Clinical characteristics of influenza virus-induced lower respiratory infection during the 2015 to 2016 season

Background

Influenza A(H1N1)pdm09 virus infections often manifest severe respiratory symptoms, particularly in patients with a past history of allergic disease. Most of these findings were reported during the 2009 pandemic. The purpose of this study was to detail the clinical characteristics of influenza virus-induced lower respiratory infection (LRI) during the A(H1N1)pdm09-predominant 2015–2016 season.

Caudal epidural anesthesia during intracavitary brachytherapy for cervical cancer

It has been suggested that pain control during intracavitary brachytherapy for cervical cancer is insufficient in most hospitals in Japan. Our hospital began using caudal epidural anesthesia during high-dose-rate (HDR) intracavitary brachytherapy in 2011. The purpose of the present study was to retrospectively investigate the effects of caudal epidural anesthesia during HDR intracavitary brachytherapy for cervical cancer patients. Caudal epidural anesthesia for 34 cervical cancer patients was performed during HDR intracavitary brachytherapy between October 2011 and August 2013. We used the patients'' self-reported Numeric Rating Scale (NRS) score at the first session of HDR intracavitary brachytherapy as a subjective evaluation of pain. We compared NRS scores of the patients with anesthesia with those of 30 patients who underwent HDR intracavitary brachytherapy without sacral epidural anesthesia at our hospital between May 2010 and August 2011. Caudal epidural anesthesia succeeded in 33 patients (97%), and the NRS score was recorded in 30 patients. The mean NRS score of the anesthesia group was 5.17 ± 2.97, significantly lower than that of the control group''s 6.80 ± 2.59 (P = 0.035). The caudal epidural block resulted in no side-effects. Caudal epidural anesthesia is an effective and safe anesthesia option during HDR intracavitary brachytherapy for cervical cancer.

Bronchoesophageal fistula in a patient with untreated malignant lymphoma

Bronchoesophageal fistulae associated with lymphomas are generally associated with chemo-radiotherapy. We report here an unusual case of lymphoma with a therapy-unrelated bronchoesophageal fistula. Previously, only 10 similar cases have been reported. A 70-year-old male was diagnosed as having gastric diffuse large B-cell lymphoma in May 1998. In January 1999, he noted a cough after eating and drinking. Because of the presence of a febrile temperature, productive cough and dyspnea, he was referred to our hospital and diagnosed as having aspiration pneumonia. Antibiotics did not improve his symptoms. When tracheal intubation was performed with bronchoscopy, a bronchoesophageal fistula was revealed. Malignant lymphoma cells were found around the fistula in the biopsy specimen. The patient died of pneumonia after treatment with airway stenting and chemotherapy. Induction of necrosis by chemotherapy or low blood flow with stenting and dopamine probably caused enlargement of the fistula.     

Exercise after heparin administration: new therapeutic program for patients with-option arteriosclerosis oblitrans.

BACKGROUND: A prospective study examined whether a combination of an exercise program and heparin administration improves the clinical symptoms of patients with arteriosclerosis obliterans (ASO) without an indication for surgical revascularization because of the lack of distal target vessels or other reasons such as high surgical risk or lack of a vein conduit from previous coronary artery bypass surgery. METHODS AND RESULTS: A total of 19 consecutive patients with symptomatic non-option ASO diagnosed by angiography were randomly assigned to 3 groups: heparin + exercise (walking for 60 min after heparin injection [3,000 units/day IV for 14 days], n = 6), heparin administration only (n = 6), and exercise only (n = 7). Plasma levels of hepatocyte growth factor (HGF) were serially measured before and after intravenous administration of heparin. Ankle brachial pressure index was measured and treadmill exercise test (2.5 km/h, 12% slope) was performed before the 2-week treatment, just after finishing treatment, and 12 weeks after beginning the treatment. Ophthalmic examinations, including visual acuity test, ocular fundoscopy and fluorescein angiographic fundus photography, were performed before and 12 weeks after the treatment program. In all patients, HGF levels increased more than 4-fold of the basal level at 30 min after heparin injection. Maximum walking time was significantly higher in the heparin + exercise group than in the other 2 groups (p < 0.05). There were no patients who showed pathological retinal angiogenesis. CONCLUSION: The combination of an exercise program and heparin administration improves the clinical symptoms of patients with non-option ASO.     

Liver-directed gene therapy for dyslipidemia and diabetes

This article provides an update of liver-directed gene therapy for dyslipidemia, reviewing papers published since 2002 and summarizing progress in gene transfer vectors. Despite the availability of polypharmacy and other therapeutic interventions, the treatment of severe dyslipidemia remains a challenge and continues to be an important target for experimental gene therapy. Gene therapy strategies that focus on long-term therapeutic efficacy of different regimens are emerging from small animal experiments, and new therapeutic genes and/or new approaches have been developed. A novel strategy for gene therapy for diabetes was published recently. Gene therapy for dyslipidemia and diabetes is still in its infancy. Nonetheless, recent progress in this area is encouraging and bodes well for the future.     

Detection of BCL2-IGH rearrangement on paraffin-embedded tissue sections obtained from a small submucosal tumor of the rectum in a patient with recurrent follicular lymphoma

A 59-year-old woman was admitted to our hospital because of recurrent follicular lymphorna (FL). Colonoscopic examination revealed a rectal submucosal tumor (SMT) without any erosions and ulcers. In this patient, it was difficult to distinguish non-Hodgkin‘s lymphoma (NHL) invasion from other disorders of the colon including carcinoid tumor merely based on endoscopic findings. Histopathologic and immunohistochemical studies on biopsy specimens showed an infiltration of atypical lymphocytes that were positive for CD20 and BCL2 but negative for UCHL-1. Fluorescence in situ hybridization on paraffin-embedded tissue sections (T-FISH) identified a translocation of BCL2 with IGHgene.Based on these findings, the tumor was defined as an invasion of FL. T-FISH method is useful for the detection of a monoclonality of atypical lymphocytes in an SMT of the gastrointestinal tract, and particularly for the detection of chromosomal translocations specific to lymphoma subtypes.
