Sample records for 1400-km cleft ion

  1. Quiet-time plasma irregularities at 1400 km in the cleft region

    1978-01-01

    The quiet north polar cleft at 1400 km was studied by Isis-2 instruments, and data from the retarding potential analyzer and the cylindrical electrostatic probe show that thermal plasma density fluctuations are distributed in a region between 75 deg and 82 deg invariant latitude and approximately dawn to dusk. Cleft shape and shape variations are described. Thermal ions and thermal electrons usually fluctuated together, but suprathermal electrons fluctuated independently. Data on thermal plasma patterns correlates fairly well with observations of soft particles and auroral optical emissions and not as well with measurements of high-energy particles. The data suggest that the energy source for the thermal irregularities is associated with soft particles and that precipitating high-energy particles do not drive the thermal plasma at these altitudes.

    1997-01-01

    Bulk parameters for the thermal ions (0.3 to 25 eV) have been derived using data from the Scanning Thermal Ion Composition Spectrometer (STICS) on the Sounding of the Cleft Ion Fountain Energization Region (SCIFER) experiment. The SCIFER rocket was launched into the ionospheric cleft region at 1000 MLT with a maximum altitude of 1450 km. The heated cleft plasma was observed to be H(+) dominated, in sharp contrast with observations of the same region near solar maximum. Regions of particular interest include the sharp, heated equatorward wall of the cleft and highly structured patches of transversely-accelerated ions (TAI). Densities, temperatures and velocities are used to characterize and distinguish these regions and to compare to predicted bulk parameters from candidate heating mechanisms.

  4. The cleft ion fountain - A two-dimensional kinetic model

    Horwitz, J. L.; Lockwood, M.

    1985-01-01

    The transport of ionospheric ions from a source in the polar cleft ionosphere through the polar magnetosphere is investigated using a two-dimensional, kinetic, trajectory-based code. The transport model includes the effects of gravitation, longitudinal magnetic gradient force, convection electric fields, and parallel electric fields. Individual ion trajectories as well as distribution functions and resulting bulk parameters of density, parallel average energy, and parallel flux for a presumed cleft ionosphere source distribution are presented for various conditions to illustrate parametrically the dependences on source energies, convection electric field strengths, ion masses, and parallel electric field strengths. The essential features of the model are consistent with the concept of a cleft-based ion fountain supplying ionospheric ions to the polar magnetosphere, and the resulting plasma distributions and parameters are in general agreement with recent low-energy ion measurements from the DE 1 satellite.

  5. TIDE Observations of Cusp and Cleft Multiple Ion Populations

    2000-01-01

    The southern pole pass of Polar/TIDe at 5000 km allows a study of the distributions of the cusp and cleft. We discuss observations of TIDE (Thermal Ion Dynamics Experiment) as it passes the southern pole on March 29, 1999. A mixture of several cold outflowing ions (0.3-10 eV) are measured simultaneously with magnetospheric precipitation (greater than 100 eV). We will show a study of these multiple plasma distributions, their source, and their interaction.

  6. Rapid Kinematic and Tectonic Variations Along the 1400-km-long Australia-Woodlark Plate Boundary Zone, Papua New Guinea and Woodlark Basin

    NASA Astrophysics Data System (ADS)

    Mann, P.; Taylor, F. W.; Gahagan, L.; Watson, L.

    2004-12-01

    Previous GPS studies have shown the wide variability in present-day plate motions across the highly arcuate, 1400-km-long Australia-Woodlark plate boundary extending from Papua New Guinea to the Solomon Islands. GPS-determined motions range from orthogonal oceanic spreading in the Woodlark basin, to continental transtension in the 2.5-km-high core complex area of easternmost Papua New Guinea, to continental strike-slip and transpression in 4-km-high mountains of the Papuan Peninsula. We use imagery, earthquake focal mechanisms, coral reef uplift data, and structural mapping studies to establish the along-strike continuity of the active plate boundary fault. Systematic angular changes in the direction of the plate vector along this continuous fault explain its varied tectonic geomorphology, Holocene uplift history, and geologic structure. We use a series of plate reconstructions to illustrate the longer term, Cenozoic evolution of this boundary including: its formation as an arcuate, N- and NE-dipping ophiolitic suture zone during Paleogene time, the progressive "unzippering" of this thrust over the past 6 Ma along a N- and NE-dipping, low-angle normal fault in easternmost Papua New Guinea, and its "zippering" or continued shortening on the suture thrust in the Owen Stanley Ranges of the Papuan Peninsula. Over the 1400-km-length of the fault, the length of segments of oceanic spreading, transtension, and transpression is 250-500 km; the time period separating one tectonic style from the succeeding style encroaching from the east is several million years. This systematic spatial and temporal superposition of tectonic styles, leads to complex - but predictable - along-strike variations in geologic history.

  7. Strong ambipolar-driven ion upflow within the cleft ion fountain during low geomagnetic activity

    We investigate low-energy (<10 eV) ion upflows (mainly O+) within the cleft ion fountain (CIF) using conjunctions of the Enhanced Polar Outflow Probe (e-POP) satellite, the DMSP F16 satellite, the SuperDARN radar, and the Resolute Bay Incoherent Scatter Radar North (RISR-N). The SEI instrument on board e-POP enables us to derive ion upflow velocities from the 2-D images of ion distribution functions with a frame rate of 100 images per second, and with a velocity resolution of the order of 25 m/s. We identify three cleft ion fountain events with very intense (>1.6 km/s) ion upflow velocities near 1000 km altitude during quiet geomagnetic activity (Kp < 3). Such large ion upflow velocities have been reported previously at or below 1000 km, but only during active periods. Analysis of the core ion distribution images allows us to demonstrate that the ion temperature within the CIF does not rise by more than 0.3 eV relative to background values, which is consistent with RISR-N observations in the F region. The presence of soft electron precipitation seen by DMSP and lack of significant ion heating indicate that the ion upflows we observe near 1000 km altitude are primarily driven by ambipolar electric fields. DC field-aligned currents (FACs) and convection velocity gradients accompany these events. The strongest ion upflows are associated with downward current regions, which is consistent with some (although not all) previously published results. The moderate correlation coefficient (0.51) between upflow velocities and currents implies that FACs serve as indirect energy inputs to the ion upflow process.

  8. Storm Enhanced Density (SED) plumes as possible suppliers of dayside cleft ion fountain

    NASA Astrophysics Data System (ADS)

    Horwitz, James

    Foster et al. [2002] have observed elevated ionospheric density regions being convected from the subauroral plasmaspheric region toward noon, in association with convection of plasmaspheric tails in the dayside magnetosphere. These so-called Storm Enhanced Density (SED) regions could serve as ionospheric plasma source populations for cleft ion fountain outflows. Here we examine this scenario and employ our fluid-kinetic ionospheric plasma transport code to simulate the entry of a high-density "plasmasphere-like" flux tube entering the cleft region and subjected to an episode of wave-driven transverse ion heating. We find that such pronounced intervals of SED at F-region and topside altitudes passing through regions of CIF processes indeed appear capable of supporting episodes of strong CIF outflows.

    Foster et al. [2002] reported elevated ionospheric density regions convected from subauroral plasmaspheric regions toward noon, in association with convection of plasmaspheric tails. These Storm Enhanced Density (SED) regions could supply cleft ion fountain outflows. Here, we will utilize our Dynamic Fluid Kinetic (DyFK) model to simulate the entry of a high-density ``plasmasphere-like'' flux tube entering the cleft region and subjected to an episode of wave-driven transverse ion heating. It is found that the O^+ ion density at higher altitudes increases and the density at lower altitudes decreases, following this heating episode, indicating increased fluxes of O^+ ions from the ionospheric source gain sufficient energy to reach higher altitudes after the effects of transverse wave heating.

  10. Distribution in magnetotail of O(+) ions from cusp/cleft ionosphere - A possible substorm trigger

    NASA Technical Reports Server (NTRS)

    Cladis, J. B.; Francis, W. E.

    1992-01-01

    The transport of O(+) ions from the cusp/cleft ionosphere to the magnetotail during highly disturbed times was determined by computing the guiding-center trajectories of the ions to a distance of 6 R(E) from the ionosphere and the full-motion trajectories at later times. Case histories were tallied in six planes perpendicular to the X(GSM) axis, three planes perpendicular to the Y(GSM) axis, and in the center plane of the tail. At various times relative to the enhancement of the convection electric field, the following ion properties were constructed from the case histories: number density, mean energy, energy and pitch angle distributions of the flux, and ion pressure components parallel and perpendicular to the magnetic field. It was found that, after about 1.7 hours, the ion flux in the near-earth magnetotail increased dramatically and the spectrum hardened, much as observed during periods just preceding substorms. This increase is attributed to (1) the increase in the O(+) outflux from the ionosphere, (2) the increased energization of the ions by the convection electric field, and (3) ion trapping, which generally occurs because the ion magnetic moments generally increase after the ions first cross the geomagnetotail center plane.

    1992-01-01

    The transport of O{sup +} ions from the cusp/cleft ionosphere to the magnetotail during highly disturbed times was determined by computing the guiding-center trajectories of the ions to a distance of 6 R{sub E} from the ionosphere and the full-motion trajectories at later times. Case histories were tallied in six planes perpendicular to the X{sub GSM} axis, three planes perpendicular to the Y{sub GSM} axis, and in the center plane of the tail. At various times relatives to the enhancement of the convection electric field, the following ion properties were constructed from the case histories; number density, mean energy, energy and pitch angle distributions of the flux, and ion pressure components parallel and perpendicular to the magnetic field. It was found that after about 1.7 hours the ion flux in the near-Earth magnetotail increased dramatically and the spectrum hardened, much as observed during periods just preceding substorms. This increase is attributed to (1) the increase in the O{sup +} outflux from the ionosphere, (2) the increased energization of the ions by the convection electric field, and (3) ion trapping, which generally occurs because the ion magnetic generally increase after the ions first cross the geomagnetotail center plane. Moreover, the parallel pressure of the ions exceeds the energy density of the magnetic field at X{sub GSM} < {minus}8 R{sub E}. On the basis of the expected alterations of the magnetic and electric fields in response to this O{sup +} pressure, a substorm trigger mechanism is suggested.

  12. Observations of Multi - Component Ion Beams in the High-Altitude Cusp/Cleft Region

    NASA Astrophysics Data System (ADS)

    Koleva, R.; Semkova, J.; Smirnov, V.; Fedorov, A.

    Both Solar wind and the Earth ionosphere serve as sources of magnetospheric plasma. Having entered (SW ions) or being ejected (ionospheric ions) into the magnetosphere, ions are involved in the magnetospheric circulation. The common idea is that ions, convected to the lobe region, due to the ExB drift, enter the region of the plasma sheet and get energized by different processes. Magnetospheric plasma flows have been widely investigated, using mainly energy-per-charge measurements. While this method successfully differentiates ion species, which have near - equal flow speed and low thermal velocities [e.g. Seki et al., J. Geophys. Res., 1998], the ionic composition of hot magnetospheric flows could only be revealed in mass or mass-per-charge measurements. Recent plasma flows studies based on ion composition measurements [Lennartson, J. Geophys. Res., 2001] showed a great deal of similarity between the tailward drifts of the different ions, especially in the transition region between the central plasma sheet and the tail lobes, and evoked the idea of near-Earth mixing of the Solar wind and ionospheric ions. We present some experimental evidence on near-Earth mixing of magnetospheric ions of different origin. Used are data from the Low Energy Plasma Composition Experiment (AMEI-2) onboard the high-apogee INTERBALL-1 satellite. We present and discuss several cases of ion beams with energies above 3 keV, registered in the cusp/cleft region at distances from 5 to 9 Re, in which both He++ and O+ are present. The beams are observed on filed lines connected with different magnetospheric regions: the LLBL, the plasma mantle and the lobe. The energy/pitch angle behaviour of both He++ (Solar wind origin) and O+ (ionospheric origin) reveals great similarity, as if they are from one and the same source. Only the wider distributions of the He++ fluxes and the narrow ones of the O+ ions indicate their different origin. The distributions bare the signatures of various acceleration

    1997-01-01

    This study examines high-latitude ion outflows and velocities perpendicular to the magnetic field derived from moments of ion distributions measured by the TIDE (Thermal Ion Dynamics Experiment) instrument on the Polar satellite. Hydrogen and oxygen ions are shown to be E X B drifting in the polar cap and cleft regions with a speed of about 5-20 km/s at apogee (approximately 9 Re) and a speed of 1-2 km/s at perigee (approximately 1. 8 Re). E X B drifts are calculated from electric fields measured by EFI (Electric Field Instrument) and magnetic fields measured by MFE (Magnetic Field Experiment) both of which are also on Polar. How convection at Polar's perigee relates to potential patterns of the ionosphere will be discussed. In the cusp/cleft the distribution of hydrogen extends over a large enough range of energy to be measured by both TIDE and the Toroidal Imaging Mass-Angle Spectrograph (TIMAS). Such comparisons will be also be presented.

    Elevated ionospheric density regions frequently appear to be convected from the subauroral plasmaspheric region toward noon, in association with convection of plasmaspheric tails in the dayside magnetosphere, typically during large geomagnetic storms. In this presentation, we explore the possibility that these Storm Enhanced Density (SED) regions could provide ionospheric plasma source populations for cleft ion fountain outflows. We use our Dynamic Fluid Kinetic (DyFK) code to simulate the entry of a high-density "plasmasphere-like" flux tube entering the cleft region and subjected to an episode of wave-driven transverse ion heating. The results of including different proportions of SED and soft electron precipitation levels, together with transverse ion heating effects on the resulting outflows, will be presented, including the O+ and H+ ion density and related parameter profiles for the simulated SED involved events. We will also compare these modeling results with SED-outflow observations from GPS TEC, and the FAST and IMAGE spacecraft. Foster, J. C., P. J. Erickson, A. J. Coster, J. Goldstein, and F. J.

    The paper describes absolute ion concentration measurements with an ion mass spectrometer on the Isis 2 satellite and discusses features of the ion composition near a fixed altitude of 1400 km as they relate to longitudinal and latitudinal variations at low and middle latitudes. Two distinct classes of daytime ionospheric behavior are observed. The data obtained confirm the strong solar-geomagnetic seasonal control over the topside ion distribution. The new phenomena associated with the observed longitudinal dependence of the ion composition at 1400 km demonstrate the existence of complex physical processes which take place in this region of the ionosphere.

    Cleft lip with or without cleft palate is the most common congenital malformation of the head and neck. Orofacial clefting could significantly affect the quality of life of the child and requires multiple steps of care to obtain an optimal outcome. Each patient should be evaluated for congenital anomalies, developmental delay, neurologic disorders, and psychosocial concerns. A multidisciplinary team is necessary to ensure that every aspect of the child's care is appropriately treated and coordination between providers is achieved.

  19. Ion mass spectrometer experiment for ISIS-2 spacecraft

    Hoffman, John H.

    1987-01-01

    The International Satellite for Ionospheric Studies (ISIS) program of NASA was the longest duration program in NASA history. A number of satellites were flown under this program, the last being called ISIS-2, which was launched on April 1, 1971 and operated successfully for over 13 years. An experiment called the Ion Mass Spectrometer (IMS) was flown on the ISIS-2 spacecraft. It operated for 10 years providing a large data base of positive ion composition and ion flow velocities along the orbit of the satellite, the latter being circular at 1400 km with a 90 degree inclination.

    Mishra, Sobhan; Sabhlok, Samrat; Panda, Pankaj Kumar; Khatri, Isha

    2015-12-01

    Median or midline facial clefts are rare anomalies of developmental origin, etiology of whose occurrence is still unknown precisely. The most basic presentation of midline facial clefts is in the form of a Median cleft lip which is defined as any congenital vertical cleft through the centre of the upper lip. First described by Bechard in 1823, it is the most common amongst all atypical clefts reported. The incidence is about 1:10,00,000 births. This may occur as a sporadic event or as a part of an inherited sequence of anomalies. It arises embryologically from incomplete fusion of the medial nasal prominences. The authors present a series of eight cases with varying degrees of midline facial clefts. This review article aims to give a broad idea on the various classifications used for further understanding of midline facial clefts and a brief idea about the various surgical management techniques used in the repair of these facial clefts.

    Branchial cleft cyst, sinuses, and fistulae are among the most commonly encountered congenital anomalies in pediatric otolaryngic practice. They can present difficulty in diagnosis and surgical management. Here, I report a case of 14-year-old boy who presented with asymptomatic, congenital swelling located just below the jawline in the lateral part of the neck. The lesion was excised surgically. Histopathology showed the cyst lined by squamous as well as columnar ciliated epithelium, which was a characteristic finding of branchial cleft cyst. The aim of presenting this case is its rarity.

    Intermediate and definitive cleft rhinoplasties are a challenging part of definitive cleft care. The anatomy of the cleft nose is severely affected by the structural deficits associated with congenital orofacial clefting. A comprehensive understanding of the related anatomy is crucial for understanding how to improve the appearance and function in patients with secondary cleft nasal deformities. Timing of intermediate and definitive rhinoplasty should be carefully considered. A thorough understanding of advanced rhinoplasty techniques is an important part of providing adequate care for patients with these deformities.

    Orofacial clefts are common birth defects and can occur as isolated, nonsyndromic events or as part of Mendelian syndromes. There is substantial phenotypic diversity in individuals with these birth defects and their family members: from subclinical phenotypes to associated syndromic features that is mirrored by the many genes that contribute to the etiology of these disorders. Identification of these genes and loci has been the result of decades of research using multiple genetic approaches. Significant progress has been made recently due to advances in sequencing and genotyping technologies, primarily through the use of whole exome sequencing and genome-wide association studies. Future progress will hinge on identifying functional variants, investigation of pathway and other interactions, and inclusion of phenotypic and ethnic diversity in studies. PMID:24124047

    2004-04-01

    The surgeon's objectives are normal nasolabial appearance and normal speech. The principles for synchronous repair of bilateral cleft lip have been established, and the techniques continue to evolve. Primary repair impairs maxillary growth, but little can be done at this time except to practice gentle craftsmanship and to minimize tension on the lower labial closure. The cutaneous lip should never be reopened for revision, and the number of secondary procedures involving the nasal cartilages should be kept to a minimum. Many adolescents with repaired bilateral cleft lip need maxillary advancement to improve projection of the nasal tip, to protrude the upper lip, and to attain normal sagittal skeletal harmony. With expected improvements in the technology of distraction osteogenesis, maxillary advancement may someday become as acceptable as orthodontic treatment.

  12. Clefting in pumpkin balloons

    NASA Astrophysics Data System (ADS)

    Baginski, F.; Schur, W.

    NASA's effort to develop a large payload, high altitude, long duration balloon, the Ultra Long Duration Balloon, focuses on a pumpkin shape super-pressure design. It has been observed that a pumpkin balloon may be unable to pressurize into the desired cyclically symmetric equilibrium configuration, settling into a distorted, undesired stable state instead. Hoop stress considerations in the pumpkin design leads to choosing the lowest possible bulge radius, while robust deployment is favored by a large bulge radius. Some qualitative understanding of design aspects on undesired equilibria in pumpkin balloons has been obtained via small-scale balloon testing. Poorly deploying balloons have clefts, but most gores away from the cleft deploy uniformly. In this paper, we present models for pumpkin balloons with clefts. Long term success of the pumpkin balloon for NASA requires a thorough understanding of the phenomenon of multiple stable equilibria and means for quantitative assessment of measures that prevent their occurrence. This paper attempts to determine numerical thresholds of design parameters that distinguish between properly deploying designs and improperly deploying designs by analytically investigating designs in the vicinity of criticality. Design elements which may trigger the onset undesired equilibria and remedial measures that ensure deployment are discussed.

    2015-01-01

    Cleft palate, including complete or incomplete cleft palates, soft palate clefts, and submucosal cleft palates, is the most frequent congenital craniofacial anomaly in humans. Multifactorial conditions, including genetic and environmental factors, induce the formation of cleft palates. The process of palatogenesis is temporospatially regulated by transcription factors, growth factors, extracellular matrix proteins, and membranous molecules; a single ablation of these molecules can result in a cleft palate in vivo. Studies on knockout mice were reviewed in order to identify genetic errors that lead to cleft palates. In this review, we systematically describe these mutant mice and discuss the molecular mechanisms of palatogenesis. PMID:26322171

    2009-09-01

    The frequency of associated cleft palate is known to be high in some fibroblast growth factor receptor 2 (FGFR2)-mediated craniosynostosis syndromes, such as Apert syndrome. However, there is little information on the frequency of palatal clefts in the FGFR2-mediated disorder, that is, Pfeiffer syndrome. The purpose of this study was to determine the frequency of palatal clefts in patients with Pfeiffer syndrome. The records of patients with Pfeiffer syndrome managed in our craniofacial unit were reviewed. Only patients with a confirmed diagnosis of Pfeiffer syndrome were included. Diagnostic criteria were as follows: characteristic mutations in FGFR1 or FGFR2 or, in the absence of genetic testing, clinical findings consistent with Pfeiffer syndrome as determined by a clinical geneticist or our most experienced surgeon (J.B.M.). Only 2 clefts were noted in 25 patients (8%), including 1 with a submucous cleft and 1 with an overt palatal cleft. Many patients (87%) were described as having a high-arched and narrow palate, and 1 had a low, broad palate. Nine patients were noted to have choanal atresia or stenosis. Clefting of the palate does occur in Pfeiffer syndrome but at a low frequency.

    To determine the clefting birth prevalence among Asian populations, specifically Chinese and Japanese, using raw counts from nonoverlapping published studies of Asian populations, and to investigate whether Asian clefting rates have been interpreted accurately as being up to twice the Caucasian rate. A literature review of articles giving raw counts of clefting in Asian populations, primarily Japanese and Chinese. Where possible, clefts were identified by the patients' ethnicity, country of origin, cleft type, syndromic status, and birth status. Prevalence rates of cleft lip with or without cleft palate per 1000 live births are reported. Syndromic plus nonsyndromic cleft lip with or without cleft palate: Chinese, 1.30; Japanese, 1.34; Other Asian, 1.47; and total, 1.33. Nonsyndromic cleft lip with or without cleft palate: Chinese, 1.20; Japanese, 1.18; Other Asian, 1.22; and total, 1.19. Overall, Chinese and Japanese live birth prevalence rates for nonsyndromic cleft lip with or without cleft palate, based on the published reports of birth prevalence, are significantly lower than the oft-quoted rate of 2 per 1000 for Asians. The apparent reason for the discrepancy is that many published prevalence rates included all pregnancies (live births plus pregnancy losses) and do not distinguish between syndromic and nonsyndromic clefts or between cleft palate alone and cleft lip with or without cleft palate. These results demonstrate that it is extremely important for current population-based studies of clefts to include careful delineation of population groups, syndromes, cleft type, and birth status.

    1990-12-01

    The storm time transport of ionospheric plasma from the cleft fountain to the plasma sheet and ring current is investigated by means of three-dimensional trajectory codes. Using observations to define the source location and flow rate. The authors trace test particles during a taillike to dipolelike reconfiguration of the geomagnetic field. Emphasis is placed on the behavior of heavy ions of low charge state (O{sup +}). As a result of their long periods of gyration, these ions are highly sensitive to rapid field variations and possible display transient nonadiabatic motions. It is demonstrated that O{sup +} which have originated in the high-latitude ionosphere but which find themselves in the vicinity of the equator at substorm onset can experience considerable erergization (from several keV up to several hundred keV) and pitch angle increase leading to trapping, as an effect of the induced electric field. These effects accompany a rapid earthward transport from midtail ({approximately}10-15 R{sub E}) to geosynchronous altitudes. The average particle energy and density involved suggest a substantial contribution of the cleft O{sup +} fountain to the ring current during substorms.

    Standards of cleft care abroad differ from those in the United States, particularly in less developed countries, where international adoption rates are high. Children adopted from these countries present to plastic surgeons in the United States at various ages and states of repair. The operative and perioperative needs of these children are poorly understood. This study attempts to characterize the preadoption history, the postadoption course, and surgical outcomes of children adopted with cleft deformities. The authors performed a retrospective review of all adopted cleft lip-cleft palate patients presenting to an academic craniofacial referral center and compared outcomes among adopted children who were repaired abroad, adopted children who underwent repair performed by the two senior authors (C.R.D. and S.B.B.), and children born in the United States who underwent repair performed by one of the senior authors (S.B.B.) : Between May of 1993 and August of 2010, 83 adopted children with cleft deformities were evaluated in the authors' craniofacial center. Average age at adoption was 30.5 months (range, 5.0 to 95.0 months). Comparing outcomes among adopted children repaired abroad, adopted children repaired by the senior authors, and children born in the United States who underwent repair in the United States, the authors found no statistically significant differences in lip revision rates, fistula rates, or velopharyngeal insufficiency. Adopted cleft patients constitute a complex and variable population with high rates of revision and delayed presentation. Internationally adopted children with orofacial clefts fared no better or worse after undergoing primary cleft repair abroad or in the United States.

    Background There is evidence for an effect of cigarette smoking on risk of oral clefts. There are also hypothetical pathways for a biological effect involving toxic chemicals in cigarette smoke. Methods We performed a combined case-control and family-triad study of babies born in Norway with oral clefts in the period 1996 to 2001, with 88% participation among cases (n=573) and 76% participation among controls (n=763). Mothers completed a questionnaire three months after birth of the baby. DNA was collected from parents and children, and assayed for genes related to detoxification of compounds of cigarette smoke (NAT1, NAT2, CYP1A1, GSTP1, GSTT1 and GSTM1). Results For isolated cleft lip (with or without cleft palate) there was a dose-response effect of smoking in the first trimester. The odds ratio rose from 1.6 (95% CI: 1.0 - 2.5) for passive smoking to 1.9 (95% CI: 0.9 - 4.0) for mothers who smoked more than 10 cigarettes per day. There was little evidence of an association with cleft palate. Genetic analyses used both case-control and family-triad data. In case-triads we found an association between a NAT2 haplotype and isolated cleft lip (RR of 1.6 in single dose and 2.5 in double dose), but with little evidence of interaction with smoking. Other genes did not show associations, and previously described interactions with smoking were not confirmed. Conclusion First-trimester smoking was clearly associated with risk of cleft lip. This effect was not modified by variants of genes related to detoxification of compounds of cigarette smoke. PMID:18449058

      This study examined malpractice claims related to cleft lip and cleft palate surgery to identify common allegations and injuries and reviewed financial outcomes.   The WestlawNext legal database was analyzed for all malpractice lawsuits and settlements related to the surgical repair of cleft lip and palate.   Inclusion criteria included patients undergoing surgical repair of a primary cleft lip or palate or revision for complications of previous surgery. Data evaluated included patient demographics, type of operation performed, plaintiff allegation, nature of injury, and litigation outcomes.   A total of 36 cases were identified, with 12 unique cases from 1981 to 2006 meeting the inclusion criteria. Six cases (50%) were decided by a jury and six by settlement. Five cases involved complications related to the specific surgery, and the other seven were associated with any surgery and perioperative care of children and adults. Cleft palate repair (50%) was the most frequently litigated surgery. Postoperative negligent supervision was the most common allegation (42%) and resulted in a payout in each case (mean = $3,126,032). Death (42%) and brain injury (25%) were the most frequent injuries reported. Financial awards were made in nine cases (after adjusting for inflation, mean = $2,470,552, range = $0 to $7,704,585). The awards were significantly larger for brain injury than other outcomes ($4,675,395 versus $1,368,131 after adjusting for inflation, P = .0101).   Malpractice litigation regarding cleft lip and palate surgery is uncommon. However, significant financial awards involving perioperative brain injury have been reported.

Knowledge has to be there about the different feeding positions like straddle, dancer hand position along with the use of specially designed bottles and nipples. Parent's should be trained about the correct positions of feeding, in extreme of the cases in which parents are not able to follow these instructions, feeding obturators can be given.

    2012-01-01

    Background Oral clefts are one of the most common birth defects with significant medical, psychosocial, and economic ramifications. Oral clefts have a complex etiology with genetic and environmental risk factors. There are suggestive results for decreased risks of cleft occurrence and recurrence with folic acid supplements taken at preconception and during pregnancy with a stronger evidence for higher than lower doses in preventing recurrence. Yet previous studies have suffered from considerable design limitations particularly non-randomization into treatment. There is also well-documented effectiveness for folic acid in preventing neural tube defect occurrence at 0.4 mg and recurrence with 4 mg. Given the substantial burden of clefting on the individual and the family and the supportive data for the effectiveness of folic acid supplementation as well as its low cost, a randomized clinical trial of the effectiveness of high versus low dose folic acid for prevention of cleft recurrence is warranted. Methods/design This study will assess the effect of 4 mg and 0.4 mg doses of folic acid, taken on a daily basis during preconception and up to 3 months of pregnancy by women who are at risk of having a child with nonsyndromic cleft lip with/without palate (NSCL/P), on the recurrence of NSCL/P. The total sample will include about 6,000 women (that either have NSCL/P or that have at least one child with NSCL/P) randomly assigned to the 4 mg and the 0.4 mg folic acid study groups. The study will also compare the recurrence rates of NSCL/P in the total sample of subjects, as well as the two study groups (4mg, 0.4 mg) to that of a historical control group. The study has been approved by IRBs (ethics committees) of all involved sites. Results will be disseminated through publications and presentations at scientific meetings. Discussion The costs related to oral clefts are high, including long term psychological and socio-economic effects. This study provides an opportunity for

    Four cases of facial cleft that fit the anatomic description of the rare Tessier no. 2 cleft, with two patients having the no. 12 cleft extending to the cranium as no. 2 clefts, are presented. In all patients, clinical expressions of the anomaly were different. Thus, diverse surgical procedures were used in all cases. These cases and review of the literature help to define the soft-tissue and bony course of these clefts, and also emphasize the role of three-dimensional computed tomography scan imaging to show the bony cleft route. The diagnosis and treatment plan of the no. 2 cleft as well as its cranial counterpart are discussed in this report.

    Children with isolated oral clefts have lower academic performance when compared with unaffected peers, yet few studies have examined specific attributes of clefts that may modify this risk. Oral clefts have nonrandom laterality, with left-sided clefts being more common than right-sided clefts, a pattern that may be genetically or environmentally influenced. The objective of this study was to evaluate the association between cleft laterality and academic achievement in a population-based sample of children with and without isolated oral clefts. The study included 292 children with isolated unilateral cleft lip with or without cleft palate identified by using the Iowa Registry for Congenital and Inherited Disorders matched with 908 unaffected classmates. This group provided 1953 child-grade observations for cases and 6829 for classmates. Academic achievement was evaluated by using high-quality standardized test data on multiple academic domains as well as use of special education. We found that children with right-sided clefts had similar achievement scores and usage of special education services compared with their unaffected classmates. Children with left-sided clefts had lower reading scores than children with right-sided clefts by nearly 7 percentiles (P < .05). They also had lower scores on all evaluated domains by 4 to 6 percentiles and greater use of special education services by 6 percentage points than their classmates. Children with left-sided clefts had poorer academic performance than their classmates or children with right-sided clefts, who showed similar academic achievement compared with their unaffected classmates.

    2010-02-01

    The geometry of a large axisymmetric balloon with positive differential pressure, such as a sphere, leads to very high film stresses. These stresses can be significantly reduced by using a tendon re-enforced lobed pumpkin-like shape. A number of schemes have been proposed to achieve a cyclically symmetric pumpkin shape, including the constant bulge angle (CBA) design, the constant bulge radius (CBR) design, CBA/CBR hybrids, and NASA’s recent constant stress (CS) design. Utilizing a hybrid CBA/CBR pumpkin design, Flight 555-NT in June 2006 formed an S-cleft and was unable to fully deploy. In order to better understand the S-cleft phenomenon, a series of inflation tests involving four 27-m diameter 200-gore pumpkin balloons were conducted in 2007. One of the test vehicles was a 1/3-scale mockup of the Flight 555-NT balloon. Using an inflation procedure intended to mimic ascent, the 1/3-scale mockup developed an S-cleft feature strikingly similar to the one observed in Flight 555-NT. Our analysis of the 1/3-scale mockup found it to be unstable. We compute asymmetric equilibrium configurations of this balloon, including shapes with an S-cleft feature.

    The cleft anomaly may be more ancient than the man himself. It is one of the most common developmental malformations reported in the literature. There are number of intriguing theories regarding its etiopathogenesis, each of which has some evidence in its favor. This review highlights all the genetic and environmental etiologic factors and focuses on its pathogenesis. PMID:22923895

    Bilateral cleft lip nose deformity is a multi-factorial and complex deformity which tends to aggravate with growth of the child, if not attended surgically. The goals of primary bilateral cleft lip nose surgery are, closure of the nasal floor and sill, lengthening of the columella, repositioning of the alar base, achieving nasal tip projection, repositioning of the lower lateral cartilages, and reorienting the nares from horizontal to oblique position. The multiplicity of procedures in the literature for correction of this deformity alludes to the fact that no single procedure is entirely effective. The timing for surgical intervention and its extent varies considerably. Early surgery on cartilage may adversely affect growth and development; at the same time, allowing the cartilage to grow in an abnormal position and contributing to aggravation of deformity. Some surgeons advocate correction of deformity at an early age. However, others like the cartilages to grow and mature before going in for surgery. With peer pressure also becoming an important consideration during the teens, the current trend is towards early intervention. There is no unanimity in the extent of nasal dissection to be done at the time of primary lip repair. While many perform limited nasal dissection for the fear of growth retardation, others opt for full cartilage correction at the time of primary surgery itself. The value of naso-alveolar moulding (NAM) too is not universally accepted and has now more opponents than proponents. Also most centres in the developing world have neither the personnel nor the facilities for the same. The secondary cleft nasal deformity is variable and is affected by the extent of the original abnormality, any prior surgeries performed and alteration due to nasal growth. This article reviews the currently popular methods for correction of nasal deformity associated with bilateral cleft lip, it's management both at the time of cleft lip repair and also secondarily

    Cleft palate affects almost every function of the face except vision. Today a child born with cleft palate with or without cleft lip should not be considered as unfortunate, because surgical repair of cleft palate has reached a highly satisfactory level. However for an average cleft surgeon palatoplasty remains an enigma. The surgery differs from centre to centre and surgeon to surgeon. However there is general agreement that palatoplasty (soft palate at least) should be performed between 6-12 months of age. Basically there are three groups of palatoplasty techniques. One is for hard palate repair, second for soft palate repair and the third based on the surgical schedule. Hard palate repair techniques are Veau-Wardill-Kilner V-Y, von Langenbeck, two-flap, Aleveolar extension palatoplasty, vomer flap, raw area free palatoplasty etc. The soft palate techniques are intravelar veloplasty, double opposing Z-plasty, radical muscle dissection, primary pharyngeal flap etc. And the protocol based techniques are Schweckendiek's, Malek's, whole in one, modified schedule with palatoplasty before lip repair etc. One should also know the effect of each technique on maxillofacial growth and speech. The ideal technique of palatoplasty is the one which gives perfect speech without affecting the maxillofacial growth and hearing. The techniques are still evolving because we are yet to design an ideal one. It is always good to know all the techniques and variations so that one can choose whichever gives the best result in one's hands. A large number of techniques are available in literature, and also every surgeon incorporates his own modification to make it a variation. However there are some basic techniques, which are described in details which are used in various centres. Some of the important variations are also described. PMID:19884664

    Birth abnormalities like cleft lip and cleft palate account for about 1.4 per 1000 live births in India. These are seen to be associated with a high incidence of eosinophilia which delays the surgical management of these patients. The aim of this paper is to study the hematological parameters in patients of cleft lip and cleft palate. A total of 223 cases of cleft lip and cleft palate were taken up for the study. Hematological parameters including hemoglobin, total leukocyte count, differential leukocyte count, absolute eosinophil count, and red cell indices were studied. Anemia was found in 182/223 (81.63%) cases which was most commonly of microcytic hypochromic type. Eosinophilia was seen in 46/223 (20.60%) cases. Many cleft lip and cleft palate patients show high eosinophil counts. Absolute eosinophil count was found to be a better parameter for assessment of eosinophils.

    There are many countries in the world where patients with cleft lip and palate cannot get access to specialized cleft care units. Cleft missions play an important role in providing surgical care to the areas of the world with limited resources. This article presents a model of cleft missions that can be adopted in many countries where expertise is available but resources are limited. Through proper utilization of local human resource, this type of mission can be a cost-effective and robust way of treating patients with cleft in countries with approximately 52% of the world's population. We present a case series of patients of one of our cleft missions carried out in Khairpur, Pakistan, in March 2014 over a period of 7 days. Specific details concerning the organization of mission, gathering of patients, preparation for surgery, and carrying out surgical procedures in a safe and swift manner are presented. A total of 312 patients were operated on in 7 days. There were 145 patients with cleft lip and 167 patients with cleft palate. There were 187 male and 125 female patients with mean age of 7 years. Contemporary operative techniques were utilized to repair different types of cleft lip and palate. Of 167 patients, only 16 developed fistula. A locoregional cleft team can be more effective to care for the patients with cleft in countries where surgical and other expertise can be utilized by proper organization of cleft missions on a national level.

    Orofacial clefts (OFC) are the most common malformations of the head and neck. In Africa, OFC is under-ascertained with little or no surveillance system in most parts for clefts and other birth defects. A Nigerian craniofacial anomalies study “NigeriaCRAN” was established in 2006 to support cleft research specifically for epidemiological studies, treatment outcomes and; studies into etiology and prevention. We pooled data from seven of the largest Smile Train treatment centers in the six geopolitical zones in Nigeria. Data from September 2006 to June 2011 were analyzed and clefts compared between sides and gender using the Fisher’s exact test. A total of 2197 cases were identified during the study period with an estimated prevalence rate of 0.5/1000. Of the total number of OFC, 53.3% are males and 47%.7 are females. There was a significant difference (p=0.0001) between unilateral left clefts and unilateral right clefts and; significant difference (p=0.0001) between bilateral clefts and either clefts on the left or right side. A significant gender difference (p=0.03) with more females than males was also observed for CP. A total of 103 (4.7 %) associated anomalies were identified, nine syndromic cleft cases and 10.4 % of the total number of clefts individuals have an affected relative. The significant difference between unilateral clefts and gender differences in the proportion of cleft palate only are consistent with the literature. The present study emphasizes the need for birth defects registries in developing countries in order to estimate the exact prevalence of birth defects including OFC. PMID:23557093

    It is generally accepted that subducted oceanic crust and sediments contribute to the composition of arc magmas. Systematic variations of input parameters (including age, subduction angle, and chemical composition of the subducting material) make the Central American Volcanic Arc (CAVA), which extends from Guatemala in the northwest through El Salvador, Honduras, Nicaragua, Costa Rica and Panama to the southeast, a prime study object. We present a comprehensive (major and trace element and Sr-Nd-Pb-Hf isotope data) and consistent (all data generated in the same labs using the same methods and data reduction procedures) compilation of published and unpublished Holocene mafic volcanic rocks sampled along the entire arc. New data include Sr and, for the first time, Hf isotope data from the entire CAVA as well as major and trace element data for 43 samples from southern Nicaragua and central Costa Rica from which only isotopic compositions were previously published. The combined elemental and isotopic data confirm the influence of distinct subduction components on the composition of CAVA magmas. Along-arc geochemical variations (especially delta 208Pb/204Pb) of volcanic front magmas in Costa Rica and Panama have been explained by the different compositions of seamounts/ridges of the isotopically zoned Galápagos hotspot track that covers the subducting Cocos Plate in this sector of the arc (Hoernle et al. 2008, Nature 451). Our new data confirm this relationship with arc lavas from Costa Rica having higher 87Sr/86Sr ratios than those from western Panama reflecting a similar spatial-compositional distinction in the subducting hotspot track beneath them. In contrast, 176Hf/177Hf shows no comparable variations in this sector of the arc, indicating that the Hf is primarily derived from the mantle wedge rather than the subducting slab. Although small degree hydrous melts are believed to fertilize the mantle wedge beneath Costa Rica, residual zircon may hold back the Hf.

    It has been suggested that among American Indians, as in some genetically-related Asiatic ethnic groups, incidence of cleft lip and/or cleft palate is higher than among people of Caucasian extraction. Such hypothesis, plus growing demand for services observed at a center for the surgery of cleft lip and cleft palate in Campeche state, led the authors to undertake research among the Maya residents of that region. However, neither careful review of case histories nor field research performed in several Indian communities could confirm the hypothesis of a higher incidence among this ethnic community.

    Cleft lip and palate is the most frequent congenital craniofacial deformity. In this article, the authors describe their experience with cleft lip and palate repair. Data regarding patients presenting with primary diagnosis of cleft lip and/or palate, between 2009 and 2015, were reviewed. Details including demographics, type of cleft, presence of known risk factors, surgical details, and follow-up visits were collected. Documented complications were reported. Caregivers' satisfaction was assessed with a survey. The survey used to assess satisfaction with cleft-related features was based on the cleft evaluation profile (CEP). In addition, 4 assessors used visual analog scale (VAS) to assess the aesthetic satisfaction. Seven hundred fifty-two patients with primary diagnosis of cleft lip and/or palate underwent surgical correction at "S. Chiara" Hospital, 432 (57.45%) male and 320 (42.55%) female. The most common cleft types in our study were incomplete cleft palate (152 patients) and left unilateral complete cleft lip and palate (152 patients). Associated syndromes were found in 46 patients (6.12%). Cleft lip was repaired using a modified Tennison-Randall technique when the defect was unilateral, whereas a modified Mulliken technique was used for bilateral cleft lip. Cleft palate was repaired using the Bardach technique or Von Langenbeck technique at 5 to 6 months of age. Cleft lip and palate was repaired in several surgical steps. In total, complications were reported in 81 of 752 patients (14.16%). Average fathers' satisfaction score assessed using CEP was 4.5 (lip), 4.8 (nose), 4.7 (teeth), 4.8 (bite), 4.2 (breathing), 4.6 (profile). Average mothers' satisfaction score assessed using CEP was 4.3 (lip), 4.6 (nose), 4.4 (teeth), 4.5 (bite), 4.1 (breathing), 4.4 (profile). Average level of aesthetic satisfaction, assessed using VAS, was 8.7 (fathers), 8.1 (mothers), 7.9 (lay person), and 8.0 (senior cleft surgeon). The multidisciplinary management of children with

    Surgical cleft repair aims to restore function of the oro-nasal sphincter and oro-nasal soft tissues and re-establish the complex relationship between perioral and perinasal muscle rings without compromising subsequent mid-facial growth and development. Here we review the surgical anatomy of this region, optimal timing for surgical repair and current thinking on the use of surgical adjuncts. In addition, an overview of current surgical techniques available for the repair of cleft lip, cleft palate and velopharyngeal insufficiency is presented. Finally, we briefly discuss nasal revision surgery and the use of osteotomy, including distraction osteogenesis in the cleft patient.

    During the magnetic storm of February 8-9, 1986, the region of strong ion convection in the vicinity of the dayside cusp expanded equatorward into the field of view of the Millstone Hill radar at lower mid-latitudes. High-speed (>1.5 km/s) poleward ion flows were found at latitudes as low as 60 deg invariant latitude, at least 10 deg lower than the typical cleft/cusp position for moderately disturbed (Kp>4) magnetospheric conditions. The ion velocity pattern responded promptly to changes in the interplanetary magnetic field By direction. The large-scale two-dimensional convection pattern across the dayside was well resolved using radar azimuth scan data at Millstone Hill, thus enabling us to place the fine-scale radar/satellite observations of the storm time cusp and cleft in the context of the large-scale pattern. We present a detailed comparison of radar and DMSP F7 satellite observations in the prenoon sector during a period of Kp > 7, to examine the low-altitude signatures of various plasma regions in the vicinity of the cusp. The combination of particle precipitation, magnetic field perturbation, radar measurements of ion heating, and convection consistently suggests the unusual low-latitude position of cusp at 65 invariant latitude.

    Background Small studies have indicated that twinning increases the risk of oral cleft. Methods We used data from a Danish national population-based cohort study to investigate whether twinning was associated with isolated oral cleft, and to estimate the twin probandwise concordance rate and heritability. Twins (207 affected/130,710) and singletons (7766 affected/4,798,526) born from 1936 through 2004 in Denmark were ascertained by linkage among the Danish Facial Cleft Database, the Danish Twin Registry and the Civil Registration System. We computed oral cleft prevalence and prevalence proportion ratio for twins versus singletons, stratified for three sub-phenotypes. Probandwise concordance rates and heritability for twins were estimated for two phenotypes—cleft lip with or without cleft palate (CL/P) and cleft palate (CP). Results The prevalence of oral cleft was 15.8 per 10,000 twins and 16.6 per 10,000 singletons (prevalence proportion ratio = 0.95; 95% confidence interval = 0.83 – 1.1). This prevalence was similar for monozygotic and dizygotic twins. The probandwise concordance rate was higher for CL/P for monozygotic twins than for dizygotic twins (50 % vs. 8%, respectively). A similar contrast was present for CP. Recurrence risk for both types of clefts was greater in dizygotic twins than in non-twin siblings. Heritability estimates were above 90% for both CL/P and CP. Conclusion No excess risk of oral cleft could be demonstrated for twins compared with singletons. The concordance rates and heritability estimates for both types of clefts show a strong genetic component. PMID:21423016

    Numerous bone and soft tissue grafting techniques are followed to repair cleft of lip and palate (CLP) defects. In addition to the gold standard surgical interventions involving the use of autogenous grafts, various allogenic and xenogenic graft materials are available for bone regeneration. In an attempt to discover minimally invasive and cost effective treatments for cleft repair, an exceptional growth in synthetic biomedical graft materials have occurred. This study gives an overview of the use of dental materials to repair cleft of lip and palate (CLP). The eligibility criteria for this review were case studies, clinical trials and retrospective studies on the use of various types of dental materials in surgical repair of cleft palate defects. Any data available on the surgical interventions to repair alveolar or palatal cleft, with natural or synthetic graft materials was included in this review. Those datasets with long term clinical follow-up results were referred to as particularly relevant. The results provide encouraging evidence in favor of dental and other related biomedical materials to fill the gaps in clefts of lip and palate. The review presents the various bones and soft tissue replacement strategies currently used, tested or explored for the repair of cleft defects. There was little available data on the use of synthetic materials in cleft repair which was a limitation of this study. In conclusion although clinical trials on the use of synthetic materials are currently underway the uses of autologous implants are the preferred treatment methods to date.

    A 48-year-old man presented with hyphema, iridocyclitis, iridophacodonesis, and maculopathy after a contusive trauma. Ultrasound biomicroscopy identified a 90-degree cyclodialysis cleft with severe damage of the zonular fibers. Echographic B-scan examination revealed intravitreal hemorrhage and a 360-degree choroidal detachment. One month later, phacoemulsification was performed and a single-piece poly(methyl methacrylate) intraocular lens was inserted into the ciliary sulcus, with the haptic rotated toward the cyclodialysis cleft area. Postoperatively, the visual acuity improved and the intraocular pressure returned to normal. Ultrasound biomicroscopy showed closure of the cleft by reattachment of the ciliary body to the scleral spur. Optical coherence tomography revealed complete resolution of the macular and choroidal folds. Ultrasound biomicroscopy is a useful method for appropriate management of traumatic cyclodialysis cleft. In cases of small cyclodialysis clefts, with the surgical method we describe, the lens haptics apply directional force toward the sclera, fostering adherence of the ciliary body fibers.

