Effect of Electromagnetic Wave on Bone Healing in Fixed and Unfixed Conditions.

Mobile phones have come into daily life and are now one of the most frequently used devices for communication. The aim of this study was to evaluate possible effect of electromagnetic wave (EMW) with and without fixation material on bone healing.Forty male rats were exposed to fracture on tibia bone and were randomly divided into 4 groups as E(+)K(+), E(+)K(-), E(-)K(+), and E(-)K(-) where E(+) means EMW exposure and K(+) means Kirschner wire fixation. At the end of study tibia samples were taken from all the groups for the quantitative evaluation of regeneration.Significant difference was found between Group E(+)K(+) and E(-)K(+) in terms of both new bone and capillary volume.Electromagnetic wave may be harmful for bone healing with fixation whereas it has no same effect on bone regeneration without fixation.

The effect of inferomedial screw on postoperative shoulder function and mechanical alignment in proximal humerus fractures.

AIM: The aim of the study was to evaluate the clinical and radiologic results of locking plate fixation with or without inferomedial screw (IMS) in surgically treated proximal humerus fractures. PATIENTS AND METHODS: Thirty-six patients with displaced proximal humerus fractures from two centers were operated using locking plate. All of the fractures were classified according to the Neer classification. In 18 of the cases, an additional IMS running through the medial curvature of the surgical neck was used. There was no significant difference among both groups in terms of height, gender, weight, and mechanism of injury. The fractures were evaluated according to the radiographic and functional findings during follow-up period of 14 months in average (range 8-32 months). At the end of first year, shoulder radiographs were received and shoulder examinations were performed using ASES scores. Humeral head-shaft angles were measured by true AP projections. Head-shaft angle measurements were categorized as varus if <125, normal if between 125 and 145, and valgus if >145. RESULTS: Mean time for fracture healing was 18 weeks. Complete union was achieved in 35 patients by the end of 6 months. In one of the 18 displaced proximal humerus fractures of IMS (+) group, the head-shaft angle was measured to be <125, whereas six patients had varus deviation in IMS (-) group at follow-up (p < 0.05). Mean ASES scores of IMS (+) group and IMS (-) group were 58.21 ± 5.82 and 38.61 ± 3.44, respectively (p < 0.001). CONCLUSION: Use of inferomedial screw running through the medial curvature of surgical neck prevents varus deformity and improves functional outcome after surgical treatment for proximal humerus fractures.

Similarities and Differences Between Gerontal and Young Patients with Acute Pancreatitis: Evaluation of Clinical Characteristics and Outcomes.

BACKGROUND: Acute pancreatitis is an abrupt inflammatory disease of the exocrine pancreas and it can occur in different severities. It is becoming more common and more mortal in the gerontal population. The aim of our study was to explore the similarities and differences between young and gerontal patients with acute pancreatitis, with a special emphasis on patients over 80 years of age. METHODS: Medical records of patients (n = 1150) with acute pancreatitis were analyzed retrospectively. Several scoring systems including Bedside index for severity in acute pancreatitis, Ranson's score, Harmless acute pancreatitis score, Acute Physiology and Chronic Health Evaluation, Balthazar Grade, Glasgow score, and Japanese severity score were applied at admission. Patients were divided into 3 groups; group I, young group (n = 706), if they were aged <65 years; group II, older group (n = 338), if they were aged ≥65 years to <80 years; group III, octogenarian group (n = 106), if they were aged ≥ 0 years. RESULTS: In total, 1150 patients with acute pancreatitis were analyzed. Octogenarian group (n = 42, 39.6%) showed a more severe acute pancreatitis compared to patients in group I (n = 15, 2.1%) and II (n = 50, 14.8%, P < .001). Complications were more common in patients in group III (P < .001). Mortality rate was higher in patients in group III (n = 53, 50%) compared to group I (n = 8, 1.1%) and group II (n = 53, 15.7%) (P < .001). CONCLUSION: Gerontal patients with acute pancreatitis tend to have more severe disease and systemic and local complications. Mortality rates were higher in older patients compared to younger patients.

Investigation of double-carbapenem efficiency in experimental sepsis of colistin-resistant Klebsiella pneumoniae.

