Comparisons of emotional health by diagnosis among women with early stage gynecological cancers

ObjectiveTo assess self-reported emotional health in a cohort of women with early stage gynecologic cancers and to explore differences based on primary cancer type.MethodsWe analyzed survey data from a cohort study of gynecological cancer patients treated at an academic cancer center. Measures of emotional health included cancer-related quality of life, distress, depression, anxiety, posttraumatic stress disorder (PTSD), and posttraumatic growth. Univariate and multivariate linear regression models examined differences in emotional health measures by primary cancer site. Potential confounders considered for inclusion in the final models were age, stage, education, income, partner status, treatment status, and race.Results242 patients with early stage disease completed the survey. Patients with cervical and vaginal/vulvar cancers reported greater cancer-related distress, anxiety and PTSD symptoms. Patients with endometrial cancer reported the lowest posttraumatic growth scores, which remained statistically significant after adjustment for demographic and clinical differences. No significant differences in cancer-related quality of life were observed among individuals with different primary cancer sitesConclusionsThese data suggest patients with early-stage gynecologic cancer face different psychosocial sequelae based on primary cancer site, though underlying clinical and sociodemographic factors may play a significant role in this observed relationship. Further research is needed to assess poorer emotional health among individuals with vaginal/vulvar cancers and the lower posttraumatic growth among patients with endometrial cancer as posttraumatic growth is considered a potentially beneficial psychosocial outcome of cancer.     

Extracerebral paradoxical embolisms in patients with intracardiac shunts

BackgroundIntracardiac shunts are considered to play a role in cryptogenic ischemic stroke. However, data on paradoxical embolization into the peripheral arteries remains scarce. Since passage of the emboli through an intracardiac shunt is considered to be the possible etiological mechanism, identification of the presence of a venous thrombus and its migration via the cardiac shunt are essential to confirm this pathogenic mechanism. However, both of these essential components are often difficult to establish due to various methodological and temporal issues.MethodsVarious factors limiting the diagnostic methods of intracardiac shunts are discussed.ResultsThe diagnostic criteria for intracardiac shunt should be aimed at looking into both cerebral as well as peripheral arterial beds. Utilizing the quantitative grading scales may help in a better assessment of the intracardiac shunts.ConclusionsQuantification of the intracardiac shunt and its “functional potential” should be considered an individuals' preferential predisposition for the involvement of various arterial beds. This would help in a better understanding of the complex relationship between intracardiac shunts and various systemic embolic phenomena and planning for a definitive treatment.     

Observations on the assessment and optimal use of videolaryngoscopes

Due to the large number of videolaryngoscopes now available, it might be difficult for novice users to assess the various devices or use them optimally. We have collated the experiences of several airway management experts to assist in the assessment and optimal use of seven commonly used videolaryngoscopes. While all videolaryngoscopes have unique features, they can be broadly divided into those inserted via a midline approach over the tongue and those inserted laterally along the floor of the mouth. Videolaryngoscopes that are placed on the floor of the mouth displace the tongue antero-laterally and flatten the submandibular tissues. They generally require a conventional shaped bougie for tracheal intubation. Videolaryngoscopes that use the midline approach may have an in-built airway conduit for the tracheal tube or may require a 'J-shaped' stylet in the tracheal tube to negotiate the upper airway. This may cause difficulty when the tracheal tube is inserted through the glottis and the tip abuts the anterior wall of the subglottic space. Knowledge of the mechanism used by videolaryngoscopes to achieve laryngoscopy is essential for safe and successful tracheal intubation when using these devices.     

Enhancing cosmesis in laparoscopic colon and rectal surgery

PURPOSE: The only unanimously accepted advantage of laparoscopic colon and rectal surgery, at present, is cosmesis. Techniques to enhance cosmesis in laparoscopic surgery are presented. METHOD: Careful and meticulous placement of laparoscopic ports and incisions enhance the cosmetic effect of the procedure. Determination of port sites is aided, in part, by preoperative assessment of natural skin folds and creases by a stomatherapist. Intraoperative techniques include placement of ports directly through the umbilicus, previous incisions, and natural skin folds and creases. RESULTS: These techniques have been practiced with no complications or added morbidity. Safety and good access during the procedure is not compromised. The cosmetic effect in laparoscopic surgery is enhanced. CONCLUSION: Techniques to enhance cosmesis in laparoscopic surgery can be practiced safely and efficiently. Surgeons should make an effort to focus on this benefit, when possible.     

Pudendal neuropathy is not related to physiologic pelvic outlet obstruction

Chronic straining because of pelvic outlet obstruction is hypothesized to cause pudendal neuropathy (PN) by stretch injury. PURPOSE: The aim of this study was to determine any association between PN and pelvic outlet obstruction. METHODS: One hundred forty-seven constipated patients were evaluated by cinedefecography and pudendal nerve terminal motor latency assessment. PN was defined as a latency longer than 2.2 ms. Pelvic outlet obstructive patterns of evacuation included paradoxic contraction, nonrelaxation of the puborectalis muscle, or failure of opening of the anal canal. RESULTS: Median length of constipation including straining during evacuation was eight (range, 1–47) years. Ninety-one (62 percent) subjects had a normal pattern of evacuation, and 56 (38 percent) had an obstructed pattern. Both groups had a similar median age (68 tvs.69 years, respectively;P>0.05) and same median length of symptoms. Overall incidence of PN was 23.8 percent (10.9 percent unilateral and 12.9 percent bilateral). There was no difference in the incidence of PN between patients with normal evacuation and patients with obstructed evacuation (24.2 percent vs.23.2 percent, respectively;P>0.05). Patients with PN had a similar incidence of physiologic pelvic outlet obstruction as did patients without PN. However, median age of patients with PN was higher than those without PN (73 tvs.66 years, respectively;P>0.05). CONCLUSION: There was a difference in the incidence of PN between normal and obstructed patterns of evacuation. Therefore, the espoused theory that obstructed defecation causes PN appears flawed.Dr. Carlos Vaccaro was a research fellow from the Section of Colon and Rectal Surgery, Department of Surgery, Italian Hospital, Buenos Aires, Argentina.Poster presentation at the meeting of The American Society of Colon and Rectal Surgeons, Orlando, Florida, May 8 to 13, 1994.     

Alpha-synuclein mRNA expression in sporadic Parkinson's disease.

The expression of alpha-synuclein gene can be influenced by the genomic load and/or epigenetic factors. By using quantitative real-time polymerase chain reaction techniques, we demonstrated that the alpha-synuclein gene mRNA expression in sporadic PD did not differ from healthy controls (median [range] 0.110 ]0.012-0.628] vs. 0.120 [0.028-0.447]; P = 0.15). There was no difference in the alpha-synuclein gene dosage between PD patients with high and low mRNA expression. Multivariate analysis did not reveal age, gender, or cigarette smoking as confounding variables. Our study suggests that there was no significant alteration of alpha-synuclein mRNA expression in our sporadic PD patients compared to controls. However, the role of alpha-synuclein mRNA expression in select groups of sporadic PD patients and its interaction with environmental agents need to be further determined.
