Pediatric brainstem glioma

Published on: 3rd January, 2022

OCLC Number/Unique Identifier: 9396216057

Background and objectives: Brainstem gliomas are tumors of the central nervous system which have varying presentations and clinical courses. This study aims to analyze the frequency, clinical and therapeutic aspects of brainstem glioma.Methods: We retrospectively analyzed the data from the record of the patients treated for brainstem glioma under the age of 20 between January 2007 and July 2020 in the Radiation Oncology department of the Ibn Rochd UHC.Results: There were fifteen patients (10 males and 5 females). The mean age of onset was 12 years (range 8 - 14 years). The duration of symptoms varied from 1 month to 2 years. Nine of the patients had intracranial hypertension due to hydrocephalus, six had cranial nerve deficits at presentation, and five patients had cerebellar signs. The lesion was pontine in 12 cases. None of the patients had a tumoral resection, nine had a ventriculo-peritoneal shunt insertion for the hydrocephalus and three had a Stereotactic biopsy that revealed one astrocytoma grade 1, one low grade glioma and one glioblastoma. The radiotherapy was indicated in all the cases but only nine patients had a 3D radiotherapy with a total dose of 54 Gy. Three patients received chemotherapy. Six patients are still alive, two are lost to follow up and seven patients are dead with a mean survival period of 8 months.Conclusion: Brainstem glioma is a devastating disease with a bad prognosis. The clinical presentation is variable and the management is multidisciplinary. Our study illustrates the importance of treatment by radiation.

OCLC Number/Unique Identifier: 9390769614

Aim: The purpose of this study was to evaluate the effect of Titanium dioxide and Gold nanoparticles surface treatment on the flexural strength of Polymethyl methacrylate (PMMA) Heat cure denture base resins.Materials and methods: A total of thirty PMMA Heat cure denture base resin test samples were fabricated of size 65 x 10 x 2.5 mm (rectangular shaped) according to ADA specification no.2. The samples were divided into three groups as Conventional PMMA heat cure denture base resin samples (GROUP I, n = 10 CONTROL), PMMA Heat cure denture base resin samples coated with Titanium dioxide nanoparticles (GROUP II, n = 10) and PMMA Heat cure denture base resin samples coated with Gold nanoparticles (GROUP III, n = 10). GROUP II and GROUP III PMMA Heat cure denture base resin test samples were coated by Magnetron sputtering. Flexural strength of GROUP I, GROUP II and Group III was evaluated by a three-point bend test using a Universal testing machine and the mean values were obtained.Results: The Mean flexural strength of GROUP I, GROUP II and GROUP III samples were 114.79 MPa, 142.48 MPa and 154.70 MPa respectively. On comparative evaluation of the flexural strength among the three groups GROUP III PMMA Heat cure denture base resin samples exhibited the highest flexural strength followed by GROUP II and least by GROUP I. The statistical analysis by ANOVA had shown that there is significance in flexural strength among the groups tested (p - value = 0.000*).Conclusion: Within the limitations of the study, PMMA heat cure denture base resin coated with Gold nanoparticles showed the highest flexural strength followed by PMMA Heat cure denture base resin coated with Titanium dioxide nanoparticles. Conventional PMMA Heat cure denture base resin without any surface treatment showed the least flexural strength.

Outcomes of intervention treatment for concurrent cardio-cerebral infarction: a case series and meta-analysis

