RESUMO
INTRODUCTION: The incidence of congenital nevi is one over 20,000 newborns per year, 14 % of them are located in the head and neck area. Nevi of the orbital region are particularly difficult to handle on the aesthetic and functional side. The objectives of this study were to conduct an analysis of different clinical presentations of congenital nevi of the eyelid orbital region in children to establish a treatment algorithm. MATERIEL AND METHODS: We realised a bi-centric retrospective study including 51 children with orbito-palpebral congenital nevi. We analysed the different clinical presentations, their treatments and their results. RESULTS: Nineteen underwent direct suture excision; three a total skin graft; 15 a combination of treatments, among them four underwent tissular expansion and 14 patients were not operated and clinically followed-up. The average follow-up time was 6.6 years. In 33 cases residual nevic area was still present. The postoperative sequelae were: dyschromia (n=17), anatomical deformation of the eye (n=10), nevi outbreaks (n=8), internal canthus deformation (n=5) and ectropion (n=1). CONCLUSION: The results of our study show that therapeutic abstention is preferred when the aesthetic wrong is accepted by the patient and when there is not a higher risk of malignant degeneration. In order to minimise the risk of postoperative sequelae, we propose a therapeutic algorithm for the management of congenital orbital nevi.

UNLABELLED: Surgical management of giant melanotic naevi remains a surgical challenge. Tissue expansion provides tissue of the same quality for the repair of defects. The aim of this study is to review tissular expansion for giant melanotic naevi. MATERIALS AND METHODS: We conducted a retrospective study from 2000 to 2012. All children patients who underwent a tissular expansion for giant congenital naevi had been included. Epidemiological data, surgical procedure, complication rate and results had been analysed. RESULTS: Thirty-tree patients had been included; they underwent 61 procedures with 79 tissular-expansion prosthesis. Previous surgery, mostly simple excision had been performed before tissular expansion. Complete naevus excision had been performed in 63.3% of the cases. Complications occurred in 45% of the cases, however in 50% of them were minor. Iterative surgery increased the complication rate. CONCLUSION: Tissular expansion is a valuable option for giant congenital naevus. However, complication rate remained high, especially when iterative surgery is needed.

OBJECTIVE: To report a clinical case of acute otitis media in a child, complicated by septic temporomandibular arthritis and to present a review of the literature. PATIENT AND METHODS: We report a case of a 7-year-old boy who presented an altered general condition, major hyperthermia, associated with a left temporozygomatic mass in a context of recurrent bilateral acute otitis media lasting for 2 months. Emergency computed tomodensitometry (CT scan) showed left temporomandibular joint arthritis. Treatment consisted of a parenteral double antibiotic therapy and prevention of temporomandibula (TM) ankylosis. RESULTS: After 20 months of follow-up, the child showed a normal ORL examination with no maxillofacial sequelae. CONCLUSION: All temporozygomatic masses presenting in a septic context should suggest the diagnosis of TM arthritis; computed tomodensitometry should be done immediately.

Performing a conventional Z-plasty on postburn scar tissue frequently leads to varying degrees of necrosis of the tips of the transposed flaps. In the conventional technique, the flaps are transposed first by anchoring the tips and then by performing the other sutures. In this order, the tips are subjected to a high degree of tension. Again, according to the conventional technique, perpendicular incisions are performed along the tips, which do not ensure the effective vascularisation of the tips in this context of postburn scarring tissue with loss of dermal blood flow. Two technical modifications are proposed: a different approach to the tension by first of all anchoring the base of the flaps and not by classical first suturing of the tips and the performance of oblique incisions away from the tips to ensure a maximum vascularisation of the subdermal fatty tissue. These two elements have allowed us to improve the results of our plasties.

A two-year-old boy was referred for correction of an amputation of penis following ritual circumcision. The reconstruction involved mobilization of the profound part of corpora cavernosa and coverage by a vascularised flap taken from the hypogastric area through the use of a sub-cutaneous expandable prosthesis. After two years, appearance of the neo-penis is satisfactory considering the initial lesions.

