Objective: To investigate the symptoms of lung cancer in Turkey and to evaluate approaches to alleviate these symptoms. Subjects and Methods: This study included 1,245 lung cancer patients from 26 centers in Turkey. Demographic characteristics as well as information regarding the disease and treatments were obtained from medical records and patient interviews. Symptoms were evaluated using the Edmonton Symptom Assessment Scale (ESAS) and were graded on a scale between 0 and 10 points. Data were compared using the χ², Student t, and Mann-Whitney U tests. Potential predictors of symptoms were analyzed using logistic regression analysis. Results: The most common symptom was tiredness (n = 1,002; 82.1%), followed by dyspnea (n = 845; 69.3%), appetite loss (n = 801; 65.7%), pain (n = 798; 65.4%), drowsiness (n = 742; 60.8%), anxiety (n = 704; 57.7%), depression (n = 623; 51.1%), and nausea (n = 557; 45.5%). Of the 1,245 patients, 590 (48.4%) had difficulty in initiating or maintaining sleep. The symptoms were more severe in stages III and IV. Logistic regression analysis indicated a clear association between demographic characteristics and symptom distress, as well as between symptom distress (except nausea) and well-being. Overall, 804 (65.4%) patients used analgesics, 630 (51.5%) received treatment for dyspnea, 242 (19.8%) used enteral/parenteral nutrition, 132 (10.8%) used appetite stimulants, and 129 (10.6%) used anxiolytics/antidepressants. Of the 799 patients who received analgesics, 173 (21.7%) reported that their symptoms were under control, and also those on other various treatment modalities (dyspnea: 78/627 [12.4%], appetite stimulant: 25/132 [18.9%], and anxiolytics/antidepressants: 25/129 [19.4%]) reported that their symptoms were controlled. Conclusion: In this study, the symptoms progressed and became more severe in the advanced stages of lung cancer, and palliative treatment was insufficient in most of the patients in Turkey.

Data from this study indicate that oral vit-B12 (1000 μg) for 4 months is effective, giving clinicians more choice, for treatment of children with nutritional vit-B12 deficiency. However, despite this high dose, lower levels were achieved in older children indicating the necessity of dosage adjustment in accordance with body weight.

Crimean-Congo hemorrhagic fever (CCHF) is an acute tick-borne disease caused by Nairovirus, and it is sometimes characterized by reactive hemophagocytic histiocytosis (HLH). The reasons for reactive HLH are macrophage-activating syndrome and disseminated intravascular coagulation due to cytokine storm, liver dysfunction, and endothelial damage by the virus. In this study, the effectiveness of high-dose methylprednisolone (HDMP) (5 to 30 mg/kg/d), fresh frozen plasma (FFP), and intravenous immunoglobulin (IVIG) was investigated in patients with CCHF associated with reactive HLH. Twelve patients with CCHF in association with reactive HLH were included in the study. The patients were successfully treated with HDMP to suppress the macrophage activation, FFP to treat disseminated intravascular coagulation, and IVIG to treat severe thrombocytopenia. No patients received ribavirin. Fever reduced in 1.6 ± 0.8 days, WBC count increased above 4.500/µL in 4.0 ± 2.4 days, platelet count increased above 150.000/µL in 8.5 ± 2.5 days, and D-dimer level decreased under 1 mcg/dL in 5.8 ± 3.6 days. Consequently, HDMP, FFP, and IVIG may be effective in patients with CCHF associated with reactive HLH during hemorrhagic period of the disease.

Particular fibrinogen g chain mutations occurring in the g-module induce changes that hamper g-g dimerization and provoke intracellular aggregation of the mutant fibrinogen, defective export and plasma deficiency. The hepatic storage predisposes to the development of liver disease. This condition has been termed hereditary hypofibrinogenemia with hepatic storage (HHHS). So far, seven of such mutations in the fibrinogen g chain have been detected. We are reporting on an additional mutation occurring in a 3.5-year-old Turkish child undergoing a needle liver biopsy because of the concomitance of transaminase elevation of unknown origin and low plasma fibrinogen level. The liver biopsy showed an intra-hepatocytic storage of fibrinogen. The molecular analysis of the three fibrinogen genes revealed a mutation (Fibrinogen Trabzon Thr371Ile) at exon 9 of the g chain in the child and his father, while the mother and the brother were normal. Fibrinogen Trabzon represents a new fibrinogen g chain mutation fulfilling the criteria for HHHS. Its occurrence in a Turkish child confirms that HHHS can present in early childhood and provides relevant epidemiological information on the worldwide distribution of the fibrinogen g chain mutations causing this disease. By analyzing fibrinogen crystal structures and calculating the folding free energy change (DDG) to infer how the variants can affect the conformation and function, we propose a mechanism for the intracellular aggregation of Fibrinogen Trabzon and other g-module mutations causing HHHS.
