Transient intraocular lens opacification during phacoemulsification surgery.

J Curr Ophthalmol 2019 Sep 30;31(3):342-344. Epub 2018 Oct 30.

Isfahan University of Medical Sciences, Isfahan, Iran.

Purpose: To report an interesting case of intraoperative opacification of intraocular lens (IOL).

Methods: This study is a report of a 61-year-old male patient who suffered from nuclear sclerosis cataract and had undergone phacoemulsification surgery. During surgery, intraoperative opacification of IOL (Cristal, Cristalens), which was a foldable, 13 mm, one piece, square edge and hydrophilic acrylic IOL, occurred. This phenomenon caused a surprise and a decision to explant the IOL, but the surgeon decided to keep the IOL in place. After a day, it was completely clear.

Results: The surgery was completed successfully without any complications, and the IOL was completely clear the day after surgery.

Conclusion: Acute, transient IOL opacification with unproven etiology may occur during cataract surgery.

Clinical characteristics, histopathology, and treatment outcomes in adult and pediatric patients with nonspecific orbital inflammation.

J Curr Ophthalmol 2019 Sep 28;31(3):327-334. Epub 2019 Mar 28.

Eye Research Center, Farabi Eye Hospital, Tehran University of Medical Sciences, Tehran, Iran.

Purpose: To evaluate the clinical characteristics, histopathology, and treatment outcomes in adult and pediatric patients with nonspecific orbital inflammation (NSOI).

Methods: This retrospective study evaluates 76 patients with NSOI. The patients were categorized in 9 groups according to the site of involvement and histopathology results. These groups included: anterior involvement, dacryoadenitis, myositis, perineural involvement, acute fat involvement, focal mass, orbital apex involvement, diffuse sclerosing form, and multiple tissue involvement. The course of the disease was categorized as acute, subacute, or chronic. The cases with symptom duration of less than 1 week were classified as acute, 1 week to 1 month as subacute, and more than 1 month as chronic.

Results: 36 (47.4%) patients were males. The mean age was 41.68 ± 17.62 (6-75) years. The most common signs and symptoms were periorbital pain, periorbital edema, decreased ocular movements or diplopia, and conjunctival injection. The most common group was dacryoadenitis in 29 (38.1%) cases. The most common form of disease was the acute involvement (50% of patients). Most of the patients were treated by oral corticosteroids. Duration of follow-up was 7.17 ± 6.26 months. Recurrence occurred in 9 (11.8%) of patients during the follow-up period.

Conclusions: This study presents a new categorization in which multiple tissue involvements were separated. Some of the NSOI features differ between adults and children. In most patients, treatment especially with corticosteroids, resolves the clinical findings.

Orbital invasion of ameloblastoma: A systematic review apropos of a rare entity.

J Curr Ophthalmol 2018 Mar 6;30(1):23-34. Epub 2017 Nov 6.

Isfahan Eye Research Center, Feiz Hospital, Isfahan University of Medical Sciences, Isfahan, Iran.

Purpose: Ameloblastoma is a non-encapsulated and slow-growing tumor with high recurrence rate. Orbital involvement by this neoplasm is an extremely rare entity. In this study, we present a systematic review on this situation along with clinical and paraclinical features of a case.

Methods: An electronic search was conducted on major medical sources. Data of the cases in the literature in addition to our own case were extracted, summarized, and statistically analyzed.

Results: A total of 36 other cases from 20 relevant studies were also reviewed. Review topics included epidemiology, clinical presentation, pathologic features, differential diagnosis, imaging, treatment, and prognosis. We provided a five-year history of a 50-year-old man with orbital/skull base invasion of plexiform maxillary ameloblastoma.

Conclusions: Maxillary ameloblastoma is a locally aggressive neoplasm, and physicians must be alert to the biologic behavior of this tumor to detect any invasion to critical structures such as orbit and cranium. Orbital ameloblastoma causes significant morbidity and mortality. We advocate meticulous patient follow-up with regular clinical examinations and paraclinical work-up for timely detection of any invasion or recurrence. The best must be done to avoid extensions by aggressive removal of maxillary ameloblastoma.

Comparison of Scheimpflug and swept-source anterior segment optical coherence tomography in normal and keratoconus eyes.

