Comparison of Inflammatory Markers between Adult and Pediatric Brucellosis Patients

Abstract 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.

Volumen plaquetario medio, índice de neutrófilos/linfocitos e índice de trombocitos/linfocitos para determinar el diagnóstico y/o pronóstico en niños con mordedura de serpiente / Mean platelet volume, neutrophil to lymphocyte ratio and platelet to lymphocyte ratio in determining the diagnosis or outcome in children with snakebite

Objetivo.Evaluar la relación entre las variables de volumen plaquetario medio (VPM), índice de neutrófilos/linfocitos (INL) e índice de trombocitos/linfocitos (ITL) y el diagnóstico o la predicción del desenlace en los niños con intoxicación por mordedura de serpiente. Métodos.Se realizó una evaluación retrospectiva de niños con diagnóstico de intoxicación por mordedura de serpiente y un grupo de referencia de sujetos sanos. Se clasificó a los pacientes en tres grupos de intoxicación: leve, moderada y grave. Resultados.Se incluyeron 142 niños en el estudio. La leucocitosis (p= 0, 003), la neutrofilia (p= 0, 026) y la trombocitopenia (p= 0, 034) fueron significativamente más frecuentes en los casos de intoxicación por mordedura de serpiente grave; sin embargo, no se hallaron diferencias estadísticamente significativas en relación con el VPM, el INL y el ITL entre los diferentes grupos de intoxicación por mordedura de serpiente. La media del VPM, el INL y el ITL era significativamente mayor entre los niños con mordedura de serpiente en comparación con los controles sanos. Conclusiones.Según nuestros resultados, el uso del VPM, el INL y el ITL podría servir para el diagnóstico como marcadores inflamatorios en los casos de intoxicación por mordedura de serpiente.

Background: The objective of this study is to evaluate the relationships between the mean platelet volume (MPV), neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) variables and diagnosis or prediction of outcome in children with snakebite envenomation. Methods: Children diagnosed with snakebite envenomation and a control group of healthy subjects were retrospectively evaluated. Patients were classified into three groups as mild, moderate and severe. Results: 142 children were enrolled in the study. Leukocytosis (p= 0.003), neutrophilia (p= 0.026) and thrombocytopenia (p= 0.034) were significantly more common in severe snakebite envenomation, although no statistical significant were found in association with MPV, NLR and PLR between snakebite envenomation groups. The mean MPV, NLR and PLR were found to be significantly higher in children with snakebite compared to than among healthy controls. Conclusions: Our results suggested that MPV, NLR and PLR may be useful for the diagnosis as inflammatory markers in snakebite envenomation.

Comparison of culture and PCR methods in the diagnosis of bacterial meningitis

Abstract Our aim in this study is to compare the standard culture method with the multiplex PCR and the Speed-Oligo® Bacterial Meningitis Test (SO-BMT) – a hybridization-based molecular test method – during the CSF examination of the patients with the pre-diagnosis of acute bacterial meningitis. For the purposes of this study, patients with acute bacterial meningitis treated at the Dicle University Medical Faculty Hospital, Infectious Diseases and Clinical Microbiology Clinic between December 2009 and April 2012 were retrospectively evaluated. The diagnosis of bacterial meningitis was made based on the clinical findings, laboratory test anomalies, CSF analysis results, and the radiological images. Growth was observed in the CSF cultures of 10 out of the 57 patients included in the study (17.5%) and Streptococcus pneumoniae was isolated in all of them. The CSF samples of 34 patients (59.6%) were positive according to the SO-BMT and S. pneumoniae was detected in 33 of the samples (97.05%), while Neisseria meningitidis was found in 1 sample (2.95%). In a total of 10 patients, S. pneumoniae was both isolated in the CSF culture and detected in the SO-BMT. The culture and the SO-BMT were negative in 23 of the CSF samples. There was no sample in which the CSF culture was positive although the SO-BMT was negative. While SO-BMT seems to be a more efficient method than bacterial culturing to determine the pathogens that most commonly cause bacterial meningitis in adults, further studies conducted on larger populations are needed in order to assess its efficiency and uses.

Candida arthritis in a patient diagnosed with spondyloarthritis

Abstract Candida arthritis is an unusual manifestation that usually affects the knees. A 35-year-old man presented with a 2-month history of pain and swelling in the right knee. Swelling persisted after anti-inflammatory treatment. Peripheric spondyloarthritis was considered, but methotrexate, sulfasalazine, and methylprednisolone did not reduce the swelling. Direct examination of synovial fluid and a culture were positive for Candida albicans. Intravenous and intra-articular amphotericin-B were administered. The arthritis regressed and a culture and direct staining showed negative results. Candida arthritis should be considered in patients with arthritis that is resistant to treatment and prolonged, even if risk factors are absent.

Rabdomiólisis recurrente en un niño: Presentación de un caso / Recurrent rhabdomyolysis in a child: Case presentation

La miositis viral asociada a infecciones raramente produce rabdomiólisis. En las publicaciones científicas no se describe ningún caso pediátrico de rabdomiólisis grave recurrente inducida por infecciones. En este artículo presentamos el caso de un niño de sexo masculino de dos años de edad hospitalizado en tres ocasiones debido a rabdomiólisis grave asociada a miositis viral durante el invierno. Esta es la primera presentación de un caso pediátrico de rabdomiólisis grave inducida por infecciones. En este paciente, el tratamiento con prednisolona e inmunoglobulinas por vía i.v. fue ineficaz.

Viral myositis associated with infections rarely may cause rhabdomyolysis. There is no any pediatric case with severe recurrent rhabdomyolysis triggered by infections in the literature. We reported a two-year-old boy who was hospitalized three times due to severe rhabdomyolysis associated with viral myositis in the winter months. This is the first child case presentation with severe rhabdomyolysis triggered by infections. Prednisolone and intravenous immunoglobulin treatments were ineffective in this case.

