Livedoid vasculitis is characterized clinically by smooth or depressed ivory-white scars surrounded by hyperpigmentation and telangiectasia with or without preceding purpuric in-filtrated papules and plaques and histologically by intravascular deposition of fibrin. Its pathophysiology is still obscure. Many treatment modalities have been used, but results are not satisfactory. Recently, there have been experiences of successful treatments with danazol, a synthetic androgen. We used danazol in three patients who presented with livedoid vasculitis and were relatively resistant to treatments with aspirin and/or pentoxifylline. After 4 to 8 weeks, there was remarkable clinical improvement in all three patients.

BACKGROUND AND OBJECTIVES: Intracardiac electrocardiographic finding using as a guide for selective catheter ablation in patients with AV nodal reentrant tachycardia (AVNRT) is not specific. Therefore, we evaluated the efficacy and safety of the anatomical approach for catheter ablation in patients with AVNRT. MATERIALS AND METHOD: Among the patients diagnosed as AVNRT by electrophysiologic study, total 66 patients (M:F=26:40) were included in this study. In the right anterior oblique radiographic view, the septal annulus of tricuspid valve, extending from the most posterior region of the annulus adjacent to coronary sinus ostium (posterior) to His bundle recording site (anterior), was divided into posterior (P), mid (M), and anterior (A) sites. Radiofrequency (RF) energies were applied from the posterior part to the anterior part sequentially along the septal annulus of tricuspid valve until successful ablation. RESULTS: Successful anatomical sites were located in posterior (11 patients), mid (48 patients), and anterior (7 patients) sites. The most patients (62 patients) were treated with slow pathway ablation except 4 patients in whom fast pathway was ablated. Probable slow potentials were observed in 8 patients (12%, 3 in posterior sites and 5 in mid sites). Transient complete AV block followed by first degree AV block and delayed complete AV block was occured in one case whose ablation site was A1. And another 3 patients had postablation first degree AV block. CONCLUSION: In patients with AVNRT, the ablated pathway were different according to successful anatomical site. And RF catheter ablation of atrioventricular nodal reentrant circuit guided by anatomical landmark is safe and efficacious.

3 cases of giant cell tumor in the distal femur or upper tibia were treated by curettage and acrylic cement packing between October 1978 and May 1981. All were females. The postoperative courses were satisfactory with no recurrence or malignant change for periods of 16 months to 30 months. In one case, acrylic cement reinforced with tantalum wire was used because it is superior to acrylic cement alone in mechanical properties. The adventages of this method are: 1. The cautery effect of setting cement. 2. Avoidence of the need for large quantities of cancellous bone 3. The possibility of incorporating a prosthesis if the lesion is extensive. 4. Rapid mobilization. 5. Ease of early diagnosis of recurrence.

This study was undertaken at the department of Obstetrics and Gynecology, Chonnam University Medical School, to investigate the association between some of the risk factor and the incidence of intrauterine fetal growth restriction(IUGR). The studied population was selected from patients who admitted at Chonnam University Hospital during January, 1992 through May, 1997, with following criteria, Korean, singletone pregnancy with live birth and known gestational weeks with 28 or more. And then, the risk factors were analyzed in terms of maternal factor, placental factor, and fetal factor. The following results were obtained. 1) The incidence of IUGR was 6.1%. 2) The incidence of IUGR was higher at young aged mother and nullipara. 3) Only 39.1% of etiologic factors for IUGR was found to have known causes. According to the risk factors for IUGR, hypertensive disorder during pregnancy, anemia, cardiac disease, leukemia, and pulmonary tuberculosis were associated with increased incidence of IUGR. 4) The relative risk of IUGR was much higher in neonates born with congenital anomalies. 5) According to the placental causes of IUGR, placenta previa and placenta abruption showed some association with IUGR.

Trichilemmal carcinoma is a rare malignant neoplasm of the hair follicle, which is derived from or differentiates towards cells of the outer root sheath. We report a case of trichilemmal carcinoma in an 83-year-old female patient. She presented with a tender dome-shaped crusted papule showing a feature of cutaneous horn on the forehead, which was first detected 6 months before. nstopathologically, lobular patterned tumor cells with peripheral palisade of basaloid cells, nuclear atypia, and clear or pale, PAS-positive, diastase-sensitive cytoplasm were observed beneath the marked hyperkeratosis. After the diagnosis, total excision was done. The patient has been free of recurrence or metastasis till now.

Generalized syringoma is a rare variant of syringoma. In generalized syringoma, numerous papules arise in successive crops on the anterior surface of the body involving the chest, neck, and abdomen. It usually occurs in adolescents and young adults. Males and females are almost equally affected. A 19-year-old man presented with multiple 2-3mm sized papules on the chest, abdomen, and upper back. There was no subjective symptom. Family history showed that his mother had similar lesions. Histopathologic examination showed numerous eccrine ducts of various shapes and sizes lined by a double layer of squamous epithelium. Herein, we present a case of generalized syringoma with a review of the literature.

A silicone-covered modified Gianturco stent in patients with malignant esophageal stricture is an easy, safe, and effective palliative procedure, but reports of complications arising from stent placement in patients with this condition are numerous. There have been no reports of fracture of the modified Gianturco esophageal stent. We report a case of stent fracture in association with gastric migration of modified Gianturco esophageal stent in a patient with malignant esophageal stricture. It appears that the fracture was probably due to oxidation of the stent by gastric juice.

Recently, the incidence of fracture and dislocation of the proximal humerus has been increased with increment of traffic accident and industrial accident. Although most proximal humeral fractures can be treated satisfactorily by simple conservative treatment, the displaced fracture or fracture-dislocatiion of the proximal humerus demands special treatment and judgement. It has been reported that the results of the surgical treatment of the unstable fracture of the proximal humerus was better than that of conservative treatment. The authors analysed 32 cases displaced fracture or fracture-dislocation of the proximal humerus treated operatively which were followed up more than 1 year at the Dae Han Hospital from June, 1990 to May, 1993. The obtained results were as follows; l. According to Neer's classification, there were 2-part fracture in 3 cases(9%), 3-part in 17 cases(54%), 4-part in 2 cases(6%), fracture-dislocation in 8 cases(25%) and head splitting in 2 cases(6%). 2. The clinical results by Neer's criteria were excellent in 9 cases(28%), good in 14 cases(44%), fair in 7 cases(22%), and poor in 2 cases(6%) among the 32 cases. 3. The complication were limitation of motion in 4 cases, avscular necrosis of humeral head in 2 cases, nonunion in 1 case, delayed union in 1 case, ectopic ossification in 1 case and malunion in 1 case. 4. In the unstable fracture of the proximal humerus treated by accurate reduction and rigid fixation with intensive rehabilitation can be obtained, relatively satisfactory results because of the inability to maintain an acceptable closed reduction.

A thirty nine year-old male patient was scheduled for emergent craniotomy and epidural hematoma evacuation under general anesthesia. All data of the preoperative check lists for emergent operation were within normal limits and vital signs of the patient were stable. During the induction of anesthesia an armored tube was inserted into the trachea for this operation. Approximately 110 minutes after the induction of anesthesia, signs of complete airway obstruction developed abruptly. At that time we deflated the cuff balloon to exchange the tube. Then, the signs of airway obstruction disappeared completely. Therefore the deflation of cuff balloon is recommended in order to exclude the obstruction by the displaced cuff.
