RESUMO

INTRODUCTION: In this study, our aim was to prospectively compare the different methods of patient disinfections with scrubbing + iodine + alcohol, and the povidone iodine disinfection method, which can be described as classical, in terms of the pathogens isolated on skin and during early postoperative complications. METHODOLOGY: Eighty patients undergoing a coronary artery bypass operation were included in the study. The patients were divided into two groups: group 1 (n = 48) patients who underwent scrub, iodine, followed by skin disinfection with alcohol, and group 2 (n = 32) who were treated with povidone iodine three times. The samples were immediately sent to the microbiology laboratory. Specimens from the wounds were incubated under aerobic and anaerobic conditions, and isolates were identified using standard microbiological techniques. RESULTS: In samples taken after disinfection in group 1, significantly less reproduction was observed compared to group 2 (p = 0.001). There was no difference in postoperative complications between the two groups except for pleural effusion (p = 0.040). S. epidermidis was the most frequently isolated pathogen in both groups. CONCLUSION: We did not find a study which compares scrub + alcohol + iodine and povidone iodine in our literature review. We think that our study is original in this respect. We can conclude that skin disinfection with scrub + alcohol + iodine was superior to using only povidone iodine in terms of the pathogens isolated afterwards from the wound.

RESUMO

Ventilator-associated pneumonia (VAP) due to Acinetobacter spp. is one of the most common infections in the intensive care unit. Hence, we performed this prospective-observational multicenter study, and described the course and outcome of the disease. This study was performed in 24 centers between January 06, 2014, and December 02, 2016. The patients were evaluated at time of pneumonia diagnosis, when culture results were available, and at 72 h, at the 7th day, and finally at the 28th day of follow-up. Patients with coexistent infections were excluded and only those with a first VAP episode were enrolled. Logistic regression analysis was performed. A total of 177 patients were included; empiric antimicrobial therapy was appropriate (when the patient received at least one antibiotic that the infecting strain was ultimately shown to be susceptible) in only 69 (39%) patients. During the 28-day period, antibiotics were modified for side effects in 27 (15.2%) patients and renal dose adjustment was made in 38 (21.5%). Ultimately, 89 (50.3%) patients died. Predictors of mortality were creatinine level (OR, 1.84 (95% CI 1.279-2.657); p = 0.001), fever (OR, 0.663 (95% CI 0.454-0.967); p = 0.033), malignancy (OR, 7.095 (95% CI 2.142-23.500); p = 0.001), congestive heart failure (OR, 2.341 (95% CI 1.046-5.239); p = 0.038), appropriate empiric antimicrobial treatment (OR, 0.445 (95% CI 0.216-0.914); p = 0.027), and surgery in the last month (OR, 0.137 (95% CI 0.037-0.499); p = 0.003). Appropriate empiric antimicrobial treatment in VAP due to Acinetobacter spp. was associated with survival while renal injury and comorbid conditions increased mortality. Hence, early diagnosis and appropriate antibiotic therapy remain crucial to improve outcomes.

RESUMO

Although there is no other underlying disease, women can sometimes experience rare and serious diseases such as ovarian vein thrombosis (OVT) and renal vein thrombosis (RVT) after giving birth. The widespread development of thrombosis is treated for the first time in this study. Stasis, coagulation factor abnormalities, and intimal damage to the venous thrombosis risk can increase during pregnancy. It was mentioned that it diagnoses an abnormality in the hypercoagulability half of women with OVT. Despite the hypercoagulant abnormality observed in pregnant women, it was very unusual that the renal vein thrombosis led to this complication. It can lead to severe complication of OVT which can even cause death. It was the first time that the renal vein and ovarian vein thrombosis were observed in the postpartum period, and there was no coagulation abnormality. It is known that the thrombus in the postpartum period can be observed with the fever of unknown origin. The problematic, but rarely observed, postpartum disease such as ovarian venous thrombosis (OVT) is generally observed in the right ovarian vein. In this disease, avoiding the resulting laparotomy heparin and intravenous antibiotics is best solution for the patient. If it is to be noted a fever for unknown reasons, that it be thrombosis.

RESUMO

Plasmodium vivax malaria is usually seen in our country. Plasmodium falciparum malaria is also detected in the patients who have travelled abroad. A 33 year old male patient applied to our hospital for control. One month ago our patient had travelled to Angola where P. falciparum malaria is endemic. He had been diagnosed with malaria in Iran and successfully treated with quinine, doxycycline, and clindamycin. This time in our patient without any complaints, splenomegaly and splenic infarction were found. In our patient follow-ups it was observed that splenic infarction shrank. Therefore, in this article we present this rare complication.

