Ultrasonography in the detection of cervical incompetency   总被引:2,自引:0,他引:2  
In 80 pregnancies with clinical and ultrasonic signs of cervical incompetency, the length of the cervix and the thickness of the anterior wall of a lower uterine segment have been evaluated ultrasonically. We have also measured the width of the endocervical canal and studied the prolapse of fetal membranes (with fetal parts) into the endocervical canal. We evaluated these same parameters in 80 healthy pregnancies. The length of the cervix, the thickness of the anterior wall of a lower uterine segment, and the width of the endocervical canal were followed longitudinally in the patients from the 10th to the 36th gestation week. No statistically significant differences between age groups were found. In four age groups at risk for cervical incompetency, cervical lengths and wall thickness were significantly different (p less than 0.001) from those in comparable controls. Forty-five percent of the patients in the at-risk group, with cervical cerclage, delivered at 37.3 (range: 32 to 41) weeks and 6.25% of pregnancies ended in abortion when the amniotic membrane herniated into the cervical canal, with or without some part of the fetus.  相似文献

Aim

To assess the quality of outpatient pediatric care provided by township and village doctors, prevalence of common childhood diseases, care-seeking behavior, and coverage of key interventions in Zhao County in China.

Methods

We conducted two cross-sectional surveys: 1) maternal, newborn, and child health household survey including1601 caregivers of children younger than two years; 2) health facility survey on case management of 348 sick children younger than five years by local health workers and assessment of the availability of drugs and supplies in health facility.

Results

Our household survey showed that the prevalence of fever, cough, and diarrhea was 16.8%, 9.2%, and 15.6% respectively. Caregivers of children with fever, cough, and diarrhea sought care primarily in village clinics and township hospitals. Only 41.2% of children with suspected pneumonia received antibiotics, and very few children with diarrhea received oral rehydration solutions (1.2%) and zinc (4.4%). Our facility survey indicated that very few sick children were fully assessed, and only 43.8% were correctly classified by health workers when compared with the gold standard. Use of antibiotics for sick children was high and not according to guidelines.

Conclusion

We showed poor quality of services for outpatient sick children in Zhao County. Since Integrated Management of Childhood Illness strategy has shown positive effects on child health in some areas of China, it is advisable to implement it in other areas as well.Globally the number of deaths of children younger than five years decreased from 9.6 million to 7.6 million between 2000 and 2010, despite increases in the number of live births (1-3). During the past 20 years China made great achievements concerning child survival. Between 1990 and 2006, under-five mortality rate decreased from 64.6 to 20.6 per 1000 live births, and Millennium Development Goal 4 (MDG4) was achieved nine years ahead of the target set for 2015 (4-6). In 2011, under-five mortality rate was further reduced to 15.6 per 1000 live births (7). While this progress is remarkable, there remains the challenge of urban-rural mortality rate differences. Under-five mortality rate in rural areas was 2.7 times higher than in urban areas, 19.1 and 7.1 per 1000 live births, respectively (7).Under-five mortality decrease was achieved by focusing on social development and sustained economic growth and investments in health system, including expansion of health intervention coverage (8-10). However, these were much lower in rural areas. In 2010, rural residents’ net income per capita was 5919 Yuan, which was less than one third of urban residents’ income (19 109 Yuan) (11), and the health expenditure per capita in urban areas was 3.5 times lower than in rural areas, 2316 Yuan vs 666 Yuan (7). In 2009, the number of health professionals per 1000 population was 6.03 in urban and 2.46 in rural areas, respectively (12). These factors reduce overall rural health care quality as well as the quality of pediatric care, which in rural China is often less than desirable (13-15).To improve child survival, in the mid-1990s the World Health Organization (WHO) and United Nation’s Children Funds (UNICEF) jointly developed the Integrated Management of Childhood Illness (IMCI) strategy (16,17). The IMCI strategy has reduced the number of deaths due to diarrhea, pneumonia, malaria, measles, and malnutrition, which was estimated to 70% of all global deaths of children younger than 5 years at that time (18). IMCI has already been introduced into more than 100 countries (WHO 2005). In China it was introduced in 1998 and since 2003 has been expanded to 46 counties in 11 provinces, considerably improving health workers’ skills (19,20). Although IMCI has been in force in China for more than 10 years, training coverage remains very low for township and village doctors (21).In 2010, the Ministry of Health of China launched a research project aiming to explore the use of appropriate medical techniques in rural areas, and IMCI was selected as a key component of the project. We carried out a household survey and a health facility survey in Zhao County, Hebei Province before IMCI implementation. The household survey aimed to assess the prevalence of common childhood diseases, care-seeking behaviors, and population coverage of key interventions, and the health facility survey aimed to assess the quality of outpatient pediatric care by township and village doctors.  相似文献

Introduction

Lumbar fusion has been found to be a clinically effective procedure in adult patients. The lateral transpsoas approach allows for direct visualization of the intervertebral space, significant support of the vertebral anterior column, while avoiding the complications associated with the posterior procedures. The aim of this study is to determine the fusion rate of inter body fusion using computed tomography in patients treated by extreme lateral intersomatic fusion (XLIF) technique.

