Abstract
BACKGROUND This systematic review integrated the available data published in the literature on Stafne's bone defect (SBD), considering the clinical, imaging and histopathological results. MATERIAL AND METHODS An electronic search was undertaken in six databases. Eligibility criteria were: articles in English, Spanish, and Portuguese describing case reports or case series of SBD, reported up to September/2021. Risk of bias was assessed using the Joanna Briggs Institute tool. RESULTS A total of 98 articles were retrieved, involving 465 individuals with SBD and were included for quantitative analysis. Mean age was 52.78 years (range: 11-89 years), with male predilection (n=374/80.85%). Radiographs were the most frequent imagiological exams (n=298/64.09%), followed by computed tomography (n=98/21.08%). SBD was more prevalent in the posterior mandible (n=361/93.77%) as a hypodense radiolucent lesion (n=250/77.40%). Mean size was 1.58 cm (range: 0.3-.8.0 cm). Two-hundred-and-two lesions (97.37%) were unilocular and 126 (91.97%) were classified as well-defined. Clinical symptoms were reported in 73 cases, while 68 cases (93.15%) were asymptomatic. Only 34 cases (12.32%) were submitted to histopathological examination. Mean follow-up time was 26.42 ±25.39 months. CONCLUSIONS SBD is more frequent in male patients in the fifth and sixth decade of life. Classic SBD is radiographically characterized as a single, unilocular and well-defined lesion in the posterior region of the jaw with a radiolucent/hypodense appearance.

Abstract
OBJECTIVE The aim of this study was to determine the prospective capacity and impact of donor risk index, preallocation survival outcomes following liver transplant, donor model for end-stage liver disease, and balance of risk on patients' 30-day survival after liver transplantation. METHODS We prospectively analyzed patient survival in a multicentric observational cohort of adult liver transplantation through the year of 2019 at the state of Paraná, Brazil. The receiver operating characteristic curve, the area under the curve, and the best cutoff point (i.e., the Youden's index) were estimated to analyze the prognostic value of each index. RESULTS In total, 252 liver transplants were included with an average model for end-stage liver disease score of 21.17 and a 30-day survival of 79.76%. The donor risk index was the only prognostic variable with no relation to patients' 30-day mortality model for end-stage liver disease and donor model for end-stage liver disease have no prognostic value on receiver operating characteristic curve, but preallocation survival outcomes following liver transplant, survival outcomes following liver transplant, and balance of risk presented good relationship with this observation. The cutoff value was estimated in 11-12 points for balance of risk and 9-12 for preallocation survival outcomes following liver transplant and survival outcomes following liver transplant. The 30-day survival for the group of transplants with scores up to 12 points (n=172) in all the three indexes was 87.79%, and for those transplants with scores higher than 12 it was 36.36%. CONCLUSIONS The 30-day survival is 79.76%, and balance of risk, survival outcomes following liver transplant, and preallocation survival outcomes following liver transplant are the good prognostic indexes. The cutoff value of 12 points has clinical usefulness to predict the post-liver transplantation results.

Abstract
OBJECTIVES To describe the use, complications and outcome of temporary tracheostomy tube placement as part of the management of acute upper airway obstruction in the postoperative period following multi-level airway surgery in patients with brachycephalic obstructive airway syndrome. MATERIALS AND METHODS Retrospective review of records of dogs surgically treated for brachycephalic obstructive airway syndrome that had a temporary tracheostomy tube placed in the postoperative period. RESULTS Forty-two dogs were included. Median duration of temporary tracheostomy tube placement was 2 days (range 1 to 7). The major complication rate was 83.3%, minor complication rate was 71.4%, resulting in an overall postoperative complication rate of 95.2%. The most common postoperative complications were tracheostomy tube obstruction (32/42), cough (25/42) and tracheostomy tube dislodgement (16/42). Temporary tracheostomy tube management was classified as successful in 97.6%. Dyspnoea was the most common clinical sign in the short-term postoperative follow-up period, while dyspnoea and increased upper respiratory tract noise were the most common clinical sign in the long term. The median duration of follow-up was 251 days. CLINICAL SIGNIFICANCE In an appropriate clinical setting, placement of temporary tracheostomy tubes following multi-level airway surgery for brachycephalic obstructive airway syndrome is a useful strategy to manage postoperative airway obstruction, carrying a low mortality rate, and with a complication rate similar to that found in previous reports.

