ABSTRACT

A hiperplasia hipofisária é definida como um aumento não neoplásico no número de um dos tipos de células presentes na hipófise. Ela pode ocorrer por um processo fisiológico ou patológico. O hipotireoidismo primário prolongado é uma das causas patológicas desta condição, e ocorre devido a perda do feedback negativo. O objetivo desse relato foi demonstrar a presença de hiperplasia hipofisária em um paciente masculino com características corporais sugestivas de acromegalia. A investigação laboratorial confirmou a presença de hipotireoidismo primário e descartou a acromegalia. Foi instituído tratamento com levotiroxina, levando a regressão da hiperplasia hipofisária. Esse caso ilustra a importância de uma investigação apropriada em pacientes com hiperplasia hipofisária, bem como discute a fisiopatologia e o tratamento dessa doença.


Pituitary hyperplasia is defined as a non-neoplastic increase in the number of one of the cell types present in the pituitary gland. It can occur by a physiological or pathological process. Prolonged primary hypothyroidism is one of the pathological causes of this condition and occurs due to the lack of negative feedback. The objective of this report was to demonstrate the presence of pituitary hyperplasia in a male patient with body characteristics suggestive of acromegaly. Laboratory investigation confirmed the presence of primary hypothyroidism and ruled out acromegaly. Treatment with levothyroxine was instituted, leading to regression of pituitary hyperplasia. This case illustrates the importance of an appropriate investigation in patients with pituitary hyperplasia, as well as discussing the pathophysiology and treatment of this disease.

ABSTRACT

Abstract Introduction Reactive hyperplastic lesions develop in response to a chronic injury simulating an exuberant tissue repair response. They represent some of the most common oral lesions including inflammatory fibrous hyperplasia, oral pyogenic granuloma, giant cell fibroma, peripheral ossifying fibroma, and peripheral giant cell lesions. Objective The incidence of those lesions was investigated in an oral pathology service, and the clinical characteristics, associated etiological factors, concordance between the clinical and histopathological diagnostic was determined. Methods A total of 2400 patient records were screened from 2006 to 2016. Clinical features were recorded from biopsy reports and patients' files. Results A total of 534 cases of reactive hyperplastic lesions were retrieved and retrospectively studied, representing 22.25% of all diagnoses. The most frequent lesion was inflammatory fibrous hyperplasia (72.09%), followed by oral pyogenic granuloma (11.79%), giant cell fibroma (7.30%), peripheral ossifying fibroma (5.24%), and peripheral giant cell lesions (3.55%). Females were predominantly affected (74.19%), the gingiva and alveolar ridge were the predominant anatomical site (32.89%), and chronic traumatism was presented as the main etiological factor. The age widely ranges from the 1st decade of life to the 7th. Clinically, the reactive hyperplastic lesions consisted of small lesions (0.5-2 cm) and shared a strong likeness in color to the oral mucosa. The concordance between the clinical and histopathological diagnostic was high (82.5%). Conclusion Reactive hyperplastic lesions had a high incidence among oral pathologies. The understanding of their clinical features helps to achieve a clearer clinical and etiological diagnosis, and the knowledge of factors related to their development. This may contribute to adequate treatment and positive prognosis.


Resumo Introdução As lesões hiperplásicas reativas se desenvolvem em resposta a uma lesão crônica que estimula uma resposta acentuada de reparo tecidual. Elas representam uma das lesões orais mais comuns, inclusive hiperplasia fibrosa inflamatória, granuloma piogênico oral, fibroma de células gigantes, fibroma periférico ossificante e lesão periférica de células gigantes. Objetivo A incidência dessas lesões foi investigada em um serviço de patologia bucal e as características clínicas, os fatores etiológicos associados e a concordância entre os diagnósticos clínico e histopatológico foram determinados. Método Foram selecionados 2.400 registros de pacientes entre 2006 e 2016. As características clínicas foram registradas a partir de laudos de biópsia e dos prontuários dos pacientes. Resultados Um total de 534 casos de lesões hiperplásicas reativas foram recuperados e retrospectivamente estudados, representando 22,25% de todos os diagnósticos. A lesão mais frequente foi hiperplasia fibrosa inflamatória (72,09%), seguida por granuloma piogênico oral (11,79%), fibroma de células gigantes, (7,30%), fibroma periférico ossificante (5,24%) e lesão periférica de células gigantes (3,55%). O sexo feminino foi predominante (74,19%), a gengiva e a crista alveolar foram o local anatômico predominante (32,89%) e o traumatismo crônico foi demonstrado como o principal fator etiológico. A idade variou desde a 1ª década de vida até a 7ª. Clinicamente, as LHR consistiram em pequenas lesões (0,5 a 2 cm) que apresentaram uma forte semelhança de cor com a mucosa oral. A concordância entre o diagnóstico clínico e histopatológico foi alta (82,5%). Conclusão As lesões hiperplásicas reativas apresentaram alta incidência entre as patologias bucais. A compreensão das características clínicas ajuda na realização de um diagnóstico clínico e etiológico mais claro, bem como determinar os fatores relacionados ao seu desenvolvimento. Dessa forma contribui para um tratamento adequado e um prognóstico positivo.

