Predicting difficult airway in morbidly obese patients using ultrasound.

Background/aim: Difficult mask ventilation and difficult intubation are more common in obese patients. Ultrasound is a reliable and noninvasive method for evaluating the airway. The aim of this study was to investigate the contribution and availability of anterior neck soft tissue (ANS) thickness at different levels, tongue volume (TV), hyomental distance (HMD), the ratio of preepiglottic distance to distance between the epiglottis and the midpoint of vocal cords (PE/E-VC) measured by ultrasonography in predicting difficult airway in morbidly obese patients. Materials and methods: Between March 2020 and November 2020, patients aged ≥18 years with a body mass index (BMI) of ≥40 kg/m2 who underwent elective surgery under general anesthesia were included in this prospective study at Firat University Hospital. During the preoperative evaluation of patients, ultrasound was used to measure and record TV, ANS thickness at different levels, HMD, and ratio of PE/E-VC. Patients with difficult intubation were identified using the Cormack-Lehane classification system. Patients whohad difficulties with balloon mask ventilation were recorded. Subsequently, the parameters of patients with easy and difficult intubation were compared. In addition, the parameters of patients with easy and difficult mask ventilation were also compared. Results: The preepiglottic ANS thickness at the level of the thyrohyoid membrane and the PE/E-VC value in obese patients with difficult intubation were significantly greater than in obese patients with easy intubation (p < 0.001). In addition, TV (p < 0.001), preepiglottic ANS thickness at the thyrohyoid membrane level (p < 0.001), ANS thickness at the thyroid isthmus level (p = 0.002), ANS-suprasternal notch thickness (p = 0.004), and PE/E-VC (p = 0.005) values were significantly greater in obese patients with difficult mask ventilation. Conclusion: Ultrasound may be a useful tool for predicting difficult airway and difficult mask ventilation. For this purpose, ANS thickness at different levels, PE/E-VC, and TV values measured by ultrasound can be used.

The investigation of incidence and multidetector computed tomography findings of median arcuate ligament syndrome

Background/aim: This study aims to evaluate the incidence and multidetector computed tomography (MDCT) findings of median arcuate ligament syndrome (MALS). Materials and methods: Between January 2010 and September 2016 a total of 4028 patients who underwent angiography for MDCT based on the clinical indications for abdominal pain were retrospectively analyzed. Results: The typical signs of MALS were identified in a total of 141 (3.5%) patients. Among all patients, 84 (59%) were male and 57 (41%) were female. The mean age was 42 years (range: 24 to 71 years). The incidence of celiac artery stenosis was 30% to 50% in 45 patients (32%) and 51% to 90% in 96 patients (68%). Poststenotic dilatation was reported in 74 patients (52%). Collateral vascular structures from the superior mesenteric artery were observed in 5 patients (3.5%). Twenty-one patients (14.9%) underwent laparoscopic surgery with significant stenosis. Conclusion: MALS is a rare vascular pathology. It is especially important to recognize the presence of MALS with an epigastric pain that increases with expiration in adults and also its etiology before interventional procedures. MDCT visualization made the diagnosis of MALS easy.

An Overlooked Potentially Treatable Disorder: Idiopathic Mesenteric Panniculitis.

OBJECTIVE: The aim of this study was to determine the prevalence of mesenteric panniculitis (MP) and to describe its clinical characteristics, therapy, and outcome. SUBJECTS AND METHODS: This retrospective study was carried out among patients with MP based on computed tomography (CT) scans from January 2012 to December 2015. The CT images were reanalyzed by study radiologists to confirm the previous MP diagnosis. Patients were divided into 2 groups, i.e., idiopathic and secondary, based on the presence or absence of associated predisposing factors such as trauma, malignancy, autoimmune disorders, ischemia, or previous abdominal surgery. The clinical characteristics of the 2 groups, as well as treatments, were assessed. RESULTS: Among the 19,869 CT scans, 36 patients (0.18%) with MP were identified (i.e., 19 [53%] females and 17 [47%] males). The median age was 54 years (range 26 - 76). Twenty-four patients (67%) were categorized into the idiopathic group. Malignancy was the predisposing factor in 8 (22%) of those patients. Furthermore, abdominal pain was the cardinal symptom observed in 22 patients (92%) in the idiopathic group. In the idiopathic group, 15 patients (63%) were treated with antibiotics and 16 (67%) were treated with nonsteroidal anti-inflammatory drugs (NSAID). One unresponsive patient was treated with colchicine. Symptomatic relief was achieved in all of the treated patients. CONCLUSION: In this study, a symptomatic idiopathic subgroup of patients with MP did not have any associated disorder. The response to treatment with antibiotics and NSAID was effective in most of the patients. Based on these findings, anti-inflammatory treatments beyond NSAID and surgery should be reserved for patients who are unresponsive to antibiotics and NSAID.

