    In this report, we describe the esophageal atresia in terms of current surgical management on the basis of our experience and literatures. Traditionally, infants with esophageal atresia have presented shortly after birth because of an inability to pass an orogastric tube, respiratory distress, or an inability to tolerate feeding. And also, an isolated trachea-esophageal fistula (TEF) usually cases coughing, recurrent pneumonia, or choking during feedings. To ignore these symptoms is to risk a delayed diagnosis. The condition may be associated with other major congenital anomalies such as those seen in the vertebral, anal, cardiac, tracheo-esophageal, renal/radial (VACTER) association, or it may be an isolated defect. Therapeutic strategies for esophageal atresia are a prevention of pulmonary complication by TEF closing and an early establishment of enteral alimentation. We promptly repair healthy infants without performing a gastrostomy and delay repair in infants with high-risk factors such as associated severe cardiac anomaly and respiratory insufficiency. Esophageal atresia has been classically approached through a thoracotomy. The disadvantages of such a thoracotomy have been recognized for a long time, for example winged scapula, elevation of fixation of shoulder, asymmetry of the chest wall, rib fusion, scoliosis, and breast and pectoral muscle maldevelopment. To avoid such disadvantages, thoracoscopic repair was recently reported.

    The purpose of this study was to show the clinical characteristics of microtia and congenital aural atresia cases in Turkey and to make the classification. For this purpose, records of 28 patients with microtia who were admitted to the ENT Clinic of Eskisehir Military Hospital, Turkey, between 1995 and 2011 and 3 patients admitted to the ENT outpatient clinic of Kocaeli Derince Education and Research Hospital, Turkey, were analyzed retrospectively. Of the total 31 patients with microtia (35 microtic ears), involvement of the right ear of 20 patients (64.5%), the left ear of 7 patients (22.5%), and bilateral involvement in 4 patients (12.9%) were observed. There was a unilateral involvement in 27 patients (87.1%). According to the Marx grading, 2 patients (5.7%) had grade 1 malformation, 3 (8.6%) had grade 2 malformation, 29 (82.9%) had grade 3 malformation, and 1 (2.9%) had grade 4 malformation (anotia). Although the characteristics of microtia vary in different population, the results in Turkey are consistent with those in the literature.

    The association between epidermolysis bullosa (EB) and pyloric atresia (PA) is rare but well documented. Herein, we report a case of EB associated with congenital PA. A female baby, weighing 1480 g, was born vaginally to a 31-year-old gravida 7 lady at 33 weeks of gestation. Polyhydramnios was detected on antenatal assessment. The parents were non-consanguineous Saudis with no family history of significant illness. At birth, well-demarcated areas of peeled skin were present over knees, left leg and periumbilical region. Systemic examination revealed no other abnormality. On second day, the patient developed recurrent vomiting and abdominal distension. An abdominal X-ray revealed a single gastric gas bubble suggesting pyloric obstruction. Following gastroduodenostomy, the baby developed severe sepsis with multiorgan dysfunction and expired on 25th day of life. Skin biopsy showed cleavage within lamina lucida. PMID:24068383

    This is a case report of a three-month-old male who presented to clinic with a cystic lesion under the tongue. On clinical examination, a cystic lesion was observed in the, floor-of-mouth. The patient was referred to Paediatric Otorhinolaryngology service for further management. The differential diagnoses for floor-of-mouth lesions should be reviewed with primary focus on the Wharton’s duct atresia and its management. It is crucial to recognize submandibular duct atresia in the primary Paediatric clinic in order to expedite management of lesion before complications arise including infection, enlargement of cyst, and feeding and breathing difficulties.

    The association of peripheral bronchial atresia and congenital pulmonary airway malformation (CPAM) has recently been recognised, but the pathology of the lesions evolving together has not been described. We present autopsy findings in a 20 week fetus showing areas of peripheral bronchial destruction and airway malformation consistent with developing CPAM in the right lung supporting a causal relationship between these lesions. This fetus also had congenital heart defect, bilateral renal agenesis and syndactyly. We identified another fetus from our autopsy files, with bilateral renal agenesis, similar right sided pulmonary malformation and cardiac defects. Similar bilateral renal agenesis and defects of the heart and lungs are found in wt1(-/-) mice and we have investigated the expression of WT1 in these fetuses. We hypothesise that the cardiac, liver, renal and possibly lung lesions in these two cases may arise due to mesenchymal defects consequent to WT1 misexpression and discuss evidence for this from the scientific literature. We used immunoperoxidase stains to analyse WT1 expression in autopsy hepatic tissue in both fetuses. We also investigated the expression of α-smooth muscle actin (α-SMA), a marker of activated hepatic stellate cells/myofibroblasts, and desmin in hepatic mesenchyme and compare these findings with control fetuses, without congenital malformations. We found reduced WT1 expression in hepatic mesothelium in both fetuses with malformations. There was also increased expression of α-SMA in liver perisinusoidal cells, as seen in the wt1(-/-) mouse model. We therefore propose that abnormality of WT1 signalling may be an underlying factor, as WT1 is expressed in coelomic lining cells from which mesenchyme is derived in many organs.

  8. Long-term respiratory complications of congenital esophageal atresia with or without tracheoesophageal fistula: an update.

    PubMed

    Kovesi, T

    2013-01-01

    Despite early surgical repair, congenital esophageal atresia with or without tracheoesophageal fistula (EA ± TEF) has long-term effects on respiratory and gastrointestinal function. This review updates summarizes research published since 2003 on long-term respiratory complications in patients with a history of EA ± TEF. Pulmonary hypoplasia appears to not be rare in patients with EA ± TEF. Tracheomalacia is common and is associated with respiratory symptoms in childhood. Aspiration, associated with esophageal dysmotility and/or gastroesophageal reflux, may lead to reduced pulmonary function and bronchiectasis. Pulmonary function is generally normal, although lower than in control patients, and restrictive defects tend to be commoner than obstructive defects. Abnormal airway reactivity is common and, along with respiratory symptoms, is associated with atopy. However, the inflammatory profile in EA ± TEF patients based on bronchial biopsies and exhaled nitric oxide differs from typical allergic asthma. Recent studies suggest that in older patients, respiratory symptoms tend to be associated with atopy, but abnormal lung function tends to be associated with gastroesophageal reflux and with chest wall abnormalities. Early detection and management of aspiration may be important to help prevent decrements in pulmonary function and serious long-term complications in EA ± TEF patients.

    Communicating bronchopulmonary foregut malformations are extremely rare congenital malformations, characterized by a communicating fistula between an isolated part of the respiratory system and the esophagus or the stomach. In this article, we present a case of esophageal atresia type C, later diagnosed as a rare form of a communicating bronchopulmonary foregut malformation, an esophageal atresia combined with right main bronchus originating from the lower esophagus. Therapeutic resection of the right lung was complicated by postpneumonectomy syndrome.

    The aim of this study was to observe the effect of a titanium tube on external auditory canal reconstruction in congenital aural atresia and to assess the tube's effectiveness in preventing external canal stenosis or atresia after reconstruction. Reconstruction of the external ear canal with a titanium mesh tube was performed in 16 patients (16 ears) with congenital aural atresia at the First People's Hospital of Foshan. The titanium mesh tube was removed 1 year after surgery. The patients were followed up for 2 years (2 ± 0.3 years), and all of the patients had formed a new external ear canal. There was no local infection, granulation tissue, re-stenosis, or atresia in any of the patients after surgery. All of the patients were content with their newly formed external ear canal. Titanium mesh tubing is safe and effective for reconstruction of the external ear canal during surgery for congenital aural atresia.

    We conducted a prospective study to investigate the abnormalities of the facial nerve canal in patients with congenital aural atresia by computed tomography (CT). Our study population was made up of 99 patients--68 males and 31 females, aged 6 to 22 years (mean: 13.5)--who had unilateral congenital aural atresia without any inner ear malformations. We compared our findings in these patients with those in 50 controls-33 males and 17 females, aged 5 to 22 years (mean: 15.0)-who had normal ears. We classified the congenital aural atresia patients into three groups (A, B, and C) according to their Jahrsdoerfer grading scale score (≥8; 6 or 7; and ≤5, respectively). The course of the facial nerve canal in both the controls and the study patients was determined by temporal bone CT with multiplanar reconstruction. The distances from different parts of the facial nerve canal to surrounding structures were also measured. The course of the facial nerve canal in the normal ears did not vary much, and there were no statistically significant differences according to head side and sex. In groups B and C, the tympanic segment, mastoid segment, and angle of the second genu of the facial nerve canal were all significantly smaller than those of the controls (p < 0.01 in all cases). Statistically, the tympanic segment of the facial nerve canal in patients with congenital aural atresia was downwardly displaced. The mastoid segment of the facial nerve canal in these patients was more anterior than that of the controls. We conclude that congenital aural atresia is often accompanied by abnormalities of the facial nerve canal, especially in the tympanic segment, the mastoid segment, and the second genu. We found that the lower the Jahrsdoerfer score was, the shorter the tympanic segment was and the more forward the mastoid segment was.

    Congenital facial palsy (CFP) is clinically defined as facial palsy of the seventh cranial nerve which is present at birth or shortly thereafter. It is generally considered to be either developmental or acquired in origin. Facial palsy of developmental origin is associated with other anomalies including those of pinna and external auditory canal, which range from mild defects to severe microtia and atresia. We report a 2-day-old male newborn that had right CFP with bilateral anotia and atresia of external auditory canals which is rare. PMID:27857806

    Aural atresia is a rare congenital malformation of the external and middle ear. There are several syndromic associations of this anomaly with those involving the first and second branchial arches. Occurrence of aural atresia with sclerosing skeletal dysplasia is unknown and has never been reported. The co-existence of a sclerosing dysplasia can make the surgical treatment in aural atresia difficult and risky; and the auditory improvement may not be as expected. Moreover, internal auditory canal narrowing and hence sensorineural hearing loss in sclerosing dysplasia might add to the already existing conductive hearing loss in such patients. In this case report we have described an unknown association of bilateral microtia with sclerosing skeletal dysplasia (autosomal dominant osteopetrosis) and clinical implications of these two conditions occurring together leading to a change in the management plan.

    2016-01-01

    Background/Purpose: This study aims to analyze the incidence and type of various associated anomalies among infants with extrahepatic biliary atresia (EHBA), compare their frequency with those quoted in the existing literature and assess their role in the overall management. Materials and Methods: A retrospective study was performed on 137 infants who underwent the Kasai procedure for EHBA during the past 12 years. The medical records were reviewed for the incidence and type of associated anomalies in addition to the details of the management of the EHBA. Results: Of the137 infants, 40 (29.2%) were diagnosed as having 58 anomalies. The majority of patients had presented in the 3rd month of life; mean age was 81 ± 33 days (range = 20-150 days). There were 32 males and 8 females; boys with EHBA had a higher incidence of associated anomalies. Of these 40 patients, 22 (37.9%) had vascular anomalies, 13 patients (22.4%) had hernias (umbilical-10, inguinal-3), 7 patients (12.1%) had intestinal malrotation, 4 patients (6.8%) had choledochal cyst, 1 patient (1.7%) had Meckel's diverticulum, 3 patients (5%) had undergone prior treatment for jejunoileal atresias (jejunal-2, ileal-1), 2 patients (3.4%) had undergone prior treatment for esophageal atresia and tracheoesophageal fistula, 2 patients (3.4%) had spleniculi, and 2 patients (3.4%) were diagnosed as having situs inversus. Conclusions: The most common associated anomalies in our study were related to the vascular variation at the porta hepatis and the digestive system. The existence of anomalies in distantly developing anatomic regions in patients with EHBA supports the possibility of a “generalized” insult during embryogenesis rather than a “localized” defect. In addition, male infants were observed to have significantly more associated anomalies as compared with the female infants in contrast to earlier reports. PMID:26862288

Congenital esophageal atresia was successfully treated surgically in infancy with the thoracoscopic method. The potential coeliac disease was detected in the child with a correct histopathological examination of intestinal villi and showing no enteropathy symptoms based on the presence of antibodies against tissue transglutaminase and against endomysial antibodies of smooth muscles in serum and the presence of HLA DQ2.5. In the treatment of the potential coeliac disease the girl followed a gluten-free diet.

    Background In our institutional experience treating pediatric choledochal cysts over the last 12 years, we noted 7/32 patients (21.9%) had comorbid congenital cardiac anomalies. This association has not been previously described other than in isolated case reports. We aimed to quantify this association on a national level. Materials and Methods We queried the 2009 Healthcare Cost and Utilization Project Kids' Inpatient Database. Patients with a diagnosis of choledochal cyst (ICD-9-CM 75169, 75162, 75160) or biliary atresia (75161) were identified. Cardiac anomalies were defined using the Clinical Classification Software code (CCS 213). Comorbid choledochal cysts or biliary atresia and congenital cardiac anomalies were quantified in both infant (<12 mos) and child (1–18 yrs) subpopulations. Results Of 1,646 estimated discharges for patients with choledochal cysts, 506 (30.7%) were for patients who also had congenital cardiac anomalies, compared to 2.6% in the general hospitalized population (χ2, p<0.0001). The frequency of congenital cardiac anomalies was lower in 1,973 hospitalizations for biliary atresia (13.8%) than in those for patients with choledochal cysts (χ2, p<0.0001). Cardiac anomalies were detected in 44.9% of choledochal cyst hospitalizations for infants <12 months (vs. 3.44% general hospitalized population; χ2, p<0.0001), but in 6.9% of for children ages 1–18 yrs (vs. 1.3% general hospitalized population; χ2, p<0.0001). Conclusions A strong association was observed between pediatric choledochal cysts and congenital cardiac anomalies that more commonly manifests in infancy. When choledochal cysts are diagnosed either prenatally or in infancy, we suggest echocardiographic screening for cardiac anomalies, which may impact timing of surgery and anesthetic planning.

    Because of the deletion of a segment of the chromosome during the formation of a ring, several clinical findings may be associated with ring chromosomes. Ring chromosome 13 is one of such disorders in which the genotype-phenotype correlation is stronger by virtue of the accumulating literature. It can be associated with multiple congenital abnormalities and severe mental retardation. We report a case with mosaic ring chromosome 13 whose prenatal ultrasound revealed bilateral ventriculomegaly. Anal atresia, unidentifiable external genitalia, and an absent thumb were observed in the postmortem examination.

    This report describes a girl with congenital pouch colon (CPC), uterus didelphys with septate vagina, and a cloacal anomaly. The girl underwent cloacal reconstruction at the age of 15 months. Subsequently, at puberty, the child had primary amenorrhea with severe cyclic abdominal pain due to endometriosis of both the uteruses and adnexal cysts with hematometra and hematosalpinx. Laparotomy with removal of both uteri and the left fallopian tube was performed. Both uteri had atresia of the cervix uteri. This report emphasizes the need for comprehensive evaluation and a long-term management strategy for associated gynecologic anomalies in girls with CPC, especially with regard to patency of the outflow tract.

She spontaneously achieved pregnancy after four years of uterovaginal anastomosis. Gestation was at the eighth lunar month and the delivery was done by cesarean section due to rapidly progressing fetal asphyxia. The patient gave birth to a live healthy male, weighing 1,950 g, with an Apgar score of 5 and 8 at 1 and 5 min, respectively. The postoperative course was uneventful, and leakage of lochia was normal.

    OBJECTIVE--To investigate the efficacy and safety of transcatheter laser-assisted valve dilatation for atretic valves in children with congenital heart disease. DESIGN--Prospective clinical study. SETTING--Supraregional paediatric cardiology centre. SUBJECTS--Eleven children (aged 1 day-11 years; weight 2.1-35.7 kg) with atresia of pulmonary (10) or tricuspid (one) valve underwent attempted laser-assisted valve dilatation as part of the staged treatment of their cyanotic heart disease. INTERVENTION--After delineating the atretic valve by angiography and/or echocardiography a 0.018 inch "hot tip" laser wire was used to perforate the atretic valve. Subsequently the valve was dilated with conventional balloon dilatation catheters up to the valve annulus diameter. RESULTS--Laser-assisted valve dilatation was successfully accomplished in nine children. In two neonates with pulmonary valve atresia, intact ventricular septum, and coexistent infundibular atresia the procedure resulted in cardiac tamponade: one died immediately and one later at surgery. During a follow up of 1-17 months (mean 11) two infants with pulmonary valve atresia and intact ventricular septum died (one with congestive cardiac failure). The remainder are either well palliated and do not require further procedures (three), or are awaiting further transcatheter or surgical procedures because of associated defects (four). CONCLUSIONS--Laser-assisted valve dilatation is a promising adjunct to surgery in this high risk group of patients. It may avoid surgery in some patients, and may reduce the number of surgical procedures in those requiring staged operations. Images PMID:8343325

    2007-04-01

    A nine-month-old Labrador retriever was referred to the Clinica Veterinaria Privata San Marco because of frequent headshaking and downward turning of the right ear. Clinical examination revealed that there was no external acoustic meatus in the right ear. Computed tomography confirmed that the vertical part of the right auditory canal ended blindly, providing a diagnosis of external auditory canal atresia. Cytological examination and culture of fluid from the canal and the bulla revealed only aseptic cerumen; for this reason, it was assumed that the dog was probably affected by a congenital developmental deformity of the external auditory canal. Reconstructive surgery was performed using a "pull-through" technique. Four months after surgery the cosmetic and functional results were satisfactory.

    Congenital bronchial stenosis is rarely described and is difficult to manage. Here we report two cases of right intermediate bronchial stenosis (stenotic orifice with complete cartilage rings). Both cases were associated with ventricular septal defects, and a "trifurcation" pattern was found in both carinas. Both patients underwent surgical repair of the ventricular septal defects but could not be separated from ventilator support despite successful cardiac operations. Slide tracheobronchial plasty was applied to the right intermediate bronchus and lower trachea. After correction of the bronchial stenosis, both patients could be extubated and live without supplementary ventilation support.

    We described a case of congenital atresia of the anterior nares with a minute opening on the right side and underdevelopment of the nasal cavities. The hard palate was flat and the soft palate was normally mobile. Right anophthalmia and microphthalmia of the left eye with iris coloboma were also noted. In order to provide a nasal airway and to enable the newborn to suck and breathe simultaneously the patient was operated on at four days of age. By means of transpalatal approach a nasal cavity was drilled out of solid bone and connected with the small anterior duct. Trough the new created air duct a nasopharyngeal tube was introduced. In spite of that the external nasal orifice was enlarged later, there was an inclination the orifice to collapse due to lack of nostril cartilages, therefore a nasopharyngeal tube still is used. The physical and intellectual development of the now 11-month old infant is normal. Final reconstruction of the external nose will take place later.

    Background Ongoing studies using genomic microarrays and next-generation sequencing have demonstrated that the genetic contributions to cardiovascular diseases have been significantly ignored in the past. The aim of this study was to identify rare copy number variants in individuals with congenital pulmonary atresia (PA). Methods and Results Based on the hypothesis that rare structural variants encompassing key genes play an important role in heart development in PA patients, we performed high-resolution genome-wide microarrays for copy number variations (CNVs) in 82 PA patient-parent trios and 189 controls with an Illumina SNP array platform. CNVs were identified in 17/82 patients (20.7%), and eight of these CNVs (9.8%) are considered potentially pathogenic. Five de novo CNVs occurred at two known congenital heart disease (CHD) loci (16p13.1 and 22q11.2). Two de novo CNVs that may affect folate and vitamin B12 metabolism were identified for the first time. A de novo 1-Mb deletion at 17p13.2 may represent a rare genomic disorder that involves mild intellectual disability and associated facial features. Conclusions Rare CNVs contribute to the pathogenesis of PA (9.8%), suggesting that the causes of PA are heterogeneous and pleiotropic. Together with previous data from animal models, our results might help identify a link between CHD and folate-mediated one-carbon metabolism (FOCM). With the accumulation of high-resolution SNP array data, these previously undescribed rare CNVs may help reveal critical gene(s) in CHD and may provide novel insights about CHD pathogenesis.

    Purpose: A rare but described risk factor for deep venous thrombosis (DVT), predominately in the young, is congenital agenesis or atresia of the inferior vena cava (IVC). The optimal management for DVT in this subset of patients is unknown. We evaluated the efficacy of pharmacomechanical catheter-directed thrombolysis (PCDT) followed by systemic anticoagulation in the treatment of acute lower-extremity DVT in the setting of congenital IVC agenesis or atresia. Materials and Methods: Between November of 2005 and May of 2010, six patients (three women [average age 21 years]) were referred to our department with acute lower-extremity DVT and subsequently found to have IVC agenesis or atresia on magnetic resonance imaging. A standardized technique for PCDT (the Angiojet Rheolytic Thrombectomy System followed by the EKOS Microsonic Accelerated Thrombolysis System) was used for all subjects. Successful thrombolysis was followed by systemic heparinization with transition to Coumadin or low molecular-weight heparin and compression stockings. Subjects were followed-up at 1, 3, and then every 6 months after the procedure with clinical assessment and bilateral lower-extremity venous ultrasound. Results: All PCDT procedures were technically successful. No venous stenting or angioplasty was performed. The average thrombolysis time was 28.6 h (range 12-72). Two patients experienced heparin-induced thrombocytopenia, and one patient developed a self-limited knee hemarthrosis, No patients were lost to follow-up. The average length of follow-up was 25.8 {+-} 20.2 months (range 3.8-54.8). No incidence of recurrent DVT was identified. There were no manifestations of postthrombotic syndrome. Conclusions: PCDT followed by systemic anticoagulation and the use of compression stockings appears to be safe and effective in relatively long-term follow-up treatment of patients who present with acute DVT and IVC agenesis or atresia.

    Objective: The aim of this study was to introduce a new technique which is combined laparoscopic and vaginal cervicovaginal reconstruction using split thickness skin graft in patients with congenital atresia of cervix and to evaluate the feasibility and the safety of it. Methods: This is a prospective observational study of 10 patients with congenital atresia of cervix who underwent combined laparoscopic and vaginal cervicovaginal reconstruction using split thickness skin graft for cervicovaginal reconstruction from February 2013 to August 2014 in our hospital. All of the surgical procedures were carried out by the same operation team. Patient data were collected including operating time, estimated blood loss, hospital stay post-surgery, complications, total cost, and median vaginal length at 3 month, resumption of menstruation, vaginal stenosis and stricture of the cervix postoperatively. Results: The operative procedure lasted 237±46 (175-380) min. The estimated blood loss was 160±76 (50-300) ml. The hospital stay post-surgery was 12±2 (9-18) days. None of the patients had complications or required a blood transfusion. The mean total cost was $3352±1025. The average vaginal length at 3 month was 8.3±1.1 (8-10) cm. All patients had resumption of menstruation. The patients were followed for a mean of 5±2 (1-10) months. Cervical or vaginal stenosis did not occur in any of the patients. Conclusions: Our experiences of combined laparoscopic and vaginal cervicovaginal reconstruction using split thickness skin graft in10 patients with congenital atresia of cervix were positive, with successful results and without complications, and cervical or vaginal stenosis.

    Ureteral atresia is a rare disease usually associated with a non-functioning dysplastic kidney. The condition may be unilateral or bilateral; focal, short or long and may involve any part of the ureter. Association with other urinary anomalies is rare. We report the case of a 10-month-old boy with prenatal diagnosis of multicystic right kidney. This suspicion was confirmed after birth by ultrasound and static scintigraphy; a right vesicoureteral reflux (VUR) was recorded at cystography. The boy presented a regular renal function but was hospitalized twice for suspected pyelonephritis between the 8th and the 10th month of life and were recorded occasional mild changes in blood pressure. Antibiotic prophylaxis was administered until surgery. When he was 10-month underwent retroperitoneoscopy to perform a nephroureterectomy finding a complete atresia of the upper third of the ureter with the blind end at the level of the uretero-pelvic-junction. The programmed surgery was performed. By a revision of literature, only few cases of imperforate distal ureter have been described. This condition is associated with a kidney dysplasia. The atresia of the ureter with no signs of infection in the dysplastic kidney may be unknown up to adulthood or throughout one's life. Prognosis usually depends on the severity of the obstruction.

    To investigate whether differences existing in the distance between facial nerve (FN) and round window niche opening among congenital aural atresia (CAA), congenital aural stenosis (CAS) and a normal control group and to assess its effect on the round window implantation of vibrant soundbridge, CT images of 10 normal subjects (20 ears), 27 CAS patients (30 ears) and 25 CAA patients (30 ears) were analyzed. The distances from the central point of round window niche opening to the terminal point of the horizontal segment, the salient point of pyramidal segment, the beginning point of the vertical segment, and the vertical segment of the facial nerve (abbreviate as OA, OB, OC, OE, respectively) were calculated based on three-dimensional reconstruction using mimics software. The results suggested that the pyramidal segment of the FN was positioned more closely to round window niche opening in patients with both CAA and CAS groups than that in control group, whereas there was no significant difference between CAA and CAS group (P < 0.05). The vertical portion of the FN was positioned more closely to round window niche opening in the CAA group than those in both the CAS and control groups with statistical significance (P < 0.05). Furthermore, the vertical portion of the FN was positioned more closely to round window niche opening in the CAS group than that in control group (P < 0.05). In conclusion, the dislocation between facial nerve and round window niche in patients with congenital auditory canal malformations could have significant effects on the round window implantation of vibrant soundbridge. Moreover, three-dimensional measurements and assessments before surgery might be helpful for a safer surgical approach and implantation of vibrant soundbridge.

    We report on the molecular characterization of a microdeletion of approximately 2.5Mb at 2p11.2 in a female baby with left congenital aural atresia, microtia, and ipsilateral internal carotid artery agenesis. The deletion was characterized by fluorescence in situ hybridization, array comparative genomic hybridization, and whole genome re-sequencing. Among the genes present in the deleted region, we focused our attention on the FOXI3 gene. Foxi3 is a member of the Foxi class of Forkhead transcription factors. In mouse, chicken and zebrafish Foxi3 homologues are expressed in the ectoderm and endoderm giving rise to elements of the jaw as well as external, middle and inner ear. Homozygous Foxi3−/− mice have recently been generated and show a complete absence of the inner, middle, and external ears as well as severe defects in the jaw and palate. Recently, a 7-bp duplication within exon 1 of FOXI3 that produces a frameshift and a premature stop codon was found in hairless dogs. Mild malformations of the outer auditory canal (closed ear canal) and ear lobe have also been noted in a fraction of FOXI3 heterozygote Peruvian hairless dogs. Based on the phenotypes of Foxi3 mutant animals, we propose that FOXI3 may be responsible for the phenotypic features of our patient. Further characterization of the genomic region and the analysis of similar patients may help to demonstrate this point. PMID:25655429

    Both of congenital giant RCA, RCA to PA fistula, and CLMCA-A are one of exceedingly rare vascular abnormalities. We present the case of a 34-year-old man with multiple congenital coronary anomalies above, and a successful surgical intervention was proceeded for our patient.This is a case of a 34-year-old man presented with apical systolic murmur and exertional chest pain. Furthermore, a dilated left heart and abnormal pulmonary blood flow was observed in this patient. Coronary CTA and selective CAG showed a 15-mm diameter RCA with a fistula to pulmonary trunk and CLMCA-A. During cardiac surgery, the coronary abnormalities were confirmed and the outlet of the fistula was closed. After surgery, less chest pain, respiratory infection, and left heart failure were observed in this patient.This case illustrates that the surgery of closing the fistula between the giant RCA and pulmonary trunk could improve the symptoms and signs for this patient. It could be predicted that simplified operation could be a promising therapy for patient with giant RCA to PA fistula and CLMCA-A. Moreover, CABG should be taken full account of when myocardial ischemia was found in the blood-supply area of LAD.

    Bronchial asthma is one of the most common maternal diseases complicating pregnancy. We assessed the risks of congenital abnormalities in a case-control population-based analysis using the dataset of the Hungarian Case-Control Surveillance of Congenital Abnormalities between 1980 and 1996. Of the 22,843 cases with congenital abnormalities, 511 (2.2%) had mothers with bronchial asthma, while of the 38,151 matched control subjects without congenital abnormalities 757 (2.0%) had mothers with bronchial asthma (unadjusted prevalence odds ratios [POR] 1.2; 95% CI: 1.0-1.3). In all mothers with bronchial asthma, a higher incidence of respiratory tract infections and higher drug intake could be observed. In the case group of medically recorded bronchial asthma, a slightly increased risk for club foot has been revealed. However, this weak association could be explained by the higher proportion of preterm births in this group. The main limitation of the analysis was that at the time of data collection only a small proportion of pregnant mothers were using anti-asthma medications recommended by the actual guidelines.

    Rectal atresia and anal stenosis are rare forms of anorectal malformations. The aim of the definitive surgical repair in such cases is to preserve the anal canal, the dentate line, and the sphincter complex. We present a case of rectal atresia and anal stenosis to demonstrate the differences in the operative repair. The techniques described leave the anterior wall of the very distal anal canal untouched in both rectal stenosis and anal atresia; however, the dissection of the rectum differs. The atretic rectum in rectal atresia is mobilized and sutured to the anal canal circumferentially. In anal stenosis, the posterior rectum is mobilized in the form of rectal advancement, and the posterior 180° is anastomosed directly to the skin (as in a standard PSARP) with preservation of the anal canal as the anterior 180° of the final anoplasty. These patients have an excellent prognosis for bowel control and fecal continence, and therefore, complete mobilization and resection of the anal canal must be avoided.

    Congenital high airway obstruction syndrome (CHAOS) from laryngeal atresia bears a poor prognosis for hydropic fetuses owing to cardiac failure. We attempted percutaneous fetoscopic and ultrasound-guided tracheal decompression in a hydropic human fetus with CHAOS associated with Fraser syndrome. Percutaneous fetoscopic and ultrasound-guided tracheal decompression was performed using three trocars under general materno-fetal anesthesia at 19 + 5 weeks of gestation. Abnormal fetoplacental blood flow normalized within hours as a result of the intervention. Furthermore, a normalization of lung : heart size and lung echogenicity was observed within days. Resolution of hydrops was complete within 3 weeks. Premature rupture of membranes and premature contractions prompted emergency delivery of the fetus by ex-utero intrapartum treatment (EXIT) at 28 + 2 weeks of gestation. Following delivery, the lungs could be ventilated at low pressures and ambient oxygen concentration. Weaning from ventilation was achieved at 18 days of postnatal life. Our experience indicated that percutaneous fetoscopic and ultrasound-guided decompression of the fetal trachea is feasible and may permit normalization of hemodynamics in hydropic human fetuses with CHAOS from laryngeal atresia. The procedure may also result in normalization of heart : lung size and provide the time needed to regain the function of the overstretched diaphragm in this grave fetal condition.

    In a 27-year-old patient with cyclic hematuria a complex congenital malformation was diagnosed: the atresia of the upper third of the vagina and the external uterine cervix, a vesico-uterine fistula, and agenesis of the right kidney. The patient was treated surgically in two phases: first, the vesico-uterine fistula was closed abdominally and then, vaginally, the cervix was lowered down to its normal anatomic site and the external cervical orifice was opened. The postoperative course was normal and the patient was discharged from hospital 20 days after surgery. After 2 months the findings of the follow-up examination were normal, and so were the menstrual cycle and urination.

    We describe a 14-year-old boy with congenital bilateral cataracts, blepharophimosis, ptosis, choanal atresia, sensorineural hearing loss, short, webbed neck, poor esophageal motility, severe growth and mental retardation, skeletal anomalies, seizures, and no speech. As an infant, he had transient hypogammaglobulinemia requiring IVIG therapy. Cytogenetic studies show an apparently de novo visible duplication at 1p36.3. Fluorescence in situ hybridization (FISH) studies confirm that the common region for the 1p36 deletion syndrome (p58) is duplicated. Probes for D1Z2 at 1p36.3 and the subtelomeric region of 1p (TEL1p) are also duplicated. Array comparative genomic hybridization (aCGH) studies were done at three separate laboratories, each with somewhat different results. BAC whole genome array CGH suggests a single clone gain at the 1p terminus and a single clone deletion at 1p36.3. A targeted BAC array panel with higher resolution at the distal 1p36 region detects a telomeric duplication and an interstitial deletion. Oligonucleotide whole genomic aCGH shows the highest resolution and a more complex rearrangement: two duplications, an interstitial deletion, and a normal region. The MMP23A/B "matrix metalloproteinase 23A/B" genes are within the distal duplication region in our patient, and this patient does not have craniosynostosis. This is the first association of congenital cataracts, choanal atresia, and transient immune abnormalities with 1p36 duplication/deletion. This case illustrates the limitations of different cytogenetic technologies, and shows how three separate aCGH platforms allow for refined delineation and interpretation of the complex cytogenetic rearrangement which would not have been discovered by standard high-resolution chromosome analysis.

    Congenital absence of portal vein is a rare anomaly that results from aberrant venous development in early embryonic life. The intestinal and splenic venous drainage bypass the liver and may drain directly into inferior vena cava or the left renal vein or the left hepatic vein. This rare anomaly is commonly associated with other congenital malformations and generally limited to females. We describe a rare case of aberrant portal vein development with congenital portocaval shunt (end-to-side) in a 3.5-year male child associated with cardiac defects (atrial and ventricular septal defects), skeletal deformities (flexion deformity and clinodactyly of digits and toes), and lichen planus with café au lait macules of skin.

    Anorectal malformation (ARM) is one of the most common congenital anomaly that requires emergency surgery in the neonatal period. ARMs are frequently associated with other life threatening congenital anomalies. Commonly associated anomalies are genito-urinary, cardiovascular, gastro-intestinal, skeletal and spinal. Alimentary tract anomalies are frequently masked by the intestinal obstruction produced by the anorectal atresia. This retrospective study was carried out to find out the incidence of associated alimentary tract atresias with ARM. In our series, out of 785 cases of high ARM, 14 cases had associated esophageal atresia (1.8%), followed by 7 cases of duodenal atresia (0.89%), and followed by pyloric atresia, jejuno-ileal atresia and colonic atresia.

    Congenital recto-urogenital type fistulas with a normal anus and rectal atresia, represent both anorectal malformations that are infrequently seen in clinical practice. We describe the case of a girl with an association of these two anomalies, together with a double vagina who, on her seventh day of life, expelled feces through her genitals. The malformations were corrected by means of a posterior sagittal approach, descending from the rectum to the anus without perineal dissection. The vaginal septum was resected thru the vulva. There is no evidence of recurrence of the recto-vaginal fistula.

    We studied the characteristics of the rhythmicity of heart rate (HR), body temperature (BT), locomotor activity (LA) and autonomic nervous activity in bronchial-hypersensitive (BHS) and bronchial-hyposensitive (BHR) guinea pigs. For this purpose, HR, BT, LA, and electrocardiogram (ECG) were recorded from conscious and unrestrained guinea pigs using a telemetry system. Autonomic nervous activity was analyzed by power spectral analysis of heart rate variability. Nocturnal patterns, in which the values in the dark phase (20:00-06:00) were higher than those in the light phase (06:00-20:00), were observed in HR, BT and LA in both strains of guinea pigs. The autonomic nervous activity in BHS guinea pigs showed a daily pattern, although BHR guinea pigs did not show such a rhythmicity. The high frequency (HF) power in BHS guinea pigs was higher than that in BHR guinea pigs throughout the day. Moreover, the low frequency/high frequency (LF/HF) ratio in BHS guinea pigs was lower than that in BHR guinea pigs throughout the day. These results suggest that parasympathetic nervous activity may be predominant in BHS guinea pigs.

    Polysplenia syndrome is a rare malformation characterized by the association of multiple rates and other congenital anomalies dominated by cardiac, vascular, intestinal and bile malformations. We report the observation of a patient operated in the neonatal period (3 days) for an upper intestinal obstruction with situs inversus. Surgical exploration noted the presence of multiple rates, a preduodenal vein, a biliary atresia and a duodenal atresia. The surgical procedures performed were a latero-lateral duodeno-duodenostomy and hepatoportoenterostomy of KASAI with simple immediate and delayed outcomes. The follow up was of 23 years. We recall the epidemiological characteristics of this malformative association and we discuss the role played by the prognosis of polysplenia syndrome in the evolution of biliary atresia. The diagnosis and treatment of biliary atresia are always urgent to increase the chances of success of the Kasai, and the chances of prolonged survival with native liver. However, almost all long-term survivors (even anicteric) have biliary cirrhosis, which requires lifelong follow up.

    Extrahepatic biliary atresia (EHBA), an inflammatory sclerosing cholangiopathy, is the leading indication for liver transplantation in children. The cause is still unknown, although possible infectious, genetic, and immunologic etiologies have received much recent focus. These theories are often dependent on each other for secondary or coexisting mechanisms. Concern for EHBA is raised by a cholestatic infant, but the differential diagnosis is large and the path to diagnosis remains varied. Current treatment is surgical with an overall survival rate of approximately 90%. The goals of this article are to review the important clinical aspects of EHBA and to highlight some of the more recent scientific and clinical developments contributing to our understanding of this condition.

    Biliary atresia (BA) is a rare disease characterised by a biliary obstruction of unknown origin that presents in the neonatal period. It is the most frequent surgical cause of cholestatic jaundice in this age group. BA occurs in approximately 1/18,000 live births in Western Europe. In the world, the reported incidence varies from 5/100,000 to 32/100,000 live births, and is highest in Asia and the Pacific region. Females are affected slightly more often than males. The common histopathological picture is one of inflammatory damage to the intra- and extrahepatic bile ducts with sclerosis and narrowing or even obliteration of the biliary tree. Untreated, this condition leads to cirrhosis and death within the first years of life. BA is not known to be a hereditary condition. No primary medical treatment is relevant for the management of BA. Once BA suspected, surgical intervention (Kasai portoenterostomy) should be performed as soon as possible as operations performed early in life is more likely to be successful. Liver transplantation may be needed later if the Kasai operation fails to restore the biliary flow or if cirrhotic complications occur. At present, approximately 90% of BA patients survive and the majority have normal quality of life. PMID:16872500

    Background Esophageal atresia with or without tracheoesophageal fistula (EA/TEF) represents the most common developmental malformation of the upper digestive tract. It is classified into six subtypes according to the classification of Vogt, depending on anatomical variation of this malformation. Around 50% of the patients with EA/TEF present additional anomalies, which often influence, next to the EA/TEF subtype, the overall prognosis of EA/TEF newborns. Here, we investigated the association of the different EA/TEF subtypes with co-occurring congenital anomalies in EA/TEF patients and demonstrate their implications for postnatal diagnostic workup. Materials and Methods We investigated 333 patients of a large German multicenter study born between 1980 and 2012. After evaluation of all available clinical records, 235 patients were included in our analysis. We compared our results with existing data. Results The highest risk for co-occurring anomalies was seen in patients with most common Vogt 3b (p = 0.024), especially for additional gastrointestinal anomalies (p = 0.04). Co-occurring anomalies of the skin were significantly more common in patients with subtype Vogt 2 (p = 0.024). A significant correlation was observed for an impaired neurodevelopmental outcome and EA/TEF Vogt 3a (p = 0.041). Patients with EA/TEF showed a higher risk to present with any additional congenital anomaly compared with the general population (p < 0.001). Conclusion Our results warrant thorough clinical workup for gastrointestinal anomalies especially in patients with Vogt 3b. Moreover, it might be necessary to focus on a thorough aftercare for neurocognitive development in patients with Vogt 3a. The here presented observations need to be confirmed by future studies.

    Oesophageal atresia is a congenital developmental defect of alimentary tract concerning the interruption of oesophagus with or without connection with the trachea. The incidence of oesophageal atresia is 1:3000-3500 of live-born infants. Associated anomalies occur in 50% of patients (syndromic cases). In the rest of the patients with oesophageal atresia these anomalies are isolated (non-syndromic cases). The knowledge of dysmorphic syndromes with oesophageal defects, allows us to diagnose the complex genetic syndromes and to implement the correct treatment and correct genetic counselling concerning the etiology, natural course of the disease, prognosis and possible complications as well as determining the recurrence risk of the disease in the family. The authors describe the chosen embryological, epidemiological and genetic aspects of congenital oesophageal atresia. The clinical aspects, genetic counselling as well as the genetic basis of chosen genetic syndromes with oesophageal atresia are also described in this article.

    Objective—To compare the atrial and ventricular myoarchitecture in the normal heart and the heart with tricuspid atresia, and to investigate changes in the three dimensional arrangement of collagen fibrils.
Methods—Blunt dissection and cell maceration with scanning electron microscopy were used to study the architecture of the atrial and ventricular musculature and the arrangement of collagen fibrils in three specimens with tricuspid atresia and six normal human hearts.
Results—There were significant modifications in the myoarchitecture of the right atrium and the left ventricle, both being noticeably hypertrophied. The middle layer of the ventricle in the abnormal hearts was thicker than in the normal hearts. The orientation of the superficial layer in the left ventricle in hearts with tricuspid atresia was irregular compared with the normal hearts. Scanning electron microscopy showed coarser endomysial sheaths and denser perimysial septa in hearts with tricuspid atresia than in normal hearts.
Conclusions—The overall architecture of the muscle fibres and its connective tissue matrix in hearts with tricuspid atresia differed from normal, probably reflecting modelling of the myocardium that is inherent to the malformation. This is in concordance with clinical observations showing deterioration in pump function of the dominant left ventricle from very early in life.

    Esophageal atresia (EA) with or without tracheoesophageal fistula (TEF) is the most common congenital anomaly of the esophagus. The improvement of survival observed over the previous two decades is multifactorial and largely attributable to advances in neonatal intensive care, neonatal anesthesia, ventilatory and nutritional support, antibiotics, early surgical intervention, surgical materials and techniques. Indeed, mortality is currently limited to those cases with coexisting severe life-threatening anomalies. The diagnosis of EA is most commonly made during the first 24 h of life but may occur either antenatally or may be delayed. The primary surgical correction for EA and TEF is the best option in the absence of severe malformations. There is no ideal replacement for the esophagus and the optimal surgical treatment for patients with long-gap EA is still controversial. The primary complications during the postoperative period are leak and stenosis of the anastomosis, gastro-esophageal reflux, esophageal dysmotility, fistula recurrence, respiratory disorders and deformities of the thoracic wall. Data regarding long-term outcomes and follow-ups are limited for patients following EA/TEF repair. The determination of the risk factors for the complicated evolution following EA/TEF repair may positively impact long-term prognoses. Much remains to be studied regarding this condition. This manuscript provides a literature review of the current knowledge regarding EA. PMID:22851858

  18. Prenatal presentation and postnatal management of congenital thoracic malformations.

    PubMed

    Bush, Andrew

    2009-11-01

    The antenatal finding of a congenital thoracic malformation (CTM) leads to anxiety in the parents and uncertainty as to the optimal management. The antenatal spectrum of CTM includes congenital cystic adenomatoid malformation, sequestration, congenital lobar emphysema, enteric and bronchogenic cysts, and bronchial atresia. Most lesions require no antenatal intervention, and shrink substantially in the third trimester, but if fetal hydrops develops, then antenatal intervention is required, occasionally medical but more usually surgical, because mortality is high. If the baby is symptomatic in the newborn period, then some form of surgical intervention is clearly required. The asymptomatic baby presents a therapeutic dilemma. Advocates of early surgery point to the complications of CTM, which include infection, pneumothorax, bleeding and malignant transformation. Those who are proponents of conservative management retort that some CTM disappear postnatally, and that the complication rate is unknown; many children appear never to need surgery. Furthermore, there is clearcut evidence that excision of a CTM does not totally eliminate the risk of a subsequent malignancy. It is clear that, both antenatally and postnatally, counselling of the family on a case by case basis is needed. The limitations of present evidence should be stressed. Different families will make different decisions about postnatal surgery in an asymptomatic baby. If surgery is performed, morbidity is low, particularly with a video-assisted thoracoscopic (VATS) procedure.

    The preceding pages have described an organism that is far removed from mammals on the taxonomic scale of vertebrates but one that has proven to have a unique and most useful system for studies of liver function and, in particular, bile product transport and excretion. It is also an organism in which iron loading can be studied in the liver and other organs and tissues. Many of the events that occur in this animal during its life cycle with regard to bile pigment metabolism as normal programmed phenomena are unparalleled among the vertebrates. In the larval (ammocoete) period of lampreys, there is an intrahepatic gallbladder and a biliary tree that is well equipped for the storage, transport, and elimination of bile products into the intestine for ultimate excretion with the feces. The importance of the patency of these bile ducts to bile excretion is illustrated in one species of lampreys in which the bile ducts of young ammocoetes become infested with larval nematodes to a degree that bile pigment regurgitation into the blood results in a green serum that is identified as biliverdin. Despite having serum levels of biliverdin that would be toxic to humans, these individuals live a complete larval life. The larvae of all lamprey species undergo a phase of metamorphosis in which they transform into adults. During this phase the larval gallbladder, the bile canaliculi of the hepatocytes, and all the intrahepatic bile ducts completely regress in a developmental process called lamprey biliary atresia. The epithelium of the extrahepatic common bile duct transforms and expands into a caudal portion of the endocrine pancreas of the adult. Many of the events of lamprey biliary atresia resemble events occurring during experimental and pathological conditions of mammalian cholestasis, including disruption to the bile-blood barrier (intercellular junctions), accumulation of bile components in the cytoplasmic inclusions, and alteration of the distribution of membrane enzymes

    Congenital aural atresia is the failure of development of the external auditory canal. It usually occurs in conjunction with microtia, which is the malformation of the auricle due to a failure of development of the external ear. Aural atresia, with or without microtia, may significantly affect the hearing and social life of the patients. It is important for every medical practitioner to be aware of the possible treatment options for hearing rehabilitation in this group of patients. In the era of modern technology, new choices, including Bone-Anchored Hearing Aid (BAHA) (Cochlear Ltd. and Oticon Medical), Vibrant Soundbridge (VSB) (MED-EL, Innsbruck, Austria), and Bonebridge system (BB) (MED-EL, Innsbruck, Austria), provide high-end alternatives to traditional Bone Conduction Hearing Aid and Auditory Canal Reconstruction. All these options have advantages and disadvantages, and they are appropriate for different patients and/or at different ages. This paper aims to provide an overview of the management of hearing rehabilitation in congenital aural atresia patients and a discussion of each treatment option. PMID:24883324

    Biliary atresia is the most common cause of pediatric end-stage liver disease and the leading indication for pediatric liver transplantation. Affected infants exhibit evidence of biliary obstruction within the first few weeks after birth. Early diagnosis and successful surgical drainage of bile are associated with greater survival with the child's native liver. Unfortunately, because noncholestatic jaundice is extremely common in early infancy, it is difficult to identify the rare infant with cholestatic jaundice who has biliary atresia. Hence, the need for timely diagnosis of this disease warrants a discussion of the feasibility of screening for biliary atresia to improve outcomes. Herein, newborn screening for biliary atresia in the United States is assessed by using criteria established by the Discretionary Advisory Committee on Heritable Disorders in Newborns and Children. Published analyses indicate that newborn screening for biliary atresia by using serum bilirubin concentrations or stool color cards is potentially life-saving and cost-effective. Further studies are necessary to evaluate the feasibility, effectiveness, and costs of potential screening strategies for early identification of biliary atresia in the United States.