Int Ophthalmol 2017 Aug 26;37(4):965-971. Epub 2016 Sep 26.

Biostatistics and Epidemiology Department, Isfahan University of Medical Sciences, Isfahan, Iran.

Purpose: The purpose of the study was to assess the agreement of anterior segment optical coherence tomography with its older well-known opponent i.e., Sheimpflug imaging in evaluation of the cornea in normal and keratoconus subjects.

Methods: 107 normal and 56 keratoconus eyes were evaluated with the anterior segment optical coherence tomography followed by the Scheimpflug imaging. Parameters included axial keratometry data in both of steep and flat meridians, mean keratometry and the astigmatism values in the central 4.0 mm zone, central, thinnest and apex corneal thicknesses, Q-value in 8 mm zone and pupil diameter. Corneal topographic maps were recorded and were evaluated for anterior highest and lowest points, posterior highest and lowest points. Average values were recorded for analysis.

Results: All anterior cornea keratometry indices showed perfect agreement between two devices in normal corneas; while the level of agreement in keratoconus cases ranged from moderate to strong. All posterior keratometry indices also showed perfect agreement in both groups; except for flat K in normal corneas and steep K in KC ones. The amount of corneal cylinder in normal corneas had perfect agreement, and moderate to strong agreement in anterior/posterior cornea in keratoconus group. Anterior highest and lowest points showed strong and perfect agreement in normal and keratoconus cases, respectively. Posterior highest and lowest points showed strong agreement in normal cases. Thickness indices (central, thinnest, and apex thicknesses) showed perfect agreement between two devices in both normal and KC groups. Mean values of anterior and posterior highest points were statistically higher in Scheimpflug system.

Conclusions: Although two imaging technologies had statistically numerical different output, it seems that they have a good agreement in most parameters.

Intravitreal Diclofenac plus Bevacizumab versus Bevacizumab alone in treatment-naive diabetic macular edema: a randomized double-blind clinical trial.

Int Ophthalmol 2017 Aug 13;37(4):867-874. Epub 2016 Sep 13.

Isfahan Eye Research Center (IERC), Feiz Hospital, Isfahan University of Medical Sciences, Isfahan, Iran.

The aim of this study is to evaluate the short-term effects of a single intravitreal injection of 1.25 mg Bevacizumab combined with 300 lg/0.1 mL Diclofenac (IVB/D) versus 1.25 mg intravitreal Bevacizumab (IVB) alone in the treatment of naive diabetic macular edema (DME). In this prospective, randomized clinical trial, 80 eyes were included in the final analysis; 42 and 38 of which in the IVB and IVB/D groups, respectively. The primary outcome measure was a change in best-corrected visual acuity (BCVA) in logMAR at week 4. The secondary outcomes included changes in central macular thickness (CMT), macular volume, and potential injection-related complications. Significant improvement of BCVA was demonstrated in both study arms (mean reductions in LogMAR: -0.088 ± 0.278, -0.228 ± 0.330 for IVB and IVB/D, respectively). The difference in BCVA changes was in favor of IVB/D; however, not to a statistically significant level (P = 0.160). Significant reduction of CMT was documented in both study arms (mean reductions: 82.43 ± 160.09 and 153.26 ± 163.85 for IVB and IVB + IVD, respectively). Comparison of CMT changes between groups showed that IVB/D reduced CMT more than that of IVB (P = 0.04). Effects on macular volume corresponded to those of CMT. No injection-related complications or significant alterations in intraocular pressure were observed in any of the study arms. In treatment-naive DME, superiority of IVB/D combination therapy over IVB monotherapy may exist; especially as regards anatomical features. In our therapeutic arsenal for DME, IVD can be added as an adjunct to Bevacizumab.

Transposition surgery for WEBINO.

Int Ophthalmol 2017 Feb 20;37(1):271-274. Epub 2016 Apr 20.

Ophthalmology Department, Isfahan University of Medical Sciences, Isfahan, Iran.

Wall-eyed bilateral internuclear ophthalmoplegia (WEBINO) is a rare syndrome which is characterized by a set of ocular motility abnormalities, especially a large-angle exotropia in primary gaze. One of the management strategies suggested for it is extraocular muscle surgery, particularly transposition surgery. In this 38-year-old male WEBINO patient, we concluded that transposition surgery could effectively alleviate the exodeviation and also the patient's complaints in comparison with resection-recession procedures.

