Adverse effects of single-component measles vaccine in school children.

Measles is a highly contagious viral infection potentially with serious complications and the principal method of protection from the disease is vaccination. Measles vaccination resulted in a 79% drop in measles deaths between 2000 and 2015 worldwide. There has long been a debate about the necessity and benefit-loss ratio of routine MMR vaccination due to possible AE of MMR vaccine. Especially in developed countries which are thought to be free of measles there is an increasing tendency towards hesitation for vaccination though there have been continued outbreaks of measles in countries in which measles is considered to be eliminated. Considering those facts, we decided to publish our data about measles vaccination and adverse effects (AE) during national catch-up measles vaccination programme which took place December 8-26, 2003. A total of 152.648 children aged between seven and fourteen were vaccinated by a live attenuated measles vaccine of which 148.064 (97%) had received measles vaccine by age nine or twelve months. During one month follow-up the AE were recorded. Totally 30.302 AE were reported in 24.209 children, of which 52% of them were local and pain and swelling at injection side were the most common AE. Fever and headache were the most commonly observed systemic side effects. All AE were mild and transient except in four children in whom encephalitis was diagnosed during the one month observation period. Further investigation of the etiology of those cases revealed that they were not related to measles or measles vaccine. In conclusion, single-component measles vaccine was found to be safe in previously MMR vaccinated children in short term and long term effects may be need to be clarified by further studies.

[Septic arthritis of hip due to Salmonella Typhi in a patient with multiple sclerosis]. / Multipl Sklerozlu Bir Olguda Salmonella Typhi'ye Bagli Kalça Eklemi Artriti.

The most common microorganisms isolated from septic arthritis are Staphylococcus aureus and streptoccocci. Septic arthritis due to Salmonella spp. are rare and the most commonly isolated species are S.Choleraesuis and S.Typhimurium. However the number of septic arthritis cases due to S.Typhi is low in literature. In this report, septic arthritis of hip due to S.Typhi in a multiple sclerosis patient who was under steroid therapy, was presented. A 25-year-old female patient was admitted to our clinic with the complaints of fever, left hip pain, standing and walking disability for 10 days. Her anamnesis revealed that she had had a multiple sclerosis attack and underwent triple pulse steroid therapy. Laboratory findings were as follows; WBC count: 16.300/mm3 (70% polymorphonuclear leukocyte), hemoglobin: 10.6 g/dl, erythrocyte sedimentation rate: 140 mm/hour, CRP: 28.7 g/L, AST: 86 U/L and ALT: 77 U/L. In lumbosacral magnetic resonance imaging, trochanteric bursitis and generalized myositis were detected in left hip joint compatible with septic arthritis. S.Typhi was isolated from patient's blood and operational tissue samples. Serum Salmonella TO and TH titers were found as 1/400 and 1/200, respectively. Antibiotic susceptibility test was performed by disk diffusion method, and the isolate was found susceptible to ampicillin, chloramphenicol, ceftriaxone, ciprofloxacin and trimethoprim-sulphametoxazole. The patient was treated by surgery and also by two weeks parenteral (2 x 400 mg) and 6 weeks oral (2 x 500 mg) ciprofloxacin treatment. Six months follow-up of the patient revealed that clinical, radiological and laboratory findings were normal. As far as the national literature was considered, this was the first S.Typhi septic arthritis case involving the hip joint and demonstrating bacterial growth both in blood and operational tissue. The presentation of the infection as arthritis plus diffuse myositis and bursitis, is also noteworthy.

Hospital acquired infections (HAI) in the elderly: comparison with the younger patients.

The aim of this retrospective study is to determine the frequency, type, microbiological characteristics and outcome of HAIs in the elderly (age ≥ 65) and to compare the data with younger patients in a Turkish Training and Research Hospital. From January 2008 to December 2009, the infection control team analyzed HAIs among 60,585 hospitalized patients (20,109 aged ≥ 65 and 40,747 aged between 18 and 64 years) with a total number of 419,017 patient days. A total of 825 HAIs episodes were detected in 607 patients, of which 395 episodes were in 301 elderly patients. The incidence of HAIs per 1000 patient days was 2.49 in the elderly and 1.64 in the younger patients' group (p<0.001). The most common site of infection in the elderly patients was the urinary tract, whereas in non-elderly group this was the lower respiratory tract. The incidence density of urinary tract infections, respiratory tract infections, surgical site, skin and soft tissue infections, primary bacteremia, and prosthesis infections were significantly higher in the elderly group (p<0.05). Gram-negative species were the most frequently isolated agents in both groups. There were no significant differences between the groups in the frequency of isolated pathogens or antibiotic susceptibility patterns. Overall, the fatality rate was found 16.8%. The elderly patients were more likely to have crude mortality rates (22% vs. 12%; p<0.01). The death was most often related to pneumonia, primary bacteremia or intravascular catheter infections in both groups.

Clinical, diagnostic and therapeutic approaches to complications of brucellosis: an experience of 12 years.

