The human herpes virus 6 (HHV 6) may induce not only the wellknown condition of exanthem subitum, but also a number of more common (cf. Part 1) or rare, even previously unknown, clinical manifestations. Part 2 of this paper deals with the more rarely observed manifestations. These include complications of ARD (sinusitis, otitis media, bronchial pneumonia) hepatitis, encephalitis or Pfeiffer's disease (mononucleosis-like syndrome). In individuals with a relevant disposition (genetic HLA/DR type?) initiation or (re-)activation of rheumatoid arthritis (JCA = juvenile chronic arthritis) or chronic iridocyclitis may occur. Although, on account of the high prevalence of vaccination in our population (approximately 95%), prenatal infections are extremely rare, they may manifest in a severe "septic" form (fatalities have occurred) or may lead to neurological deficits (comparable with cytomegalovirus infection). To date, no specific therapy (e.g. gammaglobulin, virostatics) or reliable preventive measures (e.g. vaccination) are available.

Many middle ear reconstructive procedures would be facilitated by use of a relatively safe surgical adhesive. A fibrinogen-based adhesive (Tisseel) has been effective in otologic surgery in Europe, but because it is derived from pooled human blood, it carries a risk of transmitting hepatitis, acquired immune deficiency syndrome, and other illnesses. This report details a new procedure for creating an autologous fibrinogen-based adhesive, obviating these risks. The fibrinogen and factor XIII component of the adhesive was isolated by polyethylene glycol precipitation from human plasma within a few hours, and was used either immediately or frozen for use up to 3 weeks later. Fifteen chinchillas had either the single donor adhesive, the commercial European adhesive, or saline placed on the oval and round windows, and no evidence of cochlear, mucosal, or ossicular damage was seen by light microscopy 30 days later. Auditory brain stem response thresholds remained stable, except in three animals that developed otitis media. Based on this investigation, autologous fibrinogen-based adhesive appears promising as a relatively safe, biological bonding material for otologic surgery, and is worthy of further study.

Circulating immune complexes are thought to play an essential part in the pathogenesis of necrosing angiitis. This theory also allows a role to be attributed to certain infectious agents (viral, bacterial, parasitic) in the development of periarteritis nodosa (PAN). An infectious syndrome was found in all our 9 patients, aged 26 to 69 years, with histologically confirmed PAN: previous infection (over 15 days before hospital admission): otitis, hepatitis B, tonsillitis, ascaris (Case n.7), pulmonary tuberculosis, brucellosis, seropositivity for Chlamydia trachomatis (Case n.9), paratyphoid (Case n.5), seropositivity for Yersiniosis pseudo-tuberculosis (Case n.2), seropositivity for Chlamydia trachomatis (Cases 3 and 4), seropositivity for toxoplasmosis (Cases 4 and 6), seropositivity for rubella (Case n.8). Recent infection (less than 15 days before hospital admission): staphylococcus aureus septicaemia (Case n.1); Group A betahemolytic streptococcal urinary infection (Case n.2); Group A betahemolytic streptococcal otitis media; pseudomonas aeruginosa and Klebsiella septicaemia; enterococcal cystitis (Case n.4); progressive pulmonary tuberculosis (Case n.6), acinetobacter pneumonia (Case n.9). The HBs antigen was only found in one patient (Case n.6), who had an active hepatitis.

An infant who received multiple transfusions during the first few days of life for rhesus disease became ill with recurrent infections when 6 months old. Hepatitis, thrush, Candida dermatitis, otitis media, and disseminated Mycobacterium avium intracellulare infection occurred by 14 months of age. Immunological studies showed raised immunoglobulin levels, decreased mononuclear-cell responses to allogeneic cells and mitogen, and a decreased helper/suppressor cell ratio. It was determined that one of the blood donors, who was well at the time of blood donation, had died 17 months after with multiple opportunistic infections and acquired immunodeficiency. The clinical and laboratory findings in our patient suggest that he acquired a transmissible infectious agent from a blood transfusion, resulting in acquired immunodeficiency, and that this agent was not cytomegalovirus, Epstein-Barr virus, or hepatitis B virus.

A retrospective record study of six cases of meningitis caused by group A beta-hemolytic Streptococcus is presented. Associated findings included otitis media, pharyngitis, and erysipelas. All patients survived their infections despite major complications including seizures, shock, coma, renal failure, and hepatitis. Two patients had neurologic sequelae. Group A Streptococcus causes a severe form of bacterial meningitis in apparently healthy children.

We evaluated clinical presentations and complications retrospectively in 48 pediatric patients hospitalized for suspected measles during a measles epidemic in Chicago. Fifty-one percent were < 15 months of age and 75% were < 4 years of age. Measles, diagnosed in 44 patients, was culture-proved in 18. Presentations were not always classic. Respiratory complications, otitis media, hepatitis, preterm labor, keratitis and central nervous system involvement were reported. The presence of stomatitis and hypotension in some patients raised the differential diagnoses of Kawasaki disease and toxic shock syndrome. Six patients with stomatitis, admitted with a measles-like illness, fulfilled the Centers for Disease Control and Prevention criteria for Kawasaki disease. Three were diagnosed with Kawasaki disease and 3 with measles. In addition to serology and echocardiographic changes, the platelet count and the erythrocyte sedimentation rate may be useful in distinguishing between measles and Kawasaki disease. Two of 10 patients with hypotension met the Centers for Disease Control and Prevention criteria for toxic shock syndrome. The diagnosis of measles, solely on clinical grounds, may therefore not be as straightforward as is generally accepted.

The effects of measles are relatively mild in well-nourished children, but are associated with high mortality in those who are malnourished and in those who have other diseases. Complications may include bacterial pneumonia, bronchitis, otitis media, gastroenteritis, myocarditis, hepatitis, and encephalomyelitis. The Expanded Program on Immunization was introduced to India in 1978, but measles immunization did not commence until 1985 under the Universal Immunization Program. Total district coverage was achieved in 1990, followed by a peak immunization coverage figure of 90.9% in 1991. Coverage rates declined, however, to 85.8% in 1992-93. Impressive though they may be, these coverage rates obfuscate the reality that measles remains a major cause of morbidity and childhood mortality in India. Coverage levels remain under 50% in many tribal and remote areas, with 49,453 notified cases at the time of printing. Overall case fatality rates for the country are in the range of 2-15% due to a synergistic relationship between malnutrition and infection. One must therefore not rest in the fight against measles. Sudden outbreaks should be reported immediately and vitamin A supplements and immunization supplies readied in anticipation of epidemic. The many reasons why vaccine coverage rates remain low in some areas include the failure of many parents, health personnel, and some doctors to regard measles as a serious disease; restrictive vaccine administration directives requiring the presence of a physician; physician reticence to open a 10-dose vial for 1-2 patients; and parental and physician reluctance to immunize children who are slightly ill or where minor adverse side reactions such as fever and rash may be anticipated.
