A novel technique for thulium laser enucleation of the prostate: anterior releasing with ThuLEP (ARTh technique).

Thulium laser enucleation of the prostate (ThuLEP) is a highly effective approach to the treatment of benign prostatic hyperplasia. We present here a description of the "ARTh Technique" and the benefits it offers in terms of improved visualization, short operation times, and easy recognition of the dissection plane, describing specifically the anterior release (AR) technique using ThuLEP(Th). Included in this retrospective study were 32 consecutive patients operated on between January 2022-November 2022. Parameters were measured before and after the procedure: the International Prostate Symptom Score(IPSS), maximum flow rate(Qmax), post-void residual urine(PVR) prostate-specific antigen(PSA), prostate volume, operation-time, morcellation-time, catheterization-time and presence of transient urinary incontinence, and compared. The median age of patients undergoing enucleation of the prostate using the ARTh technique was 64 years (range: 44-83). The median prostate volume of the patients was 83.5 ml(50-128 ml), preoperative-IPSS was 24.8(15-33), postoperative-IPSS was 7(5-11), preoperative-Qmax was 8.1 ml/Sects. (5-11.5 ml/sec), postoperative-Qmax was 26.9 ml/Sect. (20.8-34 ml/sec), preoperative-PVR was 145 ml(75-258 ml), postoperative-PVR was 36.2 ml(0-66 ml), total operation time was 51.4 min(28-82 min), enucleation time was 36.9 min(19-51 min) and morcellation time was 15.3 min(8-27 min). The ARTh technique is a safe procedure that allows the surgeon to easily recognize and adhere to the defined dissection plane, thus decreasing operation times, significantly reducing the rate of postoperative transient urinary incontinence (TUI).

Role of 18F-fluorodeoxyglucose positron-emission tomography/computed tomography in restaging of adrenocortical carcinoma.

Background: The objective was to retrospectively evaluate the contribution of fluorodeoxyglucose [18F] positron emission tomography/computed tomography (18FDG-PET/CT) to the re-staging of adrenocortical carcinoma (ACC). Materials and methods: A total of 16 patients (10 males and 6 females), who underwent adrenalectomy due to adrenocortical carcinoma and 18FDG-PET/CT scan to re-stage the tumor between July 2007 and April 2013, were included in the present study. The mean age was 53.37 ± 13.91 years (min: 30, max: 74) The patients were required to fast for six hours prior to scanning, and whole-body PET scanning from the skull base to the upper thighs was performed approximately 1 h after the intravenous injection of 555 MBq of F-18 FDG. Whole body CT scanning was performed in the cranio-caudal direction. FDG-PET images were reconstructed using CT data for attenuation correction. Suspicious recurrent or metastatic lesions were confirmed by histopathology or clinical follow-up. Results: Sensitivity, specificity, positive predictive value, negative predictive value and accuracy of 18FDG-PET/CT were 100%, 83.3%, 90.9%, 83.3%, and 93.7%, respectively. Conclusion: 18FDG-PET/CT detects local recurrence and/or distant metastases with high accuracy in the re-staging of operated adrenocortical carcinoma. It is considered that the procedure could play an important role in treatment decision after the operation and post-operative follow-up and could influence the entire decision-making process.

The clinical features and the factors affecting visual prognosis in pediatric open-globe injuries.