Published on: 18th January, 2023

Background: The concurrent occurrence of acute ischemic stroke and acute myocardial infarction is an extremely rare emergency condition that can be lethal. The causes, prognosis and optimal treatment in these cases are still unclear.Methods: We conducted the literature review and 2 additional cases at Al-Shifa Hospital, we analyzed clinical presentations, risk factors, type of myocardial infarction, site of stroke, modified ranking scale and treatment options. We compare the mortality rate among patients with combination intervention treatment (both percutaneous coronary intervention for coronary arteries and mechanical thrombectomy for cerebral vessels) and medical treatment at the hospital and 90 days after stroke. Results: In addition to our cases, we identified 94 cases of concurrent cardio-cerebral infarction from case reports and series with a mean age of 62.5 ± 12.6 years. Female 36 patients (38.3%), male 58 patients (61.7%). Only 21 (22.3%) were treated with combination intervention treatment.The mortality rate at hospital discharge was (33.3%) and the mortality rate at 90 days was (49.2%). In patients with the combination intervention treatment group: the hospital mortality rate was 13.3% and the 90-day mortality rate was: 23.5% compared with the mortality rate in medical treatment (23.5% at the hospital and 59.5% at 90 days (p value 0.038 and 0.012 respectively) Conclusion: Concurrent cardio-cerebral infarction prognosis is very poor, about a third of patients died before discharge and half of the patients died 90 days after stroke. Despite only one-quarter of patients being treated by combination intervention treatment, this treatment modality significantly reduces the mortality rate compared to medical treatment.

Anesthesia mumps: a case report

Published on: 10th February, 2023

A 25 years old pregnant woman had a painful labor in her 38th week of pregnancy. Because of a previous delivery by a cesarean section, she underwent a second cesarean section. Her past medical and family history was unimportant. We performed the surgery under spinal anesthesia. The surgery was uneventful and the baby was in a good health. After 9 hours of surgery, she complained of painless swelling in the parotid glands. Physical examination and laboratories were normal. We started rehydration with normal saline and one dose of hydrocortisone (100 mg IV route). Close monitoring showed no problems in swallowing or any purulent discharge. Two days later, we had a complete resolution of the swelling. We discharged the woman with her child with no complaints. Our case is one of the rare cases of anesthesia mumps after spinal anesthesia. Physicians should be careful in considering such rare cases. Early diagnosis and management is the key.

The risk of coronary heart disease varies with blood pressure grades and glycemic metabolism statues in a hypertensive

Published on: 30th August, 2022

Coronary heart disease (CHD) is the leading cause of death worldwide [1]. In China, the prevalence of CHD has kept continually increasing, with the number of patients being approximately 11.39 million, at present [2] and CHD poses a substantial threat to human health. Hypertension and diabetes both are the major risk factors for CHD [2,3] and the risk of CHD in patients with coexisting hypertension and diabetes is higher than that in patients with either of the two diseases [4].

The Fulcrum of the Human Heart (Cardiac fulcrum)

Published on: 3rd January, 2024

Introduction: The functional anatomy of the myocardium allows envisioning that it initiates and ends at the origin of the great vessels. In our research, we have always considered that it should have a point of attachment to allow its helical rotation to fulfill the fundamental movements of shortening-torsion (systole) and lengthening-detorsion (suction), which once found, was called the cardiac fulcrum. Materials and methods: A total of 31 hearts, arising from the morgue and slaughterhouse were used: 17 corresponded to bovids and 14 were human. Anatomical and histological studies were performed. The heart was fixed in 10% buffered formalin. Hematoxylin-eosin, Masson’s trichrome staining technique, and 4-micron sections were used for the histological study, and 10 % formalin was used as a buffer. Results: The anatomical investigations have revealed that all the hearts (bovids and humans) have myocardial support whose histological structure in the analyzed specimens presents with an osseous or chondroid-tendinous character. In this structure, which we have called the cardiac fulcrum, are inserted the myocardial fibers at the origin and end of the band, which correspond to the continuous myocardium coiled as a helix.Conclusion: This description of the fulcrum would end the problem of lack of support of the myocardium to fulfill its function of suction/ejection.

