Association Between Foramen Rotundum and Trigeminal Neuralgia in the Saudi Population: A Radiological Study.

The trigeminal nerve is responsible for transmitting sensory information from the face, nasal and mouth cavities, and most of the scalp. Trigeminal neuralgia (TN) is a chronic facial pain disorder characterized by spontaneous paroxysmal pain throughout the distribution of the trigeminal nerve. This study investigated the morphological and morphometric variations of the foramen rotundum (FR) and its association with TN through a retrospective radiological analysis. A cohort of 97 participants from King Fahad University Hospital, Saudi Arabia, comprising 57 TN patients and 40 controls, underwent head CT scans for measurement and analysis. The study revealed significant differences in the FR morphology between TN patients and controls, particularly noting narrower FR measurements among TN individuals, especially in females. The right side demonstrated narrower FR dimensions, potentially correlating with the predominant side of pain in TN patients. While the presence of bony spurs was absent in all participants, variations in FR shape, size, and spatial positioning were observed and compared across genders and groups. These findings provide crucial insights into the potential anatomical factors contributing to TN, emphasizing the importance of understanding FR variations in clinical assessment and management of TN cases. Further research focusing on FR morphology and its clinical implications is recommended to enhance understanding and aid medical professionals in addressing TN-related concerns.

Morphometric Parameters of the Ear and Their Sexual Dimorphism in the Eastern Province of Saudi Arabia.

Background The human ear is a distinctive facial feature, revealing valuable information about ethnicity, gender, and age. Anthropometric measures play a crucial role in fields such as forensic medicine, prosthetics, and plastic surgery. The external ear, known for its diversity in structure and individual characteristics, has become a subject of interest in various populations. This study aims to determine the mean values of morphometric measurements for both right and left ears while exploring sexual dimorphism in ear dimensions. Methodology A prospective, observational, cross-sectional study was conducted among 200 volunteers from the eastern province of Saudi Arabia, comprising 98 males and 102 females, at the Department of Anatomy, Institute of Medical Sciences, Imam Abdulrahman Bin Faisal University. Participants were randomly selected from King Fahad University Hospital workers and patients. Using a Vernier caliper and after obtaining consent, various aspects of ear morphology were measured. The study employed statistical analyses such as the volunteers' t-test, Pearson's coefficient of correlation, and linear regression equations. Results In males, the mean total height of the right and left ears was 6.054 ± 0.5394 and 6.044 ± 0.5235 cm, respectively, while for females, it was 5.489 ± 0.4481 and 5.763 ± 4.8446 cm, respectively. The mean widths, heights, and other dimensions of the ears exhibited variations between genders. Conclusions The study provides comprehensive insights into the dimensions and indices of the pinna among the population of the eastern province of Saudi Arabia. The findings confirmed the presence of sexual dimorphism in the ear measurements, consistent with observations in other ethnic groups.

Morphometry of Conus Medullaris in the Saudi Population and Its Clinical Importance.

Objective The objective of this article is to evaluate the morphometry and termination of conus medullaris (CM) in the eastern province of Saudi Arabia. Methodology The lumbar spine magnetic resonance imaging (MRI) scans of 179 citizens of Saudi Arabia were selected and divided into males and females. Parameters such as the level of termination of CM, the length/width of CM, and its termination were reported. Results The maximum number of males and females were observed in the less than 20 years age group as 23 (25.5%) and 22 (24.7%), respectively. The termination level of CM was at the (first lumbar vertebra) L1 vertebra in 51.4% of the Saudi population. The level of termination of CM is below the (second lumbar vertebra) L2 level in one patient at L3, L3-L4, L5, and L5-S1 levels. On comparing the length of CM, no statistically significant difference was observed between the different levels of the vertebra. However, there was a statistically significant difference between the width and the CM termination (p=0.02). The various age groups and CM termination had no statistically significant correlation (p=0.47). Conclusion The most common level of termination of conus medullaris was at the L1 vertebra. The level of CM termination is strongly associated with the width of CM.

Comparative Study of Hypo-Fractionated Radiotherapy Versus Conventional Radiotherapy in Breast Cancer.

BACKGROUND: Breast cancer is the most commonly diagnosed cancer causing death among females worldwide. Radiotherapy after lumpectomy/mastectomy in breast cancer cases is a successful treatment modality taking five weeks to complete. The aim of the present study is to compare the effectiveness of hypo-fractionated radiotherapy in breast cancer patients with conventional radiotherapy with respect to outcome and toxicity. METHODS: Sixty patients were randomly divided equally into a conventional group, Group A (dose: 50 Gy in 25 fractions), and a hypo-fractionated short-course radiotherapy group, Group B (dose: 40 Gy in 16 fractions). After thorough clinical and laboratory examination of all patients, the disease status was assessed prior to radiotherapy and three and six months after completion of radiotherapy. The cardiopulmonary function was assessed using echocardiography and pulmonary function tests prior to the procedure. The assessment of the development of toxicity (dysphagia, skin, lung, and lymphedema) was done during every clinical visit. RESULTS: The mean age of patients was 53.28 ± 9.73 years in Group A, and 55.67 ± 10.41 years in Group B (p=0.82). The right breast was involved in 13 (43.4%) patients in Group A and 14 (46.6%) in Group B, and the left breast was involved n 17 (56.6%) patients in Group A and 16 (53.4%) in Group B (p=0.81). Most of the patients were post-menopausal; 24 (80%) in Group A and 25 (83.4%) in Group B (p=0.91). Eleven (36.6%) patients were of stage T2N1M0 in both groups. However, no statistical difference was observed between the groups in the TNM (tumor, node, and metastasis) staging using the AJCC (American Joint Committee on Cancer) criteria (p=0.26). On comparing the responses in Group A and Group B, no significant difference was observed in either of the groups from immediate post-treatment to the 12-month follow-up period (p=0.53 and p=0.64, respectively). CONCLUSION: Hypo-fractionated radiotherapy is as effective as conventional radiotherapy and can be used as an alternative method for treatment following breast cancer surgery.

