The fibrovascular tissues surrounding a glaucoma implant have been found to play a major role for the orbital absorption of aqueous humor following a glaucoma implant surgery. An ultrasonographic study was performed to investigate the ultrasonographic, characteristics of the tissues and its relationship with the postoperative intraocular pressure(IOP) control. Twenty-three eyes of 23 patients had undergone the e-PTFE membrane-silicone tube implantation and had been followed up for at least 6-month(mean +/- SD, 17 +/- 8.8 months). An ultrasonographic study for these eyes included such paramneters as presence of an aqueous reservoir surrounding the implant, size(height) of the aqueous reservoir and echoreHectivity from the reservoir wall tissues. The aqueous reservoir was identified in 22(96%) of 23 eyes and had a height varying from 1.0 mm to 5.5 mm. In eyes with an aqueons reservoir. 3 mm high or more, the IOPs were all 21 mmHg or less without further glaucoma medications(p=0.040, chi-square). In one eye with an obliterated reservoir on ultrasonography, the opening of the silicone tube was found to be occluded toward the extrascleral portion of the implant when reoperation was performed. The echo reflections from reservoir wall tissues were denser and higher comparing with those from the sclera of the respective eye in 7 eyes with a complete failure of postoperative lOP control(>or=30 mmHg on maximum medical theraph). These eyes also had and irregular echoreflections within the aqueous reservoir, which reflect an invasion of proliferating tissues into the reservoir.

Geotrichum(G.) candidum is a common fungus that is rarely pathogenic for man, first described by Link in 1809, and according to Dodge this fungus is classified as a subspecies of Eremnascaeae imperfectae. This species is largely saprophytic and is usually found in soil, decaying matters, and milk product, although isolation from skin, sputum, and feces of man is not unusual. Geotrichosis, caused by G. candidum may occur as an infection of the lung simulating chronic pulmonary tuberculosis or disseminated infection. Very rarely, skin and mucous membrane infection has been documented. These infections usually affect immunocompromised hosts. Literature concerning skin or soft tissue infection with this fungus is limited, especially in immunocompetent persons there are only a few reports by this organism. In this paper we report a case of cutaneous geotrichosis involving skin in a healthy woman, in which case steroid and trauma was supposed to play some roles in the pathogenesis.

High tibial osteotomy is a useful procedure in the treatment of early stage osteoarthritis of the knee which is confined to the medial compartment. But long term follow-up study of high tibial osteotomy has not been provided yet and its prerequisite for a successful result still remains unrevealed. Since the osteoarthritis can progress after the osteotomy, it may result in the loss of correction and recurrence of pain and require conversion to total knee replacement arthroplasty. We studied clinically and radiologically the long term result of high tibial osteotomy in 11 patients(16 knees) who had been treated at the Department of Orthopaedic surgery of Seoul Paik Hospital during the period from January, 1978 to May, 1989, and follow-up for longer than 4 years. Preoperative mean varus angle was 6.4 degrees and immediate postoperative mean valgus angle was 8.6 degrees and final mean valgus angle was 4.7 degrees. The average loss of correction angle was 3.9 degrees. At 2-year follow-up, the results of 16 knees were as follows; excellent in six knees, good in seven knees. The final results at average 7.2-year follow-up were excellent in four knees, good in six knees and one knee was converted to total knee replacement arthroplasty. The results showed deterioration of clinical results and loss of correction with time after osteotomy. However, in more than half of the cases the results were good or excellent at the final follow-up, We, therefore, conclude that high tibial osteotomy is still a useful procedure in osteoarthritis of the knee if performed with a precise surgical technique and an adequate overcorrection more than 10 degrees.

OBJECTIVE: The objectives of this study were to obtain information on MIS levels in normal and RDS neonates and to investigate the relationship between the RDS prevalence and MIS level in preterm and term neonates. METHODS: Total 131 male neonates were selected randomly and they were consisted of 50 term normal neonates, 15 term neonates with RDS, 50 prematurely born normal neonates, and 16 prematurely born neonates with RDS. Total 131 female neonates were also selected like male neonates. The venous blood was collected from all subjects and measured the level of MIS using ELISA. The ANCOVA was conducted to evaluate any influence of adjusted value of gestational age and body weight on MIS level between normal neonates and neonates with RDS. RESULTS: 1) The MIS levels of female neonates were significantly lower than those of male neonates with no overlap. 2) The MIS levels of normal female neonates were not significantly different from those of female neonates with RDS. 3) There were significant negative relationships between MIS concentration and gestational age (r=-0.777, p<0.001), and birth weight(r=-0.728, p<0.001) in normal rnale neonates. 4) There were significant negative relationships between MIS concentration and gestational age (r=-0.726, p<0.001), and birth weight(r=-0.725, p<0.001) in male neonates with RDS. 5) After adjusting the value of gestational age, the MIS level of male neonates with RDS was significantly higher than that of normal male neonates(p<0.001). 6) After adjusting the value of body weight, the MIS level of male neonates with RDS was significantly higher than that of normal male neonates(p<0.001). CONCLUSION: Male neonates with RDS had higher MIS levels than normal male neonates of the same body weight or same calculated gestational age. The results of this study suggest that MIS may play a causative or important ancillary role in the sexual dimorphism that characterizes the neonatal RDS and may be used as a predictive marker of RDS in male neonates.