OBJECTIVE: Klebsiella pneumoniae, a Gram-negative pathogen, especially which produces carbapenemase, is seen as a major threat to public health due to rapid plasmid-mediated spread of resistance and limited therapeutic options available for treatment. Although colistin has been recognized as a "last resort" antimicrobial for multidrug-resistant K. pneumoniae infections, these isolates have developed resistance to colistin as a result of its intensive use. The aim of this study was to evaluate the efficacy of double-carbapenem treatment of colistin-resistant K. pneumoniae experimental sepsis in mice. METHODS: In the study, 8-10-week-old Balb-c mice were divided as control groups (positive and negative) and treatment groups (colistin, ertapenem+meropenem, and ertapenem+meropenem+colistin). Sepsis was developed in mice by an intraperitoneal injection of colistin resistant K. pneumoniae. Antibiotics were given intraperitoneally 3 h after bacterial inoculation. Mice in each subgroup were sacrificed with overdose anesthetic at the end of 24-48 h and cultures were made from the heart, lung, liver, and spleen. Furthermore, homogenates of lung and liver were used to detect the number of colony-forming units per gram. Bacterial clearance was evaluated in lung and liver at different time points. RESULTS: When the quantitative bacterial loads in the lung and liver tissues are evaluated, no statistically significant difference was observed between different antibiotic treatments (p>0.05). All three treatment options were not effective, especially in 24 h. Only the decrease in bacterial load at the 48th h of the group treated with ertapenem + meropenem + colistin was found significant (p<0.05) compared to the 24 h. CONCLUSION: In the light of these data, it was understood that double-carbapenem application was not sufficient in the treatment of experimental sepsis in mice with colistin-resistant K. pneumoniae. Furthermore, ertapenem + meropenem + colistin combined therapy was not found to be superior to colistin monotherapy or double-carbapenem therapy.

Endoscopic retrograde cholangiography by double balloon enteroscopy in patients with Roux-en-Y hepaticojejunostomy.

BACKGROUND: In patients with Roux-en-Y hepaticojejunostomy (HJ), endoscopic retrograde cholangiography (ERC) cannot usually be achieved since the anastomosis is not reachable via standard duodenoscope. In this study, we report our experience with ERC using double balloon enteroscope (DBE) (DBE-ERC) in patients with HJ. METHODS: The DBE-ERC procedures performed since the index case done dated May 3, 2006 have been overviewed. RESULTS: Fourteen patients underwent the procedure. DBE-ERC was successful in all but one patient, for whom the anastomosis could not be reached (success rate to reach anastomosis: 92.9%). The remaining 13 patients (7 female, 6 male; age 28-61 years, mean 45.3 years) had 20 sessions of DBE-ERC. The cannulation of the bile duct was achieved in all patients. The procedures, such as sphincteroplasty, dilatation, stone extraction and stent placement, were performed. Therapeutic procedures were all successful, except for in a single patient, who had the common bile duct filled with multiple stones and was referred for surgery. Three patients who had anastomotic stenosis treated by stenting are symptom free on follow-up at 3, 9 and 12 months, respectively, after stent removal. Retroperitoneal air was detected in a patient following stricturoplasty, but recovery was attained with medical treatment alone. Mean duration of the procedures was 75 +/- 62 min. CONCLUSION: DBE-ERCP enables us to perform ERC in a group of patients for whom it was impossible previously. Further experience is needed to evaluate its therapeutic efficacy compared with alternative methods.

Fear of hypoglycemia in adults with diabetes mellitus switching to treatment with IDegAsp co-formulation to examine real-world setting: an observational study (The HATICE study).

OBJECTIVES: To evaluate the clinical results of insulin degludec/aspart (IDEgAsp) therapy and its effect on the fear of hypoglycemia. METHODS: A prospective observational study has been conducted through surveys of 36 patients using insulin because of type 2 diabetes mellitus who initiated treatment with IDegAsp switching from other insulins. Patients, 18-75 years old, were recruited to the study, consecutively. Participants' age, gender, height, weight, body mass index (BMI), daily insulin dose, glycated hemoglobin (HbA1c), hypoglycemia rate, hypoglycemia fear survey (HFS) were recorded at the beginning of the study. By the end of 12th month, data was re-measured and compared with each other. RESULTS: HbA1c was declined by mean of -1.59% (95% CI -1.06 to -2.12, p<0.001). There was also a significant decrease in mean, daily insulin dose, weight and BMI values of patients via IDegAsp. While there was an increase in the amount of dipeptidyl peptidase 4-inhibitors (DPP4-i) and sodium-glucose co-transporter 2-inhibitors (SGLT2-i), there was a decrease in daily injection frequency. There was also a significant decrease in the median values of monthly hypoglycemia rate (from 2.0 to 1.0, p<0.001) and the entire HFS scores (HFS-T: from 1.09 to 0.73, p<0.001; HFS-B: from 0.83 to 0.60, p<0.001; HFS-W: from 1.33 to 0.88, p<0.001). There was a strong positive correlation between ΔHFS-B and daily injection frequency (Rho: 0.398; P: 0.016). CONCLUSIONS: IDegAsp co-formulation, combined with DPP4-i and/or SGLT2-i, can provide usefulness in terms of rates of hypoglycemia, reduced HbA1c, less injection administration, and decreased the fear of hypoglycemia in diabetics.

