The nursing shortage continues to be a problem in the United States, in part, owing to the experience of stress and burnout by practicing nurses. With an ageing population, the stress of caring for dying patients and their families is one reason for the high levels of stress and burnout. Although we know that caring for dying patients is stressful for nurses, there is little information about the specific aspects of that experience that concern them. In order to alleviate the stress and to help nurses cope more effectively with this situation, this research examined the aspects of caring for a dying patient that cause concern for nurses. This study used a grounded theory approach to examine the experiences of nurses and their particular concerns about caring for a dying patient. Nurses expressed personal concerns, concerns about the patient and their families, which include communication challenges with both patients and families. [ABSTRACT FROM AUTHOR]

Intracytoplasmic free calcium ions (Ca2+) are maintained at a very low concentration in mammalian tissue by the extrusion of Ca2+ across a steep extracellular Ca2+ gradient, mainly through the activity of plasma membrane Ca2+ pump-ATPase. The present study aimed to identify, by electron cytochemical and electron immunogold methods, the ultrastructural localizations of two types of plasma membrane Ca2+-ATPase; Ca2+-Mg2+-ATPase and Ca2+ pump-ATPase, in hepatic stellate cells. Liver tissues and isolated hepatic stellate cells (HSCs) were studied. The ultrastructural localization of Ca2+-Mg2+-ATPase activity was examined by the electron cytochemical method of Ando. The localization of Ca2+ pump-ATPase was identified by immunofluorescence. The ultrastructural localization of Ca2+ pump-ATPase was identified by the electron immunogold method. The cytochemical reaction products of Ca2+-Mg2+-ATPase activity were localized on the outer (cavity) side of the plasma membrane of caveolae. Immunofluorescence of Ca2+ pump-ATPase was seen as small dots along the cell edge in HSCs. Immunogold particles indicating the presence of Ca2+ pump-ATPase were identified on the inner (cytoplasmic) side of the plasma membrane of caveolae. We localized Ca2+ pump-ATPase on the inner side of the plasma membrane caveolae and Ca2+-Mg2+-ATPase on the outer leaflet of the caveolar plasma membrane in stellate cells, suggesting that Ca2+ pump-ATPase may play a key role in the Ca2+ reflux.

The intracytoplasmic free calcium ion (Ca2+) concentration is maintained at a low level in mammalian tissues by extruding Ca2+ against a high extracellular Ca2+ concentration, mainly through the activity of the plasma membrane Ca2+-ATPase pump. The objective of the present study was to localize the plasma membrane Ca2+-ATPase activity on hepatic sinusoidal endothelial cells (SECs) by electron microscopic cytochemistry. The ultrastructural localization of Ca2+-ATPase activity on ultrathin sections of liver tissue and cultured SEC monolayer was examined by the electron microscopic cytochemical method of Ando (method A: original method) and by our modified method (method B: shortened fixation method). By method A, scanty cytochemical reaction products of Ca2+-ATPase were found in the SECs. By method B, Ca2+-ATPase activity was clearly localized on the outer surface of the plasma membrane of sinusoidal endothelial fenestrae (SEF). Our modification of Ando's method by shortening the incubation time of liver tissue or isolated SEC sections in the substrate allowed clear demonstration of Ca2+-ATPase activity on the SEF membrane. Use of tangential sections of primary cultures of SEC provided excellent localization results. The cytochemically reactive Ca2+-ATPase expressed on the SEF plasma membrane may be involved in regulation of the intracytoplasmic Ca2+ concentration. [ABSTRACT FROM AUTHOR]

