After an extensive review of the literature, regarding zinc.oxide/eugenol impression pastes, we selected 20 of the most representatives as our references. Trough personal information of several of the investigators it was discovered that dimensional changes of theese materials is one of the most difficult properties to be measured. A new method was developed to measure dimensional changes ot 4 (four) of the most widely used zinc.oxide/eugenol impression materials in Brazil. The results, presented through several graphs and tables showed that dimensional changes varied from 0,003%, values which may probably be considered negligible from a clinical point of view. We noticed, however, high values for standard deviation and variance which indicate the high variability within the experiments. Those values were not found when we used the same method with mercaptan and silicone impression materials, in which the measurement of dimensional changes was highly reproducible. One hypothesis (which we intend to investigate in a later research) is that, during storage, a sedimentation could occur, of the components of greater density! Consequently ther might result a change in composition, independent of the method used to establishe the proportion of the two pastes, be it by wheight or measurement of lenght, which could be the cause of variability of the composition of each mixture!

Endocrine diseases have a considerable impact on public health from an epidemiological point of view and because they may cause long-term disability, alteration of the quality-of-life of the affected patients, and are the fifth leading cause of death. In this extensive review of the literature, we have evaluated the prevalence of the different disorders of endocrine interest in the world and Italy, highlighting their epidemiological, clinical, and economic impact.

The review of the literature on anesthesia in pregnant women with subarachnoid hemorrhage is presented. Physiological changes of pregnancy should by undoubtedly taken into consideration while performing anesthesia and surgery because of the comorbidities. Particularly, the oxygen intake is higher in pregnant. Adequate systolic pressure is also a very important parameter maintaining the intrauterine blood flow and fetus perfusion during the whole term of pregnancy. Medications used in pregnant women can also influence the fetus. From the clinical point of view, the selection of anesthetics and other medications allowed for use in pregnant women should be limited to medications that are proven to be safe. Pharmacological effects of the medications, used for anesthesia and treatment of pregnant women with subarachnoid hemorrhage are covered in the review, including their influence on fetus. Surgical treatment options for pregnant women at different pregnancy terms with different conditions requiring neurosurgery are surveyed. Post-surgical rehabilitation of pregnant women with subarachnoid hemorrhage is reviewed. In each particular clinical case an individual anesthesia plan should be created considering the pregnancy term and features of the disease.

Newborn skin disorders are quite common and happen to occur during the neonatal period. Most of the birthmarks are transient; however, worried parents often seek medical advice from their child’s physician regarding skin lesions. Thus, it is important to differentiate the skin lesions from pathologic ones to avoid unnecessary diagnostic or therapeutic procedures. This is the first published study in Lao neonates that carried out the data from 4 central hospitals in Vientiane Capital, Lao PDR from September 2019 to February 2020. Among 500 neonates, Sebaceous gland hyperplasia (53%), Mongolian patches (46.6%), and Erythema toxicum neonatorum (30%) were the 3 most common cutaneous conditions found in the Lao newborns. From a clinical point of view, these findings are often a source of parental anxiety and medical concern for inexperienced clinicians.

BackgroundThe NHS is a fascinating health care system and is enjoying a lot of support from all layers of British society. However, it is clear that the system has excellent features but also areas that can be improved.Story of selfA number of years as a chief executive in one of London’s largest hospital has brought me a wealth of impressions, experiences, and understanding about working in the NHS. Contrasting those to my previous experience as chief executive in Amsterdam (The Netherlands) provides an interesting insight.ObservationsVery strong features of the NHS are the high level of health care professionals, the focus on quality and safety, and involvement of patients and the public. However, the NHS can significantly improve by addressing the lack of clinical professionals in the lead, curtailing ever increasing bureaucracy, and reducing its peculiar preference for outsourcing even the most crucial activities to private parties. The frequent inability to swiftly and successfully complete goal-directed negotiations as well as the large but from a clinical point of view irrelevant private sector are areas of sustained bewilderment. Lastly, the drive for innovation and transformation as well as the level of biomedical research in the NHS and supported by the British universities is fascinating and outstanding.

We assessed the mental and neurological health (MNH) situation of Ecuador in 2006–8, using the Mental and Neurological Health Country Profile (MNHCP) (Gulbinat et al, 2004; Jenkins, 2004; Jenkins et al, 2004), an instrument which helps to develop evidence-based MNH policy and services (Townsend et al, 2004). An extensive review of the literature was undertaken and consultations and consensus meetings (Schilder et al, 2004) were conducted with key mental and neurological health stakeholders, including consumers, carers and clinicians from the government and non- government sectors.

In this study, the risk assessment levels of athletes in different branches were examined in terms of various variables. Descriptive scanning model was used in the study. In the research, the survey was completed with a sample method of 105 people. The questionnaire was used as a data collection tool in the research. The questionnaire consists of questions about personal information and the Risk Assessment scale for athletes and coaches. Data analysis was performed in SPSS 21 package program. Descriptive statistics such as frequency, percent, and mean, standard deviation, minimum and maximum were used in data analysis. Data analysis was performed in SPSS 21 package program. Descriptive statistics such as frequency, percent, and mean, standard deviation, minimum and maximum were used in data analysis. As a result of the research, it was determined that the risk assessment perceptions of athletes according to their age, branches, educational status and income status did not differ.

(1) Background: The Antiphospholipid Syndrome (APS) is a systemic autoimmune disorder characterized by arterial and/or venous thrombosis, pregnancy morbidity and raised titers of antiphospholipid antibodies. Cerebral vein thrombosis (CVT) is a rare form of cerebrovascular accident and an uncommon APS manifestation; the information in the literature about this feature consists of case reports and small case series. Our purpose is to describe the particular characteristics of CVT when occurs as part of the APS and compare our series with the patients published in the literature. (2) Methods: We conducted a retrospective observational study collecting data from medical records in three referral centers for APS and CVT, and a systematic review of the literature for CVT cases in APS patients. (3) Results: Twenty-seven APS patients with CVT were identified in our medical records, the majority of them diagnosed as primary APS and with the CVT being the first manifestation of the disease; additional risk factors for thrombosis were identified. The review of the literature yielded 86 cases, with similar characteristics as those of our retrospective series. (4) Conclusions: To our knowledge, our study is the largest CVT series in APS patients published to date, providing a unique point of view in this rare thrombotic manifestation.
