Epidemiologic, Clinical, and Imaging Findings in Brucellosis Patients with Osteoarticular Involvement

OBJECTIVE The aim of this study was to assess the epidemiologic and clinical features, complications, imaging findings, and outcomes for brucellosis patients with osteoarticular involvement. SUBJECTS AND METHODS This prospective study was performed over 4 years (December 2000-December 2004). The subjects were 251 Turkish patients (age range, 2-77 years) who were diagnosed with brucellosis during that period. Joint sonography, radiography, radionuclide bone scintigraphy, and MRI were performed in all patients with osteoarticular and spinal manifestations. RESULTS The disease was acute in 92 patients (36.7%), subacute in 48 patients (19.1%), and chronic in 111 patients (44.2%). Sonography of the joints showed bursitis in 13 patients (5.2%). Radiography, MRI, and scintigraphy revealed 71 patients (28.3%) with sacroiliitis, 26 (10.4%) with spondylodiskitis, three (1.2%) with acute osteomyelitis, and one (0.4%) with avascular necrosis of the femoral head. All patients received combinations of either two or three antibiotics. Surgery was performed in three patients with spinal instability or radiculopathy. CONCLUSION Brucellosis is endemic to some regions. MRI is the method of choice for diagnosing osteoarticular and spinal complications of human brucellosis, especially during the early phase. It is important to differentiate tuberculous spondylodiskitis from brucellar spondylodiskitis because proper treatment for each of these diseases can prevent complications. The radiologic findings for these two forms of spondylodiskitis are similar, so serologic testing for brucellosis is necessary in such cases.

Clinical Pattern and Abdominal Sonographic Findings in 251 Cases of Brucellosis in Southern Turkey

OBJECTIVE The aim of this study was to report the clinical features, complications, abdominal sonographic findings, and treatment outcomes for a series of brucellosis cases in southern Turkey. SUBJECTS AND METHODS This prospective study involved 251 patients (age range, 2-77 years) who were hospitalized with brucellosis during a 4-year period. Patients were classified as having acute (< 3 months), subacute (3-12 months), or chronic (> 12 months) disease. Physical, laboratory, and abdominal sonographic findings were analyzed. RESULTS The disease was acute in 92 cases (36.7%), subacute in 48 (19.1%), and chronic in 111 (44.2%). Sonographic examination of the abdomen showed enlarged periportal lymph nodes in 23 patients (9.2%), splenomegaly in 21 (8.4%), hepatomegaly in 15 (6%), pleural effusion in 7 (2.8%), splenic abscesses in 4 (1.6%), splenic cysts in 2 (0.8%), acute appendicitis in 2 (0.8%), and acute acalculous cholecystitis in 1 patient (0.4%). The main hematologic and biochemical manifestations were anemia, elevated erythrocyte sedimentation rate, elevated C-reactive protein, and elevated transaminase levels. All patients were treated with combinations of either two or three antibiotics. Surgery was performed in the patients with acute appendicitis, acute cholecystitis, and multiple splenic cysts. CONCLUSION Brucellosis is endemic to Turkey. Sonographic examination is the method of choice for diagnosing abdominal complications of human brucellosis. This disease should be included in the differential diagnosis for any patient with enlarged periportal lymph nodes. The specific treatment regimen and duration of therapy should be based on sites of organ involvement and complications.

Eleven cases of mucormycosis with atypical clinical manifestations in diabetic patients.

OBJECTIVE We retrospectively investigated 11 cases of mucormycosis with atypical clinical features accompanied by diabetes mellitus and discussed clinical features, results of laboratory investigations and radiological examinations and treatment outcomes of each case. METHODS Eleven cases of mucormycosis presenting to our clinic between January 2002 and October 2006 were retrospectively investigated. RESULTS We will present a total of 11 cases of mucormycosis, including 2 cases of mucormycosis with orbital apex syndrome as an initial sign, 2 cases of mucormycosis involving the carotid artery and cavernous sinus with the resultant fatal stroke, 1 case of disseminated mucormycosis with atypical clinical manifestations. Mucormycosis was accompanied by type II diabetes mellitus in five cases, chronic renal failure and type II diabetes mellitus in four cases and type II diabetes mellitus and chronic myelocytic leukemia in two cases. None of them had diabetic ketoacidosis. Only one patient recovered but with sequels: blindness, complete ophthalmoplegia of the right eye. Ten patients died of mucormycosis. CONCLUSION In fact, mucormycosis is a fungal infection which may involve all organs and systems. Mucormycosis must be considered in patients presenting with orbital or preorbital sellulitis, even in the absence of ketoacidosis as in our cases.

