ABSTRACT

This study investigated predictive risk factors of condylar remodeling changes after counterclockwise maxillomandibular advancement (CCW-MMA) and disc repositioning surgery. Forty-one female patients (75 condyles) treated with CCW-MMA and disc repositioning had cone beam computed tomography (CBCT) scans taken pre-surgery, immediately after surgery, and at an average 16 months post-surgery. Pre- and post-surgical three-dimensional models were superimposed using automated voxel-based registration on the cranial base to evaluate condylar displacements after surgery. Regional registration was performed to assess condylar remodeling in the follow-up period. Three-dimensional cephalometrics, shape correspondence (SPHARM-PDM), and volume measurements were applied to quantify changes. Pearson product-moment correlations and multiple regression analysis were performed. Highly statistically significant correlation showed that older patients were more susceptible to overall condylar volume reduction following CCW-MMA and disc repositioning (P≤0.001). Weak but statistically significant correlations were observed between condylar remodeling changes in the follow-up period and pre-surgical facial characteristics, magnitude of the surgical procedure, and condylar displacement changes. After CCW-MMA and disc repositioning, the condyles moved mostly downwards and medially, and were rotated medially and counterclockwise; displacements in the opposite direction were correlated with a greater risk of condylar resorption. Moreover, positional changes with surgery were only weakly associated with remodeling in the follow-up period, suggesting that other risk factors may play a role in condylar resorption.

ABSTRACT

The aim of this study was to investigate the incidence and risk factors for handball injuries in Brazilian elite handball players. Overall, 339 athletes from 21 handball teams who participated in the two main Brazilian championships were followed up during a season. In total, 312 injuries were reported by 201 athletes. The injury incidence rate during training was 3.7/1000 h, and during matches was 20.3/1000 matches. Ankle (19.4%, n = 46) and knee (13.5%, n = 32) were the body regions most affected by traumatic injuries. Shoulders (44.0%, n = 33) and knee (26.7%, n = 20) were the body regions most affected by overuse injuries. Muscle injuries (27.1%, n = 68) was the traumatic injury type most reported. Tendinopathy (91.8%, n = 56) was the overuse injury type most observed. Previous injury (OR: 2.42, CI 95%: 1.51-3.89) and an additional match per week (OR: 1.31, CI 95%: 1.05-1.62) were associated with a higher risk of overuse injury. Female athletes (OR: 1.56, CI 95%: 1.08-2.25) and an additional hour of training per week (OR: 1.09, CI 95%: 1.02-1.15) were associated with a higher risk of traumatic injury. This study showed that athletes with previous injury have shown a high risk of developing an overuse injury.

ABSTRACT

OBJECTIVES: To investigate the 3D morphological variations in 169 temporomandibular ioint (TMJ) condyles, using novel imaging statistical modeling approaches. SETTING AND SAMPLE POPULATION: The Department of Orthodontics and Pediatric Dentistry at the University of Michigan. Cone beam CT scans were acquired from 69 subjects with long-term TMJ osteoarthritis (OA, mean age 39.1±15.7 years), 15 subjects at initial consult diagnosis of OA (mean age 44.9±14.8 years), and seven healthy controls (mean age 43±12.4 years). MATERIALS AND METHODS: 3D surface models of the condyles were constructed, and homologous correspondent points on each model were established. The statistical framework included Direction-Projection-Permutation (DiProPerm) for testing statistical significance of the differences between healthy controls and the OA groups determined by clinical and radiographic diagnoses. RESULTS: Condylar morphology in OA and healthy subjects varied widely with categorization from mild to severe bone degeneration or overgrowth. DiProPerm statistics supported a significant difference between the healthy control group and the initial diagnosis of OA group (t=6.6, empirical p-value=0.006) and between healthy and long-term diagnosis of OA group (t=7.2, empirical p-value=0). Compared with healthy controls, the average condyle in OA subjects was significantly smaller in all dimensions, except its anterior surface, even in subjects with initial diagnosis of OA. CONCLUSION: This new statistical modeling of condylar morphology allows the development of more targeted classifications of this condition than previously possible.