PURPOSE: To investigate clinical features and factors affecting visual prognosis after pediatric open-globe injuries. METHODS: Retrospective study of 223 children with open-globe injury was conducted. Children with final logMAR visual acuity (LVA) > 0.70 were determined as poor-vision group (group 1, n = 108) and those with final LVA ≤ 0.70 as good-vision group (group 2, n = 115). Demographic characteristics (age, gender, and damaged eye), time between trauma and surgery, ocular trauma score (OTS), follow-up time, injury size, initial and final visual acuity levels, injury type (penetrating injury, globe rupture, perforating injury, and intraocular foreign body injury), injury localization (zone 1 = within the corneal and/or limbal area, zone 2 = within the scleral area extending 5 mm back from the limbus, and zone 3 = within the area posterior to zone 2), injury cause [metal objects (fork, knife, needle), broken glass, blunt objects (ball, punch), pen-pencil, and unidentified objects], and accompanying ocular findings of the groups were detected, and comparisons were done. Additionally, effects of age, time between trauma and surgery, OTS, injury size, follow-up time, initial LVA, injury type, and injury zone on final LVA were analyzed in both groups. RESULTS: Mean age was 9.1 ± 2.0 years. There were 151 males and 72 females. Compared to group 1, group 2 had better initial and final visions (1.21 ± 0.26 vs 0.60 ± 0.28, p < 0.001 for initial LVA; 1.00 ± 0.32 vs 0.30 ± 0.13, p < 0.001 for final LVA), greater OTS (1.72 ± 0.53 vs 3.73 ± 0.61, p = 0.025), and smaller injury size (10.4 ± 3.5 vs 5.8 ± 2.4 mm, p = 0.002). Globe rupture (p = 0.015) and relative afferent pupillary defect (RAPD) (p = 0.037) were higher in group 1, while penetrating injury (p = 0.044), zone 1 involvement (p = 0.038), and metal object injury (p = 0.041) were higher in group 2. Based on multivariate analysis, the presences of globe rupture (p = 0.024) and RAPD (p = 0.035), the involvement without zone 1 (p = 0.042), and the injury without metal object (fork, knife, needle) (p = 0.046) were associated with poor final vision. Final LVA (for group 1 and group 2) was negatively correlated with OTS (r = - 0.398, p = 0.037; r = - 0.369, p = 0.040), while positively correlated with injury size (r = 0.412, p = 0.031; r = 0.318, p = 0.046) and initial LVA (r = 0.335, p = 0.043; r = 0.402, p = 0.034). CONCLUSION: In our study, poor prognostic factors affecting final vision were low OTS, poor initial vision, the presences of globe rupture and RAPD, the large injury size, the involvement without zone 1, and the injury without metal object (fork, knife, needle).

Does the conjunctivochalasis accompanied by pseudoexfoliation syndrome affect the ocular surface and anterior segment structures?

PURPOSE: The probability of the coexistence of conjunctivochalasis and pseudoexfoliation syndrome (PES) in the same individual may increase with aging. We investigated the effects of conjunctivochalasis accompanied by PES on the ocular surface (OS) and anterior segment (AS) structures. METHODS: Cases with only conjunctivochalasis were determined as Group 1 (n = 62), cases with conjunctivochalasis accompanied by PES as Group 2 (n = 45), and healthy individuals as Group 3 (n = 56). The OS and AS parameters of the groups were compared. RESULTS: There were a higher grade-3 conjunctivochalasis rate (17.7% vs. 46.7%, p = 0.039), a greater "mean grade of conjunctivochalasis" value (1.72 ± 0.24 vs. 2.29 ± 0.32, p = 0.036), and a higher "total conjunctivochalasis score" (4.27 ± 1.13 vs. 6.12 ± 1.35, p = 0.025) in Group 2 than in Group 1. Additionally, Group 2 had a shorter tear film break-up time (TBUT) (9.17 ± 2.53 vs. 5.41 ± 1.32, p = 0.010) and a greater OS disease index (OSDI) score (16.28 ± 3.15 vs. 27.36 ± 4.12, p = 0.037) than Group 1. Moreover, both Group 1 and Group 2 had shorter TBUTs (Group 1-3: p = 0.004; Group 2-3: p < 0.001) and greater OSDI scores (Group 1-3: p = 0.042; Group 2-3: p = 0.019) compared to Group 3. The groups' ocular surface staining scores, Schirmer 1 tests, central corneal thicknesses, keratometries, axial lengths, anterior chamber depths, lens thicknesses, and intraocular pressures were similar (p > 0.05). CONCLUSIONS: To our knowledge, this was the first study comprehensively investigating the effects of conjunctivochalasis accompanied by PES on the OS and AS structures together. We found that conjunctivochalasis might cause the OS disease, while the presence of PES in conjunctivochalasis cases might worsen both the OS disease and conjunctivochalasis findings.

Primary Eosinophilic Gastrointestinal Diseases Beyond Eosinophilic Esophagitis in Children.

