[Description of a case of Cacchi Ricci disease associated with hyperparathyroidism in the setting of multiple endocrine disease].

The authors present a case of a 36 years old woman applied to them for a follow up of sponge kidney disease and in whom they discovered a primary hyperparathyroidism. Further investigations discovered a medullary thyroid carcinoma. So this patient present multiple endocrine neoplasia (MEN) type 2A confirmed by microscopic and genetic analysis. This observation enlarged the discussion upon the nature of the relationship between kidney disease and primary hyperparathyroidism. Elsewhere it recommended to check systematically genetic markers of MEN type 2A if there is an association with sponge kidney disease and primary hyperparathyroidism.

Metabolic and endocrine disease and arthritis.

Many metabolic and endocrine disorders have effects on the musculoskeletal system, either due to primary changes in bone and collagen or resulting in secondary arthritic and bone changes. Disorders of ossification include heterotopic ossification, diffuse idiopathic skeletal hyperostosis (DISH), and the spondyloarthropathies. The early stages of heterotopic ossification have been analyzed using immunohistochemical techniques to trace the distribution of noncollagenous proteins. Several radiographic features of DISH and ankylosing spondylitis were discussed, including rib hyperostosis and syndesmophytes. Hypertrophic osteoarthropathy with associated arthritis was described in seven patients with hepatic failure and transplantation. Remarkable improvement in arthritis followed transplantation. The inverse relationship between osteoarthritis and osteoporosis continues to be studied, and it has been hypothesized that genetics play a major role in determining the rate of bone turnover, resulting in, for example, "bone formers." Both growth hormone excess and deficiency lead to changes in the incidence of osteoarthritis. Finally, one study documented the improved outcome in joint replacements in hemophiliac patients.

Graves' disease, endocrine ophthalmopathy and smoking.

We have evaluated the association between smoking, Graves' disease and endocrine ophthalmopathy in a case-control study of 208 patients with newly diagnosed Graves' disease and carried out a retrospective survey of 72 patients treated for Graves' disease and admitted to our ward because of endocrine ophthalmopathy. In the prospective study, patients with Graves' disease smoked significantly more than their healthy controls (41% vs 30%, p < 0.01 for current smokers, odds ratio 1.6, 95% confidence interval 1.1-2.3, and p < 0.05 for patients with a history of smoking, odds ratio: 1.4, 95% confidence interval 1.0-1.9). Among the patients with endocrine ophthalmopathy at diagnosis, there were slightly more patients with a history of smoking (p < 0.05, odds ratio 2.1, 95% confidence interval 1.1-3.9), but not more current smokers when compared with the remaining group. The patients with eye problems tended to have a more active disease with higher levels of thyroxine and TSH-receptor antibodies, but no difference was seen in thyrogastric autoantibodies. No effect of smoking on thyroid hormone and autoantibody levels could be detected. In the retrospective survey we found 64%, 71% and 87% smokers among patients with moderate, severe and malignant eye disease, respectively. In summary, the results show that smoking is associated with an increased risk of contracting Graves' disease and that it enhances the severity of the eye disease in cases that develop endocrine ophthalmopathy during the course of treatment.

[Glucocorticoid therapy in endocrine disease].

Natural and synthetic glucocorticoids have been used not merely to manage chronic and acute adrenocortical insufficiency as replacement therapy, but to manage a wide variety of conditions as pharmacological agents. In endocrine disease, they are also used to achieve pharmacological effects, not necessarily related to normal physiological roles. In general, the desired effects is suppression of immune reactivity or inflammatory process. According to these effects, they are used to manage Graves' ophthalmopathy and subacute thyroiditis. They are also given to manage thyroid storm and hyperparathyroid crisis.

[Hospital overuse: evaluation and follow-up of endocrine diseases in primary health care].

On the base of a preestablished protocol, 350 patients from a hospital endocrinological clinic were evaluated to assess the possible role of primary care teams to reduce its possible massification. A comparative evaluation of the causes for consultation was carried out in those patients requiring specialized attention and those which do not need the complexities of hospital organization for their appropriate care and which should be best directed to primary care. It was concluded that there is an overload of hospital clinics, as 34.5% of patients should have been diagnosed and treated in the primary level of care. On the basis of these results, the endocrine diseases requiring primary care would basically be obesity and type II diabetes mellitus, which, in addition, are present in more than 50% of the patients on care.

[Relationship between corticotropin and arginine vasopressin in endocrine diseases].