Cutaneous manifestations in brucellosis: a prospective study.

Brucellosis remains an important public health problem in Turkey, just as it is in other regions of the world. This study was conducted to determine the types and rates of cutaneous lesions that occur in patients with brucellosis. Brucellosis was diagnosed by standard tube agglutination testing forBrucella antibodies at a titer of 1/160 or higher in the presence of compatible clinical findings. A total of 140 patients who had been given a diagnosis of brucellosis were prospectively observed in the dermatology clinic. Of these patients, 102 (72.9%) were female, with a mean age of 44.11±18.22 y, and 38 (27.1%) were male, with a mean age of 46.44±14.58 y. The duration of symptoms was less than 2 mo (acute) in 75 patients (53.5%), from 2 to 12 mo (subacute) in 30 patients (21.4%), and longer than 12 mo (chronic) in 35 patients (25.0%). Cutaneous findings related to brucellosis were observed in 8 (5.71%) of the 140 cases. Maculopapular eruptions were observed in 2 patients (25%), erythema nodosum-like lesions in 2 (25%), psoriasiform lesions in 1 (12.5%), palmar erythema in 1 (12.5%), malar eruption in 1 (12.5%), and palmar eczema in 1 (12.5%). The investigators concluded that although cutaneous findings encountered in brucellosis are generally not specific to this disease, the presence of these findings may be useful in diagnosing brucellosis in persons who live in, or used to live in, endemic regions.

Evaluation of 28 cases of mucormycosis.

Mucormycosis is a rare but invasive fungal disease with high mortality. The present study aimed to retrospectively investigate the demographic characteristics, as well as the clinical, radiological and laboratory features and the results of treatment, in the patients followed in our hospital because of mucormycosis. The present study retrospectively evaluated 28 cases, which were followed in our hospital because of mucormycosis between January 2002 and July 2013. The clinical form was rhinocerebral in 27 cases (rhinoorbital in 12, nasal in 8 and rhinoorbitocerebral in 7) and disseminated in one case. With regard to predisposing factors, diabetes mellitus (n = 20), haematological malignancy (n = 6) and chronic renal insufficiency (n = 5) were the leading concomitant diseases. Seventeen (61%) of 28 cases showed atypical clinical picture. With regard to the therapeutic outcomes; it was found that 14 (50%) cases died and six cases recovered with sequel. Today, when particularly the prevalence of immunosuppressive diseases and conditions are gradually increasing, the incidence of mucormycosis is also increased. Considering that the majority of our cases had atypical clinical involvement and complications, being familiar with the characteristics of this disease could be life‐saving together with early diagnosis and treatment.

Brucellosis in cases of end-stage renal disease

BACKGROUND Patients with brucellosis frequently present with joint and bone pain. However, brucellosis may be overlooked in patients with end-stage renal disease (ESRD) who undergo dialysis since amyloidosis due to renal osteodystrophy and beta-2 microglobulinaemia may cause bone pain as well. Only four cases of end-stage renal failure accompanied by brucellosis have been reported in the literature. We evaluated clinical and laboratory characteristics and organ involvement of seven brucellosis patients with end-stage renal failure and compared them with brucellosis cases without any renal diseases. METHODS This is a prospective study and involved 158 patients diagnosed with brucellosis. All the patients were divided into two groups: brucellosis patients with ESRD (Group 1) and brucellosis patients without any renal disease (Group 2). RESULTS Group 1 included 7 patients (5 males and 2 females with the mean age 52.1 +/- 14 years) and Group 2 included 151 patients (62 males and 89 females with the mean age 45.4 +/- 16 years). Out of seven patients in Group 1, one had neurobrucellosis, one had paravertebral abscess, one had epidural abscess and one had peripheral arthritis. In addition, one patient in Group 1 with accompanying sickle cell anaemia presented with pain crisis and was diagnosed with brucellosis on admission. Serological tests were negative for brucellosis, but Brucella melitensis was isolated in blood cultures in another patient with accompanying continuous ambulatory peritoneal dialysis. Group 1 more frequently had joint pain and malaise. B. melitensis was isolated in blood cultures in blood taken in the absence of fever in half of the cases in Group 1 positive for B. melitensis in blood cultures on admission. CONCLUSION B. melitensis can be isolated in blood cultures even in the absence of high fever. In fact, in the present study, B. melitensis was isolated in most of the cases without high fever. For this reason, blood cultures should be performed in cases of end-stage renal diseases suspected of having brucellosis although fever is not present. In addition, brucellosis can present various clinical forms in endemic areas, mimics several diseases and can be characterized with severe complications.

