Associated oral manifestations with HIV southeastern Brazilian patients on antiretroviral therapy.

OBJECTIVES: This study aimed to assess the prevalence of oral lesions in patients living with HIV infection and their association with CD4 count, viral load, and antiretroviral therapy in patients with HIV. METHODS: A cross-sectional study was conducted on a sample of 161 patients attending the… All the patients were examined for their oral lesions, current CD4 counts, type, and duration of the therapy. Data analyses were carried out using Chi-Square, Student T/Mann-Whitney, and logistic regression tests. RESULTS: Oral lesions were observed in 58.39% of patients with HIV. Periodontal disease with 78 (48.45%) or without mobility 79 (49.07%) was observed more frequently, followed by hyperpigmentation of oral mucosa 23 (14.29%), Linear Gingival Erythema (LGE) 15 (9.32%), candidiasis pseudomembranous 14 (8.70%). Oral Hairy Leukoplakia (OHL) was observed only in 3 (1.86%). A relationship between periodontal disease with dental mobility and smoking was found (p=0.04), as well duration of treatment (p=1.53e-3) and age (p=0.02). Hyperpigmentation was related to race (p=0.01) and smoking (p=1.30e-6). CD4 count, CD4:CD8 ratio, viral load, or type of treatment were not associated with oral lesions. Logistic regression showed that the duration of treatment has a protective effect on the periodontal disease with dental mobility (OR = 0.28 [-2.27 to -0.25]; p-value=0.03), independent of age or smoking. To hyperpigmentation, the best model included smoking (OR=8.47 [1.18-3.10], p= 1.31e-5), without race or type and duration of treatment. CONCLUSION: Among HIV patients undergoing antiretroviral treatment, oral lesions can be observed, predominantly periodontal disease. Pseudomembranous candidiasis and oral hairy leukoplakia were also observed. No relationship was found between associated oral manifestations in HIV patients and the start of the treatment, TCD4+ and TCD8+ cell count, TCD4:TCD8 ratio, or viral load. The data indicate that there is a protective effect of duration of treatment with relation to periodontal disease with mobility and that hyperpigmentation seems to be more related to smoking than type and duration of treatment.

Oral hyperpigmentation as an initial clinical aspect of hand foot syndrome.

Hand-foot syndrome (HFS) is a common adverse effect of anticancer therapy. It is known to cause dermatological symptoms including acral erythema and dysesthesia of the palms and soles of the feet, swelling, pain, itching, and scaling. Some drugs, like capecitabine, are known to trigger this condition. However, pigmentation of the oral mucosa is a rare adverse effect. This study aims to report a case of oral mucosa hyperpigmentation caused by capecitabine therapy before the clinical diagnosis of HFS. A 58-year-old female, diagnosed with invasive breast duct carcinoma, had the central nervous system, liver, skin, and lung metastasis, using capecitabine every day for 14 cycles. Oral examination revealed multifocal black macules on the hard palate, bilateral buccal mucosa, gingival mucosa, and dorsum of the tongue. The clinical hypothesis was oral mucosa hyperpigmentation by capecitabine use and only periodic follow-up was necessary. Hyperpigmentation of oral mucosa by capecitabine is a rare consequence of neoplastic therapy and your association with HFS is unclear, and poorly reported. The report of these events is important to alert oncology health teams about the individual tolerance to capecitabine therapy.

[Primary pigmented nodular adrenocortical disease as cause of Cushing's syndrome associated with Carney complex]. / Primarna pigmentna nodularna adrenokortikalna bolest kao uzrok Cushingova sindroma u sklopu Carneyeva kompleksa.

We report a 11-year-old girl and two 14-year-old boys with Cushing's syndrome due to primary pigmented nodular adrenocortical disease (PPNAD). In these patients, hypercortisolism is a consequence of autonomous cortisol secretion from adrenal glands and is ACTH-independent. Besides PPNAD, the girl had lentigines, spotty pigmentation on her bucal mucosa and lips and she also had schwannoma. One of the reported boys had prolactinoma. Considering this, those two patients fulfill the criteria for Carney complex which is a type of multiple endocrine neoplasia syndromes inherited in an autosomal dominant trait. The other boy had PPNAD but no other obvious signs of Carney complex were noticed. Family study didn't reveal any clinical or laboratory signs of Carney complex in our patients' first relatives. All of our patients underwent bilateral adrenalectomy (in one of the boys laparoscopic surgery was performed). Glucocorticoid and mineralocorticoid substitution has been started. Adrenal glands were macroscopically normal but pathohistological analysis confirmed the diagnosis of PPNAD.

Repigmentation of gray hair in lesions of annular elastolytic giant cell granuloma.

Hair pigmentation is a complex phenomenon that involves many hormones, neurotransmitters, cytokines, growth factors, eicosanoids, cyclic nucleotides, nutrients, and a physicochemical milieu. We report a case of repigmentation of gray hairs in lesions of annular elastolytic giant cell granuloma (AEGCG) on the scalp of a 67-year-old man.

Oral squamous cell carcinoma in a case of dyskeratosis congenita.

Oral manifestations of dyskeratosis congenita (DCG) have received little attention in dental literature. This report is a case of dyskeratosis congenita in a 17-year-old female which was associated with oral lesions such as leukoplakia, superimposed candidal infection, desquamative gingivitis, and severe periodontitis. Histopathologic examination of the granular lesion on the right lateral border of the dorsum of the tongue showed well-differentiated squamous cell carcinoma. Etiopathogenesis, clinical features, and laboratory findings of this disease are discussed.

Kindler syndrome.

Kindler syndrome is a rare genodermatosis characterized by acral bullae and photosensitivity. The photosensitivity improves with advancing age and results in progressive poikiloderma and cutaneous atrophy, and many additional features have also been described. This report describes two male Kindler syndrome patients with classical features of acral blistering and photosensitivity in childhood, and subsequent development of poikiloderma, leukokeratosis of oro-ano-genital mucosae, phimosis and meatal stenosis. The first patient had additional ophthalmic features of chronic simple conjunctivitis caused by persistent irritation, multiple stromal nebular corneal opacities and thickened corneal nerves. The second patient showed skeletal changes, namely a dome-shaped skull (turri-cephaly), bifid fourth rib, missing fifth rib, short fourth and fifth metacarpals and mandibular abnormalities. This is the first report of such ophthalmic and skeletal features of Kindler syndrome.

Chronic pigmented purpura associated with odontogenic infection.

Five patients with chronic pigmented purpura associated with odontogenic infection are described. Four patients had Schamberg's disease, and one had itching purpura. These patients were resistant to topical corticosteroid treatment, but appearance of purpuric spots ceased after treatment for periodontitis, pulpitis, or both. No circulating immune complexes were detected, and neither immunoglobulin nor complement was deposited in the papillary vessels of the skin. Odontogenic infection might be one of the precipitating factors for chronic pigmented purpura.
