Objective : To find the effective means to detect adverse drug reactions (ADRs) from hospital information system, three data sources, i.e. diagnosis data (Dx), laboratory data (Lab), and prescription data (Rx), are compared in diuretics induced hyperuricemia and/or gout (H/G).
Design : Retrospective cohort study.
Methods : Cohort entry period was three months. Hypertensive outpatients who already had H/G prior to that period were excluded. Then, they were surveyed for 9 months. The patients using diuretics were separated into two groups, i.e. Thiazide-treated group, and Loop-treated group.
Controls were randomly selected from non-diuretic-treated hypertensive outpatients matched to each diuretic group by age and sex. Signals of ADRs were the new prescription of drugs employed in the treatment of H/G from Rx, abnormal serum uric acid level from Lab, and diagnosis of H/G from Dx. The interrelationship of them were examined by the Venn diagram and scatter plot. Finally the incidence of ADRs detected by the above signals and relative risks were calculated and compared. Moreover, prevalence of renal disease in each group was surveyed to examine the possibility that renal disease caused H/G.
Results : Eighteen patients in 240 outpatients treated with Thiazide diuretics and 70 patients in 523 outpatients treated with Loop diuretics were found having developed H/G from Dx, Lab, and/or Rx data sources. More than 90% of total patients were detected from Lab while, a few patients were identified from Dx and Rx. It was rare and coincidental that the three data sources agreed with one another.
The risk of Loop diuretics is approximately twice that of Thiazide diuretics. The incidence and risk of H/G in diuretics estimated in the current study were compatible with the prior report. However, the prevalence of renal disease were high (though not statistically significant) in Loop-treated group so that we possibly overestimated the risk of it.
Conclusion : The order of three data sources, arranged according to the number of ADR signals detected, was Lab, Rx, and Dx. It may be possible to assess the risk of ADR even by Lab only. If Lab is not available, Rx and Dx are useful provided that more subjects and longer research period are involved. However it is necessary to combine three data sources, Dx, Lab, and Rx to detect as many suspected adverse events as possible when using the present clinical database.

The human gut microbiota changes under the influence of environmental and genetic factors, affecting human health. Extensive studies have revealed that the gut microbiome is closely associated with many non-intestinal diseases. Among these, the influence of the gut microbiome on cancer biology and the efficacy of cancer therapy has attracted much attention. Prostate cancer cells are affected by direct contact with the microbiota of local tissues and urine, and a relationship between prostate cancer cells and the gut microbiota has been suggested. In the human gut microbiota, bacterial composition differs depending on prostate cancer characteristics, such as histological grade and castration resistance. Moreover, the involvement of several intestinal bacteria in testosterone metabolism has been demonstrated, suggesting that they may affect prostate cancer progression and treatment through this mechanism. Basic research indicates that the gut microbiome also plays an important role in the underlying biology of prostate cancer through multiple mechanisms owing to the activity of microbial-derived metabolites and components. In this review, we describe the evidence surrounding the emerging relationship between the gut microbiome and prostate cancer, termed the “gut-prostate axis.”

BACKGROUND: The canonical Wnt/β-catenin signaling pathway is a fundamental regulatory system involved in various biological events. ICG-001 selectively blocks the interaction of β-catenin with its transcriptional co-activator cyclic AMP response element-binding protein (CBP). Recent studies have provided convincing evidence of the inhibitory effects of ICG-001 on Wnt-driven disease models, such as organ fibrosis, cancer, acute lymphoblastic leukemia, and asthma. However, the effects of ICG-001 in atopic dermatitis (AD) have not been investigated. OBJECTIVE: To investigate whether β-catenin/CBP-dependent signaling was contributed in the pathogenesis of AD and ICG-001 could be a therapeutic agent for AD. METHODS: We examined the effects of ICG-001 in an AD-like murine model generated by repeated topical application of the hapten, oxazolone (Ox). ICG-001 or vehicle alone was injected intraperitoneally every day during the development of AD-like dermatitis arising from once-daily Ox treatment. RESULTS: Ox-induced AD-like dermatitis characterized by increases in transepidermal water loss, epidermal thickness, dermal thickness accompanied by increased myofibroblast and mast cell counts, and serum levels of thymic stromal lymphopoietin and thymus and activation-regulated chemokine, and decreases in stratum corneum hydration, were virtually normalized by the treatment with ICG-001. Elevated serum levels of periostin tended to be downregulated, without statistical significance. CONCLUSION: These results suggest that β-catenin/CBP-dependent signaling might be involved in the pathogenesis of AD and could be a therapeutic target.

In 1991, the committee on postgraduate clinical training proposed revised behavioral objectives for basic clinical training in the initial two years. We present here a model for a clinical training program that should enable most residents to attain these objectives within two years.
The program begins with orientation for 1-2 weeks, including a workshop on team care, and nursing practice.
Basic clinical skills for primary care and emergency managements should be learned by experience during rotations through various clinical specialities. All staff members, even senior residents, should participate in teaching beginning residents in hospitals.

We report the case of a 46-year-old Chinese male patient who visited our clinic complaining of infertility. Semen analysis revealed azoospermia, and azoospermia factor c region partial deletion (b1/b3) was detected using Y chromosome microdeletion analysis. Testicular sperm extraction was performed after genetic counseling. The bilateral ductus deferens and a portion of the epididymis were absent, whereas the remaining epididymis was expanded. Motile intratesticular spermatozoa were successfully extracted from the seminiferous tubule. On histopathology, nearly complete spermatogenesis was confirmed in almost every seminiferous tubule. To our knowledge, this is the first case report of b1/b3 deletion with a congenital bilateral absence of the vas deferens and almost normal spermatogenesis.

Onco-testicular sperm extraction is used to preserve fertility in patients with bilateral testicular tumors and azoospermia. We report the case of a testicular tumor in the solitary testis of a patient who had previously undergone successful contralateral orchiectomy and whose sperm was preserved by onco-testicular sperm extraction. A 35-year-old patient presented with swelling of his right scrotum that had lasted for 1 month. His medical history included a contralateral orchiectomy during childhood. Ultrasonography revealed a mosaic echoic area in his scrotum, suggesting a testicular tumor. The lesion was palpated within the normal testicular tissue along its edge and semen analysis showed azoospermia. Radical inguinal orchiectomy and onco-testicular sperm extraction were performed simultaneously. Motile spermatozoa were extracted from normal seminiferous tubules under microscopy and were frozen. Eventual intracytoplasmic sperm injection using the frozen spermatozoa is planned. Onco-testicular sperm extraction is an important fertility preservation method in patients with bilateral testicular tumors or a history of a previous contralateral orchiectomy.
