This study aimed to compare the therapeutic efficacy and safety of dorzolamide/timolol fixed-combination(Cosopt) in newly diagnosed primary open-angle glaucoma (POAG) patients.In this prospective, interventional case series, newly POAG patients were included. Patients were started on Cosopt twice a day (BID) for one month and then switched to three times a day (TDS) for an additional month. Patients underwent comprehensive ophthalmic examination, diurnal intraocular pressure (IOP), blood pressure (BP), and 24-h heart rate (HR) measurements at baseline, month 1(BID), and month 2(TDS). Throughout the study, all adverse events were monitored by the investigators.In 31 POAG patients that completed the study, the mean baseline IOP was 23.1 ± 3.15 mmHg. IOP was decreased significantly 16.5 ± 2.21 at one month (p < .0001) and 13.9 ± 2.23 mmHg at 1 and 2 months follow up (p < .0001). IOP was significantly lower in month 2 compared to month 1 (p = .0004). While Cosopt BID significantly reduced the mean 24-h systolic BP and mean 24-h HR from baseline (p < .0001), the mean 24-h systolic BP and HR remained unchanged with Cosopt TDS compared to BID (p = .62).Cosopt TDS has a superior IOP-lowering effect than Cosopt BID in POAG patients with comparable safety profiles.
Intravitreal vascular endothelial growth factor (VEGF) inhibitor injection in patient during pregnancy
Kianersi F., Ghanbari H., Naderi Beni Z., Naderi Beni A.
To report the clinical course of a woman treated with intravitreal bevacizumab during pregnancy.A 27-year-old female with poorly controlled diabetes and a history of two previous miscarriage was referred to our hospital with sudden deterioration in visual acuity (VA) in her right eye. Ocular findings revealed severe Proliferative Diabetic Retinopathy (PDR) complicated with preretinal hemorrhages in her right eye, and after maximal Panretinal Photocoagulation (PRP) bilaterally, she was treated with intravitreal injection of bevacizumab (IVB) into the right eye. Twenty four hours after the bevacizumab injection, she reported vaginal bleeding, and ultrasound confirmed a 12-week pregnancy of which the patient was unaware. The patient suffered from pregnancy loss.Use of intravitreal anti-VEGF by pregnant woman may only be justified if the potential benefit outweighs the potential risk to the fetus and only if clearly needed. Intravitreal bevacizumab during pregnancy in women with a history of miscarriage should be used with caution.
Virtual screening for potential inhibitors of β(1,3)-D-glucan synthase as drug candidates against fungal cell wall
Farhadi Z., Farhadi T., Hashemian S.M.
Background: To enhance the outcome in patients with invasive candidiasis, initiation of an efficient antifungal treatment in a suitable dosage is necessary. Echinocandins (e.g. caspofungin) inhibit the enzyme β(1,3)-D-glucan synthase of the fungal cell wall. Compared to azoles and other antifungal agents, echinocandins have lower adverse effects and toxicity in humans. Echinocandins are available in injectable (intravenous) form. Methods: In this study, to identify the novel oral drug-like compounds that affect the fungal cell wall, downloaded oral drug-like compounds from the ZINC database were processed with a virtual screening procedure. The docking free energies were calculated and compared with the known inhibitor caspofungin. Four molecules were selected as the most potent ligands and subjected to hydrogen bonds analysis. Results: Considering the hydrogen bond analysis, two compounds (ZINC71336662 and ZINC40910772) were predicted to better interact with the active site of β(1,3)-D-glucan synthase compared with caspofungin. Conclusion: The introduced compound in this study may be valuable to analyze experimentally as a novel oral drug candidate targeting fungal cell walls.

Preparation and clinical evaluation of Finastride gel in the treatment of idiopathic Hirsutism
Tahvilian R., Ebrahimi A., Beiki O., Nemati H., Masoud S.
Hirsutism is the presence of excess terminal hairs in females in a male-like pattern. The most accepted hypothesis for the development of hirsutism is increased 5α-reductase activity in hair follicles of hirsute women. Finasteride partially blocks the conversion of testosterone to dihydrotestosterone through inhibition of 5α-reductase in hair follicles. This study was designed to determine the efficacy of finasteride gel 0.25% in management of idiopathic hirsutism and treatment of hirsutism with topical finasteride to lessen the side-effects.Women after puberty that have idiopathic hirsutism criteria are divided randomly in two groups; treatment and control. The number of patients in each group is 15 and received finasteride and placebo gel once a day on their skins. The patients were visited every month by a dermatologist and the amount of response to the treatment and the patient satisfaction was recorded. Ferriman-Gallwey score of the treated area was determined.After 6-months, mean thickness hairs in treating group were decreased from 102.00 ± 9.58 µm to 86.4 ± 11.4 µm (p < 0.05), this difference was statistically significant. Gel application did not indicate any type of side-effects.Inclusion and exclusion criteria.Finasteride partially blocks 5α-reductase. Because of the good absorption through the skin and good solubility of this medicine, the prepared gel formulation applied on the hirsutism area showed a significant decrease in hair growth locally, so finasteride gel is an efficient and harmless therapy in patients with idiopathic hirsutism.
