We report a case of postpartum cerebral angiopathy with headache; a rare entity that affects women within the early postpartum period. Cerebral angiography revealed multiple segmental narrowings of major cerebral arteries. The patient was monitored with transcranial color-coded sonography of the middle cerebral artery. Abnormally increased flow velocity within the middle cerebral artery decreased following initiation of steroid therapy, and the patient's headache improved dramatically.

We report of a woman with post-partum cerebral angiopathy (PCA), in whom we repetitively performed transcranial Doppler sonography (TCD), MR imaging (MRI), and MR angiography (MRA) to evaluate the underlying pathophysiology. A 31-year-old woman, Gemini pregnant, complained of severe throbbing frontal headache four days after an uneventful delivery by Cesarean section. Blurred vision occurred eight days after delivery, followed by three generalized tonic-clonic seizures. Neurological examination revealed a somnolent woman without focal neurological deficits. At the day of the seizures increased flow velocities and disturbed flow were observed in the right posterior and anterior cerebral artery on transcranial Doppler (TCD). MRI showed infra- and supratentorial patchy hyperintensities in T2-weighted images and in the FLAIR sequence. Diffusion-weighted imaging revealed corresponding multi-focal hyperintense areas indicating increased diffusion and MRA showed a diffuse multisegmental narrowing of all pial arteries. MRI at day 10 was completely normal, but MRA still revealed vascular narrowing in the right posterior cerebral artery. General slight flow accelerations in all basal arteries occurred after 10 days and lasted for three weeks. PCA is apparently associated with a vascular narrowing causing cerebral ischemia with increased diffusion. Later reactive cerebral hyperperfusion is observed. Vascular narrowing and cerebral hyperperfusion still persist after MRI has normalized.

Barrier methods of contraception and natural family planning may pose unacceptable risks of unintended pregnancy for women with medical conditions in which pregnancy could be dangerous. Although more effective at preventing pregnancy, hormonal methods may affect the course of a chronic disease. The table that comprises this article outlines contraceptive choices and contraindications for women with the following diseases: breast cancer; endometrial, ovarian, and cervical cancer; deep venous thrombosis/pulmonary embolism; hypertension (past, moderate, or severe); diabetes (with and without vascular disease); liver disease; epilepsy; headache; and sickle cell disease.

FDA has approved medroxyprogesterone acetate as Depo Provera Contraceptive Injection, effective for 3 months in preventing pregnancy in women. In clinical studies, the drug's failure rate was less than 1%. However, physicians must ensure that patients receive injections on schedule to prevent pregnancy. The recommended dose is 150 mg administered every 3 months by deep, intramuscular injection in the gluteal or deltoid muscle. Most women in clinical studies of Depo Provera experienced menstrual irregularities. As use continued, amenorrhea became common, reported by 57% of the women by the end of a year of treatment. Other side effects included weight gain, headache, nervousness, abdominal pain or discomfort, dizziness, and asthenia. Physicians should administer the drug only to women found not to be pregnant, because fetal exposure may lead to low birth weight and other problems. Recent data have demonstrated that longterm use may contribute to osteoporosis, and the drug's manufacturer, the Upjohn Company of Kalamazoo, Michigan, will conduct additional research to study this possible side effect. Contraindications are similar to those for other contraceptives and include undiagnosed vaginal bleeding, known or suspected malignancy of breast, thromboembolic disorders, cerebral vascular disease, and liver dysfunction. Depo Provera was developed in the 1960s and has been approved for contraception in many other countries. When FDA first reviewed data on the drug in the 1970s, animal studies raised questions about its potential to cause breast cancer. Since then, longterm controlled clinical studies in other countries have shown a risk of breast cancer comparable to oral contraceptives, and no increased risk for ovarian, liver, or cervical cancer. The studies also showed that the contraceptive injection reduced the risk of endometrial cancer. FDA approved the drug October 29, 1992.

Proliferative angiopathy is an uncommon type of cerebral arteriovenous shunt characterized by an extensive capillary network with normal brain intermingled and few clinical symptoms (mostly seizures and headaches). This case report depicts an extensive proliferative angiopathy located in the right hemisphere. Its hemodynamic disturbances were studied with MR perfusion imaging (local or remote areas of increased time to peak, decrease ratio of signal, and relative regional cerebral blood volume values).

