Hais cuaj txub kaum txub--to speak of all things: a Hmong cross-cultural case study

Cross-cultural medicine is a field that describes how disparate value and belief systems concerning health and disease affect the delivery of health care. This report describes the conflict between a Hmong immigrant family and the Western medical establishment over the care of their child with end stage renal disease [ESRD]. The health care providers, social service agencies and medical center failed to adequately respond to the needs of the family. The medical staff [nephrologist, nurse coordinator, dietician, social worker, and CPS worker] worked with a transcultural nurse, Hmong community health worker and the family, to design and negotiate a treatment plan that would be acceptable to the family and the health care team. Trust was reestablished between the family and the healthcare providers and the medical outcome for the child improved.

Using a transcultural, patient based approach to improve patient outcome in a pediatric ESRD patient

In this case, the medical team learned about the Hmong cultural beliefs and collaborated with the family to design a plan of care that included their nonwestern medical practices. Improved health care for the child resulted from a partnership between the Hmong community, extended family members, cross-cultural nursing staff, and the nephrology team. This experience amended existing protocols for managing diverse populations and because of its success, the pediatric nephrology team was awarded the UCSD Healthcare Diversity Award in 1998.

Transjugular intrahepatic portosystemic shunt prior to renal transplantation in a child with autosomal-recessive polycystic kidney disease and portal hypertension: A case report

Autosomal-recessive polycystic kidney disease (ARPKD) can cause renal failure and portal hypertension in children. Portal hypertension may complicate the course of renal transplantation (Tx). We report the successful outcome of a patient with end-stage renal disease (ESRD) and portal hypertension treated with transjugular intrahepatic portosystemic shunt (TIPS), a minimally invasive endovascular technique of portosystemic shunt, prior to renal Tx.

Neoral pharmacokinetics in Latino and Caucasian pediatric renal transplant recipients

Interpopulation variability of drug pharmacokinetics (PK) has been described. For example, the systemic clearance of nifedipine is higher in Mexicans than Caucasians. African-Americans have a lower cyclosporine bioavailability than Caucasians. Limited data are available in the Latino population. Under identical conditions, we compared the PK profile of Neoral (cyclosporine for microemulsion) obtained in stable pediatric renal transplant recipients of Latino and Caucasian origin. A slightly lower area under the curve (AUC) when corrected for dose per body surface area or per kilogram of body weight was observed in Caucasians compared with Latinos. This difference was more pronounced in the younger age group (< 12 years) with a higher peak-to-trough ratio. However, the Caucasians required a higher dosage of Neoral than the Latinos to achieve that same AUC. There was no difference between the groups in the time (tmax) to reach maximal concentration (Cmax) of Neoral. A higher apparent clearance of the drug was observed in the Caucasians compared with the Latinos, especially in the younger age group. No differences in pre- and post-dose levels were observed between the two groups. These differences might affect dose adjustment between the two subpopulations.

Rapid heroin detoxification using a single high dose of buprenorphine

To test the effect of 32 mg of buprenorphine on the withdrawal process from heroin, 10 street-heroin using subjects were given 32 mg of sublingual buprenorphine, following heroin abstinence of 24 hours. Withdrawal symptoms were monitored during the first few hours, and followed for six days after buprenorphine administration, after which naltrexone (50 mg) was introduced to prevent future heroin use. Nine subjects completed detoxification with negligible withdrawal symptoms and a smooth transition to naltrexone. One subject was excluded from the study due to methadone ingestion prior to experiment. These results strongly suggest that painless detoxification from heroin can be obtained by a single high dose of buprenorphine.

