1.Identification of Human Papillomavirus(HPV) in Patients with Cervical Cancer by DNA Hybridization.
Korean Journal of Gynecologic Oncology and Colposcopy 1990;1(1):72-79
Genomic DNAs were extracted from cervical lavages of 49 patients with cervical cancer. Dot and Southern blot hybridization were performed using the P-labeled HFV DNA probes to find high risk HPV(type 16 and 18) infection that is known as the mast prevalent pathogenic factor in cervical cancer. Furthermore, genornic DNAs purified frnm cervical cancer tissues were studied in 8 out of 49 patients allowing us to convince the results from cervical lavages. The results were as follaws: 1. Dot blot analysis were used to examine the sensitivity and specificity of hybridization condition and HPV-DNA probes. Fasitive signals were obtained even at the level of 10pg for HPV DNA, but no signals could he detected at the level of as much as 400pg for salmon sperm DNA. 2. Dot blot of DNAs from cervircal lavages showed positive signals in 32.7%(16/49) with HPV type 16 probe and 20.4% (10/49)and one mixed infection was found. 3. When the DNAs from cervircal lavages of 49 patients were classified according to the clinical stage of cervical cancer, the infection rates of HPV type 16 and 18 were 50% (2/4) in CIN, 80% (4/5) in stage I, 64. 2% (9/14) in stage I b, 45% (9I20) in stage II and 16. 7% (1/6) in stage Ill and K respectively. The occurrenr,e of HPV type 16 and 18 seemed to be the highest in the cervical cancer stage 1 (68.4%(13/19). 4. Experiments perfornecl with genomic DNAs from 8 cancer tissues showed similar results compared to those of cervical lavages, but the intensity of positive signals was stronger. 5. Genomic DNAs from 5 patients(3 cases from cervical lavages and 2 cases from cervical cancer tissues) which showed strong positive signals to the dot blot analysis were further examined by Southern blot hybridixation using HFV type 16 DNA probe. When DNAs were digested with Pst 1 restriction enzyme, the five characteristic frgmenta of BFV type 16(2.8, l.9, l.6, 1.0 and 0.5 kb long in length) were recognized in ell 5 cases, These results may suggest a direet relatianship between HPV type 16 & 18 infectioas considered as the most effective methods for HPV detectioe and typing. Mo1ecular biclogieal studies in the reserarch of HPV are expected to reveal and help us understand the pathogenesis of cervical cancer.

We report a case of 17-year-old female with juvenile onset systemic lupus erythematosus Who developed symptomatic unilateral sacroiliitis. She had neither HLA-DR3 nir B27 antigens. Though sacroiliitis have been reported in mail SLE patient. it has been rarely reported in female patients. The rare coexistence of SLE and sacroiliitis. described in this case. may not be determined soley by genetic factors; sacroiliitis may be just an infrequent manifestation of SLE.

OBJECTIVES: Anticardiolipin antibody (ACA) and lupus anticoagulant (LA) are acquired antiphospholipid antibodies (APAs), which are regarded as important risk factors far vascular thrombosis and recurrent fetal loss. Although the clinical relevance of APAs in dialysis patients is uncertain, recent studies have suggested that APAs are involved in bioincompatibility and thrombogenic complications in hemadialysis (HD) patients. METHOD: We performed a cross sectional study of ACA and LA in 50 stable HD patients and their 68 vascular accesses (52 native arteriovenous fistulae and 16 synthetic arterovenous grafts), with the analysis of factors associated with the presence of APAs and the retrospective evaluation of vascular access occlusion (VAO). LA was assessed by platelet neutralization method whereas IgG-ACA was measured by a solid phase ELISA. Values higher than 23GPLU/ml (IgG phospholipid units) were considered to be positive for IgG-ACA and positive values for LA was more than 8 seconds in prolongation of the clotting time with human platelet lysate. Vascular access survival was assessed by Kaplan- Meier method, RESULTS: The mean age of the subject (M:F 21:29) was 46 years and the mean duration of hemodialysis was 49 months. The frequency of VAO in entire subjects was 0.45+/-0.98 episodes/patient year. The median value of IgG-ACA was 16.0 GPLU/ml with a distribution from 2.7 to 46.1GPLU/ ml. The median titer of I.A was 4.5 (3.1-45.6) seconds. Fourteen patients (28%) were found to have at least one episode of VAO. In spite of comparable clinical and biochemical data according to the presence of VAO, the titers of IgG-ACA (13.6+/-7.7 vs, 20.3+/-8.7GPLIJ/ml, P<0.05) and LA (4.5+/-2.9 vs. 11.7 +/-12.6sec, P<0.05) were significantly higher in VAO group. Six out of 50 patients(12%) had an increased titer of IgG-ACA and LA was found in 11 patients(22%). No patients were positive for ACA and LA simultaneously. There was no significant difference in sex, etiology of ESRD, diabetic status, the dosage of heparin during HD or the amount of erythropoietin administered according to the presence of APAs. We could not find any significant correlation between the titer of APAs and age, duration of dialysis, blood pressure, platelet count and biochemical parameters. In the patients with positive ACA, the frequency of VAO was 1.05+/-0.12 episodes/patient year, which was significantly higher than patients without ACA (0.33+/-0.17 episodes/ patient year, P<0.05). In the patients with the presence of LA(1.06+/-0.43 vs. 0.12+/-0.06 episodes/ patients year, P<0.01). The median vascular access survival time in IgG-ACA positive patients (32.7 months) was significantly decreased compared to 66.8 months in IgG-ACA negative group. CONCLUSION: Our data suggest that the presence of APAs (ACA and/or LA) affects the event-free vascular access survival in HD patients. Therefore the evaluation of APAs status have to be included in the diagnostic strategies for the patients with recurrent VAO. Further studies are necessary to explore the pharmacologic intervention method to decrease APAs and prevent VAO in HD patients.

