Severe obesity with co-morbidity such as diabetes mellitus, cardiac failure, obesity hypoventilation, degenerative bone diseases and increased incidence of malignancy give rise to shorter life expectancy and have an impact on quality of life. This results in higher costs of health care and work absence. Surgical procedures have become commonplace in the therapy of morbid obesity because of the infrequent success of medical treatment. We performed a horizontal gastroplasty by laparoscopic adjustable silicon gastric banding (LASGB) on 60 patients between 1. 11. 1995 and 28. 2. 1997. The average excess above normal weight was 62 kg, the median BMI (Body-Mass-Index) was 46.44 kg/m2. Fifty-nine procedures were performed by the laparoscopic method and one with an open technique. The average postoperative hospital stay was five days. Due to dorsal slipping or pouch enlargement the procedure had to be repeated on 6 patients (10%). The median loss of weight in the first three months was 14.78 kg, after six months 24.14 kg and after nine months 35.1 kg. Insulin treatment for three patients suffering diabetes mellitus could be discontinued-in addition blood sugar levels in six patients normalised. Two patients with obstructive sleep-apnea syndrome no longer needed a nocturnal Nasal-Continuous-Positive-Airway-Pressure-(nCPAP-)Therapy. To provide a better quality of life to this group of patients, the gastric banding is a suitable method for carefully evaluated and followed patients. In addition improved ability to work and reduction of health care costs due to co-morbidity and joint diseases have a positive economic impact.

In 1991, gamma heavy chain disease was diagnosed in a 43-year-old female, who 3 years earlier had contracted an erosive seronegative chronic arthropathy. Her gamma heavy chain disease had a benign course, requiring no specific therapy for 5 years. In 1996, however, her lymphoproliferative disorder underwent a more malignant course, with renal and cardiac failure and increasing articular problems, requiring treatment with melphalan and prednisolone, following the protocol for myelomatosis. Laboratory studies revealed a monoclonal component in serum and urine. consistent with dimers of gamma-chains of the gamma3 subclass, but with a smaller molecular mass than normal gamma3-chains, suggesting molecular aberrations as consistently observed in this disorder. Massive localization of plasma cells and blasts with cytoplasmic or cell membrane staining for gamma3-chains, but no staining for kappa or lambda light chains, was observed by immunohistochemical studies of tissue specimens from bone marrow as well as affected synovial tissue. Large amounts of extracellular gamma3-chains were deposited in the synovial membrane. In addition, marked inflammatory changes with synovial cell hyperplasia were seen. Whether the present case represents primarily a gamma heavy chain deposition disease with reactive inflammatory changes in the joints, or another example of gamma heavy chain disease preceded by seronegative rheumatoid arthritis, remains elusive. Regardless, a possible pathogenic link between the two disease processes is an intriguing possibility.

Hereditary hemochromatosis (HHC) is one of the most common inherited disorders in the Caucasian population. Diagnosis usually made after an elevation in ferritin and serum transferrin saturation is noted, often accompanied by asymptomatic hepatomegaly. Diagnosis is confirmed by genetic testing or liver biopsy. Damage to organs is due to excessive intestinal iron, which is transported to and then deposited in the liver parenchyma, and the heart, skin, and endocrine organs, causing skin pigmentation, development of cirrhosis and hepatic carcinoma, diabetes and endocrine failure, and heart failure. Bony changes can be manifested by arthritis, often in non-weight-bearing joints. The treatment of HHC is phlebotomy, which depletes iron stores. When diagnosis is made before organ damage occurs, treatment can prevent manifestations of the disease. Skin pigmentation and some cardiac damage may reverse on depletion of iron stores, but liver and endocrine damage is rarely reversible. Arthropathy is also not reversible, and often continues to progress even with effective treatment. When hemochromatosis is diagnosed, all first degree relatives of the patient should undergo genetic testing. With early detection and treatment this can be a manageable chronic disease. If undetected, it is potentially fatal.

