    Bisep brachii (BB) adalah salah satu otot yang mempunyai pelbagai variasi.
    Terkini, kebanyakan maklumat adalah berkenaan variasi asal otot, namun terdapat
    beberapa kes yang melaporkan variasi dalam sisipan BB. Dibentangkan di sini
    kes BB otot yang mempunyai kedua-dua varian asal dan sisipan dalam otot yang
    sama. Varian asal BB adalah panjang dan besar di kepala ketiga (10.2 cm lebar
    dan 4.9 cm tebal) yang timbul dari pertengahan badan humerus. Lebih signifikan
    lagi, bahagian tengah kepala meliputi dan menyembunyikan bahagian bawah
    saraf median dan arteri brachial sebagai gerbang yang berterusan medially untuk
    disisipkan ke epicondyle medial humerus. Dalam laporan ini, kami membincangkan
    mekanisma yang mungkin untuk pemampatan neurovaskular oleh kepala ketiga
    otot BB yang tidak normal dan perubahan BB dari asal dan sisipan. Memahami
    perubahan ini adalah sangat penting dalam prosedur pembedahan di sekeliling
    sendi siku dan lengan atas dan ia juga memberi ruang untuk diagnosis pembezaan
    sindrom perangkap saraf

    Kenaikan segmen ST di elektrod aVR elektrokardiografi di dalam kes diseksi aorta mempunyai risiko kematian yang tinggi. Ia melibatkan diseksi yang berlaku di akar aorta. Kami melaporkan kes pesakit lelaki muda yang menghidap penyakit darah tinggi, yang datang ke Jabatan Kecemasan dengan sakit dada dan sakit di bahagian kaki. Pemeriksaan fizikal pada bahagian bawah kiri anggota adalah konsisten dengan iskemia akut. Elektrokardiogram menunjukkan serangan jantung akut di bahagian elektrod anterolateral, dan kenaikan ST segmen di elektrod aVR. Ekokardiografi menunjukkan akar aorta yang berukuran 4.51 cm dan kehadiran flap intimal, meningkatkan kebarangkalian diseksi pada akar aorta dan arteri koronari. Tomography Computed Angiogram menunjukkan terdapat diseksi aorta dari akar aorta termasuk flap intimal berhampiran permulaan arteri koronari kiri, hingga ke arteri iliac utama ke arteri iliac kiri. Malangnya, pesakit memilih untuk tidak menjalani pembedahan dan akhirnya meninggal dunia selepas 48 jam di masukkan ke wad. Kes ini menjelaskan bahawa, dalam kes diseksi aorta yang hadir dengan sindrom 'malperfusion', kenaikan segmen ST pada elektrod aVR akan meningkatkan kebarangkalian terjadinya diseksi aorta yang teruk melibatkan akar aorta dan juga arteri koronari, yang menjadikan prognosis pesakit lebih teruk.

    Posterior interosseus artery flap is commonly used as a pedicle flap to cover soft tissue defect in the dorsum of the hand. It is not able to cover a soft tissue defect beyond the level of proximal phalang unless it is used as a free flap. We illustrate 2 cases in which large soft tissue defect in the finger was able to close by using a contralateral posterior interosseous flap. This technique is a reliable alternative method for closing large soft tissue defect in the fingers.

    Facial artery is known to show variations in its origin, course, termination, and branching pattern. One of its reported variant branch is called premasseteric branch. During our dissection classes, it was observed that an elderly male cadaver had 3 premasseteic branches arising from the facial artery. The first and second premasseteric branches passed deep to masseter under its anterior border, whereas the third premasseteric branch terminated by anastomosing with the infraorbital artery. This case could be of importance to maxillofacial surgeons, craniofacial surgeons, and plastic surgeons.