Abstract
Root fractures resulting from dental trauma involve dentin, cementum and pulp. The present study aimed to demonstrate the importance of cone-beam computed tomography (CBTC) and bioceramics in the correct planning and intervention of a horizontal root fracture case in tooth 11 with late treatment in an 18-year-old patient. Clinical and radiographic examinations revealed tooth displacement, pain on vertical percussion and images suggestive of a horizontal root fracture. Pulp necrosis was diagnosed and CBTC was requested for treatment planning. Subsequently, endodontic treatment was performed using a bioceramic apical plug. A 2-year follow-up indicated the absence of root resorption and normal periodontal and periapical tissues. It was concluded that endodontic treatment associated with the use of bioceramics and the aid of CBTC is an effective therapeutic option in cases of permanent horizontal root fractures. Key words:Bioceramics, Cone-beam computed tomography, dental Injuries, root fracture.

Abstract
UNLABELLED We evaluate 38 elderly women who had received long-term denosumab treatment after stopping the drug. Taking into account the gain during treatment and the loss after stopping treatment, they lost 35.5% of the total gain in the spine, 44.6% of the total gain in the femoral neck, and 103.3% in the total hip. INTRODUCTION Denosumab (DMAb) is a soluble inhibitor of the receptor activator of nuclear factor-kappaB ligand (RANKL) and, therefore, does not incorporate into the bone matrix. Consistently, DMAb discontinuation is associated with reversal of the effects attained with treatment. PURPOSE The aim of this study is to assess changes in BMD after a year of discontinuation of DMAb in a group of postmenopausal women treated with DMAb for 7 or 10 years. Secondly, is to evaluate the occurrence of fragility fractures. METHODS Women who had participated in the FREEDOM study and its extension were invited to participate in this follow-up study. BMD at LS and hip and spine X-rays were obtained. Results were compared to the last value obtained while in treatment to assess changes after discontinuation. RESULTS Thirty-eight women, mean age: 81 ± 3.4 years completed study procedures; none had received bisphosphonates after stopping DMAb. Mean gap time between DMAb last dose and the follow-up visit was 17 months (range 16-20 months). Bone mineral density (BMD) decreased significantly in all regions: - 8.1% in LS, - 6% in FN, and - 8.4% in TH. Five (5/38, 13.15%) patients had a fragility fracture, one suffered a wrist fracture, and four experienced vertebral fractures. Three patients suffered one vertebral fracture and one of them had two vertebral fractures. Laboratory results showed the following mean values: CTX = 996 ± 307 pg/ml (normal values 550 ± 226 pg/ml); osteocalcin = 55.2 ± 18.6 ng/ml (normal value 42 ng/ml); and 25 OH vitamin D = 23.7 ± 6.9 ng/ml. CONCLUSION Our results describe the rapid bone loss occurring after cessation of denosumab treatment. Further studies are needed to assess if patients have a higher risk of fracture after stopping DMAb and if so, which patients have the highest risk, and assess the role of transitioning to bisphosphonates in the long term.

Abstract
Detection and analysis of virulence-associated genes (VAGs) of avian pathogenic Escherichia coli (APEC) may be helpful to distinguish pathogenic from commensal faecal strains (AFEC). The aim of this study was to characterise 120 isolates of avian Escherichia coli, comprising 91 APEC (from diseased birds) and 29 AFEC (from healthy chickens), collected in Brazil. Phylogenetic analysis and in vivo pathogenicity testing was performed on 38 VAGs. The VAGs iucD, iutA, iroN, fepC, ompT, cvi and hlyF were statistically associated with medium and high pathogenicity (MP/HP) strains. A minimal group of seven VAGs may be required to accurately discriminate pathogenic and non-pathogenic avian strains of E. coli in Brazil.

