Abstract
The expression of the programmed cell death protein 1 (PD-1) has been shown to be markedly increased in tumor-infiltrating lymphocytes. However, the proportion of PD-1 + T cells in the bronchoalveolar lavage (BAL) of lung cancer patients has not been sufficiently evaluated so far. In this prospective study, the proportion of PD-1 + CD4 + as well as PD-1 + CD8 + T cells in BAL samples, isolated from patients with lung cancer, asthma or interstitial lung disease (ILD), were determined via flow cytometry and compared for differences. Bronchoalveolar lavage was performed in 34 patients (14 patients with lung cancer, 10 patients with asthma, 10 patients with ILD). The highest median proportion of PD-1 + CD4 + or PD-1 + CD8 + T cells were found in patients with ILD (83.1% [IQR 72.1; 87.5] and 73.8% [IQR 60.3; 86.3]) followed by patients with lung cancer (66.4% [IQR 59; 69] and 77.1% [IQR 35.8; 82.3]) and patients with asthma (61.3% [IQR 57.4; 70.5] and 57.3% [IQR 46; 65]). Thereby, the difference in the proportion of PD-1 + CD3 + CD4 + BAL cells between ILD patients and asthmatics was significantly different (p = 0.04). The proportion of PD-1 + CD4 + and PD-1 + CD8 + T cells in the BAL of patients with lung cancer did not differ significantly to patients with benign lung diseases. The highest proportion was observed in ILD patients suggesting further research to evaluate the role of the PD-1/PD-L1 pathway in ILD patients.

Abstract
BACKGROUND AND AIM Combined use of surgical mask with filtering facepiece (FFP) 2 masks has been popular among the health-care workers. However, the effect of this preference on the vital values of individuals stays as a challenge among the professionals. The present study aimed to assess the effect of FFP2 mask versus combined use of it with surgical mask on the SpO2 values and pulse rates of individuals. PATIENTS AND METHODS This study was conducted on 20 health-care workers. The pulse rates and SpO2 values were evaluated by pulse oximeter placed in the index fingers of the participants. The participants were divided into two groups: those using the FFP2 mask and those using FFP2-surgical mask combination. Individuals wearing FFP2 mask were examined for a period of 60 min and the same examination was repeated for another period of 60 min in those using combination of FFP2 with surgical mask. The values were measured at the beginning and at 15, 30, 45, and 60 min intervals, respectively. The examinations were conducted in the rest position to obtain standardization. RESULTS The observed data showed no statistical difference at all periods in either SpO2 values or pulse rates between FFP2 and FFP2-surgical mask combined groups. The SpO2 values reduced from the initial time to 15 min in the FFP2-surgical mask group. Also, in the FFP2-SM group, statistically significant increase in values was observed between 15 and 45 min and 15 and 60 min. Another increase in SpO2 value was found in the observations made between made 30 and 45 min in the same group (P < 0.05). The pulse rates of the individuals showed no statistical difference in both the groups and at all experimental periods (P > 0.05). CONCLUSION According to the present study, wearing only the FFP2 mask or FFP2-surgical mask combination seems not to cause any effect on the SpO2 values and pulse rates of the participants.

