Cerebral Venous Thrombosis in Hematological Malignancy: Balancing the Risks.

BACKGROUND AND AIM: The coexistence of cerebral venous thrombosis (CVT) and hematological neoplasms is rare. Currently available therapeutic options raise problems concerning the balance of thrombotic and hemorrhagic risks. Our purpose is to characterize a series of cases of CVT and concomitant hematological malignancy, focusing on predisposing factors and treatment strategies. METHODS: We performed a descriptive retrospective analysis of the cases of CVT and hematological neoplasms diagnosed in a tertiary center from 2006 to 2015. RESULTS: From the 111 CVT cases diagnosed, only 7 coexisted with hematological malignancy (lymphoma, leukemia, multiple myeloma, and myelodysplastic syndromes). These included 4 women; median age was 44 years old. Median follow-up time was 72 days. The hematological condition was already known in 5 cases. Besides malignancy, we identified other prothrombotic conditions in all cases. Several anticoagulant strategies were used during the acute phase, after which 5 patients remained on warfarin indefinitely. One patient died due to cerebral hemorrhage during the acute phase. In the remaining 6 patients, there was no recurrence of CVT or other complications of anticoagulation. CONCLUSIONS: Although these results reiterate the role of hematological malignancy as predisposing factor to CVT, in all cases other factors contributed to CVT etiology, potentiating the risk. We report 1 death directly attributable to a fatal hemorrhagic complication of anticoagulation, evidencing the delicate balance of thrombotic and hemorrhagic risk. Nevertheless, most patients benefited of long-term anticoagulation, which proved a reasonable option. A multidisciplinary approach is paramount in making decisions regarding the time and type of anticoagulation.

Clinical features of hypertrophic pachymeningitis in a center survey.

BACKGROUND: Hypertrophic pachymeningitis (HP) is characterized by cranial and/or spinal thickening of the dura mater with or without associated inflammation. Neuroimaging studies reveal dura mater thickening and focal or diffuse contrast enhancement. It is described in association with trauma, infections, tumors, autoimmune/inflammatory diseases, and cerebrospinal fluid hypotension syndrome, with some cases remaining idiopathic. METHODS: A retrospective study was conducted with patients' identification through a key terms search within MRI reports in the period of July 2008 to September 2015. Clinical files, MRI, laboratory, and pathology data were reviewed. RESULTS: Fifty-three patients were identified and 20 were excluded because they did not meet the inclusion criteria. Of the 33 included, 19 were female, with a mean age at symptoms onset of 51.2 ± 17.6 years. The most common presenting symptoms were headache and cranial nerves palsy, followed by seizures, delirium, lumbar pain, cognitive decline, motor deficit, and language impairment. In 17 patients, a neoplastic etiology was identified; in eight, inflammatory/autoimmune; in six, infectious; and two were classified as idiopathic. Of the eight patients with inflammatory/autoimmune etiology, four had possible IgG4-related disease (IgG4-RD) and the remaining had granulomatosis with polyangiitis, sarcoidosis, rheumatoid arthritis, and Tolosa-Hunt syndrome. Treatment was directed according to the underlying etiology. DISCUSSION: In the described series, a female predominance was identified, with symptoms' onset in the 5th decade. Although headache was the most common symptom, clinical presentation was varied, emphasizing the role of MRI in HP diagnosis. The underlying etiologies were diverse, with only a few cases remaining idiopathic, also reflecting the contribution of the recently described IgG4-RD.

Enlarging Red Blood Cell Distribution Width During Hospitalization Identifies a Very High-Risk Subset of Acutely Decompensated Heart Failure Patients and Adds Valuable Prognostic Information on Top of Hemoconcentration.

