Psychometric analysis of the Functional Independence Score in Haemophilia (FISH)

Joint morbidity in haemophilia has traditionally been measured using clinical and radiological scores. There have been no reliable, validated tools for the assessment of functional independence in persons with haemophilia till recently. The Functional Independence Score in Haemophilia (FISH) has been developed as a performance based assessment tool to address this need. The FISH is designed to measure the patient's independence in performing activities of daily living (grooming and eating, bathing and dressing), transfers (chair and floor), and mobility (walking, step climbing and running). On assessment of its psychometric properties in 63 patients with haemophilia (mean age 14 years), FISH was found to have good internal consistency (Cronbach's alpha of 0.85). It had moderate correlation with the World Federation of Hemophilia clinical score (r = -0.61), and a correlation with the Pettersson score of -0.38. It had good correlation with other self-rated functional scores, such as the Stanford Health Assessment Questionnaire (r = -0.75); the Western Ontario and McMaster Universities Osteoarthritis Index (r = -0.66) and the Haemophilia Activities List (HAL) (r = -0.66). It had good reliability with a pooled intra class correlation of 0.98. On assessing responsiveness following treatment of flexion deformities of the knee in 12 patients, the FISH showed significant changes in the score with a standardized responsiveness mean of -1.93. In conclusion, the FISH was found to be a reliable and valid tool with good internal consistency and responsiveness to therapy, for the assessment of functional independence in persons with haemophilia.

Functional Independence Score in Haemophilia: a new performance-based instrument to measure disability

Morbidity in haemophilia has been described predominantly in terms of musculoskeletal dysfunction and assessed by the clinical and radiological joint scores. These scores document changes in a particular joint, but do not reflect the impact of these changes on the individual in terms of his overall musculoskeletal function. Several self-assessment instruments have been used to measure musculoskeletal function but none have been specifically validated for use in haemophilia. In order to objectively assess musculoskeletal function of patients with haemophilia, we developed Functional Independence Score in Hemophilia (FISH), a performance-based instrument. FISH measures the patient's independence in performing seven activities under three categories: self-care (grooming and eating, bathing and dressing), transfers (chair and floor) and mobility (walking and step climbing). Each function is graded from 1 to 4 depending on the amount of assistance needed in performing the function. We evaluated 35 patients who were over 10 years old and had had at least three major bleeds per year. All subjects were scored for clinical (World Federation of Hemophilia, WFH score) and radiological changes (Pettersson's score). Functional independence of the patient was assessed using the Stanford Health Assessment Questionnaire (HAQ) and the FISH. Correlation of the FISH score was modest with both the WFH clinical score (r = -0.68) and the radiological score (r = -0.44). While there was good correlation between FISH and HAQ (r = -0.90), FISH had better internal consistency than HAQ (Cronbach's alpha 0.83 vs. 0.66). FISH appears to be a promising disease-specific instrument for assessing overall musculoskeletal function in haemophilia. It requires evaluation in different patient populations.

Dose and outcome of care in haemophilia - how do we define cost-effectiveness?

Severe haemophilia (factor [F]VIII/FIX activity < 0.01 IU mL(-1)) is characterized by repeated haemarthroses resulting in severe arthropathy in adulthood. In 1958, Professor Nilsson in Sweden introduced prophylactic infusions with clotting factor concentrates at regular intervals in order to maintain clotting factor levels above 0.01 IU mL(-1) and to prevent bleeding. Since then, evidence of the long-term beneficial effects of prophylactic treatment for severe haemophilia has been increasing and it has become the recommended treatment strategy for children with severe haemophilia by both the World Health Organization and the US National Hemophilia Foundation Medical and Scientific Advisory Committee. However, the implementation of this recommendation has been hampered by issues of cost and venous access. The high costs of prophylaxis have largely prevented its use in major parts of the world. The question therefore is whether the current models of replacement of clotting factor concentrates, while certainly being effective, are also optimal. Can the data on outcome at different levels of factor replacement be used to assess their cost-effectiveness?

