ABSTRACT

BACKGROUND: Crush Syndrome is a major cause of morbidity and mortality following large-scale catastrophic earthquakes. Since there are no randomized controlled studies on Crush Syndrome, knowledge on this subject is limited to expert experience. The primary objective is to analyze the epidemiological and demographic characteristics, clinical outcomes, and mortality factors of earthquake victims after the Pazarcik and Elbistan earthquakes on February 6, 2023. METHODS: This cross-sectional and observational retrospective study evaluated 610 earthquake victims who presented to our center between February 6 and April 30, 2023. Among these patients, 128 with Crush Syndrome were included in the study. Patient information was gathered from hospital records during their stay and from national registries upon referral. The primary outcome was to identify risk factors for mortality. Demographic and laboratory data were analyzed by acute kidney injury (AKI) stages; mortality-affecting factors were identified through regression analysis. RESULTS: Of the 128 Crush Syndrome patients (100 adults, 28 children), 64 were female. The AKI rate was 32.8%. Among patients with AKI, the frequency of hemodialysis requirement was 69%, and the mortality rate was 14.2%. The overall mortality rate for patients with Crush Syndrome was 4.6%, compared to 3.9% (19/482) in earthquake victims without Crush Syndrome (p=0.705). Notably, low systolic blood pressure at admission was the only factor significantly affecting mortality in Crush Syndrome patients (Hazard Ratio [HR]: 1.088, p=0.021, 95% Confidence Interval [CI]). CONCLUSION: Our study highlights low systolic blood pressure upon admission as a significant risk factor for increased mortality in Crush Syndrome patients. This finding may contribute to the literature by emphasizing the importance of monitoring blood pressure under rubble and administering more aggressive fluid therapy to patients with low systolic blood pressure.

ABSTRACT

Intravesical bacillus Calmette-Guérin (BCG) is used for urothelial carcinoma. Systemic side effects are rare and commonly include organ involvement but rarely include bone marrow. We describe a patient who had received intravesical BCG and presented shortly afterwards with constitutional symptoms. Initial work-up revealed pancytopenia and immune haemolysis. He was presumptively diagnosed with systemic BCG infection and secondary warm autoimmune haemolytic anaemia. Isoniazid, rifampin and ethambutol was started. The bone marrow biopsy revealed granulomas. Within 6 weeks of treatment, the patient's clinic and laboratory results were dramatically improved. A high level of suspicion is crucial for diagnosis and treatment. LEARNING POINTS: Systemic bacillus Calmette-Guérin (BCG) infection following intravesical BCG instillation is a rare but serious consequence. A high level of suspicion and scrutiny of history is of paramount importance for diagnosis.Autoimmune haemolytic anaemia secondary to systemic BCG infection is even rarer.Autoimmune haemolytic anaemia resolution was in parallel with improvement in systemic BCG infection.

ABSTRACT

OBJECTIVES: It is unclear whether patients with oral foci of infection should be approved for hematopoietic stem cell transplant with or without posttransplant cyclophosphamide. We compared the presence of oral foci of infection status on the effects of various conditioning regimens for such patients. MATERIALS AND METHODS: Three groups were classified as autologous (carmustine-etoposide-cytarabinemelphalan, mitoxantrone-melphalan, and melphalan 200 mg/m² groups; n = 502 patients), and 6 groups were classified as allogeneic (busulfan-fludarabinerabbit anti-T-lymphocyte globulin, busulfanfludarabine-posttransplant cyclophosphamide, fludarabine-cyclophosphamide-anti-T-lymphocyte globulin, busulfan-fludarabine-anti-T-lymphocyte globulin-posttransplant cyclophosphamide, total body irradiation-posttransplant cyclophosphamide, and other; n = 428 patients). Data were collected from a database that met international accreditation requirements. We evaluated dental radiological findings and calculated interobserver reliability. RESULTS: Oral foci of infections increased febrile neutropenia and bacterial infection frequencies in both groups but only increased mucositis frequency in patients with allogeneic treatment. The frequencies of oral foci of infection-related complications were similar in both the autologous and allogeneic groups. Rate of graft-versus-host disease was not affected by oral foci of infection status. Periodontitis/cysts and periapical lesions increased the risk of infections at day 100 in the mitoxantrone-melphalan group versus the melphalan 200 mg/m² group. We observed no differences among the autologous transplant groups in terms of early mortality. Similarly, no differences in early mortality were observed among the allogeneic groups. CONCLUSIONS: Transplant is a valid option in patients with oral foci of infections undergoing various autologous and allogeneic transplant protocols when time is of the essence, even at myeloablative dose intensities.

