Surgical Correction of Aesthetically Deformed Eyebrows Using Local Transposition Flaps

Eyebrow positions differ in many ways. They vary in shape, thickness, length, and distance between the eyebrows, making the face more or less harmonious. When a large distance exists between the eyebrows and the medial brow is slanting downward, the glabellar area is larger, giving the face an awkward appearance. To correct this deformity, the authors propose using two Z-plasties to allow transposition of flaps in the region of the medial brow. The Z-shaped flap is outlined at the medial third of the brow, in the glabellar region, with the eyebrow centered in the lower portion of the ""Z"" and the hairless skin in the upper portion. The flaps then are transposed and sutured. Transposition of the flaps, lifting the brow flap to the glabellar region, results in horizontal positioning of the medial and central third of the eyebrow. The proposed transpositioning of ""Z"" flaps in this region corrects this type of deformity of the medial and central portions of the eyebrows, with an aesthetically satisfactory result.

Combination micrografting and tattooing in the reconstruction of eyebrows of patients with craniofacial clefts

The absence of an eyebrow, either partial or total, has been observed in patients with craniofacial clefts, such as the Tessier 9 to 13 cleft. Several techniques have been used to improve the appearance of the region, such as island scalp flaps and scalp strip grafting, with limited or marginally satisfactory aesthetic results. The authors report 2 patients with craniofacial clefts in whom a novel technique combining 2 separate surgical approaches, micrografting and tattooing, was used. The use of micrografting with single or double hair units, properly angulated, produces natural-looking and satisfactory results with a minimum of morbidity. Excellent volume and appearance of the eyebrow may be achieved in a single session using this technique. Tattooing performed subsequently over the microimplanted hairs provides the illusion of greater density to the eyebrow, resulting in an appearance closer to normal.

Outbreak of Mycobacterium haemophilum infections after permanent makeup of the eyebrows.

We report a Mycobacterium haemophilum outbreak after permanent make-up of the eyebrows performed by the same freelance artist. Twelve patients presented an eyebrow lesion and cervical lymphadenitis. All were treated with antibiotics. Surgery was required in 10 cases. M. haemophilum DNA was identified in the make-up ink.

Bazex-Dupre-Christol syndrome in a 1-year-old boy and his mother

Bazex - Dupre - Christol syndrome is a rare genodermatosis with cancer predisposition, characterized by follicular atrophoderma, multiple milia, congenital hypotrichosis, hypohidrosis and basal cell malformations that include nevoid basal cell carcinomas of early onset. We present two patients with this syndrome, a 1-year-old boy with diffuse scalp and eyebrows alopecia, milia papules on the face, ears, trunk, and limbs. Hypohidrosis was observed on his trunk and head. His 16-year-old mother had identical changes since childhood, with hair fragility, and multiple atrophic ""ice pick"" follicular depressions on the dorsa of her hands. She also had a basal cell carcinoma on her face. Microscopic examination of hairs from the mother revealed abnormalities such as diameter irregularities, broken shafts, trichorrexis nodosa and pili bifurcatti. Pili bifurcatti is an uncommon hair shaft dysplasia that has not before been observed in Bazex - Dupre - Christol syndrome.

Clinical manifestations in patients with SOS1 mutations range from Noonan syndrome to CFC syndrome.