Persistent rhinorrhoea in rural Indian children: prevalence and consequences

To determine whether persistent rhinorrhoea constitutes a significant problem requiring intervention, 17 rural day care centres (Balwadis) in Tamilnadu, India, were visited. Among 414 children in the Balwadis 92 (22 per cent) children with persistent rhinorrhoea (15 days duration or longer) were identified. Demographic and clinical data and nasopharyngeal swabs for bacterial culture were obtained from 56 such children and 91 age-matched controls from the same Balwadi. Type of housing or nutritional status did not appear to be significant risk factors. There was a significantly higher number of children aged 5-15 years in the household of cases as compared to controls (1.23 +/- 1.08 vs. 0.83 +/- 0.95, p = 0.02). Other illnesses were noted in 25 (44.6 per cent) cases and seven (7.7 per cent) controls (OR 11.5; CI, 4.13-33.4; p < 0.00001). Notably, chronic ear discharge was noted in 6 (11.7 per cent) cases but in none of the controls (p = 0.007). Streptococcus pneumoniae was isolated from nasopharyngeal swabs in 42/49 (85.7 per cent) cases and 44/80 (55 per cent) controls (p < 0.001) and H. influenzae from seven cases and five controls; S. pneumoniae was isolated in all children with chronic ear discharge and H. influenzae from one child. Serotypes of pneumococci commonly associated with otitis media, i.e., types 6, 14, 19, and 23 were isolated from 25 (51 per cent) cases and 16 (20 per cent) controls (OR 4.17; 95% CI, 1.78-9.85; p < 0.001). Persistent rhinorrhoea, presumably due to pneumococcus, is a common condition among rural Indian children and appears to be associated with chronic otitis media.

Psychological wellbeing among carers of people with spinal cord injury: a preliminary investigation from South India

STUDY DESIGN

A cross-sectional study that assessed people with spinal cord injury (SCI) and their carers who attended the 3-day health care program.

OBJECTIVES

The study examined the nature and prevalence of the factors associated with psychological morbidity among carers of people with SCI.

SETTING

A community reintegrated population of persons with SCI and their carers attended the 3-day program in the Department of Physical Medicine and Rehabilitation, Christian Medical College Hospitals, Vellore, South India.

METHODS

Thirty-eight people with SCI and their carers participated in this cross-sectional study.

RESULTS

Thirty (78.9%) carers of people with SCI were psychologically distressed. While carers were distressed, they were not significantly depressed. Educational level of carers and suicidal behavior of people with SCI were significantly associated with psychological distress.

CONCLUSION

The findings of this study suggest that health care workers should have a high index of suspicion of psychological morbidity, in carers of people with SCI. Identification of risk factors may lead to useful target interventions.

Measles vaccination before nine months

OBJECTIVE

To measure the protective effect of measles vaccine administered before 9 months of age and compare overall mortality of children vaccinated at 6-8 months and at 9-11 months.

METHOD

Non-concurrent cohort study involving all 13 134 children born between 16 January 1986 and 31st December 1991 in Kaniyambadi block near Vellore who had not left the area by six months of age. Main outcome measures were risk of disease and death among the under-five-year-olds according to age at measles immunization.

RESULTS

Unimmunized children had a higher risk of developing measles compared to the immunized (P < 0.05). There was no significant difference in risk of measles among those vaccinated prior to and after nine months of age. Unvaccinated children were at significantly higher risk of death than vaccinated children (P < 0.001). There was no difference in risk of death between infants vaccinated between 6 and 8 months and those vaccinated between 9 and 11 months. There was no difference in the risk of death between boys and girls vaccinated between 6 and 8 months with standard-titre Edmonston-Zagreb vaccine.

CONCLUSION

Administration of standard-titre Edmonston-Zagreb measles vaccine at 6-8 months is an effective and safe preventive measure for measles, especially where the age-specific attack rate for children < 9 months is high.

