Various devices have been introduced in the field of orthopaedic surgery for the treatment of fractures and dislocations. Widely used among these are metallic nails and pins. A rare complication is the migration of such intermal fixation devices from their original sites of insertion. Examples of migration have been shown in cases for which devices like Kirschner wire and Steinmann pin were used. Acromio-clavicular joint dislocation gives us another good example. Kuntscher nail has beenin worldwide use for the treatment of femoral shaft fractures since the original work of Kuntscher in 1940. Yet few cases were reported, for migration & Kuntscher nail. We, recently had an experience of proximal migration of a Kuntscher nail in a femoral shaft fractnre which was markedly comminuted. The case is presented here with references.

Introduction: Several investigators demonstrated that routine nasogastric decompression after abdominal surgery was unnecessary and can be safely eliminated. Some authors suggested that early feeding could be tolerated by the majority of patients after elective colorectal surgery. PURPOSE: The aim of our study was to prospectively assess the safety and tolerability of early oral feeding after colorectal surgery. METHODS: This trial included 69 patients who underwent an colon or rectal operation between April 1997 and August 1998. Patients were randomized after the operative procedure into one of two groups. Group 1: early oral feeding-all patents received a clear liquid diet on the first postoperative day followed by a regular diet as tolerated. Group 2: delayed feeding-all patients were treated in the traditional way with feeding only after the resolution of their postoperative ileus. Both groups had intraoperative nasogastric tubes that were removed at the end of surgery. The patients were monitored for vomiting, nasogastric tube reinsertion, time of regular diet consumption, complication, and length of hospitalization. The nasogastric tube was reinserted if two or more episodes of vomiting of more than 100 ml occurred in the absence of bowel movement. RESULTS: Sixty-nine consecutive patients were studied, 34 patients in group 1 (12 males and 22 females, mean age 58.1+/-12.7), and 35 patients in group 2 (16 males and 19 females, mean age 58.5+/-12.7). Significant differences were not noted in age and type of procedures. No significant differences were seen in rates of vomiting and overall complications. However, early feeding group well tolerated a regular diet (postoperative period to take regular diet of group 1: 5.4+/-4.0 days, group 2 : 8.1+/-4.6 days, p=0.013), and were discharged from hospital significantly earlier than the delayed feeding group(group 1: 14.0+/-5.1 days, group 2: 19.1+/-8.6 days, p=0.004). CONCLUSION: Early feeding after colorectal surgery is successfully tolerated by the majority of patients and led to earlier hospital discharge.

This paper is studied for statistical anaIysis of 1181 cascs of positive V.D.R.L test among 24414 cases who were visited for annual Physical examination and in or outpatients in the Han Gang Sung Shim Hospital during 5 years and 7 months from January 1972 to July 1977. Clinical survey was carried out with 182 syphilitic patients in the Department of Dermatology, Han Gang Sung Shim Hospital during 19 months from January l976 to July 1977. The results were as follows; 1. Positive rate for V.D.R.L test was 4.8%, and there were statistically significant differences in annual incidence(P<0.01). Biologic false positive rate for V.D.R.L test was 26. 7%, and there were statistically aignificant differences in annual incidence(P<0.01). 2. Departmental analysis such as Dermatology, Urology, Physical Examination and others including Obstetrics and Gynecology, Internal Medicine, Pediatrics etc. were carried out, the results showed that there were statistically significant departmental differences in V.D.R.L positive rate, but no in biologic false positive rate. 3. Biologic false positive rate was high inversely proportional to dilution titer, and that was a statistically significant difference(P<0.01). 4. 182 had syphilis, of whom 106(58. 2%) were latent syphilis and 74(40. 7%) were primary and secondary syphilis. 5. 119(65. 4%) among 182 syphilitic patients were male, most of patients(87.8%) occured in age from 21 to 40 years in the both sex. But there no statistically significant differences in age distribution between males and females. 6. The most predilection site of chancre was coronary sulcus(54.5%). 7. The lesions of secondary syphilis were composed of 18 cases(25%) of condyloma latum, 17 cases(23. 6%) of roseolar syphilid, 17 cases of papulo-squamous syphilid, 13 cases of alopecia syphilitica, 1 case of pustular syphilid, and 6 cases of others. 8. Married patients were nearly two times than single. In women, married. patients were much more(80. 3%) than single, and there were statistically significatnt differences(P<0.01). 9. There were no significant differences in S.T.S positive rate of spouse between infectious and latent syphilis. 10. Occupation distribution of male sexual partners were composed of 35 cases(29. 4%) of waitress, 28 cases(23. 5%) of call-girl, 20 cases(16. 8%) of office-girl, 17 cases of housewife, 12 cases of out of work, 7 cases of student. 1I. For patients with primary, secondary, and latent syphilis, treatment consiste of benzathine penicillin 2. 4 million units intramuscularly on the first visit and repeated three penicillin preparations at 7 days intervals in most of patients.

