Actinomycosis is an oppoturnistic infection of actinomyces, which are relatively avirulent endogenous oral commensals. After trauma or infection, they breach the normally protective mucosal barriers to invade adjacent soft tissue structures. Lesions routinely contain other bacteria, the normal resident flora at the site of primary infection, which act synergistically with actinomyces species to provoke this unique infection, which range from an acute suppurative process to a chronic fibrotic process. According to epidemic studies about pelvic actinomycosis, it should be significantly related to IUD(intrauterine device). It is accounted that IUD cause chronic intrauterine infection, tissue injury and act as nucleus for parasitic infestation. Here we present a case of pelvic actinomycosis related to IUD with brief review of the concerned literature.

Hemorrhagic complications associated with aspirin use occur primarily at skin or gastrointestinal sites but can occasionally occur in the central nervous system. In particular, spontaneous spinal epidural hemorrhage (SSEH) associated with aspirin is very rare. We report a case of low-dose (100 mg daily) aspirin-related SSEH that was successfully treated with medical management. Our case indicates that low-dose aspirin could induce SSEH and that conservative treatment with close observation and repeated imaging studies should be considered in cases with neurological improvement or mild deficits.

Subdural empyema is a fulminating, purulent, bacterial infection located between the dura and arachnoidal membrane. Early diagnosis, adequate antibiotic therapy and surgical treatment played important roles in the successful management of subdural empyema. Subdural empyema can develop secondary to sinusitis, otitis media, meningitis, trauma or craniotomy. Subdural empyema in infants commonly develops secondary to infected subdural effusion associated with purulent meningitis. The incidence of this complication of meningitis in infants is approximately 2%. We report a case of subdural empyema concomitant with bilateral subdural effusion, which was successfully treated with surgical intervention and antibiotic therapy.

BACKGROUND: Ultraviolet B (UVB) radiation is a major harmful environmental factor causing cutaneous changes such as sunburn, skin aging and skin cancer. Excessive UVB irradiation induces apoptosis of keratinocytes through several molecular pathways. However, the precise molecular mechanisms have been underinvestigated. OBJECTIVE: The purpose of this study was to investigate expression levels of apoptosis-related genes in UVB- irradiated HaCaT ketratinocyte cell lines. METHODS: Cells were irradiated by UVB at various doses (0, 100, 200 and 400 mJ/cm2). Expression levels of caspases, Bax, Bcl2, and Bcl-XL were confirmed by RT-PCR analysis and western blotting. RESULTS: Expression of cytochrome C was increased followed by activation of caspase-3, 8 and 9 in UVB-irradiated HaCaT cells. Furthermore, the expression of Bcl-XL was decreased from UVB 200 mJ/cm2 and Bcl2 was decreased weakly from UVB 400 mJ/cm2, implying that the expression of Bcl-XL is more sensitive to UVB. Interestingly, the down-regulation of Bcl-XL may be mediated by proteasome dependent pathways. CONCLUSION: Excessive UVB-irradiated HaCaT cells undergo apoptotic cell death following activation of caspases; degradation of Bcl-XL is particularly sensitive to UVB.
