    Background/Aim Visual acuity and stereopsis both play an important role in developing posture and balance in children. The aim of this study was to investigate whether children with traumatic dental injuries (TDI) have abnormal stereopsis, due to a reduction in visual acuity, compared to children with good dental health. Material and Methods A total of 140 participants (75 with traumatic dental injuries resulting from falls and crashes, and 65 age-matched controls without dental trauma) were enrolled in this prospective, cross-sectional study. The participants underwent complete dental and ophthalmologic examinations. After the ophthalmologic examination, the stereo acuities were assessed by a Titmus stereo test at 40 cm. Results Titmus test scores were significantly worse in the TDI group (mean score 252.46 +/- 629.12 seconds of arc) compared to the control group (mean score 56 +/- 27.39 seconds of arc) (P < .05). The percentage of subjects with abnormal Titmus test scores was higher in the TDI group (28%) than in the control group (3.1%). The mean anisometropia value was 3.03 +/- 2.37 D and 0.55 +/- 0.41 D in the TDI group and the control group, respectively (P < .001). The severity of anisometropia correlated with the degree of stereopsis (r = .83,P < .01). Conclusions The presence of abnormal stereopsis may lead to postural instability which can lead to traumatic dental injuries. The prevalence of abnormal stereopsis in children with TDI was higher than in children with good binocular vision and stereopsis

    Aim. The current study was aiming to investigate the relation between vitamin D, retinopathy, and hearing loss among type 2 diabetes mellitus (T2DM) patients. Methods. Cross-sectional study carried on 638 subjects aged between 20 and 60 years who visited the Endocrinology, Ophthalmology, and ENT Outpatient Clinics of the Medipol Hospital during the period from March 2016 to May 2017. Two audiometers Grason Stadler GSI 61 and Interacoustics AC40 Clinical audiometer were used to evaluate the hearing loss. Risk factors for diabetic retinopathy were evaluated, including age, sex, diabetes duration, glycated hemoglobin (HbA1c), hypertension, and lipid profiles. Results. The mean age (+/- SD, in years) for retinopathy with hearing loss versus normal subjects was 47.7 +/- 10.2 versus 48.5 +/- 9.1. The associated risk factors were significantly higher in T2DM with hearing loss, hypertension (32.6% versus 15.7%), tinnitus (40.0% versus 18.0%), vertigo (59.7% versus 26.8%), and headache (54.9% versus 45.3%), than in normal hearing diabetes. There were statistically significant differences between hearing impairment versus normal hearing for vitamin D [19.40 +/- 9.71 ng/ml versus 22.67 +/- 9.28ng/ml; p<0.001], calcium, magnesium, phosphorous, cholesterol, HDL-C, LDL-C, albumin, systolic blood pressure [131.70 +/- 9.25 Hg versus 127.73 +/- 1.98 Hg], diastolic blood pressure [82.20 +/- 8.60 mm Hg versus 79.80 +/- 8.20 mm Hg], and microalbuminuria. Multivariate logistic regression analysis revealed that variables such as vertigo, duration of DM, mobile/I pad phone, vitamin D deficiency, sleeping disturbance, headache, frequently TV watching, tinnitus, cigarette smokers, and hypertension were considered at higher risk as a predictors of retinopathy with hearing loss among diabetic patients. Conclusion. Vitamin D deficiency is considered as a risk factor for diabetic retinopathy and hearing loss among diabetic patients. Meanwhile, hyperglycemia could be considered as a modifiable risk factor for diabetic retinopathy; Light glycemic control may be the most effective and important therapy for improving quality of life and substantially reducing the incidence of retinopathy and in T2DM patients

    The tumor lysis syndrome (TLS) is a collection of metabolic abnormalities that occur in consequence of the release of intracellular contents following lysis of tumor cells. TLS occurs spontaneously or after chemotherapy. Spontaneous TLS is uncommon occurrence in multiple myeloma (MM). We define a case of a 70-year-old woman patient who was found to have MM with spontaneous TLS, following a compression fracture of the T-12 vertebrae. While serum uric acid and phosphorous levels were high, low calcium levels were identified. There were also acute kidney injury and metabolic acidosis. Upon the diagnosis of TLS, she was treated with hydration, allopurinol, sodium bicarbonate, and calcium gluconate. The improvement of her laboratory data was observed. We submitted this case in order to draw attention to the presentation of MM with spontaneous TLS

    Abstract: Purpose: To show how a private eye care center in Turkey initiated Six Sigma principles to reduce the number of complications encountered during and after femtosecond laser-assisted LASIK (IntraLase) surgeries. Method: Data were collected for five years. To analyse the complications among 448 surgeries, main tools of Six Sigma’s Define-Measure-Analyze-Improve-Control (DMAIC) improvement cycle such as SIPOC table, Fishbone Diagram and, Failure, Mode and Effect Analysis were implemented. Sources and root causes of seventeen types of complications were identified and reported. Results: For a successful IntraLase surgery, experience of the refractive surgeon, patient’s anatomy and calibration of laser power were determined to be the “critical few” factors whereas, patient’s psychology, sterilization and hygiene, and suction-ring’s pressure were found to be the “trivial many” factors. The most frequently occurring complication was found to be subconjunctival haemorrhage. Conclusion: The process sigma level of the process was measured to be 3.3547. The surgical team concluded that sixteen complications (out of seventeen) should be significantly reduced by taking the necessary preventive measures

