Can catheter-based renal denervation reduce frequency of hospitalization in patients who have resistant hypertension and heart failure with reduced ejection fraction? HIPERTENSION Y RIESGO VASCULAR 2024:S1889-1837(24)00053-9. [PMID: 38641442 DOI: 10.1016/j.hipert.2024.03.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2024] [Revised: 03/22/2024] [Accepted: 03/26/2024] [Indexed: 04/21/2024]
Abstract
Hypertension is one of the most powerful and modifiable risk factors for the development, progression and even decompensation of heart failure. Uncontrolled hypertension increases to frequency of heart failure hospitalizations by increase sympathetic tone. Catheter-based renal denervation has been shown to reduce blood pressure in the treatment of multidrug-resistant hypertension. We report the improvement in clinical status after renal denervation in a 47-year-old male patient with a history of hypertension, chronic ischemic heart failure, and recurrent hospitalizations for acute hypertensive pulmonary edema despite optimal medical therapy.

Adaptation of sea turtles to climate warming: Will phenological responses be sufficient to counteract changes in reproductive output? GLOBAL CHANGE BIOLOGY 2024; 30:e16991. [PMID: 37905464 DOI: 10.1111/gcb.16991] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/20/2023] [Revised: 10/02/2023] [Accepted: 10/03/2023] [Indexed: 11/02/2023]
Abstract
Sea turtles are vulnerable to climate change since their reproductive output is influenced by incubating temperatures, with warmer temperatures causing lower hatching success and increased feminization of embryos. Their ability to cope with projected increases in ambient temperatures will depend on their capacity to adapt to shifts in climatic regimes. Here, we assessed the extent to which phenological shifts could mitigate impacts from increases in ambient temperatures (from 1.5 to 3°C in air temperatures and from 1.4 to 2.3°C in sea surface temperatures by 2100 at our sites) on four species of sea turtles, under a "middle of the road" scenario (SSP2-4.5). Sand temperatures at sea turtle nesting sites are projected to increase from 0.58 to 4.17°C by 2100 and expected shifts in nesting of 26-43 days earlier will not be sufficient to maintain current incubation temperatures at 7 (29%) of our sites, hatching success rates at 10 (42%) of our sites, with current trends in hatchling sex ratio being able to be maintained at half of the sites. We also calculated the phenological shifts that would be required (both backward for an earlier shift in nesting and forward for a later shift) to keep up with present-day incubation temperatures, hatching success rates, and sex ratios. The required shifts backward in nesting for incubation temperatures ranged from -20 to -191 days, whereas the required shifts forward ranged from +54 to +180 days. However, for half of the sites, no matter the shift the median incubation temperature will always be warmer than the 75th percentile of current ranges. Given that phenological shifts will not be able to ameliorate predicted changes in temperature, hatching success and sex ratio at most sites, turtles may need to use other adaptive responses and/or there is the need to enhance sea turtle resilience to climate warming.

Abstract
OBJECTIVE To investigate whether adding docetaxel chemotherapy to androgen deprivation therapy is effective regarding progression-free and overall survival in patients with de novo metastatic castration-sensitive prostate cancer patients with Gleason Grade Group 5 (Gleason scores 9 and 10). STUDY DESIGN Observational study. Place and Duration of the Study: Department of Medical Oncology at Manisa Celal Bayar University, Izmir Ege University, Bitlis Tatvan Public Hospital, Izmir Bozyaka Education and Research Hospital, and Izmir Kent Hospital, from March 2015 to May 2020. METHODOLOGY Patients with de novo metastatic castration-sensitive and histopathologically confirmed GGG 5 prostate cancer were evaluated retrospectively. The patients were divided into two groups. The first group included patients who were given androgen deprivation therapy alone (ADT-only group), and the second group consisted of patients who were given ADT plus docetaxel (chemohormonal group). The two groups were compared in terms of overall survival and progression-free survival till cut-off limit. RESULTS A total of 194 patients with metastatic castration-sensitive and GGG 5 prostate cancer were analysed retrospectively. The chemohormonal group comprised of 72 patients, and the ADT-only group included 122 patients. Median progression-free survival was 15.7 months in the chemohormonal group and 14.8 months in the ADT-only group (p = 0.97). The median overall survival was 37.5 months in the chemohormonal group and 37.8 months in the ADT-only group (p = 0.93). CONCLUSION The addition of docetaxel chemotherapy in patients with metastatic castration-sensitive and GGG 5 prostate cancer did not result in a statistically significant difference in terms of overall survival and progression-free survival. Docetaxel may be ineffective in this group of patients. KEY WORDS Prostate cancer, Castration-sensitive, Gleason grade group 5, Docetaxel, Androgen deprivation therapy (ADT), Overall survival.

Abstract
In our study, we aimed to evaluate the pathological response rates and side effect profile of adding pertuzumab to the treatment of HER2+ locally advanced, inflammatory, or early-stage breast cancer. This study was conducted by the Turkish Oncology Group (TOG) with data collected from 32 centers. Our study was multicentric, and a total of 364 patients were included. The median age of the patients was 49 years (18-85 years). Two hundred fifteen (60%) of the cases were hormone receptor/HER2+ positive(ER+ or PR+, or both), and 149 (40%) of them were HER2-rich (ER and PR negative). The number of complete responses was 124 (54%) in the docetaxel+trastuzumab+pertuzumab arm and 102 (45%) in the paclitaxel+trastuzumab+pertuzumab arm, and there was no difference between the groups in terms of complete response. In 226 (62%) patients with complete response, a significant correlation was found with DCIS, tumor focality, removed lymph node, and ER status P < 0.05. Anemia, nausea, vomiting, myalgia, alopecia, and mucosal inflammation were significantly higher in the docetaxel arm, P < 0.05. In our study, no statistical difference was found between the before-after echocardiography values. DCIS positivity in biopsy before neoadjuvant chemotherapy, tumor focality; the number of lymph nodes removed and ER status were found to be associated with pCR. In conclusion, we think that studies evaluating pCR-related clinicopathological variables and radiological imaging features will play a critical role in the development of nonsurgical treatment approaches.

