She complains that for the past 2 days she has had muscle spasms in her hands estradiol 1mg with amex, arms, and legs. She has a medical history of cervical Hodgkin lymphoma, which was treated with radiation. On physical examination, the Trousseau sign is positive. Hypoparathyroidism secondary to radiation therapy; start PTH injec- tions B. Vitamin D deficiency secondary to poor intake and lack of sunlight; start calcitriol C. Vitamin D deficiency secondary to poor intake and lack of sunlight; start cholecalciferol D. Hypoparathyroidism secondary to radiation therapy; start calcium and calcitriol Key Concept/Objective: To understand the most common causes of hypocalcemia and its treatment Hypocalcemia is defined as a serum calcium level of less than 9 mg/dl. Hypocalcemia is most often related to disorders of the parathyroid glands. Removal of or vascular injury to the parathyroids during neck surgery can result in hypoparathyroidism, which is mani- fested by hypocalcemia, hyperphosphatemia, and inappropriately low concentrations of PTH. Autoimmune destruction of the parathyroid glands may be seen in other autoim- mune conditions, such as polyglandular syndrome type 1. Certain infiltrative diseases, such as hemochromatosis, may also adversely affect parathyroid function, as may external beam radiation to the neck. In this patient, the history of radiation to the neck suggests the possibility of hypoparathyroidism secondary to radiation injury. Despite the fact that vita- min D deficiency is common in elderly patients, serum calcium concentrations are usual- ly not severely affected thanks to compensatory increases in PTH levels. In patients with symptoms associated with hypocalcemia (e. In most patients, vita- min D should also be provided. If dietary deficiency is suspected, plain cholecalciferol is adequate.

Recovery from partial paralysis occurs in 2–6 months trusted estradiol 2 mg; complete recovery from total paralysis varies from 20%–90%. The onset is insidious and may go undiagnosed for months or years. Unilateral facial paresthesia or pain is seen occasionally early in the disease process, although most of the symptoms involve the eye. A good history—especially one that describes remissions and exacerbations of the symptoms—can raise an index of suspicion. Computed tomography, MRI, lumbar punc- ture, and evoked potentials are all part of the diagnostic workup. Cerebrovascular Accident Although it would be unusual for facial numbness to be the presenting complaint for stroke, it should be considered in the differential diagnosis. Age and past medical history are very helpful in raising the index of suspicion for CVA. A thorough physical exam and diagnostic imaging are definitive. Scalp and Face Pruritus History It would be unusual for pruritus in the head and neck to indicate anything except a skin condition/disease or infestation. If the patient is a school-age child, pediculosis is an obvi- ous choice and the child’s friends and school administrators should be questioned about recent outbreaks. You should ask about sun exposure and blistering sunburns. A history of other skin cancers in the patient or family is important to determine. Physical Examination The physical exam includes careful inspection of the head and scalp for nits or actual lice. Nits are fixed to the hair shaft and are grayish-white in appearance. Unlike the flakiness of seborrhea, nits cannot be easily dislodged. The skin of the head and face should be inspected for lesions, color changes, new or changing moles, crusting, scaling, ulceration, or bleeding, which might be indicative of cancer or psoriasis.

A 20-year-old woman comes to your office in early spring with complaints of nasal congestion buy 1mg estradiol free shipping, runny nose, and paroxysms of sneezing. She has been experiencing these symptoms for 10 days. She denies having fever, cough, myalgias, or malaise. She states that she typically experiences bouts of similar symp- toms in September and October. Her medical history includes mild intermittent asthma since childhood. The nasal mucosa appears pale and swollen, and there is clear rhinorrhea. Which of the following statements regarding this patient’s condition is false? Nasal smear is likely to show a preponderance of eosinophils B. Her symptoms are the result of the IgE-mediated release of substances such as histamine that increase epithelial permeability C. Treatment of the condition can result in improvement of coexisting asthma in certain patients D. Although daily nasal steroid sprays can alleviate symptoms, they are gen- erally not recommended because of the risk of rhinitis medicamentosa E. Immunotherapy can be employed in patients whose symptoms persist despite the avoidance of triggers and the use of pharmacotherapy Key Concept/Objective: To understand the diagnosis and treatment of allergic rhinitis Allergic rhinitis is the most common atopic disorder in children and adults in the United States.

Antibodies against Toxoplasma are rarely present in the cere- brospinal fluid of AIDS patients proven 2mg estradiol, because of their level of immuno- suppression C. During treatment for cerebral toxoplasmosis, clinical and radiologic improvement is often observed within 2 weeks after initiating therapy D. After acute treatment of cerebral toxoplasmosis, patients must remain on lifelong suppressive therapy, independent of CD4+ T cell count 104 BOARD REVIEW Key Concept/Objective: To understand the diagnosis and treatment of cerebral toxoplasmosis in AIDS patients Most cases of toxoplasmosis in patients with AIDS result from reactivation of latent Toxoplasma cysts acquired before infection with HIV; reactivation is particularly likely when the CD4+ T cell count falls below 100 cells/µl. Serum antibody tests cannot be relied on in the diagnosis of primary toxoplasmosis in patients with AIDS; antibody titers do not reach the high levels typical of immunocompetent patients with toxo- plasmosis, nor are IgM antibodies present in patients with AIDS. However, antibodies against Toxoplasma are present in the CSF in nearly two thirds of AIDS patients with cerebral toxoplasmosis, and their detection may assist in the diagnosis. With appropri- ate therapy, clinical and radiologic improvement is often observed within 1 to 2 weeks. If patients respond poorly to treatment and are seronegative or belong to population groups at high risk for tuberculosis, biopsy should be strongly considered. Patients with AIDS who have been treated for toxoplasmosis require prolonged suppressive therapy. If the CD4+ T cell count rises above 200 cells/µl for 3 months, secondary prophylaxis for toxoplasmosis can be stopped. A 37-year-old woman presents with complaints of foul-smelling, greasy diarrhea; nausea; and excessive flatulence. She states that she returned from a camping trip about 2 weeks ago. Immunologic assay detects giardial antigen in the stool. Which of the following statements about treatment and prevention of giardiasis is true? The most effective treatment is metronidazole, 250 mg three times a day for 5 days B. When drinking water comes from a potentially contaminated source, it is essential that it be heated or, preferably, boiled for at least 10 minutes C.
