The impact of the herd health interventions in small ruminants in low input production systems in Ethiopia.

Introduction: Diseases have a negative impact on production and profitability of small ruminants. A good herd health program can decrease the number of sick animals and improve herd performance.

Methods: In a longitudinal study, small ruminant herd health interventions such as community-based strategic gastrointestinal (GI) parasite control, prevention and control of major respiratory diseases and capacity development activities were implemented.

Response of maiden ewes to the 'ram effect' is a robust management practice and a candidate selection trait for enhanced reproductive performance in drylands.

Management of reproduction that relies on naturally based solutions is extremely important to counter the negative perception around hormone-based interventions. In Mediterranean latitudes and wider regions of non-tropical drylands, sheep do not normally ovulate during spring but exposure to a ram can induce oestrus and ovulation. This study assesses the response of maiden Barbarine ewes in drylands to the 'ram effect' during springtime and estimates the genetic parameters of this response.

Evaluation of nerve fiber layer and ganglion cell complex changes in patients with migraine using optical coherence tomography.

Purpose: To analyze changes in peripapillary retinal nerve fiber layer (RNFL) and ganglion cell complex (GCC) thickness in migraine patients with and without aura compared to healthy controls and to identify factors influencing the occurrence of these anomalies.

Methods: This is a cross-sectional case-control study including migraine patients and control subjects. All patients and controls underwent a complete ophthalmological examination, RNFL and GCC thickness measurements using a spectral domain-OCT device.

Spitzoid melanoma of the finger: a case report.

Background: Melanoma is the most malignant skin tumor, with a high metastatic potential. Spitzoid melanoma is a subtype of melanoma requiring rapid management and extensive tumor resection. We have set the goal to recognize anatomical peculiarities and difficulties diagnoses posed by this type of tumor, as well as to recognize the management modalities, especially the surgical one, of malignant spitzoid melanoma.

Prevalence of Fasciola hepatica infection in slaughtered sheep from Northwest Tunisia and its risk factors: Association with gastrointestinal helminths infection and anaemia.

We investigated herein the prevalence of Fasciola hepatica infection in sheep at Sejnane slaughterhouse, governorate of Bizerte, Northwest of Tunisia, using three different diagnostic techniques (liver dissection, bile examination, and coprology). Faeces, liver, gall bladder as well as blood samples were collected from 603 slaughtered sheep in two seasons: winter and summer. Faecal egg counts of F.

Evaluation of retinal perfusion density and foveal avascular zone in migraine subjects with and without aura.

Migraine, classified as a neurovascular disease, has been identified as a potential risk factor for ocular vascular complications. Our study aimed to compare retinal vessel density and perfusion density between subjects with migraine and healthy subjects using optical coherence tomography angiography (OCTA). In this cross-sectional case-control study, we enrolled 30 migraine subjects with aura (MWA), 30 migraine subjects without aura (MWOA) and 30 age and gender-matched healthy controls (HC).

Preoperative anxiety and postoperative pain associated with cataract surgery under local anesthesia.

Introduction: Although cataract surgery is a routine outpatient surgery, anxiety and pain remain two significant concerns seen in patients.

Aim: To describe preoperative anxiety and postoperative pain related to cataract surgery under local anesthesia and identify the factors determining their occurrence.

Methods: This is a cross-sectional, descriptive and analytical, study which included patients who underwent cataract surgery for the first eye in the ophthalmology department of Habib Bourguiba University Hospital in Sfax-Tunisia.

Repeated Cross-Sectional Survey of Ectoparasites in Sheep from Central Tunisia: Does Low Prevalence Indicate Good Hygiene or Resistance to Ectoparasites?

Sheep ectoparasites such as chewing lice, fleas and ticks are serious constraints to sheep productivity and are the cause of skin lesions in animals that decrease their market value. This study aims at investigating the ectoparasite fauna infesting small ruminants in the district of Sidi Bouzid (central Tunisia). A total of 1243 Barbarine and Queue Fine de l'Ouest (QFO) sheep were examined every two months for one year.

A rare ocular manifestation of mycoplasma pneumoniae infection.

Introduction: Ocular manifestations of Mycoplasma Pneumoniae infection are rare. We present a case of Mycoplasma Pneumoniae infection revealed by a recurrent retro-bulbar optic neuritis.

Case Description: A 38-year-old woman, initially treated for a typical retro-bulbar optic neuritis of the right eye with corticosteroid therapy at high doses, presented for a recurrent decreased vision in the same eye, associated with blepharospasm and conjunctival hyperemia.

Clinical and therapeutic characteristics of childhood uveitis in a tertiary center in Tunisia.

Introduction: Childhood uveitis is a rare condition with various associated diagnostic and therapeutic challenges.

Aim: We proposed to describe the distribution, clinical findings, treatment, complications, and visual outcomes of uveitis in children at a tertiary referral center in Sfax, Tunisia.

Genetic diversity of Hyalomma marginatum in Tunisia is not influenced by the bio-climate.

Ticks are important ectoparasites responsible for the transmission of several pathogens with significant medical, veterinary, and economic impacts. Climate and social changes have generated substantial changes in ticks' distribution, abundance, and activity patterns, including ticks belonging to the Hyalomma marginatum species. Knowledge on the genetic structure and dynamics of H.

Conservation agriculture has no significant impact on sheep digestive parasitism.

Conservation agriculture (CONS A) is a sustainable agriculture system based on crop rotation with no tillage. It has various environmental advantages compared to conventional agriculture (CONV A): decreased water evaporation, erosion, and CO emissions. In this first study of its kind, we aim to evaluate the impact of this type of agriculture on sheep gastrointestinal parasites.
