Lindau disease is characterized by angioblastic lesions of the cerebellum and spinal cord. It may, rarely, be associated with pheochromocytoma. We describe the management of a patient with Lindau disease who was scheduled to undergo craniotomy for removal of a cerebellar hemangioblastoma and who developed severe hypertension following induction of anesthesia. Subsequent work up revealed a previously undiagnosed pheochromocytoma. The importance of recognizing a possible association between these two conditions is discussed. 相似文献

Background: There is a controversy regarding whether core stability exercise (CSE) is more effective than general exercise (GE) for chronic LBP. To compare different exercises regarding their effect on improving back strength and stability, performance of abdominal muscles is a useful index. Ultrasound imaging for measuring muscle thickness could be used to assess muscle performance. Objective: The aim of this study was to compare CSE and GE in chronic LBP using ultrasound imaging for measurement of thickness of the deep stabilizing and main global trunk muscles in non-specific chronic LBP. Methods: Each program included 16 training sessions three times a week. Using ultrasound imaging, four transabdominal muscle thickness were measured before and after the intervention. Disability and pain were measured as secondary outcomes. Results: After the intervention on participants (n = 43), a significant increase in muscle thickness (hypertrophy) was seen only in right and left rectus abdominis in the GE group, but significant difference to the CSE group was only on the right side. Disability and pain reduced within the groups without a significant difference in the change between them. Conclusions: The present results provided evidence that only GE increased right and left rectus muscle thickness. The only significant difference between CSE and GE groups was the right rectus thickness. As rectus is a global muscle, the effect of GE on strength improvement (one side stronger than the other) may have a negative effect on motor control of lumbopelvic muscles and possibly increase the risk of back pain occurring or becoming worse, though this was not observed in the present study. 相似文献

Background
Hemophilia is an inherited bleeding disorder. With proper treatment and self-care, persons with hemophilia can maintain an active, productive lifestyle. Hemophilia can be mild, moderate, or severe, depending on the degree of plasma clotting factor deficiency. The aim of the study was to assess the utility of ISTH-BAT in diagnosis, determining severity of the bleeding condition in newly diagnosed and known hemophilia patients, compare the bleeding score (BS) in adult and pediatric groups and investigate its association with plasma factor levels.Methods
ISTH-BAT was used to assess BS in a total of 115 patients, 78 with hemophilia A, and 37 with hemophilia B and in 100 controls.Results
BS was significantly higher in HA and HB patients as compared to controls, with no significant difference between HA and HB. The BS was very similar in newly diagnosed compared to known hemophilia patients, lower in pediatric compared to adult and higher in severe compared to mild HA patients.Conclusion
The ISTH BAT can help identify hemophilia patients. Therefore it is a useful tool to distinguish between affected and unaffected individuals with bleeding. Moreover, an important finding of our study is that there is no major difference between the scores in known and newly diagnosed patients. 相似文献5.

Toll like receptors are primary sensors of both innate and adaptive immune systems. They activate APCs and influence T-cell function in inflammatory autoimmune response. Studies have shown that TLR manipulation may lead to either tolerance or trigger autoimmunity. Using diabetogenic and subdiabetogenic multiple low doses of streptozotocin, we demonstrate here that Pam3 CYS-CK4 a TLR-2 agonist, enhances and promotes diabetes in C57BL/6 male mice following increased apoptosis of β islet cells. FACS analysis of isolated pancreatic lymph node cells revealed significant increased number of macrophages, dendritic cells, CD4+ TNF-α+, CD4+ IFN-γ+ and most significantly, CD4+ IL-17+ and reduced number of CD25+Fox p3+ T cells after Pam3CSK4 treatment. Genetic deletion of IFN-γ prevents whereas deletion of IL-17 reduced severity of Pam3CSK4-induced enhancement of diabetes. TLR-2 agonist-enhanced diabetogenesis is also influenced by enhanced influx of antigen presenting cells and suppression of regulatory T cell activity. 相似文献