Innovative mentoring programs to promote gender equity in academic medicine

The authors describe the history, characteristics, and goals of four innovative programs, each in a medical school, that were established in 1998 to help faculty members of both sexes obtain mentors and thereby facilitate their career advancement. The programs were established as the result of an initiative by the Office on Women's Health (OWH) within the U.S. Department of Health and Human Services. Specifically, the OWH convened the National Task Force on Mentoring for Health Professionals, which determined that two principles are paramount to the success of any mentoring relationship or program: institutional commitment and institutional rewards and recognition to mentors. In accordance with the task force findings, the OWH created the National Centers of Leadership in Academic Medicine, one at each of four medical schools: MCP Hahnemann School of Medicine; the University of California, San Diego, School of Medicine; East Carolina University School of Medicine; and Meharry Medical College School of Medicine. The authors give highlights of each program's goals and progress, and note that, ideally, these programs will eventually serve as models for similar programs at other schools. Programs such as these foster the advancement of a diverse faculty, a more supportive academic environment, and the education of providers who are sensitive to the needs of all their patients, staff, and colleagues.

Nonsteroidal anti-inflammatory drug use in adolescence

Nonsteroidal anti-inflammatory drugs (NSAIDs) have been recently released as over-the-counter drugs making them more widely available to the general public. We present five cases of adolescents with complications, including acute and chronic renal failure, related to the use of NSAIDs. Risk factors for NSAID nephrotoxicity include chronic illness, dehydration, ethanol and use of other medications. Adolescents should be educated about the risks and prevention of NSAID toxicity.

The syndrome of autoimmune interstitial nephritis and membranous nephropathy

A 2-year-old male patient was evaluated for Fanconi syndrome with hypertension and failure to thrive. Renal biopsy revealed autoimmune interstitial nephritis with membranous nephropathy. The patient developed autoimmune hemolytic anemia and intractable diarrhea with villous atrophy of the jejunum. He progressed to end-stage renal disease and was transplanted without recurrent disease. Immune work-up done prior to immunosuppressive therapy showed marked elevation of IgE. Studies of T lymphocyte cytokine production showed normal production of interleukin-4 but depressed levels of interferon-gamma. The simultaneous occurrence of autoimmune interstitial nephritis and membranous nephropathy in a young male represents a unique syndrome. Abnormalities of T lymphocyte subpopulations and their cytokines may be involved in the pathogenesis of this disorder.

Pharmacologic amino acid acylation in the acute hyperammonemia of propionic acidemia

An infant with propionic acidemia presented at one month of age with hyperammonemic coma. Treatment by two double-volume exchange transfusions did not have an appreciable effect, but hemodialysis led to a substantial reduction of the serum concentration of ammonia on two occasions. Nevertheless, continued therapy with sodium benzoate, arginine-HCl, carnitine and lactulose did not have any observable effect on the blood concentration of ammonia. Treatment with sodium phenylacetate was followed by a reduction in serum concentrations of ammonia to normal levels which were maintained. These observations demonstrate the dramatic reduction in serum concentrations of ammonia that may be obtained in patients with organic acidemia by hemodialysis. They suggest that pharmacologic acylation therapy with phenylacetate may be of lasting benefit in the management of this complication.

Accumulation of aluminum in a nondialyzed uremic child receiving aluminum hydroxide

A child with renal insufficiency was treated with the oral phosphate binder aluminum hydroxide from age 6 to 31 months. The prescribed dose of elemental aluminum varied from 31 to 108 mg/kg/d. Concurrently the patient developed vitamin D-resistant osteomalacia which failed to improve with parathyroidectomy. Encephalopathy with myoclonic seizures, loss of speech, and motor impairment also occurred. Serum and bone aluminum levels were elevated at 334 micrograms/L (normal 7 +/- 3 micrograms/L) and 156 mg/kg (normal 3.3 +/- 2.9 mg/kg), respectively. This case demonstrates that aluminum may accumulate in tissue of children receiving oral aluminum hydroxide. The accumulation of aluminum may have contributed to the vitamin D-resistant osteomalacia and the encephalopathy in this patient. Children receiving aluminum-containing antacids as phosphate binders should be monitored for aluminum accumulation and signs of aluminum intoxication.

Oral converting enzyme inhibitor in malignant hypertension

Malignant hypertension, which developed in a 9-year-old boy after an episode of haemolytic uraemic syndrome, could not be controlled with antihypertensive agents. However, treatment with oral converting enzyme inhibitor (captopril) was effective in controlling the blood pressure and it averted bilateral nephrectomy. No adverse effects from the drug were noted.
