Oral candidiasis in patients with psoriasis: correlation of oral examination and cytopathological evaluation with psoriasis disease severity and treatment.

BACKGROUND Infections are known to trigger and exacerbate psoriasis. Although oral candidiasis is often clinically diagnosed, it is not always confirmed by laboratory tests such as oral cytopathology. OBJECTIVES The aims of this study were to determine the prevalence of oral candidiasis in patients with psoriasis through clinical and cytopathological diagnosis and to investigate the association between oral candidiasis and psoriasis with regards to the severity of the clinical presentation and the type of treatment for psoriasis. METHODS A total of 140 patients with psoriasis and 140 healthy control subjects received an oral examination. Scrapings of the tongue were also obtained for a cytopathological examination. RESULTS The oral examination and the results of the cytopathological smear revealed 37 (26%) cases of candidiasis in the patients with psoriasis and no cases of candidiasis in the healthy control subjects. There was no correlation between the type of psoriasis treatment and the presence of oral candidiasis (P = .616). There was a statistically significant association (P = .033) between the clinical severity of psoriasis and the presence of Candida. LIMITATIONS This study was limited by the small number of subjects and the lack of follow-up to determine the development of psoriasis after treatment for oral candidiasis. CONCLUSIONS The presence of oral candidiasis is higher in patients with psoriasis and it is associated with disease severity. This increased presence of oral candidiasis was apparent despite any type of treatment for the psoriasis. Cytopathology to rule out oral candidiasis should be used in the routine medical workup of patients with psoriasis.

Pyoderma gangrenosum following isotretinoin therapy for acne nodulocystic

A 19‐year‐old man with nodulocystic acne on baseline was treated with isotretinoin therapy. After 1 month on the medication, he developed pyoderma gangrenosum on his pubis area, arms and legs, and pathergy on a puncture site. Possible underlying diseases were excluded. The patient was started on steroids (prednisone 1 mg/kg/d) and isotretinoin therapy was withdrawn. Later the prednisone was tappered and dapsone 100 mg/daily was initiated. After 10 months of follow‐up all lesions had healed and no underlying diseases developed.

Geographic Tongue and Fissured Tongue in 348 Patients with Psoriasis: Correlation with Disease Severity

Geographic tongue (GT) and fissured tongue (FT) are the more frequent oral lesions in patients with psoriasis. The aims of this study were to compare the prevalence of GT/FT between psoriasis group (PG) and healthy controls (HC) and investigate the correlation between GT/FT and psoriasis severity using the PASI and age of psoriasis onset. Three hundred and forty-eight PG and 348 HC were selected. According to the age of psoriasis onset, the individuals were classified as having early psoriasis and late psoriasis. The severity of vulgaris psoriasis was determined according to PASI. A follow-up was conducted in patients with psoriasis vulgaris (PV) with GT to evaluate the progression of oral and cutaneous lesions. The FT and GT were more frequent in PG than in HC. The incidence of GT was higher in patients with early psoriasis and that of FT in late-psoriasis. There is association between psoriasis intensity and GT; and a higher monthly decrease of PASI score in patients without GT. The presence of GT and FT is higher in PG than in the HC. GT is associated with disease severity and may be a marker of the psoriasis severity.

Acrodermatitis enteropathica in a full-term breast-fed infant: case report and literature review

A male full‐term infant, who had been exclusively breast‐fed since birth, at 2 months of age developed an erythematous, scaling eruption involving the face (in a periorificial distribution, i.e. mouth, nose, ears, and eyes), hands, and feet, which did not respond to treatment with topical corticosteroids and oral antimicrobials. He was first seen at our institution at 5 months of age ( Figs 1 and 2 ). He had been irritable for the last 2 weeks, but had no diarrhea, alopecia, or anogenital lesions. A clinical diagnosis of acrodermatitis enteropathica was confirmed with a serum zinc level of 41.2 µg/dL (normal, 70–120 µg/dL). His mother had low–normal serum (70.5 µg/dL; normal, 70–120 µg/dL) and normal milk (0.43 µg/mL; normal, 0.2–0.72 µg/mL) zinc concentrations. Within 7 days of starting therapy with zinc sulfate, 10 mg/kg/day, all cutaneous lesions had resolved ( Fig. 3 ).

Pomada de tacrolimo 0,1% no tratamento de vitiligo: série de casos

Vitiligo is a dermatosis of difficult treatment and significant psychosocial impact. The objective of this study was to evaluate the response to tacrolimus 0,1% ointment for vitiligo treatment. Ten patients took part in the present study: six patients with lesions on the cephalic and cervical regions had more than 75% of repigmentation. As for extremities and trunk results varied from good to excellent in 27% of the cases. The association with other therapeutic options could possibly increase the efficacy of the treatment.

Investigation of the clinical features of geographic tongue: unveiling its relationship with oral psoriasis

Few studies have examined the clinical features of geographic tongue (GT), an inflammatory lesion, making diagnosis and the investigation of oral psoriasis difficult.

Ulcerations due to methotrexate toxicity in a psoriasis patient

Methotrexate is one of the most used drugs in the treatment of psoriasis with indication of systemic therapy. Cutaneous and mucous side effects are described by pharmacological characteristics of the drug itself or due to overdose. We report the case of a patient with ulcerations in oral mucosa and psoriatic plaques after incorrect use of Methotrexate. Prescribed in a weekly dose, it was used continuously for 10 days and without simultaneous intake of folic acid. It is important to ensure correct comprehension of the prescription.

Two cases of renal cell cancer during immunobiologic therapy for psoriasis

Immunobiologic therapy is indicated for severe forms of psoriasis, resistant to conventional therapy. There is growing concern about their safety profile and possible association with cancer development. This article documents two cases of renal cell cancer during treatment with biologic therapy, reviewing what is described in the literature . The risk of solid tumors as a complication of using TNF-alpha inhibitors is controversial. No conclusion can be drawn from the data in the literature, however, we believe that special attention should be given to those with known risk factors for a specific neoplasm.