Capsular contracture constitutes the main postoperative complication after breast augmentation by implant placement. To date, no systemic treatment known allows for improvement that does not simultaneously put the patient at risk for secondary complications of a more general nature. Flector Tissugel is the sole locally active antiinflammatory patch. Its durable local antiinflammatory effect is associated only with a risk for rare and highly limited side effects. After approximately 3 weeks of treatment, a high frequency of change from capsular contracture Baker 2 or 3 to Baker 1 occurs, provided the application was started no later than 3 months after the onset of capsular contracture.

The fractional resurfacing (Fraxel laser) is a new procedure for facial and extrafacial rejuvenation. His claim is obtain a great efficacy on wrinkles, close to those of the CO(2) and erbium lasers, but without their risks and long lasting down time. We use a scanner, able to create multiple (around 2000 to 3000/cm(2)) 70-150 microns diameter microthermal zones surrounded by islands of viable tissue. The reepithelialization is complete in a day, but there is a collagen denaturization in the dermis, between 300-750 microns like after a traditional resurfacing. At each session, around 25% of the dermis are treated. 4 treatments are performed with a 1 to 2 weeks interval. We report our comprehensive results since we began in December 2004. At the time of the abstract, 600 sessions were performed (150 Patients). A visible reduction of wrinkles is observed anytime, with improvement of the texture of the skin, and in the same time, a dramatic improvement of the pigmented lesions. About tolerance, no severe side effects or dyschromia were noticed. We observed two case of limited erosion, (one of the first patients) due to a practical problem (bulk heating). The average erythema duration is 2 days. On the face, a 2-4 days edema occurs in many of the patients. Fraxel laser treatment is not designed as a substitute for surgical skin tightening such as facelift. Therefore, the fractional resurfacing is safe and effective for a visible reduction of wrinkles and appears as a very interesting treatment in association with face lift to rejuvenate the face.

Cell ageing is responsible for the increasingly creased appearance of our skin. The ageing of the structures of the face is attributed primarily to the effect of gravity on the tissues. The theory expounded below sets out to prove that the main and initial cause of this ageing is the repeated contractions of the mimic muscles. This concept attributes only a secondary role to gravity in the ageing process, which is initially brought about by muscular contractions. An MRI study recently made it possible to demonstrate the anterior convexity curve of the mimic muscles in the young subject. This curve is due to the existence at the back of these muscles of a deep fat pad. In the young subject, the extent of its convexity and its location give a specific, youthful character to the movements, in terms of direction and amplitude, of the facial muscles. With age, the muscle gradually straightens and shortens due to the repeated contractions that expel the underlying fat and increase the tonus at rest. The application of these new findings to the ageing of the face gives rise to new technical possibilities both in the field of medicine and aesthetic surgery. These new techniques have the same targets: segments of the mimic muscles (maintain over time a good muscular curve and a low tonus at rest) and the underlying fatty convexities. As far as medicine is concerned, the combination of botulinum toxin and filling has proved its worth. But two technical elements are new: the filling products must, at several points, be injected primarily behind the muscle to treat the depressions naturally and restore the initial curve of the overlying muscle. A very low number of units (a quarter to one unit) of botulinum toxin must be injected into certain muscles to diminish the tonus at rest of these muscles without diminishing their strength in maximum contraction. In surgery, new possibilities to treat premature ageing include procedures that combine segmentary muscular weakening, micro liposuctions and retromuscular reinjections. The advantage with regard to the medical procedures is greater stability over time and the greater precision of these muscular actions (one third of a muscle can be weakened for example) and the fat reinjections can be more stable. These procedures can be performed under local anesthesia. In cases of more advanced ageing, surgery offers new treatment possibilities that include, for the midface region, the concentric malar lift. It replaces, on the orbital rim, the sub-orbicularis oculi fat that has descended eccentrically as a result of the contractions of the orbicularis oculi muscle. The procedure, using the subperiosteal detachment plane, is therefore stable over time. At the same time, specific muscles are weakened. The aims of restoring fatty volumes and muscular tonuses are thus achieved. Similarly, in the neck, the platysma muscle is specifically weakened. Each area is studied in line with its specificities. For the first time, the skin tension of the facelift has no more to be maximum to treat the relief of the jawl line, of the palpebro malar groove and so on. The skin tension becomes moderate, just to remove the excess of skin. The relief is faded with the specific muscular and fatty action. The name of this new concept is Face Recurve.

