RESUMO

Objective@#To examine the usefulness and feasibility of modified thread carpal tunnel release (TCTR) by comparing the results of using pre-existing commercial thread with those of a newly developed thread (Smartwire-01). @*Methods@#A total of 17 cadaveric wrists were used in the study. The modified TCTR method was practiced by two different experts. Pre-existing commercial surgical dissecting thread (Loop&ShearTM) was used for five wrists and the newly developed Smartwire-01 was used for twelve wrists. The gross and microanatomy of the specimens were evaluated by a blinded anatomist. @*Results@#Both types of thread were able to cut the TCL similarly. Gross anatomy and histologic findings showed that there was no significant difference between the two types of threads. However, the practitioners felt that it was easier to cut the TCL using the newly-developed thread. @*Conclusion@#TCTR using Smartwire-01 was as effective as pre-existing Loop&ShearTM, with better user experiences.

RESUMO

Objective@#: The percutaneous thread transection technique is a surgical dissecting method using a dissecting thread inserted through a needle under ultrasound guidance without skin incision. As the new dissecting threads were developed domestically, this cadaver study was conducted to compare the effectiveness and safety between the new threads (ultra V sswire and smartwire-01) and a pre-existing commercial dissecting thread (loop & shear) by demonstrating a modified looped thread cubital tunnel release. @*Methods@#: The percutaneous cubital tunnel release procedure was performed on 29 fresh cadaveric upper extremities. The preexisting commercial thread was used in 5 upper extremities. The two newly developed threads were used in 24 upper extremities. Two practitioners performed the procedures separately. After the modified looped thread cubital release, anatomical and histological analyses were performed by a blinded anatomist. The presence of the dissected cubital tunnel and damaged adjacent soft tissue was assessed. @*Results@#: Out of the 29 cadaveric upper extremities, 27 specimens showed complete dissection of the Osborne ligament and the proximal fascia of the flexor carpi ulnaris muscle. One specimen was incompletely dissected in each of the ultra V sswire and smartwire-01 groups. There were no injuries of adjacent structures including the ulnar nerve, ulnar artery, medial antebrachial cutaneous nerve, or flexor tendon with either the commercial thread or the newly developed threads. The anatomical analysis revealed clear and sharp incisional margins of the cubital tunnel in the Smartwire-01 and loop & shear groups. All three kinds of threads maintained proper linear elasticity for easy handling during the procedure. The smartwire-01 provided higher visibility in ultrasound than the other threads. @*Conclusion@#: The newly developed threads were effective and safe for use in the thread cubital tunnel release procedure.

RESUMO

The gluteal region is a frequent target for injecting high volumes. However, the safe intramuscular injection sites have been controversy in this region. This study was aimed to compare the subcutaneous fat and muscle thicknesses at the two gluteal injection sites and to determine the influence of sex and body mass index (BMI) on fat and muscle thicknesses.The ultimate purpose of this study is to suggest the most suitable intramuscular injection site among the ventrogluteal and dorsogluteal regions. Eleven fresh cadavers were injected with colored gelatin using syringes at the two gluteal injection sites.Seven variables were measured at both gluteal injection sites and analyzed relative to sex and the BMI. No variables showed statistically significant differences between the two gluteal injection sites according to sex. In a one-way analysis of variance, total length and muscle thickness had significant difference according to the BMI category. In obese cadavers, the injected gelatin core was located in the subcutaneous layer (average 109.0 percentile), and in the muscle layer (average 78.9 percentile) in the dorsogluteal region. These were found that the success rate of injection in the dorsogluteal region was higher than in the ventrogluteal region, especially when classed as obese. Also, it is suggested that nurses should use the traditional intramuscular injection method. It will also be necessary to consider expanding these findings to other ethnic groups in the Asia–Pacific region and then also education in universities and health providers on selecting the intramuscular gluteal injection site.

RESUMO

Understanding anatomic variations in neurovascular structure inside the femoral triangle is crucial for regional anesthesiologists performing femoral nerve block. During routine dissection of a cadaver, an ascending branch of the lateral circumflex femoral artery with an anomalous course passing through the femoral nerve, specifically the posterior division, was identified inside the femoral triangle on the left thigh. The novel variation identified in this study occurred in an early stage of prenatal development. Recognition of this anatomic variation will be helpful for reducing unexpected complications during the femoral nerve block and the tensor fascia latae flap. Penetration of the posterior division of the femoral nerve by the arterial branch might cause pain or paresthesia of the medial aspect of the leg in the distribution of the saphenous nerve.

