Four patients of pure gouty nephropathy are presented. Gout was of over five years duration and asymptomatic nephropathy manifested as non-oliguric acute renal failure. Diseases commonly associated with it like uric acid stones, urinary tract infections, hypertension, diabetes mellitus, hyperlipidemid, obesity and nephrosclerosis were absent. Reduction in serum uric acid level resulted in prompt improvement in renal functions. Early detection and control of hyperuricemia may help in restoration of renal functions.

Six patients who had a total hip replacement, as well as a trochanteric osteotomy, while they were in the lateral decubitus position had complications involving the contralateral side. The complications included transient paresthesias, massive swelling of the thigh with myonecrosis, acute renal failure secondary to myoglobinuria, and arterial insufficiency that resulted in a below-the-knee amputation. In order to elucidate the causes of the complications, the external pressure of the contralateral femoral triangle and the blood flow to the contralateral foot were monitored intraoperatively in seventeen patients. The results supported the postulate that pressure at the groin is increased intraoperatively and that this can cause vascular compromise. Other proposed causes of the complications were pre-existing vascular disease, obesity, the lateral decubitus position of the patient on the operating table, and the use of hypotensive anesthesia. We found several techniques that may minimize complications in the contralateral limb during operations on the hip.

An autopsy case of 23-years-old man with Prader-Labhart-Willi syndrome (P-L-W syndrome), who had died by acute renal failure due to burn injury, was reported. P-L-W syndrome was constituted by hypotonia, hypogonadism, hypomentia, obesity and other minor anomalies, however, CNS anomaly had not been reported. The patient sat at 3 years of age, walked at 4 years old, began to utter single words at 3-4 years, and he began to obese at 4 years of age. He fulfilled the condition of P-L-W syndrome mentioned above. On his age 15, laboratory findings on admission revealed remarkable diabetic pattern by oral glucose tolerance test and intelligence quotient was 28, and the other laboratory findings were within normal limit. During his clinical history, complications of diabetes mellitus, such as diabetic retinopathy and neuropathy, were aggrevated, and upstanding and gait were impossible at 20 years of age. On his age 23, he suffered from burn injury at left lower extremity and he fell in acute renal insufficiency. Five autopsy cases of P-L-W syndrome have been reported so far, however, CNS anomaly has not been observed. Following anomalies in our case was recognized, such as shortness of the frontal lobe, partial micropolygyria of the dentate nucleus, heterotopia of the inferior olivary nucleus, ectopia of Purkinje cell in the molecular layer, heterotopia of middle sized neuron in the deep white matter of the cerebellum and large number of residual nerve cells in the cerebral subcortical white matter.(ABSTRACT TRUNCATED AT 250 WORDS)

Applied anatomy and physiology of the kidney are briefly reviewed. This includes an account of renal blood flow, glomerular filtration rate, juxtaglomerular apparatus, renal autoregulation and intra-renal blood flow distribution, tubular transport mechanisms, solute handling in proximal tubule, function of loop of Henle and distal tubule system. This section concludes with a summary of changes in tubule fluid along the length of the nephron. Acute effects of anaesthesia are reviewed in detail. Indirect effects include those on circulatory and sympathetic nervous systems, autoregulation, endocrine systems such as those involving anti-diuretic hormone, adrenaline and noradrenaline, renin-angiotensin and aldosterone. Direct effects of anaesthesia on renal function have now been confirmed both in vitro and in vivo. Delayed direct nephrotoxicity of anaesthetics relates predominantly to methoxyflurane (MOF) and its metabolism to inorganic fluoride. Other factors are MOF dose, genetics, age, enzyme induction, obesity, other nephrotoxic drugs. Clinical implications are presented. Enflurane nephrotoxicity is rare but aetiologic factors are similar to the foregoing. Isoflurane and halothane are not nephrotoxic. A consideration of the influence of anaesthetic management on the incidence and severity of postoperative acute renal failure concludes the review.

Using compartmental analysis techniques, we modeled the biodistribution of Tc-99m(Sn)methylene diphosphonate in humans on a computer, and by selectively perturbing appropriate rate constants, we simulated changes in contrast between bone and soft tissue in a number of systemic disorders. The model predicts low contrast in patients with moderate to marked edema, obesity, congestive heart failure or decreased cardiac output states and high contrast with as little as 25% increase in bone avidity for the tracer. In acute renal failure without fluid-volume imbalance, image contrast should be normal. The model predicts greater contrast shortly after injection in patients with increased cardiac output, skeletal blood flow, or bone avidity; images made at these times would be indistinguishable. These simulations are in keeping with reports in the literature of bone images and bone-to-soft tissue ratios in many of these conditions, suggesting that modeling studies could play an important role image interpretation.

