Magnetic Resonance Imaging (MRI) and neurological manifestations in SARS-CoV-2 patients.

OBJECTIVE: The "Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2)" disease caused a challenging and threating pandemic (COVID-19) worldwide with a great loss to life and the global economy. SARS-CoV-2 mainly involves the respiratory system, however, with Magnetic Resonance Imaging (MRI), neurological and special senses clinical manifestations have been reported rarely. The present study aims to investigate the MRI findings, clinical manifestations of neurological and special senses involvement in SARS-CoV-2 patients. MATERIALS AND METHODS: In this study, 284 articles from the databases "Pub-Med, Web of Science-Clarivate Analytics, Embase and Google Scholar" were identified. The keywords, coronavirus, SARS-CoV-2, COVID-19 pandemic, MRI, brain, special senses, neurological involvement were entered into the search engines and the concerned documents were selected and reviewed. The descriptive information was recorded from the particular studies; finally, we included 48 publications. RESULTS: The common neurological manifestations in SARS-CoV-2 patients were headache, impaired consciousness, acute cerebrovascular disease, ataxia, tremors, meningitis, encephalitis, cerebral bleeding, subarachnoid hemorrhage, frontal lobe, temporal lobe and intracerebral hematoma, hemiparesis and seizures. However, common special senses manifestations in SARS-CoV-2 patients were olfactory, auditory and gustatory disorders including red eyes, painless monocular visual disturbance, anosmia, ageusia, dysgeusia, dysosmia and hypoacusis. Moreover, the MRI findings identified in SARS-CoV-2 patients were isolated oval-shaped lesion in the corpus callosum, bilateral basal ganglia hemorrhage, ischemic lesions involving the corpus callosum, basal ganglia, cerebellum and vasogenic edema extending to the cerebral peduncles, pons and ventricles. CONCLUSIONS: The neurologic manifestations of SARS-CoV-2 patients are highly variable. The SARS-COV-2 exerts its damaging effects on the nervous system and special senses by developing determinant numerous neurological and special senses' clinical manifestations. Physicians with the help of MRI must rule out the neurological and special senses manifestations among SARS-CoV-2 patients.

Wildfire and COVID-19 pandemic: effect of environmental pollution PM-2.5 and carbon monoxide on the dynamics of daily cases and deaths due to SARS-COV-2 infection in San-Francisco USA.

OBJECTIVE: The wildfire allied environmental pollution is highly toxic and can cause significant wide-ranging damage to the regional environment, weather conditions, and it can facilitate the transmission of microorganisms and diseases. The present study aims to investigate the effect of wildfire allied pollutants, particulate matter (PM-2.5 µm), and carbon monoxide (CO) on the dynamics of daily cases and deaths due to Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection in San Francisco, USA. MATERIALS AND METHODS: For this study, we selected San Francisco, one of the regions affected by the wildfires allied pollution in California, USA. The data on the COVID-19 pandemic in San Francisco, including daily new cases and new deaths were recorded from Worldometer Web. The daily environmental pollutants particulate matter (PM-2.5 µm) and carbon monoxide (CO) were recorded from the metrological web "BAAQMD". The daily cases, deaths, particulate matter (PM-2.5 µm) and carbon monoxide were documented from the date of the occurrence of the first case of (SARS-CoV-2) in San Francisco, CA, USA, from March 20, 2020 to Sept 16, 2020. RESULTS: The results revealed a significant positive correlation between the environmental pollutants particulate matter (PM2.5 µm) and the number of daily cases (r=0.203, p=0.007), cumulative cases (r=0.567, p<0.001) and cumulative deaths (r=0.562, p<0.001); whereas the PM2.5 µm and daily deaths had no relationship (r=-0.015, p=0.842). In addition, CO was also positively correlated with cumulative cases (r=0.423, p<0.001) and cumulative deaths (r=0.315, p<0.001), however, CO had no correlation with the number of daily cases (r=0.134, p=0.075) and daily deaths (r=0.030, p=0.693). In San Francisco, one micrometer (µg/m3) increase in PM2.5 caused an increase in the daily cases, cumulative cases and cumulative deaths of SARS-COV-2 by 0.5%, 0.9% and 0.6%, respectively. Moreover, with a 1 part per million (ppm) increase in carbon monoxide level, the daily number of cases, cumulative cases and cumulative deaths increased by 5%, 9.3% and 5.3%, respectively. On the other hand, CO and daily deaths had no significant relationship. CONCLUSIONS: The wildfire allied pollutants, particulate matter PM-2.5µm and CO have a positive association with an increased number of SARS-COV-2 daily cases, cumulative cases and cumulative deaths in San Francisco. The metrological, disaster management and health officials must implement the necessary policies and assist in planning to minimize the wildfire incidences, environmental pollution and COVID-19 pandemic both at regional and international levels.

