Fractures of the patella are intra-articular fractures of a sesamoid bone. The goal of treatment is to restore the function of the extensor mechanism and congtvity of the articular surface of the knee. So postoperative traumatic arthritis is minimized by an accurate reduction of the articular surfaces. We analyzed nine cases of the patella fractures which were treated by the use of arthroscopy to allow visualization of and working inside of joints, and the use of the image-intensifier fluoroscope to allow real-time vi.sualization of the skeleton. The results were as follows The fixation of patelia fractures using an arthroscopy could be applied to transverse or vertical fractures without comminution and severe osteoporosis. 2. In the treatment of two types of patella fractures (simple transverse e rnarginal vertical fractures without comminution), clinically satisfactory results were obtained through the accurate reduction of articular surface using an arthroscopy and image intensifier.

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.

Pseudoaneurysm of splenic artery may arise from a vascular erosion by the inflammatory processes around the splenic artery, particularly in acute pancreatitis and chronic pancreatitis, which may cause rupture of pseudoaneurysm and life threatening hemorrhage. Collective experience with this massive hemorrhage is attended by a high mortality rate even with prompt therapy, and conservative management is associated with an almost 100 per cent of mortality rate. Identification of the bleeding site at laparotomy may be exceedingly difficult, which makes the preoperative detection of bleeding source desirable. Peripancreatic vascular lesions can be identified by angiography, and in selected cases the risk of urgent operation to control massive hemorrhage may be obviated by embolization. The authors have recently experienced a case of ruptured splenic artery pseudoaneurysm combined with a pancreatic pseudocyst in a 6 years old boy. A bolus enhanced CT scan and angiography were essential to confirm these complications of pancreatic pseudocyst. We managed this child successfully with an urgent procedure of transcatheter arterial embolization and another elective surgery of pancreatic pseudocyst.

PURPOSE: The purpose of this study was to explore the relationships of family strain, perceived social support, family hardiness, and family adaptation and identify the family resiliency factors for the adaptation of families who have a child with congenital heart disease. METHOD: The sample consisted of 90 families who had a child diagnosed with congenital heart disease and completed surgical treatment. Data was collected from parents using a questionnaire. RESULTS: Results from path analyses revealed that family strain had a direct effect on both perceived social support and family hardiness, and an indirect effect on family adaptation. Also, the findings revealed that perceived social support had a direct effect on both family hardiness and family adaptation, and family hardiness had a direct effect on family adaptation. Thus, these results indicated that perceived social support and family hardiness had a mediating effect on family strain. CONCLUSION: Findings provide the evidence for the theoretical and empirical significance of perceived social support and family hardiness as family resiliency factors for family adaptation. Clinical implications of these findings might be discussed in terms of family-centered nursing interventions for the families who have a child with congenital heart disease based on an understanding of family resiliency for adaptation.

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.

Families of children with cancer face many illness-related demands. The perceived social support is a critical resource for the family adaptation process. And the patterns of family adaptation to childhood cancer varies as characteristics of disease, which is prognosis, the influence of cognition function, and treatment process. The conceptual definition of social support is not unidimensional. However, most studies focus on general aspect of mediating effects on adaptation. Diverse dimensions of perceived social support should be considered in its effectiveness for intervention. Therefore, this study was undertaken to determine whether family's perceived social support influences the family adaptation of family with pediatric cancer and what dimension influences mostly in family adaptation as the characteristics of disease in the family of children with cancer. The subject was consisted of 102 families with pediatric cancer who had been diagnosed as leukemia or brain tumor last 2 years. Those families had participated in the education program or meetings for family who have with pediatric cancer children. The measurement for this study were Personal Resource Questionnaire (PRQ) Part- ll developed by Brandt and Weinert to measure parents' perceived social support, and the McCubbin's Coping Health Inventory for Parents (CHIP) to measure family coping. The results of this study can be summarized as follows; Regression analysis showed that perceived social support has effect on family adaptation with beta=.43, p < .01. In the group of family of child with leukemia, social support as general has effect on adaptation (beta=.40, p < .01) and specially, social support perceived as intimacy was strongly effect on family adaptation. And In the group of brain tumor, Social support has effect on adaptation(beta=.46, p < .01) and among the social support domains, the self esteem dimension was most predictable to family adaptation. In conclusion, the perceived social support is a predictor on family adaptation and useful vehicle to help family who has child with pediatric cancer. An important clinical implication is that specified support program for intervention may be useful and critical for the family who has diverse pediatric conditions of childhood cancer. Further studies should stress the effects of family support for clinical intervention and is needed with diverse stage of development and pediatric conditions.

We present a study on hospital stay in 1000 consecutive head injuries. The mean hospital stay and standard deviation were calculated in a given condition according to some variables, such as sex, age, Glasgow Coma Score on admission, skull fracture, CT findings, and treatment. Usually, standard deviation was greater than the mean value in a given condition and hospital stay varied in a wide range, representing that the duration of treatment is related not only to the severity but also various individual properties. Since the associated injuries were variable in location, type and severity, they altered hospital stay greatly. Thus hospital stay was analyzed in patients without associated injuries. Hospital stay was largely dependant on three variables. Low Glasgow Coma Score on admission, presence of intracranial mass lesion or diffuse axonal injury, and operative treatment prolonged hospital stay. Skull fracture also lengthened hospital stay but only in patients without associated injuries. Duration of treatment should be recorded in all medical certificates related to the injury. For the proper estimation of duration of treatment, more reports are needed in this field.

The prognosis of advanced non-small cell lung cancer (NSCLC) is very poor and the median overall survival is 10 to 12 months, despite the use of chemotherapy and targeted therapy. Recently, many targeted agents for NSCLC have been developed and tested in clinical trials. Of these, chemotherapeutic agents targeting epidermal growth factor receptor (EGFR), such as gefitinib, erlotinib and cetuximab, have been very efficacious in the treatment of NSCLC. Many phase III trials have evaluated the efficacy of these agents in combination with cytotoxic chemotherapy. Based on the results of these trials, clinical and molecular predictors of the response to EGFR-targeted agents, such as EGFR mutations or gene amplification, have been elucidated. Recent advances in understanding the biologic basis of acquired resistance to these agents have potential to improve the clinical effectiveness of agents targeting EGFR. Another agent, bevacizumab, targets an angiogenesis inhibitor, and has improved the survival in advanced NSCLC when used in combination with chemotherapy. In addition, many agents targeting tyrosine kinase inhibitors are being used in clinical trials. This review summarizes the outcomes of clinical trials evaluating agents targeting EGFR, angiogenesis inhibitors, and other molecules used alone or in combination with chemotherapy for the treatment of advanced NSCLC. Also, the predictive role of NSCLC histology for chemotherapy response will be summarized from the results of phase III studies.
