Abstract: context and objective: salivary gland tumor management requires long-term follow-up because of tumor indolence and possible late recurrence and distant metastasis. adenoid cystic carcinoma (acc) accounts for 10-15% of such tumors. the aim here was to evaluate surgical and clinical management, staging and follow-up of acc patients in one academic institution. design and setting: retrospective study at head and neck service, universidade estadual de campinas. methods: data on 21 patients treated between 1993 and 2003 were reviewed. management utilized clinical staging, histology and imaging. major salivary gland tumor extent was routinely assessed by preoperative ultrasonography. diagnosis, surgery type, margin type (negative/positive), postoperative radiotherapy and recurrence (presence/absence) were evaluated. results: there were eleven major salivary gland tumors (52.3%), seven submandibular and four parotid. ten patients (47.7%) had minor salivary gland acc (all in palate), while the submandibular was the most frequently affected major one. diagnoses were mostly via fine-needle aspiration (fna) and incision biopsy. frozen sections were used for six patients. there was good ultrasound/fna correlation. sixteen (76%) had postoperative radiotherapy. one (4.7%) died from acc and five now have recurrent disease: three (14.2%) locoregional and two (9.5%) distant metastases. conclusion: adenoid cystic carcinoma has locally aggressive behavior. in 21 cases, of acc, the facial nerve was preserved in all except in the few with gross tumor involvement. treatment was defined from physical examination, imaging, staging and histology.

Abstract: background: the objectives of this study are to analyze the frequency and the histopathological features of the villitis of unknown etiology (vue) in placentas of pregnancies with hypertensive disorders and of small-for-gestational-age infants (sga). methods: two hundred and thirteen placentas from pregnancies without clinical or laboratorial evidence of infection were studied. these cases were subdivided according to: a) maternal condition in: non-complicated pregnancy (ncp)- 151 cases, pregnancy-induced hypertension (pih)- 37 and sustained chronic hypertension (sch)- 25 and b) newborn weight in: small for gestational age (sga)- 38 cases and adequate for gestational age (aga)- 175. of these placentas, 81 belong to the random sample, which was used to determine the frequency of vue in the population studied. eight blocks were taken from placental parenchyma and the histological sections were stained with hematoxylin and eosin. frequency tables of categorical data were analyzed using the chi- square test and fisher test; statistical significance was considered for p< 0.05. results: the frequency of vue in the placentas was 30.8% in the random sample, 39% in ncp, 29.7% in pih, 32% in sch, 34.2% in sga infants and 37.1% in aga infants. placentas of pregnancies with hypertensive disorders were more affected by villitis with parenchymatous component (pih - 27.0%, sch - 28.0%). this lesion was also the predominant villitis in the placentas of the sga infants (31.5%). in contrast, in placentas of ncp and aga infants, the principal kind of villitis was basal, not associated to a parenchymatous component (16.5% and 14.8% respectively). in the majority of the cases the villitis was mild. conclusion: in the population studied, the frequency of vue is high (around 30%). the lesion occurs in a similar frequency in placentas from ncp, pih, sch, sga and aga infants, but basal villitis not associated to a parenchymatous component affects mainly the placentas of ncp and aga infants.
Nucleolar Organizer Regions (NORs)

Abstract: counts of nucleolar regions (nors) demonstrated by a silver staining technique in paraffin sections, have been used to distinguish between benign and malignant lesions. agnors were studied in 24 biopsies from oral cavity (5 cases of normal oral mucosa, 5 of pseudocarcinomatous hyperplasia and 14 of squamous cell carcinoma, subdivided according to degree of differentiation: 5 grade 1, 5 grade 2 and 4 grade 3) to find whether they were helpful in distinguishing pseudocarcinomatous hyperplasia due to chronic parasitic infections from squamous cell carcinoma. two methods of counting agnors were used: (a) a simpler one which counts nucleolar clusters (agnu) and satellite agnors and the other (b) counting all individual agnors, including those within agnus. in both methods the lowest mean values were observed for grade 3 carcinoma, while the highest belonged to grade 2 carcinoma. the simpler method (a) was the most useful because agnu counts showed significant difference when pseudocarcinomatous hyperplasia was compared with grade 1 and 2 carcinomas, which are the most difficult to discriminate from it. however the overlapping of values render the technique of limited use in individual cases.
Vilosite de etiologia desconhecida em placentas de gesta es com hipertens o arterial e de gesta es com recém-nascidos pequenos para a idade gestacional

