As a preparatory step towards the development of a complete habilitation program for children with congenital limb anomalies associated with maternal ingestion of thalidomide, the medical records of all patients with congenital limb anomalies referred to the Rehabilitation Institute of Montreal in the past decade were studied, and an examination and a thorough reassessment were made of 41 patients (21 males and 20 females). The medical and prosthetic aspects were dealt with in Part I of this paper. Part II describes, in a joint report, the results of psychiatric, psychological and educational assessments.There was no evidence of major emotional disorder in any of the patients, although conflicts were intensified by the presence of the physical anomaly. No relation was found between intelligence, emotional adjustment and disability. The patient''s attitude towards his disability and prosthesis is definitely influenced by the degree of parental acceptance of the handicap and by the character of the emotional undertones in the total environment. In order to favour the occurrence of the healthiest modes of development in these children, the authors believe that the medical profession should be made fully aware of the physical and emotional problems which may arise after the birth of a deformed child. It is considered very important that the mother should receive psychotherapeutic support as soon as possible after the child is born. 相似文献

Since November 1961 it became apparent that the administration of thalidomide to pregnant women was associated with the occurrence of severe congenital anomalies. These deformities are frequently symmetrical, involving the limbs, particularly the proximal part, and associated with an absent external ear, mid-line facial hemangioma with saddle nose, atresia of the bowel and other congenital anomalies. Care of these children is a complicated problem requiring a team of specialists of many disciplines, particularly a pediatrician, an orthopedic surgeon, a prosthetic specialist and a social worker. Treatment by such a team ideally would commence immediately after delivery of the infant and continue until the child has been totally habilitated. Such care ideally should be provided within existing services in the country for the habilitation and rehabilitation of handicapped children. 相似文献

Congenital malformations and genetic diseases in Iranian infants 总被引:1,自引:0,他引:1
Summary Data of 13,037 live-born infants from a hospital in Tehran, Iran were analysed for congenital malformations and genetic diseases. The results showed that the rates of joint dislocation, eleft lip, cleft palate and finger anomalies are similar to those of the other populations. The rates of chromosomal, thorax and abdominal, external genital anomalies and other syndromes were higher compared with other populations, whereas the rates of multiple births and limb anomalies were lower. 相似文献

We report on a girl with congenital scalp and acral reduction limb defects, consistent with the diagnosis of Adams-Oliver syndrome. The presence of constriction rings makes the limb anomalies in this case similar to those seen in the amniotic band disruption sequence. Vascular disruption--with or without secondary amniotic rupture--may be responsible for the observed anomalies. Therefore we believe that the present observation adds further evidence for the hypothesis that the Adams-Oliver syndrome is a vascular disruption sequence. 相似文献

The power of zebrafish models for understanding the co‐occurrence of craniofacial and limb disorders
Craniofacial and limb defects are two of the most common congenital anomalies in the general population. Interestingly, these defects are not mutually exclusive. Many patients with craniofacial phenotypes, such as orofacial clefting and craniosynostosis, also present with limb defects, including polydactyly, syndactyly, brachydactyly, or ectrodactyly. The gene regulatory networks governing craniofacial and limb development initially seem distinct from one another, and yet these birth defects frequently occur together. Both developmental processes are highly conserved among vertebrates, and zebrafish have emerged as an advantageous model due to their high fecundity, relative ease of genetic manipulation, and transparency during development. Here we summarize studies that have used zebrafish models to study human syndromes that present with both craniofacial and limb phenotypes. We discuss the highly conserved processes of craniofacial and limb/fin development and describe recent zebrafish studies that have explored the function of genes associated with human syndromes with phenotypes in both structures. We attempt to identify commonalities between the two to help explain why craniofacial and limb anomalies often occur together. 相似文献

