Effects of oral isotretinoin treatment for acne vulgaris patients on anger responses and the relationship with temperament

SUMMARY OBJECTIVE: Isotretinoin is the only medication against all the factors involved in acne vulgaris pathogenesis. The aim of our study was to verify whether patients with acne vulgaris receiving isotretinoin therapy exhibit elevated anger levels and to observe the correlation between age, temperament traits, and anger. METHODS: The study group comprised a sum of 100 cases, involving 50 individuals with acne vulgaris-required high-dose retinol therapy and 50 controls who did not start any medication. RESULTS: Our study showed that anger levels increased with drug use. A positive correlation between cyclothymic temperament, the anxiety-related behavior subdimension, and the introvert and passive-aggressive subdimension of interpersonal anger reactions has been recognized. In addition, a positive one was observed between hyperthymic temperament and the introvert subdimension, which is one of the anger-related thoughts and interpersonal anger reactions. CONCLUSION: This study elucidates anger dimensions such as anger-related thoughts, behaviors, and reactions in individuals who received retinol treatment for acne vulgaris. In addition to anger and its dimensions, temperament was also investigated. Although several studies have investigated the relationship between acne vulgaris and psychiatric symptoms, to the best of our knowledge, no research has been reported in the English-language literature regarding the relationship between anger dimensions and temperament after retinol treatment that might make our study an original and valuable contribution to the literature.

Adult acne versus adolescent acne: a narrative review with a focus on epidemiology to treatment

Abstract Acne vulgaris is one of the most common chronic inflammatory diseases and is characterized by papules, pustules, comedones, and nodules. Although adolescence is the preferential age group, acne may affect various age groups. Acne shares different properties in adults and adolescents. These differences extend from epidemiology to treatments. Increased awareness of these two subtypes will allow for better management of the disease. In this review, the authors examined all aspects of acne in adults and adolescents under the light of current literature.

Impact of COVID-19 pandemic on the course of refractory chronic spontaneous urticaria under omalizumab treatment

Abstract Background: The course of chronic spontaneous urticaria (CSU) can be influenced by infections, depression, and stress. Objectives: Our aim was to investigate the impact of the COVID-19 pandemic on the course of refractory CSU together with patient adherence to omalizumab and treatment adjustments. Methods: Urticaria Activity Score (UAS7) was used to assess disease activity. Fear of COVID-19 Scale (FC-19s), and Depression Anxiety Stress Scale (DASS-21s) were performed to assess mental health status. All scales were performed during the Quarantine Period (QP) and Return to the Normal Period (RTNP). UAS7 Before Pandemic (BP) was recorded from the patients medical records. Results: The authors evaluated 104 omalizumab-receiving CSU patients. UAS7 scores during QP were significantly higher than those in RTNP and BP (p < 0.01). DASS-21 and FC-19 scores were significantly higher during QP compared to RTNP (p < 0.01). Nineteen (18.2%) patients ceased omalizumab, 9 patients prolonged the intervals between subsequent doses during the pandemic. UAS7 scores in QP were significantly higher in patients who ceased omalizumab than in those who continued (p < 0.001). Among patients who continued omalizumab, 22.4% had an increase in urticaria activity and higher FC-19 scores in comparison with those with stable disease activity (p = 0.008). Study limitations: The small sample size of patients with prolonged intervals of omalizumab and the lack of mental health evaluation with the same tools prior to the study. Conclusions: Fear induced by COVID-19 can determine an increase in disease activity. Therefore, patients on omalizumab should continue their treatment and prolonged interval without omalizumab can be considered in patients with good urticaria control.

¿Existe asociación del tiempo entre el urocultivo y la cirugía intrarrenal retrógrada y la tasa de síndrome de respuesta inflamatoria sistémica? / Does time elapsed between urine culture and retrograde intrarenal surgery affect the rate of systemic inflammatory response syndrome?

