[Case of pulmonary inflammatory pseudotumor with cysts].

We herein report a case involving a 58-year-old female patient with multiple cystic lesions in the right lobe of the lung. The lesions were revealed on chest computed tomography in 2002 and followed up. Transbronchial lung biopsy showed no malignancy in June 2013. The lesions gradually increased in size and thickness and were associated with fluid-filled cysts. We performed a right lower lobectomy in November 2013. Pathological examination revealed inflammatory pseudotumor. Such a case of inflammatory pseudotumor presenting as a pulmonary cyst has not been previously described. Intractable infection and inflammation are regarded as common causes of inflammatory pseudotumor. This condition should be considered in patients with a medical history consistent with infectious disease and a pulmonary cyst found on chest computed tomography.

[Case report of introducing MMF and steroids as an immunosuppressive therapy after living-donor liver transplantation for a patient with the diabetic nephropathy].

Calcineurin inhibitor (CNI) combined with mycophenolate mofetil (MMF) and steroid is mainly used as immunosuppressive therapy after the living-donor liver transplantation (LDLT). However, the nephrotoxicity caused by CNI remains a critical problem for patients with chronic renal failure, especially on early postoperative period. A 62-year-old woman with decompensated liver cirrhosis secondary to hepatitis B (Child-Pugh C, MELD score 11 points) and chronic renal failure due to diabetic nephropathy (Cr 1.56 mg/dl, GFR 27 ml/min/1.73 m2) experienced LDLT. During the reconstruction of hepatic vein, the supra-and infra-hepatic vena cava was totally clamped. The estimated right lobe liver graft volume was 540 g, representing 51.3% of the standard liver volume of the recipient. Because of the perioperative renal dysfunction due to diabetic nephropathy and the total clamping the vena cava which induced the congestion kidney, MMF (1500 mg/day) and steroid (250 mg/day converted into predonisolone) were mainly introduced as an immunosuppressive therapy after LDLT. The low-dose CNI, tacrolimus also induced the nephrotoxicity and was given for only a short time. Finally, according to the postoperative renal function, the low-dose CNI, cyclosporin (50 mg/day) was able to be added to the introduced immunosuppressive therapy. After having left the hospital, MMF (1500 mg/day), steroid (20 mg/day converted into predonisolone) and cyclosporin (75 mg/day) continued to be given as the immunosuppressive therapy and neither acute graft rejection nor drug-induced renal dysfunction was occurred. This is a case report of introducing with mainly MMF and steroid as an immunosuppressive therapy after LDLT for a patient with perioperative renal dysfunction.

Minimally invasive total pharyng-laryngo-esophagectomy and reconstruction with gastric tube: report of three cases.

Total pharyngo-laryngo-esophagectomy (TPLE) is indicated for either cervical esophageal cancer or synchronous double cancer of the thoracic esophagus and head and neck and this operation is extremely invasive. We adopted minimally invasive surgery for three patients who underwent this operation: VATS (video-assisted thoracoscopic surgery) esophagectomy was undergone in left semi-prone position and laparoscopic approach was also applied to reconstruction with gastric tube. After pharyngo-laryngectomy and gastric tube pull-up through post-mediastinal route, cervical anastomosis was performed. Free jejunal interposition was added in a case, while microvascular venous anastomosis between short gastric vein and cervical vein in another two cases. All patients recovered well without any postoperative complications. This is the first report, which describes minimally invasive TPLE using both VATS and laparoscopic technique in addition with plastic surgery.

Leptomeningeal carcinomatosis originating from advanced gastric cancer--a report of three cases and review of the literatures.

