Chemotherapy-induced nausea and vomiting (CINV) is one of the most serious adverse effects of cancer therapy. Cancer patients frequently use acid suppressants (AS) for palliation of gastrointestinal symptoms associated with malignancy and/or anticancer therapy. AS are suggested as an additional option for CINV management in several antiemetic guidelines, although their efficacy remains unknown. The aim of this study was to determine whether AS administration affects CINV incidence in cisplatin and gemcitabine treatment for biliary tract cancer. The primary endpoint was to evaluate whether AS administration was associated with the incidence of all-grade nausea in the first administration by logistic analysis. The secondary endpoints were to assess factors associated with anorexia. Prophylactic antiemetics were based on current guidelines. Nausea occurred in 34.2% of patients (grade 1, 31.7%; grade 2, 2.5%). Patients exhibiting vomiting and anorexia represented 4.2% and 39.1%, respectively, without grade 3/4 symptoms. Multivariate analysis suggested that the independent risk factors for nausea as female sex, and no- or less-alcohol drinking habit and regular narcotics administration were associated with anorexia. In contrast, AS administration was not associated with nausea and anorexia incidence (odds ratio, 95% confidence interval: 1.43, 0.64–3.23; P =0.38 for nausea, 1.62, 0.71–3.68; P =0.25 for anorexia). In conclusion, we found that AS administration is not associated with CINV incidence, and female sex is a risk factor for nausea, and non-alcohol drinking habits and regular narcotic use are factors associated with anorexia in cisplatin and gemcitabine treatment for biliary tract cancer. We should correctly administer AS depending on the patient's situation. Successful CINV management needs effective monitoring and administration of prophylactic antiemetics and counter-measure medicines for patients at risk.

Group G Streptococcus (GGS) causes toxic shock syndrome. Its incidence has been increasing in the elderly in recent years. The case is a female patient in her 60s, with rheumatoid arthritis, who developed necrotizing fasciitis in her right thigh. We administered antibacterial agents and debridement frequently at an early stage, followed by aggressive high-protein enteral nutrition and multidisciplinary treatment. During the course of treatment, the patient’s general condition temporarily deteriorated because of fecal contamination. We considered amputation of the lower limb and implantation of a stoma, but finally succeeded in preserving the limb by performing two skin grafts. The patient was able to walk and was discharged on day 66. GGS infection is a risk factor for elderly patients with underlying diseases such as malignancy or immunocompromised states. When necrotizing fasciitis due to fulminant streptococcal infection develops in a proximal limb, amputation of the limb is often necessary to save the patient’s life. In this case, a fulminant GGS infection developed in an immunocompromised patient with active rheumatoid arthritis. Although the risk of limb amputation was high, multidisciplinary treatment enabled functional preservation of the affected limb.

Background: Sensory differences are related to the autistic traits, and previous studies have shown a positive correlation between sensory differences and internalizing problems. In this study, we hypothesized that sensory differences and suffering due to sensory differences mediates the relationships between autistic traits and internalizing problems. Methods: A total of 346 female Japanese university students completed questionnaires regarding their autistic traits, suffering due to sensory differences, and internalizing problems. Moreover, 114 participants completed a questionnaire related to sensory differences.Results: Autistic traits were correlated with Low Registration and Sensation Avoiding. These sensory differences were also correlated with suffering due to sensory differences and internalizing problems. Moreover, path analysis indicated that the higher the suffering due to Low Registration and Sensation Avoiding was, the greater the internalizing problems in those who showed these sensory differences.Conclusions: Female university students with serious suffering due to sensory differences may need support in managing their suffering and internalizing problems. Further research will help suggest support that these people require, at school and elsewhere.
