Pseudo-angiomatous hyperplasia of mammary stroma: a case with gigantomastia

Pseudo-angiomatous hyperplasia of mammary stroma (PASH) is a histopathological entity which is a microscopic fortuitous finding in mammary biopsies performed for different reasons. It may be symptomatic and appears then as a palpable lump. The term pseudo-angiomatous emphasizes the characteristic aspect of the stroma simulating a vascular tumor. We report a case of PASH in a 71 year-old woman who presented a recurring breast mass with rapid swelling of the mammary gland (70 x 60 x 20 cm) treated by mastectomy. PASH must be distinguished from a well-differentiated angiosarcoma. It is ruled out by immunohistochemistry.     

Effect of profenofos feeding on biochemical changes in chicken

The disruption of transaminases and phosphatases from the normal values denotes biochemical impairment and lesions of tissues and cellular function because they are involved in the detoxification process, metabolism and biosynthesis of energetic macromolecules for different essential function. The results of the present study revealed that feeding chicken in profenofos contaminated feed at levels of 50, 100 and 200 ppm for three weeks, resulted in a significant increase in the values of glutamic-pyruvic transaminase (GPT), glutamic oxaloacetic transaminase (GOT), Alkaline phosphatase (A.P.) and cholesterol, especially at levels of 100 and 200 ppm. Upon return of normal feed free from profenofos for 10 days, these values decreased gradually but not to normal and the decreases were not significant.     

A case study about the use of the prospective strategy in the scenarization of a pedagogical workshop

IntroductionPedagogical workshop planning is challenging especially when we aim to promote a reflective practice of the tutees. This practice has been widely discussed in the literature without a real consensus. Some authors reported oral exercises or anecdotes, other described writings or even storytelling. The aim of the authors was to describe the different steps performed by the tutors and to assess the tutees’ satisfaction.Material and methodsThis was a pilot study dealing with the use of the prospective strategy principles in order to plan a pedagogical workshop. Included participants were early academic teacher trainees.ResultsThe authors illustrated how they planned a pedagogical workshop using the prospective strategy and highlighted the satisfaction of the tutees.ConclusionProspective strategy is mainly used in economic field in order to change the future of the companies by acting on different intervening factors. Associating prospective strategy to pedagogical principles hasn’t been reported in the medical literature and seems to be available in order to induce reflective practice.     

Spondyloarthritis in North Africa: an update

Clinical Rheumatology - Spondyloarthritis (SpA) has been less well studied than rheumatoid arthritis in North Africa, due to a belief that it is rare and benign in certain populations. The main...     

Does isolated myocardial bridge really interfere with coronary blood flow?

BackgroundMyocardial bridge (MB) is defined as a segment of a major epicardial coronary artery the “tunneled artery” that goes intramurally through the myocardium beneath the muscle bridge. Multiple methods have been proposed to assess coronary flow rate among which thrombolysis in acute myocardial infarction frame count was a relatively new semiquantitative method.ObjectivesOur goal was to determine incidence of MB in the patients undergoing coronary angiography in Mansoura Specialized Hospital, Cardiac Catheterization Laboratory, also to investigate the hypothesis that slow coronary flow rate may be linked to angina or angina like symptoms in patients with MB without stenotic lesions in epicardial coronary arteries using TFC.Patients and methodsFifteen patients with MB (group I) were retrospectively collected from Mansoura Specialized Hospital, Cardiac Catheterization Laboratory, we review 3000 cases referred to diagnostic coronary angiography to exclude significant coronary artery disease. Fifteen patients with normal coronary angiography served as control (group II). We review the clinical presentations, risk factors, echocardiographic data for both test and control groups. TFC was calculated using a simple continuous index.ResultsThe incidence of MB in our study was 0.5%. CTFC in LAD was significantly higher in the patients with MB compared with control. No significant correlation between TFC and echocardiographic parameters.ConclusionsMyocardial bridging must be considered especially in patients at low risk for coronary atherosclerosis but with angina like chest pain or established myocardial ischemia. We suggest that coronary blood flow is decreased in the patients with MB compared with the patients having normal coronary.     

