Prof. H Michael Dosch received all his schooling & training in, then, West Germany, graduating with the German MD, PhD degree in 1970 from Phillips University in Marburg/rnLahn. In 1974 he began postdoctoral training at Toronto University, Canada, joined the Faculty 1977 and was promoted to full Professor of Pediatrics and Immunology. Hisrncore interest molecular & cellular elements of (mostly) Type-1 Diabetes documented in over 500 often high profile articles.
Our Diabetes Research Program focused on neuronal elements in T1D pathogenesis. We found that in T1D mouse models as wellrnas patients, 1.) a major subset of autoimmune targets have neuronal derivation; 2.) TRPV1 (transient receptor potential, vanilloid-rn1, a Ca++channel) mutations are a core disease-prerequisite, which consequent deficiency of TRPV1-dependent neuropeptidesrnsuch as substance P (sP). Hypofunctional/hyposecretory mutations in T1D-prone NOD mice have analogs in T1D patients: humanrnTRPV1 (chromosome 17) is polymorphic with possibly thousands of varied alleles, but we found the exclusive presence of the same,rn4 alleles in over 50 patients. Th e sole exception was one T1D patient, carrying non-polymorphic, African TRPV1. Single nucleotidernpolymorphisms (SNP) Analysis of 1000-Genomes data showed 59 severe SNP mutations TRPV1(2.3%). Remarkably, there were 159rnTRPV1 SNPs in our fi rst 21 T1D patients, clustered mainly in 6 of 28 genomic PCR fragments sequenced, and this trend is sustainedrnin 28 additional patients. Collectively, these data emphasize similarities between NOD mice and patients, with TRPV1 clearly arnprominent if not the major element. T1D is reversed in NOD mice for months following a single pancreatic sP injection via the celiacrnartery, a routine medical access route in Interventional Image-Guided therapies (IGT). Recently, substantial reserves of pre-betacellsrnwith re-diff erentiation of functionality were discovered well aft er T1D onset. Here we describe our approved translational trial,redesigned to determine if and at what doses can reverse human T1D.

Vascular malformations are most frequent located in the maxillofacial area. It is important that a proper diagnosis is made, asrnthe treatment is diff erent for the diff erent types of vascular lesions. Arteriovenous Malformations and A-V fistulae, are high fl owrnlesions, with a reddish discoloration, the temperature over the area is increased, with prominent pulsations, a thrill and a bruit mayrnbe present. Th ere will be mass effect, compression of vital structures, pain and hemorrhage. It is the most difficult type to treat, and itrnis the most aggressive in presentation. Venous Malformations are slow flow lesions, and the most frequent type of vascular birthmark.rnFrequently multifocal. Symptoms depend on the location, mass effect, cosmetic and functional manifestations, discomfort and pain. The skin over the area is of normal temperature with bluish discoloration, there easily compressible, none pulsatile and they willrnexpand with Valsalva maneuvers. Lymphatic Malformations are very low fl ow collections of lymphatic fluid. They present as noncompressiblernmass lesions with contour deformities, compression of vital structures may occur. The skin is of normal temperature, rnnonpulsatile. Th ey may be macrocystic or microcystic, or mixed. Hemangiomas are proliferative tumors of infancy they appearsrnshortly aft er birth and will go through a rapid growth cycle the proliferative phase, reach her maximum within months or severalrnyears and then spontaneously involute. We will present the various endovascular techniques, including transarterial embolization,rnpercutaneous embolization, sclerotherapy, combination treatments.