ABSTRACT

Objective: to assess post-angioplasty myointimal hyperplasia in iliac artery of rabbits treated with extract of Moringa oleifera leaves. Methods : we conducted a randomized trial in laboratory animals for five weeks of follow-up, developed in the Vivarium of Pharmaceutical Technology Laboratory of the Universidade Federal da Paraíba. We used rabbits from the New Zealand breed, subjected to a hypercholesterolemic diet and angioplasty of the external iliac artery, randomized into two groups: M200 Group (n=10) - rabbits treated with 200mg/kg/day of Moringa oleifera leaves extract orally; SF group (n=10) - rabbits treated with 0.9% saline orally. After five weeks, the animals were euthanized and the iliac arteries prepared for histology. Histological sections were analyzed by digital morphometry. Statistical analysis was performed using the Student's t test. The significance level was 0.05. Results : there was no significant difference in myointimal hyperplasia between M200 and SF groups when comparing the iliac arteries submitted to angioplasty. Conclusion : there was no difference of myointimal hyperplasia between groups treated with saline and Moringa oleifera after angioplasty.

ABSTRACT

Intravascular papillary endothelial hyperplasia (IPEH) is an unusual reactive lesion of vascular origin, which rarely occurs in the oral cavity. Pathogenetically, is it divided into true, mixed and extra‑vascular types. We report a case of extra‑vascular IPEH of the lower lip in 54‑year‑old female patient. Patient gives history of trauma 4 months back with lesion developing at the site to trauma. The lesion was 3 cm × 4 cm in size with soft to firm in consistency. Histologically, it is characterized by an exuberant papillary endothelial cell proliferation toward the lumen of an enlarged blood vessel from the area of an organizing thrombus. The lesion was surgically excised under local anesthesia. The patient was followed for 1‑year with no evidence of recurrence. This paper discusses the various aspects of IPEH of the oral cavity such as pathogenesis, clinical features, histopathology treatment, and prognosis.

ABSTRACT

Las anomalías dentofaciales funcionales o disgnacias esqueléticas afectan a la población colombiana por encima de un 70%, y son causa de alteraciones sistémicas nutricionales por la maloclusión y la deglución atípica presente, así como en el desarrollo y funcionamiento orgánico por la disnea o inclusive apnea del sueño concomitante, y no menos importante, el impacto psicosocial, que se deriva en baja autoestima, depresión, síndrome maniaco-depresivo y/o suicidio. La cirugía ortognática, como única opción real y definitiva para tal morbilidad, sigue siendo declinada por los planes obligatorios de salud territoriales, debido a su errónea categorización de procedimiento estético, que inherentemente obliga a los pacientes a acceder a ellos de manera particular. A continuación se presenta el tratamiento inmediato de una disgnacia clase III con hiperplasia condilar activa, mediante abordaje “surgery first”, manejado por el Servicio de Otorrinolaringología y Cirugía Maxilofacial del Hospital de San José (Bogotá - Colombia)...


Dentofacial functional or disgnacias skeletal abnormalities affect the Colombian population above 70%, causing systemic nutritional alterations by the malocclusion and atypical swallowing present, alterations in development and organic performance by dyspnea, or even sleep apnea concomitantly, and not least, the psychosocial impact resulting in low self-esteem, depression, manic-depressive syndrome and/ or suicide. Orthognathic surgery as the only real and definitive option for such morbidity is being declined by mandatory territorial health plans because of its erroneous categorization of cosmetic procedure that inherently requires patients to access them in particular. Below an immediate treatment of a disgnacia class III with condylar hyperplasia active approach “Surgery First” managed by the Service of Otolaryngology and Maxilofacial Surgery of the San José Hospital (Bogotá - Colombia)...