Abstract
Although Trypanosoma cruzi, the parasite that causes Chagas disease, can be transmitted via organ transplantation, liver and kidney transplantation from infected donors may be feasible. We describe the outcomes of 32 transplant recipients who received organs from 14 T. cruzi seropositive donors in the United States from 2001 to 2011. Transmission was confirmed in 9 recipients from 6 donors, including 3 of 4 (75%) heart transplant recipients, 2 of 10 (20%) liver recipients and 2 of 15 (13%) kidney recipients. Recommended monitoring posttransplant consisted of regular testing by PCR, hemoculture, and serology. Thirteen recipients had no or incomplete monitoring; transmission was confirmed in five of these recipients. Four of the five recipients had symptomatic disease and all four died although death was directly related to Chagas disease in only one. Nineteen recipients had partial or complete monitoring for T. cruzi infection with weekly testing by PCR, hemoculture and serology; transmission was confirmed in 4 of 19 recipients with no cases of symptomatic disease. Our results suggest that liver and kidney transplantation from T. cruzi seropositive donors may be feasible when the recommended monitoring schedule for T. cruzi infection is followed and prompt therapy with benznidazole can be administered.

Abstract
BACKGROUND Orthotopic liver transplantation is the best therapeutic modality for patients with end stage of liver disease. Minimization of death, while waiting for the procedure, involves accurate priorization according to clinical status and appropriate allocation of donor livers. AIM The mortality analysis in the liver waiting list in Paraná state, PR, Brazil. METHODS Were analyzed the data on all patients (n = 65) who were registered on the liver waiting list during a 32 months period in the state of Paraná, southern Brazil. RESULTS The death rated in waiting list was 41,5% (n = 27). No statistic difference was observed regarding the MELD/MELD-Na scores between the group who died (19,88/21,6) and not died (17,28/19,47). MELD-Na predicted a higher mortality, especially in the subgroup of patients with intermediate severity of disease (class B) predicted by the CTP score. CONCLUSION It´s critical the shortage of donor organs in our region, waiting list mortality rate far exceeds the inherent risk of a liver transplant, especially among patients with lower MELD scores. It´s desirable to use an aggressive protocol of expanded criteria donors, split liver and living donor transplant.

Abstract
UNLABELLED Hemodialyzed patients have decreased bone strength not completely characterized. We evaluated bone microarchitecture in hemodialysis patients and compared it to that of subjects without renal disease by high-resolution peripheral quantitative computed tomography (HR-pQCT). Hemodialysis patients have a marked decreased in cortical density, thickness, and area with significant reduction in trabecular parameters that correlated with the severity of secondary hyperparathyroidism only in women. INTRODUCTION Although fracture risk is greatly increased in dialysis patients, the corresponding decreased in bone strength has not been completely characterized. METHODS We evaluated volumetric bone mineral density (vBMD) and bone microstructure by HR-pQCT at the distal radius and tibia in 50 hemodialyzed (HD) patients (30 females, mean age 53.2 ± 6 years and 20 males, mean age 59.1 ± 11 years) and 50 sex- and age-matched controls. RESULTS At the distal radius HD, women showed a 29% reduction in total and trabecular density and trabecular bone volume fraction (p < 0.0001) compared to controls. Trabecular number was reduced by 25% (p < 0.0001), while trabecular separation was increased by 51%. Cortical thickness (-40%, p < 0.0001) and cortical area (-42%, p < 0.0001) were the parameters most reduced, while compact density was the parameter least reduced (-15%, p < 0.0001). Similar findings were found at the tibia. In HD men, HR-pQCT at the distal radius and tibia showed a reduction in volumetric density and microstructure parameters to a lesser extent than in women. In the hemodialyzed group, cortical thickness at the radius was negatively correlated with age both in women and men. At the distal radius and tibia, we found significant negative correlations between Log iPTH and total alkaline phosphatase with cortical vBMD(r = -0.48, p < 0.01; r = -0.69, p < 0.001), thickness (-0.37, p < 0.05; r = -0.60, p < 0.001), and area ((r = -0.43, p = 0.02; r = -0.65, p < 0.001) but only in women. CONCLUSION We conclude that hemodialysis patients have a marked decreased in cortical density, thickness, and area with significant reduction in trabecular parameters that correlated with the severity of secondary hyperparathyroidism only in women.

Abstract
O transplante hepático inter vivos adulto expandiu as possibilidades terapêuticas para pacientes com insuficiência hepática terminal. A necessidade de um volume hepático adequado que será retirado do doador e necessário ao receptor limita sua utilização em alguns casos. Apresentamos um caso em que se utilizou dois lobos esquerdos de dois doadores vivos no intuito de prover parênquima hepático suficiente ao receptor.

