Purpose: Hands are the chief organs for physically manipulating the environment, using anywhere from the roughest motor skills to the finest, and since the fingertips contain some of the densest areas of nerve endings on the human body, they are continuously used organ with complex functions, and therefore, often gets injured. To prevent any functional loss, a detailed anatomical knowledge is required to have a perfect surgical treatment. Also it is necessary to have a thorough understanding of arrangements of the human extensor tendons and intertendinous connections when tenoplasty or tendon transfer is required. We performed a study of the arrangements of the human extensor tendons and the configuration of the intertendinous connections over the dorsum of the wrist and hand. Methods: A total of 58 hands from Korean cadavers were dissected. The arrangements of extensor indicis proprius, extensor digitorum communis, and extensor digiti minimi tendons and intertendinous connections were studied. Results: The most common distribution patterns of the extensor tendons of the fingers were as follows: a single extensor indicis proprius (EIP) tendon which inserted ulnar to the extensor digitorum-index (EDC-index); a single EDC-index; a single EDC-middle; a double EDC-ring; an absent EDC-little; a double extensor digiti minimi (EDM), a single EDC-index (98.3%), a single EDC-middle (62%), a double EDC-ring (50%), and an absent (65.5%) or a single (32.8%) EDC-little. A double (70.6%) EDM tendons were seen. Intertendinous connections were classified into 3 types: type 1 with thin filamentous type, type 2 with a thick filamentous type, and type 3 with a tendinous type subdivided to r shaped 3r type and y shaped 3y type. The most common patterns were type 1 in the 2nd intermetacarpal space, type 2 in the 3rd intermetacarpal space, and type 3r in the 4th intermetacarpal space. And in the present study, we observed one case of the extensor digitorum brevis manus (EDBM) on the boht side. Conclusion: A knowledge of both the usual and possible variations of the extensor tendon and the intertendinous connection is useful in the identification and repair of these structures.

Purpose: Industrial punch accidents involving fingers cause segmental injuries to tendons and neurovascular bundles. Although multiple-level segmental amputations are not replanted to regain function, most patients with an amputated finger want to undergo replantation for cosmetic as much as functional reason. The authors describe four cases of digital amputation by an industrial punch that involved the reinstatement of the amputated finger involving a joint and neurovascular bundle. Amputated segments were replanted to restore amputated surfaces and distal segments. Methods: A single institution retrospective review was performed. Inclusion criteria of punch injuries requiring replantation were applied to patients of all demographic background. Injury extent (size, tissue involvement), operative intervention, pre- and postoperative hand function were recorded. Result: Four cases of amputations were treated at our institute from 2004 to 2008 from industrial punch machine injury. Average patient age was 32.5 years (25~39 years) and there were three males and one female. Sizes of amputated segments ranged from $1.0{\times}1.0{\times}1.2\;cm^3$ to $3{\times}1.5{\times}1.6\;cm^3$. Tenorrhaphy was conducted after fixing fractured bone of the amputated segments with K-wire. Proximal and distal arteries and veins were repaired using the through & through method. The average follow-up period was thirteen months (2~26 months), and all replanted cases survived. Osteomyelitis occurred in one case, skin grafting after debridement was performed in two cases. Because joints were damaged in all four cases, active ranges of motion were much limited. However, a secondary tendon graft enhanced digit function in two cases. The two-point discrimination test showed normal values for both static and dynamic tests for three cases and 9 mm and 15 mm by dynamic and static testing, respectively, in one case. Conclusion: Though amputations from industrial punch machines are technically challenging to replant, our experience has shown it to be a valid therapy. In cases involving punch machine injury, if an amputated segment is available, the authors recommend that replantation be considered for preservation of finger length, joint mobility, and overall functional recovery of the hand.

Indonesia is a developing country, in most of which the infection rates of Helicobacter pylori (H. pylori) have been reported to be high. However, the prevalence of H. pylori infection in Indonesia has been unexpectedly reported to be low. The purpose of our study was to confirm whether the prevalence of H. pylori infection is low among healthy inhabitants in Northern Jakarta by 13C-urea breath test (UBT), and to examine the association of their lifestyle/environmental factors with H. pylori infection and to identify potential routes of transmission. We recruited a total of 196 subjects from a low-income community in Northern Jakarta, Indonesia. Of them, 193 subjects who completed a questionnaire about their lifestyle/environment and had UBT were included in this study. Odds ratios (ORs) adjusted for sex and age with 95% confidence intervals (CIs) were calculated using logistic regression model. The overall H. pylori infection rate was 15.0%. There was difference in H. pylori infection rates among Buginese (40.0%), Betawi (9.1%), Sundanese (3.7%), and Batak (9.1%). After multivariate analysis, the ORs of intake of soybean milk, cucumber more than one time a week, infrequent hand washing before meals, and alcohol consumption were 0.10 (95%CI: 0.01-0.97), 6.61 (95%CI: 1.87-23.3), 4.10 (95%CI: 1.15-14.6), and 61.9 for former drinkers (95%CI: 1.67-2300.8), respectively. Buginese (OR=7.84; 95%CI: 1.82-33.8) and Batak ethnic groups (OR=20.1; 95%CI: 1.90-213.2) were infected more frequently, compared with Javanese. The H. pylori infection rate in this study was low, as reported previously. After we scrutinized the factors, Buginese and Batak ethnic groups eat food using fingers more frequently than Javanese, Betawi, and Sundanese. In addition, infrequent hand wash practice before meal increased the risk. Our study indicated that person-person transmission was possible in this low prevalence area. The low infection rates of H. pylori among those of Javanese, Betawi, and Sundanese ethnicity could be partly due to sanitary practice.

