Prompt [[Prompt::A 5-year-old boy is brought to the emergency department by his mother for difficulty breathing and cyanosis. Physical examination reveals cyanotic extremities and bounding jugular venous pulsations. Initial imaging reveals the cardiac anomaly shown below. Upon further investigation, the mother admits that she received several medications during her pregnancy and did not receive any prenatal care. The physician suspects a medication-induced congenital abnormality. The patient's mother has most likely received medications during pregnancy for which disorder?

]]

Answer A AnswerA::Several mild episodes of increased impulsivity, rapid speech, and insomnia for at least 2 years
Answer A Explanation [[AnswerAExp::Cyclothymia is a mild form of bipolar that lasts for at least 2 years. Psychotherapy is the optimal management approach for patients with cyclothemia.]]
Answer B AnswerB::Hypersomnia, overeating, and mood reactivity
Answer B Explanation [[AnswerBExp::Hypersomnia, overeating, and mood reactivity are the classical symptoms of atypical depression. Treatment typically involves MAO inhibitors and psychotherapy.]]
Answer C AnswerC::Alternating symptoms of depression with episodes of increased impulsivity, rapid speech, and insomnia
Answer C Explanation [[AnswerCExp::Bipolar disorder classically presents with alternating symptoms of depression and episodes of mania. Manic episodes are usually described as significant distractibility, irresponsibility, hedonistic behavior, grandiosity, racing thoughts, psychomotor agitation, insomnia, and talkativeness or pressured speech.]]
Answer D AnswerD::Recurring intrusive thoughts or sensations that cause severe distress and are relieved partly by repetitive actions
Answer D Explanation [[AnswerDExp::Compulsions that are relieved by repetitive behavior are the classical symptoms of obsessive compulsive disorder (OCD). The optimal pharmacological therapy for OCD is SSRI]]
Answer E AnswerE::Excessive and unreasonable anxiety that interferes with normal function
Answer E Explanation [[AnswerEExp::Generalized anxiety disorder (GAD) is characterized by excessive and unreasonable anxiety that interferes with normal function. The optimal The optimal pharmacological therapy for GAD is SSRI]]
Right Answer RightAnswer::C
Explanation [[Explanation::

Ebstein’s anomaly is a congenital heart disease characterized by abnormalities of the tricuspid valve, the right atrium, and the right ventricle. Apical displacement of the tricuspid valve leaflets leads to an atrialized right ventricle that is often too small to circulate sufficient blood. Ebstein's anomaly is relatively rare with an incidence of 1 in 200,000. Patients with severe forms present with cyanosis, dyspnea, and failure to thrive. The majority of these patients have early manifestation of the disease following close of the PDA and may be dependent on the PDA for pulmonary blood flow. Nonetheless, it is not uncommon that manifestations be delayed until childhood, adolescence, and even early adulthood. The development of Ebstein's anomaly has been associated with lithium administration during pregnancy particularly in the first trimester. Lithium is a mood stabilizer indicated for bipolar disorder, which is characterized by alternating symptoms of depression and episodes of mania. Manic episodes are usually described as significant distractibility, irresponsibility, hedonistic behavior, grandiosity, racing thoughts, psychomotor agitation, insomnia, and talkativeness or pressured speech.
Educational Objective: Lithium is a mood stabilizer indicated for bipolar disorder. Lithium administration during pregnancy is associated with the development of Ebstein's anomaly, especially when administered during the first trimester. Bipolar disorder classically presents with alternating symptoms of depression and episodes of mania.
