Kommerell Diverticulum: Right Aortic Arch with Anomalous Origin of Left Subclavian Artery and Duplicity of Right Vertebral Artery in a 16-Year-Old Girl.

BACKGROUND Kommerell diverticulum with a right-sided aortic arch is a rare congenital anatomical condition most often observed in adults. A possible etiology of the subclavian artery's anomalous origin would be an abnormality in regression of the fourth primitive aortic arch during embryonic development. CASE REPORT We report on the case of a 16-year-old female patient presenting with complaints of occasional tachycardia and mild non-specific dyspnea after anxiety crises. Physical examination revealed lower amplitude of the pulses in the left upper limb compared to the right upper limb, and difference in blood pressure (BP) values of 80×60 mmHg, and 100×60 mmHg, respectively. Different radiological imaging modalities were performed to elucidate a possible vascular abnormality. Multislice detector computed tomography angiography of the thoracic aorta and supra-aortic trunks showed a right-sided aortic arch and an aberrant origin of the left subclavian artery with a retroesophageal course and dilation of its emergence (Kommerell diverticulum), as well as duplicity of the right vertebral artery (RVA). Considering the actual small diameter of the diverticulum and the absence of dysphagia or severe external esophageal compression analyzed by the esophagogram, vascular surgery was not indicated. Since complications have been described in the literature, the patient must be kept under observation in the future. CONCLUSIONS Congenital vascular alterations, including Kommerell diverticulum with right-sided aortic arch and the aberrant origin of the left subclavian artery, should be suspected in otherwise asymptomatic young patients with few clinical manifestations. Investigation with different imaging methods helps to clarify the vascular abnormalities, to support a possible surgical procedure indication, and to monitor the patients in follow-up.

Comparison of myocardial T1 and T2 values in 3 T with T2* in 1.5 T in patients with iron overload and controls.

Myocardial iron quantification remains limited to 1.5 T systems with T2* measurement. The present study aimed at comparing myocardial T2* values at 1.5 T to T1 and T2 mapping at 3.0 T in patients with iron overload and healthy controls. A total of 17 normal volunteers and seven patients with a history of myocardial iron overload were prospectively enrolled. Mid-interventricular septum T2*, native T1 and T2 times were quantified on the same day, using a multi-echo gradient-echo sequence at 1.5 T and T1 and T2 mapping sequences at 3.0 T, respectively. Subjects with myocardial iron overload (T2* < 20 ms) in comparison with those without had significantly lower mean myocardial T1 times (868.9 ± 120.2 vs. 1170.3 ± 25.0 ms P = 0.005 respectively) and T2 times (34.9 ± 4.7 vs. 45.1 ± 2.0 ms P = 0.007 respectively). 3 T T1 and T2 times strongly correlated with 1.5 T, T2* times (Pearson's r = 0.95 and 0.91 respectively). T1 and T2 measures presented less variability than T2* in inter- and intra-observer analysis. Native myocardial T1 and T2 times at 3 T correlate closely with T2* times at 1.5 T and may be useful for myocardial iron overload quantification.

Gonadotropin and Estradiol Levels after Leuprolide Stimulation Tests in Brazilian Girls with Precocious Puberty.