    ABSTRACT Purpose: The aim of this study was to evaluate tear osmolarity, tear film function, and ocular surface changes in patients with psoriasis. Methods: At a single center, 30 eyes of 30 patients with psoriasis (group 1) and 30 eyes of 30 healthy individuals (group 2) were evaluated using the Ocular Surface Disease Index (OSDI) questionnaire, Schirmer I test, tear film break-up time (TBUT) test, scoring of ocular surface fluorescein staining using a modified Oxford scale, and tear osmolarity measurement. Results: Tear osmolarity values, OSDI, and Oxford scale scores were significantly higher in group 1 (309.8 ± 9.4 mOsm, 38.9 ± 1.1, and 0.7 ± 1.1, respectively) than in group 2 (292.7 ± 7.7 mOsm, 4.2 ± 0.3, and 0.1 ± 0.3, respectively; p<0.01 for all). TBUT was significantly lower in group 1 (8.7 ± 3.6 s) than in group 2 (18.1 ± 2.8 s; p<0.001). No significant differences were detected in Schirmer I test values between the groups (16.2 ± 2.5 mm in group 1 and 16.6 ± 2.3 mm in group 2; p=0.629). Conclusions: The results of this study showed that psoriasis may influence tear osmolarity and tear film function. Patients with psoriasis showed tear hyperosmolarity and tear film dysfunction

    The purpose of this study is to show how a private eye care center in Turkey initiated Six Sigma principles to reduce the number of complications encountered during and after intravitreal injections. Data were collected for 30-months. To analyse the complications among 229 injections administered on 106 patients, main tools of Six Sigma’s Define-Measure-Analyze-Improve-Control (DMAIC) improvement cycle such as SIPOC table, Fishbone Diagram and, Failure, Mode and Effect Analysis were implemented. Sources and root causes of seven types of complications were identified and reported. For a successful intravitreal injection, experience of the retina specialist, attention of the retina specialist and patient’s ocular pathology were determined to be the “critical few” factors whereas, sterilization and hygiene, dosage of drug/agent and chemical properties of drug/agent were found to be the “trivial many”factors. The most frequently occuring and the complication with the highest hazard score was found to be subconjunctival haemorrhage. The process sigma level of the process was measured to be 3.2657. The surgical team concluded that six of the complications (out of seven) should be significantly reduced by taking the necessary preventative measures

    Objective We aimed to investigate the prevalence and etiology of potassium abnormalities (hypokalemia and hyperkalemia) and management approaches for hospitalized patients. Subjects and Methods Over a 4-month period, all hospitalized patients at Hacettepe University Medical Faculty Hospitals who underwent at least one measurement of serum potassium during hospitalization were included. Data on serum levels of electrolytes, demographic characteristics, cause(s) of hospitalization, medications, etiology of potassium abnormality and treatment approaches were obtained from the hospital records. Results Of the 9,045 hospitalized patients, 1,265 (14.0s%) had a serum potassium abnormality; 604 (6.7s%) patients had hypokalemia and 661 (7.30s%) had hyperkalemia. In the hypokalemic patients, the most important reasons were gastrointestinal losses in 555 (91.8s%) patients and renal losses in 252 (41.7s%) patients. The most frequent treatment strategies were correcting the underlying cause and replacing the potassium deficit. Of the 604 hypokalemic patients, 319 (52.8s%) were normokalemic at hospital discharge. The most common reason for hyperkalemia was treatment with renin-angiotensin-aldosterone system blockers in 228 (34.4s%) patients, followed by renal failure in 191 (28.8s%). Two hundred and ninety-eight (45.0s%) patients were followed without any specific treatment. Of the 661 hyperkalemic patients, 324 (49.0s%) were normokalemic at hospital discharge. Conclusion This study showed a high prevalence of potassium imbalance among hospitalized patients. Although most of the potassium abnormalities were mild/moderate, approximately half of the patients treated for hypokalemia or hyperkalemia were discharged from the hospital with ongoing dyskalemia.PubMedWoSScopu

    Compared to pediatric age group, the prognosis of adult acute lymphoblastic leukemia (ALL) is still dismal even in patients receiving allogeneic hematopoietic cell transplantation (AHCT). We retrospectively analyzed 205 adults (male: 122; female: 83) with ALL who underwent AHCT. Median age of patients was 28 (18-59). Fifty-two patients had Ph+ ALL. The estimated relapse free and overall survival (OS) of the study cohort at 1, 2 and 3 years were 52.3%/63.9%, 42.9%/49.5% and 39.9%/45.6%, respectively. On multivariate analysis, first complete remission at the time of AHCT, TBI-based conditioning and development of chronic graft-versus-host disease were only factors, which were significantly associated with prolonged OS.