GLASS: Global Lorlatinib for ALK(+) and ROS1(+) retrospective Study: real world data of 123 NSCLC patients. Lung Cancer 2020; 148:48-54. [PMID: 32799090 DOI: 10.1016/j.lungcan.2020.07.022] [Citation(s) in RCA: 19] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2020] [Revised: 07/08/2020] [Accepted: 07/16/2020] [Indexed: 12/15/2022]
Abstract
Lorlatinib is a third-generation tyrosine-kinases inhibitor (TKI) targeting ALK/ROS1 fusions. The FDA has approved lorlatinib for TKI-pretreated ALK(+) NSCLC, while its approval for ROS1(+) is still pending. Here we present the largest real-world data of NSCLC patients harboring ALK/ROS1 rearrangements treated with lorlatinib. METHODS 123 patients were enrolled retrospectively (data cut-off 1/1/2019). Lorlatinib was administered through an early access program for patients with no other available therapy. Outcome and response were defined by each investigator upon RECIST 1.1 criteria. RESULTS 106 ALK(+) and 17 ROS1(+) patients recruited from 8 different countries. The ALK(+) cohort included 50 % males, 73 % never-smokers and 68 % with brain metastases. Extracranial (EC) and intracranial (IC) response rates (RR) were 60 % and 62 %, with disease control rates (DCR) of 91 % and 88 % respectively. Mean duration of therapy (DoT) was 23.9 ± 1.6 months and median overall survival (mOS) was 89.1 ± 19.6 months. ROS1 cohort enrolled 53 % males, 65 % never-smokers and 65 % had brain metastases. EC and IC RR were 62 % and 67 % with DCR of 92 % and 78 % respectively. Median DoT was 18.1 ± 2.5 months and mOS of 90.3 ± 24.4 months. OS and DoT in both cohorts were not significantly correlated with line of therapy nor other parameters. The most common adverse events of any grade were peripheral edema (48 %), hyperlipidemia (47 %), weight gain (25 %) and fatigue (30 %). CNS adverse events such as cognitive effect of grade 1-2 were reported in 18 % of patients. CONCLUSION Lorlatinib shows outstanding EC/IC efficacy in ALK/ROS1(+) NSCLC. The observed mOS of 89 ± 19 months in ALK(+) NSCLC supports previous reports, while mOS from of 90 ± 24 months is unprecedented for ROS1(+) NSCLC.

Abstract
OBJECTIVE Polycystic ovary syndrome (PCOS) is a common endocrine disorder in women of reproductive age. The renal resistive index (RRI) is a measure of renal arterial resistance to blood flow. The aim of this study was to investigate the renal resistive index levels of patients with PCOS. SUBJECTS AND METHODS A total of 216 women were included in this cross-sectional study. The study group consisted of 109 patients with PCOS, and the control group consisted of 107 healthy subjects. The RRI of all subjects was measured using renal Doppler ultrasonography. RESULTS The patients with PCOS had higher RRI levels in comparison to the healthy subjects (0.64 ± 0.06 vs. 0.57 ± 0.06, p < 0.001). The RRI levels of the patients with PCOS were correlated with systolic blood pressure (p = 0.004, r = 0.268) and with homeostasis model assessment of insulin resistance (HOMA-IR) (p = 0.02, r = 0.216). CONCLUSION In this study, we observed higher RRI levels in patients with PCOS. High RRI levels may be an indicator of cardiovascular and/or cardiovascular-associated diseases in patients with PCOS.

Abstract
PURPOSE In this study we aimed to compare and evaluate the efficacies of the low and high b value diffusion weighted imaging (DWI) sequences with three different T2-weighted (T2W) sequences. MATERIALS AND METHODS 255 liver lesions of 147 patients who had undergone MR examinations of the upper abdomen were evaluated. A maximum number of 4 lesions was taken for consideration in patients with multiple lesions. Low and high b valued DWI and 3 different T2W sequences (SSFSE, FIESTA, and PROPELLER FSE) were utilized. The evaluations were done by 3 different radiologists, by utilizing the double blind principle. RESULTS The lesion detection performances of the b 0 DWI, b 600 DWI, FIESTA T2W, SSFSE T2W, and PROPELLER FSE T2W sequences, were 95.7 %, 66.3 %, 94.4 %, 92.8 %, and 93.8 %, in sequence order. The high b value DWI sequence was able to detect malignant lesions with a higher accuracy rate than the T2W sequences. There was a moderate to high rate of agreement among the interpreters, and the lesion-detection rates of the interpreters were in line with their levels of expertise. CONCLUSION Even though the higher lesion detection rates of the DWI sequences were not found to be statistically significant, it was concluded that making the evaluations with the addition of DWI to the imaging protocol would certainly decrease the lesion-missing rate, and it would be wise to utilize the DWI technique in routine liver MR imaging.