Endothelial Function in Patients with Migraine without Aura during the Interictal Period.

Int J Prev Med 2015 15;6. Epub 2015 Jan 15.

Department of Neurology, Isfahan University of Medical Sciences, Isfahan, Iran.

Background: In most of the studies, the association of vascular events is limited to migraine with aura or it is stronger in this group, whereas the link between migraine without aura (MO) and vascular events remained uncertain. Therefore, we decided to evaluate endothelial function by chemical and functional markers of endothelium in MO and compare with normal population.

Methods: In this study, 39 patients and 25 healthy subjects were enrolled and flow-mediated dilatation (FMD), C-reactive protein (CRP), nitrite and nitrate were measured in these two groups.

Results: The mean of FMD in healthy people was higher than the migraine patients (mean difference - 7.67%; 95% confidence interval [CI] -9.90--5.44). The means of nitrite concentration in migraineurs was significantly lower than healthy subjects (mean difference - 2.0 μmol/L; 95% CI - 3.45--0.54). But the CRP concentrations in both groups were not significantly different (mean difference 0.42 pmol/L; 95% CI - 0.13-0.98).

Conclusions: This study can show the endothelial dysfunction in migraineurs without aura and suggest that MO could also be a risk for cardiovascular disease.

Evaluation of relationship between breast cancer and migraine.

Adv Biomed Res 2015 6;4:14. Epub 2015 Jan 6.

Isfahan Neuroscience Research Center, Isfahan University of Medical Sciences, Isfahan, Iran.

Background: Frequency of migraine changes at different times of a woman's reproductive cycle because of fluctuation of estrogen levels. Breast cancer has also a link with hormonal changes. Given this fact that both migraine and breast cancer are affected by estrogen, the prevalence of migraine may be different in breast cancer patients compared to the normal population.

Materials And Methods: In this case-control study, two groups of women with and without breast cancer were compared regarding the prevalence of migraine. Each group consisted of 400 women. The diagnosis of different types of headache was made based on The International Headache Society (IHS) guidelines. Type of headache, type and receptor status of breast cancer, as well as history of taking hormonal medications was recorded. Independent t-test and Chi-square tests were used for data analysis.

Results: Relative frequency of migraine headache in the normal woman was 38% compared to 19% in the breast cancer group (P < 0.0001). Tension headache was also significantly more prevalent in the normal group (P < 0.001). The frequency of migraine was significantly lower in estrogen receptor (ER)+/progesterone receptor (PR)- women compared to ER-/PR+ (26 and 43 women, respectively; P = 0.04); however, this difference was not significant for tension headache (P = 0.68).

Conclusion: This study confirmed the lower frequency of migraine, as well as tension headache, in breast cancer sufferers. This could be contributed to several non-hormonal factors, such as a history of long term use of nonsteroidal anti-inflammatory drugs (NSAIDs), and hormonal factors, although only migraine showed a strong link with hormone status.

A rare anomalous origin of left subclavian artery from the circle of Willis in combination with right sided aortic arch: A case report.

ARYA Atheroscler 2013 Sep;9(5):303-5

Assistant Professor, Isfahan Cardiovascular Research Center, Isfahan Cardiovascular Research Institute, Isfahan University of Medical Sciences, Isfahan, Iran.

Background: One of the rare aortic congenital abnormalities is right sided aortic arch which is occurred in approximately 0.1% of the population. The anomalous origin of the subclavian arteries has also been reported.

Case Report: In this study, a case of a right-sided aortic arch with anomalous left subclavian artery origin from the cerebral arteries is presented which was diagnosed in Computed tomography angiogram (CT angiogram) and angiography of a 10-year-old boy referred due to recurrent chest pains during two weeks before admission and pulselessness of his left upper limb and left carotid artery.

Conclusion: Many of the congenital vascular anomalies may have no obvious signs or symptoms and therefore the exact history and physical examination could help us in better diagnosis. Besides, some of these anomalies are associated with other abnormalities of other body organs particularly the cardiac system.

Efficacy of Enalapril in Migraine Prophylaxis: A Randomized, Double-blind, Placebo-controlled Trial.

