A case of pigmented villonodular synovitis developed in the right ankle joint is reported. The patient was a 25 years old house wife who had complained marked swelling and tenderness over the anterolateral aspect of the right ankle for 2 years. Roentgenological studies showed marked swelling of the ankle joint and erosion of the neck of the talus. Synovectomy of the affected joint was performed. The tumor mass, measuring about 7cm×5cm×2cm in size, was yellowish brown in colour, elastic and soft in consistency, and contained several well encapsulated nodules.

Buschke-Lowenstein tumor is a rare disease in the category of designated as verrucous carcinoma characterized by its invasive downward penetration of underlying tissues in the perineum and perianal regions. Viruses, unclean sanitation and cytotoxic immune reaction have been proposed as the etiology of the tumor. However, among all the causes, recent studies have emphasized on the associaton of the tumor and human papilloma virus (HPV). Expecially, HPV also has been discovered in several cutaneous and anogenital lesions of solid organ transplant recipients. We herein report a case of Buschke-Lowenstein tumor in a renal transplant recipient with HPV 6 and 16 coinfection proved by HPV genotyping of DNA extracted from the biopsy specimen of the tumor.

Background & PURPOSE:Since the 1970's the rate of breast-feeding has decreased significantly. The Korean National Institute of Health reported that the rate of breastfeeding was 68.9% in 1982 and 14.1% in 1997. There are many influencing factors including: the lack of education and information on breast feeding, lack of faith in breast feeding, increment of the rate of working, lack of encouragement by supporters in difficult situations, and nurses' low level of knowledge about breast feeding. Such a lack of knowledge and support of breast-feeding at home by family members create another dilemma to the problem of breast-feeding. If problems arise and family members are unable to provide assistance due to the deficiency of knowledge, mothers show a tendency to abandon breast-feeding. The purpose of this research is to find out the rate of breast-feeding practice by time sequence of 1 week, 6 weeks and 12 weeks after birth and influencing factors on breast-feeding practice centered on the postpartal women who were 3discharged from one hospital, which is located in Seoul and provides simple breast-feeding education and continuous postnatal telephone consultation. Methodology: The subjects of this research were 54 women who gave birth in a hospital located in Seoul from 1 March 2000 to 31 April 2000. After birth the subjects were educated individually about breast-feeding and telephone consultations were conducted. On the 1st week, 6th week, and 12th week, the subjects were surveyed about their breast-feeding practice rates and methods by telephone. Results: 1) Complete breast-feeding rate: Within one week after birth, the subjects showed 64.2% complete breast-feeding rate. Within 6 weeks, 39.6%, and 12 weeks, 34.1%. 2)Partial breast-feeding rate: Within one week after birth, the subjects showed 32.1% partial breast-feeding rate. Within 6 weeks, 39.6%, and 12 weeks 15.1%. 3)Complete bottle-feeding rate Within one week after birth, the subjects showed 1.9% complete bottle-feeding rate. Within 6 weeks of giving birth 15.1%, and 12 weeks 17.0%. These results show that individual education about breast-feeding and continuous postnatal telephone consultation influenced on the practice of breast-feeding. On considering the reality of the hospital situation in which nurses could not operate education program due to the work-load, it is necessary to find out selectively those mothers who are unable to breast feed and provide education individually and continuous support by telephone follow up. Futhermore, the active role of lactation nurse specialist and their efficient management of breast-feeding for the successful practice is required.

Palliative open nephrostomy was done on 50 cases with advanced pelvic malignancy and benign conditions in the Department of Urology, Seoul National University Hospital during the period of March, 1979 to July, 1982. The results were as follows: 1. 20.5% (9/44) of our patients died without being discharged from the hospital after nephrostomy. 2. In advanced pelvic malignancy, only 52.6% of patients alive at 3 months and only 26.3% alive 6 months. 3. In advanced pelvic malignancy, the post-nephrostomy complication was 46.7% and the most common complication was various urinary problems. 4. The cause of death was multifactorical and impossible to define precisely. The nephrostomy complications were at least in part contributory to the deaths. 5. The terminal malignancy patients who might not expected to live six months and to lead a useful, relatively comfortable life outside the hospital after treatment could not have benefited from nephrostomy. Unavoidable cases, we recommended percutaneous nephrostomy and passage of ureteral catheters instead of open nephrostomy.