Background: Limb‐body wall defect is a rare condition characterized by a combination of large and complex defects of the ventral thorax and abdominal wall with craniofacial and limb anomalies. Methods: The aim of this study was to describe the experience of our fetal medicine service, a reference from Southern Brazil, with prenatally diagnosed patients with a limb‐body wall defect in a 3 years period. Only patients who fulfilled the criteria suggested by Hunter et al. (2011) were included in the study. Clinical data and results of radiological and cytogenetic evaluation were collected from their medical records. Results: Our sample was composed of 8 patients. Many of their mothers were younger than 25 years (50%) and in their first pregnancy (62.5%). It is noteworthy that one patient was referred due to suspected anencephaly and another due to a twin pregnancy with an embryonic sac. Craniofacial defects were verified in three patients (37.5%), thoracic/abdominal abnormalities in 6 (75%) and limb defects in eight (100%). Congenital heart defects were observed in five patients (62.5%). One of them presented a previously undescribed complex heart defect. Conclusion: The results disclosed that complementary exams, such as MRI and echocardiography, are important to better define the observed defects. Some of them, such as congenital heart defects, may be more common than previously reported. This definition is essential for the proper management of the pregnancy and genetic counseling of the family. The birth of these children must be planned with caution and for the prognosis a long survival possibility, despite unlikely and rare, must be considered.

We report on a patient with congenital distal limb contractures, characteristic face, prominent metopic sutures, narrow forehead, severe psychomotor and growth retardation, white matter lesions and failure to thrive. The child has many overlapping features with those reported previously by Chitayat. We suggest that the central nervous anomalies are responsible for the congenital contractures in Chitayat syndrome. 相似文献

Anophthalmos with limb anomalies (Waardenburg Opththalmo-Acromelic Syndrome) is a very rare autosomal recessive multiple congenital anomaly syndrome, first described by Waardenburg et al. in 1961 (MIM 206920). It is characterized by mono or more often bilateral anophthalmia/microphthalmia and foot malformations, which can be observed in 91% of the patients. The most common anomaly of the feet is the presence of four toes. The hands are affected bilaterally in 77% of the cases. The most characteristic anomaly is the synostosis of the fourth and fifth metacarpals. To date, 33 cases from 19 families have been reported. We present an Italian case of anophthalmia with limb anomalies and a renal malformation, which has never been described in the literature. 相似文献

In humans, unpaired organs are placed in a highly ordered pattern along the left-right axis. As indicated by animal studies, a cascade of signaling molecules establish left-right asymmetry in the developing embryo. Some of the same genes are involved also in limb patterning. To provide a better insight into the connection between these processes in humans, we analysed the symmetry of limb deficiencies among infants with multiple congenital anomalies. The study was based on data collected by the International Clearinghouse for Birth Defects Monitoring Systems (ICBDMS). Registries of the ICBDMS provided information on infants who, in addition to a limb deficiency, also had at least one major congenital anomaly in other organ systems. We reviewed 815 such cases of which 149 cases (18.3 %) were syndromic and 666 (81.7 %) were nonsyndromic. The comparisons were made within the associated limb deficiencies, considering the information on symmetry, using a comparison group with malformations associated not involved in the index association. Among the non-syndromic cases, the left-right distribution of limb deficiencies did not differ appreciably between limb deficiency subtypes (e.g., preaxial, transverse, longitudinal). The left-right distribution of limb anomalies did not differ among most types of non-limb anomalies, though a predominance of left-sided limb deficiencies was observed in the presence of severe genital defects - odds ratio [OR], 2.6; 95 % CI, 1.1-6.4). Limb deficiencies (LDs) were more often unilateral than bilateral when accompanied by gastroschisis (OR, 0.1) or axial skeletal defects (OR, 0.5). On the contrary, LDs were more often bilateral than unilateral when associated with cleft lip with or without cleft palate (OR, 3.9) or micrognathia (OR, 2.6). Specifically, we found an association between bilateral preaxial deficiencies and cleft lip, bilateral amelia with gastroschisis and urinary tract anomalies, and bilateral transverse deficiencies and gastroschisis and axial skeleton defects. Of 149 syndromic cases, 62 (41.6 %) were diagnosed as trisomy 18. Out of the 30 cases of trisomy 18 with known laterality, 20 cases were bilateral. In the remainder the right and left sides were equally affected. Also, in most cases (74.4 %) only the upper limbs were involved. In conclusion the left-right distribution of limb deficiencies among some non-limb anomalies may suggest a relationship between the development of the limb and the left-right axis of the embryo. 相似文献

