Spectrum of congenital anomalies in pregnancies with pregestational diabetes.

BACKGROUND: Maternal pregestational diabetes is a well-known risk factor for congenital anomalies. This study analyses the spectrum of congenital anomalies associated with maternal diabetes using data from a large European database for the population-based surveillance of congenital anomalies. METHODS: Data from 18 population-based EUROCAT registries of congenital anomalies in 1990-2005. All malformed cases occurring to mothers with pregestational diabetes (diabetes cases) were compared to all malformed cases in the same registry areas to mothers without diabetes (non-diabetes cases). RESULTS: There were 669 diabetes cases and 92,976 non diabetes cases. Odds ratios in diabetes pregnancies relative to non-diabetes pregnancies comparing each EUROCAT subgroup to all other non-chromosomal anomalies combined showed significantly increased odds ratios for neural tube defects (anencephaly and encephalocele, but not spina bifida) and several subgroups of congenital heart defects. Other subgroups with significantly increased odds ratios were anotia, omphalocele and bilateral renal agenesis. Frequency of hip dislocation was significantly lower among diabetes (odds ratio 0.15, 95% CI 0.05-0.39) than non-diabetes cases. Multiple congenital anomalies were present in 13.6 % of diabetes cases and 6.1 % of non-diabetes cases. The odds ratio for caudal regression sequence was very high (26.40,95% CI 8.98-77.64), but only 17% of all caudal regression cases resulted from a pregnancy with pregestational diabetes. CONCLUSIONS: The increased risk of congenital anomalies in pregnancies with pregestational diabetes is related to specific non-chromosomal congenital anomalies and multiple congenital anomalies and not a general increased risk.

Intratympanic application of an antiviral agent for the treatment of Ménière's disease.

It has been suggested that Ménière's disease is part of a polyganglionitis in which symptoms result from the reactivation of neurotropic virus within the internal auditory canal, and that intratympanic applications of an antiviral agent might be an efficient therapy. In 2002, we performed a pilot study ending with encouraging results. Control of vertigo was achieved in 80% of the 17 patients included. We present here a prospective, double-blind study, with a 2-year follow-up, in 29 patients referred by ENT practitioners for a surgical treatment after failure of a medical therapy. The participation in the study was offered to patients prior to surgery. A solution of ganciclovir 50 mg/ml or of NaCl 9% was delivered for 10 consecutive days via a microwick inserted into the tympanic membrane in the direction of the round window or through a ventilation tube. One patient was withdrawn from the study immediately after the end of the injections. He could not complete the follow-up period, because of persisting vertigo. As he had received the placebo, he was then treated with the solution of ganciclovir. Symptoms persisted and he underwent a vestibular neurectomy. Among the remaining 28 patients, surgery could be postponed in 22 (81%). Surgery remained necessary to control vertigo in 3 patients from the group that received the antiviral agent, and in 3 from the control group. Using an analogical scale, patients of both groups indicated a similar improvement of their health immediately after the intratympanic injections. The scores obtained with a 36-item short-form health survey quality of life questionnaire and the Dizziness Handicap Inventory were also similar for both groups. In conclusion, most patients were improved after the intratympanic injections, but there was no obvious difference between the treated and control groups. The benefit might be due to the middle ear ventilation or reflect an improvement in the patients' emotional state.

Vestibulo-ocular reflex characteristics in patients with unilateral Ménière's disease.