Impact of weather conditions on incidence and mortality of COVID-19 pandemic in Africa.

OBJECTIVE: The weather-related conditions change the ecosystem and pose a threat to social, economic and environmental development. It creates unprecedented or unanticipated human health problems in various places or times of the year. Africa is the world's second largest and most populous continent and has relatively changeable weather conditions. The present study aims to investigate the impact of weather conditions, heat and humidity on the incidence and mortality of COVID-19 pandemic in various regions of Africa. MATERIALS AND METHODS: In this study, 16 highly populated countries from North, South, East, West, and Central African regions were selected. The data on COVID-19 pandemic including daily new cases and new deaths were recorded from World Health Organization. The daily temperature and humidity figures were obtained from the weather web "Time and Date". The daily cases, deaths, temperature and humidity were recorded from the date of appearance of first case of "Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2)" in the African region, from Feb 14 to August 2, 2020. RESULTS: In African countries, the daily basis mean temperature from Feb 14, 2020 to August 2, 2020 was 26.16±0.12°C, and humidity was 57.41±0.38%. The overall results revealed a significant inverse correlation between humidity and the number of cases (r= -0.192, p<0.001) and deaths (r= -0.213, p<0.001). Similarly, a significant inverse correlation was found between temperature and the number of cases (r= -0.25, p<0.001) and deaths (r=-0.18, p<0.001). Furthermore, the regression results showed that with 1% increase in humidity the number of cases and deaths was significantly reduced by 3.6% and 3.7% respectively. Congruently, with 1°C increase in temperature, the number of cases and deaths was also significantly reduced by 15.1% and 10.5%, respectively. CONCLUSIONS: Increase in relative humidity and temperature was associated with a decrease in the number of daily cases and deaths due to COVID-19 pandemic in various African countries. The study findings on weather events and COVID-19 pandemic have an impact at African regional levels to project the incidence and mortality trends with regional weather events which will enhance public health readiness and assist in planning to fight against this pandemic.

Effect of heat and humidity on the incidence and mortality due to COVID-19 pandemic in European countries.

OBJECTIVE: The weather allied conditions have an impact on air, water, soil, food, ecosystem, feelings, behaviors, and pattern of health and disease. The present study aims to investigate the impact of heat and humidity on the daily basis incidence and mortality due to COVID-19 pandemic in European countries. MATERIALS AND METHODS: We selected 10 European countries, Russia, United Kingdom, Spain, Italy, Germany, Turkey, France, Belgium, Netherlands and Belarus. This region has a relatively low temperature and high humidity, and has homogenous European ethnicity with almost similar socioeconomic culture and health care system. The data on COVID-19 pandemic including daily new cases and new deaths were recorded from World Health Organization (WHO). The information on daily temperature and humidity was obtained from world climate web "Time and Date". The daily cases, deaths, temperature and humidity were recorded from the date of appearance of first case of "Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2)" in the European region, from Jan 27, 2020 to July 17, 2020. RESULTS: In 10 European countries, (Russia, United Kingdom, Spain, Italy, Germany, Turkey, France, Belgium, Netherlands and Belarus), the daily basis mean temperature from Jan 27, 2020 to July 17, 2020 was 17.07±0.18°C, and humidity was 54.78±0.47%. The overall results revealed a significant inverse correlation between humidity and the number of cases (r= -0.134, p<0.001) and deaths (r= -0.126, p<0.001). Moreover, an increase in temperature was linked with an increase in the number of cases (r=0.062, p=0.013) and deaths (r=0.118, p<0.001). The regression analysis results further revealed that with an increase of 1% humidity the number of cases (ß = -15.90, p<0.001) and deaths (ß=-1.56, p<0.001) reduced significantly. Whereas, with an increase of 1°C in temperature the number of cases (ß = 20.65, p<0.001) and deaths (ß = 3.71, p<0.001) increased significantly. CONCLUSIONS: Increase in relative humidity was associated with a decrease in the number of daily cases and deaths, however, a rise in temperature was allied with an upsurge in the number of daily cases and daily deaths due to COVID-19 pandemic in European countries. The study findings on weather events and COVID-19 pandemic have an impact at European regional levels to project the incidence and mortality trends with regional weather events to enhance public health readiness and assist in planning to fight against this pandemic situation.

