Postpartum ovarian vein thrombosis has been thought to be a rare disease of which clinical finding is not accurate. Most of postpartum ovarian vein thrombosis presents as symptoms consisting of fever, lower abdominal pain, abdominal mass. If the symptom does not response even with intravenous antibiotics therapy or diagnosis is inaccurate, a ultrasound or a CT scan should be obtained for diagnosis. We report a case of postpartum ovarian vein thrombosis after cesarean section diagnosed and treated, with a brief review of literatures.

Portal vein thrombosis is a rare condition occuring in association with a wide varitey of precipitation factors. Among these, advanced hepatoma constitute the major etiology of portal vein thrombosis. Noncancerous intrahepatic portal vein occlusion was reported in some cases of repeated cholangitis. Generally, Intrahepatic stones occures in Lt. lobe of liver and repeated inflammatory precesses occlude peripheral branch of Lt. portal vein. So, noncancerous Rt. portal vein occlusion is extremly rare condition. Two Patients visited our hospital with Rt. upper quadrant abdominal pain and fever. Preoperative abdominal ultrasonography, computerlized tomography, endoscopic retrograde cholagiopancreaticography revealed multiple Rt. intrahepatic stones and Rt. portal vein 1st branch occlusion. Rt. lobectomy of liver were performed. Pathologic reports were portal vein occlusion due to inflammatory thrombi, not tumor thrombi. Thus authors experienced 2 cases of Rt. portal vein 1st branch occlusion due to noncancerous benign condition, such as multiple intrahepatic stones, we report these cases with brief review of literature.

Purpose: The cephalic arch is a significant site of stenosis in proximal arteriovenous fistulas (AVFs) that contributes to access dysfunction and thrombosis. This study aimed to evaluate the outcomes of surgical treatment (ST) and endovascular treatment (ET) for cephalic arch stenosis (CAS). Materials and Methods: A total of 62 patients with proximal AVF who underwent CAS revision using either ST or ET were enrolled between January 2018 and March 2023. In the ET group, only the initial ET following AVF formation was considered, to mitigate bias. In the ST group, central transposition of the native AVF (transposition group) or interposition of the prosthetic graft into the proximal basilic or axillary vein (interposition group) was performed. We evaluated primary and functional patency based on these groups and calculated the number of patency loss events after CAS treatment. Results: Of the 62 patients, 38 (61%) were male, with a mean age of 66.4 years. ST was performed in 26 (42%) patients, including transposition in 16 and interposition in 10, whereas ET was administered to 36 patients during the study period.Among the ST recipients, 42% had a history of ET for CAS. The incidence of AVF thrombosis was marginally higher in the ST group than in the ET group (39% vs.19%, P=0.098). The primary patency rates at 6 months, 1 year, and 3 years were 87%, 87%, and 66% in the transposition group; 45%, 23%, and 11% in the interposition group; and 66%, 49%, and 17% in the ET group, respectively. Notably, the primary patency of the transposition group was significantly higher than that of the interposition (P=0.001) and ET groups (P=0.016). The frequency of patency loss events per person-year after the initial revision was 0.40, 0.52, and 1.42 in the transposition, interposition, and ET groups, respectively. Conclusion Transposition exhibited the most favorable primary patency rate and the lowest number of subsequent patency loss events during follow-up despite the higher rates of AVF thrombosis and previous ET at presentation. Consequently, transposition should be actively considered in eligible patients with CAS.