Noonan syndrome (NS) and cardio-facio-cutaneous (CFC) syndrome are autosomal dominant disorders characterized by heart defects, facial dysmorphism, ectodermal abnormalities, and mental retardation. There is a significant clinical overlap between NS and CFC syndrome, but ectodermal abnormalities and mental retardation are more frequent in CFC syndrome. Mutations in PTPN11 and KRAS have been identified in patients with NS and those in KRAS, BRAF and MAP2K1/2 have been identified in patients with CFC syndrome, establishing a new role of the RAS/MAPK pathway in human development. Recently, mutations in the son of sevenless gene (SOS1) have also been identified in patients with NS. To clarify the clinical spectrum of patients with SOS1 mutations, we analyzed 24 patients with NS, including 3 patients in a three-generation family, and 30 patients with CFC syndrome without PTPN11, KRAS, HRAS, BRAF, and MAP2K1/2 (MEK1/2) mutations. We identified two SOS1 mutations in four NS patients, including three patients in the above-mentioned three-generation family. In the patients with a CFC phenotype, three mutations, including a novel three amino-acid insertion, were identified in one CFC patient and two patients with both NS and CFC phenotypes. These three patients exhibited ectodermal abnormalities, such as curly hair, sparse eyebrows, and dry skin, and two of them showed mental retardation. Our results suggest that patients with SOS1 mutations range from NS to CFC syndrome.

3-M syndrome associated with growth hormone deficiency: 18 year follow-up of a patient.

3-M syndrome is a rare autosomal recessive disorder that causes short stature, unusual facial features and skeletal abnormalities. Mutations in the CUL7, OBSL1 and CCDC8 genes could be responsible for 3-M syndrome.Here we describe the growth and evolution of dismorphic features of an Italian boy with 3-M syndrome and growth hormone deficiency (GHD) from birth until adulthood. He was born full term with a very low birth weight (2400 g=-3.36 standard deviation score, SDS) and length (40.0 cm =-6.53 SDS). At birth he presented with a broad, fleshy nose with anteverted nostrils, thick and patulous lips, a square chin, curvilinear shaped eyebrows without synophrys, short thorax and long slender bones. Then, during childhood tall vertebral bodies, hip dislocation, transverse chest groove, winged scapulae and hyperextensible joints became more evident and the diagnosis of 3-M syndrome was made; this was also confirmed by the finding of a homozygous deletion in exon 18 of the CUL7 gene, which has not been previously described.The patient also exhibited severe GHD (GH <5 ng/ml) and from the age of 18 months was treated with rhGH. Notwithstanding the early start of therapy and good compliance, his growth rate was always very low, except for the first two years of treatment and he achieved a final height of 132 cm (-6.42 SDS).

Fourteen new cases contribute to the characterization of the 7q11.23 microduplication syndrome.

Interstitial deletions of 7q11.23 cause Williams-Beuren syndrome, one of the best characterized microdeletion syndromes. The clinical phenotype associated with the reciprocal duplication however is not well defined, though speech delay is often mentioned. We present 14 new 7q11.23 patients with the reciprocal duplication of the Williams-Beuren syndrome critical region, nine familial and five de novo. These were identified by either array-based MLPA or by array-CGH/oligonucleotide analysis in a series of patients with idiopathic mental retardation with an estimated population frequency of 1:13,000-1:20,000. Variable speech delay is a constant finding in our patient group, confirming previous reports. Cognitive abilities range from normal to moderate mental retardation. The association with autism is present in five patients and in one father who also carries the duplication. There is an increased incidence of hypotonia and congenital anomalies: heart defects (PDA), diaphragmatic hernia, cryptorchidism and non-specific brain abnormalities on MRI. Specific dysmorphic features were noted in our patients, including a short philtrum, thin lips and straight eyebrows. Our patient collection demonstrates that the 7q11.23 microduplication not only causes language delay, but is also associated with congenital anomalies and a recognizable face.