Relationship between HBV DNA Positivity and Migraine in Patients with Chronic Hepatitis.

Purpose: Migraine headache is one of the oldest diseases known to mankind, affecting thousands of people throughout the world. The objective of this study is to compare the frequency of migraines in the patient group previously diagnosed with chronic hepatitis-B to the migraine frequency in the healthy control group. Materials and Methods: Patients who presented to Dicle University Hospital and who were diagnosed with chronic hepatitis-B were enrolled in the study. The viral hepatitis markers, aspartate aminotransferase (AST), alanine aminotransferase (ALT), hepatitis-b virus DNA (HBV DNA), and their levels were included in the evaluation. The control group consisted of healthy individuals with no hepatitis-B detected in the previous screenings. Chronic fatigue observed in the patient group was recorded, and the degree of fatigue was assessed according to the Visual Analogue Scale to Evaluate Fatigue Severity (VAS-F). Approval of the local ethics committee was obtained for this study. Results: The frequency of migraines in patients who tested positive for HBV DNA was significantly higher than in those who tested negative for HBV DNA (p<0.05). Chronic fatigue was also significantly higher in the study group compared to the control group (p=0.01), and their HBV DNA levels were correlated with the VAS-F score (r=0.532; p<0.001). Conclusion: Migraine was found to be correlated with fatigue and the HBV DNA ratio in chronic hepatitis B patients.

Hydatid cysts in muscles: clinical manifestations, diagnosis, and management of this atypical presentation

ABSTRACTINTRODUCTION: Hydatid cysts are rarely detected in muscle tissue (0.7-0.9%), even in endemic countries. The aim of this study was to present information regarding the clinical manifestations, diagnosis, and management of muscle echinococcosis.METHODS: Twenty-two patients with hydatid cysts in the muscle were followed from January 2006 through December 2014.RESULTS: Twenty-four sites of muscle involvement were observed in the 22 patients. Fifteen (68%) of our patients were women, while seven (32%) were men. The mean age was 28.1 ± 15.4 (6-61) years. The most frequent locations were the thigh (27.2%) and the paravertebral region (13.6%). Most patients reported a painless slow-growing mass with normal overlying skin. Most (90.2%) cases were treated by surgical excision and fine-needle aspiration.CONCLUSIONS: Primary muscle hydatid cyst should be considered in the differential diagnosis in cystic masses of the muscular system without pain and localized enlargement of soft tissue, especially in endemic areas. Hydatid cyst should be investigated using serological tests and imaging modalities. If possible, total surgical excision of hydatid cyst in the muscle should be performed.

Molecular epidemiology of HIV-1 strains in the south-east and east of Turkey

To detect the subtype characterization and drug-resistant mutations in HIV-1 strains after the refugee movement from Syria to Turkey between 2011 and 2014 in south east border lines. Methods: A total of 65 patients were included in this study, of which 57 (88%) patients were antiretroviral therapy-naive patients. HIV-1 RNA was detected and quantified by real-time PCR assay. HIV-1 subtypes and circulating recombinant forms (CRFs) were identified by phylogenetic analysis (neighbor-joining method), and drug-resistant mutations were analyzed. Results: Three major HIV groups were indicated. Two of these groups were located in subtype B. The other group showed heterogeneity. Subtype B (48/65, 73.8%), followed by CRFs (12/65, 18.5%) was the most common strain. Subtype of CRFs consisted of CRF01_AE (9/65, 13.8%) and CRF02_AG (3/65, 4.6%). Subtype C (1/65, 1.5%), sub-subtypes A1 (2/65, 3.1%) and F1 (2/65, 3.1%) were also detected with low prevalence. The rate of overall primary antiretroviral resistance was 4.9% (3/61). Drug-resistant rate for non-nucleoside reverse transcriptase inhibitors was 4.9%. The thymidine analogue mutation rate was 13.1% (8/61). Conclusions: HIV molecular epidemiology studies are necessary to determine transmission patterns and spread. Subtype B and CRF01_AE, CRF02_AG are the most prevalent strains in the south-east of Turkey. However, subtype C, sub-subtypes A1 and F1 are of low prevalence but persist in the south-east of Turkey. In the near future, changing of HIV epidemiology will be possible in Turkey due to migration movement in border lines and resistance testing will play an important role in HIV management.

In vitro susceptibility to methicillin, vancomycin and linezolid of staphylococci isolated from bloodstream infections in eastern Turkey

Staphylococcus species are one of the major causes of bacterial bloodstream infections. Multi-resistant staphylococci infections are major therapeutic problems. This study was aimed to detect methicillin, linezolid and vancomycin susceptibilities of Staphylococcus isolates. A total of 870 Staphylococcus strains isolated from blood cultures of hospitalized patients with BSI. Antimicrobial susceptibilities of methicillin, linezolid and vancomycin were detected according to the Clinical and Laboratory Standards Institute (CLSI). A total of 771 (88.6%) isolates were coagulase-negative staphylococci (CoNS). 700 (80.5%) isolates were methicillin-resistant (MR) and 170 (19.5%) were methicillin-susceptible (MS). All the MS isolates were also susceptible to linezolid. However 15 (1.7%) of MR strains were resistant to linezolid. The minimum inhibitory concentration range for the linezolid-resistant isolates by Etest was 6-32 µg/mL. The difference between linezolid susceptibilities for MS and MR staphylococci was not quite statistically significant (p = 0.052). There was no statistically significant difference between S. aureus and CoNS isolates for linezolid susceptibility. All of the isolates were susceptible to vancomycin. In conclusion, linezolid is currently an efficient option for the treatment of methicillin-resistant staphylococci infections.
