Rare Case of Recurrent Adamantinoma of the Tibia: Limited Efficacy of Pazopanib as a Standalone Treatment.

BACKGROUND Adamantinoma is a rare low-grade malignant bone tumor, usually found in the tibial diaphysis and metaphysis, with histological similarities to mandibular ameloblastoma. The most effective treatment of recurrent adamantinoma is not yet clear. This report is of a 22-year-old woman with recurrent tibial adamantinoma treated with the tyrosine kinase inhibitor pazopanib. CASE REPORT We report the case of a 22-year-old woman who was referred to our center for a suspicious bone lesion in the right tibia. Bone biopsy findings were consistent with an adamantinoma. En bloc resection was completed successfully, with no postoperative complications. Five years later, a positive emission tomography scan revealed mildly increased tracer uptake near the area of the previous lesion and in the right inguinal lymph node. Biopsies of the lesion and inguinal lymph node confirmed recurrence of the adamantinoma. Due to abdominal and pelvic metastasis, the patient underwent surgical debulking, along with an appendectomy, right salpingo-oophorectomy, intraoperative radiation therapy, and hyperthermic intraperitoneal chemotherapy. Subsequently, the patient was placed on pazopanib for 4 months; however, her tumor continued to worsen after 4 months of chemotherapy. Currently, the patient is receiving gemcitabine and docetaxel as second-line medical therapy. CONCLUSIONS This report showed that pazopanib as standalone treatment does not appear to have promising role on patient outcomes. To the best of our knowledge, this is the second report of pazopanib in the treatment of adamantinoma.

Donor blood cultures and outcomes after lung transplantation: a single-center report.

BACKGROUND: Transplanting lungs from donors with positive blood cultures has not been shown to adversely affect survival. There is limited evidence for potential effects on other outcomes, such as hospital course, graft function, and transmission of infection. METHODS: This retrospective cohort study included adult patients who underwent lung-only transplantation for the first time between March 2010 and December 2022. Outcomes of patients whose donors had positive blood cultures within 72 h of transplant were compared to patients whose donors had negative blood cultures. RESULTS: Twenty-five (10.8%) of 232 donors had positive blood cultures, including a single, unexpected case with candidemia. The most commonly isolated bacteria were Enterobacter cloacae (n = 5), Klebsiella pneumoniae (n = 5), Acinetobacter baumannii (n = 3), Pseudomonas aeruginosa (n = 3), and Staphylococcus aureus (n = 3). Eleven donors had identical bacteria in their respiratory cultures. All patients who were transplanted from donors with positive blood cultures survived beyond 90 days. Positive donor blood cultures were not associated with longer hospital stay, in-hospital complications, acute cellular rejection, or the achievement of 80% predicted forced expiratory volume in the first second. Probable transmission of donor bacteremia occurred in only two cases (both with S. aureus). These two donors had positive respiratory cultures with the same organism. CONCLUSION: The study did not find an increased risk of adverse events when transplanting lungs from donors with positive blood cultures. Allograft cultures may be more predictive of the risk of transmitting infections.

Frontonasal Encephalocele Complicated With Pseudotumor Cerebri: A Case Report and Literature Review.

Primary pseudotumor cerebri syndrome (PPTS) is a rare disorder of elevated intracranial pressure (ICP) in the absence of an identifiable underlying etiology. Afflicted patients are usually obese women in their reproductive age presenting with symptoms of elevated ICP. Seldom, patients can present with an encephalocele. We reported a case of a 31-year-old female who initially presented to our center with complaints of headaches, foreign body sensation in the nasal cavity, and decreased ability to smell. Brain computed tomography (CT) scan showed a large intranasal encephalocele and defect along the frontal skull base, through which brain tissue was herniating. The patient was successfully treated surgically by implantation of a lumboperitoneal shunt to manage the high ICP caused by her PPTS. In combination, reconstruction of the frontal skull base defect for the encephalocele was performed. Currently, the patient is doing well despite some on-and-off headaches.

COVID-19 Infection Among Healthcare Workers at a Tertiary Healthcare Hospital.

