Organizing pneumonia following Covid19 pneumonia.

The potential mid-term and long-term consequences after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections are as yet unknown. This is the first report of bronchoscopically verified organizing pneumonia as a complication of coronavirus disease 2019 (Covid19). It caused persisting dyspnea, impaired pulmonary function, and radiological abnormalities over 5 weeks after onset of symptoms. While organizing pneumonia frequently requires treatment with systemic corticosteroids, in this case it resolved spontaneously without treatment after 6 weeks. Healthcare professionals should consider organizing pneumonia in patients with persisting respiratory symptoms after Covid19.

Bone Scintigraphy in Staging of Newly Diagnosed Prostate Cancer in Regard of Different Risk Groups.

OBJECTIVES: Prostate cancer (PC) is the most common cancer in men over 50 years of age. Bone scintigraphy is still performed in many institutions at the time of primary diagnosis. We aimed to evaluate the role of bone scan in the primary staging of PC in regard of different risk groups. METHODS: A retrospective analysis of bone scans in 296 patients (mean age 64±6 y) acquired at the time of primary diagnosis was performed in our institution. The median prostate specific antigen (PSA) was 6.73 ng/ml, all patients had a Gleason score of >5. RESULTS: Only 11/296 patients had a positive bone scan, 1 being in the intermediate risk group, 10 in the high-risk group and none in the low-risk group according to D'Amico classification. CONCLUSION: Our results support the few published studies that less than 10% of patients with newly diagnosed PC by biopsy would develop bone metastasis, all in the intermediate or high-risk groups. Therefore, a staging by bone scan can only be recommended in patients with intermediate or high-risk, or symptomatic patients only.

Joint Guideline of the OEGGG, AGO, AGK and ÖGZ on the Diagnosis and Treatment of Cervical Intraepithelial Neoplasia and Appropriate Procedures When Cytological Specimens Are Unsatisfactory.

Purpose On January 1st, 2018, the ÖGZ (Austrian Society of Cytology) revised its cytological nomenclature to make it more similar to the 2015 Bethesda system. Following these changes, the Austrian Society of Gynecology and Obstetrics felt it necessary to revise the approach currently used in Austria to diagnose and treat CIN and to review the procedures to be followed when the quality of cytological specimens is unsatisfactory. It was not possible to adopt the German S3 guideline "Prevention of Cervical Cancer" in its entirety, because the Munich III gynecological cytology nomenclature used in Germany is not used in Austria. This made it necessary to compile a separate scientific opinion for Austria. Methodology The OEGGG worked together with the ÖGZ (Austrian Society for Cytology), AGO Austria (Austrian Working Group for Gynecological Oncology), the AGK (Colposcopy Working Group), and physicians representing gynecologists in private practice. The different scientific associations nominated representatives, who attended the various meetings. After an in-depth analysis of the recent literature, three meetings and numerous votes by telephone, we were able to achieve a consensus about the contents of this guideline. Recommendations The guideline provides recommendations for the diagnosis and treatment of CIN which take account of the gynecological cytology nomenclature used in Austria.

Oncocytic adenomas of thyroid-mimicking benign or metastatic disease on 18F-FDG-PET scan.