Abstract
Mushrooms are cosmopolitan organisms living on different substrates and have different pharmacological properties, such as antioxidant, antimicrobial, and anti-inflammatory effects thanks to many bioactive compounds. Edible and medicinal higher fungi have been used by humankind for millennia. They are collected and used directly not only for their nutritional values as a main source of food or as a part of a regular diet but also for their medicinal purpose as a source of powerful new bioactive compounds. Antioxidative and anti-inflammatory functions and therefore lipid-lowering effects correlate with antiatherogenic effects. This study determined the total antioxidant capacity (TAS), total oxidant capacity (TOS), oxidative stress index (OSI), 1-diphenyl-2-picrylhydrazyl (DPPH) activity, and antimicrobial activity of ethanolic and methanolic extracts of Stereum hirsutum (Willd.) Pers. Moreover, the effects on atherosclerosis are discussed according to the antioxidant activity of the mushroom. The TAS, TOS, and OSI values of S. hirsutum were determined using Rel Assay kits. According to the results, the TAS, TOS, and OSI values were determined at 5.289&plusmn;0.113 mmol/L, 20.540&plusmn;0.416 &mu;mol/L, and 0.389&plusmn;0.012. Furthermore, free radical scavenging activity was determined by the DPPH method. The ethanol (EtOH) extracts of S. hirsutum showed higher DPPH activity than methanol extracts. The EtOH extracts at a concentration of 2 mg/mL showed a DPPH inhibition of 45.84&plusmn;0.81%. Antimicrobial activities were tested on 9 standard bacterial and fungal strains, including Staphylococcus aureus, S. aureus MRSA, Enterococcus faecalis, Escherichia coli, Pseudomonas aeruginosa, Acinetobacter baumannii, Candida albicans, C. krusei,and C. glabrata using a modified agar dilution method. Extracts showed high activity against S. aureus, S. aureus MRSA, and A.baumannii. In conclusion, it was suggested that S. hirsutum can be used as a natural source related to the effects on atherosclerosis due to its antioxidant and antimicrobial activities.

Abstract
Purpose This study aims at determining lung distribution of gadolinium-based polysiloxane nanoparticles, AGuIX® (small rigid platform - SRP), as a potential theranostic approach by the pulmonary route. Methods First, the aerodynamic size distribution and the aerosol output rate were thoroughly characterized. Then, a multimodal approach using magnetic resonance (MR) and gamma-camera (GC) imaging allows to assess the deposition of the aerosolised nanoparticles in the respiratory tract using isolated ventilated porcine lungs. Results The SRP has proven to be radiolabelled by radioisotope with a good yield. Crude SRP or radiolabelled ones showed the same aerodynamic size distribution and output as a conventional molecular tracer, as sodium fluoride. With MR and GC imaging approaches, the nebulised dose represented about 50% of the initial dose of nanoparticles placed in the nebuliser. Results expressed as proportions of the deposited aerosol showed approximately a regional aerosol deposition of 50% of the deposited dose in the lungs and 50% in the upper airways. Each technique assessed a homogeneous pattern of deposited nanoparticles in Lungs. MR observed a strong signal enhancement with the SRP, similar to the one obtained with a commonly used MRI contrast agent, gadoterate meglumine. Conclusion As a known theranostic approach by intravenous administration, SRP appeared to be easily aerosolised with a conventional nebuliser. The present work proves that pulmonary administration of SRP is feasible in a human-like model and allows multimodal imaging with MR and GC imaging. This work presents the proof of concept of SRP nebulisation and aims to generate preclinical data for the potential clinical transfer of SRP for pulmonary delivery.

Abstract
PURPOSE The objective of this study is to evaluate the suitability and performance of ultra-short echo time (UTE) sequences for imaging and quantifying the deposition of nebulized MRI contrast agents in human-sized lungs. METHODS Nebulization of clinically used contrast agent or gadolinium-based nanoparticles were performed using a commercial jet nebulizer in isolated and ventilated porcine lungs connected to a 3D-printed human upper airways replica. MR images of isolated lungs were acquired on a 3T clinical MR scanner using 3D UTE sequences at different flip angles. RESULTS 3D acquisitions with isotropic millimetric resolution were obtained in less than 4 min. Images exhibit homogeneous and large MR signal enhancement (above 200%) following nebulization of both types of aerosols. Deposition of aerosol down to the level of the bronchi of secondary lobules was visualized. T1 values and the concentration of nanoparticles obtained by MRI were found to correlate with the amount of nebulized gadolinium3+ ions. CONCLUSION The distribution of aerosolized gadolinium-based contrast agent or nanoparticles can be visualized and quantified using UTE MRI in large animal ventilated lung model on a clinical MRI scanner. This protocol can be used for assessing and quantifying aerosol regional deposition with high spatial resolution (1 mm 3D isotropic) without ionizing radiation and could be applied in the future for diagnostic or therapeutic applications in patients.

