Identification and measurement of rubella antibody of 19 S (IgM) and 7 S (IgG) immunoglobulins by sucrose density gradient centrifugation and a modified hemagglutination-inhibition (HAI)-test is described. Human group 0 of red blood cells were employed after trypsination. The method proved to be highly reliable and sensitive for the rapid detection of rubella IgM antibody in routine research to make an accurate diagnosis of recent rubella infection. Sera from 185 pregnant women, 200 children suspect of congenital infection, 15 mothers of intrauterin infected children, and 32 cases of rubella vaccine-induced immunity control were studied. In postnatal rubella infections, specific IgM-antibody could be detected in all sera after the onset of the rash up to eight or ten weeks after infection. From March 1973 until September 1974 laboratory diagnosis confirmed 30 of 185 pregnant women to have been recently infected with rubella. In less than 3% (4 cases) the results could not confirm or exclude a recent history of rubella. Among 200 children with congenital defects or some irregular development, specific IgM antibody was detected in 36 cases. The diagnosis of congenital rubella was confirmed or detected in the first months of life. One of the infected children was well at birth but later developed mental retardation and hearing loss, and some others showed only minor defects. In some children rubell IgM antibody persisted 5-14 months. IgM rubella antibody was not found in the sera of 15 mothers from children with intrauterine infection confirmed by IgM antibody demonstration. Post-vaccination-tests showed serum IgM and IgG immunoglobulin-responses to be similar to the natural rubella-virus-infection. Maximal titers of both immunoglobulin-fractions were but four-fold lower after vaccination (28 of 32 tested cases). The described method is able to verify the time of infection by testing a single serum. The HAI-test of the 12 fractions collected from each serum after density-gradient centrifugation shows a typical titer-profil for every time of immunization status: beginning with traces of IgM-antibody - when the HAI-test of the uncentrifugated serum may be less than 1:10 - until 10 weeks after infection when only IgG-antibody will be detectable. The greatest amount of IgM-antibody is found in the 2. to 4. week after the rash.

A 4-year-old girl with neonatal onset of chronic diffuse urticarial rash, head enlargement, protruding eye balls, bilateral arthritis of the knees, growth and mental retardation, and signs in blood and cerebrospinal fluid of chronic inflammation is presented and compared to two similar cases reported by us previously. Including this new patient there are now 14 documented cases with this specific inflammatory syndrome whose aetiology remains unknown. In the present case, however, elevated antibody titres against I.ric. Borrelia antigen were found in the serum.

In 1814, George Maton, first recognized that a mild illness characterized by rash, adenopathy, and little or no fever was a discrete entity. Henry Veale, in 1866, named the disease rubella. The illness attracted little attention until 1942, when Norman Gregg noticed that first-trimester maternal rubella caused serious birth defects. The full spectrum and impact of rubella embryopathy remained unclarified until rubella virus was isolated in tissue culture in 1962 by two independent groups: Parkman, Buescher, and Artenstein; and Neva and Weller. Using the new tools of the virus laboratory, many investigators concentrated on the consequences of a severe rubella epidemic in 1964, which affected approximately 1% of pregnancies. Newly recognized transient manifestations of congenital rubella infection (CRI) include neonatal thrombocytopenic purpura, hepatitis, bone lesions, and meningoencephalitis and late-emerging sequelae such as diabetes mellitus and progressive rubella panencephalitis added to the cataract, heart disease, mental retardation, and deafness previously defined as due to CRI. Sharp contrasts were documented between the patterns of virus excretion and immune response of postnatal vs. congenital rubella. Licensure and widespread distribution of attenuated rubella virus vaccines in 1969 have prevented epidemic rubella. Pockets of illness remain, even in the United States. Continued effort will be required to eliminate the rubella problem.

