RESUMEN

The pituitary gland plays an important role in the stress response mechanism. Given the direct link between adjustment disorder and stress, we hypothesized that there might be changes in the pituitary gland in these patients. The study comprised a patient group of 19 individuals with adjustment disorder according to the Diagnostic and Statistical Manual of Mental Disorders Fifth Edition, and 18 healthy controls. The mean pituitary gland volumes of the patient group were not statistically significantly different from those of the healthy control group (80.81 ± 1.82 mm3 in patients with adjustment disorder vs. 81.10 ± 7.04 mm3 in healthy controls, with a statistically nonsignificant difference of P > 0.05). This finding is contrary to our previous findings in anxiety-related disorders. In this regard, adjustment disorder is not similar to anxiety-related disorders in terms of pituitary gland volumes. We should also clearly state that our study is a pioneering study and that studies with large samples are needed to support our findings. The limitations of our study can be attributed to the small sample size, the utilization of a cross-sectional design, and the inclusion of patients using psychotropic drugs.

RESUMEN

BACKGROUND: Although Türkiye (Turkey) hosts the largest number of Syrian refugees, studies on food insecurity are limited. This study examined the prevalence and risk factors of food insecurity among Syrian refugees living in Istanbul, which has the highest number of refugees in Türkiye. METHODS: A cross-sectional survey was conducted among Syrian refugees in Istanbul between September 2021 and March 2022. The main income earners of 103 households were interviewed by a research dietitian, with the assistance of an Arabic speaking interpreter through hour-long face-to-face. Data on sociodemographic characteristics (age, gender, nationality, marital status, educational status, the family income, the major source of family income, and the number of family members living in the household etc.) and household food insecurity status were collected. Household food insecurity status was assessed with the eighteen-item Household Food Security Survey Module. RESULTS: The household food insecurity rate was 90.3%, and those of adults and children were 88.4% and 84.8%, respectively. It was observed that family income level was significantly associated with food insecurity. A one-unit increase in monthly income increased food security by 0.02 times (p < 0.001). The number of employed refugees in the food security group was higher than that in the food insecurity group (p = 0.018). A significant difference was found in the rate of occupation type of the major income earner between the groups (p = 0.046). CONCLUSIONS: High rates of food insecurity, particularly severe food insecurity, were found among Syrian refugees living in Istanbul. While more research is warranted to explore the root causes and efficacy of the current support system, it requires the immediate attention of policymakers at the national and international levels to implement effective policies and interventions.

RESUMEN

AIMS: To determine whether there is a difference in pituitary gland volumes in patients with alcohol use disorder compared to healthy people. METHODS: The subjects included in the study consisted of 15 individuals who met the criteria for alcohol use disorder according to the Diagnostic and Statistical Manual of Mental Disorders Fifth Edition (DSM 5) diagnostic criteria based on the Structured Clinical Interview for DSM 5 and were admitted to Firat University School of Medicine, Department of Psychiatry, or were hospitalized, and 17 healthy controls. The volumes of pituitary were measured in subjects. RESULTS: Absolute pituitary gland volumes of patients with alcohol use disorder and healthy controls were compared in the analysis performed using the independent samples t-test. The mean volume of the patient group was significantly smaller than the healthy controls (58.02 ± 7.24 mm3 in patients with alcohol use disorder vs. 83.08 ± 12.11 mm3, P < 0.01), a difference which persisted after controlling for age, gender and total brain size. CONCLUSIONS: Patients with alcohol use disorder in this study had smaller pituitary gland volumes compared to those of healthy control subjects. However, this study has limitations including small sample size and not adjusting for previous or current medication use or current anxiety and depression.

RESUMEN

The overreaching objective of the current study is to investigate the association of quality of life with Afghan households' food insecurity. The data was collected immediately after the Taliban took control of a large part of Afghanistan. About a total of 555 households' heads participated in a face-to-face interview, using the HFIAS and WHOQOL-100 questionnaires along with some questions related to their socioeconomic characteristics at two different times, before and after the Taliban's takeover. The comparative analysis showed that 98% of Afghan households were food insecure after the Taliban takeover, while 70% of them faced food insecurity before the Taliban's takeover. The quality of life in the Taliban era is worse than before the Taliban. All dimensions of quality of life have decreased, and this decrease was more pronounced for the psychological, environmental, and physical domains. It is recommended that international organizations, NGOs, and local agents focus on these dimensions of the quality of life to improve food security.

