99mTc-HMPAO labelled leucocyte scintigraphy in the diagnosis of pelvic inflammatory disease.

BACKGROUND: Scintigraphy using leucocytes labelled with 99mTc hexamethylpropyleneamine oxime (99mTc-HMPAO) is widely used for the localization of inflammatory foci and abscesses in cases of acute pelvic inflammatory disease, which is one of the serious health problems of women of child-bearing age. Early diagnosis and effective management of this condition can preserve fertility and prevent serious complications, such as peritonitis and sepsis. AIM: To evaluate the importance of scintigraphy using 99mTc-HMPAO labelled leucocytes in the early diagnosis of patients with pelvic inflammatory disease. METHODS: Fifteen women (mean age 29.2+/-8 years, range 25-46 years) with suspicion of pyogenic pelvic inflammatory disease based on gynaecological examinations, clinical findings and blood tests were included in this study. The patients received 555 MBq 99mTc-HMPAO labelled leucocytes, by injection, and were scanned by scintigraphy 0.5-1, 3 and 24 h later in the anterior abdominal projection. Ten of the patients were then evaluated by abdominal or transvaginal ultrasonography, four by computed tomography and two by both ultrasound and computed tomography. The final diagnosis was made by surgical intervention. RESULTS: Scintigraphy detected pelvic inflammatory disease in five of the patients. In three of them the disease was apparent on the scans taken at 0.5-1 h, and in the other two it was apparent at 3 h. There were no false negative results, and one false positive result. The scan accurately reflected the absence of pelvic inflammatory disease in nine patients showing non-pathological tracer uptake in the lower abdominal region. CONCLUSION: We showed that scintigraphy with 99mTc-HMPAO labelled leucocytes had a sensitivity of 100%, specificity of 90%, overall accuracy of 93%, positive predictive value of 83%, and negative predictive value of 100%. Therefore, we conclude that 99mTc-HMPAO labelled leucocyte scans provide a rapid and highly accurate method for diagnosing pelvic inflammatory disease in women of child-bearing age. This adds an important contribution to the diagnosis of infection and helps determine further operative or conservative treatment.

[A transfusion-transmitted malaria case].

Malaria is a rare but potentially serious complication of blood transfusion. In this report a transfusion-transmitted malaria case has been presented. A 47-years-old woman admitted to our clinic with the complaints of striking fever with chills, diarrhea and vomiting. She had history of an operation and transfusion before 10 days of admission. On physical examination jaundice, splenomegaly and abdominal tenderness were detected. Laboratory results revealed anemia, and elevated LDH and bilirubin levels. Examination of thin blood films yielded Plasmodium vivax trophozoites. Chloroquine was initiated for therapy and the patient was successfully treated. On the other hand, informations about her blood donor indicated that he had been in the military service in Southeast Anatolia of Turkey where malaria is endemic. All the efforts to reach the donor, for his diagnosis and treatment, were failed. Since our region (Northeast Anatolia) is not an endemic area for malaria and the patient had no travel history to an endemic area, it has been considered that the transmission route of malaria in this case was blood transfusion. In conclusion, as there are no available approved tests for malaria screening of donations, the transfusion-transmitted malaria can only be prevented by careful questioning of the donors.

Nosocomial methicillin-resistant Staphylococcus aureus endocarditis with splenic abscess in a pregnant woman.

A 36-year-old, 7-week-gravida patient with catheter-related nosocomial infective endocarditis due to methicillin-resistant Staphylococcus aureus (MRSA) is presented in this paper. The patient was admitted to our hospital because of carbon monoxide intoxication. After 14 days, MRSA catheter-related bacteremia developed. The central venous catheter was immediately removed, and teicoplanin therapy was started. Because of persistent fever, leukocytosis, and high C-reactive protein values, endocarditis was suspected. A transesophageal echocardiogram revealed 19-mm vegetation on her mitral valve, confirming the diagnosis of endocarditis. Gentamicin and rifampicin were added to the therapy regimen, and the dose of teicoplanin was increased to 12 mg/kg-day. After 8 days, a splenic abscess was detected by ultrasonography. Vegetation excision, mitral valve replacement by open-heart surgery and splenectomy were performed in the same operation. Antibiotherapy was continued for 6 weeks after surgery, and the patient's condition improved. The development of endocarditis could be prevented by proper clinical practices.

Changes in antibiotic use, cost and consumption after an antibiotic restriction policy applied by infectious disease specialists.

The study was designed to compare antibiotic use, cost and consumption before and after an initiation of an antibiotic-restriction policy in our hospital. The policy was applied in 2003, and the prescription of two groups of antibiotics (intravenously used and expensive antibiotics) was restricted. A prescription for the restricted antibiotics could be obtained with approval by an infectious disease specialist (IDS). All the hospitalized patients who received antibiotics were evaluated by a cross-sectional study with standard criteria. The annual cost and consumption of antibiotics were evaluated. After restriction, the rate of antibiotic use decreased from 52.7 to 36.7% (P < 0.001), and the appropriate use increased from 55.5 to 66.4% (P < 0.05). Appropriate use was higher for restricted antibiotics (88.4%) than for unrestricted ones (58.2%) (P < 0.001), and higher in the presence of ID consultation (97.5%) than in the absence of consultation (55.7%) (P < 0.001). Culture-based treatment was increased, and appropriate use in such cases (93.0%) was higher than empirical treatment (33.3%) (P < 0.001). After the restriction policy, consumption of antibiotics belonging to the restricted groups was decreased by 44.8%. Total expenditure of all antibiotics was decreased by 18.5%, and the savings were US$332,000 per year. This restriction policy was effective in promoting rational antibiotic prescription and lowering antibiotic cost and consumption in our hospital.