Abstract
OBJECTIVE This study aimed to analyze the effect of human Dental Pulp-Neural Crest Stem Cells (hDP-NCSCs) delivery on lesion site after spinal cord injury (SCI), and to observe the functional recovery after transplantation. METHODS Neural Crest Stem Cells (NCSCs) were isolated from human Dental Pulp (hDP). The experimental rat population was divided into four groups (n = 6/24). Their behavioral motility was scored regularly. After 4-weeks, rats were sacrificed, and their spinal cords were examined for Green Fluorescent Protein (GFP) labeled hDP-NCSCs by immunofluorescence (IF) staining. RESULTS In early post-injury (p.i) period, the ultrastructure of spinal cord tissue was preserved in Group 4. The majority of cells forming the ependymal region around the central canal were found to be hDP-NCSCs. While the grey-and-white-matter around the ependymal region was composed of e.g. GFP cells, with astrocytic-like appearance. The scores showed significant motor recovery in hind limb functions in Group 4. However, no obvious change was observed in other groups. CONCLUSION Cells e.g., mesenchymal (Vimentin+) which express GFP+ cells in the gray-and-white-matter around the ependymal region could indicate the potential to self-renewal and plasticity. Thus, transplantation of hDP-NCSCs might be an effective strategy to improve functional recovery following spinal cord trauma (Fig. 10, Ref. 32).

Abstract
INTRODUCTION Liver transplantation (LT) remains the best treatment option for hepatocellular carcinoma (HCC). Patient selection is crucial and debated ever since the emerging of the Milan criteria in 1996. As live-donor LT is being more routinely performed worldwide, numerous new and/or expansions of the original criteria have been suggested to allow more patients to benefit from this superior treatment modality. This study aims to contribute to the ever-growing data in search for better coverage of patients with acceptable outcomes. METHODS Medical recordings of 187 adult patients who underwent LT for HCC in a 6-year period were retrospectively collected. Patients were classified by Milan and University of California, San Francisco, criteria. Survival times as well as tumor, liver disease, and recurrence-related data were recorded for each patient and the outcomes were statistically analyzed. RESULTS Factors significantly affecting recurrence and survival were histologic differentiation, number and the size of the tumor, and the presence of vascular invasion. Serum alpha-fetoprotein levels did not significantly affect outcomes. Among the patients exceeding both of the criteria, having a total tumor size of less than 160 mm was significantly associated with better outcomes (P = .007). CONCLUSION HCC patients having tumors with vascular invasion, poor differentiation, exceeding 6 in number and 160 mm in total diameter demonstrate higher recurrence rates and worse outcomes.

Abstract
Background Biologic treatment options for cartilage injuries require chondrocyte expansion using cell culture. Clinical application is accomplished in two surgical sessions and is expensive. If isolation of chondrocytes and stimulus for proliferation and extracellular matrix synthesis can be achieved in vivo, the treatment can be performed in one session and the cost can be reduced. Methods A 2.5-cm diameter full-thickness chondral defect was created in the knees of five groups of sheep. In one group, some of the chondral tissues obtained from the creation of the defect were diced into small pieces and were placed into the defect and were covered with a collagen membrane (MIV group). In the other group, the collagen membrane was soaked in collagenase prior to usage. In the next group, the collagen membrane was soaked in both collagenase and growth factors. Matrix-induced autologous chondrocyte implantation (MACI) was applied to another group in two sessions, and the last group was left untreated. After 15 weeks of follow-up, repair tissues were compared macroscopically, histomorphometrically, and biochemically for tissue concentrations of glycosaminoglycan and type II collagen. Results MACI and MIV groups demonstrated better healing than others and were similar. Addition of collagenase or growth factors did not improve the results. Addition of collagenase did not have detrimental effect on the surrounding cartilage. Conclusions With the described method, it is possible to obtain comparable results with MACI. Further studies are also needed to see if it works similarly in humans.

Abstract
BACKGROUND Venous reconstruction in living-donor liver transplantation for Budd-Chiari syndrome (BCS) has challenges because the grafts from living donors lack vena cava, and hepatic venous anastomosis must be performed on an already-thrombosed and/or stenosed inferior vena cava. Several techniques are described to overcome this problem, and we represent our experience with 22 patients. METHODS Medical recordings of 22 patients were retrospectively collected, and disease-specific data as well as recordings about surgical technique were analyzed. RESULTS Creation of a wide, triangular de novo orifice was the main method used for venous drainage, which was used in 19 patients. The remaining 3 patients had totally thrombosed vena cava; thus, direct anastomosis to the supra-hepatic portion of the vena cava was used in 2 patients and an anastomosis to the right atrium was used in 1 patient. CONCLUSIONS Venous reconstruction in BCS can be achieved without the use of patch-plasty, and the inferior vena cava can be safely resected in selected patients. Living-donor liver transplantation is a feasible option for the treatment of BCS, considering the scarcity of cavaderic donors.

