This article reports on evidence for the validity of major depression (MDD) with atypical features (defined as overeating and oversleeping) as a distinct subtype based on cross-sectional and 1-year prospective data from the Epidemiologic Catchment Area study. MDD with atypical features, when compared to MDD without atypical features, was associated with a younger age of onset, more psychomotor slowing, and more comorbid panic disorder, drug abuse or dependence, and somatization disorder. These differences could not be explained by differences in demographic characteristics or by symptom severity. This study, based on a community sample, found that major depression with atypical features may constitute a distinct subtype.

In evaluating a large group of foster children from biological families with a high incidence of alcohol and/or drug abuse, there emerges a subsample of children with both atypical eating patterns as well as atypical behavior patterns. Their physical and behavioral characteristics are described. These children are neither obese nor "failure to thrive." They display an excessive appetite for food, a driven quality to their eating, an apparent lack of satiety, and frequent eating to the point of vomiting or gastric pain if food intake is not limited externally. All of these children have psychiatric disorders. Hyperphagia appears to be a marker for significant psychopathology.

Little attention has been given to the role of tobacco dependence within alcohol and drug abuse treatment. Yet, smoking behavior appears to be interrelated with the use of alcohol and other drugs. This interrelationship is explored, and the role of smoking cessation within alcohol and drug abuse treatment is considered. Areas for future research on this topic are identified. Addictive disorders are generally thought to include alcohol abuse, drug abuse, smoking, overeating, and, sometimes, gambling and caffeine dependence. While some attention has been paid to the common etiological roots of various addictive disorders, relatively little systematic attention has been paid to commonalities in their treatment and especially to the treatment of multiple disorders in the same individuals. The one significant exception is alcohol abuse and drug abuse. Of the other addictive disorders, tobacco dependence has been most closely interrelated with alcohol and drug abuse. Yet, little attention has been given to tobacco dependence within alcohol and drug abuse treatment. This paper will focus on smoking in relationship with alcohol and drug abuse, and will consider the possible role of smoking cessation treatment within the context of alcohol and drug abuse treatment. First, background regarding the interrelationship of alcohol and drug abuse is explored. Then, the relationship of smoking with other substance use is considered, followed by a review of special concerns related to smoking among alcohol and drug abuse clients. Next, the current status of smoking cessation within alcohol and drug abuse treatment is addressed. Finally, implications are considered.

Numerous studies have estimated the frequency of bulimia nervosa among high school girls and college women, but population-based trends in incidence in a community have not been reported. In this study we determined the incidence of bulimia nervosa by identifying persons residing in the community of Rochester, Minnesota, who had the disorder initially diagnosed during the 11-year period from 1980 to 1990. Using our comprehensive population-based data resource (the Rochester Epidemiology Project), we identified cases by screening 777 medical records with diagnoses of bulimia; feeding disturbance; rumination syndrome; adverse effects of cathartics, emetics, or diuretics; polyphagia; sialosis; or vomiting. We identified 103 Rochester residents (100 female and 3 male) who fulfilled DSM-III-R diagnostic criteria for bulimia nervosa during the 11-year study period. Mean +/- S.D. age for females at the time of diagnosis was 23.0 +/- 6.1 years (range, 14.4 to 40.2 years). Yearly incidence in females rose sharply from 7.4 per 100000 population in 1980 to 49.7 in 1983, and then remained relatively constant around 30 per 100000 population. The annual age-adjusted incidence rates were 26.5 per 100000 population for females and 0.8 per 100000 population for males. The overall age- and sex-adjusted annual incidence was 13.5 per 100000 population. Bulimia nervosa is a common disorder in adolescent girls and young women from 15 to 24 years of age. Histories of alcohol or drug abuse, depression, or anorexia nervosa were higher than expected in the general population.

