PURPOSE: The artificial erection is critical to chordee repair. We report the use of a natural erection induced by prostaglandin E(1)(PGE1) in the diagnosis and treatment of penile curvatu re as an alternative to artificial erection in children and adult patients. MATERIALS AND METHODS: Pharmacological erection was induced 14 children with a mean age of 5 years (range 1-10) and 8 adults with a mean age of 33 years (range 18-58) to diagnose and repair anomalies, such as simple penile curvature, chordee with or without hypospadias, webbed penis and Peyronie's disease. Alprostadil (1-16ng) as a agent for induce erection was used exclusively, but no agents were routinely given to reverse the erection was used exclusively, but no agents were routinely given to reverse the erections. The dose injected intracavernosally was dependent on the patient's age, penile size and response, and ranged from 0.5 to 10 micrograms. Time to and adequacy of erection, detumescence, changes in blood pressure and pulse rate were monitored. RESULTS: A dilatation of erectile tissue was achieved within 8 minutes and was judged adequate in 2 and excellent in 20. The mean duration of erection was 107 minutes, while a prolonged erection, for up to 2.5 hours, occured on 2 patients who were treated conservatively. Detumescence were occurred when the corpora were opened, but re-erected penis after closure of corpora in 7 cases who treated with Nesbit's corporeal plication or fibrous plaque excision and dermal graft. Although there were the impression of increased bleeding, there were no specific changes in blood pressure or pulse rate. CONCLUSIONS: Pharmacological erection in penile curvature is effective and reliable with no significant complications. Although PGE1 is expensive and induced slightly increased bleeding, pharmacological erection has the advantage of tumescence of the entire penis and consequently a constant and natural representation of chordee without corporeal or urethral injury. Therefore, the erection achieved by injecting PGE1 into the corpora cavemosa is a useful alternative to artificial erection in the diagnosis and treatment of penile anomalies.

Smooth muscle hamartoma was first described by Stokes in 1923 as the disease characterized by increase of well-defined bundles of smooth muscle fibers in the dermis. It can be either congenital or acquired. Acquired ones are aften in association with Becker's nevus. We present a case of acquired smooth muscle hamartoma that did not show any pigmentation or hair growth.

PURPOSE: We evaluated a rapid preparation procedures for the labeling and quality control of 99mTc-ECD, MAG3, and MIBI using microwave heating and Sep-Pak cartridges. MATERIALS AND METHODS: 99mTc labeling of ECD, MAG3, and MIBI kit preparation was performed according to the package inserts with microwave heating modification. Heating time was 10-15 sec, and heating was performed with 3 mm plastic bottle with screw cap to prevent radiation contamination. Labeling efficiency was obtained with C18 or Alumina N Sep-Pak cartridges. RESULTS: The radiochemical purity of 93~96% for 99mTc-ECD and 95~99% for 99mTc-MIBI was obtained using Alumina N Sep-Pak cartridge. The optimum irradiation time of microwave method for 3 ml 99mTc-labeled radiopharmaceutical solution was 10 sec for 99mTc-ECD and 99mTc-MIBI, and 15 sec for 99mTc-MAG3. The RESULTS of quality control data with Sep-Pak cartridges were well correlated with TLC method. The total preparation time of these radiopharmcaeuticals was 5~6 min including quality control procedure. CONCLUSION: This study demonstrates that radiopharmaceuticals preparation by microwave heating and quality control by Sep-Pak cartridges can be efficiently utilized as an alternative to the recommended method by manufacturer's manual.

Sebaceous trichofolliculoma is a rare appendageal tumor that usually present as a solitary tumor mainly on the nose. Histologically it shows a large, irregularly shaped, centrally located cavity lined by squamous epithelium and radially arranged pilosebaceous follicles connected to the cavity. We describe a case of sebaceous trichofolliculoma in an 86-year-old woman who presented with asymptomatic skin-colored papule on her nose.

BACKGROUND: For the evaluation of infectious or inflammatory disease, Tc-99m HMPAO WBC scan has been used. But techniques involving radiolabelled leukocytes scan were difficult, and have failed to distinguish between bacterial infection and non-bacterial inflammation. To overcome this difficulty, we evaluated Tc-99m Ciprofloxacin in clinically suspected bacterial infection. METHODS: We used this agent for 31 patients who had suspected sites of infection. And then we compared the imaging results of these patients with those of radiolabelled leukocyte scan. RESULTS: There was no adverse effect. 29 patients was involved for the interpretation. Infective spondylitis was the most common suspected disease (41%). Bateriologic culture was positive in 10 patients. The most common organism was meticillin-susceptible S. aureus (5 cases). The sensitivity and specificity of Tc- 99m Ciprofloxacin was 83.3% and 66.6%, and those of Tc-99m HMPAO WBC was 62.5% and 83.3%, repectively. For the diagnosis of infective spondylitis the sensitivity of Tc-99m Ciprofloxacin was 80.0% and that of Tc-99m HMPAO WBC was 40.0%. CONCLUSOIN: Tc-99m Ciprofloxacin shows relatively high sensitivity and specificity. Tc-99m Ciprofloxacin was superior to Tc-99m HMPAO WBC for the diagnosis of infection in axial skeleton.

Polypoid cystitis is an unusual benign lesion characterized by the edema, congestion and inflammation elevating the vesical mucosa into papillary projections. It is rare in the absence of one of the following 3 recognizable causes: indwelling catheters, vesical fistula or chronic bladder irritation. We report a case of a rapidly growing, huge polypoid cystitis without identifiable cause in a 17-year-old female, who was managed by cystectomy with uterus preservation and orthotopic bladder substitution.

The causes of pyogenic liver abscess has been known as biliary tract disease or intrabadominal infection but the large proportions of the patients has no apparent underlying disorders. Recently colonic mucosal lesions were reported in patients with cryptogenic liver abscess and it has been suggested that colonic mucosal break may play a role in developing liver abscess in otherwise healthy patients. We experienced a patient of severe recurrent liver abscess complicated with endophthalmitis only 3 months after successful treatment of initial cryptogenic liver abscess and a polypoid colon cancer was discovered by chance. It seems prudent to proceed colonoscopic examination in patients with cryptogenic liver abscess especially when it is recurrent.

This study was performed to determine the incidence and serogroups of meningococcal disease in the Korean Army. From August 2000 to July 2001, we identified prospective cases in the Korean Army. Meningococcal disease was confirmed by isolation of Neisseria meningitidis or detection of its antigen by latex agglutination from cerebrospinal fluid (CSF) or blood. Polymerase chain reactions (PCRs) were performed in the crgA gene to identify N. meningitidis regardless of its serogroup, and then in orf-2 (serogroup A) and siaD (serogroups B, C, Y, and W135) respectively for serogroup prediction. During the study period, twelve patients (four meningitis and eight septicaemia) were identified. The annual incidence was 2.2 per 100,000 (95% confidence interval, 1.3-3.8) among 550,000 private soldiers. Latex agglutinations were positive to A/C/Y/W135 polyvalent latex, but not to B latex in all patients. PCRs of crgA gene were positive in ten patients, whose samples (2 isolates from CSF, 2 CSFs, and 6 sera) were stored. In PCRs for serogroup prediction, one isolate was serogroup A, and one isolate and two sera were serogroup C. The need for meningococcal vaccination would be considered in the Korean Army through the cost-benefit analysis based on the result of this study.