Abstract
PURPOSE Gossypol, a naturally occurring compound in cottonseeds, has anticancer effects against several tumor cell lines. It has been extensively studied in clinical trials and is well tolerated with a favorable safety profile. AT-101, a derivative of R (-)-gossypol, binds to Bcl-2 family proteins and induces apoptosis in vitro. Although transsphenoidal surgical excision of the pituitary corticotroph adenoma is the gold standard of care, it is not successful all the time. Medical therapy for Cushing's disease still remains a challenge for the clinicians. We aimed to investigate the cytotoxic and apoptotic effects of AT-101 in mouse pituitary corticotroph tumor AtT20 cells. METHODS Cytotoxic effect of AT-101 was assessed by XTT cell viability assay. Apoptosis was shown by measuring DNA fragmentation and Caspase-3/7 activity. Changes in mRNA expressions of apoptosis-related genes were investigated by qPCR array after treatment with AT-101. ACTH was measured by ACTH-EIA Kit. RESULTS AT-101 induced cytotoxicity and apoptosis in AtT20 cells. mRNA levels of pro-apoptotic genes such as TNFR-SF-10B, Bid, PYCARD, Caspase-8, Caspase-3, and Caspase-7 were induced by 2.0-, 1.5-, 1.7-, 1.5-, 1.6-, and 2-fold, respectively, in AtT20 cells by AT-101 treatment. Moreover, some of the anti-apoptotic genes such as BCL2L10, NAIP1, and PAK-7 were reduced by 2.1-, 2.3-, 4.0-fold, respectively, in AtT20 cells. AT-101 also decreased ACTH secretion significantly. CONCLUSION AT-101 induces apoptosis in mouse pituitary corticotroph tumor cells.

Abstract
INTRODUCTION Drug induced acute toxic hepatitis can be idiosyncratic. Albendazole, a widely used broad spectrum antiparasitic drug is generally accepted as a safe drug. It may cause asymptomatic transient liver enzyme abnormalities but acute toxic hepatitis is very rare. Case Report : Herein, we present the case of 47 year old woman with recurrent acute toxic hepatitis after a single intake of albendazole in 2010 and 2014. The patient was presented with symptoms and findings of anorexia, vomiting and jaundice. For diagnosis, other acute hepatitis etiologies were excluded. Roussel Uclaf Causality Assessment Method (RUCAM) score was calculated and found to be 10, which meant highly probable drug hepatotoxicity. Within 2 months, all pathological findings came to normal. RESULT There are a few reported cases of albendazole induced toxic hepatitis, but at adults, there is no known recurrent acute toxic hepatitis due to albendazole at this certainty according to RUCAM score. CONCLUSION Physicians should be aware of this rare and potentially fatal adverse effect of albendazole.

Abstract
Pulmonary agenesis is a rarely encountered congenital anomaly, and its average prevalence is about 1 in 100,000 births. Anomalies of the cardiovascular, musculoskeletal, gastrointestinal, or genitourinary systems may accompany in nearly half of the cases. The diagnosis of pulmonary agenesis is usually made during childhood, but the diagnosis may be delayed until adulthood in case of an absence of comorbid anomalies . Herein, we present a case of pulmonary agenesis that was diagnosed during adulthood.

Abstract
AIM Obese diabetic (ZDF fa/fa) rats with genetic leptin resistance suffer chronic lipotoxicity associated with age-related lung restriction and abnormal alveolar ultrastructure. We hypothesized that these abnormalities impair adaptation to ambient hypoxia. METHODS Male fa/fa and lean (+/+) ZDF rats (4-months old) were exposed to 21 or 13% O2 for 3 weeks. Lung function was measured under anaesthesia. Lung tissue was assayed for DNA damage and ultrastructure measured by morphometry. RESULTS In normoxia, lung volume, compliance and diffusing capacity were lower, while blood flow was higher in fa/fa than +/+ rats. In hypoxia, fa/fa animals lost more weight, circulating hematocrit rose higher, and lung volume failed to increase compared to +/+. In fa/fa, the hypoxia-induced increase in post-mortem lung volume was attenuated (19%) vs. +/+ (39%). Alveolar ducts were 35% smaller in normoxia but enlarged twofold more in hypoxia compared to +/+. Hypoxia induced broad increases (90-100%) in the volumes and surface areas of alveolar septal components in +/+ lungs; these increases were moderately attenuated in fa/fa lungs (58-75%), especially that of type II epithelium volume (16 vs. 61% in +/+). In fa/fa compared to +/+ lungs, oxidative DNA damage was greater with increased hypoxia induced efflux of alveolar macrophages. Harmonic mean thickness of the diffusion barrier was higher, indicating higher structural resistance to gas transfer. CONCLUSION Chronic lipotoxicity impaired hypoxia-induced lung expansion and compensatory alveolar growth with disproportionate effect on resident alveolar progenitor cells. The moderate structural impairment was offset by physiological adaptation primarily via a higher hematocrit.

Abstract
Context: Distant metastases of primary malignancies to the skeletal muscle tissue are a very rare event. Distant metastases that affect the rotator cuff are even rarer, and only a few of cases have been reported so far. Case Report: The present article reports two cases that presented to our hospital with the complaint of shoulder pain and had a soft tissue mass affecting the muscles of the rotator cuff and invading the neighboring bone compartments. One of the patients developed mucoepidermoid cancer metastasis of the submandibular gland, and the other was found to have a malignant epithelial tumor metastasized from the lower lobe of the right lung, whose primary origin could not be diagnosed until the imaging examinations were employed. Ultrasound and magnetic resonance imaging findings are presented in this paper. Conclusion: Metastases to the muscle tissues could be misdiagnosed as primary sarcomas. Because the therapy regiments and prognoses are fairly different for these two entities, the possibility of a metastasis to the muscle tissue must be considered as a differential diagnosis for case of painful soft tissue mass. Ultrasound is very useful in detection of the lesion and acts as a very important tool during guidance for biopsy. Magnetic resonance imaging, however, is a very valuable asset in the evaluation of the borders of the soft tissue mass and its invasive effect on the bony tissues. Particularly when the features such as lobulated contours, peripheral edema, and intratumoral necrosis exist, the possibility of metastases must be considered.