A case is reported of isolated native tricuspid calve Candida parapsilosis endocarditis (INTVCE) in a male patient with no history of drug abuse or heart disease. The patient had received hyperalimentation and antibiotics for four months via a central venous catheter after abdominal surgery. He underwent successful treatment with tricuspid valve debridement, liposomal amphotericin (AmBisome) and fluconazole, and remained without relapse during an eight-year follow up. A literature review of 12 similar cases (including the present patient) without history of drug abuse or heart disease, dating from 1970, is included.

Our simple definition of ethics is good thought, speak and action. Epistemology means the hypothesis of facts about thought, speech and action. Medical practice is all means of medicine. Medicine classifies people into normal and abnormal. The abnormal are the sick. They loose some organs or those normal looking organs are dysfunctional. They are social problems, some can be treated, and some do not get the appropriate care. The problems of society of normal people are overeating and obesity, abortion, drug abuse, promiscuity, torture, terrorism, disobeying rules and order, corruption, brain-washing and unethical advertisements, etc. On the other hand, the social problems of the abnormal are down, deafness, blindness, dumb, hypertension, hypercholesterolemia, diabetes mellitus and cancer, etc. An example of the social-doctor problem is the mal distribution of doctors in rural areas. It was reported by the ministry of public health that the ratio of doctor to population to be 1:800 in Bangkok and 1:5, 700 in some rural areas in the north eastern part of Thailand. The doctors, themselves, are at a high grade of worker and intelligent quotient. They know all the problem and, at the same time, create problems, both, faster than the general population can do. It affects good and bad in the society. In the past, present and the foreseeable future the medical students get their studies in the western style. Their medical schools are situated in big cities. These schools are old and famous. They learn their medical procedure in a big hospital of more than 400 beds in the inpatient department wards. Their instructors and professors are highly qualified, are middle class people and well accepted in the society. Their families are lovely and warm. Their children study in the first class schools in town. The medical students feel very happy and appreciate seeing their professors in television routinely at prime time. In conclusion, their professors are an example of role model for them to follow. Everyone looks for security in her/his profession. Facts need no proof and reference. People with justice in mind should believe and understand the above mentioned. This leads to the problem of mal distribution of doctors in rural areas, why do doctors live in big cities or wish to be in the private sector? In fact, not many a number of doctors serve in the rural area. About 4-5 of them, their name will be announced yearly as the best rural doctor award. After the big ceremony, lasted not longer than a month, it is hard to remember their name. They are proud to be praised, it pushes them into stress intentionally with all the best of their intelligence and the total of their body strength to work harder in rural. Unfortunately their earning, the security of their profession, the increased chance of being sued, to get caught in the medical litigation, the expenses of their family social status and the study of their children cannot be compared to of those doctors in big city and/or in the private sector. Mal distribution of doctors in remote rural areas has been a persisting unresolved problem in many parts of the world, why not apply the principles of ethics and epistemology? They have been left, untouched forever.

Based on the results of the clinical follow-up study of 41 female patients, diagnostic criteria of bulimia nervosa that should be used in clinical studies are suggested as follows: (1) presence of anorexia nervosa or transitory amenorrhea in the premorbid period; (2) eating attacks with losing of the control over food consumption not less than twice a week during 3 months; (3) compensatory behavior in the form of spontaneous vomiting, abuse of purgative and diuretic medications etc; (4) fear of obesity; (5) cycloid affective changes with higher impulsivity, reduction of the control over primitive drives and/or expressed anxiety disorders; inclination to alcohol and drug abuse and nicotine dependence; (6) changes of the body mass index; (7) absence of amenorrhea. The disease dynamics is characterized by formation of the pathological cycle "diet--overeating--compensatory behavior" on the background of cyclothymic affective disorders. Two types of bulimia nervosa--with and without other drive disorders--have been singled out.

