It’s Saturday night at 3 AM and a 24-year-old heavily pierced and tattooed man presents to triage with multiple lacerations on his arms and legs. In obtaining the initial history, it is found that he was undergoing a body suspension at a local club and “the hooks ripped out.” He indicates that he was advised to “get some stitches” for the wounds. Your mind is trained to ask questions such as, “...

Shot from a revolver from a close range, a bullet pierced the chest of a policeman and entered through the open mouth of a young male person standing behind. The entry wound was found in the cheek mucosa adjacent to the left lower third molar. After hitting and fracturing the body and the ramus of the mandible, the bullet was deflected and was finally lodged in the parapharyngeal space and skul...

We prove that any family of compact convex sets in R which satisfy the (p, q)-property (p ≥ q ≥ d+1) can be pierced with Õ((pq) q−1 q−d ) points for d ≥ 3 and O((pq) q−1 q−2 ) for d = 2. This improves (already for d = 2 and q = 3) the previously best known bound (of Õ(p 2+d)) provided in Alon and Kleitman’s celebrated proof of the Hadwiger Debrunner conjecture (for the case q = d+ 1). We also p...

The trend of body piercing at sites other than the earlobe has grown in popularity in the past decade. The tongue, lips, nose, eyebrows, nipples, navel, and genitals may be pierced. Complications of body piercing include local and systemic infections, poor cosmesis, and foreign body rejection. Swelling and tooth fracture are common problems after tongue piercing. Minor infections, allergic cont...

A young girl first attended for eye examination on January 8, 1953, when she was 9 years of age. The visual acuity of each eye was 6/6, there was no error of refraction, and the fundi were recorded as normal. She was again examined on January 2, 1958, at the age of 14 years, when she was complaining of defective vision in the right eye. This eye had 2-25 D sph. myopia, which accounted for the v...

Leg pain from lumbar disc herniation is a common presentation. However, certain muscular and peripheral nerve variants may present similarly and represent an unrecognized etiology of femoral nerve dysfunction. Such cases might affect the outcome of specific treatment regimes. Therefore, recognition of these variations in anatomy may be useful to the clinician when treating the patient with medi...

We report on a unique combination of multiple variations concerning the pectoral muscles and the left external jugular vein. Specifically, a bilateral hypoplasia of the medial clavicular portion of the pectoralis major muscle was noticed along with the coexistence of total right pectoralis minor aplasia, substituted by loose connective and fatty tissue. Simultaneously, a supernumerary anterior-...

We report the case of a 49 year-old right-handed chef with left shoulder trauma occurred during a football game. The diagnosis was fracture of the distal quarter of clavicle. The patient underwent osteosynthesis using cerclage wire and splint . The patient suffered from pain and hypoesthesia with a deficit in C8-T1 interosseous territory; radiographs objectified pin migration to the cervical sp...

The problem of matching a thick piezoelectric transducer to an air medium is considered and it is concluded that a suitable matching device can be designed and built in the form of a rigid plate, a few millimetres thick and pierced by a closely packed array of horn-shaped channels, the wide mouths of the horns facing the external world and the narrow throats facing the transducer. Design parame...

We prove that P-sel, the class of all P-selective sets, is EXPimmune, but is not EXP/1-immune. That is, we prove that some infinite P-selective set has no infinite EXP-time subset, but we also prove that every infinite P-selective set has some infinite subset in EXP/1. Informally put, the immunity of P-sel is so fragile that it is pierced by a single bit of information. The above claims follow ...
