For proper use of systemic GCS, a basic knowledge of the normal HPA axis, as well as knowledge of the pharmacology, clinical usage guidelines, and adverse reactions of these agents is imperative. Both short-term (acute) and long-term side effects should be well known by the physician. The pros and cons of oral and parenteral therapy for various disorders and in various situations should be recognized. For long-term therapy, an intermediate-acting agent such as prednisone in single, early morning doses is most commonly used to minimize suppression of the HPA axis. Alternate-morning doses produce even less suppression if the disease process will respond. A through patient history, including general medical history and medications the patient is taking, is important to anticipate any potential problems. Weight and blood pressure should be checked initially and every 1 to 3 months thereafter. Blood glucose, electrolytes, and lipid studies, including triglycerides, should be done approximately every 6 months. An ophthalmology examination should be performed every year, and stool examination for occult blood and chest radiography can be obtained as indicated. Bone density studies might be necessary in patients who are at high risk for osteoporosis. Specific acute situations may dictate other studies. The patient on long-term GCS should be kept as active as possible, as mild-to-moderate exercise helps prevent certain side effects, such as osteoporosis. The dose of oral GCS is best given with food to prevent gastrointestinal irritation, and agents to decrease gastric acidity might be needed in certain situations. Exposure to infections should be prevented, where possible, and treatment initiated at the first sign of systemic or cutaneous infection. Pain should be evaluated early, especially abdominal pain or bone pain; MRI is indicated if aseptic necrosis of bone is suspected. Both trauma and severe sun exposure should be avoided. Consultation with other specialists is strongly recommended when the situation dictates. Diet is one of the most important strategies to minimize side effects from long-term GCS therapy. Vegetable protein should be increased in the diet, and fats and carbohydrates limited. Adequate calcium is imperative, and calcium supplementation is recommended for high-risk osteoporosis patients. Small amounts of vitamin D may be necessary to increase absorption of calcium. Restriction of sodium is also important, as is maintainance of dietary potassium. Supplemental potassium may be necessary in some patients, and a thiazide diuretic might be useful in patients with hypertension, edema, or osteoporosis. Vitamin C can be given to promote wound healing. A good doctor-patient relationship is important in managing the patient on long-term GCS. The patient must return for regular visits and be encouraged to promptly report any adverse reactions to the physician. If these criteria are maintained and the strategies noted previously are followed, problems from long-term therapy with GCS will be minimized.

Pediatric cases of black widow spider envenomation (BWSE) were reviewed in order to assess the morbidity and mortality in children with BWSE, and to make recommendations for optimal therapy. The methodology includes a retrospective chart review in an urban pediatric tertiary care hospital. Included were all pediatric patients admitted with the BWSE diagnosis in the last 10 years (1984-1994). The results are based on 12 children with ages ranging from 15 months to 18 years. The BWSE syndrome is characterized by several common systemic effects. Our cases revealed abdominal pain (100%), hypertension (92%), muscle complaints (75%), a target lesion (75%), and irritability/agitation (66%) as the most common symptoms. Treatments used included antivenin, calcium gluconate, benzodiazepines, and opioids. Eight of 12 patients recovered (had relief of symptoms) within 24 hours, often by 12 hours. Antivenin did appear to bring quicker relief of symptoms. Hypertension was severe but asymptomatic in all patients. There were no complications or deaths resulting from BWSE.

This study was conducted to clarify the pathogenesis of portal vein obstruction (PVO) associated with intrahepatic stones. Five cases with PVO and intrahepatic stones were studied retrospectively. The coincidence rate of PVO in intrahepatic stones was 5.8% (5 of 86 cases), and that of intrahepatic stones in PVO, 45.5% (5 of 11 cases). All cases had one or more symptoms of cholangitis, such as high-grade fever, abdominal pain, and jaundice prior to diagnosis of PVO. The portal vein was occluded at the main trunk in 4 and in the left branch in 1. Intrahepatic stones were found in bilateral hepatic lobes in 3 and in the left lobe in 2. Numerous calcium bilirubinate stones were packed in dilatated intrahepatic bile ducts of an excised specimen of the liver. Microscopically, arterial structures could be seen, but the portal vein ceased to be evident about the involved bile duct. Based on the results of this study, persistent cholangitis and packed gallstones were concluded essential to the development of PVO accompanied by intrahepatic stones.

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.

