Background: The complications of the gastric pouch in gastric bypass surgery are well known. Since the first report of this surgery 30 years ago, new technical aspects that make it safer and more effective have been implemented. Methods: As a modification of gastric bypass, the authors have performed 305 vertical banded gastroplasty-gastric bypass procedures. Two groups of patients underwent the procedure: Group I (n = 206) without a limb of jejunum interposed between the gastric pouch and the excluded stomach, and Group II (n = 99) with a limb of jejunum interposed between the pouch and the stomach. The results regarding excess weight loss and complications of the gastric pouch during the first year after surgery were compared. Results: Age, sex, initial weight, body mass index, and percentage of ideal weight were similar in both groups. Excess weight loss was also similar. The complications in Group I were 1 leak, 3 left subphrenic abscesses, 2 erosive gastritis with bleeding, 1 stenosis of the gastrojejunostomy, 1 perforated ulcer, and 4 marginal ulcers with bleeding. Two patients in Group II developed bleeding from the staple-line. Conclusions: These preliminary data suggest that complications of the gastric pouch can be reduced by interposing a limb of jejunum between the pouch and the excluded stomach. This is an early experience; long-term results are pending.  相似文献

Medial temporal lobe atrophy on MRI in dementia with Lewy bodies   总被引:7,自引:0,他引:7  
OBJECTIVE: To investigate whether medial temporal lobe atrophy (MTA) on MRI is less frequent in dementia with Lewy bodies (DLB) compared with AD and vascular dementia (VaD), and to determine the diagnostic utility of MTA in the differential diagnosis of dementia. METHOD: Coronal T1-weighted 1.0-T MR images were acquired in patients with DLB (consensus criteria; n = 26; mean age, 75.9 years), AD (National Institute of Neurological and Communicative Disorders and Stroke-Alzheimer's Disease and Related Disorders Association; n = 28; mean age, 77.4 years), VaD (National Institute of Neurological Disorders and Stroke-Association Internationale pour la Recherche et l'Enseignement en Neurosciences; n = 24; mean age, 76.9 years), and normal control subjects (n = 26; mean age, 76.2 years). Cognitive function was assessed using the Cambridge Cognitive Examination (CAMCOG), and MTA was rated visually using a standardized scale. RESULTS: MTA was more frequent and severe in all dementia groups compared with control subjects (AD, 100%; VaD, 88%; DLB, 62%; control subjects, 4%; p < 0.001). Comparing dementia groups, MTA scores were significantly lower in DLB than AD (p = 0.002), with a trend toward less atrophy in DLB compared with VaD (p = 0.07). The absence of MTA had a specificity of 100% and 88% for separating DLB from AD and VaD respectively, and a sensitivity of 38%. In patients with DLB, MTA increased with age (r = 0.58, p = 0.002), and in all dementia patients MTA correlated with memory impairment (combined memory score, r = -0.34, p = 0.003) but not total CAMCOG score or other subscales. CONCLUSION: Patients with DLB have significantly greater MTA than control subjects but significantly less than those with AD. The authors confirmed that the presence of MTA is useful in detecting AD but less useful in differentiating between dementias. However, in the differentiation of DLB from AD and VaD, the absence of MTA is highly suggestive of a diagnosis of DLB.  相似文献

Summary We measured serum 1-antichymotrypsin (ACT) levels in patients with Alzheimer's disease (AD), Parkinson's disease (PD), Multiple System Atrophy (MSA) and age-matched controls to evaluate whether serum ACT levels in AD patients were elevated and whether ACT levels in PD patients with dementia differed from those in PD or AD. None of the patient groups displayed an increase in ACT levels. We conclude that serum ACT is not useful as a marker, nor in AD nor in dementia in PD.  相似文献

