Pectus excavatum  

Microsoft Academic Search

One of the more common chest wall anomalies seen in children is pectus excavatum, which may present at birth, or more commonly during the teenage growth spurt. Symptoms of lack of endurance, shortness of breath with exercise, or chest pain are frequent. Although pectus excavatum may be a component of some uncommon syndromes, patients usually are healthy. Evaluation should include

Pectus excavatum in blunt chest trauma: a case report  

PubMed Central

Introduction Blunt cardiac rupture is an exceedingly rare injury. Case presentation We report a case of blunt cardiac trauma in a 43-year-old Caucasian German mother with pectus excavatum who presented after a car accident in which she had been sitting in the front seat holding her two-year-old boy in her arms. The mother was awake and alert during the initial two hours after the accident but then proceeded to hemodynamically collapse. The child did not sustain any severe injuries. Intraoperatively, a combined one-cm laceration of the left atrium and right ventricle was found. Conclusion Patients with pectus excavatum have an increased risk for cardiac rupture after blunt chest trauma because of compression between the sternum and spine. Therefore, patients with pectus excavatum and blunt chest trauma should be admitted to a Level I Trauma Center with a high degree of suspicion.

Method of pectus excavatum measurement based on structured light technique  

NASA Astrophysics Data System (ADS)

We present an automatic method for assessment of pectus excavatum severity based on an optical 3-D markerless shape measurement. A four-directional measurement system based on a structured light projection method is built to capture the shape of the body surface of the patients. The system setup is described and typical measurement parameters are given. The automated data analysis path is explained. Their main steps are: normalization of trunk model orientation, cutting the model into slices, analysis of each slice shape, selecting the proper slice for the assessment of pectus excavatum of the patient, and calculating its shape parameter. We develop a new shape parameter (I3ds) that shows high correlation with the computed tomography (CT) Haller index widely used for assessment of pectus excavatum. Clinical results and the evaluation of developed indexes are presented.

Compromised cardiac function in exercising teenagers with pectus excavatum.  

PubMed

Patients with pectus excavatum complain about fatigue, tachypnea, discomfort and dyspnea, but the existence of an equivalent underlying pathophysiology has been questioned. We investigated 75 teenagers (49 pectus excavatum patients and 26 age matched controls) at rest and during bicycle exercise at submaximal exercise levels. At rest cardiac function was determined using echocardiography. During rest and exercise, cardiac output, heart rate and aerobic exercise capacity were measured using photo-acoustic gas-rebreathing technique for non-invasive determination of the cardiopulmonary function. At rest, no cardiac differences were found between control subjects and patients with pectus excavatum. During submaximal exercise, cardiac index was lower 6.6(6.3-7.0) l/min/m(2) among the pectus patients as compared to the control subjects 8.0(7.3-8.8) l/min/m(2), P=0.0001. The lower cardiac output among the pectus patients was due to a lower stroke index 42(39-45) ml/beat/m(2) as compared to controls 54(44-64) ml/beat/m(2), P=0.0022, whereas heart rate was unchanged. Cardiac function is significantly impaired at submaximal exercise level compared to healthy age matched controls. PMID:21788301

A 13-year-old neutered female Labrador retriever had inspiratory dyspnea secondary to bilateral laryngeal paralysis. Radiographically, there was pectus excavatum with a mediastinal shift to the right. Arytenoid lateralization was performed, relieving the upper respiratory obstruction, and the sternal deformity also resolved. Chronic upper respiratory obstruction should be considered in dogs with pectus excavatum. Furthermore, correction of upper respiratory obstruction has the potential to result in resolution of pectus excavatum. PMID:22145690

A 4-year-old girl with pectus excavatum (PE), multiple prior respiratory infections, tracheomalacia and tracheal compression due to the innominate artery was referred for surgical evaluation. Aortopexy was deemed unlikely to improve airway diameter due to her chest concavity. Thoracoscopy-assisted PE repair was performed, resulting in marked improvement in the anteroposterior diameter of the trachea and resolution of her respiratory symptoms. Durability of the PE correction at 2 and 7 years following bar removal was demonstrated radiographically. PMID:23708973

Brugada Phenocopy in a Patient with Pectus Excavatum: Systematic Review of the ECG Manifestations Associated with Pectus Excavatum.

Brugada phenocopies (BrP) have emerged as new clinical entities that are etiologically distinct from true Brugada syndrome (BrS). BrP are characterized by an ECG pattern that is phenotypically identical to true BrS (type 1 or type 2); however, BrP are caused by various other factors such as mechanical mediastinal compression, myocardial ischemia, pericarditis, myocarditis, pulmonary embolism, and metabolic disturbances. We report a case of an electrocardiographic BrP in a patient with pectus excavatum deformity in the absence of true BrS using currently defined BrP diagnostic criteria. A systematic review of ECG manifestations associated with pectus excavatum is also discussed. PMID:24047484

Long term cardiopulmonary effects of closed repair of pectus excavatum.  

PubMed

The closed or "Nuss" repair of pectus excavatum is widely accepted for correction of moderate to severe deformities. Patients typically report significant subjective improvements in pulmonary symptoms, and short and medium term evaluations (up to 2 years with the bar in place) suggest modest improvement to cardiac function but a decrease in pulmonary function. This study examined the effects at 3 months post-bar removal of closed repair of pectus on pulmonary function, exercise tolerance and cardiac function. Patients were followed prospectively after initial evaluation for operation. All patients underwent preoperative and post-bar removal evaluation with CT scan, complete pulmonary function and exercise testing to anaerobic threshold, as well as echocardiogram. Twenty-six patients have completed the follow up protocol. Preoperative CT index was 4.5 +/- 1.3, average age at operation was 13.2 years, and average tanner stage was 3.5 +/- 0.5. At 3 months or greater follow-up post-bar removal, patients reported an improvement in subjective ability to exercise and appearance (P < 0.05 by wilcoxin matched pairs). Objective measures of FEV1, total lung capacity, diffusing lung capacity, O(2) pulse, VO(2max), and respiratory quotient all showed significant improvement compared to preoperative values, while normalized values of cardiac index at rest did not (All values normalized for height and age, comparisons P < 0.05 by student's paired t test). These results demonstrate a sustained improvement in cardiopulmonary function after bar removal following closed repair of pectus excavatum. These findings contrast with results from previous studies following the open procedure, or with the closed procedure at earlier time points; the long term physiological effects of closed repair of pectus excavatum include improved aerobic capacity, likely through a combination of pulmonary and cardiac effects.

Surgical correction of pectus excavatum in two cats  

PubMed Central

Two sexually intact male Bengal cats, one a 4-month-old weighing 2.8 kg and the other, a 3-month-old weighing 2.0 kg, were presented to the University of Missouri-Columbia Veterinary Teaching Hospital for evaluation of respiratory distress. On initial presentation, both cats were dyspneic, exercise intolerant, and had marked concave deformation of the caudal sternum. Surgical correction of pectus excavatum was performed using a cylindrical external splint and U-shaped external splint. Post-operative thoracic radiography revealed that there was decreased concavity of the sternum and increased thoracic height at the level of the caudal sternebrae in both cats.

Mechanical factors play an important role in pectus excavatum with thoracic scoliosis  

PubMed Central

Background This study investigated the incidence, imaging characteristics and mechanical factors in scoliotic patients with pectus excavatum. Methods A total of 142 scoliostic patients with pectus excavatum were evaluated prior to operation. The evaluation included a complete physical exam, phenotype and severity of the pectus excavatum, incidence and severity of scoliosis, and analysis of radiological images, including calculation of the Haller index. Results Twenty five out of 142 patients (17.61%) with pectus excavatum had scoliosis with a Cobb angle >10 degrees, and in 80.00% of the cases the spinal column was bent to the right. Seventeen patients had bent-to-the-right spines that involved the 6th to 10 th thoracic vertebrae. We found that 23 out of 25 patients with a Cobb angle more than 10° were teenagers and adults. The incidence of scoliosis was only 6.06% in the children under 11 years whereas it was 21.79% in the teenage group. Conclusions Mechanical forces appear to play a role in the coexistence of pectus excavatum and scoliosis. There is a relationship between age, severity (Haller index), asymmetry and scoliosis. The heart and mediastinum play a role in providing an outward force to the left of the sternum which may be an important reason for the coexistence of pectus excavatum and scoliosis, but the correlation needs further proof.

This is the first published report of a dog with dynamic right ventricular outflow tract (infundibular) stenosis, right ventricular hypertrophy, and pectus excavatum. A juvenile dog presented with a grade V/VI left base systolic heart murmur, tachycardia, and pectus excavatum. Diagnosis of the aforementioned conditions was based on radiography, electrocardiography, and echocardiography. At 9 1/2 wk of age the heart murmur was no longer audible and the right ventricular stenosis and hypertrophy had dissipated and regressed, respectively. Resolution may be associated with growth of the dog. A good prognosis is foreseen.

Virtual simulation of the postsurgical cosmetic outcome in patients with Pectus Excavatum  

NASA Astrophysics Data System (ADS)

Pectus excavatum is the most common congenital deformity of the anterior chest wall, in which several ribs and the sternum grow abnormally. Nowadays, the surgical correction is carried out in children and adults through Nuss technic. This technic has been shown to be safe with major drivers as cosmesis and the prevention of psychological problems and social stress. Nowadays, no application is known to predict the cosmetic outcome of the pectus excavatum surgical correction. Such tool could be used to help the surgeon and the patient in the moment of deciding the need for surgery correction. This work is a first step to predict postsurgical outcome in pectus excavatum surgery correction. Facing this goal, it was firstly determined a point cloud of the skin surface along the thoracic wall using Computed Tomography (before surgical correction) and the Polhemus FastSCAN (after the surgical correction). Then, a surface mesh was reconstructed from the two point clouds using a Radial Basis Function algorithm for further affine registration between the meshes. After registration, one studied the surgical correction influence area (SCIA) of the thoracic wall. This SCIA was used to train, test and validate artificial neural networks in order to predict the surgical outcome of pectus excavatum correction and to determine the degree of convergence of SCIA in different patients. Often, ANN did not converge to a satisfactory solution (each patient had its own deformity characteristics), thus invalidating the creation of a mathematical model capable of estimating, with satisfactory results, the postsurgical outcome.

Effects of the Nuss procedure on chest wall kinematics in adolescents with pectus excavatum.  

PubMed

No data are available on the effects of the Nuss procedure on volumes of chest wall compartments (the upper rib cage, lower rib cage and abdomen) in adolescents with pectus excavatum. We used optoelectronic plethysmography to provide a quantitative description of chest wall kinematics before and 6 months after the Nuss procedure at rest and during maximal voluntary ventilation in 13 subjects with pectus excavatum. An average 11% increase in chest wall volume was accommodated within the upper rib cage (p=0.0001) and to a lesser extent within the abdomen and lower rib cage. Tidal volumes did not significantly change during the study. The repair effect on chest wall kinematics did not correlate with the Haller index of deformity at baseline. Six months of the Nuss procedure do increase chest wall volume without affecting chest wall displacement and rib cage configuration. PMID:22688019

Variation of the Anthropometric Index for pectus excavatum relative to age, race, and sex  

PubMed Central

OBJECTIVES: To determine possible variations in the Anthropometric Index for pectus excavatum relative to age, race, and sex in individuals free of thoracic wall deformities. METHODS: Between 2002 and 2012, 166 individuals with morphologically normal thoracic walls consented to have their chests and the perimeter of the lower third of the thorax measured according to the Anthropometric Index for pectus excavatum. The participant characteristics are presented (114 men and 52 women; 118 Caucasians and 48 people of African descent). RESULTS: Measurements of the Anthropometric Index for pectus excavatum were statistically significantly different between men and women (11–40 years old); however, no significant difference was found between Caucasians and people of African descent. For men, the index measurements were not significantly different across all of the age groups. For women, the index measurements were significantly lower for individuals aged 3 to 10 years old than for individuals aged 11 to 20 years old and 21 to 40 years old; however, no such difference was observed between women aged 11 to 20 years old and those aged 21 to 40 years old. CONCLUSION: In the sample, significant differences were observed between women aged 11 to 40 years old and the other age groups; however, there was no difference between Caucasian and people of African descent.

A four-directional body shape measurement system and its application for pectus excavatum severity assessment  

NASA Astrophysics Data System (ADS)

The paper presents an optical three-dimensional shape measurement system and an automatic method for assessment of pectus excavatum severity based on the measurement results. The measurement system consists of four directional modules utilizing structured light projection method (namely temporal phase shifting TPS and modified Gray code projection) to capture the shape of body surface of the patients. The measurement result is a three-dimensional point cloud representing the skin surface. The system setup is described and the typical measurement parameters are given. The automated data analysis path is explained. Its main stages are: point cloud segmentation, normalization of trunk orientation, cutting the model into slices, analysis of each slice shape, selecting the proper slice for the assessment of pectus excavatum of the patient and calculating its shape parameter. The analysis does not require any initial processing (e.g. surface fitting or mesh building) as it is conducted on raw 3-D point cloud data resulting from the measurement. A new shape parameter (I3ds) was developed that shows correlation with CT Haller Index widely used for assessment of pectus excavatum. Preliminary clinical results are presented.

We report the case of a 14-year-old boy with pectus excavatum and mild scoliosis. The patient underwent a minimally invasive Nuss repair with excellent cosmetic result. He returned 3 weeks post-operatively with bilious emesis and a 3.6-kg weight loss (5.5% of total body weight). Radiographic evaluation was consistent with the diagnosis of superior mesenteric artery syndrome and the child ultimately required nasojejunal feedings. Following return to his baseline weight, he was transitioned to oral feedings and has done well in follow-up. This is the first report of SMA syndrome following minimally invasive pectus excavatum repair. PMID:23164012

External longitudinal titanium support for the repair of complex pectus excavatum in adults.  

PubMed

Several techniques exist for the repair of complex pectus excavatum. The placement of retrosternal metal bars improves the results by reducing the recurrence rate, but entails several possible risks, complications and disadvantages. A new method, specifically conceived for the repair of severe, asymmetric forms in adult patients, is reported. The corrected bone is fixed in the proper position by two, patient-customized, titanium struts, externally screwed to the manubrium and sternal body. Any retrosternal bar is thus avoided, reducing possible complications, without hampering the chest wall dynamic. In this particularly difficult issue, this technique provides long-term good functional, mechanical and cosmetic results and does not entail a second surgery for struts removal. PMID:22927563

Pain and Anxiety Management in Minimally Invasive Repair of Pectus Excavatum  

PubMed Central

The Nuss procedure for the correction of Pectus Excavatum (PE) is associated with intense postoperative pain. Our strategy to control early postoperative pain is to combine epidural with intravenous analgesia. Our aim was to analyse our pain control strategy by reviewing all the PE cases treated at our institution. Sixty consecutive patients, aged between 12 and 26 years old, received the PE operation at our institution from January, 2007 to September, 2010. The median age was 16 (12-27) with a male/female ratio of about 7/1. An epidural catheter was employed in all the cases, with 38 patients (63%) requiring additional drugs to control pain, which remained in place for 74 hours (72-96). The pain score was higher in male patients, but lower in those younger than 16 years old. Moreover, patients that consumed benzodiazepines had a significant decrease in cumulative opioid intake (P = 0.0408). Both gender and age had an impact on pain control, while we noticed a synergistic effect between opiates and tranquillizers.

Pectus excavatum postsurgical outcome based on preoperative soft body dynamics simulation  

NASA Astrophysics Data System (ADS)

Pectus excavatum is the most common congenital deformity of the anterior chest wall, in which an abnormal formation of the rib cage gives the chest a caved-in or sunken appearance. Today, the surgical correction of this deformity is carried out in children and adults through Nuss technic, which consists in the placement of a prosthetic bar under the sternum and over the ribs. Although this technique has been shown to be safe and reliable, not all patients have achieved adequate cosmetic outcome. This often leads to psychological problems and social stress, before and after the surgical correction. This paper targets this particular problem by presenting a method to predict the patient surgical outcome based on pre-surgical imagiologic information and chest skin dynamic modulation. The proposed approach uses the patient pre-surgical thoracic CT scan and anatomical-surgical references to perform a 3D segmentation of the left ribs, right ribs, sternum and skin. The technique encompasses three steps: a) approximation of the cartilages, between the ribs and the sternum, trough b-spline interpolation; b) a volumetric mass spring model that connects two layers - inner skin layer based on the outer pleura contour and the outer surface skin; and c) displacement of the sternum according to the prosthetic bar position. A dynamic model of the skin around the chest wall region was generated, capable of simulating the effect of the movement of the prosthetic bar along the sternum. The results were compared and validated with patient postsurgical skin surface acquired with Polhemus FastSCAN system.

