Abstract
OBJECTIVES To detect the serum level of thyroid hormones, vitamin D and vitamin D receptors (VDR) polymorphism in keratoconus (KC) patients and to identify the association between vitamin D deficiency and thyroid dysfunction in KC. METHODS This cross sectional study included 177 KC patients with no thyroid disorders compared to 85 healthy controls with normal corneal tomography. Measurements of thyroid stimulating hormone (TSH), free triiodothyronine (FT3), free tetraiodothyronine (FT4) and serum 25-OH vitamin D were done using Enzyme linked immusoassay (ELISA test). VDR polymorphisms were tested including [Taq I (rs731236), Apa I (rs7975232) and Bsm I (rs1544410)] using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). RESULTS An increase in frequency of thyroid disorders (P = 0.04), decrease in serum 25(OH) vitamin D level (P < 0.001), Taq 1 and tt genotype (P < 0.001) were significantly distributed in KC patients. A significantly higher serum 25(OH) vitamin D level was reported in TT genotype, while insufficient level was more common in Tt genotype (P < 0.001). A deficient serum 25(OH) vitamin D level was predominant in tt genotype (P < 0.001). A 95% confidence interval was in TSH (1.603, 2.946), FT4 (24.145, 77.06), hypothyroidism (1.062, 67.63), insufficient (2.936, 11.643) and deficient vitamin D (5.283, 28.704) and all were significant risk factors for KC with (P < 0.05). CONCLUSIONS Both thyroid disorders and low vitamin D are potential factors for KC development. Studying VDR at the molecular level provides interesting avenues for future research toward the identification of new KC cases.

Abstract
(1) Background: Type 2 diabetes mellitus (T2DM) and metabolic syndrome are associated with decreased vitamin D. In contrast, high pro-neurotensin (pro-NT) levels are linked with an increased risk of T2DM and cardiovascular disease. We aimed to determine the validity of pro-NT and 25-dihydroxy vitamin D3 levels as predictors for T2DM complications; (2) Methods: One hundred T2DM, and one hundred healthy volunteers participated in this case-control study. Their Pro-NT and 25-hydroxyvitamin D3 levels were evaluated using the ELISA technique; (3) Results: Pro-NT and 25 (OH) vitamin D3 have significant validity and accuracy in T2DM prediction, 84.5%, and 90.5%, respectively (p = 0.001). At a value of <29.5, 25-Hydroxy vitamin D3 showed 88% sensitivity and 93% specificity in predicting T2DM. At a value of >124 Pmol/L, Pro-NT showed 81% sensitivity and 88% specificity in predicting T2DM. At a value of 16.5, 25-Hydroxy vitamin D3 had 78.4% sensitivity and 68.3% specificity in predicting T2DM complications. At a value of >158 pmol/L, Pro-NT predicted T2DM complications with 67.6% sensitivity and 56.0% specificity; (4) Conclusions: 25 (OH) Vit D3 and Pro-NT could identify T2DM patients and predict T2DM complications. More extensive research is required to adequately validate this novel perspective with a large population study.

Abstract
Background COVID-19 (SARS-CoV-2/2019-nCoV) is now a major public health threat to the world. Olfactory dysfunctions (ODs) are considered potential indicating symptoms and early case identification triaging for coronavirus disease 2019 (COVID-19). The most common reported comorbidities are diabetes mellitus, chronic lung disease, and cardiovascular disease. The objective of this study was to evaluate prevalence of different types of smell disorders in patients with laboratory-confirmed COVID-19 infection and impact of involved systemic diseases. Methodology A cross-sectional retrospective study has been done for patients with laboratory-confirmed COVID-19 infection (mild-to-moderate). The data collected from patient's files and developed online electronic questionnaire (WhatsApp) based on the patients most common and recurrent reported data including: a) symptoms of olfactory dysfunction and associated covid19 symptoms fever and headache, cough, sore throat, pneumonia, nausea, vomiting and diarrhea, arthralgia and myalgia and taste dysfunction. b) Associated systemic diseases including: diabetes, hypertension, asthma, chronic renal disease, chorionic liver disease and hypothyroidism. Results Of 308 patients confirmed with Covid-19 infection, (72.4%) developed OD distributed as follows; complete anosmia (57.8%), troposmia (8.4%), hyposmia (2.9%), partial anosmia (2.6%) and euosmia (0.6%). Significantly increased prevalence of diabetes, hypertension asthma in the group with olfactory dysfunction (p < 0.001), chronic liver disease (p = 0.005), and hypothyroidism (p = 0.03). Conclusion The development of ODs after Covid-19 infection was associated with mild disease form and lower hospitalization. In addition, it showed significant relationship with preexisting systemic diseases. Anosmia is the common modality of ODs.

