RESUMO

Data are relatively scarce on gastro-intestinal tuberculosis (GITB). Most studies are old and from single centers, or did not include immunosuppressed patients. Thus, we aimed to determine the clinical, radiological, and laboratory profiles of GITB. We included adults with proven GITB treated between 2000 and 2018. Patients were enrolled from 21 referral centers in 8 countries (Belgium, Egypt, France, Italy, Kazakhstan, Saudi Arabia, UK, and Turkey). One hundred four patients were included. Terminal ileum (n = 46, 44.2%), small intestines except terminal ileum (n = 36, 34.6%), colon (n = 29, 27.8%), stomach (n = 6, 5.7%), and perianal (one patient) were the sites of GITB. One-third of all patients were immunosuppressed. Sixteen patients had diabetes, 8 had chronic renal failure, 5 were HIV positive, 4 had liver cirrhosis, and 3 had malignancies. Intestinal biopsy samples were cultured in 75 cases (78.1%) and TB was isolated in 65 patients (86.6%). PCR were performed to 37 (35.6%) biopsy samples and of these, 35 (94.6%) were positive. Ascites samples were cultured in 19 patients and M. tuberculosis was isolated in 11 (57.9%). Upper gastrointestinal endoscopy was performed to 40 patients (38.5%) and colonoscopy in 74 (71.1%). Surgical interventions were frequently the source of diagnostic samples (25 laparoscopy/20 laparotomy, n = 45, 43.3%). Patients were treated with standard and second-line anti-TB medications. Ultimately, 4 (3.8%) patients died and 2 (1.9%) cases relapsed. There was a high incidence of underlying immunosuppression in GITB patients. A high degree of clinical suspicion is necessary to initiate appropriate and timely diagnostic procedures; many patients are first diagnosed at surgery.

RESUMO

Neurosyphilis (NS) has different clinical manifestations and can appear during any stage of syphilis. We aimed to identify the factors affecting poor outcome in NS patients. Patients with positive cerebrospinal fluid Venereal Disease Research Laboratory test, and positive serological serum treponemal or nontreponemal tests were classified as definite NS. The data of 141 patients with definite NS were submitted from 22 referral centers. Asymptomatic NS, syphilitic meningitis, meningovascular syphilis, tabes dorsalis, general paresis, and taboparesis were detected in 22 (15.6%), 67 (47.5%), 13 (9.2%), 10 (7%), 13 (9.2%), and 16 patients (11.3%), respectively. The number of HIV-positive patients was 43 (30.4%). The most common symptoms were headache (n = 55, 39%), fatigue (n = 52, 36.8%), and altered consciousness (50, 35.4%). Tabetic symptoms were detected in 28 (19.8%), paretic symptoms in 32 (22.6%), and vascular symptoms in 39 patients (27.6%). Eye involvement was detected in 19 of 80 patients (23.7%) who underwent eye examination and ear involvement was detected in eight of 25 patients (32%) who underwent ear examination. Crystallized penicillin was used in 109 (77.3%), procaine penicillin in seven (4.9%), ceftriaxone in 31 (21.9%), and doxycycline in five patients (3.5%). According to multivariate regression analysis, while headache was a protective factor in NS patients, double vision was significantly associated to poor outcome. We concluded that double vision indicated unfavorable outcome among NS patients. A high clinical suspicion is needed for the diagnosis NS. As determined in our study, the presence of headache in syphilitic patients can help in early diagnosis of central nervous system disease.

RESUMO

Brucellosis in pregnant women is reported to be associated with obstetric complications (OCs), and adequate data for human brucellosis during pregnancy are largely lacking. We performed this multicenter retrospective cross-sectional study to evaluate the epidemiology, clinical course, treatment responses, and outcomes of brucellosis among pregnant women. The study period comprised a 14-year period from January 2002 to December 2015. All consecutive pregnant women diagnosed with brucellosis in 23 participating hospitals were included. Epidemiological, clinical, laboratory, therapeutic, and outcome data along with the assessment data of the neonate were collected using a standardized questionnaire. Data of 242 patients were analyzed. The OC rate was 14.0% (34/242) in the cohort. Of the 242 women, 219 (90.5%) delivered at term, 3 (1.2%) had preterm delivery, 15 (6.2%) aborted, and 5 (2.1%) had intrauterine fetal demise. Seventeen (7.0%) of the newborns were considered as low birth weight. Spontaneous abortion (6.1%) was the commonest complication. There were no maternal or neonatal deaths and pertinent sequelae or complications were not detected in the newborns. Splenomegaly (p = 0.019), nausea and/or vomiting (p < 0.001), vaginal bleeding (p < 0.001), anemia (blood hemoglobin < 11 g/dL; p < 0.001), high level of serum aspartate aminotransferase (> 41 IU/L; p = 0.025), oligohydramnios on ultrasonography (p = 0.0002), history of taking medication other than Brucella treatment during pregnancy (p = 0.027), and Brucella bacteremia (p = 0.029) were the significant factors associated with OCs. We recommend that pregnant women with OC or with fever should be investigated for brucellosis if they live in or have traveled to an endemic area.