Aim: In frozen-thawed embryo transfer (FET), differences in endometrial preparation methods affect the incidence of perinatal complications. However, the underlying causes are unclear. We aimed to investigate whether serum E2, P4 levels are associated with perinatal complications., Methods: This is a retrospective cohort study, involving 306 successful FET pregnancies from 2017 to 2022. Participants were divided into Natural Cycle (NC) and Hormone Replacement Cycle (HRC) group. We compared serum hormone levels, maternal backgrounds, and perinatal outcomes and complications. Furthermore, within the HRC group, serum hormone levels were compared for perinatal complications previously reported to show differences in incidence rates depending on the method of endometrial preparation., Results: HRC exhibited significantly higher serum E2 levels during the implantation period, but lower P4 levels during ovulation, implantation, and pregnancy test period compared with NC. HRC also had significantly higher rates of postpartum hemorrhage (PPH) and placenta accreta spectrum (PAS). There was no association found between perinatal complications more likely to occur in HRC and serum E2, P4 levels., Conclusions: In HRC, there were more occurrences of PPH and PAS. Although serum E2, P4 levels during FET did not correlate with perinatal complications., (© 2024 Japan Society of Obstetrics and Gynecology.)

Purpose: To describe the real-world treatment patterns of systemic therapies for biliary tract cancer (BTC) and to examine the frequency and management of biliary infection in Japan., Methods: Patients diagnosed with BTC and prescribed systemic therapy between January 2011 and September 2020 were retrieved from the Japanese Medical Data Vision database. The look-back period was set to 5 years. Patient characteristics, treatment patterns, and biliary infection-induced treatment interruption were analyzed., Results: The full analysis set comprised 22 742 patients with a mean age of 71.0 years and 61.6% were male. The most common BTC type was extrahepatic cholangiocarcinoma (44.6%). The three most common first-line regimens were S-1 monotherapy (33.0%), gemcitabine+cisplatin (32.5%), and gemcitabine monotherapy (18.7%) over the entire observation period (January 2011-September 2021). Patients who received monotherapies tended to be older. Biliary infection-induced treatment interruption occurred in 29.5% of patients, with a median time to onset of 64.0 (interquartile range 29.0-145.0) days. The median duration of intravenous antibiotics was 12.0 (interquartile range 4.0-92.0) days., Conclusions: These results demonstrated potential challenges of BTC in Japanese clinical practice particularly use of multiple regimens, commonly monotherapies, which are not recommended as first-line treatment, and the management of biliary infections during systemic therapy., (© 2024 The Authors.

Aim: This study was undertaken to investigate the utility of the fatty liver index (FLI) as a noninvasive tool for predicting hepatic steatosis based on alcohol consumption and sex in a large Asian population., Methods: We carried out a single-center observational cohort study at the HITO Medical Center in Japan and enrolled 1976 Asian subjects. The subjects were categorized into nondrinkers and light drinkers (0-19 g/day) and moderate drinkers (20-59 g/day) based on their self-reported alcohol intake. We used physical examinations, laboratory tests, and a questionnaire to collect information on various factors related to the FLI, including body mass index, waist circumference, and levels of γ-glutamyl transferase and triglycerides., Results: The diagnostic accuracy of the FLI was assessed by calculating the area under the receiver operating characteristic curve (AUROC), and optimal cut-off values were determined using Youden's index. The FLI had an acceptable performance index of >0.7 both overall and in all subgroups, with an overall AUROC of 0.844. The AUROCs were higher in women and moderate drinkers of both sexes. We also compared the cut-off values obtained in the present study with the previously reported values of 30 and 60. Optimal cut-off values for the FLI were calculated for the total population and subgroups and were found to differ from the previously established values in other countries., Conclusions: Our study suggests that the FLI is a useful noninvasive marker for predicting hepatic steatosis in a large Asian population, irrespective of alcohol consumption and sex., (© 2023 Japan Society of Hepatology.)