STUDY OBJECTIVE: To determine the best cutoff value on the leuprolide stimulation test for the diagnosis of central precocious puberty (CPP) in a Brazilian population. DESIGN, SETTING, AND PARTICIPANTS: This observational study included 60 girls with CPP, as shown on the basis of serum concentrations of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) before and 3 hours after subcutaneous administration of 500 µg leuprolide acetate and by measuring serum estradiol concentrations 24 hours later. Six months later, each subject was clinically evaluated to determine whether she had experienced progressive or nonprogressive puberty. MAIN OUTCOME MEASURES: Analyzing the best cutoff for LH after subcutaneous administration of 500 µg leuprolide acetate. RESULTS: The best cutoff was a 3-hour LH level of greater than 4.0 mIU/mL, providing the highest sensitivity (73%) and specificity (83.1%), whereas a 3-hour LH level greater than 8.4 mIU/mL had a specificity of 100%. A 24-hour E2 concentration greater than 52.9 pg/mL had a sensitivity of 68% and a specificity of 74%. There was no association between pubertal development and disease progression. Signs such as thelarche and pubarche did not determine the evolution of the disease (P = .17). Clinical condition was associated with bone age/chronological age (P = .01), basal LH (P < .01), 3-hour LH (P = .02), baseline LH/FSH indices (P < .01) and after 3 hours (P < .01), and E2 at 24 hours (P = .02). CONCLUSION: The optimal parameter indicating hypothalamic-pituitary-gonadal axis activation in our sample was a 3-hour LH level greater than 4.0 mIU/mL. A diagnosis of CPP, however, should be based on a set of criteria and not on an isolated measurement, because typical laboratory findings associated with CPP may not be present in all patients.

Hipertensão arterial pulmonar: uso do realce tardio miocárdico pela ressonância magnética cardíaca na avaliação de risco / Pulmonary arterial hypertension: use of delayed contrast-enhanced cardiovascular magnetic resonance in risk assessment

FUNDAMENTO: A hipertensão arterial pulmonar é uma doença grave e progressiva. O maior desafio clínico é seu diagnóstico precoce. OBJETIVO: Avaliar a presença e a extensão do realce tardio miocárdico pela ressonância magnética cardíaca bem como verificar se o percentual da massa de fibrose miocárdica é indicador de gravidade. MÉTODOS: Estudo transversal com 30 pacientes com hipertensão arterial pulmonar dos grupos I e IV, submetidos às avaliações clínica, funcional e hemodinâmica, e à ressonância magnética cardíaca. RESULTADOS: A média de idade dos pacientes foi de 52 anos, com predomínio do gênero feminino (77%). Dentre os pacientes, 53% apresentavam insuficiência ventricular direita ao diagnóstico, e 90% encontravam-se em classe funcional II/III. A média do teste de caminhada de 6 minutos foi de 395 m. No estudo hemodinâmico com o cateterismo direito, a média da pressão arterial pulmonar foi de 53,3 mmHg, do índice cardíaco de 2,1 L/min.m², e a mediana da pressão atrial direita foi de 13,5 mmHg. Realce tardio do miocárdio pela ressonância magnética cardíaca foi encontrado em 28 pacientes. A mediana da massa de fibrose foi 9,9 g e do percentual da massa de fibrose de 6,17%. A presença de classe funcional IV, insuficiência ventricular direita ao diagnóstico, teste de caminhada de 6 minutos < 300 metros e pressão atrial direita > 15 mmHg, com índice cardíaco < 2,0 L/min.m², teve associação significativa com maior percentual de fibrose miocárdica. CONCLUSÃO: O percentual da massa de fibrose miocárdica mostra-se um marcador não invasivo com perspectivas promissoras na identificação do paciente portador de hipertensão pulmonar com fatores de alto risco.

BACKGROUND: Pulmonary arterial hypertension is a severe and progressive disease. Its early diagnosis is the greatest clinical challenge. OBJECTIVE: To evaluate the presence and extension of the delayed myocardial contrast-enhanced cardiovascular magnetic resonance, as well as to verify if the percentage of the myocardial fibrosis mass is a severity predictor. METHODS: Cross-sectional study with 30 patients with pulmonary arterial hypertension of groups I and IV, subjected to clinical, functional and hemodynamic evaluation, and to cardiac magnetic resonance. RESULTS: The mean age of patients was 52 years old, with female predominance (77%). Among the patients, 53% had right ventricular failure at diagnosis, and 90% were in functional class II/III. The mean of the 6-minute walk test was 395m. In hemodynamic study with right catheterism, the mean average pulmonary arterial pressure was 53.3mmHg, of the cardiac index of 2.1L/ min.m², and median right atrial pressure was 13.5 mmHg. Delayed myocardial contrast-enhanced cardiovascular magnetic resonance was found in 28 patients. The mean fibrosis mass was 9.9 g and the median percentage of fibrosis mass was 6.17%. The presence of functional class IV, right ventricular failure at diagnosis, 6-minute walk test < 300 meters and right atrial pressure > 15mmHg, with cardiac index < 2.0L/ min.m², there was a relevant association with the increased percentage of myocardial fibrosis. CONCLUSION: The percentage of the myocardial fibrosis mass indicates a non-invasive marker with promising perspectives in identifying patients with high risk factors for pulmonary hypertension.

