    2009-01-01

    A 43-year-old man presented with dizziness, head instability, and facial reddening, always in relation to body posture and without fever or systemic manifestations. Chest radiography revealed a large cavity with an air-fluid level in the right upper hemithorax. A right upper lobectomy was performed to remove a large bronchogenic cyst. The presentation with cardiac but no respiratory symptoms is uncommon but should be considered in the differential diagnosis of patients with intrathoracic cysts. PMID:19515886

    Bronchogenic cyst (BC) is a rare congenital malformation of the lung. Most patients remain asymptomatic until adulthood while some are symptomatic in the first few years of life. However, symptoms in newborn period are rare. We report a case of a 3-day-old preterm baby with respiratory distress diagnosed as congenital lobar emphysema on chest X-ray. A CT scan revealed a mediastinal cyst causing obstructive lobar emphysema. The cyst was excised and pathological examination was suggestive of BC. PMID:27609589

    Although it is estimated that > 1 billion passengers travel by air worldwide each year, the incidence of in-flight emergencies is low. However, due to nonstandardized reporting requirements for in-flight medical emergencies, the true incidence of pulmonary barotrauma in airplane passengers is unknown. We describe the case of a passenger with an asymptomatic intrapulmonary cyst in whom a severe case of cerebral gas embolism developed during an aircraft flight. The decrease in ambient pressure during the aircraft climb resulted in expansion of the cyst volume based on Boyle's law (pressure x volume = constant). Due to the cyst expansion, we believe tears in the wall led to the leakage of air into the surrounding vessels followed by brain gas emboli. Adult patients with intrapulmonary cysts should be strongly considered for cyst resection or should at least be advised to abstain from activities leading to considerable changes in ambient pressure.

    Bronchogenic cyst is a rare congenital (developmental) anomaly. It is usually asymptomatic but its enlargement and localization may cause serious symptoms. Exact preoperative diagnosis is rarely established. As a rule, it is established during histological examination of the resected specimen. We present a patient with a subdiaphragmatic retroperitoneal bronchogenic cyst in whom exact diagnosis was documented by histological examination of excised cyst. To our knowledge this is the third such case ever reported.

    Bronchogenic cyst is a relatively rare abnormality that develop from the accessory lung buds of the foregut. The cyst is regarded as a congenital developmental abnormality. Occurence in the retroperitoneal presentation is rare. Here, we present two patients who had an incidentally discovered retroperitoneal mass which were revealed to be bronchogenic cysts after surgical extirpation.

    Bronchogenic cysts are benign congenital malformations usually. A retroperitoneal location is extremely uncommon. We reported a case of bronchogenic cyst occurred in the retroperitoneum in a 60-year-old patient. An abdominal CT for a prostatic adenocarcinoma staging has reported this incidental lesion. Biological, radiological and histological assessment confirmed the bronchogenic cyst diagnosis. The treatment of choice for most authors is surgical excision. However, because of a low malignant transformation risk, we have chosen a follow-up with abdominal computerized tomography every 6 months. During 3 years, biological and radiological assessments have shown a stable lesion. Therefore, it seems reasonable to propose a simple radiological monitoring for bronchogenic cysts in selected patients.

    Bronchogenic cysts are relatively rare congenital anomalies that represent malformations of the embryonic foregut and are morphologically expressed as maldevelopments of the respiratory system. Anatomically, they can be positioned at any location along the central axis of the respiratory system, but are more commonly discovered in the thorax. Infradiaphragmatic bronchogenic cysts are rare and retroperitoneal ones distinctly unusual. We report a retroperitoneal bronchogenic cyst clinically masquerading as a phaeochromocytoma.

    Bronchogenic cysts are rare congenital malformation that need surgical removal. To date, bronchogenic cysts located in highest upper mediastinum excised by thoracoscopy have not been reported, though complete thoracoscopic extirpation of a bronchogenic cyst has been reported before. We excised two highest upper bronchogenic cysts by thoracoscopy successfully without any postoperative complication, demonstrating thoracoscopy could be a first-line therapeutic option even for highest upper mediastinum brochogenic cysts.

    We report a case of intrapulmonary solitary fibrous tumor( SFT). A 34-year-old woman was referred to our hospital due to an abnormal shadow on a chest roentgenogram without symptom. Computed tomography showed a circumscribed intrapulmonary tumor with mild uptake on fluorodeoxyglucose (FDG)-positron emission tomography( PET) in the left lower lobe( S6). Frozen examination revealed a mesenchymal tumor. Based on the pathological and immunohistochemical findings, the tumor was diagnosed as intrapulmonary SFT.

    A rare case of retroperitoneal bronchogenic cyst is presented. A 50-year-old man was referred to our hospital for an investigation of a retroperitoneal mass. Computed tomography and magnetic resonance imaging confirmed a retroperitoneal mass, about 4 cm in diameter, adjacent to the left kidney and spleen. On the basis of these imaging modalities, a definitive diagnosis of this mass could not be made. So, resection of the mass was performed. The removed mass was an unilocular cyst and filled with mucinous fluid. Histopathologically, the cyst wall was composed of a fibrovascular connective tissue containing mucus-secreting glands and cartilages and was lined by ciliated pseudostratified columnar epitherium. Thus, a diagnosis of bronchogenic cyst was made. Bronchogenic cysts are rare congenital anomalies of the primitive foregut and usually develop in the mediastinum and lung.

    Only a few subdiaphragmatic bronchogenic cysts are described, and their occurrence in the retroperitoneum is extremely rare. So far, only a few cases have been reported in the English-language literature. The pathogenesis is caused by the pinching off of irregular lung budding of the primitive ventral foregut, with aberrant migration into the abdomen before fusion of the diaphragm during embryonal development. A unique case with clinical, radiographic, surgical finding is presented. Final pathological findings confirmed the diagnosis of retroperitoneal bronchogenic cyst without other associated congenital anomalies. Retroperitoneal bronchogenic cyst, although rare, should be considered in the differential diagnosis in the retroperitoneal mass. This rare case is described and the relevant literature, reviewed.

    Bronchogenic cysts are mostly benign, congenital abnormalities originating from the remnants of the primitive foregut. A retroperitoneal location is rare. Due to the mostly asymptomatic behavior and the historical confusion regarding histology, an exact prevalence is not known. We present here a case report of a retroperitoneal bronchogenic cyst. A literature review was performed for cases of retroperitoneal bronchogenic cysts written in English. Anatomopathological criteria for inclusion were pseudo stratified, ciliated, columnar epithelium together with the presence of at least one of the following: cartilage, smooth muscle or seromucous glands. In addition, the embryology, pathogenesis, radiological, clinical and suggested treatment modalities are reviewed. We report the surgical excision of a retroperitoneal bronchogenic cyst that presented as a non-functioning left adrenal mass. Our review of literature revealed only 62 potential cases of retroperitoneal bronchogenic cysts. After applying the strict anatomopathological criteria, only 30 cases of true retroperitoneal bronchogenic cysts could be identified. Retroperitoneal location of a bronchogenic cyst is rare. Despite the rarity of this pathologic entity, bronchogenic cysts should be considered in the differential diagnosis of retroperitoneal cystic lesions. Only histology can confirm definitive diagnosis. Surgery remains the recommended treatment of choice.

    Bronchogenic cysts are generally found in the mediastinum, particularly posterior to the carina, but they rarely occur in such unusual sites as the skin, subcutaneous tissue, pericardium, and even the retroperitoneum. A 30-year-old Korean man underwent surgery to remove a cystic adrenal mass incidentally discovered during routine physical checkup. At surgery, it proved to be a multilocular cyst located in the retroperitoneum adjacent to the left adrenal gland. Microscopically, the cyst was lined by respiratory epithelium over connective tissue with submucous glands, cartilage and smooth muscle, thereby histologically confirming bronchogenic cyst. This is the first reported case of retroperitoneal bronchogenic cyst in an adult without other congenital anomalies in Korea.

    Bronchogenic cysts are uncommon, predominantly benign, congenital malformations arising from the primitive foregut. The occurrence of such cysts in the retroperitoneum is extremely rare. The present study presents the case of a 30-year-old female who presented with a left adrenal mass. Imaging investigations revealed a cystic mass located medially to the left adrenal gland. Retroperitoneal laparoscopic excision and complete resection were performed, and the subsequent pathological examination confirmed the diagnosis of a bronchogenic cyst in the retroperitoneum. The patient was discharged on the fourth post-operative day and received no further treatment, however, regular follow-up was performed due to the lesion being benign. A rare case of bronchogenic cyst and literature review is presented, which may aid in improving the understanding of the etiology and pathogenesis of retroperitoneum bronchogenic cysts.

    Bronchogenic cysts are benign lesions, which are usually described at the chest level. We present here a case report of a retroperitoneal bronchogenic cyst. A 77-year-old man presented with a left retroperitoneal tumor discovered by scanner. There was no endocrine disruption. Excision of the lesion was performed and final diagnosis was a bronchogenic cyst. Current widespread use of modern radiology enables increased discovery of such "incidentalomes". In the future, pathologists will be routinely faced with this type of diagnosis, which up to now has been described as exceptional.

    Retroperitoneal cystic tumors are uncommon. More than two thirds are malignant. Benign lesions include lipomas and leiomyomas, among others. Bronchogenic cysts are congenital anomalies that result from an abnormal budding of the primitive foregut, and are most commonly found in the mediastinum. Occasionally they can be seen in the skin, subcutaneous tissue, in the pre-sternal and pericardial areas, but those located under the diaphragm are extremely rare. We report a 24 year-old female who consulted for abdominal pain. An abdominal ultrasound disclosed a retroperitoneal cystic lesion, that was confirmed with a CAT scan. The patient was operated, finding a cyst that was adhered to the pancreas. A distal pancreatectomy and cyst excision were done. The pathological examination of the lesion showed a bronchogenic cyst. The patient was discharged ten days after surgery.

    Purpose: Bronchogenic cysts are rare benign congenital anomalies, originating from the embryonic foregut ventral segment. Adrenal bronchogenic cyst is a rare form of this anomaly. One extremely rare case of bilateral adrenal multilocular bronchogenic cyst in our hospital was reported and the relevant literatures were reviewed. Significant findings: A 51-year-old man suffered from an intermittent vague headache, fatigue and hypertension history for 2 years, which were gradually worsened in a week. Imaging tests showed bilateral suprarenal mass and left renal cysts. After underwent two retroperitoneal laparoscopic adrenal gland tumor separately, they were all proved to be both the multilocular bronchogenic cyst located in bilateral adrenal gland by histopathological examination. Conclusions: This report confirms the bronchogenic cyst that can be involved bilateral joint in the adrenal gland. And we demonstrated retroperitoneoscopic surgical management is effective in the treatment of the disease. PMID:25031770

    The diagnosis of primary retroperitoneal cystic tumors is very infrequent in surgical pathology. We report the case of a 51-year-old woman presenting with an incidental left-sided retroperitoneal mass (32 x 24 mm in diameter) suspected of being an adrenal tumor. Intraoperatively the tumor was identified as a cystic lesion filled with mucous secretion and laparoscopically completely resected. The diagnosis was histopathologically confirmed as a bronchogenic cyst. In this article the laparoscopic removal of such a rare benign congenital aberration resulting from an abnormal budding of the tracheobronchial tree is presented.

    We report the surgical excision of a retroperitoneal bronchogenic cyst that presented as a nonfunctioning left adrenal mass in a 25-year-old woman with continuous pain in the left flank. Preoperative biochemical testing confirmed that the mass was nonfunctional. Bronchogenic cysts are mostly benign congenital abnormalities that originate from the remnants of the primitive foregut and typically occur in the lung. Subdiaphragmatic and especially, retroperitoneal locations are rare. Despite the rarity of this pathologic entity, bronchogenic cysts should be considered in the differential diagnosis of retroperitoneal cystic lesions. Diagnosis must be definitively confirmed by histology.

    Bronchogenic cysts are among developmental disorders of the primitive foregut which are typically found above the diaphragm. Bronchial cysts discovered in the abdominal cavity or retroperitoneum are extremely rare. We present a rare case of a retroperitoneal bronchogenic cyst which was incidentally detected after a wrestling injury in a 23-year-old man who had a negative medical history. Although initial imaging studies suggested an adrenal tumor, histopathological analysis provided a definite diagnosis of bronchogenic cyst. Though rare, bronchogenic cysts must be considered in the differential diagnosis of retroperitoneal cystic lesions. This is the first case of a retroperitoneal bronchogenic cyst reported in Iran.

    An intra-abdominal bronchogenic cyst (BC) is a very rare congenital anomaly caused by abnormal budding of the developing tracheobronchial tree. Intra-abdominal BCs are reported as retroperitoneal masses in most cases, many of which are located on the left side of the midline, the perigastric area, the left adrenal gland, or the superior body of the pancreas. Intra-abdominal BCs are frequently misdiagnosed due to the rarity, location, and variable cystic content. We report five patients with intra-abdominal BCs who underwent surgery in a single institution.

    Retroperitoneal bronchogenic cyst is detected extremely rarely and often masquerades as other diseases. Here, we report 2 cases of retroperitoneal bronchogenic cyst mimicking pancreatic mucinous tumor. Histologically, both cysts were composed of ciliated respiratory-like epithelium with abundant mucin content, smooth muscle bundles and mature cartilage, compatible with the diagnosis of retroperitoneal bronchogenic cyst. In addition to these 2 cases, another 42 retroperitoneal bronchogenic cysts reported in the English literature were collected for review and analysis. Twelve (28%) were located over the peripancreatic area. Just over half (51%) of them were asymptomatic. No accurate preoperative diagnosis could be made for any of the lesions. About a third (33.3%) of the peripancreatic retroperitoneal bronchogenic cysts masqueraded as pancreatic cystic lesions.

    Congenital pulmonary malformations represent a broad spectrum of anomalies that may result in varied clinical and pathologic pictures, ranging from recurrent pulmonary infections and acute respiratory distress syndrome, which require timely drug therapy, up to large space-occupying lesions needing surgical treatment. This classification includes three distinct anatomical and pathological entities, represented by Congenital Cystic Adenomatoid Malformation, Bronchopulmonary Sequestration and Congenital Lobar Emphysema. The final result in terms of embryological and fetal development of these alterations is a Congenital Lung Hypoplasia. Since even Bronchial Atresia, Pulmonary Bronchogenic Cysts and Congenital Diaphragmatic Hernias are due to Pulmonary Hypoplasia, these diseases will be discussed in this review (1, 2). PMID:27467867

    Isolated abdominal bronchogenic cysts are extremely rare. We report the fourth such case in an asymptomatic 4-year-old girl who initially presented for evaluation of urinary tract infection and new-onset urinary incontinence. Ultrasound, computed tomography, and magnetic resonance imaging findings were consistent with an adrenal mass. At exploration, the patient was found to have a mass in the area of the gastroesophageal junction and a normal left adrenal gland. The final pathology confirmed the diagnosis of a bronchogenic cyst. Abdominal bronchogenic cysts, although rare, should be considered in the diagnosis of a retroperitoneal mass.

    Isolated abdominal bronchogenic cysts are rare abnormalities. They are usually asymptomatic unless secondarily infected or large enough to cause compression of other vital structures. The authors report on a 20-month-old girl who had an abdominal bronchogenic cyst and presented with a history of recurrent urinary tract infections. The evaluation and treatment of this patient is presented as well as a review of the ten previously reported cases. A literature review showed only four cases in the pediatric age group. Excision is recommended to establish diagnosis and alleviate any symptoms. Abdominal bronchogenic cysts should be considered in the differential diagnosis of retroperitoneal masses.

    Bronchogenic cyst is a benign lesion which is commonly seen in the posterior mediastinum. Diaphragmatic origin in retroperitoneum is an unusual location for a bronchogenic cyst. Cross-sectional imaging modalities describe the origin and content of the cyst evidently. Magnetic resonance (MR) images of a 42-year-old male patient who attended ER with back pain revealed a huge retroperitoneal complicated bronchogenic cyst arising from the diaphragm and surrounding the abdominal aorta anteriorly. Bronchogenic cysts in the retroperitoneum rarely originate from the diaphragm and should be kept in mind in the differential diagnoses of abdominal cystic lesions. MR imaging (MRI) is superior to other imaging techniques such as computerized tomography (CT) in detecting the origin and content of these cystic lesions.

Preoperative imaging studies and operative findings showed a broad-based cystic mass on the left lower posterior pleura and diaphragmatic pleura extending into the retroperitoneal region across the diaphragm. Histologic studies proved this mass to be a bronchogenic cyst.

    Bronchogenic cysts frequently occur in the mediastinum. They may be rarely encountered in the abdomen and retroperitoneum. Bronchogenic cysts can in fact mimic hydatid cysts. We report a case of retroperitoneal bronchogenic cyst below the right hemidiaphragm mimicking a hydatid cyst of the liver in a 30-year-old female.

    Fibrosing mediastinitis is a rare but benign disorder characterized by an excessive fibrotic reaction in the mediastinum which can result in compromise of airways, great vessels, and other mediastinal structures. In this paper we presented a patient with fibrosing mediastinitis mimicking bronchogenic carcinoma. The patient was a 32-year-old diabetic male admitting with cough and hemoptysis. There was a right hilar mass and multiple mediastinal conglomerated lymph nodes on chest computed tomography. Positron emission tomography with computed tomography (PET/CT) scan demonstrated increased fluorodeoxyglucose (FDG) uptake at the right hilar mass lesion and mediastinal lymph nodes. Fiberoptic bronchoscopy showed mucosal distortion of right upper lobe. Pathologic examination of the mucosal biopsy revealed inflammation. Endobronchial ultrasound guided transbronchial needle and cervical mediastinoscopic lymph node biopsies were undiagnostic. Diagnostic thoracotomy confirmed the diagnosis fibrosing mediastinitis. Administration of six months of systemic corticosteroid and antituberculous therapy was not beneficial. In conclusion, despite being a rare clinical entity, fibrosing mediastinitis should be kept in mind in the differential diagnosis of mediastinal mass lesions of unknown etiology. The diagnosis is exceptionally difficult in the presence of atypical radiological findings. The treatment is particularly challenging without any proven effective therapy. PMID:23372962

    Bronchogenic cysts (BCs) are congenital malformations that originate from remnants of the primitive foregut. Intraspinal BCs, especially those of the conus medullaris are rare with only one case reported until now. To date, a bronchogenic cyst with spinal cord tethering has not been previously reported. We reviewed the clinical course of a 44-year-old woman, who presented with low back pain and leg weakness as well as sphincter disturbance. Magnetic resonance imaging showed an intradural oval mass located at the conus medullaris. A tethered cord was also observed, as well as a dermal sinus tract. The mass was totally removed after an L3-L4 laminectomy without detethering during operation. Pathologic examination confirmed the diagnosis of bronchogenic cyst. By six months after treatment, the patient had experienced nearly complete recovery. The review of literature indicated that detethering was performed in most reported cases of neurenteric cysts with spinal cord tethering, and one of six patients was diagnosed with a postoperative recurrence. The co-existence of bronchogenic cyst and a tethered spinal cord would imply associated developmental errors in embryogenesis. It is worth noting that whether detethering is necessary after the cyst removal.

    A subdiaphragmatic, retroperitoneal bronchogenic cyst arising from the stomach is reported in a patient who was referred for evaluation of what was thought to be an adrenal tumor. To our knowledge, less than 20 cases of retroperitoneal bronchogenic cyst have been reported in the English literature. A bronchogenic cyst may be indistinguishable from an adrenal tumor and, although rare, should be considered in the differential diagnosis of a retroperitoneal mass.

We experienced a 66-year-old woman with an intrapulmonary SFT that recurred locally with malignant transformation 2 years after wedge resection of the left upper lobe for the primary tumor. Subsequently, she underwent a lobectomy of the residual left upper lobe. Six years after the second operation she was well, without rerecurrence. Complete excision and long-term follow-up of intrapulmonary SFTs of the pleura are important, even when the primary tumor displays benign histopathologic features.

    The association of hepatic cirrhosis and severe arterial hypoxemia has been well described. Although alterations in ventilatory function may partially account for the hypoxemia, the principal mechanism is thought to be a microangiopathic change in the pulmonary vasculature resulting in intrapulmonary arteriovenous shunting with resultant systemic desaturation. Whole-body radionuclide scans with technetium-99m macroaggregated albumin labeling have been diagnostic of right-to-left shunting by their demonstration of tracer accumulation within the extrapulmonary circulation. A case of severe pulmonary arteriovenous shunting in an alcoholic patient in whom hepatic disease had not been of apparent clinical significance before radionuclide scanning is reported. He did not have cuntaeous angiomata as have all other patients with alcoholic cirrhosis and hypoxemia.

A cyst below the left hemidiaphragm was discovered incidentally when a CT scan was performed to examine the thymus for a suspected tumor. A thymic mass was found. MRI indicated that the cyst contained proteinaceous fluid. The thymoma was approached through a median sternotomy and resected, but the cyst was found to be infradiaphragmatic. A separate, left paraspinal incision was made to access the retroperitoneum, and the cyst was resected. Histologic examination showed that the cyst was bronchogenic in origin. Retroperitoneal bronchogenic cysts are very rare, and only four cases have been reported in the English-language literature.

    The retroperitoneal bronchogenic cyst is an extremely rare anomaly. During the examination of an 18-year-old female patient due to her extreme thinness, the abdominal ultrasound and later the CT indicated as an accidental finding--a left side adrenal/suprarenal adenoma, which turned out to be hormonally inactive. But while we were doing a laparoscopic surgical intervention we found a 6-8-cm cyst in the retroperitoneum, between the greater curvature and the spleen. It contained light grey, mucinous liquid. The left suprarenal gland had normal size and appearance. During the microscopic examination the removed terime showed cystic structures, which were covered inside with multilayer ciliated columnar epithelium, mucous excretory glands, a whole layer of connective/interstitial and smooth muscle tissue. Neither cartilage, nor gastrointestinal epithelium was found. Only a few publications have reported about retroperitoneal bronchogenic cyst so far. These lesions occur very rarely at the greater curvature. Although this alteration is really unusual, bronchogenic cysts have to be expected in the differential diagnostics of the retroperitoneal tumors.

We report a 42-year-old female patient with a retroperitoneal bronchogenic cyst in the left adrenal region. She was admitted to our hospital with epigastric pain and subsequently underwent CT of the abdomen. The examination revealed a mass related to the left adrenal gland. Endocrine tests for adrenal hypersecretion were negative. Because of the uncertain entity, laparoscopic adrenalectomy was performed. Pathological examination revealed a bronchogenic cyst in proximity to an inconspicuous left adrenal gland. Although very rare, bronchogenic cysts should be considered in the differential diagnosis of retroperitoneal cystic lesions and surgical resection pursued for symptom resolution and to establish a definitive histology.

    The effect of flow of inspired gas on intrapulmonary gas distribution was examined by analysis of regional pulmonary /sup 133/Xe clearances and of total pulmonary /sup 133/Xe clearance measured at the mouth after equilibration of the lungs with /sup 133/Xe. Five awake healthy volunteers (24 to 40 yr of age) and another 5 healthy, anesthetized-paralyzed volunteers (26 to 28 yr of age) were studied while they were in the right lateral decubitus position. The awake subjects were studied at 3 inspiratory flows (0.4, 0.7, and 1.0 L/s) and the anesthetized-paralyzed subjects at 4 inspiratory flows (0.2, 0.5, 1.1, and 1.6 L/s). Interregional differences in /sup 133/Xe clearances along the vertical axis were significantly less during anesthesia-paralysis and mechanical ventilation than during spontaneous breathing in the awake state. No differences in the regional or total pulmonary /sup 133/Xe clearances were detected at these different flows in either of the two states, i.e., the difference between the awake and anesthetized-paralyzed states persisted.

    Development of intrapulmonary interstitial emphysema together with other forms of extraalveolar air collections following alveolar rupture was investigated retrospectively in 46 term and preterm newborn infants with respect to gestational age severity of pulmonary disease and mode of ventilatory assistance. Intrapulmonary interstitial emphysema was found in 31 of these 46 infants (67%). Development depended on the severity of pulmonary disease, mode of ventilatory assistance and level of inspiratory pressure. Intrapulmonary interstitial emphysema was found at an average age of 1 day (1-6 days) in 2 out of 23 infants (9%) during unassisted spontaneous breathing, in 8 out of 24 infants (33%) during CPAP and in 21 out of 26 infants (81%) during controlled ventilation. 18 out of these 31 infants (58%) additionally developed other forms of extraalveolar air collections but only in 9 from these interstitial emphysema has been found prior to other forms of extraalveolar air. Mortality rate of infants with intrapulmonary interstitial emphysema alone (10 out of 13; 77%) and infants who additionally developed other forms of extraalveolar air collections (16 out of 18; 89%) did not differ significantly. Development of intrapulmonary interstitial emphysema even in he absence of other forms of extraalveolar air collections has therefore to be judged as a severe complication in infants undergoing different forms of ventilatory assistance.

    This randomised, double-blind, placebo-controlled, cross-over study was designed to identify which pharmacodynamic parameters most accurately quantify the effects of delta-9-Tetrahydrocannabinol (THC), the predominantly psychoactive component of cannabis. In addition, we investigated the acceptability and usefulness of a novel mode of intrapulmonary THC administration using a Volcano vaporizer and pure THC instead of cannabis. Rising doses of THC (2, 4, 6 and 8 mg) or vehicle were administered with 90 minutes intervals to twelve healthy males using a Volcano vaporizer. Very low between-subject variability was observed in THC plasma concentrations, characterising the Volcano vaporizer as a suitable method for the administration of THC. Heart rate showed a sharp increase and rapid decline after each THC administration (8 mg: 19.4 bpm: 95% CI 13.2, 25.5). By contrast, dose dependent effects of body sway (8 mg: 108.5%: 95% CI 72.2%, 152.4%) and different subjective parameters did not return to baseline between doses (Visual Analogue Scales of 'alertness' (8 mg: -33.6 mm: 95% CI -41.6, -25.7), 'feeling high' (8 mg: 1.09 U: 95% CI 0.85, 1.33), 'external perception' (8 mg: 0.62 U: 95% CI 0.37, 0.86)). PK/PD-modeling of heart rate displayed a relatively short equilibration half-life of 7.68 min. CNS parameters showed equilibration half-lives ranging between 39.4 - 84.2 min. Some EEG-frequency bands, and pupil size showed small changes following the highest dose of THC. No changes were seen in saccadic eye movements, smooth pursuit and adaptive tracking performance. These results may be applicable in the development of novel cannabinoid agonists and antagonists, and in studies of the pharmacology and physiology of cannabinoid systems in humans. PMID:18515447

    Bronchogenic cysts arise from abnormal budding of the ventral diverticulum of the foregut or tracheobronchial tree during embryogenesis, are the most common cystic masses in the mediastinum, and are generally asymptomatic. A spontaneous regression in a mediastinal bronchogenic cyst (MBC) with pneumonia is rare. A 30-year-old male had a tumor shadow in the middle mediastinum. When he visited our hospital, he had a mild fever with coughing and sputum. A chest computed tomography (CT) scan showed a decrease in the tumor size and the existence of right pneumonia. MBC may be involved in the etiology of pneumonia; therefore, bronchogenic cysts need to be resected as soon as possible. PMID:26943430

    A 59-year-old hypertensive man was referred to our hospital with a retroperitoneal cystic tumor, measuring 6 cm in diameter that was detected by an ultrasound examination during routine check-up 2 years before coming to our department. During the 2-year follow-up, the cystic tumor gradually increased in size. The patient also became hypertensive with slightly elevated urine levels of noradrenaline and dopamine, while the plasma catecholamines and their metabolites in the urine were within the normal range. Computed tomographic scanning and magnetic resonance imaging revealed a dumbbell-shaped retroperitoneal cyst with dense fluid, measuring 7 x 3.5 x 3 cm in diameter, in the left supra-adrenal and sub-diaphragmatic regions. He underwent extirpation of the cystic tumor with suspicion of adrenal endocrine cystic tumor. The histopathological diagnosis was a bronchogenic cyst, which is an extremely rare developmental anomaly in the retroperitoneal space. We herein report this rare case of retroperitoneal bronchogenic cyst and present a brief review of the previously reported 30 Japanese cases.

    A unique case of adenocarcinoma arising in a retroperitoneal bronchogenic cyst is presented. A 55-year-old woman presented with lower abdominal discomfort. Computed tomography revealed a retroperitoneal cystic mass attached to the ascending colon. The resected cyst was unilocular and filled with milky white mucus and hemorrhagic debris. Histologically, most of the cyst wall was of well-differentiated papillary adenocarcinoma with no cyst wall invasion. Other small areas of the cyst were lined with variably atypical dysplastic/metaplastic cuboidal to pseudostratified columnar epithelium. The cyst wall was mostly hyalinized, but there was apparent thickened subepithelial basement membrane, elastosis, and a single layer of smooth muscle that suggested bronchial wall structures. A mucin staining study with O-acylated sialic acid, which is used for the demonstration of gastrointestinal, cholecystic and uterine cervical mucins, was negative for the mucin-producing epithelial cells of the cyst. Thus, to our knowledge, this is the first reported case of adenocarcinoma arising in a retroperitoneal bronchogenic cyst.

    Two children aged 8 and 15 years underwent excision of retroperitoneal bronchogenic cysts (RBC) via a posterior retroperitoneoscopic approach (RPA). The operative technique and efficacy of this approach are reviewed. One lesion was symptomatic, while the other was an incidental finding on abdominal ultrasound. Operating times were 45 and 55 min. One patient was discharged on the day of surgery, the other on the 1st postoperative day. Both returned to normal physical activities within 1 week of surgery. No complication occurred in either case. To our knowledge, this is the first description in the literature of excision of this rare lesion via a RPA. We conclude that this is a safe method for resection of RBCs that offers several potential advantages compared with the open technique.

    Bronchogenic cysts are foregut-derived developmental anomalies most commonly encountered in the mediastinum and rarely in the abdomen or retroperitoneally. A comprehensive review of the English-language literature of subdiaphragmatic bronchogenic cysts (sBCs) revealed only 48 reported cases of sBC. Although most cases are incidentally discovered, preoperative differential diagnosis often includes tumors with malignant potential and necessitates surgical resection to obtain a definitive diagnosis. Herein, we describe a case of a 46-year-old female presenting with intermittent left flank pain, upon which computed tomography demonstrated a retroperitoneal mass. Upon resection, histopathology revealed the mass to be a thin-walled cystic mass lined by ciliated columnar cells and cartilage, consistent with a subdiaphragmatic bronchogenic cyst. A comprehensive literature review of sBC was also performed.

    A retroperitoneal tumor originating from a bronchogenic cyst is an extreme rarity. We report the sixth case of a retroperitoneal bronchogenic cyst in an asymptomatic 38-year-old man who was initially admitted to hospital due to elective herniotomy of a right-sided inguinal hernia. Excluding symptomatic hernia by preoperative, routine-ultrasound we detected left-sided adrenal tumor mass. Computerized tomography and inconspicuous hormone-analysis completed preoperative evaluation. A tumor with 3 cm in diameter above the left adrenal gland, partly solid, partly cystic could be removed by laparotomy incision without complications. Final pathology confirmed diagnosis of a bronchogenic, dysontogenic cyst. Although rare, these cysts should be considered in differential-diagnosis of retroperitoneal tumors.

    Flexible transbronchial needle aspiration (TBNA) provides access to mediastinal lymph nodes, but its role in staging bronchogenic carcinoma is unknown. To determine the efficacy and safety of this procedure for staging the extent of mediastinal disease, the results of TBNA performed during fiberoptic bronchoscopy in 39 patients without known extrathoracic metastases were reviewed. Flexible TBNA was found to be a safe, effective method for determining the presence or absence of mediastinal metastases from bronchogenic carcinoma. Furthermore, TBNA results compare favorably with roentgenographic staging techniques, with the added advantage of providing cytopathologic information. PMID:6313305

    Computed tomography has become an important diagnostic modality in the preoperative staging of patients with bronchogenic carcinoma. The adrenal glands represent one of the most frequent sites of metastasis. Therefore, an isolated adrenal mass discovered on preoperative thoracoabdominal CT poses a diagnostic problem. Three hundred thirty patients with histologically proved nonsmall-cell bronchogenic carcinoma were evaluated. Thirty-two had adrenal masses without further evidence of disease in the abdomen, Eight of these 32 masses were metastases, 17 were proved adenomas, and 7 did not undergo biopsy. Thus an isolated adrenal mass is more likely benign than metastatic, and biopsy is advocated prior to withholding potentially curative surgery.

    Gastric bronchogenic cysts are rare lesions, first described in 1956, with only 34 cases reported in the literature to date. The present study described a case of bronchogenic cyst of the stomach in a 17-year-old female who presented with periodic epigastric pain. In addition, the study analyzed the existing literature on these lesions. Gastric bronchogenic cysts are more common in females (female:male ratio, 21:14) and the median age of their development is 43 years. In total, 48.57% of the 34 previously reported cases were identified incidentally, and the remainder presented mainly with epigastric pain. Cyst sizes varied between 1.7 and 15 cm. In 3 cases, preoperative diagnosis was performed using needle biopsy, whereas several studies were initially misdiagnosed as stromal tumors. In 85% of the cases (31/35), cyst resection was performed, with laparoscopy used in 4 of the cases. The findings of the present study and literature review suggested that bronchogenic cysts of the stomach are rare, and surgical resection is warranted to treat symptoms and prevent malignant transformation.

    What is the central question of this study? Do individuals with chronic obstructive pulmonary disease have blood flow through intrapulmonary arteriovenous anastomoses at rest or during exercise? What is the main finding and its importance? Individuals with chronic obstructive pulmonary disease have a greater prevalence of blood flow through intrapulmonary arteriovenous anastomoses at rest than age-matched control subjects. Given that the intrapulmonary arteriovenous anastomoses are large enough to permit venous emboli to pass into the arterial circulation, patients with chronic obstructive pulmonary disease and an elevated risk of thrombus formation may be at risk of intrapulmonary arteriovenous anastomosis-facilitated embolic injury (e.g. stroke or transient ischaemic attack). The pulmonary capillaries prevent stroke by filtering venous emboli from the circulation. Intrapulmonary arteriovenous anastomoses are large-diameter (≥50 μm) vascular connections in the lung that may compromise the integrity of the pulmonary capillary filter and have recently been linked to cryptogenic stroke and transient ischaemic attack. Prothrombotic populations, such as individuals with chronic obstructive pulmonary disease (COPD), may be at increased risk of stroke and transient ischaemic attack facilitated by intrapulmonary arteriovenous anastomoses, but the prevalence and degree of blood flow through intrapulmonary arteriovenous anastomoses in this population has not been fully examined and compared with age-matched healthy control subjects. We used saline contrast echocardiography to assess blood flow through intrapulmonary arteriovenous anastomoses at rest (n = 29 COPD and 19 control subjects) and during exercise (n = 10 COPD and 10 control subjects) in subjects with COPD and age-matched healthy control subjects. Blood flow through intrapulmonary arteriovenous anastomoses was detected in 23% of subjects with COPD at rest and was significantly higher compared with age

    A 24 year old male presented with a history of recurrent bronchopulmonal infections. Chest computed tomography was performed, revealing a right central mass. In the following bronchoscopy and ultrasound guided needle aspiration of the tumour no specific diagnosis could be obtained. Due to the central location of the tumour thoracotomy and middle lobe resection was performed. Histopathological analysis revealed an intrapulmonary, subpleural located Morbus Castleman of the hyaline-vascular type. Castleman’s disease is a very rare disorder of the lymphatic tissue that is differentiated into two clinical subtypes. The localized type presents histologically almost always as the hyaline-vascular form. Findings have been reported in mediastinal lymph nodes, the abdomen and peripheral lymphnodes. Intrapulmonary development is very rare and only 9 cases have previously been described in literature. On the other hand the multicentric type accounts for approximately 10%–15% of cases and histologically usually presents as the plasma cell variant. It is accompanied by fatigue and general weakness and often requires systemic steroid or chemotherapy. The localized type develops less clinical symptoms and is curable by complete surgical resection. PMID:26581496

    The prognosis of bronchogenic carcinoma depends on its histology and the time of its first diagnosis. The 5-year-survival rate after radiation treatment is 3-10%. It is much better for tumors detected and operated in an early stage, averaging 21%. The roentgenomorphology of central and peripheral bronchogenic carcinoma and the differential diagnosis is demonstrated on a selected group of 300 patients seen in the "Klinik und Poliklinik für Radiologie" in Munich between 1975 and 1979. In conclusion we think it not justified to hesitate performing bronchoscopy and/or percutaneous needle aspiration lung biopsy in cases of unclear peripheral or central pulmonary shadows, considering the low risks of the two procedures.

    An unusual case is presented of a tourist who developed fatal cerebral air embolism, pneumomediastinum and pneumopericardium while ascending from low altitude to Europe's highest railway station. Presumably the air embolism originated from rupture of the unsuspected bronchogenic cyst as a result of pressure changes during the ascent. Cerebral air embolism has been observed during surgery, in scuba diving accidents, submarine escapes and less frequently during exposure to very high altitude. People with known bronchogenic cysts should be informed about the risk of cerebral air embolism and surgical removal should be considered. Cerebral air embolism is a rare cause of coma and stroke in all activities with rapid air pressure changes, including alpine tourism, as our unfortunate tourist illustrates.

