Purpose Most standard textbooks of hand surgery report on the rate of palmaris longus muscle absence of 15%. The aim of the study was to determine the absence of palmaris longus and to correlate it with age, sex and body side. Methods The study included 800 subjects (400 male and 400 female). They were initially asked to do the standard test for the assessment of the palmaris longus tendon. If the tendon was not visualized or palpable, four additional tests were done to confirm its absence. Results Unilateral absence of the palmaris longus was recorded in 173 (21.6%) and bilateral in 127 (15.9%) study subjects. According to body side, right-sided absence of palmaris longus was found in 69 (8.6%) and left-sided in 104 (13%) subjects, yielding a statistically significant difference. Bilateral absence was slightly more common in men. The prevalence of palmaris longus absence on the right and left side was similar in men, whereas in women it was significantly more common on the left side. Differences between the three age groups (young, middle-aged and old) were not significant; however, the middle-aged and young groups showed a lower rate of palmaris longus presence as compared to old-age group. Conclusions It has been suggested that this tendon is rapidly disappearing in humans. The results of our study show a relatively high incidence of tendon absence and pointed to more pronounced loss of the muscle on the left side. © Springer-Verlag 2009. Source

This paper aims to investigate possible application of the rough set approach to table-organized data in the medical domain, which reveals some relationships among sagittal abdominal diameter, anthropometric parameters and cardiovascular risk factors. When applied to table-organized data, the methodology based on the rough set theory is capable of producing decision rules in the form of If-Then rules. Such rules are suitable for inspection, examination and further analysis. By examination of the selected 30 decision rules, sagittal abdominal diameter could point out a group of obese and preobese patients with high content of visceral fat with different combination and composition of cardiovascular risk factors. These results suggest that sagittal abdominal diameter could be a clinically useful marker for identification of risk factors, combination and structure of total cardiovascular risk by applying different rules in obese and preobese persons. © 2010 Elsevier Ltd.

The study was aimed at evaluating the efficacy of diode laser trabeculoplsaty in lowering intraocular pressure in patients with both primary open-angle glaucoma and exfoliation glaucoma by using different size of laser spot. This six-month, unmasked, controlled, prospective study included sixty-two patients with the same number of eyes, who were divided into two groups. Trabeculoplasty was performed with 50 micron and 100 micron laser spot size in the group I and group II, respectively. Other laser parameters were the same for both groups: the wave length of 532 nm, 0.1 second single emission with the power of 600-1200 mW was applied on the 180 degrees of the trabeculum. The mean intraocular pressure decrease in the 50 micron group (group 1) on day 7 was 24% from the baseline and after six-month follow-up period the intraocular pressure decrease was 29.8% (p < 0.001). In the 100 micron group (group II), the mean intraocular pressure decrease on day 7 was 26.5% and after six months it was 39% (p < 0.001). Source


Avulsion fractures of the anterior inferior iliac spine are rare injuries of the pelvic ring and occur during sports activities. Hereby is presented a case of a 22-year-old professional football player who was diagnosed to have an avulsion fracture of the anterior inferior iliac spine on the right side four months after the initial injury and he was treated surgically with the excision of the avulsed fragment. The football player recovered completely and returned to his usual sports activities. Two years later, due to the pain in the hip an x-ray and MR image were made, which established the existence of crescent formation, a heterotopic bone, in the area of the anterior inferior iliac spine, which was surgically removed. Physical and medical therapy was conducted and after four months, the professional athlete was back playing football. Two years after the surgical excision of heterotopic ossification, the patient was completely asymptomatic with the same ROM without any thigh muscle hypotrophy, although isokinetic muscle testing did show some weakness of the thigh extensor muscles. An x-ray did not show any signs of heterotopic ossification. Source


Dysplastic nevus is a risk factor for developing skin melanoma. The aim was to analyze patients with both skin melanoma and dysplastic nevi. A 10-year retrospective analysis (1999-2009) was conducted at the Department for Plastic and Reconstructive Surgery, Clinical Centre Vojvodina. During the observed time interval, of 482 patients treated for skin melanoma, 165 (34.2%) had also dysplastic nevi. Melanoma developed more often de novo (67.9%) and 32.1% by malignant alteration. The most dominant type of melanoma was nodular one (70.3%), the most frequent depth being 3.1-4mm (40.6%). The highest incidence of melanoma (32.1%) was in patients aged from 51 to 60 years. The 5- and 10-year survival rates were 72.7% and 50.3%, respectively. Our results correspond to those found in literature except for the fact that the majority of diagnosed melanomas were of nodular type with worse prognosis. Source
