Abstract
The prevalence of mathematical difficulties (MD) among primary school children in China and its related factors remain unclear. To provide a suitable foundation for formulating appropriate screening and intervention strategies, this study aimed to estimate the prevalence of MD and its possible factors among primary school children in China. Articles were identified from seven databases and included if they reported on the prevalence of MD among primary school children in China. A total of 30,881 articles were retrieved, 975 of which were subjected to full evaluation. In total, 54 studies involving 34,815 participants (mean age 9.86 ± 3.13 years) were included. Analyses were conducted using the Meta and Metafor packages in the statistical software environment R. We used meta-regression and subgroup analyses by variable type to evaluate the potential prevalence factors. The pooled prevalence of MD among primary school children in China was 8.97%, whereas the prevalence rates of MD in lower, middle, and upper primary schools were 11.57%, 10.07%, and 4.76%, respectively. The results showed that the prevalence of MD among primary school children in China was significantly related to grade level and the cut-off points selected for screening MD and that the prevalence of MD in middle primary school was higher in girls than in boys. The prevalence of MD in primary schools in China was slightly higher than that in countries such as the United Kingdom and the United States. The prevalence of MD was higher in the lower and middle grades of primary school. The grade level and cut-off points selected during MD screening were closely related to the prevalence of MD. More attention should be paid to girls with MD in middle primary school.

Abstract
OBJECTIVES In kidney transplant, the use of immunosuppressive drugs, indispensable to avoid organ rejection, implies an increased risk of several infectious and neoplastic diseases. Cutaneous infections have a high incidence in kidney transplant recipients and are diagnosed in 55% to 97% of these patients. The objectives of this study were to identify the most frequent skin diseases and their clinical risk factors within a population of kidney transplant recipients. MATERIALS AND METHODS We reviewed the medical records of 200 kidney transplant recipients at Sahloul Teaching Hospital, Tunisia, between November 2007 and January 2018. We analyzed the clinical data of patients who sought skin consultations with either dermatologists or plastic surgeons within the hospital. We collected patient sociodemographic data, type of donor, and type of immunosuppressive therapy used by recipients. We also obtained history of skin lesions and examination findings. RESULTS Among 200 patients included in our study cohort, 131 were male and 69 were female. Age ranged from 6 to 75 years with a mean age of 30.51 ± 12 years. Patients had received kidneys from either living or deceased donors, with available data indicating 96.5% living donors and 3.5% deceased donors. The mean time interval from transplant to first skin consultation was 31 month (range, 3 months to 10 years). Prevalence of various skin conditions was 48.5%. We found that 62.9% of cases were skin infections, 59.8% were drug-induced skin conditions, and 2.9% were skin cancers. The estimated risk factors for skin lesions include use of cyclosporin and duration of immunosuppression. CONCLUSIONS Our study demonstrated the spectrum of skin conditions that can be expected after kidney transplant. Careful dermatological screening and long-term follow-up are needed for these patients to reduce posttransplant skin complications.

Abstract
BACKGROUND Research examining skin disease in heart and lung transplant recipients in Australia is limited. This study aims to determine the spectrum of skin diseases encountered in Australian heart and lung transplant recipients, their effect on quality of life, and potential risk factors for skin cancer. METHODS Ninety-four participants were recruited from an Australian heart and lung transplant centre between March and December 2016. The participants were asked to fill out a questionnaire which included the Dermatology Life Quality Index and were examined for malignant and non-malignant skin disease. The association of study variables with the presence of skin cancer and Dermatology Life Quality Index score were examined using logistic regression analysis. RESULTS A dermatological diagnosis was made in 82 patients (87%). Actinic keratosis was the most common diagnosis, affecting 50 participants (53%), followed by skin cancer (41; 44%) and warts (14; 15%). Other non-malignant skin diseases were less common. Risk factors associated with skin cancer on multivariate modelling included age at transplantation and a history of ≥5 post-transplant skin cancers. Skin disease had a negative effect on the quality of life of a minority of patients. CONCLUSION Actinic keratosis and skin cancer are very frequent in Australian heart and lung transplant recipients and more common than non-malignant skin diseases. Routine dermatological surveillance at regular intervals is advised.

