Frequency of fibromyalgianess in patients with rheumatoid arthritis and ankylosing spondylitis: A multicenter study of Turkish League Against Rheumatism (TLAR) network.

Objectives: This study aimed to evaluate the frequency of fibromyalgianess, fibromyalgia syndrome (FS), and widespread pain in patients with rheumatoid arthritis (RA) and ankylosing spondylitis (AS) and their relationship with clinical and demographic parameters. Patients and methods: This cross-sectional multicenter trial was performed in 14 centers across Türkiye between June 2018 and November 2019. Out of 685 patients recruited from the accessible population, 661 patients (342 RA, 319 AS; 264 males, 397 females; mean age: 48.1±12.9 years; range, 17 to 88 years) met the selection criteria. In these cohorts, those who did not meet the criteria for FS and had widespread pain (widespread pain index ≥7) were evaluated as a separate group. Clinical status and demographic parameters of patients in both cohorts were evaluated as well as the evaluations of RA and AS patients with widespread pain (widespread pain index ≥7) and RA and AS patients with FS groups. In addition, correlations between polysymptomatic distress scale (PSD) scores and Visual Analog Scale (VAS), Simplified Disease Activity Index (SDAI), Clinical Disease Activity Index (CDAI), and Disease Activity Score using 28 joint counts for RA patients and VAS, Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), and Ankylosing Spondylitis Disease Activity Score (ASDAS) for AS patients were analyzed. Results: Frequencies of patients with FS and patients who had PSD scores ≥12 were 34.1% and 44.4% in all RA patients, respectively. Moreover, FS and PSD scores ≥12 were found in 29.2% and 36.9% of all AS patients, respectively. PSD scores of RA patients with FS were higher than all RA patients and RA patients with widespread pain. SDAI and CDAI scores of RA patients with FS were higher than all RA patients and RA patients with widespread pain. Similarly, PSD scores of AS patients with FS were higher than all AS patients and AS patients with widespread pain. ASDAS-erythrocyte sedimentation rate and BASDAI scores of AS patients with FS were found higher than all AS patients and AS patients with widespread pain. Conclusion: Disease activity scores, including pain in RA and AS, were higher in the presence of FS or fibromyalgianess. It may be related to clinical parameters, but cohort studies with long-term follow-up are needed to reveal causality. Additionally, to avoid overtreatment, coexistence of fibromyalgianess should be kept in mind in patients who have inflammatory diseases such as RA and AS, particularly with intractable widespread pain.

Development of the extraocular muscles during the fetal period.

PURPOSE: The aim of this study was to investigate the morphometric development of the extraocular muscles in the fetal period and to create a modified Tillaux spiral. METHODS: We dissected 157 fetal eyes (82 right eyes, 75 left eyes) obtained from 79 fetuses (46 boys, 33 girls) between 13 and 40 weeks of gestation. The tendon widths of the extraocular muscles and the distances of the tendon attachment sites to the limbus were measured. Tillaux's modified spiral was created. RESULTS: In addition to the rectus muscles, we added tendon widths and tendon-limbus distances of the upper (SO) and lower (IO) obliques to the modified Tillaux spiral. When tendon widths were compared between genders, no statistically significant difference was observed. When tendon widths were compared between the sides, it was determined that SO was more in the left eye, whereas other extraocular muscles were more in the right eye. There was no statistically significant difference between genders when the distances of tendon attachment sites to the limbus were compared. There was no statistically significant difference in SO and IO values between the sides. There was a statistically significant difference in the rectus muscles and this difference was found to be higher in the right eye. CONCLUSION: We think that the findings obtained will contribute to disciplines such as fetopathology, obstetrics, ophthalmology and plastic surgery and to future studies on this subject.

Prophylactic complex physiotherapy in gynecologic cancer survivors: patient-reported outcomes based on a lymphedema questionnaire.