The time-related changes of antimicrobial resistance patterns and predominant bacterial profiles of burn wounds and body flora of burned patients.

To examine the bacterial isolates from the burn patients and to compare the antibiograms of the predominant bacteria isolated from 51 patients who were hospitalized at least 3 weeks or more over a period of 7 months, a prospective study was undertaken. Periodic swabs were taken from burn wound, nasal, axillary, inguinal, and umbilical region of the patients on admission and on 7th, 14th, and 21st days of hospitalization. Mean hospital stay was 36.5 days. A total of 1098 microbial isolates were detected during the study period. Coagulase-negative staphylococci (CNS, 63.0%) and Staphylococcus aureus (19.7%) were the most prevalent isolates in admission cultures. During the next weeks, these bacteria were superceded by mainly Pseudomonas aeruginosa. Between admission and 21st day, the rates of methicillin resistance of staphylococci strains increased steadily. There was no vancomycin resistance in any staphylococci strains, although nine of the S. aureus isolates (2.7%) were resistant to teicoplanin. There were no strains producing inducible beta lactamase (IBL) among P. aeruginosa strains. One extended-spectrum beta-lactamase (ESBL)-producing strain was recovered on admission, although strains producing IBL and ESBL were detected at rates of 79.6 and 57.1%, respectively, on the 21st day. The nature of microbial wound colonization, flora changes, and antimicrobial sensitivity profiles should be taken into consideration in using empirical antimicrobial therapy of burned patients.

[Correlation of urinary tract infections with the vaginal colonization in postmenopausal women].

Estrogen deficiency is a major contributor to the pathogenesis of urinary tract infections (UTI) in postmenopausal women. After menopause, the vaginal pH increases, lactobacilli disappear from the vaginal flora, and the vagina is predominantly colonized by Enterobacteriaceae, especially Escherichia coli. To better understand the associations between post-menopausal vaginal flora and the development of UTI, we conducted a prospective study among 87 postmenopausal women ages between 50-65 years. Vaginal samples were collected from lateral vaginal wall of women to perform a smear on a glass slide and placed on appropriate media. The smear was then stained with Gram stain. Urine samples were collected and cultured by standard bacteriologic techniques. Vaginal lactobacilli were present in 55.2%, and vaginal Enterobacteriaceae were present in 40.2% of the subjects. Heavy growth of lactobacilli was associated with a lower frequency of vaginal colonization with Enterobacteriaceae members (p<0.001), Streptococcus sp. (p<0.05) and Pseudomonas sp. (p<0.05). The most commonly isolated microorganism was E. coli. The frequency of asymptomatic bacteriuria and symptomatic UTI among postmenopausal women were found 17.5% (15/87) and 11.5% (10/87), respectively. As a result, Enterobacteriaceae colonization of the vagina in postmenopausal women increases the prevalence of asymptomatic bacteriuria and symptomatic UTI (p<0.01 and p<0.05, respectively).

Anthrax during pregnancy: case reports and review.

We review, in detail, 2 cases of anthrax during pregnancy, its maternal and perinatal complications, and its management. Patient 1 was a 33-year-old woman at 32 weeks of gestation. She had a submandibular eschar; extensive edema on her face, neck, and upper thorax that inhibited respiratory function; and fever. The patient was treated with penicillin G and prednisolone after the diagnosis of anthrax. She recovered within 10 days but delivered a preterm baby. Patient 2 was a 29-year-old woman at 33 weeks of gestation. Her anthrax lesion was on her right elbow, and therapy consisted of procaine penicillin. She also delivered a preterm baby. These 2 cases show that anthrax during pregnancy can be successfully managed, but preterm delivery could be a complication.

[Role of the surgeon in the hospital infections control committees].

Hospital-acquired infections are the ones that develop within hospital stay or appear after discharge. These infections are associated with an increased rate of morbidity and mortality, longer hospital stay and higher hospital costs and Hospital Infections Control Committees have been founded to prevent it. In this review, we intended to investigate the role of the surgeon in this committee.

[Nasal carriage of Staphylococcus aureus in hospital personnel and the normal population and antibiotic resistance of the isolates].

Nasal carriage of Staphylococcus aureus plays a key role in the epidemiology and pathogenesis of infection, and is a major risk factor for the development of both community-acquired and nosocomial infections. The objective of this study was to investigate the carriage rate of S. aureus in hospital personnel and normal population groups, and to compare the resistance rates of the isolated strains to certain antibiotics. The nasal carriage rates of S.aureus were found to be 27.5% in 262 hospital personnel, and 24.0% in 75 normal healthy subjects (p > 0.05). While methicillin resistant S. aureus rate was 9.7% in hospital personnel, no methicillin resistant strain was detected in the control group (p < 0.05). According to the in-vitro sensitivity test results, resistance rates of meticillin sensitive S. aureus (MSSA) strains isolated from hospital personnel to fusidic acid, erythromycin and clindamycin were as 11%, 18% and 12%, respectively. There were no resistant strains to these antibiotics among MSSA, isolated from normal subjects. In conclusion, the colonization of the resistant strains rather than the frequency of S. aureus colonization is more important in the hospital personnel.
