Malignant Scalp Tumors: Retrospective Analysis of 1000 Patients.

Background: Limited data on large cohort of patients with malignant tumors of the scalp are available in the literature. The aim of this study was to review a large cohort of patients with malignant scalp tumors to determine epidemilogy, tumor characteristics of this region and treatment. Materials and Method: A retrospective review of patients with malignant scalp tumors diagnosed histopathologically between 2005 and 2021 was performed. Demographic features and tumor characteristics were analyzed. Results: A total of 1080 patients (M: F 3,5:1) were treated and followed up for a mean period of 42 months (12-120 months). Age at diagnosis ranged from 12 to 98 years. Most malignant scalp tumors (95,1%) occurred in those 50 years or older and in bald patients (87%). Basal cell carcinomas (59,2%), squamous cell carcinomas (32,2%) and melanomas were the most common histologic types. Incidence was highest on the frontal of temporal region (66,1%). Recurrence was frequently in squamous and basal cell carcinomas but uncommon in melanoma. Conclusions: Tumors of the scalp accounted about 8,01 % of all skin cancers. Tend to be basal and squamous cell carcinomas, many of which occur in the temporal and frontal region of bald men. The outlook for patients with scalp tumor is positive, although we suggest excision margins of at least 3-4 mm and continued clinical vigilance is warranted given their higher recurrence rates.

Analysis on Clinical Features and Risk Factors of Death in Yunnan with Acute Mushroom Poisoning

Mushroom poisoning has become a global public health problem. However, effective treatment of toadstool poisoning and risk factors evaluation are a trouble for clinicians. A total of 137 mushroom poisoning cases were reported, of which 70 (52%) were female. Mortality was 13.1% (18). A latency of ≥6 h was seen in 87 cases (63.50%), with a mortality of 89% (16). Direct bilirubin (DB) ≥34.2 μmol/L was seen in 16 patients, and 124 cases (90.0%) occurred from June to August (summer).

HIV Screening Scenarios and Targets to Achieve 90% Sero-Status Knowledge Over 2021-2025 in Morocco – Pioneer Use Case of the Goals HIV Testing Strategies Model in a Concentrated Epidemic

Morocco applied the Goals testing model, projecting alternative testing scale-up scenarios, varying coverage targets for 13 adult populations. The model was calibrated using program service delivery, spending and surveillance data (2015-2019), integrated bio-behavioural surveys, and national HIV estimates. It projects annual diagnoses by target group from undiagnosed prevalence and testing coverage, allowing for HIV-infected people self-selecting for testing, retesting and transitions between groups. Scenarios were evaluated for knowledge status improvement and cost, focusing on 2023-2025.

Epidemiology and Multidrug Resistance of Strongyle Nematodes in Ordos Finewool Sheep

Regular whole-flock treatments and long-term repeated use of similar anthelmintics has led to the development of anthelmintic resistance and widespread epidemic of sheep nematodiasis. The current work was carried out to understand the prevalence of gastrointestinal nematodes in Ordos fine-wool sheep and to evaluate the efficacy of currently used anthelmintics.

Epidemiology of Bronchiolitis: Multicentric Study Policlinico-Garibaldi-Bronte-Caltagirone-Siracusa

Bronchiolitis is the most common infection of the lower airways of the 1st year. Infants with severe respiratory distress (2-3%) require hospital care. The aim of the study is to evaluate the frequency of Respiratory Virus (VRS) infection, the usefulness of the diagnostic score, the ventilatory support and the protective effect of vaccinations.

Cisplatin-Gemcitabine Related Cardiomyopathy in Non-Small Cell Lung Cancer NSCLC Patient: A Case Study

Gemcitabine is a pyrimidine analog and cisplatin is a platinum agent, they are usually combined to form a chemotherapeutic doublet used to treat different types of oncological cancers, including non-small cell lung cancer (NSCLC). Although these agents are not known to cause such events, few cases related to possible cardiotoxicity side effects have been reported ; including angina, chronic heart failure, arrhythmias, and cardiac ischemia. A 52-year-old African male presented with Stage IV lung adenocarcinoma metastatic to the bone, pleura and lymph node, EGFR wild type. Patient has a history of hypertension, diabetes, and atrial fibrillation and on rate control medications. He was treated initially with cisplatin-gemcitabine, after which he developed cardiomyopathy.

United States Air Force Academy: Identifying Areas at Risk for the Persistence of Plague using the Bioagent Transport and Environmental Modeling System (BioTEMS)

Introduction: Yersinia pestis, the etiologic agent of plague, has caused major pandemics in human history and continues to be both a natural and bioterrorist threat to human populations. Plague exists in nature in either an epidemic or enzootic state. Geographic models of the epidemic state have primarily been developed using flea and reservoir species, however little is known of the enzootic state and potential cryptic reservoir species and few endemic models have been produced.

Epidemiology of Sudden Unexpected Death in Infancy: Evidence from the London Metropolitan Police Project Indigo Investigation

The London Metropolitan Police in collaboration with medical personnel, study all sudden unexpected death in infancy (SUDI) <2 years in their jurisdiction, to identify suspicious cases for further investigation. The 2005-2010 Project Indigo includes extensive data on all such non-suspicious cases. Deidentified data on age and gender of 477 infants dying a natural unexpected-sudden death in London were gathered for statistical analyses, for comparison to our published a priori probability models that predict their distributions without need of superfluous information, such as race, autopsy findings, or SUDI risk factors. The total observed male fraction of 0.5639 for all these 477 Indigo cases (269 male) is predicted using a recessive X-linkage model for Sudden Infant Death Syndrome (SIDS) as 0.5676. The transformed age distribution of all 477 Indigo cases of different causes of death is modeled by a single four-parameter lognormal distribution, y = Log [(d + 9.44)/(1254 – d)] = μ + σ z, where d is Indigo age in calendar days of life (d = DOD – DOB ≥ 0), median μ = -1.085, slope σ = 0.543, and z is a standard normal deviate.

Non-ARV Prescriptions and Medication Burden among Commercially Insured U.S. HIV Patients

Accelerated aging and higher co-morbidity prevalence have increased non-antiretroviral (ARV) medications for HIV patients. We examined, over a 12 month period, non-ARV medication burden among HIV-positive patients 18-49 and ≥50 years using a comprehensive U.S. healthcare claims database in an age-and-gender matched analysis (1:3 matching ratio of cases to controls). Primary outcomes of interest included the median and mean number of unique non-ARV drug substances during the one month period with the highest number of prescriptions filled for each individual, and the mean number of unique classes of medication.
