Recently, with the remarkable theoretical progress made in anesthesiology these years, reports are being made on the results of the study on the complications, minor or major, caused by previous general anesthesia. However, .the reports on incidence vary according to the reporters. According to Riding, the recent development of anesthesiology, anesthetic inatruments, knowledge of physiology, anesthetics, induction agents and muscle relaxants are said to have reduced the incidence of complications to a great extent. Riding, Gold and Dyrberg report that the factors capable of influencing the incidence of complication, in the post-operative period include age, sex, premedicants for anesthetics, inhalation method of anesthetics, time of anesthesia, muscle relaxant, use of induction agent, acid-base imbalance and developed knowledge of physioloy, operation site, mental state of patients before operation, general condition, anesthetic technique, and. adequate selection of medicine. Working for Department of Anesthesiology, Hanyang University, from October 1976 to August 1977, we selected, out of the patients who received general anesthesia, 523 males and 372 females, totalling 895, who showed no abnormal symptoms in their respiratory systems, circulatory systems and metabolic systems and observed the incidence of complication in the light of sex, age and operation site, the factors supposed to affect the incidence. An hour prior to the general anesthesia, the patients were given intramuscular injection with premedicants atropine 0. 01 mg per kg, Valium 0. 2 mg or Demerol 1 mg per kg of body weight. For induction of anesthesia, Epontol 10 mg per kg and succinylcholine 1 mg per kg of body weight were injected in the veins, then ventilation was made for a minute with mask and then endotracheal tubes were inserted. and then a minimum amount of air was injected. into the cuff of the endotracheal tube, and the ventilation was done in a semi-closed system. During the period of maintenance, anesthesia was administered in a semi-closed system with 0. 5~l. 0% halothane, 3 L/min of nitrous oxide, 2 L/min of oxygen; and if need be, muscle relaxant was injected into the vein. In case a nondenolarizing agent was used in the course of maintenance, atropine 0. 5~1. 0 mg and neostigmine 2.0 ~ 4.0 mg were injected into the vein for reversion at the recovery time. After the patient was completely recovered, the endotracheal tube was cautiously removed, so as not to give trauma to the throat. As for method of observations, 24 hours after the patient had recovered, we visited the patient in the ward, first observing the existence or nonexistence of incidence of minor complications, and then calculating the incidence by the distribution of sex, age and operation site. The outcome of the observation of the above results by statistics and by chi square test is as follows; 1) the incidence of complications after general anesthesia was high in females. 2) Age has not affected the incidence of complications. 3) The incidence of nausea was highest in the patients with abdominal operation. 4) The incidence of sore throat was highest in the head and neck patients. 5) The incidence of fever was highest in the abdomen patients. 6) The incidence of headache was highest in the head and neck patients.

Double primary cancer is defined as the case of primary malignant tumors, which must be arise in different sites and have a different histologic appearences. The number of reported cases of double primary malignant tumors has increased in recent and the occurrence of multiple primary cancers in the same individuals is one of the interesting subjects for investigation and research in relation to the carcinogenic mechanism and/or genetic factors. We have experienced a case with double primary malignant tumors of different site origins such as stomach adenocarcinoma and rectal adenocarcinoma, which were diagnosed by biopsies with gastro and colono fiberscopy. For its great rarity, we report this case with review of literatures.

PURPOSE: Goggles are frequently worn in the sport of swimming and are designed to form a seal around the periorbital tissue orbit. The resultant pressure on the eye may have the potential to affect intraocular pressure and blood flow of the optic nerve head. This study evaluates the influence of wearing swimming goggles on intraocular pressure (IOP) and blood flow of the ocular nerve head (ONH) in normal subjects. MATERIALS AND METHODS: Thirty healthy participants took part in this study. The IOP of each participant was measured using a Goldmann tonometer. Measurements were taken immediately before putting on swimming goggles, at 5, 10, 30, and 60 minutes after putting on swimming goggles, and then immediately after taking off the goggles. Blood flow of the ONH was measured using the Heidelberg retinal flowmeter. RESULTS: The average IOP before, during and after wearing the swimming goggles were 11.88 +/- 2.82mmHg, 14.20 +/- 2.81 mmHg and 11.78 +/- 2.89mmHg, respectively. The IOP increased immediately after putting on the goggles (p < 0.05) and then returned to normal values immediately after removal (p > 0.05). Blood flow of the ONH was 336.60 +/- 89.07 Arbitrary Units (AU) before and 319.18 +/- 96.02 AU after the goggles were worn (p < 0.05). CONCLUSION: A small but significant IOP elevation was observed immediately after the swimming goggles were put on. This elevated IOP was maintained while the goggles were kept on, and then returned to normal levels as soon as they were taken off. Blood flow of the ONH did not change significantly throughout the experiment. These facts should be considered for safety concerns, especially in advanced glaucoma patients.

