Abstract
Polyunsaturated fatty acids (PUFAs) have received attention for their anti-inflammatory and antioxidant properties. Preclinical studies have investigated the efficacy of PUFAs in animal models of spinal cord injury (SCI) to determine if these properties can translate to neuroprotection and locomotor recovery. Findings from such studies have been promising, suggesting PUFAs as potential treatments against the neurological dysfunction induced by SCI. This systematic review and meta-analysis sought to investigate the efficacy of PUFAs for promoting locomotor recovery in animal models of SCI. PubMed, Web of Science and Embase (Ovid) were searched for relevant papers and those that examined the restorative effects of PUFAs on locomotor recovery in preclinical SCI models were included in our analysis. A random effects meta-analysis (restricted maximum likelihood estimator) was employed. A total of 28 studies were included and the results showed the claim that PUFAs have a beneficial therapeutic effect for promoting locomotor recovery (SMD = 1.037, 95% CI = 0.809-1.2644, p = <0.001) and cell survival (SMD = 1.101, 95% CI = 0.889-1.313, p = <0.001) in animal models of SCI. No significant differences for the secondary outcomes of neuropathic pain and lesion volume. Moderate asymmetry was observed in the funnel plots for locomotor recovery, cell survival and neuropathic pain measures, suggesting publication bias. Trim-and-fill analysis estimated 13, 3, 0 and 4 missing studies for locomotor recovery, cell survival, neuropathic pain, and lesion volume, respectively. A modified CAMARADES checklist was also used to assess risk of bias, showing that the median score for all included papers was 4 out of a possible 7.

Abstract
BACKGROUND The intrauterine device (IUD), being a reversible and effective contraception method, is the most widely used worldwide. This study aims to demonstrate the efficacy of IUD insertion during elective lower segment cesarean section (LSCS) versus its insertion six weeks postpartum. METHODS A cohort study was conducted on 200 women planned for elective cesarean delivery and desired IUD as a contraceptive method. They were allocated into two groups; group I, in which IUD was inserted during LSCS, and group II, in which IUD was inserted six weeks or more after LSCS. Both groups were compared regarding failed insertion, post-insertion pain, and uterine perforation. They were followed for one year for the incidence of menorrhagia, vaginal infection, IUD displacement/expulsion, missed threads, or unintended pregnancy. RESULTS Women in the second group showed a significantly higher incidence of failed insertion and uterine perforation than women in the first group. On the contrary, women in the first group showed a significantly higher incidence of missed threads than women in the second group. Regarding other consequences, there were no significant differences between both groups concerning menorrhagia, vaginal infection, IUD displacement/expulsion, or unintended pregnancy. CONCLUSION IUD insertion during elective LSCS showed a significantly lower incidence of failed insertion and uterine perforation than its insertion six weeks postoperative.

Abstract
Background This study aims to detect the effects of increased BMI on labor outcomes in primigravida pregnant women. Methods A cross-sectional study involved 600 full-term singleton primigravida pregnant women who presented in the active phase of labor to the labor ward. They were divided according to BMI into three equals groups; women with normal BMI (group I), overweight women (group II), and women with class I obesity (group III). Results We found that high BMI was associated with a significantly increased risk of Caesarean section (C.S.) (13% in group I, 18% in group II and 40% in group III). Women with higher BMI and delivered vaginally had a significantly prolonged first and second stage of labor, consequently increased the need for oxytocin augmentation as well as the oxytocin dose. Regarding the maternal and fetal outcomes, there are significantly increased risks of postpartum sepsis, perineal tears, wound infection, as well as significantly increased birth weight and longer neonatal stay in the neonatal unit (NNU). Conclusion Obese primigravida pregnant women were at higher risk of suboptimal outcomes. Besides, prolonged first and second stages of labor and the incidence of C.S. have also been increased.