    We describe herein a rare case of a retroperitoneal bronchogenic cyst successfully treated by laparoscopic surgery. A 39-year-old man with low-grade fever was referred to our hospital because of suspicion of an adrenal tumor. Abdominal computerized tomography (CT) and ultrasonography revealed a homogenous solid mass, 35 x 30 mm in diameter, in the left suprarenal region. Laboratory studies showed that the levels of adrenal hormones were normal except for the white blood cell count of 9,700/microL and C-reactive protein of 1.7 mg/dl. We diagnosed it as a non-functioning adrenocortical adenoma or an adrenal cyst. However, one year later he underwent laparoscopic surgery because the mass had gradually increased by 10 mm and the low-grade fever persisted. Pathological evaluation of the surgical specimens established the diagnosis of retroperitoneal bronchogenic cyst. The low-grade fever disappeared after the surgery.

    A 62-year-old male who had gallbladder stone was admitted because of an abnormality in abdominal CT. Abdominal CT revealed the mass lesion with smooth margin under the diaphragmatic area, whose density was higher than that of water. Both MRI T1-weighted and T2-weighted images showed a relatively high intensity. On ultrasonography, the lesion was consisted of a thin wall. On the basis of these imaging modalities, the diagnosis was considered to be cyst. The mass was resected via posterior extraperitoneal approach, and its histologic diagnosis was bronchogenic cyst containing turbid fluid. Subdiaphragmatic bronchogenic cyst is rarely reported. The characteristic findings of MRI and ultrasonography was useful for the diagnosis of a cyst with turbid contents.

    Although bronchogenic cysts (BCs) are benign congenital malformations usually occur in thoracic cavity, retroperitoneal location is extremely uncommon. We reported a case of BC occurred in the retroperitoneum, which was excised laparoscopically. A 64-year-old Japanese woman was admitted to the hospital because of submucosal tumor in the upper part of the stomach. An upper gastrointestinal endoscopy revealed a submucosal tumor located just distal to the esophagogastric junction. The abdominal computed tomography scan revealed a cystic mass located in contact with lesser curvature of the stomach and the dorsal surface of the liver. As the cystic mass was well-circumscribed and showed no positive findings suggestive of malignancy, the laparoscopic excision of the cystic mass was performed. The cystic tumor was completely excised with a laparoscopic procedure. The histologic findings indicated that the cyst was surfaced by the ciliated pseudostratified epithelium without the presence of the cartilage, which was compatible with the BC of the retroperitoneum. This case highlights the safety and the feasibility of complete laparoscopic excision of retroperitoneal BC. Laparoscopic excision of retroperitoneal BC definitely provides all advantages of minimally invasive procedure, which improves postoperative patient discomfort and pain and shortens hospital stay. Laparoscopic procedure may definitely be a standard approach for the excision of retroperitoneal BC.

The SFT reported here is an extremely rare phenotype in two respects: it originated in a child under age 10 years, and it expanded in an intrapulmonary fashion.

  3. The effects of dobutamine and dopamine on intrapulmonary shunt and gas exchange in healthy humans

    The development of intrapulmonary shunts with increased cardiac output during exercise in healthy humans has been reported in several recent studies, but mechanisms governing their recruitment remain unclear. Dobutamine and dopamine are inotropes commonly used to augment cardiac output; however, both can increase venous admixture/shunt fraction (Qs/Qt). It is possible that, as with exercise, intrapulmonary shunts are recruited with increased cardiac output during dobutamine and/or dopamine infusion that may contribute to the observed increase in Qs/Qt. The purpose of this study was to examine how dobutamine and dopamine affect intrapulmonary shunt and gas exchange. Nine resting healthy subjects received serial infusions of dobutamine and dopamine at incremental doses under normoxic and hyperoxic (inspired O2 fraction = 1.0) conditions. At each step, alveolar-to-arterial Po2 difference (A-aDo2) and Qs/Qt were calculated from arterial blood gas samples, intrapulmonary shunt was evaluated using contrast echocardiography, and cardiac output was calculated by Doppler echocardiography. Both dobutamine and dopamine increased cardiac output and Qs/Qt. Intrapulmonary shunt developed in most subjects with both drugs and paralleled the increase in Qs/Qt. A-aDo2 was unchanged due to a concurrent rise in mixed venous oxygen content. Hyperoxia consistently eliminated intrapulmonary shunt. These findings contribute to our present understanding of the mechanisms governing recruitment of these intrapulmonary shunts as well as their impact on gas exchange. In addition, given the deleterious effect on Qs/Qt and the risk of neurological complications with intrapulmonary shunts, these findings could have important implications for use of dobutamine and dopamine in the clinical setting.

Intrapulmonary aerosol delivery of isoniazid, capreomycin, and amikacin to mice with pulmonary infection of Mycobacterium tuberculosis demonstrated efficacy in reducing pulmonary bacterial loads similar to that seen by standard drug delivery methods, even when lower concentrations of drugs and fewer doses were used in the aerosolized drug regimens. Interestingly, intrapulmonary delivery of isoniazid also reduced the bacterial load in the spleen. PMID:22547626

    The pharmacokinetic and pharmacodynamic efficacy of intrapulmonary administration of ciprofloxacin (CPFX) for the treatment of respiratory infections caused by pathogenic microorganisms resisting sterilization systems of alveolar macrophages (AMs) was evaluated by comparison with an oral administration. The time-courses of the concentration of CPFX in AMs and lung epithelial lining fluid (ELF) following intrapulmonary administration of CPFX solution to rats (200 microg/kg) were markedly higher than that following oral administration (10 mg/kg). The time-course of the concentrations of CPFX in plasma following intrapulmonary administration was markedly lower than that in AMs and ELF. These results indicate that intrapulmonary administration is more effective in delivering CPFX to AMs and ELF, compared with oral administration, in spite of a low dose and it avoids distribution of CPFX to the blood. In addition, the antibacterial effects of CPFX in AMs and ELF following intrapulmonary administration were evaluated by pharmacokinetics/pharmacodynamics analysis. The concentration of CPFX in AMs and ELF-time curve (AUC)/minimum inhibitory concentration of CPFX (MIC) ratio and the maximum concentration of CPFX in AMs and ELF (Cmax)/MIC ratio were markedly higher than the effective values. The present study indicates that intrapulmonary administration of CPFX is an effective technique for the treatment of respiratory infections.

We performed laparoscopic surgery in order to relieve the symptoms and make a diagnosis. Because there was adhesion between the mass and gastric wall, the mass was resected together with the gastric wall. Histopathological findings revealed the cyst with ciliated columunar epithelium and the final diagnosis was retroperitoneal bronchogenic cyst. There was no evidence of malignancy and the back pain disappeared.

    The effects of interferons on the radiosensitivity of in vitro human bronchogenic carcinoma cells was investigated. Human fibroblast-derived interferon (IFN-beta) was found to sensitize cells to gamma irradiation while either HuIFN-alpha or mouse IFN-alpha/beta did not. The observed radiosensitization was supra-additive and resulted in a decrease in the shoulder width of the radiation dose-cell survival curve but did not affect the slope. The degree of radiosensitization of the various IFNs tested paralleled the antiproliferative effects of these IFNs on this cell line.

    2015-02-01

    Laboratory and field investigations have demonstrated that intrapulmonary arteriovenous anastomoses (IPAVA) may provide an additional means for venous gas emboli (VGE) to cross over to the arterial circulation due to their larger diameter compared to pulmonary microcirculation. Once thought to be the primary cause of decompression sickness (DCS), it has been demonstrated that, even in large quantities, their presence does not always result in injury. Normally, VGE are trapped in the site of gas exchange in the lungs and eliminated via diffusion. When VGE crossover takes place in arterial circulation, they have the potential to cause more harm as they are redistributed to the brain, spinal column, and other sensitive tissues. The patent foramen ovale (PFO) was once thought to be the only risk factor for an increase in arterialization; however, IPAVAs represent another pathway for this crossover to occur. The opening of IPAVAs is associated with exercise and hypoxic gas mixtures, both of which divers may encounter. The goal of this review is to describe how IPAVAs may impact diving physiology, specifically during decompression, and what this means for the individual diver as well as the future of commercial and recreational diving. Future research must continue on the relationship between IPAVAs and the environmental and physiological circumstances that lead to their opening and closing, as well as how they may contribute to diving injuries such as DCS.

    Abdominal bronchogenic cysts are very rare with less than 20 published cases. We report the case of a retroperitoneal bronchogenic cyst in a 12-year-old boy, who initially presented with a primitive neuroectodermal tumor of the pelvis. Computed tomography (CT) showed a small, hyperdense nonenhancing mass adjacent to the right crus of the diaphragm. Follow-up CT after chemotherapy showed a decrease in CT attenuation of this mass, but a slight increase in size. At surgery the mass was loosely attached to the diaphragm and final pathology confirmed the diagnosis of a bronchogenic cyst.

    A large cystic mass was found in the subdiaphragmatic region of a 46-year-old woman who had complained of continuous pain in the left flank . The cyst was located in the retroperitoneum just below the diaphragm and was adhered to the diaphragmatic skeletal muscle and abdominal aorta, but was separate from the spleen, pancreas, left adrenal gland and left kidney. The surgically resected cyst measured 8 x 8 x 7 cm and was filled with protein-rich fluid, which contained amylase and embryonal proteins such as carcinoembryonic antigen, CA125 and CA19-9. Histologically, the cyst wall was composed of a fibrovascular connective tissue containing thin smooth muscle layers and mucus-secreting glands and was lined by a ciliated pseudostratified or tall columnar epithelium without dysplastic changes. Thus, a diagnosis of bronchogenic cyst, which is usually discovered in the posterior part of the mediastinum, was made. A rare case of bronchogenic cyst and a literature review is presented.

    We report a rare case of a subdiaphragmatic cyst, diagnosed prenatally during routine ultrasound screening at 25 weeks' gestation. Serial ultrasonographic evaluation demonstrated a slight increase in the size of the cyst during pregnancy. On the basis of the anatomic site and the sonographic features of the lesion, four diagnostic hypotheses were postulated: cystic neuroblastoma, adrenal hemorrhage, duplication of the inferior third of the esophagus and retroperitoneal cystic lymphangioma. A healthy baby, weighing 3300 g and with Apgar scores of 8 and 9, was delivered vaginally at term. He underwent successful surgery at the age of 3 months. The post-operative course was uneventful and the baby is currently doing well. Histology revealed a bronchogenic cyst.

The cyst was located in the retroperitoneum just below the diaphragm and was adhered to the left crus of diaphragm and unconnected with any other structures. The surgically resected cyst was 50 x 25 x 22 mm diameter and the wall was thin and contained white turbid mucus. Histologically, the cyst consisted of ciliated epithelium, mucus glands, smooth muscle, cartilage and this evidence established the final diagnosis of bronchogenic cyst. The post operative course was uneventful and the patient was discharged 10 days after operation. This is the 4th reported case of a subdiaphragmatic bronchogenic cyst in the Japanese literature.

    This unusual clinical case adds itself to the limited list of existing reports of retroperitoneal bronchogenic cysts in the international literature. It emphasizes the difficulties encountered in making a preoperative diagnosis, since these lesions can be described as both solid and cystic masses. A 69-year-old man underwent surgery to remove an expanding mass diagnosed as originating in the adrenal gland and discovered during clinical investigation for other indications. The lesion was excised only after adrenalectomy whereupon its cystic nature was revealed. Retroperitoneal bronchogenic cysts, though rare, should be considered in the differential diagnosis of retroperitoneal expanding lesions, especially in the presence of cystic tumours of the left adrenal region. This is the first case of a retroperitoneal bronchogenic cyst reported in an adult in Italy.

    Cardiac metastases in bronchogenic carcinoma may occur due to retrograde lymphatic spread or by hematogenous dissemination of tumour cells, but direct invasion of heart by adjacent malignant lung mass is very uncommon. Pericardium is frequently involved in direct cardiac invasion by adjacent lung cancer. Pericardial effusion, pericarditis, and tamponade are common and life threatening presentation in such cases. But direct invasion of myocardium and endocardium is very uncommon. Left atrial endocardium is most commonly involved in such cases due to anatomical contiguity with pulmonary hilum through pulmonary veins, and in most cases left atrial involvement is asymptomatic. But myocardial compression and invasion by adjacent lung mass may result in myocardial ischemia and may present with retrosternal, oppressive chest pain which clinically may simulate with the acute myocardial infarction (AMI). As a result, it leads to misdiagnosis and delayed diagnosis of lung cancer. Here we report a case of non-small-cell carcinoma of right lung which was presented with asymptomatic invasion in left atrium and retrosternal chest pain simulating AMI due to myocardial compression by adjacent lung mass, in a seventy-four-year-old male smoker.

    One hundred ten patients with proved bronchogenic carcinoma who were undergoing computed tomography (CT) of the thorax also underwent CT of the adrenals to determine the value of routine preoperative assessement of this gland. Sixteen adrenal masses were found in 11 patients. In five patients the adrenals were the only site of metastasis. CT of the adrenals should be performed routinely when the thorax is examined pre-operatively in patients with non-oat-cell bronchogenic carcinoma to improve patient selection for thoractomy.

    We report a very rare case of a bronchogenic cyst combined with nontuberculous mycobacterial pulmonary disease in an immunocompetent patient. A 21-year-old male was referred to our institution because of a cough, fever, and worsening of abnormalities on his chest radiograph, despite anti-tuberculosis treatment. Computed tomography of the chest showed a large multi-cystic mass over the right-upper lobe. Pathological examination of the excised lobe showed a bronchogenic cyst combined with a destructive cavitary lesion with granulomatous inflammation. Microbiological culture of sputum and lung tissue yielded Mycobacterium avium. The patient was administered anti-mycobacterial treatment that included clarithromycin. PMID:23346002

    Bronchogenic cysts are developmental abnormalities of the primitive foregut resulting from aberrant budding from the ventral diverticulum. A retroperitoneal position for a bronchial cyst is extremely unusual and should be differentiated from other neoplastic lesions. Although histologically they can be differentiated from other lesions, bronchial cysts may show various pathological patterns of differentiation that may cause confusion in differentiating them from cystic teratomas. This is a case of a retroperitoneal bronchogenic cyst featuring uncommon histological findings, which raises the question whether these benign lesions can always be accurately differentiated from teratomatoid cystic neoplasms.

    Although solitary fibrous tumors (SFTs) of the pleura are not uncommon, intrapulmonary SFTs are extremely rare. A 72-year-old woman was admitted to our hospital for an investigation of an enlarging intrapulmonary tumor. Because a definitive diagnosis could not be readily established, a pulmonary wedge resection under video-assisted thoracic surgery was performed. Grossly, the tumor was white, well circumscribed, and separate from the pleural surface. Histologically, it consisted of spindle cells proliferating in a vague fascicular pattern, with many dilated capillaries, and intermingled glandular components. These findings suggested a differential diagnosis that included SFT and nonchondromatous pulmonary hamartoma. On immunohistochemical analysis, the spindle cells showed a strong positive reaction to the CD34 antigen. Interphase fluorescent in situ hybridization revealed an absence of HMGA-1 and -2 translocations. These results supported a diagnosis of SFT. A genetic approach may therefore be useful in the differentiation of SFT from nonchondromatous hamartoma.

  5. Regulation of vascular tone by UTP and UDP in isolated rat intrapulmonary arteries.

    Vasoconstrictor and vasodilator responses of isolated rat intrapulmonary arteries to the pyrimidine nucleotides UTP and UDP were evaluated and compared with vascular responses to ATP and its analogues. UTP and UDP (1-500 microM) were equipotent in inducing concentration-dependent vasoconstriction, unaffected by the P2 receptor antagonists suramin (100 microM) and Reactive blue 2 (50 microM); ATP (10-500 microM) produced weaker vasoconstriction. UTP and UDP lacked vasodilator activity, while ATP and its analogue 2-methylthio ATP evoked endothelium-dependent vasodilatation. These results indicate that UTP and UDP evoke vasoconstriction of rat intrapulmonary arteries whereas ATP is predominantly a vasodilator at the same arteries. Furthermore, the pharmacological profile of the native UTP/UDP receptor differs from that of the known P2Y2, P2Y4 and P2Y6 recombinant receptors for pyrimidine nucleotides.

    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.

    Intrapulmonary haematomas occurred during mechanical ventilation of two patients with advanced chronic obstructive pulmonary disease and bullous dystrophy. In both cases, the haematomas were revealed by blood-stained aspirates, a fall in haemoglobin level, and the appearance of radiological opacities. Haematoma occurrence in the area of a bulla which recently has rapidly increased in size, suggests that the haematoma is due to the rupture of stretched vessels embedded in the wall of the bulla.

    Using serial perfusion lung scans, the opening up and closure of right-to-left intrapulmonary arteriovenous shunts has been documented over a period of several weeks in a patient with chronic alcoholic liver disease. The presence of the shunts correlates well with the severity of hypoxemia and the presence of nodular mottling on chest radiographs. The time course of these changes with clinical status suggests lability and the functional nature of these shunts.

    Lung injury following deposition of IgG immune complexes is neutrophil-dependent and requires both tumor necrosis factor alpha (TNF alpha) and CD18. In the current studies, we have evaluated the relationship between TNF alpha and expression of intracellular adhesion molecule-1 (ICAM-1) in vitro and in vivo. In both rat pulmonary artery endothelial cells and human umbilical vein endothelial cells, TNF alpha induced an early (within 60 minutes) increase in ICAM-1 expression, followed by a peak at 6 to 8 hours, with relatively stable expression at 24 hours. Expression of E-selectin did not show the early phase (within 60 minutes) of up-regulation, peaked at 4 hours, and then declined thereafter. Using a radioimmunochemical assay in vivo, it was demonstrated that intrapulmonary deposition of IgG immune complexes caused a progressive increase in ICAM-1 expression in lung over an 8-hour period. In animals pretreated with antibody to TNF alpha, the intrapulmonary expression of ICAM-1 was significantly reduced. These results were confirmed by immunoperoxidase analysis of lung tissue. It was also shown that airway instillation of TNF alpha caused up-regulation of ICAM-1 in lung. These data support the concept that deposition of IgG immune complexes in lung induces intrapulmonary up-regulation of ICAM-1 in a manner that is TNF alpha-dependent.

    Bronchogenic cyst is a rare developmental lesion. It is usually asymptomatic and most frequently located in the middle mediastinum and lung parenchyma. It can cause symptoms only when infected or pressing on neighboring structures. The MRI findings in a 34-year-old woman with an 8 months history of back pain were evaluated and revealed a cystic lesion in the left paravertebral area. The histopathologic evaluation of the material aspirated with CT guidance was reported to be bronchogenic cyst. A simultaneous alcohol ablation was accomplished. After the procedure the patient's pain disappeared and the follow-up MRI scan 1 year later revealed no relapse. Paravertebrally located bronchogenic cysts are very rare and only 3 cases were found to be reported in the medical literature prior to this one. While aspiration alone is sufficient for diagnosis, it is insufficient to treat the lesion and prevent the recurrences. This paper reports a paravertebral bronchogenic cyst which was symptomatic despite of its small size. CT-guided aspiration was accomplished and simultaneous alcohol ablation was carried out to prevent recurrences.

    Bronchogenic cyst is a rare clinical; entity that occurs due to an anomalous development of the ventral foregut; they are usually single but may be multiple and can be filled with fluid or mucus. They have been found all along the transoesophageal course, in perihilar or intraparenchymal sites, with predilection for the area around the carina. The location of the cyst depends on the embryonic stage of development at which the anomaly occurs. When the abnormal budding occurs during the early development, the cyst tends to be located along the tracheobronchial tree. The cysts that develop later during the late development are more peripheral and may be located within the lung parenchyma. Bronchogenic cysts have also been described in more remote locations, including neck, interatrial septum, abdomen, and retroperitoneal space. Past reports emphasised that a bronchogenic cyst is usually asymptomatic and presents as an incidental finding, but more recent reports suggest that the majority of adults with bronchogenic cysts ultimately become symptomatic. The actual natural history and percentage of asymptomatic bronchogenic cyst in adults are not known because of the absence of long-term follow up of a large group of patients with asymptomatic cyst. Symptomatic patients usually present with symptomatic related to cyst infection or compression of adjacent structures. Presentation in the elderly population is quite rare. It has been reported that approximately 0.6% of such cyst are noted in patients above the age of 60 years. Total documented cases of patients presenting after the age of 70 years have been noted to be only 8 in 2002.

    Congenital myopathies are a heterogeneous group of inherited muscle disorders, characterized by the predominance of particular histopathological features on muscle biopsy, such as cores (central core disease) or rods (nemaline myopathy). Clinically, early onset of the disease, stable or slowly progressive muscle weakness, hypotonia and delayed motor development are common in most forms. As a result, the diagnosis of a subtype of congenital myopathy is largely based on the presence of specific structural abnormalities in the skeletal muscle detected by enzyme-histochemistry and electron microscopy studies. During the last decades there have been significant advances in the identification of the genetic basis of most congenital myopathies. However, there is significant genetic heterogeneity within the main groups of congenital myopathies, and mutations in one particular gene may also cause diverse clinical and morphological phenotypes. Thus, the nosography and nosology in this field is still evolving. PMID:23622357

    For infants born with respiratory distress syndrome (RDS), liquid bolus delivery of surfactant administered through an endotracheal tube is common practice. While this method is generally effective, complications such as transient hypoxia, hypercapnia, and altered cerebral blood flow may occur. Aerosolized surfactant therapy has been explored as an alternative. Unfortunately, past efforts have led to disappointing results as aerosols were generated outside the lungs with significant pharyngeal deposition and minimal intrapulmonary instillation. A novel aerosol generator (Microjet™) is evaluated herein for intrapulmonary aerosol generation within an endotracheal tube and tested with Curosurf and Infasurf surfactants. Compared with other aerosol delivery devices, this process utilizes low air flow (range 0.01-0.2 L/min) that is ideal for limiting potential barotrauma to the premature newborn lung. The mass mean diameter (MMD) of the particles for both tested surfactants was less than 4 μm, which is ideal for both uniform and distal lung delivery. As an indicator of phospholipid function, surfactant surface tension was measured before and after aerosol formation; with no significant difference. Moreover, this device has an outside diameter of <1mm, which permits insertion into an endotracheal tube (of even 2.0 mm). In the premature infant where intravenous access is either technically challenging or difficult, aerosol drug delivery may provide an alternative route in patient resuscitation, stabilization and care. Other potential applications of this type of device include the delivery of nutrients, antibiotics, and analgesics via the pulmonary route. PMID:26884641

    We measured the ventilatory response of anesthetized, unidirectionally ventilated pigeons and burrowing owls to changes in intrapulmonary CO2 concentration and the static CO2 sensitivity of intrapulmonary chemoreceptors (IPC) in these species and the domestic goose. Compared with pigeons, burrowing owls showed a significantly reduced respiratory frequency and amplitude response to increases in FICO2 from 0.05 to 0.10, which corroborates similar findings in intact, awake individuals of the same species. The average static CO2 sensitivity of IPC in geese, pigeons, and burrowing owls, as reflected by the average slope of the linear regressions of receptor discharge frequency on ln(PICO2), was -7.96, -11.1 and -6.87 imp/sec . ln(PICO2), respectively. The sensitivities of individual receptors were normally distributed in geese and pigeons, but skewed in burrowing owls. Therefore, the median CO2 sensitivity [-5.50 imp/sec . ln(PICO2)] is a more appropriate measure of the typical CO2 sensitivity of IPC in burrowing owls. The static CO2 sensitivity of IPC in burrowing owls is the lowest reported for euthermic birds with a normal acid-base balance and may materially contribute to the blunted ventilatory response of these birds to the elevated CO2 levels they encounter in nature.

    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.

    A 5-½-month-old female Holstein-Friesian calf was presented with a history of recurring ruminal tympany and poor development. The absence of lung sounds on the right hemithorax suggested a right-sided intrathoracic pathology. Radiography and computed tomography revealed a large thin-walled cavernous lesion with a gas-fluid interface which almost completely filled the right thoracic cavity. Fluid aspirated from the lesion was clear, yellowish and odorless. These findings led to the diagnosis of a bronchogenic cyst. Thoracotomy was performed under general anesthesia. The cyst strongly adhered to the adjacent lung tissue. After removal of the free wall, the adjacent lung tissue was sealed using surgical stapling instruments, and the non-removable part of the wall was curetted and rinsed. The intensive postoperative management included antibiotic therapy, oxygen supplementation and regional lidocaine infusion. Anti-inflammatory drugs were administered for further pain control. The calf recovered well and was released from the clinic on postoperative day 11. Intra- or extrathoracic bronchogenic cysts result from abnormal budding during the embryonic development of the tracheobronchial system. Successful treatment of this calf despite the size of the lesion and the invasive character of the surgical intervention indicates that resection of bronchogenic cysts in cattle may be an option for valuable 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." PMID:25726292

    Esophageal bronchogenic cysts are extremely rare. Here we report a more rare type of both presence of intra- and paraesophageal bronchogenic cyst that was safely removed via surgical resection. A 31-year-old male patient with space-occupying lesions in the mediastinum suddenly presented with persistent chest pain for 2 days and then transferred to dysphagia >1 week. Preoperative diagnosis is difficult. Endoscopic ultrasonography (EUS) showed a hypoechoic cystic-solid mass arising from the muscularis propria and local hyperechoic area in the deeper portion of cyst, concomitant with a heterogeneous center and tube-like structure lesion in mediastinum. Turbid coffee color paste contents were aspirated inside the tumor under endoscopic ultrasonography guided-fine needle aspiration (EUS-FNA). A subsequent surgery was performed and histologic finding was diagnostic of esophageal bronchogenic cyst. Immunohistochemical staining confirmed the cyst was positive for carbohydrate antigen 199 (CA199) and carbohydrate antigen 125 (CA125). At a follow-up visit 3 months later, the patient had a regular diet and no complaint. This study is to summarize the clinical manifestations and EUS features of esophageal bronchogenic cyst by retrospectively reviewing the literature and simultaneously to provide guide for the correct examination scheme. The appearance of esophageal bronchogenic cyst can be great variation; EUS seems to be a valuable option for diagnosis and surveillance. PMID:26986156

    Solitary fibrous tumor (SFT) is a ubiquitous neoplasm that arises most commonly from the pleura. SFT arising within lung parenchyma (intrapulmonary SFT) has been rarely reported and is therefore not well recognized. We present a clinicopathologic and immunohistochemical study of 24 cases of primary intrapulmonary SFT. Patients' ages ranged from 44 to 83 years (mean, 58 y). None of the patients had evidence or history of a similar tumor elsewhere. Tumor size ranged from 2.3 to 22 cm (mean, 8.5 cm). On the basis of the degree of cytologic atypia, cellularity, mitotic activity, and areas of necrosis, the lesions were divided into low-grade, intermediate-grade, and high-grade histology. Twenty-one tumors showed the conventional features of SFT of low-grade histology (<5 mitoses per 10 high-power fields), with alternating bands of rope-like collagen flanked by a bland-appearing spindle cell proliferation. Hemangiopericytic, angiofibromatous, and a neural-like plexiform growth pattern were also observed. Five of 21 cases showed an "adenofibromatous" appearance imparted by entrapped normal airspaces at the advancing edges of the lesion. One intermediate-grade tumor showed overall increased cellularity with plump, pleomorphic nuclei, 5 to 10 mitoses per 10 high-power fields, and focal areas of classic SFT. Two cases showed high-grade features at initial presentation, with areas resembling a pleomorphic high-grade sarcoma admixed with foci of conventional, low-grade SFT. Immunohistochemical staining analyses performed in 13 cases showed positivity of the tumor cells for CD34, bcl-2, and CD99 in the majority of cases tested. Clinical follow-up was available in 18 patients, with long-term follow-up (>5 y) in 6. Fourteen (14/18) patients were alive and well without evidence of disease 1 month to 14 years after initial diagnosis. Three patients died of their tumors after 4, 5, and 7 years; in 2 of them the initial tumor was of low-grade histology, but the recurrence

    Intrapulmonary percussive ventilation (IPV) is a novel form of chest physiotherapy delivered by a percussive pneumatic device (IPV, Percussionaire, Sand Point, ID). There are few published reports about the use of IPV for diseases other than cystic fibrosis. We report our experience with three pediatric patients and one adult patient with persistent pulmonary consolidation refractory to conventional therapies. Three of the four patients had neuromuscular disease; one patient had segmental atelectasis due to aspiration. Three of the four patients showed clinical and radiographic improvement within 48 hours of starting IPV. The fourth patient experienced brief episodes of third-degree atrioventricular block, hypoxemia, and bradycardia during two IPV treatments. IPV was safely restarted and he slowly improved. We conclude that while IPV requires further clinical evaluation, it appears to be a safe and effective therapy for selected patients. However, close observation is essential during and after IPV treatments, especially in patients who have difficulty mobilizing or expectorating sputum.

    Tilmicosin (TIM, Pulmotil) was administered to eight rabbits by oral gavage at a dose of 12.5 mg/kg body weight for 2, 5, and 7 days, and its plasma kinetics and intrapulmonary disposition were investigated. TIM concentrations in plasma samples collected after days 1 and 6 of treatment were measured by high-performance liquid chromatography with ultraviolet detection. The pharmacokinetic parameters, obtained by non-compartmental analysis of TIM plasma concentrations, did not show any significant variations between days 1 and 6. From the second day of treatment, TIM concentrations attained in lung tissue and pulmonary alveolar macrophages (PAM) exceeded those in plasma by 7- and 400-fold, respectively, and high levels were maintained in lung tissues during the entire treatment duration. After the first day of withdrawal, a fast decline in TIM levels in both plasma and lung tissue was observed, but in PAM, much higher concentrations were maintained after 3 days of TIM withdrawal.

    In 12 anesthetized paralyzed dogs, pulmonary gas exchange and intrapulmonary inspired gas distribution were compared between continuous-flow ventilation (CFV) and conventional mechanical ventilation (CMV). Nine dogs were studied while they were lying supine, and three dogs were studied while they were lying prone. A single-lumen catheter for tracheal insufflation and a double-lumen catheter for bilateral endobronchial insufflation (inspired O2 fraction = 0.4; inspired minute ventilation = 1.7 +/- 0.3 (SD) 1.kg-1.min-1) were evaluated. Intrapulmonary gas distribution was assessed from regional 133Xe clearances. In dogs lying supine, CO2 elimination was more efficient with endobronchial insufflation than with tracheal insufflation, but the alveolar-arterial O2 partial pressure difference was larger during CFV than during CMV, regardless of the type of insufflation. By contrast, endobronchial insufflation maintained both arterial PCO2 and alveolar-arterial O2 partial pressure difference at significantly lower levels in dogs lying prone than in dogs lying supine. In dogs lying supine, the dependent lung was preferentially ventilated during CMV but not during CFV. In dogs lying prone, gas distribution was uniform with both modes of ventilation. The alveolar-arterial O2 partial pressure difference during CFV in dogs lying supine was negatively correlated with the reduced ventilation of the dependent lung, which suggests that increased ventilation-perfusion mismatching was responsible for the increase in alveolar-arterial O2 partial pressure difference. The more efficient oxygenation during CFV in dogs lying prone suggests a more efficient matching of ventilation to perfusion, presumably because the distribution of blood flow is also nearly uniform.

    There are several types of hydrocephalus, which are characterized based on the location of the cerebrospinal fluid (CSF) accumulation. Physical features of animals with congenital hydrocephalus may include a dome-shaped skull, persistent fontanelle, and bilateral ventrolateral strabismus. 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.

    Aniridia is a rare congenital, hereditary, bilateral disease which is associated with various systemic and ocular defects. We present the case of a 61 year old patient who was admitted in the hospital of ophthalmology Cluj Napoca, for the symptoms caused by the ocular defects associated with aniridia. In this case, aniridia is autosomal dominant transmitted with incomplete penetrance and it is not accompanied by any systemic defects. The disease also affects three of her sons and two nephews of the patient.

    Congenital hypoaldosteronism due to an isolated aldosterone biosynthesis defect is rare. We report a 4 month old female infant who presented with failure to thrive, persistent hyponatremia and hyperkalemia. Investigations revealed normal serum 17 hydroxy progesterone and cortisol. A decreased serum aldosterone and serum 18 hydroxy corticosterone levels with a low 18 hydroxy corticosterone: aldosterone ratio was suggestive of corticosterone methyl oxidase type I deficiency. She was started on fludrocortisone replacement therapy with a subsequent normalization of electrolytes. Further molecular analysis is needed to ascertain the precise nature of the mutation.

    A 63 year old woman presenting chronic back pain and neuralgia had abnormal shadow on chest radiograph. She has a history of pulmonary tuberculosis treated in 1977. The chest-CT scan showed a soft tissue mass in the lower lobe of the right lung and a cystic mass in the paravertebral region. The patient had right lower lobectomy and complete excision of a paraoesophageal cyst. Both masses were bronchogenic cysts at histology. The patient had an uneventful discharge the seventh postoperative day. After 4 years and 7 months of follow-up with CT-scann, the patient was free of symptoms with no evidence of recurrent disease.

    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.

    Paradoxical arterializations of venous gas emboli can lead to neurological damage after diving with compressed air. Recently, significant exercise-induced intrapulmonary anatomical shunts have been reported in healthy humans that result in widening of alveolar-to-arterial oxygen gradient. The aim of this study was to examine whether intrapulmonary shunts can be found following strenuous exercise after diving and, if so, whether exercise should be avoided during that period. Eleven healthy, military male divers performed an open-sea dive to 30 m breathing air, remaining at pressure for 30 min. During the bottom phase of the dive, subjects performed mild exercise at approximately 30% of their maximal oxygen uptake. The ascent rate was 9 m/min. Each diver performed graded upright cycle ergometry up to 80% of the maximal oxygen uptake 40 min after the dive. Monitoring of venous gas emboli was performed in both the right and left heart with an ultrasonic scanner every 20 min for 60 min after reaching the surface pressure during supine rest and following two coughs. The diving profile used in this study produced significant amounts of venous bubbles. No evidence of intrapulmonary shunting was found in any subject during either supine resting posture or any exercise grade. Also, short strenuous exercise after the dive did not result in delayed-onset decompression sickness in any subject, but studies with a greater number of participants are needed to confirm whether divers should be allowed to exercise after diving.

    Using an experimental model of acute pancreatitis in the rat, we have studied changes in the biophysical properties of lungs and intrapulmonary fibrin deposition in this condition. Acute pancreatitis is associated with a significant decrease in pulmonary compliance (p less than 0.01) and a significant increase in lung weight (p less than 0.01) compared with a control sham operation group. These changes are associated with a 24% increase in intrapulmonary 125I fibrinogen deposition (p less than 0.01), and an 18% increase in 125I fibrinogen deposition per gram of lung tissue (p less than 0.05) in acute pancreatitis, compared with a control sham operation group. The increased fibrinogen deposition is abolished by treatment with low dose heparin. Using the same animal model changes in pulmonary ultrastructure are shown using scanning electron microscopy. The results indicate that pulmonary abnormalities are associated with intrapulmonary fibrin deposition in experimental acute pancreatitis and these findings may be relevant to the well described respiratory complications of the condition in man.

    The authors report the case of a 40-year-old man who has presented for many years an intermittent progressive spastic paraplegia. Plain films of the spine show very important dysraphic abnormalities of the inferior dorsal column and the myelography shows a complete block suggesting an intramedullary space-occupying lesion at four levels above the vertebral abnormalities. The operation permits a total removal of an intramedullary "bronchogenic cyst". In the post-operative course, the neurologic deficit improves, six months later a spastic paraparesia remains. The review of the literature shows that this is an exceptional observation. Intramedullary bronchogenic cysts must be regarded as similar to intramedullary enterogenic cysts. They are not teratomas but dysembryoplasiae due to failure of the ento-ectoblastic separation between the second and the third weeks of life. These cysts form a part of the "ento-ectodermal adhesion syndrome" of Prob et al. The preoperative diagnosis is possible on the association of intermittent progressive syndrome of medullary compression and dysraphic spondylotic changes. The total surgical removal of the cyst, by micro-surgical techniques, is able to preserve the neurologic evolution with an excellent result if the operation is performed before definitive neurologic deficits occur.

    A follow-up (18)F-fluorodeoxyglucose ((18)F-FDG) PET/CT scan of a 57-year-old asymptomatic male who had undergone total thyroidectomy for thyroid cancer revealed a 5.0 × 4.0-cm, well-defined, ovoid-shaped mass around the left adrenal gland without definite FDG uptake. On the adrenal CT scan, the left paraadrenal tumor showed high attenuation on the precontrast scan without enhancement. The average Hounsfield unit (HU) was 58.1 on the precontrast scan and 58.4 on the postcontrast scan. The patient underwent laparoscopic adrenalectomy for resection of the left paraadrenal tumor. The final histopathologic examination revealed a bronchogenic cyst. Although retroperitoneal bronchogenic cysts are rare, they should be considered in the differential diagnosis of retroperitoneal cystic tumors. The preoperative diagnosis is difficult, but a contrast-enhanced CT scan or (18)F-FDG PET/CT scan may be useful for differentiating hyperattenuated cysts from other soft tissue masses.