Abstract
Alphitobius diaperinus, conhecido como cascudinho, é encontrado abundantemente nas instalações avícolas, e acarreta prejuízos zootécnicos e sanitários na avicultura industrial mundialmente. As formas de controle deste besouro estão baseadas exclusivamente no uso de inseticidas para os quais já existem vários relatos de populações resistentes forçando o emprego de métodos alternativos como o controle biológico, interferindo no ciclo de vida do inseto. Este estudo avaliou, em condições de laboratório, a mortalidade de larvas e adultos de A. diaperinus frente a diferentes temperaturas de aquecimento (45º, 50º, 55º e 60º C) e resfriamento (-10º, -13º e -18º C), na presença de maravalha (PM) e ausência de maravalha (AM), através do tempo letal de 100% dos insetos (TL100) em minutos em cada temperatura. A TL100 de larvas e adultos em 45º C foi de 36 e 38 AM e 42 e 57 PM, em 50º C foram 15 e 11 AM e 19 e 16 PM, para 55º C foi de 8 e 9 AM e 12 PM e em 60º C foi de 5 e 6 AM e 11 e 9 PM. Já em -10º C variou de 57 e 60 AM e 70 e 75 PM, em -13º C levou 52 e 55 AM e 60 e 64 PM e em -18º C levou 42 e 43 AM e 51 e 52 PM. Em todas as temperaturas avaliadas houve mortalidade dos insetos em tempo consideravelmente rápido e métodos de controle, através da temperatura, devem levar em consideração esses pontos para referência.

Abstract
OBJETIVO: Correlacionar a dosagem sérica pré-operatória e pós-operatória de interleucina-6 (IL-6) e interleucina-10 (IL-10) entre pacientes submetidos à colecistectomia laparotômica versus videolaparoscópica. MÉTODOS: De um total de 20 pacientes, 18 foram incluídos no estudo, sendo nove submetidos à colecistectomia laparoscópica e os outros nove utilizando a técnica laparotômica. As concentrações séricas de IL-6 e IL-10 foram dosadas em ambos os grupos. As amostras de sangue foram obtidas nos tempos de 24 horas no pré-operatório, quatro, 12 e 24 horas após o procedimento. Os grupos foram comparados em relação à idade, sexo, índice de massa corpórea (IMC), tempo de anestesia e de operação. RESULTADOS: Não houve diferenças significativamente estatísticas entre os grupos relacionadas à idade, sexo, IMC, tempo de anestesia e de operação. A comparação entre a colecistectomia laparotômica e laparoscópica demonstrou diferenças estatísticas nos níveis de IL-6 no tempo 12 horas após operação (218,64pg/ml laparotômica versus 67,71pg/ml laparoscópica, p=0,0003) e IL-10 no tempo de 24 horas após o procedimento (24,46pg/ml aberta versus 10,17pg/ml laparoscópica, p <0,001). CONCLUSÃO: Houve aumento das dosagens de interleucinas-6 e 10 após o trauma cirúrgico. Ocorreu aumento significativo dos níveis das interleucinas analisadas no grupo laparotômico em comparação com o grupo laparoscópico.

Abstract
We present a case of a 42-year-old man with abdominal pain, obstructive jaundice and a mass in the second portion of the duodenum, near the papillary region. The patient was operated and the histological study of the specimen returned duodenal gangliocytic paraganglioma (a rare submucosal benign tumor of the duodenum). We also describe, after revision of the literature, the pathology, the diagnosis and its treatment.

Abstract
After decades of controversy surrounding the therapeutic validity of pancreas transplantation, the procedure has become accepted as the preferred treatment for selected patients with type 1 diabetes mellitus. Between January 2001 and January 2008, 100 patients underwent pancreatic transplantation at our center: 88 simultaneous pancreas-kidney transplantation and 12 pancreas transplantations alone. Pancreas graft management of the exocrine drainage technique involved enteric drainage in 8 (all simultaneous pancreas-kidney) and the bladder in 92 cases. The recipient systemic venous system was used for the pancreas graft venous effluent in all cases. Our overall results have shown that the number of functioning pancreatic grafts was 64 of 100. Graft losses were: rejection (n = 8), venous thrombosis (n = 9), arterial thrombosis (n = 1), or surgical complications such as anastomotic leak (n = 3), perigraft infection (n = 10), pancreatitis of the graft (n = 5). Most cases of pancreatitis (80%) had preservation times exceeding 18 hours. Despite surgical and immunosuppressive complications, our impression was that pancreas transplantation was a highly effective therapy for diabetes mellitus. After 7 years of the program and 100 transplantations, we believe that there is a major role for transplantation in diabetes management.

