Atipias de Células Escamosas de Significado Indeterminado (ASCUS): estudo de 208 Casos

Objetivos: avaliar aspectos clínicos, colposcópicos e acompanhamento citológico de quadros classificados como atipias de células escamosas de significado indeterminado (ASCUS). Métodos: foram analisados retrospectivamente 208 casos de ASCUS diagnosticados entre 1996 e 1998 e tabulados quanto a idade, queixas clínicas, colposcopia e seguimento. Resultados: a relação ASCUS:lesão intra-epitelial escamosa foi de 1:1,2, confirmando adequado controle de qualidade. Pacientes com menos de 35 anos corresponderam a 72,6% dos casos. Um grande número não tinha queixas clínicas (36,5%). Nos casos em que foi realizada colposcopia (n = 58), a zona de transformação atípica foi observada em 60%. A subclassificação das ASCUS em provavelmente displásico (D), provavelmente reativo (R) e não-determinado (U) indicou predominância do primeiro (65%). O acompanhamento de 86 pacientes mostrou que, após 3 a 6 meses (média de 4,5 meses), em 12,5% foi possível detectar citologicamente uma lesão intra-epitelial escamosa. Conclusão: com base nos resultados deste trabalho foi possível concluir que as ASCUS incidem em mulheres jovens, com queixas clínicas corriqueiras e apresentam correlação colposcópica positiva. Nestes casos o acompanhamento citológico se faz imprescindível para esclarecimento de lesão intra-epitelial escamosa subjacente ou subseqüente.

SEMICLASSICAL ESTIMATE OF THE COULOMB-EXCITATION OF THE GIANT-DIPOLE RESONANCE IN PB-208

A semiclassical approach to study pure Coulomb excitation of Pb-208 giant dipole isovector resonance is examined. We consider medium energy projectiles and assume the target excitation to be described by a simple Goldhaber-Teller model. It is shown that the main features concerning the angular distribution are obtained in the angular range described by the model and an estimate is made of the pure Coulomb dipole contribution to the measured cross sections.

Covenanters of South Carolina Collection - Accession 208 - M92 (118)

The Covenanters of South Carolina Collections consists of a "Sketch of the Covenanters of Rocky Creek, South carolina About 1750 to 1840" by Miss Mary Elder, 1886 as dictated to her by her father Mr. Matthew Elder, Yorkville, SC. Also included is an undated genealogical sketch of William Stinson (Stevenson) (1752-1809) who was a covenanter from Rocky Creek, SC and a "History of Fishing Creek Presbyterian Church by Mrs. Frank Hicklin" that was written ca. 1958. The Fishing Creek Presbyterian Church was organized ca. 1752.

Cross-sectional observational study of 208 patients with non-classical urea cycle disorders

Urea cycle disorders (UCDs) are inherited disorders of ammonia detoxification often regarded as mainly of relevance to pediatricians. Based on an increasing number of case studies it has become obvious that a significant number of UCD patients are affected by their disease in a non-classical way: presenting outside the newborn period, following a mild course, presenting with unusual clinical features, or asymptomatic patients with only biochemical signs of a UCD. These patients are surviving into adolescence and adulthood, rendering this group of diseases clinically relevant to adult physicians as well as pediatricians. In preparation for an international workshop we collected data on all patients with non-classical UCDs treated by the participants in 20 European metabolic centres. Information was collected on a cohort of 208 patients 50% of which were ≥ 16 years old. The largest subgroup (121 patients) had X-linked ornithine transcarbamylase deficiency (OTCD) of whom 83 were female and 29% of these were asymptomatic. In index patients, there was a mean delay from first symptoms to diagnosis of 1.6 years. Cognitive impairment was present in 36% of all patients including female OTCD patients (in 31%) and those 41 patients identified presymptomatically following positive newborn screening (in 12%). In conclusion, UCD patients with non-classical clinical presentations require the interest and care of adult physicians and have a high risk of neurological complications. To improve the outcome of UCDs, a greater awareness by health professionals of the importance of hyperammonemia and UCDs, and ultimately avoidance of the still long delay to correctly diagnose the patients, is crucial.
