Richter's transformation; the cause of fever of unknown origin in a case with chronic lymphocytic leukemia

Chronic lymphocytic leukemia (CLL) is the most common leukemia in many countries. Infections are the most common causes of morbidity and mortality; lymphoid cell dysfunction and neutropenia associated with chemotherapy are main predisposing conditions for infection. For this reason infectious conditions must be excluded in a case with CLL and fever. Richter's transformation (RT) is a kind of lymphoma that is a rare condition in CLL cases Fever of unknown origin is a rare finding in Richter's transformation (RT) but it has been reported as anecdotal reports. Here a case with RT as the cause of fever in a case with CLL was reported and literature was reviewed

A case of myocarditis mimicking acute coronary syndrome associated with H1N1 influenza A virus infection

PubMedID: 21248460Myocarditis due to H1N1 influenza infection has not been previously described. We report on a case of acute fulminant myocarditis caused by H1N1 influenza A virus infection that mimicked acute coronary syndrome. A 50-year-old man was admitted with dyspnea, fever, cough, vomiting, and atypical chest pain of three-day history. His body temperature, pulse rate, and blood pressure were 39.2 °C, 115 beats/min, and 80/40 mmHg, respectively. Electrocardiography showed sinus tachycardia, 1-mm ST-segment elevation, and absence of R wave progression in anterior leads, and ST depression in anterolateral leads. The chest radiogram revealed diffuse bilateral alveolar infiltrates. Cardiac enzymes were elevated. Despite treatment with aspirin, clopidogrel, low-molecular weight heparin, metoprolol, and an ACE inhibitor, he developed hemodynamic instability on the first day of admission. Echocardiographic examination showed anteroseptal, apical, and lateral wall hypokinesia, left ventricular diastolic dysfunction, and dilatation of all the chambers. There was no abnormal finding on coronary angiography. The diagnosis was considered to be myocarditis; thus, anticoagulant and antiaggregant therapies were discontinued, and empirical broad-spectrum antimicrobial treatment was initiated together with antiviral oseltamivir (2x75 mg/day). The patient's clinical condition significantly improved. Nasopharyngeal samples were positive for H1N1 influenza A virus. He was discharged on the 15th in good medical condition

A clinical review of 40 cases with tuberculous spondylitis in adults

The purpose of this clinical review was to review clinical presentations, laboratory, and radiologic findings and difficulties on management of tuberculous spondylitis from a series of 40 cases. We carried out a retrospective analysis of 40 adult patients (50% male) with tuberculous spondylitis between January 1997 and December 2003. Infection was diagnosed in patients having a presentation compatible with characteristic histologic and/or microbiologic evidence of tuberculous spondylitis and diagnostic radiographic features, or following adequate response to antituberculous therapy with highly suggestive imaging features. Outcome was assessed according to clinical, radiologic, and laboratory criteria. Mean age was 44.7±19 years. Thirty percent of patients had a history of contact with a patient having active pulmonary tuberculosis. The most frequent symptom and sign were back pain (92.5%) and, spinal tenderness (55%). Magnetic resonance imaging was found to be the most helpful technique for diagnosis. Lumbar spine was the most common affected region (82.5%). Thirty (75%) patients had paraspinal abscess and, 4 (10%) had concomitant sacroiliitis. Spinal biopsy had a yield of 76.5%, 52.9%, and 47% granulomas, positive culture, and acid-fast smear, respectively. Resistance to antituberculous drugs was 44.4%. Although medical treatment alone was given in 15% cases, 85% required additional surgical intervention. The mean duration of therapy was 12±12 months. The improvement without sequela was 77.5% of the patients. In developing countries, diagnostic delay in tuberculous spondylitis is still common and disastrous. Bacteriologic confirmation and susceptibility testing should be achievable in all adult cases. © 2006 Lippincott Williams & Wilkins, Inc

Invasive device-associated nosocomial infections of a teaching hospital in Turkey; four years' experience [Türkiye'deki bir hastanenin invazif araç ilişkili enfeksiyon hızları; dört yıllık deneyim]

Aim: To determine our setting's IDAI rates, infecting microorganisms, and their resistance patterns to achieve standardization and make comparisons among other Turkish and developed country hospitals all over the world. Materials and methods: The numbers of total patient days, ventilator days, central catheter days and, urinary catheter days in the ICUs were recorded and IDAI rates were calculated. Clinical specimens were obtained from patients, cultivated at appropriate culture media, and infecting microorganisms and resistance patterns were determined. Results: Totally 1450 invasive device-associated infection episodes were determined (16.4% of patients) with a rate of 21.12/1000 days. Ventilator associated pneumonia rate was 22.05/1000 ventilator days and most common microorganism was Acinetobacter baumannii. Central catheter associated blood stream infection rate was 9.14/1000 central catheter days and the most common infecting organism was A. baumannii. Catheter associated urinary infection rate was 10.12/1000 urinary catheter days and the most common pathogen was Candida species. MRSA rate decreased from 89.6% in 2006 to 61.8% in 2009 (P < 0.001). ESBL production rates were between 70.7% and 45.6% in Escherichia coli and 66.7% and 55.9% in Klebsiella pneumoniae isolates. Vancomycin resistance among Enterococci was between 34.3% and 21.7% in these years. Conclusion: Our hospital infection rates were found to be similar to those of country data but higher than those in developed nations. Considering the high infection and resistance rates to most of the available antibiotics, it is highly urgent that infection control measures be taken and more effective antibiotic control policies be adopted. © TÜBİTAK
