BACKGROUND: Reversible cerebral vasoconstriction syndrome (RCVS) and posterior reversible encephalopathy syndrome (PRES) are both rare disorders. The pathophysiology of both diseases is not yet fully understood. METHODS: We report the unique case of a 19-year-old comatose woman who was brought to the ER after a series of generalized tonic-clonic seizures 6 days post peridural anesthesia for cesarean section. Vital signs and initial laboratory testing including urine analysis and drug screening were unremarkable...

OBJECTIVE: The objective of our study was to determine whether the presence of individual imaging signs of spontaneous intracranial hypotension (SIH) is correlated with increasing duration of headache symptoms. Of particular interest is the relationship of symptom duration to dural enhancement because it is the most commonly identified imaging sign in patients with SIH. MATERIALS AND METHODS: Eighty-nine patients with SIH who underwent pretreatment brain MRI and total-spine CT myelography and whose medical record included data on the duration of clinical symptoms were included in this cross-sectional retrospective study...

OBJECTIVE: [(18)F]Fluciclovine (anti-[(18)F]FACBC) has demonstrated diagnostic efficacy for cancers of the brain where [(18)F]fludeoxyglucose has limitations. We conducted a phase IIa study of anti-[(18)F]FACBC to assess its accumulation pattern and safety in patients with malignant glioma. METHODS: Five patients with glioma scheduled for brain tumor resection received anti-[(18)F]FACBC. Brain positron emission tomography (PET) was performed following intravenous administration of anti-[(18)F]FACBC, and subsequently, preoperative gadolinium contrast-enhanced T1-weighted (CE-T1W) magnetic resonance imaging (MRI) was performed for surgery...

BACKGROUND: Many physicians believe that advanced practice clinicians (APCs [nurse practitioners and physician assistants]) provide care of relatively lower value. OBJECTIVE: To compare use of low-value services among U.S. APCs and physicians. DESIGN: Service use after primary care visits was evaluated for 3 conditions after adjustment for patient and provider characteristics and year. Patients with guideline-based red flags were excluded and analyses stratified by office- versus hospital-based visits, acute versus nonacute presentations, and whether clinicians self-identified as the patient's primary care provider (PCP)...

A 21-year-old man presented to his local emergency department with 5 days of headache, which was dull, occipital, bilateral, nonthrobbing, and progressively worsening. It was associated with mild fever, photophobia, and neck pain and stiffness. He had no history of headache, chronic illness, recent vaccinations, cutaneous rash, cough, diarrhea, arthralgia, or myalgia. He was from Ecuador and had been living in the United States for less than 1 year. He had been incarcerated while in Ecuador. Sublingual temperature on admission was 102...

A 29-year-old man, with no significant past medical history, was in his usual state of health until the afternoon of admission. The patient was seated at work eating lunch when he suddenly noticed that his vision became blurry. He covered his right eye and had no visual difficulty but noted blurry vision upon covering his left eye. At this point, the patient tried to stand up, but had difficulty walking and noticed he was "falling toward his left." Facial asymmetry when smiling was also appreciated. The patient denied any alteration in mental status, confusion, antecedent or current headaches, aura, chest pains, or shortness of breath...

We report on the case of a 20 year old woman with no previous psychiatric history, who displayed a first episode of catatonia with acute onset. Symptoms started plainly with sudden general impairment, intense asthenia, headache, abdominal pain and confusion. After 48 hours, the patient was first admitted to an emergency unit and transferred to an internal medicine ward afterwards. She kept confused. Her behaviour was bizarre with permanent swinging of pelvis, mannerism, answers off the point and increasingly poor...

Isolated sphenoid sinus disease (ISSD) is a relatively uncommon disease. The present study is a retrospective review of 122 patients with ISSD who were treated at the Department of Otolaryngology, Eye, Ear, Nose and Throat Hospital at Shanghai Medical University over a 25-year period. The diagnosis of ISSD was made on the basis of history and physical examination, signs and symptoms, nasal endoscopy, and computed tomography (CT) and magnetic resonance imaging (MRI). The final diagnosis of ISSD was confirmed by histopathologic and microbiological examinations of the surgical specimens...