PURPOSE: To assess the midterm results of the hydroxyapatite hip system with acetabular cups, with particular emphasis upon cup wear and loosening, using a computer assisted-3 dimensional technique. MATERIALS AND METHODS: From March 1992 to December 1996, 52 patients (61 hips) were available for inclusion in this study after an average duration of follow up of 6 years and 4 months. Clinical evaluation was performed using the Harris hip scoring system. Initial postoperative and long term follow up films were digitized, and 2 dimensional linear and 3 dimensional wear was measured by using a computer assisted-3 dimensional technique. Acetabular bone changes are described using previous published methods. RESULTS: An analysis of the clinical results showed a mean Harris hip score of 47.2 points preoperatively and 89.8 points at the final visit. The mean polyethylene 3D-linear wear rate was 0.26 mm/year and mean volumetric wear rate was 105.9 mm3/year. In 16 hips (26.2%) the linear wear rate was more than 0.3 mm/year (0.30-0.74 mm/year). Osteolytic changes of the acetabulum were recorded in 51% around acetabular cups, in which considerable wear of the acetabular polyethylene was evident by the five-year radiographic findings. CONCLUSION: Midterm results of hydroxyapatite coated acetabular cups were disappointing in terms of acetabular cup and liner wear, despite early accelerated bone remodeling by hydroxyapatite and excellent early clinical results.

Anhidrotic ectodermal dysplasia is inherited as an X linked recessive trait. This disor der is characterized by hypotrichosis, hypodontia and hypohidrosis. The diagnosis is often delayed until the first or second year of life, after repeated episodes of potentially damaging high fever. In the newborn period, the diagnosis is more difficult, but early diagnosis is of importance in ensuring that the appropriate enivironment and medical measures be taken to avoid uncontrolled hyperthermia. We have experienced a case of anhidrotic ectoclermal dysplasia in an8-day-old male patient who showed charecteristic features including hypotrichosis, peeling or scaling of the skin, recurrent fever and a characteristic face. A skin biopsy from the right palm revealed no sweat gland strutures. A brief rview with related literature is also presented.

In recent years, there has been renewed interest in preoperative methods to reduce gastric acidity, thus lessening the risk of a serious pulmonary reactions following aspiration of gastric contents. Emergency obstetrical patients frequently have large volumes of gastric fluid. It is less commonly appreciated that patients fasting prior to elective surgery afterive in operating room with large gastric fluid volumes with a low pH. Prophylactic preoperative oral administration of antacids has been shown to reduce preoperative gastric acidity in significant percentage of patients, but aspiration of antacids can be associated with pulmonary complications, and there use may be associated with increased gastric volume. Preoperative adrpinistration of glycopyrrolate may decrease the frequency of surgical patients with a low gastric pH, and it appears that the volume of gastric fluid may be reduced by medication that relax the pylorus. However, none of these pharmacologic manuevers completely abolisbes the possibility of serious pulmonary damage with aspiration. Mendelson and Teabeat demonstrated the importance of pH in the etiology of acid aspiration and it is generally accepted that the critical pH is 2. 5 or less, i.e. the risk of aerious pulmonary reaction increases progressively as the pH of the aspirate falls below 2.5. A critical volume of acid aspirate is also necessary for widespread pulmonary damage to occur irrespective of a low gastric pH. The critical volume is rhesus monkeys has been shown to be 0.4 ml/kg, but the critical volume in man is less well difined. Several investigators have determined the patient to be at risk of serious pulmonary complications with aspiration if at least 25 ml of gastric fluid with a pH of 2.5 or less is aspirated. The present study was undertaken to investigate the effects on the volume and pH of gastric juice under general anesthesia. The 35 patients were studied, and were divided. into 4 group account to the kind of premedicants, N.P.O. time, weight, and obstetric patients Gastric juice, aspirated through a Levine tube, was examined for pH and. volume under general anesthesia.