VASOPRESSIN: The action of vasopressin (AVP) is not limited to regulating water excretion but also plays an essential role in regulating the corticotropic axis during stress. PHYSIOLOGY: Vasopressin is synthesized in the hypothalamus and stored in the posterior pituitary. It acts on 3 types of receptors (RV). RV1a are vascular receptors mediating the vasoconstrictor and glycogenolytic effects of the hormone. Anterior pituitary RV1b or V3 mediate stimulating effects on the corticotropic axis. Renal RV2 regulate water and urea excretion. Hypothetical extrarenal RV2 would be responsible for the vasodilator and procoagulant effects of the hormone. MODIFICATIONS IN ENDOCRINE DISEASES: Pituitary or adrenal hypocorticism syndromes include hyponatremia with secondary plasma hypoosmolality and reduced glomerular filtration due to the direct effect of glucocorticoids and also the effect of vasopressinism. Certain endogenous hypercorticisms appear to be related to an overexpression of RV: in ACTH-independent Cushingís syndrome, adrenal overexpression of eutopic RV1a, and in ACTH-dependent Cushingís syndrome, pituitary overexpression of eutopic RV1b or ectopic RV2. In addition, inappropriate secretion of antidiuretic hormone is frequent after transphenoidal surgery, particularly for corticotropic adenomas. DYNAMIC TESTS: The physiological response of ACTH and also AVP to corticotropin releasing hormone (CRH) in the petrous sinus, the unusual responses of certain corticotropic tumors to dDAVP, or certain forms of ACTH-independent hypercortisolism to lysine vasopressin (LVP) suggest excessive or ectopic expression of RV in corticotropic or adrenal cells: tumorgenesis of these cells could also depend, at least partially, on AVP.

Frequency of diabetes and thyroid autoantibodies in patients with autoimmune endocrine disease from Cameroon.

BACKGROUND: Diabetes is a major cause of morbidity and mortality in both industrialized and developing countries. In Africa, there are little data on the prevalence and immunological features of patients with autoimmune endocrine diseases. AIM OF THE STUDY: The present hospital-based study was carried out to evaluate disease-associated autoantibodies in both type 1 diabetes and thyrotoxicosis attending the Central Hospital of Yaoundee in Cameroon. PATIENTS AND METHODS: Samples were collected from a total of 101 subjects, 47 of whom clinically had established type 1 diabetes (mean age 30.1 years +/- 7.6, mean disease duration 3.3 years), 18 had thyrotoxicosis (mean age 32.7 years +/- 7.6, mean disease duration 6.3 years +/- 2.8) and 36 normal subjects (mean age 26 years +/- 4.5). All subjects were tested for diabetes-associated glutamic acid decarboxylase (GAD) and tyrosine phosphatase (IA2) autoantibodies using antigen-specific radioimmunoassay as well as thyroiditis-associated thyroglobulin (Tg) and thyroid peroxidase (TPO) autoantibodies using commercially available kits. RESULTS: Of 47 patients with type 1 diabetes, 16 (34%) had GAD autoantibodies (Abs), 3 (6.4%) had IA2 Abs, and 2 (4.3%) had TPO Abs. Of 18 patients with thyrotoxicosis 4 (22.2%) had GAD Abs, 5 (27.8%) showed IA2 Abs, while 8 patients (44.4%) were TPO Abs positive. No patients in either group had Tg Abs. Among normal subjects, 2 (5.6%) showed GAD Abs, and one of these was also IA2 Abs positive, but none had thyroid autoantibodies. CONCLUSION: Adult-onset type 1 diabetic patients some years post-diagnosis from central Africa show GAD, IA2 or TPO Abs; and surprisingly, patients with thyrotoxicosis had a similar frequency of diabetes-associated autoantibodies. We conclude that, despite a different genetic and environmental background to European populations, islet cell autoimmunity is common in autoimmune endocrine patients in central Africa.

Update on drugs used to treat endocrine diseases in small animals.

Drug therapy for the endocrine system is implemented to replace a hormone deficiency or to prevent or reduce the formation or effects of excess hormone. Treatment of endocrine disorders covers diseases of the pituitary, adrenal, parathyroid, and thyroid glands as well as the endocrine pancreas. This article focuses on new therapies currently available for specific diseases. Administration of trilostane for treatment of hyperadrenocorticism and use of insulin glargine, protamine zinc insulin (PZI), and porcine Lente insulin for diabetes mellitus are discussed. In addition, transdermal methimazole therapy for treatment of feline hyperthyroidism and administration of progestins for pituitary dwarfism are considered.

[Endocrine diseases and aging].

Age dependent perturbations to endocrine systems are overviewed and the interpretation of the results of endocrinological tests for clinical decision are discussed referring to thyroid diseases as an example. The endocrine functions that are essential to life, such as adrenal and thyroid functions, show minimal change by aging. Their basal levels alter little, although production and degradation of hormones decrease. Some part of elderly persons show lower levels of triiodothyronine, which may, however, reflect deterioration of their physical condition and should not be overlooked as an age dependent change. Some endocrine function, such as gonadal function and calcium metabolism obviously reveal age dependent physiological change and their reference ranges for elderly persons are set separately. Thus, reference levels and clinical decision for endocrinological tests should be dependent on the properties of individual endocrine system.
