Oral malodor (halitosis) is a common concern in Western society. As with other human perceptions, emotional as well as cognitive variables play a major role in one's sensation and complaint. To study factors potentially associated with the complaint of oral malodor, periodontal and psychological evaluations were carried out on 38 subjects (66% female, mean age 43 years) with a complaint of oral malodor. Subjects underwent evaluation of their periodontal status, odor evaluation by an odor judge, and psychopathological symptom survey by means of the SCL-90 questionnaire. The patient's self-rating of oral odor was significantly higher than the evaluation of an objective odor judge and was not associated with their periodontal status. The SCL-90 profile of subjects was relatively higher than that of an age- and gender-matched reference group of dental patients. The results suggest that the complaint of oral malodor may be related to psychopathological symptoms as recorded by the SCL-90 questionnaire.

: Halitosis is primarily caused by the activity of oral microorganisms. In this study, we employed metagenomic sequencing and metabolomic approaches to investigate the differences in salivary microbiota and metabolite profiles between individuals with halitosis and periodontitis and healthy controls. Additionally, we expanded the study to examine how oral malodorous compounds interact with human oral squamous carcinoma (HSC-4) cells.

Shoulder abscesses, commonly resulting from bacterial infections, can occasionally present with atypical etiologies and delayed onset. We report a rare case of a massive polymicrobial shoulder abscess developing two decades after an insect bite, emphasizing its clinical presentation, diagnostic approach, and surgical management. A 65-year-old female presented with severe, progressively worsening right shoulder pain, a 20 cm swelling, and purulent discharge persisting for 15 days.

Article Synopsis
- Percutaneous endoscopic gastrostomy (PEG) placement is a routine procedure for patients needing non-oral feeding, but it can lead to rare complications like gastrocolocutaneous fistula, where the bowel is caught during placement.
- A 73-year-old male on hospice experienced malodorous leakage from his PEG tube months after placement, prompting an emergency department visit where imaging revealed the tube was incorrectly positioned in the transverse colon.
- The patient was treated non-surgically by removing the PEG tube and switching to a nasogastric tube for nutrition, highlighting the need for careful tube management and awareness of potential complications such as gastrocolocutaneous fistula in similar cases.
