Hepatic and Splenic Infarction in Systemic Lupus ErythematosusSystemic lupus erythematosus (SLE) was diagnosed in an 18-year-old man who presented with polyarthritis, fever, hypoxia, fatigue, anemia, neutropenia, and abnormal urinary sediment. A renal biopsy showed diffuse mesangial proliferative glomerulonephritis (World Health Organization class II). Serologic tests were positive for fluorescent antinuclear antibody (FANA), SS-A, SS-B, anti-Sm and anti-dsDNA antibodies, and rheumatoid factor; a direct Coombs' test result was positive as well.

Exercise intolerance in severe COPD: A review of assessment and treatmentAbstract: Exercise intolerance is common in persons with chronic obstructive pulmonary disease and can result from multiple physiologic factors, including dynamic hyperinflation, gas exchange abnormalities, and pulmonary hypertension. In the initial assessment, keep in mind that many patients underestimate the degree of their impairment. The 6-minute walk test is very useful in assessing the degree of exercise intolerance; when more extensive assessment is indicated, cardiopulmonary exercise testing (CPET) is the gold standard. CPET is particularly useful for defining the underlying physiology of exercise limitation and may reveal other causes of dyspnea, such as myocardial ischemia or pulmonary hypertension. Strategies for improving exercise tolerance range from the use of bronchodilators and supplemental oxygen to participation in a pulmonary rehabilitation program. (J Respir Dis. 2006;27(5):208-218)

Pulmonary arterial hypertension: Classification, diagnosis, and prognosisAbstract: Our understanding of the pathobiology of pulmonary arterial hypertension (PAH) has evolved considerably over the past 2 decades, with increasing recognition of the important role that aberrant vasoproliferative responses play in conjunction with disordered vasoconstriction. Classification of the many forms of PAH into categories sharing a similar pathophysiology and clinical presentations help the practicing clinician approach a complex differential diagnosis. Noninvasive tests can be used to narrow this differential but must be applied with an appreciation for their limitations. Transthoracic echocardiography is the screening tool of choice; the workup should also include chest radiography and electrocardiography. However, right heart catheterization is ultimately required to establish the diagnosis. While PAH remains a progressive and generally fatal disease, existing therapies have a significant impact on survival and new therapeutic targets offer great hope for improving the prognosis.

Further Evidence That HTLV Protects Against HIV ProgressionPrevious case reports have suggested an association betweenhuman T-cell lymphotropic virus (HTLV) types 1 and 2infection and chronic nonprogressive HIV infection. Evidenceis lacking about the specifics of how the two are related. Wereport 2 cases of chronic nonprogressive HIV infection (of9 and 13 years' duration, respectively) in women in whomHTLV coinfection was diagnosed. These cases provide clinicalsupport that HTLV coinfection may serve as a protective factoragainst progression of HIV infection. Possible reasons for thisrelationship and potential future research are discussed.[Infect Med. 2008;25:416-420]

Parkinson Disease: REFERENCES: EVIDENCE-BASED MEDICINE: RELEVANT GUIDELINES:ABSTRACT: Signs that strongly suggest Parkinson disease (PD) include unilateral hand tremor, slowed or decreased movement, and gait changes. Postural alterations include leaning forward or asymmetric shoulder height; the arm may not swing when the patient walks, or it may be held flexed at the elbow. Patients may report increasing difficulties in occupational and social functioning. Mimics of PD include essential tremor, normal pressure hydrocephalus, other neurodegenerative diseases, and drug-induced parkinsonism. Most patients report such nonmotor symptoms as sleep disturbances, visual difficulties, bowel and bladder problems, fatigue, depression, and anxiety. Cognitive impairment in many patients takes the form of slowing of memory and difficulty with visual spatial tasks and executive function. A more realistic treatment goal than tremor eradication is improved overall mobility.

Fever With Bacteremia in Children:ABSTRACT: Occult bacteremia now occurs in only 1 of 200 children who present with acute fever (temperature of 39°C [102.2°F] or higher) and white blood cell counts of 15,000/µL or more. The most likely cause of bacteremia remains Streptococcus pneumoniae; when there is no evidence of toxicity, such bacteremia is generally a benign, self-limited event. Because of the extremely low yield, blood cultures are no longer routinely warranted in children aged 3 to 36 months who have no obvious source of infection, and empiric treatment of occult bacteremia is no longer appropriate. Almost all cases will spontaneously resolve with a low rate of subsequent focal infection. If a child remains febrile and worsens clinically, further diagnostic evaluation and possible empiric treatment with antibiotics pending results of cultures may be considered.
