Bilateral Chylothorax Secondary to Retrosternal Goitre: a Case Report and Review of the Literature

Chylothorax is characterized by an accumulation of lymphatic fluid in the pleural cavity due to damage to the thoracic duct. The aetiology can be traumatic or non-traumatic. Goitre is a rare cause of chylothorax with only eight cases previously described in the literature including only one case causing a bilateral chylothorax. This report describes a patient with bilateral chylothorax secondary to substernal goitre, which was successfully treated, and discusses this very rare case in light of the available literature.

Placental site trophoblastic tumor: a case report and review of the literature

We present a case of a gravida 1 para 1 woman, who presented with an 11- month history of amenorrhea after cesarean delivery. The patient was taking birth control pills at the time of presentation. She was observed with a slight elevation of serum β-hCG level, an enlarged heterogeneous uterus and hematometra. A biopsy was performed, and the patient was diagnosed with placental site trophoblastic tumor; the patient then underwent surgery. Placental site trophoblastic tumor is the rarest form of gestational trophoblastic disease, derived from intermediate trophoblast cells. It does not have a pathognomonic appearance; therefore, correlation with medical history, as well as results of laboratory tests and pathological analysis is mandatory. It is a relatively chemoresistant tumor, posing considerable therapeutic challenges; patients with localized disease are managed with surgery and those with metastatic disease require additional chemotherapy. Herein, we review the main features of this entity and top differential diagnosis, as the rarity of this tumor is associated with imaging and pathological pitfalls, reinforcing the need for further experience in this field.

Papillary carcinoma arising in struma ovarii versus ovarian metastasis from primary thyroid carcinoma: a case report and review of the literature

We present a case of a postmenopausal woman diagnosed with an ovarian mass containing thyroid follicles and foci of papillary thyroid carcinoma during pathological examination. This patient referred having had a metachronous thyroid malignancy 10 years before. The differential diagnosis between a thyroid malignancy arising from a struma ovarii and a metastatic ovarian tumor originating from thyroid-cancer is challenging. Struma ovarii should be considered when thyroid components are the predominant element or when thyroid malignant tissue is identified within an ovarian lesion. Thyroid carcinoma arising from a struma ovarii is reported to occur in a minority of cases. Of these, papillary carcinoma is the most frequent subtype encountered. Regarding primary thyroid carcinomas, papillary carcinomas have a lower metastatic potential when compared to follicular carcinomas, and most of the metastases occur in the cervical lymph nodes. Ovarian metastases are exceedingly rare and generally associated with widespread disease. However, they must be considered in the presence of previous history of malignant thyroid carcinoma. The authors review the main clinical, imaging and therapeutic aspects of both these entities and present the most likely diagnosis.

First-episode psychosis in a 15 year-old female with clinical presentation of anti-NMDA receptor encephalitis: a case report and review of the literature

BACKGROUND: Anti-NMDA receptor encephalitis is an autoimmune disease that was identified in 2007, and manifests in a stepwise manner with psychiatric, neurological and autonomic symptoms. The disease is caused by autoantibodies against NMDA receptors. It can have a paraneoplastic origin, mainly secondary to ovarian teratomas, but it can also be unrelated to the tumor. This disease can affect both sexes and all ages. CASE PRESENTATION: Here, we present a case of a 15 year-old female adolescent with first-episode psychosis with anti-NMDA receptor encephalitis not related to tumor, which manifested with delusion, hallucinations, panic attacks, agitation, and neurological symptoms, and later with autonomic instability. She was treated with immunotherapy and psychiatric medication resulting in improvement of her main psychiatric and neurological symptoms. CONCLUSION: Our main objective in presenting this case is to alert clinicians to this challenging and recent disease that has a clinical presentation that might resemble a functional psychiatric condition and can be underdiagnosed in the context of child and adolescent psychiatry

The effect of software engineers' personality traits on team climate and performance: a systematic literature review

Context Over the past 50 years numerous studies have investigated the possible effect that software engineers' personalities may have upon their individual tasks and teamwork. These have led to an improved understanding of that relationship; however, the analysis of personality traits and their impact on the software development process is still an area under investigation and debate. Further, other than personality traits, "team climate" is also another factor that has also been investigated given its relationship with software teams' performance. Objective The aim of this paper is to investigate how software professionals' personality is associated with team climate and team performance. Method In this paper we detail a Systematic Literature Review (SLR) of the effect of software engineers' personality traits and team climate on software team performance. Results Our main findings include 35 primary studies that have addressed the relationship between personality and team performance without considering team climate. The findings showed that team climate comprises a wide range of factors that fall within the fields of management and behavioral sciences. Most of the studies used undergraduate students as subjects and as surrogates of software professionals. Conclusions The findings from this SLR would be beneficial for understanding the personality assessment of software development team members by revealing the traits of personality taxonomy, along with the measurement of the software development team working environment. These measurements would be useful in examining the success and failure possibilities of software projects in development processes. General terms Human factors, performance.

