Abstract
The BCR-ABL-negative myeloproliferative neoplasms (MPN) are associated with high incidence of venous thrombosis and a significant rate of recurrent events, but there is no consensus regarding their management. In this retrospective study, we analyzed 96 patients with MPN-related venous thrombosis. The index venous thrombosis occurred at a median age of 58 years (IQR 37-71), with 58% of the events involving unusual sites. Patients who were on antiplatelet agents at the time of index thrombosis tended to be older than patients who were not receiving antiplatelets at the time of index thrombosis. The majority of index thromboses occurring after the diagnosis of MPN had uncontrolled blood counts at the time of event and were not receiving antithrombotic agents. Following the thrombotic episode, 75% of patients received long-term anticoagulation. At a median follow-up of 3.4 years, the recurrence rate was 14%. Thrombophilia was significantly more prevalent among patients with recurrent thrombosis compared to patients without recurrence (p < 0.01). Patients who developed a recurrent event early were more likely to have thrombophilia (either inherited or antiphospholipid antibodies), and controlled blood counts, and were likely to receive anticoagulation at the time of recurrence compared to patients with later recurrences. Thrombophilia may contribute to venous thrombosis recurrence, especially early after the index venous thrombosis. Suboptimal anticoagulation and blood count control are factors associated with late venous thrombosis recurrence.

Abstract
INTRODUCTION Thoracic endometriosis (TE) is a rare disorder affecting women during their reproductive years. Manifestations of TE include pneumothorax and haemothorax. Treatment is based on surgical and hormonal therapy that aims at eradicating existing endometrial thoracic plaques and to prevent reseeding from pelvic endometriosis. CASE REPORT We report the case of a 36 year-old young woman presenting thoracic endometriosis revealed by a recurring spontaneous, large and isolated right haemothorax. Diagnosis, pathogeny and treatment are discussed. CONCLUSION Thoracic endometriosis needs to be considered as a cause of haemothorax in women of childbearing age.

Prothrombin Complex Concentrate before Urgent Surgery in Patients Treated with Rivaroxaban and Apixaban. Acta Haematol 2019; 143:266-271. [PMID: 31610537 DOI: 10.1159/000502173] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2019] [Accepted: 07/06/2019] [Indexed: 02/06/2023]
Abstract
INTRODUCTION Patients treated with direct Xa inhibitors may require urgent surgery. Administration of prothrombin complex concentrate (PCC) in this setting is common; however, it is based on limited experience in healthy volunteers. OBJECTIVE To characterize the population receiving PCC for apixaban/rivaroxaban reversal prior to an urgent surgery and evaluate its efficacy and safety. METHODS This was a retrospective study in 2 tertiary hospitals. Bleeding was evaluated based on surgical reports, hemoglobin drop, and the use of blood products or additional PCC during 48 h. Safety measures were thrombotic complications and 30-day mortality. RESULTS Sixty-two patients aged 80.7 ± 9 years, treated with apixaban (39.63%) or rivaroxaban (23.37%), received PCC before an urgent surgery/procedure. Most underwent abdominal operation (61%), orthopedic surgery (13%), or transhepatic cholecystostomy insertion (10%). Bleeding during surgery was reported in 3 patients (5%), no patient required additional PCC, and 16 patients (26%) received packed cells (median: 1 unit, range: 1-5). The 30-day mortality and thrombosis rates were 21% (n = 13) and 3% (n = 2), respectively. The cause of death was related to the primary disease, most commonly sepsis. No patient died due to bleeding/thrombosis. CONCLUSIONS Our results support the use of PCC to achieve hemostasis in patients treated with Xa inhibitors prior to an urgent surgery.

