Impact of external accreditation on students' performance: Insights from a full accreditation cycle.

Background: The process of external academic accreditation involves quality control and auditing measures that focus on the design, delivery, and outcomes of education. It is a demanding and disruptive process in terms of effort, time, money, and human resources. Nevertheless, the extent to which external quality assurance and accreditation procedures affect students' performance at the end of the learning cycle has not been well studied thus far. Methods: A retrospective quantitative secondary data analysis was conducted in The King Saud University (KSU) undergraduate medical program, with a before-after comparison research design to assess the impact of external accreditation on students' mean grade scores during an accreditation cycle. Results: Overall, the data pertaining to 1090 students who attended 32,677 examination encounters were included in the analysis. The pre- and post-accreditation analysis revealed a statistically significant improvement in the students' mean scores-80 ± 9 (pre) versus 87 ± 11 (post), with a p-value of (p = 0.003) and a Cohen's d value of 0.591. On the other hand, there was no statistically significant difference in the students' mean passing percentages-96 ± 5 (pre) versus 96 ± 9 (post), with a p-value of (p = 0.815) and a Cohen's d value of 0.043. Conclusion: The actions involved in the planning phase and the journey through the self-study evaluation not only verify the program's competencies but also functioned as critical boosters for quality improvement processes and, hence, students' learning experiences.

Conservative Management of Traumatic Brown-Séquard Syndrome: A Case Report.

BACKGROUND Traumatic spinal cord injuries are quite common; however, a rare form of incomplete spinal cord injury is Brown-Sequard syndrome. Brown-Sequard syndrome is defined by the National Institute of Neurological Disorders and Strokes as "a rare neurological condition characterized by a lesion in the spinal cord which results in weakness or paralysis (hemiparaplegia) on one side of the body and a loss of sensation (hemianesthesia) on the opposite side." CASE REPORT A 33-year-old man was brought to the Emergency Department by Saudi Red Crescent with multiple stab wounds on the left upper thoracic and lower cervical regions. He was tachycardic, but otherwise vitally stable. His Glasgow Coma Scale score was 15. The patient presented with bilateral lower limb weakness, more on the ipsilateral (left) side, and contralateral (right) hypoesthesia from the level of the nipple below. Cervical and thoracic magnetic resonance imaging revealed ligamentous injury defect at the posterior dura and indicating a dural tear with minor cerebrospinal fluid leak. Focal hyperintense signal intensity was noted on the left side of the spinal cord, representing contusion. The patient was managed conservatively with daily physical therapy. Strength had improved substantially by the time of discharge and sensation was improving. CONCLUSIONS Brown-Sequard syndrome is associated with good prognosis. These patients require a multidisciplinary approach because it provides the best chance of recovery to pre-injury status. These injuries may cause disastrous neurological deficits; therefore, preventive strategies should be designated to decrease the incidence of such injuries.

[Observational study of QuantiFERON® management for ocular tuberculosis diagnosis: Analysis of 244 consecutive tests]. / Étude observationnelle de l'usage du QuantiFERON® pour le diagnostic de tuberculose oculaire, basée sur 244 tests consécutifs.

