Morbidity, fertility and pregnancy outcomes after myoma enucleation by laparoscopy versus laparotomy.

OBJECTIVES: Myomas are defined as benign tumours that arise from smooth muscle cells of the uterus. Clinically, they are found in 5-77% of women of reproductive age. The prevalence rate varies considerably in the literature and a large number of fibroids do not cause symptoms. The lifetime risk of acquiring myomas is 70% for Caucasian women and ≥ 80% for African American women. MATERIALS/METHODS: The data of 265 patients undergoing surgery for symptomatic myomas by laparoscopy or laparotomy, performed in the gynaecological department of Hannover Medical School, Hannover, Germany, between 2009 and 2013, were retrospectively analysed in this retrospective design study. RESULTS: High pregnancy rates (up to 70%) and birth rates (up to 86%) after myomectomy, regardless of the surgical approach adopted, were found in the current study. The trend was that ≥ 3 myomas and those that were ≥ 6 cm in size were almost always removed by laparotomy in our clinic. It was possible to remove up to 42 myomas without having to perform a hysterectomy. A statistically significant negative correlation was observed in relation to the association between the size of the largest myoma extracted and the pregnancy rate (p = 0.02). A statistically significant correlation between the number of removed myomas and the pregnancy rate was observed for patients who wished to bear children (p = 0.010). Elevated complication rates (of up to 50%) were reported for more than three extracted myomas with a statistically significance (p = 0.0471). CONCLUSIONS: It is necessary to ensure sound preoperative selection of the surgical approach in order to achieve the most optimal results, especially for those patients who wished to bear children.

Direct comparison of two vaginal self-sampling devices for the detection of human papillomavirus infections.

BACKGROUND AND OBJECTIVES: Two devices for vaginal self-sampling of dry cell material (Evalyn Brush, Rovers Medical Devices; Qvintip, Aprovix) were compared using the Abbott RealTime High Risk HPV test. STUDY DESIGN: Both self-sampling devices (change of order with every patient) including instructions for use and a questionnaire were handed to 146 patients in a colposcopy clinic prior to scheduled colposcopies with collection of cervical reference specimens by gynaecologists using a broom-like device. Matched self-collected and physician collected specimens were transferred to ThinPrep medium and tested for the presence of hr-HPV. Biopsies were taken if indicated by colposcopy. RESULTS: Evaluation of 136 patients with complete data (136/146; 93.2%) showed high agreement of overall hr-HPV detection rates between self-collected and clinician-collected specimens (Evalyn: 91.2% [kappa 0.822]; Qvintip: 89.0% [kappa 0.779]). Colposcopy and histological evaluation revealed 55 women without cervical intraepithelial neoplasia (CIN), 32 CIN1, 34 CIN2, 14 CIN3 and one adenocarcinoma in situ. Hr-HPV testing detected all CIN3+ cases on the clinician-taken or Evalyn self-samples (14/14) and 93% of them on the Qvintip samples (13/14). There was no significant difference regarding the sensitivity for CIN2+ or CIN3+ and specificity of hr-HPV testing on self- vs. clinician samples and on Evalyn vs. Qvintip. Based on signal intensities of ß-globin, the observed DNA concentration with Evalyn samples (mean CN: 22.0; 95%-CI: 21.5-22.6) was found to be significantly higher compared to that of Qvintip samples (mean CN: 23.8; 95%-CI 23.2-24.4), regardless of the order of self-sampling (p<0.0001). Most women considered self-sampling easy and comfortable. Qvintip was considered easier than the Evalyn Brush to understand (p<0.001) and to use (p=0.002). DISCUSSION: This study confirms that hr-HPV testing with a clinically validated PCR-based HPV assay is as accurate on self-samples as on clinician-samples without significant difference between both self-sampling devices.

Accuracy of Colposcopically Guided Diagnostic Methods for the Detection of Cervical Intraepithelial Neoplasia.

