Clinico-immunological profile in juvenile rheumatoid arthritis—an Indian experience

From a Pediatric Rheumatology Clinic 361 children diagnosed as juvenile rheumatoid arthritis (JRA) according to American Rheumatism Association-JRA criteria were studied retrospectively for their clinico-immunological profile. The mean age of onset in systemic, pauciarticular and polyarticular onset, JRA subtypes were 5.2, 6.8 and 7.2 years respectively. There was male preponderance in systemic and pauciarticular JRA. In seropositive polyarticular JRA, girls outnumbered boys. The frequency of occurence of systemic, pauciarticular and polyarticular disease was 87 (24%), 108 (30%) and 166 (46%) respectively. The systemic onset disease was dominated by extra-articular manifestations in terms of fever (100%), rash (57%), hepatomegaly (51%) and lymphadenopathy (25%). The pauci- and polyarticular illnesses were commonly dominated by joint involvement, morning stiffness, and in few patients, by extra-articular manifestations also. The joints were involved symmetrically. Most commonly involved joints in order of decreasing frequency were knee, ankle, wrist and elbow in all the subtypes. Anemia and leucocytosis were observed in majority with higher frequency in systemic onset JRA. The rheumatoid factor (RF) was present in 15% of polyarticular JRA. RF was also present in 7 and 9% of patients with pauciarticular and systemic subtypes respectively. The antinuclear antibody was positive in only 3 out of 66 patients in whom the test was carried out. The demographic profile and trends in clinical features were similar to the studies reported on caucasian population with difference in the actual frequency of various clinical features.     

Chronic diarrhea: Causes,presentation, and mangement

Important inroads are being made into understanding the pathophysiology of diarrhea. Clear understanding of key mechanisms should suggest new approaches to combat disease. Exciting developments are occurring in terms of super-ORS solutions, particularly with the promise of short chained glucose polymers and glutamine. Perhaps the most important development is the prospect of a good rotavirus vaccine being available before the end of the decade. Chronic diarrhea seems to be on the increase globally, probably because of the success of ORS. The mechanisms that lead to mucosal injury are elusive, and therapy still largely supportive and empiric. Celiac disease continues to be a puzzle, because of the uncomfortable feeling that a majority of cases may be missed because of atypical presentations. The successful use of long term parenteral nutrition has allowed survival and better charaterization of cases that otherwise would have perished as ‘lethal protracted diarrhea’. Microvillus inclusion disease may be the commonest congenital secretory diarrhea. The role of the recently reported high prevalence of glucoamlase deficiency may be important. Lastly, attention to micronutrients, particularly low vitamin A and probably zinc may prove to be important in prevention and amelioration of diarrhea and growth failure.     

Knee pain and its associations with age,sex, obesity,occupation and living conditions in rural inhabitants of Japan

Factors associated with knee pain were investigated using 871 self-administered questionnaires (405 men and 466 women) from residents aged over 30 years in a rural area of Japan. The prevalence of knee pain increased with age, particularly in women over 50. It was significantly higher in women than in men. Body mass index (BMI) was significantly related to knee pain in women, though not in men. With reference to occupational factors, frequent heavy lifting on the job was significantly associated with knee pain in both men and women, whereas job-related standing and walking showed no such relationship. As for living conditions, residence on rather steep mountain slopes and the habit of sitting on Japanese tatami mats were significant factors related to knee pain in men, but not in women. There was no association of knee pain with the style of toilet (Japanese or Western). After controlling for all significant factors by multiple logistic regression analysis, age, heavy lifting, and residence on steep slopes were found to be independent factors related to knee pain in men; and age, BMI, and heavy lifting were the factors in women.     

Perinatal epidemiology in Belgium

Data on the civil registration of all births and deaths recordedin 1987 in Belgium were analysed following WHO rules. The followingstatistics with significant regional variations were recorded:2.5% of teenage pregnancies, 7% of late pregnancies (35 years),6.1% of low birth weights and 5.3% of preterm deliveries. Pretermbirth rates did not improve during the last decade and are higherthan in neighbouring countries. Infant mortality rate is 9.74per 1000. This rate has remained unchanged since the early 1980sbut the relative importance of post-neonatal mortality is increasing.Congenital anomalies account for 26% of all infant deaths followedby the sudden infant death syndrome (17%). Maternal conditionssuch as eclampsia are related to 29% of the infants' deaths.     

An exploratory study of frequent pain measurement in a cancer clinical trial

The ideal methodology for quality of life (QOL) measurement in cancer clinical trials matches the evaluation to the anticipated outcomes, thereby increasing the likelihood that clinically relevant changes are captured. The present study explored the importance of such methodological tailoring in a phase II trial of paclitaxel and recombinant human granulocyte-colony stimulating factor (rhG-CSF) for metastatic breast cancer. Prior to the trial, clinical observation suggested that frequent short-lived episodes of pain might occur during this treatment regimen. Twenty-one patients provided longitudinal data for at least three cycles of chemotherapy. To assess transient pain, aroutine QOL assessment at baseline and every third cycle was supplemented with pain measurements twice weekly. The interval assessment included a multidimensional QOL instrument (Functional Living Index-Cancer) and measures of psychological state (Rand Mental Health Inventory), symptom distress (Memorial Symptom Assessment Scale), and performance status (Karnofsky Performance Status Score). The frequent pain measurements were acquired using visual analogue and categorical scales for pain intensity (Memorial Pain Assessment Card). From baseline to the end of cycle three, global pain scores declined and the results on other QOL measures were variable. The data obtained using these measures did not reveal the existence of episodic pains. In contrast, the twice weekly pain measurements clearly demonstrated transient severe pains in approximately half the patients. These data highlight the importance of specific measurement of troubling symptoms or other relevant QOL concerns at clinically appropriate intervals during the routine QOL assessment of clinical trials. The additional burden involved in these assessments is warranted if the information derived is highly relevant, would not be adequately captured otherwise and could improve therapy.     