OBJECTIVES: There are many unknowns about primary eosinophilic gastrointestinal disease (EGID) in childhood. The aim of this study is to provide data about the frequency, management, control level, and prognosis of well documented primary EGID in childhood. METHODS: This study was conducted in children who underwent endoscopy and/or colonoscopy at a single center over 10-year period up to August 2018. Primary EGID was diagnosed after exclusion of secondary EGID and classified as eosinophilic gastritis (EG), eosinophilic enteritis (EE), eosinophilic gastroenteritis (EGE: eosinophilic gastritis with eosinophilic enteritis) and eosinophilic colitis (EC) according to histopathological evaluation. The pathological number of eosinophil counts were accepted as >30 hpf for gastric mucosa in 5 hpf area, ≥20/hpf for duodenal, jejunal, and ileal mucosa, >50/hpf for right colonic mucosa, >35/hpf for transverse colonic mucosa, and >25/hpf for left colonic mucosa. Presenting symptoms, signs, management, follow-up, disease control level, and remission were analyzed. Remission is defined if the patient is controlled with all clinical, endoscopic/colonoscopic, and histopathologic parameters without any treatments or diet for at least a year. RESULTS: During the study period, 7457 biopsies were taken in 8262 endoscopy and/or colonoscopy procedures. Primary and secondary EGID frequencies were found 0.23% (n = 17 patients) and 0.1% (n =8 patients) per procedure with biopsy in children, respectively. Endoscopy/colonoscopy procedures were not able to performed in 9 patients because of short follow-up period (n = 6) or patients leaving follow-up (n = 3). Nine of the primary EGID patients had esophageal eosinophilia (EsE) at the time of diagnosis, 5 of them were previously managed as EoE. The median follow-up period of primary EGID patients excluding the ones without a control endoscopy/colonoscopy procedure was 3.35 years (min-max: 1.1-9.0 years). Proton pump inhibitors (PPI) were the most frequently used treatment alone or in combination with diet, systemic and/or topical corticosteroids. Disease control was evaluated in 8 of 17 patients and it was uncontrolled in 4, partially controlled in 1, and controlled in 3 patients. Remission was achieved in 2 patients. CONCLUSIONS: The frequency of primary EGID beyond eosinophilic esophagitis (EoE) in children is low. It may be difficult to achieve control in children with primary EGID in the long-term follow-up.

New Findings of Immunodysregulation, Polyendocrinopathy, and Enteropathy X-linked Syndrome (IPEX); Granulomas in Lung and Duodenum.

Immune dysregulation, polyendocrinopathy and enteropathy, X-linked (IPEX) syndrome is a rare disorder caused by loss-of-function mutations in the gene forkhead box protein 3 (FOXP3). IPEX patients frequently show chronic diarrhea (enteropathy) associated with villous atrophies in the small intestine. Our case is different from this classical information in the literature, since he presented with neonatal onset inflammatory bowel disease within the first months of life accompanied by deep ulcers throughout colonic mucosa. Moreover, he developed chronic lung disease during follow-up and histopathological examinations showed granulomas in both gastrointestinal tract and lung parenchyma. Genetic analysis revealed the diagnosis of IPEX syndrome with a germline mutation in FOXP3. Thus, our study provides an unusual presentation of IPEX syndrome with colitis and granulomas presence in histopathological examinations.

Comparison of the effects of 180° and 360° applications of selective laser trabeculoplasty on intraocular pressure and cornea.

PURPOSE: To compare the effects of 180° and 360° selective laser trabeculoplasty (SLT) on intraocular pressure (IOP) and cornea in patients with bilateral primary open-angle glaucoma. METHODS: Fifty-two eyes of 26 patients were included. On the same day, 180° SLT (Group 1) was applied to one eye of patients and 360° SLT (Group 2) to the other eye. IOP values were compared at pre-SLT and post-SLT 1 day, 1 week, 1, 3, and 6 months. Changes in central corneal thickness (CCT) and endothelial cell count (ECC) were examined. RESULTS: In groups, significant decreases were observed in IOP at 1 week (p < 0.05), 1, 3, and 6 months (p < 0.001). No significant difference was determined between group 1 and 2 in IOP-lowering effectiveness or success rates (p > 0.05). There was no significant difference in CCT at inter- or intragroup comparisons (p > 0.05). In group 1, no significant difference was determined in pre- and post-SLT ECC (p > 0.05). In group 2, significant decrease in ECC was observed at 1 week (p < 0.05). However, ECC returned to its initial levels at 1 month. CONCLUSIONS: To the best of our knowledge, this is the first study in literature to compare different quadrant SLT applications performed on both eyes, on the same day, in the same patient group and to compare the effects of those applications on IOP and cornea. In reducing IOP, 180° and 360° SLT are similarly effective. These effects begin on the 1st week and persist for 6 months. Temporary corneal changes may be observed following 360° SLT.

