Child with a tail

An interesting case of a child with a tail is reported. The child had a tail like structure in the back since birth, increasing with age. It was 20 cm. long, the longest tail so far described in the English literature. There was no functional complain. The result was excellent after excision as the problem was only cosmetic.     

Duodenogastric reflux after choledochoduodenostomy

Duodenogastric reflux (DGR) has been implicated in several disease processes. The present study was carried out to document the incidence and evaluate the clinical significance of DGR after choledochoduodenostomy (CDD). A total of 13 patients who had undergone cholecystectomy with a standard side-to-side CDD for choledocholithiasis or chronic pancreatitis were studied by symptom evaluation, scintigraphy, endoscopy, and gastric mucosal histology at least 6 months after surgery. The scintigraphic findings were then compared with those of 10 patients who had undergone cholecystectomy alone. Only two patients (15%) had mild dyspeptic symptoms. The incidence of DGR after CDD was 69% compared to 20% in the cholecystectomy alone group (P < 0.05). In the majority of patients the DGR was only mild to moderate and the severity correlated well with the degree of endoscopic gastritis, but not with the clinical symptoms or histological findings. These results indicate that while CDD is associated with a high incidence of DGR, its occurrence does not produce significant clinical symptoms.     

In vitro antibacterial activity of the volatile oil of Nigella sativa seeds against multiple drug-resistant isolates of Shigella spp. and isolates of Vibrio cholerae and Escherichia coli

The antibacterial activity of the volatile oil of Nigella sativa seeds was studied against 37 isolates of Shigella dysenteriae 1, Shigella flexneri, Shigella sonnei and Shigella boydii and 10 strains of Vibrio cholerae and Escherichia coli. Most of the strains were clinically resistant to ampicillin, co-trimoxazole and tetracycline. All the strains tested showed promising sensitivity to the volatile oil. The minimum inhibitory concentration (MIC) of the volatile oil for Shigella, Vibrio and Escherichia strains tested was between 50–400 μg/mL.     

Fluconazole compared with ketoconazole for the treatment of Candida esophagitis in AIDS. A randomized trial.

OBJECTIVE: To determine the clinical and endoscopic response of candida esophagitis to antifungal therapy and to compare the two oral antifungal agents, fluconazole and ketoconazole. DESIGN: Multicenter, randomized, double-blind trial. SETTING: Fifteen U.S. centers including university, private practice, and county hospital settings. PATIENTS: A total of 169 patients with the acquired immunodeficiency syndrome (AIDS); odynophagia, dysphagia, or retrosternal pain; white esophageal plaques at endoscopy; and pseudohyphae on esophageal brushings or biopsies. INTERVENTION: Patients were randomly assigned to fluconazole (100 mg/d) or ketoconazole (200 mg/d). Doses were doubled at week 1 or 2 if no symptomatic improvement had occurred during the preceding week. Therapy was continued for 2 weeks after resolution of symptoms or for a maximum of 8 weeks. MEASUREMENTS: Patients were clinically evaluated weekly, and laboratory tests were done every 2 weeks. Endoscopy was repeated within 5 days after the end of therapy. RESULTS: A total of 143 patients were clinically evaluable (assessed within 7 days after therapy), and 129 patients were endoscopically evaluable (endoscopy repeated after therapy). Endoscopic cure occurred in 91% of patients treated with fluconazole and in 52% of those given ketoconazole for a difference of 39% (95% Cl, 24% to 52%; P less than 0.001). Esophageal symptoms resolved in 85% of fluconazole-treated patients and in 65% of ketoconazole-treated patients for a difference of 20% (Cl, 6% to 34%; P = 0.006). Intention-to-treat analyses also yielded statistically significant differences for the comparisons listed above. Side effects were minimal and comparable in the two groups; only one patient in each group had therapy discontinued for adverse effects that were possibly related to the study medications. CONCLUSIONS: Fluconazole is associated with significantly greater rates of endoscopic and clinical cure than ketoconazole in patients with AIDS and candida esophagitis. Both drugs appear to be safe and well tolerated.     

Geriatric heart failure, depression, and nursing home admission: an observational study using propensity score analysis.