RESUMO

Infective endocarditis is a growing problem with many shifts due to ever-increasing comorbid illnesses, invasive procedures, and increase in the elderly. We performed this multinational study to depict definite infective endocarditis. Adult patients with definite endocarditis hospitalized between January 1, 2015, and October 1, 2018, were included from 41 hospitals in 13 countries. We included microbiological features, types and severity of the disease, complications, but excluded therapeutic parameters. A total of 867 patients were included. A total of 631 (72.8%) patients had native valve endocarditis (NVE), 214 (24.7%) patients had prosthetic valve endocarditis (PVE), 21 (2.4%) patients had pacemaker lead endocarditis, and 1 patient had catheter port endocarditis. Eighteen percent of NVE patients were hospital-acquired. PVE patients were classified as early-onset in 24.9%. A total of 385 (44.4%) patients had major embolic events, most frequently to the brain (n = 227, 26.3%). Blood cultures yielded pathogens in 766 (88.4%). In 101 (11.6%) patients, blood cultures were negative. Molecular testing of vegetations disclosed pathogens in 65 cases. Overall, 795 (91.7%) endocarditis patients had any identified pathogen. Leading pathogens (Staphylococcus aureus (n = 267, 33.6%), Streptococcus viridans (n = 149, 18.7%), enterococci (n = 128, 16.1%), coagulase-negative staphylococci (n = 92, 11.6%)) displayed substantial resistance profiles. A total of 132 (15.2%) patients had cardiac abscesses; 693 (79.9%) patients had left-sided endocarditis. Aortic (n = 394, 45.4%) and mitral valves (n = 369, 42.5%) were most frequently involved. Mortality was more common in PVE than NVE (NVE (n = 101, 16%), PVE (n = 49, 22.9%), p = 0.042).

RESUMO

Infection control is a top priority for hospitals, especially in intensive care units (ICU). In intensive care units, prevalence of infection is estimated to be 30% worldwide, which is a major cause of morbidity and mortality. Many factors are known to increase the risk of infection in ICU patients. Since each of these may lead to different infections, it is important to recognize and identify predisposing factors for early diagnosis and treatment. The regional health care-associated infections (HCAI) prevalence and distribution of risk factors are important strategies in infection control. In this regard, the aim of this point prevalence study was to obtain data related to infections, the prevalence of HCAI among these infections, the epidemiology, agents and antibiotics used among adult ICU patients in the university hospitals, training and research hospitals and public hospitals located in eight of the cities of our region. In the light of these data, we aimed to review and emphasize the guidelines on HCAI prevention. The study included adult ICU patients followed up in nine hospitals in the Eastern and South-eastern Anatolia Regions of eight different cities (Sivas, Erzurum, Mardin, Batman, Diyarbakir Elazig, Van, Adiyaman) in Turkey. Of the hospitals six were university hospitals, one was training and research hospital, and two were public hospitals. The number of beds ranged from 358 to 1418. A specific day was determined on which the researchers concurrently carried out a prospective surveillance in all adult intensive care unit patients. The researchers collected data and recorded the demographic characteristics (age, gender), underlying diseases, length of hospital stay, presence of invasive intervention (urinary catheter, central venous catheter, external ventricular drainage, mechanical ventilator, presence of risk factors such as burn, trauma and surgery, number of infection cases, type of infection (hospital-acquired, community-acquired), type of microorganisms and whether polymicrobial or monomicrobial, which antibiotics were administered, and duration of antibiotic treatment. Our study assessed data of 429 inpatients in the adult ICU of nine hospitals in eight different cities. There were a total of 881 intensive care beds in these hospitals, and 740 (84%) beds were occupied. Of the study group 49.7% was male with a mean age (min-max) of 64.08 ± 18.78 (2-97) years. The point prevalence of HCAI was 21.7% (n= 93). Of the patients who were followed-up 182 (42.4%) presented infections. Of these infections, 21.4% were diagnosed as community-acquired pneumonia, 18.6% were ventilator-associated pneumonia (VAP), 16.3% were communityacquired urinary tract infection (UTI), and 16.3% were bloodstream infection. In addition, the most commonly administered antibiotics in the study group were piperacillin/tazobactam, carbapenem, quinolone and ceftriaxone, respectively. The most common types of HCAI were community-acquired pneumonia (10.7%), ventilator-associated pneumonia (8.9%) and bloodstream infections (8.2%). The mean length of hospital stay was 32.05 ± 66.85 (1-459) days and the mean duration of antibiotic therapy in patients with HCAIs was 7.76 ± 7.11 (1-41) days. The most widely accepted method to handle infection is to carry out active, prospective and patient-based surveillance studies on a regular basis, and to take control measures and arrange appropriate treatment in the light of the data obtained. We attribute the high prevalence of HCAI in our region to lack of personnel, lack of materials, inappropriate use of antibiotics, insufficiency of physical conditions, and little support for infection control committees. In conclusion, we emphasize that it is of importance to work closely with the hospital administration to take measures and that necessary assistance is provided.