Oral ferric citrate hydrate (FCH) is effective for iron deficiencies in hemodialysis patients; however, how iron balance in the body affects iron absorption in the intestinal tract remains unclear. This prospective observational study (Riona-Oral Iron Absorption Trial, R-OIAT, UMIN 000031406) was conducted at 42 hemodialysis centers in Japan, wherein 268 hemodialysis patients without inflammation were enrolled and treated with a fixed amount of FCH for 6 months. We assessed the predictive value of hepcidin-25 for iron absorption and iron shift between ferritin (FTN) and red blood cells (RBCs) following FCH therapy. Serum iron changes at 2 h (ΔFe2h) after FCH ingestion were evaluated as iron absorption. The primary outcome was the quantitative delineation of iron variables with respect to ΔFe2h, and the secondary outcome was the description of the predictors of the body's iron balance. Generalized estimating equations (GEEs) were used to identify the determinants of iron absorption during each phase of FCH treatment. ΔFe2h increased when hepcidin-25 and TSAT decreased (-0.459, -0.643 to -0.276, p = 0.000; -0.648, -1.099 to -0.197, p = 0.005, respectively) in GEEs. FTN increased when RBCs decreased (-1.392, -1.749 to -1.035, p = 0.000) and hepcidin-25 increased (0.297, 0.239 to 0.355, p = 0.000). Limiting erythropoiesis to maintain hemoglobin levels induces RBC reduction in hemodialysis patients, resulting in increased hepcidin-25 and FTN levels. Hepcidin-25 production may prompt an iron shift from RBC iron to FTN iron, inhibiting iron absorption even with continued FCH intake.

Background: The utility of dipstick proteinuria for predicting microalbuminuria in non-diabetic lifestyle-related diseases compared with the urine protein-to-creatinine ratio (uPCR) and the effect of dipstick proteinuria on the cut-off value (CO) and accuracy of uPCR are unclear., Methods: The subjects included Japanese patients ≥ 18 years old with lifestyle-related diseases who had an estimated glomerular filtration rate of ≥ 15 ml/min/1.73 m 2 and uPCR of < 0.5 g/gCr at initiation. Urine dipstick, uPCR and urine albumin-to-creatinine ratio (uACR) were measured three times per case. Microalbuminuria was defined as uACR of 30-299 mg/gCr for at least 2 of 3 measurements. Youden's Index was used as the optimal CO. Factors associated with microalbuminuria were analyzed using a logistic regression model., Results: In 313 non-diabetic cases (median 70.8 years old), 3 dipstick proteinuria measurements were independently useful for detecting microalbuminuria, and the CO was set when a trace finding was obtained at least 1 of 3 times (sensitivity 0.56, specificity 0.80, positive predictive value [PPV] 0.73, negative predictive value [NPV] 0.65). A single uPCR measurement was more useful than 3 dipstick measurements, and was useful for detecting microalbuminuria even in cases with three consecutive negative proteinuria findings, indicating that the CO of the second uPCR with G1-3a (n = 136) was 0.06 g/gCr (sensitivity 0.76, specificity 0.84. PPV 0.68, NPV 0.89), while that with G3-b4 (n = 59) was 0.10 g/gCr (sensitivity 0.56, specificity 0.91. PPV 0.83, NPV 0.71). The sum of 3 uPCRs was useful for detecting microalbuminuria in cases with G1-3a (sensitivity 0.67, specificity 0.94, PPV 0.82, NPV 0.86) and G3b-4 (sensitivity 0.78, specificity 0.94, PPV 0.91 NPV 0.83), with both COs being 0.23 g/gCr. These COs of microalbuminuria did not change when trace or more proteinuria was included, although the sensitivity increased. A high uPCR and low urine specific gravity or creatinine level were independent factors for uACR ≥ 30 mg/gCr in cases with negative proteinuria, although the uPCR was a major predictive factor of a uACR ≥ 30 mg/gCr., Conclusions: The uPCR (preferably determined using early-morning urine), including in dipstick-negative proteinuria cases with non-diabetic lifestyle-related diseases, can aid in the early detection of microalbuminuria., Trial Registration: Retrospectively registered., (© 2022.