Abstract
SummaryRecombiplastin, a recombinant a human tissue factor, elaborated by Ortho Diagnostic Systems, produced by Baculovirus and relipidated with highly purified phospholipids, was tested as a new reagent for determining prothrombin time (PT) in a French multicentric study. Its intralaboratory- performances, including sensitivity, repeatability, reproducibility and stability, were explored to establish whether its use would reduce the interlaboratory dispersion of PT values, and therefore improve the standardization of oral anticoagulant treatment.The 9 university hospital hematology laboratories involved in this study used the same type of instrument (KC 10). For 10 consecutive days, they determined PTS on a normal plasma pool, plasma dilutions of 1/2, 1/3 and 1/8, 3 identical lyophilized calibrated plasmas, as well as plasmas from 20 normal subjects, 50 patients on oral anticoagulant therapy with Recombiplastin which has an International Sensitivity Index (ISI) of 1, and 2 commercial thromboplastin extracts (ISI #1 or 2). In the patients on anticoagulants, factors VII, X and V were measured when results were conflicting.The intra and interlaboratory reproducibilities of Recombiplastin, calculated on the basis of either PTS expressed in seconds, or of the International Normalized Ratio (INR), were good, with coefficients of variation (CV) similar to those observed with the 5 other reagents used by the different laboratories (2% <CV <8%).The stability of Recombiplastin was excellent, with no variation in PT after 72 h of incubation at 37° C.A normal PT of 12 s was obtained with Recombiplastin, similar to the values found for the reagents with ISI #2. In the patients on anticoagulants, Recombiplastin gave the longest coagulation times (PTRecombipiastin = 64.2 s vs PTNeoPlastin = 32.8 s, and PTThromborel = 54.4 s). These results suggest that Recombiplastin is highly sensitive to the changes in coagulation induced by anticoagulants. Recombiplastin was more sensitive to factor VII deficiency than any of the other reagents, even those with ISI #1.The coefficients of correlation between the INRS calculated on the basis of the PTS obtained with Recombiplastin and the INRS based on the PTS for other thromboplastins, were satisfactory (0.85 <R <0.95) but a breakpoint in the slope of the regression curves was observed when INR >4. This observation requires further investigation, particularly in connection with the exact ISI values for Recombiplastin and the other thromboplastins used in this study.In conclusion, Recombiplastin is stable and sensitive and gives accurate reproducible results. However, the behavior of Recombiplastin is slightly different from that of the commercial reagents whether their ISI is 1 or 2, and its use did not reduce the interlaboratory dispersion of PT values.

Abstract
BACKGROUND Chronic Kidney Diseases (CKD) of all etiologies are usually associated with Insulin Resistance (IR). Resistin is also a protein associated with IR. Some studies conducted abroad have shown that resistin level is higher among CKD patients. OBJECTIVE To test if serum resistin level is significantly higher in CKD patients compared to normal individuals. PATIENTS AND METHODS 96 CKD patients and 97 normal individuals were included in the study. Written informed consent was obtained from every individual. RESULTS Serum resistin level was higher in CKD patients compared to control subjects. The difference in serum resistin level between two groups was statistically significant. CONCLUSION Our study is probably the first study in India comparing serum resistin levels of CKD patients vis-à-vis control subjects. Further cellular research may be needed to explore this relation.

Abstract
In this study, we aimed to investigate disulfide/thiol homeostasis in trichloroethylene (TCE) exposure. The study was carried out in 30 nonsmoker TCE-exposed workers with a variety of occupations. Additionally, 30 healthy nonsmoker volunteers were recruited as the control group. TCE exposure was determined by measuring urinary trichloroacetic acid (TCA) concentration. Median urinary TCA levels of exposed workers (20.5 mg/L) were significantly higher than control subjects (5 mg/L). Thiol and disulfide concentrations were determined using a novel automated method. Disulfide/thiol ratio was significantly higher in the exposed group ( p < 0.001). Thiol/disulfide homeostasis was found to be disturbed in TCE-exposed workers. We predict that in TCE-exposed workers this disturbance can be a therapeutic target, and the efficiency of the treatment can easily be monitored by the novel method we used.