RESUMO

OBJECTIVE: Neuroimaging abnormalities in central nervous system (CNS) brucellosis are not well documented. The purpose of this study was to evaluate the prevalence of imaging abnormalities in neurobrucellosis and to identify factors associated with leptomeningeal and basal enhancement, which frequently results in unfavorable outcomes. METHODS: Istanbul-3 study evaluated 263 adult patients with CNS brucellosis from 26 referral centers and reviewed their 242 magnetic resonance imaging (MRI) and 226 computerized tomography (CT) scans of the brain. RESULTS: A normal CT or MRI scan was seen in 143 of 263 patients (54.3 %). Abnormal imaging findings were grouped into the following four categories: (a) inflammatory findings: leptomeningeal involvements (44), basal meningeal enhancements (30), cranial nerve involvements (14), spinal nerve roots enhancement (8), brain abscesses (7), granulomas (6), and arachnoiditis (4). (b) White-matter involvement: white-matter involvement (32) with or without demyelinating lesions (7). (c) Vascular involvement: vascular involvement (42) mostly with chronic cerebral ischemic changes (37). (d) Hydrocephalus/cerebral edema: hydrocephalus (20) and brain edema (40). On multivariate logistic regression analysis duration of symptoms since the onset (OR 1.007; 95 % CI 1-28, p = 0.01), polyneuropathy and radiculopathy (OR 5.4; 95 % CI 1.002-1.013, p = 0.044), cerebrospinal fluid (CSF)/serum glucose rate (OR 0.001; 95 % CI 000-0.067, p = 0.001), and CSF protein (OR 2.5; 95 % CI 2.3-2.7, p = 0.0001) were associated with diffuse inflammation. CONCLUSIONS: In this study, 45 % of neurobrucellosis patients had abnormal neuroimaging findings. The duration of symptoms, polyneuropathy and radiculopathy, high CSF protein level, and low CSF/serum glucose rate were associated with inflammatory findings on imaging analyses.

RESUMO

BACKGROUND: The aim of this study was to assess health-related quality of life (HRQOL) among chronic hepatitis B (CHB) patients in Turkey and to study related factors. METHODS: This multicenter study was carried out between January 01 and April 15, 2015 in Turkey in 57 centers. Adults were enrolled and studied in three groups. Group 1: Inactive HBsAg carriers, Group 2: CHB patients receiving antiviral therapy, Group 3: CHB patients who were neither receiving antiviral therapy nor were inactive HBsAg carriers. Study data was collected by face-to-face interviews using a standardized questionnaire, Short Form-36 (SF-36) and Hepatitis B Quality of Life (HBQOL). Values equivalent to p < 0.05 in analyses were accepted as statistically significant. RESULTS: Four thousand two hundred fifty-seven patients with CHB were included in the study. Two thousand five hundred fifty-nine (60.1 %) of the patients were males. Groups 1, 2 and 3, consisted of 1529 (35.9 %), 1721 (40.4 %) and 1007 (23.7 %) patients, respectively. The highest value of HRQOL was found in inactive HBsAg carriers. We found that total HBQOL score increased when antiviral treatment was used. However, HRQOL of CHB patients varied according to their socio-demographic properties. Regarding total HBQOL score, a higher significant level of HRQOL was determined in inactive HBV patients when matched controls with the associated factors were provided. CONCLUSIONS: The HRQOL score of CHB patients was higher than expected and it can be worsen when the disease becomes active. Use of an antiviral therapy can contribute to increasing HRQOL of patients.

