ABSTRACT

During influenza epidemics, Japanese clinicians routinely conduct rapid influenza diagnostic tests (RIDTs) in patients with influenza-like illness, and patients with positive test results are treated with anti-influenza drugs within 48 h after the onset of illness. We assessed the vaccine effectiveness (VE) of inactivated influenza vaccine (IIV) in children (6 months-15 years old, N = 4243), using a test-negative case-control design based on the results of RIDTs in the 2018/19 season. The VE against influenza A(H1N1)pdm and A(H3N2) was analyzed separately using an RIDT kit specifically for detecting A(H1N1)pdm09. The adjusted VE against combined influenza A (H1N1pdm and H3N2) and against A(H1N1)pdm09 was 39% (95% confidence interval [CI], 30%-46%) and 74% (95% CI, 39%-89%), respectively. By contrast, the VE against non-A(H1N1)pdm09 influenza A (presumed to be H3N2) was very low at 7%. The adjusted VE for preventing hospitalization was 56% (95% CI, 16%-77%) against influenza A. The VE against A(H1N1)pdm09 was consistently high in our studies. By contrast, the VE against A(H3N2) was low not only in adults but also in children in the 2018/19 season.

ABSTRACT

HDR syndrome (OMIM #146255) is caused by haploinsufficiency of the GATA3 gene. A vascular ring has not been reported in patients with GATA3-associated HDR syndrome. We report a neonatal case of HDR syndrome and a vascular ring that were possibly due to a novel frameshift mutation in the GATA3 gene.

ABSTRACT

OBJECTIVES: We assessed the vaccine effectiveness (VE) of inactivated influenza vaccine (IIV) by vaccine dose in children aged 6 months to 12 years for whom two doses are recommended in Japan to ascertain the appropriate vaccine doses. METHODS: VE was assessed according to a test-negative case-control design based on rapid influenza diagnostic test (RIDT) results. Children aged 6 months to 12 years with a fever ≥38 °C who had received an RIDT in outpatient clinics of 24 hospitals were enrolled for all five seasons since 2013/14. VE by vaccine dose (none vs. once or twice, and once vs. twice) was analyzed. RESULTS: In the dose analysis, 20,033 children were enrolled. Both one- and two-dose regimens significantly reduced cases in preventing any influenza, influenza A, and influenza B, but there was no significant difference in adjusted VE between one- and two-dose regimens overall (adjusted OR, 0.560 [95% CI, 0.505-0.621], 0.550 [95% CI, 0.516-0.586]), 0.549 [95% CI, 0.517-0.583], and 1.014 [95% CI, 0.907-1.135], for none vs. once, none vs. twice, none vs. once or twice, and once vs. twice for any influenza, respectively). Both one- and two-dose regimens significantly reduced cases with any influenza and influenza A every season. Also, both regimens significantly reduced cases of any influenza, influenza A, and influenza B among children aged 1-12 years, especially among those aged 1-5 years. In the 2013/14, 2015/16, and 2016/17 seasons, however, only the two-dose regimen was significantly effective in preventing influenza B. Both one- and two-dose regimens significantly reduced cases involving hospitalization due to any influenza and influenza A. CONCLUSIONS: Both one- and two-doses regimens of IIV were effective in preventing influenza for children aged 6 months to 12 years. The two-dose regimen was more effective against influenza B in some seasons.

ABSTRACT

Infantile hepatic hemangioma (IHH) can be accompanied by consumptive hypothyroidism. We report the case of a 4-mo-old boy who showed massive hepatomegaly, peripheral coldness, lethargy, and failure to thrive. An enhanced computed tomography scans demonstrated multiple hemangiomas in both lobes of the liver, and a thyroid function tests showed severe hypothyroidism: TSH 561.5 µIU/mL, free triiodothyronine (fT3) 1.0 pg/mL, and free thyroxine (fT4) < 0.7 ng/dL. IHH gradually regressed following propranolol treatment and fT4 increased to a low normal level (1.0 ng/dL) by high dose replacement of levothyroxine, while fT3 remained very low (< 1.0 pg/mL), even following high doses of levothyroxine; fT3 eventually normalized following the administration of liothyronine. We suggest that treatment strategies should be individualized based on thyroid function, and that the combination therapy of propranolol for anti-tumor treatment and levothyroxine and liothyronine for respective thyroid hormone replacement is effective, particularly in cases of severe consumptive hypothyroidism due to multiple IHHs.

ABSTRACT

Intravenous leiomyomatosis (IVL) is an uncommon neoplasm characterized by the growth of a benign-looking smooth muscle tumor into the venous system. Intracardiac extension of this tumor is rare and may be misdiagnosed as right atrial myxoma unless the extracardiac part of the tumor is fully evaluated. We report a case of a 76-year-old woman whose preoperative diagnosis was right atrial myxoma. Intraoperative transesophageal echocardiography (TEE) revealed that the tumor had an extracardiac origin, resulting in tumor removal from the heart chamber and a part of the inferior vena cava (IVC) under circulatory arrest. When the findings of no attachment of the tumor to the interatrial septum or the right atrial wall and the tumor extension through the IVC are obtained by TEE examination, IVL should be considered as a differential diagnosis.

ABSTRACT

We report a case of a 35-year-old woman with myotonic dystrophy and severe obesity of BMI 43.3 who showed persistent apnea at emergence after ovarian resection. The patient received an iv induction with minimum dose of propofol and vecuronium 3 mg. Anesthesia was maintained with propofol, 50% nitrous oxide and 50% oxygen mixture and epidural anesthesia. Additional vecuronium 0.5 mg was administered twice. Surgery was performed uneventfully within 130 minutes and iv propofol was discontinued. The patient awoke promptly after termination of nitrous oxide but no spontaneous breathing appeared with end-tidal CO2 of 60 mmHg. Because she could obey the order to breathe, the endotracheal tube was removed 40 minutes after discontinuation of propofol. Spontaneous breathing at the rate of 17 x min(-1) started soon after extubation. We assume that this apnea was caused by breath holding. Whether this breath holding is specific to myotonic dystrophy or not, anesthesia for patients with this disease requires careful attention for perioperative respiratory management.
