ABSTRACT: A thorough history and physical examination can establish the diagnosis of tension headache; further evaluation is generally unnecessary. In contrast, the workup of cervicogenic headache includes standard radiographs, 3-dimensional CT, MRI, and possibly electromyography; nerve blocks may also be used to confirm the diagnosis. Episodic tension headache can be treated effectively by trigger avoidance, behavioral modalities, and structured use of analgesics. Reserve opioids for patients with intractable headaches. Chronic tension headache is treated primarily by prophylactic measures, such as antidepressants and anticonvulsants, and behavioral and physical therapy. Treatment options for cervicogenic headache include analgesics; invasive procedures, such as trigger point injections, greater or lesser occipital nerve blocks, facet joint blocks, segmental nerve root blocks, and diskography; spinal manipulation; and behavioral approaches.

Actinomyces odontolyticus isa rare cause of pleuropericardialinfection, with only 1 caseidentified in the literature. Inthat instance, the infectionwas believed to be secondaryto gastric surgery. We present apatient with pericarditis andpericardial tamponade causedby A odontolyticus. The infectionoccurred after an ultrasound-guided subcarinalbronchoscopic needle biopsyperformed for a suspicious mediastinalmass found on a CTscan of the chest. We describethe case presentation, the microbiologyand treatment of Aodontolyticus infection, andthe classic features of pericarditisand cardiac tamponade.

For 6 months, a 19-year-old woman had had sensitivity to cold. When outside in cold weather, she noticed swelling, erythema, and pruritus of her uncovered hands. After she held a cold drink on her arm for about 5 minutes, urticarial lesions developed on the skin in contact with the drink. The symptoms resolved about 20 minutes after the cold source was removed. She denied angioedema, respiratory symptoms, light-headedness, and tachycardia.

The patient was a 41-year-old manwith a history of HIV infection diagnosed10 years before admission.He had been noncompliant withtreatment, and therapy with tenofovir,efavirenz, and lamivudinehad not been started until 2 monthsbefore admission, when he presentedto another hospital. At thetime, his CD4+ cell count was156/µL and his viral load was45,743 copies/mL. He also had ahistory of incarceration; had usedinjection drugs, cocaine, alcohol,and marijuana; and had a 20-packyeartobacco history.

The major causes of chronic cough include upper airwaycough syndrome (UACS, formerly known as postnasal dripsyndrome), asthma, nonasthmatic eosinophilic bronchitis, andgastroesophageal reflux disease. In fact, one or more of these isthe cause of cough in the vast majority of nonsmokers who arenot receiving angiotensin-converting enzyme inhibitors andwho have no evidence of active disease on chest radiographs. Ahigh index of suspicion is required, because each of these conditionsmay present with cough as the sole symptom. BecauseUACS may be the most common cause, it appears reasonableto try empiric UACS therapy in patients in whom other causesare not evident at initial evaluation. In many cases, the combinationof a first-generation antihistamine and a decongestantmay be most effective. (J Respir Dis. 2008;29(3):113-122)

ABSTRACT: Education can help improve compliance with inhaled corticosteroid therapy or correct faulty metered-dose inhaler (MDI) technique. Options for patients with poor MDI technique include use of a spacer or an alternative device, such as a nebulizer or a dry powder inhaler. If therapy is ineffective, consider alternative conditions that mimic asthma, especially vocal cord dysfunction and upper airway obstruction. Treatment of comorbid conditions, such as gastroesophageal reflux disease or rhinosinusitis, may improve control. In refractory asthma, it is crucial to identify allergic triggers and reduce exposure to allergens. If another medication needs to be added to the inhaled corticosteroid, consider a long- acting b-agonist, leukotriene modifier, or the recombinant monoclonal anti-IgE antibody omalizumab.

A 38-year-old man found lying on the floor in his home was hospitalized because of alcohol intoxication. A chest radiograph showed a large calcified lesion in the left upper abdomen. A CT scan with intravenous contrast revealed a large, well-defined, cystic mass with mural calcification in the spleen. The CT findings were not consistent with a vascular malformation or echinococcal cyst-specifically, the mass was sharply demarcated, unilocular without septations, and round with a thin wall and attenuation similar to water. Urine Histoplasma antigen test results were negative.

Cumulative research with animal, normative, and clinical populations over several decades shows that the mechanisms underlying anxiety disorders differ from those of the normal emotion of anxiety. In persons with anxiety disorders, fear and tension are disproportionate to the actual threat and may be present when no real threat exists, thereby generating an expectation of danger and distorted perceptions related to danger and various types of threats. The most common anxiety disorders are social anxiety disorder (SAD), generalized anxiety disorder (GAD), and posttraumatic stress disorder (PTSD). Persons with SAD can experience a wide range of social fears as well as severe functional consequences, whereas persons with GAD tend to experience emotional, interpersonal, and somatic symptoms of high levels of chronic anxiety. Persons with PTSD have vivid memories of and thoughts about a terrifying event or ordeal that lead to the development of anxiety, depression, and functional impairment. Effective treatment options-pharmacotherapy; psychotherapy, particularly cognitive-behavioral therapy; or a combination-can be discussed openly with the patient to make a collaborative, informed decision. A variety of medications can be used to successfully manage anxiety disorders, of which SSRIs and serotonin-norepinephrine reuptake inhibitors are the most effective. When properly used, medications can enhance a patient's own efforts to master anxiety; overcome fearful avoidance; and address troubling behaviors, patterns, or memories.