    Saturn's largest moon Titan hosts an atmosphere with complex organic chemistry initiated in the ionosphere. The nightside chemistry may be influenced by the ion transport from the dayside ionosphere. In turn, ion transport (ion drifts) may be affected by the neutral winds, which cannot be measured directly by Cassini. In this study we derive the ion drifts along the spacecraft trajectories based on analysis of in-situ measurements of electron and ion fluxes, positive and negative ion masses and the magnetic field. Data from Titan flybys TA to T100 was included (Oct 2005 - Apr 2014), of which 55 flybys were below 1400 km and 48 below 1200 km altitude. From the electron and ion flux measurements three regions were observed: 1) above 1600 km, ions are ExB-drifting (frozen into the fields), 2) 1100-1600 km altitudes, dynamo-region, ions drift in opposite directions (perpendicular to B) and 3) 880-1100 km altitude (upper limit depends on convection electric field strength), ions are following neutrals and ion drifts translate to neutral winds of 0.5-2.5 km/s with weaker winds on the dayside of Titan's ionosphere.

    BACKGROUND: Socialized health systems face fiscal constraints due to a limited supply of resources and few reliable ways to control patient demand. Some form of prioritization must occur as to what services to offer and which programs to fund. A data-driven approach to decision making that incorporates outcomes, including safety and quality, in the setting of fiscal prudence is required. A value model championed by Michael Porter encompasses these parameters, in which value is defined as outcomes divided by cost. OBJECTIVES: To assess ambulatory cleft lip surgery from a quality and safety perspective, and to assess the costs associated with ambulatory cleft lip surgery in North America. Conclusions will be drawn as to how the overall value of cleft lip surgery may be enhanced. METHODS: A value analysis of published articles related to ambulatory cleft lip repair over the past 30 years was performed to determine what percentage of patients would be candidates for ambulatory cleft lip repair from a quality and safety perspective. An economic model was constructed based on costs associated with the inpatient stay related to cleft lip repair. RESULTS: On analysis of the published reports in the literature, a minority (28%) of patients are currently discharged in an ambulatory fashion following cleft lip repair. Further analysis suggests that 88.9% of patients would be safe candidates for same-day discharge. From an economic perspective, the mean cost per patient for the overnight admission component of ambulatory cleft surgery to the health care system in the United States was USD$2,390 and $1,800 in Canada. CONCLUSIONS: The present analysis reviewed germane publications over a 30-year period, ultimately suggesting that ambulatory cleft lip surgery results in preservation of quality and safety metrics for most patients. The financial model illustrates a potential cost saving through the adoption of such a practice change. For appropriately selected patients, ambulatory

    The International Task Force on Volunteer Cleft Missions was set up to provide a report to be presented at the Eighth International Congress of Cleft Palate and Associated Craniofacial Anomalies on September 12, 1997, in Singapore. The aim of the report was to provide data from a wide range of different international teams performing volunteer cleft missions and, thereafter, based on the collected data, to identify common goals and aims of such missions. Thirteen different groups actively participating in volunteer cleft missions worldwide were selected from the International Confederation of Plastic and Reconstructive Surgery's list of teams actively participating in volunteer cleft missions. Because of the time frame within which the committee had to work, three groups that did not respond by the stipulated deadline were omitted from the committee. The represented members and their respective institutions have undertaken more than 50 volunteer cleft missions to underdeveloped nations worldwide within the last 3 years. They have visited over 20 different countries, treating more than 3,500 patients worldwide. Based on the data collected and by consensus, the committee outlined recommendations for future volunteer cleft missions based on 1) mission objectives, 2) organization, 3) personal health and liability, 4) funding, 5) trainees in volunteer cleft missions, and 6) public relations. The task force believed that all volunteer cleft missions should have well-defined objectives, preferably with long-term plans. The task force also decided that it was impossible to achieve a successful mission without good organization and close coordination. All efforts should be made, and care taken, to ensure that there is minimal morbidity and no mortality. Finally, as ambassadors of goodwill and humanitarian aid, the participants must make every effort to understand and respect local customs and protocol. The main aims are to provide top-quality surgical service, train local

    To evaluate whether a nasal gel, administrated using a radial-hole inhaler, reaches the olfactory cleft and if a different administration method influences distribution. Sixteen healthy volunteers underwent a nasal endoscopy at 1 and 7minutes after the administration of a intranasal gel, with a different method in each fossa. No dye deposition was identified at the olfactory cleft, middle turbinate or middle meatus. In all cases the gel was identified at the nasal vestibule. On the right side, the second most frequent dye identification area was the inferior turbinate, with a rate of 87% at the first minute and 75% at 7 minutes. It was followed by the septum (75 and 62%) and the inferior meatus (6.2 and 12.5%). On the left side, the second most frequent stained area was the septum (18.7 and 13.5%), followed by the inferior meatus (6.5 and 65%). No inferior turbinate staining was found in the left side. There was a significant difference in the deposition rate at the septum (P<.01) and inferior turbinate (P<.001), when both administration methods were compared. No nasal gel, administrated using a radial-hole inhaler, was found at the olfactory cleft, middle turbinate or middle meatus. Gel distribution was located at the anterior and inferior portion of the nose, independent of the administration method used. Significantly different gel distribution rates were found at the septum and inferior turbinate when the 2 administration methods were compared. Copyright © 2012 Elsevier España, S.L.

    To study the relationship of cleft severity and maxillary growth in patients with unilateral cleft lip and palate. A systematic literature review. A literature survey from the PubMed database from January 1966 to December 2008 used the Medical Subject Headings terms facial growth, unilateral cleft lip palate, cephalometry, and cleft severity or cleft width. The Cleft Palate-Craniofacial Journal from 1964 to November 2008 was hand searched. Studies published as full-length articles reporting quantitative data on the relationship of cleft severity and written in English were selected. Two reviewers selected and extracted the data independently and also assessed the quality of the studies. Four studies met the selection criteria and were included in the review. All were retrospective and longitudinal. Quality analysis revealed medium to low level of the included studies. Heterogeneity of the studies prevented major conclusions about the relationship of a severe cleft and unfavorable maxillary forward growth. The review has highlighted the importance of further research. Further well-designed controlled studies and long-term studies are needed, and researchers have to consider combined assessment of cleft size and palate size. Further studies should also focus on the cleft severity at birth and at the time of palate repair.

    To investigate current trends in primary treatment for children with cleft lip and/or cleft palate in Japan. Nationwide, retrospective study under the direction of the Academic Survey Committee of the Japanese Cleft Palate Association based on analysis of data obtained via a booklet-style questionnaire completed by institutions providing primary treatment for cleft lip and/or palate patients. PARTICIPANTS, PATIENTS: Patients were 4349 children undergoing primary repair for cleft lip and/or palate at 107 participating institutions between 1996 and 2000. Cleft type, laterality; use of infant palatal plate; and timing and technique of primary repair for cleft lip and/or palate were evaluated by cleft surgeons at 107 participating institutions. Of a total of 2874 patients with cleft lip and palate or cleft palate only, infant palatal plates were used with 1087 (37.8%) and were not used with 1787 (62.2%). Primary unilateral lip repair was performed at the age of 2 to 6 months in more than 90% of patients. Bilateral cleft lip was treated by one-stage repair in 285 patients (44.5%) and by two-stage repair in 258 (40.2%). Primary one-stage palatal repair was performed in 2212 (76.9%) and two-stage palatal repair in 262 (9.1%) cleft palate patients. Information on treatment of the remaining 400 (14%) patients was unavailable. This investigation clarified current trends in primary treatment for cleft lip and/or palate in Japan. The results suggest the need for an increase in regional core hospitals and greater variation in treatment options.

    Individuals with nonsyndromic cleft lip with or without cleft palate (NSCL±P) present high frequency of dental anomalies, which may represent complicating factors for dental treatment. The aim of this study was to investigate the prevalence of dental anomalies inside cleft area in a group of Brazilians with NSCL±P. Retrospective analysis of 178 panoramic radiographs of patients aged from 12 to 45 years old and without history of tooth extraction or orthodontic treatment was performed. Association between cleft type and the prevalence of dental anomalies was assessed by chi-square test with a significance level set at p≤ 0.05. Dental anomalies were found in 88.2% (n=157) of the patients. Tooth agenesis (47.1%), giroversion (20%) and microdontia (15.5%) were the most common anomalies. Individuals with unilateral complete cleft lip and palate (CLP, p<0.0001), bilateral complete CLP (p=0.0002) and bilateral incomplete CLP (p< 0.0001) were more affected by tooth agenesis than individuals with other cleft types. The maxillary lateral incisors were the most affected teeth (p<0.0001). The present study revealed a high frequency of dental anomalies inside cleft region in NSCL±P patients, and further demonstrated that patients with unilateral complete CLP and bilateral incomplete CLP were frequently more affected by dental anomalies. Moreover, our results demonstrate that dental anomalies should be considered during dental treatment planning of individuals affected by NSCL±P.

    Unusual facial cleft in Fryns syndrome: defect of stomodeum?: We report on a fetus with Fryns syndrome. The facial cleft was unusual. There was bilateral cleft lip with cleft palate. The intermaxillary segment was connected through the base of a mound in the midline to the lower lip. We believe this is an atypical facial cleft in Fryns syndrome and likely represents a defective stomodeum.

    Objective : Orofacial clefts such as cleft lip, cleft palate, and cleft lip and palate are the most frequent congenital anomalies of the head and neck. The purpose of this study was to determine the current demographics for orofacial clefts in Canada. Methods : A request for data from all Canadian provinces (excluding Quebec due to incompatibilities with provincial coding systems) for the fiscal years 2002-2003 to 2007-2008 was submitted to the Canadian Institute for Health Information. Variables evaluated included gender, cleft type, gestational age, birth weight, income quintile, and institution health region. Results : Over the period studied, the prevalence of orofacial clefts ranged from 11.0 to 15.3 per 10,000 live births (1 in 654 to 1 in 909 live births). The distribution of cleft types for live births with orofacial clefts was 17% for cleft lip, 41% for cleft palate, and 42% for cleft lip and palate, of which cleft lip and cleft lip and palate were male dominant (62% and 66% male, respectively) and cleft palate was female dominant (56% female). Saskatchewan and Manitoba had significantly higher cleft birthrates (P < .05) compared with the other provinces. Birth weight and gestational age (but not income quintile) were significantly (P < .0001) lower for newborns with orofacial clefting compared with those with no cleft. Conclusions : Canada has one of the highest orofacial cleft birthrates in the world (prevalence of 12.7 per 10,000 live births, approximately 1 in 790 live births). This study presents an updated demographic of orofacial clefts in Canadian newborns and may be useful in predicting the burden of anticipated health care.

    The Pittsburgh Oral-Facial Cleft study was begun in 1993 with the primary goal of identifying genes involved in nonsyndromic orofacial clefts in a variety of populations worldwide. Based on the results from a number of pilot studies and preliminary genetic analyses, a new research focus was added to the Pittsburgh Oral-Facial Cleft study in 1999: to elucidate the role that associated phenotypic features play in the familial transmission patterns of orofacial clefts in order to expand the definition of the nonsyndromic cleft phenotype. The purpose of this paper is to provide a comprehensive review of phenotypic features associated with nonsyndromic orofacial clefts. These features include fluctuating and directional asymmetry, non-right-handedness, dermatoglyphic patterns, craniofacial morphology, orbicularis oris muscle defects, dental anomalies, structural brain and vertebral anomalies, minor physical anomalies, and velopharyngeal incompetence.

    To describe two patients with mesencephalic midline clefts and associated eye movement disorders. Case reports. The first patient developed bilateral internuclear ophthalmoplegia with exotropia, reduced convergence, right ptosis, right fourth-nerve palsy, and right elevator palsy several years after meningitis with hydrocephalus. The second patient had bilateral internuclear ophthalmoplegia with exotropia, reduced convergence, bilateral ptosis, limited upward gaze, and right hypertropia since childhood. In both patients, magnetic resonance imaging showed a midline cleft extending from the cerebral aqueduct into the midbrain. It is likely that the clefts affected the oculomotor nuclei and medial longitudinal fasciculi, accounting for the eye movement disorders.

    Initial cleft severity in patients with complete unilateral cleft lip and palate (UCLP) varies. This is reflected in the sizes of the cleft and the palate. The purpose of this retrospective study was to establish whether there is a relationship between cleft severity at birth and growth of the maxilla. Maxillary dental casts of 29 infants with nonsyndromic complete UCLP were used to measure the sizes of the cleft and the palate. The later growth of the maxilla was determined by using cephalometric radiographs taken at age 9. Statistical analyses were performed with multiple linear regression. The results showed a relationship between cleft area and maxillary protrusion (SNA, P <0.05). Also, there was a relationship between palate area and maxillary width (P <0.05). These data suggest that in patients with complete UCLP there is a significant relationship between initial cleft severity and maxillary growth. Patients with a small cleft area have a more protruded maxilla than do those with a large cleft area. Patients with a large palate area have a wider maxilla than those with a small palate area.

    To estimate the number of new cases of cleft lip and cleft palate in the department (state) of Alta Verapaz, Guatemala, in 2012. Cross-sectional survey of midwives from communities identified through a two-stage cluster-sampling process. Midwives were asked how many babies they had delivered in the past year and how many of those newborns had various types of birth defects, as illustrated in pictures. Indigenous Mayan communities in rural north-central Guatemala. Midwives (n = 129) who had delivered babies in the previous year. Reports of babies born with cleft lip and cleft palate. A 1-year prevalence rate of 18.9 per 10,000 for cleft lip and 4.7 per 10,000 for cleft palate was estimated for Alta Verapaz. None of the cases of cleft lip also had cleft palate. The indigenous communities in north-central Guatemala might have a relatively high cleft lip prevalence rate compared with the global average.

    Preterm infants (PIs) often require respiratory support due to surfactant deficiency. Early weaning from mechanical ventilation to noninvasive respiratory support decreases ventilation-associated irreversible lung damage. This wean is particularly challenging in PIs with cleft lip and cleft palate due to anatomical difficulties encountered in maintaining an adequate seal for positive pressure ventilation. PI with a cleft lip and palate often fail noninvasive respiratory support and require continued intubation and mechanical ventilation. We are presenting the first case report of a PI with cleft lip and palate who was managed by biphasic nasal continuous positive airway pressure. PMID:26495158

    Maxillary growth in patients with cleft lip and palate is highly variable. The authors' aim was to investigate associations between preoperative cleft lip measurements and maxillary growth determined cephalometrically in patients with complete unilateral cleft lip and palate (cUCLP). Retrospective cross-sectional study. Children with cUCLP. Preoperative cleft lip measurements were made at the time of primary cheiloplasty and available for each patient. Maxillary growth was evaluated on lateral cephalometric radiographs taken prior to any orthodontic treatment and alveolar bone grafting (8.5 ± 0.7 years). The presence of associations between preoperative cleft lip measurements and cephalometric measures of maxillary growth was determined using regression analyses. In the 58 patients included in the study, the cleft lateral lip element was deficient in height in 90% and in transverse width in 81% of patients. There was an inverse correlation between cleft lateral lip height and transverse width with a β coefficient of -0.382 (P = .003). Patients with a more deficient cleft lateral lip height displayed a shorter maxillary length (β coefficient = 0.336; P = .010), a less protruded maxilla (β coefficient = .334; P = .008), and a shorter anterior maxillary height (β coefficient = 0.306; P = .020) than those with a less deficient cleft lateral lip height. Patients with cUCLP present with varying degrees of lateral lip hypoplasia. Preoperative measures of lateral lip deficiency are related to later observed deficiencies of maxillary length, protrusion, and height.

    A normal feature of the facial anatomy of many species of bat is the presence of bony discontinuities or clefts, which bear a remarkable similarity to orofacial clefts that occur in humans as a congenital pathology. These clefts occur in two forms: a midline cleft between the two premaxillae (analogous to the rare midline craniofacial clefts in humans) and bilateral paramedian clefts between the premaxilla and the maxillae (analogous to the typical cleft lip and palate in humans). Here, we describe the distribution of orofacial clefting across major bat clades, exploring the relationship of the different patterns of clefting to feeding mode, development of the vomeronasal organ, development of the nasolacrimal duct and mode of emission of the echolocation call in different bat groups. We also present the results of detailed radiographic and soft tissue dissections of representative examples of the two types of cleft. The midline cleft has arisen independently multiple times in bat phylogeny, whereas the paramedian cleft has arisen once and is a synapomorphy uniting the Rhinolophidae and Hipposideridae. In all cases examined, the bony cleft is filled in by a robust fibrous membrane, continuous with the periosteum of the margins of the cleft. In the paramedian clefts, this membrane splits to enclose the premaxilla but forms a loose fold laterally between the premaxilla and maxilla, allowing the premaxilla and nose-leaf to pivot dorsoventrally in the sagittal plane under the action of facial muscles attached to the nasal cartilages. It is possible that this is a specific adaptation for echolocation and/or aerial insectivory. Given the shared embryological location of orofacial clefts in bats and humans, it is likely that aspects of the developmental control networks that produce cleft lip and palate in humans may also be implicated in the formation of these clefts as a normal feature in some bats.

    Our aim was to describe the postoperative management and wound care protocol after primary cleft lip closure, as it has been used in the Bruges Cleft and Craniofacial Center at the supraregional teaching hospital AZ St. Jan, Bruges, between June 1, 1991, and July 1, 2009. The postoperative management and wound care included the use of a Logan bow, long-acting local anesthetic, elbow restraints, antibiotic therapy, crust removal with normal saline solution, and a special local wound ointment that was prepared at our center. During the last 19 years, 199 unilateral and 103 bilateral cleft lip patients have been repaired. 2.6% showed postoperative infection and/or dehiscence. One percent required readmission for reoperation. In 1.6%, inflammatory reaction was treated with oral antibiotics. The specific wound dressing ointment, as it is prepared in our department, could meet the requirements of primary wound management after cleft lip closure.

    Orofacial clefts comprise a range of congenital deformities and are the most common head and neck congenital malformation. Clefting has significant psychological and socio- economic effects on patient quality of life and require a multidisciplinary team approach for management. The complex interplay between genetic and environmental factors play a significant role in the incidence and cause of clefting. In this review, the embryology, classification, epidemiology, and etiology of cleft lip are discussed. The primary goals of surgical repair are to restore normal function, speech development, and facial esthetics. Different techniques are employed based on surgeon expertise and the unique patient presentations. Pre-surgical orthopedics are frequently employed prior to definitive repair to improve outcomes. Long term follow up and quality of life studies are discussed. PMID:24400297

    Although children with oral clefts have a higher risk for dental anomalies when compared with the general population, prior studies have shown conflicting results regarding their dental decay risk. Also, few studies have assessed dental decay risk in unaffected relatives of children with clefts. Thus, the question of increased risk of dental decay in individuals with oral clefts or their unaffected relatives is still open for empirical investigation. This study characterizes dental decay in the largest international cohort to date of children with nonsyndromic clefts and their relatives, as compared with controls, and it addresses whether families with oral clefts have a significantly increased risk for dental decay versus the general population. A total of 3,326 subjects were included: 639 case probands, 1,549 unaffected relatives, and 1,138 controls. Decay was identified from in-person dental examinations or intraoral photographs. Case-control differences were tested with regression analysis. No significant differences were shown in percentage decayed and filled teeth and decayed teeth in the primary dentition (dft, dt) and permanent dentition (DFT, DT) in cases versus controls. In the cleft region, no significant differences were seen in primary or permanent decay (dt, DT) when compared with controls. No difference was found with regard to cleft type and percentage dft, dt, DFT, and DT in case probands. Nonsignificant differences were found in unaffected siblings and parents versus controls (primary and permanent dentitions). Collectively, these findings indicate that individuals with nonsyndromic oral clefts and their families do not have a higher dental decay risk as compared with the general population. These results suggest that either genetic or environmental factors underlying a higher susceptibility for dental anomalies do not increase caries risk or that the seemingly higher risk for dental decay associated with increased dental anomalies in case

    To examine the prevalence of different types of dental anomalies in children with nonsyndromic cleft lip, unilateral cleft lip-palate, and bilateral cleft lip-palate. A sample of 90 patients (aged 4-20 years) affected by isolated cleft lip, unilateral and bilateral cleft lip and palate was examined. Cleft patients were classified into one of three groups according to cleft type: (1) Unilateral Cleft Lip-Palate, (2) Bilateral Cleft Lip-Palate, and (3) Cleft Lip. Intraoral exams, panoramic radiographs and dental casts, were used to analyse the prevalence of the various dental anomalies included in this study. There were no statistically significant differences between patients with cleft lip, unilateral cleft lip and palate and bilateral cleft lip and palate. The congenital absence of the cleft-side lateral incisor was observed in 40% of the sample, and a total of 30% patients showed supernumerary teeth at the incisors region. Second premolar agenesis was found in 4.4% of patients, whereas in 18.9% of the sample there was an ectopic dental eruption. Lateral or central incisors rotation was noted in 31.1% of the sample, while shape anomaly, lateral incisor microdontia, and enamel hypoplasia were detected respectively in 25.6%, 5.6% and 18.9% of cleft patients. High prevalence of different dental anomalies in children with cleft lip and unilateral and bilateral cleft lip and palate has been confirmed. This study, in particular, shows the presence of ectopic and rotated teeth in the cleft area.

    We aimed to characterize the fibroblast phenotype of patients by analyzing gene and protein expression of cleft lip and/or cleft palate fibroblasts in relation to collagen turnover and extracellular matrix remodeling. Human palatal fibroblasts were obtained from three healthy subjects without cleft lip and/or cleft palate and from three subjects with nonsyndromic cleft lip and/or cleft palate. Collagen turnover-related gene and protein expression were analyzed by real-time polymerase chain reaction, Western and dot blots, and sodium dodecyl sulfate zymography. Cleft lip and/or cleft palate fibroblasts, compared with controls, displayed a down-regulation of collagens type I and III messenger RNA (p < .0001 and p < .001, respectively) but an opposite tendency to increase protein levels. Cleft lip and/or cleft palate cells had higher lysyl hydroxylase-2b messenger RNA levels expressed in relation to collagen type I messenger RNA, down-regulated matrix metalloproteinase-1, tissue inhibitor of matrix metalloproteinase-1, and Secreted Protein Acidic and Rich in Cysteine messenger RNA (p < .0001 and p < .01, respectively). Pro-matrix metalloproteinase-1 tended to decrease, and pro-matrix metalloproteinase-2 and -9 were down-regulated (p < .01, p < .05, respectively), as was Secreted Protein Acidic and Rich in Cysteine protein expression (p < .05). Our results suggest that the cleft lip and/or cleft palate fibroblast phenotype is characterized by a tendency toward interstitial collagen deposition due to posttranslational modifications, such as decreased collagen degradation by matrix metalloproteinases and increased collagen cross-links. These findings may contribute to the knowledge of the cleft lip and/or cleft palate fibroblast phenotype and may be useful to the surgeon when considering the potential wound contraction and subsequent undesired scarring in cleft lip and/or cleft palate ocurring after the surgical closure of a cleft palate.

    Introduction In the Tessier classification, craniofacial clefts are numbered from 0 to 14 and extend along constant axes through the eyebrows, eyelids, maxilla, nostrils, and the lips. We studied a patient with bilateral cleft 10 associated with ocular abnormalities. Method Clinical report with orbital and cranial computed tomography. Results After pregnancy complicated by oligohydramnios, digoxin, and lisinopril exposure, a boy was born with facial and ocular dysmorphism. Examination at age 26 months showed bilateral epibulbar dermoids, covering half the corneal surface, and unilateral morning glory anomaly of the optic nerve. Ductions of the right eye were normal, but the left eye had severely impaired ductions in all directions, left hypotropia, and esotropia. Under anesthesia, the left eye could not be rotated freely in any direction. Bilateral Tessier cleft number 10 was implicated by the presence of colobomata of the middle third of the upper eyelids and eyebrows. As the cleft continued into the hairline, there was marked anterior scalp alopecia. Computed x-ray tomography showed a left middle cranial fossa arachnoid cyst and calcification of the reflected tendon of the superior oblique muscle, trochlea, and underlying sclera, with downward and lateral globe displacement. Discussion Tessier 10 clefts are very rare and usually associated with encephalocele. Bilateral 10 clefts have not been reported previously. In this case, there was coexisting unilateral morning glory anomaly and arachnoid cyst of the left middle cranial fossa but no encephalocele. Conclusions Bilateral Tessier facial cleft 10 may be associated with alopecia, morning glory anomaly, epibulbar dermoids, arachnoid cyst, and restrictive strabismus. PMID:20856062

    2017-05-01

    Orofacial clefts, specifically cleft lip and/or cleft palate (CL/P), are among the most common congenital anomalies. CL/P vary in their location and severity and comprise 3 overarching groups: cleft lip (CL), cleft lip with cleft palate (CLP), and cleft palate alone (CP). CL/P may be associated with one of many syndromes that could further complicate a child's needs. Care of patients with CL/P spans prenatal diagnosis into adulthood. The appropriate timing and order of specific cleft-related care are important factors for optimizing outcomes; however, care should be individualized to meet the specific needs of each patient and family. Children with CL/P should receive their specialty cleft-related care from a multidisciplinary cleft or craniofacial team with sufficient patient and surgical volume to promote successful outcomes. The primary care pediatrician at the child's medical home has an essential role in making a timely diagnosis and referral; providing ongoing health care maintenance, anticipatory guidance, and acute care; and functioning as an advocate for the patient and a liaison between the family and the craniofacial/cleft team.

    The correction of alar webbing in unilateral cleft lip nose deformity is challenging because of progressive distortions in the alar web region during the period of growth. Alar webbing is a persistent universal deformity in both the primary and secondary cleft lip noses. The purpose of this article is to study the alar web deformity in adult patients with unilateral cleft lip noses. Twenty-five patients aged 13 years and older presenting with unilateral cleft nasal deformity were included. Preoperative and postoperative measurements of the nose, along with detailed intraoperative recording of the deformed anatomy, were done. Preoperative magnetic resonance imaging was also done in selected cases. Transcolumellar open rhinoplasty was performed in all the cases, and nasal septal straightening with centralization was done. Cleft alar base augmentation was done using bone graft to restore symmetry of the nasal tripod. Both the cleft and noncleft alar cartilages were extensively mobilized from the skin and mucosal sides. The overgrown and caudally slumped cleft-side alar cartilage was resected caudally and was then resuspended in a symmetrical position with the noncleft alar cartilage. A midline-strut septal cartilage extension graft was used to restore the tip aesthetics. The skin overlying the alar web was in-rolled after semilunar cartilage resection, and skin excision was also done to restore symmetry with the opposite vestibule. The remaining secondary cleft nasal and lip deformities were corrected depending upon the specific presenting pathologic abnormality. The cleft alar cartilage was found to be caudally displaced in all the cases. The caudal border of the lateral crus was prolapsing in the cavity of the vestibule on the superomedial aspect and was tenting the skin in the area of the weak triangle, producing the characteristic alar web deformity. In the study group, the maximum width of the cleft alar cartilage at the level of the lateral crus was increased by

    Goals of treatment of orofacial cleft are to improve feeding, speech, hearing, and facial appearance. Early surgery brings faster healing, better cosmetic effect, and fewer complications. Breastfeeding rates after early surgery are unknown. Early repair of the cleft lip may influence breastfeeding rates. Research aim: The aim of this study was to evaluate breastfeeding after early repair of the cleft lip in a Baby-Friendly designated hospital. The rate of breastfeeding in newborns with cleft lip was compared to cleft lip and palate. This was a retrospective cohort study. The study group included infants with cleft lip and cleft lip and palate operated on in the first 2 weeks of life. Newborns and their mothers were supported by a team promoting breastfeeding. One hundred four infants (70 boys and 34 girls) were included. Isolated cleft lip was present in 56 (53.8%) infants, and cleft lip and palate in 48 (46.2%). Forty-four (78.6%) of the infants with a cleft lip were breastfed, 3 (5.4%) received human milk via bottle or syringe, and 9 (16.0%) were formula fed. Three (6.2%) of the infants with a cleft lip and palate were breastfed, 31 (64.6%) received human milk via bottle or Haberman feeder, and 14 (29.2%) were formula fed. The rate of breastfeeding in patients following early surgery of the cleft lip was high and comparable to the general population. The rate of breastfeeding in babies with cleft lip and palate after early repair of the cleft lip remained low.

  6. Prevalence at birth of cleft lip with or without cleft palate: data from the International Perinatal Database of Typical Oral Clefts (IPDTOC).

    As part of a collaborative project on the epidemiology of craniofacial anomalies, funded by the National Institutes for Dental and Craniofacial Research and channeled through the Human Genetics Programme of the World Health Organization, the International Perinatal Database of Typical Orofacial Clefts (IPDTOC) was established in 2003. IPDTOC is collecting case-by-case information on cleft lip with or without cleft palate and on cleft palate alone from birth defects registries contributing to at least one of three collaborative organizations: European Surveillance Systems of Congenital Anomalies (EUROCAT) in Europe, National Birth Defects Prevention Network (NBDPN) in the United States, and International Clearinghouse for Birth Defects Surveillance and Research (ICBDSR) worldwide. Analysis of the collected information is performed centrally at the ICBDSR Centre in Rome, Italy, to maximize the comparability of results. The present paper, the first of a series, reports data on the prevalence of cleft lip with or without cleft palate from 54 registries in 30 countries over at least 1 complete year during the period 2000 to 2005. Thus, the denominator comprises more than 7.5 million births. A total of 7704 cases of cleft lip with or without cleft palate (7141 livebirths, 237 stillbirths, 301 terminations of pregnancy, and 25 with pregnancy outcome unknown) were available. The overall prevalence of cleft lip with or without cleft palate was 9.92 per 10,000. The prevalence of cleft lip was 3.28 per 10,000, and that of cleft lip and palate was 6.64 per 10,000. There were 5918 cases (76.8%) that were isolated, 1224 (15.9%) had malformations in other systems, and 562 (7.3%) occurred as part of recognized syndromes. Cases with greater dysmorphological severity of cleft lip with or without cleft palate were more likely to include malformations of other systems.

    The aim of this study was to investigate the prevalence of orofacial clefts and identify the characteristics of other birth defects associated with orofacial clefts in Korea. This study used data from the Congenital Anomaly Survey conducted by the Korea Institute for Health and Social Affairs. The survey was conducted on birth defects documented during 2005 to 2006 in 2,348 medical institutes in Korea. This study was performed using data from medical insurance claims of the National Health Insurance Corporation. The prevalence of orofacial clefts was defined as the number of cases per 10,000 live births. Among the 883,184 live births, 25,335 infants had birth defects, which included 980 infants with orofacial clefts. The prevalence of total orofacial clefts in the total live births was 11.09 per 10,000, accounting for 3.9% of all birth defects. The most common orofacial cleft was cleft palate only (n=492), followed by cleft lip only (n=245) and cleft lip with cleft palate (n=243), with prevalence rates of 5.57, 2.77, 2.75 per 10,000 live births, respectively. While malformations of the circulatory system; digestive system; eyes, ears, face, and neck; and musculoskeletal system were most frequently encountered among infants with a cleft lip with or without a cleft palate, anomalies of most organ systems were notably observed among infants with cleft palate only. The prevalence of orofacial clefts in Korea was similar or slightly lower than that of other countries. This study informs present status of orofacial clefts and gives baseline data to lay the foundation stone for Korea's registry system of orofacial clefts.

    Cleft lip and cleft palate are common birth defects, affecting about one baby of every 700 born. Feeding these babies is an immediate concern and there is evidence of delay in growth of children with a cleft as compared to those without clefting. In an effort to combat reduced weight for height, a variety of advice and devices are recommended to aid feeding of babies with clefts. This review aims to assess the effects of these feeding interventions in babies with cleft lip and/or palate on growth, development and parental satisfaction. The following electronic databases were searched: the Cochrane Oral Health Group Trials Register (to 27 October 2010), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2010, Issue 4), MEDLINE via OVID (1950 to 27 October 2010), EMBASE via OVID (1980 to 27 October 2010), PsycINFO via OVID (1950 to 27 October 2010) and CINAHL via EBSCO (1980 to 27 October 2010). Attempts were made to identify both unpublished and ongoing studies. There was no restriction with regard to language of publication. Studies were included if they were randomised controlled trials (RCTs) of feeding interventions for babies born with cleft lip, cleft palate or cleft lip and palate up to the age of 6 months (from term). Studies were assessed for relevance independently and in duplicate. All studies meeting the inclusion criteria were data extracted and assessed for validity independently by each member of the review team. Authors were contacted for clarification or missing information whenever possible. Five RCTs with a total of 292 babies, were included in the review. Comparisons made within the RCTs were squeezable versus rigid feeding bottles (two studies), breastfeeding versus spoon-feeding (one study) and maxillary plate versus no plate (two studies). No statistically significant differences were shown for any of the primary outcomes when comparing bottle types, although squeezable bottles were less likely to require

    Background Cleft surgery in infants includes special risks due to the kind of the malformation. These risks can be attributed in part to the age and the weight of the patient. Whereas a lot of studies investigated the long-term facial outcome of cleft surgery depending on the age at operation, less is known about the complications arising during a cleft surgery in early infancy. Methods We investigated the incidence and severity of perioperative complications in 174 infants undergoing primary cleft surgery. The severity and the complications were recorded during the intraoperative and the early postoperative period according to the classification by Cohen. Results Our study revealed that minor complications occurred in 50 patients. Severe complications were observed during 13 operations. There was no fatal complication in the perioperative period. The risk of complications was found to be directly correlated to the body weight at the time of the surgery. Most of the problems appeared intraoperatively, but they were also followed by complications immediately after the extubation. Conclusion In conclusion, cleft surgery in infancy is accompanied by frequent and sometimes severe perioperative complications that may be attributed to this special surgical field. PMID:17280602

    A cleft palate results from incomplete fusion of the lateral palatine processes, the median nasal septum and the median palatine process. This case report describes a rare case of congenital teratoma originating from the nasal septum that may have interfered with the fusion of the palatal shelves during embryonic development, resulting in a cleft palate. An infant girl was born at 40 weeks of gestation weighing 3020 g with a complete cleft palate associated with a large central nasopharyngeal tumour. Computed tomography (CT) of the head showed a well defined mass of mixed density. The tumour was attached to the nasal septum in direct contact with the cleft palate. A biopsy confirmed the teratoma. Tumour resection was performed at 5 months, soft palate reconstruction at 7 months and hard palate closure at 14 months. There was no sign of local recurrence 1 year later. Most teratomas are benign and the prognosis is usually good. However, recurrence is not rare if germ cell carcinomatous foci are present within the teratoma. For these reasons, we advocate the use of a two-stage procedure in which closure of the cleft palate is postponed until histological examination confirms complete excision of the teratoma.

    The objective of the study was to examine the sagittal maxillary growth pattern during the mixed and permanent dentition in unilateral cleft lip and palate (UCLP) patients with unrepaired cleft palate. A total of 30 nonsyndromic UCLP patients with unrepaired cleft palate were included, 15 of whom were in mixed dentition and 15 in permanent dentition.Cephalograms were analyzed and compared in the patients with UCLP who have operatively undergone repair with both the lip and palate as well as normal subjects. The UCLP patients with unrepaired cleft palate in mixed dentition showed decreased anterior-posterior length of the maxilla. The UCLP patients with unrepaired cleft palate in permanent dentition demonstrated an almost normal maxillary growth. The operated-on patients both in mixed and permanent dentitions showed maxillary retrusion as well as decreased maxillary length. There appears that there may be the potential normal maxillary growth in UCLP patients, and early surgical repair of the cleft palate may affect sagittal maxillary growth pattern in patients with cleft.

Retrospective, observational study. Referral, urban, children's hospital Participants : Dental models and records of 270 patients were analyzed. None. Angle occlusion classification. The mean age at which occlusal classification was determined was 11 ± 0.3 years. Of the children studies, 84 were diagnosed with Class I or II occlusion, 67 were diagnosed with Class III occlusion, and 119 were lost to follow up or transferred care. Mean cleft widths were significantly larger in subjects with Class III occlusion for all measures at time of lip adhesion and definitive lip repair (P < .02). At time of palatoplasty, cleft widths were significantly greater at the alveolus (P = .025) but not at the midportion of the hard palate (P = .35) or posterior hard palate (P = .10). Cleft widths from the lip through to the posterior hard palate are generally greater in children who are diagnosed with Class III occlusion later in life. Notably, the alveolar cleft width is significantly greater at each time point for patients who went on to develop Class III occlusion. There were no significant differences in cleft widths between patients diagnosed later with Class I and Class II occlusions.

  15. Current concepts in the embryology and genetics of cleft lip and cleft palate.

    Many mechanisms underlying normal and abnormal craniofacial embryogenesis are well understood. The genetic factors that provoke abnormal development and result in orofacial clefts are not clear, but much progress has occurred in our understanding. Genes or chromosomal rearrangements on many chromosomes can lead to syndromes that include orofacial clefts. This diversity in the mechanisms that can lead to syndromic clefts highlights the fact that the processes leading to the development of the oral cavity and face are complex and sensitive to disturbances at multiple timepoints or within multiple genetic domains. As for nonsyndromic clefting, large-scale family studies are consistent with one or a few loci exerting major effects on phenotypic expression, although no single gene has been identified as a "necessary" locus for development of nonsyndromic clefts. Rather, the emerging consensus is that the genetic etiology of nonsyndromic clefting is complex, with several loci showing significant results in at least some studies. Some of these loci may be genes for susceptibility to environmental factors, some may be modifying loci, and some may be "necessary" loci. Mutations in genes that are now known to control early development are logical candidate genes for future studies of nonsyndromic orofacial clefting. Continued genetic analyses and developmental studies are crucial for eventual understanding of the complex etiology of these common congenital anomalies.

    Twenty-two consecutive children with repaired cleft lip and/or palate [isolated cleft lip (CL) 6, isolated cleft palate (CP) 7, unilateral cleft lip and palate (UCLP) 7, and bilateral cleft lip and palate 2] with a mean age of 27 months underwent spectrographic measures of tape-recorded speech (DSP Sona-Graph digital unit). Controls were 22 age- and sex-matched noncleft children. Data analyzed included (1) the Spanish vocalic variables [a, i, u, e, o]: first formant, second formant, duration, and context; (2) obstruent variables [p, t, k]: burst, voice onset time, and duration, and (3) nasal variables [m]: first formant, second formant, and duration. Statistically significant differences were observed between the CL group and the control group in the first formant of [e] and in the increase of the frequency of the [t] burst. Comparison between UCLP and controls showed differences in the second formant of [a], in the first formant of [o], and in the second formant of [o]. These results suggest a small but significant influence of either the cleft lip or its repair on lip rounding for [o] and [u]. In addition, tongue position differences were most likely responsible for the differences seen with [a] and [e]. Spectrographic differences in the current patients did not contribute to meaningful differences in speech sound development. Individualized care (orthodontics, surgery, speech therapy) in children with cleft lip and/or palate attended at specialized craniofacial units contributes to normalization of speech development.

    SUMMARY Cleft palate only (CPO) is one of the most common congenital malformations worldwide. The etiopathogenesis of CPO is not completely understood. Environmental factors, such as smoking, alcohol consumption, intake of drugs during pregnancy, advanced paternal age, have been demonstrated to be a risk of CPO, but conflicting results have also been published. Insufficient intake of folic acid during the pregnancy has been suggested to increase the risk for CPO. The demonstrated risk for siblings and the higher risk for monozygotic twins suggest a genetic etiopathogenesis for CPO. In some cases of CPO a prevalent mode of inheritance has been reported, but oligogenic models with reduced penetrance, and the risk related to environmental factors have also been proved. One of the first manifestations associated with CPO is difficulty with feeding. Aerophagia is a problem in these infants with CPO and requires more frequent burping and slower feeding. The inability to generate intraoral breath pressure due to nasal air emission in CPO children frequently manifests as articulation difficulties, particularly consonant weakness, and unintelligible speech. Hearing disorders are prevalent among individuals with CPO, as a result of chronic otitis media with effusion due to eustachian tube dysfunction. A multidisciplinary team is essential to manage the many aspects of CPO. In treating CPO, the reconstructive surgeon works in cooperation with otolaryngologists, dentists and orthodontists, speech pathologists, audiologists, geneticists, psychiatrists, maxillofacial surgeons, social workers, and prosthodontists. CPO can be considered a genetically complex disease, but new knowledge and new therapeutic approaches have greatly improved the quality of life of these children. Prenatal diagnosis is an important step in the treatment of this disease. PMID:28757935

    Muencke syndrome results from mutations in the FGFR3 gene, and although it is well recognized that the clinical presentation is variable, the important key finding includes coronal synostosis. We present a family where a mother with proven FGFR3 Pro250Arg mutation gave birth to identical twins both of whom had craniosynostosis but had coexisting bilateral cleft lip and palate. We believe that this is the first description of clefting occurring in conjunction with Muencke syndrome and so further extends the range of phenotypic variation that can occur in this syndrome.

This article describes the speech evaluation for children with cleft palate and how the results of the evaluation are used to make treatment decisions. Instrumental procedures that provide objective data regarding the function of the velopharyngeal valve, and the 2 most common methods of velopharyngeal imaging, are also described. Because many readers are not familiar with phonetic symbols for speech phonemes, Standard English letters are used for clarity.

  3. Nutritional standard for children with orofacial clefts.

    2014-01-01

    Treatment of children with orofacial clefts is a multi-stage process, usually extending over many years and requiring intervention of numerous specialists. Most of the problems in such children before the tissue reconstruction surgery are related to feeding and airway protection during swallowing. Feeding of children with orofacial clefts is the more difficult the more severe the defect is. Such children are at an increased risk of body weight deficit and malnutrition. The aim of the study is to present the nutritional standard for children with orofacial clefts. Feeding principles for children with orofacial clefts: If the clinical state of the child and the emotional state of the mother allow, children with orofacial clefts should be breastfed or bottle-fed with breast milk. If feeding with breast milk is not possible, children should receive appropriate formulas for infants. Their diet can usually be expanded at the same time as in healthy infants and should comply with the nutritional model or standard for children aged 6-12 months. Various feeding techniques are used in children with orofacial clefts, depending not only on the type of the defect, but also the experience of the institution taking care of the child. Such children may require a diet with higher calories due to their increased energy expenditure related to eating. In the case of body weight deficit and/or malnutrition resulting from inadequate diet, a change of the feeding technique should be considered, and, subsequently, a diet modification. The modification may mean an extra formula feeding (in children fed with breast milk) or earlier introduction of supplementary foods. Sometimes a different feeding method than oral feeding must be used, e.g. through a naso-gastric tube or, in extreme cases, a feeding stoma. It is of utmost importance that infants with the said defects gain the optimal body weight before the planned operation, since malnutrition may be a significant reason for delaying the

    OBJECTIVE: To examine the association between maternal smoking and non-syndromic orofacial clefts in infants. METHODS: A meta-analysis of the association between maternal smoking during pregnancy was carried out using data from 24 case-control and cohort studies. FINDINGS: Consistent, moderate and statistically significant associations were found between maternal smoking and cleft lip, with or without cleft palate (relative risk 1.34, 95% confidence interval 1.25-1.44) and between maternal smoking and cleft palate (relative risk 1.22, 95% confidence interval 1.10-1.35). There was evidence of a modest dose-response effect for cleft lip with or without cleft palate. CONCLUSION: The evidence of an association between maternal tobacco smoking and orofacial clefts is strong enough to justify its use in anti-smoking campaigns. PMID:15112010

    Objective : Children with cleft lip and palate or cleft palate only have a high incidence of conductive hearing loss from otitis media with effusion. Studies demonstrating longitudinal results are lacking. This study was undertaken to investigate long-term longitudinal hearing outcomes of children with cleft lip and/or cleft palate and cleft palate only. Design : Retrospective chart review. Setting : Clinical charts of patients born with cleft lip and palate or cleft palate only in 1985 to 1994 who were referred to the cleft team in Bergen, Norway. Study findings include 15 years of follow-up. Participants : The study population consisted of 317 children of whom 159 had nonsyndromic cleft lip and palate and 158 had nonsyndromic cleft palate. Main Outcome Measures : Pure tone average calculated from pure tone audiometry at ages 4, 6, and 15 years. Results : The median pure tone average significantly improved with increasing age. For the cleft lip and palate group, the median pure tone average at ages 4, 6, and 15 years was 16 dB hearing level (HL), 13 dB HL, and 9 dB HL, respectively (P ≤ .001). In the cleft palate group the median pure tone average at ages 4, 6, and 15 years was 15 dB HL, 12 dB HL, and 9 dB HL, respectively (P ≤ .001). There was no significant difference in the hearing levels between the two groups. Patients who had surgical closure of the palate at age 18 months had a significantly better pure tone average outcome at age 15 compared with patients who had surgery at 12 months. Conclusions : Hearing improves significantly from childhood to adolescence in patients with cleft lip and palate and cleft palate only.

  9. Community Mobilization and Awareness Creation for Orofacial Cleft Services: A Survey of Nigerian Cleft Service Providers

    2014-01-01

    Background. The opportunity to provide free surgical care for orofacial clefts has opened a new vista and is enhanced by well-informed communities who are aware of the free surgical services available to them. It is the responsibility of cleft care providers to adequately inform these communities via a combination of community mobilization and awareness creation. Methods. This was a nationwide, cross-sectional descriptive study of all orofacial cleft service providers in Nigeria using a structured, self-administered questionnaire. Results. A total of 4648 clefts have been repaired, 50.8% by the ten government-owned and 49.2% by the five nongovernment-owned organizations included in the study. The nongovernment-owned institutions seemed to be more aggressive about community mobilization and awareness creation than government-owned ones, and this was reflected in their patient turnout. Most of the organizations studied would prefer a separate, independent body to handle their awareness campaign. Conclusion. Community mobilization requires skill and dedication and may require formal training or dedicated budgets by government-owned and nongovernment-owned institutions alike. Organizations involved in cleft care provision must take community mobilization and awareness seriously if the largely unmet needs of orofacial cleft patients in Nigeria are to be tackled.

    Cleft of lip, alveolar process and palate is the most common congenital defect affecting the face. It occurs at the time of early embryogenesis as a result of disturbed differentiation of the primordial cell layer and is associated with genetic and environmental factors. The most severe type of the defect is complete cleft of the lip, alveolar process and palate, unilateral or bilateral, which is accompanied by impaired breathing, sucking, swallowing, chewing, hearing and speaking. The treatment consists in the surgical reconnection (reconstruction) of the cleft anatomical structures and their formation to gain proper appearance, occlusal conditions and speech. The part of the surgical treatment is reconstruction of alveolar bone by means of autogenic spongy bone grafting (osteoplasty). The surgery performed at the stage of mixed dentition following an orthodontic treatment is a recognized standard management modality. Its effects provide stabilization of the dental arches fixed in the orthodontic treatment, possibility of growth of permanent teeth adjoining the cleft as well as separation of the nasal and oral cavities. The grafted bone becomes a platform for the collapsed base of the ala nasi and facilitates restoration of teeth loss. In the graft healing process the volume of the regenerated bone tissue is lower than the graft volume. Methods to augment the healed bone volume are being searched for, as this factor decides substantially on successful outcome of the surgery.

