Since about 1950 especially, dermatologists world-wide have been utilizing the positive side-effects, discovered by chance, of all groups of antibiotic and antimicrobial drugs. These drugs are used to treat certain non-microbially induced dermatoses, without any knowledge of the mechanisms involved. A short history is given and the most important drugs and the indications for their use are described. The following drugs are undoubtedly effective and sometimes even the therapy of choice: tetracyclines in acne vulgaris and rosacea (including rosacea keratitis); penicillin G in acrodermatitis atrophicans and cold urticaria; dapsone in dermatitis herpetiformis and - as a powerful adjuvant - in acne vulgaris and rosacea. Before the discovery of the socalled immunodepressive drugs, tetracycline was the only alternative to - or at least a highly effective adjuvant of - cortisone in dermatomyositis and chloroquine in localised and systemic lupus erythematosus. Finally, clioquinole was life-saving in acrodermatitis continua in children until this condition was recently identified as a zinc-deficiency syndrome. Therapeutical mechanisms have been found only in the case of acne, rosacea and dermatitis herpetiformis. In most other diseases the nature of the therapeutical effectiveness of antibiotic and antimicrobial drugs still remains a mystery.

A patient with systemic lupus erythematosus and a three-month history of bilateral follicular conjunctivitis had both a superficial and deep culture-negative keratitis. Although SLE interstitial keratitis is uncommon, it must be recognized as a definite clinical entity. Its prompt recognition and treatment with corticosteroids may quickly bring about improvement, whereas if it is unrecognized, corneal scarring and loss of vision may follow.

Of 32 patients (19 females and 13 males, ranging in age from 2 to 44 years), nine had ocular problems related to neutrophil dysfunction. Four patients had blepharokeratoconjunctivitis and pannus formation. In one of these, severe visual loss secondary to corneal thinning and scarring occurred. Five patients had inactive chorioretinal scars without visual loss. Although some of the other 23 patients had minor ocular abnormalities, we could not demonstrate that they were related to the neutrophil dysfunction. However, none of the control subjects (20 patients with systemic lupus erythematosus and 20 randomly selected eye clinic patients) had lesions resembling those of the patients with neutrophil dysfunction. Fisher's exact test (one-tailed) gave the following values: P less than .03 for keratitis; P less than .01 for chorioretinal scars; and P less than .001 for keratitis and chorioretinal scars. Abnormal neutrophil function probably interferes with the control of normal eyelid flora and predisposes the eye to the development of marginal keratitis. Eyelid hygiene and topical administration of antibiotics and corticosteroids during inflammatory episodes may prevent the progression of corneal vascularization. The chorioretinal scars do not appear to be progressive.

Sensorineural hearing loss may occur in SLE, but aortic insufficiency has been very rarely reported. We are describing two patients with well-established SLE who developed bilateral hearing loss and aortic insufficiency, associated with serological evidence of active lupus. Neither patient had evidence of keratitis, and thus did not satisfy criteria for Cogan's syndrome. The aortic insufficiency in one patient stabilized after treatment with high doses of steroids while in the second patient, who refused medical treatment, it progressed requiring surgical valve replacement. Our observations suggest that the aortic valve and the inner ear may share some antigenic crossreactivity not shared by the cornea. In SLE patients, with sensorineural hearing loss, echocardiography should be performed looking for evidence of aortic insufficiency, which may be steroid responsive.

We report the optical and ultrasonic biomicroscopy and confocal microscopy findings in bilateral stromal keratitis (keratoendotheliitis), a rare ocular manifestation of systemic lupus erythematosus (SLE). Examination revealed deposits with polyrefringent crystals. Topical corticosteroid produced regression of the corneal edema, but there was an increase in corneal opacity. Ultrasound biomicroscopy images confirmed the deep location of the corneal opacities, and confocal microscopy showed a disruption of the corneal stroma and crystal-like bodies.

