Primary carcinoma arising in the diverticular wall of the urinary bladder is the most serious complication. The clinical importance is that the carcinoma is difficult to diagnose early, widespread at diagnosis and has poor prognosis. Recently, vigilant studies including bladder mapping reveal premalignant changes and carcinoma in situ adjacent to carcinoma and suggest these premalignant changes evolve to flank carcinoma. For early detection and improving the prognosis, be required through cystoscopic examination including diverticular wall and multiple punch biopsies as well as consecutive urine cytologic examination. Author report two cases of primary carcinoma arising in bladder diverticulum. One revealed carcinoma in situ accompanied with adjacent atypical hyperplasia in diverticula mucosa incidentally found at the pathologic examination on the divertiuclectomy specimen. The other case showed invasive transitional cell carcinoma(Grade IV, Stage D) of diverticulum. The two cases described suggest that vesical diverticulum should be removed into to with a good amount of surrounding bladder wall.

Korea had been one of hyperendemic countries of human parasitic infections until 1970s.In 1966, the Law for the Prevention of Parasitic Diseases was enacted, and the nationwide anti-parasitic control program began in 1969. The initiation of the national program was supported financially by Japan. The program included screening of whole students in Korea and treatment of all egg positive cases twice a year, and ended in 1995. In addition to student program, deworming campaign was run in the community, and 8 national status surveys were implemented from 1971 to 2012. Whole helminth egg positive rate was 84.3% in 1971 and decreased to 2.6% in 2012. Ascaris and other intestinal nematodes, Paragonimus, Taenia, and intestinal protozoa had decreased significantly throughout the country, but Clonorchis sinensis and intestinal trematodes are still prevalent locally in endemic areas. Lymphatic filariasis had been endemic in Jeju-do and other southern islands but elimination was endorsed in 2008. The control of parasitic infection in Korea was successful with statistical prevalence data, which can be a benchmarking model. In conclusion, the successful control in Korea could be achieved by social agreement of the priority, professional guidelines and systematic approach with good anthelminthics supply, and simultaneous economic growth.

Myiasis is the infestation of any part of the body by Diptera larvae. It is the fourth most common travel-associated skin disease and cutaneous myiasis is the most frequently encountered clinical form. Furuncular lesions may result when the skin is affected. Cutaneous myiasis caused by Cordylobia anthropophaga has been endemic in the sub-Saharan African region for more than 135 years. There have been some reported cases from non-endemic regions, and yet C. anthropophaga infestations are rarely acquired outside of Africa. We report here a rare case of furuncular cutaneous myaisis by C. anthropophaga in a German patient who came to Korea after a three-week trip to Benin.

Objective To establish and evaluate criteria applied to review of complete blood counts (CBC)and differential results from automated hematology analyzers.Methods Temporary criteria were established by using alarm system of XE-2100 automated hematology analyzer and by consulting the 41 suggested rides of international consensus group.2 795 out-and in-patient samples were run as clinical samples.Stained blood films were prepared and manual differential with smear review were performed on all samples.Statistical analysis was done for each temporary rule and instrument flag which indicated abnormal cell quantity and morphology.Results Of all rules,instrument flags of ‘Immature Gran/Left Shift?’, ‘ Atypical Lympho?’and‘NRBC(nucleated red blood cell)?’showed most frequent false positive and false negative instrument flag.Evaluation on rnles about cell quantity change showed false positive and false negative rates were both low.Results of morphology evaluation showed that true positive rate was 17.44%, false positive rate was 15.82%,true negative rate was 63.49%,false negative rate was 3.25%.‘ Atypical Lymphocyte?’,‘Immature Gran?’and‘blast?’were the most frequent false positive flags.According to those results and clinicians opinions,our hematology review criteria for action following automated CBC and leukocytes differential was established.Conclusions The hematology review criteria have high true positive rate and low false negative rate.To clinical hematology laboratory using automated hematology analyzer,new criteria can reduce work load,bring lower false negative rate and higher work efficiency.

The wheeled mobile robot(WMR)was introduced in terms of concept,development route and application progress in medical service support in the world.The advantages and disadvantages of the WMRs from some countries were analyzed,and the key technologies of WMR were described.It's pointed out the WMR would be enhanced in obstacle-crossing ability,battlefield sensing and information interaction and endurance.[Chinese Medical Equipment Journal,2024,45(3):86-94]

OBJECTIVE: To investigate whether frozen-thawed testicular sperm obtained from men with azoospermia could serve as an efficacious sperm source for intracytoplasmic sperm injection (ICSI) by comparing to the results of ICSI using fresh testicular sperm. METHODS: From January 1997 to March 1999, 41 patients with azoospermia who underwent ICSIs using fresh and/or frozen-thawed testicular sperm were included in the study. In 23 patients of 41, fresh testicular sperm was left after ICSI and therefore remaining testicular sperm was frozen and frozen testicular sperm was used in next ICSI cycles. The results of ICSI were compared in frozen-thawed testicular sperm (frozen-thawed group, 30 cycles) versus fresh testicular sperm (fresh group, 39 cycles). RESULTS: The number of fertilized oocytes, grade I/II embryos, fertilization rate, clinical pregnancy rate were comparable in the frozen-thawed and fresh groups. There were also no differences in the miscarriage rate and multiple pregnancy rate between the two groups. In patient group with obstructive azoospermia, there were no significant differences in the number of fertilized oocytes, grade I/II embryos, fertilization rate, clinical pregnancy rate between the two groups. In patient group with non-obstructive azoospermia, all parameters of results of ICSI were comparable in both groups. In each non-obstructive azoospermic patient group with mixed motile/immotile sperm and patient group with only immotile sperm, there were also no significant differences in the number of fertilized oocytes, grade I/II embryos, fertilization rate, clinical pregnancy rate between the frozen-thawed and fresh groups. CONCLUSION: Our data demonstrate that using frozen-thawed and fresh testicular sperm gives rise to comparable results after ICSI irrespective of the status of sperm in patients with obstructive or non-obstructive azoospermia.
