Objective: Premature ventricular contractions (PVCs) are a common arrhythmic condition. The first approach in patients with symptomatic and frequent PVC is medical treatment, primarily beta-blockers (BB) or calcium channel blockers (CCB), but it is still unclear which of the two should be chosen. This study investigated which drug treatment would be beneficial according to patient and electrocardiography (ECG) characteristics in patients with idiopathic PVC. Methods: We retrospectively analyzed 156 patients with PVC who came to the cardiology outpatient clinic. Seventy-one patients were responsive to BB, and 85 were responsive to CCB. Their demographic and ECG characteristics were compared. Results: The male ratio was higher (p<0.001), and the left ventricular ejection fraction was lower in BB responders than in CCB responders (p<0.001). Although the mean heart rate was higher in BB responders (p<0.001), the initial PVC burden was lower in BB responders than in CCB responders (p<0.001). The PVC QRS duration was longer in BB responders than in CCB responders (p<0.001). Similarly, the coupling interval variability was higher in BB responders (p=0.006). Conclusions: The evaluation of clinical and ECG parameters in patients with frequent idiopathic PVCs may determine whether BBs or CCBs should be chosen as initial treatment. Further prospective studies are needed to verify our findings and establish their clinical applicability. [ABSTRACT FROM AUTHOR]

Purpose: The aim of this study is to provide data about diagnosis, treatment, and results of the patients poisoned by drugs affecting the cardiovascular system. Materials and Methods: Patients aged 18 and over who applied to the emergency department with drug poisoning affecting cardiovasculer system were included in the study. The demographic data, drugs and doses, emergency treatment and the time of development of shock or bradycardia, treatment, antidotes and invasive procedures were recorded. Results: In our study twenty-five patients, 8 (32 %) male and 17 (68 %) female, were included. At the admission, 56 % (n=14) had hypotension, 8 % (n=2) had bradycardia, at the second hour 76 % (n=19) had hypotension, 16 % (n=4) had bradycardia. Within 6 hours after admission, 80 % (n=20) patients had hypotension, 28 % (n=7) patients had bradycardia at least once. Fifty-two percent (n=13) of the patients calcium, 36 % (n=9) glukagon, 32 % (n=8) lipid, 12 % (n=3) atropine, 20 % (n=5) positive inotropes were given. Conclusion: Lipid therapy produces positive results in patients who did not improve with calcium, glucagon and fluid therapy. Patients who received calcium channel blockers experienced more cardiogenic shock and bradycardia was more common in patients receiving beta-blockers.

Objective: A study was planned to investigate the effect of exposure to cigarette smoke and the effects of calcium channel blockers in experimentally induced sciatic nerve injuries. Material-Method: The sciatic nerve was cut on one side in all the groups, and repair was performed in hour 0. After repair, a single daily dose of 1 ml of 0.9% saline was administered to group 1, 90 days, 30 minutes, cigarette smoke to group 2, 1mg/kg calcium channel blocker to group 3, 90 days, 30 minutes, cigarette smoke and 1mg/kg Calcium channel blocker was given to group 4. Results: At the end of the 12th week, gait analysis at and sciatic function index (SFI), the number of myelinated axons, axon areas and myelin diameters were assessed. There was a significant difference between the measured values of SFI in group 1 and group 3 and 4, and there was a significant difference between group 2 and group 3 and 4 (p

Combination antihypertensive treatments are usually used in everyday life, which has a life-threatening risk of using an overdose accidentally or suicidally. The effects of calcium channel blockers on the cardiovascular system are negative chronotropic, myocardial depression, decreasing atrioventricular signals, and vasodilatation. Beta blocker drugs are affected to beta receptors of catecholamines with competitively inhibition. Hypotension and bradycardia are the most common cardiac manifestations, and the others are arrhythmias, pulmonary edema, depression of the central nervous system. A previously healthy 4-year-old boy used accidentally 240 mg verapamil/4 mg trandolapril two pieces and 5 mg nebivolol one, at the time of admission his clinical condition was in cardiogenic shock. We successfully treated him with insulin-euglycemia/glucagon treatment, calcium, and lipid infusion therapy, plasmapheresis, and continuous venovenous hemodiafiltration without any sequels. The intoxication of calcium channel blockers and beta blocker drugs are rare but severe cases because of life-threatening. [ABSTRACT FROM AUTHOR]

Objective: Repurposing non-cancer drugs for cancer treatment has many advantages. We can access to a new cancer drug easily, quickly and cheaply. In addition, we generally know safety prifile of repurped drugs. There are few studies in the literature investige the anticancer effects of Calcium channel blockers (CCBs). We planned to investigate the anticancer effects of CCBs on colon cancer cell line. Material and Method: We adminestered different doses of T-type CCB NNC-55-0396 and L-type CCB amlodipine on colon cancer cell line HT-29. MTT analysis was performed at 48 hours to measure cell viability. The doseresponse curve was constructed using GraphPad Prism.8 programme. Results: Amlodipine caused more than 90% cytotoxicity at all concentrations of 500, 250, 100, 50, 10 µg/ml in MTT analysis at 48 hours. Similarly, NNC-55-0396 caused more than 90% cytotoxicity at all 80, 40, 20, 10.5 µM concentrations. Discussion: In our study, NNC-55-0396 and amlodipine molecules showed severe cytotoxicity on HT-29 cells. There are publications indicating that it may have other anticancer effects other than cytotoxicity. They are promising molecules as anti-cancer drugs. They should be investigated in clinical studies alone or in combination with other cancer drugs. [ABSTRACT FROM AUTHOR]