[Neuraxial anesthesia after local anesthesia for management of percutaneous vertebroplasty complication during vertebroplasty]. / Bloqueio neuroaxial após anestesia local para manejo de complicação de vertebroplastia percutânea durante vertebroplastia.

Percutaneous vertebroplasty is a relatively safe, simple and commonly performed interventional procedure for the management of vertebral compression fractures. However, serious complications are rarely reported in the procedure. Those are pulmonary embolism, severe infection, paraplegia and an occurrence of a new fracture in an adjacent vertebra after vertebroplasty. Acute complications are generally associated with the procedure. We present the case of neuraxial anesthesia, developed after local anesthesia with 8mL of 2% prilocaine, in a 68-year-old woman who underwent percutaneous vertebroplasty after an osteoporotic collapsed fracture in the L1 vertebra due to trauma. To our knowledge, this is the first case in the literature.

NOD2/CARD15, NOD1/CARD4, and ICAM-1 gene polymorphisms in Turkish patients with inflammatory bowel disease.

PURPOSE: The genetic susceptibility of people with certain NOD2/CARD15, NOD1/CARD4, and ICAM-1 gene variants to inflammatory bowel disease is still under investigation. The aim of this study was to investigate polymorphisms in the NOD2/CARD15 (R702W, G908R, and 3020insC), NOD1/CARD4 (E266K, D372N), and ICAM-1 (G241R, K469E) genes, which are known to be associated with inflammation, in Turkish patients with inflammatory bowel disease and healthy control groups. METHODS: The genotypes of 70 patients with endoscopically and histopathologically diagnosed Crohn's disease (38 men, 32 women; mean age, 38.8 +/- 1.3), 120 patients with ulcerative colitis (67 men, 53 women; mean age, 41.7 +/- 1.3) and 106 healthy control subjects (37 men, 69 women; mean age, 35.7 +/- 1.4), who stated that they had never had any prior bowel disease history, were compared. A polymerase chain reaction-restriction fragment length polymorphism analysis was performed for two variants of the ICAM-1 gene, the three main variants of the NOD2/CARD15 gene, and the E266K variant of the NOD1/CARD4 gene, and DNA sequencing was used for the D372N polymorphism of the NOD1/CARD4 gene. RESULTS: In this study, the three previously described Crohn's disease-predisposing variants of the NOD2/CARD15 gene and the polymorphisms examined in the NOD1/CARD4 and ICAM-1 genes were not found to be associated with ulcerative colitis or Crohn's disease. CONCLUSIONS: These findings suggest that the polymorphisms observed in the NOD2/CARD15, NOD1/CARD4, and ICAM-1 genes are not genetic susceptibility factors for Crohn's disease or ulcerative colitis in Turkey.

An evaluation of the functional and radiological results of percutaneous vertebroplasty versus conservative treatment for acute symptomatic osteoporotic spinal fractures.

PURPOSE: This study aimed to compare the results of the two different treatment regimens (percutaneous vertebroplasty (PV) and conservative treatment (CT)) regarding to efficacy, quality of life, functional and radiological results in patients with acute osteoporotic vertebral compression fractures (OVF). METHODS: The study comprised 83 patients who presented with complaints of OVF associated with osteoporosis and were treated with CT (37) or PV (46). All patients were evaluated according to preoperative and postoperative visual analogue scale (VAS), Oswestry disability index (ODI) and plain radiographs. RESULTS: All patients in VP group reported a significant decrease in pain at 1st day postoperative. While Pain relief and functional outcomes were significantly better in PV group than CT at 1st and 3rd months according to VAS and ODI scores, there were no statistically significant differences between the groups at 6th months follow-up. The mean preoperative local sagittal Cobb angle (LSCA) and the mean vertebra corpus mid-level height (MVCH) were 42.3° and 14.6 mm in the PV group, while they were measured as 39.8° and 15.7 mm in CT group, respectively. 15.6° decreasing the LSCA and 10.2 mm increasing MVCH were noted in the PV group at the 6th month follow-up. While LSCA increased 19.1° and MVCH decreased 7.6mm in CT group at same time period (p<0.001). CONCLUSIONS: Compared to the CT group, PV provides a rapid decrease of pain and an early return to daily life activities. Although improvement was observed on the radiological findings following treatment in the PV group, PV may not enhance the quality of life in patients with acute OVF at 6th months follow up.