RESUMO

For treatment of the rotator cuff, locating the structure and position of the rotator cuff is crucial. The aim of this study is to identify the size of each rotator cuff and the locational relationship with bony landmarks, and to provide superficial landmarks for locating the tendon from the surface. Fifty-two shoulders from 26 cadavers were dissected and measured in a supine position. The central point was set as the most protrusive point on the greater tubercle of the humerus. The measurement of angles was described ventral as positive (+) and dorsal as negative (-) placing the long axis of the humeral shaft at 0degrees. The range of the angle which each rotator cuff tendon is attached to the humerus head was: 53.8~103.3 degrees for the subscapularis, -17.1~25.7 degrees for the supraspinatus, -68.4~-1.9 degrees for the infraspinatus, and -117.1~-75.7 degrees for the teres minor. The vertical inferior point drawn from the anterior edge of the acromion to the humerus was 7.5+/-11.7 degrees from the central point. The average position of the point was the midpoint of insertion of the supraspinatus tendon. The lateral horizontal point drawn from the acromial angle to the humerus was -49.4+/-14.3 degrees away and located at an average of 30% inferior to the infraspinatus tendon. Also the lateral horizontal point drawn from the most protrusive point of the coracoid process to the humerus was 63.1+/-14.7 degrees away and located at an average of 20% superior to the subscapularis tendon. Lastly, the most protrusive point of the lesser tubercle of the humerus was located at a range of 80.8+/-11.1 degrees and an average of 60% superior to the insertion of the subscapularis tendon. For the measurements of the size of the rotator cuff, there was no statistical difference between the left and right. However, the four measurements - the proximal width of the teres minor tendon, the proximal and distal width, and the length of the subscapularis tendon - showed statistically significant difference between the sexes (P<0.05). Therefore, to identify the location of the tendon structures by palpation for shoulder treatment, using the lesser tubercle for the subscapularis, the anterior edge of the acromion for the supraspinatus, and the acromial angle for the infraspinatus as landmarks is regarded to be effective.

RESUMO

This study was undertaken to investigate mineral changes in weathered scalp hair after burial. EDX (energy dispersive X-ray spectroscopy) analysis was performed to measure the presence of minerals on the hair surface. Twelve scalp hairs, buried for 5-40 years, were chosen from deceased individuals buried in tombs in Soha-Ri, Kyonggi-Do, and other regions in Korea. Three normal hairs were used as the control group. EDX data showed that carbon, oxygen, and sulfur were detected in hair collected from all three burial grounds. In contrast, calcium was only detected in hair collected from tombs in Soha-ri. The amounts of calcium and sulfur were found to decrease with time for hair collected from tombs in Soha-ri. Similar results were observed with sodium for hair collected from other regions. These results show region specific mineral detection and a decrease in the concentration of minerals with time. Consequently, it is suggested that changes in minerals concentration in weathered hair could be used as basic data in the field of forensic medicine.

RESUMO

Modiolus is convergence of the facial muscles at the angle of the mouth, and its shape and size varying with individual, age, sex and ethnicity. In the previous study, the modiolus was usually located under the horizontal line at the mouth angle. In most medical schools, the cadavers are of later ages and their facial muscles have lost their elasticity as they got older. The purpose of this study is to identify the location of the modiolus in live young Korean and to compare it with that of Korean cadavers from the previous study. Participants were one hundred students of the catholic medical school with a mean age of 24 years. Experimenter palpated the modiolus of each student with thumb and index finger. The average young live Korean modiolus was located at 14.4 mm lateral to mouth angle and 1.6 mm below the horizontal line of the mouth angle. Commonly, it is located below the mouth angle in 124 sides (62%). There was difference between horizontal distance of female and of male, and vertical distance of right and of left. The location of the modiouls was symmetric in 67%. These results were consistent with the previous study using Korean cadavers. Therefore these results suggest that the location of the modiolus is below to the mouth angle in large number of Koreans.

RESUMO

This study was undertaken to investigate the morphological changes of scalp hair according to weathering after burial and to offer basic data for forensic science. To examine the effect of weathering degree, the 51 human scalp hairs buried after death were taken from deceased individuals in tombs in Korea. The morphological changes in weathering hair shafts of the scalp were investigated using the transmission electron microscopes (TEM). There were little morphological differences of weathering depending on the burial period. The weathering changes includes detachment of cuticle layer, aggregation of macrofibril and hollow formation in the cortex according to the burial period. These results could provide basic data to the field of forensic medicine.

