[Anti-IL-5 in severe asthma associated with eosinophilic granulomatosis with polyangiitis. Real-life study]. / Anti-IL-5 dans l'asthme sévère associé à une granulomatose éosinophilique avec polyangéite. Étude en vie réelle.

INTRODUCTION: Eosinophilic granulomatosis with polyangiitis (EGPA) is a form of necrotizing vasculitis affecting small vessels and typically characterized by severe glucocorticoid (GC)-dependent eosinophilic asthma. While mepolizumab, which is indicated at a dose of 100mg/4weeks in severe eosinophilic asthma, has been shown to be an effective treatment for EGPA-related asthma at a dose of 300mg/4weeks, it was only recently approved at this dose. METHODS: This retrospective, single-center, observational study was conducted to investigate over a 5-year period (2014-2019) the effect of mepolizumab 100mg/4weeks at 12months in patients with EGPA and glucocorticoid-dependant severe asthma. Response to treatment was defined as reduction in daily dose of oral corticosteroids to at most 5mg/day or reduction in annual exacerbation by at least 50%. RESULTS: Thirty patients were included, of whom twenty-three were treated (two were not fully evaluable). Among the 21 evaluable treated patients, 13 (62%) had responded at 12months. At baseline, non-responders had lower FEV1 levels and lower blood eosinophil levels than responders. CONCLUSIONS: Mepolizumab at a "severe asthma" dose (100mg/4weeks) is effective in treatment of GC-dependent severe asthma in most patients with EGPA.

GCIG-Consensus guideline for Long-term survivorship in gynecologic Cancer: A position paper from the gynecologic cancer Intergroup (GCIG) symptom benefit committee.

INTRODUCTION: Long-term survivors of gynecological cancers may be cured but still have ongoing health concerns and long-term side effects following cancer treatment. The aim of this brainstorming meeting was to develop recommendations for long-term follow-up for survivors from gynecologic cancer. METHODS: International experts, representing each member group within the Gynecologic Cancer InterGroup (GCIG), met to define long-term survival, propose guidelines for long term follow-up and propose ways to implement long term survivorship follow-up in clinical trials involving gynecological cancers. RESULTS: Long-term survival with/from gynecological cancers was defined as survival of at least five years from diagnosis, irrespective of disease recurrences. Review of the literature showed that more than 50% of cancer survivors with gynecological cancer still experienced health concerns/long-term side effects. Main side effects included neurologic symptoms, sleep disturbance, fatigue, sexual dysfunction, bowel and urinary problems and lymphedema. In this article, long-term side effects are discussed in detail and treatment options are proposed. Screening for second primary cancers and lifestyle counselling (nutrition, physical activity, mental health) may improve quality of life and overall health status, as well as prevent cardiovascular events. Clinical trials should address cancer survivorship and report patient reported outcome measures (PROMs) for cancer survivors. CONCLUSION: Long-term survivors after gynecological cancer have unique longer term challenges that need to be addressed systematically by care givers. Follow-up after completing treatment for primary gynecological cancer should be offered lifelong. Survivorship care plans may help to summarize cancer history, long-term side effects and to give information on health promotion and prevention.

Light chain deposition disease presenting as an atrial mass: a case report and review of literature.

Light chain deposition disease (LCDD) also known as nonamyloidotic immunoglobulin deposition disease is a rare systemic disorder due to the abnormal deposition of immunoglobulin in multiple organs caused by the clonal proliferation of B lymphocytes and plasma cells. Renal involvement is the most common with cardiac manifestations being the most common extra renal presentation of the disease. Renal involvement is not always associated with LCDD. Isolated cardiac involvement can manifest in a wide variety of ways: heart failure, cardiomyopathy, arrhythmias, angina, myocardial infarction, etc. We hereby present an unusual case of 59-year-old female who presented to clinic for routine follow up. A murmur on physical exam was evaluated with echocardiogram which led to the discovery of an incidental right atrial mass. Cardiac magnetic resonance imaging was completed 6 months later for follow up which showed increasing size of the mass. The mass was excised and found to be consistent with LCDD. To the best of our knowledge, this is the first reported case of LCDD manifesting as an atrial mass. Through this case report and review of literature we would like to generate awareness among our fellow pathologists and clinicians to maintain a high level of suspicion for LCDD as it can manifest in many unusual ways, with or without kidney involvement.

