Abstract:
To elucidate the contribution of the extracellular microfibril–elastic fiber network to vertebrate organogenesis, we generated fibrillin 2 (Fbn2)–null mice by gene targeting and identified a limb-patterning defect in the form of bilateral syndactyly. Digit fusion involves both soft and hard tissues, and is associated with reduced apoptosis at affected sites. Two lines of evidence suggest that syndactily is primarily due to defective mesenchyme differentiation, rather than reduced apoptosis of interdigital tissue. First, fusion occurs before appearance of interdigital cell death; second, interdigital tissues having incomplete separation fail to respond to apoptotic clues from implanted BMP-4 beads. Syndactyly is associated with a disorganized matrix, but with normal BMP gene expression. On the other hand, mice double heterozygous for null Fbn2 and Bmp7 alleles display the combined digit phenotype of both nullizygotes. Together, these results imply functional interaction between Fbn2-rich microfibrils and BMP-7 signaling. As such, they uncover an unexpected relationship between the insoluble matrix and soluble factors during limb patterning. We also demonstrate that the Fbn2- null mutation is allelic to the recessive shaker-with-syndactyly (sy) locus on chromosome 18.

Abstract:
Purpose: Being one of the most common congenital hand malformations, syndactyly is repaired by orthopedic, plastic, and fellowship-trained general surgeons. Limited multi-institutional outcomes analyses regarding incidence, timing, and type of repair exist. Methods: All syndactyly cases performed over a 5-year period from 2012-2016 were isolated from the National Surgical Quality Improvement Program Pediatric database. Patient demographics, surgical factors, perioperative outcomes, and risk factors were analyzed using χ2, Fisher exact, and t-test analysis. Results: A total of 956 patients who underwent syndactyly repair were identified. Most cases were simple syndactyly with nearly even case distribution among plastic and orthopedic surgeons. Most patients were men and Caucasian. Mean age at the time of surgery was 2.6 years. Most cases were performed as outpatient surgery. Patients of plastic surgeons had significantly more airway abnormalities and shorter operative times. Patients with complex syndactyly had significantly more ventilator dependence, tracheostomy, and comorbidities when compared with those with simple syndactyly. Cases with complex syndactyly also had longer operative times and a higher rate of superficial surgical site infections. Conclusions: Syndactyly repair is a safe procedure with few major or minor reconstructive complications regardless of the surgical specialty or syndactyly type. Patients with complex syndactyly have significantly more preoperative comorbidities with comparable outcomes. orthopedic surgeons have significantly longer operative times than plastic surgeons, likely due to caring for increased number of patients with complex syndactyly.

Abstract:
Background: As the most prevalent form of congenital hand malformation, syndactyly carries significant aesthetic and practical implications. For the vast majority of situations, surgery is the best option. Congenital syndactyly can be repaired with skin grafts and local flaps, however the results are often less functional and cosmetic than anticipated and often leave scars and residual syndactyly. So we set out to find out how children's syndactyly healing went in this study.1 Objective: To analyze the functional outcome of syndactyly repair in children presenting in a tertiary care hospital. Methodology: This Descriptive case series was conducted at Department of Plastic and Reconstructive Surgery, LUMHS Jamshoro / Hyderabad for 6 months. Sample size of 180 cases was recruited through Non-probability consecutive sampling. Then all patients underwent surgery under general anesthesia. In all cases, procedure was performed depends upon the type / extent of syndactyly. Then patients were discharged after recovery and were followed up on 1st, 2nd and 3rd months post operatively for assessment of functional outcome of syndactyly repair i.e. no supination and no pronation was noted. All this information was noted on proforma. Data was entered and analyzed using SPSS 22.0. Results: The mean age of children was 6.30+3.55. There were 66 (37%) females and 114 (63%) male in the sample. There were 128 (71%) cases of simple syndactyly and 52 (29%) cases of complex syndactyly. There were 127 (71%) cases who had no-supination, 162 (90%) cases who had no-pronation. There was significant difference observed between both type of syndactyly (P<0.05) for supination while insignificant for pronation. Conclusion: Thus we have found that syndactyly repair is effective technique through which we can attain success in maximum number of patients which can help in achieving normal angulation of fingers after surgery. Key words: Syndactyly, Pronation, Supination, Angulation, Children