Abstract
INTRODUCTION Lifelong immunosuppression after renal transplant exerts effects on the recipients' skin, including skin infections, skin cancers and drug-induced skin disorders. Our study aimed to determine the epidemiology of skin conditions among renal transplant recipients in the largest tertiary hospital in Singapore. METHODS We reviewed the medical records of kidney transplant recipients at Singapore General Hospital, Singapore, between 1 January 2003 and 31 December 2013. Among these patients, the clinical data of patients who sought skin consultations with either dermatologists or plastic surgeons within the hospital was captured. RESULTS A total of 178 patients were included in our study. There were 88 (45.6%) skin infections, 23 (11.9%) drug-induced skin conditions, 9 (4.7%) skin cancers and 73 (37.8%) other skin conditions. Skin infection was the predominant reason for consultation, with viral warts (15%, n = 29) being the most common. Of the nine cases in our cohort with skin cancer, there were three cases of basal cell carcinoma, three cases of Bowen's disease, two cases of extramammary Paget's disease and one case of squamous cell carcinoma. Drug-induced skin conditions, mainly attributable to long-term steroids and cyclosporin use, were represented by acne (9.3%, n = 18) and sebaceous hyperplasia (2.6%, n = 5). CONCLUSION Our study demonstrated the spectrum of skin conditions that can be expected after renal transplantation. We wish to highlight the importance of careful dermatological screening and long-term follow-up for these patients, in order to reduce post-transplant skin complications.

Abstract
Importance The risk for skin cancer has been well characterized in white organ transplant recipients (OTRs); however, most patients on the waiting list for organ transplant in the United States are nonwhite. Little is known about cutaneous disease and skin cancer risk in this OTR population. Objective To compare the incidence of cutaneous disease between white and nonwhite OTRs. Design, Setting, and Participants This retrospective review of medical records included 412 OTRs treated from November 1, 2011, through April 22, 2016, at an academic referral center. Prevalence and characteristics of cutaneous disease were compared in 154 white and 258 nonwhite (ie, Asian, Hispanic, and black) OTRs. Clinical factors of cutaneous disease and other common diagnoses assessed in OTRs included demographic characteristics, frequency and type of cancer, anatomical location, time course, sun exposure, risk awareness, and preventive behavior. Main Outcomes and Measures Primary diagnosis of malignant or premalignant, infectious, and inflammatory disease. Results The 412 patients undergoing analysis included 264 men (64.1%) and 148 women (35.9%), with a mean age of 60.1 years (range, 32.1-94.3 years). White OTRs more commonly had malignant disease at their first visit (82 [67.8%]), whereas nonwhite OTRs presented more commonly with infectious (63 [37.5%]) and inflammatory (82 [48.8%]) conditions. Skin cancer was diagnosed in 64 (41.6%) white OTRs and 15 (5.8%) nonwhite OTRs. Most lesions in white (294 of 370 [79.5%]) and Asian (5 of 6 [83.3%]) OTRs occurred in sun-exposed areas. Among black OTRs, 6 of 9 lesions (66.7%) occurred in sun-protected areas, specifically the genitals. Fewer nonwhite than white OTRs reported having regular dermatologic examinations (5 [11.4%] vs 8 [36.4%]) and knowing the signs of skin cancer (11 [25.0%] vs 10 [45.4%]). Conclusions and Relevance Early treatment of nonwhite OTRs should focus on inflammatory and infectious diseases. Sun protection should continue to be emphasized in white, Asian, and Hispanic OTRs. Black OTRs should be counseled to recognize the signs of genital human papillomavirus infection. Optimal posttransplant dermatologic care may be determined based on the race or ethnicity of the patients, but a baseline full-skin assessment should be performed in all patients. All nonwhite OTRs should be counseled more effectively on the signs of skin cancer, with focused discussion points contingent on skin type and race or ethnicity.

Abstract
Uruguay, with a total population of 3,345,000 inhabitants, is the Latin American country with the second highest number of renal replacement therapies. Long-term immunosuppressant therapy is essential for graft survival but results in reduced immunosurveillance, leading to an increased risk of complications. A variety of dermatological manifestations and a large increase in nonmelanoma skin cancers have been reported in this population. The purpose of this study was to evaluate the frequency and clinical spectrum of cutaneous manifestations in renal and renopancreatic recipients in 2 reference centers in Uruguay. Two hundred and six renal or renopancreatic recipients between 21 and 77 years old were evaluated between September 2009 and September 2011. A total of 206 dermatoses were observed; 60% of the patients had at least 1 cutaneous manifestation. The most frequent dermatoses were cutaneous side effects due to immunosuppressive treatment (40.6%), followed by infections (26.1%), miscellaneous causes (18.9%), and malignant and premalignant lesions (14.4%). Transplant recipients represent a high-risk dermatological population. Physicians in transplant units should be aware of the importance of dermatological screening in order to promote early detection of skin cancer.