Abstract
Brain stem is the most vital part of our body and is a transitional region of the brain that connects the cerebrum with the spinal cord. Though, being small in size, it is full of indispensible functions such as the breathing, heart beat. Injury to the brain stem has similar effects as a brain injury, but it is more fatal. Use of the Glasgow Coma Score as a prognostic indicator of outcome in patients with head injuries is widely accepted in clinical practice. Traumatic brain stem edema in children is rare, but is associated with poor outcome. The question is that whether it is being aware of computerized tomography appearance of the posterior fossa when initial evaluating pediatric patients with head trauma at emergency clinics. Normal and edematous brain stem without an additional pathology are slightly different and not distinguished easily. On the other hand, brain stem edema should be promptly identified and appropriately treated in a short time.

Abstract
UNLABELLED Clinical trials have shown that zoledronic acid was more effective than other bisphosphonates in the treatment of Paget disease. We retrospectively reviewed remission and relapse statuses of 12 patients with Paget disease. Remission was achieved in all patients after treatment. We recommend zoledronic acid in the first-line treatment of Paget disease. INTRODUCTION Paget disease is a disease of bone of unknown etiology with increased bone turnover that results in defective bone microarchitecture and bone deformity. Bisphosphonates are used in symptomatic Paget disease of bone. Clinical trials have shown that zoledronic acid was more effective than other bisphosphonates in the treatment of Paget disease. METHODS In this study, we retrospectively reviewed the remission and relapse statuses of 12 patients with Paget disease of bone who were seen as outpatients between October 2011 and October 2013.We evaluated alkaline phosphates, osteocalcin, and deoxypyridinoline levels measured before and at 6th, 12th, and 18th months of treatment. RESULTS Pretreatment and posttreatment values for alkaline phosphates, deoxypyridinoline, and osteocalcin were as follows: 473 ± 256 U/L, 14.99 ± 7.63 mmol/L, 21.09 ± 3.18 ng/ml, and 82 ± 13 U/L, 5.14 ± 1.11 mmol/L, and 8.57 ± 4.31 ng/ml. Remission was achieved in all patients after treatment. The levels indicated that remission continued at 12th and 18th months of treatment. There was statistically significant difference between pretreatment and posttreatment values. No statistically significant difference between the levels measured at 6th, 12th, and 18th months of treatment was detected. CONCLUSION We recommend zoledronic acid in the first-line treatment of Paget disease of bone in achieving and maintaining remission.

Abstract
BACKGROUND Intragastric band migration is an unusual but major complication of gastric banding. We review our experience with endoscopic removal of eroded gastric bands. METHODS We retrospectively evaluated the cases of 110 morbidly obese patients who underwent adjustable gastric banding between 2005 and 2012 to identify those who experienced band erosion. To remove the migrated band, we used an endoscopic approach with a Gastric Band Cutter. RESULTS Band or tube erosion occurred in 14 patients (12.7%). The median time interval from the initial gastric band placement to the diagnosis of band erosion was 32 (range 18-52) months. Upper abdominal pain, port site infection, loss of restriction and weight regain were the most common symptoms. We used the Gastric Band Cutter to remove the band endoscopically. It was able to cut the band successfully in all but 1 patient, in whom twisting of the cutting wire required conversion from endoscopy to laparotomy. In 2 patients, the band, after being cut, was locked in the gastric wall and required laparotomic removal. In 1 patient, we performed surgery for intragastric penetration of the connecting tube broken close to the band. CONCLUSION The Gastric Band Cutter was successful in dividing the band in all but 1 patient, although we could not always complete the procedure endoscopically. Endoscopic removal seems to be effective and safe for band erosion.

Abstract
AIM Hypocalcaemia evaluation of the clinical, biochemical and radiologicalfeatures of 91 infants with rickets who presented as hypocalcaemic convulsions. SUBJECTS AND METHODS Ninety-one hypocalcaemic infants who were brought to hospital with convulsion and diag-nosed with rickets related to vitamin D deficiency according to their clinical, biochemical and radio-logicalfeatures were retrospectively reviewed. RESULTS Mean values of the laboratory data were as follows: calcium 5.55 +/- 0.79 mg/dL, phosphorus 4.77 +/- 1.66 mg/dL, alkaline phosphatase 1525.5 +/- 925.4 U/L and parathormone 256.8 +/- 158.3 pg/mL. Serum 25-OH vitamin D levels were below normal (< 20 ng/mL) in 37 infants. CONCLUSION Vitamin D deficiency should be considered in infants presenting with hypocalcaemia. To avoid complications such as convulsions, clinicians should give vitamin D supplementation to such infants.

