2 AIDS patients are described who had cryptococcal meningitis accompanied by increased intracranial pressure (ICP) and visual complications, a finding thought to be relatively rare in AIDS. Of the 2-6% of AIDS patients who develop cryptococcal meningitis, many have disseminated and recurrent infections. The 1st case was a 45-year old Ugandan woman who presented with stiff neck, and right VIth cranial nerve palsy. She was treated with amphotericin B and flucytosine with some improvement, but on the 9th day she awoke with headache, drowsiness, and total blindness, although no papilledema. Her CSF pressure was 40 cm H20. She recovered after a month of intravenous chemotherapy and acetazolamide, but remained blind. Her sudden blindness was thought to be due to bilateral optic nerve infarction. The 2nd case was a 32-year old male homosexual, admitted with headache, vomiting, confusion, and drowsiness. He had stiff neck, and a CSF of 40 cm containing Cryptococcus neoformans. He was given amphotericin B, flucytosine, and has CSF drained every other day. On day 21 papilledema was seen in the right eye, and acetazolamide was started to lower CSF pressure. This patient recovered without loss of vision. 3 published series of cryptococcus meningitis in AIDS patients remarked about the low incidence of raised ICP, while 1 reported 9 of 27 with neurological and ophthalmic complications. The visual complications and increased ICP in these patients was thought to be due to inflammatory arachnoiditis or direct cryptococcal infiltration.

We report a series of 5 representative patients in California who experienced adverse reactions from the illicitly marketed substance gamma-hydroxybutyrate (GHB). The drug is a putative neurotransmitter marketed as a growth hormone releaser for bodybuilders. The most commonly reported symptoms included abrupt drowsiness, dizziness, and a "high". Other effects were headache, nausea, vomiting, myoclonic jerking, and short-term coma. There have been no reported deaths. If product use is discontinued, full recovery with no long-term side effects is universal. No clear dose-response effect was observed; this may be attributable to differences in susceptibility, wide variations in doses taken by the same person, or the coingestion of other substances. Case interviews confirm that, despite being banned by the US Food and Drug Administration, GHB is still widely available in the underground drug market. Athletes and bodybuilders may take drugs for which there are claims of improved performance or body image. Physicians should be alert for signs of GHB poisoning in emergency department and clinic patients.

This is the first study in children from the United States that evaluates the immunogenicity of and adverse reactions to the Connaught/Biken two-component acellular pertussis vaccine compared with whole-cell pertussis vaccine when given as a primary immunization series at 2, 4, and 6 months of age. Three hundred eighty infants were studied; 285 received acellular diphtheria-tetanus toxoids-pertussis (DTP (ADTP)) and 95 received whole-cell DTP (WDTP). Following the third dose, ADTP vaccination produced higher antibody responses than WDTP to lymphocytosis-promoting factor (enzyme-linked immunosorbent assay IgG geometric mean titer (GMT) = 131 vs 9 and Chinese hamster ovary cell assay GMT = 273 vs 16) and to filamentous hemagglutinin (IgG GMT = 73 vs 10) (all P less than .0001). Agglutinin responses were higher in WDTP compared with ADTP recipients (GMT = 50 vs 37; P = .02). Local reactions were fewer for all three doses following ADTP vaccination. Fever, irritability, drowsiness, anorexia, vomiting, and unusual crying all occurred less frequently in ADTP compared with WDTP recipients for one or more of the three doses. We conclude that this two-component ADTP vaccine when given as a primary series produces greater immunogenicity and fewer adverse effects than the currently licensed WDTP vaccine.

