Enhanced fingerprint classification through modified PCA with SVD and invariant moments.

This research introduces a novel MOMENTS-SVD vector for fingerprint identification, combining invariant moments and SVD (Singular Value Decomposition), enhanced by a modified PCA (Principal Component Analysis). Our method extracts unique fingerprint features using SVD and invariant moments, followed by classification with Euclidean distance and neural networks. The MOMENTS-SVD vector reduces computational complexity by outperforming current models.

Real-time temperature anomaly detection in vaccine refrigeration systems using deep learning on a resource-constrained microcontroller.

Maintaining consistent and accurate temperature is critical for the safe and effective storage of vaccines. Traditional monitoring methods often lack real-time capabilities and may not be sensitive enough to detect subtle anomalies. This paper presents a novel deep learning-based system for real-time temperature fault detection in refrigeration systems used for vaccine storage.

Globe-LFMC, a global plant water status database for vegetation ecophysiology and wildfire applications.

Globe-LFMC is an extensive global database of live fuel moisture content (LFMC) measured from 1,383 sampling sites in 11 countries: Argentina, Australia, China, France, Italy, Senegal, Spain, South Africa, Tunisia, United Kingdom and the United States of America. The database contains 161,717 individual records based on in situ destructive samples used to measure LFMC, representing the amount of water in plant leaves per unit of dry matter. The primary goal of the database is to calibrate and validate remote sensing algorithms used to predict LFMC.

A Prospective Assessment of Adverse Events in 3 Digestive Surgery Departments From Central Tunisia.

Objective: The aim of the study was to prospectively assess the incidence, the preventability, and the factors contributing to adverse events (AEs) in surgical departments of Tunisian hospitals.

Methods: A prospective longitudinal study evaluated the incidence of AEs in surgical departments of three university hospitals in central Tunisia. The study followed 1687 admitted patients until their discharge from the hospitals based on a standard two-stage method that first included staff interviews and review of medical records based on 18 criteria and later was followed by an expert review to confirm or reject the presence of an AE.

[Epidemiological, clinical features, therapeutic results and evolution of gastrointestinal stromal tumour: about 25 cases].

Background: Gastrointestinal stromal tumors (GIST) are mesenchymal tumors occuring in the majority of cases in the stomach and small intestine, rarely in rectum, colon, esophagus or mesentery. They are derived from cells of cajal or their precursor, and are typically CD117/KIT + (95%), CD34 + (70%).

Aims: is to study the epidemiological, clinical, therapeutic and evolution of gastrointestinal stromal tumors.

[Implementation of the safe surgery checklist of the World Health Organization at the University Hospital of Monastir (Tunisia)].

Objective: To evaluate the impact of introduction of the WHO safe surgery checklist in the university hospital of Monastir over a period of five months.

Methods: We conducted a longitudinal study (before - after) with evaluation of five result indicators which were: percentage of surgical site infections, not prescribed antibioprophylaxis, unplanned return to the operating room, postoperative length of stay and postoperatively death.

Results: We identified 185 patients during the period and 323 patients after the introduction of the WHO checklist.

Autoimmune pancreatitis mimicking pancreatic cancer.

Context: Autoimmune pancreatitis is a particular type of pancreatitis of presumed autoimmune etiology, it is an entity distinct from all others forms of chronic pancreatitis, characterized by clinical, histopathological, radiographic, serologic and therapeutic features. This benign disease resembles pancreatic carcinoma both clinically and radiographically.

Case Report: A 27-year-old man presented with obstructive jaundice and evocative image of pancreatic tumor.

Epstein-Barr virus DNA quantification and follow-up in Tunisian nasopharyngeal carcinoma patients.

The prognostic value of the Epstein-Barr virus (EBV) DNA load in sera of nasopharyngeal carcinoma (NPC) patients measured before any treatment, after treatment and before relapse was assessed. The real-time polymerase chain reaction was used to detect the viral load levels among 74 NPC subjects. Patients were followed up for a period going from 1 to 6 years (median 4 years).

Lack of association between human leukocyte antigen-E alleles and nasopharyngeal carcinoma in Tunisians.

Nasopharyngeal carcinoma (NPC), a cancer with a remarkable geographical and worldwide ethnic distribution, has been strongly associated with human leukocyte antigen (HLA) class I genes. The presence of additional HLA risk factors has been suggested by several reports. In the present study, we analyzed the implication of HLA-E gene polymorphisms in NPC susceptibility in Tunisians, a population characterized by an intermediate incidence of NPC with specific clinical features.

Association of HLA-G polymorphisms with nasopharyngeal carcinoma risk and clinical outcome.

The expression of human leukocyte antigen-G (HLA-G) in tumor cells may facilitate the escape of the tumor from immunosurveillance; thus the aim of this study was to evaluate the influence of HLA-G polymorphisms occurrence on nasopharyngeal carcinoma (NPC) susceptibility, severity, and survival. Using the restriction fragment length polymorphism-polymerase chain reaction and the amplification refractory mutation system-polymerase chain reaction method, 186 Tunisian patients and 189 healthy controls were genotyped for nonsynonymous polymorphisms in HLA-G codon 31Thr/Ser, codon 110Leu/Ile and codon 130Leu/framshift. When allele, genotype and haplotype frequencies between patients and controls were compared for each single nucleotide polymorphisms (SNP), no statistical significant differences were observed.

[Embolic pseudotumor diagnosed by surgery].

We report a case of pulmonary infarction in a 72-year-old woman who was hospitalised for hemoptysis, chest pain and weight and coin a lesion in the loss periphery of the left lower lobe. Camputed tomography of the chest demonstrated a sub pleural solitary nodule with spicular radiation. Video-assisted thoracoscopic surgery was performed to obtain a histological diagnosis.

[Pathomimia in upper limb].

Pathomimia, or factitious disorders, are characterized by producing symptoms voluntarily with the intention of playing the role of the patient. Inspite of being considerd as a psychatric disorder, pathomimuia is often encountered in the daily professional life of doctors without being recognized or diagnosed. There are various clinical aspects of pathomimia.

[Intussusception in adults. Thirteen case reports].

This study was retrospective. The authors analyse the clinical, etiological and therapeutic aspects of the intestinal intussusception based on 13 adults observed over 14 years in the surgical department of the university hospital in Monastir. This disease was rare because accounted for 2.

[Necrotizing fasciitis of the thigh].

Introduction: Necrotizing fasciitis is a rare and severe infectious disease with infectious necrosis often extending in depth to the subcutaneous tissue in the absence of rapid medical-surgical treatment. We report two cases of necrotizing fasciitis of the thigh, which underline the principle clinical and therapeutic characteristics of this often underrated disease.

Observation: The first case concerns a young 21 year-old woman without remarkable medical history who, following injury from the thorn of a palm tree, developed an aerobic germ necrotizing fasciitis which regressed following medical-surgical treatment.