A renal tumor developing in a patient receiving cyclophosphamide (Cytoxan) therapy for Wegener granulomatosis is reported. The tumor was similar histologically to the "immunoblastic" sarcoma that develops in renal allograft recipients as a complication of immunosuppressive therapy. This case report strengthens the cause and effect relationship between immunosuppressive drug usage and the subsequent development of neoplasia.  相似文献

Objectives: To describe the physical growth patterns of infants born to narcotic dependent mothers (INDM) over a 12 months period and, if possible, to relate the growth to drug taking patterns during pregnancy.
Methodology: The growth of a cohort of 43 INDM was measured during the first 12 months of life. Weight and length measurements were compared with percentile charts and converted to Z scores. Questionnaire data about drug taking practices, demographic variables and the neonatal period (including withdrawal scores) were obtained.
Results: Twenty-four (55.8%) of INDM had evidence of neonatal drug withdrawal requiring treatment with phenobarbitone. At birth, Z scores for weight and length indicated relative intrauterine growth retardation. By 12 months, there had been some catch up growth, but Z scores for weight and length were still below zero. Persistent weight retardation at 12 months was correlated with methadone dosage during pregnancy, but not the need for phenobarbitone therapy.
Conclusions: The growth patterns of INDM in the first 12 months of life indicated that at birth there was evidence of intrauterine growth retardation, but by 12 months the growth was little different from the rest of the community. There appears to be some influence of narcotic agents taken while pregnant on subsequent growth of INDM.  相似文献

Antifungal activity of natural products is being studied widely. Saponins are known to be antifungal and antibacterial. We have isolated eight steroid saponins from Tribulus terrestris L. , namely TTS-8, TTS-9, TTS-10, TTS-11, TTS-12, TTS-13, TTS-14 and TTS-15. TTS-12 and TTS-15 were identified as tigogenin-3-O-β-D-xylopyranosyl(1→ 2)-[-β-D-xylopyranosyl( 1 → 3 ) 3-β- D-glucopyranosyl ( 1 → 4 )- 1- α-L-rhamnopyranosyl ( 1 → 2 ) 3-β-D-galactopyranoside and tigogenin-3-O-β-D-glucopyranpyranosyl(1→2)-[-β-D-xylopyranosyl(1→ 3)3-β-D-glucopyranosyl(1→4)-β-D-galactopyranoside, respectively. The in vitro antifungal activities of the eight saponins against six fluconazole-resistant yeasts, Candida albicans, Candida glabrata, Candida para psilosis , Candida tropicalis , Candida krusei , and Cryptococcus neo f ormans were studied using microbroth dilution assay. The results showed that TTS-12 and TTS-15 were very effective against several pathogenic candidal species and C. neoformans in vitro. It is noteworthy that TTS-12 and TTS-15 were very active against fluconazole-resistant C. albicans (MIC80 = 4.4, 9.4 mg/ml), C. neoformans (MIC80 =10.7, 18.7 mg/ml) and inherently resistant C. krusei (MIC80 =8.8, 18.4 mg/ml). So in vivo activity of TTS-12 in a vaginal infection model with fluconazole-resistant C. albicans was studied in particular. Our studies revealed TTS-12 also showed in vivo activities against fluconazole-resistant yeasts. In conclusion, steroid saponins TTS-12 and TTS-15 from Tribulus terrestris L. have significant in vitro antifungal activity against fluconazole-resistant fungi, especially TTS-12 also showed in vivo activity against fluconazole-resistant C. albicans.  相似文献

Biopsy specimens of clinically normal skin of 9 consecutive patients with SLE were examined ultrastructurally to determine the presence and frequency of microtubular inclusions. Ten blood vessels were examined in each specimen; every specimen contained at least two positive blood vessels, and some contained 80 to 100% positive vessels. No correlation was found between the frequency of the inclusions and either the disease duration or antinuclear factor titer. The inclusions tended to be more frequent in patients with more acute disease. The absence of inclusions in normal skin may mitigate a diagnosis of SLE.  相似文献