INTRODUCTION: Ocular tuberculosis (TB) diagnosisremains difficult and quantiferon (QFT) contribution needs still yet to be specified, despite its generalization in France. The purpose of this observational study is to assess in which ocular inflammation (OI) presentation QFT is prescribed and to evaluate the added value of new QuantiFERON®-TB Gold Plus (QFT-Plus) test for diagnosis ocular TB diagnosis. PATIENTS AND METHODS: Monocentric, observational study, carried out in an ophthalmology department over a period of 5 months. Inclusion criteria were defined as an existence of an OI for which a QFT-Plus test was part of the etiological investigations. Of the 316 consecutive files, 72 were excluded (indeterminate test, prescription before anti-TNFα or immunosuppressant initiation, missing data, wrong indication) and 244 were selected and divided into two groups: group one (anterior uveitis/episcleritis, n=129) and group two (intermediate/posterior uveitis/optic neuritis/ocular myositis, n=115). All positive QFT patients underwent an etiological investigation including thoracic imaging. RESULTS: Forty-five patients, aged 52±12 years, had positive QFT (18.5%), including 18 patients for group 1 and 27 for group 2. Living in TB-endemic area, TB exposure and chest imaging abnormalities were identified in 70%, 27% and 22% of cases, respectively. OI was chronic in 36% of cases (group one, 4/18; group two, 12/27). None of the 18 patients, in group 1, received anti-tuberculosis treatment (ATT) or experienced a relapse during one-year follow-up. Four QFT+ patients, from group 2 (15%) had another associated disease explaining their uveitis. Among the 23 other patients without identified etiology, 13 had at least one relevant ophthalmological signs predictive of TB uveitis (posterior synechiae, retinal vasculitis and/or choroidal granuloma) (59%). Eleven patients received a 6-month ATT trial. Radiological abnormalities and granulomas at angiography were significantly more frequent among treated patients (p=0.03 and 0.001, respectively). A full OI recovery was observed for 8 patients (73%), considered ex-post as ocular TB. Nine patients in group 2 received rifampicin/isoniazid dual therapy for 3 months, but no conclusion could be drawn as to the benefit of such prescription on OI. QFT rate comparison, according to CD4 stimulation by ESAT-6/CFP-10 peptides or by CD4/CD8 co-stimulation, was comparable and found only 4 cases of discrepancy (1.6%). None of these 4 cases had ocular TB diagnosis. CONCLUSION: Positive QFT frequency among patients consulting for posterior OI remains high. In this study, radiological abnormalities and granulomas at angiography seemed to be more closely related to clinician decision for starting ATT trial in QFT+ patients, which was effective in 73% of cases. QFT-Plus does not seem more relevant than QFT-TB in exploring an OI. Prospective studies are necessary to codify QFT management in the etiological assessment of OI and clearly define ATT trial indications as well as their modalities.

[Cerebral infarction and tuberculosis: case report and literature review]. / Infarctus cérébral et tuberculose : rapport d'un cas et analyse de la littérature.

INTRODUCTION: Although tuberculous meningitis is an uncommon presentation of tuberculosis, it still remains one of the deadliest forms of this disease. In this context, the occurrence of a cerebral infarct is an aggravating factor. OBSERVATION: A 48-year-old Asian man presented himself in the emergency room for dysarthria and dysphagia of progressive onset. Cerebral CT showed a recent ischemic defect of the right internal capsule. Lumbar puncture showed meningitis with low sugar levels. Pulmonary micronodules on the thoracic CT suggested tuberculosis, which was confirmed by a broncho-alveolar lavage. Anti-tuberculosis treatment and early corticosteroid resulted in an improvement of the patient's state. CONCLUSION: Cerebral infarctions in patients with tuberculous meningitis are events that cannot be underestimated in terms of frequency or severity. Their poor prognosis is partly the result of insufficiently defined management, which combines anti-tuberculosis treatment and early corticosteroid therapy.

[Ocular tuberculosis]. / Tuberculose oculaire.

Despite extensive investigations, including the use of Interferon-gamma release assays (IGRA), the diagnosis of intraocular tuberculosis (TB) remains challenging. Ocular evidence of Mycobacterium tuberculosis in low endemic countries for TB is extremely rare, leading mostly to a TB-related ocular inflammation presumptive diagnosis. This present work aims: to highlights the main clinical patterns suggestive of ocular TB; and the latest recommended guidelines for diagnosing ocular TB to clarify interferon-gamma release assay (IGRA) contribution and accuracy to the management of intraocular TB and its diagnosis, in addition to other available diagnostic tools, such as tuberculin skin test, bacteriologic and histologic analysis from intra/extra ocular sample and radiographic investigations; to define the accuracy of these diagnostic tools according to the endemic TB prevalence; and finally to identify therapeutic strategies adapted to the main clinical presentations of ocular TB. Our review of the literature shows that management of suspected ocular TB differs significantly based on whether patients are from high or low TB prevalence countries since accuracy of chest X-ray, tuberculin skin test and IGRA is significantly different. Taking into account these discrepancies, distinct guidelines should be determined for managing patients with suspected ocular TB, taking into consideration home prevalence of TB-patients.

