Jeffrey James Lynch
This study compares the use of 0.05 and 0.10 alpha levels with the updated osteometric pair-matching model on two samples of the os coxa, scapula, and clavicle. The samples include the Forensic Data Bank, and the osteometric sorting reference used within the Defense POW/MIA Accounting Agency. Mixed-effects two-way analyses of variance were used to analyze bilateral asymmetry in the standard measurements. In total, 3,793,566 t-tests were conducted for osteometric pair-matching analysis. The results indicate high levels of exclusion power, and accuracy can be obtained with the os coxa and scapula...

Objectives The aims of this study were to describe the paravertebral brachial plexus (PBP) blockade in cats, and compare the spread of bupivacaine-methylene blue solution (BMS) using two volumes of injection into the PBP. Methods Six cadavers (4.4 ± 1.8 kg) randomly received 0.15 ml/kg (LOW) or 0.2 ml/kg (HIGH) per injection of BMS into the PBP. The first injection was made ventral to the transverse process of the sixth cervical vertebra (nerves C6 and C7) at the emergence of nerve roots. A second injection was performed at the edge of the cranial border of the scapula and directed ventrally towards the first rib (C8 and T1)...

BACKGROUND: Scapular winging resulting from long thoracic nerve palsy is uncommon but debilitating, and the choice of surgical treatment is inconsistent. The autogenous semitendinosus tendon plays a key role as an interposed tendon graft, although its use in the indirect transfer of the sternal head of the pectoralis major during the treatment of scapular winging has rarely been reported. MATERIALS AND METHODS: A retrospective review was performed during a 9-year period from the clinical data of 26 cases (28 shoulders) with indirect transfer of the sternal head of the pectoralis major with the interposition of an autogenous semitendinosus tendon graft for dynamic stabilization of the scapula...

Paget Disease of the bone is a metabolic disorder which leads to a profound alteration of the bone's architecture. It may be asymptomatic and, since its radiological features mimic those of bone metastases, may present a diagnostic dilemma during the evaluation of a cancer patient. We illustrate an uncommon monostotic form of the disease, affecting solely the scapula, diagnosed during the staging of a lung cancer patient.

The sauropod of El Oterillo II is a specimen that was excavated from the Castrillo de la Reina Formation (Burgos, Spain), late Barremian-early Aptian, in the 2000s but initially remained undescribed. A tooth and elements of the axial skeleton, and the scapular and pelvic girdle, represent it. It is one of the most complete titanosauriform sauropods from the Early Cretaceous of Europe and presents an opportunity to deepen our understanding of the radiation of this clade in the Early Cretaceous and study the paleobiogeographical relationships of Iberia with Gondwana and with other parts of Laurasia...

INTRODUCTION: The clinical application of upper limb (UL) three-dimensional movement analysis (3DMA) in children with unilateral cerebral palsy (uCP) remains challenging, despite its benefits compared to conventional clinical scales. Moreover, knowledge on UL movement pathology and how this relates to clinical parameters remains scarce. Therefore, we investigated UL kinematics across different manual ability classification system (MACS) levels and explored the relation between clinical and kinematic parameters in children with uCP...

Small cell neuroendocrine carcinoma (SCNEC) of the tongue is very rare. We here present a SCNEC impatient with distant metastasis. A 74-year-old Chinese male went to hospital to treat a tongue tumor, which was founded at a conventional physical examination in Weifang Stomatology Hospital. The check of positron emission tomography-computer tomography (PET-CT) by Weifang people's hospital revealed a tumor in the right root of tongue, and distant metastasis in the right submandibular area, neck, mediastinum, right hilar, abdominal, retroperitoneal multiple lymph nodes, left thyroid, right lower lung, right scapula and bilateral adrenal...

Objectives Feline injection-site sarcomas (FISSs) are soft tissue tumours typically characterised by an interscapular location and highly infiltrative behaviour. CT is considered the modality of choice for FISS staging and double positioning (dynamic approach) was reported to successfully detect the exact extent of infiltration into the muscles. The aim of the present study was to investigate the utility of the dynamic approach in feline patients referred for preoperative staging of interscapular FISS. Methods Tumour volume estimates were compared between the ellipsoid and the semi-automated segmentation methods...

Dislocation and injury of the biceps is associated with acute and chronic trauma, degenerative changes, repetitive microtrauma, or injuries associated with recurrent and neglected cases of shoulder dislocation. The cases of displaced biceps injuries are relatively rare (only 1/6(th) of all rotator cuff injuries). The dislocation of biceps is manifested with pain and restriction of movements. The X-ray shoulder is not of much help in this condition barring for ruling out the fractures of humerus and scapula...

Chest compression devices for mechanical cardiopulmonary resuscitation (CPR) have become more common. Here, we report the case of a young woman who attempted resuscitated with LUCAS™2 after she was found unconscious at home. At autopsy, we found extensive intramuscular hemorrhages in posterior neck, between the scapulae, and in the lumbar region. Investigation of internal organs showed injuries to the lung, spleen, and kidney. The extension of the injuries gave rise to suspicion of homicide by smothering, which police investigation subsequently did not support...

In vertebrates, skeletal muscles of the body are made up of epaxial and hypaxial muscles based on their innervation and relative position to the vertebral column. The epaxial muscles are innervated by the dorsal branches of the spinal nerves and comprise the intrinsic (deep) back muscles, while the hypaxial muscles are innervated by the ventral branches of the spinal nerves including the plexus and consist of a heterogeneous group of intercostal, abdominal, and limb as well as girdle muscles. The canonical view holds that the epaxial muscles are derived from the medial halves of the somites, whereas the hypaxial muscles are all derived from the lateral somitic halves...

Aspergillosis is a common fungal infection in both wild and pet birds. Although effective antifungal medications are available, treatment of aspergillosis can require months of medication administration, which entails stressful handling one or more times per day. This study examined the delivery of the antifungal drugs itraconazole, voriconazole, and terbinafine to Japanese quail ( Coturnix japonica ) via an impregnated implant. Implants contained 0.5, 3, 8, or 24 mg of itraconazole, voriconazole, or terbinafine...

As the conventional histopathologic examination of thymic carcinoma (TC) is nonspecific, immunohistochemical studies along with correlative radiographic investigations are needed for its correct diagnosis. TC commonly occurs in the late 5th to early 6th decades of life but is extremely rare in childhood. It may be incidentally detected from chest radiographs taken as routine or for other reasons. However, most patients present with symptoms such as chest pain, cough, shortness of breath, dysphagia and hoarseness, which are directly attributable to the mediastinal mass...
