As the span of life is prolonged by socioeconomic and medical development, the percentage of the geriatric population is increasing annually. Now, surgical therapy for the geriatric patients is an important area of medicine. To understand the clinical significance of surgical geriatric patients, an analysis was made of the records at the Surgical Department of City hospital, East Seoul, for 182 patients over 65 years of age, who were treated from January 1990 through December 1995. The results are as follows: 1) The number of surgical patients admitted during the 6 years was 2,734, and the number of surgical geriatric patients admitted during the same period was 257 patients (9.4% of all surgical patients). The percentage of geriatric patients show an increasing tendency from 8.1% in 1994 to 11.3% in 1995. 2) The sex distribution was 140 male patients (54.5%) and 117 female patients (45.3%), a ratio of 1 : 0.83. 3) The average duration of admission was 18.2 days and durations of admission of less than 1 week were most common (21.8% of all geriatric admissions). 4) Of the 182 cases treated surgically, 139 cases (76.4%) involved general anesthesia, 32 cases (17.6%) anesthesia administered spinally, and 11 cases (60%) local anesthesia; One hour or less of general anesthetic time was most common (41.7%). 5) Malignant disease was found in 46 patients (25.3%); stomach cancer was the most frequently found malignant disease. Non-malignant disese was found in 136 patients (74.7%); appendicitis was the most frequently found non-malignant disease. 6) Coexistent disease was noticed in 108 patients (59.3%); cardiovascular disease was the most frequently found (27.1%), and chronic pulmonary disease (21.3%) and hypoproteinemia (14.2%) were next. 7) Operations were performed on 182 patients of the total 257 patients, operation rate of 70.8%. The old age group had a low operation rate. 8) Postoperative complications were occurred in 43 cases (23.6%), and operative mortality was 2.7%. The significant factors affecting postoperative morbidity and mortality were malignancy, long duration for the general anesthetic time, coexistent disease, and emergency operation. The results suggest that the number and the rate of surgical geriatric patients have increased and that age has little effect on the postoperative prognosis. Thus, we believe that more active preoperative treatment, complete therapy for coexistent disease, execution of elective surgery and a short anesthetic time for intentional surgery are important factors for decreasing postoperative morbidity and mortality for surgical geriatric patients.

To evaluate the intractability of partial epileptic patients by variables, the author studied 113 patients (uncontrolled: 45, controlled: 68) who were admitted to the Department of Neurology, College of Medicine, Yeungnam University from January, 1991 to August, 1993. The results were as follows. The items related to complex partial seizures, multiple seizure types and a histories of status epilepticus or clusters of seizures were significantly associated with drug-refractoriness (p<0.01). A high frequency of seizures before evaluation was associated with a poor outcome(p<0.01). The presences of known etiology of seizures, neurologic abnormalities and psychiatric disturbance were associated with limited treatment responses(p<0.01, p<0.05, p<0.01). An abnormal EEG findings such as background slowing, focal slowing, epileptiform discharges or secondarily bilateral synchrony were statistically significant (p<0.01). Age at onset, sex, distribution of epileptic foci, duration of seizure before evaluation, family history and abnormal neuroradiologic findings were not statistically significant. By these results, it was suggested that having at least four factors of the above variables were associated with limited treatment response.

It has been known that right ACA occlusions can cause callosal disconnection syndrome. A 61-year old right-handed man was admitted because of a left ACA occlusion. MRI showed infarction of the medial frontal cortex and the anterior two-thirds of the corpus callosum. He presented with weakness and gait initiation failure in the right leg with grasp reflex, suspicious alien hand sign, and tactile anomia in the right hand. He was diagnosed with transcortical motor aphasia. He was unable to successfully complete written tasks in response to dictations and writing down spontaneous answers. He wrote down incorrect words and demonstrated paragraphism with his left hand. He could copy simple items but not written words and complex items with his left hand. Finally, he had difficulties in writing answers in response to complex verbal and written commands with his left hand, but preserved the ability to simple verbal commands, somato-sensory, and visually guided tasks. We attribute these results to the anterior callosal disconnection of the right sensorimotor cortex from the left language area.

Purpose: This study sought to evaluate the clinical effectiveness of the shortening effect of the modified Weil osteotomy for the treatment of Freiberg’s disease. Materials and Methods: We reviewed 21 cases treated with the modified Weil osteotomy for Freiberg’s disease from November 2005 to June 2019. The average follow-up period was 32.5 months and the mean age of the patients was 38.3 years. The clinical results were analyzed using the American Orthopaedic Foot and Ankle Society (AOFAS) lesser metatarsophalangeal-interphalangeal scale, the visual analogue scale (VAS), and the range of motion (ROM) of the metatarsophalangeal joint. In the radiologic evaluation, the length of preoperative and postoperative metatarsal shortening was compared. Results: The average AOFAS lesser metatarsophalangeal-interphalangeal scale showed an improvement from 60.5 preoperatively to 90.9 at the latest follow-up. VAS showed a decrease from 5.4 preoperatively to 0.9 at the latest follow-up. ROM of the affected metatarsophalangeal joint increased from 40.2 degrees preoperatively to 58.6 degrees at the latest follow-up. The mean length of metatarsal shortening was 6.7 mm. There was no transfer metatarsalgia, osteonecrosis, and definite joint space narrowing. Conclusion Modified Weil osteotomy with second layer cutting is an effective treatment option to restore the joint surface and painless joint motion for patients with Freiberg’s disease.

