Age, gender, quality of life and psychological distress in patients hospitalized with psoriasis.

BACKGROUND: Psoriasis has a great impact on the quality of life of patients, and the ageing population is an important public health issue. OBJECTIVES: To investigate whether older patients with psoriasis have a different impairment in quality of life compared with younger patients, considering level of severity, duration of disease, gender and psychological distress. METHODS: The study was performed between February 2000 and February 2002 at the inpatient wards of the Dermatological Institute IDI-IRCCS, Rome, Italy, in the framework of a large project on clinical, epidemiological, emotional and quality of life aspects of psoriasis (IMPROVE study). This is a hospital-based cross-sectional study, with measures of quality of life (Skindex-29, Dermatology Life Quality Index and Psoriasis Disability Index) and of psychological distress, generic (12-item General Health Questionnaire) and psoriasis-related (Psoriasis Life Stress Inventory), all self-assessed by patients. We compared the mean scores of each quality of life instrument in patients aged < 65 years and >/= 65 years, in subsets of patients based on clinical and sociodemographic characteristics. RESULTS: We analysed 936 patients hospitalized at IDI-IRCCS with a diagnosis of psoriasis. Quality of life was significantly more impaired in the older group for all the Skindex-29 scales, and psychological distress was higher in older patients. In particular, older women suffering from anxiety or depression had the greatest impairment in quality of life. The results were somewhat different using the other quality of life instruments. CONCLUSIONS: These results should alert dermatologists that similar levels of clinical severity in psoriasis may be associated with different levels of quality of life and psychological distress of patients. Particular attention should be devoted to older patients, and especially to older women.

Measuring quality of life of patients with different clinical types of psoriasis using the SF-36.

BACKGROUND: Different specific and generic instruments are used to evaluate quality of life in dermatology, but their interrelationship is not well known. OBJECTIVES: To describe the quality of life in patients with different clinical types of psoriasis using the 36-item short form of the Medical Outcomes Study questionnaire (SF-36), and to study its correlation with dermatology-specific instruments. METHODS: We conducted a cross-sectional study of 380 inpatients with psoriasis. SF-36 mean scores were compared with the norms for medical and psychiatric disorders. Quality of life was also measured by both dermatology-specific (Skindex-29 and Dermatology Life Quality Index, DLQI) and psoriasis-specific instruments (Psoriasis Disability Index, PDI, and the Impact of Psoriasis Questionnaire, IPSO). A specific (Psoriasis Life Stress Inventory, PLSI) and a generic (12-item General Health Questionnaire, GHQ-12) measure of psychological distress was also used. A cluster analysis was performed to study the relationship among the different questionnaires. RESULTS: Our study population showed SF-36 physical health scores similar to minor medical conditions (e.g. physical functioning 79 for psoriasis, 80 for minor medical conditions, and 57 for severe medical conditions), but mental health scores quite similar to psychiatric illnesses (e.g. mental health 57 for psoriasis, 81 for minor medical conditions, 79 for severe medical conditions, and 53 for psychiatric conditions). The SF-36 showed two distinct patterns of impairment of quality of life, with a greater burden of disease for palmoplantar, pustular and arthropathic psoriasis. SF-36 scales tended to form separate clusters from the other dermatology-specific quality of life instruments. CONCLUSIONS: A generic quality of life instrument (e.g. the SF-36) provides information that is complementary to that derived from dermatological questionnaires, and may give further insight in the evaluation of the burden of psoriasis.

Burnout and job satisfaction comparing healthcare staff of a dermatological hospital and a general hospital.

