Epidemiology and pathological progression of erythematous lip lesions in captive sun bears (Helarctos malayanus).

This study investigates the occurrence of erythematous lip lesions in a captive sun bear population in Cambodia, including the progression of cheilitis to squamous cell carcinoma, and the presence of Ursid gammaherpesvirus 1. Visual assessment conducted in 2015 and 2016 recorded the prevalence and severity of lesions. Opportunistic sampling for disease testing was conducted on a subset of 39 sun bears, with histopathological examination of lip and tongue biopsies and PCR testing of oral swabs and tissue biopsies collected during health examinations. Lip lesions were similarly prevalent in 2015 (66.0%) and 2016 (68.3%). Degradation of lip lesion severity was seen between 2015 and 2016, and the odds of having lip lesions, having more severe lip lesions, and having lip lesion degradation over time, all increased with age. Cheilitis was found in all lip lesion biopsies, with histological confirmation of squamous cell carcinoma in 64.5% of cases. Single biopsies frequently showed progression from dysplasia to neoplasia. Eighteen of 31 sun bears (58.1%) had at least one sample positive for Ursid gammaherpesvirus 1. The virus was detected in sun bears with and without lip lesions, however due to case selection being strongly biased towards those showing lip lesions it was not possible to test for association between Ursid gammaherpesvirus 1 and lip squamous cell carcinoma. Given gammaherpesviruses can play a role in cancer development under certain conditions in other species, we believe further investigation into Ursid gammaherpesvirus 1 as one of a number of possible co-factors in the progression of lip lesions to squamous cell carcinoma is warranted. This study highlights the progressively neoplastic nature of this lip lesion syndrome in sun bears which has consequences for captive and re-release management. Similarly, the detection of Ursid gammaherpesvirus 1 should be considered in pre-release risk analyses, at least until data is available on the prevalence of the virus in wild sun bears.

Cutaneous effects associated with fluconazole in patients treated for coccidioidomycosis.

BACKGROUND: Fluconazole is the most commonly used antifungal treatment for various forms of coccidioidomycosis. Although we had anecdotally observed a high proportion of patients reporting cutaneous adverse effects associated with fluconazole treatment, this observation was not well described in the medical literature, and we were unsure of the additional effect of the arid desert environment of Arizona. METHODS: We performed a one-time, voluntary survey of patients with coccidioidomycosis and compared the responses of patients treated with fluconazole with those of untreated patients. RESULTS: From January 1, 2015, to August 22, 2017, 62 fluconazole-treated and 35 untreated patients with coccidioidomycosis provided consent and were enrolled in the study; demographics were similar between the two groups. Among the 62 fluconazole-treated patients, daily dosages ranged from 200 mg to 800 mg. However, most (44/62, 71%) took 400 mg daily, the typical dose for the treatment of coccidioidomycosis. The median fluconazole treatment duration at the time of study participation was 6 months. When compared with untreated patients, those taking fluconazole had more moderate to severe dry lips (74.2% [46/62] vs. 23.5% [8/34]; P < 0.001), dry skin (45.8% [27/59] vs. 22.9% [8/35]; P = 0.03), and alopecia (31.1% [19/61] vs. 11.4% [4/35]; P = 0.004). CONCLUSIONS: For the treatment of coccidioidomycosis, patients receiving fluconazole reported significantly more severe cutaneous effects, including dry lips, dry skin, and alopecia, than untreated patients. Our findings identify an association but do not prove causality.

A comparative analysis of oral and maxillofacial pathology over a 16-year period, in the north of Portugal.