Abstract
In dairy calves raised for veal, typical clinical signs of bovine respiratory disease (BRD) are ocular discharge, nasal discharge, ear droop or head tilt, abnormal respiration, cough, and increased rectal temperature. Despite the existence of several clinical scoring systems, there are few studies on the variability of human recognition of individual BRD clinical signs. The objective of this study was therefore to assess the inter-rater agreement of BRD clinical signs in veal calves. We hypothesized that BRD clinical signs were not detected equally between veterinarians, technicians, and producers of the veal industry and that some clinical signs have higher inter-rater agreement than others. During 2017-2018, we prospectively recorded 524 videos of physical examinations of random veal calves from 48 different batches in Québec, Canada. A researcher, not involved in the inter-rater assessment, classified each video as presence/absence of each BRD clinical sign except rectal temperature. For each of the 5 clinical signs, 15 videos with and 15 videos without the clinical signs were randomly selected to avoid kappa paradoxes. Those 30 videos were then presented in a random order to experienced raters of BRD in veal calves: 6 veterinarians, 6 technicians, and 6 producers. The raters assessed the clinical signs using scores based on the Wisconsin and California scoring system with modifications (0 = absent, 1 = mild, 2 = moderate, 3 = severe for nasal discharge, ocular discharge, and ear droop or head tilt; and 0 = absent, 1 = moderate, 2 = severe for abnormal respiration and induced cough). We used median percentage agreement (Pa), median Cohen's kappa (κ), and Gwet's agreement coefficient 1 (AC1) to assess inter-rater agreement. The effect of scale combination was also tested to determine the optimal combination (4-scale 0/1/2/3 vs. 3-scale 0/1/2 vs. 2-scale 0/1,2,3; 0,1/2,3; or 0/1,2). The differences of inter-rater agreement between veterinarians, technicians, and producers were estimated by a Wilcoxon rank-sum test. The 2-scale combination (0,1/2,3 or 0/1,2) had the highest inter-rater agreement for all clinical signs. With this combination, induced cough was the clinical sign with the highest inter-rater agreement (Pa = 0.93; κ = 0.79; AC1 = 0.87) and abnormal respiration was the sign with the lowest inter-rater agreement (Pa = 0.77; κ = 0.20; AC1 = 0.74). According to Pa and AC1 values, the 2-scale inter-rater agreement of the 5 clinical signs was good (value > 0.6). According to κ, only ear droop or head tilt and induced cough had a substantial 2-scale inter-rater agreement (κ > 0.6). In general, the 2-scale inter-rater agreement was better among veterinarians than among technicians and producers, except for the ear droop/head tilt, where agreement was better among producers. We concluded that with severity scores assessed on a scale of 2 (0,1/2,3 or 0/1,2), the inter-rater agreement of BRD clinical signs was variable according to the sign in veal calves. BRD clinical signs were not detected equally between veterinarians, technicians, and producers of the veal industry. Future research could determine if this discrepancy could be improved by standardization training.

Abstract
Equine gastric ulcer syndrome (EGUS) is a communal broad problem in equines but in donkeys, the disease is a subclinical disorder which leads to economic losses. Gasterophilus intestinalis larvae are the most predominant parasitic infestation in donkeys. The present study was planned to facilitate the early and efficient diagnosis of gastric ulceration in donkeys through gastroscopic examination. The study was conducted on 120 adult Egyptian donkeys (Equus asinus) from both sexes after a one-month acclimatisation period. Gastroscopic examination was used to evaluate the presence of gastric lesions. In the majority of infested donkeys, G. intestinalis larvae were in the non-glandular part of the stomach. The prevalence of Gastrophilus larvae in animals reached 96.66%. The infestation percentage among jennets (97.5%) was slightly higher than that among jacks (96.25%). After morphological identification of the 3rd instar of larvae, all donkeys were found to be infested by G. intestinalis larvae. The histopathological examination of the affected stomach revealed severe necrosis of the gastric mucosa. Gastroscopic examination is the main diagnostic tool for examination of gastric lesions in the donkeys, so it is necessary as a routine diagnostic tool in donkeys’ examinations.

