Navigating Adolescence With A Chronic Health Condition: A Perspective On The Psychological Effects Of Hair-An Syndrome On Adolescent Girls, Kimberly K. Mcclanahan, Hatim A. Omar Oct 2006

Navigating Adolescence With A Chronic Health Condition: A Perspective On The Psychological Effects Of Hair-An Syndrome On Adolescent Girls, Kimberly K. Mcclanahan, Hatim A. Omar

Pediatrics Faculty Publications

HAIR-AN syndrome is a subphenotype of polycystic ovary syndrome and is characterized by acne, obesity, hirsutism, and acanthosis nigricans. It usually manifests in early adolescence, a time of significant developmental change in females across physical, cognitive, social, and emotional domains. We contend that adolescent development for females is difficult, even in the best of circumstances, and having a chronic health condition, like HAIR-AN syndrome, will likely impact the afflicted individual's development and psychological well-being. While many researchers have discussed the long-term health effects of HAIR-AN and similar disorders, little has been written about the potential psychological sequelae of HAIR-AN on …

Pregnancy during adolescence represents a challenge to society as a whole. Its incidence is increasing and brings about social and medical consequences to both the teen mothers and their children. The purpose of this study was to evaluate pregnant teenager involvement in sexual activity and the social context. The group studied comprised 152 pregnant teenagers attending the Department of Pediatrics, Santa Casa de Sao Paulo (SCSP) General Hospital. All information was analyzed. The age at first intercourse was 14.2 years and the average period between first intercourse and pregnancy was 1.4 years. Most pregnancies (75%) were neither planned nor wanted, …

Dissociation Of Automatic And Strategic Lexical-Semantics: Functional Magnetic Resonance Imaging Evidence For Differing Roles Of Multiple Frontotemporal Regions, Brian T. Gold, David A. Balota, Sara J. Jones, David K. Powell, Charles D. Smith, Anders H. Andersen

Neuroscience Faculty Publications

Behavioral research has demonstrated three major components of the lexical-semantic processing system: automatic activation of semantic representations, strategic retrieval of semantic representations, and inhibition of competitors. However, these component processes are inherently conflated in explicit lexical-semantic decision tasks typically used in functional magnetic resonance imaging (fMRI) research. Here, we combine the logic of behavioral priming studies and the neurophysiological phenomenon of fMRI priming to dissociate the neural bases of automatic and strategic lexical-semantic processes across a series of three studies. A single lexical decision task was used in all studies, with stimulus onset asynchrony or linguistic relationship between prime and …


Biomolecular Study Of The Correlation Between Papillomatosis Of The Vulvar Vestibule In Adolescents And Human Papillomavirus, Geni Beznos, Verônica Coates, Jose Focchi, Hatim A. Omar Jun 2006

Biomolecular Study Of The Correlation Between Papillomatosis Of The Vulvar Vestibule In Adolescents And Human Papillomavirus, Geni Beznos, Verônica Coates, Jose Focchi, Hatim A. Omar

Pediatrics Faculty Publications

The main goal of this study was to investigate, through a biomolecular study, the correlation between papillomatosis of the vulvar vestibule and human papillomavirus (HPV) infection, as well as to establish the necessity of treatment. A total of 44 female adolescents between 12 and 18 years of age were selected through a prospective study with a confirmed diagnosis of papillomatosis of the vulvar vestibule. Vulvar biopsies were obtained for the histological and biomolecular detection of HPV DNA through polymerase chain reaction (PCR). Twenty (45%) adolescents were virgins (group A), the other 24 (55%) were sexually active. The virgin adolescents (group …

A Pilot Study: Attention Deficit Hyperactivity Disorder, Sensation Seeking, And Pubertal Changes, Catherine A. Martin, Greg Guenthner, Christopher Bingcang, W. Jackson Smith, Thomas E. Curry, Hatim A. Omar, Mary Kay Rayens, Tom H. Kelly

Pediatrics Faculty Publications

This study was designed to examine the relationship of pubertal changes and sensation seeking (SS) in adolescents with Attention Deficit Hyperactivity Disorder (ADHD). Patients with current or past histories of uncomplicated stimulant medication use for ADHD between the ages of 11 and 15 (13 ± 1.5) were recruited from a Child Psychiatry and a General Pediatric Clinic. SS was measured using the SS Scale for Children. Pubertal development was measured using Tanner staging, free testosterone, and DHEAS. Subjects and their parent were interviewed with the Diagnostic Interview Schedule for Children (DISC). SS total score was correlated with Tanner stage, free …