ABSTRACT

The essential oils extracted from leaves of the Southern Brazilian native species Drimys angustifolia Miers (DA) and Drimys brasiliensis Miers (DB) by Clevenger distillation were analyzed by gas chromatography/mass spectrometry (GC/MS). The oils of DA and DB consisted predominantly of monoterpenoids and sesquiterpenoids. The largest components of DA oil were bicyclogermacrene (19.6%), sabinene (9.7%)and myrcene (5.2%), while DB oil was characterized by cyclocolorenone (18.2%), followed by terpinen-4-ol (8.7%) and alpha-gurjunene (6.9%). Laboratory tests were carried out to determine the repellency of the essential oils to the drywood termite Cryptotermes brevis (Isoptera: Kalotermitidae). It was observed that the oil showed repellency at the concentrations 25, 12.5, and 6.25 μg/mL. The oils of both species exhibited a negative repellency index, which represents repellent activity, except for DA oil at the highest concentration, which was attractive. Five deaths (11% of the termitesample) were observed at 25 μg/mL DA, in the fourhour repellency test, while four deaths occurred at 12.5 μg/mL (approximately 9%). The essential oil of DB did not cause any termite deaths...


Os óleos essenciais obtidos das folhas das árvores nativas do sul do Brasil Drimys angustifolia Miers (DA)e Drimys brasiliensis Miers (DB) foram analisados por cromatografia gasosa acoplada a espectrometria de massas (CG/EM). O óleo de DA foi caracterizado pela presença de monoterpenóides e sesquiterpenóides, biciclogermacreno (19,6%), seguido por sabineno (9,7%) e mirceno (5,2%). O óleo de DB foi caracterizado por sesquiterpenóides e monoterpenóides, ciclocolorenona (18,2%), seguido por terpinen-4-ol (8,7%) e alfagurjuneno(6,9%). Os testes foram realizados a fim de se determinar o potencial repelente dos óleos essenciais contra o cupim de madeira seca Cryptotermes brevis (Isoptera: Kalotermitidae) nas doses de 25, 12,5, e 6,25 μg/mL. Ambas as espécies mostraram índice de repelência negativo, o que representa a ocorrência da atividade repelente, exceto na maior concentração de DA, na qual o óleo mostrou-se atraente. Cinco mortes foram observadas na concentração de 25 μg/mL de DA, correspondendo a 11% do total em quatro horas de análise, sendo que 9% ocorreram na concentração de 12,5 μg/mL. No caso do óleo essencial de DB não foram observadas mortes de cupins...

ABSTRACT

BACKGROUND: Split liver transplantation (SLT) increases organ supply for hepatic transplantation. Long-term patient survival and complication rates seem to be equivalent between orthotopic liver transplantation (OLT) and SLT. There are controversies among transplant physicians due to an ethical dilemma between benefiting individual needs or those of society. Barshes and Goss (Am J Transplant 5:2047, 2005) demonstrated that the majority of adult liver transplant candidates are favorable to SLT. The aim of our study was to evaluate the opinions of patients at a Brazilian university hospital regarding SLT. MATERIALS AND METHODS: A questionnaire with 14 questions was applied to 50 patients included in a hepatic transplant waiting list regarding SLT. RESULTS: The overall attitudes of 66% of the participants were classified as utilitarian, 31% were classified as self-preserving, and 3% were undecided. Ninety-one percent of patients would be willing to share even if their expected survival after SLT was shorter than that with OLT. For 77% of patients, children must have priority over adults. However, 83% were unaware of the donors for pediatric transplantations. CONCLUSIONS: SLT is a consistent solution for organ demand despite controversies among transplant physicians. The present study demonstrated that most patients were favorable to SLT. In conclusion, attitudes toward graft sharing are not barriers to SLT.

ABSTRACT

Cytomegalovirus (CMV) disease is a major cause of morbidity and mortality in solid organ transplantation. Disseminated toxoplasmosis after liver transplantation is a rare but fatal event. Serologic screening of the donor and the recipient is essential to prophylactic management, early diagnosis and therapeutic strategies to minimize the consequences of these infections. The aim of the present study was to determine the seroprevalence of CMV and Toxoplasma gondii (TG) in a Brazilian liver transplant waiting list (LTWL). Serological data were collected from 44 candidates on the LTWL between May 2003 and November 2004. Serological investigation of antibodies IgM and IgG against CMV (anti-CMV) and TG (anti-T. gondii) was performed using fluorometry commercial kits. IgG anti-CMV was positive in 37 patients (94.9 percent) out of 39 available results. There were not IgM anti-CMV positive results. Out of 36 analyzed patients, 22 (61.1 percent) presented positive IgG anti-T. gondii and none had positive IgM anti-T. gondii. The high CMV seroprevalence among our LTWL reinforces the need for appropriate protocols to avoid related complications, like reactivation and superinfection by CMV. Environmental and drug prophylactic strategies against primary infection and reactivation, as well as early diagnosis and treatment of toxoplasmosis complications, are essential for the good outcome of transplant patients.

