Femoral neck shaft angle in men with fragility fractures.

Introduction. Femoral neck shaft angle (NSA) has been reported to be an independent predictor of hip fracture risk in men. We aimed to assess the role of NSA in UK men. Methods. The NSA was measured manually from the DXA scan printout in men with hip (62, 31 femoral neck and 31 trochanteric), symptomatic vertebral (91), and distal forearm (67) fractures and 389 age-matched control subjects. Age, height, weight, and BMD (g/cm(2): lumbar spine, femoral neck, and total femur) measurements were performed. Results. There was no significant difference in mean NSA between men with femoral neck and trochanteric hip fractures, so all further analyses of hip fractures utilised the combined data. There was no difference in NSA between those with hip fractures and those without (either using the combined data or analysing trochanteric and femoral neck shaft fractures separately), nor between fracture subjects as a whole and controls. Mean NSA was smaller in those with vertebral fractures (129.2° versus 131°: P = 0.001), but larger in those with distal forearm fractures (129.8° versus 128.5°: P = 0.01). Conclusions. The conflicting results suggest that femoral NSA is not an important determinant of hip fracture risk in UK men.

Quality of life, morbidity, and mortality after low trauma hip fracture in men.

BACKGROUND: Osteoporotic hip fractures have been extensively studied in women, but they have been relatively ignored in men. OBJECTIVE: To study the mortality, morbidity, and impact on health related quality of life of male hip fractures. METHODS: 100 consecutive men aged 50 years and over, with incident low trauma hip fracture, admitted to Royal Cornwall Hospital, UK during 1995-97, were studied. 100 controls were recruited from a nearby general practice. Mortality and morbidity, including health status assessed using the SF-36, were evaluated over a 2 year follow up period. RESULTS: Survival after 2 years was 37% in fracture cases compared with 88% in controls (log rank test 62.6, df = 1, p = 0.0001). In the first year 45 patients died but only one control. By 2 years 58 patients but only 8 controls had died. Patients with hip fracture died from various causes, the most common being bronchopneumonia (21 cases), heart failure (9 cases), and ischaemic heart disease (8 cases). Factors associated with increased mortality after hip fracture included older age, residence before fracture in a nursing or residential home, presence of comorbid diseases, and poor functional activity before fracture. Patients with fracture were often disabled with poor quality of life. By 24 months 7 patients could not walk, 12 required residential accommodation, and the mean SF-36 physical summary score was 1.7SD below the normal standards. CONCLUSIONS: Low trauma hip fracture in men is associated with a significant increase in mortality and morbidity. Impaired function before fracture is a key determinant of mortality after fracture.

Hand bone densitometry in rheumatoid arthritis, a five year longitudinal study: an outcome measure and a prognostic marker.

OBJECTIVE: To investigate whether hand bone mineral content (BMC) measurement is an outcome measure for RA and whether the early changes in hand BMC predict functional disability. METHODS: Tender and swollen joints in hands and body, HAQ score, Larsen score on hand radiographs, serum CRP, and hand BMC measurement by DXA were studied every six months for five years in 40 patients with early RA. At the final visit, patients completed the SF-36 and Duruoz hand function questionnaires. RESULTS: All patients completed two years and 29 completed five years' follow up. Hand BMC worsened over the first three years (percentage loss from baseline: mean (SD) -5.5 (7.2), -7.5 (8.4), -9.8 (9.4)) and stabilised over last two years (-9.9 (8.8), -10 (7.8)). Baseline disease activity and function correlated with hand BMC loss at five years (swollen joints in hands: r=-0.38, p=0.043; swollen joints in body: r=-0.47, p=0.01; HAQ: r=-0.52, p=0.004). Percentage change in hand BMC over five years correlated with SF-36 physical function (r=0.61, p<0.01), hand function (r=-0.64, p<0.01), HAQ score (r=-0.63, p<0.01) at five years. Relative risk of bad hand functional outcome at five years was significantly higher for patients with hand BMC loss of >/=1.17 g (smallest detectable difference) than for patients with less bone loss within the first six months (OR=6.9, 95% CI 1.3 to 34.5, p<0.02). CONCLUSION: Early loss of hand BMC in patients with RA is a composite marker of disease activity and functional status and can predict poor functional outcome.

Osteoporosis in men.

Osteoporosis is characterized by a reduction in bone density, associated with skeletal fragility and an increased risk of fracture after minimal trauma. Although osteoporosis is generally considered to be a condition affecting post-menopausal women, it is now clear that substantial bone loss occurs with advancing age in men, such that up to 20% of symptomatic vertebral fractures and 30% of hip fractures occur in men. This chapter highlights the incidence and prevalence of osteoporotic fractures in men and reviews the associated morbidity, excess mortality and health and social service expenditure. The determinants of peak bone mass and bone loss in men are discussed, as is the pathogenesis of osteoporosis and vertebral and hip fractures. The criteria for the diagnosis of osteoporosis in men are reviewed, together with the most appropriate investigations for secondary osteoporosis. The management of osteoporosis in men is also discussed, highlighting the most appropriate treatment options.

