The acetabular labrum and the transverse acetabular ligament form a continuous ring of tissue on the periphery of the acetabulum that provides a seal for the hip joint and increases the surface area to spread load distribution during weight-bearing. When a labral tear is suspected, the treatment algorithm always begins with conservative management, including physical therapy and nonsteroidal anti-inflammatory drugs. When conservative management fails, patients become candidates for arthroscopic labral repair...

Management of proximal and distal biceps tendon pathology is evolving. The long head of the biceps tendon, if inflamed, may be a pain-producing structure. In appropriately indicated patients, a symptomatic long head of the biceps tendon can be surgically managed via tenotomy, tenodesis, and/or superior labrum anterior to posterior repair. In some patients, primary superior labrum anterior to posterior pathology can be managed via biceps tenodesis. Determining which procedure is most appropriate and which technique and implant are preferred for a given patient with biceps tendon pathology is controversial...

Background: Normal histologic architecture of acetabular labrum, regarding presence of Free Nerve Endings (FNEs) and Nerve End Organs (NEOs) has been four times described. Nevertheless, elderly cadaveric specimens and individuals were recruited, leading to considerably high unreliability probability due to microscopic degenerative alterations. Aim of this paper is to analyze distribution pattern of FNEs and NEOs in acetabular labra of healthy middle-aged individuals, configuring thus more reliably acetabular labrum microscopic profile...

Background/Objective: Impingement syndromes are a common cause of shoulder pain in overhead athletes. Anterior internal impingement is a recently suggested mechanism for activity-related pain of the shoulder. Impingement syndromes were initially described to occur due to repetitive or excessive contact between the rotator cuff and other structures in the shoulder. Methods: This is a retrospective, clinical case study reporting 54 consecutive cases of anterior internal impingement in overhead athletes, of which 28 (51...

The Afrotropical genus Eurypeza Lacroix, 2006 (Coleoptera: Scarabaeidae: Melolonthinae: Tanyproctini) was established for one species, Eurypeza evansi Lacroix, 2006, from Somalia. The genus belongs to the first group of Afrotropical Tanyproctini sensu Lacroix (2007), and is characterized by protarsomeres 1-4 and mesotarsomeres 1-4 broadened and ventrally macrosetaceous, protarsomere 5 and mesotarsomere 5 simple, and labrum transverse and shallowly bilobed. The genus Eurypeza differs from other genera of Lacroix's (2007) first group by club with five antennomeres, antennomere 3 and 4 of equal length, labial palpi with three palpomeres, clypeus broadly rounded, protibia bidentate with proximal tooth well developed, and metatibial carina incomplete (for details, see also Lacroix 2006, 2007)...

The insect repellent N,N-diethyl-3-methylbenzamide (DEET), is a multimodal compound that acts as a spatial repellent as well as an irritant (contact repellent), thus being perceived by the insect's olfactory and gustatory systems as an odorant and a tastant, respectively. Soon after DEET was developed, almost 6 decades ago, it was reported that it reduced mosquito feeding on blood mixed with this repellent. It is now known that the mosquito proboscis senses contact repellents with the tips (labella) of the labium, which remain in direct contact with the outer layers of the skin, while the stylets, including the feeding deterrent sensor (labrum), penetrate the skin...

BACKGROUND: Failure of glenoid labrum and capsular healing after glenohumeral dislocation can lead to persistent shoulder instability. The purpose of this study was to determine the effect of nonsteroidal anti-inflammatory drugs (NSAIDs) on the healing glenoid labrum and capsule after glenohumeral dislocation in a rat model. METHODS: Sixty-six rats had surgically induced anterior-inferior labral tears and anterior glenohumeral dislocation. Postoperatively, the animals were assigned to either normal (n = 32) or ibuprofen drinking water (n = 31)...

Although several studies have been published regarding the morphology and anatomical variations of the human shoulder joint, most have dealt with adult individuals. Those looking into the development of the joint have been focused on specific structures or have observed specimens in advanced gestational stages. The goal of this paper is to perform a complete analysis of the embryonic and early fetal development of the elements in the shoulder joint, and to clarify some contradictory data in the literature. In our study, serial sections of 32 human embryos (Carnegie stages 16-23) and 26 fetuses (9-13 weeks) were analyzed...

BACKGROUND: The postoperative course after arthroscopic superior labrum anterior to posterior (SLAP) repair using suture anchors is accompanied by a prolonged period of pain, which might be caused by constriction of nerve fibres. The purpose was to histologically investigate the distribution of neurofilament in the superior labrum and the long head of the biceps tendon (LHBT), i.e. the location of type II SLAP lesions. METHODS: Ten LHBTs including the superior labrum were dissected from fresh human specimen and immunohistochemically stained against neurofilament (NF)...