RESUMO

AIMS: There is no report on the factors affecting the resolution of symptoms related to meningitis during treatment of tuberculous meningitis (TBM). Thus, we examined the factors associated with early therapeutic responses. MATERIALS AND METHODS: This multicenter study included 507 patients with microbiologically confirmed TBM. However, 94 patients eligible for the analysis were included in this study from 24 centers. Six out of 94 patients died and the statistical analysis was performed with 88 survivors. Early and late responder groups were compared in the statistical analysis. P < 0.05 were considered to show a significant difference. RESULTS: In the multivariate analysis, the presence of vasculitis (P = 0.029, OR = 10.491 [95% CI, 1.27-86.83]) was found to be significantly associated with a delayed fever response whereas hydrocephalus was associated with altered mental status for >9 days duration (P = 0.005, OR = 5.740 [95% CI, 1.68-19.57]). According to linear regression analysis, fever was significantly persisting (>7 days) in the presence of vasculitis (17.5 vs. 7, P< 0.001) and hydrocephalus (11 vs. 7, P = 0.029). Hydrocephalus was significantly associated with persisting headache (21 vs. 12, P = 0.025), delayed recovery of consciousness (19.5 vs. 7, P = 0.001), and a delay in complete recovery (21 vs. 14, P = 0.007) in the linear regression analysis. Following institution of treatment, the complaints seemed to disappear in up to 2 weeks among TBM survivors. CONCLUSIONS: In the absence of hydrocephalus or vasculitis, one week of anti-tuberculosis treatment seems to be adequate for the resolution of TBM symptoms. Hydrocephalus and vasculitis delay the resolution of TBM symptoms in response to antimycobacterial treatment.

RESUMO

BACKGROUND: Tuberculous meningitis (TBM) caused by Mycobacterium tuberculosis resistant to antituberculosis drugs is an increasingly common clinical problem. This study aimed to evaluate drug resistance profiles of TBM isolates in adult patients in nine European countries involving 32 centers to provide insight into the empiric treatment of TBM. METHODS: Mycobacterium tuberculosis was cultured from the cerebrospinal fluid (CSF) of 142 patients and was tested for susceptibility to first-line antituberculosis drugs, streptomycin (SM), isoniazid (INH), rifampicin (RIF) and ethambutol (EMB). RESULTS: Twenty of 142 isolates (14.1 %) were resistant to at least one antituberculosis drug, and five (3.5 %) were resistant to at least INH and RIF, [multidrug resistant (MDR)]. The resistance rate was 12, 4.9, 4.2 and 3.5 % for INH, SM, EMB and RIF, respectively. The monoresistance rate was 6.3, 1.4 and 0.7 % for INH, SM and EMB respectively. There was no monoresistance to RIF. The mortality rate was 23.8 % in fully susceptible cases while it was 33.3 % for those exhibiting monoresistance to INH, and 40 % in cases with MDR-TBM. In compared to patients without resistance to any first-line drug, the relative risk of death for INH-monoresistance and MDR-TBM was 1.60 (95 % CI, 0.38-6.82) and 2.14 (95 % CI, 0:34-13:42), respectively. CONCLUSION: INH-resistance and MDR rates seemed not to be worrisome in our study. However, considering their adverse effects on treatment, rapid detection of resistance to at least INH and RIF would be most beneficial for designing anti-TB therapy. Still, empiric TBM treatment should be started immediately without waiting the drug susceptibility testing.