Right and left ventricular function and myocardial scarring in adult patients with sickle cell disease: a comprehensive magnetic resonance assessment of hepatic and myocardial iron overload.

BACKGROUND: Patients with Sickle cell disease (SCD) who receive regular transfusions are at risk for developing cardiac toxicity from iron overload. The aim of this study was to assess right and left cardiac volumes and function, late gadolinium enhancement (LGE) and iron deposits in patients with SCD using CMR, correlating these values with transfusion burden, ferritin and hemoglobin levels. METHODS: Thirty patients with SCD older than 20 years of age were studied in a 1.5 T scanner and compared to age- and sex-matched normal controls. Patients underwent analysis of biventricular volumes and function, LGE and T2* assessment of the liver and heart. RESULTS: When compared to controls, patients with SCD presented higher left ventricular (LV) volumes with decreased ejection fraction (EF) with an increase in stroke volume (SV) and LV hypertrophy. The right ventricle (RV) also presented with a decreased EF and hypertrophy, with an increased end-systolic volume. Although twenty-six patients had increased liver iron concentrations (median liver iron concentration value was 11.83 ± 9.66 mg/g), only one patient demonstrated an abnormal heart T2* < 20 msec. Only four patients (13%) LGE, with only one patient with an ischemic pattern. CONCLUSIONS: Abnormal heart iron levels and myocardial scars are not a common finding in SCD despite increased liver iron overload. The significantly different ventricular function seen in SCD compared to normal suggests the changes in RV and LV function may not be due to the anemia alone. Future studies are necessary to confirm this association.

Ressonância magnética na síndrome da interseção do antebraço: ensaio iconográfico / Magnetic resonance imaging in intersection syndrome of the forearm: iconographic essay

A ressonância magnética tem papel importante na avaliação de pacientes com dor na face dorsal do antebraço distal e do punho. Entre as causas de dor destaca-se a síndrome da interseção, um processo inflamatório dos tendões do segundo compartimento extensor do antebraço (extensor radial curto do carpo e extensor radial longo do carpo), geralmente provocado por trauma local direto ou atividades repetitivas que exigem a flexão e extensão do punho. Nosso trabalho visa a ilustrar os achados típicos da síndrome da interseção do antebraço e discutir os principais diagnósticos diferenciais.

Magnetic resonance imaging plays a relevant role in the assessment of patients with pain on the dorsal aspect of the distal forearm and wrist. Among the causes of pain, intersection syndrome is highlighted, corresponding to an inflammatory process affecting the tendons of the second compartment of the forearm extensor (extensor carpi radialis brevis and extensor carpi radialis longus), usually caused by direct trauma or repetitive activities requiring wrist flexion and extension. The present essay is aimed at illustrating the typical findings in intersection syndrome of the forearm and discuss the main differential diagnoses.

Left and right ventricular function and volume assessment in young thalassemia major patients with no related myocardial iron overload.