Some viruses, such as rubella and human cytomegalovirus, are known to cross the placental barrier and infect the fetus. In other cases of maternal viral infections, such as herpes simplex, evidence for transplacental passage is less convincing and fetal damage or neonatal disease may be coincidental or associated with perinatal infection. Certain cases of fetal or neonatal disease following maternal viral infections may be associated with disease in the mother which affects her metabolic processes or the placenta in such a way as to interfere with development of the fetus and infant. The possible effects of transplacental viral infections are several. Fetal loss may occur by means of abortion or stillbirth. There may be infection of the fetus, with clinical manifestations such as rash, or without clinical manifestations. The infant may be born with congenital defects, including such deformities as cataracts, cardiac anomalies, mental retardation or cerebral palsy. Although a number of maternal viral diseases have been etiologically incriminated in congenital defects, only two-rubella and cytomegalovirus infection-are definitely proved to be associated with anomalies or mental retardation in infants.

Three unrelated children (one girl and two boys) have had since birth a syndrome characterized by a permanent skin rash which becomes more intense during flare-ups associated with fever, lymphadenopathy, splenomegaly, and arthritis symmetrically involving the large joints. In one boy, typical psoriasis was observed at age 3 years. In two patients, roentgenograms of the joints showed early patellar ossification and an abnormal epiphyseal appearance. The three children also had neurologic involvement, with mental retardation, enlarged head circumference, eye lesions, late closure of the anterior fontanel, and a chronic meningitis with infiltration by polymorphonuclear cells. No immunologic abnormalities were found, but polymorphonuclear cells infiltrated the skin, lymph nodes, synovial fluid, and CSF.

A new neuroectodermal syndrome (designated CHIME syndrome) was described in 1983 with a total of four patients reported, it is presumed to be an autosomal recessive disorder because of recurrence in sibs. The main features include ocular colobomas, congenital heart disease, early onset migratory ichthyosiform dermatosis, mental retardation, conductive hearing loss, seizures, and typical facial features. We report a fifth child with the condition, confirming the unique nature of the condition. Long term follow up information on this patient, as well as the previously described cases, provides information regarding the outcome for these patients, which includes general good health, severe mental retardation, seizures that worsen after puberty, conductive hearing loss, and chronic migratory ichthyosiform skin rash without scarring.

Children of parents with intellectual disabilities (i.e., IQs less than 80, labeled as having mental retardation) are at risk for neglect due to inadequate parenting abilities. Previous studies have shown that these parents are responsive to parent-training packages consisting of instructions, pictorial cues, modeling, feedback, and reinforcement. This study evaluated the effectiveness of self-learning pictorial-parenting manuals in teaching basic child-care skills (diapering, treating diaper rash, bathing, safety) to parents with intellectual disabilities who are monitored by child protection agencies. The manuals alone increased child-care skills (to levels seen in parents without disabilities) in 9 out of the 10 mothers in the study and in 12 of 13 child-care skills. The remaining skill was acquired with the full training package. Follow-up indicated that the acquired skills were maintained for up to 3 years. Mean correct performance with the manual was positively correlated with the trainer's rating of the mother's reading level and acceptance of the manual when the mother was first given the manual. Consumer satisfaction ratings of the manuals were high. These results indicate that many parents with intellectual disabilities may improve their child-care skills without intensive training and that self-instruction may be an easily disseminable and cost-effective way of reducing the risk of child neglect due to parenting skill deficiencies.

Childhood tuberculous meningitis is associated with serious long-term sequelae, including mental retardation, behavior disturbances, and motor handicap. Brain damage in tuberculous meningitis results from a cytokine-mediated inflammatory response, which causes vasculitis and obstructive hydrocephalus. Thalidomide, a potent tumor necrosis factor alpha inhibitor, was well tolerated and possibly showed some clinical benefit in children with tuberculous meningitis during a pilot study. The purpose of the present study was to assess the effect of adjunctive thalidomide in addition to standard antituberculosis and corticosteroid therapy on the outcome of tuberculous meningitis. Thalidomide (24 mg/kg/day orally) or placebo was administered in a double-blind randomized fashion for 1 month to patients with stage 2 or 3 tuberculous meningitis. The study was terminated early because all adverse events and deaths occurred in one arm of the study (thalidomide group). Thirty of the 47 children enrolled received adjunctive thalidomide, of whom 6 (20%) developed a skin rash, 8 (26%) hepatitis, and 2 (6%) neutropenia or thrombocytopenia. Four deaths (13%) occurred in patients with very severe neurologic compromise at baseline; two deaths were associated with a rash. Motor outcome after 6 months of antituberculosis therapy was similar in the two groups, even though the thalidomide group showed greater neurologic compromise on admission. In addition, the mean IQ of the two treatment groups did not differ significantly (mean IQ thalidomide group 57.8 versus mean IQ control group 67.5; P = .16). These results do not support the use of adjunctive high-dose thalidomide therapy in the treatment of tuberculous meningitis.

