Bilateral multiple tumor-like endobronchial tuberculosis, diagnosed with bronchoscopic examination

Endobronchial tuberculosis is defined as tuberculosis infection of tracheobronchial tree and it is not seen often in adult population. In the absence of parenchymal disease endobronchial tuberculosis is less well-recognized and can lead to difficulties in diagnosis. Our aim is to introduce a rare form of tuberculosis that is important because of high probability of developing severe bronchostenosis during its course. We report a 20-year-old woman who presented with two-month history of severe non-productive cough, shortness of breath, and hemoptysis. After clinical and radiological evaluation, flexible bronchoscopy showed bilateral multiple tumorous lesions that were seen from main carina down to the both main bronchus. The biopsy samples revealed EBTB diagnosis and antituberculosis therapy was given. At the second month of the therapy, rebronchoscopy revealed almost disappearance of the polypoid lesions. The patient healed without any stenosis. This case report is a reminder that endobronchial tuberculosis must take into consideration in differential diagnosis of endobronchial lesions. In patients with endobronchial tuberculosis healing without any complication could be achieved with timely diagnosis and commencement of early treatment.     

Ambulatory Blood Pressure Monitoring and Echocardiographic Findings in Renal Transplant Recipients

Hypertension is common in renal transplant recipients (RTRs). Ambulatory blood pressure (BP) monitoring (ABPM) is important in diagnosing hypertension and diurnal BP variation. The authors set out to compare office BP and ABPM measurements to determine diurnal pattern and to evaluate echocardiographic findings in RTRs. ABPM and office BP measurements were compared in 87 RTRs. Echocardiographic evaluation was performed for each patient. The correlations between office and 24‐hour ABPM were 0.275 for mean systolic BP (P=.011) and 0.260 for mean diastolic BP (P=.017). Only 36.8% had concordant hypertension between office BP and ABPM, with a masked hypertension rate of 16.1% and white‐coat effect rate of 24.1%. Circadian BP patterns showed a higher proportion of nondippers (67.8%). Left ventricular mass index was increased in 21.8% of all recipients. There was a significant but weak correlation between office BP and ABPM.     

Patient companions in the Turkish healthcare system: the role,expectations and problems

The purpose of this study was to determine the roles, expectations and problems of patient companions and to develop solutions to the difficulties encountered by the nurses, patients and their companions. A qualitative approach with semi‐structured face‐to‐face interviews was used during May and June 2014 to collect data. A convenience sample of participants was selected from the nurses, patients and their companions. Content analysis was used for the data. The results of this study revealed that the need for companions is important to the current Turkish healthcare system, but it has many drawbacks. As companions are witness to a patient's declining health and family, social and financial problems, their role should be to support their patients emotionally or socially, but they should not perform medical tasks. Therefore, the agencies responsible for managing the use of patient companions should regularly review its function by communicating often with the patients and their caregivers. Open communication between patient companions and all those responsible for patient care could improve the present difficulties which exist.     

Lymphoma Secondary to Congenital and Acquired Immunodeficiency Syndromes at a Turkish Pediatric Oncology Center

The prevalence of lymphoma in primary immunodeficiency cases and autoimmune diseases, as well as on a background of immunodeficiency following organ transplants, is increasing. The lymphoma treatment success rate is known to be a low prognosis. Our study aimed to emphasize the low survival rates in immunodeficient vs. immunocompetent lymphoma patients and also to investigate the effect of rituximab in patients with ataxia telangiectasia and other immunodeficiencies. We summarized the clinical characteristics and treatment results of 17 cases with primary immunodeficiency that developed non-Hodgkin lymphoma (NHL) and Hodgkin lymphoma (HL) retrospectively. Seven patients were diagnosed with ataxia-telangiectasia, two with common variable immunodeficiency, two with selective IgA deficiency, one with X-related lymphoproliferative syndrome, one with Wiskott-Aldrich syndrome, one with Epstein-Barr virus-related lymphoproliferative syndrome, one with interleukin-2-inducible T-cell kinase (ITK) deficiency, and one with lymphoma developing after autoimmune lymphoproliferative syndrome (ALPS). One patient underwent a renal transplant. Of the nine males and eight females (aged 3–12 years, median?=?7) that developed lymphoma, seven were diagnosed with HL and ten with NHL (seven B-cell, three T-cell). The NHL patients were started on the Berlin-Frankfurt-Münster, POG9317, LMB-96, or R-CHOP treatment protocols with reduced chemotherapy dosages. HL cases were started on the doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) and/or cyclophosphamide, vincristine, procarbazine, and prednisone (COPP) protocol, also with modified dosages. Importantly, all seven cases of HL are alive and in remission, while six of the ten NHL patients have died. Primary immunodeficiency is a strong predisposing factor for developing lymphoma. Low treatment success rates relative to other lymphomas and difficulties encountered during treatment indicate that new treatment agents are needed. While some success has been achieved by combining rituximab with lymphoma treatment protocols in B-NHL cases with primary immunodeficiency, the need for new treatment approaches for these patients remains critical.     