RESUMO

We aimed to investigate the demographic, clinical, diagnostic, treatment and outcome features of patients with urinary tuberculosis (UTB). Patients with UTB admitted to seven separate centers across Turkey between 1995 and 2013 were retrospectively evaluated. The diagnosis of UTB was made by the presence of any clinical finding plus positivity of one of the following: (1) acid-fast bacilli (AFB) in urine, (2) isolation of Mycobacterium tuberculosis, (3) polymerase chain reaction (PCR) for M. tuberculosis, (4) histopathological evidence for TB. Seventy-nine patients (49.36% male, mean age 50.1 ± 17.4 years) were included. Mean time between onset of symptoms and clinical diagnosis was 9.7 ± 8.9 months. The most common signs and symptoms were hematuria (79.7%), sterile pyuria (67.1%), dysuria (51.9%), weakness (51.9%), fever (43%) and costovertebral tenderness (38%). Cystoscopy was performed in 59 (74.6%), bladder biopsy in 18 (22.8%), kidney biopsy in 1 (1.26%) and nephrectomy in 12 (15.2%) patients. Histopathological verification of UTB was achieved in 12 (63.1%) patients who undergone biopsy and in 100% of those undergone nephrectomy. Mycobacterium tuberculosis was isolated in the urine of 50 (63.3%) cases. Four-drug standard anti-TB treatment was the preferred regimen for 87.3% of the patients. Mean treatment duration was 10.5 ± 2.7 months. Deterioration of renal function occurred in 15 (18.9%) patients two of whom progressed to end-stage renal disease and received hemodialysis. Only one patient died after 74-day medical treatment period. Cases with UTB may present with non-specific clinical features. All diagnostic studies including radiology, cyctoscopy and histopathology are of great importance to exclude UTB and prevent renal failure.

RESUMO

CONTEXT: Anthrax is a rare disease cause by Bacillus anthracis, a Gram-positive, rod-shaped endospore-forming capsuled bacterium. Anthrax is manifest in three primary forms: cutaneous, respiratory, and gastrointestinal. Cutaneous anthrax accounts for approximately 95% of all cases of anthrax in humans. OBJECTIVE: In the present study, we evaluated the clinical diagnosis and treatment of cutaneous anthrax, a rare disease that nonetheless remains a serious healthcare problem in developing countries. METHODS: The complete medical records of patients diagnosed with cutaneous anthrax between January 2001 and December 2012 were examined in a retrospective manner. Cutaneous anthrax was diagnosed by the identification of typical anthrax lesions and/or the presence of Gram-positive-capsuled bacillus after staining with Gram stain and methylen blue in pathology samples obtained from these lesions and the presence of characteristic scarring with a history of severe swelling, black eschar, and positive response to treatment form the basis of diagnosis in cases where cultures were negative for the presence of bacillus. RESULTS: A total of 58 patients were admitted to the hospital with cutaneous anthrax between January 2001 and December 2012. This included 32 (55.2%) males and 26 (44.8%) females, with an age range of 15-82 years and a mean age of 38 ± 13.8 years. The incubation period for the infection ranged between 1 and 20 d (mean 3.7 ± 1.4 d). The most common symptoms at the time of hospital referral were swelling, redness, and black eschar of the skin. The most common lesion site was the hand and fingers (41.3%). Isolated of bacteria was used to diagnose the disease in six cases (23.8%), detection of Gram-positive bacillus in samples of characteristic lesion material was used in seven (28.5%) cases, and the presence of a characteristic lesion was the sole diagnostic criteria in 45 (77.6%) cases. Treatment consisted of penicillin G (12 cases), ampicillin-sulbactam (30 cases), Cefazolin (12 cases), or ciprofloxacin (4 cases). CONCLUSION: Although the prevalence of anthrax is a decreasing worldwide, it remains a significant problem in developing countries. Rapid identification of the signs and symptoms of cutaneous anthrax is essential for effective treatment. Early supportive treatment and appropriate antimicrobial measures are necessary to address this potentially life-threatening disease.