A Comparative Study on Clinical Evaluation of the Hypolipidemic Effects of Allium sativum, Trigonella foenum-graecum, Commiphora mukul, Picrorhiza kurroa, and Piper nigrum: A Pilot Study.

Background Cardiovascular disease is a leading cause of morbidity and mortality. Therefore, it is essential to prevent cardiovascular diseases by correcting modifiable risk factors such as lowering lipid levels, lowering blood pressure, improving eating habits, giving up smoking, etc. The present study assessed the efficacy of herbal preparation containing Allium sativum (A. sativum), Commiphora mukul (C. mukul), and Trigonella foenum-graecum (T. foenum-graecum) in patients with hyperlipidemia. Methodology Patients were given extracts of A. sativum 350 mg, T. foenum-graecum 350 mg, C. mukul 200 mg, Picrorhiza kurroa (P. kurroa) 200 mg, and Piper nigrum (P. nigrum) 5 mg. Unichem Laboratories, Mumbai, provided placebo tablets similar in shape and size to herbal tablets. Patients were assessed for compliance, and a complete lipid profile was done at DO, D15, D46, D76, and D106. In addition, total cholesterol and high-density lipoprotein-cholesterol (HDL-C) serum triglyceride were estimated by the respective methods throughout the study. Results The weight of the patients remained stable, the mean weight before being 65.42 ± 8.35 kg and after completion of the study being 65.42 ± 8.35 kg. There were no changes in the ECG during or after the drug therapy in any of the patients. Group A comprised nine patients, and group B had ten patients. Serum creatinine (mg %) was 0.94 and 0.95, fasting blood sugar mg (%) was 111.05 and 99.63, and postprandial blood sugar (mg %) was 150.89 and 147.94 on pre-treatment and post-treatment, respectively. The mean serum triglyceride levels in group A were 271.11, 261.11, 293.89, 167.22, and 128.89, and serum HDL- C levels were 46.11, 46.11, 54.44, 52.22, and 54.44. Serum triglyceride levels in group B were 268, 268.5, 202, 171, and 116, and serum HDL- C levels were 48.5, 48, 50, 50, and 53.5 on day 0, 15, 46, 76, and 106, respectively. A significant reduction in total cholesterol levels was observed on D46, D76, and D106, with a maximum reduction on D76 (25.36%). Similarly, a reduction in serum triglyceride was also observed on D46, D76, and D106, with a maximum reduction on D106 (52.02%). A significant difference was observed (P <0.05). There was also a significant reduction of low-density lipoprotein cholesterol (LDL-C) on D46, D76, and D106, with the maximum reduction on D76 (28.79%). There was a significant rise of HDL-C on D46 and D106, with a maximum rise on D106 (15.41%). A significant difference was observed (P <0.05). Conclusion The study drugs are safe and efficacious in reducing the total cholesterol, serum triglycerides, LDL-C levels, and increasing HDL-C levels.

Defining the Components of the Deltoid Ligament (DL): A Cadaveric Study.

BACKGROUND: The deltoid ligament (DL) is a strong triangle-shaped ligament with a complex fascicular arrangement. Understanding the morphological and/or functional typing of the DL structure is hindered by a paucity of clear, quantitative, and reproducible data and is further complicated by inconsistent terminology use. The aim of this work was to describe different components of the DL using strict identification criteria. METHODS: Thirty embalmed cadaveric ankles of both sides were dissected on all sides and studied by using gross examination, micro-dissection, and light microscopy by tracing the fascicular pattern of each under 6X magnification. RESULTS: Six ligamentous bands were identified. The tibiotalocalcaneal ligament (TTC) and the superficial posterior tibiotalar ligament (sPTT) were two superficial variants and the anterior tibiotalar ligament (ATT), the anterior tibiotalonavicular ligament (ATTN), the intermediate tibiotalar ligament (ITT), and the deep posterior tibiotalar ligament (dPTT) were four deep variants. The TTC was identified in all 30 embalmed cadaveric specimens. Five additional ligamentous bands (ITT, sPTT, dPTT, ATT, and ATTN) were variable findings in the current cohort. CONCLUSION: This study presents six ligamentous bands as a regular finding and five additional ligamentous bands as variable findings in the dissected specimen. This data could assist in the radiological diagnosis of DL injuries and advanced procedures related to its surgical repair and reconstruction.