O objetivo do presente estudo foi caracterizar, por exames de imagem, uma população de porcos naturalmente portadores de sindactilia, bem como avaliar-lhes os parâmetros cinéticos e têmporo-espaciais. Foram utilizados 10 miniporcos brasileiros (Sus domesticus), não castrados, com idade entre 6 e 8 meses, dos quais se constituíram dois grupos experimentais. O Grupo 1 foi composto de cinco animais clinicamente saudáveis, com massa corpórea entre 10,5 e 18,5 kg, enquanto o Grupo 2, por animais portadores de sindactilia, com massa corpórea entre 7,5 e 18,0 kg. Em ambos os grupos, efetuaram-se exames radiográficos e tomográficos dos membros torácicos e pélvicos, além da análise da locomoção com o emprego de plataforma de pressão. Pelos exames de imagem, os animais do grupo 2 apresentaram os quatro membros comprometidos. Nos membros torácicos, detectaram-se dois animais de membros com sindactilia complexa 1 e oito com sindactilia complexa 2. Nos membros pélvicos, observaram-se quatro indivíduos com sindactilia simples, um com sindactilia complexa 1 e cinco com sindactilia complexa 2. Entre os grupos, não se constatou diferença estatística nos valores cinéticos e têmporo-espaciais, bem como nos índices de simetria. A superfície plantar e a superfície palmar dos porcos clinicamente normais tinham dois picos de pressão, ao passo que os com sindactilia tinham apenas um pico de pressão. Foi possível concluir que, na população avaliada, o tipo de sindactilia mais comum foi a complexa 2 e, a despeito das alterações, a maioria dos dados obtidos com o uso da plataforma de pressão foi similar à dos animais normais
Ten Brazilian mini pigs (Sus domesticus), from 6 to 8 months old, were divided into two groups: Group 1 - five healthy animals weighing from 10.5 to 18.5 kg and Group 2 - five animals with syndactyly weighing from 7.5 to 18.0 kg. In both groups radiographic and computed tomography studies were performed in the fore and hind limbs. Moreover, gait analysis was performed by using pressure sensing walkway. Imaging studies showed that the animals had involvement of all limbs. In particular, one limb with complex-1syndactyly and eight limbs with complex-2 syndactyly were detected in the forelimbs. In the hind limbs, four limbs with simple syndactyly, one limb with complex-1 syndactyly and five limbs with complex-2 syndactyly were observed. There were no significant differences of the kinetic and temporospatial values between groups as well as in the symmetry indices. The plantar surface of the feet and palmar surface of the hands of the clinically healthy pigs had two peak pressure plots whereas only one peak pressure plot was observed in pigs with syndactyly. In conclusion, in the evaluated population the most common type of syndactyly was complex-2 and despite of the lesions, most of data obtained using pressure sensing walkway was similar to those of normal pigs

Abstract:
Communication is a behavioral strategy used by species in the competition for survival and reproduction. Animals produce signals that are sent to receivers and occasionally transmit information that can be beneficial in a variety of contexts including avoiding predators, locating food resources, and maintaining the pair bond between partners. Researchers are interested in if auditory signals are variable and if the variability is biologically meaningful to receivers. Some species, such as siamang, sing duets as their form of acoustic communication and these duets have been studied for a variety of purposes such as investigating their structure, variability, and functionality. Siamang are a species of gibbon that combine a finite number of call units into structurally complex sequences in rule-governed ways, hereby conveying different contextual situations. Some wild gibbon species have demonstrated variation in the temporal structure of their duets and the distinctiveness in acoustic timing is unique enough for researchers to distinguish among individuals and groups based on their duet contributions. The process of coordinating and producing a uniquely timed duet could function in relation to the formation and maintenance of the pair bond. This dissertation analyzed the temporal variation and call order of wild siamang (Symphalangus syndactylus) duets that are comprised of four distinct sequences comprised of several note types. Previous research has provided detailed descriptions of captive siamang duets that include category descriptions of four call types: grunting, introduction, interlude, and great call. While these descriptions provide a general understanding of the structure of siamang duets, they can be confusing and difficult to study empirically due to their arbitrary nature. For instance, the siamang great call has been described as occurring in over 30 variants and in stable, or typical, and unstable, or atypical forms. The stable or typical form of the great call has been described to occur only after the male’s first bitonal scream. This previous research did not measure the timing of sequences through entire duets or conduct individual note analyses. Also, the most detailed investigations of siamang duets were conducted with captive animals and therefore wild siamang duets have not been quantitatively analyzed. This dissertation research measures the temporal variation of wild siamang duet call types, and the call order of individual notes in the US-II phrase. The findings will provide a more objective description of the siamang duet as well as determine if it has a more stereotyped or flexible nature. Also, in the wake of globalization, duets and other behaviors (such as travel) could be