A prospective study of late adverse reactions to nonionic contrast media was conducted in 2,382 patients who underwent computed tomography (CT). Late reactions were defined as those that occurred more than 30 minutes but within 2 days after completion of CT. The overall rate of late reactions was 8.0% (165 of 2,052 patients), which was greater than the rate of immediate reactions (3.8% [90 of 2,382 patients]). Headache and rash were the most frequent manifestations. Three patients experienced severe vomiting, heavy drowsiness, or oliguria and required medical attention. Late reactions occurred more frequently in female patients, younger adults, and patients with histories of allergic reactions. This investigation shows that although late adverse reactions to nonionic contrast agents are not life threatening, these reactions are not uncommon. It is important that radiologists recognize these late reactions. Patients and referring physicians should be informed that late reactions can occur and may require medical attention.

Limited toxicity information is available in the medical literature on the antidepressant fluoxetine (Prozac, Dista Products Co, Indianapolis, IN). The goal of this prospective multicenter study was to develop a toxicity profile of initial signs and symptoms observed in an acute fluoxetine overdose. A prospective study was made of patients reported to one of four American Association of Poison Control Centers' regional poison control centers after ingesting an acute overdose of fluoxetine. A standard data collection form was used on all patients ingesting fluoxetine. Information obtained included age, current medications, dose, coingested drugs, presenting symptoms, vital signs, electrocardiogram abnormalities, outcome, and fluoxetine levels. The authors collected 272 cases; 234 cases met the criteria of the study. Fluoxetine was ingested alone in 87 cases and with ethanol or other drugs in the remaining 147 cases. Of the 87 cases where fluoxetine was ingested alone, 67 patients were adults and 20 were children. Symptoms that were seen in the adult group included: tachycardia (15/67), drowsiness (14/67), tremor (five/67), vomiting (four/67), or nausea (four/67). Thirty patients did not develop symptoms. Twelve of the adult overdose patients had total fluoxetine levels ranging from 232 to 1390 ng/mL. The authors conclude that symptoms that develop after an acute overdose of fluoxetine appear minor and of short duration. Aggressive supportive care is the only intervention necessary.

Diarrhea is a common gastrointestinal problem in diabetes, and its prevalence has been underestimated. The cause of diabetic diarrhea is unknown, but it is probably related to gastrointestinal motility disturbances secondary to diabetic autonomic neuropathy. Other causes (especially primary malabsorption syndromes and islet cell tumors) must be excluded. Treatment of diabetic diarrhea is largely symptomatic and only moderately effective. Antidiarrheal agents may ameliorate acute episodes. Broad-spectrum antibiotics and clonidine hydrochloride (Catapres) have had some success in long-term control. Most recently, subcutaneous administration of somatostatin analogues has been shown to be helpful, the main side effects being drowsiness and vomiting.

The clinical spectrum of toxic effects and serum concentrations after ingestion of carbamazepine were studied in 82 pediatric patients. Serum carbamazepine level was related to the depth of coma (p less than 0.001), convulsions (p = 0.002), hypotension (p less than 0.001), and the requirement for mechanical ventilation (p less than 0.001). In 10 patients in deep coma with a Glasgow Coma Scale (GCS) of 3-4, the mean serum level was 213 mumol/L (range 143 to 343); seizures, ventilatory failure, or hypotension caused by myocardial failure and conduction defects were observed. In four of these, large doses of inotropic agents were required, one patient was treated with plasmapheresis, and two died--one of cardiac failure and one of aspiration pneumonitis. In 27 patients with moderate coma (GCS 5-8), the mean serum level of carbamazepine was 112 mumol/L (range 63 to 176); convulsions were observed in two patients in this group. In 45 patients whose conscious state was mildly depressed or normal (GCS 9-15), the mean serum level was 73 mumol/L (range 37 to 128); additional effects were drowsiness (80%), ataxia (53%), nystagmus (38%), vomiting (17%), and dystonia (7%). I conclude that patients with serum carbamazepine levels of approximately 100 mumol/L require close observation, whereas those with levels greater than 150 mumol/L may require intensive life support.

