BACKGROUND: Herpes simplex virus (HSV) is associated with a insignificant skin lesion, keratitis, encephalitis, congenital infection, sexually transmitted disease, or cervix cancer. There are two types of serogroup, HSV-1 and HSV-2. HSV-1 makes the lesion mainly on the above-waist area and HSV-2 makes the lesion mainly on the below-waist area. To diagnose the HSV infection, immunological or cultural methods usually have been used until now. But they are not satisfactory in terms of sensitivity, specificity, and ease of application. Recently the polymerase chain reaction (PCR) was developed. Because of the exponential nature of the amplification, this method can detect extremely small amount of DNA. We compared nested PCR with cultural method for HSV detection. METHODS: We obtained 61 specimens from the lesions of oral mucosa, face, and genital area. Samples were inoculated into the monolayer from the African green monkey kidney cell(Vero). When the slide showed cytopathic effect(CPE), HSV infection was confirmed, After extracting DNA from 61 samples, we amplified HSV DNA using nested PCR with the primers against the gene encoding glycoprotein (gD) of HSV-1 and HSV-2. RESULTS: We found 632 bp band after the 1st PCR round and 271 bp band after the 2nd PCR round with HSV-1 specific primers. HSV-2 revealed 428 bp band after the 1st PCR round and 231 bp band after the 2nd PCR round. Nested PCR showed analytical sensitivity at 10(-9) g of DNA in HSV-1 and 10(-10) g of DNA in HSV-2. Viral culture was positive in 36%, nested PCR detected HSV DNA sequence in 54% of samples. Nested PCR typed HSV, HSV-1 in 67%, HSV-2 in 39%, and mixed type in 6% of PCR-positive samples. All isolates from above-waist area were HSV-1. Seventy seven percent of 13 isolates from below-waist area were HSV-2 and 38% were HSV-1. CONCLUSIONS: Nested PCR offers a rapid, simple, and sensitive test for HSV infections of skin and mucosa.

By means of hospital-based data over 8 years we sought to evaluate the clinical indications and incidence of emergency peripartum hysterectomy by demographic characteristic and reproduction history. From the obstetric record of all deliveries at Chung Goo Hospital between Jan. 1, 1990, and Nov. 31, 1997, we identified all women undergoing emergency cesarean hysterectomy, calculated incidence rates, conducted statistical tests of linear trends and heterogenety, and observed the clinical indicatons preceding the onset of this procedure. There were 16731 deliveries during this period, Cesarean hysterectomy was performed in 24 of 5993 cesarean sections(0.40%) and in 10 of 10738 vaginal deleveries(0.09%), so more frequently after cesarean section than vaginal delivery. The age of patients varied from 22 to 40 years old. The higher the age and the parity of patients, the higher incidence of cesarean hysterectomy was noted. The most common indication of cesarean hysterectomy was uterine atony(52.94%) followed by placental disorders(41.18%), uterine myoma with pregnancy(2.9%) and uterine rupture (2.9%). All patients who had hysterectomy received transfusion from 1 pint to 57 pints. The postoperative complications were bladder injury, febrile morbidity, disseminated intravascular coaguolopathy and wound disruption. There were three maternal deaths, the cause was disseminated intravascular coaguolopathy and amniotic embolism. The data identifiy uterine atony as the primary cause for gravid hysterctomy. The data also illustrated how the incidence of emergency peripartum hysterectomy increases significantly with increasing parity, especially when influenced by a current placenta previa or a prior cesarean section. Maternal morbidity remained high.

BACKGROUND: The goal of this study was to evaluate whether a modified fluoroscopic technique for positioning a hook plate affected the clinical results of treating Neer type II distal clavicle fractures and Rockwood type V acromioclavicular (AC) joint separations with this device. METHODS: The study was a retrospective consecutive case series with data analysis. Sixty-four patients with a Neer type II distal clavicle fracture or a Rockwood type V AC joint injury treated between March 2009 and June 2013 were divided into 2 groups: traditional fluoroscopic technique (traditional view, 31 patients) or modified fluoroscopic technique ('hook' view, 33 patients). A visual analogue scale (VAS) score, the modified University of California-Los Angeles (UCLA) shoulder scale score, and radiographic osteolysis were the main outcome measures. RESULTS: The traditional group included a significantly larger number of patients with acromial osteolysis than the hook view group: 23 patients (74.2%) vs. 11 patients (33.3%), respectively (p=0.01). Before plate removal, the hook group reported less pain and higher UCLA shoulder scale scores than the traditional group: average VAS score, 1.55 vs. 2.26, respectively; average UCLA score, 30.88 vs. 27.06, respectively. However, there was no significant difference after plate removal. CONCLUSIONS: The hook view allows more accurate bending of the hook plate around the contour of the acromion, resulting in decreased osteolysis, decreased pain, and better function with the plate in situ.