Abstract
OBJECTIVE Evaluation of utility of fluorine-18 fludeoxyglucose ((18)F-FDG) positron emission tomography/CT (PET/CT) for restaging patients with primary malignant germ cell tumours (GCTs). METHODS Data of 92 patients (age, 31.94 ± 10.1 years; male/female, 86/6) with histopathologically confirmed malignant GCTs (gonadal, 88; mediastinal, 4; seminomatous, 47 and non-seminomatous, 45) who underwent (18)F-FDG PET/CT for restaging (suspected recurrence/post-therapy evaluation) were retrospectively analysed. Two experienced nuclear medicine physicians reviewed the PET/CT images in consensus, qualitatively and semi-quantitatively [maximum standardized uptake value (SUVmax)]. Histopathology (if available) and clinical/imaging/biochemical follow-up (minimum of 6 months) were employed as the reference standard. RESULTS (18)F-FDG PET/CT was interpreted as positive in 59 and negative in 33 patients. Local disease was seen in 5, nodal disease in 50 and distant metastasis in 22 patients. PET/CT was true positive in 49, false positive in 10, true negative in 30 and false negative in 3 patients. (18)F-FDG PET/CT showed sensitivity, specificity, positive predictive value, negative predictive value and accuracy of 94.2%, 75.0%, 83.0%, 90.9% and 85.8% overall; 90.0%, 74.0%, 72.0%, 90.9% and 80.8% in seminomatous GCT; and 96.8%, 76.9%, 91.1%, 90.9% and 91.1% in non-seminomatous GCT, respectively. Difference in PET/CT accuracy for seminomatous and non-seminomatous GCTs was not significant (p = 0.263). PET/CT demonstrated disease in 13 patients with negative/equivocal conventional imaging findings and in 9 patients with normal tumour markers. No site- or histology-based difference was seen in SUVmax. CONCLUSION (18)F-FDG PET/CT demonstrates high diagnostic accuracy for restaging patients with malignant GCTs. It has comparable diagnostic performance in both seminomatous and non-seminomatous malignant GCTs. ADVANCES IN KNOWLEDGE The present article demonstrates high diagnostic accuracy of (18)F-FDG PET/CT for restaging both seminomatous and non-seminomatous malignant GCTs in a large patient population.

Abstract
Primary renal lymphoma (PRL) is a rare disease. We here present the case of an 8-year-old child who presented with bilateral renal masses. On biopsy, it was confirmed to be B-cell non-Hodgkin's lymphoma. (18)F-fluorodeoxyglucose ((18)F-FDG) positron emission tomography-computed tomography (PET/CT) for staging demonstrated (18)F-FDG avid bilateral renal masses, with no other abnormal focus. Follow up (18)F-FDG PET/CT showed complete resolution of the disease after six cycles of chemotherapy. Here we have highlighted the potential role of (18)F-FDG PET/CT in staging and response evaluation of a patient with PRL and presented a brief review.

Abstract
Paragangliomas, or glomus tumors, are neoplasms arising from extra-adrenal chromaffin tissue. They frequently cause symptoms by over-production of catecholamines with known predilection to multicentricity. We describe the case of a patient with bilateral carotid body tumor who underwent a preoperative ⁶⁸Gallium labeled [1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid]-1-NaI3-Octreotide (⁶⁸Ga-DOTANOC) positron emission tomography/computed tomography (PET/CT) imaging for staging. This is a unique case in which multiple paraganglioma and pheochromocytoma were demonstrated in a single patient using ⁶⁸Ga-DOTANOC PET/CT.