RESUMO

BACKGROUND: Brucellosis is an inflammatory disease which may infect any organs or systems in the body. Mean Platelet Volume (MPV) is one of the most frequently used surrogate markers of platelet function. It reveals the presence of disease activity in many inflammatory diseases. Red blood cell distribution width (RDW) is a parameter that measures variation in red blood cell size or red blood cell volume. Its predictive value approves inflammatory and infectious diseases. OBJECTIVES: The current study aimed to determine the assessment levels of red blood cell distribution in cases with acute brucellosis. PATIENTS AND METHODS: The current study investigated whether MPV and RDW played any roles in acute brucellosis diagnosis. The study was conducted from 2008 to 2014 through prospective examination of the inflammatory markers found in adult patients with acute brucellosis. RESULTS: The follow-up within the year after treatment was examined. The values of age, gender, leukocyte count, C-reactive protein, RDW and MPV were recorded. The study included 351 subjects, 250 of them in the acute brucellosis group and 101 in the control group. The mean MPV levels were 7.64 ± 1.30 fL, and 7.67 ± 1.29 fL in the acute brucellosis and control groups, respectively (P > 0.05). The mean CRP levels were 32.57 ± 53.20 mg/dL, and 4.81 ± 4.89 mg/dL in the acute brucellosis and control groups, respectively (P < 0.05). There was no statistically significant difference between the two groups regarding the RDW level and the mean leukocyte count (P > 0.05). CONCLUSIONS: While the CRP value was in patients with acute brucellosis in the current study, the MPV, RDW and leukocyte counts were within the normal range. CRP value remains the most valuable inflammatory marker in cases of acute brucellosis.

RESUMO

INTRODUCTION: In this study, we examined the effects of Brucella infection on endothelial dysfunction. Flow-mediated dilatation (FMD) measurement is indicator of the endothelial function, and abnormal values indicating endothelial dysfunction are accepted as the first stage of atherosclerosis. METHODOLOGY: Twenty-four patients who had been treated for acute brucellosis two years before, and who had had no relapses in the follow-up, were prospectively included in the study, along with 30 healthy individuals in the control group. RESULTS: While the highly sensitive C-reactive protein (hs-CRP) value was 2.42 ± 1.45 in the patient group, it was 1.72 ± 0.61 in the control group (p = 0.025). While the FMD value was 3.50 ± 1.58 in the patient group, it was 5.88 ± 1.88 in the control group (p < 0.001). While the percentage increase in FMD was 9.88 ± 4.92 in the patient group, it was 17.49 ± 6.3 in the control group (p < 0.001). It was observed that FMD value, the percentage increase in FMD, and basal radius were correlated with hs-CRP (r = -0.644, p < 0.001; r = - 0.558, p = 0.002; r = 0.444, p = 0.018, respectively). The carotid artery intima media thickness (IMT) value was found to be 0.61 ± 0.17 in the patient group and 0.49 ± 0.12 in the control group (p = 0.004). CONCLUSIONS: The abnormal FMD and IMT values observed in brucellosis patients might be an indicator of more frequent arterial dysfunction, increased cardiovascular risk, and atherosclerosis.

RESUMO

Flame burns are a serious condition and usually have high morbidity and mortality because they affect large areas of the body surface as well as the lungs. In these patients, it is especially difficult to find healthy skin for grafting if they have more than 70% third-degree burns. Repeated autografting or synthetic wound care materials are the only treatment options to cover burned areas. Partial-thickness skin grafting from the patient's identical twin sibling may be an alternative treatment option, if possible. Here, we report a patient with severe flame injury treated with skin from his identical twin. The patient had third-degree burns covering 70% of his body surface. Initial treatment consisted of fluid and electrolyte replacement, daily wound care, and surgical debridements, as well as nutritional support. After initial treatment, we performed a successful skin grafting from his identical twin. Skin grafting between identical twins might be an alternate method for severely burned patients.