Assessment of psychosocial functioning and its risk factors in children with pectus excavatum  

PubMed Central

Background Psychosocial functioning is poor in patients with pectus excavatum (PE). However, a comprehensive understanding of this issue does not exist. The aim of this study was to assess the severity of psychosocial problems as associated with PE, as well as to identify its risk factors. Methods A comparative study was performed at the Sichuan Academy of Medical Sciences/Sichuan Provincial People's Hospital in Chengdu, China. Patients age 6 to 16 who admitted to the outpatient department for the evaluation or treatment for PE were included in the study. In addition to parental reports of child psychosocial problems on the Achenbach Child Behavior Checklist (CBCL), parents also filled in other structured questionnaires, including socio-demographic variables, patients' medical and psychological characteristics. The severity of malformation was assessed by CT scan. For comparison, an age- and gender- matched control group was recruited from the general population. The socio-demographic and scores on CBCL were compared between patients and control subjects. Univariate and multivariate analysis were performed to examine risk factors for psychosocial problems in patients. Results No statistically significant differences were found with respect to social-demographic variables between children with PE and control subjects. Compared with control subjects, children with PE displayed higher prevalence of psychosocial problems in the different scales of the CBCL questionnaire such as 'withdraw', 'anxious-depressed', 'social problems' and 'total problems'. Both univariate and multivariate analyses suggested that age, severity of malformation, and being teased about PE were significantly associated with patients' psychosocial problems. Conclusions The information derived from this study supports the opinion that children with PE have more psychosocial problems than children from the general population. Multiple medical and psychosocial factors were associated with patients' impairment of psychosocial functioning.

Genetic Linkage Localizes an Adolescent Idiopathic Scoliosis and Pectus Excavatum Gene to the 18q Chromosome  

PubMed Central

Study Design A single large family, in which adolescent idiopathic scoliosis (AIS) and pectus excavatum (PE) segregate as an autosomal dominant condition, was evaluated. Genome-wide linkage analysis and candidate gene sequencing were performed. Objective To map the disease-causing locus in a large Caucasian family in which AIS and PE co-segregate. Summary of Background Data AIS and PE are common musculoskeletal conditions known to have a genetic component, though few genes have been identified for either. Genetic studies have been confounded by a lack of large families in which the disorders segregate. Methods Clinical examinations were performed on the proband, who underwent posterior spinal fusion, and twelve additional affected family members. To map a gene causing AIS and PE, a genome-wide linkage analysis was performed with the Affymetrix Mapping 10K XbaI array on thirteen affected and ten unaffected family members. Candidate genes were sequenced. Results AIS was present in thirteen female family members and PE was present in three males and one female. Genome-wide linkage analysis resulted in a linkage peak on chromosome 18q with a maximum parametric multipoint logarithm of the odds (LOD) score of 3.86. Recombinants delineated the critical genetic region to an interval of 6.4 cM between SNP_A-1519369 and SNP_A-1507702, corresponding to a 7.06 Mb region (hg18: chr18:26342508-34395660). The chromosome 18q linkage region contains more than 30 genes. Re-sequencing of the coding regions of 21 candidate genes in the region did not reveal any causative mutation. Conclusion Linkage analysis in this large family demonstrated a novel locus for AIS and PE on chromosome 18q. Because of the increased frequency of PE in family members of AIS patients, consideration of family members with PE as affected may increase the power of AIS genetic linkage studies.

Patient Satisfaction Following Minimally Invasive Repair of Pectus Excavatum: Single Surgeon Experience  

PubMed Central

Background: Pectus excavatum (PE) is the most common chest wall deformity in adolescent life. Nuss procedure is a well-established technique for the repair of PE. The indication for correction is mainly medical aesthetic. Advantages of Nuss over conventional methods include reduced length of hospital stay, smaller incisions, and absence of need for osteochondrectomies. Here, we describe our experience with this procedure. Materials and Methods: This was a retrospective study of patients who underwent Nuss procedure by a single surgeon between 2006 and 2010 in a regional center. Indications for surgery included the following: Progressive deformity and psychological stress. All patients underwent chest X-ray and pulmonary function testing. A standard Nuss procedure was performed using a single bar. Patients’ satisfaction was assessed by a questionnaire and follow-up clinic letters. Satisfaction with body image was scored on a scale of 1-10. Results: Eleven patients with PE underwent correction by Nuss procedure. Mean age of the patient was 19 years (range: 15-30). The average hospital stay was 7 days (range: 4-23 days). There was no mortality and no episodes of wound infection. In the immediate post-operative period, three patients (12.5%) were noted to have poor pain control. The post-operative course was uneventful in all cases except one patient who developed lung collapse, pleural effusion, and bar dislocation. Hundred percent of patients were satisfied with the scar. Seven patients scored 7 out of 10 on satisfaction with body image and two patients scored 6 or less. None of the patients complained of chronic pain. Conclusion: Nuss procedure is an effective method for the correction of PE. Most patients were satisfied with the outcome and none experienced chronic pain.

Brace Compression for Treatment of Pectus Carinatum  

PubMed Central

Background Surgery has been the classical treatment of pectus carinatum (PC), though compressive orthotic braces have shown successful results in recent years. We propose a non-operative approach using a lightweight, patient-controlled dynamic chest-bracing device. Materials and Methods Eighteen patients with PC were treated between July 2008 and June 2009. The treatment involved fitting of the brace, which was worn for at least 20 hours per day for 6 months. Their degree of satisfaction (1, no correction; 4, remarkable correction) was measured at 12 months after the initiation of the treatment. Results Thirteen (72.2%) patients completed the treatment (mean time, 4.9±1.4 months). In patients who completed the treatment, the mean overall satisfaction score was 3.73±0.39. The mean satisfaction score was 4, and there was no recurrence of pectus carinatum in patients who underwent the treatment for at least 6 months. Minimal recurrence of pectus carinatum after removal of the compressive brace occurred in 5 (38.5%) patients who stopped wearing the compressive brace at 4 months. Conclusion Compressive bracing results in a significant improvement in PC appearance in patients with an immature skeleton. However, patient compliance and diligent follow-up appear to be paramount for the success of this method of treatment. We currently offer this approach as a first-line treatment for PC.

Sub-axillary access with the use of costal cartilages articulated bars for correction of pectus carinatum.  

PubMed

We describe an original technique for correction of pectus carinatum (PC) through a limited sub-axillary incision by chondrectomy and the use of costal cartilages articulated bars to stabilize the chest wall. We have developed this technique in order to improve the cosmetic results in the surgical treatment of even complex sterno-chondral deformities. The surgical incision is made along the lateral edge of the pectoralis major muscle in the sub-axillary region and its length is related to the number of costal cartilages to be treated. This technique is principally indicated for asymmetric PC with unilateral deformities of the costal cartilages, but its application can be extended to bilateral alteration of the parasternal cartilages by performing the sub-axillary incision bilaterally. When more than four cartilages are removed, the chest is stabilized by articulated bars made using cylindrical fragments obtained by the division of the removed costal cartilages. This thoracoplasty technique performed with a minimally invasive sub-axillary access is simple and safe. It allows the effective treatment of severe PC with either unilateral asymmetric or bilateral costal cartilages deformities, avoiding the median sternal incision and the use of the metallic bar.

Management of Congenital Chest Wall Deformities  

PubMed Central

Congenital chest wall deformities are considered to be anomalies in chest wall growth. These can be categorized as either rib cage overgrowth or deformities related to inadequate growth (aplasia or dysplasia). Rib cage overgrowth leads to depression of the sternum (pectus excavatum) or protuberance of the sternum (pectus carinatum) and accounts for greater than 90% of congenital chest wall deformities. The remaining deformities are a result of inadequate growth. Evolution in the management of congenital chest wall deformities has made significant progress over the past 25 years. This article will review chest wall deformities and the current management strategies of these interesting anomalies.

Recurrent chest wall anomalies.  

PubMed

Chest wall anomalies are a heterogeneous group of malformations requiring repair. Recurrence and the need for secondary repair may occur. Congenital anomalies, including bifid sternum, pentalogy of Cantrell, Jeunes's syndrome and Poland's anomaly, rarely recur. Pectus carinatum may recur in the original surgical area or an adjacent area and most often recurs in patients who undergo repair before completion of teenage growth. Pectus excavatum may recur in approximately 5% of patients. Simple recurrence, floating sternum, or Acquired Jeune's syndrome may result. All of these would require reoperation. Each chest wall anomaly recurrence requires an individualized approach to timing and type of repair. Overall excellent results should be obtained for operative repair of recurrences. PMID:12728394

A simple idea for approximating the volume of filler needed for chest-wall contour-defects.  

PubMed

Fillers can be used to correct contour-defects. Due to the irregularities of defects, estimating the volume of filler required can be difficult. This frequently results in surgeons taking a step-wise approach to filler-injection, usually occurring over different appointments. Using a patient with pectus excavatum as an example, we provide a simple tip as to estimating the volume of filler required. In this case, normal saline was poured into the chest-wall defect until the adequate level was reached (from the lateral aspect), while noting how much liquid was used. The patient then had a comparable volume of filler injected. PMID:22938009

Prevalence of Swimming Puppy Syndrome in 2,443 Puppies during the Years 2006-2012 in Thailand  

PubMed Central

The purpose of this study was to report on the prevalence of swimming puppy syndrome (SPS) and investigate predisposing factors. Data were recorded from 2,443 puppies (1,183 males and 1,260 females) in Thailand, October 2006–September 2012, including breed, sex, number of puppies per litter, type of nest floor, number of affected limbs, and occurrence of pectus excavatum. Fifty-two puppies (2.13%) were diagnosed with SPS. The breed most frequently affected was English Bulldog (8.33%). There was no significant difference (P > 0.05) between presence and absence of disease based on sex, breed, and nest floor type. The number of puppies per litter was associated with SPS; puppies from smaller litters (1.92?±?1.12) had a higher prevalence of the disease (P < 0.01) than puppies from larger litters (3.64?±?2.24). Moreover, 15.38% of puppies with affected limbs showed signs of pectus excavatum (8/52); this clinical sign was more prevalent (P < 0.01) in puppies with all four limbs affected with SPS.

[Correction of the congenital malformations of the front chest wall by the modelling technique of sternochondroplasty: technique and results on a series of 14 cases].  

PubMed

In the congenital malformations of the front chest wall showing depression or protrusion, the cardiorespiratory disorders are inconstant and often not linked with the distortion. On the other hand psychoaffective repercussions are major in adolescents and young adults justifying recourse to surgery with morphological and aesthetic aiming. The authors present the technique of modelling sternochondroplasty by raising with osteosynthesis by slide fastener-handle of Martin-Borrelly, applied to the correction of congenital malformation of the front chest wall in young adult, both of protrusion (pectus carinatum), of thoraxes in funnel (pectus excavatum) types or of mixed types (pectus arcuatum). This surgical replanning intervention is carried out by under-mammary way and aims at reestablishing a normal anatomy of the front chest wall. It leads to a genuine wide sternochondrocostal volet, which is stabilised by a specific, multipurpose, adaptable and reliable osteosynthesis equipment. The results obtained on a series of 14 cases are good or excellent in 86% of the cases and stable over time in the absence of major complications. A good cooperation of the patient is essential to obtain a good result in particular via the continuation of musculation exercises after assembly consolidation, possibly associated with remote mammary plastic surgery in the event of hypoplasia or of associated mammary agenesia.

Eurysternum (extra-wide sternum)--a rarely recognized developmental anomaly. Scintigraphic appearances.  

PubMed

A rarely recognized extra-wide sternum was demonstrated by Tc-99m methylene diphosphonate bone scans in two adult patients. One patient was a 53-year-old man with prostate cancer who had no sternal symptoms or known sternal deformity. The second patient was a 41-year-old man with carcinoma of the lung whose extra-wide sternum was associated with a pectus excavatum deformity involving the lower half of the mesosternum (corpus sternum). A proper name for this developmental abnormality, "eurysternum" (eury-Greek word meaning broad; wide), is suggested. Two other patients, one with another type of wide sternum and another with a mesosternal foramen (fenestra sternii) deformity are also described. Related embryology and developmental anatomy of the sternum are reviewed. PMID:7788985

Genome wide SNP array analysis revealed a 3.57 Mb de novo microdeletion in band q12.3 of chromosome 8. The long lasting sleep disorders turned out to originate from a rare juvenile epilepsy, continuous spike-waves during slow sleep (CSWS) syndrome, that includes the electrical status epilepticus in sleep (ESES) phenomenon. MRI-scanning of the brain showed no abnormalities. To the authors knowledge, this is the first report of a de novo 8q12.3q13.2 microdeletion syndrome that presents with ESES/CSWS. PMID:22138216

Marfan syndrome with acute abdomen: a case report  

PubMed Central

Introduction Marfan syndrome is an autosomal dominant connective tissue disorder characterized by a combination of clinical manifestations in different organ systems. Patients with Marfan syndrome (MFS) whose lifetimes are extended may be encountered as acute abdomen (appendicitis) cases apart from the obligatory reasons and emergencies arising naturally out of their disease, as in the case reported. Case presentation In a 28-year-old Turkish male, arachnodactyly, pectus excavatum, kyphoscoliosis and, according to pulmonary roentgenogram, a density increase in the left apical field were detected. In addition, according to the echocardiographic examination, Ebstein’s anomaly, mitral valve prolapse, pulmonary hypertension, and inferior deficiency of mitral, aorta, and tricuspid valves were present. The patient was planned to be operated on with the prediagnosis of acute abdomen. Conclusion Taking into consideration the pathologies that may accompany MFS and the probable future complications, the patients must be closely monitored during anesthesia applications and required measures should be taken beforehand.

Minimally invasive thoracic surgery in pediatric patients: the taiwan experience.  

PubMed

Minimally invasive technology or laparoscopic surgery underwent a major breakthrough over the past two decades. The first experience of thoracoscopy in children was reported around 1980 for diagnosis of intrathoracic pathology and neoplasia. Up until the middle of the 1990s, the surgical community in Taiwan was still not well prepared to accept the coming era of minimally invasive surgery. In the beginning, laparoscopy was performed in only a few specialties and only relatively short or simple surgeries were considered. But now, the Taiwan's experiences over the several different clinical scenarios were dramatically increased. Therefore, we elaborated on the experience about pectus excavatum: Nuss procedure, primary spontaneous hemopneumothorax, thoracoscopic thymectomy, and empyema in Taiwan. PMID:23819123

Lipid storage myopathy with clinical markers of Marfan syndrome: A rare association.  

PubMed

Disorders of lipid metabolism can cause variable clinical presentations, often involving skeletal muscle, alone or together with other tissues. A 19-year-old boy presented with a 2-year history of muscle pain, cramps, exercise intolerance and progressive weakness of proximal lower limbs. Examination revealed skeletal markers of Marfan syndrome in the form of increased arm span compared with height, Kyphoscoliois, moderate pectus excavatum, high arched palate and wrist sign. He also had mild neck flexor weakness and proximal lower limb weakness with areflexia. Pathologic findings revealed lipid-laden fine vacuoles in the muscle fibers. Possibility of carnitine deficiency myopathy was considered and the patient was started on carnitine and Co Q. The patient made remarkable clinical improvement over the next 2 months. This case is reported for rarity of the association of clinical markers of Marfan syndrome and lipid storage myopathy and sparse literature on lipid storage myopathy in the Indian context.

The management of anterior chest wall deformity in patients presenting for breast augmentation.  

PubMed

Anterior chest wall asymmetry is sometimes encountered in patients presenting for consideration of breast augmentation. The chest wall asymmetry or deficiency may be significant enough to consider reconstruction at the same time as breast augmentation in a small number of cases. Customized and prefabricated chest wall implants have been used in a variety of conditions including Poland syndrome, pectus excavatum, and sunken anterior chest. Careful moulage preparation and on-table implant modification are needed to "seat" these implants on the skeletal chest wall under the pectoralis major muscle. The chest wall implant provides a base for the subsequent breast prostheses and fills up a bony deficit that cannot be camouflaged by the breast prostheses alone. PMID:11932625

Prognostic factors in multiple myeloma: definition of risk groups in 410 previously untreated patients: a Grupo Argentino de Tratamiento de la Leucemia Aguda study.  

PubMed

Four hundred ten previously untreated multiple myeloma patients entered onto two consecutive Grupo Argentino de Tratamiento de la Leucemia Aguda (GATLA) protocols were analyzed to identify significant prognostic factors influencing survival. The univariate analysis selected the following variables: performance status, renal function, percentage of bone marrow plasma cells at diagnosis, hemoglobin, and age. A multivariate analysis showed that performance status, renal function, percentage of bone marrow plasma cells, hemoglobin, and age were the best predictive variables for survival. A score was assigned to each patient according to these variables, which led to their classification in three groups: good, intermediate, and poor risk, with a probability of survival of 26% and 10% at 96 months, and 5% at 56 months, and median survival of 60, 37, and 14 months, respectively (P = .0000). In our patient population, this model proved to be superior to the Durie-Salmon staging system in defining prognostic risk groups, and separating patients with significantly different risks within each Durie-Salmon stage.