We present an unusual case of 31 year old lady with a longitudinal tear of flexor hallucis longus(FHL) caused by trauma. Tendonitis of the FHL, well known as dancers tendonitis, can be characterized by triggering of the great toe. As the foot is brought into plantar flexion with a forcible active contraction of the FHL, a snap is noted in the region of the posteromedial aspect of the ankle. Magnetic resonance imaging may be helpful in establishing diagnosis. The patient has obtained longterm satisfactory relief of her symptoms with surgical treatment. The literature on tendonitis of the FHL is reviewed with a reported case.

Traumatic hemoperitoneum can still induce high mortality and morbidity rates, despite current method of intensive management. This study was performed to identify the independent prognostic factors in patients with traumatic hemoperitoneum. Two hundred thirty-six patients who underwent emergency operations because of traumatic hemoperitoneum at the Department of Surgery, Dong Kang General Hospital, Ulsan, from January 1986 to June 1994, were entered into this retrospective study. One hundred eighty-six patients were male, and fifty were female. The median age of the patients was 34 years (2 to 77 years). The modes of trauma were 131 motor-vehicle accidents, 43 fall down injuries, 30 stab injuries, 23 assaults, and 9 others . The common sites of injury were lthe iver and the spleen, followed by the mesentery, the stomach, the small bowels, the large bowels, the pancreas, the kidney, the diaphragm, and the retroperitoneum in order of frequency. Prognostic variables were identified from the perioperative parameters by using a univariate analysis(student t- test, chi-square test), and independent prognostic factors were determined by a multivariate stepwise logistic regression analysis, using the SPSS Win. Ver.5.0 PC package program. Statistical significance was present for p < 0.05. The overall postoperative morbidity and mortality rates were 34.3% and 19%, respectively. By using univariate analysis, the amount of bleeding, transfusion, and the immediate post-operative blood pressure were identified as significant prognostic factors for morbidity. Also age over 50, accompanying brain injury, time interval (less than 3 hrs), the systolic blood pressure on arrival (less than 100 mmHg), trauma score (less than 10), grade of liver injury (greater than IV), great vascular injury, total amount of resuscitative fluid (more than 4,000cc), the total amount of transfusion (more than 10 units), and the immediate postoperative systolic blood pressure (less than 100 mmHg) were identified as significant factors for mortality. Multivariate analysis demonstrated the following important independent prognostic factors : the total amount of transfusion for morbidity and mortality, and the post-operative blood pressure and trauma score for mortality. Our results suggest that early massive resuscitation, early operation to minimize the total amount of blood loss, and intensive immediate postoperative care to maintain blood pressure, are of utmost importance in multiple trauma patients with hemoperitoneum.

BACKGROUND: Lipoprotein(a)[Lp(a)] is a subspecies of low-density lipoprotein and has been shown to be associated with pathogenesis of thrombosis-related disease. It is already known that patients with diabetic nephropathy are usually complicated by vascular complications such as coronary artery diseases and cerebrovascular accidents. According to the recent data, Lp(a) level tends to be increased as the proteinuria is increased and renal function are decreased. We evaluated the Lp(a) level to know whether its level is correlated to the severity of diabetic nephropathy. METHODS: We investigated Lp(a) levels in eighty-one patients with Type 2 (non-insulin-dependent) diabetic patients. They were divided into four groups according to the level of urinary albumin excretion and serum creatinine level: Group 1 (n=30): normal renal function + urine microalbumin