This study was performed to investigate the effects of impression method and design of the retainer on the stress of abutment tooth in distal extension RPD. Three different types of direct retainer such as Akers clasp. RPI clasp, and wrought wire clasp were designed . Stress on the abutment tooth was measured and analyzed with strain gauge method. Impressions were anatomic impression technique and functional impression technique. The following conclusions were drawn from this syudy. 1.The stress at the abutment tooth on all RPD was decreased in functional impression except RPI clasp retained RPD. 2.The stress at the abutment tooth on RPI clasp retained RPD was the most smallest in anatomic impression 3.While load is increase the stress at the abutment tooth was increased, but the change of stress at the buccal side of abutment tooth was not too much in functional impression.

BACKGROUND: Crucial to the success of fiberoptic awake tracheal intubation is proper preparation of the patient; this technique will work well in most patients when they are quiet and cooperative and have a larynx nonreactive to physical stimuli. We have attempted to ascertain how well these conditions are achieved with a low-dose infusion of propofol, because of its pharmacological profile. METHODS: Thirty patients, physical status by American Society of Anesthesiologists (A. S. A.) I-II, scheduled for oral and maxillofacial surgery, were randomly assigned to receive either propofol infusion 1 mg kg-1 h-1 preceded by a 1 mg kg-1 bolus (Group P) or intravenous fentanyl 1ug kg-1 and midazolam 0.05 mg kg-1 (Group F). These two groups were compared in terms of hemodynamic profile, sedation score, condition for intubation, coughing and swallowing. RESULTS: There were no statistically significant differences in mean arterial blood pressures according to time between two groups. But in Group F, heart rates were significantly increased in immediately after transtracheal injection of lidocaine, immediately before the fiberoscopy was started, 1, 2 minutes after start of fiberoscopy, compared to Group P (p<0.05). The patients in Group P were more sedated than those in Group F (p<0.05) but there were no significant differences in condition for intubation, reflex of coughing and swallowing, duration of fiberoptic intubation. CONCLUSIONS: We conclude that propofol is useful sedative agent in fiberoptic awake intubation with similar efficacy to midazolam and fentanyl but with more profound sedation and stable hemodynamic profile. These represent significant advantages for severe anxious or hypertensive patients and prolonged procedure of intubation.

This study was aimed at investigation of the stimulatory innervations on the rat urinary bladder. Detrusor muscle strips of 15 mm long were suspended in isolated muscle chambers containing 1 ml of PSS maintained at 37℃ and aerated with 95% O²/5% Co². Isometric myography was performed, and the results were as followings: Muscle strips showed “on-contraction” by electric field stimulation (EFS) frequency-dependently. The EFS-induced contraction was not affected by hexamethonium, a ganglion blocker, but abolished by tetrodotoxin, a nerve conduction blocker. Physostigmine, a cholinesterase inhibitor enhanced the EFS-induced contraction which was inhibited by hemicholinium, an inhibitor of choline uptake at the cholinergic nerve ending. Such an EFS-induced contraction was antagonized by atropine only partially, and the atropine-resistant portion was completely abolished by the desensitization of purinergic receptors by prolonged incubating of the strips in the presence of high concentration of ATP. Bethanechol, a cholinergic agonist, elicited concentration-dependent contraction. Adenosine triphosphate (ATP), a purinergic agonist, induced a weak but concentration-dependent contraction of short duration. Bethanechol-induced contraction was not affected by ATP-desensitization, and ATP-induced contraction was not affected by tetrodotoxin. These results suggest that there are at least two main stimulatory components of innervations in the detrusor muscle, cholinergic muscarinic and purinergic; and those receptors are independent each other.
