Vascular access thrombosis and interventions in patients missing hemodialysis sessions.

BACKGROUND: Vascular access (VA) failure is a major complication in patients with end-stage renal disease (ESRD) receiving hemodialysis (HD). Thrombosis is the most common cause of VA dysfunction, but the risk factors for VA thrombosis are not well established. While the practice of missing HD sessions (HDs) is associated with increased morbidity and mortality, its impact on VA outcomes is unknown. We evaluated the impact of missing HDs on thrombosis and intervention rates in arteriovenous (AV) accesses. METHODS: Retrospective review of prevalent HD patients using AV access was done in 2 outpatient HD centers at The Ohio State University over a one-year period. RESULTS: A total of 142 patients underwent a total of 15,692 HDs, missing 1,602 HDs. Of the 78 patients who met the inclusion criteria, 50 patients missed at least 1 HD. Those with AVF demonstrated no significant association between missing HDs and VA thrombosis. Also, the incidence rate (IR) of intervention was not significantly different for those missing and not missing HDs. However, in the AVG group, those missing HDs were more likely to experience VA thrombosis (OR 9.48, p ≈ 0.041) and had a higher IR of intervention. CONCLUSION: The practice of missing HDs was prevalent. Those missing dialysis sessions with AVG were more likely to experience VA thrombosis and needed more interventions to maintain VA patency. Our study reveals a differential impact of missing HDs on thrombosis in AVG and AVF, depicting a need to explore mechanistic explanations that may eventually help develop specific preventive strategies.

Treatment delay in oral and oropharyngeal cancer in our population: the role of socio-economic factors and health-seeking behaviour.

The objective is to assess the role of socio-economic factors and health-seeking behavior in treatment delay in oral and oropharyngeal cancer in our population. This article adapts-design: prospective study and setting: tertiary care centre. We studied 153 patients with oral and oropharyngeal squamous cell carcinoma who were managed in the department of otolaryngology and head and neck surgery between January 2006 and December 2007. There were 127 male patients (83%) and 26 females (17%) with ages ranging from 22 years to 70 years. Fifty-nine patients (39%) presented to us with early stage disease (i.e. stage I and II), whereas, 94 patients (61%) presented with late stage disease (i.e. stage III and IV). Of the 59 patients presenting with early stage disease, 20 were illiterate and 39 literate with 28 patients (47%) belonging to low socio-economic status and 32 patients (54%) having an access to primary health centre (PHC). Of the 94 patients presenting with late stage disease, 53 were illiterate and 41 literate with 58 patients (62%) belonging to low socio-economic status and 38 patients (40%) having an access to primary health centre. Literacy, socio-economic status, access to primary health centre and health-seeking behavior of our population has a significant association with the stage of presentation of patients with oral and oropharyngeal cancer.

Deafness: burden, prevention and control in India.

The high burden of deafness globally and in India is largely preventable and avoidable. According to the 2005 estimates of WHO, 278 million people have disabling hearing impairment. The prevalence of deafness in Southeast Asia ranges from 4.6% to 8.8%. In India, 63 million people (6.3%) suffer from significant auditory loss. Nationwide disability surveys have estimated hearing loss to be the second most common cause of disability. A lack of skilled manpower and human resources make this problem a huge challenge. The Government of India has launched the National Programme for Prevention and Control of Deafness. This article highlights the major components of the programme with a focus on manpower development and ear service provision including rehabilitation. Since the programme is also being implemented at the primary healthcare level, it envisages a reduction in the burden of deafness and prevention of future hearing loss in India.

Role of socioeconomic factors in deep neck abscess: A prospective study of 120 patients.

OBJECTIVE: To assess the socioeconomic factors, presentation, aetiological factors, microbiology, and management of deep neck abscesses. DESIGN: Prospective study. SETTING: Tertiary health care centre. PATIENTS AND METHODS: We studied 120 patients with deep neck abscess who were managed in the department of otolaryngology between May 2004 and December 2005. RESULTS: There were 54 male patients (45%) and 66 female (55%) with ages ranging from 18 months to 60 years. Most of the patients were of low socioeconomic status and 84 (70%) were illiterate. None were aware of the predisposing factors and potential complications of deep neck abscess. Ninety-six (80%) had poor orodental hygiene with dental infections and extraction as the most common predisposing factor followed by recurrent oropharyngeal infections. The median duration of delay before the patient presented to us was 1 week, and only 6 (5%) were aware of the primary health services available in their locality. The most common site was the submandibular region. Pain, fever, and dysphagia were the most common presenting symptoms, and Staphylococcus aureus was the most common micro-organism. All patients were treated by incision and drainage, and 10 required emergency tracheostomy. All patients responded with no complications. CONCLUSION: Socioeconomic factors, particularly ignorance, illiteracy, and poverty, are important contributory factors towards the high incidence of deep neck abscess in developing countries.

A comparative evaluation of ear diseases in children of higher versus lower socioeconomic status.

This study was conducted with an aim to assess the prevalence and profile of ear diseases in children from the higher and lower socioeconomic strata of society. Two groups of schools within Delhi were selected. Group A comprised of government schools located in slum areas with an average parental income of INR (Indian National Rupees) 1050 per month and group B of elite private schools with an average family income of TNR 35,000 per month. Three thousand children between the ages of 5-12 years were screened with the help of a written proforma and ear examination. Tympanometry and audiometry were done, where required. 19.6 per cent of children of group A were found to be suffering from ear diseases compared to 2.13 per cent of group B children. The two groups were also compared for number of family members, status of hygiene and parental education.

Psychomotor performance of psychiatric inpatients under therapy: assessment by paper and pencil tests.

Fifty psychiatric inpatients included in the study were diagnosed as having substance related disorder, schozophrenia, bipolar disorder, depressive disorder or anxiety disorder based on DSM-IV and ICD-10. All the patients were on multiple drug therapy for a minimum of 7 days in the hospital. The psychomotor performance score assessed with the help of the six letter cancellation test and the digit letter substitution test was compared with a matched group of 50 normal volunteers. The significantly low scores for patients may be considered indicative of the fact that prolonged therapy would be required to attain normal psychomotor status. Thus, simple paper and pencil tests may provide valuable information in assessment of psychomotor and cognitive functions of psychiatric patients during recovery.