    Biological rates in small animals are usually higher than those in large animals, yet the maximal rate of action potential (spike) generation in sensory neurons encoding rate functions is similar in all animals, due to the conserved genetics of voltage-gated ion channels. Therefore, sensory signals that vary at rates approaching maximal spike generation rate, as might occur in animals of diminished body size, may require specialized spike coding to convey this information. To test whether spike coding scales allometrically in sensory neurons monitoring signals that change frequency with body size, we recorded action potentials from 70 avian intrapulmonary chemoreceptors (IPC), respiratory neurons that detect lung CO2 changes during breathing, in five different avian species ranging in size from body mass Mb=0.045 kg (lovebirds) to 5.23 kg (geese). Since breathing frequency scales approximately to Mb-1/4 (higher in small birds, lower in large birds), we reasoned that IPC discharge frequencies may also scale to maintain spike information transmission within each breath. We found that phasic action potential discharge pattern, as quantified by the peak discharge rate and the magnitude of spike frequency adaptation, scaled between Mb-0.22 and Mb-0.26, like breathing rate (P<0.05). Previously published values of peak discharge rate in IPC also fit this allometric relationship. We suggest that mass-dependent scaling of neural coding may be necessary for preserving information transmission with decreasing body size. PMID:16081605

    The intrapulmonary pharmacokinetics of oral azithromycin were studied in 25 healthy volunteers, each of whom received an initial dose of 500 mg and then 250 mg once daily for four additional doses. Bronchoscopy, bronchoalveolar lavage, and venipuncture were performed 4, 28, 76, 124, 172, 244, 340, and 508 h after the first dose was administered. Azithromycin concentrations in epithelial lining fluid (ELF), alveolar macrophages, peripheral blood monocytes, and serum were measured by high-performance liquid chromatography. Azithromycin was extensively concentrated in cells and ELF. Drug concentrations in AMs (peak mean +/- standard deviation, 464 +/- 65 micrograms/ml) exceeded 80 micrograms/ml up to 508 h (21 days) following the first dose, while concentrations in PBMs (peak, 124 +/- 28 micrograms/ml) exceeded 20 micrograms/ml up to 340 h (14 days). Azithromycin concentrations in ELF peaked at 124 h (3.12 +/- 0.93 micrograms/ml) and were detectable up to 172 h (7 days), when they were 20 times the concurrent serum concentrations. Although the clinical significance of antibiotic concentrations in these compartments is nuclear, the sustained lung tissue penetration and extensive phagocytic accumulation demonstrated in this study support the proven efficacy of azithromycin administered on a 5-day dosage schedule in the treatment of extracellular or intracellular pulmonary infections.

    Whether COPD is generally known as a small airway disease, recent investigations suggest that vascular remodeling could play a key role in disease progression. This paper develops a specific investigation framework in order to evaluate the remodeling of the intrapulmonary vascular network and its correlation with other image or clinical parameters (emphysema score or FEV1) in patients with smoking- or genetic- (alpha-1 antitrypsin deficiency - AATD) related COPD. The developed approach evaluates the vessel caliber distribution per lung or lung region (upper, lower, 10%- and 20%- periphery) in relation with the severity of the disease and computes a remodeling marker given by the area under the caliber distribution curve for radii less than 1.6mm, AUC16. It exploits a medial axis analysis in relation with local caliber information computed in the segmented vascular network, with values normalized with respect to the lung volume (for which a robust segmentation is developed). The first results obtained on a 34-patient database (13 COPD, 13 AATD and 8 controls) showed significant vascular remodeling for COPD and AATD versus controls, with a negative correlation with the emphysema degree for COPD, but not for AATD. Significant vascular remodeling at 20% lung periphery was found both for the severe COPD and AATD patients, but not for the moderate groups. Also the vascular remodeling in AATD did not correlate with the FEV1, nor with DLCO, which might suggest independent mechanisms for bronchial and vascular remodeling in the lung.

    Intrapulmonary chemoreceptors (IPC) in the burrowing owl are reported to be much less sensitive to PCO2 than IPC in the chicken. This blunted IPC sensitivity has been suggested to be a physiological adaptation to hypercapnic subterranean environments. To investigate the natural variation IPC responses in non-burrowing species, stimulus-response characteristics of 87 IPC in 22 anesthetized Pekin ducks were recorded and compared to those from 54 previously reported chicken IPC. Average logarithmic stimulus response curves were described by slopes of - 11.2 and - 10.7 imp X (sec X InPCO2)-1 for duck and chicken, respectively. Each had slopes steeper than the - 6.87 imp X (sec X InPCO2)-1 slope reported for the burrowing owl. As with chicken IPC, slopes and intercepts of the individual curves were highly correlated in the duck. It appears that a general mechanism of receptor transduction exists in birds, with some quantitative interspecies variation. PMID:3931192

    Congenital hypothyroidism (CH) occurs in approximately 1:2,000 to 1:4,000 newborns. The clinical manifestations are often subtle or not present at birth. This likely is due to trans-placental passage of some maternal thyroid hormone, while many infants have some thyroid production of their own. Common symptoms include decreased activity and increased sleep, feeding difficulty, constipation, and prolonged jaundice. On examination, common signs include myxedematous facies, large fontanels, macroglossia, a distended abdomen with umbilical hernia, and hypotonia. CH is classified into permanent and transient forms, which in turn can be divided into primary, secondary, or peripheral etiologies. Thyroid dysgenesis accounts for 85% of permanent, primary CH, while inborn errors of thyroid hormone biosynthesis (dyshormonogeneses) account for 10-15% of cases. Secondary or central CH may occur with isolated TSH deficiency, but more commonly it is associated with congenital hypopitiutarism. Transient CH most commonly occurs in preterm infants born in areas of endemic iodine deficiency. In countries with newborn screening programs in place, infants with CH are diagnosed after detection by screening tests. The diagnosis should be confirmed by finding an elevated serum TSH and low T4 or free T4 level. Other diagnostic tests, such as thyroid radionuclide uptake and scan, thyroid sonography, or serum thyroglobulin determination may help pinpoint the underlying etiology, although treatment may be started without these tests. Levothyroxine is the treatment of choice; the recommended starting dose is 10 to 15 mcg/kg/day. The immediate goals of treatment are to rapidly raise the serum T4 above 130 nmol/L (10 ug/dL) and normalize serum TSH levels. Frequent laboratory monitoring in infancy is essential to ensure optimal neurocognitive outcome. Serum TSH and free T4 should be measured every 1-2 months in the first 6 months of life and every 3-4 months thereafter. In general, the prognosis

    Invasive pulmonary aspergillosis is a life-threatening infection in lung transplant recipients; however, no studies of the pharmacokinetics and pharmacodynamics (PKPD) of echinocandins in transplanted lungs have been reported. We conducted a single-dose prospective study of the intrapulmonary and plasma PKPD of 150 mg of micafungin administered intravenously in 20 adult lung transplant recipients. Epithelial lining fluid (ELF) and alveolar cell (AC) samples were obtained via bronchoalveolar lavage performed 3, 5, 8, 18, or 24 h after initiation of infusion. Micafungin concentrations in plasma, ELF, and ACs were determined using high-pressure liquid chromatography. Noncompartmental methods, population analysis, and multiple-dose simulations were used to calculate PKPD parameters. Cmax in plasma, ELF, and ACs was 4.93, 1.38, and 17.41 μg/ml, respectively. The elimination half-life in plasma was 12.1 h. Elevated concentrations in ELF and ACs were sustained during the 24-h sampling period, indicating prolonged compartmental half-lives. The mean micafungin concentration exceeded the MIC90 of Aspergillus fumigatus (0.0156 μg/ml) in plasma (total and free), ELF, and ACs throughout the dosing interval. The area under the time-concentration curve from 0 to 24 h (AUC0-24)/MIC90 ratios in plasma, ELF, and ACs were 5,077, 923.1, and 13,340, respectively. Multiple-dose simulations demonstrated that ELF and AC concentrations of micafungin would continue to increase during 14 days of administration. We conclude that a single 150-mg intravenous dose of micafungin resulted in plasma, ELF, and AC concentrations that exceeded the MIC90 of A. fumigatus for 24 h and that these concentrations would continue to increase during 14 days of administration, supporting its potential activity for prevention and early treatment of pulmonary aspergillosis.

    Hepatopulmonary syndrome (HPS) and portopulmonary hypertension (POPH) are pulmonary vascular complications of portal hypertension with divergent clinicopathologic features and management. The presence of intrapulmonary vascular dilatations (IPVDs), detected by agitated saline contrast-enhanced transthoracic echocardiography (cTTE), is an essential feature of HPS but is not typically characteristic of POPH. Although IPVDs have been reported rarely in POPH, the prevalence and significance of this finding have not been systematically studied. We conducted a retrospective chart review of 80 consecutive patients diagnosed with POPH from January 1, 2002 to June 30, 2014 with documentation of cTTE findings, pulmonary hemodynamics, oxygenation, and survival. A total of 34 of the 80 patients (42%) underwent cTTE during initial diagnosis of POPH. IPVDs were detected in 20/34 patients (59%); intracardiac shunting was detected in 9/34 patients (26%; 4 also had IPVDs); and 9 patients (26%) had negative cTTE with no evidence of IPVD or intracardiac shunting. Patients with IPVD had decreased survival as compared to those without IPVD (P = 0.003), a trend that persisted after exclusion of liver transplant recipients (P =  0.07). The IPVD group had a trend toward higher Model for End-Stage Liver Disease score with and without incorporating sodium (MELD or MELD-Na; P = 0.05 for both). The right ventricular index of myocardial performance (RIMP) was lower in the IPVD group (median, 0.4 versus 0.6; P = 0.006). Patients with moderate or large IPVDs (n = 6) had worse oxygenation parameters (partial pressure of arterial oxygen, diffusing capacity of the lung for carbon monoxide, and alveolar-arterial oxygen gradient) as compared to the rest of the cohort. Unexpectedly, IPVDs were frequently documented in POPH and associated with decreased survival. To further understand this observation, we recommend screening for IVPD in all patients with POPH.

    Pulmonary circulation could be one of the primary vascular targets of finest particles that can deeply penetrate into the lungs after inhalation. We investigated the effects of engineered nanoparticles on vasomotor responses of small intrapulmonary arteries using isometric tension measurements. Acute in vitro exposure to carbon nanoparticles (CNP) decreased, and in some case abolished, the vasomotor responses induced by several vasoactive agents, whereas acute exposure to titanium dioxide nanoparticles (TiO{sub 2}NP) did not. This could be attributed to a decrease in the activity of those vasoactive agents (including PGF{sub 2{alpha}}, serotonin, endothelin-1 and acetylcholine), as suggested when they were exposed to CNP before being applied to arteries. Also, CNP decreased the contraction induced by 30 mM KCl, without decreasing its activity. After endoplasmic reticulum calcium stores depletion (by caffeine and thapsigargin), CaCl{sub 2} addition induced a contraction, dependent on Store-Operated Calcium Channels that was not modified by acute CNP exposure. Further addition of 30 mM KCl elicited a contraction, originating from activation of Voltage-Operated Calcium Channels that was diminished by CNP. Contractile responses to PGF{sub 2{alpha}} or KCl, and relaxation to acetylcholine were modified neither in pulmonary arteries exposed in vitro for prolonged time to CNP or TiO{sub 2}NP, nor in those removed from rats intratracheally instilled with CNP or TiO{sub 2}NP. In conclusion, prolonged in vitro or in vivo exposure to CNP or TiO{sub 2}NP does not affect vasomotor responses of pulmonary arteries. However, acute exposure to CNP decreases contraction mediated by activation of Voltage-Operated, but not Store-Operated, Calcium Channels. Moreover, interaction of some vasoactive agents with CNP decreases their biological activity that might lead to misinterpretation of experimental data.

    2015-01-01

    Intrapulmonary arteriovenous anastomoses (IPAVA) have been known to exist in human lungs for over 60 years. The majority of the work in this area has largely focused on characterizing the conditions in which IPAVA blood flow (IPAVA) is either increased, e.g. during exercise, acute normobaric hypoxia, and the intravenous infusion of catecholamines, or absent/decreased, e.g. at rest and in all conditions with alveolar hyperoxia ( = 1.0). Additionally, IPAVA is present in utero and shortly after birth, but is reduced in older (>50 years) adults during exercise and with alveolar hypoxia, suggesting potential developmental origins and an effect of age. The physiological and pathophysiological roles of IPAVA are only beginning to be understood and therefore these data remain controversial. Although evidence is accumulating in support of important roles in both health and disease, including associations with pulmonary arterial pressure, and adverse neurological sequelae, there is much work that remains to be done to fully understand the physiological and pathophysiological roles of IPAVA. The development of novel approaches to studying these pathways that can overcome the limitations of the currently employed techniques will greatly help to better quantify IPAVA and identify the consequences of IPAVA on physiological and pathophysiological processes. Nevertheless, based on currently published data, our proposed working model is that IPAVA occurs due to passive recruitment under conditions of exercise and supine body posture, but can be further modified by active redistribution of pulmonary blood flow under hypoxic and hyperoxic conditions.

    Congenital hypothyroidism (CH) is defined as thyroid hormone deficiency present at birth. Babies with CH who are not identified and treated promptly develop severe mental retardation. Most of the babies with CH do not manifest the typical known signs and symptoms of hypothyroidism, and this is most likely due to transplacental passage of some maternal thyroid hormone in addition to some residual neonatal thyroid function, as might be seen with thyroid hypoplasia, an ectopic gland, or mild dyshormonogenesis. Screening for CH has enabled the virtual eradication of the devastating effects of mental retardation due to sporadic CH in most developed countries of the world. CH is classified into permanent and transient forms, which in turn can be divided into primary, secondary, or peripheral etiologies. Permanent CH refers to a persistent deficiency of thyroid hormone that requires life-long treatment. Transient CH refers to a temporary deficiency of thyroid hormone that is discovered at birth but recovers to normal in the first few months or years of life. In the last several decades, there have been exciting advances in our understanding of fetal and neonatal thyroid physiology. In addition, advances in molecular biology have helped in understanding the early events in thyroid gland embryogenesis, mechanisms of thyroid action in the brain, the molecular basis for many of the inborn errors of thyroid hormonogenesis, and thyroid hormone action. However, many questions and challenges are still not answered. For example, the increasing numbers of surviving small and premature neonates with abnormalities in thyroid function need definite diagnostic criteria and whether they require medical therapy. Another challenge is the dilemma of finding the best screening methodology that is sensitive and cost effective. PMID:22570946

    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

    Preoperative chest computed tomographic (CT) scans in 84 patients with biopsy-proven non-small cell bronchogenic carcinoma were reviewed. At least one adrenal gland was visualized in 70 of these. Evidence of a solid adrenal mass was present in 18 (14.5%) glands in 15 (21.4%) patients. Percutaneous needle aspiration under CT guidance confirmed metastatic malignancy in the four patients who were biopsied. Because the documented presence of adrenal metastases in non-small cell lung cancer makes surgical resection or local irradiation inappropriate, it is recommended that both adrenal glands in their entirety be specifically included whenever a staging chest CT examination is performed in patients with such tumors. Percutaneous needle biopsy for pathologic confirmation of the nature of solid adrenal masses discovered in this process is also useful.

Morphologically, the tumor showed a disorganized or "patternless" arrangement of plump to spindle cells in a collagenous stroma. Tumor cells were immunoreactive for vimentin, but not for keratin, carcinoembryonic antigen, epithelial membrane antigen, factor-VIII related antigen, S-100 protein, desmin, and actin. These immunohistochemical findings suggested fibroblastic differentiation, in keeping with the putative submesothelial origin of the tumor. The problems concerning the fine-needle aspiration (FNA) preoperative diagnosis of SFT are briefly discussed.

    Ginsenoside Rg1, extracted mainly from Panax ginseng, has been shown to exert strong pro-angiogenic activities in vivo. But it is unclear whether ginsenoside Rg1 could promote lung lymphangiogenesis to improve lymphatic transport of intrapulmonary silica in silicotic rats. Here we investigated the effect of ginsenoside Rg1 on lymphatic transport of silica during experimental silicosis, and found that ginsenoside Rg1 treatment significantly raised the silicon content in tracheobronchial lymph nodes and serum to reduce the silicon level in lung interstitium, meanwhile increased pulmonary lymphatic vessel density by enhancing the protein and mRNA expressions of vascular endothelial growth factor-C (VEGF-C) and vascular endothelial growth factor receptor-3 (VEGFR-3). The stimulative effect of ginsenoside Rg1 on lymphatic transport of silica was actively correlated with its pro-lymphangiogenic identity. And VEGFR-3 inhibitor SAR131675 blocked these above effects of ginsenoside Rg1. These findings suggest that ginsenoside Rg1 exhibits good protective effect against lung burden of silica during experimental silicosis through improving lymphatic transport of intrapulmonary silica, which is potentially associated with the activation of VEGF-C/VEGFR-3 signaling pathway.

  16. Mechanisms of 5-hydroxytryptamine-induced contraction of isolated rat intrapulmonary bronchi.

    Previous studies in our laboratory and others suggested that activation of 5-HT2 receptors mediates 5-hydroxytryptamine (5-HT)-induced contraction of airway smooth muscle and that this response is dependent in part on endogenous acetylcholine (ACh). The purpose of the present study was to confirm a role for 5-HT2 receptors and endogenous ACh in 5-HT-induced contraction of rat bronchi. In this study, we examined the effects of 5-HT2 receptor antagonists (ketanserin and LY53857), acetylcholinesterase inhibitors (physostigmine and neostigmine), and a muscarinic receptor alkylating agent [propylbenzilylcholine mustard (PBCM)] on contractile responses evoked by 5-HT and the 5-HT2 receptor agonist, alpha-methyl-5-hydroxytryptamine (alpha-Me-5-HT). Concentration-response curves generated in isolated rat intrapulmonary bronchi in response to 5-HT and alpha-Me-5-HT were superimposable. Inhibition of acetylcholinesterase by physostigmine or neostigmine potentiated contractile responses elicited by 5-HT and alpha-Me-5-HT. Alkylation of muscarinic receptors with PBCM decreased maximal responses elicited by 5-HT or alpha-Me-5-HT in a concentration-dependent manner. Maximum contraction attained with exogenous ACh was decreased by PBCM in a concentration-dependent manner and, at the highest concentration evaluated, ACh-induced contractions were abolished. 5-Hydroxytryptamine-induced contraction was inhibited competitively by low concentrations of the 5-HT2-receptor selective antagonist, ketanserin; higher concentrations abolished contractile responses to the amine. The inhibition of 5-HT-induced contractile responses by another 5-HT2-receptor selective antagonist, LY53857, was non-competitive in nature. Together, the results suggest that 5-HT contracts rat airways directly by activating 5-HT2 receptors located on airway smooth muscle and indirectly by activation of 5-HT2 receptors on parasympathetic nerve endings to cause release of ACh. The potential physiological implication of

    Purpose: To determine the stability of markers used for real-time tumor tracking after percutaneous intrapulmonary placement. Methods and Materials: A total of 42 patients with 44 lesions, 111 markers, and {>=}2 repeat computed tomography (CT) scans were studied. The tumor on the repeat CT scans was registered with the tumor on the planning CT scan. Next, the three-dimensional marker coordinates were determined on the planning CT scan and repeat CT scans. Marker stability was analyzed by the displacement of the markers and the displacement of the center of mass (COM) of the marker configurations. In addition, we assessed the reliability of using the intermarker distance as a check for displacements in the COM of the marker configurations. Results: The median marker displacement was 1.3 mm (range, 0.1-53.6). The marker displacement was >5 mm in 12% of the markers and >10 mm in 5% of the markers. The causes of marker displacement >5 mm included marker migration (2 of 13) and target volume changes (5 of 13). Nonsynchronous tumor and marker movement during breathing might have been responsible for the displacements >5 mm in the other 6 of 13 markers. The median displacement in the COM of the marker configurations was 1.0 mm (range, 0.1-23.3). Displacements in the COM of the marker configurations of {>=}2.0 mm were detected by changes in the intermarker distance of >1.5 mm in 96% of the treatment fractions. Conclusion: The median marker displacement was small (1.3 mm). Nevertheless, displacements >5 mm occurred in 12% of the markers. Therefore, we recommend the implantation of multiple markers because multiple markers will enable a quick and reliable check of marker displacement by determining the change in the intermarker distance. A displacement in the COM of the marker configuration of {>=}2.0 mm was almost always detected (96%) by a change in the distance between the markers of >1.5 mm. This enabled the displaced marker to be disabled, such that tumor localization

    The intrapulmonary pharmacokinetics of azithromycin, clarithromycin, ciprofloxacin, and cefuroxime were studied in 68 volunteers who received single, oral doses of azithromycin (0.5 g), clarithormycin (0.5 g), ciprofloxacin (0.5 g), or cefuroxime (0.5 g). In subgroups of four subjects each, the subjects underwent bronchoscopy and bronchoalveolar lavage at timed intervals following drug administration. Drug concentrations, including those of 14-hydroxyclarithromycin (14H), were determined in serum, bronchoalveolar lavage fluid, and alveolar cells (ACs) by high-pressure liquid chromatography. Concentrations in epithelial lining fluid (ELF) were calculated by the urea diffusion method. The maximum observed concentrations (mean +/- standard deviation) of azithromycin, clarithromycin, 14H, ciprofloxacin, and cefuroxime in serum were 0.13 +/- 0.07, 1.0 +/- 0.6, 0.60 +/- 0.41, 0.95 +/- 0.32, and 1.1 +/- 0.3 microgram/ml, respectively (all at 6 h). None of the antibiotics except clarithromycin (39.6 +/- 41.1 micrograms/ml) was detectable in ELF at the 6-h bronchoscopy. The movement into and persistence in cells was different for azithromycin and clarithromycin. In ACs azithromycin was not detectable at 6 h, reached its highest concentration at 120 h, and exhibited the greatest area under the curve (7,403 micrograms.hr ml-1). The peak concentration of clarithromycin (181 +/- 94.1 micrograms/ml) was greater and occurred earlier (6 h), but the area under the curve (2,006 micrograms.hr ml-1) was less than that observed for azithromycin. 14H was detectable in ACs at 6 h (40.3 +/- 5.2 micrograms/ml) and 12 h (32.8 +/- 57.2 micrograms/ml). The peak concentration of ciprofloxacin occurred at 6 h (4.3 +/- 5.2 micrograms/ml), and the area under the curve was 35.0 micrograms.hr ml-1. The data indicate that after the administration of a single dose, azithromycin, clarithromycin, and ciprofloxacin penetrated into ACs in therapeutic concentrations and that only clarithromycin was

    Congenital myopathy is a clinicopathological concept of characteristic histopathological findings on muscle biopsy in a patient with early-onset weakness. Three main categories are recognized within the classical congenital myopathies: nemaline myopathy, core myopathy, and centronuclear myopathy. Recent evidence of overlapping clinical and histological features between the classical forms and their different genetic entities suggests that there may be shared pathomechanisms between the congenital myopathies. Animal models, especially mouse and zebrafish, have been especially helpful in elucidating such pathomechanisms associated with the congenital myopathies and provide models in which future therapies can be investigated.

    1982-06-01

    While the overall prognosis for cure of bronchogenic carcinoma remains poor for most patients, there is a growing body of evidence suggesting that rationally optimized local therapy may benefit a significant subset of patients. Local therapy in this context includes any systemic therapy (such as chemotherapy or immunotherapy) that enhances local tumor control in the chest. Compared with many other human epithelial cancers, the total local tumor burden is large for many nonresectable lung cancers and not within the tolerance for control by radiation alone. Thus there is growing evidence that combined surgery and radiation treatment will improve results, especially in the differentiated tumors. Proper selection of patients is important and must include histologic stratification in addition to conventional TNM staging. It is projected that much useful research can be conducted during this decade using clinical tools now available and those that are being tested in early clinical trials throughout the world. Likely candidates for such improvements are both oxic and hypoxic radiosensitizing drugs that should decrease the death rate from uncontrolled local cancer in the chest.

    Bronchogenic cyst (BC), a rare developmental abnormality of the primitive foregut and usually found above the diaphragm, can occur in the retroperitoneum and other unusual locations where distinction from metastatic teratoma is essential. We studied 22 BCs and 34 teratomas metastatic to the retroperitoneum in men. Of 22 BCs, 17 (77%) showed well or moderate architectural differentiation toward normal tracheobronchial structures, whereas none of the teratomas did. In addition, 20 (91%) of the BCs had respiratory-type epithelium and none had enteric-type epithelium. Immature elements, atypia, and tumor necrosis were absent in BCs. All BCs expressed cytokeratin (CK) 7, and none expressed CDX-2 in immunohistochemical analysis. Teratomas had mixed enteric and respiratory-type epithelium. The majority of the glands were positive for CK7 (33 [97%]), CK20 (34 [100%]), CDX-2 (34 [100%]), and thyroid transcription factor (TTF)-1 (17 [50%]). Coexpression of CDX-2 and TTF-1 was found in 11 teratomas (32%) but none of the BCs. BCs can be reliably distinguished from teratomas based on the gross, histologic, and immunohistochemical features.

    1 Organoid cultured explants from differentiated tissues have gained renewed interest in the undertaking of physiological and pharmacological studies. In the work herein, we examined the pharmaco-mechanical properties of an in vitro model consisting of organoid cultured rings derived from rat extra- and intrapulmonary arteries, over a period of 4 days in culture. 2 Mechanical changes were quantified using isometric tension measurements on both fresh and cultured pulmonary arterial tissues, with experiments performed in the presence or absence of 10% foetal calf serum. Conventional histochemical and immunofluorescent stainings were also performed to assess tissue structure integrity and apoptosis. 3 The explants developed spontaneous rhythmic contractions (SRC) in approximately half of the vessels. SRC amplitude and time course were modified by conditions and agents acting on membrane potential (high-potassium solutions--levcromakalim, a potassium channel opener), while nitrendipine, an L-type calcium channel blocker, suppressed SRC. 4 Cultured explants also developed a hyper-reactivity to high potassium challenges (10-40 mM). Whereas contraction to serotonin (5-HT) was enhanced in intrapulmonary arteries, contraction to endothelin-1 remained unchanged after 4 days of culture. Serum did not alter contractile properties during the culture period. 5 Endothelial-dependent relaxation was maintained in response to A23187 500 microM, but was abolished in response to 10 microM carbamylcholine. 6 Histological and immuno-histological analyses revealed the absence of hypertrophied vascular wall or apoptosis. 7 In conclusion, the contractile phenotype as well as tissue structure integrity of organoid explants remain essentially intact during short-term culture, making this model suitable for pharmaco-genomic studies.

    Background Pulmonary embolism (PE) with more than 50% compromise of pulmonary circulation results significant right ventricular (RV) afterload leading to progressive RV failure, systemic hypotension and shock. Prompt restoration of thrombolysis, surgical embolectomy, or percutaneous mechanical thrombectomy (PMT) prevents progressive hemodynamic decline. We report our single center experience in high risk PE patients treated with standard pigtail catheter mechanical fragmentation followed by intrapulmonary thrombolysis as a primary therapy. Methods 50 consecutive patients with diagnosis of high risk PE defined as having shock index >1 with angiographic evidence of >50% pulmonary arterial occlusion are included in the present study. All patients underwent emergent cardiac catheterization. After ensuring flow across pulmonary artery with mechanical breakdown of embolus by rotating 5F pigtail catheter; bolus dose of urokinase (4400 IU/kg) followed by infusion for 24 h was given in the thrombus. Hemodynamic parameters were recorded and follow up pulmonary angiogram was done. Clinical and echo follow up was done for one year. Results Pigtail rotational mechanical thrombectomy restored antegrade flow in all patients. The mean pulmonary artery pressure, Miller score, Shock index decreased significantly from 41 ± 8 mmHg, 20 ± 5, 1.32 ± 0.3 to 24.52 ± 6.89, 5.35 ± 2.16, 0.79 ± 0.21 respectively (p < 0.0001). In-hospital major complications were seen in 4 patients. There was a statistically significant reduction of PA pressures from 62 ± 11 mmHg to 23±6 mmHg on follow up. Conclusions Rapid reperfusion of pulmonary arteries with mechanical fragmentation by pigtail catheter followed by intrapulmonary thrombolysis results in excellent immediate and intermediate term outcomes in patients presenting with high risk pulmonary embolism.

    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.

    PubMed Central

    Park, S; Chatterjee, V

    2005-01-01

    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

    Immunized mice after inhalation of specific antigen have the following characteristic features of human asthma: airway eosinophilia, mucus and Th2 cytokine release, and hyperresponsiveness to methacholine. A model of late-phase allergic pulmonary inflammation in ovalbumin-sensitized mice was used to address the role of the alpha4 integrin (CD49d) in mediating the airway inflammation and hyperresponsiveness. Local, intrapulmonary blockade of CD49d by intranasal administration of CD49d mAb inhibited all signs of lung inflammation, IL-4 and IL-5 release, and hyperresponsiveness to methacholine. In contrast, CD49d blockade on circulating leukocytes by intraperitoneal CD49d mAb treatment only prevented the airway eosinophilia. In this asthma model, a CD49d-positive intrapulmonary leukocyte distinct from the eosinophil is the key effector cell of allergen-induced pulmonary inflammation and hyperresponsiveness. PMID:9399955

We report a rare case with congenital lobar emphysema in a 38-days-old male infant who presented with severe respiratory distress and hypertension. Air trapping in the left upper lung and significant mediastinal shift to the right were observed on the chest x-ray. Emphysematous changes were detected on the thorax computed tomography and considered as congenital lobar emphysema. The upper left lobectomy was successfully performed by pediatric surgeons. On postoperative follow up, no sign of respiratory distress occurred and the patient was normotensive. In this report, a case with congenital lobar emphysema, which is a rare cause of respiratory distress and hypertension is discussed. PMID:27381542

    Background Mediastinal bronchogenic cyst (MBC) is the most common primary cystic lesion of the mediastinum. This study aimed to investigate the efficacy and safety of video-assisted thoracic surgery (VATS) compared with posterolateral thoracotomy (PLT) for the treatment of MBCs in a large series. Methods Patients with MBCs who underwent surgical resection between August 2005 and December 2015 were identified from the electronic database of the Department of Thoracic Surgery, West China Hospital. The patient demographic characteristics, intraoperative findings, postoperative outcomes and follow-up information were reviewed and analyzed. Results A total of 99 patients underwent cystectomy were enrolled for the present study. Of those patients, 65 underwent VATS cystectomy (VATS group) and 34 underwent PLT cystectomy (PLT group) during the same period. The VATS group had shorter operative time than the PLT group (108.77±47.81 vs. 144.62±55.16, P=0.001), less intraoperative blood loss (median 20 vs. 100 mL, P<0.001), and less pleural drainage of the first three days after surgery (median 240 vs. 400 mL, P=0.002). In addition, the length of postoperative hospital stay and duration of chest drainage for the VATS group was also shorter than those of the PLT group (4.94±2.01 vs. 8.64±5.52 days, P=0.001; 2.52±1.29 vs. 3.71±1.55 days, P<0.001, respectively). No statistical significance was revealed among the two groups with regard to the maximum diameter of the cysts, pleural atresia, incomplete resection, surgery-related complications, duration of intensive care unit stay, and postoperative complications. Conclusions Both VATS and PLT are reliable approaches for the surgical resection of MBCs. The VATS approach is superior to PLT with shorter operative time, shorter duration of chest drainage, shorter postoperative hospital stay, less intraoperative blood loss, and less pleural drainage of the first three days after surgery. We conclude that VATS should be the

    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.

    Congenital vascular anomalies are rare. The cardiovascular specialist should nevertheless be aware of the more common types of vascular anomalies and understand the implications for patient treatment and the likelihood of associated morbidity. The presentation of congenital arteriovenous malformations can range from asymptomatic or cosmetic lesions, to those causing ischemia, ulceration, hemorrhage, or high-output congestive heart failure. Treatment of large, symptomatic arteriovenous malformations often requires catheter-directed embolization prior to the attempt at complete surgical excision. Later recurrence, due to collateral recruitment, is frequent. Graded compression stockings and leg elevation are the mainstays of treatment for the predominantly venous congenital vascular anomalies. Most congenital central venous disorders are clinically silent. An exception is the retrocaval ureter. Retroaortic left renal vein, circumaortic venous ring, and absent, left-sided or duplicated inferior vena cava are relevant when aortic or inferior vena cava procedures are planned. The treatment of the venous disorders is directed at prevention or management of symptoms. Persistent sciatic artery, popliteal entrapment syndrome, and aberrant right subclavian artery origin are congenital anomalies that are typically symptomatic at presentation. Because they mimic more common diseases, diagnosis is frequently delayed. Delay can result in significant morbidity for the patient. Failure to make the diagnosis of persistent sciatic artery and popliteal entrapment can result in critical limb ischemia and subsequent amputation. Unrecognized aberrant right subclavian artery origin associated with aneurysmal degeneration can rupture and result in death. The treatment options for large-vessel arterial anomalies are surgical, sometimes in combination with endovascular techniques.

    Congenital tracheobronchial stenosis is a rare disease characterized by complete tracheal rings that can affect variable lengths of the tracheobronchial tree. It causes high levels of morbidity and mortality both due to the stenosis itself and to the high incidence of other associated congenital malformations. Successful management of this complex condition requires a highly individualized approach delivered by an experienced multidisciplinary team, which is best delivered within centralized units with the necessary diverse expertise. In such settings, surgical correction by slide tracheoplasty has become increasingly successful over the past 2 decades such that long-term survival now exceeds 88%, with normalization of quality of life scores for patients with non-syndrome-associated congenital tracheal stenosis. Careful assessment and planning of treatment strategies is of paramount importance for both successful management and the provision of patients and carers with accurate and realistic treatment counseling.

    Congenital muscular torticollis (CMT) is a rare congenital musculoskeletal disorder characterized by unilateral shortening of the sternocleidomastoid muscle (SCM). It presents in newborn infants or young children with reported incidence ranging from 0.3% to 2%. Owing to effective shortening of SCM on the involved side there is ipsilateral head tilt and contralateral rotation of the face and chin. This article reports a case of CMT in a 3½-year-old male child successfully managed by surgical release of the involved SCM followed by physiotherapy.

    Congenital adrenal hyperplasia associated with deficiency of steroid 21-hydroxylase is the most common inborn error in adrenal function and the most common cause of adrenal insufficiency in the pediatric age group. As patients now survive into adulthood, adult health-care providers must also be familiar with this condition. Over the past several years, F1000 has published numerous commentaries updating research and practical guidelines for this condition. The purposes of this review are to summarize basic information defining congenital adrenal hyperplasia and to highlight current knowledge and controversies in management. PMID:26339484

  5. Effect of surface coating on the biocompatibility and in vivo MRI detection of iron oxide nanoparticles after intrapulmonary administration.

    Superparamagnetic iron oxide nanoparticles (SPIONs) have attracted special attention as novel nanoprobes capable of improving both the therapy and diagnosis of lung diseases. For safe prospective clinical applications, their biocompatibility has to be assessed after intrapulmonary administration. This study was therefore conducted to understand the biological impact of SPIONs and their further surface-functionalization with polyethylene glycol (PEG) having either negative (i.e. carboxyl) or positive (i.e. amine) terminal in a 1-month longitudinal study following acute and sub-acute exposures. Noninvasive free-breathing MR imaging protocols were first optimized to validate SPIONs detection in the lung and investigate possible subsequent systemic translocation to abdominal organs. Pulmonary Magnetic Resonance Imaging (MRI) allowed successful in vivo detection of SPIONs in the lung using ultra-short echo time sequence. Following high-dose lung administration, MR imaging performed on abdominal organs detected transient accumulation of SPIONs in the liver. Iron quantification using Inductive coupled plasma - Mass mass spectroscopy (ICP-MS) confirmed MRI readouts. Oxidative stress induction and genotoxicity were then conducted to evaluate the biocompatibility of SPIONs with their different formulations in a mouse model. A significant increase in lipid peroxidation was observed in both acute and sub-acute sets and found to regress in a time-dependent manner. PEG functionalized SPIONs revealed a lower effect with no difference between both terminal modifications. Genotoxicity assessments revealed an increase in DNA damage and gene expression of CCL-17 and IL-10 biomarkers following SPIONs administration, which was significantly higher than surface-modified nanoparticles and decreased in a time-dependent manner. However, SPIONs with carboxyl terminal showed a slightly prominent effect compared to amine modification. PMID:26356541

    Obliterative bronchiolitis (OB) is a form of chronic rejection after lung transplantation. Lentiviral vectors (LVs) facilitate long-term gene transduction in many tissues and organs. We hypothesized that lentiviral gene transfer of interleukin (IL)-10, a potent immune-modulating cytokine, to the lung could modulate the alloimmune responses in the lung after transplantation. C57BL6 mice received LVs encoding luciferase, enhanced green fluorescent protein (eGFP), or human IL-10 (huIL-10) through airways and underwent repeated bioluminescent imaging, immunofluorescence imaging, or ELISA of lung tissues, respectively. Luciferase activities peaked at day 7 and were stable after day 28 to over 15 months. eGFP staining demonstrated LV-mediated gene transduction mainly in alveolar macrophages. LV-huIL-10 delivery resulted in stable long-term expression of huIL-10 in the lung tissue (average 3.66 pg/mg at 1 year). Intrapulmonary allograft tracheal transplantation (BALBc→C57BL6) was used as a model of OB. LV-huIL-10 or LV-eGFP were delivered 7 days before transplantation and compared with no LV-transfection group. Allograft airways at day 28 were almost completely obliterated in all the groups. However, at day 42, allograft airways treated with LV-huIL-10 showed a spectrum of attenuation in airway fibrosis ranging from complete obliteration through bubble-like partial opening to complete patency with epithelial coverage in association with a significantly reduced obliteration ratio compared with the other groups (p<0.05). In conclusion, lentivirus-mediated gene transduction is useful in achieving long-term transgene expression in the lung. Long-term IL-10 expression has the potential to attenuate allograft airway obliteration. LV-mediated gene therapy could be a useful strategy to prevent or treat OB after lung transplantation.