Thalassemia major (TM) patients have altered ventricular volumes and ejection fraction compared to normals, although evidence for these findings stem from restricted patient groups and has never been reproduced. We sought to evaluate cardiac parameters by cardiovascular magnetic resonance (CMR) in a group of young TM patients not covered by previous studies that are more representative of the TM population in many countries. Seventy patients including 40 TM with normal myocardial iron concentrations, and 30 age- and gender-matched normal (NL) volunteers underwent a CMR study for assessment of left and right ventricle volumes and function using a 1.5-T scanner. Left and right ventricle ejection fraction, indexed systolic and diastolic volumes, and indexed mass were compared between the two groups. Mean age of TM patients was 18.2 ± 7.1 versus 17.5 ± 8.5 years in NL with no significant differences (P = 0.73). There was no difference in left ventricular (LV) ejection fraction between the groups (TM 64.9 ± 5.7 %, NL 64.9 ± 5.2 %; P = 0.97). LV normalized end-diastolic and end-systolic volumes were significantly higher in patients with TM compared to NL volunteers (76.8 ± 19.4 versus 66.6 ± 11.7 mL/m², P = 0.008, and 27.0 ± 8.8 versus 23.6 ± 5.0 mL/m², P = 0.045). LV indexed mass was also higher in TM patients compared to NL (51.2 ± 11.9 versus 42.0 ± 8.5 g/m², P < 0.001). No significant differences were observed in right ventricular parameters. In conclusion, younger patients with TM do not present different left or right ventricular function values compared to normal controls despite having increased left ventricular volumes and mass.

[Surgical and non-surgical treatment of vaginal agenesis: analysis of a series of cases]. / Tratamento cirúrgico e conservador da agenesia vaginal: análise de uma série de casos.

PURPOSE: This study aimed to evaluate the results of neovaginoplasty by a modified McIndoe-Bannister technique and by the non-surgical Frank technique. METHODS: This retrospective study was conducted on a convenience sample of 25 women with vaginal agenesis undergoing surgical or conservative treatment at an Infant-Pubertal Gynecology Outpatient Clinic. Data were obtained from the medical records. Fifteen women underwent the surgical McIndoe-Bannister modified technique Surgical Group, and 10 women underwent the non-surgical Frank technique Frank Group. The following parameters were considered for comparative analysis between the two samples: vaginometry, surgical and non-surgical complications, and sexual satisfaction after treatment. Sexual satisfaction was assessed by a simple question: How is your sex life? RESULTS: There were differences related to vaginal length before and after performing exercises in both Frank Group (initial vaginal length 2.4±2.0 cm versus 6.9±1.1 cm after treatment, p<0.0001) and Surgical Group (initial vaginal length 0.9±1.4 cm versus 8.0±0.8 cm after treatment, p<0.0001). Increased vaginal length was observed in Surgical Group compared to Frank Group (Frank Group=7.0±0.9 cm versus Surgical Group=8.0±0.8 cm, p=0.0005). Forty percent of Surgical Group women had surgical complications versus no complications with the Frank technique. All women reported to be satisfied with their sexual life. CONCLUSION: The present data indicate that both the surgical and Frank techniques are effective for the treatment of vaginal agenesis, resulting in the construction of a vagina that pewrmits sexual intercourse and sexual satisfaction. The favorable aspects of the Frank technique are related to its low cost and to the low rates of major complications.

Comportamento agregativo, preferência por sítio de repouso e variações diurnas de atividade em Bulimulus tenuissimus (d'Orbigny, 1835) (Mollusca, Bulimulidae) no Laboratório / Basic ethogram, aggregative behavior and preference for site rest in Bulimulus tenuissimus (d'Orbigny, 1835) (Mollusca, Bulimulidae) in laboratory conditions

O comportamento de moluscos terrestres é pouco estudado, apesar de representar uma ferramenta importante para a conservação ou controle desses animais. Desse modo, objetivou-se descrever o etograma básico de Bulimulus tenuissimus, verificar a ocorrência de comportamento agregativo e preferência por sítio de repouso. Para descrição do etograma, observaram-se grupos de 15 moluscos durante 24 horas, através do método de varredura a intervalos de 10 minutos. Para verificação do comportamento agregativo, outros 50 animais foram divididos em grupos de 10 e acondicionados em terrários plásticos previamente divididos em quadrantes. A agregação foi estabelecida pelo número de moluscos/quadrante, e a preferência por sítio de repouso, pelo número de moluscos em posições pré-determinadas. Confirmou-se o hábito noturno da espécie, sendo os atos comportamentais explorar e alimentar-se os mais frequentes. Não se observou a existência de comportamento agregativo, e a parede do terrário foi o sítio de repouso mais utilizado pelos moluscos.