Abstract
BACKGROUND Intestinal ischemia-reperfusion injury is a serious and widespread clinical problem. Trolox effectively prevents lipid peroxidation in oxidative stress and protects cell injury. The aim of this study is to investigate the effect of Trolox alone on the intestinal ischemia-reperfusion injury in strangulation ileus model, which has not been investigated previously. METHODS Twenty-eight Sprague-Dawley rats randomly divided into four groups were used. Group Laparotomy + Physiological Saline underwent laparotomy and was administered physiological saline; Group Laparotomy + Trolox was administered Trolox. Group Strangulation + Physiological Saline was administered physiological saline before reperfusion following strangulation ileus; Group Strangulation + Trolox was administered Trolox. RESULTS Histopathological study was evaluated and catalase, malondialdehyde, superoxide dismutase measurements were performed in intestinal samples. Serum biochemistry parameters were evaluated. The higher grade (grade > or = 2) was significantly observed to decrease in Group Strangulation + Trolox when compared with Group Strangulation + Physiological Saline (p = 0.04). In Group Laparotomy + Trolox, when compared with Group Laparotomy + Physiological Saline, the higher grade was found to be significantly lower (p = 0.03). The catalase values were found to be significantly lower in Group Strangulation + Trolox, when compared with Group Strangulation + Physiological Saline, and in Group Laparotomy + Trolox, when compared with Group Laparotomy + Physiological Saline (p < 0.01). CONCLUSIONS Trolox is a powerful antioxidant as well as effectively prevents ischemia-reperfusion injury of the strangulated intestine segment.

Abstract
OBJECTIVE The purpose of the present study was to evaluate the role of 68-gallium-1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid-1-Nal3-octreotide ((68)Ga-DOTA-NOC) positron emission tomography CT (PET-CT) in carotid body chemodectomas (CBCs). METHODS 5 patients with known CBCs (conventional imaging and angiography) were evaluated retrospectively (3 males, 2 females; mean age 36.6 years). All underwent PET-CT after injection of 148 MBq (4 mCi) of (68)Ga-DOTA-NOC. RESULTS At baseline there were four bilateral CBCs and one unilateral CBC with an additional glomus tympanicum and bilateral glomus jugulare tumour in these five patients. All these lesions showed intense uptake on (68)Ga-DOTA-NOC PET-CT. Apart from these known lesions, additional tumours were detected in three patients; glomus jugulare in one, aortic body tumour and multiple abdominal paragangliomas in another and unsuspected vertebral metastasis in the last. Overall it led to a change in management in 3 of the 5 patients (60%). CONCLUSION (68)Ga-DOTA-NOC PET-CT is a promising non-invasive imaging modality in the detection and characterisation of CBCs.

Abstract
BACKGROUND/AIM Posttransplant cardiovascular mortality is still an important problem in renal transplant patients. In addition to conventional coronary risk factors, coagulation abnormalities play a key role in the hypercoagulable state observed in transplanted patients. Though renal transplantation eliminates cardiovascular disease risk factors by restoring renal function, it introduces new cardiovascular risks derived, in part from immunosupressive medications. We aimed to assess the effect of calcineurin inhibitors on endothelial function, platelet activation and aggregation in renal transplant patients. METHODS 62 renal transplant were studied. Staging was performed according to immunosuppression regimen. Group 1 (n = 37) were treated with cyclosporine/mycophenolate mofetil/methylprednisolone and Group 2 (n = 25) were treated with tacrolimus/mycophenolate mofetil/methylprednisolone. The control group consisted of 16 healthy subjects (Group 3). Hematological and biochemical tests, asymmetric dimethyl arginine (ADMA), sP-selectin levels and platelet aggregation tests were studied. RESULTS ADMA levels were higher in Group1 and statistically significant differences were observed compared with those of Group 2 and Group 3 (p < 0.05). Platelet aggregation values induced by all agonists (Adenosine diphosphate (ADP), epinephrine, ristocetin, collagen) were lower in Group 1 than Group 2 and Group 3, but the difference did not reach statistical significance (p > 0.05). There was a negative correlation between cyclosporine level and platelet aggregation values induced by ADP (r = -0.43, p < 0.01), ristocetin (r = -0.40, p < 0.05), epinephrine (r = -0.41, p < 0.05), and collagen (r = -0.43, p < 0.01). sP-selectin levels were appreciably higher in Group 1 and statistically significant differences were observed compared with those of Group 2 (p < 0.05) and Group 3 (p < 0.01). CONCLUSION The results of our study suggest that CsA induces platelet activation without inducing platelet aggregation. Endothelial dysfunction due to vascular endothelial damage reflected by increases in ADMA values may increase the tendency for thrombotic events in patients who had undergone renal transplantation.

