Expert Review on Contemporary Management of Common Benign Pleural Effusions.
Heart failure (HF) and cirrhosis are frequently associated with pleural effusions (PEs). Despite their apparently benign nature, both HF-related effusions and hepatic hydrothorax (HH) have poor prognosis because they represent an advanced stage of the disease. Optimization of medical therapy in these two entities involve not only the use of diuretics, but also other pharmacological therapies. ⋯ Another benign condition, pleural tuberculosis (TB) is a serious health problem in developing countries. Diagnostic certainty is still a concern due to the paucibacillary nature of the infection, although the use of more sensitive nucleic acid amplification tests is becoming more widespread. Its treatment is the same as that of pulmonary TB, but the potential drug interactions between antiretroviral and anti-TB drugs in HIV-coinfected patients as well as the current recommended guidelines for the different types of anti-TB drugs resistance should be followed.

Objective : The hemodynamic parameters used to accurately predict fluid responsiveness (FR) in spontaneously breathing patients (SB) require specific material and expertise. Measurements of the central venous pressure (CVP) are relatively simple and, importantly, are feasible in many critically ill patients. We analyzed the accuracy of respiration-related variations in CVP (vCVP) to predict FR in SB patients and examined the optimization of its measurement using a standardized, deep inspiratory maneuver. ⋯ A vCVP-st < -4.7 mm Hg predicted FR with 89.5% sensitivity, a specificity of 56.0%, and an area under the receiver operating characteristic curve of 0.72 (95% CI, 0.58 to 0.86) ( P = 0.004). Conclusion : When a central venous catheter is present, elevated values for vCVP-st may be useful to identify spontaneously breathing patients unresponsive to volume expansion. Nevertheless, the necessity of performing a standardized, deep-inspiration maneuver may limit its clinical application.

Case Reports
Cervical Instability and Quadriparesis Requiring Stabilization in Pediatric Patient due to a Mutation in COL2A1.
A 3-year-old male with no past medical history presented with flaccid plegia of his upper extremities and significant weakness in his lower extremities after wrestling with his brother. Cervical spine magnetic resonance imaging was consistent with cord edema and intraparenchymal hemorrhage at C1-C2. A nonossified tissue mass at the expected location of the upper dens created narrowing of the canal at the C1-2 level and mass effect on the cord. ⋯ Genetic testing showed a COL2A1 collagen disorder, with the child harboring a de novo mutation for c.3455 G>T (p. G1152V). The patient was discharged to inpatient acute rehabilitation, with gradual improvement in strength in all 4 extremities.
