Rate and predictability of pulp revascularization in therapeutically reimplanted permanent incisors

Abstract The aim of the present investigation was to study the frequency of pulp revascularization in therapeutically reimplanted incisors as well; is its relationship with the following factors: width of apical foramen, duration of extra-alveolar lime, storage conditions and postoperative administration of antibiotics. Out of 72 immature teeth (width of apical foramen 1.1–5.0 mm) the pulp was revascularized in 13 (18%), while in 88 mature teeth (width of apical foramen 1.0 mm or less) no revascularization occurred. Among parameters tested statistically in immature teeth, a significantly increased frequency of revascularization (p < 0.05) was only found in teeth reimplanted within 45 minutes after avulsion, when compared with teeth reimplanted after a longer extra-alveolar time, and in mandibular incisors when compared with maxillary incisors (p < 0.01). All teeth in which revascularization did not occur exhibited a periapical radiolucency and/or external inflammatory root resorption.     

Unilateral neglect: further validation of the baking tray task.

OBJECTIVE: The Baking Tray Task is a comprehensible, simple-to-perform test for use in assessing unilateral neglect. The aim of this study was to validate further its use with stroke patients. METHODS: The Baking Tray Task was compared with 2 versions of the Behaviour Inattention Test and a test for personal neglect. A total of 270 patients were subjected to a 3-item version of the Behaviour Inattention Test and 40 patients were subjected to an 8-item version of the Behaviour Inattention Test, besides the Baking Tray Task and the personal neglect test. RESULTS: The Baking Tray Task was more sensitive than the 3-item Behaviour Inattention Test, but the 8-item Behaviour Inattention Test was more sensitive than the Baking Tray Task. The best combination of any 3 tests was Baking Tray Task, Reading an article, and Figure copying; the 2 last-mentioned being a part of the 8-item Behaviour Inattention Test. CONCLUSION: Multi-item tests detect more cases of neglect than do single tests. However, it is tiresome for the patient to undergo a larger test battery than necessary. It is also time-consuming for the staff. Behavioural tests seem more appropriate when assessing neglect. The Baking Tray Task seems to be one of the most sensitive single tests, but its sensitivity can be further enhanced when it is used in combination with other tests.     

What Factors in Early Pregnancy Indicate that the Mother Will Be Hit by Her Partner during the Year after Childbirth?A Nationwide Swedish Survey

Abstract: Background : To be hit by one's intimate partner during the first year after childbirth may affect a woman's health and ability to take care of her newborn. The purpose of this study was to document the prevalence and indicators in early pregnancy of a woman being hit by her partner during the year after childbirth. Method : Information was collected by a postal questionnaire in early pregnancy and 12 months after childbirth from the approximately 5,550 women in Sweden who visited an antenatal care clinic for the first time during one of three chosen weeks in 1999 and 2000. Results : Of the 3,266 recruited women, 2,563 returned the follow‐up questionnaire. Being hit during the first year after childbirth was reported by 52 of the 2,563 (2%) women: 32 (61%) had been hit by their partner once, 12 (23%) twice, and 8 (15%) three or more times. Risk increased in women who were age 24 years or younger (3.9% had been hit), unmarried (7.1%), born in countries outside Europe (6.8%), with a partner born outside Europe (5.4%), had a low level of education (8.9%), and were unemployed (5.0%). In early pregnancy, women with back pain (4.0%), a chronic illness (4.1%), coital pain (6.1%), frequent depression‐related symptoms (8.1%), stomach pain (3.8%), or a urinary tract problem (6.3%) were hit more often than others after childbirth. Conclusions : At least 2 percent of Swedish women giving birth in 2000 were hit by their partner during the year after childbirth. Using identified predictors during antenatal care may increase the likelihood of finding women at risk, thereby enhancing the possibility of interventions to prevent this crime and health hazard.     

High rate of transfer of Staphylococcus aureus from parental skin to infant gut flora

Many Swedish infants carry Staphylococcus aureus in their intestinal microflora. The source of this colonization was investigated in 50 families. Infantile S. aureus strains were isolated from rectal swabs and stool samples at 3 days and at 1, 2, 4, and 8 weeks of age. The strains were identified by using the random amplified polymorphic DNA method and compared to strains from swab cultures of the mothers' hands, nipples, and nares and from the fathers' hands and nares. Maternal stool samples were also obtained at a later stage to compare infant and adult intestinal S. aureus colonization. Although 60% of 1-month-old children had S. aureus in the stools, this was true of only 24% of the mothers. The median population numbers in colonized individuals also differed: 10(6.8) CFU/g of feces among infants at 2 weeks of age versus 10(3.2) CFU/g of feces in the mothers. Of S. aureus strains in the stools of 3-day-old infants, 90% were identical to a parental skin strain. A total of 96% of infants whose parents were S. aureus skin carriers had S. aureus in their feces and 91% had the same strain as at least one of the parents. In comparison, only 37% of infants to S. aureus-negative parents had S. aureus in the stool samples. Thus, infantile intestinal S. aureus colonization was strongly associated with parental skin S. aureus carriage (P = 0.0001). These results suggest that S. aureus on parental skin establish readily in the infantile gut, perhaps due to poor competition from other gut bacteria.     