Surgical treatment of the lesions of the scalp in children has specific objectives: excision of an extensive lesion using minimum operative procedures, hiding scar in the hair, correcting a wide and ungraceful scar. We reviewed our experience of 450 cases (1990-2000), and found that most common lesions in childhood were: sebaceous hamartoma, pigmentary naevus, post traumatic alopecia, aplasia cutis congenita and complicated hemangiomas. Different surgical procedures are discussed: excision, tissue expansion, hair grafts. Large excision can be performed before three months of life because of the good laxity of the scalp. Tissue expansion is particularly suited to the scalp. Aplasia cutis congenita is a special condition, with local vascular abnormalities: local flaps are prohibited. Hemangiomas may require early surgical treatment in the event of complications.

The ultrastructure of KB cells infected with oncogenic adenovirus 12 was studied at various intervals from 4 to 72 hr after viral inoculation. At 12 hr after infection, the nucleus and the nucleolus became hypertrophic. At 16 hr, bundles of fibers digestable by proteolytic enzymes were seen in the nucleus; they are considered as the early viral antigens identified immunologically by others. Between 24 and 26 hr, four types of nuclear inclusions appeared. Their sequence of appearance and fine structure are described. On the basis of their sensitivity to proteolytic digestion in thin sections, and the results of immunoferritin studies made by others, some of these inclusions are believed to represent viral structural antigens. Throughout the cycle of viral replication, the nucleolus displayed prominent and constant changes in the form of focal condensations and loosening of the nucleolonema, followed by atrophy and fragmentation. It is suggested that the early nucleolar changes reflect an active participation of the nucleolus in the synthesis of adenovirus 12. A hitherto unknown striated structure with definite periodicity, which is easily digested by proteolytic enzymes, was found in the nuclei during the late stages of adenovirus 12 replication.

Twenty-three patients with hyperparathyroidism from six families with the multiple endocrine adenomatosis (MEA) I-syndrome were tested by secretin provocation. In nine cases this led to increases in serum gastrin ranging from 298 to 13 300 pg/ml, whereas the maximum rise in gastrin in the other 14 patients was 32 pg/ml. In all nine patients with marked gastrin responses to secretin, the Zollinger-Ellison syndrome was diagnosed by gastric acid hypersecretion and large increases in gastrin after calcium administration. Six of these nine patients had, at most, minor postprandial rises in gastin and two had demonstrable tumors. In 34 normal subjects, 23 nonaffected members of families with MEA I-syndrome, and 42 patients with various diseases the maximum gastrin response to secretin was 21 pg/ml. We conclude that secretin provocation is helpful in the diagnosis of the Zollinger-Ellison syndrome, especially when basal serum gastrin levels are only slightly elevated.

OBJECTIVE: Presentation of a specific surgical technique of vertical alveolar ridge distraction performed on an alveolar bone graft 1 year after the primary grafting procedure designed to correct a labioalveolar cleft. The graft had not obtained the results desired and presented heavily scarred mucosal tissue. TECHNIQUE: A dental implant placed within the graft once it has been entirely freed by osteotomies functions as an endless screw. To avoid vascular risk, the alveolar bone graft is detached as a whole along its total height. Consequently, no bone remains above it to provide support for a conventional alveolar distractor. An osteosynthetic miniplate, fastened in a horizontal position beneath the nasal mucosae above the graft, is used to replace the missing bony support and to stabilize the implant, which activates the distraction process. PATIENT: This study is based on our first clinical case with a follow-up of 18 months at present. RESULT: A vertical displacement of the entire graft was achieved, including its attached mucosal layer, which repositioned both bone and mucosa on a far better level in the cleft area. Thus, a normal length of abutment was obtained permitting prosthetic rehabilitation based on the same endosseous implant, which was left in place within the graft. CONCLUSION: This technique may prove particularly helpful in certain cases in which a primary alveolar bone grafting procedure has produced borderline results. In such cases, on the one hand, neither the reasonably satisfactory volume of the bone graft itself nor the poor quality of its scarred mucosal tissue argue in favor of a secondary grafting procedure. On the other hand, it is impossible to resort to currently available alveolar distracters since our choice of techniques leaves no bone support above the graft.