OBJECTIVE: The pathophysiologic concept of Ménière's disease assumes that endolymphatic hydrops is the cause of the symptoms via increased pressure in the endolymphatic space and/or ionic disorder due to ruptured membrane. The goal of this study was to assess whether the vestibulo-ocular reflex (VOR) properties in patients with Ménière's disease were consistent with the classical theory. MATERIAL AND METHODS: We studied 34 patients (19 women, 15 men) presenting with unilateral Ménière's disease divided into 2 groups according to the duration of the disease: 18 were in the early stage (< 12 mo), and 16 were in the late stage (> or = 12 mo). Nineteen patients were examined during an attack. Eight of them and the 15 other patients were tested during the interval between attacks. Their characteristics were compared with those of a group of 22 normal subjects. The VOR function was evaluated via standard caloric and impulse rotatory tests (velocity step). A mathematic model of vestibular function was used to characterize the VOR response to rotational stimulation. Dynamic VOR parameters (sensitivity coefficient, time constant, gain, and asymmetries between the 2 directions of rotation) were statistically compared between the 2 groups of patients during and between attacks and between the patients and controls. RESULTS: All dynamic VOR parameters showed no statistically significant difference both with normal controls and among the patients during and between attacks (p > 0.05) except for gain asymmetry (p < or = 0.008). During attacks, patients with early Ménière's disease displayed a higher gain in rotation toward the affected ear, the opposite being observed in patients with late disease. Caloric test revealed a moderate canal paresis on the affected side during the crisis and a slight asymmetry between attacks. CONCLUSION: During attacks in patients with early Ménière's disease, the VOR gain toward the affected side is higher than that toward the intact side, supporting the fact that that the sensitivity of the cupuloendolymphatic system on the affected ear is increased. This observation is in agreement with a mechanical pressure effect of hydrops on the vestibular organs.

Etude de Nkx5-3, un facteur de transcription impliqué dans le développement de l'oeil

Résumé :Une famille souffrant d'un nouveau syndrome oculo-auriculaire, appelé syndrome de Schorderet-Munier, a été identifiée. Ce syndrome est caractérisé par une déformation du lobe de l'oreille et des anomalies ophtalmiques, notamment une microphtalmie, une cataracte, un colobome et une dégénérescence rétinienne. Le gène impliqué dans ce syndrome est NKX5-3 codant un facteur de transcription contenant un homéodomaine. Chez les patient atteints, le gène comporte une délétion de 26 nucléotides provoquant probablement l'apparition d'un codon stop précoce. Ce gène n'est exprimé que dans certains organes dont les testicules et les ganglions cervicaux supérieurs, ainsi que dans les organes touchés par ce syndrome, à savoir le pavillon de l'oreille et l'oeil, surtout lors du développement embryonnaire. Au niveau de la rétine, NKX5-3 est présent dans la couche nucléaire interne et dans la couche dè cellules ganglionnaires et est exprimé de manière polarisée selon un axe temporal > nasal et ventral > dorsal. Son expression in vitro est régulée par Spl, un facteur de transcription exprimé durant le développement de l'oeil chez la souris. NKX5-3 semble lui-même provoquer une inhibition de l'expression de SHH et de EPHA6. Ces gènes sont tous les deux impliqués à leur manière dans le guidage des axones des cellules ganglionnaires de la rétine. Pris ensemble, ces résultats nous permettent donc d'émettre une hypothèse quant à un rôle potentiel de NKX5-3 dans ce processus.Abstract :A family with a new oculo-auricular syndrome, called syndrome of Schorderet-Munier, was identified. This disease is characterised by a deformation of the ear lobule and by several ophthalmic abnormalities, like microphthalmia, cataract, coloboma and a retinal degeneration. The gene, which causes this syndrome, is NKX5-3 coding for a transcription factor contaning a homeodomain. In the affectd patients, the defect consists of a deletion of 26 nucleotides probably producing a premature stop codon. This gene is only expressed in a few organs like testis and superior cervical ganglions, as well as in organs affected by this syndrome, namely the ear pinna and the eye, mainly during embryonic development. In the retina, NKX5-3 is present in the inner nuclear layer and in the ganglion cells layer. It is expressed along a gradient ranging from the temporal retina to nasal retina and from the ventral to the dorsal part. Its in vitro expression is regulated by Spl, a transcription factor expressed during the murine eye development. NKX5-3 seems to inhibit the expression of SHH and EPHA6. These genes are both implicated, in their own way, in the axon guidance of the retinal ganglion cells. Taken together, these results allow us to make an assumption about a potential role of NKX5-3 in this process.

Multiple Epiphyseal Dysplasia, Recessive.

