The advertisement call of Dendropsophus nahdereri (Anura, Hylidae, Dendropsophini).

The Dendropsophus marmoratus group is composed of eight species known for their explosive breeding habits and morphologically characterized by a bark-like dorsum, warty skin around the lower lips and an extremely large vocal sac. Within this group, D. nahdereri is the only species with distribution restricted to the southern region of Brazil. Apart from the original description and its tadpole, nothing else is known about this species. Using a mechanistic definition of note, we describe the advertisement call of D. nahdereri, which is similar to the advertisement calls of other species of the group and frequently has "final pulseclusters" as defined in the text.

Oral-Facial-Digital Syndrome Type 1: Oral Features in 12 Patients Submitted to Clinical and Radiographic Examination

Objective: To evaluate the oral features in individuals with oral-facial-digital syndrome type 1 (OFD 1), previously diagnosed by the Genetic Sector of the Hospital of Rehabilitation of Craniofacial Anomalies of the University of São Paulo (HRAC-USP).Design: Twelve patients with OFD 1 were examined clinically and radiographically; their medical files were also evaluated.Results: Associated oral malformations were observed in all patients (100%). The most frequent findings were tongue hamartomas, multiple buccal frena, asymmetric lips, asymmetric tongue, and bilateral maxillary gingival swelling. Interestingly, atrophy of the maxillary midline frenum was also observed in all the individuals examined.Conclusions: Several extra and intraoral alterations were observed in patients with OFD 1. The authors suggest the inclusion of atrophy of the maxillary midline frenum as a commonly found characteristic of OFD 1.

Biologia populacional de Pareiorhina rudolphi (Loricariidae, Hypostominae) na microbacia do Ribeirão Grande, serra da Mantiqueira oriental, Estado de São Paulo

Pareiorhina rudolphi was sampled in streams of the Ribeirao Grande system, eastern Serra da Mantiqueira (22[degree]47[minute]08[second]S, 45[degree]28[minute]17[second] W). Samplings were carried out using an electrofishing device, during the months of July/2001, October/2001, February/2002 and April/2002. Sex-ratio diverged significantly from the expected 1: 1 ratio([chi]2 = 6.53; p < 0.05), standing at 1.6:1 (female: male). The spawning period for Pareiorhina rudolphi lasts from spring to summer, with, the highest observed, in October and February by the gonadosomantic index and the relative condition factor coincided with the spawning period. The length at sexual maturity of P. rudolphi is about 4.45 cm for both sexes. The absolute fecundity was low, and ranged from 4 to 11 oocytes. The periphyton was used as a direct food source by the species, which remain attached to the substrate with their large circular lips, and use their conspicuous Slightly Yellowish teeth to graze the periphyton. The growth parameters, natural mortality rate and survival rate for P, rudolphi were respectively: K = 0.35 year-1, L[infinity] = 7.2 cm, tmax = 8.6 years, M = 1.1 year-1, S = 33%. The characteristics presented by P. rudolphi occur in the environment function of a population adjustment, and not of species abundance.

Naso-orbicular tissue necrosis by Streptococcus parasanguis in a patient with Fanconi anemia: Clinical and laboratory aspects

Fanconi anemia (FA) is a rare autosomal recessive disorder, characterized by pancytopenia and progressive hypoplasia of the bone marrow. A 23-year-old woman with FA showed severe pancytopenia and developed an abscess on the infraorbicular region on the right side of the face that progressed to phlegmon and caused tissue necrosis of the nostrils, nasal septum, nasal fossa, and posterior orbital region. Laboratory examination showed Streptococcus parasanguis as the etiologic agent of the phlegmon. Supportive treatment was recommended due to donor incompatibility for bone marrow transplant. The intraoral examination showed spontaneous gingival bleeding, edema of the interdental papillae, hematomas on the superior and inferior lips, bacterial and fungal infections, and adequate oral hygiene. The patient was treated with the administration of an antibiotic (imipenem), an antifungal (amphotericin B), and mouth washing with antiseptic solutions. Periodontal prophylaxis and orientation to and control of oral hygiene and diet were also used during the remission period. For functional and esthetic rehabilitation of the alar regions and nasal dorsum, an acrylic resin nasal prosthesis was made, supported by a spectacle frame.

On the morphology of the juvenile stages of Ampulex compressa (Fabricius 1781) (Hymenoptera, Ampulicidae)

Ampulex compressa is a cockroach-hunting ampulicid wasp. In this survey we describe its egg, mature larva, along with the 1st and 2nd larval instars and cocoon, with emphasis on the characters considered important to the phylogeny of apoid wasps. It shares the following traits with the Sphecidae: reduced head setae, absence of antennal papilla, three antennal sensilla on antennal orbit, broad and strongly emarginate labrum, and spinneret with prominent raised lips. In common with other Ampulicidae, it has integument of the body granulose and without setae, mandibles with four or five teeth and lacking basal setae, maxillary palp larger than galea and discrete parietal bands. Distinct from the other Ampulicidae, it has a deep median longitudinal groove in the area above the salivary lips, a distinct group of five sensilla on the subgenal area, and lacks spines on the spiracular peritreme.

