MPV is higher in type 2 diabetic patients than in non-diabetic patients. Among type 2 diabetic patients MPV is higher in those who have microvascular complications (retinopathy or microalbuminuria).

Acupuncture has gained increasing attention in the treatment of chronic pain. The lack of a satisfying placebo method has made it impossible to show whether needling is an important part of the method or whether the improvement felt by the patient is due to the therapeutic setting and psychological phenomena. Also, the effectiveness of acupuncture has not been demonstrated sufficiently. We treated 52 sportsmen with rotator cuff tendinitis in a randomised single-blind clinical trial using a new placebo-needle as control. Patients were treated for 4 weeks. The primary endpoint of the trial was the change in the modified Constant-Murley-score from the baseline. Assessment of the treatment outcome was made by experienced orthopaedists not informed of the treatment allocation. Acupuncture with penetration of the skin was shown to be more effective than a similar therapeutic setting with placebo needling in the treatment of pain. The acupuncture-group improved 19.2 Constant-Murley-score points (SD 16.1, range from -13 to 50), the control-group improved 8.37 points (SD 14.56, range from -20 to 41), (P=0.014; C.I. 2.3;19.4). This study showed that needling is an important part of the acupuncture effect in the treatment of chronic shoulder pain in athletes. No conclusions can be derived from this study concerning the importance of choosing points and the rules of Traditional Chinese Medicine. Using the new placebo method as control for other ailments could improve the evidence of specific acupuncture effects beyond pain treatment.

The finding of a normal or inflamed vermiform appendix within an inguinal hernia is termed Amyand's hernia. It is extremely rare in children, especially in infants and neonates. When it occurs, it is usually misdiagnosed as an irreducible or strangulated inguinal hernia, and the accurate diagnosis is made intraoperatively. We report two cases of Amyand's hernia in premature neonates. Both patients presented on admission with signs and symptoms indicating a strangulated right inguinal hernia, and the accurate diagnosis was made intraoperatively. One of them had progressed to local peritonitis. Appendicectomy and hernia repair were made at the same time through an inguinal transverse incision, and the postoperative course was uneventful in both. We point out the need to consider acute appendicitis in the differential diagnosis of strangulated right inguinal hernia.

The aim of this study was to examine the acute effect of front crawl sprint resisted swimming with different added resistances on the kinematic characteristics of the stroke and the orientation of the hand. Ten female swimmers swam four maximal trials (25 m) with small, moderate, large, and no added resistance respectively. Four camcorders were used to record the underwater motion of the right hand and digitizing was undertaken using the Ariel Performance Analysis System. Stroke rate, the stroke length, and mean swimming velocity were significantly decreased, whereas the total duration of the stroke and the relative duration of the pull and push phases were significantly increased during resisted swimming. The increase in the total duration of the stroke was accompanied by an increase in absolute pull length, while no alterations were observed in relative pull length or medial-lateral displacements of the hand. Moreover, the mean resultant velocity of the hand, as well as the pitch and the sweepback angles of the hand were not modified. In conclusion, resisted swimming appears to be a specific form of training, at least regarding its acute effect, although long-term effects should be investigated further.

Pulmonary hydatidosis is more frequently encountered in children than in adults. Chemotherapy with oral administration of particular antihelminthic agents (mebendazole and albendazole) has proved to be effective. This treatment, however, may be associated with serious complications that require surgical management. The aim of this study was to define the limitations of medical treatment, the subsequent complications, and their management. During a 16-year period (1985-2001), 36 children with pulmonary hydatidosis (Echinococcus cysticus) were medically treated. Oral antihelminthic agents (mebendazole until 1992 and albendazole thereafter) were given to all these patients. During this treatment, 11 patients developed complications requiring surgical intervention. In seven children, pleural empyema, or the presence of inflammatory residual fluid, was noted. The remaining four developed pulmonary abscess combined with fluid collection within the pleural cavity. In all complicated cases, the mean size of the cysts exceeded 6 cm in diameter at the beginning of medical treatment. At operation, suturing of communicating bronchi was insecure due to inflammation. Postoperatively, three patients had air leakage from the bronchial tree, requiring continuous suction and prolonged hospitalization. One patient presented with pneumothorax 4 months postoperatively and was operated on again. Overall, long-term results were good. We concluded that a) large pulmonary hydatid cysts should not be treated medically, b) incomplete expectoration of the cyst contents after the parasite death may lead to infection through bronchial communication, and c) patients surgically treated for complications following medical treatment are hospitalized twice as long as patients surgically treated in the first place.