Abstract
PURPOSE The aim of this study was to assess corneal densitometry and visual outcomes after big-bubble deep anterior lamellar keratoplasty (BB-DALK) and manual dissection deep anterior lamellar keratoplasty in patients with keratoconus. METHODS This retrospective comparative observational study included 40 keratoconic patients who underwent DALK surgery: 22 eyes had BB-DALK (group I) and 18 eyes had failed BB technique and DALK was completed by manual dissection (group II). Best -corrected visual acuity (BCVA), corneal topographic parameters, residual stromal tissue thickness, and endothelial cell count were recorded at 1, 3, 6, and 12 months postoperatively. Densitometric analysis of different corneal layers and zones was performed using Scheimpflug tomography at each visit; values were recorded and compared between the 2 groups. RESULTS At 1 and 6 months postoperatively, BCVA was better in group I than in group II, but with no statistically significant difference. At 12 months, the visual acuities became nearly similar in both groups (0.30 ± 0.13 vs. 0.30 ± 0.14 logarithm of the minimum angle of resolution, P = 0.888). Regarding corneal densitometric analysis, the recorded values for the posterior corneal layer were significantly higher in group II compared with group I at 3, 6, 9, and 12 months postoperatively in the 0- to 2-mm zone (P < 0.001) and the 2- to 6-mm zone (P = 0.029, 0.028, 0.001, and <0.001). CONCLUSIONS Manual dissection DALK after failed BB technique may affect the interface stromal reflectivity up to 12 months postoperatively. However, this does not significantly affect the visual acuity in comparison with successful BB-DALK.

Abstract
PURPOSE To analyze the corneal tomographic parameters of patients with thyroid gland dysfunction. METHODS This case-control study included 100 eyes of 50 patients with thyroid gland dysfunction and 100 eyes of 50 healthy controls. All eyes were examined by Pentacam (Oculus Optikgeräte GmbH). Pentacam parameters were compared between patients with thyroid gland dysfunction and controls. Spearman's correlation coefficient between different Pentacam parameters and the serum level of free thyroxin (T4) and thyroid-stimulating hormone (TSH) was calculated. RESULTS Patients with hypothyroidism had significantly higher median values of steep and maximum simulated keratometric readings, central corneal thickness (CCT), and thinnest pachymetry (CTmin) than both patients with hyperthyroidism and controls (P⩽ .05). The median values of the average and maximum pachymetric progression index (PPI), posterior elevation, and back difference elevation were significantly higher in patients with hyperthyroidism than in patients with hypothyroidism and controls (P ⩽ .05). The Ambrósio Relational Thickness (ARTmax) was significantly reduced in patients with hyperthyroidism (P ⩽ .001). Both CCT and CTmin showed a moderately positive correlation with serum TSH level and a moderately negative correlation with serum free T4 level. Patients with non-autoimmune thyroid gland dysfunction had significantly thinner CCT, CTmin, and inferior vertical deviation than the autoimmune group (P ⩽ .05). CONCLUSIONS Thyroid gland dysfunction is associated with significant corneal tomographic changes. Patients with hyperthyroidism tend to have thinner corneas and more abnormal tomographic parameters correlating with keratoconus. No significant tomographic changes were found in association with autoimmune thyroid gland dysfunction. The authors recommend screening and regular follow-up of patients with thyroid gland dysfunction for early detection and management of keratoconus. [J Refract Surg. 2021;37(3):192-197.].