Climate and COVID-19 pandemic: effect of heat and humidity on the incidence and mortality in world's top ten hottest and top ten coldest countries.

OBJECTIVE: The COVID-19 pandemic has caused a global public health crisis with social, psychological and long-lasting economical damages. Weather-related dynamics have an impact on the pattern of human health and disease. The present study aimed to investigate the impact of heat and humidity on daily basis incidence and mortality due to COVID-19 pandemic in ten of the world's hottest countries compared to ten of the coldest ones. MATERIALS AND METHODS: Worldwide, we selected 20 countries; 10 hottest countries with the highest temperatures and 10 coldest countries with the lowest temperature. The selection of the countries was based on the daily basis mean temperature from the date of appearance of the initial cases of COVID-19, Dec 29, 2019 to May 12, 2020. In the world's 10 hottest countries, the mean temperature was (26.31±1.51) and humidity (44.67±4.97). However, in the world's 10 coldest countries the mean temperature was (6.19±1.61) and humidity (57.26±2.35). The data on the global outbreak of COVID-19, daily new cases and deaths were recorded from World Health Organization, and daily information on temperature and humidity was obtained from metrological web "Time and Date". RESULTS: In countries with high temperatures and low humidity, the mean daily cases incidence were (407.12±24.33); cumulative cases (9094.34±708.29); and cumulative deaths (452.84±43.30) were significantly low compared to countries with low temperatures and high humidity: daily cases (1876.72±207.37); cumulative cases (44232.38±5875.11); and cumulative deaths (2008.29±310.13). Moreover, COVID-19 cases and deaths per million population were significantly low in countries with high temperatures (cases 711.23, and deaths 16.27) compared to countries with low temperatures (cases 1685.99; and deaths 86.40). Furthermore, in hottest countries, a 1% increase in humidity reduced number of cases and deaths by (ß = -5.40, p<0.001) and (ß = -0.187, p=0.004) respectively. A similar trend was seen with a 1°C increase in temperature, reducing the number of deaths by (ß = -1.35. p<0.001). CONCLUSIONS: The results revealed a significant decrease in incidence of daily cases and deaths in countries with high temperatures and low humidity (warmest countries), compared to those countries with low temperatures and high humidity (coldest countries). The findings could be of interest to the policymakers and the health officials on the epidemiological trends of COVID-19 pandemic and weather changes.

Effect of temperature and humidity on the dynamics of daily new cases and deaths due to COVID-19 outbreak in Gulf countries in Middle East Region.

OBJECTIVE: Weather-related dynamics have an impact on the pattern of health and disease. The present study aimed to investigate the effect of temperature and humidity on the daily new cases and daily new deaths due to COVID-19 in Gulf Cooperation Council (GCC) countries in the Middle East. MATERIALS AND METHODS: We selected all the six GCC countries, including Saudi Arabia, United Arab Emirates, Bahrain, Kuwait, Qatar and Oman. This region has a relatively high temperature and humidity, and has homogenous Arab ethnicity with a similar socioeconomic culture. The data on the global outbreak of COVID-19, including daily new cases and deaths were recorded from World Health Organization. The information on daily temperature and humidity was obtained from world climate web "Time and Date". The daily basis, mean temperature and humidity were recorded from the date of appearance of first case of COVID-19 in the region, Jan 29, 2020 to May 15, 2020. We also evaluated the growth factor, "a ratio by which a quantity multiplies itself over time; it equals daily cases divided by cases on the previous day". RESULTS: In GCC countries, the daily basis mean temperature from Jan 29, 2020 to May 15, 2020 was 29.20±0.30°C and humidity was 37.95±4.40%. The results revealed that there was a negative correlation and decrease in the number of daily cases and deaths from COVID-19 with increase in humidity in Oman, Kuwait, Qatar, Bahrain, United Arab Emirates and Saudi Arabia. The correlation coefficient between temperature with daily cases shows that an increase in temperature was associated with an increase in daily cases and deaths due to COVID-19, however, the temperature is still gradually rising in the region. The growth factor result for daily cases was 1.09±0.00 and daily deaths was 1.07±0.03 for COVID-19, and shows declining trends in GCC region. CONCLUSIONS: An increase in relative humidity was associated with a decrease in the number of daily cases and deaths due to COVID-19 in GCC countries. The daily growth factor for patients and deaths shows a declining trend. However, the climate is swiftly changing in the region; further studies may be conducted during the peak of summer season. The findings have outcomes for policymakers and health officials about the impact of temperature and humidity on epidemiological trends of daily new cases and deaths due to COVID-19.

