Minoxidil is a potent direct-acting peripheral vasodilator indicated in the management of severe or refractory hypertension. Well-known adverse effects include reflex tachycardia, fluid retention and hypertrichosis. This drug has also been reported to cause pericardial effusion in about three percent of nondialyzed patients with compromised renal function and to cause cardiac tamponade less frequently. Many studies have reported that the mean duration of therapy that caused pericardial effusion was about 8 months (range 1 month-53 months). We report a case of cardiac tamponade in nondialyzed patient with chronic renal failure receiving minoxidil for 10 years. A 58-year-old female was admitted to our hospital with dyspnea of NYHA III. She was a chronic renal failure patient without dialysis treatment and received kidney transplantation from cadaver donor and was dignosed chronic rejection in 1994. Minoxidil 10mg has been used for past 10 years. Lasix has been used for past 2 years, with dosage of 40mg to 240mg. On admission, blood pressure was 90/60mm Hg. Cardiomegaly was seen on chest radiograph. The two-dimensional echocardiogram showed a large amount of pericardial effusion. Emergency treatment with pericardiocentesis removed 2500ml of straw- colored pericardial fluid and resulted in marked improvement of dyspnea and stabilized blood pressure. The minoxidil was discontinued. The evidence of pericardial effusion was not seen for 12 months after minoxidil had been discontinued.

Spondylolisthesis and spondylolysis is one of the major causes of the low back pain and orthopaedic surgeons frequently encounter this problems with increasing tendency. In 19th century, spondylolisthesis had been studied by the European obstetrician as the main cause of dystocia. Advancement of the radiological techniques enabled us to know more precise degree of slipping. Therefore, many surgical techniques have been used. Spondylolysis has been also studied as the precursor of the spondylolisthesis. This report is based upon the analysis of the records of 26 patients who had operated at the Department of Orthopaedic Surgery of National Medical Center from 1972 to 1981. The results were as follows. 1. Most common age group was 30–50 age group and theres no sexual difference. 2. Most common symptoms were lumbago and radiating pain and the most common sign was Lasegue sign. 3. Most common type was isthmic type and location was 5th lumbar vertebra, and degree of slipping was grade I by Meyerding's method. 4. The fusion of the grafted bone were observed in 24 cases among 26 cases: of which the duration were 3 months in 16 cases and remaining 8 cases had duration between 3 and 6 months. 5. Postoperative analysis under the basis of the functional recovery was satisfactory in 93% of cases by Gill's criteria.

The present study involves 667 patients of craniocerebral injury under 15 year old who were admitted to the Department of Neurosurgery, Yonsei Medical College and Wonju Christian Hospital from January, 1982 to December, 1983. The results of which were analyzed and evaluated as follows. 1) The proportion of male to female was 2 to 1, and one third of patients was from 2 to 7 years of age. 2) The most frequent cause of injury was traffic accident : crash injury by truck and taxi and the next was fall from height and which were the causes of three quaters of all the craniocerebral injury of children. 3) Accidents were most frequent in May, and their frequent hour was from 3 P.M. to 4 P.M. 4) In 546 cases(81.9%), the consciousness was lost at the moment of the accident, and the duration was considered to be correlated with the clinical severity. Vomiting was observed in 353 cases(52.9%), and the early seizure attack accured in 31 cases(4.6%). 5) On admission, 631 patients were G.C.S. 8 and over, 25 patients were G.C.S. between 5 and 7,11 patients were G.C.S. 3 or 4. Two thirds of mortality cases were observed in G.C.S. under 7. 6) On plain skull films, skull fracture was observed in 292(43.8%) cases. Among those, depressed skull fracture was observed in 57 cases, and compound comminuted depressed fracture in 21 cases. By brain CT scan, abnormal hemorrhagic density was observed in 126 cases(18.9%), which involves 65 cases of epidural hematoma and 14 cases of subdural hematoma. In 47 cases, the hemorrhagic density was observed in intracerebral, intraventricular or intracerebellar region. 7) Associated injury accompanied by head injury was observed in 102(15.3%) cases, and mandible fracture, with or without tooth fracture, clavicle fracture, femur fracture, tibia fracture in order of frequency. It is considered that associated injury was one of the major causes of long term hospitalization and complication. 8) Total mortality rate was 3.1%, and the postoperative mortality was 6.9%.

BACKGROUND: Platelet-rich plasma (PRP) treatment is a promising tool for dermal tissue regeneration. PRP combined with subcision can synergistically induce dermal tissue regeneration. OBJECTIVE: The purpose of this study was to investigate the effects of PRP on the proliferation and migration of skin fibroblasts, as well as on the type I collagen, matrix metalloproteinase (MMP)-1, and MMP-2 expression in these skin cells. The effect of PRP with subcision on the expression of TGF-beta1 was also investigated in an animal model. METHODS: Human skin fibroblasts were treated with various concentrations of PRP. The proliferation and migration rate of the cells were evaluated by the trypan blue exclusion method and scratch assay, respectively. The expression levels of type I collagen, MMP-1, and MMP-2 were analyzed by western blot or RT-PCR. In addition, the activity levels of MMP-1 and MMP-2 were studied by zymography. Finally, we treated the animal back with PRP, subcision, or PRP with subcision. The specimens were evaluated by H&E, Masson-trichrome, and TGF-beta1 immunohistochemical staining. RESULTS: Data from this study showed that PRP more effectively promoted the migration and proliferation of cells in a dose-dependent manner. The expression levels of type I collagen, MMP-1, and MMP-2 were increased in PRP-treated fibroblasts at the protein and mRNA levels. The in vivo study revealed that the expression of TGF-beta1 was prominently increased by co-treatment with PRP and subcision rather than by treatment with either PRP or subcision alone. CONCLUSION: PRP treatment promoted fibroblast migration and proliferation, and increased the expression of type I collagen, MMP-1, MMP-2, and TGF-beta1. Therefore, PRP co-application with subcision is an effective method for dermal remodeling and can be a good treatment option for depressed acne scars.

Transient synovitis of the hip is non-specific inflammation and self limited condition, which is most common cause of painful limping in children under 10 years of age. Ultrasonography presents some merits, simple, rapid, non-invasive, low cost, repetitive to assess soft structures in and around the hip joint compared to other diagnostic methods. We prospectively studied 32 cases of unilateral transient synovitis at OPD from Jan. 1988 to Oct. 1989 using 5-7.5 MH, probe ultrasonography. 2-times serial check up in symptomatic and asymptomatic stage about capsule thickness and bone-capsule distance in 3 different positions of the both hips were performed for comparision. The following results were obtained; 1. Boys were 25 cases (78%) and 26 cases (83%) were between 3 and 7 years old of age. 2. Bone-capsule distance in ultrasonography revealed abnormal increase in 72%. 3. External rotation position showed wider bone-capsule distance than other position. 4. Capsule thickness was 3.3mm in diseased and 3.0mm in sound, 0.3mm decrease after treatment. 5. Bone-capsule distance was 4.5mm in symptomatic stage, 2.7mm in asymptomatic stage, 1.8mm decrease after treatment in averge.