Abstract
Oncogenic osteomalacia, or tumour-induced osteomalacia (TIO), is a rare paraneoplastic syndrome characterised by hypophosphataemia, phosphaturia, inappropriately low serum levels of 1,25-dihydroxyvitamin D for hypophosphataemia. TIO is caused by mesenchymal tumours that secrete phosphaturic substances, leading to increased renal wasting of phosphates. These tumours are very small in size and grow slowly. Localisation of these tumours has always been difficult with the available biochemical and imaging techniques. At times, despite all efforts, the tumour could not be localised. We report our experience with a 42-year-old woman with TIO where whole-body magnetic resonance imaging could not localise the tumour, a scapular haemangiopericytoma. PET/CT was helpful in the localisation of the tumour which, when surgically removed, resulted in the normalisation of biochemical parameters with clinical improvement.

Abstract
Health-related quality of life (HRQoL) during therapy was found to be improved in patients treated with peginterferon alpha-2a compared to patients receiving interferon alpha-2a. This study aimed to assess the effect of different pegylated interferon therapies used in the treatment of patients with chronic hepatitis C on HRQoL. Forty chronic hepatitis C patients were enrolled. 22 patients were given a combination of peginterferon alpha-2a plus ribavirin and 18 patients received a combination of peginterferon alpha-2b plus ribavirin for 48 weeks. Patients completed a Short Form-36 (SF-36) questionnaire at the start of treatment and at week 12, week 24 and week 48 of treatment and week 24 posttreatment to evaluate HRQoL. In conclusion, the effect of both combination treatments on quality of life was similar.

Abstract
The aim of this study was to determine the role of colour Doppler imaging in the retrobulbar vascular circulation in diabetic retinopathy (DR). Maximum (V(max)), end-diastolic (V(min)) and average (V(mean)) velocities of blood flows and pulsatility index and resistivity index (RI) in central retinal artery (CRA), short branches of posterior ciliary artery (PCA) and ophthalmic artery of the 65 diabetic and 22 control eyes were measured. The CRA V(max) level in the control group was significantly higher than in DR groups. The CRA V(mean) level was also significantly higher in the control group than in the mild nonproliferative diabetic retinopathy (NPDR) and the moderate NPDR groups. The CRA RI value was significantly higher in the control group than in the nonretinopathy group. The CRA V(min) and the ophthalmic artery RI values were found significantly higher in the nonretinopathy group than in the moderate NPDR group. There were significant decreases in the some CRA and PCA values as glycated haemoglobin (HbA1c) levels increase in diabetic group. There was a positive correlation between the duration of diabetes and HbA1c levels. This study showed the presence of some dynamic circulatory alterations in the nonretinopathy group with diabetes and DR groups. It was also shown that there is a negative correlation between HbA1c and some orbital vascular velocities.

