The medial collateral ligament is the most commonly injured ligamentous structure of the knee. The management of the medial collateral ligament injuries were divided into surgical and conservative treatment. More recently, many investigators reported that isolated medial collateral ligament injuries did well under non-operative treatment. So, arthroscopic examination of the knee to rule out other intraarticular pathologic conditions such as cruciate ligament injuries, meniscal tear and osteochondral lesion is essential. From October 1993 to April 1995, we treated 45 cases of Grade III medial collateral ligament injuries and arthroscopic finding for cruciate ligament, meniscus, bony structure were analized in these cases. The result were as follows; 1. Anterior cruciate ligament injury:37.5% in +1 degree, 42.8% in +2 degree, 86.7% in +3 degree 2. Posterior cruciate ligament injury:12.5% in +1 degree, 13.4% in +2 degree, 33.3% in +3 degree 3. Meniscal injury:12.5% in +1 degree, 21.3% in +2 degree, 33.4% in +3 degree 4. Medial capsular ligament injury was more frequent and severe in the meniscofemoral ligament than in the meniscotibial ligament, but that finding was not correlated with degree of medial instability.

Atrial flutter is and infrequent, but potentially unstable tachyarrythmia that occurs in pediatric ages. Transesophageal atrial pacing was used for treatment of 10 episodes of atrial flutter in 7 patients. At the time of atrial flutter conversion, patients were 6 days to 14 years old. 6 patients had associated with congenital heart disease. The atrial cycle length of atrial flutter ranged from 140 to 280 msec with variable atrioventricular conduction. Transesophageal atrial pacing was performed using a bipolar 4 F transesophageal electrode catheter. Atrial flutter conversion was accomplished with stimulation bursts using about 5 seconds of stimuli, 10 msec in duration at 20 to 27 mA. Pacing cycle length was 45 to 110 msec less than the atrial cycle length of tachycardia in 6 episodes. But in a neonate, underdrive pacing converted atrial flutter to sinus rhythm. Conversion attempts were unsuccessful on 2 occasions. Transesophageal atrial pacing is a safe and effective, minimally invasive technique for treatment of atrial flutter in infants and children.

Juvenile granulosa cell tumor is rare but one of the common congenital testicular neoplasms. Although histological features are typical of its ovarian counterpart, testicular juvenile granulosa cell tumor has a distinctly different clinical presentation. We report a case of juvenile granulosa cell tumor arising in the cryptochid testis of a 4-day-old newborn. A 6 5 5 cm sized multilocular cyst containing thick, mucinous fluid was found in the peritoneal cavity. The external surface of the cyst was smooth and the septae were relatively thin. The cyst consisted of numerous mucin-filled, cystic follicles lined by cells having vacuolated cytoplasm and round to oval dark nuclei without grooves. Cells resembling granulosa cells of an ovarian follicle were also observed in the intervening stroma forming irregular solid nests.

BACKGROUND: Although most dermatologic laser systems were developed to damage target tissue selectively, the epidermal injury has been a major problem in treating skin lesions of colored people. Recently, to minimize the epidermal damage during laser treatment, superficial cooling is being used. Cooling is one of the well known methods to reduce pain sensation. OBJECTIVE: The purpose of this study was to evaluate the effectiveness of an air cooling in reducing pain associated with Q-switched Nd:YAG laser and pulsed dye laser treatment. METHODS: We measured the temperature of normal skin during air cooling and studied 13 patients treated with a 1064 nm Q-switched Nd:YAG laser or 585 nm pulsed dye laser treatment with and without air cooling system. The degrees of pain reduction rates with and without cooling were assessed by the visual analogue scales. RESULTS: 1. It was shown that cold air flow from 2 cm distance for 10 sec decreased skin temperature about 10.6 degreeC to 17.2 degreeC depending on the body sites. 2. The average of the pain scores was 38.08+/-21.05 on the cooled site as compared to 70.77+/-15.76 on the uncooled site. CONCLUSIONS: The cold air decreased the skin surface temperature like the other epidermal cooling system and it was very effective to reduce the pain on the cooled site associated with dermatologic laser treatment.

Tumorlet is a rare lesion of disputed origin that was first described by whitwell in 1955, and about one-third of the reported cases have been associated with underlying lung disease. Patient was a 60-year-old female who was admitted with a histroy of chest discomfort and dyspnea. Right lower lobe was partially resected under the clinical diagnosis of the bronchogenic cyst. Grossly, lung tissue around round cystic lesion appeared brown firm and somewhat fibrotic, and showed several scattered ill-defined whitish gray nodules. Microscopically, lung tissue around bronchogenic cyst was partially obliterated by dense fibrous scar tissue. Within this areas of fibrosis, and in the wall of alveolar ducts and respiratory bronchioles, innumerable microscopic tumorlets were found and argyrophilic granules were also demonstrated in scattered tumorlets with Grimelius stain.

Pseudoaneurysm due to chronic pancreatitis is uncommon, but it can cause recurrent and massive hemorrhage. Because of high morbidity and mortality associated with the pseudoaneurysm, early detection and treatment is essential. Surgical ligation or resection of the aneurysm has a high mortality and therefore, transcatheter embolization is preferably carried out. We report a case in which gastroduodenal artery pseudoaneurysm caused by chronic pancreatitis was successfully treated by transcatheter embolization using Gelfoam and Gianturco spring coils.

We compared cycloplegic refraction after convenient, less toxic single-dose atropinization with conventional three-day atropinization in esotropic children. We examined sixty children below eight years of age with esotropia. Their eyes were examined by cycloplegic refraction at 90 and 120 minutes after administering a drop of atropine twice at five minutes interval. After eight applications for three days, we performed cycloplegic refraction of their eyes. In the two groups, spherical equivalent and spherical power were statistically significantly different, and it had no statistical significance between the measurement of single-dose atropinization plus 0.5 diopter and three-day atropinization. The side effects were found lesser in single-dose application than conventional three-day applications. The results showed that single-dose atropinization can be substituted for conventional three-day atropinization in clinical practice.
