Telemonitoring in heart failure patients treated by cardiac resynchronisation therapy with defibrillator (CRT-D): the TELECART Study.

AIM: Telemonitoring (TM) is a safe and efficient monitoring system for internal cardioverter defibrillator device (ICD) recipients. TM has been used to track info on the clinical status of heart failure patients treated by ICD and/or cardiac resynchronisation therapy defibrillator (CRT-D). The aim of this study was to investigate the impact of TM on clinical outcomes in a population of CRT-D patients with heart failure. METHODS: In a multicentre, randomised study, patients with chronic heart failure, New York Heart Association (NYHA) functional class II or III, left bundle branch block, severe left ventricle ejection fraction reduction (LVEF < 35%) have been identified and screened. RESULTS: One hundred and ninety-one patients have been randomised to receive either a CRT-D with TM or a CRT-D with traditional ambulatory monitoring (control group) and completed the 12-month study follow-up. Primary endpoints were all cause death, cardiac death and hospital admission for heart failure. Secondary endpoints were atrial fibrillation, sustained episodes, non-sustained and self terminated ventricular tachyarrhythmia, sustained ventricular tachycardia, and ventricular fibrillation, ICD shocks and percentage of CRT-D responder patients. Univariate analysis identified the following factors predicting hospitalisation: TM, age, chronic kidney disease, hypercholesterolaemia, LVEF and NYHA class. At multivariate analysis, TM was the only factor predicting heart failure hospitalisation (hazard ratio 0.6, 0.42-0.79, 95% CI, p = 0.002), without affecting overall mortality and cardiac deaths events. CONCLUSIONS: Taken together, our data indicate the importance of TM in predicting heart failure hospitalisation in patients treated with CRT-D.

Profiling cancer gene mutations in longitudinal epithelial ovarian cancer biopsies by targeted next-generation sequencing: a retrospective study.

BACKGROUND: The majority of patients with stage III-IV epithelial ovarian cancer (EOC) relapse after initially responding to platinum-based chemotherapy, and develop resistance. The genomic features involved in drug resistance are unknown. To unravel some of these features, we investigated the mutational profile of genes involved in pathways related to drug sensitivity in a cohort of matched tumors obtained at first surgery (Ft-S) and second surgery (Sd-S). PATIENTS AND METHODS: Matched biopsies (33) taken at Ft-S and Sd-S were selected from the 'Pandora' tumor tissue collection. DNA libraries for 65 genes were generated using the TruSeq Custom Amplicon kit and sequenced on MiSeq (Illumina). Data were analyzed using a high-performance cluster computing platform (Cloud4CARE project) and independently validated. RESULTS: A total of 2270 somatic mutations were identified (89.85% base substitutions 8.19% indels, and 1.92% unknown). Homologous recombination (HR) genes and TP53 were mutated in the majority of Ft-S, while ATM, ATR, TOP2A and TOP2B were mutated in the entire dataset. Only 2% of mutations were conserved between matched Ft-S and Sd-S. Mutations detected at second surgery clustered patients in two groups characterized by different mutational profiles in genes associated with HR, PI3K, miRNA biogenesis and signal transduction. CONCLUSIONS: There was a low level of concordance between Ft-S and Sd-S in terms of mutations in genes involved in key processes of tumor growth and drug resistance. This result suggests the importance of future longitudinal analyses to improve the clinical management of relapsed EOC.

Tuning the catalytic activity of Ag(110)-supported Fe phthalocyanine in the oxygen reduction reaction.

A careful choice of the surface coverage of iron phthalocyanine (FePc) on Ag (110) around the single monolayer allows us to drive with high precision both the long-range supramolecular arrangement and the local adsorption geometry of FePc molecules on the given surface. We show that this opens up the possibility of sharply switching the catalytic activity of FePc in the oxygen reduction reaction and contextual surface oxidation in a reproducible way. A comprehensive and detailed picture built on diverse experimental evidence from scanning tunnelling microscopy, X-ray photoelectron spectroscopy and X-ray absorption spectroscopy, coupled with density functional theory calculations, sheds new light on the nature of the catalytically active molecule-surface coordination and on the boundary conditions for its occurrence. The results are of relevance for the improvement of the catalytic efficiency of metallo-macrocycles as viable substitutes for platinum in the cathodic compartment of low-temperature fuel cells.

Bioelectrical impedance analysis in patients with posterior vitreous detachment.

