To determine the reliability with which inorganic phosphorus (phosphate) concentrations can be used to predict major intestinal injury associated with equine colic, phosphate concentrations were measured in serum, peritoneal fluid, or both from 9 clinically normal adult horses (group A), 37 horses successfully managed medically for signs of abdominal pain (group B), 26 horses with signs of abdominal pain and undergoing exploratory laparotomy without intestinal resection (group C), and 26 horses undergoing intestinal resection or euthanasia for extensive intestinal lesions (group D). Peritoneal fluid phosphate concentration was significantly greater in horses in group D (mean, 4.58 +/- 0.34 mg/dl) than in horses in group A (mean, 2.78 +/- 0.21 mg/dl), group B (mean, 2.92 +/- 0.27 mg/dl), and group C (mean, 2.98 +/- 0.28 mg/dl; P less than or equal to 0.01). Serum phosphate concentration was significantly greater in horses in group D (mean, 3.87 +/- 0.30 mg/dl) than in horses in group A (mean, 2.73 +/- 0.22 mg/dl), group B (mean, 2.80 +/- 0.21 mg/dl), and group C (mean, 2.78 +/- 0.22 mg/dl); P less than or equal to 0.05). There was significant (P less than or equal to 0.001) correlation between serum and peritoneal fluid phosphate concentrations within each group and when pairs from all groups were pooled. When peritoneal fluid phosphate concentrations exceeded 3.6 mg/dl, intestinal lesions requiring resection or euthanasia were predicted with sensitivity of 77% and specificity of 76%. When serum phosphate concentrations exceeded 3.3 mg/dl, such lesions were predicted with sensitivity of 60% and specificity of 73%.(ABSTRACT TRUNCATED AT 250 WORDS)

A case of intestinal talcosis in a 46-year-old man is reported. At the age of 27, the patient was treated for pulmonary tuberculosis with tablets containing talc (183 g talc per 2,670 g total drug intake) over a period of 28 months. Eighteen years later, the patient was hospitalized for abdominal pain that remained refractory to antacids; he subsequently underwent a right hemicolectomy. Light-microscopic examination revealed a prominent fibrosis of the intestinal wall in which birefringent particles were demonstrated by polarized light. Using energy-dispersive spectroscopy, an analysis of these particles showed that they were predominantly composed of silicon and magnesium as well as small amounts of phosphorus, sulphur, calcium, and iron--the spectrum typically associated with talc. We believe that the source of this talc is the tablets ingested by the patient during prior antituberculosis therapy.

A 13-year-old girl presenting with abdominal pain, polyuria, polydipsia, and radiologically confirmed renal calculi was diagnosed as having primary hyperparathyroidism. Laboratory data revealed markedly elevated serum calcium, low phosphorus, and elevated parathyroid hormone. Other parathyroid function tests also confirmed the diagnosis of primary hyperparathyroidism. Ultrasound examination showed a small echogenic nodule in the parathyroid gland. Following a single gland resection, the extremely high serum calcium level promptly decreased to normal range, and it has remained normal.

Twenty-six adult patients with histologically confirmed celiac disease on gluten-free diet after apparent disease remission were reexamined at 4-6 months intervals for a mean period of 55.4 months (range 13-137). Eight patients remained clinically well with normal blood tests. Eighteen patients had clinical or biological abnormalities. Eleven patients reported repeated episodes of meteorism and abdominal pain and/or diarrhea which disappeared in 2 after lactose withdrawal. Iron deficiency and macrocytic anemia were sometimes observed in 5 and 4 patients respectively. Altered plasma calcium, phosphorus and alkaline phosphatase and/or bone densitometry findings were detected in 7 patients. Seventeen patients (12 presenting some of the above findings) agreed to a repeat biopsy: 13 of these showed grade II and 4 grade III abnormalities. Although adult celiac patients may show marked improvement during gluten-free diet, minor clinical disturbances and biochemical abnormalities may still be present.

