Eighty-six cats with non-dilated left ventricular myocardial hypertrophy were studied retrospectively. Cats were categorized by two-dimensional echocardiography as having symmetric ventricular hypertrophy (Type I), asymmetric with predominant septal thickening hypertrophy (Type II), and asymmetric hypertrophy with predominant free-wall thickening (Type III). The distribution of hypertrophy was judged subjectively and objectively. Subjective and objective results were similar (P = 0.03) although overlap existed between groups. Morphologic patterns (Types I, II, and III) were compared with breed, age, sex, heart rate, percent fractional shortening, left atrial size, serum creatinine concentration, and the presence (yes/no) of pleural effusion, pulmonary edema, pericardial effusion, heart murmur, dyspnea, thromboembolism, hyperthyroidism, and being alive at the time of study. Interventricular septal thickness, left ventricular free wall thickness, percent fractional shortening, and left atrial size additionally were compared to 3-month survival. Cats with Type III hypertrophy were more likely to experience thromboembolism than cats with Type II hypertrophy (P = 0.05) and cats with Type I hypertrophy were more likely to have heart murmurs than cats with Type III (P = 0.02). No other significant associations were found in comparison to pattern of hypertrophy. Both left atrial size and percent fractional shortening significantly correlated with 3-month survival (P < 0.001 for each). The degree of interventricular septal wall thickness was associated with 3-month survival (P = 0.02) when known hyperthyroid cats were excluded from the study group, while left ventricular free wall thickness consistently was not associated with survival.(ABSTRACT TRUNCATED AT 250 WORDS)

To evaluate the clinical characteristics of patients with anteroseptal myocardial infarction (MI) initially presenting with pulmonary edema, we analyzed 58 patients with anteroseptal MI who underwent emergency coronary arteriography that revealed single-vessel disease of the left anterior descending coronary artery. Of the 58 patients, pulmonary edema was observed in 24 patients (group A) and was absent in 34 patients (group B). Pulmonary capillary wedge pressure was significantly higher, and cardiac output was significantly lower in group A. The site of coronary stenosis, maximum serum creatinine kinase value, and wall motion point score did not differ between the two groups. However, the incidence of previous hypertension and posterior wall thickness > or = 11 mm was significantly higher in group A than in group B (p < 0.001 and p < 0.05, respectively). Thus, impaired left ventricular diastolic filling in the non-MI segments due to higher incidence of hypertension and left ventricular hypertrophy was considered to be the possible cause of pulmonary edema.

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.

Extravascular lung water (EVLW) measured by a double indicator dilution method using thermal-dye indicator was evaluated in 204 patients after cardiac surgery during last 7 years. The measurement of EVLW was done at 2, 4, 8, 24 and 48 hours after extracorporeal circulation (ECC), EVLW showed no significant change except transient decrease at 4 hours after ECC, average of that was 7.62 +/- 3.58 ml/kg, EVLW of group I (MVR) and group III (AVR + MVR) were significantly higher than those of group II (AVR), group IV (noncyanotic congenital heart disease) and group V (A-C bypass). EVLW of 7 patients with postoperative pulmonary edema was 14.47 +/- 4.44 ml/kg, and that was significantly higher than those of others (7.54 +/- 3.06 ml/kg). EVLW of the patients using bubble oxygenator (8.60 +/- 3.90 ml/kg) was significantly higher than those of membrane oxygenator (7.15 +/- 3.40 ml/kg). Postoperative EVLW correlated with mean pulmonary artery pressure (mPAP), mean left atrial pressure (LAP) and microvascular hydrostatic pressure (PMV), and showed inverse correlation with cardiac index (CI). But there was no correlation of EVLW with duration of ECC. In the preoperative parameter, EVLW correlated with age, mPAP, mean pulmonary wedge pressure (mPAWP), PMV, serum BUN and serum creatinine, and showed inverse correlation with CI, %VC, FEV%, PSP test and creatinine clearance. We concluded that the patients with mitral valve disease who have high mPAP and LAP, respiratory and renal dysfunction and old aged preoperatively showed upward trend of EVLW. In perioperative management, care must be taken in such patients and membrane oxygenator was thought useful for prevention of pulmonary edema.(ABSTRACT TRUNCATED AT 250 WORDS)

A 27-year-old Caucasian female, with a past history of recurrent spontaneous abortions, was admitted with pre-eclampsia at 26 weeks' gestation during her sixth pregnancy. She was previously known to have antiphospholipid antibodies since her fifth abortion, but had no clinical or serological evidence of systemic lupus erythematosus. A small-for-dates infant was delivered by emergency Caesarean section at 27 weeks for poor placental blood flow and fetal distress. She was transferred to the renal unit on the sixth post partum day with pulmonary edema, hypertension, disseminated intravascular coagulation and acute renal failure. Renal biopsy showed lesions compatible with thrombotic microangiopathy with diffuse glomerular necrosis. She was plasma exchanged and remained dialysis dependent for 7 months. Antiphospholipid antibodies were present in high titres and were the presumed cause of her acute renal failure. The patient now has stable renal function with a creatinine clearance of 30 ml/min for over two years. The late recovery of renal function is unique in the above circumstances.

