Knowledge of the military regulations is key to guiding medical evaluations for applicants and service members. Military and civilian allergy consultants are often called on for their expertise to provide guidance with regard to the allergic conditions that may be potentially disqualifying from service per the published regulations for accession and retention. This review focuses on the role of the allergy consultant in military accession, retention, and deployments.

Article Synopsis
  • * Diagnosis typically occurs after age 2, as children have limited polysaccharide responsiveness that matures over time; there’s still uncertainty over specific testing thresholds for nonresponse.
  • * Management includes monitoring and potential treatments like prophylactic antibiotics and immunoglobulin replacement, with a better chance of resolution in children compared to older patients.

Gilbert syndrome is a condition of non-hemolytic hyperbilirubinemia without further sequelae or primary laboratory abnormalities. Gilbert syndrome represents the most common hereditary disorder of bilirubin metabolism and is frequently identified as the etiology of familial jaundice in clinical medicine. This disorder typically manifests as mild unconjugated hyperbilirubinemia of benign nature.

Purpose: Midlife adults (50-64 y) are at risk for falls and subsequent injury; yet current guidance on fall screening only pertains to older adults (> 65 y). Herein, we evaluated whether frailty was predictive of readmission for falls in midlife trauma patients.

Study Design: This was a retrospective cohort study of trauma midlife patients admitted for traumatic injuries from 2010 to 2015.

Article Synopsis
  • Renovascular occlusive disease can be caused by various factors such as atherosclerosis, fibromuscular dysplasia, and rarely, extrinsic compression of the renal artery due to entrapment.* -
  • Two patients with right-sided renal artery entrapment were diagnosed through advanced imaging techniques and successfully treated with open surgical decompression, involving careful exposure of the renal artery.* -
  • Post-surgery, both patients showed improvement in blood pressure control, normal blood flow in the renal artery, and one patient was able to discontinue anticoagulation treatment.*

Purpose: The older population is particularly vulnerable to traumatic injury. Frailty scores, used to estimate the physiologic status of an individual, are key to identifying those most at risk for injury. Global health measures such as the Veterans RAND 12 Item Health Survey (VR-12) are quality of life measures that assess older adults' overall perception of their health and may serve as a useful adjunct when predicting frailty.

Trimethoprim-sulfamethoxazole-induced aseptic meningitis (TSIAM) is a rare adverse reaction to a commonly prescribed antibiotic. We describe a case of severe TSIAM which resembled septic shock. A 30-year-old male with relapsed Hodgkin's lymphoma 25 days status post autologous stem cell transplant presented to our clinic for evaluation of trimethoprim-sulfamethoxazole (TMP-SMX) hypersensitivity.

We report a case of a 14-month-old boy with atopic dermatitis (AD) who presented to our hospital with hypocalcemic tetany and gross motor delay. Further laboratory and imaging confirmed the diagnosis of vitamin D deficiency and rickets. He was breastfeeding and on a restricted diet due to presumed multiple food allergies.

Background: Elderly (65 and older) fall-related injuries are a significant cause of morbidity and mortality. Although frailty predicts poor outcomes in geriatric trauma, literature comparing frailty scoring systems remains limited. Herein, we evaluated which frailty scoring system best predicts falls over time in the elderly.

Importance: Falls have been associated with morbidity and mortality in elderly patients. Assessment of frailty at hospital admission may help health care professionals evaluate fall risk in patients with trauma-related injury.

Objective: To determine whether frailty assessed using the Canadian Study of Health and Aging Clinical Frailty Scale is associated with readmission for falls after index admission for trauma-related injury in patients aged 50 years and older.

Introduction: The purpose of this study was to determine the safety, tolerability and effectiveness of daily administration of an orally administered pantothenic acid-based dietary supplement in men and women with facial acne lesions.

Methods: A randomized, double-blind, placebo-controlled study of adults previously diagnosed with mild to moderate acne vulgaris was performed. Subjects were randomized to the study agent, a pantothenic acid-based dietary supplement, or a placebo for 12 weeks (endpoint).

Chagas' disease, caused by Trypanosoma cruzi, is an important cause of heart disease in Latin America. T. cruzi-induced microvascular compromise, in turn, is thought to play a major role in chagasic heart disease.

A neutral protease with an estimated Mr of about 26 kD and responsible for cleavage ofmyosin LC2 was isolated from hamster skeletal muscle. Complementary DNAs were generated by RT-PCR using total hamster muscle RNA and degenerate oligonucleotide primers based on the sequences of two internal peptides. The nucleotide sequences of the resultant cDNAs were subsequently determined and the complete amino acid sequence of the protease deduced.

Helicobacter pylori, a cause of peptic ulcer disease and certain types of gastric cancers, has usually been cultured on diverse agar-based media, resulting in a requirement for 2 to 4 days of growth at 37 degrees C. We have developed a novel broth medium consisting of a base medium supplemented with 2% newborn calf serum, Mg2+, Cu2+, Fe2+, Zn2+, Mn2+, and 1 mg of lysed human erythrocytes per ml. This medium supports rapid growth of H.

The ability of the vascular endothelium to elaborate cytokines in response to gram-positive sepsis has received limited attention. This study examined cytokine expression by human umbilical vein endothelial cells (EC) following infection with a gram-positive bacterial pathogen, Staphylococcus aureus. S.

The potential role of endothelin-1 (ET-1) in the pathogenesis of focal microvascular spasm, previously implicated in the etiology of Chagas' cardiomyopathy, was investigated. There was an increase in ET-1 in the supernatants of Trypanosoma cruzi--infected human umbilical vein endothelial cells (HUVEC). Infection of HUVEC and vascular smooth muscle cells had no effect on the synthesis of transforming growth factor-beta, which induces ET-1 synthesis.

Extracellular adenosine triphosphate (eATP) has been suggested to play a role in lymphocyte-induced tumor destruction. We now provide evidence that a protein responsible for ATP synthesis in mitochondria may also play a physiologic role in major histocompatibility complex-independent, lymphocyte-mediated cytotoxicity.

Background: Monocyte adhesion to the vascular endothelium, an important component of an inflammatory response, is one of the earliest detected events in the pathogenesis of atherosclerosis. We have identified a monocyte adhesion molecule, recognized by monoclonal antibody (mAb) IG9, on the cell surface of human umbilical vein endothelial cells (HUVEC) treated with tumor necrosis factor-alpha (TNF-alpha), interleukin-1, or lipopolysaccharide. Endothelial cell expression in vitro and in vivo of the protein recognized by mAb IG9 (IG9 protein) was further characterized.

Although fibroblast growth factor has been identified in normal and ischemic myocardium, temporal changes in mitogenic activity due to fibroblast growth factors in ischemic tissue have not been well established, nor has correlation been made with the known early increases in coronary collateral flow. This study sought to measure fibroblast growth factor activity in myocardium after coronary ligation. Accordingly the left anterior descending coronary artery of dogs was ligated and coronary collateral flow measured with radioactive microspheres.

Interactions between the epithelial anlage of the developing mouse inner ear and its associated periotic mesenchyme control the differentiation of the cartilaginous otic capsule. Transforming growth factor-beta 1 (TGF-beta 1) is a naturally occurring signal peptide that is present in these tissues at times of active differentiation and morphogenesis. Previous studies have shown that TGF-beta 1 alone is not a sufficient stimulus to initiate chondrogenesis in cultured periotic mesenchyme.
