In addition purchase 250 mg flagyl otc, it takes less time to obtain a TEE using a portable device than to move a patient to an angiography suite discount flagyl 400mg fast delivery. Further testing of the patient in Question 59 reveals that he has a type B aortic dissection buy flagyl 200 mg with mastercard. He has no neurologic symptoms and his renal function is normal generic flagyl 250mg with amex. What would you recommend for this patient at this time? Aggressive treatment of hypertension with beta blockers 1 CARDIOVASCULAR MEDICINE 35 ❏ C. Aggressive treatment of hypertension with vasodilators ❏ D. Surgical repair of aneurysm with Dacron prosthesis ❏ E. Surgical repair with endoprosthesis Key Concept/Objective: To understand the treatment of type B aortic aneurysms Emergency surgery is crucial for patients with type A aortic dissections. Most such cases are managed medically by means of aggressive blood pressure control with beta blockers. If blood pressure is not adequately controlled after beta-blocker treatment, then vasodilators can be added to the beta blockers. Vasodilators should not be used in place of beta blockers. Surgery for type B dissection is indicated pre- dominantly for patients with life-threatening complications requiring a surgical approach. Such conditions include ischemia of both kidneys, leading to reversible renal failure; the development of ischemic bowel; or ischemia involving an extremity. A 67-year-old man with type 2 diabetes and a long history of cigarette smoking develops severe exer- tional chest pain. Twenty-four hours later, he devel- ops abdominal pain, painful toes, and a rash. On examination, he has purple discoloration of the sec- ond and fourth toes on his right foot and a lacy rash on both legs. Laboratory results are as follows: Hb, 13; HCT, 39; WBC, 9. Abdominal aortic aneurysmal rupture Key Concept/Objective: To be able to recognize atheromatous emboli syndrome This patient experienced the onset of abdominal pain, purple toes, and livedo reticularis shortly after undergoing cardiac catheterization. These symptoms are consistent with atheromatous emboli syndrome. The patient also has renal insufficiency, a common fea- ture of the syndrome. Contrast nephropathy is common in patients with diabetes, but that condition would not account for the cutaneous findings. Aortic dissection and rupture could cause abdominal pain and renal insufficiency, but that should not cause livedo retic- ularis or purple toes. The abdominal pain this patient experienced was most likely the result of pancreatitis caused by atheromatous emboli. A 24-year-old man presents to the emergency department complaining of chest pain. He reports having substernal chest pain of 2 days’ duration. The pain is worse with inspiration and is alleviated by main- taining an upright position. His medical history and physi- cal examination are unremarkable. An ECG shows 2 mm elevation of the ST segment in precordial leads, without reciprocal changes and with concomitant PR segment depression. What is the most likely diagnosis and the most appropriate treatment approach for this patient? Acute pericarditis; start a nonsteroidal anti-inflammatory drug (NSAID) ❏ B.

Patients who have recurrent seizures should be treated with AEDs 250 mg flagyl amex. Treatment with AEDs should follow certain basic principles 400mg flagyl mastercard. Seizure control should be achieved buy flagyl 200mg low price, if possible cheap flagyl 250 mg free shipping, by increasing the dosage of this agent. If seizure control cannot be achieved with the first medication, an alternative agent should be considered. Monotherapy can control seizures in about 60% of 34 BOARD REVIEW the patients with newly diagnosed epilepsy. The use of two or more AEDs should be avoid- ed if possible, but drug combinations may be useful when monotherapy fails. Drug selec- tion should be guided by the patient’s seizure type and epilepsy syndrome classification in concert with the mechanisms of action and side effects. Changes in dosage should be guid- ed by the patient’s clinical response rather than by drug levels; inadequate seizure control indicates the need for increasing the dose, and toxicity indicates the need to lower the dosage. Monitoring of levels is usually not necessary for patients who tolerate their med- ication well and have adequate seizure control. In some circumstances, the monitoring of drug levels may be useful in determining prescription compliance or to explain changes in seizure control or drug toxicity. This patient’s seizures are adequately controlled, and there are no clinical symptoms or signs of toxicity; therefore, changes in the dosage are not indicated, and phenytoin levels should not be followed. A 48-year-old man presents to your clinic complaining of excessive daytime somnolence. They have slowly progressed to the point where he falls asleep frequently throughout the day. The patient also reports having early morning headaches. He has tried taking naps during the day, without relief of his somnolence. His physical examination is significant for obesity and hypertension. Which of the following tests would provide the most helpful information for the diagnosis and treat- ment of this patient? Magnetic resonance imaging of the brain Key Concept/Objective: To understand the tests used to evaluate sleep disorders The two most important laboratory tests for sleep disorders are the all-night PSG study and the MSLT. This patient’s presentation is consistent with obstructive sleep apnea syndrome (OSAS); the best diagnostic test for OSAS is PSG, because it provides both diagnostic and therapeutic information. The all-night PSG study simultaneously records several physio- logic variables by use of electroencephalography (EEG), electromyography (EMG), electro- oculography (EOG), electrocardiography, airflow at the nose and mouth, respiratory