Purpose: When performing nuclear medicine examinations, body wraps or plastic supports are used to support and immobilize the patient's upper extremities to prevent patient safety accidents. However, the existing plastic supports compromised patient and staff safety, including finger entrapment and falls. Moreover, the body wrap provided by manufacturers compromised image quality such as upper extremities cutoff during whole body bone scan. Therefore, a new design of body wrap was developed to improve the issue, and this study aims to evaluate the usability of this medical body wrap. Materials and Methods: To evaluate the usability of the newly designed medical body wrap, a quality assessment of whole body bone scan images and a user satisfaction survey were conducted. Adult patients (male:female=129:152, age: 60.3±12.4 years, BMI: 24.0±4.2) aged 16 years or older who underwent a whole body bone scan during two periods: June to July 2022 (before improvement, n=139) and June to July 2023 (after improvement, n=142) were randomly selected for image quality evaluation. Five radiotechnologists visually evaluated the posterior view of the whole body bone image, including the left and right elbow (2 points), arm (2 points), whether the hand is extended (2 points), whether the hand is included (2 points), and the number of visible fingers (10 points), with a total of 18 points, which were converted to 100 points and analyzed for difference before and after improvement using an independent sample t-test. The user satisfaction questionnaire was evaluated using a 5-point Likert scale among 16 radiotechnologists from three general hospitals who experienced the new body wrap. Results: The image quality assessment was 82.0±13.8 before the improvement and 89.3±10.1 after the improvement, an average of 7.3 points higher, with a statistically significant difference (t=5.02, p<0.01). The user satisfaction survey showed an overall satisfaction rating of 4.1±0.8 for ease of use, 3.8±0.7 for scan preparation time, 3.9±0.7 for patient safety, 3.8±1.2 for scan accuracy, and 4.2±0.7 for recommendation (87.5% questionnaire response rate). Conclusion: The developed body wrap showed higher image quality and user satisfaction compared to the old method. Considering these results, it is deemed that the new body wrap may be more useful than existing methods.

Post - operative wound infections have been a serious problem in nursing care in the operating room and appear to be strongly related to the infection occurring during the performance of operation. The purpose of this study is to identify patterns in duration of surgical hand scrub (SHS), to evaluate the method of SHS and to examine the rate of glove perforation. Subjects for this study include 244 doctors and 169 nurses working in the operative theatre of a hospital in Seoul area. Test samples and related data were collected from this medical facility between April 1, through 15, and July 1, through 5, 1995 by the author and a staff member working in the operating room. For the study, data on the SHS of doctors and nurses were obtained at the time of operation and multiple batches of surgical gloves worn by the operating doctors were collected after each operation. The duration of SHS was measured with a stop watch and the method of SHS was evaluated according to Scoring Hand Scrub Criteria (SHS Criteria) and expressed as SHS scores. For the analysis of the data, t-test was used to compare the differences in the duration and the SHS scores of doctors and nurses, and Pearson's correlation coefficient was used to examine the relationship between the SHS duration and the SHS scores. The results of the study are summarized as follows. 1) The mean time spent in each SHS was 167 seconds in nurses, and 127 seconds in doctors. The data comparing nurses and doctors indicated that there were significant differences in Our ation of SH S between these two groups (t=5.58, p=.000). 2) The mean time spent in the first SHS was 145 seconds and that in the End SHS, 135 seconds, and there was not a significant difference in the duration of the SHS between doctors and nurses (t=1.44, P=.156). 3) The mean time spent in the SHS by OS (Orthopaedic surgery) doctors was 162 seconds, 150 seconds by NS(Neurologic surgery), 121 seconds by GS(General surgery), 94 seconds by OPH(Opthalmology) and DS(Dental surgery), 82 seconds by URO(Urology), 78 seconds by PS(Plastic surgery) and 40 seconds by ENT(Ear, Nose & Throat) These also showed a significant difference in the duration of the SHS among the medical specialities (t=4.8, P=.0001). 4) The average SHS score of the nurses was 15.2, while that of doctors was 13.1. The statistical analysis showed that t-value was 3.66, p was. 000. This indicates that the nurses actually clean their hands more thoroughly than the doctors do. 5) The average SHS score of NS doctors was 15.5, 15.3 for doctors for OPH,14.3 for OS,12.7 for GS, 12.0 for DS, 11.7 for URO, 10.1 for PS, 7.5 for ENT. Comparison of the average SHS scores from 8 specialties showed that there was a significant differences in the patterns of the SHS (F=5.08, P=.000) among medical specialties. 6) It appears that the operating personnel scrub the palms and dorsum of their hand relatively well, however, less thorough the nails and fingers. 7) The more the operating personnel spend their time in hand scrubbing, the more correctly they clean their hands(r=.6427, P<.001). 8) The overall frequencies of perforation in all post-operative gloves tested was 38 out of 389 gloves (10.3%). The perforation rate for PS was 13%, 12.1% for GS,8.8% for 05, and 3.3% for NS.