To differentiate the postoperative changes from the recurrence of tumor and to evaluate MR imaging of early postoperative leptomeningeal seeding in medulloblastoma, We have retrospectively analysed 34 cases of MR images of 17 patients who were confirmed as medulloblastoma by histopathology. Noncontrast and postcontrast T1 weighted MR images were obtained in all patients. In 11 patients follow-up MR was done more than once (average:1.5 times) and average interval of MR imaging was 6 months. The timing of 34 MR images was as follow: 6 case within 2 months, 9 cases between 2 months and 1 year, 19 cases more than 1 year after surgery respectively. MR images within 2 month after surgery revealed contrast enhancement at operation site and adjacent meninges, hemorrhage, residual tumor. In patients who had no evidence of tumor recurrence, these early postoperative changes were markedly decreased within 6 month after sugery. MR images obtained more than 1 year after sugery showed no abnormal contrast enhancement or mild focal dural enhancement at operation site. Diffuse moderate dural enhancement was noted in one patient who had the history of post-surgical subdural hemorrhage. In six patients with tumor recurrences which were detected from as early as 9months to 6 years after surgery, the findings of recurrence included leptomeningeal enhancement of brain stem and cerebellar surface at early stage, variable sized enhancing leptomeningeal nodules, linear or irregular sulcus obliterating enhancing lesions, enhancing mass at primary or metastatic site. We have concluded that leptomeningeal enhancement detected after 6 months of surgery is an important MR finding suggesting the possibility of tumor recurrence. Small nodular and linear enhancement of leptomeninges at brainstem or cerebellar surface is considered as the early manifestation of intracranial tumor seeding.

McCune-Albright syndrome, which consists of cafe-au lait spots, multiple fibrous dysplasia, sexual precocity and endocrinal dysfunction such as pituitary, thyroid and adrenal aberrations, has been increasingly recognized recently. The etiology is now suggested that activating mutations on the gene that encodes the alpha subunit of stimulatory G protein cause McCune-Albright syndrome. The child presented with sexual precocity and elevated estrogen level was still persisted after left oophorectomy and right partial oophorectomy due to misdiagnosed as ovarian granulosa-theca cell tumor. Whole body bone scan revealed abnormal radiotracer uptake on left facial bone and left proximal femur. Facial bone MRI showed marked thickening of facial bone from fibrous dysplasia. And the patient had cafe-au-lait pigmentations on neck and buttock area. Other endocrine function was normal. Pathologic finding of ovary was finally confirmed with cystic follicles. Skull biopsy revealed fibrous dysplasia. And she was finally diagnosed McCune-Albright syndrome.

Hypergammaglobulinemic purpura of Waldenstrom is a distinct syndrome consisting of recurrent episodes of purpura, elevated serum r-globulins, elevated erythrocyteed rnentation rate, and mild anemia. This disease has been divided into the prirnary type without an uncerlying disease, and the secondary type with a known underlying disease. We diagnosed a hypergammaglobulinemic purpura of Waldenstram in a 53-year-old woman who presented sudden onset of showers of purpuric macules and petechiae of 24 hours duration involving her lower extremities with a 10-rnonth history. She showed characteristic laboratory findings consistent with those of hypergammiglobulnemic purpura of Waldenstrorri and also showed positive results of antinuclear antibody and rheumatoid factor. We tried to find out if there we any associated underlying disases such as systemic lupus erythematosus or Sjogren synirorne through various tests but faile it find any. We concluded she showed a primary type of hypergarnmhglobulinemic purpura of Waldcnstrorn.