OBJECTIVE--To examine genetic and environmental factors in the origin of isolated congenital limb deficiencies. DESIGN--Case-control study with questionnaire at a family interview of cases of isolated congenital limb deficiencies (six types), negative controls (matched for age, sex, and place of residence), and positive controls (cases of sentinel anomalies). SETTING--The database of the Hungarian Congenital Abnormality Registry, 1975-84, complemented by three other sources of ascertainment (1,575,904 births). SUBJECTS--537 case-control pairs; 392 positive controls. MAIN OUTCOME MEASURES--Smoking during pregnancy, congenital limb deficiencies. RESULTS--The adjusted rate of smoking during pregnancy was significantly higher in the mothers of cases of terminal transverse defect (relative odds 1.48; 95% confidence interval 0.98 to 2.23; P = 0.017). This finding supports the hypothesis of vascular disruption as a cause of congenital limb deficiency. CONCLUSIONS--Maternal smoking during pregnancy raises the relative odds for terminal transverse limb deficiencies. 相似文献

Better fit and function of prosthetic limbs is promoted when section and closure is done with attention to the prospective use of the stump as a pad for seating the limb. Preservation of tissue, fixing muscles to bone under physiologic tension, and making sure that bone ends are well covered with tissue are important to the comfort and usefulness of the limb that is to be fitted to the stump. Immediate application of a plaster-cast to form a total-contact socket for seating a temporary prosthetic limb, then early standing, weight-bearing and walking aid in healing and in shaping the stump to the permanent prosthetic socket it will ultimately occupy. 相似文献

We have carried out the third in a series of anatomical dissections of amputated congenitally deformed human limbs in an attempt to determine the etiological relationship between the bony and soft tissue anomalies. This specimen consisted of a limb with congenital tibial aplasia and an adducted foot with five toes. The arterial and nerve patterns were reminiscent of those seen previously by us. The arteries were characterized by absence of the anterior tibial artery and an incomplete plantar arch. The superficial peroneal nerve terminated at the ankle. Extra branches from the sural, deep peroneal, and medial plantar nerves supplied branches to the dorsum of the foot. There were two extra muscles in the leg. The remaining muscles were normal, with the exception that most muscles normally inserting on the plantar surface of the foot inserted instead into a common tendon sheet. The tibia was replaced by a tendinous band, and the talus and calcaneus were united by a complete synchondrosis. The contralateral limb clinically appeared to have a clubfoot. The combination of an absent anterior tibial artery and an incomplete plantar arch is consistent with our theory that a reduced number of vessels puts the embryonic limb at increased risk of congenital defects due to the reduction in the number of collateral blood routes. Some event, such as extravasation of blood or embolization, may concurrently or subsequently compromise blood flow in the remaining vessels. We have previously observed abnormal arterial patterns similar to that described above in limbs having absence of the tibia and in other patients having clubfeet. The presence of abnormal arterial patterns in a limb with absence of the tibia and a contralateral limb with clubfoot suggests that absent tibia and clubfoot may be etiologically related. 相似文献