    Asthma, by definition is a variable disease. When there is more than normal natural variation in airflow, asthma can be provoked by a wide range of stimuli that include infectious, allergic, and environmental agents. Bronchoconstriction determines much of the short-term variability in airflow that characterizes asthma. Current treatments do not redress the excess smooth muscle mass that is present in the remodeled airway in chronic asthma. Thus, it is intriguing to consider the potential contribution of bronchial thermoplasty (a procedure that involves controlled heat treatment to reduce the mass of the airway smooth muscle) as an effective therapy for poorly controlled asthma.

    Congenital duodenal atresia complicated by gastric perforation (GP) is a very rare and a very mortal condition. Only three newborns could be cured in the reported 13 cases. We report a successfully treated newborn with this complicated disease. A 2-day-old male was hospitalized with prediagnosis of duodenal obstruction. Twelve hours later, significant abdominal distention occurred promptly. At laparotomy, GP and preampullary duodenal atresia were detected. Gastrorrhaphy and duodenoduodenostomy were performed in the same operation. The patient was discharged on the 15th postoperative day. This complicated disease can be treated by early diagnosis and surgical intervention. We choose one-stage operation because of the clean peritoneal cavity. However, generalized peritonitis may require two-stage operation in delayed cases.

    Biliary atresia (BA) is the major cause of cholestasis and the leading indication for liver transplantation (LT). However, the incidence of BA in Korea has not been reported. The aim of this study was to investigate the incidence and clinical outcomes of BA in Korea. We used the Korean universal health insurance database and extracted data regarding BA patients younger than 18 years of age admitted between 2011 and 2015. The incidence of BA was calculated by dividing the number of BA patients by the number of live births. Two hundred forty infants were newly diagnosed with BA. A total of 963 BA patients younger than 18 years of age were followed up for 5 years. The overall incidence of BA was 1.06 cases per 10,000 live births. The incidence of BA was 1.4 times higher for female patients than for male patients. Additionally, significant seasonal variation was observed; in particular, the incidence of BA was 2 times higher from June through August than from December through February. Congenital anomalies were found in 38 of 240 patients (15.8%). Congenital heart diseases were major associated congenital anomalies (6.3%). Several complications developed during the study period, including cholangitis (24.0%), varix (6.2%), and gastrointestinal bleeding (4.4%). Three hundred and one of the 963 BA patients under 18 years of age (31.3%) received LT for BA. The incidence of BA is higher in Korea than that in Western countries. We also report significant gender-associated differences and seasonal variation with respect to the incidence of BA. PMID:28244293

    A 9-year-old boy with congenital atresia of the left main coronary artery underwent myocardial revascularization. Coarctation of the aorta and ventricular septal defect were diagnosed at the age of 1 year. At age 7 years, the child presented with syncope while exercising. Preoperative evaluation included cardiac catheterization which revealed the unexpected finding of congenital atresia of the left main coronary artery with origin of the circumflex artery from the right coronary artery. Surgical correction included myocardial revascularization by means of left internal mammary artery graft to the anterior descending coronary artery, coarctation resection, and ventricular septal defect repair. The patient recovered uneventfully. We report the details of this extremely rare case with successful concomitant surgical management of the congenital coronary artery anomaly and the associated structural heart disease.

    We encountered a rare case of gastroschisis associated with jejunal atresia and colonic atresia. In our case, the jejunal atresia was not discovered for 27 days after the initial abdominal wall closure. The colonic atresia was not discovered for 48 days after initial repair of the gastroschisis secondary to the rarity of the disorder. Both types of atresia were repaired with primary hand-sewn anastomoses. Other than the prolonged parenteral nutrition and hyperbilirubinemia, our patient did very well throughout his hospital course. Based on our case presentation, small bowel atresia and colonic atresia must be considered in patients who undergo abdominal wall closure for gastroschisis with prolonged symptoms suggestive of bowel obstruction. Our case report also demonstrates primary enteric anastomosis as a safe, well-tolerated surgical option for patients with types of intestinal atresia. PMID:26180651

    Congenital biliary atresia is an incurable disease of newborn infants, of unknown genetic causes, that results in congenital deformation of the gallbladder and biliary duct system. Here, we show that during mouse organogenesis, insufficient SOX17 expression in the gallbladder and bile duct epithelia results in congenital biliary atresia and subsequent acute ‘embryonic hepatitis’, leading to perinatal death in ~95% of the Sox17 heterozygote neonates in C57BL/6 (B6) background mice. During gallbladder and bile duct development, Sox17 was expressed at the distal edge of the gallbladder primordium. In the Sox17+/− B6 embryos, gallbladder epithelia were hypoplastic, and some were detached from the luminal wall, leading to bile duct stenosis or atresia. The shredding of the gallbladder epithelia is probably caused by cell-autonomous defects in proliferation and maintenance of the Sox17+/− gallbladder/bile duct epithelia. Our results suggest that Sox17 plays a dosage-dependent function in the morphogenesis and maturation of gallbladder and bile duct epithelia during the late-organogenic stages, highlighting a novel entry point to the understanding of the etiology and pathogenesis of human congenital biliary atresia.

    Although tracheal stenosis and bronchial stenosis are relatively rare in the pediatric population, they are both associated with significant morbidity and mortality. While most cases of congenital tracheal stenosis in children present as complete tracheal rings (CTRs), other congenital tracheal obstructions are also encountered in clinical practice. In addition, acquired obstructive tracheal conditions stemming from endotracheal trauma or previous surgical interventions may occur. Many affected children also have associated cardiovascular malformations, further complicating their management. Optimal management of children with tracheal or bronchial stenoses requires comprehensive diagnostic evaluation and optimization prior to surgery. Slide tracheoplasty has been the operative intervention of choice in the treatment of the majority of these children. PMID:28066618

    Fusion of the atlas with the occipital bone is a rare congenital dysplasia known as occipitalization of the atlas, occipitocervical synostosis, assimilation of the atlas, or atlanto-occipital fusion. It is a component of the paraxial mesodermal maldevelopment and commonly associated with other dysplasias of the craniovertebral junction. External auditory canal atresia or external aural atresia is a rare congenital absence of the external auditory canal. It occurs as the consequence of the maldevelopment of the first pharyngeal cleft due to defects of cranial neural crest cells migration and/or differentiation. It is commonly associated with the dysplasias of the structures derived from the first and second pharyngeal arches including microtia. We present the coexistence of the occipitalization of the atlas and congenital aural atresia, an uncommon combination of the paraxial mesodermal maldevelopment, and defects of cranial neural crest cells. The association is most probably syndromic as minimal diagnostic criteria for the oculoariculovertebral spectrum are fulfilled. From the clinical point of view, it is important to be aware that patients with microtia must obtain also appropriate diagnostic imaging studies of the craniovetebral junction due to eventual concomitant occipitalization of the atlas and frequently associated C1-C2 instability.

    A total of 116 cases of intestinal atresia or stenosis were encountered at the Yale-New Haven Hospital between 1970 and 1990. Sites involved were the duodenum (n = 61; 53%), jejunum or ileum (n = 47; 46%), and colon (n = 8; 7%). All but two patients underwent operative correction, for an overall survival rate of 92%. Challenging problems were the management of apple-peel atresia (five patients), multiple intestinal atresia with short-gut syndrome (eight patients), and proximal jejunal atresia with megaduodenum requiring imbrication duodenoplasty (four patients). Major assets in the improved outlook for intestinal atresia are prenatal diagnosis, regionalization of neonatal care, improved recognition of associated conditions, innovative surgical methods, and uncomplicated long-term total parenteral nutrition.

    The assessment of echographic features of biliary atresia was conducted in 65 newborn children ageing up to 3 mo. Their characteristic variants were revealed: the absence or reduction in size of gall-bladder, the presence of hyperechogenic triangular formation in V. portae bifurcation (the symptom of "triangular cicatrix"); the thickening of anterior wall of V. portae right branch. The timely and correct establishment of the diagnosis permits a child to survive and serve the hepatic fibrosis prophylaxis. Echohepatography is a sufficiently trustful method of investigation.

    Objective: To evaluate the presentation, management, complications and outcome of intestinal atresia (IA) managed at our center over a period of 1 year. Materials and methods: Records of patients of IA admitted in our center from January 2015 to December 2015 were retrospectively analyzed. Demographic data, antenatal history, presenting complaints, location (duodenal, jejunoileal, colonic) of atresia, surgery performed and peri-operative complications were noted. Results: Total 78 cases of IA were included in the analyses. Mean age and weight at the time of presentation was 5.8 days (range 0-50), and 1.9 kg (range 1.1-3.2), respectively. IA included duodenal atresia [DA (32)], jejuno-ileal atresia [JIA (40)], colonic atresia [CA (3)] and atresia at multiple-location (sites) in 3 cases. Ninety percent of patients underwent surgery within 5 to 20 hours of admission. All cases of DA except one underwent Kimura's diamond shaped duodeno-duodenostomy. One case with perforated duodenal web underwent duodenotomy with excision of web. Seven patients with JIA and CA required primary stoma, while rest were managed by excision of dilated proximal segment and primary anastomosis. Complications included anastomotic leak in 5, proximal perforation in 2, functional obstruction in 7, aspiration pneumonitis in 3, and wound infection in 6 patients. Mean hospital stay for survivors was 11 days. Overall survival was 63%. Conclusion: Late presentation, overcrowding in intensive care unit, septicemia, functional obstruction and anastomotic leak are the causes of poor outcome in our series. Early diagnosis, some modification in surgical technique, use of total parenteral nutrition and adequate investigations for other congenital anomalies may improve the outcome. PMID:27896159

    Trisomy 18 is one of the congenital disorders caused by a chromosomal abnormality. Ninety percent of fetuses with trisomy 18 have various other malformations. The present patient had heart failure due to a complex cardiac malformation and a Gross C type esophageal atresia. Before the esophageal banding, ventilation of the lungs was impossible and respiratory condition was unstable. Considering that direction of the shunt can easily change by hyperventilation and high oxygen concentration, we employed the lowest oxygen concentration and ventilation as possible. In the present case, it was necessary to provide respiratory care for both esophageal atresia and complex cardiac malformation.

    Congenital aural atresia (CAA) poses significant challenges to surgical remediation. Both bone anchored hearing aids (BAHA) and the Vibrant Soundbridge (VSB) have been considered as alternatives or adjuncts to conventional atresiaplasty. A consensus statement on VSB implantation in children and adolescents recommended against implantation when the Jahrsdoerfer score was less than 8. More recent publications suggest that patients with Jahrsdoerfer scores between three and seven may benefit from VSB implantation. The purpose of this study was to further investigate the outcomes of VSB implantation in CAA. The study was a multi-center, retrospective review. A retrospective review of data (patient's demographic, clinical, implant and audiological information) from four collaborating centers that have performed VSB implantation in CAA was performed. Outcomes based on severity of the atresia using the Jahrsdoerfer and Yellon-Branstetter scoring systems were also evaluated. Data from 28 patients from the four centers revealed no iatrogenic facial nerve injuries or change in bone thresholds. Post-operative speech threshold and speech recognition was, respectively, 39 dB and 94%. Jahrsdoerfer and Yellon scores ranged from 4 to 9 and 4 to 12, respectively. The scores did not correlate to or predict outcomes. Three individual elements of the scores did correlate to initial, but not long-term outcomes. Atresiaplasty and BAHA in the management of CAA are not complete solutions. VSB may offer an alternative in these surgically complex patients for achieving amplification, though better metrics for patient selection need to be developed. LEVEL OF EVIDENCE : IV.

  5. Intestinal obstruction due to dual gastrointestinal atresia in infants: diagnosis and management of 3 cases

    PubMed Central

    2014-01-01

    Background Several types of congenital lesions can cause complete or incomplete obstruction of the intestine. Our purpose is to present 3 neonates with dual intestinal type I atresia, i.e., simultaneous obstructive lesions at 2 locations in which the atresia manifested as diaphragm-like tissue. Case presentation All 3 cases were female infants ranging in age from 2 to 14 months. The common symptom in all cases was intermittent persistent vomiting. In some cases the vomitus was bilious, and other symptoms included abdominal distention and delayed meconium passage. Prior surgeries at another hospital were unsuccessful at relieving the symptoms in one case. One case had dual lesions in the colon, one dual lesions in the duodenum, and one atresia at both the distal portion of the ileum and the descending colon. Surgical exploration and removal of the lesions at our hospital was successful in all cases, and the infants were discharged in good condition. Conclusions Type I atresia can manifest as a diaphragm-like tissue obstructing the continuity of gastrointestinal tract, and in rare cases multiple areas may be present. Base on the intermittent nature of the associated symptoms, diagnosis can be difficult and is often delayed. Physicians should be aware of this condition during the work-up of an infant with persistent intermittent vomiting. PMID:24928109

    Bronchial carcinoids are uncommon pulmonary neoplasms and represent 1 to 2 % of all lung tumors. In early stage of disease, the mainstay and only curative treatment is surgery. Bronchial carcinoids are generally regarded as low-grade carcinomas and metastatic dissemination is unusual. The management of the metastatic stage is not currently standardized due to a lack of relevant studies. As bronchial carcinoids and in particular their metastatic forms are rare, we apply treatment strategies that have been evaluated in gastrointestinal and pancreatic neuroendocrine tumors. However, bronchial carcinoids have their own characteristic. A specific therapeutic feature of these metastatic tumors is that they require a dual approach: both anti-secretory for the carcinoid syndrome, and anti-tumoral.

    The association of congenital tracheal stenosis and tracheoesophageal (TE) fistula is rare. Here, we report 2 patients with tracheobronchial stenosis (complete cartilage ring) involving the lower trachea and right bronchus. Both patients had associated VACTERL (vertebral anomalies, anal atresia, cardiovascular anomalies, TE, renal, and limb defects) congenital cardiac defects and tracheal diverticula after repair of the TE fistula in type C esophageal atresia. The stenotic segment began at the orifice of the TE fistula, which became diverticula after the TE fistula was repaired. Concomitant repair of congenital cardiac defects and a slide tracheoplasty with elimination of the diverticula were performed successfully.

However, investigations available help to point towards the correct diagnosis in reasonable time frame. Imaging by Sonography has identified several parameters which can be of utility in the diagnostic work up. Comparison of Sonography with imaging by Nuclear medicine can bring out the significant differences and also help in appropriate imaging. The battery of Biochemical tests, available currently, enable better understanding of the line-up of investigations in a given child with neonatal cholestasis. Management protocols enable standardized care with optimal outcome. The place of surgical management in biliary atresia is undisputed, although Kasai procedure and primary liver transplantation have been pitted against each other.

    The clinical features of 41 infants with various types of nasal obstruction were reviewed to study the correlation between the degree of nasal obstruction and clinical manifestations. Twenty-one subjects had bilateral choanal atresia/stenosis; 12 had unilateral choanal atresia/stenosis, and eight who were referred with suspected choanal atresia had a simple inflammatory nasal obstruction. Patients with bilateral choanal obstruction and patients with unilateral choanal obstruction or rhinitis showed no differences in clinical picture or in referral age. Many infants with either unilateral or bilateral choanal obstruction had one or more symptoms not fully relieved after surgical repair, although the choanae were widely patent. At long-term follow-up the surviving patients showed spontaneous recovery and good nasal respiration. Overall, five patients died. Since the common syndrome appeared to be related to a dysfunction of the autonomic nervous system, we conclude that any type of nasal obstruction may exacerbate or precipitate an underlying maturational autonomic disturbance.

    Anorectal malformations (ARMs) commonly co-occur with other congenital anomalies, particularly VACTERL (vertebral, anorectal, cardiac, tracheal, esophageal, renal, limb, and duodenal) associations. However, this collection of associations is not comprehensive, and other concurrent anomalies may exist that can be missed during the standard work-up of patients with ARMs. We present a rare case of a neonate with a low ARM with concurrent jejuno-ileal atresia that was diagnosed after the correction of the ARM when the patient developed segmental volvulus. This case illustrates the importance of having a high index of suspicion when deviation from a classic presentation occurs. PMID:27896167

    Biliary atresia is the most common cause of end-stage liver disease in the infant and is the leading pediatric indication for liver transplantation in the United States. Earlier diagnosis (<30-45 days of life) is associated with improved outcomes following the Kasai portoenterostomy and longer survival with the native liver. However, establishing this diagnosis is problematic because of its rarity, the much more common indirect hyperbilirubinemia that occurs in the newborn period, and the schedule for routine infant health care visits in the United States. The pathogenesis of biliary atresia appears to involve immune-mediated fibro-obliteration of the extrahepatic and intrahepatic biliary tree in most patients and defective morphogenesis of the biliary system in the remainder. The determinants of the outcome of portoenterostomy include the age at surgery, the center's experience, the presence of associated congenital anomalies, and the postoperative occurrence of cholangitis. A number of screening strategies in infants have been studied. The most promising are early measurements of serum conjugated bilirubin and a stool color card given to new parents that alerts them and their primary care provider to acholic stools. This report summarizes a National Institutes of Health workshop held on September 12 and 13, 2006, in Bethesda, MD, that addressed the issues of outcomes, screening, and pathogenesis of biliary atresia.

    Atresia of the aortic arch is a rare congenital heart defect with a high mortality when associated with other intracardiac defects. Cardiac magnetic resonance (CMR) provides the exact anatomy of the aortic arch and collateral circulation and is useful to diagnose-associated aortic arch anomalies. This report describes the case of a 4-year-old child with atresia of the aortic arch, referred to our institution with the diagnosis of aortic coarctation and bicuspid aortic valve. On clinical exam, the femoral pulses were not palpable and there was a significant differential blood pressure between the upper and lower limbs. The echocardiography showed a severely stenotic bicuspid aortic valve but was limited for the exact description of the aortic arch. CMR showed absence of lumen continuity between the ascending and descending aorta distal to the left subclavian artery, extending over 5 mm, with the presence of a bend in the arch and diverticulum on either side of the zone of discontinuity, suggesting the diagnosis atresia of the aortic arch rather than coarctation or interruption. The patient benefited from a successful surgical commissurotomy of the aortic valve and reconstruction of the aortic arch with a homograft. The post-operative CMR confirmed the good surgical result. This case emphasizes the utility of CMR to provide good anatomical information to establish the exact diagnosis and the operative strategy. PMID:25853109

    We report on two familial cases from a non-consanguineous marriage, presenting multiple intestinal and choanal atresia. Massive hydramnios and dilatation of the bowel were observed at 29 weeks of gestation during routine ultrasound scan of a healthy mother. The fetal karyotype was normal and cystic fibrosis screening was negative. Regular scans were performed throughout the pregnancy. The child was born at 34 weeks gestation. Choanal atresia was diagnosed at birth and abdominal investigations showed multiple atresia interesting both the small bowel and the colon. Further interventions were necessary because of recurrent obstructions. During the following pregnancy, a dilatation of the fetal intestinal tract was detected by ultrasonography at 27 weeks of gestation. Pregnancy was interrupted. Post-mortem examination of the fetus confirmed the stenosis of long segments of the small intestine associated with areas of colonic atresia. In both cases, histology and distribution were consistent with those reported in hereditary multiple intestinal atresia (HMIA). An association between multiple intestinal and choanal atresia has never been reported. We suggest it could correspond to a new autosomal recessive entity for which cytogenetic investigations and high-resolution array CGH revealed no visible anomalies.

    Isolated left subclavian artery is one of the rarer aortic arch anomalies. It has been associated with other congenital heart diseases, typically tetralogy of Fallot, double-outlet right ventricle, and atrial and ventricular septal defects. Its significant clinical implications include a left-to-right shunt from the vertebrobasilar system, which causes pulmonary overcirculation and subclavian steal. We present an unusual case of a premature infant who was diagnosed prenatally with congenital complete atrioventricular block and tricuspid atresia and was found to have an isolated left subclavian artery postnatally. The patient underwent implantation of a permanent single-chamber epicardial pacing system. To our knowledge, this combination of lesions has not been reported—and in our case, it influenced our surgical planning. PMID:28100981

    The aim of this pilot study was to determine the acceptance and benefit from the middle ear implant system Vibrant Soundbridge(®) (VSB, MED-EL Corporation, Austria) by means of a questionnaire, compared to a previously used conventional bone conducting hearing device, in preschool children with unilateral congenital aural atresia. Prospective cohort study. All nine children with unilateral congenital aural atresia used the VSB and had previous experience with a bone conducting hearing device. The benefit from the VSB was evaluated by questionnaires concerning acceptance of hearing aids, handling, listening effort, behavior, quality of life, and the duration of daily use and compared to the experience with the bone conducting hearing device. In addition, to quantify the benefit from the VSB use, audiological assessment (pure-tone audiometry via free field testing, speech audiometry, and localization test) was performed with and without VSB. The questionnaires and audiological test results were compared pairwise. According to all questionnaire areas, children benefited significantly more from the VSB compared to bone conducting hearing device (ps <.05). The most important finding was a significant increase in daily use from 2 h for the bone conducting hearing device to 10 h for the VSB. Children performed significantly better with the VSB than without it in the audiological assessment. Children with unilateral aural atresia benefited significantly more from the VSB compared to a conventional bone conducting hearing device according to the parents' questionnaires and yielded better results in the audiometry and localization test with the VSB than without it.

    2013-01-01

    Background Intestinal atresia is a rare congenital disorder with an incidence of 3/10 000 birth. About one-third of patients have severe intestinal dysfunction after surgical repair. We examined whether prenatal gastrointestinal obstruction might effect on the myenteric plexus and account for subsequent functional disorders. Methodology/Principal Findings We studied a rat model of surgically induced antenatal atresia, comparing intestinal samples from both sides of the obstruction and with healthy rat pups controls. Whole-mount preparations of the myenteric plexus were stained for choline acetyltransferase (ChAT) and nitric oxide synthase (nNOS). Quantitative reverse transcription PCR was used to analyze mRNAs for inflammatory markers. Functional motility and permeability analyses were performed in vitro. Phenotypic studies were also performed in 8 newborns with intestinal atresia. In the experimental model, the proportion of nNOS-immunoreactive neurons was similar in proximal and distal segments (6.7±4.6% vs 5.6±4.2%, p = 0.25), but proximal segments contained a higher proportion of ChAT-immunoreactive neurons (13.2±6.2% vs 7.5±4.3%, p = 0.005). Phenotypic changes were associated with a 100-fold lower concentration-dependent contractile response to carbachol and a 1.6-fold higher EFS-induced contractile response in proximal compared to distal segments. Transcellular (p = 0.002) but not paracellular permeability was increased. Comparison with controls showed that modifications involved not only proximal but also distal segments. Phenotypic studies in human atresia confirmed the changes in ChAT expression. Conclusion Experimental atresia in fetal rat induces differential myenteric plexus phenotypical as well as functional changes (motility and permeability) between the two sides of the obstruction. Delineating these changes might help to identify markers predictive of motility dysfunction and to define guidelines for post-surgical care. PMID:23667464

    AIM: To investigate the spatial distribution patterns of anorectal atresia/stenosis in China. METHODS: Data were collected from the Chinese Birth Defects Monitoring Network (CBDMN), a hospital-based congenital malformations registry system. All fetuses more than 28 wk of gestation and neonates up to 7 d of age in hospitals within the monitoring sites of the CBDMN were monitored from 2001 to 2005. Two-dimensional graph-theoretical clustering was used to divide monitoring sites of the CBDMN into different clusters according to the average incidences of anorectal atresia/stenosis in the different monitoring sites. RESULTS: The overall average incidence of anorectal atresia/stenosis in China was 3.17 per 10 000 from 2001 to 2005. The areas with the highest average incidences of anorectal atresia/stenosis were almost always focused in Eastern China. The monitoring sites were grouped into 6 clusters of areas. Cluster 1 comprised the monitoring sites in Heilongjiang Province, Jilin Province, and Liaoning Province; Cluster 2 was composed of those in Fujian Province, Guangdong Province, Hainan Province, Guangxi Zhuang Autonomous Region, south Hunan Province, and south Jiangxi Province; Cluster 3 consisted of those in Beijing Municipal City, Tianjin Municipal City, Hebei Province, Shandong Province, north Jiangsu Province, and north Anhui Province; Cluster 4 was made up of those in Zhejiang Province, Shanghai Municipal City, south Anhui Province, south Jiangsu Province, north Hunan Province, north Jiangxi Province, Hubei Province, Henan Province, Shanxi Province and Inner Mongolia Autonomous Region; Cluster 5 consisted of those in Ningxia Hui Autonomous Region, Gansu Province and Qinghai Province; and Cluster 6 included those in Shaanxi Province, Sichuan Province, Chongqing Municipal City, Yunnan Province, Guizhou Province, Xinjiang Uygur Autonomous Province and Tibet Autonomous Region.

    1998-01-01

    The history of bronchial asthma from ancient times is traced. The first accounts of asthma in the ancient Greeks and Romans with clinical descriptions by Aretus of Cappadocia and Aulus Celsus Cornelius are recounted. These are followed by the medieval habits of the Middle East as described by Moises Maimonides. The Renaissance is witness to a new scientific fervor in postulating theories on the pathogenesis of bronchial asthma by van Helmont, Willis and Floyer. The seventeenth and eighteenth centuries will see the discovery of the anatomical foundation of bronchial asthma thanks largely to the technical advances in the diagnostic field by Auerbrugge and Laennec. The allergic nature of bronchial asthma is studied by Salter. S Meltzer's hypothesis of histamine release as the pathogenesis of bronchial asthma leads the way for the twentieth century's leading discoveries.

Previous methods for assessing bronchial morphology, however, are unsuited to the very young patient. To assess bronchial morphology, 100 consecutive patients under 18 months of age (medium 57.5 days) with suspected congenital heart disease were studied by high kilovoltage filtered beam radiographs, before cardiac catheterisation. This low radiation dose technique clearly defined bronchial anatomy in 95 patients. The lengths of the left and right main bronchi were compared and 10 cases (10%) had a ratio less than 1.5 suggesting bronchial isomerism. Discriminant function analysis based on tracheal width and bronchial length enabled clear distinction of right from left bronchi. Four patients had bilateral right and six had bilateral left bronchi. Four of these 10 cases died and had necropsy confirmation of the radiological diagnosis. Practical prediction about cardiac anatomy, particularly the systemic and pulmonary venous return, may be made when bronchial morphology is known. Images PMID:7437200

  16. Biliary atresia: From Australia to the zebrafish.

    PubMed

    Davenport, Mark

    2016-02-01

    This review is based upon an invited lecture for the 52nd Annual Meeting of the British Association of Paediatric Surgeons, July 2015. The aetiology of biliary atresia (BA) is at best obscure, but it is probable that a number of causes or pathophysiological mechanisms may be involved leading to the final common phenotype we recognise clinically. By way of illustration, similar conditions to human BA are described, including biliary agenesis, which is the normal state and peculiar final pattern of bile duct development in the jawless fish, the lamprey. Furthermore, there have been remarkable outbreaks in the Australian outback of BA in newborn lambs whose mothers were exposed to and grazed upon a particular plant species (Dysphania glomulifera) during gestation. More recent work using a zebrafish model has isolated a toxic isoflavonoid, now named Biliatresone, thought to be responsible for these outbreaks. Normal development of the bile ducts is reviewed and parallels drawn with two clinical variants thought to definitively have their origins in intrauterine life: Biliary Atresia Splenic Malformation syndrome (BASM) and Cystic Biliary Atresia (CBA). For both variants there is sufficient clinical evidence, including associated anomalies and antenatal detection, respectively, to warrant their aetiological attribution as developmental BA. CMV IgM +ve associated BA is a further variant that appears separate with distinct clinical, histological, and immunohistochemical features. In these it seems possible that this involves perinatal obliteration of a normally formed duct system. Although still circumstantial, this evidence appears convincing enough to perhaps warrant a different treatment strategy. This then still leaves the most common (more than 60% in Western series) variant, now termed Isolated BA, whereby origins can only be alluded to.

    It is encouraging that we are improving the technical aspects of treatment modalities for biliary atresia. However, it is clear that more needs to be done to best develop new treatment plans while applying the modalities we have (porto-enterostomy or liver transplantation or both) in a way that will afford the best survival and quality-of-life. This review article will discuss a number of points that are vital to improving care and illustrates the need to further scrutinize treatment decisions.

    Esophageal atresia (EA) is defined as a discontinuity of the lumen of the esophagus repaired soon after birth. Dysphagia is a common symptom in these patients, usually related to stricture, dysmotility or peptic esophagitis. We present 4 cases of patients with EA who complained of dysphagia and the diagnosis of Eosinophilic esophagitis (EoE) was made, ages ranging from 9 to 16 years. Although our patients were on acid suppression years after their EA repair, they presented with acute worsening of dysphagia. Esophogastroduodenoscopy and/or barium swallow did not show stricture and biopsies revealed elevated eosinophil counts consistent with EoE. Two of 4 patients improved symptomatically with the topical steroids. It is important to note that all our patients have asthma and 3 out of 4 have tested positive for food allergies. One of our patients developed recurrent anastomotic strictures that improved with the treatment of the EoE. A previous case report linked the recurrence of esophageal strictures in patients with EA repair with EoE. Once the EoE was treated the strictures resolved. On the other hand, based on our observation, EoE could be present in patients without recurrent anastomotic strictures. There appears to be a spectrum in the disease process. We are suggesting that EoE is a frequent concomitant problem in patients with history of congenital esophageal deformities, and for this reason any of these patients with refractory reflux symptoms or dysphagia (with or without anastomotic stricture) may benefit from an endoscopic evaluation with biopsies to rule out EoE.

    In childhood, the surgical treatment of gastroesophageal reflux is the main cause of dumping syndrome. We report the cases of 2 children with esophageal atresia who presented with dumping syndrome without any precipitating known factors, such as gastroesophageal reflux surgery or associated microgastria. Our data suggest (1) that dumping syndrome can occur after primary anastomosis of esophageal atresia without antireflux surgery and (2) that dumping syndrome should be considered in every child treated surgically for esophageal atresia presenting with digestive symptoms, malaise, failure to thrive, or refusal to eat.

    Historically, congenital pulmonary lymphangiectasia (CPL) has had poor treatment outcomes despite aggressive therapy. There are recent reports of ethiodized oil (Lipiodol) lymphangiography successfully treating lymphatic leakage in adults. In this report, we describe two infants with CPL complicated by chylothoraces successfully treated by instillation of ethiodized oil into the lymphatic system. Congenital atresia of the thoracic duct was demonstrated on the lymphangiogram in both patients before treatment. Both patients have shown good short-term outcomes without supplemental oxygen or fat restricted diets at 9 months of age. Ethiodized oil lymphangiography represents a new treatment modality for some patients with CPL.

    Down syndrome (DS) is the most common congenital anomaly widely studied for at least 150 years. However, the type and the frequency of congenital anomalies associated with DS are still controversial. Despite prenatal diagnosis and elective termination of pregnancy for fetal anomalies, in Europe, from 2008 to 2012 the live birth prevalence of DS per 10,000 was 10. 2. The objectives of this study were to examine the major congenital anomalies occurring in infants and fetuses with Down syndrome. The material for this study came from 402,532 consecutive pregnancies of known outcome registered by our registry of congenital anomalies between 1979 and 2008. Four hundred sixty seven (64%) out of the 728 cases with DS registered had at least one major associated congenital anomaly. The most common associated anomalies were cardiac anomalies, 323 cases (44%), followed by digestive system anomalies, 42 cases (6%), musculoskeletal system anomalies, 35 cases (5%), urinary system anomalies, 28 cases (4%), respiratory system anomalies, 13 cases (2%), and other system anomalies, 26 cases (3.6%). Among the cases with DS with congenital heart defects, the most common cardiac anomaly was atrioventricular septal defect (30%) followed by atrial septum defect (25%), ventricular septal defect (22%), patent ductus arteriosus (5%), coarctation of aorta (5%), and tetralogy of Fallot (3%). Among the cases with DS with a digestive system anomaly recorded, duodenal atresia (67%), Hirschsprung disease (14%), and tracheo-esophageal atresia (10%) were the most common. Fourteen (2%) of the cases with DS had an obstructive anomaly of the renal pelvis, including hydronephrosis. The other most common anomalies associated with cases with DS were syndactyly, club foot, polydactyly, limb reduction, cataract, hydrocephaly, cleft palate, hypospadias and diaphragmatic hernia. Many studies to assess the anomalies associated with DS have reported various results. There is no agreement in the literature as to

    A close anatomical and functional relationship between superior and inferior airways is well documented. A typical example is offered by the close relationship between allergic rhinitis and asthma whose close connection is documented by epidemiological and pathological data. The mechanisms which can explain this phenomenon are not fully known but naso-bronchial reflexes, mouth-breathing due to nasal obstruction and aspiration of nasal secretions seem all to be important. Moreover it has been recently proved that the treatment of rhinitis can improve the concomitant asthma thus confirming their relationship. Another less frequent association is between sinusitis and asthma. Such a connection seems to be frequent in patients suffering of atopic rhinitis but also in patients presenting a nasal obstruction of different nature such as deviations of the nasal septum, adenoid hypertrophy etc. Also in this case a correct medical or surgical treatment of sinusitis can improve asthma symptomathology. Finally a classic example of involvement of superior and inferior airways is represented by the syndrome of ASA intolerance. These patients in fact initially complain of rhinitis which afterwards is complicated by the onset of nasal polyposis and asthma which can prove clinically very severe. Nowadays, anyway, there is no evidence that the treatment of rhinitis or polypectomy can improve the clinical course of asthma. In conclusion, diseases of superior and inferior airways must be considered in strict connection and need the same global treatment.

  5. Follicular atresia in the prepubertal spiny mouse (Acomys cahirinus) ovary.

    Hułas-Stasiak, Monika; Gawron, Antoni

    2011-10-01

    This study was designed to determine follicular atresia in the newborn and the prepubertal spiny mouse. We analyzed the processes of follicle loss using classical markers of apoptosis (TUNEL reaction, active caspase-3) and autophagy (Lamp1). Numerous small clear vacuoles and autophagosomes as well as strong Lamp1 staining were observed in dying oocytes of all follicle types, especially of the primordial and primary ones. Active caspase 3 and the TUNEL reaction were detected only in the granulosa cells of large secondary and antral follicles. The expression of apoptosis and autophagy markers was also changing during the prepubertal period. Western blot analysis indicated that at the moment of birth, females undergo an increased rate of follicular atresia mediated by autophagy, while apoptosis is the dominant form of ovarian atresia in consecutive postnatal days. On the basis of these observations, we concluded that apoptosis and autophagy are involved in follicular atresia and these processes are cell and developmental stage-specific.

    Boull, Christina; Maguiness, Sheilagh M

    2016-09-01

    Congenital hemangiomas are rare solitary vascular tumors that do not proliferate after birth. They are characterized as either rapidly involuting congenital hemangiomas (RICHs) or noninvoluting congenital hemangiomas (NICHs) based on their clinical progression. NICHs have no associated complications, but are persistent. RICH, while usually asymptomatic, may ulcerate or bleed early in their presentation, but involute quickly during the first few months of life. Hepatic RICHs are not associated with cutaneous RICHs, but may result in high-output cardiac failure due to arteriovenous or portovenous shunting. In the following review, the clinical characteristics and current management specific to congenital hemangiomas is discussed.

    'Panta rhei': everything flows. The significance of bronchial asthma is currently changing to no less a degree than medicine itself. In order to know where we are, we must know where we have come from. The historical course of bronchial asthma to some extent reflects the history of medicine itself: the Hellenic systems were followed by Byzantine, Galenic teaching methods, while Humanism and the Renaissance were followed by the considerable fireworks of early modern medicine. This continued with Magendie's experimental revolution in the 19th century and, finally, analytic medical research up to today.

    In a 4-year period, 196 lungs from patients with and without chronic obstructive pulmonary disease were examined postmortem for the presence of atrophy in segmental and subsegmental bronchi. As a result of simultaneous postmortem spirometry, cinefluorobronchography and partitioning of airways resistance, plus later assessment of anatomic emphysema, bronchial atrophy emerges as only one of at least three factors usually cooperating in production of abnormal expiratory airway collapse. In selected cases, bronchial atrophy appears to be an important contributor to expiratory airways obstruction. ImagesFig 1 PMID:5021107

    Identification of the 47,XXX karyotype often occurs adventitiously during prenatal fetal karyotyping in cases of advanced maternal age. Although most females with 47,XXX appear healthy at birth, various types of congenital malformations have been reported, of which urinary tract anomalies are the most frequent. We report on 2 newborns with 47,XXX and congenital cardiac defects, one of whom had duodenal atresia and the other an occipital encephalocele. This expands the spectrum of malformations reported in association with the triple-X syndrome. We also present a review of the literature on non-urinary tract malformations in females with 47,XXX. We conclude that prenatal identification of the 47,XXX karyotype is an indication for detailed fetal ultrasonography which should include examination of multiple organ systems. Such prenatal screening for possible associated congenital malformations should help to ensure optimal perinatal clinical management of 47,XXX cases.

  17. Biliary Atresia: 50 Years after the First Kasai

    PubMed Central

    Wildhaber, Barbara E.

    2012-01-01

    Biliary atresia is a rare neonatal disease of unknown etiology, where obstruction of the biliary tree causes severe cholestasis, leading to biliary cirrhosis and death in the first years of life, if the condition is left untreated. Biliary atresia is the most frequent surgical cause of cholestatic jaundice in neonates and should be evoked whenever this clinical sign is associated with pale stools and hepatomegaly. The treatment of biliary atresia is surgical and currently recommended as a sequence of, eventually, two interventions. During the first months of life a hepatoportoenterostomy (a “Kasai,” modifications of which are discussed in this paper) should be performed, in order to restore the biliary flow to the intestine and lessen further damage to the liver. If this fails and/or the disease progresses towards biliary cirrhosis and life-threatening complications, then liver transplantation is indicated, for which biliary atresia represents the most frequent pediatric indication. Of importance, the earlier the Kasai is performed, the later a liver transplantation is usually needed. This warrants a great degree of awareness of biliary atresia, and the implementation of systematic screening for this life-threatening pathology. PMID:23304557

    Congenital heart defects (CHD) affect approximately 7% of infants, and account for 3% of all infant deaths. CHD is most often caused by the defects associated with ductus arteriosus, which is a vessel that usually closes shortly after birth. The types of CHD include tetralogy of fallot, hypoplastic left heart syndrome, pulmonary atresia, total anomalous pulmonary venous return, transposition of great arteries, tricuspid atresia and truncus arteriosus. There are some risk factors that can increase the chance of a fetus developing CHD such as prematurity, an existing CHD in a first-degree relative, genetic syndromes, infections in utero, maternal drug consumptions and disorders. CHD is diagnosed is through different techniques including pulse oximetry, echocardiograms and physical exams. In this review, we examined the current incidence of CHD, the risk factors associated with CHD, the current methods of diagnosis and surgical options used to repair the defects. PMID:27168772

    In a 7-day-old infant referred because of bile-stained vomiting, jaundice and lack of meconium, radiological examination revealed the 'double-bubble' sign of duodenal atresia as well as dextrocardia. This infant also had a strawberry haemangioma on the right shoulder. Operation disclosed situs inversus and a preduodenal portal vein as well as duodenal atresia. A side-to-side duodeno-jejunostomy was performed successfully without damage to the anomalous vein. The history of polyhydramnion during gestation, the presence of other anomalies, the rapid onset of bile-stained vomiting and the classic 'double-bubble' sign, together appeared to indicate that the duodenal atresia was intrinsic and not due to the external pressure of the anomalous vein on the duodenum.

    Congenital thrombophilia is a thrombotic diathesis caused by a variety of genetic abnormalities in blood coagulation factors or their inhibitory factors associated with physiological thrombus formation. Patients with congenital thrombophilia often present with unusual clinical episodes of venous thrombosis (occasionally combined with pulmonary embolism, known as venous thromboembolism) at a young age and recurrence in atypical vessels, such as the mesenteric vein and superior sagittal sinus, often with a family history of this condition. Studies in Japan as well as in western countries have shown congenital thrombophilia to be caused by a wide variety of genetic abnormalities in natural anticoagulant proteins, such as antithrombin, protein C, and protein S. However, there may still be many unknown causes of hereditary thrombosis. We recently reported a case of hereditary thrombosis induced by a novel mechanism of antithrombin resistance, that is, congenital thrombophilia caused by a gain-of-function mutation in the gene encoding the coagulation factor prothrombin.

    PubMed

    Rothenberg, S S

    2013-01-01

    The first thoracoscopic esophageal atresia with tracheoesophageal fistula (EATEF) repair was performed in March of 2000. This report evaluates the results and evolution of the technique in a single surgeons' experience after the first decade of thoracoscopic EATEF repair. From March 2000 to September 2012, 52 consecutive patients with type 3 EATEF, and an additional nine patients with pure esophageal atresia (EA) were repaired by or under the direct supervision of a single surgeon. Patient weight ranged from 1.2 to 3.8 kg (mean 2.6 kg). Twenty-two patients had significant associated congenital anomalies. The repairs were performed using three ports. The fistula was ligated using a single endoscopic clip, and the anastomosis was performed using a single layer of interrupted sutures. A transanastomotic tube and chest drain were left in all cases. Fifty-one of the 52 procedures were completed successfully thoracoscopically. Operative times ranged from 50 to 120 minutes (average 85 minutes). There were three clinical leaks, one in an EATEF and two in patients with long-gap pure EA, all resolved with conservative therapy. Oral feedings were started on day 5 in all other patients. Twelve of 61 patients required dilations (1-9), and 18 required a Nissen fundoplication for severe reflux. One patient required a thoracoscopic aortopexy for severe tracheomalacia. All patients are currently on full oral feedings. No patient has any evidence of chest wall asymmetry, winged scapula, or clinically significant scoliosis. There have been no recurrent fistulas. Thoracoscopic EA repair has proven to be an effective and safe technique. Initial experience resulted in a higher stricture rate, but this improved with experience and changes in technique. The results are superior to that of documented open series and avoid the morbidity of an open thoracotomy.

    2016-12-01

    Management of patients with Eisenmenger syndrome with pulmonary atresia is challenging because of the complexity of the structure-function relationship of the components of the syndrome. Multi-modality imaging including cardiac magnetic resonance (CMR) 4D Flow offers unprecedented opportunities to unravel, at least in part, some of these components, and thus help in the management of these patients. In this study, we describe the use of these integrated methods with particular reference to CMR 4D Flow in a patient with Eisenmenger syndrome and pulmonary atresia and outline both the utility and the limitations. A comprehensive cardiac magnetic resonance (CMR) 4D Flow analysis was performed preoperatively and postoperatively, during peak systole, late systole, early diastole, and late diastole. The focus of the present study was to investigate the pattern of flow and dynamic changes at different levels of the aorta, as well as in the duct and the pulmonary arteries. Preoperatively, a right-handed helix and a vortex were observed in the dilated ascending aorta, and the duct flow was mainly dependent on reverse, upstream flow from the descending aorta, distal to the duct, during diastole, denoting low pulmonary vascular capacitance. Following repair, the flow in the ascending aorta and the descending aorta changed markedly. These changes included both timing and intensity of the right-handed helix, as well as the vortex in the ascending aorta. The significance of the observed changes in flow pattern and their influence on wall structure and function are discussed. Our study demonstrates the extremely powerful potential of CMR 4D Flow in the management of complex congenital anomalies.

    Introduction Although it has been more than 250 years since the first description of choanal atresia (CA), there are still doubts about this abnormality. The differences between unilateral and bilateral forms are seldom discussed. Objectives Aggregate data from patients diagnosed with CA, grouping patients with unilateral and bilateral forms. Methods Retrospective study. Results Eighteen patients were included: 12 (66.6%) presented bilateral atresia, of which 77.8% were mixed bony-membranous type and 22.2% were pure bony type. From the 12 patients with bilateral atresia, 10 presented related malformations, 3 of whom had CHARGE syndrome (coloboma, heart defects, choanal atresia, retardation of growth and development, genitourinary problems, ear abnormalities). From the remaining 6 patients with unilateral atresia, only 2 showed malformations, 1 renal and 1 cardiac. All patients with unilateral atresia needed only 1 surgical procedure, and patients with the bilateral form needed a median of 2.85 interventions (p = 0.003). The median age of surgical procedure in the unilateral group was 6 years, ranging from 6 months to 18 years, and in the bilateral group was 25 days, ranging from 6 days to 6 years (p = 0.003). The median interval between diagnosis and surgery was 9 months in the unilateral group, ranging from 1 month to 18 years, and in the bilateral group was 1 day, ranging from 1 day to 2 months (p = 0.001). Discussion and Conclusions Success rates with the endoscopic approach vary from 62 to 100%. Nonetheless, most of these reports present results without considering the number of compromised sides. In our opinion, unilateral and bilateral cases involve distinct patients (taking into account the related malformations), have diverging clinical presentations, and show discrepant restenosis rates and therefore could be considered in different groups of analysis.

