ABSTRACT

Hyperleukocytic acute myeloid leukemia (AML) is associated with pulmonary complications and high early mortality rate, but given its rarity, data on chest radiographic presentation are scarce.We retrospectively reviewed the charts of 73 AML patients admitted with white blood cell count >100 × 10/L between 2003 and 2014 in order to describe the chest radiographic and computed tomography (CT) findings and to correlate them with AML subtype and respiratory symptoms.Forty-two of the 73 patients (58%) overall and 36 of the 54 patients (67%) with clinical signs of pulmonary leukostasis had abnormal radiographs on admission. The presence of radiographic abnormalities was significantly associated with dyspnea and oxygen/ventilatory support requirements (P < 0.01) and with day 28 mortality (45% vs 13%, P = 0.005) but not with monocytic subtype of AML. Sixteen patients had isolated focal basilar airspace opacities, unilateral (n = 13) or bilateral (n = 3), while 16 patients had bilateral diffuse opacities, interstitial (n = 12) or airspace and interstitial (n = 4). Two patients had isolated pleural effusion, 2 patients had unilateral midlung airspace opacities, and 6 patients had a combination of focal airspace and diffuse interstitial opacities. Overall, 2 patterns accounted for 75% of abnormal findings: bilateral diffuse opacities tended to be associated with monocytic AML, whereas basilar focal airspace opacities were more frequent in nonmonocytic AML (P < 0.05). Eighteen patients had CT scans, revealing interlobular septal thickening (n = 12), airspace (n = 11) and ground-glass (n = 9) opacities, pleural effusions (n = 12), and acute pulmonary embolism (n = 2).Hyperleukocytic AML is frequently associated with abnormal chest radiographs, involving mostly focal basilar airspace opacities (more frequent in nonmonocytic AML) or diffuse bilateral opacities. CT scan should be considered broadly due to the suboptimal resolution of radiographs for detecting signs of leukostasis.

ABSTRACT

The use of intrapleural therapy with tissue plasminogen activator and DNase improves outcomes in patients with complicated pleural space infections. However, little data exists for the use of combination intrapleural therapy after the initial dosing period of six doses. We sought to describe the safety profile and outcomes of intrapleural therapy beyond this standard dosing. A retrospective review of patients receiving intrapleural therapy with tissue plasminogen activator and DNase was performed at two institutions. We identified 101 patients from January 2013 to August 2015 receiving intrapleural therapy for complicated pleural space infection. The extended use of intrapleural tissue plasminogen activator and DNase therapy beyond six doses was utilized in 20% (20/101) of patients. The mean number of doses in those undergoing extended dosing was 9.8 (range of 7-16). Within the population studied there appears to be no statistically significant increased risk of complications, need for surgical referral, or outcome differences when comparing those receiving standard or extended dosing intrapleural therapy. Future prospective study of intrapleural therapy as an alternative option for patients who fail initial pleural drainage and are unable to tolerate/accept a surgical intervention appears a potential area of study.

ABSTRACT

Henoch-Schönlein purpura is a common small-vessel vasculitis that presents in children as nonthrombocytopenic, nontender, and palpable purpura, arthritis/arthralgia, and abdominal pain. Central nervous system involvement is a reported, but likely, under-recognized complication. We present an 8-year-old boy with Henoch-Schönlein purpura and posterior reversible encephalopathy syndrome, after proposed mechanism and treatment considerations.

ABSTRACT

Viral bronchiolitis accounts for almost 20% of all-cause hospitalizations of infants (ie, children younger than age 1 year). The annual incidence of fever in viral bronchiolitis has been documented at 23% to 31%. However the incidence of concurrent serious bacterial infections is low (1%-7%), with meningitis occurring in less than 1% to 2% of cases, but lumbar puncture is performed in up to 9% of viral bronchiolitis cases. To our knowledge, no study has examined clinical factors that influence a physician's decision to perform a lumbar puncture in the setting of viral bronchiolitis. We present a retrospective, case-control study of hospitalized infants younger than one year diagnosed with viral bronchiolitis who underwent lumbar puncture as part of an evaluation for meningitis. The objective of the study was to determine clinical factors that influence a physician's decision to perform a lumbar puncture in the setting of viral bronchiolitis. Although the presence of apnea, cyanosis, meningeal signs, positive urine culture results, and young age were factors found to be preliminarily associated with the performance of a lumbar puncture in the setting of bronchiolitis, young age was the only significant clinical factor found after multivariable regression; no other demographic, clinical, laboratory, or radiologic variables were found to be significant.

ABSTRACT

OBJECT: Aneurysms treated by endovascular coil embolization have been associated with coil compaction, and the rate of recanalization has been reported to be as high as 40%. The authors report the first published evidence of a correlation between aneurysm recanalization correlated with a history of cigarette smoking. METHODS: The authors conducted a retrospective chart review of all cases involving patients admitted to their institution from January 1, 2003, to December 31, 2003, for treatment of a cerebral aneurysm. Cases in which patients were treated with coil embolization were reviewed for inclusion. Coil compaction was defined as change in the shape of the coil mass. Aneurysm recanalization was defined as an increase in inflow to the aneurysm in comparison with baseline. The incidence of coil compaction and the relationship with cigarette smoking history were compared in patients with and without recurrence. RESULTS: A total of 110 patients qualified for inclusion. The odds ratio (OR) for aneurysm recanalization after endosaccular occlusion with respect to history of cigarette smoking was significant for the entire cohort (OR 4.53, 95% confidence interval [CI] 1.95-10.52) and especially for the female cohort (OR 3.72, 95% CI 1.45-9.54). The male cohort demonstrated a trend toward a direct correlation, but the sample size was not large enough for statistical significance (OR 7.50, 95% CI 1.02-55.00). CONCLUSIONS: There was an increased risk of recanalization especially in patients with low-grade subarachnoid hemorrhage who had a history of cigarette smoking. These data suggest a correlation between cigarette smoking and aneurysm recurrence.
