Moebius Syndrome: Clinical Manifestations in a Pediatric Patient

Moebius syndrome is a congenital, nonprogressive disorder clinically characterized by loss of facial expression, impaired stomatognathic system functions, incapacity to close the eyelids, and several oral impairments. The purpose of this paper was to present the clinical manifestations and the dental treatment in a 5-year, 2-month-old male Moebius syndrome patient. The child presented with facial asymmetry, difficulty performing facial mimic movements and pronouncing some letters, and compromised suction, mastication, breathing, and deglutition. An intraoral examination revealed hypofunction of the perioral muscles, cheeks and tongue, ankyloglossia, anterior open bite, and absence of carious lesions and dental anomalies. The dental treatment consisted of frenectomy and further placement of a removable orthodontic appliance with a palatal crib for correction of the anterior open bite. After 12 months of follow-up, anterior open bite decreased and speech, deglutition, and mastication improved.

Management of an Unusual Presentation of Ascher Syndrome

Ascher syndrome is defined by the association between double lip, blepharochalasis, and nontoxic goiter. Because it is a rare disease, it is most often misdiagnosed, despite its implications for quality of life. We report a variation of an incomplete type of Ascher syndrome affecting the upper lip, upper eyelids, and lateral canthi of a young male patient. The surgical management, follow-up, and a brief overview of the syndrome are described. The results presented show an aesthetic and functional improvement of the facial deformities.

Celulite juvenil canina – relato de casos

Juvenile cellulitis or juvenile sterile granulomatous lymphadenitis is a rare disorder that affects puppies between three weeks to six months years old. Clinical signs include alopecia, edema, papules, pustules and crusts especially on eyelids. Definitive diagnosis requires cytological and histological evaluation and early and aggressive therapy is recommended, once scars after recovery can be severe. The choice treatment is the high dose of corticosteroids use such as prednisone. Three animals of canine species were attended at the Veterinary Hospital Clinical Small Animal Service presenting different clinical signs. Hemogram, skin lesions and submandibular lymph nodes cytological examination was collected and analyzed. The treatment was instituted, using cephalexin (22mg/kg, twice daily) up to control of secondary bacterial infection, and prednisone (2mg/kg, once a day) until clinical resolution. Complete cure was obtained at the end of treatment. The aim of this work is to report three clinical cases of juvenile cellulitis in dogs.

A new species of Proceratophrys (Anura: Leptodactylidae) from the Amazon rain forest

A new Proceratophrys from Rondonia, Brazil, is described based on adults and tadpoles. The new form represents a species with eyelids bordered by large, irregularly arranged, warts; postocular swellings absent; snout obtuse with flaring lip in profile; tympanum defined as a depression in the skin; and dorsal surfaces of body and leg bearing high elevated warts. The new species extends the known distribution of the genus to the northwest and represents the first described species of Proceratophrys from the Amazon rain forest. We discuss the species group arrangement in Proceratophrys based on morphology, geographic distribution, and habitat.

Hidrocistoma écrino e apócrino na pálpebra - Casuística na Faculdade de Medicina de Botucatu- São Paulo

Background - Hidrocystomas ecrine and apocrine may be observed in the eyelids. Objective - The purpose of this study was to observe the occurrence of eyelid hidrocystoma (eccrine or apocrine), as well as the relation between clinical and histopathological diagnosis. Patients and Methods - 42 patients were selected, with a total of 52 lesions, attended between January 1990 to April 1999, at the Botucatu Medical School, with diagnosis of hidrocystoma confirmed by histopathology diagnosis. Result - Hidrocystoma occurred in 0.07% of patients undergoing lesion removal during this period. Eccrine and the apocrine hidrocystoma were frequently observed in female patients, aged over 40 years. The clinical picture ranged from about 1 to 5 years. The lesions were mainly located in the lower eyelid and presented as a single lesion. The clinical diagnosis agreed with the histopathological diagnosis in 67.31% of the apocrine hidrocystomas, and 9.62% of the eccrine hidrocystomas. Conclusions - Apocrine hidrocystoma was the most frequently observed eyelid hidrocystoma. The correlation between clinical and histopathological diagnosis was higher for apocrine hidrocystomas.