ABSTRACT

OBJECTIVES: The adoption of international quality and accreditation standards is important for the success of transplant centers. Guidelines from the Joint Accreditation Committee ISCT-Europe and EBMT (JACIE) have enabled quality management of the operations of clinical units of cellular therapy centers, including cell collection and processing, thus minimizing errors and adverse events. COVID-19 has had significant implications for immunocompromised patients, particularly hematopoietic stem cell transplant recipients, as well as their donors and caregivers. Here, we retrospectively examined measures, taken in our transplant center in Turkey during the pandemic period between March 2020 and October 2021, to investigate how JACIE accreditation has affected patient, donor, product, and employee safety. MATERIALS AND METHODS: We analyzed data on transplant activity, as well as donor, patient, product, and employee safety, during the pandemic in 3 separate 6- month periods. The measures were analyzed starting from March 2020, when the first COVID-19 case was seen in Turkey. RESULTS: Since the beginning of the pandemic, 140 patients have undergone stem cell transplant in our center. Stem cell transplant was delayed in 22 patients because of the pandemic. Transplant was also postponed due to COVID-19 positivity in 6 patients, and 2 patients died due to COVID-19 infection during the transplant process. Unrelated donor activity continued to be performed safely throughout this period. COVID- 19 infection developed in 12 of the 52 personnel working in the bone marrow transplant unit, one of whom needed intensive care due to severe pneumonia. In terms of quality management activities, the impact of the pandemic was greatest during the first month. CONCLUSIONS: Results from our retrospective study examining the impact of JACIE accreditation in a stem cell transplant center during the COVID-19 pandemic showed that, when national and international guidelines are followed, JACIE accreditation can facilitate adaptation to changing conditions in transplant centers.

ABSTRACT

Objective: The present study aims to define the characteristics of the necrotizing fasciitis (NF) cases followed at our hospital and to compare our results with the literature. Materials and Methods: In this study, NF cases followed and treated at our hospital from January 2005 to April 2019 were evaluated retrospectively. Results: A total of 85 cases of NF were included in the study. Of the cases, 33 (39%) were female and the median age was 59.8±13.1 years (range: 26-92 years). Diabetes mellitus (DM) (56%) was the most prevalent comorbid condition. Extremities were the most frequently involved field found in 41 (48%) of the cases followed by Fournier's gangrene found in 34 (40%) of the cases. All of the cases had undergone surgical intervention (debridement and/or amputation) and received broad-spectrum antibiotic therapy. Laboratory risk indicator for necrotizing fasciitis (LRINEC) score was calculated for 60 cases, and it was 6 or higher in 78% of them. Nineteen (22%) of 85 cases had died. Conclusion: Necrotizing fasciitis affects generally older male patients with DM. In NF cases to avoid the higher risk of mortality, the removal of necrotic tissue via surgical procedure together with antimicrobial therapy is required urgently; therefore, it is very important to differentiate NF from soft tissue infections as soon as possible. As the LRINEC score predicted NF among nearly 80% of our patients, this score could be used as an early diagnostic tool of NF. Level of Evidence: Level IV, case series.