Spontaneous rupture of the renal pelvis or ureteropelvic juction area with extravasation of urine into the perinephric space is an uncommon pathologic condition (1). We report a case of 72-year-old woman who suffered 2 days of left loin pain. The patient has got residual urine sensation and weak urine stream since she has gone through a radical hysterectomy 17 years before. Because of these symptoms of voiding difficulty, the patient had abdominal straining during her urination. A CT scan exhibited renal pelvis rupture with perirenal extravasation of urine due to severe hydronephrosis, that was exacerbated by hidden neurogenic bladder disease. Moreover, the patient has detrusor underactivity and high intravesical pressure at voiding trial in the urodynamic study. One month after the percutaneous nephrostomy insertion into the left renal pelvis, the patient was successfully treated. The size of renal pelvis decreased. Moreover, urinoma disappeared in follow up CT scan image.

OBJECTIVE: To evaluate the differences in maxillomandibular transverse measurements at either the crown or the estimated center of resistance (CR), and to compare values between normal occlusion and Class III malocclusion groups. METHODS: Dental casts and computed tomography (CT) data from 30 individuals with normal occlusion and 30 with skeletal Class III malocclusions were evaluated. Using the casts, dental arch widths (DAWs) were measured from the cusp tips, and basal arch widths (BAWs-cast) were measured as the distance between the points at the mucogingival junction adjacent to the respective cusp tips. The BAWs determined from CT (BAWs-CT) images were measured from the estimated CRs of the teeth. RESULTS: None of the DAW measurements or maxillomandibular DAW differences showed statistically significant intergroup differences. In contrast, the maxillary BAWs-CT and BAWs-cast were lesser in the Class III malocclusion group than in the normal occlusion group. The mandibular BAWs-CT were significantly greater in the Class III malocclusion group than in the normal occlusion group. Moreover, the maxillomandibular BAW differences on both CT and cast showed significant intergroup differences in all transverse measurements. CONCLUSIONS: The maxillomandibular DAW differences showed no significant intergroup differences. In contrast, the maxillomandibular BAW differences on both CT and cast showed significant intergroup differences in all transverse measurements. The maxillomandibular BAW differences at the estimated CRs, measured using CT or casts, can reveal underlying transverse maxillary basal arch deficiencies in patients with skeletal Class III malocclusions.

Background:
Postmenopausal status increases the risk of cardiovascular disease, and C-reactive protein (CRP) constitutes an independent cardiovascular risk factor. This study aimed to investigate the factors associated with increased high-sensitivity CRP (hs-CRP) level in postmenopausal women.
Methods:
We included postmenopausal women without laboratory test results that suggested acute inflammation who participated in the Korea National Health and Nutrition Examination Survey between 2016 and 2017. The participants were divided into high and low hs-CRP groups (cutoff value, 3.0 mg/L). We investigated factors that influenced the hs-CRP level with logistic regression analysis.
Results:
The total number of subjects was 2,739, of whom 76.4% had low hs-CRP levels and 23.6% had high hs-CRP levels. The mean age and body mass index were higher in the high than in the low hs-CRP group. In the simple logistic regression analysis, high hs-CRP level was associated with smoking, whereas low hs-CRP level was associated with aerobic exercise, use of oral contraceptives, and history of pregnancy in postmenopausal women. When the analysis was adjusted for confounding variables, histories of smoking and pregnancy had a statistically significant association with high hs-CRP level.
Conclusion
This study showed that the important modifiable risk factors of elevated hs-CRP level in postmenopausal women of Korea include obesity, smoking, and lack of aerobic exercise, but well-controlled prospective investigations should be considered.

An intraluminal duodenal diverticulum (IDD) is a rare congenital anomaly consisted of a sac-like mucosal projection within the second portion of the duodenum. Even though most of cases are asymptomatic, patients may develop recurrent abdominal pain, pancreatitis, and gastrointestinal bleeding. We report a case of symptomatic IDD which presented as acute pancreatitis and obscure gastrointestinal bleeding. Diagnosis was made by typical findings of upper GI series and coronal reformatted CT images. Although surgical resection is the treatment of choice, endoscopic incision and ligation with detachable snare was performed which led to a good result.
