Frank psychosis may develop and be manifested as compulsive-obsessive behavior hypertension numbers order toprol xl 100 mg line, phobias, and even suicide. These psychological responses to illness should be differentiated from organic brain disease, which may cause the same symptoms. Most useful in discriminating functional from organic disease are tests of cognitive function and psychological tests. Steroids may cause or help clear a psychosis; clearing of a psychosis after steroid therapy suggests that the psychosis had an organic etiology. Headaches are a frequent complaint and are usually due to stress and tension; migraine has been noted in 10 to 37% of patients. Other causes of headache include cold food, hangover, nitrites, monosodium glutamate, hunger, sinusitis, dental or eye disease, and malignancies. Seizures are said to occur in 15 to 20% of patients and include grand mal, petit mal, temporal lobe, focal, and jacksonian seizures. Seizures may reflect an old scar or an acute inflammatory episode or may be due to metabolic imbalances, uremia, hypertension, infections, tumors, head trauma, or vasculopathy. Cranial neuropathies include those affecting eye muscles, trigeminal neuralgia, facial weakness, and vertigo. Peripheral neuropathy is usually asymmetrical and mild and affects more than one nerve (mononeuritis multiplex). The eye is frequently involved by rash involving the eyelid, conjunctivitis, or keratoconjunctivitis. A characteristic finding is retinal "cotton wool" exudates (cytoid bodies), usually near the disk. They reflect a microangiopathy of retinal capillaries and localized microinfarction of the superficial nerve fiber layers of the retina.

The classic disorder has two forms: salt wasting and simple virilizing (non-salt wasting); both result in sexual ambiguity in the newborn genetic female arrhythmia joint pain toprol xl 25 mg with visa. In the salt-wasting form, which occurs in about three fourths of cases, adrenal production of aldosterone and cortisol is inadequate. Salt-wasting crises are associated with hyponatremia, hyperkalemia, and hypovolemia, with metabolic acidosis, loss of vascular tone, and in some cases, shock and death. Crises usually arise between 7 days and 2 weeks of life, after discharge from the hospital. Thus an affected first-born male who has normal genitalia is particularly at risk for a salt-wasting crisis at home. Ambiguous genitalia in a female usually prompt diagnostic procedures, thus placing females at lower risk. Salt wasting should be carefully ruled out even in newborns with mild genital ambiguity. Unlike salt wasters, simple virilizers can synthesize sufficient amounts of aldosterone for salt retention. Non-classic 21-hydroxylase deficiency, a genetic variant of the classic form, is associated with a milder enzyme defect and does not cause prenatal virilization in a genetic female. Postnatally, in children with untreated classic and non-classic 21-hydroxylase deficiency, growth accelerates in the early years but the epiphyses close prematurely, which results in a tall child but a short adult. Even when treated, most patients do not reach the height potential indicated by family height. Without treatment, males may have evidence of pseudopuberty marked by phallic growth, small testes, and precocious growth of pubic, axillary, and body hair. Untreated females may suffer from excessive androgenic symptoms such as cystic acne, menstrual/ovulatory irregularities, or polycystic ovarian syndrome (Fig. The gene encoding 21-hydroxylase is located on the short arm of chromosome 6 within the human major histocompatibility complex. Two forms of mutations observed are gene deletions, which result from chromosomal misalignment as well as unequal crossing over during meiosis, and gene conversions, which apparently involve the transfer of short sequences resident on the pseudogene to the active gene. Routine screening at random does not detect the non-classic form of 21-hydroxylase deficiency. Clinical features in 21-hydroxylase deficiency range from prenatal virilization with labial fusion to precocious adrenarche and pubertal or post-pubertal virilization.
Cruz, 38 years: Miosis, ptosis, and anhidrosis may occur if the ascending sympathetic fibers are injured below the level at which they enter the skull with the internal carotid artery.
Gnar, 21 years: Serology or isolation of the virus from brain or peripheral blood lymphocytes confirms the cause.
Potros, 42 years: Epidemic infections in American military recruit camps were a major problem before the introduction of vaccination.
Aldo, 29 years: Inhalation anthrax should be considered in patients with appropriate exposure to an animal product, as in a weaver using imported goat hair or a textile mill worker.
