ABSTRACT
The prognosis of cancer patients has greatly improved in the last years, owing to the development of novel chemotherapeutic agents. However, this progress comes with an increasing occurrence of cardiovascular adverse reactions. A serious side effect is arterial hypertension (HT), which is the most frequent comorbidity encountered in cancer patients, influencing the outcomes in cancer survivors. Even though secondary HT related to specific chemotherapeutic agents, such as vascular endothelial growth factor inhibitors, is usually mild and reversible, in rare instances it can be severe, leading to discontinuation of chemotherapy. In addition, HT per se has been studied as a potential risk factor for cancer development. The relationship is even more complex than previously thought, as concerning evidence recently highlighted the potential oncogenic effects of antihypertensive drugs, particularly thiazide diuretics, which may increase the risk of skin cancer. As a result, in light of the similar risk factors and overlapping pathophysiological mechanisms between HT and cancer, a promising concept of onco-hypertension has emerged, aiming to improve the understanding of the complicated interplay between these two pathologies and maintain a balance between the efficacy and risks of both antihypertensive drugs and chemotherapy agents.

Stenotrophomonas maltophilia is a Gram-negative bacillus that causes skin and soft tissue infections (SSTI), as well as bacteremia, pneumonia, and urinary tract infections. S. maltophilia infections are typically nosocomial and are often transmitted through water sources. Although historically described in immunocompromised hosts, S. maltophilia prevalence is increasing in both immunocompromised and immunocompetent populations. In light of high morbidity and mortality, it is critical that dermatologists are aware of this organism because of the limited options for therapy. Here, we describe a case of a S. maltophilia abscess with bacteremia in a patient with chronic lymphocytic leukemia and aplastic anemia that was successfully treated with trimethoprim-sulfamethoxazole. We also review the current standard of care and propose an algorithm for the treatment of S. maltophilia infection.
ABSTRACT
Hypertensive emergencies (HE) represent high cardiovascular risk situations defined by a severe increase in blood pressure (BP) associated with acute, hypertension mediated organ damage (A-HMOD) to the heart, brain, retina, kidneys, and large arteries. Blood pressure values alone do not accurately predict the presence of HE; therefore, the search for A-HMOD should be the first step in the management of acute severe hypertension. A rapid therapeutic intervention is mandatory in order to limit and promote regression of end-organ damage, minimize the risk of complications, and improve patient outcomes. Drug therapy for HE, target BP, and the speed of BP decrease are all dictated by the type of A-HMOD, specific drug pharmacokinetics, adverse drug effects, and comorbidities. Therefore, a tailored approach is warranted. However, there is currently a lack of solid evidence for the appropriate treatment strategies for most HE. This article reviews current pharmacological strategies while providing a stepwise, evidence based approach for the management of HE.
ABSTRACT
Purpose of Review: Neutrophilic dermatoses are defined by the presence of a sterile neutrophilic infiltrate on histopathology. This review focuses on the pathogenesis, epidemiology, clinicopathological features, diagnosis, and management of four disorders: Sweet syndrome, pyoderma gangrenosum, Behçet syndrome, and neutrophilic eccrine hidradenitis. Recent Findings: Recent studies have provided insight into the complex pathogenesis of neutrophilic dermatoses. Evidence supports an intricate interplay of abnormal neutrophil function and inflammasome activation, malignant transformation into dermal infiltrating neutrophils, and genetic predisposition. Summary: Neutrophilic dermatoses have diverse cutaneous and extracutaneous manifestations and may be associated with significant morbidity and mortality. Common underlying associations include infectious, inflammatory, and neoplastic disorders, as well as drug reactions. Emerging diagnostic and therapeutic frameworks identify an expanding role for biologic and targeted anti-inflammatory therapies.
ABSTRACT
Resistant hypertension (R-HTN) implies a higher mortality and morbidity compared to non-R-HTN due to increased cardiovascular risk and associated adverse outcomes-greater risk of developing chronic kidney disease, heart failure, stroke and myocardial infarction. R-HTN is considered when failing to lower blood pressure below 140/90 mmHg despite adequate lifestyle measures and optimal treatment with at least three medications, including a diuretic, and usually a blocker of the renin-angiotensin system and a calcium channel blocker, at maximally tolerated doses. Hereby, we discuss the diagnostic and therapeutic approach to a better management of R-HTN. Excluding pseudoresistance, secondary hypertension, white-coat hypertension and medication non-adherence is an important step when diagnosing R-HTN. Most recently different phenotypes associated to R-HTN have been described, specifically refractory and controlled R-HTN and masked uncontrolled hypertension. Optimizing the three-drug regimen, including the diuretic treatment, adding a mineralocorticoid receptor antagonist as the fourth drug, a ß-blocker as the fifth drug and an α1-blocker or a peripheral vasodilator as a final option when failing to achieve target blood pressure values are current recommendations regarding the correct management of R-HTN.