PURPOSE: SARS-CoV-2 or COVID-19 virus was the culprit of the global pandemic that began in 2019. With alarming mortality rates reaching sky-high worldwide, the virus prompted the masses to switch to online working. However, this was not feasible for healthcare workers (HCWs) exposed to a higher-than-normal risk of acquiring COVID-19 infection. This study aims to observe the prevalence of COVID-19 positivity among the various areas of a healthcare facility in Saudi Arabia. METHODS: A cross-sectional study of positive employees among all departments at a tertiary care hospital in Riyadh, Saudi Arabia, such as administration, capital projects/facilities, and healthcare. The study included all hospital employees-permanent staff, rotating physicians, and trainees-who tested positive for COVID-19 between March 20, 2020 and December 30, 2020. RESULTS: It was found that HCWs had the most significant number of infected individuals with nursing staff being the predominant demographic. This was followed by the capital projects/facilities departments, of which the environmental services staff were the most infected. CONCLUSION: It is pertinent that strict protocols be taken by hospital management to limit the spread of future infectious diseases within hospital settings. This includes the provision of personal protective equipment (PPE) and adequate education on its proper usage, alongside regular surveillance of staff with regard to adherence and early detection of symptoms.

Clinical and Demographic Characteristics of Families Attending the Epilepsy, Neuromuscular, and Child Wellbeing Clinics.

Background Neurological diseases entail a broad spectrum of disorders. Among such ailments are epilepsy and neuromuscular disorders which impose a substantial burden on children and their families. Ensuring adequate access to outpatient services is crucial for these children regardless of the subclinical specialty, and clinicians can better comprehend the caregivers' perspectives by being aware of their backgrounds which can be aided using epidemiological studies. Methods In June 2023, a cross-sectional study was carried out in pediatric neurology clinics at a tertiary care center. The study included all families with a child or more (14 years and younger) diagnosed with neurological disorders. The study adopted a three-section survey delivered to participants recruited using a non-probability sampling technique to achieve a 95% confidence interval with a 5% margin of error. Results A total of 821 families participated in this study. The mean age of respondents was 40.46±8.72 years. Of the affected children, there were 600 (73.08%) children following up with the general neurology and epilepsy clinics, 164 (19.98%) were following up with the neuromuscular disorders clinics, and 57 (6.94%) were following up with the neurogenetic clinics. Familial status had no association with the type of clinic the patient was following up with p=0.0054. Single respondents had a significantly higher prevalence of children with epilepsy (p<0.0001). Parents with a high school level of education or lower had a significantly greater prevalence of epilepsy clinic follow-ups (p=0.0048). Conclusion The findings of this study contribute to the assessment of prevalent neurological disorders in children and shed light on the family dynamics surrounding these conditions. Through statistical analysis, the study establishes connections between certain demographic and clinical traits and specific neurological disorders among pediatric patients and their families. The study emphasizes the importance of socio-economic and socio-clinical support in promoting child health in such cases. Similar research would offer a more accurate portrayal of the challenges faced by families in these circumstances.

COVID-19 Contact Tracing Experience at a Tertiary Healthcare Center in Saudi Arabia.

Introduction As of May 2023, the end of the pandemic, the cumulative number of COVID-19 cases reached more than 841,000 cases. Healthcare workers (HCWs) especially have been at the frontline during this pandemic and are at a higher chance of contracting COVID-19. Approximately half of all high-risk exposures were to healthcare personnel with COVID-19. While several tools for contact tracing were developed for the general public, contact tracing for infectious diseases in the healthcare setting is limited, and global testing of HCWs, or in-hospital digital tracing, is not performed in most facilities. The King Faisal Specialist Hospital and Research Center (KFSH&RC) collaborated with the Infection Control and Health Information Technology Affairs (HITA) to create an automated COVID-19 contact tracing tool specifically for HCWs who worked at the institute. This study aims to describe the contact tracing experience at KFSH&RC. Methods A retrospective study was conducted to describe the use of an automated tool that was developed to assist in the contact tracing process and that was to be used by KFSH&RC employees who had been in contact with a COVID-19-positive individual. This tool is utilized for the early identification of possible COVID-19 cases and risk stratification of the exposed individuals. The tool can be accessed through the KFSH&RC website; it also collects information about the COVID-19 exposure rate among the different departments such as administration, capital projects/facilities, and healthcare at a tertiary care hospital in Riyadh, Saudi Arabia Results The tool has been utilized 7,353 times by contact cases. Approximately 7% of those tested later developed a COVID-19 infection. When assessing the positivity rates per department, The Environmental Services Department had the highest positivity rate of 28.21%, followed by Health Information Technology and Analytics (HITA), and then the Central Transportation Department. Conclusion This study acts as the first of its kind to describe the successful use of the healthcare contact tracing system in one of Saudi Arabia's largest hospitals (KFSH&RC) and describe the infection trends in different departments of the hospital. Through the tracing system, the departments with the highest COVID-19 infection occurrences at the hospital were identified in a timely manner, and safety protocols were implemented.

