Air leak syndrome includes pulmonary interstitial emphysema, pneumothorax, pneumomediastinum, pneumopericardium, pneumoperitoneum, subcutaneous emphysema, and systemic air embolism. The most common cause of air leak syndrome in neonates is inadequate mechanical ventilation of the fragile and immature lungs. The incidence of air leaks in newborns is inversely related to the birth weight of the infants, especially in very-low-birth-weight and meconium-aspirated infants. ⋯ In conclusion, neonatal air leaks may present as a thoracic emergency requiring emergent intervention. To prevent air leak syndrome, gentle ventilations are key to caring for ventilated infants. There is insufficient evidence showing the role of HFOV and HFJV in the prevention or reduction of new air leaks in newborn infants, so further investigation will be necessary for future applications.

A 36-year-old male had spontaneous intracranial hypotension (SIH) presenting with refractory headache for 4 months. Multiple epidural blood patches (EBPs) yielded relief of symptoms, but the course was complicated, with asymptomatic intracranial subdural hematoma (SDH). Except for SDH, other radiological diagnostic signs of SIH were resolved and the patient's headaches improved after EBP. ⋯ It was reduction rather than elimination of the spinal CSF leak that yielded remission of SIH. In summary, intracranial SDH can be a complication of inadequately treated SIH (i.e. persistent minor CSF leakage). Management of SDH should focus on correction of the underlying SIH rather than craniotomy for hematoma evacuation.

Metaplastic carcinoma of the breast (MPCB) is a rare breast cancer. We reviewed sonographic findings for MPCB. ⋯ MPCB is a rare rapidly growing tumor. US findings included gently lobulated, complex mass lesion with cystic parts and posterior acoustic enhancement, representing necrosis or hemorrhage. Increased color flow signals and relative high RI of the feeding arteries were also seen.

The relationship between biochemical aspirin resistance (AR) and functional outcome of acute ischemic stroke is uncertain. ⋯ Aspirin resistance evaluated by PFA-100 test was associated with unfavorable 90-day outcome. However, AR determined by PFA-100 dose not predict 90-day functional outcome. The results of PFA-100 testing represented a complex interaction between drug effect, inflammatory reaction, and prothrombotic activity.

The left ventricular assist device (LVAD) is a battery-operated, mechanical pump-type device that helps in maintaining the pumping ability of a failing heart. Thromboembolism poses a significant risk during and after LVAD implantation. It occurs in up to 35% of patients with adverse sequelae. ⋯ We believe that TEE monitoring aided the implantation and removal of the LVAD device. In this case, we found that TEE not only helped in monitoring the ventricular function but also in detecting other problems such as the residual thrombus. We strongly recommend TEE monitoring during the entire LVAD-removal procedure, particularly for patients who need to undergo LVAD removal because of thrombosis formation.