    Congenital diarrhoea of heterogenic etiology is a rare cause of chronic diarrhoea. Characteristic features are: onset in the first weeks of life, life-threatening severe dehydratation and electrolyte disorders leading to a necessity of long-term parenteral nutrition. The clinical onset may be delayed and the degree of diarrhoea may be modest, making the diagnosis difficult. The main causes of congenital diarrhoea such as intestine electrolytes, carbohydrates, lipid and protein transport disorders and congenital enzymatic deficiencies, enterocyte polarization disorders, hormonal, immunological, metabolic, genetic and congenital anatomic disorders are presented in the paper. Some of them, such as: microvillus inclusion disease, tufting enteropathy, intestinal anedocrynosis, IPEX syndrome (immunodysregulation polyendocrinopathy enteropathy X-linked syndrome) have been described recently. One of the basic investigations, when congenital diarrhea is suspected, is general examination of the stool, its electrolyte concentration and serum electrolytes and blood gas analysis. Often, small bowel biopsy with histological examination (with the use of electronic microscopy and PAS staining) is indicated. In some cases molecular examination is possible and indicated. In differential diagnosis other, more frequent causes of chronic diarrhea of infancy, have to be excluded. In most of the cases of congenital diarrhoea there is no casual treatment available - usually long-term parenteral nutrition is necessary.

    Although the outcome of newborns with surgical congenital diseases (e.g., diaphragmatic hernia; esophageal atresia; omphalocele; gastroschisis) has improved rapidly with recent advances in perinatal intensive care and surgery, infant survivors often require intensive treatment after birth, have prolonged hospitalizations, and, after discharge, may have long-term sequelae including gastro-intestinal comorbidities, above all, gastroesophageal reflux (GER). This condition involves the involuntary retrograde passage of gastric contents into the esophagus, with or without regurgitation or vomiting. It is a well-recognized condition, typical of infants, with an incidence of 85%, which usually resolves after physiological maturation of the lower esophageal sphincter and lengthening of the intra-abdominal esophagus, in the first few months after birth. Although the exact cause of abnormal esophageal function in congenital defects is not clearly understood, it has been hypothesized that common (increased intra-abdominal pressure after closure of the abdominal defect) and/or specific (e.g., motility disturbance of the upper gastrointestinal tract, damage of esophageal peristaltic pump) pathological mechanisms may play a role in the etiology of GER in patients with birth defects. Improvement of knowledge could positively impact the long-term prognosis of patients with surgical congenital diseases. The present manuscript provides a literature review focused on pathological and clinical characteristics of GER in patients who have undergone surgical treatment for congenital abdominal malformations.

    2013-01-01

    Biliary atresia is a rare idiopathic neonatal cholestatic disease characterized by the destruction of both the intra- and extrahepatic biliary ducts. As the disease is progressive all cases will develop portal fibrosis, cirrhosis, and portal hypertension with the sequelae of varices, jaundice, and eventually liver failure requiring a transplant. Survival rates have improved considerably with many females living well in to be childbearing age. Due to the complexity of the disease these pregnancies are considered, high risk. We report the antenatal, intrapartum, and postpartum managements of a pregnancy complicated by biliary atresia. Furthermore, we highlight the importance of a multidisciplinary team approach in optimizing obstetric care for this high risk group. PMID:24459595

    Pyloric atresia (PA) is uncommon. It occurs in 1:100000 live births. Neonates usually present soon after birth with copious non-bilious vomiting. The treatment is surgical and its prognosis is poor, especially, when it is associated with epidermolysis bullosa (EB). The aim of this study was to evaluate the clinical presentation, diagnosis, operative management, post-operative courses, and outcome in infant with PA, based in our cases and literature review. Charts of 10 patients who underwent surgery for PA in the department of paediatric surgery in a Teaching Hospital in Tunisia (Monastir) between 1990 and 2012 were reviewed. Data were analysed for demographic, clinical, therapeutic, and prognostic characteristics. The average of age at presentation was 2 days and there were six males and four females. The main presenting symptoms were non-bilious vomiting in 90% of cases. Abdominal X-ray showed gastric dilatation with an absence of gas in the rest of the intestinal tract in 90%, and a pneumoperitoneum in one. The surgical approach was laparotomy in all cases. Gastric perforation was observed in one patient and was completely repaired. The distribution of the anatomic variations was type A in nine cases and type B in one. Five patients underwent excision of the diaphragm and Heineke-Mikulicz pyloroplasty and gastroduodenostomy in the other five cases. Identified associated anomalies were Down's syndrome in one and EB in 2 (20%), one family has three affected sibling. Post-operative mortality rate was 70%. No standard surgical approach can be adopted a better management of PA or the associated anomalies depends on an early diagnosis and the availability of neonatal intensive care unit.

    Coke-oven workers are exposed to dust and irritant gases. Therefore they are at risk of developing lung diseases including chronic bronchitis. Nonspecific bronchial hyperresponsiveness (BHR) has been advocated as a potential risk factor predisposing to the development of chronic bronchitis. In a previous study, we showed that prevalence of BHR was higher in retired coke-oven workers than in retired blast furnace workers. The present study was carried out to determine the prevalence of BHR in active steelworkers. Thus, 137 coke-oven workers and 150 blast furnace workers underwent clinical examination, a standardized questionnaire for the study of respiratory symptoms, pulmonary function testing and methacholine aerosol challenge. The study demonstrates a higher prevalence and degree of BHR [provocative concentration of methacholine causing a 20% fall in forced expiratory volume in one second (PC20) < or = 8 mg x mL(-1)] in coke-oven workers than in blast furnace workers (31.4 versus 6.7%; p<0.001). Moreover, the frequency of respiratory symptoms and basal bronchial obstruction were greater among coke-oven workers with BHR in nonresponders. The basal maximum expiratory flow from 25-75% of forced vital capacity and the respiratory symptoms were correlated with bronchial responsiveness. The lack of correlation observed between BHR and the intensity of smoking or years spent in coke-oven environment may be explained by the high proportion of smokers, the worker turnover in the steel plant, and the "healthy worker effect". In conclusion, the higher prevalence and degree of bronchial hyperresponsiveness in coke-oven workers suggests that coke-oven pollutants are more intense irritants than those that escape from blast furnaces.

    Bronchial haemangioma is an exceptionally rare cause of haemoptysis in the adult. There are currently less than 10 recorded cases in the literature. Airway haemangiomas are generally seen in infants with coexistent cutaneous haemangiomas. The incidence of bronchial haemangioma in adults remains unknown. This case reports the diagnosis and treatment of a bronchial haemangioma in a 56 year-old male presenting with a one-month history of haemoptysis. Bronchial haemangioma diagnosis was confirmed and excision performed by bronchoscopy without complication. Bronchial haemangioma should be a considered differential diagnosis in the presence of meaningful haemoptysis when an endoluminal lesion is visualised on computed tomography scan. This case also demonstrates that bronchial haemangiomas can be successfully removed via bronchoscopy with minimal risk and discomfort to the patient.

    This prospective study was initiated to document the success rate obtained in the treatment of colonic atresia in calves, identify factors that influence survival rate, and to report the histopathological appearance of the proximal blind end of the ascending colon. Forty-three calves with intestinal obstruction due to colonic atresia were admitted to the Ontario Veterinary College between September 1982 and May 1986. Parameters recorded prospectively in this study included age, breed, sex, history, vital signs, acid-base and electrolyte status, location of intestinal atresia, medical and surgical management, and outcome. The typical history and clinical signs included failure to pass meconium or feces, decreased appetite, and progressive depression and abdominal distension. The most common site of colonic atresia was the midportion of the spiral loop of the ascending colon (n = 25). Of the 43 calves, three (7%) were euthanized at surgery, 21 (49%) died in the hospital, and 19 (44%) survived and were discharged from the hospital. Four of the surviving calves died subsequent to discharge giving an overall long-term (mean 15.9 months) survival rate of 35%. No significant risk factors were identified, although experienced surgeons showed a trend towards increased survival rate. ImagesFigure 2.Figure 3.Figure 4.Figure 5. PMID:17423141

    Malignant infantile osteopetrosis is a rare genetic disease characterized by increased bone density due to osteoclastic dysfunction. We report on the case of a 3-month-old girl who was referred to our hospital by the ENT department for severe anemia in the context of bilateral choanal atresia. Clinical examination showed failure to thrive, anemia, respiratory distress, bilateral choanal atresia, and chest deformation. The abdomen was soft with large hepatosplenomegaly. We noted a lack of eye tracking, no optical-visual reflexes, and left nerve facial paralysis. The blood count showed normocytic normochromic anemia with severe thrombocytopenia. The infectious work-up and blood smears were negative. The skeleton X-ray showed diffuse bone densification of the skull, long bones, pelvis, vertebrae, and ribs. The facial bone CT confirmed membranous choanal atresia. The molecular biology search for the TCIRG1 gene mutation was not available. The patient had supportive treatment (transfusion, oral steroid, vitamin D, oxygen, nutrition). Bone marrow transplantation was indicated but not available. She died at 6 months in a context of severe anemia and bleeding. Malignant infantile osteopetrosis is rare and symptoms are nonspecific. Diagnosis should be considered in young infants presenting refractory anemia, particularly in the context of choanal atresia. Bone marrow transplantation remains the only curative treatment.

    Eosinophilic esophagitis (EoE) has only rarely been reported in esophageal atresia (EA) patients. A retrospective case analysis of all EA patients born at our center between January 1999 and April 2012 was performed. A total of 113 of patients were identified; 10 patients were excluded as a result of inadequate data. Eighteen patients (17%) were diagnosed with EoE. The average number of eosinophilis was 30/high-power field (HPF) (19/HPF-80/HPF). The median age for diagnosis of EoE was 1 year and 6 months (8 months-8 years and 7 months). Children with EoE had a significantly greater incidence of reflux symptoms, dysphagia, tracheomalacia, and 'hypoxic spells' (P < 0.05). EoE patients also underwent significantly more surgery including fundoplication and aortopexy when compared with those without EoE (P < 0.0001). Although the incidence of gastrostomy was greater in the EoE group (33% vs. 13%), this was not statistically significant. Half of the EoE patients had a coexisting atopic condition at time of diagnosis. The commonest condition was asthma 7/18 (38%) followed by specific food allergy 6/18 (33%). EoE was treated in 11 patients with either swallowed fluticasone or budesonide slurry. All improved clinically. Histologically, five had complete resolution and six had partial improvement. Six children with EoE were treated with acid suppression alone. All improved clinically, and 5/6 had subsequent histological resolution. One child who received acid suppression and an exclusion diet also improved. Seven patients (38%) had an esophageal stricture at time of EoE diagnosis. Five were dilated at time of the initial endoscopy, prior to the diagnosis of EoE being available. Two patients had resolution of their strictures on medical treatment of their EoE alone and did not require further dilatation. EoE was seen in 17% of children with EA in this study. EoE should be considered in EA patients with persistent symptoms on standard reflux treatment, increasing

    Congenital torticollis is a very common postural deformity, characterized by a more or less severe retraction of sternocleidomastoid muscle. Any treatment, else that "good sense" counsels given to the parents, is indicated. The evolution is spontaneously favorable in the majority of cases before the age of one year old. The elimination of differential diagnosis (vertebral and/or neurological malformations, ocular, tumor) is the key-point. Screening of congenital hip dislocation is mandatory because the physiopathology is the same in both diseases. A remaining torticolis after 18 months of age may be an indication to sternocleidomastoid muscle lengthening.

    Objectives To quantify health related quality of life (HRQOL) of patients with biliary atresia with their native livers and compare them with healthy children and patients with biliary atresia post-liver transplant (LT) and to examine the relationship between HRQOL and medical variables. Study design A cross-sectional HRQOL study of patients with biliary atresia with their native livers (ages 2-25 years) was conducted and compared with healthy and post-LT biliary atresia samples using PedsQL™ 4.0 child self and parent proxy reports, a validated measure of physical/psychosocial functioning. Results 221 patients with biliary atresia with native livers (54% female, 67% white) were studied. patient self and parent proxy reports showed significantly poorer HRQOL than healthy children across all domains (p < 0.001), particularly in emotional and psychosocial functioning. Child self and parent proxy HRQOL scores from patients with biliary atresia with their native livers and post-LT biliary atresia were similar across all domains (p=NS). Child self and parent proxy reports showed moderate agreement across all scales, except social functioning (poor to fair agreement). On multivariate regression analysis, black race and elevated total bilirubin were associated with lower Total and Psychosocial HRQOL summary scores. Conclusions HRQOL in patients with biliary atresia with their native livers is significantly poorer than healthy and similar to post-LT biliary atresia children. These findings identify significant opportunities to optimize the overall health of patients with biliary atresia. PMID:23746866

    Intestinal atresia was found in 29 animals and stenosis in five. Atresia was found in the duodenum in one pup; in the jejunum in nine calves, two lambs and one piglet; in the ileum in one pup, one lamb and one piglet; and in the colon in one foal, seven calves, one lamb, one piglet and three kittens. Stenosis was found in the duodenum of a foal, in the jejunum in two calves and one pup, and in both the ileum and the colon of a kitten. One lamb showed ileal atresia as well as ileal stenosis. We classified the atresia as type 1, membrane atresia (four cases); type 2, cord atresia (six cases); and type 3, blind-end atresia (19 cases). In the literature and our own study, atresia was found only in the small intestine in puppies, but in foals and kittens it was found only in the colon. Atresia of the colon is more common in animals than in man, but multiple atresia, frequent in man, is rare in animals.

    In contrast to the sophisticated music processing reported in the general population, individuals with congenital amusia show deficits in music perception and production. Congenital amusia occurs without brain damage, sensory or cognitive deficits, and has been suggested as a lifelong deficit with genetic origin. Even though recognized for a long time, this disorder has been systematically studied only relatively recently for its behavioral and neural correlates. The currently most investigated hypothesis about the underlying deficits concerns the pitch dimension, notably with impaired pitch discrimination and memory. Anatomic and functional investigations of pitch processing revealed that the amusic brain presents abnormalities in the auditory and inferior frontal cortices, associated with decreased connectivity between these structures. The deficit also impairs processing of pitch in speech material and processing of the time dimension in music for some of the amusic individuals, but does not seem to affect spatial processing. Some studies suggest at least partial dissociation in the disorder between perception and production. Recent studies revealed spared implicit pitch perception in congenital amusia, supporting the power of implicit cognition in the music domain. Current challenges consist in defining different subtypes of congenital amusia as well as developing rehabilitation programs for this "musical handicap."

    One-lung ventilation is commonly used to facilitate visualization of the field during thoracic surgery. New devices for performing this technique that have become available over the past 2 decades include the Univent bronchial blocker incorporated in a single-lumen tube, the Arndt endobronchial blocker, and the Cohen endobronchial blocker. Although insertion of a double-lumen tube is still the method used most often to isolate the lung, bronchial blockade is an increasingly common technique and, in certain clinical settings, provides advantages over the double-lumen tube. This review provides an update on new concepts in the use of bronchial blockers as a technique for lung isolation and one-lung ventilation. The literature search was performed on MEDLINE through PubMed using the keywords bronchial blockers and thoracic surgery. The search span started with 1982-the year the first modern bronchial blocker was described - and ended with February 2006.

    Isolated unilateral pulmonary artery agenesis is a rare congenital anomaly that may be complicated with hemoptysis, recurrent pulmonary infections or pulmonary hypertension. To our knowledge the occurrence of a coronary syndrome associated with a coronary-to-bronchial artery saccular aneurysmal collateralization has never been described before. A 44-year-old female presented a congenital right pulmonary artery agenesis associated with a hypotrophic and multicystic right lung complicated with recurrent bronchitis. This patient had a coronary syndrome for which the coronary artery imaging showed a coronary-to-bronchial artery collateralization with an aneurysm at this level. It gives rise to a coronary syndrome by coronary steal. Two bronchial collaterals arising from a diaphragmatic artery and the subclavian artery were also found on the computed tomography (CT)-scan. This last collateral also showed another saccular aneurysm. We first performed an embolization of those two aneurysms in order to decrease the risk of hemorrhage and coronary steal, before performing a right pneumonectomy. In this case, the surgery was indicated because of the pathological lung and the risk of postembolization ischaemia. The postoperative course was uneventful and the patient was doing well six months later.

    We previously reported bronchial circulation contributes to pulmonary edema and increases shunt fraction following smoke inhalation, and bronchial blood flow significantly increases in inhalation injury. We hypothesized reduction of bronchial blood flow reduces exudation to the airway and ameliorates lung injury from combined burn and smoke insults (B & S injury). Method Merino ewes (n=28) randomly divided into three groups (1: bronchial artery ligated and injured (Injury + ligation group); 2: bronchial artery left intact and injured (Injury + no ligation group); 3: bronchial artery ligated but not injured (No injury + ligation group) were subjected to a flame burn and inhalation injury under halothane anesthesia. Parameters were analyzed using Scheffe’s post hoc test (P<0.05). All Groups were resuscitated with Ringer lactate solution and placed on a ventilator for 48 hours. Results Pulmonary gas exchange (PaO2/FiO2) improved in injury + ligation group. Further, obstruction score, an index of airway cast formation, significantly changed between injury + no ligation group compared to both ligation groups. Conclusion Bronchial circulation plays a significant role in lung injury after B & S injury, and reduction of bronchial blood flow by bronchial artery ligation reduces bronchial exudation, resulting in improved gas exchange.

    The management of congenital scoliosis requires a systematic approach with careful attention to detail. Any fortuitous diagnosis of vertebral anomalies in infancy, even if there is no significant scoliosis at that time on x-ray, requires frequent clinical and radiographic follow-up to detect progression. The presence of associated anomalies of the spinal cord, the kidneys and the heart should be evaluated by MRI, renal ultrasound or IVP, with cardiology evaluation as indicated. Curve progression or severe vertebral anomalies known to cause curve progression require immediate treatment to prevent deformity. Significant thoracic deformity, especially in a patient with thoracic insufficiency syndrome, is best treated with expansion thoracoplasty. The patient with congenital scoliosis requires a long term commitment to care with frequent orthopaedic follow-up throughout the growing years along with routine pulmonary function assessment once the patient is able to cooperate with testing.

Medical therapy involves decreasing the production of CSF. The most common surgical treatment is placement of a ventriculoperitoneal shunt. Postoperative complications may include infection, blockage, drainage abnormalities, and mechanical failure.

    Aim: To review nine-year experience in managing jejuno-ileal atresia (JIA) by primary resection and anastomosis and identify factors associated with reoperations. Methods: From April 2006 to May 2015, all consecutive neonates who underwent bowel resection and primary anastomosis for JIA were analyzed retrospectively. Patients with temporary enterostomy were excluded. Patient demographics, types of atresia, surgical techniques, need for reoperations, and long-term outcomes were investigated. Results: A total of forty-three neonates were included, in which nineteen (44.2%) of them were preterm and fourteen (32.6%) were of low birth weight. Thirteen patients (30.2%) had jejunal atresia whereas thirty patients (69.8%) had ileal atresia. Volvulus, intussusception and meconium peritonitis were noted in 12, 8, and13 patients, respectively. Eight patients (18.6%) had short bowel syndrome after operation. Ten patients (23.3%) required reoperations from 18 days to 4 months after the initial surgery due to anastomotic stricture (n=1), adhesive intestinal obstruction (n=1), small bowel perforation (n=2) and functional obstruction (n=6). Prematurity and low birth weight were associated with functional obstruction leading to reoperation (p=0.04 and 0.01 respectively). The overall long-term survival was 97.7%. All surviving patients achieved enteral autonomy and catch-up growth at a median follow-up of 4.7 years. Conclusion: Long-term survival of JIA after primary resection and anastomosis are excellent. However, patients have substantial risk of early reoperations to tackle intraabdominal complications. PMID:27896150

    2015-08-01

    Dysphagia or swallowing disorder is very common (range, 15-52%) in patients with esophageal atresia. Children present with a wide range of symptoms. The most common diagnostic tools to evaluate esophageal dysphagia, such as upper barium study and manometry, aim to characterize anatomy and function of the esophageal body and the esophagogastric junction (EGJ). Using these technologies, a variety of pathological motor patterns have been identified in children with esophageal atresia. However, the most challenging part of diagnosing patients with esophageal dysphagia lies in the fact that these methods fail to link functional symptoms such as dysphagia with the esophageal motor disorders observed. A recent method, called pressure-flow analysis (PFA), uses simultaneously acquired impedance and manometry measurements, and applies an integrated analysis of these recordings to derive quantitative pressure-flow metrics. These pressure-flow metrics allow detection of the interplay between bolus flow, motor patterns, and symptomatology by combining data on bolus transit and bolus flow resistance. Based on a dichotomous categorization, flow resistance at the EGJ and ineffective esophageal bolus transit can be determined. This method has the potential to guide therapeutic decisions for esophageal dysmotility in pediatric patients with esophageal atresia.

CTA depicted a hypertrophied bronchial artery to the right upper lobe and showed signs of recent bleeding at that location. Bronchial artery embolization (BAE) was performed with gelfoam slurry, because pronounced shunting to the pulmonary artery was present. Immediately after BAE, the patient developed bilateral cortical blindness. Control angiography showed an initially not opacified anastomosis between the embolized bronchial artery and the right subclavian artery, near to the origin of the right vertebral artery. Cessation of outflow in the bronchial circulation reversed the flow through the anastomosis and allowed for spill of embolization material into the posterior circulation. Unfortunately the cortical blindness presented was permanent.

    The bronchial tree is of direct clinical importance in the context of respective diseases, such as chronic obstructive pulmonary disease (COPD). It furthermore constitutes a reference structure for object localization in the lungs and it finally provides access to lung tissue in, e.g., bronchoscope based procedures for diagnosis and therapy. This paper presents a comprehensive anatomical model for the bronchial tree, including statistics of position, relative and absolute orientation, length, and radius of 34 bronchial segments, going beyond previously published results. The model has been built from 16 manually annotated CT scans, covering several branching variants. The model is represented as a centerline/tree structure but can also be converted in a surface representation. Possible model applications are either to anatomically label extracted bronchial trees or to improve the tree extraction itself by identifying missing segments or sub-trees, e.g., if located beyond a bronchial stenosis. Bronchial tree labeling is achieved using a naïve Bayesian classifier based on the segment properties contained in the model in combination with tree matching. The tree matching step makes use of branching variations covered by the model. An evaluation of the model has been performed in a leaveone- out manner. In total, 87% of the branches resulting from preceding airway tree segmentation could be correctly labeled. The individualized model enables the detection of missing branches, allowing a targeted search, e.g., a local rerun of the tree-segmentation segmentation.

    Over the past decade, amniotic fluid-derived stem cells have emerged as a novel, experimental approach for the treatment of a wide variety of congenital anomalies diagnosed either in utero or postnatally. There are a number of unique properties of amniotic fluid stem cells that have allowed it to become a major research focus. These include the relative ease of accessing amniotic fluid cells in a minimally invasive fashion by amniocentesis as well as the relatively rich population of progenitor cells obtained from a small aliquot of fluid. Mesenchymal stem cells, c-kit positive stem cells, as well as induced pluripotent stem cells have all been derived from human amniotic fluid in recent years. This article gives a pediatric surgeon’s perspective on amniotic fluid stem cell therapy for the management of congenital anomalies. The current status in the use of amniotic fluid-derived stem cells, particularly as they relate as substrates in tissue engineering-based applications, is described in various animal models. A roadmap for further study and eventual clinical application is also proposed. PMID:22986340

    Toxoplasmosis is caused by infection with the parasite Toxoplasma gondii. It is one of the most common parasitic infections in humans and is most typically asymptomatic. However, primary infection in a pregnant woman can cause severe and disabling disease in the developing fetus. Recent developments have included increased understanding of the role of parasite genotype in determining infectivity and disease severity. Risk factors for acquisition of infection have been better defined, and the important role of foodborne transmission has been further delineated. In addition, strategies have emerged to decrease mother-to-child transmission through prompt identification of acutely infected pregnant women followed by appropriate treatment. Refined diagnostic tools, particularly the addition of immunoglobulin G avidity testing, allow for more accurate timing of maternal infection and hence better decision making during pregnancy. Congenitally infected children can be treated, beginning in utero and continuing through the first year of life, to ameliorate the severity of disease. However, despite these many advances in our understanding of congenital toxoplasmosis prevention and treatment, significant areas of study remain: we need better drugs, well defined strategies for screening of pregnant women, improved food safety, and improved diagnostic tests.

    The Klippel-Feil syndrome is a congenital anomaly characterized by fusion of the cervical vertebrae. It is often associated with serious congenital anomalies of the nervous, cardiovascular and urogenital systems. One of the anomalies which have not been thoroughly investigated to date are that accompanying Klippel-Feil syndrome and enlarged Eustachian tube. We report a case of type III Klippel-Feil syndrome with associated rib anomalies such as hypoplastic and bifid ribs, scoliosis and elevated scapula (Sprengel's disease). The patient also presented hemifacial microsomia and central facial palsy of the lower right side of the face, urogenital and cardiovascular anomaly, congenital anorectal atresia and right-sided congenital aural atresia with microtia. Computer tomography of temporal bone showed abnormal extension of the right Eustachian tube with anomalies of the middle and inner ear on this particular side. In this case report we discuss the associated anomalies of the patient with Klippel-Feil syndrome. The aim of this case report is to draw attention to very rare case of patient with Klippel-Feil syndrome and enlarged pharyngotympanic tube.

    Although duodenal atresia (DA) is present in only 4-7% of all Down Syndrome (DS) individuals, 30-50% of all congenital duodenal atresias occur in the DS population, suggesting the presence of gene(s) on chromosome 21 that play an important role in intestinal development. We recently proposed a chromosome 21 gene dosage model to explain the phenotypic variance seen among DS individuals and presented a strategy to map genes involved in these phenotypic traits. We suggest that {open_quote}hyper-dosage{close_quote} resulting from normal allelic differences explains the phenotypic variation. A proportion of trisomic genotypes would exceed some activity threshold and express the trait. In affected individuals, this increase in expression is due to the presence of two identical copies of {open_quote}susceptibility{close_quote} allele, inherited from a heterozygous parent of origin. Individuals with trisomy 21 and a specific phenotypic defect should exhibit increased levels of disomic homozygosity in the region containing the gene involved in the defect`s etiology. These data can be used to map these genes. Using this approach, we have examined markers along the long arm of chromosome 21 among DS individuals with DA and determined the degree of disomic homozygosity at each marker. This frequency was compared to the level of disomic homozygosity among our entire DS study population consisting of approximately 380 DS families to test for linkage between DA and each marker. Preliminary analysis of 13 DS cases with DA indicates an increase in disomic homozygosity along the distal region of the chromosome, from HMG14 to D21S171, the most telomeric marker analyzed. An additional 15 cases are currently being analyzed to confirm and better define this candidate region.

  10. Oto-facial syndrome and esophageal atresia, intellectual disability and zygomatic anomalies - expanding the phenotypes associated with EFTUD2 mutations

    2013-01-01

    Background Mutations in EFTUD2 were proven to cause a very distinct mandibulofacial dysostosis type Guion-Almeida (MFDGA, OMIM #610536). Recently, gross deletions and mutations in EFTUD2 were determined to cause syndromic esophageal atresia (EA), as well. We set forth to find further conditions caused by mutations in the EFTUD2 gene (OMIM *603892). Methods and results We performed exome sequencing in two familial cases with clinical features overlapping with MFDGA and EA, but which were previously assumed to represent distinct entities, a syndrome with esophageal atresia, hypoplasia of zygomatic complex, microcephaly, cup-shaped ears, congenital heart defect, and intellectual disability in a mother and her two children [AJMG 143A(11):1135-1142, 2007] and a supposedly autosomal recessive oto-facial syndrome with midline malformations in two sisters [AJMG 132(4):398-401, 2005]. While the analysis of our exome data was in progress, a recent publication made EFTUD2 mutations highly likely in these families. This hypothesis could be confirmed with exome as well as with Sanger sequencing. Also, in three further sporadic patients, clinically overlapping to these two families, de novo mutations within EFTUD2 were identified by Sanger sequencing. Our clinical and molecular workup of the patients discloses a broad phenotypic spectrum, and describes for the first time an instance of germline mosaicism for an EFTUD2 mutation. Conclusions The clinical features of the eight patients described here further broaden the phenotypic spectrum caused by EFTUD2 mutations or deletions. We here show, that it not only includes mandibulofacial dysostosis type Guion-Almeida, which should be reclassified as an acrofacial dysostosis because of thumb anomalies (present in 12/35 or 34% of patients) and syndromic esophageal atresia [JMG 49(12). 737-746, 2012], but also the two new syndromes, namely oto-facial syndrome with midline malformations published by Mégarbané et al.

    2014-01-01

    Inhomogeneous inflation or deflation of the lungs can cause dynamic pressure differences between regions and lead to interregional airflows known as pendelluft. This work first uses analytical tools to clarify the theoretical limits of pendelluft at a single bifurcation. It then explores the global and regional pendelluft that may occur throughout the bronchial tree in a realistic example using an in silico model of bronchoconstriction. The theoretical limits of pendelluft volume exchanged at a local bifurcation driven by sinusoidal breathing range from 15.5% to 41.4% depending on the relative stiffness of the subtended regions. When nonsinusoidal flows are considered, pendelluft can be as high as 200% inlet tidal volume (Vin). At frequencies greater than 10 Hz, the inertia of the air in the airways becomes important, and the maximal local pendelluft is theoretically unbounded, even with sinusoidal breathing. In a single illustrative numerical simulation of bronchoconstriction with homogenous compliances, the overall magnitude of global pendelluft volume was <2% of the tidal volume. Despite the small overall magnitude, pendelluft volume exchange was concentrated in poorly ventilated regions of the lung, including local pendelluft at bifurcations of up to 13% Vin. This example suggests that pendelluft may be an important phenomena contributing to regional gas exchange, irreversible mixing, and aerosol deposition patterns inside poorly ventilated regions of the lung. The analytical results support the concept that pendelluft may be more prominent in diseases with significant heterogeneity in both resistance and compliance. PMID:25170072

    The geometry and dimensions of branched structures such as blood vessels or airways are important factors in determining the efficiency of physiological processes. It has been shown that fractal trees can be space filling and can ensure minimal dissipation. The bronchial tree of most mammalian lungs is a good example of an efficient distribution system with an approximate fractal structure. Here we present a study of the compatibility between physical optimization and physiological robustness in the design of the human bronchial tree. We show that this physical optimization is critical in the sense that small variations in the geometry can induce very large variations in the net air flux. Maximum physical efficiency therefore cannot be a sufficient criterion for the physiological design of bronchial trees. Rather, the design of bronchial trees must be provided with a safety factor and the capacity for regulating airway calibre. Paradoxically, our results suggest that bronchial malfunction related to asthma is a necessary consequence of the optimized efficiency of the tree structure.

    1998-01-01

    Pulmonary atresia with intact ventricular septum (PAIVS) is a rare congenital cardiac anomaly that has been classified into two types: one is a more frequent type having dysplasia of tricuspid valve (TV) with a small annulus, underdeveloped right ventricle (RV) with a hypoplastic cavity and a hypertrophic wall; the other type has severe dysplasia of TV and dilatation of RV, right atrium (RA), and right atrioventricular junction with thinning of the RV wall. We performed a morphologic study on 11 autopsied hearts with PAIVS, giving particular emphasis to the variation of morphology of the TV. We could classify these hearts into 3 groups according to the degree of right ventricular development. In the first group of 7 cases (type I), the RVs were underdeveloped. Thick leaflets, restricted valve apparatus with short chordae, and small annuli were characteristics of the TV. In the second group of 3 cases (type II), the RVs showed marked enlargement of the cavity and thinning of the wall. The TV showed redundant, dysplastic, sail-like anterior leaflets, and the downward displacement of septal leaflet and/or posterior leaflet, which are the findings frequently observed in Ebstein's malformation. The RVs were dilated and with partially unguarded tricuspid orifice. The septal leaflet of the TV was dysplastic and, in two cases, the septal leaflet showed chordal structure at the upper surface facing the RA, which is a peculiar finding that has not been described in the literature. The remaining case was a heart with a moderately developed RV (type III). The TV showed mildly dysplastic appearance and we classify this as a separate type, because we could expect the best surgical results in this type. This type had optimal size of RV and the mildest degree of dysplasia of TV. In PAIVS, the morphology of TV correlates well with the type of the right ventricular development.

    Bronchial asthma can be diagnosed when a patient develops the clinical manifestations of bronchial reactivity: wheezing, cough, tachypnea, and dyspnea. Occasionally, despite immunotherapy, bronchodilator therapy, and avoidance of the provocative factors, some asthmatic patients do not respond to treatment. Bronchial inhalation challenge, a method to test airway reactivity after inhalation of a nonspecific drug, can be used to plan and assess different modes of treatment, as well as screen for bronchial hyperreactivity in an occupational setting.

    Biliary atresia is a severe cholangiopathy of early infancy that destroys extrahepatic bile ducts and disrupts bile flow. With a poorly defined disease pathogenesis, treatment consists of the surgical removal of duct remnants followed by hepatoportoenterostomy. Although this approach can improve the short-term outcome, the liver disease progresses to end-stage cirrhosis in most children. Further improvement in outcome will require a greater understanding of the mechanisms of biliary injury and fibrosis. Here, we review progress in the field, which has been fuelled by collaborative studies in larger patient cohorts and the development of cell culture and animal model systems to directly test hypotheses. Advances include the identification of phenotypic subgroups and stages of disease based on clinical, pathological and molecular features. Stronger evidence exists for viruses, toxins and gene sequence variations in the aetiology of biliary atresia, triggering a proinflammatory response that injures the duct epithelium and produces a rapidly progressive cholangiopathy. The immune response also activates the expression of type 2 cytokines that promote epithelial cell proliferation and extracellular matrix production by nonparenchymal cells. These advances provide insight into phenotype variability and might be relevant to the design of personalized trials to block progression of liver disease. PMID:26008129

    Background: Oesophageal atresia is a neonatal emergency surgery whose prognosis has improved significantly in industrialised countries in recent decades. In sub-Saharan Africa, this malformation is still responsible for a high morbidity and mortality. The objective of this study was to analyse the diagnostic difficulties and its impact on the prognosis of this malformation in our work environment. Patients and Methods: We conducted a retrospective study over 4 years on 49 patients diagnosed with esophageal atresia in the 2 Paediatric Surgery Departments in Dakar. Results: The average age was 4 days (0-10 days), 50% of them had a severe pneumonopathy. The average time of surgical management was 27 h (6-96 h). In the series, we noted 10 preoperative deaths. The average age at surgery was 5.7 days with a range of 1-18 days. The surgery mortality rate is 28 patients (72%) including 4 late deaths. Conclusion: The causes of death were mainly sepsis, cardiac decompensation and anastomotic leaks. PMID:26612124

    Congenital diaphragmatic hernia is a congenital malformation of the diaphragm, resulting in the herniation of the abdominal organs into the thoracic cavity. The most common types of congenital diaphragmatic hernia are Bochdalek hernia (postero-lateral hernia), Morgagni hernia (anterior defect), and diaphragm eventration (abnormal displacement of part or all of an otherwise intact diaphragm into the chest cavity). Congenital diaphragmatic hernia is a life-threatening pathology in infants, and a major cause of death due to pulmonary hypoplasia and pulmonary hypertension. We present a fatal case of congenital diaphragmatic hernia in a newborn. At the autopsy, a central defect of the diaphragm was found, 8 × 5 cm in size, that led to a herniation of the small intestine, the right lobe of the liver, and the right adrenal gland into the thorax. An esophageal atresia was associated with the congenital diaphragmatic hernia. The lungs showed severe hypoplasia and atelectasia. Physicians should pay attention to a prenatal diagnosis of congenital diaphragmatic hernia in order to prevent newborn fatalities.

The frequency of congenital anomalies was estimated at 0.013% in the area of the RUW. In the veterinary practice a frequency of 0.51% was found. The most prevalent anomalies were seen in legs (39% in the veterinary practice and 21% in RUW) followed by congenital anomalies of the spine (9% in the veterinary practice and 17% in RUW). Arthrogryposes were most frequent among the anomalies of the legs with 65% (veterinary practice) and 39% (RUW), respectively, of all cases of registered leg anomalies in the respective area. Umbilical hernia and atresia of segments of the intestinum were seen in 8-30% of all registered cases. The frequency of congenital anomalies differed not significantly among paternal half sib groups. A questionnaire was proposed for the registration of congenital anomalies in progeny tests of AI bulls. A series of photographs showing the most prevalent congenital anomalies is supporting the registration form.

    The coupling of Ricinus communis lectins to Sephadex G 25 was used in order to study mucins and other glycoproteins from human bronchial secretion. The major part of human bronchial mucins and other glycoproteins such as immunoglobulins A, bronchotransferrin and alpha1-antichymotrypsin were isolated by this procedure. A parallel study of human bronchial mucosa was achieved with peroxidase labeled Ricinus communis lectins; this study characterized goblet cells and mucous cells which contain mucins, and serous cells which are involved in the synthesis or the secretion of the other glycoproteins.

    Nasal obstruction in neonates is a potentially fatal condition due to their exclusive nasal breathing. The main cause is inflammatory or infectious rhinitis. Congenital, neoplastic, traumatic or iatrogenic causes are less frequent. Choanal atresia is the most common congenital nasal anomaly. A less common etiology of congenital nasal obstruction is pyriform aperture stenosis. Suspicion might arise in any newborn with varying degrees of stridor and respiratory distress, associated with the difficulty of passing a probe through anterior nares. Diagnosis should be confirmed by a computed tomography of the craniofacial massif. The therapeutic approach will depend on the severity of symptoms. We describe our experience with 5 patients with this condition, treated surgically using a sub-labial approach, and followed by nasal stenting.

    Biliary atresia is a rare birth defect that affects 1 in 12,000 to 1 in 19,500 live births. We used data from the National Birth Defects Prevention Study, a multistate case-control study, to identify potential risk factors for isolated biliary atresia (no additional unrelated major birth defects diagnosed). Infants were identified from eight states from 1997 to 2002, with clinical information abstracted from medical records. Potential risk factors assessed include: demographic factors, seasonality, preterm birth, maternal smoking, maternal alcohol use, maternal illicit drug use, maternal health, maternal medication use, maternal vitamin use, and maternal nutrition. Infants of non-Hispanic black mothers were more likely to have biliary atresia than infants of non-Hispanic white mothers (adjusted odds ratio (aOR) = 2.29, 95% confidence interval (CI) 1.07-4.93) and infants conceived during the spring season were more likely to have biliary atresia than infants conceived in winter (aOR = 2.33, 95%CI 1.05-5.16). Low intakes of vitamin E, copper, phosphorus, and beta tocopherol were associated with the occurrence of isolated biliary atresia (borderline significance). Low iron intake had a borderline inverse association with biliary atresia. While this analysis provides support for previous reports of a possible association between seasonal variation and the occurrence of biliary atresia, more data are needed to evaluate whether the seasonal variation is related to infectious agents. The role of nutrients in the development of biliary atresia remains unclear. Further studies of genetic, infectious, and nutrient exposures and the association of biliary atresia are warranted.

    Ovarian folliculogenesis corresponds to the development of follicles leading to either ovulation or degeneration, this latter process being called atresia. Even if atresia involves apoptosis, its mechanism is not well understood. The objective of this study was to analyze global gene expression in pig granulosa cells of ovarian follicles during atresia. The transcriptome analysis was performed on a 9,216 cDNA microarray to identify gene networks and candidate genes involved in pig ovarian follicular atresia. We found 1,684 significantly regulated genes to be differentially regulated between small healthy follicles and small atretic follicles. Among them, 287 genes had a fold-change higher than two between the two follicle groups. Eleven genes (DKK3, GADD45A, CAMTA2, CCDC80, DAPK2, ECSIT, MSMB, NUPR1, RUNX2, SAMD4A, and ZNF628) having a fold-change higher than five between groups could likely serve as markers of follicular atresia. Moreover, automatic confrontation of deregulated genes with literature data highlighted 93 genes as regulatory candidates of pig granulosa cell atresia. Among these genes known to be inhibitors of apoptosis, stimulators of apoptosis, or tumor suppressors INHBB, HNF4, CLU, different interleukins (IL5, IL24), TNF-associated receptor (TNFR1), and cytochrome-c oxidase (COX) were suggested as playing an important role in porcine atresia. The present study also enlists key upstream regulators in follicle atresia based on our results and on a literature review. The novel gene candidates and gene networks identified in the current study lead to a better understanding of the molecular regulation of ovarian follicular atresia.

    The French national neonatal screening program for congenital hypothyroidism (CH) was initiated in 1978. The purpose of this study was to ascertain the incidence of congenital extrathyroid anomalies (ETAs) among the infants with congenital hypothyroidism (CH) and to compare it with the Northeastern France Birth Defect Monitoring System data from 1979 to 1996. Among 129 CH infants on whom adequate data were available, 20 infants (15.5%) had associated congenital anomalies. Eight out of 76 infants with persistent CH had ETAs (10.5%) whereas 12 out of 53 children with transient hypothyroidism had ETAs (22.6%, p < 0.05). Some additional anomalies were considerably more common than in the general population. Nine infants had congenital cardiac anomalies (6.9%). This rises the question if teratogenic effects active during organogenesis may affect simultaneously many organs, including the developing thyroid, causing a relatively high percentage of CH infants with congenital ETAs.

    A case report of biliary atresia associated with preduodenal portal vein is presented with a review of 27 similar cases previously reported. The occurrence of associated anomalies in these 28 cases has a much higher frequency (82%) than coincidental association. They were associated with cardiovascular anomalies in 71%, polysplenia in 68%, malrotation of the intestine in 61%, situs inversus in 22% and duodenal atresia in 9%. Developmental anomaly is considered to participate strongly in the aetiology of biliary atresia combined with preduodenal portal vein.

    Atresia ani is the most common anorectal anomaly in small animals. In the present study, an anal stricture (atresia ani type I) in five 3 to 8 weeks old kittens and one 4 month old puppy was treated by balloon dilation. In 4 kittens and the puppy the stricture was eliminated permanently and without complications by a single intervention. Only the smallest kitten with the most severe stenosis developed a rectal fistula as a complication of repeated balloon dilation, which necessitated surgical correction. Balloon dilation proved to be an efficient therapeutic method for anal atresia type I, and can be recommended as the treatment of choice.

    In 80% of the patients presenting with deep-venous thrombosis (DVT), a risk factor can be identified. An absent or hypoplastic infrarenal vena cava is a rare risk factor for DVT in young adults. In these cases, the prevalence of congenital anomalies of the inferior vena cava (IVC) is estimated at 0.5% of the general population, up to 5% in young people. The association with coagulopathy increases the risk of DVT. We report a case of a young man who presented with a massive caval and iliofemoral-popliteal thrombosis in presence of the agenesis of retrohepatic inferior vena cava and atresia of the left renal vein. Open thrombectomy and caval reconstruction with a polytetrafluoroethylene graft were performed. Surgical option with vein reconstruction was preferred to prevent new episodes of thrombosis and the risk of acute renal failure.

    Objective: To assess the natural history of congenital myopathies (CMs) due to different genotypes. Methods: Retrospective cross-sectional study based on case-note review of 125 patients affected by CM, followed at a single pediatric neuromuscular center, between 1984 and 2012. Results: Genetic characterization was achieved in 99 of 125 cases (79.2%), with RYR1 most frequently implicated (44/125). Neonatal/infantile onset was observed in 76%. At birth, 30.4% required respiratory support, and 25.2% nasogastric feeding. Twelve percent died, mainly within the first year, associated with mutations in ACTA1, MTM1, or KLHL40. All RYR1-mutated cases survived and did not require long-term ventilator support including those with severe neonatal onset; however, recessive cases were more likely to require gastrostomy insertion (p = 0.0028) compared with dominant cases. Independent ambulation was achieved in 74.1% of all patients; 62.9% were late walkers. Among ambulant patients, 9% eventually became wheelchair-dependent. Scoliosis of variable severity was reported in 40%, with 1/3 of (both ambulant and nonambulant) patients requiring surgery. Bulbar involvement was present in 46.4% and required gastrostomy placement in 28.8% (at a mean age of 2.7 years). Respiratory impairment of variable severity was a feature in 64.1%; approximately half of these patients required nocturnal noninvasive ventilation due to respiratory failure (at a mean age of 8.5 years). Conclusions: We describe the long-term outcome of a large cohort of patients with CMs. While overall course is stable, we demonstrate a wide clinical spectrum with motor deterioration in a subset of cases. Severity in the neonatal/infantile period is critical for survival, with clear genotype-phenotype correlations that may inform future counseling. PMID:25428687

    Congenital heart malformations are the most common of all birth defects, affecting 0.5-1% of all live births. Some of these malformations are due to genetic anomalies. Patterns of autosomal dominant, autosomal recessive and X-linked inheritance have been described. Mitochondrial inheritance and chromosomal anomalies can also be responsible for congenital heart malformations. Several genes for congenital heart defects have been identified. We review current knowledge on the genetic etiology of congenital heart disease.

    Jacobsen syndrome is a rare chromosomal disorder due to terminal 11q deletion. Prominent features are growth and psychomotor retardation, trigonocephaly and a characteristic facial dysmorphism, but many different abnormalities have been reported. We present the case of a preterm male. Prenatal ultrasonography was suspicious for duodenal atresia. At birth, the boy presented the craniofacial features typical of Jacobsen syndrome, together with diffusely spread petechiae and talipes equinovarus. Hemogram revealed pancytopenia. Ultrasound examination showed left renal agenesis and confirmed the duodenal atresia. Cerebral computed tomography scan, electroencephalogram and cardiac studies showed no abnormalities. Annular pancreas was found during surgery to correct the duodenal atresia. The karyotype was 46,XY,del(11)(q23.2 --> qter), which confirmed Jacobsen syndrome.A wide spectrum of clinical features is described in Jacobsen syndrome, with phenotype-karyotype correlation. This is the first report of duodenal atresia and annular pancreas.