Laura Odom recently completed her DNP from Vanderbilt University after practicing in an Allergy/Immunology clinic as a Family Nurse Practitioner for the last twelve years. She is a clinical assistant professor at the University of Tennessee, Knoxville and is the Presdient and Co-founder of Medic Apps, LLC. She has filed a provisonal patent and trademark for her asthma action plan application BreatheEasy. She is an allied health member of the AAAAI, and is a member of the Adverse Reactions to Foods Committee and the Asthma, Cough, Diagnosis and Treatment Committee.
Background: Asthma burden affects mortality, morbidity, quality of life, and the economy. The British Medical Journal recently reported that two-thirds of asthma deaths are due to failure to follow recommended guidelines and primary care failings in routine care. Written asthma action plans are standard of care according to national guidelines, but these plans are seldom prescribed. Furthermore, these written care plans are often unavailable at the time of an exacerbation. The purpose of this project was to create an asthma action plan application for smartphones. The goal of the project was improved patient access to their asthma action plan and improved utilization rates among providers. Methods: A development studio was consulted for support in developing a smartphone application to code the software for the asthma action plan and assist in the design process. Following development of the application, a survey was completed to evaluate design and functionality. Results: All survey participants agreed that the application was easy to use, could be used without written instruction and was designed for adolescents with asthma of any severity. Patients and providers noted that the app would help provide information about what to do in the event of an asthma exacerbation and that the application would be used frequently. Conclusions: There was consensus from both patients and providers that this application is not only functional but also helpful in the event of an asthma exacerbation. The project met the goal of creating a mobile phone application that improved patient access to asthma action plans.

She served as Faculty member in Stanford, before moving to Monroe Carell Jr. Children’s Hospital at Vanderbilt University, where she currently holds a position as Assistant Professor and is primarily involved in Pediatric Cardiac Anesthesia. She obtained various research awards, has published in high-ranked peer reviewed journals and co-authored several book chapters in major anesthesia textbooks. Her research interests include basic and clinical neurosciences, with the current focus on neuromonitoring and neurocognitive outcome in pediatric cardiac surgical patients. She is presently involved in clinical research, serving as PI or Co-PI on several different studies.
Congenital heart disease (CHD) is the most common birth defect. Today, an increasing number of affected children, who not long ago were considered “inoperable” are now living into adulthood. In fact, there are now more adults than children living with CHD. This turning point has shifted the focus from “primarily survival” to “improving quality of life” for these patients. For this matter, a major area of concern is neurological morbidity, that affects 30-50% of children with CHD and is attributable to multiple causes. While vital organs are routinely monitored in the pediatric cardiac surgical setting, this typically does not hold true for the brain, where monitoring is still indirect. Yet, reliable and accurate neurological monitoring is essential to reduce the incidence of neurological complications and subsequent potential long-term cognitive dysfunction. In this discussion, we review various modalities of neuromonitoring for children undergoing congenital heart surgery with a focus on Near-Infrared Spectroscopy (NIRS). In addition, our own data will be presented, investigating a next generation NIRS device (FORE-SIGHT Elite Tissue oximeter) in combination with simultaneous vital sign recording in pediatric patients undergoing cardiac catheterization. Our data suggest that NIRS monitoring appears superior to standard vital sign monitoring when assessing “brain well-being”, thereby supporting routine use of NIRS as an independent monitor to achieve safer peri-OP management in this vulnerable and extremely heterogeneous patient population. Clearly, future studies refining efficacy and application of this technology are warranted and are on the way.

The aim of this paper is to remind to general pediatricians the risk of viral myocarditis as a part of a common viral infection. To explain the clinical futures, the diagnostic algorithm and the available treatments in primary and in hospital care Myocarditis is an inflammatory disease of heart muscle and the pericardium. It is an important cause of dilated cardiomyopathy worldwide. Viral infections are the commonest cause of myocarditis. The spectrum of viruses known to cause myocarditis has changed in the past 2decades. Several new diagnostic methods, such as cardiac MRI, are useful for diagnosing myocarditis. Endomyocardial biopsy may be used for patients with acute dilated cardiomyopathy associated with hemodynamic compromise, those with life-threatening arrhythmia, and those whose condition does not respond to conventional supportive therapy, to differentiate dilated cardiomyopathy from acute myocarditis. Important prognostic variables include the degree of LV and RV dysfunction, heart block, and specific histopathological forms of myocarditis. We review diagnostic and therapeutic strategies of viral myocarditis