Int J Prev Med 2013 Jan;4(1):72-7

Isfahan Neuroscience Research Center, Isfahan University of Medical Sciences, Isfahan, Iran.

Background: Some angiotensin converting enzyme (ACE) inhibitors have previously been shown to be effective in migraine prophylaxis. The aim of this study was to evaluate whether Enalapril is effective in migraine prophylaxis.

Methods: In this randomized, double-blind, placebo-controlled clinical trial, the effects of 10 mg Enalapril given daily were compared with those of matched placebo in 40 migraineurs for 2 months. Response to treatment was assessed at 0, 1, and 2 months after the start of intervention according to headache parameters like frequency, severity, and duration. This trial is registered with Iranian Registry of Clinical Trials (IRCT), number IRCT138711011570N1.

Results: A significant effect on reducing migraine attack more than 50% at first and second months (P=0.016) occurred in Enalapril group. Indeed, at the first and second months of treatment, the severities (P=0.000 and P=0.000) and duration (P=0.037 and 0.003) in the Enalapril treated group were significantly lower than in the placebo group.

Conclusion: Enalapril may be effective in migraine prophylaxis according to its effect in decreasing the frequency, severity, and duration of headaches. The results support the previous suggestions on usage of ACE inhibitors in migraine prophylaxis.

The course and outcome of pregnancy and neonatal situation in epileptic women.

Adv Biomed Res 2012 28;1. Epub 2012 Mar 28.

Department of Neurology, Alzahra Hospital, Isfahan, Iran.

Background: Epilepsy is a rare neurologic disorder during pregnancy. Despite its rarity, it could cause different clinical problems in this natural phenomenon of a woman's life. The aim of this study was to evaluate and compare the course of pregnancy and labor and their outcome in epileptic and healthy women.

Materials And Methods: This study was performed during years 2009--2011 in Alzahra and Beheshti hospitals affiliated to Isfahan University of Medical Sciences. A total of 51 pregnant women, who were known cases of epilepsy and were on antiepileptic drugs treatment for at least 3 months, were compared with 47 matched healthy pregnant women without epilepsy. They were followed before and during their pregnancy in several visits and all of their neurologic and obstetric information were collected. For statistical analysis of continuous variables, the t-test was used. The chi-square test was used for dichotomous variables.

Results: The rate of monotherapy was more than polytheraphy especially during the pregnancy. The epileptic attacks stopped in majority of patients during the pregnancy. Vaginal bleeding (P=0.020) and abortion (P=0.015) were significantly more frequent among epileptic mothers. The gestational age was lower meaningfully (P= 0.010) in epileptic patients' neonates and the first minute Apgar score was lower in these babies too (P=0.028).

Conclusions: Antiepileptic drugs could have some unsuitable effects on pregnancy course especially by increasing the rate of abortion, preterm labor, and vaginal bleeding. Their adverse effects on neonates' health could not be neglected.

Enalapril improves endothelial function in patients with migraine: A randomized, double-blind, placebo-controlled trial.

J Res Med Sci 2011 Jan;16(1):26-32

Applied Physiology Research Center, Isfahan University of Medical Sciences, Isfahan, Iran.

Background: There are increasing evidences of endothelial dysfunction in migraine. The ACE-inhibitors have previously been shown to be effective in migraine prophylaxis. Furthermore, ACE inhibitors have beneficial effects on endothelial dysfunction. We therefore investigated whether Enalapril is effective in endothelial function improvement.

Methods: In this randomized clinical trial, 10 mg Enalapril daily was compared with matched placebo in 40 patients with migraine for two months. Flow Mediated Dilation (FMD), serum total nitrite and C-reactive protein (CRP) were measured in all patients at the baseline and after 2 months.

Results: patients' FMD increased in the case group after treatment with Enalapril (p = 0.002) while there was no significant change in control group. Total nitrite concentration increased in case group (p = 0.000), while there was no significant difference before treatment. There was no significant difference in the CRP concentrations in two groups.

Conclusions: These results indicate that ACE inhibition can improve endothelial function in patients with migraine, as it has been shown by both FMD and serum levels of nitric oxide. The mechanism could be either that Enalapril limits the angiotensin IIinduced production of superoxide radicals which would normally inactivate nitric oxide, or that it may increase bradykinin-mediated nitric oxide release.