Bone mineral density, hip axis length and risk of hip fracture in men: results from the Cornwall Hip Fracture Study.

Bone mineral density (BMD) and hip axis length (HAL) are important determinants of fracture risk in women. There are, however, few data concerning their predictive risk in men. The aim of this study was to determine the relationship between BMD, HAL and the risk of hip fracture in men. A case-control design was used. Cases were men aged 50 years and over with a minimal-trauma hip fracture admitted to the Royal Cornwall Hospital, Truro, during 1995-1997. Controls were recruited from a large general practice within the catchment area of the hospital. Subjects were invited for assessment of BMD at the lumbar spine and proximal femur, using dual-energy X-ray absorptiometry. HAL was assessed using machine software. Data concerning BMD were available in 62 fracture cases and 100 controls. After adjusting for age, height and weight, a reduction in BMD was associated with a significant increase in the risk of hip fracture [odds ratio (OR) 1.8-4.0 per standard deviation (SD) reduction, depending on site]. HAL was similar in both fracture and control groups (12.0 cm vs 12.0 cm). After adjusting for height, there was no association between HAL and the risk of hip fracture (OR per 1 SD increase in HAL = 0.9; 95% confidence interval 0.6, 1.3). Compared with those with a cervical fracture (n = 31), those with an intertrochanteric fracture (n = 31) had lower BMD at all skeletal sites, though this was significant for the trochanteric site only. It is concluded that BMD though not hip axis length is a risk factor for low-trauma hip fracture in Caucasian men.

Low dose amitriptyline in ankylosing spondylitis: a short term, double blind, placebo controlled study.

OBJECTIVE: To define the effect of low dose amitriptyline on fatigue, pain, and stiffness in patients with ankylosing spondylitis (AS). METHODS: One hundred consecutive patients with AS were randomized to receive low dose amitriptyline up to 30 mg nightly or placebo for 2 weeks. Patients were assessed by the Bath Ankylosing Spondylitis Disease Activity (BASDAI) and Functional (BASFI) Indices pre and post-treatment. RESULTS: Eighty-eight patients (44 amitriptyline, 44 placebo) completed the study. Eight (5 amitriptyline, 3 placebo) stopped treatment because of side effects (e.g., drowsiness, dryness of mouth) and 4 provided insufficient data. Compared to placebo, the patients taking amitriptyline showed significantly greater improvement in restful sleep (66 vs 20%; p < 0.001) and their disease activity scores [BASDAI amitriptyline 1.18 (23%) vs placebo 0.52 (10%); p = 0.024]. All other variables showed a trend to greater improvement by amitriptyline, although the differences were not statistically significant. CONCLUSION: (1) In a 2 week study, low dose amitriptyline significantly improved sleep in AS and was well tolerated; (2) as defined by BASDAI, there was a significant reduction in disease activity with amitriptyline; (3) compared to placebo, there was a nonsignificant trend toward improvement in function; and (4) in spite of improvement in pain, fatigue, and sleep with amitriptyline, stiffness was not increased.

Spectrum of clinical and laboratory characteristics of HIV infection in northern India.

To define the impact of HIV infection in India, the clinical and laboratory profile and the correlation of CD4 count to the likely opportunistic infection in a cohort of 134 HIV positive patients in Northern India was analysed. Majority of the patients, 72% and 67.8% (children and adults respectively) were asymptomatic, having been detected during routine screening and maintained that status for a median follow-up period of 3 years. Among the symptomatic patients, oropharyngeal candidiasis was the most common opportunistic infection followed closely by tuberculosis (both pulmonary and extra pulmonary) around 3.6-4.0 years from probable HIV infection with a median CD4 of 420-578 per cmm. Infection with Cryptococcosis, Cryptosporidiosis and cytomegalovirus occurred only after a significant fall in CD4 to < 100/cmm usually around 8-10 years from probable HIV infection. Pneumocystis carinii pneumonia was the terminal event among the 12 deaths at a mean CD4 count of 6/cmm. Non specific constitutional symptoms like fever, prolonged diarrhoea and significant weight loss were frequent. In general, the clinical profile of Indian patients with HIV bears much resemblance to African countries owing perhaps to the similar background of poverty, malnutrition and endemic infection.

Behçet's disease in India: a clinical, immunological, immunogenetic and outcome study.

The clinical and laboratory profile of 58 consecutive patients satisfying the ISG 1990 criteria for the diagnosis of Behçet's disease was analysed. It appears that Behçet's disease in India is predominantly 'mucocutaneous' and 'arthritic'; 'ocular' and 'neuro' Behçet's being uncommon. In comparison to published literature, the onset of disease in this part of the world is significantly delayed. The pathergy test is rarely positive. There is no significant difference in clinical presentation and laboratory investigations between children and adults with this disease; also, no sex difference was observed. A combination of oral steroids and colchicine gives good relief in most cases. Preliminary observations seem to reflect no definite association of any known class I antigen to disease in this part of the world. A detailed study on immunogenetics is underway.