Abstract
BACKGROUND Implant-related infections with bacteria resistant to multiple antibiotics represent one of the major problems in orthopaedic surgery. It was our hypothesis that local application of bacteriophages, which are bacteria-destroying viruses, would be effective against biofilm-forming bacteria. METHODS An implant-related infection model was created using methicillin-resistant Staphylococcus aureus (MRSA) in forty-eight rats and Pseudomonas aeruginosa in another forty-eight rats. Each group was divided into four subgroups; one subgroup received a bacterium-specific bacteriophage (Sb-1 in the MRSA group and PAT14 in the Pseudomonas aeruginosa group), one received antibiotic for fourteen days (20 mg/kg/day teicoplanin in the MRSA group, and 120 mg/kg/day imipenem + cilastatin and 25 mg/kg/day amikacin in the Pseudomonas group), one received antibiotic and bacteriophage, and one received no treatment. Animals receiving bacteriophage therapy were injected locally with 107 bacteriophages in a 0.1-mL suspension on three consecutive days. All animals were killed on the fifteenth day after initiation of treatment, and the tibia was excised. Results were assessed with use of microbiology, light microscopy, and electron microscopy. RESULTS In the MRSA group, the antibiotic administration significantly decreased the number of colony-forming units per subject in quantitative cultures (control subgroup, 50,586; bacteriophage, 30,788; antibiotic, 17,165; antibiotic + bacteriophage, 5000; p = 0.004 for the comparison of the latter group with the control). Biofilm was absent only in the antibiotic + bacteriophage subgroup. In the Pseudomonas group, the number of colony-forming units per subject in quantitative cultures was significantly lower in each treatment subgroup compared with the control subgroup (control subgroup, 14,749; bacteriophage, 6484 [p = 0.016]; antibiotic, 2619 [p = 0.01]; antibiotic + bacteriophage, 1705 [p < 0.001]). The value in the antibiotic + bacteriophage subgroup was also significantly lower than the values in the other subgroups (p = 0.006). Biofilm thickness did not differ significantly among the subgroups in the Pseudomonas group. CONCLUSIONS The addition of bacteriophage treatment to an appropriate antibiotic regimen helped to dissolve the biofilm of both types of bacteria studied. This effect on MRSA was more pronounced than that on Pseudomonas aeruginosa.

Abstract
AIM Oxidative stress has been implicated as a potential responsible mechanism in the pathogenesis of vancomycin (VCM)-induced renal toxicity. Therefore, we aimed to investigate the protective effect of thymoquinone (TQ) against VCM-induced nephrotoxicity by tissue oxidant/antioxidant parameters and histological changes in rats. MATERIALS AND METHODS Wistar albino rats were randomly separated into four groups consisting of seven rats per group. The groups had normal saline (control group), VCM, VCM and TQ and TQ, respectively. VCM was injected intraperitoneally at a dose of 200 mg/kg and continued at 12-h intervals for 7 days. TQ was injected intraperitoneally at a dose of 10 mg/kg and continued at 24 h intervals for 8 days. Animals were killed and blood samples were analyzed for the levels of serum blood urea nitrogen (BUN) and creatinine (Cr). Kidney specimens were analyzed for levels of malondialdehyde (MDA) and activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) as well as for histopathological changes. RESULTS We found that the levels of serum BUN, Cr and kidney tissue MDA were increased in the VCM group. Activities of SOD and GSH-Px in kidney tissue were decreased. TQ administration ameliorated significantly these changes. CONCLUSION These results indicate that the TQ produces a protective mechanism against VCM-induced nephrotoxicity and suggest a role of oxidative stress in pathogenesis.

Anterior cruciate ligament reconstruction improves the metabolic energy cost of level walking at customary speeds. Knee Surg Sports Traumatol Arthrosc 2011; 19:1271-6.

Abstract
PURPOSE The metabolic energy cost of walking is altered by pathological changes in gait. It is thought that anterior cruciate ligament (ACL) deficiency alters the energy requirement for level walking through its effect on gait pattern. In this study, it is hypothesised that the metabolic energy cost of walking would improve after ACL reconstruction. METHODS Eight patients who were undergoing ACL reconstruction for an isolated rupture were included in this prospective study. Clinical examinations, Lysholm scores and metabolic tests were performed preoperatively and at 3, 6 and 12 months after ACL reconstruction using autologous quadruple hamstring tendons. For the metabolic evaluation, net oxygen cost was calculated while walking on a treadmill at 50-, 70- and 90-m/min velocities. A two-way factorial ANOVA was performed in order to evaluate the primary effects and interactions of the time point and velocity variables on net oxygen cost. RESULTS All patients had positive Lachman and anterior drawer tests preoperatively that became negative postoperatively and remained negative until the last follow-up point. The mean preoperative Lysholm score was 66, whereas the mean postoperative follow-up scores were 85, 91 and 94, respectively. The interaction between follow-up time point and velocity was not significant. Regardless of the selected velocity, the net oxygen cost was lower than that at preoperative levels at each postoperative time point (p < 0.05). CONCLUSION The results of the present study indicate that the energy cost of level walking in chronic ACL-deficient patients improves after ACL reconstruction. Cause-effect-based studies with correlation evaluations that compare kinetic, kinematic and electromyographic data and metabolic cost calculations should facilitate more accurate analyses. LEVEL OF EVIDENCE Therapeutic study, Level 4.