Presenilin (PS1) and (PS2) are the centers of gamma-secretase that release Abeta from APP in Alzheimer's disease (AD). They cleave signaling proteins like Notch and downregulate beta-catenin to modulate Wnt signaling. Inactivation of PS1 or PS1 and PS2 causes a prenatally lethal 'Notch phenotype,' which has hampered investigation of PS function in adulthood seriously. We have thus turned towards PS1+/-PS2-/- mice which carry the most severe reduction of PS alleles compatible with survival, to analyze the consequences of impaired PS function especially in adulthood. In these 'partial deficient' mice, PS1 protein concentration is considerably lowered, functionally reflected by reduced gamma-secretase activity and impaired beta-catenin downregulation. Their phenotype is normal up to approximately 6 months, when the majority of the mice develop an autoimmune disease characterized by dermatitis, glomerulonephritis, keratitis and vasculitis, as seen in human systemic lupus erythematosus. Besides B-cell dominated infiltrates, we observe a hypergammaglobulinemia with immune complex deposits in several tissues, high-titer nuclear autoantibodies and an increased CD4+/CD8+ ratio. The mice further develop a benign skin hyperplasia similar to human seborrheic keratosis as opposed to malignant keratocarcinomata observed in skin-specific PS1 'full' knockouts. A partial reduction of PS function in PS1+/-PS2-/- mice causes a novel phenotype in adulthood unrelated to the developmental defects of full knockouts. As PS1+/-PS2+/- mice remain healthy, this points towards a sharply defined minimum of PS function. Skin and immune system appear to be especially sensitive targets of impaired PS function and may need careful monitoring if gamma-secretase inhibitors are envisaged for treating AD.

Rapidly growing mycobacteria (RGM) have emerged as important human pathogens that can cause a variety of diseases. Thirty isolates of the pathogenic RGM were recovered from patients who attended King Chulalongkorn Memorial Hospital during 1997 and 2003. There were 16 isolates of Mycobacterium chelonae, ten isolates of M. fortuitum and four isolates of M. abscessus. Clinical data was available in only nine patients (five males and four females) including six M. chelonae, two M. abscessus, and one M. fortuitum. The mean age was 37 years (range: 13-62 years). The associated conditions were present in five patients including two diabetes, one HIV infection, one pregnancy, one SLE and one chronic renal failure. A wide spectrum of clinical features was observed. These included two chronic pulmonary infections, two post-traumatic wound infections, two disseminated infections, one lymphadenitis, one keratitis and respiratory colonization. AFB staining was positive in six patients (66.67%). The MIC of one M. chelonae and one M. abscessus were determined by Epsilon test. For M. chelonae, the MIC of clarithromycin, amikacin, ciprofloxacin, sulfamethoxazole and imipenem were 0.25, 2.0, 1.00, > 64, and 0.54 microg/ml, respectively. For M. abscessus, the MIC of clarithromycin, amikacin, ciprofloxacin, tetracycline and sulfamethoxazole were 0.016, 0.016, 0.038, > 16 and 0.002 microg/ml, respectively. Six of eight patients (75%) were initially treated with four first-line antituberculous drugs (isoniazid, rifampicin, pyrazinamide and ethambutol) before obtaining the culture result. Of these, three patients with pulmonary and disseminated infections improved after a prolonged course of these combinations. The patients improved after switching to specific anti-RGM antibiotics. One patient died after 10 months of therapy of four anti-tuberculous drugs. One patient with post-traumatic wound infection was cured with surgical debridement and dicloxacillin. One patient improved after treatment as acute bronchitis with oral amoxicillin. An extensive review of the literature of RGM infections in Thailand is also presented.

Systemic lupus erythematosus (SLE) is a chronic, immunologically mediated inflammatory connective tissue disorder with manifestations including various body organs (joints, pleura, pericardium, kidneys, brain, skin), caused by accumulation of immune complexes. According to epidemiological data SLE affects 0.12% of the population worldwide, while in Poland the number of reported cases is c. 60 000 - 80 000. SLE may also involve the eye. Anterior segment findings include keratoconjunctivitis sicca, keratitis and scleritis. Retinal manifestations of SLE are cotton wool spots, hemorrhage and vasculitis. The ARA (American Rheumatism Association), criteria are used in establishing the diagnosis of SLE. Although the ocular symptoms are not included in the ARA criteria, they may be initial findings and precede other manifestations of SLE.
