Metrizamide is a nonionic water-soluble contrast medium for neuroradiological studies that is less irritating to the nervous system than other water-soluble agents. Studies in adults have shown that metrizamide has advantages over currently available media, but experience with children has been limited. Sixty-two children have had myelography or ventriculography using metrizamide. The children ranged in age from 11 days to 22 years. Technically satisfactory studies were obtained in every patient. No major complications were encountered. Minor side-effects included headache in 11 children (18%), mild nausea or vomiting in 16 children (26%), and fever in 4 children (6%). Seizures did not occur. One infant in the study subsequently died of unrelated problems; there was no evidence of arachnoiditis at postmortem examination. Metrizamide is a safe, effective contrast medium for neuroradiological use in children.

Radiographic quality as well as adverse effects of intrathecal metrizamide instillation was prospectively investigated in thirty-three clinical cases admitted to the department of neurosurgery, University of Tokyo Hospital, and Kantoh Teishin Hospital. Metrizamide CT cisternography was performed in fifteen cases using in most cases 10 ml of 170 mg I/ml solution through lumbar route. Eleven cases exhibited "normal" pattern CSF circulation and the remaining four, "delayed" pattern. Eight cases (53%) experienced headache, nausea, and/or vomiting several hours after the instillation. All of these belong to the "normal" pattern group. Four cases of "normal" pattern received electroencephalographic examinations before and after metrizamide instillation. Three revealed appearance of negative spike and slow wave burst or sharp waves one to twenty-four hours after the instillation, along with penetration of metrizamide into brain parenchyma. Diagnostic quality was interpreted as "good" in eleven cases. Small acoustic neurinoma, pituitary adenoma, arachnoid cyst, and subdural hygroma were diagnosed among others. Metrizamide ventriculography was done in four cases. No untoward effect of significance was attributed to metrizamide per se. Cervical myelograpy and/or CT myelography was done in fourteen cases using, in most cases, 10 ml of metrizamide 170 mgI/ml. Polytome tomography with metrizamide instillation through lateral cervical puncture was highly diagnostic, whereas, ordinary X-ray with lumbar instillation yielded less satisfactory results. CT myelography in cases of subarachnoid block required good consideration on instillation site and positioning of the patient. Six cases (50%) among twelve cases where metrizamide had run into the cranial cavity experienced headache, nausea, and/or vomiting to a lesser degree than those of cisterno graphy. Metrizamide is the first contrast agent ever made which can be safely introduced into human subarachnoid space, if administered judiciously, nervous. However, metrizamide is weakly toxic to central system and provokes minor untoward effects as well as electroencephalographic abnormalities and, sometimes, clinical convulsive seizure. It would be wiser to restrict the dosage of metrizamide in cisternographic study, expecially in cases of "normal" pattern CSF circulation, to 1.2 gI or 7 ml of 170 mg I/ml solution. Routine use of X-ray cisternography should thus be discouraged because it needs higher concentration of metrizamide in the intracranial cisterns.

The presentation, nonradiologic diagnostic evaluation, and course (including complications and outcome) of gastrointestinal disorders in pregnancy are not substantially different than for the nonpregnant patient. The possible exception is the higher mortality for pancreatitis when it occurs during pregnancy. With the exception of nausea/vomiting and hyperemesis gravidarum, there does not appear to be a gastrointestinal tract disorder that is peculiar to the pregnant state. Hepatic disorders are somewhat different in that the excretory defect-pruritus gravidarum-cholestatic jaundice spectrum and perhaps part of what presents as acute hepatic failure are intimately associated with pregnancy and have an onset and course that are tied to the gestational period. Otherwise, hepatic diseases that occur during pregnancy share the characteristic of gastrointestinal diseases, that their manifestations are not clearly different from the nonpregnant state. As is true for the diagnostic approach to all medical diseases that occur during pregnancy, radiographic procedures are prohibited. Furthermore, therapy must be reconsidered with concern for its effect on the fetus. This leads to elimination of many or all measures used for purely symptomatic or nonspecific benefit. If no harm or potential harm will accrue for the fetus, therapy for hepatic and gastrointestinal disorders preceeds in pregnancy very much as it does in the nongravid individual.

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.

