BACKGROUND While epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitors (TKIs) exert a breakthrough effect, the incidence of skin disorders as a side effect has significantly reduced patients' quality of life. This study aimed to develop a treatment for inflammatory ulcers as one of the side effects of afatinib (Giotrif®), a second-generation EGFR-TKI, and established a skin disorder mouse model to investigate the protective effect of minocycline. METHODS First, under inhalation anesthesia with isoflurane, the back of a male ddy mouse was shaved, and afatinib petrolatum was applied alone or in combination with minocycline to observe the state of the skin and measure transepidermal water transpiration (TEWL). Next, afatinib was administered orally to mice, and minocycline petrolatum was applied to observe whether the skin disorder was prevented and its effect on repair of the skin disorder. RESULTS Skin injury occurred on the back of the mouse following afatinib (1 mg/g in petrolatum) application, and scab formation was observed. Application of minocycline prevented and improved the skin disorder caused by afatinib. When the minocycline-petrolatum mixture was applied to the mouse that developed the skin disorder, a significant improvement in TEWL was observed, and skin repair was observed macroscopically. CONCLUSIONS These results suggest that minocycline petrolatum applied locally prevents and repairs afatinib-induced skin disorders of non-small cell lung cancer patients. Histological examination of skin has provided insights into the mechanism of the occurrence of afatinib-related skin disorder and suggested the efficacy of minocycline topical application in clinical practice.BACKGROUND Testicular cancer (TC) is the most common malignancy in young adult men, and in many countries the incidence rates of testicular cancer have been increasing since the middle of the twentieth century. Since disease presentation and tumor progression patterns are often heterogeneous across racial groups, there may be important racial differences in recent TC trends. METHODS In this study, Surveillance, Epidemiology, and End Results (SEER) data on TC patients diagnosed between 1973 and 2015 were analyzed, including the following racial/ethnic groups non-Hispanic whites (NHW), Hispanic whites (HW), blacks, and Asians and Pacific Islanders (API). Patient characteristics, age-adjusted incidence rates, and survival were compared across racial groups. A multivariate Cox model was used to analyze the survival data of TC patients, in order to evaluate racial differences across several relevant factors, including marital status, age group, histologic type, treatment, stage, and tumor location. RESULTS NHWs had the highest incidence rates, followed by blacks, HWs, and APIs. There were significant survival differences among the racial groups, with NHWs having the highest survival rates and blacks having the lowest. CONCLUSION An analysis of SEER data showed that racial differences existed among TC patients in the United States with respect to patient characteristics, incidence, and survival. The results can be useful to stakeholders interested in reducing the burden of TC morbidity and mortality.BACKGROUND Esophageal squamous cell carcinoma (ESCC) is an aggressive cancer with one of the highest world incidences in the Eastern Cape region of South Africa. Several genome wide studies have been performed on ESCC cohorts from Asian countries, North America, Malawi and other parts of the world but none have been conducted on ESCC tumors from South Africa to date, where the molecular pathology and etiology of this disease remains unclear. We report here tumor associated copy number changes observed in 51 ESCC patients' samples from the Eastern Cape province of South Africa. METHODS We extracted tumor DNA from 51 archived ESCC specimens and interrogated tumor associated DNA copy number changes using Affymetrix® 500 K SNP array technology. The Genomic Identification of Significant Targets in Cancer (GISTIC 2.0) algorithm was applied to identify significant focal regions of gains and losses. Gains of the top recurrent cancer genes were validated by fluorescence in situ hybridization and their protein expressi%) was moderately expressed in samples with CCND1 DNA gain. Trichostatin A CONCLUSIONS This study reports copy number changes in a South African ESCC cohort and highlights similarities and differences with cohorts from Asia and Malawi. Our results strongly suggest a role for CTTN and SHANK2 in the pathogenesis of ESCC in South Africa.BACKGROUND Purtscher's retinopathy characterized by the appearance of cotton-wool spots and intraretinal hemorrhage at the posterior pole that commonly occurs after severe head and chest trauma. We report a patient who presented with multiple white retinal patches and retinal hemorrhage forty-two days after a severe thoracoabdominal trauma, which was misdiagnosed as Purtscher's retinopathy. CASE PRESENTATION A middle-aged woman presented to the eye clinic complaining of decreased vision and distortion in the right eye forty-two days after thoracoabdominal trauma. Upon first glance at her fundal appearances with multiple white retinal patches and retinal hemorrhage, we considered it to be bilateral Purtscher's retinopathy. No specific treatment was given to her. Ten days later, the four white retinal patches in the right eye joined together with star-shaped hard exudates and radial folds in the macula. This was not consistent with the characteristics of Purtscher's retinopathy. In retrospect, we found that thee. We concluded that in the case of multiple white retinal patches at the posterior pole in patients after trauma, especially in patients with infectious disease, Purtscher's retinopathy is not the only possible diagnosis. Correct diagnosis depends on reevaluation of the lesions by FFA and OCT, laboratory investigation and detailed history.BACKGROUND A recent systematic review identified very few studies on women's views on how to improve the quality of maternal and newborn care (QMNC). This study aimed at exploring the suggestions provided by women, after hospital delivery in Italy, on how to improve the QMNC. METHODS A questionnaire, containing open questions to capture suggestions on how to improve QMNC, was used to collect suggestions of mothers who gave birth a tertiary care referral hospital in Northeast Italy, between December 2016 and September 2018. Two authors independently used thematic analysis to analyse women's comments, using the WHO Standards for improving the QMNC as framework for the analysis. RESULTS Overall 392 mothers provided a total of 966 comments on how to improve the QMNC. Overall 45 (11.5%) women made suggestions pertinent to "provision of care", 222 (56.6%) to the "experience of care", 217 (55.4%) to "physical or to human resources". The top five suggestions were 1) increase presence of a companion during the whole hospitalization (28.