A randomized, double-blind study was designed to determine the effects on maternal intraoperative analgesia of adding one of the following opioids to the local anesthetic at the onset of epidural block, before surgery and neonatal delivery: morphine (3 mg), fentanyl (75 micrograms), sufentanil (50 micrograms), buprenorphine (0.3 mg) and oxymorphone (1 mg). The duration of postoperative analgesia, the presence of side effects and the neonatal outcome were also studied. Ninety healthy multiparas, at term, undergoing elective cesarean delivery using lumbar epidural anesthesia with 2% lidocaine were randomized in six equal groups to receive one of the opioids or saline. The predelivery administration of morphine, fentanyl and sufentanil significantly improved the intraoperative analgesia. Patients who received fentanyl, sufentanil, buprenorphine or oxymorphone had more somnolence than the others (p less than 0.01), but this did not interfere with the first mother-infant relationship during surgery. Patients in the buprenorphine group had more vomiting during surgery when compared with the others (p less than 0.01). Morphine provided the longest pain-free interval, followed by oxymorphone, buprenorphine, sufentanil and fentanyl. Postoperatively, the number of patients having pruritus and vomiting was significantly higher in the morphine and buprenorphine groups, respectively (p less than 0.01 versus others). No adverse neonatal effects were noted in any group.

A 2.5-year retrospective study of pyogenic meningitis in hospitalized children in Kelantan was carried out with regard to aetiology, clinical features, investigation, treatment and outcome. There were 58 children with 43 cases (74.1%) occurring below the age of 1 year. Frequent presenting symptoms included fever (98.3%), fits (77.6%), anorexia (39.7%), vomiting (34.5%) and drowsiness (12.1%). On admission, 37 (63.7%) had neck stiffness, 10 (17.2%) had Kernig's sign and 32 (55.2%) had coma. CSF cultures were positive for Haemophilus influenzae in 29 (50%), Streptococcus pneumonia in 13 (22.4%) and Neisseria meningitidis in 3 (5.2%). The antibiotic sensitivity profiles showed that the three main organisms were 100% sensitive to Chloramphenicol, Streptococcus pneumoniae was 100% sensitive to penicillin, Neisseria meningitidis was 100% sensitive to penicillin and ampicillin, and Haemophilus influenzae was 90% sensitive to penicillin and ampicillin. The total hospital mortality was 18.9%. All but two of the eleven deaths occurred in children younger than 1 year. Nineteen of the 35 (54.3%) survivors attended for at least one follow-up after discharge from hospital. Of these 19 children, 47.4% had neurological sequelae.

The aim of the study was to assess vomit and pain control in terminal cancer patients with inoperable gastrointestinal obstruction, using a pharmacologic symptomatic treatment which prevents recourse to nasogastric tube placement and intravenous hydration, in hospital and home care settings. Twenty-two symptomatic patients, who were judged as inoperable, were treated with a pharmacologic association of morphine hydrochloride and scopolamine butylbromide as analgesics and haloperidol as an antiemetic. The drugs were administered by continuous subcutaneous infusion via a syringe driver or intravenously only when a central venous catheter had been inserted previously. Daily recordings included assessment of pain, number of vomiting episodes, dry mouth, drowsiness, and thirst sensation. Data were examined before starting the treatment (T0), 2 days after (T2) and 2 days before death (T-2). They showed that there was a significant decrease in the pain score (p less than 0.001) on T2 and a further decrease on T-2 (p less than 0.05). Vomiting was controlled in all patients, with the exception of three patients with upper abdomen obstruction who required nasogastric tube placement. Dry mouth showed an upward trend throughout the observation period (p less than 0.05) but was successfully treated by administering liquids by mouth or ice-cubes to suck. Drowsiness too presented an upward trend from T0 to T-2 (p less than 0.001). Only one patient out of 16 who reported to be thirsty required intravenous hydration. We believe that in terminal cancer patients, vomit and pain resulting from inoperable intestinal obstruction, with the exception of obstruction of the upper abdomen, can be controlled through administration of analgesic and antiemetic drugs, in the hospital and at home, without recourse to nasogastric tube placement or intravenous hydration.
