Germinação de sementes e emergência de plântulas de Oenocarpus minor Mart. (Arecaceae)

O presente trabalho teve como objetivo avaliar a influência da temperatura e do substrato na germinação, bem como determinar a profundidade ideal de semeadura para emergência de plântulas de Oenocarpus minor Mart. Utilizou-se o delineamento experimental inteiramente casualizado, em esquema fatorial 3x4 (temperatura x substrato), com três repetições de 30 sementes cada. As sementes foram colocadas no interior de caixas plásticas contendo substrato umedecido com água destilada e mantidas em câmaras de germinação à temperatura constante e com fotoperíodo de 12 horas. Para a emergência, foram usadas 4 repetições de 24 sementes, distribuídas em bandeja plásticas, com plantmax e vermiculita, em 0; 2 e 4 cm de profundidade de semeadura, mantidas em casa de vegetação. Baseado nos resultados obtidos, os substratos mais adequados para a germinação de sementes foram a areia e a vermiculita, e a melhor temperatura foi a de 30ºC. Profundidade superior a 2 cm é inadequada para a semeadura de Oenocarpus minor Mart.

Papillary cystoadenoma lymphomatosum (Warthin-like) of minor salivary glands

Papillary cystadenoma lymphomatosum is a benign salivary gland tumor most frequently located in the parotid gland (Warthin"s tumor). Its presentation in other major, or in minor, salivary glands is rare. Clinically, it manifests as a slow growing tumor, fluctuant on palpation due to its cystic morphology. The treatment of choice is complete excision with wide tumor-free margins. We present a 73-year-old female patient with an asymptomatic tumor of 8 years evolution in the right posterior area of the hard palate. We performed surgical excision and a biopsy, which was reported as papillary cystadenoma lymphomatosum. During the post-operative examination carried out after 3 weeks, it was observed that the lesion had recurred. The lesion was re-operated, performing the excision with CO2 laser and including the periosteum to ensure complete resection of the tumor. At 10 months follow-up, there was no recurrence of the lesion. This article includes a review of this condition and discusses its most important clinical and pathologic features and therapeutic approaches.

Impact of unbalanced minor route versus major route karyotypes at diagnosis on prognosis of CML.

Major route additional cytogenetic aberrations (ACA) at diagnosis of chronic myeloid leukaemia (CML) indicate an increased risk of progression and shorter survival. Since major route ACA are almost always unbalanced, it is unclear whether other unbalanced ACA at diagnosis also confer an unfavourable prognosis. On the basis of 1348 Philadelphia chromosome-positive chronic phase patients of the randomized CML study IV, we examined the impact of unbalanced minor route ACA at diagnosis versus major route ACA on prognosis. At diagnosis, 1175 patients (87.2 %) had a translocation t(9;22)(q34;q11) and 74 (5.5 %) a variant translocation t(v;22) only, while a loss of the Y chromosome (-Y) was present in addition in 44 (3.3 %), balanced or unbalanced minor route ACA each in 17 (1.3 %) and major route ACA in 21 (1.6 %) cases. Patients with unbalanced minor route ACA had no significantly different cumulative incidences of complete cytogenetic remission or major molecular remission and no significantly different progression-free survival (PFS) or overall survival (OS) than patients with t(9;22), t(v;22), -Y and balanced minor route karyotypes. In contrast, patients with major route ACA had a shorter OS and PFS than all other groups (all pairwise comparisons to each of the other groups: p ≤ 0.015). Five-year survival probabilities were for t(9;22) 91.4 % (95 % CI 89.5-93.1), t(v; 22) 87 % (77.2-94.3), -Y 89.0 % (76.7-97.0), balanced 100 %, unbalanced minor route 92.3 % (72.4-100) and major route 52.2 % (28.2-75.5). We conclude that only major route, but not balanced or unbalanced minor route ACA at diagnosis, has a negative impact on prognosis of CML.
