Abstract Background: Chronic Spontaneous Urticaria (CSU) is characterized by recurrent wheals and/or angioedema for longer than 6-weeks. Guidelines recommend Omalizumab (Oma) as first-line and Cyclosporine-A (Cs-A) as second-line treatment in antihistamine resistant CSU. This step-wise algorithm might be time-consuming and costly. Objective: To determine indicators of response to Oma or Cs-A in CSU patients. Methods: We retrospectively analyzed data from seven centers in Turkey; the inclusion criteria for patients were to receive both Oma and Cs-A treatment (not concurrently) at some point in time during their follow-up. Clinical and laboratory features were compared between groups. Results: Among 110 CSU patients; 47 (42.7%) were Oma-responders, 15 (13.6%) were Cs-A-responders, and 24 (21.8%) were both Oma and Cs-A responders and 24 (21.8%) were non-responders to either drug. High CRP levels were more frequent in Cs-A-responders (72.7% vs. 40.3%; p = 0.055). Oma-responders had higher baseline UCT (Urticaria Control Test) scores (6 vs. 4.5; p = 0.045). Responders to both drugs had less angioedema and higher baseline UCT scores compared to other groups (33.3% vs. 62.8%; p = 0.01 and 8 vs. 5; p = 0.017). Non-responders to both drugs had an increased frequency in the female gender and lower baseline UCT scores compared to other groups (87.5% vs. 61.6%; p = 0.017 and 5 vs. 7; p = 0.06). Study Limitations: Retrospective nature, limited number of patients, no control group, the lack of the basophil activation (BAT) or BHRA (basophil histamine release assay) tests. Conclusions: Baseline disease activity assessment, which considers the presence of angioedema and disease activity scores, gender, and CRP levels might be helpful to predict treatment outcomes in CSU patients and to choose the right treatment for each patient. Categorizing patients into particular endotypes could provide treatment optimization and increase treatment success. © 2022 Published by Elsevier España, S.L.U. on behalf of Sociedade Brasileira de Dermatologia.

Abstract Introduction Increases in spontaneous activity in the neurons of the auditory cortex are presumed as the pathophysiology of tinnitus. Objective To investigate the effectiveness of transcranial magnetic stimulation (TMS) in the treatment of tinnitus. Methods A total of 62 patients between the ages of 22 and 74 with chronic subjective tinnitus were enrolled in the study. The inclusion criteria were normal findings on an otolaryngologic examination and normal ranges of complete blood count, routine biochemical parameter levels, thyroid function, air-bone gap on pure-tone audiometry, and middle-ear pressure and stapedial reflex on tympanometry. The patients were randomized into 2 groups: 40 patients were placed in the treatment for TMS (tTMS) group, and the rest (22 patients) were placed in the sham TMS group. The frequency and severity of the tinnitus, as well as the tinnitus handicap inventory (THI) score of each patient were measured before and one month after the treatment, and the values were statistically evaluated. Results We observed a statistically significant improvement in the tTMS group (p< 0.05 and p< 0.05 respectively) regarding the THI and tinnitus severity scores. The sham TMS group showed no significant improvement in terms of the THI (p> 0.05). However, the tinnitus severity showed a significant increase in this group (p< 0.05). The comparison of differences in the changes in the THI and the tinnitus severity scores showed a significant statistical improvement in the tTMS group compared with the sham TMS group (p< 0.05 and p< 0.05 respectively). Conclusion Transcranial magnetic stimulation was found to be effective in the treatment of tinnitus, and may be adopted as a treatment for tinnitus after further comprehensive studies.

Abstract Background Comparative data on the performance of cardiovascular risk scoring systems (CRSSs) in patients with severe coronary artery disease (CAD) are lacking. Objectives To compare different CRSSs regarding their ability to discriminate patients with severe CAD. Method A total of 414 patients (297 men; 61.3±12.3 years of age) undergoing coronary angiography were enrolled and evaluated for major risk factors. Cardiovascular risk and risk category were defined for each patient using the Framingham, Systemic Coronary Risk Evaluation (SCORE), and Pooled Cohort Risk Assessment Equation (PCRAE) tools. Severe CAD was defined as ≥ 50% stenosis in at least one major coronary artery and/or previous coronary stenting or coronary artery bypass grafting. A p < 0.05 was considered statistically significant. Results Severe CAD was identified in 271 (65.4%) patients. The ROC curves of the 3 CRSSs for predicting severe CAD were compared and showed no significant difference: the area under the ROC curve was 0.727, 0.694, and 0.717 for the Framingham, SCORE, and PCRAE tools, respectively (p > 0.05). However, when individual patients were classified as having low, intermediate, or high cardiovascular risk, the rate of patients in the high-risk group was significantly different between the PCRAE, Framingham, and SCORE tools (73.4%, 27.5%, and 37.9%, respectively; p < 0.001). Discussion PCRAE had higher positive and negative predictive values for detecting severe CAD in high-risk patients than the Framingham and SCORE tools. Conclusion We can speculate that currently used CRSSs are not sufficient, and new scoring systems are needed. In addition, other risk factors, such as serum creatinine, should be considered in future CRSSs. Int J Cardiovasc Sci. 2020; [online].ahead print, PP.0-0

