Evaluation of the implementation of the objective structured clinical examination in health sciences education from a low-income context in Tunisia: A cross-sectional study.

Background: Objective structured clinical examination (OSCE) is well-established and designed to evaluate students' clinical competence and practical skills in a standardized and objective manner. While OSCEs are widespread in higher-income countries, their implementation in low-resource settings presents unique challenges that warrant further investigation.

Aim: This study aims to evaluate the perception of the health sciences students and their educators regarding deploying OSCEs within the School of Health Sciences and Techniques of Sousse (SHSTS) in Tunisia and their efficacity in healthcare education compared to traditional practical examination methods.

Epidemiology of prehospital emergency calls according to patient transport decision in a middle eastern emergency care environment: Retrospective cohort-based.

Background And Aim: Though emergency medical services (EMS) respond to all types of emergency calls, they do not always result in the patient being transported to the hospital. This study aimed to explore the determinants influencing emergency call-response-based conveyance decisions in a Middle Eastern ambulance service.

Methods: This retrospective quantitative analysis of 93,712 emergency calls to the Hamad Medical Corporation Ambulance Service (HMCAS) between January 1 and May 31, 2023, obtained from the HMCAS electronic system, was analyzed to determine pertinent variables.

Mixture design of α-pinene, α-terpineol, and 1,8-cineole: A multiobjective response followed by chemometric approaches to optimize the antibacterial effect against various bacteria and antioxidant activity.

α-Pinene, α-terpineol, and 1,8-cineole are compounds naturally present in essential oils, although their amounts vary from oil to oil. Although several studies have reported their antibacterial and antioxidant effects, there are few reports on the synergistic or antagonistic effects of their combinations. The objective of this study was to investigate the combined antibacterial effect of these three compounds.

Hypertrophic obstructive cardiomyopathy with left ventricle outflow tract chordae insertion: Surgery or alcohol septal ablation? A case report.

Anomalous insertion of chordae is a rare disease that could be associated with hypertrophic obstructive cardiomyopathy (HOCM), but clinical and echocardiographic diagnoses tend to be delayed. Alcohol septal ablation has emerged as an alternative to surgical myomectomy in HOCM. When a patient showed an anomalous insertion of chordae, physicians generally opt for surgery and not alcohol septal ablation.

Auricular mucormycosis complicated by parotid abscess and facial paralysis: A very rare case report.

Mucormycosis is a serious and relatively rare invasive fungal infection. The rhino-orbito-cerebral localization is the most frequent. Other localizations have been reported including: cutaneous, pulmonary, disseminated, gastrointestinal, and miscellaneous.

Spontaneous perforation of primary gastric diffuse large B-cell lymphoma.

Primary gastric malignant lymphoma is a rare tumor. The complications associated with lymphoma are perforation, bleeding, or upper gastrointestinal stricture. While it is well known that perforations in gastric lymphoma often occurs during chemotherapy, spontaneous perforation is extremely rare in patients who did not receive chemotherapy.

Primary aortoduodenal fistula presenting as a rare cause of upper gastrointestinal bleeding.

Primary aortoduodenal fistula (ADF) is a serious life-threatening condition. Unlike secondary ADF which occurs in patients who had previous aortic prosthetic reconstruction, primary ADF is uncommon. Its diagnosis is often unsuspected until surgery or postmortem.

A ruptured balloon shaft during an angioplasty.

We report a case of balloon shaft rupture during percutaneous coronary intervention. Although the entrapped balloon was not yet deflated when the complication occurred, we successfully retrieved it percutaneously using a trapping technique. This case described a cheap and straightforward technique of device retrieval that helped save our patient.

Acute post-traumatic dermoid peritonitis: A rare entity.

Rupture of ovarian dermoid-cyst is rare case. We report the case of a woman admitted for acute post-traumatic abdominal pain due to ruptured ovarian cyst. The patient was operated and we found a very abundant peritoneal effusion with left ovarian cyst which was broken.

Peutz-Jeghers syndrome revealed by recurrent small bowel intussusceptions in children: A case report.

Peutz-Jeghers syndrome is a rare but potentially life-threating syndrome. We report here the case of a young girl who presented recurrent small bowel intussusceptions. Laparotomy exploration showed many jejunal polyps leading to jejunojejunal intussusceptions.

Actinomycosis of the middle turbinate.

Actinomycosis is an uncommon bacterial disease caused by actinomyces. Cervicofacial infection accounts for more than 60% of all cases. However, nasal and paranasal sinus involvement has rarely been described.

A massive colorectal lithobezoar in a 32-year-old woman.

A 32-year-old female patient with a history of iron deficiency and mental retardation, presented with chronic constipation and painful defecation related to a massive colorectal lithobezoar. She was successfully treated with laxatives and daily rectal enema.

Allergic contact dermatitis to isothiazolinones in a rubber factory: A case report.

Isothiazolinones, used as preservative, are known to be skin sensitizers. Although cosmetics represent their main source, occupational exposure may be a significant origin of eczema. While allergic eczema related to these derivates have been reported in a number of professional sectors, their presence in the same workplace was not common.

An uncommon case of synchronous gastric and colonic metastases from breast cancer.

Invasive lobular carcinoma is the second-most-common subtype of breast cancer. It is characterized by a different metastatic pattern with a propensity to metastasize to pleura, peritoneum, gastrointestinal tract, and ovary. We report a woman with known metastatic disease outside the gastrointestinal tract who had endoscopy and colonoscopy for gastrointestinal symptoms.

Protective effects of dietary Kefir against aflatoxin B1-induced hepatotoxicity in Nile tilapia fish, .

The effect of dietary Kefir supplementation on the biometric, biochemical, and histological parameters of Nile tilapia () exposed to aflatoxin B1 (AFB1, 200 µg/kg diet) contamination was studied. The yeasts were dominant in Kefir followed by lactic and acetic acid bacteria. The Kefir showed relatively interesting antioxidant potential in the DPPH• (IC = 0.

Design and use of chimeric peptides in a new non-destructive ecological process applied to the extraction of all trans/9-cis β-carotene isomers from .

Recently, β-carotene has gained tremendous importance as a bioactive molecule due to the growing awareness of the harmful effects of synthetic products. β-carotene is a high-value natural pigment that has the highest demand in the global carotenoid market owing to its proven antioxidant properties relevant for several diseases. To date, is the most important producer of natural β-carotene and is the subject of important industrial efforts.

An uncommon case of pancreatic adenocarcinoma revealed by dermatitis.

We report a 63-year-old-woman who presented with a pruritic rash on both thighs. Radiologic investigations revealed a pancreatic mass. Pancreatic cancer was confirmed by biopsy and the rash resolved after chemotherapy followed by pancreatoduodenectomy.

Gastric trichobezoar: An uncommon cause of epigastric pain: A case report.

Trichobezoars are foreign and indigestible materials in the gastrointestinal tract and are usually found in psychiatric females, who often deny eating their own hair, but also at situations of gastric dysmotility and prior gastric surgery. Although rare, gastric trichobezoar should not be forgotten as a differential diagnosis in females presenting with vague epigastric pain. Its treatment well in time will prevent complications.

Duplication cyst and diverticulum of the stomach: A case report of an unusual association.

Gastric duplication cysts are uncommon findings in adult patients. Accurate diagnosis of these cysts is difficult. Presenting symptoms are often non-specific, and complications are rare.