[Therapeutic strategy for the treatment of non-infectious uveitis proposed by an expert panel]. / Avis d'experts pour le traitement des uvéites non infectieuses.

Conventional immunosuppressive drugs, anti-TNF alpha and other biotherapies used in clinical practice are capable of controlling non-infectious anterior uveitis, posterior uveitis and panuveitis. The present work has been led by a multidisciplinary panel of experts, internists, rheumatologists and ophthalmologists and is based on a review of the literature. In case of corticodependency or sight-threatening disease, conventional immunosuppressive drugs (methotrexate, azathioprine and mycophenolate mofetil) and/or anti-TNF alpha (adalimumab, infliximab) are used to achieve and maintain remission. Interferon is an efficient immunomodulatory treatment, as a second-line therapy, for some therapeutic indications (refractory macular edema, Behçet's vascularitis). Other biologics, especially tocilizumab, are showing promising results. Local treatments (corticosteroids, sirolimus etc.) are adjuvant therapies in case of unilateral inflammatory relapse. Therapeutic response must be evaluated precisely by clinical examination and repeated complementary investigations (laser flare photometry, multimodal imaging, perimetry, electroretinography measures).

[Induced drug uveitis and drug side effects in ophthalmology]. / Uvéite médicamenteuse et effets indésirables des médicaments en ophtalmologie.

Ocular drug side effects are very varied and can affect all the structures of the eye. The purpose of this review is to help clinicians: (i) to evoke this drug-induced toxicity yearly in the course of an unexplained ocular injury, before its damage become irreversible, (ii) to be able to recognize induced paradoxical ocular inflammation, mimicking an inflammatory pathology flare-up, especially in patient under anti-TNF regimen and (iii) to propose a more in-depth knowledge on recently described ocular toxicities from targeted cancer therapy, mainly the tyrosine kinase inhibitors.

[Scleritis and systemic diseases: What should know the internist?] / Sclérites et maladies systémiques : que doit savoir l'interniste ?

Scleritis is an inflammatory disease of the sclera; outer tunic of the eye on which the oculomotor muscles are inserted. It can be associated with a systemic disease up to one time out of 3. These associated diseases are mainly rheumatoid arthritis, vasculitis, including granulomatosis with polyangiitis in the first line and spondyloarthropathies. Before mentioning such an etiology, it is necessary to eliminate an infectious cause, mainly herpetic, which is regularly underestimated. The classification of scleritis is clinical. We distinguish between anterior scleritis and posterior scleritis. Anterior scleritis is diffuse or nodular, usually of good prognosis. Anterior necrotizing scleritis with inflammation is often associated with an autoimmune disease, necrotizing scleritis without inflammation usually reflects advanced rheumatoid arthritis. The treatment of these conditions requires close collaboration between internists and ophthalmologists to decide on the use of corticosteroid therapy with or without immunosuppressors or biotherapies.

[Management of orbital inflammation in internal medicine. Proposal for a diagnostic work-up]. / Orbitopathies inflammatoires. Que doit savoir l'interniste ?

