A technique for the biopsy of oral lesions.

BACKGROUND: Biopsy of mucosal lesions can be carried out by means of several methods. OBJECTIVE: To describe a combination technique for the biopsy of mucosal lesions. METHODS: The combined effect of a chalazion forceps with a 4-mm punch allows the physicians to work on a stabilized, bloodless, and therefore simplified field. RESULTS: A preliminary suture with a 4-0 catgut chromic is the key step in assuring a safe post-operative hemostasis. CONCLUSION: This technique allows us to perform accurate and safe oral mucosal biopsies without any major side effects.

Echographic diagnosis of pretibial myxedema in patients with autoimmune thyroid disease.

In the present study we have evaluated the use of pretibial ultrasound for the diagnosis of pretibial myxedema (PTM). We studied 76 patients, 58 with Graves' disease, 13 with Hashimoto's thyroiditis and five with idiopathic hypothyroidism. Thirty-two normal subjects were also studied as controls. Sixty-four patients had associated ophthalmopathy. The ultrasound scanner was equipped with 10- and 13-MHz probes. Punch biopsies were carried out in 11 patients and tissue sections examined on a light microscope. On clinical examination 21 patients (28%) had suspected PTM. By ultrasound, we measured the thickness of dermis and subcutaneous tissue (D1) and that including only deeper dermis (D2) in normal subjects to define the echographic parameters of normal pretibial skin. We then found increased skin thickness in 25 patients (33%), with mean D1 and D2 values significantly higher than those measured in controls (p < 0.00001). The echographic study was positive in 20 patients with ophthalmopathy (31%). Ultrasound showed increased skin thickness in 16 of 21 patients (76%) with clinically suspected PTM. Histopathological findings confirmed the presence of PTM in all the patients who underwent pretibial skin biopsy. We believe that the measurement of pretibial skin thickness by ultrasound may be useful for revealing the presence of PTM.

Sporothricoid mycobacterial infection. A case report.

A case of bilateral, symmetric, sporothricoid granulomas involving the dorsa of fingers and wrists is reported. The culture-proved Mycobacterium marinum skin infection was acquired by a fish-fancier while clearing his aquarium with bare hands. The patient suffered from chronic hand eczema. Treatment with co-trimoxazole was successful.

[Diabetic bullosis. A case report].

Bullosis diabeticorum is a very rare complication of diabetes; few more than fifty cases have been reported in literature. We report on an 80-year-old man with non-insulin dependent diabetes mellitus who showed bullosis diabeticorum relapsing at the leg. We describe the cutaneous feature and the procedure carried out. We analyze the different etio-pathogenetic hypothesis and differential diagnosis, that is always by exclusion.

Evaluation of Western immunoblotting technique in the serological diagnosis of human syphilitic infections.

Purified human syphilitic antibodies against both 15.5 Kd and 45 Kd treponemal antigens appear T. pallidum specific and do not cross react with antigens possessed by other treponemes (T. phagedenis, T. hyodysenteriae and a human intestinal treponeme). By using Western immunoblotting technique, 107 out of 110 syphilitic patients and 291 out of 294 subjects with serologically positive diagnostic tests for syphilis were found to have in their sera antibodies against a 15.5 Kd specific antigen of T. pallidum. These antibodies were present in 100% of the patient with secondary or early latent syphilis, both untreated and treated, in 98.24% of those with late latent treated syphilis and in 100% of patients with neurosyphilis. On the contrary, they were absent in 47 patients with false positive reactions for syphilis and in 121 healthy blood donors. For these reasons, the demonstration of these kind of antibodies in a patient's serum can be considered of high value in differentiating syphilitic patients from non infected individuals.

Systemic administration of antibiotics in the management of venous ulcers. A randomized clinical trial.

Forty-seven patients with chronic venous leg ulcers were included in a randomized clinical trial to evaluate the efficacy of systemically administered antibiotics in healing with condition. One group was treated by means of elastic support bandages only, whereas the other one received the same local treatment plus systemic antibiotics. No statistically relevant difference was noted between the two groups in healing rates of ulcers or in changes of the microbiologic flora. The results of our study do not support the routine administration of systemic antibiotics in the management of chronic venous leg ulcers.

Isolation of Chlamydia trachomatis from the prostatic cells in patients affected by nonacute abacterial prostatitis.

To assess the presence of Chlamydia trachomatis in nonacute abacterial prostatitis 30 patients with urethral cultures positive for Chlamydia trachomatis underwent microbiological studies, including cultures of transrectal aspiration biopsies of the prostate. Chlamydia trachomatis was isolated from 10 of the prostatic specimens (33 per cent). In 3 cases a nonspecific cytopathogenic effect caused the destruction of the tissue cultures. Our findings demonstrate that Chlamydia trachomatis may cause ascending infections of the prostate and that this microorganism may have an etiological role in the pathogenesis of nonacute abacterial prostatitis.

Cutaneous hyperpigmentation induced by amiodarone hydrochloride.

Amiodarone (Cordarone) is an iodinated compound widely used in the treatment of cardiac arrhythmias for more than a decade. A patient who developed a persistent blue-gray skin pigmentation of the light-exposed areas following long-term amiodarone hydrochloride administration is reported. The cutaneous signs and the ultrastructural findings are described. This rare iatrogenic hyperpigmentation is peculiarly due to lipofuscin and not melanin deposits. Its pathogenesis may be related to the basic action of the drug on the lysosome and to the extra phototoxic-induced lysosomal damage, which accounts for the specific location of the hyperpigmentation over the light-exposed areas.

Multiple persistent keratoacanthomas: treatment with oral etretinate.

Multiple keratoacanthomas (KAs) of the Ferguson-Smith type represent a rare and distinctive disease for which treatment is difficult and often unrewarding. Two patients with multiple KAs of this variety, who were successfully treated with oral etretinate, are described. Our cases support the conclusion that oral retinoids have to be added to the treatment modalities for this entity. Use of oral retinoids is particularly recommended when the number of lesions is very high or when the development of new lesions is severely disabling.

Sweet's syndrome in chronic lymphocytic leukemia.

We describe the case of a man, previously affected by B-CLL, who developed Sweet's syndrome four months later the previous diagnosis. Sweet's syndrome was diagnosed by cutaneous biopsy. Neither infections nor drugs administration were demonstrated, in order to explain beginning of Sweet's syndrome. Altered immune responsiveness, as seen in B-CLL, could cause Sweet's syndrome.
