A Case of Chronic Mesenteric Ischemia imitating Crohn's disease

Objectives: We present an atypical case of chronic mesenteric ischemia with weight loss as only clinical manifestation and endoscopic findings imitating Crohn´s disease. Materials and Methods: A CT Angiography of abdomen confirmed the diagnosis of mesenteric ischemia after total occlusion of celiac trunk and superior mesenteric artery. Results: The patient died due to severe sepsis, as a result of extended bowel infarction. Conclusions: The diagnosis of chronic mesenteric ischemia requires a high degree of clinical suspicion and can be life-saving if early conducted.

'Abnormal vertical growth' : A disorder threatening the viability of the Australian macadamia industry

'Abnormal vertical growth' (AVG) was recognised in Australia as a dysfunction of macadamia (Macadamia spp.) in the mid-1990s. Affected trees displayed unusually erect branching, and poor flowering and yield. Since 2002, the commercial significance of AVG, its cause, and strategies to alleviate its affects, has been studied. The cause is still unknown, and AVG remains a serious threat to orchard viability. AVG affects both commercial and urban macadamia. It occurs predominantly in the warmer-drier production regions of Queensland and New South Wales. An estimated 100,000 orchard trees are affected, equating to an annual loss of $ 10.5 M. In orchards, AVG occurs as aggregations of affected trees, affected tree number can increase by 4.5% per year, and yield reduction can exceed 30%. The more upright cultivars 'HAES 344' and '741' are highly susceptible, while the more spreading cultivars 'A4', 'A16' and 'A268' show tolerance. Incidence is higher (p<0.05) in soils of high permeability and good drainage. No soil chemical anomaly has been found. Fine root dry weight of AVG trees (0-15 cm depth) was found lower (p<0.05) than non-AVG. Next generation sequencing has led to the discovery of a new Bacillus sp. and a bipartite Geminivirus, which may have a role in the disease. Trunk cinctures will increase (p<0.05) yield of moderately affected trees. Further research is needed to clarify whether a pathogen is the cause, the role of soil moisture in AVG, and develop a varietal solution.

Caso dermatológico

O nevo do tecido conjuntivo (NTC) é um hamartoma que pode estar associada a várias síndromes, como esclerose tube- rosa, síndrome de Buschke-Ollendorf ou síndrome de Proteus. Casos familiares de NTC têm sido relacionados com maior risco de patologia cardíaca. A apresentação clínica típica caracteriza-se pelo aparecimento de múltiplas placas cor de pele ou amareladas, confluentes no tronco e/ou nos membros, assintomáticas. São geralmente identificados na infância, sem predileção de género. O diagnóstico é confirmado por biopsia cutânea. Estudos adicionais podem ser necessários, de acordo com a presença de sinais ou sintomas sugestivos de uma doença subjacente.

Childhood Non-Langerhans Cell Histiocytosis – An Atypical Case

Introduction: Histiocytoses correspond to a heterogeneous group of disorders characterized by the proliferation andinfiltration of histiocytes in tissues. For years, many of the histiocytoses where known by numerous names, reflecting the lack of understanding regarding their origin. Case report: A previously healthy, 4-month-old infant presented a cutaneous lesion of progressive growth on his nose since 1 month ago. The mother has a diagnosis of Sjögren syndrome. On examination, there was a firm well-defined erythematous plaque with 30 mm of diameter and raised edges, on the bridge of the nose. At the left cheek, left thoracic region and right arm there were also small erythematous papules with 5 days of evolution. The analytical study showed elevated antinuclear antibodies and anti-SS-A. Histopathological examination confirmed the diagnosis of non-Langerhans cells histiocytosis. Progressively, more annular erythematous papules and plaques appeared scattered over the face, trunk and limbs with spontaneous resolution of the first lesion on the nose. About 2 months after the initial evaluation, all lesions had regressed spontaneously, with normalization of analytical study at one year-old. Conclusion: Many authors believe that the different subtypes of histiocytosis represent only different stages of the same disease. Immunophenotyping of histiocytosis does not always identify the subtype involved, making the occurrence of atypical cases frequent.

Conflictos de interés, riesgo y presiones que enfrenta a diario el periodista en La Troncal y sus sectores aledaños

El presente trabajo Riesgos y presiones del Periodista en La Troncales de trascendental importancia en el sentido que en nuestra ciudad, no existe un periodismo de vanguardia. El periodista en La Troncal, tiene un campo de acción que está empezando, está todo por hacerse; sin embargo, no deja de ser menos notorio los riesgos y presiones. Por lo tanto, no deja de ser peligrosa esta actividad para quien la ejerce. Una muestra del riesgo latente, constituye los casos que presentamos aquí en esta tesina. Así por ejemplo, el hecho de Byron Baldeón, fue un suceso que causó conmoción a nivel internacional por la crueldad con la que se actuó. Este asesinato sigue todavía en investigación, pues hasta la vez no se ha llegado a encontrar a los culpables. Así mismo, el caso de Carlos Bejarano Ramos que pasó el susto de su vida y quien estuvo a punto de morir con toda su familia se salvaron por un milagro, la bomba que fue lanzada a su morada no estalló. En conclusión, este tema que presentamos en la tesina es interesante porque el periodista en este sector se desempeña en un ambiente de mucho riesgo y lo que es peor sin apoyo de su patrono y de ninguna asociación, pues laboran algunos hasta sin seguro social lo cual hace más dramática la situación en que se hallan la mayoría de los aficionados y profesionales del periodismo tanto como de La Troncal y El Triunfo.

