A Case of Pai Syndrome: First Reported Case in Korea / 대한주산의학회잡지

Pai syndrome is a rare disorder, first described in 1987. Diagnostic criteria are the presence of the nasal polyp and one of the following: midline cleft lip, congenital polyp of mid-anterior alveolar process, and pericallosal lipoma. Thirty-six cases of Pai syndrome have been described so far. We report 1 case of Pai syndrome accompanied by congenital nasal polyp and callosal lipoma with partial agenesis of corpus callosum, the first time in Korea.

Sacral Cutaneous Clues to Underlying Spinal Abnormalities

PURPOSE: Sacral cutaneous lesions in newborns are associated with numerous spinal abnormalities. Early detection is important, because spinal abnormalities may cause neurological symptoms. Radiologic screening tests have been performed on newborns with sacral cutaneous lesions. This study aimed to substantiate the associations between sacral cutaneous lesions and spinal abnormalities. METHODS: From January 2007 until November 2013, we retrospectively reviewed the charts of 743 newborns with sacral cutaneous lesions that included sacral dimples, which were deeper than 5 mm and situated further than 2.5 cm from the anus, deviated gluteal furrow, hairy patch, hemangioma, dyspigmentaion, and the presence of mass, and skin tag. RESULTS: 743 newborns with sacral cutaneous lesions were examined, including 24 newborns with abnormal ultrasonographic images. Tethered cord which affected 18 (2.4%) of the newborns, was the most commonly found spinal abnormaility. Of these 9 newborns had other spinal abnormalities in addition to tethered cord including lipoma, cyst, spina bifida occulta, lipomyelomeningocele, and dermal sinus tract, and 9 newborns had isolated tethered cord only. Other spinal abnormalities found included isolated lipoma (3 newborns, 0.4%), and subarachnoid cyst (2 newborns, 0.3%), and of the 2 newborns (0.3%) who had dermal sinus tract, 1 also had a lipoma and the other also had a tethered cord. Normal variants included coccygeal pit (43 newborns, 5.8%), and ventriculus terminalis (10 newborns, 1.4%). Of the 646 newborns with isolated sacral cutaneous lesion, 11 (1.7%) had abnormal ultrasonographic images, and of the 97 newborns with combined sacral cutaneous lesions, 13 (13.4%) had abnormal ultrasonograpic images. CONCLUSION: Sacral cutaneous lesions in newborns can be associated with spinal abnormalities, and the strongest marker of spinal abnormality is a combined lesion. Therefore, ultrasonography should be performed on newborns who present with sacral cutaneous lesions to detect and investigate any underlying spinal abnormalities.

Health Beliefs, Self-efficacy and Medical Care Utilization of Korean Nurses / 산업간호학회지

PURPOSE: It was to identify the relationship with the health beliefs, self-efficacy and medical care utilization in nurses in order to provide basic data for program development to actively help nurses' health practice. METHODS: The subjects were 360 hospital nurses in P city, K Province. Instruments were health belief developed by Walker, Sechrist & Pender (1987), self-efficacy by Sherer, Maddux & Mercandante(1982), and medical care utilization by Korean National Health & Nutrition Examination Survey(2006). The data were analyzed as descriptive statistics, Chi-square, t-test, and ANOVA using SPSS 11.5. RESULTS: There were significant differences in medical care utilization depending on age(p=.008), marital status(p=.019), education level(p=.005), types of work(p=.017), nursing units(p=.018), and period of work(p=.001). Use of outpatient clinic was significantly different depending on perceived susceptibility(F=2.463, p=.045). Nurses who consulted to doctor in other hospital had higher perceived severity(F=2.759, p=.028). Nurses who used complementary medicine had higher perceived barrier(F=2.278, p=.047). The score of self-efficacy was significantly different in medical care service frequency (F=3.030, p=.018) and to whom their health problems consulted(F=3.092, p=.010). CONCLUSION: Medical service utilization was different depending on the demographic characteristics, perceived susceptibility, severity, and barrier, and self efficacy. It is needed to give health promotion program considering these factors for nurses.