ABSTRACT

Globally 364102 healthcare professionals have been infected with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) and 1253 of them died until 15 January 2021. Healthcare professionals serving at the forefront of combating the pandemic are in the high risk group. In our country, the data about coronavirus-2019 (COVID-19) among healthcare professionals are limited. The aim of this study was to investigate the anti-SARS-CoV-2 IgG seroprevalence in healthcare professionals, to evaluate the risks they encountered during work, and to examine their relationships with antibody positivity. A total of 572 healthcare professionals serving in various units of our hospital participated in our study and the presence of anti-nucleocapsid IgG was investigated by chemiluminescent microparticle immunoassay (SARS-CoV-2 IgG test, Abbott Laboratories Diagnostics, USA) method in serum samples collected between May 18, 2020 and June 30, 2020. The demographic characteristics, medical history, work conditions, medical procedures performed and possible risk factors were questioned with a questionnaire form. The average age of the participants was 33.5 ± 9.2 (19-61) years, and 62.9% (360/572) of them were women. In our study, the anti-SARS-CoV-2 IgG seroprevalence was 3.7% (21/572). The association of the antibody positivity with age, gender and occupational status was not statistically significant (p> 0.05). Comorbid diseases which were significantly higher in seropositive healthcare professionals were hypertension (19%) and diabetes mellitus (14.3%) (p<0.05). It was observed that antibody positivity was significantly higher in healthcare professionals working in high (52.4%) and medium risk (33.3%) areas, those who treat and/or examine patients with suspicious or positive COVID-19 (66.7%) and those who spend more than 30 minutes in COVID-19 patient rooms (76%) (p<0.05). The symptoms associated with seropositivity in healthcare workers with a history of symptoms (46%) were loss of smell (23.5%), loss of taste (20.0%) and respiratory distress (16.7%) (p<0.05). It was observed that the probability of being infected with SARS-CoV-2 increased 12 times if there was a colleague with COVID-19 in the hospital, four times if there was a patient in the house/lodging and six times if there was an infected person in the social environment (p<0.05). The rate of those who had the flu vaccine among the participants was 10.8% (62/572) and 9.7% of them were found to be anti-SARS-CoV-2 IgG positive (p<0.05, 95% CI= 1.31-9.48). The seropositivity was significantly higher in non-smokers (4.8 %) compared to smokers (0.0%) (p<0.05). In our study, it was determined that the rate of seropositivity was 12 times higher in healthcare professionals who stated that they received hydroxychloroquine prophylaxis due to risky contact compared to those who did not receive prophylaxis (p<0.05, 95% CI= 4.11-40.64). The ratio of the personnel who answered "always" to the frequency of wearing gloves, masks, goggles/face shields and overalls was 85.7%, 96.9%, 62.1% and 65.4%, respectively. In conclusion, regular and large-scale seroepidemiological screening of healthcare professionals in the COVID-19 pandemic can contribute to the control of the pandemic by providing a better understanding of transmission dynamics and risk factors.

ABSTRACT

It is highly expected that COVID-19 infection will have devastating consequences in sickle cell disease (SCD) patients due to endothelial activation and decreased tissue and organ reserve as a result of microvascular ischemia and continuous inflammation. In this study, we aimed to compare the clinical course of COVID-19 in adult SCD patients under the organ injury mitigation and clinical care improvement program (BASCARE) with healthcare professionals without significant comorbid conditions. The study was planned as a retrospective, multicenter and cross-sectional study. Thirty-nine SCD patients, ages 18 to 64 years, and 121 healthcare professionals, ages 21 to 53, were included in the study. The data were collected from the Electronic Health Recording System of PRANA, where SCD patients under the BASCARE program had been registered. The data of other patients were collected from the Electronic Hospital Data Recording System and patient files. In the SCD group, the crude incidence of COVID-19 was 9%, while in healthcare professionals at the same period was 23%. Among the symptoms, besides fever, loss of smell and taste were more prominent in the SCD group than in healthcare professionals. There was a significant difference between the two groups in terms of development of pneumonia, hospitalization, and need for intubation (43 vs 5%, P < 0.00001; 26 vs 7%, P = 0.002; and 10 vs 1%, P = 0.002, respectively). Prophylactic low molecular weight heparin and salicylate were used more in the SCD group than in healthcare professionals group (41 vs 9% and 28 vs 1%; P < 0.0001 for both). The 3-month mortality rate was demonstrated as 5% in the SCD group, while 0 in the healthcare professionals group. One patient in the SCD group became continously dependent on respiratory support. The cause of death was acute chest syndrome in the first case, hepatic necrosis and multi-organ failure in the second case. In conclusion, these observations supported the expectation that the course of COVID-19 in SCD patients will get worse. The BASCARE program applied in SCD patients could not change the poor outcome.