ABSTRACT

Little evidence is available about the related factors for colorectal hyperplastic polyps in Taiwan. The aim of this study was to explore the prevalence of rectosigmoid hyperplastic polyps and to determine the related factors. Medical center in Taichung city, Taiwan Retrospective hospital-based, cross-sectional study. We analyzed the medical records of all subjects receiving periodic health examination at one medical center in Taichung city in Taiwan from 2001 to 2004. A total of 4413 subjects were enrolled in this study. All subjects underwent a 60-cm flexible sigmoidoscopic examination and laboratory survey. Prevalence of hyperplastic Polyps and related factors.There were 2444 men [55.4%] and 1969 women [44.6%]. The mean age was 49.3 years [standard deviation 12.3, range from 20 to 87]. The overall prevalence of hyperplastic polyps was 5.5%, with higher prevalence in men than in women [6.9% Vs 3.7%, p < 0.001]. After controlling for the other co-variates, multivariate logistic regression model showed that the related factors for hyperplastic polyps were increasing age [OR = 1.03, 95% CI = 1.02 -1.05, p < 0.001], male gender [OR =1.79, 95% CI = 1.31 - 2.46, p < 0.001], generalized obesity [OR = 1.59, 95% CI = 1.10 - 2.28, p = 0.012], and smoking [OR = 1.40, 95% CI = 1.02 - 1.93, p = 0.038]. These findings reveal that increasing age, male gender, generalized obesity and smoking are the related factors for rectosigmoid hyperplastic polyps

ABSTRACT

OBJECTIVE: To evaluate intimal thickening secondary to stent placement or to insertion of the delivery system without stent placement in pig carotid arteries. METHODS: Stents were placed in the right common carotid arteries of 7 pigs, and 7 other control pigs underwent only insertion of the delivery system without stent placement. Uninjured contralateral common carotid arteries of the two groups were also used as controls. Samples of arterial tissue, obtained from the area adjacent to the distal segment of the stent four weeks after placement, underwent morphometric analysis. Morphometric data were compared with findings for arterial samples from injured arteries of the control group and uninjured contralateral arteries of the two groups. The unpaired Mann-Whitney U test and the Wilcoxon t test for nonparametric samples were used for statistical analysis. RESULTS: Greater intimal thickening was found in the group in which stents were placed (p=0.008). Changes in luminal area and media layer were not significantly different between the two groups. The comparison of contralateral carotid arteries of the two groups revealed significant changes in intimal and luminal areas. No statistically significant changes were found in medial layer area. CONCLUSIONS: All arteries that underwent stent placement showed intimal thickening without changes in the tunica media at four weeks. Dissection and insertion of the delivery system without stent placement was associated with a lesser degree of intimal thickening.


OBJETIVO: analisar o espessamento intimal adjacente ao implante de um stent em artérias carótidas de suínos e aquele secundário à simples manipulação da artéria pelo introdutor do dispositivo. MÉTODOS: sete suínos receberam o implante de um stent na artéria carótida comum direita, sob dissecção direta do vaso e sete animais controles sofreram manipulação arterial, com o sistema introdutor, sem o implante do stent. As artérias carótidas comuns contralaterais não lesadas, dos dois grupos, também foram utilizadas como controle. Realizada a análise morfométrica de amostras de tecido arterial, obtidas junto ao segmento distal do stent, quatro semanas após o implante. Os achados morfométricos foram comparados com amostras arteriais oriundas das carótidas lesadas, no grupo controle, e das carótidas contralaterais não lesadas dos dois grupos. A análise estatística foi realizada através do teste de Mann-Whitney e do teste T de Wilcoxon, para amostras não-paramétricas (p<0,05). RESULTADOS: observado um maior espessamento intimal no grupo submetido ao implante de stent (p=0,008). As áreas luminais e da camada média não apresentaram alterações significativas, entre os dois grupos. Quando os dois grupos foram comparados às suas respectivas artérias carótidas contralaterais, foram encontradas alterações significativas nas mensurações da área intimal e do lúmen arterial. Não houve alterações estatisticamente significativas na área da camada média. CONCLUSÕES: todas as artérias submetidas ao implante do stent apresentaram espessamento intimal, sem alterações na camada média, quatro semanas após o implante de um stent. A simples manipulação arterial provocou espessamento intimal.

