Acute pancreatitis is an important cause of acute abdominal pain in children and requires prompt treatment because it may become life-threatening. The incidence of acute pediatric pancreatitis is increasing. Although epidemiology of acute pancreatitis, clinical manifestations and acute pancreatitis course in children are generally different than in adults, information about etiology, management and results are obtained on the basis of adult studies. In most cases, inflammation may limit itself, but in some cases acute pancreatitis, acute recurrent pancreatitis or chronic pancreatitis may progress. It is necessary to provide optimal management in the acute period of pancreatitis in children, as this may prevent secondary conplications. In this review we summarise the epidemiology of acute pancreatitis, role of imaging and imaging findings in the diagnosis of acute pancreatitis, treatment methods and management and complications of acute pancreatitis.

Aim

The decision to start treatment in sarcoidosis is made based on clinical and radiological findings and changes in pulmonary function test findings during follow-up, and more useful tools are needed in treatment management. F-18 fluorodeoxyglucose (18F-FDG) positron required important tomography / computed tomography (PET/CT) contains important information about the extent of sarcoidosis. On the other hand, the neutrophil/lymphocyte ratio (NLR) opens as a good prognostic marker for tissue-related inflammation. This study evaluated the relationship between the 18F-FDG PET/CT findings of sarcoidosis and NLR and other clinical findings.

Material and methods

The data of the patient who was diagnosed with sarcoidosis after 18F-FDG PET/CT examination in our clinic were retrospectively reviewed. Patients' age, gender, NLR values, smoking status, extrathoracic involvement and symptoms, and 18F-FDG PET/CT findings were compared.

Results

This study consisted of 41 patients. There was a strong correlation between NLR and whole body total lesion glycolysis (TLG), and moderate correlation between  MAIA and NLR (r values: 0.852, 0.660, both of them p value: <0.001, respectively). There was a significant difference between the groups showing only thoracic involvement and additional extrathoracic involvement with MAIA, TLG and NLR values (p values,: 0.002, 0.001 and, 0.003, respectively). In the classification made according to the symptoms of the patients, there was no significant difference between the groups with SUVmax, MAIA, TLG and NLR values. Median values were found to be significantly higher in the elderly group (p values: 0.037 and 0.040, respectively). In the classification made according to gender; there was no significant difference in both PET/CT parameters and NLR values.

Conclusion

The close relationship between the NLR value, which is accepted as a prognostic indicator in sarcoidosis, and the 18F-FDG PET / CT findings which show the involvement of the disease in the whole body, may provide the clinician with significant benefits in treatment management.

Aim: We aimed to evaluate the relationship between magnetic resonance (MR) enterography and diffusion magnetic resonance imaging (MRI) investigations in inflammatory bowel disease (IBD) patients during active inflammation and remission phases. 

Patients and Methods: We included patients diagnosed with IBD between 01.12.2015-31.08.2016 at our hospital. 47 patients were included; 30 were male (63.8%) and 17 were female (36.2%). Thirty two (68.1%) of them had ulcerative colitis and 15 (31.9%) had Crohn’s disease. Standard institutional sequences for upper and lower abdomen scan included: sagittal and axial T2 TRUFI, axial and coronal fat suppressed T2 TRUFI and coronal and axial T1 VIBE following intravenous (at 60 seconds) contrast medium administration. First group of patients (n=10) had MRI investigations both at active and remission phases, whereas in the second group of patients (n=37) apparent diffusion coefficient (ADC) values, bowel wall thickness and contrast enhancement grades were compared between actively inflamed and non-inflamed bowel segments.

Results: A statistically significant difference was found regarding ADC values and bowel wall thickness measurements in the first group of patients when compared between active and remission phase MRI investigations (p=0.005). Bowel wall contrast enhancement degree did not differ between active and remission phases in the first group (p=0.059). In the second group, there was a statistically significant difference between active and normal bowel segments regarding ADC values, bowel wall thickness and contrast enhancement (p<0.001).

Conclusion: MR enterography and diffusion MRI may be beneficial to determine the degree of inflammation and response to treatment in IBD patients.