In more than half of infertile men,the cause of their infertility is unknown.Several studies revealed the role of viral infections in male infertility.The aim of the present study was to determine the prevalence of herpes simplex virus-1 (HSV-1) and HSV-2 in semen from asymptomatic infertile male patients,and its association with altered semen parameters.A total of 70 semen samples were collected from infertile men who attended the Research and Clinical Center for Infertility in Yazd,Iran.Semen analysis and diagnostic real-time PCR using specific primers and probes for HSV-1 and HSV-2 DNA were performed.Comparison of semen parameters between virally infected and non-infected samples were performed with independent t-test and Mann-Whitney test.Semen analysis showed that infertile men fell into two groups,the male factor group and the unexplained group.HSV-1 and HSV-2 DNA was detected in 16 (22.9%) and 10 (14.3%) of 70 semen samples,respectively.All HSV-positive samples had abnormal semen parameters (the male factor group).Although HSV infection was not associated with sperm motility and morphological defects,it was correlated with lower sperm count in the seminal fluid.The findings suggest that asymptomatic seminal infection of HSV plays an important role in male infertility by adversely affecting sperm count. 相似文献

Purpose
Pregabalin is probably more effective than prototype gabapentin in different kinds of pain treatments. This study was performed to compare the potency of gabapentin, pregabalin, and morphine in a well-established model of visceral pain.Methods
The number of abdominal contractions was counted for 30 min in adult male mice that received different doses of pregabalin, gabapentin, morphine, or placebo intraperitoneally 30 min before receiving 0.6% acetic acid 10 mL·kg?1.The antinociceptive effect of each drug dose was determined as a percentage of the reduction in the number of acetic acid-induced writhes. The effective doses, for 20%, 50%, and 80% response (ED20, ED50, and ED80, respectively), of each drug were calculated using least squares linear regression analysis, and then dose-response curves were compared.Results
Pregabalin, gabapentin, and morphine produced a linear dose-dependent antinociceptive effect (coefficient of determination [r2] > 0.9). No difference was observed between slopes of dose-response curves. The ED50 estimates (95% confidence interval) for pregabalin, gabapentin, and morphine were 17.1 (12.9 to 22.1) mg·kg?1, 87.1 (45.8 to 129.8) mg·kg?1, and 0.2 (0.1 to 0.3) mg·kg?1, respectively.Conclusion
In this animal model of visceral pain, all three drugs exhibited parallel dose-response curves. Pregabalin had five times the potency of gabapentin and 1/85th the potency of morphine. Similar potency ratios may apply in clinical practice. Despite some limitations of animal studies, this model could be useful for comparing new analgesics in visceral pain treatment. 相似文献10.

BACKGROUND: Varicocele is the most common cause of male infertility. The etiology and pathophysiology of varicocele are multifactorial. When low sperm counts are associated with varicocele, varicocelectomy can partially restore spermatogenesis and fertility. Few recent studies have reported that in some varicocele cases, there may be an associated genetic etiology. Presence of a genetic factor like azoospermia factor microdeletions may lead to irreversible spermatogenic arrest in these cases, but very few reports support these findings. However, it is still not understood why some cases improve after varicocelectomy and why some cases show no improvement in semen parameters postoperatively. AIM: It is important to distinguish varicocele cases from Yq microdeletions as these cases have irreversible testicular damage and thus carry a poor prognosis after varicocelectomy. SETTINGS: Research and Referral tertiary care hospital. Design: Prospective study. MATERIALS AND METHODS: Seventy-two infertile men with varicocele were referred for Yq microdeletion analysis from the infertility clinic of AIIMS and Army Research and Referral Hospital. Genomic DNA was isolated from blood and polymerase chain reaction microdeletion screening was done in these cases to determine the presence or deletion of AZF loci. RESULTS: In this study 7 (9.7%) varicocele cases harbored Yq microdeletion. The sperm count in cases which harbored Yq microdeletion was significantly lower than in cases without Yq microdeletion. CONCLUSION: Varicocele cases with Yq microdeletion do not show improvement in semen parameters post-varicocelectomy. Detection of Yq microdeletion determines prognosis and future management in such cases. 相似文献
