We report the history of a 60-year-old patient with a multiple myeloma and Staphylococcus aureus associated sepsis to whom adenosine in a dose of 6 mg was administered, when a regular, narrow QRS complex tachycardia at a heart rate of 120 beats/minute started. Adenosine led to a complete AV-block and revealed atrial flutter. Atrial flutter waves persisted for about 15 seconds and were followed by atrial and ventricular asystole for about 20 seconds. Repeated nonsustained polymorphic ventricular tachycardias followed and after about 90 seconds sinus rhythm was restored.

For a long time fibrinopeptide A(FPA), fibrinopeptide B(FPB), D-dimer, FM test, serum FDP, and thrombin anti-thrombin complex(TAT) are being used as molecular markers to for sure diagnose hypercoagulable state and thrombus formation. Indeed these molecular markers are very useful for diagnosing thrombus formation, disseminated intravascular coagulation(DIC), and the indicator of treatment of DIC. But these molecular parameters are not enough and difficult for prognosis of the disease or predicting the complication of patients as the most important subject for clinicians. The soluble fibrin monomer-fibrinogen complex (SF) is a complex coupling fibrin monomer and fibrinogen molecules to be formed in the early-activated state of blood coagulation. Thus such a molecular complex is expected to serve as a parameter for the diagnosis of thrombus formation and DIC, in particular its early stage. The aim of the present study is to evaluate a potential usefulness of a newly developed SF test utilizing an SF specific monoclonal antibody (IF-43). We measured SF together with established other parameters in 195 patients with DIC, subclinical DIC/hypercoagulable state, and non-DIC. The diagnosis of DIC was made based on a modified version of the criteria established by the Ministry of Health, Labor and Welfare of Japan. Underlying disease includes leukemia, malignant lymphoma, myelodysplastic syndrome (MDS), multiple injury, giant ovarian tumor, prostatic cancer with multiple bone metastasis, lung cancer, breast cancer with multiple lung and bone metastasis, severe pneumoniae, sepsis, hemophagocytic syndrome (HPS), and rheumatoid arthritis. The SF levels in DIC patients were significantly higher than those in the subclinical DIC/hypercoagulable state, and the non-DIC patients. Receiver operating characteristic (ROC) analysis shows that the specificity and sensitivity of the SF assay appears to be satisfactory. As the level of SF reflects the thrombin generation activity in plasma, it would serve as a strong tool to selectively kick up the state of thrombin generation. These results indicate that the SF could be a specific and reliable parameter for the diagnosis of DIC and contribute to legitimate managements of patients with DIC. The excessive life response to serious clinical insults, such as sepsis, severe pancreatitis, trauma and shock, is called systemic inflammatory response syndrome (SIRS). Once SIRS occurs, people may often die from serious complications such as adult respiratory distress syndrome (ARDS), acute lung injury (ALI), disseminated intravascular coagulation (DIC) and multiple organ failure (MOF). Especially, ALI followed by pneumoniae associated with SIRS could depend on patient's prognosis and life. That is to say, it seems to be urgent for clinicians to make differential diagnosis between Pneumoniae associated with SIRS and Coagulopathy (PASC) and Simple Pneumoniae (SP). Soluble fibrin monomer-fibrinogen complex(SF) is formed in the early-activated state of blood coagulation. Thus such a molecular complex is expected to serve as a parameter for the diagnosis of coagulopathy, in particular its early stage. The aim of the present study is to make differential diagnosis between Pneumoniae associated with SIRS and Coagulopathy (PASC) and Simple Pneumoniae(SP) by using a newly developed SF test utilizing an SF specific monoclonal antibody (IF-43). We measured SF together with established other parameters, hemogram, blood laboratory items in 7 patients with PASC and 17 patients with SP. The diagnosis of Pneumoniae was defined according to the criteria: clinical symptoms abnormal shadow in both Chest X-p and Chest CT, increased level of CRP, number of WBC. The diagnosis of SIRS was based on the criteria established by American College of Chest Physicians (ACCP)/Society of Critical Care Medicine (SCCM) Consensus Conference held in August of 1991 in Northbrook, IL (USA). Underlying disease includes leukemias, malignant lymphoma, myelodysplastic syndrome (MDS), multiple myeloma, idiopathic thrombocytopenia purpura(ITP), multiple injury (bone fracture), cerebral hemorrhage, enterocolitis, Appendicitis, lung cancer, larynx cancer, bronchiolitis obliterans organizing pneumonia(BOOP), chronic obstructive pulmonary disease(COPD), sepsis. The SF levels in PASC patients are significantly higher than those in SP patients (p < 0.001). Otherwise, there is no significant difference of the CRP levels between in PASC group and SP group (p < ns). There is no co-relationship between SF level and D-dimer level. Receiver operating characteristic (ROC) analysis shows that the specificity and sensitivity of the SF assay appears to be quite satisfactory. As the level of SF reflects the thrombin generation activity in plasma, it would serve as a strong tool to selectively kick up the state of thrombin generation. These results indicate that the SF could be a specific and reliable parameter for the diagnosis of PASC and contribute to legitimate managements of patients with PASC.