Glucose intolerance and dyslipidaemias in persons with paraplegia and tetraplegia in south India

Glucose intolerance and dyslipidaemias have been reported among paraplegics and tetraplegics. In this study we determined the lipid profiles and the glucose tolerance in a group of 48 persons with spinal cord lesions who had been rehabilitated in our Department of Physical Medicine and Rehabilitation. This non-randomised, descriptive study was conducted as part of the annual medical follow-up of these individuals. Hypertension was observed in only 6% of the subjects. Fasting hyperglycemia was observed in 19% and glucose intolerance in 23% of the subjects. Total cholesterol was abnormal in 2%, but 58% had low levels of high density lipoprotein (HDL). 10% of the subjects had raised low density lipoprotein (LDL) levels. The cardioprotective HDL fraction may remain very low even while the total cholesterol level is within normal limits, and unless a lipid profile estimation is done, this group of individuals who are at cardiovascular risk may remain undetected. We conclude that glucose intolerance and dyslipidaemias are common among paraplegic and tetraplegic individuals, and these metabolic derangements may contribute to increased cardiovascular morbidity.

An outbreak of food poisoning in Tamil Nadu associated with Yersinia enterocolitica

An outbreak of food poisoning in a Tamil Nadu village, affecting 25 of 48 individuals who participated in a feast, was investigated. The risk of developing illness was associated with consumption of buttermilk (relative risk 3.8). None of the food items consumed during the feast was available for analysis. Toxin-producing Y. enterocolitica (serotype 3, biotype 4) was grown from 1 of 11 stool samples from affected individuals, as well as from a water sample from the source used to dilute the buttermilk. High titres of antibody of Yersinia were detected in 2 of 12 patients but in neither of the two groups of controls. Toxin production was noted in buttermilk incubated for 6 h with Y. enterocolitica. This is the first report from India of a food poisoning outbreak associated with this organism.

Malignant secondary deposit in the iliac crest masquerading as meralgia paresthetica

Meralgia paresthetica is an entrapment neuropathy from compression of lateral femoral cutaneous nerve of the thigh as it passes under the inguinal ligament. The entrapment produces pain, paresthesia, and sensory loss over the anterolateral aspect of the thigh, without motor loss. The etiology of this condition is often obscure and the pathogenesis is thought to be an entrapment of this nerve at the inguinal ligament where it pierces the fascia to reach the skin. Rarely, retroperitoneal lymphomas or other neoplasms can mimic symptoms of meralgia paresthetica. We report a case of a 60-year-old man who presented with clinical features of meralgia paresthetica. On investigation, he was found to have a secondary malignant deposit in the iliac crest from an adenocarcinoma of the lung. This neuropathy, although often caused by a benign lesion, can at times be the presenting symptom of a malignancy.

Aspirin in chloroform as an effective adjuvant in the management of chronic neurogenic pain

OBJECTIVE

To evaluate the effectiveness of topical application of aspirin in chloroform as an adjuvant in the management of chronic neurogenic pain.

DESIGN

Intervention study, nonrandomized before-and-after trial.

SETTING

A department of physical medicine and rehabilitation in a tertiary-care university teaching hospital.

PARTICIPANTS

Fifteen adults who presented with severe, chronic neurogenic pain in whom, conventional methods of treatment were unsuccessful in alleviating the pain.

INTERVENTION

A solution of aspirin (acetyl salicylic acid) in chloroform was applied over the painful areas.

MAIN OUTCOME MEASURES

A numerical scale from 0 to 100 was used to measure the severity of pain.

RESULTS

Seventy-four percent of patients showed a good response, 13% had fair response, and in 13% there was no response.

CONCLUSION

Aspirin in chloroform solution is a simple and effective adjuvant in the management of chronic neurogenic pain.

A case-control study of maternal knowledge of malnutrition and health-care-seeking attitudes in rural South India

INTRODUCTION

In India, approximately 20 percent of children under the age of four suffer from severe malnutrition, while half of all the children suffer from undernutrition. The contributions of knowledge and attitudes of nutrition-conscious behaviors of the mothers to childhood malnutrition has been unclear. The purpose of this study was to explore maternal knowledge of the causes of malnutrition, health-care-seeking attitudes and socioeconomic risk factors in relation to children's nutritional status in rural south India.

