The provision of adequate soft tissue cover for a complex hand and forearm wound-dirty, infected and exposed bone can be a challenging problem. Conventionally, a distant flap or free flap have been used, but these have been associated with several problems such as joint stiffness, risk of microsurgical procedures, negligible donor site morbidity, prolonged operation time and economic restriction. As well, fasciocutaneous flap has been the limitation of infection control. In these situations, the ipsilateral muscle flap provides the ideal cover with its rich blood supply and single operative field. Previously described by Lendrum(1980), by Lae et al.(1981), and later by McGeorge(1991), the brachioradilis muscle is the most superficial muscle on the radial side of the forearm. Its flap is based on the radial artery and venae comitantes. From August 1996 to October 1997, we performed branchioradialis muscle flap in seven patients. Despite the sacrifice of the major hand artery, brachioradialis muscle flap has many advantages including the reliability of flap survival, easy dissection, early mobilization and absence of functional and aesthetic problems at the donor site. It is a relatively simple and rapid method for resurfacing soft tissue defect in the hand and forearm. We obtained satisfactory and reliable results.

We experienced a case of primary hepatic actinomycosis which was initially diagnosed by means of fine needle aspiration. The patient was a 31-year-old emaciated man with a 2-month history of 10 kg weight loss, right upper quadrant pain and flank pain. The liver was palpable and tender on physical examination. Computerized tomography scan of the liver showed two ill-defined hypodense masses in gallbladder fossa and inferior pole of right lobe. Hepatocellular carcinoma was clinically suspected. A CT-guided fine needle aspiration was performed. Microscopically, smears showed numerous radiating clusters of filamentous bacteria with many neutrophils and monocytes in necrotic background. The symptoms were improved by incision and drainage and massive administration of penicillin.

PURPOSE: Foreign bodies in the airway of infant and children require prompt diagnosis and removal. To evaluate the pattern of clinical characteristics and disease course, we reviewed and analyzed a 6-year experience with pediatric airway foreign bodies in children. METHODS: We retrospectively reviewed the medical records of pediatric foreign body aspiration managed by pediatric and otorhinolaryngologic departments of Ajou University Hospital from November 1994 to October 2000. Nineteen cases of aspiration were collected and we analyzed their age, sex, symptoms, duration between onset of symptoms and diagnosis, initial simple radiographic findings, matierials of aspirations, anatomic location of foreign body, length of hospital day, and complications. RESULTS: The mean age was 2.7 years and male-to-female ratio of 1.8 : 1. In 11 cases, choking episode was identified by parents or patients. The correct diagnosis was made within first 24 hours of aspiration in 4 patients; while in 15 cases, the proper diagnosis was done after 24 hours. The most common presenting symptoms were cough (73.6%) and decreased breath sounds (57.9%) and the most common initial finding of simple radiographs was emphysema, presented in 68.4% of patients. Vegetable substances, particularly peanuts were the most common material of identified foreign body. Nine foreign bodies were in the right bronchus, 8 in the left bronchus and 2 in the subglottic area. The mean duration of admissions were 3.75 days in pateints who were diagnosed within 24 hours, however, 8.61 days in those with a delayed diagnosis (P=0.012). CONCLUSION: Taken together, the majority of accidental foreign body aspiration in airway was found under 3-year of age. Pediatricians and parents should be conscious to check for history of foreign body aspiration who have suspicious clinical features of aspiration, for early diagnosis and proper management without complications and long term morbidity.

In order to compare the accuracy of impression technique using the addition silicone putty and improved heavy body material, impression were taken for the natural 6 maxillary anterior teeth, and for the metal mast model that has full arch shape with 4 cylindrical abutment teeth, Marginal gingiva was retracted by routine method using retraction cord, and two techniques were tried to compare the length of impression materials in the gingival sulcus. This was aimed to see the effect of viscosity and hydraulic pressure of impression materials for the subgingival impression. Impressions for the full arch-shaped metal master model were taken to compare the linear stability of the different impression materials and their related techniques. The conclusions were as belows : 1. The one-step impression technique showed longer extension of impression material in gingival sulcus than two-step impression technique. 2. High viscosity and hydraulic pressure of impression material were useful to take subgingival impression. 3. There was no statistically significant difference for the two-dimensional accuracy of impression technique, but two-step technique showed better trend than one-step technique.

Ultrasonography, computed tomography and excretory urography in 25 patients with renal cell carcinoma were reviewed to determine their accuracy in predicting tumor stage. Staging was correct with ultrasonography in 60% of the patients, with computed tomography in 68% and with excretory urography in 40%. There was one patient, in which tumor was not identified on excretory urography. From these results, ultrasonography appears to be a good procedure as computed tomography to evaluate the stage of renal cell carcinomas.