Rubella, also known as German measles, is usually a very mild infection that can have devastating effects in certain instances. It is a pleomorphic RNA virus in the Togaviridae family of the genus Rubivirus. It typically causes a scarletiniform rash, cervical lymphadenopathy, and mild constitutional symptoms, but in older children and adults, especially women, it may be more severe, with joint involvement and purpuric rash. Infection during the first 12 weeks of pregnancy results in congenital infection and/or miscarriage in 80-90% of cases. The congenital rubella syndrome (CRS) involves multiple organ systems and has a long period of active infection and virus shedding in the postnatal period. For these reasons, the rubella vaccine program was instituted in 1969, and the incidence of rubella infection in the United States has since declined by 99%. Rubella has been recognized as a disease for approximately 200 years, and it has since been found that humans are the only natural reservoir for the rubella virus. Virus is present in nasopharyngeal secretions, blood, feces, and urine during the clinical illness, although patients with subclinical disease are also infectious. The virus is spread via oral droplets and is shed in the nasopharynx for approximately 7 days before and after the rash is visible. CRS includes a configuration of anomalies, including nerve deafness, cataracts, cardiac anomalies (usually pulmonary artery and valvular stenosis, and patent ductus arteriosis), and mental retardation, with late complications including diabetes, thyroid disease, growth hormone deficiency, and progressive panencephalitis. In 1969, the first rubella vaccine was licensed for use, and the Centers for Disease Control and Prevention (CDC) began its National Congenital Rubella Syndrome Registry. As required under the National Childhood Injury Act, all healthcare providers in the United States who administer any vaccine shall, prior to administration of the vaccine, provide a copy of the Vaccine Information Statements (VIS) produced by the CDC to the parent or legal representative of any child to whom the provider intends to administer such vaccine, or to any adult to whom the provider intends to administer such vaccine. Despite efforts to vaccinate children, CRS continues to occur in the United States. Hispanic infants have an increased risk of CRS. HIV-1infected children with a preserved immune system and MMR immunization had a good response to rubella vaccine. In contrast, those in more advanced categories for HIV infection responded poorly. Issues of risk, choice, and chance are central to the controversy over the MMR vaccine that erupted in the UK in 1998, and has continued into the new millennium. An important contribution to the MMR controversy has come from the parents of autistic children, some of whom reject the notion that this disorder is a random genetic misfortune and insist that it is, at least in part, the result of some environmental insult, such as MMR vaccinations.

The objective of this case control study was no identify the possible associated risk factors of mild mental retardation in children. Sixty-nine parents of mildly mentally retarded (MR group) male children and a similar number of matched parents of normal male children (control) were interviewed using a questionnaire. The MR group was found to belong to the middle and the lower socioeconomic classes. Histories of maternal smoking, skin rash, fever, and less attendance to antenatal clinics during pregnancy were reported significantly more by mothers of the MR group (P = 0.027, 0.008, 0.027 and 0.0018, respectively). Furthermore, these mothers reported more collective occurrence of newborn jaundice, fever, convulsions, incubator need, and head trauma (P = 0.004). More consanguineous marriages were found in the control group (73.9%) as compared to the MR group (59.4%) (P = 0.056). A family history of mental retardation was, however, more in the latter group compared to the former group (P=0.027). The risk of having another mentally retarded member in the family was found to be a higher if the familial degree of another closeness to the mentally retarded member was more. Well planned health education programs, genetic counseling units, and sufficient antenatal and neonatal services are of prime importance.