Can ocular changes be detected early in children and adolescents with type 1 diabetes mellitus without retinopathy by using optical biometry and optical coherence tomography?

PURPOSE: To determine early ocular changes in children and adolescents with type 1 diabetes mellitus without retinopathy (T1DM-woR) by optical biometry (OB) and optical coherence tomography (OCT). METHODS: Seventy children and adolescents with T1DM-woR (patient group) and 72 healthy children and adolescents (control group) were included. Demographic data, anthropometric measurements and anterior-posterior segment parameters of groups were compared. Correlations between ocular parameters and glycosylated hemoglobin (HbA1c) level, age at diabetes mellitus (DM) onset and DM duration were evaluated. RESULTS: Patients with T1DM-woR had significantly shallower anterior chambers (3.50 ± 0.12 vs 3.67 ± 0.11 mm, p < 0.001), thicker lenses (3.65 ± 0.15 vs 3.37 ± 0.14 mm, p < 0.001), thinner central retinal nerve fiber layer (RNFL) thicknesses (95.3 ± 6.7 vs 104.8 ± 6.2 µm, p < 0.001) and thinner central choroidal thicknesses (292.8 ± 23.6 vs 325.1 ± 24.7 µm, p < 0.001) than healthy individuals. As the lens thickness (LT) increased, anterior chamber depth (ACD) decreased in patient group (r = - 0.368, p = 0.040). Other anterior (central corneal thickness, axial length, keratometry, spherical equivalent) and posterior (superior temporal, superior nasal, nasal, inferior nasal, inferior temporal, temporal RNFL thicknesses; nasal and temporal choroidal thicknesses; central part's and inner-outer macular segments' thickness and volume measurements) segment parameters of groups were similar (p > 0.05). In patient group, as HbA1c level increased, central RNFL and choroidal thicknesses decreased (r = - 0.639, p < 0.001; r = - 0.486, p = 0.010, respectively). CONCLUSIONS: In patients with T1DM, we found that LT increased, and ACD, central RNFL and choroidal thicknesses decreased by OB and OCT before visible findings appeared in routine ophthalmological examination. Determination of early changes is warning to physician and patient in order to prevent more serious damages occurring later.

Effects of commercial aldehydes from green leaf volatiles (green odour) on rumen microbial population and fermentation profile in an artificial rumen (Rusitec).

The effects of plant metabolites on rumen metabolism vary greatly depending on their antimicrobial spectrum and applied doses. In this study, the minimum inhibitory concentrations (MICs) of commercial aldehydes, trans-2-hexenal (T2H), cis-3-hexenal (C3H), trans-2-nonenal (T2N), and trans-2-decenal (T2D) from green leaf volatiles, were tested on rumen bacteria. These compounds were found more effective on Gram-positive rumen bacteria than the Gram-negatives, and C3H was the most effective compound. Then, for 14 days, the in vitro effects of C3H compared with monensin (5 mg/day) on the rumen microbial population and ruminal fermentation at 187.5, 375 and 750 mg/day doses were tested based on the MIC value (500 µg/mL) by using the rumen simulation technique (Rusitec). Supplementation with C3H at 375 mg/day increased the cell numbers of Butyrivibrio fibrisolvens significantly. The addition of C3H at 375 and 750 mg/day doses also increased Streptecoccus bovis cell counts. The use of monensin did not affect the cell numbers of these bacteria. On the other hand, C3H did not change the counts of total bacteria, methanogens, or hyper-ammonia-producing (HAP) bacteria like monensin. The numbers of Ruminococcus albus and Ruminococcus flavefaciens were also stable in the presence of C3H but decreased significantly with the addition of monensin (P < 0.05). Fibrobacter succinogenes, Megasphaera elsdenii, and Selenomonas ruminantium cell counts were not affected by either application. In addition, C3H increased the acetate and methane production along with the acetate-to-propionate ratio at all tested concentrations, unlike monensin. Supplementation with C3H decreased propionate production significantly, except at the 187.5 mg/day dose. Butyrate production increased (P < 0.05) only in the presence of 187.5 and 375 mg/day doses of C3H. Production of total volatile fatty acids (VFA) and dry matter digestibility (DMD) did not change in treatment groups. Also, the total protozoa numbers and ammonia-N concentrations significantly decreased (P < 0.05) in C3H-treated samples, similar to monensin. Although C3H did not have favorable effects on energy efficiency, it suppressed rumen protozoa and mitigated rumen ammonia without adversely effecting ruminal fermentation in all applied doses. Based on the result, C3H has the potential to improve protein utilization in the rumen.