Unusual presentation; seeding of tumor after biopsy for hepatocellular carcinoma.

Hepatocellular cancer is one of the most common and fatal cancer tumor worldwide. However, the obtained results are questionable in terms of medical treatment of hepatocellular cancer. The muscle, soft tissue and cutaneous metastases of hepatocellular cancer, for instance, are rare and may result from interventional procedures. Seeding of tumor along the biopsy needle upon percutaneous biopsy is a very rare phenomenon. We report a very rare case of a 79 -year- old man, known to be hepatitis C virus carrier with a metastatic tumor in abdominal wall caused by seeding of tumor after three years following a percutaneous biopsy procedure. Even years later, after a biopsy procedure for diagnostic purposes and may be soft tissue metastases. This complication is a very rare condition that should not be ignored but can be observed. The biopsy requirement should be questioned closely and avoided unnecessary biopsy procedures.

The gut-pancreas axis: investigating the relationship between microbiota metabolites and pancreatic steatosis.

The prevalence of pancreatic steatosis has increased and it has been linked to the rising prevalence of metabolic syndrome. Metabolic syndrome is known to have a strong connection with changes in intestinal microbiota. The aim of this study was to explore the relationship between pancreatic steatosis and the levels of trimethylamine N-oxide (TMAO) and butyrate. In this study, 136 individuals were randomly selected from outpatient clinics at Firat University Hospital. The study evaluated their demographic characteristics, anthropometric measurements, and biochemical parameters. The presence of pancreatic steatosis was assessed using abdominal ultrasonography. Additionally, the levels of TMAO and butyrate were measured. The mean age of individuals in the study was 44.5 ± 14.6. 84 of the subjects were females. Using the waist circumference, 61 were considered obese and 34 overweight. The detection rate of pancreatic steatosis was found to be 70.6%. The study found that individuals with steatosis had higher average age, presence of hepatic steatosis, BMI, waist circumference measurements, and presence of metabolic syndrome than those without steatosis. A significantly higher butyrate level was detected in those without steatosis (p = 0.001). TMAO levels were slightly higher in patients without steatosis than in those with steatosis; however, this was insignificant. Pancreatic steatosis is highly associated with alterations in levels of microbiota metabolites, indicating a potential role of these metabolites in the pathogenesis of the disease and subsequent therapeutic targets. Several other factors, such as age, hepatic steatosis, diabetes, and waist circumference, have also been identified as potential predictors of pancreatic steatosis.

Characteristics of Hepatobiliary Fascioliasis and the Role of Endoscopic Retrograde Cholangiopancreatography in Management: A Single Center Experience.

