Fate of sputum samples transported in bottles containing cetylpyridinium chloride and sodium chloride: a national reference laboratory study

The transportation of sputum samples may sometimes take more than one week which results in an increased contamination rate and loss of positive cultures. The current study was planned to analyze the recovery rate of mycobacteria from transported samples with and without Cetylpyridinium chloride (CPC). Addition of CPC is useful for isolation of M. tuberculosis from sputum subjected to long-term storage.     

Multiple idiopathic cervical resorption: a diagnostic dilemma

Multiple idiopathic cervical resorption is an uncommon condition, the etiology of which remains unknown. The case of a 36-year-old woman with idiopathic resorption in the cervical areas of multiple teeth is presented. Her medical history was noncontributory, but her dental history was valuable in reaching a diagnosis. Hematologic and endocrinal investigations were unremarkable, but a computed tomography scan revealed relevant information. The progression of the lesion and involvement of multiple teeth without any pattern or chronology are challenges faced when diagnosing and treating this condition.     

Is the consumption of fruit cariogenic?

Aim: The aim of this study was to investigate possible risk factors for dental caries in primary school children. Methods: Children aged 10–12 years (n = 257) residing in Lithgow, a non‐fluoridated community in New South Wales, Australia, were examined for caries experience in the permanent dentition. Information on dental practices, diet, residential movements, and socioeconomic status were obtained from self‐completed questionnaires. Results: Caries risk in the permanent teeth was associated with social disadvantage and diet. Among the dietary factors, the frequency of fruit consumption was associated with higher odds of caries experience (odds ratio: 1.52, 95% confidence intervals: 1.05, 2.21). Conclusions: Exposure to a high level of fruit consumption was suggestive of increased caries risk. Longitudinal studies are required to investigate the relationship between fruit consumption and dental caries.
