Spontaneous bilateral carotid and vertebral artery dissection presenting as a Collet-Sicard syndrome

Spontaneous dissection of the internal carotid arteries usually presents with unilateral headache, neck pain, focal ipsilateral cerebral ischaemic symptoms and a Horner's syndrome. Lower cranial nerve palsies are only rarely observed. We report a case of carotid and vertebral dissections presenting as a unilateral palsy of the ninth to twelfth cranial nerves (Collet-Sicard syndrome).     

Case report: sicca syndrome due to primary amyloidosis

Sicca syndrome consists of two major clinical findings: keratoconjunctivitis sicca and xerostomia due to destruction of the lacrimal and salivary gland parenchyma. Although it is most often due to Sj?gren's syndrome, a variety of other diseases causes sicca syndrome. We report the rare case of a patient with gland infiltration in primary amyloidosis. Sonographic, computed tomographic and magnetic resonance findings are presented.     

Evaluation of carotid endarterectomy with sequential MR perfusion imaging: a preliminary report

BACKGROUND AND PURPOSE: Current indications for carotid endarterectomy are determined by balancing the relative risks of surgery with the benefits of reduced risk of subsequent stroke. Our purpose was to use MR perfusion imaging to assess patients being considered for carotid endarterectomy and to monitor sequential changes in MR perfusion characteristics after surgery. In particular, we wished to determine whether this technique could be used to detect changes that might be related to post-carotid endarterectomy hyperemia. METHODS: We used a single-section gradient-recalled echo sequence to investigate 14 patients being examined before possible surgery for carotid artery disease. In the 12 patients in whom carotid endarterectomy was performed, sequential studies were performed 3 to 5 days after surgery and at 3 months. Analysis of bolus-arrival-time (BAT) images was performed. RESULTS: Significant delays in preoperative BAT images of 0.89 seconds (range, 0.05 to 3.22 seconds) were apparent between hemispheres. Excluding the two patients with contralateral internal carotid artery (ICA) occlusion, early arrival, possibly indicating postoperative hyperemia, was seen in five patients immediately after carotid endarterectomy but resolved within 3 to 5 months after surgery. CONCLUSION: MR perfusion imaging shows differences in BAT between hemispheres in patients with ICA stenosis. Changes in perfusion characteristics after carotid endarterectomy are complex, and early BAT on the operative side can occur soon after endarterectomy in over half those patients without an occluded contralateral vessel. The significance of these findings with regard to patient outcome and risk of postoperative hyperemia requires further investigation.     

HELLP syndrome. Case report

Genitourinary sarcomas are very rare entities. This paper contributes one case report of an undifferentiated pelvic fibrosarcoma in a 53-year old patient. It also includes some observations on the clinical development, complementary studies used, difficulties for the pathoanatomical diagnosis and treatment issues.     

Kenny-Caffey syndrome. Case report

We investigated whether survival was related to recent childbirth or parity in a cohort of 540 women diagnosed with breast cancer before the age of 45 years who were followed for up to 14 years. Women who had given birth within 2 years before their diagnosis of breast cancer were at increased risk of dying, compared with nulliparous women, with an adjusted relative risk of 3.1 (95% confidence interval = 1.8-5.4). There was a moderate association of parity with mortality, with an adjusted relative risk of 1.8 (95% confidence interval = 1.2-2.9) for women with three or more births, compared with nulliparous women.     

Aortic dissection and Turner''s syndrome: case report and review of the literature

Combination chemotherapy with 5-FU and CDDP was given to two patients with obstructive jaundice due to intra-abdominal lymph-node metastases of advanced and recurrent gastric cancer. One patient was a primary case associated with lymph-node metastases of portal fissure and periaorta, and the other was a recurrent case associated with lymph-node metastases of hepatoduodenal ligament and periaorta. The regimen consisted of 5-FU 1,000 mg/ m2 (day 1-5, continuous infusion) and CDDP 100 mg/m2 (day 3, 1 hr drip infusion). The interval was from the 6th to 21st day. The response to chemotherapy showed shrinking of intra-abdominal lymph-nodes and reopening of the biliary tract. The patients could be discharged from the hospital without PTBD tube and enjoyed a better quality of life (QOL). This therapy is thought to be effective against obstructive jaundice due to intra-abdominal lymph-node metastases of advanced and recurrent gastric cancer.     

Clinical and genetic analysis of primary bilateral adrenal diseases (micro- and macronodular disease) leading to Cushing syndrome

Primary bilateral adrenocortical diseases are rare entities that have recently been appreciated as potential causes of Cushing syndrome. They include (i) primary pigmented adrenocortical disease (PPNAD), also known as "micronodular adrenal disease", which is a genetic disorder that is often associated with Carney complex, and (ii) massive macronodular adrenocortical disease (MMAD), a rare disorder of unknown etiology that affects older adults. Carney complex is a multiple endocrine neoplasia (MEN) syndrome that affects not only the adrenal cortex, but also the pituitary, thyroid, and gonads. It is associated with pigmentation abnormalities as well as myxomas and other mesenchymal and neural crest neoplasms. The inheritance of the complex is autosomal dominant, and genetic mapping has shown that at least two loci are involved in its pathogenesis. MMAD appears to be an isolated finding in most cases, and a genetic defect has not yet been defined. Ectopic expression of hormone receptors has been implicated in several cases of MMAD, but an underlying deficit has not been detected. Bilateral adrenocortical hyperplasia has also been described in McCune-Albright syndrome and MEN type-1, but this finding is not always associated with hypercortisolism. The genetic defects for these diseases are known, but their role in adrenal cortex pathophysiology has not been fully elucidated. Identification of the molecular defects responsible for bilateral adrenocortical disorders is expected to shed light on many aspects of early adrenal gland differentiation and tumorigenesis.     

