Successful manual reduction of locked metacarpophalangeal joints in fingers.

BACKGROUND: Many studies on the etiology and operative treatment of locked metacarpophalangeal joints in fingers have been reported, but there have been few investigations on manual reduction. The rate of success of manual reduction in previous reports has been low, and no consensus has been reached with regard to the best method of manual reduction. On the basis of our experience with operative treatment, we devised a safe method of manual reduction. METHODS: Between January 1987 and December 1995, we reduced a locked metacarpophalangeal joint in twelve female patients; every locked finger was successfully reduced, and complications such as fracture did not occur during manual reduction. The average duration of follow-up was five years and nine months (range, three years and two months to nine years and three months). RESULTS: Six patients had no recurrence of the locking. Four of the six remaining patients had one or two incidents of locking, had no alteration in the activities of daily living, and did not want operative treatment. The two remaining patients reported that they had incidents of locking several times a day, and they requested operative treatment as they were afraid of additional recurrences. One patient had an open reduction fifteen months after the initial episode of locking, and the other patient elected not to have an operation for personal reasons. CONCLUSIONS: We believe that our method of manual reduction should be used to treat a locked metacarpophalangeal joint in a finger and that operative treatment should be limited to patients in whom manual reduction is unsuccessful or the reduction is unstable.

Laparoscopic intervention for intrathoracic stomach in infants.

BACKGROUND: Intrathoracic stomach is an uncommon condition in infants. We report our experience managing such a condition successfully by laparoscopy in four patients. METHODS: Patients' ages at the time of operation ranged from 30 days to 14 months. In all cases, the intrathoracic stomach was easily pulled down into the abdominal cavity. The phrenoesophageal ligament was completely resected, and the enlarged hiatus was narrowed by intraabdominal suturing technique. The esophagus was wrapped with the mobilized fundus in a floppy fundoplication. Anchoring sutures were placed between the wrapping cuff and crura. RESULT: One patient had paraesophageal hernia (type 2), whereas the other had combined hiatal hernia (type 3). No adverse complications were observed in any of the cases. Symptomatic gastroesophageal reflux and radiographic recurrence of hernia were not seen in any case. The cosmesis was excellent in all cases. CONCLUSIONS: We conclude that laparoscopic repair for intrathoracic stomach is a safe and feasible method when preoperative evaluation is conducted adequately.

[Benefits of a community oriented fluoride mouth rinsing program].

The benefits of a school-based fluoride mouth rinsing in a community dental health program were evaluated. In village "M", children from 4 to 14 years old have been participating in a school-based fluoride mouth rinsing program since 1974. In addition, an informal association for dental health of children was inaugurated in 1975 to support the community dental health program. In village "K", there were no fluoride mouth rinsing programs. However, the usual dental health education conducted in all schools was similar in both communities. In order to compare these two communities, dental examinations were carried out in 1990. The total number of subjects from 6 to 14 years old was 331 in village "M" and 408 in village "K". In village "M" for longitudinal comparison, 12-year-olds, 1,054 in total, were examined annually from 1974 to 1990. The DMFT-index in all subjects in village "M" was 76.1% lower than in village "K". In village "M", the DMFT-index in 1990 decreased 79.0% compared to 1974. The economic benefits obtained through the caries reduction were evaluated. In 1990 the mean cost of dental treatment for subjects 14 years old was 27,840 yen per person in village "K" and 4,248 yen in village "M". The cost-benefit ratio was 18.8 and the cost-effectiveness ratio was 137 yen. These remarkable benefits from the prevention of dental caries appears to have been mainly obtained due to the participation of children aged 4 to 14 years old in a school-based fluoride mouth rinsing program.

[Prevention of postoperative recurrence of hepatocellular carcinoma by adjuvant locoregional chemotherapy].

Postoperative adjuvant locoregional chemotherapy was performed on patients who underwent hepatic resection for hepatocellular carcinoma with permeation of tumor into portal vein and/or into hepatic vein and/or intrahepatic metastasis to prevent recurrence. Twenty patients received intra-hepato-arterial infusion of chemotherapeutic drugs or Lipiodol, or transcatheter arterial embolization as adjuvant therapy, and 25 patients did not receive the therapy. There was no significant difference in the recurrence rate between the two groups, and disease-free-survival would not be improved significantly by adjuvant therapy. But the disease-free-survival was improved in patients who underwent relative noncurative hepatectomies. Median duration from the hepatic resection to the recurrence was prolonged by adjuvant therapy, but no significant difference was noted between the two groups. Serious hepatic injury was a side effect of adjuvant therapy in one patient. Therefore great care was necessary when performing the therapy. Further study on choice of the drugs and methods was considered necessary to obtain more effective therapy.

The herbal medicine Rikkunshi-to stimulates and coordinates the gastric myoelectric activity in post-operative dyspeptic children after gastrointestinal surgery.

Rikkunshi-to (TJ-43), a gastroprotective herbal medicine, has been used for the symptomatic relief of adult patients with dyspepsia. However, its mechanism has yet to be fully elucidated. The aim of this study is to evaluate the effect of TJ-43 on the gastric myoelectric activity in post-operative dyspeptic patients, whose symptoms persisted for over 1 year after gastrointestinal surgery. Electrogastrography (EGG) recordings were performed to calculate the biomechanical parameters on the dominant peak frequency (DPF). Eight pediatric patients with dyspeptic symptoms after gastrointestinal surgery were examined and six age-matched children without any dyspeptic symptoms were used as controls, and they were compared with nine age-matched children without any dyspeptic symptoms after gastrointestinal surgery as subcontrols. All patients exhibited symptomatic relief after the administration of TJ-43, and the mean symptom score decreased significantly after the treatment of TJ-43 over a 1-month period ( P<0.0001). The variability index (VI) and the percentage of normal waves (PNW) were calculated as irregularity parameters of DPF. The power ratio (PR) was calculated as a parameter of the gastric contractile activity. There were no significant differences in the VI and PNW between the controls and patients during the postprandial state after therapy, even though significant differences existed regarding those parameters between the controls and patients before the therapy. There were no significant differences in the DPF, VI, and PNW between the controls and subcontrols. Furthermore, PR exhibited a significant increase after therapy ( P<0.05). However, there was a significant difference in the PR between the controls and subcontrols ( P<0.05). Postprandial dip was observed in all control subjects, eight patients in the subcontrols, and two patients after administration of TJ-43, respectively. An abnormal gastric electrical activity therefore seems to be an important factor in the pathophysiology of post-operative dyspeptic children. The coordinating and stimulating effect of TJ-43 on the gastric myoelectric activity therefore seems to play an important role in the reduction of dyspeptic symptoms.

Congenital diaphragmatic hernia in identical twins.

The authors present a pair of identical twins with congenital diaphragmatic hernia (CDH) diagnosed prenatally, who underwent successful surgical repair. They were diagnosed as having CDH at 32 weeks' gestation and showed respiratory distress soon after cesarean section at 33 weeks' gestation. Both survived after scheduled perinatal management followed by surgery, for which the prenatal diagnosis of CDH was valuable.
