Sarcoidosis can affect two or more members of the same family, and the reported occurrence of such familial sarcoidosis is variable from 0.5 to 14%. Recently we have experienced familial sarcoidosis affected mother and daughter, for the first time in Korea. Mother was diagnosed as Stage II sarcoidosis 4 years ago by transbronchial lung biopsy and cervical lymph node biopsy with compatible BAL finding in our hospital. This time, the daughter was admitted with bilateral hilar enlargement and anterior uveitis. Even though she had positive tuberculin skin test and atypical BAL finding(lymphocyte: 61%, CD4/CD8: 1.22). Transbronchial lung biopsy and mediastinal lymph node biopsy revealed noncaseating epithelioid granulorna without AFB. Slit lamp examination of the eyes showed severe anterior uveitis. Systemic steroid therapy was started due to progressive uveitis with antituberculous medication.

Orbital neuroblastoma is the most common childhood metastatic malignant tumor almost always originating from the adrenal medulla; orbital primary origin is very rare. The authors experenced a case of orbital neuroblastoma. The patient was 3 year old Korean female child who was in apparently good health and no abnormalities noted of physical examminations when she developed ecchymosis of right lower lid. About two week later, she quickly developed a growing mass in the right lower orbital soft tissue. The mass was removed and his topathologically diagnosed as neuroblastoma. Radiotherapy was recommended. About 4 months bter, the patient was readmitted because of recurrence of orbital mass 3t the same site. At surgery, tumor was found invading inner and flooe wall of the orbital bone. The patient died of poor course of the disease, about one year after the onset of symptoms. It was suggested that this case was represented metastatic orbital neuroblastoma on histopathological base, but authors were unable to determine the primary site. A brief review of the related literatures is present.

Massive pneumopritoneum developing immediately following initiation of artificial ventilation is an unusual sign of lung barotrauma and must be distinguished from pneumoperitoneum following rupture of a hollow abdominal viscus. Besides, pneumoperitoneum occurring in a mechanically ventilated asthmatic patient can present a diagnostic dilemma as the usual signs of an intestinal perforation may be masked by steroid therapy, sedation or paralysis, or combination of all three. We report a case of massive pneumoperitoneum after initiation of mechanical ventilation in a child with severe asthmatic attack.

Long QT syndrome is a cardiac disorder of repolarization which is characterized by elctrocardiographic abnormalities including prolonged QT interval, T-wave abnormalities and polymorphic ventricular tachycardia known as Torsades de Pointes. Its clinical manifestation are recurrent syncope, seizure, and sudden death. Recently,we experienced Torsades de Pointes(TdP) by head-up tilt test in 24 year-old female patient presenting recurrent syncope and long QT interval. Beta-blocker and left cervicothoracic sympathetic ganglionectomy were not effictive, then we tried mexiletine. After mexiletine medication, the QT interval was significantly shortened and there was no more syncope.

BACKGROUND: For complicated appendicitis, in contrast to simple appendicitis, laparoscopic appendectomy (LA) is considered a relative or absolute contraindication because of the higher postoperative complication rate than that of open appendectomy (OA), especially, high incidence of intra-abdominal abscess. The purpose of this article is to assess the feasibility of LA for complicated appendicitis. METHODS: A retrospective review of 35 LA and 128 OA for the cases of gangrenous, perforated appendicitis, and periappendiceal abscess between May 1995 and June 1997 was performed. Patients were identified through the hospital pathology registry. We compared data from both groups with respect to operative times, postoperative pain, duration of ileus, length of hospital stay, and complication rate, with special attention to the incidence of intra-abdominal abscess. RESULTS: 1) The male:female ratio of LA (1:1.2) was significantly lower than that of OA (1:0.45) (p<0.05). There was no significant difference in the age distribution between both groups. 2) The mean operative time of LA (58.3 minutes) was significantly longer than that of OA (51.8 minutes) (p<0.05). 3) The mean number of injections of analgesics and the mean duration of ileus represented an advantage for LA (1.2 times and 1.8 days) than those of OA (1.6 times and 2.0 days). But these differences did not reach statistical significance. 4) The length of hospital stay of LA (6.5 days) was shorter than that of OA (7.8 dyas) (p<0.05). 5) Overall postoperative complication rate was lower in LA (11.4%) compared with OA (11.7) (p>0.05). But LA was associated with higher incidence of postoperative intra-abdominal abscess (3/35, 8.6%) than OA (3/128, 2.3%) (p=0.114). There was one serious intra-abdominal abscess in the LA, which required reoperation. The rest 2 cases in the LA and all 3 cases in the OA were treated conservatively. CONCLUSIONS: LA for complicated appendicitis could afford the merits of shorter hospital stay, reduced incidenceof wound infection, and comparable incidence of overall complication rate. To reduce the incidence of postoperative intra-abdominal abscess, copious irrigation and adequate drainage should be recommended.