Hemochromatosis is a genetic disease of iron overload due to intestinal hyperabsorption of iron. It is one of the most prevalent autosomal recessive diseases in Caucasian populations. Hemochromatosis causes severe visceral and metabolic complications at adulthood, which include cirrhosis, diabetes, arthropathy and cardiac failure. A major breakthrough has been the discovery, in 1996, of the HFE gene which is strongly associated with the phenotypic expression of the disease. This discovery has, very quickly, provided a powerful genetic blood test which permits, in most cases, to establish the diagnosis in a non invasive way (i.e. without a liver biopsy). Hemochromatosis can be cured by repeated venesections provided the diagnosis has been detected sufficiently early. Moreover, an efficient preventive strategy can be applied to family members and should now be proposed to the general population. Finally, the identification of the HFE gene has paved the way for the identification of new iron overload entities.

EPIDEMIOLOGY ADN PHYSIOPATHOLOGY: Hereditary haemochromatosis is the most common genetic disease in France. Its frequency is on average 1 out of 300 French individuals. It is due to excessive dietary iron absorption, leading to accumulation of iron in the body. Mutations of the HFE1 gene are responsible for the majority of the case of haemochromatosis. FROM A CLINICAL POINT OF VIEW: The first clinical manifestations (weakness, sexual dysfunction, arthralgia, cardiac symptoms, dyspnoea on effort) can occur after the age of 30 years in men and 35 years in women (protected for longer by menstruation, pregnancy and delivery). In the absence of diagnosis, severe complications can develop during the 5th decade: nervous breakdown, arthropathy, heart failure, diabetes mellitus, cirrhosis with risk of progression towards carcinoma, responsible for handicaps and premature death. DIAGNOSTIC ELEMENTS: The diagnosis is evoked in the case of an increase in transferrine saturation (>45%), associated or not with excessive ferritin plasma levels. It is confirmed by the genetic test, showing homozygotes for the C282Y mutation or compound heterozygotes for the C282Y and H63D mutations on the HFE1 gene. RMI quantifies hepatic iron loading and generally avoids the need for a liver biopsy. The differential diagnosis must exclude secondary iron overload due to chronic transfusions in congenital or acquired blood diseases, a polymetabolic syndrome, chronic viral or alcoholic hepatic diseases and porphyria cutanea tarda. EFFICIENT TREATMENT: Today, haemochromatosis is still treated by phlebotomy. This consists in withdrawing 400 to 500ml of blood every week at the initial depletion stage and subsequently a maintenance therapy in order to maintain ferritin levels below 50 ng/ml. Paradoxically and through ignorance, hereditary haemochromatosis remains a serious disease, although its diagnosis is easy and the treatment simple and effective.

Iron overload is the main cause of morbidity and mortality especially from heart failure in patients with beta thalassemia major (TM). Successful iron chelation is therefore essential for the optimal management of TM. Although desferrioxamine (DFX) has been the major iron-chelating treatment of transfusional iron overload, compliance is a major hindrance in achieving optimal therapeutic results. The availability of oral iron chelation with deferiprone (L(1)) since 1987 is useful but showed poor efficacy when used alone as compared to DFX. We therefore decided to compare DFX alone with a prospective combined therapy with DFX and L(1) in beta thalassemia major patients with iron overload. We studied 91 patients with beta thalassemia major (mean age+/-SD, 15.02+/-5.8; range 2-30 years) attending the day care unit for regular transfusional support. They received packed red cells every 3-4 weeks to maintain pretransfusion hemoglobin concentration above 9 g/dl. They had been receiving DFX at a daily dose of 40 mg kg(-1) day(-1) by subcutaneous infusion for 8-10 h on 4-5 nights each week for the past several years. However, due to various reasons, they had developed considerable transfusional iron overload. These patients were allocated to prospectively receive additional therapy with oral iron chelator L(1) at 75 mg kg(-1) day(-1) body weight in three divided doses with food after informed consent and continued to receive treatment with DFX as per the above dosage. Of the 91 patients, six developed severe gastrointestinal (GI) upset, two agranulocytosis, two arthropathy, one persistently raised liver enzymes, two died owing to sepsis, and two received allogeneic bone marrow transplantation. Amongst the remaining 76 patients, 21 were found noncompliant (not taking DFX regularly, but taking L(1) regularly). Thus, in the 55 evaluable patients {6-48 months on combination therapy; mean [(+/-SD)22+/-12 months]}, the mean serum ferritin (+/-SD) fell dramatically from 3,088 (+/-1,299) ng/ml (DFX alone) to 2,051 (+/-935) ng/ml (DFX and L(1); p<0.001). It is interesting to note that there was also a significant improvement in the myocardial function as assessed by the ejection fraction (p<0.004) and fractional shortening (p<0.05) in those patients (n=42) who could be studied after being on combination therapy for a minimum of 1 year. The study emphasizes that beta thalassemia major patients with transfusional iron overload can be successfully treated with a combination of DFX and L(1). Our results also demonstrate a significant statistical improvement after as little as 6 months of combination therapy. Furthermore, these improvements lead to a progressive fall in the mean serum ferritin. Lastly, the study also demonstrates significant improvement in the echocardiographic parameters of myocardial performance in these patients receiving combination therapy.

