Review of clinical and pathologic data from ten fatal cases of Rocky Mountain spotted fever (RMSF) revealed the importance of acute renal failure in the clinical course and of multifocal perivascular interstitial nephritis as the principal pathologic lesion. In nine cases, Rickettsia rickettsii were demonstrated by immunofluorescence in the areas of vasculitis. Evidence was lacking for the role of disseminated intravascular coagulation, glomerulonephritis, or myoglobinuria in the pathogenesis of acute renal failure in these cases. Rickettsia-induced vascular injury led to acute renal failure by several mechanisms. Hypovolemia early in the course resulted in reversible, prerenal azotemia. Transient hypotension in midcourse produced acute tubular necrosis. In fulminant cases, preterminal circulatory
collapse
was associated with coma and
oliguria
. The interstitial nephritis could not be demonstrated conclusively to contribute to the acute renal failure.

A 1-year study of the etiology of acute diarrhea complicated by severe (10%) dehydration, active bleeding, shock and cardiovascular
collapse
, pneumonia, acute renal failure, or seizures in infants under 18 months of age was performed in Cairo, Egypt. Of 145 infants, 19 (13%) died or left the hospital moribund; the remaining 126 patients were classified as having potentially fatal illness. A variety of enteropathogens were identified with approximately equal frequency in the fatal and nonfatal complicated cases as well as in 135 controls with severe uncomplicated diarrhea. The agents most frequently detected in infants with severe diarrhea in this population which were felt to be etiologically important were rotavirus (33%), heat-stable enterotoxin-producing Escherichia coli (20%), heat-labile enterotoxin-producing E. coli (11%), enteropathogenic E. coli (8%), and Salmonella spp. (5%). The high rate of occurrence of Giardia lamblia (35%) probably represented the high carriage rate of the protozoan in this population. Complicated (fatal and potentially fatal) cases differed from control cases in a number of ways: the onset of diarrhea was more sudden, the course was progressive and of greater initial intensity, vomiting occurred more frequently, the patients more often had visited another physician before coming to the hospital, the patients more often had respiratory symptoms and pulmonary abnormalities on auscultation, hypoactive bowel sounds and abdominal distention were more common, as was
oliguria
, and the patients showed lower mean body weights.

In a retrospective study we analyzed the clinical and blood chemical data of 12 patients with severe tropical malaria in the intensive care units of the University Hospital Zurich and the Stadtspital Triemli, Zurich, between 1991 and 1994. None of the 12 patients had been exposed to malaria before or had taken drugs for chemoprophylaxis. 7 patients survived, 5 died from complications of malaria. According to the criteria of severe tropical malaria defined by the WHO, the following pathological clinical and blood chemical parameters were noted on admission: cerebral coma (2/12); blood hemoglobin < 5 g/dl (0/12), < 8 g/dl (2/12); serum creatinine > 265 mumol/l (3/12); blood glucose < 2.2 mmol/l (0.12); circulatory
collapse
/shock (0/12); bleeding/signs of disseminated intravascular coagulation in laboratory tests (4/12); acidosis with pH < 7.25 (1/12). Further signs of severe tropical malaria were: hyperparasitemia > 5% (9/12); qualitative and quantitative disturbances of consciousness (6/12); thrombocytopenia < 30 x 10(9)/l (9/12); hyponatremia 125-135 mmol/l (9/12), < 125 mmol/l (2/12); rhabdomyolysis with creatine kinase > 1000 U/l (4/12). The basic treatment consisted of parenteral quinine hydrochloride in all patients; doxycycline was added in 8 cases, clindamycin in 3. Adjuvant therapy with desferrioxamin was given in 3 cases. 6 patients had exchange transfusions. Parasitemia cleared in all patients within 5 to 6 days. Later in the course, 5 patients developed acute respiratory distress syndrome, 6 required hemofiltration due to
oliguria
, and one became comatose.(ABSTRACT TRUNCATED AT 250 WORDS)

In order to evaluate the role of underlying disease in the high mortality observed in acute renal failure (ARF) and risk factors related to the development of oliguric ARF in renal allograft recipients, two groups were selected: 34 patients with native kidneys, aged 16 and 57 years, and presenting ischemic ARF caused by cardiovascular
collapse
, with no signs of infection at the time of diagnosis; and 34 renal allograft recipients who developed ARF immediately after transplantation, without rejection. ARF was defined either as 30% increase of basal plasmatic creatinine in patients with native kidneys or nonnormalization of plasmatic creatinine at day 5 after transplantation in renal allograft recipients;
oliguria
as diuresis < or = 400 mL/24 h. There were no differences in age, male frequency,
oliguria
presence and duration, need for dialysis, and infection episodes for renal allograft recipients and patients with native kidneys. The development of sepsis (3% and 41%) and death rate (3% and 44%) were higher in patients with native kidneys (p < 0.01). The renal allograft recipients with both oliguric (n = 18) and nonoliguric (n = 16) ARF were evaluated and no difference was observed in the recipient's age, donor's age, cold ischemia time, time elapsed until plasmatic creatinine normalization, donor's plasmatic creatinine or urea, and mean arterial pressure. No differences were observed between the groups regarding frequency of infection episodes during ARF and frequency of death. In conclusion, renal allograft recipients presented a lower death rate and were less susceptible to sepsis. Cold ischemia time, age, and hemodynamic characteristics of the donor did not affect the development of
oliguria
.

