Nine scaphoid non-unions, which were treated by through curettage of the scar tissue on pseudarthrosis, iliac bone grafts between the fragments and Herbert screws fixation, were analysed. The average follow up period from operation was 16.9 months. The interval between the fracture and the time of the operation ranged from 10 months to 48 months(average 21.6 months). Average union time was 14 weeks after operation. The initial radiologic cystic changes disappeared and overall clinical results were improved. Mean postoperative range of motion of the wrist was flexion 55 and extension 45°. Three of them had DISI deformity preoperatively which their scapholunate angles (mean 104°) has been corrected after reduction (mean 75°). In one case among three DISI deformities, partial radial styloidectomy and triscaphe fusion were added (to bone graft and Herbert screw fixation). A case of incorrect positioning of the screw and a case of neuroma were complicated. Treatment of scaphoid nonunion with curettage of the scar tissue and iliac bone graft and Herbert screw fixation seems to be encouraging to regain the normal anatomy of scaphoid and function of the wrist.

PURPOSE: Because cryptorchid testes are known to undergo histopathologic changes affecting development, maturation, and tertility, early surgical correction is usually recommended. However there are differing opinions concerning whether retractile testes are affected by similar changes and also whether there is a need for surgical treatment. We aimed to assess the histopathologic changes in retractile testis by studying the changes in testes artificially placed back in the abdomen after they have descended to scrotum in experimental rat models. MATERIALS AND METHODS: Male Sprague-Dawley rats were divided into 3 groups; a control group(controls), prepubertal ascent group (P) in which testis were placed back intraabdominally by bilateral inguinal canal obstruction at 6 weeks, a neonatal group(N) in which intraabdminal testis was induced by bilateral inguinal canal obstruction at birth. The relative weight of the testis, morphology of the seminiferous tubules including Leydig cells, tubular degeneration phase(TDP), spermatogonia per tubules(S/T), and Sertoli cell index (SCI) of these three groups were analyzed and compared. RESULTS: The relative weight of testis was significantly decreased in the group of N(0.0016+/-0.001) and P(0.0015+/-0.0002) compared to controls(0.0037+/-0.0002) (p<0.05). The S/T value was also decreased in P(2.05+/-18.2) and N(73.2+/-32.4) when compared to controls (360.2+/-21.3). Similar changes were observed in SCI of both P(64.5+/-6.4) and N (91.2+/-14.2) when compared to controls (227.9+/-31.1). Only minority of N and P showed higher TDP values. However, although statistically insignificant, TDP was increased in both P and N when compared to controls. The Leydig cells in N and P showed cellular distortion and hypertrophy. CONCLUSIONS: This study demonstrate that prepubertal ascent, similar to that of innate cryptorchid testis, also can induce histopathologic changes such as changes in testicular seminiferous tubule, decrease in the S/T value and decrease in SCI value. Our findings supports that hypothesis that retractile testis may cause histological damage thus surgical correction may also be warranted similar to in case of genuine cryptorchism.

The authors investigated the radioallergosorbent test (RAST) for the specific IgE and the prick test with hose dust mite in 129 patients with atopic dermatitis(AD) wit4 four or more family numbers. RAST and prick test results were described according to family background of respiratory atopy(RA) and severity of AD. The results are summarized as follows : l. A comparison between the prick test results and RAST reactions gave a concordance of 88%. The prick test was more sensitive than the RAST. 2. The level of specific IgE in patients with personal history(PH) or family history(FH) of RA was significantly increased compared to those in patients with only AD. 3. In patients without PH and FH of RA, the level of specific IgE in patients with FH of AD was significantly increased compared to those in patients without FH of AD. 4. The level of specific IgE did not reflect the severity of AD. From the above results, it could be concluded that type I allergy to house dust mite is not directly related to AD and it occurs predominantly in those patients with AD wha have a predisposition to RA.

Sjogren's syndrome has been considered to be an autoimmune disease affecting various organs including salivary and lacrimal glands. It occurs most commonly in middle-aged women, and less than 20 cases with primary Sjogren's syndrome have been reported in children. An 11-yim-old boy presented with recurrent annular erythema on the face that had been present for 2 years. A schirmers test showed a positive result. ANA was detected at a dilution of 1:640. Anti-Ro/SSA and anti-La/SSB antibodies were also detected. On histological examination, lymphocytes were infiltrated in the periappendegeal areas as well as the papillary and reticular dernis. The skin findimg is uncommon in children, but has become a characteristic feature of childhood Sjogrens syndrome with anti-Ro and/or anti-La antibodies.

OBJECTIVE: We analyzed the clinical features of amniotic fluid embolism confirmed by autopsy or clinical dicision for making a plan of rapid diagnosis and intensive emergency care. STUDY DESIGN: We experienced 2 clincal cases in Ewha Mokdong Hospital and Severance Hospital at 1995, and reviewed the medical record & autopsy report of 15 cases in National Institute of Scientific Investigation from Jan, 1991 to Dec, 1995. RESULTS: The mean maternal age was 31+/-3 years. The mean gestational age was 40+/-1 weeks. The number of delivery were 1.4+/-0.8. The number of abortion history. were 2.6+/-2. The sexuality of fetus were six males (35 %), five females (29%), and unknown six cases (35 %) and the fetal mortality rate was 29 % (5 cases). The initial clinical symptoms and signs were hypotension (12 patients, 71%), vaginal bleeding(ll patients, 65%), cardiac arrest (6 patients, 35 %), dyspnea (5 patients, 29 %), and seizure (2 patients, 12%). In the case of normal spontaneous vaginal delivary (NSVD), the symptoms occurred during induction in 3 (18%), during delivery in 1 (6%), and after delivery in 9 (53%). In the case of Cesarean section, the symptoms occurred during section in 2 (12%), and after section in 1 (6%). There are one case whose symptoms occurred during 3rd gestational period. CONCLUSIONS: We should alert for the amniotic fluid embolism in the clinical findings of acute collapse and vaginal bleeding, respiratory symptoms, and seizure at any peripartum. With eary suspicion of this disease and aggressive intensive care we can reduce amniotic fluid embolism mortality rate and it's legal problem.