Alendronate is an aminobisphosphonate which appears to attenuate, rather than completely inhibiting bone turnover, by suppressing the activity of osteoclasts. Clinical trials have established that 10 mg/day orally administered alendronate is the optimum dosage. Despite its poor bioavailability after oral administration, alendronate is highly effective at preventing bone loss associated with the absence of endogenous estrogen. A sustained increase in bone mass was observed during alendronate therapy without accelerated loss after withdrawal of the drug. Increased bone mass was associated with a reduction in the risk and rate of occurrence of vertebral fractures. A recent study demonstrated a 47% reduction in the risk of developing new radiographic vertebral fractures over 3 years in women with low bone mass and pre-existing vertebral fractures. There have been few direct comparisons in clinical trials. However, when compared with calcium or low dosages of salmon calcitonin (salcatonin) therapy in women with postmenopausal osteoporosis, alendronate induced a sustained increase in bone mass during therapy that was not seen with the comparator. In clinical trials alendronate was generally well tolerated when taken as recommended. Adverse events tended to be transient and usually associated with the upper gastrointestinal tract; the most common events included abdominal pain, nausea, dyspepsia, constipation and diarrhoea, which are also common with other bisphosphonates. Of potential concern are the small number of reports of patients developing oesophageal ulceration; however, this adverse event was attributed to noncompliance with the manufacturer's recommendations for administration of the drug. In addition, alendronate has not been associated with osteomalacia. Studies are still required to establish the long term efficacy of alendronate, particularly with regard to other available therapies. Although estrogen replacement therapy is generally considered the treatment of choice for the management of postmenopausal osteoporosis, many women are unable or unwilling to receive estrogens on a long term basis. Thus, alendronate, with its demonstrated beneficial effects and its good tolerability profile (when taken as recommended), is a promising alternative treatment option for the management of postmenopausal osteoporosis.

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.

Although hypercalcemia is a well-recognized complication in malignant disorders, neither the incidence and prognostic significance of hypercalcemia, nor the role of parathormone related peptide (PTHrP) in pediatric acute lymphoblastic leukemia (ALL) have been clarified. Of 83 newly diagnosed pediatric ALL patients with early pre-B cell phenotype treated at our hospital during the last 8 years, four patients were diagnosed as having hypercalcemia (> 14 mg/dl). In these 4 hypercalcemic ALL patients at onset, serum calcium levels ranged from 14.6 to 20.8 mg/dl (normal 7.4-9.0 mg/dl), and serum PTHrP levels were markedly elevated to 112-240 pmol/l (normal range: 17.6-61.2 pmol/l). Unlike patients with ordinary ALL in childhood, gastrointestinal symptoms (nausea, vomiting, abdominal pain) and skeletal symptoms (bone pain, gait disturbance) were the chief complaints. Because of these characteristic symptoms, bone marrow aspiration was carried out in two patients in an attempt to diagnose ALL before leukemic cells appeared in peripheral blood. Serum calcium levels were promptly normalized by induction chemotherapy. The four patients have been in complete remission from 35+ to 125+ months. Based on these results, the incidence of hypercalcemia in pediatric ALL patients with early pre-B cell phenotype at our institute is calculated to be about 4.8%. Gastrointestinal and skeletal problems are the characteristic initial symptoms, and hypercalcemia does not seem to be significant in the prognosis of these patients.

The disaccharide lactose is present as a natural component of foods only in milk and dairy products. In the gastrointestinal tract, lactose is hydrolysed by the enzyme beta-galactosidase (lactase) into glucose and galactose. These components are absorbed. With the exception of the caucasian race, the lactase activity decreases in most people at an age of 4 to 6 years. Lactose intake can cause symptoms of bloating, flatulence, abdominal pain, and diarrhea due to the lactose reaching the large intestine. This phenomenon is called lactose intolerance. It is generally recommended to those persons that they refrain from the consumption of milk and dairy products. However, most lactose intolerant people are able to digest small amounts of milk. They can also consume cheese that contains no (hard and semi-hard) or only small amounts of lactose (present in only 10% of soft cheeses). These products are very important sources of calcium. Compared to milk, the lactose content of yogurt is usually lower by about one third. Studies during the last 10 years have shown that in spite of its lactose content yogurt is very well tolerated by lactose intolerant persons. This advantage is ascribed to the presence of living lactic acid bacteria in fermented dairy products which survive passage through the stomach and also to the lactase present in these products.

A case report of a 50-year-old woman who has been treated with peritoneal dialysis for 9 years, with a short period off dialysis following transplantation. The patient had long-standing secondary hyperparathyroidism and had declined parathyroidectomy, she had had two episodes of peritonitis in the preceding eight years. She presented with blood-stained dialysate effluent and intermittent abdominal pain. Investigation revealed widespread peritoneal calcification with large plaques of calcium on the visceral peritoneum. She was treated with tidal automated peritoneal dialysis; adequate creatinine clearances have been maintained and the patient has had little further abdominal pain and bleeding. In this report we have illustrated an unusual complication of peritoneal dialysis, peritoneal calcification, and suggest that tidal peritoneal dialysis is a useful therapeutic tool in such cases.

Gitelman's syndrome was diagnosed in five siblings. The parents were relatives in the third remove. Gitelman's syndrome is a rare autosomal recessive hereditary magnesium reabsorption defect in the distal tubule. It is characterized by episodes of muscle weakness, usually accompanied by abdominal pain and vomiting. Tetany may occur during a febrile illness. Patients are of normal height and weight and have normal blood pressures. Sometimes eczematous skin lesions are found. Biochemically there is hypokalaemia, hypomagnesaemia and alkalosis. Urinary excretion rates of potassium and magnesium are elevated, the excretion of calcium is diminished. Treatment consists of oral suppletion of magnesium, sometimes also with oral potassium. A potassium-sparing diuretic may be used. The prognosis appears to be good.