    Eosinophilic esophagitis (EoE) is a relatively new condition resulting in dysphagia or symptoms resembling gastroesophageal reflux disease, symptoms that also are common in patients with a history of esophageal atresia. We present 2 patients with persistent dysphagia after repair of esophageal atresia that was caused by EoE. Although the exact etiology and pathogenesis of EoE remain unclear, it is now generally accepted that it is the result of a T-helper cell 2-type immune response with a crucial role for the eosinophil-specific chemotaxis factor eotaxin 3 and eosinophils. Because there are genetic similarities between esophageal atresia and EoE, we speculate that patients with esophageal atresia are at increased risk for developing EoE.

    An acquired ileal atresia is a rare occurrence. A 3-week-old neonate is presented, who developed postnatally a type 2 ileal atresia and an ileal stenosis within a pre-existing internal hernia secondary to an adhesion band. The literature reports a total of eight cases (4 females) with acquired ileal atresia in babies ranging in age from 3 weeks to 2 years (median 4 months). Mechanical forces (eg, adhesion band, intussusception and volvulus) onto the intestine are most frequently (75%) implicated as the primary event. The distal ileum is most often affected and a type 3A atresia is identified in six of eight (75%) cases. PMID:24225736

    The purpose of this study was to evaluate the prevalence and type of lung function disorders in Danish farmers. Three samples of farmers were drawn from a group of unselected farmers who had participated in an epidemiological study. Group I (47 persons) was a sample of the 8% of all farmers who had reported that they had asthma; group II (63 persons) was a sample of the 28% of farmers who had had wheezing, shortness of breath, or cough without phlegm; and group III (34 persons) a sample of the farmers (64% of the total) who had no asthma and no respiratory symptoms. The farmers with symptoms (groups I and II) had low mean levels of FEV1 and high values for residual volume, whereas the symptomless farmers had normal lung function and no airways obstruction. The proportion of farmers with an FEV1 below the 95% confidence limit for predicted values was 43% in group I and 23% in group II; there were none in group III. Bronchial hyperreactivity to histamine occurred in 96% of asthmatic farmers, 67% of farmers with wheezing or shortness of breath, and 59% of symptomless farmers. A low level of FEV1 was associated with the number of years in pig farming and bronchial hyperreactivity in group II but not group I or III. Most of the bronchial hyperreactivity was explained in the multiple regression analysis by a low FEV1, though this was significant only for farmers in group II. Thus farmers who reported asthma, wheezing, shortness of breath, or a dry cough in general had airways obstruction with an increased residual volume, whereas symptomless farmers had normal lung function. Severe bronchial hyperreactivity was mostly explained by a diagnosis of asthma and poor lung function, though some farmers with normal lung function and no respiratory symptoms had increased bronchial reactivity.

    Aims: In 1955, Professor Morio Kasai first performed a hepatic portoenterostomy. Since then, the procedure has changed the lives of children with biliary atresia (BA). We report our initial experience in performing “extended” Kasai portoenterostomy (KPE), a modification of the original procedure. Materials and Methods: Since 2013, we have used the technique of “extended KPE” and prospectively recorded data on all children undergoing this operation. Data on demographics, clinical features, liver function tests, and perioperative cholangiogram findings were collected. Outcome of KPE was measured by Jaundice Disappearance Rate (JDR) and Native Liver Survival Rate (NLSR). We present our preliminary results from a 30-month period (February 2013 to May 2015). Results: Thirty-one children underwent KPE during this period (19 males) and only 1 child had biliary atresia splenic malformation (BASM). The mean age at KPE was 73 ± 24 days. Five (16.1%) children were more than 90 days old at the time of KPE. Fourteen children cleared jaundice (JDR 45.2%). Eleven (35.5%) children developed episodes of cholangitis, of whom 8 had early cholangitis (within 3 months of the operation). The proportion of children who survived with their own liver 6 months after KPE (NLSR) was 84.2%. Of those children older than 90 days, 2 cleared jaundice and have survived with their native livers for more than 16 months. Conclusion: In our preliminary report of 31 children, we conclude that the extended KPE leads to increased jaundice clearance and improved NLSR in children with BA. PMID:27046977

    The proximal q arm of chromosome 15 contains breakpoint regions BP1-BP5 with the classic deletion of BP1-BP3 best known to be associated with Prader-Willi and Angelman syndromes. The region is approximately 500 kb and microdeletions within the BP1-BP2 region have been reported in patients with developmental delay, behavioral abnormalities, and motor apraxia as well as dysmorphic features including hypertelorism, cleft or narrow palate, ear abnormalities, and recurrent upper airway infections. We report two patients with unique, never-before-reported 15q11.2 BP1-2 microdeletion syndrome findings, one with proximal esophageal atresia and distal tracheoesophageal fistula (type C) and one with congenital cataracts. Cataracts have been described in Prader-Willi syndrome but we could not find any description of cataracts in Angelman syndrome. Esophageal atresia and tracheoesophageal fistula have not been reported to our knowledge in either syndrome. A chance exists that both cases are sporadic birth defects; however, the findings of the concomitant microdeletion cannot be overlooked as a possible cause. Based on our review of the literature and the presentation of our patients, we recommend that esophageal atresia and distal tracheoesophageal fistula as well as congenital cataracts be included in the phenotypic spectrum of 15q11.2 BP1-2 microdeletion syndrome.

    A case of congenital duplication (monocephalus dipygus) in a goat is described. Two pelvis and four pelvic limbs were observed in the kid. Conjoined or fused symmetric twins were diagnosed. Associated abnormalities were cleft palate and anal atresia. Most of the classically recognized teratogens were ruled out by history and serology. However, progenitors were related in the second degree. Thus, genetic factors could be suspected in this case. To the authors' best knowledge, this is the first report of monocephalus dipygus in a goat.

    The following is a report on a congenital vaginal malformation, imperforate vagina, in the common marmoset (Callithrix jacchus). This anomaly was observed for the first time in an adult female in our research colony. There was no uterine and vaginal aplasia or atresia in her grossly normal genital tract. The plasma progesterone concentration suggested that the ovarian cycle had ceased. However, this may not be related to a functional anomaly, but rather to suppressed ovulation resulting from subordination to cagemates considering the various stages of follicular development observed.

    The surgical treatment of patients with extracardiac structural anomalies and congenital heart disease often carries major risk and remains a challenging field. An appropriate, solid treatment plan should be developed during the early phase with interactive intelligence sharing between a pediatric surgery team and congenital heart surgery team. As the top of the chain of command, the role of a neonatologist is important. This article reviews the history of surgery for congenital heart disease and the progress of the Japan Congenital Cardiovascular Surgery Database. Finally, as an example of a combination of diseases, the clinical course and intelligence sharing during treatment of a patient with biliary atresia requiring living-donor liver transplantation and hypoplastic left heart syndrome is reported. The National Quality Forum provided structural measures, process measures, and outcome measures for congenital heart surgery. Structural measures provided by the National Quality Forum included participation in a preoperative multidisciplinary conference. To improve the outcome of surgical treatment of patients with congenital heart disease and extracardiac structural anomalies, the importance of a preoperative multidisciplinary conference involving not only pediatric surgeons, pediatric cardiologists, and pediatric cardiac surgeons but also neonatologists, anesthesiologists, and nurses cannot be overemphasized.

    2013-08-01

    The association of pulmonary atresia and ventricular septal defect (PA/VSD) can be considered the most severe form of tetralogy of Fallot. The main feature of this congenital heart disease is represented by discontinuity between the right ventricle and pulmonary trunk or its branches; the anatomy of central pulmonary arteries is often abnormal, consequently the type and the amount of sources of pulmonary blood flow are variable. Due to evolution in surgical techniques, definitive correction is now also considered in more complex cases. A small rate of unoperated patients with PA/VSD can survive until adulthood and the arterial blood supply to the lungs, provided by major aorto-pulmonary collateral arteries (MAPCAs), is one of the main determinants of survival. We report two unoperated cases of PA/VSD and MAPCAs with long-term survival. Giant MAPCAs can occasionally be found by chest radiography in adults with unrepaired PA/VSD. Moreover, non-invasive assessment of the pulmonary arterial bed with computer tomography or MRI is helpful in these patients during follow-up. Finally, we discuss the use of oral anticoagulants and/or 5-phosphodiesterase inhibitors in these patients.

    Cor triatriatum sinister (CTS) is a rare congenital abnormality. Clinical presentation of patients with CTS mainly depends on the anatomic features of membrane and may vary from mild or moderate symptoms mimicking mitral stenosis to more severe and complicated cardioembolic stroke or a new onset heart failure. We herein have reported on a young male who presented with the signs and symptoms of mitral stenosis and was diagnosed as CTS with gradient on the orifice of the membrane after transthrocacic echocardiography. Computerized tomographic angiography revealed that the patient had unilateral, left sided pulmonary arterial hypoplasia and pulmonary vein atresia, with only the right pulmonary veins draining into the left atrial chamber. Further cardiac imaging by either computed tomography or magnetic resonance imaging is necessary in order to seek accompanying cardiac and vascular abnormalities. Patients with CTS have improved short and long term survival rates if CTS and accompanying abnormalities are surgically treated before the disease is complicated with heart failure, pulmonary hypertension, stroke and etc. PMID:27899867

    Esophageal atresia (EA) is a congenital defect of the esophagus involving the interruption of the esophagus with or without connection to the trachea (tracheoesophageal fistula [TEF]). EA/TEF may occur as an isolated anomaly, may be part of a complex of congenital defects (syndromic), or may develop within the context of a known syndrome or association. The molecular mechanisms underlying the development of EA are poorly understood. It is supposed that a combination of multigenic factors and epigenetic modification of genes play a role in its etiology. The aim of our work was to assess the human gene expression microarray study in esophageal tissue samples. Total RNA was extracted from 26 lower pouches of esophageal tissue collected during thoracoscopic EA repair in neonates with the isolated (IEA) and the syndromic form (SEA). We identified 787 downregulated and 841 upregulated transcripts between SEA and controls, and about 817 downregulated and 765 upregulated probes between IEA and controls. Fifty percent of these genes showed differential expression specific for either IEA or SEA. Functional pathway analysis revealed substantial enrichment for Wnt and Sonic hedgehog, as well as cytokine and chemokine signaling pathways. Moreover, we performed reverse transcription polymerase chain reaction study in a group of SHH and Wnt pathways genes with differential expression in microarray profiling to confirm the microarray expression results. We verified the altered expression in SFRP2 gene from the Wnt pathway as well as SHH, GLI1, GLI2, and GLI3 from the Sonic hedgehog pathway. The results suggest an important role of these pathways and genes for EA/TEF etiology.

    Tetralogy of Fallot (TOF) with pulmonary atresia (PA) and multiple aortopulmonary collaterals (MAPCAs) is a rare and severe form of congenital heart disease with poor prognosis. Aortopulmonary collaterals expose pulmonary arterioles to systemic pressure resulting in pulmonary hypertension (PH). To date, reports regarding the role of PH medications in this population are sparse. The objective of this study was to assess the effect of PH medications in patients with TOF, PA and MAPCAs or similar anatomy, with emphasis on symptoms, echocardiography and invasive hemodynamics. A retrospective review was performed for patients at a single tertiary care pediatric center. Twelve of 66 patients were treated with PH medications (18 %), and eight of these patients had adequate follow-up for further analysis. Median age at last follow-up was 6 years (range 1.4-21 years). Median length of therapy with PH medication was 4 years (range 0.3-17 years). PH medications included sildenafil, bosentan, ambrisentan, inhaled treprostinil and prostacyclin infusion. PH therapy was associated with improvement in symptoms in all patients and improvement in PH by hemodynamic measures in the majority of patients. All patients underwent at least one cardiac intervention by catheterization or surgery while taking PH medication. Two patients died from non-PH-related causes. The remaining six patients are alive and remain on PH medication. This review indicates that PH medications are well tolerated by this patient group and provide symptomatic improvement. Further studies are required to determine whether PH medications provide long-term survival benefit for patients with complex congenital heart disease.

    Although most often recognized in neonates and young children, congenital cystic adenomatoid malformation of the lung (CCAM) occasionally appears in later years. Three patients, aged 35, 24, and 7 years, are reported. Chest radiographs in each case suggested a localized patchy density, a cystic mass, or a multicystic mass, but computed tomography (CT) best demonstrated the cystic and solid components while ruling out bronchiectasis or major bronchial obstruction. Bronchography contributed no further diagnostic information compared with CT. Each patient underwent lobectomy. Histologically, the characteristic overgrowth of bronchiolar elements replacing normal parenchymal architecture was accompanied by some superimposed inflammatory change.

    Abstract. Coincidental cyanotic congenital heart disease and pheochromocytoma is uncommon, although some cases have been reported. We describe a girl aged 15 yr and 11 mo with pheochromocytoma and tricuspid atresia treated by performing the Fontan surgery. The patient did not have any specific symptoms of syndrome related to pheochromoytoma or a family history of pheochromocytoma. During cardiac catheterization, her blood pressure increased markedly, and an α-blocker was administered. Catecholamine hypersecretion was observed in the blood and urine, and abdominal computed tomography revealed a tumor in the right adrenal gland. Scintigraphy showed marked accumulation of 123I-metaiodobenzylguanidine in the tumor, which led to a diagnosis of pheochromocytoma. We did not detect any germline mutations in the RET, VHL, SDHB, SDHD, TMEM127, or MAX genes. This patient had experienced mild systemic hypoxia since birth, which may have contributed to the development of pheochromocytoma. PMID:27212797

    Congenital middle ear malformations are rare. Most part of them are usually associated with other malformations, such as aural atresia, microtia, and dysmorphic craniofacial features. A clinical case of a 24-year-old male with a right-sided conductive hearing loss since his childhood, without craniofacial malformation, is presented. He was proposed for exploratory tympanotomy under the suspicious diagnosis of otosclerosis. The surgery revealed an abnormal location of stapes' superstructure, which was attached to the promontory and had an isolated and mobile osseous footplate in the oval window. A stapes prosthesis was inserted and resulted in closure of the air-bone gap by 25 dB. A review of the literature was also performed using MEDLINE. Two theories diverge on the embryologic origin of the stapes. Our findings seem to be in favour of the theory that defines two different embryologic origins to the stapes. PMID:27648330

    The authors compared the serum and bronchial concentration of amoxycillin administered alone and in association with carboxymethylcysteine. The determinations were carried out in 10 patients affected with exacerbated acute and chronic bronchopneumopathies, treated first with amoxycillin alone (15 g/day in 3 administrations) and then with amoxycillin at the same dosage and carboxymethylcysteine (450 mg/day in 3 administrations). The bronchial secretions were collected during bronchoscopy performed 2 hours after the last administration of antibiotic. The bronchial secretion values of amoxycillin administered alone varied from 0.92 mcg/ml to 1.88 mcg/ml with a mean value of 1.44 mcg/ml. The percentage ratio between levels in bronchial secretion and levels in the serum varied from 12.7 to 36.1 with a mean value of 23.2. The administration of the amoxycillin-fluidizing agent association determined a statistically significant increase of the antibiotic levels in the bronchial secretions, varying from 1.26 mcg/ml to 6.39 mcg/ml, with a percentage ratio from 19.6 to 103.0.

    Most people who abuse alcohol are cigarette smokers. Previously, we have shown that malondialdehyde, an inflammation product of lipid peroxidation, and acetaldehyde, a component of both ethanol metabolism and cigarette smoke, form protein adducts that stimulate protein kinase C (PKC) activation in bronchial epithelial cells. We have also shown that PKC can regulate bronchial epithelial cell wound repair. We hypothesize that bovine serum albumin adducted with malondialdehyde and acetaldehyde (BSA-MAA) decreases bronchial epithelial cell wound repair via binding to scavenger receptors on bronchial epithelial cells. To test this, confluent monolayers of bovine bronchial epithelial cells were grown in serum-free media prior to wounding the cells. Bronchial epithelial cell wound closure was inhibited in a dose-dependent manner (up to 60%) in the presence of BSA-MAA than in media treated cells (Laboratory of Human Carcinogenesis [LHC]-9-Roswell Park Memorial Institute [RPMI]). The specific scavenger receptor ligand, fucoidan, also stimulated PKC activation and decreased wound repair. Pretreatment with fucoidan blocked malondialdehyde-acetaldehyde binding to bronchial epithelial cells. When bronchial epithelial cells were preincubated with a PKC alpha inhibitor, Gö 6976, the inhibition of wound closure by fucoidan and BSA-MAA was blocked. Western blot demonstrated the presence of several scavenger receptors on bronchial epithelial cell membranes, including SRA, SRBI, SRBII, and CD36. Scavenger receptor-mediated activation of PKC alpha may function to reduce wound healing under conditions of alcohol and cigarette smoke exposure where malondialdehyde-acetaldehyde adducts may be present.

    Eosinophilic inflammation and remodeling of the airways including subepithelial fibrosis and myofibroblast hyperplasia are characteristic pathological findings of bronchial asthma. Epithelial to mesenchymal transition (EMT) plays a critical role in airway remodelling. In this study, we hypothesized that infiltrating eosinophils promote airway remodelling in bronchial asthma. To demonstrate this hypothesis we evaluated the effect of eosinophils on EMT by in vitro and in vivo studies. EMT was assessed in mice that received intra-tracheal instillation of mouse bone marrow derived eosinophils and in human bronchial epithelial cells co-cultured with eosinophils freshly purified from healthy individuals or with eosinophilic leukemia cell lines. Intra-tracheal instillation of eosinophils was associated with enhanced bronchial inflammation and fibrosis and increased lung concentration of growth factors. Mice instilled with eosinophils pre-treated with transforming growth factor(TGF)-β1 siRNA had decreased bronchial wall fibrosis compared to controls. EMT was induced in bronchial epithelial cells co-cultured with human eosinophils and it was associated with increased expression of TGF-β1 and Smad3 phosphorylation in the bronchial epithelial cells. Treatment with anti-TGF-β1 antibody blocked EMT in bronchial epithelial cells. Eosinophils induced EMT in bronchial epithelial cells, suggesting their contribution to the pathogenesis of airway remodelling.

    With increasing incrimination of viruses, plants, and drugs as causes of ovine congenital defects, concerted efforts are required to identify environmental teratogens. Expanding knowledge of congenital defects requires studying as many defective lambs as possible; recording and documenting; detailed diagnostic examinations; genetic analyses and chromosomal examinations, whenever possible; and field investigations. Adopting standardized classification, terminology, and diagnostic procedures should improve descriptions, diagnoses, and interdisciplinary exchange of information. That, in turn, should improve our knowledge of and diagnosis of congenital defects of sheep in the future. Finally, veterinary clinicians and diagnosticians are encouraged to take an interest in congenital defects and teratology.

    2014-09-01

    Diagnosis of biliary atresia (BA) in infants presenting with cholestatic jaundice (CJ) requires exploratory surgery with cholangiography. However, the lack of a standardized approach to preoperative evaluation of infants with CJ can lead to a high number of negative surgical explorations. We reviewed our experience with CJ and BA to determine preoperative variables that might reliably identify BA. Infants explored for possible BA over a 5-year period were retrospectively reviewed. Preoperative clinical indices and liver biopsy results were reviewed. Statistical analysis was conducted by Student's t test and Fisher's exact test (P < 0.05). Twenty patients were identified, 10 with BA and 10 without (50% negative exploration rate). Nuclear cholescintigraphy (HIDA) excretion into the gastrointestinal tract was absent in all BA and in 8 of 10 without BA. Hepatomegaly was more common in the BA group (OR = 9.3, P = 0.07). BA had higher mean (± standard error) serum gamma-glutamyl transpeptidase levels (542 ± 130 vs 139 ± 25.8 U/L in non-BA, P = 0.03). There were insignificant differences in sex, type of feeding, TPN exposure and sepsis between the two groups. Although our small sample size limits conclusions, we suggest screening infants with CJ by measuring GGT levels, absence of hepatomegaly, presence of cholic stools and/or excretion on HIDA scan to undergo pecutaneous liver biopsy given the lower likelihood of BA necessary.

    Trisomy 18 is a common chromosomal aberration syndrome involving growth impairment, various malformations, poor prognosis, and severe developmental delay in survivors. Although esophageal atresia (EA) with tracheoesophageal fistula (TEF) is a potentially fatal complication that can only be rescued through surgical correction, no reports have addressed the efficacy of surgical intervention for EA in patients with trisomy 18. We reviewed detailed clinical information of 24 patients with trisomy 18 and EA who were admitted to two neonatal intensive care units in Japan and underwent intensive treatment including surgical interventions from 1982 to 2009. Nine patients underwent only palliative surgery, including six who underwent only gastrostomy or both gastrostomy and jejunostomy (Group 1) and three who underwent gastrostomy and TEF division (Group 2). The other 15 patients underwent radical surgery, including 10 who underwent single-stage esophago-esophagostomy with TEF division (Group 3) and five who underwent two-stage operation (gastrostomy followed by esophago-esophagostomy with TEF division) (Group 4). No intraoperative death or anesthetic complications were noted. Enteral feeding was accomplished in 17 patients, three of whom were fed orally. Three patients could be discharged home. The 1-year survival rate was 17%: 27% in those receiving radical surgery (Groups 3 and 4); 0% in those receiving palliative surgery (Groups 1 and 2). Most causes of death were related to cardiac complications. EA is not an absolute poor prognostic factor in patients with trisomy 18 undergoing radical surgery for EA and intensive cardiac management.

    Six patients aged 1.5 to 4 years with type 13 tricuspid atresia underwent extracardiac bicavopulmonary repair. This corrective procedure comprises control of palliative aorto-pulmonary anastomosis, the construction of an anastomosis between the superior vena cava and right pulmonary artery and the interposition of an extracardiac tube of autologous pediculated pericardium between the inferior vena cava and the main pulmonary artery. This tube, fashioned from a rectangular flap, remains attached along its right border, conserving its vascular pedicle with the pericardium. Its diameter is calibrated to that of the inferior vena cava. The postoperative course was uncomplicated: all children survived. Assisted respiration was discontinued 24 to 36 hours after surgery, and the pleural drains withdrawn after 48 to 72 hours. The rhythm remained sinusal. Central venous pressure ranged from 8 to 12 mmHg. Peripheral arterial situation was over 95%. At follow-up at 3 to 15 months, the children were very active, reflecting good exercise capacity. Holter monitoring was normal. Saturation was 94 to 97%. Doppler echocardiography showed laminar blood flow. This technique insures good venous drainage without any prosthetic thrombogenic material. In addition, the pediculated pericardium conserves a potential for growth, justifying its use in small children. Long-term evaluation is essential but the initial results are encouraging and encourage perseverance with this method.

    Biliary atresia (BA) is a progressive, inflammatory, and fibrosclerosing cholangiopathy in infants that results in obstruction of both extrahepatic and intrahepatic bile ducts. It is the most common cause for pediatric liver transplantation. In contrast, the sea lamprey undergoes developmental BA with transient cholestasis and fibrosis during metamorphosis, but emerges as a fecund adult with steatohepatitis and fibrosis in the liver. In this paper, we present new histological evidence and compare the sea lamprey to existing animal models to highlight the advantages and possible limitations of using the sea lamprey to study the etiology and compensatory mechanisms of BA and other liver diseases. Understanding the signaling factors and genetic networks underlying lamprey BA can provide insights into BA etiology and possible targets to prevent biliary degeneration and to clear fibrosis. In addition, information from lamprey BA can be used to develop adjunct treatments for patients awaiting or receiving surgical treatments. Furthermore, the cholestatic adult lamprey has unique adaptive mechanisms that can be used to explore potential treatments for cholestasis and nonalcoholic steatohepatitis (NASH). PMID:26101777

    Biliary atresia (BA) is a rapidly progressive and destructive fibrotic disorder of unknown etiology affecting the extrahepatic biliary tree of neonates. Epidemiological studies suggest that an environmental factor, such as a virus or toxin, is the cause of the disease, although none have been definitively established. Several naturally occurring outbreaks of BA in Australian livestock have been associated with the ingestion of unusual plants by pregnant animals during drought conditions. We used a biliary secretion assay in zebrafish to isolate a previously undescribed isoflavonoid, biliatresone, from Dysphania species implicated in a recent BA outbreak. This compound caused selective destruction of the extrahepatic, but not intrahepatic, biliary system of larval zebrafish. A mutation that enhanced biliatresone toxicity mapped to a region of the zebrafish genome that has conserved synteny with an established human BA susceptibility locus. The toxin also caused loss of cilia in neonatal mouse extrahepatic cholangiocytes in culture and disrupted cell polarity and monolayer integrity in cholangiocyte spheroids. Together, these findings provide direct evidence that BA could be initiated by perinatal exposure to an environmental toxin. PMID:25947162

    Choanal atresia (CA) is a common nasal craniofacial malformation in New World domestic camelids (alpaca and llama). CA results from abnormal development of the nasal passages and is especially debilitating to newborn crias. CA in camelids shares many of the clinical manifestations of a similar condition in humans (CHARGE syndrome). Herein we report on the regulatory gene CHD7 of alpaca, whose homologue in humans is most frequently associated with CHARGE. Sequence of the CHD7 coding region was obtained from a non-affected cria. The complete coding region was 9003 bp, corresponding to a translated amino acid sequence of 3000 aa. Additional genomic sequences corresponding to a significant portion of the CHD7 gene were identified and assembled from the 2x alpaca whole genome sequence, providing confirmatory sequence for much of the CHD7 coding region. The alpaca CHD7 mRNA sequence was 97.9% similar to the human sequence, with the greatest sequence difference being an insertion in exon 38 that results in a polyalanine repeat (A12). Polymorphism in this repeat was tested for association with CA in alpaca by cloning and sequencing the repeat from both affected and non-affected individuals. Variation in length of the poly-A repeat was not associated with CA. Complete sequencing of the CHD7 gene will be necessary to determine whether other mutations in CHD7 are the cause of CA in camelids.

    Background: Isolated oesophageal atresia without tracheo-oesophageal fistula represents a major challenge for most paediatric surgeons. Here, we present our experience with six neonates with isolated oesophageal atresia who successfully underwent immediate primary anastomosis using multiple Livaditis circular myotomy. Materials and Methods: All six neonates were gross type A isolated oesophageal atresia (6%), from among 102 neonates with oesophageal atresia, treated between January 2009 and December 2013. Five neonates were female; one was male. The mean birth weight was 2300 (range 1700-3100) g. Results: All six neonates successfully underwent immediate primary anastomosis using multiple myotomies (mean 3; range 2-4) within 10 (median 3) days after birth. The gap under traction ranged from 6 to 7 cm. One neonate died of a major cardiac anomaly. Another neonate was lost to follow-up after being well for 3 months. Three anastomotic strictures were treated with balloon dilatation, and four anastomotic leaks were treated conservatively. The mean duration of follow-up was 33 months. Conclusions: To treat isolated oesophageal atresia, an immediate primary anastomosis can be achieved using multiple myotomies. Although, this approach is associated with high complication rates, as are other similar approaches, these complications can be overcome. PMID:26712295

    As multi-slice CT develops, there are great expectations for an automatic and computer-support diagnoses. This research is on bronchial area which is composed of the bronchial wall regions and the air regions in the internal bronchial tube. Since to diagnose this is difficult, support diagnosis using CT images is desired. The thickness of bronchial wall changes as the airway of early lung cancer, bronchial asthma and the bronchial enhancing syndrome and others change into a malignant state. These changes are detected and the thickness of bronchial wall becomes important information. In this research, the extraction accuracy of the algorithm for bronchial wall evaluation is good.

    Kartagener syndrome is an autosomal recessive disorder characterized by primary ciliary dyskinesia accompanied by sinusitis, bronchiectasis, and situs inversus. Synchronous extrahepatic biliary atresia and Kartagener syndrome are very rare. During the preoperative preparation of patients with Kartagener syndrome, special attention is required for the respiratory and cardiovascular system. It is important to provide suitable anaesthetic management to avoid problems because of ciliary dysfunction in the perioperative period. Further, maintaining an effective pain control with regional anaesthetic methods reduces the risk of pulmonary complications. Infants with biliary atresia operated earlier have a higher chance of survival. Hepatic dysfunction and decrease in plasma proteins are important for the kinetics of drugs. In this presentation, the anaesthetic management of patients with synchronous Kartagener syndrome and biliary atresia, both of which are rare diseases, is evaluated. PMID:27366497

    Congenital hemangiopericytoma (HPC) is a rare mesenchymal tumor with less aggressive behavior and a more favorable prognosis than similar tumors in adults. Multifocal presentation is even less common than isolated HPC and hence its clinical and histologic recognition may be challenging. A newborn infant with multifocal congenital HPC causing severe deformity but with a favorable outcome after chemotherapy and surgical removal is reported.

    Bronchial artery dilatation and aneurysm formation is a potential complication of local inflammation, especially in bronchiectasis. When the bronchial artery has an ectopic origin from the inferior segment of the aortic arch, aneurysms may mimick aortic aneurysms. Despite this particular location, endovascular treatment is possible. We report two such aneurysms that were successfully embolized with steel coils.

    Persistent left superior vena cava (LSVC) is a relatively frequent finding in congenital cardiac malformation. The scope of the study was to analyze the timing of diagnosis of persistent LSVC, the timing of diagnosis of associated anomalies of the coronary sinus, and the global impact on morbidity and mortality of persistent LSVC in children with congenital heart disease after cardiac surgery. Retrospective analysis of a cohort of children after cardiac surgery on bypass for congenital heart disease. Three hundred seventy-one patients were included in the study, and their median age was 2.75 years (IQR 0.65-6.63). Forty-seven children had persistent LSVC (12.7 %), and persistent LSVC was identified on echocardiography before surgery in 39 patients (83 %). In three patients (6.4 %) with persistent LSVC, significant inflow obstruction of the left ventricle developed after surgery leading to low output syndrome or secondary pulmonary hypertension. In eight patients (17 %), persistent LSVC was associated with a partially or completely unroofed coronary sinus and in two cases (4 %) with coronary sinus ostial atresia. Duration of mechanical ventilation was significantly shorter in the control group (1.2 vs. 3.0 days, p = 0.04), whereas length of stay in intensive care did not differ. Mortality was also significantly lower in the control group (2.5 vs. 10.6 %, p = 0.004). The results of study show that persistent LSVC in association with congenital cardiac malformation increases the risk of mortality in children with cardiac surgery on cardiopulmonary bypass. Recognition of a persistent LSVC and its associated anomalies is mandatory to avoid complications during or after cardiac surgery.

    Highlights: • The RRV infected group showed cholestasis, retardation and extrahepatic biliary atresia. • miR-222 was highly expressed, and PPP2R2A was inhibited in the murine biliary atresia model. • miR-222 profoundly modulated the process of fibrosis in the murine biliary atresia model. • miR-222 might represent a potential target for improving biliary atresia prognosis. - Abstract: microRNA-222 (miR-222) has been shown to initiate the activation of hepatic stellate cells, which plays an important role in the pathogenesis of liver fibrosis. The aim of our study was to evaluate the role of miR-22 in a mouse model of biliary atresia (BA) induced by Rhesus Rotavirus (RRV) infection. New-born Balb/c mice were randomized into control and RRV infected groups. The extrahepatic bile ducts were evaluated. The experimental group was divided into BA group and negative group based on histology. The expression of miR-222, protein phosphatase 2 regulatory subunit B alpha (PPP2R2A), proliferating cell nuclear antigen (PCNA) and phospho-Akt were detected. We found that the experimental group showed signs of cholestasis, retardation and extrahepatic biliary atresia. No abnormalities were found in the control group. In the BA group, miR-222, PCNA and Akt were highly expressed, and PPP2R2A expression was significantly inhibited. Our findings suggest that miR-222 profoundly modulated the process of fibrosis in the murine BA model, which might represent a potential target for improving BA prognosis.

    Congenital parenchymal lung malformations have an estimated incidence at 1:25,000-1:35,000 births. We present a case of this rare congenital abnormality in a 38 year-old male, review the current literature with discussion of proposed causes, malignant potential, and management strategies. A 38-year-old white male presented with a 4-day history of chronic stable hemoptysis. Social history was notable for a 50-pack-year active smoking history and remote heavy alcohol consumption. Physical examination was normal. Chest radiograph revealed an ill defined right lower lobe infiltrate. Chest computed tomography demonstrated an irregular, thin-walled, cystic lesion with adjacent nodularity and calcifications. The patient received a right lower lobectomy. Pathologic specimen demonstrated a 10-cm, mostly thin-walled cyst with features suggestive of a congenital cyst adenomatoid malformation and areas of adenocarcinoma (mixed subtype with acinar and bronchioloalveolar patterns). Congenital cyst adenomatoid malformations have recently been renamed as congenital pulmonary airway malformations and are the most common type of congenital parenchymal lung malformations. Individuals typically present with recurrent pulmonary infections, pneumothorax, or hemoptysis. The development is controversial but believed to be a result of arrested development of the fetal bronchial tree during the sixth and seventh week of fetal development. Defects in thyroid transcription factor 1 have also been proposed. With the increasing use and image resolution of ultrasound in modern obstetric practice, congenital pulmonary airway malformations rarely go undetected into adulthood. Management remains controversial; however, most authors agree with early surgical excision.

    The paper presents the analysis of clinical case of endoscopic nasal breath restoration and elimination of the secondary cleft lip nasal deformity in 27 years old patient with unilateral choanal atresia and secondary nasal deformity after rhinocheiloplasty. Preoperative examination revealed the absence of nasal breathing on collateral side due to complete bone choanal atresia. Surgical treatment included endoscopic choanal repair, elimination of the secondary nasal deformity, septoplasty, conchotomy and lateroposition of the inferior conchae. The treatment resulted in nasal breath restoration and elimination of nasal deformity. Long-term follow-up at 1 and 12 months post-operatively proved stable positive aesthetic and functional results.

    Introduction The aim of this study was to stratify anastomotic strictures (AS) following esophageal atresia (EA) repair and to establish predictors for the need of dilations. Material and Methods A retrospective study on children operated on for EA between 2004 and 2014 was conducted. The stricture index (SI) was measured both radiologically (SIXR) and endoscopically (SIEND). A correlation analysis between the SI and the number of dilations was performed using Spearman's test and linear regression analysis. Results In this study, 40 patients were included: 35 (87.5%) presented with Gross's type C EA, 3 (7.5%) type A, 1 (2.5%) type B, and 1 (2.5%) type D. The mean follow-up time was 101 ± 71.1 months (range: 7.8-232.5, median: 97.6). The mean SIXR was 0.56 ± 0.16 (range: 0.15-0.86). The mean SIEND was 0.45 ± 0.22 (range: 0.15-0.85). Twenty-four patients (60%) underwent a mean of 2 endoscopic dilations (range: 1-9). The number of dilations was poorly correlated with SIXR, while significantly correlated with SIEND. Patients who did not need dilations had a SIEND < 0.33, patients who needed only one dilation had 0.33 ≤ SIEND < 0.44, and those with SIEND ≥ 0.44 needed two or more dilations. No significant association with other clinical variables was found. All patients were asymptomatic at the time of the first endoscopy. Conclusion SIEND is a useful tool to classify AS and can represent a predictor of the need for endoscopic dilation. The role of the SIEND becomes even more important as clinical characteristics have a low predictive value for the development of an AS and the need for subsequent endoscopic esophageal dilatations.

    Ectrodactyly-ectodermal dysplasia and clefting syndrome or "Lobster claw" deformity is a rare congenital anomaly that affects tissues of ectodermal and mesodermal origin. Nasolacrimal duct (NLD) obstruction with or without atresia of lacrimal passage is a common finding of such a syndrome. The authors report here even a rarer presentation of the syndrome which manifested as bilateral NLD obstruction and lacrimal fistula along with cleft lip and palate, syndactyly affecting all four limbs, mild mental retardation, otitis media, and sinusitis. Lacrimal duct obstruction and fistula were managed successfully with endoscopic dacryocystorhinostomy (DCR) which is a good alternative to lacrimal probing or open DCR in such a case.

    OBJECTIVES: To study the airway response and its mechanism to welding fumes in six welders with respiratory symptoms. METHODS: Methacholine and welding challenge tests were carried out. The concentration of welding fumes during the exposure test was measured. On two subjects who developed bronchoconstricition to welding challenge, additional tests were carried out including prick, patch, and inhalation challenges with metal salt solutions. RESULTS: Three subjects developed immediate bronchial reaction to exposure to welding fume; one to mild steel and stainless steel welding, another to mild steel and galvanised welding, and one only to galvanised welding. They all had a moderate to pronounced degree of non-specific bronchial hyperresponsiveness. The concentration of fumes during welding tests, particularly to galvanised welding, was high. An inhalation challenge test with zinc chloride salt solution in two subjects who reacted to galvanised welding was negative. Prick and patch tests with zinc chloride were also negative. CONCLUSION: The airway response to welding in these subjects is non-specific and is due to irritation rather than to sensitisation. PMID:9538358

    Giant congenital melanocytic nevus is usually defined as a melanocytic lesion present at birth that will reach a diameter ≥ 20 cm in adulthood. Its incidence is estimated in <1:20,000 newborns. Despite its rarity, this lesion is important because it may associate with severe complications such as malignant melanoma, affect the central nervous system (neurocutaneous melanosis), and have major psychosocial impact on the patient and his family due to its unsightly appearance. Giant congenital melanocytic nevus generally presents as a brown lesion, with flat or mammilated surface, well-demarcated borders and hypertrichosis. Congenital melanocytic nevus is primarily a clinical diagnosis. However, congenital nevi are histologically distinguished from acquired nevi mainly by their larger size, the spread of the nevus cells to the deep layers of the skin and by their more varied architecture and morphology. Although giant congenital melanocytic nevus is recognized as a risk factor for the development of melanoma, the precise magnitude of this risk is still controversial. The estimated lifetime risk of developing melanoma varies from 5 to 10%. On account of these uncertainties and the size of the lesions, the management of giant congenital melanocytic nevus needs individualization. Treatment may include surgical and non-surgical procedures, psychological intervention and/or clinical follow-up, with special attention to changes in color, texture or on the surface of the lesion. The only absolute indication for surgery in giant congenital melanocytic nevus is the development of a malignant neoplasm on the lesion. PMID:24474093

    Congenital hypothyroidism is the most common neonatal metabolic disorder and results in severe neurodevelopmental impairment and infertility if untreated. Congenital hypothyroidism is usually sporadic but up to 2% of thyroid dysgenesis is familial, and congenital hypothyroidism caused by organification defects is often recessively inherited. The candidate genes associated with this genetically heterogeneous disorder form two main groups: those causing thyroid gland dysgenesis and those causing dyshormonogenesis. Genes associated with thyroid gland dysgenesis include the TSH receptor in non-syndromic congenital hypothyroidism, and Gsα and the thyroid transcription factors (TTF-1, TTF-2, and Pax-8), associated with different complex syndromes that include congenital hypothyroidism. Among those causing dyshormonogenesis, the thyroid peroxidase and thyroglobulin genes were initially described, and more recently PDS (Pendred syndrome), NIS (sodium iodide symporter), and THOX2 (thyroid oxidase 2) gene defects. There is also early evidence for a third group of congenital hypothyroid conditions associated with iodothyronine transporter defects associated with severe neurological sequelae. This review focuses on the genetic aspects of primary congenital hypothyroidism. PMID:15863666

    Umbilical venous catheterization is frequently used for vascular access during neonatal resuscitation. The differentiation between umbilical artery and vein, specifically during the resuscitation procedure, is clinically neither always easy nor unambiguous. A preterm infant of 35 weeks of gestational age was born after an uneventful course of his mother's pregnancy. Severe postnatal cyanosis led to the placement of presumed arterial and venous umbilical catheters. Chest x-ray was suggestive of the presence of a persistent right umbilical vein (PRUV). Echocardiography showed a double outlet right ventricle with mitral atresia and a levo-atrial cardinal vein draining the left atrium into the azygos vein. The foramen ovale was firmly closed and conventional balloon atrioseptostomy failed. Several attempts of transseptal puncture and subsequent creation of an atrial septal defect were unsuccessful and the infant eventually died. There is an association of PRUV and congenital cardiac malformation. PRUV can be diagnosed prenatally if specifically looked for. The presence of PRUV can be the only clue prenatally alerting to the presence of congenital heart disease. Postnatal diagnosis of PRUV may justify echocardiography and cardiologic assessment even in the absence of clinical cyanosis.

    Oculodentodigital dysplasia is caused by mutations in the GJA1 gene. Oculodentodigital dysplasia presents with a spectrum of clinical features including craniofacial, ocular, dental, and limb anomalies. Although recent findings implicate the major role of GJA1 during cardiac organogenesis, congenital heart defects are infrequently reported in oculodentodigital dysplasia. Here we report on two patients with GJA1 mutations presenting with cardiac malformations and type III syndactyly. Patient 1 presented with pulmonary atresia, an intact septum, right ventricular hypoplasia and tricuspid stenosis. The infant had a small nose, thin columella and bilateral 4-5 syndactyly of the fingers. A de novo c.226C>T (p.Arg76Cys) mutation was identified. Patient 2 presented at 6 months with a ventricular septal defect. The child had hypoplastic alae nasi with a thin columella and bilateral 4-5 syndactyly of the digits. A de novo missense mutation, c.145C>G (p.Gln49Glu) was found. Our two patients underscore the importance of cardiac evaluations as part of the initial workup for patients with findings of oculodentodigital dysplasia. Conversely, those patients with type III syndactyly and congenital heart defect should be screened for GJA1 mutations.

    Bronchial artery aneurysm (BAA) is a rare vascular phenomenon. This review highlights a case of a BAA that was complicated by the presence of a bronchial artery to pulmonary artery (BA-PA) fistula, consequently presenting a unique challenge to management. BAAs have a strongly reported risk of rupture resulting in life-threatening hemoptysis. Embolization has thus become routine for the management such severe cases. The management of incidentally found anomalies is less obvious, but prophylactic embolization is a generally accepted practice. In this report, we review some of the risks and benefits associated with BAA embolization with specific consideration of the challenges in cases of co-existing BA-PA fistula. PMID:28217405

    Biliary atresia is an obstructive cholangiopathy of infancy that progresses to end-stage cirrhosis. Although the pathogenesis of the disease is not completely understood, previous reports link TNFα to apoptosis of the bile duct epithelium in the presence of IFNγ. Here, we investigate if TNFα signaling regulates pathogenic mechanisms of biliary atresia. First, we quantified the expression of TNFA and its receptors TNFR1 and TNFR2 in human livers and found an increased expression of the receptors at the time of diagnosis. In mechanistic experiments using a neonatal mouse model of rhesus rotavirus–induced (RRV-induced) biliary atresia, the expression of the ligand and both receptors increased 6- to 8-fold in hepatic DCs and NK lymphocytes above controls. The activation of tissue NK cells by RRV-primed DCs was independent of TNFα-TNFR signaling. Once activated, the expression of TNFα by NK cells induced lysis of 55% ± 2% of bile duct epithelial cells, which was completely prevented by blocking TNFα or TNFR2, but not TNFR1. More notably, antibody-mediated or genetic disruption of TNFα-TNFR2 signaling in vivo decreased apoptosis and epithelial injury; suppressed the infiltration of livers by T cells, DCs, and NK cells; prevented extrahepatic bile duct obstruction; and promoted long-term survival. These findings point to a key role for the TNFα/TNFR2 axis on pathogenesis of experimental biliary atresia and identify new therapeutic targets to suppress the disease phenotype. PMID:28289704

    Background Pulmonary atresia and intact ventricular septum is characterised by a great morphological variety. Treatment is not uniform. Objective To evaluate our experience with transcatheter valvotomy and balloon dilatation in neonates with pulmonary atresia and intact ventricular septum. Design Retrospective. Methods Between January 1997 and September 2000 five neonates with pulmonary atresia and intact ventricular septum underwent transcatheter valvotomy and balloon dilatation. Results The catheter intervention was performed at a mean age of 27 days (range 3-95 days). The atretic pulmonary valve was successfully perforated in all neonates. Subsequent balloon dilatation was successful in four neonates. Balloon dilatation was unsuccessful in one patient, who underwent an elective surgical valvotomy of the pulmonary valve after five days. Three patients needed a modified Blalock-Taussig shunt after a mean of 23 days. Four patients required repeated balloon dilatation after a mean of 227 days. Mean follow-up was 2.7 years (range 1-5 years). Conclusions Transcatheter perforation of the pulmonary valve membrane and balloon dilatation is a good, safe initial therapy in selected neonates with pulmonary atresia and intact ventricular septum. This procedure can prevent open-heart surgery in these patients in the first months of life. ImagesFigure 1Figure 2 PMID:25696158

    The mammalian ovary is an extremely dynamic organ in which a large majority of follicles are effectively eliminated throughout their reproductive life. Due to the numerous efforts of researchers, mechanisms regulating follicular growth and atresia in mammalian ovaries have been clarified, not only their systemic regulation by hormones (gonadotropins) but also their intraovarian regulation by gonadal steroids, growth factors, cytokines and intracellular proteins. Granulosa cells in particular have been demonstrated to play a major role in deciding the fate of follicles, serving molecules that are essential for follicular growth and maintenance as well as killing themselves by an apoptotic process that results in follicular atresia. In this review, we discuss the factors that govern follicular growth and atresia, with a special focus on their regulation by granulosa cells. First, ovarian folliculogenesis in adult life is outlined. Then, we explain about the regulation of follicular growth and atresia by granulosa cells, in which hormones, growth factors and cytokines, death ligand-receptor system and B cell lymphoma/leukemia 2 (BCL2) family members (mitochondria-mediated apoptosis) are further discussed.