The macular findings on spectral-domain optical coherence tomography in premature infants with or without retinopathy of prematurity

The purpose of the study was to present spectral-domain optical coherence tomography (OCT) findings in premature infants with or without mild-to-severe retinopathy of prematurity (ROP). Seventy-two infants born <37 weeks of gestation were analyzed, prospectively. Group 1 (n = 18) included infants without ROP. Infants with stage 1, 2, or 3 ROP without indication for treatment formed the second group (n = 15). Group 3 (n = 21) included threshold cases, who would receive laser photocoagulation (LPC) after OCT examinations. Group 4 (n = 18) had already received LPC. The mean central foveal thickness (CFT) (μm) in right eyes was 194.27 ± 19.93, 207.67 ± 25.44, 224.29 ± 21.42, and 222.00 ± 37.80, for groups 1, 2, 3, and 4, respectively (p = 0.01). The presence of a well-formed foveal pit was documented in 60 % of right and 67 % of left eyes in group 1, while a well-formed foveal pit was observed in 14 % of right and 16 % of left eyes in group 3 (p < 0.05). Cystoid macular edema (CME) was shown in 29 % of right and 21 % of left eyes in group 3 (p < 0.05 for right eyes). CME was observed in two of right and left eyes in group 4. Epiretinal membrane (ERM) was shown in one right eye in group 3, two right and four left eyes in group 4 (p < 0.05 for left eyes). Thicker CFT, CME, and failure of a well-formed foveal pit could be related to the severity of ROP. The development of ERM could be the consequence of LPC.     

Wound healing potential of Sambucus ebulus L. leaves and isolation of an active component,quercetin 3-O-glucoside

Ethnopharmacological relevance

The leaves of Sambucus ebulus L. are used in Turkish folk medicine for treatment of high fever, rheumatic pains, snake bites and wounds.

Aim of the study

Four different solvent extracts by using n-hexane, diethyl ether, ethyl acetate and methanol were prepared from the leaves of Sambucus ebulus in order to investigate the claimed wound healing activity in vivo and isolation of active component(s) from the active extract through the bioassay-guided fractionation procedures.

Materials and methods

Linear incision and circular excision wound models on rats and mice were employed. The methanol extract was fractionated by successive chromatographic techniques. Wound healing activity of each fraction was investigated following the bioassay-guided fractionation procedures. Moreover, the tissue samples were examined histopathologically.

Results

Significant wound healing activity was observed for the ointment prepared with methanol extract at 1% concentration. The methanol extract treated groups of animals showed 84.3% contraction in circular excision model, which was close to contraction value of the reference drug Madecassol^® (100%). On the other hand, a significant increase (43.7%) in the wound tensile strength was determined with the same extract on incision wound model. Subfractions showed significant but reduced wound healing activity on both in vivo wound models. A flavonoid derivative “quercetin 3-O-glucoside” was isolated and determined as one of the active component of active final subfraction. The results of histopathological examination supported the outcome of linear incision and circular excision wound models.

Conclusion

The experimental data revealed that the methanolic extract of Sambucus ebulus leaves displayed remarkable wound healing activity.