Title: Heliox as adjunctive therapy to treat rhinovirus/enterovirus infection related respiratory failure in infants and children – A case review
Time : 11:50-12:15
S E Morgan is a Registered Respiratory Therapist and an Advanced Respiratory Care Practitioner with the National Board for Respiratory Care. He is an active member of The America Association for Respiratory Care. He serves as Clinical Practice and Development /Educator/ Research Coordinator for the Department of Respiratory Care Services, Section of Pulmonary and Critical Care Medicine at the UCM. He has published more than 30 peer review papers regarding subjects such as; nitric oxide, heliox, infl uenza-related respiratory disease and aerosolized epoprostenol) in different medical journals. He has collaborated with departments of neonatology and pediatrics on respiratory related research projects.
Infl uenza-like respiratory infections is a frequent trigger for status asthmaticus. Helium-oxygen (heliox) gas mixtures, has been used for decades to treat pulmonary exacerbations. The lower density and higher viscosity of heliox relative to nitrogen oxygen mixtures can signifi cantly reduce airway resistance, thought little evidence exist regarding effi cacy in viral-related lung disease. Th e morbidity and mortality of these viruses is signifi cant with regard to infants and children. In the summer of 2014 > 600 kids were admitted to Comer Children’s Hospital with rhinovirus-enterovirus. Infections in children may cause bronchitis, viral bronchiolitis and pneumonia in variable combinations and may impede air-fl ow enough to be the etiology of respiratory failure. We present the case review of two pediatric patients treated with heliox who experienced resolution of respiratory failure through the use of heliox. First case; a10-month old Hispanic male diagnosed with a history of seizures, coronavirus – HCoV-43 and rhinovirus-enterovirus treated with high fl ow nasal cannula and heliox to avoid re- intubation. Before heliox the patient was tachypnea 60-70 breaths/min. Aft er heliox, his respiratory rate fell 31-38 breaths/min.Th e second case review is a 4 year old female, diagnosed with rhinovirus-enterovirus that required mechanical ventilation with heliox to treat refractory hypoxichypercarbic (PaCO2-118 mmHg) respiratory failure. Th e benefi t of heliox appeared to serve as a bridge to support these patients’ while time and pharmacologic measures took eff ect and an underlying infection abated. More study is needed to understand and treat viral-related obstruction lung disease of small airways and the role of heliox.

A difficult airway management situation was presented by an eight-week-old infant who presented with a bleeding orbital tumor. Th e infant also had a not yet diagnosed inherited trisomy 15 with facial abnormalities and an upper respiratory tract infection that made the face-mask ventilation and tracheal intubation more challenging. The urgent need for the surgery precluded any further work-up and optimization. Anesthetic challenges included difficult mask ventilation, difficult endotracheal intubation, extremely reactive airway and very labile hemo-dynamics during induction. An Air-Q laryngeal mask airway was used as a rescue airway device and as a portal for endo-tracheal tube placement during the anesthetic management with good outcome.

Time : 14:40-15:05
A Boufersaoui completed his Doctoral studies in Medicine from University of Medical Sciences of Algiers and its specialty pediatric studies in the same university. It is currently completing a Doctoral thesis on inhalations foreign bodies in children. He presented his experience in different pediatric congresses: International Congress of Pediatrics in El Baha Saudi Arabia, Congress of the Italian Society of Pediatrics, Congress of the Romanian Society of Pediatrics, First Prize at the Congress of Arab societies of pediatrics at Marrakech, North African pediatrics’ Congress, pediatric pulmonology international Congress in Bruges, Congress of the European respiratory society in Munich. He published an article in the International Journal of Pediatric Otorhinolaryngology on the same subject.
Objectives: Th e objective of this study is to analyze the epidemiological, clinical, radiological and endoscopic characteristics of pediatric foreign body aspiration in Algeria. Methods: In this retrospective study, the results of 2624 children younger than 18 years admitted in our department for respiratory foreign body removal between 1989 and 2012, were presented. Most of them had an ambulatory rigid bronchoscopy. Results: Th e children (62.34% males and 37.65% females) were aged 4 months to 18 years with 66% between 1 and 3 years. Choking was related in 65% of cases. Th e delay between aspiration and removal was 2–8 days in 65.8% and within 24 h in 9.2%. In the most cases, the children arrived with cough, laryngeal or bronchial signs and unilateral reduction of pediatric vesicular murmur. Th e examination was normal in 13%. Th e most common radiologic fi nding was pulmonary air trapping (40.7%).
Th e aspirated bodies were organic in 66.7%, dominated by peanuts, while sunflower seeds, beans and ears of wheat were the most dangerous. In the other cases, they were metallic or plastic as pen caps and recently scarf pins. Th e endoscopic removal by rigid bronchoscopy was successful and complete in 97%. Cases with extraction failure (3%) limited to certain FBs, all of them inorganic were assigned to surgery. Th e complications related to the endoscopic procedure were 0.29% with a mortality of 0.26%. Conclusion: Foreign body aspiration is a real public health problem in Algeria. Th e best way to manage it is an early diagnosis and a rigid bronchoscopy removal under general anesthesia used by fully trained staff . Th e prevention of this domestic accident should consider the population lifestyle and cultural habits to be more eff ective.