Introduction: Many factors can affect the accuracy of colposcopically guided biopsy, endocervical curettage (ECC) and differential cytology, all of which are standard, minimally invasive procedures used to detect cervical intraepithelial neoplasia. Method: All conizations carried out between 2007 and 2013 in the gynecological department of Hannover Medical School were retrospectively reviewed. The agreement between colposcopic diagnosis and histology was evaluated retrospectively. The analysis included 593 complete datasets out of a total of 717 cases treated. Results: The overall agreement was 85.5 %; the accuracy was significantly higher (p = 0.029) when three biopsy specimens were taken rather than just one. The agreement between diagnosis and histological findings from conization was highest for women < 30 years (90.7 %) and lowest for women > 50 years (72.1 %; p = 0.008). The agreement between preoperative differential cytology and histology results after conization was 86.7 % and improved as patient age increased (p = 0.035). The agreement between ECC findings and the results of conization was only 49.1 % irrespective of patient age, transformation zone or the patient's menopausal status. Conclusion: The accuracy of colposcopically guided biopsy appears to increase when three biopsy specimens are taken and is particularly high for younger patients. Differential cytology was also found to be highly accurate and is particularly useful for patients aged more than 50 years. The accuracy of ECC was significantly lower; however ECC can provide important additional information in selected cases.

Background Knowledge and Attitude of Pregnant Women towards Ultrasound Screening at 20-23 Weeks Gestation.

BACKGROUND: Prenatal ultrasound screening in the second trimester is widely used in maternal health care. Prenatal diagnosis and prenatal screening is often exposed to several accusation, such as inducing unnecessary anxiety, carrying out a selection and forcing pregnant women into attending ultrasound screening. The aim of this study was to investigate the knowledge and the intention of pregnant women attending the second trimester ultrasound screening. PATIENTS AND METHODS: This was a prospective study. Women attending the 20 weeks anomaly scan were given an anonymous questionnaire to evaluate the background knowledge about the anomaly scan and their opinion about prenatal screening. RESULTS: 600 (96.7%) of 620 recruited women filled in the questionnaire completely. To the majority (>80%) of women it is important to exclude severe fetal anomalies and to secure normal fetal growth. The background knowledge of the women was good, but a clear supply of information and a detail counselling would improve the understanding, especially in the group of lower education. The majority of the women stated that the 20 weeks anomaly scan should be offered to every woman. CONCLUSION: Prenatal ultrasound examination is not only essential from a medical point of view for example for important information regarding the status of the fetus, but also has a major impact as a positive psychological factor for pregnant women.

Treatment of Giant Fibroadenoma in Young Women: Results after Tumor Excision without Reconstructive Surgery.

Introduction: Giant fibroadenoma (GFA) of the breast is defined as fibroadenoma larger than 5 cm, usually presenting unilaterally and manifesting as breast asymmetry or deformity of the breast. Material and Methods: A retrospective database search was done of all patients with giant fibroadenoma who underwent surgery for GFA in the breast center of Hanover Medical School between 2007 and 2014; all patients with GFA were followed up. Data were analyzed with regard to tumor and patient characteristics and esthetic outcome. Results: A total of 13 patients with symptomatic GFA underwent surgery between 2007 and 2014. Mean patient age was 21.2 years (range 14-31 years). In 8 of 13 patients the tumor had resulted in breast deformity and/or breast asymmetry. Average size of the mass was 10.2 cm (range 8.5-12 cm) and average weight was 203.6 g (range 151.2-323.5 g). Initial clinical suspicion of GFA was confirmed by ultrasound examination. Preoperative core biopsy revealed fibroadenoma in 8/13 cases, cellular fibroepithelial lesions with a differential diagnosis of benign phyllodes tumor in 3 cases and unspecific histological findings in the remaining 2 cases. Conclusion: Excision was done using an inframammary or periareolar approach without reconstructive plasty. The cosmetic results were good, as were the outcomes on follow-up. We therefore favor this surgical technique to treat giant fibroadenoma of similar size to those described above.

Increasing Liability Premiums in Obstetrics - Analysis, Effects and Options.