  7. Sildenafil, nifedipine and acetazolamide do not allow for blood flow through intrapulmonary arteriovenous anastomoses during exercise while breathing 100% oxygen.

    Blood flow through intrapulmonary arteriovenous anastomoses (IPAVAs) is known to increase in healthy humans during exercise while breathing room air, but is prevented or significantly reduced during exercise while breathing 100% O2, potentially due to vasoconstriction of IPAVAs. Thus, pharmacological interventions that target known pathways regulating the cardiopulmonary circulation may be able to prevent the hyperoxia-induced reduction in IPAVA blood flow (Q̇ IPAVA ) during exercise. In nine healthy human subjects, we investigated the effects of sildenafil (100 mg p.o.), nifedipine (20 mg p.o.) and acetazolamide (250 mg p.o. three times a day for 3 days) on Q̇ IPAVA at rest and during cycle ergometer exercise at 50, 100, 150, 200 and 250 W, while breathing room air (normoxia) and 100% O2 (hyperoxia). Transthoracic saline contrast echocardiography and a 0-5 bubble scoring system were used to detect and assess Q̇ IPAVA qualitatively; ultrasound was used to assess the blood flow velocity oftricuspid regurgitation and the left ventricular outflow tract blood flow to calculate pulmonary artery systolic pressure (PASP) and cardiac output, respectively. Without drugs, bubble scores increased significantly to ≥2 at 150 W in normoxia and to ≤2 at 200 W in hyperoxia. Only nifedipine consistently increased cardiac output at rest and during low-intensity exercise in normoxia and hyperoxia. However, there was no detectable effect of any drug on Q̇ IPAVA ; specifically, bubble scores were the same during exercise in either normoxia or hyperoxia. Accordingly, the reduction in Q̇ IPAVA during exercise while breathing 100% O2 is likely not to be due to the independent pharmacological mechanisms of action associated with sildenafil, nifedipine or acetazolamide.

  8. A methodological approach for quantifying and characterizing the stability of agitated saline contrast: implications for quantifying intrapulmonary shunt.

    Agitated saline contrast echocardiography is often used to determine blood flow through intrapulmonary arteriovenous anastomoses (Q̇IPAVA). We applied indicator dilution theory to time-acoustic intensity curves obtained from a bolus injection of hand-agitated saline contrast to acquire a quantitative index of contrast mass. Using this methodology and an in vitro model of the pulmonary circulation, the purpose of this study was to determine the effect of transit time and gas composition [air vs. sulphur hexafluoride (SF6)] on contrast conservation between two detection sites separated by a convoluted network of vessels. We hypothesized that the contrast lost between the detection sites would increase with transit times and be reduced by using contrast bubbles composed of SF6 Changing the flow and/or reducing the volume of the circulatory network manipulated transit time. Contrast conservation was measured as the ratio of outflow and inflow contrast masses. For air, 53.2 ± 3.4% (SE) of contrast was conserved at a transit time of 9.25 ± 0.02 s but dropped to 16.0 ± 1.0% at a transit time of 10.17 ± 0.06 s. Compared with air, SF6 contrast conservation was significantly greater (P < 0.05) with 114.3 ± 2.9% and 73.7 ± 3.3% of contrast conserved at a transit time of 10.39 ± 0.02 s and 13.46 ± 0.04 s, respectively. In summary, time-acoustic intensity curves can quantify agitated saline contrast, but loss of contrast due to bubble dissolution makes measuring Q̇IPAVA across varying transit time difficult. Agitated saline composed of SF6 is stabilized and may be a suitable alternative for Q̇IPAVA measurement. PMID:27365283

    Congenital cranial dysinnervation disorders (CCDD) encompass a number of related conditions and includes Duane syndrome, congenital fibrosis of the external ocular muscles, Möbius syndrome, congenital ptosis and hereditary congenital facial paresis. These are congenital disorders where the primary findings are non-progressive and are caused by developmental abnormalities of cranial nerves/nuclei with primary or secondary dysinnervation. Several CCDD genes have been found, which enhance our understanding of the mechanisms involved in brain stem development and axonal guidance. PMID:25633065

    In general, congenital diagnosis is based on: a) maternal serologic assays; b) microbiologic study of amniotic fluid or fetal blood sampling; and c) serology in children and microorganism detection by polymerase chain reaction (PCR) or culture. Congenital infections due to cytomegalovirus, herpes simplex, varicella, B19 erythrovirus and toxoplasmosis are usually the result of primary infection in the mother. Therefore, when IgG antibodies are detected before pregnancy, these infections are ruled out. Definitive serologic diagnosis of acute infection in pregnant women requires the demonstration of seroconversion (i.e., from seronegative to seropositive). In these cases, amniotic fluid or fetal blood sampling should be performed to determine the presence of intrauterine congenital infection. Cytomegalovirus, rubella and toxoplasmosis can be diagnosed by detection of specific IgM antibodies in fetal blood. However, PCR in amniotic fluid has replaced conventional prenatal diagnostic techniques, including fetal blood sampling, in the diagnosis of these infections. In the newborn, these infections may be confirmed by measuring IgM specific antibodies. B19 erythrovirus can be detected by PCR in amniotic fluid or fetal blood. Congenital varicella-zoster infection may be diagnosed on the basis of persistence of IgG antibodies after birth. Definitive diagnosis of herpes simplex virus infection requires viral isolation. Swabs or scraping from clinical specimens can be inoculated into susceptible cell lines for isolation. PMID:22305665

    The ability to reliably distinguish synchronous primary non-small-cell lung cancer (NSCLC) from intrapulmonary metastatic spread affects staging and treatment decisions in resected NSCLC. Adjuvant therapy for early-stage NSCLC is complicated and recommendations are primarily based on older data from trials that used now-outdated staging systems. Patients found to have 2 tumors with similar morphology in the same lobe are currently staged as pathologic T3 (pT3) but such cases represent a minority of patients in adjuvant lung cancer trials. Potentially more precise than tumor morphology alone, comprehensive genomic profiling technologies have the power to discriminate whether tumors in the same lobe represent 2 separate primary lesions or localized spread of a single lesion. In addition to lineage insights, tumor profiling simultaneously provides information on actionable genomic alterations. In this review we discuss the data that support the ability of molecular technologies to distinguish synchronous primary tumors from intrapulmonary metastases and discuss the use of molecular assays as an adjunct to current staging systems. Two cases are presented to highlight the potential immediate clinical implications of comprehensive genomic profiling. PMID:25911330

    Idiopathic pulmonary fibrosis is a lethal lung disease that is characterized by the accumulation of extracellular matrix and a change in lung structure. In this study, intrapulmonary pharmacokinetics of aerosolized model compounds were evaluated using rats with bleomycin-induced pulmonary fibrosis. Aerosol formulations of indocyanine green, 6-carboxyfluorescein (6-CF), and fluorescein isothiocyanate dextrans (FD; 4.4, 10, 70, and 250 kDa) were administered to rat lungs using a MicroSprayer. Indocyanine green fluorescence signals were significantly weaker in fibrotic lungs than in control lungs and 6-CF and FD concentrations in the plasma of pulmonary fibrotic animals were markedly higher than in the plasma of control animals. Moreover, disrupted epithelial tight junctions, including claudins-1, -3, and -5, were observed in pulmonary fibrotic lesions using immunofluorescence microscopy. In addition, destruction of tight junctions on model alveolar epithelial cells (NCI-H441) by transforming growth factor-β1 treatment enhanced the permeability of 6-CF and FDs through NCI-H441 cell monolayers. These results indicate that aerosolized drugs are easily distributed into the plasma after leakage through damaged tight junctions of alveolar epithelium. Therefore, the development of delivery systems for anti-fibrotic agents to improve intrapulmonary pharmacokinetics may be necessary for effective idiopathic pulmonary fibrosis therapy.

    Congenital glaucoma is a global problem and poses a diagnostic and therapeutic challenge to the ophthalmologist. A detailed evaluation under general anesthesia is advisable to establish the diagnosis and plan for management. Medical therapy has a limited role and surgery remains the primary therapeutic modality. While goniotomy or trabeculotomy ab externo is valuable in the management of congenital glaucoma, primary combined trabeculotomy–trabeculectomy offers the best hope of success in advanced cases. Trabeculectomy with antifibrotic agent and glaucoma drainage devices has a role in the management of refractory cases, and cyclodestructive procedures should be reserved for patients where these procedures have failed. Early diagnosis, prompt therapeutic intervention and proper refractive correction are keys to success. Management of residual vision and visual rehabilitation should be an integral part of the management of children with low vision and lifelong follow-up is a must. PMID:21150027

    Clubfoot is a birth defect that is marked primarily by a deformed talus (ie, ankle) and calcaneous (ie, heel) that give the foot a characteristic "club-like" appearance. In congenital idiopathic clubfoot (ie, talipes equinovarus), the infant's foot points downward (ie, equinus) and turns inward (ie, varus), while the forefoot curls toward the heel (ie, adduction). This congenital disorder has an incidence of 1 in 400 live births, with boys affected twice as often as girls. Unilateral clubfoot is somewhat more common than bilateral clubfoot and may occur as an isolated defect or in association with other disorders (eg, chromosomal aberrations, cerebral palsy, spina bifida, arthrogryposis). Infantile clubfoot deformity is painless and is correctable with early diagnosis and prompt treatment. PMID:7778903

    Congenital hemifacial hyperplasia (CHH) is a rare congenital malformation characterized by marked unilateral overdevelopment of hard and soft tissues of the face. Asymmetry in CHH is usually evident at birth and accentuated with age, especially at puberty. The affected side grows at a rate proportional to the nonaffected side so that the disproportion is maintained thr oughout the life. Multisystem involvement has resulted in etiological heterogeneity including heredity, chromosomal abnormalities, atypical forms of twinning, altered intrauterine environment, and endocrine dysfunctions; however, no single theory explains the etiology adequately. Deformities of all tissues of face, including teeth and their related tissues in the jaw, are key findings for correct diagnosis of CHH. Here an attempt has been made to present a case of CHH with its archetypal features and to supplement existing clinical knowledge. PMID:22090778

    Lipodystrophies are rare acquired and genetic disorders characterized by the selective loss of adipose tissue. One key metabolic feature of patients with congenital inherited lipodystrophy is hypertriglyceridemia. The precise mechanisms by which the lack of adipose tissue causes dyslipidemia remain largely unknown. In recent years, new insights have arisen from data obtained in vitro in adipocytes, yeast, drosophila, and very recently in several genetically modified mouse models of generalized lipodystrophy. A common metabolic pathway involving accelerated lipolysis and defective energy storage seems to contribute to the dyslipidemia associated with congenital generalized lipodystrophy syndromes, although the pathophysiological changes may vary with the nature of the mutation involved. Therapeutic management of dyslipidemia in patients with lipodystrophy is primarily based on specific approaches using recombinant leptin therapy. Preclinical studies suggest a potential efficacy of thiazolidinediones that remains to be assessed in dedicated clinical trials.

    2010-04-01

    Congenital spinal vertebral anomalies can present as scoliosis or kyphosis or both. The worldwide prevalence of the vertebral anomalies is 0.5-1 per 1000 live births. Vertebral anomalies can range from hemi vertebrae (HV) which may be single or multiple, vertebral bar with or without HV, block vertebrae, wedge shaped or butterfly vertebrae. Seventy per cent of congenital vertebral anomalies result in progressive deformities. The risk factors for progression include: type of defect, site of defect (junctional regions) and patient's age at the time of diagnosis. The key to success in managing these spinal deformities is early diagnosis and anticipation of progression. One must intervene surgically to halt the progression of deformity and prevent further complications associated with progressive deformity. Planning for surgery includes a preoperative MRI scan to rule out spinal anomalies such as diastematomyelia. The goals of surgical treatment for congenital spinal deformity are to achieve a straight growing spine, a normal standing sagittal profile, and a short fusion segment. The options of surgery include in situ fusion, convex hemi epiphysiodesis and hemi vertebra excision. These basic surgical procedures can be combined with curve correction, instrumentation and short segment fusion. Most surgeons prefer posterior (only) surgery for uncomplicated HV excision and short segment fusion. These surgical procedures can be performed through posterior, anterior or combined approaches. The advocates of combined approaches suggest greater deformity correction possibilities with reduced incidence of pseudoarthrosis and minimize crankshaft phenomenon. We recommend posterior surgery for curves involving only an element of kyphosis or modest deformity, whereas combined anterior and posterior approach is indicated for large or lordotic deformities. In the last decade, the use of growing rods and vertebral expandable prosthetic titanium rib has improved the armamentarium of the

    Congenital cataract is a leading cause of visual deprivation which can damage the developing visual system of a child; therefore early diagnosis, management and long-term follow-up are essential. It is recommended that all neonates be screened by red reflex examination at birth and suspected cases be referred to ophthalmic centers. Early surgery (<6 weeks of age, based on general neonatal health) is important for achieving the best visual outcome particularly in unilateral cases. In bilateral cases, surgery is highly recommended before appearance of strabismus or nystagmus (<10 weeks of age) with no longer than a one-week interval between the fellow eyes. Parents should be informed that surgery is a starting point and not the endpoint of treatment. Appropriate postoperative management including immediate optical correction in the form of aphakic glasses or contact lenses, or intraocular lens (IOL) implantation at the appropriate age (>1 year) is highly recommended. After surgery, amblyopia treatment and periodic follow-up examinations should be started as soon as possible to achieve a satisfactory visual outcome. Practitioners should consider the possibility of posterior capsular opacity, elevated intraocular pressure and amblyopia during follow-up, especially in eyes with microphthalmia and/or associated congenital anomalies. All strabismic children should undergo slit lamp examination prior to strabismus surgery to rule out congenital lens opacities. From a social point of view, equal and fair medical care should be provided to all children regardless of gender. PMID:27621790

    Congenital hemangiopericytoma is a rare tumor consisting of capillaries surrounded by pericytes. Only histologically can the tumor be distinguished from other vascular hamartomas. For a long time the congenital type was considered benign; however, metastases have recently been described. A histologic diagnosis of all soft-tissue sarcomas should be made. We describe two patients with congenital hemangiopericytomas in whom the diagnosis was not suspected until after histologic examination. Long-term follow-up is indicated.

    Micropenis is often an early sign of congenital hypopituitarism. It has also been associated with congenital adrenal hypoplasia in infants with anencephaly and pituitary agenesis. This report is on two infants with micropenis and congenital adrenal hypoplasia. One presented with a similar clinical course and postmortem findings to previously reported cases of adrenal hypoplasia and pituitary agenesis. The other patient represents the first reported case of an infant with micropenis and congenital adrenal hypoplasia in the absence of pituitary agenesis. The histologic patterns of adrenal hypoplasia, as well as the etiologic and clinical implications of its association with micropenis, are discussed.

    The objective of this study was to examine the relationship between responses of bovine intrapulmonary artery and vein to arachidonic acid and cyclic nucleotide levels in order to better understand the mechanism of relaxation elicited by arachidonic acid and acetylcholine. Arachidonic acid relaxed phenylephrine-precontracted arterial rings and elevated both cyclic GMP and cyclic AMP levels in arteries with intact endothelium. In contrast, endothelium-damaged arterial rings contracted to arachidonic acid without demonstrating significant changes in cyclic nucleotide levels. Indomethacin partially inhibited endothelium-dependent relaxation and abolished cyclic AMP accumulation whereas methylene blue, a guanylate cyclase inhibitor, partially inhibited relaxation and abolished cyclic GMP accumulation in response to arachidonic acid. All vessel responses were blocked by a combination of the two inhibitors. Prostaglandin (PG) I2 relaxed arterial rings and elevated cyclic AMP levels whereas PGE2 and PGF2 alpha caused contraction, suggesting that the indomethacin-sensitive component of arachidonic acid-elicited relaxation is due to PGI2 formation and cyclic AMP accumulation. The methylene blue-sensitive component is attributed to an endothelium-dependent but cyclooxygenase-independent generation of a substance causing cyclic GMP accumulation. Intrapulmonary veins contracted to arachidonic acid with no changes in cyclic nucleotide levels and PGI2 was without effect. Homogenates of intrapulmonary artery and vein formed 6-keto-PGF1 alpha, PGF2 alpha and PGE2 from (/sup 14/C)arachidonic acid, which was inhibited by indomethacin. Thus, bovine intrapulmonary vein may not possess receptors for PGI2.

    2014-01-01

    Congenital granular cell epulis is a rarely reported lesion of unknown histogenesis with a strong predilection for the maxillary alveolar ridge of newborn girls. Microscopically, it demonstrates nests of polygonal cells with granular cytoplasm, a prominent capillary network, and attenuated overlying squamous epithelium. The lesion lacks immunoreactivity for S-100, laminin, chromogranin, and most other markers except neuron-specific enolase and vimentin. Through careful observation of its unique clinical, histopathologic, and immunohistochemical features, this lesion can be distinguished from the more common adult granular cell tumor as well as other differential diagnoses.

    Congenital microvillous atrophy (CMVA) is the leading cause of neonatal secretory diarrhoea with onset either in the first 72 hours of life (early onset) or at 6–8 weeks after birth (late onset). To date over 30 cases have been reported worldwide. The prognosis for this life threatening condition continues to be poor. Therapeutic agents like somatostatin and epidermal growth factor are either ineffective or of marginal benefit. Overall five year survival after small bowel transplantation is currently ∼50%. The following brief review is aimed towards helping neonatologists/perinatologists in the early diagnosis, and management of CMVA and in counselling the parents appropriately. PMID:14970294

    An unusual case of nevus sebaceous is described. Nevus sebaceous is a congenital epidermal hamartoma of the skin and the predilection site is the head or neck. In this case the nevus followed the lines of Blaschko along the back of the left lower extremity. The linear lesion seemed papulovesicular which caused suspicion of incontinentia pigmenti or infection, and the boy received antimicrobial treatment until a biopsy revealed the correct diagnosis. We wish to emphasize this clinical picture to spare the patient and relatives from unnecessary tests, treatment and concern. PMID:21893006

    Congenital anterior urethral diverticulum (CAUD) may be found all along the anterior urethra and may present itself at any age, from infant to adult. Most children with this condition present with difficulty in initiating micturition, dribbling of urine, poor urinary stream, or urinary tract infection. A careful history will reveal that these children never had a good urinary stream since birth, and the telltale sign is a cystic swelling of the penile urethra. In this paper, we present two cases of CAUD that were managed by excision of the diverticulum with primary repair. PMID:26328174

    1976-01-01

    Congenital enzymopathic hyperlactacidemia results from a defect of utilisation of pyruvate either at the level of the pyruvate junction (pyruvate-carboxylase, pyruvate-dehydrogenase and Kreb's cycle), or at the level of the unidirectional enzymes on neo-glucogenesis and of neo-glycogenogenesis, e.g. glucose-6-phosphatase, phosphoenol-pyruvate-carboxykinase and glycogen synthetase. The enzymopathies which affect neoglucogenesis associate hyper-lactacidemia and fasting hypoglycemia and more or less marked hepatomegaly. Type I glycogenesis (von Gierke's disease) is the best known example. Enzymopathies which affect the pyruvate junction and the Krebs cycle, may be manifested in addition by: --either chronic neuropathies, e.g. Leigh's disease, recurrent ataxia, and moderate hyperalactacidemia,--or, as in congenital lactic acidoses, which have a rapid and severe prognosis with major hyperlactacidemia. Functional investigation, in particular, loading tests are of great value in orientation and justify the practice of tissue biopsy which permits the enzyme diagnosis. Recent, still unconfirmed knowledge of the pathogenesis of these diseases emphasizes the considerable importance of estimation of blood lactic acid in the investigation of metabolic acidoses of hereditary origin.

    2002-05-01

    Intrauterine infection with cytomegalovirus (CMV), a betaherpesvirus, remains the most frequent congenital virus infection in many regions of the world. Although most CMV-infected newborns lack signs of CMV infection, approximately 10% have signs that can consist of low birth weight, jaundice, hepatosplenomegaly, skin rash, microcephaly, and chorioretinitis. Neonates with signs of CMV infection at birth have high rates of audiologic and neurodevelopmental sequelae. Although postnatal therapy with ganciclovir transiently reduces virus shedding and may lessen the audiologic consequences of CMV in some infected infants, additional strategies are needed to prevent congenital CMV disease and to improve the neurodevelopmental prognosis of infants infected with CMV in utero. Some cases of intrauterine infections can be prevented in susceptible women by avoiding contact with the urine or saliva of young children who may be shedding CMV. Vaccines against CMV remain in the experimental stages of development. Termination of pregnancy can be offered to women whose infants have evidence of intrauterine CMV infection and sonographic signs of central nervous system damage. Infants who survive symptomatic intrauterine infections have high rates of neurodevelopmental sequelae and require comprehensive evaluation and therapy through center and home-based early intervention programs.

    Buffet, A; Lombes, M; Caron, P

    2015-10-01

    Congenital lipodystrophies are heterogeneous genetic diseases, leading to the loss of adipose tissue. This loss of adipose tissue can be generalized or partial, thus defining different phenotypes. These lipodystrophies have a major metabolic impact, secondary to lipotoxicity. This lipotoxicity is responsible for insulin resistance, dyslipidemia and hepatic steatosis. The severity of the metabolic impact correlates with the severity of the loss of adipose tissue. Mutations in 15 predisposition genes are currently described; BSCL2 and AGPT2 genes are the major genes in the generalized forms. On the contrary, LMNA and PPARG gene mutations are recovered in partial lipodystrophies forms. These different genes encode for proteins involved in adipocyte physiology, altering adipocyte differentiation, triglycerides synthesis and lysis or playing a major role in the lipid droplet formation. Congenital lipodystrophies treatment is based on the management of metabolic comorbidities but recombinant leptin therapy appears to have promising results. These different points have been recently discussed during the 2015 Endocrine Society Congress, notably by S. O'Rahilly and are highlighted in this review.

    2012-10-20

    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.

    This study was aimed to evaluate the efficiency of a new mesh-type nebulizer for the intrapulmonary delivery of ipratropium bromide in surgical patients under mechanical ventilation. A total of 20 patients were randomly allocated to receive 0.5 mg ipratropium bromide using either a control (Pariboy SX, Pari, Co., Starnberg, Germany, n = 10) or test (NE-SM1 NEPLUS, KTMED INC., Seoul, Korea, n = 10) nebulizer during general anaesthesia. Ipratropium bromide was nebulized continuously for 20 min. in each group. Plasma concentrations of ipratropium bromide were obtained from blood samples at preset intervals. Non-compartmental analysis of ipratropium bromide was performed to compare the efficiency of pulmonary drug delivery in both nebulizers. Population pharmacokinetic analysis of ipratropium bromide was performed. Additionally, the noise level during the nebulizer operation and the aerosol particle size for each device were measured. The dose-normalized AUC(last) was 0.10 min/L for both nebulizers. The pharmacokinetics of nebulized ipratropium bromide can be described best by a one-compartment model with first-order absorption. The apparent volume of distribution and metabolic clearance were 1340 L and 6.78 L/min, respectively. Type of nebulizer was a significant covariate for absorption rate constant. The equivalent sound level and median aerosol particle diameter were 35.0 dB and 4.52 μm for the test nebulizer, and 60.2 dB and 3.85 μm for the control nebulizer, respectively. From the standpoint of the dose-normalized AUC(last) , a new vibrating mesh-type nebulizer shows similar performance in the intrapulmonary delivery of ipratropium bromide to that of a jet-type nebulizer in surgical patients.

    Blood flow through intrapulmonary arteriovenous anastomoses (IPAVAs) has been demonstrated to increase in healthy humans during a variety of conditions; however, whether or not this blood flow represents a source of venous admixture (/) that impairs pulmonary gas exchange efficiency (i.e. increases the alveolar-to-arterial difference (A–aDO2)) remains controversial and unknown. We hypothesized that blood flow through IPAVAs does provide a source of /. To test this, blood flow through IPAVAs was increased in healthy humans at rest breathing room air and 40% O2: (1) during intravenous adrenaline (epinephrine) infusion at 320 ng kg−1 min−1 (320 ADR), and (2) with vagal blockade (2 mg atropine), before and during intravenous adrenaline infusion at 80 ng kg−1 min−1 (ATR + 80 ADR). When breathing room air the A–aDO2 increased by 6 ± 2 mmHg during 320 ADR and by 5 ± 2 mmHg during ATR + 80 ADR, and the change in calculated / was +2% in both conditions. When breathing 40% O2, which minimizes contributions from diffusion limitation and alveolar ventilation-to-perfusion inequality, the A–aDO2 increased by 12 ± 7 mmHg during 320 ADR, and by 9 ± 6 mmHg during ATR + 80 ADR, and the change in calculated / was +2% in both conditions. During 320 ADR cardiac output () and pulmonary artery systolic pressure (PASP) were significantly increased; however, during ATR + 80 ADR only was significantly increased, yet blood flow through IPAVAs as detected with saline contrast echocardiography was not different between conditions. Accordingly, we suggest that blood flow through IPAVAs provides a source of intrapulmonary shunt, and is mediated primarily by increases in rather than PASP. PMID:25085889

    Congenital self-healing reticulohistiocytosis, also known as congenital self-healing Langerhans cell histiocytosis or Hashimoto-Pritzker disease, is a Langerhans cell histiocytosis. It is characterized by skin lesions in the newborn period in an otherwise healthy infant that show a Langerhans cell infiltrate in the skin on histological analysis. These findings subsequently spontaneously involute. This report describes two newborns who presented at birth with differing presentations of congenital self-healing reticulohistiocytosis. A review of the disorder, including diagnosis and evaluation, is presented. PMID:24578781

    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.

    1981-01-01

    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

    1998-01-01

    Congenital erythropoietic porphyria (CEP) is one of the rarest autosomal-recessive disorders of the porphyrin metabolism caused by the homozygous defect of uroporphyrinogen III cosynthase. High amounts of uroporphyrin I accumulate in all cells and tissues, reflected by an increased erythrocyte porphyrin concentration and excretion of high porphyrin amounts in urine and feces. Dermal deposits of uroporphyrin frequently induce a dramatic phototoxic oxygen-dependent skin damage with extensive ulcerations and mutilations. Splenomegaly and hemolytic anemia are typical internal symptoms. Skeletal changes such as osteolysis and calcifications are frequent. Up to date 130 cases of CEP have been published. Splenectomy and erythrocyte transfusions showed some beneficial effect. Bone marrow transplantation was performed in 3 patients and stem cell transplantation in 1. The best therapy is the avoidance of sunlight. We give a report on our latest cases of CEP. PMID:10343205

    In the fetal rat, nitrofen induces congenital diaphragmatic hernia (CDH) and pulmonary vascular remodeling similar to what is observed in the human condition. Airway hyperactivity is common in infants with CDH and attributed to the ventilator-induced airway damage. The purpose of this study was to test the hypothesis that airway smooth muscle mechanical properties are altered in the nitrofen-induced CDH rat model. Lungs from nitrofen-exposed fetuses with hernias (CDH) or intact diaphragm (nitrofen) and untreated fetuses (control) were studied on gestation d 21. The left intrapulmonary artery and bronchi were removed and mounted on a wire myograph, and lung expression, content, and immunolocalization of cyclooxygenases COX-1 and COX-2 were evaluated. Pulmonary artery muscle in the CDH group had significantly (p < 0.01) lower force generation compared with control and nitrofen groups. In contrast, the same generation bronchial smooth muscle of the CDH and nitrofen groups developed higher force compared with control. Whereas no differences were found in endothelium-dependent pulmonary vascular muscle tone, the epithelium-dependent airway muscle relaxation was significantly decreased (p < 0.01) in the CDH and nitrofen groups. The lung mRNA levels of COX-1 and COX-2 were increased in the CDH and nitrofen groups. COX-1 vascular and airway immunostaining, as well as COX-1 and COX-2 lung protein content, were increased in the CDH group. This is the first report of airway smooth muscle abnormalities in the nitrofen-induced fetal rat model of CDH. We speculate that congenital airway muscle changes may be present in the human form of this disease. PMID:12612200

    Are there gender differences in prevalence, surgical results and long-term survival of patients with congenital heart disease? Available literature data allow us to state what follows. At birth there is a mild but significant prevalence of congenital heart disease in females. 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.

    Hernias in the lumbar region are abdominal wall defects that appear in two possible locations: the superior lumbar triangle of Grynfelt-Lesshaft and the inferior lumbar triangle of Petit. There are 40 cases reported in the pediatric literature, and only 16 are considered congenital, associated with the lumbocostovertebral syndrome and/or meningomyelocele. A new case is presented. A premature newborn with a mass in the left flank that increases when the patient cries and reduces easily. The complementary studies confirm the diagnosis of lumbar hernia and reveal the presence of lumbocostovertebral syndrome associated. At the time of operation a well defined fascial defect at the superior lumbar triangle of Grynfelt-Lesshaft is primarily closed. The diagnosis of lumbar hernia is not difficult to establish but it is necessary the screening of the lumbocostovertebral syndrome. We recommend the surgical treatment before 12 months of age; the objective is to close the defect primarily or to use prosthetic material if necessary. PMID:12602034

    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.

    Objective: We screened a large series of individuals with congenital mirror movements (CMM) for mutations in the 2 identified causative genes, DCC and RAD51. Methods: We studied 6 familial and 20 simplex CMM cases. Each patient had a standardized neurologic assessment. Analysis of DCC and RAD51 coding regions included Sanger sequencing and a quantitative method allowing detection of micro rearrangements. We then compared the frequency of rare variants predicted to be pathogenic by either the PolyPhen-2 or the SIFT algorithm in our population and in the 4,300 controls of European origin on the Exome Variant Server. Results: We found 3 novel truncating mutations of DCC that segregate with CMM in 4 of the 6 families. Among the 20 simplex cases, we found one exonic deletion of DCC, one DCC mutation leading to a frameshift, 5 missense variants in DCC, and 2 missense variants in RAD51. All 7 missense variants were predicted to be pathogenic by one or both algorithms. Statistical analysis showed that the frequency of variants predicted to be deleterious was significantly different between patients and controls (p < 0.001 for both RAD51 and DCC). Conclusion: Mutations and variants in DCC and RAD51 are strongly associated with CMM, but additional genes causing CMM remain to be discovered. PMID:24808016

    The foot may be the site of birth defects. These abnormalities are sometimes suspected prenatally. Final diagnosis depends on clinical examination at birth. These deformations can be simple malpositions: metatarsus adductus, talipes calcaneovalgus and pes supinatus. The prognosis is excellent spontaneously or with a simple orthopedic treatment. Surgery remains outstanding. The use of a pediatric orthopedist will be considered if malposition does not relax after several weeks. Malformations (clubfoot, vertical talus and skew foot) require specialized care early. Clubfoot is characterized by an equine and varus hindfoot, an adducted and supine forefoot, not reducible. Vertical talus combines equine hindfoot and dorsiflexion of the forefoot, which is performed in the midfoot instead of the ankle. Skew foot is suspected when a metatarsus adductus is resistant to conservative treatment. Early treatment is primarily orthopedic at birth. Surgical treatment begins to be considered after walking age. Keep in mind that an abnormality of the foot may be associated with other conditions: malposition with congenital hip, malformations with syndromes, neurological and genetic abnormalities.

    Congenital scoliosis is a lateral deformity of the spine with a disturbance of the sagittal profile caused by malformations of vertebra and ribs. Typically, early surgical intervention is the suggested treatment (before three-years-old) for young patients with congenital scoliosis. While a previous study was conducted in 2011 to investigate long-term studies supporting the necessity for this recommendation and no evidence was found, this current review, is an updated search for evidence published from 2011 through March 2015. This also failed to find any prospective or randomized controlled studies to support the hypothesis that spinal fusion surgery in patients with congenital scoliosis should be considered as evidence-based treatment. Contradictory results exist on the safety of hemivertebra resection and segmental fusion using pedicle screw fixation. When using the VEPTR (vertical expandable prosthetic titanium rib) device, studies show a high rate of complications exist. It is difficult to predict the final outcome for patients with congenital scoliosis. However, it is possible that many patients with congenital scoliosis may be able to avoid spinal surgery with the application of advanced bracing technology. Therefore, it is only prudent to advocate for conservative management first before spinal surgery is considered. PMID:26769614

    The prevalence of müllerian malformations is 1 in 200, or 0.5%. A third of the anomalies are septate, a third bicornuate uteri, 10% arcuate uterus, 10% didelphis and unicornuate uterus, and < 5% uterine and vaginal aplasia. Correct diagnosis of the malformation is most important but often very difficult. Correct treatment can only be performed if the malformation is clear. Longitudinal vaginal septums have to be removed due to potential obstetric problems. Transverse vaginal septums can cause hematocolpos and pain and have to be incised crosswise and excised so as not to shorten the vagina at the same time. Congenital vaginal agenesis occurs in Mayer-Rokitansky-Kuster-Hauser syndrome patients and in androgen insensitivity syndrome. The first choice for surgical treatment should be the new laparoscopic-assisted creation of a neovagina. Septate uterus has to be distinguished from a bicornuate uterus. Even if it is not proven to be a cause for infertility, the chance of miscarriage can be diminished by performing hysteroscopic metroplasty. Repair of a uterine septum in infertility patients often improves pregnancy rates. In contrast, surgical repair of a bicornuate uterus requires an abdominal metroplasty. This should only be performed if the patient has recurrent fetal loss due to the uterine structural defect. In a unicornuate uterus it is most important to determine if there is a second uterine horn that can cause cyclic pain if it has functioning endometrium. The only surgical option in these cases is to remove the rudimentary uterus with endometrium and hematometra, respectively.

    As a preparatory step towards the development of a complete habilitation program for children with congenital limb anomalies associated with maternal ingestion of thalidomide, the medical records of all patients with congenital limb anomalies referred to the Rehabilitation Institute of Montreal in the past decade were studied, and an examination and a thorough reassessment were made of 41 patients (21 males and 20 females). In this paper, Part I, the medical and prosthetic aspects are dealt with and a form of management is described for each type of anomaly. The conclusions are reached that prosthetic fitting and training should be initiated very early in life and that co-operation of the parent is essential to successful habilitation of a child with congenital limb anomalies.

    The objective of the present study was to ascertain whether cyanide shares the properties of methylene blue as a selective inhibitor of vascular smooth muscle relaxation elicited by agents that stimulate the formation of cyclic GMP. Experiments were performed with endothelium-intact rings prepared from bovine intrapulmonary artery. Methylene blue, a good inhibitor of soluble guanylate cyclase, antagonized both arterial relaxation and cyclic GMP accumulation in response to sodium nitroprusside, glyceryl trinitrate, S-nitroso-N-acetylpenicillamine and acetylcholine. In contrast, cyanide inhibited only the responses to sodium nitroprusside. Increasing concentrations of methylene blue depressed resting arterial levels of cyclic GMP and caused slowly developing but marked contractions whereas cyanide was without effect. Contractile responses to phenylephrine, potassium and U46619 were potentiated by methylene blue but not by cyanide. Preincubation of dilute solutions of cyanide containing sodium nitroprusside in oxygenated Krebs' buffer at 37 degrees C for 15 min before addition to bath chambers depressed relaxation and cyclic GMP accumulation caused by sodium nitroprusside markedly. Similar treatment of glyceryl trinitrate, however, failed to alter its effects in arterial rings. A chemical inactivation of sodium nitroprusside by cyanide appears to account for the specific inhibitory action of cyanide on arterial responses to sodium nitroprusside. This study indicates clearly that cyanide does not share the properties of methylene blue as an inhibitor of arterial relaxation elicited by vasodilators that stimulate cyclic GMP formation.