    The aim of this study was to determine the incidence of cleft lip and/or cleft palate in a population uniquely from Northern Finland. The records of a total of 214 cleft patients treated between 1998-2011 at the Oulu Cleft Lip and Palate Center at the University of Oulu were assessed on a retrospective basis. Data regarding cleft type, sex and side of cleft was collected and analyzed. Family history of clefting was investigated. Cleft palate (68.7%) was most frequently found, followed by cleft lip and palate (18.7%) and cleft lip with or without alveolus (12.6%). Cleft palate occurred more frequently in females (63.3%) and cleft lip and palate was more frequently found in males (62.5%). The left side was more frequently affected in both male and female patients. Left-sided clefts were observed in 82% of patients compared to right-sided clefts in 18%. A family history of clefting was detected in 20.1% of patients. The incidence of clefts in Northern Finland is higher than the corresponding incidence in other European countries. Cleft palate was the most frequent cleft type and it was more frequent in females. In males, cleft lip and palate was more frequent. The left side was more frequently affected in both genders. One fifth of the patients had a family history of clefts.

    The Objective The aim of the study was evaluation of metal ions (nickel and chromium) released from orthodontic appliances in cleft lip and palate patients and the usefulness of non-invasive matrices (saliva and hair). Materials and Methods The material studied consisted of 100 individuals, including 59 females and 41 males of 5 to 16 years of age, which were divided into 3 groups: experimental–patients with cleft lip and palate (36 individuals, the average treatment time 5.74 years); control group–patients without cleft lip and palate, during orthodontic treatment (32 individuals, the average treatment time 1.78 years) and the control group patients without cleft lip and palate, without any orthodontic appliances (32 individuals). Samples (saliva, hair) were collected and subjects underwent a survey by questionnaire. Multi-elemental analyses of the composition of non-invasive matrices was conducted in an accredited laboratory by inductively coupled plasma spectrometry technique ICP-OES. The results were reported as mean contents of particular elements (Cd, Cr, Cu, Fe, Mn, Mo, Ni, Si) in hair and in saliva. Results The concentration of Cr, Ni, Fe and Cu ions in saliva of cleft lip and palate patients were several times higher as compared with not treated orthodontically control groups and higher than in the group with orthodontic appliances. Among the assessed matrices, hair of cleft lip and palate patients seem to be not a meaningful biomarker. Conclusion It was found that orthodontic appliances used in long-term treatment of cleft lip and palate patients do not release toxic levels of Cr and Ni ions. PMID:26544176

    The trochlear cleft is a recently described vertically oriented, low-signal cartilage lesion centered in the trough of the trochlear cartilage. The purpose of our study was to determine the incidence of clefts in an at-risk group of athletes and correlate these findings with clinical and physical examination results. Sixteen female collegiate volleyball players consented to bilateral knee evaluations, which consisted of history, physical examination, and magnetic resonance (MR) imaging. Two fellowship-trained musculoskeletal radiologists reviewed each MR study by consensus. The trochlear cartilage was considered to be either normal, at risk of developing a cleft, or meeting the previously described criteria for clefts. The Fisher exact test was used for categorical variables, and the Mann-Whitney U test was used for nonparametric continuous variable. A total of 16 athletes (32 knees; 16 women; age range, 18-22 years; mean, 19.9 years) were enrolled in the study. Four knees (13%) in 3 athletes were diagnosed with a trochlear cleft; 6 knees (19%) in 4 athletes had clefts or were at risk of developing clefts. Among those players with unilateral cartilage lesions, 67% had contralateral abnormalities (P = 0.0783). Functional outcomes and physical examination findings were within normal limits for all athletes, with no difference noted between those with and without clefts. Elite athletes have a much higher incidence of trochlear clefts than the general population and are at risk of bilateral disease. Clefts are likely to be an incidental finding at MR imaging for unrelated symptoms.

    Among the representations of congenital malformations in Moche ceramic art, cranio-facial clefts have been portrayed in pottery found in Moche burials. These pottery vessels were used as domestic items during lifetime and funerary offerings upon death. The aim of this study was to examine archeological evidence for representations of cranio-facial cleft malformations in Moche vessels. Pottery depicting malformations of the midface in Moche collections in Lima-Peru were studied. The malformations portrayed on pottery were analyzed using the Tessier classification. Photographs were authorized by the Larco Museo.Three vessels were observed to have median cranio-facial dysraphia in association with midline cleft of the lower lip with cleft of the mandible. ML001489 portrays a median cranio-facial dysraphia with an orbital cleft and a midline cleft of the lower lip extending to the mandible. ML001514 represents a median facial dysraphia in association with an orbital facial cleft and a vertical orbital dystopia. ML001491 illustrates a median facial cleft with a soft tissue cleft. Three cases of midline, orbital and lateral facial clefts have been portrayed in Moche full-figure portrait vessels. They represent the earliest registries of congenital cranio-facial malformations in ancient Peru.

    The Hedgehog (Hh) signaling pathway mediates multiple spatiotemporally-specific aspects of brain and face development. Genetic and chemical disruptions of the pathway are known to result in an array of structural malformations, including holoprosencephaly (HPE), clefts of the lip with or without cleft palate (CL/P), and clefts of the secondary palate only (CPO). Here, we examined patterns of dysmorphology caused by acute, stage-specific Hh signaling inhibition. Timed-pregnant wildtype C57BL/6J mice were administered a single dose of the potent pathway antagonist vismodegib at discrete time points between gestational day (GD) 7.0 and 10.0, an interval approximately corresponding to the 15th to 24th days of human gestation. The resultant pattern of facial and brain dysmorphology was dependent upon stage of exposure. Insult between GD7.0 and GD8.25 resulted in HPE, with peak incidence following exposure at GD7.5. Unilateral clefts of the lip extending into the primary palate were also observed, with peak incidence following exposure at GD8.875. Insult between GD9.0 and GD10.0 resulted in CPO and forelimb abnormalities. We have previously demonstrated that Hh antagonist-induced cleft lip results from deficiency of the medial nasal process and show here that CPO is associated with reduced growth of the maxillary-derived palatal shelves. By defining the critical periods for the induction of HPE, CL/P, and CPO with fine temporal resolution, these results provide a mechanism by which Hh pathway disruption can result in "non-syndromic" orofacial clefting, or HPE with or without co-occurring clefts. This study also establishes a novel and tractable mouse model of human craniofacial malformations using a single dose of a commercially available and pathway-specific drug.

    The reported birth prevalence of orofacial clefts (OFCs) varies considerably. This study describes the epidemiology of OFCs in an Australian population. We studied infants diagnosed with cleft lip, with or without cleft palate (CL±P), and cleft palate only (CPO) since 1980 and reported to the population based Western Australian Register of Developmental Anomalies. We calculated prevalence rates by sex, Aboriginal status, geographic location, and socio-economic status. Associations between clefts and folate availability, pregnancy characteristics, pregnancy outcomes, other congenital anomalies, and age at diagnosis were also investigated. From 1980 to 2009, 917 infants with CL±P (12.05 per 10,000) and from 1980 to 2004, 621 infants with CPO (10.12 per 10,000) were registered. Prevalence rates for CL±P and CPO were 1.9 and 1.3 times higher, respectively, for Aboriginal Australians. Additional anomalies were reported for 31% of infants with CL±P and for 61% with CPO; chromosomal anomalies and other specific diagnoses accounted for 46% and 66%, respectively, of those with CL±P and CPO with additional anomalies. Almost all (99.7%) children with CL±P were diagnosed before 1 year of age, but 12% of CPO diagnoses were made after 1 year of age; 94% of these diagnoses were of submucous clefts and bifid uvula. These data provide a picture of the prevalence of OFCs in WA since 1980, and provide a useful reference for OFC data in Australia and internationally. The quality and completeness of the WARDA data are high, reflected in high prevalence rates, and proportions of clefts occurring with other anomalies. Copyright © 2012 Wiley Periodicals, Inc.

    To study the risks of having other birth defects in children born with an isolated cleft palate (iCP) when the length of the cleft was taken into account. The hypothesis was that a newborn with an extensive cleft lesion may have an increased risk of other birth defects compared to a child with a less extensive cleft of the palate. All Caucasian children with iCP born between 1975 and 2005 in the southwestern region of Sweden were included. Data were collected from standardized medical records and the length of the cleft was checked on the pre-surgical dental cast for each child. A total of 343 children were born with an iCP. The incidence was 0.64/1000 live births. Thirty-four percent of children with either a total or partial iCP had other birth defects. The risk was 1.7 times higher for a total compared to a partial iCP. The two most common birth defects were congenital heart disease and intellectual disability. Ear problems related to infections were registered in 43% of cases. Fifteen percent of the children had the Pierre Robin sequence, which was analyzed as a separate variable and not included as a birth defect. The length of the iCP was found to influence the risk of having another birth defect as the total palatal clefts were more often combined with other birth defects compared to partial clefts. Careful medical check-ups are important for newborns with iCP since they have increased risks of other birth defects.

    Isis 2 satellite carried, among other ionospheric instruments an ion mass spectrometer designed to measure the composition of the ionosphere in the mass range from 1 to 64 amu. The satellite, in a nearly constant 1400-km orbit, was launched on April 1, 1971. Examples of data show a wide variation in ion composition from 99% H(+) at night near the equator to greater than 95% O(+) and N(+) in the daytime poleward of the plasmapause. Both H(+) and He(+) are observed to be streaming outward from the high-latitude regions with velocities of several kilometers per second (the polar wind), determined from phase shifts in roll modulation maximums between light and heavy ion species. During the August 1972 magnetic storm a unique ionosphere developed, consisting of N(+) as the dominant species between 55 and 80 deg invariant latitude (above the plasmapause) and N2(+), NO(+), and O2(+) at the 1000 per cu cm concentration level, whereas these molecular species are usually below the detection limit of 1 ion per cu cm in quiet times at this altitude.

Methods A total of 67 consecutive patients with non-syndromic unilateral complete cleft lip and palate (UCLP) were included from the cleft lip and palate-craniofacial center, Uppsala University Hospital, Sweden. All patients were operated by the same surgeon and treated according to the Uppsala protocol entailing: lip plasty at 3 months, soft palate closure at 6 months, closure of the residual cleft in the hard palate at 2 years of age, and secondary alveolar bone grafting (SABG) prior to the eruption of the permanent canine. Cleft size was measured on dental casts obtained at the time of primary lip plasty. Dental anomalies were registered on radiographs and dental casts obtained before bone grafting. Alveolar bone height was evaluated with the Modified Bergland Index (mBI) at 1 and 10-year follow-up. Results Anterior cleft width correlated positively with enamel hypoplasia and rotation of the central incisor adjacent to the cleft. There was, however, no correlation between initial cleft width and alveolar bone height at either 1 or 10 years follow-up. Conclusions Wider clefts did not seem to have an impact on the success of secondary alveolar bone grafting but appeared to be associated with a higher degree of some dental anomalies. This finding may have implications for patient counseling and treatment planning.

The purpose of this second part is to develop computer-based methods to quantify symmetry and to determine the correlation of these measures to clinical expectations.   A total of 35 infants with unrepaired unilateral cleft lip and 14 infant controls.   Six computer-based methods of quantifying symmetry were developed and applied to the three-dimensional images of infants with unilateral cleft lip before and after cleft lip repair and to those of controls.   Symmetry scores for cleft type, changes with surgery, and individual subjects ranked according to cleft severity were assessed.   Significant differences in symmetry scores were found between cleft types and found before and after surgery. Symmetry scores for infants with unilateral cleft lip approached those of controls after surgery, and there was a strong correlation with ranked cleft severity.   Our computer-based three-dimensional analysis of nasolabial symmetry correlated with clinical expectations. Automated processing made measurement convenient. Use of these measures may help to objectively measure cleft severity and treatment outcome.

    There is no doubt modern genetics have greatly influenced our professional and personal lives during the last decade. Uncovering genetic causes of many medical and dental pathologies is helping to narrow the diagnosis and select a treatment plan that would provide the best outcome. Importantly, having an understanding of multifactorial etiology helps direct our attention toward prevention. We now understand much better our own health problems. In some cases, we can modify our lifestyle and diet in order to prevent "environmental factors" from triggering the mutated genes inherited from our parents. Good examples are diabetes and cardiovascular diseases. If we realize we might have inherited genes for cardiovascular problems from several ancestors who had heart attacks, we already know that these genes will make us only "susceptible" for disease. Those who exercise, watch one's weight, diet, and carefully monitor one's lifestyle will very likely--though possessing "susceptibility genes"--stay healthier and, maybe, will never experience any cardiovascular problems. In principle, the same applies for craniofacial anomalies, especially for nonsyndromic cleft lip and palate. One needs to understand genetic and environmental causes of nonsyndromic orofacial clefts in order to prevent them. With all this in mind, the Pacific Craniofacial Team and Cleft Prevention Program have been established at the Department of Orthodontics, University of the Pacific Arthur A. Dugoni School of Dentistry in San Francisco. A partnership with Rotaplast International, Inc., has made it possible for the faculty, orthodontic residents, and students to participate in 27 multidisciplinary cleft medical missions in underdeveloped and developing countries by donating professional and educational services, and, last but not least, by collecting valuable data and specimens to further research.

    Nonsyndromic orofacial clefts are a common complex birth defect caused by genetic and environmental factors and/or their interactions. A previous genome-wide linkage scan discovered a novel locus for cleft lip with or without cleft palate (CL/P) at 9q22–q33. To identify the etiologic gene, we undertook an iterative and complementary fine mapping strategy using family-based CL/P samples from Colombia, USA and the Philippines. Candidate genes within 9q22–q33 were sequenced, revealing 32 new variants. Concurrently, 397 SNPs spanning the 9q22–q33 2-LOD-unit interval were tested for association. Significant SNP and haplotype association signals (P = 1.45E − 08) narrowed the interval to a 200 kb region containing: FOXE1, C9ORF156 and HEMGN. Association results were replicated in CL/P families of European descent and when all populations were combined the two most associated SNPs, rs3758249 (P = 5.01E − 13) and rs4460498 (P = 6.51E − 12), were located inside a 70 kb high linkage disequilibrium block containing FOXE1. Association signals for Caucasians and Asians clustered 5′ and 3′ of FOXE1, respectively. Isolated cleft palate (CP) was also associated, indicating that FOXE1 plays a role in two phenotypes thought to be genetically distinct. Foxe1 expression was found in the epithelium undergoing fusion between the medial nasal and maxillary processes. Mutation screens of FOXE1 identified two family-specific missense mutations at highly conserved amino acids. These data indicate that FOXE1 is a major gene for CL/P and provides new insights for improved counseling and genetic interaction studies. PMID:19779022

    The organization and management of specialized cleft lip and palate centers in developing countries are challenging because of the lack of financial resources devoted to the national health care system. The treatment of cleft lip and palate is of low priority for health care and budgets; however, gradual progress is possible. As an example of how care might be improved in the developing world, we suggest guidelines to strengthen the local cleft lip and palate centers in Brazil based on the ideal geographic distribution of cleft centers around the country, to achieve the following objectives: first, avoid patient's migration; second, facilitate patient's adherence; third, focus on a global and continuous multidisciplinary treatment; and fourth, avoid indiscriminate opening of nonprepared cleft lip and palate centers in our country. This ideal scenario would put the cleft lip and palate health attention on the right path in Brazil.

    To estimate the prevalence of oral clefts in Brazil categorized by etiology and geographical region. Case reports of oral cleft in newborns in the period 1975 - 1994 were included in the study. Data was collected using the morbidity certificates of the Hospital de Reabilitação de Anomalias Craniofaciais (Craniofacial Abnormalities Rehabilitation Hospital), Ministry of Health data (Datasus), and Fundação Instituto Brasileiro de Geografia e Estatística (Brazilian Census Bureau). There were 16,853 new cases of oral clefts, with a total prevalence of 0.19 per 1,000 births, and there was an increased prevalence every five years. The highest prevalence were observed in the Midwest, southeast, and south regions. As for the studied categories, cleft lip (or the cleft of lip and palate) was seen in 74% of the cases and isolated cleft palate was seen in 26% of them.

    Plasma microRNAs (miRNAs) have recently emerged as a new class of regulatory molecules that influence many biological functions. However, the expression profile of plasma microRNAs in nonsyndromic cleft palate (NSCP) or nonsyndromic cleft lip with cleft palate (NSCLP) remains poorly investigated. In this study, we used Agilent human miRNA microarray chips to monitor miRNA levels in three NSCP plasma samples (mixed as the CP group), three NSCLP plasma samples (mixed as the CLP group) and three normal plasma samples (mixed as the Control group). Six selected plasma miRNAs were validated in samples from an additional 16 CP, 33 CLP and 8 healthy children using qRT-PCR. Using Venn diagrams, distinct and overlapping dysregulated miRNAs were identified. Their respective target genes were further assessed using gene ontology and pathway analysis. The results show that distinct or overlapping biological processes and signalling pathways were involved in CP and CLP. Our study showed that the common key gene targets reflected functional relationships to the Notch, Wnt, phosphatidylinositol and Hedgehog signalling pathways. Further studies should examine the mechanism of the potential target genes, which may provide new avenues for future clinical prevention and therapy. PMID:27863433

    We have developed a strategy for concurrent correction of multiple secondary clefting deformities based on the model proposed by Henderson and Jackson [1] which combines several cleft-related procedures. We have expanded this concept significantly to include as many as eleven procedures. The selected procedures are dictated individually by patients' needs. The constellation of corrective cleft-related surgeries has been given the name "cleft cluster" in the interest of simplicity. We are reporting on our experience with 85 consecutive patients using this approach. All patients in this series received bone grafting of the alveolar cleft as the primary procedure, plus multiple additional procedures as necessary. None of the patients reported received primary lip or palate surgery by the authors. The average number of procedures performed was 7.2. The average hospitalization was 4.1 days. The patients have been followed from 1 to 7 yrs. The fistula recurrence rate was 8%. Average patient age was 16.8 yrs with a range of 8 to 54 yrs. This approach eliminates multiple hospitalizations and outpatient procedures, allows flexibility to individualize patient care, provides consistent results, and is cost-effective.

      Chronic ear infections are a common occurrence in children with orofacial clefts involving the secondary palate. Less is known about the middle ear status of individuals with isolated clefts of the lip, although several studies have reported elevated rates of ear infection in this group. The purpose of this retrospective study was to test the hypothesis that chronic ear infections occur more frequently in isolated cleft lip cases (n = 94) compared with controls (n = 183).   A questionnaire was used to obtain information on history of chronic ear infection. The association between ear infection status (present/absent) and cleft lip status (cleft lip case/control) was tested using both chi-square and logistic regression.   The reported occurrence of chronic ear infection was significantly greater in cleft lip cases (31%) compared with unaffected controls (11%). After adjusting for age and sex, having a cleft lip increased the odds of being positive for ear infection by a factor greater than 3 (odds ratio = 3.698; 95% confidence interval = 1.91 to 7.14). Within cleft lip cases, there was no difference in the occurrence of ear infection by defect laterality or by the type of clefting present in the family history. Although velopharyngeal insufficiency was present in 18.4% of our cleft lip sample, there was no statistical association between ear infection and abnormal speech patterns. These results may have potential implications both for the clinical management of isolated cleft lip cases and for understanding the etiology of orofacial clefting.

    Children with oral clefts show a wide range of dental anomalies, adding complexity to understanding the phenotypic spectrum of orofacial clefting. The evidence is mixed, however, on whether the prevalence of dental anomalies is elevated in unaffected relatives and is mostly based on small samples. In the largest international cohort to date of children with nonsyndromic clefts, their relatives, and controls, this study characterizes the spectrum of cleft-related dental anomalies and evaluates whether families with clefting have a significantly higher risk for such anomalies compared with the general population. A total of 3,811 individuals were included: 660 cases with clefts, 1,922 unaffected relatives, and 1,229 controls. Dental anomalies were identified from in-person dental exams or intraoral photographs, and case-control differences were tested using χ2 statistics. Cases had higher rates of dental anomalies in the maxillary arch than did controls for primary (21% vs. 4%, P = 3 × 10−8) and permanent dentitions (51% vs. 8%, P = 4 × 10−62) but not in the mandible. Dental anomalies were more prevalent in cleft lip with cleft palate than other cleft types. More anomalies were seen in the ipsilateral side of the cleft. Agenesis and tooth displacements were the most common dental anomalies found in case probands for primary and permanent dentitions. Compared with controls, unaffected siblings (10% vs. 2%, P = 0.003) and parents (13% vs. 7%, P = 0.001) showed a trend for increased anomalies of the maxillary permanent dentition. Yet, these differences were nonsignificant after multiple-testing correction, suggesting genetic heterogeneity in some families carrying susceptibility to both overt clefts and dental anomalies. Collectively, the findings suggest that most affected families do not have higher genetic risk for dental anomalies than the general population and that the higher prevalence of anomalies in cases is primarily a physical consequence of the cleft

    Congenital midline cervical cleft (CMCC) is a rare developmental defect of the anterior neck normally characterized by an atrophic mucosal plaque with a cranial nipple-like skin tag, a short caudal sinus, and may be attached to a subcutaneous fibrous cord of variable length. Clinically, patients present at an early age with, white females being the most commonly affected population. In addition to aesthetic concerns, CMCC can prevent full extension of the neck, result in micrognathia and torticollis, predispose patients to infection, and can coexist with other clefting defects or cysts. Fewer than 50 cases have been published in the English-language literature. Herein, we report a case of CMCC that also presented with a mild contracture of the right sternohyoid muscle. The embryopathogenesis, histopathology, diagnosis, and treatment of this rare condition are also discussed.

    The patterns of social integration of adults with primary and secondary groups were evaluated for 196 adult cleft subjects, their 190 siblings and 209 random controls. Results indicated that cleft adults tended to rely on the extended family for mutual aid and social activities. They also participated less frequently in voluntary associations and relied on a few one-to-one friendships. Social activities tended to be that of informal visiting patterns. While it would be inaccurate to characterize the cleft adult family as grossly different from other American families, they are a definable population experiencing some degree of limitation associated with having a cleft.

    Sternal cleft is a rare congenital malformation with little more than 100 cases published worldwide. Incomplete sternal clefting in a female newborn is the most frequent form seen. First-line treatment is the surgical defect closure in the neonatal period. Presurgical examination has to focus on common associated malformations, in particular cardiac defects. The surgical repair of sternal cleft itself shows satisfying functional and cosmetic results with low complication rates. We present the case of a 4-month-old male infant with a superior sternal cleft. PMID:26788449

    Background The association between the risk of orofacial clefts in infants and the use of corticosteroids during pregnancy is unclear from the available evidence. We conducted a nationwide cohort study of all live births in Denmark over a 12-year period. Methods We collected data on all live births in Denmark from Jan. 1, 1996, to Sept. 30, 2008. We included live births for which information was available from nationwide health registries on the use of corticosteroids during pregnancy, the diagnosis of an orofacial cleft and possible confounders. Results There were 832 636 live births during the study period. Exposure to corticosteroids during the first trimester occurred in 51 973 of the pregnancies. A total of 1232 isolated orofacial clefts (i.e., cleft lip, cleft palate, or cleft lip and cleft palate) were diagnosed within the first year of life, including 84 instances in which the infant had been exposed to corticosteroids during the first trimester of pregnancy. We did not identify any statistically significant increased risk of orofacial clefts associated with the use of corticosteroids: cleft lip with or without cleft palate, prevalence odds ratio (OR) 1.05 (95% confidence interval [CI] 0.80–1.38]; cleft palate alone, prevalence OR 1.23 (95% CI 0.83–1.82). Odds ratios for risk of orofacial clefts by method of delivery (i.e., oral, inhalant, nasal spray, or dermatologic and other topicals) were consistent with the overall results of the study and did not display significant heterogeneity, although the OR for cleft lip with or without cleft palate associated with the use of dermatologic corticosteroids was 1.45 (95% CI 1.03–2.05). Interpretation Our results add to the safety information on a class of drugs commonly used during pregnancy. Our study did not show an increased risk of orofacial clefts with the use of corticosteroids during pregnancy.

    The authors report three cases of Median Cleft of the upper lip, a clinical entity really deserving the term of "hare lip", a very ancient denomination who dates back to the Tang Dynasty and unfairly used to describe the usual lateral clefts of the lip. The denominations of "true" and "false" median cleft lips recovering respectively such different embryopathic realities as clefts of the median element with varying degrees of vertical separation and as agenesis of the fronto-nasal process accompanied with cerebral anomalies are no more used now. Median clefts of the upper lip can be included in the "neurocristopathies" by less or more precocious dysneurulation of the fronto-nasal process creating anomalies from various single midline defects of the upper lip of our three cases, to associated midline defects like in the Median Cleft face syndrome (fronto-nasal dysplasia) described by De Myer and Sedano to holoprosencephaly (arhinencephaly), which are rarely associated.

    Orofacial clefts (OFCs)--primarily cleft lip and cleft palate--are among the most common birth defects in all populations worldwide, and have notable population, ethnicity, and gender differences in birth prevalence. Interest in these birth defects goes back centuries, as does formal scientific interest; scientists often used OFCs as examples or evidence during paradigm shifts in human genetics, and have also used virtually every new method of human genetic analysis to deepen our understanding of OFC. This review traces the evolution of human genetic investigations of OFC, highlights the specific insights gained about OFC through the years, and culminates in a review of recent key OFC genetic findings resulting from the powerful tools of the genomics era. Notably, OFC represents a major success for genome-wide approaches, and the field is poised for further breakthroughs in the near future.

    2013-01-01

    Plasmodium falciparum, the causative agent of malaria, completely remodels the infected human erythrocyte to acquire nutrients and to evade the immune system. For this process, the parasite exports more than 10% of all its proteins into the host cell cytosol, including the major virulence factor PfEMP1 (P. falciparum erythrocyte surface protein 1). This unusual protein trafficking system involves long-known parasite-derived membranous structures in the host cell cytosol, called Maurer’s clefts. However, the genesis, role, and function of Maurer’s clefts remain elusive. Similarly unclear is how proteins are sorted and how they are transported to and from these structures. Recent years have seen a large increase of knowledge but, as yet, no functional model has been established. In this perspective we review the most important findings and conclude with potential possibilities to shed light into the enigma of Maurer’s clefts. Understanding the mechanism and function of these structures, as well as their involvement in protein export in P. falciparum, might lead to innovative control strategies and might give us a handle with which to help to eliminate this deadly parasite.

    To evaluate the prevalence and unmet need for cleft lip-cleft palate reconstructive surgery by using incidence. Our hypotheses were that the age of presentation to screening clinics will decrease between 2006 and 2012, and the geospatial distribution of cases will expand to a more rural catchment area. Longitudinal cross-sectional/geospatial distribution study. An online, secure database was created from intake forms for children with cleft lip-cleft palate (N=604) in Zimbabwe (2006-2012). Univariate analysis was completed. A linear regression model was fitted to test the time trend of a child's age at the time of presentation. Unique patient addresses (n=411) were matched. Maps presenting cleft diagnosis and presentation year were created with geographic information systems (GIS) software. The median age of presentation was greater for isolated cleft palate (4.2 years, n=106) than isolated cleft lip (1.5 years, n=251) and cleft lip-cleft palate (2.0 years, n=175). Cleft lip cases were mostly left sided with equal gender distribution. The overall age of presentation remained stable (P=.83). The age of children with isolated cleft palate decreased by 0.8 years per surgical trip (P=.01), suggesting the prevalence of unrepaired cleft palate is decreasing due to local and visiting surgeons. The catchment area extended to a less populous area, but clustered around Harare and Bulawayo. This study gives Zimbabwe-specific evidence that supports reports of the persistent burden of disease requiring attention. The GIS software provided data for the primary needs assessment, which will direct communication to healthcare providers and prospective patients outside of the current catchment area. 3 © 2014 The American Laryngological, Rhinological and Otological Society, Inc.

    Objective : To evaluate the effects of lip repair on maxillofacial development of patients with unilateral cleft lip with or without cleft palate. Design : Retrospective. Patients : A total of 75 patients were recruited, including 38 surgical patients with complete unilateral cleft lip and alveolus and 37 patients with complete unilateral cleft lip and palate who had lip but not palate repair. As controls, 38 patients with no cleft were selected. All subjects were divided according to two growth stages: before the pubertal peak (GS1) and after the pubertal peak (GS2). Interventions : Lateral cephalograms of all subjects were obtained. Main Outcome Measures : Cephalograms were analyzed and compared in the study and control groups. Results : The patients with unilateral cleft lip and palate in both GS1 and GS2 demonstrated an almost normal maxillary and mandibular growth with retroclined maxillary incisors. The patients with unilateral cleft lip and palate showed a shorter length of maxilla, a more clockwise-rotated mandible, and retroclined maxillary incisors. Conclusions : There was an almost normal maxillary and mandibular growth but retroclined maxillary incisors in patients with cleft lip with or without cleft palate who had received lip repair only, indicating that lip repair may not have a negative impact on the maxillofacial development and influences only the inclination of the maxillary incisors. The shorter anterior-posterior maxillary length and larger gonial angle in patients with unilateral cleft lip and palate compared with those in patients with unilateral cleft lip and alveolus suggest that these variations in maxillary and mandibular growth may be a consequence of the cleft itself.

    Background : Isolated, nonsyndromic cleft lip with or without cleft palate is a common human congenital malformation with a complex and heterogeneous etiology. Genes coding for fibroblast growth factors and their receptors (FGF/FGFR genes) are excellent candidate genes. Methods : We tested single-nucleotide polymorphic markers in 10 FGF/FGFR genes (including FGFBP1, FGF2, FGF10, FGF18, FGFR1, FGFR2, FGF19, FGF4, FGF3, and FGF9) for genotypic effects, interactions with one another, and with common maternal environmental exposures in 221 Asian and 76 Maryland case-parent trios ascertained through a child with isolated, nonsyndromic cleft lip with or without cleft palate. Results : Both FGFR1 and FGF19 yielded evidence of linkage and association in the transmission disequilibrium test, confirming previous evidence. Haplotypes of three single-nucleotide polymorphisms in FGFR1 were nominally significant among Asian trios. Estimated odds ratios for individual single-nucleotide polymorphic markers and haplotypes of multiple markers in FGF19 ranged from 1.31 to 1.87. We also found suggestive evidence of maternal genotypic effects for markers in FGF2 and FGF10 among Asian trios. Tests for gene-environment (G × E) interaction between markers in FGFR2 and maternal smoking or multivitamin supplementation yielded significant evidence of G × E interaction separately. Tests of gene-gene (G × G) interaction using Cordell's method yielded significant evidence between single-nucleotide polymorphisms in FGF9 and FGF18, which was confirmed in an independent sample of trios from an international consortium. Conclusion : Our results suggest several genes in the FGF/FGFR family may influence risk for isolated, nonsyndromic cleft lip with or without cleft palate through distinct biological mechanisms.

However the histological testing showed the absence or at least the inactive form of androgenic receptor in hair follicle of cleft site, transplantation of autologous grafts harvested from hair was successful in all six cases either into scars or the prolabium. A more natural effect was achieved by using micrografts. The positive reaction of patients proved there is a need for detailed treatment in highly outgoing individuals.

    Nonsyndromic cleft lip+/-cleft palate is a complex disease with a wide phenotypic spectrum; occult defects of the superior orbicularis oris muscle may represent the mildest subclinical form of the lip portion of the phenotype. This study used high-resolution ultrasonography to compare the frequency of discontinuities in the OO muscle in 525 unaffected relatives of individuals with nonsyndromic cleft lip+/-cleft palate versus 257 unaffected controls. OO muscle discontinuities were observed in 54 (10.3%) of the non-cleft relatives, compared to 15 (5.8%) of the controls-a statistically significant increase (P=0.04). Male relatives had a significantly higher rate of discontinuities than male controls (12.0% vs. 3.2%; P=0.01); female relatives also had a higher rate of discontinuities than female controls, but the increase was not statistically significant (8.9% vs. 7.4%; P=0.56). These data confirm the hypothesis that subepithelial OO muscle defects are a mild manifestation of the cleft lip phenotype. Identification of subepithelial OO muscle defects may be important in a clinical setting, as a means of providing more accurate recurrence risk estimates to relatives in cleft families. Furthermore, the expansion of the cleft lip+/-cleft palate phenotypic spectrum should improve the power of genetic studies. Copyright (c) 2007 Wiley-Liss, Inc.

    Objective: Natal/neonatal teeth are reported to be more common among clefts and congenital anomalies. Data exclusively among clefts is sparse. The aim was to evaluate prevalence of natal teeth among cleft lip and palate neonates and review the causes, presentation, associated anomalies, complications and management. Materials and Methods: Out of 641operated patients, records of 151 infants with cleft lip and palate with less than three months of age presented to the department of plastic and reconstructive surgery from 2005 to 2011 were reviewed. Out of which 107 were unilateral complete lip and palate (ULCP), 15 bilateral cleft lip and isolated cleft palate constituted 29. Results: Three patients among the studied records showed neonatal teeth. Two had paired central mandibular incisor teeth along with associated other anomalies and one had a single maxillary neonatal tooth. All were present in unilateral cleft lip and none of the bilateral or isolated cleft palate infants showed neonatal teeth. The overall incidence of neonatal teeth was 1.98% and 2.8% in unilateral Cleft lip. Conclusion: Our study supports the incidence of 2% natal teeth among UCLP. Involvement of mandibular central incisors in contrast to the notion that maxillary alveolus is more commonly affected suggest that it is not only the anatomical disturbance but also all those possible common multifactorial etiological factors contributing to the congenital anomalies as such. Natal/neonatal teeth are rather under-diagnosed and reported than a rare phenomenon and the prevalence is higher in certain population. Riga-Fede disease unlikely to be seen in clefts with neonatal teeth due to anatomical factors. The extraction of non mobile tooth if necessary can be done during the primary surgery for the cleft lip. PMID:24163556

    Epigenetic data could help identify risk factors for orofacial clefts, either by revealing a causal role for epigenetic mechanisms in causing clefts or by capturing information about causal genetic or environmental factors. Given the evidence that different subtypes of orofacial cleft have distinct aetiologies, we explored whether children with different cleft subtypes showed distinct epigenetic profiles. In whole-blood samples from 150 children from the Cleft Collective cohort study, we measured DNA methylation at over 450,000 sites on the genome. We then carried out epigenome-wide association studies (EWAS) to test the association between methylation at each site and cleft subtype (cleft lip only (CLO) n = 50; cleft palate only (CPO) n = 50; cleft lip and palate (CLP) n = 50). We also compared methylation in the blood to methylation in the lip or palate tissue using genome-wide data from the same 150 children and conducted an EWAS of CLO compared to CLP in lip tissue. We found four genomic regions in blood differentially methylated in CLO compared to CLP, 17 in CPO compared to CLP and 294 in CPO compared to CLO. Several regions mapped to genes that have previously been implicated in the development of orofacial clefts (for example, TBX1, COL11A2, HOXA2, PDGFRA), and over 250 associations were novel. Methylation in blood correlated with that in lip/palate at some regions. There were 14 regions differentially methylated in the lip tissue from children with CLO and CLP, with one region (near KIAA0415) showing up in both the blood and lip EWAS. Our finding of distinct methylation profiles in different orofacial cleft (OFC) subtypes represents a promising first step in exploring the potential role of epigenetic modifications in the aetiology of OFCs and/or as clinically useful biomarkers of OFC subtypes.

    Introduction The nonsyndromic orofacial cleft is the fourth most common birth defect, but in Brazil, data about the cleft epidemiology are not accurate. Objective This study aimed to describe the epidemiologic characteristics of oral cleft cases at Specialized Society Attending Cleft Patient in Sergipe State. Methods Data were obtained from patients' medical records in relation to the following characteristics: age; gender; race; origin; cleft type; additional malformations and/or complications; prenatal accomplishment; treatment applied. For diagnosis analysis, it was noted if mothers had received prenatal care and if they had ultrasonography performed and if the cleft was viewed in it. Results We observed a prevalence of male gender (54%). Age between 0 and 4 years old was most prevalent (53%), and pheoderma race was observed in 47%. Transincisive foramen cleft was found in 52.3% of the individuals. The prevalence of pre- and transincisive foramen cleft was higher in men (66.3 and 55.7%), women accounted for 65.0% of postincisive foramen, and atypical facial cleft (0.3%) occurred in one case. Associated malformations and complications were present in 12% of patients. Prenatal care was reported by 48% of the mothers. Conclusion In this study male gender was the most affected, and 0 to 4 years was the most frequent age group. Transincisive foramen cleft type was most frequently encountered. Prenatal care was reported by most mothers. So, this study found that early treatment is a reality in SEAFESE (Service Specializing in Cleft Care of Sergipe), and consequently the chances of successful integration of the child to society will be better.

    ABSTRACT Aim We present a novel surgical technique for repair of persistent and symptomatic cyclodialysis clefts refractory to conservative or minimally invasive treatment. Background Numerous surgical techniques have been described to close cyclodialysis clefts. The current standard approach involves intraocular repair of cyclodialysis clefts underneath a full-thickness scleral flap. Technique Our technique employs intraoperative use of a direct gonioscope to guide a nonpenetrating surgical repair. Subsequently, a significantly less invasive, nonpenetrating technique utilizing a partial-thickness scleral flap can be performed that reduces potential risks associated with intraocular surgery. The direct gonioscope is also used for confirmation of adequate surgical closure of the cyclodialysis cleft prior to completion of surgery. This technique has been successfully carried out to repair traumatic chronic cyclodialysis clefts associated with hypotony in two patients. There were no significant adverse events as a result of using this technique. Conclusion The novel technique described increases the likelihood of successful and permanent repair of cyclodialysis clefts with resolution of symptoms associated with hypotony, through direct intraoperative visualization of the cleft. Clinical significance Gonioscopically guided nonpenetrating cyclodialysis cleft repair offers significant benefits over previously described techniques. Advantages of our technique include gonioscopic cleft visualization, enabling accurate localization of the area requiring repair, and subsequent confirmation of adequate closure of the cleft. Using a partial-thickness scleral flap is also less invasive and reduces risks associated with treatment of this potentially challenging complication of ocular trauma.

    This study compares hospital-based care and associated charges among children with cleft lip, cleft palate, or both, and identifies subgroups generating the greatest cumulative hospital charges. The authors conducted a retrospective cohort study of cleft lip, cleft palate, or cleft lip and palate who underwent initial surgery from 2006 to 2008 in four U.S. states. Primary outcome was hospital-based care-emergency, outpatient, inpatient-within 4 years of surgery. Regression models compared outcomes and classification tree analysis identified patients at risk for being in the highest quartile of cumulative hospital charges. The authors identified 4571 children with cleft lip (18.2 percent), cleft palate (39.2 percent), or cleft lip and palate (42.6 percent). Medical comorbidity was frequent across all groups, with feeding difficulty (cleft lip, 2.4 percent; cleft palate, 13.4 percent; cleft lip and palate, 6.0 percent; p < 0.001) and developmental delay (cleft lip, 1.8 percent; cleft palate, 9.4 percent; cleft lip and palate, 3.6 percent; p < 0.001) being most common. Within 30 days of surgery, those with cleft palate were most likely to return to the hospital (p < 0.001). Hospital-based care per 100 children within 4 years was lowest among the cleft lip group, yet comparable among those with cleft palate and cleft lip and palate (p < 0.001). Cumulative 4-year charges, however, were highest among the cleft palate cohort (cleft lip, $56,966; cleft palate, $106,090; cleft lip and palate, $91,263; p < 0.001). Comorbidity, diagnosis (cleft lip versus cleft palate with or without cleft lip), and age at initial surgery were the most important factors associated with the highest quartile of cumulative hospital charges. Cleft lip and palate children experience a high rate of hospital-based care early in life, with degree of medical comorbidity being a significant burden. Understanding this relationship and associated needs may help deliver more efficient, patient

    Ion concentrations, flow velocities, and fluxes, measured by the ion mass spectrometer on the Isis 2 satellite for periods around the solstices and equinoxes of 1971 and 1972, have been used in a study of the polar wind morphology during magnetically quiet times. The results confirm the major tenets of polar wind theories; namely, that an upward flow of both H(+) and He(+) ions exists at all times over the entire polar region; H(+) fluxes are of the order of 10 to the 8th ions/sq cm s in both summer and winter polar regions. O(+) is the dominant ion specie at 1400-km altitude in regions of strong H(+) flows, and H(+) is depleted over the entire region where the polar wind flows. H(+) fluxes tend to be lower in winter than in summer, whereas He(+) fluxes are a factor of 10 higher in winter and tend to follow the neutral helium concentration near the F2 maximum. The latter agree well with model calculations of flux in the winter but lie above the model values by a factor of 2 in the summer. H(+) fluxes also agree well with ion flow models.

    Background The bone graft for the alveolar cleft has been accepted as one of the essential treatments for cleft lip patients. Precise preoperative measurement of the architecture and size of the bone defect in alveolar cleft has been considered helpful for increasing the success rate of bone grafting because those features may vary with the cleft type. Recently, some studies have reported on the usefulness of three-dimensional (3D) computed tomography (CT) assessment of alveolar bone defect; however, no study on the possible implication of the cleft type on the difference between the presumed and actual value has been conducted yet. We aimed to evaluate the clinical predictability of such measurement using 3D CT assessment according to the cleft type. Methods The study consisted of 47 pediatric patients. The subjects were divided according to the cleft type. CT was performed before the graft operation and assessed using image analysis software. The statistical significance of the difference between the preoperative estimation and intraoperative measurement was analyzed. Results The difference between the preoperative and intraoperative values were -0.1±0.3 cm3 (P=0.084). There was no significant intergroup difference, but the groups with a cleft palate showed a significant difference of -0.2±0.3 cm3 (P<0.05). Conclusions Assessment of the alveolar cleft volume using 3D CT scan data and image analysis software can help in selecting the optimal graft procedure and extracting the correct volume of cancellous bone for grafting. Considering the cleft type, it would be helpful to extract an additional volume of 0.2 cm3 in the presence of a cleft palate. PMID:23094242

    To establish the prevalence of congenital heart diseases (CHDs) in cleft patients, the type of cleft and the presence of a syndrome were coded in 220 patients. A Doppler echocardiogram with color-flow mapping (DE) was obtained in all patients. Mean age was 112.0 +/- 101.2 months (range, 1-576 months), and 56.8% (125) were males. Cleft lip and palate occurred in 144 patients (65.5%), cleft lip in 40 (18.2%), and cleft palate in 36 (16.4%). Cleft palates were more frequent among females. Twenty-four CHDs were diagnosed in 21 of 220 patients (9.5%): 7 mitral valve prolapses, 6 atrial septal defects, 4 patent ductus arteriosus, 3 ventricular septal defects, 2 cases of tetralogy of Fallot, 1 pulmonary stenosis, and 1 bicuspid aortic valve. The presence of CHD did not correlate with the type of cleft. Syndromes occurred in 28 patients (12.7%), and this association was higher among patients with a cleft palate.

    Our aim is to introduce and validate a new oral cleft classification system based on prenatal ultrasound for use by professionals in daily practice. During a 3-year period (2011-2014), all cases of prenatal oral cleft diagnosed by ultrasound were retrospectively reviewed. A new prenatal ultrasound classification system was introduced. For the purpose of validation, prenatal ultrasound images of oral cleft types were described according to the new classification system and were compared with postnatal findings by reviewing medical records. A total of 103 fetuses with oral cleft were identified by ultrasound. The mean gestation time at detection was 20.4 weeks (95% confidence intervals: 20.0-20.7). The association between oral cleft and other anomalies varied by cleft type; types 2b/3b and 4 were most frequently associated with other anomalies. The measure of agreement between the prenatal and postnatal findings showed a Kappa value of 0.63 (95% confidence intervals: 0.52-0.75), demonstrating the accuracy of this new classification system. A new prenatal oral cleft classification system is presented. This system appears to be accurate, and it shows the variation in the risk of associated anomalies for each cleft type. We expect that ultrasonographers will be able to use the new classification in daily practice. © 2015 John Wiley & Sons, Ltd.

    Context: Cleft palate is the second most common birth defect and is considered as a challenge for pediatric plastic surgeons. There is still a general lack of a standard protocol and patients often require multiple surgical interventions during their lifetime along with disappointing results. Evidence Acquisition: PubMed search was undertaken using search terms including 'cleft palate repair', 'palatal cleft closure', 'cleft palate + stem cells', 'cleft palate + plasma rich platelet', 'cleft palate + scaffold', 'palatal tissue engineering', and 'bone tissue engineering'. The found articles were included if they defined a therapeutic strategy and/or assessed a new technique. Results: We reported a summary of the key-points concerning cleft palate development, the genes involving this defect, current therapeutic strategies, recently novel aspects, and future advances in treatments for easy and fast understanding of the concepts, rather than a systematic review. In addition, the results were integrated with our recent experience. Conclusions: Tissue engineering may open a new window in cleft palate reconstruction. Stem cells and growth factors play key roles in this field. PMID:25593724

    Though India has an estimated population of one million untreated cleft patients, facilities for its treatment have been limited and are not evenly distributed across the country. Furthermore, a paucity of committed cleft surgeons in fewer hospitals to provide quality surgical treatment to these patients, poverty, illiteracy, superstitions and poor connectivity in some remote regions severely limit the chances of an average cleft lip patient born in India from receiving rational and effective comprehensive treatment for his/her malady. The Smile Train Project with its singular focus on cleft patients started its philanthropic activities in India in the year 2000. It made hospitals and included clefts surgeon equal partners in this programme and helped them treat as many cleft patients as they possibly could. The Project encouraged improvement of the training and infrastructure in various centres across the length and breadth of the region. The Project received an unprecedented success in terms of growth of number of centres, cleft surgeons and quantum of cleft patients reporting for treatment. The G S Memorial Hospital is one such partner hospital. It started innovative outreach programmes and took a holistic view of the needs of these patients and their families. With the support of the Smile Train, it has not only succeeded in providing treatment to more than 14,500 patients in 5 years, but has also devised innovative outreach programmes and seamlessly incorporated salient changes in the hospital system to suit the needs of the target population.

      Many societies and organizations are using social media to reach their target audience. The extent to which parents of patients with craniofacial anomalies use social media has yet to be determined. The goal of this study is to characterize and describe the use of social media by the parents of children with cleft lip and palate as it pertains to the care of their child.   Parents or guardian of all patients presenting for initial consultation regarding a child's congenital cleft anomaly were contacted by phone or mail to complete a survey regarding their use of social media vis-à-vis their child's cleft anomaly. Participants were asked to answer a 19-question survey.   Thirty-two families were contacted and 25 surveys were completed. Ninety-two percent of respondents used social media to learn about their child's diagnosis. Facebook (76%) and blogs (24%) were the most commonly accessed social media outlets, followed by Instagram (8%). Education about the diagnosis and treatment of cleft pathology (87%) was the most common reason for accessing social media, followed by companionship and support (56%), and advice about perioperative care (52%). Almost half (43%) of parents used social media to obtain information on their caregiver and treatment team, and 26% of parents used information gained on social media to guide their decision on where to seek care.   Social media is a readily available resource, one that will certainly shape the experiences of our patients and families for years to come.