Objetivo: Identificar los factores preoperatorios e intraoperatorios que podrían causar el síndrome de respuesta inflamatoria sistémica (SRIS) tras la cirugía intrarrenal retrógrada (CRIR) y estudiar el efecto del tiempo de espera entre la fecha del urocultivo vesical preoperatorio (UCVP) y la fecha de la cirugía en el SRIS postoperatorio.Materiales y métodos: La población objetivo la constituyeron 467 pacientes intervenidos mediante CRIR entre enero de 2013 y junio de 2020. Se obtuvieron UCVP de todos los pacientes antes de la cirugía. En el postoperatorio, los pacientes recibieron seguimiento estrecho en busca de fiebre y otros signos de SRIS. Se realizaron análisis de regresión logística univariante y multivariante para revelar los factores predictivos de SRIS después de CRIR.Resultados: La cohorte completa del estudio estaba formada por 467 pacientes. La tasa de SRIS fue del 5,6%. En el análisis univariante, la tasa de diabetes mellitus, los antecedentes de infección urinaria recurrente, el tiempo quirúrgico y la carga litiásica fueron factores predictivos significativos de SRIS. Según el análisis multivariante, la tasa de antecedentes de infección urinaria recurrente, el tiempo quirúrgico y la carga litiásica eran factores predictivos estadísticamente significativos. El tiempo transcurrido entre la fecha de realización del UCVP y la fecha de la cirugía fue el mismo en el grupo con SRIS y en el grupo normal.Conclusión: El intervalo de tiempo entre la fecha de realización del UCVP y la fecha de la cirugía no es un factor influyente para el SRIS. Aclarar esta cuestión mediante estudios prospectivos puede ayudar a resolver este problema con el que los endourólogos se enfrentan con frecuencia en la práctica diaria. (AU)

Objective: To identify the preoperative and intraoperative factors that might cause systemic inflammatory response syndrome (SIRS) after retrograde intrarenal surgery (RIRS), and to investigate the effect of time elapsed between the date of performing preoperative bladder urine culture (PBUC) and surgery date on postoperative SIRS.Materials and methods: Four hundred sixty-seven patients who had RIRS between January 2013 and June 2020 constituted the target population of this study. PBUC were obtained from all patients before undergoing surgery. Postoperatively, patients were closely monitored for fever and other signs of SIRS. Univariate and multivariate logistic regression analysis were performed to reveal the predictive factors for SIRS after RIRS.Results: The entire study cohort consisted of 467 patients. The rate of SIRS was 5.6%. In univariate analysis, the rate of diabetes mellitus, recurrent urinary tract infection history, surgical time, and stone burden were significant predictive factors for SIRS. In multivariate analysis, the rate of recurrent urinary tract infection history, surgical time and stone burden were observed to be statistically significant predictive factors. Time elapsed between the date of performing PBUC and surgery date was not different between the SIRS group and the normal group.Conclusion: We conclude that the time between the date of performing PBUC and surgery date is not an influential factor for SIRS. Clarifying this issue with prospective studies may be useful, as endourologists frequently encounter this situation in daily practice. (AU)

Evaluation of the efficacy, safety, and side effects of secukinumab in patients with moderate-to-severe psoriasis: real-world data from a retrospective multicenter study

Abstract Background: Clinical studies have demonstrated that IL-17A inhibition with secukinumab is effective for clearing the skin of patients with psoriasis and has a favorable safety profile. Objective: The authors aim to determine whether secukinumab is effective and safe for the treatment of moderate-to-severe chronic psoriasis based on clinical experience with this drug. Method: The authors conducted a multicenter retrospective study in nine referral centers and included patients with psoriasis who had received secukinumab between March 2018 to November 2020. Data on demographic characteristics, Psoriasis Area and Severity Index (PASI) scores, and previous treatments were collected from medical records. Patients were evaluated at 12, 24, and 52 weeks with respect to response to treatment and side effects. Results: In total, 229 patients were recruited for the study. A PASI score improvement of ≥90 points over the baseline was achieved by 79%, 69.8%, and 49.3% of patients at weeks 12, 24, and 52, respectively. The most common adverse events wereCandida infections and fatigue. In total, 74 (32%) patients discontinued treatment by week 52, including due to adverse events, or secondary ineffectiveness. Study limitations: Retrospective design. Conclusions: These findings suggest that secukinumab therapy is reasonably effective in patients with moderate-to-severe psoriasis. Comorbidities and time length of the disease can affect the response to treatment. The rates of adverse events were high in this patient population.