Abstract
Background Various surgical techniques have been described, to be combined with cataract surgery in glaucoma patients, aiming for an additional reduction of intraocular pressure (IOP), hence minimizing the burden of anti-glaucoma medication (AGM). Ultrasound ciliary plasty (UCP) is a recent microinvasive glaucoma surgery (MIGS) recommended for primary and refractory glaucoma. This study was conducted to evaluate the safety and efficacy of a new technique; combined phacoemulsification and ultrasound ciliary plasty (Phaco-UCP) as a primary surgical treatment for coexisting cataract and open angle glaucoma. Methods A randomized clinical trial, including 61 eyes of 61 patients with visually significant cataract and open angle glaucoma, randomized to either Phaco-UCP (study group; 31 eyes) or phacoemulsification alone (Phaco-alone) (control group; 30 eyes). Primary outcomes included reduction in IOP and/or the number of AGM. Secondary outcomes included visual acuity improvement and complications. Qualified Success was defined as an IOP reduction ≥ 20% from baseline value, with an IOP 6–21 mmHg, with no additional AGM or glaucoma surgery. Failure was defined as either < 20% IOP reduction, despite AGM use, the need of glaucoma surgeries or serious complications. Results At 18 months postoperatively, Phaco-UCP group had a median IOP reduction of 7 mmHg (Q1, Q3 = 3, 10) compared to 2 mmHg (Q1, Q3 = 2, 3) in Phaco-alone group (P < 0.001). Phaco-UCP group had significantly higher success rate at all time points reaching 67.7% at the last follow-up versus 16.7% only in Phaco-alone group (P< 0.001). The median number of AGM significantly decreased from [3 (Q1, Q3 = 2, 4), 3 (Q1, Q3 = 2,3)] respectively, (P =0.3)] at baseline to [1 (Q1,Q3 = 1, 2), 2 (Q1,Q3 = 2, 2)] respectively, (P < 0.001)] at 18 months postoperatively. No serious intraoperative or postoperative complications were encountered in either group. Conclusion Phaco-UCP is a simple, safe and effective procedure for management of coexisting cataract and open angle glaucoma. Trial registration ClinicalTrials.gov identifier, NCT04430647; retrospectively registered. June 12, 2020.

Abstract
AIM To assess the effect of photoactivated chromophore for keratitis crosslinking (PACK-CXL) in case of severe keratitis with melting on the electrophysiological function of the retina and the optic nerve. METHODS The study included 32 eyes of 32 patients with smear positive severe infectious keratitis with corneal melting. The patients were randomly divided into two groups. Group I (control group) included 16 eyes received systemic and topical antimicrobial drugs guarded by culture and sensitivity test. Group II underwent CXL and then continued their antimicrobial treatment. Full field electroretinogram (ERG) and flash visual evoked potential (VEP) were done for each patient in both groups basically and then 1wk, 1 and 3mo post-treatment to assess the changes in the electrophysiological function of the retina and optic nerve. RESULTS Healing of 10 eyes in group I in comparison to 14 eyes in group II was recorded. The mean duration of healing was 36.56±5.21d in group I vs 20.2±4.4d in group II (P<0.005). In group II, ERG showed an insignificant reduction of all parameters of ERG and VEP after CXL. The amplitude of scotopic rod response, oscillatory potential amplitude, flicker amplitude and photopic cone response were insignificantly decreased (P=0.4, 0.8, 0.1, and 0.3 respectively). There were insignificant prolongation of latencies of scotopic rod, oscillatory potential, flicker and photopic cone response (P=0.2, 0.7, 0.5 and 0.1). There was slight delay in latency of VEP without a significant reduction in amplitude. CONCLUSION CXL is an effective technique in treatment of severe infectious keratitis with melting as it halts the melting process with acceptable safety on the retinal and optic nerve function.

