INTRODUCTIONIn line with the effort to evaluate feasible surgical options for vasectomy reversal and to increase patients' willingness to undergo the procedure, this study reported on a technique for ambulatory mini-incision microsurgical vasovasostomy using a double-ringed clamp (i.e. Moon's clamp). This technique does not require the use of dilators, approximators and other accessory devices.

METHODSAmbulatory mini-incision microsurgical vasovasostomy was conducted on 263 patients who satisfied the surgical eligibility requirements for vasovasostomy and the safety criteria for local anaesthesia. The operation time, details on postoperative recovery and results of the postoperative semen analysis were recorded and retrospectively analysed.

RESULTSThe mean time used to isolate the bilateral vas deferens was 25.5 minutes. All patients were discharged on the day of surgery and all patients returned to their normal activities within 24-48 hours after surgery. No haematoma or infection occurred except in one patient. Postoperative semen analysis showed that the surgery was successful in 182 (96.8%) of the 188 patients who complied with the postoperative patient instructions.

CONCLUSIONAmbulatory mini-incision microsurgical vasectomy reversal using Moon's clamp and under local anaesthesia is a surgically feasible option that offers the advantages of a low-risk operation. It also achieves successful vasovasostomy without other accessory devices and allows patients to return to their daily activities quickly with minimal complications.

The MR images of 13 patients with brain abscesses were retrospectively reviewed. The abscesses were solitary in 11 patients and multiple in 2 patients. They were located in the corticomedullary junction of the cerebral hemispheres(11) and cerebellum (2).: The sizes of the abscesses were variable, ranging from 1 cm to 5 cm in diameter. They were round (5), oblong (4) or multilobulated (4) in shape. Massive surrounding edema was found in 12 patients. The signal intensity of the abscess contents was hypointense to gray matter and hyperintense to CSF on T1-weighted images, and hyperintense to gray matter on both proton-density-and T2-weighted images. In 5 patients the abscess contents were heterogeneous on both T1-and T2-weighted images. The signal intensity of the abscess walls was isointense(11), slightly hyperintense (1) or hypointense (1) relative to gray matter on T1-weighted images, whereas they were isointense (4) or hypointense (9) on T2-weighted images. Of 10 patients with Gd-enhanced-T1-weighted images, 5 patients(50%) showed thin, smooth, rim enhancement, while the other 5 patients revealed somewhat irregular thick wall enhancement Satellite or daughter abscesses were found in 6 patients. Meningeal or ventricular wall enhancement suggesting meningitis or ventriculitis was associated in 3 and 1 patient, respectively. In conclusion, the characteristic morphology and intensity of the abscess capsule, massive surrounding edema, satellite abscess and associated meningitis or ventriculitis are characteristics of the brain abscess, even though they are not entirely specific to allow for accurate diagnosis in all patients.

We retrospectively analyzed the Magnetic Resonance (MR) imaging findings in 41 cases of histologically proved malignant tumors of oral cariey. The diagnostic value of MR imaging in detection and delineation of the lesions was assessed. The value of MRI was compared with that of Computed Tomography (CT) in 14 patients. Thirty-four cases of 41 malignant tumors were squamous cell carcinomas. Adenoic cystic carcinomas (2 cases), malignant melanomas (2 cases), non-Hodgkin lymphomas (2 cases) and mucoepidermoid carcinoma(1 cases) were also included in this study. Most of the lesions were isointense or slightly hyperintense to muscle on T1 weighted images and showed variable degrees of high signal intensity on T2 weighted images. Two cases of malignant melanomas showed characteristic hyperintensity on T1 weighted images. T2 weighted image was better in detection and delineation of tumor in most of the cases. In 6 cases, Gd-DTPA-enhanced T1 weighted image was better than T2 weighted image. T2 weighted image was useful for the evaluation of deep tissue infiltration and T1 weighted image was useful for the evaluation of bone invasion and superficial tissue plane invasion. The lesion was detected only by MR in 3 cases of 14 in which CT was also performed. MR imaging was more sensitive in the evalustion of bone marrow involvement. MR imaging is very useful modality in evaluating oral cavity malignany and is superior to CT in delineation of the as well as in the evaluation of mandible invasion.