Does mixed connective tissue disease exist in India?

One thousand consecutive patients with systemic connective tissue diseases were screened clinically and serologically to determine the existence of mixed connective tissue disease (MCTD) in the Indian population. After completion only three patients could be diagnosed as having MCTD using the standard diagnostic criteria. The results of this study point to MCTD existing but it appears to be a rare entity in the Indian population.

Adult onset Still's disease in northern India: comparison with juvenile onset Still's disease.

The present study compared the clinical and laboratory picture, the disease course and outcome in 31 patients having adult onset Still's disease (AOSD) with 23 patients having juvenile onset Still's disease (JOSD). The median age at disease onset was 20 and 7 yr for AOSD and JOSD patients, respectively. On analysing and comparing our data on these two groups, no significant differences emerged except that adults had a significantly lower time interval from disease onset to remission as compared to juveniles. Upon comparison of data on our AOSD patients with that published from abroad, rash, adenopathy and sore throat were less frequent. No clinical or laboratory variables were found to predict the subsequent disease course and outcome in either group. The functional outcome was good in about 70% of both groups and mortality was low. It is concluded that the clinical picture and outcome in AOSD is similar to that of JOSD.

Sociodemographic characteristics of HIV infection in northern India.

134 patients testing positive for HIV antibody during the period 1986-1993 were included in the present study. An in-depth analysis of the subjects revealed that the adult males seemed to have the highest propensity for HIV infection in this part of the country. Marital status had no bearing on incidence and route of seropositivity. This was not so in females. Extramarital heterosexual contact was the mode of HIV acquisition in adults in contrast to blood transfusion in children. Clinically, most of these patients were still asymptomatic. At presentation, oral Candidiasis was common. Pneumocystis carinii pneumonia (PCP) was the leading cause of death.

PIP: Data are analyzed from 134 HIV positive individuals who were referred to the National AIDS Control Organization of the Indian Government for clinical management during June 1986-June 1993. The center was a major referral center for northern India. HIV was determined by enzyme linked immunosorbent assay (ELISA). Retesting was conducted. The population was grouped as under and over 13 years of age. Laboratory testing was performed in order to determine the absolute lymphocyte count (ALC), the absolute and percentage of CD4+ and CD8+ lymphocyte counts and CD4/CD8 ratios, immunoglobulins, and delayed-type cutaneous hypersensitivity (DTH). Findings indicated an increase in HIV positive cases over time and a greater number of adults who were HIV positive. The mean age was 27.2 years for males and 22.2 years for females. The youngest age was 1.5 years. 116 HIV positive people were Indians, and most lived in metropolitan areas of northern India. 25 were children. 25 lived in neighboring villages of Haryana, Punjab, and around Delhi. Marital status appeared to be unrelated to HIV status. 51 men were single and 46 were married and seropositive due to sexual contacts. 4 women were single and 8 were married. Of the 4 single women, 2 were sexually very active with multiple partners. 6 of the 8 married females acquired HIV infection through their spouses. The other 2 received HIV infected blood transfusions. 39.5% of men and 75% of women acquired HIV infections from heterosexual contacts. 29% of transmission was due to contaminated blood and blood products. The HIV infected male population comprised mainly businessmen and defense personnel. HIV infected persons came mainly from the Bombay-Pune area. 66.6% of persons infected from contaminated blood were from Delhi. Asymptomatic PGL and ARC screenings were the common reason for referral to the center. 13 of the 134 have already died. The most common cause of death was Pneumocystis carinii pneumonia. The most common opportunistic infection was candidiasis.

Profile of HLA-B27-related 'unclassifiable' seronegative spondyloarthropathy in females and its comparison with the profile in males.

Unclassifiable seronegative spondyloarthropathy (SSA) syndrome is primarily considered to be an affliction of males. In this report from northern India, 25 HLA-B27 antigen positive females with this condition are described and compared with 39 HLA-B27-positive males with the same disease. All these patients presented with typical features of spondyloarthropathy such as predominantly lower limb synovitis, enthesopathy and inflammatory spinal pain. The onset was insidious in 56% of the females and in 64% of the males. The mean age of onset as also the mean duration of symptoms prior to diagnosis were significantly higher in females (26.2 vs 19.4 yr and 8 vs 2 yr, respectively). A mono- or oligo-arthritis was seen in 52% of the females and in 53% of the males, but the average number of joints involved was less in females (4.8 vs 7.7). Lower limb joints alone were involved in 56% of the females and 49% of the males, with the knees, ankles and hips being most commonly involved, often asymmetrically. The mean degree of symmetry was significantly lower in females (62 vs 76). Ninety-two per cent of females and 74% of males had inflammatory spinal pain. Radiographic sacroiliitis was demonstrable in 56% females and 74% males. It is concluded that 'unclassifiable' SSA syndrome is not infrequent in females but is diagnosed late. Fewer joints tend to be involved and there is greater tendency towards asymmetry in females.
