Preparation of the polidocanol foam according to Tessari technique immediately before application (so that the "microbubbles" of the foam did not disintegrate);
Application according to the Blanchard technique (Fig. 2) through a disposable transparent anoscope, with the patient in jackknife position, using a 20mL disposable syringe of the mixture (polidocanol + air) and a reusable 10 cm syringe extender adapted to an intravenous needle;
Patients treated in a maximum of 3 sessions at 3 weeks intervals;
Maximum dose per treatment session of 20mL of mixture of 4mL of polidocanol 3% with 16mL of air;
In each session more than one hemorrhoid cushion could be treated.

Use of reusable metal ligation device connected to a vacuum system (McGown suction method) to apply the rubber bands above the dentated line through a disposable transparent anoscope with the patient in jackknife position;
A maximum of 3 sessions of ligation at 3-week intervals were performed;
More than 1 band per session could be applied.

Hemorrhoids, Internal

Two distinct periods were considered: intervention and follow-up. During the intervention period patients were observed at 3-week intervals (minimum of 3 weeks and maximum of 9 weeks depending on the number of instrumental treatments performed). The required number of sessions of any of the office-based treatments (maximum of 3 sessions) was determined by clinical and anoscopy response (if after the treatment the participant scored zero points in the Sodergren scale or the anoscopy did not reveal significant hemorrhoidal disease, there was no place for additional instrumental therapy and the patient started the follow-up period.
If there was therapeutic failure at the end of the third session or if there was a significant complication (moderate or severe) the patient's participation in the study ended and he was referred for treatment with other type of office-based procedure or surgery.

Polidocanol Foam Versus Rubber Band Ligation in the Treatment of Hemorrhoidal Disease

Sclerotherapy With Polidocanol Foam Versus Rubber Band Ligation in the Treatment of First, Second and Third-Grade Hemorrhoidal Disease: a Randomized, Controlled Trial

Achievement of therapeutic success. Classified as:
Complete (Sodergren score = 0 and bleeding grade ≤ 1);
Partial (Sodergren score> 0 and bleeding grade > 1 but with improvement over initial score);
Therapeutic failure (participants that, at the end of three sessions of instrumental treatment, aggravated or maintained the initial Sodergren score and bleeding grade).

Recurrence of hemorrhoidal disease during the follow-up period (only for patients who have had some degree of therapeutic success). Classified as:
Mild (Sodergren score and bleeding grade higher than the evaluation at the beginning of the follow-up period but lower than the initial ones without the need for instrumental or surgical intervention);
Severe (Sodergren score and degree of hemorrhage ≥ the initial one requiring instrumental or surgical intervention).

Complications resulting from the office-based procedures are recorded and classified as:
Mild (e.g. pain/discomfort; pruritus; bright red blood on toilet paper/cleaning pad, hemorrhoidal thrombosis requiring only medical treatment);
Moderate (e.g. external hemorrhoidal thrombosis requiring surgical intervention; bright red blood that drips in the toilet or clot expulsion not requiring blood transfusion, urgent hemostasis or urgent surgery): obliges the participant to be withdrawn from the study but do not endanger the patient's life or leave long term sequelae;
Severe (e.g. sepsis; Fournier's gangrene; perineal abscess; bleeding with hemodynamic instability, transfusional need or urgent surgery; sexual impotence in man): obliges the participant to be withdrawn from the study and put the patient's life at risk or implies long-term sequelae.

Number of instrumental treatment sessions required to achieve therapeutic success.

Evolution of the grade of hemorrhoidal disease (Goligher's classification).

CHLOROQUINE FOR MAINTENANCE REMISSION OF AUTOIMMUNE HEPATITIS

DOUBLE-BLIND RANDOMIZED CLINICAL TRIAL WITH CHLOROQUINE VERSUS PLACEBO FOR MAINTENANCE OF REMISSION OF AUTOIMMUNE HEPATITIS

To evaluate the rate of recurrence of autoimmune hepatitis with histological remission after withdrawal of corticosteroids and immunosuppressive drugs and after introduction of maintenance therapy with chloroquine or placebo. Recurrence is defined by the sustained increase or progressive liver enzymes above twice the upper normal reference value (as defined by the criteria of the International Autoimmune Hepatitis) in at least two different dosages taken with an interval of 15 to 30 days.

To assess the occurrence of side effects of chloroquine and to evaluate if the use of chloroquine has a cost benefit for maintenance of remission histological, we will investigate hematological, dermatological, opthalmological, neurological, musculoeskeletal and gastrintestinal symptoms. To evaluate the ocular toxicity, patients will undergo ophthalmic evaluation to detect retinal deposits of chloroquine every six months. Other side effects will be assessed in each medical consultation from the speech of patients and clinical examination.If necessary exams will be performed to confirm the diagnosis (eg electromyography in cases of suspected peripheral neuropathy by chloroquine)
