Four patients underwent lumbar surgery. In all four patients, the dura was minimally torn during the operation. However, none exhibited signs of postoperative cerebrospinal fluid leakage. In each case, a few days after the operation, the patient suddenly experienced severe recurring pain in the leg. Repeat magnetic resonance imaging showed transdural nerve rootlets entrapped in the intervertebral disc space. On exploration, ventral dural tears and transdural nerve rootlet entrapment were confirmed. Midline durotomy, herniated rootlet repositioning, and ventral dural tear repair were performed, and patients' symptoms improved after rootlet repositioning. Even with minimal dural tearing, nerve rootlets may become entrapped, resulting in severe recurring symptoms. Therefore, the dural tear must be identified and repaired during the first operation.

Intramuscular hemangiomas are benign vascular lesions of skeletal muscle and constitutes less than 1% of all hemangiomas. Of all intramuscular hemangiomas, 13-25% occur in the head and neck, presenting lesions of enlarging soft tissue mass associated with pain. Usually they do not exhibit cutaneous changes, such as bluish skin discoloration as seen in cutaneous and superficial subcutaneous lesions. Because of their infrequency, deep location and unfamiliar presentation, intramuscular hemangomas are seldom correctly diagnosed clinically. We encountered a case of intramasseteric hemangioma in a 14-year-old female. She presented intermittent painful swelling on the right preauricular area. Sialography showed a multiple calcified lesion of the soft tissue, while CT scan and MRI showed a tumor mass lying in the masseter muscle. Angiography showed blush lesion but no tumor feeding arteries. After 6 months of intra-lesional sclerosing therapy with alcohol, total regression of tumor was obtained. As we experienced in this case, percutaneous sclerotherapy with alcohol could be the first therapeutic alternative.

The zygomaticomaxillary complex (ZMC) functions as a buttress for the face and is the cornerstone to a person's aesthetic appearance, by both setting the midfacial width and providing prominence to the cheek. Malar deficiency is often acquired by blunt injury incurred in a traumatic accident, resulting in ZMC fracture. A 48-year-old male patient presented a right ZMC fracture after contusion injury by a baseball. He only received conservative management and later he suffered discomfort during mouth opening at the moment of mastication, due to trismus involving the temporomandibular joint. In the current case, we describe a surgical technique, by which the malar body is shifted anteriorly and laterally after combined oblique-vertical osteotomy. The technique presented, eventually restored the former aesthetic position of the malar complex and symmetry, and, moreover, improved mastication function.

BACKGROUND: Tissue inflammation and remodeling have been extensively studied in various tumors in relation with their invasiveness and metastasis. OBJECTIVE: The purpose of this study was to investigate the change in tissue inflammation and remodeling markers in cutaneous squamous cell carcinoma (SCC). METHODS: Expression levels of cyclooxygenase-2 (COX-2) as an inflammatory marker and matrix metalloproteinases-2 and -9 (MMPs 2/9) as remodeling markers were studied in mouse and human SCCs. Western blot analysis and RT-PCR for COX-2 and MMPs 2/9 were performed with skin samples from SCC patients and chronic ultraviolet B (UVB)-induced SCC from hairless mice. RESULTS: mRNA and protein levels of COX-2 and MMPs 2/9 were up-regulated with the higher sensitivity for MMP-9 in mouse SCCs, which were induced by chronic UVB irradiation. Consistently, COX-2 and MMPs 2/9 were up-regulated with the higher sensitivity for MMP-9 in human SCCs. CONCLUSION: COX-2 and MMPs 2/9 are up-regulated in well-differentiated cutanous SCC. Our findings indicate that inflammatory and tissue remodeling processes are actively induced during carcinogenesis of cutaneous SCC.

Radical trachelectomy is a fertility-preserving alternative to radical hysterectomy in carefully selected young women with early-stage cervical cancer. However, in cases with subsequent severe cervical stenosis, assisted reproductive techniques can be difficult. This is a case report of a 34-year-old patient who underwent robot-assisted radical trachelectomy and cerclage for early-stage (IB2) adenosquamous carcinoma. Three months after surgery, the patient underwent ovarian stimulation using a gonadotropin-releasing hormone antagonist protocol. As it was impossible to perform transcervical embryo transfer due to the almost complete absence of the cervical opening, transmyometrial embryo transfer under ultrasound guidance was performed. This resulted in a successful singleton pregnancy. This is the first case of successful pregnancy conceived by in vitro fertilization with transmyometrial embryo transfer in a patient who had previously undergone robot-assisted radical trachelectomy.

