Periodontopathogen profile of healthy and oral lichen planus patients with gingivitis or periodontitis

Oral lichen planus （OLP） is a chronic inflammatory disease that is frequently detected in oral tissues. The aim of our study was to identify the prevalence of the detection of periodontopathogenic microorganisms （Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Prevotella intermedia, Tannerella forsythia and Treponema denticola in OLP patients and to compare with this prevalence of periodontopathogenic microorganisms in healthy non-OLP patients. Our study included 27 （18 chronic periodontitis （OLPP） and 9 gingivitis （OLPG）） patients diagnosed with OLP along with 26 （13 chronic periodontitis （HP） and 13 gingivitis （HG）） healthy non-OLP patients. The multiplex polymerase chain reaction （PCR）with subsequent reverse hybridization method （micro-IDent） was used for identifying periodontopathogenic microorganisms present in subgingival plaque samples. The percentages of detection for A. actinomycetemcomitans, P. gingivalis, P. intermedia, T. forsythia and T. denticola in subgingival plaque samples taken from OLP patients （OLPG and OLPP） were 18.5%, 85.1%, 81.4%, 88.8% and 74%, respectively. Meanwhile, in the non-OLP patients （HG and HP）, these values were 7.6%, 50%, 46.1%, 73% and 57.7%, respectively. Thus, comparing the non-OLP groups with the OLP groups, the periodontopathogens＇ percentages of detection in the OLP groups were higher than those in the non-OLP groups. According to our study results, OLP patients have higher levels of infection with A. actinomycetemcomitans, P. gingivalis, P. intermedia, T. forsythia and T. denticola than non-OLP patients. We argue that the high percentages in patients with OLP may help identify the importance of periodontopathoRenic microorganisms in the progress of periodontal diseases of OLP.

Pulmonary arterial dissection in a post-partum patient with patent ductus arteriosus: Case report and review of the literature

Pulmonary arterial dissection is an uncommon but usually a deadly complication of chronic pulmonary hypertension. A 26-year-old female patient was admitted to our clinics with sudden dyspnea and chest discomfort one hour after giving birth to twins by vaginal delivery. An echocardiography was performed with a pre-diagnosis of pulmonary embolism. However, echocardiographic examination revealed a dilated main pulmonary artery and a dissection flap extending from main pulmonary artery to left pulmonary artery. In summary, in this report, we described a very rare case of pulmonary artery dissection in a pregnant patient with a previously un-diagnosed patent ductus arteriosus without an obvious rise in pulmonary artery pressure and reviewed the relevant literature.

Relationship between non-alcoholic fatty liver disease and coronary heart disease

Non-alcoholic fatty liver disease(NAFLD)is the leading cause of chronic liver disease and considered a liver manifestation of metabolic syndrome.It is in close relationship with insulin resistance,obesity,diabetes mellitus,all of which increase risk of cardiovascular disease(CVD).Besides,many studies point out that NAFLD independently contributes to the development of atherosclerosis and CHD.On the other hand,CVDs are the leading cause of death in NAFLD patients.Many pathophysiological changes and molecular mechanisms play an important role in NAFLD for CVD formation.Atherosclerosis is common in NAFLD,which also mainly contributes to the CVD formation and CHD.Many studies linking atherosclerotic CHD and NAFLD are present in the literature.Subclinical CHD,mainly detected by coronary computed tomography views,have been detected more common in NAFLD patients.Presence of NAFLD has been found to be more common in patients with severe CHD and in stable CHD,NAFLD has been found to be associated with more diffuse disease.In acute coronary syndromes,especially in acute myocardial infarction,patients with NAFLD have been found to have poor prognosis when compared with NAFLD free patients.In this review,our aim is to evaluate the relationship between NAFLD and CHD in detail and go over the pathophysiological mechanisms underlying this relationship.

A 99-year old patient with takotsubo cardiomyopathy recovering from cardiogenic shock

Takotsubo syndrome(TTS)is a rare clinical entity commonly seen in post-menopausal women after an emotional or sometimes physical stress.[1,2]This syndrome is thought to be caused by increased circulation catecholamine levels secondary to an adrenergic stimulus resulting in transient coronary spasm and microvascular dysfunction.[3]TTS is characterized by acute and reversible left ventricular dysfunction with the typical ECG and clinical findings of an acute coronary syndrome but no significant coronary stenosis.[4]Typically,in TTS,antero-apical ballooning is observed in ventriculography,and segmentary wall motion abnormalities are observed in magnetic resonance imaging and echocardiography.Acute heart failure,left ventricular outflow tract obstruction,mitral regurgitation and cardiogenic shock may complicate this syndrome.[5]Herein,we present a case who is the oldest one in the literature with TTS and cardiogenic shock.
