Anterior dislocation of lunate is rare, it can result in median nerve compression and attritional rupture of flexor tendon when delay diagnosed. We report a patient with second finger flexor tendon rupture and carpal tunnel syndrome caused by neglected anterior lunate dislocation. Patient underwent operative treatment for that excised lunate, released carpal tunnel and reconstructed second flexor tendon using palmaris longus tendon. One year after surgery, fucntional and neurologic symptom were recovered. Also carpal alignment was maintained on plain radiographs, even after excision of the lunate.

A 5-year-old boy was admitted to the hospital with a high fever and abnormal gait. Magnetic resonance imaging showed extensive swelling of the quadriceps and adductor muscles around the right hip and anterior thigh. A duplex scan demonstrated a thrombus from the external iliac vein to below the popliteal vein. The blood culture revealed Streptococcus pyogenes. The patient was immediately treated with antibiotics and anticoagulants. Follow-up sonography demonstrated complete disappearance of the venous thrombosis. We report a case of streptococcal myositis complicated by deep vein thrombosis.

Pott's paraplegia has been frequently serious complication of tuberculous spondylitis, although antituberculous drugs have improved the prognosis and healing of the disease. There are much controvercy on treatement of Pott's paraplegia, which comprises immobilization with or without anterolateral antituberculous drugs, immobilization and early posterior arthrodesis, anterolatear decompression and radical anterior decompression with anterior spinal fusion. The method of anterior decompression and anterior interbody fusion which was introduced by Hdgson since 1956 has good reults. The author analyzed 27 consecutive cases of Pott's parsplegia operated at orthopedic departement, In Je Paik Hospital from May 1980 to August 1988. The results were as follows, 1. Number of cases in child was nine(33%), both sexes were similar. 2. Regions of spine involved were most common at thoracic spine(62%). Number of affected vertebrae was averaged 3.3 vertebrae. 3. There were nineteen early(70%) and eight late(30%) paraplegia. 4. There were two complete and twenty five incomplete paraplegia. 5. In operative finding, inflammatory products and sequestrated material was extrinsic factor in early in paraplegia. 6. The recovery of the paraplegia occur in twenty cases(74%) 7. The recovery of paraplegia after treatment was far better in type of early onset, type of incomplete paraplegia less than one year duration. 8. The radical anterior decompression and anterior interbody fusion was considered as recommendable method for remove of all pathologic foci, recovery of paraplegia and healing the tuberculosis with stability.

The advent of the global pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) necessitates a thorough study of the stability and transmissibility in the environment. We characterized the stability of SARS-CoV-2 in three water matrices: fresh, tap, and seawater. The minimum infective dose of SARS-CoV-2 in Vero cells was confirmed to be 10 3 PFU/mL. The stability of SARS-CoV-2 varied according to the water matrix: infective SARSCoV-2 was undetectable after treatment with fresh water and seawater, but remained detectable for 2 days in tap water, when starting with an initial concentration of 10 4 PFU/mL. When the starting concentration was increased to 10 5 PFU/mL, a similar trend was observed. In addition, viral RNA persisted longer than infectious virus in all water matrices. This study was conducted in stagnant water containing a significantly high titer of virus, thus, human-to-human transmission of SARS-CoV-2 through the actual aquatic environment is expected to be rare.

There are few reports in the literature on how to care and manage bi!ateral congenital dislocation of the hip. Six patients have been encountered at this hospital from June 1979, of them four children had operative treat ment and the other two conservative. As a result of our experience about the management of bilateral congenital dislocation of the hip. The authors obtained the following conceptions; 1. The patient with bilateral dislocation was rather delayed in diagnosis. Therefore, in comp the treatment of bilateral cases was poorer than that of unilateral case. 2. In the case of the dislocated hip that might be easily reduced and maintained in the stab servative care was usually recommeded even in the older child. Unstable, unreduced hip,; hip in old children, the more definitive operation and internal & external rigid immobilization mandatory to get good result. 3. It might be beneficial to operate the more deformed and resistive hip first, and then to p with the same procedure 2 weeks after the first operation.