Abstract
1. This study was undertaken to examine the effect of feeding glycine (Gly)-fortified low protein (LP) diets on the growth performance, duodenal morphology and caecal microbial populations of broiler chickens raised under unheated, cyclic or constant heat stress environmental conditions. 2. From d 1 to 21 (starter phase), an equivalent number of birds were fed either a normal protein (NP) diet or a LP diet fortified with Gly. From d 22 to 42 (grower phase), an equivalent number of birds from each starter diet were distributed to one of the following dietary groups: (i) an NP diet during the starter and grower phases (NPNP), (ii) an NP diet during the starter phase and a LP diet during the grower phase (NPLP), (iii) an LP diet during the starter phase and an NP diet during the grower phase (LPNP) or (iv) LP diets during both phases (LPLP). 3. Commencing from d 22, an equivalent number of birds from each dietary group were exposed to (i) 23 ± 1°C throughout (unheated), (ii) 34 ± 1°C for 7 h each day from 10:00 to 17:00 (cyclic heat) or (iii) 34 ± 1°C throughout (constant heat). 4. Feeding the LP diet during the starter phase resulted in feed intake (FI), weight gain (WG), feed conversion ratios (FCR) and energy efficiency ratios (EER) similar to those for the NP diet. The birds fed the LP diet had a significantly higher protein efficiency ratio (PER) compared with the birds fed the NP diet. 5. During the grower phase, there were significant diet × temperature interactions for F, WG, FCR, PER, EER, villus height, crypt depth and caecal Clostridia. The birds fed the NPLP and LPLP diets had lower FI, WG and EER, higher FCR, shorter villus height and crypt depth and higher caecal Clostridia compared with the birds fed LPNP and NPNP diets under constant heat stress. However, feeding birds the NPLP and LPLP diets resulted in FI, WG, EER, FCR, morphology parameters and caecal Clostridia equivalent to the birds fed LPNP and NPNP diets, as well as improved PER, under unheated and cyclic heat stress conditions. 6. In conclusion, our results indicate that Gly-fortified LP diets can be fed to broilers under normal and acute heat stress environmental conditions without any adverse effects on performance. However, the use of such LP diets can be detrimental to broilers under chronic heat stress conditions.

Abstract
Background Keratoconus (KC) is usually a bilateral corneal ectatic disease. For significant asymmetric presentation (so called unilateral KC), the fellow eye has the mildest and earliest form of the disease, which is typically called forme fruste keratoconus. The aim of this study was to evaluate the sensitivity and specificity of parameters derived from a Scheimpflug imaging system (Pentacam) as well as the changes in the quality of mesopic vision in the apparently normal fellow eye (forme fruste) to detect the earliest and most sensitive parameters. Methods Patients with clinical keratoconus in one eye and forme fruste keratoconus in the fellow eye were compared to subjects with normal eyes. The patients were examined using a rotating Scheimpflug imaging system (Pentacam).The following parameters were evaluated: keratometry, minimum corneal thickness, pachymetry progression index (PPI), Ambrósio relational thickness (ART), posterior elevation, back difference elevation (BDE) and multimetric D index(D index). Receiver operating characteristic (ROC) curves were analyzed by evaluating the area under the curve (AUC) to detect the sensitivity and specificity of each parameter. Mesopic vision evaluations were performed by contrast sensitivity and glare tests for each group. Results A total of 48 patients with clinical keratoconus in one eye and forme fruste keratoconus in the fellow eye and 72normal subjects were evaluated. In the clinical keratoconus eyes, the mean K, back difference elevation (BDE), pachymetric progression index maximum(PPI max), and multimetric D were significantly higher compared to the normal subjects, whereas the corneal pachymetry and Ambrósio relational thickness maximum (ART max) were significantly lower. In the forme fruste eyes, the ROC analysis showed that the AUC values of the mean K, thinnest pachymetry, ARTmax, BDE, D index, and PPI max were 0.82, 0.61, 0.88, 0. 67, and 0.64, respectively. The contrast sensitivity and glare tests were significantly affected in the forme fruste cases. Conclusion In forme fruste keratoconus eyes, the ART max is considered a highly sensitive objective parameter. Contrast sensitivity and glare is an important subjective test, which is affected in forme fruste patients.

Abstract
We determined the sacral reflex latency in 108 neurologically normal subjects and 110 patients with neurological lesions by applying stimulating current to the glans penis or clitoris and measuring the response with electrodes inserted in the external urethral and anal sphincters. In normal men the mean latencies were 34.6 plus or minus 5.1 (standard deviation) msec. at the external urethral sphincter and 36.0 plus or minus 5.2 msec. at the external anal sphincter. In normal women the mean latencies were 37.4 plus or minus 5.5 msec. at the external urethral sphincter and 38.6 plus or minus 4.0 msec. at the external anal sphincter. The mean reflex latency in patients with upper motor neuron lesions was significantly shorter. To our knowledge this is the first single electrophysiological test to show a difference between such patients and normal subjects. An increased mean latency was found in patients with lower motor neuron impairment. We conclude that measurement of sacral reflex latency can add to the diagnostic information obtained from conventional electromyography and cystometry.