We report a case of acute fatal exacerbation of chronic hepatitis B in a 50-year-old man with multiple myeloma being treated with thalidomide. The patient had a medical history of chronic hepatitis B and was diagnosed with stage IIIA multiple myeloma. He suffered two episodes of transient transaminitis of unknown origin after successive autologous stem cell transplantations. Spontaneous resolutions of the transaminitis were observed without special management. At that time, PCR of hepatitis B virus (HBV) were all-negative. After 5-months' administration of thalidomide for the second relapse of the multiple myeloma, he suddenly experienced dizziness and jaundice. The level of HBV DNA was 1,641 pg/mL and the serologic tests for other viruses were negative. Despite conventional supportive care, he expired due to septic shock caused by Klebsiella pneumonia. Based on the stable disease status of the multiple myeloma and exclusion of other hepatotoxic agents, it was assumed that the exacerbation of the hepatitis B virus during the thalidomide therapy preceded the bacterial sepsis. With the increased use of thalidomide in cancer treatment, cautious monitoring of the viral burden should be performed in patients with chronic hepatitis B.

A young female with Fisher-Evans' syndrome and a previous melanoma developed acute renal failure with generalized lymphoadenopathy and fever. The appearance of renal lesions is common in the course of several hematological disorders, but is unusual in Fisher-Evans' syndrome. Fisher-Evans' syndrome, defined as Coombs' positive hemolytic anemia and immune thrombocytopenia, is more frequently associated with the other autoimmune diseases, but not with renal involvement. In our case report, having excluded amyloidosis, myeloma, interstitial nephritis and sepsis, the rapid involvement of renal function with enlarged renal size seemed to suggest renal lymphoma. However, the lack of a monoclonal T-lymphocyte population in the renal tissue and peripheral blood, along with a clinical course characterized by a rapid reversibility of acute renal failure made this diagnosis rather an unlikely one. Polyclonal lymphocyte infiltration in a patient with a persistent autoimmune disease made us suspect a hyperimmune reaction. This syndrome is a non-neoplastic proliferation of B-cells involving an exaggeration of lymphocyte transformation. However, the clinical course is progressive and fatal, and can trigger a lymphoproliferative systemic disease. In our patient, two elements led us to suspect it was not a typical hyperimmune syndrome: first, polyclonal lymphocytes had massively infiltrated the kidney and, secondly, the clinical outcome was extremely favorable. Therefore, we were faced with an "atypical" and "singular" hyperimmune reaction with renal involvement, polyclonal proliferation of T-lymphocytes that had exhausted itself over time. Infective or toxic agents or drugs such as cyprofloxacin could have triggered the phenomenon, in the presence of a favorable condition such as Fisher-Evans' syndrome.

Inspite the new informations about the physiology and biochemistry of pain, it remains true that pain is only partially understood. Cancer pain is often experienced as several different types of pain, with combined somatic and neuropathic types the most frequently. If the acute cancer pain does not subside with initial therapy, patients experience pain of more constant nature, the characteristics of wich vary with the cause and the involved sites. Chronic pain related to cancer can be considered as tumor-induced pain, chemotherapy-induced pain, and radiation therapy-induced pain. Certain pain mechanisms are present in cancer patients. These include inflammation due to infection, such as local sepsis or the pain of herpes zoster, and pain due to the obstruction or occlusion of a hollow organ, such as that caused by large bowel in cancer of colon. Pain also is commonly due to destruction of tissue, such as is often seen with bony metastases. Bony metastases also produce pain because of periostal irritation, medullary pressure, and fractures. Pain may be produced by the growth of tumor in a closed area richly supplied with pain receptors (nociceptors). Examples are tumors growing within the capsule of an organ such as the pancreas. Chest pain occurring after tumor of the lung or the mediastinum due to invasion of the pleura. Certain tumors produce characteristic types of pain. For example, back pain is seen with multiple myeloma, and severe shoulder pain and arm pain is seen with Pancoast tumors.

High-dose chemotherapy with autologous stem cell transplantation in patients with newly diagnosed multiple myeloma can prolong survival but is not curative. Maintenance therapy post transplant may prolong the disease-free interval and impact overall survival. We have conducted a phase II pilot study of 28 post transplant myeloma patients treated with a sequential, cycling maintenance regimen. The regimen was designed to include a variety of active myeloma agents chosen for ease of administration to enhance patient compliance and scheduled sequentially to minimize toxicity. The 12-month cycling schedule included dexamethasone (months 1-3); melphalan and prednisone (months 4, 5); cyclophosphamide and prednisone (months 6, 7); alpha-interferon (months 8-10); followed by a drug holiday (months 11, 12). The regimen was generally well tolerated with five patients developing reversible grade III-IV toxicity (diabetes-induced hyperglycemia in four, neutropenia in one). There was one toxic death on study due to non-neutropenic pneumonia and sepsis. Median event-free survival from transplant was 36.9 months (95% CI 23.6 - upper limit not yet reached) with median overall survival not yet reached at a median follow-up of 44 months. This concept of cycling, sequential maintenance with various agents, perhaps including newer biological, targeted agents, warrants further investigation in multiple myeloma.

