Experimental closed loop small intestinal volvulus was studied in the anesthetized horse. Volvulus was simulated by ligation of the mesenterial veins to a segment of small intestine. Physical signs and hemodynamic, hematologic, clinical chemical, bacteriologic and peritoneal fluid values were examined. Compared to conscious horses anesthesia highly delayed and modified the clinical signs of shock (changes in mucosal colour, dehydration, decreased skin temperature, elevated pulse rate, low blood pressures) and of small intestinal volvulus (altered peristalsis, gastric dilation). Plasma glucose response to shock was also modified by unconsciousness. However, a dose response relationship was indicated between the extent of small intestinal damage and clinical symptoms. The same was applicable to changes in blood pressures, blood acid-base balance, lactate, potassium, chloride, glucose, inorganic phosphorus, creatinine, creatine kinase, red blood cell and total white blood cell counts and serum total protein. The relationship was also indicated in the following peritoneal fluid values: volume, lactate, pH, total white cell counts, alkaline phosphatase and bacteriology. Changes related to shock (insufficient tissue perfusion) were low blood pressures and metabolic acidosis due to anaerobic glycolysis with accumulation of lactic acid. Also low plasma glucose and elevated plasma potassium, creatinine, inorganic phosphorus and creatine kinase were regarded as consequences of shock.

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 use of intestinal segments in the urinary tract can cause metabolic changes that depend on the intestinal segment utilized. The severity of these changes basically depends on the area of the intestinal mucosa in contact with urine, the duration of exposure to urine and renal function. The length of time the intestinal mucosa is in contact with urine largely depends on the surgical technique employed. It is longer for the reservoirs, intestinal neobladders and ureterosigmoidostomies than for the intestinal conduits with cutaneous urinary diversion and therefore carry a higher incidence of metabolic changes. Jejunal urinary diversion causes metabolic acidosis with hypochloremia, hyponatremia, hyperpotassemia, azotemia and dehydration in at least 50% of the cases. Ileal and colonic urinary diversion can cause metabolic acidosis, although the incidence is significantly less. Acidosis presents with hyperchloremia, hyperammonemia, hypersulfatemia, increased osmolality and uremia with normal creatininemia and a tendency to develop hypocalcemia, hypophosphoremia and hypomagnesemia. Recent studies performed in our service show that acidosis is basically due to the secretion of sodium bicarbonate by the intestinal segment used in the urinary tract, which causes water-salt depletion that is compensated by secondary hyperaldosteronism. Mild chronic acidosis is neutralized via the respiratory system and by the bone buffers, which leads to bone remodelling manifested by the significant increase of serum alkaline phosphatase levels and increased calciuria. These calcium phosphate changes, although statistically significant, do not appear to be important since they were not accompanied by changes of serum PTH levels, 25 and 1-25-cholecalciferol. Nicotinic acid as inhibitor of cyclic AMP synthesis failed to correct metabolic acidosis in the patients with transileal diversion.

We reviewed retrospectively a cohort of 80 patients with hyperemesis gravidarum hospitalized between 1976 and 1986 for the presence of abnormal liver enzymes and ketonuria. Thirteen (16%) had abnormal liver enzymes, generally less than four times the upper limit of normal. In this group, hyperemesis gravidarum began at the 14th week of pregnancy as compared to the 6th week in the normal enzyme group (p less than 0.01). Both groups were similar with regard to age, number of children and pregnancies, and duration of vomiting. Ketonuria was significantly more severe (p less than 0.01) in the abnormal enzyme group, implying a more severe state of starvation and dehydration. The correlation coefficient between the degree of ketonuria and level of liver enzymes was low for alkaline phosphatase (r = 0.18), GPT (r = 0.15), and GOT (r = 0.28). The concept that dehydration and starvation are important factors for the induction of liver cell injury is supported by our data. Lack of correlation between the degree of ketonuria and liver enzyme levels is suggestive of other mechanisms (hormonal, genetic) that may interact to produce transaminasemia.