BACKGROUND: Psychological distress among healthcare professionals can have negative effects on the well-being of the professionals and also on the quality of care they provide to patients. OBJECTIVES: To evaluate burnout and job satisfaction of dermatologists and nurses working with dermatological patients compared with physicians and nurses of other specialties. METHODS: A self-completed anonymous questionnaire was distributed to the personnel of two hospitals in Rome, Italy: a dermatological hospital (IDI) and a general hospital (GH), belonging to the same non-profit organization. Standardized instruments were used to assess burnout (Maslach Burnout Inventory) and job satisfaction. Multiple logistic regression was used to examine the association between burnout and working in dermatology vs. other specialties, job satisfaction, years of employment and respondents' sex and age. RESULTS: We distributed 929 questionnaires to clinical and non-clinical staff of IDI and 494 questionnaires to the GH staff (response rates: 53% at IDI and 50% at the GH). Among respondents there were 67 physicians and 59 nurses at IDI and 70 physicians and 148 nurses at the GH. Subsequent analyses refer only to this clinical subsample. Factor analysis showed that among physicians and nurses the two main factors explaining job satisfaction were respondents 'satisfaction with the management of their unit' and 'opportunities for personal growth'. Among nurses the likelihood of burnout decreased significantly with higher levels of job satisfaction [odds ratio (OR) = 0.78; 95% confidence interval (95% CI) 0.7-0.9] and working in dermatology compared with other specialties (OR = 0.46; 95% CI 0.2-0.9). Among physicians a lower likelihood of burnout was associated with job satisfaction (OR = 0.66; 95% CI 0.5-0.8) and older age (OR = 0.28; 95% CI 0.1-0.8). CONCLUSIONS: Among both physicians and nurses, job satisfaction was associated with a lower likelihood of burnout, independently of clinical specialty and other factors. Burnout was similar for dermatologists and other specialists. Nurses of the GH compared with those working in dermatology had a higher probability of burnout and were significantly less satisfied with the management of their units and with opportunities for personal growth.

Effects of patient satisfaction with care on health-related quality of life: a prospective study.

OBJECTIVES: To evaluate the effect of patient satisfaction on health-related quality of life among dermatological outpatients, independently of patients' sociodemographic, and clinical characteristics. DESIGN: Prospective cohort study. Satisfaction was evaluated with a standardized questionnaire three days after the visit by telephone interview. Quality of life and psychiatric disorders were measured with validated instruments (Skindex-29 and Ghq-12) before the dermatological visit and after four weeks. At the four week interview also self-reported medication adherence was assessed. SETTING: Outpatient clinics of a large dermatological hospital in Rome, Italy. PATIENTS: A consecutive sample of 1389 outpatients was approached, and 52% agreed to participate. Inclusion criteria were met by 424 patients, and 396 (93%) of them completed the study. MAIN OUTCOME MEASURES: Improvement in health related quality of life. RESULTS: At multivariate analysis satisfied patients have approximately twice the odds for an improved quality of life on the emotions scale (OR = 1.99; 95%CI 1.1 to 3.7; P = 0.03) and on the functioning scale (OR = 2.2; 95%CI 1.1 to 4.7; P = 0.03). Patients with psychiatric disorders at baseline were less likely to have an improved quality of life on the functioning scale (OR = 0.3; 95%CI 0.2 to 0.8; P = 0.01). CONCLUSIONS: This is the first prospective study showing that patient satisfaction and psychiatric disorders have a significant effect on quality of life improvement among dermatological patients, independently of patient characteristics. Particular attention should be devoted to improving physicians' interpersonal skills, the major component of patient satisfaction.

Satisfaction with care in vascular surgery inpatient units.

OBJECTIVE: to identify and solve problems concerning satisfaction of inpatients in three different vascular surgery units. MATERIALS AND METHODS: a self-administered non anonymous questionnaire was submitted. Four dimensions of patients' satisfaction and a measure of overall satisfaction were evaluated. For each of them a logistic regression model was elaborated. RESULTS: one hundred and fifty-six eligible patients agreed to participate. For the "overall satisfaction" 56% rated the care received as excellent; patients completely satisfied for "treatment and related information" were 76%; for the "availability of staff" 96%, for "helpfulness and communication by staff" 56% and for "management of patient's complaint by medical staff" 86%. Logistic regression analysis showed, after adjustment for relevant background factors, a statistically significant difference among units of care for the overall satisfaction. CONCLUSIONS: the study highlighted the importance of considering in vascular units the patients' satisfaction as an essential component of quality of care independently of the severity of cases. The hospital management recognised the low level of communication by the staff as one of the hospital bottle-necks and tried to solve a logistic problem identified as responsible for a low score in the overall satisfaction in one unit.

Effects of salmon calcitonin on the bone loss induced by ovariectomy.