Myotonic dystrophy is an autosomal-dominantly inherited neuromuscular disorder characterized by slowly progressive muscular dystrophy, muscle weakness and myotonia. The clinical features may vary from just cataracts to involvement of multiple organ systems such as various muscles, heart, lung and intestine. During pregnancy and delivery, serious maternal and obstetrical complications may occur. The myotonia is often aggravated during pregnancy and it leads to obstetrical complications such as fetal loss, preterm premature delivery, hydrops, in-utero fetal death, difficulties in fetal expulsion, postpartum hemorrhage and/or anesthetic accidents. The affected neonate may display severe hypotonia, facial displegia and respiratory distress. This report presents a woman with myotonic dystrophy complicated with congestive heart failure and preterm delivery during pregnancy.

In complication of infective endocaditis splenomegaly and splenic infarction are not uncommon but splenic rupture is very rare. We report a case of splenic rupture complicated by infective endocarditis in 1 71-yr-old man who had been suffered from rheumatic heart disease (aortic regurgitation and stenosis and mitral regurgitation). The patient was admitted to mild fever and generalized weakness for 20 days. Diagnosis of infective endocarditis due to Staphylococcus epidermidis was made by clinical manifestaions and blood culture study.On 34th day of admissionthe patient suddenly displayed the symptoms and signs of massive intraperitoneal hemorrhage. Splenic rupture was revealed by paracentesis and radiologic studies. Rupture of spleen is an uncommon and usually fatal complication of infective endocarditis. Therefore early diagnosis and prompt treatment must be performed.

Pulmonary artery sling is an uncommon and potentially lethal vascular anomaly that can produce airway obstruction. Despite the availibility of a corrective operation, the mortality rate remains very high due to the high incidence of associated obstructive anomalies of the tracheobronchial tree. We experienced a 70-day-old male infant who was admitted to our unit because of sudden dyspnea, cyanosis, coarse expiratory wheezing and inspiratory stridor. At first, he was treated with bronchodilator and steroid under the impression of infantile asthma, but the symptoms went on without interval change. We performed magnetic resonance imaging study followed esophagography and two dimensional echocardiography. Finally he was diagnosed as a vascular sling. We report this with a brief review and related literatures.

Prepubertal male Sparague-Dawley rats were used to investigate the effects of unilateral testicular torsion on the contralateral testicular histology. All rats were divided into eight experimental group (5 animals each), one of which was used for experimental control (sham operation). We have examined contralateral testes to determine the effect of therapeutic orchiectomy or detorsion after active physical 720' torsion (six hrs., twelve hrs., twenty four hrs.) through hemi-scrotal incision, and the effect of torsion only for two weeks. The contralateral testes demonstrated significant decreased weights variously and smaller seminiferous tubular diameter in both the orchiectomy and detorsion groups compared to the torsion only group, and there was marked contralateral testicular alterations in the torsion only group compared to the control group. These studies indicate that testicular torsion will cause contralateral testicular damage, and these contralateral alterations may be caused by generalized perineal inflammatory responses rather than immunologic phenomenon.

Prediction of acetabular development after reduction in treatment of developmental dysplasia of thc hip (DDH) is earlier, the hetter results because it would help ensure optimal timing of additional procedure if necessary. In this respect, authors reviewed retrospectively the radiographs of the hips of 35 children with DDH who had unilateral involvement and treated hy senior author (S.H.Lee) from the heginning with single successful attempt of reduction. The radiographs which were made at the time of initial diagnosis, one, two year nfter reduction und final follow up were assessed of teardrop figures. The results of treatment were classified as satisfactory group(CE > 10degrees ) and unsatisfactory group(CE < 10degrees) judged hy center-edge angle(CE degrees) at final follow-ups. 1. The teardrop figures were classifiable into 4 distinct groups as i)absent. ii)V-shaped, iii)Ushaped, iv) inverted D-shaped. 2. The teardrop figures in normal sides of hip were all U-shaped. 3. In dislocated but with satisfactory result group(24 cases), absent at 2 cases(8%), U-shaped teardrop was seen at 13 cases(54%), V-shaped in 9 cases(38%), and inverted 2-shaped in 0 case at I year after reduction. 4. In dislocated but with unsatisfactory result group( 11 cases), they were mostly of V-shaped(7 cases, 64%). The rest were of ahsent in 4 cases(36%) . hut none of U-shaped and inverted 2-shaped. In conclusions, teardrop figures appeared as significant predictor of future development of hip joint. Teardrop figure which stay as V-shaped at one year after reduction seems suggestive of insufficient reduction of DDH, therehy calls for early additional procedure.