Understanding and development of supply chain agility and flexibility: a structured literature review

This paper provides a review of the literature while contributing to academic understanding of the concepts of agility and flexibility within the supply chain. The research identified 83 peer-reviewed articles through a structured review technique, which is based on a three-stage refinement process. Data reduction procedures using codification, sentence strings and a review of keywords, title, abstract and conclusion were used in the search. The papers identified focused on organizational and supply chain agility and flexibility. The acknowledged gaps in understanding and development of agility and flexibility in supply chains were identified and categorized in terms of conceptual, contextual and methodological gaps. Subsequent to the gap analysis, this paper argues that effective relationship integration with key partners is a fundamental mechanism for mitigating the problem of control dissipation, which has hindered academic understanding with respect to development and application of agile and flexible capabilities in supply chains. The findings in this paper will help academics to gain a better understanding and to develop the concepts of supply chain agility and flexibility. In addition, the findings indicate that supply chain stakeholders need to address the issue of relationship integration when undertaking, or participating in agility and flexibility development programmes, so as to maximize supply chain performance. The paper concludes by highlighting implications for managers and researchers, and proposes a number of areas for future investigation.

Clinical communication and adverse health events: literature review

Abstract Health institutions have an increased risk of occurrence of errors due to their diversity, specificity and volume of services, representing a great concern for health professionals whose main function is to protect the health and lives of their patients. We intend to identify a body of evidence, that shows what the most common adverse events are and what adverse events potentially arise from clinical miscommunications. An integrative literature review using the keywords "Adverse Events", "Patient Safety", "Communication". An inquiry was made on databases PubMed, Web of Science, Scielo and CINAHL, in articles published between January 2010 and March 2016, available in Portuguese and English. Of the 216 articles that emerged were selected eight articles that answered the research questions: what are the most common adverse events that have their origin in communication errors? Analyzing the selected studies, it appears that the most common adverse events arise in the context of obstetrics and pediatrics, in surgical contexts, in the continuity of care and related medication. Patient safety should be seen as a key component of quality in health care, with good management of the risk of fundamental error for the promotion of this security. The knowledge and understanding that communication failures are one of the main factors contributing to the occurrence of errors in the context of health care, allows the subsequent development of strategies to improve this process and thus ensure safer healthcare.

Benzodiazepine use of community-based violent offenders : a preliminary investigation

Objective: To explore the relationship between benzodiazepine use and violent crime in a sample of community-based offenders. Methods: Participants were recruited via drug diversion and treatment programs in Melbourne, Australia. Data regarding benzodiazepine and other substance use, mental health, personality characteristics, and crime involvement were collected through semistructured interviews conducted in 2011. Participants (n = 82, 79.3% male) were 21–56 years old, predominantly Australian-born (89%), with 14.6% identifying as Aboriginal or Torres Strait Islanders. Eligibility criteria were having been charged with a criminal offence in the previous six months and at least monthly benzodiazepine use. Group differences between violent (n = 11) and nonviolent offenders were assessed via independent samples t-tests (two-tailed) and nonparametric tests. Results: Individuals charged with violent index offences were significantly more likely to use higher average doses of alprazolam (p = 0.040) and exhibit benzodiazepine dependence (p = 0.037) as well as report high levels of sensation seeking, prior violence, and the diagnoses of depression and personality disorder than individuals charged with nonviolent index offences. Conclusions: The findings suggest the existence of a complex dynamic between mental health and violent offending that may be influenced by benzodiazepine use, in particular alprazolam. A core implication of these preliminary findings includes attending to the interpersonal skills and adaptive coping resources of violent offenders.

Total Quality Management and Corporate Social Responsibility. Literature review. The case of Nabeiro Delta Cafés Group

The relationship between the themes of Total Quality Management (TQM) and Social Responsibility (CSR) through the concepts, approaches and models of excellence is a reality of sustainable and stable companies. Being organizations, people, act correctly and rightly do in society go through a quality management and social responsibility thereof. It is based on these two philosophies (Total Quality Management and Corporate Social Responsibility), which developed this literature review work, essentially based on a relational analysis in two papers, namely: "TQM and CSR Nexus" by Ghobadian et al. (2007) and "The Corporate Social Responsibility Audit Within the Quality Management Framework," de Kok et al. (2001) and applied to an organizational situation in concrete: the Nabeiro Delta Cafés Group - SGPS, SA.

When the object speaks, a postcolonial encounter : anthropological, representations and Aboriginal's women's self-presentations

As an Aboriginal woman currently reviewing feminist literature in Australia, I have found that representations of Aboriginal women's gender have been generated predominantly by women anthropologists. Australian feminists utilise this literature in their writing and teaching and accept its truths without question; the most often quoted ethnographic text is Diane Bell's Daughters of the Dreaming (1983a).1 Feminists' lack of critical engagement with this literature implies that they are content to accept women anthropologists' representations because Aboriginal women are not central to their constructions of feminism.2 Instead the Aboriginal woman is positioned on the margins, a symbol of difference; a reminder that it is feminists who are the bearers of true womanhood.