    The objectives of the ground-based observations in support of the SCIFER are: Acquire and display ionospheric conditions prior to launch to aid in the establishment of launch criteria in real time. Observers at both stations participated in real-time visual interpretation. Solar wind data from IMP-8 and WIND were acquired and interpreted in real time. Telephonic and data links were established at the observatory for the launch window period. Ground-based observatory countdown and launch criteria were developed. 2) Relate optical and magnetic ionospheric signatures observed from the ground to magnetospheric boundaries in the energetic particle flux measured at the payload. The energetic electron trapping boundary was found to correspond to the equatorward edge of the discrete auroral arcs forming the dayside aurora. The energetic electron trapping boundary was found to correspond to the poleward edge of pulsating aurora. The pulsating aurora was found to correspond to one second bursts of energy-dispersed electrons originating in the equatorial plane. Pulsations at larger intervals corresponded to travel times to the conjugate region and return. The pulsating aurora was also directly linked to the geomagnetic pulsations and traveling magnetic vortices, all occurring equatorward of the trapping boundary. 630 nm emission corresponding to less than 10 eV electron precipitation was observed equatorward of the trapping boundary (L=15) and ascribed to photoelectrons from the sunlit conjugate region. 3) Aid in the interpretation of time/space incongruities in the rocket data. The motion of the payload conjugate across the aurora showed that the payload passed over three distinct arc systems on the poleward side of the trapping boundary. These results were reported in a series of articles to be printed in Geophysical Research Letters on June 15, l996.

    Little information is available concerning the prevalence of caries among patients with oral clefts in Eastern China. Consecutive patients aged 6-18 with oral clefts were recruited. Patients were stratified into 2 groups according to their ages, namely Group I with aged 6-12 and Group II with aged 13-18. For each age group, the children were further divided into three subgroups according to the types of oral clefts they had: cleft lip/cleft lip and alveolus (CL), cleft palate only (CP), and cleft lip and palate (CLP). Dental caries were examined by using the decayed, missing, and filled index for primary teeth (dmft) and Decay, Missing and Filled index for Permanent teeth (DMFT) according to criteria of the World Health Organization. 268 eligible patients with oral clefts were included in the study. The mean DMFT for Group I was 1.77 (SD2.58) while that for Group II was 6.96 (SD4.35). The mean DMFT was statistically significant different between the age group I and age group II (t=12.21, P<0.05). In Group I, the dmft scores was 4.68 (SD3.67) for CL group, while that for the CP group was 7.36 (SD3.93), and that for the CLP group was 5.72 (SD 3.87). The mean dmft was no statistically significant different among cleft types (F=3.13, P>0.05). Also in Group I, the mean DMFT was 1.56 (SD2.18) for CL group, while that for the CP group was 1.24 (SD 1.81) and that for the CLP group was 2.08 (SD2.96). There were no statistically significant different in mean DMFT among different cleft types (F=1.09, P>0.05). In Group II, the mean DMFT was 6.06 (SD3.97) for CL group while that for the CP group was 7.71 (SD 4.94) and that for the CLP group was 7.05 (SD4.32). No significant difference was shown in the mean DMFT among different cleft groups (CL, CP, and CLP) (F=0.55, P>0.05). During assess the prevalence of dental caries among Eastern Chinese with oral clefts; the study confirmed that the prevalence of caries was increased with increasing age for oral clefts patients.

    Objectives. To find clinical decisions on cleft treatment based on randomized controlled trials (RCTs). Method. Searches were made in PubMed, Embase, and Cochrane Library on cleft lip and/or palate. From the 170 articles found in the searches, 28 were considered adequate to guide clinical practice. Results. A scarce number of RCTs were found approaching cleft treatment. The experimental clinical approaches analyzed in the 28 articles were infant orthopedics, rectal acetaminophen, palatal block with bupivacaine, infraorbital nerve block with bupivacaine, osteogenesis distraction, intravenous dexamethasone sodium phosphate, and alveoloplasty with bone morphogenetic protein-2 (BMP-2). Conclusions. Few randomized controlled trials were found approaching cleft treatment, and fewer related to surgical repair of this deformity. So there is a need for more multicenter collaborations, mainly on surgical area, to reduce the variety of treatment modalities and to ensure that the cleft patient receives an evidence-based clinical practice.

    Second branchial cleft cysts (also called cervical lymphoepithelial cysts) usually present in adulthood, and cosmesis of surgical access is an important issue. This study was performed to assess the feasibility and outcome of a retroauricular approach for removing second branchial cleft cysts. Eight patients underwent removal of second branchial cleft cysts using a retroauricular approach. All 8 second branchial cleft cysts were removed successfully, and the wounds healed uneventfully. None of the patients suffered from weakness of the great auricular nerve. Marginal nerve palsy did not occur postsurgery. Average follow-up period was 14.5 months (range, 6-20 months) with no tumor recurrence. The incision scars were invisible. Second branchial cleft cyst resection using a retroauricular approach is a feasible method that provides an acceptable cosmetic outcome.

    Stillman's cleft is a mucogingival triangular-shaped defect on the buccal surface of a root with unknown etiology and pathogenesis. The aim of this study is to examine the Stillman's cleft obtained from excision during root coverage surgical procedures at an histopathological level. Harvesting of cleft was obtained from two periodontally healthy patients with a scalpel and a bevel incision and then placed in a test tube with buffered solution to be processed for light microscopy. Microscopic analysis has shown that Stillman's cleft presented a lichenoid hand-like inflammatory infiltration, while in the periodontal patient an inflammatory fibrous hyperplasia was identified. Stillman's cleft remains to be investigated as for the possible causes of such lesion of the gingival margin, although an inflammatory response seems to be evident and active from a strictly histopathological standpoint.

    2015-01-01

    Palatal necrosis after palatoplasty in patients with cleft palate is a rare but significant problem encountered by any cleft surgeon. Few studies have addressed this disastrous complication and the prevalence of this problem remains unknown. Failure of a palatal flap may be attributed to different factors like kinking or section of the pedicle, anatomical variations, tension, vascular thrombosis, type of cleft, used surgical technique, surgeon's experience, infection, and malnutrition. Palatal flap necrosis can be prevented through identification of the risk factors and a careful surgical planning should be done before any palatoplasty. Management of severe fistulas observed as a consequence of palatal flap necrosis is a big challenge for any cleft surgeon. Different techniques as facial artery flaps, tongue flaps, and microvascular flaps have been described with this purpose. This review article discusses the current status of this serious complication in patients with cleft palate. PMID:26273624

    Background: Cleft lip and palate surgery abroad is devoid of global consensus regarding standards of therapy, follow-up, and outcome. Cleft surgery in Nepal during a 10-year sustained program provided the opportunity to inform on the need for such standards. Methods: Medical records were evaluated from the cleft clinic at Sushma Koirala Memorial Hospital, Sankhu, Kathmandu, Nepal, from 1997 to 2007. Four groups were identified for analysis: total cohort, total surgical cohort (TSC), primary program patients (PPP; patients had not been operated on before), and nonprimary program patients (non-PPP; patients operated on elsewhere before). Patient demographics, diagnostic, primary and secondary surgery (corrective surgery), and follow-up were evaluated. Results: One thousand forty-five patients were eligible for surgery. Three hundred twenty-three of 1,045 patients (30.9%) did not seek treatment, although scheduled for surgery. One thousand two hundred one procedures were performed in 722 patients [TSC; 845 PPP (70.4%); 356 non-PPP (29.64%)]. Corrective procedures were performed in 257 of 1,201 [3.5% (30 of 845 procedures in 509 patients) PPP vs 63.7% (227 of 356 procedures in 213 patients) non-PPP]. One hundred six lips were completely reoperated on (1 PPP vs 105 non-PPP), and 42 palates underwent a total revision (5 PPP vs 37 non-PPP). The surgical outcome of the TSC group in terms of complication rate was similar to the one in developed countries. Conclusions: The high rate of corrective surgery reveals the need for global regulatory mechanisms and the need for nongovernmental organizations to introduce strategies for delivering sustained cleft care until achieving full rehabilitation. The World Health Organization should establish standards for cleft care delivered in less developed countries. PMID:27579235

    Presurgical nasoalveolar moulding (PNAM) is a non-surgical method of reshaping the cleft lip, alveolus, palate and the nose to minimize the severity of the cleft deformity, before primary cheiloplastyand palatoplasty. In this context, PNAM proves to be an invaluable asset in the management of unilateral cleft lip and palate. The study was conducted to evaluate the efficacy of PNAM in the management of unilateral cleft lip and palate with the following objectives: (1) To assess and compare the degree of reduction in the size of cleft palate and alveolus (pre-PNAM and post-PNAM). (2) To evaluate and compare the improvement in columellar length and correction of columellar deviation (pre-PNAM and post-PNAM). (3) To assess the changes in the position of the alar base and the alar cartilages. Prospective study. A prospective study consisting of, which included 20 patients with complete unilateral cleft lip and palate was conducted. The age at the start of PNAM treatment of the infants ranged from 2 to 44 days of age reporting to our institute between December 2011 and August 2013. All the patients underwent PNAM therapy before primary cheiloplasty at 6 months of age; clinical parameters were assessed pre- and post-therapy using photographs and dental study models of the maxilla. Student's t-test for paired comparisons. Results of the study showed a promising reduction in the cleft size before the surgery, significant improvement in nasal symmetry, including the columellar length on the cleft side. PNAM is a valuable adjunct to our surgical armamentarium in dealing with the challenges of primary closure of unilateral cleft lip and palate thereby enhancing the overall surgical outcome. The advantages of this method include the simplicity of the procedure and improving the quality of surgical repair, particularly in obtaining tension free muscle closure in unilateral clefts.

    The aesthetic aspects of the cleft lip nasal deformity have been appreciated for over a century, but the functional implications have remained largely underappreciated or misunderstood. This study describes the frequency and severity of nasal obstructive symptoms among children with cleft lip and/or cleft palate, addressing the hypotheses that age, cleft type, and severity are associated with the development of nasal obstructive symptoms. Children with nonsyndromic cleft lip and/or cleft palate and a comparison group of unaffected children born from 1997 to 2003 were identified through the North Carolina Birth Defects Monitoring Program and birth certificates. Nasal airway obstruction was measured using the validated Nasal Obstruction Symptom Evaluation scale. The survey was completed by parental proxy for 176 children with cleft lip and/or cleft palate and 333 unaffected children. Nasal obstructive symptoms were more frequently reported in cleft lip with cleft palate compared with unaffected children (p < 0.0001); children who had isolated cleft lip with or without alveolus and isolated cleft palate were not statistically different from unaffected children. Patients with unilateral cleft lip with cleft palate were found to be more severely affected than bilateral cases. Nasal obstruction was observed in early childhood, although severity worsened in adolescence. This population-based study reports a high prevalence of nasal obstructive symptoms in children with cleft lip and/or cleft palate based on type and severity of the cleft. The authors encourage cleft teams to consider using this or similar screening methods to identify which children may benefit from functional rhinoplasty. Risk, I.

    To compare effects of secondary cleft procedures on alar base position and nostril morphology. Retrospective review. Multidisciplinary cleft clinic at tertiary center. Seventy consecutive patients with unilateral clefts were grouped according to secondary procedure. Alveolar bone graft versus total lip takedown with anatomic muscle repair versus single-stage total lip with cleft septorhinoplasty (nose-lip) versus rhinoplasty alone. Anthropometric measurements were recorded from pre- and postoperative photographs. Ratios of cleft to noncleft side were compared within and across groups pre- and postoperatively using parametric and nonparametric tests. Within the bone graft group, no differences were seen postoperatively in alar base position in long-term follow-up. The total lip group demonstrated greater symmetry at the alar base (P < .001), increased vertical lip dimension (P < .001), and decreased nostril height (P = .004) postoperatively. Within the nose-lip group, increased vertical dimension and alar base support (P < .001) were also seen postoperatively. Across groups, the single-stage nose-lip group demonstrated greatest alar base symmetry on worm's-eye view (P < .04). Alar base asymmetry in patients with unilateral clefts may be related to soft tissue deficiency and was not affected by alveolar bone grafting. Total lip takedown with anatomic muscle reapproximation was associated with increased alar base symmetry and vertical lip dimension on cleft to noncleft side. Greatest symmetry at the alar base was seen following single-stage nose-lip reconstruction, which may be an effective technique for correcting the secondary cleft lip nasal deformity.

    Abstract Nonsyndromic cleft lip with or without cleft palate (nsCL/P) is among the most common human birth defects with multifactorial etiology. Here, we present results from a genome-wide imputation study of nsCL/P in which, after adding replication cohort data, four novel risk loci for nsCL/P are identified (at chromosomal regions 2p21, 14q22, 15q24 and 19p13). On a systematic level, we show that the association signals within this high-density dataset are enriched in functionally-relevant genomic regions that are active in both human neural crest cells (hNCC) and mouse embryonic craniofacial tissue. This enrichment is also detectable in hNCC regions primed for later activity. Using GCTA analyses, we suggest that 30% of the estimated variance in risk for nsCL/P in the European population can be attributed to common variants, with 25.5% contributed to by the 24 risk loci known to date. For each of these, we identify credible SNPs using a Bayesian refinement approach, with two loci harbouring only one probable causal variant. Finally, we demonstrate that there is no polygenic component of nsCL/P detectable that is shared with nonsyndromic cleft palate only (nsCPO). Our data suggest that, while common variants are strongly contributing to risk for nsCL/P, they do not seem to be involved in nsCPO which might be more often caused by rare deleterious variants. Our study generates novel insights into both nsCL/P and nsCPO etiology and provides a systematic framework for research into craniofacial development and malformation. PMID:28087736

    Cleft lip and palate is a common human birth defect, and its causes are being dissected through studies of human populations and through the use of animal models. Mouse models in particular have made a substantial contribution to our understanding of the gene pathways involved in palate development and the nature of signaling molecules that act in a tissue-specific manner at critical stages of embryogenesis. Related work has provided further support for investigating the role of common environmental triggers as causal covariates. PMID:15199400

    Velopharyngeal insufficiency (VPI) can occur in the setting of an unrepaired or repaired cleft lip and palate. The rate of VPI has been documented as high as 33% in some studies with higher rates of recurrences following surgery associated with genetic syndromes such as 22q11.2 deletions. The primary cause of VPI in these groups is still identified as the anatomic abnormalities of the velum. In this review, the anatomy and physiology of the velum are discussed along with genetic mutations associated with VPI. PMID:27617110

    Background Cleft lip with or without cleft palate is one of the most common congenital anomalies that affect the oro-facial region. The aim of the study was to determine the period prevalence, pattern and perceptions of cleft lip and cleft palate in children born between 2005 and 2010 in two hospitals in Kisoro District, Uganda. Methods The study involved a retrospective review of medical records of mothers who delivered live babies between January 2005 and December 2010 in Kisoro Hospital and St. Francis Hospital, Mutolere in Kisoro District. Key informant interviews of mothers (n = 20) of the children with cleft lip and/or clip palate and selected medical staff (n = 24) of the two hospitals were carried out. The data were analysed using descriptive statistics. Results Over the 6 year period, 25,985 mothers delivered live babies in Kisoro Hospital (n = 13,199) and St. Francis Hospital, Mutolere (n = 12,786) with 20 babies having oro-facial clefts. The overall period prevalence of the clefts was 0.77/1,000 live births. Sixty percent (n = 12) of children had combined cleft lip and palate and the same proportion had clefts on the left side of the face. More boys were affected than girls: 13 versus 7. About 45% of mothers were hurt on realizing that they had delivered a child with an oro-facial cleft. Forty percent of mothers indicated that a child with oro-facial cleft was regarded as an outcast. About 91.7% (n = 22) of the medical staff reported that these children were not accepted in their communities. Surgical intervention and psychosocial support were the management modalities advocated for by most respondents. Conclusion/recommendations The period prevalence of combined cleft lip and palate in two hospitals in Kisoro District was comparable to some findings elsewhere. Cleft lip and cleft palate are a medical and psychosocial problem in Kisoro District that calls for sensitization and counseling of the families and communities of the affected children

    Nonsyndromic orofacial cleft is a common birth defect with a complex etiology, including multiple genetic and environmental risk factors. Recent whole genome analyses suggested associations between nonsyndromic orofacial cleft and up to 18 genetic risk loci (ABCA4, BMP4, CRISPLD2, GSTT1, FGF8, FGFR2, FOXE1, IRF6, MAFB, MSX1, MTHFR, MYH9, PDGFC, PVRL1, SUMO1, TGFA, TGFB3, and VAX1), each of which confers a different relative risk in different populations. We evaluate the nonsynonymous variants in these 18 genetic risk loci in nonsyndromic orofacial clefts and normal controls to clarify the specific variants in Taiwanese population. We evaluated these 18 genetic risk loci in 103 cases of nonsyndromic orofacial clefts and 100 normal controls using a next-generation sequencing (NGS) customized panel and manipulated a whole-exon targeted-sequencing study based on the NGS system of an Ion Torrent Personal Genome Machine (IT-PGM). IT-PGM data processing, including alignment with the human genome build 19 reference genome (hg19), base calling, trimming of barcoded adapter sequences, and filtering of poor signal reads, was performed using the IT platform-specific pipeline software Torrent Suite, version 4.2, with the plug-in "variant caller" program. Further advanced annotation was facilitated by uploading the exported VCF file from Variant Caller to the commercial software package Ion Reporter; the free online annotation software Vanno and Mutation Taster. Benign or tolerated amino acid changes were excluded after analysis using sorting intolerant from tolerant and polymorphism phenotyping. Sanger sequencing was used to validate the significant variants identified by NGS. Furthermore, each variant was confirmed in asymptomatic controls using the Sequenom MassARRAY (San Diego, CA, USA). We identified totally 22 types of nonsynonymous variants specific in nonsyndromic orofacial clefts, including 19 single nucleotide variants, 2 deletions, and 1 duplication in 10 studied

    2014-01-01

    Summary: Craniofacial clefts involve all soft tissue and skeletal elements throughout the cleft. Usefulness of tissue expansion in craniofacial clefts is reported. Surgery for a complex type of facial clefts is more difficult and more extensive than for a simple one. We experienced a primary case of complex facial clefts (Tessier No. 2 and 12 on the right and 3, 11, and 5 on the left). Soft-tissue closure of all clefts could be completed by using 4 tissue expanders and 7 operations. Because multiple tissue deficiencies and abnormalities exist in craniofacial clefts, especially complex type, a planned, staged, sequential approach by tissue expansion is necessary to produce ideal results.

    One of the unexpected results of the Cassini mission was the discovery of negative ions at altitudes between 950 and 1400 km in Titan's ionosphere with masses up to 10,000 amu/q [Coates, A.J., Crary, F.J., Lewis, G.R., Young, D.T., Waite Jr., J.H., Sittler Jr., E.C., 2007. Discovery of heavy negative ions in Titan's ionosphere. Geophys. Res. Lett., 34, L22103, doi:10.1029/2007GL030978; Waite Jr., J.H., Young, D. T., Coates, A. J., Crary, F. J., Magee, B. A., Mandt, K. E., Westlake, J. H., 2008. The Source of Heavy Organics and Aerosols in Titan's Atmosphere, submitted to Organic Matter in Space, Proceedings IAU Symposium no. 251]. These ions are detected at low altitudes during Cassini's closest Titan encounters by the Cassini plasma spectrometer (CAPS) electron spectrometer. This result is important as it is indicative of complex hydrocarbon and nitrile chemical processes at work in Titan's high atmosphere. They may play a role in haze formation and ultimately in the formation of heavy particles (tholins), which fall through Titan's atmosphere and build up on the surface. During Cassini's prime mission negative ions were observed on 23 Titan encounters, including 7 in addition to those reported by Coates et al. [Coates, A.J., Crary, F.J., Lewis, G.R., Young, D.T., Waite Jr., J.H., Sittler Jr., E.C., 2007. Discovery of heavy negative ions in Titan's ionosphere. Geophys. Res. Lett., 34, L22103, doi:10.1029/2007GL030978]. Here, we also examine the altitude and latitude dependence of the high-mass negative ions observed in Titan's ionosphere, and we examine the implications of these results. We find that the maximum negative ion mass is higher at low altitude and at high latitudes. We also find a weaker dependence of the maximum mass on solar zenith angle.

    Facial clefts are rare congenital malformations. In the literature these are sometimes reported in combination with limb malformations, especially ring constrictions. This article describes three children with facial clefts and limb ring constrictions with various expressions. The first case has a lateral cleft with associated limb malformations. This combination has, to our knowledge, not yet been reported. The literature about facial clefting and the amniotic band syndrome and the possible etiology of clefting and constrictions in these cases are discussed.

    To examine the birth prevalence, gender distribution, and pattern of surgical intervention for clefts in Canada (1998 to 2007). Also to highlight the difficulties associated with studying the epidemiology of clefts using the current data collection mechanisms. Epidemiologic data acquired from the Canadian Institute for Health Information. Population-based study in Canada 1998 to 2007. All live births with an International Classification of Diseases (9th or 10th revision) diagnostic code for cleft palate or for cleft lip with or without cleft palate or with a surgical intervention code for repair of cleft lip or cleft palate. Birth prevalence, gender distribution, and pattern of surgical intervention. There were 3,015,325 live births in Canada (1998 to 2007). The mean birth prevalence was 0.82 per 1000 live births for cleft lip with or without cleft palate and 0.58 per 1000 live births for cleft palate. The birth prevalence of cleft lip with or without cleft palate was significantly higher in boys, with a stable boy to girl ratio of 1.75:1. Cleft palate was significantly greater in girls; however, the boy to girl ratio decreased from 0.97:1 in 1998 to 0.59:1 in 2007. The median age of repair in Canada from 1998 to 2007 was 4.7 months for cleft lip and 11.6 months for cleft palate. Thirty percent of patients underwent cleft palate repair after age 1. The birth prevalence of cleft palate and cleft lip with or without cleft palate is stable in Canada. An increasing birth prevalence of cleft palate in girls is suggested. The timing of surgical intervention is consistent with current standards. The challenges associated with collecting these data in Canada are discussed.

    A new generation of surveys will soon map large fractions of sky to ever greater depths and their science goals can be enhanced by exploiting cross correlations between them. In this paper we study cross correlations between the lensing of the CMB and biased tracers of large-scale structure at high z. We motivate the need for more sophisticated bias models for modeling increasingly biased tracers at these redshifts and propose the use of perturbation theories, specifically Convolution Lagrangian Effective Field Theory (CLEFT). Since such signals reside at large scales and redshifts, they can be well described by perturbative approaches. We compare our model with the current approach of using scale independent bias coupled with fitting functions for non-linear matter power spectra, showing that the latter will not be sufficient for upcoming surveys. We illustrate our ideas by estimating σ8 from the auto- and cross-spectra of mock surveys, finding that CLEFT returns accurate and unbiased results at high z. We discuss uncertainties due to the redshift distribution of the tracers, and several avenues for future development.

    2015-01-01

    Clefts that occur in children are a special topic. Avoiding risk factors, and also an early diagnosis of cleft possibility can result in minimizing or avoiding them. If on the other hand when clefts occur they require a long-term, multistage specialized treatment. Etiology of clefts seems to be related to many factors. Factors such as genetic, environmental, geographic and even race factors are important. Identification of risk factors can lead to prevention and prophylactic behaviors in order to minimize its occurrence. Exposure to environmental factors at home and work that lead to cleft predisposition should not be disregarded. It seems that before planning a family it would be wise to consult with doctors of different specializations, especially in high-risk families with cleft history in order to analyze previous lifestyle. Clefts are very common in hereditary facial malformations and are causing a lot of other irregularities in the head and neck region. In this paper after a brief papers review authors present socio-geographic, environmental and also work place related factors that are influencing pregnant women condition and should be taken under serious consideration.

    The criterion standard of alveolar cleft repair is iliac crest bone graft before secondary canine eruption. Tooth eruption has never been shown to occur in synthetic bone substitute, and there is no ideal autologous bone graft for primary repair. This prospective study evaluated alveolar cleft grafting with a calcium substitute before primary canine eruption. Ten consecutive patients with complete cleft lip, palate, and unilateral alveolar cleft with reasonably aligned arches were grafted beginning in January 2003 to March 2007. Mean age at surgery was 10.4 months. Follow-up ranged from 3 to 7 years. Radiologic evaluation of alveolar ridge was performed at the age of 4.All 10 patients were operated on by the same surgeon using the same technique, that is, conservative elevation of nasal, oral, and anterior alveolar mucosal flaps around the cleft, closure of nasal and oral flaps, placement of 1 to 3 mL of calcium substitute paste or crystals in the pocket, and closure of the anterior alveolar mucosa. All 10 patients healed without complication. Clinical evaluation revealed a well-healed arch with primary canine growth in the area of the previous cleft. Adequate normal bone formation and often a descending secondary canine were radiologically confirmed. Calcium substitutes offer significant advantages over other biomaterials as well as autologous bone grafts particularly in the primary alveolar cleft reconstruction. Our study has shown for the first time that teeth can erupt through this material, which turns into a normal functioning bone in the alveolar ridge.

    Cleft lip and/or palate (CL/P) represent the most common congenital anomalies of the face, corresponding to approximately 65% of all malformations of the craniofacial region. to describe unusual clinical cases of non-syndromic CL/P (CL/PNS), diagnosed in a reference service in Minas Gerais, Brazil, and correlate these alterations with possible risk factors. we carried out a retrospective study, between the years of 1992 and the 1st half of 2009, from medical records. Among the 778 cases of CL/PNS diagnosed in the period of 17 years, 5 (0.64%) were unusual CL/PNS, and all patients were male. It was found that among the 5 patients, 2 had incomplete right cleft lip with incomplete cleft palate, 2 were affected by left incomplete cleft lip and incomplete cleft palate, and 1 had a cleft lip and palate associated with complete right cleft palate. Risk factors such as consanguinity, maternal smoking and alcohol consumption, medication usage during pregnancy, history of abortion and/or stillbirths and maternal diseases were not associated with unusual CL/PNS. This study described 5 unusual cases of CL/PNS in a Brazilian population; no associations with the risk factors analyzed were seen. It also confirmed the unusualness of the prevalence of such alterations.

      Since the 1960s, multiple studies have reported a tendency toward hypertelorism in individuals with nonsyndromic orofacial clefts (OFCs). However, the association between specific cleft types and increased interorbital distance has been inconsistent. Using three-dimensional (3D) surface imaging, we tested whether different forms of clefting showed evidence of increased interorbital distance.   Intercanthal and outercanthal distances and intercanthal indices were calculated from 3D facial surface images of 287 individuals with repaired OFCs. Raw measurements were converted to sex and age-normalized Z-scores. Mean Z-scores for individuals with cleft lip (CL), cleft lip and palate (CLP), and cleft palate (CP) were compared with reference normative values (controls) and one another directly using t tests and analysis of variance.   The CLP group showed a significant increase in intercanthal width (P = .001) and intercanthal index (P < .001) compared with reference norms. The CP group showed a significant decrease (P < .001) in outercanthal width. The CL group showed no difference from reference norms. The proportion of clinically hyperteloric individuals was generally low but highest in the CLP group (7.4%). Cleft severity had little effect on interorbital spacing.   Individuals with CLP exhibited on average a tendency toward mild hypertelorism, driven primarily by an increase in intercanthal distance. This tendency was not seen in CL or CP.

    Congenital cardiac anomalies are common in trisomy 21, and transthoracic echocardiogram within the first month of life is recommended. While a cleft mitral valve associated with atrioventricular septal defect has been well defined in this population, the prevalence of isolated mitral valve cleft has not been previously reported. The aim of our study was to define the occurrence of isolated mitral cleft in the first echocardiogram of patients with trisomy 21. This retrospective chart review examined echocardiographic data on all Trisomy 21 patients <1 year of age obtained during January 1, 2010, to May 1, 2014, at our institution. Images were reviewed by one of the authors with no knowledge of the official diagnosis. In addition to evaluation for isolated mitral valve cleft, data obtained included presence of additional congenital heart defects and need for surgical intervention. A total of 184 patients (median age 5 days) were identified. Isolated mitral cleft was identified in 12 patients (6.5 %). Four were diagnosed retrospectively (33 %). Only one had mitral regurgitation on initial echocardiogram. Seven required surgery for closure of ventricular septal defects. Isolated mitral cleft is present in an important number of neonates with Trisomy 21. Mitral regurgitation is often absent in the neonatal period and should not be used as a reliable indicator of absence of valve abnormality. Careful attention should be directed toward the mitral valve during the first echocardiogram to exclude an isolated cleft, which can lead to progressive mitral regurgitation.

    Cleft palate repair leaves full-thickness mucosal defects on the palate. Healing might be improved by implantation of a mucosal substitute. However, the genetic and phenotypic deviations of cleft palate cells may hamper tissue engineering. The aim of this study was to construct mucosal substitutes from cleft palate cells, and to compare these with substitutes from normal palatal cells, and with native palatal mucosa. Biopsies from the palatal mucosa of eight children with cleft palate and eight age-matched control individuals were taken. Three biopsies of both groups were processed for (immuno)histochemistry; 5 were used to culture mucosal substitutes. Histology showed that the substitutes from cleft-palate and non-cleft-palate cells were comparable, but the number of cell layers was less than in native palatal mucosa. All epithelial layers in native palatal mucosa and mucosal substitutes expressed the cytokeratins 5, 10, and 16, and the proliferation marker Ki67. Heparan sulphate and decorin were present in the basal membrane and the underlying connective tissue, respectively. We conclude that mucosal cells from children with cleft palate can regenerate an oral mucosa in vitro.

    Introduction: Unfavorable results in unilateral and bilateral cleft lip repair are often easy to spot but not always easy to prevent as to treat. We have tried to deal with the more common problems and explain possible causes and the best possible management options from our experience. Unilateral cleft lip repair: Unfavorable results immediately after repair involve Dehiscence and Scaring. Delayed blemishes include vermillion notching, a short lip, deficiency in the height of the lateral vermillion on the cleft side, white roll malalignment, oro-vestibular fistula, the cleft lip nose deformity, a narrow nostril and a “high-riding” nostril. We analyze the causes of these blemishes and outline our views regarding the treatment of these. Bilateral cleft lip: Immediate problems again include dehiscence as also loss of prolabium or premaxilla. Delayed unfavorable results are central vermillion deficiency, a lip that is too tight, bilateral cleft lip nose deformity, problems with the premaxilla and maxillary growth disturbances. Here again we discuss the causation of these problems and our preferred methods of treatment. Conclusion: We have detailed the significant unfavorable results after unilateral and bilateral cleft lip surgery. The methods of treatment advocated have been layer from our own experience.

    Objective To analyse hospital admissions in the first 2 years of life among children with cleft lip and/or palate in England. Design Analysis of national administrative data of hospital admissions. Setting National Health Service hospitals. Patients Patients born alive between 1997 and 2008 who underwent surgical cleft repair. Outcome measures Number of admissions, including the birth episode, and days spent in hospital were examined. Children were analysed according to cleft type and whether or not they had additional congenital anomalies. Results 10 892 children were included. In their first 2 years, children without additional anomalies (n=8482) had on average 3.2 admissions and 13.2 days in hospital, which varied from 2.6 admissions and 9.2 days with cleft lip to 4.7 admissions and 19.7 days with bilateral cleft lip and palate (BCLP). Children with additional anomalies (n=2410) had on average 6.7 admissions and 51.4 days in hospital, which varied from 6.4 admissions and 48.5 days with cleft palate to 8.8 admissions and 67.5 days with BCLP. The mean number and duration of cleft-related admissions was similar in children without (1.6 admissions and 6.4 days) and in those with additional anomalies (1.5 admissions and 8.5 days). 35.2% of children without additional anomalies had at least one emergency admission, whereas the corresponding figure was 67.3% with additional anomalies. Conclusions The burden of hospital care in the first 2 years of life varied according to cleft type and presence of additional anomalies. However, cleft-specific hospital care did not differ between children with and without additional anomalies. PMID:23968774

    The aim of this study was to determine the incidence of facial clefting in Cambridge, UK, using multiple resources of ascertainment and to relate the findings to antenatal ultrasound screening (AUS) detection rates. AUS records from an obstetric ultrasound department, post-natal records from the regional craniofacial unit, and autopsy reports of foetuses over 16 weeks' gestational age from a regional pathology department from 1993 to 1997 were retrospectively reviewed. Cross-referencing between the three data sets identified all cases of facial clefts. Of 23,577 live and stillbirths, 30 had facial clefts. AUS detected 17 of these. Sixteen of the 30 had isolated facial clefts. Others had associated anomalies, chromosomal defects, or syndromes. Percentages and confidence intervals were calculated from the above data. Twenty-one resulted in live births, seven terminations, and two foetal deaths. Overall, detection rate by AUS was 65 percent [67 percent isolated cleft lip, 93 per cent cleft lip and palate (CLP), and 22 percent isolated cleft palate], with no false positives. The incidence of facial clefts was 0.127 percent (95 percent confidence interval 0.089-0.182 percent); the incidence for isolated CLP was lower than previously reported: 0.067 percent (0.042-0.110 percent). With one exception, all terminations were in foetuses with multiple anomalies. The figures presented will enable joint CLP clinics to give parents information of termination rates. The study allows pre-pregnancy counselling of families previously affected by clefting about the reliability of AUS detection rates.

  1. The lack of isolated palatal clefts in Czech Gypsies.

    Orofacial clefts are usually divided into three basic types: isolated cleft lip (CL), cleft lip and palate (CLP) and isolated cleft palate (CP). The incidence of specific cleft types in a population and their relative numbers show specific differences between ethnic groups and races. However, there are no available data about the incidence and relative numbers of orofacial cleft types (CL, CLP, CP) in the gypsy ethnic group. The aim of this study was to compare relative numbers of specific types of orofacial clefts between the Czech gypsy and non-gypsy populations. We conducted a retrospective epidemiological study using a set of all living patients with orofacial clefts born in the Czech Republic from 1964 until 2002. The cleft patients were subdivided into three groups: 5304 non-gypsy children, both parents of whom were non-gypsies (NN), 98 gypsy children, both parents of whom were gypsies (GG) and 18 children with one parent non-gypsy and one parent gypsy (NG). The relative number of isolated CP was 37.1% in NN children. However, the relative number of CP was significantly reduced to 5.1% (P < 0.01) in the GG group. Conversely, the relative number of CLP was higher (P < 0.01) in the GG group (62.2%) in comparison to the NN group (39.2%). The tendency to decrease in the relative number of CP and increase in the relative number of CLP was also apparent in the NG group, but not so well expressed. We hypothesize that the decrease in CP and increase in CLP and CL in gypsies might be caused by their genetic predis-position to CL. Since the CP originates later than CL during embryonic development, some CP arise in embryos with already existing CL giving rise to CLP. Consequently, the missing isolated CP might be hidden in the group of CLP patients postnatally.

    Objective: The study was conducted to examine the patients with abnormalities of cleft lip and/or palate and its association with different types of malocclusion. Materials and Methods: This descriptive study was done among 168 patients with abnormalities of cleft lip and/or palate. Angle's classification of malocclusion was applied for assessment of occlusion as Class I, Class II, and Class III. The types of oral clefts classification such as cleft lip unilateral and cleft lip bilateral, cleft palate (CP), unilateral cleft lip with palate (UCLP) and bilateral cleft lip with palate (BCLP) was considered. Chi-square test was applied to analyze the data at P < 0.05. Results: The study showed different categories of clefts patients as cleft lip (81), CP (31), and both cleft lip and palate (53). The occurrence of unilateral cleft lip (44) was maximum among the sample followed by UCLP (39), and bilateral cleft lip (31). Maximum subjects with Class II (10.7%) and Class III (4.9%) malocclusion were seen with unilateral cleft lip deformities. None of the patients with UCLP had Class III malocclusion. Conclusion: Cleft lip was the most commonly observed deformity and high frequency of Class II and III malocclusion was evident. Therefore, patients with such abnormalities should be screened timely.

    Objective To evaluate the outcomes of care for children by type of oral cleft. Design Data were collected through structured telephone interviews during 2003 in Iowa with mothers of 2- to 12-year-old children with oral clefts. Interviews with mothers of children with clubfoot and statewide data on Iowa children were used for comparison. Participants Participants included mothers of children in Iowa born between 1990 and 2000 with nonsyndromic oral clefts. Children were identified by the statewide Iowa Registry for Congenital and Inherited Disorders. Main Outcome Measures Rating of cleft care, severity of condition, health status, esthetic outcome, speech, and school performance were evaluated by type of oral cleft. Results Children with cleft lip and palate were most likely to have their clefts rated as very severe. Children with palatal involvement were reported to have a lower health status and were almost twice as likely to be identified as having a special health care need compared with either children with cleft lip or children statewide. Children with cleft lip had more esthetic concerns; children with palatal involvement had the most speech concerns. Conclusions Although mothers generally believed their children had received high-quality care, ratings of the children’s current health status and outcomes of care varied significantly by type of cleft (cleft lip, cleft palate, and cleft lip and palate). Differences observed in this population-based study support the proposition that cleft type should be considered when examining outcomes of care for children with oral clefts. PMID:17105335

    2016-01-01

    Cortical ‘clefts’ (schizencephaly) and cortical ‘bumps’ (polymicrogyria) are malformations arising due to defects in postmigrational development of neurons. They are frequently encountered together, with schizencephalic clefts being lined by polymicrogyria. We present the case of an eight-year-old boy who presented with seizures. Imaging revealed closed lip schizencephaly, polymicrogyria and a deep ‘incomplete’ cleft lined by polymicrogyria not communicating with the lateral ventricle. We speculate that hypoperfusion or ischaemic cortical injury during neuronal development may lead to a spectrum of malformations ranging from polymicrogyria to incomplete cortical clefts to schizencephaly.

    Understanding eustachian tube physiology and anticipating probable eustachian tube dysfunction is an important component of cleft palate management. This article provides a brief summary of the otologic physiology and issues that may be of concern to cleft palate management. It is of critical importance not only to provide primary closure of the cleft palate, but also to recognize that along with speech, hearing has a critical component to the educational and social success of all individuals.

    The concept of presurgical nasoalveolar moulding (PNM) was developed to improve the aesthetic result of surgically corrected cleft lip. This paper presents the method of fabrication of PNM appliance and the case of a 30-day-old neonate with unilateral cleft lip in whom nasal moulding was performed. Treatment was initiated at 30 days and continued for 60 days after which the surgical correction of cleft lip was performed. Significant improvement in aesthetics and symmetry of the nose was achieved at the end of the treatment. PMID:24928928

    The treatment of cleft in the soft palate can be achieved essentially by surgical reconstruction or prosthetic obturation. The goals of prosthetic intervention are to prevent food and liquid leakage into the nose and to improve speech intelligibility by ensuring functional velopharyngeal port closure. In this report, the prosthetic management of a 5-year-old child with soft palatal cleft is presented. The impression of the cleft was taken with tissue conditioner, Visco -gel, TM (De Trey, Amalgamated Dental London) and the pharyngeal obturator (speech bulb) was made in clear acrylic resin. Patient tolerated the appliance well and was referred to speech therapist for speech articulation.

    We did not previously provide LOD scores for linkage assuming heterogeneity, as suggested by Ott for the linkage analysis of cleft lip with or without cleft palate (CL/P) and BCL3, ApoC2, and D19S178 in the paper by Stein et al. The results from analysis using the HOMOG program, allowing for heterogeneity under the reduced penetrance model, gave a maximum LOD score of 1.85 for ApoC2, 0.41 for BCL3, 0.03 for D19S178, and 1.72 for multipoint analysis in the interval. For the affecteds-only model, the values are 1.96 for ApoC2, 0.41 for BCL3, 0.01 for D19S178, and 1.44 for the multipoint analysis. 8 refs.

    We revisited 42 families with two or more cleft affected siblings that participated in previous studies and collected complete dental information. Genotypes from 1489 single nucleotide polymorphism (SNP) markers located in 150 candidate genes/loci were reanalyzed. Two sets of association analyses were carried out. First we ran the analysis solely on the cleft status. Second we assigned affection to any cleft or dental anomaly (tooth agenesis, supernumerary teeth, and microdontia), and repeated the analysis. Significant over-transmission was seen for a SNP in ANKS6 (rs4742741, 9q22.33; p=0.0004) when a dental anomaly phenotype was included in the analysis. Significant over-transmission was also seen for a SNP in ERBB2 (rs1810132, 17q21.1; p=0.0006). In the clefts only data, the most significant result was also for ERBB2 (p=0.0006). Other markers with suggestive p-values included IRF6 and 6q21-q23 loci. In contrast to the above results, suggestive over-transmission of markers in GART, DPF3, and NRXN3 were seen only when the dental anomaly phenotype was included in the analysis. These findings support the hypothesis that some loci may contribute to both clefts and congenital dental anomalies. Thus, including dental anomalies information in the genetics analysis of cleft lip and palate will provide new opportunities to map susceptibility loci for clefts. PMID:18978678

    The objective of this research was to identify potential biological pathways associated with non-syndromic cleft lip with or without cleft palate (NSCL/P), and to explore the potential biological mechanisms underlying these associated pathways on risk of NSCL/P. This project was based on the dataset of a previously published genome-wide association (GWA) study on NSCL/P (Beaty et al. 2010). Case-parent trios used here originated from an international consortium (The Gene, Environment Association Studies consortium, GENEVA) formed in 2007. A total of 5,742 individuals from 1,908 CL/P case-parents trios (1,591 complete trios and 317 incomplete trios where one parent was missing) were collected and genotyped using the Illumina Human610-Quad array. Candidate pathways were selected using a list of 356 genes that may be related to oral clefts. In total, 42 candidate pathways, which included 1,564 genes and 40,208 SNPs were tested. Using a pathway-based analysis approach proposed by Wang et al (2007), we conducted a permutation-based test to assess the statistical significance of the nominal p-values of 42 candidate pathways. The analysis revealed several pathways yielding nominally significant p-values. However, controlling for the family wise error rate, none of these pathways could retain statistical significance. Nominal p-values of these pathways were concentrated at the lower tail of the distribution, with more than expected low p-values. A permutation based test for examining this type of distribution pattern yielded an overall p-value of 0.029. Thus, while this pathway-based analysis did not yield a clear significant result for any particular pathway, we conclude that one or more of the genes and pathways considered here likely do play a role in oral clefting.

    To evaluate and describe the swallowing function in children after laryngeal cleft repair. Ten-year (2002-2012) retrospective chart review. Academic tertiary care pediatric otolaryngology practice. Records of 60 children who had surgical repair of laryngeal cleft (ages 2 weeks-14 years) and postoperative functional endoscopic evaluation of swallowing or videofluoroscopic swallow studies were examined retrospectively. Twenty-nine children had one postoperative swallow evaluation, 19 children had two, 4 children had three, 5 children had four, and 3 children had five. Median time to the first evaluation was 10.8 weeks (interquartile range [IQR]: 36.5, 231). On the final swallow evaluation, 34 (57%) children demonstrated normal swallowing parameters, 12 (20%) children showed penetration, and 14 (23%) children showed aspiration. Forty-three (72%) children were able to take everything by mouth normally or with minor behavioral modifications, 11 (18%) children required thickened fluids, and six (10%) children were kept nil per os (NPO). Mean improvement on the penetration-aspiration (pen-asp) scale was 2.13. On multivariable analysis, neurodevelopmental issues and gastronomy tube use were associated with the need for NPO status. Despite a high rate of surgical success, a substantial minority of children have persistent swallowing dysfunction after laryngeal cleft repair. Swallowing dysfunction after repair is multifactorial and arises from concomitant neurologic, anatomic, or other comorbidities that contribute to oropharyngeal and pharyngeal dysphagia. Based on our results, we recommend a testing schedule for postoperative swallowing evaluations after cleft repair. © 2014 The American Laryngological, Rhinological and Otological Society, Inc.

    2011-03-01

    The purposes of the study were to compare the temporal characteristics of nasalization between speakers with cleft palate with or without cleft lip and normal adult speakers and to investigate the relationship between acoustic temporal measures and perceived nasality. Fifteen speakers with cleft palate with or without cleft lip and 15 speakers without cleft palate aged 13 to 45 years participated in this study. Two listeners judged the degree of nasality in speakers with cleft palate with or without cleft lip. Two distinct acoustic energies derived from the mouth and nose were recorded simultaneously while speakers were producing the speech tasks /pimip/, /pamap/, and /pumup/. Absolute and proportional measures related to nasalization duration were obtained. Speakers with cleft palate with or without cleft lip exhibited more extensive acoustic nasalization in the time domain than did speakers without cleft palate with or without cleft lip. Speakers without cleft palate with or without cleft lip showed larger nasalization-duration ratios in the high vowel contexts than in the low vowel context. Speakers with cleft palate with or without cleft lip did not exhibit distinct differences in nasalization-duration ratios among the vowel contexts. The acoustic measurements reflecting temporal patterns of oral-nasal acoustic impedance were related to the perception of hypernasality. These results suggest that the speakers with cleft palate with or without cleft lip showed longer duration of acoustic nasalization than speakers without cleft palate with or without cleft lip. Temporal characteristics of acoustic nasalization grew longer as the degree of perceived hypernasality increased. The positive correlation between temporal measures of acoustic nasalization and degree of perceived nasality suggests that temporal measures of nasalization would provide supplementary diagnostic information in relation to the degree of hypernasality.

    Introduction: Cleft lip and palate, the most common developmental deformity, is seen worldwide and the etiology involves a combination of genetic and environmental factors. The purpose of this study was to determine the maternal risk factors associated with the development of cleft lip and cleft palate. Materials and Methods: We conducted a case control study at the Women’s Hospital in Culiacan, Mexico. Medical records were analyzed, including patients who delivered babies with and without cleft lip and cleft palate from January 2010 to December 2015. Multiple variables were analyzed, including gestational age, weight at birth, the use of folic acid and multivitamins during pregnancy, smoking, alcohol abuse, the use of recreational drugs, history of sexually transmitted infections, marital status, socioeconomic status, education, and nutritional status. Results: We found that the maternal risk factors with the strongest association for the development of cleft lip and cleft palate were the following: patients who were not taking folic acid during pregnancy [OR 3.27, 95% CI 1.32-8.09], P=0.00; patients who were not taking vitamin supplementation during pregnancy [OR 2.6, 95% CI 1.19-7.27], P=0.02; smoking during pregnancy [OR 2.05, 95% CI 1.23-3.41], P=0.01; and alcohol abuse during pregnancy [OR 1.90, 95% CI 1.17-3.08], P=0.03. Conclusions: The main risk factors associated with the development of cleft lip and cleft palate in a Mexican population at the Women’s hospital in Culiacan, Sinaloa, Mexico were smoking, alcohol abuse, and patients not taking folic acid and multivitamins during pregnancy.

    The goal of this study was to describe the clinical characteristics and treatment outcomes of patients with hemifacial microsomia (HFM) and cleft lip/palate (CL/P), and to compare them to a historic cohort of patients with non-syndromic CL/P treated at the same centre. A retrospective review of patients with HFM and CL/P was performed; the main outcome measures assessed were cleft type/side, surgical outcome, midfacial retrusion, and speech. Twenty-six patients (13 male, 13 female; mean age 22.7±14.9, range 1-52 years) with cleft lip with/without cleft palate (CL±P) were identified: three with cleft lip (12%), two with cleft lip and alveolus and an intact secondary palate (8%), and 21 with cleft lip and palate (CLP) (81%; 15 unilateral and six bilateral). Four patients (19%) had a palatal fistula after palatoplasty. Twelve of 22 patients aged >5 years (55%) had midfacial retrusion and two (9%) required a pharyngeal flap for velopharyngeal insufficiency (VPI). Fisher's exact test demonstrated a higher frequency of complete labial clefting (P=0.004), CLP (P=0.009), midfacial retrusion (P=0.0009), and postoperative palatal fistula (P=0.03) in HFM compared to non-syndromic CL±P. There was no difference in VPI prevalence. This study revealed that patients with HFM and CL±P have more severe forms of orofacial clefting than patients with non-syndromic CL±P. Patients with HFM and CL±P have more severe midfacial retrusion and a higher palatal fistula rate compared to patients with non-syndromic CL±P.

