    PMID: 17143371
    The knowledge of vascular variations like other anatomical variations, is important during the operative, diagnostic, and endovascular procedures in abdomen. This report describes multiple variations in the upper abdominal vessels as found during the routine dissection in a 60-year-old male cadaver. The variations found were; presence of a celiaco-mesenterico-phrenic trunk, a common inferior phrenic trunk, 2 right renal arteries originating from abdominal aorta, 2 suprarenal arteries originating from the lower right renal artery, 3 right renal veins opening separately into inferior vena cava, and termination of right testicular vein into the lowest vein among the 3 right renal veins. The existence of a celiaco-mesenterico-phrenic trunk has not been reported yet. Although, other variations reported in this case exist as individual variations, a concomitant variation of them has not been reported yet. The knowledge of such variations is quite useful in planning any upper abdominal surgery.

  2. Variant origin of an arterial trunk from axillary artery continuing as profunda brachii artery--a unique arterial variation in the axilla and its clinical implications
    Naveen K, Jyothsna P, Nayak SB, Mohandas RK, Swamy RS, Deepthinath R, et al.
    Ethiop J Health Sci, 2014 Jan;24(1):93-6.
    PMID: 24591805
    BACKGROUND: Axillary artery is known to show different variations mostly in its branching pattern. Similarly, the origin of profunda brachii is often encountered with abnormality. Therefore, when the vascular variations in the upper limb persist, mostly it is confined to its branching pattern followed by its variant origin. But, among all the reported variations of profunda brachii, its variant origin from the 3rd part of the axillary artery with common trunk for the branches of axillary artery is unique.

    CASE DETAILS: We report here an anomalous origin of profunda brachii as continuation of an arterial trunk arising from 3rd part of the axillary artery. This common trunk at its commencement passed between 2 roots of median nerve and gave branches of 3rd part of axillary artery before it continued as profunda brachii artery. The further course and branching pattern of profunda brachii were normal.

    CONCLUSION: Since the axillary artery is next choice of artery for arterial cannulation in cardiopulmonary bypass procedures, prior knowledge of existence of such variation in its branching pattern helps in avoiding possible diagnostic or interventional therapeutic errors.

    Introduction: Degenerative disorder involving the acromioclavicular
    joint (ACJ) is quite common especially in the elderly.
    One of the surgical modalities of treatment of this disorder is the
    Mumford Procedure. Arthroscopic approach is preferred due to
    its reduced morbidity and faster post-operative recovery. One
    method utilizes the anteromedial and Neviaser portals, which
    allow direct and better visualization of the ACJ from the
    subacromial space. However, the dangers that may arise from
    incision and insertion of instruments through these portals are
    not fully understood. This cadaveric study was carried out to
    investigate the dangers that can arise from utilization of these
    portals and which structures are at risk during this procedure.
    Methods: Arthroscopic Mumford procedures were performed
    on 5 cadaver shoulders by a single surgeon utilizing the
    anteromedial and Neviaser portals. After marking each portals
    with methylene blue, dissection of nearby structures were
    carried out immediately after each procedure was completed.
    Important structures (subclavian artery as well as brachial plexus
    and its branches) were identified and the nearest measurements
    were made from each portal edges to these structures. Results:
    The anteromedial portal was noted to be closest to the
    suprascapular nerve (SSN) at 2.91 cm, while the Neviaser portal
    was noted to be closest also to the SSN at 1.60 cm. The
    suprascapular nerve was the structure most at risk during the
    Mumford procedure. The anteromedial portal was noted to be
    the most risky portal to utilize compared to the Neviaser portal.
    Conclusion: Extra precaution needs to be given to the
    anteromedial portal while performing an arthroscopic distal
    clavicle resection in view of the risk of injuring the
    suprascapular nerve of the affected limb.