RESUMEN

Incidental adrenal masses are seen in 5% of abdominal computed tomography (CT) examinations. Accurate discrimination of the possible differential diagnoses has important therapeutic and prognostic significance. A new handcrafted machine learning method has been developed for the automated and accurate classification of adrenal gland CT images. A new dataset comprising 759 adrenal gland CT image slices from 96 subjects were analyzed. Experts had labeled the collected images into four classes: normal, pheochromocytoma, lipid-poor adenoma, and metastasis. The images were preprocessed, resized, and the image features were extracted using the center symmetric local binary pattern (CS-LBP) method. CT images were next divided into 16 × 16 fixed-size patches, and further feature extraction using CS-LBP was performed on these patches. Next, extracted features were selected using neighborhood component analysis (NCA) to obtain the most meaningful ones for downstream classification. Finally, the selected features were classified using k-nearest neighbor (kNN), support vector machine (SVM), and neural network (NN) classifiers to obtain the optimum performing model. Our proposed method obtained an accuracy of 99.87%, 99.21%, and 98.81% with kNN, SVM, and NN classifiers, respectively. Hence, the kNN classifier yielded the highest classification results with no pathological image misclassified as normal. Our developed fixed patch CS-LBP-based automatic classification of adrenal gland pathologies on CT images is highly accurate and has low time complexity [Formula: see text]. It has the potential to be used for screening of adrenal gland disease classes with CT images.

RESUMEN

PURPOSE: To evaluate the 36 months changes in posterior corneal surface parameters in keratoconic eyes after accelerated corneal cross-linking and to compare the data with uncross-linked progressive and non-progressive keratoconic eyes. METHODS: Thirty five cross-linked, 30 uncross-linked progressive, and 30 uncross-linked non-progressive keratoconic eyes were included. Maximum keratometry (Kmax), thinnest pachymetry, minimum radius of curvature back (Rminback), asphericity back, posterior elevation and corneal densitometry, back corneal higher order aberrations (HOAs), back surface deviation (Db), final D, posterior radius of curvature (PRC) and 'B' unit values were recorded at baseline and at the 12, 24, 36 months follow-up. Data were analyzed with repeated measures ANOVA and paired t-tests. RESULTS: Kmax and thinnest pachymetry were significantly changed in the cross-linked and progressive uncross-linked groups. Rminback, asphericity back, and HOAs did not change in either group. Total posterior corneal densitometry improved; posterior elevation, Db and B unit worsened in the cross-linked group and did not change in the uncross-linked groups. PRC and final D worsened in the cross-linked and progressive uncross-linked groups, and did not change in the non-progressive group. CONCLUSION: Despite a decreased Kmax, the posterior corneal surface parameters, posterior elevation values were determined to have significantly worsened in the cross-linked group and this increase was higher than in progressive uncross-linked eyes.

RESUMEN

PURPOSE: To investigate topographic, tomographic, topometric, densitometric, and aberrometric parameters in subclinical keratoconus with the Pentacam HR imaging system. METHODS: Data of 3128 patients were evaluated, finding in 108 patients clinical keratoconus in one eye and subclinical keratoconus in the other. Corneal topographic, tomographic, topometric, densitometric, and aberrometric values obtained using the Pentacam HR imaging system were compared between clinical keratoconus, subclinical keratoconus, and normal eyes. RESULTS: Comparing eyes with subclinical keratoconus and the control group, while flat K, horizontal coma, horizontal trefoil, and vertical trefoil values were similar (p > 0.05 for each), all other parameters were significantly different (p < 0.05 for each). Densitometry values of eyes with subclinical keratoconus were significantly higher in all layers of the 0-2 mm annular area and in the anterior and central layers of the 2-6 mm annular area compared to the control group (p < 0.05 for each). According to the receiver operating characteristic curve analysis, the densitometry region with the largest area under the curve was the anterior layer of the 0-2 mm annular area. The sensitivity in this region was 79.4% and the specificity 73.2% in distinguishing eyes with subclinical keratoconus from normal eyes when 19.3 GSU was considered the threshold. CONCLUSION: Corneal densitometry values in the 0-2 and 2-6 mm annular areas, especially in the anterior layers, are parameters that can be used to predict and distinguish subclinical keratoconus from normal eyes.