An alternative endoscopic portal for suprascapular nerve approach: an anatomic study.

PURPOSE: Arthroscopic approaches have been less preferred than open techniques for treating suprascapular nerve entrapment, possibly because current arthroscopic portals are based on distances to reference points, resulting in discrepancies from differing shoulder sizes. This study reports a portal placement based on proportions rather than absolute length. METHODS: Open dissection (12 left shoulders) and arthroscopy (12 contralateral shoulders) of the suprascapular notch were performed. In left shoulders, the posterolateral prominence of the acromion, the T1 spinous process, and the suprascapular notch were marked (K-wires). Distances from the posterolateral prominence of the acromion to the suprascapular notch and to the T1 spinous process were measured, and the proportion of those distances (distance to the suprascapular notch/distance to the T1 spinous process) was calculated to indicate the portal's location. In right shoulders, arthroscopy anatomically assessed that proportion's reliability. RESULTS: Median distances from the posterolateral prominence of the acromion to the T1 spinous process and to the suprascapular notch were 175.7 mm (average 180.4, SD 11.8 mm) and 72.3 mm (average 73.9, SD 4.9), respectively. The medians of the proportions of the defined distances were 40.9 % (range 40-42 %) and 41 % (range 39.3-42.1 %), respectively. CONCLUSION: Locating the portal at the lateral, 41 % of the distance between the posterolateral prominence of the acromion and the T1 spinous process was accurate and reproducible for suprascapular notch visualization. Clinically, this portal seems to eliminate perioperative morbidity by reducing excessive soft-tissue dissection with a shorter arthroscopic route and avoiding the ligamentous damage.

High-grade Primary Renal Leiomyosarcoma.

OBJECTIVE: To investigate the clinical characteristics, prognosis, survival and diagnosis of high-grade primary renal leiomyosarcoma. MATERIALS AND METHODS: From January 2003 to April 2013, 10 cases of high-grade primary renal leiomyosarcoma were retrospectively reviewed. We analyzed clinical manifestations, treatment and prognosis of our group and correlated to the literature. RESULTS: Ten cases (five male and five female patients; age range 43-77 years, mean = 57 ± std d:12.3 ) were enrolled. The mean diameter of the tumor masses was 9.35 ± 4.5 cm (range 3-18 cm). 40% of the patients were asymptomatic while the major symptom of 60% patients was lumbar pain. Nephrectomy was performed in 90% of patients. Partial nephrectomy surgery was preferred for only one patient. Pleomorphism and necrosis with high-grade, pink spindle cell cytoplasm were viewed in all patients. All patients were high-grade, pink spindle cell cytoplasm and pleomorfism and necrosis were observed in all. In an immunohistochemical examination, vimentin was seen in 100%, desmin in 90% and smooth muscle actin in 80% of the patients. CD117 was negative in all patients. All of the cases were followed-up, and the time of survival varied from 6 to 68 months (mean 23.9 ± std d:20.1). No patient received adjuvant CTx and/or RTx. CONCLUSION: High-grade primary renal leiomyosarcomas (LMSs) are rare and highly malignant and the prognosis is poor. Early diagnosis and radical nephrectomy can prolong the patient's life. Surgery is the main treatment modality for renal (leiomyosarcoma) LMS.

Effect of microorganisms on etiology of hematospermia.