Long-term sustained lesion clearance from Lmax with imiquimod 3.75%, a new field-directed treatment for actinic keratosis.

BACKGROUND: In patients with actinic keratosis (AK), subclinical and clinical lesions coexist across large areas of sun-exposed skin. The long-term efficacy of AK treatments depends on their ability to eradicate both types of lesions across the entire field. OBJECTIVE: To assess the long-term efficacy of imiquimod 3.75% using the reduction in lesions from Lmax (maximum lesion count during treatment), which assesses the ability to clear subclinical and clinical lesions. METHODS: Patients with 5-20 AK lesions on the full face or balding scalp from two 14-week, randomized, vehicle-controlled, double-blind studies of imiquimod 3.75% (daily for two 2-week treatment cycles separated by a 2-week treatment-free period) were eligible to enter a 12-month follow-up study if they had no AK lesions at Week 14. Lesion reduction from Lmax was calculated at 6 and 12 months during follow-up. RESULTS: The 42 patients in this long-term study had a median of nine baseline lesions and a median Lmax of 22 lesions. At 6 and 12 months of follow-up, the median absolute reduction in AK lesions from Lmax with imiquimod 3.75% was 21 and 19, respectively. The median percentage reduction in lesions from Lmax to 6 and 12 months was 100% and 97.2%, respectively. CONCLUSIONS: The ability of imiquimod 3.75% to eliminate clinical and subclinical lesions across an entire sun-exposed field translates into sustained long-term efficacy. Imiquimod 3.75% may therefore represent a first-choice treatment for patients with AK.

Efficacy of imiquimod 3.75% from Lmax according to the number of actinic keratosis lesions.

BACKGROUND: Imiquimod 3.75% reduces 92.2% of all actinic keratosis (AK) lesions, assumed to include both subclinical and clinical lesions, across a large sun-exposed field such as the full face or balding scalp. OBJECTIVE: To evaluate the efficacy of imiquimod 3.75% using the reduction in lesions from Lmax (the maximum lesion count during treatment) in subgroups of patients with low and high AK lesion counts. METHODS: Patients from two 14-week, placebo-controlled, double-blind studies were subgrouped according to whether they had ≤ 10 or >10 AK lesions at baseline. Treatment was applied to the full face or balding scalp during two 2-week treatment cycles separated by a 2-week treatment-free interval. RESULTS: Overall, 167 patients had ≤ 10 lesions and 152 patients had >10 AK lesions at baseline. With imiquimod 3.75%, the median percentage reduction in AK lesions from Lmax to end of study was similar in patients with ≤ 10 and >10 baseline lesions (91.5% and 93.0% respectively). The median absolute reduction in AK lesions from Lmax to end of study was 24.0 for patients with >10 baseline lesions and 10.0 for those with ≤ 10 baseline lesions. The median percentage and absolute reductions in lesions from Lmax were significantly greater with imiquimod 3.75% vs. placebo (P < 0.0001). CONCLUSIONS: Imiquimod 3.75% is effective regardless of disease severity as shown in this study by the reduction of over 90% of lesions from Lmax in patients with low or high AK lesion counts.

Dermatitis atópica desde la perspectiva del paciente: desencadenantes, cumplimiento de las recomendaciones médicas y control de la enfermedad. Estudio DATOP / Patient Perspectives on Triggers, Adherence to Medical Recommendations, and Disease Control in Atopic Dermatitis: The DATOP Study

