Enlargement of the cheeks may be due to a multitude of disorders, congenital, neoplastic, and in particular inflammatory. Congenital facial anomalies include cutaneous (and osseous) hemihypertrophy of the face and unilateral angiomatous malformations (e.g. Sturge-Weber-Krabbe Syndrome). Buccal enlargement due to dermal tumours include localized haemangiomas and lymphangiomas, lipomas and other benign connective tissue neoplasms, generalized disorders of the lymphatic or reticuloendothelial system including mycosis fungoides, reticulum cell sarcoma and other soft tissue malignancies, and cutaneous manifestations of malignant haemoblastoses, in particular chronic lymphatic leukaemia. Within the very large group of inflammatory skin swellings of the face a review is made of some bacterial pyodermias, severe forms of acne vulgaris, herpes zoster, lupus vulgaris, erysipelas, rosacea, steroid dermatitis, lupus erythematosus (discoid and systemic), toxic dermatitis, allergic eczema, urticaria, Quincke's oedema, and the Melkersson-Rosenthal syndrome. The importance of prevention and early detection of steroid-induced dermatitis is emphasized. This disorder, which is a pseudo-inflammatory disfiguring complication of prolonged topical steroid abuse, ranks in frequency with the skin problems most often seen in dermatological practice.

Alterations in the metabolism of estrogen have been implicated as an important factor in the etiology of diseases such as gynecological cancers and lupus erythematosus. The major metabolites of estradiol are hydroxylated at the C-2 or C-16 alpha position yielding products with estrogen antagonist and agonist activities, respectively. A sensitive and specific immunodiagnostic assay to determine the balance between these competing pathways might serve as a routine biomarker for management of estrogen-related diseases. We describe here the generation of high affinity, specific murine monoclonal antibodies to 2-hydroxyesterone and 16 alpha-hydroxyestrone by high efficiency fusion protocols. With these antibodies, we have developed a rapid and simple enzyme immunoassay (EIA) kit for the simultaneous quantitation of 2- and 16 alpha-hydroxyestrone in unextracted urine. Initial validation studies established that urinary metabolite 2- and 16 alpha-hydroxyestrone concentrations found by the EIA correlate well with values found by gas chromatography-mass spectroscopy. Preliminary studies with the EIA kit found total recovery of metabolites from spiked urine samples. The EIA inter- and intra-assay coefficients of variation for 2-hydroxyestrone and 16 alpha-hydroxyestrone and the ratio of 2-hydroxyesterone to 16 alpha-hydroxyestrone with the current EIA kit were consistently less than 9%. This kit, designated ESTRAMET 2/16 may provide an important new tool for research in estrogen-related diseases.

Optimal management of patients with the antiphospholipid syndrome (APS) remains a problem. There is now good evidence that those with thrombosis will be subject to recurrences and require long-term, possibly lifelong, oral anticoagulation. Steroids and immunosuppressive drugs aiming at a reduction of the antibody levels have not provided long-term benefit. Only prospective and controlled clinical trials can give a definitive answer to the optimal thrombotic prophylaxis in patients with the APS.

Therapeutic guidelines are progressively emerging in the antiphospholipid syndrome (APS). For primary APS, prevention of recurrent miscarriages is frequently achieved by a combination of heparin plus aspirin. Steroids should not be used in the absence of associated systemic lupus erythematosus. Long term warfarin aimed at an INR of 3-3.5 is effective for the secondary prevention of thrombosis. However, some doubt is raising regarding the pertinence of INR monitoring in patients with a lupus anticoagulant. Education is an important part of the management of patients with APS. Coincident risk factors for thrombosis have to be suppressed or controlled. Psychological aspects also need to be carely considered during the course of this chronic disorder.

Therapeutic guidelines are progressively emerging for the antiphospholipid syndrome (APS). In the absence of associated systemic lupus erythematosus, i.e. in primary APS, the prevention of recurrent miscarriages is frequently achieved by a combination of heparin plus aspirin. To date, there is no agreement about the type and the dose of heparin to use. Steroids should not be proposed for the prevention of miscarriages in primary APS. Long term warfarin aimed at an International Normalized Ratio (INR) of 3-3.5 is effective for secondary prevention of thrombosis. However, the appropriateness of INR for warfarin monitoring has been recently questioned in the presence of a lupus anticoagulant. Education plays an important role in the management of patients with APS. Particularly, coincident risk factors for thrombosis have to be suppressed or controlled.

Eight patients with resistant and/or relapsing nephrotic syndrome or renal insufficiency were empirically treated with mycophenolate mofetil (MMF). The underlying glomerular diseases were membranous nephropathy (N = 3), minimal change disease (n = 2), focal segmental glomerulosclerosis (n = 1), and lupus nephritis (N = 2). Treatment with MMF 0.75 to 1.0 g twice daily, either as monotherapy or in combination with low-dose steroid treatment, resulted in substantial reductions in proteinuria or stabilization of serum creatinine. In relapsing patients following withdrawal from cyclosporin A, MMF achieved suppression of proteinuria equivalent to or better than that which occurred during cyclosporin A treatment. Steroids were successfully withdrawn in each of the non-lupus patients. MMF was well tolerated with no evidence of hematologic, hepatic, or other toxicity. These clinical anecdotes demonstrate the short-term clinical efficacy of MMF treatment. In addition, they suggest that MMF may have major steroid-sparing effects and might represent an alternative to cyclosporin A in appropriate patients.

