ABSTRACT
Background: Checkpoint inhibitors (CPIs) have improved survival compared to chemotherapy alone in advanced nonsmall-cell lung cancer (NSCLC). This article aims to compare indirect evidence and rank the effect of different CPIs in this setting. Materials and Methods: In this network meta-analysis, we searched for trials comparing CPIs in advanced NSCLC. Figures for survival endpoints were extracted. In addition, a network meta-regression analysis was carried out. Results: A total of 9220 patients from 16 trials were included in the analysis. In the first-line setting, for the overall survival endpoint, the chemotherapy + Pembrolizumab combination had the highest effectivity rank probability as compared to chemotherapy (hazard ratio = 0.788, 95% credential interval = 0.728–0.855). For the second-line setting, and also for the efficacy in terms of progression-free survival, various CPIs and their combinations were ranked. Conclusion: Some degree of differences in terms of efficacy exists between different types, dosages, settings, and combinations of CPI. We quantify these differences to guide clinical practice
ABSTRACT
ABSTRACT Background: Our study investigates whether Native Thiol, Total Thiol and disulphide levels measured in serum of patients with prostate cancer and prostatitis and of healthy subjects, have any role in differential diagnosis. Materials and Methods: Patients followed up for histopathologically verified diagnosis of prostate cancer and prostatitis in 2016-2017 at the Medicalpark Gaziantep Hospital Urology Clinic were included in the study. Native Thiol (NT), Total Thiol (TT), Dynamic Disulphide (DD) levels in serum were measured by a novel automated method. Results: NT, TT, DD, NT / TT ratios, DD / TT ratio and DD / NT ratio were measured as 118.4 ± 36.8μmoL / L, 150.3 ± 45.3μmoL / L, 15.9 ± 7μmoL / L, 78.8 ± 7μmoL / L, 10.5 ± 3.5μmoL / L, 13.8 ± 5.8μmoL / L respectively in patients with prostate cancer; as 116.4 ± 40.5μmoL / L, 147.5 ± 50.1μmoL / L, 15.5 ± 8.7μmoL / L, 79.7 ± 9μmoL / L, 10.1 ± 4.5μmoL / L, 13.5 ± 7.2μmoL / L in patients with prostatitis and as 144.1 ± 21.2μmoL / L, 191 ± 32.3μmoL / L, 23.4 ± 10.1μmoL / L, 76.1 ± 98.3μmoL / L, 11.9 ± 4.1μmoL / L, 16.4 ± 6.9μmoL / L in healthy subjects. Significant difference was detected between groups of NT, TT and DD levels (p = 0.008, p = 0.001, p = 0.002). No significant difference was detected in terms of the NT / TT, DD / TT and DD / NT rates (p = 0.222, p = 0.222, p = 0.222). Conclusions: Serum NT, TT, DD levels in patients with prostatitis and prostate cancer were found significantly lower compared to the control group. This indicates that just as inflammation, prostate cancer also increases oxidative stress on tissues.

BACKGROUND AND OBJECTIVES: In this study, the aim was to compare postoperative analgesia effects of the administration of ultrasound-guided interscalene brachial plexus block and intra-articular bupivacaine carried out with bupivacaine. METHODS: In the first group of patients 20 mL 0.25% bupivacaine and ultrasound-guided interscalene brachial plexus block (ISPB) were applied, while 20 mL 0.25% bupivacaine was given via intra-articular (IA) administration to the second group patients after surgery. Patients in the third group were considered the control group and no block was performed. Patient-controlled analgesia (PCA) with morphine was used in all three groups for postoperative analgesia. RESULTS: In the ISPB group, morphine consumption in the periods between 0-4, 6-12 and 12-24 postoperative hours and total consumption within 24 h was lower than in the other two groups. Morphine consumption in the IA group was lower than in the control group in the period from 0 to 6 h and the same was true for total morphine consumption in 24 h. Postoperative VASr scores in the ISPB group were lower than both of the other groups in the first 2 h and lower than the control group in the 4th and 6th hours (p < 0.05). In the IA group, VASr and VASm scores in the 2nd, 4th and 6th hours were lower than in the control group (p < 0.05). CONCLUSION: Interscalene brachial plexus block was found to be more effective than intra-articular local anesthetic injection for postoperative analgesia. .