Clinical and laboratory findings in 25 adults, ages ranging from 18 to 40 years, who were hospitalized for problems related to paint sniffing are presented. All but one were chronically unemployed. Three different patterns of symptoms led to hospitalization: muscle weakness (n = 9), gastrointestinal complaints including abdominal pain and hematemesis (n = 6) and neuropsychiatric disorders including altered mental status, cerebellar abnormalities, and peripheral neuropathy (n = 10). Hypokalemia (n = 13), hypophosphatemia (n = 10), hyperchloremia (n = 22), and hypobicarbonatemia (n = 23) were common. The average serum potassium and phosphorus concentrations of 1.7 mmol/L and 1.5 mg/dL were significantly lower in the muscle weakness group than in the other two groups. Rhabdomyolysis occurred in 10 patients. Hyperchloremic acidosis was found in 19 of 22 patients evaluated. The muscle weakness and gastrointestinal syndromes resolved within 1 to 3 days with abstinence from sniffing and repletion of fluid and electrolyte stores. Inhalation of paint or glue vapors should be considered in the differential diagnosis of the symptoms and laboratory findings described above.

Ten cases of ingestion of yellow phosphorus rat poison, including four cases that occurred during the past 3 years, are reported. Comparison of these cases with 82 others from the literature showed that ingestion of yellow phosphorus paste often results in clinical findings that are different from those described for acute yellow phosphorus poisoning in current toxicology texts. The time lag between swallowing of the poison and onset of symptoms varied from a few minutes to 24 h. Garlic odor, mucosal burns, and phosphorescent vomitus or feces occurred in only a small percentage of cases. Diarrhea was not a presenting complaint. Initial symptoms were referable to the gastrointestinal tract, central nervous system, or both. Mortality rates were 23% for patients who had early symptoms of vomiting or abdominal pain; 73% for those where the first manifestation of intoxication was restlessness, irritability, drowsiness, stupor, or coma; and 47% for patients who had a combination of these GI and CNS symptoms initially. Applying standard diagnostic criteria for yellow phosphorus poisoning to patients who have consumed yellow phosphorus pastes may result in serious diagnostic errors.

Our objective was to monitor serum and urine biochemical changes after oral sodium phosphate cleansing in a prospectively designed study. The study subjects were seven healthy, asymptomatic adults. Sodium phosphate 45 ml diluted in 45 ml water was given orally at baseline and 12 hr later. Calcium, ionized calcium, phosphorus, sodium, potassium, creatinine, and PTH were analyzed at 2, 4, 6, 9, 12, 14, 16, 18, 21 and 24 hr after the first challenge. Urinary calcium, phosphorus, sodium, potassium, and cyclic AMP were analyzed at baseline and every 2 hr after oral sodium phosphate. Blood pressure, pulse, and respiratory rate were recorded every 2 hr and symptom questionnaires using visual analog scales were completed. A marked rise in phosphorus (peak range 3.6-12.4 mg/dl, P < 0.001) and falls in calcium (P < 0.001) and ionized calcium (P < 0.001) were seen. Rises seen in PTH and urinary cAMP confirmed the physiologic significance of the biochemical effect. There were no significant changes in other serum and urine laboratory or clinical assessments. Reported significant symptoms included bloating, cramps, abdominal pain, and nausea. Significant hypocalcemia and hyperphosphatemia after oral sodium phosphate raises concern about its use in normal individuals. Oral sodium phosphate should not be administered in patients with cardiopulmonary, renal, or hepatic disease.

