Objective: This study was conducted to describe Axis I sexual diagnoses of 60 males arrested for possession of child pornography obtained via the Internet and/or attempting to meet children via the Internet.

Methods: Data was obtained from a chart review of evaluations conducted on 60 males referred for a psychosexual evaluation following an arrest for possession of child pornography and/or attempting to meet children. All crimes involved use of the Internet. Information obtained from the chart review was entered into SAS. All diagnoses were made according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision. Simple descriptive statistics were computed and cross tabulations were tested for significance using χ2 or Fisher's Exact test.

Results: Of the total sample, 40% had at least one paraphilia. Thirty-one percent had a diagnosis of pedophilia and 18% of a paraphilia not otherwise specified (NOS). Thirty-three percent had a sexual disorder NOS, characterized by hypersexuality. Seventy percent of the total sample had an Axis I disorder that antedated and was judged to be contributory to the behavior leading to their arrest.

Conclusions: This sample of men arrested for committing crimes against children and adolescents via the Internet has a high incidence of lifetime sexual and other psychopathology.

Antidepressants have been available since the 1950s, when the monoamine oxidase inhibitors were first discovered. Since then, our armamentarium of antidepressants has progressively expanded with the discovery of the tricyclic antidepressants (TCAs) in the 1960s, the selective serotonin reuptake inhibitors (SSRIs) in the 1980s, and, subsequently, the serotonin norepinephrine reuptake inhibitors (SNRIs), and other agents possessing a diverse mechanism of action including buproprion, and mirtazapine.

The common occurrence and high level of morbidity and burden associated with social anxiety disorder (SAD) are gaining widespread recognition. Interest in understanding and treating the disorder has also grown in response to large-scale investigations that have demonstrated high levels of efficacy with both pharmacologic and nonpharmacologic treatments. Such trials indicate that many patients with generalized SAD (roughly 40% to 60%) respond (eg, Clinical Global Impressions–Improvement rating 1 or 2) after an adequate treatment trial, despite having suffered with disabling symptoms for most of their adult lives. First-line therapy options include the selective serotonin reuptake inhibitors and the dual-acting serotonin-norepinephrine reuptake inhibitor venlafaxine. Second-line options consist of anticonvulsants (gabapentin, pregabalin, valproic acid) and benzodiazepines (clonazepam). Reversible and irreversible monoamine oxidase inhibitors (moclobemide and phenelzine, respectively), while effective, are not widely used. Nonpharmacologic approaches, such as cognitive-behavioral therapy (CBT), are also effective for SAD. Newer treatment strategies such as levetiracetam, atypical antipsychotics, or D-cycloserine in combination with CBT appear promising but require further investigation. Finding a well-tolerated, safe, and effective treatment for each individual patient is crucial as most will require ongoing treatment in order to maintain benefits, prevent SAD relapse, and to experience optimal outcomes in the long term.

In medically complex patients with multiple comorbid illnesses who require concomitant medications, selecting the optimal antidepressant (ie, low risk of adverse effects and/or pharmacokinetic interactions) for an individual patient is critical for positive long-term patient outcomes. The serotonin-norepinephrine reuptake inhibitors (SNRIs) are increasingly being used as first-line treatment for major depressive disorder (MDD) and may prove beneficial for treatment of medically complex patients. Thus, it is key for clinicians to evaluate the differences in the pharmacokinetic and tolerability profiles of the SNRI class of antidepressants, evaluating differences both within the class and compared with other antidepressants used to treat MDD.

Patients with seizure of frontal lobe origin can present with bizarre behavior. At times, this bizarre behavior can be unrecognized or confused with seizure of other origin with nonepileptic events or with psychiatric disorder.

I recently saw a patient who began to experience events that were characterized by terrible fear which was followed by irritability. It was as if she could not stand in place where she was at and felt like running away. She was referred to a psychiatrist who diagnosed her to have panic disorder. She was subsequently treated for panic disorder. Her symptoms did not improve; therefore, she came to see me for a second opinion. Upon asking, the patient reported that the episodes were always the same and that they lasted approximately seconds to minutes. Due to the stereotypicity of the event and a normal routine electroencephalography (EEG), we requested that she would undergo a 24-hour video-monitoring EEG. Stereotypicity can help the physician in the differential diagnosis of psychiatric disorder versus a seizure disorder. During 24-hour video-monitoring EEG, she experienced several of these events. Also, a computer tomography scan was performed, which showed a small meningioma in the orbital frontal region.

Background: Exposure-based therapy for anxiety disorders is believed to operate on the basis of fear extinction. Studies have shown acute administration of D-cycloserine (DCS) enhances fear extinction in animals and facilitates exposure therapy in humans, but the neural mechanisms are not completely understood. To date, no study has examined neural effects of acute DCS in anxiety-disordered populations.

Methods: Two hours prior to functional magnetic resonance imaging scanning, 23 spider-phobic and 23 non-phobic participants were randomized to receive DCS 100 mg or placebo. During scanning, participants viewed spider, butterfly, and Gaussian-blurred baseline images in a block-design paradigm. Diagnostic and treatment groups were compared regarding differential activations to spider versus butterfly stimuli.