Is MED13L-related intellectual disability a recognizable syndrome?

Introduction

MED13L-related intellectual disability is characterized by moderate intellectual disability (ID), speech impairment, and dysmorphic facial features. We present 8 patients with MED13L-related intellectual disability and review the literature for phenotypical and genetic aspects of previously described patients.

Fast Eating Is Associated with Increased BMI among High-School Students

Fast self-reported eating rate (SRER) has been associated with increased adiposity in children and adults. No studies have been conducted among high-school students, and SRER has not been validated vs. objective eating rate (OBER) in such populations. The objectives were to investigate (among high-school student populations) the association between OBER and BMI z-scores (BMIz), the validity of SRER vs. OBER, and potential differences in BMIz between SRER categories. Three studies were conducted. Study 1 included 116 Swedish students (mean ± SD age: 16.5 ± 0.8, 59% females) who were eating school lunch. Food intake and meal duration were objectively recorded, and OBER was calculated. Additionally, students provided SRER. Study 2 included students (n = 50, mean ± SD age: 16.7 ± 0.6, 58% females) from Study 1 who ate another objectively recorded school lunch. Study 3 included 1832 high-school students (mean ± SD age: 15.8 ± 0.9, 51% females) from Sweden (n = 748) and Greece (n = 1084) who provided SRER. In Study 1, students with BMIz ≥ 0 had faster OBER vs. students with BMIz < 0 (mean difference: +7.7 g/min or +27%, p = 0.012), while students with fast SRER had higher OBER vs. students with slow SRER (mean difference: +13.7 g/min or +56%, p = 0.001). However, there was “minimal” agreement between SRER and OBER categories (κ = 0.31, p < 0.001). In Study 2, OBER during lunch 1 had a “large” correlation with OBER during lunch 2 (r = 0.75, p < 0.001). In Study 3, fast SRER students had higher BMIz vs. slow SRER students (mean difference: 0.37, p < 0.001). Similar observations were found among both Swedish and Greek students. For the first time in high-school students, we confirm the association between fast eating and increased adiposity. Our validation analysis suggests that SRER could be used as a proxy for OBER in studies with large sample sizes on a group level. With smaller samples, OBER should be used instead. To assess eating rate on an individual level, OBER can be used while SRER should be avoided.     

Different dose regimens of the mouse monoclonal-antibody 17-1a for therapy of patients with metastatic colorectal-carcinoma

Seventy-one patients with metastatic colorectal carcinoma(CRC) were treated with varying doses of the mouse monoclonal antibody (MAb) 17-1A. One patient achieved a partial remission (PR) (1%) with a survival duration of 114+ months. Further 10 patients showed a minor response (MR) or stable disease > 3 months (SD) (14%). In patients receiving a total dose of MAb17-1A < 2 g the overall response rate was 22% (10/45) (1 PR, 2 MR, 7 SD) while patients treated with a total dose > 2 g had a corresponding figure of 4% (1/26) (1 MR) (p < 0.05). Responding patients (n = 11) survived significantly longer than non-responding patients (n = 60) (median: 20 vs 10 months) (p < 0.0027). In the most intensive treatment group (total 12 g), 14 patients received 500 mg of MAb17-1A tiw for 8 weeks. The frequency and intensity of side-effects were mild and did not cause withdrawal or dose reduction of MAb17-1A, even in the 12 g dose schedule. Patients with a pretreatment ADCC (antibody dependent cellular cytotoxicity) activity above the median of all patients, survived significantly longer than those with a low value (p < 0.05).     

Diagnostic outcome of repeated mammography screening

Mammographic screening for breast cancer within health service routines was evaluated for the years 1987–1992, with special focus on repeated screening during 1989–1992. The overall attendance rate by women aged 40 to 74 years was 82.8%. During 1989–1992 malignancy was found in 2.6/1000 screened women, giving a 87.4% positive predictive rate at surgery and 95.9% efficiency. Among women aged 45, the positive predictive rate was >94%. Fine-needle aspiration (FNA) biopsy showed invasive cancers in 84% and highly suspected cancer in another 15%; 60% of the lesions were nonpalpable. For first-time (prevalence) screening (1987–1988) the positive predictive rate was 86% and the malignancy yield 6.4/1000. In women aged 40–44 years there were few surgical referrals (1.6%), but the positive predictive rate at surgery was only 48.3%, indicating diagnostic difficulties in young women. The median size of all invasive cancers was 12 mm: 84% were classified as pT1, and 23% had lymph node involvement. Stage II disease was found in 27% of all malignancies. The use of FNA in the diagnostic workup for breast cancer screening is of crucial importance to the maintenance of high positive predictive rates at surgery. Moreover, regular analysis is important even when mammographic screening is incorporated into the routine work of health services.

