2022-10-12 08:43:02 A 5-year-old boy has developed persistent food-seeking behavior over the past few months. His mother initially thought that the boy was undergoing a growth spurt, but despite how much she fed him he never seemed satisfied. He has now gained more than 4.5 kg (10 lb). The boy has also started complaining of a headache and nausea in the morning. His physical examination is significant for BMI of 32 kg/nv. Temperature is 37 .2 C (99 F), blood pressure is 100/70 mm Hg, pulse is 92/min, and respirations are 16/min . His pediatrician becomes concerned about possible central nervous system involvement.

2022-10-11 22:43:02 Educational objective: Menlngiomas are common adult intracranial tumors that typically arise in regions of dural reflection (eg, falx cerebri, tentorium cerebelli). Lesions involving the primary somatosensory cortex typically result in contralateral sensory loss, whereas damage to the parietal association cortex (particularly in the nondominant hemisphere) may cause contralateral hemineglect due to impaired visuospatial processing.

2022-10-10 22:42:01 Educational objective: LS radiculopathy occurs due to compression of the LS nerve root usually as a result of vertebral disc herniation or spinal foraminal stenosis. Patients typically present with back pain radiating down the leg with sensory loss over the buttocks, lateral thigh and calf, and dorsal foot. There may also be weakness on foot dorsiflexion, inversion, eversion, and toe extension. Open / Comment

2022-10-10 08:41:01 A 64-year-old obese man comes to the office due to progressive low back pain for the past 6 months that is beginning to interfere with his job. The patient works as a greeter for a local supermarket and was recently given a written warning for taking too many breaks during his shift. He describes his discomfort as a sharp, shooting pain that radiates to the right leg. The pain worsens with prolonged standing or walking and improves with tying down. The patient has a history of hypertension and gastroesophageal reflux disease. On physical examination, his pain is reproducible with right-sided straight leg raise testing. Imaging studies show a large osteophyte compressing the nerve traversing the right L5-S1 neural foramen. Open / Comment

2022-10-09 21:40:05 Educational objective: The median nerve courses between the humeral and ulnar heads of the pronator tares muscle and then runs between the flexor digitorum superficialis and the flexor digitorum profundus muscles before crossing the wrist within the carpal tunnel. Proximal nerve lesions may result in sensory loss over the first 3 digits and impairment of thumb flexionlopposition, flexion of the second/third digits, and wrist flexionlabduction. Open / Comment
