A retrospective review of cases seen in the Diarrhea Treatment and Training Unit (DTU) of Bangalore (India) Medical College's Vani Vilas Children's Hospital during 1992-1994 confirmed the efficacy of the standard case management approach. This strategy entails oral rehydration therapy (ORT), continued feeding, and selective use of intravenous fluids and antibiotics. Of the 7966 children (4374 males and 3592 females) reporting to the DTU during the 2-year study period, only 2412 (30.5%) had received oral rehydration solution (ORS) or home-available fluids before admission. Acute watery diarrhea was present in 7316 cases (91.84%). Death occurred in 59 acute watery diarrhea cases, 6 dysentery cases, and 7 persistent diarrhea cases. The average time for cases managed in the ORT area was 2 hours and 45 minutes, while the hospital stay for admitted cases averaged 3 days. In 6957 cases (87.33%), ORS was sufficient treatment. Of the 1009 children (12.67%) who required intravenous fluids, 254 had dehydration attributable to conditions such as persistent vomiting and inability to drink due to oral thrush. Only the 512 children (6.2%) with cholera and dysentery received antibiotics. Of the 72 children who died (case fatality rate, 0.9%), 43 had associated severe malnutrition with pneumonia and anemia, 14 had a central nervous system infection, and 13 had septicemia; in only 2 cases could death be directly ascribed to diarrheal disease. One of these cases was due to shigella encephalopathy and the other to severe dehydration with acidosis. The average cost of treatment per patient was Rs 2.91 when only ORS was used compared with Rs 24.28 when intravenous rehydration was required. The finding that less than one-third of children had received ORS before admission suggests a need for the establishment of more DTUs in large hospitals that can train community-based health personnel in diarrhea case management.

Combined sepsis and rhabdomyolysis result in a mortality rate much higher than that caused by each process alone. An analogous rat model is obtained by simultaneous i.p. administration of a nonlethal dose of lipopolysaccharide (LPS 0.025 mg/100 g) and a nonlethal i.m. injection of glycerol (1 ml/100 g). The aim of this study was to determine the factors contributing to the high mortality rate in this rat model. The factors examined include: Dehydration, plasma volume expansion, 'immunization' to glycerol, induction of LPS tolerance and the effect of free radicals formed in this model. Neither dehydration nor volume expansion affected mortality. 'Immunization' with glycerol was also not effective. In contradistinction, tolerance to LPS achieved by a daily injection with gradual increasing doses of LPS (from 0.05 mg/100 g to 1 mg/100 g) for 6 days reduced the mortality rate by 60% (P < 0.001). Moreover, decreasing free radical activity using the natural antioxidant (NAO) (5 mg/100 g) reduced mortality rates by 50%. A different antioxidant, dimethylthiourea (DMTU) (50 mg/100 g) failed to reduce mortality rates. This study suggests that the synergism between glycerol and LPS is apparently due to an increase in the rats' sensitivity to endotoxin following glycerol injection. However, endotoxin apparently does not enhance sensitivity to glycerol in the rat. The new antioxidant NAO significantly reduced the high mortality rate.

From 1984 through 1992, staff at The Marine Mammal Center (TMMC, Sausalito, California, USA) examined 207 northern elephant seals (Mirounga angustirostris) with a condition of unknown etiology called northern elephant seal skin disease (NESSD). The skin lesions were characterized by patchy to extensive alopecia and hyperpigmentation, punctate or coalescing epidermal ulceration, and occasionally, massive skin necrosis. Microscopic lesions included ulcerative dermatitis with hyperkeratosis, squamous metaplasia and atrophy of sebaceous glands. All diseased seals were less than 2 years of age and suffered from emaciation, depression, and dehydration. Mortality from septicemia increased significantly with severity of skin ulceration. Compared to 14 apparently unaffected seals, diseased seals had depressed levels of circulating thyroxine, triiodothyronine, retinol, serum iron, albumin, calcium, and cholesterol. Levels of alanine aminotransferase, aspartate aminotransferase, lactate dehydrogenase, gamma glutamyl transpeptidase, blood urea nitrogen, and uric acid were elevated. Morphometrically, diseased animals were approximately 15% smaller than normal seals of the same sage. Serum and blubber concentrations of 36 polychlorinated biphenyl congeners (sigma PCB) and dichloro-diphenyl-dichloroethylene (p,p'-DDE) were negatively correlated with body mass. Mean concentrations of sigma PCB and p,p'-DDE in serum in diseased seals were elevated as compared to apparently normal seals. Etiology of this syndrome remains unknown, but the possibility of PCB toxicosis cannot be ruled out.