RESUMO

Coccidioidomycosis is a fungal infection caused by the Coccidioides species, endemic to the southwestern United States. In healthy people, manifestations range mainly from asymptomatic to mild influenza-like signs, whereas in immunosuppressed patients (eg, transplant recipients) this infection is often a severe disseminated disease. We report a case of primary pulmonary coccidioidomycosis in a 61-year-old man with a renal transplant 7 months earlier. The patient had nonspecific symptoms of pulmonary infection, including weakness, anorexia, and weight loss. Both spherules and endospores of Coccidioides immitis were seen histologically after a transbronchial biopsy of a cavitary lesion. The patient was treated with amphotericin B. At the time of this writing (8 months), he remains disease free.

RESUMO

We report the case of a 75-year-old male patient who was treated in our clinic for septicemia and subacute infective endocarditis caused by toxigenic Candida albicans. Transthoracic echocardiography revealed the presence of a thrombus in the left atrial cavity, and the diagnosis was confirmed by computerized tomography. The patient was operated on urgently. Histological examination of the embolic material removed from the left atrium showed the presence of yeast and hyphal forms of Candida albicans through periodic acid-Shiff stain. The patient was readmitted to the hospital on postoperative day 15, because of reembolism, and died later on. Here we present our approach to the diagnosis and treatment of this rare condition.

RESUMO

BACKGROUND: In the past, Staphylococcus aureus infections have displayed various patterns of epidemiologic curves in hospitals, particularly in intensive care units (ICUs). This study aimed to characterize the current trend in a nationwide survey of ICUs in Turkey. METHODS: A total of 88 ICUs from 36 Turkish tertiary hospitals were included in this retrospective study, which was performed during the first 3 months of both 2008 (period [P] 1) and 2011 (P2). A P value ≤.01 was considered significant. RESULTS: Although overall rates of hospital-acquired infection (HAI) and device-associated infection densities were similar in P1 and P2, the densities of HAIs due to S aureus and methicillin-resistant S aureus (MRSA) were significantly lower in P2 (P < .0001). However, the proportion of HAIs due to Acinetobacter was significantly higher in P2 (P < .0001). CONCLUSIONS: The incidence of S aureus infections is declining rapidly in Turkish ICUs, with potential impacts on empirical treatment strategies in these ICUs.

RESUMO

BACKGROUND: In patients with symptomatic cholelithiasis, laparoscopic cholecystectomy (LC) is the standard method of treatment. Laparoscopic cholecystectomy has a low rate of postoperative infections probably owing to smaller wounds and minimal tissue damage compared with the open procedure. OBJECTIVES: This study assessed the effect of cefazolin prophylaxis on postoperative infection in patients undergoing elective laparoscopic cholecystectomy. Additionally, we determined the risk factors of cases with postoperative infection. PATIENTS AND METHODS: A total of 753 patients were enrolled in the study. Among these, 206 were excluded from the study. As a result, 547 patients with symptomatic cholelithiasis who underwent elective laparoscopic cholecystectomy were selected for this prospective study. Patients were randomized consecutively and divided into 2 groups: patients in the cefazolin (CEF) group (n = 278) received 1 g of cefazolin and those in the control group (n = 269) received 10 mL of isotonic sodium chloride solution. Patient characteristics and overall surgical outcomes were compared between the groups. All patients were followed for development of postoperative infections. RESULTS: Postoperative infections occurred in 4 patients in the CEF group and in 2 patients in the control group; no significant difference existed in this regard(P = .44). Risk of infection increased in patients with previous cholecystitis and/or endoscopic retrograde cholangiopancreatography (P < 0.001), patients with ruptured gallbladders, and patients for whom a suction drain was used (respectively, P < 0.001 and P < 0.001). CONCLUSIONS: No correlation existed between cefazolin prophylaxis and postoperative infections in elective laparoscopic cholecystectomy patients. There may be an increased risk of infection in patients with previous cholecystitis or endoscopic retrograde cholangiopancreatography. In addition, there was an increased risk of postoperative infection in patients with gallbladder rupture and suction drain use.

