RESUMO

African-born immigrant women, and particularly refugees and asylum seekers, are at risk for reproductive health disparities but inadequately use relevant gynecologic services. We sought to elucidate perspectives on gynecologic care in a population of Congolese and Somali immigrants. We conducted a secondary qualitative analysis of focus group data using a grounded theory approach and the Integrated Behavioral Model as our theoretical framework. Thirty one women participated in six focus groups. Participant beliefs included the states of pregnancy and/or pain as triggers for care, preferences included having female providers and those with familiarity with female genital cutting. Barriers included stigma, lack of partner support, and lack of resources to access care. Experiential attitudes, normative beliefs, and environmental constraints significantly mediated care preferences for/barriers to gynecologic health service utilization in this population. Centering of patient perspectives to adapt delivery of gynecologic care to immigrants and refugees may improve utilization and reduce disparities.

RESUMO

Zidovudine is the only drug currently approved for the treatment of HIV infection. The present recommended doses found to be efficacious in patients with AIDS (200 mg every 4 h) achieve serum zidovudine concentrations greater than 0.267 micrograms/ml (1 mumol/l). Since patients often take zidovudine with food, we have investigated the effect of a liquid high-fat meal on the rate of absorption of zidovudine and on the peak serum concentration achieved. Eight patients received their usual dose of zidovudine (100 mg or 250 mg), with and without a liquid high-fat meal, on two separate study days, in a randomized crossover fashion. Blood and urine samples were collected over a 4-h period. In the absence of food, zidovudine is rapidly absorbed; the time to reach maximal serum concentration (Tmax) was 0.68 (+/- 0.25) h and the mean peak serum concentration (Cmax) achieved was 0.49 (+/- 0.3) micrograms/ml (dose normalized to 100 mg dose). In the presence of a high-fat meal, Tmax was significantly prolonged [1.95 (+/- 0.69) h; P less than 0.05] and the Cmax reduced [0.245 (+/- 0.12) micrograms/ml; P less than 0.05]. This demonstrates that to achieve maximal zidovudine serum concentrations, patients should take this medication on an empty stomach.

RESUMO

A study was performed with 10 hospitalized patients to determine the percentage of an aminoglycoside dose (tobramycin or gentamicin) that is absorbed systemically after being instilled into the endotracheal tube at steady state. All patients were on respirators, had indwelling urinary catheters, and had creatinine clearances estimated to be greater than or equal to 40 ml/min. Tobramycin or gentamicin (40 mg) was instilled every 4 h directly into the endotracheal tube. Nine patients also received systemically a different aminoglycoside from that administered through the endotracheal tube. Urine was collected over a 4-h dosing interval at steady state (after at least 5 doses of the drug). The amount of aminoglycoside excreted over the 4-h interval was measured and expressed as percentage of the dose administered over that period. The range of percentage of dose absorbed was 1.5 to 34%, with a mean of 16.7 +/- 11.4% standard deviation and a median of 16.5%. The coefficient of variation was 68%. Levels of the endotracheally administered aminoglycoside in serum were measured, and all were less than 1.0 microgram/ml. While a large degree of variability in absorption was observed in this study, significant amounts of aminoglycosides could be absorbed in some patients. However, levels apparently did not accumulate in sera of patients with adequate renal function, and an empirical dosage reduction in intravenous aminoglycoside should not be necessary with the addition of endotracheally instilled aminoglycoside in patients with creatinine clearances greater than 40 ml/min.

RESUMO

It has been suggested that inhalational anesthetics should be discontinued at least 15 minutes prior to termination of extracorporeal circulation (ECC) to avoid myocardial depression. However, data regarding elimination of inhalation agents via a bubble oxygenator from hypothermic, hemodiluted patients have not been previously reported. The washout of isoflurane (ISF) from ten cardiac surgical patients using mass spectrometry was studied. The mean baseline oxygenator exhaust concentration of ISF was 0.85% prior to termination of ECC. Oxygenator concentration of ISF decreased to less than 0.05% in 8.8 +/- 2.5 minutes. Eight of ten patients had ISF washout curves best characterized by a one-compartment model, with a mean time constant of 1.94 minutes. Therefore, 95% washout of ISF should occur in 5.8 minutes (three time constants). It is suggested that ISF may be used closer to the termination of ECC than previously recommended without fear of significant myocardial depression.

RESUMO

A patient with Stevens-Johnson syndrome is described, and the literature concerning the etiology, pathophysiology, clinical manifestations, and management of Stevens-Johnson syndrome is reviewed. A 2 1/2-year-old girl was treated with phenobarbital and i.v. ampicillin, followed by oral amoxicillin, for an upper-airway infection, otitis media, and febrile seizures. The fever returned, and she was treated unsuccessfully with penicillin and cefaclor. She was admitted to the hospital and treated with i.v. ampicillin. Within 24 hours an erythematous maculopapular rash developed. Phenobarbital was discontinued and phenytoin was begun. Four days later bullous lesions developed; ampicillin and phenytoin were discontinued, and cefazolin and phenobarbital were given. By the eighth day severe sloughing of the skin occurred over 75% of her body, and mucosal sloughing was apparent. The patient's condition was diagnosed as Stevens-Johnson syndrome. Porcine xenografts were immediately grafted to 75% of her total body surface. Severe lesions of the mouth and pharynx made parenteral nutrient therapy necessary, and ocular complications required the care of an ophthalmologist. Although the skin had healed by 14 days after grafting, another 14 days of treatment for respiratory complications was required. Stevens-Johnson syndrome is a severe exfoliative dermatitis accompanied by fever, inflammation of the gastrointestinal mucosa, and severe purulent conjunctivitis. It is associated with high morbidity and mortality. The etiologic factors may be iatrogenic (e.g., various antibiotics and anticonvulsants), infectious, or idiopathic. Respiratory complications, leukopenia, infections, erosion of the gastrointestinal mucosa, fluid and electrolyte disturbances, and chronic ocular complications may occur.(ABSTRACT TRUNCATED AT 250 WORDS)
