Clinical relevance linked to echocardiography diagnosis in Bland, White and Garland syndrome

Published on: 6th March, 2020

OCLC Number/Unique Identifier: 8560715071

Introduction: Bland, White and Garland syndrome is a coronary anomaly with high mortality without treatment. Its clinical presentation is varied which makes epidemiological documentation difficult. Echocardiography is a useful non-invasive tool for diagnosis. Objective: To determine the echocardiographic variables that lead to the diagnosis of Bland, White and Garland syndrome and their clinical relevance. Material: Observational, prospective and cross-sectional study in 31 patients of the “William Soler” Pediatric Cardiocenter, from 2005 to 2018. To check the association of echocardiographic variables with the diagnosis of Bland, White and Garland syndrome, an effectiveness study was carried out that included the analysis of the incidence of echocardiographic variables that lead to the diagnosis of this entity. The clinical relevance was estimated according to the minimum importance limit. The statistical validation of the research results adopted a significance level of less than 5% (p < 0.05). Results: The variables that facilitate the echocardiographic diagnosis of Bland, White and Garland syndrome were the echocardiographic visualization of the anomalous connection and the reversed flow in the anomalous left coronary artery. These echocardiographic measures have clinical relevance according to the quantification of risk estimators (incidence) the echocardiographic visualization of the anomalous connection, RR 39.00 and the reversed flow in the anomalous coronary artery, RR 26.31. LIM´s calculation value amounted to 6.31 and coincided with the risk estimators (incidence). Conclusion: The echocardiographic visualization of the anomalous origin of the left coronary artery from the pulmonary arterial trunk and the detection of the local intracoronary reversed flow instituted as factors to be considered for the effective diagnosis of the disease. The documentation of the diagnostic aspects of the syndrome through echocardiography contains high statistical value and clinical relevance.

Association between clinical forms of Leprosy and contacts with the vaccination state with BCG in five endemic municipalities in the Brazilian Amazon

Published on: 19th July, 2022

OCLC Number/Unique Identifier: 9575035083

Introduction: The World Health Organization (WHO) strategy for leprosy control from 2021 to 2030 focuses on interrupting transmission, reducing autochthonous cases to zero, and using a safe and effective vaccine and chemoprophylaxis. In 2020, 127,396 new cases were registered in the world, 19,195 new cases in the Americas, and, of these, 17,979 cases in Brazil, about 93.66% of the total in the Americas. Brazil is classified as a country with a high burden of the disease, occupying the 2nd place in the world, behind only India (WHO, 2020). Análise do período de 2010-2015 em publicação recente9, apresenta as seguintes cidades no estado do Pará nas quais se observou maiores taxas de incidência (detecção): Marituba, Belém, Marabá, Parauapebas e Altamira [9]. Material and method: This is an analytical retrospective study carried out in a database - Epi-Info resulting from records of Surveillance and Seroprevalence actions in five endemic municipalities for leprosy located in the Southeast and West of Pará. The following variables were analyzed: age, sex, Clinical Classification, vaccination status with BCG, and the result of the search for IgM antibodies against PGL-1 of Mycobacterium leprae by the “In house” ELISA technique. Results: We evaluated 1551 records examined in the laboratory from 2014 to 2016, which were classified into 123 Multibacillary -MB patients (123/1551 = 7.93%); 71 Paucibacillary-PB patients (71/1551 = 4.57%); 451 Intradomicilliary Consanguineous Contacts - CCOSI (451/1551 = 29.07%) and 906 Non Consanguineous Contacts - CNCOS (906/1551 = 58.41%). 57 MB patients (13.47%), 13 PB patients (3.07%), 133 CCOSI (31.44%) and 220 CNCOS (52.00%) were positive for PGL-1. The correlation of the Classification with the vaccination status showed 57 MB patients without any BCG (57/125 = 45.6%) and only 3 patients with two doses of BCG (3/125 = 2.4%); 17 PB patients without any dose of BCG (17/69 = 24.63%); 80 CCOSI without any BCG (80/455 = 17.58%) and 171 CNCOS (171/906 = 18.87%). The odds ratio (OR) in the analysis between unvaccinated MB patients compared to CCOSI was statistically significant (OR = 14.25; p ˂ 0.0001). The study shows the importance of using the BCG vaccine in healthy contacts of patients with leprosy, as it shows the probability of unvaccinated individuals being 14.25 times more likely to become ill with Multibacillary forms compared to CCOSI. In addition, the BCG vaccine has been in use for 80 years and is the only vaccine that we can use in leprosy control programs. Conclusion: Although the leprosy epidemiological data analyzed recently (2010 - 2015) show a downward trend in the main indicators in Pará, such as the detection of new cases and prevalence, the endemic municipalities are still classified as hyperendemic for the population under 15 years of age and This proves that Surveillance is essential, as well as BCG vaccination according to the Ministry of Health Standards.

