RESUMO

BACKGROUND: Palpable nodes were exclusionary in American College of Surgeons Oncology Group (ACOSOG) Z0011, while SINODAR-ONE excluded those with positive axillary nodes by palpation and ultrasound. To determine whether clinical nodal status should be exclusionary in those fulfilling pathologic criteria for ACOSOG Z0011 and similar trials, this study analyzed the accuracy and implications of clinical nodal positivity. METHODS: Patients ≥ 18 years old with cT1-T2, cN0-cN1, M0 breast cancer were identified in the National Cancer Database between 2004 and 2019. Subset characteristics of cN1 and cN0 were compared with respect to final pathologic nodal status and overall survival (OS). RESULTS: Of 57,823 patients identified, 77.0% were cT1 and 23.0% were cT2. Of the 93.9% of patients who were staged as cN0, 16.7% were pN1; of the remaining 6.1% staged as cN1, 9.6% were found to be pN0. Among cN1/pN0 patients, 14.9% underwent axillary dissection without sentinel node biopsy. There was no difference in adjusted OS for patients staged as cN0 versus cN1 who were found to be pN1 (HR 1.13, 95% CI 0.93-1.37, p = 0.22), a finding that persisted on subset analysis in those with two positive nodes (HR 0.91, 95% CI 0.62-1.33, p = 0.63). CONCLUSIONS: Clinical nodal stage does not affect OS in pN1 patients. Clinical nodal assessment can both overstage patients and result in unnecessary axillary surgery. These data suggest that cN1 patients who are otherwise candidates for a Z0011-like paradigm should still be considered eligible. Their final candidacy should be determined by surgical lymph node pathology and not preoperative clinical status.

RESUMO

INTRODUCTION: Cervical lymphadenopathy in children is typically self-limited; however, the management of persistent lymphadenopathy remains unclear. This study aimed to evaluate the management and outcomes of patients with persistent cervical lymphadenopathy. METHODS: Single-institution, retrospective review of children <18 years undergoing ultrasound (US) for cervical lymphadenopathy from 2013 to 2021 was performed. Patients were stratified into initial biopsy, delayed biopsy, or no biopsy groups. Clinical characteristics and workup were compared, and multivariate analyses were performed to assess predictors of delayed biopsy. RESULTS: 568 patients were identified, with 493 patients having no biopsy, 41 patients undergoing initial biopsy, and 34 patients undergoing delayed biopsy. Presenting symptoms differed: no biopsy patients were younger, were more likely to present to the emergency department, and had clinical findings often associated with acute illness. Patients with USs revealing abnormal vascularity or atypical architecture were more likely to be biopsied. History of malignancy, symptoms >1 week but <3 months, and atypical or change in architecture on US was associated with delayed biopsy. Patients with long-term follow-up (LTF) were followed for a median of 99.0 days. Malignancies were identified in 12 patients (2.1%). All malignancies were diagnosed within 14 days of presentation, and no malignancies were identified in LTF. CONCLUSIONS: Patients with persistent low suspicion lymphadenopathy are often followed for long durations; however, in this cohort, no malignancies were diagnosed during LTF. We propose an algorithm of forgoing a biopsy and employing primary care surveillance and education, which may be appropriate for these patients in the proper setting.