Roux-en-Y reconstruction is an occasional occurrence of Roux-Y stasis syndrome, characterized by chronic abdominal pain, persistent nausea, and intermittent vomiting. Construction of the Roux limb requires transection of the jejunum, which disturbs normal propagation of pacesetter potential and evokes development of ectopic pacemakers in the Roux limb. Ectopic pacemakers in the Roux limb generate pacesetter potentials, which with their associated orally propagating contractions, result in slower transit through the Roux limb.To prevent the Roux stasis syndrome, a new operation has been designed that is similar to the standard Roux-en-Y gastrojejunostomy construction but theoretically without inherent motor pathophysiology. The authors designed a new unbalanced " Uncut Roux-en-Y" procedure to avoid postoperative blind loop syndrome and performed the procedures with staple occlusion of the afferent loop in 11 patients who required gastric resection and reconstruction, during a period of 6 months from April 1995 to September 1995. Results were summarized as follows. 1) 9 of the 11 patients( 81%) had excellent results with stable or increased weight and no stasis syndrome. 2) 2 patients(19%) had poor results with alkaline reflux gastritis or esophagitis. Both had documented staple line dehiscence. One of them was operated on and converted to a standard Roux operation, but died. The other one continued to loose weight but maintained a normal dietary pattern. 3) Unbalanced Roux technique worked well without harmful complications. 4) Reinforcing serosal sutures on the staple line could prevent a possible jejunal leakage in the case of staple line dehiscence and might prevent dehiscence of staple lines.

BACKGROUND: The results of recent reports suggest that mechanical bowel preparation before colonic resection and primary anastomosis may be unnecessary. To determine whether mechanical bowel preparation influences the incidence of postoperative complications following colorectal surgery, the records of patients who had undergone colonic or rectal resection were retrospectively reviewed. METHODS: Between March 1992 and October 1997, colonic resection and primary anastomosis without colostomy was performed on 56 patients. Among these, 27 patients had undergone mechanical bowel preparation (MBP) before surgery, and 29 patients had not. We compared the data from both groups with respect to wound infection, anastomotic leak, intra-abdominal sepsis and death. RESULTS: The postoperative complication and mortality rates were similar in the two groups. Wound infection occurred in seven patients (four with MBP, three without), and the incidence of wound infection was similar in the two groups (14.8% versus 10.3%, P=0.700). Wound disruption occurred in two patients (one with MBP, one without). Anastomotic leaks occurred in two patients who had undergone bowel preparation. The overall anastomotic leak rate was 3.6% (7.4% versus 0%), but the incidence of anastomotic leaks was not significantly different between the two groups (P=0.228). No intra-abdominal sepsis was clinically apparent in either group. There was one death, a patient who had undergone bowel preparation. The mortality rate was not significantly different between the two groups (P=0.482). CONCLUSIONS: We believe that mechanical bowel preparation before colonic resection and primary anastomosis may be unnecessary, so routine MBP should be further scrutinized.
