Fulltext An observation on the decomposition process of gasoline-ingested monkey carcasses in a secondary forest in Malaysia

Rumiza AR, Khairul O, Zuha RM, Heo CC

Trop Biomed, 2010 Dec;27(3):373-83.
PMID: 21399577

This study was designed to mimic homicide or suicide cases using gasoline. Six adult long-tailed macaque (Macaca fascicularis), weighing between 2.5 to 4.0 kg, were equally divided into control and test groups. The control group was sacrificed by a lethal dose of phenobarbital intracardiac while test group was force fed with two doses of gasoline LD50 (37.7 ml/kg) after sedation with phenobarbital. All carcasses were then placed in a decomposition site to observe the decomposition and invasion process of cadaveric fauna on the carcasses. A total of five decomposition stages were recognized during this study. This study was performed during July 2007. Fresh stage of control and test carcasses occurred between 0 to 15 and 0 to 39 hours of exposure, respectively. The subsequent decomposition stages also exhibited the similar pattern whereby the decomposition process of control carcasses were faster than tested one. The first larvae were found on control carcasses after 9 hours of death while the test group carcasses had only their first blowfly eggs after 15 hours of exposure. Blow flies, Achoetandrus rufifacies and Chrysomya megacephala were the most dominant invader of both carcasses throughout the decaying process. Diptera collected from control carcasses comprised of scuttle fly, Megaselia scalaris and flesh fly, sarcophagid. We concluded that the presence of gasoline and its odor on the carcass had delayed the arrival of insect to the carcasses, thereby slowing down the decomposition process in the carcass by 6 hours.

Fulltext An occurrence of Synthesiomyia nudiseta (Wulp) (Diptera: Muscidae) from a human corpse in a high-rise building in Malaysia: a case report

Syamsa RA, Ahmad FM, Zuha RM, Khairul AZ, Marwi MA, Shahrom AW, et al.

Trop Biomed, 2012 Mar;29(1):107-12.
PMID: 22543610 MyJurnal

This is the first report of Synthesiomyia nudiseta (Wulp) (Diptera: Muscidae) on a human corpse discovered in a high-rise building in Malaysia. On 5 March 2008, a decomposing body of an adult female was found on the top floor of a thirteen-story building in Kuala Lumpur, Malaysia. Her body was colonized by S. nudiseta larvae, which were normally associated with corpses found indoors at ground level. The post-mortem interval (PMI) was estimated at approximately 5 to 9 days. This case is significant as it demonstrates that this species can locate a dead body even in a high-rise building. Further findings of fly distribution especially in high-rise buildings should be reported to assist entomologists in PMI analysis.

An unusual case of additional branches of median nerve innervating the corachobrachialis muscle and its clinical implications

Das S, Maatoq Sulaiman I, Hussan F, Haji Suhaimi F, Latiff AA, Othman F

Clin Ter, 2009;160(1):25-7.
PMID: 19290409

The flexor compartment muscles of the arm comprising of biceps brachii, brachialis and the coracobrachialis are innervated by the musculocutaneous nerve arising from the lateral cord of the brachial plexus. In the present study, we report a case of anomalous innervation of the corachobrachialis muscle on the left side of a 45-year-old male cadaver. The musculocutaneous nerve originated from the lateral cord, as usual and pierced the corachobrachialis muscle. The median nerve was formed by a contribution from both lateral and medial roots, both of which took origin from the lateral and medial cords, respectively. In addition to the usual musculocutaneous nerve which pierced the corachobrachialis muscle and innervated it, two more anomalous branches from the median nerve were observed to innervate the corachobrachialis. The anatomical knowledge of the variations of the innervations of the corachobrachialis muscle may be important not only for surgeons performing coracoid transfer but also for clinicians diagnosing nerve lesions.

Fulltext Angiographic anatomy of the extracranial and intracranial portions of the internal carotid arteries in donkeys