RESUMEN

OBJECTIVES: To evaluate the additive effect of topical nepafenac on pupil diameter (PD) in patients with diabetes mellitus (DM) and cataract. METHODS: This prospective comparative study included the patients having cataract surgery with and without DM. Two consecutive PD measurements were taken using an automatic quantitative pupillometry system (MonPack One, Metrovision). A baseline measurement was taken, then one drop of nepafenac % 0.1 (Nevanac; Alcon, Fort Worth, TX) was instilled only to the eye that will be operated on (study eye). Cyclopentolate 1.0% (Sikloplejin; Abdi Ibrahim, Istanbul, Turkey) was instilled to both eyes (study eye/fellow eye) 5 minutes later. The second measurement was taken at 1 hour after this application. RESULTS: The DM group consisted of 43 patients, and the control group consisted of 39 participants. The baseline PDs of both eyes were similar in the DM group (P=0.070) and the control group (P=0.345). The change in pupil size from baseline to mydriasis was statistically significantly greater in the study eyes (2.69±0.53) than fellow eyes (2.54±0.61) in the DM group (P=0.009), but there was no statistically significant difference in the control group (2.94±0.63 vs. 2.86±0.58). When the groups were compared, the PD changes were similar in the study eyes between groups (P=0.065), while the PD changes in the fellow eyes were lower in the DM group (P=0.017). CONCLUSIONS: Nepafenac has been shown additive effect on pupil dilation in diabetic patients before cataract surgery.

RESUMEN

OBJECTIVES: To evaluate the longitudinal tomographic changes and to compare the discriminatory potential of a novel progression display between progressive and nonprogressive keratoconic eyes. METHODS: Retrospective evaluation was made of 81 eyes of 81 patients with keratoconus who had undergone Scheimpflug measurements at least twice with an interval of 12 months or longer between each measurement. The progressive group was defined as 36 eyes, which showed progression according to the definition of the global consensus on keratoconus and ectatic diseases when 2 of the 3 criteria were met, and the other 45 eyes were considered the nonprogressive group. The main outcome measures from progression display were "A" for anterior radius of curvature, "B" for posterior radius of curvature, "C" for thinnest pachymetry, "D" for distance visual acuity; Kmax; Q-value front and back; index of surface variance (ISV), vertical asymmetry, height asymmetry, and height decentration; overall deviation of normality (final D); average pachymetric progression index; and maximum Ambrósio relational thickness. RESULTS: The rate of change per year of A, B, C, thinnest pachymetry, Kmax, final D, and ISV was significantly different between groups (P≤0.01 for all values). It was determined that yearly change rates greater than 0.12 for A, 0.14 for B, 10.04 µm for thinnest pachymetry, 0.68 D for Kmax, 0.15 for final D, and 2.11 for ISV might indicate progression in keratoconus management. CONCLUSIONS: Belin progression display parameters may be useful in discriminating progressive from nonprogressive keratoconic eyes.

RESUMEN

PURPOSE: To report a case of choroidal neovascularization (CNV) associated with rubella retinopathy (RR) treated with intravitreal aflibercept. CASE PRESENTATION: A 15-year-old girl presented a complaint of visual decrease in her left eye. She had a history of hearing decrease since she was 1 year old in addition to patent ductus arteriosus. On ocular examination, the best corrected visual acuity (BCVA) was 20/20 in the right eye and 20/400 in the left eye. Dilated fundus examinations revealed a classic salt-and-pepper appearance in both eyes and a whitish subretinal lesion with retinal hemorrhages in the left macula. Fundus fluorescein angiography (FFA) of the left eye illustrated a pattern of diffuse spotty fluorescence with an active subfoveal CNV lesion, that hyperfluoresces in the early phases of the FFA, maintains well-demarcated borders, and leaks. Spectral domain optical coherence tomography (SD-OCT) revealed thickened and elevated retinal layers at the macula due to the subretinal and intraretinal fluid with foveal and extrafoveal protruding hyper-reflective lesion in the left eye. Single dose of intravitreal aflibercept was performed to the left eye and at the first month after the injection, the BCVA improved to 20/100 and the OCT revealed scar formation. At the follow-up visits, the macula was similar to those at the first month post-injection, and the BCVA was preserved. No additional injections were needed. CONCLUSION: Intravitreal aflibercept may be a treatment alternative, which provides satisfactory anatomical and functional results and leads to a better visual acuity in cases with RR complicated by CNV.

RESUMEN

PURPOSE: To demonstrate the morphological and physiological characteristics of lens epithelial cells (LECs) in patients with traumatic cataract using transmission electron microscopy (TEM) to further understand penetrating ocular injury-induced cataract morphology and epithelial repair mechanisms involved at a cellular level. METHODS: This is a prospective international study. Sixteen eyes of 16 consecutive patients who were diagnosed as traumatic white cataracts following the anterior lens capsule perforation and 13 eyes of 13 patients with idiopathic posterior subcapsular cataract were included to the study. The anterior lens capsules (aLCs: basement membrane and associated LECs) were obtained from cataract surgery and prepared for TEM. RESULTS: Two prominent cell types were observed in all aLCs of the traumatic cases: degenerated type LECs having variable sized intraepithelial vacuoles close to injury site and normal appearing LECs having an euchromatic nucleus distant from the injury site. In control group, the LECs and all their elements were in normal ultrastructural pattern except some small intraepithelial vacuoles, which were fewer and smaller than the vacuoles in the degenerated LECs of the traumatic group. CONCLUSIONS: The ultrastructural findings of our cases support that traumatically induced dysfunction of the lens epithelium may lead to an edema in superficial cortical lens fibers that subsequently undergo degeneration and produce a localized zone of vacuolization.

