The aim of the review is to provide up-to-date information on the multiple roles of epidermal keratinocytes in the immune reactions associated with allergic contact dermatitis and atopic dermatitis skin diseases. In the last two decades, it has become clear that keratinocytes are highly active immunological cells, with major control over the acute and the chronic phases of skin inflammation by means of cytokine/chemokine production and surface molecule expression. Keratinocyte responses in skin allergic reactions are rather disease-specific and keratinocytes from genetically determined skin disorders, including atopic dermatitis, show intrinsic abnormalities in their capacity to respond to trigger factors. Lymphokines and cytokines released by T lymphocytes and other immune cells represent the most important stimuli that elicit the inflammatory activation of keratinocytes. Depending on the type and extent of T-cell infiltrate present in allergic contact dermatitis and atopic dermatitis skin lesions, keratinocytes are exposed to different cytokine micromilieu and, in turn, produce flogosis mediators qualitatively and quantitatively specific for each disease. Keratinocyte-derived inflammatory molecules amplificate skin immune responses associated with allergic contact dermatitis and atopic dermatitis, and contribute to the disease process and clinical phenotype development.

Device problems and improper usage may alter the EpiPen dose. Nurses should review proper EpiPen administration with patients and their families or caregivers.

Malignant central airway obstruction heavily impacts patients' quality of life and its management continues to be a challenge. The current article will review the use of airway stents in this population. Airway stenting is highly effective in palliating symptoms of airway obstruction. There are several types of stents available with different advantages and disadvantages depending mainly on the material they are made from. Clinical outcomes seem to be comparable between silicone and self-expanding metal stents. Self-expanding metal stents have proven to be efficient in recanalizing 'complex' central airway obstructions. Preliminary data show that a new self-expanding 'hybrid' stent appears to be effective and safe for malignant airway obstruction. Airway stent complications vary according to the type of stent and the type of obstruction. Multidetector computed tomography seems to be a valuable adjunct to bronchoscopy in detecting and characterizing stent complications. A clear definition of airway stent-related infection is urgently needed to provide adequate diagnosis and management of this complication. Metal stent fracture is less common in patients with malignant airway obstruction as compared with benign disease, and this could be partially explained by the decreased survival and shorter exposure to stent in the former population. Airway stents are of great help in palliating symptoms of malignant central airway obstruction. Unfortunately, there have been no recent striking advances in stent technology and the ideal stent has yet to be designed.

According to this study: The pediatric inflammatory multisystem syndrome temporally associated with severe acute respiratory syndrome coronavirus 2 has a wide range of presenting signs and symptoms and disease severity. This syndrome appears to differ from other inflammatory disorders seen in children.

In response to COVID-19 pandemic social distancing restrictions, ambulatory care settings have largely transitioned to virtual health care delivery. As local, state, and federal officials discuss timelines for these restrictions to be lifted, ambulatory leadership is tasked with the responsibility of developing reactivation plans for its clinics to resume in-person care. This article discusses a method in which ambulatory leadership can determine the clinic's deficit in patient encounters, set a time period to return to normal operations, planning for space and scheduling changes, balancing in-person virtual visits, and thoughtfully communicating these plans to clinic staff and providers.

Appendicitis is the most common cause of abdominal pain requiring surgery in children. Missed appendicitis is also a frequent cause of professional liability in an emergency department (ED). A retrospective review of all patients with appendicitis diagnosed in the ED was undertaken to identify: 1) how many patients required more than one visit to diagnose appendicitis and 2) the clinical characteristics that distinguished the patients who visited twice from patients who were diagnosed on the first visit. A total of 87 patients with appendicitis were seen by pediatricians in the ED from 1987 to 1989. The patients included 43 girls and 44 boys (mean age, 8.9 years). Six patients (7%) were seen twice before the diagnosis of appendicitis was made. They returned to the ED on average 29 hours after the first visit. The ED discharge diagnosis of the six "missed" patients included: probable Campylobacter (n = 1), viral urinary tract infection (n = 1), gastroenteritis (n = 2), and abdominal pain (n = 2). The six missed patients were different from the other patients with appendicitis. They were more likely to have a normal appetite, to have diarrhea, and to be afebrile. All the patients had at least two of the four following signs and symptoms: vomiting, tenderness, guarding, and right lower quadrant (RLQ) pain. At the time of surgery, 23/81 (28%) of the one-visit group had a ruptured appendix, whereas 3/6 (50%) of the missed patients had a ruptured appendix. 1) Seven percent of the patients were seen twice in our ED before the diagnosis of appendicitis was made.(ABSTRACT TRUNCATED AT 250 WORDS)