Association between pelvic inflammatory disease, infertility, ectopic pregnancy and the development of ovarian serous borderline tumor, mucinous borderline tumor and low-grade serous carcinoma.

OBJECTIVE: Risk factors for ovarian borderline tumors and low-grade serous carcinoma (LGSC) are poorly understood. The aim of this study was to examine the association between infertility, pelvic inflammatory disease (PID), endometriosis, ectopic pregnancy, hysterectomy, tubal ligation and parity and the risk of serous borderline tumor (SBT), mucinous borderline tumor (MBT) and LGSC. METHODS: This was a population-based cohort study using linked administrative and hospital data. Participants were 441,382 women born between 1945 and 1975 who had been admitted to hospital in Western Australia between 1 January 1980 and 30 June 2014. We used Cox regression to estimate hazard ratios (HRs). RESULTS: We observed an increased rate of SBT associated with infertility, PID and ectopic pregnancy (HRs and 95% CIs were, respectively, 1.98 (1.20-3.26); 1.95 (1.22-3.10) and 2.44 (1.20-4.96)). We did not detect an association between any of the factors under study and the rate of MBT. A diagnosis of PID was associated with an increased rate of LGSC (HR 2.90, 95% CI 1.21-6.94). CONCLUSIONS: The association with PID supports the hypothesis that inflammatory processes within the upper gynaecological tract and/or peritoneum may predispose to the development of SBT and LGSC.

Advanced basal cell cancer: concise review of molecular characteristics and novel targeted and immune therapeutics.

Metastatic basal cell carcinoma is an ultra-rare manifestation of a common disease, appearing in 0.0028%-0.5% of basal cell carcinomas. Initial therapeutic efforts focused on cytotoxic chemotherapy administration. However, it is now known that the Hedgehog signaling pathway is crucial for basal cell proliferation and Hedgehog pathway mutations may lead to tumorigenesis; thus, small-molecule inhibitors of alterations in the components of this pathway, including smoothened (SMO) and GLI, have been the focus of recent therapeutic developments. Indeed, the European Medicines Agency and the Food and Drug Administration have approved the SMO inhibitors, vismodegib and sonidegib, with additional GLI inhibitors currently in clinical trials. Molecular profiling of these tumors has revealed other potential targets for therapy, including high tumor mutational burden and PD-L1 amplification, which predict response to immune checkpoint blockade (PD-1 and PD-L1 inhibitors). An illustrative patient with a giant, advanced, unresectable basal cell carcinoma who obtained an ongoing complete remission after treatment with a combination of an immune checkpoint inhibitor (due to the tumor's high mutational burden) and the Hedgehog inhibitor vismodegib is described. A fuller understanding of the genomic portfolio of these patients can assist in developing novel, rational therapeutic approaches that should continue to improve responses and outcomes.

Survival times in dogs with presumptive intracranial gliomas treated with oral lomustine: A comparative retrospective study (2008-2017).