Background: Hepatobiliary fascioliasis has two phases, each requiring specific management approaches. Triclabendazole has been widely effective in treating the two phases of clinical fascioliasis and endoscopic retrograde cholangiopancreatography (ERCP) in the biliary phase. We aimed to characterize presentations of hepatobiliary fascioliasis and highlight the role of ERCP in management. Subjects and methods: This retrospective cohort includes patients diagnosed with clinical hepatobiliary fascioliasis between January 2013 and December 2022. Demographic data, clinical presentation, laboratory and radiological investigations, treatment, and endoscopy reports were collected from the records of 62 participants. Patients were divided into two groups: acute hepatic and chronic biliary phases. Results: Thirty-six patients were in the biliary phase, and 26 were in the hepatic phase. All patients were from rural areas, and females were predominant (76%). Hypereosinophilia was detected in 92% of acute cases and 58% of chronic biliary cases. In chronic biliary cases, the levels of liver biochemicals, including alanine transaminase (ALT), aspartate aminotransferase (AST), gamma-glutamyltransferase (GGT), and bilirubin, were higher at levels of 189 ± 76, 127 ± 47, 268 ± 77, and 2.4 ± 0.7 respectively, compared to acute hepatic cases, 35.6 ± 8.2, 32.7 ± 4.3, 69.2 ± 45.45, and 0.58 ± 0.01. The corresponding P-values were 0.003, 0.001, <0.001, and <0.001, respectively. Triclabendazole effectively cured 93.5% of patients and was used in combination with ERCP in biliary-phase cases where the fluke was extracted from the biliary system in 34 patients (94.4%). Three patients (8.8%) were diagnosed with post-ERCP pancreatitis. None of the patients experienced bleeding, perforation, or required biliary stenting. Conclusion: Clinical fascioliasis could manifest in acute hepatic or chronic biliary phases. Hypereosinophilia was more evident in the hepatic phases, while ALT, AST, GGT, and bilirubin were higher in the biliary phase. Triclabendazole is effective in the hepatic phase and when combined with ERCP in the biliary phase. ERCP is highly effective for relieving obstruction and treating biliary fascioliasis.

Initial experience of 3 tesla apparent diffusion coefficient values in differentiating benign and malignant thyroid nodules.

PURPOSE: To evaluate the role of diffusion-weighted magnetic resonance imaging (DWMRI) in differentiating benign and malignant thyroid nodules using a 3 Tesla (T) MRI scanner. MATERIALS AND METHODS: Twenty-eight nodules in 25 patients and 14 healthy control cases were included in the study. DWMRI was acquired with 6 b values with a 3T MRI scanner. The apparent diffusion coefficient (ADC) values of the nodules were calculated from reconstructed ADC map images and were compared with the final histopathological diagnoses. RESULTS: The mean ADC value of the benign nodules was 1548 ± 353.4 (×10(-6) mm(2) /s), and the mean ADC of the malignant nodules was 814 ± 177.12 (×10(-6) mm(2) /s). The normal thyroid tissue had a mean ADC value of 1323.43 ± 210.35 × 10(-6) mm(2) /s (958-1689 × 10(-6) mm(2) /s) in the healthy control group. The ADC values were significantly different among the three groups (P = 0.001). An ADC value of 905 × 10(-6) mm(2) /s was determined to be the cutoff value for differentiating benign and malignant nodules, with 90% (55.5-98.3) sensitivity and 100% (81.3-100.0) specificity. CONCLUSION: This study suggests that the ADC values of nodules measured with a 3T MRI scanner could help in differentiating benign thyroid nodules from malignant nodules.

Evaluation of abdominal computed tomography findings in patients with COVID-19: a multicenter study

PURPOSE: To evaluate the frequency of abdominal computed tomography (CT) findings in patients with coronavirus disease-2019 (COVID-19) and interrogate the relationship between abdominal CT findings and patient demographic features, clinical findings, and laboratory test results as well as the CT atherosclerosis score in the abdominal aorta. METHODS: This study was designed as a multicenter retrospective study. The abdominal CT findings of 1.181 patients with positive abdominal symptoms from 26 tertiary medical centers with a positive polymerase chain-reaction test for severe acute respiratory syndrome coronavirus 2 were reviewed. The frequency of ischemic and non-ischemic CT findings as well as the association between CT findings, clinical features, and abdominal aortic calcific atherosclerosis score (AA-CAS) were recorded. RESULTS: Ischemic and non-ischemic abdominal CT findings were detected in 240 (20.3%) and 328 (27.7%) patients, respectively. In 147 patients (12.4%), intra-abdominal malignancy was present. The most frequent ischemic abdominal CT findings were bowel wall thickening (n = 120; 10.2%) and perivascular infiltration (n = 40; 3.4%). As for non-ischemic findings, colitis (n = 91; 7.7%) and small bowel inflammation (n = 73; 6.2%) constituted the most frequent disease processes. The duration of hospital stay was found to be higher in patients with abdominal CT findings than in patients without any positive findings (13.8 ± 13 vs. 10.4 ± 12.8 days, P < 0.001). The frequency of abdominal CT findings was significantly higher in patients who did not survive the infection than in patients who were discharged after recovery (41.7% vs. 27.4%, P < 0.001). Increased AA-CAS was found to be associated with a higher risk of ischemic conditions in abdominal CT examinations. CONCLUSION: Abdominal symptoms in patients with COVID-19 are usually associated with positive CT findings. The presence of ischemic findings on CT correlates with poor COVID-19 outcomes. A high AA-CAS is associated with abdominal ischemic findings in patients with COVID-19.

