预防接种对学校卫生安全的影响

目的：：了解学校某地区小学生的预防接种情况,探讨预防接种对学校传染病控制及学校卫生安全的影响。方法：回顾性分析2010年5月~2012年5月某地区小学新生的预防接种情况。结果：本次共调查小学新生3742人,其中有接种记录的3145人,占84.0%。调查发现,各种疫苗全程免疫接种率的情况为：城市小学>农村小学>城市流动新生;传染病总发生率情况为：城市流动新生>农村小学>城市小学。说明预防接种可以有效降低传染病的发生率。结论：预防接种是预防和控制学校传染病的重要措施,也是保证学校卫生安全的关键。因此,学校要加强计划免疫管理和预防接种证等工作,以提高在校生的预防接种率,降低传染病突发事件的发生率。

The prevention of osteoporosis and sarcopenia in older adults

Osteoporosis and sarcopenia are common in older adults. Osteoporosis is a systemic skeletal disease characterized by low bone mass and microarchitectural deterioration of bone tissue, with a consequent increase in bone fragility and susceptibility to fracture. Bone fractures can result in changes in posture, pain, the need for surgical repair and functional impairment. Sarcopenia is the progressive and generalized loss of skeletal muscle mass, strength and/or physical performance. Older adults with sarcopenia experience increased risk of frailty, disability, hospitalizations, mortality, and a reduced quality of life. In this narrative review we provide guidance regarding the prevention of both osteoporosis and sarcopenia, including interventions that prevent both conditions from occurring, recommended screening and treatment to prevent progression.     

Advances in pharmacotherapy for primary biliary cirrhosis

Introduction: Primary biliary cirrhosis (PBC) is a chronic autoimmune liver disease mostly seen in middle-aged women characterized by progressive nonsuppurative destruction of small bile ducts resulting in intrahepatic cholestasis, parenchymal injury and ultimately end-stage liver disease. Despite major breakthroughs in our understanding of PBC, there remains only one FDA-approved agent for treatment: ursodeoxycholic acid (UDCA) to which one-third of patients are unresponsive.

Areas covered: Biochemical response to treatment with UDCA is associated with excellent survival rates in PBC patients. However, there is a need for alternative treatments for nonresponders. Results from human epidemiological and genetic studies as well as preclinical studies in PBC animal models have provided a strong impetus for the development of new therapeutic agents. In this review, we discuss the recent advances in translational research in PBC focusing on promising therapeutic approaches, namely immune-based targeted therapies and agents targeting the synthesis and circulation of bile acids.

Expert opinion: We are in a new era for the development of novel therapies for PBC. Data on fibrates, budesonide and obeticholic acid offer encouragement for nonresponders to UDCA.     

Self-perception of theoretical knowledges and practical skills by primary health care physicians in life-threatening emergencies according to their gender: A cross-sectional study

To assess the training received in Emergency Medicine (EM) by the Primary Health Care physicians of Asturias, as well as their perception of their own theoretical knowledge and practical skills in a series of procedures employed in life-threatening emergencies, and also to analyze the differences according to gender. The degree of preparation of Primary Health Care physicians for handling emergencies, according to the gender of the professionals, has never been studied before.Cross-sectional study of a sample of 213 Primary Health Care physicians from the Primary Health Care Service of Asturias, Spain, from among the total of 851 physicians on the staff of the Primary Health Care Service of Asturias. The survey was design ad hoc using the Body of Doctrine of Emergency Medicine proposed by the Spanish Society of Emergency Medicine, which indicates the theoretical and practical procedures that must be mastered by the Primary Health Care physicians.There are nonsignificant differences in the mean of theoretical knowledge and practical skills in many procedures or techniques studied depending on the gender.Female and male Asturian Primary Health Care physicians are generally well prepared to handle life-threatening emergencies. The degree of self-perception and acquisition of general theoretical knowledge and general practical skills for handling life-threatening emergencies is heterogeneous, and differences according to gender are not statistically significant.     

Primary inguinal subcutaneous endometriosis accompanied with an inguinal hernia: A case report

Rationale:We report a case with inguinal subcutaneous endometriosis without typical cyclic dysmenorrhea and accompanied with a hernia sac treated with resection of the tumor and herniorrhaphy.Patient concerns:A 40-year-old woman had a painless enlarged inguinal nodule for 3 months.Diagnoses:Subcutaneous endometriosis accompanied with a hernia sac.Interventions:Ultrasonography showed a hypoechoic lesion (3.0 cm × 2.0 cm), and an inguinal subcutaneous tumor was first suspected. After surgical exploration, a cystic lesion was excised and the hernia hole was repaired by herniorrhaphy. The immunohistochemical analysis of the small endometriotic cyst-like lesion revealed calretinin (-) in epithelial cells and CD10 (+) in stromal cells, indicative of subcutaneous endometriosis accompanied with a hernia sac.Outcomes:The patient was followed up for 1 year and without recurrence.Lessons:Cutaneous endometriosis accompanied with a hernia sac can be presented without typical endometriosis-associated symptoms such as dysmenorrhea. Inguinal endometriosis might be the differential diagnosis of inguinal painless nodules.
