INTRODUCTION: Acetazolamide as inhibitor of carbonic anhydrase, in glaucoma therapy, has an effect on lowering intraocular pressure. In addition to this primary effects, we attempted to determine the effect on the cornea after phacoemulsification. In our study, we determined the effects of systemically applied dose of 500 mg of acetazolamide on the edema, thickness, and corneal morphology after phacoemulsification, with the Anterior Segment Optical Coherence Tomography (AS OCT). MATERIAL AND METHODS: The study included 53 patients who were divided into two groups. Groups were stratified by type of cataract (nuclear), age (62+1.5), preoperative visual acuity (5/60) Snellen table, and preoperative findings on AS-OCT. Phacoemulsification has done the same surgeon, with the same ultrasound probe length using ultrasonic force of the average value of 14 for a period of 72+2.5 seconds. Group of 33 patients were administered systemic acetazolamide at a dose of 250 mg per scheme 01 hours +24 hours after phacoemulsification (group I). Another group of 20 patients did not receive acetazolamide( group II). AS OCT recordings were performed before surgery, 6 hours and 24 hours after surgery. RESULTS: The mean value in both groups was 549+ 9 ?m before surgery. Group I had average value of 648+6 ?m after 6h, and the mean value was 612+4 ?m after 24h. The group II, had a mean thickness of the cornea after 6 hours of 720+5 ?m, and after 24 hours 708+4?m. Morphological changes in the tomograms of the group I showed minimal creases Descemet?s membrane. Postoperative visual acuity was 0,6,24h after the surgery in the I group of patients, and 0,3 in the II group. CONCLUSION: In our study the patients who administered systemic acetazolamide had significant reduction of central corneal thickness. The folds of Descemet?s membrane and endothelial dysfunction in AS OCT tomograms showed less structural changes in group I. Significant better postoperative visual acuity in these patients is probably because of the smaller corneal edema after 24 h, which improves patients? comfort.

Functional TLR4 expression has been linked to HCC development. TLR4 may serve an important role in HCC development by promoting the malignant transformation of epithelial cells and tumor growth. The consequences might be dependent on the complex signaling networks triggered by TLR4 activation and the tumor microenvironment. The study included 90 consecutive subjects classified into 3 group their age from 40 to 70 years old. Group (I): HCC patients on top of chronic HCV infection. they were 45 patients 30 male and 15 females, their age ranged from 45 to 55 who were subdivided into 3 subgroups according to Barcelona clinic liver cancer (BCLC): Group (Ia): included 8 HCC patients in early stage. (stage A). Group (Ib): included 12 HCC patients in intermediate stage (stage B). Group (Ic): included 25 HCC patients in advanced stage. (stage C). Group (II): 30 Cirrhotic patients with chronic HCV, 21 male and 9 females, their age ranged from 50 to 60. This group was subdivided into 2 subgroups according to Child–Pugh score Group (IIa): included 8 Child–Pugh A. Group (IIb): included 22 Child–Pugh B and C. Group (III): controlled group included 15 normal subjects. 10 male and 5 females, their age ranged from 45 to 60. They were selected to match patients’ groups in demographic and socioeconomic standards. In our study where 15 persons are control showed lower level in TLR4 with mean 1.0±0.2, however 30 patients with HCV and other 45 patients with HCC showed higher level in TLR with mean 2.27±0.6 and 4.2±1.06 respectively. In our study there is statistically significant difference in serum TLR4 level between group (Ia) (2.25±0.5) and other subgroups which shows more increase in serum level of TLR4 in Group IB (3.2-1.06) than Group IA. Also shows more increase in serum level of TLR4 in Group IC (4.0±2.0) than Group IA and IB In our study HCC group showed higher level of LPS with mean 4.5±1.26 however lower in HCV group with mean 2.9-1.0 and least in control group with mean 1.1±0.4 In our study there is statistically significant difference in serum LPS level between group (IA) with mean 3.0±0.5 and other subgroups which shows more increase in serum level of LPS in Group IB with mean 4.4-1.0 than Group IA. Also shows more increase in serum level of LPS in Group IC with mean 4.0±1.76 than Group IA and IB In our study there is statistically significant difference in serum LPS level between group (IIB) and group (IIA) which shows more increase in serum level of TLR4 in Group IIB with mean 2.7±1.1 than Group IIA with mean 2.20±0.2 In our study there is statistically insignificant difference of the mean value ± SD of sex as regard to LPS and TLR expression (t = 1.2, p = 0.22). (t = 0.16, p = 0.87) respectively.In our study there is statistically significant positive correlation between ALT, AST, Platelets, alpha fetoprotein and LPS as regard to TLR4 expression in group II more in IIB,C than IA . but insignificant of the mean value ± SD of other parameters.

