Background and Objective: Evaluating the agreement among various corneal imaging devices is crucial due to their varying technologies in diagnosing corneal parameters. This study aimed to assess the agreement of Advanced Corneal Explorer (ACE) with Pentacam and Orbscan in myopic individuals with healthy corneas.
Methods: This descriptive-analytical study was conducted on 45 myopic individuals (25 women and 20 men; mean age=30.37±6.13 years) referring to Al-Zahra Ophthalmology Hospital in Zahedan, Iran, during 2023. Anterior segment imaging was performed using three devices: ACE, Pentacam, and Orbscan. Corneal parameters, including topography, tomography, and corneal aberrations, were examined. The intraclass correlation coefficient (ICC) and 95% limits of agreement (LoA) were used to evaluate the agreement of ACE data with the data obtained from the other two devices.
Results: ACE exhibited good agreement with Pentacam for the mean power (ICC=0.97), maximum power (ICC=0.98), and minimum power of the anterior corneal surface (ICC=0.97) (P<0.05). Additionally, ACE exhibited good statistical agreement with Orbscan for the mean power of the anterior corneal surface due to an ICC of 0.98 (P<0.05). The ICC values for central corneal thickness and thinnest corneal thickness with the ACE and Pentacam devices were 0.99 and 0.95, respectively, indicating significant statistical agreement (P<0.05). White-to-white distance, pupil size, and corneal aberrations did not show good agreement among the three devices (ICC<0.75).
Conclusion: Topography values and corneal thickness measured with ACE showed good agreement with Pentacam; therefore, they can be used interchangeably. Other measured variables from ACE did not show good agreement with Pentacam and Orbscan and are not interchangeable.

The preservation of mahramiyyah (permissibility) in medical examinations has always been a challenging issue from the perspective of fiqh (Islamic jurisprudence). This matter becomes particularly significant in cases where medical necessities conflict with religious rulings. This analytical-research study, with a comparative approach, was conducted to provide a new framework to establish a balance between medical necessities and fiqh rulings. First, the theoretical foundations and research background were first extracted using reliable library sources, fiqh texts, and scholarly medical books and articles. Sources were searched in the following databases: PubMed, Scopus, Web of Science, Scientific Information Database (SID), Magiran, NoorMags, the Computer Research Center of Islamic Sciences (Noor), and the Comprehensive Jurisprudence Database. The keywords used included “Medical Mahramiyyah,” “Medical Fiqh,” “Medical Necessity,” “Non-Same-Sex Examination,” “Patient Privacy,” “Islamic Telemedicine,” and “Medical Religious Rulings” in Persian, English, and Arabic. Selected sources spanning the period during 1981-2024 were evaluated. The inclusion criteria comprised direct relevance to the topic, peer review, and appropriate content quality. The exclusion criteria included irrelevance to the topic, non-peer reviewed, replicate sources, studies with low quality or without valid data, public or news reports lacking scientific basis. Ultimately, 37 sources were selected and analyzed based on thematic analysis and fiqh deductive reasoning to identify common principles and points of conflict between the fiqh data and medical requirements. Emerging challenges in medical fields, such as telemedicine, were also evaluated. Although the primary principle in Shia fiqh is the prohibition of looking at (except for the face and hands up to the wrist) and touching a person of the opposite sex, whether for treatment or otherwise, there is a consensus among faqihs (Islamic jurists) that, in cases of necessity, this principle is suspended. As a result, examinations requiring touching and looking, even of the genitals, by a physician of the opposite sex are permissible. In both fiqh and medicine, necessity is defined as an urgent need for treatment or medical procedures that, if not performed, could lead to a serious threat to the patient's health. However, some faqihs, based on the rational rule of “Irtikāb Aqall al-Qabīḥayn” (committing the lesser of the two detestable things), deem direct touch and direct viewing to fall under the primary prohibition in instances where telemedicine and indirect examinations suffice for the aforementioned necessity. This research offers practical solutions to maximize the preservation of mahramiyyah in medical examinations, aiming to improve the quality of medical services in Islamic societies while adhering to religious principles.
 

Background and Objective: Chlamydia, a zoonotic bacterial agent, is a major concern for both human and avian public health. This bacterium belongs to the family Chlamydiaceae, with 11 identified species. The Chlamydia psittaci (C. psittaci) species is shared between animal hosts and humans. Ornamental birds are among the hosts of C. psittaci. This bacterium causes respiratory and gastrointestinal problems in these birds. This study aimed to determine the prevalence of chlamydial infection in ornamental birds in Urmia, Iran.
Methods: This descriptive study was conducted on 60 fecal swabs collected from 60 ornamental birds in Urmia. Giemsa staining and molecular polymerase chain reaction (PCR) testing, using genus-specific primers to amplify a 580-base pair (bp) fragment of the ompA gene, were performed on the samples.
Results: The Chlamydia molecule was detected in 11.7% of budgerigars with gastrointestinal symptoms and in 5.88% of apparently healthy budgerigars. Additionally, the infection was detected in 11.11% of cockatiels, 14.28% of mynahs, 20% of canaries, and 11.11% of finches, but not in other species.
Conclusion: The results of this study demonstrate the presence of the Chlamydia bacterium in ornamental birds in Urmia, which can be considered a source of infection for gastrointestinal diseases.
 

Background and Objective: Bariatric surgeries are among the most effective methods for treating obesity. A key postoperative challenge is insufficient weight loss or weight regain, which may be associated with eating disorders after surgery. This study was conducted to evaluate the prevalence of binge eating (BE) disorder following bariatric surgery in Gorgan, Iran.
Methods: This descriptive analytical study was performed on 133 patients (mean age = 42.65±9.78 years) who underwent bariatric surgery performed by a single surgeon for the treatment of obesity at Dr. Mousavi Hospital in Gorgan, Iran, during 2013-2019. Patients were invited for an interview, physical examination, and to complete a questionnaire via a phone call. After obtaining informed consent, participants' current height and weight were measured using a standard method, and the Binge Eating Disorder Scale (BEDS) was completed. Variables, such as the type of surgery and preoperative height and weight were extracted and recorded from patients' medical records. The prevalence of BE disorder was compared between patients with and without weight regain.
Results: Out of 133 participants, 44 (33.1%) experienced weight regain. Moderate or severe BE disorder was identified in 59 individuals (44.4%). The prevalence of BE disorder was significantly higher in patients with weight regain compared to those without (P<0.05). The odds of ratios (ORs) for weight regain were 3.7 and 3.9 times higher in individuals with moderate and severe BE disorder, respectively, compared to those without the disorder. No statistically significant association was observed between BE disorder and variables, such as gender, education, occupation, and marital status. However, among individuals who experienced weight regain, being a housewife had a statistically significant association with the disorder (P<0.05).
Conclusion: BE disorder is a significant factor in patient weight regain in the years following surgery, particularly among housewives.
