Classic renal tubular acidosis is characterized by a primary defect in establishment of a large hydrogen ion gradient across the distal renal tubule. Thus the development of hyperchlorenic metabolic acidosis follows. In addition, hypokalemia results from renal potassium wasting secondary hyperaldosteronism from sodium wasting and contraction of the extracellular fluid. The presenting signs and symptoms are growth retardation, fatigue, periodic paralysis, polyuria, polydipsia, vomiting and constipation as well as nephrocalcinosis and nephrolithiasis. It is suggested that effective treatment with alkali therapy requires markedly higher doses than formerly recommended, and may related to a higher rate of endogenous acid production from (1) intermediary metabolism of sulfur amino acids and organic acids, (2) impaired tubular reabsorption of bicarbonate and (3) hydrogen ion release from hydroxyapatite formation. It is also suggested that acidosis may interfere with vitamin D metabolism and thus play an important role in the pathoetiology of the growth failure in children with this disorder.

Anorexia, constipation, vomiting and somnolence in a 39-year-old woman were at first misinterpreted as being of psychological and autonomic nervous system origin. Further clinical and biochemical tests revealed hyperthyroidism associated with hypercalcaemia and hypercalciuria. Thyrostatic treatment for 12 days caused regression of the hypercalcaemia and, after subtotal resection, serum calcium levels and urinary calcium excretion returned to normal for good. The hypercalcaemia syndrome must therefore be assumed to have been the direct result of the hyperthyroidism.

St Christophers' Hospice near London is now internationally known as a special centre for the care of terminally ill patients. In these cases, the relief of symptoms is paramount, and prominent among those symptoms is pain. Such pain can almost always be relieved without euphoria or lessening of consciousness. More than 60% of patients admitted to St Christopher's complain of pain, and the scheme of management outlined below results in substantial or complete relief of pain in all of them. Addiction does not occur when control of the patient's pain is part of the pattern of total care. The author considers management of pain of varying severity, together with associated symptoms such as vomiting, anorexia, dry mouth and hiccup, dyspnoea, cough, anxiety and depression, insomnia, constipation and diarrhoea.

Cow's milk allergy was diagnosed in 79 patients, all of whom had signs and symptoms of allergies other than milk intolerance. In addition to difficulties with infant feeding and diarrhoea, clinical features included constipation, vomiting, intestinal colic, growth retardation, and psychological disturbance, as well as eczema and asthma. All were reversible after milk withdrawal, which suggests that the allergic basis of such symptoms may have been underestimated. In most cases, one or both parents were atopic and the child had been bottle-fed from birth. There were no breast-fed children of non-atopic parents in this series.

The effect of guancydine (1-cyano-3-tert-amylguanidine) on systemic and renal hemodynamics was studied in nine patients with arterial hypertension. Antihypertensive drugs were withheld for 15 days before beginning the investigation. Average sodium intake was 105 meq/24 hours in some patients and 25 meq/24 hours in others. Patients received placebo during a control period that averaged 14 days. Guancydine was given for 7 to 18 days at an average dose of 21 mg/kg of body weight. Although mean arterial blood pressure decreased significantly in all patients, it reached normal levels in only two. There was no change in cardiac output. Glomerular filtration rate and renal plasma flow remained unchanged, whereas urinary sodium excretion diminished, suggesting an activation of the renin-angiotensin-aldosterone system. A substantial gain in body weight was noted. Nausea, vomiting, constipation, somnolence, restlessness, mental confusion, asthenia, and urine retention were observed. The anti-angiotensin effect of guancydine that has been described in animals was not observed.

Proprietary sleep aids and sedatives can cause delirium, coma and occasionally death in children and adults. The constituents in sleep aids that significantly effect central nervous system activity are bromides, methapyrilene, pyrilamine and scopolamine (hyoscine). Constituent proportions and mixtures vary greatly at different times since manufacturers make frequent adjustments. The effects of toxicity resulting from the misuse of ethylenediamines include nausea, vomiting, blurred vision, incoordination, tremors, dry mouth, constipation and an acute poisoning syndrome. Management of adverse reactions produced by either methapyrilene or pyrilamine consists of dosage reduction or discontinuation. The acute poisoning syndrome requires implementation of general symptomatic and supportive principles.