JUSTIFICATIVA E OBJETIVOS: Comparar os efeitos na analgesia no pós-operatório da administração de bloqueio do plexo braquial por via interescalênica guiado por ultrassom e bupivacaína intra-articular, feito com bupivacaína. MÉTODOS: No primeiro grupo de pacientes, 20 mL de bupivacaína a 0,25% e bloqueio do plexo braquial por via interescalênica guiado por ultrassom (BPBI) foram administrados, enquanto 20 mL de bupivacaína a 0,25% foram administrados por via intra-articular (IA) ao segundo grupo de pacientes após a cirurgia. Os pacientes do terceiro grupo foram considerados grupo controle e nenhum bloqueio foi feito. Analgesia controlada pelo paciente (ACP) com morfina foi usada nos três grupos para analgesia pós-operatória. RESULTADOS: No grupo BPBI, o consumo de morfina nos períodos entre 0-4, 6-12 e 12-24 horas após a cirurgia e o consumo total em 24 horas foram mais baixos do que nos outros dois grupos. O consumo de morfina no grupo IA foi menor do que no grupo controle no período de 0-6 horas, como também foi menor o consumo total de morfina em 24 horas. Os escores EVAr no pós-operatório do grupo BPBI foram menores do que os escores dos dois outros grupos nas primeiras duas horas e menores do que os do grupo controle nos períodos de 4 e 6 horas (p < 0,05). No grupo IA, os escores EVAr e EVAm nos períodos de 2, 4 e 6 horas foram menores do que no grupo controle (p < 0,05). CONCLUSÃO: O bloqueio do plexo braquial por via interescalênica mostrou ser mais eficaz do que a injeção intra-articular de anestésico local para analgesia pós-operatória. .

A 35-year-old woman presented with a thyroid mass, weakness and shortness of breath of 3 years duration. On physical examination, she had a diffusely enlarged thyroid gland with multiple nodules. There were no signs to suggest immune suppression. The patient farmed and raised livestock. Biochemical tests and hemogram were normal. She underwent surgery, and a histological examination of the surgical specimen revealed nodular hyperplasia. Microscopically, silver methenamine (PASM) stain-positive hyphae that divided into branches at 45° and conidia were detected beside the thyroid capsule, with conidia in the cystic nodule. Moreover, ischemic changes of the thyroid tissue were observed closer to the capsule. We report a case of Aspergillosis of the thyroid of a patient who underwent surgery for a multinodular goiter.
ABSTRACT
Scintigraphy with technetium-99m methylene diphosphonate (MDP) was performed in a 76-year-old male with prostatic cancer. Tc-99m MDP bone scintigraphy showed a linear markedly increased accumulation of radioactivity in both femoral arteries. Radiopharmaceutical uptake in femoral arteries was confirmed with a colour Doppler ultrasonography as femoral artery calcification. This increased uptake of Tc-99m MDP in the patient is strongly related to the calcium deposition. Tc-99m MDP scintigraphy depicts a wide spectrum of nonosseous disorders. Abnormal soft tissue uptake of Tc-99m MDP demostrates hormonal, neoplastic, inflammatory, ischemic, traumatic, excretory and artifactural entities. Hormonal disturbances in calcium metabolism, particularly in hyperparathyroidism, can lead to metastatic calcification and can be visualized with Tc-99m MDP scintigraphy. Mechanisms leading to increased extraosseous Tc-99m MDP uptake include extracellular fluid expansion, enhanced regional vascularity and permeability, and the presence of other metallic ions (eg, iron and magnesium) are also important