ABSTRACT

OBJETIVO: Avaliar as lesões proliferativas que se desenvolvem na mucosa gástrica de ratos Wistar após modelo específico de refluxo duodeno-gástrico.MÉTODOS: Foram utilizados 75 ratos adultos machos divididos em três grupos experimentais: o grupo I (controle) submetido a gastrotomia na parede posterior do estômago glandular (25 animais); o grupo II (RDG), foi submetido a gastrojejunoanastomose látero-lateral na parede posterior do estômago glandular (25 animais) e o grupo III (RDG-P) submetido a gastrojejunoanastomose látero-lateral na parede posterior do estômago glandular, com secção e fechamento da alça (25 animais). Os animais foram observados durante 36 semanas, após o que foram realizados estudos macroscópicos e microscópicos da anastomose gastrojejunal, da região pré-pilórica e região escamosa do estômago. RESULTADOS: Os animais do Grupo I não apresentaram nenhum tipo de lesão. No grupo II observou-se 40% de lesões do tipo hiperplasia adenomatosa na anastomose e 12% de hiperplasia escamosa. No grupo III obteve-se 40% de hiperplasia adenomatosa na mucosa pré-pilórica, 72 % de hiperplasia adenomatosa na mucosa da anastomose, 20% de hiperplasia escamosa e 12 % de adenocarcinoma. CONCLUSÕES: O refluxo duodeno-gástrico induz a alta freqüência de lesões proliferativas na mucosa adjacente à anastomose gastrojejunal ou na mucosa pré-pilórica e o adenocarcinoma é um evento raro neste modelo experimental.

ABSTRACT

Los Oligoastrocitoma mixtos son una minoría (10 por ciento-19 por ciento) de los gliomas supratentoriales. Presentándose generalmente en adultos menores de 40 a¤os con leve predominío del sexo masculino. Su presentación más frecuente son las convulsiones. La presencia de gemistocitos en los gliomas se asocia con un curso clínico desfavorable. Los Oligoastrocitomas anaplásicos grado III con componente gemistoc¡ticos tiene una incidencia del 5 por ciento y una recurrencia de 40 por ciento-100 por ciento y estos pacientes cursan con una sobrevida de dos años, luego de la primera cirugía, aún con tratamiento adicional con radioterapia y/o químioterapia. Presentamos el caso de paciente femenino con 20 años quien debutó con cefalea y amaurosis. Al estudiarse, se diagnóstico tumor occipital derecho mixto, realizándose resección del mismo, la biopsia revelo Oligastrocitoma Anaplásico III (OMS) con importante componente gemistocítico. Egresada por mejoría clínica con tratamiento complementarío de radioterapia.

ABSTRACT

OBJETIVO: Descrever as lesões pulmonares em uma série de necropsias de pacientes com idade de até 15 anos, falecidos em unidade de terapia intensiva, submetidos ou não à nutrição parenteral total. MÉTODOS: Seis fragmentos de cada pulmão de 114 crianças foram corados por métodos de rotina. Dos prontuários foram obtidas informações referentes aos dados demográficos, clínicos e de terapêutica. Para a análise estatística, foi utilizado o Programa Statistical Package for the Social Sciences. RESULTADOS: Os 114 pacientes foram separados em dois grupos: 50 foram tratados com NPT contendo emulsão de lipídios e os 64 restantes, sem nutrição parenteral total. Os grupos eram semelhantes em relação ao sexo (p = 0,654), à idade (p = 0,682) e ao peso (p = 0,175), e apresentavam diferenças significativas no que tange às seguintes variáveis: tempo de internação (p = 0,000), prematuridade (p = 0,008) e tratamento com hemoderivados (p = 0,009). Todos foram submetidos à ventilação mecânica durante o período de internação. Na análise univariada, as lesões relacionadas à nutrição parenteral total foram: dano alveolar difuso (p = 0,022), fibrose pulmonar (p = 0,019), hiperplasia de pneumócitos (p = 0,004), microtromboembolismo (p = 0,047) e tromboflebite (p = 0,033). A análise multivariada, levando em consideração a prematuridade, o tempo de internação e a idade, mostrou que apenas a fibrose estava relacionada, de modo independente, ao uso da nutrição parenteral total. CONCLUSAO: Embora as lesões pulmonares tenham sido mais freqüentes em pacientes tratados com nutrição parenteral total, não foi possível concluir que essa tenha sido diretamente responsável pela origem das lesões, tendo em vista que co-fatores como prematuridade e tempo de internação influenciaram significativamente no seu aparecimento.