Intracranial gliomas are a common malignancy in dogs, and are associated with a poor prognosis due to their aggressive nature and a lack of clinically effective treatments. The efficacies of various treatment modalities for canine brain tumours have been previously described, though little data exist on the use of cytotoxic chemotherapy. A comparative retrospective study, including 40 cases from 5 northeastern US veterinary hospitals, from 2008 to 2017, was conducted. Variables analysed in this study with relation to overall survival and prognostic significance included: age, sex, clinical signs, clinical sign duration, tumour location and treatment protocol used. Dogs with presumptive intracranial gliomas treated with lomustine chemotherapy lived longer (median, 138 days) than those treated exclusively with symptomatic care (median, 35 days; P = .0026 log-rank, 0.0138 Wilcoxon). Additionally, a duration of clinical signs ≥16 days prior to diagnosis (median, 109 days) was associated with a longer survival than a duration <16 days prior (median, 25 days; P = .0100 log-rank, 0.0322 Wilcoxon). Lomustine-associated side effects included neutropenia in 46% of dogs, anaemia in 15% and thrombocytopenia in 15%. Potential renal and hepatotoxicity based on increased BUN and/or creatinine and ALT values were reported in 15% and 50% of dogs, respectively. This study provides evidence that lomustine therapy may be effective in prolonging survival in dogs with intracranial gliomas and should be considered as a potential treatment option. Although lomustine-related toxicities are fairly common, they are rarely life threatening and often do not result in discontinuation of therapy.

Risk of persistent or recurrent cervical neoplasia in patients with 'pure' adenocarcinoma-in-situ (AIS) or mixed AIS and high-grade cervical squamous neoplasia (cervical intra-epithelial neoplasia grades 2 and 3 (CIN 2/3)): a population-based study.

OBJECTIVE: To compare outcomes of patients with pure adenocarcinoma-in-situ (AIS) and mixed AIS/CIN 2/3 lesions including the incidence of AIS persistence, recurrence and progression to adenocarcinoma. DESIGN: Retrospective cohort study. SETTING: Statewide population in Western Australia. POPULATION: Women diagnosed with AIS between 2001 and 2012. METHODS: We conducted a retrospective, population-based cohort study. MAIN OUTCOME MEASURES: De-identified linked data were utilised to ascertain the association between patient age at excisional treatment, margin status, lesion type, lesion size, and risk of persistent AIS (defined as the presence of AIS <12 months from treatment), recurrent AIS (≥12 months post-treatment), and adenocarcinoma. RESULTS: 636 patients were eligible for analysis. The mean age was 32.3 years and median follow-up interval was 2.5 years. Within the study cohort, 266 patients (41.8%) had pure AIS and 370 (58.2%) had mixed AIS/CIN 2/3. Overall, 47 patients (7.4%) had AIS persistence/recurrence and 12 (1.9%) had adenocarcinoma. Factors associated with persistence/recurrence were pure AIS (hazard ratio (HR) 2.3; 95%CI 1.28-3.94; P = 0.005), age >30 years (HR 2.1; 95%CI 1.16-3.81; P = 0.015), positive endocervical margins (HR 5.8; 95%CI 3.05-10.92; P = <0.001) and AIS lesions >8 mm (HR 2.5; 95%CI 1.00-6.20; P = 0.049). A histologically positive AIS ectocervical margin was not associated with persistence/recurrence. CONCLUSION: In this study, pure AIS was associated with greater risk of persistence/recurrence than was mixed AIS/CIN 2/3. AIS lesions >8 mm and positive endocervical margins were significant predictors for persistent or recurrent disease. TWEETABLE ABSTRACT: Pure cervical adenocarcinoma-in-situ (AIS) may have greater risk of recurrence than AIS co-existing with CIN 2/3.