OBJECTIVE: Lower extremity lymphedema secondary to cancer treatment impacts quality of life for gynecological cancer survivors. Complex decongestive physiotherapy is applied when lymphedema is diagnosed, but prophylactic physiotherapy is not yet a standard of care. The aim of this study is to evaluate prophylactic complex physiotherapy in patients with gynecological cancer and its effects on patient-reported symptoms based on the Gynecologic Cancer Lymphedema Questionnaire. METHODS: The data of patients diagnosed with gynecological cancers who underwent lymphadenectomy from July 2021 to June 2022 was evaluated. All patients were referred to the physiotherapy unit before adjuvant treatment. Patients who accepted prophylactic physiotherapy were informed and massage and exercise training were implemented, whereas patients who declined were solely informed. Bilateral lower extremity circumferences were measured at 1, 3, 6, and 12 months at the levels of 10 cm, 30 cm, and 50 cm above the heels. A translated form of the Gynecologic Cancer Lymphedema Questionnaire was administered to all patients at the last visit. RESULTS: A total of 100 patients were included in the study. Patients were diagnosed with endometrial (50%), ovarian (32%), cervical (16%), and vulvar (2%) cancer. Overall, 70% underwent systematic pelvic±para-aortic lymphadenectomy whereas sentinel lymph node mapping was performed in 30%. Lymphedema was seen in 5% (n=3) of the prophylactic physiotherapy positive group and in 60% (n=24) of the physiotherapy negative group. The median score was 3 (range 1-5) in the physiotherapy positive group and 16 (range 9-20) in the physiotherapy negative group. In patients diagnosed with lymphedema in the physiotherapy negative group, systematic lymphadenectomy was performed in 91.7% (n=22) and a higher number of lymph nodes was extracted (median 45.5; p=0.002). CONCLUSION: Prophylactic complex physiotherapy is associated with lower rates of lymphedema and better patient-reported symptom scores according to the Gynecologic Cancer Lymphedema Questionnaire.

SARcopenia Assessment in Hypertension: The SARAH Study.

OBJECTIVES: The aims of the study were to investigate the relationship between sarcopenia and renin-angiotensin system-related disorders and to explore the effects of angiotensin-converting enzyme inhibitors and angiotensin II receptor blockers on muscle mass/function and physical performance. DESIGN: This multicenter, cross-sectional study was performed using ISarcoPRM algorithm for the diagnosis of sarcopenia. RESULTS: Of the 2613 participants (mean age = 61.0 ± 9.5 yrs), 1775 (67.9%) were hypertensive. All sarcopenia-related parameters (except chair stand test in males) were worse in hypertensive group than in normotensive group (all P < 0.05). When clinical/potential confounders were adjusted, hypertension was found to be an independent predictor of sarcopenia in males (odds ratio = 2.403 [95% confidence interval = 1.514-3.813]) and females (odds ratio = 1.906 [95% confidence interval = 1.328-2.734], both P < 0.001). After adjusting for confounding factors, we found that all sarcopenia-related parameters (except grip strength and chair stand test in males) were independently/negatively related to hypertension (all P < 0.05). In females, angiotensin-converting enzyme inhibitors users had higher grip strength and chair stand test performance values but had lower anterior thigh muscle thickness and gait speed values, as compared with those using angiotensin II receptor blockers (all P < 0.05). CONCLUSIONS: Hypertension was associated with increased risk of sarcopenia at least 2 times. Among antihypertensives, while angiotensin-converting enzyme inhibitors had higher muscle function values, angiotensin II receptor blockers had higher muscle mass and physical performance values only in females.

The relationship between sarcopenia-related measurements and osteoporosis: The SARCOP study.

