The care and health needs of children in residential care in the Maltese Islands.

OBJECTIVES: To survey the health needs of children in residential care in the Mediterranean Islands of Malta and Gozo. SETTING: Thirteen children's Residential Homes in the Maltese Islands. STUDY DESIGN: Cross-sectional interview survey. METHODS: Carers at the Residential Homes were interviewed using a semistructured questionnaire between June and November 1996. Data related to all the children resident in the homes at the time of the interview were collected including socio-demographic factors, reasons for admission to care, medical needs and medical services received. RESULTS: In all, 309 children, aged birth-16 years-equivalent to 4.2/1000 Maltese children-were in residential care at the time of the study. Fifty-three per cent were boys and 52% were < 8 years of age. The most common reasons for admission into residential care were single parenthood (25%), separated parents and parents unable to offer adequate care (19% each). Admission 'medicals' rarely included a developmental assessment or use of growth charts. Medical and developmental examinations were not carried out on a regular basis and children were medically examined only when required. Dental check-ups were performed more regularly; 30% of the children had a dental check-up every 6 months. Behavioural problems were common affecting 20.7% of all children, followed by chronic bronchial asthma which was present in 7.4%. Developmental delay (global or specific) was reported in 23.3% of children under the age of 4. CONCLUSIONS: Residential care is the predominant form of substitute care for disadvantaged children in Malta and Gozo. The demography of the child population in Residential Homes in these Islands is different from that in other countries, in that 52% of children in residential care are < 8 years of age compared to proportionately more adolescents in other countries. Medical supervision is minimal. A standardised medical and developmental assessment should be established as an essential part of this form of substitute care.

Increased reduction in bone density and skin thickness in postmenopausal women on long-term corticosteroid therapy. A suggested role for estrogen add back therapy.

BACKGROUND: Long term steroid therapy is complicated by osteoporosis and generalised thinning of the skin. These two complications of long term corticosteroid therapy were routinely assessed at the Menopause Clinic of St. Luke's Hospital, Medical School, University of Malta. METHODS: A cross sectional study was performed on 64 postmenopausal women who had been on long term corticosteroids. Each woman had her skin thickness measured using high resolution ultrasound (22 mhz) and their bone density measured using a DEXA Norland. These measurements were compared to a control group (n = 557), a group of women who had sustained osteoporotic fractures (n = 180), and a group of women on hormone replacement therapy (HRT) (n = 399). A longitudinal study on 29 postmenopausal women on corticosteroids was also performed. In this study results were compared between women who in addition to their corticosteroids were on HRT and those who were on corticosteroids alone. RESULTS: The cross sectional study showed the corticosteroid therapy was associated with the thinnest skin thickness measurements mean 0.83 mm. Similarly, low bone density measurements lumbar spine mean 0.81 g/cm2 and left hip mean 0.71 g/cm2 were obtained for this group. The skin thickness in controls and in the HRT groups had a mean thickness of 0.93 mm while that of the osteoporotic fracture group was 0.88 mm. The bone density of the osteoporotic fractures in the fracture group was similar to that of group of women on long term corticosteroids. The lumbar spine had a mean density of 0.81 g/cm2 and left hip that of 0.71 g/cm2. The bone density of the control group and HRT group was significantly higher. The lumbar spine had a mean density of 0.93 g/cm2 and that of left hip was 0.82 g/cm2. The small longitudinal study compared postmenopausal women on long term corticosteroid therapy on HRT to another group who was not on HRT. The longitudinal study over four years revealed a constant increase in skin thickness (mean 6% per year) and bone density (left hip mean 5% per year, lumbar spine mean 5% per year). CONCLUSION: In postmenopausal women on long term corticosteroids, skin thickness and bone density were both decreased, but the addition of HRT as add back improved the situation dramatically. Skin thickness and bone density level in women on long term corticosteroids were comparable to that of women who had sustained osteoporotic fractures. It is therefore suggested that HRT be used as add back therapy in postmenopausal women on long term corticosteroid therapy.

Increased reduction in bone density and skin thickness in postmenopausal women taking long-term corticosteroid therapy: a suggested role for estrogen add-back therapy.

