Background Treatment of drinking water may decrease microbial exposure. Objective To investigate whether bacterial load in drinking water is associated with altered risk of allergic diseases. Methods We recruited 1,110 schoolchildren aged 6‐16 years between 2011 and 2013 in Požega‐Slavonia County in Croatia, where we capitalized on a natural experiment whereby individuals receive drinking water through public mains supply or individual wells. We obtained data on microbial content of drinking water for all participants; 585 children were randomly selected for more detailed assessments, including skin prick testing. Since water supply was highly correlated with rural residence, we compared clinical outcomes across four groups (Rural/Individual, Rural/Public, Urban/Individual and Urban/Public). For each child, we derived quantitative index of microbial exposure (bacterial load in the drinking water measured during the child's first year of life). Results Cumulative bacterial load in drinking water was higher (median [IQR]: 6390 [4190‐9550] vs 0 [0‐0]; P < .0001), and lifetime prevalence of allergic diseases was significantly lower among children with individual supply (5.5% vs 2.3%, P = .01; 14.4% vs 6.7%, P < .001; 25.2% vs 15.1%, P < .001; asthma, atopic dermatitis [AD] and rhinitis, respectively). Compared with the reference group (Urban/Public), there was a significant reduction in the risk of ever asthma, AD and rhinitis amongst rural children with individual supply: OR [95% CI]: 0.14 [0.03,0.67], P = .013; 0.20 [0.09,0.43], P < .001; 0.17 [0.10,0.32], P < .001. Protection was also observed in the Rural/Public group, but the effect was consistently highest among Rural/Individual children. In the quantitative analysis, the risk of allergic diseases decreased significantly with increasing bacterial load in drinking water in the first year of life (0.79 [0.70,0.88], P < .001; 0.90 [0.83,0.99], P = .025; 0.80 [0.74,0.86], P < .001; current wheeze, AD and rhinitis). Conclusions and Clinical Relevance High commensal bacterial content in drinking water may protect against allergic diseases.
Bursae around the knee reduce friction between moving structures. When involution of suprapatellar septum fails to occur ("complete septum"), then suprapatellar bursa may stay completely separated from the knee joint cavity to form a cystic cavity. In the case of the increased volume, suprapatellar bursitis can cause painful suprapatellar swelling. The aim is to point to the possibility of arthroscopic decompression of suprapatellar cyst. In the case presented, the indication for knee arthroscopy was based on clinical examination, ultrasonography and magnetic resonance studies. The preoperative diagnosis was verified intra-operatively, and intra-articular cyst decompression was performed by arthroscopy. At the final examination 8 months postoperatively, the patient still had no pain, swelling and had full range of motion. This minimally invasive operative procedure resulted in a satisfactory anatomic and functional outcome. In this case report, we present a patient with suprapatellar cyst submitted to arthroscopic cyst decompression.
Background: Respiratory syncytial virus (RSV) stimulates the production of specific immunoglobulin (Ig) E and IgG4 antibodies as a hallmark of the Th2 immune response. In this paper, we evaluated the occurrence of atopic diseases in 10-year-old children who were positive for RSV-specific IgG antibodies during infancy. Methods: The prospective follow-up of 72 children included a physical examination, an International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire and the determination of RSV-specific antibodies and total and allergen-specific IgE. Results: Children with asthma had their first wheezing episode at a younger age (χ2 8.097, df = 1, p = 0.004). RSV-specific IgG4 levels at year one were positively correlated with atopic dermatitis (AD) (tau_b = 0.211, p = 0.049) and current AD (tau_b = 0.269, p = 0.012); and RSV-specific IgE levels were positively correlated with allergic rhinitis (AR) (tau_b = 0.290, p = 0.012) and current AR (tau_b = 0.260, p = 0.025). Positive RSV-specific IgE at the age of one increased the chances of asthma occurrence by 5.94 (OR = 5.94, 95% CI = 1.05–33.64; p = 0.044) and the chances of AR by more than 15 times (OR = 15.03, 95% CI = 2.08–108.72; p = 0.007). A positive family history of atopy increased the chances of asthma occurrence by 5.49 times (OR = 5.49, 95% CI = 1.01–30.07; p = 0.049), and a longer duration of exclusive breastfeeding lowered that chance (OR = 0.63, 95% CI = 0.45–0.89; p = 0.008). Prenatal smoking increased the chances of AR occurrence by 7.63 times (OR = 7.63, 95% CI = 1.59–36.53; p = 0.011). Conclusion: RSV-specific IgE and RSV-specific IgG4 antibodies could be risk markers for the development of atopic diseases in children.
NS associated with c.153delT are particularly severe as demonstrated in our patient.Testing of both parents was recommended as each parent of a child with autosomal recessive disease is generally considered to carry at least one copy of an aberrant allele. We found that her father has a pathogenic variant 153delT], p. (Gln52LysfsTer6), while her mother has no pathogenic variants. Genetic counseling emphasized that the genetic finding in our patient was not due to uniparental disomy and that the likely cause is de novo mutation in the maternal germinal cell. Although no specific treatment is available for Netherton syndrome, the first year of life has to be carefully managed, with rigorous care procedures that include multidisciplinary care. This approach should include careful monitoring and treatment of infections and hypernatremia, individual recommendations for calorie and protein needs for adequate growth, careful monitoring of allergic sensitization and dietary advice to optimise their nutritional intake, local skin treatment and supportive immunoglobulin therapy.Following introduction of immunoglobulins, the patient had no infections during 2-years follow-up. However, despite intensive and individualized dietetic approach and nutritional treatment, our patient is still severely malnourished (WHO zscore: weight-for-age -2.49; lenght-for-age: -1.29; weight-forlength: -2.5).