sensitive to anthropogenic disturbances. So, I am interested in how wild siamang might be impacted by human presence. The three main objectives of this dissertation are: 1) document the temporal variation in the call types of wild siamang; 2) document variation in the call order of wild siamang US-II phrases; and 3) document how wild siamang travel is impacted by anthropogenic noise. The study was conducted at 4 remote field sites in northern Sumatra, Indonesia from August 2017 through May 2018. With the assistance of a research team, I recorded acoustic and behavioral data from 10 siamang groups and two individual females. I collected acoustic data using a combination of autonomous recording units and handheld recording devices while following the study subjects on foot. I marked GPS points during behavioral scans and conducted experimentally induced noise playback experiments. I analyzed the audio data with the software program Raven Pro 1.6 and spectrograms were produced with a 512-point (11.6 ms) Hann window (3 dB bandwidth = 135 Hz), with 50% overlap and a 512-point DFT, yielding time and frequency measurement precision of 2.9 ms and 43.1 Hz. I conducted statistical testing in R Studio Version 1.3.959 in conjunction with the statistics lab at Southern Illinois University. In Chapter 3, I performed multilevel regression analysis in the form of a Generalized Linear Mixed Model (GLMM) in order to investigate temporal variation the time spent singing call types (grunting, introduction, interlude, and great call) accounting for differences between songs, groups, and field sites. I used a Bayesian hierarchical model to avoid calculating estimates using data with repeated and imbalanced sampling, and explicitly model variation within individuals, between songs, between groups, and field sites. In Chapter 4, I used the Levenshtein Distance (LD) method for investigating structural variation in the call order of US-II phrases in the siamang duet. The LD method is a quantitative technique for measuring the similarity of sequences and to quantify the differences between strings of data. In Chapter 5, I used the Friedman test to compare the means of distances traveled in 5-minute intervals in the following conditions: pre-playback, cicada (control), traffic, jackhammer, and music. I used post hoc tests with Bonferroni correction to analyze the pairwise comparisons of the five experimental conditions. Overall, the results suggest support of previous studies on the variability of the gibbon duet and animal travel in response to noise. In Chapter 3, I found some temporal variation in call types to exist at all levels of the modeling but only statistically significant when comparing the field sites of Ketambe and Kutapanjang. Relating to the functionality of total call duration, I did not find significant differences in the behavioral categories before or after any of the calls regardless of their total duration. In Chapter 4, I found US-II phrases are not as stereotyped as previous descriptions have suggested. The mean LD distances were higher than those compared by other duetting primates. Also, the results from one-way ANOVA and Games-Howell Post Hoc Testing showed significant mean differences between groups. In Chapter 5, I found siamang are impacted by noise as they traveled further after the anthropogenic noise playback experiments compared to pre-playback travel. However, the pairwise comparisons were not statistically significant and therefore I could not determine which noise condition caused the change in travel distance. Collectively, the results of this dissertation suggest that there is considerable variability in both wild siamang call types and call order in a previously described stereotyped phrase, and that wild siamang travel away is impacted by introduced anthropogenic noise. What this contributes to the field of vocalization studies is further support that precise measurement of song parameters gives a better understanding of song structure than somewhat arbitrary written descriptions. It is important to have descriptions of notes produced in songs, but to understand how those notes relate to each other, an individual note analysis and rigorous statistical methodology is necessary. The variation found in this dissertation could be due to the unique siamang response to their partner’s timing in the process of forming the pair bond. But as the siamang duet is thought to have multiple functions, the temporal variation could also be transmitting other information such as individual and group identity while functioning in territorial defense. In addition, anthropogenic noise caused the animals to change their travel behavior and this suggests it could be harmful if faced on a regular basis. Anthropogenic noise can be detrimental if it occurs in home ranges of species that are territorial and facing shrinking habitats due to continued human encroachment. In order to understand if these findings are biologically meaningful and to have firmer conclusions, future long-term studies will need a larger data set over longer periods of time. It is also important to have a larger data set and compare more siamang groups that live in various noise levels and measure variables such as caloric intake, daily travel, copulations, and number of offspring.