Multiple organ dysfunction (MOD) is the leading cause of mortality in septic patients with circulatory shock. Recent evidence suggests that the overproduction of the cytokine, tumor necrosis factor-alpha(TNF), and oxygen free radical molecules may mediate the progression of sepsis to MOD and death. In this study, we have examined the ability of MDL 101,002, a free radical scavenger, to reduce organ dysfunction and cytokine secretion induced by lipopolysaccharide (LPS) administration in rats. Treatment with MDL 101,002(10-60 ng/kg, i.p.) 30 min prior to an LPS challenge resulted in a dose-dependent reduction in several markers indicative of organ dysfunction and mortality. MDL 101,002 markedly decreased LPS-induced liver and kidney damage as indicated by serum levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) or urea and creatinine, respectively. MDL 101,002 also prevented LPS-induced pulmonary edema, but did not prevent leukopenia and only partially reduced thrombocytopenia. Associated with these improvements in organ dysfunction and survival was a modest decrease in LPS-stimulated interleukin-1 alpha (IL-1 alpha) and interleukin-1 beta (IL-1 beta) secretion and a marked ( > 90%) inhibition of TNF secretion by MDL 101,002. The data are consistent with a role for oxygen free radicals in the development of endotoxin-induced organ dysfunction and shock and suggest that free radical scavengers could reduce the mortality consequent to sepsis by decreasing organ dysfunction, at least in part, through a reduction in free radical stimulated cytokine secretion.

Nephropathia epidemica (NE) is a hemorrhagic fever with renal syndrome (HFRS) normally taking a benign clinical course. The etiologic agent, Puumala hantavirus is genetically closely related to Sin Nombre virus, which causes a frequently lethal febrile syndrome with pulmonary involvement (hantavirus pulmonary syndrome, HPS). HPS is characterized by acute respiratory distress, non-cardiogenic pulmonary edema and severe and hypotension, but usually no significant renal involvement. Pulmonary involvement and respiratory symptoms also occur in NE. To understand the mechanisms of pulmonary involvement in NE, we studied the clinical records and chest X-rays of 125 hospital-treated acutely ill NE patients. Twenty-eight percent of the patients had disease-related changes in their chest radiographs. Pleural effusion and atelectasis were the most common X-ray findings, whereas frank pulmonary edema was rare. The patients with pathologic X-ray findings had a more marked hypoproteinemia (lowest measured serum protein concentration 54 +/- 1 g/l) than those with normal X-ray (62.1 +/- 0.9 g/l, p < 0.001) and leukocytosis (highest measured blood leukocyte count 14.1 +/- 0.9 x 10(9)/l vs. 10.6 +/- 0.6 x 10(9)/l, p < 0.001) and more severe renal insufficiency (highest measured serum creatinine 590 +/- 60 mumol/l vs. 356 +/- 29 mumol/l, p < 0.05). Hypoproteinemia best predicted the occurrence of abnormal chest X-ray findings in NE. This suggests, that capillary leakage and inflammation may play a role in the pathogenesis of NE lung involvement, similarly as in HPS. Differently from HPS, the fluid volume overload associated with renal insufficiency seemed to contribute strongly to the chest X-ray changes in NE.

A 56-year-old man who received a live-related renal transplant in 1988 was started in 1995 on the selective angiotensin II antagonist losartan (Dupont-Merke) to treat worsening hypertension. Two months later because of pulmonary oedema, loop diuretics were started. Within two weeks, serum creatinine had increased from 245 to 571 mumol/l, and the patient became oliguric. A systolic bruit was noted over the graft. Renal angiography showed a 90% stenosis of the transplant renal artery. Losartan was withdrawn, with prompt improvement in renal function. A successful percutaneous transluminal angioplasty performed a few days later resulted in further improvement in renal function accompanied by a significant diuresis.

This article aims at guidelines for evaluation of an accidentally detected increase of creatinine levels in serum and the decision if and when hospitalisation is mandatory. Hospitalisation is indicated when the general condition is poor and clinical signs of uremia like pericarditis, encephalitis, pulmonary edema with cliguria or anuria and severe hyperkalaemia or metabolic acidosis exist. In other cases an outpatient evaluation is possible yielding often information on preexisting risk factors, that may lead to functional renal failure, by history and clinical investigation. Furthermore assignment of the actual renal failure to a prerenal, renal or postrenal cause, usually by means of ultrasound and therapeutic consequences are demonstrated. A tabular overview on pathogenesis and gradation of various forms of acute renal failure and their identification by findings in urine sediments and/or chemical urine analysis is given.

We reviewed our experience of surgical and radiological intervention in 43 patients between 1987 and 1994 with angiographic renovascular disease. We retrospectively compared the effect of angioplasty with stenting versus reconstructive surgery on renal function and blood pressure in those patients with significant atherosclerotic renovascular stenosis. Twenty patients with moderate/non ostial stenosis (less than 60% stenosis) and two with fibromuscular displasia underwent renal angioplasty only. Indications for intervention were refractory hypertension (n = 20), flash pulmonary oedema (n = 8) and/or renal salvage (n = 31). All patients were hypertensive. Angioplasty with stenting was performed in ten patients, (2 female, 8 male), mean age 69 years, 9 with bilateral disease. Plasma creatinine was greater than 240 mumol/L in seven patients. A unilateral procedure was performed in 9 patients. Unilateral reconstructive surgery was performed in eleven patients (4 female, 7 male), mean age 63 years. Plasma creatinine was greater than 240 mumol/L in eight patients. Ten had bilateral disease. In the angioplasty/stenting group there were three technical failure. The mortality rates in the angioplasty/stenting group and surgical group were 10% and 27% respectively. Fifty-one and 165 patient months had elapsed in the stenting and surgical groups respectively. Blood pressure fell in each group, mean decrease in mean arterial pressure (MAP) 16 mmHg (p = 0.025) and 30 mmHg (p < 0.01) respectively. Improvement or stabilisation of renal function was achieved in 67% and 91% of cases respectively. Two surgical patients were able to discontinue haemodialysis. The two methods of treatment appear to be equally effective in lowering blood pressure. Reconstructive surgery offers greater improvement in renal function with the possibility of withdrawal of dialysis, at the expense of a higher mortality rate.