  4. Permeation Studies of Captopril Transdermal Films Through Human Cadaver Skin
    Nair RS, Nair S
    Curr Drug Deliv, 2015;12(5):517-23.
    PMID: 25675336
    Mortality rate due to heart diseases increases dramatically with age. Captopril is an angiotensin converting enzyme inhibitor (ACE) used effectively for the management of hypertension. Due to short elimination half-life of captopril the oral dose is very high. Captopril is prone to oxidation and it has been reported that the oxidation rate of captopril in skin tissues is considerably low when compared to intestinal tissues. All these factors make captopril an ideal drug candidate for transdermal delivery. In this research work an effort was made to formulate transdermal films of captopril by utilizing polyvinylpyrrolidone (PVP) and polyvinyl alcohol (PVA) as film formers and polyethylene glycol 400 (PEG400) as a plasticizer. Dimethyl sulfoxide (DMSO) and dimethylformamide (DMF) were used as permeation enhancers. Physicochemical parameters of the films such as appearance, thickness, weight variation and drug content were evaluated. The invitro permeation studies were carried out through excised human cadaver skin using Franz diffusion cells. The in-vitro permeation studies demonstrated that the film (P4) having the polymer ratio (PVP:PVA = 80:20) with DMSO (10%) resulted a promising drug release of 79.58% at 24 hours with a flux of 70.0 µg/cm(2)/hr. No signs of erythema or oedema were observed on the rabbit skin as a result of skin irritation study by Draize test. Based on the stability report it was confirmed that the films were physically and chemically stable, hence the prepared films are very well suited for transdermal application.

  7. Absence of the Musculocutaneous Nerve and Associated Compensation by the Median Nerve
    Moore K, Prasad AM, Satheesha Nayak B
    Kathmandu Univ Med J (KUMJ), 2021 6 24;18(71):313-315.
    PMID: 34158443
    The musculocutaneous and median nerves frequently show variations from their normal course. The purpose of this paper is to report a rare variation, in which the right musculocutaneous nerve was absent. Consequently, the median nerve supplied motor innervation to the flexor compartment of the arm and sensory innervation to the lateral aspect of the forearm. The primary targets of this paper are orthopedic surgeons, anesthesiologists and radiologists. In cases of injuries to the upper limb, knowledge of these variations can assist them in avoiding misdiagnoses.

  8. Variant course of posterior circumflex humeral artery associated with the abnormal origin of radial collateral artery: could it mimic the quadrangular space syndrome?
    Mohandas Rao KG, Somayaji SN, Ashwini LS, Ravindra S, Abhinitha P, Rao A, et al.
    Acta Med Iran, 2012;50(8):572-6.
    PMID: 23109033
    Variations in the origin of axillary artery branches are common. But, distinctly abnormal course of its posterior circumflex humeral branch is rare. We are reporting a case of posterior circumflex humeral artery (PCHA) originating from the axillary artery, passing through lower triangular space to reach the scapular region where it accompanied the axillary nerve and posterior circumflex humeral vein to pass around surgical neck of humerus, deep to the fibers of deltoid. Other variations observed in this specimen were the radial collateral artery arising from the PCHA, middle collateral artery arising directly from the brachial artery and absence of profunda brachii artery. PCHA forming a hair pin loop, traversing through lower triangular space instead of quadrangular space taking a long course is being reported for the first time. Further, the clinical and surgical importance of this case especially in relation with quadrangular space syndrome and relevant literature is discussed.

  10. Fulltext Iliotibial band tension reduces patellar lateral stability
    Merican AM, Iranpour F, Amis AA
    J Orthop Res, 2009 Mar;27(3):335-9.
    PMID: 18925647 DOI: 10.1002/jor.20756
    This study investigated the effect of loading the iliotibial band (ITB) on the stability of the patellofemoral joint. We measured the restraining force required to displace the patella 10 mm medially and laterally (defined as medial and lateral stability, respectively) in 14 fresh-frozen knees from 0 to 90 degrees knee flexion. The testing rig allowed the patella to rotate and translate freely during this displacement. The quadriceps was separated into five components and loaded with 175 N total tension. Testing was performed at 0 to 90 N ITB tension. With no ITB tension, the lateral restraining force ranged from 82 to 101 N across 0 to 90 degrees flexion. Increasing ITB tension caused progressive reduction of the lateral restraining force. The maximum reduction was 25% at 60 degrees flexion and 90 N ITB tension. Medial restraining force increased progressively with increasing knee flexion and increasing ITB loads; it ranged from 74 N at 0 degrees knee flexion and 0 N ITB tension to 211 N at 90 degrees knee flexion and 90 N ITB tension. The maximum effect was an increase of medial restraining force of 50% at 90 degrees flexion and 90 N ITB tension.