Sacroiliitis in children and adolescents with familial Mediterranean fever

Abstract Background: Familial Mediterranean fever (FMF) is an autoinflammatory disease characterized by recurrent episodes of fever and serositis. Sacroiliitis can be observed in some FMF patients. This study aimed to compare the demographic, clinical, and laboratory findings, and treatment in children with FMF and sacroiliitis, and children with juvenile spondyloarthropathy (JSpA). Methods: In total, 1687 pediatric FMF patients that were followed-up between May 2010 and June 2020 were evaluated retrospectively. Among them, those with sacroiliitis ( n = 63) were included in the study and compared to patients with JSpA ( n = 102). Results: The study included 63 FMF patients with sacroiliitis (38 males [60.3%] and 25 females [39.7%]) with a mean age of 15.2 ± 4.1 years. Mean age at symptom onset was 7.2 ± 5.05 years and mean age at diagnosis was 9.74 ± 4.67 years. The most common mutation in the FMF patients was M694V/M694V ( n = 22). Patients were diagnosed with sacroiliitis with a mean of 12 months (range: 6-36 months) after the diagnosis of FMF. Among the FMF patients, 28 (44.4%) had enthesitis, 23 (36.5%) had heel pain, and 11 (17.4%) had low back pain. The study also included 102 JSpA patients (90 males [88.2%] and 12 females [11.8%]). Mean age of patients with JSpA was 16.1 ± 2.8 years. As compared to 102 JSpA patients, patients with FMF and sacroiliitis had higher acute phase reactants, whereas HLA- B27 positivity rate was lower. In addition, axial involvement rate was higher in the JSpA patients. Conclusion: Sacroiliitis is a common co-morbidity in FMF patients. The phenotypic features of these patients are different from patients with JSpA.

ABSTRACT Objective: To determine NANDA-I nursing diagnoses and NIC nursing interventions in patients who underwent radical prostatectomy. Method: A cross-sectional and descriptive study was conducted in a research and teaching hospital in western Turkey between June 2016 and June 2017. The sample included adult patients diagnosed with prostate cancer in the immediate postoperative period of radical prostatectomy. Data collection was performed using Gordon's Functional Health Patterns, NANDA-International and Nursing Interventions Classification Taxonomy Systems. Results: Participants were 54 adult patients. The main nursing diagnoses were in the classes of "physical injury", "self-care", "hydration" and "physical comfort". Some nursing diagnoses were identified in all patients, namely: "risk for deficient fluid volume", "risk for imbalanced fluid volume", "impaired urinary elimination". The most selected NIC interventions were in the classes of "risk management", "elimination management", "coping assistance", "tissue perfusion management" and "self-care facilitation". Conclusion: future studies with larger populations are needed to explore the nursing diagnoses and effects of nursing interventions on patients who underwent radical prostatectomy.

[Gangliosides in the serum in lung carcinoma]. / Serumski gangliozidi kod karcinoma pluca.

In this study, tumor and serum gangliosides were analyzed in patients bearing lung planocellular carcinoma (LPC) before and after operative therapy. Tumor tissue, pathohistologically characterized as carcinoma planocellulare corneum (Ca. epidermoide, type 8070/3, WHO, Geneva, 1981), showed an elevated concentration of gangliosides in comparison to normal tung tissue. The composition of gangliosides in LPC tissue varied from one tumor sample to another, however, two general features were observed. First, LPC contained an increased amount of GM3 and a decreased amount of GD3 gangliosides. Second, an elevated proportion of gangliosides migrating as polysialogangliosides (x3, x5, x6) characterized the majority of LPC tissues. On the other hand, serum of patients with LPC contained an elevated amount of gangliosides (15.8 +/- 0.3 mumols/L) in comparison to control serum (6.1 +/- 0.8 mumols/L) (P less than 0.01). However, analyzing the composition of serum gangliosides by thin-layer chromatography, all serum gangliosides were more or less elevated. By day 21 after the surgical removal of LPC, serum gangliosides dropped by approximately 50% approaching the normal values. It seems that elevated serum gangliosides in LPC patients were secreted from carcinoma cells, because they normalized after surgical removal of LPC. Thus, serum gangliosides might be a useful biochemical tool for diagnosis and therapy monitoring of this carcinoma.

