Efficacy of the combination of water aerobics and metacognitive training on psychological and physical health variables and their relationship with SP1 and SP4 biomarkers in people with psychosis: a study protocol.

Background: Metacognitive Training (MCT) is widely used and effective in reducing positive symptoms in psychosis. Physical exercise, such as Water Aerobics (WA), improves general health, quality of life and symptoms as a low impact activity that allows social interactions. Preliminary results suggest a relationship between dopamine and psychotic symptoms, through SP transcription factors, SP1 and SP4 biomarkers.

Cuba's Role in International Atomic Energy Agency Regional Cooperation in Cardiology.

Cardiovascular diseases are the leading cause of death worldwide, and a health problem in low- and middle-income as well as high-income countries. They also constitute the main cause of death in Latin America, with ischemic heart disease as the principal cause in most countries of the region. In Cuba, heart disease is the first cause of death, followed by cancer and stroke.

Influence of plasma cleaning procedure on the interaction between soft tissue and abutments: a randomized controlled histologic study.

Introduction: Plasma application can lead to an improved adhesion between soft tissue and abutments and promotes cell spreading.

Objective: A triple-blinded randomized controlled clinical trial was performed to in vivo test the effect of cleaning abutment titanium surfaces with plasma of argon on cell adhesion and collagen fiber orientation at an early healing time.

Material And Methods: Thirty healthy patients with 30 submerged implants, at the second surgery, randomly received either a specially designed abutment with no additional treatment (as they come from industry; control group, G1) or cleaned by plasma of argon (test group, G2).

Immediate implants after the removal of maxillary impacted canines: a clinical series of nine patients.

Purpose: When impacted maxillary canines are not amenable to orthodontic traction or reimplantation, extraction is the only solution available, followed by the option of implant placement. The aim of this study was to present a surgical technique that allows placement of immediate implants following extraction of impacted maxillary canines.

Materials And Methods: Included in the study were patients with impacted maxillary canines who refused orthodontic treatment or transplantation and/or in whom the position of the canine teeth did not allow fenestration and orthodontic traction.

Purpose: To determine the survival of immediate dental implants with immediate loading in the partially edentulous mandible, by use of a full-arch screw-retained provisional restoration.

Materials And Methods: Patients who were partially edentulous in the mandible with indications for extraction of the remaining teeth and with a minimum follow-up of 12 months after implant placement were included in the study. They were treated in chronologic order by the insertion of 6 Defcon dental implants (Impladent, Sentmenat, Spain) subjected to immediate loading (4 interforaminal and 2 posterior placements).

Distance between periapical lesion and mandibular canal as a factor in periapical surgery in mandibular molars.

Purpose: Mandibular molars with a periapical pathology that remains unresolved by endodontic treatment may be considered for periapical surgery (PS); even for those situated in close proximity to the mandibular canal. Our objective was to compare PS in mandibular molars situated close to the mandibular canal, and those at a greater distance, and to study the postoperative morbidity and prognosis of both groups.

Patients And Methods: A follow-up study was made on PS carried out using the ultrasound technique.

Pain and swelling in periapical surgery. A literature update.

In recent years, periapical surgery (PS) has evolved thanks to the incorporation of technical and diagnostic advances. In PS, secondary effects such as pain and swelling occur as with all surgical procedures. The objective of the present study is to review the literature of articles published on pain and swelling during the postoperative period in periapical surgery.

Periapical surgery in maxillary premolars and molars: analysis in terms of the distance between the lesion and the maxillary sinus.

Purpose: This study compares periapical surgery (PS) of the maxillary premolars and molars in close proximity to the maxillary sinus with those not in close proximity, and assesses postoperative morbidity and prognosis.

Zygomatic bone graft for oral-antral communication closure and implant placement.

The roots of molar and premolar maxillary teeth are often very close to the floor of the maxillary sinus. As a result, extraction of these teeth can leave an oral-antral communication or lead to a fistula that requires treatment. A woman with an oral-antral communication secondary to extraction of a maxillary molar is presented.

Their treatment consisted of maxillary fixed prostheses supported by conventional implants placed in residual anatomic structures in conjunction with zygomatic implants positioned using the sinus slot technique of Stella and Warner.

Materials And Methods: A retrospective chart review was conducted of all patients who received zygomatic implants between January 2000 and January 2005.

Immediate maxillary lateral incisor implants with nonocclusal loading provisional crowns.

This clinical report series describes a treatment modality involving immediately placed dental implants in maxillary lateral incisor sites using noncemented immediate provisional crowns retained with calcinable copings (prosthetic complement used in preparing the metal for the definitive prosthesis). Ten implants were placed in eight patients for the replacement of maxillary lateral incisors: two immediate and eight corresponding to cases of agenesis. All were subjected to immediate rehabilitation with provisional acrylic resin crowns in nonocclusal loading.

Periapical surgery of maxillary posterior teeth. A review of the literature.

In recent years, periapical surgery has evolved thanks to new diagnostic and technical advances. A review is made of the literature on periapical surgery of the antral teeth, based on a Medline search and on the revision of Spanish dental journals in the period between 1974 and 2003. The anatomy of the maxillary sinus is discussed, along with the diagnosis of periapical lesions and the relation of the maxillary sinus to the antral teeth.

Pain and inflammation after periapical surgery in 60 patients.

Purpose: Periapical surgery is followed by manifestations such as pain and swelling, the magnitude of which depends on the degree of tissue damage produced. A study is made of pain and inflammation in the 7 days after periapical surgery and its relation to patient age, gender, smoking, oral hygiene, the location and number of teeth implicated, the duration of the operation, the type of incision and flap involved, and the extent of ostectomy.

Materials And Methods: Sixty patients (22 males, 38 females) with a mean age of 38.

Zygomatic implants using the sinus slot technique: clinical report of a patient series.

Purpose: The management of 5 patients with extreme maxillary atrophy and treatment consisting of maxillary fixed prostheses supported by conventional implants and zygomatic fixations positioned according to the sinus slot technique is reported.
