From ‘Legionellosis acquired through a dental unit’ to ‘Was Legionellosis acquired through a dental unit?’
No full textThe case reported by Scho ̈nning et al.1 refers to a case described online by Lundholm of a 67-year-old male with a diagnosis of leukaemia. On 20 November 2012, the patient was admitted to hospital to undergo high-dose chemotherapy before undergoing bone marrow transplantation. On 22 November, he underwent routine dental examination. Chemotherapy was performed on 28 November. On 3 December, the patient started to show respiratory symptoms. He was admitted to the intensive care unit where he died from
Legionnaires’ disease (LD). The analysis of the environmental samples performed in the dental ward is intriguing. Water from the cup filler was positive [2000 colony-forming units (cfu)/L] for the same Legionella pneumophila serogroup 1 specimen detected in the patient’s sputum collected through bronchoscopy. All the remaining 38 water samples resulted negative. According to Lundholm, these samples included the dental unit, which was subjected to water treatment regularly. Despite this treatment, a high level of heterotrophic bacteria (200 cfu/mL) was detected in dental unit water
Elder neglect-oral diseases and injuries
No full textElder neglect (EN) is the failure of a designated caregiver to meet the needs of a dependent older person. World EN prevalence, meta-analyzed in this study, is 1.0% or 1.8% according to different statistical methods. Referring alleged EN cases to Adult Protective Services (APSs) by healthcare workers (HCWs) is mandatory in many countries. However, only few claims are substantiated, as EN could be confused with Self-Neglect, and neglect could be unintentional or due to caregiver unawareness. Screening tools are inaccurate, and their use is discouraged by public health organizations, because they lead to too many false positives, which engulf the already overwhelmed APSs. HCWs need effective tools with objective judgments, which do not hamper the HCW-caregiver-patient rapport and prevent lawsuits when allegations are unfounded. Orofacial EN manifestations (poor oral/denture hygiene, lack of needed/improper dentures, dry mouth, skin/mucosal rashes) are essential Forensic Markers of EN. I classified EN-associated oral diseases according to the unmet needs into four groups: (1) traumatic injuries due to lack of caregiver vigilance (e.g., maxillofacial fractures); (2) diseases due to oral hygiene deficiency (e.g., root caries); (3) diseases typical of the elderly with late/no diagnosis (e.g., oral cancer); and (4) diseases typical of the elderly exacerbated by psychological distress (e.g., oral lichen planus)
Did a patient acquire legionella pneumophila from the cup filler of a dental unit or did a patient infected with l. pneumophila contaminate the cup filler?
No full textSchonning and colleagues reported the case of a man with diagnosis of leukaemia admitted to hospital to undergo bone marrow transplantation who underwent a dental check-up and high-dose chemotherapy and developed Legionnaires’ disease in the following days. The authors entitled their case report ‘Legionellosis acquired through a dental unit’ [1]. I showed that it was not possible to confirm whether the patient acquired Legionella pneumophila from a contaminated dental unit or whether the patient, already infected with L. pneumophila, contaminated the dental unit water system
NA0D – The new traumatic dental injury classification of the world health organization
No full textAn accurate, clear, and easy-to-
use
traumatic dental injury (TDI) classification and definition
system is a prerequisite for proper diagnosis, study, and treatment. However,
more than 50 classifications have been used in the past. The ideal solution would be
that TDIs are adequately classified within the International Classification of Diseases
(ICD), endorsed by the World Health Organization (WHO). TDI classification provided
by the 11th Revision of the ICD (ICD-11),
released in 2018, and previous Revisions,
failed to classify TDIs satisfactorily. Therefore, in December 2018, a proposal was submitted
by Dr's Stefano Petti, Jens Ove Andreasen, Ulf Glendor, and Lars Andersson, to
the ICD-11,
asking for a change of the existing TDI classification. Proposal #2130 highlighted
the TDI paradox, the fifth most frequent disease/condition neglected by most
public health agencies in the world, and the limits of ICD-11
classification. Namely,
injuries of teeth and periodontal tissues were located in two separate blocks that did
not mention dental/periodontal tissues; infraction, concussion, and subluxation were
not coded; most TDIs lacked description; and tooth fractures were described through
bone fracture descriptions (e.g., comminuted, compression, and fissured fractures).
These limitations led to TDI mis-reporting,
under-reporting,
and non-specific
reporting
by untrained non-dental
healthcare providers. In addition, no scientific articles on
TDIs, present in PubMed, Scopus, and Web-of-
Science,
used the ICD classification.
Proposal #2130 suggested to adopt the Andreasen classification, the most widely
acknowledged classification used in dental traumatology. The Proposal was reviewed
by two WHO teams, two scientific Committees, one WHO Collaborating Center, and
the Department of Non-Communicable
Disease Prevention at WHO headquarters,
and it underwent two voting sessions. In March 2022, the Andreasen classification
was accepted integrally. A new entity was generated, called NA0D, “Injury of teeth
or supporting structures” (https://icd.who.int/brows e11/l-m/
en#/http://id.
who.int/icd /ent ity/141 3338122). Hopefully, this will contribute to increasing
the public awareness, and the dental profession's management, of TDIs