Abstract:
The current study deals with four different approaches to analyse a hereditary disease affecting bovine breeds: 1. Comparative pathology combined with comparative mapping is used when pedigrees are not sufficiently informative, 2. The production of a genome scan with genetic markers in informative pedigrees, which permits to define a reliable localization interval,3. Fine mapping to investigate candidate genes,functional genomics to obtain the expression profile of a given genomic region. These methods were used for four bovine hereditary diseases: progressive ataxia and arthrogryposis-palatoschisis for Charolais cattle, generalized caprine-like hypoplasia syndrome (SHGC) in the Montbeliarde breed, and syndactyly for Holstein cattle. They offer new perspectives for breeders (with the design of genetic tests), and raise new questions concerning the limb development in mammals. Finally, our work will renew approaches for the study of genetic traits in domestic species, especially in cattle
La présente étude traite de quatre approches moléculaires pour l'étude des anomalies génétiques présentes en race bovine: la pathologie comparée combinée à la cartographie comparée, lorsque les pedigrees à disposition ne sont pas assez informatifs, le balayage du génome à l'aide de marqueurs génétiques afin d'obtenir une primolocalisation de l'anomalie, la cartographie fine d'un intervalle déjà identifié, 4. La génomique fonctionnelle, afin de réaliser le profil d'expression d'une région génomique donnée. L'utilisation de ces méthodes sur quatre anomalies génétiques bovines (l'ataxie progressive et le Syndrome Arthrogrypose-Palais fendu en race Charolaise, le Syndrome d'Hypoplasie Généralisée Capréoliforme en race Montbéliarde et la syndactylie en race Holstein) ouvre de nouvelles perspectives, tant pour la filière bovine, avec la mise au point de tests de dépistage que pour l'étude du développement des membres des mammifères. Enfin, les nouvelles approches de génomique fonctionnelle permettent d'envisager à "avenir un renouveau dans l'étude des caractères génétiques des animaux domestiques, et en particulier des bovins

Abstract:
Smith-Lemli-Opitz syndrome (OMIM 270400) (SLOS) is a multiple congenital anomaly disorder caused by an inborn error of cholesterol synthesis. Studies demonstrated that mutations in the gene for 3b-hydroxysterol-D7 reductase (DHCR7) result in low plasma cholesterol and corresponding increases in 7DHC. Distinctive facial features of include ptosis, small nose with anteverted nares, and micrognathia. Acral dysgenesis is common, foremost of which involve syndactyly and polydactyly. Children with SLOS often have a behavioral phenotype within the autism spectrum.

