Polycystic Ovary Syndrome: Update on When to Suspect

Polycystic ovary syndrome (PCOS) is the most common endocrinopathy among reproductive-aged women; the prevalence is 5% to 10%.1 Like women with PCOS, affected adolescents often present with irregular menses, hirsutism, and acne. However, despite widespread agreement that the metabolic derangements of PCOS arise during puberty, the condition is diagnosed more often in adults than in adolescents.

Pneumococcal Pneumonia Presenting as New-Onset Seizure

A febrile 65-year-old woman who had suffered a new-onset seizure was brought to the emergency department. The patient-a cigarette smoker-was not coughing and had neither chest pain nor a significant medical history. Her temperature was 39.4°C (103°F). She had nuchal rigidity and Kernig's and Brudzinski's signs of meningeal irritation. Lung auscultation revealed signs of right middle lung consolidation. Her white blood cell count was 1,200/µL. A chest film, seen here, showed a masslike density in the right midlung.

Spontaneous Embolization of a Thrombus-in-Transit

Chest pain and dyspnea of acute onset prompted a 49-year-old man to seek urgent medical attention. Two months earlier, he had sustained fractures to the right arm and both ankles after a 25-ft fall. Ten days before presentation, the patient’s rehabilitation physician had discontinued daily enoxaparin because of improved mobility and a presumed decreased risk of thromboembolism.

Benzocaine-induced methemoglobinemia in bronchoscopy

Benzocaine-induced methemoglobinemia has been a well-documented illness that is usually simple to cure but can be life-threatening if not recognized. As the use of "scope" procedures becomes more commonplace, the early recognition of hypoxemia resulting from methemoglobinemia is essential. The authors report a case of benzocaine-related methemoglobinemia following bronchoscopy.

Acute hypoxemic respiratory failure as a manifestation of urinothorax

In the case described here, hypoxemic respiratory failure occurred secondary to a right-sided pleural effusion associated with an obstructive uropathy. The patient, a 75-year-old man with a history of benign prostatic hypertrophy (BPH), presented with a gradual onset of shortness of breath, tachypnea, and oliguria. Renal ultrasonography and CT scanning revealed bilateral hydronephrosis. A right thoracentesis yielded fluid with characteristics consistent with urinothorax. The patient was given medication for BPH, taught how to do self-straight catheterization, and scheduled for an outpatient cystoscopy. At follow-up, his chest radiograph showed no effusions.

Managing COPD, part 2: Acute exacerbations

Abstract: The standard therapies for acute exacerbations of chronic obstructive pulmonary disease include short-acting bronchodilators, supplemental oxygen, and systemic corticosteroids. For most patients, an oxygen saturation goal of 90% or greater is appropriate. Bilevel positive airway pressure (BiPAP) is usually beneficial in patients with progressive respiratory acidosis, impending respiratory failure, or markedly increased work of breathing. However, BiPAP should not be used in patients with respiratory failure associated with severe pneumonia, acute respiratory distress syndrome, or sepsis. Systemic corticosteroids are appropriate for moderate to severe acute exacerbations; many experts recommend relatively low doses of prednisone (30 to 40 mg) for 7 to 14 days. Antibiotic therapy is controversial, but evidence supports the use of antibiotics in patients who have at least 2 of the following symptoms: increased dyspnea, increased sputum production, and sputum purulence.

Using ultrasonography in the diagnosis and management of pleural disease

ABSTRACT: The increasing availability of bedside ultrasonographyallows for more timely diagnosis and treatment of pleuraleffusion while limiting the patient's exposure to radiation. Thedynamic signs characteristic of pleural effusions includerespirophasic changes in the shape of the fluid collection, floatingmovements of atelectatic lung, and the plankton sign. Ultrasonographyalso is an efficient means of excluding pneumothoraxwhen rapid diagnosis is needed or after interventionssuch as central line placement, lung or pleural biopsy, or thoracentesis.The diagnosis of a pneumothorax relies on the absenceof dynamic signs such as "lung sliding." Static signs, suchas the comet tail artifact, or consolidated lung parenchyma orlung tissue that contains a solid mass, also can be useful in excludingpneumothorax. Ultrasonography can be used to guidefine-needle aspiration and core biopsies of pleural nodules,pleural thickening, and subpleural lung masses. (J Respir Dis.2008;29(5):200-207)