OBJECTIVES: To determine the frequency and spectrum of oral and maxillofacial lesions biopsied in a hospital population in the northern region of Portugal. METHODS: We conducted descriptive analyses of pathology reports from biopsies of oral and maxillofacial lesions performed between 1990 and 2006, in Oporto Hospital Center. Information on gender and age of patient, location of the lesions and the histopathological diagnosis were analysed. RESULTS: The analyses revealed that 1,520 (47.7%) patients were male and 1,666 (52.3%) were female. They had a mean age ± standard deviation of 47.8 ± 18.6 years. The site most frequently biopsied was the labial mucosa (17.5%). A non-neoplastic diagnosis was established in 2,162 (63.3%) cases, potentially malignant disorders in 163 (5.1%) and neoplasms in 886 (27.6%) (403 benign and 483 malignant). The most commonly reported diagnosis was fibroepithelial polyp (n = 186; 15.9%), followed by squamous cell carcinoma (SCC) (n = 158; 13.6%). SCC was the lesion most commonly found in male patients (n = 279; 18.4%) whilst fibroepithelial polyp was the lesion most commonly found in female patients (n = 268; 16.1%). The most common lesion in patients 0-17 years of age was a follicular cyst (n = 25; 12.8%), whereas in patients 18-64 years of age it was a fibroepithelial polyp (n = 299; 13%). SCC was the most common type of lesion found in patients ≥ 65 years of age (n = 160; 24.6%). CONCLUSION: This large sample provides useful information about the incidence and distribution of oral biopsies over a period of 16 years, allowing valuable comparison with other countries. Non-neoplastic lesions were the types of lesion most commonly reported, with fibroepithelial polyp being most frequent. SCC was the second most common diagnosis.

Accuracy of clinical diagnosis for the identification of potentially malignant disorders and malignant lip lesions.

The aim of this study was to assess the accuracy of clinical diagnosis for lip lesions based on sensitivity and specificity. The retrospective analysis focused on the detection of lesions caused by potentially malignant disorders (PMDs) and malignant lesions (n = 1195). All cases were classified as benign, PMD, and malignant lesions. Concordance between diagnoses based on clinical examination and those based on histopathological analysis was assessed, and accuracy for the identification of PMD and malignant lesions was calculated. Histopathological analysis revealed 44 lesion types; PMD and malignant lesions comprised 8.3% of all cases. Compared with histopathological analysis, clinical examination showed 97.4% accuracy for the identification of non-malignant and potentially malignant/malignant cases. Degrees of specific sensitivity ranged from 34% to 77% for different lesions, and were highest for autoimmune (77%) and reactive (72%) lesions. Positive and negative predictive values for the identification of PMD and malignant lesions were 81.9% and 98.9%, respectively. Clinical examination showed a high degree of accuracy for the detection of PMD and malignant lip lesions, indicating good reliability.

Orolingual Angioedema During or After Thrombolysis for Cerebral Ischemia.

BACKGROUND AND PURPOSE: Orolingual angioedema (OLAE) is a life-threatening complication of intravenous thrombolysis. Our objective was to compare outcomes of patients with and without OLAE. METHODS: We prospectively included consecutive patients who received intravenous thrombolysis for cerebral ischemia at Lille University Hospital. We examined tongue and lips every 15 minutes during thrombolysis and ≤30 minutes after. We evaluated the 3-month outcome with the modified Rankin scale (mRS) and compared outcomes of patients with and without OLAE. RESULTS: Of 923 consecutive patients, 20 (2.2%) developed OLAE. None of them needed oro-tracheal intubation. They were more likely to be under angiotensin-converting enzyme inhibitors (adjusted odds ratio [adjOR], 3.9; 95% confidence interval [CI], 1.6-9.7; P=0.005) to have total insular infarcts (OR, 5.0; 95% CI, 1.5-16.5; P=0.004) and tended to develop more symptomatic intracerebral hemorrhages. Results concerning angiotensin-converting enzyme inhibitors were not modified after adjustment for propensity scores (OR, 4.4; 95% CI, 1.6-11.9; P=0.004) or matched analysis based on propensity scores (OR, 3.4; 95% CI, 1.3-8.1; P=0.010). Patients with OLAE did not significantly differ at 3 months for the proportion of patients with mRS score of 0 to 1 (adjOR, 0.9; 95% CI, 0.3-2.1), mRS score of 0 to 2 (adjOR, 0.8; 95% CI, 0.1-1.8), and death (adjOR, 1.1; 95% CI, 0.3-3.8). CONCLUSIONS: OLAE occurs in 1 of 50 patients who receive intravenous thrombolysis, 1 of 10 in case of total insular infarct, and 1 of 6 if they are under angiotensin-converting enzyme inhibitors. Their long-term outcome does not differ from that of other patients.