Resumen El tamizaje mamográfico para cáncer del seno como parte de las rutinas de los servicios de salud fue evaluado para los años 1987–1992, con especial énfasis en el tamizaje repetido en el período 1989–1992. La tasa de cumplimiento por parte de las pacientes en las edades 40–74 años fue de 82.8%. En 1989–92 se halló neoplasia maligna en 2.6/1000 mujeres tamizadas, lo cual significó un índice de predicción de positividad en la cirugía de 87.4% y de eficiencia de 95.9%. Entre las mujeres con edad 45 años el valor de predicción de positividad fue >94%. La biopsia por aspiración con aguja fina demostró cánceres invasores en 84% y alta sospecha de cáncer en un 15% adicional; 60% de las lesiones fueron no palpables. En el tamizaje de primera vez (prevalencia, 1987–1988) el valor de predicción de positividad fue de 86% y el rendimiento de 6.4/1000. En las mujeres con edades 40–44 años se hicieron menos referencias para cirugía (1.6%) pero el valor de predicción de positividad en la cirugía fue apenas de 48.3%, lo cual indica dificultades diagnósticas en las pacientes más jóvenes. El tamaño promedio de los cánceres invasores fue 12 mm; 84% fueron clasificados como pT1 y 25% presentaban invasión ganglionar; 27% de todos los tumores malignos fueron estado II. La aspiración con aguja fina en la evaluación diagnóstica del tamizaje para cáncer mamario es de importancia crucial para el mantenimiento de un alto valor de predicción de positividad en la cirugía y el análisis regular es importante aun cuando el tamizaje mamográfico quede incorporado en el trabajo rutinario de los servicios de salud.

Résumé Le dépistage systématique des cancers du sein par mammographie effectuée par les services de santé a été évalué entre 1987–1992, en particulier le dépistage répété pratiqué entre 1989–1992. Le taux de participation des femmes âgées entre 40–74 ans a été de 82.8%. Dans la période 1989–1992, une tumeur maligne a été retrouvée chez 2.6/1000 femmes, la chirurgie permettant de calculer une valeur prédictive positive de 87.4% et une efficacité de 95.9%. Chez les femmes âgées de plus de 45 ans, la valeur prédictive positive a dépassé 94%. La ponction biopsie a fourni la preuve de cancer invasif dans 84% des cas et celle d'une forte suspicion dans 15% des cas, alors que 60% des lésions n'étaient pas palpables. Par comparaison, la valeur prédictive positive pendant la période de dépistage entre 1987–88 a été de 96% pour une prévalence de cancer de 6.4/1000. Chez la femme âgée entre 40–44 ans, très peu de femmes ont été opérées, avec une valeur prédictive positive de 48.3%, ce qui démontre les difficultés de diagnostic chez la femme jeune. La taille médiane de tous les cancers invasifs était de 12 mm: 84% étaient classés comme pT1 et 23% avaient un envahissement lymphatique. On a trouvé un stade II chez 27% des patientes tous cancers confondus. L'utilisation de ponction biopsie est capitale pour le diagnostic de cancer de sein pour maintenir une valeur prédictive positive élevée lors de la chirurgie et une analyse régulière est nécessaire même lorsque le dépistage systématique par mammographie est inclu dans le programme des service de santé.

     

Parents’ experiences of an instrumental vaginal birth findings from a regional survey in Sweden

ObjectiveAn instrumental vaginal birth is known to affect women’s birth experience, few studies have explored the fathers’ experiences of attending such a birth. The aim of this study is to compare birth outcome and parents’ feelings in parents with instrumental vaginal birth or a spontaneous vaginal birth.MethodsA regional survey was conducted of 936 mothers and 827 fathers recruited in mid-pregnancy and followed up 2 months after birth. Data was collected by questionnaires. Crude and adjusted odds ratios with a 95% confidence interval were used in the analysis.ResultsThe prevalence for instrumental vaginal birth was 9%. Prolonged labour (OR 8.3; 95% CI 5.0–13.9), augmentation with synthetic oxytocin (OR 5.1; 2.9–8.9), and birth complications (OR 2.5; 1.5–2.6) were more common in the instrumental vaginal group. An instrumental vaginal birth was associated with a negative birth experience for mothers (OR 3.2; 1.3–8.1) and fathers (OR 5.2; 1.2–21.5). Mothers who had an instrumental vaginal birth were more likely to report feelings that the baby would be damaged during birth (OR 3.0; 1.7–5.5) and that the birth experience made them decide not to have any more children (OR 3.4; 1.1–10.7). Fathers reported a near-panic feeling when attending an instrumental vaginal birth (OR 5.2; 1.7–15.5).ConclusionAn instrumental vaginal birth was correlated with longer and more complicated births, epidurals and oxytocin augmentation. It affected the birth outcome and parents’ feelings and was associated with future reproductive thoughts and a negative birth experience.     

Fathers want to stay close to their partner and new baby in the early postnatal period: The importance of being able to room in after a surgical birth

The early postnatal period can be challenging for new fathers especially when their partner has experienced a caesarean section. The aim of this study was to describe men’s perceptions and feelings of staying with their partner and new baby in the context of having experienced a surgical birth. Thematic analysis was employed to analyse telephone interviews collected from 21 Swedish fathers who had experienced elective or emergency caesarean section. Being involved, receiving support and providing support were main reasons men considered it important they be facilitated to stay with their partners. Postnatal care should be oriented towards the whole family.
