 4.3 years. Sepsis was the most common cause accounting for 11 (39.28%) cases followed by postpartum hemorrhage (PPH) in 7 (25%) cases. Renal biopsy was done in nine patients, out of whom four were having cortical necrosis. Patients having diffuse cortical necrosis remained dialysis-dependent. High contribution of sepsis and PPH to PP-AKI in our setting makes it an ideal target for rectification. Protocolized peripartum monitoring and standard clinical practices of asepsis will go long way in decreasing the incidence of PP-AKI and maternal morbidity in our valley.

Hookah smoking, nass chewing, and oesophageal squamous cell carcinoma in Kashmir, India.

BACKGROUND: Although cigarette smoking is an established risk factor for oesophageal squamous cell carcinoma (ESCC), there is little information about the association between other smoking and smokeless tobacco products, including hookah and nass, and ESCC risk. We conducted a case-control study in Kashmir Valley, India, where hookah smoking, nass chewing, and ESCC are common, to investigate the association of hookah smoking, nass use, and several other habits with ESCC. METHODS: We recruited 702 histologically confirmed ESCC cases and 1663 hospital-based controls, individually matched to the cases for age, sex, and district of residence from September 2008 to January 2012. Conditional logistic regression models were used to calculate odds ratios (ORs) and 95% confidence intervals (95% CIs). RESULTS: Ever-hookah smoking (OR=1.85; 95% CI, 1.41-2.44) and nass chewing (OR=2.88; 95% CI, 2.06-4.04) were associated with ESCC risk. These associations were consistent across different measures of use, including intensity, duration, and cumulative amount of use, and after excluding ever users of the other product and cigarette smokers. Our results also suggest an increased risk of ESCC associated with ever-gutka chewing and -bidi smoking. However, the latter associations were based on small number of participants. CONCLUSION: This study shows that hookah and nass use are associated with ESCC risk. As prevalence of hookah use seems to be increasing among young people worldwide, these results may have relevance not only for the regions in which hookah use has been a traditional habit, but also for other regions, including western countries.

Sudden retinal vein thrombosis in a patient with nephrotic syndrome.

The authors report a sudden painless blindness in a 42-year-old male with membranous nephropathy of idiopathic origin. He was admitted with a history of decreased urine output and painful abdomen of a 3-day duration in the Department of Nephrology, Sheri Kashmir Institute of Medical Sciences, Srinagar, Kashmir - a tertiary care centre in the state of Jammu and Kashmir, India. On evaluation, he was found to have renal vein thrombosis. On day 3 of admission, he suddenly developed progressive painless blindness. Indirect ophthalmoscopic examination showed retinal vein thrombosis. Patient's clinical condition deteriorated due to his underlying condition and he succumbed to his illness. Renal vein thrombosis as a complication of nephrotic syndrome is well known. To the best of our knowledge, this is the first case of retinal vein thrombosis in the course of nephrotic syndrome.

Collapsing glomerulopathy in an HIV-positive patient in a low-incidence belt.

Human immunodeficiency virus (HIV) involves glomerular, tubulointerstitial, and vascular compartments of the kidney. The most common glomerular lesion is HIV-associated focal segmental glomerulosclerosis (FSGS) and related mesangiopathies collectively termed HIV-associated nephropathy (HIVAN). A variety of immune-complex mediated glomerular diseases such as membranoproliferative glomerulonephritis (MPGN), IgA nephropathy, and lupus-like glomerulonephritis also occur. HIVAN is restricted to patients presenting with proteinuria and progressive reduction of renal function and with distinctive but not pathognomonic pathology (FSGS often coexisting with glomerular collapse and tubular microcystic dilatations). The worldwide incidence of collapsing glomerulopathy (CG) in HIV-positive patients is high in Americans. But in India and other Asian countries, other forms of kidney diseases are more commonly seen. We report the first case of CG in the state of Jammu and Kashmir which also happens to be a very low incidence belt for HIV.

Approach to urinary tract infections.

