With a total of 577 medical evaluations, most of whom required laboratory work, there was considerable pressure on the laboratory to complete an indi- vidual's tests at the time of examination. The final tally of tests was: Complete blood counts, including white cell differentials and platelet counts: 475 Routine urinalyses: 475 Microscopic exams of urine: 61 Stools for ova and parasites: 18 Bacteriologic cultures: Blood chemistries: 68 Sedimentation rates: 40 15 Serum preparation for Path. Assoc.: Red Cell folate hemolysates: 169 Hb Aj, hemolysates: 62 Serum separation for BNL: 51 475 The success of this considerable effort can be attributed in great partto the renovated lab area on the. LiktanurI wish to express our thanks to Capt. Coberly for the expanded and more efficient and comfortable laboratory arrangements. Other diagnostic procedures, by the way, included 36 electrocardiograns, 150 pap smears, 250 stool exams for occult blood, and several tissue blopsies and proctoscopies. I mention them to give you some idea of the extent of the medical workup provided on board the Liktanur. I continue to be impressed with how such a small ship can so effectively support the variety of services we provide over a relatively short period of time. There was one potentially very serious problem on this survey, and, as you are aware, that was the lack of a functioning x-ray machine. It is most for- tunate that a situation requiring urgent x-ray diagnosis was not encountered at Rongelap and Utirik. It is certainly possible that a life could have been lost had we met with a patient who had a “surgical” abdomen or extensive trauma. (There could have been important information obtained in either of these events even though the present machine is not a powerful one). I know that the reason for the x-ray malfunction does not lie with your support services. I do hope, however, that the seriousness of the problem can be passed to those individuals who assured us that the machine would be in service. We should, in addition, begin to consider the x-ray unit which will be re- quired for the next trip. Given our fiscal limitations both at PASO and BNL this may be a problem. I did budget for a new machine this past January, but that would be for FY 1983-84. If we are forced into a new x-ray unit at this time we would consider the recommendation of Mr. Kosang Mizutani, the x-ray repair specialist in the Marshall Islands. He recommends a unit they now have at Majuro and apparently in other districts of the Trust Territory. He indi-~ cates it functions well (low frequency of repair necessary) and, in addition, they have parts and the expertise to handle repairs that do occur. This unit is manufactured by Shimadzu Seisakusho Ltd., Kyoto, Japan, and is their model MD1OOP-11PW. ,
