In this article we describe a unique and complex variation in the arterial pattern of the left hand of a female cadaver. The following variations were found in this case: a) persistent median artery of the palmar type, terminating in the hand as the princeps pollicis and radialis indicis arteries; b) the ulnar artery giving only two common palmar digital arteries; c) the second digital palmar artery without division into two digital branches and instead supplying only the radial side of the ring finger; d) absence of the first common digital artery with the contiguous sides of the second web space supplied by the first palmar metacarpal artery from the deep palmar arch; e) early bifurcation of the median nerve proximal to the flexor retinaculum.

The aim of the study was to evaluate the effect of rehabilitation treatment to improve the treatment results of patients operated for ganglions of the wrist. We studied the hands of 77 patients with ganglions of the wrist. 43 women and 34 men aged between 16 and 98 years participated in the study. The open method was used in the surgical treatment to remove the wrist ganglions in all the patients. In the post-operative treatment 46 patients (group I) underwent hand rehabilitation treatment under the supervision of the authors and 31 patients (group II) did not undergo such a treatment. The examination was carried out on all the patients before surgery and at weeks 1 and 4 after surgery. The patients with ganglions of the wrist and pain, impaired hand mobility and impaired hand efficiency were qualified for the surgical treatment. In the rehabilitation treatment stretching exercises were performed as well as loosening and stabilizing the hand and teaching the patients the correct positioning of the upper limb during work and physical activity. The results were statistically analyzed using non-parametric tests such as the chi-square test, signs test and Mann-Whitney test. It was found that in patients after surgical removal of the wrist ganglion rehabilitation treatment has led to the resolution of pain syndromes, movement disorders and efficiency of hand.

Background. Alcohols are the most commonly used active substances in preparations for quick hand disinfection. They should be bactericidal in very short contact time. PN-EN 13727 + A2: 2015-12 standard, for testing hygienic and surgical handrub disinfection preparations, provides mandatory test conditions of disinfectants in contact times with the range of 30 s to 60 s (hygienic handrub disinfection) and 60 s to 5 min (surgical handrub disinfection). A short contact times for hand hygiene products require a short time of neutralization process. For contact times less than or equal to 10 minutes, the estimated neutralization time is 10 s ± 1 s. Neutralization is a process that abolishes the action of disinfectants. Correct application of this process allows for proper use of disinfectants in practice and its biocidal effect. Objectives. Verification of the effectiveness of 10-second neutralization time of alcohol based preparations for hygienic handrub disinfection. Materials and Method. Neutralization of two products with different ethanol content (89% and 70%) for hygienic handrub disinfection according to PN-EN 13727 + A2: 2015-12 was investigated. The effectiveness of the neutralizer was assessed by determining toxicity of neutralizer, activity of residual effects of the tested products and their derivatives produced during neutralization (10 s) for test organisms (Staphylococcus aureus ATCC 6538; Pseudomonas aeruginosa ATCC 15442; Enterococcus hirae ATCC 10541; Escherichia coli K12 NCTC 10538). Results. The 10-second neutralization time was sufficient to eliminate the residual activity of products for hygienic handrub disinfection with differentiated ethanol concentration. The neutralizer used did not show toxicity to bacteria and did not produce toxic products with tested preparations after neutralization. Conclusions. The use of 10-second neutralization time allows in a precise way designate the contact times for hygienic handrub disinfection products.

The purpose of this study was to evaluate the effect of physical exercise on limited locomotion in the hands of patients who underwent surgery to correct Dupuytren’s contracture. We studied the hands of 84 patients with Dupuytren’s contracture aged from 30 to 84 years. In all patients, the contracture was removed by performing a partial fasciectomy. Physical exercises were carried out a week prior to surgery and during the postoperative period. Patients were divided into group I, in which the exercise was carried out under the supervision of the authors of this study and group II, in which exercises were performed sporadically and without professional supervision. Measurements were performed on all patients one week before surgery (A), 1 week after surgery (B) and 6 weeks after (C). The range of movement of fingers was measured using a goniometer. The average total loss of finger extension was evaluated, taking due account of the extension loss in the MCP, PIP and DIP joints of all fingers of the treated hand. Rehabilitation treatment included active and passive exercises; in more severe cases the treatment of choice was massage and special equipment to help bear flexion contracture. Test results were statistically analyzed. In all patients, there was an increase in mobility of the fingers. Patients taking part in physical exercise had significantly greater range of finger movement.