Strumal carcinoma of the ovary is rare tumor of germ cell origin characterized by intimate mixture of thyroid tissue and carcinoid. We report a strumal carcinoid tumor associated with ipsilateral follicular cyst and contralateral mature cystic teratoma of the ovary in a 47-year-old woman. Histologically it was composed largely of trabeculae partly of insular carcinoid and focally of individual thyroid follicles. Many cells in the carcinoid areas and even some follicular areas contained abundant argyrophile granules, and they also, in the corresponding areas, demonstrated thyroglobulin. Electron microscopic findings revealed abundant neurosecretory granules and colloid material in the same cell. We agree that this tumor is derived from hybrid showing thyroid and neuroendocrine differenciation.

BACKGROUND: Determination of blood concentration is essential for the pharmacokinetic/pharmacodynamic (PK/PD) study of intravenous anesthetic agents. Knibbe's method is a rapid, simple, and reliable method to quantify propofol in low-volume samples. The aim of this study was to qualify Knibbe's method by calculating the performance error in propofol target-controlled infusion (TCI). METHODS: With ethics commitee approval and informed consent, thirty ASA 1 or 2 adult patients undergoing orthopedic surgery participated in this study. All patients were premedicated with atropine 0.5 mg IM and received general anesthesia with propofol TCI (Master TCI) supplemented by 67% N2O and 33% O2. Anesthesia was induced by propofol TCI with a target concentration of 6 microgram/ml and maintained around 3-5 microgram/ml according to bispectral index (40-50). In the middle of surgery, the target concentration was increased to 6 microgram/ml and maintained until the effect concentration matched the target concentration. Three min after equilibration, 3 ml of blood was taken from the radial artery to analyse blood concentration using HPLC with the fluorescence detection method described by Knibbe et al. Using this method, the performance error for the 1 6 microgram/ml of predicted propofol concentration in whole blood was calculated according to the following formula: measured concentration-predicted concentration/predicted concentration x 100. RESULTS: The performance errors at each concentration were -12.86, -13.61, -2.95,7.94,9.22, and 13.85% for 1-6 microgram/ml of predicted propofol concentration, respectively. CONCLUSIONS: Knibbe's method for determination of plasma propofol concentration showed itself to be accurate accuracy in that there was a relatively low performance error in the concentration range of 1 6 microgram/ml, which is considered the usual concentration range for clinical practice.

To assess the prognostic value of the 14 ECG variables obtained from the pre-discharge ECG, 35 patients were followed up for at least one year among the 80 patients of the acute myocardial infarction admitted at Seoul Paik Hospital from Sep. 1983 to Aug. 1986. The following results were obtained. 1) The overall in-hospital mortality rate was 20% and the mortality rate tended to decline year by year. 2) The one-year mortality and morbidity rate of the followed patients was 31.4%. 3) Among the 14 variables obtained from the pre-discharge ECG, T-negativity was the only statistically significant (p<0.05) one to predict the one-year prognosis in the patients after the first myocardial infarction, and we could not derive any meaningful datd from the analysis of the combined effects of the three ECG variables (PTF, ST depression and ST elevation).

Acute hyperkalemia may result from many causes, i.e. excessive load, transcellular shift, decreased renal excretion, and so on, and may be associated with irreversible and fatal cardiac manifestations, muscle weakness, ventilatory and adrenal insufficiency, etc. We experienced a case of acute hyperkalemia probably due to red cell lysis which was evident immediately after the induction of general anesthesia with thiopental sodium and succinylcholin in 1 33 year-old female patient with common bile duct obstructive jaundice. In spite of active management during anesthesia and posoperative period, eventually she died of cardiac arrest. For the successful management of the acute hyperkalemia, the anesthesiologist should be aware of its etiologies, pathophysiology, diagnosis & treatment.

Medico-legal investigations in Korea depend mostly on postmortem inspection without autopsy. Both untrained physicians and experienced forensic pathologists may not be able to determine the cause and manner of death only by postmortem inspection. The aim of our study was to show the limitations of postmortem inspection by evaluating the discrepancy between the results of postmortem inspection and autopsy after natural death. The manner of death by postmortem inspection changed to unnatural death in 9.4% of the cases (12 cases/127 cases) after autopsy. The cause of death in most cases was consumption of alcohol, agricultural chemicals, and antipsychotic intoxication. The cause of death by postmortem inspection changed in 24.3% of the cases (26 cases/107 cases) among cases of confirmed natural death after autopsy. The positive predictive value of cause of death by postmortem inspection was higher for cardiovascular disease (79.0%) and lower for chronic alcoholism and/or chronic liver disease (28.6%). This study shows that forensic pathologists could make considerable errors in determining the cause and manner of death without autopsy and emphasizes the necessity to refine medico-legal investigations in Korea by introducing the limited autopsy with toxicologic study and supportive postmortem imaging.

In the present study, immunohistochemical detection of p53 oncoprotein was performed to determine whether the grade of differentiation and the histologic type of gastric adenocarcinoma, and the degree of atypia accompanied with adenoma can be related to p53 mutation. Paraffin sections of 22 gastric adenomas and 56 gastric adenocarcinomas were examined for the overexpression of p53 oncoprotein with the avidin-biotin peroxidase complex staining procedure. The obtained results were as follows; 1. All the 22 cases of adenomas and 16 cases of well differentated adenocarcinomas showed uniformly negative staining. 2.Seven of 18 cases of moderately differentiated adenocarcinomas(39%), and five of 30 cases of poorly differentiated adenocarcinomas(17%) exhibited p53 protein expression. 3. Three of 29 cases of diffuse type (10%) and 9 of 19 cases of intestinal type(47%) exhibited p53 protein expression. These results suggest that p53 mutation is important in carcinogenesis of the intestinal type of gastric adenocarcinoma, and there is no correlation between the differentiation of gastric adenocarcinoma and the degree of p53 oncoprotein overexpression.
