IL-18 is a proinflammatory cytokine produced by macrophages and other cell types present in the kidney during ischemia-reperfusion injury (IRI), but its role in this injury is unknown.

Objectives. This study reviewed the outcome of women attending a breast screening program recalled for assessment of microcalcifications and examined the incidence of a breast carcinoma detected during the following five years in any of the women who were given a benign diagnosis at assessment. Method. A retrospective study consisted of 235 clients attending an Australian BreastScreen program in 2003, who were recalled for investigation of microcalcifications detected on screening mammography. Records for the following five years were available for 168 women in the benign outcome group including those who did not require biopsy at initial assessment. Results. Malignant disease was detected in 26.0% (n = 146) of the women who underwent biopsy. None of the women in the benign outcome group, with available five-year follow-up records, developed a subsequent breast cancer, arising from the calcifications initially recalled in 2003. Conclusions. This study highlights the effectiveness of an Australian screening program in diagnosing malignancy in women with screen detected microcalcification. This has been achieved by correctly determining 38% (n = 235) of the women as benign without the need for biopsy or early recall. A low rate of open surgical biopsies was performed with no cancer diagnoses missed at the time of initial assessment.

We report a case of central nervous system myeloma manifesting as cauda equina nodules, successfully treated with triple intrathecal (IT) chemotherapy, lenalidomide and dexamethasone. After presenting with multiple plasmacytomas which led to a diagnosis of non-secretory myeloma at age 56, the patient underwent multiple episodes of treatment for relapsing myeloma over a 7-year period. In March 2017, he presented with declining gait over a month with bilateral hip flexion weakness, absent lower limb reflexes and dorsal column loss. MRI of the spine revealed multiple enhancing cauda equina nodules at L1–L3. Cerebrospinal fluid (CSF) examination confirmed a clonal plasma cell population and disease was not found elsewhere. He was treated with radiotherapy, IT and intravenous methotrexate and cytarabine. However, repeat lumbar puncture revealed persistent disease. Clearance of CSF plasma cells was achieved with two times a week IT cytarabine, methotrexate and dexamethasone. He was started on lenalidomide and dexamethasone with no evidence of disease progression at 12 months.