Teen mothers often face a stigmatizing gaze based on the belief that early childbearing jeopardizes their life chances and the health and development of their children. Growing evidence suggests that the poor maternal-child outcomes associated with early childbearing have been overstated and may be explained by teen mothers' childhood disadvantage and adversities. After reviewing what is currently known about the relationships between early childbearing and maternal-child outcomes, as well as teen mothers' perspectives on mothering, clinical practices are suggested that address teen mothers' concerns, strengths, aspirations, and the long-term inequities that contribute to poor outcomes.

Foreign bodies being forced into the esophagus as a form of fatal child abuse is rare. A 4.5-month-old female infant presented to clinicians with respiratory distress. Several coins were recovered from the esophagus. One month later, she was found dead in her crib. At autopsy, there were three coins in the esophagus. In addition, there were cutaneous contusions of various ages, acute and partially healed fractures of the extremities, old aspirated foreign material in the lungs, and pulmonary fat emboli. Although the fat emboli may have contributed to the death, several potentially fatal mechanisms from the esophageal foreign bodies deserve consideration. These include vagal stimulation from esophageal distention, aspiration of swallowed fluids after esophageal obstruction, compression of the trachea or the heart by the coins, and cardiac compression or airway occlusion by the introducing finger.

WHIM syndrome (the association of warts, hypogammaglobulinemia, recurrent bacterial infections, and 'myelokathexis') is a rare congenital form of neutropenia associated with an unusual immune disorder involving hypogammaglonulinemia and abnormal susceptibility to warts. In this review, we describe the clinical, laboratory and genetic features of WHIM syndrome. The identification of chemokine receptor CXCR4 as the causative gene of WHIM syndrome yields new interest in the study of this disease as a model for the comprehension of CXCR4 biology in humans and highlights the importance of the chemokine network for inducing effective immune responses and governing leukocyte trafficking. CXCR4 participates in several biological processes (bone marrow hematopoiesis, cardiogenesis, angiogenesis, neurogenesis) and is implicated in different clinical pathologic conditions (WHIM, HIV infection, tumor metastatization, autoimmunity). Pharmacologic agents that modulate CXCR4 expression/function are already available and promise a wide range of future clinical applications.

Hepcidin is a recently discovered hepatic peptide that regulates intestinal iron absorption as well as maternal-fetal iron transport across the placenta. It probably also affects the release of iron from hepatic stores and from macrophages involved in the recycling of iron from hemoglobin. Connecting iron metabolism to innate immunity, hepcidin is a key mediator of hypoferremia of inflammation. The essential role of hepcidin in iron metabolism is being elucidated through mouse and human genetics, biochemistry, and cell biology. Studies of hepcidin are leading to fundamental understanding of iron homeostasis and pointing to potential treatments for hemochromatosis and anemia of inflammation (anemia of chronic disease).

Fifteen eyes in 12 patients with Salzmann's nodular corneal degeneration developed symptoms of recurrent erosion, decreased vision, or both. A history or evidence of ocular surface disease was present in 14 of 15 eyes. Removal of the nodule and accompanying pannus or corneal epithelial basement membrane degeneration, provided symptomatic improvement in all patients.

Blindness can result from pressure on the optic nerve in the optic canal, either from trauma or from neoplasm. The usefulness, timing, and technique of surgical decompression of the optic canal remains controversial. The present paper describes eight patients with optic nerve compression, who had the optic nerve decompressed through a transorbital approach. Because this technique is technically simple and is associated with a low morbidity, it offers a treatment alternative to this difficult group of patients.

This report is an attempt to point out a hazard of what would be otherwise competent treatment of acquired spinal stenosis, namely laminectomy and facetectomy, in a small group of patients who are osteoporotic and who also have a "minor" compression fracture in the area in which the surgery is contemplated. Three patients who had such laminectomies, with disastrous results, are presented, along with one patient who, instead, had internal fixation and fusion at the time of laminectomy with an excellent result. The latter approach is recommended in such cases.