Homozygous frameshift mutation in TMCO1 causes a syndrome with craniofacial dysmorphism, skeletal anomalies, and mental retardation  

PubMed Central

We identified an autosomal recessive condition in 11 individuals in the Old Order Amish of northeastern Ohio. The syndrome was characterized by distinctive craniofacial dysmorphism, skeletal anomalies, and mental retardation. The typical craniofacial dysmorphism included brachycephaly, highly arched bushy eyebrows, synophrys, long eyelashes, low-set ears, microdontism of primary teeth, and generalized gingival hyperplasia, whereas Sprengel deformity of scapula, fusion of spine, rib abnormities, pectus excavatum, and pes planus represented skeletal anomalies. The genome-wide homozygosity mapping using six affected individuals localized the disease gene to a 3.3-Mb region on chromosome 1q23.3-q24.1. Candidate gene sequencing identified a homozygous frameshift mutation, c.139_140delAG, in the transmembrane and coiled-coil domains 1 (TMCO1) gene, as the pathogenic change in all affected members of the extended pedigree. This mutation is predicted to result in a severely truncated protein (p.Ser47Ter) of only one-fourth the original length. The TMCO1 gene product is a member of DUF841 superfamily of several eukaryotic proteins with unknown function. The gene has highly conserved amino acid sequence and is universally expressed in all human tissues examined. The high degree of conservation and the ubiquitous expression pattern in human adult and fetal tissues suggest a critical role for TMCO1. This report shows a TMCO1 sequence variant being associated with a genetic disorder in human. We propose “TMCO1 defect syndrome” as the name of this condition.

Partial trisomy 8p (8p11.2-->pTER) and deletion of 13q (13q32-->qTER): case report.  

PubMed

We report a female infant with partial trisomy 8p (8p11.2-->pter) and deletion of 13q (13q32-->qter). She was born with mild hypotonia, intrauterine growth retardation, microcephaly, micrognathia, large low set ears, pectus excavatum, anteriorly placed anus, and bilateral clinodactyly. Echocardiography showed left ventricular hypertrophy, bicuspid aortic valve, dilatation of the aorta and pulmonary artery, and prolapse of atrio-venticular valve leaflets. Cytogenetic investigation of her sister and her father showed that the altered region resulted from a balanced translocation between the part of the long arm of chromosome 13 and short arm of chromosome 8. In partial trisomy 8p, the clinical picture of the patients comprises hypotonia, structural brain abnormalities, facial anomalies including a large mouth with a thin upper lip, a high arched palate, a broad nasal bridge, an abnormal maxilla or mandible, malformed, low set ears, and orthopedic anomalies. Although patients with proximal deletions of 13q that do not extend into band q32 have mild to moderate mental and growth delays with variable minor anomalies, patients with more distal deletions including at least part of band q32 usually have major malformations such as retinoblastoma, mental-motor growth retardation, malformation of brain and heart, anal atresia, and anomalies of the face and limbs. To our knowledge partial trisomy 8p and partial monosomy of 13q have not been reported previously in the same person. PMID:21614986

Anesthetic management of a child with both Marfan syndrome and Turner syndrome.  

PubMed

Marfan syndrome is an autosomal dominant heritable disorder of the connective tissue that involves primarily the skeletal, ocular, and cardiovascular systems. Turner syndrome is a genetic disorder resulting from partial or complete X chromosome monosomy. We report the anesthetic management of a case of Marfan-Turner syndrome, which is the first such case to appear in the literature to our knowledge. A 3 year old ASA III girl was scheduled to undergo minor plastic surgery. She had a short webbed neck, prognathism, micrognathia, low-set ears, and a high palate. Her anterior and posterior facial heights were long. She had growth retardation, pectus excavatum, and joint laxity. She also had high-degree mitral insufficiency, mitral valve prolapse, and an atrial septal defect. After sevoflurane induction, the airway was secured using a size 2 LMA without any difficulty in the spontaneously breathing patient. Her blood pressure was within normal limits, no arrthymia occurred, and anesthesia was uneventful. Special care should be given to syndromic patients. Prior medical evaluations and any prior anesthetic history can help to focus preoperative evaluations and planning. Preoperatively targeting relevant organ systems, any anatomic or laboratory abnormalities that can be optimized, and perioperative airway management are all key to a successful outcome.

A t(5;16)(p15.32;q23.3) generating 16q23.3 --> qter duplication and 5p15.32 --> pter deletion in two siblings with mental retardation, dysmorphic features, and speech delay.  

PubMed

We report on two siblings (half brothers on the paternal side) with a syndrome consisting of delayed development, cardiac anomalies, chest deformity, hip rotation, metatarsus adductus, genital hypoplasia, dysmorphic face, depressed nasal bridge, mental retardation, and speech delay. All metaphases examined showed a normal karyotype in the patients, their father, and both mothers. High-resolution array CGH examination revealed a 16q (6 Mb) duplication dup(16)(16q23.3 --> 16qter) and a 5p (0.97 Mb) terminal deletion del(5)(p15.32 --> pter) in both affected boys but not their healthy siblings or parents. Interphase fluorescence in situ hybridization (FISH) confirmed both the 16q duplicated region and the 5p terminal deletion. Clinical abnormalities in the patients included thin upper lip, clinodactyly, and foot deformity, which were reported previously with duplications in 16q23.3. Pectus excavatum, hip rotation, metatarsus adductus, umbilical hernia, brachycephaly, and esotropia were not reported previously in chromosome 16q duplications but may be features that occur intermittently. The 5p deleted region has been associated previously only with speech delay, which was present in both patients. These patients display certain phenotypic characteristics not reported previously in 16q duplication and confirm 5p terminal deletion as an important chromosome anomaly for speech delay.

Interstitial Deletions at 6q14.1q15 Associated with Developmental Delay and a Marfanoid Phenotype  

PubMed Central

There are a number of reports of interstitial deletions of the long arm of chromosome 6 that have developmental delay and obesity suggesting that this is a distinct phenotype almost like Prader-Willi syndrome. Here we report a patient with a similar deletion but a strikingly different phenotype, one more in keeping with Marfan syndrome, although he does not fulfil the criteria for that syndrome. Array comparative genomic hybridization was performed to investigate a patient with a striking phenotype. This revealed an interstitial deletion of 6q14.1q15. Parental FISH studies were normal, indicating that this is a de novo deletion. Our patient has a completely different phenotype compared to other patients reported to have similar deletions. The common feature is developmental delay, but the body features are quite different in that our patient is tall, strikingly thin with pectus excavatum, scoliosis, skin striae, arachnodactyly, pes planus, cataracts, and a high-arched palate. This contrasts with other patients who have a similar deletion but have short stature and obesity. 6q14.1q15 interstitial deletions can have a very variable phenotype and do not necessarily conform to a clinical recognizable microdeletion syndrome caused by haploinsufficiency of dosage-sensitive genes in that region as proposed by others.

A new X-linked dysplasia gigantism syndrome: follow up in the first family and report on a second Austrian family.  

PubMed

We report on a new X-linked recessive syndrome in 2 unrelated families, consisting of pre- and postnatal growth excess, typical facial phenotype allowing diagnosis at birth, and usually normal physical and intellectual development. The minor anomalies seen at birth include a "coarse" face with wide nasal bridge, short nose with upturned nasal tip, wide open mouth, thick lips, midline depression of the lower lip, enlarged tongue, highly arched palate, large maxilla and jaw, and a short broad neck. Voice is hoarse and affected individuals have a plump, stocky body with pectus excavatum, thoracic scoliosis, hepatosplenomegaly, umbilical and/or inguinal hernias, broad short hands and feet, and in some cases preauricular dimples, abnormal ears, postaxial hexadactyly, hypoplastic index finger nails, and abnormal dermatoglyphics. Early postnatal death is frequent and pathogenetically unexplained. During infancy and childhood the leading manifestations are the overgrowth (greater than 97th centile), striking facial appearance, hypodontia and/or malposition of teeth, genua valga, hypoplastic calf muscles, and clumsiness. Adolescent and adult patients have well proportioned "gigantism" of athletic build (192-210 cm), large "coarse" face, and a deep voice. General intellectual and motor development are either normal or mildly delayed. Results of routine laboratory tests are normal, as are growth hormone and IGF I levels and chromosomes. Pathogenesis remains unknown. Heterozygotes may show some of the characteristic facial changes. PMID:3177454

Bronchus cardiacus accessorius dexter.  

PubMed

The diagnosis of bronchus cardiacus accessorius dexter (BCAD) has occurred in 25 cases during the bronchoscopic investigations of 30,000 adult patients of the authors. In most of the cases, this bronchial anomaly has been revealed as an accessory phenomenon, nevertheless, in one of the patients, it was the source of a considerable hemorrhage. In another case reported here in detail, it occurred together with multiple developmental anomalies, such as tracheobronchomegaly, mitral valve prolapse, pectus excavatum, hypoplasy of sinus frontalis on the right side, inguinal hernia on the left side and hyperlipidemia type IV. Family analysis did not confirm the presence of any chromosomal disorders or accumulation of similar developmental anomalies. The forms and frequency of associations of the anomalies are surveyed on the basis of literary data. The recognition of BCAD is of diagnostic importance, since it may explain the persistence of some bronchopulmonary symptoms; furthermore, the exploration of the associated abnormal vascular branches may be very useful in case of an eventual thoracic surgical intervention.

Patterns of pulmonary perfusion scans in normal subjects  

SciTech Connect

A vital factor conditioning the usage of the pulmonary perfusion (Q) scan in the evaluation of patients suspected of pulmonary embolism is the prevalence of abnormal Q scans in subjects free of cardiopulmonary disease. Because this prevalence has not been well defined, we performed Q scans in 80 nonsmoking subjects 18 to 29 yr of age having no known active cardiopulmonary disease. Each subject underwent a history, physical examination, electrocardiogram, spirometry, and PA chest roentgenogram, followed by a 6-view Q scan. Two subjects in whom a Q defect was suspected underwent a /sup 133/Xe equilibrium-washout ventilation (V) scan. All Q scans were interpreted blindly and independently by 2 experienced readers. Seventy-nine of the 80 Q scans were read as normal. No subject demonstrated a lobar or segmental defect. One of the 80 subjects, who had a mild pectus excavatum, had a left upper lobe subsegmental defect, which was not seen on the V scan. Based on the statistical analysis of these data, no more than 3.68% of normal nonsmoking persons in this age group may have a lobar or segmental Q scan defect and no more than 6.77% may have a subsegmental defect (with 95% confidence). Therefore, our study indicated that Q scan defects, particularly lobar or segmental, are rarely present among normal nonsmokers in this age group.

Prevalence of Olfactory and Other Developmental Anomalies in Patients with Central Hypogonadotropic Hypogonadism  

PubMed Central

Introduction: Hypogonadotropic hypogonadism (HH) is a heterogeneous disease caused by mutations in several genes. Based on the presence of hyposmia/anosmia it is distinguished into Kallmann syndrome (KS) and isolated HH. The prevalence of other developmental anomalies is not well established. Methods: We studied 36 patients with HH (31 males, 5 females, mean age 41.5), 9 with familial and 27 with sporadic HH (33 congenital, 3 adult-onset), by physical examination, smell test (BSIT Sensonics), audiometry, renal ultrasound, and magnetic resonance imaging of the olfactory structures. Results: Based on the smell test, patients were classified as normosmic (n?=?21, 58.3%) and hypo/anosmic (n?=?15, 41.6%). Hypoplasia/agenesis of olfactory bulbs was found in 40% of patients (10/25; 75% hypo/anosmic, 7.6% normosmic, p?pectus excavatum, bimanual synkinesis, iris coloboma, and absent nasal cartilage. Anamnestically 4/31 patients reported cryptorchidism (25% hypo/anosmic, 5.2% normosmic, p?=?NS). Conclusion: Hypo/anosmia is significantly related to anatomical anomalies of the olfactory bulbs/tracts but the prevalence of other developmental anomalies, especially midline defects and neurosensorial hearing loss, is high both in HH and KS and independent of the presence of anosmia/hyposmia. From the clinical standpoint KS and normosmic HH should be considered as the same complex, developmental disease.

Chromosome 10q tetrasomy: First reported case  

SciTech Connect

While there are several reports of trisomy 10q (at least 35), we are not aware of previous cases of 10q tetrasomy. We present what we believe to be the initial report of such a case. R.J. is a 6 1/2 year old white male who presented with multiple dysmorphic features, marked articulation problems, hyperactivity, and developmental delays. He is the product of a term uncomplicated pregnancy. There was a normal spontaneous vaginal delivery with a birth weight of 6 lbs. 4oz. and length was 19 1/2 inch. Dysmorphic features include small size, an asymmetrically small head, low set ears with overfolded helixes, bilateral ptosis, downslanting eyes, right eye esotropia, prominent nose, asymmetric facies, high palate, mild pectus excavatum deformity of chest, and hyperextensible elbow joints. The patient is in special needs classes for mildly mentally handicapped students. Chromosome analysis at a resolution of 800 bands revealed a complex rearrangement of chromosomes 10 and 11. The segment 10q25.3 to q16.3 appears to be inverted and duplicated within the long arm of chromosome 10 at band q25.3 and the same segment of chromosome 10 is present on the terminal end of the short arm of chromosome 11. There is no visible loss of material from chromosome 11. Fluorescence in situ hybridization was performed with a chromosome 10 specific {open_quotes}paint{close_quotes} to confirm that all of the material on the abnormal 10 and the material on the terminal short arm of 11 was from chromosome 10. Thus, it appears that the segment 10q25.3 to q26.3 is present in four copies. Parental chromosome studies are normal. We compared findings which differ in that the case of 10q tetrasomy did not have prenatal growth deficiency, microphthalmia, cleft palate, digital anomalies, heart, or renal defects. Whereas most cases of 10q trisomy are said to have severe mental deficiency, our case of 10q tetrasomy was only mildly delayed. We report this first apparent cited case of 10q tetrasomy.

Increasing social capital via local networks: analysis in the context of a surgical practice.  

PubMed

The relationship between social capital (support, trust, patient awareness, and increased practice revenue) and local networks (university hospital) in communities has received little attention. The development of computer-based communication networks (social networks) has added a new dimension to the argument, posing the question of whether local networks can (re-)create social capital in local communities. This relationship is examined through a review of the literature on local networks and social capital and a surgeon's practice management from 1990 to 2001 with respect to repair of pectus chest deformities. With respect to pectus repair there was a consistent but small number of new referrals (15-20 new patients/year), lack of patient awareness (eight to 12 self-referred patients/year), and modest practice revenue. Since the inception of an Internet website (social network) dedicated to pectus repair in 1996 there has been increased social participation (n = 630 hits/year to the website); facilitation of spread of information through E-mail messages (n = 430 messages/year); and a greater participation of groups such as women, minorities, adults, and those with disability (n = 120 patients/year). The dissemination of information via the local network has also allowed an "outward movement" with increased participation by interconnecting communities (n = 698,300 global Internet participants based on statistical ratios). We conclude that local networks have enhanced social networks providing new grounds for the development of relationships based on choice and shared interest. PMID:12356148

PubMed Central

In this study, we report for the first time the use of silica-coated superparamagnetic iron oxide nanoparticles (SPION) as contrast agents in biomedical photoacoustic imaging. Using frequency-domain photoacoustic correlation (the photoacoustic radar), we investigated the effects of nanoparticle size, concentration and biological media (e.g. serum, sheep blood) on the photoacoustic response in turbid media. Maximum detection depth and the minimum measurable SPION concentration were determined experimentally. The nanoparticle-induced optical contrast ex vivo in dense muscular tissues (avian pectus and murine quadricept) was evaluated and the strong potential of silica-coated SPION as a possible photoacoustic contrast agents was demonstrated.

Primary angioplasty vs. fibrinolysis in very old patients with acute myocardial infarction: TRIANA (TRatamiento del Infarto Agudo de miocardio eN Ancianos) randomized trial and pooled analysis with previous studies  

PubMed Central

Aims To compare primary percutaneous coronary intervention (pPCI) and fibrinolysis in very old patients with ST-segment elevation myocardial infarction (STEMI), in whom head-to-head comparisons between both strategies are scarce. Methods and results Patients ?75 years old with STEMI <6 h were randomized to pPCI or fibrinolysis. The primary endpoint was a composite of all-cause mortality, re-infarction, or disabling stroke at 30 days. The trial was prematurely stopped due to slow recruitment after enroling 266 patients (134 allocated to pPCI and 132 to fibrinolysis). Both groups were well balanced in baseline characteristics. Mean age was 81 years. The primary endpoint was reached in 25 patients in the pPCI group (18.9%) and 34 (25.4%) in the fibrinolysis arm [odds ratio (OR), 0.69; 95% confidence interval (CI) 0.38–1.23; P = 0.21]. Similarly, non-significant reductions were found in death (13.6 vs. 17.2%, P = 0.43), re-infarction (5.3 vs. 8.2%, P = 0.35), or disabling stroke (0.8 vs. 3.0%, P = 0.18). Recurrent ischaemia was less common in pPCI-treated patients (0.8 vs. 9.7%, P< 0.001). No differences were found in major bleeds. A pooled analysis with the two previous reperfusion trials performed in older patients showed an advantage of pPCI over fibrinolysis in reducing death, re-infarction, or stroke at 30 days (OR, 0.64; 95% CI 0.45–0.91). Conclusion Primary PCI seems to be the best reperfusion therapy for STEMI even for the oldest patients. Early contemporary fibrinolytic therapy may be a safe alternative to pPCI in the elderly when this is not available. Clinicaltrials.gov # NCT00257309.