BACKGROUND: Leptomeningeal carcinomatosis (LMC) is a rare complication of gastric cancer. Case 1. A 57-year-old female was diagnosed with gastric cancer and underwent distal gastrectomy with D2 lymph node dissection. Two years later, the patient suffered from para-aortic lymph node metastases and provided chemotherapy. During the chemotherapy, the patient emergently visited our hospital with chief complaints of a severe headache and dizziness. The above symptoms promptly abated by meningeal drainage, with a high value of the cerebrospinal fluid (CSF) pressure. Despite the administration of subsequent chemotherapy, the patient's clinical state rapidly worsened, including gradual progression of both blindness and hearing loss. Case 2. A 42-year-old male was diagnosed with Stage IV gastric cancer due to both distant lymph node metastases and an ascites. Chemotherapy with S-1 plus docetaxel was initiated. Upon finishing the fifth course of treatment, the patient complained of a severe headache. The magnetic resonance imaging (MRI) findings were suggestive of LMC. Under suspicion of carcinomatous meningitis, the patient underwent both cerebrospinal drainage with a high pressure value of 180 mmH2O and a cytological examination with a diagnosis of Class V. Immediately following the cerebrospinal drainage, the patient's symptoms promptly diminished. Case 3. A 66-year-old female was diagnosed with gastric cancer and underwent total gastrectomy with D2 dissection. About a year later, the patient suffered from the peritoneal dissemination, and provided serial chemotherapy regimens for 13 months. Thereafter the patient suffered from mildly stiff shoulders followed by serial severe headaches, and meningeal drainage was performed. The CSF showed pleocytosis and the presence of neoplastic cells, leading a diagnosis of LMC. After the placement of an Ommaya reservoir, the intrathecal chemotherapy was performed. Within two weeks of treatment, the patient's condition improved significantly, and the cell counts in the CSF obtained from the Ommaya reservoir remained low for six months after the first diagnosis of LMC. CONCLUSIONS: Although gastric LMC-affected patients often exhibit a fatal clinical course, the administration of intrathecal chemotherapy may improve survival. Systemic chemotherapy may be also administered in a limited number of patients with a superior performance status. At present, each case requires the individual making treatment decisions. Further accumulation of clinical cases and improving the overall understanding of the pathogenesis of this disease is needed in order to advance in the treatment of gastric LMC.

Electrocardiographic diagnosis of the coronary artery culprit site in ischemic heart disease.

The diagnostic accuracy of using electrocardiographic findings to identify affected vessels in cases of myocardial infarction and angina pectoris treated by percutaneous transluminal coronary angioplasty was assessed. From the anterior wall leads, ST segment elevation in leads I and aV(L) showed diagnostic accuracy (sensitivity, specificity and positive predictive value) in identifying proximal lesions of the left anterior descending coronary artery of 89%, 58% and 62%, and the diagnostic accuracy of the QS wave in V(1) was 62%, 83% and 72%, respectively. For the posterior wall leads, the corresponding values for the diagnosis of affected vessels based on R/S>1 in V(1) for the left circumflex coronary artery were 50%, 89% and 60%, respectively. The inferior wall leads with ST segment elevation in leads II, III and aV(F), and ST segment depression in aV(L), showed diagnostic accuracy for the right coronary artery of 90%, 90% and 92%, respectively. Bifurcation of the first diagonal branch, dominance of the posterior descending branch, the normal subtypes of the coronary artery and the occurrence of spontaneous recanalization may have influenced the accuracy of diagnosis. Adding a high lateral wall lead one intercostal space above V(4) and a posterior wall lead located one intercostal space below V(6) appeared to increase the diagnostic accuracy of detecting the coronary artery lesions responsible for myocardial ischemia.

A pediatric case of secondary leukemia associated with t(16;21)(q24;q22) exhibiting the chimeric AML1-MTG16 gene.

A chimeric gene, AML1-MTG16, showing high homology to AML1-MTG8, was recently identified in adult leukemic patients with the abnormal karyotype t(16;21)(q24;q22). We recently saw a child patient of 11 years of age who developed acute myelogenous leukemia with the karyotype t(16;21)(q24;q22), 11 months after autologous peripheral blood stem-cell transplantation (PBSCT) for acute promyelocytic leukemia with karyotype t(15;17)(q22;q11). The reciprocal translocation was localized by fluorescence in situ hybridization (FISH) analysis, reverse transcription polymerase chain reaction (RT-PCR), and Southern blot analysis of bone marrow blood cells and peripheral blood cells. FISH analysis identified a reciprocal translocation between chromosomes 16 and 21. RT-PCR analysis identified expression of the chimeric gene AML1-MTG16. Southern blot analysis revealed a breakpoint occurring at a 1.4 kb Eco RI fragment between exons 3 and 4 of MTG16. The breakpoint is within the same region as that of secondary leukemias, which has been reported previously. This case suggests the possibility that the region of the breakpoint of MTG16 is a characteristic of secondary leukemia.
