Autochthonous Dengue Fever,Tokyo, Japan, 2014

After 70 years with no confirmed autochthonous cases of dengue fever in Japan, 19 cases were reported during August–September 2014. Dengue virus serotype 1 was detected in 18 patients. Phylogenetic analysis of the envelope protein genome sequence from 3 patients revealed 100% identity with the strain from the first patient (2014) in Japan.     

Drug-induced Hypersensitivity Syndrome by EGFR-TKI in a Patient with Lung Cancer

An 83-years-old woman diagnosed with advanced Epidermal growth factor receptor (EGFR)-mutant lung adenocarcinoma was administered afatinib as a first-line treatment. On Day 17, the patient presented with grade 3 diarrhea and a blood test analysis showed an increased inflammatory response. Afatinib treatment was discontinued on the same day. On Day 26, the patient displayed blepharedema and multiple irregular erythema covering her entire body. Drug-induced hypersensitivity syndrome (DIHS) was suspected, and the systemic administration of 30 mg/day prednisolone was administered. The symptoms subsided thereafter. A blood test analysis 3 weeks after onset revealed a reactivation of Human herpesvirus 6 (HHV-6) and a diagnosis of DIHS due to afatinib therapy was confirmed.     

A novel procedure of puncture to access the pulmonary venous atrium in complex congenital heart disease with surgical correction

BackgroundIn complex congenital heart disease, supraventricular arrhythmia develops long term after surgical repair. The arrhythmia could have pharmacological tolerance and sometimes be fatal. We report our experiences with puncturing tough or calcified surgical repair material to access the pulmonary venous atrium for the purpose of the management of arrhythmia in complex congenital heart disease with surgical correction.MethodsFrom June 2016, subsequent 9 patients underwent the procedure. Their age at the procedure ranged from 11 to 43 years old (median 26.4 years old). Surgical procedures were Mustard procedure (Xenomedica^?) in 6, lateral tunnel total cavo-pulmonary connection with autologous pericardium in 2, and extra-cardiac total cavo-pulmonary connection with expanded polytetrafluoroethylene (ePTFE) tube in 1.ResultsMulti-planar reconstruction imaging by cardiac computed tomography was done for making plans before the procedures. Under intracardiac echocardiography guidance, an 8 French steerable sheath was perpendicularly adjusted to target objects. The sharpened edge of 0.014 inch guide wire penetrated with gentle forward force. Subsequently, the puncture site was dilated from a small balloon to a large one step by step. In all patients, penetration was successfully completed. Catheter ablation was achieved in 8 patients and a pacemaker was implanted through the re-canalized superior caval vein in 1 patient. No complications were recorded.ConclusionThe trans-catheter puncture of the synthetic or calcified material is safe and feasible, although careful planning is required with imaging. A steerable sheath could easily be controlled to the make appropriate angle to the target object for preventing slippage and conveying effective force.     

Anti-PM/Scl Antibody-positive Systemic Sclerosis Complicated by Multiple Organ Involvement

A 40-year-old Japanese woman developed malignant-phase hypertension complicated by thrombotic microangiopathy, progressing to end-stage renal disease. Five years later, she was diagnosed with pulmonary arterial hypertension and interstitial pneumonia. Despite a lack of overt skin sclerosis, nucleolar staining in our indirect immunofluorescence analysis and nailfold capillaroscopy facilitated the diagnosis of anti-PM/Scl antibody-positive systemic sclerosis. We observed the persistent presence of anti-PM/Scl antibodies throughout the clinical course, suggesting that her kidney disease was scleroderma renal crisis. Anti-PM/Scl antibodies can be associated with multiple organ diseases. Careful attention to a patient''s antinuclear antibody pattern and dermatological findings may help clarify the etiology of undiagnosed diseases.

Effect of a late evening snack on outpatients with liver cirrhosis

Aims: We have reported that one-week administration of a late evening snack (LES) improved not only malnutrition but also glucose intolerance in hospitalized patients with liver cirrhosis. Thus, we investigated whether long-term LES administration to outpatients for 3 months could reproduce the results obtained from hospitalized patients, especially improved glucose intolerance. If this treatment aggravated glucose intolerance, we tried to find any marker predicting this aggravation before the treatment. Methods: Outpatients were prescribed one pack of oral supplementation of a branched-chain amino acid (BCAA)-enriched nutrient, Aminoleban EN (210 kCal) as a LES without dietician supervision. Both before LES administration and after 3 months, glucose tolerance and liver function were examined using a 75 g oral glucose tolerance test (OGTT), biochemical parameters in blood and the relationship between glucose tolerance (area under the curve (AUC)) and the following serum markers. Results: Branched-chain amino acid/tyrosine ratio (BTR), the number of red blood cells (RBC), and hematocrit (Ht) significantly increased, with significant reduction of blood NH(3) level in patients with a blood glucose level less than 200 mg/dL 2 h after 75 g OGTT. However, the increase of AUC was seen after 3 months of LES administration in patients who had blood glucose higher than 200 mg/dL 2 h after 75 g OGTT. AUC weakly correlated positively with serum 7S collagen and negatively with choline esterase (ChE) and albumin (Alb). Conclusion: 75 g OGTT is a useful marker to predict the worst outcome and avoid the adverse effect of LES treatment in liver cirrhosis patients if performed without adequate nutrient conduct by a dietician.     

New quinolone versus vancomycin/tobramycin for intestinal sterilization in patients who undergo allogeneic bone marrow transplantation

The frequency of infection in recipients of allogeneic bone marrow transplants (BMT) who received oral new quinolones (NQ) was compared with that in BMT recipients who were given oral vancomycin/tobramycin (V/T). Between 1984 and 1997, our hospital treated 79 patients with V/T and 90 patients with NQ. Number of febrile days, duration of intravenous antibiotics administration, and frequency of documented infections were statistically the same for both groups. However, the frequency of grampositive bacterial infections, especially staphylococcal infections, was slightly higher in patients receiving NQ than in patients receiving V/T (p = 0.12). Of the patients who received NQ, those who underwent unrelated donor BMT procedures were generally febrile for slightly longer periods than those who underwent related donor BMT procedures (p = 0.10). These results suggest that oral NQ is as effective as oral V/T for the prevention of serious gramnegative bacterial infections in patients who undergo BMTs.
