Bizarre parosteal osteochondromatous proliferation was first described in 1983, when Nora and his collegues reported 35 examples of a proliferative lesion involving bones of the hands and the feet. In 1993, Meneses reported 65 cases of this condition. A fourth of all the reported cases involved the long bones. It is important to identify the clinical, roentgenographic, and histologic characteristic to seperate it from other entities because it is a benign lesion with atypical microscopic features with a tendency to recur. Roentgenograms show a calcific mass attached to the underlying cortex having a broad base. Histologically, the lesion exhibites proliferative activity, irregular bony cartilaginous interfaces, and enlarged, bizarre, and binucleated chondrocytes. We reviewed the bone tumors, diagnosed in the KyungHee University Hospital, dated from 1984 to 1994. Five cases were revised to Nora's lesion, all of which were previously diagnosed as osteochondroma. The ages of the patients ranged from 12 to 57 years (median, 19 years), and all of them were males. Two cases involved the bones of hands and feet (metacarpal and talus), and 3 cases involved the long bones (humerus, fibula, and ulna). One lesion involving the humerus has a recurrence. No metastasis had been reported.

Twenty nine cases of wrist tuberculosis were reviewed(19 joint involvement cases and 4 tendon involvement cases) and twenty three cases were followed up more than one and half years. The mean follow up period was 26.7 months. Synovectomies were not satisfactory in cases of joint involvement and they were useful only in cases of tendon involvement. Arthrodesises were used for 16 cases of joint involvement and were satisfactory in 87,5 percent by Robin's criteria. Finger stiffness was most serious complication(initially, 8.7 percent and finally, 34.8 percent) and it is suggested that early motion of fingers after arthrodesis can prevent this complication.

BACKGROUND: Basal cell carcinoma(BCC) is the commonest type of skin malignacy, and its incidence is increasing. As a result, the number of cases requiring treatment by dermatologists may also be increasing. OBJECTIVE: The aim of this study was to clarify the presentation pattern of BCC and to assessce the surgical treatment used in the dermatological surgery clinics in Seoul National University Hospital and Seoul City Boramae Hosptial between 1994 to 1998. METHOD: We reviewed the medical records and checked clinical aspects and surgical treatment methods. RESULTS: The Total number of patients was 33. There were 21 Females and 12 males. The Mean age was 63.1. The most common anatomical site was the face and scalp(30 cases, 91%). The mean size of the tumor was 12.2 by 9.6 mm. BCCs were removed by complete surgical excision with a normal skin margin of 2 to 4 mm. The local flap was most commonly used to repair surgical wounds (55%) and primary closure was used in 39% of patients. A Pedicle flap and full thickness skin graft were also used in surgical defect reconstruction. CONCLUSION: With increasing public awareness and earlier presentation there may be a reduction in tumor size at the time of diagnosis. As most BCCs are found on the head and neck and are usually more or less than 1cm in diameter, it is thought that appropriate education of surgical skills should be needed and offered.

Lymphocytic hypophysitis is a rare but important cause of pituitary hypofunction which predominantly affects young women in the peripartum period. It is believed to be an autoimmune disorder with an association with other autoimmune disorders. Clinically, it presents most frequently with symptoms and signs attributable to pituitary hypofunction, headache, visual disturbance and amenorrhea. It is difficult to distinguish lymphocytic hypophysitis from a pituitary adenoma on preoperative imaging. So the diagnosis must be confirmed pathologically. The frozen section must be done for saving the risk of permanent hypopituitarism that would have attended a more radical debulking procedure. If lymphocytic hypophysitis is confirmed by frozen section, extensive surgical debulking may not be necessary. A 31-year-old woman presented during the third trimester of pregnancy in July of 2003 with headache, vomiting and gradually progressive bilateral visual loss. There was a large 8 shaped homogeneous sellar mass on MR images before delivery. The subtotal excision of tumor was done via transsphenoidal surgery three weeks after cesarean delivery. Visual field testing revealed marked resolution of her visual field defects in both eyes. We report a case of lymphocytic hypophysitis occurred in the third trimester of pregnancy with a brief review of literatures.

Inflammatory pseudotumor of the Aver is a rare benign lesion that usually has been discovered at laparotomy. This lesion is inflamrhatory and reactive, but the etiology remains unknown. In-flammatory pseudotumor of the liver is of the interest not only because of its rarity also because it needs to be clinically differentiated from hepatocellular carcinoma and other malignant tu-mors. In this report, we describe a case of inflammatory pseudotumor of the liver with fever and weight loss in a 46-year-old male. Grossly, the lesion showed a rather well demarcated, gray white to pale yellowish nodular mass mesuring 7 x 5.5 x 5 cm in dimensions. M icroscqpically, the tumor was composed of diffuse infiltration of predominantly plasma cells, lymphocytes and histocytes associated with fibroblastic proliferation.