As adult humans, we are continuously faced with decisions in which proper weighing of the risk involved is critical. Excessively risky or overly cautious decision making can both have disastrous real-world consequences. Weighing of risks and benefits toward decision making involves a complex neural network that includes the dorsolateral prefrontal cortex (DLPFC), but its role remains unclear. Repetitive transcranial magnetic stimulation studies have shown that disruption of the DLPFC increases risk-taking behavior. Transcranial direct current stimulation (tDCS) allows upregulation of activity in the DLPFC, and we predicted that it might promote more cautious decision making. Healthy participants received one of the following treatments while they performed the Balloon Analog Risk Task: (1) right anodal/left cathodal DLPFC tDCS, (2) left anodal/right cathodal DLPFC tDCS, or (3) sham tDCS. This experiment revealed that participants receiving either one of the bilateral DLPFC tDCS strategies adopted a risk-averse response style. In a control experiment, we tested whether unilateral DLPFC stimulation (anodal tDCS over the right or left DLPFC with the cathodal electrode over the contralateral supraorbital area) was sufficient to decrease risk-taking behaviors. This experiment showed no difference in decision-making behaviors between the groups of unilateral DLPFC stimulation and sham stimulation. These findings extend the notion that DLPFC activity is critical for adaptive decision making, possibly by suppressing riskier responses. Anodal tDCS over DLPFC by itself did not significantly change risk-taking behaviors; however, when the contralateral DLPFC was modulated with cathodal tCDS, an important decrease in risk taking was observed. Also, the induced cautious decision-making behavior was observed only when activity of both DLPFCs was modulated. The ability to modify risk-taking behavior may be translated into therapeutic interventions for disorders such as drug abuse, overeating, or pathological gambling.

Our dramatically changed food environment--since periods in our history when food sources were highly constrained--has presented new challenges for obesity research. For example, these alterations have strongly emphasized the physiological differences between the homeostatic and the hedonic regulation of food intake--the latter being largely responsible for the pronounced increase in obesity in the past few decades. There is also increasing agreement that compulsive overeating shares many parallels with addiction disorders such as drug abuse. These factors have also fostered a renewed interest in identifying individual differences in personality and motivational systems that increase the risk for overeating and weight gain in our population. Reward sensitivity has been the focus of a recent body of compelling research, with evidence favoring two seemingly opposite points of view. On the one hand, studies have found support for a link between low reward sensitivity and obesity, whereas other evidence suggests that a strong appetitive motivation leads to overeating and weight gain. Arguments are provided to reconcile these apparently disparate theories. Finally, the role of impulsivity and its links with symptoms of attention deficit/hyperactivity disorder are discussed, as well as their respective roles in the risk profile for obesity.

Historically, studies of food intake regulation started with the hypothalamus and gradually expanded to mesocorticolimbic regions, while studies of drug use began with mesocorticolimbic regions and now include the hypothalamus. As research on ingestive behavior has progressed, it has uncovered more and more similarities between the regulation of palatable food and drug intake. It has also identified specific neurochemicals involved in palatable food and drug intake. Hypothalamic orexigenic neurochemicals specifically involved in controlling fat ingestion, including galanin, enkephalin, orexin and melanin-concentrating hormone, show positive feedback with this macronutrient, with these peptides both increasing fat intake and being further stimulated by its intake. This positive relationship offers some explanation for why foods high in fat are so often overconsumed. Research in Bart Hoebel's laboratory in conjunction with our own has shown that consumption of ethanol, a drug of abuse that also contains calories, is similarly driven by these neurochemical systems involved in fat intake, consistent with evidence closely relating fat and ethanol consumption. Both fat and ethanol intake are also regulated by dopamine and acetylcholine acting in mesocorticolimbic nuclei. This close relationship of fat and ethanol is likely driven in part by circulating lipids, which are increased by fat and ethanol intake, known to increase expression and levels of the neurochemicals, and found to promote further intake of fat and ethanol. Compellingly, recent studies suggest that these systems may already be dysregulated in animals prone to consuming excess fat or ethanol, even before they have ever been exposed to these substances. Further understanding of these systems involved in consummatory behavior will allow researchers to develop effective therapies for the treatment of overeating as well as drug abuse.
