A 45-year-old white man ingested approximately two cups of boric acid crystals dissolved in water in a suicide attempt. Nausea, vomiting, greenish diarrhea, and dehydration occurred shortly thereafter. Two days later, he presented to the hospital with hypotension, metabolic acidosis, oliguric renal failure, a generalized erythematous rash, and several superficial skin abrasions. His condition failed to improve despite intravenous fluids and vasopressors. He later developed atrial fibrillation with a rapid ventricular response and could not be converted to a sinus rhythm. This rhythm deteriorated to electromechanical dissociation, and the patient died 17 hours after admission. The urine and whole blood boric acid concentrations approximately 52 hours after ingestion were 160 and 42 mg/dL, respectively. These results are equivalent to urine and blood boron concentrations of 28 and 7 mg/dL, respectively. A postmortem urine boron concentration was 29.4 mg/dL. The autopsy report listed boron toxicity as the cause of death. This is the only adult reported to die from acute boric acid ingestion in recent years and may be atypical since the patient was untreated for 3 days and presented with dehydration and renal function impairment. This case suggests that lack of adequate urine flow and dehydration increases the risk of boron toxicity.

An outbreak of municipal water-associated food poisoning by Salmonella Enteritidis occurred in Takatoh Town. Nagano prefecture during September 4 to 19, 1989. The major symptoms observed in the 680 patients consisted of diarrhea (70.9%), abdominal pain (51.2%), fever (44.6%), headache (27.9%), nausea (5.9%) and vomiting (5.7%). In the outbreak, S. Enteritidis was the only suspected etiological agent isolated from both patients and municipal water supply. All of the 21 isolates were lysine decarboxylase activity negative. In other respects, the isolates conformed to the general characteristics of Salmonella. All of them were further characterized by phagovar 8 type, uniform drug susceptibilities and carrying 2.7 kb plasmid. Inspite of the evidence that the infection caused by a peculiar strain linked to the strain in municipal water supply used by the patients, it was impossible to determine the exact source of contamination in the water. The outbreak above seems to be the most large-scale among those of Salmonella found poisoning associated with drinking water in Japan.

Forty-eight dogs were separated into four groups of six males and six females. Acrolein (0.1% aqueous) was administered in gelatin capsules to three of these groups at dosing levels of 0.1, 0.5 and 1.5 mg kg-1 day-1 based on results of a range-finding study. After 4 weeks, the high dose was increased to 2 mg kg-1 day-1. The fourth group received deionized water in the same number of gelatin capsules as the high-dose group. Dosing was 7 days per week for 53 weeks. Blood and biochemical measurements were made pretest and at 3-month intervals thereafter. At termination, all dogs were subjected to full necropsy and histological examination. The major test effect noted was frequent vomiting after dosing. This was observed to be dose-dependent and the frequency decreased with time, indicating an adaptive effect. One mid-dose female died during the test and was diagnosed as having died of severe bronchial pneumonia, probably a result of vomitus aspiration. Serum albumin, calcium and total protein values were depressed in high-dose animals throughout the study. Some variability in red blood cell parameters and coagulation times were noted but the significance of these effects was not obvious.

Cholera is a diarrheal disease that results from colonization of the small intestine by the Vibrio cholerae organism. The disease is spread primarily by means of fecal contamination of drinking water and may begin with the sudden onset of profuse, watery diarrhea. Vomiting, rapid dehydration, acidosis, muscular cramps and circulatory collapse are other prominent features of severe cholera. Diagnosis is confirmed by identification of the organism in a stool specimen. Treatment requires immediate replacement of the massive fluid loss before diagnostic studies are ordered. Clinicians should suspect cholera in any case of massive, shock-producing diarrhea, especially if the patient has traveled to a cholera-affected country. This article presents epidemiology and public-health measures, pathophysiology, diagnosis, clinical signs and symptoms, and treatment modalities for adults and children infected with the V. cholerae organism.

This study was undertaken to determine the dosages, treatment times and side effects of ketamine HCI with and without two benzodiazepines when used for sedation on a group of precooperative children at the UCLA Children's Dental Center. Ketamine was evaluated when used alone, and in conjunction with two benzodiazepines, diazepam or a new water-soluble midazolam. An anti-muscarinic, atropine or glycopyrrolate, and nitrous oxide-oxygen were included in all sedations. Mean treatment times were increased significantly when ketamine and a benzodiazepine were used in combination. Additionally, mean ketamine dosages were decreased significantly when ketamine was utilized in combination with a benzodiazepine. All children tolerated the sedation well and there were no severe adverse reactions. Side effects included nausea, vomiting, and a rise in post-operative temperatures.

To obtain accurate, timely data on the health status of persons in evacuation camps after the eruption of the Mt. Pinatubo volcano, the Philippine Department of Health (DOH) conducted a survey of the health needs of the evacuees and established disease surveillance in each camp. Surveys of the camps revealed that sources of potable water, sanitary means of waste disposal, and shelters were inadequate. Disease surveillance showed that measles, acute respiratory infections, and diarrhea were the most important problems. Surveillance detected outbreaks of measles and an outbreak of vomiting and diarrhea in the camps. Deaths, primarily caused by measles (31%), diarrhea (29%), and respiratory infections (22%), totaled 349 in the first 12 weeks. Death rates peaked in the seventh week, when a death rate of 26/10,000 occurred among the Aetas, a tribe evacuated from the slopes of the volcano. The surveys guided the DOH in allocating supplies and medicine, while disease surveillance enabled disaster managers to monitor the effectiveness of health programs, identify high-risk groups, and respond appropriately to the situation.