Background
Data on long-term complications in adult patients with congenital heart disease (ACHD) and a prosthetic valve are scarce. Moreover, the influence of prosthetic valves on quality of life (QoL) and functional outcome in ACHD patients with prosthetic valves has not been studied.Objectives
The primary objective of the PROSTAVA study is to investigate the relation between prosthetic valve characteristics (type, size and location) and functional outcome as well as QoL in ACHD patients. The secondary objectives are to investigate the prevalence and predictors of prosthesis-related complications including prosthesis-patient mismatch.Methods
The PROSTAVA study, a multicentre cross-sectional observational study, will include approximately 550 ACHD patients with prosthetic valves. Primary outcome measures are maximum oxygen uptake during cardiopulmonary exercise testing and QoL. Secondary outcomes are the prevalence and incidence of valve-related complications including prosthesis-patient mismatch. Other evaluations are medical history, physical examination, echocardiography, MRI, rhythm monitoring and laboratory evaluation (including NT-proBNP).Implications
Identification of the relation between prosthetic valve characteristics in ACHD patients on one hand and functional outcome, QoL, the prevalence and predictors of prosthesis-related complications on the other hand may influence the choice of valve prosthesis, the indication for more extensive surgery and the indication for re-operation. 相似文献15.
Ongoing animal preclinical studies on transcutaneous bone-anchored prostheses have aimed to improve biomechanics of prosthetic locomotion in people with limb loss. It is much less common to translate successful developments in human biomechanics and prosthetic research to veterinary medicine to treat animals with limb loss. Current standard of care in veterinary medicine is amputation of the whole limb if a distal segment cannot be salvaged. Bone-anchored transcutaneous prostheses, developed for people with limb loss, could be beneficial for veterinary practice. The aim of this study was to examined if and how cats utilize the limb with a bone-anchored passive transtibial prosthesis during level and slope walking. Four cats were implanted with a porous titanium implant into the right distal tibia. Ground reaction forces and full-body kinematics were recorded during level and slope (±50%) walking before and 4–6 months after implantation and prosthesis attachment. The duty factor of the prosthetic limb exceeded zero in all cats and slope conditions (p < 0.05) and was in the range of 45.0–60.6%. Thus, cats utilized the prosthetic leg for locomotion instead of walking on three legs. Ground reaction forces, power and work of the prosthetic limb were reduced compared to intact locomotion, whereas those of the contralateral hind- and forelimbs increased (p < 0.05). This asymmetry was likely caused by insufficient energy generation for propulsion by the prosthetic leg, as no signs of pain or discomfort were observed in the animals. We concluded that cats could utilize a unilateral bone-anchored transtibial prosthesis for quadrupedal level and slope locomotion. 相似文献

Congenital heart defects are known to be associated with facial dysmorphism and other congenital anomalies. Oculo-facio-cardio-dental (OFCD) syndrome is one such rare multiple congenital anomaly syndrome inherited as an X-linked dominant condition characterized by congenital cataracts, multiple minor facial dysmorphic features, congenital heart defects and dental anomalies. It is unrecognized by many medical and dental professionals. Only 21 cases have been reported so far. This syndrome is often misrecognized as rubella embryopathy because of association of congenital cataract with cardiac anomalies. It is usually the orthodontists who diagnose the syndrome based on typical findings on dental panoramic radiographs. But we suspected our patient to be having OFCD syndrome based on typical facial dysmorphism, ocular and cardiac defects, and finally it was confirmed after noticing typical dental radiographic findings. 相似文献

Heterozygous carriers of an ataxia-telangiectasia (A-T), Fanconi anemia (FA), or xeroderma pigmentosum (XP) gene may be predisposed to some of the same congenital malformations or developmental disabilities that are common among homozygotes. To test this hypothesis, medical records, death certificates, and questionnaires from 27 A-T families, 25 FA families, and 31 XP families were reviewed. Eleven XP blood relatives (out of 1,100) were found with moderate or severe unexplained mental retardation, a significant excess compared to the FA and A-T families (3/1,439). There were four microcephalic XP blood relatives and none in the FA or A-T families. In the A-T families, idiopathic scoliosis and vertebral anomalies were in excess, while genitourinary and distal limb malformations were found in the FA families. A-T, FA, or XP heterozygotes may constitute an important proportion of individuals at risk for specific malformations or developmental abnormalities. 相似文献

Pre-auricular tags are relatively common isolated congenital anomalies with a prevalence of about 5 per 1000 live births. Several associations with congenital anomalies have been reported and the opportunity of systematic ultrasonography examinations in these patients were debated in the literature. We conducted a retrospective epidemiological study on 95 affected newborns, to evaluate whether infants with pre-auricular tags may be at risk for associated anomalies. Our results focus the attention on the increased risk of congenital urinary tract and heart malformations in newborns with isolated pre-auricular tags. Therefore, we recommend that a carefully genetic clinical examination to evaluated dysmorphic features evocative of a specific pattern or syndrome and an urinary and cardiac ultrasonography should be performed in infants with isolated pre-auricular tags. 相似文献