Objective: The Patient Health Questionnaire–9 (PHQ-9) and PHQ-2 have not been validated in the general Korean population. This study aimed to validate and identify the optimal cutoff scores of the PHQ-9 and PHQ-2 in screening for major depression in the general Korean population. Methods: We used data from 6,022 participants of the Korean Epidemiological Catchment Area Study for Psychiatric Disorders in 2011. Major depression was diagnosed according to the Korean Composite International Diagnostic Interview. Validity, reliability, and receiver operating characteristic curve analyses were performed using the results of the PHQ-9 and Euro Quality of life-5 dimension (EQ-5d). Results: Of the 6,022 participants, 150 were diagnosed with major depression (2.5%). Both PHQ-9 and PHQ-2 demonstrated relatively high reliability and their scores were highly correlated with the “anxiety/depression” score of the EQ-5d. The optimal cutoff score of the PHQ-9 was 5, with a sensitivity of 89.9%, specificity of 84.1%, positive predictive value (PPV) of 12.6%, negative predictive value (NPV) of 99.7%, positive likelihood ratio (LR+) of 5.6, and negative likelihood ratio (LR-) of 0.12. The optimal cutoff score of the PHQ-2 was 2, with a sensitivity of 85.3%, specificity of 83.2%, PPV of 11.6%, NPV of 99.5%, LR+ of 5.1, and LR- of 0.18. Conclusion The PHQ-9 and PHQ-2 are valid tools for screening major depression in the general Korean population, with suggested cutoff values of 5 and 2 points, respectively.

PURPOSE: Clusterin is a heterodimeric glycoprotein and its expression is related with tissue injury and apotosis. Angitensisn II(ANG II) is known to be associated with the progression of renal disease by inducing renal fibrosis and cell proliferation. This study was designed to investigate the relationship between ANG II and clusterin expression in the kindey and the heart. We also attempted to discriminate the effect of ANG II-mediated hypertension by experimenting with two doses of ANG II-one is high enough to cause hypertension, and the other is not. METHODS: Three groups of Sprague-Dawley rats received ANG II infusion by osmotic minipump at a dose of 50ng/min, 100ng/min and placebo infusion, respectively. After 7 days, their kidneys and hearts were harvested and underwent immunohistochemical staining, RT-PCR, and Western blotting of clusterin. RESULTS: There were no differences in body weight nor organ weight/body weight among the three groups. Blood pressures of control and low-dose ANG group were not changed throughout the study, but that of high-dose ANG group was increased significantly at day 3 and 7. Staining for renal clusterin was diffusely distributed over the cortex and medulla in all 3 groups, but the intensity of staining was different notably in the medulla of control group which showed stronger staining than the ANG II infused groups. Staining intensity was not significantly different between the low and high ANG groups in the heart and kidney. In the kidney, expression of clusterin mRNA and protein were decreased in low-and high-dose ANG groups compared with control. In the heart, expression of clusterin mRNA was decreased in the low- and high-dose ANG groups compared with control. CONCLUSION: We conclude that ANG II decreases clusterin expression in the kidney and heart regardless of systemic hypertension induced by ANG II.

This report concerns an unusual case of acute postoperative pulmonary edema without any apparent causes in a 45-year-old man. The patient was subjected to the removal of a previously placed device on the left tibia, and the excision of a benign mass on the right forearm. Unexpected acute bilateral pulmonary edema occurred immediately after the completion of the procedures. The etiologies were reviewed in relation to the patient's condition and clinical manifestations. Fluid overloading was excluded as a cause in view of the patient's perioperative state and postoperative chest X-ray results. We could not find any symptoms of upper airway obstruction during emergence from general anesthesia. We had doubts about tourniquet or fentanyl-induced pulmonary edema, but these factors were not sufficient to bring about pulmonary edema in this case. To our knowledge, the cause of acute pulmonary edema in this case is indeterminate.