Disease characteristics. Recessive multiple epiphyseal dysplasia (EDM4/rMED) is characterized by joint pain (usually in the hips or knees); malformations of hands, feet, and knees; and scoliosis. Approximately 50% of affected individuals have some abnormal finding at birth, e.g., clubfoot, clinodactyly, or (rarely) cystic ear swelling. Onset of articular pain is variable but usually occurs in late childhood. Stature is usually within the normal range prior to puberty; in adulthood, stature is only slightly diminished and ranges from 150 to 180 cm. Functional disability is mild. Diagnosis/testing. Diagnosis of EDM4/rMED is based on clinical and radiographic findings. SLC26A2 is the only gene known to be associated with EDM4/rMED. Molecular genetic testing is available on a clinical basis. Management. Treatment of manifestations: physiotherapy for muscular strengthening; cautious use of analgesic medications such as nonsteroidal anti-inflammatory drugs (NSAIDs); orthopedic surgery as indicated. Surveillance: radiographs as indicated. Agents/circumstances to avoid: sports involving joint overload. Genetic counseling. EDM4/rMED is inherited in an autosomal recessive manner. At conception, each sib of a proband with EDM4/rMED has a 25% chance of being affected, a 50% chance of being an asymptomatic carrier, and a 25% chance of being unaffected and not a carrier. Once an at-risk sib is known to be unaffected, the risk of his/her being a carrier is 2/3. Carrier testing for at-risk relatives and prenatal testing for pregnancies at increased risk is possible if both disease-causing alleles in the family are known and the carrier status of the parents has been confirmed. Requests for prenatal testing for mild conditions such as EDM4/rMED are not common.

L'ostéolyse expansive familiale : manifestations otologiques et dentaires d'origine génétique

RESUME Nous rapportons l'étude d'une famille de 49 membres sur 5 générations. Parmi 35 membres étudiés, 18 sont atteints d'Osteolyse Expansive Familiale (OEF). L'OEF est une dysplasie osseuse génétique rare, autosomique dominante, dont les altérations locales et générales du squelette ont une distribution périphérique prédominante qui devient manifeste à partir de la deuxième décennie de vie. Une résorption ostéoclastique progressive, accompagnée d'une faible activité ostéoblastique, est à l'origine d'une expansion médullaire osseuse. Cette dernière est caractérisée par une raréfaction de la moelle osseuse qui est remplacée par du tissu fibreux et de la graisse. L'amincissement de la moelle osseuse aboutit à des déformations invalidantes, sévères et douloureuses du squelette, avec tendance aux fractures spontanées. La première manifestation clinique de la maladie est une surdité de transmission très précoce résultant d'une lyse de la chaîne ossiculaire. Radiologiquement, il existe toujours une pneumatisation marquée de la mastoïde et du rocher. Les dents montrent des signes importants de résorption osseuse au niveau de la région apicale et/ou du collet, dont l'aspect est caractéristique et unique. La phosphatase alcaline sérique, l'hydroxyproline et la deoxypiridoline urinaire sont élevées à des taux variables. Le taux de calcium et d'hormone parathyroïdienne est normal. Le traitement par les diphosphonates, la calcitonine et la vitamine D est inefficace. Histologiquement, l'OEF présente des similitudes avec la maladie de Paget, mais l'âge de début, la distribution des lésions osseuses, les altérations dentaires et de l'oreille moyenne, ainsi que la progression clinique sont différents. Il en va de même pour la dysplasie fibreuse, l'ostéite fibro-kystique et l'ostéogénèse imparfaite. Le gêne responsable de la maladie se localise dans la région du chromosome 18q21-22. Récemment, des mutations du TNFRSF 11A, gêne qui codifie le RANK, ont été identifiées comme étant la cause de l'OEF. La duplication de la 18ème paire de base au niveau de l'exon 1 suggère qu'il correspond au site de l'anomalie. La technique chirurgicale et les résultats audiométriques à court et long terme de 13 interventions chez 8 patients sont présentés. ABSTRACT Objectives: Familial Expansive Osteolysis (EEO) is a rare autosomal dominant bone dys¬plasia. The disease can show general and focal skeletal alterations, the latter having a pre¬dominantly peripheral distribution. Onset occurs after the second decade of life. Patients and methods: We present the study, of 30 years, of a family consisting of 49 members covering five generations. Results: Among the 35 members studied, 18 have familial expansive osteolysis (FEO). The first clinical sign of the condition is transmission deafness at an early age. The features of the teeth has a unique and characteristic appearance. Thinning of the corti¬cal bone leads to severe, painful, disabling deformities. Serum alkaline phosphatase, and urinary hydroxyproline and deoxipyridinoline are elevated. Calcium and parathyroid hor¬mone are normal. Treatment with diphosphonates, calcitonin and vitamin D has been unsuccessful. We present the surgical technology and the results to short and long term of 13 interventions on 8 patients. Conclusion: Progressive osteoclastic reabsorption accompanied by weak osteoblastic activ¬ity results in medullary expansion characterized by rarefaction of the bone marrow, which is replaced by fibrous tissue and fat. FE0 is histologically similar to Paget disease, but the age of onset, the distribution of the bone lesions, the dental and middle ear alterations, and the clin¬ical progression are different. These features also differentiate FE0 from fibrous dysplasia, fibrocystic osteitis and imperfect osteogenesis. The gene responsible for EEO is located in the 18q21-22 chromosome region. Mutations in TNFRSF11A, the gene encoding receptor activa¬tor of nuclear factor-kappa-B (RANK), has been recently identified as the cause of FEO. A duplication of 18 base pairs in exon 1 of the TNFRSF11A gene suggests that this corresponds to the site of the anomaly and can be considered a "hot spot" for mutations.