A 32-year-old man was diagnosed as having pseudo-Bartter syndrome due to surreptitious habitual vomiting and to maldigestion related to decayed teeth. His chief complaints were muscle pain and weakness. In this case, metabolic alkalosis, hypokalemia, hypochloremia, increased plasma renin activity and aldosterone levels were noticed with marked decreases in urinary chloride excretion. Creatinine clearance (GFR) and renal plasma flow (RPF) were also decreased. Blood pressure was normal, but the pressor response to angiotensin II was attenuated. Before treatment with 0.9% saline infusion, plasma vasopressin (AVP) was not suppressed sufficiently by lowering the plasma osmolality (Posm) with an oral water load (WL), but it normally responded to a rise in Posm due to hypertonic saline infusion. Moreover, plasma AVP was normally suppressed by WL after the replenishment of saline. Plasma atrial natriuretic peptide (ANP) was low before WL, but increased normally in response to WL. However, inconsistent with the normal response in this case, decreases in plasma AVP failed to dilute urinary osmolality and to increase urine flow, irrespective of the levels of plasma ANP. These results indicate that chronic inanition due to surreptitious vomiting causes impaired renal diluting ability through decreases in GFR and RPF, irrespective of the levels of plasma AVP and ANP.

Totally-enclosed motor-propelled survival craft (TEMPSC) are used to evacuate the crews of mobile offshore drilling units in emergencies. The small size and flat bottom of the TEMPSC predispose most occupants to seasickness, even in relatively calm waters. This paper discusses efforts required to improve the well-being of occupants in terms of reducing seasickness, dehydration, hypothermia, anxiety, and the other factors that contribute to loss of comfort and the will to survive. Specific recommendations include the provision of climatic control to regulate temperature, remove odors and provide fresh air; potable water, electrolytes, and survival rations; and an ample supply of motion sickness bags. Overcrowding should be avoided. Anti-motion-sickness drug therapy to control vomiting should be administered in two ways: initial injection of intramuscular scopolamine for fast action followed by a transdermal ear patch for long-term protection. Leadership and seasickness management should be requisite survival training for all oil rig workers.

A combination of metoclopramide, dexamethasone, droperidol, lorazepam, and diphenhydramine was used in prophylaxis of high-dose (greater than or equal to 100 mg/m2) or moderate dose (greater than or equal to 50 mg/m2) cisplatin. Sixty minutes prior to starting cisplatin, 16 mg dexamethasone, 50 mg diphenhydramine, and 0.5 mg lorazepam were given orally (PO). Droperidol 1 mg was given intramuscularly (IM) 15 minutes prior to beginning cisplatin. Repetitive doses of intravenous (IV) metoclopramide, 2 mg/kg in 75 ml 5% dextrose in water over 15 minutes was given 30 minutes prior to, and at 1 1/2, 4 1/2, and 7 1/2 hours after beginning cisplatin chemotherapy. Only patients with nausea and/or vomiting received subsequent doses of 2 mg/kg metoclopramide IV every 3 hours as needed. Patients refractory to metoclopramide were given 1 mg droperidol IM and 50 mg of diphenhydramine PO every 6 hours. There were 19 men and 9 women with a median age of 58 (range 31-75) years. Complete protection from nausea and vomiting in all courses of treatment occurred in 17 (61%) patients. In 63% and 70% of the 57 evaluable courses, there was neither nausea nor vomiting, during the first 24 hours after cisplatin. When present, nausea was mild and the median number of vomiting episodes was 2 (range 1-3). This antiemetic regimen was well tolerated. Toxicities were mild and occurred in 3 patients (angioneurotic edema, transient episode of facial twitching, and heaviness of tongue, respectively). The 5-drug antiemetic combination can prevent cisplatin-induced nausea and vomiting in a majority of patients.

Beagle dogs were allocated to 4 groups, each consisting of 3 males and 3 females, which received 0.055, 0.165 or 0.495 mg paraquat (PQ)/kg/day sc for 4 w to investigate subacute toxicity. Recovery 4 and 8 w postadministration was studied. In the early stage there was vomiting, decreased activity and undernourishment. Induration and ulcers at the injection sites were seen. The group receiving 0.495 mg PQ/kg had reduced food ingestion and occasional decreases in water consumption until the end of the 4-w injection period. Three animals in the 0.495 mg PQ/kg group were sacrificed in the moribund stage with marked decreases in body weight. Ophthalmologic examination at 4 w of recovery detected hemorrhage around the nasalis vein of the left fundus in 1 animal that received 0.495 mg PQ/kg. No abnormal changes in electrocardiography (ECG) were noted throughout the experimental period. Slightly increased urinary protein, reticulocyte counts, and fibrinogen were observed in a few animals in each group. A few animals that received 0.165 or 0.495 mg PQ/kg had increased phospholipid, blood urea nitrogen, and creatine phosphokinase. The lungs of the moribundly sacrificed animals had moderate atelectasis, localized atelectasis, moderate thickening of alveolar wall and pleura, proliferation of fibroblast-like cells, and abundant fibers in interstitium and alveoli. In the liver there was slight hemorrhage along the gallbladder. On electron microscopy of the lung, proliferation of fibroblasts, myofibroblasts and type II alveolar cells, and some mast cells were observed in thickened alveolar walls. Abundant collagen fibers, destroyed cell debris and mitotic figures of spindle-shaped fibroblasts were also observed in the dilated interstitium.(ABSTRACT TRUNCATED AT 250 WORDS)
