Q: Abstract: The presence of patella alta has been linked to recurrent dislocation of the patella and the patello-femoral stress syndrome. It is not known whether patella alta is an inherited or acquired trait. To investigate the relationship of patella during the adolescent growth spurt, serial orthoroentgenograms (growth study films) were retrospectively analyzed in 19 patients. Two were found in whom proximal patella migration could be correlated (r = 0.85) with femoral growth rate. This was significant at the p = 0.01 level. Girls had a higher correlation of patella height to growth rate than boys. In certain cases, patella alta is an acquired rather than inherited condition; this supports the theory that overgrowth during the growth spurt can lead to patella alta in some individuals.

Q: Abstract: Cerebral cysticercosis is a parasitic infestation with a highly variable prognosis and diverse clinical manifestations. Over the period of two years 51 patients were studied prospectively with this infestation, paying particular attention to the duration and severity of the illness, clinical course, CT findings and therapeutic modalities. Patients with parenchymal cysts or calcification without hydrocephalus had a benign disorder presenting commonly with seizures. This type of infestation usually is long-standing, almost never requires surgical treatment, responds to praziquantel therapy and has a good prognosis. In contrast, patients who present with hydrocephalus, large supratentorial cysts, multiple granulomata with cerebral oedema or with vasculitis and cerebral infarction, have an aggressive, acute or subacute illness, presenting with raised intracranial pressure, gait disturbances, mental changes, seizures, cranial nerve palsies, hemisphere syndromes, chronic meningitis and stroke. This malignant form usually requires surgical therapy, does not respond to praziquantel and may produce a fatal outcome or serious sequelae.

Q: Abstract: The kinetics of caffeine elimination were followed in a ten month old female acutely intoxicated on a street form of the drug. Urine drug screening by gas chromatography-mass spectrometry also showed the presence of ephedrine, phenylpropanolamine, caffeine, theophylline and theobromine. Blood analyses using high pressure liquid chromatography gave evidence for the presence of theobromine, theophylline, caffeine and 1,7-dimethylxanthine. Sequentially taken blood samples determined that the initial stage of caffeine elimination was nonlinear. The Vmax = 27.6 micrograms/ml/hr and Km = 284.6 micrograms/ml. At a plasma level of approximately 30 micrograms/ml the elimination became first order with ke = 0.097 hr-1 and t 1/2 = 7.1 hr. The metabolic generation of theophylline and its elimination were also studied. Theophylline ke = 0.069 hr-1 and t 1/2 = 10.0 hr. Elimination of both drugs was anomalously long for a child of this age.