Abstract
OBJECTIVE To assess the efficacy of first-trimester three-dimensional (3D) placental volume as well as 3D power Doppler of placental vascular indices for early prediction of pre-eclampsia. METHODS The prospective cohort study included over 2019 women with a singleton pregnancy in their first trimester at 11-13+ weeks of pregnancy. All women were examined by 3D abdominal ultrasound, including Doppler techniques for the placental volume and placental vascular indices. Uterine artery Doppler indices were also assessed. All participants were cared for until delivery for assessment of pregnancy outcomes. RESULTS In all, 163 women developed pre-eclampsia while 1856 women remained normotensive. The women with pre-eclampsia had significantly lower placental volume (77.09 ml vs. 99.8 ml, p < 0.001), and placental vascular indices (vascularization index, flow index, and vascularization flow index were 7.41 vs. 9.89, 39.03 vs. 46.63, and 2.77 vs. 4.4, respectively, p < 0.001). In contrast, women with pre-eclampsia had significantly high mean uterine pulsatility index and resistance index (2.02 vs. 1.11, 0.83 vs. 0.64, respectively, p < 0.001) compared with the normotensive women. The placental vascular indices were highly sensitive, whereas the placental volume and the mean uterine pulsatility index and resistance index had higher specificity for the prediction of pre-eclampsia. CONCLUSION First-trimester assessment through 3D placental volume and power Doppler of placental vascular indices, especially in combination with uterine artery Doppler assessment, revealed an increase in the accuracy of early detection of women at risk for developing pre-eclampsia.

Abstract
Both 2-D and 3-D transvaginal ultrasonography are effective imaging modalities for assessment of ovarian reserve. Our aim was to compare both modalities in assessment of ovarian reserve of women undergoing in vitro fertilization/intra-cytoplasmic sperm injection (IVF/ICSI). Fifty women were scheduled according to their menstrual cycle to be examined by both 2-D and 3-D transvaginal ultrasonography. We found that the average time for computerized analysis of the 3-D ultrasound data was significantly shorter than that for analysis of the 2-D ultrasound data, for both total antral follicle count and ovarian volume. However, there were no statistically significant differences between the methods in total antral follicle count and ovarian volume. We conclude that, where available, 3-D ultrasonography can be used for assessment of ovarian reserve in addition to the biochemical marker, particularly in overcrowded in vitro fertilization centers that need to save time.

Background: Breast cancer is the most common malignancy among adults in Jordan accounting for 39.4% of all newly diagnosed cancers. Jordan is a lower-middle–income country that lacks national screening program. King Hussein Cancer Foundation/Center (KHCF/KHCC) and Jordan Breast Cancer Program had put significant efforts over past years to increase awareness about breast cancer and improve mammography services. They have introduced two mobile mammography units aiming at reaching women in their local communities, in underserved and underprivileged regions. Aim: Describe the experience of making mammography accessible and free of charge to women in rural and remote areas with limited access to mammography services. Methods: Local health educators were trained to recruit women aged 40 years and above to get free screening mammogram in mobile mammography unit. Data collected from five rural areas in Jordan from 2012 until 2017. Total number is 13570 women. Recall was performed at the fixed mammography unit at KHCC and was free of charge until the diagnosis of cancer affirmed or deferred. Results: The highest percentage of women 55.2% (N: 7733) aged 41-50 years. Women aged less than 40 years were recruited due to their breast-related symptoms. It was ethically difficult to refrain imaging symptomatic women in van in remote areas. However, in areas closer to KHCC symptomatic women with no medical insurance were directly referred to KHCC with voucher for free mammogram and workup. Total number of women referred for screening was 13058 (96.2%) and those referred as diagnostic was 512 (3.8%); their mean age was 48.8 and 45 years respectively. Overall recall rate was 29.3% (N: 3822) among screening cases. Cancer detection rate was 0.85% (N: 112) among screened women and 6.8% (N: 35) among diagnostic cases. Number of women who failed to adhere to follow-up procedures was N=1191 (8.8%). It was noticed that family history of cancer correlated with better adherence to complete follow-up procedures. Conclusion: Mobile mammography unit enabled access to screening mammography in rural areas and also encouraged symptomatic women to seek medical advice early. Ensuring financial coverage may have been an additional motivational factor. Follow-up studies may be conducted to compare tumor size differences between screening and diagnostic cases, prognosis and quality of life.