ABSTRACT
International drug regulators use conditional drug approval mechanisms to facilitate faster patient access to drugs based on a lower evidentiary standard typically required of drug approvals. Faster and earlier access is justified by limiting eligibility to drugs intended for serious and life-threatening diseases and by requiring post-market evidence collection to confirm clinical benefit. One such mechanism in Canada, the Notice of Compliance with Conditions (NOC/c) policy, was introduced in 1998. Today, most of the drugs approved under the NOC/c policy are for oncology indications. We analyze oncology drugs approvals under the NOC/c policy to inform discussions of two tradeoffs applied to conditional drug approvals, eligibility criteria and post-market evidence. Our analysis informs recommendations for Canada's proposed regulatory reforms approach to conditional approvals pathways. Our analysis demonstrates that under the current policy, eligibility criteria are insufficiently defined, resulting in their inconsistent application by Health Canada. Regulatory responsiveness to post-market evidence from post-market clinical trial and foreign jurisdiction regulatory decisions is slow and insufficient. In the absence of sufficient regulatory responsiveness, physicians and patients must make clinical decisions without the benefit of the best available evidence. Together, our analysis of the two core tradeoffs in Canada's conditional drug approval provides insight to inform the further development of Canada's proposed agile regulatory approach to drugs and devices that will expand the use of terms and conditions.
ABSTRACT
Invasive coronary angiography (ICA) is the gold standard in Coronary Artery Disease (CAD) imaging. Detection of the end-diastolic frame (EDF) and, in general, cardiac phase detection on each temporal frame of a coronary angiography acquisition is of significant importance for the anatomical and non-invasive functional assessment of CAD. This task is generally performed via manual frame selection or semi-automated selection based on simultaneously acquired ECG signals - thus introducing the requirement of simultaneous ECG recordings. In this paper, we evaluate the performance of a purely image based workflow relying on deep neural networks for fully automated cardiac phase and EDF detection on coronary angiographies. A first deep neural network (DNN), trained to detect coronary arteries, is employed to preselect a subset of frames in which coronary arteries are well visible. A second DNN predicts cardiac phase labels for each frame. Only in the training and evaluation phases for the second DNN, ECG signals are used to provide ground truth labels for each angiographic frame. The networks were trained on 56,655 coronary angiographies from 6820 patients and evaluated on 20,780 coronary angiographies from 6261 patients. No exclusion criteria related to patient state (stable or acute CAD), previous interventions (PCI or CABG), or pathology were formulated. Cardiac phase detection had an accuracy of 98.8 %, a sensitivity of 99.3 % and a specificity of 97.6 % on the evaluation set. EDF prediction had a precision of 98.4 % and a recall of 97.9 %. Several sub-group analyses were performed, indicating that the cardiac phase detection performance is largely independent from acquisition angles, the heart rate of the patient, and the angiographic view (LCA / RCA). The average execution time of cardiac phase detection for one angiographic series was on average less than five seconds on a standard workstation. We conclude that the proposed image based workflow potentially obviates the need for manual frame selection and ECG acquisition, representing a relevant step towards automated CAD assessment.

BACKGROUND: Obstructive sleep-disordered breathing (OSDB) is very common in children. Adenotonsillectomy is usually curative, but there is emerging evidence that topical nasal steroids can also be effective for some children and may avoid the need for surgery. The number of children referred for assessment of OSDB is increasing and in some departments, waiting times are long. We established a paediatrician-led clinic for assessment and initial medical management of OSDB and in this study we report the proportion of children who avoided the need for surgery. METHOD: Referral letters to the otolaryngology department were screened and those with suspected OSDB and no significant co-morbidities were diverted to the paediatrician-led clinic. We recorded data for a consecutive series of children seen in this clinic with suspected OSDB over a 3-month period. Parents completed a 5-item subset of questions from the OSA-11 questionnaire before and after treatment with 6 weeks of topical nasal steroids. RESULTS: In the 3-month study period, 103 children were seen, with a mean age of 6 (range 1-16). Six (5.8%) had improved spontaneously before clinic attendance. Of the 97 children who were still symptomatic, 17 (17.5%) were referred directly for surgery on the basis of the severity of their symptoms, or because of other coexisting conditions that required surgical treatment (such as recurrent tonsillitis or otitis media). Three declined intranasal steroids. Seventy-seven had a trial of intranasal steroids, of whom 34 (35%) reported enough improvement to avoid surgery, and 29 (28%) failed to improve and were referred for surgery. Fourteen (14%) failed to attend after the trial of steroids: of these, 5 (5%) were contactable by phone and confirmed improvement after topical steroids. OSA-5 scores were significantly improved following intranasal steroids. DISCUSSION: A paediatrician-led clinic can be an effective way to ease the workload of an over-stretched otolaryngology service, and judicious use of topical nasal steroids can help around 40% of children with OSDB avoid surgery.