RESUMO

Background and Objectives: Cervical cancer is the fourth most frequent type of neoplasia in women. It is most commonly caused by the persistent infection with high-risk strands of human papillomavirus (hrHPV). Its incidence increases rapidly from age 25 when routine HPV screening starts and then decreases at the age of 45. This reflects both the diagnosis of prevalent cases at first-time screening and the likely peak of HPV exposure in early adulthood. For early stages, the treatment offers the possibility of fertility preservation.. However, in more advanced stages, the treatment is restricted to concomitant chemo-radiotherapy, combined, in very selected cases with surgical intervention. After the neoadjuvant treatment, an imagistic re-evaluation of the patients is carried out to analyze if the stage of the disease remained the same or suffered a downstaging. Lymph node downstaging following neoadjuvant treatment is regarded as an indubitable prognostic factor for predicting disease recurrence and survival in patients with advanced cervical cancer. This study aims to ascertain the important survival role of radiotherapy in the downstaging of the disease and of lymphadenectomy in the control of lymph node invasion for patients with advanced-stage cervical cancer. Material and Methods: We describe the outcome of patients with cervical cancer in stage IIIC1 FIGO treated at Bucharest Oncological Institute. All patients received radiotherapy and two-thirds received concomitant chemotherapy. A surgical intervention consisting of type C radical hysterectomy with radical pelvic lymphadenectomy was performed six to eight weeks after the end of the neoadjuvant treatment. Results: The McNemar test demonstrated the regression of lymphadenopathies after neoadjuvant treatment-p: <0.001. However, the persistence of adenopathies was not related to the dose of irradiation (p: 0.61), the number of sessions of radiotherapy (p: 0.80), or the chemotherapy (p: 0.44). Also, there were no significant differences between the adenopathies reported by imagistic methods and those identified during surgical intervention-p: 0.62. The overall survival evaluated using Kaplan-Meier curves is dependent on the post-radiotherapy FIGO stage-p: 0.002 and on the lymph node status evaluated during surgical intervention-p: 0.04. The risk factors associated with an increased risk of death were represented by a low preoperative hemoglobin level (p: 0.003) and by the advanced FIGO stage determined during surgical intervention (p-value: 0.006 for stage IIIA and 0.01 for stage IIIC1). In the multivariate Cox model, the independent predictor of survival was the preoperative hemoglobin level (p: 0.004, HR 0.535, CI: 0.347 to 0.823). Out of a total of 33 patients with neoadjuvant treatment, 22 survived until the end of the study, all 33 responded to the treatment in varying degrees, but in 3 of them, tumor cells were found in the lymph nodes during the intraoperative histopathological examination. Conclusions: For advanced cervical cancer patients, radical surgery after neoadjuvant treatment may be associated with a better survival rate. Further research is needed to identify all the causes that lead to the persistence of adenopathies in certain patients, to decrease the FIGO stage after surgical intervention, and, therefore, to lower the risk of death. Also, it is mandatory to correctly evaluate and treat the anemia, as it seems to be an independent predictor factor for mortality.

RESUMO

Sarcoidosis is a sterile non-necrotizing granulomatous disease without known causes that can involve multiple organs with a predilection for the lung and thoracic lymph nodes. Worldwide it is estimated to affect 2-160/100,000 people and has a mortality rate over 5 years of approximately 7%. For sarcoidosis patients, the cause of death is due to sarcoid in 60% of the cases, of which up to 80% are from advanced cardiopulmonary failure (pulmonary hypertension and respiratory microbial infections) in all races except in Japan were greater than 70% of the sarcoidosis deaths are due to cardiac sarcoidosis. Scadding stages for pulmonary sarcoidosis associates with clinical outcomes. Stages I and II have radiographic remission in approximately 30%-80% of cases. Stage III only has a 10%-40% chance of resolution, while stage IV has no change of resolution. Up to 40% of pulmonary sarcoidosis patients progress to stage IV disease with lung parenchyma fibroplasia, bronchiectasis with hilar retraction and fibrocystic disease. These patients are at highest risk for the development of precapillary pulmonary hypertension, which may occur in up to 70% of these patients. Sarcoid patients with pre-capillary pulmonary hypertension can respond to targeted pulmonary arterial hypertension medications. Stage IV fibrocytic sarcoidosis with significant pulmonary physiologic impairment, >20% fibrosis on HRCT or pre-capillary pulmonary hypertension have the highest risk of mortality, which can be >40% at 5-years. First line treatment for patients who are symptomatic (cough and dyspnea) with parenchymal infiltrates and abnormal pulmonary function testing (PFT) is oral glucocorticoids, such as prednisone with a typical starting dose of 20-40 mg daily for 2 weeks to 2 months. Prednisone can be tapered over 6-18 months if symptoms, spirometry, PFTs, and radiographs improve. Prolonged prednisone may be required to stabilize disease. Patients requiring prolonged prednisone ≥10 mg/day or those with adverse effects due to glucocorticoids may be prescribed second and third line treatements. Second and third line treatments include immunosuppressive agents (e.g., methotrexate and azathioprine) and anti-tumor necrosis factor (TNF) medication; respectively. Effective treatments for advanced fibrocystic pulmonary disease are being explored. Despite different treatments, relapse rates range from 13% to 75% depending on the stage of sarcoid, number of organs involved, socioeconomic status, and geography. CONCLUSION: The mortality rate for sarcoidosis over a 5 year follow up is approximately 7%. Unfortunately, 10%-40% of patients with sarcoidosis develop progressive pulmonary disease, and >60% of deaths resulting from sarcoidosis are due to advance cardiopulmonary disease. Oral glucocorticoids are the first line treatment, while methotrexate and azathioprine are considered second and anti-TNF agents are third line treatments that are used solely or as glucocorticoid sparing agents for symptomatic extrapulmonary or pulmonary sarcoidosis with infiltrates on chest radiographs and abnormal PFT. Relapse rates have ranged from 13% to 75% depending on the population studied.