Abstract
Total activity of creatine kinase (CK), lactate dehydrogenase (LD), aldolase (Ald), glutamico-oxaloacetic transaminase (GOT), and LD-isoenzyme distribution was studied in serum and muscle biopsies from normal persons and 117 patients with different types of muscular dystrophy: 82 Duchenne type (DMD), 12 BEcker type, 7 facioscapulohumeral (FSHMD), and 16 limb girdle (LGMD). Total enzyme activity in sera and muscle homogenates was determined by spectrophotometric assays. LD isoenzymes were separated by electrophoresis on agarose gel plates in barbital buffer (pH 8.6), scanned and quantitated. The amounts of the 2 types (M and H) of LD isoenzymes were calculated and the ratio of M/H in serum and muscle was used as an index to differentiate among the types of muscular dystrophy. Serum enzyme activity was elevated to variable degrees reflecting a corresponding decrease in muscle enzymes in the different muscular dystrophies. Patterns of LD isoenzymes in serum and muscle were specific to each type of muscle disease. Increase in serum LD5 (the muscle LD fraction) was a common feature in muscle damage. Changes in the amounts of M and H types in the subunits of LD correlated to the existence and severity of muscle damage. The mean muscle M/H ratio was 6.4 in controls, 1.8 in early DMD, 0.1 in late DMD, 3.0 in Becker type, 3.8 in FSHMD and 3.9 in LGMD. The muscle LD isoenzyme distribution in DMD showed a shift toward a more aerobic fetal muscle pattern. This is a result of the gradual disappearance of the mature anaerobic LD-type (M) and the increase in synthesis of the aerobic fetal LD-type (H) during the progression of the disease. This report provides a comparative study of the LD isoenzyme patterns in muscular dystrophies which may help in differential diagnosis.

Abstract
The ultrastructure of the avian Golgi tendon organ (GTO) is described and compared with those of mammals using transverse sections through the myo-tendinous junctions of wing muscles of adult mallard ducks. The capsule, which is continuous with the perineural epithelial sheath of the Ib afferent nerve fiber, consists of four to seven flattened cellular lamellae. Two to four muscle fibers attach to large collagen bundles which enter the GTO through a tight collar at the proximal end of the fusiform capsule. These collagen bundles divide into many smaller bundles, which run longitudinally through the lumen in compartments formed by septal cells. The septal cells contain many prominent lipid accumulations. The Ib axon divides several times, and the unmyelinated branch axons weave between the small collagen bundles. Schwann cell processes or basement membrane usually intervene between the axons and collagen bundles. The small collagen bundles regroup into larger bundles, which pass through tight capsular collars and merge with the main muscle tendon. The size of the duck GTOs was measured and found to be smaller than the GTOs of man, cat or rat.

Abstract
The structure and ultrastructure of 122 lamellated corpuscles and 33 Golgi tendon organs (GTO) from adult human musculotendinous junctions were studied by light microscope and electron microscope techniques. One Meissner corpuscle from a human fingertip was examined for comparison. At the musculotendinous junction the axon terminals of the GTO were observed in direct contact with the tendon collagen. The lamellated corpuscles were located in the connective tissue surrounding the musculotendinous junction. The axon terminals of the lamellated corpuscles were separated from the surrounding tissues by the inner core lamellar cell processes and the capsule layers. A great variation in the structure of both types of receptors was observed. The lamellated corpuscles that were found close to the musculotendinous junction and the GTO may respond simultaneously to muscular contraction, thus providing proprioceptive feedback for sensorimotor control from within the tendon and from the tissues surrounding the musculotendinous junction. Mechanoreceptors found in dermis, subcutaneous and deep tissues can be classified into 2 broad groups. This practical morphologic classification is based on the characteristics of the sensory nerve terminals which have been found to be in contact with the surrounding tissue (muscle spindle, GTO) or with the lamellar cell processes (Vater, Pacini, Meissner), rather than the inconsistent features of the entire receptor such as the size, the shape, or the encapsulation.

