A human corpse at an advanced stage of decomposition was found in a house in the residential area of Bukit Mertajam, Penang, Malaysia. Entomological specimens were collected during the post-mortem and the live specimens were subsequently reared at room temperature. The time of death was estimated to have been 14 days previous to the discovery of the body based on the police investigation. Both adult and larvae of the beetle Dermestes ater (De Geer) were found to be infesting the corpse and from the stage of decomposition of the body and the estimated time of death it would appear that infestation may have begun at a relatively early stage of decomposition.

PMID: 19901906 MyJurnal

Larvae of the Synthesiomyia nudiseta (Wulp) were collected from a decomposed human corpse at the Department of Forensic Medicine, Penang Hospital. A colony of this species was established and the eggs were collected for rearing. The developmental times, rearing temperatures, and relative humidity were recorded twice daily from the time the eggs collected until adult emergence. An average of 5 larvae were randomly collected from the rearings twice daily, warm-water killed and preserved in Kahle's solution. The larval instar stages were determined by observing the number of posterior spiracular slits and the length of the preserved larvae were measured. When the larval life cycle was completed, the accumulated developmental times were calculated. A total of 8 replicates were carried out. The temperature of the rearing room was 28.5+/-1.5 degrees Celcius while the relative humidity was within 67-85%. The total developmental time for S. nudiseta was 322+/-19 hours (13.4+/-0.8 days).

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.

Comparison between percutaneous fluoroscopic-guided and conventional open pedicle screw placement techniques for the thoracic spine: a safety evaluation in human cadavers

Kwan MK, Chiu CK, Lee CK, Chan CY

Bone Joint J, 2015 Nov;97-B(11):1555-61.

PMID: 26530660 DOI: 10.1302/0301-620X.97B11.35789

Percutaneous placement of pedicle screws is a well-established technique, however, no studies have compared percutaneous and open placement of screws in the thoracic spine. The aim of this cadaveric study was to compare the accuracy and safety of these techniques at the thoracic spinal level. A total of 288 screws were inserted in 16 (eight cadavers, 144 screws in percutaneous and eight cadavers, 144 screws in open). Pedicle perforations and fractures were documented subsequent to wide laminectomy followed by skeletalisation of the vertebrae. The perforations were classified as grade 0: no perforation, grade 1: < 2 mm perforation, grade 2: 2 mm to 4 mm perforation and grade 3: > 4 mm perforation. In the percutaneous group, the perforation rate was 11.1% with 15 (10.4%) grade 1 and one (0.7%) grade 2 perforations. In the open group, the perforation rate was 8.3% (12 screws) and all were grade 1. This difference was not significant (p = 0.45). There were 19 (13.2%) pedicle fractures in the percutaneous group and 21 (14.6%) in the open group (p = 0.73). In summary, the safety of percutaneous fluoroscopy-guided pedicle screw placement in the thoracic spine between T4 and T12 is similar to that of the conventional open technique.

Fulltext The health care professional's attitudes towards brain death and cadaveric organ transplantation: the influence of cadaveric donor and transplantation programs--a Malaysian survey

Rozaidi SW, Sukro J, Dan A

Med J Malaysia, 2000 Dec;55(4):478-85.

PMID: 11221161

One of the main reasons for poor response in organ donation is the lack of positive attitudes and knowledge present in health care professionals. Definite legislation, policies and programmes dealing with brain death and cadaveric organ transplantation have shown some favourable results in terms of increasing donor rates. These programmes are mainly Western based; therefore adopting such programmes to be used locally may not be adequate or proper. To address this issue, we decided to carry out a questionnaire in two tertiary hospitals in Malaysia, one with a well establish brain death and cadaveric organ transplantation programme and one with none.

PMID: 24770815 DOI: 10.7471/CT.2014.1687

During extensive osteological study of 150 dry skulls in the Department of Anatomy, Vardhman Mahavir Medical college, an unusual Paramedian Occipital (POC) condyle was detected in the occipital bone of a cadaveric skull. The anatomical details of this unusual occipital condyle were carefully studied and its morphometric measurements taken. A coronal multiplanner reformatted image and a volume rendered image were taken to study radiological details and establish significant clinical correlation. Precise understanding of anatomy of craniovertebral junction and its anomalies have become immensely important for the present day surgeon during orthopaedic and neurosurgical procedures of this region . Technical advancements in imaging modalities such as CT and MRI scans further signify the importance of these anatomical variations ,which are often missed in routine examination. Osteological study combined with radiological details of the paramedian occipital condyle in the present case aims to emphasize the importance of bony anomalies in the craniovertebral region and their role in diagnosis and appropriate treatment of neurovascular compression syndromes of craniovertebral junction. The present study highlights anatomical details, clinical relevance and embryological basis of such a rare unusual paramedian occipital condyle.

Clin Ter, 2012 Nov;163(6):503-4.

PMID: 23306746

The right and left lobes of the thyroid gland are connected by an isthmus. The isthmus lies at the level of the second and third tracheal rings. Occasionaly, the isthmus may be absent. We hereby, report the absence of isthmus in a 52-year-old male cadaver of unknown origin. Both the right and left lobes were normal but they were separated. Both the right and left lobes of the thyroid gland measured 4.3 cm vertically. The separation distance between right and left glands was noted at the upper, middle and lower parts. The upper end of medial border of both lobes were separated by a distance of 1 cm while the separation distance was 0.7 cm and 1.5 cm at the middle and lower parts, respectively. The anatomical and clinical significance of absence of isthmus is important for medical personnel and the surgeons operating on the thyroid gland. The present case report is a an attempt to highlight such.