    The type and amount of resources available significantly influences the structure and dynamics of food webs. In this study, we analyzed differences in species richness of scavengers based on carcass type in Riyadh, Saudi Arabia. We collected insects from experimental carcasses of three different types, domestic dogs (Canidae, Canis lupus familiaris), Hijazi goats (Bovidae, Capra aegagrus hircus), and camels (Camelidae, Camelus dromedarius). Data collection was conducted during the decay stage in June, 2016. We used mitochondrial cytochrome c oxidase subunit I (mtCOI) barcodes as a marker for the molecular identification of the scavenger insects. The results showed that there were more insects on the camels and goats than the dogs. In total, seven species were found on all carrions. Six species were found on the camels and goats, but only five were found on the dog. Musca domestica was the most collected species of flies whereas, Necrobia rufipes was the most collected species of beetles. Overall, this study showed that carrion type had an effect on the type and number of insects attracted to the carrions. Thus, one of the significant factors that influence the associated scavenger assemblage is a carcass type.

    MyJurnal
    Palmaris longus is tendon of choice in reconstructive, plastic and cosmetic surgeries. Thus, a suitable length is required and it would be more convenient if the length of the tendon of the palmaris longus could be estimated before harvesting. This study was carried out to determine the relationship between the length and width of the palmaris longus tendon and the length of forearm and hand, the relationship between the length and the width of the palmaris longus tendon and wrist width and wrist circumference, as well as to identify a technique to estimate the length of the tendinous part of palmaris longus before harvesting it. A standardized proforma was used to collect the data of each of the 31 cadavers upper limbs. These data were analysed using SPSS software version 17. It is important to note that p value less than 0.05 is considered as statistically significant in this study. Out of the 31 upper limbs, palmaris longus tendon was absent in 3 (9.68%). Meanwhile, the mean length and width of the palmaris longus tendon was found to be 16.20 cm and 0.48 cm, respectively. The mean length of the forearm and hand was 26.6 cm and 21.2 cm, respectively. The mean width of the wrist and wrist circumference was 8.2 cm and 14.82 cm, respectively. These indicate a significant and moderate relationship between the length of palmaris longus tendon and the length of forearm (r = 0.49, r2 = 0.24, p < 0.01). In addition, there was also a significant relationship between the length of palmaris longus tendon and the length of hand (r = 0.56, p < 0.01). This paper presents the technique used to estimate the length and width of the tendinous part of palmaris longus before harvesting. The length of palmaris longus can be estimated pre-operatively by measuring the length of the hand by using the technique explained in this paper.

    Introduction: Anatomy continues to be an important basic subject in medicine and other related health sciences which is delivered by method of either through lectures or demonstration. Thus, having a gross anatomy practi- cal with cadaver is a crucial phase for the students to have a deep understanding about anatomy of human body. The objective of this study is to explore the attitude and perception of medical and health science students in the importance of cadaver dissection in learning anatomy. Methods: A cross-sectional study was conducted by distrib- uting closed structured questionnaires to 270 respondents consisting of socio-demographic in part one, frequency on practical with dissected cadaver in part two, the attitude of student towards the dissected cadaver in part three, suggestion for improvement during practical with cadaver in part four and the value of cadavers during practical in part five. The collected data were processed by using Statistical Package for Social Sciences (SPSS) version 23.0. Result: Descriptive statistical evaluation shows majority of the students perform practical with cadavers. They find cadaveric dissection exciting with no feeling of stress and anxiety. Many of them never had an emotional shock when exposing themselves to the cadavers for the first time accepting the cadaveric dissection ethically. The students recommended keeping cadaveric dissection in the health science curriculum. Conclusion: The cadaveric dissection helps in grounded understanding of anatomy. It promotes and develops psychomotor skills in students. The findings of the study discovered dissection to be a motivating tool in learning anatomy.