Familial Mediterranean Fever (FMF) is characterized by attacks and inflammation of serous membranes. After discovery of MEVF mutations, several studies have been carried out about the effect of genotype to phenotype, a number of them showed relationship between genotype and phenotype, but some of them not. The aim of our study was to investigate the relationship between genotype and clinical features in children with FMF. This study was performed with 131 patients who have FMF diagnosis. The demographic data, clinical findings, mutations were investigated retrospectively. 52.7% of our patients were boys, 47.3% were girls. Distribution of the age of diagnosed was different from age of onset of symptoms (p=0.00). The most frequent symptom was abdominal pain (94.7%) and it is followed by fever (91.6%), arthralgia (65.6%) and chest pain (27.5%). Infection, stress, menstruation and physical training triggered the attack in some patients. Respectively, the most common mutations were M694V (50.4%), M680I (26.7%) and 148Q (11.5%). No mutation was detected in 14.5% of our patients. Nausea and vomiting were less in M694V homozygous patients, and arthralgia was higher in E148Q heterozygous patients (p<0.05). We had 3 patients with colchicine-resistant who were siblings. In our study, a significant relationship between phenotype and genotype was not observed. It is difficult to recognize the disease in infancy period, FMF should be considered in patients with frequently admitted to hospital in order to avoid complications.

The prevelans of prediabetes is increasing over the world. It is estimated that more than 470 million people will have prediabetes by 2030. Prediabetes is defined as intermediate state between normal and diabetic glycaemic values and high risk categories for DM development. Insulin resistance and beta cell dysfuction start with prediabet before marked glucose changes. In observational studies it has been reported that the relationship was found between prediabetes and chronic renal disease, small fiber neuropathy, retinopathy, serebrovascular and cardiovascular disesase. In this review, it was evaluated that the definition of prediabetes and its microvascular and macrovascular complications.

Demonstrating the imaging findings of asymptomatic giant thymolipoma mimicking cardiomegaly is aimed. A paracardiac mass was detected with 32-year-old male patient afterwards demonstration of cardiomegaly on a posterior-anterior (PA) chest x-ray examination taken for a routine control. Computed tomography (CT) showed a mass, localized in the anterior mediastinum, with smooth margins, showing no significant invasion of adjacent structures, and including fat density with fibrous component. The diagnosis was reported as thymolipoma histopathologically after transthoracic biopsy. On a preoperative magnetic resonance (MR) examination, taken for detailing the limits of the lesion, the mass showed hyperintensity on both T1 and T2 weighted images, and suppression on fat saturated T2 weighted images. No invasion of adjacent structures was detected. A thymolipoma may reach a large size without symptoms due to its great pliability. It can mimic cardiomegaly on x-ray images. Adipose tissue on CT is helpful in the diagnosis. MRI gives valuable information in determining the exact boundaries of the lesion.

Mesenteric panniculitis is a situation which effects adipose tissue of the mesentery with inflammation and fibrosis. There may be symptoms like stomachache, nausea, vomiting or asymptomatic. Trauma, abdominal surgery, infection are the main causes and recently its association with the malignancy has been increased. We reported asymptomatic mesenteric panniculitis in a patient with chronic lymphocytic leukemia that hasn’t been experienced before in the literature.

Aim: Bullous pemphigoid (BP) is a bullous dermatosis frequently seen in advanced age that is caused by antibodies reacting to antigens in the dermoepidermal junction. It has been reported that as a result of autoantibody-induced inflammation, inflammatory mediators are increased in patient sera and bullae, and that these increased mediators might be related to disease severity. Neutrophil lymphocyte ratio (NLR) is determined by dividing the number of neutrophils by the number of lymphocytes; it is a parameter that has been previously studied in inflammatory diseases such as urticaria, psoriasis, pemphigus vulgaris and cutaneous vasculitis and has been associated with the disease. The present study investigated the utility of NLR, the marker of systemic inflammation, as a marker in patients with BP. Patients and Methods: Medical records of patients diagnosed with BP between January 2013 and December 2017 were reviewed. By evaluating the laboratory results in their files, the mean platelet volume (MPV), neutrophil count, lymphocyte count, and neutrophil lymphocyte ratio calculated by dividing the number of neutrophils by the number of lymphocytes were recorded. Results: The study included 26 patients with BP and 25 control patients. Neutrophil count (P = 0.005) and NLR (P = 0.04) were found to be higher in patients with BP compared with the control group. No difference was found in lymphocyte count and MPV between the groups. Conclusion: To our knowledge, this is the first study to investigate NLR in patients with BP in the etiopathogenesis of which inflammation takes a part. We believe that NLR, a parameter that can be easily calculated by a whole blood count for systemic inflammation, can be a marker that can be used in the diagnosis of BP.