Whenever people act, mistakes are made. In Germany, it is thought that a total of 40 000 cases of malpractice occur per year. In recent years, costs for liability insurance have risen significantly in almost all spheres of medicine as a whole. Liability in the health care sector is founded on the contractual relationship between doctor and patient. Most recently, case law developed over many years has been codified with the Patients' Rights Act. In obstetrics, the focus of liability law is on brain damage caused by hypoxia or ischemia as a result of management errors during birth. The costs per claim are made up of various components together with different shares of damage costs (increased needs, in particular therapy costs and nursing fees, acquisition damage, treatment costs, compensation). In obstetrics in particular, recent focus has been on massively increased liability payments, also accompanied by higher liability premiums. This causes considerable financial burdens on hospitals as well as on midwives and attending physicians. The premiums are so high, especially for midwives and attending physicians, that professional practice becomes uneconomical in some cases. In recent years, these circumstances have also been intensely debated in the public sphere and in politics. However, the focus here is on the occupation of midwife. In 2014, in the GKV-FQWG (Statutory Health Insurance - Quality and Further Development Act), a subsidy towards the occupational liability premium was defined for midwives who only attended a few deliveries. However, to date, a complete solution to the problem has not been found. A birth will never be a fully controllable risk, but in rare cases will always end with injury to the child. The goal must be to minimise this risk, through good education and continuous training, as well as constant critical analysis of one's own activities. Furthermore, it seems sensible, especially in non-clinical Obstetrics, to look at the current study data more closely. Among the many solutions which have been proposed, such as the development of quality management, risk management and prevention, better remuneration, a waiver on recourse claims by social insurance underwriters, a cap on damage costs of liability insurers, state liability, an indemnity fund, a system change to Medical Treatment Risk Insurance, as well as a discussion on whether or not it makes sense to use non-clinical obstetrics for the prevention of a further increase in premiums, not one stands out as being especially convincing. On the contrary, a meaningful coordination of various concepts should follow. What seems sensible is a higher remuneration per birth, taking into account the liability premiums as well as, in the medium term, the establishment of a liability fund which, from a certain limit upwards, steps in as liable third party.

Attitude toward, acceptance of and knowledge about female sterilization as a method of contraception.

OBJECTIVE: Surgical sterilization via tubal ligation or the disconnection of the tubes is a method of permanent contraception. The aim of this study was to evaluate the attitude, acceptance and knowledge of women about female sterilization as a method of contraception in terms of the social and cultural backgrounds of those women. STUDY DESIGN: Prospective study based on an anonymous questionnaire that analyzed background knowledge, attitude, influence factors and motivation regarding sterilization, as well as the reasons for declining. The questionnaire also attempted to evaluate the effects on the self-esteem of the women, as well as the impact of religious dogma and the related beliefs. RESULTS: One thousand, eight hundred questionnaires were distributed, and 1247 women completed the questionnaire­a response rate of 69.3%. There were mainly positive attitudes toward sterilization as a contraceptive method. Cultural background, including religion and faith; the mother's experiences and point of view; knowledge; family planning and the actual life situation have an influence on the attitudes toward and acceptance of sterilization as a contraceptive method and on the final choice of a contraceptive method. CONCLUSION: Cultural background and present life situation have a great impact on the attitude toward and acceptance of sterilization as a method of contraception, thus influencing the final choice of a contraceptive method. Detailed counselling about this topic is essential and should be improved.

Lymphedema of the breast as a symptom of internal diseases or side effect of mTor inhibitors.

A common situation presented in any clinical facility is a woman with swelling and redness of the breast. Diagnosis upon suspicion is often mastitis or inflammatory breast cancer, which are popular and well-known diseases of the breast. However, there is one main differential diagnosis which has to be taken into consideration: lymphedema of the breast. Twenty patients with internal diseases presented in our Breast Care Unit over a 4-year period with breast-affecting lymphedema. The patients suffered from cardiac failure, nephrotic syndrome, liver failure, lymphadenopathy, and central vein occlusion. Additionally, we identified 5 patients with a history of organ transplantation and under immunosupressive medication with sirolimus or everolimus. These mTor inhibitors are known to have unwanted side effects such as unilateral or bilateral upper/lower extremity peripheral edema or facial/eyelid edema, but as we know, isolated lymphedema of the breast represents a previously unreported complication.

Characterisation of the learning curve of caesarean section.