Barriers to follow‐up of abnormal screening mammograms among low‐income minority women

Objective. To describe factors related to compliance diagnostic follow‐up among minority women of low socioeconomic status with abnormal screening mammograms.

Methods. A retrospective cross‐sectional survey using a structured telephone interview. Three cancer screening clinics at an urban inner‐city public hospital. All women with abnormal screening mammograms between September 1990 and January 1992 were eligible; women were interviewed in August 1992. Abnormal mammograms were those requiring specific, non‐routine clinical follow‐up; non‐compliance was defined as delayed follow‐up (four to six months after the date of the mammogram), or no follow‐up at the time of interview (more than 6 months after abnormal).

Results. Sixty‐two of 442 screened women had abnormal results; the overall rate of non‐compliance with follow‐up was 50%. Among the 42 (68%) women who agreed to be interviewed, non‐compliers were less likely to state that they had been told to receive follow‐up than compilers (65% versus 100%; p = 0.008). Non‐compliant women were less likely to have suspicious mammography interpretations (p = 0.05), and more likely to report barriers to follow‐up, such as cost of lost wages and medical care, system barriers, or fears, than compliant women (61.9% versus 9%, p = 0.01). There were no differences between the two groups for age, education, insurance, source of care, family history, knowledge or attitudes.

Conclusions. These preliminary results suggest that follow‐up of low income, minority women with abnormal screening mammograms could be enhanced by improved communication of results. Future studies should extend these findings with larger samples and in other settings and populations.     

Erythromycin succinate in the treatment of acute exacerbations of chronic bronchitis

Summary In 20 patients with an acute exacerbation of chronic respiratory tract infection the effectiveness of oral erythromicin succinate 3×500 mg daily has been tested. The duration of treatment was 10 days in all cases. The criteria of success, in addition to the clinical findings, were the results of bacteriological investigations and assessment of the appearance of the sputum. In all patients sputum and serum concentrations or erythromicin were determined. All pathogens isolated from the sputum of the patients were erythromicin-sensitive. One instance of development of resistance was observed. The drug was well tolerated.     

Long-term results in the surgical treatment of lymphedema

Summary In the irreversible stage of lymphedema corrective surgery is often mandatory. A choice has to be made between two different basic selective procedures. As no totally satisfactory surgical method has as yet been established surgical management is difficult and implies considerable personal responsibility. This is a report on the long-term results of operations carried out on 16 patients between 1958 and 1979 using the so called Charles procedure. It concludes that this radical operation gives an acceptable long-term result in long-standing, elephantiastic primary lymphedema of the lower extremity.     

Matching pain coping strategies to the individual: A prospective validation of the Cognitive Coping Strategy Inventory

The validity of the Cognitive Coping Strategy Inventory (CCSI; Butler et al., 1989) was tested in a prospective fashion. Subjects were randomly assigned to one of three conditions. Some were matched to a strategy for which they received a high CCSI score, some were mismatched to a strategy for which they received a low CCSI score, and some were given a choice of strategies. Those subjects using a matched strategy obtained better threshold and tolerance times on the cold pressor than subjects who used a mismatched strategy. Despite clear differences in exposure to the cold pressor these conditions did not differ from each other in self-reported levels of pain. It was concluded that the CCSI appears to be a valid and useful tool for selecting a coping strategy to help particular individuals manage acute pain. Though the CCSI is relatively easy to administer and score, the comparative costs and benefits of using it must be weighed against the somewhat more efficient approach of simply offering the subject a choice of treatments. Subjects given a choice of strategies performed as well as subjects matched to a strategy on the basis of CCSI scores.     

Granulocyte-macrophage colony stimulating factor does not improve neutrophil oxidative metabolism in a patient with variant X-linked chronic granulomatous disease

Variant X-linked chronic granulomatous disease (CGD) is characterised by a decreased but still measurable respiratory burst and cytochrome b content of phagocytes resulting in a clinically milder form of the disease. We examined the in vivo effect of recombinant human granulocyte-macrophage colony stimulating factor (rh-GM-CSF) on the neutrophil functions of a patient treated for liver abscess. The number of white blood cells was markedly increased at the highest dose of GM-CSF injected (30 g/kg per day). This was mainly due to a large increase in eosinophils and to a lesser extent in neutrophils. No change in the deficient neutrophil respiratory burst nitroblue tetrazolium (NBT)-reduction, superoxide (O ₂ ^– )-production and cytochrome b content was observed during 6 weeks of therapy with increasing doses of GM-CSF. No significant clinical improvement of the liver abscess was observed during treatment with GM-CSF.