OBJECTIVE: The purpose of the study is to assess body hydration in patients with posterior vitreous detachment (PVD) by bioelectrical impedance analysis (BIA). PVD, one of the most common eye diseases, is associated in both research and the collective image with reduced daily water intake, but this finding is not supported by strong evidence in the literature. PATIENTS AND METHODS: Based on Spectral Domain Optical Coherence Tomography (SD-OCT) evaluation, different PVD stages are identified: absent posterior vitreous detachment, partial posterior vitreous detachment (P-PVD), or complete posterior vitreous detachment (C-PVD). BIA is a simple, non-invasive bedside method used to assess body composition. Patients underwent BIA and completed a floaters symptoms. 30 patients were enrolled and divided into two groups according to the degree of vitreous detachment, in P-PVD (n=12) and C-PVD (n=18). Patients underwent BIA and completed a floaters symptoms questionnaire. BIA measured the Resistance (R), Reactance (Xc), Phase Angle (PhA), Total Body Water (TBW), Extracellular Water (ECW), Fat Mass (FM), Fat-Free Mass (FFM), and Body Cell Mass Index (BCMI). Finally, patients received a test to assess adherence to the Mediterranean diet (Mediterranean Diet Test Score, MDTS) with the addition of daily water intake. RESULTS: Relevant data were obtained from the BIA evaluation: the values of R and Xc were lower in the P-PVD group than C-PVD group (respectively 417.08±58.12 Ω vs. 476.94±51.29 Ω p=0.006 and 41.33±8.23 Ω vs. 50.61±7.98 Ω p=0.004). Instead, patients in the P-PVD group reported higher values of TBW and ECW than C-PVD group (respectively 44.13±7.57 L vs. 37.96±6.27 L p=0.021 and 21.03±4.06 L vs. 17.24±2.63 L p=0.004). CONCLUSIONS: In the present study, we reported a significant correlation between vitreous pathology and anthropometric and BIA measurements.

Subclinical microvascular changes in ANCA-vasculitides: the role of optical coherence tomography angiography and nailfold capillaroscopy in the detection of disease-related damage.

BACKGROUND: Both cardiovascular and complement-mediated disorders might lead to microvascular damages in anti-neutrophil cytoplasm autoantibodies (ANCA)-associated vasculitides (AAV). We aimed at investigating, for the first time, subclinical microvascular abnormalities with non-invasive techniques in AAV patients by analyzing both retinal and nailfold capillary changes. Retinal plexi were investigated using optical coherence tomography angiography (OCT-A), while nailfold capillary changes by video-capillaroscopy (NVC). Potential correlations between microvessels' abnormalities and disease damage were also explored. METHODS: An observational study was conducted on consecutive patients who met the inclusion criteria of defined diagnosis of eosinophilic granulomatosis with polyangiitis (EGPA), granulomatosis with polyangiitis (GPA), and microscopic polyangiitis (MPA), age ≥ 18 ≤ 75 yrs, and no ophthalmological disorders. Disease activity was assessed by Birmingham Vasculitis Activity Score (BVAS), damage by Vasculitis Damage Index (VDI), and poorer prognosis by the Five Factor Score (FFS). Quantitative analysis of vessel density (VD) was performed by OCT-A in both superficial and deep capillary plexi. Figures and detailed analysis from NVC were performed for all subjects in the study. RESULTS: Included AAV patients (n = 23) were compared with 20 age/sex-matched healthy controls (HC). Retinal VD in superficial whole and parafoveal plexi resulted significantly decreased in AAV compared to HC (P = 0.02 and P = 0.01, respectively). Furthermore, deep whole and parafoveal vessel density was strongly reduced in AAV than HC (P ≤ 0.0001 for both). In AAV patients, significant inverse correlations occurred between VDI and OCTA-VD in both superficial (parafoveal, P = 0.03) and deep plexi (whole, P = 0.003, and parafoveal P = 0.02). Non-specific NVC pattern abnormalities occurred in 82% of AAV patients with a similar prevalence (75%) in HC. In AAV, common abnormalities were edema and tortuosity in a comparable distribution with HC. Correlations between NVC changes and OCT-A abnormalities have not been described. CONCLUSION: Subclinical microvascular retinal changes occur in patients with AAV and correlate with the disease-related damage. In this context, the OCT-A can represent a useful tool in the early detection of vascular damage. AAV patients present microvascular abnormalities at NVC, whose clinical relevance requires further studies.