INTRODUCTION: Caesarean section is one of the common operations in medicine. As almost all interventions, the quality of the operation depends on the training and skills of the surgeon. This study aims at characterising the learning curve of caesarean section. MATERIAL AND METHODS: All patients with a singleton pregnancy who underwent a caesarean section between 2000 and 2009 in our university hospital were identified. We analysed datasets from beginners (no experience at all) and experienced surgeons (>300 caesarean sections, consultant) comparing the parameter incision-suture time (I-S time), incision-delivery time (I-D time), maternal blood loss, umbilical artery pH (ua-pH), APGAR score after 1, 5 and 10 min, mean time in hospital and postoperative complications. In addition, the first 100 caesarean sections of each beginner surgeon were divided in groups of 10 (1-10, 11-20, etc.) and analysed using the above-mentioned parameters. The learning curves were calculated. RESULTS: 2,515 of 3,844 operations were carried out by 23 experienced surgeons versus 1,329 operations by 22 beginners. The I-S time and I-D time was significantly higher in the beginners group than in the experienced surgeon's group (45.9 vs. 41.3 min, p < 0.001). Furthermore, for the first ten caesarean sections, the mean I-S time (47.9 min, 95% CI 45.7-50.0 min vs. 31-40th caesarean section with 43.1 min, 95% CI 40.9-45.3 min, p < 0.0001) and I-D time (9.5 min, 95% CI 8.6-10.5 min vs. 71-80th caesarean section with 4.8 min, 95% CI 4.2-5.4 min, p < 0.0001) was significantly higher than of the subsequent datasets of ten operations, showing a typical learning curve. CONCLUSION: The learning curve for the total operation time and incision-delivery time reaches a flatter part after 10-15 caesarean sections. However, the learning process is highly individualised and difficult to predict, so that supervision and evaluation of the trainee by an experienced surgeon is important.

Importance of HPV Genotyping for the Screening, Therapy and Management of Cervical Neoplasias.

In the last decade, the detection of human papillomaviruses (HPV) has become increasingly important in cervical cancer screening and the treatment of cancer precursors. HPV screening is recommended for the further evaluation of abnormal Pap tests or during follow-up after treating precancerous lesions. Several randomised controlled studies have shown that screening for cervical cancer using HPV detection can be more effective than cytology alone. Genotyping of different high-risk HPV (hrHPV) types obtained from smear tests has not yet gained widespread acceptance in clinical practice. However, significant differences have been noted in the oncogenicity of hrHPV genotypes. HPV 16 is by far the most common and oncogenic genotype. Genotyping of hrHPV could be helpful for the risk stratification of HPV-positive women.

A mixture model of nuchal translucency thickness in screening for chromosomal defects: validation of a single operator dataset.

OBJECTIVE: (1) To validate the mixture model in a single operator dataset and (2) to compare the detection rates for fetal chromosomal defects obtained from the mixture model with those obtained from either the delta nuchal translucency (NT) or log multiple of the median (MoM) approach. METHODS: Database query, viable singletons [crown-rump length (CRL) 45-84 mm corresponding to 11-13(+6) weeks], December 1997 to November 2006, examined by Adam Gasiorek-Wiens, the statistical mixture model was applied. RESULTS: Seventy-four of 4171 were lost to follow-up (1.8%), 4097 singleton pregnancies included trisomy 21 (n = 34, 0.8%), trisomy 18 (n = 20, 0.5%), trisomy 13 (n = 8, 0.2%), Turner syndrome (n = 9, 0.2%) and other chromosomal abnormalities (n = 14, 0.3%). The main findings are that (1) the log-transformed NT measurements follow a mixture of two Gaussian distributions and (2) the criteria to apply either the delta-NT or log MoM models are not met. In the normal group, the majority of NT measurements were dependent on the CRL, a small group showed a median independent of the CRL. In the abnormal group it was the opposite. For a 5% false-positive rate (FPR), the trisomy 21 detection rate was 83%. CONCLUSIONS: The use of the mixture model in a single operator dataset produces results compatible with the original study. The mixture model has thus been validated.

Prenatal diagnosis of the Rhesus D fetal blood type on amniotic fluid in daily practice.

OBJECTIVE: To retrospectively examine the diagnostic accuracy of prenatal RhD blood type genotyping on amniotic fluid, using a combination of two polymerase chain reaction (PCR) methods in daily practice. METHODS: Amniotic fluid was obtained from women undergoing amniocentesis. Two PCR protocols were carried out in two different laboratories. We obtained the postnatal serological RhD status. In cases with differing prenatal and postnatal test results, we investigated the possible error source by different methods. Sensitivity, specificity and the predictive values were calculated. RESULTS: Prenatal RhD genotyping was applied in 1,640 cases, of which the postnatal serologic RhD status was obtained in 927. No discordance between both PCR methods occurred. In nine out of 927 cases differing results between PCR and serologic status were encountered. The sensitivity was 99.5%, the specificity 98.6%, and both positive and negative predictive values 99.1%. CONCLUSION: Prenatal diagnosis of the fetal RhD blood type with PCR from amniotic fluid is highly accurate in daily practice and associated with a minimal sensitivity of 99.5% and a minimal specificity of 98.6%.