Abstract:
In 1980, Hall et all described a syndrome characterized by “hamartoblastoma”, hypopituitarism, unperfurated anus, polydactyly postaxial and numerous visceral anomalies, today known as Pallister-Hall Syndrome. On the study, Hall et all reported six cases of children with that malformation syndrome - lethal on neonatal period. None of the newborns had anterior hypophysis and the hypothalamic tumor was apparent in the inferior part of the brain, going from the optic chiasm to the interpeduncular fossa. Besides, other anomalies were found, such as: laryngeal split, abnormal pulmonary lobation, renal agenesis or dysplasia, shorts fourth metacarpals, nail dysplasia, multiple mouth frenulum, hypoadrenalism, congenital cardiomyopathy and intrauterine growth retardation. Every case was sporadic, the chromosome were apparently normal, without consaguinity relations. Several similar, milder and even asymptomatic cases were described later on. Kletter and Biesecker (1992), Topf et all (1993) and Penman Splitt et all (1994), define the disease as dominant autosomal inheritance. Kettler and Biesecker (1992) stated that most cases as sporadic as a result of a gene mutation with variable expressiveness. According to Biesecker et al (1996), an international workshop determined diagnostic criteria to the Syndrome: Hypothalamic Hamartroma and Central Polydactyly; First degree relative with hypothalamic hamartroma and polydactyly; Dominant autosomal parrent inheritance or in a consistent form with germaine mosaicism. The radiological changes are important for differential diagnosis between Pallister-Hall Syndrome and other hamartroma-present diseases. The hypothalamic hamartroma isolated has phenotypical features and causes hormonal disorders such as early puberty. On the MRI (Magnetic resonance imaging) it shows hyperintese sign on attenuated fluid. On the other hand, the Pallister-Hall Syndrome the hamartroma shows itself as a isointense signs along with other deformities as polydactyly, for example. According to Kuo et al (1999), on MRI, the classic hypothalamic hamartroma isn’t calcified, is homogenous and isointense to the grey matter on weight images in T1, and isointense and often hyperintense on weight images in T2. Those findings are pretty distinctive and help distinguish the hypothalamic hamartroma from ordinary lesions, as craniopharyngioma and hypothalamic/opticalchiasmic glioma, observed in children. Case report: The patient ALDV, male, born in 30/12/1995, was referred to evaluation on the Medical Genetic Service from HCPA. At the time, aged one year and 8 months, he was the only son of a young, healthy couple with no consanguinity. The family history of similar cases or other genetic pathologies are unknown. The prenatal happened with no intercurrences, unless the smoking mother. It was a natural birth; Birth Weight: 2kg; High: 42cm; PC: 32cm. APGAR 9. At 8 months, starts an investigation for precocious puberty, and a karyotype was performed in her hometown: 46, XY (normal). He presents convulsive crises since one year old. DNPM: cephalic support when he had 8 months, sat without support at the age of one. Physical examination: Head circumference in the 97th percentile, length above the 97th percentile. Good general condition, dysmorphic, facies with fusion of eyebrows (sinofre), epicanthus, small nose, dysplastic ears with a broad shield, three café-au-lait spots on the body. Presence of pubic hair. Increase in length and diameter of the penis, as well as of the testicles, in relation to chronological age. In the hands, significant brachydactyly with bitateral hexadactyly. In the feet, bilateral hexadactyly. Proximal cutaneous syndactyly between the 2nd and 3rd bilateral arthroids, mainly on the right. Additional exams: Rx of hands and wrists for bone age: 7 years; Chronological Age: 1 year and 10 months. Normal abdominal ultrasound; Computed Tomography of Skull/Magnetic Resonance of Skull: hypothalamic expansive lesion (3 cm), compatible with hamartoma; triventricular hydrocephalus; Cavum septum pellucidum. Endocrinological Evaluation: compatible with precocious puberty of central cause. High resolution karyotype: 46, XY (normal). Computed tomography of the brain: Examination for neurological control, performed on 10/12/2014, 18-year-old patient. It was observed solid nodular formation in the hypothalamic region, hypodense, with well-defined limits, in close contact with the mesencephalon, without impregnation by contrast medium administered intravenously, measuring about 2.9 X 2.4 X 3.0 cm, in the respective laterolateral, anteroposterior and craniocaudal planes, which in correlation with the patient’s clinical history may be related to hypothalamic Hamartoma.