A literature review of hypertensive retinopathy: systemic correlations and new technologies.

OBJECTIVE: Hypertensive retinopathy (HR) is the most common ocular manifestation of systemic arterial hypertension. This paper aims to summarize the current knowledge of HR, reviewing its classical features, such as epidemiology, pathophysiology, clinical manifestations, classifications, management and the most significant systemic correlations. We also provide an update on the latest advances in new technologies focusing on novel instrumental classifications. MATERIALS AND METHODS: A literature search was performed to identify articles regarding HR listed in Embase, PubMed, Medline (Ovid) and Scopus database up to 1 December 2021. The reference lists of the analyzed articles were also considered a source of literature information. The following keywords were used in various combinations: hypertensive retinopathy, hypertension and eye, hypertensive retinopathy and systemic correlations, optical coherence tomography (OCT) and hypertensive retinopathy, optical coherence tomography angiography (OCTA) and hypertensive retinopathy, adaptive optics (AO) and hypertensive retinopathy. The authors analyzed all English articles found using the aforementioned keywords. All the publications were thoroughly reviewed to create a detailed overview of this issue. RESULTS: HR signs have a significative association with cardiovascular, cerebrovascular and other systemic diseases. Patients with arteriosclerotic changes and, at the same time, severe HR, are at increased risk for coronary disease, peripheral vascular disease, stroke and dementia. HR is even now diagnosed and classified by its clinical appearance on a fundoscopic exam that is limited by interobserver variability. New technologies, like OCT, OCTA, AO and artificial intelligence may be used to develop a new instrumental classification that could become an objective and quantitative method for the evaluation of this disease. They could be useful to evaluate the subclinical retinal microvascular changes due to hypertension that may reflect the involvement of other vital organs. CONCLUSIONS: The eye is the only organ in the human body where changes in the blood vessels due to systemic hypertension can be studied in vivo. All doctors should be familiar with this disease because it has been largely demonstrated that signs of HR are correlated to patient's health and mortality. Researchers should develop a new common, standardized, and objective method to assess hypertensive retinal changes; new technologies may have a significant role in this field. This review takes most of the literature published so far, including the OCTA studies in order to stimulate new points of reference to standardize parameters and new diagnostic markers of this disease.

STM investigation of temperature-dependent two-dimensional supramolecular architectures of C60 and amino-tetraphenylporphyrin on Ag(110).

Multicomponent supramolecular self-assemblies of exceptional long-range order and low defectivity are obtained if C(60) and 5-(4-aminophenyl)-10,15,20-triphenylporphyrin (TPP-NH2) are assembled on Ag(110) by sequential evaporation in the submonolayer range of TPP-NH2 and fullerene on the substrate surface and subsequent annealing. A (+/-2 -3, 6 +/- 3) array consisting of supramolecular stripes of a 1:1 C(60)/TPP-NH2 2D adduct develops at 410 K (the low temperature, LT, phase). If the LT phase is annealed at 470 K, then a 3:1 fullerene/TPP-NH2 (+/-3 -5, 5 +/- 5) nanoporous array (the HT phase) forms, with each pore containing a single porphyrin molecule. Phase separation occurs by annealing the HT phase at 520 K. Structural models are proposed and discussed on the basis of the experimental scanning tunneling microscopy results.

Surgical and oncological outcomes of our first 59 cases of robotic pancreaticoduodenectomy.

PURPOSE: Robotics has shown encouraging results for a number of technically demanding abdominal surgeries including pancreaticoduodenectomy, which has originally represented a relative contraindication to the application of the minimally-invasive technique. We aimed to investigate the perioperative, clinicopathologic, and oncological outcomes of robot-assisted pancreaticoduodenectomy by assessing a consecutive series of totally robotic procedures. METHODS: All consecutive patients who underwent robotic pancreaticoduodenectomy were included in the present analysis. Perioperative, clinicopathologic and oncological outcomes were examined. In order to investigate the role of the learning curve, surgical outcomes were also used to compare the early and the late phase of our experience. RESULTS: A total of 59 patients underwent surgery. Median hospital stay was 9 days (5 - 110), with an overall morbidity and mortality of 37% and 3%, respectively. Of note, the rate of clinically relevant pancreatic fistula was 11.8%. R0 resections were achieved in 96% of patients and the 3-year disease-free and overall survivals were 37.2 and 61.9%, respectively. Overall, surgical outcomes did not vary significantly between the first and the late phase of the series. CONCLUSIONS: Robotic pancreaticoduodenectomy can be performed competently. It satisfies all features of oncological adequacy and may offer a number of advantages over standard procedures in terms of surgical results.

