Thus, our attention should shift from the concern of potential adverse effects to the health benefits imparted by hormonal contraceptives. The use of oral contraceptives for at least 12 months reduces the risk of developing endometrial cancer by 50%. Furthermore, the risk of epithelial ovarian cancer in users of oral contraceptives is reduced by 40% compared with that on nonusers. This kind of protection is already seen after as little as 3-6 months of use. Oral contraceptives also decrease the incidence of ovarian cysts and fibrocystic breast disease. They reduce menstrual blood loss and thus the incidence of iron-deficiency anemia. A decreased incidence of pelvic inflammatory disease and ectopic pregnancies has been reported as well as an ameliorating effect on the clinical course of endometriosis.

Tetanus is a disease caused by the release of neurotoxins from the anaerobic, spore-forming rod Clostridium tetani. The clostridial protein, tetanus toxin, possesses a protease activity which selectively degrades the pre-synaptic vesicle protein synaptobrevin, resulting in a block of glycine and y-aminobutyric acid (GABA) release from presynaptic terminals. Consistent with the loss of neurogenic motor inhibition, symptoms of tetanus include muscular rigidity and hyperreflexia. The clinical course is characterized by increased muscle tone and spasms, which first affect the masseter muscle and the muscles of the throat, neck and shoulders. Death occurs by respiratory failure or heart failure.

Patients in the more aggressive categories are less likely to exhibit involvement of the skin and have a less favorable prognosis [10]. Those patients may have a definable hematological disorder such as a myelodysplastic syndrome, myeloproliferative disorder, acute leukemia, or a malignant lymphoma. In aggressive mastocytosis and mast cell leukemia, the clinical course is determined by the rapidity of the increase in mast cell numbers. 

AIA runs a characteristic clinical course [9]. It is more frequent in women than men, and is unusual in children, beginning in adulthood, on average at the age of 30 years. Rhinorrhea and nasal congestion are usually the first symptoms, subsequently complicated by polyposis. Asthma and aspirin hypersensitivity develop 2-15 years later. Once developed, aspirin intolerance remains through life, although sporadic disappearance of intolerance has been reported. Asthma, characterized by blood and nasal eosinophilia, rims a protracted course despite avoidance of analgesics. In about half the patients, the course of asthma is severe, necessitating use of systemic corticosteroids.

LD isoenzyme abnormality does not precede the appearance of the (mb) in the serum following myocardial infarction. The reappearance of (mb) is interpreted as diagnostic of reinfarction, and correlates with new electrocardiographic changes and an altered clinical course.

Infective endocarditis caused by these streptococci typically has a subacute clinical course. The current cure rate is often over 90% unless complications occur, which is the case in more than 30% of patients.17 The majority of viridans streptococci remain very susceptible to penicillin, with most strains having a minimum inhibitory concentration (MIC) of less than 0.125 mcg/mL.15,18 Organisms with decreased susceptibilities are increasing. Therefore, antibiotic susceptibilities need to be assessed in order to determine the most appropriate treatment regimen.

The treatment aim for patients with aggressive histologies is cure of the malignancy. There are some histologic subtypes that exhibit an aggressive clinical course that are not considered to be curable. These patients are still treated with curative-intent chemotherapy or may be considered for a clinical trial.