RESUMO

OBJECTIVE: The musculoskeletal system is one of the most commonly affected systems in brucellosis. The objective of this study was to determine the frequency, types, and clinical features of osteoarticular involvement among cases with brucellosis in the Central Anatolia region of Turkey and to establish the differences between patients with and without osteoarticular involvement. METHODS: Included in this study were 202 patients with Brucellosis presented between June 2003 and June 2009. The diagnosis of osteoarticular system complications was established by physical examination and radiological findings obtained by diagnostic imaging tools. Magnetic resonance images of thoracic, lumbar or sacral vertebrae were acquired from patients with back pain, low back pain and sacro-iliac joint pain. RESULTS: Osteoarticular involvement was noted in 94 patients (46.5%). The most common sources of infection are employment in farming and/or consumption of un-pasteurized milk or dairy products, especially fresh cheese in 53 (75.7%) cases. The mean age is 46.7±18 years. Sacroiliitis is the most frequent osteoarticular involvement (60.6%), 82.4% of which is bilateral. Sacroiliitis was followed by spondylodiscitis in 36 (38.3%), peripheral arthritis in 15 (16%), bursitis in 1(1.1%) case. Patients with osteoarticular involvement received medical treatment for at least three months. CONCLUSION: The ratio and anatomical region of osteoarticular involvement in brucellosis show variability among countries. In this study, it is demonstrated that sacroiliitis is the most common form of osteoarticular involvement in the Central Anatolia region of Turkey. In endemic countries such as Turkey, this disease should be included in the differential diagnosis for patients with symptoms of sacroiliitis, spondylodiscitis or those with articular pain.

RESUMO

OBJECTIVES: Migraine is a risk factor for ischemic stroke. Sterile vascular inflammation may develop during migraine attacks. This study aims to investigate procalcitonin (PCT) levels amongst migraine patients as they are important markers for infection and sepsis, but can also be found at elevated levels in various cases of inflammation. METHODS: Eighty adult migraine patients participated in our study. Patients were initially separated into two main groups; Group-1 consisted of 34 patients who had migraines during the attack period. Group-2 consisted of 46 patients during the period in-between attacks. Afterwards, patients were further divided into four subgroups based on their aura status; Group-1a Migraine without aura, 27 patients during attack period, Group-1b Migraine with aura, 7 patients during attack period, Group-2a Migraine without aura, 40 patients during the period in-between attacks, Group-2b Migraine with aura, 6 patients during the period in-between attacks. RESULTS: Average PCT levels in patients during attack periods were found to be higher than the average PCT levels of patients during the period in-between attacks. These elevated levels were determined to be statistically significant(p<0.01). Serum PCT levels of the patients with migraine without aura during the attack period were significantly higher than those of patients during the period in-between attacks(p<0.01). CONCLUSIONS: Based on significantly high levels of PCT, our results support the idea that sterile inflammation plays a role in migraine pathogenesis. Further studies are necessary to understand whether PCT is a marker for ischemic stroke risk in patients who go through frequent migraine attacks.

RESUMO

This prospective case-control study was conducted from October 2003 to June 2007 to evaluate risk factors for multidrug resistance among extended-spectrum-b-lactamase-producing Escherichia coli and Klebsiella spp. (ESBL-EK) isolates in blood cultures. All adult patients (>18 years old) whose blood cultures grew ESBL-EK during the study period were included. An ESBL-EK isolate was defined as MDR if it was resistant to at least one member of following two classes of antibiotics: aminoglycosides (amikacin, gentamicin, or netilmycin) and fluoroquinolones (ofloxacin, or ciprofloxacin). Case patients were those with a MDR ESBL-EK isolate, and control patients were those with a non-MDR ESBL-EK isolate. A total of 94 bloodstream infections, including 37 (39,4 percent) bloodstream infections with ESBL-producing E. coli and 57 (60,6 percent) with ESBL-producing K. pneumoniae,in 86 patients were enrolled. Thirty episodes (31.9 percent) were due to MDR ESBL-EK. The only independent risk factor for MDR ESBL-EK was duration of hospitalization before bacteraemia (OR 3.88; 95 percent CI 1.55-9.71; p=0.004). The rate of multidrug resistance among ESBL-EK bloodstream isolates was high, and duration of hospitalization before bacteraemia was the only indeepended risk factor for the MDR ESBL-EK bloodstream infections.

RESUMO

Oxidative stress can be defined as an increase in oxidants and/or a decrease in antioxidant capacity. We aimed to determine total antioxidant capacity (TAC), total peroxide, malondialdehyde and catalase levels in plasma samples, and calculation of oxidative stress index (OSI) in patients with brucellosis to evaluate their oxidative status using a novel automated method. Sixty-nine patients with brucellosis and 69 healthy control subjects were included in the present study. Plasma levels of total peroxide and malondialdehyde were significantly increased in patients as compared with healthy controls (p<0.001 and p<0.001, respectively). In contrast, TAC level was significantly lower in patients as compared with controls (p<0.001). There was no statistically significant difference between the catalase results of the two groups (p>0.05). OSI level was significantly increased in patients as compared with healthy controls (p<0.001). In conclusion, oxidants were increased and antioxidants were decreased in patients with brucellosis. Oxidative stress was increased in patients with brucellosis.