Enoxaparin dosing errors in the emergency department / 世界急诊医学杂志（英文）

BACKGROUND:The study aimed to determine the frequency of enoxaparin dosing errors for patients who had a measured emergency department (ED) weight compared to those who did not have a measured ED weight, and to determine if demographic variables (e.g., weight, height, age, English-speaking, race) impact the likelihood of receiving an inappropriate dose. METHODS:This is a retrospective, electronic chart review of patients who received a dose of enoxaparin in the ED between January 1, 2008 and July 1, 2013. We identified all patients >18 years who received a dose of enoxaparin while in the ED, were admitted, and had at least one inpatient weight within the first four days of hospitalization. Patients were excluded if they received enoxaparin for prophylaxis or a dose of more than 1.25 mg/kg. RESULTS:A total of 1,944 patients were included. Patients were more likely to experience an error if they did not have a measured ED weight. Over-doses of >10 mg were more likely to occur in patients without a measured ED weight. Patients with no documented ED weight or with a staff-estimated ED weight were more likely to experience a dosing error than those with a patient-stated weight. Patients were more likely to experience an error if their first inpatient weight was more than 96 kg, they were more than 175-cm tall, or were English speaking. CONCLUSION:Dosing errors are more likely to occur when patients are not weighed in the ED. Modifications to current workflows to incorporate weighing those patients who receive weight-dosed medications may be warranted.

Oncological outcomes in an Australian cohort according to the new prostate cancer grading groupings.

BACKGROUND: A new 5-tiered grading grouping system has recently been endorsed for reporting of prostate cancer (PCa) grade to better reflect escalating risk of progression and cancer death. While several validations of the new grade groupings have been undertaken, most have involved centralised pathological review by specialist urological pathologists. METHODS: Participants included 4268 men with non-metastatic PCa diagnosed between 2006 and 2013 from the multi-institutional South Australia Prostate Cancer Clinical Outcomes Collaborative registry. PCa-specific survival and biochemical recurrence-free survival were compared across the five grade groups using multivariable competing risk regression. RESULTS: For the entire cohort, risk of PCa death increased with increasing grade groups (at biopsy) Adjusted subdistribution-hazard ratios [sHR] and 95% confidence intervals [95%CI] were: 2.2 (1.5-3.6); 2.5 (1.6-4.2); 4.1 (2.6-6.7) and 8.7 (4.5-14.0) for grade groups II (pattern 3 + 4), III (pattern 4 + 3), IV (total score 8) and V (total score 9-10) respectively, relative to grade group I (total score < =6). Clear gradients in risk of PCa death were observed for radical prostatectomy (RP), but were less clear for those who had radiotherapy (RT) with curative intent and those who were managed conservatively. Likewise, risk of biochemical recurrence increased across grade groups, with a strong and clear gradient for men undergoing RP [sHR (95%CI): 2.0 (1.4-2.8); 3.8 (2.9-5.9); 5.3 (3.5-8.0); 11.2 (6.5-19.2) for grade groups II, III, IV and V respectively, relative to grade group I], and a less clear gradient for men undergoing RT. CONCLUSION: In general, the new five-tiered grade groupings distinguished PCa survival and recurrence outcomes for men with PCa. The absence of a clear gradient for RT may be due to heterogeneity in this patient group.

Humanin: Functional Interfaces with IGF-I.

Humanin is the first newly discovered peptide encoded in the mitochondrial genome in over three decades. It is the first member of a novel class of mitochondrial derived peptides. This small, 24 amino acid peptide was initially discovered to have neuroprotective effects and subsequent experiments have shown that it is beneficial in a diverse number of disease models including stroke, cardiovascular disease, and cancer. Over a decade ago, our lab found that humanin bound IGFBP-3 and more recent studies have found it to decrease circulating IGF-I levels. In turn, IGF-I also seems to regulate humanin levels and in this review, we cover the known interaction between humanin and IGF-I. Although the exact mechanism for how humanin and IGF-I regulate each other still needs to be elucidated, it is clear that humanin is a new player in IGF-I signaling.

GH safety workshop position paper: a critical appraisal of recombinant human GH therapy in children and adults.

