OBJECTIVE: This study sought to examine differences in the nutritional composition of binges, both qualitatively and quantitatively, between participants with binge eating disorder (BED) and bulimia nervosa (BN) taken from a sample of treatment-seeking Black and White women. Overall qualitative and quantitative differences between diagnostic categories, regardless of ethnicity, were also explored. METHOD: Patients seeking treatment for eating disorders were assessed on binge content. Black (n=26) and White (n=26) participants were matched on age and body mass index (BMI). RESULTS: The binges of individuals with BN were lower in percent protein, but higher in calories, carbohydrates, and sugar, than those individuals with BED. However, there was little difference as a function of ethnicity between treatment-seeking Black and White women. DISCUSSION: Preliminary data suggest that health professionals are faced with similar binge eating pathology, regardless of ethnicity, despite, probably, etiologic variation. The importance of the role of ethnicity in the expression of eating disorders is discussed. 相似文献

The use of fasciocutaneous flaps for the reconstruction of lower leg soft-tissue defects inflicted during the bombing of our country is presented in this case report. The experience with 9 patients with soft-tissue defects of the lower leg is presented with the aim of examining the possibilities of war-wound reconstruction. The results of the earlier use of fasciocutaneous flaps in the lower leg reconstruction as well as the those obtained during the reconstruction of the lower leg soft-tissue defects in war wounds was proven to be safe and reliable method of the reconstructions of severe lower leg injuries, particularly of its distal segment and the malleolus region. 相似文献

The Adolescent Treatment Models initiative, a 10-site, multimodality, prospective study, was designed to evaluate adolescent substance abuse treatment outcomes and to assess the relative efficacy of different treatment models. Based upon longitudinal data gathered at multiple assessment points using a standardized instrument, treatment outcome trajectories were determined for a cohort of 1,057 adolescents from entry into substance abuse treatment until 12 months post-intake. Client outcomes on substance use and program effectiveness were explored across individual treatment programs and levels of care. Strong treatment effects, defined as a significant reduction in alcohol and other drug use at three months post-intake, were found. The reductions of greatest magnitude in relation to pretreatment use occurred among adolescents in residential treatment. Within level of care, few significant differences in treatment effects were found between programs. Relapse effects, defined as an increase in substance use at 12 months relative to three months, were observed across nearly all programs, but varied in relation to treatment modality. This is most evident among those entering residential treatment, with the highest rate of relapse occurring among adolescents in long-term residential treatment care. Despite strong evidence of treatment effectiveness, continuing care is vital to maintenance of treatment benefit. 相似文献

BACKGROUND: Gastrointestinal stromal tumors (GISTs) are rare mesenchymal tumors of the gastrointestinal tract localized mostly in the upper or medial part of the digestion tract. CASE: A colonic GIST in a young woman extended to the pelvis, giving the impression of an ovarian tumor. CONCLUSION: In the case of a pelvic mass, especially if other unusual anamnestic data and signs are present, the possibility of other than a gynecologic tumor has to be considered. Every effort should be made to identify the origin of the tumor and related anatomic structures, especially the ovaries. 相似文献

Molecular events in the progression of recurrent respiratory papillomatosis to carcinoma 总被引:3,自引:0,他引:3

CONTEXT: Identification of the type of human papillomavirus (HPV) by polymerase chain reaction and sequencing to determine coinfection or superinfection (by more than 1 HPV type) and other molecular events have not been reported in a series of patients exhibiting the morphologic spectrum of recurrent respiratory papillomatosis progressing to carcinoma. DESIGN: Four cases of juvenile-onset recurrent respiratory papillomatosis progressing to carcinoma (no history of smoking or irradiation in 2 cases) were studied. Morphologically distinct foci (squamous papilloma, pulmonary papillomatosis, squamous dysplasia subjacent to carcinoma, and squamous carcinoma) were subjected to laser capture microdissection and polymerase chain reaction amplification using general primers in addition to type-specific primers for HPV types 16 and 18. Direct sequencing of polymerase chain reaction products identified the type of HPV. The tissue sections were immunostained using antibodies to p53, pRb, p21(WAF1), and p16 proteins with a semiquantitative assessment. RESULTS: Human papillomavirus 11 was the only type of HPV identified in all lesions of all cases associated with recurrent respiratory papillomatosis. There was a marked increase in p53 protein expression in foci of dysplasia and carcinoma as compared to squamous papilloma and pulmonary papillomatosis. An inverse correlation between p53 and p21(WAF1) protein expression was noted in all lesions. pRb protein expression increased from the benign to the malignant end of the spectrum. p16 protein was expressed in all lesions. CONCLUSIONS: Infection by HPV-11 may be an early event associated with progression of recurrent respiratory papillomatosis to carcinoma. Increased expression of p53 and pRb proteins and a reduced expression of p21(WAF1) protein appear to be significant subsequent events. 相似文献

Purpose:
Bladder autoaugmentation is a procedure that includes detrusoromyotomy or detrusorectomy with an aim to release intact urothelium, which then prolapses and increases bladder capacity and compliance. Covering of the prolapsed urothelium usually is done by using deepithelialized pedicled colonic or gastric patch. The authors present their first experiences with detrusorectomy using rectus muscle for hitch and backing.Methods:
Between August 1999 and February 2002, autoaugmentation was performed in 19 patients (12 girls and 7 boys) aged 4 to 12 years (median, 8). All patients had a neurogenic bladder with small capacity and poor compliance. Detrusorectomy usually involves the whole upper half of the bladder to achieve regular shape of the huge prolapsed urothelium. Both rectus muscles are dissected from their anterior and posterior sheaths. Urothelium is sutured to the muscle at several points to prevent its retraction and shrinkage. This way, bladder is fixed and hanged on rectus muscles.Results:
Follow-up was 6 to 35 months (median, 21). The new bladder capacity was increased in all patients and ranged from 190 to 411 ml (median, 313). All patients had clinical improvement and better compliance.Conclusions:
Detrusorectomy with rectus muscle hitch and backing is a safe and simple procedure. However, long-term results are needed to define value of this procedure. 相似文献109.
The dependence of free flaps on the original vascular anastomosis was investigated using color duplex . Although functional and morphological changes in flaps have been previously documented, showing the formation of new vessels across the flap inset, this was not observed in this study. Even after 1 year after surgery the free flaps were still dependent on the original anastomoses for their blood supply, with no other significant vessels obvious on duplex to supply the flap. This evidence as well other published reports suggest that at least the lower extremity and the chest wall do not develop collateral circulation to a free tissue transfer. Late postoperative division of the vascular pedicle either in the lower limb or the chest wall should be approached with the knowledge that neovascularization across the flap margins is the exception rather than the rule. 相似文献

The effects of different concentrations of N(G)-nitro-L-arginine methyl ester (L-NAME) (0.3, 1, 3, and 10 mM), a non-selective inhibitor of NOS, on the effect of aminophylline on the isometric contraction of the isolated rat hemidiaphragm were investigated. The muscle contractions were induced by direct subtetanic electrical stimulation. Aminophylline (0.36 - 3.60 mM) produced a typical concentration-dependent increase in both parameters of the isometric contraction: tension developed (Td) and the maximum rate of rise of tension (dT/dt max). The second series of additions of aminophylline produced a more pronounced effect. L-NAME (0.3, 1, 3, and 10 mM, 30 min of incubation without stimulation) itself did not change Td and dT/dt max. However, L-NAME (1, 3, and 10 mM) produced a statistically significant potentiation of the effect of aminophylline on Td and dT/dt max. 相似文献