RESUMO

Brucellosis is a systemic infection involving many organs and tissues. The musculoskeletal system is one of the most commonly affected. The disease can present with sacroiliitis, peripheral arthritis, spondylitis, paraspinal abscess, bursitis, and osteomyelitis. A 25-year-old male patient was admitted with fever of 20-day duration, right-sided hip pain, and night sweating. A Brucella standard tube agglutination test was positive at a titer of 1/160. Magnetic resonance imaging (MRI) of the hip joint showed right sacroiliitis and a hyperintense, nodular, lobulated mass within the right iliacus muscle, consistent with abscess. The patient was started on intramuscular streptomycin at a dose of 1 g/day, oral rifampin 600 mg/day, and doxycycline 200 mg/day. On day 20 of treatment, the patient was admitted with swelling and pain over the left elbow for the past week. MRI of the left elbow was performed, which showed fluid edema suggestive of olecranon bursitis. Taking the patient's complaints into consideration, rifampin and doxycycline treatment were maintained for a year. Pain at the hip joint and elbow resolved and MRI findings disappeared. Abscess of the iliacus muscle, which has not been reported before, and the olecranon bursitis that developed during treatment make this case worth presenting.

OSI level was significantly increased in patients as compared with healthy controls (p<0.001). In conclusion, oxidants were increased and antioxidants were decreased in patients with brucellosis. Oxidative stress was increased in patients with brucellosis.

RESUMO

This prospective case-control study was conducted from October 2003 to June 2007 to evaluate risk factors for multidrug resistance among extended-spectrum-b-lactamase-producing Escherichia coli and Klebsiella spp. (ESBL-EK) isolates in blood cultures. All adult patients (>18 years old) whose blood cultures grew ESBL-EK during the study period were included. An ESBL-EK isolate was defined as MDR if it was resistant to at least one member of following two classes of antibiotics: aminoglycosides (amikacin, gentamicin, or netilmycin) and fluoroquinolones (ofloxacin, or ciprofloxacin). Case patients were those with a MDR ESBL-EK isolate, and control patients were those with a non-MDR ESBL-EK isolate. A total of 94 bloodstream infections, including 37 (39,4%) bloodstream infections with ESBL-producing E. coli and 57 (60,6%) with ESBL-producing K. pneumoniae,in 86 patients were enrolled. Thirty episodes (31.9%) were due to MDR ESBL-EK. The only independent risk factor for MDR ESBL-EK was duration of hospitalization before bacteraemia (OR 3.88; 95% CI 1.55-9.71; p=0.004). The rate of multidrug resistance among ESBL-EK bloodstream isolates was high, and duration of hospitalization before bacteraemia was the only indeepended risk factor for the MDR ESBL-EK bloodstream infections.

RESUMO

AIM: To evaluate the preoperative and intraoperative factors that might affect development of fever following percutaneous nephrolithotomy (PCNL) and to investigate the clinical significance of intraoperative microbiologic evaluation in managing postoperative infectious complications. PATIENTS AND METHODS: Sixty-one consecutive patients who had undergone PCNL between October 2006 and June 2007 were prospectively recruited into the study. Preoperative urine cultures and intraoperative stone and pelvic urine cultures were obtained from all patients. Postoperatively, patients were closely monitored for fever and other signs of systemic inflammatory response syndrome. RESULTS: Of 61 patients, 10 (16.8%) had at least one body temperature recorded at 38 degrees C (group 1), the remaining patients were afebrile (group 2). Fever was associated with a systemic inflammatory response syndrome in one patient (1.6%); in that patient, the antibiotic regimen was altered. There were statistically significantly more positive stone culture results for patients in group 1 than there were for patients in group 2 (5/10 versus 9/51, P < 0.05). There were statistically significantly more positive pelvic urine culture results for patients in group 1 than there were for patients in group 2 (3/10 versus 2/51, P < 0.05). Patients in group 1 also had longer operative times and larger stone burdens than did patients in group 2. CONCLUSIONS: Intraoperative microbiologic evaluation may be important in postoperative antibiotic selection and should be routinely used.