In June and July 1975, Gastrointestinal illness occurred in more than 200 staff members and 2000 visitors to an American national park. In was characterized by prolonged diarrhea, cramps, nausea, and vomiting, lasted a median duration of 8 days, and was significantly associated with consumption of park water (P less than 0.001), which had been contaminated by raw sewage. Enterotoxigenic Escherichia coli serotype 06:K15:H16 was isolated from 20 of 49 ill park residents and from the park's water supply, but not from 71 residents who had never been ill or had been well for at least 4 days. No other bacterial, viral, or parasitic pathogens were isolated from ill or well persons. This outbreak is the first waterborne epidemic of diarrheal illness shown to be due to enterotoxigenic. E. coli, and this study documents one mode of transmission of this pathogen. This investigation also suggests the relative insensitivity of current methods for identifying persons infected with this organism, either by the culturing of randomly selected isolates or by measuring serologic responses.

A double-blind comparison of the efficacy and safety of droperidol (5 mg), hydroxyzine HCl (50 mg), diazepam (5 mg), and saline placebo, given concomitantly with meperidine (50 or 75 mg) for preoperative medication, was conducted in 280 female patients scheduled for minor gynecologic procedures. Droperidol proved to significantly superior to the other study drugs in alleviating apprehension (83% of patients calm versus 54, 46, and 34% for hydroxyzine, diazepam, and placebo, respectively). Some drowsiness, occurred in 68 percent of the droperidol-treated patients versus 31, 30, and 21 percent of the other 3 groups, respectively. Global evaluations were consistent with these findings. No clinically significant changes were observed in vital signs in any of the study-drug groups. Adverse reactions were unremarkable in all groups. Significantly less nausea occurred with droperidol than with other treatments, and signficantly less vomiting occurred with droperidol or hydroxyzine. Significantly fewer patients in the droperidol group than in the diazepam group required postoperative antiemetics.

A double-blind comparison was undertaken between Debendox with 10mg of extra pyridoxine and placebo with 10mg of pyridoxine, in 56 women suffering from nausea and/or vomiting during the first 10 weeks of pregnancy. The results of treatment were assessed on the patient's own dialy records of:the time of nausea, the frequency of nausea, and the severity of nausea, retching and vomiting. There were statistically significant differences in favour of Debendox with extra pyridoxine in respect of the days of nausea all day (P les than 0-02), the severity of nausea (P less than 0-05) and the severity of retching (P less than 0.05).

Alkaline gastritis and alkaline esophagitis are now precisely defined syndromes. They occur most often after gastric surgery in which function of the pyloric and lower esophageal sphincter is compromised. Reflux of bile in these patients can then lead to severe inflammation of the gastric and lower esophageal mucosa. Epigastric pain, nausea and bilious vomiting are characteristic symptoms. Gastroscopy with biopsy is, therefore, the definitive diagnostic test; during endoscopy bile is seen in the lower esophagus or stomach, and the mucosa is red, friable and contains acute erosions. Conservative therapy including the administration of cholestyramine has not been helpful. Surgery consisting of diversion of the duodenal contents away from the stomach and lower esophagus is the treatment of choice. The Roux-en-Y procedure has been used most often and has resulted in the amelioration of the symptoms and signs in most patients.

A multicentre trial was conducted to compare Lomotil and Imodium in the treatment of acute non-specific diarrhoea in general practice. A total of eighty-three patients contributed to the study and were randomly allocated to one of the two treatments. No statistically significant differences were found betwwen the drugs in their efficacy and speed of action in alleviating diarrhoea or in their palliative effect on nausea/vomiting and abdominal pain when present.

Bile acids have been proposed to be important in the pathophysiology of the syndrome of "bile reflux gastritis" after surgery. To examine the role of cholestyramine, an ion exchange resin that binds bile acids, on symptoms of this syndrome, we did a randomized, double-blind crossover study on 16 patients. No differences in frequency of abdominal pain, nausea, vomiting, or bitter taste were observed among cholestyramine (4 g, three times daily for 3 weeks), placebo, and routine (dietary restriction and ad libitum antacid) treatment periods. We conclude that this regimen of cholestyramine was ineffective in symptomatic treatment of bile reflux gastritis.