The foraminiferal assemblages of 5 vibracores from Isles Dernieres on the Louisiana coast indicate significant environmental shifts within the past 1000 years. The cores, 2 offshore and 3 from the back barrier region, represent mainly the progradational phase of the Early Lafourche delta. Overall, Ammonia parkinsoniana and Elphidium excavatum dominate the faunas, except those of marshes and low-salinity interdistributary bays. However, a cluster analysis of species frequencies demonstrate that 5 past environments can be distinguished on the basis of some minor constituents of the assemblages. In both offshore cores, Elphidium poeyanum, Buliminella morgani, and Quinqueloculina seminulum are common in the basal, prodelta part; a reducing environment is indicated by pyrite-filled tests. A low-diversity transition zone above this is characterized by a 85-90% dominance of Ammonia parkinsoniana and Elphidium excavatum. Two delta front environments are represented in the top part of these cores. Elphidium discoidale, E. galvestonense, Hanzawaia concentrica, and Ammontium salsum are common in both, but the species diversity is lower in the upper, shallow-water facies. Marsh and low-salinity interdistributary bay facies, represented in the onshore cores, are characterized by the dominance of agglutinated species. The facies changes in the onshore cores are more complex and represent shorter time spans than in the offshore cores.

Modern foraminiferal facies in a subtropical estuarine channel, Bertioga, São Paulo, Brazil  

USGS Publications Warehouse

Numerical analyses of modern foraminiferal abundance and environmental data from the Bertioga Channel (Sa??o Paulo, Brazil) reveal multiple biofacies within an overall paralic setting. Despite its fisheries, mariculture and attraction to tourists, the environmental state of Bertioga Channel remains poorly studied. The present investigation is an attempt to partly fill this gap; the parameters examined include depth, salinity, temperature, organic carbon, sulfur content and bottom sediment type. Muddy sediments with high organic carbon content derived from land drainage are found in the inner parts of the channel, whereas sandy sediment dominates the areas adjacent to the Atlantic Ocean. In the eastern entrance to the channel, sandy sediment contain species of Rotaliida from Facies 1 (including Elphidium discoidale, Elphidium poeyanum, Hanzawaia boueana, Pararotalia cananeiaensis and Nonionella atlantica), reflecting normal marine salinity. Sediments with high percentages of silt and clay in polyhaline and eurybaline environments of the eastern part and Itapanhau?? River contain Facies 2, which includes Ammonia beccarii and Pararotalia cananeiaensis. In the western entrance and central, western and eastern parts, where salinities vary from 18 to 30 psu and the sediments contain both low and high organic carbon, the foraminifera from Facies 3 are dominated by Quinqueloculina milletti, Arenoparrella mexicana, Pararotalia cananeiaensis, Ammonia beccarii, Buliminella elegantissima, Elphidium sp., Elphidium excavatum, Elphidium gunteri and Elphidium poeyanum. In mesohaline and polyhaline waters of the central part, the organic-carbon-rich silt and clay contain Facies 4, which includes Ammonia beccarii, Pararotalia cananeiaensis, Elphidium excavatum and Elphidium sp. Most of organic-carbon-enriched, silty-clay substrates that are subject to the highest fresh-water discharge and high bottom temperatures support two different assemblages: one of mostly Rotaliina and the other mostly of Textulariida (Facies 5 and 6). Facies 5 includes Ammonia beecarii, Elphidium excavatum, Arenoparrella mexicana, Haplophragmoides wilberti, Siphotrochammina lobata, Trochammina inflata and Trochammina sp., all of which are typical of mesohaline sites (mainly Crumau?? and Trindade rivers), and Facies 6 includes Bolivina sp., Ammoastuta salsa, Arenoparrella mexicana, Haplophragmoides wilberti and Trochammina sp., all of which are typical of oligohaline and mesohaline mangrove fringes. The foraminiferal species from the present study are frequently found in paralic environments in Brazil, western Africa and other estuaries around the world.

Safe intubation in Morquio-Brailsford syndrome: A challenge for the anesthesiologist  

PubMed Central

Morquio-Brailsford syndrome is a type of mucopolysaccharidoses. It is a rare disease with features of short stature, atlantoaxial instability with risk of cord damage, odontoid hypoplasia, pectus carinatum, spine deformities, hepatomegaly, and restrictive lung disease. Neck movements during intubation are associated with the risk of quadriparesis due to cervical instability. This, along with the distortion of the airway anatomy due to deposition of mucopolysaccharides makes airway management arduous. We present our experience in management of difficult airway in a 3-year-old girl with Morquio-Brailsford syndrome posted for magnetic resonance imaging and computerized tomography scan of a suspected unstable cervical spine. As utmost sagacity during intubation is required, the child was intubated inside operation theatre in the presence of experienced anesthesiologists and then shifted to the peripheral location. Intubation was done with an endotracheal tube railroaded over a pediatric fibreoptic bronchoscope passed through the lumen of a classic laryngeal mask airway, keeping head in neutral position.

Unilateral spinal anaesthesia in a patient with Osteogenesis Imperfecta with a lower leg fracture: a case report.  

PubMed

Osteogenesis Imperfecta is a rare, genetically determined disease with several possible complications in anaesthesia. Anaesthesiologists therefore pay special attention to the treatment of patients suffering from Osteogenesis Imperfecta since they commonly suffer from a difficult airway and intraoperative positioning difficulties. We report here the case of unilateral spinal anaesthesia in a patient suffering from Osteogenesis Imperfecta type I. A 28-year-old patient diagnosed with Osteogenesis Imperfecta type I was admitted to the hospital due to lower leg fracture requiring surgical treatment. The patient had blue sclerae, triangular-shaped face, macroglossia, scoliosis of thoracic and lumbar parts of the spine, pectus carinatum and thrombocytopenia. Upon the correction of thrombocytopenia, unilateral spinal anaesthesia with hyperbaric levobupivacain was chosen in order to avoid possible complications typical for general anaesthesia. Consequently, unilateral spinal anaesthesia with a customized local anesthetic could be consdered as a safe anesthetic method for such patients. PMID:24060019

Complete monosomy mosaic of chromosome 21: case report and review of literature.  

PubMed

Complete monosomy mosaic of chromosome 21 is a rare disorder. The syndromic features are highly variable. This study describes a girl of Mexican origin with complete monosomy 21 in mosaicism with novel findings, including cortical atrophy, macrostomia, pectum excavatum and immune deficiencies. Parental karyotypes were normal. FISH analysis with probes from 21q22.1-q22.2 region and centromere of X DNA probe was performed on peripheral blood lymphocytes whereas 21q22.1-q22.2 and 21q, 4p, 4q subtelomeric DNA probes were tested in fibroblasts. We propose that the monosomy 21 mosaicism is the cause of the survival of children with more than 4 months of age. PMID:22985727

Tick paralysis: first zoonosis record in Egypt.  

PubMed

Tick paralysis caused by the secretion of toxin with saliva while taking a blood meal is an important veterinary disease, but is rare in humans. Although it has certain geographical proclivities, it exists worldwide. Tick paralysis was demonstrated for the first time in Egypt among four children living in rural area at Giza Governorate. The clinical pictures were confused with rabies; myasthensia gravis; botulism; diphtheritic polyneuropathy encountered in rural areas. The recovery of tick infesting the four little children and negative clinical and laboratory data of all diseases denoted tick paralysis. The encountered ticks infesting their animals were Rhipicephalus sanguineus on dogs, Hyalomma dromedarii on camels and Hyalomma anatolicum excavatum and Haemaphysalis sp. on goats. The case was recognized as first record of tick paralysis in Egypt. PMID:22662597

Isolation and purification procedures for the preparation of paralytic shellfish poisoning toxin standards.  

PubMed

Paralytic shellfish poisoning (PSP) is caused by mixtures of saxitoxin analogs of which more than eighteen are known. Reliable and sensitive analytical methods and assays for these toxins are essential to protect the consumer and the shellfish industry, but research has been restricted by a shortage of the pure compounds. Only saxitoxin has so far been generally available as a PSP toxin standard, yet sulfated analogs usually occur in higher concentrations than saxitoxin in toxic marine algae and shellfish. Methods are described for the purification of some of the common PSP toxins, in quantities sufficient for the preparation of PSP standards from the dinoflagellate Alexandrium excavatum, the giant sea scallop (Placopecten megallanicus) hepatopancreas, and the cyanobacterium Aphanizomenon flos-aquae. Purity was monitored by high performance liquid chromatography with fluorescence detection (HPLC-FD), ionspray mass spectrometry (ISP-MS), capillary electrophoresis (CE), and proton NMR spectroscopy.

High-resolution foraminiferal, isotopic, and trace element records from holocene estuarine deposits of San Francisco Bay, California  

USGS Publications Warehouse

A 3.5-m gravity core (DJ6-93SF-6) from San Francisco Bay reveals a complex paleoclimatic history of the region over the last 3870 cal YBP. A polynomial equation based on 11 AMS 14C ages provides an excellent age model for the core, and environmental proxies for water temperature and salinity are derived from various foraminiferal abundances, stable carbon and oxygen isotopes, and Mg/Ca ratios. Two foraminiferal associations were identified by Q-mode cluster analysis: a colder-water Elphidium excavatum association and the warmer-water Ammonia beccarii-Elphidium gunteri association. The E. excavatum association dominates the core for all but about 600 years out of the last four millennia. At 3870 cal YBP, water temperatures were warm (13.9??C) and freshwater inflow was reduced compared with today. From 3590 to 2860 cal YBP, temperatures dropped 0.5??C and the climate remained dry. This was followed by a period of pronounced lower ??13C values, indicating that conditions became considerably wetter from 2860 to 2170 cal YBP. During this interval, the temperature oscillated frequently, peaking at 13.9??C at 2710 cal YBP, then dropping shortly thereafter to 12.8??C at 2420 cal YBP. Freshwater inflow gradually decreased between 2170 and 1950 cal YBP with a minimal rise in temperature, then changed quickly to colder and wetter conditions at 1900 cal YBP. Drier conditions then prevailed until 1480 cal YBP with water temperatures fluctuating between 13.1??C and 13.8??C, followed by wetter climate from 1480 to 1320 cal YBP. A significant faunal shift from the E. excavatum association to the A. beccarii-E. gunteri association occurred from 1250 to 650 cal YBP, possibly due to regional warming, decreased oxygen availability, and/or a change in the phyto-plankton community. Associated with this change in faunal composition were warm and dry conditions, representative of the Medieval Warm Period (Medieval Climatic Anomaly). A climatic shift coincident with the onset of the Little Ice Age (LIA I and LIA II) is evident from 650 to 280 cal YBP, with the return of the E. excavatum association and an extreme drop in ??18O values, all indicating increased precipitation and fresh water inflow. This was followed by generally drier conditions to the present, except for a brief wet period around 100 cal YBP, and fairly consistent water temperatures in the middle 13??C, except for a drop to 12.8??C at 200 cal YBP. Two significant faunal changes occur near the top of the core. First, there is the reappearance of the A. beccarii-E. gunteri association, suggesting that, once again, regional warming has taken place, oxygen availability has declined, and/or environmental conditions changed such that diatoms have become a scarce food source. Second, there is the first appearance of the invasive Japanese foraminifera Trochammina hadai Uchio, a species that commonly lives in highly polluted areas and is an indicator of eutrophication in its native estuaries. At the same time, freshwater inflow decreased, which may be explained by global warming during the last 100 years, or more likely due to modern water diversion for agriculture in the central valley of California.

Benthic foraminifera distribution in a tourist lagoon in Rio de Janeiro, Brazil: a response to anthropogenic impacts.  

PubMed

Rodrigo de Freitas Lagoon, located in the Rio de Janeiro City, receives several types of polluted discharges. The knowledge of the sediment microfauna correlated with heavy metal and organic matter concentrations could supply important data about the conditions of the lagoon. The benthic foraminiferal assemblage presented larger diversity and more abundant samples in the lagoon entrance than in the inner area. The Ammonia tepida - Elphidium excavatum foraminiferal assemblage is characterized by dwarf, corroded and weak organisms. Agglutinated species were found only near the entrance. Low abundance values and sterility of five samples in the inner area (north/northeast) can be caused by high levels of heavy metals and organic matter. A. tepida shows negative correlation with increasing heavy metals values. PAHs and coprostanol high indexes, and the absence or low presence of microfauna in samples around the lagoon margin confirm illegal flows from gas stations and domestic sewage. PMID:21871637

Rib Cage Deformities Alter Respiratory Muscle Action and Chest Wall Function in Patients with Severe Osteogenesis Imperfecta  

PubMed Central

Background Osteogenesis imperfecta (OI) is an inherited connective tissue disorder characterized by bone fragility, multiple fractures and significant chest wall deformities. Cardiopulmonary insufficiency is the leading cause of death in these patients. Methods Seven patients with severe OI type III, 15 with moderate OI type IV and 26 healthy subjects were studied. In addition to standard spirometry, rib cage geometry, breathing pattern and regional chest wall volume changes at rest in seated and supine position were assessed by opto-electronic plethysmography to investigate if structural modifications of the rib cage in OI have consequences on ventilatory pattern. One-way or two-way analysis of variance was performed to compare the results between the three groups and the two postures. Results Both OI type III and IV patients showed reduced FVC and FEV1 compared to predicted values, on condition that updated reference equations are considered. In both positions, ventilation was lower in OI patients than control because of lower tidal volume (p<0.01). In contrast to OI type IV patients, whose chest wall geometry and function was normal, OI type III patients were characterized by reduced (p<0.01) angle at the sternum (pectus carinatum), paradoxical inspiratory inward motion of the pulmonary rib cage, significant thoraco-abdominal asynchronies and rib cage distortions in supine position (p<0.001). Conclusions In conclusion, the restrictive respiratory pattern of Osteogenesis Imperfecta is closely related to the severity of the disease and to the sternal deformities. Pectus carinatum characterizes OI type III patients and alters respiratory muscles coordination, leading to chest wall and rib cage distortions and an inefficient ventilator pattern. OI type IV is characterized by lower alterations in the respiratory function. These findings suggest that functional assessment and treatment of OI should be differentiated in these two forms of the disease.

100 Years of benthic foraminiferal history on the inner Texas shelf inferred from fauna and stable isotopes: Preliminary results from two cores  

NASA Astrophysics Data System (ADS)

Coastal regions, such as the Texas-Louisiana shelf, are subject to seasonal hypoxia that strongly depends on the magnitude of freshwater discharge from local and regional river systems. We have determined benthic foraminiferal fauna and isotopic compositions in two 210Pb dated box cores (BR4 and BR5) to examine the evidence for nearshore hypoxia and freshwater discharge on the Texas shelf during the last 100 years. The 210Pb chronologies of both cores reveal sedimentation rates of 0.2 and 0.1 cm yr-1, translating to ˜60 and ˜90 year records. The fauna of both cores were almost exclusively composed of Ammonia parkinsoniana and Elphidium excavatum, indicating euryhaline ambient waters. The Ammonia-Elphidium (A-E) index, a qualitative measure of low oxygen conditions, shows an increase from values between 20 and 50 to near 100 in both cores, suggesting low oxygen conditions between 1960 and the core top. Between 1950 and 1960 (9-10 cm), low A-E values in BR4 coincide with high ?18O and ?13C values greater than 0‰ and -1‰ respectively. This event corresponds to severe drought (the Texas Drought of Record) over the Brazos River drainage basin and considerably reduced river discharge from 1948 to 1957. High A-E values prior to this event imply low-oxygen conditions were prevalent prior to anthropogenic exacerbation of Louisiana shelf hypoxia and at least since the dredging of a new Brazos River delta in 1929. Elphidium excavatum ?13C values are very low (-4‰) and indicative of significant vital effect. The ?13C values of A. parkinsoniana average -3‰ and exhibit little variability, most likely reflecting pore waters influenced by aerobic and anaerobic respiration. The association of lowered Brazos River discharge with more oxygenated shelf bottom waters suggests Brazos River discharge and shelf hypoxia are linked, but the influence of Mississippi-Atchafalaya discharge can also contribute to shelf stratification.