SUMMARY OBJECTIVE: We aimed to compare the clinical, epidemiological, and prognostic features of the H1N1 pandemic in 2009 and the severe acute respiratory syndrome coronavirus 2 pandemic in 2020. METHODS: This retrospective study involved subjects from seven centers that were admitted and found to be positive for H1N1 or COVID-19 real-time polymerase chain reaction test. RESULTS: A total of 143 patients with H1N1 and 309 patients with COVID-19 were involved in the study. H1N1 patients were younger than COVID-19 ones. While 58.7% of H1N1 patients were female, 57.9% of COVID-19 patients were male. Complaints of fever, cough, sputum, sore throat, myalgia, weakness, headache, and shortness of breath in H1N1 patients were statistically higher than in COVID-19 ones. The duration of symptoms until H1N1 patients were admitted to the hospital was shorter than that for COVID-19 patients. Leukopenia was more common in COVID-19 patients. C-reactive protein levels were higher in COVID-19 patients, while lactate dehydrogenase levels were higher in H1N1 ones. The mortality rate was also higher in H1N1 cases. CONCLUSIONS: The severe acute respiratory syndrome coronavirus 2 pandemic is a major public health problem that continues to affect the world with its high rate of contagion. In addition, no vaccines or a specific drug for the benefit of millions of people have been found yet. The H1N1 pandemic is an epidemic that affected the whole world about ten years ago and was prevented by the development of vaccines at a short period. Experience in the H1N1 pandemic may be the guide to prevent the COVID-19 pandemic from a worse end.

Abstract: Black pine (Pinus nigra) is a significant raw material source for the forest products industry in Turkey. The purpose of this research was to study some chemical, anatomical, physical, and mechanical properties of wood obtained from juvenile black pines planted in Kavaklıdere - Muğla, originating from five different locations: Muğla, Balıkesir, Denizli, Bursa, and Kütahya. Although pines originating from Muğla and Balıkesir were good in terms of wood properties, those from Denizli, Bursa, and Kütahya exhibited no remarkable features. Black pine of Muğla origin was recommended for planting in Kavaklıdere and similar habitats, whereas pines of Denizli, Bursa, and Kütahya origins were not recommended. However, pine of Balıkesir origin may be an alternative to that of Muğla origin for black pine plantations at Kavaklıdere and similar sites.

OBJECTIVES: Progressive renal disease is characterized by histological changes in the kidney and fibrosis is a common outcome. Renal biopsy is the only diagnostic tool to evaluate these histopathological changes. Pentraxin-2 (PTX-2) is an anti-inflammatory constitutive plasma protein associated with the innate immune system. Recently, as a biomarker, the circulating level of PTX-2 is shown to be decreased in chronic fibrotic diseases. In this study, we aimed to investigate the relationship between renal fibrosis severity and serum PTX-2 levels in patients undergoing renal biopsy. METHODS: This cross-sectional study included 45 patients and 16 healthy individuals (HIs). The severity of renal fibrosis was evaluated according to the Banff and Sethi scoring systems by the same pathologist. PTX-2 was measured by an enzyme-linked immunosorbent assay and compared with the demographical, clinical, biochemical, and histopathological data of the patients and HIs. RESULTS: PTX-2 levels were lower in the biopsy group than in the HI group (p=0.12). Patients with moderate renal fibrosis had significantly lower serum PTX-2 levels than those in patients with minimal and mild fibrosis (p=0.017 and p=0.010, respectively). PTX-2 concentrations were correlated with serum albumin (r=0.30, p=0.016), and were negatively correlated with serum creatinine levels (rho=-0.42, p=0.01) and body mass index (r=-0.32, p=0.011). CONCLUSIONS: The results indicated that PTX-2 levels are significantly lower in patients with renal fibrosis than HIs, and declining further in patients with severe fibrosis.