BACKGROUND: The p16INK4a (p16) tumor suppressor gene is frequently inactivated in human non-small cell lung cancers (NSCLCs), predominantly through homozygous deletion or in association with aberrant promotor hypermethylation. Death-associated protein kinase (DAPK) gene influences interferon γ-induced apoptotic cell death and has important role in metastasis of lung cancer in animal model. Hypermethylation of promoter region of DAP kinase gene may suppress the expression of this gene. METHODS: This study was performed to investigate the aberrant methylation of p16 or DAP kinase in 35 resected primary NSCLCs by methylation-specific PCR (MSP), and demonstrated frequency, diagnostic value and clinical implication of aberrant methylation of two genes. RESULTS: Thirty-two cases were male patients, and 3 cases were female patients with an average age was 57.8±10.5 years. The histologic types of lung cancer were 22 of squamous cell carcinoma, 12 of adenocarcinoma, 1 of large cell carcinoma. Pathologic stages were 11 cases of stage I(1 IA,10 IB), 13 cases of stage II (1 IIA, 12 IIB), and 11 cases of stage III(9 IIIA, 2 IIIB). Regarding for the cancer tissue, p16 aberrant methylation was noted in 13 case of 33 cases (39.4%), DAP kinase in 21 cases of 35 cases (60%). Age over 55 year was associated with p16 aberrant methylation significantly (p<0.05). Methylation status of two genes was not different by smoking history, histologic type, size of tumor, lymph node metastasis and disease progression of lung cancer. There was no correlation between p16 and DAP kinase hypermethylation. CONCLUSION: This investigation demonstrates that aberrant methylation of p16 tumor suppressor gene or DAP kinase showed relatively high frequency (74.3%) in NSCLCs, and that these genes could be a biologic marker for early detection of lung cancer.

Pyomyositis is a bacterial infection of the skeletal muscle with Staphylococcus aureus being the most common pathogen. Pyomyositis by salmonella is quite rare accounting for less than 1% of the total pyomyositis, and has some different characteristics and a poor prognosis compared with those of the typical pyomyositis caused by other bacteria. Among these differences, an older age, other combined diseases, and an immune deficient condition are factors predisposing a patient to pyomyositis by salmonella. We experienced a very rare case of pyomyositis by salmonella at the inguinal area in a multiple myeloma patient. This is the first case reported in South Korea.

PURPOSE: To analyze the influences of fracture level and comminution, time to operation and reduction quality on the results of displaced femoral neck fractures in young adults. MATERIALS AND METHODS: From January 1996 to January 2003, 39 of 51 cases of displaced femoral neck fractures that were treated with closed reduction and percutaneous internal fixation using cannulated screws, were evaluated after at least two years of follow-up with respect to the fracture level, comminution, time to operation, and reduction quality. RESULTS: The incidence of AVN and non-union were 6/39 (15.4%) and 3/39 (7.7%), respectively. The differences in the incidences of complications among subcapital, transcapital, and subcapital fractures was not significant (p=1 & p=1). There was a higher incidence of AVN (p=0.0066) and non-union (p=0.0219) with posterior comminutions than anterior ones. The time to operation was not an important factor in influencing the development of complications (p=0.4984 & p=1). Between acceptable and poor reductions, the differences in the incidences of AVN was significant (p=0.0105), but not in the incidences of non-unions (p=0.1011). CONCLUSION: We concluded that good quality of reduction is more important than the time to operation for achieving good results, and that comminution is a more important prognostic factor than is the fracture level.

The aminoglycoside antibiotics is widely used in the treatment of infectious caused by gram-negative bacteria and for synergistic effect with(beta-lactam antibiotics. However, its therapeutic usefulness is limited by this potential nephrotoxicity and by disturbance of electrolyte homeostasis resulting in hypomagnesemia, hypokalemia, hypocalcemia such as Bartter-like syndrome. Many case repots have been reported on development of Bartter-like syndrome after aminoglycosides administration. But these reports had the many differences of such as types of aminoglycosides, age of patients, duration and total dose of treatment, combined antibiotics and baseline diseases. Therefore, the purpose of this study is to assess the effects of micronomocin sulfate on magnesium, calcium and potassium status of patients in acute pyelonephritis. Twenty one patients in acute pyelonephritis(18 female/3 male, ages 20-75) was treated with single or combined antibiotics. Eleven of twenty one patients as study group were treated with both micronomicin sulfate(aminoglycoside, 4mg/kg/day, during 5-8days) and flomoxef sodium (3rd cephalosporine, 2g/day, during 5-8days), and ten of twenty one patients as control group were treated only with flomoxef sodium(3rd cephalosporine. 2g/day. during 5-8days). Renal values, plasma and urinary electrolytes were measured before and at the end of IV antibiotic therapy. After micronomicin sulfate administrated for 6.4+/-1.5days, serum Mg, Ca, K, FEMg (fractional excretion of Mg), TTKG(transtubular K concentration gradient) and FECa(fractional excretion of Ca) did not significantly change(p>0.05). Therefore, those results suggest that micromonicin sulfate therapy within dose of 240mg/day(4mg/kg/day) for 6.4+/-1.5days may not cause disturbance of electrolyte homeostasis such as Bartter-like syndrome in acute pyelonephritis. Howerever, electrolyte disturbance is an important complication when aminoglycosides is given in larges doses over extended periods. Therefore, monitoring of blood concentration and urinary losses of electrolyte should be carried out along with careful observation of Bartter-like syndrome.