    Colistin is an old antibiotic that has recently gained a considerable renewal of interest for the treatment of pulmonary infections due to multidrug-resistant Gram-negative bacteria. Nebulization seems to be a promising form of administration, but colistin is administered as an inactive prodrug, colistin methanesulfonate (CMS); however, differences between the intrapulmonary concentrations of the active moiety as a function of the route of administration in critically ill patients have not been precisely documented. In this study, CMS and colistin concentrations were measured on two separate occasions within the plasma and epithelial lining fluid (ELF) of critically ill patients (n = 12) who had received 2 million international units (MIU) of CMS by aerosol delivery and then intravenous administration. The pharmacokinetic analysis was conducted using a population approach and completed by pharmacokinetic-pharmacodynamic (PK-PD) modeling and simulations. The ELF colistin concentrations varied considerably (9.53 to 1,137 mg/liter), but they were much higher than those in plasma (0.15 to 0.73 mg/liter) after aerosol delivery but not after intravenous administration of CMS. Following CMS aerosol delivery, typically, 9% of the CMS dose reached the ELF, and only 1.4% was presystemically converted into colistin. PK-PD analysis concluded that there was much higher antimicrobial efficacy after CMS aerosol delivery than after intravenous administration. These new data seem to support the use of aerosol delivery of CMS for the treatment of pulmonary infections in critical care patients. PMID:25267660

    Sialolipoma is a newly recognized tumor of the major and minor salivary glands and represents only 0.3% of all salivary gland tumors. Only 3 cases of congenital sialolipoma are available in the literature. In the current case, we performed a total parotidectomy with facial nerve preservation on a 12-week-old infant exhibiting huge mass in the parotid region. Histopathology results showed sialolipoma. There was no recurrence at the 18-month follow-up. Although it is a very rare disease in infants, congenital sialolipoma should be kept in mind in patients with parotid mass. The primary treatment is parotidectomy with facial nerve preservation. PMID:26594977

    OBJECTIVE: To review the cases of patients with congenital lobar emphysema (CLE) submitted to surgical treatment at two university hospitals over a 30-year period. METHODS: We reviewed the medical records of children with CLE undergoing surgical treatment between 1979 and 2009 at the Botucatu School of Medicine Hospital das Clínicas or the Mogi das Cruzes University Hospital. We analyzed data regarding symptoms, physical examination, radiographic findings, diagnosis, surgical treatment, and postoperative follow-up. RESULTS: During the period studied, 20 children with CLE underwent surgery. The mean age at the time of surgery was 6.9 months (range, 9 days to 4 years). All of the cases presented with symptoms at birth or during the first months of life. In all cases, chest X-rays were useful in defining the diagnosis. In cases of moderate respiratory distress, chest CT facilitated the diagnosis. One patient with severe respiratory distress was misdiagnosed with hypertensive pneumothorax and underwent chest tube drainage. Only patients with moderate respiratory distress were submitted to bronchoscopy, which revealed no tracheobronchial abnormalities. The surgical approach was lateral muscle-sparing thoracotomy. The left upper and middle lobes were the most often affected, followed by the right upper lobe. Lobectomy was performed in 18 cases, whereas bilobectomy was performed in 2 (together with bronchogenic cyst resection in 1 of those). No postoperative complications were observed. Postoperative follow-up time was at least 24 months (mean, 60 months), and no late complications were observed. CONCLUSIONS: Although CLE is an uncommon, still neglected disease of uncertain etiology, the radiological diagnosis is easily made and surgical treatment is effective. PMID:24068262

    Congenital infection with Trypanosoma cruzi is a global problem, occurring on average in 5% of children born from chronically infected mothers in endemic areas, with variations depending on the region. This presentation aims to focus on and update epidemiological data, research methods, involved factors, control strategy and possible prevention of congenital infection with T. cruzi. Considering that etiological treatment of the child is always effective if performed before one year of age, the diagnosis of infection in pregnant women and their newborns has to become the standard of care and integrated into the surveillance programs of syphilis and human immunodeficiency virus. In addition to the standard tests, polymerase chain reaction performed on blood of neonates of infected mothers one month after birth might improve the diagnosis of congenital infection. Recent data bring out that its transmission can be prevented through treatment of infected women before they become pregnant. The role of parasite genotypes and host genetic factors in parasite transmission and development of infection in foetuses/neonates has to be more investigated in order to better estimate the risk factors and impact on health of congenital infection with T. cruzi.

    The Alberta Congenital Anomalies Surveillance System was started in 1966 in response to the thalidomide tragedy earlier in the decade. It was one of four provincial surveillance systems on which the federal government relied for baseline statistics of congenital anomalies. The government now collects data from six provinces and one territory. The Alberta Congenital Anomaly Surveillance System originally depended on three types of notification to the Division of Vital Statistics, Department of Health, Government of Alberta: birth notice and certificates of death and stillbirth; increased sources of ascertainment have greatly improved data quality. We present the data for 1980-86 and compare the prevalence rates of selected anomalies with the rates from three other surveillance systems. Surveillance systems do not guarantee that a new teratogen will be detected, but they are extremely valuable for testing hypotheses regarding causation. At the very least they provide baseline data with which to compare any deviation or trend. For many, if not most, congenital anomalies total prevention is not possible; however, surveillance systems can be used to measure progress in prevention. PMID:2819634

    Various dermatoglyphic parameters like finger print pattern, atd angle, absolute ridge count & ab, bc ,cd, and ad ridge counts were observed in 150 cases of congenital cardiac disease, comprising of 72 cases of Ventricular Septal Defects (VSD), 60 cases of Atrial Septal Defects (ASD), 9 cases of Coarctation of Aorta (COA) & 9 cases of Tetralogy of Fallot's (TOF). Same dermatoglyphic parameters were also studied in 300 controls and statistical comparison of cases and controls was done. In our study it was observed that the congenital cardiac disease cases exhibited preponderance of whorls (55.8%) with decrease in loop pattern (36.2%) as compared to those of controls and the difference was highly significant (P<0.001). The difference in the mean total finger ridge count (TFRC) of the controls and of the cases of Congenital Cardiac Diseases (CCD) was found to be highly significant (P<0.001), while the  mean atd angle in the cases of Congenital Cardiac Disease (CCD) was widen up and was statistically significant too. The mean ab, the mean bc ridge, the mean cd ridge and the mean ad ridge counts were also higher in the various type of CCD as compared to that controls and on statistical comparison, the difference was found to be highly significant.

    Uncommon congenital hemangiomas differ from common infantile hemangiomas in their appearance, postnatal behavior, histopathology, and immunohistologic staining. Two types are well described in the literature: noninvoluting congenital hemangioma (NICH) and rapidly involuting congenital hemangioma (RICH). We report a series of infants with another presentation of congenital hemangioma that arises prenatally and is nearly regressed at birth. This was a retrospective case series. We describe six infants with unusual congenital vascular tumors. Each lesion presented at birth as a violaceous, atrophic plaque with a surrounding pale halo. The lesions involuted in infancy, fading in color and becoming atrophic, with prominent central veins, similar to RICH in the final stage of regression. The distinctive morphology and behavior suggests that these tumors undergo a life cycle of proliferation and involution during fetal life. We describe a new variant of congenital hemangioma that we refer to as rapidly involuting congenital hemangioma with fetal involution.

    Background A comprehensive survey of the prevalence of congenital anomalies in baboons has not been previously reported. We report the congenital anomalies observed over a 26-year period in a large captive baboon colony. Methods A computer search was performed for all baboon congenital anomalies identified at necropsy and recorded on necropsy submissions. Results We identified 198 congenital anomalies in 166 baboons from 9,972 necropsies (1.66% of total necropsies). The nervous, urogenital, musculoskeletal, and cardiovascular systems were most commonly affected. The most common organs affected were the brain, bone, heart, testicle, kidney, penis, aorta, and skeletal muscle. The most frequent congenital anomalies were blindness, seizures, and hydrocephalus. Conclusions The baboon has an overall frequency of congenital anomalies similar to humans and other nonhuman primates. Although the most frequently affected systems are similar, congenital anomalies involving the digestive system appear to be less common in the baboon. PMID:21332757

    Purpose Although functional outcomes following reconstruction for congenital hand differences are frequently described, much less is known regarding children’s ability to cope with psychosocial effects of these conditions. We qualitatively explored stress and coping mechanisms among children following reconstructive surgery for congenital hand differences. Methods Forty patients and their parents participated in semi-structured interviews examining stress related to hand functioning and appearance, emotional responses to stress, and coping strategies. Interviews were audio-taped, transcribed, and analyzed thematically. A consensus taxonomy for classifying content evolved from comparisons of coding by two reviewers. Themes expressed by participants were studied for patterns of connection and grouped into broader categories. Results In this sample, 58% of children and 40% of parents reported stress related to congenital hand differences, attributed to functional deficits (61%), hand appearance (27%), social interactions (58%), and emotional reactions (46%). Among the 18 children who reported stress, 43% of parents were not aware of the presence of stress. Eight coping strategies emerged, including humor (12%), self-acceptance (21%), avoidance (27%), seeking external support (30%), concealment (30%), educating others (9%), support programs (21%) and religion (24%). Conclusions Although children with congenital hand differences often experience emotional stress related to functional limitations and aesthetic deformities, many apply positive coping mechanisms that enhance self-esteem and self-esteem. Clinicians caring for children with congenital hand differences should inform families about potential sources of stress in order to direct resources toward strengthening coping strategies and support systems.

    1. The effects of endotoxin (E. coli lipopolysaccharide, LPS) and heat inactivated group B Streptococcus (GBS) were studied on the contractile responses to noradrenaline (NA) in isolated pulmonary arteries and on the activity of the constitutive and inducible nitric oxide synthase (NOS) in lung fragments of neonatal piglets. 2. Short-term (< or = 5 h) incubation with LPS (1 micrograms ml-1) or GBS (3 x 10(7) colonies forming units ml-1) did not modify the vascular responsiveness to NA (10(-8) M-10(-4) M) in isolated intrapulmonary arteries. However, long-term incubation (20 h) with LPS or GBS produced a significant reduction in the maximal contractile responses and shifted the concentration-response curve for NA downwards. 3. Endothelium removal or the cyclo-oxygenase inhibitor meclofenamate (10(-5) M) did not affect the GBS- and LPS-induced hyporesponsiveness to NA. 4. The presence of the nitric oxide (NO) precursor, L-arginine (10(-5) M), 30 min prior to the contractility challenge increased the LPS- and GBS-induced pulmonary vascular hyporesponsiveness to NA. In contrast, the addition, prior to the challenge with NA, of the NOS inhibitor NG-nitro-L-arginine methyl ester (L-NAME, 10(-4) M) or coincubation with dexamethasone (3 x 10(-6) M), a potent inhibitor of the induction of NOS, or with the protein synthesis inhibitor cycloheximide (10(-5) M) completely restored the reactivity to NA in LPS- and GBS-treated pulmonary arteries.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:7545518

    Esophageal duplication cyst is a rare congenital embryonal gastrointestinal (GI) malformation which is diagnosed most commonly in childhood. In adults, they can present with a variety of symptoms ranging from dysphagia, chest pain, epigastric discomfort, and vomiting to more serious complications including infections, hemorrhage, and ulcerations. A 30-year-old male presented with gradually progressive dysphagia to solids for 4 months without significant weight loss. Clinical examination and routine laboratory examination were unrevealing. Upper GI endoscopy revealed a well-defined submucosal lesion bulging into the esophageal lumen involving the right antero-lateral wall of the distal esophagus. The overlying mucosa was normal with mild luminal narrowing but gastroscope could be negotiated across this narrowing. Differential diagnosis included lipoma, leiomyoma or GI stromal tumors. Contrast-enhanced computed tomography of thorax revealed a 3.5 × 2.3 × 3 cm well-defined homogenous hypodense lesion involving the right antero-lateral wall of the distal thoracic esophagus with likely possibility of submucosal or intramural lesion. Subsequently, endoscopic ultrasonography (EUS) revealed a 3.3 × 2.8 cm homogenous hypoechoic lesion without any vascularity involving the distal esophagus wall suggestive of duplication cyst. The lesion was intramural in location as muscularis propria was seen to go around the lesion. Bronchogenic cyst was excluded due to absence of cartilage and close proximity of the cyst to lumen. Fine-needle aspiration was not attempted in view of high risk of introducing infection. Being symptomatic, the patient underwent complete surgical excision of the cyst with exteriorization of the base which on histopathology confirmed duplication cyst. Esophageal duplication cysts are exceedingly rare congenital embryonal malformations with estimated prevalence of 0.0122% arising from aberration of posterior division of embryonic foregut at 3 - 4 weeks of

    This is the first report of a group of patients with congenital esotropia examined for motor and sensory evidence of binocularity a minimum of 3 years after alignment by botulinum. Evidence for binocularity was clearly present in approximately one half of the patients. Lag time to satisfactory alignment was at least 1 month (average, 5 months) following the initial botulinum injection. The results must be considered preliminary. However, when these results are compared with those of patients with congenital esotropia aligned by incisional surgery by age 2 years and examined with the same testing devices by this same investigator, botulinum alignment appears to be less effective than surgical alignment in establishing evidence for binocularity (P < 0.005).

    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.

    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.

  6. Classifying sex biased congenital anomalies

    SciTech Connect

    Lubinsky, M.S.

    1997-03-31

    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.

  7. Congenital errors of folate metabolism.

    1995-09-01

    Congenital errors of folate metabolism can be related either to defective transport of folate through various cells or to defective intracellular utilization of folate due to some enzyme deficiencies. Defective transport of folate across the intestine and the blood-brain barrier was reported in the condition 'Congenital Malabsorption of Folate'. This disease is characterized by a severe megaloblastic anaemia of early appearance associated with mental retardation. Anaemia is folate-responsive, but neurological symptoms are only poorly improved because of the inability to maintain adequate levels of folate in the CSF. A familial defect of cellular uptake was described in a family with a high frequency of aplastic anaemia or leukaemia. An isolated defect in folate transport into CSF was identified in a patient suffering from a cerebellar syndrome and pyramidal tract dysfunction. Among enzyme deficiencies, some are well documented, others still putative. Methylenetetrahydrofolate reductase deficiency is the most common. The main clinical findings are neurological signs (mental retardation, seizures, rarely schizophrenic syndromes) or vascular disease, without any haematological abnormality. Low levels of folate in serum, red blood cells and CSF associated with homocystinuria are constant. Methionine synthase deficiency is characterized by a megaloblastic anaemia occurring early in life that is more or less folate-responsive and associated with mental retardation. Glutamate formiminotransferase-cyclodeaminase deficiency is responsible for massive excretion of formiminoglutamic acid but megaloblastic anaemia is not constant. The clinical findings are a more or less severe mental or physical retardation. Dihydrofolate reductase deficiency was reported in three children presenting with a megaloblastic anaemia a few days or weeks after birth, which responded to folinic acid.

    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.

    Introduction. Congenital portosystemic venous malformations are rare abnormalities in which the portal blood drains into a systemic vein and which are characterized by extreme clinical variability. Case Presentations. The authors present two case reports of a congenital extrahepatic portosystemic shunt (Type II). In the first patient, apparently nonspecific symptoms, such as headache and fatigue, proved to be secondary to hypoglycemic episodes related to the presence of a portosystemic shunt, later confirmed on imaging. During portal vein angiography, endovascular embolization of the portocaval fistula achieved occlusion of the anomalous venous tract. In the second patient, affected by Down's syndrome, the diagnosis of a portosystemic malformation was made by routine ultrasonography, performed to rule out concurrent congenital anomalies. Because of the absence of symptoms, we chose to observe this patient. Conclusions. These two case reports demonstrate the clinical heterogeneity of this malformation and the need for a multidisciplinary approach. As part of a proper workup, clinical evaluation must always be followed by radiographic diagnosis. PMID:25709849

    Congenital generalized terminal hypertrichosis is a rare disease, especially when associated with gingival hyperplasia. Congenital hypertrichosis can be a clinical feature of several syndromes, so these patients must be studied by a multidisciplinary team that should include a dermatologist, geneticist, psychologist, odontologist, and an endocrinologist. We report a 7-year-old girl with congenital generalized hypertrichosis and gingival hyperplasia, and analyze the clinical approach, differential diagnosis, and treatment. PMID:11994171

    The Congenital Heart Surgeons' Society is a group of over 100 pediatric heart surgeons representing 72 institutions that specialize in the treatment of patients with congenital heart defects. The Society began in 1972 and incorporated as a not-for-profit charitable organization in 2004. It has become the face and voice of congenital heart surgery in North America. In 1985, the Society established a data center for multicenter clinical research studies to encourage congenital heart professionals to participate in improving outcomes for our patients. The goals of the Congenital Heart Surgeons' Society are to stimulate the study of congenital cardiac physiology, pathology, and management options which are instantiated in data collection, multi-institutional studies, and scientific meetings. Honest and open discussion of problems with possible solutions to the challenges facing congenital heart professionals have been the strength of the Congenital Heart Surgeons' Society. It is imperative for the growth of an organization to know from where it came in order to know to where it is going. The purpose of this article is to review the history of the Congenital Heart Surgeons' Society.

    Cases with congenital heart defects (CHD) often have other associated anomalies. The purpose of this investigation was to assess the prevalence and the types of associated anomalies in CHD in a defined population. The anomalies associated with CHD were collected in all live births, stillbirths and terminations of pregnancy during 26 years in 346,831 consecutive pregnancies of known outcome in the area covered by our population based registry of congenital anomalies. Of the 4005 cases with CHD born during this period (total prevalence of 115.5 per 10,000), 1055 (26.3%) had associated major anomalies. There were 354 (8.8%) cases with chromosomal abnormalities including 218 trisomies 21, and 99 (2.5%) nonchromosomal recognized dysmorphic conditions. There were no predominant recognized dysmorphic conditions, but VACTERL association. However, other recognized dysmorphic conditions were registered including Noonan syndrome, fetal alcohol syndrome, and skeletal dysplasias. Six hundred and two (15.0%) of the cases had non syndromic, non chromosomal multiple congenital anomalies (MCA). Anomalies in the urinary tract, the musculoskeletal, the digestive, and the central nervous systems were the most common other anomalies. Prenatal diagnosis was obtained in 18.7% of the pregnancies. In conclusion the overall prevalence of associated anomalies, which was one in four infants, emphasizes the need for a thorough investigation of cases with CHD. A routine screening for other anomalies may be considered in infants and in fetuses with CHD. One should be aware that the anomalies associated with CHD can be classified into a recognizable anomaly, syndrome or pattern in one out of nine cases with CHD. PMID:25497206

    The following review seeks to summarise the current data regarding reproductive outcomes associated with congenital uterine anomalies. Such malformations originate from adverse embryologic events ranging from agenesis to lateral and vertical fusion defects. Associated renal anomalies are common both for the symmetric and asymmetric malformations. While fertility is minimally impacted upon by müllerian anomalies in most cases, such malformations have historically been associated with poor obstetric outcomes such as recurrent miscarriage, second trimester loss, preterm delivery, malpresentation and intrauterine foetal demise (IUFD). The following review delineates the existing literature regarding such outcomes and indicates therapies, where applicable, to optimise the care of such patients.

    Asbestos-associated malignancies are one of the major industrial hazards of recent decades and will continue to be so until beyond the end of the century. It has been estimated that, in the United States alone, there will be 131,200 cancer deaths as a result of asbestos exposure. At present the early lesions are detected radiologically, by which time intervention is no longer effective. The aim of this study was to test the value of a battery of serum biomarkers in the early detection of malignancy and in distinguishing between the early stages of mesothelioma and bronchogenic carcinoma. Many of the biomarkers had no discriminating value but on the basis of four such markers (namely TPA, CEA, HA and ferritin) it has been possible to distinguish between the late stages of the two malignancies and asbestosis. The results are discussed in terms of their possible application to the detection of early pre-malignant lesions in a screened population of asbestos-exposed persons, with the aim of attempting to prevent cancer death in such early detected cases.

    Arrhythmias figure prominently among the complications encountered in the varied and diverse population of patients with congenital heart disease, and are the leading cause of morbidity and mortality. The incidence generally increases as the patient ages, with multifactorial predisposing features that may include congenitally malformed or displaced conduction systems, altered hemodynamics, mechanical or hypoxic stress, and residual or postoperative sequelae. The safe and effective management of arrhythmias in congenital heart disease requires a thorough appreciation for conduction system variants, arrhythmia mechanisms, underlying anatomy, and associated physiology. We, therefore, begin this review by presenting the scope of the problem, outlining therapeutic options, and summarizing congenital heart disease-related conduction system anomalies associated with disorders of the sinus node and AV conduction system. Arrhythmias encountered in common forms of congenital heart disease are subsequently discussed. In so doing, we touch upon issues related to risk stratification for sudden death, implantable cardiac devices, catheter ablation, and adjuvant surgical therapy. PMID:19898654

    Congenital cytomegalovirus infection affects 0.7% of live births and is the leading cause of congenital neurological handicaps of infectious origin. However, systematic screening of this infection has not been implemented in pregnancy or at birth in any country. This apparent paradox has been justified by the unavailability of an efficient vaccine and by the scarcity of data available on the treatment of congenital CMV. However, in the last decade interesting new data on the management of this congenital infection has emerged including new results on both neonatal and postnatal treatments. This review provides an update on the potential benefits of antiviral treatment and on passive immunisation both in the neonatal and the antenatal periods. These suggest a benefit to a proactive approach for neonatal and prenatal congenital infections. PMID:27043943

    In the course of the study "Toxoplasmosis and Prematurity" 330 blood samples from twins were examined. Our findings in a series of 21 premature twins (maternal sera were also examined) are reported in this paper. Toxoplasma antibodies were detected by the Sabin-Feldman test and specific IgM antibodies by the Remington test. The classical form of congenital toxoplasmosis was present in five pairs of twins, while toxoplasmosis was subclinical at birth in both twins of three pairs. The pattern of disease varied very much in seven pairs of twins. In one twin of two pairs signs of disease were present, while his cotwin appeared unaffected but with strongly positive result of SFT. The most interesting observation, however, is that in three pairs, one twin was infected and had evident congenital toxoplasmosis, while his cotwin was not, as proven by the disappearance of the Toxoplasma antibodies. This finding undoubtedly indicates the importance of whether the placenta is intact or not for the transmission of the infection.

    Between February 1988 and June 1995, 24 congenital dislocations of the knee joints (17 patients) were reduced with closed methods including immediate reduction, serial casting, or traction in patients from 10 min to 26 days old. At an average follow-up of 4 years and 10 months, an excellent or good result was achieved if there were no associated anomalies. Fair or poor results were the result of delayed treatment or associated musculoskeletal anomalies including arthrogryposis multiplex congenita or Larsen's syndrome. Routine check of the hip dislocation is suggested. Diagnosis with manual testing was difficult, and other methods such as radiography or sonography were suggested in combination to detect hip dysplasia. The dislocated knee should be reduced before treating the hip dislocation. Concomitant treatment of the congenital dislocation of the knee and the hip with Pavlik harness provided satisfactory results. When late, progressive, genu valgus deformity occurred because of global instability of the knee and asymmetric physeal growth, reconstruction of the medial structures of the knee and prolonged bracing provided good results.

    Congenital dislocation or subluxation of the hip (congenital acetabular dysplasia) is a complete or partial displacement of the femoral head out of the acetabulum. The physical signs essential for diagnosis are age related. In newborns the tests for instability are the most sensitive. After the neonatal period, and until the age of walking, tightness of the adductor muscles is the most reliable sign. Early diagnosis is vital for successful treatment of this partially genetically determined condition. Various therapeutic measures, ranging from abduction splinting to open reduction and osteotomy, may be required. Following diagnosis in the first month of life, the average treatment time in one recent series was only 2.3 months from initiation of therapy to attainment of a normal hip. When the diagnosis was not made until 3 to 6 months of age, ten months of treatment was required to achieve the same outcome. When the diagnosis is not made, or the treatment is not begun until after the age of 6, a normal hip will probably not develop in any patient.

    A review of the literature reveals a need to clarify the pathologic physiology of congenital polychlorinated biphenyl (PCB) poisoning, which is characterized by intrauterine growth retardation, brown staining of the skin and mucous membranes as in Addison's disease, natal teeth, widely open fontanelles and sagittal suture and apparent overgrowth of the gingiva. The skull abnormalities may represent irregular calcification, with natal teeth appearing because the bone of the mandible is penetrated more easily than usual. Some fetuses were poisoned at the time the mothers ingested the oil; others were affected in the subsequent years from residual contamination in the mothers' bodies. The misadventure in Japan was repeated in Taiwan in 1979. The seven congenital cases in Taiwan reported thus far seem to differ from those in Japan. In Taiwan the noses were somewhat black, two of the infants did not have low birth weight and the osseous abnormalities of the skull and gingival hyperplasia were not observed. Systematic followup studies should be made in Taiwan of the children born within 2 years of maternal poisoning with PCBs. Special attention should be given to age at first dentition and skull-X-rays for spotty calcification, among other measures of physical, neurologic and intellectual development.

    A 7-month-old male child is reported with congenital cholesteatoma of the external auditory canal. We describe the clinical features, computed tomography finding and surgical treatment. Congenital cholesteatomas can occur within the temporal bone. There are six places of location: (1) petrous apex, (2) mastoid, (3) middle ear, (4) both middle ear and mastoid, (5) external ear canal and (6) within the squamous portion of the temporal bone. Congenital cholesteatoma of the external auditory canal is rare. Generally, it appears in the canal floor without lesions in the tympanic membrane. Computed tomography completes the study. Treatment consists of excision of the mass.

    Congenital hypothyroidism is one of the most urgent diseases of the neonate. When diagnosed and treated at an early stage, its most important complication, mental retardation, is preventable. The signs of congenital hypothyroidism are nonspecific in neonates. Only 5% of the cases have characteristic clinical findings. One of the most important and earliest signs is prolonged jaundice during the neonatal period. We report herein a case of congenital hypothyroidism, who presented with icterus accompanied with sludge formation into the gallbladder, which disappeared after treatment with L-thyroxine.

    Congenital epulis, a benign tumor of the oral cavity, is an extremely rare condition in newborn. It may lead to mechanical obstruction, therefore resulting in respiratory distress and difficulty in feeding. Addressing the problem may need a multidisciplinary team approach at the time of birth. Antenatal ultrasonography and perinatal magnetic resonance imaging are an adjunct to treatment planning. Prenatal diagnosis remains difficult as the findings are nonspecific due to the late development of the tumor. Surgical excision is, therefore, the treatment of choice. Our report discusses this condition and the treatment thereafter on a newborn, with an epulis originating from the upper alveolar ridge discovered at birth. Histological examination confirmed the diagnosis of large polygonal granular cells. The mass was excised under general anesthesia, and the outcome was good after surgery allowing regular feeds on the second postoperative day. PMID:26980979

    Critical congenital heart disease (CCHD) is a heart lesion for which neonates require early surgical intervention to survive. Without intervention, the rates of mortality and survival with significant disability are extremely high. Early diagnosis can potentially improve health outcomes in newborns with CCHD. Until recent years, no routine screening protocol existed. In the last few years, pulse oximetry screening for CCHD in newborns has been added to the list of recommended uniform screening panels and advocated by several health-care authorities. A positive screening test result warrants an echocardiogram to evaluate for CCHD. Newborn screens do not usually require parental consent. However, most of the states mandates in the United States include a statement allowing exemption from the screen on the basis of parental religious or personal beliefs. PMID:27390667

The first case is a patient with double gallbladder and concomitant choledocholithiasis. The probable diagnosis of double gallbladder was made preoperatively by computed tomography. The patient underwent a successful open cholecystectomy and common bile duct exploration. In the second case, two cystic formations in the place of gallbladder are demonstrated with ultrasound scan in a woman with acute cholecystitis. At surgery, two gallbladders were found. A brief review of epidemiology and anatomy of double gallbladder is included, along with a discussion of the difficulties in diagnosis and treatment of this condition.

    The natural history and electrophysiological findings of 52 patients with X-linked congenital retinoschisis with a follow-up of up to 26 years are described. The mean visual acuity was reduced to 0.24 +/- 0.2 and remained unchanged in most patients during this time. If visual loss occurred, it usually happened in the first decennium. The complications were retinal detachments in 11% and vitreous hemorrhages in 4% of the eyes. In general, the vitreous hemorrhages resolved spontaneously. Retinal detachments were treated successfully with conventional buckling procedures. Redetachments occurred in about 40%. Prophylactic laser coagulation was of no use because it was complicated by detachment in 43% of our series. The electro-oculogram was usually normal. In addition to the known electrorentinographic findings of normal a-wave and reduced b-wave amplitudes, we found prolonged b-wave latencies and implicit times, as well as a reduced 30 Hz flicker response.

    Congenital abdominal wall defects that are located outside of the anterior wall are extremely rare and difficult to classify because there are no well accepted guidelines. There are two regions outside of the anterior wall: the flank or lateral wall; and the lumbar region. We report the case of a patient with an oval 3 cm-diameter hernia defect located above the anterior axillary line, which affects all layers of the muscular wall. An anorectal malformation consisting of a recto-vestibular fistula was also identified, and chest X-ray showed dextrocardia. The suggested treatment is repair of the defect before 1 year of age. Given that the anomalies described may accompany lateral abdominal wall hernia, it is important to diagnose and treat the associated defects.

    HLA-A, HLA-B, HLA-C, and HLA-D typing was performed in 47 mothers of patients suffering from ocular toxoplasmosis to investigate whether an immunogenetic predisposition exists for developing congenital toxoplasmosis in their offspring. No significant association between any HLA antigen was observed in the mothers of patients with ocular toxoplasmosis, although a total absence of the HLA-B51 antigen was found in this group. HLA-A, HLA-B, and HLA-C typing was also performed in their children (52 patients with ocular toxoplasmosis), to investigate a possible relation between the severity of ocular toxoplasmosis and an eventual immunogenetic factor. In the patients with ocular toxoplasmosis an increased frequency of the HLA-Bw62 antigen was observed in correlation with severe ocular involvement. PMID:7612565

    Congenital tracheal stenosis (CTS) is a serious and rare condition. In most cases, stenotic lesions are composed of complete tracheal rings of cartilage.The severity of symptoms correlates with the length of affected trachea, the presence of concomitant respiratory conditions, degree of luminal narrowing,and any bronchial involvement. Critically, CTS is a disorder that can lead to life-threatening respiratory insufficiency in children. Thus, it is a clinical entity that demands timely diagnosis and treatment. This review will firstly discuss the anatomy and pathophysiology of CTS and outline the various clinical presentations associated with the disorder. In addition, methods of diagnosis and treatment strategies will be reviewed, with a focus on contemporary surgical techniques. Finally, postoperative care of patients with CTS will be reviewed, and a contemporary multidisciplinary management approach will be presented.

    Congenital epulis, a benign tumor of the oral cavity, is an extremely rare condition in newborn. It may lead to mechanical obstruction, therefore resulting in respiratory distress and difficulty in feeding. Addressing the problem may need a multidisciplinary team approach at the time of birth. Antenatal ultrasonography and perinatal magnetic resonance imaging are an adjunct to treatment planning. Prenatal diagnosis remains difficult as the findings are nonspecific due to the late development of the tumor. Surgical excision is, therefore, the treatment of choice. Our report discusses this condition and the treatment thereafter on a newborn, with an epulis originating from the upper alveolar ridge discovered at birth. Histological examination confirmed the diagnosis of large polygonal granular cells. The mass was excised under general anesthesia, and the outcome was good after surgery allowing regular feeds on the second postoperative day. PMID:26980979

  4. Congenital craniofacial asymmetry: early treatment.

    PubMed

    Whitaker, L A; Schut, L; Rosen, H M

    1981-01-01

    Congenital craniofacial asymmetry has two dominant causes: isolated synostosis and craniofacial clefts. Treatment considerations in these problems differ from those with isolated cranial or isolated facial defects. Isolated cranial defects are most frequently treated by the neurosurgeon with craniectomy alone. Isolated facial asymmetry when congenital in origin usually manifests as hemifacial microsomia and based on our experience with 40 such patients, is best treated in later childhood. Treatment timing of craniofacial asymmetry varies with the cause, but is best done in the first two years of life. Nasofrontal encephaloceles are usually best treated in the first few weeks of life; synostosis syndromes are treated at six months of age after the facial sutures have had time to stabilize sufficiently for adequate dissection and mobilization; and other craniofacial clefts at approximately two years of age following descent of the teeth and better homeostatic capability of the patient. Based on our series of 58 patients, 40 treated with isolated synostosis at less than one year of age, eight at more than one year of age, and ten patients with craniofacial clefts, the guidelines for timing and methods of treatment have evolved. Liberal use of craniectomy bone with expected regrowth is possible in the first year of life, and more limited use in the second year of life. This bone is used to hold the repositioned orbit, augment hypoplastic zygomas, and reconstruct noses, or for other uses. In isolated synostosis, repositioning provides a form of immediate catch-up growth then proceeds normally. In craniofacial clefts, repositioning puts structures into normal relations and growth likewise proceeds normally. The isolated synostosis syndromes treated at a later age are done with more difficulty, though may be effectively cared for. Complications other than incomplete structural correction have been nonexistent in the group two years of age and less.

  6. Biomarker assessments in asbestos-exposed workers as indicators for selective prevention of mesothelioma or bronchogenic carcinoma: rationale and practical implementations.

    1992-02-01

    In the first part of this study we have shown how the serum levels of four selected tumour markers, namely tissue polypeptide antigen (TPA), carcino-embryonic antigen (CEA), hyaluronic acid (HA) and ferritin, display patterns characteristic of mesothelioma (M) or bronchogenic carcinoma (BC) in asbestos-exposed workers, and we hypothesize that the differences in marker patterns correspond to differences in carcinogenesis mechanisms. In a preliminary study, we found these specific marker patterns in 5/19 exposed workers of whom only one demonstrated any radiological signs of disease. Thus these specific marker patterns may be early events, occurring long (possibly years) before the classical radiological signs of exposure to asbestos. Accordingly they afford an optimal opportunity for prevention which should be adapted to the carcinogenesis mechanism as it is revealed by the marker pattern; it is aimed at antagonizing free radical carcinogenesis in all persons with TPA levels in excess of 100 U/l or Ferritin in excess of 400 ng/ml, and at inhibiting chemical carcinogenesis in those having elevated CEA levels (over 3 ng/ml). The mechanisms involved in these inhibitory processes are described and discussed, as well as the practical implementations that proceed from them. A prevention trial is now being started among 300 active and retired workers of an asbestos-cement works in northern France; the design of the study is presented. This prevention programme should be maintained over many years and holds a strong potential for reducing the untoward effects of exposure to asbestos. PMID:1463974

    Antenatal diagnosis of lung lesion has become more accurate resulting in dilemma and controversies of its antenatal and postnatal management. Majority of antenatally diagnosed congenital lung lesions are asymptomatic in the neonatal age group. Large lung lesions cause respiratory compromise and inevitably require urgent investigations and surgery. The congenital lung lesion presenting with hydrops requires careful postnatal management of lung hypoplasia and persistent pulmonary hypertension. Preoperative stabilization with gentle ventilation with permissive hypercapnia and delayed surgery similar to congenital diaphragmatic hernia management has been shown to result in good outcome. The diagnostic investigations and surgical management of the asymptomatic lung lesions remain controversial. Postnatal management and outcome of congenital cystic lung lesions are discussed.

    OBJECTIVE To emphasize the need of an accurate diagnosis of congenital esophageal stenosis due to tracheobronchial remnants, since its treatment differs from other types of congenital narrowing. CASE DESCRIPTION Four cases of lower congenital esophageal stenosis due to tracheobronchial remnants, whose definitive diagnosis was made by histopathology. Except for the last case, in which a concomitant anti-reflux surgery was not performed, all had a favorable outcome after resection and anastomosis of the esophagus. COMMENTS The congenital esophageal stenosis is an intrinsic narrowing of the organâ€(tm)s wall associated with its structural malformation. The condition can be caused by tracheobronchial remnants, fibromuscular stenosis or membranous diaphragm and the first symptom is dysphagia after the introduction of solid food in the diet. The first-choice treatment to tracheobronchial remnants cases is the surgical resection and end-to-end anastomosis of the esophagus. PMID:24142326

    Increasing numbers of women with complex congenital heart disease are reaching childbearing age. Pregnancy is a major issue in the management of adult congenital heart disease. Cardiac disease is one of the most common causes of maternal morbidity and mortality. Complications, such as growth retardation, preterm and premature birth and even fetal and neonatal mortality, are more frequent among children of women with congenital heart disease. The risk of complications is determined by the severity of the cardiac lesion, the presence of cyanosis, the maternal functional class and the use of anticoagulation. However, the pathophysiology of these complications is not completely understood and may be related to a diminished increase in cardiac output and/or endothelial dysfunction. The management of pregnant cardiac patients is based on limited clinical information. This article reviews pre-pregnancy counseling and management during pregnancy in patients with congenital heart disease.