RESUMO

We studied the distribution patterns of perforating branch of superficial circumflex iliac artery for flap surgery in Korean. Fifty one thighs from 34 Korean cadavers (17 males/ 17 females) were dissected and standard points were determined as follows: point of anterior superior iliac spine (A), point of pubic tubercle (B), cross point of the line AB and femoral artery (FA), cross point of the femoral artery and the sartorius muscle (FAS), beginning point of superficial circumflex iliac artery (O), and perforating point of superficial circumflex iliac artery (P). We measured the distance and the angles between the standard points. Each frequency of superficial circumflex iliac artery from femoral artery and superficial epigastric artery is 69.6% and 30.4% respectively. The mean distance between the beginning point of superficial circumflex iliac artery (O) and the point A was 7.3+/-1.3 cm and the mean distance between the point O and the point B was 5.7+/-0.6 cm. The angle from line OA to line AB was 17.9+/-8.0 degrees and The angle from line OB to the line AB was 24.9+/-5.1 degrees. The mean distance between the perforating point for superficial circumflex iliac artery (P) and the point A was 6.3+/-2.4 cm and the mean distance between the point P and the point B was 8.3+/-2.7 cm. The angle from line PA to line AB was 33.4+/-18.3 degrees and the angle from line PB to the line AB was 24.5+/-14.3 degrees. Consequently, the pattern of distribution of superficial circumflex iliac arteries, obtained in this study, will provide useful anatomical backgrounds for the superficial circumflex iliac artery flap surgery in Korean.

RESUMO

The present study was designed to observe the expression patterns of NF-kappa B and AP-1, redox-sensitive transcription factors, and Bcl-2 and Bax, apoptosis repressing and promoting factors, respectively, upon repetitive cycles of short ischemia and reperfusion. Nine and thirty five weeks old Sprague-Dawley rats were subjected to the 3, 6, and 10 cycles of the ischemic process for 5 minutes followed by reperfusion for 5 minutes. The rats were divided by 5 groups, according to the time after treatment, such as 0, 3, 6, 24 and 72 hours. For short ischemia and reperfusion, left common iliac artery was occluded 3, 6, and 10 times for 5 minutes of ischemia followed by 5 minutes of reperfusion using rodent vascular clamps and left rectus femoris muscles were removed. The expression profiles and distribution of NF-kappa B, AP-1, Bcl-2, and Bax which were observed using immunohistochemical staining methods with 6 microgram thick paraffin sections of the rectus femoris tissue were as follows: The distribution of NF-kappa B was increased as the cycles of ischemia and reperfusion increased up to 3 hours after treatment. This phenomenon was prominent in 35 weeks-old rats. The distribution of AP-1 was increased as the cycles of ischemia and reperfusion increased up to 3 hours after treatment. This phenomenon was prominent in 9 weeks-old rats. The distribution of Bcl-2 was decreased as the cycles of ischemia and reperfusion increased up to 3 hours after treatment. The extent of such reduction was more prominent in 35 weeks-old rats than 9 weeks-old rats. The distribution of Bax was increased as the cycles of ischemia and reperfusion increased up to 3 hours after treatment. After 3 hours of treatment, Bax positivity was gradually decreased in 9 weeks-old rats, but increased in 35 weeks-old rats to reach a peak at 24 hour after reperfusion. The extent of enhancement in 9 weeks-old rats was higher than that in 35 weeks-old rats. In summary, multiple episodes of short ischemia and reperfusion altered the expression profiles of NF-kappa B, AP-1, Bcl-2, and Bax in the rectus femoris muscle at the similar extents in 9 and 35 weeks-old rats. Such alterations were more more increased when the episodes were more repeated.

RESUMO

Rheumatoid arthritis (RA), which is frequently involved in the articulations of the hands and feet, is known to be related with inheritance. Dermatoglyphics, the patterns of ridges on the skin of the fingertips, palms, and soles, are mostly related with inheritance. The purpose of this study is to verify the possibility that dermatoglyphics are helpful for the diagnosis of RA. We attempted to compare the characteristics of the fingerprints, palmprints, and palm creases in 67 Korean RA patients (RA group) to those in 3, 216 normal Korean persons. In the RA group, the radial loop and whorl were more frequent whereas the arch and ulnar loop were less frequent. The total fingerprint ridges were more numerous and 11 palmprint D type was more frequent in the RA group. Also, the Simian and Sydney creases were more frequent and the total degree of palm crease transversality was lower in the RA group. In addition, a part of the dermatoglyphic characteristics of the Korean RA group were different from those of the Indian RA group. These results suggest that dermatoglyphics may be helpful in the diagnosis of Korean RA patients.