Paleoenvironmental changes during the past 2000 years, evidence from Kongsfjorden, Svalbard  

NASA Astrophysics Data System (ADS)

Over the past decades the Arctic has received more attention due to the rapid warming that is more pronounced there than elsewhere on the globe. Instrumental time series are too short to capture the range of natural variability in the Arctic and we therefore have to rely on proxy records to describe the whole range of natural variability. In this context the late-Holocene climate variations are particularly important because natural forcings and the Earth's boundary conditions have been approximately similar to those operating today. Documenting past natural climate variability has therefore a vital role to play in understanding the present climate and predicting future change. Here we present a high resolution marine record from Kongsfjorden covering the last c. 2000 years. The core site is located in Kongsfjorden situated on the western coast of Spitsbergen (Svalbard). We focus on this region because it lies along the path of inflow of warmer and saline subsurface waters via the West Spitsbergen Current which is one of the important heat sources for the Arctic Ocean. This current is a major regulator of environmental changes and for example sea-ice distribution in the west Svalbard area. Therefore quantification of it's spatially and temporally variations through time are essential for understanding past environmental and climate changes. We have investigated faunal variations in benthic foraminifera from the upper 60 cm (covering the last two millennia) of a gravity core (510 cm total length) sampled with one-cm density. Chronology of the gravity core is established by AMS radiocarbon dating. The core was in addition investigated for grain size analysis and x-ray. The sediment analysis and x-ray show the upper part of the core contains large amounts of IRD from 7 cm - 25 cm corresponding to an age of 150-700 cal yr. It indicates that abundant icebergs melted over the core site depositing IRD. Further down core (1000-1800 cal yr) there is a significant dominance of fine grained sediment and decrease in ice rafting indicating less influence from glaciers. The foraminiferal species composition show decreasing content of agglutinated foraminifera down core caused by their low preservation potential. For this core site it confirms the importance of calcareous foraminifera as a fossil record tool. The two dominant species in the core are Elphidium excavatum and Nonionellina labradorica. During the last 2000 years the percentage of E. excavatum shows a general tendency to decrease while N. labradorica increases toward present. Elphidium excavatum is typical for arctic glaciomarine environments close to glaciers and ice caps, indicating harsh conditions (cold bottom waters temperatures, lower salinity) and probably extensive ice cover. Nonionellina labradorica indicates the vicinity of oceanographic fronts and high productivity. Another species Islandiella spp., often associated with increased productivity and presence of the sea ice edge, shows significant increase in percentage from 1000 to 800 cal yr BP. From 600 to 400 cal yr BP Bucella spp. start to decline suggesting increased sea ice cover and diminished influence of the Coastal Current on the inner shelf of Svalbard.

Lack of segregation of a Marfan-like phenotype associating marfanoie habitus and mitral valve disease with fibrillin gene on chromosome 15  

SciTech Connect

Apart from typical Marfan syndrome (MS), several Marfan-like conditions are known. One of those is the MASS syndrome (Mitral involvement, Aortic dilatation, Skin and Skeletal abnormalities) defined by Pyeritz et al. Among these, a dominantly inherited mitral valve prolapse with marfanoid habitus have also been reported. Until now, except for a Marfan-like condition described by Boileau et al., all Marfan families are linked to fib 15. A large Belgian pedigree with 25 affected patients among 62 at risk subjects spanning four generations is described. A syndrome including marfanoid skeletal dysplasia (tall stature, dolichostenomelia, arachnodactyly, pectus carinatum joint dislocation), prolapse and/or myxomatous degeneration of the mitral valve, but without aortic dilatation of eye involvement was observed. Although the phenotype fulfills Berlin diagnostic criteria for MS, it closely resembles MASS syndrome. Preliminary linkage results show discordance aggregation insertion in the fib 15 gene, as evaluated by intragenic microsatellite fib 15. Since Dietz et al. described a similar patient with fib 15 gene, we suggest that this variant of Marfan syndrome is genetically heterogeneous and caused by mutations, some of which are allelic to classical Marfan syndrome plus a subtype, some of which are not. Linkage studies are under way to further characterize the gene involved in the present family.

In vitro and ex vivo evaluation of silica-coated super paramagnetic iron oxide nanoparticles (SPION) as biomedical photoacoustic contrast agent  

NASA Astrophysics Data System (ADS)

The employment of contrast agents in photoacoustic imaging has gained significant attention within the past few years for their biomedical applications. In this study, the use of silica-coated superparamagnetic iron oxide (Fe3O4) nanoparticles (SPION) was investigated as a contrast agent in biomedical photoacoustic imaging. SPIONs have been widely used as Food-and-Drug-Administration (FDA)-approved contrast agents for magnetic resonance imaging (MRI) and are known to have an excellent safety profile. Using our frequency-domain photoacoustic correlation technique ("the photoacoustic radar") with modulated laser excitation, we examined the effects of nanoparticle size, concentration and biological medium (e.g. serum, sheep blood) on its photoacoustic response in turbid media (intralipid solution). Maximum detection depth and minimum measurable SPION concentration were determined experimentally. The detection was performed using a single element transducer. The nanoparticle-induced optical contrast ex vivo in dense muscular tissues (avian pectus) was evaluated using a phased array photoacoustic probe and the strong potential of silicacoated SPION as a possible photoacoustic contrast agent was demonstrated. This study opens the way for future clinical applications of nanoparticle-enhanced photoacoustic imaging in cancer therapy.

Dysregulation of FHL1 spliceforms due to an indel mutation produces an Emery-Dreifuss muscular dystrophy plus phenotype.  

PubMed

Emery-Dreifuss muscular dystrophy (EDMD) is characterised by early-onset joint contractures, progressive muscular weakness and wasting and late-onset cardiac disease. The more common X-linked recessive form of EDMD is caused by mutations in either EMD (encoding emerin) or FHL1 (encoding four and a half LIM domains 1), while mutations in LMNA (encoding lamin A/C), SYNE1 (encoding nesprin-1) and SYNE2 (encoding nesprin-2) lead to autosomal dominant forms of the condition. Here, we identify a three-generation family with an extended EDMD phenotype due to a novel indel mutation in FHL1 that differentially affects the relative expression of the three known transcript isoforms produced from this locus. The additional phenotypic manifestations in this family-proportionate short stature, facial dysmorphism, pulmonary valvular stenosis, thoracic scoliosis, brachydactyly, pectus deformities and genital abnormalities-are reminiscent of phenotypes seen with dysregulated Ras-mitogen-activated protein kinase (RAS-MAPK) signalling [Noonan syndrome (NS) and related disorders]. The misexpression of FHL1 transcripts precipitated by this mutation, together with the role of FHL1 in the regulation of RAS-MAPK signalling, suggests that this mutation confers a complex phenotype through both gain- and loss-of-function mechanisms. This indel mutation in FHL1 broadens the spectrum of FHL1-related disorders and implicates it in the pathogenesis of NS spectrum disorders. PMID:23456229

Arterial tortuosity and aneurysm in a case of Loeys-Dietz syndrome type IB with a mutation p.R537P in the TGFBR2 gene.  

PubMed

We report a 13-year-old girl with Loeys-Dietz syndrome (LDS) caused by a known transforming growth factor beta receptor II (TGFBR2) gene mutation, who developed aortic root dilatation and saccular aneurysm of the internal carotid artery. LDS is a rare, autosomal dominant aortic aneurysm syndrome with multisystem involvement. The disease is typically characterized by the triad of arterial tortuosity and aneurysms, hypertelorism, and bifid uvula/cleft palate. The characteristic LDS symptoms observed in the reported case included craniofacial dysmorphism (hypertelorism, cleft palate, blue sclerae, malar hypoplasia, retrognathia), skeletal deformities (scoliosis, talipes equinovarus, pectus deformity, arachnodactyly), congenital heart defects (patent ductus arteriosus, PDA), and arterial tortuosity and aneurysms. Molecular genetic testing revealed a heterozygous mutation (c.1610 G>C, p.R528C) in the serine-threonine kinase domain of the TGFBR2 gene. Magnetic resonance (MR) angiography showed aortic dilatation, tortuosity of bilateral supraaortic arteries, and saccular aneurysm on the right cervical internal carotid artery. LDS resembles Marfan-related disorders (Marfan, Shprintzen-Goldberg and vascular Ehlers-Danlos syndrome), but arterial tortuosity and aneurysms are characteristic for LDS, so a timely diagnosis of LDS is important for early diagnosis and intervention of aneurysms to prevent vascular events. Here, we describe a LDS patient who presented with arterial tortuosity and saccular aneurysm. PMID:22734312

Phylloid pattern of pigmentary disturbance in a case of complex mosaicism.  

PubMed

Among the various types of pigmentary disturbances associated with mosaicism, the phylloid pattern (Greek phyllon = leaf, eidos = form) is characterized by multiple leaf-like patches reminiscent of an art nouveau painting. The number of cases displaying this unusual pattern is so far limited. We describe a phylloid pattern of hypomelanosis in a 3-year-old girl with multiple congenital anomalies including microcephaly, midfacial hypoplasia, cleft lip, coloboma, posteriorly rotated ears, pectus carinatum, and pronounced mental and physical retardation. In addition, this child had oval or oblong patches of hyperpigmentation involving the trunk in a horizontal arrangement dissimilar from the phylloid hypomelanotic pattern. In peripheral blood lymphocytes a karyotype 46,XX,-13,+t(13q;13q) was consistently found, whereas cultured skin fibroblasts showed a complex form of mosaicism comprising three different abnormal cell lines (46,XX,-13,+t(13q;13q)/45,XX,-13/45,XX,-13,+frag). This case provides further evidence that the phylloid pattern represents a separate category of pigmentary disturbance to be distinguished from other types of cutaneous mosaicism such as the lines of Blaschko or the checkerboard arrangement.

Menkes syndrome: a case report.  

PubMed

Menkes syndrome is caused by mutation of ATP7A gene that encode copper-binding membrane protein localized to the trans-Golgi membrane. Mutation of this gene causes defective exportation of copper from the cell. Intracellular accumulation of copper does not reach the toxic state, as copper entering the body is trapped in the intestinal epithelium. Copper requiring enzymes are dysfunction and cause multisystemic manifestations. The authors report a Thai boy 8 months of age who had depigmentation and kinky hair at birth. He developed myoclonic jerk at 3 months of age. He had hypopigmentation of the skin, delayed development, hypotonia, pectus excurvatum, loose skin and joints. He had anemia, very low serum copper and ceruloplasmin. X-ray showed Wormian bone of skull, osteopenia of long bones and generalized brain atrophy. The presented case has similar clinical and laboratory findings to 2 previous reports by Songkla University and Siriraj Hospital. Treatment is not effective due to unavailability of copper- histidinate and the patient already had severe brain damage. Genetic counseling is important to prevent the next offspring. Biochemical and molecular diagnosis are available for confirmation and prenatal diagnosis, but these techniques have limitations in Thailand. PMID:16858971

Coeliac disease causing symptomatic hypocalcaemia, osteomalacia and coagulapathy.  

PubMed

A 36-year-old gentleman presented with 6 months of poor energy, tingling in fingers and weight loss with a change in bowel habit. He appeared cachectic and had clubbing, demineralisation of teeth, pectus carinatus, kyphosis, spinal tenderness, proximal muscle weakness and generalised muscle atrophy. Chvostek's and Trosseau's signs were positive. His haemoglobin (Hb) was 8.7 g/dl, MCV 64.7 fl with low iron. Calcium corrected was 1.30 nmol/l, parathyroid hormone 440.4 ng/l, vitamin D <12.5 nmol/l; INR was 2.7 with coagulation inhibitor studies negative. Radiographs of spine and pelvis commented on osteopenia with thoracic kyphosis and mild anterior wedging of thoracic vertebrae. Antitissue transglutaminase was 145 U/ml, and antiendomysial antibodies were positive. An oesophagogastroduodenoscopy was consistent with coeliac disease. A diagnosis of osteomalacia and coagulopathy secondary to coeliac disease was made. The hypocalcaemia was treated with calcium gluconate infusions with symptomatic relief. Coagulopathy was treated with vitamin K intravenously with normalisation of INR. Following treatment with coeliac diet, calcium slowly normalised. PMID:22798310

An outbreak of Crimean-Congo hemorrhagic fever in the United Arab Emirates, 1994-1995.  

PubMed

A multi-faceted investigation was conducted in the United Arab Emirates to characterize the epidemiologic and ecologic factors underlying an outbreak of Crimean-Congo hemorrhagic fever (CCHF) noted in November 1994 among abattoir workers. A chart review was conducted among hospitalized suspected cases of viral hemorrhagic fever with onset between January 1994 and March 1995 coupled with serologic testing of available specimens for the presence of virus antigen and IgG and IgM antibodies by ELISA. Livestock handlers and animal skin processors were interviewed and tested for the presence of IgG antibody. Sera from imported and domestic ruminants were examined for antibody for CCHF virus, and ticks collected from these animals were tested with an antigen-capture ELISA. Thirty-five suspected cases of CCHF were identified (case fatality = 62%). Livestock market employees, abattoir workers, and animal skin processors accounted for 16 (57%) of 28 cases with known occupational status. Serologic evidence of past asymptomatic infection was noted in 12 (4%) of 291 livestock and abattoir workers but in none of the controls. Nineteen (7%) of 268 animals were positive for CCHF virus antibodies by ELISA including 12 ruminants from Somalia and Iran and five indigenous camels. One Hyalomma impeltatum and two H. excavatum from Somali cattle and one H. anatolicum from a Somali goat were positive for CCHF virus antigen. PMID:9392589

Preferences of different tick species for human hosts in Turkey.  

PubMed

The ticks removed from the patients who applied to the hospitals in Istanbul and neighboring cities, Turkey, with the complaint of tick bite were examined in this study, on account of their species, biological stages, attachment sites on the body, and the age of the affected patients. A total of 16,969 ticks were identified. Encountered species were as follows: 33.6 % Ixodes spp. immature, 25.3 % Hyalomma spp. immature, 24.3 % I. ricinus, 9.5 % Rhipicephalus sanguineus gr., 3.2 % R. bursa, 2.2 % Hyalomma marginatum, 1.96 % Haemaphysalis adults, 1.66 % Hyalomma aegyptium, 0.52 % Dermacentor marginatus, 0.39 % Rhipicephalus spp. nymphs, 0.12 % Dermacentor spp. nymphs, 0.11 % Haemaphysalis spp. nymphs, 0.09 % Hyalomma scupense, and 0.03 % Hyalomma excavatum. The distribution of attachment sites of the species and instars showed significant differences. Furthermore, age data of the patients also revealed that certain tick species were more common within certain age groups. PMID:23620419

Spotted fever group Rickettsiae in ticks in Cyprus.  

PubMed

In two surveys conducted from March 1999 to March 2001 and from January 2004 to December 2006, a total of 3,950 ticks (belonging to ten different species) were collected from seven domestic and wild animals (goat, sheep, cattle, dog, fox, hare, and mouflon) from different localities throughout Cyprus. In order to establish their infection rate with Spotted Fever Rickettsiae (SFG), ticks were pooled and tested by polymerase chain reaction targeting gltA and ompA genes, followed by sequencing analysis. When tick pools tested positive, individual ticks were then tested one by one, and of the 3,950 ticks screened, rickettsial DNA was identified in 315 ticks (infection rate, 8%). Five SFG Rickettsiae were identified: Rickettsia aeschlimannii in Hyalomma marginatum marginatum, Rickettsia massiliae in Rhipicephalus turanicus and Rhipicephalus sanguineus, Rickettsia sibirica mongolotimonae in Hyalomma anatolicum excavatum, and a Rickettsia endosymbiont of Haemaphysalis sulcata (later described as Rickettsia hoogstraalii) in Haemaphysalis punctata. Two additional genes, 17 kDa and ompB, were targeted to characterize a new genotype of "Candidatus Rickettsia barbariae" genotype in R. turanicus, designated here as "Candidatus Rickettsia barbariae" Cretocypriensis. These results confirm the presence of a spectrum of SFG Rickettsiae on the island. Further studies are necessary to gain better knowledge on the epidemiology of SFG Rickettsiae in Cyprus.

A molecular survey of Theileria and Babesia parasites in cattle, with a note on the distribution of ticks in Tunisia.  

PubMed

Between October and November 2006, a total of 278 bovine blood samples were examined, and 104 (37.4%) were positive for piroplasms by microscopy. A reverse line blot hybridisation with polymerase chain reaction detected Theileria annulata, T. buffeli, Babesia bovis and B. bigemina in cattle accounting for 48.6% of positive samples. The most frequently found species was T. buffeli, which was present in 39.2% of the samples. T. annulata was found in 48 samples (17.3%). Babesia infections were less frequently detected: B. bovis was found in 6.8% of the samples and B. bigemina in 4.3%. Mixed infections were detected in 45 samples, accounting for seven different combinations of species. Seven Ixodid tick species (Boophilus annulatus, Ixodes ricinus, Hyalomma marginatum, Hyalomma excavatum, Hyalomma detritum, Haemaphysalis punctata and Haemaphysalis sulcata) were collected from examined cattle in the 23 visited farms. I. ricinus was the dominant species (36%), mainly collected in the humid zone, while it seemed to be very rare in the semi-arid zone (where only 15 specimens were collected), whereas B. annulatus was the most commonly collected species in the sub-humid area (68.5% of ticks collected in this zone).