OBJECTIVE: Heart failure (HF) and depression are both common in older adults, and the presence of depression is known to worsen HF outcomes. For community-dwelling older adults, admission to a nursing home (NH) is associated with loss of independent living and poor outcomes. The objective of this study was to examine the effect of depression on NH admission for older adults with HF. METHODS: Using the 2001-2003 National Hospital Discharge Survey datasets, the authors identified all community-dwelling older adults who were discharged alive with a primary discharge diagnosis of HF. The authors then identified those with a secondary diagnosis of depression. Using a multivariable logistic regression model, the authors then determined probability or propensity to have depression for each patient. The authors used propensity scores for depression to match all 680 depressed patients with 2,040 nondepressed patients. Finally, the authors estimated the association between depression and NH admission using bivariate and multivariable logistic regression analyses. RESULTS: Patients had a mean (+/- standard deviation) age of 79 (+/- 8) years, 72% were women, and 9% were blacks. Compared with 17% nondepressed patients, 25% depressed patients were discharged to a NH. Depression was associated with 50% increased risk of NH admission (unadjusted relative risk [RR]: 1.50; 95% confidence interval [CI]: 1.28-1.74). The association became somewhat stronger after multivariable adjustment for various demographic and care covariates (adjusted RR: 1.60; 95% CI: 1.35-1.68). CONCLUSION: In ambulatory older adults hospitalized with HF, a secondary diagnosis of depression was associated with a significant increased risk of NH admission.     

Pharmacology of KB‐R7943: A Na+–Ca2+ exchange inhibitor

The Na⁺–Ca²⁺ exchange (NCX) system plays a pivotal role in regulating intracellular Ca²⁺ concentration in cardiomyocytes, neuronal cells, kidney and a variety of other cells. It performs a particularly important function in regulating cardiac contractility and electrical activity. One of the leading NCX inhibitors is KB‐R9743 (KBR) that appears to exhibit selectivity for Ca²⁺‐influx‐mode NCX activity (reverse mode of NCX). In this article we reviewed pharmacology of KBR and provide a brief summary of studies with other NCX inhibitors, such as SEA0400 (SEA) and SN‐6 (SN). Potential clinical usefulness of KBR and other NCX inhibitors is still controversial but the reviewed findings may be helpful in designing more selective and clinically useful NCX inhibitors for the treatment of cardiac, neuronal and kidney diseases.     

Rural Demographics Racial/Ethnic Diversification in Metropolitan and Nonmetropolitan Population Change in the United States: Implications for Health Care Provision in Rural America

The diversification of the rural population of the United States provides substantial challenges to the current and to future health care systems in rural areas. Because of a variety of historical, discriminatory, and other factors, minority populations have had lower levels of access to health care in rural as well as urban areas and higher rates of both mortality and morbidity than nonminority populations. Although minority health issues have often been seen as primarily urban issues, this article demonstrates that minority population growth has become a major component of total population growth in rural areas in the past several decades (accounting for nearly 62% of the net growth in the nonmetropolitan population of the United States in the 1980s and for nearly 42% in the 1990s), that future US population growth is likely to be largely a product of minority population growth (nearly 89% of US net population growth from 2000 to 2100 is projected to be due to minority population growth), and that the incidence of diseases and disorders in the US population will come to increasingly involve minority populations (by 2050 roughly 43% of all disease/disorder incidences would involve minority population members). The growth of younger minority populations with disproportionately impoverished socioeconomic characteristics will pose challenges for rural areas and health care systems, which also are likely to face health issues created by disproportionately older populations.     

Alteration of pulse configuration affects the pain response during diode laser photocoagulation

Background and Objective: The shape of the treatment pulse of the diode laser (810 nm) can be easily altered electronically in contrast to ion laser photocoagulators. We investigated whether changes in laser pulse shape influenced the subjective pain response in patients undergoing retinal photocoagulation when only topical anesthesia was used. Study Design/Materials and Methods: Twenty consecutive patients required peripheral retinal photocoagulation for proliferative diabetic retinopathy or extensive retinal breaks. Three diode pulse waveforms including a square wave, shaped-wave, and an envelope of micropulses were compared to one another. Power was adjusted so that each waveform delivered the same total energy. The patients subjectively ranked the intensity of any pain they experienced for each group of lesions. Responses were compared to one another using an analysis of variance. Results: 40% of patients found the standard square wave pulse to be significantly more painful (P < 0.05) than the shaped pulse mode and 30% found the square wave significantly more painful (P < 0.05) than the micropulse mode. Conclusion: Modification of the laser pulse waveform may ameliorate pain induced by diode laser photocoagulation of the retinal periphery. © 1995 Wiley-Liss, Inc.