Evaluation of choroidal perfusion changes in obese patients: ocular effects of insulin resistance / Avaliação das alterações da perfusão coroidiana em pacientes obesos: efeitos oculares da resistência à insulina

ABSTRACT Purpose: We aimed to evaluate choroidal per­fusion changes in obese patients using optical coherence tomography and dynamic contour tonometry, to determine whether these changes are associated with body mass index, and to assess the ocular effects of insulin resistance. Methods: We retrospectively evaluated the data of 32 obese patients with body mass index >30 kg/m2 and 45 healthy control individuals. Intraocular pressure and ocular pulse amplitude values of the patients were measured using dynamic contour tonometry, and the mean choroidal thickness was measured using enhanced depth imaging optical coherence tomography. Insulin resistance was assessed using the homeostasis model assessment-estimated insulin resistance index. Results: The mean choroidal thickness (294.30 ± 60.87 μm) and ocular pulse amplitude (2.10 ± 0.74) were lower, whereas the mean intraocular pressure (16.61 ± 2.35 mmHg) was higher in obese patients than in controls. There was a significant negative correlation between body mass index and ocular pulse amplitude (r=-0.274; p=0.029) and an insignificant negative correlation between mean choroidal thickness, intraocular pressure, and body mass index. There was an insignificant negative correlation between homeostasis model assessment-estimated insulin resistance index, mean choroidal thickness, and intraocular pressure and significant ne­gative correlation between homeostasis model assessment-estimated insulin resistance index and ocular pulse amplitude (r=-0.317; p=0.022). Conclusion: We found reduced mean choroidal thickness and ocular pulse amplitude and increased mean intraocular pressure in obese patients. These changes indicated a decrease in choroidal perfusion and ocular blood flow. It may be possible to detect ocular blood flow changes in obese patients through noninvasive assessment using the choroid. The negative correlation between insulin resistance and ocular pulse amplitude may be associated with intracellular fat accumulation in obese patients.

RESUMO Objetivo: Avaliar as alterações da perfusão coroidiana em pacientes obesos utilizando tomografia de coerência óptica e a tonometria de contorno dinâmico, para determinar se essas alterações estão associadas ao índice de massa corporal e avaliar os efeitos oculares da resistência à insulina. Métodos: Foram avaliados, retrospectivamente, os dados de 32 pacientes obesos, com índice de massa corporal >30 kg/m2, e 45 controles saudáveis. Os valores de pressão intraocular e da amplitude de pulso ocular dos pacientes foram medidos por meio de tonometria de contorno dinâmico e a espessura média da coroide foi medida por tomografia de coerência óptica com profundidade de imagem aprimorada. A resistência à insulina foi avaliada usando o índice de estimativa da resistência à insulina pelo modelo de homeostase. Resultados: A espessura média da coroideia (294,30 ± 60,87 μm) e a amplitude de pulso ocular (2,10 ± 0,74) foram menores, enquanto a pressão intraocular média (16,61 ± 2,35 mmHg) foi maior nos obesos do que nos controles. Houve uma correlação negativa significativa entre o índice de massa corporal e a amplitude de pulso ocular (r=-0,274; p=0,029) e uma correlação negativa insignificante entre a espessura média da coroide, a pressão intraocular e o índice de massa corporal. Houve uma correlação negativa insignificante entre a avaliação do modelo de homeostase - estimativa do índice de resistência à insulina, espessura média da coróide e pressão intraocular e correlação negativa significativa entre o modelo de avaliação de homeostase - o índice de resistência à insulina estimado e a amplitude de pulso ocular (r=-0,317; p=0,022). Conclusão: Encontramos redução da espessura média da coroide e da amplitude de pulso ocular e aumento da pressão intraocular em pacientes obesos. Essas alterações indicaram uma diminuição na perfusão coroidal e no fluxo sanguíneo ocular. Pode ser possível detectar alterações no fluxo sanguíneo ocular em pacientes obesos por meio de avaliação não invasiva usando a coróide. A correlação negativa entre a resistência à insulina e a amplitude de pulso ocular pode estar associada ao acúmulo de gordura intracelular em pacientes obesos.

