Nipple candidiasis and painful lactation: an updated overview.

Nipple pain and discomfort during or after breastfeeding remains one of the most common reasons for premature cessation of lactation among the affected women. The belief that yeasts, and especially Candida spp., are responsible for such symptoms is highly supported by many physicians, midwives, or lactation specialists, but is also viewed with scepticism by other health care providers. The aim of this paper is to provide an updated report of the evidence against, as well as in favour of, the "Candida hypothesis". Several studies have documented that lactating women with symptoms such as nipple soreness, with or without radiating breast pain, are more likely to test positive for Candida spp. than non-symptomatic women. However, its role as an undisputable aetiopathogenic factor for infection in these cases cannot always be established. Physicians should evaluate thoroughly such patients, because early and correct recognition of the underlying problem can prevent phenomena of early weaning.

Real-world clinical outcomes of treatment with brodalumab in patients with moderate-to-severe psoriasis: a retrospective, 24-month experience from four academic dermatology centers in Greece.

OBJECTIVE: To assess the real-world clinical treatment outcomes with brodalumab in patients with moderate-to-severe plaque psoriasis in Greece. MATERIALS AND METHODS: This was a longitudinal, retrospective, real-world analysis of data from medical records of 106 patients with moderate-to-severe plaque psoriasis, treated with brodalumab for up to 24 months at four University Dermatology Centers in Greece. Efficacy assessments of psoriasis severity [Psoriasis Area and Severity Index (PASI) and Body Surface Area affected (BSA) scores] and its impact on patients' quality of life (QoL) [Dermatology Life Quality Index (DLQI) score] were evaluated at different timepoints up to 24 months. RESULTS: Treatment with brodalumab reduced both mean PASI (14.0-1.5, p < .001) and BSA scores (21.6-2.5, p < .001) across all visits. This effect was accompanied by reduction in mean DLQI score (12.8-2.1, p < .001) across all visits compared with baseline. Moreover, therapeutic efficacy was affected by prior biologic treatment exposure, as biologic naïve patients had greater reductions in all scores from baseline following treatment with brodalumab (numerical for mean PASI, significant for mean BSA and DLQI scores). CONCLUSION: Brodalumab is effective long term, improving disease severity and health-related QoL in patients with moderate-to-severe plaque psoriasis in a real-world setting.

Clinical associations and classification of immune checkpoint inhibitor-induced cutaneous toxicities: a multicentre study from the European Academy of Dermatology and Venereology Task Force of Dermatology for Cancer Patients.

BACKGROUND: Cutaneous immune-related adverse events (irAEs) represent the most frequent toxicities induced by immune checkpoint inhibitors (ICIs). OBJECTIVES: To investigate clinical associations of cutaneous toxicities induced by different ICI therapies. METHODS: This was a multicentre retrospective international cohort study of patients with cancer who developed cutaneous irAEs under ICI therapy. Analysis was performed of the rates and basic characteristics of all cutaneous toxicities, and identification of any associations was performed using univariate and multivariate models. RESULTS: In total, 762 patients were included, who developed 993 cutaneous toxicities. Forty different types of skin toxicities were identified. Psoriasis (175 patients, 23·0%) and pruritus (171 patients, 22·4%) were the most common toxicities, followed by macular rash (161 patients, 21·1%) and eczematous-type reactions (150 patients, 19·7%). Multivariate analysis showed that among patients with macular rash, vitiligo or multiple toxicities, patients received ICIs more frequently for melanoma than for NSCLC. Moreover, anti-CTLA4 was less frequent than anti-programmed death 1 treatment in patients with macular rash [odds ratio (OR) 0·11, 95% confidence interval (CI) 0·01-0·76] and vitiligo (OR 0·07, 95% CI 0·006-0·78). A significant association was also seen in patients treated with a combination of ICI and chemotherapy vs. ICI monotherapy. They less frequently developed psoriasis (OR 0·08, 95% CI 0·02-0·31), lichenoid reactions (OR 0·15, 95% CI 0·03-0·77) and eczematous reactions (OR 0·24, 95% CI 0·07-0·78), all compared with pruritic rash. CONCLUSIONS: Our study showed that skin-oriented toxicities do not share a single pattern and are related to several factors, including the specific agent administered and the underlying malignancy treated. Follow-up plans should be individualized in order to minimize the risk for severe reactions that could compromise optimum therapeutic outcome. What is already known about this topic? Patients with cancer treated with different immune checkpoint inhibitors (ICIs) carry an increased risk of developing various types of skin toxicities. What are the clinical implications of this work? In this multicentre cohort study we showed that ICI-related skin toxicities do not share a single pattern and may depend on several factors, including the specific agent administered and the underlying malignancy. Among patients with macular rash, vitiligo or multiple skin toxicities, patients received ICIs more frequently for melanoma than for non-small cell lung cancer. The combination of ICI and chemotherapy compared with ICI monotherapy occurred to a lesser extent in patients with psoriatic rash lichenoid and eczematous reactions, compared with patients with pruritus. Clinical awareness and specialized dermatological consultation should be advocated.

Deregulation of methylation of transcribed-ultra conserved regions in colorectal cancer and their value for detection of adenomas and adenocarcinomas.

Expression of Transcribed Ultraconserved Regions (T-UCRs) is often deregulated in cancer. The present study assesses the expression and methylation of three T-UCRs (Uc160, Uc283 and Uc346) in colorectal cancer (CRC) and explores the potential of T-UCR methylation in circulating DNA for the detection of adenomas and adenocarcinomas. Expression levels of Uc160, Uc283 and Uc346 were lower in neoplastic tissues from 64 CRC patients (statistically significant for Uc160, p<0.001), compared to non-malignant tissues, while methylation levels displayed the inverse pattern (p<0.001, p=0.001 and p=0.004 respectively). In colon cancer cell lines, overexpression of Uc160 and Uc346 led to increased proliferation and migration rates. Methylation levels of Uc160 in plasma of 50 CRC, 59 adenoma patients, 40 healthy subjects and 12 patients with colon inflammation or diverticulosis predicted the presence of CRC with 35% sensitivity and 89% specificity (p=0.016), while methylation levels of the combination of all three T-UCRs resulted in 45% sensitivity and 74.3% specificity (p=0.013). In conclusion, studied T-UCRs' expression and methylation status are deregulated in CRC while Uc160 and Uc346 appear to have a complicated role in CRC progression. Moreover their methylation status appears a promising non-invasive screening test for CRC, provided that the sensitivity of the assay is improved.