The effect of anisometropic amblyopia on retrobulbar blood flow parameters. Anisometropic amblyopia and retrobulbar blood flow.

To look for a correlation between or the effect of anisometropia amblyopia on retrobulbar blood flow parameters. Peak systolic velocity (PSV) and end-diastolic velocity (EDV) of the ophthalmic artery (OA), central retinal artery (CRA), and temporal posterior ciliary artery (tPCA) were measured with color Doppler imaging, and systolic/diastolic ratio, resistivity index (RI), and pulsatility index (PI) were computed in 42 patients with anisometropic amblyopia. The mean PSV of OA, CRA, and tPCA in amblyopic and fellow eyes were 62.69 ± 24.04, 62.64 ± 20.18; 9.28 ± 3.71, 10.27 ± 4.18; 10.81 ± 4.59, 11.28 ± 4.91, respectively. The mean EDV of OA, CRA, and tPCA in amblyopic and fellow eyes were 15.87 ± 11.31, 14.52 ± 6.54; 2.48 ± 1.17, 2.62 ± 2.06; 3.04 ± 2.34, 3.14 ± 2.18, respectively. The mean RI of OA, CRA, and tPCA in amblyopic and fellow eyes were 0.76 ± 0.08, 0.76 ± 0.08; 0.72 ± 0.08, 0.74 ± 0.95; 0.72 ± 0.09, 0.72 ± 0.08, respectively. The mean PI of OA, CRA, and tPCA in amblyopic and fellow eyes were 1.77 ± 0.42, 1.81 ± 0.46; 01.58 ± 0.42, 1.59 ± 0.43; 1.54 ± 0.43, 1.58 ± 0.49, respectively. There was no statistically significant difference in any of the measured parameters between the amblyopic and fellow eyes. Anisometropic amblyopia did not cause any change in retrobulbar blood flow in amblyopic eyes.

Median arcuate ligament syndrome noticed during pancreaticoduodenectomy.

Median arcuate ligament syndrome (MALS) occurs as a result of compression of the celiac artery by a fibrous band called the median ligament, which originates from the diaphragmatic crus. The prevalence of MALS has been reported as 10-24% among patients. The etiology is not clear. The components of the clinical triad are a chronic post-prandial pain, epigastric murmur and weight loss. Diagnosis is based on clinical and radiological findings. MALS has been reported in a small portion of patients undergoing pancreaticoduodenectomy. Most of the patients have been diagnosed prior to surgery.

Sonoelastrographic finding of Achilles tendon in patients with ankylosing spondylitis and acromegaly.

OBJECTIVES: Achilles tendinopathy can be noticed in both acromegaly and ankylosing spondylitis (AS). Acromegaly patients presenting with tendinopathy findings may be confused with AS findings. In this study, sonoelastrographic findings of Achilles tendon are explored in patients with AS and acromegaly. METHODS: 25 patients with AS, 30 patients with acromegaly, and 18 healthy controls were enrolled in the study. Achilles tendon was evaluated by sonoelastography in all the study participants. RESULTS: The thickness of Achilles tendon in neutral positions was higher in acromegaly patients than those in AS patients. The sonoelastography measurement of Achilles tendon was increased in acromegaly patients when compared to the control group and AS patients. CONCLUSION: The thickness of Achilles tendon can increase in patients with acromegaly and AS. However, the sonoelastographic features of Achilles tendon can be similar in patients with AS and acromegaly.

A Case of Intrapancreatic Accessory Spleen Mimicking a Pancreatic Metastasis on the 18 F-FDG PET/CT Scan: A Case with Breast Cancer.