Hyperperfusion syndrome following carotid endarterectomy: evaluation using diffusion-weighted magnetic resonance imaging--case report

OBJECTIVE: Epidemiological evidence suggests that resistance to insulin is the common nexus of the accumulation of factors in patients at high cardiovascular risk. To find a test which enables resistance to insulin to be identified in large populations will allow preventive and therapeutic measures to be taken. DESIGN: Crossover. SETTING: Carrascosa del Campo and Cuenca Health Centres. PARTICIPANTS: 408 patients (154 men and 254 women), all the non-diabetic obese patients at the two health centres, were studied. MEASUREMENTS AND MAIN RESULTS: Levels of cholesterol, triglycerides and uric acid were measured. Patients were medically examined, and blood pressure, waist and hip measurements, toxic habits and cardiovascular history were found. They were classified by pathology and normograms. The O'Sullivan and microalbuminuria tests were performed, and all the statistical associations with biochemical and medical characteristics were studied. The O'Sullivan test was significantly associated (p < 0.01) with cardiovascular risk and insulin-resistance factors such as hypercholesterolaemia (RR 1.63), hypertension (RR 1.92), hypertriglyceridaemia (RR 2.47), hyperuricaemia (RR 1.80), with the Berglund resistance index (RR 1.52) and the microalbuminuria test (RR 1.83). The association was more consistent when there were a number of factors combining. There was no relationship with the waist/hip index found. CONCLUSION: The O'Sullivan test, on its own or with the microalbuminuria test, seems very useful for identifying obese subjects with resistance to insulin.     

Diminished ability to interpret and report internal states after bilateral medial temporal resection: Case H.M.

Conducted 2 experiments on a 54-yr-old man who became amnesic when he was 27 yrs old following a bilateral resection in the medial temporal lobe region for epilepsy. To document the clinical reports that he rarely commented on such internal states as pain, hunger, and thirst, his thermal pain perception was examined in relation to his other somatosensory capacities, and his reports of hunger and thirst were assessed before and after meals. To investigate the effect of limited memory ability on the reporting of internal states, S's performance was compared with that of 5 other Ss (aged 22–48 yrs) with global amnesia. 19 22–74 yr old normal controls were also assessed. Results show that S's information about his internal states was less available or less accessible than normal and that his impairment was not attributable to his memory deficit. Instead, it is believed that the bilateral resection of the amygdala accounted for S's poor understanding of his internal states.

A physiologic approach to the problems of simutaneous bilateral neck dissection

A number of physiologic derangements have been observed resulting from the management of head and neck cancer with resection and simultaneous bilateral neck dissection. A protocol evolved to minimize morbidity from these complications was used on seventeen patients. Eleven are alive and free of disease and there was no mortality.     

Case report: Gianotti-Crosti syndrome associated with human herpesvirus-6 infection

A cohort of 34,560 men and 6128 women employed in 660 European factories manufacturing reinforced plastic products, followed up originally to assess the risk of cancer, was used to assess the risk of non-malignant respiratory diseases associated with exposure to styrene. Mortality from pneumonia was associated with intensity of exposure to styrene, but this may have been due to chance. Mortality from bronchitis, emphysema, and asthma was not associated with styrene exposure.     

Inhaled nitric oxide during anesthesia for bilateral single lung transplantation. Case report

Recently inhaled nitric oxide (iNO) has been used as pulmonary vasodilator without any effect on systemic hemodynamics. iNO has been also used in cardiac and thoracic surgery, involving lung transplantation. In this case report a patient, 41 years old female, affected by bronchiectasis, underwent bilateral sequential single lung transplantation and during one lung ventilation and pulmonary artery clamped iNO allowed to avoid cardiopulmonary bypass and to carry out the procedure successfully.     

Reversible bilateral opercular syndrome secondary to AIDS-associated cerebral toxoplasmosis

A case of reversible anterior bilateral opercular syndrome (Foix-Chavany-Marie syndrome) secondary to cerebral toxoplasma abscesses is described in a patient with AIDS. The symptoms regressed following antitoxoplasma and antiedema drug therapy. Although this is the first reported AIDS-related case, the syndrome is likely to recur in AIDS sufferers in whom multifocal cerebral lesions are common.     

CHILD syndrome. Case report of a rare genetic dermatosis

We report on a 2-month-old girl who developed unilateral ichthyosiform erythrodermia on the right side of her trunk and the right leg 1 week after birth. In addition, there was hexadactyly of her right hand. Apart from that, close physical examinations did not reveal any other defects. We diagnosed this condition as CHILD syndrome (congenital hemidysplasia with ichthyosiform nevus and limb defects).     

Giant intracranial aneurysm associated with Marfan's syndrome. Case report

The authors describe a giant intracranial internal carotid aneurysm in a patient with Marfan's syndrome. Treatment consisted of internal carotid ligation with subsequent thrombosis of the lesion. The patient's course was complicated by carotid arterial dissection and possible laminar thrombosis within the aneurysm increasing the size of the lesion. Three clinical syndromes, Marfan's, Ehlers-Danlos, and pseudoxanthoma esasticum, are discussed. The literature is reviewed with reference to the hazards of treatment of vascular pathology in patients with these connective tissue disorders.
