In the unusual manifestation of right upper lobe collapse confusing with mediastinal or parenchymal mass, both alteration of the pulmonary vessels and shifting pattern of the collapsed lobe to the periphery on supine positionare the key to the diagnosis of it rather than mediastinal or parenchymal mass. The mechanisms of these unusual manifestation s are obscure, however lobar torsion and gravity factor are considered to be a main process. Authors have experienced 2 cases of unusual manifestations of right upper lobe collapse due to bronchogenic carcinomaduring resent 2 years in Kyung Hee University hospital, and prsent radiologic findings.

The goals of treatment in the injuries of posterior cruciate ligament(PCL) are restoration of normal tibiofemoral stability and reduction of long term osteoarthrosis of the knee. The purpose of this study is to analyze the factors on posterior stability and functional result after PCL reconstruction. From March 1996 to April 1997, twenty operation on PCL reconstruction were carried out in our hospital. The functional results according to the criteria of the Lysholm knee score and stress radiograph for posterior stability were evaluated. The average functional results evaluated by Lysholm knee score was 87. There was no significant difference in functional result according to selected grafted material, combined knee injury, type of injury and arthrotomy, etc. Difference in posterior tibial translation on average were 2.8mm in acute and 7.7mm in chronic injury. In posterolateral combined injury, average posterior tibial translation in pos- terolateral repair was 3.2mm and in posterolateral reconstruction was 9.4mm. In PCL reconstruction using hamstring with repair of PCL remnant was 2mm. In conclusion, to obtain the good result on posterior sta- bility, early PCL reconstruction using hamstring with repair of PCL remnant, and appropriate treatment on combined posterolateral injury were recommended.

Background/Objectives: Although thyroid lobectomy recently is considered as sufficient for low-risk papillary thyroid carcinoma (PTC), completion thyroidectomy is required due to the insufficiency of the preoperative evaluation. The aim of this study was to investigate recurrence rate and disease free survival depending on the gross extrathyroidal extension (gETE) or the number of metastatic lymph node identified in patients with PTC.Materials & Methods: We assessed 3373 patients with PTC who underwent lobectomy at Seoul St. Mary’s Hospital (Seoul, Korea) between January 2009 and December 2014. Clinicopathological characteristics and long-term surgical outcomes were retrospectively analyzed through complete chart reviews. The mean follow-up duration was 97.1 ± 21.4 months. Results: The rate of recurrence was higher in gETE group (1.8% vs. 6.0%, p=0.004), leading to decreased disease free survival in Kaplan-Meier analysis (log-rank p<0.001). N1 group (n=1389) was analyzed into two groups whether the number of positive nodes is more than 5 or less. For the group of the more metastatic nodes, the recurrence rate higher compared to the other group (3.0% vs. 9.3%, p<0.001). DFS was longer in the group that had lesser metastatic nodes (log-rank p<0.001). However, in terms of N1 group over 1cm (n=492), No statistical difference was observed according to the number of positive lymph nodes (4.5% vs. 9.1%, p=0.092) Conclusion When it comes to node positive PTC, Despite the number of positive lymph nodes was over 5, follow-up with no further surgery can be an option.

OBJECTIVE: Conization is used for diagnosis and treatment of cervical neoplasia. Our purpose of this investigation is to determine the efficacy of loop conization for the treatment of cervical dysplasia and the significance of the clinical and histological factors used to predict residual dysplasia after loop conization. METHODS: We reviewed the charts of patients who were received conization and subsequently total hysterectomy at Kangnam St Mary Hospital during 1989 and 2000. Logistic regression and Chi-square test were used for analysis. RESULTS: Total 257 patients were included. The mean age of the patients was 44.7 years. Of these patients, 87 (33.8%) had residual disease in the hysterectomy specimens. Age, the involvement of cut surface of endocervix and exocervix, severity and extent of the lesion, and scattering lesion were associated with the residual disease. But preoperative HPV infection, which is known as the cause of cervical neoplasia was not associated with the residual disease. CONCLUSION: When the high risk factors are present, the validity of conservative treatment should be considered and more careful follow up with pap smear, HPV test and colposcopy is necessary. Because about one thirds of patient has residual disease after conization, LEEP conization should be used for diagnosis of cervical neoplasia rather than treatment.

Congenital neonatal neuroblastoma is not uncommon but bilateral adrenal neuroblastoma is rare, accounting for about ten percent of neuroblastomas in children. We report the US and MR findings of a stage IV-S congenital bilateral neuroblastoma occurring in a one-day-old neonate.

A 73-year-old woman developed visual disturbances in the right side of the visual fields along with headache. A neurological examination showed right upper quadrantanopsia and right hemiachromatopsia. She reported that she could only see in shades of gray in the right hemifield. She also had difficulties in recognizing and naming the colors of objects presented in the right hemifield. A color-sorting test revealed generalized impairments involving all color axes. A brain MRI showed acute infarction in the left fusiform and lingual gyri.

Congenital lipoid adrenal hyperplasia (CLAH) is a rare autosomal recessive disorder characterized by the marked accumulation of lipids and cholesterol in the adrenal cortex, and the failure of adrenal steroids to synthesise. We report the ultrasound (US), computed tomographic (CT), and magnetic resonance (MR) imaging findings in a four-day- old female neonate with CLAH.

Pacemaker implantation for patients with mechanical tricuspid valve is quite challengeable because lead insertion through prosthetic tricuspid valve may cause valve dysfunction or lead impingement. Also complications due to interrupt of anticoagulation should be considered. A 65 years old woman received AAI (atrium paced, atrium sensed, inhibited) pacemaker for sick sinus syndrome and mechanical mitral valve replacement for severe mitral steno-insufficiency at the same time 16 years before. She needed to undergo mechanical tricuspid valve replacement (TVR) because of severe tricuspid regurgitation despite of medical therapy. Complete atrioventricular block developed during the TVR operation and it was not recovered even after several days of temporary pacing. We decided left ventricular pacing through coronary sinus because ventricular lead could not pass mechanical tricuspid or mitral valve and also planned to continue oral anticoagulation therapy. We could find a place where high pacing output did not pace phrenic nerve with acceptable sensing, pacing threshold. The patient recovered well without any periprocedural complications. Left ventriclcular pacing lead implantation through coronary sinus without interruption of anticoagulation can be an alternative to epicardial pacing for patients with mechanical tricuspid valve.

Scrub typhus is a zoonosis transmitted by a chigger of trombiculid mite and manifested with fever, skin rash, myalgia, and hepatitis etc. The renal involvement of the disease is prese-ted with transient microscopic hematuria and/or proteinuria. However acute renal failure or meningoencephalitis is very rare. We report a case of scrub typhus manifested with acute renal failure, meningoencephalitis, and hepatitis. The patient was treated with doxycycline and continuous arteriovenous hemofiltration (CAVH) and recovered successfully.