Abstract
OBJECTIVE The current study aims to assess the efficacy of fetal middle cerebral artery/umbilical artery pulsatility index ratio (cerebroplacental ratio CPR) in predicting the occurrence of adverse perinatal outcomes in pregnancies complicated with severe pre-eclampsia. MATERIALS AND METHODS This cohort study included 100 pregnant women between 34 and 40 weeks of gestation attended the labor ward and diagnosed with severe pre-eclampsia. Doppler evaluation was carried out to measure the CPR. Apgar score and fetal umbilical artery pH were assessed within 5 min of delivery. The rate of neonatal intensive care unit (NICU) admission was obtained. RESULTS Apgar score at 5 min >7 was in 82 cases (82%) and 12 cases (12%) scored < 7. Fetal blood PH was >7.2 in 67% of cases while 33% of cases had PH <7.2. As regard the NICU admission; 66% of neonates did not need admission while 34% of neonates were admitted to the NICU. There was a significant association between CPR and low Apgar score at 5 min (P < 0.001). The sensitivity of CPR in detection of Apgar score <7 was 50%, and specificity 88.1%. CPR had a poor predictive value of the low umbilical artery PH <7.2 (P = 0.318) with 43.75% sensitivity and 69.05% specificity. There was a significant association between CPR and NICU admission (P = 0.009). CONCLUSIONS Adding CPR ratio to routine antepartum fetal surveillance from 34 weeks gestation may help with patient counseling regarding adverse neonatal outcomes for women with severe pre-eclampsia as there is a strong correlation between it and adverse neonatal outcomes.

Abstract
Surgical treatment for stress urinary incontinence (SUI) using transobturator tape insertion is widely accepted. However, several postoperative complications were reported in the literature including infections, abscess and fistula formation. Here, we report a case of 57-year-old female who presented with abscess and left vaginocutaneous buttock fistula 7 years after transobturator polypropylene tape insertion. Treatment included abscess drainage with dissection of the fistulous tract and removal of the left arm of the transobturator tape along with antibiotic coverage. Sinus drainage stopped after 3 days. Stress urinary incontinence did not recur. Suspicion of fistula formation should rise in patients presenting with bothersome vaginal or cutaneous discharge after transobturator tape insertion. This case is particular since it describes a fistula complication with polypropylene tape, which is unusual with this type of tapes. Treatment of such complication should always consist of surgical removal of the mesh to allow closure of the fistulous tract.

Abstract
BACKGROUND Bovine respiratory disease (BRD) is a worldwide animal health concern especially in feedlot, dairy, and veal calves. One of the greatest challenges is the absence of a gold standard for achieving an accurate antemortem diagnosis. Various blood markers, including the acute-phase proteins (AAP), have been proposed as potential valuable tools for BRD diagnosis. OBJECTIVES To perform a systematic review of the literature to assess the accuracy of selected APP (haptoglobin [Hp], serum amyloid A [SAA], and fibrinogen [Fb]) as diagnostic tools for cattle with naturally occurring BRD when compared with clinical reference standards of diagnosis. METHODS This review was performed with eligible studies selected from CAB Abstract and MEDLINE from 1946 to 2015, as well as the "gray literature." Methodological quality of included studies was assessed using the QUADAS-2 tool developed for diagnostic accuracy studies. The accuracy parameters sensitivity (Se) and specificity (Sp) were obtained from the articles or through contact with the authors when not directly reported. RESULTS A total of 314 studies were identified, from them, 23 met inclusion criteria as diagnostic studies for naturally occurring BRD. Quality of studies showed high risk of bias for case selection (70% of articles) and unclear risk of bias for index test (65%), reference standard (74%), and flow and timing (61%). There were high concerns regarding applicability for case selection (61% of studies) and reference standards used for defining BRD (48%). The concerns regarding index test application were low (83% of the studies). Only 4-8 studies could be included in the meta-analysis for each APP. No pooled estimates or pooled accuracy measurements were performed due to the low number of studies and multiple differences between studies, including reference standard definitions. CONCLUSIONS AND CLINICAL IMPORTANCE On the basis of these findings, it is not possible to make conclusions regarding the accuracy of APP for BRD diagnosis. The reporting of accuracy of APP for BRD detection is inconsistent among studies. Recommendations to improve capability for future meta-analyses in this area include reporting studies on diagnostic tests following the Standard for the Reporting of Diagnostic Accuracy Studies (STARD), as well as trying to standardize BRD definition across future studies.