Clinical manifestations and oral findings in fraser syndrome

This article is the first known case report of Fraser syndrome in the dental literature. Its purpose was to present the clinical manifestations, oral findings, and dental treatment of a 14-year, 10-month-old female patient. Fraser syndrome is a rare recessive autosomal genetic disorder characterized by multisystemic malformation, usually comprising cryptophthalmos, syndactyly, and renal defects. The child presented with: (1) hydrocephaly; (2) face asymmetry; (3) low-inserted ears; (4) flat nose bridge; (5) cryptophthalmos; (6) bilateral absence of eyeballs; (7) hypertelorism; (8) syndactyly on the left fingers and toes; (9) skeletal defects; and (10) lower limb asymmetry. The intraoral examination revealed: (1) complete primary denture; (2) malocclusion; (3) tooth crowding; (4) ogival palate; (5) normal labial frena; (6) absence of lingual frenum (not compromising the tongue movements); (7) parched lips; (8) supragingival calculus adhered to all tooth surfaces; and (9) moderate gingivitis. The dental treatment consisted of periodic monitoring of the patient's oral health status and supragingival scaling associated with topical applications of 0.12% chlorhexidine digluconate gel at 2-week intervals to reduce gingivitis.

Studying the satisfaction of patients on the outcome of an aesthetic dermatological filler treatment

Background: Many factors contribute to extend productive life in the modern world. Competition makes people worry about physical appearance, mosftly in respect to facial and skin aging. This has motivated new developments in cosmetic dermatology and the need of evaluating patient satisfaction with the new proposed treatments. Poll questionnaire has been used for such evaluation, and the analysis of the electroencephalogram (EEG) mapping obtained while the patient answers the satisfaction questionnaire may render the results less subjective. Objectives: The purpose of this paper is to study the satisfaction of a group of 33 women (mean age, 44.years) treated with hyaluronic acid filling of nasolabial folding or lips, combining the EEG brain mapping and questionnaire techniques. Methods: At the third month of evaluation, two networked personal computers were used for the EEG recording and for presenting the patient with a questionnaire about her well-being feeling; self-evaluation of her face; her satisfaction with the results of the aesthetic treatment; how the family, friends, and people at work evaluated the result of the treatment; and her decision to repeat the treatment and to recommend it to friends and family. Results: Poll results showed that patients were feeling well and were satisfied with the results of the aesthetic treatment. Furthermore, the regression EEG mappings showed patients to be satisfied with their appearance and with the treatment involving similar brain areas. Conclusion: Patients decided to undergo the treatment because they were already considering it (54%) or because they were dissatisfied with their lips or nasolabial folding (52%). The fact that the treatment was free of charge solidified the decision. Patients consider themselves as good-looking and they wanted to preserve such a condition. © 2008 Wiley Periodicals, Inc.

Inter-relação entre o perfil dos lábios superiores e a posição da maxila e dos incisivos superiores em pacientes adultos

Introduction: Professional evaluations and lay person evaluations as well do not show a clear relationship between hard tissue and soft tissue profiles in orthodontic patients. However, there are concrete evidences that the orthodontist can change the facial profile of the patients. aim: This research project aimed to measure the contribution of the bone structure of the maxilla and the upper incisors inclination to the upper lip profile. Methods: A sample of 147 adult patients, 58 male and 89 female, aged from 15 to 49 years, the most of them Caucasians, was retrospectively selected from the private practice of one of the authors. It was assumed that the esthetic facial profile depends of the hard tissues that support it besides its own features as thickness, strength and composition. The present research model was not set to control the intrinsic features of the soft tissue. To compose the Ricketts and Burstone esthetic lines, the main cephalometric variables were SNA and U1PP, when concomitantly considered. Results: The regression coefficients, although statistically significant, did not contributed expressively to explain the regard variables, the pre-defined esthetic lines. Furthermore, the results suggested a negative correlation between the maxillary position (SNA) and the anteroposterior inclination of the upper incisors (U1PP), possibly due to the compensatory action of the lips and the tongue. Conclusion: The results did not presented conclusive scientific evidences about the contribution of the hard tissues for the soft tissue facial profiles.

Retention mucocele on the lower lip associated with inadequate use of pacifier

Mucocele forms because of salivary gland mucous extravasation or retention and is usually related to trauma in the area of the lower lips. Ruptured ducts release the mucous that accumulates into adjacent tissues, leading to swelling. This report describes a large mucocele involving the lower lip, which was produced in a child by incorrect use of a pacifier. A few important concepts are discussed to help clinicians in the diagnosis and treatment of this pathology. © 2010 Dermatology Online Journal.

