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.

Blood supply of the sinus node artery in beagle dogs

Summary Postmortem coronary angiography was performed in 20 beagles and 15 mongrels, and the origin and distribution of the sinus node arteries (SNAs) were subsequently investigated using soft X-ray radiography, the tissue clearing method, and histological examination. In 19 of 20 beagles, the SNAs consisted of a single atrial branch originating from the right coronary artery, and the distribution pattern of the atrial branch seemed to be uniform. In contrast, the following three different patterns were recognized in the atrial branches forming the SNAs of mongrels: (1) distribution by two atrial branches, i.e., one originating from the right coronary artery and the other from the left circumflex artery, (2) dual distribution by two atrial branches originating from the right coronary artery, and (3) distribution by a single atrial branch originating from the right coronary artery or from the left circumflex artery. In 26 of the 30 dogs which were histologically examined, the SNAs ran outside of the sinus node and were not centrally located. In the beagles, the proximal atrial branch from the right coronary artery reached the atrioventricuolar node area and supplied blood to the atrioventricular node together with the arterial branches derived from the anterior septal artery and posterior septal artery. In addition, the arterial branch of the SNAs reached the atrioventricular junction area. These findings should contribute to clinical, pharmacological, and pathological studies of the cardiovascular system, including studies on cardiac arrhythmias in beagles.     

A Case Report of an Adult With Severe Hyperlipidemia During Acute Lymphocytic Leukemia Induction Therapy Successfully Treated With Plasmapheresis

Plasmapheresis for the treatment of hypertriglyceridemia has previously been performed in patients with sudden onset severe hypertriglyceridemia and acute pancreatitis; however, only a few reports of this procedure have been published. We report here on a case showing severe hypertriglyceridemia during asparaginase (Asp) treatment for acute lymphocytic leukemia (ALL), and give an overview of a lipid‐lowering apheresis therapy. To prevent the complication of pancreatitis due to hypertriglyceridemia, we performed plasma exchange (PE) three times using fresh frozen plasma. PE remarkably reduced both serum triglyceride and total cholesterol levels from 5430 mg/dL to 403 mg/dL and from 623 mg/dL to 204 mg/dL, respectively. The causes of severe hyperlipidemia in this patient were considered to include: the Asp treatment for ALL, and a genetic background with a heterozygote of familial lipoprotein lipase (LPL) defect syndrome, because the patient's plasma LPL level after intravenous heparin injection was low at 137 ng/mL. Hence, PE using fresh frozen plasma may be useful not only to remove lipoproteins, but also to supply defective factors, such as LPL, in similar cases.     

Incidence of human parvovirus B19 DNA detection in blood donors

Summary. 1000 serum samples from blood donors were tested for human parvovirus B19 (B19) DNA by a nested PCR assay: six samples were positive for B19 DNA. The frequency was 1/167 (0-6%), considerably higher than previous surveys (0-004-0-03%). Five of the six samples were also positive for anti-B19 IgM, indicating an acute phase of infection. It is recommended to screen for B19 DNA in blood products to prevent transfusion mediated viral infection for those susceptible such as immunocompromised patients and pregnant women.     

Rapidly growing mural thrombus in an abdominal aortic aneurysm

Summary While mural thrombus accompanied by an abdominal aortic aneurysm (AAA) is not rare, the growth rate of such a thrombus has not yet been adequately documented. We present here a very rare case of a 62-year-old female patient with an AAA in whom the mural thrombus in the aneurysm grew very rapidly over a short period. We could follow the growth of the mural thrombus in the AAA by two-dimensional (2-D) abdominal echography. Patients with an AAA must be closely monitored by this technique which is able to detect the presence of the thrombus and allow evaluation of its growth.     

Association study of G1704T and G82S polymorphisms of RAGE gene for microalbuminuria in Japanese type 2 diabetic patients

To clarify whether polymorphisms G1704T and G82S of the RAGE gene were related to microalbuminuria, we performed a case-control study in Japanese type 2 diabetic patients. Polymorphisms G1704T and G82S of the RAGE gene were examined with genomic DNA obtained from 116 type 2 diabetic patients with microalbuminuria (urinary albumin/creatinine ratio between 30 and 300 mg/g of creatinine) (microalbuminuria group), and 232 patients with normoalbuminuria (urinary albumin/creatinine ratio <30 mg/g of creatinine) (normoalbuminuria group). The genotype distribution and T allele frequency of G1704T (9.9%) and S allele frequency of G82S (14.2%) in the microalbuminuria group did not significantly differ from those (T allele frequency, 8.4%; S allele frequency, 12.3%) in the normoalbuminuria group. There were no differences among the genotypes of G1704T and G82S of the RAGE gene regarding age, duration of diabetes, body mass index, glycosylated hemoglobin (HbA1c), blood pressure, and serum lipid levels. These data suggest that G1704T and G82S polymorphisms of the RAGE gene are not related to microalbuminuria in Japanese type 2 diabetic patients.
