Hemiplegic Migraine as the Initial Presentation of Biopsy Positive Cerebral Autosomal Dominant Arteriopathy With Subcortical Infarcts and Leukoencephalopathy.

The diagnosis of cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) in adults can be challenging. Initially, this disease can mimic embolic cerebral infarction, multiple sclerosis, and other neurological diseases on imaging studies. CADASIL is the most common hereditary cerebral angiopathy which is inherited in an autosomal dominant fashion. There is a wide variety of clinical presentations including a migraine headache, mood disturbances, cognitive dysfunction, and recurrent subcortical cerebral infarctions. This case details the hospital course and diagnosis of a 41-year-old male who initially presented with symptoms consistent with his previous diagnosis of a hemiplegic migraine who was later found to have biopsy-positive CADASIL after the symptoms failed to remit.

Heterozygous Familial Hypercholesterolemia With APOE Haplotype: A Prospective Harbinger of a Catastrophic Cardiovascular Event.

We report a very young man with heterozygous familial hypercholesterolemia (FH) with APOE haplotype and a significant cardiac family history who underwent cardiac catheterization for intermittent episodes of exertional dyspnea and was noted to have a severe triple vessel coronary artery disease (CAD). He underwent coronary artery bypass graft (CABG) surgery which was uneventful. He was discharged on antiplatelet, beta blocker, nitrate, and statin. On routine health maintenance evaluation, he had no cardiac complaints and had been tolerating well his activities of daily living.

Relative risk of progressive glaucomatous visual field loss in patients enrolled and not enrolled in a prospective longitudinal study.

OBJECTIVE: To establish the relative risk of progressive visual field loss in a sample of glaucomatous eyes enrolled in a prospective longitudinal study vs a matched sample of eyes not enrolled in a study. METHODS: The first visual field records of 66 glaucomatous eyes enrolled in a prospective longitudinal study (mean follow-up time, 3.4 years; mean number of visual field tests, 8.3) were matched to 66 eyes from patients not enrolled in a study (mean follow-up time, 3 years; mean number of visual field tests, 3.7). Eyes were matched on the basis of (1) time of enrollment, (2) length of follow-up, and (3) the extent and spatial pattern of visual field loss. Linear regression of global visual field indexes was used to measure change and the relative risk of progression was calculated for a series of progression criteria sample. RESULTS: The relative risk of progressive visual field loss was on average 368% (range, 209%-673%) higher in the eyes not enrolled in a prospective longitudinal study. CONCLUSION: Selection bias may reduce the risk of progressive visual field loss in patients enrolled in longitudinal studies.

Giant Cell Arteritis: An Atypical Presentation Diagnosed with the Use of MRI Imaging.

Giant cell arteritis (GCA) is the most common primary systemic vasculitis in western countries in individuals over the age of 50. It is typically characterised by the granulomatous involvement of large and medium sized blood vessels branching of the aorta with particular tendencies for involving the extracranial branches of the carotid artery. Generally the diagnosis is straightforward when characteristic symptoms such as headache, jaw claudication, or other ischemic complications are present. Atypical presentations of GCA without "overt" cranial ischemic manifestations have become increasingly recognised but we report for the first time a case of GCA presenting as mild upper abdominal pain and generalized weakness in the context of hyponatremia as the presenting manifestation of vasculitis that was subsequently diagnosed by MRI scanning. This case adds to the literature and emphasises the importance of MRI in the evaluation of GCA patients without "classic" cranial ischemic symptoms.

A levonorgestrel-releasing intrauterine system embedded in the omentum in a woman with abdominal pain: a case report.

INTRODUCTION: The Mirena intrauterine system has been licensed as a contraceptive in the United Kingdom since May 1995. The use of an intrauterine system as a primary method of contraception among women has been slowly increasing over the last few years and they now account for about 3% of contraceptive use in England. The Mirena intrauterine system now also has a license for the management of idiopathic menorrhagia. Women may be informed that the rate of uterine perforation associated with intrauterine contraceptive use is low (0-2.3 per 1000 insertions). The rate of perforation reported with the Mirena intrauterine system in a large observational cohort study was 0.9 per 1000 insertions. CASE PRESENTATION: In this case report, the diagnosis of an intraperitoneal Mirena intrauterine system was noted nearly four years after its insertion, despite the patient having had a vaginal hysterectomy and admissions to hospital in the interim with complaints of abdominal pain. CONCLUSION: This case report demonstrates clearly that whenever there is a question of a intrauterine system having fallen out following an ultrasound scan report showing an empty uterus, clinicians should also perform an abdominal X-ray.