Tick-borne bacteria in mouflons and their ectoparasites in Cyprus.  

PubMed

The Cypriot mouflon (Ovis orientalis ophion), a once almost extirpated species of wild sheep, is under strict surveillance because it can be threatened by likely transmission of pathogenic bacteria, such as Anaplasma spp., Rickettsia spp., and Coxiella burnetii, primarily from domestic ungulates. We collected 77 blood samples from Cypriot mouflons and 663 of their ectoparasites (Rhipicephalus turanicus, Rhipicephalus sanguineus, Rhipicephalus bursa, Hyalomma anatolicum excavatum, Hyalomma marginatum, Haemaphysalis punctata, Haemaphysalis sulcata, and Ixodes gibossus) and tested them by polymerase chain reaction and sequencing. Twenty-three mouflon blood samples (30%) were positive for C. burnetii, 23 (30%) for Rickettsia spp., and 8 (10%) for Anaplasma ovis. Of 109 pools of ectoparasites, 32.1% were positive for C. burnetii, 28.4% for Rickettsia spp., and 10.9% for A. ovis; 11.9% were positive for both C. burnetii and Rickettsia spp., 6.4% for both Rickettsia spp. and A. ovis, and 2.8% for all three pathogens. This is the first survey that records the presence of tick-borne pathogens, both in the Cypriot mouflon and in ticks parasitizing it. PMID:21441182

Improved resolution of major clades within Tuber and taxonomy of species within the Tuber gibbosum complex.  

PubMed

Tuber gibbosum Harkn., described from northern California, originally was thought to be a single, variable species that fruited from autumn through winter to spring. It has become popular as a culinary truffle in northwestern USA, where it is commercially harvested. Morphological studies suggested it might be a complex that includes at least two species. We conducted morphological and phylogenetic studies of the complex to determine how many species it might contain and how they differed morphologically, geographically and seasonally. We also provide the first LSU phylogeny for the genus Tuber. Phylogenetic analyses resolve nine major clades in the genus with high bootstrap support and distinguish the Gibbosum clade from the Aestivum, Excavatum, Macrosporum, Magnatum, Melanosporum, Puberulum, Rufum and Spinoreticulatum clades. Further analyses of ITS and LSU regions revealed four distinct species in the Gibbosum complex. Although morphologically similar the four species differ in spore size and shape and in peridial anatomy. These species share the synapomorphy of having suprapellis hyphae with distinctive, irregular wall swellings at maturity; we have not seen this hyphal type in any other Tuber spp. worldwide. The three new species are named and described as T. bellisporum Bonito & Trappe, T. castellanoi Bonito & Trappe and T. oregonense Trappe, Bonito & Rawlinson. PMID:20943504

Foraminiferal biofacies analysis of the Yakataga Formation, Icy Bay, Alaska: Insights into Pliocene glaciomarine paleoenvironments of the Gulf of Alaska  

SciTech Connect

The Upper Miocene to Pleistocene Yakataga Formation of the Gulf of Alaska provides a 5 km thick record of episodic glacially-influenced marine sedimentation. The Pliocene Yakataga Fm. is exposed along western Icy Bay and records the return of glaciomarine deposition in the Gulf of Alaska, after the initiation of glaciation in the Late Miocene, and the onset of major northern hemisphere glaciation by the Late Pliocene. Analysis of foraminifera found in the Yakataga Fm. provides the basis for the interpretation of paleobathymetry and depositional environments from these rocks. Quantitative analysis is used to define eight paleoenvironmentally significant biofacies: (1) Elphidium excavatum clavatum biofacies (inner neritic), (2) Haplophragmoides spp. biofacies (outer neritic--mudline), (3) Cassidulina cf. C. teretis biofacies (outer neritic), (4) Uvigerina juncea biofacies (uppermost bathyal), (5) Elphidiella hannai biofacies (innermost neritic), (6) Epistominella pacifica biofacies (upper bathyal), (7) Cassidulina cf. C. limbata biofacies (outer neritic), (8) Nonionella miocenica biofacies (outer neritic). Paleobathymetric zones defined by these biofacies, which are constrained by modern Gulf of Alaska faunal relationships, indicate bathymetric fluctuations on the order of 100 m in the Icy Bay section. Mixing of biofacies due to downslope transport is common. Analyses of paleobathymetry, benthic formaminiferal biofacies, and sedimentology are used to interpret depositional environments ranging from innermost neritic to upper bathyal for these rocks.

Paleoenvironmental Change During the Holocene and Last Interglacial in San Pablo Bay, Northern California  

NASA Astrophysics Data System (ADS)

The San Francisco Bay exists as an estuary during sea level highstands and during this time its salinity field reflects the runoff regime of its watershed. Since the latter comprises about 40% of the state of California, study of the changing state of the estuary can provide insight into the climate history of the region. Previous studies have demonstrated significant secular variation in runoff during the late Holocene. The goals of the current work were to extend the record of the estuary's Holocene history and to investigate corresponding variation during the previous interglacial period (ca 130 - 115 ka). Changes at our study site indicative of variation in sediment budgets or tectonic activity were also of interest. Two boreholes were drilled along the southernmost margin of San Pablo Bay, a northern reach of San Francisco Bay. Estuarine sediments were examined for organic constituents; foraminifers were counted and shifts in species assemblages noted; their tests were subjected to stable isotope analysis so that variations in their isotopic signature could be tracked. Beneath recent fill and remnants of marsh deposits, each borehole showed a sequence of three stratigraphic units: Holocene bay mud; alluvial deposits; and estuarine mud. This stratigraphy resembles the typical south Bay sequence: Holocene mud; alluvium deposited during the last glacial period; estuarine mud deposited during the 5e highstand. Foraminifers recovered from the Holocene and older estuarine deposits support the correlation with south Bay deposits. On the basis of stratigraphic position and this correlation, we consider the older estuarine muds to date from the 5e highstand. Foraminiferal assemblages in both the Holocene and Last Interglacial sediments showed systematic variation indicative of environmental change at the site. The 5e samples document a shift in dominant species from Trochammina inflata in the lowermost sample to Elphidium gunteri in the middle of the section and to E. excavatum in the upper samples. This transition indicates a gradual change from shallow intertidal mudflat conditions to a subtidal environment, a shift similar to that indicated by the south Bay sediments. The Holocene interval shows two changes in dominant taxa. T. inflata predominates in the lowermost sample beneath a short non-estuarine interval. E. excavatum is dominant in the middle of the section but gives way abruptly to T. inflata in the upper samples. These shifts indicate sudden changes in water depth that produced rapid transitions from intertidal to subtidal and back to intertidal conditions at the site, likely a result of tectonic movements or changes in sediment input. Stable isotopic measurements of both foraminifers and mollusk shells are in progress. These results are expected to provide information about past salinity at this location, which reflects the volume of freshwater inflow to the estuary. Two 14C dates have been obtained on Holocene shell fragments. These samples, spaced 420 cm apart vertically, show (uncorrected) ages of 3545 and 1775 radiocarbon years, providing an estimated average accumulation rate at the site of about 2.4 mm/yr. If this rate applied throughout the Holocene at the site, the more recent shift noted above occurred about 2760 radiocarbon years (uncorrected for reservoir effect) ago, and the entire 12.8 m thick Holocene unit represents about a 5300 year record.

Safety and cardiovascular behavior during pulmonary function in patients with marfan syndrome.  

PubMed

Background: Marfan syndrome (MS) is a dominant autosomal connective tissue disease that impacts multiple systems, such as the cardiovascular system, tissue viscoelastic properties, bone calcification matrix and, most specific to the present investigation, pulmonary parenchyma. The aim of the present study was evaluate pulmonary function (PF) in patients with MS and relate it to thoracic cage abnormalities (TCA) and the occurrence of cardiac arrhythmias during the spirometric exam (SE). Method: A sample of 75 subjects (46 with MS) underwent clinical, anthropometric, echocardiographic, radiographic and PF evaluation; 51 subjects (33 with MS) had their ECG information evaluated during PF. These individuals were matched and compared to a healthy control group (CG) Results: Forced vital capacity (FVC) and forced expiratory volume in the first second (FEV(1) ) in the patients with MS were significantly lower in comparison to the CG (p=0.012 and p=0.0006) and predicted values (p=0.04 and p=0.003). Subgroup analysis based on TCA revealed differences between patients with MS with two combined abnormalities (scoliosis + pectus) in comparison to both the CG (p=0.012 and p=0.002) and patients without abnormalities (p=0.05 and p=0.006). There were no differences regarding the occurrence of arrhythmia during exertion on the SE. There was some correlation between clinical history and cardiovascular behavior and PF. Conclusion: PF is reduced in patients with MS and deformities in the thoracic cage appear to contribute to this reduction. Despite the apparent structural alterations in the cardiovascular system in this population, exertion during the spirometric exam appears to be safe. PMID:21204789

Identifying heritable connective tissue disorders in childhood.  

PubMed

Heritable connective tissue diseases are rare. Each disorder estimated at 1-10 per 100,000. However, as a group they are prevalent enough to constitute an important diagnostic challenge. Connective tissue disorders most significantly affect three systems: musculoskeletal, ocular and cardiovascular. The cardinal feature of the majority of these disorders is ligamentous laxity, or joint hypermobility. The joints show an increased range of movement, and the child may present with arthralgias, effusions and an increased risk of joint or soft tissue injury. Marfan syndrome is the most common heritable connective tissue disorder. It is an autosomal dominant condition with high penetrance but with striking pleiomorphism. In 25% of individuals there is no family history. The diagnosis is often not made until late childhood. Individuals are tall with a low upper: lower segment ratio and an arm span greater than height. Other skeletal characteristics include pectus deformity and scoliosis. Myopia and astigmatism are common. Cardiac abnormalities include mitral valve prolapse, mitral regurgitation and arrhythmias. Early diagnosis, meticulous echocardiographic follow-up and multidisciplinary assessment are essential. The Ehlers-Danlos syndromes share a triad of features: skin hyperextensibility, articular hypermobility, and tissue fragility. The abnormalities are caused by genetic defects resulting in the faulty synthesis or structure of collagen. There is a wide variety of phenotypes and mode of inheritance. Symptom management and joint protection are important to improve quality of life and prevent secondary complications. Osteogenesis imperfecta encompasses a group of rare heritable disorders associated with low bone mass and increased susceptibility to fractures. Increased bone fractures after minimal trauma is the cardinal feature. Other features include blue sclera, hearing loss, scoliosis, deafness, and hypermobility. PMID:22916581

PTPN11 Mutations in Noonan Syndrome: Molecular Spectrum, Genotype-Phenotype Correlation, and Phenotypic Heterogeneity  

PubMed Central

Noonan syndrome (NS) is a developmental disorder characterized by facial dysmorphia, short stature, cardiac defects, and skeletal malformations. We recently demonstrated that mutations in PTPN11, the gene encoding the non–receptor-type protein tyrosine phosphatase SHP-2 (src homology region 2-domain phosphatase–2), cause NS, accounting for ?50% of cases of this genetically heterogeneous disorder in a small cohort. All mutations were missense changes and clustered at the interacting portions of the amino-terminal src-homology 2 (N-SH2) and protein tyrosine phosphatase (PTP) domains. A gain of function was postulated as a mechanism for the disease. Here, we report the spectrum and distribution of PTPN11 mutations in a large, well-characterized cohort with NS. Mutations were found in 54 of 119 (45%) unrelated individuals with sporadic or familial NS. There was a significantly higher prevalence of mutations among familial cases than among sporadic ones. All defects were missense, and several were recurrent. The vast majority of mutations altered amino acid residues located in or around the interacting surfaces of the N-SH2 and PTP domains, but defects also affected residues in the C-SH2 domain, as well as in the peptide linking the N-SH2 and C-SH2 domains. Genotype-phenotype analysis revealed that pulmonic stenosis was more prevalent among the group of subjects with NS who had PTPN11 mutations than it was in the group without them (70.6% vs. 46.2%; P<.01), whereas hypertrophic cardiomyopathy was less prevalent among those with PTPN11 mutations (5.9% vs. 26.2%; P<.005). The prevalence of other congenital heart malformations, short stature, pectus deformity, cryptorchidism, and developmental delay did not differ between the two groups. A PTPN11 mutation was identified in a family inheriting Noonan-like/multiple giant-cell lesion syndrome, extending the phenotypic range of disease associated with this gene.

Clinical manifestations in 105 persons with nevoid basal cell carcinoma syndrome  

SciTech Connect

Nevoid basal cell carcinoma syndrome (NBCC; Gorlin syndrome), an autosomal dominant disorder linked to 9q22.3-q31, and caused by mutations in PTC, the human homologue of the Drosophila patched gene, comprises multiple basal cell carcinomas, keratocysts of the jaw, palmar/plantar pits, spine and rib anomalies and calcification of the falx cerebri. We reviewed the findings on 105 affected individuals examined at the NIH since 1985. The data included 48 males and 57 females ranging in age from 4 months to 87 years. Eighty percent of whites (71/90) and 38% (5/13) of African-Americans had at least one basal cell carcinoma (BCC), with the first tumor occurring at a mean age of 23 (median 20) years and 21 (median 20) years, respectively. Excluding individuals exposed to radiation therapy, the number of BCCs ranged from 1 to >1,000 (median 8) and 1 to 3 (median 2), respectively, in the 2 groups. Jaw cysts occurred in 78/105 (74%) with the first tumor occurring in 80% by the age of 20 years. The number of total jaw cysts ranged from 1 to 28 (median 3). Palmar pits and plantar pits were seen in 87%. Ovarian fibromas were diagnosed by ultrasound in 9/52 (17%) at a mean age of 30 years. Medulloblastoma occurred in 4 patients at a mean age of 2.3 years. Three patients had cleft lip or palate. Physical findings include {open_quotes}coarse face{close_quotes} in 54%, relative macrocephaly in 50%, hypertelorism in 42%, frontal bossing in 27%, pectus deformity in 13%, and Sprengel deformity in 11%. This study delineates the frequency of the clinical and radiological anomalies in NBCC in a large population of US patients and discusses guidelines for diagnosis and management. 48 refs., 3 figs., 5 tabs.

Species distribution and detection of Crimean Congo Hemorrhagic Fever Virus (CCHFV) in field-collected ticks in Ankara Province, Central Anatolia, Turkey.  

PubMed

Ticks may act as vectors for a number of infectious diseases including Crimean Congo Hemorrhagic Fever (CCHF). The causative agent is Crimean Congo Hemorrhagic Fever Virus (CCHFV), a member of Bunyaviridae, causing extensive ecchymosis, visceral bleeding and hepatic dysfunction with a high fatality rate in the affected individuals. CCHF was initially recognized in Turkey in 2002 and the current number of reported cases exceeds 4,400. This study was conducted to confirm the presence of tick species established as potential CCHFV vectors and investigate CCHFV activity in ticks at Ankara province, Turkey's second most-densely populated province, where CCHF cases were demonstrated. A total of 1,196 adult ticks, collected from various animals and vegetation in 12 sites located in 5 counties of Ankara during April-July 2010 were identified to species level. Twenty-two tick pools from county K2 were also evaluated for the presence of CCHFV RNA via a one-step real-time RT-PCR assay and reactive results were further confirmed by an in house nested RT-PCR assay. Nine tick species were identified: Rhipicephalus bursa (44.9%), R. sanguineus (18.9%), R. turanicus (18.1%), Haemaphysalis parva (8.3%), Hyalomma marginatum marginatum (5.4%), H. aegyptium (1.4%), H. anatolicum excavatum (1.3%), Hae. punctata (0.3%) and Dermacentor marginatus (0.2%). A total of five tick pools (22.7%) were reactive in real-time and nested RT-PCR assays. The pools included R. bursa, H. m. marginatum and Hae. parva ticks, collected from mammal hosts from two villages in one county. This is the first documentation of CCHFV activity in ticks from Ankara province, which indicates requirement for detailed surveillance to predict high risk zones in the region. PMID:21910017

Topical application of marine briarane-type diterpenes effectively inhibits 12-O-tetradecanoylphorbol-13-acetate-induced inflammation and dermatitis in murine skin  

PubMed Central

Background Skin is the largest organ in the body, and is directly exposed to extrinsic assaults. As such, the skin plays a central role in host defense and the cutaneous immune system is able to elicit specific local inflammatory and systemic immune responses against harmful stimuli. 12-O-tetradecanoylphorbol-13-acetate (TPA) can stimulate acute and chronic inflammation and tumor promotion in skin. TPA-induced dermatitis is thus a useful in vivo pharmacological platform for drug discovery. In this study, the inhibitory effect of briarane-type diterpenes (BrDs) from marine coral Briareum excavatum on TPA-induced dermatitis and dendritic cell (DC) function was explored. Methods Evans blue dye exudation was used to determine vascular permeability. H&E-stained skin section was used to determine the formation of edema in mouse abdominal skin. We also used immunohistochemistry staining and western blot assays to evaluate the activation of specific inflammation makers and key mediators of signaling pathway in the mouse skin. Furthermore, mouse bone marrow DCs were used to determine the relationship between the chemical structure of BrDs and their regulation of DC function. Results BrD1 remarkably suppressed TPA-induced vascular permeability and edema in skin. At the biochemical level, BrD1 inhibited TPA-induced expression of cyclooxygenase-2, inducible nitric oxide synthase and matrix metalloproteinase-9, the key indicators of cutaneous inflammation. This inhibition was apparently mediated by interference with the Akt/NF-?B-mediated signaling network. BrD1 also inhibited TNF-? and IL-6 expression in LPS-stimulated BMDCs. The 8, 17-epoxide of BrDs played a crucial role in the inhibition of IL-6 expression, and replacement of the C-12 hydroxyl group with longer esters in BrDs gradually decreased this inhibitory activity. Conclusions Our results suggest that BrDs warrant further investigation as natural immunomodulatory agents for control of inflammatory skin diseases.

