Cases of acute myocardial infarction (AMI) that occur during pregnancy or postpartum are rarely reported. Ergot derivatives are known to induce the spasmodic contraction of coronary arteries. Administration of ergot derivatives can cause AMI, even in normal healthy people. In several reported cases, ergot derivatives triggered severe AMI during the postpartum period. Here, we report the case of a forty-year-old woman who was successfully impregnated by artificial fertilization and died after treatment with ergot derivatives. The autopsy revealed AMI with severe coronary atherosclerosis. This is the first case that reports aggravation of pre-existent severe coronary atherosclerosis after postpartum infusion of ergot derivtives.

Patients with chronic renal failure, generally, sufferred from normocytic normochromic anemia caused by decreased level of erythropoietin. But, secondary erythrocytosis has been reported in patients with several renal diseases; renal artery stenosis or throm- bosis, polycystic kidney disease, bilateral hydronephrosis, etc. We report one case of chronic renal failure combined with polycythemia vera. The case was 32 year-old man whose chief complaints were dyspnea, back pain, itching sensation, headache. 6 month ago, the laboratory examination showed only proteinuria and hematuria without deterioration of renal function. The renal function was aggravated with an accelerated course, and bone marrow examination revealed hypercellularity (erythroid predominance), and renal biopsy showed the finding of the end stage of renal disease which may be originated from IgA nephropathy.

OBJECTIVE: The purpose of this study was to analyze initial displacement and stress distribution of the maxillofacial complex during dentoskeletal maxillary protraction with various appliance designs placed on the palatal region by using three-dimensional finite element analysis. METHODS: Six models of maxillary protraction were developed: conventional facemask (Type A), facemask with dentoskeletal hybrid anchorage (Type B), facemask with a palatal plate (Type C), intraoral traction using a Class III palatal plate (Type D), facemask with a palatal plate combined with rapid maxillary expansion (RME; Type E), and Class III palatal plate intraoral traction with RME (Type F). In Types A, B, C, and D, maxillary protraction alone was performed, whereas in Types E and F, transverse expansion was performed simultaneously with maxillary protraction. RESULTS: Type C displayed the greatest amount of anterior dentoskeletal displacement in the sagittal plane. Types A and B resulted in similar amounts of anterior displacement of all the maxillofacial landmarks. Type D showed little movement, but Type E with expansion and the palatal plate displayed a larger range of movement of the maxillofacial landmarks in all directions. CONCLUSIONS: The palatal plate served as an effective skeletal anchor for use with the facemask in maxillary protraction. In contrast, the intraoral use of Class III palatal plates showed minimal skeletal and dental effects in maxillary protraction. In addition, palatal expansion with the protraction force showed minimal effect on the forward movement of the maxillary complex.

Phospholipase C (PLC) plays a role in ligand-mediated signal transduction for cellular activity such as proliferation and differentiation. A recent observation that PLC- gamma1 is highly expressed in some kinds of human cancer tissue supports the view that PLC-gamma1 may be involved in proliferation and carcinogenesis. PLC-gamma2 is known to be involved in B cell differentiation and maturation. However, there have been few studies about the expressions of PLC-gamma1 and gamma2 in human lymphoid malignancy. In the present study, we examined the contents of PLC-gamma1 and gamma2 in 10 cases of B cell, 10 cases of T cell non-Hodgkin's lymphoma and 5 cases of Hodgkin's lymphoma to find out whether these enzymes play any role in the carcinogenesis by immunohistochemistry and immunoprecipitation. Immunoprecipitation analysis revealed that in contrast to increased expression of PLC-gamma2 only in B cell lymphoma, a considerably higher level of PLC-gamma1 was detected in both B and T cell lymphoma. Immunohistochemical finding confirmed this observation. PLC-gamma1 and PLC-gamma2 were expressed in the cytoplasm of most tumor cells. PLC-gamma2 was also expressed in mature B cells, while PLC-gamma1 was not expressed in reactive non-tumor cells. These results suggest that PLC-gamma1 mediated signal transduction implicates a significant role in the carcinogenesis of all types of lymphoid tissue, and PLC-gamma2 may play a role in the carcinogenesis of B cell lymphoma as well as B cell differentiation.

Epidermolysis bullosa (EB) is a rare hereditary disorder characterized by formation of blisters following minor trauma. It has been traditionally categorized by the level of basement membrane zone separation into EB simplex (EBS), junctional EB (JEB), and dystrophic EB (DEB). Recently, hemidesmosomal EB has been proposed as a fourth category, which includes EB with muscular dystrophy and EB with pyloric atresia. We report here on a case of concomitant occurrence of EB and pyloric atresia, a rare form of EB.