Argyria is a rare but cosmetically distressing and difficult-to-treat condition for which quality-switched (Q-switched) lasers have been most commonly employed. However, at least one previous report suggests that the picosecond alexandrite laser may also serve as a successful treatment modality. Herein, we present a side-by-side comparison of a picosecond 755-nm alexandrite laser and a Q-switched 1064-nm neodymium-doped yttrium aluminum garnet (Nd:YAG) laser in the treatment of argyria. Our results reveal an equivalent success of the picosecond alexandrite when compared to the more commonly employed Q-switched Nd:YAG, suggesting that the picosecond 755-nm alexandrite laser is equally effective in the treatment of argyria.
ABSTRACT
Quality of care in medicine is not necessarily proportional to quantity of care and excess is often useless or even more, potentially detrimental to our patients. Adhering to the European Federation of Internal Medicine's initiative, the Romanian Society of Internal Medicine (SRMI) launched the Choosing Wisely in Internal Medicine Campaign, aiming to cut down diagnostic procedures or therapeutics overused in our country. A Working Group was formed and from 200 published recommendations from previous international campaigns, 36 were voted as most important. These were submitted for voting to the members of the SRMI and posted on a social media platform. After the two voting rounds, the top six recommendations were established. These were: 1. Stop medicines when no further benefit is achieved or the potential harms outweigh the potential benefits for the individual patient. 2. Don't use antibiotics in patients with recent C. difficile without convincing evidence of need. 3. Don't regularly prescribe bed rest and inactivity following injury and/or illness unless there is scientific evidence that harm will result from activity. Promote early mobilization. 4. Don't initiate an antibiotic without an identified indication and a predetermined length of treatment or review date. 5. Don't prescribe opioids for treatment of chronic or acute pain for sensitive jobs such as operating motor vehicles, forklifts, cranes or other heavy equipment. 6. Transfuse red cells for anemia only if the hemoglobin concentration is less than 7 g/dL or if the patient is hemodynamically unstable or has significant cardiovascular or respiratory comorbidity. Don't transfuse more units of blood than absolutely necessary.

BACKGROUND: The largest European Roma community resides in Romania, but there is still little published data on cardiovascular (CV) risk factors and disease in this group. This study addresses the prevalence of arterial hypertension, associated CV disease risk, and target organ damage (TOD) in a Roma community from Bucharest, Romania. METHODS: This is a cross-sectional community-based participatory research to assess for CV risk factors, TOD and CV disease, including 806 Roma ethnics (18-83 years) integrated in the local community, 36.16% males. Evaluation included physical examination with blood pressure, pulse wave velocity and anklebrachial measurements, laboratory tests, ECG, echocardiography and fundoscopy. RESULTS: Prevalence of hypertension was 33.62%, awareness 76.38%, higher in females (p>0.01), and control rate 44.39%. Compared to age-matched normotensives, hypertensives had more left ventricle hypertrophy and more frequently increased pulse pressure. Differences in TOD were attenuated between newly and previously diagnosed, controlled and uncontrolled, hypertensives. Cardiovascular disease was almost absent in normotensives. Ten-year risk for fatal CV disease followed an increasing trend from normotension to long standing hypertension. CONCLUSION: This is the first dedicated study to thoroughly assess TOD and risk for fatal CV disease in a Romanian Roma population. Hypertension was less prevalent than in the general population, with similar awareness, possibly as a consequence of integration in the surrounding community. Fatal CV disease risk followed the trend of increasing prevalence of risk factors, and hypertension played an important role in its modulation.
ABSTRACT
BACKGROUND: The Roma population has a high prevalence of cardiovascular risk factors, higher mortality, and shorter life expectancy. It is found in the largest number in Romania, but published data are still scarce here. We studied cardiovascular risk factors and disease along with target organ damage on a population of Roma inhabitants from Bucharest, Romania. METHODS: This cross-sectional study enrolled 806 Roma subjects (18-83 years), in a community-based participatory research manner. Demographics included anthropometric data, a questionnaire on social status, education, medical history, and health deleterious behaviors. Medical evaluation included clinical examination, blood pressure, ankle-brachial index, pulse wave velocity measurements, blood tests (complete blood count, lipid profile, glucose, creatinine, uric acid), dip-stick microalbuminuria, dilated fundoscopy, ECG, and echocardiography. RESULTS: Prevalence of all cardiovascular risk factors was high, peaking in abnormal lipid metabolism (82.13%), heavy smoking (63.02% including ex-smokers) and obesity (50.99%). The first and the latter were actually similar to the general population in Romania. Almost half of subjects were at high or very high risk for fatal cardiovascular disease. CONCLUSIONS: The study shows that the Roma population in a more affluent region in Romania shares a similarly high cardiovascular burden to their surrounding community.