Characteristics of selectors of nicotine replacement therapy.

OBJECTIVE: To assess differences in demographic and smoking characteristics between smokers who have and have not used nicotine replacement therapy (NRT). DESIGN: Mail survey of US smokers from a national research panel. PARTICIPANTS: Smokers 18 years and over who returned a survey on smoking (n = 9630). The sample was weighted to match the US smoker population on age and sex. MAIN OUTCOME MEASURES: Compared smokers who had/had not used NRT in a quit attempt (ever NRT use or over the counter (OTC) NRT use) on: demographic characteristics, nicotine dependence, history of craving and withdrawal, expected difficulty quitting, and self reported history of smoking related medical illness and psychopathology. RESULTS: NRT users (both ever-users and OTC users) were more likely to be older, male, and better educated. They were also heavier smokers, had experienced more craving and withdrawal upon quitting, and scored higher on measures of dependence. These differences were evident among light smokers, and remained even when smoking rate and time to first cigarette were controlled. CONCLUSION: Smokers who elect to use NRT differ from non-NRT users in ways that predispose them to failure in cessation. Controlling for smoking rate and time to first cigarette does not eliminate these differences, even among light smokers. These differences must be considered when comparing the effectiveness of NRT among samples of smokers who self select their treatment and are likely to bias such outcome comparisons.

The efficacy of computer-tailored smoking cessation material as a supplement to nicotine polacrilex gum therapy.

BACKGROUND: Standard, generic self-help materials have been largely ineffective as behavioral treatments for smoking cessation. In contrast, self-help programs tailored to the needs of specific smokers have shown promise in facilitating quitting. OBJECTIVE: To evaluate the incremental efficacy of the Committed Quitters Program (CQP), a set of computer-tailored materials offered to purchasers of nicotine polacrilex gum, compared with a briefuntailored user's guide and audiotape, both as supplements to nicotine replacement therapy. METHODS: We conducted a randomized, open-label trial with 3 parallel arms. Subjects were smokers who purchased 2- or 4-mg nicotine polacrilex gum and called the CQP toll-free enrollment line. Three thousand six hundred twenty-seven subjects consented to participate in 1 of 3 study arms: (1) those receiving the CQP materials (CQP group, n= 1,217), (2) those receiving CQP materials and an outbound telephone call (CQP + C group, n= 1,207); and (3) those receiving no supplemental intervention beyond the user's guide and audiotape that were prepackaged with the nicotine polacrilex gum (UG group, n= 1,203). Twenty-eight-day continuous abstinence rates were assessed by telephone interviews at 6 weeks and 10-week continuous rates at 12 weeks into treatment. RESULTS: Abstinence rates among respondents at the 6- and 12-week assessments were significantly higher for the CQP (36.2% and 27.6%) and CQP + C (35.5% and 27.3%) groups compared with the UG group (24.7% and 17.7%) at both intervals. The quit rates for the CQP and CQP + C groups were almost identical. CONCLUSIONS: The CQP proved to be an effective behavioral treatment, enhancing quit rates over and above nicotine replacement therapy and a brief untailored written guide and audiotape.

Challenges in robotic distal pancreatectomy: systematic review of current practice.

Over the last decade, robotics has gained popularity and is increasingly employed to accomplish several abdominal surgical procedures. Nevertheless, pancreatectomies are regarded as demanding procedures for which the application of minimally-invasive surgery is still limited and its effectiveness has not been conclusively established. We aimed to investigate the current role of robot-assisted surgery to perform distal pancreatectomy. A systematic review of the English-language literature was conducted for articles dealing with robotic-assisted distal pancreatectomies. All relevant papers were evaluated on surgical and oncological outcomes. A total of 10 articles reporting on robotic distal pancreatectomies were finally considered in the analysis, including 259 patients. Mean operative time was 271 minutes (range 181-398); mean blood loss was 210 mL (range 104-361), in 11.6% of cases conversion to laparotomy occurred, spleen preservation was accomplished in 51.4% of procedures, mean time of postoperative hospital stay was 7 days. Overall, postoperative mortality and morbidity were 0% and 23.4% respectively, the mean number of lymph nodes harvested was 12.7. In all included series, no case of R1 resection was reported. Despite its relatively recent introduction in clinical practice, robotic-assisted surgery has been widely employed to perform distal pancreatectomy worldwide and it should be considered a safe and effective procedure. Both surgical and pathologic data support its application in the management of pancreatic lesions of the body and tail.