Revista da Associa??o Médica Brasileira , 2003,
Abstract: OBJETIVOS: Analisar a freqüência da vilosite de etiologia desconhecida (VED) e suas características histológicas em placentas de gesta es com hipertens o arterial materna e de gesta es com recém-nascidos (RN) pequenos para a idade gestacional. MéTODOS: Foram estudadas 213 placentas de m es e RN sem evidências clínicas ou sorológicas de infec o. Estas placentas foram subdivididas conforme a condi o materna em: normotensas - 151 casos, doen a hipertensiva específica da gravidez (DHEG) - 37 e hipertens o cr nica - 25 e, de acordo com o peso do RN, em: pequenos (PIG)- 38 casos e adequados para a idade gestacional (AIG) - 175. Destas placentas, 81 pertenciam a uma amostra aleatória, que foi utilizada para determinar a freqüência de VED na popula o estudada. Foram retirados oito fragmentos do parênquima placentário e as sec es histológicas foram coradas por HE. Para análise estatística foram utilizados os testes de qui-quadrado e exato de Fisher, sendo p < 0.05 considerado significante. RESULTADOS: A freqüência de VED nas placentas foi de 30,8% na amostra aleatória, 39% nas normotensas, 29,7% nas gesta es com DHEG, 32% nas hipertensas cr nicas, 34,2% nos RN PIG e 37,1% nos RN AIG. Nas placentas de gesta es com hipertens o arterial predominou a vilosite com componente parenquimatoso (DHEG - 27%, hipertens o cr nica - 28%). Este tipo de vilosite também foi a mais comum nas placentas dos RN PIG (31,5%). Em contraste, a vilosite basal sem o componente parenquimatoso predominou nas placentas de normotensas (16,5%) e de RN AIG (14,8%). A maioria das vilosites era de intensidade leve. CONCLUS ES: Na popula o estudada, a freqüência de VED é alta, em torno de 30%. A VED ocorre com freqüências semelhantes em placentas de normotensas, de gesta es com DHEG ou hipertens o cr nica e em RN PIG e AIG, porém a vilosite basal sem o componente parenquimatoso é mais comum em normotensas e RN AIG. é possível que este tipo de vilosite seja resultante de uma estimula o antigênica diferente daquela da vilosite com componente parenquimatoso.

Valuation and Risk Assessment of a Portfolio of Variable Annuities: A Vector Autoregression Approach  [PDF]
Albina Orlando, Gary Parker
Journal of Mathematical Finance (JMF) , 2018, DOI: 10.4236/jmf.2018.82023
Abstract: This paper focuses on assessing the financial position of an insurer issuing a portfolio of Variable Annuities (VAs). Two multivariate models for the underlying and the interest rate are considered. The first model uses a single total rate of return for the basket of assets. The second one, jointly models the rates of return on the n assets in the basket. For simplicity, the insurer is assumed to be able to implement a static hedging programme to manage the risk. As an example, a homogeneous portfolio of VAs with GMDB and GMMB guarantees offering different investment opportunities to the policyholders is studied. The insurer can choose to rebalance the basket of assets regularly or not. Results for these two cases are presented.

Abstract: Albanian-Yugoslav relations after the end of World War Two characterize with significant Yugoslavimpact on Albanian internal and external politics; from then on the Yugoslav communists planned to integrate Albania into the Yugoslav Federation. Albanian government, led by Enver Hoxha, in 1945 faced two very important challenges: consolidation of the government and international recognition of this government. Therefore, an alliance with Yugoslavia was more than necessary for Albanian government. In this situation, Tito was keen to annex Albania as soon as possible before Western Powers or Russia would interfere this plan. Hoxha and most of the ACP (Albanian Communist Party) leadership were ready to give up Albania’s sovereignty and to integrate the country into Yugoslavia. The Yugoslav political elites were convinced that the question of Kosova could be resolved only with the integration of Albania into Yugoslavia. According to its plans, immediately after the integrationKosova would be united with the Albanian Republic within Yugoslavia.
