FFT-based digital tactile vocoder system for real-time use

A microprocessor-based real-time digital vibrotactile vocoder system has been developed to train the deaf and for artificial hearing research. The system is composed of a microcomputer module with a digital signal processor interface units and an attenuator/driver circuit. Live or digitised (stored or synthetic) speech is presented to the skin spectrally through a belt housing eight or 16 vibrators. Speech is processed in real time using a fast Fourier transform. The system is also capable of presenting any arbitrary spatiotemporal pattern on the skin for artificial hearing experiments. A preliminary experiment with a deaf subject indicates that the system is potentially an effective device for artificial hearing.     

The Efficacy of Fluoxetine in the Treatment of Premature Ejaculation: A Double-Blind Placebo Controlled Study

Purpose

The efficacy of the selective serotonin re-uptake inhibitor fluoxetine in the treatment of premature ejaculation was examined.

Materials and Methods

The study comprised 17 patients with premature ejaculation who presented to the urology clinic of our medical school. In this double-blind study the patients were randomized into treatment groups receiving 20 mg. fluoxetine daily for 1 week and 40 mg. daily afterward (group 1) or 1 capsule placebo daily for 1 week and 2 capsules daily afterward (group 2). The groups were evaluated according to the latent period of intravaginal ejaculation.

Results

The latent period of intravaginal ejaculation in group 1 was significantly longer than that in group 2. Nausea, headache and insomnia were reported side effects.

Conclusions

Fluoxetine may be regarded as a safe and effective alternative in the treatment of premature ejaculation.     

The long-term outcomes of persistent childhood allergic asthma: A cross-sectional study from western Anatolia: Childhood persistent asthma in western Anatolia

BackgroundProspective cohort studies have provided useful knowledge about the natural history of asthma. However, most of the studies are conducted in western countries but the course of the disease and long-term outcomes may differ between countries due to environmental and cultural factors.ObjectiveThe aim of this study is to describe the long-term outcomes of childhood asthma, with data from a follow-up study of at least 10 years, in western Anatolia, Turkey.MethodsFifty-two patients diagnosed with persistent allergic asthma participated in the study. The patient's demographics, findings on admission, age at onset of disease, time of diagnosis, history of other allergic conditions, history of parental asthma and allergic disorders, presence of pharmacotherapy and immunotherapy were obtained from patients’ records. The factors influencing remission at the end of 10 years follow-up were evaluated.ResultsA total of 20 patients (38.5%) were on remission at the end of 10 years. The type of allergen, multi-allergen sensitivity, eosinophilia and elevated serum immunoglobulin E on admission, accompanying allergic disorders and atopy in parents, and allergen immunotherapy did not affect the remission rate (p > 0.05).ConclusionChildhood persistent asthma is not a homogeneous clinical entity but high clinical remission rates are obtained in western Anatolia. There is no significant predictor of clinical remission in long term follow-up. Prospective studies should be performed in larger asthmatic populations to obtain further data about the natural course of childhood asthma.     

Overcoming the organization–practice barrier in sports injury prevention: A nonhierarchical organizational model

The organization of sports at the national level has seldom been included in scientific discussions of sports injury prevention. The aim of this study was to develop a model for organization of sports that supports prevention of overuse injuries. The quality function deployment technique was applied in seminars over a two‐season period to develop a national organizational structure for athletics in Sweden that facilitates prevention of overuse injuries. Three central features of the resulting model for organization of sports at the national level are (a) diminishment of the organizational hierarchy: participatory safety policy design is introduced through annual meetings where actors from different sectors of the sporting community discuss training, injury prevention, and sports safety policy; (b) introduction of a safety surveillance system: a ubiquitous system for routine collection of injury and illness data; and (c) an open forum for discussion of safety issues: maintenance of a safety forum for participants from different sectors of the sport. A nonhierarchical model for organization of sports at the national level – facilitated by modern information technology – adapted for the prevention of overuse injuries has been developed. Further research is warranted to evaluate the new organizational model in prospective effectiveness studies.     

Obstructive sleep apnea syndrome and chronic kidney disease: a new cardiorenal risk factor

Clinical and experimental studies revealed that sleep apnea might be an insidious risk factor for the progression of kidney disease and development of cardiovascular events by exacerbating well-known risk factors, namely hypertension, type 2 diabetes mellitus and obesity. Furthermore, sleep apnea also has a negative impact on endothelial function. Therefore, sleep apnea might be defined as a new cardiorenal risk factor. In this review, we aimed to summarize the evidences supporting the complex inter-relations between sleep apnea and development and progression of chronic kidney disease.