The temporoparietal fascia flap: a versatile tool in head and neck reconstruction.

PURPOSE OF REVIEW: The article reviews recent significant advances and current applications of the temporoparietal fascia flap (TPFF) in head and neck surgery. RECENT FINDINGS: The recent literature describes a wide span of new applications of the TPFF in many areas. Significant developments and refinements in the reconstruction of orbitomaxillary composite defects and orbital exenteration cavities are reported. The TPFF combined with alloplastic framework is gaining in importance in external ear reconstruction. Innovative prefabricated skin or soft-tissue grafts based on the TPFF are used to restore facial contour or in the reconstruction of complex facial defects. The free TPFF finds a role in laryngotracheal reconstruction as a vascular carrier to support cartilage grafts. SUMMARY: Owing to its reliability and unequalled structural properties, the TPFF still plays a central role in facial reconstruction. Future investigation will likely incorporate the free TPFF as a vascular carrier of bioengineered tissues, such as cartilage and mucosa, for various head and neck indications.

Place du frottis cytologique à l'adolescence [Role of the PAP smear in adolescence]

The publication of the 2006 directives concerning the management of PAP smears has incited us to update our internal protocols at the CHUV, which are described in this article. A new addition to these directives is the specific management of adolescent PAP smears, who present both a high HPV carriage rate and increased incidence of cytological abnormalities with a favorable outcome in most cases. Our goal is to avoid over-treating dysplasias in this type of patient in order to avoid long-term complications. Emphasis is placed on the first gynecological consultation where a listening ear and clear and targeted information remain essential in the proper management of a young patient.

