Inguinal hernia is one of the most common surgical diseases in pediatric patients. But the management of the side opposite the clinically apparent inguinal hernia, the "silent side" is controversial. Four hundred fifty-eight cases of pediatric inguinal hernias, operated by one pediatric surgeon at the Divisionof Pediatric Surgery, Department of Surgery, Chonbuk National University Hospital from January 1998 to December 2002, were reviewed retrospectively to determine the characteristics and significances of the silk-glove test on the side opposite the clinically apparent inguinal hernia. Males were preponderant as 2.8:1. Allhernias were of the indirect type and were repaired by high ligation of the sac. There were 238 (52.0 %) right sided hernias, 160 (35.0 %) were on the left and 60 (13.0%) were bilateral. The number of patients with a positive silk-glove sign on the contralateral side was 158(39.7 %), and 133 of these had a contralateral patent processus vaginalis. Positive predictive value of Silk-glove test was 84.2 % (133/158). The silk-glove test is a simple, safe, and relatively accurate method for contralateral exploration in the unilateral inguinal hernias in children.

The purpose of this paper is to prove the following results; (1) Let R be a prime ring of char $(R)\neq 2$ and I a nonzero left ideal of R. The existence of a nonzero symmetric bi-derivation D : $R\timesR\;\longrightarrow\;$ such that d is sew-commuting on I where d is the trace of D forces R to be commutative (2) Let m and n be integers with $m\;\neq\;0.\;or\;n\neq\;0$. Let R be a noncommutative prime ring of char$ (R))\neq \; 2-1\; p_1 \;n_1$ where p is a prime number which is a divisor of m, and I a nonzero two-sided ideal of R. Let $D_1$ ; $R\;\times\;R\;\longrightarrow\;and\;$ $D_2\;:\;R\;\times\;R\;longrightarrow\;R$ be symmetric bi-derivations. Suppose further that there exists a symmetric bi-additive mapping B ; $R\;\times\;R\;\longrightarrow\;and\;$ such that $md_1(\chi)\chi ＋ n\chi d_2(\chi)=f(\chi$) holds for all $\chi$$\in$I, where $d_1 \;and\; d_2$ are the traces of $D_1 \;and\; D_2$ respectively and f is the trace of B. Then we have $D_1=0 \;and\; D_2=0$.

본 환축은 안구진탕, 좌측 편측보행을 주증으로 내원하여 MRI 검사 및 조직병리학적 검사로 수막종으로 진단 하였다. 초기에 prednisolone과 hydroxyyrea를 투약하였으나 증상의 악화로 중단하였으며, 이후 lomustine 화학요법을 실시하여 임상 증상이 개선되어 유지해오다가 증상이 발현 된지 18개월째에 자연사한 증례이다.

This is a report on four cases of atelectasis which were implicated as one case of mucoid impaction and three cases of blood clots in main bronchus. The 1st case was found to be massive atelectasis on Lt. entire lung due to mucoid impaction with pulmonary tuberculosis. This case was performed the Lt. pneumonectomy. There are contain-ing impacted yellowish-gray jelly like thick materials on the Lt. whole bronchial trees and pathologic findings were consistent with tuberculosis including caseation necrosis and multinucleated giant cell on whole left lung thoroughly in microscopic findings. The 2nd and 3rd case [25 years old female and 30 years old female] were diagnosed as one sided entire lung ateletasis which were led by accumulation of old blood clots on bronchus following incomplete expectoration of sudden massive hemoptysis from pulmonary tuberculosis lesion. These two cases were recovered by removal of blood clots and bronchial irrigation under bronchoscopy. Follow up chest film revealed well aeration. The 4th case [45 years old] was taken the removal of old blood clots and tissue debris under the bronchoscopy as bronchial obstruction following massive hemoptysis. The cytologic findings revealed the class III in fresh sputum and class 1V in bronchial irrigation which may suggest of malignancy. However, we could not found the causative lesions suggestive malignancy by the bronchography and other diagnostic measurements.

동성애로 인하여 인간면역결핍 바이러스에 감염된 54세 남자가 발열, 우측흉통을 주소로 응급실로 내원하였다. 흉부단순촬영상 우측 흉막삼출액이 관찰되어 폐쇄식 흉관삽입술을 시행하였으며 흉막액 세균배양검사에서 살모넬라와 대장균이 동정되었고 항생제 투여에도 불구하고 증상 호전이 없어 늑막전폐절제술을 시행하였다. 수술 후에 환자상태는 호전되는 양상이었으나 수술 후 10일째 부분발작을 보여 뇌 단층촬영을 시행하였으며 우측 전두엽과 좌측 전측두엽에 여러 개의 종괴가 관찰되었고 수술 후 12일째 의식이 저하되면서 급성 호흡부전으로 수술 후 14일째 사망하였다.