Abstract
OBJECTIVE Approximately 10% of Philadelphia (Ph)-negative myeloproliferative neoplasms (NPM) are diagnosed at young adulthood. We aim to define the features of this group. METHODS A multicenter retrospective study, including patients 18-45 years of age, diagnosed with Ph-negative MPN between 1985 and 2017. RESULTS One hundred nine patients were included, 37 with polycythemia vera (34%), 54 with essential thrombocytosis (50%), 15 with primary myelofibrosis (PMF) (14%), and 3 with MPN unclassifiable (3%). Median age was 33 years and 62 (57%) were females. During a median follow-up of 8 years, 39 patients (37%) had at least one thrombotic event. 30/39 of events were venous (77%), 23/30 of which were splanchnic (77%). In 14/39 (36%), thrombosis preceded MPN diagnosis. In a multivariable analysis, only splenomegaly predicted for thrombosis (HR 5.6, CI: 1.4-22). The 10-year risk for secondary myelofibrosis was similar for ET and PV (0.13 vs 0.19, P = 0.51). The 10-year risk for leukemic transformation or mortality was significantly higher for PMF (0.3, P = 0.04). CONCLUSIONS The risks of mortality and of progression to MF/leukemia in young adults are similar to older population. Thrombotic events are frequently a presenting sign with a high incidence of venous, in particular splanchnic, events.

Abstract
Hematological malignancy during pregnancy is a rare event, therefore most data on this issue is based on case studies, retrospective studies and expert opinion. The purpose of the present narrative review was to provide an overview of the diagnosis and recommended management of the most common hematological malignancies during pregnancy, based on current literature, with clinical cases, and discussion of the diagnostic and therapeutic options. The therapeutic consensus while coping with hematological malignancies in pregnancy is to salvage the mother, while trying to preserve pregnancy and avoid treatment-related-toxicity to the fetus. In most scenarios, particularly during late trimesters, the goal is to administer the same treatment as outside of pregnancy, if possible. Further research is needed for better evidence-based management.

Abstract
Hodgkin lymphoma (HL) is one of the most curable malignancies. Despite its effectiveness, chemotherapy is often associated with adverse events (AEs) such as nausea, anorexia, and impairment of general well-being. Our objective was to assess the extent of medical cannabis use among HL patients and evaluate its efficacy in controlling chemotherapy-related AEs. Patterns of medical cannabis use and efficacy were evaluated using physician-completed application forms, medical files, and patient-completed questionnaires, for all consecutive adult HL patients treated at the Tel-Aviv Medical Center between June 2010 and November 2016. One-hundred and thirty-three patients met the inclusion criteria. The median age of the cohort was 37 years, 53% were male, 46% were diagnosed at an early stage, and 88% achieved a complete response to treatment. Fifty-one patients (38%) used medical cannabis. There were no significant differences in baseline characteristics between cannabis users and nonusers. Cannabis users reported improvement in pain, general well-being, appetite, and nausea in 94, 87, 82, and 79% of cases, respectively. Importantly, 81.5% reported a high overall efficacy of cannabis in relieving symptoms. AEs related to cannabis use itself were mild. Thus, medical cannabis use is prevalent in this HL cohort, and appears to be effective in ameliorating chemotherapy-related AEs.

Abstract
BACKGROUND Renal vein thrombosis (RVT) is a rare event with myriad clinical manifestations. Published experience regarding the clinical course and management of RVT in patients beyond the neonatal period is limited to case reports and small case series. METHODS A multicenter retrospective review of consecutive admitted patients with diagnosed RVT between January 2000 and May 2015 at three different university hospitals. RESULTS Thirty-nine patients (53.8 % men and 46.2 % women) were included. Median age was 58 years. Malignancy (n = 19, 48.7 %), nephrotic syndrome (n = 8, 20.5 %) and infection (n = 5, 12.8 %), were the most common underlying conditions. Compared to non-cancer patients, patients with active cancer tended to be significantly older (mean age 63 ± 18 vs. 37 ± 22 years, P = 0.001) and presented with non-acute symptoms (P = 0.01) and unrevealing physical findings (P = 0.02). Thrombosis extension beyond the renal vein occurred in 69.2 % of cases and was more common in cancer patients (P = 0.001). Anticoagulation therapy was administered in 71.8 % of patients leading to resolution of thrombus in most cases (30/32 patients, 94 %) during follow-up evaluation. There were six recurrent thrombotic events during a mean follow-up of 35 ± 43 months. Nine patients (28 %) died during follow-up, all of them with malignancy. CONCLUSION Active cancer is the most common cause of RVT and should be excluded when RVT is diagnosed. Clinical course of RVT in cancer patients is more indolent and diagnosis requires high index of suspicion. Survival rates are governed by the presence of malignancy.