Acute dehydration of diarrhoea of the breast-fed child is a type of hypovolemic shock which, by its severity and frequency is one of the major emergencies of pediatrics. The liver, as the site of many metabolic processes is mainly affected in the frame of the multiple-tissue involvement which is characteristic for this condition. The authors carried out a study of several enzymes (total LDH and the thermally-labile fraction, gluthamatdehydrogenase, gammaglutamyltranspeptidase, acid and alkaline phosphatase) in 27 breast-fed children. Determination of the enzymes was done on hospitalization, and 10 days later. The study showed that all the enzymes that were evaluated had moderate increases in 40.7-71% of all cases. The increases were significant (p less than 0.001). After 10 days the enzyme titers showed a tendency to become normal again, and slightly higher values were found in only 15-12% of all cases. Minimal hepatopathy can be considered, associated to the clinico-biological evolution of this severe conditions of the breast-fed child pathology.

A 6-year-old girl with cerebral palsy developed conscious disturbance and generalized convulsion after one-hour hot herb drug bath. Physical examination on admission revealed rectal temperature 41 degrees C, hot skin, respiration 46/min, regular heart beat 98/min, BP 130/60 mmHg, Glascow coma scale 4 (E2M1V1), soft and flat abdomen, no hepatosplenomegaly, no skin rash, no focal neurological sign, increased generalized muscle ton. Laboratory data showed CBC: WBC 20400 cumm (Neutrophils 31%, Lymphocytes 69%), Hb 11.6gm%, ESR 11 mm/hr, arterial blood gas: PH 7.077, PO2 43mmHg, PCO2 57.1mmHg, HCO3- 16 mEq/L, BE-11.5mEq/L, serum sodium 143 mEq./L, potassium 5.2 mEq/L, chloride 101 mEq/L, free calcium ion 3.8mg%, GOT 63IU/L, GPT 263 IU/L, amylase 193 IU/L, alkaline phosphatase 388 IU/L, LDH 1245 IU/L, CPK 677 IU/L, total bilirubin 0.8 mg/dl, direct type 0.1 mg/dl, BUN 18 mg/dl, Glucose 35 mg/dl. Urinalysis revealed proteinuria( ) trace hematuria and pyuria, but no cast. Lumbar puncture is within normal limits. Bacteriology including blood and CSF are normal. Multiple organ failure was noted at that time. Intensive cooling methods were performed including central and peripheral cooling. We used luminal and valium to control the seizure. Condition didn't improve. Afterwards cardiopulmonary arrest developed. Patient expired 8 hours after admission despite of resuscitation. Heat stroke in infancy and childhood is different from that in adulthood. The predisposing factors are high ambient temperature, dehydration, very young baby, sweat gland dysfunction, or ectodermal dysplasia. Definition of heat stroke includes 1) rectal temperature above 41 degrees C, 2) behavioral change, 3) warm skin, wet or dry.(ABSTRACT TRUNCATED AT 250 WORDS)

Recently, sensitive non-isotopic in situ hybridisation (NISH) methodology for the detection of human DNA and human papilloma virus (HPV) DNA in archival paraffin blocks of cervix was described. An amended protocol, now used in this laboratory for detection of these genes by NISH is presented. The amendments include the following: protease digestion at 37 degrees C; tissue dehydration in air rather than ethanol; stringency washing in formamide solution; blocking non-specific binding of avidin alkaline phosphatase with a modified buffer; and increasing the concentration of avidin alkaline phosphatase for detecting low abundance DNA. These changes simplify and increase the sensitivity of the protocol such that "Y" chromosome repeats are visualised in almost all female cells.