As muscle and bone are closely-related, we have explored the association between sarcopenia-related measurements and bone mineral density (BMD) (and osteoporosis) in postmenopausal women. Grip strength, anterior thigh muscle thickness and chair stand test were found to be related with BMD. Additionally, grip strength < 22 kg increased the odds ratio of osteoporosis 1.6 times. INTRODUCTION: As muscle and bone are two closely related tissues, we aimed to investigate the association between sarcopenia-related measurements (i.e., sonographic anterior thigh muscle thickness, grip strength, chair stand test (CST), gait speed) and clinical factors, lumbar/femoral BMD, and the presence of osteoporosis (OP) in postmenopausal women. METHODS: Community dwelling postmenopausal women from two physical and rehabilitation medicine outpatient clinics were consecutively included in this cross-sectional study. Demographic data, age, weight, height, education/exercise status, smoking, and comorbidities were registered. BMD measurements were performed from lumbar vertebrae (L1-4) and femoral neck using dual energy X-ray absorptiometry (DXA). A T-score of ≤ -2.5 SD in the lumbar vertebrae (L1-L4) and/or femoral neck was accepted as OP. Anterior thigh muscle thickness (MT) at the midthigh level was measured sonographically using a linear probe. Grip strength was measured from the dominant side. Physical performance was assessed by CST and gait speed. RESULTS: Among 546 postmenopausal women, 222 (40.7%) had OP. Among sarcopenia-related parameters, grip strength and anterior thigh MT were positively associated with lumbar vertebral BMD. CST performance was positively associated with femoral neck BMD. After adjusting for confounding factors, low grip strength (< 22 kg) increased 1.6 times the risk of OP. CONCLUSION: Loss of muscle mass/function (i.e., sarcopenia) can coexist with loss of trabecular and cortical bone. To this end, grip strength and anterior thigh MT seem to be associated with the lumbar vertebral BMD, while CST is associated with the femoral neck BMD. Lastly, low grip strength might have an association with postmenopausal OP.

The Comparative Frequency of Breast Cancer-Related Lymphedema Determined by Bioimpedance Spectroscopy and Circumferential Measurements.

Objective: The survival of patients with breast cancer has prolonged due to early diagnosis and modern methods of treatment and lymphedema has become the most important morbidity secondary to the treatment of the disease. Early detection and timely intervention have potential to reduce advanced breast cancer-related lymphedema. The aims of this study were to comparatively determine the frequency of subclinical/clinical lymphedema by using prospective monitoring with bioimpedance spectroscopy (BIS) and circumferential measurements in a group of patients who underwent breast cancer surgery. Materials and Methods: Patients having breast cancer surgery were recruited between October 2018 and December 2019. Demographical and surgical properties were recorded. Extremity volumes by circumferential and BIS measurements were performed after surgery (baseline) and monitorizations were carried out at third and sixth months, in order to determine the frequency of subclinical/clinical lymphedema. L-Dex value of >6.5 was recently taken attention as subclinical lymphedema and values >7 were considered as clinical lymphedema. The presence of subclinical and clinic lymphedema was assessed by inter-limb volume difference (>5% and >10 respectively) based on the serial circumferential measurements in both affected and non-affected extremities. The functional status and quality of Life (QoL) were determined by quick-DASH and LYMQOL-Arm questionnaires respectively. The relationship between volume measurements, functional status and QoL scores were determined. Results: Eighty-two female patients with a mean age of 49.6 years were included to the study. 30 (36.5%) and 21 (25.6%) of patients were determined as having subclinical/clinical lymphedema by BIS, while 18 (21.9%) and 19 (23.1%) of patients had subclinical/clinical lymphedema by circumferentialmeasurements at third-and-sixth months respectively. The functional and QoL scores were not correlated with circumferential volume measurements and BIS scores. There was a moderate-high correlation with BIS and circumferential measurements. Conclusion: In conclusion 36.5% and 25.6% of our study group had subclinical and clinical lymphedema by BIS respectively during the 6 months surveillance period. Periodic monitoring of women with BIS allows early detection for lymphedema in more patients than in circumferential volume measurements, which may have implications for timely and necessary management.

The Comparative Efficacy of Conventional Short-Stretch Multilayer Bandages and Velcro Adjustable Compression Wraps in Active Treatment Phase of Patients with Lower Limb Lymphedema.

