RESUMO

Introduction This study is a systematic review on recent developments about the importance of HMGB1 protein in the pathogenesis of rhino-sinusal inflammatory diseases. We also report data on the use of 18-ß-glycyrrhetic acid (GA), which has been shown able to inhibit the pro-inflammatory activities of HMGB1, in young patients affected by allergic rhinitis and complaining of nasal obstruction as main symptom. Objectives The objective of this study was to review the literature to demonstrate the importance of HMGB1 in the pathogenesis of nasal inflammatory disorders and understand whether the inhibition of this protein may be an efficacious and innovative therapeutic strategy for patients with rhino-sinusal inflammation. Data Synthesis Authors searched for pertinent articles indexed in PubMed, Scopus, and other health journals between 2004 and 2015. In total, the authors gathered 258 articles: 219 articles through Pubmed and 39 articles from other search engines. The search terms used were as follows: HMGB1 AND "respiratory epithelium," "airway inflammation," "rhinitis," "allergic rhinitis," "rhinosinusitis," "nasal polyposis," "glycyrrhetic acid," "children." Conclusions Patients with severe symptoms have the highest serum levels and the highest extracellular expression of HMGB1. GA inhibits HMGB1 chemotactic and mitogenic function by a scavenger mechanism on extracellular HMGB1 accumulation stimulated by lipopolysaccharides in vitro. Treatment of allergic rhinitis with GA is not associated with local or systemic side effects in children and adults.

RESUMO

RATIONALE AND AIM: This paper has the object to present the impact of nuts' and seeds' injuries withdrawing data from the Susy Safe registry, highlighting that as for other foreign bodies the main item efficiently and substantially susceptible to changes to decrease the accidents' rates is the education of adults and children, that can be shared with parents both from pediatricians and general practitioners. Indeed labeling and age related warnings have also a fundamental relevance in prevention. METHODS: The present study draws its data from the Susy Safe registry. Details on injuries are entered in the Susy Safe Web-registry through a standardized case report form, that includes information regarding: children age and gender, features of the object, circumstances of injury (presence of parents and activity) and hospitalization's details (lasting, complications and removal details). Cases are prospectively collected using the Susy Safe system from 06/2005; moreover, also information regarding past consecutive cases available in each centre adhering to the project have been entered in the Susy Safe registry. RESULTS: Nuts and seeds are one of the most common food item retrieved in foreign bodies injuries in children. In Susy Safe registry they represent the 38% in food group, and almost the 10% in general cases. Trachea, bronchi and lungs were the main location of FB's retrieval, showing an incidence of 68%. Hospitalization occurred in 83% of cases, showing the major frequency for foreign bodies located in trachea. This location was also the principal site of complications, with a frequency of 68%. There were no significant associations between these outcomes and the age class of the children. The most common complications seen (22.4%) was bronchitis, followed by pneumonia (19.7%). Adult presence was recorded as positive in 71.2% of cases, showing an association (p value 0.009) between the adult supervision and the hospitalization outcome. On the contrary there was a non significant association between adult presence and the occurrence of complications. In 80.7% of cases, the incident happened while the child was eating. Among those cases, 88.6% interested trachea, lungs and bronchi. CONCLUSIONS: Food-related aspiration injuries are common events for young children, particularly under 4 years of age, and may lead to severe complication. There is a need to study in more depth specific characteristics of foreign bodies associated with increased hazard, such as size, shape, hardness or firmness, lubricity, pliability and elasticity, in order to better identify risky foods, and more precisely described the pathogenetic pathway. Parents are not adequately conscious and aware toward this risk; therefore, the number and severity of the injuries could be reduced by educating parents and children. Information about food safety should be included in all visits to pediatricians in order to make parents able to understand, select, and identify key characteristics of hazardous foods and better control the hazard level of various foods. Finally, preventive measures including warning labels on high-risk foods could be implemented.

RESUMO

RATIONALE AND AIM: Foreign bodies (FB) aspiration, ingestion, insertion or inhalation can be a serious occurrence, resulting in fatality if not promptly recognized and solved. The aim of the current paper is to present foreign body ingestion's cases observed at the Children's Hospital Gutierrez in Buenos Aires in 5 years of ORL activity and to compare main findings with data coming from other well known already published case series. METHODS: A prospective study was realized on children having ingested, inhaled, aspirated or introduced FBs, with regard to age and sex distribution, FB's type, dimensions and consistency, FB's location, clinical presentation, removal and occurrence of complications. RESULTS: FBs retrieved amounted to 2336 cases. The most common location was the nose (66.7%), where the most frequent FBs retrieved were inorganic (72.7%) and occurred in children younger than 3 years old (54.2%), the only position where children younger than 3 years are a majority in respect to the older ones. The presence of the adult was seen in the preponderance of cases (88.4%). Symptoms varied between the different anatomical systems, with cough as predominant when concerning aspiration, local pain or inflammation in inhalation and insertion, and vomiting in for the FBs ingestion cases. All the foreign bodies retrieved were clustered in categories, due to necessity when extremely various and with low absolute frequency. The most common FBs retrieved were pearls (20.2%), followed by stationery products (mostly rubbers) and coins. Complications had a low rate in all the studies. CONCLUSIONS: The study stresses the importance of primary prevention, seen as the active care of adults toward children manipulating foreign bodies potentially dangerous. This presence may not avoid the event, but in case of FBs aspiration, ingestion, insertion or inhalation, it could be the main factor leading to a faster and correct treatment. Prompt removal of the foreign body decreases the risk of complications, resulting in a lower length of hospitalization. Symptoms were various and differed in all the studies, showing that their wide amount indicates the importance of registries to early recognize and therefore treat a pathology that might be mistaken for something different due to unspecific signs. Secondary prevention with specific training of doctors on clinical post-trauma guidelines for treatment and active participation of doctors to the broadening of the current registries seem to be other ways for lowering the outburst of FBs injuries.