There are few reports on intraneural ganglion, and this malformations mainly occurs in peripheral nerves of the upper and lower extremities. In the lower extremity, it often occurs in the common peroneal nerve, with neurologic symptoms such as motor weakness and sensory changes. We experienced a case of intraneural ganglion of the common peroneal nerve around the fibular head and this was associated with neurologic symptoms, including weakness of the motor power in the ankle and great toe dorsiflexion and sensory change in the foot dorsum. It was successfully treated by complete excision. We report here on this unusual case and we review the relevant literature.

BACKGROUND: Psychosocial stress and stressful events in life have been reported to be closely related to the onset and acute exacerbation of some dermatologic disorders, such as alopecia areata, psoriasis, seborrheic dermatitis and atopic dermatitis. However, the nature of the association between stress and dermatologic disorders remains unclear. OBJECTIVE: The purpose of this study is to determine the relation of stress and the onset and exacerbation of dermatologic disorders. Furthermore we studied whether the coping strategies to stress are related to dermatologic disorders. METHOD: We examined 30 patients with alopecia areata, 30 patients with androgenetic alopecia who visited Dept. of Dermatology, Chung-Ang University Hospital and a control group of 30 who visited our clinic at the same time for tinea pedis and onychomycosis, which are supposed not to be related to stress. For the evaluation of stress we used questionares of 'Scale of Life Events' and 'Multidimensional Coping Scale'. RESULT: 1) The score of life event stress in the alopecia areata group was significantly higher than that of the normal control group. The score of life event stress in androgenetic alopecia was higher than that of the normal control group with no statistical significance. 2) In the aspect of coping strategies, the alopecia areata group was significantly higher than the normal control group at the passive withdrawal and fatalism, while in the normal control group, emotional pacification, positive comparison and religious seeking tended to be higher than the alopecia areata group. In the androgenetic alopecia group, no significant pathologic coping strategies were found compared with the control. CONCLUSION: These findings suggest that the psychosocial stress may play a role in the pathogenesis of alopecia areata and androgenetic alopecia. But to clarify the exact role of stress, further studies about biological parameters of physiologic changes to stress are needed in the future.

Purpose: Only a few Asian studies have discussed the impact of statin intensity on clinical outcomes in patients with peripheral artery disease (PAD). We aimed to investigate the clinical impact of statin intensity in patients with PAD after endovascular revascularization. Materials and Methods: From April 2009 to June 2019, 376 patients with lower extremity PAD treated with endovascular revascularization were enrolled. They were classified into three groups according to statin intensity: no-statin, low-to-moderate intensity (LMI), and high-intensity (HI). The primary outcomes were major adverse cardiovascular events (MACE) and major adverse limb events (MALE). Results: During the 40-month follow-up, MACE occurred less frequently in the HI and LMI groups than the no-statin group (11.4% vs. 16.0% vs. 39%, p<0.001). In adjusted Cox models, the HI group had the fewest MACE [hazard ratio (HR): 0.447; 95% confidence interval (CI): 0.244–0.834; p=0.018] and MALE (HR: 0.360; 95% CI: 0.129–1.006; p=0.051) events, while the LMI group had fewer MACE (HR: 0.571; 95% CI: 0.326–1.0; p=0.050) events than the no-statin group. HI statin therapy was associated with better outcomes in terms of MALE (HR: 0.432; 95% CI: 0.223–0.837; p=0.003) than LMI statin therapy after inverse probability treatment weighting analysis. Conclusion HI and LMI statin use is associated with a significant reduction in MACE events than no-statin use. HI statin use was associated with better MALE outcomes than no-statin or LMI statin use.

Background: Although regular physical activity benefits cardiovascular health, there is a concern that intense exer‑ cise is linked to the promotion of atrial fibrillation (AF) and coronary plaque rupture. However, the impact of physical activity on the outcomes of patients with concomitant AF and coronary artery disease (CAD) remains unclear. This study aimed to evaluate the association with clinical outcomes according to the level of physical activity in patients with concomitant AF and CAD. Methods: We assessed 551 patients with AF and CAD (mean age, 67.1 ± 9.8 years) who completed a self-reported questionnaire for physical activity from 2015 to 2020 in a single tertiary-care hospital. Physical activity levels were con‑ verted into metabolic equivalent of task (MET) per week and categorized to correspond with multiple public health recommendations. We examined the association between physical activity, all-cause mortality, and major adverse cardiac and cerebrovascular events (MACCE). Results: The risks of all-cause mortality (P for linear trend = 0.017) and MACCE (P for linear trend = 0.05) appeared inverse trend with a greater level of physical activity. Compared with inactive patients, patients who met the recom‑ mended target range of physical activity (500–1,000 MET-min/week: unadjusted hazard ratio [HR] = 0.58, 95% confi‑ dence interval [CI] = 0.36–0.99) and highly active patients who exceeded the minimum recommended level (≥ 1,000 MET-min/week: unadjusted HR = 0.47, 95% CI = 0.25–0.88) had a lower risk of all-cause mortality in the unadjusted model; however, these associations did not remain significant after adjusting for the model. There was no evidence of increased risk of all-cause mortality and MACCE at levels of physical activity above the recommended target range, even with vigorous-intensity physical activity exceeding the recommended target range. Conclusions There appears to be an inverse trend between physical activity levels and all-cause mortality and MACCE in patients with concomitant AF and CAD. No excess risk of mortality or MACCE was found at exercise levels above the recommended target range. Further large-scale studies are warranted to create an improved evidence base concerning the effects of physical activity in patients with AF and CAD.