Lemierre's syndrome is characterized by internal jugular vein thrombosis and systemic septic embolism; it is a fatal complication of upper respiratory tract infections. To date, it has not been demonstrated how the upper respiratory tract inflammation spreads from the primary infection site to internal jugular vein and systemic thrombosis. We report a very rare case of Lemierre's syndrome derived from malignant otitis externa in which the spread of infection and thrombosis process were identified by imaging. A 61-year-old man with severe diabetes mellitus visited our hospital with consciousness disturbance and right posterior neck pain. He complained of right ear pain and otorrhea several days prior to the neck pain. Contrast-enhanced computed tomography demonstrated thrombosis in internal jugular vein and multiple lung abscesses. Temporal bone images revealed continuous lesions from skull base osteomyelitis to suboccipital abscess and sigmoid sinus thrombosis. We diagnosed the patient as having Lemierre's syndrome secondary to skull base osteomyelitis following malignant otitis externa. The patient clinically recovered with a combination of drainage of suboccipital abscess and long-term administration of antibiotics, which is the standard treatment of malignant otitis externa. Considering the details of imaging and bacterial examination is very useful for understanding the pathophysiology and determining appropriate treatment in Lemierre's syndrome pathophysiology and determining appropriate treatment in Lemierre's syndrome.

Objective  Diagnostic criteria for otogenic skull base osteomyelitis (SBO) have been conflicting among researchers. We aimed to propose clinically useful diagnostic criteria and a staging system for otogenic SBO that is associated with infection control and mortality. Design  The present study is designed as a retrospective one. Setting  This study was conducted at the University Hospital. Participants  Thirteen patients with otogenic SBO who met the novel rigorous diagnostic criteria consisted of symptomatic and radiological signs on high-resolution computed tomography (HRCT) and magnetic resonance imaging (MRI). Simple refractory external otitis was not included. A staging system according to disease extent revealed by HRCT and MRI is proposed: lesions limited to the temporal bone (stage 1), extending to less than half (stage 2), exceeding the midline (stage 3), and extending to the whole of the clivus (stage 4). All patients received long-term antibiotic therapy. Patients were divided into infection-uncontrolled or -controlled groups based on symptoms, otoscopic findings, and C-reactive protein level at the last follow-up. The mean follow-up period was 27.7 months. Main Outcome Measures  Possible prognostic factors, such as immunocompromised status and symptoms, including cranial nerve palsy, pretreatment laboratory data, and treatments, were compared between the infection-uncontrolled and -controlled groups. Disease stages were correlated with infection control and mortality. Results  The infection-uncontrolled rate and mortality rate were 38.5 and 23.1%, respectively. There were no significant differences in possible prognostic factors between the infection-uncontrolled and -controlled groups. HRCT-based stages significantly correlated with infection control and mortality. Conclusion  We proposed here the clinically useful diagnostic criteria and staging systems that can predict infection control and prognosis of otogenic SBO., Competing Interests: Conflict of Interest None declared., (Thieme.

Background: To suppress increases in kidney failure and cardiovascular disease due to lifestyle-related diseases other than diabetes, early intervention is desirable. We examined whether microalbuminuria could be predicted from proteinuria., Methods: The participants consisted of adults who exhibited a urinary protein-to-creatinine ratio (uPCR) of < 0.5 g/gCr and an eGFR of ≥ 15 ml/min/1.73 m 2 in their spot urine at their first examination for lifestyle-related disease. Urine was tested three times for each case, with microalbuminuria defined as a urinary albumin-to-creatinine ratio (uACR) of 30-299 mg/gCr, at least twice on three measurements. Youden's Index was used as an index of the cut-off value (CO) according to the ROC curve., Results: A single uPCR was useful for differentiating normoalbuminuria and micro- and macroalbuminuria in patients with non-diabetic lifestyle-related diseases. Regarding the GFR categories, the CO of the second uPCR was 0.09 g/gCr (AUC 0.89, sensitivity 0.76, specificity 0.89) in G1-4 (n = 197) and 0.07 g/gCr (AUC 0.92, sensitivity 0.85, specificity 0.88) in G1-3a (n = 125). Using the sum of two or three uPCR measurements was more useful than a single uPCR for differentiating microalbuminuria in non-diabetic lifestyle disease [CO, 0.16 g/gCr (AUC 0.91, sensitivity 0.85, specificity 0.87) and 0.23 g/gCr (AUC 0.92, sensitivity 0.88, specificity 0.84), respectively]., Conclusion: Microalbuminuria in Japanese individuals with non-diabetic lifestyle-related diseases can be predicted from the uPCR, wherein the CO of the uPCR that differentiates normoalbuminuria and micro- and macroalbuminuria was 0.07 g/gCr for G1-3a, while that in G3b-4 was 0.09 g/gCr.