To compare the efficacy of intravenous methylprednisolone and intravenous dexamethasone for the treatment of optic neuritis in terms of visual recovery and side-effects and to evaluate the clinical profile of optic neuritis patients admitted in BPKLCOS. 60 patients of acute idiopathic typical optic neuritis presenting to our centre were included in this prospective, randomized comparative study. Study population was randomly divided into two groups. Group I received intravenous dexamethasone 200 mg once daily for three days and Group II received intravenous methylprednisolone 500 mg/twelve-hourly for three days followed by oral prednisolone for 11 days. Optic neuritis was found to be common in the age group of 21 to 30 years with female preponderance. The most frequent mode of presentation was abrupt loss of vision. Retrobulbar optic neuritis dominated the study group. Both groups were age and sex-matched. The mean presenting visual acuity in group I was 0.065±0.59. The mean presenting visual acuity in group II was 0.1±0.15. On day 90 of steroid therapy, visual acuity improved to 0.98±0.073 in Group I and 0.88±0.16 in Group II (p=0.23). At three months, there was statistically significant improvement in both groups in terms of colour vision, contrast sensitivity and Goldmann visual fields as well but difference between the two groups was statistically insignificant. Intravenous dexamethasone is an effective treatment for optic neuritis, which is comparable to intravenous methylprednisolone. However, larger studies are required to establish it as a safe, inexpensive and effective modality for the treatment of optic neuritis.

Purpose To investigate the adjunct efficacy and safety of vitamin supplements, including resveratrol, in patients with diabetic macular edema (DME) treated with intravitreal anti-vascular endothelial factor (anti-VEGF) agents. Methods Participants in this prospective study were 45 patients with DME, who were treated with either intravitreal anti-VEGF injections (n = 23, Group I) or with combination of intravitreal anti-VEGF injections and vitamin supplements, including resveratrol (n = 22, Group II). All patients underwent visual acuity measurement, slit-lamp examination and spectral domain-optical coherence tomography (SD-OCT) at baseline and monthly after the loading phase of three-monthly anti-VEGF injections, following a PRN protocol. Results There was a statistically significant improvement in visual acuity in both groups at month 12 compared to baseline, although the mean change in visual acuity did not differ between the two groups (p = 0.183). Accordingly, there was a statistically significant decrease in central retinal thickness in both groups at month 12 compared to baseline, while the mean difference in central retinal thickness was significantly greater in the “combination” group. The mean number of intravitreal anti-VEGF injection was less in Group II (6.45 ± 1.12 in Group II vs. 7.39 ± 1.31 in Group I, p = 0.018). Conclusions Vitamin supplements with resveratrol was found to be an effective adjunct to intravitreal anti-VEGF injections in patients with DME, offering better anatomic restoration with less injections at the 12-month follow-up.

The purpose of this study is to determine the association of speaking space of /s/ sound with vertical and horizontal overlaps for two subject groups. Group I comprised 61 subjects with complete permanent dentition and Group II comprised 33 complete denture wearers. They had their mandibular movement determined by using an electromagnetic method. Speaking space of /s/ was obtained from each subject as they were instructed to say the word 'seis' three times. The mean interocclusal distance during /s/ production was considered the speaking space of /s/. Vertical and horizontal incisor overlaps were also measured. The mean value of speaking space of /s/ was 2.22 mm (± 1.38) for Group I and 2.61 mm (± 1.53) for Group II. In Group I, significant correlations were found between the speaking space of /s/ and vertical overlap (r=0.36, P<0.01), and between speaking space of /s/ and horizontal overlap (r=0.45, P<0.01). In Group II, no significant correlation was found between speaking space of /s/ and the overlaps. It was concluded that incisor overlap had a direct influence on the measure of speaking space of /s/ for dentate subjects, but this association was not present for complete denture wearers.

