Skeletal-injury frequency and distribution are likely to reflect hunting behaviour in predatory vertebrates and might therefore differ between species with distinct hunting modes. Two Pleistocene predators from the Rancho La Brea asphalt seeps, the sabre-tooth cat, Smilodon fatalis, and dire wolf, Canis dirus, represent ambush and pursuit predators, respectively. On the basis of a collection of over 1,900 pathological elements, the frequency of traumatic injury across skeletal elements in these two species was calculated...

BACKGROUND: Robotic-assisted total pelvic exenteration (TPE) can offer a minimally invasive approach to a major multi-organ operation. METHODS: In this video, we summarize a stepwise approach to robotic TPE in a 70 year-old female Jehovah's witness with a history of cervical cancer post-chemoradiation and radical hysterectomy who experienced local recurrence at the vaginal cuff involving the rectum and bladder. RESULTS: The patient was placed in the lithotomy position...

The risk for spinal cord injuries (SCIs) ranging from devastating traumatic injuries, compression due to degenerative pathology, and neurapraxia is increased in patients with congenital spinal stenosis. Classical diagnostic criteria include an absolute anteroposterior diameter of <12-13mm or a Torg-Pavlov Ratio of <0.80-0.82; however, these factors do not take into account the size of the spinal cord, which varies across patients independent of canal size. Recent large MRI studies of population cohorts have allowed newer methods to emerge that account for both cord and canal size by measuring a spinal cord occupation ratio (SCOR)...

BACKGROUND: Isolated uterine didelphys requires no treatment in contrast to cervical agenesis, which requires a hysterectomy. Given this, correct diagnosis of Müllerian anomalies is paramount for making recommendations for patient care. CASE: A 15-year-old presented to clinic with pelvic pain and primary amenorrhea. Uterine didelphys with bilateral cervical agenesis was diagnosed by imaging. Hysterectomy was recommended and diagnosis was confirmed at surgery and by anatomic pathology...

OBJECTIVE: Thyroidectomy is a very common surgical procedure. Regardless of surgeon experience, incidental parathyroidectomy is a complication of thyroidectomy. The aim of this study was to identify the clinical course of incidental parathyroidectomies after thyroidectomy. METHODS: Patients who underwent thyroidectomy between January 2010 and June 2014 were evaluated retrospectively. Pathology reports were reviewed for the presence of parathyroid tissue in the thyroidectomy pathology specimens...

INTRODUCTION AND OBJECTIVES: Radioguided surgery is a minimally invasive surgical technique for the treatment of primary hyperparathyroidism. The goals of our study were to evaluate the rate of success and compare the results with intraoperative histological analysis. METHODS: We retrospectively studied 84 patients with primary parathyroidism who had undergone radioguided surgery. All the patients had a positive parathyroid scintigraphy prior to surgery. An intravenous injection of Tc-99m sestamibi was administered before surgery, and radioguided location of the pathologic parathyroid tissue was performed using an intraoperative gamma probe, applying the "20% rule"...

BACKGROUND: Recent studies suggest that the encapsulated form of follicular variant of papillary thyroid cancer (eFVPTC) behaves more similarly to benign lesions and can be treated with thyroid lobectomy alone instead of total thyroidectomy. To distinguish aggressive cancers from more benign lesions more clearly, the objective of this study was to determine if the eFVPTC behaves less aggressively than the nonencapsulated variant (neFVPTC). METHODS: A prospectively collected endocrine surgery database in our institution was reviewed for all patients with FVPTC on surgical pathology from 1999 to 2012...

The occurrence of Pacinian corpuscles associated to lymph nodes is an anatomical rarity and very scarce information exists in this regard. Here we examined immunohistochemically four Pacinian corpuscles found in the close vicinity of the hiliar blood vessels of lymph nodes (2 cervical, 1 axillary, and 1 inguinal) during routine surgical pathology. Pacinian corpuscles were normally arranged and displayed a pattern of protein distribution as follows: the axon was positive for neurofilament proteins and neuron specific enolase, the inner core cells showed intense S100 protein and vimentin immunostaining while they were negative for glial fibrillary acidic protein, type IV collagen and glucose transporter 1; vimentin, type IV collagen, and glucose transporter 1 were also observed also in the outer-core and the capsule...

BACKGROUND: Multiple dissections rarely occur with ruptured vertebral artery dissecting aneurysms (VADAs). Here, we report three cases of ruptured VADA concurrent with spontaneous cervical internal carotid artery (ICA) dissection. CASE DESCRIPTION: None of the three patients had a history of vasculopathy or trauma. All ruptured VADAs were treated with internal coil trapping in the acute stage of subarachnoid hemorrhage (SAH). Rebleeding was not observed in any patients after the treatment...

