patient has fever, hypotension, swelling, and erythema of his left leg. Notably, his leg is more painful to palpation than might be expected after visual inspection. These symptoms are very concerning for necrotizing fasciitis. Necrotizing fasciitis is a fulminant infection of the subcutaneous tissue that spreads rapidly along the fascial planes and leads to extensive tissue necrosis and shock. Treatment • Requires surgical debridement & broad-spectrum antibiotics

The headache, lethargy, and neck stiffness suggest subarachnoid hemorrhage secondary to rupture of a mycotic aneurysm. Mycotic or infected arterial aneurysms can develop due to metastatic infection from IE, with septic embolization and localized vessel wall destruction in the cerebral (or systemic) circulation. Intracerebral mycotic aneurysms can present as an expanding mass with focal neurologic findings or may not be apparent until aneurysm rupture with stroke or subarachnoid hemorrhage. The diagnosis of mycotic cerebral aneurysm can usually be confirmed with computed tomography angiography. Management includes broad-spectrum antibiotics (tailored to blood culture results) and surgical intervention (open or endovascular).

AIDS Dementia:
AIDS Dementia: samer kareem 6,435 Views • 2 years ago

ADC was first identified early in the AIDS epidemic as a common and novel CNS syndrome.(4,5) The three components of the term, AIDS dementia complex embody central features of the condition. AIDS emphasizes its morbidity and poor prognosis, particularly when its severity is at stage 2 or greater (see Table 1), a severity comparable to other clinical AIDS-defining complications of HIV-1 infection. Dementia designates the acquired and persistent cognitive decline with preserved alertness that usually dominates the clinical presentation and determines its principal disability. Complex emphasizes that this disease not only impairs the intellect, but also concomitantly alters motor performance and, at times, behavior. This involvement of the nervous system beyond cognition is evidence of a wider involvement of the CNS than occurs in some other types of dementia such as Alzheimer's disease. Additionally, myelopathy may be an important, indeed predominating, aspect of ADC, and organic psychosis may also be a feature in a subset of patients (see Rheumatologic and Musculoskeletal Manifestations of HIV). These manifestations are therefore also encompassed within this term. By contrast, neither neuropathy nor functional psychiatric disturbance are included in ADC.

Cranial Nerves Anatomy
Cranial Nerves Anatomy samer kareem 40,689 Views • 2 years ago

There are twelve cranial nerves in total. The olfactory nerve (CN I) and optic nerve (CN II) originate from the cerebrum. Cranial nerves III – XII arise from the brain stem (Figure 1). They can arise from a specific part of the brain stem (midbrain, pons or medulla), or from a junction between two parts: Midbrain – the trochlear nerve (IV) comes from the posterior side of the midbrain. It has the longest intracranial length of all the cranial nerves. Midbrain-pontine junction – oculomotor (III). Pons – trigeminal (V). Pontine-medulla junction – abducens, facial, vestibulocochlear (VI-VIII). Medulla Oblongata – posterior to the olive: glossopharyngeal, vagus, accessory (IX-XI). Anterior to the olive: hypoglossal (XII). The cranial nerves are numbered by their loca

Uncomplicated acute otitis media (AOM) should be treated empirically with amoxicillin. Recurrent AOM should raise concern for beta-lactamase resistance and warrants treatment with amoxicillin-clavulanic acid. Ototopical medications are unnecessary, even if there is tympanic membrane perforation.

Slipped Capital Femoral Epiphysis (SCFE)
Slipped Capital Femoral Epiphysis (SCFE) samer kareem 5,226 Views • 2 years ago

There is a strong association with obesity. In children younger than 10 years, it is associated with metabolic endocrine disorders {hypothyroidism, panhypopituitarism, hypogonadism, renal osteodystrophy, growth hormone abnormalities). SCFE is considered chronic if it has been present more than 3 weeks and acute if it has been present for 3 weeks or less. It is called "stable" if the patient can bear weight and "unstable" if the patient cannot ambulate. Unstable SCFE is associated with more complications, including avascular necrosis of the femoral head (AVN). SCFE is diagnosed by x-ray of the pelvis and bilateral hips. The underlying cause is a widened epiphyseal growth plate, due to abnormal cartilage maturation and endochondral ossification. The treatment is surgical, requiring immediate internal fixation with a single screw. Delay in treatment {> 24 hours) leads to increased AVN, SCFE progression from stable to unstable, and high risk of future degenerative arthritis. Prophylactic contralateral fixation of the unaffected hip is not routinely done in the U.S., except in patients with endocrine abnormalities.

Cerclage is indicated in a patient with a history of painless cervical dilation and a second trimester loss. It is also indicated in a patient with a history of preterm birth and a short cervix found on ultrasound between 16-24 weeks gestation. Cerclage placement occurs after the first trimester in case the pregnancy is genetically abnormal and would likely result in a first trimester loss.