Effect of interferon and ribavirin combined with amantadine in interferon and ribavirin non-responder patients with chronic hepatitis C (genotype 1).

AIM: To evaluate the efficacy of amantadine plus interferon-alpha and ribavirin in non-responder patients with chronic hepatitis C. METHODS: Twenty-six non-responder patients received the regimen of IFN-alpha-2a at a dose of 6 million units three times a week, 1 000-1 200 mg of ribavirin daily, and 200 mg of amantadine daily in divided doses over 48 wk. After the end of treatment, at the 72nd wk, a sustained viral response rate was determined. RESULTS: An early (after 12 wk of therapy) response was seen in 34.6% (9/26) of patients. Response rate at the 24th wk was 42.3% (11/26). End of treatment response (ETR) was 53.8% (14/26). Sustained viral response (SVR) was 42.3% (11/26). There was a statistically significant difference between 0 and 12 wk (P = 0.04), 0 and 24 wk (P = 0.01), 0 and 48 wk (P = 0.00), and 0 and 72 wk (P = 0.001). No patient had severe adverse effects during the treatment. CONCLUSION: Combination regimen of interferon-alpha, ribavirin and amantadine can enhance sustained viral response on IFN-alpha and ribavirin non-responder patients with HCV. Triple therapy with amantadine should be evaluated in further studies.

Treatment of osteoporotic vertebral compression fractures with percutaneous vertebroplasty under local anesthesia: clinical and radiological results.

BACKGROUND: Vertebroplasty (VP) is a commonly used method for the treatment of osteoporotic vertebral fractures (OVF). The aim of this study is to analyze retrospectively the efficacy of PV in symptomatic osteoprotic spine fractures. METHODS: Patients with symptomatic osteoporotic spine fractures were included in our study. Visual analog scale and demographic characteristics were used for clinical examination, local wedge angle and the central height of the vertebral body were measured preoperatively and postoperatively. RESULTS: 95 patients (72 female, 23 male) were included and 118 level vertebroplasty were performed. There was statistical significance in the differences of preoperative VAS scores compared to postoperative first day, first month and sixth month. The radiologic assessment of the mean local wedge angle correction at the postoperative sixth month, was 13.9 and mean increase of mid height of vertebral body was 7.9 mm, but it was not statistically significant. CONCLUSION: VP is at an important point as a minimally invasive method, that provides rapid pain relief in symptomatic osteoporotic vertebral fractures and that prevents the patient being bed-dependent. It is a reliable surgical method, being an alternative to open surgery with minimal complications in patients with comorbidities, which can be arapidley applied and decreases the potential spinal deformity after the fracture and prevents the progression of deformity.

Panton-Valentine leukocidin positive Staphylococcus aureus infection in childhood: a case report.

Staphylococcus aureus is a common cause of musculoskeletal infections. Panton-Valentine leukocidin (PVL) is an exotoxin produced by S. aureus and is an important virulence factor. PVL-positive S. aureus infections have been associated with soft tissue infections and necrotizing pneumonia. In this case report, the clinical course of a 13-year-old boy who was admitted with right hip pain and fever, diagnosed with a gluteal abscess and incidentally discovered multiple cavitary pulmonary lesions, and had a methicillin susceptible and PVL-producing S. aureus (MSSA) extracted from the abscess culture is presented. The related literature is also reviewed.

Can Serum ST2 Levels Be Used as a Marker of Fibrosis in Chronic Hepatitis B Infection?

