Primary bilateral macronodular adrenal hyperplasia: A rare case report of Cushing syndrome and review of literature
No full textRationale: Primary bilateral macronodular adrenal hyperplasia (PBMAH) is a rare cause of ACTH-independent Cushing syndrome (CS), accounting for <2% of CS cases. Diagnosing PBMAH can be difficult and challenging for clinicians. Patient concerns: We report a 52-year-old female, a patient with a history of intermittent fever for 3 years. She presented with nausea, headache, and dizziness for several days, along with fatigue, myalgia, muscle weakness, exertional dyspnea, hoarseness, spontaneous bruising over the past several months, and long-term psychological complaints. Additionally, we observed periorbital and facial edema, right lower quadrant tenderness, and abdominal striae during the examination. Diagnoses: Her laboratory results showed increased cortisol and suppressed ACTH, and an abdominal CT scan revealed 2 heterogeneous masses in the adrenal glands. These findings led us to the diagnosis of PBMAH in this patient. The existence of aberrant receptors was evaluated, and the tests were negative. Interventions: The patient underwent left adrenalectomy and corticosteroid therapy after the surgery. Her clinical complaints improved after the surgery. Outcomes: However, her dependency on corticosteroids was not transient after unilateral adrenalectomy, and she still needs glucocorticoid supplementation 1 year after surgery. Lessons: This patient is a case of PBMAH who presented with fever and CS symptoms and underwent unilateral adrenalectomy. Interestingly, she had suppressed cortisol levels for at least 1 year after the unilateral adrenalectomy. Therefore, we suggest further research on the most effective treatment strategies for PBMA
The importance of integrating flexible learning methods (audio‐visual animation vs. visual pamphlet) to enhance awareness, perspectives, and practices in preventing lower back pain in nurses. A quasi‐experimental study
No full textBackground and Aims: Nurses are highly susceptible to developing low back pain (LBP), which is considered a common occupational hazard. The present study investigated the efficacy of flexible learning methods on the nurses' awareness, perspectives, and practice regarding the prevention of LBP. Methods: In pre-test posttest quasi-experimental study conducted from June to December 2019, 153 eligible nurses working in three hospitals were participated. Researchers divided the hospitals into three groups with similar numbers of participants (around 55 each) using a random process. One group received an educational intervention using an audio-visual animation, another group got a visual pamphlet, and the last group served as a control with no intervention. All nurses completed a validated questionnaire designed by the researchers to assess their awareness, perspectives, and practices related to preventing lower back pain. The questionnaire was given three times: before the intervention, 1 week after, and 4 weeks after. Results: The study found that participants in the audio-visual and visual pamphlet groups scored significantly higher on awareness, perspective, and practice measures compared to the control group. Interestingly, the visual pamphlet group showed even greater awareness and practice scores compared to the audio-visual group (p < 0.001). However, the audio-visual group achieved a higher perspective score compared to the visual pamphlet group (p < 0.001). Conclusion: Nurses' perspective, awareness, and practice towards LBP prevention can be improved by blending the visual pamphlet and audio-visual animation
lncRNA HOTAIR and Cardiovascular diseases
No full textCardiovascular diseases (CVDs) a major contributor to global mortality rates, with a steadily rising prevalence observed across the world. Understanding the molecular mechanisms that underlie the signaling pathways implicated in the pathogenesis of CVDs represents a salient and advantageous avenue toward the development of precision and targeted therapeutics. A recent development in CVDs research is the discovery of long non-coding RNAs (lncRNAs), which are now understood to have crucial roles in the onset and development of several pathophysiological processes. The distinct expression patterns exhibited by lncRNAs in various CVDs contexts, present a significant opportunity for their utilization as both biomarkers and targets for therapeutic intervention. Among the various identified lncRNAs, HOX antisense intergenic RNA (HOTAIR) functions as signaling molecules that are significantly implicated in the pathogenesis of cardiovascular disorders in response to risk factors. HOTAIR has been observed to circulate within the bloodstream and possesses an integral epigenetic regulatory function in the transcriptional pathways of many diseases. Recent studies have suggested that HOTAIR offers promise as a biomarker for the detection and treatment of CVDs. The investigation on HOTAIR’s role in CVDs, however, is still in its early phases. The goal of the current study is to give a thorough overview of recent developments in the field of analyzing the molecular mechanism of HOTAIR in controlling the pathophysiological processes of CVDs as well as its possible therapeutic uses
Protective effects of rosmarinic acid against autistic-like behaviors in a mouse model of maternal separation stress: behavioral and molecular amendments
