Emphysematous cystitis is a rare complication of lower urinary tract infection whose prognosis is conditioned by the delay in treatment. The predisposition of diabetic patients to urinary infections caused by gas-producing bacteria is considered one of the most common factors in the occurrence of emphysematous cystitis. The currently recommended diagnostic test is CT scanning, which has definite value in assessing gas accumulation in the bladder wall and lumen. The authors report the observations of two patients aged 68 and 80 who were treated for emphysematous cystitis complicating diabetes mellitus. The evolution was favorable under treatment with antibiotic therapy, insulin therapy and bladder drainage.

Introduction: Testicular cancer accounts for 5% of urological tumors, predominantly affecting young men. The aim of our study was to report the diagnostic and evolutionary aspects of testicular cancer cases treated in our center. Patients and Methods: A retrospective study conducted over a 15-year period involving 12 patients treated for testicular cancer at the University Hospital of Brazzaville. Results: The median age was 31 years (range 11 to 49 years), with a median consultation delay of 10.6 months (range 3 to 27 months). Scrotal mass was the most common reason for consultation. Cancer was bilateral in two patients. Two patients were admitted with metastatic disease. Histopathological examination favored germ cell tumors in 7 cases, two cases of non-Hodgkin’s malignant lymphoma, and one case of epididymo-testicular adenocarcinoma. Adjuvant chemotherapy resulted in complete remission in patients with germ cell tumors. However, neoadjuvant chemotherapy was not effective in patients admitted with advanced-stage disease. Conclusion: Testicular cancer is a rare condition that is curable in the majority of cases, but its management is often complicated in our setting due to delayed diagnosis caused by taboos surrounding genital organ pathologies.

Based on the empirical analysis of data contained in the International Software Benchmarking Standards Group （ISBSG） repository, this paper presents software engineering project duration models based on project effort. Duration models are built for the entire dataset and for subsets of projects developed for personal computer, mid-range and mainframe platforms. Duration models are also constructed for projects requiring fewer than 400 person-hours of effort and for projects requiring more than 400 person-hours of effort. The usefulness of adding the maximum number of assigned resources as a second independent variable to explain duration is also analyzed. The opportunity to build duration models directly from project functional size in function points is investigated as well.

Checkpoint blockade therapy and adoptive therapy with engineered human immune effector cells are paradigm-changing innovations that have already revolutionized the treatment of cancer for which critical advances have been achieved with CTLA-4 or PD-1/PD-L1 inhibitors and with chimeric antigen receptor T(CAR-T)cells,*** paradigm-changing innovations reflect the intricate relationships between inflammatory and immunological events and the pathobiology of *** is,for example,described as“wounds that do not heal”,and deeper exploration of the correspondence between the molecular events that occur in cancer and those that occur in chronic infection constitutes a rich ground for fundamental discoveries.
