BackgroundSince Japan adopted the concept of informed consent from the West, its inappropriate acquisition from patients in the Japanese clinical setting has continued, due in part to cultural aspects. Here, we discuss the current status of and contemporary issues surrounding informed consent in Japan, and how these are influenced by Japanese culture.DiscussionCurrent legal norms towards informed consent and information disclosure are obscure in Japan. For instance, physicians in Japan do not have a legal duty to inform patients of a cancer diagnosis. To gain a better understanding of these issues, we present five court decisions related to informed consent and information disclosure. We then discuss Japanese culture through reviews of published opinions and commentaries regarding how culture affects decision making and obtaining informed consent. We focus on two contemporary problems involving informed consent and relevant issues in clinical settings: the misuse of informed consent and persistence in obtaining consent. For the former issue, the phrase "informed consent" is often used to express an opportunity to disclose medical conditions and recommended treatment choices. The casual use of the expression "informed consent" likely reflects deep-rooted cultural influences. For the latter issue, physicians may try to obtain a signature by doing whatever it takes, lacking a deep understanding of important ethical principles, such as protecting human dignity, serving the patient’s best interest, and doing no harm in decision-making for patients.There is clearly a misunderstanding of the concept of informed consent and a lack of complete understanding of ethical principles among Japanese healthcare professionals. Although similar in some respects to informed consent as it originated in the United States, our review makes it clear that informed consent in Japan has clear distinguishing features.SummaryJapanese healthcare professionals should aim to understand the basic nature of informed consent, irrespective of their attitudes about individualism, liberalism, and patient self-determination. If they believe that the concept of informed consent is important and essential in Japanese clinical settings, efforts should be made to obtain informed consent in an appropriate manner.

It is well known that reduced blood flow in the scalp is a cause of alopecia. We have shown previously that the extract of Illicium anisatum increases subcutaneous blood flow in mice. In the present study, we used an organ culture system to examine whether this extract promoted hair follicle elongation. B6C3HF1 mouse vibrissae follicles were cultured in serum-free medium for 7 days at 31 degrees C. Follicles treated with water-soluble (WS) extracts of the leaves, fruits and roots of Illicium anisatum or shikimic acid grew significantly longer than controls. In contrast, ethyl acetate-soluble (AS) extracts and n-hexane-soluble (HS) extracts of the leaves, fruits and roots of the plant inhibited hair follicles and shaft growth. Fractionation of the WS fruit extract showed that the number 1 and number 2 fractions possessed hair follicle elongation activity. GC/MS analysis revealed that the number 1 fraction contained shikimic acid, and that the number 2 fraction was a mixture of many components including glycosides and polysaccharides. Reverse transcription-polymerase chain reaction analysis demonstrated that shikimic acid also induced mRNA expression of insulin-like growth factor-1, keratinocyte growth factor, and vascular endothelial growth factor in the hair follicles. These results suggest that the WS extract of Illicium anisatum promotes hair growth and may be a useful additive in hair growth products.

BackgroundA baby hatch called the “Stork’s Cradle” has been in place at Jikei Hospital in Kumamoto City, Japan, since May 10, 2007. Babyklappes were first established in Germany in 2000, and there are currently more than 90 locations. Attitudes regarding baby hatches are divided in Japan and neither opinions for nor against baby hatches have thus far been overwhelming. To consider the appropriateness of baby hatches, we present and examine the validity of each major objection to establishing baby hatches.DiscussionThere are various objections to baby hatches as follows: It violates a child’s right to know the identity of his or her biological parents by allowing anonymous birth; it neglects fulfillment of the biological parents’ basic obligation to raise their child and its very availability induces abandonment of infants; some people abuse it for very selfish reasons; it cannot save babies’ lives; the rights of one parent can be ignored if the other surrenders a child without his or her consent; it puts a baby in medical jeopardy; and it has no clear legal basis. The authors would argue that there are many plausible refutations for each objection mainly based on priority of child’s right to life, pregnant women’s vulnerability and necessity of anonymity, social responsibility to protect and raise children, differences between dropping a child off at a baby hatch and child neglect, limited function of social childcare center, inevitability of abuse by a minority of people, necessary distinction between outcomes that occur only because baby hatches exist and those that occur regardless of their existence, important local direct and upmost measures for women in trouble, and difference between ambiguous legality and illegality.SummaryWe argue that a certain number of baby hatches should continue to be established as a last resort, in a form that can maintain anonymity if the parent dropping the child off so desires. It should be supported if it is initiated with good intentions; if the maximum possible effort is made at said facility to protect the interests, rights, and safety of the child; and if no clear evidence of harm exists.