Prediction of difficult intubation with advanced face recognition techniques: a preliminary study

Introduction: Difficult tracheal intubation remains a constant and significant source of morbidity and mortality in anaesthetic practice. Insufficient airway assessment in the preoperative period continues to be a major cause of unanticipated difficult intubation. Although many risk factors have already been identified, preoperative airway evaluation is not always regarded as a standard procedure and the respective weight of each risk factor remains unclear. Moreover the predictive scores available are not sensitive, moderately specific and often operator-dependant. In order to improve the preoperative detection of patients at risk for difficult intubation, we developed a system for automated and objective evaluation of morphologic criteria of the face and neck using video recordings and advanced techniques borrowed from face recognition. Method and results: Frontal video sequences were recorded in 5 healthy volunteers. During the video recording, subjects were requested to perform maximal flexion-extension of the neck and to open wide the mouth with tongue pulled out. A robust and real-time face tracking system was then applied, allowing to automatically identify and map a grid of 55 control points on the face, which were tracked during head motion. These points located important features of the face, such as the eyebrows, the nose, the contours of the eyes and mouth, and the external contours, including the chin. Moreover, based on this face tracking, the orientation of the head could also be estimated at each frame of the video sequence. Thus, we could infer for each frame the pitch angle of the head pose (related to the vertical rotation of the head) and obtain the degree of head extension. Morphological criteria used in the most frequent cited predictive scores were also extracted, such as mouth opening, degree of visibility of the uvula or thyreo-mental distance. Discussion and conclusion: Preliminary results suggest the high feasibility of the technique. The next step will be the application of the same automated and objective evaluation to patients who will undergo tracheal intubation. The difficulties related to intubation will be then correlated to the biometric characteristics of the patients. The objective in mind is to analyze the biometrics data with artificial intelligence algorithms to build a highly sensitive and specific predictive test.

MLL2 mutation detection in 86 patients with Kabuki syndrome: a genotype-phenotype study.

Recently, pathogenic variants in the MLL2 gene were identified as the most common cause of Kabuki (Niikawa-Kuroki) syndrome (MIM#147920). To further elucidate the genotype-phenotype correlation, we studied a large cohort of 86 clinically defined patients with Kabuki syndrome (KS) for mutations in MLL2. All patients were assessed using a standardized phenotype list and all were scored using a newly developed clinical score list for KS (MLL2-Kabuki score 0-10). Sequencing of the full coding region and intron-exon boundaries of MLL2 identified a total of 45 likely pathogenic mutations (52%): 31 nonsense, 10 missense and four splice-site mutations, 34 of which were novel. In five additional patients, novel, i.e. non-dbSNP132 variants of clinically unknown relevance, were identified. Patients with likely pathogenic nonsense or missense MLL2 mutations were usually more severely affected (median 'MLL2-Kabuki score' of 6) as compared to the patients without MLL2 mutations (median 'MLL2-Kabuki score' of 5), a significant difference (p < 0.0014). Several typical facial features such as large dysplastic ears, arched eyebrows with sparse lateral third, blue sclerae, a flat nasal tip with a broad nasal root, and a thin upper and a full lower lip were observed more often in mutation positive patients.

Interdisciplinary approach to treat dyskeratosis congenita associated with severe aplastic anemia: A case report

This paper reports on a 4-year-old male who had dyskeratosis congenita and who acquired severe aplastic anemia. The patient developed hyperpigmentation of the face, neck and chest region, arms, shoulders and legs. In addition, he had dry skin, deformed fingernails and toenails, sparse hair and eyebrows and hyperkeratosis of the dorsum of the hands and feet. Laboratory and histological analysis revealed severe pancytopenia and dyserythropoiesis of red blood cells, hypocellularity of white blood cells and decreased megakaryocytes with dysplasia. The intraoral examination identified bleeding gums; petechiae of the palate, tongue and cheek mucosa; and an atrophic, smooth and shining dorsal surface of the tongue. There were deep carious lesions in the deciduous mandibular molars and maxillary anterior teeth; as well as mobility of mandibular left canine, which had bone loss. The treatment for oral lesions included diet changes, improved oral hygiene, and extraction of the deciduous teeth destroyed by caries.