As migraine is associated with an increased risk for ischaemic stroke and peripheral vasospastic disorders, it was hypothesized that interictal vascular changes may be present in migraine patients. Using ultrasound and applanation tonometry, the cardiovascular properties of migraine patients were compared with those of matched control subjects. Vascular parameters of the carotid arteries, cardiac output and systemic vascular resistance did not differ between both groups. Right temporal artery diameter was larger in migraine patients (mean difference 101 micro m; 95% confidence interval (CI) 9/194 micro m; P = 0.033). At the brachial artery, migraine patients displayed a smaller distension (difference -24 micro m; 95% CI -45/-4 micro m; P = 0.021) and a decreased compliance (difference -0.025 mm2/kPa; 95% CI -0.047/-0.003 mm2/kPa; P = 0.024). Thus, migraine patients display an increased peripheral arterial stiffness. The presence of these interictal vascular changes suggests that migraine might be part of a more generalized vascular disorder.

A 29-year-old woman presented projectile vomiting followed by frontal headache, immediately upon receiving epidural analgesia for labor. The clinical picture persisted until expulsion. Although no leaking of spinal fluid into the needle or epidural catheter had been observed, post-dural puncture headache was diagnosed. The postpartum persistence of symptoms and the patient's generally worsening condition indicated the need for more thorough physical examination, which revealed signs of neurological involvement. Those findings and imaging studies (computed tomography of the brain, transcranial Doppler and magnetic resonance angiography) established a final diagnosis of postpartum cerebral angiopathy. Although epidural analgesia is increasingly requested by women entering labor, it is not a risk-free procedure. We describe a relatively unknown clinical entity, postpartum cerebral angiopathy, that developed during epidural analgesia for labor and that was initially believed to be a complication of the analgesic technique.

A 4-year-old girl was admitted to our department with the complaints of severe headache, nausea, vomiting, and photophobia. She had a 1-year history of migrainelike headache that occurred every 1 to 2 months. Her neurologic examination was normal, but T-weighted axial magnetic resonance imaging (MRI) of the brain showed flow void within the basal ganglia owing to parenchymal vascular collaterals. Magnetic resonance angiography and digital substraction carotid angiography showed both occlusion of the internal carotid artery in the supraclinoid portion and extensive parenchymal vascular collaterals. Because there was no evidence of risk factors for cerebral arterial occlusion and cerebral infarct or hemorrhage, she was diagnosed as having moyamoya disease. In any case of atypical migrainelike headache, a detailed investigation should be kept in mind to detect an underlying vascular disease such as moyamoya.

The significance of the risk factors and the rapid diagnosis of encephalic vascular disease (EVD) is the reason for this research, where the authors decided to register and analyze the non-medical people knowledge about these risk factors and the symptoms of this group of disease. For this purpose a questionnaire with questions about these facts was applied to 500 voluntaries without pre-selection, 72.6% of them with ages between 16-35 years old, and the answers analyzed by statistical methods. The authors recognized that the risk factors has a good level of knowledge by this population (87.8 % for hypertension, 76.8 % for smoking, 70.8 % for obesity, 68.7 % for sedentary persons, 66.7 % to stress, 66.3 % to alcohol ingest, 60.7 % for fat diet, 59 % to illicit drugs) while the signs and symptoms of EVD has a minor level of knowing and correction: lost sensitivity 70.3 %, headache 64.2 %, twisted mouth 59.5 %, lost or altered speech 57.5 %, dizziness 56 %, syncope 51.7 %, amaurosis 50.3 %, disequilibrium 45 %, deafness 31.2 %, weakness 41.1 %, nervousness 20.7%, chest pain 20.2 %, fatigue 15.3 % and tinnitus 18.9 %. According this data, the authors suggest that the correction or prevention of risk factors as well the precocious medical attention by the recognition of symptoms of EVD must be the object of public health programs.

The objective of the study was to assess whether a family history of vascular disorders is more common in children and adolescents with migraine than in the general population. Family history of stroke, arterial hypertension, myocardial infarction and diabetes was investigated by history taking in relatives of ambulatory children and young adults with migraine and in a control group. The odds ratios (ORs) with 95% confidence intervals (95% CI) were used as a risk measure. Using univariate and multivariate (logistic regression) analysis, family history was assessed in the whole sample and in subgroups by sex and age, degree of relationship (parents and grandparents vs. relatives), disease type (migraine with and without aura), and type of vascular disorder. The sample included 143 cases (migraine with aura 35, migraine without aura 108) and 164 controls aged 3-24 years (mean 12 +/- 3.8 years). Patients with migraine were at increased risk of vascular disorders in parents and grandparents but not in all relatives. Multivariate analysis indicated family history of stroke as most common only in boys. In conclusion, our study provides some clues to the assumption that migraine and vascular disorders have common pathogenic mechanisms and that genetic susceptibility plays a role in increasing the risk of migraine in the offspring of families with one or more cerebrovascular or cardiovascular conditions.
