HighlightsWe report a case of Bochdalek hernia (BH) triggered by pregnancy in a pregnant adult.Laparoscopic surgery can be safely performed for BH without complications.We reviewed 30 cases of laparoscopic and/or thoracoscopic repair of adult BH.

When Saccharomyces cerevisiae strain 3626 was cultured to the stationary phase in a medium that contained glucose, needle-like structures that emitted autofluorescence were observed in almost all cells by fluorescence microscopy under UV excitation. The needle-like structures completely overlapped with the profile of straight elongated mitochondria. Therefore, these structures were designated as mitochondrial fluorescent inclusion bodies (MFIBs). The MFIB-enriched mitochondrial fractions were successfully isolated and 2D-gel electrophoresis revealed that a protein of 54 kDa was only highly concentrated in the fractions. Determination of the N-terminal amino acid sequence of the 54-kDa protein identified it as a mitochondrial aldehyde dehydrogenase, Ald4p. Immunofluorescence microscopy showed that anti-Ald4p antibody specifically stained MFIBs. Freeze-substitution electron microscopy demonstrated that cells that retained MFIBs had electron-dense filamentous structures with a diameter of 10 nm in straight elongated mitochondria. Immunoelectron microscopy showed that Ald4p was localized to the electron-dense filamentous structures in mitochondria. These results together showed that a major component of MFIBs is Ald4p. In addition, we demonstrate that MFIBs are common features that appear in mitochondria of many species of yeast.

Background/Aims: Because salvage surgery after definitive chemoradiotherapy for esophageal cancer is associated with high postoperative mortality and morbidity, minimally invasive methods are desirable. We analyzed the validity of minimally invasive salvage operations (MISO). Methods: Twenty-five patients underwent salvage operation between 2010 and 2016 in our institution, 10 having undergone right transthoracic salvage esophagectomy (TTSE group), 6 transhiatal salvage esophagectomy (THSE), 6 salvage lymphadenectomy (SLA), and 3 salvage endoscopic submucosal dissection (SESD). Patients who had undergone THSE, SLA, or SESD were categorized as the MISO group. Short- and long-term outcomes were assessed. Results: The mean duration of surgery was significantly shorter in the SLA groups than in the TTSE group (p = 0.0248). Blood loss was significantly less in the SLA than the TTSE group (p = 0.0340). Intensive care unit stay was shorter in the THSE than the TTSE group (p = 0.0412). There was no significant difference in postoperative mortality between the MISO and THSE groups. Postoperative hospital stay was significantly shorter in the SLA than the TTSE group (p = 0.0061). Patients’ survivals did not differ significantly between the MISO and TTSE groups (p = 0.752). Multivariate analysis revealed that residual disease (R0; HR 4.872, 95% CI 1.387–17.110, p = 0.013) was the only independent factor influencing overall survival. Conclusion: MISO is preferable because short-term outcomes are better and long-term outcomes do not differ from those of TTSE.

Background: This study aimed to examine the treatment outcomes of patients with brain metastases from esophageal cancer. Brain metastases from esophageal cancer are rare and have a poorer prognosis than brain metastases from lung and breast cancer. Methods: This study included patients who were diagnosed with and treated for esophageal cancer in our department and subsequently developed brain metastases between April 2010 and December 2014. We examined the differences in survival in patients based on receiving chemotherapy. Results: In total, 8 patients (7 men and 1 woman) with a mean age of 65 years (range 51–73) were included. Seven presented with neurologic symptoms. Two were diagnosed via computed tomography (CT), 5 via magnetic resonance imaging, and 1 via positron emission tomography/CT. They were treated using whole-brain irradiation or with a gamma knife. In 5 patients, chemotherapy was administered after treatment of the brain metastases. The mean survival from the start of treatment was 358 days (range 31–1196). Conclusion: The relatively successful local control of brain metastases in these patients indicates that long-term survival may be attainable via concomitant chemotherapy.

Objectives: Previously, adjuvant chemotherapy using oxaliplatin was a standard treatment for patients with node-positive colorectal cancer (CRC) who underwent curative surgery. The factor predicting adverse events and therapeutic effect have not yet been established. Methods: A retrospective cohort of 42 patients diagnosed with stage III CRC between April 2009 and March 2013 in our institution were included in this study. The indicators of host nutritional status were body weight (BW), body mass index (BMI), serum albumin, Onodera's prognostic nutritional index (OPNI), and Glasgow Prognostic Score (GPS). The indicators of host immunocompetence was total lymphocyte counts, total neutrophil counts, granulocytes/lymphocytes ratio (G/L ratio). Results: The overall recurrence rate was 26.1%. Patients who had a recurrence were more likely to be older. The recurrence was not associated with type of regimen or adverse events. The cases with a few cumulative doses and relative dose intensity of oxaliplatin experienced significantly more recurrence. Nutritional status indicators, such as the serum albumin level, OPNI, and the modified Glasgow prognostic score (mGPS) were associated with the adjuvant chemotherapy outcome. Our study results indicated worse nutritional status induced worse disease-free survival (DFS) and more recurrence. Conclusion: The host's nutritional status associated with outcomes in stage III CRC patients.