    Introduction Thoracoscopic esophageal atresia (EA) repair was first performed in 1999, but still the technique is treated as one of the most complex pediatric surgical procedures. Aim The study presents a single-center experience and learning curve of thoracoscopic repair of esophageal atresia and tracheo-esophageal (distal) fistula. Material and methods From 2012 to 2014, 10 consecutive patients with esophageal atresia and tracheo-esophageal fistula were treated thoracoscopically in our center. There were 8 girls and 2 boys. Mean gestational age was 36.5 weeks and mean weight was 2230 g. Four children had associated anomalies. The surgery was performed after stabilization of the patient between the first and fourth day after birth. Five patients required intubation before surgery for respiratory distress. Bronchoscopy was not performed before the operation. Results In 8 patients, the endoscopic approach was successfully used thoracoscopically, while in 2 patients conversion to an open thoracotomy was necessary. In all patients except 1, the anastomosis was patent, with no evidence of leak. One patient demonstrated a leak, which did not resolve spontaneously, necessitating surgical repair. In long-term follow-up, 1 patient required esophageal dilatation of the anastomosis. All patients are on full oral feeding. Conclusions The endoscopic approach is the method of choice for the treatment of esophageal atresia in our center because of excellent visualization and precise atraumatic preparation even in neonates below a weight of 2000 g.

    Our understanding of the post-transcriptional mechanisms involved in follicular atresia is limited; however, an important development has been made in understanding the biological regulatory networks responsible for mediating follicular atresia. MicroRNAs have come to be seen as a key regulatory actor in determining cell fate in a wide range of tissues in normal and pathological processes. Profiling studies of miRNAs during follicular atresia and development have identified several putative miRNAs enriched in apoptosis signaling pathways. Subsequent in vitro and/or in vivo studies of granulosa cells have elucidated the functional role of some miRNAs along with their molecular pathways. In particular, the regulatory roles of some miRNAs have been consistently observed during studies of follicular cellular apoptosis. Continued work should gradually lead to better understanding of the role of miRNAs in this field. Ultimately, we expect this understanding will have substantial benefits for fertility management at both the in vivo or/and in vitro levels. The stable nature of miRNA holds remarkable promise in clinical use as a diagnostic tool and in reproductive medicine to solve the ever-increasing fertility problem. In this review, we summarize current knowledge of the involvement of miRNAs in follicular atresia, discuss the challenges for further work and pinpoint areas for future research. PMID:28208755

    Congenital complete heart block in utero has become diagnosed more frequently with the clinical use of fetal echocardiography. The fetus with complete heart block may remain asymptomatic or may develop congestive heart failure. Congenital complete heart block is more frequently seen in infants of mothers with systemic lupus erythematosus, both clinically manifested and subclinical systemic lupus erythematosus with positive antibodies (SS-A and SS-B antibodies). At birth, the neonate with complete heart block may remain asymptomatic and may not require a pacemaker to increase the heart rate. The indications for a pacemaker in neonates with complete heart block have been discussed. Both in-utero and neonatal management of congenital complete heart block are discussed to manage congestive heart failure in a fetus. Four patients with congenital complete heart block are presented covering a broad spectrum of clinical presentation, diagnosis, and management both in the fetal and neonatal period.

    Background: The specific recognition of oesophageal atresia (OA) with or without a tracheal fistula in a foetus is a diagnostic challenge for prenatal medicine. The aim of the present work is to analyse the value of the measurement of gastric size in the diagnosis of this significant malformation. Materials and Methods: Altogether, the examinations of 433 pregnancies between the 18.4 and 39.1 weeks of gestation were retrospectively analysed. 59 of these foetuses exhibited an OA. By means of a linear regression analysis with normal foetuses, significant parameters influencing gastric size were examined. Subsequently the gastric sizes were transformed into z values and a comparison was made between OA with and without fistulae with the help of t tests. Results: In the normal foetuses there was a significant association between the gastric circumference and the abdominal circumference (circumference = 6.809 + 0.179 × abdominal circumference, r = 0.686, p < 0.0001). In the normal group the average was 43.0 (standard deviation [SD] 13.7) mm and those in foetuses with and without fistuale were 33.8 (SD 22.7) and 0.9 (SD 3.7) mm. In 34 (57.6 %) foetuses with an OA, the gastric circumference was below the 5th percentile. In detail, there were 13 (34.2 %) foetuses with a fistula and 21 (100 %) without a fistula. The average z values in the normal group and in the groups of OA with fistula and without fistula amounted to 0.0 (SD 1.0), −1.3 (SD 2.2) and −4.5 (SD 1.0). Conclusion: Measurements of the gastric circumference below the 5th percentile should lead to further diagnostic measures, especially when associated with polyhydramnios. Although OA without a fistula is always conspicuous, only about one in three OAs with fistula are associated with a significantly smaller stomach. PMID:26719598

    Serum immunoglobulin E level was determined in 50 patients with bronchial asthma, treated in the out-patients department and clinical conditions at the Faculty Hospital--Varna. The quantitative determination of immunoglobulin E was carried out by radial immunodiffusion according to Mancini with monospecific anti-IgE globulin serum from Behringswerke (GFR). A considerable elevation of immunoglobulin E in the patients' sera was found, at an average of 394 IU (control 124 IU). A discrepancy in serum immunoglobulin E level was established with the different clinical forms of asthma. The highest are the values with infectious-allergic astmha-424 IU. High are the values both in the treated and not-treated with corticosteroids, without an essential difference between the two patient groups. Some of the rest immunoglobulins showed also an elevationppIgG 2620 mg% and IgA 366 mg%.

    Although circulating catecholamines and free serotonin in the plasma (f-5-HT) were found to be increased during asthma attacks, only f-5-HT levels correlated positively with bronchoconstriction and clinical severity. Tianeptine, a drug that enhances serotonin uptake by platelets and serotonergic axons at the central nervous system (CNS), provoked an abrupt disappearance of asthma attacks. This fact explains why tianeptine has proven to be a powerful therapeutic tool in controlling asthma. Its success has been demonstrated not only in two double-blind placebo, cross-over trials, but through an open study lasting more than seven years that included over 25,000 asthmatic patients. In the present article, we discuss the peripheral and central nervous system mechanisms that may explain the therapeutic success of tianeptine. These are summarized below. F-5-HT is taken up by pulmonary endocrine cells (PNEC) located at the parasympathetic terminals. A presynaptic element, these cells release serotonin and potentiate acetylcholine (ACh)-induced contraction of bronchial muscle. This effect is mediated by 5-HT(3) and 5-HT(4) postsynaptic receptors located at the bronchial muscle. According to the above, the increased f-5-HT plasma level, triggered by both platelet aggregation and nocturnal and/or diurnal hyperparasympathetic activity, potentiates ACh-induced bronchoconstriction. The fact that serotonin released by medullary serotonergic axons stimulates the medullary vagal cardiorespiratory neurons obliges us to think that serotonin-induced CNS mechanisms are also involved. Furthermore, the finding that drugs that interfere with serotonin uptake, by both platelets and 5-HT-terminals, worsen asthma symptoms and are able to provoke asthma attacks gives additional support to the above peripheral and CNS mechanisms.

    Bronchial epithelium is a key element of the respiratory airways. It constitutes the interface between the environment and the host. It is a physical barrier with many chemical and immunological properties. The bronchial epithelium is abnormal in asthma, even in children. It represents a key component promoting airway inflammation and remodelling that can lead to chronic symptoms. In this review, we present an overview of bronchial epithelium and how to study it, with a specific focus on children. We report physical, chemical and immunological properties from ex vivo and in vitro studies. The responses to various deleterious agents, such as viruses or allergens, may lead to persistent abnormalities orchestrated by bronchial epithelial cells. As epithelium dysfunctions occur early in asthma, reprogramming the epithelium may represent an ambitious goal to induce asthma remission in children.

    The authors discuss the efficacy of methacholine challenge to discriminate fit subjects to military service. We evaluated the relation between bronchial hyperreactivity and clinical symptoms, airways caliber and atopic status in a group of italian conscripts who reported to have bronchial asthma. Five-hundred-four subjects were studied. Bronchial hyperreactivity was measured by methacholine test, and atopic status was assessed by skin-tests. A measurable PC20 FEV1 was detected in 424 subjects. On the basis of the methacholine threshold concentration the overall sample was divided in four categories. The four categories differed as regards onset of disease, lung function and skin reactivity towards Dermatophagoides Pter, whereas no difference was found as regards skin reactivity towards Grass. In the group evaluated in spring, the four categories differed as regards skin reactivity towards Grass. In conclusion we found that bronchial hyperreactivity is related to clinical history, lung function and atopic status; the measurement of bronchial hyperreactivity is important to evaluate conscripts referring bronchial asthma.

  3. Genetics of Congenital Cataract.

    Congenital cataract is a type of cataract that presents at birth or during early childhood, and it is one of the most easily treatable causes of visual impairment and blindness during infancy, with an estimated prevalence of 1-6 cases per 10,000 live births. Approximately 50% of all congenital cataract cases may have a genetic cause, and such cases are quite heterogeneous. Although congenital nuclear cataract can be caused by multiple factors, genetic mutation remains the most common cause. All three types of Mendelian inheritance have been reported for cataract; however, autosomal dominant transmission seems to be the most frequent. The transparency and high refractive index of the lens are achieved by the precise architecture of fiber cells and homeostasis of the lens proteins in terms of their concentrations, stabilities, and supramolecular organization. Research on hereditary congenital cataract has led to the identification of several classes of candidate genes that encode proteins such crystallins, lens-specific connexins, aquaporin, cytoskeletal structural proteins, and developmental regulators. In this review, we highlight the identified genetic mutations that account for congenital nuclear cataract.

    Growing evidence has proved that many aspects of our lifestyle and the environment contribute to the development of congenital disease. Congenital spinal deformities are due to anomalous development of the vertebrae including failure of formation and segmentation during embryogenesis. The causes of congenital scoliosis have not been fully identified. A variety of factors are implicated in the development of vertebral abnormalities. Previous studies have demonstrated that both genetics and environmental factors are implicated in the development of vertebral abnormalities. However, no specific cause for congenital scoliosis has been identified. In our review, we focus on the environmental factors for the development of congenital scoliosis. Various maternal exposures during pregnancy including hypoxia, alcohol use, vitamin deficiency, valproic acid, boric acid, and hyperthermia have been observed to be associated with the occurrence of congenital scoliosis. This review describes the major environmental contributors of congenital scoliosis with an emphasis on treatment aspects associated with environmental disposition in congenital scoliosis.

    2005-09-01

    The prevalence of allergic respiratory diseases such as bronchial asthma has increased in recent years, especially in industrialized countries. A change in the genetic predisposition is an unlikely cause of the increase in allergic diseases because genetic changes in a population require several generations. Consequently, this increase may be explained by changes in environmental factors, including indoor and outdoor air pollution. Over the past two decades, there has been increasing interest in studies of air pollution and its effects on human health. Although the role played by outdoor pollutants in allergic sensitization of the airways has yet to be clarified, a body of evidence suggests that urbanization, with its high levels of vehicle emissions, and a westernized lifestyle are linked to the rising frequency of respiratory allergic diseases observed in most industrialized countries, and there is considerable evidence that asthmatic persons are at increased risk of developing asthma exacerbations with exposure to ozone, nitrogen dioxide, sulphur dioxide and inhalable particulate matter. However, it is not easy to evaluate the impact of air pollution on the timing of asthma exacerbations and on the prevalence of asthma in general. As concentrations of airborne allergens and air pollutants are frequently increased contemporaneously, an enhanced IgE-mediated response to aeroallergens and enhanced airway inflammation could account for the increasing frequency of allergic respiratory allergy and bronchial asthma. Pollinosis is frequently used to study the interrelationship between air pollution and respiratory allergy. Climatic factors (temperature, wind speed, humidity, thunderstorms, etc) can affect both components (biological and chemical) of this interaction. By attaching to the surface of pollen grains and of plant-derived particles of paucimicronic size, pollutants could modify not only the morphology of these antigen-carrying agents but also their allergenic

    An early stage of Leber's congenital amaurosis, characterized by white spots or lines in the fundus, occurred in two children. Light microscopic examination of eyes obtained from one child, a 16-month-old Japanese girl, revealed subretinal deposits corresponding to the white spots and lines in the fundus deposits. Light and electron microscopic examination of the eye showed distinctive changes in the outer retinal layers and choroid, while the inner retinal layers were nearly normal. Characteristic early lesions of congenital amaurosis appeared to be produced by deposits consisting of loose outer segments and apical processes of the pigmental epithelial cell and macrophages. Undifferentiation in the nuclei of the photoreceptor cell, the inner segment, the pigment epithelial cell, and the choriocapillaris were likely characteristics of the early changes of congenital amaurosis.

    Leber's congenital amaurosis is an autosomal recessive disorder, characterized by the onset of blindness before the age of 6 months, a variable fundus aspect and an absent or extremely pathological ERG. The disorder may be isolated or associated with systemic involvement, such as nephronophtisis (Senior-Loken syndrome), nephronophtisis, cone-shaped epiphyses of the hand and cerebellar ataxia (Saldino-Mainzer syndrome), vermis hypoplasia, oculomotor anomalies and respiratory problems in the neonatal period (Joubert syndrome) or cardiomyopathy. It should be differentiated from other forms or chorioretinal dystrophies (juvenile retinitis pigmentosa or congenital stationary night blindness), cortical blindness or maturation delay and metabolic disorders. Children with possible congenital Leber amaurosis should not only have a thorough ophthalmological examination, but should also be seen by a paediatrician experienced in metabolic disorders.

    Bronchial artery aneurysm is uncommon, and the occurrence of multiple aneurysms arising from a bronchial artery is even rarer. To date, there has been only one published case report describing double bronchial artery aneurysms. We herein describe a case of three aneurysms arising from a left bronchial artery, accompanied by multiple bilateral hypertrophied bronchial and intercostobronchial arteries, as well as a double aortic arch. Bronchial artery aneurysm is potentially life-threatening, and immediate treatment is recommended to minimise the potential risk of rupture. The aneurysms in our case were successfully treated via transcatheter arterial embolisation using coils. PMID:25820859

    Red blood cell (RBC) destruction can be secondary to intrinsic disorders of the RBC or to extrinsic causes. In the congenital hemolytic anemias, intrinsic RBC enzyme, RBC membrane, and hemoglobin disorders result in hemolysis. The typical clinical presentation is a patient with pallor, anemia, jaundice, and often splenomegaly. The laboratory features include anemia, hyperbilirubinemia, and reticulocytosis. For some congenital hemolytic anemias, splenectomy is curative. However, in other diseases, avoidance of drugs and toxins is the best therapy. Supportive care with transfusions are also mainstays of therapy. Chronic hemolysis often results in the formation of gallstones, and cholecystectomy is often indicated.

    Pediatric congenital intracranial infections are a group of different and important entities that constitute a small percentage of all pediatric infections. The causal factors and clinical presentations are different in children compared with adults. They require early recognition because delay diagnosis and initiation of treatment may have catastrophic consequences. Despite improvements in prenatal screening, vaccine safety, and antibiotics, infections of the central nervous system remain an important cause of neurological disabilities worldwide. This article reviews the most common congenital infections and their imaging findings.

    Acute infection of toxoplasmosis during pregnancy is detrimental to the developing fetus. In the United States, approximately 1 in 10,000 live births are affected by congenital toxoplasmosis. Although multifactorial in etiology, maternal infection is primarily attributed to the consumption of contaminated meat or water. Infection and transmission to the fetus may result in devastating neurologic impairment. Screening methods for all pregnant women should be implemented in routine prenatal care. This article will highlight the inherent dangers of congenital toxoplasmosis, while including general care of the fetus for prevention of transmission, medical management, and long-term outcomes.

  16. [Effects of high altitude on bronchial asthma].

    2008-03-01

    Sojourns in the high mountains have been recommended to patients with asthma for many decades. It is the aim of this contribution to summarise the published studies about the effects of a stay at > 1500 m above sea level on asthmatic patients. These data from 428 adolescent and adult patients indicate an improvement of asthma symptoms and lung function during sojourns at high altitude. In many patients a reduction of the steroid therapy was achievable. Profound changes in the immune system have been demonstrated at high altitude, with a reduction of B- and T-helper cell activation. Total and mite-specific immunoglobulin E antibodies decrease significantly during longer sojourns. These changes are associated with a reduction of airway inflammation (e. g., reduction of eosinophil activation, NO exhalation and bronchial hyper-responsiveness). The fact that also patients with non-allergic asthma demonstrate a reduction of their airway inflammation at high altitude suggests that the high altitude climate has beneficial effects on asthma beyond the effects of allergen avoidance. High UV exposure and low humidity could be important additional factors, to explain the reductions in asthma severity in the high mountain climate. Larger controlled studies should be performed to prove the positive effects of the high altitude climate on asthma.

    From the paediatric point of view, we have undertaken two Delphi studies into bronchial asthma. The first is related to the consensus known as the consensus document of the five associations. The second is more recent and has been undertaken with GEMA (the Spanish Guidelines on the Management of Asthma). The aim of this paper is to carry out a descriptive study comparing the 2 Delphi processes and to objectively assess if in some way behaviour over the past two years has changed as far as expert opinion is concerned. In the consensus document those points giving rise to most controversy were the treatment of children under three years of age and treatment with immunotherapy in allergic asthma. It is also necessary to highlight how important it was at that particular point in time to define the phenotypes of wheezing and the predictive index of asthma in children of less than 3 years of age. Of the 52 questions in the questionnaire, in 13.6% the panel of experts reached no consensus in their positions. Following GEMA the Delphi methodology, 56 questions were asked in the first round of the questionnaire, and consensus was reached in 87.5%. As regards the paediatric part relating to diagnosis and treatment in children, agreement was reached on all the questions in the first round. Agreement was reached in 8.92% questions in the second round. Clinical guidelines and consensus documents can modify behaviour towards an illness, both in the diagnosis and treatment.

    1. Needle acupuncture was performed at three sites in twenty patients in a clinical attack of bronchial asthma. 2. In all patients the symptoms of bronchoconstriction improved during the attacks when the correct site was stimulated, and in five patients wheezing was abolished. 3. Stimulation at the correct site produced a significant increase in the mean FEV1-0 (58%) and FVC (29%) but not in maximal mid-expiratory flow rate (MMFR; 76%), when compared with the findings before acupuncture, along with a significant fall in the Pa,CO2 and an insignificant fall in Pa,O2. A mild tachycardia was also observed. 4. After acupuncture a greater improvement in FEV1-0, FVC and MMFR was produced by inhalation of isoprenaline. 5. No significant changes in FEV1-0, FVC, MMFR, pulse rate or arterial blood gas tensions occurred after acupuncture at control sites. 6. In four of the patients during clinical remission acupuncture was performed before and after histamine aerosol challenge, but there was no effect on either the severity or the duration of the histamine-induced bronchoconstriction. 7. It is concluded that acupunture probably reduced the reflex component of the bronchoconstriction, but failed to influence direct smooth muscle constriction caused by histamine.

    Survival rates in oesophageal atresia patients have reached over 90%. In long-term follow-up studies the focus has shifted from purely surgical or gastrointestinal evaluation to a multidisciplinary approach. We reviewed the literature on the long-term morbidity of these patients and discuss mainly issues of physical growth and neurodevelopment. We conclude that growth problems - both stunting and wasting - are frequently seen, but that sufficient longitudinal data are lacking. Therefore, it is unclear whether catch-up growth into adolescence and adulthood occurs. Data on determinants of growth retardation are also lacking in current literature. Studies on neurodevelopment beyond preschool age are scarce but oesophageal atresia patients seem at risk for academic problems and motor function delay. Many factors contribute to the susceptibility to growth and development problems and we propose a multidisciplinary follow-up schedule into adulthood future care which may help improve quality of life.

    A 3 yr old male castrated Labrador retriever presented for evaluation and treatment of bilateral atresia of the external ear canals. The owners reported that the dog could hear only loud and high-pitched noises. Computed tomography of the head revealed intact vertical and horizontal ear canals filled with debris and a debris-filled right tympanic bulla. Air- and bone-conducted brainstem auditory evoked response (BAER) testing revealed an elevated response threshold to air-conducted stimuli and greater amplitude waveforms evoked by bone-conducted stimuli. The ear canals were surgically corrected via lateral ear canal resection. BAER testing postoperatively revealed a decrease in the air-conducted BAER threshold. This case is an example of the use of bone-conducted BAER testing to aid in the diagnosis of conductive deafness, and in determining prognosis for normal hearing after surgical treatment of external ear canal atresia.

    Matrix metalloproteinases (MMPs) are the proteases responsible for tissue remodeling during liver fibrosis caused by various disorders including biliary atresia. However, information regarding the relative contribution of these proteases to liver fibrosis is still limited. We studied matrix metalloproteinase-2 (MMP-2), -7, -9 and -13 mRNA expressions in the liver tissue of early-stage biliary atresia at the time of Kasai's procedure, late-stage biliary atresia at the time of liver transplantation with advanced fibrosis and nondiseased control without liver fibrosis. The results of real-time quantitative reverse transcriptase-PCR analysis revealed that only MMP-2 and -7 expressions were significantly different between groups. MMP-2 was significantly higher in Liver Transplantation group than both in Control (P=0.010) and in Kasai's Procedure (P=0.001) groups, whereas the difference of MMP-2 expression between Control and Kasai's Procedure was not significant. However, the relative expression level of MMP-7 was sequentially elevated when comparing Control, Kasai's Procedure and Liver Transplantation groups, and there was significant (P=0.019) difference when comparing Control and Liver Transplantation groups. Moreover, the fold difference in MMP-7 mRNA was much higher than that in MMP-2 mRNA between groups. The expressions of MMP-7 were further confirmed by agarose gel electrophoresis and Western blotting. Immunohistochemical analysis revealed a significant positive correlation of the scores of MMP-7 immunostaining with the stages of liver fibrosis. In situ hybridization demonstrated that the bile ductular epithelial cells, Kupffer cells and hepatocytes were the major producers of matrix metalloproteinase-7 in the liver. Our results imply that MMP-7 is a major MMP associated with the tissue remodeling during the progression of liver fibrosis in biliary atresia.

    Surgical correction of patients with tetralogy of Fallot with pulmonary atresia is now one of the routine procedures performed by pediatric cardiac surgeons. In one variant, the pulmonary arterial supply is derived from a fistulous communication from the coronary arteries. This rare and interesting situation poses a diagnostic and therapeutic dilemma, as well as providing specific management challenges to the surgical team. Here, we discuss important aspects of this rare variant, specifically its morphology, presentation, evaluation and management.

    1998-09-01

    The germinal disc region (GDR), which contains the germinal disc and overlying granulosa cells, is essential for completion of maturation of the preovulatory chicken follicle. The current study was conducted to test the hypothesis that destruction of the GDR (GDRX) of an immature preovulatory chicken follicle blocks ovulation, induces apoptosis, and causes atresia. The GDR of immature preovulatory follicles (F2) were destroyed by freezing with dry ice (3 mm in diameter) 48-50 h before ovulation. As a control for the effect of freezing, a nonGDR portion (a portion of the follicular wall opposite to the GDR relative to the follicular stalk) of other F2 follicles were destroyed (nonGDRX). Treatment of F2 follicles by GDRX caused atresia and blocked ovulation of all treated follicles (6 of 6), whereas none of the nonGDRX follicles (0 of 5) underwent atresia. Treatment of follicles by GDRX induced apoptotic DNA fragmentation (laddering) in theca and granulosa layers obtained from the frozen area and in the theca layer obtained from the follicular wall distal to the frozen area. In contrast, apoptosis was only present in theca and granulosa layers in the frozen area of the nonGDRX follicle. Furthermore, the in situ DNA end-labeling technique demonstrated that in the GDRX follicle 24 h after treatment, cells in the theca interna, endothelial cells in blood vessels of the theca externa, and a few granulosa cells underwent apoptosis. These results indicate that destruction of the GDR of an immature preovulatory follicle causes atresia and apoptosis and blocks ovulation. These novel findings suggest that the GDR maintains development of the chicken preovulatory follicle by producing one or more survival factors. Without the GDR, chicken follicles cannot develop further and they eventually die.

  6. Equol inhibits growth, induces atresia, and inhibits steroidogenesis of mouse antral follicles in vitro

    Equol is a non-steroidal estrogen metabolite produced by microbial conversion of daidzein, a major soy isoflavone, in the gut of some humans and many animal species. Isoflavones and their metabolites can affect endogenous estradiol production, action, and metabolism, potentially influencing ovarian follicle function. However, no studies have examined the effects of equol on intact ovarian antral follicles, which are responsible for sex steroid synthesis and further development into ovulatory follicles. Thus, the present study tested the hypothesis that equol inhibits antral follicle growth, increases follicle atresia, and inhibits steroidogenesis in the adult mouse ovary. To test this hypothesis, antral follicles isolated from adult CD-1 mice were cultured with vehicle control (dimethyl sulfoxide; DMSO) or equol (600 nM, 6 μM, 36 μM, 100 μM) for 48 and 96 h. Every 24 h, follicle diameters were measured to monitor growth. At 48 and 96 h, the culture medium was subjected to measurement of hormone levels, and the cultured follicles were subjected to gene expression analysis. Additionally, follicles were histologically evaluated for signs of atresia after 96 h of culture. The results indicate that equol (100 μM) inhibited follicle growth, altered the mRNA levels of bcl2-associated X protein and B cell leukemia/lymphoma 2, and induced follicle atresia. Further, equol decreased the levels of estradiol, testosterone, androstenedione, and progesterone, and it decreased mRNA levels of cholesterol side-chain cleavage, steroid 17-α-hydroxalase, and aromatase. Collectively, these data indicate that equol inhibits growth, increases atresia, and inhibits steroidogenesis of cultured mouse antral follicles. PMID:26876617

    Single center experience with thoracoscopic repair of esophageal atresia with distal fistula and of tracheomalacia. Between May 2000 and December 2006, 51 neonates with an esophageal atresia were presented for thoracoscopic repair. Gestational age varied from 31 3/7 to 42 2/7 weeks (M = 37 2/7). Birth weight was between 1025 g and 4030 g (mean 2620 g). Concomitant anomalies or VACTERL association were encoutered in 31 patients (61%). Duration of the operation was from 90 minutes to 390 minutes (mean 178 minutes). All but 1 patient had an esophageal atresia with a distal fistula. Six patients had tracheomalacia requiring aortopexia, which was performed thoracoscopically. In 2 patients the thoracoscopic procedure had to be converted to a thoracotomy. All other patients underwent a successful thoracoscopic repair. One patient died in the postoperative period because of sepsis. A total of 22 patients (45%) developed a stenosis in the postoperative follow up (1 month-7y 7 month) requiring 1 to 18 dilatations (mean 1.5). Postoperative leakage occurred in 9 patients (18%). Recurrent fistula was encountered in 2 patients. A total of 11 patients (22%) underwent a laparoscopic antireflux procedure for either recurring stenosis (8) or ALTES (3). Six children (12%) underwent thoracoscopic aortopexy for tracheomalacia. In 2 children symptoms recurred for which a successful repeat thoracoscopic aortopexy was undertaken. The thoracoscopic approach to the treatment of esophageal atresia and tracheomalacia is becoming increasingly accepted. The cosmesis is undoubtedly better. The secundary effects like thoracic cage deformities, winged scapula, or scoliosis have not yet been described and are expected to be reduced in comparison to the open technique. Sequelae like leakage, stenosis, recurrent fistulae, and GERD and ALTES will probably remain the same. Whether thoracoscopic dissection has less detrimental effect on disturbed motility remains to be proven. Thoracoscopic aortopexy

    Out of 19 patients with extrinsic bronchial asthma challenged with 123 mug histamine acid phosphate by intravenous infusion only 13 responded with a fall in FEV1 of over 10% (mean 16%). Seventeen of these patients were given histamine 2 mg/ml by aerosol, and all responded with a mean decrease in FEV1 of 37.8%. When challenged with allergen extract by aerosol the mean decrease in FEV1 was 37.5%. After 40 mg sodium cromoglycate 15 of the 17 patients showed significant protection against allergen challenge with a mean decrease in FEV1 of only 23.6%. Inhalation of 40 mg sodium cromoglycate, however, failed to protect against histamine given by either the intravenous or aerosol route. Histamine given intravenously to asthmatic patients produces less of a bronchial response than when given by aerosol, even though the intravenous route produces many more systemic symptoms, such as flushing and throbbing headache. The protection of sodium cromoglycate against an allergen inhalation challenge is not due to histamine antagonsim. PMID:816411

    Background. Patients with unilateral atresia and microtia encounter problems in sound localization and speech understanding in noise. Although there are four implantable hearing devices available, there is little discussion and evidence on the application of these devices on patients with unilateral atresia and microtia problems. Objective. This paper will review the details of these four implantable hearing devices for the treatment of unilateral atresia. They are percuteaneous osseointegrated bone anchored hearing aid, Vibrant Soundbridge middle ear implant, Bonebridge bone conduction system, and Carina fully implantable hearing device. Methods. Four implantable hearing devices were reviewed and compared. The clinical decision process that led to the recommendation of a device was illustrated by using a case study. Conclusions. The selection of appropriate implantable hearing devices should be based on various factors, including radiological findings and patient preferences, possible surgical complications, whether the device is Food and Drug Administration- (FDA-)/CE-approved, and the finances. To ensure the accurate evaluation of candidacy and outcomes, the evaluation methods should be adapted to suite the type of hearing device. PMID:24991564

  10. Staging of biliary atresia at diagnosis by molecular profiling of the liver

    2010-01-01

    Background Young age at portoenterostomy has been linked to improved outcome in biliary atresia, but pre-existing biological factors may influence the rate of disease progression. In this study, we aimed to determine whether molecular profiling of the liver identifies stages of disease at diagnosis. Methods We examined liver biopsies from 47 infants with biliary atresia enrolled in a prospective observational study. Biopsies were scored for inflammation and fibrosis, used for gene expression profiles, and tested for association with indicators of disease severity, response to surgery, and survival at 2 years. Results Fourteen of 47 livers displayed predominant histological features of inflammation (N = 9) or fibrosis (N = 5), with the remainder showing similar levels of both simultaneously. By differential profiling of gene expression, the 14 livers had a unique molecular signature containing 150 gene probes. Applying prediction analysis models, the probes classified 29 of the remaining 33 livers into inflammation or fibrosis. Molecular classification into the two groups was validated by the findings of increased hepatic population of lymphocyte subsets or tissue accumulation of matrix substrates. The groups had no association with traditional markers of liver injury or function, response to surgery, or complications of cirrhosis. However, infants with an inflammation signature were younger, while those with a fibrosis signature had decreased transplant-free survival. Conclusions Molecular profiling at diagnosis of biliary atresia uncovers a signature of inflammation or fibrosis in most livers. This signature may relate to staging of disease at diagnosis and has implications to clinical outcomes. PMID:20465800

    Background In this study, we investigated the effect of hyperbaric oxygen therapy (HBOT) on the morphology of estradiol valerate (EV) induced polycystic ovary (PCO) to find a new treatment modality for improvement of PCO. Methods The rats were divided into four groups. Group1, control; group 2, PCO group; group 3, PCO with HBOT group and group 4, normal ovary with HBOT. PCO was induced by a single intramuscular injection of 4 mg EV in adult cycling rats. Other rats with normal ovaries had oil injection as placebo. HBOT was applied to third and fourth groups for six weeks. Histopathologic evaluation of ovaries of all groups were performed & compared. Results Six weeks of HBOT was resulted in increase in follicular atresia, decrease in the number of primary, secondary, tertiary follicles and decrease in the number of fresh corpus luteum in normal rat ovary. HBOT on polycystic rat ovary, resulted in significant increase in atretic follicles which were already present. Conclusions HBOT of six weeks itself, changed ovarian morphology in favor of atresia both in PCO group and control group. This result of aggravated follicular atresia after HBOT on EV induced PCO may be due to long-term exposure in our protocol which with this state seems to be inapplicable in the improvement of PCO morphology.

    OBJECTIVE--To assess the possibility of maintaining ductal patency in neonates with complex pulmonary atresia by percutaneous implantation of balloon expandable stents. PATIENTS--Two duct-dependent neonates with long segment pulmonary atresia, right sided aortic arch, and left sided arterial duct. RESULTS--Stents with final diameter of 3.5 or 4 mm and initial length of 7 or 15 mm were successfully positioned in the arterial duct. Two stents were required in one child and four in the other in order to stent the entire length of the duct. After the procedures the ducts remained widely patent and arterial oxygen saturations remained above 80%. Complications of the procedures included perforation of a peripheral pulmonary artery and cardiac perforation, both caused by guide wire manipulation. Both babies died suddenly, one at five weeks, and the other at nine days after successful stenting of the duct. Both ducts were patent at necropsy; the exact cause of one death was not clearly defined, but the second seemed to be caused by pneumococcal septicaemia. CONCLUSIONS--Stenting of the arterial duct is technically feasible. It provides adequate palliation for neonates with pulmonary atresia at least in the short term and it seems to result in balanced, central perfusion of both pulmonary arteries. This preliminary report suggests that this previously untried technique may prove to be a promising and attractive alternative to neonatal aortopulmonary shunt operation. Images PMID:1372815

  13. Etiologic factors in long-term respiratory function abnormalities following esophageal atresia repair.

    Recurrent respiratory illnesses are frequent in infants following repair of esophageal atresia and functional abnormalities of respiratory and esophageal function are often seen in older children. Recurrent aspiration is a potential cause of these respiratory abnormalities, but a relationship between abnormalities of gastrointestinal and respiratory mechanics has not been adequately investigated. We sought an association between lower esophageal sphincter (LES) incompetence, gastroesophageal reflux (GER), and respiratory function abnormalities in 18 subjects (age 12 to 21 years) following repair of esophageal atresia (Vogt type 111B). In each subject, measurements were made of spirometry, lung volumes assessed by plethysmography, esophageal manometry recorded using a constantly infused fluid-filled trilumen catheter to assess LES pressure and esophageal motility, and esophageal pH monitoring to detect GER. Subjects were grouped according to the presence or absence of a radiologically supported diagnosis of pneumonia in the first 4 years of life. Lung volumes were mildly but significantly decreased in the "pneumonia" group compared with the "nonpneumonia" group. There was no association between abnormalities of respiratory function and abnormal LES pressure or the presence of GER. These data suggest that pneumonia in esophageal atresia infants is associated with mild long-term lung damage. LES dysfunction and GER do not appear to play a major role in this process.

    Lipoprotein-X (LP-X) in cholestatic jaundice causes abnormal reaction in assays for low-density lipoprotein-cholesterol, but the effects on other test items are unknown. Here, we report an infant with biliary atresia showing abnormal reaction in total serum protein assay using the biuret method, and lipoprotein-X (LP-X) was then detected. In this 11-month-old female infant, jaundice was observed at 2 months old, and a diagnosis of biliary atresia was made. On biochemical tests at 12 months old, the total serum protein concentrations detected by the biuret method were very high, and the response curve and linearity of dilution were abnormal. LP-X was detected by agar electrophoresis. In addition and recovery experiments with normal serum fractionation of the patient's LP-X-rich lipoprotein fraction prepared by ultracentrifugation, normal γ-globulin fractionation showed an abnormal reaction by the biuret method. In infants with biliary atresia, we showed that the total serum protein assay by the biuret method was influenced by LP-X-rich lipoprotein, which may be caused by abnormal reaction of LP-X and γ-globulin.

    Our objective was to evaluate the usefulness of embolizing collateral vessels using mechanically detachable coils (MDCs) in children aged 3 years or younger with congenital heart disease. The subjects were 8 children with congenital heart disease featuring collateral vessels (age 18 days-3 years): 3 with a single ventricle, 2 with the tetralogy of Fallot, 2 with pulmonary atresia, and 1 with a ventricular septal defect. The embolized vessels were the major aortopulmonary collateral artery (MAPCA) in 5 patients, the persistent left superior vena cava in 2, and the coronary arteriovenous fistula in 1. A 4 or a 5 F catheter was used as the guiding device, and embolization was performed using MDCs and other conventional coils introduced through the microcatheter. One patient had growth of new MAPCAs after embolization, and these MAPCAs were also embolized with MDCs. Thus, a total of 9 embolization procedures were performed in 8 patients. Complete occlusion of the collateral vessels was achieved in 8 of 9 procedures (89%). Seven of 8 patients (88%) had uneventful courses after embolization, and MDC procedures appeared to play important roles in avoiding coil migration and achievement of safe coil embolization. One patient who underwent MAPCA embolization showed no improvement in heart function and died 2 months and 19 days later. Embolization of collateral vessels using MDCs in young children with congenital heart disease can be an effective procedure and a valuable adjunct to surgical management.

  18. Anesthesia for the adult patient with an unrepaired congenital cyanotic heart defect: a case report.

    2012-06-01

    Adult congenital heart disease, previously considered a rare comorbidity, is increasingly becoming a reality for today's anesthesia providers. Improvements in prenatal diagnosis, sophisticated surgical techniques and equipment, advances in pediatric critical care, enhanced efficacy of cardiovascular pharmacologic agents, and an overall increase in postrepair survival rates have resulted in an estimated population of approximately 800,000 adults with congenital heart disease. Despite successful surgical repair or palliation, these individuals present the anesthesia provider with a multitude of challenges. Individualized care of these fragile patients should be approached with a keen understanding of the patient's underlying cardiac anomaly. This case report chronicles the anesthetic care of a 36-year-old woman presenting for left-sided ureteroscopy with laser lithotripsy and stent placement. Her medical history was remarkable for the presence of complex congenital heart disease consisting of multiple anomalies: a double-outlet right ventricle, transposition of the great arteries, pulmonary stenosis, atrial septal defect, and a hypoplastic left ventricle with concomitant mitral valve atresia. General anesthesia was successfully administered, with meticulous attention given to maintenance of systemic vascular resistance to minimize shunting, oxygenation, administration of preprocedure antibiotics, and judicious replacement of intravenous fluids via air-filtered tubing.

    Genetic variation in specific transcription factors during heart formation may lead to congenital heart disease (CHD) or even miscarriage. The aim of the present study was to identify CHD‑associated genes using next generation sequencing (NGS). The whole exome DNA sequence was obtained from a stillborn fetus diagnosed with tricuspid atresia and complete transposition of the great arteries using high‑throughput sequencing methods. Subsequently, genetic variants of CHD‑associated genes were selected and verified in 215 non‑syndromic CHD patients and 249 healthy control subjects using polymerase chain reaction combined with Sanger sequencing. Genetic variants of previously reported CHD‑inducing genes, such as cysteine rich with EGF like domains 1 and cbp/p300‑interacting transactivator with Glu/Asp rich carboxy‑terminal domain 2, were discovered through the NGS analysis. In addition, a novel non‑synonymous mutation of the iroquois homeobox 1 (IRX1) gene (p.Gln240Glu) was identified. A total of three non‑synonymous mutations (p.Gln240Glu, p.Ser298Asn and p.Ala381Glu) of the IRX1 gene were verified in 215 non‑syndromic CHD patients, but not in 249 healthy volunteers. The results demonstrated that NGS is a powerful tool to study the etiology of CHD. In addition, the results suggest that genetic variants of the IRX1 gene may contribute to the pathogenesis of CHD.

  5. Persistent specific bronchial reactivity to occupational agents in workers with normal nonspecific bronchial reactivity.

    PubMed

    2000-09-01

    Specific bronchial reactivity (SBR) to common inhalants is related to the degree of nonspecific bronchial reactivity (NSBR) and to specific allergen sensitivity. We investigated 16 workers with normal NSBR who had been previously diagnosed with occupational asthma caused by high-molecular-weight agents. The agents were flour in seven workers, psyllium in five, and guar gum in four. The subjects had been removed from exposure to these agents for a mean of 5.7 (+/- 4.0 SD) yr, no longer showed evidence of persisting asthma, and had a normal lung function. In the present study, the workers were reexposed to the sensitizing agent by specific inhalation challenges, in the same way they were as at the time of the diagnosis, to assess their current SBR to the sensitizer. SBR was estimated as the duration of exposure that induced a 20% decrease in FEV(1). Eleven of the 16 subjects had an asthmatic reaction at the time of the study; the duration of exposure necessary to induce the asthmatic reaction was the same as that needed at the time of diagnosis (3.55 +/- 0.5 min and 4.2 +/- 0.7 min, respectively, p = 0.8). The decrease in specific IgE levels between the two events was much greater in the subjects who failed to react to the second challenge test (from 24.2 +/- 37.5% to 3.0 +/- 16.9% binding) than in those who reacted on both occasions (from 31.2 +/- 27.0% to 21.6 +/- 36.7% binding); however, in both groups the change was significant (p = 0.05 and 0.04, respectively). We conclude that SBR to high-molecular-weight agents persists in most cases despite a normalization of NSBR, and that this persistence is associated with a persistence of specific immunization to the agent.

    Congenital omental cysts are rare intra-abdominal pathology, which are difficult to diagnose preoperatively; as such a high index of suspicion is required for accurate preoperative diagnosis. We present a case of congenital omental cyst in a 3-year-old girl who presented with huge abdominal distension. We performed diagnostic examinations including ultrasonography and CT of the abdomen. An omental cyst was diagnosed because of its position and connection to the surrounding tissues. She was operated and cyst was excised completely. Histological examination revealed an omental cyst with endothelial lining and haemorrhagic fluid inside. She had an uneventful recovery and doing well, without recurrence at follow-up of 24 months. Clinicians must rigorously pursue a preoperative diagnosis, as it may prevent a surprise upon laparotomy and result in proper management. PMID:22865812

A 3-day-old male, born at 39 weeks’ gestation without relevant prenatal history, presented with a large vascularized proptotic mass distorting the left midface. Laboratory studies showed elevated serum alpha-fetoprotein (12,910 ng/ml). Computed tomography showed a multiloculated heterogeneous lesion composed of hypodense and hyperdense calcified areas encompassing the whole orbital cavity with expansion of the bony walls, as well as forward displacement and compression of the eyeball without extension to surrounding structures. Clinical, imaging and laboratory features were consistent with congenital orbital teratoma. Due to pronounced proptosis with exposure keratopathy and corneal perforation, no motility of the globe and no vision in the affected eye in a resource-limited setting, the patient underwent orbital exenteration. Histopathological examination confirmed the diagnosis of mature cystic teratoma. We describe the clinical course, radiographic and histopathological findings of this rare orbital tumor.

    Introduction Outcome studies of tracheoesophageal fistula (TEF) and/or esophageal atresia (EA) are limited to retrospective chart reviews. This study surveyed TEF/EA patients/parents engaged in social media communities to determine long-term outcomes. Materials and Methods A 50-point survey was designed to study presentation, interventions, and ongoing symptoms after repair in patients with TEF/EA. It was validated using a test population and made available on TEF/EA online communities. Results In this study, 445 subjects completed the survey during a 2-month period. Mean age of patients when surveyed was 8.7 years (0-61 years) and 56% were male. Eighty-nine percent of surveys were completed by the parent of the patient. Sixty-two percent of patients underwent repair in the first 7 days of life. Standard open repair was most common (56%), followed by primary esophageal replacement (13%) and thoracoscopic repair (13%). Out of 405, 106 (26%) patients had postoperative leak. Postoperative leak was least likely in primary esophageal replacement (18%) and standard open repair (19%). Leak occurred in 32% of patients who had thoracoscopic repair; 31% (128/413) reported long-gap atresia, which was significantly associated with increased risk of postoperative leak (54/128, 42%) when compared with standard short-gap atresia (odds ratio, 3.5; p = 0.001). Out of 409, 221 (54%) patients reported dysphagia after repair, with only 77/221 (34.8%) reporting resolution by age 5. Out of 381, 290 (76%) patients reported symptoms of gastroesophageal reflux disease (GERD). There was no difference in dysphagia rates or GERD symptoms based on type of initial repair. Antireflux surgery was required in 63/290, 22% of patients with GERD (15% of all patients) and 27% of these patients who had surgery required more than one procedure antireflux procedure. The most common was Nissen fundoplication (73%), followed by partial wrap (14%). Reflux recurred in 32% of patients after

    Ptosis is defined as an abnormally low position of the upper eyelid margin. It can be congenital or acquired, uni or bilateral, and isolated or associated with other ocular and nonocular defects. We report a case of a female child, aged 8 years, with congenital right ptosis increased on right adduction and with left ptosis on left adduction. There was no horizontal ocular movement limitation. Apparent underaction of the right inferior oblique muscle was also present. We believe that within the possible mechanisms it is more likely that it is a congenital innervation dysgenesis syndrome (CID)/congenital cranial dysinnervation disorder (CCDD).

    Leber's congenital amaurosis (LCA) is the earliest and most severe form of all inherited retinal dystrophies responsible for congenital blindness. Genetic heterogeneity of LCA has been suspected since the report by Waardenburg of normal children born to affected parents. In 1995, we localized the first disease causing gene, LCA1, to chromosome 17p13 and confirmed the genetic heterogeneity. In 1996, we ascribed LCA1 to mutations in the photoreceptor-specific guanylate cyclase gene (retGC1). RetGC1 is an essential protein implicated in the phototransduction cascade, especially in the recovery of the dark state after the excitation process of photoreceptor cells by light stimulation. In 1997, mutations in a second gene were reported in LCA, the RPE65 gene, which is the first specific retinal pigment epithelium gene. The protein RPE65 is implicated in the metabolism of vitamin A, the precursor of the photoexcitable retinal pigment (rhodopsin). Finally, a third gene, CRX, implicated in photoreceptor development, has been suspected of causing a few cases of LCA. Taken together, these three genes account for only 27% of LCA cases in our series. The three genes encode proteins that are involved in completely different physiopathologic pathways. Based on these striking differences of physiopathologic processes, we reexamined all clinical physiopathological discrepancies and the results strongly suggested that retGC1 gene mutations are responsible for congenital stationary severe cone-rod dystrophy, while RPE65 gene mutations are responsible for congenital severe but progressive rod-cone dystrophy. It is of tremendous importance to confirm and to refine these genotype-phenotype correlations on a large scale in order to anticipate the final outcome in a blind infant, on the one hand, and to further guide genetic studies in older patients on the other hand.