RESUMO

This study was performed to measure the distance of perforating point for superficial and deep external pudendal arteries from pubic tubercle and anterior superior iliac spine, patterns of arterial distribution, and external diameter. Fifty three thighs from 27 Korean cadavers (13 males / 14 females), clinically normal and without deformity, were dissected and standard points were determined as follows: point of pubic tubercle (A) and point of anterior superior iliac spine (B). The obtained results were as follows: 1. The external pudendal artery branched from femoral artery was distributed in the medial thigh. Superficial external pudendal artery is located above the saphenous opening and Deep external pudendal artery is located below the saphenous opening. 2. The saphenous opening were 4.7+/-1.2 cm apart from point A and 10.1+/-1.3 cm from B. 3. The superficial external pudendal artery were 5.2+/-1.2 cm apart from A and 8.9+/-2.1 cm from B. 4. The deep external pudendal artery were 4.7+/-1.1 cm apart from A and 10.8+/-1.3 cm from B. Consequently, the patterns of distribution of superficial and deep external pudendal arteries, obtained in this study, will provide useful anatomical backgrounds for the external pudendal flap surgery in korean.

RESUMO

The pattern of location, perforator artery and skin territory of the descending branch of the lateral circumflex femoral artery are very important to the anterolateral thigh free flap surgery. The author studied the pattern of vascularization of the anterolateral thigh in 110 Korean cadavers using macroscopic dissection and radiographic methods. The location of the points in this study were expressed as XY coordination in reference to the line between ASIS and center of the lateral margin of the patella. The location of pedicle of the vastus lateralis muscle at XY coordination valued X: 20.8+/-6.0 cm, Y: -1.2+/-1.0 cm. The length and external diameter of the pedicle were 91.7+/-54.9 mm, and 2.7+/-0.8 mm respectively. The average number of perforator artery to the vastus lateralis muscle were 3.2+/-1.5. The skin territory of the perforator of the vastus lateralis muscle was 6 x 18 cm2, its location was 20.8 cm on the line AB. The pattern of distribution and territories of the anterolateral thigh obtained in this study will provide useful anatomical backgrounds for the flap surgery of anterior and anterolateral thigh.

RESUMO

Gracilis muscle, the most superficial to the adductor groups of muscles in the thigh, is widely used to make musculo-cutaneous flap because this muscle has several advantages; 1) Removal of the muscle does not elicit any functional deficit, 2) It is easy to make a flap, 3) It is able to make flaps of various sizes in according to the size of the wound. This study demonstrates the characteristics of the arterial supply of the gracilis muscle for flap. Total 102 thighs from 51 Korean cadavers (32 males/ 19 females), clinically normal and without deformity, were dissected and length and width of gracilis muscles were measured. The pattern of distribution of the arteries supplying the muscle were studied, and entering point of each arteries to the muscle were located in according to following point; A: Pubic tubercle, B: Medial condyle of femur and tibia on gracilis muscle. 1. The average width of gracilis muscle were 31.9 +/-8.1 mm. The length of female subjects was significantly shorter than that of male subjects. 2. Arteries supplying the gracilis muscle were obturator artery (11.0%), medial circumflex femoral artery (100%), first muscular branch of femoral artery (100%), second muscular branch of femoral artery (45.2%), third muscular branch of femoral artery (17.8%), and popliteal artery (9.6%). 3. Medial circumflex femoral artery had 1 -10 pedicles and divided into ascending, transverse and descending branches. The existence of ascending branches were 14.8%, the ascending and descending branches were 22.7%, the ascending, transverse and descending branches were 22.7%, the transverse and descending branches were 22.0%, and the only descending branches were 22.0%. 4. The frist muscular branch of femoral artery pierced the gracilis muscle at a distance which represented 61.9 +/-12.8% of the length from A to B. The external diameter were 1.4 +/-0.4 mm. 5. Obturator nerves reached the gracilis muscle at a distance which represented 29.0 +/-7.4% of the length from A to B. The maximum external width and length were 1.0 +/-0.4 mm and 59.7 +/-25.0 mm, respectively. In conclusion, the length and width of the gracilis muscle in Korean were different depending on gender. These data also provides the anatomical characteristics of the arterial supply of the gracilis muscle in Korean in clinical relevance with musculocutaneous flap