Shear wave elastography of lumbar annulus fibrosus in adolescent idiopathic scoliosis before and after surgical intervention

To determine lumbar intervertebral disc properties with shear wave elastography in adolescent idiopathic scoliotic (AIS) patients before and after surgery, and compare them with asymptomatic controls. Twenty-five severe AIS patients with an indication for fusion surgery (15 ± 1.5 years old, the Cobb angle ranging between 40 and 93°) and fifty-nine asymptomatic adolescents (13 ± 2 years old) were included prospectively. Shear wave speed (SWS) was measured in the annulus fibrosus of L3-L4, L4-L5, and L5-S1 discs of each subject. In AIS patients, measurements took place before surgery, and 3 months (N = 13) or 1 year after (N = 12). No difference was observed between disc levels in any group. When pooling disc levels, SWS was significantly higher in preop AIS patients (4.0 ± 0.5 m/s) than in asymptomatic subjects (3.1 ± 0.5 m/s, p < 0.0001). SWS decreased 3 months postop (3.5 ± 0.3 m/s), and it decreased further towards normal values 1 year after (3.3 ± 0.4 m/s). SWS in preop AIS patients tended to decrease with the Cobb angle (Spearman’s rho = − 0.4, p = 0.05). Shear wave elastography measurements showed that discs in AIS patients were altered relative to asymptomatic ones, and this alteration tended to normalize 1 year post fusion surgery. Further studies should aim at determining if bracing of mild scoliosis has an effect on disc properties. • Shear wave elastography shows alteration of annulus fibrosus in adolescent idiopathic scoliosis. • Disc elastography tends to normalize 1 year after surgery.     

Complications in paediatric liver transplant from Kuwait when transplanted abroad

Background and study aimsSince the introduction of liver transplantation (LTx) in children suffering from liver failure in 1963, many centres around the world have offered this service to children that have no other alternative. The aim of this retrospective study is to analyse the results of paediatric liver transplant in Kuwait over the last decade.Patients and methodsA retrospective chart review was done involving paediatric patients during the time period of 1995–2004. The information collected included patient demographics, indications for liver transplantation, survival of both patient and allograft, and complications.ResultsA total of 16 cases were found and analysed. The mean age was 3.6 years (ranged 5 months–17 years). There were nine boys and seven girls. The most common indications for LTx were biliary atresia and metabolic liver disease. All the liver transplants were done abroad. There were totally nine deceased donor and seven living related cases. The complications were acute cellular rejection in five, hypertension in two, biliary complications in four, cytomegalovirus (CMV) infection in three and post lymphoproliferative disease in two cases. All but one patient are presently alive.ConclusionThe above information demonstrates that LTx in Kuwati children is safe and improves the quality of life for those that would otherwise have no other alternative.     

Nivolumab as adjuvant treatment for a spinal melanocytoma: A case report

Rationale:Meningeal melanocytoma is a rare benign melanocytic tumor of the central nervous system. We report for the first time a case of meningeal melanocytoma treated with immunotherapy.Patient concerns:A 70-year-old man with no medical history was admitted to the Emergency Room. He suffered from a motor and sensory deficit in his left lower limb and a bilateral upper arm neuralgia.Diagnoses:A contrast-enhanced magnetic resonance imaging (MRI) was performed. It showed a C7-T1 bleeding intramedullary tumor. Laminectomy was decided and performed. The results of the pathologic examination showed a melanocytic tumor harboring GNAQ mutation. Meningeal melanocytoma was the final diagnosis.Interventions:The patient was treated with 10 radiotherapy sessions and 6 cycles of nivolumab. A year later, the patient experienced neuralgia again with severe pain and an increasing sensory motor deficit. He underwent a second surgery that was incomplete. As the tumor kept growing, he received temozolomide. But the 6th cycle had to be interrupted due to bedsore infection in the hip area.Outcomes:Disease progression finally led to the patient''s death 3 years after diagnosis.Lessons:This case report is the first about a patient with meningeal melanocytoma treated with immunotherapy. Treatment based on biomolecular mutations will probably change spinal melanocytoma therapeutic approach in the next few years.
