Effectiveness of rubber band ligation in haemorrhoids and factors related to relapse.

PURPOSE: to assess the effectiveness of ambulatory rubber band ligation (RBL) in the treatment of symptomatic internal haemorrhoids and to identify factors related to relapse. PATIENTS AND METHODS: prospective study of 232 patients treated with rubber band ligation for symptomatic haemorrhoids (grade I-III or grade IV with severe contraindication for surgery) from November 1996 to November 2000 at the outpatient clinic. Ligation was performed with a Stille AB (Comedic) ligator and suction pump, placing 1-3 bands per session and with up to three sessions per patient. Effectiveness of treatment was defined as the absence of symptoms and was confirmed by anoscopy by checking the residual scar after the cushions' detachment. Categorical variables were compared using the shi-squared test, whereas Student's t-test was used for continuous variables. Logistic regression was employed to identify clinical factors related to relapse. RESULTS: a total of 331 bands were placed during 235 sessions in the 163 patients who completed follow-up (70%). Mean age was 45.6 years, with males accounting for 64.4%. Most patients (86.5%) had grade II or grade III haemorrhoids. Overall morbidity was 6%. The most frequent complications were rectal tenesmus (11%), slight or mild anal pain (7.4%), dysuria (4.3%) and transient anal bleeding (3.7%). The treatment was effective in 86% of patients after a mean follow-up of 32 months. Efficacy was high for grades I and II (100% and 97.4% ) but decreased for grade III (69.8%; p<0.001) and grade IV (0%; p<0.001). Most relapses occurred within the first 24 months (87%) and were not significantly related to age, gender, duration of symptoms, itching, bleeding, pain, tenesmus or bowel habit, but were significantly related to the presence of prolapse and its grade (p<0.001), and to the involvement of left posterior, right lateral and anterior pedicles (p<0.05). CONCLUSIONS: ambulatory RBL is a safe and effective treatment for grade I, II and III symptomatic haemorrhoids, and is associated with low morbidity. Recurrence is uncommon and occurs mainly within the first 24 months, being related to the presence and grade of prolapse as well as to its location, but bears little relation to the rest of factors analysed.     

Splenic trauma. Conservative treatment

The spleen performs a wide range of important life functional at an hematological, immunological and hormonal level. The frequency of immediate and late complications following splenectomy suggest that the most conservative treatment possible must be adopted in cases of splenic trauma. The paper reports 180 cases observed during the period from January 1982 to August 1987. Conservative treatment was used to treat 92 patients. The real advantages of this methods are reviewed in relation to the stability of clinical conditions, the absence of associated abdominal lesions, and the availability of diagnostic equipment and intensive therapy units.     

McArdle disease: report of four brothers with myophosphorylase deficiency

Myophosphorylase deficiency, or McArdle disease, is an uncommon entity. The gene for human myophosphorylase has been cloned and is located on chromosome 11, in keeping with the autosomal recessive nature of the disease and there is an excess of male patients. The diagnosis is established by documentation of elevated glycogen content and reduced phosphorylase activity in biopsied muscle tissue. We report four cases with McArdle disease which were 16, 15, 11 and 5 years old. They were brothers, and they came to the hospital because of pain, cramps and myoglobinuria after exercise or infection; in the first case, a male patient, myoglobinuria caused acute renal failure. Three of them showed reduced phosphorylase activity in biopsied muscle tissue. We discuss the different therapeutic possibilities.     

Menière's disease: diagnostic criteria,criteria to establish stages,and standards for treatment evaluation. Bibliographic review and update

If all doctors would use the same concepts to define Meniere's Disease (MD) and the same scale to either establish the different steps of the disease or to evaluate a specific treatment, it would be easy to compare our results. This would be beneficial for patients because of the possibility of giving them a more accurate information about the follow-up of their disease and the advantages of the different possibilities of treatment. Since the introduction of informatic systems a new goal appeared: large databases could be achieved, as a result of being able to gather the different database that are independently used in each hospital, provided that rules to establish data would be previously standardized. The purpose of this paper is to evaluate the proposal of the Committee on Hearing and Equilibrium of the American Academy of Otolaryngology and those proposed by other authors according to the stated courses of action.     

One-year outcome after therapy with tissue plasminogen activator: report from the Thrombolysis and Angioplasty in Myocardial Infarction trial

To evaluate the long-term effects of reperfusion with tissue plasminogen activator (t-PA) and an aggressive strategy of revascularization with angioplasty and coronary artery bypass grafting, we obtained 1-year follow-up results from 386 consecutive patients enrolled in the Thrombolysis and Angioplasty in Myocardial Infarction (TAMI I) trial. All patients were treated with 100 to 150 mg of t-PA intravenously over 6 to 8 hours, and coronary angiography was performed within 90 minutes of initiation of therapy. In 197 patients with suitable anatomic characteristics, angioplasty was either performed immediately or was deferred for 7 to 10 days on a randomized basis. The remainder of the patients were treated as considered clinically appropriate. The in-hospital mortality rate was 7%, and only 1.9% of patients died in the first year after discharge from the hospital; three patients died of cardiac events and four died of noncardiac causes. Ninety-four percent of patients discharged alive from the hospital remained alive and had no myocardial infarctions during the first 12 posthospital months. Revascularization procedures after discharge from the hospital included angioplasty in 8% of patients and coronary artery bypass grafting in 5%. The high survival rates were evident in high-risk groups defined by age, ejection fraction, and extent of coronary artery disease. At 1-year follow-up 64% of patients less than 65 years of age were employed and only 10% reported that they were disabled; 94% of patients were in Canadian Heart Association class I or II. These low rates of follow-up events suggest a change in the "natural history" of the first year after acute myocardial infarction.
