Complicações da blefaroplastia superior

The blepharoplasty has been performed with great frequency due to the appreciation of aesthetic surgery. The complications related to this procedure are rare. This case report aims to emphasize complications that can occur. T.J.S.P., 45 years old, female, white, resident of Botucatu City, presented dermatocalase bilaterally. We opted to perform upper blepharoplasty bilateral, by removing skin and fat of the upper eyelid. In the postoperative period was observed left eyelid ptosis. We decided to reinsert the levator muscle of the left upper eyelid. One month after the ptosis correction, retraction was observed in both upper eyelid. The patient was then submitted to surgery for the correction of eyelid retraction by disinsertion of the muscle of Muller. Two months after this last surgery, the patient presented right eyelid ptosis and worsening of eyelid retraction to the left. New surgery for correction of the eyelid retraction was made, using free graft sclera for elongation of the left eyelid levator muscle, with good results.The authors presented a patient who underwent a blepharoplasty and developed ptosis in the post-operative period, followed by eyelid retraction. These two possibilities may occur as a complication of blepharoplasty and the surgeon must be careful to handle in an appropriate way, in order to get the result that the patient expects to have.

Fifteen-year Follow-up of a Conservatively Managed, Root-fractured Permanent Incisor

The purpose of this case report was to describe the successful long-term conservative management of a root-fractured permanent maxillary right central incisor in an 8-year-old patient. After the initial approach of splinting the traumatized tooth, the patient was followed on a regular basis for 15 years. Clinically, the crown of the root-fractured incisor showed no displacement or discoloration, and thermal tests suggested pulp vitality over the follow-up period. Radiographically, an increase in the diastasis was observed between the apical and coronal fragments due to both the growth of the alveolar process and the healing with interposition of hard and soft tissue between the fragments and confirmed with computed tomography scan in the 15-year follow-up appointment.

Development, characterization and clinical use of a biodegradable composite scaffold for bone engineering in oro-maxillo-facial surgery

We have developed a biodegradable composite scaffold for bone tissue engineering applications with a pore size and interconnecting macroporosity similar to those of human trabecular bone. The scaffold is fabricated by a process of particle leaching and phase inversion from poly(lactide-co-glycolide) (PLGA) and two calcium phosphate (CaP) phases both of which are resorbable by osteoclasts; the first a particulate within the polymer structure and the second a thin ubiquitous coating. The 3-5 mu m thick osteoconductive surface CaP abrogates the putative foreign body giant cell response to the underlying polymer, while the internal CaP phase provides dimensional stability in an otherwise highly compliant structure. The scaffold may be used as a biomaterial alone, as a carrier for cells or a three-phase drug delivery device. Due to the highly interconnected macroporosity ranging from 81% to 91%, with macropores of 0.8 similar to 1.8 mm, and an ability to wick up blood, the scaffold acts as both a clot-retention device and an osteoconductive support for host bone growth. As a cell delivery vehicle, the scaffold can be first seeded with human mesenchymal cells which can then contribute to bone formation in orthotopic implantation sites, as we show in immune-compromised animal hosts. We have also employed this scaffold in both lithomorph and particulate forms in human patients to maintain alveolar bone height following tooth extraction, and augment alveolar bone height through standard sinus lift approaches. We provide a clinical case report of both of these applications; and we show that the scaffold served to regenerate sufficient bone tissue in the wound site to provide a sound foundation for dental implant placement. At the time of writing, such implants have been in occlusal function for periods of up to 3 years in sites regenerated through the use of the scaffold.

Squamous cell carcinoma in a residual mandibular cyst

Described is a case of squamous-cell carcinoma arising in a residual cyst in a 60-year-old edentulous woman. The clinical and radiographic diagnosis was residual cyst, and the treatment employed was conservative surgical enucleation. The cause of these changes is unknown. Theoretically, the inflammatory reaction may have been a predisposing factor.

Spondylothoracic dysplasia in two siblings

The spondylothoracic dysplasia syndrome is characterized by congenital malformations of vertebrae and ribs. As a consequence of the anomalous development of the vertebral column, the neck and thorax are short, and the normal head looks as if emerging from the shoulders. The thorax is short and asymmetric with an increased anteroposterior diameter. Dorsolumbar lordosis and a protuberant abdomen are present. The extremities though normal in length appear long relative to the shortened trunk. Short stature results from the vertebral abnormalities. The syndrome was seen in 2 siblings of nonconsanguineous parents.

Meningeoma do ventrículo lateral em jovem

A case of intraventricular meningioma in a 17 year old white man located in the right lateral ventricle is presented. The tumor was successfully removed at operation, and weighed 470 grams. The patient made a good recovery; however, hemiparesis and amaurosis amaurosis, remained.

Cell-mediated and humoral immunity in West syndrome

The immunological status of five children with West syndrome consequent to previous cerebral lesions was investigated. Three children had West syndrome and two were in transition from West to Lennox-Gastaut syndrome. All of them showed cellular immunological deficiencies in the following tests: sensitization to DNCB, intracutaneous reaction to PHA, inhibition of leukocyte migration, blastic transformation of lymphocytes, T and B lymphocytes in peripheral blood and levels of serum immunoglobulins. These immunological deficiencies, of different degrees of severity, were associated with frequent infections in these children. A possible association between the immunological deficiencies and autoimmunity is discussed.

FG syndrome in a Brazilian child with additional previously unreported signs.

We report on a Brazilian child with typical manifestations of the FG syndrome. Pigmentary dysplasia, metacarpal fusion and peculiar anatomopathological findings are additional undescribed signs.

Paracoccidioidomycosis: study of six cases with ocular involvement

We present 6 patients with ocular involvement due to paracoccidioidomycosis. All cases were confirmed by the finding of Paracoccidioides brasiliensis in histopathological or direct mycologic examination of material from the lesion in the eyelid or conjunctiva. In two cases the bulbar conjunctiva was also involved, in another the cornea, and still another patient developed endophthalmitis. The presence of this mutilating disease which may lead to blindness should be suspected when chronic blepharitis or palpebral ulcerated papular lesions are detected in patients from endemic areas of paracoccidioidomycosis. This etiology should also be suspected in patients with anterior and posterior uveitis after discarding the most frequent causes of this condition. © 1988 Kluwer Academic Publishers.