Recombinant human GH (rhGH) has been in use for 30 years, and over that time its safety and efficacy in children and adults has been subject to considerable scrutiny. In 2001, a statement from the GH Research Society (GRS) concluded that 'for approved indications, GH is safe'; however, the statement highlighted a number of areas for on-going surveillance of long-term safety, including cancer risk, impact on glucose homeostasis, and use of high dose pharmacological rhGH treatment. Over the intervening years, there have been a number of publications addressing the safety of rhGH with regard to mortality, cancer and cardiovascular risk, and the need for long-term surveillance of the increasing number of adults who were treated with rhGH in childhood. Against this backdrop of interest in safety, the European Society of Paediatric Endocrinology (ESPE), the GRS, and the Pediatric Endocrine Society (PES) convened a meeting to reappraise the safety of rhGH. The ouput of the meeting is a concise position statement.

A novel surgical technique for the large ovarian cystic mass - combined mini-laparotomy and laparoscopy.

BACKGROUND: Laparoscopic resection of ovarian cysts > ten cm in diameter can be technically challenging. Laparotomy is often the preferred surgical approach. Minimal access surgery in gynaecology has been compared to laparotomy and has been shown to result in shorter patient hospital length of stay, reduced post-operative pain, and faster return to routine activities. Minimal access surgical techniques for ovarian masses > ten cm are therefore of interest as they may offer significant benefits. OBJECTIVE: To assess the feasibility of a novel surgical technique using a combination of both laparoscopy and mini-laparotomy in the surgical management of ovarian cystic masses > ten cm. Outcomes including hospital length of stay, return to usual activities, post-operative complications, and patient satisfaction were assessed. MATERIALS AND METHODS: A total of 17 patients who underwent surgery by a gynaecologic oncologist at a tertiary institution in Western Australia from June 2012 to September 2013 were selected. The risk of malignancy index was used to triage patients. A mini-laparotomy incision was utilised to downsize the mass and to retrieve the specimen, while the remainder of the procedure was performed by laparoscopy. Medical records were used to collect post-operative and follow up data. Patient satisfaction at six weeks post-surgery was analysed by means of a telephone questionnaire. RESULTS: Patients had an average age of 52 years. They were more likely to be post-menopausal and to have a raised body mass index (BMI) (average BMI 29.6 kg/m2). All 17 patients had an ovarian mass larger than ten cm in maximal diameter. Fourteen of the 17 cases were benign. Three patients were diagnosed with early stage mucinous ovarian tumours of low malignant potential. There were no malignancies. The procedure was associated with a high level of patient satisfaction. CONCLUSION: Combined mini-laparotomy and laparoscopy to resect ovarian masses > ten cm has potential benefits for patients in terms of faster recovery, lower analgesia requirements, and improved cosmetic outcome. Larger prospective studies are required to adequately assess complication rates, quality of life, and long-term outcomes in those patients with ovarian tumours of low malignant potential.

Novel BRAF and KRAS Mutations in Papillary Thyroid Carcinoma Arising in Struma Ovarii.

Papillary carcinomas of thyroid type rarely arise within struma ovarii. There are limited data on the immunohistochemical and molecular features of these tumors. Three cases of papillary carcinoma arising in struma ovarii (PCSO) were identified. The clinicopathological features were reviewed and immunohistochemical staining for HBME-1, cytokeratin (CK) 19, and CD56 was performed. Tumor DNA was sequenced for somatic mutations using a panel of 26 oncogenes, with a particular focus on BRAF and KRAS mutations. The patients were aged 22, 48, and 55 years. All cases were FIGO stage IA. Two tumors were of classical histological type, and one was a follicular variant papillary carcinoma. All tumors expressed HBME-1 and two were positive for CK19. CD56 was negative in all three cases. One tumor demonstrated a BRAF G469A mutation in exon 11, and in a second case, a KRAS Q61K double base mutation in exon 3 was detected. These mutations have not been described previously in PCSO. No mutations were detected in the benign follicular components of the tumors adjacent to the malignant papillary tissue. None of the patients had tumor recurrence on clinical follow-up (range 11 months to 8½ years). HBME-1, CK19, and CD56 are useful immunohistochemical markers of PCSO. Novel BRAF and KRAS mutations were identified in two of three tumors suggesting that mutations in PCSO may differ from those commonly identified in papillary carcinoma of the eutopic thyroid. The clinical significance of these mutations is uncertain but follow-up data in this small series support the generally good prognosis of PCSO.