Morphology of collagen fibers and elastic system fibers in actinic cheilitis

Background: Actinic cheilitis (AC) is a premalignant condition intimately related to exposure of the lips to sun rays. Aim: The objective of this study was to evaluate the elastic and collagen fibers in the lamina propria of AC. The degree of epithelial atypia was correlated with the quantity of elastic and collagen fibers. Materials and Methods: Fifty-one cases were investigated. One slide was stained with hematoxylin-eosin for the evaluation of atypia, the second was stained with Weigert′s resorcin-fuchsin for the assessment of elastic fibers, and the third slide was stained with Mallory′s trichrome for the analysis of collagen fibers. Results: Ordinal logistic regression analysis revealed a significant correlation between the presence of atypia and collagen fibers (P<0.05). Conclusions: It was concluded that there seems to be a reduction in the quantity of collagen fibers in cases of moderate and severe atypia. No correlation was observed between the degradation of elastic system fibers and the grade of dysplasia.

Lip cavernous hemangioma in a young child

Hemangiomas are benign tumors of infancy and childhood, characterized by a phase of fast growth with endothelial cell proliferation, occurring in 10-12% of children at 1 year of age. It is known that hemangiomas of infancy are most commonly located on the head and neck region (around 60% of cases) and occur more frequently in the lips, tongue, and palate. Approximately 50% of hemangiomas have complete resolution, and 90% of them are resolved up to the age of 9. Complications occur in only 20% of the cases, the most common problem being ulceration with or without infection. The treatment depends on lesion location, size and evolution stage, and the patient's age. Surgery is usually indicated when there is no response to systemic treatments, or even for esthetic reasons, being performed as a simple excision in combination or not with plastic surgery. This paper reports a case of lip cavernous hemangioma in a 4-year-old child, who was submitted to 3 sessions of vascular sclerosis due to the size of the lesion, before undergoing simple excision of the hemangioma. Two years of postoperative clinical follow-up shows treatment success with no recurrence of the lesion.

Avaliação da segurança e eficácia de novo preenchedor à base de ácido hialurônico no tratamento dos sulcos nasolabiais e contorno dos lábios

Introduction: The use of dermal filling techniques for soft tissue augmentation has greatly increased in recent years. Hyaluronic acid is one of the most used temporary dermal fillers in the treatment of facial wrinkles, furrows, and folds due to its effectiveness and safety. Objective: To evaluate the efficacy and safety of Perfectha®, a new hyaluronic acid filler, for nasolabial folds and lip correction. Methods: Open, multicenter study comprising 87 women. Efficacy was evaluated by the Global Aesthetic Improvement Scale and the Wrinkle Severity Rating Scale. Safety was evaluated through observation and the reporting of side effects. Results: One week after the injection of the filler, improvement in nasolabial folds and lips was observed in 86% and 89% of the women, respectively. Mild or moderate transient inflammatory reaction and ecchymoses occurred in 15% and 9% of patients, respectively, mainly in nasolabial folds. Two patients presented labial herpes simplex after treatment of the lips. The good results were maintained in 76% and 57% of women for nasolabial folds and in 72% and 45% of women for lips after 3 and 6 months, respectively. Conclusion: Perfectha® was effective and safe for these indications.

Epidemiologia do Padrão Face Longa em escolares do Ensino Fundamental do município de Bauru - SP

OBJECTIVE: This study aimed to classify and determine the prevalence of individuals with vertical alteration of facial relationships, according to the severity of discrepancy, especially individuals with long face pattern. METHODS: The sample was composed of 5,020 individuals of Brazilian nationality, of both genders, aged 10 years to 16 years and 11 months, attending fundamental schools at the city of Bauru-SP. Examination of facial morphology comprised direct observation of the face in frontal and lateral views, always with the lips at rest, aiming to identify the individuals presenting vertical alteration of facial relationships. After identification, these individuals were scored, according to severity, into three subtypes, namely mild, moderate and severe. The prevalence of individuals with long face pattern considered only the individuals scored as subtypes moderate and severe. RESULTS: There was prevalence of 34.94% of vertical alteration of facial relationships and 14.06% of long face pattern. CONCLUSIONS: The results obtained in this study revealed that the prevalence of vertical alteration of facial relationships and long face pattern was higher than reported in the literature.

Undesirable effect of cosmetic lip augmentation with autologous fat tissue

Background: Facial cosmetic procedures are commonplace nowadays, especially techniques that aim to increase lip volume. Full lips provide a youthful, healthy, feminine and sensual appearance. There are many techniques and materials used to recover the loss of contour that occurs with age. Case presentation. An unusual case of fat tissue accumulation following cosmetic upper lip augmentation in a 61 year-old female was reported. Surgical treatment was performed for esthetic concerns. Microscopically, the tissue removed was composed of muscle fibers and mature adipocytes. Conclusion: Undesirable effects of esthetic treatment can occur and the clinician should be familiar with such complications to diagnose and manage them. © 2013 Kaminagakura et al.; licensee BioMed Central Ltd.