Background: Providing palliative care patients living at home with timely access to medicines is critical to enable effective symptom management, minimise burden and reduce unplanned use of healthcare services. Little is known about how diverse community-based palliative care models influence medicine access., Objective: To produce a critical overview of research on experiences and outcomes of medicine access in community-based palliative care models of service delivery through a systematic review and narrative synthesis., Methods: MEDLINE, CINAHL, EMBASE, PsycINFO, Cochrane Library databases and grey literature were systematically searched for all types of studies. Study quality was assessed using the Mixed Methods Appraisal Tool; a narrative synthesis was used to integrate and summarise findings., Results: 3331 articles were screened; 10 studies were included in the final sample. Studies included a focus on community pharmacy (n=4), hospice emergency medication kits (HEMKs) in the home (n=3), specialist community nurse prescribers (n=1), general practice (n=1) and one study included multiple service delivery components. Community pharmacy was characterised by access delays due to lack of availability of medicine stock and communication difficulties between the pharmacy and other healthcare professionals. HEMKs were perceived to reduce medicine access time out of hours and speed symptom control. However, the majority of studies comprised small, local samples, largely limited to self-reports of health professionals. There was a lack of data on outcomes, and no comparisons between service delivery models., Conclusions: Further research is required to understand which models facilitate rapid and efficient access to medicines for community-based palliative care patients., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Purpose: Previous studies have reported different methods of estrogen administration during endometrial preparation for frozen-thawed embryo transfer (FET). This study aimed to investigate a beneficial regimen of transdermal estrogen administration for FET., Methods: We investigated the reproductive and obstetric outcomes of FET by comparing the increasing dose (ID) group that mimics changes in serum estradiol during the menstrual cycle and the constant dose (CD) group. Transdermal patches were used for estrogen administration in both groups. In our hospital, we targeted 315 cycles of the ID group in which FET was performed in 2017 and 324 cycles of the CD group in which FET was performed in 2018. In all cases, single embryo transfer was performed., Results: All were singleton pregnancies. There was no difference in clinical pregnancy rate (28.9% vs 28.2%, P  =.837) and live birth rate (17.3% vs 21.4%, P  =.201) between the ID and CD groups. Spontaneous abortion rate was significantly lower in the CD group than in the ID group (37.2% vs 23.0%, P  =.041). There was no difference in obstetrical outcomes., Conclusions: It was considered that the simple CD regimen may be more beneficial than the complicated ID regimen., Competing Interests: Tatsuyuki Ogawa, Tsuyoshi Kasai, Maki Ogi, Jiro Fukushima, and Shuji Hirata declare that they have no conflicts of interest., (© 2021 The Authors.

Objective: To present a case of pediatric cholesteatoma that invaded the petrous apex (PA) and discuss the usefulness of preoperative three-dimensional (3D) surgical simulation on a personal computer (PC) and patient-specific 3D printed model-assisted surgery., Patient: A 5-year-old boy with congenital cholesteatoma underwent a planned two-stage canal wall up mastoidectomy. The cholesteatoma had invaded the PA from a small space anterior to the superior semicircular canal (SSCC). During the removal of this lesion in the first surgery, the tip of a 1-mm round knife broke off and fell into the PA. The surgeon could not remove it, as it was thought that opening the space might damage the SSCC and the facial nerve (FN)., Intervention: Before the second surgery, a preoperative 3D surgical simulation on a PC was performed, and an approach to the PA via the triangle surrounded by the SSCC, FN, and middle cranial fossa, namely, the supracochlear approach, was discovered. A patient-specific 3D-printed model, which had been drilled to make each surface of the triangle including the SSCC, FN, and middle cranial fossa visible in the PC simulation surgery, was then created and a 3D-printed model-assisted surgery was planned., Results: By placing the sterilized patient-specific 3D model close to the surgical field, the cholesteatoma and iatrogenic foreign body could be successfully removed from the PA without damaging the important surrounding structures., Conclusions: Preoperative 3D surgical simulations and intraoperative patient-specific 3D-printed model-assisted surgeries are new, powerful tools that aid in performing challenging surgeries on temporal bones.

