Radiation therapy is the main treatment for a large number of neoplastic diseases. Improved survival in this group of patients led to the emergence of a new nosological unit – radiation-induced damage to neighbouring organs and systems. Data accumulated in recent decades has proven conclusively that chest radiotherapy could result in heart damage. Cardiovascular diseases are the leading cause of death in oncological patients in remission. The onset of radiation-induced heart disease (RIHD) can be early with clinical picture of acute myocarditis and late with manifestations of constrictive pericarditis, restrictive cardiomyopathy, coronary artery disease, valvular involvement, heart failure and conduction pathology. Clinical symptoms may manifest years after exposure to radiation. Our team performed a mini-review on the topic, after which we shared our own experience in 10 patients who underwent radiation therapy in the past and were admitted to the Clinic of Cardiology of University Multyprofile Hospital for Active Treatment „Deva Mariya“ with a clinical picture of ACS.

Abstract Radiation therapy demonstrates a clear survival benefit in the treatment of several malignancies. However, cancer survivors can develop a wide array of cardiotoxic complications related to radiation. This pathology is often underrecognized by clinicians and there is little known on how to manage this population. Radiation causes fibrosis of all components of the heart and significantly increases the risk of coronary artery disease, cardiomyopathy, valvulopathy, arrhythmias, and pericardial disease. Physicians should treat other cardiovascular risk factors aggressively in this population and guidelines suggest obtaining regular imaging once symptomatology is established. Patients with radiation‐induced cardiovascular disease tend to do worse than their traditional counterparts for the same interventions. However, there is a trend toward fewer complications and lower mortality with catheter‐based rather than surgical approaches, likely because radiation makes these patients poor surgical candidates. When appropriate, these patients should be referred for percutaneous management of valvulopathy and coronary disease.

As advances in medical technology arise and the availability of cancer treatment increases, an increased number of patients are receiving cancer treatment. Radiation therapy has evolved to become one of the cornerstones of treatment for various types of cancers. One of the long-term consequences of radiation therapy is radiation-induced coronary artery disease (RICAD). Although the pathophysiology of RICAD may be slightly different and more acute onset than the commonly seen “generic” coronary artery disease, it is common practice to treat RICAD in the same method as nonradiation-induced CAD. This paper summarizes the current research available on the topic and shows there is not enough research to obtain significant data about outcomes and restenosis rates of PCI or outcomes of CABG in RICAD. The aim of this review is to create a concise and easy-to-follow review of the relevant data regarding RICAD and hopefully spark further interest in future studies in this field.

Over the past 20 years, there has been a trend towards an increase in cancer morbidity in most states, in particular in the US and Russia, for a number of localizations, for example, prostate cancer, uterus, rectum and bladder cancer [6]. These localizations require radiation therapy at least as a part of multi-modal approach, or, quite often, as an independent method of treatment. However, frequency of acute radiation cystitis, according to current publications, after irradiation of the pelvis, remains high 5 to 80% for 100 days)/ Frequency of late radiation complications, which can occur from 3 months after the end of radiation therapy up to 20 years ranges from 5 to 50% [1, 2, 4, 5, 8]. There is a need for randomized, controlled trials to determine standards in the treatment of this formidable complication of radiation therapy. Models of radiation-induced cystitis in animals are being developed to study possible ways of treatmentб but they are either not easy to reproduce, do not imitate treatment regimes in humans to full extent, or cause unnecessary suffering to experimental animals [18]. Authors suggested new model of radiation-induced cystitisclosely resembling regimes used in real patients [7].

This report describes the case of a 61-year-old woman who presented with dyspnea, aortic stenosis, and coronary artery disease—typical side effects of radiation therapy for Hodgkin lymphoma. A poor candidate for surgery, she underwent successful high-risk percutaneous coronary intervention and subsequent transcatheter aortic valve replacement. This report highlights some of the cardiovascular-specific sequelae of radiation therapy for cancer treatment; in addition, possible directions for future investigations are discussed.

Background: Myocardial bridging of the left anterior descending (LAD) artery may result in clinical symptoms. Surgery with cardiopulmonary bypass (CPB) is a therapeutic option with considerable risk. We hypothesized that off-pump supraarterial myotomy could be an effective treatment modality. Methods: Between October 1998 and May 2000, 13 patients were referred for surgery. All were symptomatic despite medical therapy. Anteroseptal ischemia had been proven by thallium scintigraphy in all 13 patients, exercise testing was positive in 11. All patients were operated on with an off-pump approach after median sternotomy. Results: Mean patient age was 61 8 years (range, 43-71 years). Coronary artery disease mandating additional bypasses was present in 3 patients. The bypasses were done off pump in 2 patients. Conversion to on-pump surgery was necessary in 3 of 13 patients (23%) because of hemodynamic compromise (1 patient), opening of the right ventricle (1 patient), and injury to the LAD (1 patient). Supraarterial myotomy was performed in all patients. One patient who underwent surgery with CPB developed postoperative anteroseptal myocardial infarction. Postoperative exercise testing was performed in all patients and did not reveal any persistent ischemia. Mortality was 0%. All patients were free from symptoms and had not undergone repeat interventions after an average of 51 7 months of follow-up. Conclusions: Off-pump supraarterial myotomy effectively relieves coronary obstruction but has a certain periprocedural risk as evidenced by 1 myocardial infarction, 1 right ventricular injury, and 1 LAD injury. Long-term freedom from symptoms and from reintervention favor further investigation of this surgical therapy.

