Over the last two decades, drug and alcohol abuse by pregnant women has spread to epidemic proportions. Maternal drug abuse has neurobehavioral and somatic effects which may be long-lasting and devastating to the offspring. Opiates, such as heroin and pain killers that contain a narcotic component, are widely abused today. A prominent manifestation of fetal exposure to these drugs is the neonatal withdrawal syndrome, which typically includes wakefulness, jitteriness and other symptoms of cerebral irritability. These, in turn, may interrupt early mother-infant interaction, affecting the infant's long-term emotional and cognitive development. Fetal cocaine exposure may cause neonatal cerebral irritability, changes in habituation responses, reduced head circumference, poor mental development and long-lasting impairment of the brain. Benzodiazepines can cause fetal dysmorphism (including microcephaly), neurological and behavioral impairments and neonatal withdrawal symptoms. Maternal use of amphetamines may cause neonatal dysphoria and agitation, as well as long-term lassitude and drowsiness that may result in poor feeding. Fetal exposure to alcohol may cause neonatal withdrawal symptoms, maladaptive behavior in childhood and the fetal alcohol syndrome (including microcephaly). Maternal alcohol consumption is also a common cause of mental retardation. Fetal exposure to marijuana may delay maturation of the visual system and impair memory and verbal performance at 2 years of age. The inevitable conclusion is that society must seek ways not only to treat, but also to prevent this epidemic. To this end, a key factor would be to identify potential drug abusing mothers before they reach the stage of prenatal care and educate them regarding the fatal consequences of drug abuse.

A 68-year-old woman, presented with a squamous cell carcinoma of the malar region, and underwent wide local excision. During her clinical examination, repetitive protrusion and intrusion of the tongue as well as stereotypic, abnormal movements of the mouth and lips were observed, in a pattern that resembled chewing, sucking or lip pursing; dyskinesias ceased when she was speaking or bringing food to the mouth. She was unaware of the movements and the tongue was observed to move similar to choreiform movements, while revealing a giant "snake-like" macroglossia. She had history of mental retardation and alcohol abuse, and was under classic antipsychotic medications for several years. During a previous neurological investigation, type I Chiari malformation was diagnosed. In this case, concomitant Chiari malformation and neuroleptic-induced tardive dyskinesia, may together have been responsible for giant macroglossia, and to our best knowledege no similar observation has been reported in the literature.

Objective: Body mass index undergoes a substantial change in some psychiatric disorders. This study aimed to explore the status of body mass index (BMI) in different psychiatric disorders in a national survey among children and adolescents and to identify the role of gender in this regard. Method : A total of 30 532 children and adolescents were randomly selected using cluster sampling method with equal blocks of three age groups and two genders. Psychiatric disorders were assessed using a standardized face-to-face diagnostic interview of Kiddie Schedule for Affective Disorders and Schizophrenia-Present and Lifetime Version (KSADS-PL), and Body Mass Index (BMI) was measured for each participant. Results: In this study, 22 730 children and adolescents (109 46 boys and 11784 girls), with valid data of BMI, completed the KSADS-PL interview. The prevalence of psychiatric disorders was 21.2% among underweight participants, 22.8% among overweight participants, and 22.2% among obese participants, which was significantly higher than normal weight participants with 19.6% (X2 = 17.55; p = 0.001). In boys' subgroup, depression and separation anxiety were mostly seen among the underweight category, while tic disorder was mostly seen in the obese category. In girls' subgroup, on the other hand, generalized anxiety was mostly observed in the underweight category, while oppositional defiant disorder (ODD), depression, and mental retardation were mostly observed in the obese category. In total, the highest mean BMI rates were among the children and adolescents with alcohol abuse disorder, mania, and panic disorder. However, the lowest BMI rates were among those with attention deficit hyperactivity disorder (ADHD), separation anxiety disorder (SAD), and enuresis. Conclusion: This study gives an overall picture of BMI status in different psychiatric disorders according to gender. Furthermore, in a multidisciplinary approach, the results of this study drew the attention of child psychiatrists to the status of BMI in their clients.