Effectiveness of caudal septal extension graft application in endonasal septoplasty / Eficácia da aplicação de enxerto de extensão septal caudal em septoplastia endonasal

Abstract Introduction Septal deviation is a common disease seen in daily otorhinolaryngology practice and septoplasty is a commonly performed surgical procedure. Caudal septum deviation is also a challenging pathology for ear, nose, and throat specialists. Many techniques are defined for caudal septal deviation. Objective To evaluate the effectiveness of caudal septal extension graft (CSEG) application in patients who underwent endonasal septoplasty for a short and deviated nasal septum. Methods Forty patients with nasal septal deviation, short nasal septum, and weak nasal tip support who underwent endonasal septoplasty with or without CSEG placement between August 2012 and June 2013 were enrolled in this study. Twenty patients underwent endonasal septoplasty with CSEG placement. The rest of the group, who rejected auricular or costal cartilage harvest for CSEG placement, underwent only endonasal septoplasty without any additional intervention. Using the Nasal Obstruction Symptom Evaluation (NOSE) and Rhinoplasty Outcome Evaluation (ROE) questionnaires, pre- and post-operative acoustic rhinometer measurements were evaluated to assess the effect of CESG placement on nasal obstruction. Results In the control group, preoperative and postoperative minimal cross-sectional areas (MCA1) were 0.44 ± 0.10 cm2 and 0.60 ± 0.11 cm2, respectively (p < 0.001). In the study group, pre- and postoperative MCA1 values were 0.45 ± 0.16 cm2 and 0.67 ± 0.16 cm2, respectively (p < 0.01). In the control group, the nasal cavity volume (VOL1) value was 1.71 ± 0.21 mL preoperatively and 1.94 ± 0.17 mL postoperatively (p < 0.001). In the study group, pre- and postoperative VOL1s were 1.72 ± 0.15 mL and 1.97 ± 0.12 mL, respectively (p < 0.001). Statistical analysis of postoperative MCA1 and VOL1 values in the study and the control groups could not detect any significant intergroup difference (p = 0.093 and 0.432, respectively). In the study group, mean nasolabial angles were 78.15 ± 4.26º and 90.70 ± 2.38º, respectively (p < 0.001). Conclusion Endonasal septoplasty with CESG placement is an effective surgical procedure with minimal complication rate for subjects who have a deviated, short nasal septum and weak nasal tip support.

Resumo Introdução Desvio septal é doença comum no cotidiano da prática otorrinolaringológica e a septoplastia é procedimento cirúrgico comum. Desvio caudal do septo nasal é também uma condição desafiadora para os otorrinolaringologistas. São muitas as técnicas definidas para desvio caudal do septo nasal. Objetivo Avaliar a eficácia da aplicação de enxerto de extensão septal caudal (EESC) em pacientes que passaram por septoplastia endonasal devido a septo nasal curto e com desvio. Método Foram recrutados para o estudo 40 pacientes com desvio de septo nasal, septo nasal curto e fraca sustentação da ponta do nariz, tratados com septoplastia endonasal com ou sem a aplicação de EESC, entre agosto de 2012 e junho de 2013. Ao todo, 20 pacientes foram tratados com septoplastia endonasal com aplicação de EESC. O restante do grupo, que rejeitou coleta de cartilagem auricular ou costal para a aplicação de EESC, foi tratado apenas com septoplastia endonasal. Com a aplicação dos questionários Nose (Nasal Obstruction Symptom Evaluation, Avaliação dos Sintomas de Obstrução Nasal) e ROE (Rhinoplasty Outcome Evaluation, Avaliação dos Desfechos da Rinoplastia), as mensurações pré e pós-operatórias com o rinômetro acústico foram obtidas com o objetivo de avaliar o efeito da aplicação de EESC na obstrução nasal. Resultados No grupo controle, as áreas de secção transversal mínima (ASTM1) antes e depois da operação foram 0,44 ± 0,10 cm2 e 0,60 ± 0,11 cm2, respectivamente (p < 0,001). No grupo de estudo, os valores antes e depois da operação para ASTM1 foram 0,45 ± 0,16 cm2 e 0,67 ± 0,16 cm2, respectivamente (p < 0,01). No grupo controle, o valor para os volumes da cavidade nasal (VOL1) foi 1,71 ± 0,21 mL no pré-operatório e 1,94 ± 0,17 mL no pós-operatório (p < 0,001). No grupo de estudo, os VOL1 antes e depois da operação foram 1,72 ± 0,15 mL e 1,97 ± 0,12 mL, respectivamente (p < 0,001). A análise estatística dos valores pós-operatórios para ASTM1 e VOL1 nos grupos de estudo e controle não permitiu a detecção de qualquer diferença intergrupos (p = 0,093 e 0,432, respectivamente). No grupo de estudo e no grupo controle, os ângulos nasolabiais médios foram 78,15 ± 4,26º e 90,70 ± 2,38º, respectivamente (p < 0,001). Conclusão A septoplastia endonasal com aplicação de EESC é um procedimento cirúrgico efetivo, com mínimo percentual de complicações para pacientes que se apresentam com septo nasal curto e com desvio e com fraca sustentação da ponta do nariz.