Assessment of eyebrow position before and after upper eyelid blepharoplasty

Objective: Assess the occurrence of secondary brow ptosis after upper lid blepharoplasty. Methods: Forty-five individuals (n90 brows) submitted to upper lid blepharoplasty, were assessed by means of a comparative analysis using pre- and post-operatively digital photographs, in the primary position of the eye. The images were processed using ImageJ software, transferred to a computer, to an electronic Microsoft Excel 2002® worksheet. Angular measurements were used, taking the lateral canthal angle of the brow, the most medial point of the brow, the medial canthal angle and the lateral canthal angle of the lid as anatomical reference points. When the outer angles were reduced or the inner angles increased after surgery this was considered a brow ptosis. Individuals who had undergone lid surgery associated with the eyebrow, previous eyebrow surgery and those with eyelid ptosis were excluded. The difference between the pre-operative and post-operative measurements were analyzed statistically using the Student's t-test for paired samples and the angular variation was compared with their corresponding contralateral sample using Wilcoxon's non-parametric test. Results: The measurements obtained after the blepharoplasty show significant variations from those before the surgery, indicating that the correction of redundant tissues in the brow accentuates the tendency of the eyebrow to move down. The alterations are more important in the lateral portion of the eyebrow and they occur bilaterally. Conclusion: The assessment of angular measurements obtained pre- and post-operatively showed that there are secondary changes in the position of the eyebrow as a result of upper eyelid blepharoplasty. © 2012 Informa Healthcare USA, Inc.

Displasia ectodérmica hipohidrótica: un síndrome de interés para la odontología

Hypohidrotic ectodermal dysplasia (HED) is a rare disease of genetic etiology. The most frequent form is of recessive linked to X-chromosome inheritance with affected male and female carriers. It can occur through autosomal mutations, of the gene EDA1 gene being responsible for the majority of the cases. It is characterized by the triad: hypohidrosis, oligodontia and hypotrichosis. We present two cases of patients with HED in which we observed characteristic signs of this syndrome: delicate skin, sparce hair, eyebrows and eyelashes, periorbital wrinkles, perioral and periorbital hyperpigmentation, prominent lips, in addition the patient in case 2 also present the depressed nasal bridge. We also found decreased salivary and lacrimal secretion and maxillary hypoplasia in both cases. At the oral examination in case 1 the upper right and left deciduous canines and lower right deciduous canine were present, and in case 2 the upper and lower (right and left) deciduous canines and two upper (one right and other left) permanent incisors were present with altered morphology, all of these dental elements were healthy. The early dental treatment of patients with HED, especially in the presence of oligodontia, as observed in our cases, is important not only to provide a better quality of life for these patients in the short term, but also an attempt to minimize the changes in facial growth to which these patients are subject.

Analysis of MLL2 gene in the first Brazilian family with Kabuki syndrome

Most patients with Kabuki syndrome (KS) are the only person in their family with the condition. However, familial cases of KS have been described showing evidence that this syndrome can be inherited as a dominant trait with variable expressivity. We report on two related individuals with facial findings characteristic of KS. The proposita had arched eyebrows, long and upward slanting palpebral fissures, cleft lip and palate, retromicrognathia, brachydactyly of hands and feet, stubby fingers, nail hypoplasia, and prominent finger pads. Her mother had eyebrows with dispersed lateral half, long and upward slanting palpebral fissures, retrognathia, abnormal and posteriorly rotated ears, prominent finger pads, brachydactyly of feet, learning difficulties, and psychomotor development delay. DNA sequencing revealed a novel missense mutation in the MLL2 gene in both the proposita and her mother. The mutation (p.R5432Q) was found in the exon 51, within the SET domain of the gene, which confers methyltransferase activity on the protein. Therefore, the epigenetic and transcriptional regulatory properties of this protein may be altered and this suggests that the mutation is the cause of phenotype observed in both the patient and her mother. The clinical signs and the molecular evidence in this family further support the notion that KS is an autosomal dominant condition with variable expressivity. To our knowledge this is the first report of a Brazilian family with recurrence of this syndrome. (C) 2012 Wiley Periodicals, Inc.
