Intravenous fluorescein angiography is a commonly performed and extraordinarily valuable diagnostic procedure. The frequency of adverse reactions after angiography has varied considerably in previous reports. In a prospective study of 2789 angiographic procedures in 2025 patients, the authors found that the percentage of adverse reactions depended strongly on the patient's angiographic history. Overall, adverse reactions followed 4.8% of the angiographic procedures. These reactions included nausea (2.9%), vomiting (1.2%), flushing/itching/hives (0.5%), and other reactions (dyspnea, syncope, excessive sneezing) (0.2%). No cases of anaphylaxis, myocardial infarction, pulmonary edema, or seizures occurred. The percentage of reactions was 1.8% for patients who had had previous angiography without ever having had an adverse reaction. In contrast, the percentage of reactions was 48.6% for patients who had had an adverse reaction to angiography previously.

Although sneezing is a particularly common symptom, there are surprisingly few references to this subject in the medical literature. Many of these references are shrouded in superstition and unscientific theory. Preparation of this report was stimulated by an interesting example of severe uncontrollable non-allergic paroxysmal sneezing which was carefully investigated with regard to both physical and psychological factors. A further example of paroxysms of sneezing occurring in a patient with temporal lobe seizures is also discussed with particular reference to the control of the sneezing episodes in association with anticonvulsant medication and control of the epileptic attacks. In addition, the neurophysiological mechanisms of sneezing are reviewed and the specific neurological references to the subject are discussed in relation to physiological and clinical data. At times the symptom of sneezing would appear to reflect some unknown disorder which may have central and possibly cortical affiliations.

Pertussis in adolescents and adults is common, endemic, and epidemic worldwide, and its incidence is reportedly increasing. Although a number of individuals suffer only a mild cough, many others have symptoms typical of pertussis, causing prolonged cough illness, frequent use of health care resources, missed work and a variety of complications. Symptoms experienced by adolescents and adults include sleep disturbance, weight loss, pharyngeal discomfort, influenza-like symptoms, sneezing attacks, hoarseness, sinus pain, headaches and sweating attacks. Even when symptoms are typical of pertussis, the diagnosis is often not considered in adolescents and adults because of a low awareness of the disease in these age groups. Contrary to common perceptions, complications of pertussis, including some that are serious, are not infrequent in adolescents and adults. These include urinary incontinence, rib fracture, pneumothorax, inguinal hernia, aspiration, pneumonia, seizures and otitis media. Despite underreporting, hospitalization of adults and adolescents does occur. Many believe that adolescents and adults are the groups most commonly infected with pertussis and are now the major source of contagion to infants and young children. Because of the considerable health burden, there is a need for improved vaccination strategies to prevent disease in adolescents and adults and to reduce the risk of transmission to vulnerable infants.

Pertussis, also known as whooping cough, is an acute respiratory tract infection that has increased in incidence in recent years. The initial catarrhal stage presents with nonspecific symptoms of malaise, rhinorrhea, sneezing, lacrimation, and mild cough. During the paroxysmal stage, severe outbreaks of coughing often lead to the classic high-pitched whooping sound patients make when gasping for breath. The paroxysmal stage is followed by the convalescent stage and resolution of symptoms. Complications vary by age, with infants more likely to experience severe complications such as apnea, pneumonia, seizures, or death. In adolescents and adults, complications are the result of chronic cough. The diagnosis depends on clinical signs and laboratory testing. Both culture and polymerase chain reaction testing can be used to confirm the diagnosis; serologic testing is not standardized or routinely recommended. Although antibiotics have not shown clear effectiveness in the treatment of pertussis, they eradicate nasal bacterial carriage and may reduce transmission rates. Macrolide antibiotics such as azithromycin are first-line treatments to prevent transmission; trimethoprim/sulfamethoxazole is an alternative in cases of allergy or intolerance to macrolides. Immunization against pertussis is essential for disease prevention. Current recommendations in the United States consist of administering five doses of the diphtheria and tetanus toxoids and acellular pertussis (DTaP) vaccine to children before seven years of age, and administering a tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis (Tdap) booster between 11 and 18 years of age. Recent efforts have focused on the vaccination of adolescents and adults, with new recommendations for a single dose of the Tdap booster if it has not been previously administered.