ABSTRACT

UNLABELLED: Chronic viral hepatitis is currently the most common indication for liver transplantation (OLT). Knowing the serological profile of patients on the liver transplant waiting list (LTWL) is essential to manage prophylactic and therapeutic strategies pre- and post-OLT. The aim of this study was to determine the hepatitis B virus (HBV) and hepatitis C virus (HCV) serological profile on the LTWL. METHODS: Serological data were collected from 44 candidates included on the LTWL from May 2003 to November 2004. HBV and HCV serological profiles were performed by microenzyme immunoassay. RESULTS: Twenty-eight patients (66.7%) lacked HBV serological markers. Anti-HBs was detected in 9.5% and was positive for HBsAg, anti-HBc, IgM anti-HBc, or HbeAg in 4.8% of patients, probably related to reactivation of chronic infection. In 7.1% of patients, the markers demonstrated serological cure of infection. In HCV patients, 41.5% were positive. There was HBV and HCV co-infection in 12.2% of patients. CONCLUSION: HBV infection in 21.4% of the patients corroborates the need to use more efficient protocols for prophylactic and therapeutic management pre- and post-OLT. The high prevalence of HCV infection reinforces the need to follow adequate protocols to avoid related complications and guarantee rational and universal use of more efficient drugs.

ABSTRACT

A study of HIV-related risk behavior was carried out in 1998 among Brazilian military conscripts aged 17-20 years. A sample of 30,318 subjects was selected in three strata, pertaining to counties from: 1) the North and Central-West (N/CW); 2) South (S); and the states of Rio de Janeiro and São Paulo. HIV prevalence rates were estimated in all strata. The objective of this paper was to analyze the results according to differences in socioeconomic status (SES). The statistical analysis used an index of sexual risk behavior and logistic regression models. The N/CW stratum showed the worst indicators for SES, sexual risk behavior, and sexually transmitted infections (STIs), as well as the highest HIV seroprevalence rate. The best indicators for all variables were found in the RJ/SP stratum. The South showed intermediate results. Level of schooling also played a relevant role. In all three strata the conscripts with an incomplete high school education displayed the worst sexual risk behavior index, shown to be a relevant predictor of STI-related problems, including HIV infection.

ABSTRACT

Many athletes and active people have consumed a large variety of supplements in order to get a good shape or a better performance in competitions. Due to this, several studies have been carried out to determine if these supplements are in fact ergogenic aids. Creatine seems to be related to the performance enhance in high intensity intermittent exercises. Carnitine might probably improve the aerobic capacity by stimulating lipid oxidation on muscle cells during long term exercise. Bicarbonate is thought to increase blood pH delaying the onset of peripheral fatigue in high intensity exercises of short duration and strength training. Some other supplements like branched-chain amino acids and chromium are also involved in body composition changes as a gain of fat free mass and loss of fat mass. The effects caused by these supplements during physical activity have not been fully described in literature yet as well as their side effects.

ABSTRACT

RATIONALE AND OBJECTIVES: The purpose of this study was to examine the effects of placing a metal stent across a bronchial orifice. MATERIALS AND METHODS: Nine pigs were used as test subjects, because the right upper lobe bronchus comes directly off the trachea in these animals. One of three types of metal stents was placed into the trachea of each pig and covered the orifice of the right upper lobe bronchus. Follow-up studies were performed at 1 and 3 months to evaluate the right upper lobe for signs of bronchial obstruction, infection, and atelectasis. The animals were sacrificed at 3 months to study the histopathologic changes of the trachea and lungs. RESULTS: Two upper lobe bronchi remained patent; seven were obstructed by granulation tissue or plugs of mucus and inflammatory cells. Right upper lobe infiltration and atelectasis were seen in eight animals. Interestingly, radiographic opacities were also common in other lung segments. There was a tendency toward fewer and less extensive lung opacities at 3 months compared with that at 1 month. At histopathologic examination, areas of both acute and chronic pneumonia were found in the right upper lobe of all animals. The segment of trachea covered by the stent was lined with a thin layer of granulation tissue containing neutrophils, monocytes, and lymphocytes. The stent luminal surface was covered with columnar, cuboidal, and stratified squamous epithelium. Tracheal stenosis was seen in three animals because of excessive granulation tissue in two and a collapsed stent in one. CONCLUSION: Placement of metal stents in pig trachea covering the orifice of the right upper lobe bronchus resulted in retention of secretions and secondary infection in the right upper lobe and other distant lung segments.