Abstract
AIM Some methylenetetrahydrofolate reductase (MTHFR) gene mutations cause hyperhomocysteinemia and homocystinuria. These may be important risk factors for cardio and cerebrovascular diseases. We investigated whether the MTHFR C677T and A1298C polymorphisms contribute to hyperhomocysteinemia and increase the risk factor for stroke. METHODS A total of 203 acute stroke patients and 55 controls were recruited. Polymorphisms were determined by using polymerase chain reaction-restriction fragment length polymorphism (RFLP) and plasma total homocysteine levels were measured by enzyme-linked immunosorbent assay (ELISA). RESULTS AND CONCLUSIONS There were no significant differences between C677T and A1298C genotypes and allele frequencies in the stroke patients and controls. Total plasma homocysteine level was higher in the 677TT and 1298AA genotypes in stroke patients and especially small-vessel disease patient subgroup. Age, number of males, systolic-diastolic blood pressures, creatinine, vitamin B(12) and homocysteine levels were significantly high among stroke patients. Age, sex, systolic blood pressure and HDL-C were determined as risk factors for homocysteine levels. We also determined that the effect of A1298C polymorphism on homocysteine was not as high as that of C677T polymorphism in acute stroke patients. We conclude that the MTHFR genotype may be a modest risk factor for stroke in Turkish population.

Abstract
PURPOSE To explore the role of single-photon emission CT (SPECT) in initial diagnostic evaluation of patients with mild traumatic brain injury (MTBI) and to identify subgroups in which it may serve as a useful diagnostic tool. MATERIALS AND METHODS Patients with MTBI seen during a 14-month period were prospectively included in this study. All patients had a CT of head within 12 hours of injury and SPECT by using technetium Tc99m ethyl cysteinate dimer (Tc99m-ECD) within 72 hours of injury. Both SPECT and CT findings were compared with clinical features such as posttraumatic amnesia (PTA), postconcussion syndrome (PCS), and loss of consciousness (LOC). RESULTS Ninety-two patients with MTBI underwent SPECT in the study period. There were 28 children and 64 adults, with male-to-female ratio of 4.5 to 1. CT findings were abnormal in 31 (34%) and SPECT in 58 (63%). The most common abnormality was hypoperfusion in the frontal lobe(s) in adults and the temporal lobe in children. A significantly higher number of perfusion abnormalities were seen in patients with PTA (P = .03), LOC (P = .02), and PCS (P = .01) than in patients without these symptoms. Compared to CT, SPECT had a much higher sensitivity for detecting an organic basis in these subgroup, of patients (P < .05). CONCLUSION Tc99m-ECD SPECT can be used as a complementary technique to CT in initial evaluation of patients with MTBI. It is particularly useful in patients having PCS, LOC, or PTA with normal CT scan.

Abstract
BACKGROUND Systemic therapy with radionuclides may be used for the treatment of patients with painful skeletal metastases owing to its efficacy, low cost and low toxicity. Imported radionuclides for pain palliation, like Strontium-89 are expensive; particularly for developing countries. In the Indian scenario, Samarium-153 (Sm-153) is produced in our own reactors and as a result, it is readily available and economical. AIM We undertook this study to determine the efficacy and toxicity of single-dose Sm-153 ethylenediamine tetramethylene phosphonate as a palliative treatment for painful skeletal metastases. MATERIALS AND METHODS Eightysix patients with painful skeletal metastases from various primaries, were treated with Sm-153 EDTMP at a dose of 37 MBq/kg. The effects were evaluated according to change in visual analogue pain score, analgesic consumption, Karnofsky performance score, mobility score and blood count tests, conducted regularly for 16 weeks. STATISTICS Repeated measures analysis. RESULTS The overall response rates were 73%, while complete response was seen in 12.4%. Reduction in analgesic consumption with improvement in Karnofsky performance score and mobility score, was seen in all responders. Response rates were 80.3 and 80.5% in breast and prostate cancer, respectively. One case, each of Wilms tumor, ovarian cancer, germ cell tumor testis, multiple myeloma, primitive neuroectodermal tumor and oesophageal cancer, did not respond to therapy. No serious side-effects were noted, except for fall in white blood cell, platelet and haemoglobin counts, which gradually returned to normal levels by six-eight weeks. CONCLUSION Sm-153 EDTMP provided effective palliation in 73% patients with painful bone metastases: the major toxicity was temporary myelosuppression.

