Niflumic acid-induced skeletal fluorosis: iatrogenic disease or therapeutic perspective for osteoporosis?

A case of skeletal fluorosis induced by prolonged treatment with niflumic acid, a fast-acting non-steroid antiinflammatory agent, is reported in a 35-year-old woman suffering from rheumatoid arthritis and treated, in addition, with corticosteroids. The case report discussed is, to our knowledge, the third of its kind regarding bone fluorosis resulting from use of this nicotinic derivative. This clinically asymptomatic case of skeletal fluorosis was discovered, as in the 2 previously reported cases, by the examination of bone X-ray (performed as part of the routine work-up for rheumatoid arthritis) which showed evident osteosclerosis. Quantitative histologic study of iliac crest biopsy revealed marked increase in trabecular bone volume and osteoid volume, suggestive of fluorosis. Abnormally high urine and bone fluoride confirmed the diagnosis. After ruling out a hydrotelluric source of fluorine, the patient's fluorosis was linked to chronic use of niflumic acid, following the publication in 1978 of the 2 previously reported cases affected by this drug. The fluorine contained in niflumic acid induced a marked densification of trabecular bone in all 3 cases. Long-term clinical and pharmacokinetic studies will be required to determine whether or not niflumic acid can be employed in the prevention or treatment of both of apparently idiopathic osteoporosis or corticosteroid-induced osteoporosis.

Calcium channel blocker-induced gingival hyperplasia: case report and review of this iatrogenic disease.

Gingival hyperplasia is a common disorder associated with phenytoin and cyclosporine therapy. However, induction of this condition by calcium channel blockers is less well known. Inflammation of the gingival tissue from bacterial plaque and the subsequent development of gingival crevicular fluid may allow sequestration of the calcium channel blocker, thus predisposing the tissue to a localized toxic effect and the development of gingival hyperplasia. Calcium channel blockers have cellular effects similar to those of phenytoin and cyclosporine, including the production of a localized folic acid deficiency. All of the available calcium channel blockers have been reported to cause gingival hyperplasia. Treatment options include meticulous plaque control, and in severe cases, gingivectomy. Gingival hyperplasia can be prevented with meticulous plaque control or avoidance of the offending medication.

[An overview of ovarian hyperstimulation syndrome: a reproductive medicine-iatrogenic disease picture with internal medicine consequences].

The ovarian hyperstimulation syndrome is a complication of the controlled ovarian hyperstimulation in assisted reproduction procedures. It has become more widespread, since the techniques of ovarian hyperstimulation has become more frequent. The potentially life-threatening complication of this condition is a hemoconcentration with subsequent thrombo-embolic complications and death. In this article the pathophysiology, prevention strategies, treatment guidelines and more theoretical approaches for the therapy are reviewed and discussed.

[Hyperthyroidism induced by iodine in an apparently normal thyroid gland. A new iatrogenic disease].

Iodine-induced thyrotoxicosis was reported to occur in patients with previously altered thyroid gland. Evidence is presented here from 23 cases that iodine-induced thyrotoxicosis may also occur in patients with no prior thyroid desorder and is characterized by: a) an almost undetectable 131I uptake, wich can be activated by TSH; b) a spontaneous improvement within a few weeks or months after withdrawing the high intake of iodine; c) the absence of any detectable thyroid abnormality after recovery.

[Iatrogenic sinus node disease and iatrogenic AV block].

The appearance of long lasting bradycardia due to damage of the sinus node (iatrogen sick sinus syndrome; or the atrioventricular conduction system, iatrogen AV block) is not a rare event after open heart surgery. In the course of 5093 heart operations the development of iatrogen sick sinus syndrome was observed in 234 patients (4.6%) and iatrogen AV block in 91 cases (1.8%). The incidence rate of iatrogen sick sinus syndrome or iatrogen AV block was quite divergent depending mostly on the type of operation. Comparing the data of our earlier (1977-1982) and later (1983-1991) cardiac surgical interventions, the prevalence of iatrogen sinus node disease and iatrogen AV block seems to decrease, mainly due to the progress in techniques of cardiac surgery. With the appearance of iatrogen sick sinus syndrome or AV block, urgent temporary pacing is indicated to prevent the deleterious hemodynamic effect of bradycardia. In the cases of persistent iatrogen sick sinus syndrome and iatrogen AV block, permanent pacemaker implantation is needed. It is remarkable that although the incidence rate of iatrogen sick sinus syndrome is greater than that of iatrogen AV block, in iatrogen sick sinus syndrome the regression is quite frequent, while in iatrogen AV block the 2nd or 3rd degree AV block is usually permanent. We performed pacemaker implantation in 56 cases of iatrogen sick sinus syndrome (24%) and in 57 patients of iatrogen AV block (63%). With pacemaker therapy the outcome of iatrogen sick sinus syndrome and iatrogen AV block is very favourable.

Capsule endoscopy: current indications and future prospects.

Capsule endoscopy represents a significant advance in the investigation of small bowel diseases and the beginning of wireless endoscopic imaging. Capsule endoscopy involves swallowing a video capsule endoscope, which is painless and relatively safe. Its use has been established for suspected small bowel bleeding, and the role of capsule endoscopy in the investigation of inflammatory bowel disease, iatrogenic disease, polyposis syndromes and coeliac disease is evolving. It is likely that in many instances it will become the next test after standard endoscopic evaluation. Early data suggest that capsule endoscopy improves outcome in patients with suspected small bowel bleeding, but more data are required on outcomes for the other indications.

Iatrogenic renal disease.

We studied iatrogenic problems in nephrology by classifying all patients for nephrology consultation into nine presenting syndromes and seven etiologic groups. One hundred (2.2%) of all admissions were seen in nephrology consultation. Acute renal failure was the most common presenting syndrome, accounting for 59% of the consultations. Forty-one of the 100 consultations (1% of all admissions) had a renewal syndrome of iatrogenic origin. Of these 41 patients, 38 had acute renal failure and three had fluid and electrolyte problems. Twenty of the 41 patients had drug-induced problems. Eighteen of these patients were dehydrated, and in three patients, acute renal failure occurred after surgery. Of the 20 patients with iatrogenic renal problems caused by drugs, seven problems were antibiotic related, five were due to diuretics, four were due to nonsteroidal anti-inflammatory drugs, three were due to angiotensin-converting enzyme inhibitors, and one was from the use of contrast medium. The 41 patients with iatrogenic-related renal disease were older than the other 59 patients (61.8 vs 49.3 years). Iatrogenic renal disease developed in 1% of all patients admitted to a tertiary care hospital, and 12% of these patients died. The most common renal syndrome is acute renal failure, most often caused by nephrotoxic drugs. The incidence can probably be decreased by better monitoring of body weight and fluid balance to prevent dehydration and by the avoidance of nephrotoxic drugs.