RESUMO

AIM: The major clinical manifestations multisystem inflammatory syndrome in children (MIS-C) are fever, gastrointestinal and cardiac. The aim of this study was to describe MIS-C in a series of patients who presented primarily with cervical manifestations. METHODS: We retrospectively reviewed medical records of all patients who met the Centers for Disease Control and Prevention and World Health Organization MIS-C diagnostic criteria treated at Hadassah-Hebrew University Medical Center between April 2020 and September 2021. RESULTS: Of 37 children diagnosed with MIS-C (median age: 10.2 years, range 1.5-18 years, 20 male) five, 13.5% (median age: 14.4 years, range 9.2-17.5 years) presented with cervical symptoms mimicking neck infections. One was hospitalised with a working diagnosis of retropharyngeal abscess, and four with acute cervical lymphadenitis that did not respond to early antibiotic treatment. All developed full MIS-C phenotype. CONCLUSION: MIS-C may present as cervical inflammation. An ill-appearing child with symptoms and/or signs of cervical inflammation should be evaluated for clinical and laboratory features of MIS-C, thereby facilitating prompt treatment of this potentially fatal disorder.

RESUMO

INTRODUCTION: Studies support omission of axillary lymph node dissection (ALND) for patients with sentinel node-positive disease, with ALND recommended for patients who present with clinically positive nodes. Here, we evaluate patient and tumor characteristics and pathologic nodal stage of patients with estrogen receptor-positive (ER +) breast cancer who undergo ALND to determine if differences exist based on nodal presentation. MATERIALS AND METHODS: Retrospective chart review from 2010 to 2019 defined three groups of patients with ER + breast cancer who underwent ALND for positive nodes: SLN + (positive node identified at SLN biopsy), cNUS (abnormal preoperative US and biopsy), and cNpalp (palpable adenopathy). Patients who received neoadjuvant chemotherapy or presented with axillary recurrence were excluded. RESULTS: Of 191 patients, 94 were SLN + , 40 were cNUS, and 57 were cNpalp. Patients with SLN + compared with cNpalp were younger (56 vs 64 years, p < 0.01), more often pre-menopausal (41% vs 14%, p < 0.01), and White (65% vs 39%, p = 0.01) with more tumors that were low-grade (36% vs 8%, p < 0.01). Rates of PR + (p = 0.16), levels of Ki67 expression (p = 0.07) and LVI (p = 0.06) did not differ significantly among groups. Of patients with SLN + disease, 64% had pN1 disease compared to 38% of cNUS (p = 0.1) and 40% of cNpalp (p = 0.01). On univariable analysis, tumor size (p = 0.01) and histology (p = 0.04) were significantly associated with pN1 disease, with size remaining an independent predictor on multivariable analysis (p = 0.02). CONCLUSION: Historically, higher risk features have been attributed to patients with clinically positive nodes precluding omission of ALND, but when restricting evaluation to patients with ER + breast cancer, only tumor size is associated with higher nodal stage.

