In case of severe blepharoptosis, frontalis muscle suspension with fascia or frontalis transfer has been popular for decades, but these static procedures have some disadvantages such as lagophthalmos, lid lag and remnant ptosis. Twenty-six patients with severe blepharoptosis who underwent frontalis suspension, frontalis transfer, or levator resection at Yonsei University Severance Hospital from 1980 to 1988 were studied. The follow-up period of patients ranged from 10 to 18 years with a mean of 12 years. Surveys and clinical results were obtained, In our review of postoperative complications, lagophthalmos persisted in sleep and even in forced eye closure in most patients 2 to 6 months after operation. But no recurrence was noted. In conclusion, undercorrection of ptosis is more desirable than overcorrection. As well levator resection can be considered in selected cases to prevent complications.

The reconstruction of soft tissue defects with open fracture around the knee joint is limited by its unique location. Free tissue transfer is hindered by the selection of the recipient vessel and problems of microsurgery. The arc of rotation, defect size, and location must be taken into consideration in the use of regional muscle transfer such as gastrocnemius. According to Mathes et al, the flap survival can be enhanced by selective division of the dominant segmental pedicles, only a part of which can normally be transposed safely on its minor segmental pedicle. Neovascularization, vascular proliferation, and dilatation have also been produced by the delay procedure using silicone sheets. The authors have used the delay procedures with wrapping of the gracilis or sartorius muscle which enabled distally-based transposition of these muscles. The method showed satisfactory outcome in resurfacing the wound around the knee joint. The indictions for this procedure were defects of moderate size and those difficult to reach with conventional muscle flaps. The flap could reach the upper one-third of the lower leg. Other merits are relative simplicity and reliability without significant extension of hospital stay. The drawbacks are the two operative procedures necessary and the risk of infection due to silicone sheets.

BACKGROUND:Metronome guidance is a feasible and effective feedback technique to improve the quality of cardiopulmonary resuscitation (CPR). The rate of the metronome should be set between 100 to 120 ticks/minute and the speed of ventilation may have crucial effect on the quality of ventilation. We compared three different metronome rates (100, 110, 120 ticks/minute) to investigate its effect on the quality of ventilation during metronome-guided 30:2 CPR. METHODS:This is a prospective, randomized, crossover observational study using a RespiTrainer?r. To simulate 30 chest compressions, one investigator counted from 1 to 30 in cadence with the metronome rate (1 count for every 1 tick), and the participant performed 2 consecutive ventilations immediately following the counting of 30. Thirty physicians performed 5 sets of 2 consecutive (total 10) bag-mask ventilations for each metronome rate. Participants were instructed to squeeze the bag over 2 ticks (1.0 to 1.2 seconds depending on the rate of metronome) and deflate the bag over 2 ticks. The sequence of three different metronome rates was randomized. RESULTS:Mean tidal volume significantly decreased as the metronome rate was increased from 110 ticks/minute to 120 ticks/minute (343±84 mL vs. 294±90 mL, P=0.004). Peak airway pressure significantly increased as metronome rate increased from 100 ticks/minute to 110 ticks/minute (18.7 vs. 21.6 mmHg, P=0.006). CONCLUSION:In metronome-guided 30:2 CPR, a higher metronome rate may adversely affect the quality of bag-mask ventilations. In cases of cardiac arrest where adequate ventilation support is necessary, 100 ticks/minute may be better than 110 or 120 ticks/minute to deliver adequate tidal volume during audio tone guided 30:2 CPR.

There are many variant forms in Klinefelter's syndrome which is characterized by azoospermia, gynecomastia, a variable degree of enuchoidism, elevated urinary gonadotropins, atrophic testis and hyalinization of the seminiferous tubules. Among these, 48XXXY from is known as rare variants of Klinefelter's syndrome which had been reported about 50 cases. 48 XXXY Klinefelter's syndrome is composed of more severe physical abnormality and more multiple symptom and signs than classic Klinefelter's syndrome. We have reported a case of 48 XXXY Klinefelter's syndrome associated with ophthalmic problems and mild mental retardation in 20 year old Korean male.

