Analysis of the Relationship between Type II Diabetes Mellitus and Parkinson's Disease: A Systematic Review.

In the early sixties, a discussion started regarding the association between Parkinson's disease (PD) and type II diabetes mellitus (T2DM). Today, this potential relationship is still a matter of debate. This review aims to analyze both diseases concerning causal relationships and treatments. A total of 104 articles were found, and studies on animal and "in vitro" models showed that T2DM causes neurological alterations that may be associated with PD, such as deregulation of the dopaminergic system, a decrease in the expression of peroxisome proliferator-activated receptor-gamma coactivator-1α (PGC-1α), an increase in the expression of phosphoprotein enriched in diabetes/phosphoprotein enriched in astrocytes 15 (PED/PEA-15), and neuroinflammation, as well as acceleration of the formation of alpha-synuclein amyloid fibrils. In addition, clinical studies described that Parkinson's symptoms were notably worse after the onset of T2DM, and seven deregulated genes were identified in the DNA of T2DM and PD patients. Regarding treatment, the action of antidiabetic drugs, especially incretin mimetic agents, seems to confer certain degree of neuroprotection to PD patients. In conclusion, the available evidence on the interaction between T2DM and PD justifies more robust clinical trials exploring this interaction especially the clinical management of patients with both conditions.

Acute cytomegalovirus infection associated with pulmonary embolism treated successfully with rivaroxaban: case report.

Severe life-threatening thromboembolism may be caused exclusively by the presence of an acute CMV infection or due to the association of this agent and other thrombogenic factors. We report a case of an immunocompetent young female patient who presented a pulmonary embolism associated with acute CMV infection. The patient did not have any other apparent cause of thrombosis. She was successfully treated with rivaroxaban for 6 months without further episodes. To the best of our knowledge, this is the first report of a pulmonary embolism associated with CMV treated with a direct oral anticoagulant. The current case report calls attention to the importance of signs and symptoms of thromboembolism among patients with CMV. Direct oral anticoagulants can potentially bring the same benefits to treat pulmonary embolism associated with CMV as those observed in patients not infected.

Crohn's disease versus Yersinia enterocolitica infection - case report - a difficult differential diagnosis / Doença de Crohn's × Yersinia enterocolitica - um difícil diagnóstico diferencial - relato de caso

ABSTRACT The aim of this report is to present an unusual case of Crohn's disease affecting the terminal ileum; whose principal differential diagnosis was Yersinia enterolocolitica infection, as the histological features of the resected ileum was common to both diseases. We also describe how the infectious etiology was discarded and the implications for the patient follow-up.

RESUMO O objetivo desse relato é analisar um caso incomum de doença de Crohn, cujo diagnóstico diferencial, com possível infecção por Yersinia enterocilítica, foi dificultado pela presença de alterações histológicas das duas doenças. Descrevemos como foi realizada a exclusão de causas infecciosas e as implicações no acompanhamento do paciente.

A non-living, effective model for microvascular training

Abstract Purpose: To introduce a nonliving microvascular training model based on vessels diameter and feasibility. Methods: We dissected ten oxen tongues, and divided the pedicles into three-thirds: proximal, middle and distal. We measured the external vessels diameter in all regions. We performed a descriptive statistical analysis. Three students (two beginner level and one intermediate level) performed this training. We evaluated the confidence, according Likert scale. Results: We dissected all oxen tongues, each tongue showed two parallel pedicles. Each pedicle was located at 1.5 - 2.0 cm from the midline. Proximal median artery and vein diameter were 3.9 ± 0.7, and 5.04 ± 1.44mm, respectively. In the middle third, the mean artery diameter was 3.3 ± 0.4mm, and the vein diameter was 3.5 ± 0.9mm. The distal third showed a mean artery diameter of 2.0 ± 0.42mm, and a vein diameter of 2.4 ± 0.82mm. The students performed ten anastomoses. This study showed a higher confidence level (CL) (p=0.03) than the pre training CL assessment. Conclusion: This study suggested a feasible non-animal model for microsurgical training process for beginners and intermediate trainees.

Initial experience of endoscopic submucosal dissection in Brazil to treat early gastric and esophagheal cancer: a multi-institutional analysis.

OBJECTIVE: This study aimed to evaluate the feasibility and clinicopathological characteristics of early gastric and esophageal cancers treated with endoscopic submucosal dissection (ESD) at five centers in Brazil. METHODS: Five centers in Brazil reported their initial experience with ESD. The cases reported had already been collected by each center before pooled analysis. RESULTS: Were resected 62 gastric lesions; 52(83,8%) of the gastric lesions were well-differentiated adenocarcinoma, 31(50%) from the antrum, 24 (38.7%) type IIa. 51 (82.2%) lesions had en-block resection with three showing lateral margin compromise. Concerning invasion, 25 (40.3%) tumors were M1. Mean tumor diameter was 18.9 mm (range, 0.6-5.0 cm) and mean procedure duration was 119.45 minutes. Gastric perforation occurred in three (4.8%) patients. Mean follow-up duration was 11.3 months, with two local recurrences and one death from pneumonia Seven months after treatment. Of the 16 esophageal lesions resected, 14 (87.4%) were squamous cell carcinoma, 10 (62.5%) were located proximally and 8 (50.0%) type IIa. Mean tumor diameter was 23.8 mm (range, 6-60 mm). Thirteen (81.2%) lesions had en-block resection with five cases of lateral margin compromise. Eight (50.0%) lesions were M1. Mean procedure duration was 78 minutes (range, 20-150 min). Complications included pneumomediastinum in two (12.5%) patients and stenosis in one (6.2%). Mean duration of follow-up was 8.6 months, with no local recurrence despite the presence of lateral margin compromise. CONCLUSION: Different centers in Brazil feasibly perform ESD with a high success rate.

