Agenesis of the dorsal pancreas is one of the rare congenital anomalies of the pancreas. Six cases of them have been reported. We have experienced an autopsy case of agenesis of the dorsal pancreas associated with fetal death in the uterus. Grossly, the body and tail of the pancreas and uncinate process were not found and those were partially replaced by adipose tissue. No abnormality was noted in the other organs. Microscopically, pancreatic tissue with autolytic change was identified only in the head portion of the pancreas.

A 10-year-old boy had a recurrence of cutaneous lesions 1 week after only one exposure to jellyfish on the lower extremity. The recurring lesion was charaeterized by pruritic several linear or whiplash-like erythematous and some edematous papuloplaques. The histopathologic findings showed focal hyperkeratosis, acanthosis in epidermis and mild perivascular infiltration of inflammatory cells, capillary proliferations in dermis.

We report herein a case of smooth muscle hamartoma associated with Beckers nevus in a 5-year-old female. The child presented with a slight.ly brownish. 2 x 3 cm sized, pigmentecl patch with follicular accentuation on the right forearm, witch had been observecl since age of 2. Histopathologic findings showed the epidermal changes most consistent with Becker's nevus and the presence of irregularly arranged hyperplastic smooth muscle hundless in the dermis.

We performed an epidemiologic survey to investigate the dermatologic problems from cutting oils in metal workers. The personal questionnaires and dermatologic examinations were performed on 360 metal workers who were working at 50 metal industries. The pH meter (HANNA 8520) and the atomic absorption spectrometer(G.B.C. 902) were employed to measure the pH values of cutting oil and the concentration of heavy metals contained in cutting oil respeetively. The results were as follows : 1. The prevalence rates of the dermatologic disorders from cutting oil were 46.0% of eontact dermatitis, 10.9% of black comedone, and 7.1% of paronychia in orders. The dermatologic disorders that seemed to be not directly associsted with cutting oil were callosity(19.1%), burn by metal chips(9.8%), and mechanical injury(5.7%). 2. The localizations of the contact dermatitis and the black cemedone from cutting oil were 84% of hands, 6.6% of face, and 5% af forearms. More detailed localizations of the contact dermatitis and black comedone that developed in hand were 29.6% if finger tip, 27.6% of palm and palm finger, and 19.1% of palm finger only in orders. 3. The prevalence rates of the dermatologic disorders by the of cutting oil were 51.5% of soluble oil, 68.8% of insoluble oil, and 80.8% of mixed cutting oil which containing both soluble and insoluble oil. 4. The mean pH value of aoluble cutting oil was 8.0 and that of insoluble cutting oil was 7.0. 5. The concentrations of heavy metals contained in soluble oil were 32.2 mg/m3 of chrome, 6.42 mg/m3 of nickel, and 4.85 mg/m3 of cobalt. The concentrations of heavy metals contained in inspluble oil were 24.11 mg/m of chrome, 4.63 mg/m3 of nickel, and 2.30 mg/m3 of cobalt.

The injured skull bone may be contaminated in compound frontal skull fracture, so definitely left out for the prevention of infectious complications in the classic concept. The efficacy of primary replacement and resection of the injured bony fragments in the treatment of compound depressed frontal skull fractures was studied in 33 patients who could be followed up over one year during a recent 5-year period. The patients was divided into a group I which took a primary replacement of injured bony fragments and group II which left out the injured bony fragments in immediate operation. The results are summarized as follows : 1) The age incidence was more frequent in the 3th and 4th decades. The sex distribution was more frequent in male(87%). 2) The motor vehicle accident was most frequent in the injury mechanism. 3) The conscious level on admission was 53% in 13~15 GCS group, 12% in 9~12 group, 26.6% in 6~8 group and 8.4% in 3~5 group. 4) The incidence of an extending fractures was 42% to orbital roof, 35% into frontal sinus, 25% into cribriform plate and 16% into nasal bone. 5) The incidence of intracranial injury was 65% in dural laceration and 51% in cerebral laceration. Of cases of dural laceration the cerebral laceration was associated in 78%. 6) The time duration from injury to operation was under 12 hours in most cases(84%). 7) The incidence of a complication was 36.1% in total group, 27.7% in group I and 47.2% in group II. The infectious complication was not a significant difference between group I(14.9%) and group II(16.7%). In conclusion the infectious morbidity of which were most dangerous complications due to compound depressed frontal skull fractures was not a significant difference in two compared group. The author believe that immediate bone replacement for compound depressed frontal fractures with or without extension to frontal sinus, orbit, or cribriform plate os both practical and safe procesures.

Myelopathy or dysfunction of the spinal cord, can be caused by degenerative processes of the cervical vertebrae. Cervical spondylotic myelopathy can be divided into five distinct syndromes on the basis of clinical presentation by Ferguson. Absolute indication for surgery is the progression of neurologic deficit. Decompression may be achieved using an anterior, posterior, or a combined approach, but each patient has unique clinical conditions that require individualized treatment. The purpose of the study was to evaluate the operative results by the clinical manifestation. In evaluating the results, the evaluation system established by the Japanese Orthopedic Association was employed. The average preoperative score in the 14 patient was 8.7 points and the average postoperative score was 12.7 points. The better results have been obtained for those who were managed with decompression within 1 year after onset of symptoms and those who had lateral type. In conclusion, the prognosis for the recovery of the spinal cord function is related with the onset of clinical symptoms and degree of neurological deterioration, so early detection and operative decompression for cervical spondylotic myelopathy may be the best method for the prevention of those unwanted and potentially devastating neurological deteriorations.

Isolated dislocation of all five carpometacarpal joints is extremely rare, only eleven cases had been reported since 1873. In Korea, we have not seen it probably. We experienced one case of isolated dislocation of all five carpometacarpal joints with a good result in I year after closed reduction and internal fixation.

Isometric positioning of the ACL graft is an important consideration in successful reconstruction of the ACL-deficient knee. The purpose of this study is to get a certain guideline in the endoscopic one-tunnel technique of anterior cruciate ligament reconstruction by measuring the skin angle and determine the degree of minimum flexion of the knee joint during femoral tunneling and interference screw fixations. To get the guide lines, first we get the tibial tunnel angle parallel to the Blumensaat's line from fully extended lateral knee joint radiography. Secondly measure the differences between angles of the femur-tibia shaft and anterior thigh-leg skin. Then measure the minimum femur-tibia flexion angle does not perforated the posterior cortex of the distal femur during femoral tunneling. Intraoperative measuring the angle between interference screw guide pin and tibial tunnel to get the parallelism of the femoral tunnel and interference screw. The results were as follows; The average femur-tibia shaft angle with 30degrees anterior thigh-leg skin angle was 30.2+/-1.75degrees, with 45degrees was 45.2+/-1.23degrees, with 60degrees was 61.9+/-4.23degrees, with 75degrees was 78.6+/-2.62degrees, with 90degrees was 97.8+/-3.96degrees. Predetermined sagittal tibial tunnel vector on the 0degrees extension knee joint lateral radiographs were applied to the several knee joint dynamograms. The mean minimum flexion angle of the femur-tibia shaft that doesn't perforate the posterior cortex of the femur was 45+/-1.58degrees (male), 44.5+/-4.97degrees (female). The average angle between interference screw guide pin and tibial tunnel was 23.0+/-2.23degrees. The findings of the present study suggest that anterior thigh-leg skin angle can be used instead of the true femur-tibia shaft angle. Less knee flexion angle makes good arthroscopic view during the tibio-femoral tunneling and interference screw fixation.