Recurrence of atrial fibrillation after pulmonary vein isolation, should we change the energy and technique?

Published on: 3rd April, 2020

OCLC Number/Unique Identifier: 8576354289

Background: Pulmonary vein isolation (PVI) is the accepted standard nowadays for atrial fibrillation (AF) ablation. The most widespread ablation techniques are cryoballoon (CB) and point-by-point radiofrequency (RF) ablation. Comparative studies between both techniques have shown their equivalence for the first ablation procedure, but no trial has explored the potential incremental benefit of crossing over the ablation technique after AF recurrence. Objective: To explore the potential incremental benefit of a crossover ablation strategy for AF recurrences, comparatively with repeating the same ablation energy used for the first procedure. Methods: Retrospective analysis of patients undergoing a second AF ablation procedure after documented AF recurrence. Patients were excluded if all 4 PV were isolated at the beginning of the second procedure or extra-PVI ablation was used for the second procedure. Crossover group (n = 16) included patients in which two different techniques were used for the first and second procedure (CB-RF or RF-CB). Control group (n = 23) for those with same ablation procedure (RF-RF of CB-CB). Acute procedure end-point was PVI of all four pulmonary veins. Patients were followed-up at 3, 6, and 12 months with an electrocardiogram and a 24 h-holter. Arrhythmia-free survival at 1 year after the second ablation procedure was studied, comparing efficiency and safety of the two approaches (crossover vs. same energy). Success was defined as freedom from AF or atrial tachycardia lasting > 30 s off antiarrhythmic drugs (AADs) Results: A cohort of 39 paroxysmal and persistent AF patients was analyzed. PVI after the second procedure was 100% in all patients in both groups. There were no baseline relevant differences between the two groups. No deaths or hospitalizations occurred during follow up (data censored at 24h moths). At 1 year, arrhythmia free-survival was significantly higher in the crossover group compared to control group [93,3% vs. 47,8%; HR 0.19 (0.06-0.66);p = 0,009]. Conclusion: Crossing the ablation technique (point-by-point radiofrequency or cryoballoon PVI) after AF recurrence significantly improved arrhythmia free-survival at one year, despite no difference in acute success (PVI isolation). Randomized controlled trials with a higher amount of patients are needed to confirm the results and widespread this approach.

Case report: contrast imaging in the setting of venous thrombosis

Published on: 28th February, 2023

Disruption to contrast agent supply chains for radiology investigations has become an additional consequence of the COVID-19 pandemic. Various recommendations, including dose reductions and choices of alternative agents, have been made to help account for this limited availability. This case demonstrated how two separate CT venograms with different contrast agents, undertaken on the same day for the same patient, yielded different results; venous thromboses were more prominent in the subsequent scan. Although there was some evidence of venous sinus thrombosis on the first scan, repeat imaging was required to further characterize the lesions identified. The case exemplifies the notion that diagnostic imaging should always be guided by a detailed history and examination. It also raises the discussion point of whether more strict or uniform protocols should be developed to facilitate contrast administration for radiology investigations. It is important that appropriate doses are always administered to maximize diagnostic yield.

Pituitary gland metastasis from breast cancer: case report

Published on: 26th May, 2022

OCLC Number/Unique Identifier: 9524460826

Cancer metastasis to the pituitary gland is rare, but in most cases, it originates from a late-stage breast tumor or lung cancer. The most common symptoms of metastasis to the pituitary gland are diabetes insipidus and visual disturbance. The common site of metastasis is the posterior portion of the pituitary gland because it is highly vascularized. Metastases to this site represent 1% of all tumors [1]. Metastasis to the pituitary gland is difficult to diagnose by hormonal analysis and magnetic resonance imaging of the brain and requires biopsy for confirmation [2].

Evaluation of long antigen exposition dendritic cell therapy (LANEX-DC®) in the adjuvant treatment of pancreatic cancer – results of a single center analysis

Published on: 25th July, 2022

OCLC Number/Unique Identifier: 9575035340

Introduction: Even after surgical resection and adjuvant chemotherapy in pancreatic cancer the 5-year disease-free survival times (DFS), as well as overall survival rates (OS), are still low and median survival times are below 2 years. Here we retrospectively analyzed the outcome of immunotherapy in the additional adjuvant treatment of pancreatic cancer with long antigen exposition dendritic cell therapy (LANEX-DC®) in 28 patients who were treated at our institution. Patients: Data were available from 28 patients. Dendritic cells (LAEX-DC®) were produced according to a recently published protocol.Results: Therapy was well tolerated and no serious side effects were observed. The median disease-free survival times and the median survival times were 16,9 months and 29,4 months respectively. Five-year DFS and OS were 14,3% and 17,9%. Conclusion: We were able to show in a small cohort of patients that additional treatment with dendritic cells (LANEX-DC®) is highly effective and extends the median disease-free survival times as well as the median survival in the adjuvant treatment of pancreatic cancer, whereas the five-year overall survival still remains unsatisfactory.