The accessory spleen is a focus of splenic tissue which is separated from the main of the spleen. Although accessory spleens are generally recognized on computed tomography (CT), intrapancreatic accessory spleen (IPAS) may be mistaken for other pancreatic tail lesions. We report a case of IPAS mimicking a pancreatic metastasis on the 18 F-fluorodeoxyglucose positron emission tomography/computed tomography ( 18 F-FDG PET/CT). A 41-year-old with diagnosed breast cancer (invasive ductal carcinoma) woman patient underwent an 18 F-FDG PET/CT for metastasis screening and staging. 18 F-FDG PET/CT showed a focal uptake in the pancreatic tail. The patient underwent a contrast-enhanced CT and magnetic resonance imaging (MRI) for lesion characterization. The density and intensity of lesion were similar to spleen on all phases and all sequences. The lesion was evaluated as IPAS. The diagnosis was confirmed by endoscopic ultrasound (EUS) biopsy. A case of IPAS positive at 18 F-FDG PET/CT could not found in the literature. We present a case of IPAS mimicking a pancreatic metastasis positive at 18 F-FDG PET/CT.

Increased serum chemerin levels associated with carotid intima-media thickness.

BACKGROUND: Elevated levels of chemerin can predict future ischemic cerebrovascular disease. Although chemerin is thought to play a role in atherosclerotic inflammation, whether circulating chemerin levels are associated with the severity of atherosclerosis remains to be determined. OBJECTIVES: Through the use of carotid Doppler ultrasonography, our aim in this study was to investigate the relationships of serum chemerin levels with carotid intima-media thickness (CIMT) as an indicator of generalized atherosclerosis. METHODS: This study compared 40 patients with ischemic stroke and 40 healthy subjects. Measurements were made at end-diastole using color Doppler ultrasonography (CDUS) after a 5-min rest interval in a quiet and dark room. CIMT was defined as the distance between the innermost edge of the luminal echo to the innermost edge of the media/adventitia echo. CIMT was measured in the posterior wall of both common carotid arteries within 1 cm proximally to the bulbus. Three measurements were made on both sides and the average measurement was taken as the CIMT. Serum chemerin levels were determined in all patients and healthy subjects. RESULTS: Serum chemerin levels were significantly higher in the patient group than in the control group (p=0.004). Serum chemerin levels were positively correlated with CIMT (p<0.05). There was a significant difference between the groups with regard to CIMT (p<0.001). CONCLUSION: Elevated serum chemerin levels appear to be associated with CIMT, thus suggesting that a link exists between chemerin and atherosclerotic ischemic cerebrovascular disease.

Percutaneous management of complicated parapneumonic effusion and empyema after surgical tube thoracostomy failure in children: a retrospective study.

PURPOSE: We aimed to evaluate the results of percutaneous management of complicated parapneumonic effusions (PPE) and empyema after surgical tube thoracostomy failure in children. METHODS: A total of 84 children treated percutaneously after surgical tube thoracostomy failure between 2004 and 2019 were included to this retrospective study. Technical success was defined as appropriate placement of the drainage catheter. Clinical success was defined as complete resolution of infection both clinically and radiologically. Management protocol included imaging-guided pigtail catheter insertion, fibrinolytic therapy, serial ultrasonographic evaluation, catheter manipulations as necessary (revision, exchange, or upsizing), and appropriate antibiotherapy. All patients were followed up at least 6 months. RESULTS: Technical success rate was 100%. Unilateral single, unilateral double, and bilateral catheter insertions were performed in 73, 9, and 2 patients, respectively. Inserted catheter sizes ranged from 8 F to 16 F. Streptokinase, urokinase, and tissue plasminogen activator were used as fibrinolytic agent in 29 (34%), 14 (17%), and 41 (49%) patients, respectively. In order to maintain effective drainage, 42 additional procedures (catheter exchange, revision, reposition, or additional catheter placement) were performed in 20 patients (24%). Clinical success was achieved in 83 of 84 patients (99%). Median catheter duration was 8 days (4-32 days). Median hospital stay during percutaneous management was 11.5 days (7-45 days). Factors affecting the median catheter duration were the presence of necrotizing pneumonia (p < 0.001) and bronchopleural fistulae (p < 0.001). CONCLUSION: Percutaneous imaging-guided catheterization with fibrinolytic therapy should be the method of choice in pediatric complicated PPE and empyema patients with surgical tube thoracostomy failure. Percutaneous treatment is useful in avoiding more aggressive surgical options.