We present the results of a 12-month clinical study assessing the effects of synthetic salmon calcitonin (sCT) on a group of fertile white women who had undergone ovariectomy for uterine fibromatosis. The study was performed to verify whether CT can prevent the loss of bone mass and the changes in calcium-phosphorus metabolism associated with acute estrogen deficiency. The study consisted of an initial double-blind phase of 6 months, followed by a 6-month open period. Treated patients were given 100 MRC U of synthetic salmon CT injected i.m. in the morning, every other day, starting on the 7th day after the operation and continued for 12 months. Control patients received a placebo injection for the first 6 months; subsequently, they too were treated with sCT i.m. every other day for 6 months at the same dose as the 12 month-treated group. All patients received 500 mg of elementary calcium p.o., b.i.d. Bone mineral content (BMC) was measured at the extreme distal radius of the nondominant arm by a dual photon bone densitometer which utilizes two radio nuclides, 241 Am and 125 I, with energies of about 60 and 30 KeV. Biochemical parameters of the calcium-phosphorus metabolism were also measured. After 12 months of study, no significant changes of BMC were observed in the 12 months sCT treated group, while control patients, treated 6 months after the ovariectomy, showed a significant decrease in BMC values.(ABSTRACT TRUNCATED AT 250 WORDS)

Acute hypocalcemia enhances prolactin levels: a study before and after oophorectomy.

The effect of acute hypocalcemia on serum prolactin values was investigated in 13 female subjects before and after oophorectomy. An infusion of disodium-EDTA (50 mg/kg b.w., for 120 min) was administered to each patient. Ionized calcium, immunoreactive parathyroid hormone and prolactin serum levels were determined 15 min prior to the infusion, at the beginning of each infusion and thereafter at every 30 min interval. The decrease in serum ionized calcium induced by Na2-EDTA infusion was not influenced by surgery. Serum prolactin and parathyroid hormone values before and after oophorectomy showed a significant (p less than 0.01) increase at 90 and 120 min. The maximum serum prolactin increase was achieved at 120 min and was not influenced by oophorectomy. The results demonstrate that acute hypocalcemia increases serum prolactin levels in female subjects and suggest a possible role for parathyroid hormone and dopaminergic system, even if their interaction remains speculative.

Pathogenetic aspects of involutional osteoporosis.

The pathogenetic factors of postmenopausal and senile osteoporosis are reviewed. Both postmenopausal and senile osteoporosis occur as a result of a defective regulation of bone remodelling which leads to a negative uncoupling between bone resorption and bone formation. Systemic and local factors contribute to the development of the phenomenon. While studies of the systemic factors involved in age-related bone loss are well advanced, although still incomplete, the study of the local factors responsible at a tissue level for the negative skeletal balance has barely begun.

Serum osteocalcin in primary hyperparathyroidism: short-term effect of surgery.

This study has been carried out in order to evaluate both serum osteocalcin levels in primary hyperparathyroidism and their changes following surgery. Twenty-one consecutive patients were studied (12 females and 9 males, aged 46 +/- 17 years). Preoperatively, a better correlation was found between serum osteocalcin and serum alkaline phosphatase activity (r = 0.79, p less than 0.001) than between serum osteocalcin and the 24-hour urinary hydroxyproline/creatine ratio (r = 0.55, p less than 0.05). Following the surgical removal of hyperfunctioning parathyroid tissue, a modest but significant decrease was observed in the serum levels of osteocalcin; this reached a nadir during the 1st or 2nd day after the removal of the adenoma. The mean levels then tended to rise, so that the values measured on the 7th day after parathyroidectomy (12.4 +/- 2.5 ng/ml) were not significantly different in respect to basal values (13.6 +/- 2.7 ng/ml). A parallel pattern was also noted as concerns the serum alkaline phosphatase activity. On the contrary, mean values of serum immunoreactive parathyroid hormone (243 +/- 78 vs. 58 +/- 11 pmol/l; p less than 0.02) and serum calcium (12.4 +/- 0.5 vs. 9.2 +/- 0.3 mg/dl; p less than 0.01) were significantly reduced and mean values of serum phosphorus (2.4 +/- 0.2 vs. 3.1 +/- 0.2 mg/dl; p less than 0.001) significantly higher in comparison to basal values.(ABSTRACT TRUNCATED AT 250 WORDS)

Recurrent hyperparathyroidism: a study of 3 cases with evaluation of some pathogenetic and clinical aspects.

Three patients with recurrent hyperparathyroidism (15, 8 and 3 years respectively, after the first operation) are described in order to establish the causes and define the clinical characteristics of the disease. The observation that in the present series recurrent hyperparathyroidism was associated either with an adenoma (two cases) or a carcinoma (one case), appears to stress the possibility of the pathological involvement of one gland even though recurrent hyperparathyroidism should be considered due to the chronic extrinsic stimulation of the parathyroid glands. The severity of the clinical and metabolic picture observed at the time of the first diagnosis and/or at the time of recurrence together with the simultaneous presence of bone and stone disease in the patients described is of particular interest. The cases reported underline the importance of carrying out careful metabolic investigations in patients with hyperparathyroidism not only before but also for a prolonged period of time after operation.