Background: Compression is the most important component of complete decongestive therapy (CDT), but there is no standard best method for applying compression. The aim of this study was to evaluate the comparative efficacy of conventional multilayer short-stretch bandaging, and a velcro adjustable compression wrap with regard to volume reduction, ultrasonographic measurements, functional-status, and quality of life (QoL) in the active CDT period of patients with lower limb lymphedema. Methods and Results: The demographic and clinical variables of lower limb lymphedema patients were recorded. All patients received skin care education, manual lymphatic drainage, and supervised lyphedema exercises, and were randomly allocated to Group1 (multilayer short-stretch bandaging-Rosidal-K®) or to Group 2 (adjustable-compression-velcro-wrap-Circaid Reduction-kit®) for a duration of 3 weeks with 15 sessions. Limb volumes were assessed by perometer. Ultrasonographic measurements included subcutaneous soft tissue thickness. The functional disability and QoL were evaluated by the Lower Extremity Functional Scale and LYMQOL-Leg (Lymphedema Quality of Life Questionnaire-Leg), respectively, at baseline, after CDT, and at first-month follow-up. Thirty-six patients (10 male and 26 female) with mean age of 51.6 ± 11.7 years were included. Fourteen patients had primary and 22 patients had secondary lymphedema. The median duration of lymphedema was 68 months. Significant improvements in volumes and ultrasonographic measurments were observed in both groups at the end of therapies, and improvements sustained up to a month. Appearance, symptoms, and overall QoL-subscores were improved only in Group 2. Conclusion: In conclusion, adjustable compression velcro-wrap performed as a part of CDT can greatly reduce the volume similiar to conventional multilayer bandages, as well as improve the QoL. It can be a comfortable alternative to the conventional multilayer bandages in the active treatment phase of the CDT.

Reassessing Sarcopenia in Hypertension: STAR and ACE Inhibitors Excel.

BACKGROUND: Hypertension and sarcopenia are commonly seen in older adults. The renin-angiotensin system and the therapeutic use of angiotensin-converting enzyme (ACE) inhibitors have been on the agenda of sarcopenia in different perspectives. Our aim was to explore the frequency of sarcopenia in patients with hypertension and to investigate the association between the use of ACE inhibitors and sarcopenia. METHODS: A total of 272 community-dwelling adults were recruited. Anterior thigh muscle thickness was measured by ultrasound. Handgrip strength, gait speed, and chair stand test were evaluated. Low muscle mass was diagnosed in the presence of low sonographic thigh adjustment ratio (STAR) values and sarcopenia was diagnosed if low STAR values were coupled with low functional tests. RESULTS: 136 subjects (50.0%) had no comorbid disease; 102 (37.5%) had one, 21 (7.7%) had two, nine (3.3%) had three and four (1.5%) had four comorbid diseases. Both low muscle mass (41.9% vs 13.2%) and sarcopenia (32.2% vs 7.8%) were more commonly seen in hypertensive when compared with normotensive older adults. Subgroup analysis of older adults with hypertension revealed that sarcopenia was less prevalent (P = .003) in patients using ACE inhibitors (8.7%) than those using angiotensin II receptor blockers (48.7%) and other antihypertensive drugs (46.4%). After binary logistic regression analyses; only the presence of hypertension seemed to independently predict the development of sarcopenia in older adults [OR = 6.5 (95% CI: 2.4-17.8, P < .001)]. CONCLUSIONS: Sarcopenia is highly prevalent in hypertensive older adults. Amongst many antihypertensive medications, ACE inhibitors seem to have favourable effects on both disorders.

The Morphological Anatomy of the Menisci of the Knee Joint in Human Fetuses.