In a university-affiliated community hospital, medical records of 58 patients on whom the intact parathyroid hormone immunoassay (I-PTH) and 29 patients on whom both the carboxyl terminal PTH(C-PTH) and I-PTH ordered by physicians were reviewed to determine the reasons for requesting these tests. Reasons for ordering the PTH tests include (1) the evaluation of hypercalcemic patients (25/58 I-PTH); (2) the evaluation of hypocalcemic patients (2/58 I-PTH); (3) to rule out primary hyperparathyroidism in normocalcemic stone formers (4/58 I-PTH, 4/29 C-PTH) and in those with abnormal skeletal x-ray (3/48 I-PTH 1/29 C-PTH); (4) to follow patients with chronic renal failure on dialysis (11/58 I-PTH, 9/29 C-PTH); (5) to rule out ectopic hyperparathyroidism in patients with cancer (2/58 I-PTH, 3/29 C-PTH); (6) to satisfy physicians' intellectual curiosity of patients with diabetes mellitus (3/58 I-PTH, 3/29 C-PTH) and obesity (5/58 I-PTH; 6/29 C-PTH); (7) to evaluate acute renal failure (1/29 C-PTH). In 3/58 patients on whom I-PTH tests were ordered, reason(s) could not be determined. The C-PTH was elevated in 9/9 patients with chronic renal failure, 4/6 obese patients, 2/3 patients with cancer, 1/3 diabetic patients, 1/4 stone formers, 2/2 patients with primary hyperparathyroidism. Patients with chronic renal failure had the highest C-PTH. Based on well established indications for ordering the PTH immunoassays, 25 out of 58 (43%) of I-PTH and 9 out of 29 (31%) of C-PTH ordered are inappropriate.

With the awareness of health problems related to obesity, weight reducing diets have become very popular. However, if these meal supplements are not taken as recommended, they can cause considerable harm in high risk individuals. We report a case of a young obese man who developed diabetic ketoacidosis (DKA) followed by rhabdomyolysis and acute renal failure (ARF) after excessive intake of a high carbohydrate containing weight-reducing meal. DKA associated with excessive intake of weight reducing diets has not been reported previously. In people with obesity and insulin resistance improper use of these supplements can cause severe metabolic complications.

Although there are many potential changes of pharmacokinetic parameters in patients with thermal injury, obesity or septicemia, data about the actual effect on pharmacokinetics and clinical efficacy of fluconazole are very limited. As current dosing recommendations are derived from healthy subjects and patients with normal weight, these recommendations may be inaccurate when applied to the patient populations mentioned above. Pharmacokinetic data of 14 patients with thermal injury were reviewed and revealed a shorter half life and more rapid clearance of fluconazole. In a subgroup of five patients, distribution volume was up to 2 times larger as usual with no relationship to creatinine clearance and degree of burns. In one extremely obese patient treated with fluconazole 1200 mg/day, the corresponding mean steady-state plasma concentration and AUC were decreased with an increase of fluconazole clearance possibly due to a larger volume of distribution. In patients with septicemia, fluconazole plasma levels appear to be highly variable. As a considerable number of these patients develops acute renal failure, renal replacement therapy may be indicated which may require substantial dosage modifications of fluconazole.

Suction lipoplasty is practiced popularly for obesity control and cosmetic purposes and severe complications are rare. We report the first documented case of acute renal failure, with anuric period, that developed after excessive bleeding following cosmetic liposuction. The use of homocoagulase and the presence of rhabdomyolysis might have contributed to the acute renal failure and disseminated intravascular coagulation observed in this case.

The long-term outcome of 20 preterm infants with extremely low birth weight and acute renal failure in the neonatal period was studied retrospectively over an 18-year period. Those with progressive renal disease are compared with those with normal renal function. Current mean age is 7.5+/-4.6 years (range 3.2-18.5 years). Nine patients showed deterioration in renal function (low GFR group). Increasing proteinuria, as determined by random urine protein/creatinine ratio (Up/c), correlated with deterioration in renal function ( r=0.8, P<0.0001). Prominent risk factors for progression were Up/c >0.6 at 1 year of age [100% sensitivity, 75% positive predictive value (PPV), P<0.01], serum creatinine >0.6 mg/dl at 1 year of age (75% sensitivity, 80% PPV, P<0.01), and a tendency to obesity with body mass index >85th percentile (89% sensitivity, PPV 67%, P=0.03). Loss of renal mass and nephrocalcinosis were not prognostic indicators. This report begins to identify important clinical parameters that should lead to closer surveillance and potential treatment interventions for preservation of renal function in a growing population of surviving low birth weight individuals.