BACKGROUND: Hematospermia is the presence of blood in the ejaculate. Its etiology is congenital, inflammatory, infectious, obstructive, tumoral, vascular, traumatic, iatrogenic or related to systemic disease. It is a quite irritating and life-quality-disturbing condition for men. It is significant to demonstrate infectious-based hematospermia due to the fact that its treatment is easier than for other reasons. METHODS: 30 patients, having spontaneous hematospermia, were taken to our study. The serum total PSA levels of the patients were examined and microbiological examinations such as direct inspection for ejaculate, routine bacteriological and mycetes culture, Gram staining, trichrome staining and Mycoplasma hominis/Ureaplasma urealyticum culture (Mycofast Evolution 3, ELITech, France) were performed. RESULTS: Bacteria was isolated in 11 (36%) of 30 patients with hematospermia. S.aureus occurred in five patients (45.5%), U.urealyticum in three patients (27.2%) and E.coli and K.pneumoniae in one each (9.1%). U.urealyticum and S.aureus occurred together in one patient. No statistical difference of scores of National Institute of Health-Chronic Prostatitis Symptoms Index (CPSI) and serum total PSA levels between the patients with and without infection was observed. CONCLUSIONS: Hematospermia mostly affects micturition functions of young men and it can be due to infection in one-third of the cases.

A rare combination of vascular variations of both kidneys.

Bilateral variations of renal vessels were encountered during the dissection of a 54-year-old male cadaver. There were triple renal arteries bilaterally, double renal veins on the right, and an unusual formation of renal vein on the left side. A bilateral occurrence of triple renal arteries has not been encountered in the literature, so does an incidence. Additional renal vessels have the potential to cause clinical complications such as hydronephrosis. Their existence has utmost importance in surgical and radiological interventions and radiological examinations.

The association of pre-photorefractive keratectomy Schirmer-1 test value with postoperative corneal epithelial thickness, ocular surface discomfort, and visual acuity.

PURPOSE: To investigate the association of pre-photorefractive keratectomy Schirmer-1 test value with post-photorefractive keratectomy central corneal epithelial thickness, ocular surface disease index score, and uncorrected distance visual acuity. METHODS: Patients were categorized according to preoperative Schirmer-1 value: the normal Schirmer Group (n=54; Schirmer-1 test value, >10 mm) and the low Schirmer Group (n=52; Schirmer-1 test value, between 6 and 10 mm). We analyzed ablation depth, visual acuity, result of Schirmer-1 test (with anesthesia), tear film break-up time, ocular surface disease index score, central corneal epithelial thickness, and spherical equivalent refraction. RESULTS: We found significant differences between the groups in Schirmer-1 test value, tear film break-up time, and ocular surface disease index score, both preoperatively and postoperatively (p<0.001). The preoperative central corneal epithelial thicknesses of the two groups were similar (p>0.05). After photorefractive keratectomy, the Schirmer-1 test value and spherical equivalent refraction decreased in both groups (p<0.05), and ocular surface disease index scores and central corneal epithelial thickness values increased in the low Schirmer Group (p<0.001) but not in the normal Schirmer Group (p>0.05). The postoperative central corneal epithelial thicknesses of the low Schirmer Group were significantly higher than those of the normal Schirmer Group (p<0.001). Postoperative uncorrected distance visual acuity did not differ significantly between the two groups (p>0.05). CONCLUSIONS: In patients with low Schirmer-1 test values before photorefractive keratectomy, the corneal epithelium thickened and ocular surface complaints increased during the postoperative period. However, changes in the corneal epithelium did not affect the postoperative uncorrected distance visual acuity. To reduce postoperative problems on the ocular surface in these patients, we recommend that dry eye be treated before photorefractive keratectomy.

The relationship between dietary inflammatory index scores and rheumatoid arthritis disease activity.

INTRODUCTION: Many patients diagnosed with rheumatoid arthritis (RA) report relief of symptoms after consuming certain foods. Diet plays a vital role in rheumatoid arthritis-related inflammation regulation. This study investigates the relationship between dietary inflammation index (DII) scores and RA disease activity. MATERIALS AND METHODS: Forty-one RA patients were enrolled in the study. The general inflammatory index of the diet was analyzed by recording the 24-h food consumption of the patients, and the nutrients were analyzed using the Nutrition Information Systems Package Program. Dietary inflammatory indices were calculated for each patient using the patients' macro and micronutrient intake levels. RA disease activity was assessed using the Disease Activity Score-28 (DAS-28). RESULTS: The DAS-28 score was lower in the anti-inflammatory diet group compared to the pro-inflammatory diet group (p=0.163). A weak but significant relationship was found between diet inflammation index score and DAS-28 (r=0.3468, p=0.0263). The effect of the dietary inflammatory index on the DAS-28 was 12.02%. Dietary iron, vitamin C, niacin, and magnesium intakes were statistically significantly higher in the quartile group that received an anti-inflammatory diet than in the quartile group that received a pro-inflammatory diet. The intake of some micronutrients, such as iron, zinc, magnesium, and folic acid, was significantly lower than the recommended values in all RA quartile groups. CONCLUSION: Our results suggest that reducing inflammation through the diet may have a weak but significant effect in controlling disease activity in RA patients.

