Relapse of multiple myeloma presenting as extramedullary plasmacytomas in multiple organs.

Multiple myeloma is a neoplastic plasma cell disorder. It is characterized by collections of abnormal plasma cells accumulating in the bone marrow, where they interfere with the production of normal blood cells. It usually presents as a multisystemic involvement, whose symptoms and signs vary greatly. Some patients have slowly progressive disease while others have aggressive clinical behavior by extramedullary involvement. In addition to renal failure, anemia, hypercalcemia, lytic bone lesions, and immunodeficiency, it also affects multiple organ system, such as pancreas, adrenal glands, kidney, skin, lung, liver, spleen, lymph nodes, and bone. To raise awareness of the variable presentations of this disease, we report a 53-year-old male patient, with multiple myeloma in his first remission who relapsed with extramedullary plasmacytomas (EMPs) involving multiple organs, such as pancreas, adrenal glands, kidney, skin, lung, liver, spleen, and lymph nodes.

High sensitivity C-reactive protein in spontaneous bacterial peritonitis with nonneutrocytic ascites.

BACKGROUND/AIMS: Diagnosis of spontaneous bacterial peritonitis in cirrhotic ascites is based on a polymorphonuclear leukocyte count of ascitic fluid equal or greater than 250/mm3 in the presence of clinical signs. There is a small number of patients with positive ascitic fluid culture whose polymorphonuclear leukocyte count is less than 250/mm3. In this study, we assessed the diagnostic value of serum high sensitivity C-reactive protein in spontaneous bacterial peritonitis with nonneutrocytic ascites. METHODOLOGY: Patients with decompensated cirrhosis were enrolled in three groups. Group 1: Signs and symptoms of peritonitis plus a polymorphonuclear leukocyte count of ascitic fluid equal or greater than 250/mm3. Group 2: Signs and symptoms of peritonitis, but polymorphonuclear leukocyte count of ascitic fluid less than 250/mm3. Group 3: No signs and symptoms of peritonitis and polymorphonuclear leukocyte count of ascitic fluid less than 250/mm3. Ceftriaxone was started in Groups 1 and 2. Serum level of hsCRP was repeated after the 2nd day of the antibacterial treatment. RESULTS: Mean levels of serum hsCRP were 68.4 mg/dl, 68.3 mg/dl and 6.5 mg/dl in Groups 1, 2 and 3 respectively. Those levels were significantly higher in Groups 1 and 2 compared to Group 3 (p < 0.0001). After the 2nd day of ceftriaxone, serum hsCRP decreased to a mean level of 9.0 mg/dl in Group 1 and to 9.1 mg/dl in Group 2. CONCLUSION: These findings indicate that elevated hsCRP levels may discriminate patients with and without spontaneous bacterial peritonitis even in the presence of nonneutrocytic ascites, and may have utility in the assessment of treatment response.

A case of inflammatory pseudotumor in the spleen.

A case of an inflammatory pseudotumor of the spleen is presented. A 43-year-old woman was hospitalized for a detailed examination due to pancytopenia, which was diagnosed during an examination related to left upper quadrant abdominal pain. Physical examination revealed a 2 to 3 cm splenomegaly. Reticulocyte count was 4% and erythrocyte sedimentation rate was 55 mm/h. No other important findings were noted, except for an evident increase in myeloid series and megakaryocytes (more evident in erythroid series) on bone marrow aspiration and biopsy. Computed tomography (CT) scan revealed splenomegaly and a centrally located hypodense lesion with a 92 X 86 mm axial diameter in the spleen. With a hematologic malignancy prediagnosis, a splenectomy was performed on the patient because of pancytopenia and splenomegaly. An intrasplenic, centrally located, well-limited, capsulated lesion (9.5 x 11 x 10 cm in diameter) was discovered on macroscopic examination of the material. A cellular infiltration area was seen on microscopic examination. The spleen capsule was mildly fibrotically thickened. The lesion that separated from the spleen tissue consisted of diffusely proliferated fusiform fibroblasts, heterogenous inflammatory cells consisting mainly of plasma cells, lymphocytes, sparse neutrophils and vascular elements. No granuloma or multinuclear giant cells were detected. Pancytopenia improved on follow-up. The patient followed up for two years, is now healthy and has no complaints.

Comparison of different risk factors that result in endothelial damage leading to diabetic microangiopathy.

In this study, the effect of different risk factors (hyperglycemia, hypertension, hyperlipidemia, hyperuricemia) on endothelial damage was evaluated in 61 (two of them were type 1; the other patients were type 2) diabetic patients. von Willebrand factor antigen was used as the marker of the endothelial damage. Although there was no significant decrease (P > 0.05) in von Willebrand factor level after regulation of nonregulated diabetes, a significant decrease was determined in nonregulated and hypertensive diabetic patients after improvement of risk factors (P < 0.05). As a result, nonregulated diabetes alone has less effect than nonregulated diabetes plus other risk factors (particularly hypertension) on diabetic angiopathy.

Lessons learned from the Marmara disaster: Time period under the rubble.

OBJECTIVE: To investigate the effect of the time period under the rubble on morbidity and mortality of the crush-syndrome patients after the catastrophic Marmara earthquake that struck northwestern Turkey in August 1999. DESIGN: Observational study. SETTING: Consecutive admissions to emergency and intensive care units of 35 reference hospitals that treated the renal victims. METHODS: Analysis of questionnaires obtained from these hospitals. PATIENTS: A total of 539 of 639 crush-syndrome patients whose time under the rubble was identified in the questionnaires. RESULTS: Mean time under the rubble was 11.7 +/- 14.3 hrs (median, 8 hrs; interquartile range, 6 hrs; range, 0.5-135 hrs). The highest number of patients was entrapped within the 5-8 hrs time stratum, and by the end of 48 hrs, 97% of the victims had been rescued. Nondialyzed victims spent a longer duration under the rubble than dialyzed ones (15.9 +/- 23.1 hrs [median, 7 hrs; interquartile range, 8.5 hrs] vs. 10.3 +/- 9.5 hrs [median, 8 hrs; interquartile range, 6 hrs), p <.001)]. Likewise, in the strata of longer time under the rubble, the percentage of survivors was higher (p =.07). Time under the rubble correlated positively with the number of amputated extremities (p <.001) and admission platelet count (p <.001), and it correlated negatively with admission serum albumin (p <.001). The victims entrapped for >50 hrs (n = 6) were characterized by lower figures of admission blood urea nitrogen (p =.04), serum creatinine (p =.003), hemodialysis sessions, and duration of hemodialysis support (p =.005, for both analyses) compared with victims whose time under the rubble was shorter. CONCLUSION: Rescue efforts should continue at least for 5 days after the disaster. Time under the rubble is not an adverse prognostic indicator of survival or renal dysfunction for the patients of crush syndrome, probably because only the victims with mild or moderate injuries can survive under the rubble for longer durations.
