    Kronik diyarenin nadir bir sebebi: Lenfositik kolit
    (2016) Erkan, Gülbanu; Ramadan, Saime; Saka, Burcu
    Mikroskopik kolit (MK); kronik, kansız, sulu diyareye yol açan bir hastalıktır. Lenfositik kolit (LK) ve kollajenöz kolit (KK) olmak üzere, iki alt tipi bulunmaktadır. Kadınlarda erkeklerden daha sıktır, sıklıkla 5-6. dekadta görülür. Etiyolojisi bilinmemektedir. Çölyak hastalığı, tip 1 diabetes mellitus, otoimmün tiroidit, romatoid artrit gibi otoimmün hastalıklarla beraberliği bildirilmiştir. Tedavide pek çok ilaç, değişik başarı oranları ile kullanılabilir. Kullanılabilen ilaç seçenekleri; kortikosteroidler, antidiyareikler, bizmut, kolestiramin, 5-aminosalisilatlar, immün modülatörler ve anti-TNF ilaçlardır (1).

    Primary gastrointestinal aspergillosis: A case report and literature review
    (EDIMES Edizioni Medico Scientifiche, 2019) Ceylan, Bahadır; Yılmaz, Mesut; Beköz, Hüseyin Saffet; Ramadan, Saime; Ertan Akan, Gülhan; Mert, Ali
    Invasive aspergillosis is a severe infection that generally involves the lungs. Primary gastrointestinal aspergillosis is the least common form of invasive aspergillosis. A patient aged 65 years developed a febrile neutropenic episode following an autologous stem cell transplant for plasmacytoid variant diffuse large B-cell gastric non-Hodgkin’s lymphoma. He had abdominal pain on the second day of the febrile neutropenic episode and ileus occurred on the sixth day. His general condition deteriorated despite broad spectrum antibiotics and caspofungin treatment, and intestinal perforation occurred on the nineteenth day of the febrile neutropenic episode. Pathological examination of the resected jejunum and ileum revealed mould hyphae compatible with aspergillus. The patient died due to massive gastrointestinal bleeding on the fifth post-operative day. Although a rare condition, primary gastrointestinal aspergillosis should be kept in mind while treating neutropenic patients with gastrointestinal symptoms.

    The potential prognostic role of peritumoral eosinophils within whole tumor-associated inflammatory cells and stromal histological characteristics in colorectal cancer
    (Vesalius University Medical Publisher, 2020) Ramadan, Saime; Saka, Burcu; Yarıkkaya, Enver; Bilici, Ahmet; Öncel, Mustafa
    We aimed to determine the prognostic role of whole tumor-associated inflammatory cells, especially eosinophils, and stromal histological characteristics in relation to other prognostic parameters in patients with colorectal carcinoma (CRC). A total of 122 patients who underwent an operation for CRC were included in this retrospective study. Conventional (tumor grade, TNM stage and venous invasion [VI]) and other histopathological (intratumoral/peritumoral budding {ITB/PTB], desmoplasia) tumor parameters were recorded and classified by density, as were the tumor-associated inflammatory parameters (intratumoral/peritumoral lymphocytes {ITL/PTL], eosinophils [IE/PTE], overall inflammation [ITI/PTI], Crohn-like inflammation [CLI]). Cancer-specific survival data were analyzed with respect to all tumor parameters. High ITB and PTB were significantly correlated with a higher rate of pT4, VI and desmoplasia (p < 0.05). An association of moderate ITL and extensive PTL with lesser likelihood of VI and metastasis; an association of extensive CLI with a significantly lower rate of metastasis and TNM stage IV; and minimal PTE with a significantly higher rate of pT4 stage, metastasis and ITB were detected (p < 0.05 for each). Our findings revealed that low score tumoral budding and an increase in tumor-related inflammation were associated with lesser likelihood of poor prognostic tumor parameters. Nonetheless, given the association of an increase in PTE with lesser likelihood of ITB, pT4, metastasis, and with non-significantly for better survival rates, our findings emphasize the potential role of peritumoral eosinophils as an additional prognostic parameter in CRC.