effort, and oxygen saturation. Such studies are important in confirming a diagnosis of excessive daytime somnolence (EDS) or OSAS, and they also document the severity of sleep apnea, hypoxemia, and sleep fragmentation. Overnight PSG determines the optimal pressure for continuous positive airway pressure (CPAP)—a treatment for OSAS—and is also helpful for supporting the diagnosis of narcolepsy and the parasomnias. Overnight PSG with simul- taneous video recording can confirm rapid eye movement (REM) sleep behavior disorder and is particularly useful for the documentation of unusual movements and behavior dur- ing nighttime sleep in patients with parasomnias and nocturnal seizures. The MSLT is essential in documenting pathologic sleepiness (sleep-onset latency of less than 5 minutes) and in diagnosing narcolepsy; the presence of two sleep-onset REMs with four or five naps and pathologic sleepiness strongly suggest narcolepsy. Another important laboratory test for assessing sleep disorders is actigraphy. This technique utilizes an actigraph worn on the wrist or ankle to record acceleration or deceleration of body movements, which indirect- ly indicates sleep-wakefulness. Actigraphy employed for days or weeks is a useful labora- tory test in patients with insomnia and circadian rhythm sleep disorders, as well as in some patients with prolonged daytime sleepiness. Actigraphy is not the test of choice for patients with suspected OSAS. Magnetic resonance imaging studies and other neuroimag- ing techniques should be performed to exclude structural neurologic lesions if indicated; MRI will not make a diagnosis of a sleep disorder, but it can detect lesions associated with sleep disorders.

His medical record describes his initial presentation of schizophrenia purchase flagyl 250mg with mastercard. For this patient 250mg flagyl for sale, which of the following statements is consistent with the clinical manifestations of schizophrenia? The patient was known to have depression and mania with associat- ed delusions B order flagyl 200 mg without prescription. The patient did not exhibit prodromal symptoms before his initial episode of acute psychosis C generic flagyl 250 mg with mastercard. Between psychotic episodes, no residual symptoms are present D. The patient had restricted affect, low drive, and a poverty of speech Key Concept/Objective: To understand the clinical manifestations of schizophrenia The diagnosis of schizophrenia should be considered in a patient who presents with hallucinations and delusions. The presence of disorganized thought and behavior increases the likelihood of schizophrenia. In the absence of other known causes of such symptoms (e. If the patient does not have a mood disorder and the psychotic symptoms are accompanied by restricted affect, low drive, and poverty of speech, the probability of schizophrenia is high. The diagnosis can be made with greatest confidence, however, on the basis of the longitudinal pattern of the disorder, which includes the occurrence of prodromal symptoms before the initial episode, residual symptoms between psychotic episodes, and psychotic episodes that cannot be attributed to mood disturbance (e. A 31-year-old woman presents to your office with a chief complaint of hearing voices. She also relates that she believes she is being watched carefully by the FBI and that your conversation with her is probably being monitored. It is clear that she has psychotic features that are consistent with schizophrenia, but you also consider other disorders that can cause psychotic symptoms. Which of the following statements regarding disorders that can cause psychotic symptoms is true? Depression and mania are not associated with psychotic features B. Schizotypal personality disorder is similar to schizophrenia in that people with this personality disorder have persistent psychotic symptoms C. Drug abuse is an uncommon cause of psychotic symptoms D. Rarely, a brain tumor or temporal lobe epilepsy may be misdiag- nosed as schizophrenia; in such cases, MRI or electroencephalogra- phy can help make the diagnosis Key Concept/Objective: To know the common disorders that can mimic schizophrenia and to know how to differentiate between them Because schizophrenia is defined as a psychotic illness with functional impairments, distinguishing schizophrenia from normalcy is usually not difficult. However, differ- entiating schizophrenia from other disorders with psychotic features can be a chal- lenge. Schizotypal personality disorder shares some of the clinical characteristics of schizophrenia, such as social and physical anhedonia, suspiciousness, magical think- ing, blunting of affect and emotional experience, and poor functioning. However, schizotypal patients do not experience overt and persistent psychotic symptoms, although rare and brief psychotic symptoms may occur. In a patient with persistent psychosis, the differential diagnosis consists mainly of affective disorders with psy- chosis, substance abuse, and delusional disorders. Psychosis that coincides with depres- sion is typically associated with such affective features as delusions of poverty or accu- 13 PSYCHIATRY 11 satory voices. Similarly, delusions of grandeur are common during manic episodes. Psychotic symptoms in affective disorders typically follow the emergence of depression or mania and fade once the affective symptoms recede. The history and toxicology screen can rule out psychosis caused by drug abuse, such as use of PCP or long-term abuse of steroids. Delusional disorder is diagnosed on the basis of nonbizarre, persist- ent, and circumscribed delusions in the absence of the other characteristics of schizo- phrenia. Rarely, neurologic conditions such as brain tumor or temporal lobe epilepsy may be misdiagnosed as schizophrenia. When such conditions are suspected, MRI and EEG can help with the diagnosis.
