On a Clear DayHD

Reviewer #1: Authors describe a case series of patients with symptomatic large uremic pericardial effusion with narrow safety margins for pericardiocentesis with subxyphoid access. Patients underwent pericardiocentesis under echocardiographic and fluoroscopic guidance. The manuscript is written in clear standard English. It is a retrospective decription of the cases.

Until the interwar years (1918-1939), most mines were moored and activated by contact. These consisted of an anchor, cable, and mine. The entire assembly was dropped to the sea floor where the anchor and length of cable keep the mine at a preset depth. This type of mine rests below the surface, barely visible unless the water is clear and the weather is calm. Through World War I, the best method for sweeping these types of mines was to drag a cable between two ships, cutting the mooring cables and causing the mine to float to the surface where it would be destroyed by gunfire. Seems simple enough, however, this was not what was waiting for the ships of Mine Squadron Seven as they departed southern England on the evening of June 5, 1944.

Cracking the defenses of the Atlantic Wall had to begin with safe passage to the coast of France. This would not have been possible without the often-overlooked minesweeping force. The nature of their mission meant they had to be the first to go in, but also the nature of minesweeping did not guarantee they would completely clear a path in one go. Losses to mines were expected, and happened. Over a dozen landing craft, two destroyers, a destroyer escort, two troop ships, and three minesweepers of Mine Squadron 7, were lost to naval mines in the western beaches on June 6 and the days following. Many of these losses were the result of new and difficult to sweep German pressure mines. However, without the work of the minesweepers these losses could have started off the coast of England and not France. 041b061a72