    Newborn screening for congenital hypothyroidism has been remarkably effective, although rare cases of false negative screening have been reported in same sex twins, presumptively due to fetal blood exchange. We report a case in which the diagnosis of congenital hypothyroidism due to thyroid ectopia in a monozygotic twin was delayed by 8 months, with a normal newborn screening TSH level of 11 mIU/L blood (normal < 15 mIU/L) at 2 days of life. This is the first such case since the national New Zealand newborn screening programme introduced screening for congenital hypothyroidism in 1981 (30 years ago). Repeating thyroid studies at 14 days of age in same-sex twins has been advocated to avoid delayed diagnosis, but given the low risk, may not be cost effective. It is important to maintain a high index of suspicion in same-sex twin pregnancies of potential congenital hypothyroidism. PMID:22970836

    1997-01-01

    When trying to establish the likely anatomical site (preganglionic or postganglionic) of a lesion causing congenital Horner's syndrome, the distribution of facial flushing (the "harlequin" sign), may be seen. In babies and young children, facial flushing is a relatively simple clinical sign to demonstrate, compared with facial sweating. In unilateral facial flushing the areas that do not flush are almost always identical to the anhidrotic areas. However, neither facial flushing nor testing the pupil reactions with pholedrine or hydroxyamphetamine can be relied on to predict the probable site of any lesion causing congenital Horner's syndrome. Two patients with congenital Horner's syndrome are presented which demonstrated the "harlequin" sign and in whom clinical examination and pharmacological testing gave conflicting evidence for localisation of the site of the causative lesion. The presentation of congenital Horner's syndrome should be investigated and include MRI or CT to exclude a serious underlying cause. Images PMID:9219751

    During the last 10 years the interventional treatment of congenital and structural heart diseases has known enormous changes in techniques, methods and patients management. Lesions previously treated surgically are now approached in the catheterization laboratory. The advent of multidisciplinary approach of congenital heart disease has made possible the development of hybrid techniques, of fetal medicine and of magnetic resonance imaging (MRI)- guided cardiac catheterization. Technological innovation has introduced new concepts in treatment of congenital heart disease patients and has allowed to adapt different techniques to single patients. The knowledge of the evolution of structural heart disease has allowed to chose the best percutaneous and/ or surgical technique and the best materials to optimize long term results. Improvement in non invasive imaging modality has allowed to diminish the radiation exposure and to provide useful information to interventional cardiologists and cardiac surgeons. Absorbable, drug eluting tools will change the treatment and probably the natural history of congenital and structural cardiac and vascular diseases.

    With the rapid increase in knowledge on the genetic origin of diseases within the gastrointestinal tract the number of congenital diseases, which already manifest during childhood have drastically increased. Due to the large application of molecular genetics the number is steadily increasing. To make the access to these rare diseases fast and efficient the data base of the National Library of Medicine (Online Mendelian Inheritance of Man - OMIN) is a very helpful online tool, with which all these disease entities can be found easily (http://www.ncbi.nlm.nih.gov/omim). Detailed tables are given to find most of the congenitally inherited disease, which affect the gastrointestinal tract. A variety of congenital diarrheas with disturbances of digestion, hydrolysis, absorption and secretion is described in detail: lactose intolerance, sucrose intolerance, glucose-galactose malabsorption, fructose malabsorption, trehalase and enterokinase deficiency, congenital chloride and sodium diarrhea, congenital hypomagnesaemia, primary bile acid malabsorption, acrodermatitis enteropathica and Menke's syndrome. Also described in detail are diseases with structural anomalies of the intestine like microvillous inclusion disease, congenital tufting enteropathy and IPEX syndrome. The diagnosis in the disturbances of carbohydrate hydrolysis or absorption can be established by H2-breath tests after appropriate sugar challenge. Treatment consists of elimination of the responsible sugar from the diet. The diagnosis of the congenital secretory diarrheas is established by investigation of electrolytes in blood and stool. Substitution of high doses of the responsible mineral can improve the clinical outcome. In acrodermatitis enteropathica low serum zinc level together with the typical skin lesions guide to the diagnosis. High doses of oral zinc aspartate can cure the symptoms of the disease. The diagnosis of structural congenital lesions of the intestine can be established by histology and

  5. Functional Assessment for Congenital Heart Disease

    PubMed Central

    2014-01-01

    Significant improvement in survival of children with congenital cardiac malformations has resulted in an increasing population of adolescent and adult patients with congenital heart disease. Of the long-term cardiac problems, ventricular dysfunction remains an important issue of concern. Despite corrective or palliative repair of congenital heart lesions, the right ventricle, which may be the subpulmonary or systemic ventricular chamber, and the functional single ventricle are particularly vulnerable to functional impairment. Regular assessment of cardiac function constitutes an important aspect in the long-term follow up of patients with congenital heart disease. Echocardiography remains the most useful imaging modality for longitudinal monitoring of cardiac function. Conventional echocardiographic assessment has focused primarily on quantification of changes in ventricular size and blood flow velocities during the cardiac cycles. Advances in echocardiographic technologies including tissue Doppler imaging and speckle tracking echocardiography have enabled direct interrogation of myocardial deformation. In this review, the issues of ventricular dysfunction in congenital heart disease, conventional echocardiographic and novel myocardial deformation imaging techniques, and clinical applications of these techniques in the functional assessment of congenital heart disease are discussed.

    Background Congenital cholesteatoma may be expected in abnormally developed ear, it may cause bony erosion of the middle ear cleft and extend to the infratemporal fossa. We present the first case of congenital cholesteatoma of the infratemporal fossa in a patient with congenital aural atresia that has been complicated with acute mastoiditis. Case presentation A sixteen year old Egyptian male patient presented with congenital cholesteatoma of the infratemporal fossa with congenital aural atresia complicated with acute mastoiditis. Two weeks earlier, the patient suffered pain necessitating hospital admission, magnetic resonance imaging revealed a soft tissue mass in the right infratemporal fossa. On presentation to our institute, Computerized tomography was done as a routine, it proved the diagnosis of mastoiditis, pure tone audiometry showed an air-bone gap of 60 dB. Cortical mastoidectomy was done for treatment of mastoiditis, removal of congenital cholesteatoma was carried out with reconstruction of external auditory canal. Follow-up of the patient for 2 years and 3 months showed a patent, infection free external auditory canal with an air-bone gap has been reduced to 35db. One year after the operation; MRI was done and it showed no residual or recurrent cholesteatoma. Conclusions Congenital cholesteatoma of the infratemporal fossa in cases of congenital aural atresia can be managed safely even if it was associated with mastoiditis. It is an original case report of interest to the speciality of otolaryngology. PMID:22731118

    From the clinical and genetic point of view, congenital muscular dystrophies (CMD) are a heterogenic group of diseases within neuromuscular pathologies. The best known forms are: merosin deficiency CMD, collagen VI deficiency CMD, LMNA-related CMD, selenoprotein-related CMD (SEPN1) and alpha-dystroglycan-related CMD. They present with a broad spectrum of clinical phenotypes. Most of them are transmitted by recessive autosomal inheritance. The initial manifestations very often begin in infancy or in the neonatal period. There are clinical suspicions of the existence of hypotonia and paresis, and they are characterised by a dystrophic pattern in the muscular biopsy (muscle replaced by fibroadipose tissue, with necrosis and cell regeneration). Advances in the understanding of the molecular pathogenesis of CMD have made it possible to make further progress in the classification of the different subtypes. The aim of this review is to comment on the advances made in recent years as regards the classification of CMD in terms of genetics, the proteins involved and their clinical presentation.

  8. Diagnosis of congenital fibrinogen disorders.

    PubMed

    Lebreton, Aurélien; Casini, Alessandro

    2016-08-01

    Congenital fibrinogen disorders comprise quantitative disorders defined by a complete absence (afibrinogenemia) or by a decreased level (hypofibrinogenemia) of circulating fibrinogen and qualitative disorders characterized by a discrepancy between the activity and the antigenic levels of fibrinogen (dysfibrinogenemia and hypodysfibrinogenemia). The biological diagnosis is based on a standard haemostasis assessment. All the coagulation tests that depend on the formation of fibrin as the end point are affected; although in dysfibrinogenemia the specificity and sensitivity of routine test depend on reagent and techniques. A genetic exploration permits to confirm the diagnosis and may enhance the prediction of the patient's phenotype. Homozygous or composite heterozygous null mutations are most often responsible for afibrinogenemia while hypofibrinogenemic patients are mainly heterozygous carrier of an afibrinogenemic allele. Heterozygous missense mutations are prevalent in dysfibrinogenemia, with two hot spot localized in exon 2 of the FGA and in the exon 8 of the FGG. The correlation between phenotype and genotype has been identified in some fibrinogen variants, including six mutations clustered in exons 8 and 9 of the FGG leading to hypofibrinogenemia with hepatic inclusions of abnormal fibrinogen aggregates as well as a few mutations associated with an increase risk of thrombotic events. A familial screening and additional functional assays should be carried out when possible.

    Associations between congenital deafness or blindness and autism have been found. The main consequences of congenital sensory impairment, being barriers for communication, language and social interaction development, may lead to symptoms of autism. To date only few studies have been reported concerning individuals with congenital deafblindness. This study examines symptoms of autism among 71 children with congenital deafblindness using the Autism Behavior Checklist. The cohort of children with congenital deafblindness was found to have symptoms of autism on a level similar to children with another developmental disorder than autism for example intellectual disability. No association was found between severity of congenital sensory impairment and severity or type of symptoms of autism. PMID:24127166

    2011-01-01

    Background Congenital malaria has been considered a rare event; however, recent reports have shown frequencies ranging from 3% to 54.2% among newborns of mothers who had suffered malaria during pregnancy. There are only a few references concerning the epidemiological impact of this entity in Latin-America and Colombia. Objective The aim of the study was to measure the prevalence of congenital malaria in an endemic Colombian region and to determine some of its characteristics. Methods A prospective, descriptive study was carried out in the mothers who suffered malaria during pregnancy and their newborns. Neonates were clinically evaluated at birth and screened for Plasmodium spp. infection by thick smear from the umbilical cord and peripheral blood, and followed-up weekly during the first 21 days of postnatal life through clinical examinations and thick smears. Results 116 newborns were included in the study and 80 umbilical cord samples were obtained. Five cases of congenital infection were identified (four caused by P. vivax and one by P. falciparum), two in umbilical cord blood and three in newborn peripheral blood. One case was diagnosed at birth and the others during follow-up. Prevalence of congenital infection was 4.3%. One of the infected newborns was severely ill, while the others were asymptomatic and apparently healthy. The mothers of the newborns with congenital malaria had been diagnosed with malaria in the last trimester of pregnancy or during delivery, and also presented placental infection. Conclusions Congenital malaria may be a frequent event in newborns of mothers who have suffered malaria during pregnancy in Colombia. An association was found between congenital malaria and the diagnosis of malaria in the mother during the last trimester of pregnancy or during delivery, and the presence of placental infection.

    Improvements in the diagnosis and surgical treatment of congenital heart disease during infancy and childhood have resulted in an outstanding increase in the prevalence of these entities during adulthood. Congenital heart disease in the adult represents a new diagnostic challenge to the consultant cardiologist, unfamiliar with the anatomical and functional complexities of cardiac malformations. Assessment of adult congenital heart disease with imaging techniques can be as accurate as in children. However, these techniques cannot substitute for a detailed clinical assessment. Physical examination, electrocardiography and chest x-rays remain the three main pillars of bedside diagnosis. Transthoracic echocardiography is undoubtedly the imaging technique which provides most information, and in many situations no additional studies are needed. Nevertheless, ultrasound imaging properties in adults are not as favorable as in children, and prior surgical procedures further impair image quality. Despite recent advances in ultrasound technologies such as harmonic or contrast imaging, other diagnostic procedures are sometimes required. Fortunately, transesophageal echocardiography and magnetic resonance imaging are easily performed in the adult, and do not require anaesthetic support, in contrast to pediatric patients. These techniques, together with nuclear cardiology and cardiac catheterization, complete the second tier of diagnostic techniques for congenital heart disease. To avoid unnecessary repetition of diagnostic procedures, the attending cardiologist should choose the sequence of diagnostic techniques carefully; although the information this yields is often redundant, it is also frequently complementary. This article aims to compare the diagnostic utility of different imaging techniques in adult patients with congenital heart disease, both with and without prior surgical repair.

    Congenital cardiopathies are the most frequent congenital malformations. Reports of its prevalence around the world range from 2.1 to 12.3 for every 1000 newborns. Prevalence in our country remains unknown, but it probably occupies sixth place for mortality in infants less than a year old, and third place for mortality in those aged between 1 and 4 years. Based on birthrate, it is calculated that 10 to 12 000 infants in our country have some cardiac malformation. To understand the magnitude of the problem, it is important to identify the global number of newborns with some congenital cardiopathy each year and the type of malformation that they have, in order to determine the necessary resources and to plan their distribution. The main objective of regionalization is the justification of the resources with an emphasis in the specialized medical services to provide the best results for the patients. Hence, reason, based on the resources of each state, as well as their natality and infant mortality rates related to congenital cardiovascular pathology, we should proceed to regionalize the attention, and to simultaneously create a trustworthy database of the congenital cardiopathies. This should have many benefits, such as increase the number of total attended cases, improve the quality of attention, use appropriately the existent resources, and -surely- decrease the infant mortality.

  13. Congenital scoliosis: an up-to-date.

    Congenital scoliosis represents a spinal malformation due to defects of formation, segmentation or mixed ones. It is characterized by a longitudinal and rotational imbalance. 54 patients were analyzed and 39 out of them were operated by various approaches with anterior and posterior instrumentations during 2000 and 2012. The impossibility to appoint some patients encountered in the daily practice into the known classifications, allowed us to purpose two categories of congenital scoliosis related to the predominance of spinal deviances in the coronal and transversal views. No certain etiology of congenital scoliosis has been identified until today. The susceptibility of some polygenic defects is obvious due to the presence of a sum of defects associated to most of the congenital scoliosis cases and the rarity of the presence of a unique defect. The diagnosis requires a thorough clinical and imaging examination in order to establish an individualized therapeutic strategy. The treatment of congenital scoliosis is different from the adolescent idiopathic one. Therapeutic criteria are significantly different. It is essential to assess the difference in growth of the concavity related to the convexity when choosing a particular procedure. The magnitude of the curve and the progressive rate are fundamental issues to the surgeon.

  14. [Congenital heart disease, heterotaxia and laterality].

    Congenital heart disease occurs in about 0,8% of all newborns. Many cardiac malformations occur among relatives and have a polymorphic presentation. The origin of most congenital heart disease is thought to be multifactorial, implying both anomalous expression of genes and the influence of epigenetic factors. However, in a small number of cases, the origin of congenital heart disease has been directly related to chromosomal anomalies or to defects in a single gene. Curiously, defects in a single gene can explain a polymorphic presentation if the anomalous gene controls a basic embryonic process that affects different organs in time and space. Some of these genes appear to control the establishment of laterality. The establishment of the left-right asymmetry starts at the Hensen node. Here, the initial embryonic symmetry is broken by cascades of gene activation that confer specific properties on the left and right sides of the embryo. Although there are variations between species, some basic patterns of gene expression (Nodal, Pitx2) appear to be maintained along the phylogenetic scale. Anomalous expression of these genes induces the heterotaxia syndrome, which usually courses with congenital heart disease. The development of heart malformations is illustrated with the mouse mutant iv/iv, which is a model for the heterotaxia syndrome and the associated congenital heart disease.

  15. Genetic Syndromes associated with Congenital Heart Disease

    PubMed Central

    2015-01-01

    Recent research has demonstrated that genetic alterations or variations contribute considerably to the development of congenital heart disease. Many kinds of genetic tests are commercially available, and more are currently under development. Congenital heart disease is frequently accompanied by genetic syndromes showing both cardiac and extra-cardiac anomalies. Congenital heart disease is the leading cause of birth defects, and is an important cause of morbidity and mortality during infancy and childhood. This review introduces common genetic syndromes showing various types of congenital heart disease, including Down syndrome, Turner syndrome, 22q11 deletion syndrome, Williams syndrome, and Noonan syndrome. Although surgical techniques and perioperative care have improved substantially, patients with genetic syndromes may be at an increased risk of death or major complications associated with surgery. Therefore, risk management based on an accurate genetic diagnosis is necessary in order to effectively plan the surgical and medical management and follow-up for these patients. In addition, multidisciplinary approaches and care for the combined extra-cardiac anomalies may help to reduce mortality and morbidity accompanied with congenital heart disease. PMID:26413101

  16. Newborn screening for congenital hypothyroidism.

    Most neonates born with congenital hypothyroidism (CH) have normal appearance and no detectable physical signs. Hypothyroidism in the newborn period is almost always overlooked and delayed diagnosis leads to the most severe outcome of CH, mental retardation, emphasizing the importance of neonatal screening. Blood spot T4 or TSH or both can be used in neonatal screening for CH. The latter, which is more sensitive, is not cost effective, so the first two are used in different programs in the world. TSH screening was shown to be more specific in the diagnosis of CH; T4 screening is more sensitive in detecting newborns especially with rare hypothalamic-pituitary hypothyroidism, but less specific with a high frequency of false positives mainly in low birth weight and premature infants. The time at which the sample is taken may vary between centers, with the majority taking blood from a heel prick after 24 hours of age to minimize the false positive high TSH due to the physiological neonatal TSH surge that elevates TSH levels and causes dynamic T4 and T3 changes in the first 1 or 2 days after birth. Early discharge of mothers postpartum has increased the ratio of false positive TSH elevations. Although transient hypothyroidism may occur frequently, all suspected infants should be treated as having CH for the first 3 years of life, taking into account the risks of mental retardation. A reevaluation after 3 years is needed in such patients. The goal of initial therapy in CH is to minimize neonatal central nervous system exposure to hypothyroidism by normalizing thyroid function, as reflected by T4 and TSH levels, as rapidly as possible. Iodine deficiency is the most important cause of CH worldwide. Iodine is essential for thyroid hormone synthesis and is present in soil, water and air. Prevention of iodine deficiency can be by iodized salt, iodized oil, iodized bread or iodine tablets. PMID:17220056

    Two infants with congenital rubella defects (congenital rubella syndrome) have been reported from Queensland in 2003, after an increase in rubella in that State in 2001-2002. The national Measles Control Campaign in 1998 aimed to give measles-mumps-rubella (MMR) vaccine to all unvaccinated preschoolers and a second dose to primary schoolchildren. Following the Campaign no children with congenital rubella defects were born to Australian-born mothers during the five years 1998 to 2002, according to reports to the Australian Paediatric Surveillance Unit. However, three imported cases occurred. Broad immunisation coverage and detection and vaccination of susceptible women of child-bearing age before they become pregnant are necessary to prevent further cases.

    Congenital myopathies (CMs), a group of relatively non-progressive disorders presents with weakness and hypotonia of varying severity, morphologically recognized by specific structural abnormalities within the myofiber. This report presents the clinical and Histopathological features of 40 patients with CMs. Centronuclear myopathy was the commonest (40%) followed by congenital fiber type disproportion (37.5%). Other less common CMs included: myotubular myopathy (5%), nemaline myopathy (5%), central core disease (5%), multicore disease (2.5%) and congenital myopathy with tubular aggregate (5%). Immunolabeling to desmin corresponded to morphological changes within the myofibers while vimentin was negative in all the patients. There is no combined role of these proteins in the disease process. PMID:22234203

    2008-12-01

    Identifying the underlying cause of congenital hypotonia remains difficult, despite advances in diagnostic laboratory and imaging techniques. Clinical evaluation strategies and standardized developmental tests can assist in differentiating hypotonia resulting from primary involvement of the upper motoneuron (central hypotonia) versus that involving the lower motoneuron and motor unit (peripheral hypotonia). This is especially important in infants with idiopathic hypotonia. This review outlines and describes the components of the clinical assessment: detailed infant and family history, clinical techniques and characteristics for differentiating hypotonia of central versus peripheral origin, and clinical evaluation (muscle tone, primitive reflexes, deep tendon reflexes, etc). Recent research that has contributed to the differential diagnosis of congenital hypotonia is reviewed and directions for future research are provided. Ideally, the assessment of infants with congenital hypotonia is best accomplished by an interdisciplinary team of developmental specialists including pediatricians, medical geneticists, child neurologists, and physical or occupational therapists.

    This is a retrospective review of congenital cholesteatoma cases that were managed surgically. There were 5 cases. The age of presentation ranged from 5 to 18 year old. Three patients presented with complication of the disease. Three patients had intact tympanic membrane, two had perforation at the anterior superior quadrant. All patients had cholesteatoma medial to tympanic membrane. Four cases had extensive ossicular erosion with preoperative hearing worse than 40 dB. Four cases underwent canal wall down mastoid surgery and one underwent canal wall up surgery. One patient had recurrence which required revision surgery. In conclusion, congenital cholesteatoma presented late due to the silent nature of disease in its early stage. Extensive disease, ossicular destruction with risk of complication at presentation were marked in our study. Hence, more aggressive surgical intervention is recommended in the management of congenital cholesteatoma. PMID:21939167

    Introduction Congenital heart disease is an abnormality in the structure or cardiocirculatory function, occurring from birth, even if diagnosed later. It can result in intrauterine death in childhood or in adulthood. Accounted for 6% of infant deaths in Brazil in 2007. Objective To estimate underreporting in the prevalence of congenital heart disease in Brazil and its subtypes. Methods The calculations of prevalence were performed by applying coefficients, giving them function rates for calculations of health problems. The study makes an approach between the literature and the governmental registries. It was adopted an estimate of 9: 1000 births and prevalence rates for subtypes applied to births of 2010. Estimates of births with congenital heart disease were compared with the reports to the Ministry of Health and were studied by descriptive methods with the use of rates and coefficients represented in tables. Results The incidence in Brazil is 25,757 new cases/year, distributed in: North 2,758; Northeast 7,570; Southeast 10,112; South 3,329; and Midwest 1,987. In 2010, were reported to System of Live Birth Information of Ministry of Health 1,377 cases of babies with congenital heart disease, representing 5.3% of the estimated for Brazil. In the same period, the most common subtypes were: ventricular septal defect (7,498); atrial septal defect (4,693); persistent ductus arteriosus (2,490); pulmonary stenosis (1,431); tetralogy of Fallot (973); coarctation of the aorta (973); transposition of the great arteries (887); and aortic stenosis 630. The prevalence of congenital heart disease, for the year of 2009, was 675,495 children and adolescents and 552,092 adults. Conclusion In Brazil, there is underreporting in the prevalence of congenital heart disease, signaling the need for adjustments in the methodology of registration. PMID:26107454

    The diagnosis of congenital and acquired bleeding disorders in infants requires an understanding of developmental haemostasis and the effect on laboratory testing. A systematic approach to bleeding in neonates will aid clinicians in the diagnosis and treatment, which may be caused by a wide variety of diseases. The clinical setting will help to direct the diagnostic pathway. This review will focus on the presentation and diagnosis of congenital and acquired bleeding disorders, including platelet disorders. Current research in this field is ongoing, including investigation into neonatal platelets and their different functionalities, platelet transfusion thresholds and how changes in coagulation factors may be linked to other homeostatic mechanisms.

    Congenital anophthalmia is the result of a lack of development or regression of the primary optic vesicle in utero. It can be isolated or associated with other malformations and can be unilateral or, rarely, bilateral. Different etiologies are usually found such as chromosomal aberrations, gene mutations, toxic agents, and infections. We report a case of bilateral congenital anophthalmia in a setting of a polymalformative syndrome with microcephalia and bilateral lip cleft. Karyotype studies confirmed trisomy 13 known as Patau's syndrome. Trisomy 13 is a rare lethal chromosomal aberration frequently responsible for uni- or bilateral microphthalmia and occasionally for anophthalmia.

    We report three cases of congenital absence of an internal carotid artery (ICA), diagnosed incidentally by digital subtraction angiography. The analysis of the cases is based on the classification of segmental ICA agenesis proposed by Lasjaunias and Berenstein. Usually the patients with this rare vascular anomaly are asymptomatic; some may have symptoms related to cerebrovascular insufficiency, compression by enlarged intracranial collateral vessels, or complications associated with cerebral aneurysms. Diagnosis of congenital absence of ICA is made by skull base computed tomography (CT) scan, CT and magnetic resonance angiography, and conventional or digital subtraction angiography.

    Because lead crosses the placenta throughout pregnancy, the fetus is at risk for lead poisoning. A full term, asymptomatic child was born with congenital lead poisoning secondary to maternal pica. Radiographic findings of a dense cranial vault, lead lines, and delayed skeletal and deciduous dental development were noted at birth. After chelation therapy, when the patient was seven months old, radiographs revealed normal skeletal maturation. Tooth eruption did not occur until 15 months of age. Newborn infants with these radiographic findings should be screened for subclinical, congenital lead poisoning.

    Congenital fibrosarcomas are malignant tumors that arise in soft tissues. In infants this unique tumor does not commonly metastasize, even though there may be local recurrences. We report here a boy who had congenital fibrosarcoma in his right foot, which was completely excised at the age of 3 days. Four months later, a solitary encapsulated metastasis emerged in thoracic chest wall, which was operated. During adjuvant chemotherapy he developed histologically confirmed fibrosarcoma metastases in the heart. After extended treatment with cyclophosphamide/topotecan and gemcitabine/docetaxel, the heart tumors disappeared and he has been in complete remission for 3 years.

    A unique case of a congenital skin fossa in the zygomatic region in a 3-year-old girl is reported. Little has been written about congenital fossae, or dimples. They are thought to develop in the wound resulting from the fetal tissue being compressed between a sharp bony point and the uterine wall. The skin and subcutaneous tissue become compressed and adherent, and when the pressure is released, surrounding parts can stand up, while the attached part remains tied down, forming small dimples or fossae, what have been called "pressure dimples." This is the first report of a skin fossa located in the zygomatic region, as far as we know. PMID:8416522

    Congenital diseases of the aorta tend to be obstructive when they present early in life, and aneurysmal when they present later in life. The latter group also tends to be associated with connective tissue disorders and with repaired conotruncal lesions. The indications for intervention in the aneurysm group are still in evolution but are clearly age- and lesion-dependant. Disorders such as Loeys-Dietz syndrome and Turner syndrome may deserve aggressive prophylactic surgery, as well as Marfan syndrome to a lesser extent. The natural history of the dilated aorta after repair of congenital heart lesions is probably more benign than de novo aneurysms and therefore should be treated conservatively.

    Congenital diaphragmatic Bochdaleck hernia is an anatomical defect of the diaphragm, which allows protrusion of abdominal viscera into the chest, causing serious pulmonary and cardiac complications in the neonate. In this study we aimed to present a case of congenital Bochdaleck hernia. We investigated a 40 weeks old child, with a pregnancy carried out in a public hospital in Passo Fundo, Rio Grande do Sul, Brazil. We suggest that if diagnosis occurs in the prenatal period, the prognosis of this disease improves. As a consequence, it allows the parity of the fetus to occur in a higher complexity center, optimizing the chances of survival. PMID:23110948

    Congenital heart disease (CHD) is the most common form of congenital anomaly. Prenatal diagnosis of CHD has been associated with decreased morbidity and mortality for some forms of major CHD. As most cases of major CHD are not identified prenatally, clinical examination of the newborn and pulse oximetry are also important means of identifying more cases. Clinicians must suspect CHD as a diagnosis in a cyanosed or shocked neonate and be familiar with appropriate management, namely the commencement of prostaglandin if a duct dependent cardiac lesion is suspected. Telemedicine can aid prompt diagnosis of CHD and therefore direct appropriate management. PMID:25484461

Each child had clinical and electrodiagnostic features consistent with an inherited neuropathy, confirmed by sural nerve biopsy. The cases illustrate the clinically heterogeneity that exists even within early-onset forms of this disease. They also lend additional support to the emerging clinical and laboratory evidence that impaired intracellular protein trafficking may represent the cause of some congenital hypomyelinating neuropathies.

    Congenital patellar dislocation is a rare condition in which the patella is permanently dislocated and cannot be reduced manually. The patella develops normally as a sesamoid bone of the femur. This congenital dislocation results from failure of the internal rotation of the myotome that forms the femur, quadriceps muscle and extensor apparatus. It usually manifests immediately after birth, although in some rare cases, the diagnosis may be delayed until adolescence or adulthood. Early diagnosis is important, thereby allowing surgical correction and avoiding late sequelae, including early degenerative changes in the knee. A case of permanent dislocation of the patella is presented here, in a female child aged seven years.

    Congenital malformations frequently arise sporadically, making it difficult to determine whether or not they are genetic in aetiology, let alone which gene(s) may be involved. Nevertheless, rapid progress has been made over recent years in the localisation and identification of gene mutations in specific malformations. This review draws from Mendelian inheritance in man (Johns Hopkins University Press, 11th ed, 1994) and the online version (OMIM) to catalogue 139 loci (including 65 specifically identified genes) implicated in congenital malformations. Some of the most interesting recent developments are discussed. PMID:7966186

    Congenital malalignment is the lateral deviation of the nail plate along the longitudinal axis due to the lateral rotation of the nail matrix. The nail plate grows out in ridges caused by repeated microtrauma to the nail. Common complications include onychomycosis, Pseudomonas infection and acute or chronic paronychia. Treatment options range from conservative management to surgical options including realignment and nail matrixectomy. Congenital malalignment usually presents in infancy or childhood, but we present two cases of acquired malalignment occurring in the teenage years. PMID:27171597

Using Ishihara pseudoisochromatic plates, 941 healthy men from the Turkish army were tested for congenital red-green color blindness. The prevalence of red-green color blindness was 7.33 +/- 0.98% (5.10% protans and 2.23% deutans). These ratios were higher than other reported samples from Mediterranean Europe. Higher percentages of color blindness were found in regions with a lower education level and more consanguineous marriages.

    Congenital self-healing reticulohistiocytosis is a rare, congenital, benign, self-healing variant of Langerhans cell histiocytosis. It usually appears as multiple papules or nodules; however, occurrence of the solitary type is very rare. We report on a case of solitary congenital self-healing reticulohistiocytosis in a 29-day-old girl who presented with a papule on her sole. Two months later, the lesion regressed with a slight scar. Based upon clinical and histologic findings, we made a diagnosis of solitary congenital self-healing reticulohistiocytosis. In this report, we summarized reported cases of solitary congenital self-healing retioculohistiocytosis in Korea with a review of the literature. PMID:22028569

    2016-01-01

    Congenital hearing impairment affects nearly 1 in every 1000 live births and is the most frequent birth defect in developed societies. Hereditary types of hearing loss account for more than 50% of all congenital sensorineural hearing loss cases and are caused by genetic mutations. HL can be either nonsyndromic, which is restricted to the inner ear, or syndromic, a part of multiple anomalies affecting the body. Nonsyndromic HL can be categorised by mode of inheritance, such as autosomal dominant (called DFNA), autosomal recessive (DFNB), mitochondrial, and X-linked (DFN). To date, 125 deafness loci have been reported in the literature: 58 DFNA loci, 63 DFNB loci, and 4 X-linked loci. Mutations in genes that control the adhesion of hair cells, intracellular transport, neurotransmitter release, ionic hemeostasis, and cytoskeleton of hair cells can lead to malfunctions of the cochlea and inner ear. In recent years, with the increase in studies about genes involved in congenital hearing loss, genetic counselling and treatment options have emerged and increased in availability. This paper presents an overview of the currently known genes associated with nonsyndromic congenital hearing loss and mutations in the inner ear. PMID:26989561

    A 2-week-old crossbred male piglet with numerous congenital, variably sized macules, plaques, and papules distributed all over the body was submitted for necropsy. Significant gross and histological lesions were restricted to the skin. On light microscopic examination, these cutaneous lesions corresponded to dermal and/or subcutaneous masses composed of spindle-shaped to round cells that multifocally contained hemosiderin; epidermotropism was not observed. Immunohistochemically, the neoplastic cells were strongly positive for CD204; moderately positive for CD163, lysozyme, and vimentin; and negative for Mac 387, α-1-antitrypsin, S-100 protein and E-cadherin; frozen tissues were not available for CD1a and CD11c. Transmission electron microscopic examination of sections from formalin-fixed tissues did not reveal Birbeck's granules. The clinical, morphological, and immunohistochemical results were consistent with a congenital cutaneous histiocytosis of non-Langerhans cell origin. The condition most resembled juvenile xanthogranuloma in humans, a generally skin-limited non-Langerhans histiocytic disorder that can be congenital. Cutaneous and/or systemic histiocytic disorders are well characterized in dogs and have been described in cats, and a case with some similarities to ours has been reported in a neonatal piglet, but this is to our knowledge the first immunohistochemically supported report of histiocytosis in the pig and congenital histiocytosis in animals.

    Diagnosing the cause of bovine congenital malformations (BCMs) is challenging for bovine veterinary practitioners and laboratory diagnosticians as many known as well as a large number of not-yet reported syndromes exist. Foetal infection with certain viruses, including bovine virus diarrhea virus (BVDV), Schmallenberg virus (SBV), blue tongue virus (BTV), Akabane virus (AKAV), or Aino virus (AV), is associated with a range of congenital malformations. It is tempting for veterinary practitioners to diagnose such infections based only on the morphology of the defective offspring. However, diagnosing a virus as a cause of BCMs usually requires laboratory examination and even in such cases, interpretation of findings may be challenging due to lack of experience regarding genetic defects causing similar lesions, even in cases where virus or congenital antibodies are present. Intrauterine infection of the foetus during the susceptible periods of development, i.e. around gestation days 60-180, by BVDV, SBV, BTV, AKAV and AV may cause malformations in the central nervous system, especially in the brain. Brain lesions typically consist of hydranencephaly, porencephaly, hydrocephalus and cerebellar hypoplasia, which in case of SBV, AKAV and AV infections may be associated by malformation of the axial and appendicular skeleton, e.g. arthrogryposis multiplex congenita. Doming of the calvarium is present in some, but not all, cases. None of these lesions are pathognomonic so diagnosing a viral cause based on gross lesions is uncertain. Several genetic defects share morphology with virus induced congenital malformations, so expert advice should be sought when BCMs are encountered.

    Abstract Introduction: Fast-growing congenital hepatic cysts with intracystic hemorrhage are rare in clinical practice. Additionally, the clinical manifestations of and laboratory and imaging findings for this condition are often nonspecific and are particularly difficult to differentiate from those of hepatobiliary cystadenoma and cystadenocarcinoma, thus posing great challenges for diagnosis and treatment. The 2 case reports presented here aim to analyze the diagnosis and treatment of 2 rare cases of congenital hepatic cysts with intracystic hemorrhage in the Chinese Han population to provide an important reference for the clinical diagnosis and treatment of this condition. Diagnoses: These 2 case reports present 2 rare cases of congenital hepatic cysts with intracystic hemorrhage. Case 1 involved a 31-year-old patient with a very large, fast-growing hepatic cyst with intracystic hemorrhage and elevated carbohydrate antigen 199. Case 2 involved a patient with intense, paroxysmal right upper abdominal pain; computed tomography suggested a hepatic cyst with intracystic hemorrhage and possibly hepatobiliary cystadenoma. Outcomes: Both patients underwent liver resection. Postoperative follow-up showed that for both patients, the symptoms improved, the laboratory findings returned to normal levels, and the surgical outcomes were satisfactory. Conclusion: Liver resection is an ideal treatment for patients with congenital hepatic cysts with intracystic hemorrhage, and especially those with fast-growing, symptomatic hepatic cysts or hepatic cysts that are difficult to differentiate from hepatobiliary cystadenoma and cystadenocarcinoma.

    2009-01-01

    Evidence that prevention, diagnosis and treatment of toxoplasmosis is beneficial developed as follows: antiparasitic agents abrogate Toxoplasma gondii tachyzoite growth, preventing destruction of infected, cultured, mammalian cells and cure active infections in experimental animals, including primates. They treat active infections in persons who are immune-compromised, limit destruction of retina by replicating parasites and thereby treat ocular toxoplasmosis and treat active infection in the fetus and infant. Outcomes of untreated congenital toxoplasmosis include adverse ocular and neurologic sequelae described in different countries and decades. Better outcomes are associated with treatment of infected infants throughout their first year of life. Shorter intervals between diagnosis and treatment in utero improve outcomes. A French approach for diagnosis and treatment of congenital toxoplasmosis in the fetus and infant can prevent toxoplasmosis and limit adverse sequelae. In addition, new data demonstrate that this French approach results in favorable outcomes with some early gestation infections. A standardized approach to diagnosis and treatment during gestation has not yet been applied generally in the USA. Nonetheless, a small, similar experience confirms that this French approach is feasible, safe, and results in favorable outcomes in the National Collaborative Chicago-based Congenital Toxoplasmosis Study cohort. Prompt diagnosis, prevention and treatment reduce adverse sequelae of congenital toxoplasmosis. PMID:19430661

    2016-01-01

    The association between congenital facial paralysis and visual development has not been thoroughly studied. Of 27 pediatric cases of congenital facial paralysis, we identified 3 patients who developed amblyopia, a visual acuity decrease caused by abnormal visual development, as comorbidity. These 3 patients had facial paralysis in the periocular region and developed amblyopia on the paralyzed side. They started treatment by wearing an eye patch immediately after diagnosis and before the critical visual developmental period; all patients responded to the treatment. Our findings suggest that the incidence of amblyopia in the cases of congenital facial paralysis, particularly the paralysis in the periocular region, is higher than that in the general pediatric population. Interestingly, 2 of the 3 patients developed anisometropic amblyopia due to the hyperopia of the affected eye, implying that the periocular facial paralysis may have affected the refraction of the eye through yet unspecified mechanisms. Therefore, the physicians who manage facial paralysis should keep this pathology in mind, and when they see pediatric patients with congenital facial paralysis involving the periocular region, they should consult an ophthalmologist as soon as possible.

