Wilson's disease is a familial disease characterized by coarsely nodular cirrhosis of the liver, sometimes associated with progressive damage to the nervous system, and the appearance of a coloured ring in the cornea. Wilson's disease is an inborn error of copper metabolism in which the synthesis of ceruloplasmin, with which copper forms a table compound in the blood, is diminished and there is an increased absorption of copper from the gastrointestinal tract together with an increased output in the urine. The Kayser-Fleischer ring is originally described by Kayser(1902) and later by Fleischer(1903). The colours of Kayser-Fleischer ring is seen, varing from rub by red to bright green or an 1lltramarine blue. sometimes interspersed with yellow or smoky shade of brown. The ring starts dose to the limbus as a sharp line just where the endothelial pattern begins to be seen distinctly, extends over a breadth of I to 3mm.. and gradually fades away towards the center of the cornea. Harry et al(1970) described that electron microscopy showed the presence of electron dense deposits of varing size lying mainly in Descmet's membrane and confirmed that the deposits were copper. A 14 year old korean boy with Wilson's disease was found to have Kayser-Fleischer ring in the cornea(ou) and greenish brown pigments on the anterior surface of the lens (ou). In about 16 months after the administration of penicillamine(chelating agent), greenish brown pigments on the anterior surface of the lens (ou) were disappeared remaining Kayser Fleischer ring unchanged.

Carcinoma of the lids has the highest incidence of any malignant ocular tumor. It is most frequent in men over 50 years of age. The majority of lid carcinoma are of the basal cell type, the remaining consist of squamous cell carcinomas and meibomian gland carcinomas. Basal cell carcinoma is much more common in the lower lid; squamous cell carcinoma in the upper lid. Squamous cell carcinoma grows slowly and painlessly, and may be present for months before it is noted. It may occlude meibomian ducts and produce an inflammatory element which may confuses the clinical picture. A 57 years old man with bronchogenic carcinoma was referred for eye consultation and found to have a small painless nodule on right upper lid that was thought to be chalazion. Palpation of preauricular, submaxillary or cervical node was negative. This small nodule was excised radically for microscopic examination to rule out a probable metastatic lesion from bronchogenic carcinma. Histopathologically, this tumor was reported not to be a secondary but to be a primary squamous cell carcinoma on right upper lid.

Extracorporeal shockwave therapy (ESWT) has been reported to be a safe and effective method for decreasing pain and relieving range of motion (ROM) limitations caused by neurogenic heterotopic ossification (NHO), though there has been no report that it might cause hematoma if applied to NHO. We hereby report a case of massive hematoma after ESWT, specifically the radial shockwave therapy (RSWT) device at both hips in a 49-year-old female patient with NHO. She had developed NHO after extensive subarachnoid hemorrhage. We had applied RSWT according to the previous report. The pain and the ROM limitations were gradually improved. Six weeks later, she reported pain and ROM limitations on the right hip. From a medial aspect, swelling and bruising of the right thigh could be seen. Magnetic resonance imaging and ultrasonography suggested a large hematoma between right hip adductor muscles. The symptoms disappeared after conservative treatment for one month, and subsequent follow-up imaging studies demonstrated resolution of the hematoma.

Background:
Single room isolation with contact precautions is widely regarded as a fundamental strategy to prevent the transmission of multidrug-resistant organisms (MDROs). However, its implementation demands substantial resources, limiting its universal application to all MDROs. In this study, we assessed the effect of discontinuing single room isolation for vancomycin-resistant Enterococcus (VRE).
Methods:
This is a retrospective, observational study conducted at a single 750-bed tertiary center. We conducted an interrupted time series analysis to compare incidence rates and trends of new-onset VRE colonization and bacteremia during the one year before and after the strategy change on January 1, 2023.
Results:
Single-room occupancy decreased from 79.7% pre-intervention to 23.6% postintervention (P < 0.001). The incidence rate of new-onset VRE colonization was 0.452 and 0.535 per 1,000 patient-days in the pre- and post-intervention periods, respectively, with no statistically significant difference (P = 0.202). However, there was a slightly increasing trend (0.036 [95% confidence interval, −0.002, 0.074] increase per month, P = 0.066). The new-onset VRE bacteremia incidence rate was not differed in incidence (0.060 and 0.055, P= 0.571) or trend (P = 0.720).
Conclusion
Our study suggests that discontinuing single-room isolation for VRE patients may not affect the incidence of new-onset VRE bacteremia, but caution is needed due to the potential increase in colonization.

Pulmonary embolism is a common clinical problem in patients with immobilization, cancer, indwelling central venous catheter and surgery. However, although rare, it may occur in patients with inherited thrombophilia. Protein S deficiency is known to increase the risk of venous thrombosis and pulmonary embolism. There are many reports of venous thrombosis with protein S deficiency, but there are few reports of arterial thrombosis, especially recurrent acute pulmonary embolism. Here, we report a case of recurrent pulmonary embolism associated with type II protein S deficiency.

Tuberculosis involving the central airway occasionally results in diffuse stenosis in the distal trachea and main bronchus. When the stenosis is more limited to the main bronchus, sleeve resection can be performed with high likelihood of a good result. Bronchial stenosis limited to 2 cm is considered favorable for bronchial sleeve resection. However, a longsegment stenosis may make sleeve resection difficult or impossible, and pneumonectomy or therapeutic bronchoscopy may be performed. An extended sleeve lobectomy is a procedure to remove more than one lobe using a bronchoplasty technique and its applications to the patients with locally advanced lung cancer were reported. We performed an extended sleeve lobectomy in a patient with tuberculous bronchial stenosis involving the right main bronchus, bronchus intermedius, right middle lobar bronchus and right lower lobar bronchus, and report this case with review of literatures.

PURPOSE: To evaluate the usefulness of locking compression plate (LCP) and volar plating through anterior approach for distal radius fracture. MATERIALS AND METHODS: We retrospectively analysed that 15 distal radius fracture, which would not be reduced by closed reduction or too comminuated to maintain reduction or articular surface inconguency, were treated by open reduction through anterior approach and volar plating using LCP. The results were evaluated by preoperative and postoperative radiographs. Functional results were analysed using the Modified Mayo Wrist Scoring System. RESULTS: All cases achieved anatomical articular surface reduction postoperatively. In terms of radiologic analysis, mean radial length (9.0 mm vs. 11.8 mm), radial inclination (14.7degrees vs. 20.9degrees ), volar tilt (-6.3degrees vs. 8.3degrees ) and articular step-off (1.4 mm vs. 0.3 mm) were improved. The average Modified Wrist Score was 89. Nonunion or malunion was not occurred. CONCLUSION: Open reduction through anterior approach and volar plating using LCP is a useful method that provides excellent results with few complications in the treatment of fracture of the distal radius.
