Mucormycosis of the gastrointestinal tract is a rare infection that usually occurs in patients who are immunocompromised and carries a high mortality. We report four cases of gastrointestinal mucormycosis seen over a one year period with different presentations, risk factors and different anatomical sites of involvement. A preoperative diagnosis was made only in one patient. All underwent surgery, three survived and one died postoperatively from multiorgan failure. 相似文献

Introduction and objective
Gestational weight gain (GWG) has been reported to be associated with pregnancy outcomes. The aim of this study was to evaluate the effects of GWG on maternal and birth complications.Materials and methods
A prospective and longitudinal cohort study was conducted among pregnant women who had attended antenatal centers in Constantine, Algeria, between 2013 and 2015. Two hundred pregnant women aged 19 to 41 years old were followed for 9 months of pregnancy. They underwent body weight measurement during routine examination at first, second and third trimester. GWG was categorized as below, within or above the Institute of Medicine (IOM) (2009) recommendations. Data included age and parity. Pregnancy outcomes were analyzed in relation to GWG.Results
Mean GWG was 8.9 ± 5.4 kg. Among all subjects, only 27.5% of women had gained the recommended amount of weight, with 48.5% gaining less than recommended, and 24.0% gaining more than recommended by the IOM. High birth weight was significantly more frequent in women with excessive weight gain, compared to those with normal gain (27.1% vs 14.5%, P = 0.04). The percentage of low birth infants was statistically very high in pregnant women with excessive weight gain, compared to women with normal gain (14.6% vs 3.6%, P = 0.04). The risk of gestational hypertension increased with excessive GWG (P < 0.01).Conclusion
The pregnancy and birth outcomes depend on the women's gestational weight gain. 相似文献3.

The inhibitory action of five azoles namely benzotriazole (BTA), mercaptobenzothiazole (MBT), benzimidazole (BIMD), mercaptobenzimidazole (MBIMD) and thiadiazole (TDA) on copper was examined in sodium borate solution of pH 6.4, 8.4 and 10.4 using cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). A considerable drop off in the corrosion rate of copper was detected in the presence of the investigated compounds. CV showed that the inhibitors were of mixed type that they affect both the anodic and cathodic currents. Impedance spectra were characterized in terms of the charge transfer resistance and transport of copper ions through the oxide layer. The results indicate that the surface layer is of dielectric nature, and its protection increases with increasing inhibitor concentration and solution pH. On the basis of calculated adsorption data the process was concluded as chemisorption. Some quantum chemical parameters were also calculated using ab initio Hartree–Fock 6-31G*basis set and were used to complement the experimental results. The relative inhibition efficiencies of the azoles in controlling the copper corrosion was found to be in order of MBT > TDA > MBIMD≈BIMD > BTA. 相似文献

Hydatidosis of bone is rare. Vertebral localizations predominate. Standard imaging may be misleading, suggestive of a malignant tumor or infection. We present the case of a patient with a humeral hydatid. This localization is very rare and presents an unusual radiographic aspect. Computed tomography produces an image suggestive of a tumor. The correct diagnosis can be established with MRI, particularly with the STIR sequence. In our patient, MRI enabled us to establish the diagnosis preoperatively and evaluate extension. MRI has been found to be highly contributive to the diagnosis of hydatidosis of bone and for assessment of intra- and peri-osseous extension. 相似文献

Varicella zoster virus (VZV) infection has been implicated in multiple sclerosis (MS), but direct causal involvement has been disputed. Nevertheless, knowledge of VZV exposure is important, given the risk of serious complications of first exposure while undergoing immunosuppressive treatment, in particular with fingolimod. We distributed questionnaires to MS clinic patients, requesting information about history of chickenpox, sibling/household/occupational exposure, history of zoster (shingles), and disease-modifying treatment. A random, proportionally representative sample of 51 patients that included patients with positive, negative, and unknown chickenpox history were selected for determination of VZV IgG by ELISA. Of 1206 distributed questionnaires, 605 were returned (50% response rate). Of these, 86% reported history of chickenpox, 5.6% gave negative history, and 8.5% did not know. Of 594 who answered the zoster question, 78% gave a negative response, 4% did not know, and 104 (17%) answered yes. Of these, 83 reported 1 episode; 12 had 2; 5 had 3; and 1 each reported 5, 6, and 15 episodes. Of 51 patients tested for VZV IgG (44 “yes,” 4 “no,” and 3 “I don’t know” answers to the question of whether they had chickenpox), 48 were seropositive; the 3 seronegative all had reported having had chickenpox. The high rate of MS patients reporting prior chickenpox infection is comparable with previous reports. A substantial proportion of MS patients, estimated to be higher than an age-matched general population, report single or multiple episodes of zoster. These data are useful for consideration of immunosuppressive treatments and/or VZV and zoster vaccination. 相似文献

The development of agents that affect two or more relevant targets has drawn considerable attention in treatment of AD. Diallyl disulfide (DADS), an active principle of garlic, has been reported to prevent APP processing by amyloidogenic pathway. Recently, we have reported a new series of DADS derivatives and our findings revealed that compound 7k and 7l could provide good templates for developing new multifunctional agents for AD treatment. Thus, the present study was constructed to investigate the neuroprotective effect of DADS analogues (7k and 7l) against Aβ-induced neurotoxicity in SH-SY5Y human neuroblastoma cells and in ameliorating the cognition deficit induced by scopolamine in rat model. The results indicated that compound 7k and 7l significantly inhibited Aβ1–42-induced neuronal cell death by inhibiting ROS generation. Moreover, they prevented apoptosis, in response to ROS, by restoring normal Bax/Bcl-2 ratio. Furthermore, it was observed that scopolamine-induced memory impairment was coupled by alterations in neurotransmitters, acetylcholinesterase activity and oxidative stress markers. Histological analysis revealed severe damaging effects of scopolamine on the structure of cerebral cortex and hippocampus. Administration of compounds 7k and 7l at 5 mg/kg significantly reversed scopolamine-induced behavioural, biochemical, neurochemical and histological changes in a manner comparable to standard donepezil. Together the present findings and previous studies indicate that compounds 7k and 7l have neuroprotective and cognition-enhancing effects, which makes them a promising multi-target candidate for addressing the complex nature of AD. 相似文献

Infrequent but severe complications may occur during both diagnostic and therapeutic colonoscopy, including bleeding, perforation and sepsis. The most dangerous complication is perforation. Some iatrogenic perforations may be effectively managed by non-operative measures, but immediate surgery is most definitely indicated in order to minimise the morbidity and mortality associated with the complication. We report a case of colonoscopic perforation secondary to a therapeutic procedure, a snare polypectomy, successfully managed by laparoscopic repair using passing sutures and omentum fixation. The laparoscopic approach enables the surgeon to avoid an unnecessary laparotomy for an endoscopic complication. 相似文献