    Congenital hearing loss (hearing loss that is present at birth) is one of the most prevalent chronic conditions in children. In the majority of developed countries, neonatal hearing screening programmes enable early detection; early intervention will prevent delays in speech and language development and has long-lasting beneficial effects on social and emotional development and quality of life. A diagnosis of hearing loss is usually followed by a search for an underlying aetiology. Congenital hearing loss might be attributed to environmental and prenatal factors, which prevail in low-income settings; congenital infections, particularly cytomegalovirus infection, are also a common risk factor for hearing loss. Genetic causes probably account for the majority of cases in developed countries; mutations can affect any component of the hearing pathway, in particular, inner ear homeostasis (endolymph production and maintenance) and mechano-electrical transduction (the conversion of a mechanical stimulus into electrochemical activity). Once the underlying cause of hearing loss is established, it might direct therapeutic decision making and guide prevention and (genetic) counselling. Management options include specific antimicrobial therapies, surgical treatment of craniofacial abnormalities and implantable or non-implantable hearing devices. An improved understanding of the pathophysiology and molecular mechanisms that underlie hearing loss and increased awareness of recent advances in genetic testing will promote the development of new treatment and screening strategies.

The authors have described three children with congenital insensitivity to pain. The disease was diagnosed at the age of 3-5. These children painlessly have broken their lower limbs. These fractures were late diagnosed what resulted in a badly healed deformation of legs. For this reason, the right knee of the oldest boy had to be stiffened. This boy had also late diagnosed the left hip luxation, and hematomas had arisen, which become filled with pus. The boy was in sepsis and a dramatic life-and-death struggle was performed. A purulent focuses were removed from abdomen and femoral head was also resected. The other two siblings had fractures and infections, but not such severe as the oldest boy. It is well known that a causal treatment of this disease in unknown. Patients must learn to avoid mechanical and thermal trauma. It is the only way to prevent complications of this disease.

    Congenital knee dislocation is an infrequent condition with unknown etiology. In some cases it occurs as an isolated condition, while in others it coexists with associated conditions or syndromes. The treatment of congenital knee dislocation is driven by the severity and flexibility of the deformity. The literature includes from serial casting or the Pavlik harness to quadriceps tendon plasty or femoral osteotomies. We report herein the case of a congenital dislocation treated with serial casting with a good outcome.

    The assessment of bronchial reactivity and wall remodeling in asthma plays a crucial role in better understanding such a disease and evaluating therapeutic responses. Today, multi-detector computed tomography (MDCT) makes it possible to perform an accurate estimation of bronchial parameters (lumen and wall areas) by allowing a quantitative analysis in a cross-section plane orthogonal to the bronchus axis. This paper provides the tools for such an analysis by developing a 3D investigation method which relies on 3D reconstruction of bronchial lumen and central axis computation. Cross-section images at bronchial locations interactively selected along the central axis are generated at appropriate spatial resolution. An automated approach is then developed for accurately segmenting the inner and outer bronchi contours on the cross-section images. It combines mathematical morphology operators, such as "connection cost", and energy-controlled propagation in order to overcome the difficulties raised by vessel adjacencies and wall irregularities. The segmentation accuracy was validated with respect to a 3D mathematically-modeled phantom of a pair bronchus-vessel which mimics the characteristics of real data in terms of gray-level distribution, caliber and orientation. When applying the developed quantification approach to such a model with calibers ranging from 3 to 10 mm diameter, the lumen area relative errors varied from 3.7% to 0.15%, while the bronchus area was estimated with a relative error less than 5.1%.

    Hamsters were hypophysectomized on the morning of estrus (Day 1) and injected immediately with 30 IU pregnant mare's serum (PMS). This was followed on Day 4 by the injection of an antiserum to PMS (PMS-AS) that initiated follicular atresia (Time zero). From 0 to 72 h after PMS-AS, the animals were injected with (3H)thymidine and killed 4 h later. One ovary was saved for autoradiography and histology; from the other ovary, 5-10 large antral follicles were dissected and pooled, and incorporation into DNA was determined by scintillation counting. DNA synthesis dropped sharply between 12 and 18 h, coinciding with a fall in labeling index of the cumulus oophorus and thecal endothelial cells and a sharp fall in thecal vascularity. In contrast, for the mural granulosa cells bordering on the antral cavity, labeling index dropped sharply between 8 and 12 h when thecal vascularity was still high. The earliest sign of atresia was evident by 4 h in cumulus cells when, paradoxically, DNA synthesis was still high. It took 3 days for atresia of the antral follicles to progress to advanced stages, as evidenced by pseudo-pronuclei in the free floating ovum, further erosion of the mural granulosa, and minimal DNA/follicle. However, the theca still retained its histological integrity and contained no pyknotic cells. Although by 48 h the granulosal compartment was in disarray (DNA/follicle significantly different from earlier values), the egg was still viable, as judged by maximal fluorescence after the addition of fluoroscein diacetate.

    The theca interna is a specialized stromal layer that envelops each growing ovarian follicle. It contains capillaries, fibroblasts, immune cells and the steroidogenic cells that synthesize androgens for conversion to estradiol by the neighboring granulosa cells. During reproductive life only a small number of follicles will grow to a sufficient size to ovulate, whereas the majority of follicles will undergo regression/atresia and phagocytosis by macrophages. To identify genes which are differentially regulated in the theca interna during follicular atresia, we undertook transcriptome profiling of the theca interna from healthy (n = 10) and antral atretic (n = 5) bovine follicles at early antral stages (<5 mm). Principal Component Analyses and hierarchical classification of the signal intensity plots for the arrays showed primary clustering into two groups, healthy and atretic. A total of 543 probe sets were differentially expressed between the atretic and healthy theca interna. Further analyses of these genes by Ingenuity Pathway Analysis and Gene Ontology Enrichment Analysis Toolkit software found most of the genes being expressed were related to cytokines, hormones and receptors as well as the cell cycle and DNA replication. Cell cycle genes which encode components of the replicating chromosome complex and mitotic spindle were down-regulated in atretic theca interna, whereas stress response and inflammation-related genes such as TP53, IKBKB and TGFB1 were up-regulated. In addition to cell cycle regulators, upstream regulators that were predicted to be inhibited included Retinoblastoma 1, E2 transcription factor 1, and hepatocyte growth factor. Our study suggests that during antral atresia of small follicles in the theca interna, arrest of cell cycle and DNA replication occurs rather than up- regulation of apoptosis-associated genes as occurs in granulosa cells.

    Xenon-133 lung ventilation and perfusion scans were done preoperatively after cardiac catheterization and cineangiocardiography in 19 children; 6 had pulmonary atresia with an intact ventricular septum and hypoplastic right ventricle, 4 pulmonary atresia with associated complex univentricular heart, and 9 extreme Tetralogy of Fallot. The four patients with discrepancies in the sizes of the left and right pulmonary arteries on angiography had marked asymmetry of pulmonary perfusion and ventilation-perfusion imbalance on scintigraphy. Similar degrees of asymmetry and imbalance were present in 6 of the 15 children with equal-size pulmonary vessels. Asymmetry of pulmonary perfusion and ventilation-perfusion imbalance were associated with a poor prognosis.

    Ergotamine, an ergot alkaloid, used for the treatment and prevention of migraine attacks, is considered as a teratogenic drug and, therefore, should be avoided in pregnancy. Here, we report a newborn infant with unilateral renal agenesis, urethral atresia, and pulmonary hypoplasia associated with the use of ergotamine for the treatment of migraine attacks at early pregnancy. Genitourinary anomalies in association with ergotamine usage were rarely reported and this was the third case of renal agenesia in association with ergotamine usage in literature. We suggest that ergotamine teratogenicity may be dose dependent and should be avoided in pregnancy for the possibility of genitourinary anomalies.

    An 8-day-old newborn presented with non-bilious vomiting, upper abdominal fullness, and failure to pass meconium. Plain radiographs revealed gastric pneumatosis (GP). At operation, he was found to have a non-obstructive preduodenal portal vein, preampullary duodenal atresia, asplenia, and malrotation. The baby was treated by duodeno-duodenostomy without mobilizing the portal vein and correction of the malrotation according to Ladd's procedure. He made an uneventful recovery and the GP resolved spontaneously. The malformative process was believed to have occurred at or soon after the 5th week of gestation, and the GP probably resulted from intramural air tracking through mucosal tears caused by high intragastric pressure.

    Intrathoracic gastric volvulus in the neonatal period is a rare surgical emergency. Delays in diagnosis and treatment are life-threatening due to progressive deterioration of the gastric walls. Presentation in this period can be confused with the possibility of esophageal atresia or esophageal web. The upper gastrointestinal tract contrast study is diagnostic in this disease. The authors report a case of acute intrathoracic gastric volvulus diagnosis by radiologic-contrast-study in 1-day-old girl that was confirmed at surgery. The physiopathology, classification and different presentations of this entity are briefly reviewed. PMID:25309661

    A newborn female infant born to a woman on immunosuppressive medications including mycophenolate mofetil (MMF) for a renal graft secondary to lupus nephritis presented with congenital diaphragmatic hernia (CDH) and additional findings of microtia, esophageal atresia with tracheoesophageal fistula, cleft palate, congenital heart defect, digital anomalies, and dysmorphic facial features. Pulmonary hypoplasia resulted in death at day two of life. She was presumed to have Fryns syndrome based on diagnostic criteria established for this recessive disorder with prominent features including CDH, facial anomalies, and nail hypoplasia. In retrospect, this infant's findings are more likely the result of teratogenic exposure to MMF, as more recent data have emerged linking aural atresia, digital anomalies, and dysmorphic features to this drug. To date, this is the only human report of CDH in an infant with prenatal exposure to MMF, although the manufacturer's package insert alludes to animal studies with a broad spectrum of malformations, including CDH. Thus, a teratogenic exposure can mimic a known Mendelian genetic syndrome, and caution is urged in presuming a genetic etiology for infants with potential teratogenic exposure to relatively new drugs with limited published animal data.

    Glycosylation is an essential process by which sugars are attached to proteins and lipids. Complete lack of glycosylation is not compatible with life. Because of the widespread function of glycosylation, inherited disorders of glycosylation are multisystemic. Since the identification of the first defect on N-linked glycosylation in the 1980s, there are over 40 different congenital protein hypoglycosylation diseases. This review will include defects of N-linked glycosylation, O-linked glycosylation and disorders of combined N- and O-linked glycosylation. PMID:23776380

    Purpose To determine the incidence and natural history of cataracts in children with congenital toxoplasmosis. Methods Children referred to the National Collaborative Chicago-based Congenital Toxoplasmosis Study (NCCCTS) between 1981 and 2005 were examined by ophthalmologists at predetermined times according to a specific protocol. The clinical course and treatment of patients who developed cataracts was reviewed. Results In the first year of life, 134 of 173 children examined were treated with pyrimethamine, sulfadiazine, and Leucovorin, while the remaining 39 were not treated. Cataracts occurred in 27 eyes of 20 patients (11.6%, 95% confidence interval [7.2%, 17.3%]). Fourteen cataracts were present at birth, and 13 developed postnatally. Locations of the cataracts included anterior polar (3 eyes), anterior subcapsular (6), nuclear (5), posterior subcapsular (7), and unknown (6). Thirteen cataracts were partial, 9 total, and 5 with unknown complexity. Twelve cataracts remained stable, 12 progressed, and progression was not known for 3. Five of 27 eyes had cataract surgery, with 2 of these developing glaucoma. Sixteen eyes of 11 patients had retinal detachment and cataract. All eyes with cataracts had additional ocular lesions. Conclusions In the NCCCTS cohort, 11.6% of patients were diagnosed with cataracts. There was considerable variability in the presentation, morphology, and progression of the cataracts. Associated intraocular pathology was an important cause of morbidity. PMID:18086432

    As a whole the congenital defects constitute an important section of the medical attention affecting near 3% of the population. A 15% of spontaneous abortions take place of which the greater frequency corresponds to the chromosome anomalies (25%) and the monogenic mutations (20%) and in a lesser extent to the effects of teratogenic agents. Between the genetic causes determining the congenital defects the mutations that affect genes acting in the early stages of development occupy a main place. These alterations can affect to homeotic genes or monogenic systems that act during the critical phases of the organogenesis. It seems evident that an alteration in the expression of a necessary gene for the appearance of a morphogenetic change constitutes the angular stone to understand resurging of a malformation or discapacity. In the last years has been demonstrated the importance of the teratogenic or environmental agents on the delicate internal physiological balance during the critical stages of the development. In this context must be included the inductive environmental factors inducing epigenetic modifications in the early stage of the development of the embryos produced by fertilization in vitro.

    Congenital deafness is defined as the hearing loss which is present at birth and, consequently, before speech development. It is the most prevalent sensor neural disorder in developed countries, and its incidence is estimated between 1-3 children per 1,000 newborns, of which more than 50% are attributable to genetics causes. Deafness can be classified as syndromic or non-syndromic. In the first case, it is associated with outer ear malformations and/or systemic findings. More than 400 syndromes accompanied of deafness have been described, which represent about 30% of cases of congenital hearing loss. The remaining percentage corresponds to non-syndromic cases: 75-85% are autosomal recessive, 15-24% are autosomal dominant, and 1-2% are X-linked. The evaluation of a child with deafness requires a multidisciplinary collaboration among specialists, who must coordinate themselves and give information to the affected family. The aims of establishing a diagnosis are to predict other manifestations that may suggest some syndrome and to anticipate their management, as well as to perform genetic counseling to parents and affected individuals.

    In this work we characterized the degenerative process of ovarian follicles of the bug Rhodnius prolixus challenged with the non-entomopathogenic fungus Aspergillus niger. An injection of A. niger conidia directly into the hemocoel of adult R. prolixus females at the onset of vitellogenesis caused no effect on host lifespan but elicited a net reduction in egg batch size. Direct inspection of ovaries from the mycosed insects revealed that fungal challenge led to atresia of the vitellogenic follicles. Light microscopy and DAPI staining showed follicle shrinkage, ooplasm alteration and disorganization of the monolayer of follicle cells in the atretic follicles. Transmission electron microscopy of thin sections of follicle epithelium also showed nuclei with condensed chromatin, electron dense mitochondria and large autophagic vacuoles. Occurrence of apoptosis of follicle cells in these follicles was visualized by TUNEL labeling. Resorption of the yolk involved an increase in protease activities (aspartyl and cysteinyl proteases) which were associated with precocious acidification of yolk granules and degradation of yolk protein content. The role of follicle atresia in nonspecific host-pathogen associations and the origin of protease activity that led to yolk resorption are discussed.

    Biliary Atresia and other cholestatic childhood diseases are rare conditions affecting the function and/or anatomy along the canalicular-bile duct continuum, characterised by onset of persistent cholestatic jaundice during the neonatal period. Biliary atresia (BA) is the most common among these, but still has an incidence of only 1 in 10-19,000 in Europe and North America. Other diseases such as the genetic conditions, Alagille syndrome (ALGS) and Progressive Familial Intrahepatic Cholestasis (PFIC), are less common. Choledochal malformations are amenable to surgical correction and require a high index of suspicion. The low incidence of such diseases hinder patient-based studies that include large cohorts, while the limited numbers of animal models of disease that recapitulate the spectrum of disease phenotypes hinders both basic research and the development of new treatments. Despite their individual rarity, collectively BA and other cholestatic childhood diseases are the commonest indications for liver transplantation during childhood. Here, we review the recent advances in basic research and clinical progress in these diseases, as well as the research needs. For the various diseases, we formulate current key questions and controversies and identify top priorities to guide future research.

    Familial multiple intestinal atresias is an autosomal recessive disease with or without combined immunodeficiency. In the last year, several reports have described mutations in the gene TTC7A as causal to the disease in different populations. However, exact correlation between different genotypes and various phenotypes are not clear. In this study, we report identification of novel compound heterozygous mutations in TTC7A gene in a Malay girl with familial multiple intestinal atresias and severe combined immunodeficiency (MIA-SCID) by whole exome sequencing. We found two mutations in TTC7A: one that destroyed a putative splicing acceptor at the junction of intron 17/exon 18 and one that introduced a stop codon that would truncate the last two amino acids of the encoded protein. Reviewing the recent reports on TTC7A mutations reveals correlation between the position and nature of the mutations with patient survival and clinical manifestations. Examination of public databases also suggests carrier status for healthy individuals, making a case for population screening on this gene, especially in populations with suspected frequent founder mutations.

    The association of Coats disease with intrauterine growth retardation, intracranial calcification, leukodystrophy, brain cysts, osteopenia, and gastrointestinal bleeding defines Coats plus syndrome caused by mutations in the CTC1 gene, encoding conserved telomere maintenance component 1. Here, we report on a child with exudative retinopathy, cerebral calcifications, duodenal atresia, preaxial polydactyly, micropenis, microcephaly, and short stature, in whom no mutations in CTC1 were found. Our patient shares some features seen in other diseases associated with telomere shortening including Hoyeraal-Hreidarsson and Revesz syndromes. We therefore measured telomere length by Flow-Fish which was normal. The association of duodenal atresia and microcephaly also suggested a diagnosis of Feingold syndrome. However, direct sequencing of MYCN was normal, and we did not detect any hemizygous deletion of the miR-17∼92 polycistronic miRNA cluster. To our knowledge, the phenotype we report on has not been described previously, leading us to speculate that this condition may represent a new syndrome.

    Background: Thoracoscopic treatment of esophageal atresia and tracheoesophageal fistula (EA+TEF) is accepted as a superior technique at least in cosmetic point of view but it is considered as an advance endoscopic procedure that needs a learning curve to be performed perfectly. This is the first report of Iranian group pediatric surgeons in thoracoscopic approach to EA. Methods and Materials: Since 2010, twenty four cases with EA+TEF underwent thoracoscopic approach in Sarvar Children Hospital (Mashhad -Iran). During the first 6 months, thoracoscopic approach to 6 cases of EA+TEF was converted to open procedure because of technical and instrumental problems. The first case of successful thoracoscopic EA repair was accomplished in 2010 and since then, 10 cases of EA+ TEF among 18 patients were treated successfully with thoracoscopic approach Results: Overall conversion rate was 58.3% but conversion rate after the primary learning curve period, was 35.7%. The main conversion causes include difficulties in esophageal anastomosis, limited exposure and deteriorating the patient's condition. Anastomotic leak and stenosis were observed in 20% and 40% respectively. Overall mortality rate was 4.2%. Conclusion: Thoracoscopic repair of esophageal atresia seems feasible and safe with considerable superiorities to the conventional method although acceptable results needs a prolonged learning curve and advanced endoscopic surgical skill. Clear judgment about the best surgical intervention for EA according to all cosmetic and functional outcomes needs further studies. PMID:27471677

    We describe herein a case of unilateral pulmonary agenesis (PA) with oesophageal atresia (EA)/tracheoesophageal fistula (TEF) that was diagnosed prenatally and repaired by esophagoesophagostomy with stable postoperative course. The patient was born at 34 weeks gestation, after ultrasonography at 22 weeks gestation showed possible right-sided diaphragmatic eventration or PA and EA was subsequently suspected due to hydramnios. The initial X-ray showed mediastinal shift to the right, and coil up sign of the nasogastric tube, without intracardiac anomaly. Immediately after the diagnosis of EA/TEF and unilateral PA on day 0, the patient was intubated in the operating room, and a gastrostomy tube was placed. After pulmonary status stabilized, at 4 days old, EA/TEF was repaired through a thoracotomy in the right 4 th intercostal space. The right main bronchus was noted to continue into the distal oesophagus; this fistula was ligated and divided, and a single-layer esophagoesophagostomy was performed under mild tension with one vertebral gap. The neonate was maintained on mechanical ventilation and gradually weaned to extubation at 7 days old. The postoperative course was uneventful, with the exception of prolonged jaundice that emerged at 3 months old. Laparoscopic cholangiography at that time excluded biliary atresia, and jaundice resolved spontaneously. The patient has not shown any respiratory symptoms or feeding difficulties as of the 12-month follow-up.

    Two siblings with autosomal-recessive congenital stationary night blindness were clinically blind in infancy. Both had markedly abnormal electroretinograms that, in the first child, led consultants at two university centers to make the diagnosis of Leber's congenital amaurosis. The patients had intermittent nystagmus and esotropia, but good photopic vision developed eventually. Scotopic vision was clearly defective in each child. Refractive error in both patients was close to emetropic in early infancy but became myopic by 1 year of age. Congenital stationary night blindness must be considered in the differential diagnosis of the blind infant.

    Background: Intestinal atresia has still significant morbidity in developing countries. Stomas are now not recommended in every case of intestinal atresia; primary anastomosis is the goal of surgery after resection of dilated adynamic gut. A new type of stoma formation along with primary anastomosis is being presented here. Materials and Methods: This report is based on our experience of many cases with this technique in last 12 years but all the details and long follow-up of each case is not available. However the method of surgical procedure, progress, complications, and advantages encountered have been highlighted. Results: Presently we have data of 7 patients; others are lost to follow up. Three had died with other associated problems, namely one with multiple atresias, two with septic shock and prematurity. Two stomas did not require formal closure because stoma shriveled and disappeared. Two other stomas had grown very long like a diverticulum when these were closed after 5 and 8 months. Conclusion: This technique is another attempt to decrease morbidity of patients of intestinal atresia especially in those cases where short bowel syndrome is feared after resection of proximal dilated gut.

    Bronchial provocation tests (BPTs) are useful for identifying one of the key features of asthma: bronchial hyper-responsiveness (BHR). The symptoms of asthma are not always reflective of the underlying pathophysiology of asthma and there is a need for objective tests to identify the presence and severity of BHR. A new BPT, involving the inhalation of dry powder mannitol, has recently been approved to identify BHR and is now in use as a diagnostic tool for currently active asthma. Airway sensitivity to mannitol identifies BHR that is dependent upon the presence of airway inflammation and would probably benefit from treatment with inhaled corticosteroids. The mannitol BPT is available commercially as a (single-use) test kit (Aridol/Osmohale), with the only additional requirement to perform the test being a spirometer. Accordingly, the mannitol BPT provides a point-of-need tool to identify BHR to assist in the diagnosis of asthma.

    In the airways, very complex flows occur because of different conditions and the existence of a lot of complications: constantly changing temperature and pressure during the respiration process, a normally turbulent flow in the trachea which, in heavy breathing, remains so in the first three or four generations of airways, changes of the direction of the flow over the breathing cycle, from inspiration to expiration, etc. We also know the air that flows in the bronchial tree is perturbed by several sources such as the heart and the circulatory system, the diaphragm and stomach movements, etc., which produce sound waves. Thus an acoustical analysis of the phenomenon can lead us to a physical model which could help us to better understand the phenomena and to demonstrate the importance to clinical applications such as the pneumocardiograms. To this purpose we use a thermodynamical model that originally was developed to analyze supersonic air jets to explain the production of shock waves in the bronchial tree.

    Bilateral nephroblastomatosis (NB) is an uncommon renal anomaly characterized by multiple confluent nephrogenic rests scattered through both kidneys, with only a limited number of cases reported in the medical literature. Some of these children may have associated either Perlman or Beckwith–Wiedemann syndrome and others do not demonstrate syndromic features. We report a full-term boy with anteverted nose, bilateral bronchial stenosis due to lack of cartilage, bilateral obstructive renal dysplasia and NB with glomeruloid features. The infant had visceromegaly, but neither gigantism nor hemihypertrophy. Immunohistochemistry for PAX2 (Paired box gene-2) and WT-1 (Wilms Tumor 1) were strongly positive in the areas of NB. GLEPP-1 (Glomerular Epithelial Protein) did not stain the areas of NB with a glomeruloid appearance, but was positive in the renal glomeruli as expected. We found neither associated bronchial stenosis nor the histology of NB resembling giant glomeruli in any of the reported cases of NB. PMID:25871299

    Airway anastomosis has been traditionally considered at risk for the onset of complications, particularly dehiscence with consequent infection and erosion in the adjacent vessels. Although the modifications and improvements of the surgical technique has contributed to reduce the incidence of complications, the protection and revascularization of the anastomotic site is still considered mandatory at many centers Many techniques have been proposed for encircling the bronchial anastomosis.

    Introduction Temperament, defined as the formal characteristics of behavior, is a personality trait which can influence the clinical presentation and course of bronchial asthma. It determines susceptibility to stress as well as stress coping styles. Aim The aim of the study was to assess whether healthy subjects differ from bronchial asthma patients with regard to temperamental variables and stress coping styles, and whether these factors may also differentiate patients with severe asthma from those with the milder form. The study also assesses whether the results of flow volume curve analysis correlate with temperamental traits and stress coping styles. Material and methods The study was conducted in a group of 65 asthma patients and 62 healthy controls. All underwent flow volume curve examination and psychological tests: Formal Characteristics of Behavior – Temperament Inventory (FCB-TI) and Coping in Stress Situations (CISS) questionnaire. Results Bronchial asthma patients were characterized by a lower level of briskness (“agility”) than healthy subjects (13.35 ±4.48 vs. 14.97 ±3.98, p = 0.031). The remaining temperamental traits and stress coping styles did not differ between the groups. Additionally, the forced expiratory volume in 1 s (FEV1) value was found to correlate negatively with the intensity of the emotion-oriented stress coping style, whereas FEV1 and forced vital capacity (FVC) were found to positively correlate with briskness, emotional reactivity and endurance, while a negative correlation was found with activity. Conclusions Briskness differentiates healthy subjects from bronchial asthma patients. The values obtained in FEV1 and FVC pulmonary function tests were also found to correlate with some temperamental variables. PMID:28035226

    In this report are described seven patients assessed clinically and neuropsychologically in whom mirror movements affecting predominantly the hands occurred as a congenital disorder. These mirror movements, representing a specific type of abnormal synkinesia, may arise as a hereditary condition, in the presence of a recognisable underlying neurological abnormality, and sporadically, and the seven patients provide more or less satisfactory examples of each of these three groups. Despite the apparent uniformity of the disorder, the heterogeneity and variability may be marked, examples in some of our patients including the pronounced increase in tone that developed with arm movement, and the capacity for modulation of the associated movement by alteration of neck position and bio-feedback. Various possible mechanisms are considered; these include impaired cerebral inhibition of unwanted movements, and functioning of abnormal motor pathways. Emphasis has been placed on the putative role of the direct, crossed corticomotoneurone pathways and on the unilateral and bilateral cerebral events that precede movement. PMID:7288446

    The ears of 47 selected patients with congenital sensorineural hearing loss were examined with complex-motion tomography. The patients were divided into 3 general categories: those with a recognized syndrome, those with sensorineural hearing loss unrelated to any known syndrome, and those with microtia. A great variety of inner ear anomalies was detected, but rarely were these characteristic of a particular clinical entity. The most common finding was the Mondini malformation or one of its variants. Isolated dysplasia of the internal auditory canal or the vestibular aqueduct may be responsible for sensorineural hearing loss in some patients. Patients with microtia may also have severe inner ear abnormalities despite the fact that the outer and inner ears develop embryologically from completely separate systems.

  9. Congenital adrenal hyperplasia.

    PubMed

    Merke, Deborah P; Bornstein, Stefan R

    Congenital adrenal hyperplasia (CAH) due to deficiency of 21-hydroxylase is a disorder of the adrenal cortex characterised by cortisol deficiency, with or without aldosterone deficiency, and androgen excess. Patients with the most severe form also have abnormalities of the adrenal medulla and epinephrine deficiency. The severe classic form occurs in one in 15,000 births worldwide, and the mild non-classic form is a common cause of hyperandrogenism. Neonatal screening for CAH and gene-specific prenatal diagnosis are now possible. Standard hormone replacement fails to achieve normal growth and development for many children with CAH, and adults can experience iatrogenic Cushing's syndrome, hyperandrogenism, infertility, or the development of the metabolic syndrome. This Seminar reviews the epidemiology, genetics, pathophysiology, diagnosis, and management of CAH, and provides an overview of clinical challenges and future therapies.

    Congenitally corrected transposition of the great arteries is a rare defect characterized by discordant atrioventricular and ventriculoarterial connections. Symptoms result from one or a combination of associated cardiovascular malformations, including ventricular septal defect, pulmonary stenosis or atresia, tricuspid valve dysfunction, dextrocardia, hypoplastic left or right ventricle. Correcting exclusively the associated defects, leaving the morphologic right ventricle in systemic position, will determine the patient's life-long prognosis. Anatomic repair by double switch technique may improve survival of patients with congenitally corrected transposition of the great arteries by establishing the morphologic left ventricle in the systemic circulation. A 3-year-old girl with congenitally corrected transposition of the great arteries, ventricular septal defect, hypoplastic right ventricle, and previous palliative procedure was corrected by double switch technique and patch closure of ventricular septal defect. The authors prefer the double switch procedure inspite of its many surgical challenges because it has very good long-term outcome. The more simple surgery namely the operation of only associated cardiac defects will involve the possibility of deterioration of right ventricular function.

    Recently, cells isolated from airways have been used to characterize precisely the electrophysiological properties of this smooth muscle and to describe the changes in cytosolic calcium concentration ([Ca2+]i) occurring upon agonist stimulation. Although most studies have produced consistent results in terms of types of ion channel and pathways of calcium signalling implicated in the mechanical activity of airways, there are differences according to (i) the site along the bronchial tree (trachea vs. bronchi); (ii) the proliferating status of the cells (freshly isolated vs. cultured) and (iii) the species (human vs. animals). With regard to the electrophysiological properties of airway smooth muscle, the contribution to [Ca2+]i rise of Ca2+ influx through L-type voltage-dependent calcium channels depends on the balance between depolarization related to non-specific cation channel and/or chloride channel activation and hyperpolarization related to activation of a variety of potassium channels. Most of the above-mentioned channels appear to be controlled, directly or indirectly, by agonists in human bronchial smooth muscle. With regard to calcium signalling, the pattern of agonist-induced [Ca2+]i responses, the so-called [Ca2+]i oscillations, has been observed recently in freshly isolated airway smooth muscle cells. The role and the calcium sources involved in these oscillations in human bronchial smooth muscle are currently being investigated.

    Background Although benzalkonium chloride (BAC)-induced bronchoconstriction occurs in patients with bronchial asthma, BAC-containing nebulizer solutions are still being used in daily practice in Korea. The aim of this study was to evaluate the effects of inhaled aqueous solutions containing BAC. Methods Thirty subjects with bronchial asthma and 10 normal controls inhaled up to three 600 µg nebulized doses of BAC using a jet nebulizer. FEV1 (forced expiratory volume at one second) was measured 15 minutes after each dose. Inhalations were repeated every 20 minutes until FEV1 decreased by 15% or more (defined as BAC-induced bronchoconstriction) or the 3 doses were administered. Results The percent fall in FEV1 in response to BAC inhalation was significantly higher in asthmatics than in normal subjects (p<0.05). BAC administration in subjects with asthma reached a plateau (maximal effect). BAC-induced bronchoconstriction was found in 6 asthmatics (20%), with two responders after the 2nd inhalation and after the 3rd inhalation. The percent fall in FEV1 in response to the 1st inhalation of BAC was significantly higher in asthmatics with higher bronchial hyperresponsiveness (BHR) than in those with lower BHR. Conclusions This study suggests that the available multi-dose nebulized solution is generally safe. However, significant bronchoconstriction can occur at a relatively low BAC dose in asthmatics with severe airway responsiveness. PMID:18309682

    Bronchial colonisation is frequently reported in patients with lung cancer, and has a potential impact on therapeutic management and prognosis. We aimed to prospectively define the prevalence and nature of bronchial colonisation in patients at the time of diagnosing lung cancer. 210 consecutive patients with lung cancer underwent a flexible bronchoscopy for lung cancer. The type and frequency of bacterial, mycobacterial and fungal colonisation were analysed and correlated with the patients' and tumours' characteristics. Potential pathogens were found in 48.1% of samples: mainly the Gram-negative bacilli Escherichia coli (8.1%), Haemophilus influenzae (4.3%) and Enterobacter spp. (2.4%); Gram-positive cocci, Staphylococcus spp. (12.9%) and Streptococcus pneumoniae (3.3%); atypical mycobacteria (2.9%); Candida albicans (42.9%); and Aspergillus fumigatus (6.2%). Aged patients (p=0.02) with chronic obstructive pulmonary disease (p=0.008) were significantly more frequently colonised; however, tumour stage, atelectasis, bronchial stenosis and abnormalities of chest radiography were not associated with a higher rate of colonisation. Squamous cell carcinoma tended to be more frequently colonised than other histological subtypes. Airway colonisation was reported in almost half of patients presenting with lung cancer, mainly in fragile patients, and was significantly associated with worse survival (p=0.005). Analysing colonisation status of patients at the time of diagnosis may help improve the management of lung cancer.

    The follicle destiny towards ovulation or atresia is multi-factorial in nature and involves outcries, paracrine and endocrine factors that promote cell proliferation and survival (development) or unchain apoptosis as part of the atresia process. In several types of cells, sphingosine-1-phospate (S1P) promotes cellular proliferation and survival, whereas ceramide (CER) triggers cell death, and the S1P/CER ratio may determine the fate of the cell. The aim of present study was to quantify S1P and CER concentrations and their ratio in bovine antral follicles of 8 to 17 mm classified as healthy and atretic antral follicles. Follicles were dissected from cow ovaries collected from a local abattoir. The theca cell layer, the granulosa cells and follicular fluid were separated, and 17β-estradiol (E2) and progesterone (P4) concentrations were measured in the follicular fluid by radioimmunoassay. Based on the E2/P4 ratio, the follicles were classified as healthy (2.2±0.3) or atretic (0.2±0.3). In both follicular compartments (granulosa and theca cell layer), sphingolipids were extracted and S1P and CER concentrations were quantified by HPLC (XTerra RP18; 5 µm, 3.0×150 mm column). Results showed that in both follicular compartments, S1P concentrations were higher in healthy antral follicles than in atretic antral follicles (P<0.05). The concentration of CER in the granulosa cells was higher in atretic antral follicles than in healthy antral follicles, but no differences were observed in the theca cell layer. The S1P/CER ratio in both follicular compartments was also higher in healthy antral follicles. Interestingly, in these follicles, there was a 45-fold greater concentration of S1P than CER in the granulosa cells (P<0.05), whereas in the theca cell layer, S1P had only a 14-fold greater concentration than CER when compared with atretic antral follicles. These results suggest that S1P plays a role in follicle health, increasing cellular proliferation and survival. In

    Background The Senegalese sole (Solea senegalensis) is a marine flatfish of increasing commercial interest. However, the reproduction of this species in captivity is not yet controlled mainly because of the poor knowledge on its reproductive physiology, as it occurs for other non-salmonid marine teleosts that exhibit group-synchronous ovarian follicle development. In order to investigate intra-ovarian molecular mechanisms in Senegalese sole, the aim of the present study was to identify differentially expressed genes in the ovary during oocyte growth (vitellogenesis), maturation and ovarian follicle atresia using a recently developed oligonucleotide microarray. Results Microarray analysis led to the identification of 118 differentially expressed transcripts, of which 20 and 8 were monitored by real-time PCR and in situ hybridization, respectively. During vitellogenesis, many up-regulated ovarian transcripts had putative mitochondrial function/location suggesting high energy production (NADH dehydrogenase subunits, cytochromes) and increased antioxidant protection (selenoprotein W2a), whereas other regulated transcripts were related to cytoskeleton and zona radiata organization (zona glycoprotein 3, alpha and beta actin, keratin 8), intracellular signalling pathways (heat shock protein 90, Ras homolog member G), cell-to-cell and cell-to-matrix interactions (beta 1 integrin, thrombospondin 4b), and the maternal RNA pool (transducer of ERBB2 1a, neurexin 1a). Transcripts up-regulated in the ovary during oocyte maturation included ion transporters (Na+-K+-ATPase subunits), probably required for oocyte hydration, as well as a proteinase inhibitor (alpha-2-macroglobulin) and a vesicle calcium sensor protein (extended synaptotagmin-2-A). During follicular atresia, few transcripts were found to be up-regulated, but remarkably most of them were localized in follicular cells of atretic follicles, and they had inferred roles in lipid transport (apolipoprotein C-I), chemotaxis

  17. Transcriptome profiling of granulosa cells from bovine ovarian follicles during atresia

    PubMed Central

    2014-01-01

    Background The major function of the ovary is to produce oocytes for fertilisation. Oocytes mature in follicles surrounded by nurturing granulosa cells and all are enclosed by a basal lamina. During growth, granulosa cells replicate and a large fluid-filled cavity (the antrum) develops in the centre. Only follicles that have enlarged to over 10 mm can ovulate in cows. In mammals, the number of primordial follicles far exceeds the numbers that ever ovulate and atresia or regression of follicles is a mechanism to regulate the number of oocytes ovulated and to contribute to the timing of ovulation. To better understand the molecular basis of follicular atresia, we undertook transcriptome profiling of granulosa cells from healthy (n = 10) and atretic (n = 5) bovine follicles at early antral stages (< 5 mm). Results Principal Component Analysis (PCA) and hierarchical classification of the signal intensity plots for the arrays showed primary clustering into two groups, healthy and atretic. These analyses and size-frequency plots of coefficients of variation of signal intensities revealed that the healthy follicles were more heterogeneous. Examining the differentially-expressed genes the most significantly affected functions in atretic follicles were cell death, organ development, tissue development and embryonic development. The overall processes influenced by transcription factor gene TP53 were predicted to be activated, whereas those of MYC were inhibited on the basis of known interactions with the genes in our dataset. The top ranked canonical pathway contained signalling molecules common to various inflammatory/fibrotic pathways such as the transforming growth factor-β and tumour necrosis factor-α pathways. The two most significant networks also reflect this pattern of tissue remodelling/fibrosis gene expression. These networks also contain molecules which are present in the canonical pathways of hepatic fibrosis/hepatic stellate cell activation and transforming

    The objective of study is to determine the thickness of bronchial walls of clinically diagnosed asthmatic cats using high resolution computed tomography (HRCT) compared to that of healthy cats. The bronchial walls and pulmonary arteries were measured in healthy 16 cats and clinically asthmatic 4 cats. The bronchial walls and pulmonary arteries were measured under general anesthesia with positive pressure inspiration using HRCT. In healthy and asthmatic cats, bronchial lumen to the artery ratio (BA ratio), the ratio of bronchial wall thickness to bronchial diameter (TD ratio) and ratio of bronchial wall thickness to pulmonary artery (TA ratio) were measured. The mean BA ratio, TD ratio and TA ratio in healthy cats were 0.86 ± 0.12, 0.18 ± 0.02 and 0.25 ± 0.05, respectively. Under the same condition, the mean BA ratio, TD ratio and TA ratio in asthmatic cats were 0.93 ± 0.21, 0.22 ± 0.24 and 0.37 ± 0.06. The TD ratio and TA ratio in asthmatic cats were significantly higher than healthy cats (P<0.001). BA ratio was not significantly different in both groups (P>0.05). The evaluation of bronchial wall thickness by HRCT could be useful for diagnosis of disease of bronchial wall thickening, such as feline asthma. PMID:28163274

    Background To explore the effectiveness of video-assisted thoracoscopic surgery (VATS) bronchial sleeve resection and reconstruction. Methods The clinical data of patients who had received VATS bronchial sleeve lobectomy in our center from January 2008 to February 2015 were retrospectively analyzed. Results Totally 118 patients (105 men and 13 women) received the VATS bronchial sleeve lobectomy. The procedures included sleeve resection of right upper lobe (n=59), right middle lobe (n=7), right lower lobe (n=8), left upper lobe (n=34), and left lower lobe (n=10). The lesions were confirmed to be squamous cell carcinoma (n=68), adenocarcinoma (n=16), mucoepidermoid carcinoma (n=8), adenosquamous carcinoma (n=7), large cell carcinoma (n=1), carcinoids (n=5), and others (n=13; including small cell carcinoma, pleomorphic carcinoma, and inflammatory myofibroblastic tumor). Operations lasted 118–223 min [mean ± standard deviations (SD): 124.00±31.75 min]. The length of removed bronchus was 1.50–2.00 cm (mean ± SD: 1.75±0.26 cm). The duration of bronchial anastomosis (from the first puncture to the completion of knotting) was 15–42 min (mean ± SD: 30.20±7.97 min). The number of dissected lymph node stations (at least three mediastinal lymph node stations, including station 7) was 5–9 stations (mean ± SD: 6.50±1.18 min). The number of dissected lymph nodes was 10–46 (mean ± SD: 26.00±10.48). The intraoperative blood loss was 20–400 mL (mean ± SD: 71.00±43.95 mL), and no blood transfusion was performed. All patients were observed in intensive care unit (ICU) for 1 day. Postoperative drainage was performed for 3–8 days (mean ± SD: 5.00±1.49 days). Postoperative hospital stay was 3–8 days (mean ± SD: 5.10±2.07 days). Conclusions VATS bronchial sleeve resection and reconstruction is a safe and feasible technique. PMID:27076954

    Photoaversion is a prominent symptom of a number of infantile genetic ocular disorder such as congenital glaucoma, aniridia, albinism, and cone dystrophies including achromatopsia. Photoaversion has not been widely recognized as a clinical feature of Leber's congenital amaurosis. We present two patients who were diagnosed clinically with achromatopsia because of nystagmus, absent color vision, reduced visual acuity, and moderately severe photoaversion in the absence of anterior segment abnormalities. The photopic and scotopic responses of the electroretinogram (E R G) were nonrecordable in both patients indicating involvement of both cone and rod systems. The diagnosis was then revised to one of Leber's congenital amaurosis. Photoaversion can be a prominent clinical feature in some patients with Leber's congenital amaurosis. The E R G clinches the diagnosis. These patients may constitute a distinct genetic subtype of the disease and molecular genetic studies will help resolve this issue.

    1966-01-01

    The causation of congenital malformation is receiving increased study. In Canada, epidemiologic surveys are being planned, based upon the institution of Provincial Registries to which physicians and other agencies will voluntarily report cases coming to their attention. The literature in regard to prevalence studies of congenital cardiac defects in school children is reviewed. Over the past 25 years, studies employing the proposed technique demonstrated a rising trend, from 1.4 per 1000 to 2.6 per 1000. By contrast, specific surveys for congenital cardiac defect carried out by expert personnel using radiographs and electrocardiographs, resulted in essentially uniform rates, approximating 5 to 6 per 1000. It is concluded that the latter is a superior technique of epidemiologic survey over the “Central Registry” method, and should command a due proportion of health resources directed towards congenital malformation research.

The most severe congenital heart diseases are less frequent in girls, but when they are present in females, they are linked to a higher surgical mortality rate, due perhaps to lower weight at birth and to the prevalence of extracardiac malformations and/or of associated genetic syndromes. On the other hand, in adults, surgery for congenital heart disease is at higher risk in males, and so the long-term survival rate is higher in females. Particular psychological attitudes, a higher incidence of pulmonary hypertension, as well as specific problems linked to the reproductive function characterize congenital heart disease in adult women. The knowledge and analysis of these data are essential for a correct management of congenital heart disease in neonates, children and adults.

    From June 1st, 1989 to May 31st, 1990, 16,987 consecutive newborns were examined at the No. 48 Gynecological Pediatric Hospital of the IMSS National Medical Center, looking for external congenital malformations including esophageal atresias, anorectal malformations and congenital hip luxations, all easily detected during a routine exploration. Each deformed newborn assigned two control patients the following two newborn babies showing no birth defects. 308 deformed newborns were detected, an incidence of 1.81%. Among the most frequent defects were midline flat hemangiomas, polyotia, Down syndrome, congenital hip luxation and myelomeningocele. The only significant statistical difference found with respect to the control group was a greater family history of defects in the case group (P less than 0.0001). When comparing our results with those from other studies, including a study done locally 15 years ago, we found differences among specific malformations: congenital hip malformation, polydactylia, foot deformities, flat hemangiomas, nevus and polyotias. Yet, the overall frequency of defects found was similar.

    Choanal atresia (CA) is a craniofacial malformation characterized by obstruction of the posterior nasal aperture, resulting in laborious respiratory inspiration and exhalation. Alpaca crias with CA typically develop fatal pneumonia, frequently as the result of milk aspiration during nursing, and euthanasia is usually inevitable. Nonsense or missense mutations in the CHD7 gene cause a comparable condition (CHARGE syndrome) in humans. In this study, the coding region of CHD7 was sequenced in six CA-affected alpacas. Forty-nine sequence variants were identified, of which 10 would result in amino acid changes (non-synonymous), some with potentially deleterious effects. However, none of the observed variants would result in the obvious deleterious effects caused by nonsense or missense mutations. Although a role for CHD7 mutations in CA cannot be definitively dismissed, these do not appear to be the primary cause of CA in alpacas.