Three Cases of Serious Infection Caused by Aerococcus urinae: A Patient with Spontaneous Bacterial Peritonitis and Two Patients with Bacteremia

Aerococcus urinae (A. urinae) is an unusual urinary tract pathogen [1–3], which is also reported in case of endocarditis [1, 3–5], septicemia [6–9], balanitis and phlegmon [1], lymphadenitis [10], and spondylodiscitis [11] in elderly patients with local or systemic predisposing conditions such as neutropenia and prostatic diseases. A. urinae is a grampositive, catalase-negative, microaerophilic, alpha-hemolytic coccus, growing predominately in tetrads and clusters. A. urinae is usually susceptible to b-lactam antibiotics and resistant to sulfonamides and aminoglycosides. Susceptibility to trimethoprim and cotrimoxazole is variable [9]. This paper presents three case reports of the serious A. urinae infections, two associated with bacteremia and to our knowledge the first case recorded of spontaneous bacterial peritonitis (SBP).

Variables determining mortality in patients with Acinetobacter baumannii meningitis/ventriculitis treated with intrathecal colistin.

AIM To examine the variables associated with mortality in patients with Acinetobacter baumannii-related central nervous system infections treated with intrathecal colistin. MATERIALS AND METHODS This multi-centre retrospective case control study included patients from 11 centres in Turkey, as well as cases found during a literature review. Only patients with CNS infections caused by multidrug-resistant or extensively drug-resistant Acinetobacter baumannii treated with intrathecal colistin were included in this study. The variables associated with mortality were determined by dividing the patients into groups who died or survived during hospitalisation, and who died or survived from Acinetobacter meningitis. RESULTS Among the 77 cases enrolled in the study, 35 were found through a literature review and 42 were cases from our centres. Forty-four cases (57.1%) were male and the median age was 48 years (range: 20-78 years). Thirty-seven patients (48%) died during hospitalisation. The variables associated with increased all-cause mortality during hospitalisation included old age (odds ratio, 1.035; 95% confidence interval (CI), 1.004-1.067; p=0.026) and failure to provide cerebrospinal fluid sterilisation (odds ratio, 0.264; 95% confidence interval, 0.097-0.724; p=0.01). There is a trend (P=0.062) towards higher mortality with using of meropenem during meningitis treatment. Fifteen cases (19%) died from meningitis. There were no significant predictors of meningitis-related mortality. CONCLUSIONS The mortality rate for central nervous system infections caused by multidrug-resistant or extensively drug-resistant Acinetobacter baumannii is high. Old age and failure to provide CSF sterilisation are associated with increased mortality during hospitalisation.

Purtscher-like Retinopathy Related to Drug-induced Hypersensitivity Syndrome

Purpose: To report a case with Purtscher-like retinopathy related to drug-induced hypersensitivity syndrome (DIHS). Design: Case report. Methods: A 31-year-old male with fever, macula-papular rash, lymphadenopathy, and hepatitis was hospitalized. Results: Eosinophilic leukocytosis, as well as cotton wool spots around the optic disc, was observed. Viral, bacteriologic, and parasitologic tests and rheumatologic markers were all negative. Given his history of antibiotic use, he was diagnosed as DIHS. On the seventh day he lost consciousness and and on the tenth day he died. Conclusion: Purtscher-like retinopathy might be a sign of DIHS, and should be considered in the differential diagnosis where early intervention is needed.

Visseral leishmaniazisin nadir bir hematolojik komplikasyonu: hemofagositik sendrom

Oz The term “hemophagocytosis” describes the pathologic finding of activated macrophages, engulfing erythrocytes, leukocytes, platelets and their precursor cells. This phenomenon is an important finding in patients with hemophagocytic syndrome. It is a distinct clinical entity characterized by fever, pancytopenia, splenomegaly and hemophagocytosis in bone marrow, liver and lymph nodes. Hemophagocytic syndrome can be classified according to the underlying etiology into either primary (genetic) or secondary (acquired). Severe infections, malignancies, rheumatologic disorders and some metabolic diseases can lead to secondary hemophagocytic syndrome. Infection-associated hemophagocytic syndrome implicating Leishmania is very rare and often difficult to diagnose. Therefore, we aimed to report a young boy with Visceral Leishmaniasis associated hemophagocytic syndrome. Hemofagositoz terimi, aktive makrofajlari, fagosite edilmis
