Taking the edge off: why patients choose St. John's Wort.

BACKGROUND: The number of visits to alternative medicine practitioners in this country is estimated at 425 million, which is more than the number of visits to allopathic primary care physicians in 1990. Patients' use of St. John's Wort (SJW) has followed this sweeping trend. The purpose of our study was to examine the reasons people choose to self-medicate with SJW instead of seeking care from a conventional health care provider. METHODS: We used open-ended interviews with key questions to elicit information. Twenty-two current users of SJW (21 women; 20 white; mean age = 45 years) in a Southern city participated. All interviews were transcribed, and descriptive participant quotes were extracted by a research assistant. Quotes were reviewed for each key question for similarities and contextual themes. RESULTS: Four dominant decision-making themes were consistently noted. These were: (1) Personal Health Care Values: subjects had a history of alternative medicine use and a belief in the need for personal control of health; (2) Mood: all SJW users reported a depressed mood and occasionally irritability, cognitive difficulties, social isolation, and hormonal mood changes; (3) Perceptions of Seriousness of Disease and Risks of Treatment: SJW users reported the self-diagnosis of "minor" depression, high risks of prescription drugs, and a perception of safety with herbal remedies; and (4) Accessibility Issues: subjects had barriers to and lack of knowledge of traditional health care providers and awareness of the ease of use and popularity of SJW. Also of note was the fact that some SJW users did not inform their primary care providers that they were taking the herb (6 of 22). Users reported moderate effectiveness and few side effects of SJW. CONCLUSIONS: SJW users report depression, ease of access to alternative medicines, and a history of exposure to and belief in the safety of herbal remedies. Users saw little benefit to providing information about SJW to primary care physicians.

Office procedures. Cryotherapy of dermal abnormalities.

Cryotherapy of dermal abnormalities is a commonly used technique in the field of primary care. To perform cryotherapy effectively, one must understand the principles of cryoablation and how they apply to specific skin disorders. One also must be familiar with the various types of equipment that are used to perform cryotherapy. With this understanding cryotherapy easily can be integrated into outpatient primary care.

Atypical glandular cells of undetermined significance and adenocarcinoma in situ: summoning colposcopic expertise?

In comparison with cervical squamous neoplasia, glandular cell neoplasia is uncommon. The evaluation of a patient with atypical glandular cells of undetermined significance is challenging because subtle colposcopic signs are frequently inaccessible to view and cytologic interpretations are extremely challenging for many cytopathologists.

EEG detection of nontonic-clonic status epilepticus in patients with altered consciousness.

Subtypes of status epilepticus (SE) without tonic-clonic convulsions (nontonic-clonic SE) present as altered consciousness sometimes with subtle motor activity and are important to consider in the differential diagnosis of patients with unexplained altered consciousness. Other patients may have altered consciousness with intermittent ictal activity on electroencephalography (EEG) that represents probable SE, but have other medical conditions that may be contributing to altered consciousness. EEG is the only reliable way to make the diagnosis of nontonic-clonic SE and we make emergency EEG available on a 24-h basis at our hospital. To determine how often definite or probable nontonic-clonic SE was detected by EEG we prospectively collected data on all cases where physicians ordered EEG to evaluate altered consciousness or possible SE. Out of 198 cases with altered consciousness but no clinical convulsions, 74 (37%) showed EEG and clinical evidence of definite or probable nontonic-clonic SE. Forty-two episodes (57%) were probable or definite complex partial SE, 29 (39%) were probable or definite subtle generalized SE, and three (4%) were myoclonic SE. In 23 SE cases altered consciousness was the only clinical sign at the time of diagnosis; subtle motor activity was present in 36 others. Neither clinical signs nor prior history predicted which patients showed SE on EEG. Nontonic-clonic SE followed a cerebral infarction in 16 cases. Contrary to other reports, we found no relationship between duration of SE and EEG pattern. Subtle generalized SE occurred most commonly in the setting of a diffuse brain injury rather than evolving from convulsive SE. This study demonstrates that nontonic-clonic SE is a common finding in patients with unexplained altered consciousness and EEG is necessary in the evaluation of these patients.