ABSTRACT

OBJECTIVE: The aim of this study is to assess the validity of videothoracoscopy in the treatment of chronic pericardial effusions. STUDY PATIENTS: We studied 13 consecutive patients with chronic pericardial effusions and an indication for surgical treatment. The patients, 10 female and 3 male, had a mean age of 48 years (21-72 years). Eleven patients had recurrent pericardial effusion and two patients had anterior mediastinal masses of unknown etiology and a large pericardial effusion. METHODS: A videothoracoscopy was performed in every patient, under general anesthesia with a double-lumen endotracheal tube. The thoracic cavity was inspected, the pericardial effusion was drained and a partial pericardectomy was performed. RESULTS: There was no postoperative mortality or morbidity. Average duration of postoperative thoracic drain and postoperative stay were, 1.2 and 2.4 days respectively. Follow-up ranged from 1 to 48 months (mean 23.3 months). One patient died due to progression of his malignant disease. There were no cases of recurrent pericardial effusions. CONCLUSIONS: Video assisted pericardectomy is a safe technique that should be considered in the treatment of chronic pericardial effusions.

ABSTRACT

Left atrial myxoma remains a diagnostic challenge. The authors briefly review previously reported cases and their individualistic clinical and laboratory features. This report documents an unusual clinical presentation, initially directing attention to the central nervous system as well as bilateral tenderness and weakness of the extremities. The illness was considered to be a vasculitis until thirty-one months later when the diagnosis of left atrial myxoma was made. The tumor was successfully removed.

ABSTRACT

A 52-year-old man with a symptomatic condition-a huge left coronary artery fistula simulating a cor triatriatum sinister on transthoracic echocardiography-was referred to our center for surgery. Coronary angiography unequivocally established the diagnosis of a left coronary artery fistula and contrast opacification of the right atrium was observed. However, as a result of the size of the fistula, the entry site could not be defined with certainty. A transesophageal echocardiography (TEE) was then performed, and the opening site was clearly identified in the postero-lateral wall of the right atrium. After the surgical treatment transesophageal echocardiography was repeated, and it was confirmed that the surgical treatment had succeeded.

ABSTRACT

We report the case of a patient with complete heart block caused by extension of a congenital aneurysm of the sinus of Valsalva into the upper interventricular septum, which was diagnosed by transthoracic and transesophageal echocardiography. We emphasize the rarity of this pathology and the value of transesophageal echocardiography in its assessment, providing a complete anatomicofunctional characterization and allowing surgical repair without previous cardiac catheterization.

ABSTRACT

In this study the authors make a critical appraisal of transesophageal echocardiography. A retrospective analysis was made of the transesophageal echocardiographic performed in the Thoracic Surgery Center of S. João Hospital, Oporto, over a period of approximately five years. The authors report the limitations and complications of this diagnostic tool with particular emphasis on the leading causes of pitfalls. Between October 1990 and December 1995, 1282 examinations were performed in our echocardiographic laboratory, mean age 49.6 +/- 14 years (5-86), 57% of the patients were female and 43% male. A biplane transducer was used in these examinations. Patient absenteeism was 2% and only one major complication occurred in a patient with an aortic dissection. Pitfalls are of special concern with this technology. The new esophagic window over the heart and the high quality of the cardiac images, depicting structures and anatomic details inaccessible, or difficult to be observed by transthoracic echocardiographic, led to the major causes of transesophageal echocardiographic pitfalls. Once recognized, most of the pitfalls can be avoided. In what concerns our experience, examples of the most common pitfalls are illustrated.

ABSTRACT

Between August 1992 and July 1995 five patients with cardiac free wall rupture after acute myocardial infarction underwent surgical treatment in Centro de Cirurgia Torácica do Hospital de S. João. The diagnosis was suggested by the hemodynamic changes and in four patients confirmed with echocardiography and pericardiocentesis. All patients survived and were discharged from the hospital. Medical treatment with inotropic drugs, pericardiocentesis and intraaortic balloon counterpulsation allows hemodynamic stabilization but only early surgery may assure survival.