Results: In the phobic group, DCS enhanced prefrontal (PFC), dorsal anterior cingulate (ACC), and insula activations. For controls, DCS enhanced ventral ACC and caudate activations. There was a positive correlation between lateral PFC and amygdala activation for the placebo-phobic group. Reported distress during symptom provocation was correlated with amygdala activation in the placebo-phobic group and orbitofrontal cortex activation in the DCS-phobic group.

Conclusions: Results suggest that during initial phobic symptom provocation DCS enhances activation in regions involved in cognitive control and interoceptive integration, including the PFC, ACC, and insular cortices for phobic participants.

There is a growing database of research on self-help and Internet-guided interventions in the treatment of common mental disorders, and a number of meta-analyses have now been published. This article provides a systematic review of meta-analyses on the efficacy of self-help interventions, including Internet-guided therapy, for depression and anxiety disorders. Searches were conducted in PubMed, PsychINFO, EMBASE, and the Cochrane database for statistical meta-analyses of randomized, controlled trials of self-help or Internet-guided interventions for depression or anxiety disorders published in English. Reference lists were also used to find additional studies. Effect sizes were tabulated; 13 meta-analyses reported medium to large effect sizes for self-help interventions. Studies included in the meta-analyses differed in samples, type of self-help (eg, computer-aided, Internet-guided), control conditions, and study design. The meta-analyses indicate that self-help methods are effective in a range of different disorders, including depression and anxiety disorders. Most meta-analyses found relatively large effect sizes for self-help treatments, independent of the type of self-help, and comparable to effect sizes for face-to-face treatments. However, further research is needed to optimize the use of self-help methods.

Introduction: Once-daily extended release quetiapine fumarate (quetiapine XR) monotherapy was evaluated in major depressive disorder (MDD).

Method: This was an 8-week (6-week randomized-phase; 2-week drug-discontinuation/tapering phase), double-blind, parallel-group, placebo-controlled study. The primary outcome measure was Montgomery-Åsberg Depression Rating Scale (MADRS) total score randomization-to-Week 6 change. Other assessments included the Hamilton Rating Scale for Depression, the Hamilton Rating Scale for Anxiety, and adverse events (AEs).

Results: 723 patients were randomized: 182, 178, 179, and 184 to quetiapine XR 50, 150, 300 mg/day, and placebo, respectively. At Week 6, significant reductions occurred in MADRS score with quetiapine XR 50 mg/day (−13.56; P<.05), 150 mg/day (−14.50; P<.01) and 300 mg/day (−14.18; P<.01) versus placebo (−11.07); at Day 4, reductions for quetiapine XR (titrated to 50 or 150 mg/day according to dose group) versus placebo (−2.9) were: −4.7 (P<.01), −5.2 (P<.001), and −5.1 (P<.001), respectively. At endpoint, MADRS response (≥50% reduction in score) was 42.7% (P<.01), 51.2% (P<.001), and 44.9% (P≤.001) for quetiapine XR 50, 150, and 300 mg/day, respectively; 30.3% for placebo. Overall, quetiapine XR 150 mg/day provided consistently more positive secondary efficacy results than 50 mg/day and 300 mg/day versus placebo. The most common AEs in quetiapine XR-treated patients were dry mouth, sedation, somnolence, headache, and dizziness.

Conclusion: In patients with MDD, quetiapine XR monotherapy (50/150/300 mg/day) is effective in reducing depressive symptoms, with improvement from Day 4 onwards. Safety and tolerability were consistent with the known profile of quetiapine.

Emotional difficulties, such as anxiety and depression, are common after acquired brain injury in adults and can influence long-term outcome. Diagnosis in a brain injury context can be difficult. Ideally, rehabilitation approaches should consider the specific treatment of anxiety and depression as well and may include pharmacotherapy, individual psychotherapy, and family interventions. Psychotherapy, especially in regards to longer-term adjustment to brain injury, may have an important adjunctive role in treatment approaches, but adaptations of techniques may be needed. A clinical pathway is described which can help to raise clinicians' awareness, as well as increase detection rates and consideration of the specific role of individual psychotherapy in this clinical population. However, an important caveat is that clinical pathways should not serve as a substitute, but rather a facilitator, for the process of reasoning about individual patients in everyday clinical practice.

Dyke-Davidoff-Masson syndrome, or cerebral hemiatrophy, is a pre- or perinatally acquired entity characterized by predominantly neurologic symptoms, such as seizures, facial asymmetry, contralateral hemiplegia, and mental retardation. Psychiatric symptoms are rarely reported. We report the first case of left cerebral hemiatrophy and a late onset of treatment-resistant schizoaffective disorder after a stressful life event. The patient finally responded well to clozapine. The clinical history and results from structural neuroimaging are highlighted to discuss the possible developmental bias for psychotic disorders.

Basic animal studies and human imaging studies have contributed to our understanding of the psychobiology of love and attachment. There are overlaps and distinctions in the neuronal circuitry of maternal love, romantic love, and long-term attachment. In these circuits, important molecules, which have been demonstrated to play a role in the psychobiology of social bonding include dopamine, serotonin, opioids, oxytocin, and vasopressin. Particular genetic and environmental variations contribute to social-bonding phenotypes, consistent with an evolutionary perspective on the value of these behaviors. Advances in the psychobiology of social bonds have led to hypotheses about the pharmacotherapy of disorders of attachment.
