Adapting pediatric health care responses to the COVID-19 pandemic in Japan: A clinical perspective.

The COVID-19 pandemic required our pediatric health care staff to adjust to many irregularities and solve serious issues in our routine clinical practice. In outpatient clinics, many children exhibited common cold symptoms that mimic COVID-19, thus we initially screened patients via an interview form, then later via SARS-CoV-2 antigen test. Cluster infections were entirely avoided by following systematic, everyday precautions. Patientsquality of life has been difficult to maintain during the pandemic, due to social and staffing restrictions. Other unexpected repercussions - such as an unexpected lack of seasonal virus infections, then a respiratory syncytial (RS) virus outbreak - required agile management of hospital resources. While we must continue to adapt our treatment programs in response to the evolving COVID-19 crisis, it remains essential to support the well-being of children through regular health check-ups, mental health support, educational opportunities, proper socialization, and close communication with parents and families.

Effectiveness of bisphosphonate combined with activated vitamin D in patients with aromatase inhibitor-induced osteoporosis after breast cancer operation.

OBJECTIVES: We compared the effectiveness of bisphosphonates combined with activated vitamin D administered for therapy of aromatase inhibitor-induced osteoporosis after a breast cancer operation and primary postmenopausal osteoporosis through propensity score matching. METHODS: Forty-eight postmenopausal patients with estrogen receptor-positive early breast cancer, who had postoperative adjuvant treatment with aromatase inhibitors and whose T-score of bone mineral density (BMD) decreased below -2.5 (AI group), and 48 patients of primary postmenopausal osteoporosis (PO group) enrolled in this retrospective observational study. They were administered monthly risedronate or minodronate, and daily alfacalcitol or eldecalcitol were combined. Their BMD (L2-4, L-BMD), serum-corrected calcium, serum phosphate, tartrate-resistant acid phosphatase 5b (TRACP-5b), bone alkaline phosphatase (BAP), estimated glomerular filtration rate, urine calcium/creatinine ratio, intact-parathyroid hormone, and 25-hydroxy vitamin D were measured before treatment and until 24 months. RESULTS: L-BMD values increased with time compared with the baseline values in each group, and there was no significant difference in the groups. Percentage value of TRACP-5b decreased rapidly after 6 months and maintained low level until 24 months in both groups. Percentage value of BAP in the AI group decreased continuously until 24 months. In contrast, the percentage change in the PO group plateaued after 6 months. CONCLUSIONS: It is suggested that monthly oral bisphosphonate combined with activated Vitamin D is an effective therapy to increase BMD in the aromatase inhibitor-induced osteoporosis after breast cancer operation. Monitoring of kidney function and concentration of Ca in blood and urine may be necessary.

Comparison of the effects of denosumab with either active vitamin D or native vitamin D on bone mineral density and bone turnover markers in postmenopausal osteoporosis.

Osteoporosis is a worldwide health concern. Although treatment with denosumab plus the active vitamin D alfacalcidol has been found to improve femoral neck (FN) and distal forearm bone mineral density (BMD), there have been no reports on the efficacy or adverse effects of denosumab plus eldecalcitol (ELD) in primary osteoporosis patients. Fifty-six treatment-naïve post-menopausal women with primary osteoporosis were recruited and divided into denosumab plus native vitamin D or denosumab plus ELD. Ultimately, 26 subjects in the native vitamin D group and 24 in the ELD group were analyzed. Lumbar and total hip BMD significantly increased in both groups. However, there was no significant difference in the percent increase of lumbar and total hip BMD between two groups. FN-BMD was significantly increased from 6 to 12 months in the ELD group compared with baseline. This study revealed that combination therapy with denosumab and ELD could improve FN-BMD more effectively than denosumab plus native vitamin D. Thus, the addition of ELD may enhance the effects of denosumab treatment for primary osteoporosis.

Moyamoya syndrome in a pediatric patient with congenital human immunodeficiency virus type 1 infection resulting in intracranial hemorrhage.

In the era of Antiretroviral Therapy (ART) in which human immunodeficiency virus type 1 (HIV-1) infection affected children can expect a better prognosis, the importance of careful follow up of pediatric HIV-1 cases for neurological complications has been growing. We present a case of hemorrhagic Moyamoya syndrome in a child with congenital HIV-1 infection. A 10-year-old girl was referred to our hospital for the treatment of Pneumocystis Jirovecii Pneumonia (PCP: Pneumocystis pneumonia). Her HIV-1 control was poor and Moyamoya syndrome was found during the opportunistic infection screening at admission. Despite subsequent successful treatment of PCP and HIV-1 infection, we could not save her life due to the intracranial hemorrhage caused by Moyamoya syndrome. A few reported cases of Moyamoya syndrome associated with HIV-1 infection have shown negative outcomes when the control of HIV-1 infection is unsuccessful. Recently "HIV-associated vasculopathy" has been used to describe the cerebrovascular disorder related to HIV-1 infection that is caused by the endothelial dysfunction induced from chronic inflammation and cytokine imbalances due to HIV-1 infection. We assumed that "HIV-associated vasculopathy" may have contributed to the development of collateral vessels impairment related to the bleeding, although the mechanism of vascular damage with HIV-1 infection is not yet well defined. Therefore proper management of the HIV-1 infection is crucial for Moyamoya syndrome with HIV-1 cases. Furthermore it is better to take into account the risk of intracerebral hemorrhage when considering the indication and timing of the revascularization surgery, although generally hemorrhaging is rare in Moyamoya disease in children.

