Acquired immunodeficiency without evidence of infection with human immunodeficiency virus types 1 and 2.

There have been three published cases of acquired immunodeficiency in which no evidence for infection with human immunodeficiency virus (HIV) types 1 and 2 was found. We have identified five other individuals, from the New York City area (four who have known risk factors for HIV infection), with profound CD4 depletion and clinical syndromes consistent with definitions of the acquired immunodeficiency syndrome (AIDS) or AIDS-related complex. None had evidence of HIV-1, 2 infection, as judged by multiple serologies over several years, standard viral co-cultures for HIV p24 Gag antigen, and proviral DNA amplification by polymerase chain reaction.

Primary treatment of pelvic osteosarcoma. Report of five cases.

Five patients, ages 12 to 20 years, with nonresectable primary (Patients 2, 3, and 5) and metastatic (Patients 1 and 4) pelvic osteosarcomas were treated with intraarterial cisplatin and concurrent radiation therapy from 1983 to 1987. Long-term local tumor control was achieved in all five patients. Patients 1 and 3 are alive with no evidence of local recurrence or metastatic disease at 77 and 56 months of follow-up, respectively, since diagnosis of the pelvic tumor. Patients 2, 4, and 5 died of metastatic lung disease at 25, 39, and 12 months, respectively, after diagnosis of the pelvic tumor. Patient 4 had no clinical or radiologic evidence of local recurrence. Control of tumor growth in patients with pelvic osteosarcomas can be achieved with regional chemotherapy and concurrent radiation therapy. These patients also should receive adjuvant intensive systemic chemotherapy to increase the probability of eliminating potential subclinical metastatic disease.

Giant colonic mucocele following palliative surgery for recurrent squamous cell carcinoma of the cervix.

We report an unusual complication following palliative surgery in a patient with carcinomatosis peritonei from recurrent squamous cell carcinoma of the cervix. At surgery the ascending colon was bypassed and isolated. Eight months later the patient presented with a giant mucocele. We believe this to be the first reported case in the gynecologic literature. This complication could have been prevented by adhering to the standard surgical management of fashioning a mucous fistula.

Fluoxetine ingestion: a one year retrospective study.

Fluoxetine (PROZAC) is a recently marketed straight chain antidepressant unrelated to the cyclic anti-depressants. There is only limited information on fluoxetine and a single case report on overdose (benign outcome) in the literature. In response to this we performed a 1y retrospective chart review at 2 AAPCC certified poison centers. Forty-four exposures to fluoxetine were reviewed from 1988; 31 cases were treated in a HCF, 2 cases were followed at home by phone and 11 cases were lost to follow up. Thirteen cases with follow up (FU) reported no coingestants; 3 cases reported increased anxiety without cardiovascular (CV) changes, 2 cases presented confused with out CV changes, and 8 cases were asymptomatic. Eight cases with FU had ETOH and/or benzodiazepines as a coingestant and experienced only a decreased level of consciousness that could be explained by the coingestant. Five cases remained asymptomatic with reported coingestants of APAP #3, lorazepam, haloperidol, molindone, alprazolam, propranolol, phenobarbital (level 18.2). Four cases were excluded from the evaluation due to the coingestants involved. No seizures were recorded in this series. Three possible drug reactions occurred; 2 cases had reactions with tranylcypromine (PARNATE), and 1 case with a diagnosis of septicemia had a severe hyperthermic reaction with therapeutic coingestants of mephytoin, verapamil, digoxin and indocin. We believe overdose with fluoxetine present minimal risk of serious cardiovascular or neurological complications.

Complement activity and selected hematologic variables in newborn foals fed bovine colostrum.

Serum complement activity and selected hematologic variables were evaluated in 5 newborn foals fed bovine colostrum (principal group) and 6 foals allowed to nurse their dam (control group). Also, bovine colostrum was evaluated for anti-equine antibodies. Precolostral serum hemolytic and conglutinating complement activities were low and increased similarly in foals of both groups to reach adult values between 1 and 3 weeks after birth. Bovine colostrum strongly agglutinated, but did not hemolyse principal foals' RBC and blood containing all known equine blood group alloantigens. Hemolysis was not detected after administration of bovine colostrum. Physiologic anemia developed in foals of principal and control groups during the first week of life. Erythrocyte osmotic fragility in foals of the principal group prior to and after the ingestion of colostrum remained unchanged. However, at 36 hours after birth, there was a significant decrease in erythrocyte osmotic fragility in foals fed homologous colostrum.

Hemodynamic evaluation of isosorbide dinitrate in alcoholic cirrhosis. Pharmacokinetic-hemodynamic interactions.

Isosorbide dinitrate, a long-acting organic nitrate, has been shown to decrease portal pressure in the experimental animal and humans. We conducted a double-blind randomized hemodynamic evaluation of the effects of placebo and 10 mg and 20 mg isosorbide dinitrate in stable individuals with alcoholic cirrhosis. Baseline values for all three groups were similar. Isosorbide dinitrate resulted in a peak reduction of the hepatic venous gradient of 24.7% +/- 3.0%, with significantly decreased values 4 h after the administration of the 20-mg dose. A reduction of arterial pressure and cardiac index (peak decrease of 25.7% +/- 1.5%) was well tolerated by 13 of 15 patients. Changes in mean arterial pressure were not predictive of modifications in the hepatic vein wedge pressure. There was no relation between the area under the plasma isosorbide dinitrate concentration curve and hemodynamic changes. Levels of isosorbide-5-mononitrate, a vasoactive metabolite, were detectable for an 8-h period. Isosorbide dinitrate significantly reduced portal pressure in stable cirrhotics, in association with systemic hemodynamic changes. Thus, titration of isosorbide dinitrate is required to maximize hemodynamic benefits in individual patients. As the decrease in portal pressure is more predictable than the effect of previously tested pharmacologic agents, isosorbide dinitrate should be evaluated for its efficacy in the management of portal hypertension.

Acute dissection originating in the abdominal aorta.

A primary abdominal aortic dissection was encountered in a 53-year-old hypertensive man who was admitted with a 2-week history of back pain. Treatment with an infrarenal aortic bifurcation graft complemented by reconstruction of the proximal aortic cuff was curative.

Hepatic artery pseudoaneurysm: diagnosis with real-time and pulsed Doppler US.

Duplex ultrasonography (US), consisting of real-time and pulsed Doppler US, was used to identify a pseudoaneurysm in a patient with recurrent bleeding and chronic pancreatitis. The authors present a case that illustrates the limitations of real-time US in evaluating sonolucent masses in pancreatitis and the need for using pulsed Doppler technique.

Early effects of traumatic brain injury on young children's language performance: a preliminary linguistic analysis.

Language skills undergo rapid development during the early childhood years, so that by the time children start school they are competent communicators with well established syntactic, semantic and pragmatic abilities for their age. Little is known about the effects of traumatic brain injury (TBI) on the acquisition of these language skills during the early childhood years. This study used a prospective, cross-sectional design to compare the language abilities of young children following their head injury. Fifteen brain injured children, aged between 4-6 years, were divided into three injury groups depending on severity of injury, i.e. mild, moderate and severe, and compared with a matched community control group. They were assessed within 3 months of sustaining their injury on a range of expressive and receptive language tests, and free speech conversation samples, which were analysed pragmatically and syntactically. Results indicated that the severe group performed most poorly on language tasks. It is suggested that linguistic evaluation is an important component of follow up at least for the severe head injured population.