Individualized growth charts for ultrasound measurements can significantly improve fetal monitoring.

OBJECTIVE: For monitoring pregnancies it is useful to reduce unnecessary examinations due to wrongfully assumed growth retardation in cases with a small fetal growth potential. It also makes sense to improve the detection of objectively retardated children in order to a disproportionately high growth potential. It was the aim of this study to modify the standard growth charts for ultrasound parameters according to parental influences to better display the individual growth potential. MATERIAL AND METHODS: In a prospective trial 1,390 ultrasound measurements of 174 completed pregnancies were observed. For all patients a standard questionnaire was conducted in which possible predictors for fetal growth were collected. Customizing the growth charts had been achieved by (1) calculating the general impact of parental factors on the ultrasound measurement values, (2) plotting the individual growth charts for each pregnancy and (3) analyzing the difference of every observed measurement from either unchanged normal values or customized growth charts. RESULTS: The obtained biparietal diameter measurements all in all are 291 mm closer to the individualized charts than to the unmodified charts. The total improvement of all thoracal diameter measurements was found to be 294 mm, the summarized advancement of all abdomen circumference values was 1,005 mm and the femur length measurements are 296 mm nearer to customized charts. All results were statistically significant. DISCUSSION: This is the first time the impact of several predictors on ultrasound growth charts had been analyzed. While other working groups have demonstrated the benefit of customizing the fetal weight and length, this concept had never been carried forward onto the growth charts for ultrasound values. The method to adjust the common mean values by so called 'modifiers' is derived from the mathematical concept of the sequential first-trimester screening for Down's syndrome. For customizing growth charts this approach seems to be useful as well. The feasability and the statistical benefit of customizing ultrasound growth charts has been demonstrated in this work. A larger study seems to be promising and should be performed. Further improvements could be obtained by using normal growth charts which were derived from the examined cohort.

Screening for trisomy 21 with maternal age, fetal nuchal translucency and maternal serum biochemistry at 11-14 weeks: a regional experience from Germany.

OBJECTIVE: To examine the efficacy of first trimester screening for trisomy 21 using a combination of maternal age, fetal nuchal translucency (NT), maternal serum free beta-human chorionic gonadotropin (free beta-hCG) and pregnancy-associated plasma protein A (PAPP-A) in a regional setting [maternity unit of the Women's University Hospital, Hannover Medical School (study center); two regional private centers for prenatal diagnosis and human genetics; laboratory for prenatal diagnosis and human genetics]. METHODS: Fetal NT, crown-rump length, maternal serum free beta-hCG and PAPP-A were measured at 11-14 weeks of gestation. Risk calculation was carried out using the FMF computer algorithm. The patients were informed and counseled about possible invasive test options if the risk was 1 in 300 or greater. Fetal outcome was obtained by questionnaires given to the patients or sent to their gynecologists. The detection and false-positive rates for the different screening strategies were calculated. RESULTS: Pregnancy outcome was obtained in 2,497 cases, of which 2,196 cases had completed first trimester screening with NT and maternal serum biochemistry and 301 additional cases had NT measurement only. The median age was 32.5 years. In our population 11 affected fetuses were found. The estimated risk for trisomy 21 was 1 in 300 or greater in 64, 82, 88 and 88% of affected fetuses using maternal age alone, in combination with nuchal translucency, with maternal serum biochemical markers or with both NT and biochemical markers for a false-positive rate of 28.2, 5.1, 15.3 and 4.0%. CONCLUSIONS: First trimester screening using maternal age, NT, free beta-hCG and PAPP-A is highly effective for the detection of trisomy 21 and is associated with a sensitivity of about 90% for 5% false-positive patients.

Variation of bronchoalveolar lymphocyte phenotypes with age in the physiologically normal human lung.

