Abstract
OBJECTIVE Previous studies have unveiled a relationship between the severity of coronavirus disease 2019 (COVID-19) pneumonia and obesity. The aims of this multicenter retrospective cohort study were to disentangle the association of BMI and associated metabolic risk factors (diabetes, hypertension, hyperlipidemia, and current smoking status) in critically ill patients with COVID-19. METHODS Patients admitted to intensive care units for COVID-19 in 21 centers (in Europe, Israel, and the United States) were enrolled in this study between February 19, 2020, and May 19, 2020. Primary and secondary outcomes were the need for invasive mechanical ventilation (IMV) and 28-day mortality, respectively. RESULTS A total of 1,461 patients were enrolled; the median (interquartile range) age was 64 years (40.9-72.0); 73.2% of patients were male; the median BMI was 28.1 kg/m2 (25.4-32.3); a total of 1,080 patients (73.9%) required IMV; and the 28-day mortality estimate was 36.1% (95% CI: 33.0-39.5). An adjusted mixed logistic regression model showed a significant linear relationship between BMI and IMV: odds ratio = 1.27 (95% CI: 1.12-1.45) per 5 kg/m2 . An adjusted Cox proportional hazards regression model showed a significant association between BMI and mortality, which was increased only in obesity class III (≥40; hazard ratio = 1.68 [95% CI: 1.06-2.64]). CONCLUSIONS In critically ill COVID-19 patients, a linear association between BMI and the need for IMV, independent of other metabolic risk factors, and a nonlinear association between BMI and mortality risk were observed.

Abstract
Left ventricular non-compaction/hypertrabeculation (LVHT) is a rare cardiac abnormality characterized by more than three trabeculations protruding from the left ventricular wall, apically to the papillary muscles, visible in one echocardiographic image plane and intertrabecular spaces, perfused from the ventricular cavity. LVHT is frequently associated with neuromuscular disorders. Differential diagnoses of LVHT are intraventricular thrombi, false tendons, aberrant bands, intramyocardial hematoma, cardiac metastases and the apical type of hypertrophic cardiomyopathy. Intramyocardial abscesses have not been reported as a differential diagnosis of left ventricular non-compaction. In the presented case, cardiac microabscesses as a result of Candida sepsis mimicked left ventricular non-compaction in a 55-year-old man with hypopharyngeal carcinoma who died 20 days after chemotherapy. These microabscesses were not visible on echocardiography but were detected only at histologic examination of the myocardium. This case shows that intramyocardial abscesses as a result of Candida sepsis are a rare differential diagnosis of LVHT.

Abstract
Left ventricular (LV) noncompaction is a rare abnormality characterized by more than three trabeculations protruding from the LV wall, distal to the papillary muscles and visible in one echocardiographic image plane. The intertrabecular spaces are perfused from the LV cavity, as visualized on color Doppler imaging. Differential diagnoses of LV noncompaction are intraventricular thrombi, false tendons, aberrant bands, intramyocardial hematoma, cardiac metastases and the apical type of hypertrophic cardiomyopathy. Intramyocardial abscesses have not been reported as a differential diagnosis of LV noncompaction. In the patient presented, cardiac microabscesses due to candida sepsis mimicked LV noncompaction and should be considered in the differential diagnosis of LV noncompaction.

Abstract
Although rare, sarcoma botryoides of the vagina in infants is a highly aggressive soft tissue tumour. Former opinions suggesting exenterative surgery and radiation to improve the dismal outcome in these young children, are outdated. Due to balanced therapies (topical tumourectomy, chemotherapy and radiation adjusted to tumour stage) cure of these sarcomas may be expected dependent on tumour stage, localisation and response to chemotherapy. The rate of complete remissions has increased in recent years. We report on an eighteen-month old girl with complete remission of tumour stage IIA who had been treated according to the CWS 91 protocol. Diagnosis and treatment were performed in March 1994 at the age of six months. We observed the patient in complete remission for 8 months (till September 1995).

