An epidemiologic study observes increased numbers of respiratory tract infections among children living in a community in which most families are at the poverty level. The infectious agents include Streptococcus pneumoniae, Haemophi lus influenzae, and Klebsiella pneumoniae. Most of the children have had pneumonitis and rubeola infection. The study documents increased rates of keratomalacia, urinary tract calculi, and generalized papular dermatosis in these children as they reach adulthood. These children are most likely to have a deficiency of

A 52-year-old woman with a long history of ethanol abuse has had increasing congestive heart failure for the past year. For the past month, she has experienced increasing con fusion, disorientation, and difficulty ambulating. Physical examination shows nystagmus, ataxia of gait, and decreased sensation in the lower extremities. Laboratory studies show hemoglobin, 13.1 g/dL; hematocrit, 39.3%; MCV, 90 μm3; platelet count, 269,300/mm3; and WBC count 7120/mm3. A long-term dietary deficiency of which nutrient is most likely to produce these findings?
Thiamine

Bulimia
A 41-year-old woman had a chronic cough for 7 months. She had a positive tuberculin skin test result. A chest radio graph showed multiple cavitary lesions in the upper lobes of the right and left lungs. She was given isoniazid, rifampin, pyrazinamide, and ethambutol therapy. Now on physical examination 6 months later, a peripheral neuropathy is observed. Administration of which nutrient would most likely have prevented the neuropathy?
Pyridoxine (B6)

In an epidemiologic study of individuals whose BMI is greater than 35, data on lifestyle and disease patterns are collected. Investigators observe that a subset of obese individuals has a consistently high caloric intake because they lack a feeling of satiety when eating. These individuals have diminished responsiveness of a hypothalamic receptor for which molecule

This is proliferative diabetic retinopathy under the fundoscope. Describe this lesion
Neovascularization and fibrosis, can result in blindness if involves macula. Hemorrhages result from rupture of newly formed capillaries. Organization of hemorrhage can cause retinal detachment.
