Objective: Colorectal surgeons are frequently on call to provide help to gynecologists who are managing bowel problems that occur either during or following gynecological surgery. This is a retrospective analysis of a single surgeon's experiences associated with such instances. The analysis focuses on whether there have been any changes in referral patterns, surgical techniques and/or results. Materials and Methods: From July 1984 to June 2008, 282 patients were operated on by a single colorectal surgeon, for problems that were related to gynecology. These consisted of 137 patients operated on during the first 12-year period, from July 1984 to June 1996. During this first period, 85 patients were operated on for cervical cancer related problems, 39 patients were operated on for problems related to other gynecological malignancies and nine patients were operated on for iatrogenic bowel injury during surgery. During the second 12-year period, from July 1996 to June 2008, 145 patients were operated on. Of these, 85 patients were operated on for cervical cancer related problems, 44 patients were operated on for problems related to other gynecological malignancies and eight patients were operated on for iatrogenic bowel injury during surgery. Results: During the first 12-year period, six operations were pelvic exenterations for primary gynecological malignancies or recurrences. One hundred and one patients received stomas during their first operation. Twenty-five patients encountered various complications. Postoperative death occurred in five patients. During the second 12-year period, 12 operations were pelvic exenterations for primary gynecological malignancies or recurrences. Eighty-seven patients received stomas during their first operation. Thirty-seven patients encountered various complications. Postoperative death occurred in six patients. Conclusion: Gynecological problems frequently involve the colon or rectum. Cervical cancer related problems remain the most common type necessitating help from a colorectal surgeon. In spite of advances in surgical management, stomas are still frequently unavoidable in order to cure a patient or improve the patient's quality of life. Appropriate management of problems by a colorectal surgeon in relation to gynecology is important and in the best interests of the patient. © 2012.

Previous experiments demonstrated that transgenic mice carrying both amyloid precursor protein and mutant ATP7B transgenes reduce amyloid plaques and diminish plasma Aβ levels. These experiments showed that a structural change of ATP7B may affect Alzheimer's disease (AD) susceptibility. In this study three missense SNPs in ATP7B gene (rs1801243, rs1801244, and rs1801249) were chosen to test whether they were associated with AD. We tested this hypothesis using a case control design. The experimental data showed that there was a significant deviation from Hardy-Weinberg equilibrium (HWE) for SNP rs1801249 (c.3419 T>C, Val1140Ala) in the case group (p = 0.014) but not in the control group and that there was an association between SNP rs1801249 and AD under a recessive model (p = 0.003). The data also showed that the genotype frequency distribution of the ATP7B c.1366 G>C polymorphism (rs1801244, Val456Leu) differed significantly between the AD patients and the normal subjects (p = 0.012). In addition, the frequency of the TGC haplotype of SNPs rs1801243, rs1801244, and rs1801249 was significantly higher in the AD patients compared with the normal subjects (p = 8.49×10-7). These observations suggested that genetic variations in the copper transporter gene ATP7B might contribute to AD pathogenesis in the Taiwanese population. Copyright © by BIOLIFE, s.a.s.

This report describes cerebral aneurysmal rupture with asymmetry of ipsilateral dural sinus hypoplasia using quantitative color-coded l-Flow cerebral venography to identify the venous pressure gradient. We suggest the pressure gradient may be a potential factor in cerebral aneurysmal rupture. We used I-Flow quantitative cerebral venography to measure the venous pressure gradient during acute cerebral aneurysmal rupture and post embolization in a 67-year-old woman who presented with clinical symptoms of left third nerve palsy for several days with mild headache initially without subarachnoid hemorrhage. We encountered a high venous pressure gradient of severe ipsilateral dural sinus hypoplasia during acute rupture of a posterior communicating aneurysm. Venous dural sinus asymmetry has been considered a congenital benign and non-pathological condition. However, this case may present severe hypoplasia of the dural sinus with potential pressure gradient in some unusual condition. A high venous pressure gradient may be another factor in cerebral aneurysmal rupture.

Defects in dopaminergic transmission play important roles in the disturbance of synaptic plasticity and even in advanced cognitive behavior. However, the relationship between genes involved in the regulation of dopamine levels and predisposition for Alzheimer's disease (AD) remains unclear. The potential association of dopamine-modulating gene polymorphisms with AD was evaluated. We performed a case-control study with 120 patients and 86 healthy controls. Two catechol-O-methyltransferase (COMT) single-nucleotide polymorphisms (SNPs) (rs2020917 and rs4646312), two dopamine D4 receptor (DRD4) SNPs (rs3758653 and rs916455), and four dopamine transporter (DAT1) SNPs (rs2937639, rs6347, rsl2516948 and rs11133762) were investigated. The T allele at the DRD4 SNP (rs3758653) was found to be significantly associated with AD. Our results also showed that haplotype frequencies, observed from the analyzed SNPs, were distributed significantly differently in AD patients vs control subjects. Moreover, a strong association was observed between the A allele at rs6347 of DAT1 and moderate stage of dementia. These observations suggest that genetic variations in the dopamine-modulating genes, COMT, DRD4 and DAT1, may contribute to AD pathogenesis in the Taiwanese population. Copyright © by BIOLIFE, s.a.s.

Amyloid peptide is thought to play a critical role in neuronal death in Alzheimer's disease (AD), most likely through oxidative stress. Free radical-related injury leads to DNA breaks, which subsequently activates the repair enzyme poly(ADP-ribose) polymerase-1 (PARP-1). In this study, the relationship between genetic variants situated at the PARP-1 gene and AD development was investigated. We performed a case and control study from a Taiwanese population enrolled 120 AD patients and 111 healthy controls by using a polymerase chain reaction restriction fragment length polymorphism approach for two PARP-1 exonic polymorphisms, 414C/T (rs1805404) and 2456T/C (rs1136410), corresponding to protein residues at positions 81Asp/Asp and 762Val/Ala. There were no significant differences in allele or genotype frequencies for either PARP-1 gene variant between the case and control groups; however, upon analysis of the haplotype distribution, four haplotypes (Hts) were identified. We found that the distributions of Ht3-TT and Ht4-CC were significantly associated with an increased risk of AD (P<0.0001), whereas the Ht1-TC haplotype showed a protective effect for cases compared with the control group (P<0.05). These results reveal that the PARP-1 gene is highly associated with AD susceptibility and might contribute to a critical mechanism that mediates cell survival or death as a response to cytotoxic stress. © 2010 Wiley-Liss, Inc.