RESUMO

The term 'burned-out' tumour of the testis describes a spontaneously and completely regressed testicular tumour that presents at the stage of metastasis. We report three cases of burned-out testicular tumour to illustrate their clinical, radiological and histopathological features and to discuss the hypothesis of the efficacy of early adjuvant chemotherapy without a previous retroperitoneal lymph node biopsy. Subsequent to radical orchiectomy, each pathohistology report revealed testicular hypotrophy or microcalcifications, with no clearly visible germ cell tumours within the specimen. Additionally, following surgery, the patients received the standard (cisplatin-etoposide-bleomycin) chemotherapy protocol, which in two out of three cases showed a complete response. Only one examinee revealed a partial response and received salvage chemotherapy, but he remained in the remission phase during the last follow-up. This study illustrates the value of the early administration of adjuvant chemotherapy in patients with burned-out testicular tumour, which offers the possibility of omitting the diagnostic retroperitoneal lymph node biopsy. Considering the low threshold for testicular malignancy, it is clearly of the utmost importance that these rare patients be treated in a timely manner and without adjunctive procedures (lymph node biopsy) leading to additional morbidity.

RESUMO

Few case reports and series reported abdominal lymphadenopathy (ALN) in people with Gaucher disease (GD). However, it's prevalence among Gaucher population, clinical implications and potential biomarkers are unknown. Hence this study aims to assess the prevalence of ALN among children with GD & to correlate it to neutrophil-lymphocytic-ratio (NLR), platelet-lymphocytic-ratio (PLR) and glucosylsphingosine (Lyso-GL1). Fifty children with GD (14 type-1 and 36 type-3) on enzyme-replacement therapy (ERT) were compared to 50 matched healthy controls, focusing on history of pressure manifestations by ALN (diarrhea, constipation, abdominal pain, intestinal obstruction), and history of splenectomy, with calculation of severity scoring index (SSI). NLR, PLR and Lyso-GL1 were measured. Abdominal-ultrasound was done with assessment of liver and spleen volumes and ALN. CT-scan was done for those having significant lymphadenopathy. Twenty-six children with GD had ALN (52%). The most common presentations were abdominal-pain (22%) & constipation (18%), with intestinal-obstruction in 3 children (6%). Children with GD had significantly higher NLR (p < .001) and decreased PLR (p = .024) compared to controls. Interestingly, children with GD having ALN had significantly higher SSI (.012), Lyso-GL1 (p = .002) and NLR (p = .001) than those without ALN. Multivariate-logistic regression showed that ALN was independently related to Lyso-GL1 (p = .027), NLR (p = .023) and SSI (p = .032). Thus, ALN is a prevalent GD morbidity with wide clinical-spectrum ranging from asymptomatic cases to intestinal obstruction. ALN is related to SSI, NLR and Lyso-GL1 in children with GD.HighlightsChildren with GD had significantly higher NLR and lower PLR compared to controls.Children with GD having ALN had significantly higher SSI, Lyso-GL1 and NLR than those without ALN.ALN was independently related to Lyso-GL1, NLR and SSI in children with GD.

RESUMO

OBJECTIVE: To update French oncology guidelines concerning penile cancer. METHODS: Comprehensive Medline search between 2020 and 2022 upon diagnosis, treatment and follow-up of testicular germ cell cancer to update previous guidelines. Level of evidence was evaluated according to AGREE-II. RESULTS: Epidermoid carcinoma is the most common penile cancer histology. Physical examination is mandatory to define local and inguinal nodal cancer stage. MRI with artificial erection can help to assess deep infiltration in cases of organsparing intention. Node negative patients (defined by palpation and imaging) will present micro nodal metastases in up to 25% of cases. Invasive lymph node assessment is thus advocated except for low risk patients. Sentinel node dynamic biopsy is the first line technique. Modified bilateral inguinal lymphadenectomy is an option with higher morbidity. 18-FDG-PET is recommended in patients with palpable nodes. Chest, abdominal and pelvis computerized tomography is an option. Fine needle aspiration (when positive) is an easy way to assess inguinal palpable node pathological involvement. Its results determine the type of lymphadenectomy to be performed (for diagnostic or curative purposes). Treatment is mostly surgical. Free margins status is essential, but it also has to be organ-sparing when possible. Brachytherapy and topic agents can cure in selected cases. Lymph node assessment should be synchronous to the removal of the tumour when possible. Limited inguinal lymph node involvement (pN1 stage) can be cured with the only lymphadenectomy. In case of larger lymph node stage, one should consider multidisciplinary treatment including chemotherapy and inclusion in a trial. CONCLUSIONS: Penile cancer needs demanding surgery to be cured, surrounded by chemotherapy in node positive patients. Lymph nodes involvement is a major prognostic factor. Thus, inguinal node assessment cannot be neglected.

