An anomalous muscle in the distal half of the arm

Dharap AS

Surg Radiol Anat, 1994;16(1):97-9.
PMID: 8047976

During dissection an anomalous muscle was found on the medial aspect in the distal half of one left upper extremity. This muscle arose from the humerus between the m. coracobrachialis and the m. brachialis, passed obliquely across the front of the brachial artery and median nerve and blended with the common origin of the forearm flexor muscles. It does not appear to be an additional head of the biceps brachii or the brachialis muscles. The existence of this anomalous muscle should be kept in mind in a patient presenting with a high median nerve palsy together with symptoms of brachial artery compression.

Age at death estimation from bone histology in Malaysian males

Nor FM, Pastor RF, Schutkowski H

Med Sci Law, 2014 Oct;54(4):203-8.
PMID: 24189643 DOI: 10.1177/0025802413506573

Estimation of age from microscopic examination of human bone utilizes bone remodeling. This allows 2 regression equation to be determined in a specific population based on the variation in osteon turnover in different populations. The aim of this study was to provide age estimation for Malaysian males. Ground undecalcified cross sections were prepared from long limb bones of 50 deceased males aged between 21 and 78 years. Ten microstructural parameters were measured and subjected to multivariate regression analysis. Results showed that osteon count had the highest correlation with age (R = 0.43), and age was estimated to be within 10.94 years of the true value in 98% of males. Cross validation of the equation on 50 individuals showed close correspondence of true ages with estimated ages. Further studies are needed to validate and expand these results.

Fulltext Accidents and injuries related to powered paragliding: a cross-sectional study

Feletti F, Goin J

BMJ Open, 2014 Aug 28;4(8):e005508.
PMID: 25168039 DOI: 10.1136/bmjopen-2014-005508

OBJECTIVES: Powered paragliding (PPG) and paragliding are two totally different sports, mainly because of the use of an engine in powered paragliding. As a consequence, the pattern of injuries caused by each of these two sports may be different.
SETTING: To test this hypothesis, we analysed 384 incident reports gathered by the US Powered Paragliding Association from 1995 to 2012. The majority of the incidents occurred in the USA, while 26 incidents occurred elsewhere: Canada (8), Mexico (5), Panama (1), China (1), Japan (1), Malaysia (1), Indonesia (Java) (1), Europe (8): of which Spain (1), Belgium (1), UK (3), Italy (1), Romania (1), unknown (1).
OUTCOME: To identify the most affected body area and the most common type of injury sustained in PPG, and to highlight any differences from paragliding.
RESULTS: The most affected body areas in PPG were the upper limbs (44.5%), followed by the lower limbs (32%), the back (9.8%), the head (7%), the pelvis (3.1), the chest (2.7%) and the abdomen (0.7%) (p<0.001). The engine caused 43 accidents (11.2%) in our study and was responsible for the majority of injuries to the upper limbs. The number of fatal accidents in PPG is not lower than in paragliding and hang-gliding.
CONCLUSIONS: To help prevent the specific injuries of PPG, the most appropriate equipment should be identified. The results of this study also suggest that, in the future, this sport should be analysed separately from paragliding.

The computer is well known as one of the important tools in the office that gives a lot of benefits but silently leads to musculoskeletal pain. There are many different kinds of musculoskeletal complaints pain but the most common seen among computer users in developed countries is the complaint of arm, neck and shoulder (CANS). Despite this, definite factors that can be associated with the prevalence of CANS have not been established. This study was conducted to identify the prevalence and factors associated with work-related complaints of arm, neck and shoulder (CANS) among office workers in Selangor and Kuala Lumpur. A survey study design was conducted where 110 (n=110) office workers were recruited from around the Selangor and Kuala Lumpur area for 5 months periods. Participants were required to answer the Maastricht Upper Extremity Questionnaire (MUEQ) and the Level of Ergonomic Knowledge Questionnaire. The study showed the highest percentage of CANS reported was at neck region (53.6% of participants), followed by shoulders with 53.0%. The majority of participants have low level of computer ergonomic awareness where only 19.09% (n=21) from government sector and 10% (n=11) office workers from private sector reported knowledge of ergonomics. Majority of the participants did not have the know-how in implementing correct computer ergonomics. However there was a weak association (r=