BACKGROUND: Changes in T lymphocyte subsets have been observed in various forms of pulmonary disease. However, bronchoalveolar lymphocyte subsets have not been well characterised for healthy individuals differing in age. A study was undertaken to investigate the bronchoalveolar lavage (BAL) and peripheral blood lymphocyte subsets in clinically normal volunteers of two different age groups (19-36 and 64-83 years). METHODS: Bronchoalveolar lavage was performed on all individuals in both age groups and peripheral venous blood was drawn just prior to BAL. Bronchoalveolar cell profiles were characterised by morphological criteria, and cell surface antigen expression of lymphocytes was determined by flow cytometry. RESULTS: A significant increase in total BAL lymphocytes was observed for the oldest group compared with the youngest age group. Mean lymphocyte subset (CD4+/CD8+) ratios were significantly increased in BAL fluid from the older group compared with the younger group (mean (SE) 7.6 (1.5) vs 1.9 (0.2); p<0.0001). The increase in the BAL CD4+/CD8+ T cell ratio was mostly due to an increase in relative numbers of CD4+ lymphocytes, and the BAL CD4/CD8 ratio was disproportionately increased compared with peripheral blood in the older group. Increased expression of HLA-DR and CD69 on CD4+ T lymphocytes was observed in the oldest age group. Relative numbers of natural killer (NK) cells did not vary with age, and gammadelta T cells and CD5+ B cells were present in very low numbers in both age groups. CONCLUSIONS: CD4+ T cells accumulate in air spaces of the lower respiratory tract with age in healthy adults and express increased amounts of HLA-DR and CD69 on their surfaces, suggesting a relative degree of CD4+ T lymphocyte activation for healthy older individuals who have normal lung function.

Unopposed neutrophil elastase in bronchoalveolar lavage from transplant recipients with cystic fibrosis.

Large numbers of neutrophils with unopposed neutrophil elastase (NE) proteolytic activity are found in lower respiratory tract secretions from most patients with advanced cystic fibrosis (CF). To determine whether antielastase defenses may be overwhelmed in epithelial lining fluid after lung transplantation, we measured NE activity (cleavage of the specific substrate, MeO-Suc-Ala-Ala-Pro-Val-pNA) in bronchoalveolar lavage fluids (BALF) obtained for surveillance or diagnostic purposes at various intervals (1 mo to 7 yr after transplantation) from 52 recipients who had undergone double or bilateral lung transplantation for end-stage CF. Unopposed NE activity was found in BALF from 14 recipients, most of whom also had >= 10(5) colony forming units (cfu) of Pseudomonas aeruginosa in BALF. Ten of the 14 recipients with unopposed NE in bronchoalveolar lavage (BAL) had developed obliterative bronchiolitis (OB), but only 8 of the 38 subjects without unopposed NE activity had OB (p = 0. 002; Fisher exact test). We conclude that antiprotease defenses in lower respiratory tract secretions of CF patients receiving lung allografts are sufficient in the majority of patients to prevent unopposed NE activity. However, the presence of unopposed NE activity in BAL from lung allografts of patients with CF is associated with progressive, irreversible OB and graft failure.

Neutrophils and low-grade inflammation in the seemingly normal aging human lung.

Lung function deteriorates with age and is associated with elastin loss, loss of elastic recoil and decline in diffusing capacity for carbon monoxide. To determine whether increased numbers of neutrophils can be found in the lower respiratory tract in healthy, clinically normal individuals who are more advanced in age, we performed bronchoalveolar lavage (BAL) on individuals in three discontinuous age groups (Group I, 19-36 years; Group II, 45-55 years; Group III, 64 83 years). We found that neutrophils were increased in many individuals in Group III compared to Group I. The neutrophil cell differential count was 1.44+/-0.18% (mean+/-S.E.M.) for Group I versus 3.88+/-0.81% for Group III (P < 0.01) and neutrophils x 10(3)/ml BAL fluid was 1.7+/-0.2 versus 7.2+/-1.7 for Group I versus Group III, respectively (P < 0.01). Similarly, interleukin-8 (IL-8) (8.5+/-1.7 vs 36.8+/-9.4 pg/ml, P < 0.01) and neutrophil elastase (NE) complexed to alpha1-antiprotease (1.2+/-0.1 vs 16.6+/-7.1 ng/ml, P < 0.02) were significantly elevated in the oldest versus youngest age group, although alpha1-antiprotease (582+/-86 vs 1178+/-148 ng/ml, P < 0.01) and elastase inhibitory capacity (EIC) (8.1+/-1.3 vs 17.7+/-1.9 micromol/ml, P < 0.01) were also significantly increased in the oldest age group. This cross-sectional investigation suggests that low-grade inflammation exists in the air spaces of many clinically normal, older individuals.
