  • This is a concise description of the clinical manifestations frequently seen in the more common respiratory disorders affecting pediatric patients. After a brief description of each disease, the clinical findings associated with the disorder are summarized in table format. Students are cautioned that the tables represent a summary of the “classic” findings in moderately advanced cases. In reality the occurrence and degree of the typical findings vary with the severity of the disease and the patients overall health status.

  • Neutrophil Abnormalities A defect in the neutrophil life cycle can lead to dysfunction and compromised host defenses. Inflammation is often depressed, and the clinical result is often recurrent with severe bacterial and fungal infections. Aphthous ulcers of mucous membranes (gray ulcers without pus) and gingivitis and periodontal disease suggest a phagocytic cell disorder. Patients with congenital phagocyte defects can have infections within the first few days of life. Skin, ear, upper and lower respiratory tract, and bone infections are common. Sepsis and meningitis are rare.

  • Approach to the Patient: Disorders of the Sense of Smell Unilateral anosmia is rarely a complaint and is only recognized by testing of smell in each nasal cavity separately. Bilateral anosmia, on the other hand, brings patients to medical attention. Anosmic patients usually complain of a loss of the sense of taste even though their taste thresholds may be within normal limits. In actuality, they are complaining of a loss of flavor detection, which is mainly an olfactory function.

  • Infections of the Ear and Mastoid Infections of the ear and associated structures can involve both the middle and external ear, including the skin, cartilage, periosteum, ear canal, and tympanic and mastoid cavities. Both viruses and bacteria are known causes of these infections, some of which result in significant morbidity if not treated appropriately. Infections of the External Ear Structures Infections involving the structures of the external ear are often difficult to differentiate from noninfectious inflammatory conditions with similar clinical manifestations.

  • Newborn and infant mortality has been a plague of public health for centuries. However, during the 1900s, an extraordinary effort began to correct this disgraceful situation. Especially remarkable have been the accomplishments of the last 30 years or so. Although many challenges remain, very noticeable progress has been made relative to some specific causes of death in babies. In the United States, neonatal respiratory distress syndrome (NRDS) was one of the main causes of death in premature newborns.

  • Stroke is a vascular disease for which mortality and morbidity are relatively well-documented because most stroke victims are admitted to hospitals. Trends in stroke mortality, incidence, and prevalence are somewhat similar to those for other cardiovascular conditions. Stroke mortality has been decreasing since the 1960s, but without a consistent decrease in stroke incidence. Stroke incidence has even been reported to have been higher in the 1980s than during the 1970s, and there was no sustained decline in incidence during the 1990s....

  • Orbital Cellulitis This causes pain, lid erythema, proptosis, conjunctival chemosis, restricted motility, decreased acuity, afferent pupillary defect, fever, and leukocytosis. It often arises from the paranasal sinuses, especially by contiguous spread of infection from the ethmoid sinus through the lamina papyracea of the medial orbit. A history of recent upper respiratory tract infection, chronic sinusitis, thick mucous secretions, or dental disease is significant in any patient with suspected orbital cellulitis. Blood cultures should be obtained, but they are usually negative.

  • The negative health impact of many large-scale public health emergencies, such as an intentional anthrax release, severe acute respiratory syndrome (SARS), or the recent 2009 H1N1 influenza pandemic, can be mitigated significantly by medical countermeasures such as antimicrobials, antivirals, and vaccines. To be effective, these countermeasures generally must be delivered in very large quantities in a short period of time.

  • Particles, as noted above, can provide an exposure pathway for SVOCs, but they also can present a serious health risk on their own. They range in size from very small (0.001 μm to 10 μm), which can remain in the air for a long time, up to relatively large (100 μm), which quickly settle out of calm air. Inhaling particulates can cause eye, nose, and throat irritation and can increase the risk for respiratory infections. Health care professionals are especially concerned about the long-term effects of inhaling ultrafine particles (less than 2.

  • Over the last two decades, significant progress has been made in the field of rhinology—some even feel they have been the two most exciting decades for rhinology so far. Basic research increased our knowledge of the pathophysiology of rhinosinusitis, of allergy and immunology, environmental and developmental problems, as well as of smell, taste, and genetic features. Imaging technologies with reduced or even no radiation, CT and MRI, allowed for pictures of anatomical structures and pathological processes, for three-dimensional visualization unheard of before.

  • A comprehensive search of the scientific literature for this report is complete through September 1991. In addition, pertinent studies published through July 1992 have been included in the analysis in response to recommendations made by reviewers. Due to both resource and time constraints, the scope of this report has been limited to an analysis of respiratory effects, primarily lung cancer in nonsmoking adults and noncancer respiratory illnesses in children, with emphasis on the epidemiologic data.

  • While oral conditions are important in and of themselves, there is an increasing awareness regarding their contribution to the incidence and severity of other diseases. Conditions that may be affected by poor oral health include diabetes, respiratory diseases and cardiovascular health.

  • Drugs Acting on Motor Systems spinal disorders. Benzodiazepines enhance the effectiveness of the inhibitory transmitter GABA (p. 226) at GABAA receptors. Baclofen stimulates GABAB receptors. !2-Adrenoceptor agonists such as clonidine and tizanidine probably act presynaptically to inhibit release of excitatory amino acid transmitters. The convulsant toxins, tetanus toxin (cause of wound tetanus) and strychnine diminish the efficacy of interneuronal synaptic inhibition mediated by the amino acid glycine (A).