OBJECTIVEStenoocclusive cerebral vasculopathy is an infrequent delayed complication of ionizing radiation. It has been well described with photon-based radiation therapy but less so following proton-beam radiotherapy. The authors report their recent institutional experience in evaluating and treating children with radiation-induced cerebral vasculopathy.METHODSEligible patients were age 21 years or younger who had a history of cranial radiation and subsequently developed vascular narrowing detected by MR arteriography that was significant enough to warrant cerebral angiography, with or without ischemic symptoms. The study period was January 2011 to March 2019.RESULTSThirty-one patients met the study inclusion criteria. Their median age was 12 years, and 18 (58%) were male. Proton-beam radiation therapy was used in 20 patients (64.5%) and photon-based radiation therapy was used in 11 patients (35.5%). Patients were most commonly referred for workup as a result of incidental findings on surveillance tumor imaging (n = 23; 74.2%). Proton-beam patients had a shorter median time from radiotherapy to catheter angiography (24.1 months [IQR 16.8–35.4 months]) than patients who underwent photon-based radiation therapy (48.2 months [IQR 26.6–61.1 months]; p = 0.04). Eighteen hemispheres were revascularized in 15 patients. One surgical patient suffered a contralateral hemispheric infarct 2 weeks after revascularization; no child treated medically (aspirin) has had a stroke to date. The median follow-up duration was 29.2 months (IQR 21.8–54.0 months) from the date of the first catheter angiogram to last clinic visit.CONCLUSIONSAll children who receive cranial radiation therapy from any source, particularly if the parasellar region was involved and the child was young at the time of treatment, require close surveillance for the development of vasculopathy. A structured and detailed evaluation is necessary to determine optimal treatment.

Scrub typhus (Orientia tsutsugamushi), is a strict intracellular bacterium which is reported to be a recent threat to parts of southern India. There is re-emergence of scrub typhus during the past few years in Chennai. Scrub typhus is an acute febrile illness which generally causes non-specific symptoms and signs. The clinical manifestations of this disease range from sub-clinical disease to organ failure to fatal disease. This study documents our laboratory experience in diagnosis of scrub typhus in patients with fever and suspected clinical symptoms of scrub typhus infection for a period of two years from April 2014 to April 2016 using immunochromatography and IgM ELISA methods. The study was conducted on 648 patients out of whom 188 patients were found to be positive for scrub typhus. Results also showed that pediatric (0 -12 years) and young adults (20 – 39 years) were more exposed to scrub typhus infection and female patients were more infected compared to male. The study also showed that the rate of infection was higher between September to February which also suggested that the infection rate is proportional to the climatic condition. Statistical analysis showed that the mean age of the patients in this study was 37.6, standard deviation was 18.97, CV % was 50.45.

Abstract Objectives To evaluate objective treatment success and subjective patient-reported outcomes in patients with radiation-induced urethral strictures undergoing single-stage urethroplasty. Patients and methods Monocentric study of patients who underwent single-stage ventral onlay buccal mucosal graft urethroplasty for a radiation-induced stricture between January 2009 and December 2016. Patients were characterized by descriptive analyses. Kaplan–Meier estimates were employed to plot recurrence-free survival. Recurrence was defined as any subsequent urethral instrumentation (dilation, urethrotomy, urethroplasty). Patient-reported functional outcomes were evaluated using the validated German extension of the Urethral Stricture Surgery Patient-Reported Outcome Measure (USS PROM). Results Overall, 47 patients were available for final analyses. Median age was 70 (IQR 65–74). Except for two, all patients had undergone pelvic radiation therapy for prostate cancer. Predominant modality was external beam radiation therapy in 70% of patients. Stricture recurrence rate was 33% at a median follow-up of 44 months (IQR 28–68). In 37 patients with available USS PROM data, mean six-item LUTS score was 7.2 (SD 4.3). Mean ICIQ sum score was 9.8 (SD 5.4). Overall, 53% of patients reported daily leaking and of all, 26% patients underwent subsequent artificial urinary sphincter implantation. Mean IIEF-EF score was 4.4 (SD 7.1), indicating severe erectile dysfunction. In 38 patients with data regarding the generic health status and treatment satisfaction, mean EQ-5D index score and EQ VAS score was 0.91 (SD 0.15) and 65 (SD 21), respectively. Overall, 71% of patients were satisfied with the outcome. Conclusion The success rate and functional outcome after BMGU for radiation-induced strictures were reasonable. However, compared to existing long-term data on non-irradiated patients, the outcome is impaired and patients should be counseled accordingly.

We commonly see patients presenting with either portal hypertensive gastropathy (PHG) or radiation gastritis. Radiation-induced hemorrhagic gastritis is an unusual lethal complication postradiation. Patients with preexisting PHG have very friable mucosa that can easily bleed after radiation for cancer treatment. There is an increased risk of bleeding with both entities present together. Our aim is to focus on treatment and possible prevention of gastrointestinal bleeding in patients with preexisting PHG undergoing radiation therapy for newly diagnosed cancer. Several therapies like prednisolone, argon plasma coagulation, laser coagulation have been proposed. There are no set guidelines for treatment. In these patients, if radiation therapy is indicated either for hepatic or gastrointestinal malignancy, it is suggested to premedicate with proton pump inhibitors or sucralfate. We describe a case of 73-year-old female who presented with upper gastrointestinal bleeding. She had liver cirrhosis secondary to nonalcoholic fatty liver disease and diagnosed with pancreatic cancer, for which she received chemoradiation. She was found to have both radiation gastritis and PHG with diffuse erythematous, edematous, congested mucosa with diffuse oozing blood in the antrum making it very challenging to treat.