The role of neutrophils upon leishmania major infection

Les neutrophiles constituent la première ligne de défense contre un grand nombre de pathogènes. Après infection avec Leishmania major, les neutrophiles migrent rapidement et massivement au site d'infection par le parasite. Les neutrophiles sont d'importants acteurs dans l'orchestration de la réponse anti-Leishmania, via la sécrétion de nombreuses cytokines, chimiokines et composés stockés dans leurs granules. De plus, les neutrophiles interagissent avec les cellules présentatrices d'antigènes, telles que les cellules dendritiques et en conséquences contribuent au développement de la réponse adaptative. A ce jour, l'impact des neutrophiles sur 1'activation des cellules dendritiques et les possibles conséquences de l'interaction neutrophiles avec ces dernières sur l'évolution de la maladie suite à l'infection avec L. major reste peu connu. Ainsi, nous avons dans un premier temps investigué l'influence des neutrophiles sur 1'activation des cellules dendritiques in vitro. Suite à cela, nous avons analysé le rôle des neutrophiles sur 1'activation des cellules dendritiques présentes au site d'infection et dans les ganglions drainants in vivo, après inoculation intra-dermale de L. major dans le pavillon auriculaire de souris de souche C57BL/6 et BALB/c, ainsi que les conséquences de la déplétion des neutrophiles sur l'évolution de la maladie. Nous avons pu démontrer que les neutrophiles ont un impact négatif sur l'activation des cellules dendritiques exposées à L. major in vitro, via des mécanismes impliquant la sécrétion de Prostaglandines par les neutrophiles et la séquestration des parasites. La déplétion des neutrophiles dans les souris BALB/c durant les premiers jours après infection avec L. major dans le derme de l'oreille résulte en une augmentation de l'expression de marqueurs d'activation des cellules dendritiques présentes dans les ganglions drainants, mais pas au site d'infection. De plus, les souris BALB/c transitoirement déplétées en neutrophiles développent des lésions significativement plus petites, une réponse de type Th2 diminuée et une charge parasitaire plus faible au site d'infection que les souris non déplétées. La déplétion des neutrophiles dans les souris C57BL/6 n'a pas d'influence détectable sur l'activation des cellules dendritiques que ce soit au niveau des ganglions drainants ou au site d'infection. La progression de la lésion et la charge parasitaire ne sont pas affectées par la déplétion des neutrophiles, malgré le développement d'une réponse Th2 diminuée par rapport aux souris non déplétées. En résumé, dans les premières heures après infection, les neutrophiles ont un effet négatif sur l'activation des cellules dendritiques et sur la réponse anti-Leishmania dans les souris BALB/c tandis que leur rôle paraît moins important dans les souris C57BL/6. Ces résultats peuvent avoir d'importantes implications en terme de développement de nouveaux vaccins contre Leishmania. - Neutrophils constitute the first line of defense against a variety of pathogens. Following Leihmania major infection neutrophils migrate rapidly and massively to the site of parasite inoculation. They are important players in the orchestration of the anti-leishmania response through the release of a plethora of cytokines, chemokines and granular components. In addition, neutrophils interact with antigen-presenting cells such as dendritic cells (DCs) and thereby contribute to the development of the adaptive immune response. However, the impact of neutrophils on the activation of DCs and possible consequences on disease progression following L. major infection are poorly understood. Therefore, we first investigated the influence of neutrophils on DC activation in vitro. Next we analyzed the role of neutrophils on the activation of DCs present at the site of infection and in the draining lymph node (dLN) following inoculation of L. major in the ear pinna of C57BL/6 and BALB/c mice and analyzed the consequences of early neutrophil depletion on disease progression. We could demonstrate that neutrophils had a negative impact on the activation of DCs exposed to L. major in vitro through mechanisms involving neutrophil-derived prostaglandins and sequestration of parasites. In BALB/c mice, depletion of neutrophils during the first days of infection with L. major in the ear dermis increased the expression of activation markers on dLN DCs but not on DCs present at the site of infection. In addition, BALB/c mice transiently depleted of neutrophils developed significantly smaller lesions, a decreased Th2 immune response and harbored fewer parasites at the site of infection compared to non-depleted littermates. In C57BL/6, mice early depletion of neutrophils had no detectable impact on the activation of DCs both at the site of infection and in the dLN following L. major inoculation. Furthermore, depletion of neutrophils had no major effect on lesion evolution and parasite loads despite the development of a decreased Th2 immune response compared to non- depleted littermates. In summary, at the onset of infection, neutrophils are detrimental for DC activation and the anti-leishmania response in BALB/c mice while their role appears to be less important in C57BL/6 mice. These findings could have important implications for the design of new vaccination strategies.

High expression of the HMG box factor sox-13 in arterial walls during embryonic development.