Mexico City (MC) young residents are exposed to high levels of fine particulate matter (PM2.5), have high frontal concentrations of combustion-derived nanoparticles (CDNPs), accumulation of hyperphosphorylated aggregated α-synuclein (α-Syn) and early Parkinson's disease (PD). Swallowed CDNPs have easy access to epithelium and submucosa, damaging gastrointestinal (GI) barrier integrity and accessing the enteric nervous system (ENS). This study is focused on the ENS, vagus nerves and GI barrier in young MC v clean air controls...

BACKGROUND: Temporomandibular disorders (TMDs) are prevalent multifactorial pathologies in which the actual role of the cervical region position is controversial. OBJECTIVE: To analyze the relationship between the position of the upper cervical rachis and the symptoms of TMD. METHODS: Sixty women were recruited to this study. All of them completed a questionnaire and were subjected to a temporomadibular exploration to create two different groups: a TMD Group (n= 30) - women who suffered TMD symptoms according to the evaluation; and a control group (n= 30) - women who were free from TMD symptoms...

Human papillomavirus (HPV) 16 is the most common high-risk HPV type identified in oropharyngeal and cervical neoplasia. Recently, HPV-associated oral epithelial dysplasia with specific histopathologic features and demographics similar to HPV-oropharyngeal carcinoma has been identified. The objective of this study was to evaluate histopathologically all cases of HPV-oral epithelial dysplasia seen in one center and identify HPV types in a subset of cases. Cases with specific histopathology for HPV-oral epithelial dysplasia that were positive both by immunohistochemical studies for p16 and by in situ hybridization for high-risk types of HPV were further analyzed using QIAamp DNA Tissue Kits (Qiagen, Hilden, Germany)...

PURPOSE: To evaluate if herpes zoster virus (HZV) reactivation may be considered in the aetiology of cervical radiculopathy. METHODS: The study group was composed of 110 patients (52 M-58F;mean age ± SD:46.5 ± 6.12; range:40-73) with a clinical diagnosis of cervical radiculopathy. Patients with signs of chronic damage on neurophysiological studies were submitted to an X-ray and to an MRI of the cervical spine in order to clarify the cause of the cervical radiculopathy and were investigated for a possible reactivation of HZV; HZV reactivation was considered as "recent" or "antique" if it occurs within or after 24 months from the onset of symptoms, respectively...

REVIEW
Dilip R Patel, Stephen Breisach
Shoulder pain in young athletes generally is a result of poor sports technique and overuse. A number intrinsic causes of shoulder pain have been identified. Pain may also be referred to shoulder area from cervical spine, neck and chest pathology. Overuse stress injury of the proximal humeral physis is important to recognize early in order to prevent later complications. Shoulder impingement syndrome is a general term used to describe multiple underlying lesions and relatively uncommon in young athletes. In adolescent athletes, glenohumeral instability is an important underlying pathomechanical basis for shoulder pain...

Müllerianosis is an embryonic Müllerian disease, resulting in the formation of the benign diseases adenomyosis, endometriosis, endosalpingiosis, and endocervicosis. Endocervicosis primarily affects the bladder, and rarely the cervix. Cervical endocervicosis, which is also a pseudoneoplastic glandular lesion, could be misinterpreted as a premalignant or even a malignant lesion. Because the treatment of these diseases is very different, early clinical diagnosis is important. Unfortunately, however, this lesion is difficult to diagnose preoperatively using clinical and radiological information, and pathological confirmation is needed...

Non-neural granular cell tumors (GCTs) are clinically rare, whereas cases arising in the uterine corpus are exceedingly rare. Only three uterine cervical cases of GCTs have been reported to date and, to the best of our knowledge, there are no reports of GCT of the uterine corpus in the literature. We herein describe the first case of non-neural GCT arising from the uterine corpus reported to date. A 55-year-old premenopausal woman was referred to the Department of Obstetrics and Gynecology of Hashimoto Municipal Hospital (Wakayama, Japan) with a suspected uterine tumor...

Cytologic-histologic correlation (CHC) represents a documented effort to obtain and compare, when available, gynecologic cytology reports with an interpretation of high-grade squamous intraepithelial lesion or malignancy, with the subsequent histopathology report, and to determine the possible cause of any discrepancy. The correlation is influenced by multiple closely interdependent clinical and pathologic factors. Many of these factors including the sensitivity and accuracy of colposcopy-directed biopsy, the diligence of the colposcopist, and the attributes of the cervical lesion represent "preanalytical" factors which can significantly affect the CHC outcome, but are often less emphasized during CHC process...