    We revisited 42 families with two or more cleft-affected siblings who participated in previous studies. Complete dental information was collected to test the hypothesis that dental anomalies are part of the cleft phenotype spectrum, and can provide new opportunities for identification of cleft susceptibility genes. Genotypes from 1489 single nucleotide polymorphism markers located in 150 candidate genes/loci were reanalyzed. Two sets of association analyses were carried out. First, we ran the analysis solely on the cleft status. Second, we assigned affection to any cleft or dental anomaly (tooth agenesis, supernumerary teeth, and microdontia) and repeated the analysis. Significant over-transmission was seen for a single nucleotide polymorphism in ankyrin repeat and sterile alpha motif domain containing 6 (rs4742741, 9q22.33; P = 0.0004) when a dental anomaly phenotype was included in the analysis. Significant over-transmission was also seen for a single nucleotide polymorphism in ERBB2 (rs1810132, 17q21.1; P = 0.0006). In the clefts only data, the most significant result was also for ERBB2 (P = 0.0006). Other markers with suggestive P values included interferon regulatory factor 6 and 6q21-q23 loci. In contrast to the above results, suggestive over-transmission of markers in GART, DPF3, and neurexin 3 were seen only when the dental anomaly phenotype was included in the analysis. These findings support the hypothesis that some loci may contribute to both clefts and congenital dental anomalies. Thus, including dental anomalies information in the genetics analysis of cleft lip and palate will provide new opportunities to map susceptibility loci for clefts.

    To determine if Chinese individuals with nonsyndromic cleft lip with or without cleft palate (CL/P) display more bilateral asymmetry than do their unaffected relatives. A case-control study of 313 individuals with CL/P from Shanghai, China, with 201 unaffected relatives as controls. Size-adjusted asymmetry scores were defined by data on middle-finger length, palm length, palpebral fissure width, and ear length. Case-control comparisons used a multivariate repeated measures analysis of variance, paired t tests, and the Wilcoxon signed rank test. The ear-length measure showed a significant increase in fluctuating asymmetry (FA) in individuals with CL/P compared with their unaffected relatives, which was most pronounced in the female cleft lip and palate subgroup (p = .04). No other measures showed any increase in FA. Evidence was found for increased FA, as measured by overall ear length, in Chinese individuals with nonsyndromic CL/P, compared with their unaffected family members. The use of bilateral measurements other than dermatoglyphics may prove to be a valuable means of assessing overall developmental stability in individuals with developmental malformations and in their families.

The healthcare process emphasizes interdisciplinary teamwork at each stage of the planning of treatment and services with the primary goal of achieving patient satisfaction and ability to live normally in society. The first 5 years are particularly important, with a focus on quality of care and ability to adapt to the environment before entering school. To study the treatment of patients with cleft lip and palate in Tawanchai center in the 4-5 year age range. A retrospective study of the clinical records was led, concerning the 123 cleft lip and cleft palate patients aged 4-5 years under treatment in Tawanchai center, Srinagarind Hospital. Data was collected during three months from October to December 2011, using the admission records of the interdisciplinary team. Percentages and mean values were calculated from these data. 120 of the 123 patients were operated, giving a ratio of 97.56%. 108 cases were under government universal health coverage regime, corresponding to 87.80% of cases. 74 cases (60.16%) presented both cleft lip and palate condition, and an average of 5-night stay in hospital per person. Medical services by the interdisciplinary team were provided as follows: (1) of 30 patients with cleft lip aged 3-4 months, 30 (100%) received pre and post-surgery care counseling, 29 (96.67%) received surgery; (2) of 19 patients with cleft palate aged 10-18 months, 17 (89.47%) received treatment information, pre and postsurgery counseling and were operated according to the protocols; (3) of 74 patients with cleft lip and palate, 53 (71.62%) received counseling for pre and post-surgery care for lip repair at the age of 3-4 months, 52 (70.27%) were operated following the protocols, while at the age of 10-18 months 63 patients (85.14%) received treatment information, pre and postsurgery care counseling

    Epidemiologic studies involving birth defects are extremely sensitive to phenotype accuracy and precision. We devised a case review and classification protocol for a project to study school achievement in children with idiopathic, nonsyndromic orofacial clefts to improve the reliability of phenotypic classification from the statewide birth defects registry. Surveillance-program abstraction data and medical records at the birth or treating hospitals were used when available. Exclusion criteria included: median cleft lip; Tessier cleft; premaxillary agenesis; presence of a recognizable syndrome, phenotype, association, or sequence (other than Robin sequence); clefts with other malformations not considered to be normal or common variants in the newborn; and cases with documented or suspected genetic or teratogenic causes. Of 712 children identified with orofacial clefts, 153 were excluded, leaving 559 nonsyndromic orofacial cleft cases of unknown cause in the final study. These cases were grouped into the following clinically meaningful types: cleft lip with or without cleft alveolus; cleft lip and cleft palate; and cleft palate only. This review and classification process resulted in the elimination of 21.5% of the original cohort of identified cases, with most exclusions being due to suspected syndromic associations. Verbatim descriptions of the clinical findings are critical for accurate classification of diagnoses. This review process improved the precision of orofacial cleft phenotype classification for our study. Precision would have been further improved if all of the cases had verbatim descriptions of diagnoses and all medical records could have been reviewed by the classification team. © 2015 Wiley Periodicals, Inc.

    Recently tissue engineering has become available as a regenerative treatment for bone defects; however, little has been reported on the application of tissue engineering for regeneration of cleft defect tissues. Mesenchymal-derived stem cells were applied to different kinds of bone substitute and compared in different animal models, but their usage in human critical defects remained unclear. In this study we report 2 patients with unilateral alveolar cleft, treated with the composite scaffold of demineralized bone mineral and calcium sulphate (Osteoset) loaded with mesenchymal stem cells (MSCs). Computed tomograms showed 34.5% regenerated bone, extending from the cleft walls and bridging the cleft after 4 months in one case and in the other there was 25.6% presentation of bone integrity. The available data revealed the conventional bone substitute was not a suitable scaffold for the MSC-induced bone regeneration.

    The surgeon who lifts a scalpel to repair a bilateral cleft lip and nasal deformity is accountable for: 1) precise craftsmanship based on three-dimensional features and four-dimensional changes; 2) periodic assessment throughout the child's growth; and 3) technical modifications during primary closure based on knowledge gained from long-term follow-up evaluation. These children should not have to endure the stares prompted by nasolabial stigmata that result from outdated concepts and technical misadventures. The principles for repair of bilateral complete cleft lip have evolved to such a level that the child's appearance should be equivalent to, or surpass, that of a unilateral complete cleft lip. These same principles also apply to the repair of the variants of bilateral cleft lip, although strategies and execution differ slightly. PMID:19884685

    Ankyloglossia or tongue-tie is a congenital anomaly affecting the tongue, which is characterized by thick, short lingual frenulum. This condition causes many difficulties such as limited tongue protrusion, breastfeeding difficulties, speech impairment and lack of self-confidence. It is very rarely associated with any other congenital craniofacial disorders such as cleft lip, X-linked cleft palate, Van der Woude syndrome, Smith-Lemli-Opitz syndrome, Orofacial digital syndrome, Beckwith Weidman syndrome or Simpson-Golabi-Behmel syndrome. This article presents a rare case of ankyloglossia associated with cleft lip treated with diode laser in a 12-year-old Indian boy who had undergone surgical correction of associated cleft lip soon after birth. Correction of ankyloglossia at a young age would lead to enhanced phonetics, improved oral hygiene, and overall personality development.

    Cleft lip and palate take significant place in congenital malformations. We aimed to study epidemiological peculiarities of these pathologies in Georgia for 2006-2015. We compared magnitude of its distribution with the data from 1981-1990. Prevalence of cleft lip and palate in Georgia in 2006-2015 was 0.95±0.04 per 1000 live births, while in 1981-1990- it was 1.05, i.e. in contrast to 1980's frequency of these pathological conditions decreased to some extent. Distribution of cleft lip and palate varies across the country regions. The most intensive spread has been observed in Mtskheta-Mtianeti region, where prevalence composed 2.28/1000. In the rest of the regions frequency of these pathologies is significantly lower. For instance, in Kakheti the rate is equal to 1,87/1000, in Kvemo Kartli - 1.56/1000, in Shida Kartli - 1.55/1000. In the rest of the regions prevalence rate is lower than the country average. It should be noted that in Tbilisi the rate is as low as 0.80/1000. The lowest level has been reported in Guria - 0.56/1000. Currently cleft lip with palate is the most frequently occurring anomaly in Georgia accounting for 39.8% of all congenital malformations. Cleft lip alone ranks the second - 36.1%, followed by cleft palate (24.1%). These pathologies are more frequent in boys than in girls. 60.3% of the cases are reported in males, in contrast to girls - 39.7% (p<0.01). Usually, cleft palate is the most common among girls, but in our case, it had higher prevalence among boys, 53.6% vs. 46,4%. Thus cleft lip and palate distribution in Georgia is characterized by epidemiological peculiarities, which should be considered in implementation of preventive measures.

    Orthognathic surgery for the cleft lip and palate patient should be designed to achieve good facial aesthetics and a stable, functional occlusion. Maxillary and mandibular osteotomies, which benefit cleft lip and palate patients with associated dentofacial deformities, should be modified to meet the needs of the individual patient. Soft-tissue correction of the upper lip and nose adds to the overall aesthetic result, but should be performed as a separate procedure.

    The purpose of this study was to evaluate nasalance measures in German-speaking patients with different types of repaired cleft lip and palate and to find out if significant nasalance gender differences exist in the different cleft groups. A total of 125 German-speaking cleft patients (74 male and 51 female) were included in this study: 18 patients with isolated unilateral cleft lip (UCL; mean age: 13.00 +/- 2.03 years), 66 patients with complete unilateral cleft lip and palate (UCLP; mean age: 14.80 +/- 3.45 years), 25 patients with isolated cleft palate (CP; mean age: 14.60 +/- 3.48 years), and 16 patients with complete bilateral cleft lip and palate (BCLP; mean age: 14.30 +/- 3.61 years). Nasalance data were collected and computed using the NasalView hardware/software system (Fa. Tiger Electronics, Seattle, WA). Speech stimuli according to a modified Heidelberg Rhinophonia Assessment Form (sustained vowels "a," "e," "i," "o," and "u"; oral and nasal sentences; and three oral-nasal reading passages) were used to obtain nasalance scores. Nasalance distance and ratio were also calculated for the oral and nasal sentences and for one of the oral-nasal reading passages. Unpaired t tests showed no significant gender nasalance differences in each cleft group. Analysis of variance showed no significant differences in mean nasalance distance and ratio. For the nasal sentence, a significant difference (P = 0.032) in mean nasalance scores was found between the UCL and UCLP groups.

    Background: Although cleft lip and cleft palate are among the most common congenital malformations, the presence of an isolated congenital palatal fistula along with a submucous cleft is very rare. This appears as an oval-shaped, full-thickness fenestration in the palatal midline that does not fully extend anteriorly or posteriorly, accompanied by the findings of a submucous cleft. Because of the uncommon nature of this entity, there is controversy about its etiology, diagnosis, and management. Methods: Two cases of children with congenital palatal fistulae and a submucous cleft palate are presented who were treated in different settings by different surgeons. Cases are discussed along with a thorough review of the available literature. Results: Patient 1 presented at 4 years of age with “a hole in the palate” since birth and abnormal speech. His palatal fistula and submucous cleft were repaired with a modified von Langenbeck technique in Ethiopia. At a 2-year follow-up, the palate remained closed, but hypernasal speech persisted. Patient 2 was a 1-year-old presenting with failure to thrive and nasal regurgitation, who underwent a Furlow palatoplasty in the United States with good immediate results. She was unfortunately lost to follow-up. Conclusions: A congenital fenestration of the palate is rare. Reports reveal suboptimal speech at follow-up, despite various types of repair, especially when combined with a submucous cleft. Available literature suggests that repair should not focus on fistula closure only but instead on providing adequate palate length to provide good velopharyngeal function, as in any cleft palate repair.

    Usually, the nasal sequels of unilateral cleft patient are just considered as an esthetic problem to be addressed after the growth spurt of adolescence. This very narrow vision has led the cleft lip and palate treatment to a deadend. Actually, nasal sequels are the worst in terms of consequence on facial growth. 75% of complete unilateral cleft children are more oral than nasal breathers. Today, we know about the bad consequences of oral breathing on facial growth. It is not surprising to observe a high rate of small maxilla with cleft maxilla scars. In the fetus, the unilateral cleft nose deformities are well explained by the rupture of the facial envelope and the ventilatory dynamics of the amniotic fluid. Every step of the primary treatment threatens the nasal air way patency, whether when repairing lip and nose, suturing the hard palate that is the floor of the nose, or closing the alveolar cleft which controls the width of the piriform aperture. The functional and esthetic nasal sequels reflect the initial deformity, but are also the surgeon's skill and protocol choice. Before undertaking treatment, we must analyze the deformity at every level. Usually, the best option is to reopen the cleft completely to perform a combined revision of the lip, nose, and alveolar cleft after an adequate anterior maxillary expansion. If nasal breathing is necessary for an adequate facial growth, 25 years of experience showed us that it was very difficult to erase the cortical imprint of an early oral breathing pattern. So it is essential to establish a normal nasal breathing mode at the initial surgery. When the initial surgery is efficient and/or the secondary repair is successful, the final esthetic rhinoplasty, when indicated, is just performed for the sake of harmonization, with a classic internal approach and a few refinements.

    A new lever-action expansion appliance is described which is designed specifically for use in infants with cleft lip and palate. An extraoral control knob allows for easy activation, while the important anterior cleft areas are left clear for premaxillary repositioning and clinical assessment. Activation is registered by a positive clicking sound. Rapid expansion is made possible by the design of the appliance which is retained by stainless steel pins.

    Recognition that a fetus can scarlessly heal in intrauterine life led to various animal studies in the mid 1980s exploring the possibility of fetal cleft lip/palate surgery. The idea of scarless cleft repair seemed like a possible dream after the promising results from the early animal studies. In this review, we analyze the progress made in the 30 years since our first experience with animal models.

    MSX1 has been considered a strong candidate for orofacial clefting, based on mouse expression studies and knockout models, as well as association and linkage studies in humans. MSX1 mutations are also causal for hereditary tooth agenesis. We tested the hypothesis that individuals with orofacial clefting with or without tooth agenesis have MSX1 coding mutations by screening 33 individuals with cleft lip with or without cleft palate (CL/P) and 19 individuals with both orofacial clefting and tooth agenesis. Although no MSX1 coding mutations were identified, the known 101C > G variant occurred more often in subjects with both CL/P and tooth agenesis (p = 0.0008), while the *6C-T variant was found more often in CL/P subjects (p = 0.001). Coding mutations in MSX1 are not the cause of orofacial clefting with or without tooth agenesis in this study population. However, the significant association of MSX1 with both phenotypes implies that MSX1 regulatory elements may be mutated.

    As part of an international consortium, case-parent trios were collected for a genome wide association study of isolated, non-syndromic oral clefts, including cleft lip (CL), cleft palate (CP) and cleft lip and palate (CLP). Non-syndromic oral clefts have a complex and heterogeneous etiology. Risk is influenced by genes, environmental factors, and differs markedly by gender. Family based association tests (FBAT) were used on 14,486 SNPs spanning the X chromosome, stratified by type of cleft and racial group. Significant results even after multiple comparisons correction were obtained for the Duchene’s muscular dystrophy (DMD) gene, the largest single gene in the human genome, among CL/P trios (both CL and CLP combined). When stratified into groups of European and Asian ancestry, stronger signals were obtained for Asians. Although conventional sliding window haplotype analysis showed no increase in significance, analysis selected combinations of the 25 most significant SNPs in DMD identified four SNPs together that attained genome-wide significance among Asian CL/P trios, raising the possibility of interaction between distant SNPs within DMD.

    2011-07-01

    After the primary repair of cleft palate, surgeons are frequently confronted with a short soft palate and a wide velopharyngeal space, both of which are known to diminish the quality of speech. We introduce a new modification of the primary repair of cleft palate that lengthens the soft palate and helps to reduce the volume of the velopharyngeal space. Ten patients younger than 12 months with nonsyndromic cleft palate were operated on with this technique. The incision at the cleft margin extended behind the uvula as a modification to the classic design of mucoperiosteal flaps. The sagittally divided mucosal layers of each anterior tonsillar pillar are sutured at the midline 1 cm posterior to the new uvula. The rate of postoperative fistula formation and other complications were evaluated postoperatively. One patient had a uvular and partly pillar detachment at the postoperative period. All other clefts healed without complication. The primary repair of the cleft palate with the anterior pillarplasty technique is a safe and easy-to-perform procedure. This modification can effectively reduce the transverse diameter of the velopharyngeal space and increase the anteroposterior length of the palate.

    Previous studies have suggested that asymmetry for certain bilaterally represented features may be an indicator of genetic predisposition to cleft lip with or without cleft palate and may therefore be of value in the individual assessment of recurrence risk, particularly for sporadic cases. An asymmetry score has been devised that may be of use in identifying those with a high level of genetic predisposition. Stepwise logistic regression selected nine variables that together correctly classified 85% of familial cleft patients and unrelated non-cleft controls. Applying the same regression equation to sporadic cases, 26% fell into the range occupied by the majority of familial patients, suggesting that these had a high level of genetic predisposition.

    To investigate the differences in the congenital missing teeth pattern in terms of tooth type (permanent maxillary lateral incisor [MLI] and maxillary second premolar [MSP]) and sidedness (cleft vs noncleft) between boys and girls in Korean unilateral cleft lip and alveolus (UCLA) and unilateral cleft lip and palate (UCLP) patients. This study used the charts, models, radiographs, and intraoral photographs of 90 UCLA patients and 204 UCLP patients (ages 6 to 13 years). Binomial test, chi-square test, Fisher exact test, maximum likelihood analysis of variance, and the odds ratio were performed. According to the relationship between the congenital missing teeth pattern and the cleft type, the UCLP patients had 2.98 times more missing MLIs and 1.80 times more missing MSPs than did the UCLA patients. The MLI was congenitally missing more in boys than in girls, but the MSP showed the opposite tendency. Boys had a higher frequency of congenital missing MLIs and MSPs on the cleft side than did girls. However, on the noncleft side and both sides, girls had a higher frequency of congenital missing MLIs and MSPs than did boys. Results showed a gender-dominant pattern of congenital missing MLIs and MSPs. These results suggest that gender and cleft type might affect the congenital missing teeth pattern in terms of tooth type and sidedness.

    Cleft lip/palate is a critical health problem in Thailand; with an incidence rate of 2.49/1,000 live births. To insure the best outcomes, surgery should be performed near the age of three months. However; during the years 1993-2007, only 39.7% of children with a cleft lip/palate underwent an operation by the age of 3-4 months and only 58.18% by the age of 9-12 months. The purpose of the study is to determine if a cleft birth registry might facilitate timely and proper treatment for children with a cleft lip/palate. A pilot cleft birth registry, developed by the Tawanchai Cleft Center, was made available to hospitals in Khon Kaen, Roi-et, Kalasin, and Mahasarakam provinces, Thailand. Ninety-eight personnel involved in the care of children with a cleft lip/palate were recruited from the participating hospitals to evaluate the system. Assigned to one offour focus groups, participants were asked to evaluate the pilot system in terms of satisfaction and benefit. Following the focus groups, those participants that were traditionally responsible for registration were asked to use the cleft birth registry to register any newborns with a cleft lip/palate that were encountered in the course of their duties. Records were examined to determine how many newborns were properly registered and for those registered, whether proper care was received in a timely manner With 78 focus group participants responding to the satisfaction survey, results indicated mostly high levels of satisfaction with 26 (33%) participants rating satisfaction as very good, 49 (63%) as good and 3 (4%) as fair No participant rated satisfaction below fair. Furthermore, a majority stated that the cleft birth registy would benefit patients and contribute to timely treatment. During two years of active use, one hundred and thirty-seven newborns with a cleft lip/palate were registered into this cleft birth registry. Subsequent examination showed that eighty-eight percent ofregistered cases received proper

    Orofacial clefts are a group of frequently observed congenital malformations often requiring multiple hospital admissions over the lifespan of affected individuals. The aim of this study was to describe the total-population hospital admissions with principal diagnosis of cleft lip and/or palate in Australia over a 10 year period. Data for admissions to hospitals were obtained from the Australian Institute of Health and Welfare National Hospital Morbidity Database (July 2000 to June 2010). The outcome variable was a hospital separation with the principal diagnosis of cleft palate, cleft lip or cleft lip and palate (ICD-10-AM diagnosis codes Q35-Q37 respectively). Trends in rates of admission and length of stay by age, gender and cleft type were investigated. A total of 11, 618 admissions were identified; cleft palate (4,454; 0.22 per 10,000 people per year), cleft lip (2,251; 0.11) and cleft lip and palate (4,913; 0.25). Admission age ranged from birth to 79 years with males more frequently admitted. Most admissions occurred prior to adolescence in cleft palate and cleft lip and through to late teens in cleft lip and palate, declining for all groups after 25 years. This study identified population level trends in hospital separations for orofacial cleft diagnosis in Australia.

    Isolated cleft lip is the mildest form of the cleft lip and palate spectrum; however those patients are often treated with the same surgical techniques that are used for the more severe cases (advancement-rotation flaps, quadrangular flaps). Meara's cheiloplasty technique may be a less aggressive option for lip repair in isolated cleft lip or whenever the gap between labial segments is not wide. All children that had their cleft lip repaired following Meara's cheiloplasty between May 2014 and December 2015 were retrospectively reviewed. Duration of the surgical procedure, time to hospital discharge and complications were noted. Aesthetic results were evaluated in terms of lip height and symmetry, nose shape and symmetry, and scar appearance. Thirteen patients underwent Meara's cheiloplasty during this period. The average age was 6.11 months (5 to 12 months). A primary rhinoplasty was done at the same time in case of nasal asymmetry. Duration of the lip repair averaged 85 minutes. Oral feeding was started 4 hours after the procedure; bottle-feeding was withheld for 2 weeks postoperatively, as our protocol recommends after other lip repair techniques. In all 13 cases the result was a symmetrical, adequately high upper lip and a well-balanced nose, except for one case of lip scar retraction that was solved with triamcinolone infiltration. There were no other intra or postoperative complications. Meara's cheiloplasty corrects small or moderate gap cleft lip (usually cleft lip without cleft alveolus). Benefits over other teccniques are a shorter procedure and less geometric, undulate flaps that produce a harmonic lip.

    In this article, the authors describe their use of the upper triangular flap method to repair unilateral cleft lips in 250 patients with cosmetically appealing and predictable results. This method produces a straight philtral column scar that is parallel to the noncleft side and hides the surgical scars on the medial aspect of the nostril and in the lip-columellar crease. The first step is to assign the reference points along the vermilion border and the nostril sills. It is important to identify the nostril sill on the cleft nose, which could be particularly attenuated in wide clefts. Next, the upper triangular flap is designed on the upper part of the cleft side, having made allowance for the sillo-columellar distance. The dissections are performed along the drawn line joining functional points. The repair begins from the floor of the nostril, where the "neo-sill" is sutured directly opposite to the noncleft sill. The sillo-columellar distance (s-c) must be reestablished and the small triangular flap is not dissected into 3 layers to avoid devitalizing the skin. The muscle layers are identified, approximated, and held on stay sutures, which are tied in sequence. In this work, the authors identify the apparent lip length and the real lip length. It must be noted that the correction for shortening of the cleft philtral column is done on the real lip length by all other methods used for unilateral cleft lip repair, including our upper triangular flap method. On the basis of its simplicity and their postoperative results, the authors believe this approach offers further insight into cleft lip repair.

    BACKGROUND AND OBJECTIVE: Previous studies of academic achievement of children with oral clefts have mostly relied on small, clinic-based samples prone to ascertainment bias. In the first study in the United States to use a population-based sample with direct assessment, we evaluated the academic achievement of children with oral clefts relative to their classmates. METHODS: Children born with isolated oral clefts in Iowa from 1983 to 2003 were identified from the Iowa Registry for Congenital and Inherited Disorders and matched to unaffected classmates by gender, school/school district, and month and year of birth. Academic achievement was assessed by using standardized tests of academic progress developed by the Iowa Testing Programs. Iowa Testing Programs data were linked to birth certificates for all children. Regression models controlled for household demographic and socioeconomic factors. The analytical sample included 588 children with clefts contributing 3735 child-grade observations and 1874 classmates contributing 13 159 child-grade observations. RESULTS: Children with oral clefts had lower scores than their classmates across all domains and school levels, with a 5-percentile difference in the overall composite score. Children with clefts were approximately one-half grade level behind their classmates and had higher rates of academic underachievement and use of special education services by 8 percentage points. Group differences were slightly lower but remained large and significant after adjusting for many background characteristics. CONCLUSIONS: Children with oral clefts underperformed across all academic areas and grade levels compared with their classmates. The results support a model of early testing and intervention among affected children to identify and reduce academic deficits. PMID:24753523

    The binding of Co(2+) and Pb(2+) ions to the terpyridine and pyridine subunits of the ligand 1 leads to the self-complementary molecular clefts 2-6, which result from the crossover combination of orthogonal-terpyridine and linear-pyridine metal-coordination subprograms and are stabilized by strong pi-pi stacking interactions. Four different cleft-type entities, [Co(2+) (2)(1)(2)] (3), [Pb(2+) (2)(1)(2)] (4), [Co(2+) (4)(1)(2)] (5), [Pb(2+) (4)(1)(2)] (6), are generated in both solution and the solid state, and may be interconverted as a function of metal/ligand stoichiometry. One- and two-dimensional metallosupramolecular zipper architectures result from self-assembly in the solid state driven by a combination of different pi-pi stacking subprograms. The U-shaped geometry of the ligand influences the possibility of zipping and thus, in turn, the generation of different zipper architectures. The structures of 2-5 have been confirmed by X-ray crystallography; that of 6 is based on NMR spectral data.

  11. Exclusion of linkage between cleft lip with or without cleft palate and markers on chromosomes 4 and 6

    Nonsyndromic cleft lip with or without associate cleft palate (CLP) is a common craniofacial defect, occurring in {approximately}1/1,000 live births. While the defect generally occurs sporadically, multiplex families have been reported. Segregation analyses have demonstrated that, in some families, CLP is inherited as an autosomal dominant/codominant disorder with low penetrance. Several clefting loci have been proposed on multiple chromosomes, including 6p24, 4q, and 19q13.1. Association studies and linkage studies suggested a locus that mapped to 6p24. We were unable to confirm this in a linkage study of 12 multigenerational families. A subsequent linkage study by Carinci et al., however, found evidence for linkage to this region in 14 of 21 clefting families. Additionally, Davies et al. studied the chromosomes of three individuals with cleft lip and palate, all of whom had a rearrangement involving 6p24. Their investigation supported a locus at 6p24. Carinci et al. reported that the most likely position for a clefting locus was at D6S89, which is centromeric to EDN1. This is in contrast to the findings of Davies et al., who suggested a placement telomeric to EDN1. F13A, which had been implicated in the initial association studies, is telomeric to EDN1. Thus, the region between F13A and D6S89 encompasses the regions proposed by both Davies et al. and Carinci et al. A second clefting locus, at 4q, was proposed by Beiraghi et al., who studied a single multigenerational family by linkage analysis. Their data suggested a locus near D4S175 and D4S192. 10 refs., 1 tab.

    The latitudinal motion of the cleft (the polar cusp) associated with the southward interplanetary magnetic field (IMF) and substorm activity is examined. The cleft location is identified on the basis of the location of midday auroras and of electron precipitation by the OGO 4 and ISIS 1 satellites. It is found that the IMF and substorm activity control independently the latitude of the cleft and that they can shift the cleft location by 3 or 4 deg under average conditions.

    To determine factors associated with orofacial clefts and postsurgical complications of cleft lip and palate repair surgeries in northwestern Tanzania. This was a cohort study involving patients with orofacial clefts. Associated factors (family history of orofacial clefts, maternal use of alcohol and cigarette smoking during pregnancy) were obtained through interviews with accompanying parents. Antenatal cards were used to obtain maternal age at birth and birth weight. Ninety-four patients with different orofacial clefts were seen. Among them, 46.8% (44/94), 13.8% (13/94), and 39.4% (37/94) had cleft lip, cleft palate, and cleft lip and palate, respectively. About 15% of orofacial cleft cases had a positive family history of orofacial clefts. Among these, 7.4% had an affected relative on the maternal side, 4.3% had an affected relative on the paternal side, and 3.2% had an affected sibling. This difference was statistically significant (chi-square  =  27.7, p < .001). Orofacial cleft was significantly associated with order of birth (chi-square  =  21.0, p < .001). Postoperative complications observed included palatal fistula and philtrum dehiscence. Family history of orofacial clefts and order of birth were significantly associated with orofacial clefts in northwestern Tanzania. These factors have been associated with risk of orofacial clefts elsewhere and suggest a hereditary role in the etiology of orofacial cleft. Palatal fistula and philtrum dehiscence were postsurgical complications observed in orofacial clefts patients who had primary surgery past the recommended age. These complications could have resulted from delayed surgery and absence of presurgical procedures.

    To describe a series of children diagnosed with type I congenital laryngeal clefts (LC-I) and treated, due to various presentations, with endoscopic injection augmentation (IA). Case series with chart review. Tertiary care academic children's hospital in Edmonton, Canada. All pediatric patients diagnosed with LC-I and treated with IA in a single tertiary care practice. The children were identified from a prospectively collected database. Only those who were treated with IA and had a minimum follow-up of 3 months were included. The authors collected demographics, diagnoses, surgical procedures, number of IA procedures, clinical outcomes, and complications. Over a period of 8 years, 43 patients were diagnosed with LC-I. Eighteen had undergone IA over the past 4 years. Mean age at IA was 37.11 ± 32.68 months with a male-to-female ratio of 1.25:1. The indications were swallowing dysfunction (13), atypical croup (2), chronic cough (1), cyanotic spells (1), and asthma (1). Seven patients required repeated injections (mean, 2.57 injections). A total of 13 patients responded with resolution of symptoms in question. A single postoperative complication was recorded. IA is a brief, simple management option that succeeds in a number of children with LC-I. It is minimally morbid and supplements other conservative approaches to treat the condition.

  15. Aerodynamic studies of cleft-palate speech.

    1978-05-01

    The aerodynamic oral-nasal factors related to the speech of two groups of cleft-palate children were evaluated. One group presented hypernasality and the other group presented normal nasal resonance. The aerodynamic parameters evaluated were oral pressure, nasal flow, and flow-pressure ratio (nasal flow/oral pressure). Oral temperature readings were also obtained. These parameters were evaluated under three conditions (1) blowing, (2) vocalizing the vowel /i/, and (3) reading eight sentences representing two different rhythm patterns, two types of consonant loadings, and two conditions of syllable stress. The findings revealed significant differences between the hypernasal and normal resonance groups in flow-pressure ratio, oral pressure, and nasal flow while subjects were reading sentences. However, only a small proportion of the variability in these aerodynamic measurements could be accounted for based on the classification of hypernasality or normal nasal resonance. Oral-nasal aerodynamic studies done during speaking activity are more useful clinically than blowing activity or saying vowel sounds. No aerodynamic differences were noted between the two groups for the different rhythm and stress patterns and phonemic loadings within the sentences used.

    Treatment of oronasal fistulae in cleft patients remains a surgical challenge because of its high failure rate. The authors report the results of an aggressive surgical technique using the total elevation of palatal mucoperiosteum, even for small fistulae. This approach was used on twelve consecutive patients, from five to 33 years of age, presenting with a Pittsburgh classification type IV palatal fistulae. The surgical procedure was total elevation of the hard palate mucoperiosteum starting from the dental sulcus combined with sealed double layer sutures. Clinical and photographical control was made at least 6 months after to detect a possible relapse. The success rate was 100%. No relapsing fistula was observed with follow-up ranging from 6 to 36 months. This technique allows wide exposure and safe closure of the nasal layer. It is simple and leaves no raw bone surface exposed and no additional scar. The authors think it can be used in all type IV fistulae less than 1cm wide. Several other surgical techniques have been described to close palatal fistulae: local turnover flaps, pedicled flaps from adjacent oral tissue, tongue flaps, tissue expansion, and even free flaps. Obturator prostheses have also been used. The technique we report, even if more aggressive, seems to be more reliable with fewer relapse and sequelae. Copyright © 2011 Elsevier Masson SAS.

    The purpose of the study was to report the types and patterns of cleft lip with/without cleft alveolus and palate as well as cleft palate only as seen in Aden, Yemen. Retrospective, centre-based study conducted at the Cleft Lip and Palate Centre, Aden University, Yemen. Statistical evaluation of the data from all cleft patients who were registered at or referred to this centre during the years 2005-2011. A total of 1110 cleft patients were seen during the period studied (2005-2011). Amongst these there were 183 (16.48%) with a cleft lip and 144 (12.98) with a cleft of lip and alveolus, 228 (20.54%) had a cleft palate, and 555 (50%) had a combination of cleft lip, alveolus, and palate. The clefts were found more often in males than in females (56.5% boys versus 43.5% girls). This difference was statistically significant (p ≤ 0.001). Statistically significant sex differences were also noted when evaluating the various cleft types. Isolated cleft palates were found most often in females. Among the cleft palate cases there were 102 (9.2%) with a cleft soft palate only. The ages of the patients were between one day and 40 years. Two hundred and one children (18%) had a positive family history of clefts. Among the risk factors considered in this study, consanguineous marriages among cousins were found most frequently (in 48% of the cases). In contrast to this, only 10% of the mothers had reported to have been taking medication directly prior to or during the first trimester of their pregnancy. On average the mothers were neither very young nor very old. The prevalence rate of orofacial cleft types among this Yemeni sample was similar to prevalence rates previously reported in white Caucasians. The present study did neither find many cases with medication before, nor during, pregnancy; there were few young or very old mothers; and the incidence of positive family histories was similar to those found in other studies on clefts. However, consanguineous marriages were

    Cleft lip and/or palate (CL/P) represent the most common congenital anomalies of the face. To assess the relationship between maternal smoking, gender and CL/P. This is an epidemiological cross-sectional study. We interviewed 1519 mothers divided into two groups: mothers of children with CL/P (n=843) and mothers of children without CL/P (n=676). All mothers were classified as smoker or non-smoker subjects during the first trimester of pregnancy. To determine an association among maternal smoking, gender, and CL/P, odds ratios were calculated and the adjustment was made by a logistic regression model. An association between maternal smoking and the presence of cleft was observed. There was also a strong association between male gender and the presence of cleft (OR=3.51; 95% CI 2.83-4.37). By binary logistic regression analysis, it was demonstrated that both variables were independently associated with clefts. In a multivariate analysis, male gender and maternal smoking had a 2.5- and a 1.5-time greater chance of having a cleft, respectively. Our findings are consistent with a positive association between maternal smoking during pregnancy and CL/P in male gender. The results support the importance of smoking prevention and introduction of cessation programs among women with childbearing potential.

    Orofacial clefts are thought to be determined by the interplay of genetic and environmental factors. Experiments on animals demonstrated that vitamin B12 supplemented diets antagonize selected teratogens during palatogenesis. Increased propionylcarnitine in neonates is regarded as a marker of maternal vitamin B12 deficiency. The retrospective study was undertaken to determine whether increased propionylcarnitine in newborns is associated with orofacial clefts. Fifty-two newborns with isolated cleft lip with or without cleft palate (CLP) and 107 control newborns without congenital anomalies were investigated. Whole blood propionylcarnitine concentrations were measured using tandem mass spectrometry. The mean concentrations of propionylcarnitine in newborns with clefts and controls were 2.82±1.06µmolL(-1) and 2.68±0.94µmolL(-1), respectively. T-test for equality of means did not confirm any significant differences between both groups (P=0.381). Deficiency of vitamin B12 with metabolic disturbances seems not to be a risk factor for CLP in the investigated group of patients. © 2010 Blackwell Publishing Ltd.

    Pilonidal disease is a common condition affecting young patients. It is often disruptive to their lifestyle due to recurrent abscesses or chronic wound drainage. The most common surgical treatment, "cystectomy," removes useful tissue unnecessarily and does not address the etiology of the condition. Herein, we describe the etiology of pilonidal disease and our technique for definitive management of pilonidal disease using the cleft lift procedure. In this paper, we present our method of performing the cleft lift procedure for pilonidal disease including perioperative management and surgical technique. We have used the cleft lift procedure in nearly 200 patients with pilonidal disease, in both primary and salvage procedures settings. It has been equally successful in both settings with a high rate of success. It results in a closed wound with relatively minimal discomfort and straightforward wound care. We have described our current approach to recurrent and complex pilonidal disease using the cleft lift procedure. Once learned, the cleft lift procedure is a straightforward and highly successful solution to a chronic and challenging condition.

    Patients with cleft lip and/or palate go through a lifelong journey of multidisciplinary care, starting from before birth and extending until adulthood. Presurgical orthopedic (PSO) treatment is one of the earliest stages of this care plan. In this paper we provide a review of the PSO treatment. This review should help general and specialist dentists to better understand the cleft patient care path and to be able to answer patient queries more efficiently. The objectives of this paper were to review the basic principles of PSO treatment, the various types of techniques used in this therapy, and the protocol followed, and to critically evaluate the advantages and disadvantages of some of these techniques. In conclusion, we believe that PSO treatment, specifically nasoalveolar molding, does help to approximate the segments of the cleft maxilla and does reduce the intersegment space in readiness for the surgical closure of cleft sites. However, what we remain unable to prove equivocally at this point is whether the reduction in the dimensions of the cleft presurgically and the manipulation of the nasal complex benefit our patients in the long term.

    To investigate a possible correlation between fistula and dental decay in children at 5 years of age from a single-surgeon series of cleft palate repairs. Retrospective review of data over a 9-year period between 2003 and 2011 of cleft palate repairs performed by the senior author at Birmingham Children's Hospital, U.K. Data collected on age, sex, age at repair, presence of fistula, and number of decayed, missing, or filled primary teeth (i.e., decayed, missing, and filled teeth score) at age 5 years. The overall fistula rate for this patient population was 24.1%. Fistulae were more common in the more severe forms of cleft type, as was frequency of dental decay. Comparison of fistula versus nonfistula groups showed a higher rate of dental decay (40%) in the fistula group, compared with only 20% in the nonfistula group (P = .036). A positive association was established between dental decay and the presence of a fistula. Although not proven as causative, possible reasons for this include nasal mucus retaining sugary food in the mouth and an overall prolonged food-clearance time. The known association between severity of cleft and an increased likelihood of a fistula and severity of cleft and increased dental decay were again demonstrated but were not found to be the exclusive explanation for the new finding of an association between fistulae and higher dental decay rates.

    Orientals are at higher risk for cleft lip with our without cleft palate (CL[+-] P) than Caucasians or blacks. The authors collected demographic and family data to study factors contributing to the etiology of CL[+-]P in Shanghai. The birth incidence of nonsyndromic CL[+-]P (SHanghai 1980-87) was 1.11/1,000, with a male/female ratio of 1.42. Almost 2,000 nonsyndromic CL[+-]P probands were ascertained from individuals operated on during the years 1956-83 at surgical hospitals in Shanghai. Detailed family histories and medical examinations were obtained for the probands and all available family members. Genetic analysis of the probands' families were performed under the mixed model with major locus (ML) and multifactorial (MFT) components. The hypothesis of no familial transmission and of MFT alone could be rejected. Of the ML models, the autosomal recessive was significantly most likely and was assumed for testing three complex hypothesis: (1) ML and sporadics; (2) ML and MFT; (3) ML, MFT, and sporadics. None of the complex models were more likely than the ML alone model. In conclusion, the best-fitting, most parsimonious model for CL[+-]P in Shanghai was that of an autosomal recessive major locus. 37 refs., 1 tab.

    Cleft size at the time of palate repair might affect the difficulty of surgical repair and, thus, indirectly postoperative maxillary growth. This retrospective study aimed to determine whether a correlation existed between the cleft size at the time of palate repair and the growth of the maxilla. Maxillary dental casts of 39 infants with non-syndromic complete unilateral cleft lip and palate, taken at the time of palate repair, were used to measure cleft size. Cleft size was defined as the percentage of the total palatal area. The later growth of the maxilla was determined using lateral and postero-anterior cephalometric radiographs taken at 9 years of age. The Pearson correlation analysis was used for statistical analysis. The results showed negative correlations between cleft size and the maxillary length (PMP-ANS, PMP-A) and the maxillary protrusion (S-N-ANS, SNA). These data suggest that in patients with complete unilateral cleft lip and palate there is a significant correlation between the cleft size at the time of palate repair and the maxillary length and protrusion. Patients with a large cleft at the time of palate repair have a shorter and more retrusive maxilla than those with a small cleft by the age of 9 years.

    The objectives of this study were to compare the ratings of professionals and laypeople with and without a cleft regarding the facial aesthetics of adult patients previously treated for orofacial clefting. The necessity for further treatment, as perceived by the respective groups, is also compared. The design of the study was a cross-sectional study. Professionals (two plastic surgeons, one dentist, one orthodontist, and one psychologist) and laypeople (one male and one female adult without a cleft and one male and one female adult with a cleft) were recruited to rate photographs of 80 non-syndromic cleft patients treated by the Australian Craniofacial Unit from 1975 to 2009. Facial aesthetics were measured by a visual analogue scale (VAS; 0-100 mm). High values indicated good aesthetics. Necessity for further treatment was also measured by a VAS (0-100 mm). High values indicated high perceived need for further treatment. The professionals rated facial aesthetics significantly lower and had a lower perception of need for further treatment than the raters with and without a cleft. The laypeople with a cleft rated facial aesthetics significantly higher and had a lower perceived need for further treatment than laypeople without a cleft. The non-surgical professionals rated facial aesthetics significantly lower and had a lower perceived need for further treatment than the surgical professionals. Differences exist in the facial aesthetics ratings and perceived need for further surgery between professionals and laypeople with and without a cleft. This should be considered when managing cleft treatment expectations.

    The noses of patients with clefts are often functionally inadequate. The aim of the present study was to evaluate the correlation between size of the maxillary cleft in infancy and size and function of the nasal airway in adults with unilateral cleft lip and palate (UCLP). This is a long-term follow up study including 53 patients with UCLP born between 1960 and 1987 and treated at the Cleft Lip and Palate Centre, Uppsala University Hospital, Sweden. Lip repair was performed at 3-4 months of age followed by either a one-stage or a two-stage palatal closure. The size of the cleft was measured on infant maxillary dental casts. Nasal minimum cross-sectional area (cm(2)) and volume (cm(3)) (acoustic rhinometry), air flow resistance (Pa s/cm(3)) (rhinomanometry), peak inspiratory flow (l/min) (peak nasal inspiratory flow) and number of identified odours (Scandinavian odor-identification test) were assessed in adulthood. The size of the maxillary cleft varied considerably at infancy. The size of the nasal airway and its function on the cleft side in adulthood were reduced compared with the non-cleft side, but no correlations were found between size of the initial cleft in infancy and size and function of the nasal airway in adulthood. In adults born with UCLP, therefore, size of the maxillary cleft in infancy does not seem to affect size and function of the nasal airway in adulthood.

    Objective : This exploratory research sought to extend the cleft phenotype by identifying movement-related soft tissue appearance changes in the midfacial region in individuals with cleft lip/palate or those with genetic susceptibility to cleft lip/palate (unaffected relatives). The cleft phenotype (clinically identified orofacial cleft or subclinical orbicularis oris defect) was hypothesized to be associated with movement related appearance changes in the midfacial region, e.g., with furrowing and dimpling during speech. Design : Changes in the appearance of skin in the midfacial region, including a newly identified phenotypic feature, nasolabial fold (NLF) discontinuity, were described and compared across groups. Participants : Individuals with cleft lip (n  =  42), unaffected relatives of persons with a cleft (n  =  57) and healthy controls (n  =  41) were compared. Results : Frequencies of NLF discontinuity differed across cleft, relative, and control groups. NLF discontinuities were observed more frequently in individuals with a cleft phenotype (overt cleft or previously identified orbicularis oris muscle defect) than in those with no underlying muscular defect (Fisher exact test, P  =  .014). Conclusion : Results suggest that the appearance of facial soft tissue during movement of the midface is moderated at least in part by underlying cleft risk factors, indicating certain facial movements as candidate physical markers for extension of the cleft phenotype.

    To investigate the association between non-syndromic cleft lip with or without cleft palate (NSCL/P) and environmental factors in Ningxia population. This case-control study involved 453 NSCL/P patients and 452 normal newborns from Ningxia. A questionnaire focusing on various factors, including family history, pregnancy reaction, drug use during pregnancy, and infections, was used and responses were analyzed through Chi-square test and Logistic regression analysis with SPSS 16.0. The constituent ratio of different types of NSCL/P was cleft lip∶cleft lip and palate∶cleft palate equal to 1︰2.02︰1.51. Logistic regression analysis revealed that abnormal pregnancy, infection, abortion, drugs, drinking, smoking, and living near factories likely increased the risk of NSCL/P (P<0.05). Single fetus, pregnancy-related nausea, vomiting, parents' moderate tastes, and eating soy foods and fruits decreased the risk of NSCL/P (P<0.05). The incidence of NSCL/P should be reduced to enhance the conditions of women during pregnancy by maintaining a balanced diet and avoiding infections, abortion, drugs, and negative habits.

    The aim of this study was to assess speech outcomes and dental arch relationship of 5-year-old Czech patients with unilateral cleft lip and palate (UCLP) who have undergone neonatal cleft lip repair and one-stage palatal closure. Twenty-three patients with UCLP, born between 2009 and 2010, were included in the study. Three universal speech parameters (hypernasality, articulation and speech intelligibility) have been devised for speech recordings evaluation. Outcomes of dental arch relationship were evaluated by applying the GOSLON Yardstick and subsequently compared with the GOSLON outcome of other cleft centers. Moderate hypernasality was present in most cases, the mean value for articulation and speech intelligibility was 2.07 and 1.93, respectively. The Kappa values for inter-examiner agreement for all the three speech outcomes ranged from 0.786 to 0.808. Sixty-three percent of patients were scored GOSLON 1 and 2, 26% GOSLON 3, and 10% GOSLON 4. GOSLON mean score was 2.35. Interrater agreement was very good, represented by kappa value of 0.867. The treatment protocol, involving neonatal cleft lip repair and one-stage palatal repair performed up to the first year of UCLP patient's life, has shown good speech outcomes and produced very good treatment results in regard to maxillary growth, comparable with other cleft centers.