Lichen planus of the lips: an intermediate disease between the skin and mucosa? Retrospective clinical study and review of the literature.

BACKGROUND: Lichen planus of the lips (LPL) is not frequently described in the literature. The objective of this study is to investigate the clinical outline, behavior, and prognosis of LPL. METHODS: Clinical data of patients with true oral lichen planus (LP) involving the lips, diagnosed and treated at our Oral Medicine Unit (University Federico II of Naples, Italy), have been collected and analyzed. Concurrently, a PubMed search was carried out from 1950 to March 2014 to assess epidemiological and clinical data about LPL. RESULTS: Our case series revealed 13 patients (female/male ratio 0.4) with a mean (± SD) age of 71.85 years (± 6.72). The lower/upper lip involvement ratio was 9, mainly with mixed clinical patterns (76.9%), generally including erosion and mild keratosis. In most cases, the lips were involved with other oral sites but displayed a better evolution of the lesions. The literature review showed 21 reports of LPL (35 patients, female/male ratio 0.4) with a mean (± SD) age of 45.35 years (± 16.19). CONCLUSIONS: In the literature, erosive (28.57%) lower lip lesions showed a clear predominance (lower/upper lip ratio 6.5). One case of malignant transformation was also reported. The prevalence of isolated LPL was clearly reported only in two studies, ranging from 0.51% to 8.9%. In our patients, lesions were mostly found at the inner border of the lower vermillion and presented a tendency for self-limitation, or to regression after treatment, like cutaneous lesions. The lip lesions were small and easy to overlook, and therefore the prevalence of these lesions may have been underestimated.

Incidence and recovery of neurosensory disturbances after bilateral sagittal split osteotomy in different age groups: a retrospective study of 263 patients.

This study aimed to investigate the incidence of neurosensory disturbance (NSD) after bilateral sagittal split osteotomy (BSSO) in different age groups and to assess the probability of sensory recovery in patients aged <19 years, 19-30 years, and >30 years. Hypoaesthesia of the lower lip was assessed subjectively and objectively immediately after BSSO and at 1 week and 1, 6, and 12 months after BSSO. Hypoaesthesia was considered permanent if it was present 1 year after BSSO. The frequency of NSD immediately after surgery was significantly higher in older patients. The cumulative incidence of recovery at 1 year was lower and the mean time to recovery was longer in the older patients, although these differences were not statistically significant. Older age was a significant risk factor for permanent hypoaesthesia, with an incidence of 4.8% per patient aged <19 years, 7.9% per patient aged 19-30 years, and 15.2% per patient aged >30 years. These findings show that the risk of NSD after BSSO is significantly higher in older patients. These results may aid surgeons in preoperative patient counselling and in deciding the optimal age at which to perform BSSO.

A 15-year retrospective study of 160 cases of benign lip lesions.

OBJECTIVE: This study aimed to describe the results of a retrospective analysis of a specific cohort of patients with benign lip lesions encountered in the last 15 years in the School of Medicine at Karadeniz Technical University. METHOD: A total of 312 patients were managed for lip lesions during the period 2000-2014. Data from 160 samples of benign lip biopsies were retrieved from the pathology laboratory records. RESULTS: The study group included 20 different histopathological types of lesions, with mucocele being the most frequent lesion (43.13 per cent). The other frequent lesions were chronic inflammatory infiltrate (11.25 per cent), intradermal naevus (5.63 per cent), pyogenic granuloma (5.63 per cent), fibroma (5 per cent) and papilloma (5 per cent). Mucocele was significantly more common in younger patients (p < 0.001). CONCLUSION: Knowledge of the epidemiology and distribution of oral mucosal lesions is essential to promote early diagnosis and treatment. Further epidemiological studies exploring the causal relationships and risk factors for lip lesions are necessary for a better understanding of lip diseases.