METHODS

A case-controlled study was conducted in a rural area in Tamil Nadu, India. Thirty-four cases and 34 controls were selected from the population of approximately 97,000 by using the local hospital's list of young children. A case was defined as a mother of a severely malnourished child under four years of age. Severe malnutrition was defined as having less than 60 percent of expected median weight-for-age. A control had a well-nourished child and was matched by the location and the age of the child. Interviews obtained: (1) socioeconomic information on the family, (2) knowledge of the cause of malnutrition and (3) health-care-seeking attitudes for common childhood illnesses, including malnutrition.

RESULTS

Poor nutritional status was associated with socioeconomic variables such as sex of the child and father's occupation. Female gender (OR = 3.44, p = .02) and father's occupation as a laborer (OR = 2.98, p = .05) were significant risk factors for severe malnutrition. The two groups showed a significant difference in nutrition-related knowledge of mild mixed malnutrition (OR = 2.62, p = .05). No significant difference was apparent in health-care-seeking attitudes. Based on their traditional beliefs, the mothers did not believe that medical care was an appropriate intervention for childhood illnesses such as malnutrition or measles.

DISCUSSION

The results suggested that the gender of the child and socioeconomic factors were stronger risk factors for malnutrition than health-care availability and health-care-seeking attitudes. The father's occupation was a more accurate indicator for malnutrition than household income. These results suggest a need for intensive nutritional programs targeted toward poor female children and their mothers.

Depression in individuals with spinal cord injury: methodological issues

The methodological problems in research related to depression in individuals with spinal cord injury (SCI) are examined. These include relation to normal emotional reactions following injury, the use of physical and vegetative symptoms in the diagnosis of depression, the utilisation of rating scales primarily designed for use in psychiatric populations, the heterogeneity of patients with SCI, the role of preexisting psychiatric morbidity, the selection of controls for comparison and the necessity for multivariate statistical approaches to analysis. The issues and possible solutions are discussed.

N-acetyl-beta-D-glucosaminidase in the localisation of urinary tract infection in patients with spinal cord injury

This study evaluates the pattern of urinary N-acetyl-beta-D-glucosaminidase (NAG) isoenzyme excretion in patients with spinal cord injury (SCI) and its use as a diagnostic tool in localising the site of urinary tract infection (UTI). NAG-B excretion in 27 control SCI patients (mean 207.78 units) was significantly higher than in 10 normal controls (mean 12.6 units) p less than 0.001). The relative isoenzyme distribution as represented by NAG-B/Total NAG percentage is however similar in both groups, 24.27 and 20.38% respectively. NAG-B excretion in 6 SCI patients with upper UTI was not significantly higher than in 12 SCI patients with lower UTI. NAG-B/Total NAG percentage was significantly different between these two groups (35.3% and 24.98% respectively, p less than 0.05). There was no significant difference in NAG-B excretion or NAG-B/Total NAG percentage between control SCI patients and those with lower UTI. The results indicate that there is a non-selective increase in urinary NAG excretion in control SCI patients and those with lower UTI. In SCI patients with upper urinary UTI there is a selective increase in NAG-B excretion. The overlap in enzyme values between the different groups suggests that the test may not be clinically useful in localising the site of UTI.

Mechanistic Interpretation of Rift Valley Formation

The stress distribution on the lithospheric plate due to excess magma pressure is obtained from an exact solution of the three-dimensional theory of elasticity. The analysis indicates that rift valley formation and associated structural and geophysical characteristics can be suitably explained by dike-like intrusions of magma or igneous mush into the lithospheric plate.

Flowage Differentiation

Flowage differentiation is an experimentally demonstrable process capable of causing crystal and chemical fractionation in nature. It is a mechanism for forming olivine-rich rocks in a vertical or steeply dipping position without prior concentration on a flat floor. It explains the field observation that the chilled margin of a mafic intrusion may not be a representative sample of the average composition of the parent magma. In contrast to previous hypotheses of origin for composite dikes, it causes fractionation during and as a result of a single movement of magma rather than by multiple injections.