This retrospective study comprised patiens with facial bone fractures in various accidents and treated in the department of Plastic and Reconstructive Surgery, Pildong hospital, Chung Ang university during the past 5 years from January 1994 to December 1998. The medical records of these patients (fractures) were reviewed and analysed in order to gain insight into a clinical pattern and understnad the therapeutic modalities. The following results were obtained: 1. The monthly incidence was highest in August and most common accident time was between 6:00 p.m and midnight. 2. The mean age of patients was 28.3 years, and age range was 3 to 69 years. The most prevalent age group was the third decade of life (42.9%). Males predominated more than female in the ratio of 4.1:1. 3. The most common etiology was assault (29.6%) followed by traffic accidents (28.5%), fall (23.1%), sports (7.9%). 4. 369 facial fractures in 277 patients were classifed. The most common sites were nasal bone, followed by zygoma, mandible, maxilla, orbit. 5. Associated soft tissue injuries were combined in 168 patients (60.6%), and fractures other than facial bone were developed in 61 patients (22%). 6. Treatment of facial bone fracture consisted of open reduction (42.6%), closed reduction (40.1%), and conservative treatment (17.3%). 7. The complication rate was 11.6% and the most common complication was the eye problem.

Wiskott-Aldrich syndrome is an X-linked combined immunodeficiency disorder characterized by severely decreased number of platelets which are small in size, eczema resembling atopic dermatitis and recurrent infection. The serum of the patient contains elevated concentrations of IgA and IgE, whereas the IgG level is usually normal and IgM level is decreased. The patients also shows skin test anergy and progressive T-lymphocytopenia. Bleedings and recurrent infections are the main causes of death and the patients usually die before age 10. Bone marrow transplantation is accepted to be the only radical therapy. We experienced a case compatible with Wiskott-Aldrich syndrome in a 5 year old male child who accompanied above clinical manifestations and laboratory findings.

Streptococcus anginosus is a member of Streptococcus milleri group, and is found in the oral mucosa, respiratory tract, and gastrointestinal tract as normal flora. It can develop into a disease in patients with deteriorating clinical condition or with clinical risk factors. A previously healthy 15-year-old boy was admitted due to fever, abdominal discomfort and vomiting which lasted for 7 days. He had a history of dental procedure 1 day before the development of fever. He was diagnosed with acute acalculous cholecystitis based on the clinical, laboratory, and imaging finding, and S. anginosus was isolated from the blood culture. The patient was successfully treated with antibiotic therapy.

Advances in multimodal treatment using radiation and chemotherapy, more sophicated diagnostic, radiologic methods, and newer reconstructive surgical techniques have led to aggressive surgical treatment of chondrosarcoma of the pelvis. Recently, good results have been reported in even high grade chondrosarcoma of the pelvis with surgery with/without adjuvant therapy. From January 1984 to June 1992, ten patients with chondrosarcoma of the pelvis were treated. Their average age was 40(18 to 55). Location of the lesion were ilium(5), periacetabular lesion(1), ischiopubic region(1) and sacrum(3). Nine cases were conventional type and one was dedifferentiated type. Surgical resection was done for nine patients, with which radical margin in one, wide margin in four, marginal margin in one and intralesional margin in three. Postoperative radiotherapy(6000-7000cGy during 6-7week) was done for five patients of having wide(1), marginal(1) or intralesional(3) surgical margin. One patient took radiotherapy only after biopsy. The average follow-up period was 2 years and 9 months(1 year to 6 years 1 month). Six patients wer continuously disease free(CDF) or disease free(DF). One patient is alive with disease(AWD). Three patients died of disease(DOD). With Kaplan-Meier's method, 5-year actuarial survival rate for total 10 cases was 60%, for operated group(9 cases) 66.7% and for operated conventional group(8 cases) 80%. With wider resection margin, better survival could be achieved.

Staphylococcus species are one of prevalent pathogens found in hospitals. Microbes that are a primary cause of nosocomial infection were isolated from a dental and medical environment it may assist the reader to explain what this is and how it differs from the 'dental health care providers and ward health care providers'. To investigate the distribution of staphylococcus species in this environment, we used vitek II to measure drug sensitivity, and further performed biochemical testing. The isolation rate of staphylococcus species from the dental and medical environment was 100% but from dental health care providers and ward health care providers were 44.4% and 33.3%, respectively. In the analyses, staphylococcus species showed resistance to diffusion of cefoxitin and oxacillin discs. These staphylococci may be sufficiently positive for the mecA gene. Our results suggest that staphylococci might be an important cause of nosocomial infection in the dental clinic.