    IMPORTANCE Biliary atresia is the most common cause of end-stage liver disease in children. Controversy exists as to whether use of steroids after hepatoportoenterostomy improves clinical outcome. OBJECTIVE To determine whether the addition of high-dose corticosteroids after hepatoportoenterostomy is superior to surgery alone in improving biliary drainage and survival with the native liver. DESIGN, SETTING, AND PATIENTS The multicenter, double-blind Steroids in Biliary Atresia Randomized Trial (START) was conducted in 140 infants (mean age, 2.3 months) between September 2005 and February 2011 in the United States; follow-up ended in January 2013. INTERVENTIONS Participants were randomized to receive intravenous methylprednisolone (4 mg/kg/d for 2 weeks) and oral prednisolone (2 mg/kg/d for 2 weeks) followed by a tapering protocol for 9 weeks (n = 70) or placebo (n = 70) initiated within 72 hours of hepatoportoenterostomy. MAIN OUTCOMES AND MEASURES The primary end point (powered to detect a 25% absolute treatment difference) was the percentage of participants with a serum total bilirubin level of less than 1.5 mg/dL with his/her native liver at 6 months posthepatoportoenterostomy. Secondary outcomes included survival with native liver at 24 months of age and serious adverse events. RESULTS The proportion of participants with improved bile drainage was not statistically significantly improved by steroids at 6 months posthepatoportoenterostomy (58.6% [41/70] of steroids group vs 48.6% [34/70] of placebo group; adjusted relative risk, 1.14 [95% CI, 0.83 to 1.57]; P = .43). The adjusted absolute risk difference was 8.7% (95% CI, −10.4% to 27.7%). Transplant-free survival was 58.7% in the steroids group vs 59.4% in the placebo group (adjusted hazard ratio, 1.0 [95% CI, 0.6 to 1.8]; P = .99) at 24 months of age. The percentage of participants with serious adverse events was 81.4% [57/70] of the steroids group and 80.0% [56/70] of the placebo group (P > .99); however

    This article describes a series of 21 consecutive cases, each involving a solitary median maxillary central incisor; the patients were seen in the Department of Dentistry or the Victorian Clinical Genetics Unit, Murdoch Institute, at the Royal Children's Hospital, Melbourne, from 1966 to 1997. The spectrum of anomalies and associated features present in these cases--solitary median maxillary central incisor, choanal atresia, and holoprosencephaly--is described, and the literature related to the features, including genetic studies in these conditions, is reviewed. We relate our findings in these cases to current knowledge of developmental embryology. It is hoped that the findings, together with our interpretation of them, will help to clarify understanding of solitary median maxillary central incisor syndrome. This syndrome was previously considered a simple midline defect of the dental lamina, but it is now recognized as a possible predictor of holoprosencephalies of varying degrees in the proband, in members of the proband's family, and in the family's descendants.

    Introducción: la atresia de vías biliares (AVB) es el resultado final de un proceso destructivo, idiopático e inflamatorio que afecta los conductos biliares intra y extrahepáticos, dando lugar a fibrosis y progresivamente a cirrosis biliar. El objetivo fue identificar los factores relacionados con la mortalidad en niños con AVB. Métodos: estudio observacional, longitudinal, analítico y retrospectivo aplicado a pacientes con diagnóstico de atresia de vías biliares atendidos entre los años 2008 y 2012 en hospital de tercer nivel. Resultados: se incluyeron un total de 66 pacientes con AVB; 49 (74.2 %) fueron niñas. Solo se realizó operación de Kasai a 47, la edad al momento del envío fue de 4.5 meses. Al comparar los grupos con y sin Kasai, resultaron estadísticamente significativas la edad menor al momento del envío y la edad del diagnóstico, así como un menor puntaje en el PELD score y en el CHILD-PUGH para el grupo con Kasai. Los pacientes que fallecieron tuvieron una calificación de PELD estadísticamente mayor (mediana 20) que los que vivieron (mediana 13), p = 0.004. El factor relacionado directamente con la mortalidad, fue el antecedente de cirugía de Kasai con una RM de 0.17 (IC 95 %: 0.04-0.71; p = 0.016). Conclusiones: el pronóstico de los niños con AVB continúa siendo sombrío, dado que se diagnostican en etapas tardías. El factor más importante relacionado con la mortalidad en estos pacientes es la realización de cirugía de Kasai.

    While many long-term complications of esophageal atresia (EA) have been well investigated, little is known about feeding difficulties in children after surgical correction of EA and its impact on caregivers. This study investigates the feeding behaviors of children with EA through a validated feeding questionnaire. The Montreal Children's Hospital Feeding Scale (MCH-FS) was filled out by the primary caregiver during patient follow-up visits in the multidisciplinary EA clinic. Demographic information, EA subtype, associated anomalies and outcomes were recorded. Results were compared between groups and to a normative sample. Thirty caregivers have completed the MCH-FS; 26 patients had type C atresia (86.7%). In comparison to controls, 17.5% of EA cases are one standard deviation above the mean feeding difficulty score, while 6.7% (n = 2) cases are greater than two standard deviations above normative values. Typical EA patients (type C who were not born <30 weeks) had mean MCH-FS scores in the subclinical range, whereas one extremely premature child and the patients with non-type C EA (n = 4) all had scores in the severe range. Feeding difficulties of patients with typical EA appear mild. Likely explanations include the use of early protocolized care and intensive multidisciplinary care in follow up. Nonetheless, patients with complicated EA (non-type C) and their caregivers tend to experience significant feeding difficulties. Early targeted care may be required for this patient subset, and additional cases will be investigated to confirm these preliminary findings and explore further risk factors of feeding problem in this cohort.

  15. Adult sea lamprey tolerates biliary atresia by altering bile salt composition and renal excretion

    The sea lamprey (Petromyzon marinus) is a genetically programmed animal model for biliary atresia as it loses its bile ducts and gallbladder during metamorphosis. However, in contrast to patients with biliary atresia or other forms of cholestasis who develop progressive disease, the post-metamorphosis lampreys grow normally to adult size. To understand how the adult lamprey thrives without the ability to secrete bile, we examined bile salt homeostasis in larval and adult lampreys. Adult livers were severely cholestatic with levels of bile salts >1 mM, but no evidence of necrosis, fibrosis, or inflammation. Interestingly, both larvae and adults had normal plasma levels (~10 μM) of bile salts. In larvae, petromyzonol sulfate (PZS) was the predominant bile salt, whereas the major bile salts in adult liver were sulfated C27 bile alcohols. Cytotoxicity assays revealed that PZS was highly toxic. Pharmacokinetic studies in free-swimming adults revealed that ~35% of intravenously injected bromosulfophthalein (BSP) was eliminated over a 72 hr period. Collection of urine and feces demonstrated that both endogenous and exogenous organic anions, including biliverdin, bile salts and BSP, were predominantly excreted via the kidney with minor amounts also detected in feces. Gene expression analysis detected marked up-regulation of orthologs of known organic anion and bile salt transporters in the kidney with lesser effects in the intestine and gills in adults compared to larvae. These findings indicate that adult lampreys tolerate cholestasis by altering hepatic bile salt composition, while maintaining normal plasma bile salt levels predominantly through renal excretion of bile products. Therefore, we conclude that strategies to accelerate renal excretion of bile salt and other toxins should be beneficial for patients with cholestasis. PMID:23175353

    We investigated the effects of follicle-stimulating hormone (FSH) on atresia of the dominant follicle and changes in relevant apoptosis genes in granulosa cells of dominant follicles regulated by FSH in vivo. Four-week-old mice were administered FSH by intraperitoneal injection to induce follicular maturation. Granulosa cells of dominant follicles were collected at 48, 72, and 96 h after the first FSH injection. Phosphate-buffered saline was injected as a control. The mRNA levels of relevant granulosa cell apoptosis genes were examined by real-time quantitative polymerase chain reaction, and apoptosis of granulosa cells in dominant ovarian follicles was determined by the terminal deoxynucleotidyl transferase dUTP nick-end labeling (TUNEL) assay. Apoptosis in granulosa cells of dominant follicles was almost TUNEL-negative at 48, 72-66, 72, and 96-90 h after the first FSH injection, but granulosa cell apoptosis in dominant follicles was clearly detected at 96, 102, and 102-96 h by TUNEL. The BIM, caspase-3, and caspase-9 mRNA expression levels were significantly lower after FSH treatment at 72-66 and 96-90 h, compared with that at 72 and 96 h (P < 0.05). Caspase-8 and FasL mRNA expressions did not respond to FSH. FSH rescued granulosa cells from apoptosis when the relevant apoptosis genes were upregulated in early atretic follicles. FSH did not rescue granulosa cells from apoptosis if the DNA was cut into fragments by endonucleases. Thus, the rescue by FSH of granulosa cells from apoptosis and dominant follicle atresia may be accomplished by inhibition of apoptosis in mitochondria.

    Objective This report documents the authors' experiences in the management of “complex” jejunoileal atresia (JIA) and provides a review of the recent literature on “simple” and “complex” JIA. Materials and Methods This is a retrospective study of eight cases of “complex” JIA managed at the Pediatric Surgical Unit of Infermi Hospital in Rimini from 2002 to 2012. The inclusion criteria are all cases of JIA associated with distal bowel deformities and Types IIIb or IV. One patient had gastroschisis. Results The authors of this study performed primary anastomosis on three patients and enterostomies on five patients. In one case in which a patient presented with gastroschisis, the V.A.C. Therapy System (KCI Medical Ltd., Langford Locks, Kidlington, UK) was used to close the abdominal defect. All patients needed central venous catheter (CVC). Total parenteral nutrition (TPN) was administered for a mean of 12 days. Oral feeding was introduced on mean day 7 (7.71 ± 3.40 standard deviation). Patients with enterostomy began extracorporeal stool transport on mean day 14. No outcomes resulted in short bowel syndrome (SBS). The mortality rate was zero. The authors of this study performed more enterostomies and CVC insertion than other authors in “complex” JIA and reported a percentage of SBS, complications of TPN, and start of oral feeding comparable to “simple” case reported by other authors. Conclusions The results demonstrate that the complexity of JIA alone is not associated to a worsening prognosis than simple atresia if the surgical and clinical approach is as conservative as possible.

    Background: Perforation of pulmonary valve using radiofrequency ablation in pulmonary atresia with intact ventricular septum (PA IVS) is a treatment of choice. However, significant cost of the equipment limits its utility, especially in the developing economies. Objective: To assess the feasibility, safety, and efficacy of perforation of pulmonary valve using chronic total occlusion (CTO) wires in patients with PA IVS as an alternative to radiofrequency ablation. Methods: This is a single-center, nonrandomized, retrospective study conducted during June 2008 to September 2015. Twenty-four patients with PA IVS were selected for the procedure during the study period. The median age and weight of the study population were 8. days and 2.65 kg, respectively. Four patients were excluded after right ventricular angiogram as they showed right ventricular-dependent coronary circulation. The pulmonary valve perforation was attempted using various types of CTO wires based on the tip load with variable penetrating characteristics. Results: The procedure was successful in 16 of twenty patients using CTO wires: Shinobi in nine, Miracle in four, CROSS-IT in two, and Conquest Pro in one. Two patients had perforation of right ventricular outflow tract (RVOT). Pericardiocentesis was required in one patient to relieve cardiac tamponade. Later, the same patient underwent successful hybrid pulmonary valvotomy. The other patient underwent ductus arteriosus (DA) stenting. Balloon atrial septostomy was needed in three cases with systemic venous congestion. Desaturation was persistent in five cases necessitating DA or RVOT stenting to augment pulmonary blood flow. There were two early and two late deaths. The mean follow-up was 22.66 ± 16 months. Three patients underwent one and half ventricle repair and one Blalock–Taussig shunt during follow-up. Conclusion: Perforation of the pulmonary valve can be done successfully using CTO wires in selected cases of pulmonary atresia with intact

    Background: Congenital epidermolysis bullosa (CEB) is a rare genodermatosis. The digestive system is very frequently associated with skin manifestations. Pyloric atresia (PA) and oesophageal stenosis (OS) are considered the most serious digestive lesions to occur. The aim of this work is to study the management and the outcome of digestive lesions associated to CEB in four children and to compare our results to the literature. Patients and Methods: A retrospective study of four observations: Two cases of PA and two cases of OS associated to CEB managed in the Paediatric Surgery Department of Fattouma Bourguiba Teaching Hospital in Monastir, Tunisia. Results: Four patients, two of them are 11 and 8 years old, diagnosed as having a dystrophic epidermolysis bullosa since the neonatal period. They were admitted for the investigation of progressive dysphagia. Oesophageal stenosis was confirmed by an upper contrast study. Pneumatic dilation was the advocated therapeutic method for both patients with afavourable outcome. The two other patients are newborns, diagnosed to have a CEB because of association of PA with bullous skin lesions with erosive scars. Both patients had a complete diaphragm excision with pyloroplasty. They died at the age of 4 and 3 months of severe diarrhoea resistant to medical treatment. Conclusion: Digestive lesions associated to CEB represent an aggravating factor of a serious disease. OS complicating CEB is severe with difficult management. Pneumatic dilatation is the gold standard treatment method. However, the mortality rate in PA with CEB is high. Prenatal diagnosis of PA is possible, and it can help avoiding lethal forms.

    Objective: To investigate the clinical value of acoustic radiation force impulse (ARFI)technique in predicting esophageal and gastric varices in patients with biliary atresia after Kasai portoenterostomy. Methods: A total of 42 patients with biliary atresia after Kasai portoenterostomy were collected from September 2015 to May 2016 in Tianjin First Central Hospital.ARFI technique was used to measure the stiffness of liver and spleen, and 28 healthy children as control.According to the result of CT examination , patients with biliary atresia were divided into two groups , twenty-three patients with esophageal and gastric varices(A group) and nineteen patients without esophageal and gastric varices (B group), Comparing the difference of liver and spleen stiffness between the two groups.The ROC curve analysis was carried out to test the diagnostic power of effective parameter. Results: The ARFI value of liver (2.98±0.80) m/s and spleen (3.00±0.33) m/s of patients with biliary atresia was significantly higher than that of control group((1.10±0.16) m/s, (2.12±0.32) m/s), the differences had statistical significance (both P<0.01). Between group A and group B, the spleen ARFI value of group A(3.16±0.26) m/s was higher than group B(2.83±0.32) m/s, the difference had statistical significance (P<0.01), whereas there was no statistical difference of liver ARFI value between two group((2.93±0.65), (3.02±0.96) m/s)(P>0.05). The cut-off ARFI value of spleen to diagnose esophageal and gastric varices in biliary atresia was 3.02 m/s, and the biggest area under the ROC curve, sensitivity, and specificity were 0.81, 78.6% and 84.5%, respectively. Conclusion: ARFI can be used as a noninvasive method to predict the presence of esophageal and gastric varices in patients with biliary atresia after Kasai portoenterostomy.

    2009-06-01

    Prothrombin deficiency is among the rarest inherited coagulation disorders, with a prevalence of approximately 1:2,000,000. Two main phenotypes can be distinguished: (1) hypoprothrombinemia (type I deficiency), characterized by concomitantly low levels of activity and antigen; and (2) dysprothrombinemia (type II deficiency), characterized by the normal or near-normal synthesis of a dysfunctional protein. In some cases, hypoprothrombinemia associated with dysprothrombinemia was also described in compound heterozygous defects. No living patient with undetectable plasma prothrombin has been reported to date. Prothrombin is encoded by a gene of approximately 21 kb located on chromosome 11 and containing 14 exons. Forty different mutations have been identified and characterized in prothrombin deficiency. Many of them surround the catalytic site, whereas another "hot spot" is localized in the recognition domain called anion binding exosite I, also called fibrinogen recognition site. Recently, mutations were identified also in the Na (+)-binding loop and in the light A-chain of thrombin. Most hypoprothrombinemia-associated mutations are missense, but there are also nonsense mutations leading to stop codons and one single nucleotide deletion. Finally, the main aspects of clinical manifestations and therapy of congenital prothrombin deficiency are presented and discussed.

  7. Singing in congenital amusia.

    Dalla Bella, Simone; Giguère, Jean-François; Peretz, Isabelle

    2009-07-01

    Congenital amusia is a musical disorder characterized by impaired pitch perception. To examine to what extent this perceptual pitch deficit may compromise singing, 11 amusic individuals and 11 matched controls were asked to sing a familiar tune with lyrics and on the syllable /la/. Acoustical analysis of sung renditions yielded measures of pitch accuracy (e.g., number of pitch errors) and time accuracy (e.g., number of time errors). The results revealed that 9 out of 11 amusics were poor singers, mostly on the pitch dimension. Poor singers made an anomalously high number of pitch interval and contour errors, produced pitch intervals largely deviating from the score, and lacked pitch stability; however, more than half of the amusics sang in-time. Amusics' variability in singing proficiency was related to their residual pitch perceptual ability. Thus, their singing deficiency might be a consequence of their perceptual deficit. Nevertheless, there were notable exceptions. Two amusic individuals, despite their impoverished perception, sang proficiently. The latter findings are consistent with the existence of separate neural pathways for auditory perception and action.

    2009-02-01

    Congenital insensitivity to pain (CIP) is a rare syndrome with various clinical expressions, characterized by a dramatic impairment of pain perception since birth. In the 1980s, progress in nerve histopathology allowed to demonstrate that CIP was almost always a manifestation of hereditary sensory and autonomic neuropathies (HSAN) involving the small-calibre (A-delta and C) nerve fibres which normally transmit nociceptive inputs along sensory nerves. Identification of the genetic basis of several clinical subtypes has led to a better understanding of the mechanisms involved, emphasizing in particular the crucial role of nerve growth factor (NGF) in the development and survival of nociceptors. Recently, mutations of the gene coding for the sodium channel Nav1.7--a voltage-dependent sodium channel expressed preferentially on peripheral nociceptors and sympathetic ganglia--have been found to be the cause of CIP in patients showing a normal nerve biopsy. This radical impairment of nociception mirrors the hereditary pain syndromes associated with "gain of function" mutations of the same ion channel, such as familial erythromelalgia and paroxysmal extreme pain disorder. Future research with CIP patients may identify other proteins specifically involved in nociception, which might represent potential targets for chronic pain treatment. Moreover, this rare clinical syndrome offers the opportunity to address interesting neuropsychological issues, such as the role of pain experience in the construction of body image and in the empathic representation of others' pain.

  9. Congenital lipoid adrenal hyperplasia

    PubMed Central

    2014-01-01

    Congenital lipoid adrenal hyperplasia (lipoid CAH) is the most fatal form of CAH, as it disrupts adrenal and gonadal steroidogenesis. Most cases of lipoid CAH are caused by recessive mutations in the gene encoding steroidogenic acute regulatory protein (StAR). Affected patients typically present with signs of severe adrenal failure in early infancy and 46,XY genetic males are phenotypic females due to disrupted testicular androgen secretion. The StAR p.Q258X mutation accounts for about 70% of affected alleles in most patients of Japanese and Korean ancestry. However, it is more prevalent (92.3%) in the Korean population. Recently, some patients have been showed that they had late and mild clinical findings. These cases and studies constitute a new entity of 'nonclassic lipoid CAH'. The cholesterol side-chain cleavage enzyme, P450scc (CYP11A1), plays an essential role converting cholesterol to pregnenolone. Although progesterone production from the fetally derived placenta is necessary to maintain a pregnancy to term, some patients with P450scc mutations have recently been reported. P450scc mutations can also cause lipoid CAH and establish a recently recognized human endocrine disorder. PMID:25654062

    The case records of 21 dogs with congenital portosystemic encephalopathy are reviewed. The disorder was most common in Australian cattledogs (blue heelers; 8 cases), Old English sheepdogs (3 cases) and Maltese terriers (3 cases). Extra-hepatic shunts occurred in small breeds, with the exception of 1 cattledog, while intra-hepatic shunts occurred in the medium to large breeds. The most common clinical pathology abnormalities were abnormal ammonia tolerance, mild to moderate increases in plasma alanine aminotransferase or alkaline phosphatase concentrations, decreased total serum protein concentrations, increased fasting ammonia concentrations and ammonium biurate crystalluria. Radiological examination revealed that all the dogs had a small liver. The kidneys were enlarged in 5 of 10 dogs in which kidney size could be estimated. Surgical ligation of an extra-hepatic shunt was successful in 2 of 4 dogs in which it was attempted. Medical management resulted in alleviation of clinical signs in 5 of 8 dogs. The period of successful treatment ranged from a few months to over a year.

    Knowledge of consanguinity is relevant for employees in the Danish national health service, since about 7.5% of the Danish population has another ethnic background than Danish and the majority comes from cultures where consanguineous marriages are not unusual. In the literature it is found that consanguineous couples have a higher risk of having children with congenital malformations. The risk is increased by a factor 2 to 2 1/2. The average risk in Denmark is about 3%. Primarily, the autosomal recessive diseases are expressed in children with consanguineous parents. In order to advise and diagnose it is essential to clarify the consanguinity state. In case of pregnancy with consanguineous parents, we recommend: 1) Counselling to estimate the risk of foetal illness and information about possible examination possibilities. 2) An ultrasound scan at the gestational age of 11-14 weeks in order to measure nuchal translucency and an early malformation scan. 3) An ultrasound scan for malformations at the gestational age of 18-20 weeks. 4) An ultrasound scan especially in order to detect foetal heart malformations at the gestational age of 20-24 weeks.

    Recent advances in and controversies concerning the management of children with congenital valvular aortic stenosis are discussed. In neonates with critical aortic stenosis, improved survival has recently been reported after surgical open valvotomy and balloon valvuloplasty, although it is difficult at this point to compare the results of the two procedures and determine their differential indications. Good results have also been achieved after extended aortic valvuloplasty for recurrent aortic stenosis and/or insufficiency, but the length of follow-up in these patients is still short. The technique first reported in 1991 for bilateral enlargement fo a small annulus permits the insertion of an aortic valve 3-4 sizes larger than the native annulus. It entails no risk of distorting the mitral valve, damaging the conduction system or important branches of the coronary arteries, or resulting in left ventricular dysfunction. The Ross procedure is now widely applied in the West, with reports of early mortality rates of less than 5% and event-free survival rates of 80-90% during follow-up of 4-8 years. Longer follow-up and continued careful evaluation are required to resolve the issue of possible dilatation and subsequent neoaortic valve dysfunction and pulmonary stenosis due to allograft degeneration after pulmonary autograft root replacement in children.

  13. Congenital Diaphragmatic Hernia

    PubMed Central

    2012-01-01

    Congenital Diaphragmatic Hernia (CDH) is defined by the presence of an orifice in the diaphragm, more often left and posterolateral that permits the herniation of abdominal contents into the thorax. The lungs are hypoplastic and have abnormal vessels that cause respiratory insufficiency and persistent pulmonary hypertension with high mortality. About one third of cases have cardiovascular malformations and lesser proportions have skeletal, neural, genitourinary, gastrointestinal or other defects. CDH can be a component of Pallister-Killian, Fryns, Ghersoni-Baruch, WAGR, Denys-Drash, Brachman-De Lange, Donnai-Barrow or Wolf-Hirschhorn syndromes. Some chromosomal anomalies involve CDH as well. The incidence is < 5 in 10,000 live-births. The etiology is unknown although clinical, genetic and experimental evidence points to disturbances in the retinoid-signaling pathway during organogenesis. Antenatal diagnosis is often made and this allows prenatal management (open correction of the hernia in the past and reversible fetoscopic tracheal obstruction nowadays) that may be indicated in cases with severe lung hypoplasia and grim prognosis. Treatment after birth requires all the refinements of critical care including extracorporeal membrane oxygenation prior to surgical correction. The best hospital series report 80% survival but it remains around 50% in population-based studies. Chronic respiratory tract disease, neurodevelopmental problems, neurosensorial hearing loss and gastroesophageal reflux are common problems in survivors. Much more research on several aspects of this severe condition is warranted. PMID:22214468

    Congenital cystic lung lesions are rare. Mainly affects the lower respiratory patishta.i are congenital cystic malformation and adematozna bronchopulmonary sequestration (BPS). The pathogenesis of the occurrence of these malformations is not clear but they have a common clinical course. In most cases, the anomaly is asymptomatic and occurs with infections of the lung during the first year of life. Currently congenital lung lesions were classified into five types and is considered by most authors. The anomaly is due to the abnormal proliferation of terminal bronchioles accompanied by inhibition of alveolar development between 7-17 weeks, obstructed airway dysplasia and metaplasia of normal lung tissue. Early diagnosis is vital in making a medical decision on how to treat CCAM. Associated with abnormalities of the urinary tract, cardiovascular system, gastrointestinal atresia, diaphragmatic hernia skeletal abnormalities. In pregnancies in which prenatal lung lesions weighs registered necessary series of ultrasound examinations to track finding and using the Doppler to assess how the blood supply of the fault. The clinical presentation of malformations is respiratory distress, respiratory infection, and dyspnea. The use of CT and MRA allows better visualization of the pulmonary lesions. With its combination with arteriography and bronchoscopy are used to differentiate CCAM and pulmonary sequestration. We present three cases with lung lesions were born in Neonatologia clinic at the University Hospital of Obstetrics and Gynecology "Maternity" Sofia for the period 2010-2012 three cases CCAMs type 1, operated by 5 meters after birth with a good final outcome without complications in the postoperative period and lack of pulmonary symptoms up to 1 year after birth.

    2012-02-01

    This review defines the concepts of maternal-fetal (congenital) and vertical transmissions (mother-to-child) of pathogens and specifies the human parasites susceptible to be congenitally transferred. It highlights the epidemiological features of this transmission mode for the three main congenital parasitic infections due to Toxoplasma gondii, Trypanosoma cruzi and Plasmodium sp. Information on the possible maternal-fetal routes of transmission, the placental responses to infection and timing of parasite transmission are synthesized and compared. The factors susceptible to be involved in parasite transmission and development of congenital parasitic diseases, such as the parasite genotypes, the maternal co-infections and parasitic load, the immunological features of pregnant women and the capacity of some fetuses/neonates to overcome their immunological immaturity to mount an immune response against the transmitted parasites are also discussed and compared. Analysis of clinical data indicates that parasitic congenital infections are often asymptomatic, whereas symptomatic newborns generally display non-specific symptoms. The long-term consequences of congenital infections are also mentioned, such as the imprinting of neonatal immune system and the possible trans-generational transmission. The detection of infection in pregnant women is mainly based on standard serological or parasitological investigations. Amniocentesis and cordocentesis can be used for the detection of some fetal infections. The neonatal infection can be assessed using parasitological, molecular or immunological methods; the place of PCR in such neonatal diagnosis is discussed. When such laboratory diagnosis is not possible at birth or in the first weeks of life, standard serological investigations can also be performed 8-10 months after birth, to avoid detection of maternal transmitted antibodies. The specific aspects of treatment of T. gondii, T. cruzi and Plasmodium congenital infections are

    Typhoid fever is an enteric infection caused by Salmonella typhi. In Indonesia, typhoid fever is endemic with high incidence of the disease. In daily practice we frequently have patients with bronchial asthma, and it is becoming worse when these patients get typhoid fever. After oral ingestion, Salmonella typhi invades the the intestine mucosa after conducted by microbial binding to epithelial cells, destroying the microfold cells (M cell) then passed through the lamina propria and detected by dendritic cells (DC) which express a variety of pathogen recognition receptors on the surfaces, including Toll-Like Receptor (TLR). expressed on macrophages and on intestinal epithelial cells inducing degradation of IB, and translocation of NF-B (Nuclear Factor-Kappa Beta). This process initiates the induction of pro-inflammatory gene expression profile adhesion molecules, chemokines, adhesion molecules, and other proteins that induce and perpetuate the inflammation in host cells then will induce acute ant intractable attack of bronchial asthma. The role of typhoid fever in bronchial asthma, especially in persons with acute attack of bronchial asthma, is not well understood. In this article, we will discuss the role of typhoid fever in the bronchial asthma patients which may cause bronchial asthma significantly become more severe even triggering the acute and intractable attack of bronchial asthma. This fact makes an important point, to treat completely the typhoid fever in patients with bronchial asthma.

    We report a new-born girl with partial trisomy of 4q28-qter and partial monosomy of 9p24-9ter. Our patient has choanal atresia, hypertelorism, wide nasal bridge, high arched palate, discrete nipples, heart defects, myoclonic seizures and various dysmorphic findings. Standard chromosomal analysis with G-banding with Trypsin-Giemsa revealed 46,XX,der(9)t(4;9)(q28;p24) resulting from the mother's t(4,9) (q28;p24) karyotype. Deletions of the terminal part of 9p and partial trisomy of chromosome 4q are rare chromosomal alterations. To our knowledge, this is the first report of choanal atresia in a patient with a partial trisomy of 4q28-qter and partial monosomy 9p24-9ter combination, which were detected by integrated cytogenetic and genomic analysis.

    Lung transplantation has resulted in dramatic functional improvement in patients with end-stage pulmonary diseases. Among the complications of lung transplantation are dehiscence and stenosis at the site of the bronchial or tracheal anastomosis. In this case report, we describe a single lung transplant recipient in whom partial bronchial dehiscence, followed by exuberant growth of granulation tissue, resulted in obstruction of the bronchial lumen. After mechanical dilation failed to produce lasting relief of bronchial obstruction, a novel approach to this problem was successfully employed: YAG laser phototherapy was used to remove obstructing granulation tissue, followed by application of a preparation derived from autologous blood platelets to promote epithelialization of the bronchial anastomosis. The bronchus remains patent and fully epithelialized six months after therapy.

    Di(2-ethylhexyl) phthalate (DEHP) is a ubiquitous environmental toxicant found in consumer products that causes ovarian toxicity. Antral follicles are the functional ovarian units and must undergo growth, survival from atresia, and proper regulation of steroidogenesis to ovulate and produce hormones. Previous studies have determined that DEHP inhibits antral follicle growth and decreases estradiol levels in vitro; however, the mechanism by which DEHP elicits these effects is unknown. The present study tested the hypothesis that DEHP directly alters regulators of the cell cycle, apoptosis, and steroidogenesis to inhibit antral follicle functionality. Antral follicles from adult CD-1 mice were cultured with vehicle control or DEHP (1–100 μg/ml) for 24–96 h to establish the temporal effects of DEHP on the follicle. Following 24–96 h of culture, antral follicles were subjected to gene expression analysis, and media were subjected to measurements of hormone levels. DEHP increased the mRNA levels of cyclin D2, cyclin dependent kinase 4, cyclin E1, cyclin A2, and cyclin B1 and decreased the levels of cyclin-dependent kinase inhibitor 1A prior to growth inhibition. Additionally, DEHP increased the mRNA levels of BCL2-associated agonist of cell death, BCL2-associated X protein, BCL2-related ovarian killer protein, B-cell leukemia/lymphoma 2, and Bcl2-like 10, leading to an increase in atresia. Further, DEHP decreased the levels of progesterone, androstenedione, and testosterone prior to the decrease in estradiol levels, with decreased mRNA levels of side-chain cleavage, 17α-hydroxylase-17,20-desmolase, 17β-hydroxysteroid dehydrogenase, and aromatase. Collectively, DEHP directly alters antral follicle functionality by inhibiting growth, inducing atresia, and inhibiting steroidogenesis. - Highlights: • DEHP inhibits antral follicle growth by dysregulating cell cycle regulators. • DEHP induces antral follicle atresia by dysregulating apoptosis regulators. • DEHP

    2015-01-01

    Introduction: Vascular complications are very common in pediatric living donor liver transplants. We present our experience in vascular complications in biliary atresia patients undergoing liver transplantation. Materials and Methods: All the patients who have undergone living donor liver transplant for biliary atresia from January 2003 to March 2013 were retrospectively analyzed. P value < 0.05 was considered to be statistically significant. Results: Total 110 patients have undergone living donor liver transplantation for biliary atresia between January 2003 and March 2013. There were 56 males and 54 females. Median age at transplant was 13.5 months. Eleven were primary transplants and 99 were post KASAI procedure. One hundred left lateral, four left lobe, and four right lobe grafts were used. Twenty-two patients developed vascular complications. Twelve patients developed hepatic artery thrombosis. Eleven patients of hepatic artery thrombosis were managed with redo hepatic artery anastomosis and one patient managed with radial artery interposition graft. Five patients developed portal vein stenosis and were managed by portal vein stenting. Five patients developed portal vein thrombosis and portal vein thrombectomy and re-anastomosis were done. One patient developed stenosis at the site of venous anastomosis and was managed by stenting. One patient developed both hepatic artery thrombosis and portal vein thrombosis and eventually succumbed to these complications. Out of five cases who died in this study, two had vascular complications. Graft/recipient weight ratio (GRWR) greater than 2.5 was significantly associated with vascular complications (P = 0.017). Conclusion: Vascular complications are frequently seen in liver transplantation for biliary atresia. Large for size grafts, weight less than 10 kg, age less than 1 year, and prolonged warm ischemia time is significantly associated with vascular complications. PMID:26166981

    Objective Fat soluble vitamin (FSV) deficiency is a well-recognized consequence of cholestatic liver disease and reduced intestinal intraluminal bile acids. We hypothesized that serum bile acids (SBA) would predict biochemical FSV deficiency better than serum total bilirubin level (TB) in infants with biliary atresia. Methods Infants enrolled in the Trial of Corticosteroid Therapy in Infants with Biliary Atresia (START) after hepatoportoenterostomy were the subjects of this investigation. Infants received standardized FSV supplementation and monitoring of TB, SBA and vitamin levels at 1, 3 and 6 months. A logistic regression model was used with the binary indicator variable insufficient/sufficient as the outcome variable. Linear and non-parametric correlations were made between specific vitamin measurement levels and either TB or SBA. Results The degree of correlation for any particular vitamin at a specific time point was higher with TB than SBA (higher for TB in 31 circumstances versus 3 circumstances for SBA). Receiver operating characteristic (ROC) shows that TB performed better than SBA (AUC 0.998 vs. 0.821). Including both TB and SBA did not perform better than TB alone (AUC 0.998). Conclusion We found that TB was a better predictor of FSV deficiency than SBA in infants with biliary atresia. The role of SBA as a surrogate marker of FSV deficiency in other cholestatic liver diseases, such as PFIC, alpha-one antitrypsin deficiency and Alagille syndrome where the pathophysiology is dominated by intrahepatic cholestasis, warrants further study.

    Thoracoscopic repair of esophageal atresia has becoming the gold standard in many centers because it allows a better cosmetic result and avoids the musculoskeletal sequelae of a thoracotomy. Natural orifice translumenal endocopic surgery (NOTES) is a new surgical paradigm, and its human application has already been started in some procedures. In the present study, we explore the feasibility of performing an esophagoesophageal anastomosis using a single transthoracic single port combined with a peroral access in a rabbit model to simulate repair of esophageal atresia by hybrid NOTES in a human newborn. Adult male rabbits (Oryctolagus cuniculus, n=28) were used to perform the surgical protocol. We used a transthoracic telescope with a 3-mm working channel and a flexible endoscope with a 2.2-mm working channel by peroral access. We performed total esophagotomy with peroral scissors followed by an esophagoesophageal anastomosis achieved with a rigid transthoracic scope helped by the peroral operator. Extracorporeal transthoracic knots were performed to complete the anastomosis. The anastomoses were examined in loco and ex loco, after animal sacrifice. We successfully accomplished a complete esophageal anastomosis in all rabbits using a combination of transthoracic and peroral 3-mm instruments. This study provides important insights for a possible translation of hybrid NOTES to human newborns with esophageal atresia. Forward studies to accomplish their feasibility in human newborns will still be necessary.

    INoEA is the International Network of Esophageal Atresia and consists of a broad spectrum of pediatric specialties and patient societies. The working group on long-gap esophageal atresia (LGEA) set out to develop guidelines regarding the definition of LGEA, the best diagnostic and treatment strategies, and highlight the necessity of experience and communication in the management of these challenging patients. Review of the literature and expert discussion concluded that LGEA should be defined as any esophageal atresia (EA) that has no intra-abdominal air, realizing that this defines EA with no distal tracheoesophageal fistula (TEF). LGEA is considerably more complex than EA with distal TEFs and should be referred to a center of expertise. The first choice is to preserve the native esophagus and pursue primary repair, delayed primary anastomosis, or traction/growth techniques to achieve anastomosis. A cervical esophagostomy should be avoided if possible. Only if primary anastomosis is not possible, replacement techniques should be used. Jejunal interposition is proposed as the best option among the major EA centers. In light of the infrequent occurrence of LGEA and the technically demanding techniques involved to achieve esophageal continuity, it is strongly advised to develop regional or national centers of expertise for the management and follow-up of these very complex patients.

    Animal studies suggest that early visual deprivation can cause permanent functional blindness. However, few human data on this issue exist. Given enough time for recovery, can a person gain visual skills after several years of congenital blindness? In India, we recently had an unusual opportunity to work with an individual whose case history sheds light on this question. S.R.D. was born blind, and remained so until age 12. She then underwent surgery for the removal of dense congenital cataracts. We evaluated her performance on an extensive battery of visual tasks 20 years after surgery. We found that although S.R.D.'s acuity is compromised, she is proficient on mid- and high-level visual tasks. These results suggest that the human brain retains an impressive capacity for visual learning well into late childhood. They have implications for current conceptions of cortical plasticity and provide an argument for treating congenital blindness even in older children.

    Congenital nystagmus is a pathologic oculomotor state appearing at about three to four months of age. The precise diagnosis requires detailed clinical examination and electrophysiological findings. This case report presents two male patients with congenital nystagmus examined longitudinally from the age of six months until 17–18 years of age. Clinical and electrophysiological protocols were detailed. The first results showed electronegative electroretinography in the two cases and examination combined with electroretinographic findings helped us to make the diagnosis of Congenital Night Stationary Blindness (CSNB). This diagnosis was confirmed by genetic studies. CSNB is interesting to study because through electrophysiological findings, it enables a better understanding of the physiology of neural transmission in the outer part of the retina. PMID:21573087

    Carbon nanotubes are being actively introduced in electronics, computer science, aerospace, and other industries. Thus, the urgent need for toxicological studies on CNTs is mounting. In this study, we investigated the alterations in cellular response with morphological changes induced by single-walled carbon nanotubes (SWCNTs) in BEAS-2B cells, a human bronchial epithelial cell line. At 24h after exposure, SWCNTs rapidly decreased ATP production and cell viability as well a slight increase in the number of cells in the subG1 and G1 phases. In addition, SWCNTs increased the expression of superoxide dismutase (SOD)-1, but not SOD-2, and the number of cells generating ROS. The concentration of Cu and Zn ions also increased in a dose-dependent manner in cells exposed to SWCNTs. SWCNTs significantly enhanced the release of nitric oxide, interleukin (IL)-6, and IL-8 and up-regulated the expression of chemokine- and cytokine-related genes. Furthermore, the levels of autophagy-related genes, especially the DRAM1 gene, and the autophagosome formation-related proteins, were clearly up-regulated together with an increase of autophagosome-like vacuoles. Based on these results, we suggest that SWCNTs induce autophagic cell death through mitochondrial dysfunction and cytosolic damage in human bronchial epithelial cells.

    An optical fiber based low coherence interferometer for measuring the Epithelium thickness of Bronchial tissue, for early diagnosis of Carcinoma in situ, is presented. Previous simulation of laser induced fluorescence using an electromagnetic scattering model has extracted the relative permittivity value for the Submucosa and Epithelium layers indicating a difference of up to 0.14. The optical system presented here uses a low coherence source operating at 840 nm with a bandwidth of 30 nm, coupled into single mode optical fiber. A Fizeau cavity is formed between the fiber end and the tissue under investigation. A remote processing interferometer is used to monitor changes in permittivity between the different tissue layers. An initial experiment has demonstrated a sensitivity measurement of 40 dB for a permittivity difference measurement of 0.61. Preliminary results have shown that the discontinuity between the Bronchial Epithelium layer and its surrounding medium can be identified allowing the thickness of the Epithelium layer to be measured to an accuracy of 20 micrometers . Since interferometric noise contributions are only significant within the processing interferometer, the fiber optic Fizeau interferometer technique is a strong candidate for the development of an endoscope for the early detection of cancer within Gastrointestinal and Respiratory tracts.

    We used the Impulse Oscillometric System (IOS) to gain information concerning the distribution of hyper-reactivity along the bronchial tree during methacholine challenge test (MCT). 37 subjects underwent MCT until reaching the provocative dose (PD20). At each dose, we estimated respiratory resistance at 5 and 20Hz (R5, R20), and reactance at 5Hz (X5). In non-responsive subjects (N=14) no changes in R5, R20, and X5 were observed during MCT. In responsive subjects, a wide spectrum of responses was found concerning frequency dependence and PD20. We describe two phenotypes representing the extremes of response. For PD20>400μg (N=13), MCT caused equal changes of resistance/reactance on varying oscillation frequencies, suggesting a homogeneous bronchoconstriction along the bronchial tree. For PD20<200μg (N=10), a remarkable frequency dependence was observed, with increase in R5, no change in R20, and decrease in X5, suggesting hyper-responsiveness of the distal airways paralleled by a change in visco-elastic properties of lung parenchyma.

    In the period between 1982-1986, 2132 neoplasms were registered in the Zadar Medical Center, out of them 164 (7.7%) were primary bronchial carcinomas of which 138 (84.1%) were morphologically verified. The difference between the number of the registered and verified bronchial carcinomas is due to the difference in the registration criteria. The annual average incidence rate of the verified carcinomas was about 30 which is lower than in the Zagreb area and Croatia as a whole. The average number of cases diagnosed in other institutions was about 20 percent. An analysis by sex revealed a prevalence among males aged 55-75. Morphologically, the most common type of carcinoma was planocellular, followed by anaplastic, small cell carcinoma and adenocarcinoma. The greatest majority of the positive findings was obtained by bronchoscopy and sputum examination. The average number of sputa obtained per patient was 3.5; 63 percent of these were adequate and 40 percent of them were positive. In 86% of cases the diagnosis was established from the first three sputa. The most frequently used bronchoscopic method of material obtained was aspiration and the best diagnostic results were obtained by puncture biopsy and excision. The high percentage of positive results obtained by transtracheal biopsy justifies its use.

    Broncho-pleural fistula is a difficult clinical problem without a simple solution. Laser-assisted solder techniques potentially offer a means to precisely fix tissue glues into the fistulae through a bronchoscopic approach. Using a canine model, secondary bronchi were sealed with cryoprecipitate made from solvent/detergent treated plasma (treated to inactivate membrane enveloped virus) mixed with indocyanine green (absorption 805 nm). Diode laser energy (emission 808 nm, 7.3 W/cm2) was applied to the solder until desiccation was observed. Leakage pressures ranged between 18 - 86 mmHg with a mean of 46 +/- 24 mmHg. Laser-assisted solder techniques provide a reliably strong seal over leaking bronchial stumps and use of dye enhancement prevents undesired collateral thermal injury to surrounding bronchial tissue. Solvent/detergent plasma, prepared by methods shown to inactivate large quantities of HIV, HBV, and HCV, is an effective source of cyroprecipitate and should allow widespread use of pooled human material in a clinical setting.

    This review focuses on the methods available for measuring reversible airways obstruction, bronchial hyperresponsiveness (BHR) and inflammation as hallmarks of asthma, and their role in monitoring children with asthma. Persistent bronchial obstruction may occur in asymptomatic children and is considered a risk factor for severe asthma episodes and is associated with poor asthma outcome. Annual measurement of forced expiratory volume in 1 s using office based spirometry is considered useful. Other lung function measurements including the assessment of BHR may be reserved for children with possible exercise limitations, poor symptom perception and those not responding to their current treatment or with atypical asthma symptoms, and performed on a higher specialty level. To date, for most methods of measuring lung function there are no proper randomised controlled or large longitudinal studies available to establish their role in asthma management in children. Noninvasive biomarkers for monitoring inflammation in children are available, for example the measurement of exhaled nitric oxide fraction, and the assessment of induced sputum cytology or inflammatory mediators in the exhaled breath condensate. However, their role and usefulness in routine clinical practice to monitor and guide therapy remains unclear, and therefore, their use should be reserved for selected cases.

    Leber's congenital amaurosis (LCA) is a clinically and genetically heterogeneous disorder characterized by severe loss of vision at birth. It accounts for 10-18% of cases of congenital blindness. Some patients exhibit only blindness of retinal origin whereas others show evidence of a multi-systemic involvement. We review the literature relating to this severe disorder, highlighting unresolved questions, in particular the nature of the association of LCA with mental retardation and with systemic findings and syndromic pictures. In recent years, genetic advances in the diagnosis of LCA have opened up new horizons, also from a therapeutic point of view. A better understanding of this pathology would be valuable for paediatric neurologists.

    The Ilizarov device and distraction osteogenesis method became very useful in correction and elongation of forearm defects. Two cases of forearm elongation with congenital transverse defect are described. The construction of the device is provided. During follow-up examination, 2 and 7 years after the treatment, good clinical results were achieved in both patients with the use of upper limb prosthesis employing the patient's own elbow joint. Presented application of the Ilizarov method can significantly improve possibilities for the use of prosthesis in patients with congenital upper limb defects and result in better cosmetic and functional outcome.

    Not being satisfied with the present-day diagnosis of Leber's congenital amaurosis, the original papers written by Leber were studied. It gradually became clear that what Leber had in mind with congenital amaurosis is roughly the same as what we know as neuronal ceroid lipofuscinosis. The present diagnosis of Leber's congenital amaurosis is not a clinical syndrome but an aspecific symptom complex.

    A 10-day-old male Holstein dairy calf with orthopaedic abnormalities was unable to stand but was alert with a suckle reflex. At necropsy, the calf showed multiple defects, including partial agenesis of the left rib plate, deformed left scapula, shortened left humerus, agenesis of the left kidney, atresia ani and scoliosis. The cause of these anomalies could not be determined. This report is the first to describe partial agenesis of ribs in a calf.

    Congenital absence of the pericardium is a rare cardiac malformation and is most often asymptomatic. It is usually discovered as an incidental finding. Physical examination, chest radiography, and electrocardiogram are often unremarkable. Echocardiography provides valuable information, and sometimes computed tomography or magnetic resonance imaging is needed for subsequent confirmation. PMID:24753808

    Bronchial blood flow was determined in five adult anaesthetised sheep by the video dilution technique. This is a new fluoroscopic technique for measuring blood flow that requires only arterial catheterisation. Catheters were placed into the broncho-oesophageal artery and ascending aorta from the femoral arteries for contrast injections and subsequent videotape recording. The technique yields bronchial blood flow as a percentage of cardiac output. The average bronchial artery blood flow was 0.6% (SD 0.20%) of cardiac output. In one sheep histamine (90 micrograms) injected directly into the bronchial artery increased bronchial blood flow by a factor of 6 and histamine (90 micrograms) plus methacholine (4.5 micrograms) augmented flow by a factor of 7.5 while leaving cardiac output unchanged. This study confirms the high degree of reactivity of the bronchial circulation and demonstrates the feasibility of using the video dilution technique to investigate the determinants of total bronchial artery blood flow in a stable animal model avoiding thoracotomy.