Purpose: Deviations of arterial palmar arches in the hand can be explained on the embryological basis. The purpose of this study was to provide new information about palmar arches through cadaver's dissection. The values of the location and diameter in these vessels were analyzed in order to support anatomical research and clinical correlation in the hand. Methods: The present report is based on an analysis of dissections of fifty - three hands carried out in the laboratory of gross anatomy. A reference line was established on the distal wrist crease to serve as the X coordinate and a perpendicular line drawn through the midpoint between middle and ring fingers, which served as the Y coordinate. The coordinates of the x and y values were measured by a digimatic caliper, and statistically analyzed with Student's t - test. Results: Complete superficial palmar archs were seen in 96.2 % of specimens. In the most common type of males, the superficial arch was formed only by the ulnar artery. In the most common type of females, the superficial arch was formed anastomosis between the radial artery and the ulnar artery. The average length of the superficial and deep palmar arch is $110.3{\pm}33.0mm$ and $67.9{\pm}14.0mm$ respectively. Regarding the superficial palmar arch, ulnar artery starts $-16.1{\pm}5.1mm$ on X - line, and $2.5{\pm}24.5mm$ on Y - line. Radial artery appears on palmar side $7.7{\pm}3.2mm$ on X - line, and $20.9{\pm}10.9mm$ on Y - line. But radial artery starts on $6.3{\pm}3.6mm$ on X - line, and $3.4{\pm}5.1mm$ on Y - line. Digital arteries of superficial palmar arch starts on $6.1{\pm}3.7mm$, $33.9{\pm}8.8mm$ on index finger, $1.8{\pm}3.4mm$, $40.1{\pm}7.3mm$ on middle finger, $-3.2{\pm}4.9mm$, $42.6{\pm}7.0mm$ on ring finger, and $-8.9{\pm}5.1mm$, $42.5{\pm}80mm$ on little finger in respective X and Y coordinates. Radial artery of deep palmar arches measured at the palmar side perforating from the dorsum of hand. It's coordinates were $9.7{\pm}4.8mm$ on X - line, $21.7{\pm}10.2mm$ on Y - line. Ulnar artery was measured at hypothenar area, and it's coordinates were $-20.4{\pm}6.3mm$ on X - line, and $30.6{\pm}7.4mm$ on Y - line. Conclusions: Anatomically superficial palmar arch can be divided into a complete and an incomplete type. Each of them can be subdivided into 4 types. The deep palmar arch is less variable than the superficial palmar arch. We believe these values of the study will be used for the vascular surgery of the hand using the endoscope and robot in the future.

Purpose: Many descriptions of the digital arterial anatomy including skin territory of the finger have been published. Relatively few studies on venous architecture of the finger have been performed in this area, in part, attributable to the technical difficulties encountered in dissecting small vessels. The purpose of this study is to present the precise microsurgical anatomy of the vein related to the digital artery and venae comitantes of the components. Methods: Arterial and venous anatomy of their relation to the fingers were examined in 38 specimens of two fresh cadavers and 36 clinical cases. All specimens were evaluated grossly, surgical microscopically, or / and light microscopically to observe the three & two-dimensional structure of the artery and joining vein, evidence of the venae comitantes, and venous valve. Results: No longitudinal venae comitantes along the digital artery were found in any specimens. The size of the venae comitantes of each digital artery was much smaller than other vein, but always existed any level of digital artery. One or two venae comitantes in the digital artery ran spiral, oblique, helical, fibrillar, or irregular branched shape. The authors also found the vein of the finger, that had bicuspid valves, but not in venae comitantes. Conclusion: Recently, venous outflow problem rather than arterial circulation is the most common cause tissue failure after microvascular surgery in the hand. Sometimes, if it is not recognized early, there is an increased risk of tissue damage and loss. The authors concluded that this study presents a useful knowledge for the characterization of the venous structure and evidence for venae comitantes like a venule in the digital artery at varying levels of the finger.