Abstract
Alterations in chronic lymphocytic leukemia (CLL) cell metabolism have been studied by several investigators. Unlike normal B lymphocytes or other leukemia cells, CLL cells, like adipocytes, store lipids and utilize free fatty acids (FFA) to produce chemical energy. None of the recently identified mutations in CLL directly affects metabolic pathways, suggesting that genetic alterations do not directly contribute to CLL cells' metabolic reprogramming. Conversely, recent data suggest that activation of STAT3 or downregulation of microRNA-125 levels plays a crucial role in the utilization of FFA to meet the CLL cells' metabolic needs. STAT3, known to be constitutively activated in CLL, increases the levels of lipoprotein lipase (LPL) that mediates lipoprotein uptake and shifts the CLL cells' metabolism towards utilization of FFA. Herein, we review the evidence for altered lipid metabolism, increased mitochondrial activity and formation of reactive oxygen species (ROS) in CLL cells, and discuss the possible therapeutic strategies to inhibit lipid metabolism pathways in patient with CLL.

Abstract
The fibromyalgia syndrome (FMS) is considered to result from the exposure of a genetically susceptible individual to various triggers, such as physical trauma, stress, viral infections etc. A possible role of vaccination in FMS etiology has been suspected. Our objective was to evaluate the efficacy and safety of influenza vaccination in FMS patients. Nineteen FMS patients underwent physical and dolorimetric examinations and answered the fibromyalgia impact questionnaire (FIQ), the widespread pain index (WPI) checklist and the symptoms severity scale (SSS), which are part of the 2010 diagnostic criteria. Thirty-eight healthy subjects were recruited as controls. All participants were vaccinated with the inactivated split virion influenza vaccine. Serum was collected for antibody titration. Six weeks after vaccination, sera were tested by hemagglutination (HI) against A/California (H1N1), A/Perth (H3N2) and B/Brisbane. Humoral response was defined as either a fourfold or greater increase in titer, or an increase from a non-protective baseline level of <1/40 to a level of 1/40. No severe vaccination reactions were observed. No significant change was observed between WPI, SSS and FIQ values before and after vaccination, indicating no worsening of FMS symptoms. Vaccine immunogenicity: Six weeks after vaccination, FMS patients showed a significant increase in geometric mean titers of HI antibody. The rates of sero-protection increased from 22.9% for H1N1 to 89.5% post-vaccination. A significant increase in HI antibody titers was also demonstrated among healthy controls. Influenza vaccination was both safe and effective in FMS patients. In view of these results, FMS patients should be encouraged to undergo influenza vaccination according to the standard WHO recommendations.

Abstract
BACKGROUND Postural tachycardia syndrome (POTS) is a common form of chronic orthostatic intolerance. The remarkable increase in heart rate (HR) upon standing is the hallmark of this syndrome. Treatment of POTS patients is challenging and includes drugs that slow the HR. Ivabradine is a selective If channel blocker designed to slow the HR, as an anti-anginal agent. In view of its ability to slow the HR, we posited that ivabradine may be an ideal medication for treating POTS patients. This report provides the results of an investigation in which we studied ivabradine's effect on the hemodynamics and sympathovagal balance in POTS patients. METHODS An open-label trial, without a placebo control, was performed in eight patients with POTS of two years' standing. Characterization of symptoms, hemodynamics, autonomic function tests, and HR and blood pressure (BP) variability were determined while patients were in a supine position and during a 20-minute head-up tilt before and after a single oral dose of 7.5 mg ivabradine. RESULTS Ivabradine slowed the HR of POTS patients at rest by 4±1 bpm (P<0.05). During a 5-minute head-up tilt, the HR decreased from 118±4 bpm to 101±5 bpm (P<0.01). Ivabradine did not affect the BP when patients were at rest in a supine position or in head-up tilt position. Cardiovascular vagal and sympathetic tone, extrapolated from the time and frequency domains of the HR and BP variability, were also not affected by ivabradine. CONCLUSIONS Ivabradine is an effective drug for slowing the HR of POTS patients at rest and during tilting, without producing significant adverse effects. Moreover, ivabradine exerts its effects without influencing the sympathovagal balance.