Robot-assisted surgery for gastric carcinoma: Five years follow-up and beyond: A single western center experience and long-term oncological outcomes.

INTRODUCTION: Robot-assisted surgery for the treatment of gastric cancer is considered to be safe and feasible with early post-operative outcomes comparable to open and laparoscopic series. However, data regarding long-term oncological outcomes are lacking. Aim of this study is to evaluate long-term oncological outcomes of a cohort of gastric cancer patients treated surgically with the robot-assisted approach. MATERIALS AND METHODS: A prospectively collected database of robot-assisted gastrectomies performed for gastric cancer at the 'Misericordia Hospital' between September 2001 and October 2011 was retrospectively analysed. Data regarding surgical procedures, early postoperative course, and long-term follow-up were analysed. RESULTS: The study included 98 consecutive robot-assisted gastrectomies. Fifty-nine distal gastrectomies, 38 total gastrectomies, and 1 proximal gastrectomy. Open conversion occurred in seven patients (7.1%) due to locally advanced disease. Postoperative morbidity and mortality were 12.2% and 4.1% respectively. Post-operative staging showed 46 patients (46.9%) with stage I disease, 25 patients (25.5%) with stage II, 26 (26.5%) with stage III and 1 (1.02%) with stage IV. The mean follow-up was 46.9 months. Cumulative 5-year overall survival (OS) was 73.3% (95% CI: 62.2-84.4). Five-year survival by stage subgroups was 100% for patients with stage IA, 84.6% for stage IB, 76.9% for stage II, and 21.5% for stage III. The only patient in stage IV of this series died eight months after surgery. CONCLUSIONS: Robot-assisted gastrectomy for the treatment of gastric cancer is safe and feasible. It provides long-term outcomes comparable to most open and laparoscopic series. Further studies are necessary to better define its indication.

Right ventricular dilatation after left ventricular acute myocardial infarction is predictive of extremely high peri-infarctual apoptosis at postmortem examination in humans.

BACKGROUND: Cardiac remodelling after acute myocardial infarction (AMI) is characterised by molecular and cellular mechanisms involving both left and right ventricles, and biventricular failure identifies patients with an extremely unfavourable prognosis. AIMS: To assess whether a link exists between increased myocardial apoptotic rates (AR) at sites of recent infarction and patterns of unfavourable cardiac remodelling, such as biventricular enlargement after left ventricular (LV) infarction. METHODS: Twelve patients with recent AMI involving the LV and not the right ventricle (RV) and with permanent infarct related artery occlusion were selected at necropsy. Gross pathological characteristics, such as LV and RV dilatation, and AR at site of infarction were assessed. Potential false positive results (DNA synthesis and RNA splicing) were excluded from the cell count. RESULTS: RV enlargement, defined as a tricuspidal ring greater than 120 mm, was found in five cases and was associated with LV dilatation. These patients showed significantly higher AR than the others. When the subjects were divided into three groups according to progressive cardiac remodelling (absence of cardiac dilatation, isolated LV dilatation, and biventricular enlargement), the last group had significantly higher ARs than the other two groups, showing that myocardiocyte apoptosis is increased in more unfavourable forms of cardiac remodelling. CONCLUSION: Patients with severely unfavourable cardiac remodelling, such as biventricular enlargement, have extremely high myocardiocyte apoptosis at necropsy, even late after LV myocardial infarction, supporting the role of myocardiocyte loss in determining post-infarction adverse remodelling.

Surviving acute myocardial infarction: survivin expression in viable cardiomyocytes after infarction.