    This investigation was aimed at the complex evaluation of the reactivity mechanisms of bronchial smooth muscle tissue (SMT) in experimental bronchial spasm. Morphometric, cytospectrophotometric and electron microscopical analysis demonstrated the presence of three types of smooth muscle cells (SMC) within the bronchial SMT (small, medium, large), that differed in their linear and metabolic parameters. The findings of this study indicate that under the conditions of experimental bronchial spasm development, the ratios of SMC in bronchial SMT are changed with the increase in proportion of small SMC and the elimination of large SMC. In the dynamics of experimental bronchial spasm development, the activation of cytoplasmic synthesis as well as of DNA synthesis was detected mainly in group of small SMC. The reactive-dystrophic changes were marked at the subcellular level, that were most often identified in large SMC resulting in their elimination from population in the dynamics of an experiment. The data obtained suggest that one of the important mechanisms of airway SMT adaptation to the bronchial spasm development is a dynamic reorganization of SMC population.

    Studies have shown that eosinophils are closely related to pathogenesis of bronchial asthma. Eosinophils release eosinophil cationic protein (ECP), which plays an important role in infection and allergic reactions. Serum ECP mRNA expression in children with bronchial asthma has not been adequately investigated. We analyzed serum ECP mRNA expression in 63 children with bronchial asthma and 21 healthy children by using reverse-transcriptase polymerase chain reaction to understand the role of ECP in children with bronchial asthma. The children with bronchial asthma were segregated into acute-phase and stable-phase groups, based on the severity of the illness. Serum ECP mRNA expression in children with bronchial asthma (0.375 ± 0.04) was significantly higher than that in healthy controls (0.20 ± 0.02; P < 0.05). Additionally, children in the acute-phase group showed higher ECP mRNA expression level (0.44 ± 0.06) than those in the stable-phase (0.31 ± 0.03) and healthy control groups (0.20 ± 0.02; P < 0.05), while the level in the stable-phase (0.31 ± 0.03) was markedly higher than that in the healthy control group (0.20 ± 0.02; P < 0.05). Detection of serum ECP mRNA expression level has possible applications in the diagnosis and treatment of children with bronchial asthma.

    AIM To compare the outcome between patients with jejunoileal atresia (JIA) associated with cystic meconium peritonitis (CMP) and patients with isolated JIA (JIA without CMP). METHODS A retrospective study was conducted for all neonates with JIA operated in our institute from January 2005 to January 2016. Demographics including the gestation age, sex, birth weight, age at operation, the presence of associated syndrome was recorded. Clinical outcome including the type of operation performed, operative time, the need for reoperation and mortality were studied. The demographics and the outcome between the 2 groups were compared. RESULTS During the study period, 53 neonates had JIA underwent operation in our institute. Seventeen neonates (32%) were associated with CMP. There was no statistical difference on the demographics in the two groups. Patients with CMP had earlier operation than patients with isolated JIA (mean 1.4 d vs 3 d, P = 0.038). Primary anastomosis was performed in 16 patients (94%) with CMP and 30 patients (83%) with isolated JIA (P = 0.269). Patients with CMP had longer operation (mean 190 min vs 154 min, P = 0.004). There were no statistical difference the need for reoperation (3 vs 6, P = 0.606) and mortality (2 vs 1, P = 0.269) between the two groups. CONCLUSION Primary intestinal anastomosis can be performed in 94% of patients with JIA associated with CMP. Although patients with CMP had longer operative time, the mortality and reoperation rates were low and were comparable to patients with isolated JIA. PMID:28224094

    The histopathological effects of Taenia crassiceps infection or T. crassiceps metacestode factor inoculation on the mouse ovary were determined using six female mice in three groups: infected mice, mice inoculated with the metacestode factor and control mice. The control group was subcutaneously inoculated with healthy peritoneal fluid. The infected group was intraperitoneally inoculated with 40 T. crassiceps metacestodes, and the metacestode factor group was subcutaneously inoculated with T. crassiceps metacestode factor (MF). Light and electron microscopy and TUNEL (terminal deoxynucleotidyl transferase (TdT)-mediated dUTP nick end labelling) assays revealed a significant increase in ovarian follicular atresia (predominantly in antral/preovulatory stages of development), oocyte degeneration (P< 0.05), and a decrease in the amount of corpus luteum in follicles of mice infected and inoculated with MF compared with the control group. Significant abnormalities of the granulosa cells and oocytes of the primordial, primary and secondary ovarian follicles occurred in both treated mouse groups (P< 0.05) compared with no degeneration in the control group. These pathological changes in female mice either infected with T. crassiceps metacestodes or inoculated with T. crassiceps MF may have consequences for ovulation and fertility.

    Objective. Duodenal atresia (DA) routinely has been corrected by laparotomy and duodenoduodenostomy with excellent long-term results. We revisited the patients with DA treated in the last 12 years (2004–2016) comparing the open and the minimally invasive surgical (MIS) approach. Methods. We divided our cohort of patients into two groups. Group 1 included 10 patients with CDO (2004–09) treated with open procedure: 5, DA; 3, duodenal web; 2, extrinsic obstruction. Three presented with Down's syndrome while 3 presented with concomitant malformations. Group 2 included 8 patients (2009–16): 1, web; 5, DA; 2, extrinsic obstruction. Seven were treated by MIS; 1 was treated by Endoscopy. Three presented with Down's syndrome; 3 presented with concomitant malformations. Results. Average operating time was 120 minutes in Group 1 and 190 minutes in Group 2. In MIS Group the visualization was excellent. We recorded no intraoperative complications, conversions, or anastomotic leakage. Feedings started on 3–7 postoperative days. Follow-up showed no evidence of stricture or obstruction. In Group 1 feedings started within 10–22 days and we have 1 postoperative obstruction. Conclusions. Laparoscopic repair of DA is one of the most challenging procedures among pediatric laparoscopic procedures. These patients had a shorter length of hospitalization and more rapid advancement to full feeding compared to patients undergoing the open approach. Laparoscopic repair of DA could be the preferred technique, safe, and efficacious, in the hands of experienced surgeons. PMID:28326320

    Early detection is the most effective way to improve the clinical outcome of biliary atresia (BA). Emerging metabolomics provides a powerful platform for discovering novel biomarkers and biochemical pathways to improve early diagnosis. The aim of this study is to find the potential biomarkers to distinguish BA from neonatal hepatitis syndrome (NHS) by using a metabolomics method. We comprehensively analyzed the serum metabolites in a total of 124 blood samples from patients with BA or neonatal hepatitis syndrome (NHS) and from normal individuals using advanced metabolomic approaches, and found that the levels of glutarylcarnitine (C5DC) significantly increased in the BA group while the levels of threonine (Thr) significantly rose in the NHS group comparing with the other groups. The levels of glutamic acid (Glu) in the BA group were significantly elevated compared to those in the NHS group, but still lower than the hyperbilirubinemia and normal controls. The levels of propionyl carnitine (C3), isovaleryl carnitine (C5) and glutamine (Gln) were reduced in the BA group compared to those in the NHS group, but still higher than the hyperbilirubinemia and normal controls. This study demonstrates the possibility of metabolomics as non-invasive biomarkers for the early detection of BA and also provides new insight into pathophysiologic mechanisms for BA. PMID:24416443

    AIM To investigate serum urokinase-type plasminogen activator receptor (uPAR) and liver stiffness in biliary atresia (BA) and examine the correlation of circulating uPAR, liver stiffness, and clinical outcomes in postoperative BA children. METHODS Eighty-five postKasai BA children and 24 control subjects were registered. Circulating uPAR was measured using enzyme-linked immunosorbent essay. Liver stiffness was analyzed using transient elastography. RESULTS BA children had significantly greater circulating uPAR and liver stiffness scores than control subjects (P < 0.001). Circulating uPAR and liver stiffness were substantially higher in jaundiced BA children than non-jaundiced BA children (P < 0.001). In addition, circulating uPAR was positively associated with serum aspartate aminotransferase (r = 0.507, P < 0.001), alanine aminotransferase (r = 0.364, P < 0.001), total bilirubin (r = 0.559, P < 0.001), alkaline phosphatase (r = 0.325, P < 0.001), and liver stiffness scores (r = 0.508, P < 0.001). CONCLUSION Circulating uPAR and liver stiffness values were greater in BA children than healthy controls. The increased circulating uPAR was associated with liver dysfunction in BA. As a consequence, serum uPAR and liver stiffness may be used as noninvasive biomarkers indicating the progression of liver fibrosis in postKasai BA. PMID:27957246

    INTRODUCTION: Biliary atresia, a common indication for liver transplantation, can be associated with situs inversus. Our experience with liver transplantation in children (n = 6) was reviewed retrospectively. PATIENTS AND METHODS: Preoperative duplex sonography, computerized tomography, and visceral angiography were obtained. Vascular anomalies identified included preduodenal portal vein (6/6), interrupted inferior vena cava (5/6), and aberrant hepatic artery (4/6). RESULTS: The liver graft was placed in a midline position. Venous continuity was achieved by donor suprahepatic inferior vena cava to recipient hepatic cloaca and direct end-to-end portal anastomosis. The donor infrahepatic inferior vena cava was oversewn. Arterial continuity was restored using either a direct branch-patch anastomosis (3/6) or a supraceliac aortic interposition graft (3/6). In retrospect, preoperative diagnostic work-up was noncontributory and outcome was not complicated by pre-existing situs inversus. CONCLUSION: Situs inversus in liver recipients requires operative technical modifications, but does not change outcome. Furthermore, extensive preoperative work-up should be avoided. PMID:7618968

    This report describes a 1-yr-old boy with biliary atresia (BA) and polysplenia syndrome (PS) who underwent successful living-related liver transplantation (LTx). At the time of initial hepatic portoenterostomy, he was noticed to have a preduodenal portal vein (PV), non-rotation of the intestine, and polysplenia. Because he did not achieve good bile excretion, he underwent a living-related LTx (using a left lateral segment from his mother) at the age of 14 months. Evaluation of the vascular anatomy was made by angiography, magnetic resonance imaging (MRI), computerized tomography (CT), and Doppler ultrasound. The PV was stenotic from the confluence of the superior mesenteric vein (SMV) and splenic vein (SpV) to the hepatic hilum. The retrohepatic inferior vena cava (IVC) was deficient cranially to the renal vein and was connected to the azygous vein. The supra-hepatic IVC was detected below the diaphragm and was connected to three hepatic veins. The common hepatic artery (HA) originated from the superior mesenteric artery. At LTx, the PV was dissected to the level of confluence of the SMV and the SpV, from which the venous graft was interposed using the donor's ovarian vein. Three hepatic veins were plastied into one orifice, which was anastomosed to the graft's hepatic vein under the diaphragm. The graft vascularity and function has been good for 1 yr after LTx. In the present case, sufficient pre-LTx evaluation of vascular anomalies seemed to help performance of the successful LTx.

    Biliary atresia (BA), the most common reason for orthotopic liver transplantation (OLT) in children, is often accompanied by unique and challenging anatomical variations. This study examines the effect of surgical-specific issues related to the presence of complex vascular anatomic variants on the outcome of OLT for BA. The study group comprised 944 patients who were enrolled in the Studies of Pediatric Liver Transplantation (SPLIT) registry and underwent OLT for BA over an 11-year period. 63 (6.7%) patients met the study definition of complex vascular anomalies (CVA). Patient survival, but not graft survival, was significantly lower in the CVA group, (83 vs. 93 % at 1-year post-OLT). The CVA group had a significantly higher incidence of all reoperations, total biliary tract complications, biliary leaks and bowel perforation. The most frequent cause of death was infection, and death from bacterial infection was more common in the CVA group. Pretransplant portal vein thrombosis and a preduodenal portal vein were significant predictors of patient survival but not graft survival. This study demonstrates that surgical and technical factors have an effect on the outcome of BA patients undergoing OLT. However, OLT in these complex patients is technically achievable with an acceptable patient and graft survival.

    A male infant with the rare lesion of unguarded tricuspid orifice in the setting of pulmonary valve atresia, intact ventricular septum, and a hypoplastic right ventricle is described. The patient presented with cyanosis at 1 day old; transcutaneous oxygen saturations were between 20% and 30% in room air, and 60% in 100% inspired oxygen. Pre-excitation was found incidentally on the ECG and the potential for rapid antegrade conduction of atrial tachyarrhythmias, after eventual extended palliation with the Fontan procedure, was demonstrated at electrophysiological study. By 11 months old the patient was becoming increasingly cyanosed and interim palliation with a bidirectional cavopulmonary shunt was proposed. Successful radiofrequency ablation of the accessory pathway was performed before bidirectional cavopulmonary shunt, which would have prevented access to the heart via the superior vena cava. Difficulty with femoral venous access because of previous occlusion of a femoral vein was overcome by the use of 2 F pacing electrodes and a 5 F ablation catheter.

    While unilateral pulmonary venous atresia (UPVA) most commonly presents as an extremely rare late embryological defect resulting in complete occlusion or absence of the PV pathway, it may also be an acquired pathology. We present a 3-year-old boy who presented with mild respiratory distress. Neonatal echocardiographic investigations revealed normal mediastinal anatomy and pulmonary vasculature with a bicuspid aortic valve. However, follow-up Doppler investigation revealed a pulmonary artery size difference with minimal forward flow and reverse flow during diastole. Absence of the left pulmonary veins and the presence of collaterals draining to the innominate vein confirmed the diagnosis of acquired UPVA. Our case represents the first case of acquired UPVA in conjunction with a normally functioning bicuspid aortic valve. The Doppler flow patterns discussed might be of significant interest to pediatricians, cardiologists and imaging specialists. These findings suggest that acquired UPVA should be considered in the differential diagnosis of such patients when radiographic and echocardiographic findings may rule out other more common diagnoses. While the management of such a condition remains unclear and conservative management was agreed upon for our patient, the vulnerability of such cases warrants timely diagnosis and routine monitoring.

    A case of extrahepatic biliary atresia presenting with an acute respiratory episode and rapid deterioration, 10 years after a successful portoenterostomy and a very active life, was the setting of unsuspected severe pulmonary arterial hypertension leading to sudden death. The pulmonary arteries showed widespread plexiform lesions, thickening of the muscular media, and subendothelial proliferation. Occasionally, eccentric arterial obstructive lesions and fibrinous thrombi were observed. There was marked reduction of preacinar arterioles with a consequent increase in the alveolar/arterial ratio. The pulmonary veins showed arterialization of their walls. There was marked hypertrophy of myocardial fibres in the right ventricle together with foci of myocardial degeneration and fibrosis. Areas of endocardial thickening were observed in both ventricles. The absence of clinical indicators of pulmonary arterial hypertension at any but the terminal stages of the disease precluded any form of conservative management. Lung-heart and presumably liver transplantation might have been the only option. Prospective assessment of pulmonary function and haemodynamic studies should be considered in cirrhotic patients with portal hypertension.

    Biliary atresia (BA) is a progressive fibro-inflammatory disorder that is the leading indication for liver transplantation in children. Although there is evidence implicating genetic, infectious, environmental, and inflammatory causes, the etiology of BA remains unknown. We have recently reported that cholangiocytes from BA patients showed decreased DNA methylation relative to disease- and non-disease controls, supporting a potential role for DNA hypomethylation in BA etiopathogenesis. In the current study, we examined the methylation status of specific genes in human BA livers using methylation microarray technology. We found global DNA hypomethylation in BA samples as compared to disease- and non-disease controls at specific genetic loci. Hedgehog pathway members, SHH and GLI2, known to be upregulated in BA, were both hypomethylated, validating this approach as an investigative tool. Another region near the PDGFA locus was the most significantly hypomethylated in BA, suggesting potential aberrant expression. Validation assays confirmed increased transcriptional and protein expression of PDGFA in BA livers. We also show that PDGF-A protein is specifically localized to cholangiocytes in human liver samples. Injection of PDGF-AA protein dimer into zebrafish larvae caused biliary developmental and functional defects. In addition, activation of the Hedgehog pathway caused increased expression of PDGF-A in zebrafish larvae, providing a previously unrecognized link between PDGF and the Hedgehog pathway. Our findings implicate DNA hypomethylation as a specific factor in mediating overexpression of genes associated with BA and identify PDGF as a new candidate in BA pathogenesis. PMID:27010479

    Mono-2-ethyhexyl phthalate (MEHP) is a metabolite of a plasticizer found in many consumer products. MEHP inhibits mouse ovarian follicle growth by reducing 17β-estradiol (E2) production. Yet, whether MEHP causes follicle death (atresia) is unclear. We hypothesized that MEHP causes atresia by altering apoptosis gene expression, and that E2 co-treatment blocks these effects. Follicles were exposed to MEHP (0.36-36μM)±E2 for 48-96h to determine the effect of MEHP±E2 on atresia and gene expression. MEHP increased atresia, but this effect was blocked by co-treatment with E2. MEHP increased the expression of the pro-apoptotic gene Aifm1, but decreased that of the pro-apoptotic gene Bok and the anti-apoptotic gene Bcl2l10. E2 interfered with MEHP-induced changes in Aifm1 and Bcl2l10. Our findings suggest that decreased E2 levels are required for MEHP-induced follicle atresia and that Aifm1, Bok, and Bcl2l10 are involved in this process.

    Mono-2-ethyhexyl phthalate (MEHP) is a metabolite of a plasticizer found in many consumer products. MEHP inhibits mouse ovarian follicle growth by reducing 17β-estradiol (E2) production. Yet, whether MEHP causes follicle death (atresia) is unclear. We hypothesized that MEHP causes atresia by altering apoptosis gene expression, and that E2 co-treatment blocks these effects. Follicles were exposed to MEHP (0.36–36 µM) ± E2 for 48–96h to determine the effect of MEHP ± E2 on atresia and gene expression. MEHP increased atresia, but this effect was blocked by co-treatment with E2. MEHP increased the expression of the pro-apoptotic gene Aifm1, but decreased that of the pro-apoptotic gene Bok and the anti-apoptotic gene Bcl2l10. E2 interfered with MEHP-induced changes in Aifm1 and Bcl2l10. Our findings suggest that decreased E2 levels are required for MEHP-induced follicle atresia and that Aifm1, Bok, and Bcl2l10 are involved in this process. PMID:24412242

    Complications of bronchial artery embolization (BAE) are uncommon. A 37-year-old patient with pulmonary tuberculosis received bronchial artery embolization because of severe hemoptysis. The bilateral bronchial arteries and left internal mammary artery were embolized using a gelatin sponge, and the patient exhibited occipital blindness and ataxia after the second BAE. The dissolvable gelatin sponge possibly entered the posterior circulation, resulting in the multiple infarctions in the bilateral occipital lobes and cerebellum. Because of the bad prognosis and the difficulty for curability, this kind of complication should be recognized in a timely manner and carefully avoided by the interventional radiologists carrying out the BAE.

    Various dates on amoxicillin (resorption, distribution, elimination, tissue passage, urinary excretion) are presented. The bacterial spectrum is more fully discussed. Amoxicillin is compared with ampicillin. Dosage and therapeutical results are presented. Within repeated bronchoscopic examinations necessary on account of bronchopulmonary affections determination of germs were done in 88 children. At the same time examination of ampicillin levels in bronchial secretions were performed after amoxicillin therapy with different high doses (3 x 125 mg to 3 x 750 mg) for 7 days. It could be shown that good antibiotic levels could be found in secretion specimens above all obtained 2 to 4 hours after the last amoxicillin administration. They could be found too, if there did not exist any purulent secretion or stronger inflammation. There are relations between the amount of dosage, the level in secretion as well as the influence on germs.

    The authors review efficiency of various programs of kinesi and hydrokinesitherapy of children with atopic bronchial asthma (BA). Efficiency of the treatment was assessed by quality of life using the questionnaire by A. West, D. French "Childhood asthma questionnaire" (adapted for Russia by V. I. Petrov et al). Monitoring of the activity of allergic inflammation of the upper respiratory tracts was performed by examination of the nasal lavage fluid for nitric oxide metabolites, of the lower respiratory tracts--by the metabolites in the condensate of the expired air. It is shown that hydrokinesitherapy raises BA children's quality of life and declines inflammation activity leading to reduction of the number of BA exacerbations and hospitalizations. The above criteria of the treatment efficacy proved sensitive.

    2017-01-01

    Tracheal and Bronchial injuries are potentially life threatening complications which require urgent diagnosis and therapeutic intervention. They typically occur in association with blunt and penetrating chest trauma although they are increasingly being encountered in patients following endobronchial intervention and percutaneous tracheostomy insertion. Their precise incidence is unknown. Presenting features include dyspnoea, stridor, respiratory and haemodynamic compromise, haemoptysis, surgical emphysema, pneumothorax and persistent significant airleak. There may be other additional injuries to consider in trauma patients with large airway injury. Familiarity with the diagnosis and management of large airway injuries is important for medical teams engaged in emergency medicine, thoracic surgery and medicine, anaesthesia and intensive care. Although early surgical intervention is the mainstay of treatment, endobronchial manoeuvres to seal defects are receiving increasing attention particularly for patients with medical co-morbidities which may contraindicate formal surgery or transfer or where local surgical expertise is not available.

    Men with and men without a history of peptic ulcers were compared using respiratory symptoms and spirographic measurements taken from data recorded in an epidemiologic study. Among the 1,049 men examined, 7% reported a history of peptic ulcer. A clear relationship appeared between bronchial hypersecretion and peptic ulcers. It persisted after adjustment for age, smoking habits, social class, and country of origin. Men with ulcers inhaled tobacco smoke more often. Ulcers, smoking, and chronic phlegm were independently related to a lower body build index. It seems that the relationship between smoking and ulcers was greater among men with chronic phlegm, and it is postulated that peptic ulcers and "chronic bronchitis" might be related to a "common secretory disorder." After adjustment for age, men with a history of peptic ulcers had, not a lower FEV1, but a higher vital capacity. A slightly lower FEV1/VC ratio cannot in such cases be considered as an index of chronic airflow limitation.

    Background: A rare case of intra-bronchial migration of peritoneal catheter of lumboperitoneal (LP) shunt was treated under the bronchoscopic and fluoroscopic observation. Case Description: A 71-year-old man, who underwent LP shunt installation due to idiopathic normal pressure hydrocephalus a year before, presented with history of high fever and sputum production. Roentgenography and computed tomography of the chest revealed migration of distal end of the peritoneal catheter into the left main bronchus. Migrated catheter was gently extracted through the abdominal wound incision under the bronchoscopic and fluoroscopic observation. Contrast material infused into the catheter did not spread into the pleural cavity. The patient was free of the symptoms within 2 postoperative weeks. Moreover, he underwent the ventriculo-peritoneal shunt surgery 1-month later. Conclusion: This is the first case of the migration of peritoneal catheter of LP shunt into the main bronchus.

    1995-10-01

    Bacterial bronchial infection is a frequent cause of COPD exacerbation but not its only aetiology. Increased purulent expectorant appears to be its best indicator rather than fever, non-productive cough or dyspnoea. The clinician must try to recognize this condition rather than systematically prescribe empirical antibiotics. Haemophilus influenzae, Streptococcus pneumoniae and Moraxella catarrhalis are the major pathogens. Although atypical bacteria are not frequent, Chlamydia pneumoniae could play significant role. During the last years, new antibiotics, much more expensive than other regimens, are widely prescribed, often without a rational approach. In patients not already on antibiotics, sputum Gram stain is useful for deciding which patient should be treated and what would be the best anti-biotic. When it is not available, the chosen antibiotic must be at least active against three major pathogens according to the local susceptibility patterns. In patients not responding to the initial treatment, the consideration of its potential spectrum holes is then more useful than sputum examination.

  14. The use of fish oil in bronchial asthma.

    A fish-oil enriched diet has potential in modulating the humoral and inflammatory components of the allergic response by inhibiting the generation of pro-inflammatory mediators derived from arachidonic acid and by reducing the production of PAF-acether. In addition, EPA suppresses the responses of target cells and tissues. Studies in bronchial asthma confirm the anti-inflammatory potential of a fish-oil enriched diet. Dietary supplementation with EPA in subjects with asthma led to changes in leukocyte mediator generation and chemotactic responses. There was also a significant attenuation of the late asthmatic response to inhaled antigen. Further studies are needed to determine the full potential of such diets in effecting changes in the clinical aspects of allergic disease.

    Angiolipoma is a rare benign tumor that most commonly occurs in the extremities and trunk. Angiolipomas originating in the bronchial tree are extremely rare. To the best of our knowledge, only one such case, confined to the bronchus intermedius, has been reported to date. The present study describes the case of an asymptomatic 74-year-old man with a yellowish round mass incidentally discovered at the orifice of the right lower bronchus during a routine health check. The tumor originated from the membranous part of the right inferior bronchus. Using a high-frequency electric snare and argon plasma coagulation under general anesthesia, successful bronchoscopic resection of the tumor was performed. At 15 months after the surgery, the patient remained recurrence- and symptom-free. PMID:28101361

    Folpet, a widely used dicarboximide fungicide, has been detected in the ambient air of several vine-growing regions of France. It is present in particle form in the environment; however, no study exploring its potential health impact on airways and the respiratory system has been published. Here, the biological effect of these particles was investigated in vitro on human bronchial epithelial cells (16HBE14o-). To be close to the real-life conditions of exposure, Folpan 80WG, a commercial form of folpet, was tested. Folpan 80WG particles showed dose- and time-dependent cytotoxic effects on 16HBE14o- cells. This effect was compared to that produced by technical-grade folpet and both were found to induce a toxicity with similar IC(50) values after 24h of exposure. After 4h and at least until 48h of exposure, the IC(50) values of Folpan 80WG particles were between 2.4 and 2.8 microg/cm(2). Investigation of the cytotoxicity found that Folpan 80WG particles at 1.85 microg/cm(2) induced an increase in ROS production from the first hour of exposure. Evidence that oxidative processes occur in folpet-exposed cells was confirmed by the presence of membrane lipid peroxidation. Furthermore, early apoptosis and late apoptosis/necrosis were both present after the first hour of exposure. These findings indicate that exposure to Folpan 80WG particles result in a rapid cytotoxic effect on human bronchial epithelial cells in vitro that could be in part explained by oxidative stress, characterised by membrane lipid peroxidation and ROS production.

    The course of chronic obstructive pulmonary disease (COPD) is frequently aggravated by exacerbations, and changes in the composition and activity of the microbiome may be implicated in their appearance. The aim of this study was to analyse the composition and the gene content of the microbial community in bronchial secretions of COPD patients in both stability and exacerbation. Taxonomic data were obtained by 16S rRNA gene amplification and pyrosequencing, and metabolic information through shotgun metagenomics, using the Metagenomics RAST server (MG-RAST), and the PICRUSt (Phylogenetic Investigation of Communities by Reconstruction of Unobserved States) programme, which predict metagenomes from 16S data. Eight severe COPD patients provided good quality sputum samples, and no significant differences in the relative abundance of any phyla and genera were found between stability and exacerbation. Bacterial biodiversity (Chao1 and Shannon indexes) did not show statistical differences and beta-diversity analysis (Bray-Curtis dissimilarity index) showed a similar microbial composition in the two clinical situations. Four functional categories showed statistically significant differences with MG-RAST at KEGG level 2: in exacerbation, Cell growth and Death and Transport and Catabolism decreased in abundance [1.6 (0.2-2.3) vs 3.6 (3.3-6.9), p = 0.012; and 1.8 (0-3.3) vs 3.6 (1.8-5.1), p = 0.025 respectively], while Cancer and Carbohydrate Metabolism increased [0.8 (0-1.5) vs 0 (0-0.5), p = 0.043; and 7 (6.4-9) vs 5.9 (6.3-6.1), p = 0.012 respectively]. In conclusion, the bronchial microbiome as a whole is not significantly modified when exacerbation symptoms appear in severe COPD patients, but its functional metabolic capabilities show significant changes in several pathways.

    Bronchial thermoplasty (BT) involves the application of radiofrequency energy to visible proximal airways to selectively ablate airway smooth muscle. BT is the first nonpharmacologic interventional therapy approved by the US Food and Drug Administration (FDA) for severe asthma. This approval was based on the results of the pivotal Asthma Intervention Research (AIR)-2 trial, which is the only randomized, double-blind, sham-controlled trial of BT. The primary end point of the AIR-2 trial was improvement in the Asthma Quality of Life Questionnaire (AQLQ). The results of the AIR-2 trial have generated enormous interest, controversy, and confusion regarding the true efficacy of BT for severe asthma. Current marketing of BT highlights its use for patients with "severe" asthma, which is interpreted by most practicing clinicians as meaning oral corticosteroid dependence, frequent exacerbations, or a significantly reduced FEV1 with a poor quality of life. Did the AIR-2 trial include patients with a low FEV1, oral steroid dependence, or frequent exacerbations? Did the trial show efficacy for any of the primary or secondary end points? The FDA approved the device based on the reduction in severe asthma exacerbations. However, were the rates of asthma exacerbations, ED visits, or hospitalizations truly different between the two groups, and was this type of analysis even justified given the original study design? This commentary is designed to specifically answer these questions and help the practicing clinician navigate the thermoplasty literature with confidence and clarity. We carefully dissect the design, conduct, and results of the AIR-2 trial and raise serious questions about the efficacy of bronchial thermoplasty.

    Aim: In this study, it was aimed to determine the problems of the neonates who were diagnosed with congenital heart disease requiring early intervention in our hospital. Material and Methods: The files of the newborn babies with congenital heart disease requiring early intervention who were admitted to the neonatal intensive care unit of our hospital between January 2011 and January 2013 were evaluated retrospectively. In all cases, echocardiography and ‘’Score for Neonatal Acute Physiology-II” (SNAP-II) scoring were performed within the first day of admission. The data were interpreted using Number Cruncher Statistical System 2007 software. The statistical significance was set at p<0.05. Results: A total of 83 babies were included in the study. Forty six of the patients were male (55%), and 37 (45%) were female. Sixty eight percent of the patients were referred from the neighboring provinces and 32% were transferred from the centers within the city. The age range was between 0 and 28 (5.6±6.4 day) days. The SNAP-II scores upon admission ranged between 0 and 90 (mean: 20±20.3). None of the patients was diagnosed prenatally. The most common diagnoses included transposition of the great arteries (33.7%) and pulmonary atresia (19.3%). Nineteen (22%) patients were lost in the neonatal intensive care unit. There was a significant relationship between the mortality and the SNAP-II scores (p=0.0001) and use of vasopressors (p=0.004). The diagnosis, gender, use of alprostadil and age were not related to mortality. Three patients were discharged following planning of elective surgery and 60 patients were referred to a tertiary center by air ambulance. Conclusions: The results of our study indicated that prenatal diagnosis could not be made in neonates with congenital heart disease requiring intervention in our region. The mortality rates of these patients were related to the severity of the clinical status at presentation rather than to the age, gender and type of

    PURPOSE: This paper describes the surgical rehabilitation of a child with craniofacial anomalies, unilateral syndactyly, and partial unilateral cryptophthalmos associated with inferior colobomata of the iris and optic nerve and agenesis of the inferior rectus and inferior oblique muscles. The clinical presentation of cryptophthalmos is described. METHODS: The medical literature since the original description of cryptophthalmos in 1872 was reviewed to define patterns of inheritance and the incidence of associated anomalies. RESULTS: Including this patient, 149 case reports of cryptophthalmos were identified. In two families transmission from parent to child suggests dominant inheritance. None of the five dominant cases had any other anomalies, and all had bilateral complete cryptophthalmos. The incidence of cryptophthalmos in the remaining families is consistent with autosomal recessive inheritance. This group includes patients with bilateral, unilateral, and partial cryptophthalmos. Other anomalies are common, including those of the ear and nose, limbs, genitourinary system, and mouth and palate. Mortality in the perinatal period is associated with renal agenesis, laryngeal atresia, and pulmonary hypoplasia. CONCLUSIONS: Cryptophthalmos is a rare congenital anomaly with two patterns of inheritance.

    The aim of the study was to evaluate, in a sample of young asthmatics in Italy, the current practice in assessment and treatment of asthma after the publication of guidelines. Young soldiers who declared bronchial asthma at the beginning of the compulsory military service were evaluated. One-hundred and thirty-eight subjects with confirmed asthma were selected. Sixty-seven subjects (48.5%) had had at last one spirometry, and only one subject had underwent peak flow monitoring at home; most of the subjects (96.8%) had had prick tests. More of the 50% of the subjects with bronchial obstruction or with severe bronchial hyperresponsiveness, with clinical moderate or severe asthma, had used only bronchodilators or no therapy at all in the preceding year. In this sample of young asthmatics, the lung function tests were still underutilized for the diagnosis and follow-up of bronchial asthma; moreover, the inhaled anti-inflammatory drugs were still underutilized.

    Congenital heart disease is associated with abnormal ventricular shape that can affect wall mechanics and may be predictive of long-term adverse outcomes. Atlas-based parametric shape analysis was used to analyze ventricular geometries of eight adolescent or adult single-ventricle CHD patients with tricuspid atresia and Fontans. These patients were compared with an "atlas" of non-congenital asymptomatic volunteers, resulting in a set of z-scores which quantify deviations from the control population distribution on a patient-by-patient basis. We examined the potential of these scores to: (1) quantify abnormalities of ventricular geometry in single ventricle physiologies relative to the normal population; (2) comprehensively quantify wall motion in CHD patients; and (3) identify possible relationships between ventricular shape and wall motion that may reflect underlying functional defects or remodeling in CHD patients. CHD ventricular geometries at end-diastole and end-systole were individually compared with statistical shape properties of an asymptomatic population from the Cardiac Atlas Project. Shape analysis-derived model properties, and myocardial wall motions between end-diastole and end-systole, were compared with physician observations of clinical functional parameters. Relationships between altered shape and altered function were evaluated via correlations between atlas-based shape and wall motion scores. Atlas-based shape analysis identified a diverse set of specific quantifiable abnormalities in ventricular geometry or myocardial wall motion in all subjects. Moreover, this initial cohort displayed significant relationships between specific shape abnormalities such as increased ventricular sphericity and functional defects in myocardial deformation, such as decreased long-axis wall motion. These findings suggest that atlas-based ventricular shape analysis may be a useful new tool in the management of patients with CHD who are at risk of impaired ventricular

    Most patients with single ventricle (SV) congenital heart disease are expected to survive to adulthood. Women with SV are often counseled against pregnancy; however, data on pregnancies in these women are lacking. We sought to evaluate in-hospital outcomes of pregnancy in women with SV. We used nationally representative data from the 1998 to 2012 National Inpatient Sample to identify women ≥18 years of age admitted to the hospital with International Classification of Diseases-9th Revision codes for an intrauterine pregnancy and a diagnosis of hypoplastic left heart syndrome, tricuspid atresia, or common ventricle. A matched comparison group without a diagnosis of congenital heart disease or pulmonary hypertension was identified from the database. National estimates of hospitalizations were calculated. Length of stay, hospital charges, and complications were analyzed and compared between groups. Charge data were adjusted to 2012 dollars. There were 282 admissions of pregnant women with SV (69% with deliveries) and 1,405 admissions in the control group (88% with deliveries). Vaginal delivery was more common in SV (74% vs 71%, p <0.001). Length of stay (4.1 ± 0.91 vs 2.8 ± 0.18 days, p <0.001) and charges ($30,787 ± 8,109 vs $15,536 ± 1,006, p <0.0001) were higher in the SV group. Complications occurred in most SV admissions and were more common in the SV group than in the control group. No deaths occurred. Cardiovascular complications occurred in 25% of pregnancy-related hospitalizations, although in-hospital pregnancy-related death is rare. Vaginal delivery is common in these patients. These data suggest that pregnancy and vaginal delivery can be tolerated in women with SV, although the risk for a cardiovascular event is significantly higher than in the general population.

    An indexed offset distance of the tricuspid septal leaflet ⩾8 mm/m2 is a quantitative criterion for the diagnosis of Ebstein's anomaly. The purpose of this study was to investigate the validity of this criterion for the discrimination of Ebstein's anomaly from pulmonary atresia with intact ventricular septum in neonatal patients. A total of 122 neonatal patients, 56 with Ebstein's anomaly and 66 with pulmonary atresia with intact ventricular septum, were enrolled. Diagnosis of each anomaly was based on typical morphologic features. Echocardiographic variables, including the offset distance of the tricuspid septal leaflet, were measured via an offline analysis of images recorded before 1 month of age. The offset distance of the tricuspid septal leaflet was indexed by the body surface area, and the indexed offset distances in the Ebstein's anomaly and pulmonary atresia with intact ventricular septum groups were 34.2 mm/m2 (7.1-119.1 mm/m2) and 7.2 mm/m2 (0.0-25.6 mm/m2), respectively. The indexed offset distance was ⩾8 mm/m2 in 29 (43.9%) of the patients with pulmonary atresia with intact ventricular septum; clinical and echocardiographic characteristics were comparable between these 29 patients and the remaining 37 patients with pulmonary atresia with intact ventricular septum. When an indexed offset distance ⩾8 mm/m2 was applied as a cut-off for the diagnosis of Ebstein's anomaly, the sensitivity was 0.963 and the specificity was 0.561. In conclusion, indexed offset distance ⩾8 mm/m2 cannot be used as a cut-off for the diagnosis of complicated Ebstein's anomaly in neonatal patients with pulmonary atresia with intact ventricular septum.

    Ranulas are cystic lesions in the floor of the mouth. They are either retention cysts of the excretory duct of the sublingual gland or pseudocysts formed by excretory duct rupture followed by extravasation and accumulation of mucus in the surrounding tissue. We report the case of a premature newborn with a congenital ranula in the floor of mouth. The ranula caused no discomfort or complications, so that immediate intervention was not necessary. The cyst resolved completely by the age of 4 months. Complications in newborns especially include airway obstruction and feeding difficulties. Surgical treatment options are needle aspiration, excision of the ranula, marsupialization, cryosurgery, and--in addition to excision of the cyst--removal of the ipsilateral sublingual gland. Sclerotherapy has shown good results as well. As many congenital cysts resolve or rupture spontaneously, they should be observed for potential resolution for several months in uncomplicated cases.

    Congenital syphilis is a severe, disabling infection that occurs due to the transmission of Treponema pallidum across the placenta during pregnancy or from contact with an infectious genital lesion during delivery. However, its early diagnosis is often difficult because more than half of the affected infants are asymptomatic, and the signs in symptomatic infants may be subtle and nonspecific. Although its incidence is declining, this long-forgotten disease continues to affect pregnant women, resulting in considerable perinatal morbidity and mortality. We hereby report a case of a 2-month-old infant with early congenital syphilis presenting with joint swellings and Parrot's pseudoparalysis, a comparative rarity in the present scenario. The report also stresses upon the importance of implementing the Centres for Disease Control and Prevention recommendation that all the pregnant women should be screened for syphilis in the first antenatal visit in the first trimester and again in late pregnancy.

    There were 47 patients with congenital muscular torticollis who underwent operative release. After a mean follow-up of 74 months (60 to 90), they were divided into two groups, one aged one to four years (group 1) and the other aged five to 16 years (group 2). The outcomes were assessed by evaluating the following parameters: deficits of lateral flexion and rotation, craniofacial asymmetry, surgical scarring, residual contracture, subjective evaluation and degree of head tilt. The craniofacial asymmetry, residual contracture, subjective evaluation and overall scores were similar in both groups. However, group 2 showed superior results to group 1 in terms of the deficits of movement, surgical scarring and degree of head tilt. It is recommended that operative treatment for congenital muscular torticollis is postponed until the patient can comply successfully with post-operative bracing and an exercise programme.

    Cardiovascular malformations are the most common type of birth defect and result in significant mortality worldwide. The etiology for the majority of these anomalies remains unknown but genetic factors are being recognized as playing an increasingly important role. Advances in our molecular understanding of normal heart development have led to the identification of numerous genes necessary for cardiac morphogenesis. This work has aided the discovery of an increasing number of monogenic causes of human cardiovascular malformations. More recently, studies have identified single nucleotide polymorphisms and submicroscopic copy number abnormalities as having a role in the pathogenesis of congenital heart disease. This review discusses these discoveries and summarizes our increasing understanding of the genetic basis of congenital heart disease. PMID:21532774

    The story of congenital heart disease is one of the major successes of medicine in the last 50 years. Heart conditions previously associated with early death are now successfully treated. Many of these women are now in their child-bearing years wishing to have children of their own. All of these women should be offered comprehensive pre-conception counselling by a dedicated multi-disciplinary team. Each woman will present a unique set of cardiac and obstetric challenges that require an individualised assessment of risk and a carefully documented care plan. In this chapter, I describe the most common forms of congenital heart disease and the specific issues that should be assessed before conception. I present a systematic approach to risk stratification and care planning. These lesions range from mild disease with little implications for pregnancy to those with a sizable risk of maternal mortality or complications. I will also discuss fetal risk factors.

    Four closely related domestic shorthair kittens were investigated following the detection of abnormalities in their gait, difficulty opening their mouths and muscle hypertrophy. They walked with a stiff, stilted gait, with the stiffness reducing during exercise. Startling of the kittens resulted in hyperextension of the limbs and falling to lateral recumbency, or spasm of the orbicularis oculi muscle, prolonged prolapse of the nictitating membranes and flattening of the ears. One kitten was intermittently dysphonic. Endotracheal intubation of the anaesthetised kittens was difficult due to an inability to open the mouth to a wide angle, and narrowing of the glottis due to muscle spasm. A diagnosis of congenital myotonia was made based on the clinical signs, the kittens' ages, typical myotonic discharges on electromyography, and the histopathological and histochemical findings in muscle. This is the first report of congenital myotonia in this species.

  12. Classifying sex biased congenital anomalies

    The reasons for sex biases in congenital anomalies that arise before structural or hormonal dimorphisms are established has long been unclear. A review of such disorders shows that patterning and tissue anomalies are female biased, and structural findings are more common in males. This suggests different gender dependent susceptibilities to developmental disturbances, with female vulnerabilities focused on early blastogenesis/determination, while males are more likely to involve later organogenesis/morphogenesis. A dual origin for some anomalies explains paradoxical reductions of sex biases with greater severity (i.e., multiple rather than single malformations), presumably as more severe events increase the involvement of an otherwise minor process with opposite biases to those of the primary mechanism. The cause for these sex differences is unknown, but early dimorphisms, such as differences in growth or presence of H-Y antigen, may be responsible. This model provides a useful rationale for understanding and classifying sex-biased congenital anomalies. 42 refs., 7 tabs.

    In this article, we consider tumors that are diagnosed during pregnancy or in the first three months of life. This is a heterogeneous group of neoplasms with special biological and epidemiological characteristics that differentiate them from tumors arising in children or adults. In the last two decades, the prenatal detection of congenital tumors has increased due to the generalized use of prenatal sonographic screening. Advances in imaging techniques, especially in fetal magnetic resonance imaging, have enabled improvements in the diagnosis, follow-up, clinical management, and perinatal treatment of these tumors. This image-based review of the most common congenital tumors describes their histologic types, locations, and characteristics on the different imaging techniques used.

    Biliary atresia is an inflammatory cholangiopathy of still undetermined etiology. Correlations between histologic findings and clinical outcome in this disease have largely been based on evaluation of liver parenchyma. This study aimed to characterize the pattern of inflammation within the biliary remnant and identify associations between the type and degree of inflammation and clinical outcome as reflected by the transplant-free interval. The inflammation within the fibrous plates and livers of 41 patients with biliary atresia was characterized using immunohistochemical markers and the cell populations were digitally quantified. The type and quantity of cells within the infiltrate were then correlated with length of time from Kasai portoenterostomy until transplant. Histologic and immunohistochemical features of the biliary remnant allowed stratification of patients into "inflammatory plate" and "fibrotic plate" groups. Overall there was no significant difference in transplant-free interval between the two cohorts; however, there was a trend towards a longer time to transplant among patients in the "fibrotic plate" group. In addition, the composition of the inflammatory infiltrate in the fibrous plate was distinctly different from that present in the liver and only the characteristics of the inflammation in the fibrous plate, in particular the number of Foxp3+ T regulatory lymphocytes correlated with clinical outcome. The results of this study support the view of the extra-hepatic biliary tree as the primary site of injury in BA with the changes seen in the liver as secondary manifestations of outflow obstruction. The association between specific inflammatory cell subtypes within the fibrous plate and the length of transplant-free interval also supports the role of the immune system in the initial process of bile duct damage in biliary atresia.

    Tracheal and bronchial injury, including iatrogenic injury and traumatic injury, the former usually occurred in the operation, intubation or bronchoscopy. The latter was occurred in a variety of blunt trauma, often combined with a variety of complex injuries. The therapeutic approach can be differentiated, surgical or conservative, no criteria has been universally accepted. Successful treatment of tracheobronchial injuries requires early diagnostic evaluation. This article aims to review the indications and therapeutic options for tracheal and bronchial injuries.

    Fifteen patients with bronchial carcinoma were treated with infusions of 10 mg Mitomycin C (MMC) in the bronchial artery feeding the tumor. The treatment was repeated three times with 2-3 weeks interval between treatments. Half of the patients then received radiation to the tumor area and mediastinum. All tumors decreased in size, complete remission occurred in two and partial remission in five patients. Survival time, however, was not prolonged and esophageal complications occurred in several patients.

    Left bronchial obstruction is a rare complication after neonatal aortic arch reconstruction. This article describes the surgical management of a neonate with hypoplastic left heart syndrome who underwent a stage 1 Norwood reconstruction. A mediastinal infection developed with an abscess that caused left bronchial obstruction and disruption. The left bronchus was repaired successfully by using a pedicle intercostal muscle flap that was used to cover the defect.

    Congenital heart diseases are a frequent cause of cardiology consultation. New diagnostic and therapeutic techniques have allowed greater survival and quality of life of patients who wish to participate in sports. What they can do is not always easy to determine. Guidelines are helpful at the time of deciding, although finally is the doctor the one that must determine in each case the situation of the patient and the type of exercise they can do depending on the severity and type of cardiopathy.