Difficulties arise in the interpretation of liver tests in the pregnant subject, since some values increase (alkaline phosphatase) whilst others remain unchanged (transaminases) or fall during pregnancy. The diagnosis and management of some causes of jaundice in pregnancy, such as viral hepatitis, gall stones, benign intrahepatic cholestasis and acute fatty liver of pregnancy are discussed. Little is known about the commonest symptoms of pregnancy (nausea, vomiting and constipation) other than that they might be due to hormonally induced alteration of sphincter tone. However, pre-existing bowel disease has a greater effect on pregnancy. Fertility is reduced in poor nutritional states (e.g. coeliac and Crohn's diseases) and an increased occurrence of spontaneous abortion has been noted. For inflammatory bowel diseases, the time of onset is important in determining the outcome of pregnancy. Relapse in the disease is commonest in the first trimester and in the puerperium. Treatment of these conditions is essentially as in the non-pregnant subject. The controversial subject of sulphasalazine and steroid usage in pregnancy is discussed.

A case report of subacute, reversible ischemic colitis associated with use of oral contraceptives (OCs) is reported. A 19-year-old woman was admitted to the hospital with chief complaints of abdominal cramps, nausea, vomiting, diarrhea, and rectal bleeding of 2 days' duration. Past medical history and family history were noncontributory. The patient was receiving no medication other than Norinyl 2 (2 mg of norethindrone and .1 mg of mestranol), which she had been taking for 6 months. 2 days before admission the patient had taken 100 mg of dimenhydrinate and 2 ExLax tablets (90 mg of phenolphthalein) for constipation. Colonic roentgenograms revealed impaired mesenteric circulation and bowel ischemia; OC-induced ischemic bowel disease was diagnosed. Patient symptoms subsided within 96 hours of discontinuing the OC and initiating supportive therapy (including intravenous fluid infusion, nasogastric suction, analgesics, and antiemetics). When a repeat barium enema was performed, it showed resolution of the ischemia. In a short review following the case report, these drugs were indicted in causation of colitis-like syndrome: amoxicillin, ampicillin, cephazolin, chloramphenicol, chlorpropamide, clindamycin, cloxacillin, cotrimoxasole, cyclophosphamide, digitalis, ergotamine tartrate, flucytosine, fluorouracil, gold salts, laxative and cathartic abuse, mercurous chloride, methyldopa, penicillin V, and tetracycline. Ischemic bowel disease secondary to OC use is a rare but important complication because of its significant morbidity and potential mortality, and because of the widespread use of the drugs. The case report emphasizes the need to consider the differential diagnosis of acute vascular insult with bowel ischemia when acute abdominal pain progressing to bloody diarrhea occurs in young women taking OCs.

In a 54-month retrospective review, we compared the clinical features of 26 narcotic addicts with staphylococcal endocarditis (group 1) and ten other addicts with nonstaphylococcal endocarditis (group 2). The admission temperature and the respiratory rate of patients in group 1 were significantly higher (P less thn .05 and less than .02 respectively) than those of patients in group 2. Group 1 also differed from group 2 in the following variables: (1) bilateral multiple pulmonary infiltrates in 46% vs none in group 2; (2) greater incidence of symptoms referable to the central nervous system (50% vs none in group 2); and (3) gastrointestinal symptoms of vomiting, diarrhea, or constipation in 62% vs 10% in group 2. Serious cardiovascular, renal, and other complications were more frequent in staphylococcal endocarditis. Tricuspid regurgitation occurred with equal frequency in both groups and was of no value in differentiating staphylococcal from nonstaphylococcal endocarditis.

Chronic idiopathic intestinal pseudoobstruction (CIIP) is a disorder of alimentary tract motility with onset of symptoms in adolescence or young adulthood, characterized by recurring attacks of abdominal pain, distention, vomiting, and constipation often leading to malnutrition and death. Starting with an adolescent patient, treated for a succession of life-threatening attacks of pseudoobstruction, the authors have identified CIIP in four generations of a Virginia family. Studies show characteristic dilation and diminished motility of the esophagus and intestine. Surgery's role in CIIP is palliative, and operation should only be offered when medical measures have failed to control symptoms.