Thiamine deficiency can have cardiovascular and neurological manifestations. Cardiac beriberi is classically thought to represent a high-output state with
oliguria
and lactic acidosis. The condition can, however, also present itself with a low cardiac output and fulminant vascular
collapse
, or as an acute fatal form, causing sudden death, without clear-cut signs of cardiomegaly. In the western society beriberi is mainly encountered in alcoholics. We report on two cases, one with high-output failure and the other with low-output failure and cardiovascular
collapse
. In both patients the diagnosis of shoshin syndrome was made, and and both showed a spectacular improvement of congestive heart failure symptoms after treatment with thiamine. A therapeutic trial with thiamine is the only way to rapid diagnosis.

A male infant (gestational age, 26 weeks and 1 day; birthweight, 752 g) was treated for respiratory distress syndrome and thereafter required mechanical ventilation due to chronic pulmonary insufficiency. On the 34th day after birth, urine volume suddenly decreased and hypotension,
oliguria
, and generalized edema developed. Laboratory studies revealed rapid progression of severe hyponatremia and hyperkalemia. Although hypovolemic shock was suspected, the patient did not respond to conventional treatment of volume expansion and inotropic support. Only treatment with glucocorticoids was effective. Two weeks later, cranial ultrasonography revealed multiple, right-sided, cystic lesions that were subsequently diagnosed as cerebral infarction by magnetic resonance imaging. Several cases of extremely low birthweight infants with circulatory
collapse
after the acute period have been described recently, but the cause has been unclear. There has been no previous report of a case accompanied by cerebral infarction.

A case of Red-bellied Black snake envenomation resulting in intravascular haemolytic anaemia, rhabdomyolysis and anuric renal failure is described in the dog. A 12-year-old female desexed Golden Retriever was presented with a 15 hour history of profuse salivation, progressive lethargy, obtundence, inappetence and
collapse
. Significant findings on clinical examination were pallor, icterus, tachypnoea and dyspnoea with increased respiratory sounds and crackles in all lung fields. Generalised abdominal and muscular pain was apparent and dark red-brown urine was present around the perineal region. A diagnosis of Red-bellied Black snake (Pseudechis porphyriacus) envenomation was made and the dog was treated with intravenous fluid therapy, Tiger/Brown snake antivenom, packed red cell transfusions and Intermittent Positive Pressure Ventilation. Continued clinical deterioration occurred and a diagnosis of acute renal failure secondary to myohaemoglobinuric pigmenturia was made 12 hours after admission. Intensive treatment was attempted with diuresis and volume expansion.
Oliguria
and subsequent anuria ensued and the dog was euthanased due to a grave prognosis and lack of clinical response to treatment. Necropsy examination revealed muscular necrosis, accumulation of fluid in the thoracic and peritoneal cavities, and marked renal tubular necrosis with intraluminal occlusion secondary to pigmentary casts.

The ingestion of small amounts of glyphosate herbicide usually causes only mild symptoms. However, when large volumes of concentrates are ingested intentionally, it can generate potentially fatal symptoms that are refractory to treatment. It also is well known that the treatment for glyphosate poisoning is primarily of a supportive nature. We report two patients who intentionally ingested glyphosate herbicide, and both exhibited cardiovascular
collapse
and complicated renal failure despite the use of aggressive supportive therapy. Hemodialysis was conducted and the results were satisfactory; both patients were discharged without any sequelae. After analyzing these cases, we suggest that hemodialysis might have contributed to the favorable outcomes of our patients, and that there are several mechanisms that might justify the use of hemodialysis in these patients. In conclusion, physicians may wish to consider the early use of hemodialysis to improve the prognosis of patients exhibiting refractory hypotension and
oliguria
, despite vigorous supportive treatment in glyphosate herbicide intoxication.

Although the accumulation of gas is the most common cause of an expanding interpleural space, the presence of other structures or substances (hydrothorax, gastrothorax, hemothorax, urohemothorax, pyothorax, and chylothorax) under pressure may be sufficient to cause hemodynamic and respiratory compromise. We present two pediatric patients that developed hemodynamic and respiratory effects secondary to a chylothorax. The first patient presented in respiratory distress and cardiovascular
collapse
4 weeks after a Fontan procedure. Placement of a chest tube resulted in the release of chyle under pressure and prompt resolution of hemodynamic and respiratory symptoms. The second patient was a 2100 g neonate who developed a chylothorax during an episode of sepsis following gastroschisis repair. On two separate occasions, the development of the chylothorax was associated with tachycardia,
oliguria
, and increased requirements during mechanical ventilation. Chest tube placement resulted in the release of chyle under pressure and resolution of the symptoms. These two cases demonstrate that chylothorax like pneumothorax can have deleterious effects on hemodynamic and respiratory function.

A recent survey found that approximately 4% of very low birth weight infants in Japan were treated with glucocorticoids postnatally for circulatory
collapse
thought to be caused by late-onset adrenal insufficiency. We identified 11 preterm infants with clinical signs compatible with this diagnosis (hypotension,
oliguria
, hyponatremia, lung edema, and increased demand for oxygen treatment) and matched them for gestational age with 11 infants without such signs. Blood samples were obtained for cortisol and its precursors from the patient group before the administration of hydrocortisone, and from the control group during the same postnatal week. All samples were analyzed using a gas chromatography-mass spectrometry system. Cortisol concentrations did not differ between the two groups (6.6 +/- 4.5 vs 3.4 +/- 2.7 microg/dL); however, the total concentration of precursors in the pathway to cortisol production was significantly higher in the patient group (72.2 +/- 50.3 vs 25.0 +/- 28.5 microg/dL; p < 0.05). We conclude that the clinical picture of late-onset adrenal insufficiency in preterm infants is not a result of an absolute deficiency of cortisol production, but may be a result of a limited ability to synthesize sufficient cortisol for the degree of clinical stress.