Depression, Sensation Seeking, And Maternal Smoking As Predictors Of Adolescent Cigarette Smoking, Judy Van De Venne, Kay Bradford, Catherine A. Martin, Megan Cox, Hatim A. Omar

Family Sciences Faculty Publications

The purpose of this study was to examine maternal and adolescent depression, maternal and teen sensation seeking, and maternal smoking, and their associations with adolescent smoking. Data were collected from a sample of 47 male and 66 female adolescents (ages 11-18 years) and their mothers from three different health clinics. The findings indicated that maternal sensation seeking was linked indirectly with adolescent smoking through teen sensation seeking, both of which were significantly associated with teen smoking (β = 0.29, p < 0.001 and β = 0.32, p < 0.001, respectively). Teen depression was associated positively with teen smoking (β = 0.24, p < 0.01) when controlling for sensation seeking behaviors. Maternal smoking was also directly linked to adolescent smoking (β = 0.20, p < 0.05). These findings underscore a potentially important role of sensation seeking in the origins of adolescent smoking, and clarify pathways of influence with regard to maternal attitudes and behaviors in subsequent teenage nicotine use.


Incidence Of Galactorrhea In Young Women Using Depot-Medroxyprogesterone Acetate, Hatim A. Omar, Rana M. Zakharia, Shibani Kanungo, Marlene B. Huff, Kimberly K. Mcclanahan May 2006

Incidence Of Galactorrhea In Young Women Using Depot-Medroxyprogesterone Acetate, Hatim A. Omar, Rana M. Zakharia, Shibani Kanungo, Marlene B. Huff, Kimberly K. Mcclanahan

Pediatrics Faculty Publications

Galactorrhea is rarely mentioned as a possible side effect of the use of Depot-Medroxyprogesterone Acetate (DMPA). Over the last few years, we have noticed an increased number of patients complaining of galactorrhea. A review of clinical data showed that between 1999 and 2005, 360 adolescents in our clinic used DMPA for at least 6 months. After medical follow-up, 13 (3.6%) of these patients were found to have developed galactorrhea. The mean age of the patients was 19.4 years with a range from 13-24. Prolactin levels in these patients were normal, and in all subjects, the galactorrhea resolved spontaneously within the …


Spontaneous Intracranial Arterial Dissection In The Young: Diagnosis By Ct Angiography, William C. Robertson, Curtis A. Given Apr 2006

Spontaneous Intracranial Arterial Dissection In The Young: Diagnosis By Ct Angiography, William C. Robertson, Curtis A. Given

Neurology Faculty Publications

BACKGROUND: Spontaneous carotid artery dissections have been rarely reported in children. Diagnosis has traditionally been confirmed by catheter arteriography. More recently diagnosis has been made by magnetic resonance imaging and magnetic resonance angiography; however the sensitivity of these techniques has yet to be determined. The authors are unaware of reports of carotid dissection confirmed by dynamic computed tomography (computerized tomographic arteriography) in the young.

CASE PRESENTATION: We recently evaluated a fourteen year-old male following the development of transient neurologic symptoms. There was no antecedent illness or trauma. Dynamic computed tomography revealed an intracranial dissection involving the supraclinoid segment of the …

Successful Treatment Of Depot Medroxyprogesterone Acetate-Related Vaginal Bleeding Improves Continuation Rates In Adolescents, Kristin M. Rager, Amy Fowler, Hatim A. Omar

Pediatrics Faculty Publications

High discontinuation rates for depot medroxyprogesterone acetate (DMPA) in adolescents may contribute to the number of unintended pregnancies. Many cite vaginal bleeding as a reason for discontinuing DMPA use. In this study, we attempted to determine if treating DMPA-associated vaginal bleeding with monophasic oral contraceptive pills (OCP) raised continuation rates. A total of 131 patients who reported vaginal bleeding while on DMPA were included in this study and 83 were treated with monophasic OCP. Of those who received OCP, 38.7% reported that vaginal bleeding stopped completely, 51.8% reported that vaginal bleeding stopped temporarily, and 6.0% reported no change. Overall, 94% …