Normal calcitonin secretion in acromegaly.

Calcium and phosphate metabolism has been studied in eight patients with active acromegaly. Plasma calcium, phosphate, alkaline phosphatase, creatinine and parathyroid hormone levels were in the normal range in all patients, while urinary calcium excretion, calcium/creatinine ratio and hydroxyproline were higher than in controls (p less than 0.01, p less than 0.01, p less than 0.02, respectively). Basal plasma calcitonin levels were in the normal range and stimulation with calcium (3 mg/kg body weight in 10 min) showed similar calcitonin responses in acromegalic and normal subjects. Our data show that in normocalcemic acromegaly with high bone turnover calcitonin secretion is not abnormal.

Basal and stimulated calcitonin secretion in primary hyperparathyroidism before and after parathyroidectomy.

To investigate calcitonin secretion in primary hyperparathyroidism, basal and stimulated (3 mg Ca++/kg body weight/10 min) immunoreactive calcitonin plasma levels were studied before parathyroidectomy. Plasma calcitonin levels were raised in 50% of patients regardless of sex, but a significant correlation between basal plasma calcium and calcitonin was found only in males. A reduced calcitonin response to calcium infusion was observed in all patients. Parathyroidectomy invariably induced a normalization of calcitonin basal levels. Our findings confirm the existence of a decreased parafollicular cell reserve probably as a consequence of the persistent hypercalcemic state in hyperparathyroid patients and suggest that it is more frequent in females.

Pathophysiological studies in hypercalciuric and normocalciuric stone formers.

This study has been carried out in order to investigate the effects of a standard oral calcium load in 18 hypercalciuric and 18 normocalciuric recurrent stone formers. Following oral loading there was not a significant difference in the two groups studied, as far as serum calcium increment was concerned; however, urinary calcium excretion was significantly greater in hypercalciuric stone formers. The results obtained, although they do not exclude the presence of intestinal calcium hyperabsorption, seem to demonstrate the existence of a diminution of renal tubular calcium reabsorption in patients with idiopathic hypercalciuria.

Changes in mineral content and biochemical bone markers at the menopause.

Serum alkaline phosphatase activity, serum bone gamma-carboxyglutamic acid protein, urinary hydroxyproline and bone mineral content were simultaneously measured in 30 age-matched pre- and postmenopausal women in order to define the temporal relationship between skeletal turnover and bone loss. In postmenopausal women, mean values of phosphatase activity, serum bone gamma-carboxyglutamic acid protein and urinary hydroxyproline were significantly higher, and mean values of mineral content were significantly lower than in premenopausal women. A marked loss of bone mineral content together with a persistent increase in skeletal turnover is already evident shortly after the menopause.

Acute effects of removal of parathyroid adenoma on plasma and urinary hydroxyproline levels.

This study was carried out to investigate early effects of parathyroidectomy (PTx) on bone matrix collagen metabolism. Eleven patients suffering from primary hyperparathyroidism were studied by measuring urinary excretion of hydroxyproline (OHPr) and cAMP in samples collected before PTx and, on the day of surgery, at intervals of 1-3 h for the first 10 h and then at longer intervals. In six patients nondialyzable urinary OHPr and free plasma aminoacid levels were also assayed. We found that the average period required for OHPr/Cr ratio and plasma OHPr to reach normal values was longer than the mean time required for cAMP/Cr ratio to reach normal limits. In all patients the total amount of nondialyzable OHPr decreased in the first 24 h after PTx but thereafter a daily increase in the urinary excretion of nondialyzable component was seen, so that the fractional amount of nondialyzable OHPr in the fourth postoperative day (26.8 +/- 5.2 SE) was significantly higher than that of preoperative one (6.1 +/- 1.0; p less than 0.02). Our results confirm that PTx induces a reduction in the rate of bone collagen resorption and indicate that changes of OHPr/Cr ratio and free plasma OHPr values may be considered useful indices of successful parathyroid surgery, even though they lag behind those of cAMP. The different behavior of total and nondialyzable OHPr after surgery indicates that acute deficiency of parathyroid hormone induces a positive uncoupling of the two processes of bone remodeling, thus supporting the view that the acute direct effect of the hormone on bone formation is an inhibition of this process.