BACKGROUND: Long-term corticosteroid therapy is complicated by osteoporosis and generalized thinning of the skin. These two complications of such therapy were routinely assessed at the Menopause Clinic of St. Luke's Hospital Medical School, University of Malta. METHODS: A cross-sectional study was performed on 64 postmenopausal women who had been taking long-term corticosteroids. Each woman had her skin thickness measured using high-resolution ultrasound (22 MHz) and her bone density measured by dual-energy X-ray absorptiometry (DEXA). These measurements were compared with those of a control group (n = 557), a group of women who had sustained osteoporotic fractures (n = 180) and a group of women taking hormone replacement therapy (HRT) (n = 399). A longitudinal study of 29 postmenopausal women taking corticosteroids was also performed. This study compared results for women who, in addition to their corticosteroids, were taking HRT and for those who were taking corticosteroids alone. RESULTS: The cross-sectional study showed that corticosteroid therapy was associated with the lowest mean skin thickness measurement (0.83 mm). Similarly, low mean bone density measurements for the lumbar spine (0.805 g/cm2) and left hip (0.715 g/cm2) were obtained for this group. The mean skin thicknesses in the control group and the HRT group were 0.93 mm and 0.935 mm, respectively, while that in the osteoporotic fracture group was 0.88 mm. The bone density of the fracture group was similar to that of the group of women taking long-term corticosteroids, with the lumbar spine having a mean density of 0.805 g/cm2 and 0.81 g/cm2, and the left hip having a density of 0.705 g/cm2 and 0.715 g/cm2, respectively. Bone densities were similar for the control group and the HRT group, and higher than that of the corticosteroid or fracture group. The lumbar spine had a mean density of 0.925 g/cm2 in the control group and 0.93 g/cm2 in the hormonally treated group. Both the treated and control groups had similar bone densities of the left hip at about 0.82 g/cm2. The small longitudinal study compared postmenopausal women on long-term corticosteroid therapy taking HRT with another group who were not taking HRT. This 4-year study revealed mean total increases in skin thickness of 6.1% and bone density of 5.5% (left hip) and 14.6% (lumbar spine) in the HRT group, since the start of the study. Conversely, the control group registered reductions over 4 years in both skin thickness (2.8%) and bone density (lumbar spine 4.5% and hip 5.0%). CONCLUSION: In postmenopausal women taking long-term corticosteroids, skin thickness and bone density were both decreased, but the addition of HRT as add-back improved the situation dramatically. Skin thickness and bone density in women taking long-term corticosteroids were comparable to those in women who had sustained osteoporotic fractures. It is therefore suggested that HRT be used as add-back therapy in postmenopausal women taking long-term corticosteroid therapy.

Carotid artery wall changes in estrogen-treated and -untreated postmenopausal women.

OBJECTIVE: To investigate whether the thickness of the layers of the carotid artery (externa, media, and intima) are affected by menopause and its treatment with hormone replacement therapy (HRT). METHODS: One hundred twenty-nine postmenopausal women were recruited sequentially and classified into three groups. Forty-six were taking oral HRT, 32 had estradiol implants, and 51 had never taken HRT. The three layers of the externa wall of the carotid artery were identified and measured by high-resolution ultrasound. RESULTS: Women with implants had thicker carotid artery wall measurements (0.84 +/- 0.26 mm) than the other groups. The media (0.32 +/- 0.11 mm) was significantly thicker in the implant group. This layer has a high connective tissue component, including collagen type I, collagen type III, and elastin fibers. The intima layer was thinner (0.25 +/- 0.09 mm) in the oral HRT group compared with controls (0.29 +/- 0.1 mm). A statistically significant higher intima-media ratio (1.17 +/- 0.05) was calculated for the control group, compared with both the oral HRT (0.92 +/- 0.04) and implant groups (0.94 +/- 0.03). CONCLUSION: Our findings suggest that HRT given to postmenopausal women influences differentially the layers of the carotid artery. Hormones seem to encourage thickening of the layers with the highest connective tissue component (externa and media) and to delay thickening of the atheromatous intima layer. These effects on the vascular system may be partly responsible for the cardioprotection attributed to HRT.

Changes in bone collagen markers and in bone density in hormone treated and untreated postmenopausal women.

OBJECTIVE: This study aims to compare bone mineral density measurements (BMD), pyridinium crosslink levels and pyridinium crosslink levels in untreated and hormone treated postmenopausal women. METHODS: A cross-sectional study comparing biophysical (BMD) and biochemical (pyridinium crosslink and PCICP) parameters in a group of untreated postmenopausal women (n = 145) to a group of postmenopausal women on hormone replacement therapy (HRT) (n = 92). RESULTS: Untreated postmenopausal women compared to postmenopausal women on HRT had higher Osteoblastic and Osteoclastic activity. Procollagen I C-end terminal peptide (PCICP) was 11.3% lower in the women on HRT compared to controls whilst crosslinks were 27.2% lower than in controls. This seems to indicate that women on HRT had a bone balance that was higher compared to the control group (15.9%). The difference in bone density of L2-L4 between the two groups was (16.1%). CONCLUSIONS: This study seems to indicate that postmenopausal women receiving HRT readjust their bone remodelling so that although osteoblastic function is reduced, there is a much greater deduction in osteoclastic function and this results in an overall higher bone mass observed in the BMD of women on HRT.

The epidemiology of osteoporotic fractures in a Mediterranean country.

A population study was carried out over a period of 3 years (1987-1989) to determine the incidence of osteoporotic fractures. Fractures diagnosed in the two acute hospitals of the Maltese Islands were collected and classified according to the fracture site, age, sex, and patient's residence. Fractures in the Maltese Islands can only be diagnosed and adequately treated in these two general hospitals. A total of 8780 fractures were examined. Fracture of the neck of the femur was the most common fracture for which patients were admitted to the hospital. There were twice (1.96) as many females as males hospitalized for this fracture, giving an annual incidence of 262/100,000 females to 134/100,000 males over the age of 45. The fracture incidence was 2-3 times less than that found in North European countries, but was similar to the fracture rates obtained in Mediterranean studies. Fracture radius was the most frequent fracture treated on an outpatients basis. In over 45-year-olds, the female predominance persisted, giving a ratio of 3.65:1. This gave an annual incidence of 452/100,000 females to 150/100,000 males. Again, the fracture incidence obtained was significantly lower than that of Northern European countries. Other long bones showed a similar female to male (F:M) ratio in the cohort over 45 years of age. The bones showing this F:M ratio were the humerus (3.9:1), fibula (1.89:1), and tibia (1.6:1). Below 45 years of age males had more fractures than females for any bone studied.(ABSTRACT TRUNCATED AT 250 WORDS)