BACKGROUND: Development of the foetal period of the meniscus has been reported in different studies. AIMS: Evaluation of lateral and medial meniscus development, typing and the relationship of the tibia during the foetal period. STUDY DESIGN: Anatomical dissection. METHODS: We evaluated 210 knee menisci obtained from 105 human foetuses ranging in age from 9 to 40 weeks' gestation. Foetuses were divided into four groups, and the intra-articular structure was exposed. We subsequently acquired images (Samsung WB 100 26X Optical Zoom Wide, Beijing, China) of the intra-articular structures with the aid of a millimetric ruler. The images were digitized for morphometric analyses and analysed by using Netcad 5.1 Software (Ak Mühendislik, Ankara, Turkey). RESULTS: The lateral and medial meniscal areas as well as the lateral and the medial articular surface areas of the tibia increased throughout gestation. We found that the medial articular surface areas were larger than the lateral articular surface areas, and the difference was statistically significant. The ratios of the mean lateral and medial meniscal areas to the lateral and medial articular surface areas, respectively, of the tibia decreased gradually from the first trimester to full term. The most common shape of the medial meniscus was crescentic (50%), and that of the lateral meniscus was C-shaped (61%). CONCLUSION: This study reveals the development of morphological changes and morphometric measurements of the menisci.

Appearance of external genital organs and types of hymen in Turkish female foetal cadavers.

The present study's purpose was to determine the size and morphometric development of the female external genital organs on foetal cadavers. Dimensions of labia majora, labia minora and clitoris, bilabial diameter, vertical and horizontal diameters of hymenal opening, distance between the external urethral orifice and hymenal opening, distance between the clitoris and external urethral orifice and anogenital distance were measured. The hymenal types were determined. Mean values of parameters according to gestational weeks, months and trimesters were calculated. Imperforate hymen were determined in the first trimester. Twenty-eight foetuses with annular hymen, 25 foetuses with imperforate hymen, and 1 foetus with septated hymen were determined in the second trimester. Twenty-four foetuses with annular hymen, 3 foetuses with imperforate hymen, 1 foetus with fimbriated hymen, and 1 foetus with hymenal tag were determined in the third trimester. All foetuses in the full term were determined with annular hymen.

Location of facial foramina and mandibular angle from cone beam computed tomographic scans.

PURPOSE: The current study's purpose was to determine morphometric analysis of all facial foramina and mandibular angle relative to surgical landmarks from cone beam computed tomographic scans. MATERIALS AND METHODS: Three-dimensional computed tomographic scans were reconstructed from data of 100 patients (200 sides) aged between 19 and 76 years. Morphometric measurements of all facial foramina relative to surgical landmarks were taken. Mandibular angle was measured. RESULTS: There was no statistically significant difference between the left and right sides for all parameters (P > 0.05). Therefore, we found bilateral symmetry in the position of all facial foramina and mandibular angle. However, statistically significant differences were determined in sexes in some of these parameters and mandibular angle. CONCLUSIONS: The knowledge about locations of facial foramina and mandibular angle is important for performing local nerve block and surgery in the face to avoid the neurovascular structures. This study provides a guideline for locations of facial foramina and mandibular angle, which may help surgeons to understand the nerve location precisely during surgery.

A morphometric study of suprarenal gland development in the fetal period.

PURPOSE: The present study's purpose was to examine the morphometric development of the suprarenal gland using anatomic dissection methods during the fetal period. METHODS: This study was performed on 172 human fetuses (76 males and 96 females) and 344 fetal suprarenal glands obtained from ages 9-40 weeks of gestation with no external pathology or anomaly. Fetuses were divided into 4 groups between gestational ages as follows: Group 1, 9-12 weeks (first trimester); Group 2, 13-25 weeks (second trimester); Group 3, 26-37 weeks (third trimester); and Group 4, 38-40 weeks (full term). Also, the fetuses were grouped into monthly cohorts: 9-12 weeks 3rd month, 13-16 weeks 4th month, 17-20 weeks 5th month, 21-24 weeks 6th month, 25-28 weeks 7th month, 29-32 weeks 8th month, 33-36 weeks 9th month, and 37-40 weeks 10th month. The suprarenal glands were dissected in the abdominal cavity. The dimensions (width, length, and thickness), volumes and weights of the suprarenal glands were evaluated. The ratio of the fetal suprarenal gland weight/fetal body weight, the ratio of the fetal suprarenal gland volume/fetal kidney volume, and the ratio of the fetal suprarenal gland dimensions/fetal kidney dimensions were evaluated. RESULTS: Mean values and standard deviations of all parameters according to gestational weeks and trimesters were calculated. It is found that all parameters increase with gestational age. There was significant correlation between gestational age and all parameters (p < 0.001). No significant differences were observed between sexes for any of the parameters (p > 0.05). There was no difference between the right and left sides of parameters except the thickness of the suprarenal glands. The left suprarenal glands were thicker than the right. The ratio of suprarenal volumes to kidney volumes was determined, and we observed that the ratio decreased during the fetal period. CONCLUSIONS: We believe that the results obtained from this study will be beneficial in understanding the development of suprarenal glands and also contribute to future studies in obstetrics, perinatology, and fetopathology.

