Recurrent oral pyogenic granuloma in port-wine stain

Abstract: Pyogenic granuloma (PG) is a benign inflammatory lesion, nonneoplastic in nature, which occurs in the oral cavity and skin. This lesion arises in response to various stimuli such as low-grade local irritations, traumatic injury, or hormonal factors. Recently, in some cases, the occurrence of recurrent PGs in skin associated with vascular lesions, such as port-wine stains, has been described. It has been postulated that this association is promoted by arteriovenous anastomoses in the vascular lesions, leading to the development of PG. The authors discuss 2 cases of recurrent PG in patients with a port-wine stain, and the treatment options adopted.

Tratamiento de la hiperhidrosis palmar primaria por acupuntura: a propósito de un caso

Primary hyperhidrosis is an excessive sweating disorder that occurs in axillae, palms, soles, and craniofacial region. According to Traditional Chinese Medicine (TCM) it is a water metabolism disorder. This study presents a case report treated with TCM, showing more satisfactory results than those by conventional treatments.

O desenho-estória na atenção psicológica a crianças na fase pré-cirurgica

The hospitalization process generates stress and, for a child who has already experienced a surgery can suffer from threatening, anxiety and distress. This search examines the experiences of children indicated for different craniofacial surgery which in many cases require more than esthetic or reconstructive surgery. It is quantitative and qualitative study, descriptive and comparative. The sample is intentional and it is made up of ten children, five boys and five girls in the pre-surgical Hospital for Rehabilitation of Craniofacial Anomalies HRAC-USP, Bauru-SP. As a tool for data collection, the design-themed story and data are used from subsequent survey developed by Walter Trinca. The results indicate that the design-themed story is suitable for the identification of the kid's childhood experiences in helping to deal with the stressful situation. Some of the children reveal their feelings of anxiety and fear and manifest other defenses such as denial. In all cases it identifies emotional states of concern such as anxiety and fear, or also denial of those feelings. It was concluded by the need of creating more favorable conditions in order to identify and address childhood experiences compared to surgery in a hospital environment, proposing the designthemed story technique that reveals those experiences. It emphasizes the relevance of psychological intervention in the hospital environment, considering childhood fantasies and feelings that generate or intensify emotional states of anxiety, fear and distress in pre-surgical level.

Prótese de palato em sujeitos com disfunção velofaríngea: expectativa e ansiedade

Cleft lip and palate (CLL) is a very common craniofacial anomaly. The cleft is usually corrected with surgery which may fail resulting in velopharyngeal dysfunction (VPD). The use of palatal prosthesis is an alternative treatment for correcting both, CLP and VPD. This study evaluated anxiety symptoms expectations of subjects of both genders, with velopharyngeal dysfunction, referred to palatal prosthesis program for VPD treatment. In this cross sectional and descriptive study 30 subjects with velopharyngeal dysfunction, aged 15 to 64 years old (mean age of 28) were interviewed at the Hospital for Rehabilitation of Craniofacial Anomalies (HRAC). All subjects referred to the palatal prosthesis program at HRAC in the year of 2005 were considered for participation in the study but only the first 30 candidates were included. A questionnaire addressing expectation elaborated by the researcher and the Beck Scale on anxiety were used. All subjects showed expectation regarding speech modification. Changes in professional and affective aspects of their lives after changes in speech were obtained with palatal prosthesis were the most reported expectations. Subjects’ age and gender influenced anxiety levels significantly which were minimum across subjects. High levels of expectation were more frequent than anxiety in the sample population.

Comparative analysis of the cranial osteology and evolutionary traits of micrastur gilvicollis, micrastur ruficollis and micrastur semitorquatus (aves: falconiformes)

The cranial osteology of Micrastur gilvicollis (Vieillot, 1817), Micrastur ruficollis (Vieillot, 1817) and Micrastur semitorquatus (Vieillot, 1817) is comparatively and meticulously described to characterize each of the species and to determine which traits the species have in common and which are distinct. These traits will be used a posteriori for phylogenetic analysis. Our results indicate that M. gilvicollis and M. ruficollis are closely related, as they share a large number of traits, including a lacrimal bone with a distal portion that is approximately half as long as the proximal portion and a parasphenoid rostrum that covers 50% of the distance between the occipital condyle and pterygoid. Similarly, M. gilvicollis and M. semitorquatus both have a partially fused craniofacial flexion zone. In both M. ruficollis and M. semitorquatus, the symphyseal region of the mandible is 1/5 the total length of the mandible. The diagnostic traits for each of these species are as follows: a) in M. gilvicollis, the interorbital distance is 1/3 the length of the parietal, and the zygomatic process stretches 1/5 of the distance from the orbital arch to the jugal arch; b) in M. ruficollis, the interorbital distance is 2/5 of the length of the parietal and the zygomatic process extends 1/4 of the distance from the orbital arch to the jugal arch; and c) in M. semitorquatus, the interorbital distance is 3/7 the length of the parietal and the distal portion of the lacrimal is 1/3 the length of the proximal portion. Among the three species, M. gilvicolis and M. ruficollis share the most traits, which leads us to infer that these species are more closely related to one another than they are to M. semitorquatus. Phylogenetic analysis performed a posteriori may confirm the relationship between these three species.

