Objective: Healthcare services using mobile-phone based telemedicine provide simple technology that does not require sophisticated equipment. This study assessed community health workers’ knowledge, attitude, and practice (i.e., their readiness) at the village level for uptake of mobile-phone based telemedicine.Materials and Methods: This cross-sectional study was conducted among 80 community health workers, including Auxiliary Nurse Midwives, Multipurpose Health Workers and Accredited Social Health Activists working in a rural health block of India. A pre-tested, semi-structured, interviewer-assisted, self-administered questionnaire was used to assess their mobile-phone based telemedicine readiness.Results: Sixty (75.0%) health workers owned mobile phones. The median readiness score for mobile-phone based telemedicine was 109.0. The Accredited Social Health Activists showed a better attitude toward mobile-phone based telemedicine than others. There was a significant moderate positive correlation (r=0.67) between knowledge and practice domains. Community health workers who had smartphones showed a significantly better attitude than those who did not.Conclusion: Training programs on telemedicine service delivery, focused on Auxiliary Nurse Midwives/ Multipurpose Health Workers, can improve their attitudes towards telemedicine. A better attitude of the Accredited Social Health Activists must be leveraged to initiate mobile-phone based telemedicine services on a pilot basis initially and later scaled up in other settings.  相似文献

Blunt traumatic diaphragmatic injuries in children   总被引:3,自引:0,他引:3  
Diaphragmatic injuries following blunt trauma are rare. From January 1988 to February 2002 eight children were treated at the Children's Hospital at Westmead for diaphragmatic injury. Male to female ration was 5:3. Motor vehicle crashes were the most common cause. The injury was left-sided in four, right sided in three and central in one. Initial plain radiograph and computerised tomography detected the injury in 50% of cases. Laparotomy, contrast study and autopsy identified the rupture in one each. Associated injuries were present in all cases. Seven children had laparotomy and repair of the diaphragmatic rupture. The commonest site of rupture was posterolateral (37.5%). Diagnosis was delayed in two cases. There were two deaths (25% mortality) in the series, both due to associated injuries. Although rare, diaphragmatic rupture must be considered in any child with thoracoabdominal injury. Diagnosis may be difficult and require extensive investigation. Mortality usually results from associated injuries.  相似文献

Traumatic spinal epidural hematoma is rare in children. The presentation could be nonspecific, leading to a delay in diagnosis. We present an infant who sustained an epidural hematoma after a "trivial" injury. The delay in diagnosis led to minor neurological deficit at 6-week follow-up. Irritability and torticollis after a neck trauma in an afebrile child should alert to the possibility of spinal cord compression. Early imaging and early decompression will minimize morbidity.  相似文献

Desmoid tumours are generally very rare but occur about 100 times more frequently in the colorectal cancer predisposition syndrome familial adenomatous polyposis (MIM 175100), being represented in about 10% of patients. In addition to desmoid disease occurring in familial adenomatous polyposis (FAP) there exist familial infiltrative fibromatosis (MIM 135290) kindreds where there is no evidence of FAP. Previously we have described a kindred with familial infiltrative fibromatosis (FIF) in which desmoid tumours were associated with nonpolyposis colorectal cancer. FAP is caused by mutations in the APC gene and various genotype-phenotype relationships have been defined including reports that colorectal polyposis is less severe with mutations 5' to codon 157 and that the risk of desmoid tumours is high in FAP patients with APC gene mutations between codons 1444 and 1598. There is relatively little information on the phenotype of APC gene mutations 3' to codon 1598; however, one large family has been reported with a mutation at codon 1987 which presents with a highly variable phenotype which includes desmoid disease. We screened our original FIF kindred and three further families with a similar phenotype for mutations in the APC gene. A 4 bp frameshift deletion in codon 1962 was identified in the original FIF kindred and two further apparently unrelated families. Haplotype analysis suggests a common origin for the APC mutation in all three families. Affected individuals had no evidence of congenital hypertrophy of the retinal pigment epithelium. Colorectal polyposis was variable, and most affected patients had either none or a few late onset polyps. These findings demonstrate (i) that FAP and FIF are allelic, and (ii) that APC gene mutations which truncate the APC protein distal to the beta-catenin binding domain are associated with desmoid tumours, absent CHRPE and variable but attenuated polyposis expression.   相似文献