BACKGROUND/AIMS: Risk factors for infection in patients undergoing hemodialysis during dual lumen catheterization have not been adequately defined. We investigated risk factors associated with Staphylococcal bacteremia (SB) in patients undergoing hemodialysis using a catheter. METHODS: Patients undergoing hemodialysis with a catheter were categorized into either the SB group (n=43) or control group (n=44). Data on patient demographics, the presence of underlying diseases, antibiotic use, APACHE II scores, and laboratory findings were collected retrospectively. RESULTS: Patients in the SB group tended to be older, and underwent dialysis upon admission more frequently, as compared with controls. In addition, the SB group had higher APACHE II scores, BUN, and lower creatinine levels upon admission, as compared with the control group. A multivariate analysis showed that dialysis upon admission was a risk factor for SB in patients undergoing hemodialysis using a catheter. Patients with Staphylococcus aureus bacteremia (SAB) also tended to be older and showed a higher incidence of both dialysis upon admission and antibiotic therapy prior to catheterization, as compared with the control group. Patients with SAB also had higher APACHE II scores, BUN and creatinine levels upon admission. Antibiotics prior to catheterization, higher creatinine levels, and dialysis upon admission were all independent risk factors for SAB. Patients with methicillin-resistant SB had lower albumin and creatinine levels than those with methicillin-susceptible SB. The incidences of catheterization in the general ward or ICU and antibiotic therapy prior to catheterization were both higher in the methicillin-resistant SB group. Catheterizations in the general ward or ICU and antibiotic therapy prior to catheterization were both independent risk factors for methicillin-resistant SB. CONCLUSIONS: In patients undergoing hemodialysis with a catheter, dialysis upon admission was an independent risk factor for SB. Additionally, antibiotic therapy prior to dual lumen catheterization was a risk factor for methicillin-resistant SB.

Preoyerative sedation of children is a difficult problem of great importance, for the psychic trauma comsequent to anticipation of surgery may be as great a hazard to the patient as his original disease. Until now, a number of sedatives have been used commonly for adequate sedation of pediatric patients, but, no method has been universally accepted. At our hospital fifty pediatric patients receiving general anesthesia for minor elective surgery were studied to evaluate the effect of ketamine hydrochloride as a preanesthetic agent. The results were as follows: 1) The onset of drag action was about, about 5min. 2) The induction of anesthesia and maintenances of operation was smooth, because a sedative effect was obtained without cardiovascular and respiratory depression. 3) With a small dosage of ketamine(2mg/kg), patients were free from apprehension. So, perioperative psychic trauma was preventible. 4) The two excitable patients were anesthetized by intravenous anesthetics with ease. 5) Mild complications, accurred but they were not significant.

BACKGROUND: Carcinoma of the uterine cervix is a theoretically preventable disease because its precursor lesions can be detected by cervical Papanicolau smears and appropriately treated, Although cervical cytology screening programmes have resulted in the redution of cervical cancer incidence and mortality, Pap smear have been subjected to intense scrutiny and criticism in recent years. The focus of criticism has been the false-negative Pap smear, and the false-negative Pap smear is the major quality issue currently facing the physicians. To reduce the false-negative rate of Pap smear, it is essential to improve the accuracy of Pap smear. But false-negative rate of Pap smear has been reported variously. OBJECTIVE: This study was undertaken to evaluate accuracy of Pap smear by study false-negative and false-positive rate of Pap smear and to determine whether false-negative and false-positive rate had any correlations with clinical factors. STUDY DESIGN: The study population was comprised of 346 women, who were undertaken gynecologic operation at the Department of Obstetrics & Gynecology at Hanyang University hospital between March, 1997 and April, 1998. All patients were taken Pap smear before operation. In 93 women of these, preoperative diagnosis were cervical intraepithelial neoplasia and carcinoma in situ of uterine cervix, and in 253 women of these, preoperative diagnosis were benign disease as uterine myoma or adenomyosis, etc. All of their surgical specimen were examined. Pap smear, pathology, medical charts of all patients were reviewed retrospectively, and false-negative rate and false-positive rate were calculated. Clinical factors that associated with false-negative and false-positive rate were evaluated. Fishers exact test and Pearson chi-square test were used of statistical analysis, RESULTS: False-negative rate of Pap smear was 7.2%, false-positive rate was 4.6%, corresponding rate with histology was 88.2%. Sensitivity and specificity of PAP smear were 87.0% and 97.0% respctively. According to gross finding of uterine cervix, erosion was 46.6% in cervical intraepithelial neoplasia, 67.8% in carcinoma in situ, 66.6% in microinvasive carcinoma of uterine cervix and 55.3% of 103 erosion findings was cervical intraepithelial neoplasia, carcinoma in situ or microinvasive carcinoma. 23.1% of cervical lesion were normal gross finding. Menopause was associated with false-negative rate and previous vaginal infection history, previous cervical minor operation, delivery mode, contraception method, pelvic inflammatory disease history, vaginal bleeding at Pap smear and gross finding of cerbix were not associated. There were no clinical factors that were associated with false-positive rate. CONCLUSION: Compared with other reports, false-negative rate(7.2%) and false-positive rate(4.6%) of Pap smear was lower and corresponding rate(88.2%) was higher in Hanyand university hospital. Because of higher false-negative rate in menopausal women, it need more careful to take and interpretate Pap smear in these group.