Twenty cows from a dairy herd consisting of 60 healthy, lactating Holsteins developed clinical signs of anorexia, mental derangement, dehydration, recumbency, and ruminal atony after ingesting water containing blue-green algae. Of the 20 cows, 9 died. The algal bloom, which developed in a stagnant pond during hot, dry weather, was identified as the cyanobacterium Microcystis aeruginosa, a potentially hepatotoxic algae. One week after the onset of toxicosis, affected cows seemed healthy, although liver-associated enzyme activities (alkaline phosphatase, gamma-glutamyl transferase, aspartate transaminase, and lactate dehydrogenase) were increased. Intraruminal administration of the intact wet bloom to a healthy 125-kg Angus heifer was followed by hepatic necrosis and death. The liver was large, friable, and gun-metal blue, with microscopically evident hepatocyte dissociation, degeneration, and necrosis. The ingesta of the heifer contained typical clumps of cells that were identified as M aeruginosa. The intraperitoneal administration of lyophilized cell material from that bloom to 18 mice caused marked hepatic enlargement. The intraperitoneal median lethal dose of the dried bloom was estimated to be 10 mg/kg of body weight. A cyclic peptide toxin purified from the algae seems to be similar structurally to toxins from other characterized hepatotoxic blooms of M aeruginosa.

Thirteen patients with systemic mast cell disease were studied in order to define the hepatic changes in this disease and to correlate the histologic lesions in the liver with the clinical findings. These patients often presented with multisystem disorders and 10 had hepatomegaly. Microscopically, the liver tissues in all patients showed fibrosis and chronic inflammatory cellular infiltration with plasma cells, lymphocytes, eosinophils, and mononuclear fibroblast-like cells in the portal area. The hepatic sinusoids were not significantly involved. A histologic diagnosis of systemic mast cell disease is seldom entertained in liver biopsy specimens embedded in paraffin and stained with hematoxylineosin, but can be facilitated in biopsy specimens embedded in plastic such as methacrylate. Tissue mast cells in the cellular infiltrate can be demonstrated best by special staining techniques with Giemsa, toluidine blue, and chloroacetate esterase. The severity of the histologic changes in the liver does not correlate well with the size of the liver or biochemical changes in the blood. Abnormal serum biochemical values were noted primarily in those with dehydration caused by diarrhea and vomiting, and in those with malnutrition. Hepatic function test results were usually normal, except for alkaline phosphatase level, which was elevated in all 13 patients. Although the clinical significance of hepatic involvement in systemic mast cell disease cannot be established with certainty in this study, it is believed that the prognosis of systemic mast cell disease is most intricately related to the systemic effects of mast cell involvement in many other organs, and not to hepatic involvement per se.

To delineate the spectrum of clinical expressions of distal, type 1 renal tubular acidosis in children and to update progress in diagnosis, therapy, and prognosis, the medical records of 14 girls and 10 boys, seen over a 7 year period, who met the following criteria, were examined: persistent urinary pH more than 6, net acid excretion less than 70 microEq/min/1.73 m2, simultaneous serum total CO2 less than 17.5 mEq/1, and normal or mild impairment of the glomerular filtration rate. The mean age at diagnosis was 8 months. The presenting signs and symptoms were failure to thrive (50%), vomiting and/or diarrhea (37.5%), dehydration (12.5%), and poor feeding (8.3%). Mean values +/- SD of serum calcium (9.8 +/- 0.8 mg/dl), inorganic phosphate (5.6 +/- 0.8 mg/dl), and alkaline phosphatase (222.6 +/- 96.1 U/l) were normal. Hyperkalemia (serum potassium above 5.0 mEq/l) was present at diagnosis in 13 children. Type 4 renal tubular acidosis was ruled out by the inability to achieve a minimum urine pH. With a mean follow-up period of 28.1 +/- 25.3 months, after alkali therapy at 3.3-3.5 mEq/kg/day had been administered for at least 12 months, the growth parameters improved as follows: the percentile weight (mean +/- SD) increased from the initial 11.8 +/- 7.5 to the final 27.6 +/- 31.3 (p less than 0.003), and the length/height percentile increased from 11.5 +/- 7.3 to 29.7 +/- 24.2 (p less than 0.03). The relationship between urine calcium/creatinine ratio and serum total CO2 showed poor correlation.(ABSTRACT TRUNCATED AT 250 WORDS)