Chronic sclerosing mediastinitis is a rare disease of unknown etiology, pathologically characterized by chronic inflammation and fibrosis of mediastinal soft tissue. The process is often progressive and can occur either focally or diffusely throughout the mediastinum. This can result in compression of adjacent mediastinal structures, most commonly the low-pressure superior vena cava but also the pulmonary artery and vein, trachea and bronchi, esophagus and can result in a variety of functional and roentgenographic manifestation and occasionally death. We experienced a case of chronic sclerosing mediastinitis of unknown cause, which was confirmed by biopsy with thoracotomy, so reported it with a review of literature.

BACKGROUND: MUC1 mucin is a heavily glycosylated large glycoprotein and is expressed aberrantly in carcinoma. CD44 is polymorphic family of cell surface glycoproteins participating in cell-cell adhesion and modulat ion of the cell-matrix interaction. MUC1 mucin and CD44 expression have been implicated in a tumor invasion and metastasis in certain malignancies. In this study, the expression of MUC1 and the standard form of CD44(CD44s) was examined in non-small cell lung cancer (NSCLC). METHODS: Immunohistochemical staining using monoclonal antibodies including MUC1 glycoprotein and CD44s was performed on 80 NSCLC surgical specimens. The association between MUC1 and CD44s expression and the histological type and tumor stage was investigated. RESULTS: Depolarized MUC1 expression in more than 10% of cancer cells was found in 12 (27.9%) out of 43 squamous cell carcinomas (SCCs) and 12 (32.4%) out of 37 adenocarcinomas (ACs). It was not associated with the tumor histological type and the TNM-stage in SCCs. Depolarized MUC1 expression correlated with the N-stage in ACs (p=0.036). CD44s was expressed in 36 (83.7%) out of 43 SCCs and 14(37.8%) out of 37ACs. Reduced CD44s expression correlated with the N-stage (p=0.031) and the TNM-stage (p=0.0006) in SCCs. CONCLUSIONS: Depolarized MUC1 expression was related to the nodal stage in NSCLC adenocarcinoma. Reduced CD44s expression was related to nodal involvement and the TNM-stage in squamous cell carcinoma. This suggests that MUC1 and CD44s expression in NSCLC might play important roles in tumor progression and can be used as prognostic variables.

Ursolic acid (UA) supplementation was previously shown to improve skeletal muscle function in resistance-trained men. This study aimed to determine, using the same experimental paradigm, whether UA also has beneficial effects on exercise-induced skeletal muscle damage markers including the levels of cortisol, B-type natriuretic peptide (BNP), myoglobin, creatine kinase (CK), creatine kinase-myocardial band (CK-MB), and lactate dehydrogenase (LDH) in resistance-trained men. Sixteen healthy participants were randomly assigned to resistance training (RT) or RT+UA groups (n=8 per group). Participants were trained according to the RT program (60~80% of 1 repetition, 6 times/week), and the UA group was additionally given UA supplementation (450 mg/day) for 8 weeks. Blood samples were obtained before and after intervention, and cortisol, BNP, myoglobin, CK, CK-MB, and LDH levels were analyzed. Subjects who underwent RT alone showed no significant change in body composition and markers of skeletal muscle damage, whereas RT+UA group showed slightly decreased body weight and body fat percentage and slightly increased lean body mass, but without statistical significance. In addition, UA supplementation significantly decreased the BNP, CK, CK-MB, and LDH levels (p<0.05). In conclusion, UA supplementation alleviates increased skeletal muscle damage markers after RT. This finding provides evidence for a potential new therapy for resistance-trained men.