The objective of this paper is to report 5 cases of rhabdomyolysis (RML) in patients with acute leukemia (AL). This occurred consecutively after the administration of chemotherapy, during the ensuing period of myelosuppression. Thirty-six patients with AL received, in a three-month period, 51 cycles of combined chemotherapy which included, in all of them, cytosine arabinoside (ARA-C); among them, along with myelosuppression, five experienced fever, infectious complications, gastrointestinal tract symptoms and severe myalgias. Serum creatine kinase (CK), liver function tests and a light microscopy muscle biopsy were performed on all of them. Ten-17 days after receiving chemotherapy, five patients (4 males and 1 female) with acute lymphoblastic leukemia developed incapacitating myalgias in neck, thighs and arms. CK and/or alanine aminotransferase and aspartate aminotransferase were increased 5-24 times above the normal range in four of these patients, and the muscle biopsy showed focal RML in all five. Myalgias were self-limited and lasted 4-10 days. In addition to the chemotherapy, other factors known to be capable of producing RML, such as sepsis, other medications, and dehydration were found. In conclusion, myalgias were due to focal RML produced probably by a combination of factors, particularly the chemotherapy along with dehydration due to gastrointestinal complications, infection, and the use of diverse antibiotics. The endemic nature of the finding in such a short period of time is outstanding.

The most common diagnoses of elderly patients in the emergency department (ED) were compared among three age subgroups: 65 to 74, 75 to 84, and 85 and older. The computerized billing records for patient visits to 10 northern New Jersey hospital EDs for the years 1985 to 1991 were retrospectively analyzed. The most frequently occurring ICD-9-CM codes for elderly patients were compared among the three age subgroups. Elderly persons comprised 174, 146 (14% of the total) patient visits. The 176,146 patient visits were assigned 259,440 ICD-9-CM codes. The most common ICD-9-CM codes for medical diagnoses included chest pain, cardiac dysrhythmias, congestive heart failure, syncope, abdominal pain, and dyspnea. Fractures, particularly of the lower limb and upper limb; contusions; open wounds, particularly of the head, neck, and trunk; and falls were among the most common trauma diagnoses. The proportions in the three age subgroups of each diagnosis were statistically significantly different, except for cardiac arrest and contusions of the trunk and of multiple sites. The diagnoses with clinically significant higher relative risks in older age subgroups were atrial fibrillation, congestive heart failure, syncope, hypovolemia/dehydration, gastrointestinal hemorrhage, dyspnea, pneumonia, pulmonary edema, cerebrovascular accident, septicemia, urinary tract infection, fractures, and open wounds of the head, neck, trunk, particularly the scalp, and falls. Clinically significant lower relative risks were found in older age subgroups for chest pain, acute myocardial infarction, hypertension, angina, chronic airway obstruction not elsewhere classified, epistaxis, contusions of the upper limb, and open wounds of the finger.

We evaluated factors associated with mortality among a cohort of malnourished children with persistent diarrhoea (PD) admitted for nutritional rehabilitation with a defined rice-lentil (Khitchri) and yoghurt diet. Of 302 children consecutively admitted with PD, 13 (4 per cent) died, mostly (62 per cent) within 72 h of admission. Univariate analysis of risk factors at admission associated with mortality indicated significantly increased risk of death with severe stunting [relative risk (RR) 3.1, 95 per cent confidence interval (CI) 1.1-9.0], hypoalbuminaemia (RR 4.3, 95 per cent CI 1.5-12.3), stool frequency > 12/day (RR 6.0, 96 per cent CI 2.0-17.6), stool volume > 100 g/kg/day (RR 10.7, 95 per cent CI 3.0-37.6) and severe dehydration (RR 7.5, 95 per cent CI 2.6-21.8). Children who died also had comparatively shorter duration of diarrhoea at admission, and were also associated with higher rate of bacteremia at admission (Fisher's exact test P < 0.01). The logistic regression model evaluating multivariate risk of mortality identified weight-for-age z-score and sepsis as significant risk factors. Our data suggest that severe malnutrition and sepsis are associated with significantly increased risk of mortality in children with PD. Stringent screening for infections and recognition of subgroups with severe malnutrition and severe diarrhoea may improve screening and case management strategies for this disorder.