The clinicopathological correlates of Cystoisosporiasis in immunocompetent, immunocompromised and HIV-infected/AIDS patients, but neglected in SARS-COV-2/COVID-19 patients?

Published on: 20th January, 2021

OCLC Number/Unique Identifier: 8897954051

Cystoisosporiasis (formerly isosporiasis) is caused by Cystoisospora belli (erstwhile named Isospora belli) is encountered globally, particularly in tropical and subtropical regions. Cystoisosporiasis is a human intestinal disease whose etiology is the parasite Cystoisospora belli with infection frequent in immunocompromised subjects, principally HIV-infected and AIDS patients. This coccidium parasite infects the epithelial cells and lining of the villi of the small and large intestines. C. belli is the least frequent of the three intestinal coccidia, viz: Cryptosporidium, microsporidium and C. belli which perturb humans. The clinical presentation of cystoisosporiasis gives a semblance of inflammatory bowel disease and irritable bowel syndrome, as well as other gastrointestinal symptoms, nausea, vomiting and diarhoea found in COVID-19, AIDS and HIV-infected patients. Research has not presented comorbid features of COVID-19 and cystoisosporiasis. The oocytes of C. belli are visualizable microscopically on wet mounts via bright-field, differential interference contrast (DIC) and epifluorescence. Trimethoprin sulfamethoxazole constitute the normal treatment of choice. C. belli,HIV-infected/AIDS and COVID-19 patients have clinicopathological correlates necessary to elucidate comorbidities and mechanisms of the diseases.

Reverse Breech Extraction versus Vaginal Push before Uterine Incision during Cesarean Section with Fully Dilated Cervix and Impacted Fetal Head

Published on: 10th October, 2023

Purpose: To compare between the two commonly used methods to deliver the fetus in emergency cesarean section with fully dilated cervix and impacted fetal head; vaginal push up of the fetal head and reverse breech extraction regarding safety and efficacy.Methods: A retrospective observational study was conducted 152 women underwent emergency CS with fully dilated cervix and impacted fetal head were divided into two groups; Group 1, vaginal push (n = 96) and Group2, reverse breech delivery (n = 56). Data variables were collected and analyzed to evaluate whether either method is more safe regarding maternal and fetal outcomes.Results: There was a significant higher percentage of extension of uterine incision in group 1 (p = 0.002). Also, there were significant higher mean values of operative time and operative blood loss in group 1 (p = 0.008 and 0.015; respectively). On the other hand, there was a significantly shorter uterotomy to delivery time in group 1 (p < 0.001). There was a significantly higher mean value of APGAR score at one minute in group 1 (p = 0.043) but no significant difference between the two groups regarding APGAR score at five minutes, atonic PPH, postoperative blood transfusion and hospital stay.Conclusion: Vaginal push technique was associated with significantly higher intraoperative maternal morbidity but postoperative maternal morbidity and fetal outcomes were comparable between both groups. Push method (after uterine incision) is still the preferable method and larger studies are required to assess the fetal safety with reverse breech extraction.

Coexistence of common gallstones and sinusoidal obstruction syndrome: Case report and review of the literature

Published on: 15th October, 2021

OCLC Number/Unique Identifier: 9305369903

Purpose: The sinusoidal obstruction syndrome (SOS) of the liver is an obliterative vasculitis that involves the terminal branches of the hepatic venules and sinusoids. When it is not treated, it will be a serious risk of mortality. Here, we aim to present our patient who has been associated with recurrent cholangitis attacks due to cholelithiasis and choledocholithiasis and is associated with sinusoidal obstruction syndrome with the literature.Description of the case: A 30 years old male patient had complaints of abdominal pain and nausea for a long time. The patient had a history of choledocholithiasis and cholangitis attacks. Although ERCP was performed and a stent was placed in the biliary tract, his jaundice did not disappear. Liver function tests were high. Tumor markers were negative.Methods: We could not make a definitive diagnosis with imaging methods and biopsy and we planned surgery. We performed segmental liver resection and biliary diversion in the surgery. Histopathological examination of the resected liver tissue was compatible with SOS.Conclusion: Many studies have been done on the etiology of SOS and different causes have been revealed. Accompanied with clinical findings, a definitive diagnosis is made with the exclusion of the presumptions considered. Surgery can be performed for both diagnostic and therapeutic purposes. If patients with elevated liver function tests and bilirubin have long-term abdominal pain, SOS should be bear in mind.