우폐하엽의 폐암이 심낭과 좌심방의 하폐정맥 유입구를 침범한 62세 남자 환자에서 심폐체외순환을 이용하여 우폐 중하엽절제술을 시행하였다. 환자는 수술 후 제2일째에 우폐상엽의 국한성 폐부종이 발생하였으며 폐부종이 치료된 후 우폐의 기관지늑막루가 발생하였다. 유경대망을 이용하여 기관지 늑막루를 봉합하였다. 그 후의 임상 경과는 양호하였으며 환자는 현재 6년째 재발 없이 건강히 지내고 있다.

Congenital dilatation of the common bile duct (choledochal cyst) is an uncommon disease. Although the etiology is unknown yet, various theories such as distal obstruction of the common bile duct, congenital weakness of the duct and anomalous union of the pancreaticobiliary duct have been offered to explain the occurrence of choledochal cyst. Thirty - six cases of choledochal cyst over 22 years were analyzed clinically and classified according to Todani's classification and Kimura's anomalous union of pancreaticobiliary duct type. Todani type 1 consisted with 22 cases which were subdivided into 19 cases of type Ia, 1 case of type Ib and 2 of type Ic. Type IVa consisted with 14 cases including one case of Caroli's disease. There were 25 type BP cases and 10 type PB cases and 1 normal pancreatobiliary junction. Serum alkaline phosphatase was increased significantly in almost all cases. Seven patients (19.4%) had associated congenital anomalies such as double gallbladder, left - sided gallbladder, common bile duct web, biliary atresia, accessory hepatic duct, heterotopic pancreas, cleft lip and 2 cases of intestinal malrotation. All patients underwent cyst excision and Roux - en - Y hepaticojejunostomy and cholecystectomy. There was one death due to methicillin resistant Staphylococcus aureus sepsis.

Accelerated partial breast irradiation (APBI) is a new treatment delivery technique that decreases overall treatment time by using higher fractional doses than conventional fractionation. Here, a quantitative analysis study of CyberKnife-based APBI was performed on 10 patients with left-sided breast cancer who had already finished conventional treatment at the Inha University Hospital. Dosimetric parameters for four kinds of treatment plans (3D-CRT, IMRT, VMAT, and CyberKnife) were analyzed and compared with constraints in the NSABP B39/RTOG 0413 protocol and a published CyberKnife-based APBI study. For the 10 patients recruited in this study, all the dosimetric parameters, including target coverage and doses to normal structures, met the NSABP B39/RTOG 0413 protocol. Compared with other treatment plans, a more conformal dose to the target and better dose sparing of critical structures were observed in CyberKnife plans. Accelerated partial breast irradiation via CyberKnife is a suitable treatment delivery technique for partial breast irradiation and offers improvements over external beam APBI techniques.

Cancer-related facial pain refractory to pharmacologic management or nondestructive means is a major indication for destructive pain surgery. Stereotactic mesencephalotomy can be a valuable procedure in the management of cancer pain involving the upper extremities or the face, with the assistance of magnetic resonance imaging (MRI) and electrophysiologic mapping. A 72-year-old man presented with a 3-year history of intractable left-sided facial pain. When pharmacologic and nondestructive measures failed to provide pain alleviation, he was reexamined and diagnosed with inoperable hard palate cancer with intracranial extension. During the concurrent chemoradiation treatment, his cancer-related facial pain was aggravated and became medically intractable. After careful consideration, MRI-based stereotactic mesencephalotomy was performed at a point 5 mm behind the posterior commissure, 6 mm lateral to and 5 mm below the intercommissural plane using a 2-mm electrode, with the temperature of the electrode raised to $80^{\circ}C$ for 60 seconds. Up until now, the pain has been relatively well-controlled by intermittent intraventricular morphine injection and oral opioids, with the pain level remaining at visual analogue scale 4 or 5. Stereotactic mesencephalotomy with the use of high-resolution MRI and electrophysiologic localization is a valuable procedure in patients with cancer-related facial pain.
