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.

The results of our study show that a right-sided absence was more common in left-handed persons while the left-sided absence was more common in right-handed persons. Unilateral tendon absence was more common on the non-dominant hand.

Being considered an exclusive human structure for a long time, fibularis tertius (FT) is believed to have a secondary function of foot dorsiflexion and eversion. This study is an attempt to approach the issue from an anatomical perspective. A systematic literature search identified 35 studies (7601 legs) which met the inclusion criteria. The weighted results of FT presence were as follows: an “adult cadaveric” frequency of 93.2% and a clinical frequency of 80%. The most common FT origin and insertion sites were the distal half of fibula and the base of the 5th metatarsal, respectively. In 95% of cases, an accessory fibular muscle was detected when FT was lacking. We demonstrated that the discrepancy found between the adult cadaveric and clinical frequency values would point out a probable bias in interpreting previous kinesiological results. On an evolutionary level, comparative anatomy demonstrated a very low FT prevalence among monkeys while reaching a frequency of 30% in gorillas, the only non-human apes having an almost exclusive terrestrial locomotion. The consistent prevalence among humans and the presence of similar functional muscles when it is missing would support an essential role of FT during the phylogenetic development of the erect bipedal posture and probably during gait.

This study addressed the issue of medication compliance in general, compliance with antihypertensive therapy, and the relationship between these two groups. In addition to determining the reasons for noncompliance with therapy prescription, the aim of this study was to also establish whether it was considered feasible by the patients to comply with their physician's instructions and whether the patients believed that the prescribed therapy was beneficial to their health. Hypertensive patients were compared to the total study population according to age groups. The study was designed as a cross-sectional survey with the use of a 33-item self-administered questionnaire. The study included 635 individuals who were collecting or buying drugs for the treatment of chronic diseases, with special reference to subjects taking antihypertensive agents (n = 361). More than half (n = 361; 56.9%) of the 635 study subjects were on therapy for arterial hypertension and possibly for some other diseases. The great majority of study subjects reported forgetfulness as the main reason for skipping drug doses. Comparison between the total study population and the subjects treated for arterial hypertension according to age groups (compliant, noncompliant and all together) yielded no statistically significant difference. We concluded that there was no difference in medication compliance between the general patient population and patients receiving antihypertensive therapy and there was no correlation between medication compliance and age.

Our results suggest that the calculation of breast volume or its part in vivo from systematic series of CT scans using the Cavalieri principle or 3D breast reconstruction is accurate enough to have a significant clinical benefit in planning reconstructive breast surgery. These methods can help the surgeon guide the choice of the most appropriate implant or/and flap preoperatively.

There are only nine basic patterns of middle upper extremity venous anatomy. Some are more common than others. This knowledge should help those needing venous access for medical procedures (venepuncture, transfusion, infusion, cardiac catheterization, placement of dialysis access).