RESUMO

Reports of patients with axillary adenopathy identified on breast imaging after coronavirus disease (COVID-19) vaccination are rising. We propose a pragmatic management approach based on clinical presentation, vaccination delivery, and imaging findings. In the settings of screening mammography, screening MRI, and diagnostic imaging workup of breast symptoms, with no imaging findings beyond unilateral axillary adenopathy ipsilateral to recent (within the past 6 weeks) vaccination, we report the adenopathy as benign with no further imaging indicated if no nodes are palpable 6 weeks after the last dose. For patients with palpable axillary adenopathy in the setting of ipsilateral recent vaccination, clinical follow-up of the axilla is recommended. In all these scenarios, axillary ultrasound is recommended if clinical concern persists 6 weeks after vaccination. In patients with a recent breast cancer diagnosis in the pre- or peritreatment setting, prompt recommended imaging is encouraged as well as vaccination (in the thigh or contralateral arm). Our recommendations align with the ACR BI-RADS Atlas and aim to reduce patient anxiety, provider burden, and costs of unnecessary evaluation of enlarged nodes in the setting of recent vaccinations and, also, to avoid further delays in vaccinations and breast cancer screening during the pandemic.

RESUMO

Nontuberculous mycobacterial lymphadenitis often presents a diagnostic challenge. This study aimed to evaluate the role of fine-needle aspiration cytology in the diagnosis of nontuberculous mycobacterial lymphadenitis in children. We conducted a retrospective review of fine-needle aspiration cytology performed in patients < 17 year-old with subacute lymphadenitis from 2003 to 2016 in a tertiary hospital in Spain. Confirmed nontuberculous mycobacterial lymphadenitis (isolation of nontuberculous mycobacterial in culture from fine-needle aspiration cytology or biopsy samples) and probable nontuberculous mycobacterial lymphadenitis ("granulomatous inflammation" in cytopathologic examinations from fine-needle aspiration cytology or biopsy and clinical-epidemiological history compatible with nontuberculous mycobacterial) were selected. Forty-one patients with nontuberculous mycobacterial lymphadenitis were included: 14 confirmed and 27 probable. Fine-needle aspiration cytology was done in all of them. For 34 patients with excised lymphadenopathy, cytopathology from fine-needle aspiration cytology was concordant with biopsy in 100% cases. Culture results were available from 78.0% (32/41) of patients with fine-needle aspiration cytology and from 85.3% (29/34) with excisional biopsy. Among 22 patients with microbiological results from fine-needle aspiration cytology and biopsy, fine-needle aspiration cytology allowed advanced results in concordance with biopsy or with positive isolation not found in biopsy in 90.1% (20/22) of patients. Sensitivity of nontuberculous mycobacterial cultures obtained by fine-needle aspiration cytology compared to biopsy was 45.5% vs. 36.4% (p = 0.07). Two patients with previous skin alterations presented fistulas after fine-needle aspiration cytology (4.9%); no other complications were described.Conclusion: Fine-needle aspiration cytology provides quick cytopathologic information and is an accurate and safe technique for the diagnosis of nontuberculous mycobacterial lymphadenitis, especially in cases with challenging work-up. What is Known: • Nontuberculous mycobacterial (NTM) infection is an important cause of subacute lymphadenitis in children. • Fine-needle aspiration cytology (FNAC) is an available technique for the diagnosis of lymphadenitis of unknown etiology. What is New: • FNAC is an accurate and safe technique for the diagnosis of NTM lymphadenitis in children. • FNAC can provide reliable samples for cytopathological studies and even a better sensitivity for microbiological culture than excisional biopsy in the study of suspected NTM lymphadenitis.