Materials and methods

All patients intervened by XLIF procedure between 2009 and 2013 by a single operating team at a single institution were recruited for this study. A clinical evaluation and a CT scan of the involved spinal segments were then performed with at least 1-year follow-up following the standard clinical practice in the center.

Results

A total of 77 patients met inclusion criteria, of which 53 were available for review with a mean follow-up of 34.5 (12–62) months. A total of 68 (87.1 %) of the 78 operated levels were considered as completely fused, 8 (10.2 %) were considered as stable, probably fused, and 2 (2.6 %) of the operated levels were diagnosed as pseudarthrosis. When stratified by type of graft material complete fusion was obtained in 75 % of patients in which autograft was used to fill the cages, compared to 89 % of patients in which calcium triphosphate was used, and 83 % of patients in which Attrax? was used.

Discussion

Reports of XLIF fusion rate in the literature vary from 85 to 93 % at 1-year follow-up. Fusion rate in our series corroborates data from previous publications. The results of this series confirm that anterior inter body fusion by means of XLIF approach is a technique that achieves high fusion rate and satisfactory clinical outcomes.

Purpose

The aim of this study was to investigate through a questionnaire the knowledge, attitudes and possible differences in the use of flexible RPDPs among dentists in Greece and Croatia.

Material and Methods

A questionnaire of 16 questions was originally created in English, translated into Greek and Croatian language following a two way translation and tested for apprehension, precision, clarity and homogeneity by a number of native English speaking Greek and Croatian dentists. Following the necessary corrections, the questionnaires replicated in two online surveys and their addresses with an informed consent were sent by emails to nearly 4000 dentists in each country to participate. Collected data were analyzed by chi-square tests at a= .05 level of significance.

Results

378 dentists from Greece and 304 from Croatia participated in the study. 137(36.2%) dentists from Greece and 56(18.4%) from Croatia provided flexible RPDPs to their patients. Statistical analysis for all providers indicated no significant difference between genders (P>.05), significant differences between age groups (P<.01), years of practice (P<.05), specialization (P <.001), and instruction on flexible prostheses (P <.001). The analysis between the two countries showed differences for gender and age groups (P<.01) but no differences between experienced, specialized or instructed groups (P >.05).

Conclusion

The survey indicated differences between the two countries in the percentages of dentists using, selecting and providing RPDPs for their patients. Practitioners’ age, years in practice and instruction were associated with the provision of the prostheses, while comfort, esthetics and cost were the reasons for deciding to use the flexible RPDPs.

Conclusion

Although dentists are not educated in their schools about flexible RPDPs, almost a third of them offer this treatment to their patients. Long term success of these devices depends on clinical education, more experience and definitely more research.  相似文献

Heart failure (HF) is a complex clinical syndrome characterized by the activation of at least several neurohumoral pathways that have a common role in maintaining cardiac output and adequate perfusion pressure of target organs and tissues. The sympathetic nervous system (SNS) is upregulated in HF as evident in dysfunctional baroreceptor and chemoreceptor reflexes, circulating and neuronal catecholamine spillover, attenuated parasympathetic response, and augmented sympathetic outflow to the heart, kidneys and skeletal muscles. When these sympathoexcitatory effects on the cardiovascular system are sustained chronically they initiate the vicious circle of HF progression and become associated with cardiomyocyte apoptosis, maladaptive ventricular and vascular remodeling, arrhythmogenesis, and poor prognosis in patients with HF. These detrimental effects of SNS activity on outcomes in HF warrant adequate diagnostic and treatment modalities. Therefore, this review summarizes basic physiological concepts about the interaction of SNS with the cardiovascular system and highlights key pathophysiological mechanisms of SNS derangement in HF. Finally, special emphasis in this review is placed on the integrative and up-to-date overview of diagnostic modalities such as SNS imaging methods and novel laboratory biomarkers that could aid in the assessment of the degree of SNS activation and provide reliable prognostic information among patients with HF.  相似文献
