Usama Qayyum, Diego Villacis, Charles M Jobin
Pronator teres muscle strain is a rare sporting injury reported thus far only in cricket and golf players. The injury appears to occur when the sporting club or racket strikes the ground during a forceful swing and causes the elbow to experience an eccentric force during resisted elbow flexion and pronation. On initial presentation, this injury can be mistaken for injury to the medial ulnar collateral ligament, or exacerbation of medial epicondylitis. On examination, bruising and tenderness distal to the elbow over the course of the pronator teres are often present...

Zhi Yang Ng, Kyle R Eberlin, Tianyu Lin, Peter T Masiakos, Curtis L Cetrulo
Dog bite injuries are common and the head and neck is most frequently involved in pediatric patients. In severe cases, the combination of crushing, tearing, and puncturing can result in scalp avulsion. Currently, microsurgical replantation of the avulsed scalp remains the gold standard but may not always be possible. The authors present their treatment algorithm with 2 patient examples. In Patient 1, the scalp was deemed unsuitable for replantation due to extensive soft tissue injury; in Patient 2, the scalp was not available on presentation...

BACKGROUND: Surgical treatment for lumbar disc herniation consists of discectomy performed either open or minimally invasive techniques. Endoscopic discectomy using the tubular retractor is been increasingly used as it gives advantage of smaller incision, less tissue injury and faster recovery. The aim of this study was to check its feasibility and learning curve at a tertiary public sector hospital with a large volume load (more than 50 spine surgeries per month) with treatment provided free of cost...

REVIEW
Matthew J Jordan, Per Aagaard, Walter Herzog
The purpose of the present review was to: 1) provide an overview of the current understanding on the epidemiology, etiology, risk factors, and prevention methods for anterior cruciate ligament (ACL) injury in alpine ski racing; and 2) provide an overview of what is known pertaining to ACL reinjury and return to sport after ACL injury in alpine ski racing. Given that most of the scientific studies on ACL injuries in alpine ski racing have been descriptive, and that very few studies contributed higher level scientific evidence, a nonsystematic narrative review was employed...

Hypoplasia of the meniscus is a very rare congenital abnormality, with only a few cases reported to date. A 9-year-old girl visited our hospital due to lateral knee pain following a hyperextension injury to the left knee. Magnetic resonance imaging showed hypoplasia of the medial and lateral menisci, as well as a posterior horn tear of the lateral meniscus, in both knee joints. To our knowledge, this is the first report of a patient with hypoplasia of the medial and lateral menisci in both knee joints.

Acquired nasolacrimal duct obstruction (NLO) causes symptoms of epiphora which can be associated with stickiness, dacryocystitis and interference with tear film causing visual blurring [1]. The annual incidence rate of NLO is 20 per 100,000, with the majority of patients being females above the age of 66 years [2]. While the aetiology is usually unknown, the site of obstruction is more commonly distal and invariably amenable to treatment by DCR surgery [3-4]. Proximal NLO at the level of the cancaliculi is less common but may still be treatable by extended DCR techniques including canalulostomy...

PURPOSE: To investigate effects of punctal occlusion on global tear protein levels in patients with dry eye. METHODS: In this prospective, longitudinal, single-center study, nonabsorbable punctal plugs were inserted bilaterally into the lower punctum of 30 patients with moderate dry eye. Dry eye symptoms, fluorescein corneal staining, Schirmer I test, tear film break-up time, and safety were assessed in the more severe eye. Tear proteins at weeks 1 and 3 were quantified by iTRAQ relative to baseline preocclusion levels...

Purpose: Electrical neurostimulation enhances tear secretion, and can be applied to treatment of dry eye disease. Using a chronic implant, we evaluate the effects of stimulating the anterior ethmoid nerve on the aqueous, lipid, and protein content of secreted tears. Methods: Neurostimulators were implanted beneath the nasal mucosa in 13 New Zealand white rabbits. Stimulations (2.3-2.8 mA pulses of 75-875 μs in duration repeated at 30-100 Hz for 3 minutes) were performed daily, for 3 weeks to measure changes in tear volume (Schirmer test), osmolarity (TearLab osmometer), lipid (Oil-Red-O staining), and protein (BCA assay, mass spectrometry)...
