Multidisciplinary management of patients with pubic osteomyelitis, a rare but serious complication after surgery and radiation therapy for advanced gynaecological cancer.

Pubic osteomyelitis is a rare and often late-onset complication of radiation therapy and surgery for vulvar and vaginal carcinoma. It typically presents with vulvar pain, fever, vaginal discharge and/or gait disorders. Pubic osteomyelitis is often accompanied by fistulas or wound dehiscence in the pelvic area. Its accurate diagnosis and treatment are challenging and require a multidisciplinary team effort. In our patients, multiple combined surgical procedures, long-term antibiotic treatment and days to weeks of hospital admission were necessary to treat pubic osteomyelitis. We emphasise the importance of timely and adequate diagnosis and multidisciplinary approach resulting in a course of treatment that is as effective as possible, limiting the impact on quality of life, which is generally high in this group of patients.

Consortium analysis of gene and gene-folate interactions in purine and pyrimidine metabolism pathways with ovarian carcinoma risk.

SCOPE: We reevaluated previously reported associations between variants in pathways of one-carbon (1-C) (folate) transfer genes and ovarian carcinoma (OC) risk, and in related pathways of purine and pyrimidine metabolism, and assessed interactions with folate intake. METHODS AND RESULTS: Odds ratios (OR) for 446 genetic variants were estimated among 13,410 OC cases and 22,635 controls, and among 2281 cases and 3444 controls with folate information. Following multiple testing correction, the most significant main effect associations were for dihydropyrimidine dehydrogenase (DPYD) variants rs11587873 (OR = 0.92; p = 6 × 10⁻5) and rs828054 (OR = 1.06; p = 1 × 10⁻4). Thirteen variants in the pyrimidine metabolism genes, DPYD, DPYS, PPAT, and TYMS, also interacted significantly with folate in a multivariant analysis (corrected p = 9.9 × 10⁻6) but collectively explained only 0.2% of OC risk. Although no other associations were significant after multiple testing correction, variants in SHMT1 in 1-C transfer, previously reported with OC, suggested lower risk at higher folate (p(interaction) = 0.03-0.006). CONCLUSION: Variation in pyrimidine metabolism genes, particularly DPYD, which was previously reported to be associated with OC, may influence risk; however, stratification by folate intake is unlikely to modify disease risk appreciably in these women. SHMT1 SNP-by-folate interactions are plausible but require further validation. Polymorphisms in selected genes in purine metabolism were not associated with OC.