EUS-guided percutaneous endoscopic gastrostomy for enteral feeding tube placement.

BACKGROUND: Patients without adequate abdominal-wall transillumination are at a high risk of developing complications after PEG. OBJECTIVE: We evaluated the feasibility and utility of EUS to guide PEG in patients lacking abdominal-wall transillumination. DESIGN: Single-center case series. SETTING: Tertiary-referral center. PATIENTS: Six patients who lacked adequate abdominal-wall transillumination and 2 patients with a large laparotomy scar deemed to be at high risk of developing complications after PEG. INTERVENTIONS: Patients underwent EUS-guided PEG and deployment of a standard enteral feeding tube. MAIN OUTCOME MEASUREMENTS: Technical success and complication rates. RESULTS: PEG was successful under EUS guidance in 5 of 8 patients. Causes of failure included an inadequate EUS window because of a prior Billroth 1 gastrectomy in one and suspected bowel interposition in 2 patients. There were no complications. LIMITATIONS: A small number of patients, uncontrolled study, and short follow-up period. CONCLUSIONS: This technique may facilitate deployment of PEG in patients who lack adequate abdominal-wall transillumination.

EUS for locoregional staging of prostate cancer--a pilot study.

BACKGROUND: This was a pilot study on EUS for locoregional evaluation of prostate cancer. OBJECTIVE: Our purpose was to evaluate radial and linear-array EUS in locoregional prostate cancer staging. DESIGN, SETTING, PATIENTS: From April to December 2005, 23 patients were referred to the Department of Urology with a confirmed or highly suspected diagnosis of prostate cancer on the basis of cytohistologic examination of fragments obtained by transrectal US-guided biopsy or transuretheral means. After institutional review board approval, informed consent was obtained from all patients. INTERVENTION: An endosonographer and a radiologist with expertise in prostate imaging performed radial and linear EUS examinations without knowledge of the stage of prostate cancer of the referred patients. MAIN OUTCOME MEASUREMENTS: Systematic prostatic evaluation by EUS. All patients underwent prostatectomy, and the surgical specimens were analyzed and correlated with EUS findings. RESULTS: Mean age was 65.91 years, and the mean prostate-specific antigen level was 27.73 ng/mL. Histopathologic study of the surgical specimen revealed adenocarcinoma in 20 of 23, atypical adenomatous hyperplasia in 2 of 23, and sclerosing adenosis in 1 of 23. Staging by EUS for T stage showed different sensitivity (S), specificity (E), and accuracy (A) according to the degree of tumor invasiveness as follows: T1 (S: 51.3%, E: 53.2%, A: 49.1%); T2 (S: 100%, E: 91.67%, A: 95%); T3 (S: 100%, E: 100%, A: 100%). In 3 (3/23) patients EUS did not find a defined lesion, but the surgical specimen showed T1 stage cancer. EUS staging for N stage showed 62.5% sensitivity, 58.33% specificity, and 60% accuracy for N0. Regarding N1, 58.3% sensitivity, 52.50% specificity, and 60% accuracy were found. LIMITATIONS: Uncontrolled, nonrandomized study. CONCLUSIONS: EUS presented high sensitivity, specificity, and accuracy for prostate cancer staging.

Contaminaçäo da dieta enteral em ambiente nosocomial / Contamination of enteral diets in nosocomial environment

O trato gastrointestinal é comparativamente resistente aos germes veiculados pela dieta, mas estudos recentes sugerem que infecçöes hospitalares podem ter início nesta rota. Uma investigaçäo efetuada com dietas industrializadas, preparadas com cuidados satisfatórios de assepsia, e armazenadas por até 24 horas, pesquisou contaminantes aeróbios e anaeróbios porventura presentes nestas preparaçöes. A sistemática de cultivo abrangeu amostras de 0h, 8h, e 24h, sendo que estas últimas foram alternativamente conservadas em temperaturas ambiente ou em geladeira. A cultura inicial já revelou 50% de positividade microbiana, porém parte desta contaminaçäo era devida as espécies de bacilos näo patogênicos. Após 8h e 24h os índices observados revelaram-se de ordem de 90%, ainda com presença expressiva de bacilos Gram negativos, ao lado de ratas bactérias Gram positivas. Durante o período da realizaçäo desta pesquisa näo se observaram episódios significativos de diarréia ou febre, que pudessem ser atribuídos à contaminaçäo relatada, nem se registraram situaçöes de bacteremia ou choque séptico em qualquer paciente sob nutriçäo enteral. Esta ausência de repercussöes clínicas para os achados laboratoriais em questäo näo é inesperada, e sugere baixas contagens para os microorganismos em tela, as quais näo atingiram concentraçöes críticas. Näo obstante, um grau de atençäo maior deverá ser dedicado ao controle de qualidade das dietas enterais, especialmente quando as bactérias Gram negativas multi-resistentes forem identificadas, ou quando a populaçäo tratada constitui-se de pacientes muito debilitados ou imunologicamente comprometidos