Accidents at work by excessive efforts / inappropriate movements in nurses

Nurses continuously develop various activities that expose them to excessive force and inappropriate movements. Characterize the accidents reported by overexertion and inappropriate movements in Portuguese nurses during 2009 and 2010. Retrospective cross-sectional study, covering the period from January 1, 2009 to December 31, 2010. Were defined as inclusion criteria, be nurse and having notified by excessive straining and improper motion accident. The information was obtained by reference to the computer record of accidents at work General Administration of Health Services, relating to 672 nurses. There were 672 notifications of accidents by overexertion/ inappropriate moves in Portuguese nurses. The higher prevalence of these accidents was in nurses with over 10 years of service 277 (41.2%), 565 were female (42.6%) in the age group 25-29 (29.9%) and practice time for 555 shifts (82.6%). At admission there were 387 (57.3%) within 3 hours of work 330 (49.1%) and the third day after weekly rest 216 (32.1%). The Mobilization of patients was the most frequent cause of this accident 430 (64.0%). The main effects were the sprains and strains 321 (47.8%), mainly the trunk reached 367 (54.7%) and absenteeism caused 373 (55.5%). On average 17.7 days missed a total of 12.054 days. There was a high prevalence of accidents during the mobilization of prayer on patients so importante to invest in the implementation of mechanical equipment for the mobilization and transport of patients.

Primary squamous cell carcinoma of the stomach presenting as a huge retroperitoneal tumor: a case report

A man complained of upper abdominal pain and early satiety for one month. An upper gastrointestinal endoscopy showed nothing special. A CT scan of the abdomen was performed, which demonstrated a huge heterogeneous retroperitoneal mass close to the dorsal wall of the stomach and surrounding the abdominal aortic and celiac trunk. The resected specimen suggested that an irregular tumor invaded the dorsal wall of the stomach. Postoperative histological examination confirmed that it was a gastric squamous cell carcinoma.

Evolution of factors affecting mechanical olive harvesting

Harvest efficiency is defined as the percentage of fruits harvested by total production. The percentage of fruits harvested is less than 100% when working with trunk shakers to detach olives. It is important to increase the percentage of fruits harvested in order to increase farmer’s income. This objective can be achieved knowing the evolution of the main factors affecting fruit detachment. Fruit removal force (FRF), fruit weight (P) and the ratio between them are important for harvest efficiency. Field trials took place for two years (2013-2014) in Vilariça Valley, northeast Portugal in an olive orchard with ‘Cobrançosa Transmontana’ cultivar. It was adopted a mechanical harvesting system based on a trunk shaker to detach fruits, and an inverted umbrella to collect fruits. Elementary operation times were measured in seconds to evaluate work rates. FRF and P were measured in the ripening period, to evaluate their evolution. In this paper are presented the preliminary results of the ratio FRF (fruit removal force)/fruit weight evolution during the ripening period (P) and the results of the equipment work rate (trees h-1). The ratio FRF/P has predominantly descendant values in the weeks before harvest, from 140 to 80 as a result of a FRF downward variation from 4.9 to 2.94 N and an upward variation of P from 0.0294 to 0.0637 N. The FRF/P ratio stabilizes the decline in the last week of November just before harvesting, registering in some cases a slight increase in consequence of FRF increase higher than P increase (contrary to the tendency of previous weeks). Equipment work rate showed values between 40 and 57 trees h-1, confirming previous results.

Biomechanical and morphological adaptations in women during pregnancy and the postpartum period in walking

A gravidez é uma fase especial da vida, com diversas alterações nos sistemas hormonais, anatómicos, e na composição corporal da mulher. No entanto, não é claro que alterações biomecânicas tridimensionais ocorrerem. Através do acompanhamento da mulher na gravidez e pós-parto, os objetivos da presente tese foram: 1) determinar os parâmetros temporais e espaciais do ciclo da marcha; 2) descrever a cinemática angular do membro inferior; 3) calcular os momentos e potências articulares do tornozelo, joelho e coxofemoral, utilizando o cálculo por dinâmica inversa; 4) descrever as magnitudes dos picos dos momentos e potências articulares dos membros inferiores; 5) identificar possíveis diferenças entre as fases de recolha relativamente aos parâmetros biomecânicos; 6) descrever longitudinalmente a composição corporal as alterações morfológicas; 7) analisar a influência das alterações antropométricas na cinética articular. Os resultados mostram que as mulheres mantêm os parâmetros temporais e espaciais da marcha. A cinemática angular do membro inferior tem o mesmo padrão, no entanto, a magnitude de alguns picos, especialmente na bacia e coxofemoral durante a fase terminal do apoio, pré-balanço e de balanço, apresentam alterações significativas. A coxofemoral é a articulação com mais alterações na cinética articular, com um aumento da carga interna associada aos momentos articulares da coxofemoral no plano transversal. No entanto, diversos momentos e potências articulares revelam uma diminuição significativa para o final da gravidez e/ou um aumento entre alguns trimestres da gravidez e o pós-parto. Como esperado, a maioria das variáveis associadas à composição corporal e às dimensões corporais tem um aumento significativo durante a gravidez e uma diminuição no pós-parto. Os modelos desenvolvidos para prever a carga interna aplicada ao membro inferior da grávida através de variáveis antropométricas, incluem quatro modelos com variáveis associadas à quantidade de gordura, quatro modelos com variáveis associadas à massa corporal global, três modelos que incluem a massa livre de gordura, e um modelo que inclui a forma do tronco. Os altos valores do R2 ajustado, mostram que as alterações na composição corporal e morfologia, determinam em grande parte a cinética articular da mulher nesta fase particular da vida.