Tracing latitudinal gradient, river discharge and water masses along the subtropical South American coast using benthic Foraminifera assemblages.  

PubMed

More than 30% of Buccella peruviana (D'Orbigny), Globocassidulina crassa porrecta (Earland & Heron-Allen), Cibicides mackannai (Galloway & Wissler) and C. refulgens (Montfort) indicate the presence of cold Sub Antarctic Shelf Water in winter, from 33.5 to 38.3º S, deeper than 100 m, in the southern part of the study area. In summer, the abundance of this association decreases to less than 15% around 37.5-38.9º S where two species (Globocassidulina subglobosa (Brady), Uvigerina peregrina (Cushman) take over. G. subglobosa, U. peregrina, and Hanzawaia boueana (D'Orbigny) are found at 27-33º S in both seasons in less than 55 m deep in the northern part, and are linked with warm Subtropical Shelf Water and Tropical Water. Freshwater influence was signalized by high silicate concentration and by the presence of Pseudononion atlanticum (Cushman), Bolivina striatula (Cushman), Buliminella elegantissima (D'Orbigny), Bulimina elongata (D'Orbigny), Elphidium excavatum (Terquem), E. poeyanum (D'Orbigny), Ammobaculites exiguus (Cushman & Brönnimann), Arenoparrella mexicana (Kornfeld), Gaudryina exillis (Cushman & Brönnimann), Textularia earlandi (Parker) and thecamoebians in four sectors of the shelf. The presence of Bulimina marginata (D'Orbigny) between 34.1-32.8º S in the winter and 34.2-32.7º S in the summer indicates that the influence of the Subtropical Shelf Front on the sediment does not change seasonally, otherwise, the presence of Angulogerina angulosa (Williamson) in the winter, only in Mar del Plata (38.9º S), show that Malvinas currents are not influencing the sediment in the summer.

The Early Geological History of Long Island Sound  

NASA Astrophysics Data System (ADS)

Long Island Sound (LIS), an urban estuary on the east coast of the USA, formed when terminal moraines created Long Island (NY) during the last glaciation. During early deglaciation, a periglacial lake developed behind this moraine (Glacial Lake Connecticut), which was rapidly filled with red, varved lake clays. Glacial Lake Connecticut drained when a barrier at its eastern end towards the Atlantic Ocean failed, at about 18 (calibrated) ka. The LIS basin then dried out, and a fluvial drainage pattern was carved into the lake beds (Lewis and Stone, 1991). With ongoing rise in global sea level, the sea entered LIS from the east and a marine-estuarine sediment sequence was deposited on the partially eroded varved clays. Lake Hitchcock formed behind the rapidly retreating Laurentide ice sheet in eastern New England, drained (possibly catastrophically) around 14 (calibrated) ka (Brigham-Grette, 2001), and created a coarse deltaic structure in LIS. Radiocarbon dates on bulk organic matter from the varved lake clays and marine silts indicate a time frame for Glacial Lake Connecticut between 18 and 16 ka, with the marine transgression possibly occurring around 15 ka (Lewis and DiGiacomo-Cohen, 2000). We dated organic carbon (hand picked terrestrial plant fragments) and mollusk fragments from core samples. Calibrated radiocarbon ages from organic material (ours and existing dates) do not show a clear relationship between age and depth-in-core. Radiocarbon dates show consistently older dates of organic matter than mollusk fragments from the same samples, with differences of up to 3000 years. We infer that the plant remains were stored on land for extensive periods of time before being deposited in LIS. The radiocarbon ages from mollusks show a curvi-linear relationship with depth, and suggest an age of about 10 (calibrated) ka for the marine transgression at the location of core LISAT 12 (in eastern LIS off the coast near Orient Point, Long Island). This new time frame suggests that the marine transgression occurred much later than thought, just after the Younger Dryas cold period and during Melt Water Pulse 1b of Fairbanks et al. (1989). Estimated rates of relative sea level rise from dated oyster beds (about 1.2 cm/yr) agree with the high rates indicated by these authors. This new timing of the flooding of the LIS basin poses the question whether Lake Hitchcock drained into Glacial Lake Connecticut rather than in marine waters. Preliminary stable isotope data on Elphidium excavatum from core LISAT 12 indicate that early LIS may have had slightly lower salinities than modern LIS, but foraminiferal faunas strongly resemble assemblages described from samples dated at 1000-1800 AD.

Impact of estrogen replacement therapy in a male with congenital aromatase deficiency caused by a novel mutation in the CYP19 gene.  

PubMed

Recent reports of the impact of estrogen receptor alpha and aromatase deficiency have shed new light on the importance of estrogen for bone formation in man. We describe a novel mutation of the CYP19 gene in a 27-yr-old homozygous male of consanguinous parents. A C to A substitution in intron V, at position -3 of the splicing acceptor site before exon VI of the CYP19 gene, is the likely cause of loss of aromatase activity. The mRNA of the patient leads to a frameshift and a premature stop codon 8 nucleotides downstream the end of exon V. Both parents were shown to be heterozygous for the same mutation. Apart from genua valga, kyphoscoliosis, and pectus carniatus, the physical examination was normal including secondary male characteristics with normal testicular size. To substitute for the deficiency, the patient was treated with 50 micro g transdermal estradiol twice weekly for 3 months, followed by 25 micro g twice weekly. After 6 months estrogen levels (<20 at baseline and 45 pg/ml at 6 months; normal range, 10-50) and estrone levels (17 and 34 ng/ml; normal range, 30-85) had normalized. Bone maturation progressed and the initially unfused carpal and phalangeal epiphyses began to close within 3 months and were almost completely closed after 6 months. The bone age, assessed by roentgenographic standards for bone development by Gruelich and Pyle, was 16.5 at baseline and 18-18.5 yr after 6 months of treatment. Bone density of the distal radius (left), assessed by quantitative computed tomography, increased from 52 to 83 mg/cm(3) (normal range, 120-160) and bone mineral density of the lumbar spine, assessed by dual-energy x-ray-absorptiometry, increased from 0.971 to 1.043 g/cm(2) (normal range, >1.150). Osteocalcin as a bone formation parameter increased from 13 to 52 micro g/l (normal range, 24-70) and aminoterminal collagen type I telopeptide as a bone resorption parameter increased from 62.9 to 92.4 nmol/mmol creatinine (normal range, 5-54). Semen analysis revealed oligoazoospermia (17.4 million/ml; normal >20) at baseline. After 3 months of treatment, the sperm count increased (23.1 million/ml) and decreased rapidly (1.1 million/ml) during the following 3 months. The sperm motility was reduced at baseline and decreased further during treatment. Area under the curve of insulin, C-peptide, and blood glucose levels during oral glucose tolerance test decreased after 6 months (insulin: 277 vs. 139 micro U/ml.h; C-peptide 52 vs. 15 ng/m.h; area under the curve glucose: 17316 vs. 12780 mg/d.min). Triglycerides (268 vs. 261 mmol/liter) and total cholesterol levels (176 vs. 198 mmol/liter) did not change significantly, but the low-density lipoprotein/high-density lipoprotein ratio decreased from 5.37 to 3.56 and lipoprotein (a) increased from 19.9 to 60.0 mg/dl (normal range, <30). In this rare incidence of estrogen deficiency, estrogen replacement demonstrated its importance for bone mineralization and maturation and glucose metabolism in a male carrying a novel mutation in the CYP19 gene.

Grupos españoles de cálculos ab initio de moléculas de interés astrofísico  

NASA Astrophysics Data System (ADS)

Pocos campos de la química están tan bien adaptados a la modelización por medio de los métodos teóricos de la Química Cuántica como la Astroquímica y la Química de la Atmósfera, donde las interacciones moleculares son, generalmente, lo suficientemente pequeñas para que el modelo de molécula aislada funcione muy bien. En España son varios los grupos teóricos que dedican su esfuerzo de investigación, o parte de él, al estudio de moléculas o procesos de interés en Astrofísica o en atmósferas planetarias. Presentaremos diferentes ejemplos paradigmáticos de esta actividad en la que se exploran desde aspectos estructurales, hasta aspectos espectroscópicos y dinámicos. Entre los últimos, cabe destacar estudios en los que se demuestra la importancia de procesos a dos estados, prohibidos por espín, en la formación astrofísica de diversos derivados de interés. En el tratamiento espectroscópico se han hecho esfuerzos interesantes, que han aunado teoría y experimento, en el estudio de sistemas relevantes desde el punto de vista atmosférico, como los hidratos de ácido nítrico, o el tratamiento espectroscópico de moléculas no rígidas. No menos interesantes son los estudios de fotoabsorción de radicales o de procesos multifotónicos. Son particularmente abundantes los estudios dedicados a la reactividad específica de sistemas de interés astrofísico o atmosférico, con el objetivo de esclarecer vías de formación de determinados compuestos o de proporcionar mecanismos que permitan identificar las etapas reactivas limitantes de reacciones de interés en esos medios y sobre los que no existía información previa. Así, por ejemplo, se han publicado interesantes estudios sobre la formación o propiedades de compuestos de fósforo, de silico o de azufre o sobre mecanismos de reacción en los que intervienen el ozono, el radical nitrato, el radical OH u otras especies. Finalmente, son también particularmente relevantes los estudios que varios grupos españoles han llevado, y siguen llevando a cabo, sobre sistemas débilmente enlazados, como complejos de Van der Waals o complejos por enlace de hidrógeno, que sin duda juegan un papel importante tanto en medios atmosféricos como interestelares.

Se encontró un riesgo mayor en individuos de 80 años y más (RR 2.44 IC 95%, 1.46–4.08), en los hombres (RR, 2.25 IC 95%, 1.46–3.49) y en sujetos con nivel educativo menor de 7 años. El estar bajo tratamiento con insulina incrementó el riesgo de demencia (RR, 2.83, IC 95%, 1.58–5.06). Las otras comorbilidades que aumentaron el riesgo de demencia en los pacientes diabéticos fueron la hipertensión (RR, 2.75, IC 95%, 1.86–4.06) y la depresión (RR, 3.78, 95% IC 2.37–6.04). Conclusión Los sujetos con diabetes mellitus tienen un riesgo mayor de desarrollar demencia, La baja escolaridad y otras comorbilidades altamente prevalentes en la población Mexicana contribuyen a la asociación diabetes-demencia.

Use of black vulture (Coragyps atratus) in complementary and alternative therapies for cancer in Colombia: A qualitative study  

PubMed Central

Background Although Coragyps atratus has been used as a traditional therapy for patients with cancer, the scientific literature does not contain enough information on how this therapy is used or the mechanisms that explain this therapeutic practice. Objectives To understand the methods of use and the reasons given by patients and caregivers for the use of Coragyps atratus in cancer treatment. Methods This study used a qualitative design based on twenty in-depth interviews of patients with cancer or caregivers of patients with the disease. The analysis of the text was based on an inductive thematic approach. Results Resistance to disease and immune enhancement are properties attributed to Coragyps atratus when used for cancer treatment. The most recommended method of use is fresh blood ingestion, and the associated mechanism of action is transfer of immune factors to the individual who consumes it. Conclusions Use of Coragyps atratus as a treatment for cancer is a popular alternative therapy in Colombia. More studies are needed to understand the clinical effects of this intervention in cancer patients. Spanish abstract Introducción Aunque Coragyps atratus se usa tradicionalmente como terapia para pacientes con cáncer, no existe suficiente información en la literatura científica sobre su forma de utilización ni sobre los mecanismos explicativos que subyacen a esta práctica terapéutica. Objetivos Conocer métodos de utilización y mecanismos explicativos dados por los pacientes y cuidadores de pacientes sobre el uso de Coragyps atratus en el tratamiento del cáncer. Materiales y métodos Diseño cualitativo basado en veinte entrevistas en profundidad de pacientes con cáncer o cuidadores de pacientes con esta enfermedad. Análisis de texto basado en enfoque temático inductivo. Resultados Al Coragyps atratus se le atribuyen propiedades de resistencia y fortalecimiento del sistema inmune de personas enfermas de cáncer. La forma de utilización mas común es la ingesta de la sangre fresca y el mecanismo de acción asociado es la transferencia de defensas a quien lo consume. Conclusiones La utilización del Coragyps atratus como tratamiento para el cáncer es una terapia alternativa usada popularmente en Colombia. El uso de este animal debe estudiarse más a fondo para conocer los efectos clínicos en los pacientes con cáncer.

Risk-adapted treatment for low- and intermediate-risk acute promyelocytic leukemia.  

PubMed

The clinical integration of risk-tailored therapies for patients with acute promyelocytic leukemia (APL) has become a standard treatment approach in recent years. In this article, we will review the risk-adapted strategies designed to treat patients with white blood cell counts ? 10 × 109/L, with platelet counts > 40 × 109/L (low risk), or platelet counts ? 40 × 109/L (intermediate risk), with particular reference to the risk-adapted strategy followed in the LPA99 and LPA2005 trials conducted by the Programa para el Tratamiento de Hemopatías Malignas group. In these studies, the combination of all-trans-retinoic acid (ATRA) and chemotherapy in consolidation therapy resulted in an improved antileukemic efficacy without significantly increasing toxicity in low-risk (LPA2005 trial vs. LPA99 trial) and intermediate-risk (LPA99 trial vs. LPA96 trial) categories. In addition, a decrease in dose intensity of mitoxantrone in low- and intermediate-risk patients (LPA2005 trial vs. LPA99) resulted in a significant reduction of hematologic toxicities and hospital stay without compromising antileukemic activity. We will also discuss whether the use of arsenic trioxide to reinforce consolidation therapy in standard ATRA/chemotherapy regimens can permit a reduction of chemotherapy intensity while maintaining cure rates or confirm the improvement on outcomes currently achieved with optimal ATRA/anthracycline-based protocols.

Lessons from scaling up a depression treatment program in primary care in Chile.  

PubMed

In Chile, the National Depression Detection and Treatment Program (Programa Nacional de Diagnóstico y Tratamiento de la Depresión, PNDTD) in primary care is a rare example of an evidence-based mental health program that was scaled up to the national level in a low- or middle-income country. This retrospective qualitative study aimed to better understand how policymakers made the decision to scale up mental health services to the national level, and to explore the elements, contexts, and processes that facilitated the decision to implement and sustain PNDTD. In-depth semistructured interviews with six key informants selected through intentional sampling were conducted in August-December 2008. Interviewees were senior officers at the Ministry of Health who were directly involved in the decision to scale up the program. Results yielded four elements pivotal to the decisionmaking process: scientific evidence, teamwork and leadership, strategic alliances, and program institutionalization. Each element contributed to building consensus, securing funding, attracting resources, and gaining lasting support from policymakers. Additionally, a review of available documentation led the authors to consider sociopolitical context and use of the media to be important factors. While research evidence for the effectiveness of mental health services in the primary care setting continues to accumulate, low- and middle-income countries should get started on the lengthy process of scaling up by incorporating the elements that led to decisionmaking and implementation of the PNDTD in Chile.

Sobre el estado evolutivo de ? Pictoris  

NASA Astrophysics Data System (ADS)

Desde el descubrimiento de fuertes excesos infrarrojos en ? Pictoris, esta estrella ha sido muy estudiada y es considerada candidata a poseer un sistema planetario propio. ? Pic está rodeada de un disco asimétrico de polvo que se observa de canto y que esta vacío a distancias <= 40 AU. Esto se considera una fuerte evidencia en favor de la presencia de (al menos) un planeta gigante. Recientemente se han observado líneas de material circunestelar que se han interpretado como consecuencia de la caída de objetos cometarios sobre esta estrella. Recientemente se ha utilizado la existencia del disco de polvo para atribuir una edad corta (pre - secuencia principal) a ?Pic. Sin embargo, la evaporación de estos cometas provee suficiente polvo como para explicar la presencia del disco observado sin necesidad de edades cortas. En este trabajo mostramos que la comparación entre la tasa de impactos cometarios estimada en el Sistema Solar para diferentes etapas de su evolución y los datos observados en ? Pic indica edades avanzadas para ? Pic. Esta estimación debe tomarse con cautela ya que depende de la estructura de los sistemas planetarios. Además mostramos que, desde el punto de vista de la evolución estelar y con las incertezas presentes en la luminosidad y la temperatura efectiva, existe un continuo de edades posible para ? Pic. Sin embargo, empleando los datos provenientes de los flujos cometarios encontramos que una edad prolongada es consistente con ambos tratamientos.