ABSTRACT Objective We aimed to evaluate the results of laparoscopic pyeloplasty with concomitant pyelolithotomy and compare results with a cohort of patients undergoing laparoscopic pyeloplasty without pyelolithotomy. Materials and Methods We retrospectively reviewed records of 43 patients undergoing transperitoneal laparoscopic Anderson-Hynes dismembered pyeloplasty between December 2012 and July 2018 at our department. Eighteen patients (42%) underwent laparoscopic pyeloplasty with concomitant pyelolithotomy. The results of patients with renal stones were compared with 25 matched patients undergoing laparoscopic pyeloplasty without concomitant renal stones. Demographic data, operative and stone parameters were compared between the groups. Results The groups were similar regarding to demographic characteristics. All operations were completed laparoscopically with no conversions to open surgery. In 3 cases without renal stones and 15 cases with renal stones, transposition of the ureter due to crossing vessels was performed. The mean stone size was 13±5.24 mm, and the median number of stones was 1 (1-18). The success of laparoscopic pyeloplasty with and without pyelolithotomy was 93.3% and 92.9%, respectively, as confirmed by negative diuretic renogram at postoperative 3rd months. Overall stone-free rate after laparoscopic pyelolithotomy was 93.3%. Mean operative time was 222.6765.71 minutes vs. 219.11±75.63 minutes for the pyeloplasty with concomitant pyelolithotomy vs. pyeloplasty, respectively (p=0.88). Conclusions Laparoscopic pyeloplasty with concomitant pyelolithotomy is a safe and effective intervention with associated good cosmetic results and high stone-free rates without significant increase in operative time or complications.

RESUMO Objetivo: Avaliar escores de joelho, resultados da avaliação radiológica, correção de déficits, alteração da altura patelar, tempo de consolidação óssea e tempo para apoio de peso no pós-operatório em pacientes submetidos à osteotomia tibial alta (OTA) com ou sem enxerto autólogo de osso ilíaco. Métodos: O exame retrospectivo de controles tratados em estudo randomizado e controlado foi realizado em 63 joelhos de 58 pacientes com idade entre 46 e 59 anos submetidos a OTA com placas bloqueadas de titânio em cunha aberta. Os pacientes foram divididos em dois grupos: Grupo A, OTA com enxerto de osso ilíaco autólogo (n = 31) e Grupo B, OTA sem enxerto autólogo de osso ilíaco (n = 32). Os dados clínicos e radiológicos foram avaliados prospectivamente na consulta pré-operatória e 6, 9 e 12 semanas e 6 meses e 1 ano após a cirurgia (e depois disso, anualmente). Resultados: Não houve diferenças significativas quanto a avaliação radiológica, correção de déficit, mudança de altura da patela, tempo de cicatrização óssea e tempo para apoio de peso entre os dois grupos em nenhum momento após a cirurgia. Os escores de joelho mudaram positivamente em ambos os grupos (p < 0,001). Conclusões: Não houve diferença nos resultados dos pacientes submetidos a OTA com placas bloqueadas de titânio em cunha aberta com e sem autoenxerto, e as comorbidades resultantes dos autoenxertos foram eliminadas com o uso de placas bloqueadas. Nível de Evidência III, Estudo Retrospectivo.

ABSTRACT Objective: To postoperatively evaluate knee scores, radiological assessment results, deficit correction, patellar height change, bone healing time, and weight bearing time in patients undergoing high tibial osteotomy (HTO) with/without autologous iliac bone grafting. Methods: This retrospective examination of treated controls from a randomized controlled study included 63 knees of 58 patients aged 46–59 years who underwent HTO with locking open wedge osteotomy plates. The patients were divided into two groups: Group A, HTO with autologous iliac bone grafts (n = 31); and Group B, HTO without autologous iliac bone grafts (n = 32). Clinical and radiological data were evaluated prospectively at the preoperative consultation and again at 6, 9, and 12 weeks, 6 months, and 1 year after the surgery (and annually thereafter). Results: There were no significant intergroup differences in the radiological assessment, deficit correction, patellar height change, bone-healing time, and weight-bearing time at any time after surgery. The knee scores changed positively in both groups (p < 0.001). Conclusions: There was no difference in the results of patients undergoing HTO with open wedge osteotomy titanium locking plates with or without autografting, and comorbidities resulting from autografts were eliminated with the use of locking plates. Level of evidence III, Retrospective Study.

