While the microbiology of cellulitis in the pediatric population and systemic diseases(DM, Cirrhosis, etc) is well known,the causative bacteria and clinical aspect of cellulitis in young adults are less descrihed. this study was undertaken to identify the causative organisms and clinical aspect of adult cellulits. We analysed 121 medical records of 115 young adult patients with cellulitis who had been admitted at the department of orthopaedic surgery, National Police hospital from Jan. 1994. to Dec. 1996. The results were as follows. 1. The age of patient was between 21 yrs and 25 yrs, and the sex of all patients was male. 2. The lower leg and foot were the most frequently involved site of cellulitis as 92 cases(74.2%). 3. The potals were suspected in 65 cases(56.5%),of them, traumas were detected in 43 cases(66.1%), non-traumatic skin lesions in 23 cases(33.9%). 4. In most cases, initial systemic symptoms (fever, chill, headache, etc.) and local symptoms (local heating, tenderness, etc.) were found. 5. The laboratory findings revealed leukocytosis in 19%, elevated ESR in 94%, positive CRP in 80%. 6. Microorganism were detected in 16 of 38 pus cultures. Gram positive microorganisms were detected in 15 of 16 cases culture positive. 7. 6.7% of patients with cellulitis experienced recurrence in same lesions. In conclusion, the retrospective analysis of 115 young adult patients with cellulitis showed that primary cause of young adult cellulit was circulatory disturbance and lymphatic obstruction of the lower extremities most often involved by trauma. therefore, supportive treatments such as rest,elevation,ice packs are considered prior to antibiotic treatment.antibiotic treatment aimed at gram-positive cocci appears to be sufficient.

Forty five cases of adult tibial shaft fractures were treated with flexible intramedullary nails under image intensifier at the department of orthopaedic surgery, Capital Armed Forces General Hospital during between April 1986 to July 1988. The results were summarized as follows: 1. 45 cases were all male, the average age was 24.3 years and the most common cause of fractures was sports injury(20 cases) and the second most common cause was traffic accident(18 cases). 2. 11 cases out of 45 cases were open fracture and 34 cases were closed fracture. Eight cases of open fraeture were grade I and three cases were grade II. Twenty eight cases were comminuted fracture. The most common level of the fracture was middle third of the tibial shaft. 3. Average interval from injury to Ender nailing was 13.5 days and the mean duration of permission to full weight bearing was 9.2 weeks. 4. Out of 2 cases of delayed union, the average time of clinical bone union was 9.7 weeks and that of roentgenological bone union was 14 weeks. 5. 11 cases of complication were noted among the 45 cases of tibial shaft fracture which were treated by PGP nailing such as angulation, rotation, ankle joint stiffness, delayed union, shortening, and soft tissue infection. 6. PGP nailing is considered to be a valuable method in treating tibial shaft fracture because of their relative ease of nailing, allowing early weight bearing and decreased complication.

Nitric oxide (NO) is a small molecule (mol. wt. 30 Da) and oxidative free radical. It is uncharged and can therefore diffuse freely within and between cells across membrane. Such characteristics make it a biologically important messenger in physiologic processes such as neurotransmission and the control of vascular tone. NO is also highly toxic and is known to acts as a mediator of cytotoxicity during host defense. NO is synthesized by nitric oxide synthase (NOS) through L-arginine/nitric oxide pathway which is a dioxygenation process. NO synthesis involves several participants, three co-substrates, five electrons, five co-factors and two prosthetic groups. Under normal condition, low levels of NO are synthesized by type I and III NOS for a short period of time and mediates many physiologic processes. Under condition of oxidant stress, high levels of NO are synthesized by type II NOS and inhibits a variety of metabolic processes and can also cause direct damage to DNA. Such interaction result in cytostasis, energy depletion and ultimately cell death. NO has the potential to interact with a variety of intercellular targets producing diverse array of metabolic effects. It is known that NO is involved in hemodynamic regulation, neurogenic inflammation, re-innervation, management of dentin hypersensitivity on teeth. Under basal condition of pulpal blood flow, NO provides constant vasodilator tone acting against sympathetic vasoconstriction. Substance P, a well known vasodilator, was reported to be mediated partly by NO, while calcitonin-gene related peptide has provided no evidence of its relation with NO. This review describes the roles of NO in dental pulp in addition to the known general roles of it.

To clarify the mechanism of the protective effect of hemodialysis on lipid peroxidation in RBC membrane structures, the level of malondialdehyde (MDA) which is the lipid peroxidation product, and the activities of antioxidant enzymes such as superoxide dismutase (SOD), catalase, and glutathione peroxidase (GSH-Px) were determined before and after hemodialysis in the RBCs from 20 patients with end stage renal disease (ESRD), and from 14 healthy subjects. Before dialysis, MDA levels in the RBCs from the patients with ESRD were higher than those from healthy controls. SOD and catalase activities in the RBCs were lower. After hemodialysis, MDA, SOD, and catalase in the RBCs from the patients with ESRD were normalized. These results indicate that hemodialysis treatment is helpful to protect the peroxidative darnage through normalizing the activities of antioxidant enzymes.