Title: Using a supportive community group process to cope with the trauma of social fragmentation and promote re-socialization in Bahamas
Time : 15:05-15:30
Keva Bethell has completed her Master’s in Public Health from the University of Oklahoma Health Sciences Centre and Bachelor of Science in Biology (Pre-med) from Oral Roberts University. She is the Director of Research for the Family: People Helping People project, a community based project which provides free group therapy in marginalized Bahamian communities. The project’s goal is to encourage re-socialization of participants who attend the weekly group sessions. She has published four papers in reputed journals and is currently working on a manuscript detailing a phenomenon called ‘The Evil Violence Tunnel’.
The Family: People helping people project is a supportive group process modality involving the sharing of personal stories, self-examination, refl ection and transformation using psychotherapeutic principles. Th e group process was developed to confront the prevailing social fragmentation in the Bahamas associated with or caused by the continuing eff ects of the countrywide crack cocaine epidemic of the 1980s and the fall-out due to the recent international fi nancial downturn. Facing community disintegration, high youth unemployment and burgeoning rates of violent crime and murder, many persons have been severely traumatized. Th is paper reviews the major themes presented in 776 group process sessions indicating the pervasive nature of the negativity of the shame process expressed in the high incidence of anger, violence, grief, relationship issues and abuse. Th is innovative project has been proven to enhance the re-socialization of many participants in the program.

Ellis-van Creveld syndrome (EvC) is a ciliopathy with cardiac anomalies, disproportionate short stature, polydactyly, dystrophic nails and oral defects. Approximately 60% of EvC patients have severe congenital heart defects (CHD), of which more than half are atrio-ventricular septal defect and common atrium. In this study, we report one EvC Vietnamese family with an atypical CHD phenotype, short chordalis. A 32-month-old boy had a novel heterozygous EVC mutation (c.1717C>G-p.S572X) in exon 12, inherited from his father whose phenotype was milder than his son’s. Of note, the mother without an EvC phenotype showed a lower expression of EVC mRNA compared with controls. SNP array analysis revealed that the patient and mother had a heterozygous 16kb deletion in EVC, ranging from intron 9 to intron 11. As the patient and the father had an atypical CHD, we screened EFCAB7 and IQCE as the candidate for modifiers of EvC phenotype. EFCAB7 and IQCE are ciliary proteins, which positively regulate the Hh pathway and anchor the EVC-EVC2 complex in a signaling microdomain at the base of cilia. A novel missense mutation c.1171T>C-p.Y391H in EFCAB7 was found in the patient and the father. This mutation located in a possible binding site of EFCAB7 and EVC2, and may have modified the EvC phenotype in this family. Our findings suggested the physiological role of EFCAB7 in cardiac development.

A retrospective study of infl uenza-like illness (ILI) in Oman was completed to describe the epidemiology of pandemic infl uenza-A, subtype H1N1 activity (pH1N1). From June to December 2009, 8,941 specimens were collected nationwide from patients that met the case defi nition for ILI, of which 6,547 (73%) were tested for pH1N1 by real-time polymerase chain reaction (RT-PCR). Out of these, 4,089 (62%) were found positive for pH1N1 and 712 (11%) were positive for seasonal infl uenza A. Th e mean age of patients positive for pH1N1 was 24 years (28 days-74 years). Out of the total patients who met the defi nition of severe acute respiratory illness (SARI) and required hospitalization, 28.3% were positive for pH1N1. Th e overall case fatality rate was 1.1 deaths/100,000 populations. Two governorates, Muscat and Dhofar, witnessed the greatest intensity of infl uenza activity. Mitigation, containment, pharmaceutical and non-pharmaceutical measures were engaged. Based on the experience and lessons learned in Oman, some recommendations were sought in Oman.