PMID: 21594085 DOI: 10.3897/zookeys.89.761

Simulium (Nevermannia) maeaiensesp. n. is described on the basis of female, male, pupal and larval specimens collected from Chiang Mai Province, Thailand. This species is assigned to the feuerborni species-group of the subgenus Simulium (Nevermannia), and is distinctive among this species-group in having the female cibarium furnished with numerous dark minute conical processes on the lower part, the female genital fork with a strongly sclerotized horizontal bar on each arm, and six long pupal gill filaments arising nearly at the same level from the common basal stalk and lying in a horizontal plane. Identification keys to seven species of the feuerborni species-group reported from Thailand are provided for females, males, pupae and mature larvae.

This study aimed to explore the clinical characteristics of hand arm vibration syndrome (HAVS) in a group of tree fellers in a tropical environment. We examined all tree fellers and selected control subjects in a logging camp of central Sarawak for vibration exposure and presence of HAVS symptoms utilizing vibrotactile perception threshold test (VPT) and cold water provocation test (CWP). None of the subjects reported white finger. The tree fellers reported significantly higher prevalence of finger coldness as compared to the control subjects (OR=10.32, 95%CI=1.21-87.94). A lower finger skin temperature, longer fingernail capillary return time and higher VPT were observed among the tree fellers as compared to the control subjects in all fingers (effect size >0.5). The VPT following CWP of the tree fellers was significantly higher (repeated measures ANOVA p=0.002, partial η(2)=0.196) than the control subject. The A (8) level was associated with finger tingling, numbness and dullness (effect size=0.983) and finger coldness (effect size=0.524) among the tree fellers. Finger coldness and finger tingling, numbness and dullness are important symptoms for HAVS in tropical environment that may indicate vascular and neurological damage due to hand-transmitted vibration exposure.

PMID: 24162147

OBJECTIVES: The aim of this study was to investigate the clinical characteristics of HAVS in a tropical environment in comparison with a temperate environment.
METHODS: We conducted a series medical examinations among the forestry, construction and automobile industry workers in Malaysia adopting the compulsory medical examination procedure used by Wakayama Medical University for Japanese vibratory tools workers. We matched the duration of vibration exposure and compared our results against the Japanese workers. We also compared the results of the Malaysian tree fellers against a group of symptomatic Japanese tree fellers diagnosed with HAVS.
RESULTS: Malaysian subjects reported a similar prevalence of finger tingling, numbness and dullness (Malaysian=25.0%, Japanese=21.5%, p=0.444) but had a lower finger skin temperature (FST) and higher vibrotactile perception threshold (VPT) values as compared with the Japanese workers. No white finger was reported in Malaysian subjects. The FST and VPT of the Malaysian tree fellers were at least as bad as the Japanese tree fellers despite a shorter duration (mean difference=20.12 years, 95%CI=14.50, 25.40) of vibration exposure.
CONCLUSIONS: Although the vascular disorder does not manifest clinically in the tropical environment, the severity of HAVS can be as bad as in the temperate environment with predominantly neurological disorder. Hence, it is essential to formulate national legislation for the control of the occupational vibration exposure.

Malays Fam Physician, 2019;14(2):44-45.
PMID: 31827738

Elbow injuries are common in children. Supracondylar fractures occurred in 16% of all pediatric fractures. Supracondylar fractures can be classified into 4 types according to the Gartland classification, depending on the degree of the fracture present in the lateral radiograph. This case highlights the case of a child with a Gartland Type I fracture. A misdiagnosis of this fracture will compromise the management of the injury with regards to immobilization and subsequent care. As this injury can be managed on an outpatient basis, primary care frontliners need to be aware of the condition.
