RESUMEN
Catatonia is a psychiatric emergency in schizophrenia that often leads to excessive activation of the sympathetic nervous system. Urinary retention in catatonia is often underestimated but has potentially detrimental consequences. Herein, we present the case of a woman in her 40s with schizophrenia treated for catatonia during a relapse. When treated as an inpatient, the patient suddenly complained of severe abdominal pain. Computed tomography revealed a spontaneous rupture of the posterior wall of the bladder, requiring emergency repair surgery in the urology department. The patient was readmitted to our hospital following surgery and ultimately discharged 1 month later. Bladder rupture is life-threatening, and delayed diagnosis and treatment can be fatal. This case report serves as a warning that psychiatrists should not overlook urinary retention in patients with catatonia and should consider bladder rupture in the differential diagnosis when these patients have abdominal pain.

We surveyed the expression of 557 cancer-related genes in 15 cases of well-differentiated OSCC by cDNA microarray analysis. To identify potential biomarkers for lymph node metastasis, all microarray data were compared by the Mann-Whitney test and the significance analysis of microarrays between OSCCs with and those without lymph node metastasis. The tissues of OSCCs with lymph node metastasis exhibited increased expression levels of MMP-1, MMP-3, uPA, integrin-alpha3, paxillin, tenascin C and IL-6 transcripts. All of these genes were included in common clusters on the Cluster/TreeView analysis, implying that functional gene groups of proteolytic enzymes and integrin-related molecules are involved in cervical lymph node metastasis. The results of RTQ-PCR for differentially expressed genes were in accord with those of cDNA microarray analyses, suggesting that the data obtained by microarray gene expression analyses were valid. Consistent with cooperative expression patterns, immunohistochemical analyses demonstrated that products of MMP-1, MMP-3 and uPA were colocalized to components of the neoplastic stroma, particularly mononuclear inflammatory cells with well-developed eosinophilic cytoplasm. Our results suggest that expression levels of molecules involved in tissue remodeling and cell-ECM adhesion, especially MMP-1 and integrin-alpha3, can provide an accurate biomarker system for predicting the risk of cervical lymph node metastasis in OSCC.