Argon laser for treatment of benign eyelid tumors

Small lesions located in the skin might be treated using the laser system. The purpose of this is to report the therapy of benign eyelid tumors using argon laser. Forty-four benign eyelid tumors were treated using argon blue-green laser with spot size of 500 μm, power from 1000 to 1200 mW and 0.3 second exposure time. The eyelid tumors were located mainly in the upper eyelid (65.9%) and the skin tag was the most frequent treated lesion (43.2%). The average number of laser shots to treat the lesions was 165. There was not observed any complication and all patients were satisfied with the results. The authors are considering the argon laser a benefit therapeutic method to treat benign tumors located in the eyelids.

Palpebral dimensions in Brazilian children: Assessment based on digital images

Purpose: To determine palpebral dimensions and development in Brazilian children using digital images. Methods: An observational study was performed measuring eyelid angles, palpebral fissure area and interpupillary distance in 220 children aged from 4 to 72 months. Digital images were obtained with a Sony Lithium movie camera (Sony DCR-TRV110, Brazil) in frontal view from awake children in primary ocular position; the object of observation was located at pupil height. The images were saved to tape, transferred to a Macintosh G4 (Apple Computer Inc., USA) computer and processed using NIH 1.58 software (NTIS, 5285 Port Royal Rd., Springfield, VA 22161, USA). Data were submitted to statistical analysis. Results: All parameters studied increased with age. The outer palpebral angle was greater than the inner, and palpebral fissure and angles showed greater changes between 4 and 5 months old and at around 24 to 36 months. Conclusion: There are significant variations in palpebral dimensions in children under 72 months old, especially around 24 to 36 months. Copyright © 2006 Informa Healthcare.

Autologous orbicularis muscle for filling facial foldsan experimental and clinical study

Purpose: To present a technique for filling facial folds by using autologous orbicularis oculi muscle, based on an experimental model. Methods: two studies are presented: (1) an experimental study using 15 albino guinea-pigs from which a strip of the sural triceps muscle was removed and implanted in the subcutaneous tissue of the dorsal area. The animals were sacrificed 7, 30 and 60 days after the implantation, and the material was histologically evaluated. And (2%) an interventional prospective clinical trial carried out on 20 patients referred to blepharoplasty surgery. They received autologous preseptal orbicularis muscle for filling facial folds. The results where evaluated by patients satisfaction and clinical exam. Results: the sural tricep muscle, when implanted in the subcutaneous tissue, resulted in fibrosis. The patients whom received autologous orbicularis muscle implanted for filling facial folds showed that the procedure can be successfully carried out. Conclusions: autologous preseptal orbicularis muscle is a good material for filling facial folds. Cicatricial tissue will be formed on its implantation site, filling the tissue gap that forms the folds on the skin.

Avaliação histológica e morfométrica do retalho axial oris angularis e da terapia por ondas de choque aplicados a defeito palpebral experimental em cães

Considering that the cutaneous flap can be affected by isquemic complications the extra corporeal shock wave therapy (ESWT) was described as rescue techniques. The present study was developed to analyze histological and with morfometry, twenty one skin samples treated or not with the shock wave therapy, obtained from flap's distal border, used in this study to repair eyelids' experimental defects in dogs. The flap with or without ESWT did not show any histological sign of inflammatory or atrophic alterations. Both group treated showed similar morphometrical characteristics. The ESWT with the protocol used in this study (2500 impulses at 0,15 mJ/mm 2) did not demonstrate significant clinical outcomes as a rescue technique when applied over the oris angularis flap, however results showed no signals of collateral deleterious effects.
