Conjunctival flap advancement with or without scleral graft for hypotony maculopathy after trabeculectomy

AIM: To introduce a novel technique for transscleral fixation of the PC-IOL that requires no sutures on the IOL haptics. METHODS: Instead of suturing polypropylene onto the IOL haptics, the method simply winds the thread on the haptics. Fifteen eyes of 15 patients underwent this technique and were followed up for more than 18 months. Surgical outcomes and post-operative complications were evaluated and compared with those of the conventional transscleral fixation method. RESULTS: Postoperative cylinder was significantly lower in the thread winding group than in the conventional transscleral fixation method group (-1.02±0.46 diopters vs -1.57±0.77 diopters; P=0.01). Further, no postoperative complications, such as optic capture, IOL dislocation, and hyphema, were detected in the thread winding group. CONCLUSION: We believe that our thread winding technique is better than previously reported methods because it is simple, mechanically stable, and free from suture-related complications.     

Three-dimensional human pattern visual evoked potentials. II. Multiple sclerosis patients.

Pattern visual evoked potentials were obtained from 46 patients with definite relapsing/remitting multiple sclerosis, using both a conventional 5-channel occipital array and a 3-D recording technique consisting of three bipolar derivations approximating the three dimensions of space. These three orthogonal wave forms were displayed as a 3-D Lissajous trajectory for each subject. Two of the 15 patients with completely normal conventional pattern VEPs had abnormalities of the orientation of the B-C curvilinear segment of the 3-D pattern VEPs. Delays in the first major occipital positive component (P100) were evident using both techniques; the correlation between P100 latency and the latency of the corresponding trajectory apex was r = 0.99 (P less than 0.01). Post-chiasmal MRI abnormalities were associated with 3-D VEP orientation abnormalities. Three-dimensional pattern VEPs are moderately more sensitive than conventional pattern VEPs at detecting dysfunction posterior to the optic chiasm in demyelinating disease and do not require the use of eccentric fixation to do so.     

The course of pregnancy among mothers above 35 years and its outcome in Kafr-El-Zayat.

A group of pregnant mothers above 35 years old were collected from the MCH centre in Kafr-El Zayat during a period of 10 months (82). A control group of mothers aged 20-30 years old were also selected during the same period (62). Those with specific diseases from both groups were excluded. During the repeated visits of those mothers to the MCH centre they were subjected to complete history taking, physical examination plus urine analysis & haemoglobin levelling. A special visit was performed by the researcher to the mothers on 7th day after labour to report on the outcome of labour. The present study revealed significant differences between mothers over 35 years and those of 20-30 years in the course of pregnancy, labour and their outcomes where the former group showed greater tendency to be at a higher risk.     

School-Based Cardiovascular Health Promotion: The Child and Adolescent Trial for Cardiovascular Health (CATCH)

The Child and Adolescent Trial for Cardiovascular Health (CATCH) is a multisite intervention research study that builds on significant progress made in school health education research in the 1980s. The study has three phases: Phase I deals with study design, intervention, and measurement development, Phase II involves the main trial in 96 schools in four states, and Phase III focuses on analysis. The intervention program targets third-fifth grade students and focuses on multiple cardiovascular health behaviors, including eating habits, physical activity, and cigarette smoking. Classroom curricula, school environmental change, and family involvement programs are developed for each grade level and behavioral focus. This paper describes Phase II of CATCH with a rationale for cardiovascular health promotion with youth. The process of change that appears to be necessary for school-based health promotion and that will be tested in CATCH are presented as a framework to guide these efforts.     

How we do it: Implementing change – a multi‐centre audit of an evidence‐based protocol on post‐thyroidectomy calcium maintenance

? Our previous retrospective audit (Clinical Otolaryngology, December 2004) identified considerable variation in post‐thyroidectomy calcium assessment. This led to a well‐structured protocol. ? The protocol was introduced into two trusts. The results were prospectively collated for 64 thyroid procedures over a period of 6 months. ? All patients that warranted it were tested on day 1, and 71% were tested on day 2 – highlighting a more structured approach, and avoiding unnecessary vene‐ puncture in all thyroid lobectomy patients. ? Such protocols have been proven to be an important tool in the effort to improve the quality and lower the cost of care. ? Resistance to change, established practise and lack of data collection resources prevented this protocol from becoming established in more regional trusts.