Khairuddin NH, Sullivan M, Pollock PJ

Ir Vet J, 2017 04 20;70:12.
PMID: 28439406 DOI: 10.1186/s13620-017-0090-0

BACKGROUND: In horses, the extracranial and intracranial pathway of the internal carotid artery has been described. The extracranial pathway of the internal carotid artery begins at the carotid termination and runs on the dorsal surface of the medial compartment of the guttural pouch. Thereafter the internal carotid artery passes through the foramen lacerum to continue intracranially, forming part of the rostrolateral quadrants of the cerebral arterial circle (Circle of Willis). The objectives of this study were to define and record the anatomy of the carotid arterial tree and the internal carotid artery in donkeys using angiographic techniques. This is a prospective descriptive study on 26 cadaveric donkeys.
METHODS: Twenty six donkey cadavers of mixed, age, sex and use presented for reasons unrelated to disease of the guttural pouch were subjected to carotid and cerebral angiography using rotational angiography. Rotational angiographic and 3 dimensional multiplanar reconstructive (3D-MPR) findings were verified with an arterial latex casting technique followed by dissection and photography.
RESULTS: The following variations of the carotid arterial tree were identified: [1] the internal carotid and occipital arteries shared a common trunk, [2] the linguofacial trunk originated from the common carotid artery causing the common carotid artery to terminate as four branches, [3] the external carotid artery was reduced in length before giving rise to the linguofacial trunk, mimicking the appearance of the common carotid artery terminating in four branches, [4] the internal carotid artery originated at a more caudal position from the common carotid artery termination.
CONCLUSION: Veterinarians should be aware that considerable variation exists in the carotid arterial tree of donkeys and that this variation may differ markedly from that described in the horse.

Angular stable lateral plating is a valid alternative to conventional plate fixation in the proximal phalanx. A biomechanical study

Shanmugam R, Ernst M, Stoffel K, Fischer MF, Wahl D, Richards RG, et al.

Clin Biomech (Bristol, Avon), 2015 Jun;30(5):405-10.
PMID: 25846324 DOI: 10.1016/j.clinbiomech.2015.03.019

Dorsal plating is commonly used in proximal phalanx fractures but it bears the risk of interfering with the extensor apparatus. In this study, dorsal and lateral plating fixation methods are compared to assess biomechanical differences using conventional 1.5mm non-locking plates and novel 1.3mm lateral locking plates.

Anomalous Course of Facial Artery Through the Submandibular Gland and its Redundant Loop at the Base of Mandible

Nayak SB, Vasudeva SK, Pamidi N, Sirasanagandla SR

J Craniofac Surg, 2020 Oct;31(7):2015-2016.
PMID: 32472879 DOI: 10.1097/SCS.0000000000006539

Knowledge of variant course and branching pattern of the facial artery gains importance in the surgeries of upper neck and face. The authors report a unilateral anomalous course and a redundant loop of right facial artery as seen in an adult male cadaver. The right facial artery had its origin from the external carotid artery. It pierced through the submandibular salivary gland and formed a redundant loop at the base of the mandible. Its further course and branching pattern was normal. This case could be important for radiologists, plastic surgeons and craniofacial surgeons.

Fulltext Anomalous peritoneal band connecting greater omentum to the ascending colon: a possible cause for dilation of ascending colon

Nayak SB, Soumya KV

Anat Cell Biol, 2020 Sep 30;53(3):372-375.
PMID: 32647076 DOI: 10.5115/acb.20.082

Anomalies of the peritoneum and the colon are quite common. Some of these anomalies can disturb the normal digestive and absorptive functions of the intestine and the others might result in formation of volvulus or impede the blood supply of the intestine. We report a rare, combined variation of peritoneum and ascending colon. In a 70-year-old male cadaver, the greater omentum was very small and extended only for about an inch below the transverse colon. From its lower end, a fibrous band extended to the right wall of the upper part of ascending colon. There was a deep constriction on the right wall of the ascending colon at the site of attachment of the fibrous band. The ascending colon was grossly dilated. Further, the ascending colon was mobile and presented a small ascending mesocolon along its left edge. We discuss the possible embryological basis and clinical and surgical relevance of the case.

Fulltext Ants (Hymenoptera: Formicidae) associated with pig carcasses in Malaysia

Heo CC, Mohamad AR, Rosli H, Nurul Ashikin A, Chen CD, John J, et al.

Trop Biomed, 2009 Apr;26(1):106-9.
PMID: 19696735

An observational study was conducted in an oil palm plantation in Tanjung Sepat, Selangor, Malaysia on August until September 2007 to note the decomposition process of pigs and their related faunal succession. We collected six species of ants (Formicidae) from 3 subfamilies: Formicinae (Oecophylla smaragdina and Anoplolepis gracilipes), Myrmicinae (Tetramorium sp. and Pheidologeton sp.) and Ponerinae (Odontoponera sp. and Diacamma sp.) that were associated with pig carcasses placed on the ground. Oecophylla smaragdina, Pheidologeton sp. and Tetramorium sp. were found on a partially burnt pig carcass whereas the other species were recovered from unburned pig carcass. These ants predated on fly eggs, larvae, pupae and adults. Ants could be found at all stages of decomposition starting from fresh until dry stage. Predatory ants can reduce fly population and thus may affect the rate of carcass decomposition but this was not seen in our study. Even though O. smaragdina was seen at all stages of decomposition of the burnt pig, this did not alter much the decomposition process by fly larvae.