Abstract
Seronegative spondyloarthritis (SpA) represents a group of diseases that share certain genetic, clinical, and radiographic features. Enthesitis, inflammation at the site of tendon insertion into the bone, involving both the axial and the peripheral joints, is an important sign of SpA. Clinical diagnosis of enthesitis, however, is neither sensitive nor specific; thus, the diagnosis of enthesitis often relies on typical abnormalities in imaging studies. Due to its low costs and availability, ultrasound is emerging as the preferred technique for detection of enthesitis for both clinical and research purposes. Ultrasonographic features of enthesitis include tendon hypoechogenicity and thickening, calcifications, bone erosions, and Doppler signal. Several semi-quantitative scoring systems have been developed to quantify ultrasonographic abnormalities of the entheses. These methods have been used for early diagnosis and classification of SpA as well as for monitoring response to treatment.

Abstract
BACKGROUND Intentional selective occlusion of the arterial blood supply to tumors of abdominal organs is a well established therapeutic procedure. Several reports described gas accumulation at the infarcted sites. These gas collections are usually nonsuppurative; however, the differential diagnosis should include abscess formation. CASE REPORT We present a 59-year-old patient in whom the splenic artery was accidentally ligated during gastrectomy surgery, with resultant splenic infarction. Gas accumulation was diagnosed by sonography and CT studies. To the best of our knowledge this is the first report ever published in the English medical literature describing nonsuppurative gas formation within an abdominal organ, caused by accidental ligation of its main arterial supply during surgery. SUMMARY Possible theories regarding this noninfectious gas accumulation are discussed and the differential diagnosis between abscess formation and noninfectious gas accumulation is emphasized. Establishing the correct diagnosis is of big clinical importance as the treatment of choice is completely different in each one of these entities although the imaging features, in ultrasound as well as in CT, are somewhat similar.

Abstract
The unique appearance of a midline prostatic cyst is reported. The cyst presented as a round-shaped filling defect at the base of the urinary bladder during an intravenous pyelography study. Transabdominal sonography showed the mass to be a midline prostatic cyst. The sonographic features of the mass and its location are the hallmark of a müllerian duct prostatic cyst. Midline prostatic cysts are discussed and the features differentiating müllerian duct cysts from utricle cysts are emphasized.

Abstract
Reported herein is a 41-year-old male who presented for ultrasound due to two episodes of lower urinary tract infections within a period of 5 months. The sonographic examination revealed an elongated foreign body in the urethra extending into the urinary bladder. Self-insertion of foreign bodies into the urethra is usually done for erotic stimulation. However, foreign bodies can be inserted by children due to curiosity and by mentally retarded people, patients with psychiatric disorders as well as by intoxicated patients and in confusional states. Due to embarrassment, the patients seek medical help only when they are symptomatic and hence some of the foreign bodies are removed only several months after insertion. Detection might be either by plain abdominal films when the foreign bodies are radiopaque or by the use of contrast media. In the case presented by us, this was done by sonography. Endoscopic removal of these foreign bodies is considered the treatment of choice. Recurrent or chronic unexplained urinary tract infections should raise a high index of suspicion to the possible existence of a foreign body in the urethra and/or urinary bladder.

Abstract
Laparoscopic cholecystectomy is considered the procedure of choice for removing symptomatic, stone-containing gallbladders. It is estimated that in 30-40% of these operations stone(s) spill into the peritoneal cavity. It was assumed that these "dropped stones" are harmless and are dissolved and absorbed spontaneously. We present a 70-year-old woman in whom such a stone, dropped during laparoscopy, led to formation of an intraperitoneal abscess.