Members of the Sox gene family of transcription factors are defined by the presence of an 80 amino acid homology domain, the High Mobility Group (HMG) box. Here we report the cloning and initial analysis of murine Sox-13 . The 984 amino acids Sox-13 protein contains a single HMG box, a leucine zipper motif and a glutamine-rich stretch. These characteristics are shared with another member of the Sox gene family, Sox-6. High level embryonic expression of Sox-13 occurs uniquely in the arterial walls of 13.5 days post coitum (dpc) mice and later. Low level expression was observed in the inner ear of 13.5 dpc mice and in a limited number of cells in the thymus of 16.5 dpc mice, from which Sox-13 was originally cloned. At 18.5 dpc, Sox-13 is expressed in the tracheal epithelium below the vocal cord and in the hair follicles. The Sox-13 protein binds to the consensus HMG box motif, AACAAAG, but does not transactivate transcription through a concatamer of this motif. Sox-13, like other members of the Sox family likely plays an important role in development.

Auditory localisation and recognition after left inferior collicular lesion: effects of work load on cortical activation patterns (fMRI study)

Evidence from neuropsychological and activation studies (Clarke et al., 2oo0, Maeder et al., 2000) suggests that sound recognitionand localisation are processed by two anatomically and functionally distinct cortical networks. We report here on a case of a patientthat had an interruption of auditory information and we show: i) the effects of this interruption on cortical auditory processing; ii)the effect of the workload on activation pattern.A 36 year old man suffered from a small left mesencephalic haemotrhage, due to cavernous angioma; the let% inferior colliculuswas resected in the surgical approach of the vascular malformation. In the acute stage, the patient complained of auditoryhallucinations and of auditory loss in right ear, while tonal audiometry was normal. At 12 months, auditory recognition, auditorylocalisation (assessed by lTD and IID cues) and auditory motion perception were normal (Clarke et al., 2000), while verbal dichoticlistening was deficient on the right side.Sound recognition and sound localisation activation patterns were investigated with fMRI, using a passive and an activeparadigm. In normal subjects, distinct cortical networks were involved in sound recognition and localisation, both in passive andactive paradigm (Maeder et al., 2OOOa, 2000b).Passive listening of environmental and spatial stimuli as compared to rest strongly activated right auditory cortex, but failed toactivate left primary auditory cortex. The specialised networks for sound recognition and localisation could not be visual&d onthe right and only minimally on the left convexity. A very different activation pattern was obtained in the active condition wherea motor response was required. Workload not only increased the activation of the right auditory cortex, but also allowed theactivation of the left primary auditory cortex. The specialised networks for sound recognition and localisation were almostcompletely present in both hemispheres.These results show that increasing the workload can i) help to recruit cortical region in the auditory deafferented hemisphere;and ii) lead to processing auditory information within specific cortical networks.References:Clarke et al.

Mutation in the human homeobox gene NKX5-3 causes an oculo-auricular syndrome.

Several dysmorphic syndromes affect the development of both the eye and the ear, but only a few are restricted to the eye and the external ear. We describe a developmental defect affecting the eye and the external ear in three members of a consanguineous family. This syndrome is characterized by ophthalmic anomalies (microcornea, microphthalmia, anterior-segment dysgenesis, cataract, coloboma of various parts of the eye, abnormalities of the retinal pigment epithelium, and rod-cone dystrophy) and a particular cleft ear lobule. Linkage analysis and mutation screening revealed in the first exon of the NKX5-3 gene a homozygous 26 nucleotide deletion, generating a truncating protein that lacked the complete homeodomain. Morpholino knockdown expression of the zebrafish nkx5-3 induced microphthalmia and disorganization of the developing retina, thus confirming that this gene represents an additional member implicated in axial patterning of the retina.

Horizontal vestibulo-ocular reflex dynamics in acute vestibular neuritis and viral labyrinthitis: evidence of otolith-canal interaction.

