A 23 year-old female with skeleto-dentoalveolar protrusion of maxilla, minor broken contact points between anterior teeth, and missing of lower 1st molars, has been treated with multibanded edgewise technique. After treatment of 14 months, she has gained functional overbite-overjet relationship and facial harmony due to the retraction of upper anterior teeth. Root resorption was slight. Especially, us ing the space of missed lower 1st molars instead of extracting lower premolars, expected and favorable results were obtained.

19 years old female had untreated Veau classification class II cleft palate with ectopic eruption of upper right lateral incisor and congenital missing of lower lateral incisors. Upper left lateral incisor, left first molar aid lower left first molar were root restswithperiapicalpathologiclesions. So all root rests were extracted and prosthodontic rehabilitation after orthodontic treatment was planned. She was treated by means of multibanded system with face bow. After 23 months all orthodontic correction were achieved and, as soos as debanding procedure was done she was referred to oral surgeon and prosthodontist for surgical operation and bridge construction.

Detection of tears of the posterior cruciate ligament (PCL) with MRI is usually based on the appearance of the ligament. However, other MRI findings may be useful in establishing the diagnosis. We assessed these associated injuries in the cases of complete tears of the PCL, reviewing MRls. We evaluated 26 patients who received PCL reconstruction with complete tear of posterior cruciate ligament from Feb 1995 to May 1997 retrospectively. We studied associated findings with PCL injuries. Anterior tibial plateau lesions were found in 15 of 26 cases (57.7%). Meniscal injuries were found in 8 of 26 cases (30.8%). Popliteus muscular injuries was found in 7 of 26 cases (26.9%). Capsular injuries were found in 2 of 26 cases (7.7%). Retinacular injury which has never been described in PCL injuries, was found in 7 cases (26.9%, P>0.05), Other ligamentous injuries were associated in 22 of 26 cases (84.6%). Medial collateral ligament injuries were found in 16 of 22 (61.5%, P<0.05) cases. The frequency of associated ligamentous injury and meniscal tear correlated well with results reported by other authors. The presence and location of bone contusions and fractures correlated with the mechanisms of injury; the anterior tibial plateau was the most commonly affected site. We concluded that the associated injuries were very helpful in diagnosing PCL injuries with MRI.

The purpose of this study is to determine whether magnetic resonance imaging(MRI) can assist in deci- sion-making in the treatment of acute posterolateral complex injuries. We reviewed retrospectively seven patients with acute posterolateral complex injury, among the 79 cases that had taken cruciate ligament recon- struction. MRI findings were then correlated with the results of examination under anesthesia or operi lateral reconstruction. Based on surgical and clinical findings, there were six complete and four partial posterolateral complex injuries. MRI was able to accurately describe the extent of injury in each case. All ten patients had concomitant anterior cruciate ligament tears, and seven were three posterior cruciate ligament injuries. The iliotibial band was avulsed from Gerdys tubercle in seven patients. In knees with complete tears, separation of the coronary ligament of the lateral meniscus was noted on MRI. A characteristic bone contusion on the anteromedial femoral condyle was present in nine patients. Popliteal tendon tearing was observed in eight cases, and biceps femoris was torn in six patients. In knee with complete tears, tears of the lateral collateral ligament complex was noted both on MRI and intraoperatively. A high-quality MRI in patients sustaining these injuries will assist the surgeon in directly applying surgical techniques in a timely fashion.

A case of pulmonary alveolar proteinosis is reported. Most of the alveolar spaces were filled with amorphous deep eosinohilic material which revealed strong positive reaction to periodic acid-Schiff staining. Electron microscopic observation of this material showed numerous lamellar bodies in the alveolar spaces and cytoplasms of alveolar macrophages. A part of them were concentric multilamellated type A lamellar bodies and the other were finger printlike type B bodies. Combined type A and type B lamellar bodies were rarely present. From the above features it is suggested that both type A and B lamellar bodies could be transformed one another and those lamellar bodies may be originated from pulmonary surfactant.

PURPOSE: To evaluate CT findings of internal hernia. MATERIALS AND METHODS: Three patients with internal hernia had abdominal CT scans and two of them had small bowel follow through examinations. The CT features of two patients with retroanastomotic and one patient with left paraduodenal hernia were evaluated and correlated with small bowel follow through examinations, and surgical findings. Two patients with retroanastomotic hernia had a history of subtotal gastrectomy with antecolic gastrojejunostomy. The diagnosis of internal hernia was made on the basis of surgical find ings in two patients of retroanastomotic hernia, and characteristic barium study findings in one patient of left paraduodenal hernia. RESULTS: The small bowel follow through examination showed small bowel loops gathered in a circumscribed mass in the left mid abdomen, and delay in passage through these loops. In case of left paraduodenal hernia, abrupt narrowing of the distal duodenum could be identified. The characteristic CT findings of all three patients were whorling of the mesentery and mesenteric vessels in the left mid-abdomen. In the patient with left paraduodenal hernia, after resolution of the gastrointestinal symptoms, a follow-up CT scan showed spontaneous disappearance of whorling of the mesentery and mesenteric vessels suggesting spontaneous resolution of the hernia. In the other two cases, upon exploration of the abdomen, dilatation of afferent duodenum caused by adhesion between ligament of Treitz and adjacent bowel walls, and retro- anastomotic herniation of the efferent loops were found. CONCLUSION: The usual diagnosis of internal hernia is based on the appearance of the small bowel follow through examination. However, we consider that the whorling appearance(we call it whorling sign) of the mesentery and mesenteric vessels on CT scan is also suggestive of internal hernia in patients under clinical suspicion.