No full textAutism spectrum disorder (ASD) is a neurodevelopmental disorder with worldwide increasing incidence. Maternal separation (MS) stress at the beginning of life with its own neuroendocrine changes can provide the basis for development of ASD. Rosmarinic acid (RA) is a phenolic compound with a protective effect in neurodegenerative diseases. The aim of this study was to determine the effect of RA on autistic-like behaviors in maternally separated mice focusing on its possible effects on neuroimmune response and nitrite levels in the hippocampus. In this study, 40 mice were randomly divided into five groups of control (received normal saline (1 ml/kg)) and MS that were treated with normal saline (1 ml/kg) or doses of 1, 2, and 4 mg/kg RA, respectively, for 14 days. Three-chamber sociability, shuttle box, and marble burying tests were used to investigate autistic-like behaviors. Nitrite level and gene expression of inflammatory cytokines including TNF-α, IL-1β, TLR4, and iNOS were assessed in the hippocampus. The results showed that RA significantly increased the social preference and social novelty indexes, as well as attenuated impaired passive avoidance memory and the occurrence of repetitive and obsessive behaviors in the MS mice. RA reduced the nitrite level and gene expression of inflammatory cytokines in the hippocampus. RA, probably via attenuation of the nitrite level as well as of the neuroimmune response in the hippocampus, mitigated autistic-like behaviors in maternally separated mice
A rare association of pheochromocytoma, paraganglioma, and pituitary adenoma (3PA): A case report and literature review
No full textRationale: 3P association (3PA) is a rare condition with co-occurrence of pituitary adenoma and pheochromocytoma/paraganglioma. There have been less than a hundred documented cases of 3PA, which can be sporadic or related to genetic mutations. The present case report describes the first Iranian patient with 3PA and a 90th case of 3PA in the available literature. Patient concerns and interventions: A 36-year-old Caucasian male was admitted with headache and sudden increase in blood pressure. An abdominal CT scan revealed a retroperitoneal mass posterior to the inferior vena cava, later removed and diagnosed as a pheochromocytoma. Four years later, he noticed occasional mild headaches and a painless mass on the right side of his neck. The ultrasonography evaluations suggested a carotid body tumor, which was surgically removed. About a month after his second surgery, the severity of the patient's headaches worsened, and he developed right homonymous hemianopia. A brain MRI showed a mass in favor of macroadenoma, craniopharyngioma, or meningioma, and elevated prolactin level led to the diagnosis of macroprolactinoma. Diagnoses: Based on the provided history, this patient was diagnosed with 3PA, and a genetic study identified a positive succinate-dehydrogenase-complex subunit b mutation, possibly linked to his family history of carotid body tumor. Outcomes: He has remained symptom-free during his visits every 3 months. Lessons: The number of cases diagnosed with 3PA worldwide is increasing. Using clinical and genetic assessments, we can timely diagnose and adequately monitor individuals with or at risk of 3PA
Comments on “Negative effect of varicocele on sperm mitochondrial dysfunction: A cross-sectional study”
No full textEffective hands-on teaching strategy on participants’ confidence in medical writing and publishing: A before-after study
No full textProficiency in medical writing is crucial for disseminating reports of medical studies. The impact of workshops in this regard on participants’ confidence is a subject of debate. We assessed the impact of a hands-on workshop on participants’ confidence in medical writing. Participants of a 2-day “learning-by-doing” workshop held at McMaster University participated in this before-after study. We used a unique, reliable, and valid tool comprising two domains of confidence in medical writing and using English language before and after receiving the educational intervention. Of 25 participants, 21 completed the instrument before and after the workshop. Typical participants were female, and students in their 30s, who had not attended a prior workshop. The mean (95% CI) increase in the participants’ confidence for domain 1 was 15.3 (10.5, 20.1), for domain 2 was 16.8 (9.8, 23.8), and for the total score was 32.1 (20.9, 43.2) (all P<0.001). Between-subgroup analyses showed the score increase was significantly higher in participants with less than 5 years of experience in medical research. The workshop had a positive impact on enhancing participants’ confidence in writing skills, including using active verbs, crafting short sentences, summarizing main findings, and adhering to checklists like CONSORT. Hands-on medical writing workshops can boost participants’ confidence in writing medical articles and using optimal English language. Targeting junior researchers and graduate students could result in a better outcome. Emphasizing the writing areas where participants achieved higher score changes might yield better outcomes for such workshop
The Effect of Yoga and Pelvic Floor Muscle Exercise on Sexual Function and Sexual Self-esteem of Reproductive-age Women: A Randomized Clinical Trial