Posición óptima para la nefrolitotomía percutánea en el riñón en herradura: ¿prono tradicional o supino? / Optimal patient position for percutaneous nephrolithotomy in horseshoe kidneys: Traditional prone or supine?

Objetivo: Aunque se ha afirmado que la nefrolitotomía percutánea (NLPC) en posición supina se asocia a tiempos quirúrgicos relativamente más cortos y a tasas de éxito y complicaciones comparables, no hay consenso en la literatura actual sobre la seguridad y la eficacia de la NLPC en posición supina en pacientes con riñón en herradura. Nuestro objetivo es comparar la NLPC en posición supina y en posición prona, en términos de seguridad y eficacia en pacientes con riñón en herradura.Métodos: Se revisaron retrospectivamente los datos de los pacientes con riñón en herradura sometidos a una NLPC por cálculos renales de más de 2cm entre enero de 2010 y mayo de 2021. Los pacientes del estudio se clasificaron como Grupo1 (NLPC en supino [SNLPC]) y Grupo2 (NLPC en prono [PNLPC]). Se compararon los datos demográficos, clínicos y quirúrgicos de los dos grupos.Resultados: Se incluyeron 65 pacientes, de los cuales 31 (47,7%) pertenecían al Grupo1 y 34 (52,3%) al Grupo2. Los datos demográficos, las características de los cálculos, los parámetros perioperatorios y las tasas de complicaciones fueron estadísticamente similares entre los dos grupos (p>0,05). No hubo diferencias estadísticas en cuanto a las tasas de tratamiento adicional y las tasas de ausencia de cálculos en los controles postoperatorios del segundo día y del tercer mes (p>0,05). El tiempo quirúrgico medio fue significativamente mayor en el Grupo2 (113±17,1minutos) que en el Grupo1 (90,6±11,3minutos) (p=0,000).Conclusión: Aunque tradicionalmente se realiza en posición prona, el abordaje en posición supina es similar en términos de seguridad y de eficacia. Además, la posición supina se asocia con tiempos quirúrgicos significativamente más cortos (AU)

Objective: Although it was stated that supine percutaneous nephrolithotomy (PCNL) was associated with relatively shorter surgical times and comparable success and complication rates, there is no consensus in the current literature concerning the safety and efficacy of supine PCNL in patients with horseshoe kidneys. We aimed to compare supine and prone PCNL regarding safety and efficacy in patients with horseshoe kidneys.Methods: Data of the patients with horseshoe kidneys who underwent PCNL for renal stones larger than 2cm between January 2010 and May 2021 were retrospectively reviewed. The study patients were categorized as Group1 (i.e., supine PCNL-SPCNL) and Group2 (i.e., prone PCNL-PPCNL). Both groups were compared regarding demographic, clinical, and surgical data.Results: Sixty-five patients were included. Among these patients, 31 (47.7%) were in Group1, while 34 (52.3%) were in Group2. Both groups were statistically similar in terms of demographic data, stone characteristics, perioperative parameters, and complication rates (P>.05). There was no statistical difference in terms of additional treatment rates, stone-free rates in the postoperative second-day and third-month evaluations (P>.05). Mean surgical time was significantly longer in Group2 (113±17.1minutes) than in Group1 (90.6±11.3minutes) (P=.000).Conclusion: Although it is traditionally performed in the prone position, the supine approach is as safe and effective as the prone approach. In addition, the supine approach is associated with significantly shorter surgical times (AU)

Can procalcitonin be a diagnostic marker for catheter-related blood stream infection in children? / A procalcitonina pode ser um marcador de diagnóstico de infecções de corrente sanguínea relacionadas a cateter em crianças?