[Child care management in maxillofacial humanitarian mission]. / Prise en charge de l'enfant en mission humanitaire maxillofaciale.

Our practice in a humanitarian (or crisis) context differs from what we experience in daily practice. There are several reasons for this. First, the diseases encountered are sometimes unfamiliar, such as sequelae of noma, or the presentation of familiar diseases may be unusual, such as facial malformations seen at a late stage. Secondly, these missions take place in developing countries, and consequently, evaluation and anticipation of possible malnutrition should be considered, especially because facial diseases themselves may be responsible for nutritional problems. Lastly, conditions are often difficult, occurring in an unusual environment, and we sometimes have to face communication and equipment problems. The goal of our work, based on a 15-year experience (in Bamako and Mopti with the Association "Santé et Développement", and in Ouagadougou with the organization "Les enfants du noma") and the analysis of literature, is to point out these features and maybe to be helpful to others.

Mucosal leishmaniasis of the lip: an emerging clinical form in Tunisia.

BACKGROUND: Mucosal leishmaniasis (ML), which mostly occurs in the New World, is mainly associated with Leishmania braziliensis. Primary lip ML is very rare in the Mediterranean basin and particulary in Tunisia despite the endemicity of both cutaneous and visceral leishmaniasis in this area. OBJECTIVES: To highlight a recent emergence of primary lip ML in Tunisia, to describe its epidemiological and clinical features and to identify the causative Leishmania species. METHODS: Epidemiological, clinical and therapeutic data of 10 cases presenting a ML of the lip were collected. Diagnosis confirmation of leishmaniasis was obtained by microscopic examination of Leishmania parasites in Giemsa stained smears of the lesion sampling and in cutaneous biopsies. Polymerase chain reaction (PCR) detecting Leishmania DNA directly from dermal scraping was also performed for diagnosis and species identification. RESULTS: Seven men and three women with lip ML were diagnosed during the last 6 years (2008-2013). The mean age was 29.7 years. Clinical presentation was characterized by an infiltrated and ulcerated plaque leading to macrocheilitis involving the upper lip in eight cases and the lower lip in two cases. Mean diagnosis delay was 6.9 months. PCR identified L. infantum in seven cases and L. major in two cases. Seven patients received intramuscular injections of meglumine antimoniate (MA) and three patients received both MA intralesional injections of MA and cryotherapy. A clinical remission was rapidly observed in all cases (on average in 2.2 months). CONCLUSIONS: Primary lip ML is emerging in Tunisia. Macrocheilitis of the upper lip is the main clinical presentation. PCR revealed more sensitive than direct examination in the diagnosis of such form (P < 0.01). Leishmania infantum was the most identified species (7 cases) while L major was involved in only two lesions. A benign local evolution and a rapid recovery were observed in all cases after MA treatment.

Use of submandibular gland flap for repairing defects after tumor resection in the infratemporal region.

OBJECTIVE: To investigate the application of submandibular gland flap with facial artery and vein pedicle, for repairing defects following tumor resection in the infratemporal region. PATIENTS AND METHODS: Fifteen patients, including eight males and seven females ranging in age from 21 to 73 years, underwent surgical resection of tumors in the infratemporal region. Tumors were exposed using the submandibular incision approach and completely resected after pulling and rotating the mandible laterally. Mandibular osteotomy was performed for larger tumors or those that were not completely exposed. After tumor resection, the submandibular gland flap was used to fill up the residual defect following tumor resection. RESULTS: The incisions healed well without exudation or infection (primary healing) postoperatively in all the patients. Long-term follow-up showed no tumor recurrence in all cases. Seven of the patients who underwent mandibular ramus osteotomy had numbness of the lower lip due to inferior alveolar nerve injury. No other complications were observed postoperatively. CONCLUSION: The submandibular gland flap with facial artery and vein pedicle is a reliable, effective, and easy approach for repairing the defects caused by tumor resection in the infratemporal region, and has great potential for application in the clinical setting.