Comparison of effectiveness and safety of ibandronate and minodronate combined with eldecalcitol in primary osteoporosis of women: A 1-year follow-up study.

OBJECTIVES: This is an open labeled and retrospective cohort study which compared the effectiveness and safety of ibandronate (IBN) and minodronate (MIN) combined with eldecalcitol (ELD) in primary osteoporosis of women. METHODS: One hundred and forty-eight primary osteoporotic women were classified into 3 groups; 1) intravenous IBN combined with oral ELD (IBN + ELD group, N = 50; 81.8 ± 6.2 years), 2) oral MIN combined with oral ELD (MIN + ELD group, N = 50; 77.2 ± 6.9 years) and 3) oral ELD alone (ELD group, N = 48; 75.0 ± 8.3 years). For statistical analysis, lumbar spine bone mineral density (L-BMD), hip total bone mineral density (H-BMD), serum corrected calcium (Ca), serum inorganic phosphorus (iP), intact-parathyroid hormone (PTH), tartrate-resistant acid phosphatase 5b (TRACP-5b), bone alkaline phosphatase (BAP), serum homocysteine (Hcy), estimated glomerular filtration rate (eGFR) and urine calcium / creatinine (Ca/Cr) ratio were measured until 12 months after the start of therapy. RESULTS: L-BMD values increased significantly in both IBN + ELD and MIN + ELD group, however, H-BMD increased significantly in the IBN + ELD group only. TRACP-5b values decreased rapidly during the first 6 months in both IBN + ELD and MIN + ELD group. However, BAP value in the IBN + ELD group decreased more gradually compared with that in the MIN + ELD group. Both serum Ca value and urine Ca/Cr ratio tended to increase, and the eGFR value decreased significantly in each group. CONCLUSIONS: IBN combined with ELD administration can act more effectively to increase BMD compared with MIN combined with ELD administration. Differences of decreasing rate in TRACP-5b and BAP value may lead to differences of increased rate of BMD in the IBN + ELD and MIN + ELD group. Because many cases of osteoporosis are elderly persons associated with chronic kidney disease, monitoring of kidney function and concentration of Ca in blood and urine is essential.

The cause of failure to return to the pre-fracture place of residence and solution to continue medical treatment for osteoporosis following an operation for hip fracture - Periodic observation of single center.

The purpose of this study was to investigate the causes of failure to return to the pre-fracture place of residence at hospital discharge following an operation for a hip fracture and to continue medical treatment for osteoporosis. Herein, we discuss methods for improving discharge protocols for these patients. We examined patients who sustained osteoporotic fractures and were operated on for a hip fracture between 2001 and 2003 (83 males and 386 females; 81.2 ± 9.0 years old) and between 2011 and 2013 (121 males and 462 females; 83.1 ± 9.3 years old). In a follow-up study, we examined patients who moved into our related rehabilitation institution over a 3-year period, from 2011 to 2013. The incidence of hip fractures had increased from 2001-2003 to 2011-2013 in both genders, and it tended to increase in patients greater than 80 years of age in male and 90 years of age in female. The most common destination residence after discharge from the rehabilitation institution was the pre-fracture place of residence. The Barthel Index at discharge from the rehabilitation institution was significantly lager in patients who returned to the pre-fracture place of residence compared to those who returned to nursing home and our hospital. These results suggest improved mobility and ADL level of patients enable them to return to the pre-fracture place of residence. We propose the construction of a feedback system that aids in a medical pass to increase the ambulant consultation rate for orthopedics and prevent fragile fractures.

The therapeutic effectiveness of the coadministration of weekly risedronate and proton pump inhibitor in osteoporosis treatment.

This trial was conducted to investigate the long-term effects of proton pump inhibitor (PPI) coadministration on the efficacy of weekly risedronate treatment for osteoporosis. Ninety-six women over 50 years old with low bone mineral density (BMD) participated in this trial. Subjects were randomly divided into 2 groups: a 17.5 mg dose of sodium risedronate was administered weekly, with or without a daily 10 mg dose of sodium rabeprazole (n = 49 and 47 in the BP + PPI and BP groups, resp.). The following biomarkers were measured at the baseline and every 3 months: bone-specific alkaline phosphatase, N-terminal telopeptide of type I collagen corrected for creatinine, parathyroid hormone, BMD of the lumbar spine, and physical parameters evaluated according to the SF-36v2 Health Survey. Statistical comparisons of these parameters were performed after 6, 12, 18, and 24 months. The Δ values of improvement in physical functioning after 12 months and bodily pain after 6 and 12 months in the BP + PPI group were significantly larger than those in the BP group. These results suggest that PPI does not adversely affect bone metabolism. Alternatively, approved bone formation by concomitant PPI treatment may have had favorable effects on the improvement of bodily pain and physical functions.