BACKGROUND: The literature is sparse concerning 18F-fluorodeoxyglucose (18F-FDG) accumulation in the Hürthle cell neoplasm (HCN) of the thyroid. Given the difficulty of accurately diagnosing HCN, even with ultrasound (US) and fine needle aspiration biopsy (FNAB), the ability to accurately characterize these lesions by 18F-FDG positron emission tomography (PET) would be of value. PURPOSE: To describe six cases of oncocytic proliferation in the thyroid gland that mimics the presence of metastatic disease and was detected incidentally by an 18F-FDG PET scan. MATERIAL AND METHODS: We conducted whole-body 18F-FDG PET examinations for cancer staging in 1862 oncological patients from 2012 to 2013. Among them, six subjects (4 women, 2 men; age range, 45-85 years) with focal-enhanced 18F-FDG accumulation in the thyroid gland were selected from the study population. This study group was further investigated using 99 m-Tc-pertechnetate scintigraphy, US, and FNAB. Two experienced nuclear physicians reviewed the images. Gray-scale US and color Doppler (CD) sonographic examinations of the thyroid were undertaken for all subjects using a sonographic device Logiq 5 Expert (GE Medical Systems, Osaka, Japan) equipped with a 7-12 MHz linear array transducer. RESULTS: In all six cases, abnormal 18F-FDG uptake was found locally in the thyroid. The average SUVmax of the HCN was 5.8 (range, 2.6-16). In all six cases, 99 m-Tc-pertechnetate scintigraphy showed a cold spot. Compared with normal parenchymal vascularity, five of the six masses were shown to be hypervascular by CD ultrasonography. CONCLUSION: On PET scans, oncocytic proliferations of the thyroid may mimic metastases of other malignancies. The focal-enhanced uptake of 18F-FDG PET may be associated with a focal increase in the metabolic activity of the thyroid parenchyma due to the presence of oncocytes. Our study emphasizes the importance of obtaining cytological evidence before making a diagnosis of metastatic disease.

Investigation of 208 consecutive cases of cervical cone biopsies with regard to indication, negative samples and quality control.

OBJECTIVE: To analyze factors in preoperative management and cytologic screening leading to a conization specimen free of neoplasia. STUDY DESIGN: From January 2001 through December 2003, cervical conization was performed on 208 consecutive cases at the Gynecologic Department, Krankenhaus Lainz, Vienna. Indications for cone biopsy were based on suspicious internal and/or external conventional cytologic screening results followed by punch biopsies in selected cases. RESULTS: Benign cervical lesions were diagnosed in 22 women (10.6%). Histologic results in negative cone biopsies were cervicitis (n = 12), infection with HPV without cervical intraepithelial neoplasia (n = 1), tubal metaplasia (n = 4) and combined diagnoses indicating no neoplasia (n = 5). Regarding cytologic screening results prior to conization, long-lasting infections with HPV can cause repeated findings of cells of unknown origin or reversible mild to moderate dysplasia eventually leading to conization specimens free of neoplasia. Furthermore, tubal metaplasia is a frequent pitfall in misinterpretation of cytologic smears. CONCLUSION: Reevaluation of cytologic screening results after the final histologic diagnosis becomes available following cone biopsy is a key issue in continuous quality assurance for the diagnostic procedure. In this article we also present a method of stratifying screening results according to the correctness of the results. Along with other established measures of diagnostic performance, this may support benchmarking and interpretation of the overall cytologic screening quality.

Impact of haemoglobin levels during adjuvant chemotherapy on the survival of patients with primary breast cancer.

Tumour anaemia is a common symptom in cancer patients, particularly in those receiving chemotherapy. The aim of the current study was to analyse the impact of haemoglobin levels on the prognosis of patients with primary breast cancer receiving adjuvant chemotherapy. A total of 129 patients were available for analysis. The estimated median five-year overall survival rate was 76.6%. Mean Hb prior to primary surgery was 13.8 g/dl (SD 1.09), pre-chemotherapy Hb 12.8 g/dl (SD 1.2), and nadir Hb during chemotherapy 11.0 g/dl (SD1.1), respectively. Hb values were analysed as continuous variables in the Cox model. Survival analyses did not show a correlation between preoperative and pre-chemotherapy Hb levels with patient outcome. However, univariate analysis identified low nadir Hb (p=0.008), larger tumours (p=0.042), and hormone-receptor-negative tumours (p=0.022) to be significantly associated with poor patient survival. This result was persistent when analysis was adjusted for relevant prognostic factors in a multivariate Cox proportional hazards model. Nadir Hb, 1.54-fold increased risk for death (95% CI 1.03-2.32), and tumour size, 3.2-fold increased risk (95% CI 1.17-8.77) remained as independent variables, whereas hormone-receptor status failed to retain significance. The present data showed anaemia during adjuvant chemotherapy to be associated with poor survival in patients with primary breast cancer. Prospective randomized trials are warranted to examine the value of correcting anaemia with regard to improve disease control and survival.