Clinicopathological significance of mutation profile detected by next generation sequencing in different metastatic organs of non-small cell lung cancers.

BACKGROUND: The primary tumor and it's metastases show heterogeneity in molecular studies for targeted therapies in Non-Small Cell Lung Cancer(NSCLC), the leading cause of cancer-related deaths worldwide. The study aimed to identify somatic mutations in biopsies from NSCLC patients' metastatic organs using Next-Generation Sequencing(NGS) and examine their association with clinicopathological parameters. MATERIALS AND METHODS: The study included 128 NSCLC patients and, NGS was performed on tumor biopsies from different metastatic organs at Molecular Pathology laboratory of the Department of Medical Pathology in Aydin Adnan Menderes University Faculty of Medicine. The age, gender, histopathological diagnoses, metastatic organs, smoking and mutation status were all recorded, along with the analysis results of 72 genes and 4149 primers in the panel of the NGS system. RESULTS: 53.9 % of the cases had a history of smoking and patients with brain metastases had a higher smoking rate(p=0.000). The most common occurrence(39.8 %) was lymph node metastasis, followed by brain(19.5 %). There was a strong correlation between mutation presence and metastasis in the liver(p=0.012), bone(p=0.002), and pleura(p=0.008). Smokers had a higher frequency of KRAS(p=0.000) and TP53(p=0.001) mutations. Brain metastases showed a statistically significant NF1 mutation(p=0.001), while the liver exhibited a significant BRAF mutation(p=0.000). NF1-TP53, PTEN-TP53 and NF1-PTEN were the most common concomitant mutations and, the brain was the most common metastatic organ in which they occurred. CONCLUSION: Our results suggest prizing assessing detected mutations, in the prediction, follow-up and management of metastases, especially in patients with lung adenocarcinoma. The assessment also needs to consider the tumor's mutation status in metastatic organs. New therapeutic agents targeting NF1 mutations will be available in the future to treat NSCLC, especially in metastases.

Evaluation of response to gemcitabine plus cisplatin-based chemotherapy using positron emission computed tomography for metastatic bladder cancer.

BACKGROUND: The purpose of the present study was to examine retrospectively the contribution of 18Fluorodeoxyglucose positron emission tomography computed tomography (18FDG-PET/CT) to the evaluation of response to first-line gemcitabine plus cisplatin-based chemotherapy in patients with metastatic bladder cancer. AIM: To evaluate the response to Gemcitabine plus Cisplatin -based chemotherapy using 18FDG-PET/CT imaging in patients with metastatic bladder cancer. METHODS: Between July 2007 and April 2019, 79 patients underwent 18FDG-PET/CT imaging with the diagnosis of Metastatic Bladder Carcinoma (M-BCa). A total of 42 patients (38 male, 4 female) were included in the study, and all had been administered Gemcitabine plus Cisplatin-based chemotherapy. After completion of the therapy, the patients underwent a repeat 18FDG-PET/CT scan and the results were compared with the PET/CT findings before chemotherapy according to European Organisation for the Research and treatment of cancer criteria. Mean age was 66.1 years and standard deviation was 10.7 years (range: 41-84 years). RESULTS: Of the patients, seven (16.6%) were in complete remission, 17 (40.5%) were in partial remission, six (14.3%) had a stable disease, and 12 (28.6%) had a progressive disease. The overall response rate was 57.1 percent. CONCLUSION: 18FDG-PET/CT can be considered as a successful imaging tool in evaluating response to first-line chemotherapy for metastatic bladder cancer. Anatomical and functional data obtained from PET/CT scans may be useful in the planning of secondline and thirdline chemotherapy.

Celiac disease and catatonia: more than a coincidence?