Abstract
OBJETIVO: Relatar nossa experiência com 100 transplantes de pâncreas realizados em um período de sete anos. MÉTODOS: Entre janeiro de 2001 e janeiro de 2008, 100 pacientes foram submetidos a transplante de pâncreas em nosso serviço, sendo 88 transplantes de pâncreas e rim simultâneo (TPRS) e 12 transplantes de pâncreas isolado (TPI). Todos foram transplantes primários. O manejo da porção exócrina do enxerto pancreático envolveu drenagem entérica em oito casos (todos TPRS) e a bexiga em 92 casos. O sistema venoso sistêmico do receptor foi utilizado para a drenagem venosa do enxerto em todos os casos. Nossos últimos 30 pacientes submetidos à TPRS não receberam terapia de indução independentemente do painel imunológico.Os pacientes TPRS receberam basiliximab e TPI receberam timoglobulina nos casos induzidos. Imunossupressão de manutenção foi realizada com tacrolimus, micofenolato mofetil e corticóides. O volume de perfusão do enxerto pancreático foi limitado a 800ml da solução de Celsior ou UW. RESULTADOS: Demonstram que os enxertos ainda funcionantes são atualmente 64 dos 100 realizados. Perda do enxerto foi causada por: rejeição (oito pacientes), trombose venosa (nove pacientes), trombose arterial (um paciente) Complicações cirúrgicas encontradas: fístula anastomótica (tres pacientes), infecção peri-enxerto (10 pacientes), pancreatite do enxerto (cinco pacientes). A Rejeição foi observada com menos freqüência nos TPRS (5/92) que nos TPI (3/12). A morte ocorreu em 24 pacientes. CONCLUSÃO: Nossa impressão é que o transplante de pâncreas é altamente efetivo como terapia para o diabetes mellitus apesar da morbidade do procedimento.

Abstract
INTRODUÇÃO: atualmente cerca de 90% das operações anorretais são realizadas em regime ambulatorial. A técnica anestésica é fator fundamental na busca de reduzido tempo de internação, agilidade no ambiente cirúrgico e redução de custos nestes procedimentos. Não há consenso na literatura sobre qual o melhor tipo de anestesia para essas operações. OBJETIVO: comparar o tempo de ocupação de sala cirúrgica em pacientes submetidos a operações anorretais através da técnica de raquianestesia com bupivacaína 0,5% isobárica comparada com a técnica de anestesia venosa com propofol associada ao bloqueio perianal local com lidocaína a 2% e bupivacaína 0,5%. MÉTODOS: Foram incluídos 99 pacientes divididos em 2 grupos: grupo I (raquianestesia), composto por 50 pacientes e grupo II (anestesia combinada), composto por 49 pacientes. Foram estudados os procedimentos cirúrgicos e o tempo de procedimento anestésico-cirúrgico, e medida indireta da ocupação da sala cirúrgica. RESULTADOS: Não houve diferença estatística significativa entre os grupos estudados em relação ao tipo de procedimento cirúrgico, sexo e idade. O tempo médio do procedimento anestésico-cirúrgico, no grupo I foi de 53,1 min e de 44,08 min no grupo II (p=0,034). CONCLUSÕES: As duas técnicas estudadas foram eficazes. Houve menor tempo de procedimento anestésico-cirúrgico nos pacientes operados com anestesia combinada, com significância estatística.

Abstract
AIM To report the simultaneous endodontic and surgical treatment of a tooth associated with Oehlers type III dens invaginatus and a persistent periapical lesion, which comprised root-end resection, root-end filling and application of a calcium hydroxide barrier placed on the resected dentine surface. SUMMARY Three root canals were identified in a tooth with a type III dens invaginatus, which presented with a necrotic pulp, wide foraminal opening and extensive periapical lesion, and with a previous history of acute abscess, intracanal exudate and fistula. After root canal preparation followed by intracanal application of calcium hydroxide pastes, the clinical-pathological status persisted. After periapical curettage and root-end resection, the root canals were filled, followed by root-end filling with Sealer 26 mixed with zinc oxide powder to a clay-like consistency. Calcium hydroxide paste was then applied over the exposed dentinal surface forming a covering over the root apex. At the 20-month follow-up examination the patient had no symptoms and no fistula; advanced periapical bone repair was obvious on the radiograph. KEY LEARNING POINTS Because of the variable morphology and extent of invagination, type III dens invaginatus represents a challenge for conventional treatment, often leading to the need for a surgical approach. Sealer 26 thickened with zinc oxide powder provided satisfactory clinical properties for use as a root-end filling material. Application of a calcium hydroxide barrier over the resected root-end is a potential treatment option to encourage tissue repair.