Between 2011 and 2018, 518 respiratory adenovirus infections were diagnosed in a pediatric clinic in Shizuoka, Japan. Detection and typing were performed by partial sequencing of both hexon- and fiber-coding regions which identified: adenovirus type 1 (Ad-1, n = 85), Ad-2 ( n = 160), Ad-3 ( n = 193), Ad-4 ( n = 18), Ad-5 ( n = 27), Ad-11 ( n = 2), Ad-54 ( n = 3), and Ad-56 ( n = 1). Considering previous reports of the circulation of an endemic recombinant Ad-2, e.g., Ad-89, 100 samples typed as Ad-2 were randomly selected for further molecular typing by sequencing the penton base-coding region. Despite the high nucleotide sequence conservation in the penton base- coding region, 27 samples showed 98% identity to Ad-2. Furthermore, 14 samples showed 97.7% identity to Ad-2 and 99.8% identity to Ad-89, while the remaining 13 samples showed an average 98% pairwise identity to other Ad-C types and clustered with Ad-5. The samples typed as Ad-89 ( n = 14) and as a recombinant Ad type (P5H2F2) ( n = 13) represented 27% of cases originally diagnosed as Ad-2, and were detected sporadically. Therefore, two previously uncharacterized types in Japan, Ad-89 and a recombinant Ad-C, were shown to circulate in children. This study creates a precedent to evaluate the epidemiology and divergence among Ad-C types by comprehensively considering the type classification of adenoviruses., Competing Interests: The authors declare no conflict of interest.

Humans can recall various aspects of a characteristic sound as a whole when they see a visual shape stimulus that has been intimately associated with the sound. In subjects with audio-visual associative memory, auditory responses that code the associated sound may be induced in the auditory cortex in response to presentation of the associated visual shape stimulus. To test this possibility, mice were pre-exposed to a combination of an artificial sound mimicking a cat's "meow" and a visual shape stimulus of concentric circles or stars for more than two weeks, since such passive exposure is known to be sufficient for inducing audio-visual associative memory in mice. After the exposure, we anesthetized the mice, and presented them with the associated visual shape stimulus. We found that associative responses in the auditory cortex were induced in response to the visual stimulus. The associative auditory responses were observed when complex sounds such as "meow" were used for formation of audio-visual associative memory, but not when a pure tone was used. These results suggest that associative auditory responses in the auditory cortex represent the characteristics of the complex sound stimulus as a whole., Competing Interests: The authors have declared that no competing interests exist.

Purpose: To clarify the anatomical distribution of otosclerotic loci in otosclerosis., Methods: Ninety-five patients with surgically confirmed uni- or bilateral otosclerosis were enrolled into the study. Hypodense areas observed in the otic capsule by high-resolution computed tomography (HRCT) were defined as otosclerotic loci. The location and number of lesions were examined, and the probability of lesion overlap and correlation with age/hearing parameters (air and bone conduction threshold, air-bone gaps) were tested., Results: Otosclerotic loci were confirmed by HRCT in 77 out of 115 operated ears. The three commonly affected sites were the anterior part of the oval window (ant-OW), anterior part of the internal auditory canal (ant-IAC), and pericochlear area (PCochA), with lesions detected in 96.1%, 46.8%, and 26.0% of ears, respectively. Only the ant-OW area was affected in 48.1% of the ears; the ant-IAC in 3.9%; and PCochA in none with significant differences (p < 0.01). The ant-OW lesions preferentially overlapped with ant-IAC (44.6%) than PCochA lesions (27.0%) (p < 0.05). Among double sites diseases, triple sites diseases occurred more commonly in the ant-OW + PCochA group (80%) than ant-OW + ant-IAC group (48.5%) (p < 0.05). There was no correlation between a number of lesions and age/hearing parameters., Conclusions: Based on the probability of lesion overlap, otosclerotic lesions may initiate at ant-OW followed by ant-IAC and later PCochA. Although the number of lesions showed no immediate correlation with hearing level or age, anatomical stage of the disease estimated by the location and the number of otosclerotic loci could be useful in predicting the future hearing status.