More than a decade has gone by since the detailed clinical description of the Antiphospholipid (Hughes) Syndrome. Because of the wide spectrum of manifestations, virtually any physician may encounter patients with this potentially treatable condition. Because of limited controlled, prospective data, current therapy remains empirical and directed at coagulation mechanisms, immune mechanisms, or both. There is now good evidence that patients with antiphospholipid-associated thrombosis will be subject to recurrences and require prophylactic therapy. Although most authorities agree about the efficacy of warfarin alone or warfarin plus low-dose aspirin in preventing recurrences of venous and arterial thrombosis, there is still doubt regarding the intensity and duration of warfarin therapy. Steroids and immunosuppressive drugs have not provided long-term benefit. Controlled clinical trials of the treatment of pregnant women with antiphospholipid antibody demonstrated that prednisolone is ineffective, and possibly detrimental, in treatment of recurrent pregnancy loss and that heparin plus low-dose aspirin is beneficial.

The history of antiarrhythmic therapy reveals these agents to be associated with a high incidence of toxicity. Although several agents have ocular effects, amiodarone is the most widely recognized for producing adverse effects in the eyes. Corneal microdeposits are almost ubiquitous in patients being treated with amiodarone. However, they are, for the most part, benign and produce no changes in visual acuity. Lack of microdeposits should prompt the physician to investigate whether there is a problem with drug absorption or adherence to therapy. Other effects on the eye have been reported including optic neuropathy, but no causal link has been proved with amiodarone. The population of patients treated with amiodarone often have ischemic disease and/or diabetes, which affect retinal and optic nerve health. Many antiarrhythmic agents also affect lung function. The frequent association of procainamide with a lupus-like syndrome, where half the cases develop pleural-pericardial involvement, may require discontinuation of that drug. Although beta blockers and to a lesser degree, calcium antagonists, may cause bronchospasm in some patients, this is not usually a major clinical problem. Again, it is amiodarone that has the most widespread reputation for causing pulmonary toxicity. Although infrequent (< 1% incidence), it generates the most fear as it is sometimes fatal. Because of the lack of a diagnostic "gold standard," it is often overdiagnosed, placing patients at risk from overlooked congestive heart failure and infections and from recurrent arrhythmias after drug withdrawal. Patients with pre-existing pulmonary disease appear to be more at risk. Common features include indolent onset of cough, malaise and fever associated with patchy peripheral infiltrates, and severely decreased diffusion capacity. Several cases of pulmonary toxicity have had inordinately high serum desethylamiodarone to amiodarone ratios. Most cases recover with cessation of amiodarone therapy. Steroids are commonly used, but are of unproved efficacy. In terms of its toxicity, amiodarone remains the most feared of the antiarrhythmic agents. In the future, a better understanding of its pharmacokinetics, mechanisms of toxicity, and optimal dosing regimens should provide a possibility of better strategies for avoidance, early diagnosis, and more directed therapy of toxicities associated with amiodarone.

The antiphospholipid syndrome (APS) is now emerging as an important cause of recurrent pregnancy loss. A variety of treatments, including steroids, aspirin, heparin and immunoglobulin, alone or in combination, have been assessed in experimental studies and in clinical trials. Steroids are no longer recommended as first-line therapy for patients with APS without overt lupus, because they are associated with significant foetal and maternal morbidity. Based on data from recent trials, heparin plus low-dose aspirin appears to be the regimen of choice for patients with APS who have a history of thrombosis or pregnancy losses with aspirin alone. Aspirin is safe in pregnancy. Subcutaneous heparin does not cross the placenta and therefore has no adverse effects on the foetus. For the mother, however, potential side effects of heparin treatment include bleeding, thrombocytopenia and osteoporosis. Warfarin must be avoided during the first trimester but may have a role to play subsequently in certain subsets of patients. Some studies have demonstrated that combined therapy with prednisone and aspirin, or with heparin and aspirin, may improve the outcome in women with autoimmune disorders who are undergoing in-vitro fertilization.

Infection remains a major cause of morbidity and mortality in systemic lupus erythematosus (SLE). To describe the nature and outcomes of infection and determine their associated risk factors in patients with SLE, we performed a nested case-control study at the University of Toronto Lupus Clinic, with prospective follow-up according to a standard protocol since 1970. Cases were SLE patients seen between January 1987 and January 1992 who had documented infections and controls were patients without infection from the same cohort matched for age, gender and time of visit. The type, site and outcome of infection were recorded for each case. A conditional logistic regression analysis was performed to compare factors associated with infection in cases and their controls. Ninety-three patients had 148 infection episodes; the majority were bacterial, but viral, fungal and protozoan organisms were also identified (multiple organisms in seven). Forty-eight patients required hospital admission and three patients died. Steroids at time of infection, as well as use ever, duration and dose, immunosuppressives at time of infection and use ever, active renal disease, CNS damage, SLEDAI at the time of infection, adjusted mean SLEDAI and variability measure were significantly associated with infection by univariate analysis. By multivariate analysis one factor remained statistically significant: use of steroids ever (P = 0.029). Infection carries a large burden for SLE patients. Until new medications which will control disease activity without predisposing to infection are developed, careful titration of steroids and cytotoxic drugs to control disease activity will remain crucial.