The morphometry of patella and patellar ligament during the fetal period.

This study aims to determine the development and morphology of the patella and patellar tendon and to obtain morphometric data about these structures during the fetal period. One hundred five human fetuses (55 males and 50 females) aged 9-40 weeks were used in this study. Fetuses were divided into four groups between gestational weeks; Group I (9-12 weeks), Group II (13-25 weeks), Group III (26-37 weeks), and Group IV (38-40 weeks). The patella and patellar ligament were exposed via anatomical dissection; the dimensions (length, width, thickness) and the width of the lateral and medial articular surfaces of the patella, and the length and width of the patellar ligament, were measured using a Vernier's caliper. No significant differences were observed between genders or sides for any of the parameters (P > 0.05), and a significant correlation was found between gestational age and all parameters (P < 0.001). All parameters of the patella and patellar ligament were found to be different statistically between trimesters (P < 0.05). This study reveals the development, morphological changes, and the morphometric measurements of the patella and patellar ligament during the fetal period. We hope that the present results can be useful for future studies.

Modeling the economic impact of pandemic influenza: a case study in Turkey.

Influenza pandemics have occurred intermittently throughout the 20th century and killed millions of people worldwide. It is expected that influenza pandemics will continue to occur in the near future. Huge number of deaths and cases is the most troublesome aspect of the influenza pandemics, but the other important trouble is the economic impact of the influenza pandemics to the countries. In this study, we try to detect the cost of a possible influenza pandemic under different scenarios and attack rates. We include the vaccination and antiviral treatment cost for direct cost and we add the work absenteeism cost to the calculations for indirect cost of influenza pandemics. As a case study, we calculate the economic impact of pandemic influenza for Turkey under three different scenarios and three different attack rates. Our optimistic estimation shows that the economic impact of pandemic influenza will be between 1.364 billion dollars and 2.687 billions dollars to Turkish economy depending on the vaccination strategies.

Morphometry of the gallbladder during the fetal period.

PURPOSE: In this study, our objective was to investigate the development of the gallbladder, its morphological structure and relationship with the adjacent organs during the fetal period. MATERIALS AND METHODS: A total of 118 human fetuses (60 males, 58 females) between 9 and 40 weeks of gestation without any external anomaly or pathology were included. They were divided into four groups according the gestational age: I (9-12 weeks), II (13-25 weeks), III (26-37 weeks) and IV (term, 38-40 weeks). The location of gallbladder on the visceral surface of liver has been identified. The gallbladders have been classified into four different types. Width and length of the gallbladder were measured and the relationship between fundus of gallbladder and inferior margin of the liver was noted. FINDINGS: The gallbladder was located on the visceral surface of liver in all cases during the fetal period. There were no differences between males and females by means of length and width. There was a statistically significant relationship between the size of gallbladder and the gestational age (P < 0.001). There was also a significant difference in the distribution of gallbladder types among the groups during the fetal period. The fundus of gallbladder was under the transverse plane passing from the part of inferior margin of the liver near the gallbladder in 14% of the cases. RESULTS: We concluded that there could be different types of gallbladders during the fetal period. We believe that the data collected in our study may contribute to the evaluation of the gallbladder development during the intrauterine period.

A simulation approach for scheduling patients in the department of radiation oncology.

