Turkish Journal of Medical Sciences

Infectious diseases remain as the significant causes of human and animal morbidity and mortality, leading to extensive outbreaks and epidemics. Acute respiratory viral diseases claim over 4 million deaths and cause millions of hospitalizations in developing countries every year. Emerging viruses, especially the RNA viruses, are more pathogenic since most people have no herd immunity. The RNA viruses can adapt to the rapidly changing global and local environment due to the high error rate of their polymerases that replicate their genomes. Currently, coronavirus disease 2019 (COVID-19) is determined as an infectious disease caused by severe acute respiratory syndrome coronavirus 2 …

Covid-19, Immune System Response, Hyperinflammation And Repurposingantirheumatic Drugs, Abdurrahman Tufan, Aslihan Avanoğlu Güler, Marco Matucci-Cerinic

Turkish Journal of Medical Sciences

In the Wuhan Province of China, in December 2019, the novel coronavirus 2019 (COVID-19) has caused a severe involvement of the lower respiratory tract leading to an acute respiratory syndrome. Subsequently, coronavirus 2 (SARS-CoV-2) provoked a pandemic which is considered a life-threatening disease. The SARS-CoV-2, a family member of betacoronaviruses, possesses singlestranded positive-sense RNA with typical structural proteins, involving the envelope, membrane, nucleocapsid and spike proteins that are responsible for the viral infectivity, and nonstructural proteins. The effectual host immune response including innate and adaptive immunity against SARS-Cov-2 seems crucial to control and resolve the viral infection. However, the severity …

Behçet Syndrome As A Construct, Hasan Yazici Jan 2020

Behçet Syndrome As A Construct, Hasan Yazici

Turkish Journal of Medical Sciences

We still do not know the cause(s) of Behçet syndrome. Most probably several, separate disease mechanisms are involved. I, like some others, propose we call it not a disease but a syndrome, a construct with a list of strong and weak elements. I like to think that this frank admission of our ignorance of its cause(s) will be an important semantic stimulus for more meaningful research.

Turkish Journal of Medical Sciences

Behçet's disease (BD) is a systemic and inflammatory disorder that is mainly present along the ancient Silk Road, from the Mediterranean Sea to East Asia. A wide range of prevalence figures (0.1-420/100,000) have been reported for BD, also among Turkish populations of similar genetic background living in different countries. Recently, a decline in the incidence of BD and a change of the disease spectrum to less-severe manifestations have been reported from Japan and Korea, two genetically homogenous, affluent populations with limited immigration. It was hypothesized that a decline in infectious diseases, especially dental/periodontal infections, associated with the improvement in oral …

Familial Mediterranean Fever, From Pathogenesis To Treatment: A Contemporary Review, Abdurrahman Tufan, Helen Lachmann

Turkish Journal of Medical Sciences

Familial Mediterranean fever (FMF) (OMIM #249100) is the most common hereditary autoinflammatory disease in the world. FMF is caused by gain of function mutations of MEFV gene which encodes an immune regulatory protein, pyrin. Over the last few years, we have witnessed several new developments in the pathogenesis, genetic testing, diagnosis, comorbidities, disease related damage and treatment approaches to FMF. Elucidation of some of the pathogenic mechanisms has led to the discovery of pathways involved in inflammatory, metabolic, cardiovascular and degenerative diseases. The use of next generation sequencing in FMF has revealed many new gene variants whose clinical significance may …

Update On Liver Transplantation-Newer Aspects, Rahşan Olga Meti̇n, Cem Şi̇mşek, Ahmet Ömür Gürakar

Turkish Journal of Medical Sciences

Liver transplantation (LT) remains the only therapeutic option offering gold standard treatment for end-stage liver disease (ESLD) and acute liver failure (ALF), as well as for certain early-stage liver tumors. Currently, the greatest challenge facing LT is the simple fact that there are not enough adequate livers for all the potential patients that could benefit from LT. Despite efforts to expand the donor pool to include living and deceased donors, organ shortage is still a major problem in many countries. To solve this problem, the use of marginal liver grafts has become an inevitable choice. Although the definition of marginal …


Thalamocortical Network Interruption: A Fresh View For Migraine Symptoms, Hayrunni̇sa Bolay Belen Jan 2020

Thalamocortical Network Interruption: A Fresh View For Migraine Symptoms, Hayrunni̇sa Bolay Belen

Turkish Journal of Medical Sciences

Migraine is a multifaceted brain disorder where multisensory disturbances are associated with headache. Yet sensory symptoms are conventionally justified by dysfunctions confined to the cerebral cortex, a perspective through the complex interplay of thalamocortical network would provide the entire picture, more pertinent to the central sensory processing. It is important to consider thalamus as a hub that integrates multiple domains via extensive connections among anatomically and functionally separate cortical areas. Accordingly, cortical spreading depression (CSD), implicated in migraine pathophysiology can be seen as a tool to disconnect thalamocortical network by functionally eliminating cerebral cortex. Hence, including thalamic reticular nucleus and …


Tuberous Sclerosis: A Review Of The Past, Present, And Future, Sanem Pinar Uysal, Mustafa Şahi̇n Jan 2020

Tuberous Sclerosis: A Review Of The Past, Present, And Future, Sanem Pinar Uysal, Mustafa Şahi̇n

Turkish Journal of Medical Sciences

Tuberous sclerosis complex (TSC) is an autosomal dominant, multisystem disorder that is characterized by cellular and tissue dysplasia in several organs. With the advent of genetic and molecular techniques, mutations in the TSC1 or TSC2 genes were discovered to be responsible for mTOR overactivation, which is the underlying mechanism of pathogenesis. TSC is a highly heterogenous clinical entity with variable presentations and severity of disease. The brain, heart, skin, eyes, kidneys, and lungs are commonly involved in this syndrome, with neurologic symptoms comprising a significant source of morbidity and mortality. In 2012, the diagnostic criteria for TSC were revised by …


Molecular Subtyping Bladder Cancer: Is It Ready For Clinical Practice?, Funda Vakar Lopez Jan 2020

Molecular Subtyping Bladder Cancer: Is It Ready For Clinical Practice?, Funda Vakar Lopez

Turkish Journal of Medical Sciences

Bladder cancer, one of the more common cancers, is a heterogeneous disease, both morphologically and clinically. Although histological classification and extent of the disease (staging) guide treatment options, the heterogeneity in responses to therapy highlights the need for better stratification of patients for the appropriate therapy in order to achieve better outcomes. Several molecular classifications of muscle-invasive bladder cancer have been proposed but currently their use in clinical practice is limited by the complexity of the methods used and diversity of the subtypes.


Immune Gene Therapy Of Cancer, Hakan Akbulut Jan 2020

Immune Gene Therapy Of Cancer, Hakan Akbulut

Turkish Journal of Medical Sciences

Cancer gene therapy emerged as a promising treatment modality 3 decades ago. However, the failure of the first gene therapy trials in cancer treatment has decreased its popularity. Likewise, immunotherapy has followed a similar course. While it was a popular and promising treatment with IL-2 and interferon and cancer vaccines in the 1980s, it later lost its popularity. Immunotherapy became one of the main options for cancer treatment with the successful use of immune checkpoint inhibitors in clinics approximately 10 years ago. The success of immunotherapy has increased even more with the introduction of cancer gene therapy methods in this …