Changes in Complete Blood Count in Patients With Surgically Treated Facial Fractures

The purpose of this prospective study was to verify the changes in the preoperative and postoperative complete blood counts of patients with surgically treated facial fractures. Fifty consecutive patients with a mean age of 34 years who presented facial fractures and underwent surgical treatment were included. A complete blood count was performed, comprising the red and white blood cell count (cells/mu L), hemoglobin (g/dL), and hematocrit (%) levels. These data were obtained preoperatively and postoperatively during a 6-week period. Statistical analyses were performed using the Kruskal-Wallis and Mann-Whitney tests to identify the possible differences among the groups and among the periods of observation using the Friedman and Wilcoxon matched-pairs signed-ranks tests. The most common location of the fractures was the mandible (42.3%), followed by the zygomatic-orbital (36.5%) and associated locations (21.2%). Leukocytosis was associated with neutrophilia in the immediate postoperative period in all of the groups. There were no values below the reference limits of the values of hemoglobin, hematocrit, and erythrocytes, and no values above the reference limits for the remaining white blood cells, although significant differences among periods were observed in most cells, depending on the type of fracture. The primary findings were leukocytosis associated with neutrophilia, verified in the immediate postoperative period in all of the groups, and the influence of the type of fracture on the significant alterations observed among studied periods on the values of hemoglobin, hematocrit, erythrocytes, leukocytes, neutrophils, and lymphocytes.

Mucocele of the Glands of Blandin-Nuhn After Lingual Frenectomy

Mucoceles are the most common lesions of the minor salivary glands and typically appear as a fluctuant, bluish, nontender, submucosal swelling with a normal overlying mucosa. Mucoceles of the glands of Blandin-Nuhn (in the anterior portion of the ventral surface of the tongue) have been considered to be uncommon. This article reports an unusual case of a large extravasation mucocele involving the ventral surface of the tongue, which appeared after a lingual frenectomy.

Effects of temporal muscle detachment and coronoidotomy on facial growth in young rats

This study analyzed the effects of unilateral detachment of the temporal muscle and coronoidotomy on facial growth in young rats. Thirty one-month-old Wistar rats were distributed into three groups: detachment, coronoidotomy and sham-operated. Under general anesthesia, unilateral detachment of the temporal muscle was performed for the detachment group, unilateral coronoidotomy was performed for the coronoidotomy group, and only surgical access was performed for the sham-operated group. The animals were sacrificed at three months of age. Their soft tissues were removed, and the mandible was disarticulated. Radiographic projections-axial views of the skulls and lateral views of hemimandibles-were taken. Cephalometric evaluations were performed, and the values obtained were submitted to statistical analyses. There was a significant homolateral difference in the length of the premaxilla, height of the mandibular ramus and body, and the length of the mandible in all three groups. However, comparisons among the groups revealed no significant differences between the detachment and coronoidotomy groups for most measurements. It was concluded that both experimental detachment of the temporal muscle and coronoidotomy during the growth period in rats induced asymmetry of the mandible and affected the premaxilla.

Electromyographic Study in Patients With Surgically Treated Facial Fractures

This study, using surface electromyography, analyzed the activity of the masseter muscles of 30 patients with facial bone fractures that were surgically treated. Evaluations were made before surgery and in the 7th, 30th, and 60th days after surgery. The value of each measure and the average of 3 maximum voluntary isometric contractions lasting 5 seconds each were registered, and statistical analyses were performed. Patients had a mean age of 31 years and an average of 1.33 fractures. They were grouped according to the type of fracture as follows: mandibular (50%), zygomatic complex (33%), maxilla (10%), and associated fractures (6.7%). There was a lower masseter activity in the preoperative period, when compared with normal values in all groups of fractures. There was a sharp drop in the masseter activity in the postoperative period of 7 days, and all groups showed recovery of activity in 60 days but still below the normal value referenced in the literature. The mean values of the masseter activity, in descending order, were from the zygomatic complex, mandibular, maxillary, and associated fractures. The unilateral mandibular fractures showed higher values than the bilateral fractures in most of the evaluations. There was a highly significant difference in the comparison of the evolution of the masseter activity on both sides, for mandibular and zygomatic complex fractures, and the pairwise comparison showed significant difference between most groups. It was concluded that facial fractures and surgical procedures had negative effects in the muscle activity as observed using electromyography.

Mandibular Angle Fracture Treated With New Three-Dimensional Grid Miniplate

Fractures of the mandibular angle deserve particular attention because they represent the highest percentage of mandibular fractures and have the highest postsurgical complication rate, making them the most challenging and unpredictable mandibular fractures to treat. Despite the evolution in the treatment of maxillofacial trauma and fixation methods, no single treatment modality has been revealed to be ideal for mandibular angle fractures. Several methods of internal fixation have been studied with great variation in complications rates, especially postoperative infections. Recently, new studies have shown reduction of postsurgical complications rates using three-dimensional plates to treat mandibular angle fractures. Nevertheless, only few surgeons have used this type of plate for the treatment of mandibular angle fractures. The aim of this clinical report was to describe a case of a patient with a mandibular angle fracture treated by an intraoral approach and a three-dimensional rectangular grid miniplate with 4 holes, which was stabilized with monocortical screws. The authors show a follow-up of 8 months, without infection and with occlusal stability.

Using the Condylar Prosthesis After Resection of a Large Odontogenic Myxoma Tumor in the Mandible

Odontogenic myxomas are considered to be a benign odontogenic tumor with locally aggressive behavior. Because these neoplasms are rare in the oral cavity, the possible surgical management can be quite variable. Literature recommendation can vary from simple curettage and peripheral ostectomy to segmental resection. The authors report a case of a 20-year-old patient with an odontogenic myxoma tumor located in the left mandibular angle, ascending ramus, and mandibular symphysis. It was treated by radical resection followed by titanium reconstruction with condylar prosthesis, which allowed rapid return of function with improvement in quality of life and restoration of cosmetic and functional deficits. The lesion did not recur after surgical procedure.
