Three breast-fed infants of primiparous women had hypothermia, azotemia, and severe dehydration and malnutrition. No disease entities were identified. Although the cause of inadequate breast nutrition was unclear, these cases underscore the necessity for close follow-up and support of first-born breast-feeding babies.

Urethral obstruction induced in adult male cats caused clinical signs identical with those observed in naturally occurring disease. Central nervous system depression, anorexia, dehydration, vomiting, muscle weakness, and hypothermia occurred. Weight loss (due to water loss and catabolism), metabolic acidosis, mild hyponatremia, hyperkalemia, hypermagnesemia, hypocalcemia, hyperphosphatemia, hyperglycemia, azotemia, and hyperproteinemia were also observed. Serum amylase, alkaline phosphatase, and alanine aminotransferase activities were normal. Ten of 13 cats (group 1), with 72 hours' induced obstruction but not treated with parenteral fluids, died either before the obstruction was relieved or within 8 days afterward. Eight cats (group 2) with induced obstruction for 49 to 98 hours developed severe clinical and biochemical alterations. Treatment with a multiple-electrolyte solution, in addition to relief of urethral obstruction, resulted in favorable clinical and biochemical responses. These cats survived and were clinically healthy at 9 to 10 days after relief of obstruction. It was concluded that use of a multiple-electrolyte solution to correct acidosis, restore circulatory volume, and enhance renal excretion of potassium was effective supportive therapy after urethral obstruction was removed.

The prevalence, risk factors, and outcomes of delirium were studied in 229 elderly patients. Fifty patients (22%) met criteria for delirium; nondelirious elderly constituted the control group. Abnormal sodium levels, illness severity, dementia, fever or hypothermia, psychoactive drug use, and azotemia were associated with risk of delirium. Patients with three or more risk factors had a 60% rate of delirium. Delirious patients stayed 12.1 days in the hospital vs 7.2 days for controls and were more likely to die (8% vs 1%) or be institutionalized (16% vs 3%). Illness severity predicted 6-month mortality, but the effect of delirium was not significant. Delirium occurs commonly in hospitalized elderly, is associated with chronic and acute problems, and identifies elderly at risk for death, longer hospitalization, and institutionalization. The increased mortality associated with delirium appears to be explained by greater severity of illness.

Primary hypoadrenocorticism was diagnosed in ten young to middle-aged cats of mixed breeding. Five of the cats were male, and five were female. Historic signs included lethargy (n = 10), anorexia (n = 10), weight loss (n = 9), vomiting (n = 4), and polyuria (n = 3). Dehydration (n = 9), hypothermia (n = 8), prolonged capillary refill time (n = 5), weak pulse (n = 5), collapse (n = 3), and sinus bradycardia (n = 2) were found on physical examination. Results of initial laboratory tests revealed anemia (n = 3), absolute lymphocytosis (n = 2), absolute eosinophilia (n = 1), and azotemia and hyperphosphatemia (n = 10). Serum electrolyte changes included hyponatremia (n = 10), hyperkalemia (n = 9), hypochloremia (n = 9), and hypercalcemia (n = 1). The diagnosis of primary adrenocortical insufficiency was established on the basis of results of adrenocorticotropic hormone (ACTH) stimulation tests (n = 10) and endogenous plasma ACTH determinations (n = 7). Initial therapy for hypoadrenocorticism included intravenous administration of 0.9% saline and dexamethasone and intramuscular administration of desoxycorticosterone acetate in oil. Three cats were euthanatized shortly after diagnosis because of poor clinical response. Results of necropsy examination were unremarkable except for complete destruction of both adrenal cortices. Seven cats were treated chronically with oral prednisone or intramuscular methylprednisolone acetate for glucocorticoid supplementation and with oral fludrocortisone acetate or intramuscular injections of repository desoxycorticosterone pivalate for mineralocorticoid replacement. One cat died after 47 days of therapy from unknown causes; the other six cats are still alive and well after 3 to 70 months of treatment.

Clinicopathologic findings were retrospectively evaluated in 26 cats and 24 dogs with ethylene glycol intoxication. Common clinical signs were ataxia, depression, vomiting, and hypothermia. Characteristic alterations in the hemogram and serum chemical profile included neutrophilia, lymphopenia, azotemia, hyperphosphatemia, hypocalcemia, hyperglycemia, and decreased whole blood bicarbonate. Common urinalysis findings included isosthenuria, proteinuria, glucosuria, hematuria, calcium oxalate and hippurate crystalluria, and the presence of renal epithelial cells, white blood cells, and granular and cellular casts in the urine sediment. The high death rate (78%) was attributed to delays in presentation, diagnosis, and therapy.

In four infants of primiparous mothers, critical dehydration, hypothermia, and azotemia developed while they were being breast-fed exclusively. Three had significant hypernatremia, one had a perforated duodenal ulcer, and one had transient renal failure. Although the causes of the inadequate nutrition are unclear, these cases emphasize the necessity of close follow-up for breast-fed babies, especially those of primiparous mothers and those in whom there has been excessive weight loss while in the hospital.