Considerable knowledge has accumulated in recent decades concerning the significance of physical activity in the treatment of a number of diseases, including diseases that do not primarily manifest as disorders of the locomotive apparatus. In this review we present the evidence for prescribing exercise therapy in the treatment of metabolic syndrome-related disorders (insulin resistance, type 2 diabetes, dyslipidemia, hypertension, obesity), heart and pulmonary diseases (chronic obstructive pulmonary disease, coronary heart disease, chronic heart failure, intermittent claudication), muscle, bone and joint diseases (osteoarthritis, rheumatoid arthritis, osteoporosis, fibromyalgia, chronic fatigue syndrome) and cancer, depression, asthma and type 1 diabetes. For each disease, we review the effect of exercise therapy on disease pathogenesis, on symptoms specific to the diagnosis, on physical fitness or strength and on quality of life. The possible mechanisms of action are briefly examined and the principles for prescribing exercise therapy are discussed, focusing on the type and amount of exercise and possible contraindications.

Whipple's disease or intestinal lipodystrophy is an infection induced by Tropheryma whipplei. It is rare with an estimated incidence of 0.4 per million. Symptoms are arthropathy, weight loss, and diarrhoea, but other organs notably the central nervous system may be affected. We demonstrate a case of cardiac complications in Whipple's disease. The patient presented with endocardial infiltrations on TEE examinations and heart failure and improved after antibiotic treatment.

Topical vitamin D3 agents have emerged as important options for the treatment of psoriasis. Calcitriol, a naturally occurring and biologically active form of vitamin D3, has been developed in an ointment formulation for topical psoriasis therapy in the United States. The product has been used outside of the United States for years. Several short-term (< 6 months) clinical trials have demonstrated that calcitriol ointment 3 microg/g improves symptoms of psoriasis in participants with mild to moderate plaque psoriasis without demonstrating clinical evidence of alterations in calcium homeostasis, but little information has been available about the safety and effectiveness of continuous long-term use of calcitriol ointment. In this open-label, multicenter study, 324 participants with primarily mild to moderate chronic plaque psoriasis were treated with calcitriol ointment 3 microg/g twice daily for up to 52 weeks. A total of 136 participants completed 52 weeks of treatment. Serious adverse events (AEs) (reported by 1 participant each unless otherwise noted) included a pretibial skin ulcer (study drug was used only on the upper body), a joint disorder, metrorrhagia (2 participants), heart failure, hospitalization due to arteriosclerosis, breast carcinoma, and an infection (due to a dog bite). Clinical improvement in psoriasis symptoms was assessed by an investigator-rated global severity score (GSS) and participant-rated global assessment of improvement in psoriasis symptoms from baseline. Improvements in GSS were seen over the course of treatment. Calcitriol ointment 3 microg/g is a safe, effective, and well-tolerated option for the long-term treatment of chronic plaque psoriasis. Clinical improvement was maintained for up to 52 weeks, with no clinical effect on calcium homeostasis or other relevant laboratory test parameters.

Genetic haemochromatosis is a hereditary disease characterised by tissue iron overload. In Caucasians it is most often due to homozygous C282Y HFE gene mutation, but other genes may be involved. Without treatment by venesections, patients can develop life-threatening visceral damage such as liver cirrhosis and carcinoma, diabetes or heart failure. This treatment has been remarkably successful in preventing these complications, but patients survive with other symptoms of the disease susceptible to impair, sometimes seriously, their quality of life. This is the case of arthropathy and osteoporosis complicating haemochromatosis. In this chapter, focus has been placed on the rheumatological complications of genetic haemochromatosis.