Abstract Objective The potential role of procalcitonin (PCT) in the diagnosis of catheter-related bloodstream infection (CRBSIs) is still unclear and requires further research. The diagnostic value of serum PCT for the diagnosis of CRBSI in children is evaluated here. Method This study was conducted between October 2013 and November 2014, and included patients with suspected CRBSI from 1 month to 18 years of age who were febrile, with no focus of infection, and had a central venous catheter. Levels of PCT and other serum markers were measured, and their utility as CRBSI markers was assessed. Additionally, the clinical performance of a new, automated, rapid, and quantitative assay for the detection of PCT was tested. Results Among the 49 patients, 24 were diagnosed with CRBSI. The PCT-Kryptor and PCT-RTA values were significantly higher in proven CRBSI compared to those in unproven CRBSI (p = 0.03 and p = 0.03, respectively). There were no differences in white blood cell count and C-reactive protein (CRP) levels between proven CRBSI and unproven CRBSI. Among the 24 patients with CRBSI, CRP was significantly higher among those with Gram-negative bacterial infection than in those with Gram-positive bacterial infections. PCT-Kryptor was also significantly higher among patients with Gram-negative bacterial infection than in those with Gram-positive bacterial infections (p = 0.01 and p = 0.02, respectively). Conclusions The authors suggest that PCT could be a helpful rapid diagnostic marker in children with suspected CRBSIs.

Resumo Objetivo O possível papel da procalcitonina (PCT) no diagnóstico de infecções de corrente sanguínea relacionadas a cateter (ICSRCs) ainda não está claro e precisa ser mais pesquisado. O valor diagnóstico da PCT sérica para o diagnóstico de ICSRC em crianças é avaliado neste estudo. Método Este estudo foi feito entre outubro de 2013 e novembro de 2014 e incluiu pacientes com suspeita de ICSRC de um mês a 18 anos que estavam febris, não tinham foco de infecção e tinham cateter venoso central. Foram medidos os níveis de PCT e de outros marcadores séricos, cuja utilidade como marcadores de ICSRC foi avaliada. Adicionalmente, foi testado o desempenho clínico de um novo ensaio quantitativo automatizado e rápido para a detecção de PCT. Resultados Dentre 49 pacientes, 24 foram diagnosticados com ICSRC. Os valores de PCT-Kryptor e PCT-RTA foram significativamente maiores em ICSRCs comprovadas do que em ICSRCs não comprovadas (p = 0,03 e p = 0,03, respectivamente). Não houve diferença na contagem de glóbulos brancos e nos níveis de proteína C reativa (PCR) entre ICSRCs comprovadas e ICSRCs não comprovadas. Dentre os 24 pacientes com ICSRC, a PCR era significativamente maior entre aqueles com infecção bacteriana gram-negativa do que naqueles com infecção bacteriana gram-positiva. O PCT-Kryptor também foi significativamente maior entre pacientes com infecção por bactérias gram-negativas do que naqueles com infecção por bactérias gram-positivas (p = 0,01 e p = 0,02, respectivamente).

Is neutrophile to lymphocyte ratio a predictor of gleason score upgrading according to risk classifications in patients with prostate cancer / ¿Es la proporción de neutrófilos a linfocitos un predictor de la puntuación de Gleason?upgrading según clasificaciones de riesgo en pacientes conCancer de prostata

Objectives: We aimed to determine theparameters that predict Gleason Score (GS) upgradingin patients undergoing robot-assisted laparoscopic radical prostatectomy (RARP) and especially the ability ofneutrophile to lymphocyte ratio (NLR) in predicting theupgrading.Methods: Patients who underwent RARP for prostatecancer in our clinic between January 2013 and January2018 were retrospectively analyzed. Patients’ demographic data, preoperative and postoperative parameters were all recorded in the database. NLR was calculated by dividing the absolute neutrophil count (NC)by the absolute lymphocyte count (LC). Patients were classified as low, moderate and high risk according tothe National Comprehensive Cancer Network (NCNN)Guidelines. Any increase in GS between biopsy resultsand radical prostatectomy specimens were consideredas an GS upgrading.Results: After applying the inclusion and exclusion criteria, a total of 571 patients, 205 patients without GSupgrading (Group 1) and 366 patients with GS upgrading (Group 2), were included. The mean preoperativePSA values and prostate volumes were 10.8 ± 8 ng/dL and 45 ± 18.8 ml, respectively. Group 2 had asignificantly high NC and NLR, significantly low plateletcount (PC) and LC, (p=0.0001, 0.0001, 0.001 and0.002, respectively). Group 2 was found to have significantly higher positive surgical margin (PSM), extraprostatic extension (EPE) and seminal vesical invasion(SVI) (p<0.001). There was no significant correlation between the parameters of NLR and PSM, EPE, SVI, andlymph node invasion (LNI). Binomial logistic regressionshowed patients with increased NLR had 1.68 timeshigher odds to exhibit an upgrade in GS in the post-surgical histopathological analysis.Conclusions: NLR calculated preoperatively is aneasy diagnostic method that can predict GS upgradingin patients scheduled for radical prostatectomy for prostate cancer.(AU)