RESUMO

Rationale: When stereotactic ablative radiotherapy is an option for patients with non-small cell lung cancer (NSCLC), distinguishing between N0, N1, and N2 or N3 (N2|3) disease is important.Objectives: To develop a prediction model for estimating the probability of N0, N1, and N2|3 disease.Methods: Consecutive patients with clinical-radiographic stage T1 to T3, N0 to N3, and M0 NSCLC who underwent endobronchial ultrasound-guided staging from a single center were included. Multivariate ordinal logistic regression analysis was used to predict the presence of N0, N1, or N2|3 disease. Temporal validation used consecutive patients from 3 years later at the same center. External validation used three other hospitals.Measurements and Main Results: In the model development cohort (n = 633), younger age, central location, adenocarcinoma, and higher positron emission tomography-computed tomography nodal stage were associated with a higher probability of having advanced nodal disease. Areas under the receiver operating characteristic curve (AUCs) were 0.84 and 0.86 for predicting N1 or higher (vs. N0) disease and N2|3 (vs. N0 or N1) disease, respectively. Model fit was acceptable (Hosmer-Lemeshow, P = 0.960; Brier score, 0.36). In the temporal validation cohort (n = 473), AUCs were 0.86 and 0.88. Model fit was acceptable (Hosmer-Lemeshow, P = 0.172; Brier score, 0.30). In the external validation cohort (n = 722), AUCs were 0.86 and 0.88 but required calibration (Hosmer-Lemeshow, P < 0.001; Brier score, 0.38). Calibration using the general calibration method resulted in acceptable model fit (Hosmer-Lemeshow, P = 0.094; Brier score, 0.34).Conclusions: This prediction model can estimate the probability of N0, N1, and N2|3 disease in patients with NSCLC. The model has the potential to facilitate decision-making in patients with NSCLC when stereotactic ablative radiotherapy is an option.

RESUMO

We present three clinical cases to show the diversity of clinical presentations of Bartonella henselae infection, from classical adenopathy to disseminated form. It is an infection that leads to diagnostic wandering, due to a lack of explicit history and the variety of clinical manifestations. Antibiotic therapy is rarely necessary because it has a spontaneously favourable evolution in the majority of cases.


Nous présentons trois cas permettant de montrer l'hétérogénéité des tableaux cliniques de l'infection à Bartonella henselae, de l'adénopathie classique à la forme disséminée. Il s'agit d'une infection qui peut mener à une errance diagnostique, en raison d'une anamnèse parfois peu parlante et de la diversité des présentations cliniques. L'antibiothérapie est rarement nécessaire puisqu'il s'agit d'une maladie à évolution spontanément favorable dans la majorité des cas.

OBJECTIVE: - To update French oncology guidelines concerning penile cancer. METHODS: - Comprehensive Medline search between 2018 and 2020 upon diagnosis, treatment and follow-up of testicular germ cell cancer to update previous guidelines.

Chest, abdominal and pelvis computerized tomography is an option. Fine needle aspiration (when positive) is an easy way to assess inguinal palpable node pathological involvement. Its results determine the type of lymphadenectomy to be performed (for diagnostic or curative purposes). Treatment is mostly surgical. Free margins status is essential, but it also has to be organ-sparing when possible. Brachytherapy and topic agents can cure in selected cases. Lymph node assessment should be synchronous to the removal of the tumour when possible. Limited inguinal lymph node involvement (pN1 stage) can be cured with the only lymphadenectomy. In case of larger lymph node stage, one should consider multidisciplinary treatment including chemotherapy and inclusion in a trial. CONCLUSIONS: - Penile cancer needs demanding surgery to be cured, surrounded by chemotherapy in node positive patients. Lymph nodes involvement is a major prognostic factor. Thus, inguinal node assessment cannot be neglected.

RESUMO

A 56-year-old previously healthy man presented to the dermatology clinic with a 2-year history of an expanding, violaceous, infiltrated plaque on the right flank. Biopsy revealed a diffuse dermal vascular proliferation of bland, capillary-sized vessels admixed with conspicuous fibrohistiocytic cells including scattered multinucleated floret cells. Further workup revealed a monoclonal gammopathy, an osteolytic chest wall plasmacytoma underlying the plaque, and regional lymphadenopathy leading to a diagnosis of adenopathy and extensive skin patch overlying a plasmacytoma (AESOP). Biopsy of an enlarged lymph node revealed Castleman disease. The patient subsequently developed polyneuropathy and peripheral edema, which supported an additional diagnosis of polyneuropathy, organomegaly, endocrinopathy, monoclonal protein, and skin changes (POEMS) syndrome. Herein, we discuss the unique findings of our patient, the potential pathogenesis of AESOP, and the link between these three rare paraneoplastic entities along with review of the literature.