Ectopic Pregnancy Risk Factors Presentation and Management Outcomes

Published on: 29th September, 2023

Background: Ectopic pregnancy (EP) is a common and serious early pregnancy problem with a significant morbidity rate and the potential for maternal death. Women commonly present with minimal vaginal bleeding and abdominal pain.Objective: The main objective of the study was to evaluate the risk factors, clinical presentation, sites, and management outcomes of ectopic pregnancies. Methodology: It was a prospective descriptive, cross-sectional hospital-based study conducted at Bashair Teaching Hospital during the period January 2021–June 2021.An interview questionnaire was used, and eighty-two (82) women were included after informed consent. Demographic and clinical data concerning personal history, symptoms of presentation, risk, site, and type of management were recorded.Results: Ectopic pregnancy incidence was 2% and most risk factors were infection 29.3%, surgery 15.9%, miscarriage 13.4%, infertility 12.2%, tubal surgery 4.9%, previous ectopic pregnancy 4.9%, intrauterine contraceptive device (IUCD) 3.6%, and tubal ligation 2.4%. Women presented with bleeding and abdominal pain at 47.5%, bleeding at 18.3%, abdominal pain at 9.7%, and shock at 8.5%.The sites are ampullary (57.3%), fimbria (9.7%), interstitial (8.5%), isthmus (8.5%), ovarian (7.3%), cervical (4.8%), and abdominal (3.6%).Surgical management was 93.9%, medical and surgical management was 3.6% and medical management was 2.4%. A blood transfusion was received at 37.8%.Conclusion: The study concluded that women of reproductive age are at risk of ectopic pregnancy, so healthcare providers and doctors should have a high index of suspicion, prompt diagnosis, and intervention for ectopic pregnancy. Assessment of women at risk factors and modifications will reduce incidence.

Drug treatment and rehabilitation in China: Theoretical rationales and current situations

Published on: 18th February, 2021

OCLC Number/Unique Identifier: 8946740322

Global drug use has reached epidemic levels, with approximately 269 million drug users worldwide [1]. Problematic drug use may lead to serious physical, social, and mental health problems. An estimated 167,000 deaths attributed to drug-related disorders worldwide in 2017 [2]. The rising global drug use and its severe adverse consequences make the drug treatment/rehabilitation a top priority for policymakers. In modern China, illicit drug use has raised great concern from both the academia and the public. Nearly 2.15 million Chinese were registered as drug users in 2019 [28]. Drug-related crimes and deaths are also increasing [29]. The current drug treatment programs in China are mainly compulsory, addressing coercion and discipline. However, the effectiveness was found to be low [3]. Situated in the fields of social work, public health, and psychology, Chinese scholars and practitioners have conducted some empirical tests for these drug treatment/rehabilitation programs and already found several effective preventive factors in the programs. However, the existing research on the design and evaluation of Chinese drug treatment/rehabilitation programs rarely investigate the theoretical rationales behind these programs. This study would address three criminological theories that have been applied to explain drug treatment and rehabilitation in Western societies: Differential Association Theory, Social Bonding Theory, and Labeling Theory. Similar theoretical rationales could be learnt and adopted by Chinese programs.

Myocardial fibrosis in aortic stenosis: comparison between clinical data, laboratory, echocardiography, and cardiac magnetic resonance

Published on: 16th May, 2023

Introduction: Patients with aortic stenosis often develop hypertrophy and fibrosis, regardless of symptoms. Cardiac Magnetic Resonance (CMR) represents the gold standard for the evaluation of fibrosis despite numerous limitations: cost, availability, atrial fibrillation, claustrophobia, kidney failure or inability to apnea.Purpose: The aim is to validate the role of echocardiographic parameters, such as Global Longitudinal Strain (GLS), as early markers of fibrosis. Clinical and laboratory data, particularly B-type Natriuretic Peptide (BNP), were also analyzed.Material and methods: In our study we recruited 33 patients with severe aortic stenosis, correlating echocardiographic values of GLS with the qualitative analysis of Late Gadolinium Enhancement (LGE) and the quantitative analysis of T1 mapping of CMR.Results: 70% of patients with an alteration of GLS had LGE+. Univariate logistic regression shows that the factors associated with the presence of LGE on CMR are hypertension (p = 0.043), GLS (p = 0.032), and elevated BNP values (p = 0.021); for GLS, Odds Ratio (OR) is 5 so the chance of finding fibrosis on CMR increases 5 times in presence of an altered GLS. The multivariate analysis confirms the association with impaired GLS values (p = 0.033) and hypertension (p = 0.025), but not with elevated Pro-BNP values.Conclusion: In patients with severe aortic stenosis, the association between GLS, LGE, and T1 mapping can help identify earlier those patients with structural changes caused by the disease, who could benefit from early intervention. It remains to be established how the presence of these alterations has a role in determining the intervention time and the outcome of these patients.