OBJECTIVE: To describe the clinical presentations, laboratory findings, prevalence and pattern of complications and the response to treatment of brucellosis in a 12-year period in a Turkish research hospital. MATERIALS AND METHODS: Between 1996 and 2008, 231 patients were diagnosed with brucellosis and treated in our clinic. Medical records of 189 of the 231 patients with at least one demonstrable complication of the disease were reviewed for anamnesis, diagnosis, complications, treatment and clinical outcomes. RESULTS: The decreasing order of the complications was: hematological, 104 (55%); osteoarticular, 70 (37%); hepatobiliary, 59 (31%), and gastrointestinal, 23 (12%). The most common laboratory findings were anemia, lymphomonocytosis, elevated sedimentation rate and C-reactive protein, and elevated aminotransaminases. CONCLUSION: The hematological, osteoarticular and hepatobiliary manifestations were predominant. Bursitis, synovitis, glomerulonephritis, cutaneous lesion and deep vein thrombosis were the rare complications observed in our study. In clinical practice, brucellosis should be considered in the differential diagnosis in the presence of infrequent complications.

[The follow-up of serum aminotransferase levels and investigation of hepatitis B virus load in inactive HBsAg carriers]. / Inaktif HBsAG tasiyicilarinda serum alanin aminotransferaz izlemi ve hepatit B virus yükünün arastirilmasi.

The aim of this study was to follow-up the serum alanine aminotransferase (ALT) levels in inactive HBsAg carriers during one year period and investigate the association between hepatitis B virus (HBV) DNA levels detected at the end of the year. At May 2005, 61 patients with HBeAg negative/anti-HBe positive chronic HBV infection, followed in our viral hepatitis clinic were included to the study. The patients' ultrasonographic examination of the liver were normal, they had no history of taking alcohol or routine medication, were anti-HCV seronegative and had normal ALT levels during the last 6 months and at the beginning of the study. Serum ALT levels of patients were followed in the 3rd, 6th and 12th months of the study, and blood HBV-DNA levels were analysed quantitatively in 12th month. During the one year period 89% (54/61) of the patients yielded continously normal ALT levels, while 11% (7/61) showed at least one ALT value above the normal levels (ALT > 1.2x). Total HBV-DNA positivity rate was found as 59% (36/61). In inactive HBsAg carrier group,--namely HBeAg negative and serum ALT levels constantly normal--57.4% (31/54) of patients were HBV-DNA positive and 23 (42.6%) were negative. Amongst the HBV-DNA positive patients the viral load were detected as 10(4)-10(5) copies/ml in six (19.4%), and <10(4) copies/ml in 25 (80.6%) patients. In patients who had at least one ALT value above normal limits, 71.4% (5/7) of them were found HBV-DNA positive; two with HBV-DNA values of >10(5) copies/ml and three with values between 10(4)-10(5) copies/ml. In conclusion, although ALT levels may be normal, it should always be taken into consideration that more than half of inactive HBsAg carriers exhibited low level viral replication, thus HBV-DNA and liver enzyme levels should be monitored routinely in order not to miss the acute manifestations.

Early prosthetic valve endocarditis due to Acinetobacter baumannii: a case report and brief review of the literature.

Acinetobacter is a highly resistant microorganism, commonly isolated in intensive and post-operative care units. Although rarely reported, it may constitute 1 of the several causes of early prosthetic valve endocarditis. A diffuse, red maculopapular rash may be encountered in patients with Acinetobacter endocarditis. Here we present a case of early prosthetic valve endocarditis due to Acinetobacter baumannii and accompanied by a cutaneous eruption.

[Human herpesvirus-8 DNA in patients with certain demyelinating disorders]. / Demyelinizasyonla karakterize bazi hastaliklarda insan herpesvirus-8 DNA varliginin arastirilmasi.

Infectious etiology of the demyelinating diseases is an intensive matter of research. Among the suspected pathogens, herpesviruses had attracted particular attention because of their capacity to remain latent in nervous tissues, axonal transportation of some members within neurons, relapsing-remitting characteristic of the infections, and capability of inducing demyelination both in human host and animal models. Human herpesvirus-8 (HHV-8) is the least studied of this group even some of the HHV-8 related disorders such as HIV associated Castleman's disease, some lymphomas, monoclonal gammopathy of uncertain significance (MGUS), may be seen in patients with demyelinating conditions. The aim of this study was the investigation of a probable relationship between HHV-8 infection and certain demyelinating diseases. For this purpose, the presence of HHV-8 DNA has been investigated by polymerase chain reaction in the blood samples of 14 multiple sclerosis (MS), six chronic inflammatory demyelinizing polyneuropathy (CIDP), three Guillain-Barre syndrome (GBS), and one Miller-Fisher syndrome patients, together with 24 age- and sex-matched healthy subjects as control. As a result, one of MS, two of CIDP and all of the GBS patients were found HHV-8 DNA positive, whereas all the subjects in control group were negative. Although the interpretation of the results of this study does not seem to be possible owing to the limited number of patients, it emphasizes the need for larger scale, detailed studies on this subject since no other report dealing with this matter has been encountered in the literature.