BACKGROUND: The natural course of immature hemangiomas in infants is well-known. A rapid phase of growth from 6 to 8 months is followed by a period of stability then regression. Since approximately 70% of these immature hemangiomas resolve spontaneously, abstention is generally the rule. The volume or localization of certain lesions may nevertheless have a serious functional or morphological impact. MATERIAL AND METHODS: This retrospective study included 81 children who underwent surgery between October 1994 and March 2000. The children were aged 2 to 38 months at the time of surgery. Orbital localizations predominated (33 children). The indication for surgery was based on two criteria: risk of a functional impairment or risk of morphological sequela. All children with orbital hemangiomas with a functional risk of amblyopia were initially treated with corticosteroids. Surgery was performed in case of failure. The CAVITRON was used for 77 children and DISSECTRON for 4. These two ultrasound devices allowed easy dissection with little hemorrhage. RESULTS: There were no peroperative hemorrhagic complications. Few postoperative complications were observed. After resection of the orbital hemangiomas there was little functional impact and the postoperative ophthalmologic examinations were normal within several weeks. Mean follow-up was 12 months after surgery. Use of an ultrasound dissector allowed early and safe treatment of immature hemangiomas. DISCUSSION: Certain voluminous or poorly localized hemangiomas, particularly on the face, can have a serious function, morphological or psychological impact. Medical treatment is not always active and surgical resection may be required before the development of definitive sequelae. Ultrasound dissection, not previously used in this indication, can contribute significantly to the surgical outcome as demonstrated in these children operated on early. This technique is safe and shortens operative time. In light of these results, we believe early resection of immature hemangiomas should be reevaluated. It should not be considered as a last resort but rather as a complementary treatment.

In children, mandibular swelling associated with an X-ray bone osteolysis may correspond to tumoral or infection diseases. Circumscribed osteitis of a child's mandibula, with no dental etiology occurs around 7-years of age, adjacent to a healthy first molar. Five cases reports were analyzed. Clinically, it is a bone swelling of the mandibula's lateral cortical associated with a soft tissue swelling. X-ray signs were not specific but all cases showed a bone lacuna with sharp outlines. Such clinical and X-ray signs strongly suggest diagnosis of osteitis which has a higher incidence than malignant tumors. The lack of dental pathology suggests bloodstream dissemination from another localized sepsis. Surgical removal of pathologic bone in addition to antibiotics (6 or 8 weeks) appears to be an effective treatment.

To determine if immunity to human cytomegalovirus (HCMV) protects women from acquiring HCMV from their children, a blinded, randomized protocol was used to monitor seronegative women who received placebo or Towne vaccine (approximately 500 pfu) and seropositive women. Each group was similar for mean maternal (33 years) and child age (18 months) and duration of viral shedding by the child (15 months). Among 19 placebo recipients, 9 developed primary infection; 8 of 19 vaccines but only 3 of 42 naturally seropositive subjects had evidence of acquiring HCMV from their child. Wild type infection and Towne vaccine induced similar mean lymphoproliferative responses to HCMV antigens, but one dose of Towne vaccine produced mean neutralizing titers 10- to 20-fold lower than those after wild type infection. Thus, a vaccine that induces immune responses equal to those induced by wild type virus may protect healthy women from acquiring HCMV from their children.
