143 people treated for tick-borne encephalitis (TBE) were included in a retrospective follow-up study. Sequelae and epidemiological characteristics in 114 individuals were analysed. The case fatality rate and the prevalence of residual paresis were low, 1.4 and 2.7%, respectively. However, 40 (35.7%) individuals were found to have a postencephalitic syndrome after a median follow-up time of 47 months, and a majority (77.5%) of these were classified as moderate to severe. Various mental disorders, balance and co-ordination disorders and headache were the most frequently reported symptoms. Increasing age was correlated to a longer duration of hospital stay, longer convalescence and increased risk of permanent sequelae. Results from a neuropsychiatric questionnaire showed marked differences between the subjects with sequelae compared to controls. 57% had noticed a tick bite before admission, and 48% were aware of at least one person in their environment who previously had contracted TBE. 79% were permanent residents or visited endemic areas often and regularly. In conclusion, we have found that TBE in the Stockholm area has a low case fatality rate, but gives rise to a considerable number of different neurological and mental sequelae, which justifies vaccination of a defined risk population in endemic areas.
The prognosis of allergic rhinitis was studied in 154 children aged 3-17 years at diagnosis by means of a detailed questionnaire administered 8-11 years later. The symptoms had completely disappeared in only 15 (10%) patients. The conjunctival symptoms, however, had disappeared or were controlled successfully by topical drug therapy in almost all, and 77 (50%) were managing without medication for allergic rhinitis. Twenty-five (23%) of the 110 children with seasonal allergic rhinitis had a perennial disease at follow-up, in contrast to seven (16%) of 44 with perennial allergic rhinitis originally who had only seasonal symptoms at follow-up. Asthma or wheezing had developed in 29 cases (19%) and was more common (p less than 0.01) among those with perennial allergic rhinitis (15 of 44) than among those with seasonal allergic rhinitis (14 of 110). No significant association was found between age at onset of symptoms, family history of atopic disease or type of treatment for allergic rhinitis and allergic rhinitis still present at follow-up or development of asthma during the observation period.
13C-urease breath tests have been extensively used in world-wide gastroenterological practice since the 1990s. We have been using them since 2000, but their clinical application in Russia is far from being universal. Moreover, their results are significantly different from those obtained by other methods for determining H. pylori. The authors report original data on the peculiarities of occurrence of this pathogen in its carriers.
During 1981-1993, 229 episodes of bacteraemia due to beta-haemolytic streptococci of groups A, B, C and G were diagnosed in the County of Northern Jutland, Denmark. The annual rates for bacteraemia were quite constant during the 13-year period for each streptococcal group. Group A streptococcal (GAS) bacteraemia was the most frequent, comprising 1.4% of all bacteraemias. The incidence of GAS bacteraemia was 1.8/100,000/year in children 60 years old. With the notable exception of group B streptococcal (GBS) bacteraemia in neonates, beta-haemolytic streptococci of groups B, C (GCS) and G (GGS) were isolated mostly from elderly patients. Except for GBS bacteraemia in neonates, approximately one-third of the bacteraemias in each group was nosocomially acquired. Predisposing factors included operative procedures in GAS and GCS bacteraemia, and diabetes mellitus in GBS bacteraemia. The skin was the most common primary focus in GAC, GCC and GGS bacteraemias, whereas the urinary tract was the commonest focus in GBS bacteraemia in adults. The mortality rates in GAS, GCS, GGS, and adult GBS bacteraemia were 23%, 16%, 17% and 19%, respectively. Of the 23 fatal cases of GAS bacteraemia, 57% died within 24 h after blood cultures had been obtained.
The 16-year incidence, progression and regression of diabetic retinopathy in a young population-based Danish cohort with type 1 diabetes mellitus: The Danish cohort of pediatric diabetes 1987 (DCPD1987).
The aim was to investigate the long-term incidence of proliferative diabetic retinopathy (PDR), and progression and regression of diabetic retinopathy (DR) and associated risk factors in young Danish patients with Type 1 diabetes mellitus. In 1987-89, a pediatric cohort involving approximately 75 % of all children with Type 1 diabetes in Denmark
Results of standard patch tests performed with the same methodology in one centre are rarely available over a large time span. This gives the unique opportunity to study not only prevalence but also persistency of contact allergy and characterize subpopulations. The objectives were to investigate sensitivity rates and persistencies of patch test results and characterize patients with multiple contact allergies. A 20-year retrospective database-based study of 14 998 patients patch tested with the European Standard Series was performed. 34.5% were sensitized, primarily women. Sensitivity to nickel was most frequent and least frequent to mercaptobenzothiazole, N-isopropyl-N-phenyl-p-phenylenediamine and benzocaine. Yearly proportion of negative, mono/double-allergic, and multiple-allergic cases remained stable. Persistency of positive reactions was high for para-phenylenediamine, Cl(Me)isothiazolinone, and primin and poor for paraben mix. 5.1% were multiple allergic, primarily women, and 90% got diagnosed by the first test. Frequency of multiple allergies increased with age. More multiple- than mono/double-allergic patients were tested multiple times. Persistency and sensitivity rates in a Danish eczema population are provided and are useful for decisions regarding the standard series. Patients with multiple contact allergies are typically elderly women who might have long-lasting and hard-to-treat eczema. Cumulative environmental exposure seems necessary to develop multiple allergies.
BACKGROUND: The intention of this study was to increase the knowledge concerning the rehabilitation of women with drug problems after the birth of a child and to find out how the children developed. MATERIAL AND METHODS: A follow-up study of 31 women, former drug and alcohol abusers and their children, 19 girls and 12 boys born in 1982-1983. The first survey took place when the children were 2-3 years of age, then when they were 7-9 and at last when they were 15-17. The biological mothers, foster or adoptive mothers, the children and their teachers were interviewed. RESULTS: The women got more support and control during the pregnancy than afterwards. Most of the mothers became single. Women with the shortest drug history, a good social network and a stable partner without drug problems kept the care of their children. By the first survey (1985), seven children had been placed in foster homes, in the second (1992) two further children had been taken away from their mothers, and in the third (1999) only one third of the children were living with their biological mothers. Most of the children did well at school and in their families, had friends and leisure activities despite still living by their mothers or in foster/adoption homes. None of the youngsters had been in conflict with the law or were drug abusers, but every second teenage girl needed psychological support. Children who had been stable by their drug-free biological mothers functioned best. INTERPRETATION: Mothers with drug problems do not get sufficient attention after the delivery and when the children grow up. A supporting family should be brought in contact with mother and child after the delivery. Under special circumstances pregnancy can be a positive turning point for women with drug problems.