Abstract
To investigate the influence of two insulin administration modalities, continuous subcutaneous insulin infusion (CSII) and multiple daily insulin injections (MDI) therapy with insulin analogues, on the development of insulin antibodies (IAs) in patients with type 1 diabetes mellitus and to assess the impact of IAs on glucose control and hypoglycaemia. 96 patients with type 1 diabetes mellitus treated with CSII (n = 48) or MDI (n = 48) were included in the study. Age, duration of diabetes, A1c, preprandial and postprandial blood glucose and hypoglycaemic events were compared between IA positive and negative patients. IA levels were higher in the CSII group (% 24.6 ± 14.2) than the MDI group (% 13.2 ± 9.9). Duration of diabetes and age were not associated with IA positiveness. While A1c, preprandial blood glucose and the frequency of hypoglycaemic events were similar in two groups, postprandial blood glucose was lower in IA positive group (P = 0.03). Patients with type 1 diabetes mellitus treated with CSII with insulin analogues had higher IA levels when compared to MDI therapy. However, the development of IAs did not impair the glycaemic control.

Abstract
Adrenocorticotropin (ACTH) producing macroadenomas and pituitary apoplexy are unusual in Cushing' s disease. A 20-year-old man who had been diagnosed Cushing' s disease 2 months ago, presented with sudden headache, nausea, and vomiting. His serum cortisol level was 0.4 μg/dl and ACTH level was 23.9 pg/ml. Magnetic resonance imaging of the pituitary gland disclosed a hemorrhage in the pituitary macroadenoma (22×19 mm). He was treated with IV methylprednisolone immediately and then the symptoms were relieved within the first day of the treatment. The hemorrhagic lesion was resected by transsphenoidal surgery successfully. Impaired secretion of pituitary hormones may be seen after the pituitary apoplexy. We communicate a case with pituitary apoplexy of an ACTH secreting pituitary macroadenoma, causing acute glucocorticoid insufficiency.

Abstract
OBJECTIVES Axillary and forearm crutches are commonly utilized in the treatment of foot and ankle injuries. In order to decrease the energy expenditure during mobilization, to prevent upper extremity complications, and to let the upper extremity free for other usages, we designed a new orthosis. The study is conducted to compare walking energy parameters of this newly designed orthosis with the axillary and forearm crutches. MATERIALS AND METHODS 10 healthy young male volunteers walked on treadmill with three different orthoses in randomized order. Oxygen expenditure, oxygen cost, rate of perceived exertion (Borg scale), and observer stability assessment were analyzed. RESULTS Concerning oxygen consumption, perceived exertion, and observer stability assessment, the new device was found superior to the other devices (P<0.05). The new orthosis was superior to forearm crutches concerning oxygen cost (P=0.027) but not significantly different from the axillary crutches (P=0.062). DISCUSSION Compared to frequently used orthoses, the developed device provides mobilization using less or similar amount of energy. Additionally it spares one upper extremity to be used for other activities.

Abstract
Plasma TAFI may participate in arterial thrombosis in cardiovascular diseases (CVD) and may be involved in the mechanism of vascular endothelial damage in diabetic patients. The aim of this study was to investigate the association of plasma TAFI antigen level in the development of diabetic foot ulcer in Type 2 diabetes. The TAFI antigen levels were determined in 50 patients with diabetic foot ulcers and 34 patients without diabetic foot ulcers and 25 healthy individuals. We measured TAFIa/ai antigen in plasma samples with a commercially available ELISA Kit. Diabetic foot ulcer group and diabetic group were similar in terms of mean age and sex distribution. Diabetes duration, retinopathy, neuropathy, macrovascular disease and infection were related to diabetic foot ulcers. HbA1c, HDL-cholesterol and Folic Acid levels were decreased in the diabetic foot ulcer group. TAFI levels were 99.44 ± 55.94% in control group, 135.21 ± 61.05% in diabetic foot ulcer group, 136.75 ± 59.38% in diabetic group and was statistically different (P < 0.05). But no difference was seen in TAFI levels between the diabetic foot ulcer group and diabetic group (P > 0.05). No significant difference in plasma TAFI levels were seen between diabetic foot ulcer stages. TAFI antigen levels are increased in Type 2 diabetic patients, but are not related to diabetic foot ulcer development.

Abstract
OBJECTIVE The aims of the study were to compare: a) the thermogenic responses in subclinical hypothyroidism (SH) and euthyroid state; b) the relationship between thermogenic response and leptin level. METHODS Thirty women diagnosed with SH (mean age 39.9+/-4.1 yr; body mass index 23.2+/-2.5 kg/m(2)) were enrolled in the study. Thyroid function tests, leptin, and lipid profiles were measured during SH and after stable euthyroidism was recovered. Thermogenic response was measured by Water Immersion Calorimetry during SH and after the euthyroid state was attained. RESULTS The mean level of thermogenic response was found to be 1.45+/-0.43 kcal/kg*h in women with SH. It changed to 1.54+/-0.77 kcal/kg*h (p=0.01) in the euthyroid state; the change was statistically significant. Mean level of leptin was found to be 7.22+/-2.6 ng/ml in SH; and 15.8+/-8.0 ng/ml in the euthyroid state. There was a positive correlation between leptin and free T(3) (r=0.460, p=0.009) levels in SH. There were positive correlations between leptin level and fat mass in SH (r=0.820, p=0.01) and in the euthyroid state (r=0.700, p=0.03). CONCLUSIONS No correlations were found between thermogenic response and leptin levels in SH and in the euthyroid state. Thermogenic response and leptin levels rose after the euthyroid state was recovered.

