Polyp in concha bullosa: a case report and review of the literature

Polyp originating within a concha bullosa is uncommon; we report only the third such case in the English literature. A 45-year-old man presented with nasal obstruction and headache. Examination of the nose revealed right septal deviation and a hypertrophic left middle concha. Computed tomography confirmed right septal deviation and identified left concha bullosa with thickening of the mucosa covering this lesion. The lateral lamella of the affected turbinate was removed and a mass was excised. Histopathologic examination of the excised mass revealed polypoid hyperplasia. The rare finding of polyp in concha bullosa is discussed with a review of the literature. In any case of concha bullosa, computed tomography images should be carefully evaluated before surgery to check for other pathologies that might have arisen within the lesion

Primary Sjogren Syndrome: Case report

The importance of systemic evaluation of dry eye patients and choosing appropriate treatment based on the severity of disease were emphasized with this case. 48 years old woman complained about decreased vision, burning, itching in both eyes which got worse over the years, for about 20 years. Schirmer I test value was 0 mm/5min in both eyes. Slit lamp examination revealed filamentary keratitis in both eyes. Anti-Ro/ SSA, anti-La/ SS-B antibodies and salivary gland biopsy for Sjogren syndrome were positive. Temporary punctal occlusion and oral hydroxychloroquine were added to her treatment. After 10 days, her overall dry eye condition improved and permanent punctual plugs were inserted in both lower puctums.Dry eye patients should be evaluated systemically and severity of disease should be considered before treatment is started. Addition to topical application of artificial tears, punctal occlusion may be a proper option in dry eye patients with Sjogren syndrome. [Cukurova Med J 2013; 38(4.000): 818-822

Prognostic and predictive role of FOXP3 positive tumor infiltrating lymphocytes (TILs) in curatively resected non small cell lung cancer other than stage IA

Lung cancer is the leading cause of cancer-related mortality and responsible for 1.6 million deaths per year through world-wide. Surgical resection with negative margin combined with the adjuvant therapy [except for stage IA and IB (<4 cm)] is the Standard treatment for early-stage Non-small cell lung cancer (NSCLC). Early-stage NSCLC, however, has relapse rate over 40% mostly at distant sites. Therefore, high relapse rate necessitates urgent novel biomarker for these patients. In this study, we aim to evaluate the predictive and prognostic role of FOXP3+ Treg cells along with well defined Clinicohistopathological factors in early-stage non-small cell lung cancer (NSCLC). FOXP3 expression in tumor infiltrating lymphocytes (TIL) was examined by immunohistochemical staining from resected early-stage 48 NSCLC patients. Data of patients and FOXP3 expression status along with common clinicohistopathological prognostic factors were evaluated retrospectively. Median age of patients was 62 years-old (range 43–78). Mean follow-up, median overall survival (OS), and disease-free survival (DFS) were 49, 49 and 30 months, respectively. FOXP3 expression was positive in 23 (47.9%) patients. Adjuvant chemotherapy (4 cycles of cisplatin-vinorelbine) was given to 16 patients (33.3%) at physician discretion. Patients with a FOXP3 expression of 25% or higher significantly lower OS and DFS when compared with patients with a FOXP3 staining lower than 25% with p-value of 0.016 and 0.032, respectively. In the patients with high FOXP3 expression, platin-based adjuvant chemotherapy had showed a detrimental effect on DFS and OS. These results suggest that FOXP3 expression may be used as useful prognostic biomarker in resected NSCLC. Our findings also suggest that resected NSCLC patients with FOXP3 expression of 25% or higher staining intensity may not get any benefit even disfavor from adjuvant platin chemotherapy

Sirolimus is effective and safe in childhood relapsed-refractory autoimmune cytopenias: A multicentre study

Autoimmune cytopenias are a heterogeneous group of disorders characterized by immune-mediated destruction of haematopoietic cell lines. Effective and well-tolerated treatment options for relapsed-refractory immune cytopenias are limited. In this study, the aim was to evaluate the efficacy and safety of sirolimus in this disease group within the paediatric age group. The study enrolled patients in the paediatric age group who used sirolimus with a diagnosis of immune cytopenia between December 2010 and December 2020, followed at six centres in Turkey. Of the 17 patients, five (29.4%) were treated for autoimmune haemolytic anaemia (AIHA), six (35.2%) for immune thrombocytopenic purpura (ITP) and six (35.2%) for Evans syndrome (ES). The mean response time was 2.7 months (range, 0–9 months). Complete response (CR) and partial response (PR) were obtained in 13 of 17 patients (76.4%) and nonresponse (NR) in four patients (23.5%). Among the 13 patients who achieved CR, three of them were NR in the follow-up and two of them had remission with low-dose steroid and sirolimus. Thus, overall response rate (ORR) was achieved in 12 of 17 patients (70.5%). In conclusion, sirolimus may be an effective and safe option in paediatric patients with relapsed-refractory immune cytopenia