    Umbilical artery catheterisation is considered the standard of care for arterial access in neonatal intensive care unit. It is routinely used for blood sampling and blood pressure monitoring. Unfortunately, an indwelling umbilical catheter have been associated with thrombotic complication which may result in either partial or complete occlusion of the aorta. We report here our experience in the diagnosis and treatment of a neonate with this condition.

    The study of blood flow in obstructed arteries is a significant focus in computational fluid dynamics, particularly in the field of biomedicine. The primary objective of this research is to investigate the impact of pulsating blood velocity on heat transfer within biological systems, with a specific focus on blood flow in obstructed arteries. To achieve this goal, a comprehensive 3D model representing a straight, constricted blood vessel has been developed. This model incorporates periodic, unsteady, Newtonian blood flow along with the presence of gold and silver nanoparticles. Leveraging the Finite Element Method (FEM), the Navier-Stokes and energy equations have been rigorously solved. Through the investigation, it is aim to shed light on how alterations in the pulsation rate and the volume fraction of nanoparticles influence both temperature distribution and velocity profiles within the system. The present study findings unequivocally highlight that the behavior of pulsatile nanofluid flow significantly impacts the velocity field and heat transfer performance. However, it is imperative to note that the extent of this influence varies depending on the specific volume fractions involved. Specifically, higher volume fractions of nanofluids correlate with elevated velocities at the center of the vessel and decreased velocities near the vessel walls. This pattern also extends to the temperature distribution and heat flux within the vessel, further underscoring the paramount importance of pulsatile flow dynamics in biomedicine and computational fluid dynamics research. Besides, results revealed that the presence of occlusion significantly affects the heat transfer and fluid flow.

    Not long ago, hearables paved the way for biosensing, fitness, and healthcare monitoring. Smart earbuds today are not only producing sound but also monitoring vital signs. Reliable determination of cardiovascular and pulmonary system information can explore the use of hearables for physiological monitoring. Recent research shows that photoplethysmography (PPG) signals not only contain details on oxygen saturation level (SPO2) but also carry more physiological information including pulse rate, respiration rate, blood pressure, and arterial-related information. The analysis of the PPG signal from the ear has proven to be reliable and accurate in the research setting. (1) Background: The present integrative review explores the existing literature on an in-ear PPG signal and its application. This review aims to identify the current technology and usage of in-ear PPG and existing evidence on in-ear PPG in physiological monitoring. This review also analyzes in-ear (PPG) measurement configuration and principle, waveform characteristics, processing technology, and feature extraction characteristics. (2) Methods: We performed a comprehensive search to discover relevant in-ear PPG articles published until December 2022. The following electronic databases: Institute of Electrical and Electronics Engineers (IEEE), ScienceDirect, Scopus, Web of Science, and PubMed were utilized to conduct the studies addressing the evidence of in-ear PPG in physiological monitoring. (3) Results: Fourteen studies were identified but nine studies were finalized. Eight studies were on different principles and configurations of hearable PPG, and eight studies were on processing technology and feature extraction and its evidence in in-ear physiological monitoring. We also highlighted the limitations and challenges of using in-ear PPG in physiological monitoring. (4) Conclusions: The available evidence has revealed the future of in-ear PPG in physiological monitoring. We have also analyzed the potential limitation and challenges that in-ear PPG will face in processing the signal.

    Hemobilia is a rare but potentially lethal condition. The commonest cause of hemobilia is trauma, accounting up to 85% of all cases. Hemobilia caused by gallstones is very rare. Most of the cases of hemobilia are either managed conservatively or treated by embolization. Surgery is indicated only when there is an associated surgical condition or when embolization fails. We report a case of a 72-year-old patient with massive hemobilia caused by gallstone erosion to the adjacent artery, diagnosed intraoperatively. The complication was successfully managed by cholecystectomy and repair of the bleeding vessel. This case highlights the importance that hemobilia should be suspected in patients presenting with upper gastrointestinal bleeding. Although rare, massive hemobilia can be life threatening, leading to significant morbidity and mortality. Therefore, a high index of suspicion and timely intervention are important.