Abstract
AIM The therapeutic effect of sildenafil citrate on cerebral vasospasm after experimental subarachnoid hemorrhage (SAH) was studied in a rat model. METHODS We used four groups of seven rats were as follows: no SAH, no treatment; SAH only; SAH plus 2 days of peroral sildenafil citrate 5mg/kg treatment and SAH plus 2 days of peroral sildenafil citrate 15 mg/kg treatment. Three different parameters were evaluated including the diameter of the basilar artery, the level of lipid peroxidation and the degree of the apoptosis 48 hours following SAH. RESULTS The results showed that sildenafil citrate attenuated SAH-induced cerebral vasospasm in the treatment groups in terms of the diameter of the basilar artery and lipid peroxidation in the two treatment groups, but there was no difference in terms of the level of apoptosis. CONCLUSION This study indicates that further research on the therapeutic effect of sildenafil citrate can be combined with the use of any apoptosis-blocking agent for the treatment of cerebral vasospasm following experimental subarachnoid hemorrhage.

Abstract
We aimed to evaluate the relationship between 174 promoter region of the interleukin-6 (IL-6) C/G gene polymorphism and high sensitive C-reactive protein (hs-CRP), fibrinogen and carotis intima-media thickness (CIMT), body mass index, homeostatic model assessment (HOMA) insulin resistance index, serum lipid parameters, in polycystic ovary syndrome (PCOS) patients carrying a potential risk for developing cardiovascular disease (CVD). We studied 88 PCOS patients and 119 healthy controls. PCOS was defined by the Rotterdam PCOS consensus criteria. The genotype IL-6 distribution did differ between the control group (CC 10.1%, GC 63.0%, GG 29.6%) and the PCOS patients (CC 5.7%, GC 29.5%, GG 64.8%) (P < 0.001). The frequency of the polymorphic G allele was also no similar for the group with PCOS as for the control group with 79.5% and 58.4% respectively (P < 0.001). Both in PCOS patients and in control group, no statistically significant difference was determined between C/C, G/C and G/G, and blood cholesterol levels, triglyceride levels, high-density lipoprotein levels, low density lipoprotein levels, fasting blood sugar levels, insulin levels, HOMA values, CIMT measurements either on the right or left side, hs-CRP, f-testosterone, fibrinogen and 17 alpha-hydroxy-progesterone levels (P > 0.05). Gene polymorphism of IL-6 -174 G>C is a risk factor for PCOS in Turkish patients, but we found no relationship between the cardiovascular risk factors and IL-6 -174 G>C gene polymorphism in women with PCOS and healthy subjects. Our negative results in risk factors of CVD can probably be explained by the fact that metabolic parameters and endothelial systems of patients may not yet be affected in this short time of period.

Abstract
For autologous chondrocyte implantation, the chondral tissue obtained is transferred from the operating room to the laboratory using specialized carrier systems within 24 hours. Similar expenses are used for the transport of cultured chondrocytes. The purpose of this study was to find the optimal temperature, size of tissue, and time that the chondrocytes can stand without losing viability and proliferative capacity. Fresh calf cartilage was harvested and divided into 24 groups. Half of the samples were diced into 1- to 2-mm(3) pieces. All 12 groups were kept at either 4 degrees C, 25 degrees C, or 37 degrees C for 1, 3, 5, or 7 days and were seeded for cell culture. Times to reach confluence values were compared. Produced cell suspensions were grouped similarly and tested similarly. Neither the temperature nor the waiting days caused any difference in the proliferative capacity of the cells. Diced tissues yielded a shorter time to reach confluence values. Chondral tissue obtained from the patient can be transferred to the laboratory at temperatures ranging from 4 degrees C to 37 degrees C in up to 7 days. These conditions did not affect the proliferative capacity or the viability of the chondrocytes. Dicing the tissue prior to transport will shorten total culturing time. The expanded cell suspensions should be transferred at temperatures from 4 degrees C to 25 degrees C within 3 days. Specialized carrier systems to get the chondral tissue from the operating room to the laboratory and to take the expanded chondrocytes back to the operating room within hours may not be necessary.

Abstract
OBJECTIVE The aim of our study was to demonstrate demographic characteristics, presence of inflammatory markers, distribution of angiotensin-converting enzyme (ACE), tumor necrosis factor (TNF), endothelial nitric oxide synthase (eNOS) genotypes and relations among these parameters in these patients and control subjects. RESEARCH DESIGN AND METHODS Study samples were collected from 50 patients with adrenal mass and 30 control groups. The eNOS, ACE, TNF-alpha, transforming growth factor (TGF)-beta genes polymorphisms, TNF-alpha, adiponectin levels were analysed in 50 unrelated Turkish patients with a diagnosis of adrenal incidentaloma (AI). RESULTS There was statistically significant difference between TNF-alpha levels of patient and controls (p=0.048). We have not detected the connection between TGF-beta, TNF-alpha, ACE, eNOS gene polymorphism with serum TNF-alpha and adiponectin levels. In this study, we demonstrated that there were significant differences for ACE genotypes in the patients when compared to the controls (p<0.05). The percentages of the ID, DD, II genotypes for ACE gene polymorphism in the patients group were 30.0, 13.0, 7.0%, respectively. CONCLUSIONS According to different cases of eNOS, TGF-beta, ACE, and TNF-alpha gene genotypes; no statistical significant difference was found between basal cortisol, ACTH, DHEAS, metanephrine, renin, aldosterone, normetanephrine, 17-hydroxyprogesterone, 1 mg low-dose dexamethasone suppression test-cortisol response and AI size. In this study, I/D genotype was determined to be statistically higher in ACE gene in patients with AI (p=0.014).