A 60-year-old male with lumbosacral multiple myeloma received 5100 cGy of external-beam radiation, thalidomide, and Decadron. He subsequently underwent excision of the epidural tumor, decompressive L4, L5, and S1 laminectomies, and bilateral L4-5 and L5-S1 medial facetectomies. The patient developed osteoradionecrosis, cerebrospinal fluid leak, wound infection, and sepsis. Debridement and bilateral V-Y fasciocutaneous advancement flaps failed. Pedicled omental transposition flap through a Petit triangle tunnel was successfully performed. Omental transposition provides a safe option for salvage treatment of irradiated, infected lumbosacral wounds. The plastic and trophic qualities of the omentum make it an excellent choice to fill poorly vascularized wounds. In addition to its immunologic and neoangiogenic properties, the omentum has a dense lymphatic network with tremendous absorptive potential. Its biologic advantages must be weighed against the need for celiotomy and available local options according to circumstances.

In vitro statins induce apoptosis in myeloma and lymphoma cells in a dose-and time-dependent way. In combination with dexamethasone and doxorubicin, statins have a chemo-sensitizing effect. Twenty-eight patients with relapsed myeloma or lymphoma were treated with a dose-escalating regimen of simvastatin for 7 days followed by VAD in myeloma patients and CHOP in lymphoma patients. The maximum tolerated dose was 15 mg/kg/day simvastatin. The most frequently reported side-effects were fatigue, gastrointestinal CTC grade 1-2 and neutropenic fever. The dose-limiting toxicity was neutropenic sepsis and grade 3 gastrointestinal side effects. High-dose simvastatin given immediately prior to chemotherapy is safe and tolerable up to a dose of 15 mg/kg/day.

Multiple myeloma (MM) is a malignant plasma cell tumor that is distributed at multiple sites within the bone marrow compartments. High-dose dexamethasone regimens [including vincristine, doxorubicin, and dexamethasone (VAD) chemotherapy] induce rapid responses, and have resulted in improved survival for many patients when followed by intensive therapy with autologous stem cell support early in the disease course. However, VAD have several disadvantages including the need for an intravenous indwelling catheter, which predisposes patients to catheter-related sepsis and thrombosis; most of the activity of VAD was from high-dose dexamethasone component. We enrolled all patients who fulfilled entire criteria for MM during the period between January 1997 and December 2005. The present study is a descriptive, retrospective, longitudinal, and observational one. The frequency of response (CR, VGPR/NCR, and PR) in the group of thalidomide and dexamethasone was 84.3% (CR 18.75% VGPR/NCR 18.75%, and PR 46.8%) being higher than VAD, 55% (CR 16%, VGPR/NCR 5%, and PR 34%). P = 0.0005. In summary, we conclude Thal/dex is an effective therapy in newly diagnosed MM inducing objective responses in over 84.3%.

Gaucher disease (GD) is a progressive macrophage lipidosis capable of causing disabling and life-threatening complications. Anecdotal experiences suggest that GD may go undiagnosed for many years, leading to severe complications that are preventable or reversible by enzyme replacement therapy (ERT) with imiglucerase. We conducted surveys of patients and Hematology-Oncology specialists to assess the frequency of diagnostic delays. Additionally, we report a series of patients who suffered diagnostic delays and as a result developed disabilities including potentially life-threatening manifestations of GD. Of 136 patients surveyed, the average time from first appearance of GD symptoms to final diagnosis was 48.7 +/- 123.6 months. More than two-thirds were evaluated and managed by a hematologist-oncologist (Hem-Onc). A global survey of 406 Hem-Oncs found that only 20% considered GD in the differential diagnosis for all of its classic symptoms (cytopenia, hepatosplenomegaly, bone pain); the diagnosis considered most likely included leukemia, lymphoma, and multiple myeloma. To illustrate actual consequences of diagnostic delays, we describe 14 patients with GD who suffered from symptoms for up to 10 years before correct diagnosis. Diagnostic delays led to complications that are preventable or reversible with ERT (i.e., avascular necrosis, severe bleeding, chronic bone pain, life-threatening sepsis, pathologic fractures, growth failure, liver pathology). Patients homozygous for N370S mutation in this series were vulnerable to diagnostic delays. In conclusion, prolonged diagnostic delays occur in GD and may result in severe disease manifestations. Our findings suggest that physician education will increase the likelihood of prompt detection of GD and improve its management with ERT with imiglucerase when indicated.