    Octyl-2-cyanoacrylate (Dermabond; Ethicon, Somerville, NJ) is a synthetic tissue adhesive recently approved for skin closure. This study was designed to assess its effectiveness for use in clefts lip repairs. Sixty-four patients with unilateral, bilateral, or midline cleft lip defects were repaired. The ages at repair ranged from 4 days to 19 months, with an average of 46.5 days. Follow-up ranged from 6 months to 3 years. No complications were found. Several advantages were observed: shorter operative time, formation of a protective barrier, simplified incision care, no need for suture removal, and improved scar outcome. This study supports octyl-2-cyanoacrylate as an alternative to skin sutures in primary cleft lip repair.

    Cleft lip and palate (CLP) is a craniofacial malformation affecting more than seven million people worldwide that results in defects of the hard palate, teeth, maxilla, nasal spine and floor, and maxillodental asymmetry. CLP facial soft-tissue depth (FSTD) values have never been published. The purpose of this research is to report CLP FSTD values and compare them to previously published FSTD values for normal children. Thirty-eight FSTDs were measured on cone beam computed tomography images of CLP children (n = 86; 7-17 years). MANOVA and ANOVA tests determined whether cleft type, age, sex, and bone graft surgical status affect tissue depths. Both cleft type (unilateral/bilateral) and age influence FSTDs. CLP FSTDs exhibit patterns of variation that differ from normal children, particularly around the oronasal regions of the face. These differences should be taken into account when facial reconstructions of children with CLP are created.

  15. Ethics in Numbers: Auditing Cleft Treatment in Mexico and Beyond.

    Taylor-Alexander, Samuel

    2017-09-01

    Plastic surgeons around the globe are implementing projects that mix audit with medical research to ensure and improve the level of care offered to patients with cleft lip and palate. Drawing on recent literature on "audit culture" and the global growth of "performance indicators" as a form of governance, I demonstrate the conjugation of ethics and the production of numerical indicators in cleft treatment. By standardizing documentation, cleft treatment audit programs facilitate evidence-based medicine and a form of reflexive self-governance. However, the abstraction that accompanies standardization is amplified as corollary data practices travel. In emerging as the answer to improving treatment, these projects lock out the politico-economic factors that mediate medical care in resource poor settings. This danger is compounded by the tendency of numerical governance to replace political conversation with technocratic expertise. © 2016 by the American Anthropological Association.

  16. Density trends of negative ions at Titan

    The Electron Spectrometer part of the Cassini Plasma Spectrometer (CAPS-ELS) has revealed the existence of negative ions in Titan's ionosphere (Coates et al, 2007, Waite et al, 2007). These are observed during every encounter when the instrument points in the ram direction at altitudes between 950 and 1400 km. The heaviest ions observed so far have masses up to 13 800 amu/q. This suggests that complex hydrocarbon and nitrile chemical processes take place in Titan's upper atmosphere, probably playing a role in haze formation. Even heavier particles such as tholins can form which fall to lower altitudes and build up on Titan's surface (Coates et al., 2009). Coates et al. (2009) discussed trends in the highest masses observed with solar zenith angle (SZA), altitude and latitude. We are extending this study to density trends of different masses. With data from over 34 encounters and taking advantage of an increase in the duty cycle of measurements during recent flybys we have accumulated a large negative ion database. Groups of masses can be identified because recurrent peaks are observed in the mass-per-charge spectra of different encounters. We have updated these mass groups according to the spectra including the most recent flybys. This includes a heavy group of 625 amu/q and above. We investigate the effects of different controlling parameters such as altitude, solar zenith angle, latitude and possible seasonal effects. The aim of this study is to help constrain the chemical formation and destruction processes of negative ions in Titan's ionosphere. By studying SZA trends we can for example learn about whether nightside reactions or photochemical reactions yield higher densities for the different groups. We present the results and discuss their implications. For instance, the heaviest mass group (>625 amu/q) negative ions are only present at altitudes below 1100 km. Densities of this mass group are highest on the nightside however there are some moderate densities

    To characterize Eustachian tube function using the forced response test in young children with cleft palate with or without cleft lip after palatoplasty with tympanostomy tubes inserted prepalatoplasty and compare these results with those of a 1986 study that evaluated a similar population using identical methods. Outpatient research clinic. A total of 34 children with cleft palate were tested at an average age of 18.6 ± 4.0 months. MAIN OUTCOME MEASUREs: Passive and active measures for the forced response test. Of the sample, 13 ears could not be tested, and tests on 24 ears were incomplete. The forced response test showed that the passive Eustachian tube function parameters were similar to those of normal adults and children. The percentage of ears that showed tubal dilation with swallowing was 60%. The active resistance and dilatory efficiency were similar to those of a normal adult population. A 1986 study of Eustachian tube function in postpalatoplasty subjects with cleft palate (37 ears) aged 15 to 26 months documented Eustachian tube dilation with swallowing in 84% of the ears. In the present study, which focused on a similar population, the frequency of tubal dilation was 60%. Nonetheless, both frequencies are significantly greater than the dilation frequency of 27% reported for 56 ears of subjects with cleft palate tested between 3 months and 18 years with tympanostomy tubes inserted for persistent otitis media with effusion. This suggests that dilation during the forced response test may be a prognostic marker for those children with cleft palate who will resolve their ear disease at an early age.

  18. Dislocated Tongue Muscle Attachment and Cleft Palate Formation.

    In Pierre Robin sequence, a retracted tongue due to micrognathia is thought to physically obstruct palatal shelf elevation and thereby cause cleft palate. However, micrognathia is not always associated with palatal clefting. Here, by using the Bmp7-null mouse model presenting with cleft palate and severe micrognathia, we provide the first causative mechanism linking the two. In wild-type embryos, the genioglossus muscle, which mediates tongue protrusion, originates from the rostral process of Meckel's cartilage and later from the mandibular symphysis, with 2 tendons positive for Scleraxis messenger RNA. In E13.5 Bmp7-null embryos, a rostral process failed to form, and a mandibular symphysis was absent at E17.5. Consequently, the genioglossus muscle fibers were diverted toward the lingual surface of Meckel's cartilage and mandibles, where they attached in an aponeurosis that ectopically expressed Scleraxis. The deflection of genioglossus fibers from the anterior-posterior toward the medial-lateral axis alters their direction of contraction and necessarily compromises tongue protrusion. Since this muscle abnormality precedes palatal shelf elevation, it is likely to contribute to clefting. In contrast, embryos with a cranial mesenchyme-specific deletion of Bmp7 (Bmp7:Wnt1-Cre) exhibited some degree of micrognathia but no cleft palate. In these embryos, a rostral process was present, indicating that mesenchyme-derived Bmp7 is dispensable for its formation. Moreover, the genioglossus appeared normal in Bmp7:Wnt1-Cre embryos, further supporting a role of aberrant tongue muscle attachment in palatal clefting. We thus propose that in Pierre Robin sequence, palatal shelf elevation is not impaired simply by physical obstruction by the tongue but by a specific developmental defect that leads to functional changes in tongue movements. © International & American Associations for Dental Research 2015.

    Optimal timing for cleft lip rhinoplasty is controversial. Definitive rhinoplasty is deferred until facial skeletal growth is completed. Intermediate rhinoplasty is performed after stabilization of the grafted alveolar bone, because the grafted bone tends to be absorbed over several months postoperatively, distorting the nasal profile. Here, we report our experience with simultaneous rhinoplasty during alveolar bone grafting for indicated patients, describe our surgical technique that ensures long-term bone graft survival, and report graft take rates and nasal profile changes. This retrospective chart review included a total of 54 patients; 44 underwent alveolar bone grafting only, and 10 underwent simultaneous cleft lip rhinoplasty. All surgeries were conducted with a judicious mucosal incision for tensionless wound closure. Bone graft take was evaluated with dental radiographs by the Bergland classification. Further, nasal aesthetic outcome was evaluated with medical photographs, based on nostril height and width and alar base width. In total, 96.3% of clefts showed graft success with Type I (66.7%) or Type II (27.8%) classifications; only 3.7% of clefts showed unfavorable results classified as Type III, and no clefts showed Type IV failure. The nasal shape was flatter with a decreased nostril height and increased nostril width after alveolar bone grafting, while nostril height was increased and nostril width was decreased in patients who underwent simultaneous rhinoplasty. With surgical techniques ensuring alveolar bone graft survival, simultaneous cleft lip rhinoplasty can result in nasal aesthetic improvement for patients with severe nasal deformities, decreasing the number of operations.

    Cloverleaf skull syndrome, or Kleeblattschädel syndrome, is a rare malformation in which the skull has a cloverleaf appearance. It is caused by the premature closure of several sutures, being evident before birth. To present our experience in a case of cloverleaf skull syndrome, and update the information from the literature. A female infant of 5 months of age, diagnosed at birth with cleft lip and palate and hydrocephaly. A peritoneal ventricle valve was implanted at 30 days of life, and an ocular enucleation was performed due to an infectious process. The patient was followed-up in Genetics, where it confirmed a macrocephaly and craniosynostosis type cloverleaf skull. The 46XX cytogenetic study and echocardiography were normal. The brain CT scan showed multiple anomalies associated with hydrocephaly and non-specific malformations. Cloverleaf skull may be present in isolated form or associated with other congenital abnormalities, leading to various craniosynostosis syndromes, such as Crouzon, Pfeiffer or Carpenter. It may also be a component of the amniotic rupture sequence or to different dysplasias, such as campomelic dysplasia, thanatophoric dysplasia type 2, or the asphyxiating thoracic dystrophy of Jeune. The case presented does not fulfil all the characteristics needed to be included within a specific syndrome, and on not having a family history that suggests a hereditary pattern or chromosome abnormalities, it is concluded that it is a case of a congenital anomaly of sporadic presentation.

    Abstract Background: Rathke cleft cyst (RCC) is a rare cystic sellar entity, which is usually small in size and asymptomatic in most patients. RCC presenting panhypopituitarism and a cystic lesion with rim enhancement on magnetic resonance imaging is extremely rare. Therefore, it is easy to be misdiagnosed as pituitary abscess because of the similar clinical manifestations and neuroimaging changes. Case summary: We report a rare case of RCC masquerading as pituitary abscess clinically and radiologically with no evidence of central nervous system infection. The patient was initially suspected to be diagnosed with pituitary abscess, which was denied by the histopathological findings of RCC with no intraoperative drainage of abscess. We present an uncommon case of RCC masquerading as pituitary abscess in a 62-year-old Chinese male patient. The patient was admitted to Peking Union Medical College Hospital complaining of severe frontal pulsatile headache, visual acuity deficit, polyuria, polydipsia, and slight disturbance of consciousness. The biochemical and endocrinological examinations revealed severe hyponatremia and panhypopituitarism. Magnetic resonance imaging showed a sellar lesion with the apparent cystic change and rim enhancement. Accordingly, pituitary abscess was misdiagnosed at the beginning. The patient received hormone replacement therapy and underwent a trans-sphenoidal surgery. The surgical findings were uneventful. The histopathological examinations showed no infiltration of inflammatory cells or pus, and proved the lesion to be RCC. Conclusion: Through this rare case, we aim to emphasize that the differential diagnosis of sellar lesions requires constant vigilance and that RCC may lead to clinical and radiological changes similar with pituitary abscess.

    The Present article describes in short etiology of cleft lip and cleft palate. With this in-born defect, patient develops crucial problems with feeding, phonation, overall growth and development of affected and allied soft and hard tissue structures. This in turn results in deformity and asymmetry which is going to affect functional requirements as well as aesthetic outlook. Hence it really becomes mandatory to correct this defect surgically as early as possible, at stipulated timings so as to avoid present and future anticipated problems.

    Oro-facial clefts are one of the most common birth defects and may be associated with other genetic anomalies. Aggressive periodontitis is a rare condition that progresses rapidly, but affects only a small percentage of the population. Most of the cases of aggressive periodontitis are familial. Even though, literature has documented the association of various genetic disorders with aggressive periodontitis, the aggressive periodontitis in patients with isolated cleft lip (CL) have never been addressed. Here, we report a rare case of isolated CL with generalized aggressive periodontitis. The concomitant presentation of isolated CL with aggressive periodontitis in an individual has clinical significance for multi-disciplinary care. PMID:25810600

    Management of cleft lip and palate requires a unique understanding of the various dimensions of care to optimize outcomes of surgery. The breadth of treatment spans multiple disciplines and the length of treatment spans infancy to adulthood. Although the focus of reconstruction is on form and function, changes occur with growth and development. This review focuses on the surgical management of the primary cleft lip and nasal deformity. In addition to surgical treatment, the anatomy, clinical spectrum, preoperative care, and postoperative care are discussed. Principles of surgery are emphasized and controversies are highlighted.

    Truncating mutations were found in the PHF8 gene (encoding the PHD finger protein 8) in two unrelated families with X linked mental retardation (XLMR) associated with cleft lip/palate (MIM 300263). Expression studies showed that this gene is ubiquitously transcribed, with strong expression of the mouse orthologue Phf8 in embryonic and adult brain structures. The coded PHF8 protein harbours two functional domains, a PHD finger and a JmjC (Jumonji-like C terminus) domain, implicating it in transcriptional regulation and chromatin remodelling. The association of XLMR and cleft lip/palate in these patients with mutations in PHF8 suggests an important function of PHF8 in midline formation and in the development of cognitive abilities, and links this gene to XLMR associated with cleft lip/palate. Further studies will explore the specific mechanisms whereby PHF8 alterations lead to mental retardation and midline defects. PMID:16199551

    Although no universal consensus exists on treatment of cleft palates, early hard palate closure is commonly performed. The aim of the present study was to determine the influence of a vomer flap for early hard palate closure on residual palatal cleft width in patients with a unilateral complete cleft lip and palate (UCLP). Forty-seven UCLP patients were retrospectively divided into two groups. Group A consisted of 25 patients who underwent early lip closure and simultaneous hard palate closure using a vomer flap. Group B included 22 patients who had lip closure only at first surgery. Palatal cleft widths of both groups were measured at two time points and were compared using the Mann-Whitney U test to examine the influence of vomerplasty in this very early stage. No significant difference of baseline characteristics between the groups was found, and comparison of age at the time of surgeries was not significantly different. Mean age at the time of vomerplasty was 4.0 months. After the first surgery, a significantly greater total cleft width reduction of 5.0 mm average was found in group A compared to only 1.5 mm reduction in group B. This reduction took place after an average of 7.1 and 7.0 months, respectively. Lip closure accompanied by early hard palate closure using a vomer flap is associated with a significant postoperative reduction of the residual cleft when compared to lip closure only. This study shows another great advantage of performing early hard palate closure using a vomer flap.

    Cleft lip and palate (CLP) is often a distressful abnormality for both mother and child. In our setting, CLP is generally associated with witchcraft or ancestral spirits. The mother is often accused of infidelity during pregnancy. We wanted to determine the feelings of parents and the wider public towards CLP babies, to establish what parents believed were the causes of CLP and to establish the postpartum marital status. One hundred and twenty-four parents were prospectively included in the study. They were interviewed using a structured questionnaire. One hundred and fifteen mothers and four fathers said they loved their babies. Thirty-eight parents attributed CLP to witchcraft. Nineteen percent of the mothers were divorced. The responses to our questionnaire show that although CLP babies are loved by their parents, the condition is associated with stigma and superstition.

    We have recently presented the Old Spanish Pointer dog, with a 15-20% spontaneous congenital cleft palate rate, as a unique experimental model of this disease. This study aimed to describe the cleft palate of these dogs for surgical research purposes and to determine whether congenital cleft palate influences maxillofacial growth. Seven newborn Old Spanish Pointer dogs of both sexes, comprising a cleft palate group (n = 4) and a normal palate group (n = 3), were fed using the same technique. Macroscopic photographs and plaster casts from the palate, lateral radiographs and computer tomograms of the skull were taken sequentially over 41 weeks, starting at week 5. The cleft morphology, the size and the tissue characteristics in these dogs resembled the human cleft better than current available animal models. During growth, the cleft width varies. Most of the transverse and longitudinal measures of the palate were statistically lower in the cleft palate group. The cleft palate group showed hypoplasia of the naso-maxillary complex. This model of congenital cleft palate seems suitable for surgical research purposes. A reduced maxillofacial pre- and post-natal development is associated to the congenital cleft palate in the Old Spanish Pointer dog.

    Recent advances in prenatal imaging have made possible the in utero diagnosis of cleft lip and palate and associated deformities. Postnatal diagnosis of cleft lip is made clinically, but imaging still plays a role in detection of associated abnormalities, surgical treatment planning, and screening for or surveillance of secondary deformities. This article describes the clinical entities of cleft lip with or without cleft palate (CLP) and isolated cleft palate and documents their prenatal and postnatal appearances at radiography, ultrasonography (US), magnetic resonance (MR) imaging, and computed tomography (CT). Imaging protocols and findings for prenatal screening, detection of associated anomalies, and evaluation of secondary deformities throughout life are described and illustrated. CLP and isolated cleft palate are distinct entities with shared radiologic appearances. Prenatal US and MR imaging can depict clefting of the lip or palate and associated anomalies. While two- and three-dimensional US often can depict cleft lip, visualization of cleft palate is more difficult, and repeat US or fetal MR imaging should be performed if cleft palate is suspected. Postnatal imaging can assist in identifying associated abnormalities and dentofacial deformities. Dentofacial sequelae of cleft lip and palate include missing and supernumerary teeth, oronasal fistulas, velopharyngeal insufficiency, hearing loss, maxillary growth restriction, and airway abnormalities. Secondary deformities can often be found incidentally at imaging performed for other purposes, but detection is necessary because they may have considerable implications for the patient.

  17. Can we predict a difficult intubation in cleft lip/palate patients?

    To find predictors of a difficult intubation in infants with an isolated or a syndromic cleft lip/palate. Retrospective review: single-blind trial. Tertiary care centre. A total of 145 infants born with cleft lip/palate were enrolled. Three clinical and seven lip/palate anatomic parameters were evaluated. The grade of intubation was determined by the anesthesiologist at the time of the labioplasty/staphylorrhaphy surgery at 3 and 10 months, respectively. Intubation grade. The relative risk of a difficult intubation in the cleft lip, cleft palate without the Pierre Robin sequence, cleft lip-palate, and cleft palate with Pierre Robin sequence groups was 0, 2.7, 10, and 23%, respectively. The infants born with the Pierre Robin sequence had a statistically significant higher intubation grade. The degree of difficulty was increased in cases with early airway and feeding problems (p < .0001). Within the group of cleft palate patients without any lip malformation, a wider cleft was associated with a higher intubation grade with statistical significance (p  =  .0323). Infants born with Pierre Robin sequence have a statistically significantly higher risk of difficult intubation. Within this group, of all the studied factors, a clinical history of early airway and feeding problems was the best predictor of a difficult endotracheal intubation. In cleft palate patients without any cleft lip, larger width of the cleft is also a significant predictor.

    According to the 2014 Surgeon General's Report, smoking in early pregnancy can cause orofacial clefts. We sought to examine the implications of this causal link for the potential prevention of orofacial clefts in the United States. Using published data on the strength of the association between orofacial clefts and smoking in early pregnancy and the prevalence of smoking at the start of pregnancy, we estimated the attributable fraction for smoking as a cause of orofacial clefts. We then used the prevalence of orofacial clefts in the United States to estimate the number of orofacial clefts that could be prevented in the United States each year by eliminating exposure to smoking during early pregnancy. We also estimated the financial impact of preventing orofacial clefts caused by maternal smoking based on a published estimate of attributable healthcare costs through age 10 for orofacial clefts. The estimated attributable fraction of orofacial clefts caused by smoking in early pregnancy was 6.1% (95% uncertainty interval 4.4%, 7.7%). Complete elimination of smoking in early pregnancy could prevent orofacial clefts in approximately 430 infants per year in the United States, and could save an estimated $40.4 million in discounted healthcare costs through age 10 for each birth cohort. Understanding the magnitude of the preventable burden of orofacial clefts related to maternal smoking could help focus smoking cessation efforts on women who might become pregnant. © 2014 Wiley Periodicals, Inc.

    Clefts are common birth defects. They are accompanied by various malformations, including disturbances in facial look as well as skeletal disorders that include malocclusions, most frequently crossbites and class III anomalies. The aim of the study was to present the commonest malocclusions in patients with total cleft of the lip, alveolar bone and palate (n = 154) and compare the results to the healthy on-cleft patients (n = 151). Normal occlusion, characteristic for I angle class, was observed in 50% of the control group and 30% of the examined. In the examined patients with clefts, most frequently crossbite and open bite on the cleft side was observed. In patients with clefts, only 2 out of 154 patients presented isolated dental anomalies. In healthy individuals the commonest occlusal disorder was distal occlusion and dental anomalies. The commonest malocclusions among patients with clefts are crossbites and class III malocclusions.

    Cleft lip (CL) and cleft palate (CP) are common craniofacial abnormalities with an incidence of around 1:800. Surgical are corrections often performed during the first year of life. These patients have risks for difficult intubation and various perioperative complications due to their young age and craniofacial abnormalities. The purpose of the retrospective descriptive study is to report the data of anesthetic techniques and complications of repairing CLCP in Srinagarind Hospital. These results could improve the caring and services for these groups of patients. Data was retrieved from anesthetic records of patients undergoing correction of CLCP from the period January 2005 to January 2009. Demographic data, clinical diagnosis, type operation, anesthetic technique, total opiod were analyzed using direct laryngoscopic view, grading intubation, method of intubation, and as well perioperative complications were also analyzed. A total of 469 anesthetic records were obtained. The most common type of CLCP was unilateral side (45.48%). The highest incidence of difficult intubation was found in the CP and unilateral CLCP subgroup (4.48% and 4.48%, respectively). All patients were successfully intubated with a stylet except one patient, in whom retrograde intubation was used. Perioperative complications included desaturation, reintubation, postoperative bleeding, and post-operative nausea and vomiting (PONV). And the highest incidence of PONV was found in the CP (8.95%). Correlation between fentanyl using and postoperative desaturation was statistically significant when multivariate analysis was used (OR = 1.2; p = 0.01). Patients with unilateral CLCP or CP had a higher risk for difficult intubation. Fortunately, all of the patients were successfully intubated with advanced anesthetists' skill. Long operative periods and a large dose of opioid could contribute to the postoperative desaturation and PONV.

    To identify the interactions among two loci (C641A and G15572-) of transforming growth factor beta 3 (TGFbeta3), and exposures in pregnancy with cleft lip with/without cleft palate (CL/P), a hospital-based case-control study was conducted. Associations among offspring polymorphisms of TGFbeta3 C641A and G15572-, paternal smoking, paternal high-risk drinking, maternal passive smoking, and maternal multivitamin supplement with CL/P were analyzed by logistic regression analysis, and the results showed that maternal passive smoking exposures and maternal multivitamin use were associated with the risk of CL/P but offspring polymorphisms of TGFbeta3 C641A and G15572-, paternal smoking, and paternal high-risk drinking were not. Interactions among these variables were analyzed using the multifactor dimensionality reduction method, and the results showed that the two-factor model, including maternal passive smoking and TGFbeta3 C641A, among all models evaluated had the best ability to predict CL/P risk with a maximum cross-validation consistency (9/10) and a maximum average testing accuracy (0.5892; p = 0.0010). These findings suggested that maternal passive smoking exposure is a risk factor for CL/P, whereas maternal multivitamin supplement is a protective factor. The polymorphism of TGFbeta3 C641A participates in interaction effect for CL/P with environmental exposures, although the polymorphism was not associated with CL/P in single-locus analysis, and synergistic effect of TGFbeta3 C641A and maternal passive smoking could provide a new tool for identifying high-risk individuals of CL/P and also an additional evidence that CL/P is determined by both genetic and environmental factors.

    The transforming growth factor alpha (TGFA) Taq I polymorphism has been indicated to be correlated with cleft lip with or without cleft palate (CL/P) susceptibility, but study results are still debatable. Thus, a meta-analysis was conducted. We conducted a comprehensive search of Embase, Ovid, Web of Science, the Cochrane database, PubMed, the Chinese Biomedical Literature Database (CBM-disc, 1979-2014), the database of National Knowledge Infrastructure (CNKI, 1979-2014) and the full paper database of Chinese Science and Technology of Chongqing (VIP, 1989-2014) to identify suitable studies. There were 18 studies suitable for this meta-analysis, involving a total of 3135 cases and 3575 controls. Significantly increased CL/P risk was observed (OR = 1.49; 95% CI 1.17-1.89; P = 0.001). In subgroup analyses stratified by ethnicity, there was evidence in the Caucasian population for an association between this polymorphism and CL/P risk (OR = 1.52; 95% CI 1.14-2.02; P = 0.004). However, no significant association was found between this his polymorphism and CL/P risk in African and Hispanic populations. According to a specific CL/P type, increased clip lip and palate risk and clip palate risk were found (OR = 1.38; 95% CI 1.10-1.73; P = 0.005; OR = 1.29; 95% CI 1.01-1.66; P = 0.042). In conclusion, the present meta-analysis found that the TGFA Taq I polymorphism may be associated with CL/P susceptibility. PMID:26064247

    Sub-epithelial defects (i.e. discontinuities) of the superior orbicularis oris (OO) muscle appear to be a part of the phenotypic spectrum of cleft lip with or without cleft palate (CL±P). Analysis of the OO phenotype as a clinical tool is hypothesized to improve familial recurrence risk estimates of CL±P. Study subjects (n=3912) were drawn from 835 families. Occurrences of CL±P were compared in families with and without members with an OO defect. Empiric recurrence risks were calculated for CL±P and OO defects among first degree relatives (FDRs). Risks were compared to published data and/or to other outcomes of this study using chi square or Fisher's exact tests. In our cohort, the occurrence of CL±P was significantly increased in families with OO defects versus those without (p < 0.01, OR = 1.74). The total FDR recurrence of isolated OO defects in this cohort is 16.4%; the sibling recurrence is 17.2%. The chance for one or more FDRs of a CL±P proband to have an OO defect is 11.4%; or 14.7% for a sibling. Conversely, the chance for any FDR of an individual with an OO defect to have CL±P is 7.3%; or for a sibling, 3.3%; similar to published recurrence risk estimates of nonsyndromic (NS) CL±P. This study supports sub-epithelial OO muscle defects as being part of the CL±P spectrum and suggests a modification to recurrence risk estimates of CL±P by utilizing OO defect information.

To report the prevalence and the type of associated malformations in Northeastern Thai patients with cleft lip/palate. A retrospective study of 123 cleft lip/palate patients aged 4-5 years was carried out at the Tawanchai Cleft Center, Khon Kaen University during the periodfrom October to December 2011. Data were collected by reviewing the patients medical records. Seventeen (14%) of the 123patients had associated malformations. Four (21%) of the 19patients with cleft palate, eleven (15%) of the 74 patients with clefts lip and palate, and two (7%) of the 30 patients with cleft lip had associated malformations. The organ systems affected by associated malformations were cardiovascular system (41%), craniofacial anomaly (23%), skeletal system (12%), urogenital system (12%) and central nervous systemn (12%). Atrial septal defect and tetralogy ofFallot were most common associated cardiovascular malformation found. The high prevalence of associated malformationsfound in patients with cleft lip/palate emphasizes the needfor a thorough screening of associated malformations and congenital heart disease ofall cleft lip/palatepatients.

    The RYK, EPHB2, and EPHB3 genes are attractive candidates for cleft lip and/or palate and cleft palate only pathogenesis. Both the Ryk-deficient mouse and Ephb2/Ephb3 (genes for interaction molecules with RYK) double-mutant mouse show cleft palate. Mutation searches for RYK, EPHB2, and EPHB3 were carried out in a large number of Japanese and Vietnamese patients with cleft lip and/or palate and cleft palate only. Case-control study and transmission disequilibrium tests were performed also, using three single nucleotide polymorphisms within a linkage disequilibrium block in RYK. Seven haplotypes were constructed from the single nucleotide polymorphisms. A missense mutation, 1355G>A (Y452C), in RYK was identified in one Vietnamese patient with cleft lip and/or palate. This mutation was not found among 1646 Vietnamese, Japanese, and Caucasians, including 354 cleft lip and/ or palate and cleft palate only patients. Colony formation assay using NIH3T3 cells transfected with mutant cDNA revealed that mutant RYK had significantly reduced protein activity, compared with those with wild-type RYK, implying that the transformation ability of RYK is depleted by this mutation. Although a case-control study and transmission disequilibrium tests on three individual single nucleotide polymorphisms provided no evidence for association with oral clefts, a case-control study on one rare haplotype suggested a positive association in Japanese patients with cleft lip and/or palate and cleft palate only. No mutations in EPHB2 and EPHB3 were found in any patients examined. The findings suggested that a missense mutation, 1355G>A, and one rare single nucleotide polymorphisms haplotype may play a role in the development of cleft lip and/or palate in the Vietnamese, and cleft lip and/ or palate and cleft palate only in the Japanese.

    In this study of infants with isolated birth defects, 69 cleft palate-only (CPO) cases, 114 cleft lip with or without palate (CL/P), and 284 controls with non-cleft birth defects (all born in Maryland during 1984-1992) were examined to test for associations among genetic markers and different oral clefts. Modest associations were found between transforming growth factor {alpha} (TGF{alpha}) marker and CPO, as well as that between D17S579 (Mfd188) and CL/P in this study. The association between TGF{alpha} marker and CPO reflects a statistical interaction between mother`s smoking and child`s TGF{alpha} genotype. A significantly higher risk of CPO was found among those reporting maternal smoking during pregnancy and carrying less common TGF{alpha} TaqI allele (odds ratio=7.02 with 95% confidence interval 1.8-27.6). This gene-environment interaction was also found among those who reported no family history of any type of birth defect (odds ratio=5.60 with 95% confidence interval 1.4-22.9). Similar associations were seen for CL/P, but these were not statistically significant.

    Interdental clefts or invaginations contribute to orthodontic relapse and poor periodontal health in extraction cases. These clefts or invaginations can be removed both by electrosurgical or conventional surgical gingivectomy techniques. This study investigates and compares the efficacy of two different techniques to remove gingival clefts with respect to periodontal health and patient tolerance. Twenty-two patients (mean age, 15.7 years) with bilateral gingival clefts participated in this study. In each patient, the gingival invaginations were removed by gingivectomy using electrosurgery on one side and conventional surgery on the contralateral side. The length and depth of the invaginations, the gingival index of the adjacent teeth, and the changes in visual analogue scale scores were recorded before and after the operation for both groups. Mann-Whitney U-test and Wilcoxon tests were used to analyze the data statistically. The results showed significant improvement in invagination depth and length and gingival index scores for both techniques. There were no statistical differences between the two gingivectomy techniques with respect to gingival health and patient tolerance. Both techniques can be used to remove the gingival invaginations efficiently.

    In many patients, the volume of the upper lip is deficient after cleft lip repair operation. However, there is no well-established procedure to correct this volume deficiency. In the present study, the authors attempted to increase the overall three-dimensional volume of the upper lip in repaired cleft lip patients with upper lip volume deficiency through autogenous microfat grafting. Thirty patients with upper lip volume deficiency after cleft lip repair underwent fat grafting in the upper lip from November 2007 to March 2015. Among these patients, postoperative outcome was evaluated in 15 patients using 2 methods for the evaluation. One method involved measuring the change in the shape of lips using pre- and postoperative photographs, and the other involved investigating the levels of satisfaction with the surgical results by distributing a scoring questionnaire to patients, doctors, and the general public. The ratio of upper lip protrusion relative to the lower lip increased by 46.71% on average after operation, and the sum of the vermilion heights increased by 31.68% on average. In the survey of satisfaction levels, patients, plastic surgeons, and the general public gave mean scores of 3.80, 3.91, and 4.03, respectively. When volume deficiency of the upper lip is present in repaired cleft lip patients, correction using autogenous microfat grafting is believed to be effective.

    The purpose of our retrospective review is to examine our method and outcomes for the application of octyl-2-cyanoacrylate for the repair of primary and revision cleft lips in both pediatric and adult patients. Records and photographs were reviewed and analyzed for patient age, type of cleft, revision or primary repair, complications, length of follow-up, and aesthetic outcomes. Eighteen patients, both children and adults, who underwent cleft lip repairs using tissue adhesive performed by a single surgeon between 1999 and 2003 were included. Twelve patients underwent primary repair and 6 patients underwent revision repair. Repairs were performed using the Millard rotation advancement technique and the Mohler variant. The lateral advancement flap was kept long and redundant in its transverse dimension to create a pressure fit everting the skin edges with minimal sutures to set up the closure for application of the tissue adhesive. Seventeen of eighteen patients had excellent cosmetic outcomes. One patient had minor necrosis of the tip of the advancement flap. No allergic reactions, wound infections, or dehiscences occurred. The use of octyl-2-cyanoacrylate for the skin closure of primary and revision cleft lip repairs in both children and adults results in excellent cosmetic outcomes. Employing our pressure-fit technique for skin eversion prior to application of the tissue adhesive may be advantageous. The lack of suture removal in the pediatric population and decreased operative time are additional benefits.

    It is important to predict and prevent the impaction of canines. The aim of this study was to estimate the prevalence of impacted canines in patients with unilateral cleft lip and palate (UCLP) and to identify factors associated with impaction. This retrospective cohort study included patients with nonsyndromic UCLP. The predictors were pre-eruptive inclination angle, deviation in tooth number (agenesis or supernumerary lateral incisors), and reoperation of bone transplant. The outcome variable was impacted and surgically exposed canines. The prevalence of impacted and surgically exposed canines in the 68 consecutive patients with UCLP was 20.6%. The pre-eruptive inclination angle was significantly larger (34.4°) for the impacted canines on the cleft side compared with the spontaneously erupted canines on the cleft and non-cleft sides (25.5° vs 15.4; P < .05). Reoperation of the bone transplant significantly increased canine impaction (50%; P < .05). The eruption of maxillary canines needs to be supervised carefully in patients with UCLP, because the prevalence of impaction is 10 times higher compared with the general population. Factors associated with canine impaction are a pre-eruptive inclination larger than 30° and reoperation of the bone transplant.

    Diagnosis and treatment of type 1 laryngeal clefts remains a challenge. The purpose of this study is to determine if early surgical intervention in type I laryngeal clefts improves outcomes. A retrospective case series was conducted at an academic tertiary care children's hospital. 18 children undergoing early (≤3 months from diagnosis) surgical intervention for type I laryngeal cleft repair between August of 2012 and December 2014. Data was compiled through a manual chart review. 18 children who underwent early surgical intervention for type I laryngeal cleft repair were identified for review. 14 (78%) were male and 4 (22%) were female and the average age at time of repair was 1.6 years. Most frequent presenting symptoms included dysphagia (61%) and recurrent respiratory issues (22%). Successful swallowing outcomes, defined as subjective improvement (i.e. absence of previous symptoms) per parental report in follow-up visits, +/- normal post-operative MBS (modified barium swallow) findings, was seen in 11 patients (61%). 9 patients required hospitalization for respiratory issues prior to surgical repair. Post-operatively, 4 patients still incurred an admission for respiratory reasons. Our series shows a success rate of 61% with early surgical intervention (≤3 months from diagnosis). A decrease in post-operative hospitalizations is appreciated. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    Structured Abstract Objectives To describe the perceptual speech outcomes from the Cleft Care UK (CCUK) study and compare them to the 1998 Clinical Standards Advisory Group (CSAG) audit. Setting and sample population A cross-sectional study of 248 children born with complete unilateral cleft lip and palate, between 1 April 2005 and 31 March 2007 who underwent speech assessment. Materials and methods Centre-based specialist speech and language therapists (SLT) took speech audio–video recordings according to nationally agreed guidelines. Two independent listeners undertook the perceptual analysis using the CAPS-A Audit tool. Intra- and inter-rater reliability were tested. Results For each speech parameter of intelligibility/distinctiveness, hypernasality, palatal/palatalization, backed to velar/uvular, glottal, weak and nasalized consonants, and nasal realizations, there was strong evidence that speech outcomes were better in the CCUK children compared to CSAG children. The parameters which did not show improvement were nasal emission, nasal turbulence, hyponasality and lateral/lateralization. Conclusion These results suggest that centralization of cleft care into high volume centres has resulted in improvements in UK speech outcomes in five-year-olds with unilateral cleft lip and palate. This may be associated with the development of a specialized workforce. Nevertheless, there still remains a group of children with significant difficulties at school entry. PMID:26567854

    Manyspeakers with cleft palate develop atypical consonant productions, especially for pressure consonants such as plosives, fricatives, and affricates. The present study investigated the nature of nasal sound errors. The participants were eight female and three male speakers with cleft palate between the ages of 6 to 20. Speakers were audio-recorded, and midsagittal tongue movement was captured with ultrasound. The speakers repeated vowel-consonant-vowel with the vowels /α/, /i/, and /u/ and the alveolar and velar nasal consonants /n/ and //. The productions were reviewed by three listeners. The participants showed a variety of different placement errors and insertions of plosives, as well as liquid productions. There was considerable error variability between and within speakers, often related to the different vowel contexts. Three speakers co-produced click sounds. The study demonstrated the wide variety of sound errors that some speakers with cleft palate may demonstrate for nasal sounds. Nasal sounds, ideally in different vowel contexts, should be included in articulation screenings for speakers with cleft palate, perhaps more than is currently the case.

    To compare the effect of secondary alveolar bone graft (SABG) on the tooth development stage of the maxillary central incisor (MXCI) and maxillary canine (MXC) in terms of the severity of unilateral cleft. The subjects consisted of 50 boys with unilateral cleft lip and alveolus (UCLA) or unilateral cleft lip, alveolus, and palate (UCLP). The age- and sex-matched subjects were divided into group 1 (UCLA, n = 25; 9.3 ± 0.8 years old) and group 2 (UCLP, n = 25; 9.4 ± 0.6 years old). In panoramic radiographs taken 1 month before (T0) and 1 year after SABG (T1), tooth development stage was evaluated according to the Nolla developmental (ND) stage. A panoramic radiograph taken 3 years after SABG was used as a reference for the final root length of individual tooth. In groups 1 and 2, the ND stage of the MXCI did not exhibit differences between the cleft and non-cleft sides at T0 and T1, respectively. However, although the ND stage of the MXC of group 2 was delayed on the cleft side compared with the non-cleft side at T0 (P < .05), the MXC on the cleft side developed faster than that on the non-cleft side after SABG (P < .01). In terms of tooth development speed, group 2 showed a higher rate of faster developed MXCs on the cleft side compared with the non-cleft side after SABG than group 1 (36.0% vs 8.0%, P < .05). SABG performed at approximately 9 years of age might increase tooth development speed of MXC in patients with UCLP compared with patients with UCLA.

    Introduction To evaluate, using cone-beam computed tomography (CBCT), both the condylar-fossa relationships and the mandibular and condylar asymmetries between unilateral cleft lip and palate (UCLP) patients and non-cleft patients with class III skeletal relationship, and to investigate the factors of asymmetry contributing to chin deviation. Methods The UCLP and non-cleft groups consisted of 30 and 40 subjects, respectively, in mixed dentition with class III skeletal relationships. Condylar-fossa relationships and the dimensional and positional asymmetries of the condyles and mandibles were examined using CBCT. Intra-group differences were compared between two sides in both groups using a paired t-test. Furthermore, correlations between each measurement and chin deviation were assessed. Results It was observed that 90% of UCLP and 67.5% of non-cleft subjects had both condyles centered, and no significant asymmetry was found. The axial angle and the condylar center distances to the midsagittal plane were significantly greater on the cleft side than on the non-cleft side (P=0.001 and P=0.028, respectively) and were positively correlated with chin deviation in the UCLP group. Except for a larger gonial angle on the cleft side, the two groups presented with consistent asymmetries showing shorter mandibular bodies and total mandibular lengths on the cleft (deviated) side. The average chin deviation was 1.63 mm to the cleft side, and the average absolute chin deviation was significantly greater in the UCLP group than in the non-cleft group (P=0.037). Conclusion Compared with non-cleft subjects with similar class III skeletal relationships, the subjects with UCLP showed more severe lower facial asymmetry. The subjects with UCLP presented with more asymmetrical positions and rotations of the condyles on axial slices, which were positively correlated with chin deviation. PMID:26237311

    Few reports have been published on the early microbiota in infants with various types of cleft palate. We assessed the formation of the oral microbiota in infants with complete cleft lip and palate (CLP n = 30) or cleft soft palate (CSP n = 25) in the neonatal period (T1 time) and again in the gum pad stage (T2 time). Culture swabs from the tongue, palate, and/or cleft margin at T1 and T2 were taken. We analysed the prevalence of the given bacterial species (the percentage) and the proportions in which the palate and tongue were colonised by each microorganism. At T1, Streptococcus mitis (S. mitis) were the most frequently detected in subjects with CLP or CSP (63% and 60%, resp.). A significantly higher frequency of methicillin-sensitive Staphylococcus aureus (S. aureus MSSA) was observed in CLP compared to the CSP group. At T2, significantly higher percentages of S. mitis, S. aureus MSSA, Staphylococcus epidermidis, and members of the Enterobacteriaceae family were noted in CLP infants compared to the CSP. S. mitis and Streptococcus sanguinis appeared with the greatest frequency on the tongue, whereas Streptococcus salivarius was predominant on the palate. The development of the microbiota in CLP subjects was characterised by a significant increase in the prevalence of pathogenic bacteria. PMID:28393073

    To determine the frequency of the transforming growth factor-alpha (TGFalpha) Taq1 polymorphism in nonsyndromic cleft lip with or without cleft palate (CL+/-P) and cleft palate only (CP) in Kelantan, Malaysia. The study was conducted at the Combined Cleft Clinic and at the Human Genome Centre in Hospital Universiti Sains Malaysia in Kelantan, Malaysia. We examined the C2/Taq1 variant of the TGFalpha gene in 46 patients with nonsyndromic CL+/-P or CP only and in 33 controls. The TGFalpha genotype frequencies in patients were compared with those in controls using the chi-square or Fisher exact test. DNA samples were obtained from peripheral blood. No association was found between TGFalphaTaq1 polymorphism and CL+/-P or CP in this case-control study. In addition, no homozygosity for the rare allele C2 was noted in CL+/-P, CP, or the controls. No evidence of TGFalphaTaq1 polymorphism was observed in association with CL+/-P and CP in this study.

    Nonsyndromic cleft lip with or without cleft palate (CL/P) is a common birth defect due to both genetic and environmental factors. Whorl lip print patterns are circular grooves on the central upper lip and/or the left and right lower lip. To determine if whorls are more common in families with CL/P than in controls, the Pittsburgh Orofacial Cleft Study collected lip prints from over 450 subjects, i.e., individuals with CL/P, their relatives, and unrelated controls—from the U.S., Argentina, and Hungary. Using a narrow definition of lower-lip whorl, the frequency of whorls in the U.S sample was significantly elevated in cleft individuals and their family members, compared to unrelated controls (14.8% and 13.2% versus 2.3%; P = 0.003 and 0.001, respectively). Whorls were more frequent in CL/P families from Argentina than in CL/P families from the U.S. or Hungary. If these results are confirmed, whorl lip print patterns could be part of an expanded phenotypic spectrum of nonsyndromic CL/P. As such, they may eventually be useful in a clinical setting, allowing recurrence risk calculations to incorporate individual phenotypic information in addition to family history data. PMID:19921634

    2015-06-01

    The management of cleft lip, alveolar and palate sequelae remains problematic today. To optimize it, we tried to establish a new clinical index for diagnostic and prognostic purposes. Seven tissue indicators, that we consider to be important in the management of alveolar sequelae, are listed by assigning them individual scores. The final score, obtained by adding together the individual scores, can take a low, high or maximum value. We propose a new classification (ACS: Alveolar Cleft Score) that guides the therapeutic team to a prognosis approach, in terms of the recommended surgical and prosthetic reconstruction, the type of medical care required, and the preventive and supportive therapy to establish. Current studies are often only based on a standard radiological evaluation of the alveolar bone height at the cleft site. However, the gingival, the osseous and the cellular areas bordering the alveolar cleft sequelae induce many clinical parameters, which should be reflected in the morphological diagnosis, to better direct the surgical indications and the future prosthetic requirements, and to best maintain successful long term aesthetic and functional results.

    Genome wide association (GWA) studies have successfully identified at least a dozen loci associated with orofacial clefts. However, these signals may be unique to specific populations and require replication to validate and extend findings as a prelude to etiologic SNP discovery. We attempted to replicate the findings of a recent meta-analysis of orofacial cleft GWA studies using four different ancestral populations. We studied 946 pedigrees (3436 persons) of European (US white and Danish) and Asian (Japanese and Mongolian) origin. We genotyped six SNPs which represented the most significant P value associations identified in published studies: rs742071 (1p36), rs7590268 (2p21), rs7632427 (3p11.1), rs12543318 (8q21.3), rs8001641 (13q31.1) and rs7179658 (15q22.2). We directly sequenced three non-coding conserved regions 200kb downstream of SPRY2 in 713 cases, 438 controls, and 485 trios from the US, Mongolia, and the Philippines. We found rs8001641 to be significantly associated with cleft lip with cleft palate (NSCLP) in Europeans (p-value=4 × 10−5, ORtransmission=1.86 with 95% confidence interval: 1.38-2.52). We also found several novel sequence variants in the conserved regions in Asian and European samples, which may help to localize common variants contributing directly to the risk for NSCLP. This study confirms the prior association between rs8001641 and NSCLP in European populations. PMID:25786657

    Reports after the 2005 Hurricane Katrina have documented an increase in stress reactions and environmental teratogens (arsenic, mold, alcohol). To assess the incidence of cleft pathology before and after the hurricane, and the distribution of cleft cases by gender and race. Retrospective chart review of cleft lip with or without cleft palate (CL/P) and cleft palate (CP) cases registered with the Cleft and Craniofacial Team at Children's Hospital of New Orleans, the surgical center that treated cleft cases in Greater New Orleans between 2004 and 2007. Live birth data were obtained from the Louisiana State Center for Health Statistics. The incidence of cleft cases, beginning 9 months after the hurricane (i.e., June 1, 2006) was significantly higher compared with the period before the hurricane (0.80 versus 1.42; p = .008). Within racial group comparisons showed a higher incidence among African Americans versus whites (0.42 versus 1.22; p = .01). The distribution of CL/P and CP cases by gender was significant (p = .05). The increase in the incidence of cleft cases after the hurricane may be attributable to increased stress and teratogenic factors associated with the hurricane. The increase among African Americans may have been due to comparatively higher exposure to environmental risk factors. These findings warrant further investigation to replicate the results elsewhere in the Gulf to determine whether there is a causal relationship between environmental risk factors and increased cleft pathology.

    To compare the performance in the abilities of receptive and expressive language of children with cleft lip and palate with that of children without cleft lip and palate with typical 12 to 36-month chronological development. The sample consisted of 60 children aged 12 and 36 months: 30 with cleft lip and palate diagnosis and 30 without cleft lip and palate diagnosis with typical development. The groups were paired according to gender, age (in months), and socioeconomic level. The procedures consisted of analysis of medical records, anamnesis with family members, and valuation of the Early Language Milestone Scale (ELMS). The chart analysis showed 63.34% of the children with unilateral cleft lip and palate, 16.66% with bilateral incisive transforamen cleft, and 20% with post-foramen cleft. Children with cleft lip and palate underwent surgeries (lip repair and/or palatoplasty) at the recommended ages and participated in early intervention programs; 40% presented recurrent otitis history, and 50% attended schools. Statistical analysis included the use of the Mann Whitney test with significance level of p <0.05. There was a statistically significant difference between the groups regarding receptive and expressive skills. The group of children with cleft lip and palate showed statistically significant low performance in receptive and expressive language compared with children without cleft lip and palate.

