Headache is very common among women of childbearing age and can be influenced by hormonal fluctuations. When pregnant women develop headache, the cause is usually tension-type headache or migraine, but headache may be a symptom of a more serious neurologic or medical condition. This article discusses the differential diagnosis and management of major causes of headache during pregnancy

Sports medicine physicians should be able to recognize and manage peripheral nerve injuries in athletes. Most often, the injury is a result of repetitive microtrauma, linking peripheral nerve injury to other musculoskeletal injuries in athletes. As with other musculoskeletal injuries, rest and a modification of the athlete's regimen often lead to clinical improvement. If the physician is uncertain about the diagnosis, if the athlete develops a rapid worsening of symptoms and signs, or if the athlete is refractory to treatment, a physician who specializes in peripheral nerve injuries should be consulted

Nine patients presented with ataxia as the primary manifestation of epidural spinal cord compression. Eight had known cancer, the ninth an epidural abscess. Lower-extremity dysmetria, gait ataxia, or both, were the only neurologic signs in five patients. An incorrect initial diagnosis led to delay in treatment and subsequent neurologic deterioration in six patients. Failure to recognize isolated, painless ataxia as the initial manifestation of spinal cord compression and appropriately treat the disorder can result in irreversible spinal cord deterioration

Intravenous drug abusers (IVDAs) represent an increasing proportion of the HIV epidemic. Forty-three IVDA's (22 HIV-negative, 21 HIV-positive) were studied using the Mattis Dementia Rating Scale (DRS). All subjects had used intravenous heroin, but reported that they were drug-free at the time of testing. HIV-positive subjects were predominantly symptomatic and were dichotomized into AIDS and non-AIDS groups. All subjects with abnormal DRS scores were HIV-positive (57% of all HIV-positives). All HIV-negative subjects had normal DRS scores while 43% of the positive group obtained such scores. The DRS reliably identifies neuropsychological impairment, and may be a useful screening tool in this population

In view of the evidence that patients with human immunodeficiency virus infection experience reactive depression and anxiety, it is important to determine whether these factors might account for some of the cognitive deficiencies observed in this group, as is often the case in psychiatric populations. An extensive battery of cognitive, personality, and attention tests was administered to 26 patients who tested positive for the human immunodeficiency virus. In this group were patients who demonstrated no symptoms, patients who had acquired immunodeficiency syndrome-related complex, and patients who had acquired immunodeficiency syndrome. Pearson Product Moment correlations were computed between scores on the three types of measures. The results of this correlational study suggest that cognitive decline in patients infected with human immunodeficiency virus is independent of mood and attentional changes