RESUMO Nosso paciente era um homem de 34 anos que apresentou uma massa conjuntival indolor desde há 3 meses antes da primeira consulta. Na biomicroscopia por lâmpada de fenda, observa-se uma massa rosa-amarelada, sólida, móvel e lobulada na superfície conjuntival bulbar nasal, em seu olho esquerdo. O tumor foi retirado e o exame histopatológico demonstrou um adenoma sebáceo. O exame sistêmico era normal. Nenhuma recidiva foi observada durante os 24 meses de acompanhamento. Adenoma sebáceo da conjuntiva bulbar é um tumor benigno extremamente raro e pode ser visto isolado, sem quaisquer doenças malignas associadas.

ABSTRACT Our patient was a 34 year-old male who presented with a painless conjunctival mass that had developed 3 months before his first visit. On performing slit-lamp biomicroscopy, a lobulated pink-yellowish solid mobile mass was observed on the nasal bulbar conjunctival surface of his left eye. The tumor was excised, and histopathologic examination of the tumor revealed a sebaceous adenoma. Systemic examination was normal. No recurrence was observed during the 24-month follow-up period. Sebaceous adenoma of the bulbar conjunctiva is an extremely rare benign tumor, which may be observed to be isolated in the absence of malignancy.

This study reports tympanic cavity (TC) volume in newborns, which was missing in the literature. Ex vivo histology and computerized tomography (CT) scans were performed on temporal bone and data were analyzed in part using software developed in house. CT images with a slice thickness of 0.5 mm were obtained from 5 newborn cadavers and analyzed independently by two expert researchers. The border of the TC was delineated manually and measurement of area of interest was calculated on masked images. Then, the area measurements from all sections were added to estimate the total volume. The agreements between the histological and CT findings were then compared for accuracy, repeatability and reliability. The Dice and Jaccard similarity coefficient measures were used as a statistical validation metric to evaluate the assessor's performance in manual volume segmentation. Good assessor agreement was observed with average Dice values above 0.8 indicating that consistent and reliable volume measurements were feasible. The proposed protocol was shown to be accurate in calculating the TC volume, and thus can be used for computer-assisted presurgical planning or for diagnosing structural alterations in TC.

El objetivo fue determinar el volumen de la cavidad timpánica (CT) en recién nacidos, información no encontrada en la literatura. Se realizaron escaners a través de tomografia computadorizada (TC) y estudios histológicos en el hueso temporal; los datos se analizaron utilizando un software desarrollado en nuestra institución. Se obtuvieron imágenes de secciones de TC, de 0,5 mm de grosor, a partir de 5 cadáveres de recién nacidos, los que fueron analizados de forma independiente por dos investigadores expertos. El margen de los cortes de TC fue delineado manualmente y la medición del área de interés se estimó sobre imágenes ocultas. Después, se añadieron las mediciones de área de todas las secciones para estimar el volumen total. Las concordancias entre el estudio histológico y los hallazgos de la TC se compararon en cuanto a precisión, repetibilidad y confiabilidad. Se utilizaron las medidas de coeficiente de similitud de Jaccard y Dice como métrica de validación estadística para evaluar el desempeño del asesor en la medición manual del volumen. Se observó una buena correlación del evaluador con los valores medios de Dice, por encima de 0,8 indicando que es factible obtener mediciones coherentes y confiables de volumen. El protocolo propuesto ha demostrado ser preciso para calcular el volumen de la CT, y por lo tanto se puede utilizar para la planificación prequirúrgica asistida o para el diagnóstico de alteraciones estructurales en la CT.

JUSTIFICATIVA E OBJETIVOS: A dor relacionada ao torniquete é um dos maiores obstáculos para a anestesia regional intravenosa (ARIV). Nosso objetivo foi comparar tramadol e lornoxicam usados em ARIV em relação aos seus efeitos sobre a qualidade da anestesia, dor relacionada ao torniquete e dor no pós-operatório. MÉTODOS: Após a aprovação do Comitê de Ética, 51 pacientes com estado físico ASA I-II entre 18-65 anos foram inscritos. Os pacientes foram divididos em três grupos. Grupo P (n = 17) recebeu 3 mg/kg de prilocaína a 0,5%; Grupo PT (n = 17) 3 mg/kg de prilocaína a 0,5% + 2 mL (100 mg) de tramadol e Grupo PL (n = 17) de 3 mg/kg de prilocaína a 0,5% + 2 mL (8 mg) de lornoxicam para ARIV. O início do bloqueio sensorial e motor e os tempos de recuperação foram registrados, bem como a dor relacionada ao torniquete e o consumo de analgésico no pós-operatório. RESULTADOS: Os tempos de início do bloqueio sensorial foram mais curtos nos grupos PT e PL, enquanto que os tempos de recuperação correspondentes foram mais longos do que os do Grupo P. Os tempos de início do bloqueio motor nos grupos PT e PL foram menores do que no Grupo P, enquanto que o tempo de recuperação do grupo PL foi maior do que os dos grupos P e PT. O tempo para início da dor relacionada ao torniquete foi menor no Grupo P e maior no Grupo PL. Não houve diferença em relação à dor relacionada ao torniquete entre os grupos. O Grupo PL apresentou o menor consumo de analgésicos no pós-operatório. CONCLUSÃO: A adição de tramadol e lornoxicam à prilocaína para ARIV produz efeitos favoráveis sobre o bloqueio sensorial e motor. O consumo de analgésicos no pós-operatório pode ser reduzido com a adição de tramadol e lornoxicam à prilocaína em ARIV.