ABSTRACT

Intravascular papillary endothelial hyperplasia (intravascular angiomatosis) is a lesion which several authors regard as a reactive phenomenon associated with such vascular alterations as hemangiomas, hematomas, varix, thrombi or dilated vessels while others consider it a neoplasm. An extensive review of the literature and a discussion of the previously reported points of view with a report of six new oral cases (including the first such lesion associated with an oral hematoma) is presented. As it is demonstrated, this process starts as a thrombus formation with initial proliferation of endothelial cells and it ends as an endothelial nodule of main intravascular location. The importance of distinguishing this lesion from angiosarcoma is stressed and their differences discussed. We propose that the correct name for this entity is "Nodular Endothelial Hyperplasia".

ABSTRACT

Eighty hirsute women [Ferryman and Gallwey score >/= 8] who were referred to the endocrinology clinics of Shiraz university and ten control normal nonhirsute women were assessed in this study. Baseline 17-hydroxyprogesterone [17 OH PG], cortisol, stimulated 17-hydroxyprogesterone and cortisol after 30 minutes of cosyntropin [short acting ACTH] injection were measured for screening of late-onset congenital adrenal hyperplasia [LOCAH] during follicular phase. Baseline testosterone, Luteinizing hormone [LH], follicular stimulating hormone [FSH], thyroid stimulating hormone[TSH], prolactin [PRL] and dihydroepian drosterone sulfate [DHEA-So[4]] were also measured. The ovaries were visualized in 42 patients by sonography. Of the 80 hirsute women, 3 had late-onset CAH due to 21-Hydroxylase [21 OH] deficiency [3.8%], 43 women diagnosed as having Polycystic ovary syndrome [53.7%] and 34 women diagnosed as having idiopathic hirsutism [42.5%]

ABSTRACT

Com o aumento estimado da populaçäo idosa, observa-se a necessidade de o CD aprimorar seus conhecimentos a respeito dessa faixa etária, visto que näo é raro termos um paciente nessa situaçäo. Assim sendo, foi realizada uma pesquisa na Universidade Federal de Pelotas - RS, através de inquérito domiciliar, a qual visava obter alguns dados da condiçäo bucal dessas pessoas. A populaçäo estudada era de baixa renda, sendo a maioria do sexo feminino (64,3 por cento), com média de idade de 65 anos. Dos idosos, 64,6 por cento eram edentados totais e soemente 73,4 por cento destes faziam uso de aparelhos protéticos, sendo a maioria de prótese total superior. Foi observado grande número de portadores de candidíase, peridontite severa e hiperplasia no palato devido ao uso de prótese total com câmara de sucçäo. Eventualmente, também foram encontrados lígua saburrosa, língua fissurada, leucoplasia e outros

ABSTRACT

We present the case of a three year old girl who showed two adverse reactions to DPH, one of them a large cervical lymphatic hyperplasia, which responded to discontinuation of the drug. Laboratory tests were normal and histological examination showed non specific adenitis. We discuss this unusual case and the importance of the cervical adenopathy differential diagnosis

ABSTRACT

The evolution and phenotypic expression of mucosal lesions of the gastric stump were investigated in male rats submitted to gastric resection with reconstruction by the Bilroth II technique (biliopancreatic reflux - BPR) and by the Roux-en-Y procedure (without BPR). The animals were studied at 24, 36, 54 and 64 weeks after surgery. the phenotypic expression of the lesions was analyzed by immunohistochemical staining for pepsinogen isoenzyme 1 and by histochemical procedures for mucins. BPR was found to be responsible for the formation of adenomatous hyperplasia (AH) whose incidence and size increased with time. AH mainly consisted of gastric cells and always occurred in the transition of the gastrojejunal junction, and this site offers special conditions for the promoting effect of BPR to occur in full. In 101 rats submitted to BII procedures, 6 mucinous adenocarcinomas were diagnosed and this neoplasia expressed the phenotype of cells of the small intestine. The roux-en-Y procedure protects the gastric stump aginst the lesions observed in BII reconstruction