RESUMO

The aim of the present study was to identify nosocomial infections (NIs), and their associated risk factors, in patients treated in the neurosurgery intensive care unit (NICU) of our hospital. Patients determined to have NIs between January 2008 and December 2012 were included in the study. Each patient's age, gender, microbiological culture results, underlying conditions, type of NIs, device utilization, total parenteral nutrition, reason for hospitalization, Glasgow score, and treatment were recorded and evaluated using statistical analysis. Risk factors for NIs were analyzed with a logistic regression model. During the five-year period, 60 NI episodes were detected in 56 out of 1643 patients. The mean age of the patient population was 33.3 (1-79) years. Of the patients, 22 were female and 34 were male. The overall incidence rate (NIs/100) and incidence density (NIs /1000 days of stay) of NIs were 3.65% and 6.5/1000 patient days, respectively. Regardless of the year of surveillance, the three most commonly detected NIs were bloodstream infection, shunt infection, and ventilator-associated pneumonia. No statistically significant difference was detected between infected and uninfected patients in terms of sex, age, blood transfusions, or mannitol and steroid use (p ≥ 0.05). In the present study, Glasgow scores, the frequency of prior usage of broad-spectrum antibiotics, and NICU stay durations were significantly higher among patients with infections (p < 0.001). Univariate analysis demonstrated that a low Glasgow score, re-operation, and use of mechanical ventilation were risk factors for NIs. We identified low Glasgow coma scores, long hospital stay duration, use of wide spectrum antibiotics, mechanical ventilation, total parenteral nutrition, and re-operation as risk factors for NIs.

RESUMO

BACKGROUND: Delayed diagnosis and inadequate treatment of infectious and inflammatory diseases, such as Brucella, lead to high rates of mortality and morbidity. The aim of our study was to investigate the association between serum levels of apelin, presepsin, and irisin with inflammation, laboratory parameters, and blood culture in patients with brucella. PATIENTS AND METHODS: This prospective case-control study involves 30 patients with brucellosis and 30 healthy, matched control subjects. Thirty patients who were diagnosed with brucellosis were aged ≥ 18 years. Blood samples were taken from the patients on the first day they were diagnosed with brucellosis. The values of irisin, presepsin, and apelin were studied. In addition, blood samples were also taken from 30 healthy individuals for the control group. Irisin, presepsin, and apelin values that were measured in the patients on the first day were compared with those values measured in the control group. RESULTS: The sex and age statuses of the subjects are matched among the groups. The levels of irisin were significantly higher in patients with brucellosis compared to the control group (p<0.045). There was no significant difference between the two groups in terms of apelin and presepsin levels (p values 0.087 and 0.162, respectively). There was a positive correlation between irisin levels and elevated ALT levels, as well as positive blood cultures. CONCLUSIONS: It appears that the measurement of irisin levels may be beneficial in patients with brucellosis. Irisin can be used as a diagnostic marker for brucella infection and may greatly clinicians to predict the severity disease and treatment response.

RESUMO

Background: Blood culture-negative endocarditis (BCNE) is a diagnostic challenge, therefore our objective was to pinpoint high-risk cohorts for BCNE. Methods: The study included adult patients with definite endocarditis. Data were collected via the Infectious Diseases International Research Initiative (ID-IRI). The study analysing one of the largest case series ever reported was conducted across 41 centers in 13 countries. We analysed the database to determine the predictors of BCNE using univariate and logistic regression analyses. Results: Blood cultures were negative in 101 (11.65 %) of 867 patients. We disclosed that as patients age, the likelihood of a negative blood culture significantly decreases (OR 0.975, 95 % CI 0.963-0.987, p < 0.001). Additionally, factors such as rheumatic heart disease (OR 2.036, 95 % CI 0.970-4.276, p = 0.049), aortic stenosis (OR 3.066, 95 % CI 1.564-6.010, p = 0.001), mitral regurgitation (OR 1.693, 95 % CI 1.012-2.833, p = 0.045), and prosthetic valves (OR 2.539, 95 % CI 1.599-4.031, p < 0.001) are associated with higher likelihoods of negative blood cultures. Our model can predict whether a patient falls into the culture-negative or culture-positive groups with a threshold of 0.104 (AUC±SE = 0.707 ± 0.027). The final model demonstrates a sensitivity of 70.3 % and a specificity of 57.0 %. Conclusion: Caution should be exercised when diagnosing endocarditis in patients with concurrent cardiac disorders, particularly in younger cases.