INTRODUCCIÓN Y OBJETIVOS: Conocer, desde la perspectiva del paciente, los desencadenantes de la dermatitis atópica (DA), el grado de control percibido y el cumplimiento de las indicaciones médicas y su calidad de vida relacionada con la salud (CVRS). PACIENTES Y MÉTODOS: Estudio epidemiológico, transversal, multicéntrico incluyendo pacientes adultos (> 16 años; n = 125) y pediátricos (entre 2-15 años; n = 116) con DA de intensidad moderada-grave, más de 12 meses de evolución y con episodios de lesiones activas moderados-graves (escala de evaluación global del investigador [IGA] > 2). Se analizaron los desencadenantes informados por los pacientes, el cumplimiento de las recomendaciones y el tratamiento farmacológico (TF), las diferencias en CVRS y el control percibido (U de Mann-Whitney) según la gravedad de la DA (índice SCORAD-SCORing Atopic Dermatitis). RESULTADOS: Los desencadenantes más frecuentes fueron: cosméticos, ropa, ácaros, detergentes/jabones y cambios de temperatura. El 47,2% de los pacientes adultos y el 39,7% de los pediátricos no aplicaban el TF desde el inicio del episodio. El TF, la hidratación y los consejos médicos de cuidado fueron las recomendaciones más seguidas. El 41,6 y el 27,6% (adultos y pediátricos, respectivamente) consideraba que su grado de control era insuficiente y se asoció con la gravedad de la DA en adultos (p = 0,014). CONCLUSIONES: El grado de control actual de la DA es mejorable, especialmente en adultos. Aunque los pacientes indican seguir las recomendaciones médicas, un porcentaje significativo no aplica correctamente los tratamientos. Parece necesario potenciar la educación sobre la enfermedad y su manejo para mejorar el grado de control y potenciar su CVRS

INTRODUCTION AND OBJECTIVES: To analyze the triggers of atopic dermatitis (AD), adherence to medical recommendations, disease control, and health-related quality of life (HRQOL) from the patient's perspective. PATIENTS AND METHODS: This was a multicenter, cross-sectional, epidemiological study with the participation of adults (age > 16 years; n = 125) and children (age, 2-15 years, n = 116). Patients had a history of at least 12 months of moderate to severe AD with a moderate to severe flare (Investigator Global Assessment score > 2) at the time of recruitment. The Mann-Whitney U test was used to evaluate relationships between disease severity, determined according to the Scoring in Atopic Dermatitis index, and triggers reported by patients, adherence to recommendations and pharmacological therapy, HRQOL, and patient-perceived control. RESULTS: The most common triggers were cosmetic products, clothing, mites, detergents/soaps, and changes in temperature. In 47.2% of adults and 39.7% of children, pharmacological therapy was not initiated at flare onset. Adherence was highest to pharmacological therapy, skin moisturizing, and medical care recommendations. Disease control was considered insufficient by 41.6% of adults and 27.6% of pediatric patients and, in adults, this was associated with the severity of AD (P = 0.014). CONCLUSIONS: The therapeutic control of AD is susceptible to improvement, especially in adults. Although patients state that they follow medical recommendations, a significant percentage of patients do not apply recommended treatments correctly. Better education about the disease and its management would appear to be necessary to improve disease control and HRQOL

Reacción granulomatosa a cuerpo extraño a sílice, silicona y ácido hialurónico, en paciente con sarcoidosis inducida por interferón / Foreign Body Granulomatous Reaction to Silica, Silicone, and Hyaluronic Acid in a Patient With Interferon-Induced Sarcoidosis

Se describe el caso de una paciente que desarrolló granulomas sarcoideos 11 meses después de haber iniciado interferón α pegilado y ribavirina, como tratamiento de la hepatitis crónica C. Las lesiones se localizaban en relación a 3 cuerpos extraños diferentes: sílice en cicatrices cutáneas antiguas, ácido hialurónico que se había inyectado previamente en la cara, y silicona que se detectó en una adenopatía axilar donde había drenado de un implante mamario previo. La paciente también aquejaba tos seca, fiebre y en la analítica se detectó un incremento de la enzima convertidora de angiotensina y de las enzimas hepáticas. A partir de estos hallazgos se diagnosticó de sarcoidosis sistémica y se suspendió el tratamiento antiviral con posterior normalización de las pruebas hepáticas, desaparición de las lesiones cutáneas y de las adenopatías. Los dermatólogos y cosmetólogos deben ser conscientes del riesgo de aparición de manifestaciones sarcoideas en las áreas donde se han realizado implantes estéticos, en los sujetos que en un futuro requieran tratamiento con interferón (AU)

We report the case of a patient who developed sarcoid granulomas 11 months after starting treatment with pegylated interferon alfa and ribavirin for chronic hepatitis C. The sites of the lesions were related to 3 different foreign bodies: silica in old scars on the skin, hyaluronic acid that had been injected into facial tissues, and silicone in an axillary lymph node draining the area of a breast implant. Systemic sarcoidosis was diagnosed on the basis of a history of dry cough and fever and blood tests that revealed elevated angiotensin converting enzyme and liver enzymes. Interruption of the antiviral therapy led to normalization of liver function tests and disappearance of the skin lesions and lymphadenopathies. Dermatologists and cosmetic surgeons should be aware of the risk of sarcoid lesions related to cosmetic implants in patients who may require treatment with interferon in the future (AU)