The Recent Outcomes after Repair of Tetralogy of Fallot Associated with Pulmonary Atresia and Major Aortopulmonary Collateral Arteries / 대한흉부외과학회지

BACKGROUND: Tetralogy of Fallot (TOF) with pulmonary atresia and major aortopulmonary collateral arteries (MAPCAs) is complex lesion with marked heterogeneity of pulmonary blood supply and arborization anomalies. Patients with TOF with PA and MAPCAs have traditionally required multiple staged unifocalization of pulmonary blood supply before undergoing complete repair. In this report, we describe recent change of strategy and the results in our institution. MATERIAL AND METHOD: We established surgical stratagies: early correction, central mediastinal approach, initial RV-PA conduit interposition, and aggressive intervention. Between July 1998 and August 2004, 23 patients were surgically treated at our institution. We divided them into 3 groups by initial operation method; group I: one stage total correction, group II: RV-PA conduit and unifocalization, group III: RV-PA conduit interposition only. RESULT: Mean ages at initial operation in each group were 13.9+/-16.0 months (group I), 10.4+/-15.6 months (group II), and 7.9+/-7.7 months (group III). True pulmonary arteries were not present in 1 patient and the pulmonary arteries were confluent in 22 patients. The balloon angioplasty was done in average 1.3 times (range: 1~6). There were 4 early deaths relating initial operation, and 1 late death due to incracranial hemorrhage after definitive repair. The operative mortalities of initial procedures in each group were 25.0% (1/4: group I), 20.0% (2/10: group II), and 12.2% (1/9: group III). The causes of operative mortality were hypoxia (2), low cardiac output (1) and sudden cardiac arrest (1). Definitive repair rates in each group were 75% (3/4) in group I, 20% (2/10, fenestration: 2) in group II, and 55.6% (5/9, fenestration: 1) in group III. CONCLUSION: In patients of TOF with PA and MAPCAs, RV-PA connection as a initial procedure could be performed with relatively low risk, and high rate of definitive repair can be obtained in the help of balloon pulmonary angioplasty. One stage RV-PA connection and unifocalization appeared to be successful in selected patients.

Endoventricular Circular Patch Plasty (Dor Procedure) for Ischemic Left Ventricular Dysfunction / 대한흉부외과학회지

Background: We evaluated the efficacy of Dor procedure in patients with ischemic left ventricular dysfunction. Material and Method: Between April 1998 and December 2002, 45 patients underwent the Dor procedure concomitant with coronary artery bypass grafting (CABG). Left ventricular ejection fraction (LVEF) and left ventricular end-diastolic/end-systolic volumes (LVEDV/LVESV) were measured by echocardiography, myocardial SPECT, and cardiac catheterization and angiography performed at the sequence of preoperative, early postoperative, and one year postoperative stage. Result: Cardiopulmonary bypass and aortic clamp times were mean 141+/-64, 69+/-24 minutes, respectively. Intraaortic balloon pump (IABP) therapy was required in 19 patients (42%; 7 preoperatively, 9 intraoperatively, 3 postoperatively). Operative mortality rate was 2.2% (1/45). Postoperative morbidities were low cardiac output syndrome (12), atrial fibrillation (5), acute renal failure (4), and postoperative bleeding (4). Functional class (NYHA) was improved from classes 2.8 to 1.1 (p<0.01). When we compared between the preoperative and early postoperative values, LVEF was improved from 32+/-9% to 52+/-11% (p<0.01). The asynergy portion decreased from 57+/-12% to 22+/-9%, and LVEDV/LVESV indexes improved from 125+/-39 mL/m2, 85+/-30mL/m2 to 66+/-23 mL/m2, 32+/-16 mL/m2 (p<0.01). Although these changes in volumes were relatively preserved at postoperative one year, the left ventricular volumes showed a tendency to increase. Conclusion: After the Dor procedure for ischemic left ventricular dysfunction, LVEF improvement and left ventricular volume reduction were maintained till postoperative one year. The tendency for left ventricular volume to increase at postoperative one year suggested the requirement of strict medical management.

