Typical cases of pollen allergen (hayfever, allergic asthma), together with isolated non-respiratory "equivalent" manifestations (urticaria, eye conditions, headache, etc.), are easy to detect on the basis of skin tests and the clinical history. Such manifestations may also occur in "false pollen
On February 7, 2012, the Maine Center for Disease Control and Prevention was notified of suspected measles infection in an unvaccinated woman aged 57 years. The patient went to her medical provider on January 30 after 3 days of headache and fever and 2 days of papular rash. The rash began on her
A 28-year-old man had recurrent episodes of headache, ophthalmoplegia, and ptosis. MR imaging showed a mass within the sphenoid sinus. TI-201 imaging showed intense uptake in the region of the sphenoid sinus and right middle fossa with moderate retention of activity, suggesting the diagnosis of a
Prior studies examining the sensitivity of cranial computed tomography (CT) for the detection of subarachnoid hemorrhage (SAH) have used the final radiology report as the reference standard. However, optimal sensitivity may have been underestimated due to misinterpretation of reportedly normal
BACKGROUND
Rapid diagnostic tests play a pivotal role in the early diagnosis of malaria where microscopy or polymerase chain reaction are not immediately available.
METHODS
We report the case of a 39 year old traveler to Canada who presented with fever, headache, and abdominal pain after visiting
OBJECTIVE
Spontaneous spinal CSF leaks are an important cause of new-onset headaches. Such leaks are reported to be particularly common at the cervico-thoracic junction. The authors undertook a study to determine the significance of these cervico-thoracic CSF leaks.
METHODS
The patient population
A 34-year-old right-handed female presented to the emergency department with a worsening headache, neck stiffness, intermittent abnormal sensation, and right arm weakness. Shortly after arrival, she had a generalized tonic-clonic seizure. A noncontrast head computed tomography scan revealed a
OBJECTIVE
Spontaneous intracranial hypotension due to a spinal cerebrospinal fluid (CSF) leak is an important cause of new daily persistent headaches. Spinal neuroimaging is important in the treatment of these patients, particularly when direct repair of the CSF leak is contemplated. Retrospinal
Four patients who had acquired immunodeficiency syndrome and who were evaluated for headache within a 3-week period had false-positive results of serum cryptococcal antigen tests. This cluster of false-positive test results appeared to be due to inactivation of the pronase vial in the test kit, a
A previously healthy 26-year-old man presented with fever, headache, skin rash, and thrombocytopenia. Cultures of blood and cerebrospinal fluid yielded a fastidious gram-negative bacillus, identified as DF-2. A unique feature of this case was the presence of a false-positive latex agglutination
BACKGROUND
Spinal arteriovenous malformation (SAVM) is a relatively rare disease characterized by a high incidence of intramedullary and subarachnoid haemorrhage. When the hemorrhage is profuse and the SAVM is in the cervical region the symptoms (disturbance of consciousness, papilledema, cranial
