Methods to Manage Intra-operative Floppy-iris Syndrome and Poor Pupil Dilation in Cataract Surgery...

Management of Intraoperative Floppy-iris Syndrome and Small Pupils With Different Mechanical Devices

Cataract surgery is one of the most frequently performed surgeries worldwide and complications are rare. However, there are factors that increase the risk of complications, such as poor pupil dilation and intra-operative floppy iris syndrome (IFIS). Reasons for a small pupil size are pseudoexfoliation syndrome (PXF) syndrome, uveitis or synechia and the use of pilocarpin drops. IFIS is a syndrome usually caused by systemic alpha1-blockers (foremost tamsulosin) used to treat benign prostatic hyperplasia.1,2 As described by Chang and Campbell3 IFIS is characterized by billowing of a flaccid iris stroma, a propensity for iris prolapse towards the phacoemulsification tip as well as towards the incisions and progressive intra-operative pupil constriction. Stopping tamsulosin pre-operatively did not show to effectively prevent IFIS.4,5 However, it is of high importance to identify patients prior to surgery, who are treated with alpha1-blockers, or patients with a small pupil size and poor pharmacological pupil dilation. Some methods, such as intracameral injection of phenylephrine is only sufficient in a few cases 6, and a disadvantage is the risk of a hypertensive episode.7 Another pharmacological method is the use of atropine drops pre-operatively, but this method did not show to sufficiently reduce IFIS.4 Different methods were shown to reduce intra-operative problems due to IFIS/small pupil size: The use of highly cohesive ophthalmic viscosurgical devices (OVD), also called viscoadaptives, such as sodium hyaluronate (e.g. AMO Healon5 or Croma Eyefill H.D.) help to viscodilate the pupil and by resting on the iris during the entire phacoemulsification procedure reduce the risk of iris prolapsing towards the incisions. This method is more dependent on a central phacoemulsification technique and low fluidic parameters to allow the OVD to stay on the iris during the entire procedure.8 In case of a small pupil, pupil stretching with 2 instruments can be used additively. Another option to stabilize the pupil size is the use of mechanical pupil expansion devices, such as Iris retractors - these devices are routinely used to dilate the pupil intra-operatively. Typically, 4 or 5 iris retractors, also called iris hooks, are inserted through 4-5 incisions. Usually, the IFIS pupil is very elastic and the risk of overstretching is small.8 Pupil expansion rings, such as the Malyugin ring. This ring is placed on the pupil margin with an injector through the main incision. It eliminates the need of additional incisions and saves time.9 Rationale To compare different methods to manage IFIS and poor pupil dilation in cataract surgery: a pupil expansion ring (Malyugin Ring), iris retractors (iris hooks) and a viscoadaptive OVD.

The Effect of Acupuncture on Insulin Sensitivity Polycystic Ovary Syndrome

Polycystic Ovary SyndromeInsulin Resistance

Hyperinsulinemia and insulin resistance play a key role in the pathogenesis of polycystic ovary syndrome (PCOS). Insulin resistance is significantly associated with the long-term risks of metabolic syndrome and cardiovascular disease. Acupuncture with electrical stimulation has in rats with dihydrotestosterone (DHT)-induced PCOS been shown to improve insulin sensitivity. Whether these findings can be translated into women with PCOS has not been investigated. Therefore, this study aims to evaluate whether acupuncture improves insulin sensitivity, ovulation rate and quality of life in women with PCOS. Our hypothesis is that acupuncture with combined manual and low-frequency electrical stimulation of the needles improves insulin resistance, induces ovulation and improves quality of life.

Family-based Intervention for Youth With Prader-Willi Syndrome: The Active Play at Home Study

Prader Willi SyndromeChildhood Obesity

Compared to other children, those with disability have additional challenges to being physically active. Prader-Willi Syndrome (PWS) is a genetic form of childhood obesity that is characterized by hypotonia, growth hormone deficiency, behavioral, and cognitive disability. In children, the low prevalence of PWS (1 in 10,000 to 15,000 live births) makes group-based physical activity (PA) interventions impossible. In contrast, the home environment presents a natural venue to establish a PA routine for this population. The present high prevalence of non-syndromal childhood obesity (one in four) and high physical inactivity rates, make alternative approaches to increasing PA in this population an area of high interest. Therefore, we have developed a 24-week home-based physical activity that could be suitable for children and adolescents ages 8-15 with PWS as well as obese children without PWS ages 8-11 years. It is hypothesized that: 1) an age-appropriate 24-week home-based PA intervention will increase PA levels in youth with PWS and without the syndrome but with obesity; 2) motor proficiency, central sensory reception and integration, and body composition will significantly improve in youth with and without PWS following completion of the home-based PA intervention and 3) physical activity self-efficacy and quality of life will increase significantly in youth with and without PWS who complete the home-based PA intervention. The study participants are 115 youth ages 8-15 y (45 with PWS and 70 without PWS but categorized as obese). The study utilizes a parallel design with the wait-listed control group receiving the intervention after serving as control. Participants are expected to complete the PA curriculum 4 days a week for six months including playground games 2 days a week and interactive console games 2 days a week. Parents are trained at baseline and then provided with a PA curriculum (Active Play at Home) and equipment to guide their implementation of the program at home. Measurements of children and parent dyads are assessed at baseline and at the end (week 24) of the intervention or control periods. Outcome measures include PA, body composition, motor proficiency, central sensory reception and integration (subsample of children only), quality of life and physical activity self-efficacy. PA intervention compliance is monitored using mail-in daily self-report checklists.

Sleep Apnea Syndrome and Vitamin D

Obstructive Sleep Apnea-hypopnea Syndrome

Obstructive sleep apnea/hypopnea syndrome (OSAHS) is a highly prevalent disorder with multiple comorbidities. OSAHS is characterized by repetitive episodes of airflow reduction (hypopnoea) or cessation (apnoea) due to upper airway collapse during sleep. Its major risk factor is obesity. However, its pathogenesis is complex and multifactorial. Reduced upper airway muscle tonus and/or unstable neuromuscular output seem to be involved in this collapsus. A normal vitamin D status is necessary for normal muscle function and neuromuscular output. As obesity is associated with a high rate of hypovitaminosis D, it appears of interest to evaluate the effect of vitamin D supplementation on OSAHS patients with vitamin D deficiency.

Therapeutic Monitoring of Metformin in Women With Polycystic Ovary Syndrome

Polycystic Ovary Syndrome

Metformin is one of the most commonly prescribed drugs worldwide for the treatment of Type 2 Diabetes. It has been currently used for the treatment of: polycystic ovary syndrome, gestational diabetes, metabolic syndrome and obesity. In patients with polycystic ovary syndrome (PCOS) the adverse side effects are a frequent cause for treatment discontinuation. In every day medical practice lower doses of Metformin are administered searching for the continuation of the treatment. However, there is no clinical study to support this assertion. The objective of this study is to monitor and correlate the therapeutic effect of Metformin on patients with PCOS taking daily doses of 1500mg and 1000mg.