    PubMed Central

    2014-01-01

    Background Control programs have been executed in an attempt to reduce vertical transmission and the severity of congenital infection in regions with a high incidence of toxoplasmosis in pregnant women. We aimed to evaluate whether treatment of pregnant women with spiramycin associated with a lack of monitoring for toxoplasmosis seroconversion affects the prognosis of patients. Methods We performed a prospective cohort study with 246 newborns (NB) at risk for congenital toxoplasmosis in Goiânia (Brazil) between October 2003 and October 2011. We analyzed the efficacy of maternal treatment with spiramycin. Results A total of 40.7% (66/162) of the neonates were born seriously infected. Vertical transmission associated with reactivation during pregnancy occurred in 5.5% (9/162) of the NB, with one showing severe infection (systemic). The presence of specific immunoglobulins (fetal IgM and NB IgA) suggested the worst prognosis. Treatment of pregnant women by spiramycin resulted in reduced vertical transmission. When infected pregnant women did not undergo proper treatment, the risk of severe infection (neural-optical) in NB was significantly increased. Fetal IgM was associated with ocular impairment in 48.0% (12/25) of the fetuses and neonatal IgA-specific was related to the neuro-ophthalmologic and systemic forms of the disease. When acute toxoplasmosis was identified in the postpartum period, a lack of monitoring of seronegative pregnant women resulted in a higher risk of severe congenital infection. Conclusion Treatment of pregnant women with spiramycin reduces the possibility of transmission of infection to the fetus. However, a lack of proper treatment is associated with the onset of the neural-optical form of congenital infection. Primary preventive measures should be increased for all pregnant women during the prenatal period and secondary prophylaxis through surveillance of seroconversion in seronegative pregnant woman should be introduced to reduce the

    Here we describe the first documented case of congenital amusia in childhood. AS is a 10-year-old girl who was referred to us by her choir director for persisting difficulties in singing. We tested her with the child version of the Montreal Battery for the Evaluation of Amusia (MBEA) which confirmed AS's severe problems with melodic and rhythmic discrimination and memory for melodies. The disorder appears to be limited to music since her audiometry as well as her intellectual and language skills are normal. Furthermore, the musical disorder is associated to a severe deficit in detecting small pitch changes. The electrical brain responses point to an anomaly in the early stages of auditory processing, such as reflected by an abnormal mismatch negativity (MMN) response to small pitch changes. In singing, AS makes more pitch than time errors. Thus, despite frequent and regular musical practice, AS's profile is similar to the adult form of congenital amusia. PMID:21453912

    Six cases of full spontaneous closure of congenital coronary artery fistulas, and one case of near closure, as seen by colour Doppler echocardiography, are presented. It is worth reconsidering the classical view that nearly all cases of spontaneous closure are eligible for surgical or percutaneous correction to prevent the development of significant and potentially fatal complications. As the natural course of coronary artery fistulas is still poorly defined, asymptomatic patients, especially those under 7 years old with small shunts, should be periodically followed up by echocardiography rather than be subjected to operative closure, even by catheterisation.

    1989-01-01

    A typical case of congenital laryngo-trachea-esophageal cleft (LTEC) is presented with a Review of the literature. LTEC is a rare congenital anomaly caused by defective fusion of the septum between larynx/trachea and hypopharynx/esophagus. The septum is formed by fusion of two lateral folds growing medially in very early foetal life. Fusion progresses in a cranial direction. Disturbances in septum formation result in LTEC. The disease gives respiratory problems with aspiration and excessive salivary production. The diagnosis is best made by intubating the larynx and examining the postcricoid region and anterior wall of the esophagus endoscopically. Stapling of the stomach, tracheostomy and secondary operative closure of the cleft has proved effective in the treatment of LTEC. PMID:2911891

    2008-09-01

    Congenitally deaf infants and children commonly suffer vestibular failure in both ears, and impairment of postural control, locomotion, and gait. The development of gross motor functions, such as head control, sitting, and walking is likely to be delayed, but fine motor function is usually preserved unless disorders of the central nervous system are present. These children can eventually catch up with their normal peers in terms of development and growth as a result of central vestibular compensation. The visual and somatosensory systems, pyramidal and extrapyramidal motor system (cerebellum, basal ganglia, cerebrum) and intellectual development, compensate for vestibular failure in infants and children with congenitally hypoactive or absent function of the semicircular canals and otolith organs.

    BACKGROUND--Congenital anophthalmos is a rare condition in which intervention at an early age can stimulate orbital expansion and maximise facial symmetry. Much is still unknown, however, regarding the degree of soft tissue and bony orbital growth achieved using the orbital expanders presently available. METHODS--A retrospective review of 59 congenitally anophthalmic orbits in 42 patients was carried out. RESULTS--The soft tissue and bony orbital expansion achieved using serial solid shapes is reported, and experience with hydrophilic expanders and inflatable silicone expanders is reviewed. CONCLUSION--Although serially fitted solid shapes in the orbit lead to increased expansion of orbital soft tissue and bone compared with no orbital implant, further orbital tissue enlargement is required. The inflatable silicone expander may allow more rapid and extensive orbital tissue expansion, but design changes are needed to achieve this. PMID:7662633

    2012-01-01

    Congenital and idiopathic scoliosis represent disabling conditions of the spine. While congenital scoliosis (CS) is caused by morphogenic abnormalities in vertebral development, the cause(s) for idiopathic scoliosis is (are) likely to be varied, representing alterations in skeletal growth, neuromuscular imbalances, disturbances involving communication between the brain and spine, and others. Both conditions are characterized by phenotypic and genetic heterogeneities, which contribute to the difficulties in understanding their genetic basis that investigators face. Despite the differences between these two conditions there is observational and experimental evidence supporting common genetic mechanisms. This paper focuses on the clinical features of both CS and IS and highlights genetic and environmental factors which contribute to their occurrence. It is anticipated that emerging genetic technologies and improvements in phenotypic stratification of both conditions will facilitate improved understanding of the genetic basis for these conditions and enable targeted prevention and treatment strategies.

    2015-01-01

    The congenital myasthenic syndromes are diverse disorders linked by abnormal signal transmission at the motor endplate that stem from defects in single or multiple proteins. Multiple endplate proteins are affected by mutations of single enzymes required for protein glycosylation, and deletion of PREPL exerts its effect by activating adaptor protein 1. Finally, neuromuscular transmission is also impaired in some congenital myopathies. The specific diagnosis of some syndromes is facilitated by clinical clues pointing to a disease gene. In absence of such clues, exome sequencing is a useful tool for finding the disease gene. Deeper understanding of disease mechanisms come from structural and in vitro electrophysiologic studies of the patient endplate, and from engineering the mutant and wild-type gene into a suitable expression system that can be interrogated by appropriate electrophysiologic and biochemical studies. Most CMS are treatable. Importantly, however, some medication beneficial in one syndrome can be detrimental in another. PMID:25792100

The patients showed clinically prominent features described by Ullrich, i.e. congenital muscle weakness, hypotonia, and hyperextensibility of distal joints, contractures of proximal joints, high-arched palate, hyperhidrosis, posterior protrusion of calcaneus, and no progression. Muscle biopsies revealed dystrophic changes. Ullrich suggested that this condition was a new entity, but the disease has received little attention. In the present cases superior intelligence and tendency to recurrent upper respiratory tract infections were stressed as characteristics of this disorder. Insufficient cellular immunity was suspected and this may contribute to the recurrent upper respiratory tract infections and pneumonia often observed. This disease is considered a distinct entity of multisystemic involvement inherited as an autosomal recessive trait. Images PMID:604494

The number of patients, with and without surgery is growing up rapidly. Conservatively speaking, there are in Mexico approximately 300 thousands patients with this condition, increasing by 15 thousands patients per year. In addition to the complexity of the congenital pathology, the knowledge of acquired diseases should be incorporated as well as the genetic advise, pregnancy care and specialized psychological support.

    The children with congenital heart disease are faced with a series of procedures in chronological sequence. Throughout this process the infant and their parents require timely information, education and preparation for discharge. However, the information about each of the aspects affected by the disease is usually addressed in isolation by different professionals and not as part of a comprehensive educational program. The educational program should consider the nature of the disease, of the users and educators during their planning and must be implemented by a multidisciplinary team, continuously during hospitalization and follow-up, using various teaching methods available, and incorporating the minimum content described in the literature. The objective of this review is to identify the dimensions and key elements to consider in the design of an educational program for parents of children with congenital heart disease based on the model of Kaufman.

    Congenital cytomegalovirus (CMV) is a leading cause of permanent disability in children. The main source of maternal infection is from contact with young children. Primary maternal infection is diagnosed with demonstration of seroconversion or a positive CMV IgM in combination with a low-avidity CMV IgG. Fetal infection may be diagnosed with amniotic fluid polymerase chain reaction and culture. CMV-specific hyperimmune globulin has shown promise as a possible means to prevent congenital infection; large randomized trials are ongoing. To date, the only effective means of prevention is through reducing exposure to the virus. Rates of maternal infection may be reduced through education regarding sources of infection and improved hygiene.

    Congenital lobar emphysema (CLE) is a rare but life-threatening congenital anomaly leading to respiratory distress in early childhood. Diagnosis requires a strong clinical suspicion. We report a case of a 31/2-month-old infant who was initially diagnosed with pneumonia requiring multiple hospital admissions. After computed tomography of the thorax, a diagnosis on CLE was made. The child was planned for surgery in the next available routine operation theatre. However, suddenly in the evening, she developed respiratory distress and needed emergency surgical intervention. The child improved dramatically after surgery, and the postoperative period was uneventful. Early diagnosis and treatment in such cases can lead to dramatic results. PMID:27185998

    The incidence of divorce or legal separation was studied in 438 families of children born with heart disease who entered the New England Regional Infant Cardiac Program between 1968 and 1973. The parents were interviewed when the children were 5 1/2 years old. The rate of divorce in 438 families of children with critical congenital heart disease was not significantly different from the rate in two comparison groups: (1) 25 families of children whose cardiac defect was spontaneously cured, and (2) 26 families of children catheterized in infancy for suspected cardiac defect but who were found to be free of heart disease.

    Five children aged between 9 months and 7 years were admitted to hospital each with an unsuspected congenital diaphragmatic hernia. In 4 the diagnosis was pneumonia with a secondary pleural effusion or lung abscess. Initial investigations were unhelpful to the admitting physician; two of the children had had a previous chest x-ray which was normal. For 3 children the correct diagnosis was only made at necropsy. It is suggested that the possibility of a congenital diaphragmatic hernia be considered in any patient who has an indefinable diaphragm and cystic lesion on his chest x-ray film. Barium studies with the patient in Trendelenburg's position are of value in excluding the presence of bowel in the chest. Images Fig. 1 Fig. 2 PMID:7247437

    The frequency and importance of the evaluation of the posterior fossa have increased significantly over the past 20 years owing to advances in neuroimaging. Nowadays, conventional and advanced neuroimaging techniques allow detailed evaluation of the complex anatomic structures within the posterior fossa. A wide spectrum of congenital abnormalities has been demonstrated, including malformations (anomalies due to an alteration of the primary developmental program caused by a genetic defect) and disruptions (anomalies due to the breakdown of a structure that had a normal developmental potential). Familiarity with the spectrum of congenital posterior fossa anomalies and their well-defined diagnostic criteria is crucial for optimal therapy, an accurate prognosis, and correct genetic counseling. The authors discuss the spectrum of posterior fossa malformations and disruptions, with emphasis on neuroimaging findings (including diagnostic criteria), neurologic presentation, systemic involvement, prognosis, and risk of recurrence.

    Introduction: Identification of the NPHS1 gene, which encodes nephrin, was followed by many studies demonstrating its mutation as a frequent cause of congenital nephrotic syndrome (CNS). While this gene is found in 98% of Finnish children with this syndrome, non-Finnish cases have lower level of incidence ranging from 39 to 80%. Case report: This report describes the clinical presentation of a two-week-old neonate who presented with periorbital and lower extremities edema, abdominal distention, heavy proteinuria, serum hypoproteinemia and failure to thrive. Genetic analysis revealed NHPS1 gene mutation leading to CNS-Finnish type diagnosis. Conclusion: Through this case we want to create awareness about diagnosis and treatment challenges in developing countries for rare congenital diseases. PMID:27594755

    This study was conducted on 500 full-term neonates and 25 older patients with congenital hypothyroidism (CH), newly or previously diagnosed. Alphafetoprotein (AFP) was elevated in two neonates. In one, persistent elevation of AFP and thyroid stimulating hormone (TSH) with low thyroxine (T4) were found (congenital hypothyroidism). In the other, AFP, TSH and T4 levels normalized (transient hypothyroidism). The mean AFP level in new CH patients was significantly higher than in previously diagnosed patients, and was higher in CH patients than in controls. Significant relationships were found between AFP and T4, AFP and TSH, and AFP and age. AFP is a sensitive indicator of thyroid status and can be used as a screening test for hypothyroidism from the first day of life and in follow-up of CH patients.

    Congenital malalignment of the great toenail (CMA) is a disorder of the anatomic orientation of the ungual apparatus, in which the longitudinal axis of the nail plate is not parallel with the axis of the distal phalanx but is deflected sideways. This disorder is understood to arise from multiple factors. Although many theories have been proposed about its origin, its pathogenesis is not fully known. Besides the cosmetic impact, this disorder causes such problems in the medium and long term as onychocryptosis and difficulty in motion. Some cases may regress spontaneously, although persistent cases may require a specialized surgical approach. Congenital malalignment of the great toenail is poorly understood and described medical condition that is often treated incorrectly; thus, reviewing the subject is important. A symptombased clinical classification system is proposed to guide diagnosis and treatment modality decisions.

    Three patients who appear to have a previously undescribed congenital neuropathy are described. None is of Ashkenazi Jewish extraction, but each seems to fulfill the clinical diagnostic criteria for familial dysautonomia. All lack overflow tears, fungiform papillae, and deep-tendon reflexes; intradermal administration of histamine did not produce an axon flare. Intraocular instillation of dilute mecholyl produced miosis in the one patient tested. In contrast to patients with familial dysautonomia, the three patients had universal loss of pain sensation, profound hypotonia, and unusual facies. Pathologic examination of the sural nerve in one patient was not consistent with the usual findings in familial dysautonomia. These patients are believed to have a previously undescribed congenital neuropathy.

    Most women with known congenital heart disease can have successful pregnancy, labor, and delivery. Preconception assessment is essential in understanding anatomy, repairs, and current physiology, all of which can influence risk in pregnancy. With that foundation, a multidisciplinary cardio-obstetric team can predict and prepare for complications that may occur with superimposed hemodynamic changes of pregnancy. Individuals with Eisenmenger syndrome, pulmonary hypertension, cyanosis, significant left heart obstruction, ventricular dysfunction, or prior major cardiac event are among the highest risk for complications.

    The surgery and management of children who have congenital malformations of the skull and meninges require multidisciplinary care and long-term follow-up by multiple specialists in birth defects. The high definition of three-dimensional CT and MRI allows precise surgery planning of reconstruction and management of associated malformations. The reconstruction of meningoencephaloceles and craniosynostosis are challenging procedures that transform the child's appearance. The embryology, clinical presentation, and surgical management of these malformations are reviewed.

    Diagnosing the cause of bovine congenital malformations (BCMs) is challenging for bovine veterinary practitioners and laboratory diagnosticians as many known as well as a large number of not-yet reported syndromes exist. Foetal infection with certain viruses, including bovine virus diarrhea virus (BVDV), Schmallenberg virus (SBV), blue tongue virus (BTV), Akabane virus (AKAV), or Aino virus (AV), is associated with a range of congenital malformations. It is tempting for veterinary practitioners to diagnose such infections based only on the morphology of the defective offspring. However, diagnosing a virus as a cause of BCMs usually requires laboratory examination and even in such cases, interpretation of findings may be challenging due to lack of experience regarding genetic defects causing similar lesions, even in cases where virus or congenital antibodies are present. Intrauterine infection of the foetus during the susceptible periods of development, i.e. around gestation days 60-180, by BVDV, SBV, BTV, AKAV and AV may cause malformations in the central nervous system, especially in the brain. Brain lesions typically consist of hydranencephaly, porencephaly, hydrocephalus and cerebellar hypoplasia, which in case of SBV, AKAV and AV infections may be associated by malformation of the axial and appendicular skeleton, e.g. arthrogryposis multiplex congenita. Doming of the calvarium is present in some, but not all, cases. None of these lesions are pathognomonic so diagnosing a viral cause based on gross lesions is uncertain. Several genetic defects share morphology with virus induced congenital malformations, so expert advice should be sought when BCMs are encountered. PMID:26399846

    Congenital Muscular Torticollis (CMT) is a postural deformity of head and neck detected at birth or shortly after birth, primarily resulting from unilateral shortening of Sternocleidomastoid Muscle (SCM). In neonates and infants, patient may cure conservatively by physiotherapy but surgery is the treatment of choice for children and adolescents. There are various techniques of surgery. Here we show our experience regarding management of congenital muscular torticollis. In the present retrospective case series, fourteen patients of congenital muscular torticollis were treated. The cases were enrolled between Nov' 2005 to Oct' 2007 in Bangabandhu Sheikh Mujib Medical University, Gonosasthaya Somaj Vittik Medical College Hospital, Dhaka and different private clinics of Dhaka city of Bangladesh. Neonates and infants were treated conservatively with physiotherapy and others treated surgically by transection of both sternal and clavicular head of SCM under general anesthesia. Operated patients were released on following post operative day with advised to do physiotherapy. Patients age range from 7 days to 15 years of which ten were female and four male. SCM was shortened in all cases (8 on right side and 6 on left side). Eleven were female and three male. Of 14 patients, 2 neonates, 7 infants and 5 were more than 1 year age. There was no associated anomaly. Out of 9 neonates and infants 8 cured conservatively with physiotherapy and another one significantly improved. Six were treated surgically including one failed physiotherapy. Post operative period was uneventful and there was no complication. Results were evaluated clinically and comments of peers. Most of the patient of congenital muscular torticollis can be treated conservatively during infancy. Division of both sternal and clavicular head of SCM is easy and safe surgical technique for the treatment of CMT of older children and adolescents.

    Congenital heart block (CHB) is the main complication of neonatal lupus (NL) and is strongly associated with the presence of anti-SSA/Ro and anti-SSB/La antibodies. The recurrence of CHB in subsequent pregnancies in mothers with these antibodies is uncommon, occurring in approximately 15% of cases. We describe here a case of recurrent CHB in a previously asymptomatic mother with Sjögren syndrome and discuss the current strategies for the prevention and treatment of CHB in NL.

    Three patients who had a diagnosis of congenitally absent lumbar pedicle underwent CT examination. Findings showed that each patient had an aberrant hypoplastic pedicle plus a retroisthmic defect in their ipsilateral lamina rather than an absent pedicle. Axial CT was the diagnostic modality of choice; reformated images were of little value. The differential diagnosis to be considered from the findings of plain film radiography includes pediculate thinning, neoplastic disease, neurofibroma, mesodermal dysplasia associated with neurofibromatosis, and vascular anomalies.

    To estimate the prevalence of congenital toxoplasmosis, Chagas disease, cytomegalovirus, and rubella, blood samples on dried blood spot (DBS) from neonates (day 3-20 of life) were screened for immunoglobulin (Ig) M against Toxoplasma gondii, cytomegalovirus, rubella virus, and IgG against Trypanosoma cruzi by methods used for serum and adapted for use with DBS. Positive samples were further analyzed for IgM and IgG in serum from neonates and mothers. DBS samples from 364,130 neonates were tested for Toxoplasma gondii-specific IgM, and 15,873 neonates were also tested for IgM against cytomegalovirus and rubella virus and for Trypanosoma cruzi-specific IgG. A total of 195 were diagnosed with congenital toxoplasmosis, 16 with cytomegalovirus, and 11 with congenital rubella. One newborn had a confirmed result for Chagas disease, and 21 mothers had positive serum antibodies. These results suggest that infectious diseases should be considered for future inclusion in programs for newborn screening of metabolic diseases in disease-endemic areas. PMID:15207059

  3. Reduced taste sensitivity in congenital blindness.

    2013-07-01

    Sight is undoubtedly not only important for food identification and selection but also for the modulation of gustatory sensitivity. We can, therefore, assume that taste sensitivity and eating habits are affected by visual deprivation from birth. We measured taste detection and identification thresholds of the 5 basic tastants in 13 congenitally blind and 13 sighted control subjects. Participants also answered several eating habits questionnaires, including the Food Neophobia Scale, the Food Variety Seeking Tendency Scale, the Intuitive Eating Scale, and the Body Awareness Questionnaire. Our behavioral results showed that compared with the normal sighted, blind subjects have increased thresholds for taste detection and taste identification. This finding is at odds with the superior performance of congenitally blind subjects in several tactile, auditory and olfactory tasks. Our psychometric data further indicate that blind subjects more strongly rely on internal hunger and satiety cues, instead of external contextual or emotional cues, to decide when and what to eat. We suggest that the lower taste sensitivity observed in congenitally blind individuals is due to various blindness-related obstacles when shopping for food, cooking and eating out, all of which contribute to underexpose the gustatory system to a larger variety of taste stimuli.

    Ocular and adnexal congenital disorders are those that manifest at birth and could involve single or multiple tissues. Several abnormalities have been reported in literature affecting reptilian ocular and/or adnexal tissues. The objectives of this review are: (i) review those disorders previously reported in reptile literature; (ii) present new cases; (iii) provide a basic classification of them according to the moment of occurrence and (iv) indirectly, encourage the clinician dealing with these cases to go further in their diagnosis. The authors consider that categorizing ocular and adnexal congenital disorders could help the clinician to deal with them. The categorization of these disorders required an intense review of cases previously reported in literature and allows the authors suspect that some of them could not have been accurately diagnosed according to the definitions of the anomalies and/or not accurately described. The authors consider that ocular and adnexal congenital disorders could have been underestimated in reptiles and further studies could be helpful to promote the description of new disorders and to expand the knowledge about those previously reported. The review will first describe abnormalities reported during organogenesis (describing possible etiopathogenesis, cases reported, an approach to their diagnosis and recommended therapeutic options).Then a mention of the ocular disorders occurring after organogenesis is made. These disorders are divided when possible in those affecting all or most part of the globe and those affecting only specific tissues (surface ectoderm, neurocrest and mesenchyma and neuroectoderm).

    Purpose To report the results of late nasolacrimal duct probing in patients with congenital nasolacrimal duct obstruction (NLDO). Methods This retrospective study was performed on a consecutive series of patients with congenital NLDO who underwent late (after 15 months of age) nasolacrimal duct probing for the first time. Results Over a period of five years, 158 patients including 75 (47.4%) male and 83 (52.6%) female subjects with mean age of 3±4.2 years (range, 15 months to 37 years) underwent initial probing for NLDO. Nasolacrimal duct probing was performed unilaterally in 78% and bilaterally in 22% of the patients. Success rate was 75% overall, 72% in unilateral cases and 83% in bilateral instances. Success rate was not correlated with age at intervention. Conclusion Nasolacrimal duct probing seems to be reasonably successful for treatment of congenital NLDO in patients older than 15 months who are seen for the first time. Silicone intubation or dacryocystorhinostomy should be reserved for refractory cases. PMID:23198056

    Abate, Michele; Salini, Vincenzo; Andia, Isabel

    2016-01-01

    Congenital metabolic disorders are consequence of defects involving single genes that code for enzymes. Blocking metabolic pathways, the defect leads to the shortage of essential compounds, and/or to the accumulation of huge quantities of precursors, which interfere with normal functions. Only few of these diseases are characterized by a clinically significant tendon involvement.Heterozygous Familial Hypercholesterolaemia results from the inheritance of a mutant low-density lipoprotein receptor gene; patients show high cholesterol levels, precocious coronary artery disease, and may develop tendon xanthomata (mainly in Achilles tendon). The detection of xanthomata is important, because it allows an early diagnosis and treatment of the disorder. Cerebrotendinous Xanthomatosis is a rare genetic metabolic disorder of cholesterol and bile acid metabolism, characterized by accumulation of cholestanol in brain and tendons. Tendon abnormalities are similar to those reported in Heterozygous Familial Hypercholesterolaemia. Alkaptonuria is caused by a deficiency of the enzyme homogentisic acid oxidase. Due to the accumulation of the homogentisic acid, tendons and ligaments are characterized by a typical ochre/yellow pigmentation (ochronosis), with ensuing inflammation, calcification and rupture. In Congenital Hypergalactosemia an increased tendon collagen cross-linking by non-enzymatic galactosylation can be observed. Finally, Congenital Hypophosphatasia may be associated to deposition of hydroxyapatite crystals in rotator cuff, elbow, and Achilles tendons. PMID:27535253

    Background The purpose of this study was to report outcomes of congenital hallux varus deformity after surgical treatment. Methods We evaluated ten feet of eight patients with a congenital hallux varus deformity, including four feet combined with a longitudinal epiphyseal bracket (LEB). There were seven male patients and one female patient with a mean age of 33 months (range, 7 to 103 months) at the time of surgery. Two patients were bilaterally involved. The mean duration of follow-up was 5.9 years (range, 2.3 to 13.8 years). Clinical outcomes were assessed according to the criteria of Phelps and Grogan. Surgical procedures included the Farmer procedure, the McElvenny procedure or an osteotomy at the first metatarsal or proximal phalanx. Results The clinical results were excellent in two feet, good in six and poor in two feet. The LEB was associated with hallux varus in four feet and were treated by osteotomy alone or in conjunction with soft tissue procedure. Conclusions Congenital hallux varus was successfully corrected by surgery with overall favorable outcome. Preoperatively, a LEB should be considered as a possible cause of the deformity in order to prevent recurrent or residual varus after surgery. PMID:24900905

    2001-06-01

    Congenital disorders of glycosylation, formerly called carbohydrate-deficient glycoprotein syndrome, may present in infancy with slowly progressive neurologic deficits including cognitive impairment, ataxia, pigmentary retinal degeneration, and neuropathy. The metabolic defect is in N-linked oligosaccharide synthesis, and diagnosis is made by a serum transferrin isoelectric focusing. We reviewed the neurologic course of 10 children with congenital disorders of glycosylation (ages 13 months to 7 years). All had severe developmental delay and ataxia; none walked unassisted, and the highest level of communication was simple sign language in one patient. Five of 10 children had seizures (absence, complex partial, tonic clonic). Only one patient has had strokelike episodes, despite reports that they are common in this population. The underlying basis of these episodes has been hypothesized to be coagulopathy due to dysfunctional, incorrectly glycosylated coagulation factors. This 5-year-old patient with congenital disorders of glycosylation type Ia had two strokelike episodes, with evolving hemiparesis over 5 to 6 days' duration, followed by focal tonic-clonic seizures. Coagulation studies were normal. Electroencephalography showed transient hemispheric polymorphous delta-range slowing and suppression. Magnetic resonance imaging revealed corresponding cortical swelling. Magnetic resonance angiography was normal. Magnetic resonance spectroscopy revealed a decrease in the N-acetylaspartate peak, suggesting neuronal loss, with normal lactate peak. The neuroradiologic data do not support a thrombotic, embolic, or hemorrhagic basis for strokelike episodes in carbohydrate-deficient glycoprotein syndrome; other mechanisms must be considered.

  9. Congenital urinary tract obstruction: the long view.

    PubMed

    Chevalier, Robert L

    2015-07-01

    Maldevelopment of the collecting system resulting in urinary tract obstruction (UTO) is the leading identifiable cause of CKD in children. Specific etiologies are unknown; most cases are suspected by discovering hydronephrosis on prenatal ultrasonography. Congenital UTO can reduce nephron number and cause bladder dysfunction, which contribute to ongoing injury. Severe UTO can impair kidney growth in utero, and animal models of unilateral ureteral obstruction show that ischemia and oxidative stress cause proximal tubular cell death, with later development of interstitial fibrosis. Congenital obstructive nephropathy, therefore, results from combined developmental and obstructive kidney injury. Because of inadequacy of available biomarkers, criteria for surgical correction of upper tract obstruction are poorly established. Lower tract obstruction requires fetal or immediate postnatal intervention, and the rate of progression of CKD is highly variable. New biomarkers based on proteomics and determination of glomerular number by magnetic resonance imaging should improve future care. Angiotensin inhibitors have not been effective in slowing progression, although avoidance of nephrotoxins and timely treatment of hypertension are important. Because congenital UTO begins in fetal life, smooth transfer of care from perinatologist to pediatric and adult urology and nephrology teams should optimize quality of life and ultimate outcomes for these patients.

    Congenital anomaly of the oval window with an abnormal facial nerve course is an uncommon embryological defect, which is related to the underdevelopment of second branchial arch derivatives. Some treatments for improving hearing levels are available; these include hearing aids, vestibulotomy, neo-oval window formation, and stapes surgeries, including incudostapedotomy and malleostapedotomy. However, surgery for congenital anomalies of the oval window has rarely been described, usually in very small series of patients. We describe two cases of congenital anomalies of the oval window with aberrant facial nerve courses. One was a 40-year-old male diagnosed with unilateral congenital oval window atresia; the other was a 10-year-old male diagnosed with bilateral congenital oval window atresia. We also describe the clinical manifestations and treatment outcomes of malleostapedotomy for congenital anomalies of the oval window with aberrant facial nerve courses. PMID:24653925

    2015-01-01

    Congenital cholesteatomas are epithelial lesions that present as an epithelial pearl behind an intact eardrum. Congenital and acquired cholesteatomas progress quite differently from each other and progress patterns can provide clues about the unique origin and pathogenesis of the abnormality. However, the exact pathogenic mechanisms by which cholesteatomas develop remain unknown. In this study, key proteins that directly affect cholesteatoma pathogenesis are investigated with proteomics and immunohistochemistry. Congenital cholesteatoma matrices and retroauricular skin were harvested during surgery in 4 patients diagnosed with a congenital cholesteatoma. Tissue was also harvested from the retraction pocket in an additional 2 patients during middle ear surgery. We performed 2-dimensional (2D) electrophoresis to detect and analyze spots that are expressed only in congenital cholesteatoma and matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF/MS) to separate proteins by molecular weight. Protein expression was confirmed by immunohistochemical staining. The image analysis of 2D electrophoresis showed that 4 congenital cholesteatoma samples had very similar protein expression patterns and that 127 spots were exclusively expressed in congenital cholesteatomas. Of these 127 spots, 10 major spots revealed the presence of titin, forkhead transcription activator homolog (FKH 5–3), plectin 1, keratin 10, and leucine zipper protein 5 by MALDI-TOF/MS analysis. Immunohistochemical staining showed that FKH 5–3 and titin were expressed in congenital cholesteatoma matrices, but not in acquired cholesteatomas. Our study shows that protein expression patterns are completely different in congenital cholesteatomas, acquired cholesteatomas, and skin. Moreover, non-epithelial proteins, including FKH 5–3 and titin, were unexpectedly expressed in congenital cholesteatoma tissue. Our data indicates that congenital cholesteatoma origins may differ

    We carried out a device-needs survey to evaluate the gaps in device and equipment availability for congenital interventional cardiologists. As the complexity and demand for more complete solutions to congenital heart lesions increase, there is a growing need for modification and development of devices and equipment to support this endeavor. The survey was sent out via e-mail to members of the Congenital Cardiovascular Interventional Study Consortium and the Society for Cardiac Angiography and Interventions with a reach of over 350 congenital interventionalists. Responses were received from 68 cardiologists in 8 countries. In terms of the most desired device, 41 % ranked bioresorbable stents as their first choice from a list of 12 possible devices. Similarly, 23 % ranked large covered stents as their first choice. Twenty-seven percent of participants believed bioresorbable stents would have the greatest potential to improve morbidity of their patients, with another 27 % reporting that covered stents would have the greatest impact. Fifty percent of participants reported that they would like to see large covered stents available in their country. These data point toward a perceived need for the development/approval of bioresorbable stents for the pediatric age group, as well as the need to approve the use of large covered stents in the pediatric age group in the USA.

    There is substantial evidence that congenitally blind individuals perform better than normally sighted controls in a variety of auditory, tactile and olfactory discrimination tasks. However, little is known about the capacity of blind individuals to make fine discriminatory judgments in the thermal domain. We therefore compared the capacity to detect small temperature increases in innocuous heat in a group of 12 congenitally blind and 12 age and sex-matched normally sighted participants. In addition, we also tested for group differences in the effects of spatial summation on temperature discrimination. Thermal stimuli were delivered with either a 2.56 or 9 cm(2) Peltier-based thermode. We applied for 5-8s lasting non-painful thermal stimuli to the forearm and asked participants to detect small increments in temperature (ΔT = 0.4, 0.8, 1.2 or 1.6°C) that occurred at random time intervals. Blank trials (ΔT = 0°C) were also included to test for false positive responses. We used signal detection theory model to analyze the data. Our data revealed that blind participants have a higher accuracy than the sighted (d': Blind=2.4 ± 1.0, Sighted=1.8 ± 0.7, p=0.025), regardless of the size of the stimulated skin surface or magnitude of the temperature shift. Increasing the size of the stimulated skin area increased the response criterion in the blind (p=0.022) but not in the sighted. Together, these findings show that congenitally blind individuals have enhanced temperature discrimination accuracy and are more susceptible to spatial summation of heat. PMID:25639543

    Congenital adrenal hyperplasia (CAH) is a group of autosomal recessive disorders characterized by enzyme defects in adrenal steroidogenic pathways. CAH due to 21-hydroxylase deficiency accounts for 95 % of cases. This case was diagnosed to have simple virilizing type of CAH and started on dexamethasone, and underwent genitoplasty and clitoroplasty at 25 years of age, then was married 3 years after surgery and conceived spontaneously 2 years after marriage, to deliver a healthy male baby. Thus, proper diagnosis and treatment with steroids and genitoplasty can give females with CAH a normal sexual, normal menstrual, and reproductive function.

    2015-01-01

    Synopsis Adrenal steroidogenesis is a dynamic process, reliant on de novo synthesis from cholesterol, under the stimulation of ACTH and other regulators. The syntheses of mineralocorticoids, glucocorticoids and adrenal androgens occur in separate adrenal cortical zones, each expressing specific enzymes. Congenital adrenal hyperplasia (CAH) encompasses a group of autosomal recessive enzymatic defects in cortisol biosynthesis. 21-hydroxylase (21OHD) deficiency accounts for over 90% of CAH cases and when milder or nonclassic forms are included, 21OHD is one of the most common genetic diseases. This review discusses in detail the epidemiology, genetics, diagnostic, clinical aspects and management of 21OHD. PMID:26038201

    PubMed

    Gosselin, Nathalie; Jolicoeur, Pierre; Peretz, Isabelle

    2009-07-01

    We examined memory for pitch in congenital amusia in two tasks. In one task, we varied the pitch distance between the target and comparison tone from 4 to 9 semitones and inserted either a silence or 6 interpolated tones between the tones to be compared. In a second task, we manipulated the number of pitches to be retained in sequences of length 1, 3, or 5. Amusics' sensitivity to pitch distance was exacerbated by the presence of interpolated tones, and amusics' performance was more strongly affected by the number of pitches to maintain in memory than controls. A pitch perception deficit could not account for the pitch memory deficit of amusics. PMID:19673791

    Congenital melanocytic naevi (CMN) appear in approximately 2.6% of Caucasians. There is a major demand for treatment but no vital indication. Laser therapy, curettage and excision are available treatment modalities, but there is no ideal treatment with documented long-term effect and without side effects, and the level of evidence for the treatment options is generally low. The risk of malignancy has probably been overestimated, and furthermore new research shows that untreated CMN often show spontaneous lightening. We review the literature for pros and cons of different treatments. PMID:27649711

    At present there is no universally accepted nomenclature for congenital cardiac malformations. Much of the controversy results from failure to distinguish the structural connections of the heart from the morphology and spatial relations of its components. The confusion is compounded by an abundance of individual definitions, many of them speculative. The present article proposes a totally descriptive nomenclature. It describes in turn the connections of the cardiac segments, their morphology, their relations, and additional anomalies in any segment. Each step in the segmental approach is discrete. The overall effect is to force a succinct and comprehensive description of any cardiac malformation, no matter how complex. Images PMID:465224

    Congenital diaphragmatic hernia (CDH) is a common major malformation affecting 1/3000–1/4000 births, which continues to be associated with significant perinatal mortality. Much current research is focused on elucidating the genetics and pathophysiology contributing to CDH to develop more effective therapies. The latest data suggest that many cases of CDH are genetically determined and also indicate that CDH is etiologically heterogeneous. The present review will provide a brief summary of diaphragm development and model organism work most relevant to human CDH and will primarily describe important human phenotypes associated with CDH and also provide recommendations for diagnostic evaluation of a fetus or infant with CDH.