RESUMEN

PURPOSE: To evaluate the corneal and tear film characteristics in patients with gout and compare these data with those of healthy subjects and to investigate the correlation of corneal densitometry with uric acid value and duration of disease. METHODS: Forty-one eyes of 41 patients with gout (group 1) and 40 eyes of 40 healthy subjects (group 2) were included in this study. Detailed ophthalmologic examinations were performed on all participants. Corneal tomographic analyses were performed with the Pentacam HR Scheimpflug imaging system (Oculus, Wetzlar, Germany). Maximum keratometry (Kmax), central corneal thickness (CCT), corneal volume (CV), and corneal densitometric values were compared between groups. Tear function tests including Schirmer, tear breakup time, and fluorescein staining were performed and compared between groups. RESULTS: Groups were similar in terms of age and gender. Kmax, CCT, and CV values were similar between groups. The outcomes of tear function tests were similar between groups. Corneal densitometric values for the 0-2 and 2-6 mm zones of the anterior and center layers were significantly higher in group 1 compared to group 2. This densitometric increase was positively correlated with uric acid levels and gout duration. CONCLUSIONS: Corneal densitometry values of the 0-2 and 2-6 mm zones of the anterior and central layers were higher in patients with gout than those of the control subjects, and the densitometric values increased as uric acid level and disease duration increased.

RESUMEN

The present study comparatively assesses how Afghan refugees in Pakistan understand both the factors and barriers affecting their food security status before and after refuge. Through qualitative in-depth interviews with 25 Afghan refugee families, we assess how quality of life, together with perceptions of a balanced meal, food environments both pre- and post-migration and push and pull factors of migration, impact food security and food choices for refugee families. Furthermore, our results reveal that regardless of the length of protracted status for Afghan refugees, food insecurity remains as a consistent condition for refugee families.

RESUMEN

PURPOSE: To assess the decentration and angle of tilt of the intraocular lens (IOL) according to the intravitreal tamponade types used in combined phacoemulsification and vitreoretinal surgery. METHODS: This prospective and randomized clinical study involved 73 eyes of 69 patients who underwent combined vitreoretinal surgery. Eyes with intravitreal tamponades formed the study group and eyes without intravitreal tamponades formed the control group. The study group was further divided into silicone oil and gas tamponade subgroups. Cross-sectional IOL images were captured using a Pentacam HR (Oculus, Germany) and tilt and decentration were calculated with Adobe Photoshop software (Adobe, San Jose, CA). RESULTS: The mean angle of tilt and decentration at the vertical meridian were significantly higher in both tamponade groups than in the control group (P < 0.05 for all). No significant difference was observed among the groups regarding IOL position parameters at the horizontal meridian (P > 0.05). When comparing the silicone oil and gas tamponade subgroups, no significant differences were noted on the position of IOL at both meridians (P > 0.05 for all). CONCLUSION: Intravitreal tamponades have an important effect on the position of IOL in combined vitreoretinal surgery. Silicone oil and gas tamponades may induce postoperative tilt and decentration of one-piece acrylic IOLs.

RESUMEN

OBJECTIVES: To investigate the shifting of the line of sight (LoS) and the refractive, topographic, and aberrometric parameters that may be associated with the shifting of the LoS in eyes with tilted disk syndrome (TDS). METHODS: Eighty left eyes of 80 subjects with TDS (Study Group) and 70 left eyes of 70 subjects with myopia and astigmatism (Control Group) were included in this study. Line-of-sight coordinates on the horizontal (x) and vertical (y) axes, refractive, topographic, and aberrometric parameters were evaluated. All parameters were compared between groups, and correlations were analyzed for the study group. RESULTS: In the study group, the LoS significantly shifted to the superotemporal direction compared with the control group (P=0.022 and P=0.008 respectively). The shift on y-axis was correlated with mean cylindrical refractive error (r=-0.283, P=0.011), total root mean square (RMS) (r=0.321, P=0.004), higher-order aberration RMS (r=0.300, P=0.007), vertical coma (r=0.430, P<0.001), and vertical trefoil values (r=-0.455, P<0.001). CONCLUSIONS: Results demonstrated a superotemporal shifting of the LoS in eyes with TDS. As eyes with TDS have an important place among candidates for refractive and multifocal intraocular lens implantation surgeries, this shift must be accounted for to prevent decentralization and provide satisfactory outcomes.