Interleukin 33 (IL-33) is a cytokine belonging to the IL-1 superfamily. Soluble ST2 (sST2) binds to IL-33 and by functioning as trap receptor inhibits signal sending to Th2 via transmembrane ST2. Because Th2-type cytokines play an important role in fibrosis, the aim of this study is to determine whether sST2 can be used as a marker of fibrosis in chronic hepatitis B (CHB) patients or not.The study included 19 healthy controls, 54 patients with CHB, and 14 patients with cirrhosis because of CHB. The aspartate aminotransferase-to-platelet ratio index (APRI) and fibrosis index based on the 4 factors (FIB-4) scores also calculated, and correlations between liver biopsies, sST2 levels, and these scores were analyzed in CHB and cirrhosis patients.The sST2 levels in patients with CHB were significantly higher than those in the control group subjects (median: 1133 pg/mL vs 762.5 pg/mL, respectively [P = 0.035]). In CHB patients, the METAVIR fibrosis score (stages from 0 to 4) showed a moderate correlation with serum sST2 level (r = 0.396, P = 0.004) and a weak correlation with FIB-4 score (r = 0.359, P = 0.008), but no correlation with APRI score (r = 0.253, P = 0.06). The under the curve value of serum sST2 was 0.68, and its prediction of significant fibrosis (METAVIR score ≥2) in values >674 pg/mL had a sensitivity of 91.7% and specificity of 40% (P = 0.009). According to multiple logistic regression analysis, only METAVIR fibrosis stage was found to be an independent predictor of serum sST2 elevation in CHB patients (P = 0.04).The sST2 level can be used for differentiating significant fibrosis from mild fibrosis in CHB patients. However, the efficacy of this marker should be verified by larger studies in the future.

Bilateral congenital absence of the abductor pollicis brevis muscle: a case report.

Congenital absence of the abductor pollicis brevis is a very rare condition and is usually associated with other congenital anomalies. Here we report a case of bilateral congenital absence of the abductor pollicis brevis without any other abnormalities, which has not been previously reported. A 24-year-old Caucasian male patient presented to our clinic with flattening in the palmar region, pain and discomfort in writing, and weakness in both hands. USG and MRI revealed bilateral absence of the abductor pollicis brevis muscle. Bilateral congenital absence of the abductor pollicis brevis muscle requires no treatment due to satisfactory hand function, and results in cosmetic problems. Congenital absence of the abductor pollicis brevis muscle should be kept in mind in patients with flattening of the thenar eminences.

Isolated carpal scaphoid dislocation.

Isolated scaphoid dislocations are very rare. Options for the treatment of dislocation of the scaphoid include closed reduction and casting, closed reduction and percutaneous pinning, and open reduction and ligament repair. We report a case of this rare injury which was treated with open reduction, pinning and ligament repair.

Supercharged dorsoulnar island flap: a case report and review of the literature.

Complicated hand and wrist defects require durable and pliable tissues which are offered by flaps, instead of skin grafts. Various dorsoulnar flap options have been used in the regional flap armamentarium of the upper limb. Poor venous drainage may be a considerable handicap when moderate to large skin paddle dorsoulnar flaps are used. In the present case, we aimed to reduce the risk of necrosis by supercharging the dorsoulnar island flap. The current literature regarding dorsoulnar island flap has also been reviewed with focus on this flap. This technique has successfully been used for a complex wrist defect in a 48-year-old man. Postoperative follow up was one year. The flap survived completely with perfect hand function. We think this modification can prevent possible venous stress in the pedicled and free dorsoulnar flaps by obtaining extraveneous drainage. The method is simple, does not need sophisticated microsurgical procedure and longer operative time.

Presence and diagnosis of amebic infestation in Turkish patients with active ulcerative colitis.

BACKGROUND: It is difficult to definitively diagnose acute amebiasis, particularly when this condition is superimposed on inflammatory bowel disease. Our goals in this study were to determine the prevalence of amebiasis in individuals with active ulcerative colitis, and to identify clinical and laboratory parameters that are of value for diagnosing amebiasis in this patient group. METHODS: The subjects were 111 patients (76 women, 35 men) with confirmed active ulcerative colitis who attended our hospital's Inflammatory Bowel Disease Outpatient Clinic between May 2002 and March 2006. In each case, a detailed medical history was collected, blood samples were tested for inflammatory markers, and stool samples were evaluated for presence of amebae using an Enzyme-Linked Immunosorbent Assay (ELISA) for detection of Entamoeba histolytica antigen. The clinical and laboratory variables for the ELISA-positive and ELISA-negative groups were compared. RESULTS: Amebiasis was detected in 35 (31.5%) of the subjects. Patient age, disease duration, endoscopic activity index, serum C-reactive protein level, and white blood cell count were not useful for diagnosing amebiasis in this patient group. CONCLUSIONS: Given the high rate of amebiasis observed in our patients with active ulcerative colitis, we recommend that, in Turkey any individual with ulcerative colitis who presents with symptoms of disease activation should be tested for ameba using antigen detection kits. A high index of suspicion is especially important in any region where E. histolytica is endemic.
