Metabolic alkalosis secondary to chloride depletion, especially following gastrointestinal surgery and associated with acute renal failure, is a frequent clinical occurrence. Management of the resultant acid-base disturbance mandates chloride replacement. The presence of oliguria limits the choice of accompanying cation. The use of intravenous hydrochloric acid to correct and maintain proper chloride balance, secondary to external gastric fluid losses, is recommended as a straightforward approach. Two brief case synopses are presented. Both patients, florid examples of profound chloride depletion, required large amounts of intravenous hydrochloric acid. The options regarding the choice of chloride solution, hazards involved, and a simplified schema of replacement therapy are presented. Combined gastrointestinal and renal dysfunction create unusual biochemical and clinical alterations and may result in a complex management problem.

Liver transplant is the first therapeutic choice in most of the advanced liver diseases. Nevertheless, its performance originates a number of complications derived from: a) conservation techniques of the organ (in our study a prolonged time of hot ischemia was significantly associated with); b) surgery (all patients who required massive blood transfusions developed metabolic alkalosis); c) the graft itself (all the F 1. degrees were significantly infected), and d) extrahepatic causes (cyclosporin was responsible for high blood pressure and nephrotoxicity which appeared as oliguria with good response to furosemide, as well as hyperglycemia). Some other relevant results in our series were: right pleural effusion and thrombopenia which appeared with a high incidence. Infections were usually originated the staphylococcus which grows in half of the cultures. We also want to highlight the short mean stay and the low mortality incidence in the ICU.

The first 100 liver transplantations at the Mayo Clinic were performed in 83 patients, who required a total of 917 patient days in the intensive-care unit (ICU). The mean duration of stay in the ICU was 5.91 days after liver transplantation and 6.15 days for patients who subsequently required readmission to the ICU. During the immediate postoperative period, hypothermia and hyperglycemia invariably occurred. Later during the initial admission or on readmission to the ICU, there arose the possibility of infections and renal insufficiency. Prompt diagnosis and treatment are necessary for hypertension, hypokalemia, severe metabolic alkalosis, fever, altered mental status, oliguria, and signs of graft failure in liver transplant patients. In our patient series, selective bowel decontamination minimized the occurrence of gram-negative and fungal sepsis, and use of antihypertensive agents and correction of coagulopathies may have decreased the risk of intracranial bleeding in patients with hypertension and clotting defects. Anticipation of potential conditions postoperatively and early implementation of treatment are key factors in the successful ICU management of patients who have undergone liver transplantation.

Urinary electrolytes can be a useful tool in the Emergency Department. For those patients with volume depletion, acute oliguria and hyponatremia, the determination of urinary sodium levels can aid in diagnosing the etiology of the presenting condition. Urinary potassium levels can aid the clinician in determining the cause of the potassium loss, either renal or extrarenal. For those patients with metabolic alkalosis, determination of the urinary chloride levels will allow the physician to determine if the alkalosis is chloride responsive or chloride resistant. It must be kept in mind that the measurement of any urinary electrolyte is relatively valueless unless it is interpreted with other data and/or observation of the patient. It should be noted also that a solitary value may not be adequate for making a diagnosis, and serial urinary electrolyte value assessment may be necessary. In the critically ill patient, it may be prudent to obtain a urine sample before the administration of a diuretic, the administration of potassium, or large amounts of saline. This procedure will allow for a more accurate assessment of the patient's pretreatment status.

One hundred ten episodes of renal salt retention (urinary sodium and/or chloride less than 10 mEq/L) were studied retrospectively to determine the significance of discordance of urinary sodium from chloride. In 16 episodes the urinary sodium exceeded chloride by at least 15 mEq/L. This disparity was associated with the necessity for urinary excretion of substantial quantities of poorly reabsorbed anions (penicillin, ketones, or diatrizoate), a rapidly falling serum bicarbonate level (due to resolving metabolic or developing respiratory alkalosis), or substantial renal insufficiency (serum creatinine greater than 3 mg/dL). In 14 of 110 episodes, urinary chloride exceeded urinary sodium by at least 15 mEq/L. These patients were more often oliguric and had a higher mean serum chloride than patients without this dissociation. In patients with oliguria, hyponatremia, or metabolic alkalosis, measurement of urinary sodium or chloride alone will, in a substantial number of cases, fail to detect renal salt retention. When evidence is sought for renal salt retention, both urinary sodium and chloride should be determined.