Surgical Treatment of Complications after Fontan Operation / 대한흉부외과학회지

BACKGROUND: The Fontan operation has undergone a number of major modifications and clinical results have been improving over time. Nevertheless, during the follow-up period, life-threatening complications develop and affect the long-term outcomes. Surgical interventions for these complications are needed and are increasing. MATERIAL AND METHOD: From April 1988 to January 2000, 16 patients underwent reoperations for complications after Fontan operation. The mean age at reoperation was 8.8+/-5.5 years. Initial Fontan operations were atriopulmonary connections in 8 and total cavopulmonary connections in 8. Total cavopulmonary connections were accomplished with intracardiac lateral tunnel in 5 and extracardiac epicardial lateral tunnel in 3. Five patients had variable sized fenestrations. The reasons for reoperations included residual shunt in 6, pulmonary venous obstruction in 3, atrial flutter in 3, atrioventricular valve regurgitation in 2, Fontan pathway stenosis in 1, and protein-losing enteropathy in 1. RESULT: There were 3 early and late deaths respectively. Patients who had residual shunts underwent primary closure of shunt site (n=2), atrial reseptation for separation between systemic and pulmonary vein (n=2), conversion to lateral tunnel (n=1), and conversion to one and a half ventricular repair (n=1). Four patients who had stenotic lesion of pulmonary vein or Fontan pathway underwent widening of the lesion (n=3) and left pneumonectomy (n=1). In cases of atrial flutter, conversion to lateral tunnel after revision of atriopulmonary connections was performed (n=3). For the atrioventricular valve regurgitation (n=2), we performed a replacement with mechanical valve. In one patient who had developed protein-losing enteropathy, aorto-pulmonary collateral arteries were obliterated via thoracotomy. Cryoablation was performed concomitantly in 4 patients as an additional treatment modality of atrial arrhythmia. CONCLUSION: Complications after Fontan operation are difficult to manage and have a considerable morbidity and mortality. However,more accurate understanding of Fontan physiology and technical advancement increased the possibility of treatment for such complications as well as Fontan operation itself. Appropriate surgical treatment for these patients relieved the symptoms and improved the functional class,Although the results were not satisfactory enough in all patients.

Carcinoid tumor located in the parietal pleura / 대한흉부외과학회지

Pulmonary carcinoid tumors are thought to originate from neuroendocrine Kulchitsky's cells in the bronchial epithelium. The majority of typical carcinoid tumors are located centrally. However, atypical carcinoids are frequently situated peripherally and display malignant histologic features with aggressive behavior. Few reports are discribing carcinoid tumors originating from the pleura. We report a typical carcinoid tumor located mainly in the parietal pleura invading the chest wall without evidence of pulmonary parenchymal invasion.

The Role of Bone Scans in Routine Preoperative Evaluations of Non-Small Cell Lung Cancer Patients / 대한흉부외과학회지

BACKGROUND: The objective of this study was to assess the usefulness of bone scans in routine preoperative examinations of patients with newly diagnosed non-small cell lung carcinoma. MATERIAL AND METHOD: We reviewed the medical records of 258 patients who were newly diagnosed with non-small cell lung cancer in our hospital between January 2000 and December 2000. More than half of the patients (132) were deemed to be inoperable due to their advanced stage based on the CT scans. The remaining 126 patients were considered potentially operable. For these patients, clinical evaluation including the presence of bone pain, serum alkaline phosphatase, and calcium levels was used as clinical predictors of bone metastasis. All patients received bone scans. Bone X-rays, MRI or bone biopsy were performed to confirm the presence of bone metastasis. The usefulness of the bone scan was evaluated by comparing its power of predicting bone metastasis to that of the clinical information. RESULT: In all patients, the positive and negative predictive values of bone scans for the bone metastasis were 44%, and 99%, respectively. Those of the clinical information were 38% , and 94%. However, in potentially operable patients, the negative predictive value of the clinical information was as high as 99%. CONCLUSION: If newly diagnosed non-small cell lung cancer patients are presented as potentially operable on the basis of CT scan with no clinical evidence of distant metastases, curative resection could be considered without performing routine bone scans because of the low probability of bone metastasis. However, if there are positive clinical findings, further evaluations, including bone scan should be followed as metastasis will be documented in more than 30% of patients.