7.Vitreous Vascular Endothelial Growth Factor Concentration In Various Vitreoretinal Disorders.
Journal of the Korean Ophthalmological Society 2002;43(1):96-103
PURPOSE: Vascular endothelial growth factor (VEGF) has been identified as an endothelial cell-specific angiogenic factor of intraocular neovascularization, a pathologic complication of many vitreoretinal disorders. We studied to evaluate clinical correlation of intravitreal VEGF concentration and various vitreoretinal disorders. METHODS: Forty eight vitreous fluid samples were obtained at the time of vitreoretinal surgery from 43 patients of various disorders. Concentrations of VEGF1 6 5 in vitreous fluid were determined by Human VEGF ELISA kit and its correlation with diabetes, intraocular hemorrhage, neovascularization, proliferative vitreoretinopathy, retinal detachment, pan retinal photocoagulation, and postoperative condition was statistically analyzed. RESULTS: Intravitreal concentrations of VEGF in case of intraocular hemorrhage (0.809+/-1.467 ng/ml), neovascularization (1.167+/-1.656 ng/ml), and anterior segment neovascularization (2.381+/-2.043 ng/ml) were significantly high (P<0.05). CONCLUSIONS: VEGF plays a major role in the development of neovascularization in the various retinal disorders.

OBJECTIVES: This study was performed to determine the self-perceived fatigue and its association with job stress and psychosocial factors among white collar male workers. METHODS: The self-administered questionnaires were given to 872 workers employed in 42 work places located in Daejeon City and Chungnam Province during the period from February 1st to April 30th, 2009. The questionnaire surveys included socio-demographic characteristics, job-related characteristics, health-related behaviors, a Job Content Questionnaire (JCQ), psychosocial factors (type A behavior pattern, locus of control, self-esteem) and the Multidimensional Fatigue Scale (MFS). RESULTS: Concerning the correlation of self-perceived fatigue with various factors, while the level of self-perceived fatigue was positively correlated with the job demands, a type A behavior pattern and self-esteem, it was negatively correlated with job autonomy and supervisor support. With the analysis of the covariance structure, JCQ (job demand, job autonomy, supervisor support and coworker support) had more of an influence on the level of self-perceived fatigue than the psychosocial factors (type A behavior pattern, locus of control, self-esteem). The inter-relational effects were that the higher the JCQ and psychosocial factors, the higher the level of self-perceived fatigue. CONCLUSIONS: The study results indicated that the level of self-perceived fatigue was more influenced by the JCQ than the psychosocial factors. Thus, an effective strategy for fatigue reduction among workers requires additional programs that will focus on innovated job specifications and managed psychosocial factors.

PURPOSE: An in vivo study compared the effect of oral antibiotic ingestion to that of intraprostatic antibiotic injection in a rat model of chronic bacterial prostatitis. MATERIALS AND METHODS: Wistar rats were divided into four experimental groups: oral phosphate buffered saline (PBS) ingestion group (Op group), oral antibiotic ingestion group (Oa group), intraprostatic PBS injection group (Ip group) and intraprostatic antibiotic injection group (Ia group). Escherichia coli Z17 (O2:K1:H ) was inoculated to the prostatic urethra of the 4 experimental groups to develop the chronic bacterial prostatitis rat model. To confirm the chronic bacterial prostatitis, urine bacterial culture, tissue bacterial culture and histopathologic examinations were conducted 4 weeks after inoculation of E. coli. PBS and oral ciprofloxacin were administered orally twice a day for 1 week to the Op and Oa groups, respectively, and were injected into the prostate in the Ip and Ia groups, respectively. Urine bacterial culture, tissue bacterial culture and histopathologic examinations were conducted with specimens obtained 5 weeks after inoculation of E. coli. RESULTS: Microbiological culture of urine demonstrated that there was no significant difference among any of the four experimental groups (p>0.05). Microbiological culture of the prostate demonstrated that the mean Log10cfu/g of the Ia group was significantly lower than that of the other three experimental groups (p<0.05). The histopathology showed resolving prostatitis in the intraprostatic antibiotic injected groups compared with the other experimental groups. CONCLUSIONS: This study indicates that the effect of intraprostatic antibiotic injection for chronic bacterial prostatitis was more positive than oral antibiotic ingestion. This result suggests that intraprostatic antibiotic injection would be a treatment modality to overcome the difficulty of passage of antibiotics across blood-prostate barrier into the prostatic tissue.