Abstract
BACKGROUND The GeparQuinto study showed that adding bevacizumab to 24 weeks of anthracycline-taxane-based neoadjuvant chemotherapy increases pathological complete response (pCR) rates overall and specifically in patients with triple-negative breast cancer (TNBC). No difference in pCR rate was observed for adding everolimus to paclitaxel in nonearly responding patients. Here, we present disease-free (DFS) and overall survival (OS) analyses. PATIENTS AND METHODS Patients (n = 1948) with HER2-negative tumors of a median tumor size of 4 cm were randomly assigned to neoadjuvant treatment with epirubicin/cyclophosphamide followed by docetaxel (EC-T) with or without eight infusions of bevacizumab every 3 weeks before surgery. Patients without clinical response to EC ± Bevacizumab were randomized to 12 weekly cycles paclitaxel with or without everolimus 5 mg/day. To detect a hazard ratio (HR) of 0.75 (α = 0.05, β = 0.8) 379 events had to be observed in the bevacizumab arms. RESULTS With a median follow-up of 3.8 years, 3-year DFS was 80.8% and 3-year OS was 89.7%. Outcome was not different for patients receiving bevacizumab (HR 1.03; P = 0.784 for DFS and HR 0.974; P = 0.842 for OS) compared with patients receiving chemotherapy alone. Patients with TNBC similarly showed no improvement in DFS (HR = 0.99; P = 0.941) and OS (HR = 1.02; P = 0.891) when treated with bevacizumab. No other predefined subgroup (HR+/HER2-; locally advanced (cT4 or cN3) or not; cT1-3 or cT4; pCR or not) showed a significant benefit. No difference in DFS (HR 0.997; P = 0.987) and OS (HR 1.11; P = 0.658) was observed for nonearly responding patients receiving paclitaxel with or without everolimus overall as well as in subgroups. CONCLUSIONS Long-term results, in opposite to the results of pCR, do not support the neoadjuvant use of bevacizumab in addition to an anthracycline-taxane-based chemotherapy or everolimus in addition to paclitaxel for nonearly responding patients.

Abstract
Introduction Non invasive positive pressure ventilation (NIPPV) is the first line treatment for hypercapnic acute respiratory failure (ARF) secondary to COPD exacerbation in selected patients. Limited data exist supporting the use of fiberoptic bronchoscopy (FOB) during this clinical setting. The aim of this study is to assess the role of FOB during NIPPV in patients with decompensated COPD acute exacerbation. Methods This study is a randomized prospective case control pilot study carried out on 50 patients - admitted to critical care units at Alexandria University Hospital, Egypt - suffering from hypercapnic ARF secondary to COPD exacerbation with Kelly Matthay Score from 2 to 4. All patients received NIPPV. Patients were divided randomly into 2 equal groups: group I (cases) (25 patients) was subjected to additional intervention of early FOB during the first 6–12 h from admission while group II (control) (25 patients) received the conventional treatment and NIPPV only. Outcome parameters measured were changes in ABG data, duration of NIPPV, rate of its success, ICU stay and mortality as well as the safety of FOB and possible complications. Results No significant difference was detected between the 2 groups regarding the baseline characteristics. No serious complications happened from FOB, and Oxygen desaturation happened in 4/25 patients (16%), Tachycardia in 2/25 patients (8%). In group I, 23 patients (92%) were successfully weaned from NIPPV versus 16 patients (64%) in group II (p = 0.037). Total duration of NIPPV was 28.52 h in group I versus 56.25 h in group II (p = 0.001). Length of ICU stay was 4.84 days in group I versus 8.68 days in group II (p = 0.001). Only 1 patient died in group I versus 3 patients in group II (p = 0.609). Conclusion The early application of FOB during NIPPV in patients with ARF due to COPD exacerbation was shown to be safe. Significant improvement in the outcome of patients who underwent FOB was noticed in terms of improved ABG data, shorter duration of NIPPV, higher percentage of success and shorter ICU stay while no significant difference was detected in mortality.

