Viruses are the major etiological agents of acute respiratory infections (ARIs) in young children. Although respiratory virus co-detections are common, analysis of combinations of co-detected viruses has never been conducted in Japan. Nineteen respiratory viruses or subtypes were surveyed using multiplex real-time PCR on 1,044 pediatric (patient age < 6 years) ARI specimens collected in Osaka City, Japan between January 2010 and December 2011. In total, 891 specimens (85.3z) were virus posi- tive (1,414 viruses were detected), and 388 of the virus-positive specimens (43.5z, 388/891) were posi- tive for multiple viruses. The ratio of multiple/total respiratory virus-positive specimens was high in children aged 0-35 months. Statistical analyses revealed that human bocavirus 1 and human adenovirus were synchronously co-detected. On the other hand, co-detections of human parainfluenza virus type 1 (HPIV-1) with HPIV-3, HPIV-3 with human metapneumovirus (hMPV), hMPV with respiratory syncy- tial virus A (RSV A), hMPV with influenza virus A (H1N1) 2009 (FLUA (H1N1) 2009), RSV A with RSV B, and human rhinovirus and FLUA (H1N1) 2009 were exclusive. These results suggest that young children (<3 years) are highly susceptible to respiratory viruses, and some combinations of viruses are synchronously or exclusively co-detected. © National Institute of Health.

Background: In patients with hemolytic anemia (HA), glycated hemoglobin (HbA 1C) presents lower values in relation to glycemia because the lifespan of erythrocytes is shortened, whereas glycated albumin (GA) is not affected. In the present study, we examined the usefulness of GA as an indicator of glycemic control status in patients with HA. Methods: We enrolled 21 patients with HA. A total of 202 patients with type 2 diabetes mellitus (T2DM) without complications were used as controls. Results: We identified a significant correlation between GA and HbA 1C in the patients with HA. However, in a comparison between the patients with HA and those with T2DM, the regression line showed a leftward shift in the former group. There was a significant positive correlation between hemoglobin (Hb) and HbA 1C in the patients with HA (R=0.541, p=0.025), although there was no significant correlation between Hb and GA. There was an inverse correlation between Hb levels and GA/HbA 1C ratio (R=-0.710, p=0.001). The measured HbA 1C levels were lower than the HbA 1C levels estimated from mean plasma glucose levels, whereas the GA/3 levels were close to the estimated HbA 1C levels. Conclusions: GA is a useful indicator of glycemic control status in patients with HA. © 2010 Elsevier B.V.

Purpose of review: We intend to update the data of various clinical features and management of sarcoidosis in the aged. Recent findings: Subclinical or inapparent systemic involvement of sarcoidosis was found at autopsy in elderly patients who died from sarcoidosis, complication of malignancy, or cerebrovascular accidents. Sarcoidosis in the aged presents with unusual intrathoracic and extrapulmonary clinical features. Occasionally, these features may masquerade as malignancy. Sarcoidosis may appear or reactivate in patients receiving treatment with tumor necrosis factor antagonists or antiviral treatment. In elderly patients, antitumour necrosis factor treatment is effective for refractory sarcoidosis, methylphenidate hydrochloride for fatigue, and bosentan for sarcoidosis-associated pulmonary hypertension. Inhaled prostacyclin has been found to be effective in some patients with pulmonary hypertension. Sarcoidosis and malignancy can coexist. Summary: Autopsy studies revealed that both apparent and subclinical or inapparent systemic involvement of sarcoidosis might exist in aged patients with sarcoidosis. Aged sarcoidosis patients often present with unusual clinical features of sarcoidosis. Occasionally, these features resemble malignancy. New treatment with tumor necrosis factor antagonists for intractable sarcoidosis, methylphenidate hydrochloride for fatigue, and bosentan for sarcoidosis-associated pulmonary hypertension may be effective in sarcoidosis in the aged. Sarcoidosis and malignancy may coexist. © 2010 Wolters Kluwer Health | Lippincott Williams and Wilkins.

Once a day of arbekacin (ABK) administrations based on a new object of peak concentration setting on 9-20 microg/mL were performed to 14 neonates. The gestational ages were 27.3 +/- 4.2 weeks. As to the preparing initial dosage, Therapeutic Drug Monitoring Program soft was used. Mean daily dose of 6.2 +/- 0.4 mg/kg bodyweight was administered every 24 to 48 h by 30 min intravenous infusion. Mean serum peak concentrations of ABK and those of trough concentrations were 15.2 +/- 4.3 microg/mL and 2.0 +/- 1.4 microg/mL respectively. The relationship between the measured values (y) and predicted values (x) showed the regression equation y = 0.969 + 0.931x (R2 = 0.769, n = 35), which suggested the usefulness of the dosage design. Overall clinical effectiveness was 78.9% (11/14). There were no obvious adverse effects including abnormal auto auditory brainstem responses and serum creatinine increase. Effectiveness rate and no adverse effects suggested that once a day of ABK therapy in neonate including extremely preterm infant was preferable regimen.

Aim: The aim of the present study was to show changes in salivary cortisol and chromogranin A/protein concentrations as stress markers during pregnancy and to clarify the effect of chronic stress on stress markers. Material and Methods: Salivary samples were collected from 69 pregnant women during pregnancy. Salivary cortisol levels and chromogranin A/protein titers were determined. We surveyed the women's chronic stress using the Zung self-rating depression scale and General Health Questionnaire-28. Results: Cortisol levels in the saliva of pregnant women showed biphasic change during pregnancy. Chromogranin A/protein levels in the saliva of pregnant women increased in the second and the early third trimesters and decreased to the puerperal period. Salivary cortisol concentrations of the chronic high stress group were significantly lower compared with those of the normal group. Salivary chromogranin A/protein concentrations of the chronic high stress group were also significantly lower than those of the normal group. Conclusion: The titration of salivary cortisol concentrations and chromogranin A/protein levels is a useful tool to determine maternal stress levels. The elevation of cortisol and chromogranin A/protein in the saliva was suppressed in the chronic high stress group during pregnancy. © 2011 The Authors.
