The anterior interosseous nerve is the largest muscular branch of the median nerve and typically supplies the flexor digitorum profundus (radial part), flexor pollicis longus, and the pronator quadratus. Isolated paralysis in the distribution of the interosseou nerve of the forearm has been reported by several workers. This syndrome is distinguished by the absence of sensory involvement combined with partial median nerve paresis. This is a syndrome which is casily overlooked or misconstrued, unless the exact motor distribution of the anterior interosseous nerve is understood. We experienced a case following hard exercise in which the anterior interosseous nerve was compressed by the fibrous compression band on the underside of the flexor digitorum superficialis.

Since rupture of the Achilles tendon was first reported by Pare in 1575, various caues and diagnostic and therapeutic methods have been described by many workers. Almost all these workers agree that with early diagnosis and early treatment the prognosis is good. But the incidence of misdiagnosis by the physician as well as the patient's own neglect of his condition is disconcertedly high one. Nevertheless, negiected rupture of the Achilles tendon may lead to good results by proper selection of tbe operative method. In this report 16 cases of neglected ruptures of the Achilles tendon, in which treatment had been delayed more than 3 weeks were reviewed. A follow-up study of more than 6 months was made on 14 of these cases treated during the 5 year period from February 1973 to August 1977. The results are summarized as follows: 1. The causes responsible for the neglected ruptures were misdiagnosis by the physician in 62.5% and the patient's own neglect of his condition in 25% of the cases. The patient, in many cases, failed to seek medical treatment because of the rapid disappearance of pain, the absence of an open wound, ability of mild ankle plantar flexion, and the ability to walk. 2. Neglected rupture of the Achilles tendon occured most commonly in man of 4th decade. 3. Left side injuries were more common than right side injuries with a ratio of 9:7. 4. Ruptures by indirect injury were more common than by direct injury with a ratio of 9:7, and were most common during recreation and sports activities. 5. The most frequent site of rupture was 2 to 6 cm above the insertion of the tendon with 81% of the cases. 6. The end-to-end suture with pull-out wire method and Lindholm's operative method gave good (Excellent or Satisfactory) results in neglected rupture of the tendon as well. 7. Even in cases of neglected Achilles tendon rupture, normal function can be regained in approximately 6 months post-operatively if proper method of treatment is selected.

There are various factors affecting the fracture of NiTi rotary files. This study was performed to evaluate the effect of cross sectional area, pecking motion and pecking distance on the cyclic fatigue fracture of different NiTi files. Five different NiTi files-Profile(R)(Maillefer, Ballaigue, Switzerland), ProTaper(TM) (Maillefer, Ballaigue, Switzerland), K3(R) (SybronEndo, Orange, CA), Hero 642(R) (Micro-mega, Besancon, France), Hero Shaper(R)(Micro-mega, Besancon, France)-were used. Each file was embedded in temporary resin, sectioned horizontally and observed with scanning electron microscope. The ratio of cross-sectional area to the circumscribed circle was calculated. Special device was fabricated to simulate the cyclic fatigue fracture of NiTi file in the curved canal,. On this device, NiTi files were rotated (300rpm) with different pecking distances (3 mm or 6 mm and with different motions (static motion or dynamic pecking motion). Time until fracture occurs was measured. The results demonstrated that cross-sectional area didn't have any effect on the time of file fracture. Among the files, Profile(R) took the longest time to be fractured. Between the pecking motions, dynamic motion took the longer time to be fractured than static motion. There was no significant difference between the pecking distances with dynamic motion, however with static motion, the longer time was taken at 3mm distance. In this study, we could suggest that dynamic pecking motion would lengthen the time for NiTi file to be fractured from cyclic fatigue.

In order to reinforce the role of primary care physician and to improve doctor-patient relationship, the Korean government tried to introduce 'Family Doctor Registration Program' into Seocho-Gu in Seoul, Ansung-Gun and Paju city in Kyunggi-Do in Oct. 1996. Community residents and doctors in those area did not show much interest in this project because of low incentives. We have done this study to see how much people know 'Family Doctor Registration Program' and what is people's real needs about 'Family Doctor Registration Program. We selected l,800 telephone numbers in Seoul, Chongju city, and Ansung-Gun by multi-stage stratified random sampling. Three trained survey personnels called them and got answers to the premade questionnaire until they completed the questionnaires of 200 persons in each community. The calling time was 7-9 p.m. from Monday to Friday, 3-9 p.m. on Saturday, and 9 a.m. to 9 p.m. on Sunday. We dropped out the persons who did not respond 3 times. The subjects consisted of 222 male and 367 female residents. Their ages ranged from 20 to 78: 24.8% in their 30s, 23.4% in their 20s, 22.5% in their 40s in male, and 35.2% in their 30s, 22.5% in their 40s, 18.5% in their 20s in female. 9.9% of male and 13.2% of female had their Family Doctors. The specialties of their Family, Doctors were internists in 56.2%, general surgeons in ll.0%. The persons who did not have their family, doctors were asked which doctors they would prefer if they had choices of family doctor. The results were internists in 50.3%, family physicians in 13.0%, pediatricians in 4.8%. Only 16.0% residents knew that government tried to introduce Family Doctor Registration Program. The 'Family Doctor Registration Program' was not well known to people. The results of our study showed that more effective incentives and public notifications are needed to activate this program.

This is a clinical study of 30 cases of congenital malformation of ileum at Severance hospital from 1966 to 1975. They were confirmed after operation and the results were summarized as follows; 1. Total number of patients was 30 cases including 25 males 5 females. Among them 20 cases were included at pediatric agr from birth to 15 years of age. The most frequent occurrence was within 1 month of age with 11 cases. 2. Confirmed diagnesis after operation were 3 cases of ileal duplication,3 cases of ileal stenosis, 2 cases of ileal atresia, 1 cases of ileal hypoplasia, and 21 cases of Meckel's diverticulum. 3. Except for Meckel's diverticuium all the patients were studied which simple abdominal X-ray, which revealed complete and partial intestinal obstruction. Among them 4 cases were found microeolon and narrowing of distal 1 cases of ileum at 1 cases of ileal atresia and 2 cases. 4. After operation, 26 of 30 cases were recovered but 3 cases (atsesia 1, stenosis 1, and hypoplasia 1) were discharged with complications. And 1 case of multiple ileal stencelsdied of sepsis and wound infection.