Abstract
Significant early bleeding is one of the surgical complications following simultaneous pancreas-kidney transplantation that has historically shaped the procedure. The consequence, exploratory laparotomy, carries high morbidity levels and elevated costs for the health system. Angiographic intervention is already a common procedure for the treatment of late, but not early, vascular complications. We describe a case of an early vascular complication that was successfully treated with angiographic embolization in a to simultaneous pancreas-kidney transplant patient.

Abstract
A genome-wide scan was conducted for visceral leishmaniasis (VL) in Brazil. Initially, 405 markers were typed in 22 multicase pedigrees (28 nuclear families; 174 individuals; 66 affected). Non-parametric multipoint analysis detected nine chromosomal regions with provisional evidence (logarithm of the odds (LOD) scores 0.95-1.66; 0.003<P<0.018) for linkage. To confirm linkage, 132 individuals (43 affected) from 19 independently ascertained families were genotyped across these regions. Three regions (6q27, 7q11.22 and 17q11.2-q21.3) retained evidence (LOD scores 1.08, 1.34, 1.14; P=0.013, 0.007, 0.011) for linkage. To determine which genes contribute to linkage at 17q11.2-q21.3, 80 single nucleotide polymorphisms were genotyped in 98 nuclear families with 183 affected individuals. Family-based association test analysis indicated associations at two chemokine genes, CCL1 and CCL16, that lie 1.6 Mb apart, show some extended linkage disequilibrium with each other, but each lie within different clusters of candidate CCL genes. Multiple genes may therefore contribute to the linkage peak for VL at 17q12.

Abstract
OBJETIVO: Esta pesquisa tem por objetivo quantificar a perda de energia calórica que ocorre ao realizarmos uma laparotomia com exposição de alças intestinais à atmosfera em ratos; determinar a perda termodinâmica representada por watts/m² em função da superfície peritoneal exposta do animal e discutir meios de tratamento para a perda de calor. MÉTODO: Foram utilizados 30 ratos machos, Wistar, distribuídos em cinco grupos de seis animais cada, com idade de 8 a 9 semanas, com o peso entre 200 e 220g. No grupo A ou grupo controle, os animais foram submetidos a anestesia inalatória. No grupo B, os ratos foram submetidos a uma laparotomia mediana com exposição das alças intestinais. Nos grupos C, D e E, os ratos foram submetidos a uma laparotomia mediana com exposição das alças intestinais e tratados respectivamente, por gaze úmida, gaze seca e empacotamento com filme de poliéster. RESULTADOS: Observou-se uma significativa perda de energia calórica quando se realiza uma laparotomia com exposição das alças intestinais em ambiente não controlado, da ordem de 620,72 kJ/m² A análise da perda termodinâmica, em função da superfície corpórea exposta do rato, apresentou um valor de 382,97 W/m². CONCLUSÕES: Na avaliação dos diferentes tipos de tratamento utilizados para prevenir a perda de calor corpóreo, ficou evidente que a utilização do filme de poliéster (PVC) foi o método mais efetivo na conservação do calor, em relação à gaze seca e, ou úmida respectivamente.

Abstract
AIM To report the repair of an extensive periapical lesion of endodontic origin, following nonsurgical treatment. SUMMARY Clinical and radiographic examination revealed an extensive periapical lesion related to tooth 22, extending from the distal surface of tooth 21 to the mesial surface of 26. The patient reported a previous history of dental trauma involving this quadrant and had been under orthodontic treatment for a year. Intraoral examination revealed an asymptomatic bony hard swelling, mainly confined to the palate. During root canal exploration irregular walls associated with 3 mm of apical calcification were noted. After apical patency was obtained 1 mL of bloody serous exudate was drained. Intracanal aspiration provided a further 2 mL of yellow serous exudate. Following biomechanical preparation, a dressing of calcium hydroxide with anaesthetic solution was applied and replaced four times over a period of 12 months. The clinical-pathological picture demonstrated resolution of the lesion during this period of time. The 14-month clinical and radiographic examinations revealed normal bony contour and a significant resolution of the maxillary radiolucency. KEY LEARNING POINTS Periapical lesions of endodontic origin may develop asymptomatically and become large. Proper biomechanical preparation followed by calcium hydroxide medication renewed periodically represents a nonsurgical approach to resolve extensive inflammatory periapical lesions.