Prevalence of lip and perioral Ephelides in beach workers.

BACKGROUND: Ephelides are small hyperpigmented macules common in the skin, presenting as areas with increased melanin production. Ephelides are observed in genetically predisposed individuals, particularly fair-skinned people highly susceptible to sunburn. OBJECTIVES: This study aimed to determine the prevalence of lip and perioral ephelides in 362 beach workers in the city of Natal (Rio Grande do Norte) and to investigate potential associations with sociodemographic, occupational and general health. METHODS: For this purpose clinical tests were performed by calibrated examiners in the epidemiological area around the lips and the area bounded laterally by the nasolabial groove and at the bottom by the chin. A questionnaire was completed and assessed. The possible associations between sociodemographic variables, occupational and general health with the presence of lip and perioral ephelides were evaluated by chi-square test for a significance level of 5%. RESULTS: Approximately one third of the workers were affected by perioral ephelides (33.7%) and around a quarter of them by lip ephelides (24.0%). Gender was the only variable significantly associated with the presence of perioral ephelides (p = 0.002), unlike lip ephelides which proved to be significantly associated with habits (p = 0.036) and alcoholism (0.030). CONCLUSIONS: The prevalence of ephelides in lip and perioral region was high in the study population, with gender and certain habits associated with its occurrence.

Efélides são máculas hiperpigmentadas pequenas, comuns na pele, que constituem uma área com maior aumento da produção de melanina. São observadas em indivíduos geneticamente predispostos, de pele clara, com grande suscetibilidade a queimaduras solares. Esse estudo teve o propósito de verificar a prevalência de efélides labiais e periorais em 362 trabalhadores de praias do município de Natal/RN e investigar potenciais associações com variáveis sociodemográficas, ocupacionais e de saúde geral. Para tanto, foram realizados exames clínicos por examinadores calibrados, na área correspondente aos lábios e na área delimitada lateralmente pelo sulco nasolabial e inferiormente pelo mento, além de preenchimento de questionário validado. As possíveis associações das variáveis sociodemográficas, ocupacionais e de saúde geral com a presença de efélides labiais e periorais foram avaliadas pelo teste do qui-quadrado para um nível de significância de 5%. Aproximadamente um terço dos trabalhadores foi acometido por efélides perioral (33,7%) e um quarto por efélides labial (24,0%). O gênero foi a única variável que se mostrou associada significativamente com a presença de efélides periorais (p=0,002), ao contrário das efélides labiais que mostrou-se associada significativamente com hábito (p=0,036) e etilismo (0,030). Conclui-se que a prevalência de efélides em região perioral e labial foi elevada na população estudada e o gênero e hábitos ...

HPV oral lesions in HIV-infected patients: the impact of long-term HAART.

BACKGROUND: Since the introduction of highly active antiretroviral therapy (HAART), an increase in the frequency of human papillomavirus-associated oral lesions (HPV-OL) has been observed. Thus, the aim of this study was to determine the prevalence and factors associated with HPV-OL in Mexican HIV-infected patients, as well as its genotyping, in the HAART era. METHODS: In a cross-sectional study developed at an HIV/AIDS referral center in Mexico City, HIV-infected patients were consecutively included from 2004 to 2011. An oral exam was performed; lymphocyte CD4(+) count, HIV-viral load, CDC-stage, and HAART use were recorded. HPV-OL samples were taken for routine histopathological analysis (H-E) and HPV-DNA amplification/sequencing. Logistic regression models were performed and the interactions tested using the STATA software. RESULTS: Among 787 HIV patients, 55 (6.9%) showed HPV-OL. HPV-OLs were independently associated with age (≥40 years) and with a longer time of HAART use (≥12 months). The most frequent lesion was squamous cell papilloma in 22 (40%) cases, followed by multifocal epithelial hyperplasia in 15 (27.3%) cases. Labial mucosa was the most common site involved (56.4%). Of the sequences obtained, 65.4% corresponded to low risk and 11.5% to high risk. Mixed high- and low-risk infection were identified in 7.7% of the cases. CONCLUSIONS: Human papillomavirus-associated oral lesions were associated with older age and longer HAART use. All lesions were benign in nature and most of the HPV sequences corresponded to low-risk types. The rise of HPV-OLs in HIV patients on HAART may be related with the longer life expectancy of individuals with an impaired immune system rather than a direct effect of HAART.