No full textBackground: Sexual function is a part of sexual health which is an important aspect of the quality of life. Physical activity is one of the healthiest activities that can effectively reduce the risk of sexual disorders. Therefore, this study was conducted with the aim of evaluating the effect of yoga and pelvic floor muscle exercises on the sexual function and sexual self-esteem of reproductive-age women. Methods: This randomized clinical trial study was conducted from September to December 2023 on 46 women of reproductive age working in the Shahrekord University of Medical Sciences and its affiliated health centers. Multi-stage cluster sampling was used to select the subjects; later, they were randomly divided into two intervention groups A (N=21) and B (N=25). Participants in intervention groups A and B performed pelvic floor muscle exercises at home using an educational pamphlet 3 times a week for 6 weeks, with 3 times a day repetition. In addition, women in the intervention group A participated in a yoga training program for 2 sessions per week for 6 weeks. Data collection tools included a demographic information form, the Female Sexual Function Index, and Sexual Self-Esteem Inventory for women. Questionnaires were completed by both groups before, immediately, and one month after the intervention. The data were analyzed using the chi-square test, fisher’s exact test, independent two-sample t-test, repeated measures test, and analysis of covariance in SPSS software version 16. A significance level of less than 0.05 was considered. Results: The results showed no statistically significant difference between the two groups in sexual function (P=0.21) and sexual self-esteem (P=0.22) scores before the intervention. Also, the results showed no statistically significant difference between the two groups in terms of sexual function (P=0.35) and sexual self-esteem (P=0.59) scores one month after the intervention. However, the mean score of the sexual function index immediately after intervention showed a statistically significant difference between the intervention groups A (31.43±3.76) and B (29.41±2.38) (P<0.001). The mean score of the sexual self-esteem immediately after the intervention showed a statistically significant difference between the intervention groups A (181.19±19.90) and B (171.32±15.02) (P<0.001). Conclusion: Adding yoga exercises to pelvic floor muscle exercises can improve the sexual function and sexual self-esteem of women at their reproductive age.

Evaluation of the effect of Nigella sativa oil on the outcome of missed abortion in women: A randomized double‐blind clinical trial
No full textBackground and Aim: Due to the concern about the side effects of chemical drugs and their ineffectiveness, the use of natural compounds as alternatives or complementary therapies has received increasing attention. The purpose of this study was to investigate the effect of Nigella sativa oil on the outcome of missed abortion. Methods: In this double-blind clinical trial, 70 nulliparous pregnant women referred to Hajar Hospital and Imam Ali clinics of Shahrekord and had missed abortion before the 12-week gestational age were selected and randomly divided into two interventions and control groups. The intervention group received 5 g of Nigella sativa oil alone daily for up to 3 days and the control group received a placebo. In case of nonresponse, 3 days after the last dose of medication or placebo, 800 μg of misoprostol (vaginal) were used. Data were analyzed by SPSS software. The chi-square test, Fisher's exact test, independent t-test and paired t-test were used for analytical statistics. Results: According to the results, 18 cases (51.4%) in the intervention group and seven cases (20%) in the control group showed complete evacuation of uterine contents which had a significant difference (p < 0.05). The frequency of vagina physical examination and type of hemorrhage did not show any significant difference between the two groups before and after the intervention. After the intervention, human chorionic gonadotropin (HCG) was significantly decreased in the intervention group but did not change in the control group (p < 0.05). The frequency of adverse events in the intervention group was three (8.6%) and in the control group was one (2.9%) which had no significant difference. Conclusion: Nigella sativa improves the outcome of missed abortion by reducing HCG and facilitating cervix dilatation and delivery of uterine contents
Legal and Ethical Recommendations for Video Recording in the Operating Room: A Review of Literature
No full textBackground: One of the legal and ethical issues related to the medical profession and health centers is patients’ uncertainty regarding the type and quality of clinical care provided and the extent to which the health care providers comply with the necessary criteria in delivering health care. This study investigated the civil, criminal, and ethical aspects of using cameras in the operating room by describing a case that a legal complaint had filed regarding this issue and a review of the literature. Methods: The study was a case report and narrative review. First, we introduce a case that found out that the patient admitted for brain tumor surgery did not operate on him and requested to review the videos of the operating room. Then, we investigated this issue in the literature. Results: The purpose and outcome of using Closed-Circuit Television (CCTV) in the Operating Room (OR), may vary depending on the goals, needs, and expectations of different stakeholders. Some countries may use CCTV in the OR primarily for educational, research, or quality improvement purposes. In contrast, others may use CCTV in the OR mainly for security, surveillance, or legal purposes. Conclusion: The suggestion of recording the events done in the operating room environment using a CCTV can be an acceptable solution and as a legal document and evidence