Abstract
To determine independent risk factors associated with the pathogenesis hypoxic hepatitis (HH) in hypoxemic patients. The prospective study, multivariate analysis, between January 1999 and March 2003 was conducted at University hospital, intensive care unit, Department of Chest Diseases. A total of 445 consecutive patients were included in the study. Patients who were not hypoxemic (PaO(2) > 80 mmHg) were excluded from analysis. The total number of those found eligible for the study was 297. Patients with a >20-fold increase in liver enzyme levels were diagnosed as HH (study group). The other patients were defined as control group. There were no interventions. Mean age was 62, and 191 were males. Twenty-two patients were diagnosed as HH (study group; 7.41%). Cor pulmonale (CP) was 77.3% in the study group and 36.7% in the control group. The need for mechanical ventilation and hospital mortality were 63.6 and 54.5% in the study group and 32 and 28.7% in the control group, respectively. On multivariate analysis, the presence of CP (p = 0.007; OR: 4.418; CI: 1.492-13.083), high-serum BUN level (>37 mg/dl; p = 0.0001; OR: 1.029; CI: 1.015-1.044) and low PaO(2) level (<46 mmHg; p = 0.008; OR: 0.945; CI: 0.906-0.985) were found to be significantly different between the two groups. Patients with severe hypoxemia, CP and higher BUN level have higher risk levels for HH, the most important risk factor being CP.

Abstract
Aim of the study was to evaluate the clinical efficacy of sublingual-oral immunotherapy in allergic rhinitis induced by various allergens and to demonstrate its effects using objective methods such as skin prick tests and specific IgE analysis. The first 100 patients diagnosed with allergic rhinitis and treated with sublingual-oral immunotherapy took part in the study and were followed for 2 years. Baseline findings were statistically compared with data obtained at the end of the study period. All symptoms including nasal discharge, sneezing, nasal congestion, and itching, as well as all clinical findings, including lower turbinate colour, turbinate congestion, and nasal discharge, observed by the physician, were significantly decreased after sublingual-oral treatment for two years (p < 0.001). A significant reduction in skin test reactivity was found when the initial and the final tests were compared. The difference between before and after treatment levels of specific IgE levels for D. pteronyssinus, D. farinea, and grasses were significant (p < 0.001), but were not significant for cereals (p=679 ns). As far as concerns the correlation between the recovery of clinical findings and age, as well as the correlation between the recovery of clinical findings and sex, neither of these were statistically significant (age: r = -0.076, p = 0.453, sex: r = -0.004, p = 0.97). The efficacy of the treatment, determined by means of symptom evaluations, was higher than expected in our study. A certain effect of this recovery might be due to the placebo effect, but it is supported by the improvement in skin tests and specific IgE levels.

Abstract
The presence of PER-1- and OXA-10-like beta-lactamases was investigated by PCR in 49 ceftazidime-resistant Pseudomonas aeruginosa isolates from patients hospitalised in the 24-bed general intensive care unit of the Istanbul Faculty of Medicine during a 12-month period between February 1999 and February 2000. The clonal relatedness of the isolates was investigated by random amplified polymorphic DNA (RAPD) analysis, and the sequences of the PER-1 and OXA genes from all isolates were determined. The rates of resistance of the isolates to imipenem, aztreonam and cefepime were 98%, 92% and 96%, respectively, and to piperacillin and piperacillin-tazobactam were 41% and 37%, respectively. Using the double-disk synergy test, 37% (18/49) of the isolates were identified as extended-spectrum beta-lactamase producers. The PER-1 gene was identified in 86% (42/49) and the OXA-10 gene in 55% (27/49) of the ceftazidime-resistant isolates. Of isolates carrying the PER-1 gene, 48% (20/42) also carried the OXA-10 gene. The respective nucleotide sequences were identical for each isolate. Sixteen RAPD patterns were detected among the PER-1-positive isolates, but 60% (25/42) of the PER-1-positive isolates belonged to two distinct patterns, while the remainder exhibited a wide clonal diversity. The results indicated that the prevalence of PER-1- and OXA-10-like beta-lactamases remains high among ceftazidime-resistant P. aeruginosa isolates in Turkey.
