Recurrent infections and joint pain.

A seven-year-old white male presented with recurrent bouts of paranasal sinusitis, streptococcal pharyngotonsillitis, lower respiratory tract infections, continuous low-grade fever, and conjunctivitis, which required frequent use of antibiotics over a period of two years. A careful review of systems also revealed a six-month history of arthralgia affecting his knees, elbows, and hands, which limited his daily activities. Prominent in the history were recurrent bouts of a generalized salmon-red, nonpruritic rash, which was most pronounced on the face and trunk and which was exacerbated by fever.

A phase I study of the safety of honeybee venom extract as a possible treatment for patients with progressive forms of multiple sclerosis.

Although several reports suggest that bee venom may be an effective treatment for patients with multiple sclerosis (MS), patients may be subjected to real risks of serious allergic reactions as well as emotional and economic costs. This study was conducted to evaluate the safety of bee venom extract as a possible treatment for patients with progressive forms of MS. A total of nine bee venom nonallergic patients with progressive forms of MS, who were 21-55 years of age with no other illnesses, were entered into four groups (A, B, C, and D) on a structured 1-year immunization schedule.

Current epidemiology of asthma: emerging patterns of asthma.

Asthma is a chronic disease associated with substantial morbidity, mortality, and health care use. Between 1980 and 1994, the self-reported prevalence of asthma increased 75% among all race, sex, and age groups in every region of the United States. Although an estimated 14.

Are attention deficit hyperactivity disorder and chronic fatigue syndrome allergy related? what is fibromyalgia?

Despite the progress made in the field of allergy-immunology in recent years, there are a group of diseases that the allergist-immunologist may be called on to manage in which their precise etiologies have not been identified but that appear to be initiated or exacerbated by allergic mechanisms. Attention deficit hyperactivity disorder (ADHD), chronic fatigue syndrome (CFS), and fibromyalgia (FM) fall into this category of disorders. Although the precise etiology of ADHD still remains unknown, the most prevalent theory is that it represents a neurobiologically based developmental disability leading to inadequate production of the neurotransmitter dopamine.

IgE and non-IgE food allergy.

Background: Food allergy (FA) is characterized by an abnormal immunologic reactivity to food proteins. The gastro-intestinal tract serves not only a nutritive function but also is a major immunologic organ. Although previously thought to be triggered primarily by an IgE-mediated mechanism of injury, considerable evidence now suggests that non-IgE mechanisms may also be involved in the pathogenesis of FA.

Developmental immunology: clinical application to allergy-immunology.

Background: An increase in prevalence of allergic diseases has been seen at an unprecedented rate in many countries throughout the world. Associated with this increase in allergic disease has been a disturbing increase in morbidity and mortality of such diseases as asthma despite the availability of several new therapeutic agents over the past 2 to 3 decades. The search for both environmental factors, eg, new allergens, as well as biologic markers of genetic susceptibility, eg, respiratory viruses, has yielded considerable promise for an explanation for this rising prevalence of allergic disease.
