1/393. Increased sister chromatid exchange in bone marrow and blood cells from Bloom's syndrome.

    Bone-marrow cells from a patient with Bloom's syndrome cultured for 48 h in the presence of BudR exhibited a striking increase in the number of sister chromatid exchanges (SCEs) in comparison to that in the marrow cells of a patient with treated polycythemia vera (PV). Thus, it appears that an increased incidence of SCE in Bloom's syndrome occurs in various differentiated types of cells, not just blood lymphocytes, and constitutes the syndrome's most characteristic cytogenetic feature. In contrast, the incidence of SCE was not increased in marrow cells and lymphocytes of the particular PV patient studied here, whose cells did exhibit increased numbers of chromatid and chromosome gaps and breaks, presumably as result of the patient's earlier treatment. An increased frequency of SCE was demonstrated in Bloom's syndrome lymphocytes using both a technique based on BudR incorporation and one based on labeling with tritated deoxycytidine. This observation constitutes evidence against the increase of SCE being due to an unusual reaction to BudR. By conventional cytogenetic techniques, chromosome instability, including chromatid and chromosome breaks, but no homologous chromatid interchanges were also recognized in Bloom's syndrome bone-marrow cells incubated in vitro (without BudR) for either 1.k or 16 h. This observation points to the existence of chromosome instability in vivo. ( info)

2/393. Jejunal telangiectasias as a cause of massive bleeding in a patient with scleroderma.

    Telengiectasias (arteriovenous malformations) can be seen in scleroderma throughout the gastrointestinal tract, including the stomach, small bowel and colon. Massive gastrointestinal bleeding rarely results from these malformations in scleroderma. The case of a patient presenting with severe jejunal bleeding secondary to telangiectasias with special regard to the management is discussed. This case emphasizes the importance of endoscopic examination combined with mesenteric angiography in patients with scleroderma who present with a high index of suspicion of telangiectasias as a source of bleeding.

3/393. Erythrosis pigmentosa mediofacialis (Brocq) and erythromelanosis follicularis faciei et colli in the same patient.

    Erythrosis pigmentosa peribuccalis (Brocq) (or erythrosis pigmentosa mediofacialis) and erythromelanosis follicularis faciei et colli, have been regarded as different disorders, mainly because the first occurs on the mediofacial area and is common in women and the second mostly occurs pre-auricularly in men. Both conditions show histological signs of abnormal follicular keratinization with teleangiectasia and round cell infiltrate. An increase in the level of melanin has been seen in some patients. We describe here a woman in whom lesions started in the middle of the face and later became evident in the pre-auricular area. This suggests that the two conditions are in fact the same disease. As a neutral term for this not uncommon disorder we propose erythrosis pigmentosa faciei et colli. ( info)

4/393. Infantile hiv encephalopathy associated with cerebral and cerebellar telangiectases.

    We describe a paediatric case of hiv encephalopathy associated with cerebral and cerebellar telangiectases. Although immunohistochemistry failed to show hiv in the walls of dilated blood vessels, or in their vicinity, brain capillary telangiectases might be an additional complication indirectly related to paediatric hiv infection.

5/393. Cutaneous telangiectasias, sparse hair, and type I membranoproliferative glomerulonephritis.

    We report the unusual association of normocomplementemic type I membranoproliferative glomerulonephritis in a 10-year-old girl with sparse red hair, absent eyebrows and eyelashes, cutaneous telangiectasias, and an atrial septal defect. ( info)

6/393. Surgery of angiomas in the brainstem with a stress on the presence of telangiectasia.

    This report deals with the surgery of angiomas other than arteriovenous malformation in the brainstem. The surgical cases were three cavernomas, two telangiectasias, and two venous malformations. We performed surgery when an angioma bled and the resulting hematoma was situated near the surface of the brainstem or the fourth ventricle. The cases were operated on at the subacute or chronic stages after hemorrhage. Although a magnetic resonance (MR) image showed a subacute or chronic localized hematoma with a low intensity rim, the case was not always a cavernoma, but a telangiectasia. Cavernomas could be totally removed, but telangiectasia could not. In the cases of medullary venous malformation the diagnosis was obtained radiologically, and when the hematoma was large, only hematoma evacuation was performed. In all cases the postoperative Karnofsky scores were improved or unchanged. Postoperative rebleeding in the hematoma cavity continued insidiously in a case of telangiectasia. The abnormal vessels of telangiectasia in the brainstem were preoperatively not visualized by cerebral angiography or MR imaging, but became visualized by enhanced MR imaging after evacuation of hematoma in two cases. It is stressed that an angioma with a hematoma intensity core surrounded by a low intensity rim on MR images is not always a cavernoma, but possibly is a telangiectasia. ( info)

7/393. Polymorphic light eruption occurring solely on an area of naevoid telangiectasia.

    We report the case of a 60-year-old woman presenting with polymorphic light eruption occurring solely on an area of acquired naevoid telangiectasia. We have hypothesized that increased blood flow in the telangiectatic skin may reduce the threshold for expression of photosensitivity by permitting enhanced inflammatory cell trafficking to the overlying tissue.

8/393. saphenous vein graft ectasia: an unusual late complication of coronary artery bypass surgery. A case report.

    Aneurysms and ectasias of saphenous vein grafts are infrequent complications of coronary artery bypass surgery. They usually present as an expanding asymptomatic mediastinal mass on chest x-ray film or computed tomography scan. Though rare, they must be excluded from the differential diagnosis of mediastinal masses to avoid potentially dangerous needle biopsy. The authors describe ectasia of a saphenous vein graft in a 62-year-old man 14 years after coronary artery bypass surgery. The relevant literature is also discussed. ( info)

9/393. Atrophie blanche-like scarring after pulsed dye laser treatment.

    Pulsed dye laser treatment is well established for the treatment of port-wine stains and other vascular skin lesions. Although hyperpigmentation is quite common, other side effects such as hypopigmentation and atrophic scarring occur infrequently, and hypertrophic scarring is rare. ( info)

10/393. Unusual vascular dysplasia presenting as an intra-abdominal catastrophe.

    A case of severe, generalised vascular dysplasia presenting as an intra-abdominal catastrophe is reported. Associated clinical features included cutis marmorata telangiectatica congenita, congenital glaucoma, hypertension, and focal fits. The case has been reported in view of its rarity and nature of presentation. ( info)