RESUMO

Free -flap which is transferred to recipients is a thin flat tissue isolated from human body and nutrient vessel of free - flap is ligated with similarly sized vessel. Free -flap reconstruction is widely used, due to high rate of flap survival and functional refinements, although it gives disadvantage of long surgery time and inefficient adaptation. This study demonstrates the characteristics and arterial supply of rectus femoris muscle of thigh. Seventy thighs (35 right, 35 left) of the 35 cadavers (19 males/16 females) which were clinically normal and without deformity were dissected and measured, according to Martin measurements. 1. The average length and width of rectus femoris muscle were 396.7 +/-39.9 mm and 36.5 +/-7.9 mm, respectively. The length of female subjects was significantly different from that of male subjects (P 0.05). 2. In the origin and insertion of rectus femoris muscle, anterior tendon and posterior tendon were not different between female and male subjects. 3. Artery of the rectus femoris muscle arises from deep femoral artery. The length of pedicle from the entering point of the rectus femoris muscle was average 19.0 +/-11.9 mm. The length from the entering point of the rectus femoris muscle to spliting point was 13.7 +/-7.7 mm of P1, 12.6 +/-7.5 mm of P2, and 14.8 +/-11.63 mm of P3 pedicles. 4. The frequency of the blood vessels inserted into the rectus femoris muscle was the first highest at the portion of 32.5 ~35% and the second highest of 35 ~37.5% and 37.5 ~40% ranges, when anterior superior iliac spine from center of the patellar was considered as 100% of portion. 5. According to the method by Kimata et al. (1998) classifying perforators based on the anatomic variations, type 1 and VIII were 83.58% and 5.97% respectively. Type 5, 6 and 7 were not observed. 6. Femoral nerves inserted into the rectus femoris muscle were distributed within 7.5 ~45% portion when anterior superior iliac spine from center of the patella was converted into 100%. The portion of 17.5 ~20% had the highest frequency of nerves. In conclusion, length of the rectus femoris muscle in Korean were different depending on gender, whereas tendon lengths were not. These data demonstrate artery pattern in Korean and provide anatomical potential for rectus femoris muscle to be used as a free -flap muscle.

RESUMO

Retinoic acid (RA) is widely used to treat the dermatologic disorders, such as acne and psoriasis, but its usage is limited because of teratogenic effects. Moreover, it is known that RA induces cleft palate by influencing epithelial differentiation and mesenchymal cells in palatine processes. We studied the ultrastructures of the epithelial and mesenchymal cells in rat palatine shelves treated with RA, in comparison with those of the normal developing rat. In this experiment, pregnant Sprague -Dawley rats were treated with 100 mg/kg of all -trans retinoic acid at day 10 of gestation. Pregnant rats were killed at 14 th and 16 th day of gestation. Fetuses were removed and palatine processes were dissected. The specimen were observed with a transmissiom electron microscope. The results were as follows. 1. Palatine epithelium of control rats was made up of two cell layers at day 14 of gestation, and that of RA treated rats consisted of multicellular layers. At the 16th day of gestation, many apoptotic bodies were observed in triangular area of the palatine epithelium of the control rat. In contrast, apoptotic cells were hardly observed in RA treated rats. 2. Mesenchymal cells of control rats contained cytoplasmic process, oval -shaped nucleus, well -developed rough endoplasmic reticulum, Golgi complex, and mitochondria. RA treated mesenchymal cells showed atrophied cisternae of Golgi complex, rough endoplasmic reticulum with sacculated, fragmented and ribosome detached cisternae, mitochondria with dissolved mitochondrial cristae, and multivesicular body. After RA exposure during palatogenesis, the frequency of apoptotic bodies was low in palatine epithelium, and mesenchymal cells were severely damaged. In conclusion, it is suggested the RA may induce direct cytotoxic effects on mesenchymal cells and influence normal apoptosis process in developing epithelium.

RESUMO

This study was designed for the facial reconstruction of Father Dae -Gun (Andrea) Kim, who is the first priest in Korea. The study was entrusted by Seoul great parish, Myeongdong Cathedral and was conducted during 15 months from September 1999. To reconstruct the face of Father Dae -Gun (Andrea) Kim, we used photographs and metric data of Father Dae -Gun (Andrea) Kim's skull, which was measured by Department of Anatomy, Catholic Medical College at 1971. Based on above data, we found a skull similar to Father Dae -Gun (Andrea) Kim, replicated it, and modified it to be consistent with that of Father Dae -Gun (Andrea) Kim measured at 1971. The face of Father Dae -Gun (Andrea) Kim was reconstructed on the modified replica of Father Dae -Gun (Andrea) Kim's skull using the forensic anthropological data about the average skin depth and the relationships of skull morphology to facial features of Korean. The average skin depth of Korean face was obtained from direct measurement of cadavers and indirect measurement of live Korean using ultrasonography. The result of facial reconstruction of Father Dae -Gun (Andrea) Kim was made as the bronze bust. The forensic anthropologic method such as facial reconstruction is one of the methods to identify unidentified -skull. This study is the first facial reconstruction on the base of Korean physical anthropological data and is thought to be helpful to the facial reconstruction for identification.