OBJECTIVE: To assess the prevalence and factors associated with orolabial lesions caused by sun exposure in beach workers. METHODS: Cross-sectional study with 362 beach workers from five urban beaches in the city of Natal, northeastern Brazil, from August to December 2010. All subjects completed a validated questionnaire to collect personal, occupational, and health-related information and underwent an orolabial clinical examination by trained examiners. Potential associations between sociodemographic, occupational, and health-related variables and the presence of orolabial lesions were assessed using the chi-square test at a 5% significance level. The multivariate analysis was performed using Poisson regression. RESULTS: Of the 362 workers examined, 27.1% had orolabial lesions. Of these, 76.8% were males, 61.6% dark or black skinned, 94.5% informal workers, and 85.4% reported sun exposure. Most (81.1%) reported using sun protection methods including sunscreen (38.7%), lip balm (15.3%), and cap/hat (72.4%). Twenty-eight percent reported smoking and 48% regular drinking. Sun protection with cap/hat was associated with orolabial lesions caused by sun exposure. CONCLUSIONS: There was found a high prevalence of orolabial lesions in workers exposed to sunlight that was associated with the use of a cap/hat as a sun protection method.

Multifocal cutaneous ORF virus infection in goats in the Amazon region, Brazil.

Orf virus is the etiological agent of contagious ecthyma, a severe exanthematic disease that affects small ruminants. Orf virus is zoonosis that is associated with occupational contact with infected animals in human disease. Clinically, contagious ecthyma is characterized by the appearance of vesicles, pustules, ulcers, and papillomatous proliferative lesions on the skin of the lips and nostrils. Here we describe a case of lethal cutaneous multifocal Orf virus infection in goats in the Amazon region of Brazil. Exanthematic lesions were collected and epidemiological and clinical data were obtained. Orf virus was detected using PCR amplification of the whole B2L, VIR, and VEGF open reading frame. Phylogenetic analysis revealed that this virus clustered together with the Orf virus samples isolated during classical contagious ecthyma. The present work is the first to report a severe proliferative Orf virus case in South America.

Orodental manifestations of facial port-wine stains.

BACKGROUND: Patients with facial port-wine stains (PWS) often demonstrate oral manifestations of their disorder; however, the spectrum and prevalence of such findings among a cohort of patients with PWS has not been established. As a result, dermatologists and oral health specialists may be uncertain how to counsel their patients with PWS regarding oral hypervascularity, bony oral changes, and oral hygiene. OBJECTIVES: We sought to identify physical findings and complications involving the teeth, oral cavity, and perioral structures in individuals with facial PWS. METHODS: This was a cross-sectional study of 30 patients with facial PWS. Descriptive data were collected through anonymous paired surveys completed by patients and their dentists, and analyzed (Fisher exact test) for trends based on physical findings and stage of the PWS. RESULTS: The most common orodental manifestations according to patients were enlargement of the lip (53.3%), stained gums (46.7%), abnormal bite (30%), and spontaneous bleeding of the gums (26.7%). Staining of the gingiva correlated significantly with gingival hyperplasia (P = .006), maxillary hyperplasia (P = .014), and widened interdental spaces (P = .002), and in all cases gingival staining predated these findings. Lip hyperplasia was reported more frequently by patients than by their dentists (50% vs 18.2%, P = .008). Orodental manifestations were more common among patients with darker and thicker PWS. Hemorrhage after dental procedures was rare (4.5%). LIMITATIONS: Modest sample size and difficulty recruiting control subjects are limitations. CONCLUSIONS: Facial PWS commonly affect the orodental structures, and intraoral staining may predict future complications.
