BACKGROUND Mannitol is a hyperosmolar agent and the combination of mannitol and furosemide is a widely used treatment for intracranial pressure *** the hypertonic properties of mannitol to move water out of intracellular spaces,we hypothesized that mannitol combined with furosemide could relieve focal tissue swelling in refractory *** SUMMARY A 90-year-old female had been diagnosed with intracranial hemorrhage and received a combination of mannitol and furosemide for intracranial pressure *** of the intracranial hemorrhage,she had refractory lymphedema of the left lower extremity since ***,after receiving the mannitol and furosemide,the patient’s lower extremity lymphedema improved *** the mannitol and furosemide were discontinued,the lymphedema worsened in spite of complete decongestive therapy(CDT)and intermittent pneumatic compression treatment(IPC).To identify the presumed effect of mannitol and furosemide on the lymphedema,these agents were resumed,and the lymphedema improved *** The present case raises the possibility that a combination of mannitol and furosemide might be considered another effective therapeutic option for refractory lymphedema when CDT and IPC are ineffective.

BACKGROUND Extracorporeal shock wave therapy (ESWT) can be applied to variousmusculoskeletal conditions including calcific tendinitis. Muscle injuries can leadto hematomas, and unabsorbed hematomas sometimes cause pain. We report acase of painful hematoma successfully treated with ESWT. To our knowledge, thisis the first reported case of painful intramuscular hematoma treated with *** SUMMARY A 65-year-old man visited the outpatient department for left calf pain withswelling that had persisted since he slipped two weeks prior. The calf pain hadpersisted and was rated visual analog scale 7. On physical examination, there wasa localized, stiff, ovoid mass on his left upper posterior calf. The pain wasaggravated by dorsiflexion of the left ankle or weight-bearing on the left *** diagnostic ultrasonography showed a hematoma in the left gastrocnemiusmuscle;its texture was firm with low heterogeneity. We applied ESWT to thehematoma. His pain decreased immediately to a visual analog scale 3, and themass was softened. The texture of the hematoma became more heterogeneous onultrasonography. Due to planned overseas travel, he returned three months afterthe initial visit to report that the pain and swelling were dramatically relievedafter *** We propose that painful hematomas could be a new indication for ESWT. Furtherinvestigation on the effects of ESWT for hematomas is needed.