Urinary tract infection (UTI) is the most common infection experienced by humans after respiratory and gastro-intestinal infections, and also the most common cause of both community-acquired and nosocomial infections for patients admitted to hospitals. For better management and prognosis, it is mandatory to know the possible site of infection, whether the infection is uncomplicated or complicated, re-infection or relapse, or treatment failure and its pathogenesis and risk factors. Asymptomatic bacteriuria is common in certain age groups and has different connotations. It needs to be treated and completely cured in pregnant women and preschool children. Reflux nephropathy in children could result in chronic kidney disease; otherwise, urinary tract infections do not play a major role in the pathogenesis of end-stage renal disease. Symptomatic urinary tract infections occur most commonly in women of child-bearing age. Cystitis predominates, but needs to be distinguished from acute urethral syndrome that affects both sexes and has a different management plan than UTIs. The prostatitis symptoms are much more common than bacterial prostatic infections. The treatment needs to be prolonged in bacterial prostatitis and as cure rates are not very high and relapses are common, the classification of prostatitis needs to be understood. The consensus conference convened by National Institute of Health added two more groups of patients, namely, chronic prostatitis/chronic pelvic pain syndrome and asymptomatic inflammatory prostatitis, in addition to acute and chronic bacterial prostatitis. Although white blood cells in urine signify inflammation, they do not always signify UTI. Quantitative cultures of urine provide definitive evidence of UTI. Imaging studies should be done 3-6 weeks after cure of acute infection to identify abnormalities predisposing to infection or renal damage or which may affect management. Treatment of cystitis in women should be a three-day course and if symptoms are prolonged, then a seven day course of antibiotics should be given. Selected group of patients benefits from low-dose prophylactic therapy. Upper urinary tract infection may need in-patient treatment. Treatment of acute prostatitis is 30-day therapy of appropriate antibiotics and for chronic bacterial prostatitis a low dose therapy for 6-12 months may be required. It should be noted that no attempt should be made to eradicate infection unless foreign bodies such as stones and catheters are removed and correctable urological abnormalities are taken care of. Treatment under such circumstances can result only in the emergence of resistant organisms and complicate therapy further.

Arsenic induces oxidative stress, sphingolipidosis, depletes proteins and some antioxidants in various regions of rat brain.

OBJECTIVES: To seek an interrelationship, if any, between oxidant stress and neurochemical changes in various rat brain regions after arsenic exposure. MATERIALS AND METHODS: This study was carried out at the Department of Biochemistry, Al Arab Medical University, Benghazi, Libya. Seventy five male Spraque-Dawley rats were divided into three groups: CONTROL GROUP: Rats were administered 2 ml of normal saline solution/kg body weight (b.wt.) daily for 20 days by intraperitoneal (i.p.) route. ARSENIC-TREATED GROUP: Rats received elemental arsenic (as sodium arsenate) 2.0 mg/kg b.wt. daily for 20 days by i.p. route. RECOVERY GROUP: Rats received 2.0 mg/kg b.wt. elemental arsenic daily for 20 days by i.p. route and were allowed to recover for 20 days. Rats were sacrificed and brains were dissected into cerebral cortex, corpus striatum, cerebellum and brain stem. Tissue homogenized in respective mediums. And were analyzed for lipid classes, oxidative stress, concentration of proteins, glutathione and ascorbic acid by utilizing standard colorimetric procedures. RESULTS: Arsenic exposure increased the oxidant stress because lipid peroxidation was enhanced. And decreased the contents of lipid classes, proteins, glutathione and the ascorbic acid in various rat brain regions. However, thins-layer chromatography exhibited regional variations in phospholipids classes. CONCLUSION: These results suggested that arsenic-initiated oxidant stress by increasing lipid peroxidation. The losses of lipid classes, ascorbic acid and glutathione may be attributed to peroxidative damage and binding of arsenic with sulfhydryl groups of enzymes. Recovery of animals showed reversibility in most of studied parameters, but gangliosides and cerebrosides over shooted. And speculated "Sphingolipidosis". It is then likely that repeated exposures of humans to arsenic may result in hampering of cell signalling, apoptosis and mutagenesis.

Etiological profile of nephrotic syndrome in Kashmir.