Dietary change may play a role in the therapy of rosacea. Certain foods and beverages may act as "triggers" for rosacea exacerbations. These may be divided into heat-related, alcohol-related, capsaicin-related, and cinnamaldehyde-related. One potential pathogenic mechanism may be via the activation of transient receptor potential cation channels, which result in neurogenic vasodilatation. Further research is needed on the role of the gut skin connection in rosacea. Epidemiologic studies suggest that patients with rosacea have a higher prevalence of gastrointestinal disease, and one study reported improvement in rosacea following successful treatment of small intestinal bacterial overgrowth. While further research is required in this area, patients may be advised on measures to support a healthy gut microbiome, including the consumption of a fiber-rich (prebiotic) diet.
ABSTRACT
INTRODUCTION: Pulmonary thromboembolism (PTE) represents a medical emergency and is the third most common cause of mortality after myocardial infarction and stroke. The purpose of this study was to describe the characteristics and management of patients with PTE admitted in a referral emergency hospital in Romania. MATERIAL AND METHODS: We retrospectively reviewed all cases of PTE diagnosed in one of the largest emergency hospitals in Bucharest during a 2-year period (January 2014 - December 2016). Patients with acute PTE were identified by a database search of the diagnostic codes of all discharge diagnoses. Demographic, clinical and paraclinical tests data was retrieved from medical records. RESULTS: 221 patients (48.87% male, mean age 61.76 years (range 21-94 years)) were diagnosed with PTE in our hospital (0.31% of all hospitalizations). Dyspnea was the most frequent symptom reported (78.9%), followed by pleuritic chest pain (23.9%) and unilateral leg pain (15.8%). Upon presentation, 12.6% of patients had high-risk PTE. Up to 72.8% of patients had at least one thrombotic risk factor, while cancer (14%) was the most frequent amongst them. The mean length of hospitalization was 10.3 ± 4.6 days. Unfractioned heparin (UFH) was the preferred anticoagulant during hospital stay (73.7%, p < 0.001). Vitamin K antagonists (AVK) were the preferred anticoagulant (71.7%, p < 0.001) after discharge, whereas non-antivitamin K oral anticoagulants (NOAC) were recommended in 26.3% of patients. Thrombolysis was used in 18 (8.4%) cases. Mortality was 0.9%. Younger patients more frequently associated thrombophilia or a previous thromboembolic event and clinical signs of DVT at presentation. Older patients associated more frequently a history of hospitalization for heart failure or atrial fibrillation during the previous 3 months and a history of cancer. The clinical presentation in older patients was more severe, with higher PESI scores (103.6 ± 33.4 vs. 55.5 ± 17.9, p<0.001) and a longer hospital stay (10.7 ± 4.7 vs. 9.2 ± 3.9, p = 0.03). The type of anticoagulant treatment did not differ depending on age. CONCLUSION: In our emergency hospital, PTE is a relatively rare cause of hospitalization; the rate is, however, comparable with other major hospitals. Dyspnea and pleuritic chest pain was the clinical presentation dyad. UFH was the preferred anticoagulant for in-hospital treatment while AVK was the preferred option for long term treatment and recurrence prophylaxis; however an increasing number of patients are prescribed NOAC. In older patients clinical severity was higher upon presentation, hospitalization duration was increased and cancer was more frequently associated. Younger patients associated more frequently a primary hypercoagulable state and recurrent thromboembolism. Mortality rate was low during hospitalization, comparable with that seen in other studied populations.

BACKGROUND: This review seeks to synthesize emerging literature on the effects of back muscle size on outcomes in spine surgery. Risk factors that contribute to poor surgical outcomes continue to be an area of interest in spine surgery because proper risk stratification can result in reduction in morbidity and enhanced patient care. However, the impact of muscle size on spine surgical outcomes is an understudied avenue with paucity of data evaluating the relationship among back muscles and surgical outcomes, patient's quality of life, and functional improvement postoperatively. METHODS: This review was centered around identifying studies that assessed the impact of back muscle size on spine surgery outcomes. RESULTS: Five retrospective studies were selected for review. All studies set out to see if differences in muscle size existed in patients with disparate post-operative outcomes as a primary objective. The studies support the association between larger back muscles and improved outcomes. The size and relative cross sectional area of paraspinal muscles and the size of the psoas muscle were associated with functional outcomes, incidence of complications and also fusion rates. CONCLUSION: With reduction in surgical complications and improvement in postoperative functional outcomes, back muscle morphometry ought to be included in the preoperative surgical planning as a predictor of outcomes.
