Implica??es cognitivas, filosóficas e educativas do trabalho do patologista
Pena, Gil Patrus;Andrade-Filho, José de Souza;
Revista Brasileira de Educa??o Médica , 2006, DOI: 10.1590/S0100-55022006000200010
Abstract: establishing a pathological diagnosis requires complex mental processes including attention, perception, memory, planning and language, not always clearly understood by the pathologists themselves. little importance has been given to these important aspects of the pathological practice in spite of its profound implications for understanding the intricate processes involved in pathological diagnosis. in this paper, we present a theoretical basis for the diagnostic process. in the description of the cognitive mental processes such as attention, perception and memory we employ the concepts of luria and vygotskyy, emphasizing the cultural origins of these processes largely mediated by the language. the dichotomy between objectivity and subjectivity is approached through maturana's biology of knowledge. based on these concepts we present a theoretical planning strategy considering cognitive, communicative, and normative aspects as well as the performance of the pathologist in relation to the case, to the patient and to the assistant physician. finally, we present the educational implications arising from this model.
Adenocarcinoma em mucosa sinonasal expressando PSA e CDX-2: apresenta??o de um caso com ênfase no processo de decis?o diagnóstica quanto à origem do tumor
Pena, Gil Patrus;Andrade-Filho, José de Souza;Fonseca, Roberto Porto;
Jornal Brasileiro de Patologia e Medicina Laboratorial , 2009, DOI: 10.1590/S1676-24442009000200009
Abstract: in this report, we explore an unusual case of adenocarcinoma detected in the sinonasal mucous membrane in order to illustrate the diagnostic decision process in the immunohistochemical diagnosis. the patient is a 86-year-old man with an intranasal mass. in the immunohistochemical study, it was found expression for both psa and cdx-2, raising the divergent diagnostic possibilities of a prostatic adenocarcinoma metastasis or an intestinal type sinonasal adenocarcinoma. in search for a solution for this diagnostic dilemma, we tried to establish how these immunohistochemical markers could be confronted in a diagnostic decision by defining the qualities that good immunohistochemical markers consist of and how the panel markers may be compared as to these qualities and the diagnostic hypotheses. in this exercise, important aspects of the diagnostic process in pathology are revealed.

Abstract: wells? syndrome is a rare, benign, recurrent, inflammatory dermatosis affecting all age groups, with no sex predilection. its etiology and pathogenesis remain unknown. although its autonomous existence is questioned by some, wells? syndrome is a distinct disease entity diagnosed by the combination of a striking clinical picture, typical histological finding when associated to the clinical features, and a characteristic time course.

Abstract: the aim of this paper was to verify the sand fly species collected with malaise trap in the cities of divinópolis and pedra do indaiá, both located in minas gerais state. collections were carried out between november 2003 and october 2004. thirty two specimens were captured belonging to seven species: pintomyia monticola (costa lima), nyssomyia whitmani (antunes & coutinho), pintomyia christenseni (young & duncan), evandromyia cortelezzii (brèthes), sciopemyia sordellii (shannon & del ponte), pintomyia pessoai (coutinho & barretto) and psathyromyia aragaoi (costa lima).
Is Demodex really non-pathogenic?
PENA, Gil Patrus;ANDRADE FILHO, José de Souza;
Revista do Instituto de Medicina Tropical de S?o Paulo , 2000, DOI: 10.1590/S0036-46652000000300012
Abstract: although usually considered a non-pathogenic parasite in parasitological textbooks, demodex folliculorum has been implicated as a causative agent for some dermatological conditions, such as rosacea-like eruptions and some types of blepharitis. several anecdotal reports have demonstrated unequivocal tissue damage directly related to the presence of the parasite. however, this seems to be exceedingly rare, in contrast with the marked prevalence of this infestation. we have had the opportunity to observe one of such cases. a 38-year-old woman presented with rosacea-like papular lesions in her right cheek. histopathological examination revealed granulomatous dermal inflammation with a well-preserved mite phagocytized by a multinucleated giant cell. this finding may be taken as an evidence for the pathogenicity of the parasite, inasmuch as it does not explain how such a common parasite is able to produce such a rare disease.

Abstract: neurocysticercosis (ncc) is a common parasitic disease in our region, presenting diversity of neurological symptoms and signs. the present study has as primary objective an evaluation of the ncc's clinical and epidemiological profile within bahia state, by means of a prospective study of 220 patients diagnosed from march 1988 to march 1999, with a follow-up of six months. exams, such as computed cranial tomography scan (ct), cerebral spine fluid (csf) and electroencephalogram (eeg), were accomplished in three distinct moments of these patients' evolution: at starting or diagnostic point (zero time), at after-intervention period (one month after treatment), and at control period (six months after treatment).
Description of a new genus and new species of New World Phlebotominae (Diptera, Psychodidae)

Revista Brasileira de Entomologia , 2003, DOI: 10.1590/S0085-56262003000100010
Abstract: a new genus and new species of phlebotominae, edentomyia piauiensis (diptera, psychodidae) from a cave in piauí state, brazil, are described. this new genus belongs to phlebotomini, but its inclusion in any subdivision of this tribe depends on further study.

Istoadenoma do ducto biliar comum
Andrade Filho, José de Souza;Pena, Gil Patrus Mundim;Drummond, Domingos André F.;
Revista do Colégio Brasileiro de Cirurgi?es , 2000, DOI: 10.1590/S0100-69912000000600011
Abstract: biliary duct cystoadenomas are rare neoplasms, with about 120 cases described in the literature, including cystoadenomas and cystoadenocarcinomas. the authors report a case of cystoadenoma of the common bile duct in a 45-year-old woman with history of jaundice. ultrasound revealed a cystic mass located in the common bile duct. endoscopic retrograde cholangiopancreatography showed a negative filling defect in the proximal third of the common bile duct, a finding unique to our case. total excision of the mass, cholecystectomy and an end-total anastomosis with a t-tube choledochostomy, were performed. histological examination revealed a multicystic lesion with cavities lined by mucinous columnar non-ciliated epithelium, with surrounding densely cellular stroma resembling ovarian stroma. six years after surgery the patient is alive and well, with no complains referring to the hepatobiliary tract. no abnormalities are presently detected in the biliary tree, ultrasonographically.