Introduction: Penetrating or perforating abdominal or chest injuries are very uncommon in the pediatric age group and are associated with a high mortality. Impalement injuries are consequence of penetration by elongated, usually fi xed objects through the body. Case Summary: A 10-year young child suff ered from a penetrating injury to the left iliac fossa when he had fallen down from a coconut tree on to the sharp bamboo fence. Th e bamboo stick penetrated the abdominal wall, perforated the jejunal loops at two sites along with the fundus of stomach, the left diaphragm, upper lobe of the left lung and the bevelled end of the bamboo had exited at the neck aft er tearing apart the neck muscles and skin sweeping along with it few scattered pieces of jejunal tissues which were seen lying alongside. He was brought to the hospital 5 hours aft er the accident. On arrival he was in agony, dehydrated and scored 15/15 on Glasgow scale, remained hemodynamically stable, saturation of 93% with oxygen supplement. On examination a 75x5cm bamboo stick was in situ, which entered 4 cm medial to the left anterior superior iliac spine and exited 3cm above the skin at the posterior triangle of neck. Operation: Imaging modalities were followed by exploration via the left thoraco-abdominal incision. Th e thorax, mediastinum and neck were assessed in the beginning and aft er confi rming that no great vessels were at risk, the foreign body was then carefully removed. Th e perforated stomach, jejunum and diaphragm were repaired. Th e upper lobe of lung had to be resected. An abdominal drain and two inter-costal drains were placed. Th e total operative time was 3.30 hours and the child was managed in intensive care for 4 days and was fi nally discharged aft er two weeks. Conclusion: A rare penetrating injury with damage to the multiple organs could be managed successfully possibly because of teamwork and also due to some sensible move by the villagers as they did not try to fi ddle around with the foreign body.

Title: Prevalence and risk factors for low vitamin D status among breastfeeding mother and infant dyad in an environment with abundant sunshine
Time : 17:30-17:55
Dr. Khalil Salameh has completed his M.D at the age of 24 years from Zagreb University and postgraduate residency in Jordan. He has a membership of royal college of physicians in Edinburgh. He is the chairman of pediatrics department in Al Wakrah Hospital, Doha, Qatar. He has published more than 10 articles in international journals.
High-risk populations are scarce despite reported increased risk of rickets in breastfed infants. We determined the prevalence and associated risk factors low vD status in breastfeeding mother-infant dyads in a population with high prevalence of infantile rickets. Patients & Methods: We evaluated vD status of 60 consecutive exclusively breastfeeding Arab mother-infant pairs in Doha, Qatar participating in a high dose vD supplementation study to prevent vD defi ciency, prior to study enrollment during August to September 2014 (sunny months). Serum 25(OH)D and PTH were measured within 1 month postpartum. Demographic, sun exposure and vD supplementation data were collected using standardized questionnaires. Vitamin D defi ciency was defi ned as serum 25(OH)D <50nmol/L and severe defi ciency as 25(OH)D < 25noml/L in mothers and infants. Results: Mean maternal age was 29 years and 77% had college or university education. Maternal median 25(OH)D was 32.5 nmol/L. Seventy-eight percent of mothers were defi cient and 20% had serum 25(OH)D <25 nmol/L. Negative correlation between serum 25(OH)D and PTH was not statistically signifi cant(r= -0.22, p=0.09). In the entire group, only 50% of mothers had reportedly taken vD supplements with median dietary vD of 119 IU/day. Median maternal sun index score (sun exposure (hrs/wk) x body surface area exposed while outdoor) was 0. Maternal serum 25(OH)D correlated with age (p<0.02), and percent BSA exposure while outdoor (p<0.004). Infant median 25(OH)D was 20.0 nmol/L and 83% were defi cient while 64% had serum 25(OH)D <25nmol/L. Infant 25(OH)D correlated with maternal levels (r= 0.41, p =0.001). None of infants had received vD supplement at 1 month of age and median sun index score was 0. Infant’s serum PTH showed signifi cant negative correlations with 25(OH)D (r= -0.28,p=0.03). Conclusion: Vitamin D deficiency is common in breastfeeding mothers-infants dyad and severe deficiency is more common in infants than mothers in this sunny environment. Low maternal and infant vitamin D status is associated with lack of sun exposure and low or lack of vD supplement intake. We suggest corrective vD supplement strategy to prevent vD deficiency in breastfeeding mothers and their infants, which should preferably start during pregnancy.