Abstract
We determined the total activity and isoenzyme distribution of lactate dehydrogenase and creatine kinase in serum and biopsy specimens from skeletal muscle of nine normal individuals and nine patients with Duchenne muscular dystrophy (I), five with collagen disease (II), and four with non-progressive unclassified myopathy (III). Mean total serum creatine kinase in patients with Duchenne muscular dystrophy (867 U/liter, SD = 197) was 31-fold that in the control group (28 U/liter, SD = 14). There was also a small (3.3-fold) increase in the mean total serum creatine kinase of patients with III, but none in the serum from patients with II. Changes in the creatine kinase isoenzyme distribution of skeletal muscle were primarily in the MB isoenzyme. The mean percentage of creatine kinase-MB activity in muscle from patients with I (2.81, SD = 1.15) and patients with III (1.69, SD = 1.07) significantly (P less than 0.005) exceeded that of the control group (0.43, SD = 0.18). Muscle from patients with II showed little change. The most striking changes in lactate dehydrogenase were also observed in patients with I, in whom the mean total serum activity (356 U/liter, SD = 115) was 3.4-fold that of serum from the control group (105 U/liter, SD = 19). Skeletal muscle from these patients also showed a significant decrease in mean percent isoenzyme 5 activity (from 50 to 23) and an increase in that of isoenzymes 1 and 2 (from 1 to 9 and 8 to 20, respectively). These changes in the distribution of these two sets of isoenzymes in muscle were reflected in the serum.

Abstract
The electromyogram (emg)-gas cystometrogram was used to study spinal-cord-injured patients with indwelling catheters before trial of voiding (TOV) to remove an indwelling catheter. Twenty-four patients were studied during 27 consecutive admissions. A coaxial needle electrode was placed in the external urethral sphincter. The output of a cystometer was simultaneously recorded on the emg printout so that the relationship of the shpincter response to distention of the bladder could be observed. Of 10 patients without bladder contractions, 7 had active urethral sphincters and 6 of these failed to achieve less than 50 ml residual thereby failing the TOV. The seventh patient succeeded in the trial and on subsequent study was found to have developed bladder contractions with a coordinated bladder-sphincter synergy. The 3 patients without bladder contractions or sphincter activity succeeded in their TOV using Credé's method. Seventeen patients with bladder contractions were divided into synergic, nonsynergic and partially synergic patterns. The 3 patients with synergic patterns succeeded in their TOV. Thirteen of 14 nonsynergic or partially synergic patients failed the TOV. The 1 nonsynergic patient who succeeded had bladder contractions of 70 cm of water compared to a mean of 28 cm of water for all other patients with bladder contraction. The emg-gas cystometrogram was helpful in selecting those patients who were successful in removing the Foley catheter. Important factors governing success in the multiple effort trial of voiding were the amplitude of the detrusor contraction, the presence of detrusor-sphincter synergy and the presence of a flaccid sphincter.

Abstract
Serum lactate dehydrogenase (LDH) isoenzymes were determined in 27 patients with collagen disease and 88 normal subjects. The mean value for LDH-3 isoenzyme was 20.4 +/- 3% in normal controls, 31.47 +/- 8.9% in patients with collagen disease who showed activity of the disease, and 20 +/- 3.74% in patients in complete remission. Six patients who had positive rheumatoid factor showed higher LDH-3 levels. There was also some correlation between the activity of the disease and serum LDH-3 level in patients with connective tissue disorders.

Abstract
Movement of the cervical spine in the sagittal plane was studied in ten normal subjects from 20 to 30 years of age without and with four different cervical orthoses: (1) polyethylene Camp plastic collar with chin and occiput piece, (2) plastizote Philadelphia collar, (3) four-poster and (4) SOMI (sternal occipital mandibular immobilization). The effect of the orthoses on restricting sagittal motion was measured simultaneously using roentgenographic and bubble goniometric methods. The subject was immobilized in a straight back chair to eliminate trunk motion, and lateral cervical spine films were taken of each subject in neutral, flexion and extension without and with each orthotic device. Distortion forces exerted on the orthotic devices were standardized by measurement of pressures at the chin and occiput. Roentgenographic measurements of flexion and extension and anteroposterior displacement of the cervical spine were compared to the measurements obtained by bubble goniometry. The four-poster and SOMI were found to be most effective in restricting extension and flexion respectively. The polyethylene and plastizote orthoses were significantly less effective in restricting motion. The bubble goniometer is an adequate clinical tool in assessing overall flexion-extension of the cervical spine but is not so precise and does not give information on the degree of motion at an individual vertebral level.