Red blood cell distribution width (RDW) may serve as an integrative marker of pathological processes that portend worse prognosis in heart failure (HF). The prognostic value of RDW variation (ΔRDW) during hospitalization for acute heart failure (AHF) has yet to be studied.We retrospectively analyzed 2 independent cohorts: Centro Hospitalar do Porto (derivation cohort) and Lariboisière hospital (validation cohort). In the derivation cohort a total of 170 patients (age 76.2 ±â€Š10.3 years) were included and in the validation cohort 332 patients were included (age 76.4 ±â€Š12.2 years). In the derivation cohort the primary composite outcome of HF admission and/or cardiovascular death occurred in 78 (45.9%) patients during the 180-day follow-up period.Discharge RDW and ΔRDW were both increased when hemoglobin levels were lower; peripheral edema was also associated with increased discharge RDW (all P < 0.05). Discharge RDW value was significantly associated with adverse events: RDW > 15% at discharge was associated with a 2-fold increase in event rate, HR = 1.95 (1.05-3.62), P = 0.04, while a ΔRDW >0 also had a strong association with outcome, HR = 2.47 (1.35-4.51), P = 0.003. The addition of both discharge RDW > 15% and ΔRDW > 0 to hemoconcentration was associated with a significant improvement in the net reclassification index, NRI = 18.3 (4.3-43.7), P = 0.012. Overlapping results were found in the validation cohort.As validated in 2 independent AHF cohorts, an in-hospital RDW enlargement and an elevated RDW at discharge are associated with increased rates of mid-term events. RDW variables improve the risk stratification of these patients on top of well-established prognostic markers.

Spot urine sodium excretion as prognostic marker in acutely decompensated heart failure: the spironolactone effect.

INTRODUCTION: Loop diuretic resistance characterized by inefficient sodium excretion complicates many patients with acutely decompensated heart failure (ADHF). Mineralocorticoid receptor antagonists (MRAs) in natriuretic doses may improve spot urine sodium excretion and outcomes. OBJECTIVE: Our primary aim was to assess the association of high-dose spironolactone with short-term spot urine sodium excretion, and our secondary aim was to determine if this higher short-term spot urine sodium excretion is associated with reduction in the composite clinical outcome (of cardiovascular mortality and/or ADHF hospitalization) event rate at 180 days. METHODS: Single-centre, non-randomized, open-label study enrolling 100 patients with ADHF. Patients were treated with standard ADHF therapy alone (n = 50) or oral spironolactone 100 mg/day plus standard ADHF therapy (n = 50). Spot urine samples were collected at day 1 and day 3 of hospitalization. RESULTS: Spironolactone group had significantly higher spot urine sodium levels compared to standard care group at day 3 (84.13 ± 28.71 mmol/L vs 70.74 ± 34.43 mmol/L, p = 0.04). The proportion of patients with spot urinary sodium <60 mmol/L was lower in spironolactone group at day 3 (18.8 vs 45.7, p = 0.01). In multivariate analysis, spironolactone was independently associated with increased spot urinary sodium and urinary sodium/potassium ratio of >2 at day 3 (both, p < 0.05). Higher spot urine sodium levels were associated with a lower event rate [HR for urinary sodium >100 mmol/L = 0.16 (0.06-0.42), p < 0.01, compared to <60], and provided a significant prognostic gain measured by net reclassification indexes. CONCLUSION: Spot urinary sodium levels >60 mmol/L and urinary sodium/potassium ratio >2 measured at day 3 of hospitalization for ADHF are associated with improved mid-term outcomes. Spironolactone is associated with increased spot urinary sodium and sodium/potassium ratio >2.

Rhinocerebral mucormycosis: literature review apropos of a rare entity.

Mucormycosis is a rare fungal infection that affects immunocompromised patients, and the rhinoorbitocerebral presentation is the most common clinical form of the disease, often associated with diabetes mellitusThe treatment is complex and involves amphotericin B and surgery. Studies show increasing success without or with minimal surgeries. The authors present the case of a diabetic woman with a 1-month history of intranasal and right periorbital pain associated with progressive deficit of various cranial nerves, sudden amaurosis and homolateral ptosis. Rhizopus oryzae species was identified in pus in the nasal mucosa. She was treated with antifungal therapy and minimal surgical debridement with success. The authors decided on publication because of the rarity of this entity, alerting for the need of a high suspicion index for the diagnosis, which should be made as early as possible due to the high mortality rate, as well as presenting data about the increasing discussion of therapeutic strategies, with some new approaches that prioritise minimal surgeries.