To investigate the level of 25(OH)D and association between 25(OH)D level and hormonal-biochemical parameters in Polycystic ovary syndrome (PCOS). Thirty three patients diagnosed with PCOS and 42 age- body mass index (BMI) matched control group admitted to Bolge Training and Research Hospital from May to October were included in the study. Serum total testosterone (TT), free testosterone (fT), 25(OH)D, dihydroepiandrostenodione sulphate, LH, FSH, thyroid stimulating hormone (TSH), cortisol, 17αOH-progesterone, fasting glucose, insulin levels were evaluated after 12 hour fasting. HOMA-IR (fasting glucose level x fasting insülin / 405) was calculated. Serum 17αOH progesterone and 25(OH)D levels were significantly lower in PCOS group (p<0.01). Serum LH, LH/ FSH TT, FT, insulin, ACTH, and DHEAS levels were significantly higher in PCOS group (p<0.01). There was statistically significant negative correlation of 25(OH)D levels with PCOS, LH/FSH, TT, fT, DHEAS ve FGS. There was no statistically significant correlation between 25(OH)D levels and age, body mass index and insulin resistance. The results of this study indicated that vitamin D deficiency is highly prevalent among women with PCOS independent of body mass index. We also demonstrated that vitamin D deficiency was correlated with hyperandrogenism in PCOS women. Low serum 25(OH)D levels might exacerbate PCOS symptoms. Large intervention trials are needed to evaluate the effect of vitamin D supplementation on hormonal and clinical parameters in PCOS women.

Chronic otitis media and mastoiditis are the result of infection by an organism of low virulence or of acute infection with incomplete resolution. Mastoid inflammation produces thickening of some trabeculae secondary to reactive new bone formation and at the same time mineralization of other trabeculae. A cholesteatoma is an epidermoid cyst that consists histologicaly of an iner layer of stratified squamous epithelium. The lumen of the cyst is filled with desquamated epithelial debris. As the cyst enlarges and comes into contact with contigious bony structures of the middle ear, mastoid and petrous pyramid, erosion of these structures occurs owing to pressure necrosis and enzymatic lysis of bone. Ossicular erosion is seen %70 ratio. Ossicular erosion is seen later and the long crus of incus is eroded the most frequently. But the bigger lesions may make erosion whole ossicles. Cholesteatomas may make tegmen erosion, mastoid cortex irregularity, fasial nevre contour irregularity and semisircular canal defect according to bigness and period. Tympanosclerosis develops in the result of collecting hyalin and calsific deposits in tympanic membran and the submucosa of middle ear. These are tympanosclerotic plugs. It appears in the result of otitis media or trauma.

Introduction: Circulating stem cells (CSCs) are released from bone marrow in to the circulation after myocardial injury to improve tissue repair. Radiofrequency ablation (RFA) of cardiac arrhythmias, particularly for atrial fibrillation, has been shown to trigger the release of CSCs through inflammatory mediators. We aimed to investigate whether CSCs are increased in the circulation following non-extensive ablation procedures such as slow pathway or accessory pathway ablations.

Methods: Twenty-six patients [13 females, 54 (18-74) years old] who underwent slow pathway ablation for atrioventricular nodal reentrant tachycardia (n=18) and accessory pathway ablation for atrioventricular reentrant tachycardia (n=8) were included. Peripheral blood CD34+ cell count and multiple serologic markers [troponin I (Tn-I), C-reactive protein (CRP), interleukin-6 (IL-6), stromal cell derived factor (SDF) 1 alpha] were evaluated before the ablation procedure and 7 and 30 days after the procedure.

Results: The CD34+ cell count was significantly increased on the 7^th day after the procedure when compared to baseline [33 (15-133) vs. 22,5 (5-79) cells per microliter respectively, P<0.001]. The CD34+ cell count was similar to baseline on the 30^th day following the procedure. Levels of Tn-I, CRP, IL-6 and SDF1-α did not change significantly following ablation. The amount of energy applied during RFA (watts) was significantly correlated with the 30^th day CD34+ cell count (r: 0.460; p= 0.018).

Conclusions: Peripheral blood CSCs are increased after slow pathway or accessory pathway ablations which are less extensive ablations compared to atrial fibrillation ablation. The levels return to baseline by the 30^th day following the procedure. The increase in CSCs was positively correlated with the amount of energy delivered during the procedure.