PURPOSE: To evaluate the role of salvage radiotherapy (RT) for the treatment of regional lymph node recurrence (RLNR) after radical surgery in advanced gastric cancer. MATERIALS AND METHODS: We retrospectively analyzed medical records of 26 patients who underwent salvage treatment after diagnosis of RLNR between 2006 and 2011. Patients with peritoneal seeding or distant metastasis were excluded. Eighteen patients received RT with or without chemotherapy and the other 8 did chemotherapy only without RT. A three-dimensional conformal RT was performed with median dose of 56 Gy (range, 44 to 60 Gy). Sixteen patients had fluoropyrimidine-based chemotherapy, 5 did taxane-based chemotherapy, and irinotecan was applied in 4. RESULTS: With a median follow-up of 20 months (range, 5 to 57 months), median overall survival (OS) and progression-free survival (PFS) after diagnosis of RLNR were 29 months and 12 months in the entire patients, respectively. Radiotherapy (p = 0.007) and disease-free interval (p = 0.033) were statistically significant factors for OS in multivariate analysis. Median OS was 36 months in patients who received RT and 16 months in those who did not. Furthermore, delivery of RT (p < 0.001), complete remission after salvage treatment (p = 0.040) and performance status (p = 0.023) were associated with a significantly better PFS. Gastrointestinal toxicities from RT were mild in most patients. CONCLUSION: Salvage RT combined with systemic chemotherapy may be an effective treatment managing RLNR from advanced gastric cancer.

PURPOSE: To find the applicability of adjuvant radiotherapy for extrahepatic bile duct cancer (EBDC), we analyzed the pattern of failure and evaluate prognostic factors of locoregional failure after curative resection without adjuvant treatment. MATERIALS AND METHODS: In 97 patients with resected EBDC, the location of tumor was classified as proximal (n = 26) and distal (n = 71), using the junction of the cystic duct and common hepatic duct as the dividing point. Locoregional failure sites were categorized as follows: the hepatoduodenal ligament and tumor bed, the celiac artery and superior mesenteric artery, and other sites. RESULTS: The median follow-up time was 29 months for surviving patients. Three-year locoregional progression-free survival, progression-free survival, and overall survival rates were 50%, 42%, and 52%, respectively. Regarding initial failures, 79% and 81% were locoregional failures in proximal and distal EBDC patients, respectively. The most common site was the hepatoduodenal ligament and tumor bed. In the multivariate analysis, perineural invasion was associated with poor locoregional progression-free survival (p = 0.023) and progression-free survival (p = 0.012); and elevated postoperative CA19-9 (> or =37 U/mL) did with poor locoregional progression-free survival (p = 0.002), progression-free survival (p < 0.001) and overall survival (p < 0.001). CONCLUSION: Both proximal and distal EBDC showed remarkable proportion of locoregional failure. Perineural invasion and elevated postoperative CA19-9 were risk factors of locoregional failure. In these patients with high risk of locoregional failure, adjuvant radiotherapy could be considered to improve locoregional control.

Branchio-oto-renal (BOR) syndrome is a clinically heterogeneous autosomal dominant form of syndromic hearing loss characterized by variable hearing impairment, malformations of the pinnae, the presence of branchial arch remnants, and various renal abnormalities. BOR syndrome is caused by mutations in EYA1 and SIX1, which are critical to organogenesis and are expressed together in developing otic, branchial, and renal tissue. Branchio-otic (BO) syndrome comprises branchial fistulas and preauricular pits, but lacks renal anomalies. We present a case of BO syndrome in 30year-old man with a review of the literature.

BACKGROUND AND OBJECTIVES: Normal angiogenesis occurs as a part of the body's repair processes like the healing of wounds and fractures. By contrast, uncontrolled angiogenesis can often be pathological. Vascular remodelling could therefore play an important role in the growth process of solid tumors. The aim of this study was to detect the expression of platelet-derived endothelial cell growth factor (PD-ECGF), basic fibroblast growth factor (bFGF), and vascular endothelial growth factor (VEGF), and investigate the correlation between these factors. Also, we studied the relationships between the expressions of these factors and the clinical stage, nodal involvement, and histologic grade in the squamous cell carcinoma of larynx. MATERIALS AND METHOD: The authors examined the expression of three angiogenic factors in specimens of laryngeal squamous cell carcinoma (n=17). The mRNA expressions of angiogenic factors were detected by the semi-quantitative reverse transcription-polymerase chain reaction (RT-PCR). Statistics were analysed using the Fisher's exact test, the Wilcoxon signed rank test, and the Spearman correlation coefficiency. RESULTS: PD-ECGF and bFGF were significantly higher in the stages III and IV cancers than in the stages I and II cancers, and thus shows that bFGF was related to severity of the nodal involvement. The expression of more than one factor was significantly related with stages III and IV cancer. PD-ECGF and VEGF were related with each other. CONCLUSION: The authors suggest that angiogenic factors, especially, PD-ECGF and bFGF, may be used as prognostic factors for the squamous cell carcinoma of larynx.

Glomus tumor (glomangioma) is an uncommon, painful benign hyperplsia of the normal constituents of the glomus. The most common location is in the subungal region of the fingers. Occasionally, they are found in unusual locations, such as nasal cavity, stomach, mediastinum, trachea, heart, vagina and lung etc. Microscopically, they include small and large vascular spaces lined by a narrow endothelium surrounded by layers of cuboidal or spindle cells with rounded uniform nuclei in a loose stroma. Unusual locations and the difficulty of preoperative pathological confirmation can lead to misdiagnosis of malignancy. We present a case of glomangioma of neck in a 64-year-old female with a review of literature.