    Aim: The study aims to determine the frequency of homologous blood transfusion in patientsundergoing cleft lip and palate surgery at the Lagos University Teaching Hospital, Nigeria. Setting and Design: A prospective study of transfusion rate in cleft surgery conducted at the Lagos University Teaching Hospital, Nigeria. Material and Methods: One hundred consecutive patients who required cleft lip and palate surgery were recruited into the study. Data collected included age, sex and weight of patients, type of cleft defects, type of surgery done, preoperative haematocrit, duration of surgery, amount of blood loss during surgery, the number of units of blood cross-matched and those used. Each patient was made to donate a unit of homologous blood prior to surgery. Results: There were 52 females and 48 males with a mean age of 64.4 ± 101.1 months (range, 3-420 months). The most common cleft defect was isolated cleft palate (45%) followed by unilateral cleft lip (28%). Cleft palate repair was the most common procedure (45%) followed by unilateral cleft lip repair (41%). The mean estimated blood loss was 95.8 ± 144.9 ml (range, 2-800ml). Ten (10%) patients (CL=2; CP=5, BCL=1; CLP=2) were transfused but only two of these were deemed appropriate based on percentage blood volume loss. The mean blood transfused was 131.5 ± 135.4ml (range, 35-500ml). Six (60%) of those transfused had a preoperative PCV of < 30%. Only 4.9% of patients who had unilateral cleft lip surgery were transfused as compared with 50% for CLP surgery, 11% for CP surgery, and 10% for bilateral cleft lip surgery. Conclusions: The frequency of blood transfusion in cleft lip and palate surgery was 10% with a cross-match: transfusion ratio of 10 and transfusion index of 0.1. A "type and screen" policy is advocated for cleft lip and palate surgery. PMID:20924451

    The first association study of cleft lip with or without cleft palate (CL/P), with candidate genes, found an association with the transforming growth-factor alpha (TGFA) locus. This finding has since been replicated, in whole or in part, in three independent studies. Here the authors extend their original analysis of the TGFA TaqI RFLP to two other TGFA RFLPs and seven other RFLPs at five candidate genes in 117 nonsyndromic cases of CL/P and 113 controls. The other candidate genes were the retinoic acid receptor (RARA), the bcl-2 oncogene, and the homeobox genes 2F, 2G, and EN2. Significant associations with the TGFA TaqI and BamHI RFLPs were confirmed, although associations of clefting with previously reported haplotypes did not reach significance. Of particular interest, in view of the known teratogenic role of retinoic acid, was a significant association with the RARA PstI RFLP (P = .016; not corrected for multiple testing). The effect on risk of the A2 allele appears to be additive, and although the A2A2 homozygote only has an odds ratio of about 2 and recurrence risk to first-degree relatives ([lambda][sub 1]) of 1.06, because it is so common it may account for as much as a third of the attributable risk of clefting. There is no evidence of interaction between the TGFA and RARA polymorphisms on risk, and jointly they appear to account for almost half the attributable risk of clefting. 43 refs., 1 fig., 4 tabs.

    Cleft lip with or without cleft palate (CL/P) is a common congenital anomaly, with birth prevalence ranging from 1/500 to 1/1,000. A number of genetic loci have shown positive linkage or association results in European Caucasian populations. The purpose of the current study was to assess whether any of those loci have positive results in Turkish Caucasian CL/P families, and to perform a 10 cM genome scan to identify other regions potentially containing cleft susceptibility loci. Eighteen affected individuals with consanguineous parents were identified as part of our on-going studies of orofacial clefts in Ankara, Turkey. Genotyped were 383 genome-scan markers, and 70 additional markers, including markers in six candidate loci or regions on chromosomes 2, 4, 6, 14, 17, and 19 (TGFA, D4S175, F13A1, TGFB3, D17S250, and APOC2) that have been implicated in other studies of families with orofacial clefting. LOD scores (two point and multiple point) and family-based association statistics (TDT) were calculated between each of the markers and CL/P. For the LOD score calculations, an autosomal recessive model was assumed for the inheritance of CL/P. Of the six candidate markers, significant TDT results were obtained with TGFA (P = 0.05). The most statistically significant multipoint results from the linkage genome scan were between putative genes controlling risk of CL/P and regions on chromosomes 4, 10, 12, and 15 (maximum multipoint HLOD's of 1.25, 1.30, 2.73, and 1.28 respectively). These results demonstrate the power of small numbers of families with inbred probands to detect linkage and association. Copyright 2003 Wiley-Liss, Inc.

    Pre-speech in 35 children with clefts of the lip and palate or palate only were analyzed for place and manner of articulation. Transcriptions were made from tape recorded babbling sequences. Two children without clefts were used as reference. All of the children with clefts were treated according to a regimen of early surgical repair of the velum cleft and delayed closure of the cleft in the hard palate. The frequency of selected phonetic features was calculated. Correlations between phonetic/perceptual and functional and morphological factors were tested. Supraglottal articulation dominated among all the children indicating a sufficient velopharyngeal mechanism. The results also showed correlations between cleft type and place of articulation. Anteriorly placed sounds (i.e., bilabial, dental, and alveolar sounds) occurred frequently among the children with cleft palate only and in the noncleft children. In children with cleft lip and palate, posteriorly placed articulations predominated. It was postulated that early intervention may have a positive effect on articulatory development.

      The purpose of this project was to develop objective computer-based methods to measure nasal asymmetry and abnormality in children undergoing treatment of unilateral cleft lip (UCL) and to determine the correlation of these measures to clinical expectations.   Thirty infants with UCL undergoing cleft lip repair; 27 children with UCL aged 8 to 10 years who had previously undergone cleft lip repair; 3 control infants; 3 control children aged 8 to 10 years.   To measure nasal symmetry, we used a process of depth mapping and calculated the Depth Area Difference. To measure abnormality, we used the reconstruction error from Principle Component Analysis (PCA) that was based upon characteristics of a dataset of over 2000 images of normal control subjects.   Depth Area Difference and PCA Reconstruction Error for cleft type, changes with surgery, and individual subjects ranked according to cleft severity were assessed.   Significant differences in Depth Area Difference and PCA Reconstruction Error were found between cleft types and found before and after surgery. Nasal symmetry and normalcy scores for infants with UCL approached those of controls after surgery, and there was a strong correlation with ranked cleft severity. For older children, measures of nasal symmetry and abnormality were better than infants prior to repair but worse than infants following UCL repair.   Our computer-based 3D analysis of nasal symmetry and normalcy correlated with clinical expectations. Automated processing made measurement convenient. Use of these measures may help to objectively measure cleft severity and treatment outcome.

    To examine the accuracy and timing of diagnosis of fetal cleft lip with or without cleft palate (CL ± P) in the years following the introduction of a national screening program, and to assess the completeness and accuracy of information in The Netherlands Perinatal Registry. A list was obtained of cases with a prenatal or postnatal diagnosis of CL ± P from two fetal medicine units between 2008 and 2012. All cases of CL ± P were included irrespective of the presence or absence of additional anomalies. Cases were included if the estimated date of delivery was between 1 January 2008 and 31 December 2012. During the study period, 330 cases of CL ± P were identified, with a prevalence of 15 per 10 000 pregnancies. The number of cases that were detected before 24 weeks' gestation increased during the study period, while the rate of termination of pregnancy did not change significantly (P = 0.511). CL ± P was isolated in 217 (66%) cases and karyotype was abnormal in 69 (21%) cases. In 5% of the cases in which CL ± P seemed to be isolated during the 18-23-week anomaly scan, postnatal array comparative genomic hybridization (array-CGH) revealed an abnormal karyotype and 50% of these cases had major additional anomalies. Examination of data from The Netherlands Perinatal Registry demonstrated that in 37% of cases CL±P was not recorded in the pregnancy records. CL ± P is increasingly being diagnosed prenatally, without a significant effect on the rate of pregnancy termination. Further improvement in the diagnostic accuracy may be achieved by advocating prenatal array-CGH to reduce the frequency of unexpected anomalies being diagnosed after birth. It is important that healthcare providers register accurately the presence or absence of anomalies in the birth records to ensure that, in the future, data from The Netherlands Perinatal Registry can be relied upon to monitor prevalence.

    The author presents a 20-year experience leading cleft lip and palate surgical volunteer missions in Peru for CIRPLAST, a nonprofit volunteer plastic surgery goodwill program that has provided free surgery for patients with cleft lip and palate deformities in remote areas of Peru. Surgical procedures were performed by the author, together with a group of experienced plastic surgeons, under the auspices of the Peruvian Plastic Surgery Society, and local health authorities. CIRPLAST missions are scheduled annually in different locations around Peru. Selected patients for surgery after adequate screening are photographed, and their cleft deformity is recorded. Scheduled patients or their parents, when they are minors, sign an informed consent form. Patients operated on in any given day are examined and photographed 1 day after surgery, before discharge. Between 30 and 35 patients are operated on at each mission site. About 2 weeks after the mission, patients are checked and photographed, and the outcome of surgery is recorded. Complications that may occur are recorded and treated by the CIRPLAST team as soon as possible. Almost all operations are performed under general endotracheal anesthesia coupled by local anesthesia containing a vasoconstrictor, to reduce bleeding and facilitate tissue dissection. All wounds of the lip and palate are closed with absorbable sutures, to avoid the need for suture removal. After cleft lip surgery, patients go to the recovery room for monitoring by nurses until they recover completely. A total of 6108 cleft lip and palate repairs, primary and secondary, were performed by CIRPLAST in 141 missions, between May 12, 1994, and October 15, 2014. The medical records of the 5162 patients (84.5%) who returned for follow-up (ranging from 12 days to 9 years) were reviewed retrospectively. Between 45% and 70% of the patients operated on a mission have returned for early follow-up and some the following year. There were 3176 males (51.9%) and 2932

    Objective : To describe the epidemiology of orofacial clefts in the east of Ireland. Design and Setting : A descriptive epidemiologic study on 851 cases of orofacial cleft identified over a 25-year period from 1984 to 2008 from more than 500,000 births. Results : There were 438 (51.5%) cases of cleft lip with or without cleft palate and 413 (48.5%) cases of cleft palate. The total birth prevalence was 16.0 per 10,000 births for all orofacial clefts, 8.2 for cleft lip with or without cleft palate, and 7.8 for cleft palate. Of all cases, 63.7% (542/851) occurred as isolated anomalies, 21.5% (183/851) were associated with multiple anomalies, and 14.8% (126/851) were associated with a syndrome or chromosomal anomaly. A significantly increasing trend over the 25-year period was observed for cleft lip with or without cleft palate associated with syndromes or chromosomal anomalies among mothers younger than 35 years but not in those older than 35 years. Conclusion : A slightly higher rate of orofacial clefts was observed in the east of Ireland than was observed in European and multinational studies during the study period, and there were higher rates of cleft palate. The rising trend in the proportion of mothers aged 35 years or older in Ireland is not contributing significantly to orofacial clefts associated with chromosomal syndromes.

    Chenevix-Trench et al. (1992) reported a significant difference between nonsyndromic cleft lip with or without cleft palate (CL [+-] P) cases and unrelated controls in the frequency of alleles at the retinoic acid receptor alpha (RARA) PstI RFLP located at 17q21.1. They also observed borderline significant (P = .055) differences between allele frequencies in subjects with cleft lip and palate (CL + P) compared with those with cleft lip only (CL). Retinoic acid (RA) is a known teratogen capable of producing cleft palate in rodents (Abbott and Birnbaum 1990). Chenevix-Tench et al. (1992) hypothesized that variation in susceptibility to the effects of RA in humans may result from alterations at the RARA locus. We have investigated association and linkage between CL [+-] P and a microsatellite marker (D17S579) located at 17q21 (Hall et al. 1992), selected for its proximity to RARA, in 14 extended multiplex families from rural West Bengal, India.

    Zinc, a transition metal existing in very high concentrations in the hippocampal mossy fibers from CA3 area, is assumed to be co-released with glutamate and to have a neuromodulatory role at the corresponding synapses. The synaptic action of zinc is determined both by the spatiotemporal characteristics of the zinc release process and by the kinetics of zinc binding to sites located in the cleft area, as well as by their concentrations. This work addresses total, free and complexed zinc concentration changes, in an individual synaptic cleft, following single, short and long periods of evoked zinc release. The results estimate the magnitude and time course of the concentrations of zinc complexes, assuming that the dynamics of the release processes are similar to those of glutamate. It is also considered that, for the cleft zinc concentrations used in the model (≤ 1 μM), there is no postsynaptic zinc entry. For this reason, all released zinc ends up being reuptaken in a process that is several orders of magnitude slower than that of release and has thus a much smaller amplitude. The time derivative of the total zinc concentration in the cleft is represented by the difference between two alpha functions, corresponding to the released and uptaken components. These include specific parameters that were chosen assuming zinc and glutamate co-release, with similar time courses. The peak amplitudes of free zinc in the cleft were selected based on previously reported experimental cleft zinc concentration changes evoked by single and multiple stimulation protocols. The results suggest that following a low amount of zinc release, similar to that associated with one or a few stimuli, zinc clearance is mainly mediated by zinc binding to the high-affinity sites on the NMDA receptors and to the low-affinity sites on the highly abundant GLAST glutamate transporters. In the case of higher zinc release brought about by a larger group of stimuli, most zinc binding occurs

    Background: Volumetric analysis of the olfactory cleft by using computed tomography has been associated with olfaction in patients with chronic rhinosinusitis (CRS). However, existing studies have not comprehensively measured olfaction, and it thus remains unknown whether correlations differ across specific dimensions of odor perception. Objective: To use comprehensive measures of patient-reported and objective olfaction to evaluate the relationship between volumetric olfactory cleft opacification and olfaction. Methods: Olfaction in patients with CRS was evaluated by using “Sniffin' Sticks” tests and a modified version of the Questionnaire of Olfactory Disorders. Olfactory cleft opacification was quantified by using two- and three-dimensional, computerized volumetric analysis. Correlations between olfactory metrics and olfactory cleft opacification were then calculated. Results: The overall CRS cohort included 26 patients without nasal polyposis (CRSsNP) (68.4%) and 12 patients with nasal polyposis (CRSwNP) (31.6%). Across the entire cohort, total olfactory cleft opacification was 82.8%, with greater opacification in the CRSwNP subgroup compared with CRSsNP (92.3 versus 78.4%, p < 0.001). The percent total volume opacification correlated with the total Sniffin' Sticks score (r = −0.568, p < 0.001) as well as individual threshold, discrimination, and identification scores (p < 0.001 for all). Within the CRSwNP subgroup, threshold (r = −0.616, p = 0.033) and identification (r = −0.647, p = 0.023) remained highly correlated with total volume opacification. In patients with CRSsNP, the threshold correlated with total volume scores (r = −0.457, p = 0.019), with weaker and nonsignificant correlations for discrimination and identification. Correlations between total volume opacification and the Questionnaire of Olfactory Disorders were qualitatively similar to objective olfactory findings in both CRSwNP (r = −0.566, p = 0.070) and CRSsNP (r = −0.310, p

    Amphiphilic lipids associate in water spontaneously to form micelles, vesicles, monolayers, or biological membranes. These aggregates are soft and their shape can be changed easily. They behave like complex fluids because they are merely held together by weak, nondirected forces. The most important characteristic of these monolayers is their ability to dissolve hydrophobic molecules in the form of freely movable monomers. The fluid molecular layers are not suitable to anchor the components of chain reactions. However, if the alkyl chains are replaced by rigid skeletons or if the head groups are connected through intermolecular interactions, the aggregates become rigid and their fluid solvent character is lost. The construction of chiral surfaces by synkinesis (synthesis of noncovalent compounds) and of enzyme-type surface clefts of defined size can now be carried out by using rigid lipid membranes. Monolayers and nanometer pores on solid substrates attain sharp edges, and upright nanometer columns on smooth surfaces no longer dissipate. Five examples illustrate the advantages of using rigid molecular assemblies: 1) Cationic domains of rigid edge amphiphiles in fluid membranes act as manipulable ion channels. 2) Spherical micelles, micellar helical fibers, and vesicular tubes can be dried and stored as stable material. Molecular landscapes form on smooth surfaces. 3) alpha,omega-Diamide bolaamphiphiles form rigid nanometer-thick walls on smooth surfaces and these barriers cannot be penetrated by amines. Around steroids and porphyrins, they form rigid nanometer clefts whose walls and water-filled centers can be functionalized. 4) The structure of rigid oligophenylene- and quinone monolayers on electrodes can be changed drastically and reversibly by changing the potential. 5) 10(10) Porphyrin cones on a 1-cm2 gold electrode can be controlled individually by AFM- and STM-tips and investigated by electrochemical, photochemical, and mechanical means.

    Good results in any surgical or orthodontic procedure require expert technique, well adapted to the problem and scrupulously executed. A technique that would achieve the best results can be described as "ideal" and can serve as a theoretical model for all similar cases. But, in dealing with apparently similar problems: cleft lips and palates, Class II or Class III cases... in reality, we are treating individual patients, none quite the same as any other. These differences derive from the varying characteristics of individual patients and from the varying and unpredictable responses of their tissues, and from their varying capacities to accommodate to and withstand insults, suffering, and the sensory-motor effects of their deformities and of the treatment they undergo, and, finally, from their variable readiness to submit to and to pay for treatment with their time and with their money. Any therapeutic technique must take into account these realities which sometimes oblige us to modify an ideal technique so that it will fit the specialized needs of a patient, an accommodation that can be defined as "therapeutic realism". When we ignore this reality, we risk the paradox of providing patients with technically ideal results that they find unsatisfactory or discover that what we thought was a technically mediocre outcome has delighted our patient: ultimately, it is the patient's judgment that determines the "therapeutic result" and is, in effect, the Final Evaluation of the technical result.

    Cleft lip and cleft palate, which can also occur together as cleft lip and palate, are frequent and debilitating congenital malformations, with complex geneses that have both genetic and environmental factors implicated. Mutations in the genes encoding the p53 homolog p63 and interferon regulatory factor 6 (IRF6) are major causes of cleft lip and cleft palate, but the molecular and cellular mechanisms underlying this have not been clear. However, in this issue of the JCI, Thomason et al. and Moretti et al. independently show that p63 and IRF6 operate within a regulatory loop to coordinate epithelial proliferation and differentiation during normal palate development. Disruption of this loop as a result of mutations in p63 or IRF6 causes congenital clefting.

METHODS: The subject were 50 children (aged 7 to 17) with congenital cleft lip and palate,and 50 normal children as control.Both groups were investigated by Eysenck personality questionnaire EPQ(Junior). RESULTS: According to the general quantitative table of EPQ(Junior),the abnormal cases in cleft group were significantly more than those in control(P<0.005),and also were the abnormal cases in the single quantitative or in the multiple quantitative tables of EPQ(Junior)(P<0.005) respectively. CONCLUSION: The poor personality in children with cleft lip and palate is correlated to the cleft condition.Therefore it is necessary to pay attention to the prevention of poor personality while the cleft lip and palate is treated.

    OBJECTIVE. To investigate cleft disordered tissue in children with cleft palate and cleft lip with or without alveolar clefting for detection of local tissue growth factors and growth factor receptors and compare findings. Design. Morphological analysis of human tissue. Patients. Three groups were studied: 14 patients with cleft palate at the age from eight months to 18 years and two months, 12 patients with cleft lip with or without alveolar clefting in the age from four months to 15 years and four months and 11 control patients. RESULTS. In general, cleft palate disordered tissue showed more prominent expression of BMP2/4 (z=3.574; p=0.0004) and TGFβ (z=2.127; p=0.033), while expression of TGFBR3 significantly higher was only in connective tissue (z=3.822; p=0.0001). Cleft lip affected tissue showed significantly pronounced expression of FGFR1 in general as well as separately in epithelium. CONCLUSIONS. The marked and statistically significant expression of BMP 2/4 in cleft palate disordered soft tissue probably is delayed, but still proliferation and differentiation as well as tissue, especially, bone remodeling contributing signal. Cleft palate affected tissue show more prominent expression of TGFβ, still the weak regional expression of TGFβ type III receptors prove the disordered tissue growth and changed TGFβ signalling pathway in postnatal pathogenesis. In general, expression of TGFβ, BMP 2/4 and FGFR1 is significantly different, giving evidence to the involvement of these mentioned factors in the cleft severity morphopathogenesis.

    Cleft lip/palate comprises a large fraction of all human birth defects, and is notable for its significant lifelong morbidity and complex etiology. Several studies have shown that genetic factors appear to play a significant role in the etiology of cleft lip/palate. Human chromosomal region 9q21 has been suggested in previous reports to contain putative cleft loci. Moreover, a specific region (9q22.3-34.1) was suggested to present a ∼45% probability of harboring a cleft susceptibility gene. Fine mapping of fifty SNPs across the 9q22.3-34.11 region was performed to test for association with cleft lip/palate in families from United States, Spain, Turkey, Guatemala, and China. We performed family-based analysis and found evidence of association of cleft lip/palate with STOM (rs306796) in Guatemalan families (P=0.004) and in all multiplex families pooled together (P=0.002). This same SNP also showed borderline association in the US families (P=0.04). Under a nominal value of 0.05, other SNPs also showed association with cleft lip/palate and cleft subgroups. SNPs in STOM and PTCH genes and nearby FOXE1 were further associated with cleft phenotypes in Guatemalan and Chinese families. Gene prioritization analysis revealed PTCH and STOM ranking among the top fourteen candidates for cleft lip/palate among 339 genes present in the region. Our results support the hypothesis that the 9q22.32-34.1 region harbors cleft susceptibility genes. Additional studies with other populations should focus on these loci to further investigate the participation of these genes in human clefting. PMID:20583170

    It is difficult today to find older patients without their cleft palate prosthetically rehabilitated. This case report presents the rehabilitation by conventional dental prostheses of a cleft palate patient who had no prior treatment. A 52-year-old male presented himself to have his fissured palate obturated and occlusion restored. He reported difficulties in swallowing food and liquids, along with a severe speech disability. The patient's medical history revealed diabetes mellitus type II, hypertension, low vision due to macular atrophic lesions, and xerostomia. The upper and lower arches were completely and partially edentulous, respectively. The treatment plan involved a conventional denture to be placed in the upper arch, and a removable partial denture to be placed in the lower arch.

    To look for a persistent maternal effect of CL(P) and CP, 8,000 pedigrees were screened for half sibships, and data were pooled from 16 investigators. After excluding known genetic or cytogenetic diagnoses from the probands with facial clefts, a recurrence risk of .011 was obtained for CL(P) based upon 342 maternal half sibs. This was nearly identical to the risk of .014 based upon 210 paternal half sibs. CP proband frequencies of .004 for maternal half sibs and .009 for the paternal counterparts were also found. The lack of significant maternal effects in this data supports previously reported data from twin studies and from interracial crosses from Hawaii. The lack of maternal effect in human CL(P) and CP is in contrast to genetic data on clefting in mice. PMID:930925

    Semaphorin signaling plays integral roles in multiple developmental processes. Branching morphogenesis is one such role that has not been thoroughly explored. Here, we show in mice that functional blockage of neuropilin 1 (Npn1) inhibits cleft formation in the developing submandibular gland (SMG) cultured ex vivo. This Npn1-dependent morphogenesis is mediated by Sema3A and Sema3C in an additive manner, and can be abolished by decreasing the expression of plexin A2 or plexin D1. VEGF, another known Npn1 ligand, has no apparent effects on SMG development. FGF signaling, which also mediates SMG branching morphogenesis, acts in parallel with semaphorin signaling. Finally, in contrast to the effect of FGF signaling, we find that semaphorins do not stimulate the proliferation of SMG epithelial cells. Instead, the semaphorin signals act locally on the epithelial cells to facilitate SMG cleft formation.

    Orthognathic surgery and distraction osteogenesis play a prime role in the correction of maxillary hypoplasia in patients with cleft lip and palate (CLP). Advancement of the anterior maxilla alone without interfering with the velopharyngeal sphincter may be advantageous in cleft patients, who more commonly have speech deficits and dental crowding. We present a case series of anterior maxillary segmental distraction for maxillary hypoplasia in 5 CLP patients with a one-year follow-up. A custom-made tooth-borne distraction device with a hyrax screw positioned anteroposteriorly was used. The evaluation comprised of hard and soft tissue analysis and speech assessment. A stable occlusion with positive overjet and correction of dental-crowding without extraction was achieved at one year post-distraction. Facial profile and lip support improved. There was no deterioration in speech. PMID:23984033

  3. Bridging the synaptic cleft: lessons from orphan glutamate receptors.

    For neurons to communicate, signals must cross the cell-to-cell distance at their points of contact. At the predominant cell-cell contact in the central nervous system, the chemical synapse, the synaptic cleft spans roughly 20 nanometers. To signal across this distance, the presynaptic neuron secretes a diffusible neurotransmitter, which is detected by receptors on the postsynaptic neuron. Although this signaling mechanism has become common knowledge, it remains unclear how synapses are maintained when they are not in immediate use. New evidence reveals how Nature solved this problem at a particular type of synapse in the cerebellum: Three old acquaintances bridge the cleft. The ionotropic glutamate receptor GluD2 constitutes the postsynaptic anchor that indirectly interacts with the presynaptic anchor neurexin through a presynaptically secreted soluble factor, a member of the C1q protein family named Cbln1. This trio collaborates to align pre- and postsynaptic sides.

    Objective To compare academic achievement in children with oral-facial clefts (OFC) with their unaffected siblings. Methods 256 children with OFC were identified from the Iowa Registry for Congenital and Inherited Disorders, and 387 unaffected siblings were identified from birth certificates. These data were linked to Iowa Testing Programs achievement data. We compared academic achievement in children with OFC with their unaffected siblings using linear regression models, adjusted for potential confounders. In post hoc analyses, we explored modifiers of siblings’ academic performance. Results Achievement scores were similar between children with OFC and their siblings. Children with cleft palate only were significantly more likely to use special education than their unaffected siblings. Siblings’ academic achievement was inversely related to distance in birth order and age from the affected child. Conclusion Children with OFC and their siblings received similar achievement scores. Younger siblings, in particular, may share a vulnerability to poor academic outcomes. PMID:24993102

    Cleft palate repair mandates use of a mouth gag and Dingmans moth gag is the most commonly used for the same; but the use of Dingmans mouth gag may have the demerit of the suture getting tethered at various places of the instrument during cleft palate closure particularly in the hands of the beginner surgeon. This article discusses about a simple technique of using a rubber dam sheet to cover the frame of the mouth gag. The technique discussed in this article is simple, cost effective method to overcome the potential disadvantage of suture adherence during repair of palatal tissue. The technique also has the potential to reduce the total operative time which needs a further study to validate the same.

    Aspiration is the passage of food content and endogenous secretions into the airway. Anatomical, neuromuscular or functional anomalies are among the major causes. The laryngeal cleft is a rare congenital anomaly that should be considered in the differential diagnosis of aspiration syndrome in neonates and infants. The main symptoms are stridor, recurrent respiratory infections and cyanotic crisis, cough and choking during feeding. The diagnosis is confirmed by endoscopic examination. The therapeutic behaviour will depend on the extent of the cleft, among other factors. We describe the clinical manifestations, diagnostic methods and treatment of an infant with this disease, and we emphasize the need for recognition of swallowing disorders in children in order to establish an accurate diagnosis and appropriate treatment to prevent and avoid malnutrition as well as a severe and potentially irreversible lung compromise.

    A combination is made of observations from the Millstone Hill radar (MHR) and the Defense Meteorological Satellite Program's F7 spacecraft of the dayside features on the ionospheric cleft/cusp during the magnetic storm of February 8-9, 1986; the MHR was in the dayside. Attention is given to the two sets of observations for the prenoon sector in order to ascertain the low-altitude signatures of plasma regions in the vicinity of the cusp. Boundary plasma sheet particles coincided with a narrow region of magnetic field-aligned currents, as well as with antisunward convection flows at the equatorward edge of the cleft. Particle and field signatures are identified for the plasma sheet, plasma sheet boundary layer, low latitude boundary layer, cusp, and mantle, at unusually low magnetic latitude during the event.

    Dealing with this type of malformation, the orthodontist is confronted with a three-level problem: inter-personal, social, and technical. Because families consider the birth of a cleft palate child to be a disaster, orthodontists who undertake their treatment should understand the genesis of the turbulence that families will have to endure. Most parents learn to deal with these difficulties, but the affected children are going to have to submit to the stares of those they encounter. Adolescence is a critical period for them and it is also the time when they will visit their orthodontist most frequently. Problems that accompany treatment of these patients are numerous and the treating orthodontists must point them out and explain them tactfully. The treating team must also establish a therapeutic alliance to envelop the cleft palate patients, ensuring maintenance of expert cooperation between specialists responsible for different aspects of their treatment.

    Summary Continuous shape change is represented as curves in the shape space. A method for checking the closeness of these curves to a geodesic is presented. Three large databases of short human motions are considered and shown to be well approximated by geodesics. The motions are thus approximated by two shapes on the geodesic and the rate of progress along the path. An analysis of facial motion data taken from a study of subjects with cleft lip or cleft palate is presented that allows the motion to be considered independently from the static shape. Inferential methods for assessing the change in motion are presented. The construction of predicted animated motions is discussed. PMID:22639469

    We present a unique and challenging case of a remnant foreign body that presented to us in a child disguised as a strongly suspected congenital branchial cleft anomaly. This case entailed oropharyngeal trauma, with a delayed presentation as a retroauricular cyst accompanied by otorrhea that mimicked the classic presentation of an infected first branchial cleft anomaly. During surgical excision of the presumed branchial anomaly, a large wooden stick was found in the tract. The diagnostic and therapeutic obstacles in the management of such cases are highlighted. In addition to exploring the existing literature, we retrospectively analyzed a plausible explanation of the findings of this case.

    Vocational and economic aspects of social functioning were evaluated for 196 adult cleft subjects, their 190 siblings and 209 random controls. Results indicated that cleft adults functioned within normal limits with regard to employment. However, levels of income were substantively lower than control groups. Cleft subjects compare favorably with their siblings and random controls in occupational mobility over the levels attained by their fathers. It would appear that cleft subjects experience some limitation in their ability to secure vocational and economic rewards from society.

    2015-03-23

    Surgical correction is central to current team-approached cleft treatment. Cleft surgeons are always concerned about the impact of their surgical maneuver on the growth of the maxilla. Hypoplastic maxilla, concaved mid-face and deformed dental arch have constantly been reported after cleft treatments. It is very hard to completely circumvent these postoperative complications by current surgical protocols. In this paper, we discussed the factors that inhibit the maxillofacial growth on cleft patients. These factors included pre-surgical intervention, the timing of cleft palate and alveolae repair, surgical design and treatment protocol. Also, we made a review about the influence on the maxillary growth in un-operated cleft patients. On the basis of previous researches, we can conclude that most of scholars express identity of views in these aspects: early palatoplasty lead to maxilla growth inhibition in all dimensions; secondary alveolar bone graft had no influence on maxilla sagittal growth; cleft lip repair inhibited maxilla sagittal length in patients with cleft lip and palate; Veau's pushback palatoplasty and Langenbeck's palatoplasty with relaxing incisions were most detrimental to growth; Furlow palatoplasty showed little detrimental effect on maxilla growth; timing of hard palate closure, instead of the sequence of hard or soft palate repair, determined the postoperative growth. Still, scholars hold controversial viewpoints in some issues, for example, un-operated clefts have normal growth potential or not, pre-surgical intervention and pharyngoplasty inhibited maxillofacial growth or not.

    Objectives: To present descriptive epidemiology of Orofacial Clefts and to determine the association of syndromic forms with antenatal high-risk conditions, preterm birth, and comorbidities among nested-series of cases. Methods: A study of nested-series of cases was conducted. Frequencies of cleft type, associated congenital anomalies, syndromic, non-syndromic and multiple malformation forms, and distribution of Orofacial Clefts according to sex and affected-side were determined. Odds ratios were calculated as measures of association between syndromic forms and antenatal high-risk conditions, preterm birth and comorbidities. A total of three hundred and eleven patients with Orofacial Clefts were assessed in a 12-month period. Results: The most frequent type of Orofacial Clefts was cleft lip and palate, this type of cleft was more frequent in males, whereas cleft palate occurred more often in females. The most common cases occurred as non-syndromic forms. Aarskog-Scott syndrome showed the highest frequency amongst syndromic forms. Hypertensive disorders in pregnancy, developmental dysplasia of the hip, central nervous diseases and respiratory failure showed significant statistical associations (p <0.05) with syndromic forms. Conclusions: These data provide an epidemiological reference of Orofacial Clefts in Colombia. Novel associations between syndromic forms and clinical variables are determined. In order to investigate causality relationships between these variables further studies must be carried out. PMID:26848196

    The embryologic fusion planes might be related with the sites of onset of basal cell carcinoma (BCC), thus supporting an embryologic role for its pathogenesis. A study involving 495 patients with 627 BCCs of the head and neck was carried out over a period of 5 years by correlating the distribution of all BCCs with the sites of congenital clefts of the head and neck using (1) the original anatomic diagram of the Tessier classification of craniofacial clefts, (2) the anatomic diagram by Moore et al featuring the paths of the "hairline indicators" of craniofacial clefts that represent the cranial extensions of the Tessier classification, and (3) an anatomical diagram featuring the sites of congenital clefts of the neck. The proportion of BCCs localized within a cleft site was significantly higher than those in the noncleft sites. The age of patients with BCCs localized within the Tessier cleft number 3 was the lowest among all cleft regions. A topographic correspondence between the sites of BCCs and the sites of congenital clefts was demonstrated in the head and neck. This evidence would support the hypothesis of an embryologic role for the pathogenesis of BCC. The existence of clusters of embryological stem cells in the sites of fusion and/or merging of embryonic processes might therefore be proposed. There may be special biology/physiology along these cleft lines that predispose BCC formation.

    Background Over the years, great efforts have been made to record the frequency of orofacial clefts in different populations. However, very few studies were able to account for the etiological and phenotypic heterogeneity of these conditions. Thus, data of cases with syndromic orofacial clefts from large population-based studies are infrequent. Methods Clinically recognized and notified syndromes and associations including cleft lip with or without cleft palate and other congenital anomalies were selected from the Hungarian Congenital Abnormality Registry (HCAR) between 1973 and 1982 and prevalence rates were calculated. Results Of 3,110 cases reported as having orofacial clefts, 653 had multiple congenital abnormalities. Of these, 60 (9.2%) had a known etiology (monogenic: 25 or 3.8%, chromosomal: 31 or 4.7%, teratogenic: 4 or 0.6%). Seventy-three subjects (11.2%) had schisis in addition to the oral cleft. Skeletal anomalies were the most common malformations among cases with cleft lip with/without cleft palate (CL/P) and cleft palate (CP). Disorders of the central nervous system and cardiovascular malformations were also frequently associated. Conclusion Surveillance systems, such as the HCAR, provide useful information about prevalence rates of congenital anomalies in a population. However, in a field where new syndromes are being discovered and classifications regularly updated, these rates should only be accepted as provisional. PMID:15985166

    Clefting of the lip and palate is the most frequent craniofacial malformation that occurs in newborn babies. The greatest immediate challenge facing a neonate with a cleft is to take nourishment. In developing countries and particularly in rural areas, palatal obturators and other aids that can assist in feeding are not easily available or accessible. The aim of this study was to develop, evaluate and report on the cleft seal, a simple and inexpensive device that is used with a feeding bottle to promote nourishment of a neonate with a cleft palate. The cleft seal is made of either silicone or thermoform plastic and consists of a spoon-like projection attached to a circular washer. The latter fits snugly between the teat base and collar of the feeding bottle, while the spoon-like projection forms a canopy over the teat and separates the nasal cavity from the mouth during feeding. Closure of the cleft emulates the natural feeding process and favours normal orofacial development. Results from this study indicate that there is an increase in nutritional intake over a shorter feeding time when using the cleft seal. Parents also report an absence of nasal regurgitation. The greatest advantage of the cleft seal lies in its negligible cost and ease of use, which can enable distribution and application in remote neonatal centres, where nursing and parental care givers are often at a loss as to what to do when faced with a newborn with a cleft palate.

    In infants with cleft lip and palate, failure to thrive (FTT) condition has largely been attributed to early feeding difficulties. Presurgical Nasoalveolar Molding (PNAM) forms an integral part of treatment modality for cleft infants in such conditions, by providing a myriad of benefits.It balances several aspects of treatment such as growth, aesthetics and function in cleft infants and also provides psychological reassurance to the parents. This clinical report describes the presurgical management of an infant with complete unilateral cleft lip and palate who was in failure to thrive condition.

    To determine the views of Clinical Directors working in the United Kingdom (U.K.) Cleft Service with regard to centralisation, commissioning and impact on cleft service provision. In-depth qualitative interviews were conducted with 11 Clinical Directors representing regional cleft services. Interviews were transcribed verbatim, a coding frame was developed by two researchers and transcripts were coded using a thematic, 'interpretive' approach. Clinical Directors perceived the commissioning of cleft services in the U.K. to be dependent upon historical agreements and individual negotiation despite service centralisation. Furthermore, Clinical Directors perceived unfairness in the commissioning and funding of cleft services and reported inconsistencies in funding models and service costs that have implications for delivering an equitable cleft service with an effective Multidisciplinary Team. National Health Service (NHS) commissioning bodies can learn lessons from the centralisation of cleft care. Clinical Directors' accounts of their relationships with specialist commissioning bodies and their perspectives of funding cleft services may serve to increase parity and improve the commissioning of cleft services in the U.K.

    To explore a new method of repair of alveolar cleft by trans-sutural distraction osteogenesis. Nine 8-week-old mongrel dogs were assigned randomly to two groups with three in the control group and six in the experimental group. First, an alveolar cleft model was created surgically in all animals. After 2 weeks, a U-shaped distractor, made of nickel-titanium (NiTi) shape memory alloy wire with 200 g tensile force, was inserted into the premaxilla of the experimental dogs to distract the mid-premaxillary suture for 3 weeks. Periosteoplasty of the alveolar cleft was performed when the premaxilla at the side of cleft approached the maxilla at the same side. The distractor was removed 2 weeks post periosteoplasty. The results were evaluated clinically, radiographically, and morphologically. The cleft model was stable and similar to the human alveolar cleft. No spontaneous bone union occurred in the control. In experimental dogs, the premaxilla was moved slowly toward the maxilla, and the cleft became gradually narrower and closed in the third week. Radiographically, the distracted mid-premaxillary suture showed a gradually widened triangle, with the tip of the triangle pointed posteriorly. The density of the distracted triangle suture was increased gradually. The alveolar cleft was completely bony 3 months post periosteoplasty. The morphology of the mid-premaxillary suture was also restored. The alveolar cleft could be repaired by the technique of mid-premaxillary suture distraction using the elastic device of NiTi shape memory alloy.

    2011-05-01

    To assess the skeletal and dental effects of rapid maxillary expansion in a patient with unilateral cleft deformity of secondary palate and alveolus using the finite element method. A patient-specific composite skull model was developed from a patient computed tomographic scan and a surface scan of the patient's maxillary cast using MIMICS imaging analysis software. For volumetric meshing and the finite element analysis, Abaqus (6.7) was used. The typical wedge-shaped opening that occurs after RME, seen in non-cleft patients, is not seen in cleft patients. A clockwise rotation of the maxilla as a result of maxillary expansion was evident. The areas of maximum stress were the intact primary palate region, inferior orbital foramen of the non-cleft and the cleft sides, and the zygomatic buttress of the cleft side. During expansion, the intact primary palate showed high stress and acted as a region of major resistance, followed by the zygomatic buttress on the cleft side. Clinicians should consider a need for customization of expansion therapy for cleft patients depending on the patient's age, the type of cleft present (primary or secondary palate), and the desired area of expansion (anterior or posterior).

    In Latin American countries, studies on the incidence of cleft lip and palate are not widely available. A 10-year retrospective study was carried out to determine the incidence of cleft lip and palate at the Autonomous University of Nuevo Leon's University Hospital. The study included data from patients who attended the plastic surgery outpatient clinic from January 1990 to December 1999. The author reviewed 10,843 files from which 376 patients were selected to identify the following variables: time of the year in which the first consultation took place, gender, birthplace, type of cleft, age of both parents, and medications taken during pregnancy. The highest incidence was found in patients aged 1 to 6 months. Ninety-four patients had a primary palate cleft; 76 had a secondary palate cleft; and 206 had primary and secondary palate clefts. The gender distribution of the 206 patients with primary and secondary clefts was 127 boys and 79 girls. The mean parent age was 29.5 years (father) and 25.7 years (mother). The incidence of cleft lip and palate in the cited hospital was 1.1:1000 births. Clefts of the left side occurred more often than of the right. Boys were affected more commonly than girls.

    A lot of children with cleft lip and palate are not operated in the developing world, due to a lack of surgeons, hospitals, or simply because the condition is not considered as a priority. Charity missions give the opportunity to repair these malformations. Non-operated cleft lip and palate are the first problem, but our surgery may cause growth disturbances and sometimes a second operation is needed, more difficult than the first one in mission conditions. Repairing a cleft palate needs to be adapted to the type of cleft but also to the age of the child, a velopalatine pharyngoplasty can be performed in some cases.

    Abstract Background: This study aimed to obtain epidemiological data of birth incidences of cleft lips and/or cleft palates (CLP) in the Thai population with associated risk factors. Methods: The data were collected for a period of 12 months between 2003 and 2004 for infants’ deliveries with CLP and associated risk factors in all hospitals of 6 provinces from 4 regions of Thailand. The birth incidence, related factors with cleft birth, and linkage with geographical area were analyzed by the geographic information system. Results: Phitsanulok, Saraburi, and Khon Kaen had higher birth incidences for CLP of 2.01, 1.69, and 1.66 per 1000 live births, respectively, and the overall birth incidence was 1.51 per 1000 live births. There were a total of 112 cleft births (61 males and 51 females) with 43 cleft lips, 18 cleft palates, and 51 cleft lips + cleft palates. The northeast region had infants with different gestational ages at birth and mothers with higher intakes of vitamins and a use of vitamin A supplement or retinoic acid than others. A use of folic acid supplement was low in all 4 regions. Conclusions: The varied incidence of CLP may reflect the incomplete accuracy of case ascertainment. A number of challenges were addressed. The geographic information system was helpful for more background investigation and planning of cleft care management. Our study enables future studies of etiological factors and future birth registries. PMID:26894008

    Objective This exploratory research sought to identify movement related soft tissue changes in the midfacial region in individuals with a cleft lip/palate and unaffected relatives compared to controls. The cleft phenotype (clinically identified cleft or occult Orbicularis oris muscle defect) was hypothesized to affect movement in the midfacial region, leading to furrowing and dimpling during speech. Design Changes in the appearance of skin in the midfacial region, including a newly identified feature, nasolabial fold discontinuity (NLF discontinuity), were described and compared across groups. Participants Individuals with cleft lip (n= 42) and unaffected relatives of persons with a cleft (n = 57) were compared to healthy controls (n= 41). Results NLF discontinuities were observed more frequently in individuals with a cleft phenotype (overt cleft or OOM defect) than in those with no underlying muscular defect (Fisher Exact test, p = .014). Conclusion Results suggest that movement of the muscles of facial expression is moderated at least in part by underlying cleft risk factors, indicating certain facial movements as candidate physical marker for extension of the cleft phenotype.

    Children with cleft lip and palate require interdisciplinary team care from infancy through adolescence. An understanding of developmental stages allows the cleft palate team to adapt and integrate its services into the rapidly changing life of the child. This article discusses the maturational, developmental stages of childhood and the services the child with cleft lip and palate and the child's family deserve through each stage. Health care providers in all settings may continue to provide appropriate care for all patients with cleft lip and palate, despite the challenges of a changing health care environment, by emphasizing the needs of the child in all developmental stages.

    Isis 1 satellite observations of the cleft position during magnetospheric substorms show that the cleft shifts equatorward as the interplanetary B sub z component turns southward and substorm activity increases and that it shifts back toward higher latitudes as substorm activity subsides and B sub z returns northward. Also, unusually low latitudes for the cleft (less than 70 deg invariant latitude) were found during geomagnetic storms with significant Dst values and large negative B sub z values. Significant shifts occur in the cleft location with no accompanying effect seen in the AE index; however, B sub z is observed to be southward during these periods.

    Orofacial clefts are the most prevalent birth defects that affect craniofacial structures and implicate genetic and environmental factors in their aetiology. Maternal metabolic state and nutrition have been related to these and other structural malformations, and studies of maternal obesity before pregnancy have shown controversial results about its association with the risk of orofacial clefts in their offspring. Our aim was to assess the combined effect of several single studies of maternal obesity on the risk of orofacial clefts using meta-analysis. We searched for these reports in the PubMed database, and selected 8 studies that met our criteria for eligibility. As a result of this analysis, and using maternal normal weight as a reference, we found that maternal obesity does increase the risk of orofacial clefts in their offspring (OR 1.18, 95% CI 1.11 to 1.26). When these clefts are considered separately, maternal obesity is associated with cleft lip with or without cleft palate (OR 1.13, 95% CI 1.04 to 1.23), and with cleft palate alone (OR 1.22, 95% CI 1.09 to 1.35). Our results support the relation between maternal obesity and orofacial clefts, and confirm two previous meta-analyses that considered fewer studies. However, the molecular mechanisms underlying this statistical evidence have not been fully elucidated.

    Abstract Oblique facial clefts are rare congenital anomalies that can present alone or in association with other craniofacial anomalies. A high degree of clefting in the embryo may lead to hyperdontia secondary to dichotomy of the dental lamina. Multiple facial clefts with hyperdontia are clinically challenging and demand comprehensive rehabilitation. This article reports a case of multiple oblique facial clefts of variable severity with multiple supernumerary teeth in a 12-year-old boy. The varied clinical presentation along with the rarity of the occurrence mandate documentation. PMID:24294408

    Isis 1 satellite observations of the cleft position during magnetospheric substorms show that the cleft shifts equatorward as the interplanetary B sub z component turns southward and substorm activity increases and that it shifts back toward higher latitudes as substorm activity subsides and B sub z returns northward. Also, unusually low latitudes for the cleft (less than 70 deg invariant latitude) were found during geomagnetic storms with significant Dst values and large negative B sub z values. Significant shifts occur in the cleft location with no accompanying effect seen in the AE index; however, B sub z is observed to be southward during these periods.

    Rapp-Hodgkin syndrome (RHS) is a rare type of autosomal dominant disorder characterized by association of ectodermal dysplasia (ED) with cleft lip/palate. The main features include dry, brittle hair with alopecia in adulthood, dental anomalies (hypodontia, microdontia with delayed eruption, fissured tongue, and retruded maxilla), hypohidrosis, dysplastic nails, and clefting. Palmar-plantar keratoderma is seen frequently. RHS has signs and symptoms that overlap considerably with those of ankyloblepharon-ED-clefting syndrome and ectrodactyly-ED-clefting syndrome. This manuscript discusses a case of RHS, one of the four members in three generations who had ED with variable degree of involvement of hair, teeth, nail, and sweat glands.