RESUMO

CONTEXT: Anthrax is a rare disease caused by Bacillus anthracis. Antrax is zoonotic disease and is often encountered in persons engaged in animal husbandry. Cutaneous anthrax is approximately 95% of anthrax in humans. Palbebral involvement is rare. OBJECTIVE: In this study, we aimed to evaluate the clinical presentation, diagnosis and treatment of cases with cutaneous palpebral anthrax. METHODS: In this study, the patients diagnosed of cutaneous palpebral anthrax between January 2000 and December 2012, were investigated and evaluated, retrospectively. Cutaneous palpebral anthrax was diagnosed by the presence of typical anthrax lesion and/or observation of gram-positive encapsulated bacilli in gram prepations and/or culture positive of samples taken from lesions. In the cases who were culture-negative and without bacilli in gram-staining, the diagnosis was based on the presence of characteristic clinical presentation with a history of severe scarring formation, swelling, black eschar and positive response to the treatment. RESULTS: A total of 21 patients with cutaneous palpebral anthrax admitted to the two hospitals between January 2000 and December 2012. Eight patients were male (38.1%) and 13 patients were female (61.9%), and the mean age was 31 ± 21.2 (range 1-82 years). The most common symptoms on admission to the hospital were swelling and redness on the skin. Periorbital lesions were in the right eye in 14 cases and the most common eyelid involvement was seen in upper eyelid with 15 cases. The diagnosis was based on isolation of bacteria in five (23.8%) cases, detection of gram-positive bacilli in direct examination of characteristic lesion material in six (28.5%) cases. Ten (47.7%) cases were diagnosed by the characteristic appearance of the lesion. Malignant pustule was seen in all of our patients and seven cases (33.4%) had malignant edema. In the treatment, penicilin was used for 10 (47.7%) cases, ampicillin-sulbactam for five (23.8%) cases and, ciprofloxacin for three (14.3%) cases. Cicatricial ectropion was observed in 10 (47.7%) patients, lagophthalmos developed in four (19%) patients, and corneal scar in two (9.5%) patients. The distribution of the cases did not differ by the year but showed a density in the months from July to September (62.7%). CONCLUSION: Early diagnosis and high dose antibiotic treatment can facilitate the treatment and prevent development of eyelid complications including cicatricial ectropion, corneal scars and palpebral symphysis. Prolonged follow-up is necessary in patients who develop complications and surgical intervention.

RESUMO

BACKGROUND: We have evaluated urinary tract infections (UTI) in neonatal indirect hyperbilirubinemia. Urine culture is not routinely requested in patients with indirect hyperbilirubinemia. However, debates continue about the frequency and investigation of UTI in neonatal indirect hyperbilirubinemia patients. The aim of this study was to determine the prevalence of UTI in neonates admitted to the hospital due to pathological indirect hyperbilirubinemia and whether a routine urine culture test is necessary in patients. METHODS: In this retrospective study, we analyzed data from 1390 patients hospitalized to the Neonatal Unit due to pathological indirect hyperbilirubinemia. One hundred and eleven of these patients with detected bacterial agents in the urine cultures were evaluated. The type of the pathogens grown in urine culture, the number of colonies, and the antibiotic resistance status were evaluated. RESULTS: Among 1390 patients screened, 111 (8%) were found to have UTI, 68 of whom (61.3%) were male. Out of the microorganisms that grew, Escherichia coli was the dominant microorganism with 36.1%, which was followed by Klebsiella species (23.4%), and Enterococcus species (18%), respectively. CONCLUSIONS: The prevalence of UTI is high in the neonatal period as in all childhood and especially in patients admitted to the Neonatal Unit due to indirect hyperbilirubinemia. Escherichia coli and Klebsiella species are the most common bacterial agents that grow. Missing the diagnosis of urinary tract infection in neonates may cause renal problems. Therefore, we recommend requesting a urine culture in routine examinations of neonates who are diagnosed with pathological indirect hyperbilirubinemia and admitted to the hospital due to the need for phototherapy.