Acute mitral valve regurgitation after acute coronary syndrome.

This article describes acute mitral valve regurgitation as a complication of myocardial infarction in a 66-year-old man presenting to the ED.

Tobacco differentially affects the clinical-biological phenotypes of ANCA-associated vasculitides.

OBJECTIVES: To describe the clinical-biological phenotype of ANCA-associated vasculitides (AAV) according to tobacco consumption. METHODS: We conducted a descriptive study to describe that phenotype at diagnosis according to tobacco use. AAV patients entered in the French Vasculitis Study Group database with data on smoking habits were analysed. The clinical-biological phenotypes at diagnosis were compared according to current tobacco use (current smokers) or not (including previous and never smokers). RESULTS: AAV diagnoses were: granulomatosis with polyangiitis (GPA) for 583 (50%), eosinophilic granulomatosis with polyangiitis (EGPA) for 326 (28%) and microscopic polyangiitis (MPA) for 256 (22%). Among them, 973 patients (84%) never smoked, 116 (10%) were previous smokers and only 76 (6%) were current smokers. Current smokers were younger age (p=0.01), male gender (p=0.004), less frequently EGPA (p=0.017) and MPA (p=0.036), and had less frequent kidney involvement (p=0.10). Among GPA patients, current smokers, compared to non-current smokers, were younger age (p=0.02), male gender (p=0.08), more frequent skin involvement (p=0.03) and less frequent ENT involvement (p=0.06). Among EGPA patients, current smokers, compared to non-current smokers, were also younger (p=0.028) and had less frequent constitutional symptoms (p=0.02), arthralgias (p=0.04), renal involvement (p=0.025) and MPO-ANCA (p=0.02). Finally, analysis of MPA patients was impossible because only 6 (2%) were current smokers. CONCLUSIONS: These results suggest that tobacco use could differentially affect GPA and EGPA clinical-biological phenotypes, and support the role of environmental exposures in AAV development and its phenotype.

Comparison of cold knife cone biopsy and loop electrosurgical excision procedure in the management of cervical adenocarcinoma in situ: What is the gold standard?

OBJECTIVE: To compare the outcomes of patients with cervical adenocarcinoma in situ (ACIS) treated with cold knife cone (CKC) biopsy or loop electrosurgical excision procedure (LEEP) for the treatment of cervical adenocarcinoma in situ (ACIS). STUDY DESIGN: This is a retrospective, population-based cohort study of Western Australian patients with ACIS diagnosed between 2001 and 2012. Outcomes included pathological margin status and the incidence of persistent or recurrent endocervical neoplasia (ACIS and adenocarcinoma) during follow-up (<12 months) and surveillance (≥12 months) periods. RESULTS: The study group comprised 338 patients including 107 (32%) treated initially by LEEP and 231 (68%) treated by CKC biopsy. The mean age was 33.2 years (range 18 to 76 years) and median follow-up interval was 3.6 years (range <1 year to 11.8 years). Overall, 27 (8.0%) patients had ACIS persistence/recurrence while 9 (2.7%) were diagnosed with adenocarcinoma during the follow-up and surveillance periods. No patient died of cervical cancer within the study period. There were no significant differences in the incidence of persistent and/or recurrent endocervical neoplasia according to the type of excisional procedure. Patients with positive biopsy margins were 3.4 times more likely to have disease persistence or recurrence. CONCLUSION(S): LEEP and CKC biopsy appear equally effective in the treatment of ACIS for women wishing to preserve fertility. Patients undergoing conservative management for ACIS should be closely monitored, particularly if biopsy margins are positive in initial excision specimens. Patients and their clinicians should be aware of the potential risks of residual and recurrent disease.
