In this era of constrained health-care resources, a critical need exists for efficient, measurable systems of disease management that strike a balance between social responsibility and patient welfare.
The incidence of melanoma is rising globally despite increased awareness. Familiarity with the clinical signs and certain risk factors for melanoma can result in early recognition, and potentially influence outcome. Unfortunately, there are several other cutaneous tumors, both malignant and benign, that resemble melanoma, and may confuse and possibly delay the diagnosis. This paper discusses the clinical characteristics of melanoma and its most common pigmented simulators.
Ectopic pregnancy is an increasingly common and potentially catastrophic condition for which patients often present to the ED with abdominal pain or vaginal bleeding. Recent developments in laboratory tests (sensitive beta hCG, progesterone assays), ultrasonography (transvaginal probes, Doppler ultrasound), and combinations of these modalities (hCG Discriminatory Zone for ultrasonographic evidence of intrauterine pregnancy) have allowed the earlier diagnosis of ectopic pregnancy, with an associated reduction in maternal mortality and morbidity. Understanding the strengths and limitations of the variety of diagnostic modalities available will allow the clinician to formulate a rational strategy for the early diagnosis of ectopic pregnancy. Numerous algorithms have been developed. All begin with high clinical suspicion in women of reproductive age with abdominal/pelvic pain or vaginal bleeding. Pregnancy testing with a sensitive beta hCG qualitative test is next. In stable patients found to be pregnant, sonography generally follows, first transabdominally, then transvaginally. Unstable patients require immediate resuscitation and gynecologic consultation; invasive diagnostic methods may supplant laboratory and sonography. Unclear cases may require the use of quantitative beta hCG (discriminatory zone), other pregnancy hormone (progesterone) testing, invasive procedures (laparoscopy, culdocentesis, D & C), or observation (serial beta hCG). A suggested algorithm incorporating these elements is presented (Figure 2).
Medical care is becoming more technically challenging and community-based. The majority of patients and family health gatekeepers (the family member who regulates health care services for the family unit) are female, while the majority of physicians are male. Therefore, differences in female versus male methods of decision making add to the difficulty in making health choices. The female patient and family health gatekeeper may need new knowledge, skills and time to help them deal with difficult medical choices. They may benefit from a multidisciplinary, unbiased group of experts in the form of a Community Healthcare Committee. Trained to be responsible for the general health of the community, the primary care practitioner is ideal to take a leadership role in developing such a committee. A Community Healthcare Committee that understands different methods of health decision making could serve as a resource by providing community health education and private case reviews intended to help individuals with health care decisions.
