Pure divergent dislocation of the index and middle finger carpometacarpal joints: A rare case.

A pure divergent dislocation involving the index and middle finger carpometacarpal joints is an extremely rare injury. We present a case of 21-year-old military man, victim of a motor vehicle accident, admitted at the emergency department unable to move his left hand with major swelling. X-rays and CT scan showed a dorsal dislocation of second and palmar dislocation of the third carpometacarpal joints without associated fracture, In the Operating room under general anesthesia, patient underwent closed reduction and internal fixation with percutaneous K-Wires followed by cast immobilization during 6 weeks. Physiotherapy was started progressively after k-wires removal. At two months follow-up, results were excellent and patient has recovered all of his range of motion and hand activities, at one-year follow-up he was able to perform all military exercises such as pumping and climbing.

[Alprostadil (PGE 1) and cyclosporin A in treatment of vasculitis in rheumatoid arthritis]. / Alprostadil (PGE 1) und Cyclosporin A zur Behandlung der Vaskulitis bei rheumatoider Arthritis.

A 56-year old female patient with rheumatoid arthritis and histologically verifiable vasculitis with necrosis around the nail bed and distal phalanx gangrene on both hands as well as skin ulcers on both thighs was treated over 16 weeks with Cyclosporin A, glucocorticoids and Alprostadil. This immunosuppressive therapy resulted in a clinically relevant improvement of acral microperfusion with complete remission of nail bed necrosis and of gangrenous distal phalanxes. Due to improved tissue perfusion the deep ulcers on both thighs could granulate and were closed by proliferative connective tissue, and the high-positive immunological parameters CIC, CRP and the number of activated T-cells normalized.

High free and latent collagenase activity in psoriatic arthritis synovial fluids.

Collagenase activity has been studied intensively in SF from OA and RA patients. Less is known about collagenolytic activity in PsA SF. Therefore we examined collagenolytic activity in crude and trypsin treated SF as well as the alpha 1-antitrypsin and alpha 2-macroglobulin concentrations in 50 patients suffering from OA (n = 13), RA (n = 17), and PsA (n = 20). Free collagenolytic activity was low in the crude OA SF (1.80 +/- 1.35 micrograms released collagen/min/ml SF) and almost equally low in RA SF (2.35 +/- 1.80 micrograms released collagen/min/ml SF; P > 0.3). The PsA SF, however, exhibited a significantly higher free collagenolytic activity (5.63 +/- 5.69 micrograms released collagen/min/ml SF; P < 0.05 in comparison to OA and RA SF). The treatment of the SF with trypsin further activated collagenolytic activity in each group (OA 2.17 +/- 1.35 micrograms released collagen/min/ml SF; RA 6.48 +/- 6.73 micrograms released collagen/min/ml SF; PsA 11.24 +/- 5.02 micrograms released collagen/min/ml SF) and yielded significant differences between OA and RA, OA and PsA, and RA and PsA SF (P < 0.05). Concomitantly with the collagenolytic activity, the alpha 1-antitrypsin and alpha 2-macroglobulin concentrations of the SF were measured. In SF from patients with PsA (172.9 +/- 69.4 mg/100 ml) and RA (190.6 +/- 64.7 mg/100 ml) the alpha 1-antitrypsin was significantly higher than in those from OA SF (106.1 +/- 39.2 mg/100 ml).(ABSTRACT TRUNCATED AT 250 WORDS)