BACKGROUND AND OBJECTIVES: Tourniquet pain is one of the major obstacles for intravenous regional anesthesia. We aimed to compare tramadol and lornoxicam used in intravenous regional anesthesia as regards their effects on the quality of anesthesia, tourniquet pain and postoperative pain as well. METHODS: After the ethics committee approval 51 patients of ASA physical status I-II aged 18-65 years were enrolled. The patients were divided into three groups. Group P (n = 17) received 3 mg/kg 0.5% prilocaine; group PT (n = 17) 3 mg/kg 0.5% prilocaine + 2 mL (100 mg) tramadol and group PL (n = 17) 3 mg/kg 0.5% prilocaine + 2 mL (8 mg) lornoxicam for intravenous regional anesthesia. Sensory and motor block onset and recovery times were noted, as well as tourniquet pains and postoperative analgesic consumptions. RESULTS: Sensory block onset times in the groups PT and PL were shorter, whereas the corresponding recovery times were longer than those in the group P. Motor block onset times in the groups PT and PL were shorter than that in the group P, whereas recovery time in the group PL was longer than those in the groups P and PT. Tourniquet pain onset time was shortest in the group P and longest in the group PL. There was no difference regarding tourniquet pain among the groups. Group PL displayed the lowest analgesic consumption postoperatively. CONCLUSION: Adding tramadol and lornoxicam to prilocaine for intravenous regional anesthesia produces favorable effects on sensory and motor blockade. Postoperative analgesic consumption can be decreased by adding tramadol and lornoxicam to prilocaine in intravenous regional anesthesia.

Objetivo: Investigar a espessura da coroide em gestantes saudáveis durante os diferentes trimestres utilizando tomografia de coerência óptica com profundidade de imagem aprimorada (EDI-OCT). Métodos: Este estudo prospectivo incluiu 90 gestantes saudáveis nos primeiro, segundo e terceiro trimestres da gravidez (grupos 1, 2 e 3, respectivamente) e 30 mulheres saudáveis não-gestantes (grupo 4) com faixa etária de 18-40 anos de idade. Foi realizada tomografia de coerência óptica espectral para estimar a espessura média da coroide. A espessura da coroide foi medida manualmente da borda externa do epitélio pigmentar da retina até o limite interno da esclera nas regiões subfoveal, 3 mm temporal e 3 mm nasal à fóvea utilizando EDI-OCT. As diferenças entre os grupos foram analisadas com o teste ANOVA unicaudal. Resultados: Houve diferença estatística significativa na espessura média da coroide entre os grupos 2 e 4 nas regiões subfoveal, temporal e nasal à fóvea (p=0,007; p<0,001; p=0,026, respectivamente). A espessura média da coroide no grupo 2 foi: 395 ± 80 µm, 338 ± 77 µm e 233 ± 61 µm nas regiões subfoveal, temporal e nasal à fóvea, respectivamente. Em comparação, a espessura média da coroide no grupo 4 foi de: 335 ± 86 µm, 275 ± 54 µm e 200 ± 53 µm, nas regiões subfoveal, temporal e nasal à fóvea, respectivamente. Não foi encontrada diferença estatística significativa entre os grupos 1-4 (p=0,214, p=0,177, p=0,094, respectivamente) e os grupos 3-4 (p=0,105, p=0,261, p=0,695 respectivamente), para todas as medidas. Conclusão: Nossos resultados sugerem que há espessamento da coroide nas regiões subfoveal, temporal e nasal à fóvea no segundo trimestre gestacional.