Abstract
OBJETIVO: Estudar comparativamente a cicatrização e a formação de aderências em baço de ratos submetidos à trauma operatório e corrigidos utilizando octil-2-cianoacrilato (DE) e fio de poliglecaprone 25 (CA). MÉTODO: 30 ratos machos Wistar foram separados em três grupos de 10 animais, anestesiados de acordo com as normas do COBEA, submetidos à laparotomia xifopúbica e com uma tesoura Metzenbaum, foi realizada uma lesão esplênica com 4mm de profundidade, na borda anti-hilar do pólo inferior do baço. No Grupo CA, suturou-se a lesão com pontos contínuos de poliglecaprone 25; no Grupo DE, com octil-2-cianoacrilato e no Grupo CO, não houve sutura. Após 14 dias, os ratos foram submetidos à eutanásia e as aderências anotadas em protocolo próprio. O estudo anatomopatológico foi realizado nas colorações hematoxilina-eosina e Picro-Sirius, sendo do tipo fechado, duplo-cego. RESULTADOS: O Grupo DE apresentou menos aderências e menor reação de cicatrização tipo corpo estranho que o CA. Ambos mostram quantidade semelhante de colágeno jovem e maduro. CONCLUSÕES: O octil-2-cianoacrilato provocou menos aderências macroscópicas que o fio de poliglecaprone corado e não induziu cicatrização com reação de corpo estranho, mostrando-se efetivo no reparo das lesões traumáticas esplênicas, em ratos.

Abstract
Genome-wide scans were conducted for tuberculosis and leprosy per se in Brazil. At stage 1, 405 markers (10 cM map) were typed in 16 (178 individuals) tuberculosis and 21 (173 individuals) leprosy families. Nonparametric multipoint analysis detected 8 and 9 chromosomal regions respectively with provisional evidence (P<0.05) for linkage. At stage 2, 58 markers from positive regions were typed in a second set of 22 (176 individuals) tuberculosis families, with 22 additional markers typed in all families; 42 positive markers in 50 (192 individuals) new leprosy families, and 30 additional markers in all families. Three regions (10q26.13, 11q12.3, 20p12.1) retained suggestive evidence (peak LOD scores 1.31, 1.85, 1.78; P=0.007, 0.0018, 0.0021) for linkage to tuberculosis, 3 regions (6p21.32, 17q22, 20p13) to leprosy (HLA-DQA, 3.23, P=5.8 x 10(-5); D17S1868, 2.38, P=0.0005; D20S889, 1.51, P=0.004). The peak at D20S889 for leprosy is 3.5 Mb distal to that reported at D20S115 for leprosy in India. (151 words).

Abstract
The region of conserved synteny on mouse chromosome 11/human 17q11-q21 is known to carry a susceptibility gene(s) for intramacrophage pathogens. The region is rich in candidates including NOS2A, CCL2/MCP-1, CCL3/MIP-1alpha, CCL4/MIP-1beta, CCL5/RANTES, CCR7, STAT3 and STAT5A/5B. To examine the region in man, we studied 92 multicase tuberculosis (627 individuals) and 72 multicase leprosy (372 individuals) families from Brazil. Multipoint nonparametric analysis (ALLEGRO) using 16 microsatellites shows two peaks of linkage for leprosy at D17S250 (Z(lr) score 2.34; P=0.01) and D17S1795 (Z(lr) 2.67; P=0.004) and a single peak for tuberculosis at D17S250 (Z(lr) 2.04; P=0.02). Combined analysis shows significant linkage (peak Z(lr) 3.38) at D17S250, equivalent to an allele sharing LOD score 2.48 (P=0.0004). To determine whether one or multiple genes contribute, 49 informative single nucleotide polymorphisms were typed in candidate genes. Family-based allelic association testing that was robust to family clustering demonstrated significant associations with tuberculosis susceptibility at four loci separated by intervals (NOS2A-8.4 Mb-CCL18-32.3 kb-CCL4-6.04 Mb-STAT5B) up to several Mb. Stepwise conditional logistic regression analysis using a case/pseudo-control data set showed that the four genes contributed separate main effects, consistent with a cluster of susceptibility genes across 17q11.2.