This study was performed to investigate the anatomy and variations of the human extensor tendons of the fingers and their intertendinous connections. Ninety five upper limbs of adult cadavers were dissected. The variations in the extensor tendons of the fingers, both proximal and distal to the extensor retinaculum, and their mode of insertion were observed. Also, the intertendinous connections were explored and the obtained data were analysed. The extensor pollicis longus and brevis tendons were found to be single, doubled or, rarely, absent. Their insertion could be traced to either the proximal phalanx, or through the extensor expansion to both phalanges, or rarely to the distal phalanx of thumb. The extensor indicis had a single tendon in all specimens. In the majority of specimens, extensor digitorum had no independent slip to the little finger; it gave off a single tendon to the index, double tendons to the middle finger and triple tendons to the ring finger. Extensor digiti minimi muscle often had double or triple tendons distal to the extensor retinaculum. Three types of juncturae tendinum (JT) were identified between the tendons of extensor digitorum in the 2nd, 3rd and 4th intermetacarpal spaces (IMS) of hands. Types 1 and 2 JT were seen in the three IMS. Type 3 JT was the most frequently identified of all juncturae and was always absent in the 2nd IMS. The percentages of the present data were compared with other researchers’ data. (Folia Morphol 2013; 72, 3: 249–257)

Introduction. Comprehensive therapy of rheumatoid arthritis (RA), apart from pharmacological treatment, also necessitates an implementation of specialized procedures aimed at improving the mobility, stamina and strength of affected joints. Physical treatments used for the rehabilitation of patients with RA are most often related to thermal stimuli and change the temperature of the tissues. Each change of that kind is linked to the adequate vascular reaction and the changes in blood circulation within the affected area. Aim of the Study. The aim of this present study was to examine vascular changes in rheumatoid hand occurring as a physiological response to the mild thermal stimulus being applied, accounting for individual differences in its progress. Material and Methods. The research embraced 32 patients aged 54.9 ± 6.8 with diagnosed RA according to the standards of American College of Rheumatology. For physical therapy a conventional infrared lamp emitting A, B, C waves with a red colour filter was used. The area under treatment was the dorsal side of the hand. Each subject had eight thermographic pictures taken at the pre-defined time intervals: before the application, immediately after the application, and 5, 15, 30, 45, 60 and 120 minutes after the application. Results. The results were shown in a form of graphic reaction progress of the heated and unheated (contralateral) hand. Average static temperatures of both hands did not show any differences (31.8 ± 1.7°C – heated hand; 31.9 ± 1.8°C – unheated hand). Maximum temperature was obtained immediately following the IR lamp application: 35.0 ± 1.2°C for the heated hand and 32.2 ± 2.1°C for the unheated one. Among all analyzed diagrams showing reaction progress following IR application, four individual groups with the most similar results were formed. Conclusions. For all the patients in the study, a comparable decrease in tissue temperature initially increased by IR application was noted within the next 45 minutes following the application. No subject observed any undesirable reactions.