Calidad de vida relacionada con la salud, satisfacción y cumplimiento de los pacientes con dermatitis atópica moderada-grave que siguen un tratamiento farmacológico de mantenimiento. Estudio CONDA-SAT / Health-Related Quality of Life, Patient Satisfaction, and Adherence to Treatment in Patients With Moderate or Severe Atopic Dermatitis on Maintenance Therapy: The CONDA-SAT Study

Introducción y objetivos: Evaluar la calidad de vida relacionada con la salud (CVRS), la satisfacción y cumplimiento en pacientes con dermatitis atópica (DA) moderada-grave en tratamiento farmacológico de mantenimiento. Material y métodos: Estudio epidemiológico, multicéntrico, nacional, transversal con pacientes adultos y pediátricos diagnosticados de DA moderada o grave de al menos 16 meses de evolución y en tratamiento de mantenimiento. Se aplicó el Índice de Calidad de Vida en Dermatología (DLQI), el Cuestionario Dermatológico de Calidad de Vida Infantil (CDLQI), la versión para menores de 4 años (IDQOL), la Escala de Afectación de la Dermatitis Atópica (EADA), el test de Morisky-Green y escalas visuales analógicas de satisfacción. Se comparó la CVRS entre pacientes con afectación moderada y grave (U de Mann-Whitney) y la duración y número de brotes antes y después de la terapia de mantenimiento (prueba de Wilcoxon). Resultados: Participaron 141 pacientes pediátricos y 141 adultos con DA moderada en el 85,8 y 79,4% de los casos, respectivamente. El impacto en CVRS fue leve-moderado. La duración y número de los brotes disminuyeron desde la aplicación del tratamiento de mantenimiento (p < 0,001). Aunque la satisfacción fue alta en ambos grupos, el cumplimiento fue muy bajo (entre el 18,4-42,6% en pediátricos y entre el 14,9-27,0% en adultos). Conclusiones: Los pacientes con DA moderada o grave que siguen tratamiento farmacológico de mantenimiento presentan una reducción en la duración y número de los brotes y menor afectación de su CVRS. Además, los pacientes están satisfechos con el tratamiento aunque su cumplimiento es mejorable (AU)

Objective: To evaluate health-related quality of life (HRQOL), patient satisfaction, and adherence to treatment in patients with moderate or severe atopic dermatitis on maintenance therapy. Material and methods: We performed a national, multicenter, cross-sectional, epidemiological study in adults and children with moderate or severe atopic dermatitis of at least 16 months’ duration who were receiving maintenance therapy. We used the Dermatology Life Quality Index (DLQI), the children's version of this scale (cDLQI), and the Morisky medication adherence scale. Visual analog scales were used to measure treatment satisfaction. We used the Mann-Whitney U test to compare HRQOL between patients with moderate and severe disease and the Wilcoxon test to compare the frequency and duration of flares before and after the start of maintenance therapy. Results: We studied 141 children and 141 adults; the prevalence of moderate AD in these groups was 85.8% and 79.4%, respectively. The impact of AD on HRQOL was mild to moderate. Maintenance therapy led to a significant decrease in the frequency and duration of flares (P <0 .001). While treatment satisfaction was high in both groups, adherence was poor (18.4%-42.6% in children and 14.9%-27.0% in adults). Conclusions: Patients with moderate and severe AD receiving maintenance therapy experience a reduction in the number and duration of flares and an improvement in HRQOL. While treatment satisfaction is high, adherence rates could be improved (AU)

Guidelines for the management of vitiligo: the European Dermatology Forum consensus.

The aetiopathogenic mechanisms of vitiligo are still poorly understood, and this has held back progress in diagnosis and treatment. Up until now, treatment guidelines have existed at national levels, but no common European viewpoint has emerged. This guideline for the treatment of segmental and nonsegmental vitiligo has been developed by the members of the Vitiligo European Task Force and other colleagues. It summarizes evidence-based and expert-based recommendations (S1 level).

Foreign body granulomatous reaction to silica, silicone, and hyaluronic acid in a patient with interferon-induced sarcoidosis.

We report the case of a patient who developed sarcoid granulomas 11 months after starting treatment with pegylated interferon alfa and ribavirin for chronic hepatitis C.