BACKGROUND: Apoptosis is a key feature in postinfarction remodelling leading to progressive myocyte loss. Both proapoptotic and antiapoptotic factors contribute to the delicate balance between death and survival. The survivin pathway has emerged as essential in the control of apoptosis, although its role in heart disease is unknown. AIM: To evaluate survivin expression after acute myocardial infarction (AMI). METHODS: Survivin expression was assessed immunohistochemically in the peri-infarct and remote viable myocardium in 17 consecutive patients who died 1-30 weeks after AMI and in four control hearts. RESULTS: Survivin was expressed by myocytes in the peri-infarct area in eight patients and in the remote region in 13 patients. The rate of survivin expression after AMI was significantly higher in the remote versus peri-infarct regions and compared with control hearts. Its expression was inversely associated with the presence of dilated cardiopathy and of apoptosis, independently from the gross pathology infarct size. CONCLUSIONS: Survivin myocardial expression after AMI may be associated with the survival of at risk myocardium and may be indicative of more favourable remodelling after AMI. These findings identify a potential new target for the treatment of postinfarction remodelling.

Comparative efficacy of 24-hour and 16-hour transdermal nicotine patches for relief of morning craving.

AIMS: To compare a transdermal nicotine patch designed for 24-hour wear with one designed for 16-hour wear for relief of craving and withdrawal, particularly in the morning hours. DESIGN: Smokers were randomly assigned to use one of two common patch regimens: NicoDerm/NiQuitin (24-hour wear, 21 mg nicotine) or Nicotrol/Nicorette (16-hour wear, 15 mg). In a double-dummy design, participants wore two patches during the day, one active, one placebo and one patch while sleeping. SETTING: A smoking cessation research clinic. PARTICIPANTS: Two hundred and forty-four smokers who suffered morning cravings. INTERVENTION: Two patch formulations approved and marketed for over-the-counter use in the US--NicoDerm CQ (labeled as 21 mg over 24 hours) and Nicotrol (labeled as 15 mg over 16 hours)--were each used according to its instructions. Smokers also received behavioral counseling. MEASUREMENTS: For a week of baseline and 2 weeks after quitting, smokers used palm-top computers to assess craving and withdrawal symptoms several times each day. FINDINGS: The 21 mg/24-hour patch yielded consistently better control of craving, not only during the morning hours, but throughout the day, and over the 2-week period of abstinence. Additionally, the 21 mg/24-hour patch yielded greater reductions in anxiety, irritability and restlessness. Smokers using the 21 mg/24-hour dosing regimen also experienced longer abstinence than those using the 15 mg/16-hour patch. CONCLUSIONS: These findings demonstrate that 24-hour dosing with a 21 mg patch affords superior relief of craving and withdrawal during the first 2 weeks of abstinence, when symptoms are at their peak, and when relapse is most likely. They confirm the importance of dosing parameters in nicotine replacement products.

The efficacy of computer-tailored smoking cessation material as a supplement to nicotine patch therapy.

The study evaluated the efficacy of the Committed Quitters Program (CQP), a computer-tailored set of printed behavioral support materials offered free to purchasers of NicoDerm CQ patches, as a supplement to the nicotine patch and the standard brief User's Guide (UG) and audiotape. Callers to the CQP enrollment were randomized to either CQP (n=1854) or just the UG (n=1829). Abstinence and use of program materials were assessed by telephone interview at 6 and 12 weeks (the latter falling 2 weeks after patch use was to be discontinued). Considering all respondents, abstinence rates did not differ significantly between the UG and CQP groups. As expected, among those who reported they used their assigned materials (80.1% of the sample) smokers who received CQP demonstrated higher quit rates at both 6 weeks (38.8% v. 30.7%) and 12 weeks (18.2% v. 11.1%), compared to the UG group. Among those who used it, the Committed Quitters Program proved to be an effective behavioral treatment, improving quit rates over nicotine replacement therapy and a brief untailored written guide and audiotape.

Lymphomatoid granulomatosis of the lung: a clinico-pathological study.

Lymphomatoid granulomatosis is the only form of pulmonary angiitis histologically characterized by a necrotizing angiocentric and angiodestructive lymphoid infiltrate, with an admixed T-cell reaction. We evaluated three patients with a single lung nodule not diagnosed by routine radiological and endoscopic assays. Our investigations showed a prevalence of T-cells in areas of diffuse infiltration, which were actively replacing reactive follicular areas of B-cells, similarly to T-cell lymphomas. Further pathologic assays suggested the histologic diagnosis of grade I lymphomatoid granulomatosis for all three evaluated specimens. After two years, patients treated with a combination of surgical resection and chemotherapy were disease free, supporting the efficacy of aggressive therapy in the management of this often mistreated group of lymphoid proliferations.