A native mitral valve mass beyond imagination.

The authors report a case of a patient with a history of IgA nephropathy that, during the admission for pneumonia, was found to have an incidental finding of a huge mitral valve (MV) mass on transthoracic echocardiography. The differential diagnosis was challenging because the clinical scenario raised the suspicion of possible infective endocarditis and the imaging features were suggestive of a myxoma or vegetation. The patient underwent urgent excision of the mass with MV replacement due to the high risk of embolism. Intraoperative findings were consistent with clot or vegetation. Pathology result of thrombus was beyond our imagination and at the best of our knowledge one case only has been reported. Awareness about native MV thrombosis and its etiologic factors, workup, and management is key for better medical and surgical management planning because this condition is extremely rare and challenging in the clinical and imaging arena.

A Case Report of Successful Use of Twice-Daily Letermovir in the Treatment of Resistant Cytomegalovirus in a Small Bowel Transplant Recipient.

Cytomegalovirus (CMV) is considered one of the most notable pathogens that affect patients after solid organ transplantation (SOT), especially small bowel transplant patients with a risk of high mortality rate. Its management relies historically on the use of CMV DNA polymerase inhibitors (namely, ganciclovir and valganciclovir). Second-line options include foscarnet and cidofovir, which are highly nephrotoxic and thus less preferred and only used in ganciclovir intolerance or resistance cases. Letermovir is a novel antiviral agent approved for CMV prophylaxis in hematopoietic stem cell transplant, but not for SOT (neither for prophylaxis nor for treatment). We report the first case on the successful use of letermovir in treating CMV disease in a small bowel transplant patient who failed to achieve viral clearance due to ganciclovir resistance and severe intolerance to foscarnet.

Trends in socio-economic inequalities in female mortality, 2001-08. Intercensal estimates for England and Wales.

BACKGROUND: This article presents estimates of annual mortality rates for women of working age by the National Statistics Socio-economic Classification (NS-SEC) for the period 2001 to 2008. Until recently, it was possible to produce such mortality rates only at the time of the decennial census when populations are enumerated by occupation and NS-SEC. In 2010, ONS published annual intercensal male mortality rates using the Labour Force Survey (LFS) to provide population estimates by age and NS-SEC. This article produces the corresponding estimates for women aged 25 to 59. METHODS: The LFS was used to estimate female populations by age and NS-SEC for each year between 2001 and 2008. Numbers of deaths were obtained from death registrations. For both deaths and populations, the combined method of NS-SEC classification was used, whereby the most advantaged of a married woman's and her husband's NS-SEC was used to assign the woman to an NS-SEC class. Single women were classified according to their own NS-SEC. Age-standardised mortality rates were derived for each NS-SEC class by year and a number of measures of inequality estimated for each year so that any trends could be identified. RESULTS: While overall mortality rates for women declined over the period, this was not true for all NS-SEC classes. Managerial and professional occupations and Routine occupations experienced a statistically significant decline in mortality rate over the period. There was no clear trend for the other classes. Absolute measures of inequality showed no clear trend over the period, but relative inequalities tended to increase. Routine occupations had the greatest decline in mortality rate over the period of approximately five deaths per 100,000 per annum. CONCLUSIONS: Socio-economic inequalities in the mortality rates of women appeared to increase between 2001 and 2008. However, the results for women were not as clear as for men with four out of the seven analytic NS-SEC classes not having a statistically significant downward trend in mortality. The degree of annual volatility in the measures suggests that at the current low levels of mortality of working age women, the LFS could not be used to provide population denominators below the national level. Possibly, three-year moving averages would be better trend indicators, but this would reduce the timeliness of the data to some extent.

Social inequalities in alcohol-related adult mortality by National Statistics Socio-economic Classification, England and Wales, 2001-03.

