RESUMEN
Porphyromonas gingivalis is the primary microbe in the "periodontal red complex" bacteria (PRCB) along with Tannerella forsythia and Treponema denticola, which are linked to periodontal disease (PD). These pathogens are also implicated in various systemic disorders, but their association with the incidence of gastrointestinal (GI) cancer is less explored. A systematic review followed by a meta-analysis was conducted as per standard guidelines (Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) 2022) to find this association between GI cancers and PRCB after a literature search for full-text papers in the English language (between 2010 and 2023) in databases (Cochrane Library, PubMed, and Web of Science) with suitable keywords using the Boolean search strategy. Data extraction involved titles, abstracts, and full texts retrieved and scored by the modified Newcastle-Ottawa Scale. The data were analyzed by the Review Manager (RevMan 5.2, Cochrane Collaboration, Denmark). Standard Cochran Q test and I2 statistics (for heterogeneity) and a random effects model (pooled OR with 95% CI) were applied to report results. P. gingivalis among the PRCB was linked to GI cancers (OR: 2.16; 95% CI: 1.34-3.47). T. forsythia and T. denticola did not show meaningful associations as per existing evidence for GI cancers.
RESUMEN
A 24-year-old male patient presented with the principal complaint of deposits on his teeth and gingival pigmentation. After examination, he was diagnosed with chronic generalized gingivitis. He was further referred for pre-procedural routine blood investigations. Bleeding time, clotting time, and his random blood sugar values were normal. CBC report revealed the presence of erythrocytosis with microcytic hypochromic red blood cells. Following this peripheral smear was taken which reveals the presence of polychromatophils, target cells and a few spherocytes. Haemoglobin electrophoresis by high-performance liquid chromatography (HPLC) was performed which disclosed 90.8% of HbE, suggestive of homozygous haemoglobinopathy. He had no other associated systemic findings, and there was no relevant family history. The patient was informed about his condition and stated to have pre-marital and pre-natal genetic counselling in the future. The patient being a carrier of the thalassaemic trait happened to know his condition incidentally, which could prevent future complications.
RESUMEN
Lichen planus is a chronic inflammatory mucocutaneous disorder that is seen in skin and oral mucosa. Definitive etiology for oral lichen planus remains unknown. It may or may not be associated with skin lesions. Different clinical patterns such as reticular, plaque, erosive, bullous, and atrophic are seen in oral mucosa of which bullous lichen planus is a rare entity. We present a unique case of bullous lichen planus in a 20-year-old male without skin manifestations along with the review of literature comprising various case reports of bullous lichen planus.