Abstract
Uruguay is the second country of Latin America in prevalence of renal replacement therapies, including functioning kidney allografts. Long-term immunosuppressive therapy is essential for adequate graft function, but results in reduced immunosurveillance leading to an increased risk of complications such as infections and malignancies. A variety of cutaneous manifestations as well as an increase in non-melanoma skin cancers have been reported in this population. The objective of this study was to evaluate the frequency and clinical spectrum of cutaneous manifestations in renal and reno-pancreatic recipients in Uruguay. One hundred renal or reno-pancreatic recipients aged between 21- and 77-years-old were evaluated between September 2009 and September 2010. A total of 104 dermatoses were observed; 68% of the patients had at least one cutaneous manifestation. The most frequent dermatoses were cutaneous side effects due to immunosuppressive treatment (43.3%), followed by infections (27.9%), miscellaneous causes (22.1%), as well as malignant and premalignant lesions (6.7%). This is the first study evaluating dermatological complications in organ transplant recipients in our country. Most of the patients had at least one dermatological manifestation of immunosuppression, including a malignant or pre-malignant lesion, highlighting that this is a high-risk dermatological population. Cancer is one of the most important causes of death in recipients with functioning grafts. Its prevention is a major goal in the care of transplant recipients. Physicians in transplant units should be aware of the importance of dermatological screening and skin cancer surveillance.

Abstract
Nonneoplastic mucocutaneous lesions are frequent in organ transplant recipients. Many of them are caused by a direct toxicity of immunosuppressive drugs, in particular glucocorticoids and cyclosporine. The effects of these agents are dose- and time-dependent. Glucocorticoids can cause acne, Cushingoid appearance, irregular purpuric areas, friable skin, and wide and violaceous stripes. Cyclosporine can cause hypertrichosis, pilosebaceous lesions, and gum hypertrophy. Patients with esthetic changes may show poor adherence to treatment with these immunosuppressive agents that may lead to progressive graft dysfunction. Apart from this direct toxicity, vigorous immunosuppression may render the transplant recipients more susceptible to mucocutaneous infections. Fungal infection, viral warts, and bacterial folliculitis are the most frequent types of mucocutaneous infection. Some fungal infections, such as oral candidiasis and pityriasis versicolor, are relatively trivial, but other mycotic infections can cause severe or disfigurating lesions. Among viral infections, warts and condylomata caused by human papilloma virus are frequent and may favor the development of nonmelanoma skin cancer. Bacterial infections are usually trivial in the early period after transplantation, being represented almost exclusively by folliculitis. However, subcutaneous infections may cause a necrotizing fasciculitis which is a life-threatening disorder, usually sustained by polymicrobial pathogens.

Abstract
Introduction: There is no published epidemiological data on skin diseases in kidney transplant recipients in this tropical country, which has multi-ethnic groups with the Chinese as the predominant ethnic group. Materials and Methods: Skin diseases of 143 renal transplant recipients were studied in a skin clinic of a tertiary institution during annual surveillance visits from June 2006 to March 2009. Results: Our study showed that except the common drug specific skin manifestations, sebaceous hyperplasia (56.6%), seborrheic keratosis (60.8%), melanocytic naevi (76.9%), skin tags (37.1%) and viral (29.4%) and fungal (20.3%) infections were the most prevalent skin diseases among renal transplant recipients living in Singapore. The prevalence of pre-malignant and malignant tumours was very low (11.2% actinic keratosis, 1.4% Bowen’s disease, 1.4% squamous cell carcinoma, 0.7% basal cell carcinoma, 0.7% keratoacanthoma). Male predominance was seen in sebaceous hyperplasia (72.4% vs 32.1%), actinic keratosis (17.2% vs 1.8%), viral (36.8% vs 19.6%) and fungal (27.6% vs 8.9%) infections. Our study also showed increased prevalence of sebaceous hyperplasia with increased age but its prevalence was significantly higher than that reported in the age matched general population. The prevalence of seborrheic keratosis, actinic keratosis and viral infection correlated positively with post-transplant duration. Conclusions: Our study provides epidemiological data for the prevalence of skin diseases in renal transplant recipients. It emphasises the importance of dermatologic follow-up for renal transplant patients in order to obtain a diagnosis and manage treatable skin diseases.

Abstract
BACKGROUND The risk of skin infections in renal transplant recipients (RTRs) has been described previously; however, it differs markedly by ethnic groups, skin type, and geographical location. We investigated the prevalence and nature of skin infections in a large series of RTRs in our locality in Egypt. PATIENTS AND METHODS A total 302 RTRs (216 males and 86 females) were included in this study. They were screened for the presence of bacterial, fungal, and viral skin infections depending on clinical signs, Woods lamp examinations, culture, and biopsy if indicated. The patients were compared with 300 healthy controls matched for age and sex (200 males and 100 females). RESULTS We found 191 (63.25%) RTRs had some kind of skin infection. Folliculitis (10.3%), tinea versicolor (30.1%), dermatophytosis (19.5%), and onychomycosis (7.6%) were statistically significantly more common in RTRs compared with control subjects. CONCLUSION Our RTRs have higher prevalence rates of folliculitis and superficial fungal infections than the healthy population and they should be searched for in every patient with renal transplantation to ensure early treatment and avoid complications. Low-dose ketoconazole should be considered in renal transplant populations with high rates of superficial fungal infections, as it may reduce risk of such infections.