BACKGROUND: This article is the first analysis of the social inequalities in adult alcohol-related mortality in England and Wales at the start of the 21st century, using the National Statistics Socio-economic Classification (NS-SEC). It presents the socio-economic patterns of alcohol-related mortality by gender, age and region, for England and Wales as a whole, Wales and the regions of England. METHODS: Death registrations provided the number of deaths for working age adults, using the National Statistics definition of alcohol-related mortality. Population estimates for England and Wales in 2001-03 were used to estimate alcohol-related mortality rates by sex, five-year age group, NS-SEC and region. Inequalities were measured using ratios of alcohol-related mortality rates between the least and most advantaged classes. RESULTS: There were substantial socio-economic variations in adult alcohol-related mortality, with the inequalities being greater for women than for men. The mortality rate of men in the Routine class was 3.5 times those of men in Higher and Managerial occupations, while for women the corresponding figure was 5.7 times. Greater socio-economic inequalities in mortality were observed for men aged 25-49 than for men aged 50-64; however the highest mortality rate of men occurred for Routine workers aged 50-54. Women in the Routine class experienced mortality rates markedly higher than other classes. The highest mortality rate of women also occurred for Routine workers, but at a younger age than for men (45-49). Within England, the North-West showed the largest inequalities, with particularly high rates in the Routine class for both sexes. In general, there was no association between levels of mortality and socio-economic gradients in mortality across the English regions and Wales. CONCLUSIONS: Rates of alcohol-related mortality in England and Wales increased significantly for people between the early 1990s and early 21st century, and were substantially greater for those in more disadvantaged socio-economic classes. There is also evidence that these socio-economic differences were greater at younger ages, especially for men at ages 25-49.

Social inequalities in fatal childhood accidents and assaults: England and Wales, 2001-03.

BACKGROUND: This article presents age-specific mortality rates of children for selected causes of accidents and assault using the National Statistics Socio-economic Classification (NS-SEC). The study is an analysis of the social inequalities in fatal childhood accidents and assault at the start of the 21st century. It aims to identify the causes and age groups for which these inequalities are the widest. METHODS: In order to classify children by NS-SEC, the most advantaged class of the biological or adoptive parents was used. Death registrations provided the number of deaths from accidents and assault for children aged from 28 days to 15 years, in England and Wales, between 2001 and 2003. The population of children by NS-SEC and age group was obtained from the 2001 Census. Age-specific mortality rates were estimated. Inequalities were measured using socio-economic gradients in mortality. RESULTS: There were wide social inequalities in fatal accidents and assaults for children aged between 28 days and 15 years. The overall mortality rate in the routine class was 64 per million children aged up to 15, 4.5 times the rate of children with parents in the higher managerial and professional class. The greatest inequalities in accidental mortality for children in that age group were observed for fire and pedestrian accidents, followed by accidental suffocation. Infants at least 28 days but less than one year were subject to the widest inequalities of all age groups in fatal accidents and assault. The highest mortality rate in this study resulted from assault on babies whose parents could not be classified by occupation. Pedestrian and other transport accidents were the greatest causes of death for children between 5 and 15 years old. Inequalities were much larger for pedestrian than for other transport accidents for children aged 14 years and under. The leading cause of death for children aged less than five years was suffocation, followed by drowning and exposure to fire/hot substances. In that age group, the risk of death from exposure to fire was significantly higher for children whose parents could not be classified by occupation. CONCLUSIONS: Substantial social inequalities in childhood mortality from accidents and assault existed in 2001-03. Reducing the large inequalities between the most advantaged class and the most disadvantaged group in the non-occupied category, would make a substantial impact on childhood deaths from accidents and assaults. If the mortality rates in the latter group were the same as in the most advantaged managerial and professional class, deaths of infants of at least 28 days but less than one year, from assault would be reduced by 62 per cent. Deaths from fire, accidental suffocation and pedestrian accidents in the under fives would be reduced by 50 per cent, 25 per cent and 28 per cent respectively. Deaths in pedestrian and transport accidents for children aged 5-15 would be reduced by 25 per cent and 16 per cent respectively.

Social inequalities in female mortality by region and by selected causes of death, England and Wales, 2001-03.

This article reports on social inequalities in female mortality by region and cause of death for women aged 25-59 years in England and Wales in the period 2001-03. It is the first official compilation of detailed mortality statistics for women based on the National Statistics Socio-economic Classification (NS-SEC). It is part of a series of articles measuring inequalities in adult mortality. The results demonstrate a strong socio-economic effect on the mortality of women in all regions. This pattern remained consistent between regions. There were marked differences in the socio-economic gradient by cause. Mortality rates for women in the least and most advantaged NS-SEC classes were similar for breast cancer. In contrast, compared to women in the most advantaged class, mortality rates were three times as high for the least advantaged women for lung cancer and cerebrovascular disease, around five times as high for ischaemic heart disease and all digestive diseases, and six times as high for respiratory diseases.
