Upper Oesophageal Foreign Body with Acute Drooling in a Child with Congenital Hypotonia

Foreign body ingestion and aspiration commonly affect children. The most vulnerable age is early childhood when children tend to explore new objects with their mouths or by an accident by elder siblings. A 2-year-old female child who is known to have congenital hypotonia, status post laparoscopic fundoplication and gastrostomy tube feeding (G- tube) inserted at age one year. Then she was in stable condition till when presented with acute unexplained drooling of frothy whitish secretions, mild cough and difficulty breathing with hypoxemia. X-ray chest and upper abdomen revealed normal. She underwent flexible bronchoscopy revealed normal and then direct laryngoscopy was extracted a covering plastic of the feeding tube in the upper end cervical oesophagus by Magill forceps technique. Subsequently her symptoms resolved completely. To increase the likelihood of identifying foreign body ingestion and aspiration, healthcare professionals should maintain a high index of suspicion even in children with neuromuscular disorder.

Validation of an Anti-Protective Antigen ELISA for Quantitative IgG Evaluation in B. anthracis Immunized Horses

The potency test for anthrax vaccines has historically involved the challenge of actively or passively immunized laboratory animals with a fully virulent strain of Bacillus anthracis. Lethal challenge studies with the archetypal virulent strains such as B. anthracis Ames strain present considerable difficulties in laboratory management and handling and are too inefficient for the early evaluation of alternative preventative and therapeutic interventions. An ELISA for the evaluation of antibody response to protective antigen (PA) in horses immunized with the Sterne 34F2 strain spore vaccine was developed. The objective of this work was to study the performance of this assay in terms of the guidelines set forth by the International Conference on Harmonics (ICH) and the Center for Biologics Evaluation and Research (CBER) for analytical procedures. We have demonstrated a working range for this assay (73-1581 EU/ml) on the bases of the following parameters: linearity (25 and 1,662 EU/ml, r2 = 0.9988, p < 0.001), accuracy (94.8 - 105.4 %, recovery within the range of 25 and 1,662 EU/ml), precision (≤ 17.6 % CV, repeatability; ≤ 15.7 and ≤ 13.1 % CV, intermediate precision per day and per analyst, respectively), limit of detection (2.25 EU/ml) and limit of quantitation (25 EU/ml). The assay was also demonstrated to be specific for the evaluation of anti-PA IgG antibodies. Based on the assay performance characteristics it was determined that the assay was adequate for use in B. anthracis immunogenicity testing in horses.

Epidemiology of Sudden Unexpected Death in Infancy: Evidence from the London Metropolitan Police Project Indigo Investigation

The London Metropolitan Police in collaboration with medical personnel, study all sudden unexpected death in infancy (SUDI) <2 years in their jurisdiction, to identify suspicious cases for further investigation. The 2005-2010 Project Indigo includes extensive data on all such non-suspicious cases. Deidentified data on age and gender of 477 infants dying a natural unexpected-sudden death in London were gathered for statistical analyses, for comparison to our published a priori probability models that predict their distributions without need of superfluous information, such as race, autopsy findings, or SUDI risk factors. The total observed male fraction of 0.5639 for all these 477 Indigo cases (269 male) is predicted using a recessive X-linkage model for Sudden Infant Death Syndrome (SIDS) as 0.5676. The transformed age distribution of all 477 Indigo cases of different causes of death is modeled by a single four-parameter lognormal distribution, y = Log [(d + 9.44)/(1254 – d)] = μ + σ z, where d is Indigo age in calendar days of life (d = DOD – DOB ≥ 0), median μ = -1.085, slope σ = 0.543, and z is a standard normal deviate.

Research in Fracture Healing and Its Clinical Applications in the Veterinary Practice

Bone healing is a complex process consisting of multiple sequential phases needing the coordinated interaction of various cells, growth factors, cytokines and mechanical conditions. However, bone healing is one of the rare regenerative processes resulting in complete restoration of form and function. Fracture treatment aims towards a swift return to functional use of the injured limb. Therefore stabilization is a key requisite. In the veterinary clinic difficult fracture cases often require a unique stabilization by custom made external fixation. While this fixation technique harbors risk factors it offers a high flexibility essentially needed to successfully treat small animal fracture patients. Here we draw the connection between the up-to-date knowledge in bone healing and case reports of external fixation techniques from the small animal practice with respect to benefits and risk factors.

Forensic Science Curricular and Career Planning: A Modified Systems Theory-Based Model for Student Advising

Following the rise in popularity of forensic science, fueled by the media and perhaps necessity, comes the demand for an effective and productive approach to advising students interested in a career in this vast area. Forensic science is a large-scale umbrella term encompassing a multitude of disciplines. Whereas “forensic” means legal, any discipline that has an application to law or the legal system may be considered a “forensic science”. With the seemingly ever-increasing lure of forensic science as a career option, the question arises as to how best to assist students in making a dream job a reality. The purpose of this research is twofold: (1) summarize findings from forensic science job listings in the United States and (2) provide a framework, derived largely from Systems Theory, for understanding the advisee skillset, and suggest a model for a step by step career decision-making and curricular planning approach for professionals working in an advising capacity.