ABSTRACT

INTRODUCTION: The aim of this study was to characterise the recent features of patients with infective endocarditis (IE) at one referral centre in southern Turkey, in order to be able to identify the high-risk subgroup and revise preventative measures and management strategies. METHODS: Medical records of patients 18 years and older, who had been diagnosed with IE according to the Duke criteria between January 2009 and October 2019, were retrospectively evaluated in a referral general hospital. RESULTS: The total of 139 IE cases comprised 59.7% males and 40.3% females, with a mean age of 55 ± 16 years. The most encountered symptom was fever (55.4%) and the mitral valve (54%) was the most frequently involved. The most common causative micro-organisms were coagulase-negative staphylococci (30.2%). The in-hospital mortality rate was 30.2%, with congestive heart failure, chronic renal disease and chronic dialysis found to be significantly associated with in-hospital mortality. CONCLUSIONS: The study results demonstrate the recent epidemiological features of IE in southern Turkey that are important for clinicians to manage diagnostic and therapeutic processes successfully. Older age, the predominance of staphylococci and higher surgery rates are consistent with the changing trends of IE in some parts the world.

ABSTRACT

OBJECTIVES: Urinary tract infections are the most common type of infections in kidney transplant recipients. They are also important factors for increased morbidity and mortality. The aims of this study were to evaluate the number of urinary tract infections, to identify possible donor/receiver-based risk factors, and to evaluate the impact of these infections on graft function. MATERIALS AND METHODS: Medical records of patients who had undergone kidney transplant between 2010 and 2017 were retrospectively analyzed. RESULTS: Our study included 145 patients (49 women [33.8%] and 96 men [66.2%]), with mean age of 35.2 ± 12.4 years. There were 105 episodes of urinary tract infections in 55 of 145 patients (37.9%) during the first year after transplant. Female sex (P = .001), glomerulonephritis as primary kidney disease (P = .04), pretransplant diabetes (P = .05), and presence of ureteral stent (P = .03) were significant risk factors for the development of urinary tract infections. The most frequent pathogens identified were Escherichiacoli and Klebsiella pneumoniae. Mean glomerular filtration rate t 12 months was significantly lower in patients with urinary tract infection than in patients without infection (80 ± 25 vs 68 ± 28 mL/min; P = .006). CONCLUSIONS: In kidney transplant recipients, urinary tract infections are common complications and have negative outcomes on graft function. These infections remain an important disease that requires frequent investigations and new ways of approach for prevention.

ABSTRACT

OBJECTIVE: Haematopoietic stem cell recipients need central venous catheters (CVCs) for easy administration of intravenous fluid, medications, apheresis, or dialysis procedures. However, CVCs may lead to infectious or non-infectious complications such as thrombosis. The effect of these complications on transplantation outcome is not clear. This manuscript presents the complication rates of double-lumen tunnelled CVCs and their effect on transplantation outcome. MATERIALS AND METHODS: Data from 111 consecutive patients, of whom 75 received autologous and 36 received allogeneic peripheral blood stem cell transplantations, were collected retrospectively. The data were validated by the Record Inspection Group of the related JACIE-accredited transplantation centre. RESULTS: Thrombosis developed in 2.7% of recipients (0.9 per 1000 catheter days). Catheter-related infection was identified in 14 (12.6%) patients (3.6 per 1000 catheter days). Coagulase-negative Staphylococcus was the most common causative agent. Engraftment time, rate of 100-day mortality, and development of grade II-IV graft-versus-host disease were not found to be associated with catheter-related complications. CONCLUSION: These results indicate that adverse events related with tunnelled CVCs are manageable and have no negative effects on transplant outcome.

ABSTRACT

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.