RESUMEN

PURPOSE: To investigate the effect of Helicobacter pylori (H. pylori) infection on choroidal thickness (CT) and retinal nerve fiber layer thickness (RNFLT). METHODS: The study included 25 patients with H. pylori infection and 25 healthy individuals as the control group. Helicobacter pylori patients were classified as the pre-treatment (Group 1; n: 25) and the post-treatment (Group 2; n: 25). RNFLT and CT were measured before and after treatment of H. pylori infection, using enhanced depth imaging (EDI) spectral-domain optical coherence tomography (Spectralis, Heidelberg Engineering, Heidelberg, Germany). The axial length and intraocular pressure were also measured. RESULTS: The mean subfoveal CT was 320.96 ± 29.15 µm in Group 1 and 287.48 ± 49.17 in the control group (p = 0.007), while the mean subfoveal CT did not show any difference between Group 2 and the control group (p > 0.05). No statistically significant difference was determined between the H. pylori patients and the control group in respect of RNFLT values (p > 0.05). CONCLUSIONS: CT increases during H. pylori infection and returns to the normal range within 6 weeks of treatment. RNFLT does not show any change during H. pylori infection. The data related to the subfoveal CT may be useful in understanding the pathogenesis of central serous chorioretinopathy developing in H. pylori patients.

RESUMEN

In this prospective study, the biomechanical properties of optic nerve head (ONH) and cornea in both eyes of patients with non-arteritic anterior ischaemic optic neuropathy and healthy control eyes were investigated. ONH elastometry was measured with real-time elastography, and corneal elastometry was measured with ocular response analyser. Elastometry of cornea and ONH was lower in both eyes of patients with unilateral non-arteritic ischaemic optic neuropathy than in healthy control eyes. The role of these biomechanical differences in the pathogenesis of non-arteritic ischaemic optic neuropathy should be investigated further.

RESUMEN

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.

RESUMEN

BACKGROUND We present a clinical experience with a new local flap procedure, namely the triangular closure technique, for reconstruction of sacrococcygeal skin defects resulting from excision of the pilonidal sinus. MATERIAL AND METHODS In this technique, the defect is surgically converted to a triangle in shape. Then, the triangular defect is closed by transposition of 2 skin flaps designed in an unequal z-plasty manner. Over 6 years, this technique has been used for closure of defects of chronic pilonidal sinus disease in 27 patients (6 females, 21 males). The size of the defect ranged between 3.5 cm and 12 cm in dimension. RESULTS A tension-free defect closure was obtained in all patients. All flaps except one healed with no complications. A mean follow-up of 3.62±1.77 months revealed aesthetically and functionally acceptable results with the obliteration of the natal cleft in all patients. No recurrence was observed in the follow-up period. CONCLUSIONS The triangular closure technique was found to be a useful technique for the treatment of pilonidal sinus with favorable results regarding the time before return to work.

RESUMEN

Basal cell carcinoma (BCC) is the most common tumor in humans. Reduced expression of sirtuins interferes with DNA repair, which may cause mutations and genomic instability, and eventually leads to tumor development. In the present study, we investigate the expression levels of SIRT genes in non-tumoral and tumor tissues of patients with BCC. A total of 27 patients (16 males, 11 females) with BCC were included in the study; the mean age was 65.40 ± 10.74 years and mean follow-up was 2.5 ± 0.5 years. There were multiple synchronous lesions in six patients, and the remaining 21 patients had a single lesion. Tumor and non-tumoral tissue samples were collected from all patients, and mRNA expression levels of SIRT1-7 (Sirt1.1, Sirt1.2, Sirt2, Sirt3, Sirt4, Sirt5, Sirt6, and Sirt7) were examined by real-time PCR. The results showed that expressions of SIRT1.1, SIRT1.2, SIRT4, SIRT5, SIRT6, and SIRT7 mRNAs were unchanged in tumor tissues of BCC patients compared with non-tumoral tissue samples. Importantly, the expressions of SIRT2 and SIRT3 mRNAs were significantly reduced in tumor tissue samples from BCC patients compared with non-tumoral tissues (P = 0.02 and P = 0.03, respectively). In light of the previous reports that have demonstrated a link between SIRT proteins and cancer, our findings suggest that SIRT2 and SIRT3 may plan important roles in BCC pathogenesis and could be candidate prognostic biomarkers for BCC.
