Bronchial carcinoid tumor was a low grade malignant and it was regarded as predictable clinical course and good survivality after surgical resection. But despite of its low grade malignant potentiality, bronchial carcinoid tumor was clearly capable of metastasizing and causing death. We present 2 cases of bronchial carcinoid tumors. One of them was typical carcinoid tumor in 44 year-old female and another was atypical carcinoid tumor in 53 year-old male patient. Currative therapeutic procedure was performed by lobectomy and wedge resection.

Coronary stent dislodgement is a rare complication of percutaneous coronary intervention. We report a case of stent dislodgement in the ascending thoracic aorta. The stent was mechanically distorted in the left circumflex artery (LCX) while being delivered to the proximal LCX lesion. The balloon catheter was withdrawn, but the stent with the guide wire was remained in the ascending thoracic aorta. The stent was unable to be retrieved into the guide catheter, as it was distorted. A goose neck snare was used successfully to catch the stent in the ascending thoracic aorta and retrieved the stent externally via the arterial sheath.

In the fixation of patellar fractures, wiring techniques including tension band and cerclage wiring have been widely used. Some patients do not want to operation for removal of wire unless mechanical irritation is present. Authors report a case of a patient with migration of a broken wire to the popliteal fossa after the osteosynthesis of patellar fracture.

The incidence of small and asymptomatic pancreatic neuroendocrine neoplasms (PNENs) has been increased due to the widespread use of high-resolution imaging techniques and endoscopic procedures in screening programmes. Most of PNENs are indolent neoplasms with slow-growing. However, sometimes, PNENs show local invasion or metastasis with poor prognosis. The management of small, nonfunctioning PNENs remain under debate. The National Comprehensive Cancer Network guidelines recommend observation in selected cases of small PNENs less than 2 cm. Pancreatic surgeons are divided into two factions: “the hawks,” who indicate the high risk of malignancy even in small PNENs and, therefore, the need for an aggressive surgical treatment, and the “the doves,” who accepts the risk of malignancy in some ≤ 2 cm PNENs, advocate that the risk of overtreating many benign ≤ 2 cm PNENs would be much higher. As the pancreatic surgery remains a high-risk operation with a 28–30% morbidity and 1% mortality, the decision for small PNENs is challenging.

Endovascular aneurysm repair (EVAR) has been recommended as an alternative to open aneurysm repair. The risk of severe perioperative complications is lower than that in open surgical repair; however, late complications are more likely. After EVAR, regular yearly surveillance by duplex ultrasonography or computed tomography is recommended. We report the case of a 67-year-old man with a severely kinked left iliac branch of the stent graft 10 years after EVAR. He had not undergone regular follow-up during the last 4 years. We realigned the endograft kink by percutaneous transluminal angioplasty.

BACKGROUND: Functional mitral regurgitation (FMR) occurs commonly in patients with dilated cardiomyopathy (DCM). This study was conducted to explore the role of left ventricular (LV) dyssynchrony in developing FMR in patients with DCM in comparison with geometric parameters of the mitral apparatus. METHODS: Twenty patients without FMR and 33 patients with FMR [effective regurgitant orifice area (ERO) = 0.17 +/- 0.10 cm2] were enrolled. MR severity was estimated with ERO area. Dyssynchrony indices (DI) were measured using the standard deviations of time to peak myocardial systolic velocity between eight segments. Using real time 3D echocardiography, mitral valve tenting area (MVTa), anterior (APMD) and posterior papillary muscle distances (PPMD), LV sphericity, and tethering angle of anterior (Aalpha) and posterior leaflets (Palpha) were estimated. All geometrical measurements were corrected (c) by the height of each patient. RESULTS: The patient with FMR had significantly higher cDI, cMVTa, cAPMD and cPPMD, LV sphericity, Aalpha, and Palpha than the patients without FMR (all p < 0.05). With multiple logistic regression analysis, cMVTa (p = 0.017) found to be strongest predictor of FMR development. In patients with FMR, cMVTa (r = 0.868), cAPMD (r = 0.801), cPPMD (r = 0.742), Aalpha (r = 0.454), LV sphericity (r = 0.452), and DI (r = 0.410) showed significant correlation with ERO. On multivariate regression analysis, cMVTa and cAPMD (p < 0.001, p = 0.022, respectively) remained the strongest determinants of the degree of ERO and cAPMD (p < 0.001) remained the strongest determinant of the degree of cMVTa. CONCLUSION: Displacement of anterior papillary muscle and consequent mitral valve tenting seem to play a major role in developing FMR in DCM, while LV dyssynchrony seems to have no significant role.

Mucormycosis is a rare but invasive opportunistic fungal infection with increased frequency during chemotherapy-induced neutropenia. The clinical infections due to Mucor include rhinocerebral, pulmonary, cutaneous, gastrointestinal and disseminated diseases. The first two are the most common diseases and all entities are associated with a high mortality rate. Still hepatic involvement of Mucor is rarely reported. We experienced a case of hepatic and small bowel mucormycosis in a 56-year-old woman after induction chemotherapy for B-cell acute lymphocytic leukemia. Initial symptoms were a high fever unresponsive to broad spectrum antibiotics and pain in the left lower abdominal quadrant. It was followed by septic shock, deterioration of icterus and progressively elevated transaminase. An abdominal CT demonstrated multiple hypodense lesions with distinct margins in both lobes of liver and pericolic infiltration at small bowel and ascending colon. Diagnosis was confirmed by biopsy of the liver. The histopathology of the liver showed hyphae with the right-angle branching, typical of mucormycosis. The patient was managed with amphotericin B and operative correction of the perforated part of the small bowel was performed. However, the patient expired due to progressive hepatic failure despite corrective surgery and long-term amphotericin B therapy.