ABSTRACT

The rate of non-typhoid Salmonella infections has increased remarkably in recent years. Endovascular system infection is one of the most serious forms of extraintestinal Salmonella infection. The abdominal aorta is frequently involved, while bone and joint involvement are rarely seen. We present a rare case of successful endovascular treatment of a left iliac artery rupture and pseudoaneurysm both occurring due to the direct invasion of lumbar spondylodiscitis caused by Salmonella typhimurium.

ABSTRACT

Veterinarians and veterinary technicians are at risk for occupational brucellosis. We described the risk factors of occupational brucellosis among veterinary personnel in Turkey. A multicenter retrospective survey was performed among veterinary personnel who were actively working in the field. Of 712 veterinary personnel, 84 (11.8%) had occupational brucellosis. The median number of years since graduation was 7 (interquartile ranges [IQR], 4-11) years in the occupational brucellosis group, whereas this number was 9 (IQR, 4-16) years in the non-brucellosis group (p<0.001). In multivariable analysis, working in the private sector (odds ratio [OR], 2.8; 95% confidence interval [95% CI], 1.55-5.28, p=0.001), being male (OR, 4.5; 95% CI, 1.05-18.84, p=0.041), number of performed deliveries (OR, 1.01; 95% CI, 1.002-1.02, p=0.014), and injury during Brucella vaccine administration (OR, 5.4; 95% CI, 3.16-9.3, p<0.001) were found to be risk factors for occupational brucellosis. We suggest that all veterinary personnel should be trained on brucellosis and the importance of using personal protective equipment in order to avoid this infection.

ABSTRACT

Visceral leishmaniasis is a life threatening systemic infectious disease caused by Leishmania protozoon, which is transmitted by phlebotomine sandflies, and is widespread in Mediterranean countries including Turkey. The aim of this study was to retrospectively evaluate the visceral leishmaniasis cases followed in our clinic between January 2005 to April 2012, under the light of the current literature. A total of 14 cases (7 female, 7 male; age range: 19-64 years, mean age: 41.6 ± 12.9 years) diagnosed as visceral leishmaniasis and followed for one year after their treatment were included in the study. Data of the cases were obtained from the patient files. Ten of the cases were immunocompetent and four were immunosuppressive. While six of the cases were residents in Adana, eight were from different cities of south and southeastern Anatolia, Turkey. The median period between the development of symptoms and diagnosis was 75 (range: 2-272) days and 79% (11/14) of them were admitted to a health center and used antimicrobial agents. The leading presenting complaint was fever (100%) followed by chills and shiver (93%), weakness (71%) and weight loss (57%). Physical examination revealed fever in 8 (57%), splenomegaly in 11 (79%) and hepatosplenomegaly in 7 (50%) cases. Based on laboratory findings, pancytopenia was detected in 10 (71.4%) and hypoalbuminemia was detected in all (100%) of the cases. The diagnosis of visceral leishmaniasis was made by the detection of amastigote form of the parasite in the smears of bone marrow aspiration for 12 (86%) cases and of tissue (liver/spleen) biopsies for two cases. Bone marrow samples obtained from all of the patients were inoculated into NNN (Novy-MacNeal-Nicole) media and only 4 (29%) of them yielded the growth of Leishmania promastigots. Parenteral lipozomal amphotericin B was initiated to 10 immunocompetent patients at a dose of 3 mg/kg/day and to three immunosuppressive patients at a dose of 4 mg/kg/day. One immunosuppressive patient lost his life before initiation of treatment. With regard to disease progression, it was detected that two cases (of whom one was renal and one was bone marrow transplant patient) lost their lives (mortality rate: 14%), however all the other cases were cured completely. The present study comprised the highest number of visceral leishmaniasis adult cases reported in Turkey and enabled the review of disease characteristics. In conclusion, cases presenting with fever, hepatosplenomegaly, pancytopenia and hypoalbuminemia and living in endemic regions should be precisely evaluated in terms of visceral leishmaniasis.