Patulin, a secondary metabolite produced by species of the genera Penicillium and Aspergillus, was administered to male Sprague-Dawley rats, weighing 50-60 g, by the oral, sc and ip routes. The 72-hr LD50 values (in mg/kg weight) were: oral, 55.0; sc, 11.0; ip, 10.0. Mortality was greatest 0-24 hr after administration by the oral and sc routes and 49-72 hr after ip dosing. Gross alterations consisted of gastric and intestinal hyperaemia and distention. Histopathological alterations consisted principally of ulceration and inflammation of the stomach. Patulin was administered orally to rats daily or every other day for 2 wk at doses of 50 or 75% of the oral LD50. Mortality in the treated groups was greater than in controls but was similar for all treated groups. No evidence of cumulative toxicity was found and the gross and histopathological alterations were similar to those found in the LD50 studies. Clinicopathological alterations included metabolic alkalosis with respiratory compensation, oliguria, decreased serum sodium, elevated blood glucose, reduced plasma protein and an elevated total leucocyte count which differential leucocyte counts indicated to be due to neutrophilia. The inflammatory alterations observed in the gastro-intestinal tract may be due to the irritant properties of patulin or to an alteration in the gastro-intestinal flora by the antibiotic activity of patulin.

A 78-year-old man was hospitalized because of muscular weakness and acute renal failure. He had been taking glycyrrhizin (280 mg/day) for the last 7 years. Hypertension was noted in his history. Serum potassium was 1.9 mEq/l with metabolic alkalosis. There was hyporeninemic hypoaldosteronism. Serum enzymes, including GOT, LDH and CPK were markedly elevated. In addition, serum myoglobin was as high as 46 micrograms/ml with massive myoglobinuria. Oliguria occurred and blood urea nitrogen and serum creatinine rapidly elevated from 20.9 to 87 mg/dl and from 1.3 to 6.7 mg/dl, respectively. Profound calcium deposition was found in the damaged skeletal muscles, including the quadriceps femoris, axillar, neck, and cardiac muscles. These results indicate that licorice-induced pseudoaldosteronism produces hypokalemic rhabdomyolysis, resulting in acute renal failure and profound deposition of calcium into the damaged skeletal and cardiac muscles.

Nephrotic syndrome, though common in children, association of it with Gitelman's syndrome (GS) is a rare occurrence. Very few cases have been reported in the medical literature so far. Here we report a case of nephrotic syndrome with frequent relapses and remissions on intermittent steroid and diuretic therapy. Patient was restarted on steroids and frusemide. Puffiness of face, bipedal edema and oliguria improved but patient developed tingling numbness in both limbs, perioral numbness and carpopedal spasm. On investigation she was found to have proteinuria, metabolic alkalosis, hypokalemia, hypocalcemia, hypomagnesemia and hyperreninemia with normal blood pressure.

We report a case of laxatives induced severe hypermagnesemia complicated with cardiopulmonary arrest. A 55-year-old woman, with nephritic syndrome and anorexia nervosa, was later transported to our emergency room (ER) because of oliguria and consciousness disturbance. During transfer to the intensive care unit from the ER, cardiopulmonary arrest suddenly occurred. Cardiopulmonary resuscitation was immediately performed, and spontaneous circulation was restored after 3 min. Thereafter, administration of dopamine, norepinephrine, and epinephrine was required to maintain systolic blood pressure at 80 mmHg. Arterial blood gas analysis showed severe metabolic alkalosis, and blood biochemical tests revealed hypermagnesemia (serum magnesium concentration, 18.5 mg/dl) and renal dysfunction. Continuous infusion of diuretics followed by massive hydration and continuous hemodiafiltration (CHDF) was started. Five days after starting CHDF, magnesium concentration was almost normalized and administration of catecholamine was stopped. It was thought that progression of renal dysfunction that occurred in the patient taking a magnesium product for chronic constipation caused reduction in magnesium excretion ability, resulting in hypermagnesemia-induced cardiopulmonary arrest. To avoid a rebound phenomenon following magnesium flux from cells, continuous blood purification seems to be an effective treatment for symptomatic hypermagnesemia.

Dehydration is a common presentation to any emergency department with symptoms ranging from lethargy, confusion, oliguria as well as those specific to the underlying cause. In this case we describe a young patient who following a short history of vomiting and abdominal pain developed carpopedal spasm and distal parasthesia on a background of Gitelman syndrome. Biochemical blood analysis showed a marked hypokalaemia, hypomagnesaemia and mild metabolic alkalosis in addition to a prolonged QTc interval of 592 ms seen on ECG. Following fluid replacement and electrolyte correction his clinical symptoms resolved along with QTc normalisation. This case demonstrates a patient with a rare and interesting renal disorder who presented with typical biochemical and ECG abnormalities in addition to tetany in the presence of normal plasma calcium.