Fulltext Are health professionals responsible for the shortage of organs from deceased donors in Malaysia?

Abidin ZL, Ming WT, Loch A, Hilmi I, Hautmann O

Transpl Int, 2013 Feb;26(2):187-94.
PMID: 23199156 DOI: 10.1111/tri.12019

The rate of organ donations from deceased donors in Malaysia is among the lowest in the world. This may be because of the passivity among health professionals in approaching families of potential donors. A questionnaire-based study was conducted amongst health professionals in two tertiary hospitals in Kuala Lumpur, Malaysia. Four hundred and sixty-two questionnaires were completed. 93.3% of health professionals acknowledged a need for organ transplantation in Malaysia. 47.8% were willing to donate their organs (with ethnic and religious differences). Factors which may be influencing the shortage of organs from deceased donors include: nonrecognition of brainstem death (38.5%), no knowledge on how to contact the Organ Transplant Coordinator (82.3%), and never approaching families of a potential donor (63.9%). There was a general attitude of passivity in approaching families of potential donors and activating transplant teams among many of the health professionals. A misunderstanding of brainstem death and its definition hinder identification of a potential donor. Continuing medical education and highlighting the role of the Organ Transplant Coordinator, as well as increasing awareness of the public through religion and the media were identified as essential in improving the rate of organ donations from deceased donors in Malaysia.

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.

Fulltext Bilateral Hydroureteronephrosis with a Hypertrophied, Trabeculated Urinary Bladder

Iqbal S, Raiz I, Faiz I

Malays J Med Sci, 2017 Mar;24(2):106-115.
PMID: 28894411 DOI: 10.21315/mjms2017.24.2.14

Bilateral hydroureteronephrosis involves the dilatation of the renal pelvis, calyces and ureter; it develops secondary to urinary tract obstruction and leads to a build-up of back pressure in the urinary tract, and it may lead to impairment of renal function and ultimately culminate in renal failure. Although clinically silent in most cases, it can be diagnosed as an incidental finding during evaluation of an unrelated cause. In a minority of patients, it presents with signs and symptoms. Renal calculus is the most common cause, but there are multiple non-calculus aetiologies, and they depend on age and sex. Pelviureteric junction obstruction, benign prostatic hypertrophy, urethral stricture, neurogenic bladder, retroperitoneal mass and bladder outlet obstruction are some of the frequent causes of hydroureteronephrosis in adults. The incidence of non-calculus hydronephrosis is more common in males than in females. Ultrasonography is the most important baseline investigation in the evaluation of patients with hydronephrosis. Here, we report a rarely seen case of bilateral hydroureteronephrosis associated with a hypertrophied, trabeculated bladder in an adult male cadaver, suspected to be due to a primary bladder neck obstruction, and analyse its various other causes, clinical presentations and outcomes.

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.

Cadaver wrapping and arrival performance of adult flies in an oil palm plantation in northern Peninsular Malaysia

Ahmad A, Ahmad AH, Dieng H, Satho T, Ahmad H, Aziz AT, et al.

J Med Entomol, 2011 Nov;48(6):1236-46.
PMID: 22238885

There is accumulating evidence that criminals wrap dead bodies in an attempt to conceal evidence. To anticipate the forensic implications of this phenomenon, we examined whether flies that are naturally associated with cadavers exhibit a delay in attendance or differ in species composition and abundance patterns because of the presence of wrapping material. Wrapped and exposed carcasses of dead monkeys placed in an oil plantation in Kedah, Malaysia, were visited over 50 d. On daily visits to each of the six carcasses, visiting adult flies were sampled using hand nets. Flies of 12 families were encountered. Calliphoridae (Chrysomya rufifacies Macquart and C. megacephala (F.) was the most prevalent family, followed by Sphaeroceridae. Some families tended to be more abundant in WRCs (i.e., Calliphoridae, Muscidae, and Phoridae), whereas others (i.e., Piophilidae, Sepsidae, and Psychodidae) were more prevalent in exposed carcasses. Wrapping delayed the arrival of all fly species encountered, with delays varying from 1 to 13 d depending on species. Wrapping did not affect species composition of flies, but prolong the occurrence of some species. The results of the current study emphasize the need to take into consideration the presence of a wrap when estimating postmortem interval.
