“Oral malodor (halitosis or bad breath) might be an important motivation tool for improving oral health in adolescents. There are few studies that report the epidemiology of oral malodor in high school students and the relationships with lifestyle and oral health status. This research was conducted to obtain underlying data for introducing an oral health education program which targeted prevention of oral malodor as a motivation tool for changing oral health behavior in high school students. METHODS: A questionnaire, school oral examination, and oral malodor measurement were conducted on senior high school students in a Tokyo metropolitan school in 2007. A total of 474 students (male: 219, female: 255) were used for the analysis. (more…)

Exposure to parental verbal abuse is associated with increased gray matter volume in superior temporal gyrus.

“OBJECTIVE: Exposure to parental verbal aggression (PVA) during childhood increases risk for the development of psychopathology, particularly mood and anxiety disorders. Other forms of childhood abuse have been found to be associated with alterations in brain structure. The aim of this study was to ascertain whether exposure to PVA was associated with discernible effects on brain morphology… (more…)

Is Love Passion an Addictive Disorder?

“Aims: Inquiry regarding the relationship between passionate love and addiction has long been a topic of intense debate. Recent advances in neurobiology now allow for an examination between these two states. Methods: After describing the clinical distinctions between “love passion,” “love addiction,” and “sex addiction,” we compare clinical, neuropsychological, neurobiological, and neuroimaging data on love, passion, pathological gambling (PG) and substance dependence.

The acute effects of alcohol on auditory thresholds.

“BACKGROUND: There is very little knowledge about alcohol-induced hearing loss. Alcohol consumption and tolerance to loud noise is a well observed phenomenon as seen in the Western world where parties get noisier by the hour as the evening matures. This leads to increase in the referrals to the “hearing aid clinic” and the diagnosis of “cocktail party deafness” which may not necessarily be only due to presbyacusis or noise-induced hearing loss. METHODS: 30 healthy volunteers were recruited for this trial which took place in a controlled acoustic environment. Each of the individuals was required to consume a pre-set amount of alcohol and the hearing was tested (using full pure tone audiogram) pre- and post- alcohol consumption over a broad range of 6 frequencies. Volunteers who achieve a minimum breath alcohol threshold level of 30 u/l had to have second audiogram testing. All the volunteers underwent timed psychometric and visuo-spatial skills tests to detect the effect of alcohol on the decision-making and psychomotor co-ordination. (more…)

Coitus as Revealed by Ultrasound in One Volunteer Couple.

“The anatomy and function of the G-spot remain highly controversial. Ultrasound studies of the clitoral complex during intercourse have been conducted to gain insight into the role of the clitoris and its relation to vagina and urethra during arousal and penetration. Aim. Our task was to visualize the anterior vaginal wall and its relationship to the clitoris during intercourse. Methods. The ultrasound was performed during coitus of a volunteer couple with the Voluson(R) General Electric(R) Sonography system (Zipf, Austria) and a 12-MHz flat probe. (more…)

“Sleepwalkers have been described to be involved in complex motor activities like cooking, eating, driving a car, playing an instrument, stabbing and murder [1]. We describe a case of a 44-year-old woman with idiopathic insomnia almost all her life. She tried various medications, psychotherapy and behavioral techniques for the treatment of her insomnia without any significant effects. She was started on Zolpidem 10 mg 4 years ago. She was able to sleep 4–5 h each night, but then the effects started wearing off. She increased the dose of Zolpidem by herself to 15 mg every night; she would take 10 mg tablet around 10 p.m. and 5 mg around 3 a.m. With this regimen she started sleeping for 5 h every night and felt alert during the daytime. After increasing the dose, she began to have episodes of sleepwalking. During one such episode, she went to bed around 10 p.m., she woke up 2 h later, and walked to the next room on the same floor. She turned on the computer and connected to the internet. She logged in by typing her user ID and password to her email account. She sent three emails to her friend inviting her to come over for dinner and drinks (Fig. 1A and B). (more…)

The “doctor game” revisited: doctor’s treatment of their own children.

“Although it is generally believed that doctors do not treat their own children, the practice is commonplace. This paper presents the unconscious reasons for the discrepancy between this popular belief and actual practice. The effects of this intrusion on the usual parent-child relationship are discussed. Except in emergency, the doctor’s decision to take his own child as a patient is explained as a partial reenactment of the doctor’s childhood “doctor game,” now shared and acted out in cooperation with his spouse.

“This work seeks to understand young adults’ motives for online gaming and extends previous research concerning social interaction in virtual contexts. The focus of the study is on Counter-Strike and World of Warcraft. (more…)

Proposal of alternative mechanism responsible for the function of high-speed swimsuits.

“Since many top swimmers wearing Speedo LZR Racer swimsuits have broken world records, it is considered that the corset-like grip of suit supports the swimmers to maintain flexibility of movement and reducing water resistance. We propose an alternative mechanism to explain this phenomenon. The suits are so tight that the blood circulation of swimmers is suppressed. (more…)

Determination of Human Penile Electrical Resistance and Implication on Safety for Electrosurgery of Penis.

“Electrosurgery has been a surgical application since the late 19th century. Although many urologists take this daily application for granted, the effects of electrical treatment on penile nerves and vessels have not been well documented. Aim. To investigate the electrical characteristics of the penis and erectile tissues and to discover the potential hazards of electrosurgery on the penis. (more…)