Inflammatory orbitopathies relate to an inflammatory state originating within the orbit and its adnexes, except the inner ocular globe. Orbital inflammation (OI) may be either localized manifestation of a proven or like autoimmune disease, or local response from immune system against infectious, structural or tumoral antigens. We review the clinical manifestations of OI, which provide helpful clues to the diagnosis and describe the inflammatory, infectious and neoplastic conditions classically associated with OI. Autoimmune diseases are probably the most common causes of OI associated with a bilateral dacryoadenitis (e.g., sarcoidosis, granulomatosis with polyangiitis, IgG4-related disease). We focused on a major part of the IgG4-RD spectrum, the IgG4-related orbital disease which has been recently described and the idiopathic orbital inflammation syndrome that one should consider in patients 40 years of age or older with non specific inflammation OI on biopsy but without underlying local or systemic disease. An algorithm for the diagnostic approach of OI was proposed. If systemic explorations fail to diagnose an underlying disease, histopathologic control is required for distinguishing non-specific OI from other differential diagnosis, especially lymphoma. In the cases of pure myositic locations and posteriorly located tumours where biopsy could damage to the optic nerve, analysis of orbital lesions in T2W IRM sequence may be helpful to distinguish idiopathic OI (IOI) from lymphoma. When the diagnostic work-up fails, a corticosteroid trial could be used, but its beneficial effect has to be cautiously interpretated before definitively diagnosing IOI. Finally, treatments used in main infllammatory orbitopathies were also reviewed.

[Uveitis: Diagnostic work-up. Recommendations from an expert committee]. / Prise en charge diagnostique des uvéites : recommandations d'un groupe d'experts.

INTRODUCTION: Diagnostic work-up of uveitis involves many uncertainties. Search for an etiology should take into account the epidemiology of uveitis and focus on the most severe diseases or those, which can be treated. This work was undertaken to establish recommendations for the diagnosis work-up of uveitis. METHODS: Recommendations were developed by a multidisciplinary panel of 15 experts, including internists, ophthalmologists and a rheumatologist and are based on a review of the literature with regard to effectiveness of investigations and the results of the ULISSE study, which is the first prospective study assessing the efficiency of a standardized strategy for the etiological diagnosis of uveitis. Children, immunocompromised patients, severe retinal vasculitis and specific ophthalmological entities are excluded from these recommendations. RESULTS: Investigations should be first guided by the history and physical examination. Serological screening for syphilis is the only test appropriate in all forms of uveitis. If no diagnosis is made after this stage, we propose investigations guided by the anatomic characteristics of uveitis. It includes HLA B27 testing (in unilateral acute anterior non-granulomatous uveitis), serum angiotensin converting enzyme, interferon-gamma release assay and chest CT (chronic uveitis), cerebral MRI and anterior chamber tap with IL10 analysis (intermediate or posterior uveitis in patients over 40 years). Investigations ordered in the absence of orientation are almost always unhelpful. CONCLUSIONS: We propose a strategy for the etiologic diagnosis of uveitis. The recommendations should be updated regularly. The efficiency of more invasive investigations has yet to be evaluated.

Update on Immunological Test (Quantiferon-TB Gold) Contribution in the Management of Tuberculosis-Related Ocular Inflammation.

PURPOSE: To clarify interferon-gamma release assay (IGRA) contributions to intraocular tuberculosis management, according to related TB endemic prevalence. METHODS: Despite extensive investigations, including IGRA, the diagnosis of intraocular tuberculosis (TB) is still challenging and remains mostly presumptive. According to the literature, it appears that management of suspected ocular TB differs significantly based on whether patients are from areas of high TB prevalence or from non-TB-endemic countries. The accuracy and final contribution of chest X-rays, tuberculin skin test and IGRA differ significantly according to low or high endemic TB areas. This work aims to review IGRA test outcomes in the light of these clinical and epidemiological settings. We therefore focused our analysis and its subsequent guidelines proposal based on the TB prevalence where the patient lives. CONCLUSION: We believe that distinct guidelines should be determined for managing patients with suspected ocular TB, first taking into consideration the relative TB prevalence.

[Diagnostic issues of lymphogranuloma venereum: A case series of 5 patients]. / Diagnostic de la lymphogranulomatose vénérienne : à propos d'une série de 5 cas.