Physical therapy, hemodialysis and radiation oncology departments in which patients go through lengthy and periodic treatments need to utilize their limited and expensive equipment and human resources efficiently. In such departments, it is an important task to continue to treat current patients without any interruption along with incoming patients. In this study, a patient scheduling approach for a university radiation oncology department is introduced to minimize delays in treatments due to potential prolongations in treatments of current patients and to maintain efficient use of the daily treatment capacity. A simulation analysis of the scheduling approach is also conducted to assess its efficiency under different environmental conditions and to determine appropriate scheduling policy parameter values. Also, the simulation analysis of the suggested scheduling approach enables to determine appropriate scheduling parameters under given circumstances. Therefore, the system can perform more efficiently.

[Molecular characteristics of methicillin-resistant Staphylococcus aureus strains isolated from blood cultures between 2002-2005 in Ankara University Hospital]. / Ankara Universitesi Hastanesinde 2002-2005 yillari arasinda kan kültürlerinden izole edilen metisiline dirençli Staphylococcus aureus suslarinin moleküler ozellikleri.

This study was conducted to investigate the antimicrobial susceptibility, Panton Valentine leucocidine (PVL) and toxin (enterotoxin A-J, staphylococcal toxic shock toxin) genes, agr types, staphylococcal cassette chromosome mec (SCCmec) types and pulsed field gel electrophoresis (PFGE) profiles of a total of 100 non-duplicate methicillin-resistant Staphylococcus aureus (MRSA) bloodstream isolates collected between 2002-2005 at Ankara University Ibn-i Sina Hospital. Antimicrobial susceptibilities were investigated by a semi-automated system (miniAPI, BioMerieux, France); PVL, mecA and toxin (sea, seb, sec, sed, see, seg, seh, sei, sej, tst) genes by polymerase chain reaction (PCR) and SCCmec and agr typing were performed by multiplex PCR. While all isolates were susceptible to vancomycine, aminoglycoside and tetracycline resistance was determined in 91%, ciprofloxacine in 93%, rifampin in 92%, erythromycine in 79% and trimethoprim-sulphametoxazole in 8% of the isolates. mecA gene was detected in all of the isolates, however, PVL positive isolate was not detected. sea was the most frequently (77%) detected enterotoxin gene. SCCmec typing revealed type III in 84 (84%) and agr typing revealed type I in 91 (91%) of the isolates. Multilocus Sequence Typing (MLST) of five representative isolates (two isolates with pattern A, one isolate each from patterns B, C and D) revealed sequence type (ST) 239. This study documented that the dominant MRSA clone in our hospital had SCCmec type III, agr type 1, PVL negative, sea positive and of ST 239. Larger scale intercity and nation wide studies are needed to find out the clonal characteristics of hospital acquired MRSA in Turkey.

The development of fetal pylorus during the fetal period.

OBJECTIVE: The objective of this study was to explore the localization of the pylorus, its macroscopic and microscopic development and relationship with neighboring structures. MATERIALS AND METHODS: The study is carried out on 160 human fetuses aged between 9 and 40 weeks of gestation. Abdomen was divided into four quadrants by horizontal and vertical planes passing through the umbilicus. Topographical localization of the pylorus in reference to these quadrants and its distance were determined. Pylorus was divided into pre-pyloric, pyloric, and post-pyloric regions. Starting from the pre-pyloric end, serial sections spanning whole pyloric part were obtained. Wall thickness, the thickness of the muscular coat were measured under light microscope using sections stained with hematoxylin eosin. Sections with the thickest muscular coat were considered as the region where pyloric sphincter was. FINDINGS: Pylorus was located in the right upper quadrant, on the median plane and in the left upper quadrant. There was a significant relation between the thickness of the muscular coat in the stomach, duodenum and the pyloric region and gestational age. In the region of the pyloric sphincter, the rate of increase in the thickness of the muscular coat was higher in the first and the first half of the second trimesters than term fetuses. CONCLUSION: We believe that data obtained in the present study will contribute to the assessment of development of the pyloric region in intra-uterine cases.