Objetivo: Determinamos los parámetros que predicen el grado de sobregradación deGleason en pacientes que recibieron prostatectomíaradical robótica asistida por laparoscopia (PRRL) yespecialmente la habilidad de la tasa de neutrófilos/linfocitos (NLR) a la hora de predecir la sobregradación.Métodos: Los pacientes que recibieron PRRL por cáncer de próstata en nuestra clínica entre enero 2013y enero de 2018 se analizaron retrospectivamente.Los datos demográficos, parámetros preoperatorios ypostoperatorios fueron reportados en la base de datos. NLR se calculo dividiendo el numero absoluto deneutrófilos (NC) por el numero absoluto de linfocitos(LC). Los pacientes se clasificaron como bajo, moderado y alto riesgo en la relación a las guías de NationalComprehensive Cancer Network (NCNN). Cualquieraumento en el grado de Gleason entre los resultadosde la biopsia y la prostatectomía radical fueron considerados como una sobregradación de grado deGleason.Resultados: Después de aplicar los criterios de inclusión y exclusión, un total de 571 pacientes, 205sin sobregradación de Gleason (Grupo 1) y 366 pacientes con sobregradación de Gleason (Grupo 2).La media de PSA preoperatorio y volúmenes prostáticos fueron de 10,8 ± 8 ng/dL y 45 ± 18,8 ml, respectivamente. El grupo 2 presentó un NC y NLR másalto, significativamente, bajos niveles de plaquetas yLC (p=0,0001, 0,0001, 0,001 y 0,002, respectivamente). El grupo 2 demostró tener niveles significativamente más altos de márgenes quirúrgicos (PSM),extensión extraprostatica (EPE) e invasión de vesículasseminales (SVI) (p<0,001). No se encontró una correlación significativa entre los parámetros de NLR yPSM, EPE, SVI, invasión ganglios linfáticos. El modelode regresión binomial logística demostró que los pacientes con un incremento de NLR tuvieron 1,68 másveces de tener una sobregradación de Gleason en elanálisis histopatológico postquirúrgico...(AU)

Turkish teachers' self-efficacy to manage food allergy and anaphylaxis: A psychometric testing study

Introduction and objectives: Food allergy in school children ranges between 5.7 and 6.4% in Turkey. Studies emphasize the importance of improving school personnel's self-efficacy in managing food allergy and anaphylaxis. However, a brief and valid measurement tool for school personnel is not available in Turkey. The aim of this study was to determine the validity and reliability of the Turkish version of the School Personnel's Self-efficacy in Managing Food Allergy and Anaphylaxis (SPSMFAA-T) scale with teachers. Patients or materials and methods: This methodological study was conducted by 282 primary school teachers. Data were collected with a demographic characteristics form and SPSMFAA-T. The psychometric properties of the SPSMFAA-T were evaluated by content, discriminant, construct validity and internal consistency. Results: Cronbach's alpha for the scale was 0.91 and item-total correlations were between 0.50 and 0.82 (p < 0.001). The discriminant validity suggested that the scale successfully discriminated the teachers who had training on food allergy and anaphylaxis from the teachers who did not. The model fit indices of scale were determined to be the root mean square error of approximation (RMSEA) at 0.08, goodness of fit index (GFI) at 0.96, comparative fit index (CFI) at 0.99. Conclusions: The results supported that the SPSMFAA-T was a valid and reliable measurement tool to assess Turkish teachers’ self-efficacy levels to manage food allergy and anaphylaxis in school setting. The scale can be used in education programs to improve school personnel's skills to manage food allergy and anaphylaxis