ABSTRACT

Plasmodium falciparum malaria is a type of malaria with high fatality rate despite optimal antimalarial treatment. Exchange transfusion (ET) is successfully used as a means of supportive therapy in severe P. falciparum malaria cases with hyperparasitemia. Herein, we present a case with hyperparasitemia, who received erythrocyte ET therapy due to lack of clinical response to antimalarial treatment. A 24-year-old male patient was admitted to our emergency clinic with the complaints of fever that persisted for 10 days, headache, nausea-vomiting, and impaired consciousness. Medical history revealed that he had been working in Sudan, Africa and returned back 12 days ago. On physical examination; he had fever, hypotension, tachycardia, subicterus and impaired cooperation. Laboratory examination revealed pancytopenia, elevated C-reactive protein, hyperbilirubinemia, hyponatremia, elevated creatinine level and hematuria. On thick blood smear and thin blood smear examinations, multiple (> 5%) trophozoites and gametocytes indicating P.falciparum species were observed. The case was diagnosed as P.falciparum malaria and parenteral fluid support, dopamine infusion, meropenem (IV), doxycycline (PO) and quinine sulphate (PO) were initiated in the intensive care unit. On reevaluation of the patient on the third day of hospitalization, it was observed that arterial hypotension and fever were persistent, anemia and trombocytopenia deteriorated and on thick blood smear parasitemiea was not decreased. It was decided to apply automated erythrocyte ET. After ET, patient's medical status was quickly improved and patient was discharged on the 7th day of hospitalization. In conclusion, it was noted that in addition to antimalarial treatment, erythrocyte ET may provide dramatic improvement in severe cases of P.falciparum malaria with hyperparasitemia.

ABSTRACT

Extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae strains are frequent causative agents both in community-acquired infections and in nosocomial infections. The newly developed ChromID ESBL agar (bioMerieux, Marcy I'Etoile, France) is a chromogenic medium that helps rapid identification of ESBL-positive Enterobacteriaceae species from the clinical samples. The aim of this study was to evaluate the performance of ChromID ESBL agar in the rapid identification of ESBL-positive pathogens from the urine samples of the patients with urinary tract infections. A total of 672 urine samples (437 outpatients, 235 inpatients) were included in the study. All of the samples were inoculated simultaneously to 5% sheep blood agar, McConkey agar and ChromID ESBL agar media, and evaluated after incubation at 37°C for 18-24 hours. Gram-negative pathogens were tested for ESBL both by the standard combined double-disk diffusion (CDD) method using ceftazidime and cefotaxime disks and by doubledisk synergy (DDS) test. Among 672 urine cultures, 199 yielded microbial growth in routine media (sheep blood agar and/or McConkey agar), whereas 57 yielded bacterial growth in ChromID ESBL agar. When CDD method was accepted as the reference method according to Clinical and Laboratory Standards Institute (CLSI) recommendations, the sensitivity, specificity, positive and negative predictive values for ChromID ESBL agar for the detection of ESBL-positive bacteria in urinary tract infections were estimated as 97%, 92.9%, 89.1%, and 98.1%, respectively. Additionally, we also discovered that Chrom ID ESBL agar could detect vancomycin-resistant enterococci (VRE) as well as ESBL-positive bacteria, in our study. In order to investigate this observation we inoculated a total of 203 stock strains of Enterococcus spp. (118 vancomycin-sensitive, 85 vancomycin-resistant) to this medium. None of the vancomycinsensitive Enterococcus spp. did grow in ChromID ESBL medium, while 83 of the 85 resistant isolates (97.6%) did grow in the medium. As a result, it was concluded that ChromID ESBL agar medium was advantageous since it led to the growth of VRE and ESBL-positive Enterobacteriaceae isolates in different colors and helped in early identification of these two problematic bacteria. We thought that especially early detection of VRE will accelerate the establishment of necessary measures to prevent the nosocomial spread of this microorganism.