Coxsackievirus A6 (CV-A6) is an enterovirus, which is known to cause herpangina. However, since 2009 it has frequently been isolated from children with hand, foot, and mouth disease (HFMD). In Japan, CV-A6 has been linked to HFMD outbreaks in 2011 and 2013. In this study, the full-length genome sequencing of CV-A6 strains were analyzed to identify the association with clinical manifestations. Five thousand six hundred and twelve children with suspected enterovirus infection (0-17 years old) between 1999 and 2013 in Hyogo Prefecture, Japan, were enrolled. Enterovirus infection was confirmed with reverse transcriptase-PCR in 753 children (791 samples), 127 of whom (133 samples) were positive for CV-A6 based on the direct sequencing of the VP4 region. The complete genomes of CV-A6 from 22 positive patients with different clinical manifestations were investigated. A phylogenetic analysis divided these 22 strains into two clusters based on the VP1 region; cluster I contained strains collected in 1999-2009 and mostly related to herpangina, and cluster II contained strains collected in 2011-2013 and related to HFMD outbreak. Based on the full-length polyprotein analysis, the amino acid differences between the strains in cluster I and II were 97.7 ± 0.28%. Amino acid differences were detected in 17 positions within the polyprotein. Strains collected in 1999-2009 and those in 2011-2013 were separately clustered by phylogenetic analysis based on 5'UTR and 3Dpol region, as well as VP1 region. In conclusion, HFMD outbreaks by CV-A6 were recently frequent in Japan and the accumulation of genomic change might be associated with the clinical course., (© 2017 Wiley Periodicals, Inc.)

Enterovirus D68 (EV-D68) infection is associated with upper and lower respiratory tract symptoms such as fever, cough, and wheezing. Pediatric patients with EV-D68 infection easily develop more severe respiratory complications compared to patients infected with other species of enterovirus, and consequently, have a higher rate of hospitalization and admission to intensive care units. Therefore, the clinical picture of respiratory complications associated with EV-D68 infection needs to be elucidated. Here, we report a 4-year-old girl of EV-D68 infection that required artificial respiration management within 24 h from the onset of cold symptoms. The patient was diagnosed with interstitial pneumonia on the basis of chest imaging findings with patchy, funicular and frosted glassy shadows, increased blood markers of surfactant protein-A, surfactant protein-D and sialylated carbohydrate antigen KL-6, and increased neutrophils and lymphocytes in the bronchoalveolar lavage. Steroids showed a remarkable effect in her treatment. Further investigations are needed to confirm the efficacy of steroids for interstitial pneumonia due to EV-D68 infection. As rapid deterioration of respiratory status is observed in EV-D68 infection, the possibility of interstitial pneumonia may be considered., (Copyright © 2016 Japanese Society of Chemotherapy and The Japanese Association for Infectious Diseases.

Objective: To describe a case of lateral sinus insufficiency, presumably occurring just prior to lateral sinus thrombosis (LST), and to discuss the importance of early surgical intervention and the pathophysiology of full-blown LST., Case Report: A 4-year-old boy developed headaches and vomiting after exhibiting typical symptoms of acute otitis media. Contrast-enhanced CT revealed narrowing of the sigmoid sinus medially by gas and low-density material. We diagnosed the patient with suspected LST and consequently performed mastoidectomy. A large amount of bloody pus was found in the mastoid cavity and below the bony sinus plate. Sigmoid sinus blood flow was completely restored after drainage of the hemorrhagic and purulent material, and the patient recovered fully., Conclusion: Because of the anatomical features of the dural venous sinus, hemorrhage per diapedesis may be strongly associated with the development of LST. In the patient with suspected LST, early diagnosis and surgery prior to the development of intravenous thrombus are key for full recovery from this condition., (Copyright © 2015 Elsevier Ireland Ltd.