Clin Ter, 2015;166(2):65-7.

PMID: 25945432 DOI: 10.7417/CT.2015.1817

Variations in the arterial pattern of upper limb are of colossal importance to the surgeons as they are liable to iatrogenic injuries. During routine dissection for undergraduate medical students, an anomaly of brachial artery was discovered. The brachial artery terminated at higher level into ulnar and radial artery. The common interosseus artery took origin arising from radial artery. The ulnar artery did not give any branches in the forearm. Both radial and ulnar artery displayed a superficial course in the forearm. The anatomical knowledge of these variations may be of great help for the clinicians in planning and conducting flap harvesting during reconstructive surgeries and in arteriography.

PMID: 34882828 DOI: 10.1111/ahe.12771

This study was conducted to describe the morphometrics of nuchal ligament and investigate the effects of different neck and body positions on the nuchal ligament in greyhounds. Nine adult greyhounds cadavers without any locomotion abnormalities were dissected through the neck musculature on the left side to expose the nuchal ligament. Three pins were placed to mark regions of interest on the nuchal ligament: at one cm cranial to the site of origin (the most dorsal point of the spinous process of the first thoracic vertebra), at the midpoint of the nuchal ligament and one cm caudal to the nuchal ligament site of insertion (close to the caudal aspect of the spinous process of the axis). Each cadaver was positioned on a masonite board and placed on a table on the floor in their lateral recumbency and seven different standardized body positions; P1-P7 were mimicked using goniometers and metal wires. Photographs were taken by positioning and fixing the camera above the nuchal ligament region. The length and widths (W1, W2 and W3) of nuchal ligament were measured using Image Pro software (Image-Pro Express version 5.0) on standardized photographs of each of seven different body and neck positions. The length of nuchal ligament in relation to the neutral position (P1) was less (- 7%, p > 0·05) in P6 (neck elevated) and increased in all other positions (+1%, p > 0·05 for P2, +19%, p 0·05 for P5, +40%, p

Morphometric analysis and surgical adequacy of palmaris longus as a tendon graft. A systematic review of cadaveric studies

Yammine K, Erić M

Surg Radiol Anat, 2020 Mar;42(3):259-267.

PMID: 31741040 DOI: 10.1007/s00276-019-02381-x

INTRODUCTION: The tendon of the palmaris longus is commonly used as a tendon graft in many reconstructive surgeries. Easy to access and at proximity to the hand, the palmaris longus tendon is considered as the optimal tendon source for hand reconstructive surgery. However, and besides its inconsistency, the size of the palmaris longus tendon is reported to show variability. The aim of this study is to look for the surgical adequacy of the palmaris longus tendon by conducting a quantitative synthesis on its length and width in human populations and its correlation with the forearm length.

METHODS: Twenty-four studies met the inclusion criteria including 1761 cadaveric limbs.

RESULTS: The results were as following: (a) the mean palmaris longus tendon length was of 13.9 ± 2.6 cm, (b) the mean ratio palmaris longus tendon length/forearm length was of 0.545 ± 0.06, (c) the weighted correlation value was of 0.686, and (d) the mean palmaris longus tendon width was of 4.0 ± 1.7 mm. Only five studies reported a palmaris longus tendon length of more than 15 cm. The palmaris longus tendon length was shown to vary between ancestries; the Japanese had the shortest while Malaysian the longest palmaris longus tendons. All studies but one reported a palmaris longus tendon mean width of more than 3 mm where the minimal mean palmaris longus tendon width was of 2.5 mm.

CONCLUSION: While the requested length depends on the recipient site and/or type of reconstructive surgery, the palmaris longus tendon often met the required diameter for grafting. Our review demonstrated that while palmaris longus length varies between ancestries, its width is often adequate for grafting. In addition, the forearm length could be a good predictor of palmaris longus tendon length; such correlation could assist surgeons when planning to use palmaris longus tendon as a graft source.

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.

An atavastic belly of the flexor digitorum profundus with absence of tendon of flexor digitorum superficialis to the little finger: morphological and histological considerations

Das S, Norzana AG, Azian AL, Farihah HS, Faizah O

Clin Ter, 2011;162(6):555-7.

PMID: 22262329

In this case report, we report the absence of the fourth tendon of flexor digitorium superficialis (FDS) to the little finger with a concurrent anomalous muscular belly of flexor digitorum profundus (FDP) in the palm. The FDS originated from the medial epicondyle, divided into three tendons for the index, middle and ring fingers with the little finger devoid of any attachment. The FDP exhibited a muscular belly which passed deep to the flexor retinaculum (FR) and continued for another 4 cm thereby dividing into four slips for the index, middle, ring and little fingers. The presence of the muscular belly of the FDP lead us to think whether it was an adhesion between the tendons of the FDP, so we proceeded to histological analysis. The tissue was processed and stained with Hematoxylin and Eosin. Abundant longitudinal muscle fibers with peripherally situated nuclei confirmed it to be a skeletal muscle. Absence of the tendon of FDS to little finger may influence the flexion movement in the middle and proximal interphalangeal joints. Presence of anomalous muscle belly of FDP in the palm may mimic any soft tissue tumour, compress neurovascular structures or even pose difficulty while performing tendon transplant surgeries.

PMID: 33597485

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.