ABSTRACT

The aim of this retrospective study was to describe and to categorize different clinical pictures of patients with neurobrucellosis in our clinic, and present demographical and laboratory data about the patients. Hospital records of 430 patients with brucellosis between 2003 and 2009, were retrospectively reviewed. Out of 430 patients, 19 (4.4%) had neurobrucellosis. These patients were classified into four groups: Meningitis group (n= 14, 13 cases of subacute/chronic meningitis, one case of acute meningitis), encephalomyelitis group (n= 3, one case of meningoencephalomyelitis, one case of cerebellar abscess and one case of transverse myelitis), polyradicular group (n= 1, Miller-Fisher Syndrome), and others (n= 1, one case of intradural abscess). Ten patients (52.6%) were female, and the mean age of the patients was 48.8 years. About 47.4% of the patients had fever, 26% of the patients had neck stiffness and 5% of the patients were in an unconscious state. Out of 19 patients, 18 underwent lumbar puncture and they had positive brucella antibody test in cerebrospinal fluid (CSF) by standard tube agglutination method. Brucella spp. Were grown in four patient's blood culture and one patient's CSF culture. There were cranial nerve involvement in five cases, the most frequent being the sixth cranial nerve. Out of 19 patients, three recovered with sequela (paraparesis, hearing loss, dementia and sphincter disfunction) and 16 patients recovered completely. Although neurobrucellosis is most frequently presented as subacute/chronic meningitis, it may be associated with different clinical pictures. The classical triad of meningitis (fever, neck stiffness, unconsciousness) is rarely seen in brucellosis-related meningitis. Brucellosis should be kept in mind in patients with unexplained neurological findings particularly in areas where brucellosis is endemic. In addition, a current classification of neurobrucellosis, related to involved location of nervous system, clinical picture and pathogenesis, is needed.

ABSTRACT

PURPOSE: To present chest radiography and thoracic computed tomography (CT) findings for patients with pandemic influenza A (H1N1) from November-December 2009 and to explore any differences compared to previously reported imaging findings. MATERIALS AND METHODS: Fifty-two hospitalized patients with pandemic influenza (H1N1) were included in the study. All of the patients underwent chest radiography, and 28 patients were also evaluated by thoracic CT. Group 1 comprised 24 (46%) patients with no identified risk factors for H1N1 influenza infection. Group 2 comprised the remaining 28 (54%) patients with identified risk factors. The distribution of lung involvement, consolidation, ground-glass opacity (GGO), lymph nodes, and pleural effusion were evaluated. RESULTS: Abnormal findings were observed in 85% of the patients. Bilateral lung involvement was present in 80% of the patients. The most common finding was a mixture of GGO and air-space consolidation. Lower zone predominance occurred in 89% of group 1 and 85% of group 2 patients. The involvement was observed most frequently in the peripheral and central perihilar areas of the lung in 80% of the patients. The extent of disease was greater in group 2 patients with the involvement of three or more lung zones in 62% of the patients. CONCLUSION: The most common imaging finding for lung involvement was a mixture of air-space consolidation and GGO with a patchy pattern and lower/middle zone predominance. Pulmonary involvement of the disease was more extensive than that described in previous reports.

ABSTRACT

Visceral leishmaniasis is a rare opportunistic infection in renal transplantation patients and its presentation may be associated with or masked by many other factors in immunosuppressed patients. So, if it is not searched for in particular, diagnosis may be easily overlooked or delayed in renal transplant patients. A 32-year-old renal transplant recipient devoleped splenomegaly, pyrexia and pancytopenia. Six months after the first bone marrow examination, the delayed diagnosis was made possible by a second bone marrow aspiration. Liposomal amphotericin B was effective in his treatment although he had a recurrence. Early diagnosis of visceral leishmaniasis is crucial for the renal transplant recipient's therapy; and even in treated patients, the mortality rate may be high. In our case, although the time up to diagnosis was as long as six months after the onset of symptoms, response to treatment was satisfactory with higher doses of liposomal amphotericin B in the second cycle. Also, in the short term, the rate of recurrence was comparable to other reported patients who were diagnosed and treated in a month.

ABSTRACT

Peritonitis due to brucellosis is extremely rare and the reported cases are mostly chronic hepatic failure patients with ascites or chronic renal failure patients on continuous ambulatory peritoneal dialysis. We report a 20-year-old male patient, with no underlying disease, who was diagnosed as peritonitis due to brucellosis mimicking tuberculosis, with ascites with pleocytosis, lymphocytic predominance and high levels of adenosine deaminase.