Three-dimensional ultrasonographic evaluation of carotid artery plaque surface irregularity.

INTRODUCTION: The aim of this study was to evaluate 3-dimensional (3D) ultrasonography (US) in determining the surface irregularity of carotid artery plaques. MATERIAL AND METHODS: This study included 50 patients (20 females and 30 males) aged between 56 and 82 years with plaques in the carotid artery which were detected during routine neck ultrasound. Simultaneously these cases were evaluated in terms of plaque echogenicities and surface characteristics with 2D and 3D US. RESULTS: 3D imaging was successfully performed in 45 of the 50 cases and the technical success rate was 90%. A single plaque was detected in 64.4% of the patients, with the remaining 35.6% having more than one plaque. The lengths of the plaques ranged from 2 to 12 mm (mean: 3.98 ±1.70 mm); the widths ranged from 1.8 to 3.2 mm (mean: 2.11 ±0.37 mm). No significant difference was found between 2D and 3D plaque echo-structures (observer 1, p = 0.317; observer 2, p = 0.276), but there were significant differences between 2D and 3D plaque surface irregularities (observer 1, p = 0.002; observer 2, p = 0.004). The inter-observer agreement on 2D and 3D plaque echo-structure and surface irregularity was very good (k coefficients were 0.89 and 0.83, respectively, for echo-structure, and 0.91 and 0.95, respectively, for surface irregularity). CONCLUSIONS: The present study shows that 3D US examination is a valuable non-invasive method for investigation of surface irregularity of carotid artery plaques.

Efficacy of Staple Line Reinforcement With Omentopexy During Laparoscopic Sleeve Gastrectomy on Postoperative Complications: Experience of a Single Center.

BACKGROUND: The aim of this study was to evaluate the protective effects of staple line reinforcement with omentopexy during laparoscopic sleeve gastrectomy on postoperative complications. MATERIALS AND METHODS: A total of 3942 laparoscopic sleeve gastrectomy cases were included in the study. All the patients were divided into 3 groups: No reinforcement (NoSLR), staple line reinforcement with fibrin glue (SLR-FG), and staple line reinforcement with omentopexy (SLR-O). Demographic data and perioperative characteristics of the groups were analyzed retrospectively. Among these, age, sex, preoperative comorbidities, American Society of Anesthesiologists scores, body mass index, duration of operation, reoperation, complications, and Clavien-Dindo classification scores were recorded. RESULTS: Age, sex, body mass index, comorbid diseases, American Society of Anesthesiologists, and Clavien-Dindo Classification scores were similar in all the groups. The overall complication rate was 3.0%. The overall minor and major complication rates were 1.7% and 1.3%, respectively. The mortality rate was 0.1% (4 patients). The most common postoperative complications were bleeding (0.9%) and leakage (0.5%). The incidence of leakage, bleeding, and twisted gastric sleeve rates were similar when compared between SLR-FG and NoSLR. In the SLR-O patients, the incidence of leakage, hemorrhage, and twist were significantly lower and the operation time was significantly longer when compared with the other groups. CONCLUSIONS: The SLR-O technique, especially when performed by experienced surgeons, is a promising method for the prevention of postoperative leakage, bleeding, and twist complications with an acceptable increase in the duration of operation. Considering the limited effects of the SLR-FG technique, it was predicted that it would lose its popularity over time.

Investigating a correlation between the results of transcranial Doppler and the level of nerve growth factor in cerebrospinal fluid of hydrocephalic infants: clinical study.

