Dynamic muscular endurance in primary fibromyalgia compared with chronic myofascial pain syndrome.

The objective of the study was to quantify the voluntary dynamic muscular endurance (DME) in patients with primary fibromyalgia (PF) since easy fatigability of muscles is one of the major symptoms in this syndrome. Consecutive outpatients referred to a rheumatology clinic specializing in PF were investigated. Thirty-six patients with PF were compared with 18 patients with chronic myofascial pain (CMP) syndrome. Subjects were matched according to gender, age, height, weight, peak torque, and contractional work. The DME was defined as the number of repeated knee extensions necessary for the contractional work in two successive knee extensions to be equal to or below 70% of the initial value measured with an isokinetic dynamometer. A significantly lower DME was found in the PF group than in the CMP group: 11 (7-13) and 18 (11-25), respectively (median and quartiles), p less than .005. Patients with PF have a low voluntary muscular endurance compared to CMP patients.     

Results of pulmonary resection for lung cancer in Norway, patients older than 70 years.

OBJECTIVE: Surgical resection for lung cancer is the mainstay of curative treatment, but studies regarding postoperative results and long term outcome in the elderly have differed. The purpose of the present study was to assess the early and long-term results of surgical resection in patients more than 70 years of age. METHODS: In Norway all clinical and pathologic departments submit reports on cancer patients to the Cancer Registry of Norway. This investigation included all patients more than 70 years of age resected for lung cancer in the time period 1993-2000. For results of long-time follow-up only patients operated on between 1993 and 1998 were included. RESULTS: A total of 763 patients (541 men) were identified aged 71-87 years. Postoperative mortality rate was 9%, highest after bilobectomy and pneumonectomy. The most commonly reported causes of postoperative death were pneumonia and cardiac complications. The majority of patients had tumor categorized as clinical stage (cStage) Ia and Ib. More than 100 in each of these groups proved to have more advanced disease postoperatively (pStage). The 5-year relative survival rate was significantly better in patients with disease in pStage I compared to higher stages. Women had a significantly better 5-year survival rate compared to men, 62.8 and 35.7%, respectively. CONCLUSIONS: Lung cancer surgery appears to be a relatively safe procedure even in the elderly. There is a high postoperative mortality after bilobectomy and pneumonectomy. However, when old people survive the postoperative period the long term prognosis seems favorable.     

A European multicenter study of chronic graft-versus-host disease. The role of cytomegalovirus serology in recipients and donors--acute graft-versus-host disease, and splenectomy

A group of 466 leukemic bone marrow transplanted patients were reported from 17 European bone marrow transplantation teams. Of these, 285 survived more than 3 months and could be evaluated for chronic GVHD. The cumulative incidence of chronic GVHD was 32% two years after BMT. The following factors were statistically significantly associated with chronic GVHD in bivariate analysis: high donor and recipient age, splenecacute GVHD, pretransplant seropositivity to CMV among the recipients and the donors, and donor seropositivity to 3 or 4 different herpesviruses, compared with 0-2, prior to BMT. In multivariate analysis pretransplant recipient CMV seropositivity in combination with donor CMV seropositivity prior to BMT (P = 0.0006), a previous grade II-IV acute GVHD (P = 0.001), and splenectomy (P = 0.01) were significantly associated with chronic GVHD. Thus, in addition to acute GVHD, CMV immune donor cells may be triggered by latent CMV in the recipient, which may play a role in the triggering of chronic GVHD. The possible role of splenectomy in GVHD is also discussed.     

Electroconvulsive therapy and brain damage: the Ontario Supreme Court hearing of the evidence

The issue of whether electroconvulsive therapy (ECT) causes brain damage was examined by the Supreme Court of Ontario when an involuntarily hospitalized patient attempted to overturn a treatment order for ECT made by a review board. The Ontario Mental Health Act (MHA) specifically prohibits the authorization of psychosurgery by a review board. In this case, the patient argued that the board had exceeded its jurisdiction in authorizing ECT because ECT fell within the definition of psychosurgery in the Ontario MHA. This paper reviews the legal issues involved and summarizes the most substantive evidence presented for and against any causal association between ECT and demonstrable brain damage. The judicial decision upholding the treatment order is discussed.     