    Considering that crimes against animals such as illegal killing and cruelty have been alarmingly increasing and since burning is one of the common ways for disposing cadavers, ability to estimate minimum postmortem interval (PMI) using entomological data merits consideration. Chrysomya megacephala and Chrysomya rufifacies are common necrophagous species recovered from cadavers in many countries including Malaysia. Specific studies focusing on the oviposition and developmental patterns of both species on cadavers manifesting different levels of burn as described by the Crow-Glassman Scale (CGS) remain scarce. In four replicates, rabbit carcasses were burned to CGS levels #1, #2 and #3 by varying the amount of petrol used and duration of burning. Oviposition by C. megacephala and C. rufifacies was delayed by one day in the case of carcasses burned to the CGS level #3 (p<0.05) when compared with that of controls. Such delay in oviposition was not observed in the CGS level #1 and #2 carcasses. No significant differences (p>0.05) in the duration of development were found between control and burned carcasses. These findings deserve consideration while estimating minimum PMI since burning as a mean for disposing animal and human cadavers is gaining popularity.

  17. Fulltext Malathion extraction from larvae of Chrysomya megacephala (Fabricius) (Diptera: Calliphoridae) for determining death due to malathion

    Trop Biomed, 2012 Mar;29(1):9-17.
    PMID: 22543598 MyJurnal
    The use of Chrysomya megacephala larvae for detecting malathion for diagnosing the cause of death was investigated. This could prove useful when the visceral organs have become liquefied during decomposition and therefore cannot be sampled. A field experiment was conducted in which C. megacephala were allowed to colonise naturally the corpses of rabbits that had died of malathion poisoning. The concentration of malathion increased gradually during the larval stages of C. megacephala reaching the maximum concentration in the third instar larvae. The concentration of malathion declined during prepupal stage and reached its lowest level among tenerals. The average malathion concentrations in C. megacephala growing in poisoned rabbit corpses left in a sunlit habitat were significantly higher (p<0.05) than those growing on poisoned rabbits left in a shaded habitat. The concentrations of malathion in the different stages of development of C. megacephala were moderately correlated (r = 0.51-0.69) with the administered doses as well as with those estimated in visceral organs. Thus, it would not be reliable to suggest the formulation of mathematical algorithms for relating the concentration of malathion found in the different stages of development of C. megacephala with those found in the visceral organs. However, in the context of forensic investigation, the qualitative detection of malathion in C. megacephala may prove useful in diagnosing the cause of death, since malathion is a common cause of accidental and suicidal deaths.

    PMID: 24096921 DOI: 10.1097/SIH.0b013e3182a86165
    Arthroscopy uses a completely different skill set compared with open orthopedic surgery. Hitherto, arthroscopy had not been given enough emphasis in the core orthopedic curricula. Simulation has been seen as an excellent way to teach the skills required in arthroscopy. The simulators used for arthroscopy training can be broadly classified into physical simulators such as cadavers, animals, models and box trainers, virtual-reality simulators, and hybrid simulators that combine virtual-reality simulation with physical components that allow real tactile feedback. The advantages and disadvantages of each of these types have been described in this article. The factors that determine skill acquisition using these simulators have been highlighted. In conclusion, simulation seems to be a valuable tool for arthroscopy training, although further studies are needed to state whether this translates into better operative skill on real patients.

    Radial tunnel syndrome refers to pain on the lateral aspect of the forearm as a result of compression of the posterior interosseous nerve within a tunnel with specific anatomical boundaries. Diagnosis of the condition is difficult because of its close association with lateral epicondylitis, which warrants different methods of treatment. Based on a cadaveric study, a new clinical test, the Rule-of-Nine test, is proposed to improve the diagnostic accuracy in radial tunnel syndrome. The test involves constructing 9 equal squares on the anterior aspect of the forearm and noting those squares where tenderness can be elicited.