    This study evaluates the feasibility of endoscope-assisted second branchial cleft cyst resection via retroauricular approach by comparing it with conventional cervical incision for removal of second branchial cleft cyst. From January 2009 to December 2010, 25 patients were randomly assigned to the endoscope-assisted surgery group (13 patients) or the conventional surgery group (12 patients). The clinical characteristics of patients, operation time, operative bleeding volume, postoperative complications, and subjective satisfaction with incision scar checked by visual analog scale were compared between the groups, retrospectively. All 13 second branchial cleft cyst resections were successfully performed endoscopically, and the wounds healed uneventfully. Endoscope-assisted surgery lasted 54.6 ± 6.3 min, and conventional surgery lasted 49.6 ± 6.9 min (P = 0.069). Degree of bleeding volume did not differ between the groups (P = 0.624). Mean patient satisfaction score was 9.2 ± 0.6 in the endoscope-assisted surgery group and 6.2 ± 0.8 in the controls (P < 0.001). All 13 patients in the endoscope-assisted surgery group were satisfied with their cosmetic results. One case showed temporary numbness around the earlobe that recovered within 1 month after surgery. No marginal nerve palsy occurred. No complications such as bleeding, salivary fistula, or paresis of the marginal mandibular branch occurred. All 25 patients were disease free with follow-up of 6-24 months (median 16 months). Endoscope-assisted second branchial cleft cyst resection via retroauricular approach is a feasible technique. This procedure may serve as an alternative approach that allows an invisible incision and better cosmetic results.

    Orofacial clefts are a common problem that can lead to significant healthcare use and costs, as well as suffering on the part of the affected individuals and families. There are several theories explaining their origin, but some of the findings are inconsistent. The most accepted theories involve a major genetic basis that could be modified by the presence of external agents. Understanding the underlying causes could help to prevent its occurrence, an area in which the family physician can play an important role.

    In order to evaluate the pathogenesis of cleft-lip in relation to both the anatomical and structural anomalies of the mesenchymal tissues, the authors concluded that the presence of structural anomalies in the examined tissues could not explain the malformation, but might be a consequence of it. Delayed muscular development, asymmetrical distribution of the muscular fibres and their anomalous insertion suggest that the anatomical/functional loss clinically detectable in the orbicular muscle could be the result of a perinatal dysmorphological process rather than of a simple mesenchymal hypoplasia. Schendel et al. suggested that a metabolic defect in the mitochondrial function could cause a deficiency in cell migration and proliferation responsible for the malformation in question. To establish whether the pathogenesis of the cleft-lip is associated with an alteration in mitochondrial functionality, eight patients affected by unilateral cleft-lip were subjected to a biopsy of the orbicular muscle during the course of reparative surgery. The results obtained showed: 1) a great variation in the size of muscle fibres; 2) the absence of ragged red fibres; 3) a normal oxidative function in the muscle fibres examined; 4) the absence of typologically significant groupings positive for myofibral ATPases. Furthermore, the morphology of the mitochondria was preserved in all cases and neither inclusions nor morphological or volumetric changes were detected. This preliminary data did not confirm the constant presence of mitochondrial pathology responsible for the malformation in question. In our opinion, the growth deficiency of the maxillary segment could be ascribed to the cicatrization of the surgical repair of the cleft-lip.

  16. Epidemiology, Etiology, and Treatment of Isolated Cleft Palate

    2016-01-01

    Isolated cleft palate (CPO) is the rarest form of oral clefting. The incidence of CPO varies substantially by geography from 1.3 to 25.3 per 10,000 live births, with the highest rates in British Columbia, Canada and the lowest rates in Nigeria, Africa. Stratified by ethnicity/race, the highest rates of CPO are observed in non-Hispanic Whites and the lowest in Africans; nevertheless, rates of CPO are consistently higher in females compared to males. Approximately fifty percent of cases born with cleft palate occur as part of a known genetic syndrome or with another malformation (e.g., congenital heart defects) and the other half occur as solitary defects, referred to often as non-syndromic clefts. The etiology of CPO is multifactorial involving genetic and environmental risk factors. Several animal models have yielded insight into the molecular pathways responsible for proper closure of the palate, including the BMP, TGF-β, and SHH signaling pathways. In terms of environmental exposures, only maternal tobacco smoke has been found to be strongly associated with CPO. Some studies have suggested that maternal glucocorticoid exposure may also be important. Clearly, there is a need for larger epidemiologic studies to further investigate both genetic and environmental risk factors and gene-environment interactions. In terms of treatment, there is a need for long-term comprehensive care including surgical, dental and speech pathology. Overall, five main themes emerge as critical in advancing research: (1) monitoring of the occurrence of CPO (capacity building); (2) detailed phenotyping of the severity (biology); (3) understanding of the genetic and environmental risk factors (primary prevention); (4) access to early detection and multidisciplinary treatment (clinical services); and (5) understanding predictors of recurrence and possible interventions among families with a child with CPO (secondary prevention).

Rarely, RCC can present with chemical meningitis, sellar abscess, lymphocytic hypophysitis, or intracystic hemorrhage. We describe an unusual presentation of RCC in which the patient presented with a clinical picture of chemical meningitis consisting of meningeal irritation, inflammatory cerebrospinal fluid profile, and enhancing pituitary and hypothalamic lesions, in addition to involvement of the optic tracts and optic nerve.

    Nonsyndromic orofacial clefts (OFCs) are a heterogeneous group of common craniofacial birth defects with complex etiologies that include genetic and environmental risk factors. OFCs are commonly categorized as cleft lip with or without cleft palate (CL/P) and cleft palate alone (CP), which have historically been analyzed as distinct entities. Genes for both CL/P and CP have been identified via multiple genome-wide linkage and association studies (GWAS); however, altogether, known variants account for a minority of the estimated heritability in risk to these craniofacial birth defects. We performed genome-wide meta-analyses of CL/P, CP, and all OFCs across two large, multiethnic studies. We then performed population-specific meta-analyses in sub-samples of Asian and European ancestry. In addition to observing associations with known variants, we identified a novel genome-wide significant association between SNPs located in an intronic TP63 enhancer and CL/P (p = 1.16 × 10(-8)). Several novel loci with compelling candidate genes approached genome-wide significance on 4q21.1 (SHROOM3), 12q13.13 (KRT18), and 8p21 (NRG1). In the analysis of all OFCs combined, SNPs near FOXE1 reached genome-wide significance (p = 1.33 × 10(-9)). Our results support the highly heterogeneous nature of OFCs and illustrate the utility of meta-analysis for discovering new genetic risk factors.

    SUMMARY The cleft is an integral part of synapses, yet its macromolecular organization remains unclear. We here show that the cleft of excitatory synapses exhibits a distinct density profile as measured by cryo-electron tomography (cryo-ET). Aiming for molecular insights, we analyzed the synapse-organizing proteins SynCAM 1 and EphB2. Cryo-ET of SynCAM 1 knock-out and overexpressor synapses showed that this immunoglobulin protein shapes the cleft’s edge. In agreement, SynCAM 1 delineates the postsynaptic perimeter as determined by immuno-electron microscopy (EM) and superresolution imaging. In contrast, the EphB2 receptor tyrosine kinase is enriched deeper within the postsynaptic area. Unexpectedly, SynCAM 1 can form ensembles proximal to postsynaptic densities, and synapses containing these ensembles were larger. Postsynaptic SynCAM 1 surface puncta were not static but became enlarged after a long-term depression paradigm. These results support that the synaptic cleft is organized on a nanoscale into sub-compartments marked by distinct trans-synaptic complexes. PMID:26687224

    To describe the clinical findings, diagnosis, and treatment of an incomplete cleft of the 5th-8th sternebra and a cranioventral abdominal wall hernia in a 2 month old Ragdoll kitten and to evaluate the short- and long-term outcome. Clinical report. Ragdoll cat (n = 1), 2 months old. Sternal cleft was confirmed by thoracic radiographs. Computed tomography (CT) was used to plan an optimal surgical approach. A ventral median incision was made, starting at the 3rd sternebra and extended into the abdomen. Ostectomy of the proximal part of the 5th left sternebra was performed. Lateral periosteal flaps were created, unfolded, and absorbable monofilament sutures preplaced to facilitate closure and the repair was reinforced by 2 peristernal sutures. A bone graft was applied, and the free margin of the omentum was sutured to the cranial aspect of the wound. No major complications occurred. At 3 weeks, CT scan confirmed approximation of the hemisternebrae and at 10 months, complete fusion of the hemisternebrae had not occurred, but a strong connection of the sternal bars was present. Sternal cleft is a rare congenital abnormality that can be corrected surgically with favorable outcome. © Copyright 2014 by The American College of Veterinary Surgeons.

    Objectives : Cleft palate is a common congenital maxillofacial defect. We wish to present the fabrication of a modified feeding plate that will adapt to the changing palatal and velopharyngeal morphology during function. Case Report : A neonate with unilateral cleft lip and palate was referred to our clinic for the fabrication of a feeding plate. Intraoral examination revealed a cleft involving the uvula and the soft palate, with an alveolar defect on the left side. An impression was taken and a dental cast was obtained. A 1-mm Bioplast clear soft plate was pressed on the model. After trimming the edges of the plate, several retentive holes were made for its attachment to the hard plate. With the Bioplast soft plate replaced on the cast, plaster was used to cover parts of the soft plate that were not to come in contact with the hard plate. Biocryl resin was put on the retentive holes and 2-mm Biocryl C Rosa-transparent plate was pressed. The edges of the plate were cut, trimmed, and polished. Conclusion : This modified feeding plate effectively obstructed the soft palate defect. The adaptation of the flexible bulb of the appliance with the soft palate was excellent. Evaluation with nasoendoscopy revealed the synchronized movement of the bulb of the appliance with the soft palate during swallowing. Soft extension of the feeding plate eliminated the risk of irritation, and the baby accepted the appliance easily.

    To achieve an aesthetic lip in cleft lip repair, central fullness and slight eversion of the vermilion are necessary. If only cutaneous anthropometric length is considered, symmetry and good vermilion contour may be obtained, but a seemingly tightness of the lip can occur. To prevent this, it is necessary to obtain sufficient central mucosal tissue of the oral lining.The authors used 2 methods to obtain adequate tissue of the central area of the oral lining. First, the mucosa of the central area of the oral lining was supplemented using a medial mucosal flap, and the amount of superfluous tissue was minimized. Second, a relaxing incision was placed at the oral lining of the lateral flap, which was subsequently centrally advanced.A total of 389 patients with a unilateral cleft lip underwent surgery using these methods and achieved satisfactory results. Occasional cases of lateral vermilion bulging were encountered during long-term follow-up, but these were easily corrected by bulging excision.Consideration of the oral lining is essential in cleft lip repair. The authors were able to reconstruct an aesthetically pleasing lip with central fullness by obtaining an adequate amount of tissue in the central area of oral lining.

    The aim of this study was to assess the 3-dimensional facial surface changes after cleft alveolar bone grafting with digital surface photogrammetry. In a prospective study, 22 patients with cleft lip and palate underwent alveolar bone grafting. Before the procedure and 6 weeks postoperatively and before the continuation of orthodontic treatment, 3-dimensional images were taken with digital surface photogrammetry. Seven standard craniofacial landmarks on the nose and the upper lip were identified. Their spatial change because of bone grafting was assessed. Statistical analysis was performed with analysis of variance and t test. A significant increase in anterior projection on the operative side (P < .05) was found for the labial insertion points of the alar base (subalare). No significant changes were detected for the position of the labial landmarks. Our results show 3-dimensionally that there is a positive influence of the alveolar bone graft on the projection of the alar base on the cleft side.

One of these priorities included postoperative fluid management. The authors' postoperative regimen does not include intravenous fluids unless the child fails to achieve adequate oral intake by the first evening postoperatively. This audit evaluated whether this is appropriate and safe practice.   All patients undergoing cleft-related surgery by a single surgeon in a single center during August 2011 to August 2012 were included. Patient age, weight, and surgery type were recorded together with fluid requirement, length of stay, and any returns to theater or readmissions.   Of the 79 patients included, none required readmission or return to theater, and the mean length of stay was 1.72 days. Nineteen patients (24%) required intravenous fluids, but these tended to be the older children in the group (P value .034). In the youngest patients undergoing primary lip repair, only 1 of 20 required intravenous fluids.   This study demonstrates that, especially in the younger patients, omitting intravenous fluids as a postoperative routine is associated with a shorter length of stay without an increased complication rate. The authors advocate early postoperative feeding and the return to physiological fluid balance.

    Cleft lip and cleft palate are the most common craniofacial anomalies that have an incidence of 0.28 to 3.74 per 1000 live births globally. Due to the great advancements in the field of medical science, these anomalies can today be corrected. However, it cannot be ignored that the parents of these patients may face psychological stress due to the cleft defects in the baby. Also, these conditions may cause financial difficulties to the parents and cause anxiety to the mother about the proper feeding of their infant. Feeding problems can range from excessive air intake to failure to thrive. As the management of such cases is lengthy and includes a multi-disciplinary team approach, it is the role of the Pediatrician/Pedodontist to educate the mother about the proper feeding techniques. In this article, we have reviewed and highlighted the various traditional and advanced devices and techniques which help in the successful management of these individuals. PMID:24478964

    Although a history of cleft palate is the most common cause of velopharyngeal dysfunction (VPD), there are other disorders that can also cause hypernasality and/or nasal emission. These include other structural anomalies of the velopharyngeal valve (velopharyngeal insufficiency), neurophysiological disorders that result in inadequate velopharyngeal movement (velopharyngeal incompetence), and even faulty articulation placement in the pharynx (velopharyngeal mislearning). Unfortunately, individuals with non-cleft causes of hypernasality and/or nasal emission do not typically present at a cleft palate/craniofacial center where there are professionals who specialize in the evaluation and treatment of these disorders. As a result, they are often misdiagnosed and do not receive appropriate treatment. In this review, we present various conditions that can cause hypernasality and/or nasal emission during speech. We discuss appropriate treatment based on the underlying cause of the condition. It is important that pediatric otolaryngologists are able to recognize these disorders so that affected patients are referred to specialists in velopharyngeal dysfunction for treatment.

    Nonsyndromic cleft lip +/- cleft palate (CL/P) is a complex trait of unknown etiology. Most genetic studies of CL/P define affection status in a way that ignores subtle subclinical manifestations, resulting in a potential loss of statistical power. This study investigated 10 candidate genes in 155 individuals from 25 Guatemalan CL/P families. High-resolution ultrasound images of the orbicularis oris (OO) muscle were obtained. CL/P was present in 28 family members; an additional 10 had subcutaneous OO muscle defects. Family-based association studies were performed for both narrow (CL/P only) and broad (CL/P plus OO muscle defects) definitions of affection status. PVRL1 was significantly associated under both definitions (P = 0.04, narrow; P = 0.02, broad). Association with JAG2 improved from P = 0.09 under the narrow definition to P = 0.04 under the broad definition. Broadening the oral-facial cleft phenotype to include subclinical variants may improve power in genetic studies.

    Late primary palatal repair is a common phenomenon, and many patients across the world will be operated on at a far later age than is suggested for normal speech development. Nevertheless, little is known about the speech outcomes after these procedures and conflicting results exist among the few studies performed. In this study, blinded preoperative and postoperative speech recordings from 31 patients operated on at Guwahati Comprehensive Cleft Care Center in Assam, India, older than 7 years were evaluated. Six non-Indian speech and language pathologists evaluated hypernasal resonance and articulation, and 4 local laymen evaluated the speech intelligibility/acceptability of the samples. In 25 of 31 cases, the evaluators could not detect any speech improvement in the postoperative recordings. A clear trend of postoperative improvement was only found in 6 of the 31 patients. Among these 6 patients, lesser clefts were overrepresented. Our findings together with previous studies suggest that late palate repairs have the potential to improve speech, but the probability for improvement and degree of improvement is low, especially in older adolescents and adults with complete clefts.

    Folate deficiency has been associated with numerous diseases and birth defects including orofacial defects. However, whether folate has a role in the face during early orofacial development has been unclear. The present study reveals that pharmacological and antisense oligonucleotide mediated inhibition of DHFR, an integral enzyme in the folate pathway, results in specific changes in the size and shape of the midface and embryonic mouth. Such defects are accompanied by a severe reduction in the muscle and cartilage jaw elements without significant change in neural crest pattern or global levels of methylation. We propose that the orofacial defects associated with DHFR deficient function are the result of decreased cell proliferation and increased cell death via DNA damage. In particular, localized apoptosis may also be depleting the cells of the face that express crucial genes for the differentiation of the jaw structures. Folate supplementation is widely known to reduce human risk for orofacial clefts. In the present study, we show that activating folate metabolism can reduce median oral clefts in the primary palate by increasing cell survival. Moreover, we demonstrate that a minor decrease in DHFR function exacerbates median facial clefts caused by RAR inhibition. This work suggests that folate deficiencies could be a major contributing factor to multifactorial orofacial defects.

    Foster et al. [2002] and others have reported on elevated ionospheric density regions being convected from the subauroral plasmaspheric region toward noon, in association with convection of plasmaspheric tails in the dayside magnetosphere. It has been suggested that these so-called Storm Enhanced Density (SED) regions could serve as ionospheric plasma source populations for cleft ion fountain outflows. To investigate this scenario, we have used our Dynamic Fluid Kinetic (DyFK) model to simulate the entry of a high-density "plasmasphere-like" flux tube entering the cleft region and subjected to an episode of wave-driven transverse ion heating. We find that the O+ ion density at higher altitudes increases and the density at lower altitudes decreases, following this heating episode, indicating increased numbers of O+ ions from the ionospheric source gain sufficient energy to reach higher altitudes after the effects of transverse wave heating. We also find that O+- H+ crossing point in topside ionosphere moves upward as the wave heating continues. Foster, J. C., P. J. Erickson, A. J. Coster, J. Goldstein, and F. J.

    The highest incidence of cleft lip and cleft palate in Thailand occurs in the Northeast Region. Tawanchai Center was set up 10 years ago to be a specialized medical care center where an interdisciplinary team provides care for cleft lip and cleft palate patients. There has never previously been a study about 4-5 year old patients treated and followed-up by the multidisciplinary team. To study the 4-5 year old patient's with cleft lip and cleft palate who received treatment and follow-up in Tawanchai Center, Srinagarind Hospital. This retrospective study was conducted using data from every 4-5 years old cleft lip and cleft palate patients' medical record of the patients who had the continuous multidisciplinary treatment care at Tawanchai Center, Srinagarind Hospital, Faculty of Medicine and Faculty of Dentistry, Khon Kaen University. The 123 case samples were collected during the 3 months of April-June 2012. The research instrument was a form for general data record and follow-up data record and then the data were analyzed by statistic and percentage. From the 123 cases of the 4-5 years old patients with cleft lip and cleft palate who received treatment at Tawanchai Center Srinagarind Hospital, it was found that 120 cases or 97.56 percent had an operation, 20 cases (16.26 percent) were found where patients came from Khon Kaen Province, 10 cases of each male and female. For this treatment, the majority (108 cases) used government insurance cards. The patients with cleft lip and cleft palate were most common and found to be 74 cases consisted of 44 male and 30 female. The diagnosis and follow-up of cleft lip and cleft palate patients were classified into 18 age ranges, with a total of 2,269 follow-up visits. The most common follow-up was for the 2-3 year old patients, which consisted of 410 times or 18.07 percent which consisted of 220 male and 190 female. Regarding the age range of the patients for the first diagnosis, the highest amount was 38 cases or 30.89 percent

    We evaluated the effects of presurgical nasoalveolar molding (NAM) with an orthopedic appliance and compared them with a passive orthopedic method (Hotz plate, HP), focusing on the naris morphology and width of the alveolar and palate cleft gap. The subjects were 28 unilateral complete cleft lip and palate patients treated with primary cheiloplasty at Tsukuba University Hospital from 2004 to 2011. Thirteen patients were treated preoperatively with NAM (NAM group), and 15 with HP (HP group). The surgical outcome was assessed according to left-right naris symmetry, as measured by the area ratio, perimeter ratio, aspect a/u ratio (aspect ratio of the affected side/aspect ratio of the unaffected side), and Hausdorff distance. In addition, the alveolar and palate cleft width was measured at the times of orthopedic plate setting and primary cheiloplasty. The aspect ratio was significantly smaller in the NAM group than in the HP group before the operation. In both groups, the aspect ratio, perimeter ratio, and Hausdorff distance were significantly smaller after the operation than before. The width of the alveolar and palate cleft gap was significantly narrowed in the NAM group, and the cleft gap at the initiation of NAM correlated significantly with the Hausdorff distance after cheiloplasty. We found that NAM improved the form of the naris after primary cheiloplasty and decreased the palate cleft gap more effectively than HP and that the width of the palate cleft gap was correlated with the surgical outcome of the naris.

    Non-syndromic cleft lip with or without cleft palate (nsCL/P) is a common craniofacial anomaly with a complex and heterogeneous etiology. Knowledge regarding specific genetic factors underlying this birth defect is still not well understood. Therefore, we conducted an independent replication analysis for the top-associated variants located within the DLG1 locus at chromosome 3q29, which was identified as a novel cleft-susceptibility locus in our genome-wide association study (GWAS). Mega-analysis of the pooled individual data from the GWAS and replication study confirmed that common DLG1 variants are associated with the risk of nsCL/P. Two SNPs, rs338217 and rs7649443, were statistically significant even at the genome-wide level (ptrend  = 9.70E-10 and ptrend  = 8.96E-09, respectively). Three other SNPs, rs9826379, rs6805920 and rs6583202, reached a suggestive genome-wide significance threshold (ptrend  < 1.00E-05). The location of the strongest individual SNP in the intronic sequence of the gene encoding DLG1 antisense RNA suggests that the true causal variant implicated in the risk of nsCL/P may affect the DLG1 gene expression level rather than structure of the encoded protein. In conclusion, we identified a novel cleft-susceptibility locus at chromosome 3q29 with a DLG1 as a novel candidate gene for this common craniofacial anomaly. This article is protected by copyright.

    This retrospective study was carried out on consecutively collected dental casts, x-rays, and photos of 129 Swedish children who had been born with non-syndromic unilateral (U) cleft lip (CL), cleft lip and alveolus (CLA), or cleft lip and palate (CLP). The following dental characteristics were investigated in the primary and permanent dentitions: 1. the presence, eruption, position, and shape of the lateral incisor; 2. the prevalence of rotation and enamel hypoplasia of the permanent central incisor; 3. the occurrence of hypodontia outside the cleft region; and 4. the transition from the primary to the succeeding permanent lateral incisor in the cleft region. Patients with clefts involving the palate (UCLP) exhibited a high frequency of hypodontia. In patients with clefts, which did not include the palate, malformed lateral incisors were a common finding. In the primary and permanent dentition, the lateral incisor had erupted distal to the cleft in 31.8 and 24.8 per cent of the UCLA and UCLP patients, respectively. No significant pattern was seen regarding the transition from the primary to the succeeding permanent lateral incisor (P = 0.15). The central incisor was rotated in 55 per cent of the patients and this positional deviation was particularly frequent in cases where the lateral incisor was missing in the premaxilla (P < 0.05). Hypodontia outside the cleft region was recorded in 15.5 per cent of the patients. Patients with UCLP had more often crossbite than patients with a UCL or a UCLA phenotype (P < 0.001).

    Trisomy 9 is a rare chromosomal abnormality usually associated with first-trimester miscarriage; few fetuses survive until the second trimester. We report two new cases of complete trisomy 9 that both present unusual phenotypic associations, and we analyze the genetic pathway involved in this chromosomal abnormality. The first fetus investigated showed Dandy-Walker malformation, cleft lip, and cleft palate) at the second trimester scan. Cardiovascular abnormalities were characterized by a right-sided, U-shaped aortic arch associated with a ventricular septal defect (VSD). Symmetrical intrauterine growth restriction and multicystic dysplastic kidney disease were associated findings. The second fetus showed a dysmorphic face, bilateral cleft lip, hypoplastic corpus callosum, and a Dandy-Walker malformation. Postmortem examination revealed cardiovascular abnormalities such as persistent left superior vena cava draining into the coronary sinus, membranous ventricular septal defect, overriding aorta, pulmonary valve with two cusps and three sinuses, and the origin of the left subclavian artery distal to the junction of ductus arteriosus and aortic arch. Complete trisomy 9 may result in a wide spectrum of congenital abnormalities, and the presented case series contributes further details on the phenotype of this rare aneuploidy. Copyright © 2014.

    The etiology of orofacial clefts is complex and relatively unknown. Variation in cleft lip with or without palate (CLP) and cleft palate alone (CP) was examined in Texas across urban-rural residence (1999 to 2003). Cases came from the Texas Birth Defects Registry (1,949 CLP and 1,054 CP) and denominator data came from vital records (254 counties; 1,827,317 live births). Variation in maternal residence was measured using four classification schemes: Rural Urban Continuum Codes, Urban Influence Codes, percentage of county in cropland, and Rural Urban Commuting Areas. Poisson regression was used to calculate rate ratios, adjusted for infant sex, plurality, gestational age, maternal parity, age, race/ethnicity, and education. Compared to the most urban referent category, living in more rural areas was associated with an increased adjusted risk of CLP. For example, the Rural-Urban Continuum Codes demonstrated elevated risks for CLP in "thinly populated areas" compared to "metropolitan-urban areas" (adjusted prevalence ratio = 1.9; 95% confidence intervals (CI) 1.2-2.8); CP was not similarly associated. Percentage of county cropland was not consistently associated with any outcome. The association patterns between non-urban residence and risk of CLP, except for percentage of cropland, suggests a constellation of exposures that may differ across urban-rural residence.

    Nonsyndromic cleft lip with or without cleft palate (CL(P)) involves fusion or growth failure of facial primordia during development. Complex segregation analysis of clefting populations suggest that an autosomal dominant gene may play a role in this common craniofacial disorder. We have ascertained 16 multigenerational families with CL(P) and tested linkage to 29 candidate genes and 139 mapped short tandem repeat markers. The candidate genes were selected based on their expression in craniofacial development or were identified through murine models. These include: TGF{alpha}, TGF{beta}1, TGF{beta}2, TGF{beta}3, EGF, EGFR, GRAS, cMyc, FGFR, Jun, JunB, PDFG{alpha}, PDGF{beta}, IGF2R, GCR Hox7, Hox8, Hox2B, twirler, 5 collagen and 3 extracellular matrix genes. Linkage was tested assuming an autosomal dominant model with sex-specific decreased penetrance. Linkage to all of the candidate loci was excluded in 11 families. RARA was tested and was not informative. However, haplotype analysis of markers flanking RARA on 17q allowed exclusion of this candidate locus. We have previously excluded linkage to 61 STR markers in 11 families. Seventy-eight mapped short tandem repeat markers have recently been tested in 16 families and 30 have been excluded. The remaining are being analyzed and an exclusion map is being developed based on the entire study results.

    Nonsyndromic cleft lip with or without cleft palate (NSCL/P) is a group of common human birth defects with complex etiology. Although genome-wide association studies have successfully identified a number of risk loci, these loci only account for about 20% of the heritability of orofacial clefts. The "missing" heritability may be found in rare variants, copy number variants, or interactions. In this study, we investigated the role of low-frequency variants genotyped in 1995 cases and 1626 controls on the Illumina HumanCore + Exome chip. We performed two statistical tests, Sequence Kernel Association Test (SKAT) and Combined Multivariate and Collapsing (CMC) method using two minor allele frequency cutoffs (1% and 5%). We found that a burden of low-frequency coding variants in N4BP2, CDSN, PRTG, and AHRR were associated with increased risk of NSCL/P. Low-frequency variants in other genes were associated with decreased risk of NSCL/P. These results demonstrate that low-frequency variants contribute to the genetic etiology of NSCL/P. © 2017 Wiley Periodicals, Inc.

    Nonsyndromic orofacial cleft (NSOFC) is a complex disease of still unclear genetic etiology. To investigate the contribution of rare epithelial cadherin (CDH1) gene variants to NSOFC, we target sequenced 221 probands. Candidate variants were evaluated via in vitro, in silico, or segregation analyses. Three probably pathogenic variants (c.760G>A [p.Asp254Asn], c.1023T>G [p.Tyr341*], and c.2351G>A [p.Arg784His]) segregated according to autosomal dominant inheritance in four nonsyndromic cleft lip with or without cleft palate (NSCL/P) families (Lod score: 5.8 at θ = 0; 47% penetrance). A fourth possibly pathogenic variant (c.387+5G>A) was also found, but further functional analyses are needed (overall prevalence of CDH1 candidate variants: 2%; 15.4% among familial cases). CDH1 mutational burden was higher among probands from familial cases when compared to that of controls (P = 0.002). We concluded that CDH1 contributes to NSCL/P with mainly rare, moderately penetrant variants, and CDH1 haploinsufficiency is the likely etiological mechanism. © 2015 WILEY PERIODICALS, INC.

    Introduction: Cleft lip and palate are among the most common congenital anomalies worldwide. This study was conducted in order to explore the incidence and related factors of cleft lip and/or palate (CL/P) among live births in Mashhad, North-Eastern Iran. Materials and Methods: In this cross-sectional study, records of 28,519 infants born between March 1982 and March 2011 at three major hospitals in Mashhad were screened for oral clefts. Clinical and demographic factors relating to diagnosed cases, including birth date, gender, birth weight, maternal age, number of pregnancies, type and side of cleft and presence of other congenital anomalies were recorded for analysis. Results: The overall incidence of CL/P was 1.9 per 1,000 live births. Cleft lip associated with cleft palate (CLP) was the most prevalent type of cleft (50%), followed by isolated cleft lip (35.2%) and isolated cleft palate (14.8%). A total of 92.6% of oral clefts were bilateral and 5.5% were located on the right side. In addition, clefts were found to be more common in male than female births (male/female ratio=2.3). The rate of associated congenital anomalies in CL/P newborns was 37%. No significant differences were observed in the incidence of oral clefts across three decades of study; except for CLP which was significantly more prevalent between 2002–2011 (P=0.027). There were no significant differences with regard to season of birth, associated anomalies or maternal age of affected newborns in the three time periods of the study. Furthermore, maternal age and number of pregnancies were not significantly different among the three types of cleft (P=0.43 and P=0.91, respectively). Although the mean birth weight of patients affected with isolated cleft palate was considerably lower than that of the other two types of cleft, the difference was not statistically significant (P=0.05). Conclusion: This study indicates a frequency of CL/P close to the findings in East Asian countries and higher than

    Despite the reported occurrence of dental anomalies of cleft lip and palate, little is known about their prevalence in children from Northern Finland with cleft lip and palate. The aim was to investigate the prevalence of dental anomalies among patients with different types of clefts in Northern Finland. Design and Statistics: patient records of 139 subjects aged three years and older (with clefts treated in Oulu University Hospital, Finland during the period 1996-2010 (total n. 183) were analysed for dental anomalies including the number of teeth, morphological and developmental anomalies and their association with the cleft type. The analyses were carried out using Chi-square test and Fisher's exact test. Differences between the groups were considered statistically significant at p values < 0.05. More than half of the patients had clefts of the hard palate, 18% of the lip and palate, and 13% of the lip. At least one dental anomaly was detected in 47% of the study population. Almost one in three (26.6%) subjects had at least one anomaly and 17.9% had two or three anomalies. The most common type of anomaly in permanent teeth were missing teeth followed by supernumerary teeth. Supernumerary teeth were significantly more apparent when the lip was involved in the cleft compared with palatal clefts. Missing teeth were less prevalent among those 5 years or younger. The prevalence of different anomalies was significantly associated with the cleft type in both age groups. Dental anomalies are more prevalent among cleft children than in the general population in Finland. The most prevalent anomalies associated with cleft were missing and supernumerary teeth.

    Objectives : To determine the impact of orofacial clefts on the oral health-related quality of life of affected children and whether the oral health-related quality of life of children with orofacial clefts differs among different age groups. To assess whether the responses of children with orofacial clefts differ from the caregivers' perceptions of their child's oral health-related quality of life and compare with data from a control group. Design : Cross-sectional study. Patients/Setting : A total of 75 subjects with cleft lip and/or cleft palate (mean age, 13.0 years) from the Nationwide Children's Hospital Craniofacial Anomalies Clinic, as well as their caregivers, and 75 control subjects (mean age, 13.9 years). Main Outcome Measure : Self-reported oral health-related quality of life measured with the Child Oral Health Impact Profile, a reliable and valid questionnaire designed for use with children and teenagers. Results : Children with orofacial clefts had statistically significant lower quality of life scores than control subjects had for overall oral health-related quality of life, Functional Well-being, and Social Emotional Well-being. There was a statistically significant difference in the interaction of age group and Social-Emotional Well-being between children with orofacial clefts and control children. No statistically significant differences were found between the responses of children with orofacial clefts and their caregivers' reports. Conclusions : Presence of an orofacial cleft significantly decreases overall oral health-related quality of life, Functional Well-being, and Social-Emotional Well-being in children and adolescents. The negative impact of orofacial clefts on Social-Emotional Well-being is greater in 15- to 18-year-olds than in younger age groups. Children with orofacial clefts and their caregivers had very similar evaluations of the child's oral health-related quality of life.

    Studies about maxillary sinuses of cleft lip-palate patients have increased since sinusitis is commonly observed in these patients. It is evident that maxillary sinus will be morphologically affected in these patients. And anatomic differences may be a cause or at least a contributor of sinusitis. The aim of this study was to compare maxillary sinus volumes of the non-syndromic patients with unilateral cleft lip-palate and control group by using Cone-Beam computed tomography. Tomography scans of 44 unilateral cleft lip-palate patients (18 right and 26 left) with age and gender matched 45 control patients were evaluated for the study. The images used in the study were part of the diagnostic records collected due to dental treatment needs. All tomographs were obtained in supine position by using Cone-Beam computed tomography (NewTom 5G, QR, Verona, Italy). The patient-specific Hounsfield values were set to include the largest amount of voxels in the sinuses volume calculation individually. All data were measured in mm(3). There was no statistically difference between the gender and age distributions of the groups. No statistically significant difference was found on the cleft and non-cleft side, the right and left side of the unilateral cleft lip-palate patients and the control group (P>0.05). For the inter group comparison, mean maxillary sinus volumes volume of unilateral cleft lip-palate patients (9894.55±4171.44mm(3)) was statistically smaller than the control group (11,977.90±4484.93mm(3)) (P<0.05). Maxillary sinus volumes were effected negatively in unilateral cleft lip-palate patients when compared with the healthy control group. No difference was found on the cleft, non-cleft side and the right-left side of the unilateral cleft lip-palate patients. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    Objective : The purpose of this cross-sectional study was to assess the prevalence of dental caries in children with cleft lip, alveolus, and/or cleft palate living in central Germany between 1996 and 2010. Participants : A total of 295 children 1 to 6 years of age from three birth cohorts (BC) with clefts from central Germany were included in the study. They were compared with 548 1- to 6-year-old cleft-free children from the same region. Setting : Children with clefts underwent a dental examination in an outpatient dental clinic at the University of Leipzig. The first BC was examined between 1996 and 1998, the second between 2002 and 2004, and the third between 2008 and 2010. Controls were examined at day-care centers in Leipzig during the same periods. Main Outcome Measure : The standard dental caries index for the primary dentition (dmf/t3-4) was used for clinical assessment. Results : Over the entire study period, the mean prevalence of dental caries in deciduous teeth was significantly higher (1.32 dmf/t3-4) in children with clefts compared with cleft-free children. However, a decline in caries (approximately 1 dmf/t3-4) and an increase in the proportion of children with healthy primary dentition were observed in both groups. These results represent a caries decline of 61% in children with clefts. Conclusions : Caries rates for children 1 to 6 years of age with clefts from central Germany showed a considerable decline over the last years. The caries rates for clefts patients in the third BC (2008 to 2010) was similar to that of cleft-free children in the first BC (1996 to 1998).

The lateral cephalograms of 66 patients with complete cleft lip and palate were measured and compared retrospectively to the cephalograms of 123 healthy probands. Measurements were derived from a standardized analysis of 56 landmarks. Results. We observed significant differences between cleft and control group: the cleft patients showed amaxillary retroposition and a reduced maxillary length; the inclination of the maxilla was significantly more posterior and cranial; the anterior nasopharyngeal height was reduced; the nasopharyngeal growth followed a vertical tendency with reduced sagittal dimensions concerning hard and soft tissue. The velum length was reduced. In the cleft group, an accumulation of mandibular retrognathia and an anterior position of the hyoid were observed. Skeletal configuration and type of growth were predominantly vertical. Conclusions. Our data provides a fundamental radiological analysis of the nasopharyngeal development in cleft patients. It confirms the lateral cephalogram as a basic diagnostic device in the analysis of nasopharyngeal and skeletal growth in cleft patients. PMID:22523495

    The aim of this study was to analyze the association of potential risk factors such as positive family cleft history, smoking, use of drugs during pregnancy, and parental age with oral clefts in offspring within the Kosovo population. We conducted a population-based case-control study of live births in Kosovo from 1996 to 2005. Using a logistic regression model, 244 oral cleft cases were compared with 488 controls. We have excluded all syndromic clefts. Heredity increases the risk of clefts in newborns [odds ratio (OR) = 8.25, 95% confidence interval (CI) 3.12-23.52]. Clefts were also associated with smoking (OR = 1.87, 95% CI 0.75-4.08), use of drugs during pregnancy (OR = 2.25, 95% CI 0.82-5.12), increasing maternal age (OR = 1.83, 95% CI 1.42-2.49), and increasing paternal age (OR = 1.3, 95% CI 1.2- 1.4). We found heredity to be the most important factor for cleft occurrence in Kosovar newborns. Another significant potential risk factor for occurrence of clefts is the parental age. We found the use of drugs and smoking during pregnancy to be less significant.

    To assess dental age in children with a complete unilateral cleft lip and palate and to compare this with a noncleft control group. Two-group, mixed-longitudinal cohort study. Cleft group from an academic center for cleft lip and palate treatment. Noncleft control group from the same population. Participants included 70 Caucasian children with a full complement of teeth and a complete unilateral cleft lip and palate (45 boys and 25 girls) from the Cleft Palate Craniofacial Center at the Radboud University Nijmegen Medical Center, Nijmegen, the Netherlands. The control group (90 boys and 91 girls) was taken from the Nijmegen Growth Study. Dental age was assessed on orthopantomograms. In the unilateral cleft lip and palate group, linear interpolation in individual age curves was applied to obtain the dental age at 5, 9.5, and 14 years of age. For these ages, a comparison was made with the noncleft control group. Boys and girls with a unilateral cleft lip and palate showed a significant delay in dental age, as compared with their noncleft peers at all three ages. This delay was more pronounced in boys than in girls. The gender effect was significant at chronological ages 5 and 14 years. Children with a complete unilateral cleft lip and palate have a delay in dental age, compared with noncleft children.

    We report a small cohort of patients with severe osteoporotic fractures treated with vertebroplasty. We note a high prevalence of small, central, intraosseous clefts in these severe fractures. Rather than filling the small amount of residual bone marrow around the periphery of these severe fractures, as suggested by previous authors, we suggest central needle placement to fill these central clefts.

    Adult patients who did not receive proper treatment for cleft palate are challenging for clinicians in terms of prosthetic rehabilitation. Moreover, during the late stages of adulthood when patients become edentulous, prosthetic reconstruction becomes even more challenging. This clinical report describes the prosthetic rehabilitation of 2 edentulous geriatric patients with unrepaired cleft palate by placement of dental implants after closure of the oronasal communications.

    Alveolar bone grafting is an integral part of the treatment concept in cleft palate patients. As an alternative to autogenous bone, tissue-engineered grafts have found some clinical application. The aim of the present study has been to compare ossification in the cleft area using tissue-engineered grafts in a case series of patients with ossification after transplantation of autogenous spongious bone as the gold standard in alveoloplasty. Eight children with complete cleft lips and cleft palates were included in the study. In four children (group A), the cleft defect was filled with tissue-engineered bone (autogenous osteoblasts cultured on demineralized bone matrix Osteovit(®)); as control in another 4 children (group B), the alveoloplasty was performed using spongious iliac bone. Preoperative and 6 months postoperative cone-beam computed tomography was performed, and volumes of the remaining cleft defects were calculated using 3D navigation software. Wound healing was uneventful in both groups. Six months postoperatively the mean volume of the cleft was 0.55±0.24cm(3) after grafting of tissue-engineered bone (group A) and 0.59±0.23cm(3) after transplantation of autogenous spongiosa. In group A, 40.9% of the cleft defect was ossified; in the control group (group B), 36.6%. Tissue-engineered bone is a promising alternative in alveolar bone grafting and no disadvantages were observed in comparison to the gold standard. Copyright © 2012 Elsevier GmbH.

      The purpose of the present study was to compare mandibular vertical asymmetry in patients with unilateral and bilateral cleft lip and palate and subjects with normal occlusion.   Cone beam computed tomography scans of three groups consisting of 20 patients with unilateral cleft lip and palate, 20 patients affected by bilateral cleft lip and palate, and a control group of 20 subjects with normal occlusion were analyzed for this study. Condylar, ramal, and condylar plus ramal asymmetry indices were measured for all subjects using the method of Habets et al. Kruskal-Wallis and Mann-Whitney tests were used to determine any significant differences between the groups for all indices at the 95% level of confidence.   There were no significant differences regarding sex for all mandibular asymmetry indices in all three groups. All Asymmetry indices (condylar, ramal, and condylar plus ramal asymmetry) were significantly higher in the unilateral cleft group compared with the other two groups.   Cone beam computed tomography images showed that patients with cleft lip and palate suffered from mandibular asymmetry. Subjects with unilateral cleft lip and palate had a more asymmetric mandible compared with the bilateral cleft lip and palate and control groups. Therefore, the mandible appears to be the leading factor in facial asymmetry in subjects with unilateral cleft lip and palate.

    During the first counselling after the birth of a child with cleft lip and palate (CLP) information about the malformation should be delivered and a long-standing relationship between the cleft team and the affected family must be established. The present study was conducted to evaluate the parents' experiences, needs and expectations with this first consultation. A questionnaire was sent to 105 parents at the cleft clinic, which could be answered anonymously. It collected demographic data, data on the parents' pre-existing level of information and the parents' assessment of the counselling at the cleft centre. Seventy percent of the questionnaires were returned. In 16% the clefts were diagnosed prenatally, in 32% there were relatives with clefts. Seventy-one percent of the parents received detailed counselling, 89% of which occurred in the first week. The parents requested that information about surgery (80%), feeding the child (63%) and the aetiology of clefts (44%) should be given. The quality of the consultation was rated very good or good by 87% of families. This study confirms the importance of initial counselling for CLP. The exceptional psychological situation of the family has to be considered and a close collaboration between cleft centre and maternity hospitals is mandatory.

    Previous genomewide association studies (GWAS) identified a region near MAFB at chr20q12 associated with non-syndromic orofacial clefts (NSOC) susceptibility. However, whether other SNPs in this area could independently contribute to non-syndromic orofacial clefts in Chinese populations remained obscure. We selected 24 SNPs based on a haplotype-tagging SNP strategy and evaluated their associations with risk of non-syndromic orofacial clefts in a large-scale two-stage case-control study with 1278 cases and 1295 controls. Genotyping was performed with Sequenom and TaqMan assay. Associations between the SNPs and risk of non-syndromic orofacial clefts were estimated from unconditional logistic regression analyses. Overall, six SNPs were found to be the susceptible factors of non-syndromic orofacial clefts. The most significant and independent SNP was rs6129653 (additive model of P value = 1.4E-06). In subgroup analysis, its significant associations with cleft lip only (CLO) and cleft lip and palate (CLP) were observed. Furthermore, in silico bioinformatics analysis indicated that rs6129653 was located in the transcriptionally active region and associated with MAFB expression in human brain tissues. Rs6129653 was an independent locus of non-syndromic orofacial clefts among Chinese populations possibly due to its potential of distal transcriptional regulation of MAFB expression. © 2016 John Wiley & Sons A/S.

    Background: Cleft lip (CL) and palate (CLP) management is multidisciplinary. A cleft team was formed in a Nigerian Tertiary Hospital to address the health needs of cleft patients in the centre. Aim: This paper aims at documenting the Aminu Kano Teaching Hospital (AKTH) management protocol for orofacial clefts and also to review our experience with CLP surgeries performed at AKTH since our partnering with Smile Train. Materials and Methods: A retrospective review of all the cleft patients surgically treated from January 2006 to December 2014 under Smile Train sponsorship was undertaken. A descriptive narrative of the cleft team protocol was also given. Results: One hundred and fifty-five patients (80 males, 75 females) had surgical repairs of either the lip or palate. CL patients were 83 (53.55%), while CLP patients were 45 (29.03%) and isolated cleft palate patients were 27 (17.42%). Conclusion: The inclusion of various specialities in the cleft team is highly desirable. Poverty level amongst our patients frequently limits our management to surgical treatment sponsored by the Smile Train, despite the presence of other residual problems. PMID:26712291

    Background: Restoration of proper anatomy and physiology is an integral part of cleft palate repair. The senior author has devised a new technique of radical release of greater palatine vessels, which helps in achieving tension-free closure of palatal cleft. In addition, release and transposition of palatal muscles is performed without the use of operative microscope, resulting in improved palatal function. This technique is applicable to all types of clefts of the palate and can be performed on adult patients as well. Materials and Methods: This is a retrospective case series of cleft palate repairs performed over a period of 3 years. Single-stage repair with modified Bardach’s technique for complete cleft palate and von Langenbeck’s technique for incomplete cleft palate with radical release of greater palatine vessels and levator complex retropositioning was performed. The outcome measures were closure of palatal defect and speech production. A follow-up of at least 6 months was completed in each patient. Results: A total of 1568 patients were included in the study. Their age ranged from 9 months to 54 years. The overall fistula rate was 6.1%. Improvement of speech was observed even in adult patients. Conclusions: Radical release of greater palatine artery and levator complex transposition can dramatically improve results of cleft palate repair. This technique helps in dynamic reconstruction of cleft palate and can be effectively applied in all age groups. PMID:28280675

  20. Effect of ion concentration changes in the limited extracellular spaces on sarcolemmal ion transport and Ca2+ turnover in a model of human ventricular cardiomyocyte.

    We have developed a computer model of human cardiac ventricular myocyte (CVM), including t-tubular and cleft spaces with the aim of evaluating the impact of accumulation-depletion of ions in restricted extracellular spaces on transmembrane ion transport and ionic homeostasis in human CVM. The model was based on available data from human CVMs. Under steady state, the effect of ion concentration changes in extracellular spaces on [Ca2+]i-transient was explored as a function of critical fractions of ion transporters in t-tubular membrane (not documented for human CVM). Depletion of Ca2+ and accumulation of K+ occurring in extracellular spaces slightly affected the transmembrane Ca2+ flux, but not the action potential duration (APD90). The [Ca2+]i-transient was reduced (by 2%-9%), depending on the stimulation frequency, the rate of ion exchange between t-tubules and clefts and fractions of ion-transfer proteins in the t-tubular membrane. Under non-steady state, the responses of the model to changes of stimulation frequency were analyzed. A sudden increase of frequency (1-2.5 Hz) caused a temporal decrease of [Ca2+] in both extracellular spaces, a reduction of [Ca2+]i-transient (by 15%) and APD90 (by 13 ms). The results reveal different effects of activity-related ion concentration changes in human cardiac t-tubules (steady-state effects) and intercellular clefts (transient effects) in the modulation of membrane ion transport and Ca2+ turnover.