Dişeti büyümesi düzenli diş pratiğinde rutin bir bulgudur. Pek çok etiyolojik etkene sahip olmasına rağmen, sistemik problemleri tedavi etmek için uygulanan ilaçlara bağlı genişleme, dikkat edilmesi gereken önemli bir konudur. İlaç kaynaklı dişeti aşırı büyümesi sıklıkla anti hipertansifler, antikonvülzanlar ve immünsüpresanlar ile ilişkilidir. Gingival büyüme geliştikçe, normal ağız hijyeni pratiğini etkiler ve çiğneme fonksiyonlarına müdahale edebilir. Bu yavaş yavaş bir ağrı kaynağı haline gelir ve durum genellikle bozulmaya yol açar. Bu istenmeyen etkiyi geliştiren hasta grubunda, dişeti değişimlerinin boyut ve şiddetinde değişkenlik olduğu görülmektedir. Olası risk faktörlerini tanımlamak ve araştırmak ve tedavi planı ile ilişkilendirmek ideal görünmektedir. Burada, beş yıldan beri nifedipin tedavsi almaktayken ilaca bağlı gingival büyümesi olan 33 yaşında bir kadın hasta sunulmuş ve tedavisi tartışılmıştır.

Gingival enlargement is a routine finding in regular dental practice. Though it has many etiological factors, enlargement due to drugs which are administered to treat the systemic problems is of major concern which needs attention. Drug-induced gingival overgrowth is frequently associated with anti hypertensives, anticonvulsants and immunosuppressants. As gingival enlargement develops, it affects the normal oral hygiene practice and may interfere with masticatory functions. It gradually becomes a source of pain and the condition often leads to disfiguration. Within the group of patients that develop this unwanted effect, there appears to be variability in the extent and severity of the gingival changes. It would seem ideal to identify and explore possible risk factors and relate them with the treatment plan. Here, we present a case of a 33 year old female patient on nifedipine since five years with drug induced gingival enlargement and its management. [ABSTRACT FROM AUTHOR]

Aim: Calcium channel blockers (CCB) and beta blockers (BB) are primarily used to treat hypertension. Overdose of these medications can occur by accidental ingestion or ingestion for suicide attempt. Morbidity and mortality are higher in these poisonings compared to other poisonings. In this study, BB or CCB drug poisoning cases are discussed and the literature is reviewed. Material and Method: Between January 2011 and July 2012, 590 cases of drug poisoning were admitted in the Pediatric Intensive Care Unit. In this study, 16 of these 590 subjects who were poisoned with calcium channel blockers or beta blockers were evaluated. 11 (68.8%) patients were female and 5 (31.2%) were male. Mean age of the patients was 11.8±5.94 (2.5-18) years. Results: Hypotension was the most common clinical sign in CCB poisoning. Two patients were asymptomatic. On ECG, QT prolongation was found in four patients, AV block was found in two patients and ST depression was found in one patient. Nausea, vomiting, hypotension, lethargy and tremor were the most common clinical findings in patients with BB intoxication. Although seven patients had normal ECG, one patient had QT prolongation and one patient had Wolff-Parkinson-White syndrome. Only dopamine was given to two patients with CCB poisoning, dopamine and dobutamine were given to one patient and dopamine, dobutamine, epinephrine, norepinephrine, glucagon and insulin were given to another patient. Inotropic drugs were not given to any patient with BB poisoning. IV Ca-gluconate was given to all patients with CCB poisoning except two patients who were asymptomatic. 15 patients were discharged, while one patient with CCB poisoning was lost. Conclusions: Because the prognosis of CCB or BB poisoning may be very severe, these patients should be followed up in a fully-equipped pediatric intensive care unit. [ABSTRACT FROM AUTHOR]

Amaç: Kalsiyum kanal ve anjiotensin 2 reseptör blokerleri ile olan zehirlenmelerde hayatı tehdit edici kardiyovasküler kollaps bulguları gelişebilmekte ve tedavi için özgül bir antidot bulunmamaktadır. Biz de bu olgu ile hayati tehlike yaratabilen bu zehirlenmelere tekrar dikkat çekmek ve destek tedaviye yanıtsız olgularda intravenöz lipit infüzyonu tedavisinin başarılı olabileceğini vurgulamak istedik. Olgu: On dokuz yaşında bayan olgu, aşırı doz olmesartan ve amlodipin alımını takiben ciddi hipotansiyon ve bradikardi bulguları ile getirildi. Kardiyovasküler kollaps tablosu sıvı tedavisi, kalsiyum glukonat ve yüksek doz vasopressör infüzyonuna dirençli idi. Hiperinsülinemik öglisemi tedavisi ile de dirençli hipotansiyonu devam eden olguya intravenöz lipit infüzyonu izleminin 1. saatinde uygulandı. Olgunun yüksek doz vasopressör ihtiyacı devam etmesi üzerine intravenöz glukagon verildi. Lipit ve glukagon tedavisine yanıt alınan olgunun intravenöz noradrenalin dozları azaltıldı. Olgu izlemin 9. günü extübe edilerek 12. Günü yoğun bakımdan servise nakledildi. 14. günde şifa ile taburcu edildi. Sonuç: Kalsiyum kanal ve anjiotensin II reseptör blokerleri ile olan zehirlenmeler, hayatı tehdit edebilen zehirlenmelerdir. Bu zehirlenmelerde önerilen klasik destek tedavileri yetersiz kalabilmekte, intravenöz lipit infüzyonu ile başarılı sonuçlar alınabilmektedir. [ABSTRACT FROM AUTHOR]