Adults and children have cardiac arrests for very different reasons. The commonest reason for an adult cardiac arrest is a primary arrhythmia in association with ischaemic heart disease, i.e. ventricular fibrillation. Children have cardiac arrests because of respiratory failure, hypovolaemia (due to trauma and dehydration) and sepsis.

Renal vein thrombosis (RVT) is the most frequently occurring vascular condition in the new-born kidney. The predisposing factors include dehydration, sepsis, birth asphyxia, maternal diabetes, polycythaemia and the presence of an indwelling umbilical venous catheter. (RVT) may present clinically with a flank mass, haematuria, hypertension or renal failure. Many imaging modalities have been employed, but ultrasound is the technique most commonly used in the evaluation of neonates with suspected RVT. Thrombosis commences in the small renal veins and subsequently propagates via larger interlobar veins to the main renal vein and inferior vena cava (IVC). The ultrasound appearances depend upon the stage at which the examination is performed and extent of the thrombus. Initially, the interlobular and interlobar thrombus appears as highly echogenic streaks. These streaks commence in a peripheral, focal segment of the involved kidney and only persist for a few days. In the first week the affected kidney swells and becomes echogenic with prominent echopoor medullary pyramids. Later, the swelling increases and the kidney becomes heterogenous with loss of corticomedullary differentiation. Grey scale ultrasound readily demonstrates thrombus within the renal vein and IVC. Adrenal haemorrhage is a recognized association and may be identified ultrasonically. Colour Doppler scanning provides additional information. In the early stages of RVT, colour Doppler may demonstrate absent intrarenal and renal venous flow. Ultimately, the kidney may recover, show focal scarring or become atrophic. Thus, ultrasound provides an accessible and reliable tool in the assessment of suspected neonatal RVT.

Most patients with Crohn's disease have to be operated on. Necessity to loose some amount of the intestine and time-point of the surgical intervention may be derived from the irreversible cascade of the inflammatory process and the limitations of the conservative treatment. In ileocecal disease indications for surgery are represented by stenotic and/or penetrating complications of the inflamed bowel, whereas in Crohn's colitis acute or terminal medical refractority is predominating. Standard-procedures result from constantly definable patterns of the disease manifestation: ileocecal resection and colectomy/-proctocolectomy. In segmental colitis sometimes "resections within Crohn's" may be adequate in a first attempt to avoid anticipating the natural course by surgical means. In these cases the further prognosis depends on the treatment possibilities of the remaining colon. In contrast, true recurrence is a new inflammation of the neoterminal ileum and may indicate repeated resections. The frequence decreases with the number of resections. Nevertheless nutritional status is restored even by multiple resections, whereas specific functional sequelae of the resection--distal resection- and dehydration syndromes--are well treatable mostly. In the case of appropriate timing of the operation and the reoperation operative morbidity and mortality are remarkable low today resulting in an almost normal life expectancy. Most important as negative prognostic factor remains sepsis resulting from pre-existing or postoperative infectious complications. Keeping this in mind experimental pharmaco-therapy to delay the operation and not profoundly substantiated tendencies to minimize surgery are to be considered only with critical scepticism. At the moment, future research is thought to be more successful in focussing prophylaxis of ileal recurrence than avoiding surgery.

Twenty-one compromised neonatal foals hospitalised at the Rural Veterinary Centre (RVC) during 1993 were studied to determine i) serum gentamicin concentrations obtained when gentamicin was administered at 3.3 mg/kg bwt twice daily i.m.; ii) factors which contributed to inter-foal variation in serum gentamicin concentrations achieved and iii) clinical efficacy of gentamicin therapy in foals with confirmed septicaemia. Septicaemia was confirmed in 7 foals with positive blood cultures and suspected in 8 foals with a sepsis score > 11. Peak serum concentrations (Ps) were > 6 microg/ml in all foals and > 8 microg/ml in 60% of foals. Trough serum concentrations (Ts) were < 2 microg/ml in all foals. Factors found to produce inter-foal variation in the Ps achieved included age (< 24 h; decreased), bodyweight (< 38 kg; decreased) and severity of dehydration (8-12% bodyweight; increased). Clinical response was not associated with achievement of Ps > 8 microg/ml, but was negatively influenced by the severity of clinical signs of depression. None of the foals in this study developed septic arthritis or pneumonia during or after therapy. No serum biochemical evidence (i.e. elevated serum creatinine concentrations) of gentamicin-induced nephrotoxicity was noted during therapy.