    The unsteady blood flow in the stenosed porous artery subjected to a magnetic field was studied analytically. Oscillating
    pressure gradient and periodic body acceleration were imposed on the flow field. The effects of the magnetic field and
    the permeability of the stenosed artery on the blood velocity were studied. The results showed that the magnetic field
    affected the flow field significantly which can be beneficial for some practical problems.

    The present work was carried out to investigate the blood flow behavior and the severity of blockage caused in the
    arterial passage due to the different geometries such as elliptical, trapezium and triangular shapes of stenosis. The study
    was conducted with respect to various sizes of stenosis in terms of 70%, 80% and 90% area blockage of the arterial
    blood flow. The study was carried out numerically with the help of advance computational fluid dynamic software. It
    was found that the shape of the stenosis plays an important role in overall pressure drop across the blockage region
    of artery. The highest level of pressure drop was observed for trapezoidal shape of stenosis followed by elliptical and
    then by triangular shaped stenosis. The wall shear stress across the stenosis is great for trapezoidal shape followed by
    triangular and elliptical stenosis for same blockage area in the artery.

    Medical Doppler ultrasound is usually utilized in the clinical adjusting to evaluate and estimate blood flow in both the major (large) and the minor (tiny) vessels of the body. The normal and abnormal sign waveforms can be shown by spectral Doppler technique. The sign waveform is individual to each vessel. Thus, it is significant for the operator and the clinicians to understand the normal and abnormal diagnostic in a spectral Doppler show. The aim of this review is to explain the physical principles behind the medical Doppler ultrasound, also, to use some of the mathematical formulas utilized in the medical Doppler ultrasound examination. Furthermore, we discussed the color and spectral flow model of Doppler ultrasound. Finally, we explained spectral Doppler sign waveforms to show both the normal and abnormal signs waveforms that are individual to the common carotid artery, because these signs are important for both the radiologist and sonographer to perceive both the normal and abnormal in a spectral Doppler show.

    Vascular complications are important causes of cerebral infarction in tuberculous meningitis (TBM).Transcranial Doppler ultrasonography (TCD) is a non-invasive tool that can provide real-time information about cerebral hemodynamics. However, the literature on the role of TCD in the diagnosis or monitoring of vasculopathy associated with TBM is scarce. We explored the role of TCD in the diagnosis and monitoring of TBM-related vasculopathy of the major intracranial arteries.

    PURPOSE: Rete middle cerebral artery (MCA) anomaly is characterized by a web-like network of arteries involving the first MCA segment (M1) and a normal downstream MCA. The detailed composition of this anomaly and the hemodynamic impacts on cerebral perfusion are rarely addressed. The purpose of this study was to elucidate the anatomical and hemodynamic perspectives of the rete MCA anomaly.

    METHODS: From August 2020 to December 2021, 4 rete MCA anomalies were identified at Shuang Ho hospital. Clinical information, perfusion magnetic resonance (MR) imaging, and angiographic images were collected. Detailed angioarchitecture, including types of arterial feeders and extent of rete involvement, were analyzed based on three-dimensional volume-rendering reconstruction images obtained from the catheter-based angiographies.

    RESULTS: Despite their variable clinical presentations (two hemorrhage, one ischemia, and one asymptomatic), all cases shared common angiographic findings as follows: (1) the internal carotid artery did not connect directly to the rete, (2) the anterior choroidal artery (AChA) was the artery constantly supplying the rete and (3) there was a watershed zone shift toward MCA territory. The perfusion MR cerebral blood flow map was symmetric in all studied cases.

    CONCLUSION: The AChA is an artery constantly supplying the rete, which suggests that the angioarchitectural features associated with this anomaly may be the result of both congenital and acquired compensatory processes. Cerebral perfusion remains preserved at the lesion side, despite angiographic evidence of watershed zone shift. These findings will be important for making better clinical judgments about this condition.