Abstract
There are eight reported cases in the literature of osteosarcomas secreting β-hCG. Our primary aim was to investigate the rate of β-hCG expression in osteosarcoma and attempt to understand the characteristics of osteosarcomas that secrete β-hCG. We reviewed 37 histopathology slides (14 biopsies and 23 surgical specimens) from 32 patients with osteosarcoma. The slides were retrospectively stained for β-hCG expression. Patient and tumour characteristics, including age, gender, tumour location, subtype, proportion of necrosis, presence of metastases and recurrence were recorded. A total of five of the 32 tumours were found to be positive for β-hCG expression (one strongly and four weakly). This incidence of this expression was found in tumours with poor histological response to neoadjuvant chemotherapy. The use of β-hCG expression as a diagnostic, prognostic or follow-up marker is questionable and needs further investigation with a larger sample size.

Abstract
Abstract
Background
Neoadjuvant chemotherapy (NT) has become an important approach to assess therapeutic efficacy of new treatment strategies. We observed a predictive role of of serum HER2 (sHER2) with neoadjuvant trastuzumab treatment in the previous trial “Geparquattro”. Predictive markers for response to new HER2−targeted therapies are still lacking. Therefore, we investigated the role of sHER2 in the context of trastuzumab and lapatinib treatment.
Methods: The clinical trial Geparquinto incorporated either trastuzumab or lapatinib treatment combined with chemotherapy for HER2−positive breast cancer patients. Serum samples were taken at three different time points: before initiation of NT, after 4 cycles of chemotherapy with epirubicin and cyclophophamide and after finalization of NT with 4 cycles of docetaxel (pre-surgery). Only those patients were included in the analysis with serum available at all three time points. sHER2 levels were measured by a commercially available ELISA in 159 patients with a HER2−positive primary tumor, 77 (48%) patients were treated with trastuzumab, 82 (52%) with lapatinib. Pathological complete remission (pCR) was defined as no microscopic evidence of invasive residual tumor cells in the breast and lymph nodes.
Results: Overall pCR rate in this cohort was 28%. sHER2 levels were higher in patients with larger tumors (> 5cm, p=0.012) and positive nodal status (p=0.001). Higher pre-chemotherapy sHER2 levels were associated with higher pCR rates in the entire study cohort (OR 2.9, 95% CI 1.3−6.7, p=0.012). Additionally, in the lapatinib treated patient group, a decrease of serum levels of more than 20% after 4 cycles of chemotherapy showed a tendency to be associated with higher pCR rates (OR 7.7, 95% CI 0.8- 70, p=0.071). In contrast to the finding of the previous trial Geparquattro, this was not the case in the trastuzumab-treated patient group (p=n.s.).
Conclusion: Results of this study demonstrate pre-chemotherapy sHER2 levels to be an independent predictor of response to NT with both trastuzumab and lapatinib treatment.

Abstract
Sarcoidosis and Crohn's disease are heterogeneous systemic diseases characterised by granulomatous inflammation. Caspase recruitment domain (CARD)15 is a major susceptibility gene for Crohn's disease, and specifically for ileal and fibrostenotic subtypes. The C-C chemokine receptor (CCR)5 gene has been associated with both parenchymal pulmonary sarcoidosis and perianal Crohn's disease. This study explored associations between CARD15 polymorphisms, CCR5 haplotype and distinct pulmonary sarcoidosis subtypes. 185 Caucasian sarcoidosis patients were genotyped for CARD15 and CCR5 polymorphisms. The genetic data were compared with 347 healthy controls and were examined for associations with serial pulmonary function tests and chest radiographs. CARD15 genotypes did not differ between the unselected sarcoidosis cohort and controls. However, patients carrying the functional 2104T (702W) polymorphism were more likely to have radiographic stage IV disease at 4-yr follow-up. All patients possessing both CARD15 2104T and CCR5 HHC haplotype had stage IV disease at presentation. Carriage of 2104T was associated with worse forced expiratory volume in 1 s, whereas carriage of the CARD15 1761G (587R) polymorphism was associated with better lung function. For the first time, an association between two CARD15 polymorphisms and specific sarcoidosis phenotypes has been demonstrated, as well as an additive effect of possessing CARD15 2104T and CCR5 HHC haplotype.