OBJECTIVE: To evaluate the dynamic properties of the horizontal vestibulo-ocular reflex (h-VOR) in the acute stage of two common labyrinthine diseases that provoke severe attacks of vertigo with spontaneous nystagmus: vestibular neuritis (vestibular loss alone) and viral labyrinthitis (cochleovestibular loss). MATERIAL AND METHODS: Sixty-three patients were investigated: 42 were diagnosed with vestibular neuritis and 21 with viral labyrinthitis. The h-VOR function was evaluated by conventional caloric and impulsive testing. A simplified model of vestibular function was used to analyze the vestibulo-ocular response to rotational stimulation. RESULTS: The results showed a significant difference in h-VOR characteristics between the two pathologies. Patients with vestibular neuritis exhibited a strong horizontal semicircular canal deficit, but no h-VOR asymmetry between the two rotational directions. In contrast, patients with viral labyrinthitis demonstrated moderate canal paresis and a marked h-VOR deficit in rotation toward the affected ear. CONCLUSION: These findings support the hypothesis that the h-VOR dynamic asymmetry that occurs after an acute unilateral inner ear lesion is not due to canal dysfunction alone, but involves complex adaptive changes in the central VOR that may implicate the otolith system. Based on histopathologic and clinical differences in the two pathologies reported in the literature, we postulate that this otolith-canal interaction is mainly linked to the loss of saccular function.

Body taping for contour surgery.

BACKGROUND: Preoperative marking is of primary importance in body contouring and when precise simulation of skin excisions is difficult. Because the "cut as you go" principle can be delicate, especially in patients after massive weight loss, a simple and quick method is needed for preoperative planning. We suggest an approach that helps visualize the optimal skin incision lines and simulates the postoperative result by body taping. METHODS: Twelve patients who underwent abdominal contouring, including classic and vertical abdominoplasties as well as dog ear and scar revision, were prospectively analyzed. The skin to be excised was preoperatively folded, taped, and then marked. The area marked was measured and compared with the actual intraoperatively resected area and the postoperative result was evaluated after 1 year by the patients and three surgeons. RESULTS: With body taping, an 83% congruence between the preoperative planning and the surgery was obtained and only two patients had additional skin resected. No wound dehiscence and flap necrosis occurred and patients as well as surgeons scored the final body contour positively. CONCLUSION: Body taping is a simple, quick, and economic method for planning contour surgery with high accuracy as demonstrated by the low rate of intraoperative changes of the planned resection and low complication rate.

Prevalence, prenatal diagnosis and clinical features of oculo-auriculo-vertebral spectrum: a registry-based study in Europe.

Oculo-auriculo-vertebral spectrum is a complex developmental disorder characterised mainly by anomalies of the ear, hemifacial microsomia, epibulbar dermoids and vertebral anomalies. The aetiology is largely unknown, and the epidemiological data are limited and inconsistent. We present the largest population-based epidemiological study to date, using data provided by the large network of congenital anomalies registries in Europe. The study population included infants diagnosed with oculo-auriculo-vertebral spectrum during the 1990-2009 period from 34 registries active in 16 European countries. Of the 355 infants diagnosed with oculo-auriculo-vertebral spectrum, there were 95.8% (340/355) live born, 0.8% (3/355) fetal deaths, 3.4% (12/355) terminations of pregnancy for fetal anomaly and 1.5% (5/340) neonatal deaths. In 18.9%, there was prenatal detection of anomaly/anomalies associated with oculo-auriculo-vertebral spectrum, 69.7% were diagnosed at birth, 3.9% in the first week of life and 6.1% within 1 year of life. Microtia (88.8%), hemifacial microsomia (49.0%) and ear tags (44.4%) were the most frequent anomalies, followed by atresia/stenosis of external auditory canal (25.1%), diverse vertebral (24.3%) and eye (24.3%) anomalies. There was a high rate (69.5%) of associated anomalies of other organs/systems. The most common were congenital heart defects present in 27.8% of patients. The prevalence of oculo-auriculo-vertebral spectrum, defined as microtia/ear anomalies and at least one major characteristic anomaly, was 3.8 per 100,000 births. Twinning, assisted reproductive techniques and maternal pre-pregnancy diabetes were confirmed as risk factors. The high rate of different associated anomalies points to the need of performing an early ultrasound screening in all infants born with this disorder.