We examined sixty-three human embryos ranged from three weeks to eight weeks of fertilization age and 117 human fetuses from eleven weeks to fourty weeks of gestational age. Anatomical structure of developing tongue could be classified into eight developmental stages. The first is the sgage of mesial swelling of tongue primordium in the fertilization age of 28~40 days (Streeter stage 13~16), the second is the stage of lateral swelling of tongue primordium in the fertilization age of 41~46 days (Streeter stage 17~18), the third is the sgage of vertical positioning of tongue in the fertilization age of 47~53 days (Streeter stage 19~21), the fourth is the transitional stage of tongue from vertical position to horizontal position in the fertilization age of 54~56 days (Streeter stage 22~23), the fifth is the stage horizontal positioning of tongue in the gestational age of 11 weeks, the sixth is the stage of protrusion of tongue in the gestational age of 12 weeks, the seventh is the stage of maturation of tongue muscle in the gestational age of 7-10 months. The development of tongue papilla characteristically progresses into three stages. The first stage is the epithelial ingrowth for the crypt formation, the second stage is the anatomical formation of vallate, fungiform and filiform papillae, and the third stage is the differentiation of taste buds in the vallate and fungiform papillae or the formation of thick spike-like keratinization at the tip of filiform papilla. We observed that the tongue primordium mainly derived from occipital myotome developed more repidly than other oro-facial structures, so it transitionally occuied the spaces of the pharynx and the posterior nasal cavity, and directly affected the formation of palate and the growth of maxilla and mandible. Whereas the tongue papilla development showed continuous developmental sequences during the fetal period.

BACKGROUND: Maritime medicine refers to the medical care and education of medical disease which may develop during a cruise. Recently, cruise passengers are increasing around the world and maritime medicine has been initiated in Korea with beginning of the trip to Mt. Kumgang in 1998. Nowadays, there are about 4,000 passengers per week. Therefore, the data were analyzed to promote the understanding of maritime medicine, which was first applied on the Mt. Kumgang cruise, and to help the medical members who will be participation in the maritime medicine in the future. METHODS: From November 1998 to February 1999, all patients who visited to medical cabin of the cruise ship(Hyundai Pongnae) were analyzed retrospectively. RESULT: 2,162 patients excluding 182 patients who re-admitted were analyzed. In each cruise, there were 65.5(9.0%) passengers and 42(13.0%) crews. The male to female ratio was 1.6 : 1, with 709 males and 451 females. The common problems were respiratory and musculoskeletal diseases followed by dematologic and gastrointestinal problems in order of frequency. There were 18 patients who had trauma above 4 points in ISS. Ten patients were confined to the medical cabin. The ship returned to Donghae-port one time, 8 patients were evaluated immediately and 41 patients were referred without urgency. CONCLUSION: Maritime medicine has a particular characteristic of dealing with various cases and treatments including emergencies with limited space, man-power, facilities and equipment. It obviously proposes the participation emergency medical doctors in the maritime medicine because medical personnel must take part in not only medical management but also in education and prevention including CPR. The medical staff in charge of maritime medicine should establish a proper plan depending on the purpose of the cruise and must endeavor to solve the problem.

Korean Journal of Pathology 1989;23(2):235-239
Five fetal maxillas were obtained from the autopsy file of fetal postmortem examination, and were examined by serial micro-sections of frontal plane and horizontal plane. Especially the area around the incisive canal of the maxilla was carefully observed. The results are as follows. 1) In 5 fetal maxillas extra-dental laminas and supernumerary tooth germs which are severely malformed in shape are found in the dilated incisive canal, where prominent vessels and nerves are distributed. 2) The supernumerary tooth germs disclose almost normal histo-differentiation of odontoblast and ameloblast, and there shows relatively abundant perifollicular fibrosis in the place of perifollicular bone. 3) It is observed that the over-growth of the extradental lamina from the dental ridge of deciduous central incisor frequently tends to direct toward the incisive canal that includes prominent vessels and nerves.

The Journal of Korean Academy of Prosthodontics 2000;38(4):472-483
Before impression making in the fixed restorations or other prosthesis, hemostatic solutions are used for hemostasis and moisture control. Hemostatic solutions effectively control bleeding but their major ingredients, acid removes smear layers which are formed in the tooth preparation, exposes the dentinal tubular orifices which are occluded by smear layers, makes dentinal tubular fluid displace more easily to the various external stimulus, and according to the hydrodynamic theory, consequently causes dentin hypersensitivity. To know the effect of hemostatic solutions on dentin permeability, coronal dentin discs, 1 mm in thickness, were prepared from extracted third molars free from decay and wear, and a spilt chamber device was used. Hydraulic conductance values and SEMs, which were measured before and after treatment with Astringedentr , Altract and Epri-dent , were compared and analyzed. The following conclusion were drawn : 1. Hydraulic conductance values which wee measured after the treatment of hemostatic solutions were increased in all groups(p<0.05). 2. %change values of hydraulic conductance were compared but no significant difference was found among the three hemostatic solutions(p<0.05). 3. on SEM observations of all groups, after treatment smear layers were removed and dentinal tubular orifices were partially exposed. on the basis of these conclusions, the reckless use of hemostatic solutions should be restricted, and when in use, various methods should be considered to protect dentin.