Abstract
The phylloid tumor (PT, formerly called cystosarcoma phylloides) is a rare neoplasia of the female breast. Usually the PT is treated with breast-conserving surgery. In spite of progress in early diagnosis, PTs recur frequently--independently of tumor's degree of malignancy. Especially in cases of malignant PT, complete resection with tumor-free margins is seen as the only predictive marker for tumor recurrence or metastases. Benign PT is also often resected with wide tumor-free margins. Because of the tumor's occasionally enormous dimensions, this therapy concept makes breast-conserving surgery almost impossible. A simple enucleation of benign PT is an option to facilitate the preservation of breast tissue and a cosmetically satisfactory breast reconstruction. In the case of particularly large benign PT, enucleation even without wide margins prevents tumor recurrence.

Abstract
In granulomatous inflammatory lung diseases such as sarcoidosis, the balance of cytokine production by activated T cells in the lungs may influence clinical disease outcome. To investigate the potential of T lymphocytes to produce cytokines and contribute to this process, T cells from bronchoalveolar lavage (BAL) and PB from 19 patients with active lung disease were stimulated, stained, and analysed by flow cytometry for intracellular production of cytokines and expression of the activation marker CD69. Higher proportions of BAL cells expressed CD69 compared with PB, in the absence of in vitro stimulation. The expression of IFN-gamma was similar in unstimulated BAL and PB T cells, and there was no association between the expression of CD69 and IFN-gamma. Following stimulation, there were increased numbers of IFN-gamma(+) T cells. A similar trend was found with IL-2(+) T cells, but there were lower levels of IL-4(+) T cells in BAL compared with PB, and similar levels of IL-10(+) T cells. The presence of activated T lymphocytes in BAL samples from patients with sarcoidosis, with the potential to produce Th1 type 1 cytokines may contribute to the inflammatory processes in this granulomatous lung disease. The use of intracellular flow cytometry to investigate cytokine production by BAL T cells could help to indicate potential targets for future therapy.

Abstract
BACKGROUND The undescended testis represents one of the most common disorders of childhood. The authors evaluated the safety and efficacy of laparoscopy for the abdominal testis and present a classification of the laparoscopic diagnostic findings to facilitate decision making. METHODS Between 2000 and 2005, 95 patients (22 bilateral and 73 unilateral testes, for a total of 117 impalpable testes) with a mean age of 5 years underwent laparoscopy. The testis was managed according to a special classification of the diagnostic findings. Testicular position, size, and viability according to technetium-99m ((99m)Tc) were assessed during the follow-up evaluation. RESULTS The laparoscopic findings were classified into six types: type 0 (no testis or vanished testis proximal to the internal ring; 9 patients [7.5%]); type 1 (atrophic intracanalicular testis; 6 patients [5.4%], for whom no further intervention was administered); type 2 (testis at the internal ring with looping vas; 15 patients [14.5%], for whom laparoscopic orchiopexy was performed); type 3 (testis at the internal ring without looping of the vas; 29 patients [24.7%], for whom laparoscopic orchiopexy also was performed; type 4 (high abdominal testes; 49 patients [41.9%], with Staged Fowler-Stephens orchiopexy performed for 47 testes and laparoscopic orchidectomy for 2 testes; and type 5 (persistence of Müllerian duct structures [PMDS] or other abnormalities; 7 testes [6%]). After a mean follow-up period of 3 years, the laparoscopic orchiopexy testes were of good size and viable, but four testes (8.7%) were at the neck of the scrotum. The laparoscopically staged Fowler-Stephens orchiopexy group showed atrophy in two testes (4.3%), and all were in the bottom of the scrotum. CONCLUSIONS Classification of the laparoscopic findings facilitates decision making. Laparoscopic orchiopexy is a natural extension of diagnostic laparoscopy for the intraabdominal testis at the internal ring or that seen peeping from it. Laparoscopically staged Fowler-Stephens orchiopexy is the procedure of choice for the high intraabdominal testis not amenable to the one-stage procedure.