Purpose: To investigate the safety of laser epithelial keratomileusis (LASEK) by drawing a comparison between two groups divided according to age (18-19 vs. 20-21 years old).Methods: The study was conducted as a retrospective analysis including 339 patients (678 eyes) who underwent LASEK between January 2017 and April 2020. Patients were divided by age group, group I (18-19 years old) and group II (20-21 years old). The objectives of the study included determination of visual acuity and refractive errors before and at 1, 3, and 6 months after the procedure.Results: The preoperative mean spherical equivalents (SEs) were -4.73 ± 0.88 diopters (D) in group I and -4.58 ± 0.87 D in group II (p = 0.34). At 1 month postoperatively, mean SEs were 0.32 ± 0.46 D in group I and 0.26 ± 0.59 D in group II (p = 0.18). At 3 months postoperatively, the mean SEs were 0.30 ± 0.47 D in group I and 0.28 ± 0.50 D in group II (p = 0.67). At 6 months postoperatively, the mean SEs were 0.15 ± 0.47 D in group I and 0.14 ± 0.50 D in group II (p = 0.89). There were no significant differences in postoperative best corrected visual acuity between group I and group II at 1, 3, or 6 months (p = 0.20, p = 0.13, and p = 0.11, respectively).Conclusions: There were no significant differences in postoperative mean SE or safety of LASEK between moderate myopia patients 18-19 years old and those 20-21 years old.

The aim of this study was to evaluate the effect of Altresyn® product (progesterone-based product) as a method for synchronization of oestrus in gilts. The gilts were divided into three experimental groups. The synthetic progesterone Altrenogest was fed daily to 39 gilts at 20 mg/gilts for 18 days. In case of the first group (n = 11 gilts) the treatment was performed using only Altresyn product. In group II (n=13 gilts) was administered the prostaglandin hormone (Prosolvin), 0.75 mg at 24 hours after Altrenogest treatment suppression. Group III (n=15 gilts) received one injections of PMSG hormone (Folligon), 500 IU/animal. Gilts were checked for oestrus twice daily and were artificially inseminated. All gilts expressed signs of oestrus between 3 and 6 days after withdrawal of Altrenogest. At the groups that were administered prostaglandin and PMSG there was a shorter duration of oestrus (group III - 26.66 hours, group II - 27.07 hours) compared to group I (28.54 hours).  In this study, pregnancy rate ranged from 45.45% (group I) and 93.33%(group III), while in group II the value slightly exceeded 50% (53.84%). In group I, the mean litter size was 11.6 piglets, in group II the mean value of farrowed piglets was 13.28 and 15 piglets in group III. Regarding the average number of weaned piglets in group I was 8.8, 12 in group II, while for the third group was 13.14. Altrenogest, the active ingredient in Altresyn® is effective for regulating the oestrus of gilts in commercial pig farms.

Background: CIN has gained increased attention in the clinical setting, particularly during cardiac intervention but also in many other radiological procedures in which iodinated contrast media are used. There is at present good clinical evidence from well-controlled randomized studies that CIN is a common cause of acute renal dysfunction.Methodology: This was a prospective study conducted among the patients who underwent coronary angiography and percutaneous coronary intervention in the Department of Cardiology, Dhaka Medical College Hospital during January 2010 to December 2010. A total of 111 patients age range from 25 to 75 years were included in the study. Serum creatinine level at baseline and at the end of 48 hours was done in all these patients. Study population was divided into two groups according to development of acute kidney injury (AKI). Group-I = AKI, Group II = Not developed AKI. Results: AKI developed 11.7% of the study patient. DM and Preexisting renal insufficiency were significantly higher in group I patients. HTN was (61.5% Vs 44.9%) higher in group I but not significantly. History of ACE inhibitor/ARB, NSAID intake and LVEF <40% were significantly higher in group I patients. The mean±SD volume of CM (Contrast Media) were 156.9±44.8 ml and 115.4±30.0 ml in group I and group II respectively, which was significant. The mean±SD of serum creatinine after 48-72 hours of CAG/PCI was 1.4±0.37 mg/dl and 1.1±0.2 mg/dl in group I and group II respectively. The serum creatinine level increased significantly (p<0.05) after 48-72 hours of CAG/PCI in group I. In group II, S. creatinine level increased but not significant (p>0.05). Impaired renal function was found 76.9% and 2.0% in group I and group II respectively. DM, HTN, preexisting renal insufficiency, ACE inhibitor/ARB, NSAIDs, contrast volume (>150 ml), eGFR (<60 ml/min/ 1.73m2) and LVEF (<40%) are significantly (p0.05) associated for CIN development.Conclusion: CIN is an iatrogenic but preventable disorder results from the administration of contract media. Although rare in the general population, CIN occurs frequently in patients with underlying renal dysfunction and diabetes. In patients with pre angiographic normal renal function, the prevalence is low but in pre-existing renal impairment it may pose a serious threat. Thus risk factors are synergistic in their ability to predispose to the development of CIN. A careful risk-benefit analysis must always be performed prior to the administration of contrast media to patients at risk for CIN.