RESUMO

OBJECTIVES: We sought to identify predictors for a drainable suppurative adenitis [DSA] among patients presenting with acute cervical lymphadenitis. METHODS: A retrospective cross sectional study of all patients admitted to an urban pediatric tertiary care emergency department over a 15 year period. Otherwise healthy patients who underwent imaging for an evaluation of cervical lymphadenitis were included. Cases were identified using a text-search module followed by manual review. We excluded immunocompromised patients and those with lymphadenopathy felt to be not directly infected (i.e. reactive) or that was not acute (symptom duration >28 days). Data collected included: age, gender, duration of symptoms, highest recorded temperature, physical exam findings, laboratory and imaging results, and surgical findings. A DSA was defined as >1.5 cm in diameter on imaging. We performed binary logistic regression to determine independent clinical predictors of a DSA. RESULTS: Three hundred sixty-one patients met inclusion criteria. Three hundred six patients (85%) had a CT scan, 55 (15%) had an ultrasound and 33 (9%) had both. DSA was identified in 71 (20%) patients. Clinical features independently associated with a DSA included absence of clinical pharyngitis, WBC >15,000/mm3, age ≤3 years, anterior cervical chain location, largest palpable diameter on exam >3 cm and prior antibiotic treatment of >24 h. The presence of fever, skin erythema, or fluctuance on examination, was not found to be predictive of DSA. CONCLUSIONS: We identified independent predictors of DSA among children presenting with cervical adenitis. Risk can be stratified into risk groups based on these clinical features.

RESUMO

BACKGROUND: Tularaemia is a zoonotic disease caused by inoculation with the Gram-negative coccobacillus Francisella tularensis. It was first described in the United States in 1911 and is a rare disease with an annual reported incidence in France between 2002 and 2012 of 0.07 cases per 100,000 habitants. Reporting of the disease in humans has been mandatory in France since 2003. PATIENTS AND METHODS: Herein we report a case of tularaemia following a tick bite in a patient in the north of France. DISCUSSION: Tularaemia is a rare form of zoonosis that should be sought in the event of unexplained adenitis. Clinical presentations vary, and in certain cases only dermatological signs are manifest. Diagnosis is confirmed by bacterial serology. Rapid initiation of suitable antibiotics produces a favourable and benign outcome in most cases. However, the offending organism, which is potentially lethal, is classed as a potential bioterrorism agent.

RESUMO

RATIONALE: Estimating the probability of finding N2 or N3 (prN2/3) malignant nodal disease on endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in patients with non-small cell lung cancer (NSCLC) can facilitate the selection of subsequent management strategies. OBJECTIVES: To develop a clinical prediction model for estimating the prN2/3. METHODS: We used the AQuIRE (American College of Chest Physicians Quality Improvement Registry, Evaluation, and Education) registry to identify patients with NSCLC with clinical radiographic stage T1-3, N0-3, M0 disease that had EBUS-TBNA for staging. The dependent variable was the presence of N2 or N3 disease (vs. N0 or N1) as assessed by EBUS-TBNA. Univariate followed by multivariable logistic regression analysis was used to develop a parsimonious clinical prediction model to estimate prN2/3. External validation was performed using data from three other hospitals. MEASUREMENTS AND MAIN RESULTS: The model derivation cohort (n = 633) had a 25% prevalence of malignant N2 or N3 disease. Younger age, central location, adenocarcinoma histology, and higher positron emission tomography-computed tomography N stage were associated with a higher prN2/3. Area under the receiver operating characteristic curve was 0.85 (95% confidence interval, 0.82-0.89), model fit was acceptable (Hosmer-Lemeshow, P = 0.62; Brier score, 0.125). We externally validated the model in 722 patients. Area under the receiver operating characteristic curve was 0.88 (95% confidence interval, 0.85-0.90). Calibration using the general calibration model method resulted in acceptable goodness of fit (Hosmer-Lemeshow test, P = 0.54; Brier score, 0.132). CONCLUSIONS: Our prediction rule can be used to estimate prN2/3 in patients with NSCLC. The model has the potential to facilitate clinical decision making in the staging of NSCLC.