Thirty-four patients, aged 3 to 17 years, were randomized to receive oral sodium phosphate solution or a polyethylene glycol-based solution in preparation for elective colonoscopy. Nineteen patients received two doses of oral sodium phosphate solution (45 mL/1.7 m2/ dose) and 15 received polyethylene glycol-based solution (4 L/1.7 m2). Compliance with oral sodium phosphate solution was judged as easy or tolerable in 15 of 19 patients, but only in 5 of 15 who were given polyethylene glycol-based solution. The quality of colon cleansing was rated by an endoscopist who was blinded to the colon preparation method used. The bowel preparation was excellent or good (only liquid remaining in the colonic lumen) in 18 of 19 patients who received oral sodium phosphate solution and in 6 of 15 who received polyethylene glycol-based solution. The incidence of vomiting was similar in both groups, but abdominal pain occurred more frequently in the polyethylene glycol-based solution group. Hyperphosphatemia developed in patients who received oral sodium phosphate solution (serum phosphorus = 2.3 +/- 0.7 mmol/L (7.2 +/- 2.2 mg/dL; mean +/- SD), but only in 1 of 15 patients in the polyethylene glycol-based solution group. Patients did not exhibit symptoms of hyperphosphatemia and serum calcium concentrations were similar in both groups. In summary, oral sodium phosphate solution is better tolerated than polyethylene glycol-based solution for bowel preparation in children. However, hyperphosphatemia occurred frequently in patients who received oral sodium phosphate solution. Further studies are needed to determine the optimal dose for safety and efficacy for the use of these solutions in children.

Hypercalciuria is a common problem causing symptoms such as abdominal pain, hematuria and enuresis, and leading to stone formation. It results from a renal tubular calcium "leak" or intestinal hyper-reabsorption of calcium. This study was performed to determine whether renal functional impairment was present in children with hypercalciuria. The study group comprised 298 children who were screened for hypercalciuria by means of urinary calcium/creatinine (UCa/UCr) ratio. The renal functions of 18 children (6.4%) detected as having hypercalciuria with Ca/Cr ratios of greater than 0.18 in their spot urines were evaluated. Results were compared with those of the healthy control group. The rate of hypercalciuria did not very significantly between the boys and girls (p > 0.05). The mean value of daily calcium excretion was 6.42 + 3.93 mg/kg/day in the children with hypercalciuria, which was significantly different from that of the control group (p < 0.01). When the values of creatinine, osmolar and free water clearances, fractional excretion of sodium and tubular reabsorption of phosphorus were compared between the patient and control groups, the difference was not significant (p > 0.05). Urinary N-acetyl-beta-D-glucosaminidase (NAG) excretion, which was described as the creatinine ratio, was significantly higher in the children with hypercalciuria. These findings suggest that in the presence of normal renal functional studies in children with hypercalciuria, tubular injury can be detected by NAG, which is a more sensitive marker of renal tubular injury.

Patients studied here suffered from chronic colitis characterized by vague lower abdominal pain, bleeding per rectum with diarrhoea and palpable tender descending and sigmoid colon. The inflammatory process in colitis is associated with increased formation of leukotrienes causing chemotaxis, chemokinesis, synthesis of superoxide radicals and release of lysosomal enzymes by phagocytes. The key enzyme for leukotriene biosynthesis is 5-lipoxygenase. Boswellic acids were found to be non-redox, non-competitive specific inhibitors of the enzyme 5-lipoxygenase. We studied the gum resin of Boswellia serrata for the treatment of this disease. Thirty patients, 17 males and 13 females in the age range of 18 to 48 years with chronic colitis were included in this study. Twenty patients were given a preparation of the gum resin of Boswellia serrata (900 mg daily divided in three doses for 6 weeks) and ten patients were given sulfasalazine (3 gm daily divided in three doses for 6 weeks) and served as controls. Out of 20 patients treated with Boswellia gum resin 18 patients showed an improvement in one or more of the parameters: including stool properties, histopathology as well as scanning electron microscopy, besides haemoglobin, serum iron, calcium, phosphorus, proteins, total leukocytes and eosinophils. In the control group 6 out of 10 patients showed similar results with the same parameters. Out of 20 patients treated with Boswellia gum resin 14 went into remission while in case of sulfasalazine remission rate was 4 out of 10. In conclusion, this study shows that a gum resin preparation from Boswellia serrata could be effective in the treatment of chronic colitis with minimal side effects.