Background. Use of pesticides has been documented to lead to several adverse health effects. Farmers are likely to be exposed to pesticides through dermal exposure as a result of mixing, loading, and spraying. Organophosphate pesticides (OPs) are widely used in most of the agricultural areas throughout Thailand. OPs are cholinesterase inhibitors and blood cholinesterase activity is used as a biomarker of OP effects. Objective. This study aims to determine the association between blood cholinesterase activity and organophosphate pesticide residues on chili farmer’s hands and their adverse health effects. Materials and Methods. Ninety chili farmers directly involved with pesticide applications (e.g. mixing, loading, spraying) were recruited and were interviewed face to face. Both enzymes, erythrocyte acetylcholinesterase (AChE) and plasma cholinesterase (PChE), were tested with the EQM Test-mate Cholinesterase Test System (Model 400). Hand wipe samples were used for collecting residues on both hands and OP residues for chlorpyrifos and profenofos were quantified using gas chromatography equipped with a flame photometric detector (GC-FPD). Results. The average activity (±SD) of AChE and PChE was 2.73 (±0.88) and 1.58 (±0.56) U/mL, respectively. About 80.0% of the participants had detectable OP residues on hands. The median residues of chlorpyrifos and profenofos were found to be 0.02 and 0.03 mg/kg/two hands, respectively. Half of participants reported having some acute health symptoms within 48 hours after applying pesticides. When adjusted for gender, number of years working in chili farming, and frequency of pesticide use, AChE activity (Adjusted OR = 0.03, 95%CI: 0.01-0.13) and detected OP residues on hands (Adjusted OR = 0.15, 95%CI: 0.02-0.95) were significantly associated with having health effects, but no significant association was found in PChE activity (Adjusted OR = 2.09, 95%CI: 0.63-6.99). Conclusions. This study suggests that regular monitoring for blood cholinesterase and effective interventions to reduce pesticide exposure to prevent health effects should be provided to chili farmers.

Structure of the manus and pes has long been a source of confusion in ankylosaurs, owing to the imperfect preservation or complete lack of these parts of the skeletons in most specimens, and the fact that many species appear to have undergone a reduction in numbers of digits and phalanges. New specimens of Pinacosaurusfrom Alag Teeg in Mongolia confirm that the phalangeal formula of the manus is 2−3−3−3−2. However, there are only three toes in the pes, which has a phalangeal formula of X−3−3/4−3/4−X. Importantly, the number of phalanges in the third and fourth pedal digits can vary between either three or four per digit, even within the same specimen. The Alag Teeg site has yielded as many as a hundred skeletons of the ankylosaur Pinacosaurus, most of which were immature when they died. Each skeleton is preserved in an upright standing position, with the bones of the lower limbs often in articulation. The remainder of the skeleton, including the upper parts of the limbs, is generally disarticulated and somewhat scattered. Based on the presence of large numbers of juvenile Pinacosaurus specimens at Alag Teeg, as well as other Djadokhta−age sites (Ukhaa Tolgod in Mongolia, Bayan Mandahu in China), it seems juvenile Pinacosaurus were probably gregarious.

With the use of electrogoniometers wrist positions and movements were measured in 13 milkers while working in a modern rotary milking system. The rotary system put considerable demands on the wrists and hands regarding both velocities and repetitiveness. Values were found close to those described in other repetitive industrial work with high risk of wrist and hand disorders. For the right hand the repetitiveness was 0.57 Hz and 0.46 Hz for the left hand. In addition, the median value (50th percentile) of the angular velocity distribution was also high, being 36°/s for the right hand and 26°/s for the left, and with respect to the peak value (90th percentile) the corresponding values were 155°/s and 135°/s, respectively. Furthermore, when milking in the rotary system, there was less possibility to hold the hands still than in the other milking systems. The right hand rested only 1.4% of the milking time and the left only 1.0%. The hands were therefore moving throughout almost the entire milking procedure. High velocity, repetitiveness and fewer opportunities for rest are risk factors that might lead to disorders in the wrists and hands. Regarding wrist positions, the left wrist was held in a more dorsiflexed position than the right, 37° and 29°, respectively. Compared with tethering and loose-housing parlour milking, the wrist positions were, however, improved in the rotary system. When introducing new milking systems these negative effects on wrist and hand movements must be borne in mind in order to minimize the prevalence of wrist and hand disorders.