INTRODUCTION: Lymphogranuloma venereum (LG) is a sexually transmitted infection (STI) caused by Chlamydia trachomatis L serovar. METHODS: These five consecutive cases aim to highlight the risk of LG misdiagnosis, in case of initial presentation with isolated inguinal adenitis. RESULTS: Five men (mean age: 30±7 years) were seen in an internal medicine department, for inguinal adenopathy. One patient had clinical signs of urethritis. None presented an associated rectitis. Three patients had a history of STI, and two had a discovery of related HIV disease. Urinary polymerase chain reaction (PCR) was positive for the symptomatic patient and negative for the others. Lymph node PCR was positive in all patients within a L2b serotype (searched in 4 out of 5 cases). CONCLUSION: LG should be evoked in any patient with inguinal adenomegaly, particularly in case of STI history or risk factors. Negativity of urinary PCR should lead to further investigations, essentially a lymph node cytopuncture to evidence C. trachomatis.

[Management of uveomeningitis in internal medicine: Proposal for a diagnostic work-up]. / Prise en charge diagnostique des uvéoméningites en médecine interne.

Uveomeningitis relates to an inflammatory state extending from iris and ciliary bodies to the choroid behind the eye. Because of a close contact between eye and brain, and barrier disruption, the inflammation can spread into the central nervous system (CNS). We review the clinical manifestations of uveitis, which are known to provide helpful clues to the diagnosis and describe the infectious, inflammatory, and neoplastic conditions classically associated with the uveomeningitis. Inflammatory or auto-immune diseases are probably the most common clinically recognized causes of uveomeningitis associated with a significant pleiocytosis. These entities often cause inflammation of various tissues in the body, including ocular structures and the meninges (i.e., sarcoidosis, Behçet's disease, and Vogt-Koyanagi-Harada syndrome). The association of an infectious uveitis with an acute or a chronic meningo-encephalitis is unusual but occasionally the eye examination may suggest an infectious etiology or even a specific organism responsible for an uveomeningitis. One should consider the diagnosis of primary ocular-CNS lymphoma in patients of 40 years of age or older with bilateral uveitis, especially with prominent vitritis, showing poor response to corticosteroid therapy. Finally, an algorithm for the diagnostic approach of uveomeningitis is proposed.

Biotherapies in inflammatory ocular disorders: Interferons, immunoglobulins, monoclonal antibodies.

Biotherapies used in clinical practice for the treatment of ophthalmologic manifestations of systemic diseases include interferons (IFN), intravenous immunoglobulins (IVIG) and monoclonal antibodies (anti-TNF, anakinra, tocilizumab and rituximab). Several open prospective studies have shown the effectiveness of IFN-α (78 to 98% complete remission) for the treatment of severe uveitis in Behcet's disease. IFN is capable of inducing prolonged remission and continued after his arrest, in 20-40% of patients. Side effects (flu-like, psychological effects) limit its use in practice. Anti-TNFα (infliximab and adalimumab) represents an attractive alternative therapeutic in severe uveitis refractory to immunosuppressants, especially in Behcet's disease. They are almost always (>90% of cases) and rapidly effective but their action is often suspensive. Anti-TNFα requires an extended prescription or takes over from another immunosuppressant once ocular inflammation has been controlled. IVIG are used for the treatment of Kawasaki disease and Birdshot disease. Several open or retrospective studies showed their effectiveness for the treatment of severe and refractory cicatricial pemphigoid. Tolerance of IVIG is good but their efficacy is transient. Rituximab showed an efficacy in few observations of various inflammatory eye diseases (uveitis, scleritis and idiopathic inflammatory pseudo-tumors or associated with granulomatosis with polyangiitis) and cicatricial pemphigoid. The risk of infection associated with this biotherapy limits its use in refractory diseases to conventional therapy. Anakinra (a soluble antagonist of IL-1R) showed interesting results in terms of efficiency in one small open study in Behcet's disease. Its safety profile is good and with a quick action that could be interesting for the treatment of severe uveitis.