Abstract
OBJETIVOS: Analisar a epidemiologia e a conduta nos ferimentos cervicais. MÉTODO: Foram analisados 487.128 prontuários de pacientes que ingressaram no Serviço de Emergência do Hospital Universitário Cajuru no período de 01/1996 a 06/2001. Destes, selecionaram-se 378 pacientes com ferimentos cervicais. Foram excluídos 153 que apresentavam lesões associadas e 14 por óbito no atendimento inicial. O estudo foi feito , assim, em 191 pacientes com lesões cervicais exclusivas. Avaliou-se a localização da ferida, o mecanismo de trauma, o comprometimento do platisma, sinais e sintomas, a hora de admissão e a conduta empregada. RESULTADOS: Cento e sessenta e quatro (86%) pacientes eram masculinos. A média de idade foi de 28 anos (10-72). Noventa (47%) ferimentos foram por arma de fogo (FAF) e 88 (46%) por arma branca (FAB). O principal horário de admissão foi entre 20 e 04 horas. Quanto à localização, 53% das lesões foram à esquerda, 45% à direita e 2% medianos; 36% em zona I, 55% em zona II e 9% em zona III. Em 101 o ferimento penetrou o platisma: cinqüenta e um (50%) apresentaram sinais e sintomas clínicos e receberam conduta operatória. As lesões vasculares foram as mais encontradas (20). Houve 24 (47%) cervicotomias não-terapêuticas. O tratamento conservador foi empregado em 41 (45%) casos de acordo com os exames físico e complementares. CONCLUSÕES: Homens jovens são mais acometidos quanto aos ferimentos cervicais. Estes ocorrem mais freqüentemente na zona II, e a incidência dos FAF e FAB foi equivalente. É adequado um manejo mais seletivo em relação aos ferimentos cervicais, devendo o manejo da zona II adequar-se à disposição de recursos dos serviços de trauma.

Abstract
Familial aggregation, high relative risk to siblings, and segregation analysis, suggest genetic control of visceral leishmaniasis in Brazil. Class II gene effects in mice, and high circulating tumour necrosis factor alpha in humans, provide reasons to target HLA. Fifteen polymorphic markers across 1.03 Mb (DQB1 to TNFa) were genotyped (87 multicase families; 638 individuals). Model-based parametric analyses using single-point combined segregation and linkage in COMDS, or multi-point linkage in ALLEGRO, failed to detect linkage. Model-free nonparametric affected sibling pair (SPLINK) or NPL(all) score (ALLEGRO) analyses also failed to detect linkage. Information content mapping confirmed sufficient marker information to detect linkage. Analysis of simulated data sets demonstrated that these families had 100% power to detect NPL(all) scores of 5 to 6 (>LOD4; P < 0.00001) over the range (7% to 61%) of age-related penetrances for a disease susceptibility gene. The extended transmission disequilibrium test (TDT) showed no consistent allelic associations between disease and the 15 loci. TDT also failed to detect significant associations between extended haplotypes and disease, consistent with failure to detect significant linkage disequilibrium across the region. Linkage disequilibrium between adjacent groups of markers (HLADQ/DR; 82-1/82-3/-238bpTNFA; LTA/62/TNFa) was not accompanied by significant global haplotype TDT associations with disease. The data suggest that class II/III regions of HLA do not contain major disease gene(s) for visceral leishmaniasis in Brazil.

Abstract
Black moulds are a heterogeneous group of darkly pigmented (dematiaceous) fungi, widely distributed in the environment, that occasionally cause infection in humans. The clinical spectrum of infection includes mycetomas, chromoblastomycosis, sinusitis, and superficial, cutaneous, subcutaneous and systemic phaeohyphomycosis. During the last 2 years, there have been reports of infection caused by black moulds in previously healthy individuals and in immunocompromised patients, including an outbreak of fungemia in hospitalized patients. Molecular analysis of strains obtained from patients and from the environment has suggested a common nosocomial source. In addition, data on antifungal susceptibility tests have become available. Surgical excision and antifungal therapy (usually itraconazole) remain the standard treatment for these infections.