Abstract
Trichobezoars are accumulations of hair casts in the stomach associated with trichophagia. The typical patient is an adolescent female who presents with alopecia and an upper abdominal mass which on moving can cause intermittent gastric outlet obstruction. Only a minority of patients have severe psychiatric disorders. When hair strands extend from the main mass in the stomach, all along the small bowel and reaching the cecum, the condition is termed the Rapunzel syndrome. In about 5% of patients there are separate hair masses in the stomach. The clinical presentation includes abdominal pain, loss of appetite, weight-loss, vomiting, loose stools, pancreatitis, jaundice, anemia and hypoalbuminemia. These signs and symptoms raise the suspicion of malignancy. Complications of bezoars include ulcers, perforation of the bowel, obstruction and intussusception. Diagnosis can be established either by barium swallow or by CT scan. Ultrasound might suggest the diagnosis, but sonographic features are definitely not pathognomonic. Treatment is surgical, as endoscopic removal is usually unsuccessful. We present 2 children in whom trichobezoars were found.

Abstract
Following an unsuccessful liver biopsy in a 16-year-old girl in which only bile was obtained, a sonographic (US) study was performed. The findings were those of free fluid just adjacent to the gallbladder as well as a small intraluminal protrusion of the gallbladder wall. The US features of the gallbladder finding were consistent with a polyp. Gallbladder polyps are very rare in children, however, sporadic case reports do exist. An US study 24 h after the invasive procedure revealed complete regression of the free fluid; the gallbladder wall protrusion has disappeared. We suggest that the tip of the biopsy needle had penetrated the gallbladder wall and caused a bile leak. The needle penetration caused elevation of the inner wall layer at the entrance site, which was indistinguishable from the sonographic findings of a gallbladder polyp [1-4]

Abstract
A simple, rapid high-performance liquid chromatography method has been devised in order to separate and quantify the xanthophylls capsorubin and capasanthin present in red pepper (Capsicum annuum L.) fruits and preparations made from them (paprika and oleoresin). A reversed-phase isocratic non-aqueous system allows the separation of xanthophylls within a few minutes, with detection at 450 nm, using methyl red as internal standard to locate the various carotenoids and xanthophylls found in plant extracts. The selection of extraction solvents, mild saponification conditions, and chromatographic features is evaluated and discussed. The method is proposed for rapid screening of large plant populations, plant selection, as well as for paprika products and oleoresin, and also for nutrition and quality control studies.

Abstract
Although gallbladder polyps are well documented in adults, only three cases in children have been reported in the literature. We present two pediatric cases in which gallbladder polyps were detected by ultrasound, confirming this as the imaging method of choice in diagnosing gallbladder disease.

Abstract
The round worm, Ascaris lumbricoides, is one of the largest of the parasites that infest the human bowel. The worms usually develop in the jejunum and can reach several thousand in number, causing bowel obstruction, volvulus, intussusception, appendicitis and even bowel perforation with penetration into the peritoneal cavity. They tend to invade the bile and pancreatic ducts and may cause acute cholecystitis and pancreatitis. Ascaris lumbricoides can be detected by sonography. This imaging modality can be helpful in diagnosing the presence of the worms and in evaluating response to treatment. We present an 18-month-old girl in whom bowel worms were detected by sonography.

Abstract
A case of congenital urethral polyp in a 10-month-old boy is presented. These rare congenital tumors can lead to urinary retention, hematuria, urinary tract infections, hydronephrosis and hydroureter. Traditionally the diagnosis was based either on voiding cystourethrography or cystoscopy. The sonographic features of these polyps have only been reported in a few cases in the past. This modality is not infrequently the imaging procedure of choice in the work-up of children with signs and symptoms related to the urinary system. In the case presented herein the polyp was demonstrated initially by sonography as a soft tissue mass arising at the base of the urinary bladder. The differential diagnosis of these lesions is presented.