RESUMO

Even if foreign body (FB) insertion in the external auditory canal (EAC) is not an uncommon event, the literature based on large series is scarce. In the present study, ear FB cases observed at the Children's Hospital Gutierrez in Buenos Aires over five years of otorhinolaryngology (ORL) activity are presented, and the main findings are compared with data coming from other well-known published case series. Three hundred ninety-two injury cases were observed. Eighty percent of them occurred while the child was playing; in 328 cases (83.7%), adults were present. The retrieved FB included food items and objects usually available at home, such as pins, while fragments of toys were found in only 2 cases. These findings testify to the efficacy of regulations imposing manufacturing quality standards on toys; on the other hand, parents seem to be unaware of the risk imposed by FB insertion, since injuries usually happen under adult supervision while children are manipulating objects not adapted for their age.

RESUMO

OBJECTIVE: The analysis of foreign bodies (FB) injuries in the upper aero-digestive tract is not available for Ecuador and in this context, the present article represent the is the first presenting to the international community the basic epidemiological data on the Ecuador's experience on foreign bodies juries. METHODS: Data on 258 cases were gleaned using Susy Safe database, choosing the cases coming from Ecuador's institutions, namely Francisco De Icaza Bustamante Children Hospital, in Guayaquil (Ecuador) which collects data on children injuries due to foreign bodies with the aid of a standardized case report forms. RESULTS: Patients showed a female:male ratio of 1:1.2. Fifty-three percent of the children were younger than 2 years of age, with a mean age of 3.22 years. The most frequent location of retrieval was the oesophagus (37.98%) followed by the ears (34.88%). Coins were the most frequent cause of accident (37.21%). Seeds and grain were the most frequent food FBs and they were seen in 13.95% of cases. Adult presence was recorded in 113 cases. There was indeed a significant correlation between the presence of an adult and the activity that the children were doing when the incident occurred. CONCLUSIONS: This first breach into the analysis of injuries in Ecuador gives the confirmation that the results coming from country's data agreed with the general Susy Safe ones. Similar preventive strategies are therefore highly recommended, stressing that primary prevention has the main role in children's protection.

RESUMO

OBJECTIVE: The aim of the present paper is to present nasal foreign cases observed at the Children's Hospital Gutierrez in Buenos Aires, Argentina, over a 4-year period and to compare the main findings with data from other case series. METHODS: A prospective study was undertaken on children having inhaled/aspired a foreign body (FB), with regard to age and sex distribution, FB type, dimensions and consistency, FB location, clinical presentation, removal and occurrence of complications. RESULTS: A total of 1559 cases of foreign body inhalation were observed. The mean age of the children was 3.48 years (SD 1.60). Injuries frequently occurred during recreational activities: in 1154 cases (74.1%) the child was playing, while in 52 cases the accident occurred during a party. In 1417 cases (90.9%) adults were present. Children frequently (1123 cases) insert small objects with a rigid consistency in their noses, like pearls or little metal objects. In the majority of cases nasal FB injuries are due to insertion of inorganic objects (72.7%). CONCLUSION: Injuries are frequently due to the incorrect manipulation of objects not conceived for children use, including pins, nails, screws and floats. Batteries and magnets deserve particular mention because they require immediate treatment, as they can cause septal necrosis and perforation within hours. Unfortunately, an adult being present does not seem to be sufficient to prevent injuries, and parents are frequently unaware of the danger. The dissemination of information regarding safe behaviors could be fundamental in preventing injuries and need to be promoted by family pediatricians and health practitioners.

RESUMO

The ingestion of foreign bodies causing esophageal injuries is a common event, mostly in children's population. The aim of the present paper is to present foreign body (FB) ingestion cases observed in a five-year period at the Children's Hospital Gutierrez, Buenos Aires, Argentina and to compare the main findings with data coming from other well-known case series, already published in scientific literature. A prospective study on 320 of esophageal foreign body was carried out , with regard to age and sex distributions, type, dimensions and consistency, location, clinical presentation, removal and complications. In the majority of cases injuries happened while children were playing and in 85.3% adults were present. Children most frequently ingested coins (83.8% cases). Removal was performed in all cases under general anaesthesia, in 34 by esophageal forceps and in 286 cases by Magill hypopharyngeal forceps. Just one case showed complications, presenting esophageal perforation. The final results of this study show that injuries usually happen under adults' supervision and highlight that FBs involved in the incident belong to classes of objects not conceived for children's use and not suitable for their age. Therefore, educational strategies regarding safe behaviours have a key role in FB injuries prevention.