MR imaging in deep pelvic endometriosis: a pictorial essay.

Deep pelvic endometriosis is an important gynecologic disorder that is responsible for severe pelvic pain and is defined as subperitoneal invasion that exceeds 5 mm in depth. Deep pelvic endometriosis can affect the retrocervical region, uterosacral ligaments, rectum, rectovaginal septum, vagina, urinary tract, and other extraperitoneal pelvic sites. It is commonly associated with dysmenorrhea, dyspareunia, pelvic pain, urinary tract symptoms, and infertility. Because surgery remains the best therapeutic option for affected patients, the accurate preoperative assessment of the extension of endometriotic disease is extremely important. Pelvic magnetic resonance (MR) imaging is a noninvasive method with high spatial resolution that allows multiplanar evaluation of deep pelvic endometriosis and good tissue characterization, but without the use of ionizing radiation or iodinated contrast agents. MR imaging yields important findings that help grade the disease and identify subperitoneal lesion extension and other associated disease entities, thereby facilitating accurate diagnosis and adequate treatment. Radiologists should be familiar with the MR imaging findings of deep infiltrating endometriosis in various anatomic locations so that they can provide information that allows adequate presurgical counseling.

Avaliação por ressonância magnética das fístulas perianais: ensaio iconográfico / Magnetic resonance imaging evaluation of perianal fistulas: iconographic essay

A fístula perianal é uma condição incomum com tendência a recorrência, que usualmente é decorrente de infecção prévia não observada à cirurgia. A ressonância magnética mostra com acurácia a anatomia da região e a relação da fístula com o diafragma pélvico e a fossa isquiorretal, classificando-a em cinco tipos. A ressonância magnética é superior a qualquer outra modalidade para a detecção de focos infecciosos na região perianal, incluindo a exploração cirúrgica. Tem a capacidade de guiar o procedimento cirúrgico, reduzindo a taxa de recorrência em 75 por cento em pacientes com doença complexa.

Fistula in ano is an uncommon condition that has a tendency to recur despite seemingly appropriate surgery. Recurrent fistula in ano is usually caused by infection that was missed during surgical exploration. Magnetic resonance imaging has been shown to accurately demonstrate the anatomy of the perianal region as well as the fistula's relationship with the pelvic diaphragm and ischiorectal fossa, allowing the classification of fistulas into five types. Magnetic resonance imaging depicts infectious foci in the perianal region better than any other investigation modality, including surgical exploration. Magnetic resonance image-guided surgery helps to reduce postoperative recurrence by 75 percent in patients with complex disease.

Sexual dysfunction treatment in a patient with müllerian agenesy submitted to neovaginoplasty: a case report.

Vagina agenesis is a rare entity. Mayer-Rokitansky-Kuster-Hauser syndrome is the most significant cause of vagina agenesis, whereas the second most common cause is complete androgen syndrome. Surgical treatment can propitiate a vaginal reconstruction, but sexual function depends on several factors that affect sexual performance. Many reports focus on the intraoperative and postoperative results and only describe the global approach to these patients, but reports focusing on the management of these patients to enable them to have a normal sexual life are lacking. This case report highlights a multidisciplinary treatment for this kind of morbidity and emphasizes the necessity of incorporating careful attention to sexual health in the treatment of these patients so that they may achieve a good therapeutic response, resulting in a pleasurable sexual life and a good quality of living.