The authors analyzed retrospectively the 36 patients with malignant salivary gland tumors who were treated at Department of Oral and Maxillofacial Surgery, Pusan National University Hospital from February, 1989 to September, 1997. The results obtained were as follows: 1. There were 14 males( 38.9%) and 22 females(61.1%). The peak age of patients with major salivary gland tumors was the 6th decade, but with minor salivary gland was the 5th decade. 2. Of all salivary gland tumors, 5 cases arose in the parotid glands, 2 cases in the submanibular glands, 1 case in the sublingual gland and 28 cases in the minor salivary glands. 3. The incidence according to the anatomic primary site for minor salivary glands was 15 cases in the palate, 5 in the floor of mouth and 2 cases each arising in the tongue, lip, retromolar area and buccal mucosa. 4. Of all salivary gland tumors, adenoid cystic carcinoma was 5 cases in the major salivary glands and 8 in the minor salivary glands. mucoepidermoid carcinoma was 2 cases in the major salivary glands and 14 in the minor salivary glands and others were 2 cases of adenocarcinoma, 4 malignant mixed tumors and 1 undifferentiated carcinoma. 5. The incidence of cervical lymph node metastasis was 100%(2/2) in the submandibular glands, 80%(4/5) in the floor of mouth, 50%(1/2) in the tongue and 20%(1/5) in the parotid glands. The highest incidence of lymph node metastasis according to histopathological classfication was found in the high grade of mucoepidermoid carcinoma and tubular type of adenoid cystic carcinoma. 6. Nerve invasion was common in the adenoid cystic carcinoma. 7. The lung was the commonest site for distant metastasis comprising 7 cases among 7 cases in which distant spread occurred.

PURPOSE: To compare the outer retinal thickness in normal fellow eyes of patients with unilateral age-related macular degeneration (AMD) and normal control eyes. METHODS: We retrospectively reviewed the medical records of 60 patients with unilateral exudative AMD including polypoidal choroidal vasculopathy and 60 normal controls. Spectralis optical coherence tomography was performed in the normal fellow eyes of patients with unilateral AMD and in the normal group. The thicknesses between the retinal pigment epithelium (RPE) line and the cone outer segment tips (COST) line, between the COST line and the photoreceptor inner segment/outer segment (IS/OS) line, and between the IS/OS line and the external limiting membrane (ELM) line were measured at the fovea in both groups. RESULTS: The thickness between the RPE and COST lines was 32.4 ± 3.0 µm in normal fellow eyes of patients with unilateral AMD and 35.3 ± 3.5 µm in the normal group (p < 0.001). Total retinal thickness, thicknesses between the COST and the IS/OS lines and the IS/OS and the ELM lines in fellow eyes were not significantly different from those of normal eyes (p = 0.126, 0.615, 0.874). There was no significant difference in total retinal thickness or each outer retinal thickness measured in normal fellow eyes between patients with neovascular AMD and polypoidal choroidal vasculopathy. CONCLUSIONS: The thickness between the RPE and the COST lines was thinner in the fellow eyes of patients with unilateral AMD than in the normal eyes. We suggest that less thickness between the RPE and COST lines might indicate a greater risk of AMD.

To identify clinical significance of prostate specific antigen (PSA) in orchiectomized patients with metastatic prostate cancer, we longitudinally investigated significant factors in the progression of the advanced prostate cancer in 28 patients who were comparatively well followed after subcapsular orchiectomy. Following results were obtained. 1) The mean followup interval was 25.9 months (1 to 68 months). Mean patient age was 67.6 years (50 to 82 years). 2) Eleven of 28 patients were expired during follow-up. Death rate was 39.3 percent. 3) Patients whose post-treatment nadir PSA level decreased below 2.8 ng/ml had a significantly longer remission duration rate than those whose nadir PSA remained elevated (mean survival times 53.9 versus 25.4 months, survival rate 85.0 versus 0%, p <0.01). 4) Patients whose interval to nadir PSA was less than 6 months had a significantly longer remission and a larger survival rate than those whose interval to nadir PSA was more than 6 months (mean survival times 58.3 versus 36.4 months, survival rate 93.3 versus 33.3%, p <0.05). 5) After orchiectomy, patients whose duration from nadir PSA level decreased below 2.8 ng/ml to the above 2.8 ng/ml was more than 9 months had a significantly longer remission duration and a larger survival rate than those whose duration was less than 9 months (mean survival times 62.7 versus 24.9 months, survival rate 88.9 versus 27.3%, p <0.001). 6) Patients whose serum PSA was changed earlier than bone scan had a significantly shorter survival duration and a smaller survival rate than those whose bone scan was changed earlier than PSA (mean survival times 24.4 versus 50.3 months, survival rate 30.0 versus 75.0%, p <0.05). 7) Patients whose Gleason grade was below 3 had a better prognosis than those whose Gleason grade was above 4 (mean survival times 50.4 versus 29.9 months, survival rate 78.6 versus 42.9%, p<0.05). 8) Patients` age over 70 years at the time of diagnosis was a Significantly better prognostic factor (p<0.05). pre-treatment PSA levels and PSA half-times were not significant in advanced prostate cancer patients (p>0.05). As the result of the above, we conclude that serial serum PSA levels in advanced prostate cancer patients after endocrinal therapy can aid in distinguishing favorable from nonfavorable responders early in the course of therapy and greatly assist in monitoring for progression.