OBJECTIVE: In this study, the correlation between the level of nerve growth factor (NGF) in cerebrospinal fluid (CSF) and transcranial Doppler (TCD) results has been investigated during preoperative and postoperative periods of hydrocephalic infants. METHODS: In the study, 27 patients (11 males and 16 females, aged 0-6 months) with congenital hydrocephalus were studied. CSF levels were obtained from the patients preoperatively and on postoperative days 3 and 30, and TCD was applied. The level of NGF was investigated in CSF by the ELISA method. The pulsatility index (PI) and resistive index (RI) were examined in the right middle cerebral artery by TCD. RESULTS: The mean NGF level (0.27 +/- 0.48 ng/ml) on the 3rd (NGF3) postoperative day was observed to be higher than the preoperative mean NGF level (NGF0; 0.15 +/- 0.16 ng/ml; p < 0.05). The mean NGF level on postoperative day 30 (NGF30; 0.13 +/- 0.13 ng/ml) was lower than the mean NGF3 level (p < 0.05). While the mean PI value on postoperative day 30 (PI30; 1.06 +/- 0.068) was observed to decrease compared to the preoperative PI (PI0; 1.26 +/- 0.83) and the PI on postoperative day 3 (PI3; 1.09 +/- 0.063), the mean PI3 value exhibited a drop compared to the PI0 value (p < 0.05). Whereas the mean RI value on postoperative day 30 (RI30; 0.63 +/- 0.023) showed a decrease compared to both preoperative mean RI (RI0; 0.70 +/- 0.025) and RI on postoperative day 3 (RI3; 0.65 +/- 0.021), RI3 displayed a drop compared to RI0 (p < 0.05). CONCLUSION: In this study, no correlation was determined between preoperative and postoperative NGF levels and preoperative and postoperative RI and PI values obtained from TCD examination. However, a positive correlation was found between the following results: preoperative PI and preoperative RI (r = 0.848); PI on postoperative day 3 and RI on postoperative day 3 (r = 0.690), and PI on postoperative day 30 and RI on postoperative day 30 (r = 0.707).

Imaging of sacroiliac joints in patients with acromegaly.

Acromegaly can lead to structural alterations of joints and bones. Patients with acromegaly may, therefore, have musculoskeletal complaints. In this study, sacroiliac joints are investigated in patients with acromegaly. 33 patients with acromegaly were enrolled. Sacroiliac joints were examined by X-ray and magnetic resonance imaging (MRI). In acromegaly, sacroiliac joints were abnormal in 36% of the patients by X-ray and 12.1% by MRI. When current axial spondylarthritis (SpA) classification criteria were taken into account, 6.1% of acromegaly patients could be classified as non-radiographic axial SpA and 2% as radiographic axial SpA. Sacroiliac joints are frequently affected in acromegaly and thus this disorder mimics the features of AS and SpA. Acromegaly should be kept in mind in the differential diagnosis of AS and SpA.

Grape seed extract supplement increases bone callus formation and mechanical strength: an animal study.

BACKGROUND: The positive effects of grape seed proanthocyanidin extract (GSPE) on bone health, which is a potent antioxidant, are known but its effects on fracture healing are not sufficiently covered in the literature. This study aims to investigate the effects of GSPE on fracture healing and biomechanics of healing bone. MATERIALS AND METHODS: Sixty-four adult Wistar-Albino male rats were divided into 8 groups of 8 animals in each group. Osteotomy was performed to the right femurs of all groups except the negative control (G1) and positive control (G2) groups, and intramedullary Kirchner wire was used for fixation. GSPE was given to half of the rats (G2-G4-G6-G8) 100 mg/kg/day by oral gavage. The rats were sacrificed on the tenth (G3-G4), twentieth (G5-G6), and thirtieth (G1-G2-G7-G8) days, respectively, and histopathological, radiological, and biomechanical examinations were performed. RESULTS: Histopathological examination of the specimens from the callus tissues revealed that bone healing was more prominent in the groups supplemented with GSPE (G4, G6, G8). There was a statistically significant improvement in radiological recovery scores and callus volumes in groups with GSPE. When biomechanical strengths were evaluated, it was found that GSPE increased bone strength not only in fracture groups but also in the positive control group (G2). CONCLUSIONS: As a result, this study showed that GSPE, a potent anti-oxidant, had a positive effect on bone healing and improved mechanical strength of the healing bone.

Median arcuate ligament syndrome during pancreaticoduodenectomy.

Median arcuate ligament syndrome is caused by the compression of the celiac artery by a fibrous band called the median ligament, which originates from the crus of diaphragm. The prevalence of Median arcuate ligament syndrome has been reported as 10%-24% among patients; however, the etiology is unclear. The components of the clinical triad include a chronic post-prandial pain, epigastric murmur, and weight loss. Diagnosis is based on clinical and radiological findings. Median arcuate ligament syndrome has been reported in a small portion of patients undergoing pancreaticoduodenectomy. Most patients have been diagnosed prior to surgery.
