Prolonged vitamin C deficiency can result in numerous metabolic abnormalities like impaired tissue repair and defective collagen synthesis. This case report describes a middle-age Japanese man presenting painful purpura on his lower limbs, severe anemia, and altered consciousness. The patient had been eating a selective diet lacking in vegetables and fruits since childhood. A serum analysis demonstrated a low level of vitamin C. The patient was treated with vitamin supplementation and psychological intervention. Scurvy is an under-considered illness with a favorable prognosis if diagnosed early while it is still sporadically encountered in some patients with malabsorption or malnutrition even in modern times.

Background: Cochineal dye is used worldwide as a red coloring in foods, drinks, cosmetics, quasi-drugs, and drugs. The main component of the red color is carminic acid (CA). Carmine is an aluminum- or calcium-chelated product of CA. CA and carmine usually contain contaminating proteins, including a 38-kDa protein thought to be the primary allergen. Severe allergic reactions manifest as anaphylaxis. The aim of this study was to review all Japanese reported cases and propose useful diagnostic chart.Methods: All reported Japanese cases of cochineal dye-induced immediate allergy were reviewed, and newly registered cases were examined by skin prick test (SPT) with cochineal extract (CE) and measurement of CE and carmine-specific serum IgE test. Two-dimensional (2D) western blotting using patient serum was conducted to identify the antigen.Results: Twenty-two Japanese cases have been reported. SPT and the level of specific IgE test indicated that six cases should be newly registered as cochineal dye allergy. All cases were adult females, and all cases except three involved anaphylaxis; 13 cases involved past history of local symptoms associated with cosmetics use. Japanese strawberry juice and fish-meat sausage, and European processed foods (especially macarons made in France) and drinks were recent major sources of allergen. 2D western blotting showed that patient IgE reacted to the 38-kDa protein and other proteins. Serum from healthy controls also weakly reacted with these proteins.Conclusions: SPT with CE and determination of the level of CE and carmine-specific IgE test are useful methods for the diagnosis of cochineal dye allergy.

Pharmaceutical consultation targeting outpatients at the Fujita Health University Hospital (Japan) provides support to patients undergoing anticancer drug treatment. This study aimed to explore factors that affect the comprehension of cancer chemotherapy among outpatients who received cancer treatment at our hospital. A questionnaire survey was conducted, and comprehension was scored on a scale of 1–5 (1, no comprehension; 5, full comprehension). When factors other than age and sex [the influence of which on comprehension has been reported in previous reports] were noted, differences in comprehension between the questionnaire items were comparatively analyzed according to the presence/absence of the relevant factors. Overall, 536 patients were included. Age (<70 years) and pharmacist interventions were identified as factors contributing to a comprehension score. The levels of comprehension regarding the name of the cancer chemotherapy, content/schedule of the treatment, purposes of the prescribed drugs, and objectives of blood tests were significantly higher in the group that received the pharmaceutical interventions; conversely, the level of comprehension for the self-management of adverse events was significantly lower in this group than in the group that did not receive any pharmaceutical interventions. Age and interventions by the pharmacist affected the comprehension of cancer chemotherapy by patients.

Purpose: Deep learning reconstruction (DLR) has been recommended as useful for improving image quality. Moreover, compressed sensing (CS) or DLR has been proposed as useful for improving temporal resolution and image quality on MR sequences in different body fields. However, there have been no reports regarding the utility of DLR for image quality and T-factor assessment improvements on T2-weighted imaging (T2WI), short inversion time (TI) inversion recovery (STIR) imaging, and unenhanced- and contrast-enhanced (CE) 3D fast spoiled gradient echo (GRE) imaging with and without CS in comparison with thin-section multidetector-row CT (MDCT) for non-small cell lung cancer (NSCLC) patients. The purpose of this study was to determine the utility of DLR for improving image quality and the appropriate sequence for T-category assessment for NSCLC patients.Methods: As subjects for this study, 213 pathologically diagnosed NSCLC patients who underwent thin-section MDCT and MR imaging as well as T-factor diagnosis were retrospectively enrolled. SNR of each tumor was calculated and compared by paired t-test for each sequence with and without DLR. T-factor for each patient was assessed with thin-section MDCT and all MR sequences, and the accuracy for T-factor diagnosis was compared among all sequences and thin-section CT by means of McNemar’s test.Results: SNRs of T2WI, STIR imaging, unenhanced thin-section Quick 3D imaging, and CE-thin-section Quick 3D imaging with DLR were significantly higher than SNRs of those without DLR (P < 0.05). Diagnostic accuracy of STIR imaging and CE-thick- or thin-section Quick 3D imaging was significantly higher than that of thin-section CT, T2WI, and unenhanced thick- or thin-section Quick 3D imaging (P < 0.05).Conclusion: DLR is thus considered useful for image quality improvement on MR imaging. STIR imaging and CE-Quick 3D imaging with or without CS were validated as appropriate MR sequences for T-factor evaluation in NSCLC patients.

The invasion of the yellow fever mosquito <i>Aedes aegypti</i> at Narita International Airport, Japan was detected for the first time. During the course of routine vector surveillance at Narita International Airport, 27 <i>Ae. aegypti</i> adults emerged from larvae and pupae collected from a single larvitrap placed near No. 88 spot at passenger terminal 2 on August 8, 2012. After the appearance of <i>Ae. aegypti</i> in the larvitrap, we defined a 400-m buffer zone and started an intensive vector survey using an additional 34 larvitraps and 15 CO₂ traps. International aircraft and passenger terminal 2 were also inspected, and one <i>Ae. aegypti</i> male was collected from the cargo space of an international aircraft from Darwin via Manila on August 28, 2012. Larvicide treatment with 1.5% fenitrothion was conducted in 64 catch basins and one ditch in the 400-m buffer zone. Twenty-four large water tanks were also treated at least once with 0.5% pyriproxyfen, an insect growth regulator. No <i>Ae. aegypti</i> eggs or adults were found during the 1-month intensive vector survey after finding larvae and pupae in the larvitrap. We concluded that <i>Ae. aegypti</i> had failed to establish a population at Narita International Airport.