Our study aimed to obtain a comprehensive insight into the etiology of nephrotic syndrome in our patient population. We analyzed medical records of 290 patients with diagnosis of nephrotic syndrome as defined by International Study of Kidney Disease in Children (ISKDC), between January 1987 and December 2000, at the Sher-I-Kashmir Institute of Medical Sciences, Soura, Srinagar. Primary glomerular disease was found to be the most prevalent, accounting for 91.73% of all glomerular diseases. Among primary glomerular diseases, minimal change disease (MCD) was the most common histological lesion (43.79%). Most patients presented within 3 months duration (61.4%) and the most common symptom was puffiness of face (98.45%) followed by pedal edema (91%). Focal segmental glomerulosclerosis (FSGS) was the second most common lesion (16.89%) followed by membranous glomerulonephritis (GN) (13.4%) and membranoproliferative GN (11.72%). Amongst secondary glomerular diseases, diabetes mellitus was the most prevalent (4.48%), followed by lupus nephritis (3.1%). In conclusion, primary glomerular diseases constituted the most common group encountered and the prevalence of MCD was quite high with males, children and young adults. FSGS was associated with a high prevalence of end-stage renal disease (ESRD; 26.53%), hypertension (71.42%) and hematuria (81.63%).

Vitamin D intoxication presenting as acute renal failure.

A 70 year-old male presented with acute renal failure and mental obtundation. On examination, he was found to have hypercalcemia and on further questioning, it was found that it was secondary to injections of a slow-release vitamin D preparation. Although total body exposure is sufficient for vitamin D synthesis, increased vitamin D deficiency secondary to poor exposure to sunlight is observed in some parts of the world. We report here a case of vitamin D intoxication from the Kashmir valley where vitamin D deficiency is 100% in the general population that is confined indoors.

Further observations on acute renal failure following physical torture.

Thirty-four males aged 16-40 (mean 25) years in the period from August 1991 to February 1993 presented in acute renal failure (ARF), 3-14 (mean 5) days after they had been apprehended and allegedly tortured in Police interrogation centres in Kashmir. All were beaten involving muscles of the body, in addition 13 were beaten on soles, 11 were trampled over and 10 had received repeated electric shocks. Patients were studied in three groups: group I, those with evidence of only myoglobinuria (n = 21); group II, those with both myoglobinuria and haemoglobinuria (n = 10); and group III, those with evidence of only haemoglobinuria (n = 3). All had varying degrees of ecchymotic patches on the body and patients in groups II and III were beaten on soles had ecchymosis of soles. Hypertension was present in 11 and pulmonary oedema in five. Mean haemoglobin, BUN and serum creatinine were not significantly different in the three groups. Creatine phosphokinase in groups I, II and III were 985-7516 (1358 +/- 368), 917-5277 (1431 +/- 188), and 517-816 (772 +/- 69) and lactic dehydrogenase levels were 757-3727 (2191 +/- 56), 592-3454 (1923 +/- 164), and 446-958 (632 +/- 115) respectively. All the cases had metabolic acidosis, 20 had hyperkalaemia. Plasma haemoglobin was 11-48 (mean 26) mg/dl in group II and 26-56 (mean 35) mg/dl in group III. Urine test for haemoglobin was positive in seven cases in group II and two cases in group III. Pigment casts were present in 10, eight and two cases in groups I, II, and III respectively. Only those who were beaten on soles had evidence of haemoglobinuria.(ABSTRACT TRUNCATED AT 250 WORDS)

Acute renal failure following physical torture.

Ten cases of acute renal failure (ARF) were seen in the period from July 1990 to August 1991 in the Nephrology Department of the SIMS Hospital, Srinagar. All were males in the age group of 18-28 years and in apparent good health when apprehended by the police. There was alleged history of physical torture of different types. All had been beaten on the buttocks, back and limbs; in addition, 2 cases had been given repeated electric shocks and 1 case put to 'sit-and-stand' exercise for about 3 h. The interval between the first day of torture till they came to our observation varied from 4 to 11 days. The main clinical features at the time of presentation were generalized aches and weakness (10), oligoanuria (9), vomiting (8), hypertension (6), acidosis (10), facial puffiness and pedal edema (6), fever and shivering (3), pulmonary edema (2), stupor (4), and hyperkalemia (5). All the cases had an established ARF (serum creatinine 668-1,997 mumol/l and serum urea 21.8-71.8 mmol/l) when first seen. Muscle enzymes, creatine phosphokinase, lactic dehydrogenase and serum glutamic oxaloacetic transaminase were all significantly raised indicating rhabdomyolysis. All showed evidence of myoglobin casts in urine. Nine had oliguric and 1 had nonoliguric ARF. All except the 1 case with nonoliguric ARF were managed with peritoneal dialysis and/or hemodialysis. All recovered. Early recognition of ARF is important since the main attention in such cases is directed towards the surgical aspect.