RESUMO

INTRODUCTION: This study aims to research the effects of hematological and inflammatory parameters on the prognosis of COVID-19 disease and hospitalization duration. METHODOLOGY: One hundred and eighty-six patients with COVID-19 and a control group consisting of 187 healthy individuals were included in the study. Hematological variables and inflammatory parameters of the patients were recorded on the first and the fifth days of hospitalization. RESULTS: White blood cell count, lymphocyte count, and platelet count were statistically lower, and mean platelet volume (MPV), neutrophil to lymphocyte ratio (NLR), and platelet to lymphocyte ratio (PLR) levels were higher in the patient group compared to the control group. It was observed that the neutrophil count and MPV level were lower, and the platelet count and ferritin level were statistically higher on the fifth day of follow-up compared to the admission day. In contrast, there was a significantly positive correlation between the duration of hospitalization and the fifth day D-dimer (r = 0.546, p < 0.001) and ferritin (r = 0.568, p < 0.001); in addition, there was a negative correlation between the duration of hospitalization and admission day lymphocyte count and the fifth-day lymphocyte count. CONCLUSIONS: Increased levels of ferritin and D-dimer, and decreased count of lymphocytes are among the important factors affecting the duration of hospitalization for COVID-19 patients. Furthermore, we think that neutrophil count and MPV levels are low, and platelet count and ferritin levels are high during the disease. Therefore, these parameters can be used as prognostic indicators of the disease.

RESUMO

BACKGROUND: Mucormycosis is an emerging aggressive mold infection. This study aimed to assess the outcome of hospitalized adults with rhino-orbito-cerebral mucormycosis (ROCM). The secondary objective was to identify prognostic factors in this setting. METHODS: This study was an international, retrospective, multicenter study. Patients' data were collected from 29 referral centers in 6 countries. All qualified as "proven cases" according to the EORTC/MSGERC criteria. RESULTS: We included 74 consecutive adult patients hospitalized with ROCM. Rhino-orbito-cerebral type infection was the most common presentation (n = 43; 58.1%) followed by rhino-orbital type (n = 31; 41.9%). Twenty (27%) had acquired nosocomial bacterial infections. A total of 59 (79.7%) patients (16 in combination) received appropriate antifungal treatment with high-doses of liposomal amphotericin B. Fifty-six patients (75.7%) underwent curative surgery. Thirty-five (47.3%) required intensive care unit admission (27; 36.5% under mechanical ventilation). Hospital survival was 56.8%, being reduced to 7.4% in patients with invasive mechanical ventilation. A multivariate binary backward logistic regression model identified confusion at admission (OR 11.48), overlapping hospital-acquired infection (OR 10.27), use of antifungal treatment before diagnosis (OR 10.20), no surgical debridement (OR 5.92), and the absence of prior sinusitis (OR 6.32) were independently associated with increased risk for death. CONCLUSION: Today, ROCM still has high mortality rate. Improving source control, rational therpy, and preventing nosocomial infections may improve survival in this severe infection.

RESUMO

INTRODUCTION: Although vaccines are the safest and most effective means to prevent and control infectious diseases, the increasing rate of vaccine hesitancy and refusal (VHR) has become a worldwide concern. We aimed to find opinions of parents on vaccinating their children and contribute to available literature in order to support the fight against vaccine refusal by investigating the reasons for VHR on a global scale. METHODOLOGY: In this international cross-sectional multicenter study conducted by the Infectious Diseases International Research Initiative (ID-IRI), a questionnaire consisting of 20 questions was used to determine parents' attitudes towards vaccination of their children. RESULTS: Four thousand and twenty-nine (4,029) parents were included in the study and 2,863 (78.1%) were females. The overall VHR rate of the parents was found to be 13.7%. Nineteen-point three percent (19.3%) of the parents did not fully comply with the vaccination programs. The VHR rate was higher in high-income (HI) countries. Our study has shown that parents with disabled children and immunocompromised children, with low education levels, and those who use social media networks as sources of information for childhood immunizations had higher VHR rates (p < 0.05 for all). CONCLUSIONS: Seemingly all factors leading to VHR are related to training of the community and the sources of training. Thus, it is necessary to develop strategies at a global level and provide reliable knowledge to combat VHR.

RESUMO

INTRODUCTION: This study aimed to evaluate and compare with healthy control subjects the levels of indirect inflammatory markers such as mean platelet volume (MPV), platelet to lymphocyte ratio (PLR), and neutrophil to lymphocyte ratio (NLR) in adults and children with brucellosis. METHODS: White blood cell, neutrophil, lymphocyte, and platelet counts, and C-reactive protein (CRP) levels were retrospectively recorded for all participants. RESULTS: NLR and neutrophil counts were significantly higher in adult patients compared to those in pediatric patients. CONCLUSIONS: Indirect inflammatory markers such as NLR, PLR, MPV, red distribution width, and CRP levels may be helpful for follow-up of brucellosis.