Measurement of the depth and angle of the anterior chamber can provide valuable information for the diagnosis, treatment and prognosis of angle closure glaucoma. We measured the depth and angle of the peripheral anterior chamber in the normal and the angle closure glaucoma eyes by utilizing ultrasonographic biomicroscopy. We also measured the 4 directions of the depth and angle of the peripheral anterior chamber and iris thickness before and after dilation in the normal eyes. The mean depth and angle of the peripheral anterior chamber were 421 +/- 73 micro meter, 30.46 +/- 6.49 degree in the normal eyes and 294 +/- 25 micro meter, 29.12 +/- 3.75 degree in the angle closure glaucoma eyes respectively. The differences of the depth and angle of the peripheral anterior chamber between the two groups were statistically significant(P<0.05, respectively). The depth and angle of the peripheral anterior chamber significantly increased after dilation in the normal eyes(P<0.05, respectively). The thickness of the iris was 421 +/- 54 micro meter at the iris root site, 509 +/- 57 micro meter in at the middle site and 582 +/- 74 micro meter at the pupillary margin site.

PURPOSE: The aim of this study was to compare the color stability, water sorption and cytotoxicity of thermoplastic acrylic resin for the non-metal clasp dentures to those of thermoplastic polyamide and conventional heat-polymerized denture base resins. MATERIALS AND METHODS: Three types of denture base resin, which are conventional heat-polymerized acrylic resin (Paladent 20), thermoplastic polyamide resin (Bio Tone), thermoplastic acrylic resin (Acrytone) were used as materials for this study. One hundred five specimens were fabricated. For the color stability test, specimens were immersed in the coffee and green tee for 1 and 8 weeks. Color change was measured by spectrometer. Water sorption was tested after 1 and 8 weeks immersion in the water. For the test of cytotoxicity, cell viability assay was measured and cell attachment was analyzed by FE-SEM. RESULTS: All types of denture base resin showed color changes after 1 and 8 weeks immersion. However, there was no significant difference between denture base resins. All specimens showed significant color changes in the coffee than green tee. In water sorption test, thermoplastic acrylic resin showed lower values than conventional heat-polymerized acrylic resin and thermoplastic polyamide resin. Three types of denture base showed low cytotoxicity in cell viability assay. Thermoplastic acrylic resin showed the similar cell attachment but more stable attachment than conventional heat-polymerized acrylic resin. CONCLUSION: Thermoplastic acrylic resin for the non-metal clasp denture showed acceptable color stability, water sorption and cytotoxicity. To verify the long stability in the mouth, additional in vitro studies are needed.

BACKGROUND: Although current dietary guidelines recommend to increase the consumption of whole grain, these recommendations are mainly derived from the belief that replacing fats with carbohydrate may reduce risk of coronary artery disease (CAD) by improving serum lipids. Our objective was to evaluate whether the isocalorical replacement of refined rice with whole grain reduce CAD risk factors such as insulin demand and lipid peroxidation in CAD patients. METHODS: Thirty-eight male patients with CAD were provided with 70 g powder of whole grain (220 kcal) for 16 weeks, replacing cooked refined rice as a carbohydrate source of breakfast. An oral glucose tolerance test (OGTT) was performed in all subjects to determine the effect of whole grain consumption on serum concentrations of insulin and glucose in CAD patients with different degree of glucose tolerance. RESULTS: With the substitution of whole grain for refined rice, serum glucose concentrations decreased by 24% without altering body weight and energy intake. Estimates of daily fiber and vitamin E intakes increased by 24% and 50%, respectively. Whole grain consumption in CAD patients without diabetes decreased fasting glucose (22%) and the area under the curve (AUC) for insulin (26%) and glucose (19%) during an OGTT. CAD patients with diabetes also showed reductions in fasting glucose (27%) and AUC for glucose (25%) during the OGTT, compared with baseline values. Whole grain consumption reduced plasma malondialdehyde and homocysteine and urinary 8-epi-prostaglandin F 2alpha concentrations by about 30%. Lipid-corrected concentrations of alpha-carotene, retinol, alpha- and gamma-tocopherol and lycopene increased by 22-46%, compared with baseline values. Whole grain consumption decreased the percentage composition of w6 fatty acids of serum phospholipid increased by 14%. CONCLUSION: The replacement of refined rice with whole grain as a carbohydrate source of a meal showed significant beneficial effects on glucose, insulin and homocysteine concentrations and lipid peroxidation in CAD patients. These effects are likely to substantially reduce the risk factors of CAD and diabetes in CAD patients.