Esquizofrenia y trastorno en el consumo de sustancias: prevalencia y character?sticas sociodemogr?ficas en la poblaci?n Latina  

PubMed Central

El interés por comprender la co-morbilidad de la esquizofrenia y el trastorno en el uso de sustancias, ha aumentado debido al incremento de este diagnóstico, a los efectos negativos observados en el sujeto y a los costos en los servicios de salud. Este trastorno dual puede tener efectos dramáticos en el curso clínico del trastorno psicótico tales como: mayores recaídas, re-hospitalizaciones, síntomas más severos, no adherencia al tratamiento antipsicótico, cambios marcados del humor, aumento en el grado de hostilidad e ideación suicida, así como alteraciones en otras áreas del funcionamiento incluyendo violencia, victimización, indigencia y problemas legales. La literatura proveniente en particular de Estados Unidos y Europa sugiere que el rango de prevalencia para este diagnóstico puede oscilar entre el 10% hasta el 70%. En este estudio, revisamos la prevalencia del diagnóstico dual de esquizofrenia y trastorno en el uso sustancias, así como sus características sociodemográficas, con base en la literatura disponible alrededor del mundo dando énfasis en la poblacion latina. A pesar de que este diagnóstico es ampliamente aceptado, se conoce poco sobre su prevalencia en la población latina, sobre los factores ambientales, demográficos, clínicos y otras características de estos individuos. Un mejor conocimiento sobre este diagnóstico permitiría mejorar los métodos para la detección y adecuada valoración del trastorno en el uso de sustancias en personas con trastornos metales severos como la esquizofrenia.

Prognostic value of FLT3 mutations in patients with acute promyelocytic leukemia treated with all-trans retinoic acid and anthracycline monochemotherapy  

PubMed Central

Background Fms-like tyrosine kinase-3 (FLT3) gene mutations are frequent in acute promyelocytic leukemia but their prognostic value is not well established. Design and Methods We evaluated FLT3-internal tandem duplication and FLT3-D835 mutations in patients treated with all-trans retinoic acid and anthracycline-based chemotherapy enrolled in two subsequent trials of the Programa de Estudio y Tratamiento de las Hemopatías Malignas (PETHEMA) and Hemato-Oncologie voor Volwassenen Nederland (HOVON) groups between 1996 and 2005. Results FLT3-internal tandem duplication and FLT3-D835 mutation status was available for 306 (41%) and 213 (29%) patients, respectively. Sixty-eight (22%) and 20 (9%) patients had internal tandem duplication and D835 mutations, respectively. Internal tandem duplication was correlated with higher white blood cell and blast counts, lactate dehydrogenase, relapse-risk score, fever, hemorrhage, coagulopathy, BCR3 isoform, M3 variant subtype, and expression of CD2, CD34, human leukocyte antigen-DR, and CD11b surface antigens. The FLT3-D835 mutation was not significantly associated with any clinical or biological characteristic. Univariate analysis showed higher relapse and lower survival rates in patients with a FLT3-internal tandem duplication, while no impact was observed in relation to FLT3-D835. The prognostic value of the FLT3-internal tandem duplication was not retained in the multivariate analysis. Conclusions FLT3-internal tandem duplication mutations are associated with several hematologic features in acute promyelocytic leukemia, in particular with high white blood cell counts, but we were unable to demonstrate an independent prognostic value in patients with acute promyelocytic leukemia treated with all-trans retinoic acid and anthracycline-based regimens.

Absence of beta-amyloid in cortical cataracts of donors with and without Alzheimer's disease.  

PubMed

Eye lenses from human donors with and without Alzheimer's disease (AD) were studied to evaluate the presence of amyloid in cortical cataract. We obtained 39 lenses from 21 postmortem donors with AD and 15 lenses from age-matched controls provided by the Banco de Ojos para Tratamientos de la Ceguera (Barcelona, Spain). For 17 donors, AD was clinically diagnosed by general physicians and for 4 donors the AD diagnosis was neuropathologically confirmed. Of the 21 donors with AD, 6 had pronounced bilateral cortical lens opacities and 15 only minor or no cortical opacities. As controls, 7 donors with pronounced cortical opacities and 8 donors with almost transparent lenses were selected. All lenses were photographed in a dark field stereomicroscope. Histological sections were analyzed using a standard and a more sensitive Congo red protocol, thioflavin staining and beta-amyloid immunohistochemistry. Brain tissue from two donors, one with cerebral amyloid angiopathy and another with advanced AD-related changes and one cornea with lattice dystrophy were used as positive controls for the staining techniques. Thioflavin, standard and modified Congo red staining were positive in the control brain tissues and in the dystrophic cornea. Beta-amyloid immunohistochemistry was positive in the brain tissues but not in the cornea sample. Lenses from control and AD donors were, without exception, negative after Congo red, thioflavin, and beta-amyloid immunohistochemical staining. The results of the positive control tissues correspond well with known observations in AD, amyloid angiopathy and corneas with lattice dystrophy. The absence of staining in AD and control lenses with the techniques employed lead us to conclude that there is no beta-amyloid in lenses from donors with AD or in control cortical cataracts. The inconsistency with previous studies of Goldstein et al. (2003) and Moncaster et al. (2010), both of which demonstrated positive Congo red, thioflavin, and beta-amyloid immunohistochemical staining in AD and Down syndrome lenses, is discussed. PMID:23142516

Progress in the prognosis of adult Hodgkin's lymphoma in the past 35 years through clinical trials in Argentina: a GATLA experience.  

PubMed

The purpose of this study was to evaluate the trends in complete remission (CR) rate, disease-free survival (DFS), and overall survival (OS) through 35 years of Grupo Argentino de Tratamiento de la Leucemia Aguda (GATLA) clinical trials. A total of 1,254 adult patients with Hodgkin's Lymphoma were evaluated according to seven consecutive protocols. This 35-year study was divided into three phases. The patients in the first phase (1968-1985) were treated with CVPP (cyclophosphamide/vinblastine/procarbazine/prednisone) plus involved-field radiotherapy (IFRT). In the CVPP regimen, cyclophosphamide and vinblastine were administered intravenously on day 1 and prednisone and procarbazine were administered orally on days 1-14 every 28 days. The second phase (1986-1996) used mainly reinforced CVPP with cyclophosphamide and vinblastine on days 1-8 plus IFRT. The third phase (1997-2003) used ABVD(doxorubicin/bleomycin/vinblastine/dacarbazine) plus IFRT. In clinical stage I/II, the CR rate was 86% in 252 patients treated in the first phase and DFS and OS were 57% and 78% at 5 years and 50% and 71% at 10 years. The second phase had 148 patients with clinical stage I/II disease, and the CR rate was 91%, 5-year DFS and OS were 78% and 90%, and 10-year DFS and OS were 70% and 83%. The third phase had 182 patients with clinical stage I/II disease, and the CR rate was 95%, 5-year DFS and OS were 87% and 96%, and 10-year DFS and OS were not reached. The statistical difference was P = 0.016 in terms of CR and P < 0.001 in terms of DFS and OS. In the first phase of 394 patients with clinical stage III/IV disease, the CR rate was 71%, DFS and OS at 5 years were 37% and 62%, and DFS and OS at 10 years were 32% and 53%. In the second phase of 164 patients with clinical stage III/IV disease, the CR rate was 84%, DFS and OS at 5 years were 66% and 80%, and DFS and OS at 10 years were 60% and 75%. In the third phase of 114 patients with clinical stage III/IV disease, the CR rate was 88% and DFS and OS at 5 years were 60% and 90%. The DFS and OS were not reached at 10 years. The differences among the 3 phases in CR, DFS and OS were highly significant (P < 0.001). PMID:15453925

Effect of acclimation to outdoor condition on the sexual performance of mass-produced Medflies (Diptera: Tephritidae)  

SciTech Connect

Application of the sterile insect technique (SIT) as part of integrated area-wide programs to control the Mediterranean fruit fly (medfly) Ceratitis capitata (Wiedemann) require that the released males attract wild females and transfer sterile sperm. However, knowledge about male sexual performance after they are released is scarce. We conducted a study to evaluate male sexual performance in field cage tests, according to standard quality control procedures. Mass-reared 5-d-old sterile males from the genetic sexing strain VIENNA 7mix2000 were acclimated for 0, 1, and 3 d to outdoor conditions before competing with wild males for wild females. Although the proportion of mating (PM) in the test was satisfactory, the resulting relative sterility index (RSI) data showed no significant differences among the treatments. The data indicate that pre-conditioning males to outdoor conditions in Madeira did not confer an advantage in field cage sexual performance. (author) [Spanish] La aplicacion de la tecnica del insecto esteril (TIE) como parte de un programa integrado de amplio efecto para el control de la mosca mediterranea de la fruta Ceratitis capitata (Wiedemann) requiere que los machos liberados atraigan las hembras naturales y transfieran su esperma. Sin embargo, el conocimiento del desempeno sexual de los machos despues de ser liberados es muy escaso. Nosotros realizamos un estudio para evaluar el desempeno sexual de los machos en pruebas usando jaulas del campo, segun los procedimientos estandardizados de calidad. Machos esteriles de 5 dias de edad de la raza que separa los sexos geneticamente VIENNA 7mix2000 criados en masa fueron aclimatados por 0, 1 y 3 dias en condiciones de campo antes de competir con machos naturales para las hembras naturales. Aunque la proporcion del apareamiento en la prueba fue satisfactorio, el indice relativo de esterilidad (IRS) resultante no mostro ninguna diferencia significativa entre los tratamientos. Los datos indicaron que al condicionar los machos anteriormente a las condiciones de campo en Madeira no conferio ventaja alguna en el desempeno sexual en la jaula de campo. (author)

The effects of training in time-limited dynamic psychotherapy: changes in therapeutic outcome.  

PubMed

The present study explored the effects on therapeutic outcomes of training therapists in brief manualized therapy. As part of the Vanderbilt II project, each of 16 therapists (8 psychiatrists and 8 clinical psychologists) treated 2 moderately disturbed adult patients using his or her customary short-term treatment methods; they then received a year of training in a manualized form of brief dynamic therapy, Time-Limited Dynamic Psychotherapy (TLDP); finally, they administered TLDP to 2 additional patients. It was hypothesized that training would result in improved outcomes generally and that differentially greater improvement would be seen in patients commonly considered less suitable for brief dynamic therapy. Outcome data obtained at termination failed to support either hypothesis. Measurements of interpersonal dependency obtained at a one-year follow-up were consistent with the first hypothesis, but the follow-up data were inconsistent with the second. A systematic review of the 32 posttraining cases suggested that the majority of the therapists had not achieved basic competence at TLDP. Die hier beschriebene Studie untersucht die Wirkungen eines Trainings in manualisierter Kurzzeitherapie auf das Therapierergebnis. Als Teil des Vanderbilt II Projektes behandelten jeweils 16 Therapeuten (8 Psychiater und 8 klinische Psychologen) zwei mittelgradig beeinrächtigte erwachsene Patienten mit den ihnen vertrauten Kurzzeitbehandlungsmethoden. Danach wurden sie über ein Jahr in einer manualisierten Form psychodynamischer Kurzzeittherapie ausgebildet und wandten diese Therapie auf zwei weitere Patienten an. Es wurde angenommen, dass die Ausbildung in besseren Ergebnisdaten, die bei Ende der Therapie erhoben wurden, konnten diese Hypothese nicht bestätigen. Maße für die interpersonale Abhängigkeit zu einem Einjahreskatamnesezeitpunkt waren mit der ersten Hypothese konform, aber inkonsistent mit der zweiten. Eine systematische Untersuchung der 32 nach der Ausbildung behandelten Fälle legt nahe, dass die Mehrzahl der Therapeuten keine grundlegende Kompetenz in zeitlich limitierter dynamischer Psychotherapie erworben hatte. Cette éude explore les effets sur les résultats thérapeutiques de la formation des thérapeutes dans une thérapie brève, manualissée. Dans le cadre du projet Vanderbilt II, chacun des 16 thérapeutes (8 psychiatrs et 8 psychologues cliniciens) a traité deux patients adultes modérément perturbés, chacun par sa méthode habituelle de thérapie brève; ensuite ils ont reçu une formation d'une année dans une méthode manualisée de thérapie brève, la Psychothérapie Dynamique Limitée dans le Temps (TLDP); pour finir, ils ont appliqué la TLDP à de meilleurs résultats en général, et qu'une amélioration comparativement plus importante sera observée chez des patients habituellement considérés comme moins adaptés à une thérapie dynamique brè. Les résultats obtenus à la terminaison n'ont pu confirmer aucune de ces hypothèses. Des mesures de la dépendance interpersonnelle une année après étaient consistantes avec la première hypothèse, mais les données catamnestiques étaient inconsistantes avec la deuxième. Une revue systématique des 32 cas après formation a suggéré que la majorité des thérapeutes n'avait pas acquis une compétence de base en TLDP. Este estudio exploró la efectividad del entrenamiento de terapeutas en una terapia breve manualizada. Como parte del proyecto Vanderbilt II, dieciséis terapeutas (ocho psiquiatras y ocho psicólogos clínicos) trataron dos pacientes adultos mooderadamente perturbados con sus métodos habituales de tratamiento a corto plazo. Estos terapeutas recibieron luego un año de entrenamiento en terapia dinámica breve manualizada que se Ilamó Psicoterapia Dinámica de Tiempo limitado (TLDP). Finalmente, administraron esta TLDP a dos pacientes más. La hipótesis fue que el entrenamiento ilevaría, en general, a resultados mejores y que habría mayor mejoramiento en pacientes menos aptos para una terapia dinámica breve. Los resultados

Impact of Chloroquine on Viral Load in Breast Milk  

PubMed Central

Summary The anti-malarial agent chloroquine has activity against HIV. We compared the effect of chloroquine (n = 18) to an anti-malarial agent without known anti-HIV-activity, sulfadoxine-pyrimethamine (n = 12), on breast milk HIV RNA levels among HIV-infected breastfeeding women in Zambia. After adjusting for CD4 count and plasma viral load, chloroquine was associated with a trend towards lower levels of HIV RNA in breast milk compared with sulfadoxine-pyrimethamine (P 0.05). Higher breastmilk viral load was also observed among women receiving presumptive treatment = for symptomatic malaria compared with asymptomatic controls and among controls reporting fever in the prior week. Further research is needed to determine the potential role of chloroquine in prevention of HIV transmission through breastfeeding. Impacte de la chloroquine sur la charge virale dans le lait maternelle La chloroquine, agent antimalarique, a une activité contre le VIH. Nous avons comparé l’effet de la chloroquine à celui d’un autre agent antimalarique, la sulfadoxine-pyrimethamine, dont l’activité sur le VIH n’est pas connue, en mesurant les taux d’ARN de VIH dans le lait maternel de femmes allaitantes infectées par le VIH en Zambie. Après ajustement pour les taux de CD4 et la charge virale dans le plasma, la chloroquine comparée à la sulfadoxine pyrimethamine était associée à une tendance vers des teneurs plus bas en ARN de VIH dans le lait maternel (P = 0,05). Des charges virales plus élevées dans le lait maternel étaient aussi observées chez des femmes recevant un traitement présomptif pour des symptômes de malaria par rapport aux contrôles asymptomatiques et par rapport à des contrôles rapportant de la fièvre durant la première semaine. Des études supplémentaires sont nécessaires pour déterminer le rôle potentiel de la chloroquine dans la prévention de la transmission du VIH par l’allaitement maternel. mots clésVIH, malaria, allaitement maternel, chloroquine, sulfadoxine-pyrimethamine, charge virale du lait maternel, fièvre Impacto de la cloroquina en la carga viral de la leche materna El antimalárico cloroquina tiene actividad frente al VIH.

Después de ajustar para recuento de CD4 y la carga viral en plasma, se asoció a la cloroquina con una tendencia hacia menores niveles de ARN del VIH en leche materna, comparado con la sulfadoxina pirimetamina (P = 0.05). También se observó una mayor carga viral en la leche materna de mujeres recibiendo tratamiento presuntivo para malaria sintomática, que en los controles asintomáticos y controles que habáan reportado fiebre la semana anterior. Es necesario realizar más estudios para determinar el papel potencial de la cloroquina en la prevención de la trasmisión de VIH a través de la lactancia materna. palabras claveVIH, malaria, lactancia materna, cloroquina, sulfadoxina pirimetamina, transmisión vertical, leche materna, carga viral, fiebre