    This article presents a case of multidrug-resistant tuberculosis (TB) in a Peruvian infant. His mother was diagnosed with disseminated TB, and treatment commenced 11 days postpartum. The infant was diagnosed with TB after 40 days and died at 2 months and 2 days of age. Congenital transmission of TB to the infant was suspected, because direct postpartum transmission was considered unlikely; also, thorough screening of contacts for TB was negative. Spoligotyping confirmed that both mother and baby were infected with identical strains of the Beijing family (SIT1). PMID:24821847

    Congenital laryngeal cysts are a rare cause of stridor in the neonate. Nevertheless, delayed diagnosis and treatment can cause life-threatening airway obstruction. Even though the diagnosis is easily made by careful inspection, treatment results often in recurrence. These facts are illustrated by a case of a baby with a saccular cyst. Immediately after diagnosis and 5 days later the cyst was de-roofed using a CO2 laser via an endolaryngeal approach. Because of a second recurrence an excision of the cyst was performed via a lateral cervical approach. PMID:12836468

    Bronchopulmonary foregut malformations are a heterogeneous but interrelated group of abnormalities that may contain more than one histologic feature. It is helpful to be familiar with the presentation and imaging features of bronchopulmonary foregut malformations presenting as a congenital mass or mass-like lesion, as imaging plays a central role in the evaluation of these lesions since, when symptomatic, clinical features are usually nonspecific. With imaging, the presence of other associated lesions can be determined, facilitating appropriate management to prevent the potential complications. We report a case of coexisting extralobar pulmonary sequestration and ipsilateral diaphragmatic hernia in a term neonate. PMID:27445516

    Congenital adrenal hyperplasia (CAH) owing to 21-hydroxylase deficiency is a monogenic disorder of adrenal steroidogenesis. To prevent genital ambiguity, in girls, prenatal dexamethasone treatment is administered early in the first trimester. Prenatal genetic diagnosis of CAH and fetal sex determination identify affected female fetuses at risk for genital virilization. Advancements in prenatal diagnosis are owing to improved understanding of the genetic basis of CAH and improved technology. Cloning of the CYP21A2 gene ushered in molecular genetic analysis as the current standard of care. Noninvasive prenatal diagnosis allows for targeted treatment and avoids unnecessary treatment of males and unaffected females. PMID:27241964

This is the first description of comprehensive neuropsychological assessment in a child with this syndrome. The results reflect significant impairments in auditory processing and independent learning and retention, but relatively preserved cognitive performance on interactive tasks involving frequent feedback and redirection.

The symptoms present at birth included severe general muscular hypotonia, diffuse muscular atrophy, arthrogryposis, absence of spontaneous movements, and left ventricular hypertrophy. A biopsy specimen taken from the gastrocnemius muscle when the patient was 2 weeks old revealed deposits which consisted of actin filaments as shown by electron microscopy. The infant was occasionally respirator dependent but was mostly able to breathe unassisted. At the age of 5 months he died of respiratory failure. The actin filament deposits may explain the clinical findings.

    Congenital urethral duplication is a rare anomaly, with less than 200 cases described in the literature. The investigations that are usually performed are micturating cystourethrography (MCU) and retrograde urethrography (RGU), which can diagnose the presence of duplication but cannot diagnose the precise relationship of the duplicated urethra with other pelvic structures. MRI, because of the excellent tissue contrast that it provides and its multiplanar ability, can demonstrate with precision, the size, shape and position of the two urethras. We describe below a case where MRI was able to show this exquisitely. PMID:19881093

    Congenital absence of the vagina is a relatively rare condition most commonly associated with Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome. Historically, several reconstructive techniques have been described to provide for functional vaginal reconstruction on these patients, both operative and nonoperative. Although there are many advantages and disadvantages of the various procedures, one experience with the use of split thickness skin grafts to reconstruct the vagina has produced acceptable functional results with limited donor site morbidity. Careful planning and timing of this form of reconstruction can produce predictable results in patients who are nearing sexual maturity. PMID:22547971

    Study Design Retrospective study. Purpose To identify the incidence of congenital cardiac abnormalities in patients who had scoliosis and underwent surgical treatment for scoliosis. Overview of Literature Congenital and idiopathic scoliosis (IS) are associated with cardiac abnormalities. We sought to establish and compare the incidence of congenital cardiac abnormalities in patients with idiopathic and congenital scoliosis (CS) who underwent surgical treatment for scoliosis. Methods Ninety consecutive scoliosis patients, who underwent surgical correction of scoliosis, were classified as CS (55 patients, 28 female [51%]) and IS (35 patients, 21 female [60%]). The complete data of the patients, including medical records, plain radiograph and transthoracic echocardiography were retrospectively assessed. Results We found that mitral valve prolapse was the most common cardiac abnormality in both patients with IS (nine patients, 26%) and CS (13 patients, 24%). Other congenital cardiac abnormalities were atrial septal aneurysm (23% of IS patients, 18% of CS patients), pulmonary insufficiency (20% of IS patients, 4% of CS patients), aortic insufficiency (17% of IS patients), atrial septal defect (11% of IS patients, 13% of CS patients), patent foramen ovale (15% of CS patients), dextrocardia (4% of CS patients), bicuspid aortic valve (3% of IS patients), aortic stenosis (2% of CS patients), ventricular septal defect (2% of CS patients), and cardiomyopathy (2% of CS patients). Conclusions We determined the increased incidence of congenital cardiac abnormalities among patients with congenital and IS. Mitral valve prolapse appeared to be the most prevalent congenital cardiac abnormality in both groups. PMID:27114761

    Congenital uterine anomalies in women often do not cause any symptoms, except when there is an obstruction of the uterine outflow tract, which occurs infrequently. Patients with congenital uterine anomalies often go undetected or are only discovered incidentally during an evaluation for something else. Consequently, it is difficult to determine the prevalence of congenital uterine anomalies in the general population, and it appears more frequently in certain populations, namely in those with recurrent pregnancy loss or infertility. This paper will review the pathogenesis of congenital uterine anomalies and the standard classification for these anomalies. We will focus on ultrasound and other diagnostic modalities (hysterosalpingogram, laparoscopy with hysteroscopy, and magnetic resonance imaging). We will compare the accuracy and differences between these diagnostic techniques. With the development of three-dimensional ultrasound, the diagnosis of congenital uterine anomalies can be made accurately, effectively, and with less invasiveness than with other procedures. We will briefly review the treatments and pregnancy outcomes in these different anomalies.

    Congenital cholesteatoma arises behind a normal, intact tympanic membrane and is most plausibly explained by the persistence of fetal epidermoid formation. It is generally accepted that cholesteatoma in children has greater aggressive growth activity than that in adults. The congenital type of cholesteatoma starts as a small pearl in the middle ear and eventually grows to involve the ossicles and then the attic and mastoid, causing varying degrees of destruction and functional impairment. However, here we report the cases of two children with congenital cholesteatoma which disappeared spontaneously during the follow-up period. To the best of our knowledge, this is the first report on the spontaneous regression of congenital cholesteatoma. On the basis of the two cases, we could take a "wait and watch" attitude for congenital cholesteatoma in the absence of severe infection, hearing loss, or bone destruction in the middle ear.

    Over a 17-month period we prospectively recorded identifiable congenital malformations at delivery in singleton births in our hospital. Despite the prevailing religious and cultural belief we carried out autopsies in 41% of the perinatal deaths that occurred during the study period. Out of a total of 63 (21/1000 singleton births) congenital malformations discovered, 21 (33%) were identified at autopsy only. About 16% of total perinatal deaths were due to congenital malformation. Cardiovascular malformations accounted for about 40% of perinatal deaths from congenital malformations followed by central nervous system malformation (23.3%), gastrointestinal malformations (20%), musculo-skeletal malformations (6.7%); renal malformations (3.3%) and others (6.7%). No relationship between maternal age, parity and congenital malformation was found. The results from this study suggest that with the use of autopsy, teratology may contribute significantly to the prevailing high perinatal mortality in Lagos more than was previously thought.

    2011-12-01

    In this issue of Seminars in Pediatric Neurology, each chapter will focus on the features and management of individual congenital myopathies. This introductory chapter will provide an overview of the clinical features that alert the clinician to the likely diagnosis of a congenital myopathy, and specific features on history and examination that are characteristic of a specific genetic subtype. Most congenital myopathies share a common pattern of clinical features, which makes it difficult to predict the genetic cause in a patient by clinical assessment alone. Although no single feature is specific for the congenital myopathies, the presence of this common pattern highlights patients in whom a muscle biopsy is likely to provide important diagnostic information. The diagnosis of a specific congenital myopathy should only be made when the defining morphologic feature is the predominant pathologic change, other possible causes have been excluded, and the clinical course is nonprogressive or only slowly progressive.

    The congenital heart disease includes abnormalities in heart structure that occur before birth. Such defects occur in the fetus while it is developing in the uterus during pregnancy. About 500,000 adults have congenital heart disease in USA (WebMD, Congenital heart defects medications, www.WebMD.com/heart-disease/tc/congenital-heart-defects-medications , 2014). 1 in every 100 children has defects in their heart due to genetic or chromosomal abnormalities, such as Down syndrome. The excessive alcohol consumption during pregnancy and use of medications, maternal viral infection, such as Rubella virus, measles (German), in the first trimester of pregnancy, all these are risk factors for congenital heart disease in children, and the risk increases if parent or sibling has a congenital heart defect. These are heart valves defects, atrial and ventricular septa defects, stenosis, the heart muscle abnormalities, and a hole inside wall of the heart which causes defect in blood circulation, heart failure, and eventual death. There are no particular symptoms of congenital heart disease, but shortness of breath and limited ability to do exercise, fatigue, abnormal sound of heart as heart murmur, which is diagnosed by a physician while listening to the heart beats. The echocardiogram or transesophageal echocardiogram, electrocardiogram, chest X-ray, cardiac catheterization, and MRI methods are used to detect congenital heart disease. Several medications are given depending on the severity of this disease, and catheter method and surgery are required for serious cases to repair heart valves or heart transplantation as in endocarditis. For genetic study, first DNA is extracted from blood followed by DNA sequence analysis and any defect in nucleotide sequence of DNA is determined. For congenital heart disease, genes in chromosome 1 show some defects in nucleotide sequence. In this review the causes, diagnosis, symptoms, and treatments of congenital heart disease are described

    Congenital anophthalmia and blind microphthalmia are very rare conditions and there is no standard treatment available. Various previously reported therapeutical concepts are reviewed. The clinical picture can be divided into three subgroups with different therapeutical options recommended: in microphthalmia the conjunctival sac size is usually normal or slightly decreased. The use of non-expandable conformers is possible with good results. Patients treated with hydrogel expanders can wear a prosthesis earlier and with better cosmetic results. In congenital anophthalmia the conjunctival sac is very small and contracted and patients cannot wear a prosthesis or even a conformer. Hydrogel expander treatment--first for the conjunctival sac and second for the orbit--is the therapeutical option which may lead to good cosmetic results. Children >5 years of age and/or unsuccessful pre-treated cases may benefit from osteotomy to reduce mid-face asymmetry. To attain the main therapeutical goal in this subgroup, the ability to fit a normal prosthesis, a combination of different techniques like hydrogel expanders, dermis fat graft, lid surgery etc. may be necessary.

  9. Pregnancy in women with congenital heart disease

    Due to advances in paediatric congenital heart surgery, there are a growing number of women with congenital heart disease (CHD) reaching childbearing age. Pregnancy, however, is associated with haemodynamic stresses which can result in cardiac decompensation in women with CHD. Many women with CHD are aware of their cardiac condition prior to pregnancy, and preconception counselling is an important aspect of their care. Preconception counselling allows women to make informed pregnancy decisions, provides an opportunity for modifications of teratogenic medications and, when necessary, repair of cardiac lesions prior to pregnancy. Less commonly, the haemodynamic changes of pregnancy unmask a previously unrecognised heart lesion. In general, pregnancy outcomes are favourable for women with CHD, but there are some cardiac lesions that carry high risk for both the mother and the baby, and this group of women require care by an experienced multidisciplinary team. This review discusses preconception counselling including contraception, an approach to risk stratification and management recommendations in women with some common CHDs. PMID:27512454

    In a series of chronic renal and congenitally deaf patients 24 were identified as having inborn renal and otologic disease. Sixteen patients, representing 14 families, had genetic disorders. Only two had the features of Alport's syndrome. The patients were classified as follows: 1) Probable Alport's--2 patients (1 family); 2) Atypical hereditary nephritis and sensorineural hearing loss--7 patients; 3) Renal and inner ear anomalies--1 patient; 4) Renal, inner ear and multiple anomalies--4 patients. The temporal bone pathology in one case showed primary neural atrophy and a mild Mondini malformation. In another a Scheibe defect and unusual calcific structures were found in the cochlear duct. 5) Renal, external or middle ear and multiple anomalies--6 patients (5 families); 6 Renal, middle and inner ear anomalies and multiple anomalies--2 patients. A temporal bone obtained from one case showed combined middle and inner ear defects. In the other, who had a chromosome defect, predominantly middle ear anomalies were found. 7) Nephrotic syndrome and congenital hearing loss--1 patient; 8) Unclassified--1 patient. Some cases represent entities apparently not previously described. Probably most interesting is the delineation of hereditary nephritis and deafness distinct from Alport's disease. PMID:423658

    Congenital macrothrombocytopenia (CMTP) is a heterogeneous group of rare platelet disorders characterized by a congenital reduction of platelet counts and abnormally large platelets, for which CMTP-causing mutations are only found in approximately half the cases. We herein performed whole-exome sequencing and targeted Sanger sequencing to identify mutations that cause CMTP, in which a dominant mode of transmission had been suspected but for which no known responsible mutations have been documented. In 13 Japanese CMTP-affected pedigrees, we identified six (46%) affected by ACTN1 variants cosegregating with CMTP. In the entire cohort, ACNT1 variants accounted for 5.5% of the dominant forms of CMTP cases and represented the fourth most common cause in Japanese individuals. Individuals with ACTN1 variants presented with moderate macrothrombocytopenia with anisocytosis but were either asymptomatic or had only a modest bleeding tendency. ACTN1 encodes α-actinin-1, a member of the actin-crosslinking protein superfamily that participates in the organization of the cytoskeleton. In vitro transfection experiments in Chinese hamster ovary cells demonstrated that altered α-actinin-1 disrupted the normal actin-based cytoskeletal structure. Moreover, transduction of mouse fetal liver-derived megakaryocytes with disease-associated ACTN1 variants caused a disorganized actin-based cytoskeleton in megakaryocytes, resulting in the production of abnormally large proplatelet tips, which were reduced in number. Our findings provide an insight into the pathogenesis of CMTP.

    1995-03-01

    The relationship between levels of biliary amylase measured at operation and clinical features was studied in a series of 55 children with congenital biliary dilatation (choledochal cyst) who presented between 1976 and 1993. There were 36 cystic and 19 fusiforms dilatations in the series. The most common modes of presentation were painless jaundice (n = 23) and pancreatitis (n = 22). Five infants presented with abnormal antenatal ultrasound examinations. Children with pancreatitis were older than those with painless jaundice (4.2 versus 1.5 years; P = .005), and a higher proportion had raised levels of biliary amylase (100% versus 44%; P < .0001). There was no difference in the age at presentation (P = .32), clinical mode of presentation (P = .3), or the level of biliary amylase (P = .25) between cystic and fusiform dilatations. A correlation was found between age at surgery and biliary amylase in the cystic (rs = 0.55; P = .001) but not in the fusiform group (P = .22). All infants with antenatal diagnoses were cystic dilatations. Choledochal cystic dilatations that were diagnosed antenatally did not have significant amylase reflux, suggesting that the aetiology of this subgroup is truly congenital. Children who present at a later age with pancreatitis invariably have high levels of biliary amylase, which is presumed to occur because of a common channel and reflux of biliary and pancreatic secretions.

    1981-01-01

    Congenital fistulas are the most common of the coronary arterial malformations and with the widespread use of selective coronary arteriography are being recognized with increasing frequency. Twenty-eight patients with congenital coronary fistulas have been evaluated at the Duke University Medical Center between 1960 and 1981. An additional 258 patients have previously been reported in the literature, making a total of 286 available for review. The right coronary artery is most commonly involved, and the fistulous communication is most often to the right ventricle, right atrium or pulmonary artery. Slightly more than half of the patients with coronary fistulas are symptomatic at the time the diagnosis is made. Surgical correction is strongly recommended to prevent the development of congestive heart failure, angina, subacute bacterial endocarditis, myocardial infarction, and pulmonary hypertension, as well as coronary aneurysm formation, with subsequent rupture or embolization. There were no operative or late deaths in the patients who underwent operations. Moreover, there have been no recurrent fistulas during a mean follow-up period of ten years. The risks of operative correction appear to be considerably less than the potential for development of serious and potentially fatal complications, even in asymptomatic patients. Images Fig. 2a.

    2015-07-01

    Three types of congenital diaphragmatic hernias( Bochdalek hernia, Morgagni hernia, and esophageal hiatus hernia) are described with case presentation. In the Bochdalek hernia, the most common type of congenital diaphragmatic hernia, abdominal contents pass into the thorac bia diaphragmatic defect, limiting the space available for the developing lungs. Resulting lung hypoplasia, many infants experience severe respiratory distress within minutes of birth and may require resuscitation and stabilization of cardio-pulmonary function prior to surgery. The Morgagni hernia is rare and often incidentally diagnosed on routine chest x-ray in asymptomatic patients. Repair is still advisable due to risk of strangulated bowel and respiratory distress. Esophageal hiatal hernias usually produce symptoms of gastroesophageal reflux( GERD) and rarely result in incarceration of stomach or other organs. Surgical interventions for GERD, such as Nissen fundoplication, usually target neurologically impaired children in order to prevent aspiration pneumonia and improve quality of life. Laparoscopic surgery is beneficial for all types of diaphragmatic hernia, especially in older children, but careful consideration should be made based on individual patient background. PMID:26197915

    2014-01-01

    Cardiovascular malformations are a singularly important class of birth defects and, due to dramatic improvements in medical and surgical care, there are now large numbers of adult survivors. The etiologies are complex, but there is strong evidence that genetic factors play a crucial role. Over the last 15 years there has been enormous progress in the discovery of causative genes for syndromic heart malformations and in rare families with Mendelian forms. The rapid characterization of genomic disorders as major contributors to congenital heart defects is also notable. The genes identified encode many transcription factors, chromatin regulators, growth factors and signal transduction pathways– all unified by their required roles in normal cardiac development. Genome-wide sequencing of the coding regions promises to elucidate genetic causation in several disorders affecting cardiac development. Such comprehensive studies evaluating both common and rare variants would be essential in characterizing gene-gene interactions, as well as in understanding the gene-environment interactions that increase the susceptibility to congenital heart defects.

    Vision is important for avoiding encounters with objects in the environment that may imperil physical integrity. We tested whether, in the absence of vision, a lower pain threshold would arise from an adaptive shift to other sensory channels. We therefore measured heat and cold pain thresholds and responses to suprathreshold heat stimuli in 2 groups of congenitally blind and matched normal-sighted participants. We also assessed detection thresholds for innocuous warmth and cold, and participants' attitude toward painful encounters in daily life. Our results show that, compared to sighted subjects, congenitally blind subjects have lower heat pain thresholds, rate suprathreshold heat pain stimuli as more painful, and have increased sensitivity for cold pain stimuli. Thresholds for nonpainful thermal stimulation did not differ between groups. The results of the pain questionnaires further indicated that blind subjects are more attentive to signals of external threats. These findings indicate that the absence of vision from birth induces a hypersensitivity to painful stimuli, lending new support to a model of sensory integration of vision and pain processing.

    During pregnancy there are hemostatic changes that result in a hypercoagulable state and can have thrombotic consequences. This condition can be aggravated in women who are carriers of congenital thrombophilic factors. This thrombotic tendency can manifest as thrombotic lesions in the placenta with compromise of utero-placental circulation, which are common characteristics present in obstetric complications, such as preeclampsia/eclampsia, miscarriage, fetal loss, intrauterine growth retardation, and abruptio placentae. In this paper we review data concerning about the association of congenital thrombophilia in pregnancy with obstetric complications, mainly preeclampsia and fetal loss, focusing in factor V Leiden and its related activated protein C resistance, prothrombin mutation G20210A and hyperhomocysteinemia related with C677T mutation of methylenetetrahydrofolate reductase. Although factor V Leiden has been the thrombophilic factor most studied, all three thrombophilic mutations have been related with obstetric complications; however, contradictory results about the specific association of each mutation with each type of obstetric complication are described. These discrepancies could obey to the ethnic difference of the studied groups, or to the fact that some studies were performed in closed populations with few migratory movement, where the genetic pool is relatively homogeneous, as well as the different inclusion and exclusion criteria. Even though this variability is present, the significance of recognizing true associations between these thrombophilic mutations and obstetric complications is essential in order to determine the likelihood of routinely screening for these conditions in pregnant women with risk factors for thrombosis and for carrying out specific prophylactic measures.

    Congenital heart defects (CHDs) are the most common of all birth defects, yet molecular mechanism(s) underlying highly prevalent atrial septal defects (ASDs) and ventricular septal defects (VSDs) have remained elusive. We demonstrate the indispensability of “balanced” post-translational SUMO conjugation-deconjugation pathway for normal cardiac development. Both hetero- and homo-zygous SUMO-1 knockout mice exhibited ASDs and VSDs with high mortality rates, which were rescued by cardiac re-expression of the SUMO-1 transgene. Since SUMO-1 was also involved in cleft lip/palate in human patients, the above findings provided a powerful rationale to question whether SUMO-1 was mutated in babies born with cleft palates and ASDs. Sequence analysis of DNA from newborn screening blood spots revealed a single 16 bp substitution in the SUMO-1 regulatory promoter of a patient displaying both oral-facial clefts and ASDs. Diminished sumoylation activity whether by genetics, environmental toxins and/or pharmaceuticals may significantly contribute to susceptibility to the induction of congenital heart disease worldwide.

    Background Congenital germ cell tumors are uncommon. The most common site of teratoma is in the sacrococcygeal region. Teratoma arising from the head and neck comprises less than 10% of reported cases and of these, nasopharyngeal lesions are rare. Teratomas are generally benign, and have a well recognized clinical and histopathological entity. We present a case of nasopharyngeal teratoma (NPT) associated with a wide cleft palate. Case Presentation A 20 day old female neonate with a teratoma of the nasopharyngeal area, and wide cleft palate was referred to our center. The protruded mass which measured 6×4×3cm, was of soft consistency, blocked the airway, and prevented oral feeding. Preoperative evaluation and imaging was performed and mass was excised 2 days after admission. Pathology revealed a well-differentiated mature solid teratoma (hairy polyp). The patient had no complication in the post-operative period. Cleft palate was surgically repaired when 2 years old. She is now a six year old girl with normal development. Conclusion Congenital nasopharyngeal teratomas are usually benign. Surgery is the treatment of choice, and should be undertaken on an urgent basis, especially in a patient who presents with signs and symptoms of airway obstruction. PMID:23056797

    Introduction: Congenital heart disease (CHD) is associated with multiple risk factors, consanguinity may be one such significant factor. The role of consanguinity in the etiology of CHD is supported by inbreeding studies, which demonstrate an autosomal recessive pattern of inheritance of some congenital heart defects. This study was done to find out the risk factors for CHD. Methods: A case-control study was done on pediatric patients at a tertiary care hospital, Aga Khan University Hospital, located in Karachi, Pakistan. A total of 500 patients, 250 cases and 250 controls were included in the study. Results: Amongst the 250 cases (i.e. those diagnosed with CHD), 122 patients (48.8%) were born of consanguineous marriages while in the controls (i.e. non-CHD) only 72 patients (28.9%) showed a consanguinity amongst parents. On multivariate analysis, consanguinity emerged as an independent risk factor for CHD; adjusted odds ratio 2.59 (95% C. I. 1.73 - 3.87). Other risk factors included low birth weight, maternal co-morbidities, family history of CHD and first born child. On the other hand, medications used by the mother during the index pregnancy, maternal age and gender of the child did not significantly increase the risk of developing CHD. Conclusions: Analyses of our results show that parental consanguinity, family history of CHD, maternal co-morbidities, first born child and low birth weight are independent risk factors for CHD.

    Peripheral odontoma is rare, and only two cases of congenital peripheral odontoma have been reported. Congenital oral fibroma is also rare. We describe a unique case of congenital peripheral developing odontoma accompanied by congenital teratomatous fibroma in an infant. Both tumors were difficult to detect on radiography. Two small masses were seen in the median anterior portion of the palatal mucosa of a 9-month-old boy. The masses had been present since birth and were surgically removed at age 28 months, when one of the masses had grown to a diameter of 8 mm. Histopathologic examination showed a fibrous lesion and a tooth germ-like rounded lesion composed of dental papilla, enamel organ, dentin, and cementum. Although congenital odontoma is rare, it should be considered when selecting appropriate treatment, as early radiographic detection is difficult.

    An analysis was done of available data from the Department of Statistics Malaysia, on the type of congenital abnormality contributing to death, to determine whether progress in health care over recent years was associated with any decline in mortality from congenital abnormality. A significant decline in death due to congenital abnormality was observed between 1991 and 1996. This was attributable to a decline in deaths due to congenital heart disease occurring because of improvements in cardiac surgical services for infants. In 1997 death due to congenital heart disease increased significantly. This could be attributed to improvements in the diagnosis of congenital heart disease in the neonate.

    Congenital heart disease (CHD) patients have an increased prevalence of extracardiac congenital anomalies (CAs) and risk of neurodevelopmental disabilities (NDDs). Exome sequencing of 1213 CHD parent-offspring trios identified an excess of protein-damaging de novo mutations, especially in genes highly expressed in the developing heart and brain. These mutations accounted for 20% of patients with CHD, NDD, and CA but only 2% of patients with isolated CHD. Mutations altered genes involved in morphogenesis, chromatin modification, and transcriptional regulation, including multiple mutations in RBFOX2, a regulator of mRNA splicing. Genes mutated in other cohorts examined for NDD were enriched in CHD cases, particularly those with coexisting NDD. These findings reveal shared genetic contributions to CHD, NDD, and CA and provide opportunities for improved prognostic assessment and early therapeutic intervention in CHD patients.

    Congenital heart disease in children is a type of birth defect. Previous studies have suggested that the transcription factor, TBX20, is involved in the occurrence and development of congenital heart disease in children; however, the specific regulatory mechanisms are yet to be evaluated. Hence, this study aimed to evaluate the relationship between the TBX20 polymorphism and the occurrence and development of congenital heart disease. The TBX20 gene sequence was obtained from the NCBI database and the polymorphic locus candidate was predicted. Thereafter, the specific gene primers were designed for the restriction fragment length polymorphism-polymerase chain reaction (RFLP-PCR) of DNA extracted from the blood of 80 patients with congenital heart disease and 80 controls. The results of the PCR were subjected to correlation analysis to identify the differences between the amplicons and to determine the relationship between the TBX20 gene polymorphism and congenital heart disease. One of the single nucleotide polymorphic locus was found to be rs3999950: c.774T>C (Ala265Ala). The TC genotype frequency in the patients was higher than that in the controls, similar to that for the C locus. The odds ratio of the TC genotypes was above 1, indicating that the presence of the TC genotype increases the incidence of congenital heart diseases. Thus, rs3999950 may be associated with congenital heart disease, and TBX20 may predispose children to the defect. PMID:27323105

    Consistent with the mission of the World Society for Pediatric and Congenital Heart Surgery to promote health care for children with congenital heart disease all around the world, a Mexican Association of Specialists in Congenital Heart Disease (abbreviated in Spanish as AMECC) was created in Mexico in 2008. Our efforts were coordinated with those of the National Health Secretary with the objective being implementation of a national plan for regionalization of care for patients with congenital heart disease. To improve our knowledge related to technologic and human resources for management of congenital heart disease, we developed a national survey. Finally, a national database was created for collecting all Mexican centers' information related to congenital heart disease care in order to quantify the advances related to the proposed plans. The database utilized international consensus nomenclature. The aim of this article is to show the sequence of our actions in relation to direct accomplishments and the current status of congenital heart disease care in Mexico. This article emphasizes the main aspects of these actions: regionalization project implementation, national survey results, and cardiovascular pediatric surgical database creation. Knowledge of outcomes related to successful actions would be useful for those countries that face similar challenges and may lead them to consider adoption of similar measures with the respective adjustments to their own reality.

    1989-01-01

    Five feeding trials were performed on three ranches to determine if a distinctive, recurring, congenital anomaly in beef calves was associated with feeding clover or grass silage without supplementation to pregnant cows overwinter. The anomaly, termed congenital joint laxity and dwarfism, was characterized at birth by generalized joint laxity, disproportionate dwarfism, and occasionally, superior brachygnathia. The anomaly had been documented for several consecutive years on these ranches and affected 2-46% of the calf crop. Pregnant cows were divided randomly into feeding groups, and the number of abnormal calves in each group was tabulated. Supplementation of the overwinter grass/clover silage diet with hay (2.5-4.5 kg/head/day) and rolled barley (0.75-1.5 kg/head/day) eliminated the problem. Supplementation of grain, without hay, was not as effective. Varying the proportions of grass and clover in the silage, and the age of the silage, did not alter the teratogenic potency of silage. Vitamin D3 supplementation did not reduce the risk of the condition. The definitive cause of congenital joint laxity and dwarfism was not determined. ImagesFigure 1.Figure 2. PMID:17423291

    Congenital laryngeal atresia is a rare cause of respiratory distress of the newborn. The defect may be isolated or occur in association with other congenital abnormalities, notably the presence of a tracheoesophageal fistula, esophageal atresia, encephalocele, or Congenital High Airway Obstructive Syndrome (CHAOS). We present the case of a newborn with no identified intrapartum abnormalities with respiratory distress at birth secondary to near-complete laryngeal atresia. Management included tracheostomy, repeated endoscopic incisions, and serial balloon dilatations employing the topical use of Mitomycin C. Seven year follow-up was significant for mobilization of the true vocal cords bilaterally, as well as successful decannulation.

Because of breastfeeding problems the mucinous swelling was incised and drained two days after birth. Immediately after drainage the swelling disappeared. Congenital oral swellings are rare. Most of them are mucoceles. Post-partum treatment is surgically, but spontaneous remission has been described. High incidence of recurrence should be taken into account when (micro-)marsupialization or incision as sole treatment is performed.

A classification of these malformations is presented together with the general principles of treatment, age of operating and surgical tactics. The authors give some examples of the anatomo-clinical forms, eyelid malformations such as entropion, ectropion, ptosis, levator eyelid retraction, medial canthus malposition, congenital eyelid colobomas, and congenital orbital abnormalities (Craniofacial stenosis, orbital plagiocephalies, hypertelorism, anophthalmos, microphthalmos and cryptophthalmos).

    Congenital malformations may occur during early embryogenesis in cases of genetic abnormalities or various environmental factors. Affected subjects most often have only one or 2 abnormalities; subjects rarely have several unrelated congenital defects. Here we describe a case of a stillborn New Zealand white rabbit with multiple complex congenital malformations, including synophthalmia, holoprosencephaly, gastroschisis, and a supernumerary hindlimb, among other anomalies. There was no historical exposure to teratogens or other known environmental causes. Although not confirmed, this case was most likely a rare spontaneous genetic event. PMID:24209970

    Introduction. Congenital nasopharyngeal teratomas are rare tumours that pose difficulties in diagnosis and surgical management. We report the first use of radiofrequency coblation in the management of such tumours. Case Report. A premature baby with a perinatal diagnosis of a large, obstructing nasooropharyngeal mass was referred to the ENT service for further investigations and management. The initial biopsy was suggestive of a neuroblastoma, but the tumour demonstrated rapid growth despite appropriate chemotherapy. In a novel use of radiofrequency coblation, the nasooropharyngeal mass was completely excised, with the final histopathology revealing a congenital nasopharyngeal teratoma. Conclusion. We report the first use of radiofrequency coblation to excise a congenital nasopharyngeal teratoma and discuss its advantages.

    Congenital alopecia includes a broad differential diagnosis and presents a diagnostic and therapeutic challenge for the physician. Congenital atrichia is a rare form of irreversible alopecia that is usually inherited as an autosomal recessive pattern. We report a 2-year-old male child presenting with total alopecia of scalp, eyebrows, eyelashes, and body hair since birth. The child had cardiac malposition with situs inversus of the viscera. Computed tomography of the chest and abdomen revealed median position of the heart with transposition of abdominal viscera. To our knowledge, this is the first case of congenital atrichia associated with situs inversus and mesocardia.

The radiographs of long bones and wrist showed generalized osteopenia with cupping and fraying of epiphyseal ends in the second week of life. The patient was managed with very high doses of vitamin D which led to clinico-radiological and biochemical improvement. More than being interesting for its extreme rarity, this report assumes importance as it brings forth the possibility of congenital rickets being a differential diagnosis for a newborn with respiratory distress.

    An effective live attenuated rubella vaccine was available since 1969 and congenital rubella syndrome can be prevented with appropriate vaccination. We report a baby with congenital rubella syndrome born in Klang valley to indicate that the Universal Rubella Vaccination Programme adopted by the Ministry of Health Malaysia since 2002 has yet to achieve its effect of eliminating transmission of rubella and preventing congenital rubella infection in the community. To our knowledge, the virus isolate represents the first successful isolation of rubella virus in this country and will serve as the reference strain for future comparison in molecular epidemiological tracking of rubella virus activity this country.

    Reparative procedures are not always feasible in congenitally abnormal mitral valves. Mechanical prosthesis has been accepted as the choice for valve replacement in the pediatric population. This report describes a case of congenital mitral valve disease requiring mitral valve replacement. The infant's mitral valve annulus was not amenable to placement of the smallest available mechanical prosthesis. The approach used here for annular and subvalvular enlargement facilitated implantation of a larger prosthesis for congenital mitral valve replacement. Five-year outcomes in a single patient may indicate broader applicability and avoidance of patient-prosthesis mismatch.

    Summary Childhood cataracts have become a leading cause of preventable childhood blindness in many areas of the world. Here we summarize regional focus group discussions from the 4th Annual International Congenital Cataract Symposium on the current situation, challenges, and recommendations for the management of congenital cataracts in sub-Saharan Africa, the Middle East and North Africa, South Asia, Central America, South America, and developed nations. Strategies for managing congenital cataracts must be adapted and developed according to regional conditions. A basic framework for acceptable outcomes must focus on developing systems to address the critical components of education, access, quality care, and good follow-up. PMID:25892047

  17. Congenital cytomegalovirus infection: new prospects for prevention and therapy.

    Cytomegalovirus is the commonest congenital viral infection in the developed world, with an overall prevalence of approximately 0.6%. Approximately 10% of congenitally infected infants have signs and symptoms of disease at birth, and these symptomatic infants have a substantial risk of subsequent neurologic sequelae. These include sensorineural hearing loss, mental retardation, microcephaly, development delay, seizure disorders, and cerebral palsy. Antiviral therapy for children with symptomatic congenital cytomegalovirus infection is effective at reducing the risk of long-term disabilities and should be offered to families with affected newborns. An effective preconceptual vaccine against CMV could protect against long-term neurologic sequelae and other disabilities.

    Nasal and upper respiratory tract obstruction in the neonatal period can result from a variety of conditions, and may be present with variable symptoms. Salivary gland anlage tumor, also referred as congenital pleomorphic adenoma, is a very rare benign congenital tumor of the nasopharynx, which may produce nasal obstruction and other associated, nonspecific symptoms. We report a case of congenital salivary gland anlage tumor causing a severe neonatal respiratory distress with pulmonary hypertension. The tumor was removed and the outcome was favourable without recurrence at five years of the follow up.

    Singing out of tune characterizes congenital amusia. Here, we examine whether an aid to memory improves singing by studying vocal imitation in 11 amusic adults and 11 matched controls. Participants sang a highly familiar melody on the original lyrics and on the syllable /la/ in three conditions. First, they sang the melody from memory. Second, they sang it after hearing a model, and third, they sang in unison with the model. Results show that amusic individuals benefit from singing by imitation, whether singing after the model or in unison with the model. The amusics who were the most impaired in memory benefited most, particularly when singing on the syllable /la/. Nevertheless, singing remains poor on the pitch dimension; rhythm was intact and unaffected by imitation. These results point to memory as a source of impairment in poor singing, and to imitation as a possible aid for poor singers. PMID:21864199

    Almost all the rubeolic reinfections are not apparent and are without any risk for the fetus. The news born's case (2nd in children) which is described here, presents a bilateral cataract. We have found positive IgA, IgG and IgM and an antibodies avidity of 70%. Concerning the mother, there are no IgM. The IgM and IgA are positive. The avidity of the antibodies is upper than 90%. During her first pregancy, the mother was subjected to the search of the antibodies, the results are positive (title = 60 ul/ml) and during her second pregnancy, the mother had rubeollic contact with her eldest son. Our conclusion is that it is a congenital rubella resulting from a reinfection. PMID:11256312