BACKGROUND: Catatonia is a complex neuropsychiatric disorder involving stupor, waxy flexibility, and mutism lasting more than 1 hour. It has arisen mostly from mental and neurologic disorders. Organic causes are more prominent in children. CASE: A 15-year-old female who had refused to eat and drink for 3 days, had not talked, and had stood in a fixed position for long periods was admitted to the inpatient clinic, and she was diagnosed with catatonia. Her maximum score on the Bush-Francis Catatonia Rating Scale (BFCRS) was 15/69 on day 2 of her stay. On neurologic examination, the patient`s cooperation was limited, and she was apathetic to her surroundings and stimuli and inactive. Other neurologic examination findings were normal. To investigate catatonia etiology, her biochemical parameters, thyroid hormone panel, and toxicology screening were conducted but all parameters were normal. Cerebrospinal fluid examination and autoimmune antibodies were negative. Sleep electroencephalography showed diffuse slow background activity, and brain magnetic resonance imaging was normal. As a first-line treatment for catatonia, diazepam was started. With her poor response to diazepam, we continued to evaluate the cause and found the transglutaminase levels were 153 U/mL (normal values, < 10 U/mL). The patient`s duodenal biopsies showed changes consistent with Celiac disease (CD). Catatonic symptoms did not benefit from a gluten-free diet or oral diazepam for 3 weeks. Then, diazepam was replaced with amantadine. With amantadine, the patient recovered within 48 hours, and her BFCRS retreated to 8/69. CONCLUSIONS: Even without gastrointestinal manifestations, CD may present with neuropsychiatric symptoms. According to this case report, CD should be investigated in patients with unexplained catatonia, and that CD may only present with neuropsychiatric symptoms.

Does corneal epithelial thickness show the severity of psoriasis? SD-OCT study.

BACKGROUND: Previous studies have generally focused on dry eye test abnormalities and ocular involvements such as uveitis, and blepharitis in psoriasis. Psoriasis area severity index (PASI), which is used to assess psoriasis severity, is a time-consuming and complex tool. OBJECTIVE: To evaluate the relationship between disease severity and central corneal epithelial thickness (CCET) in psoriasis. METHODS: 175 eyes of 175 psoriasis patients and 57 eyes of 57 healthy individuals as a control group was included in this study. Psoriasis patients were divided into three subgroups according to PASI score as < 10 mild, 10‒20 moderate and > 20 severe. CCET was measured by spectral domain-optical coherence tomography (SD-OCT), and mean values were recorded. Mean CCET values were compared between the psoriasis groups and the control group. Additionally, the relationship between PASI score and CCET was examined. RESULTS: The mean CCET value was 58.06±3.1µm in the mild group, 60.10±5.0µm in the moderate group, 65.75±6.3µm in the severe group and 56.16±3.1µm in the control group. It was determined that the mean CCET value was significantly higher in all psoriasis groups compared to the control group (p<0.001). The mean CCET value was significantly higher in the moderate psoriasis group than in the mild psoriasis group (p=0.018), and in the severe psoriasis group compared to the moderate psoriasis group (p<0.001). There was a strong positive correlation between PASI score and CCET (p<0.001, r=0.519). STUDY LIMITATIONS: Cross-sectional design and a relatively small number of participants. CONCLUSIONS: There is a strong positive correlation between psoriasis severity and CCET. Contactless measurement of CCET by SD-OCT can be an indicator of psoriasis severity.

Acute and chronic stress alter behavioral laterality in dogs.

Dogs are one of the key animal species in investigating the biological mechanisms of behavioral laterality. Cerebral asymmetries are assumed to be influenced by stress, but this subject has not yet been studied in dogs. This study aims to investigate the effect of stress on laterality in dogs by using two different motor laterality tests: the Kong™ Test and a Food-Reaching Test (FRT). Motor laterality of chronically stressed (n = 28) and emotionally/physically healthy dogs (n = 32) were determined in two different environments, i.e., a home environment and a stressful open field test (OFT) environment. Physiological parameters including salivary cortisol, respiratory rate, and heart rate were measured for each dog, under both conditions. Cortisol results showed that acute stress induction by OFT was successful. A shift towards ambilaterality was detected in dogs after acute stress. Results also showed a significantly lower absolute laterality index in the chronically stressed dogs. Moreover, the direction of the first paw used in FRT was a good predictor of the general paw preference of an animal. Overall, these results provide evidence that both acute and chronic stress exposure can change behavioral asymmetries in dogs.