Abstract Background and aims: Gestational diabetes represents a form of diabetes diagnosed during pregnancy that is not clearly overt diabetes. In the last trimester of gestation the growth of fetoplacental unit takes place, thus maternal hyperglycemia will determine an increased transplacental passage, hyperinsulinemia and fetal macrosomia. The aim of our study was that o analyzing the effect of maternal glycemia from the last trimester of pregnancy over fetal weight. Material and method: We run an observational study on a group of 46 pregnant women taken into evidence from the first trimester of pregnancy, separated in two groups according to blood glucose determined in the third trimester (before birth): group I normoglycemic and group II with hyperglycemia (>92mg/dl). Results: The mean value of third trimester glycemia for the entire group was of 87.13±22.03. The mean value of the glycemia determined in the third trimester of pregnancy was higher in the second group (109.17 mg/dl) in comparison to the first group (74.,21 mg/dl). The ROC curve for third trimester glycemia as fetal macrosomia appreciation test has an AUC of 0.517. Conclusions: Glycemia determined in the last trimester of pregnancy cannot be used alone as the predictive factor for fetal macrosomia.

Purpose: To evaluate the long term visual, refractive, and corneal tomographic outcomes of epithelium-off accelerated corneal collagen cross-linking (ACXL) in the management of pediatric keratoconus (KC). Methods: This retrospective study included patients under 18 years old with progressive KC who underwent ACXL between 2012 and 2019 at Dicle University Hospital. Complete ophthalmic examination was performed including uncorrected distance visual acuity (UDVA), best spectacle-corrected distance visual acuity (CDVA), manifest refraction, and corneal tomography. Evaluations were performed preoperatively and at 6 months intervals postoperatively. Results: Forty-nine eyes of 49 patients were included in the study. The mean age of patients at the time of ACXL was 14.2 ± 1.8 (range: 9.5–17.3) years. Mean follow up was 4.61 ± 1.90 (range: 2.0–8.1) years. The mean LogMAR UDVA improved from 0.94 ± 0.41 to 0.81 ± 0.43, 0.69 ± 0.41, and 0.67 ± 0.33 after 1, 3, and 5 years respectively ( p = 0.001). The mean LogMAR CDVA improved from 0.58 ± 0.36 to 0.46 ± 0.31, 0.34 ± 0.23, and 0.39 ± 0.27 after 1, 3, and 5 years respectively ( p = 0.015). The mean refractive cylinder improved significantly from 6.01 ± 2.07 diopters (D) to 5.46 ± 1.87, 5.38 ± 2.18, and 5.02 ± 2.31 D after 1, 3, and 5 years respectively ( p = 0.005). As compared to preoperative values, steep keratometry and maximum keratometry were not significantly different ( p = 0.805 and 0.448, respectively) following ACXL, while flat keratometry significantly improved after ACXL ( p = 0.012). Although central corneal thicknesses decreased significantly ( p = 0.029), the decrease in thinnest corneal thickness was not statistically significant ( p = 0.205). Conclusion: Epithelium-off ACXL seems to be effective for halting KC progression with long term clinical benefits in pediatric patients.

Background: Labor is a naturally occurring physiological process associated with uterine contractions, effacement, dilatation of cervix and descent of presenting part. Drotaverine hydrochloride is a non-anticholinergic isoquinoline derivative which acts by elevating intracellular cyclic Adenosine Mono Phosphate (cAMP) and cyclic Guanosine Mono Phosphate (cGMP) promoting smooth muscle relaxation. Materials and Method: This was a hospital based prospective study on effectiveness of Drotaverine Hydrochloride on enhancing dilatation of cervix and acceleration of active phase of labor. The sample size was 100. Fifty cases of women in active phase of labor received injection drotaverine hydrochloride 40 mg (group i) and fifty cases of women did not receive any drug (group ii) among those at term with singleton pregnancy and vertex presentation. Variables like maternal age, interval between administration of drug and delivery, mode of delivery, apgar score at 5 minutes, NCU (Neonatal Care Unit) admission and neonatal outcomes were recorded. Data analysis was done with the help of SPSS program. Results: The mean interval between drug administration to delivery in primipara and multipara in group i was 3.05 hours and 2.31 hours while in group ii was 4.5 hours and 3.75 hours respectively. The mean interval between drug administration and delivery was shorter in both groups of multipara. In group i, 96% had normal delivery and 4 % had vacuum delivery and in group ii 90% and 10% had normal delivery and vacuum delivery respectively. None of the participants had caeserian section. There were no perinatal mortalities. Conclusion: The administration of drug Drotaverine Hydrochloride is effective in shortening duration of labor with favorable feto-maternal outcome.