Safety and efficacy of combined upper blepharoplasties and open Coronal Browlift: A consecutive series of 600 patients

Surgical rejuvenation of the upper face involves the correction of excess and lax forehead, eyelid, and periorbital skin. Improving the appearance by correcting the effects of aging involves a combination of blepharoplasty and open coronal foreheadplasty. Many surgeons and several reports question the safety of both procedures being performed concomitantly. The difficulty arises in precisely balancing the skin excision from the frontal forehead and upper eyelid areas. Over-resection of skin may result in incomplete closure of the eyelid and dry-eye syndrome, while an inadequate resection may produce a poor aesthetic result. There is no large series that documents the safety and effectiveness of these two procedures being performed concomitantly. Furthermore, with the recent and rapid development of complex multiplanar endoscopic facial rejuvenation techniques, the basic open forehead-plasty has become increasingly overlooked as a legitimate, efficacious technique for rejuvenation of the upper face. The technique utilized in this series is presented in detail. The consistently excellent results obtained satisfy the aesthetic goals of patients as well as the goals of surgeons, and suggest a renewed interest in the technique based upon its simplicity and easily reproducible results.     

Sympathetic overactivity in patients with chronic renal failure.

BACKGROUND: Hypertension is a frequent complication of chronic renal failure, but its causes are not fully understood. There is indirect evidence that increased activity of the sympathetic nervous system might contribute to hypertension in patients with end-stage renal disease, but sympathetic-nerve discharge has not been measured directly in patients or animals with chronic renal failure. METHODS: We recorded the rate of postganglionic sympathetic-nerve discharge to the blood vessels in skeletal muscle by means of microelectrodes inserted into the peroneal nerve in 18 patients with native kidneys who were undergoing long-term treatment with hemodialysis (of whom 14 had hypertension), 5 patients receiving hemodialysis who had undergone bilateral nephrectomy (of whom 1 had hypertension), and 11 normal subjects. RESULTS. The mean (+/- SE) rate of sympathetic-nerve discharge was 2.5 times higher in the patients receiving hemodialysis who had not undergone nephrectomy than in the normal subjects (58 +/- 3 vs. 23 +/- 3 bursts per minute, P < 0.01). In contrast, the rate of sympathetic-nerve discharge was similar in the patients receiving hemodialysis who had undergone bilateral nephrectomy (21 +/- 6 bursts per minute) and the normal subjects. The rate of sympathetic-nerve discharge in the patients receiving hemodialysis who had not undergone nephrectomy was also significantly higher (P < 0.01) than that in the patients with bilateral nephrectomy, and it was accompanied in the former group by higher values for vascular resistance in the calf (45 +/- 4 vs. 22 +/- 4 units, P < 0.05) and mean arterial pressure (106 +/- 4 vs. 76 +/- 14 mm Hg, P < 0.05). The rate of sympathetic-nerve discharge was not correlated with either plasma norepinephrine concentrations or plasma renin activity. CONCLUSIONS: Chronic renal failure may be accompanied by reversible sympathetic activation, which appears to be mediated by an afferent signal arising in the failing kidneys.     

Gluthatione-S-transferase P1 polymorphism I105V in familial and sporadic prostate cancer

Several reports suggest that the glutathione-S-transferase (GST) family of enzymes is involved in a variety of cancers, due to their carcinogen-detoxification properties. A polymorphism in codon 105 of the pi variant (GSTP1 I105V), which affects the enzymatic activity of the enzyme, has been linked to the incidence of cancers from different organs. However, the published data in prostate cancer (PCa) is controversial. Some studies report an association with the GSTP1 I105V polymorphism and sporadic PCa, whereas other studies report no association. Recently, one study showed a positive correlation between the GSTP1 I105V polymorphism and familial PCa in a Japanese population. In the present study, we assessed the correlation of the GSTP1 I105V polymorphism with familial and sporadic PCa in an American population. We analyzed DNA samples from 438 patients with familial PCa, 499 patients with sporadic PCa, and 510 controls. We found no significant association between the GSTP1 I105V polymorphism and familial or sporadic PCa when compared to the control group [odds ratio (OR) =1.0 (0.74-1.37); P=0.58]. Moreover, no association was found after stratification for age of diagnosis, Gleason grade, or lymph node involvement [OR =0.84 (0.65-1.09), P=0.37]. These data indicate that there is no associated risk for sporadic or familial PCa in American families containing the GSTP1 I105V polymorphism.     

Partial trisomy 12 in a mentally retarded boy and translocation (12;21) in his mother

Cytogenetic studies of an infant with malformations and a peculiar appearance showed a partial trisomy of chromosome 12. The mother carried a translocation of the distal part of chromosome 12 onto the short arm of chromosome 21, with breakpoints most likely at 12q24 and 21p11.