Abstract
The immunophenotype of 6 cases of Langerhans cell histiocytosis (LCH) of the hypothalamus and 3 cases of cranial bone manifestation of LCH was investigated by means of immunohistochemistry on paraffin sections. Antibodies against S 100 protein, lysozyme, CD68 (PG-M1), CD68 (KP1), HLA-DR, beta 2 microglobulin, placental alkaline phosphatase (PLAP), the monoclonal antibody MAC 387, and a monoclonal antibody against CD1a were used. All examined cases showed positive staining of lesional cells for S 100 protein, HLA-DR, beta 2 microglobulin, macrophage associated markers and CD1a. According to the "confidence levels" of the Writing Group of the Histiocyte Society [Chu et al. 1987], a "definite diagnosis" of LCH requires the demonstration either of Birbeck granules in lesional cells by electron microscopy, or of CD1a antigenic determinants on the surface of lesional cells. Since electron microscopy of these rare CNS lesions is not possible in many cases, we are now able to give a definite diagnosis of LCH of the hypothalamus by means of immunohistochemistry for CD1 a on routinely fixed and processed tissue.

Abstract
The phenotypic and biologic properties of malignant cells in a case of aggressive mastocytosis with multi-organ involvement, circulating mast cell precursors and absence of skin infiltrates were analyzed. Circulating mast cell precursors were detected by immunostaining using antibodies against mast cell tryptase as well as by electron microscopy. These progenitors were tryptase+/chymase- (MCT) and accounted for 10 to 20% of nucleated mononuclear blood cells (MNC). A subset of them contained metachromatic granules. As assessed by combined toluidine blue/immunofluorescence staining, the granulated mast cell precursors were found to express CD9 (P24), CD33 (gp67) and CD44 (Pgp-1), but not basophil-related markers (CD11b (C3biR), CDw17 (lactosylceramide), CD123 (il-3R alpha))or monocyte-related antigens (CD14, CD15). Expression of the mast cell growth factor (MGF) receptor, c-kit(CD117), was also demonstrable, whereas the skin mast cell marker C5aR (CD88) could not be detected on mast cell precursors. The ligand of c-kit, recombinant human (rh) stem cell factor (SCF = MGF), induced histamine release from circulating mast cell progenitors, whereas rhC5a, a potent skin mast cell-/basophil-agonist, was ineffective over the dose-range (10(-9) to 10(-7(M)) tested. Analysis of mast cell antigens in malignant mastocytosis or mast cell leukemias may be helpful to establish a diagnosis and to determine the phenotype of the clone.

Abstract
Competitive polymerase chain reaction (PCR) systems were developed for rapid and quantitative estimation of HER-2 (c-erbB-2) and INT-2 oncogene amplification in paraffin-embedded ovarian cancer tissue samples. The beta-globin gene was used as reference and DNA from paraffin-embedded placenta tissue as single copy control. Reliability of the PCR method could be demonstrated by comparing dot blot data with PCR data of identical tumour samples. The PCR method was used to determine HER-2 and INT-2 copy numbers in 196 ovarian cancer samples. HER-2 and INT-2 were found to be amplified in 40 and 19%, respectively. In 8% HER-2 copy numbers were greater than five, but no high INT-2 copies were noted. Kaplan-Meier estimates did not reveal significant association with overall survival. Indirect correlation between HER-2 and INT-2 amplification was observed. The present PCR system is a valuable method for prospective and retrospective studies.

Abstract
A patient with peritoneal papillary serous carcinoma involving the colon and omentum is presented. Following palliative right-sided hemicolectomy and partial omentectomy, chemotherapy was given. The patient had a second look operation after 6 months when a pelvic clearance was done and histology revealed some residual tumor in one mesosalpinx. She was well and clinically free of recurrence after a further 6 months. Serum CA125 and CEA levels were measured and CA125 levels remained high throughout.
