We surveyed seven teenagers who gave birth without visiting antenatal clinics. Although six of the seven had been aware that they were pregnant, they had not felt able to talk with their parents about their pregnancies.

Reactive oxygen species (ROS) are produced from molecular oxygen. ROS are the reduced forms of molecular oxygen and have high reactivity to biological components e.g. lipid, protein, and nucleic acid. ROS are considered to cause various diseases e.g. arteriosclerosis, myocardial infarction, cancer, and so on. A living body protects against ROS by antioxidant enzymes e.g. superoxide dismutase (SOD) and catalase. Natural antioxidants e.g. ascorbic acid (vitamin C) and α-tocopherol (vitamin E) also scavenge ROS. Recently, some novel artificial antioxidants are synthesized and are expected to a lead compound for drugs.

Anisakiasis is a disease characterized by the abrupt onset of sharp epigastric pain, typically a few hours after eating raw or undercooked seafood. At present, the most common effective treatment is endoscopic removal. However, over 23 years Yamamoto has used an antiallergic drug (Stronger Neo-Minophagen C) and prednisolone to treat more than 190 patients with anisakiasis diagnosed on the basis of symptoms and without endoscopy. In this report, Kurihara reconfirms the effectiveness of this unique treatment for patients with endoscopically diagnosed anisakiasis. On the basis of these findings, we propose that the combination therapy of an antiallergic drug and a corticosteroid is a reasonable, inexpensive, and safe method for treating anisakiasis.

Drug-induced hypersensitivity syndrome (DIHS) is a rare but severe disease associated with multiorgan failure. The association of DIHS with human herpes virus 6 (HHV-6) has recently been reported. We report on an 89-year-old woman with allopurinol-induced DIHS diagnosed on the basis of symptoms and laboratory examinations. A rash appeared as erythema on the trunk and extremities and edematous erythema on the face. Renal dysfunction, leukocytosis, eosinophilia, and atypical lymphocytes were also present. An elevated titer of antibodies against HHV-6 and HHV-6 DNA in the blood were observed during the course of the disease (1 : 20 to 1 : 1280). Discontinuation of allopurinol administration and systemic corticosteroid treatment led to an improvement, but symptoms worsened when the corticosteroid dosage was tapered. An elevated titer of antibodies against cytomegalovirus was detected during the course of the disease. The patient died of pneumonia, most likely related to cytomegalovirus. This case indicates that, in addition to the reactivation of HHV-6, reactivation of cytomegalovirus may modify clinical disease activity.

Aquaporins are membrane water channel proteins through which water permeates the lipid bilayer. So far 13 aquaporin isoforms, aquaporin-0 (AQP0) to AQP12, have been identified in mammals. They are classified into 3 subgroups: 1) aquaporins that selectively transfer water, 2) aquaglyceroporins that transfer some small solutes as well as water, and 3) unorthodox aquaporins. They are widely distributed in most water-handling organs, such as kidney, and play important roles in water transfer. For example, segment-specific expression of AQP1, AQP2, AQP3, AQP4, AQP6, AQP7, and AQP11 in the renal tubular epithelium enables water reabsorption to produce concentrated urine. Aquaporins are usually localized to the plasma membrane. Some isoforms, such as AQP2, are present in the intracellular membrane compartment. AQP2 in collecting duct cells translocates between intracellular vesicles and the cell surface via a membrane trafficking mechanism. Mutations of AQP2 result in congenital nephrogenic diabetes insipidus. This review summarizes the distribution and physiological importance of aquaporins, with a special focus on the kidney.

Atopic dermatitis (AD) is the most common chronic and relapsing inflammatory skin disease. Both abnormal barrier function and abnormal immune function are closely involved in the etiology of AD. Patients with AD have been subdivided into abnormal filaggrin, normal filaggrin, high immunoglobulin E, normal IgE groups, and so on. Regarding local cytokine profiles in the skin of patients with AD, the involvement of Th2, Th22, and Th17 cells at the acute stage, and the involvement of Th2, Th22, and Th1 cells at the chronic stage have been suggested. The IL-9 level has been reported to be higher in patients with AD than in healthy individuals, but it has also been reported that there are no differences in IL-9 levels between patients with AD and normal individuals. Thus, the role of IL-9 is unclear. The serum IL-18 level is high and induces Th2 reactions in patients with AD. IL-21 is thought to suppress IgE formation, but its activity in relation to AD remains unknown. IL-22 is involved in hyperplasia, increased antimicrobial peptide formation, and reduced filaggrin in patients with AD. IL-25, IL-33, and thymic stromal lymphopoietin are produced in epidermal cells and activate type 2 innate lymphoid cells or premature dendritic cells, resulting in the induction of Th2 reactions. IL-31 is produced by Th2 cells, causing an itching sensation and scratching behavior. A correlation has been reported between serum IL-32 levels and the severity of dermatitis. IL-34 is an element of the control system that suppresses inflammation, but its activity in cases of AD is unknown. One published report describes a correlation between serum IL-37 levels and the severity of dermatitis, but this relationship has not been sufficiently clarified to date, and requires further analysis. In this review, the author has attempted to summarize reports on cytokine expression in patients with AD. The author expects that important cytokines and cells involved in the pathophysiology of AD will be revealed, contributing to strategies for treating AD.

The association between cerebrovascular diseases and depression has been recognized for many years. Studies have found much information about the pathogenesis and treatment of post-stroke depression in the West since the 1970s. On the other hand, the concept of vascular depression was introduced in 1997, as the prevalence of silent cerebral infarctions detected by MRI scans in patients with late-onset depression is higher than that in non-depressed patients. This paper gives an outline of the clinical findings about vascular depression including post-stroke depression.

Histochemistry, especially immunohistochemistry, is a powerful and diverse set of methods for obtaining spatial and temporal information concerning the expression and distribution of biomolecules in situ. In this technical note, we describe procedures for fixation and immunofluorescence microscopy using cryostat sections.

Over 190,000 patients die each year in japan due to ischemic heart disease. For these patients, percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG) are done to improve the blood flow of coronary artery with stenosis. It would be better to prevent or mitigate the progress of atherosclerosis in these patients before requiring surgery. Recently, it has been reported that epicardial adipose tissue plays an important role in the progression of atherosclerosis and ischemic heart disease.This review shows the recent trends about ischemic heart disease from the clinical perspective, including its' treatment, pathology and preventive measure.

Viral vectors are powerful tools for gene delivery and expression both in vitro and in vivo. Recently, many types of viral vectors have become commercially available and are easily used. It is important to choose appropriate viral vectors according to target cells and organs. In this technical note, we describe the characteristics of viral vectors and how to choose the appropriate viral vector to transduce target cells in vitro.

The neuroendocrine system of the hypothalamus is involved with the regulation of pituitary hormone secretion and with feeding, sexual behavior, stress response, and circadian rhythm. The neuronal networks for the regulation of feeding, sexual behavior, and stress responses communicate with and influence each other in a complex manner. This paper presents an overview of the interaction of these neuroendocrine systems, particularly from of the point of view of the mechanism of the onset of puberty.

Several psychological and behavioral treatments have been gaining attention recently for their effectiveness in improving common diseases, such as depression and anxiety. Cognitive behavioral therapy (CBT) is particularly notable in this context, as considerable evidence of its efficacy has been presented. In this paper, we introduce the basic concept of CBT and offer evidence of its effectiveness. We believe that CBT is an effective intervention and hope that it will become widely used to deal with patient distress.