Following the Exxon Valdez oil spill, 347 oiled sea otters (Enhydra lutris) were treated in rehabilitation centers. Of these, 116 died, 94 within 10 days of presentation. Clinical records of 21 otters dying during the first 10 days of rehabilitation were reviewed to define the laboratory abnormalities and clinical syndromes associated with these unexpected deaths. The most common terminal syndrome was shock characterized by hypothermia, lethargy, and often hemorrhagic diarrhea. In heavily and moderately oiled otters, shock developed within 48 hours of initial presentation, whereas in lightly oiled otters shock generally occurred during the second week of captivity. Accompanying laboratory abnormalities included leukopenia with increased numbers of immature neutrophils (degenerative left shift), lymphopenia, anemia, azotemia (primarily prerenal), hyperkalemia, hypoproteinemia/hypoalbuminemia, elevations of serum transaminases, and hypoglycemia. Shock associated with hemorrhagic diarrhea probably occurred either as a direct primary effect of oiling or as an indirect effect secondary to confinement and handling in the rehabilitation centers. Lightly oiled otters were less likely to die from shock than were heavily oiled otters (22% vs. 72%, respectively). Heavily oiled otters developed shock more rapidly and had greater numbers of laboratory abnormalities, suggesting that exposure to oil was an important contributing factor.

Of 427 human immunodeficiency virus-seropositive patients admitted to the Robert Wood Johnson University Hospital from January 1986 through August 1992, seven had Clostridium difficile enteric infection documented by the presence of cytotoxin B in the stool, without other enteric infection. All seven patients had AIDS, and all had recently received antibiotics. These patients had a severe clinical presentation of C. difficile infection. All patients had profound watery diarrhea, with a mean of 20 +/- 14 (SD) bowel movements per day. Four had fever > 38.5 degrees C, and another had hypothermia. Three patients had borderline hypotension, and another was orthostatic. The mean pulse was 119 +/- 26 (SD) beats/min. Five patients had abdominal pain and tenderness. Two had occult blood in the stool. Four had metabolic derangements such as hyponatremia, hypokalemia, or prerenal azotemia. Three of four patients undergoing abdominal roentgenography had radiographic findings consistent with severe colitis of colonic dilation, mural thumbprinting, or mural thickening. Sigmoidoscopic findings ranged from diffuse erythema to prominent pseudomembranes. During a mean interval of 14.3 +/- 6.2 (SD) days before institution of specific antibiotic therapy, the diarrhea spontaneously resolved in only one of the seven patients. In the others, the diarrhea resolved on average 7.3 +/- 4.0 (SD) days after instituting antibiotic therapy. During a mean follow-up of 4.4 +/- 6.3 (SD) months, only two patients redeveloped diarrhea. Both patients had recurrent C. difficile colitis; the symptoms again rapidly resolved after repeat antibiotic therapy. We conclude that in patients with AIDS C. difficile may present as a severe enteric infection with profound diarrhea due to immunosuppression, that the diarrhea may be prolonged and not remit spontaneously, and that the diarrhea usually rapidly resolves with specific antibiotic therapy.

Between May 1993 and August 1994, 15 patients (10 men) with type A aortic dissection (9 acute) had a replacement of the ascending aorta and/or aortic arch with circulatory arrest with profound hypothermia and retrograde cerebral perfusion. Mean circulatory arrest time was 47.5 min (range 23 to 68 min). Three patients (20%) died in relation to postoperative bleeding. No patient had a new neurologic damage related to surgery. Ten patients were awake and oriented before 24 hours of the operation and another one before 48 hours; 4 patients required more than 48 hours to be completely awake and oriented. Two patients were operated on with a recent stroke. One of them recovered without sequelae before hospital discharge and the other one had a major regression of his brain damage. Two other patients had emergency surgery because of cardiac tamponade and cardiogenic shock. Both of them had a satisfactory recovery. Six patients presented azotemia but only 2 of them needed dialysis. There was no case of Q wave infarction nor congestive heart failure in the perioperative period. Follow-up was 100% completed (12 patients) with a mean of 9.8 months (range 5 to 18 months). One patient died on the 10th postoperative month because of a late infectious process. Eight patients are in functional class I and 3 in II. Ten of them are back to their usual activities'. Although retrograde cerebral perfusion is a new surgical technique, it seems to be a very valuable complement for brain protection in ascending aorta and/or aortic arch surgery with circulatory arrest with profound hypothermia.

From 1982 to 1994, 45 patients (1.22 episodes per 10,000 discharged patients) were treated for citrobacter bacteremia at National Taiwan University Hospital (Taipei). All patients had at least one underlying disease. Citrobacter bacteremia most commonly occurred in patients with malignancies (48.9%) or hepatobiliary stones (22.2%). Intraabdominal tumors comprised the majority (59.1%) of malignancies. Bacteremia commonly originated from sites such as the abdominal cavity (51.1%), urinary tract (20%), and lung (11.1%). Polymicrobial bacteremia was diagnosed in 15 patients (33.3%); for nine (60%) of these patients, the source of the infection was intraabdominal. Prior treatment with a third-generation cephalosporin was significantly associated (P < .01) with the development of multidrug resistance among the isolates. The mortality associated with citrobacter bacteremia was 17.8%. Poor prognostic factors included pneumonia, altered mental status on presentation, hypothermia, oliguria, septic shock, deterioration in mental status, hyperbilirubinemia, azotemia, and thrombocytopenia. Combination therapy, as compared with other regimens, improved the outcome of citrobacter bacteremia.