Abstract
BACKGROUND EEG wicket rhythms are 6- to 11-Hz medium-to-high voltage bursts that are sometimes misidentified as epileptogenic activity. The authors determined the clinical and EEG features of patients with wicket rhythms who had been incorrectly diagnosed with epilepsy. METHODS Electroencephalographers at an epilepsy center re-read EEGs for patients referred for epilepsy management and identified patients with wicket rhythms. On further evaluation, the majority (54%; 25/46) of these patients were found not to have epilepsy. The authors compared the clinical and EEG features for the 25 patients with wickets and nonepileptic episodes with those of age- and sex-matched patients with partial-onset epilepsy using univariate and multivariate analysis. RESULTS Several features distinguished patients with EEG wicket patterns and nonepileptic episodes (n = 25) from age- and sex-matched patients with epilepsy (n = 25): mid-adult age at onset of episodes (mean 38.4 years vs 19.8 years), prolonged clinical episodes (mean 155 minutes vs 2.3 minutes), and long duration of EEG wicket patterns (mean 0.66 seconds vs 0.11 second spikes). After controlling for other factors, patients without major confusion during episodes were unlikely to have epilepsy. CONCLUSION Wicket patterns are often interpreted as epileptogenic. This distinctive EEG pattern should be considered in patients with clinical episodes atypical for epilepsy.

Abstract
Transforming growth factor-beta1 (TGF-beta1) plays an important role in the pathogenesis of systemic sclerosis (SSc). To investigate the role of TGF-beta1 gene polymorphisms in SSc, we genotyped six biallelic polymorphic positions (position -988, -800, and -509; and codons 10, 25, and 263) in 61 Korean SSc patients and in 148 healthy controls, using polymerase chain reaction-sequence-specific primers. Genetic polymorphisms were found at position -509 and codon 10 in Koreans. The allele frequencies of C/T at position -509 were 0.59/0.41 in patients and 0.56/0.44 in controls. The allele frequencies of C/T at codon 10 were 0.40/0.60 in patients and 0.50/0.50 in controls. In conclusion, no skewed distribution of TGF-beta1 gene polymorphisms was found in Korean patients with SSc.

Abstract
The aetiology of sarcoidosis is uncertain; current thinking implicates exposure of genetically susceptible hosts to environmental factors. The nuclear factor kappa B (NF-kappaB) family of transcription factors are critical regulators of immediate transcriptional responses in inflammatory situations and immune responses. Inhibitor kappa B-alpha (IkappaB-alpha) inhibits NF-kappaB and plays a major role in controlling its activity. We investigated IkappaB-alpha promoter polymorphisms using sequence-specific primer-polymerase chain reaction, at positions -881 (A/G), -826 (C/T), and -297 (C/T) in Caucasian sarcoidosis patients (UK and Dutch [NL]), each with their own controls. Disease severity at presentation was assigned using chest radiography and pulmonary function indices. In the combined populations, the -297T allele carriage was more prevalent in patients than in controls (P=0.008). Three common haplotypes were found, of which haplotype 2 (GTT) was significantly associated with sarcoidosis in comparison with control subjects (P=0.01). Subgroup analysis revealed that the -826T allelic carriage was most prevalent in stage II disease, and more prevalent in stage III than in stage IV (P=0.01). The -826T allelic carriage did not show any association with lung function. These results indicate that the NF-kappaB activation pathway might be associated with the inflammation of sarcoidosis.

Abstract
Immunocompromised haematological patients are at high risk for severe, often fatal, respiratory syncytial virus (RSV) pneumonia. In the 2001 winter season, 16 of 195 (8.2%) adult haematological in-patients were diagnosed with RSV infection. Eight patients had undergone stem cell transplantation. The median age was 53 years (range 20-67). A total of 11 patients had nosocomial RSV infection while the rest (five) had community-acquired infection. All patients were febrile and had upper respiratory tract infection (URTI). Eight patients (50%) developed lower RTI. Two of the 16 patients (12.5%) died of respiratory failure, due to the RSV pneumonia, despite ICU admission and supportive ventilation. None of the studied patients received ribavirin therapy or specific RSV immunoglobulin. Two patients autografted for multiple myeloma (MM) showed delayed neutrophil and platelet engraftment despite receiving an adequate dose of stem cells. A third patient undergoing a CD34+ selected HLA-matched sibling mini-allograft for relapsed MM showed graft failure shortly after RSV infection. In our series, RSV infection was concurrent with an outbreak in the community. Unlike other published series, no specific antiviral treatment for RSV pneumonia was used and yet the overall outcome in our patients was favourable. Furthermore, RSV infection in the pre-engraftment period after autologous transplantation was associated with delayed engraftment.