Thrombolysis with Systemic Recombinant Tissue Plasminogen Activator in Children: A Multicenter Retrospective Study

Objective: This study aimed to evaluate systemic thrombolysis experiences with recombinant tissue plasminogen activator (rtPA). Materials and Methods: Retrospective data were collected from 13 Turkish pediatric hematology centers. The dose and duration of rtPA treatment, concomitant anticoagulant treatment, complete clot resolution (CCR), partial clot resolution (PCR), and bleeding complications were evaluated. Low-dose (LD) rtPA treatment was defined as 0.01-0.06 mg/kg/h and high-dose (HD) rtPA as 0.1-0.5 mg/kg/h. Results: Between 2005 and 2019, 55 thrombotic episodes of 54 pediatric patients with a median age of 5 years (range: 1 day to 17.75 years) were evaluated. These patients had intracardiac thrombosis (n=16), deep vein thrombosis (DVT) (n=15), non-stroke arterial thrombosis (n=14), pulmonary thromboembolism (PE) (n=6), and stroke (n=4). The duration from thrombus detection to rtPA initiation was a median of 12 h (range: 2-504 h) and it was significantly longer in cases of DVT and PE compared to stroke, non-stroke arterial thrombosis, and intracardiac thrombosis (p=0.024). In 63.6% of the episodes, heparin was initiated before rtPA treatment. LD and HD rtPA were administered in 22 and 33 of the episodes, respectively. Concomitant anticoagulation was used in 90% and 36% of the episodes with LD and HD rtPA, respectively (p=0.0001). Median total duration of LD and HD rtPA infusions was 30 h (range: 2-120 h) and 18 h (2-120 h), respectively (p=0.044). Non-fatal major and minor bleeding rates were 12.5% and 16.7% for LD and 3.2% and 25.8% for HD rtPA, respectively. At the end of the rtPA infusions, CCR and PCR were achieved in 32.7% and 49.0% of the episodes, respectively. The most successful site for thrombolysis was intracardiac thrombosis. HD versus LD rtPA administration was not correlated with CCR/PCR or bleeding (p>0.05). Conclusion: Systemic thrombolytic therapy may save lives and organs effectively if it is used at the right indications and the right times in children with high-risk thrombosis by experienced hematologists with close monitoring of recanalization and bleeding

Castleman Disease: A Multicenter Case Series from Turkey

Objective: Castleman disease (CD) is a rare disease also known as angiofollicular lymph node hyperplasia. The two main histological subtypes are the hyaline vascular and plasma cell variants. It is further classified as unicentric CD (UCD) or multicentric CD (MCD) according to the anatomical distribution of the disease and the number of lymph nodes involved. The aim of this multicenter study was to evaluate all cases of CD identified to date in Turkey to set up a national registry to improve the early recognition, treatment, and follow-up of CD. Materials and Methods: Both adult (n=130) and pediatric (n=10) patients with lymph node or involved field biopsy results reported as CD were included in the study. Patients’ demographic information, clinical and laboratory characteristics, imaging study results, treatment strategies, and clinical outcomes were evaluated retrospectively. Results: A total of 140 patients (69 male and 71 female) with a diagnosis of UCD (n=73) or MCD (n=67) were included. The mean age was 39 years in the UCD group and 47 years in the MCD group. Female patients were more common in the UCD group. The most common histological subtype was hyaline vascular for both UCD and MCD patients. Asymptomatic patients were more common in the UCD group. Anemia, elevations of acute phase reactants, and hypoalbuminemia were more common in the MCD group. The most commonly used treatment strategies for UCD were surgical excision, rituximab, and radiotherapy, respectively. All UCD patients were alive at a median of 19.5 months of follow-up. The most commonly used treatment strategies for MCD were methyl prednisolone, R-CHOP, R-CVP, and rituximab. Thirteen MCD patients had died at a median of 34 months of follow-up. Conclusion: This study is important in presenting the patient characteristics and treatment strategies for CD from Turkey, with the potential of increasing awareness about CD. Treatment data may help in making decisions, particularly in countries that do not have access to siltuximab. However, larger prospective studies are needed to make definitive conclusions. © 2022 by Turkish Society of Hematology.Türk Hematoloji Derneğisupported by the Turkish Society of Hematology
