Chiropractic sympathectomy: carotid artery dissection with oculosympathetic palsy after chiropractic manipulation of the neck.

The clinical association between carotid artery dissection and oculosympathetic palsy is well-known. However, the occurrence of this combination with chiropractic manipulation of the cervical neck is rare. We describe the case of a 54-year-old Caucasian American male who underwent cervical manipulation for neck pain. The following day he noticed drooping of his left eyelid, with an unequal pupil size. Imaging later confirmed carotid artery dissection. Only three previous cases (one from the United States ), of an association between carotid artery dissection and chiropractic sympathectomy (oculosympathetic palsy after chiropractic manipulation of the neck) have been reported. Pictures of the oculosympathetic palsy, computed tomography of the head and magnetic resonance imaging of the dissection are presented.

Note: Multi channel Doppler tuned spectrometer to study highly charged ions.

We describe the design and implementation of a multi channel Doppler tuned spectrometer setup to study physics of highly charged ions at high resolution in a direct way. A unique Soller slit assembly coupled with a long one dimensional position sensitive proportional counter enables us to get distinct x-ray peaks at different angles, which allows us to cover large number of angle in one shot. By using this setup, 1s2s (3)S1 - 1s(2) (1)S0 M1 transition in He-like Fe has been resolved from its satellite line 1s2s2p 4P(5/2)° - 1s(2)2s (2)S(1/2) M2 transition in Li-like Fe and measured the lifetime of their respective upper levels with high precision.

The chopstick-noodle twist: an easy technique of percutaneous patellar fixation in minimally displaced patellar fractures.

We report six cases of minimally displaced two-part patellar fractures with skin injury over the patella that were treated with percutaneous K wire fixation and compression applied using stainless steel (SS) wire. This technique makes it possible to perform early operative treatment in cases where unhealthy skin is not amenable to conventional tension band wiring. The technique employs two K wires inserted through the two fracture fragments under local or regional anaesthesia. They are then compressed using simple SS wire knots at the two ends - making it look like noodles at the end of two chopsticks. The fixation is subsequently augmented with a cylindrical plaster-of-Paris cast. The technique is simple, cheap and does not cause soft tissue injury.
