Tremor as the first neurological manifestation of Sneddon's syndrome.

We report on a 54-year-old woman with Sneddon's syndrome manifested by livedo reticularis, fetal losses, hypertension, and high antinuclear antibody titres. At the age of 42 years she developed tremor of the trunk, limbs, and head only in the standing position that interfered with walking, followed some years later by cognitive decline and a parkinsonian syndrome. T2-weighted brain magnetic resonance imaging showed high signal in cortical areas, basal ganglia, midbrain, and cerebellum.

Cutaneous manifestations of familial amyloidotic polyneuropathy.

Familial amyloidotic polyneuropathy is an autosomal dominant amyloidosis, characterized by the systemic deposition of amyloid with a particular involvement of the peripheral nerves. The disease generally manifests as a severe sensory, motor and autonomic neuropathy. Cardiomyopathy, nephropathy, vitreous opacities and carpal tunnel syndrome may occur in a variable association with the neuropathy. Trophic dermatological lesions are frequent in the more advanced stages of the disease. We examined the skin of 142 patients. The cutaneous manifestations more frequently observed were: xerosis (81.6%), seborrheic dermatitis (21.8%), traumatic and burn lesions (19.7%), acne (18.3%), neurotrophic ulcers (14%) and onychomycosis (10.5%). Among the hepatic transplanted patients (31%), seborrheic dermatitis and acne were the most frequent diagnoses.

Plasma cell cheilitis.

Plasma cell cheilitis is a rare inflammatory disorder of the lip with a characteristic band-like infiltrate of plasma cells in the upper dermis. Differential diagnosis should consider allergic/irritant contact cheilitis, candidiasis, syphilis, Queyrat's erythroplasia, granulomatous cheilitis, plasmoacanthoma, plasmacytoma, squamous cell carcinoma and exfoliative or factitious cheilitis. We observed plasma cell cheilitis in a 60-year-old Caucasian female who had a partial response to topical steroids and oral griseofulvin.

[Hospital outcome and short-term follow-up of elderly patients presenting to the emergency unit with congestive heart failure].

PURPOSE: To evaluate the in-hospital (IH) outcome and the short-term follow-up of predominantly elderly patients presenting to an emergency room (ER) with congestive heart failure (CHF). METHODS: In an 11 month period, 57 patients presenting to the ER with CHF were included. Mean age was 69 +/- 15 years (27 to 94) and 39 (68.4%) were male. CHF diagnosis was based on the Boston criteria. We evaluated IH outcome and prognosis in a mean follow-up of 5.7 +/- 2.7 months (1 to 12). In addition, some mortality predictors and mechanisms of death according on the ACME system were identified. RESULTS: Eight patients (14%) died in the IH period. Modes of death were circulatory failure (CF) in 7, and peri-operative (PO) in one (aortic valve replacement). During follow-up 9 deaths occurred. Five were due to CF, 2 were sudden and 2 were PO (mitral valve replacement and ventriculectomy). Six-months and 1-year survival rates of the patients who were discharged were 82% and 66%, respectively. Sodium lower than 135 mEq/l (p = 0.004) and female gender (p = 0.038) were independent predictors of mortality. CONCLUSION: Elderly patients with CHF admitted to the ER have high in-hospital and short-term follow up mortalities. The majority die from CF due to worsening heart failure.

[Myocardial revascularization in left coronary trunk lesion in patients over 65 years old].

PURPOSE: To study the short and long-term follow-up of patients with left main coronary artery disease (LMCAD) and age over 65 years, by comparing the results with patients under 65 years-old. METHODS: Twenty-two patients with LMCAD and mean age of 69 +/- 3.5 years (group I) were underwent isolated coronary artery bypass grafting (CABG) and compared to 31 patients with LMCAD, mean age of 54 +/- 7 years (group II), who also underwent isolated CABG. The life-table Kaplan-Meyer method was used to estimate the post-operative survival. The chi-square and Student "t" test were used when necessary. RESULTS: Despite higher operative mortality in group I (9.1% x 3.2%), the difference was statistically not significant. The operative morbidity was similar in both groups. Actuarial survival at 4 years was 85% in group I and 95% in group II. Actuarial survival free of cardiac events was 69% in group II and 75% in group II. CONCLUSION: The CABG is well tolerated and had low morbidity and acceptable mortality in old patients with LMCAD. The long-term survival in these patients was very similar to the younger patients.

Immunohistochemical characterisation of probable intravascular haematopoiesis in the vasa rectae of the renal medulla in acute tubular necrosis.

Immunohistochemistry was applied to identify the nature of the nucleated cells that accumulate in the vasa rectae of the corticomedullary junction in acute tubular necrosis. In all 6 cases studied, there were intravascular cells that reacted with monoclonal antibodies to erythroblast, macrophages, myeloid cells, T and B lymphocytes and rare megakaryocytes. The findings are consistent with the occurrence of intravascular haematopoiesis in the renal medulla in acute tubular necrosis.

Case report: cyclosporin A-induced neurotoxicity.

Acute encephalopathy is a recognized toxic effect of Cyclosporin A (CsA) in organ transplantation recipients. A 16-year-old girl presented with acute encephalopathy 2 weeks after CsA and methylprednisolone medication for idiopathic uveitis. Magnetic resonance imaging showed cortical and white matter occipital changes, which were not visible 2 months later. With expanding indication for CsA use, an increasing number of neurotoxic cases are to be expected.
