Abstract
Mitofusin-1 is one of the membrane profusion proteins that is present in the mitochondria wall. It has a role in mitochondrial fusion. Deletion of mitochondrial fusion proteins in oocytes leads to dynamic defects in mitochondria. Growth of implanted and after implantation embryo is an ATP-demanding step that involves a range of ATP-consuming events that require a small amount of ATP. The study aims to evaluate the mitofusin-1 in the serum and follicular fluid as a marker for the evaluation of embryo quality, in addition to the pregnancy rate in infertile females undergoing ICSI cycles. The cross-section study included 50 infertile couples who were prospectively recruited according to specific criteria at the" High Institute for Infertility Diagnosis and Assisted Reproductive Technologies" at AL-Nahrain University for one year. all participants have undergone oocyte pickup, ICSI, and embryo transfer. Mitofusin-1 levels were measured in serum on day 2 of the cycle and in follicular fluid on the day of ova pick-up. Showed important positive relations between follicular fluids mitofusin-1 with a total number of embryos (r=0.428 & p=0.002), GI embryos (r=0.335 & p=0.017) and GII embryos (r=0.295 & p=0.038). Out of 50 females, 14 (28.0 %) females became pregnant according to the results there were significantly higher follicular fluids mitofusin-1 levels in pregnant females (3.88±1.41 vs. 2.73±1.24 & p=0.007) compared to non-pregnant group. Also, the follicular fluids mitofusin-1 cut-off value was ≥2.89 ng/ml with sensitivity=71.4%, specificity=66.7%, positive predictive value 47.8%, negative predictive value 88.9%. Elevated MEN1 levels in the follicular fluid may affect positively IVF/ICSI outcomes (embryo quality, and pregnancy rate).

Abstract
Laparoscopic cholecystectomy is the standard of care for the surgical management of symptomatic gallstone disease. Gallstone spillage at laparoscopic cholecystectomy is common, with a reported incidence of 0.2-20%. In the majority of cases there are no complications associated with this spillage, but a series of studies report patients with complications of free peritoneal gallstones. We present a case of migration of gallstone to the lung resulting in an inflammatory mass in the right middle lobe as a complication of spillage at laparoscopic cholecystectomy.

Abstract
We describe a case harboring a homozygous CYP24A1 mutation with mild loss of function, first presenting with recurrent nephrolithiasis from the age of 22 onward, initially associated with hypercalcemia and low PTH concentrations. Over the years, hyperparathyroidism developed, resulting in more severe hypercalcemia. Also, kidney function deteriorated, most probably as a consequence of biopsy-proven nephrocalcinosis. Conventional treatment options for CYP24A1 mutation were not effective and/or tolerated (avoidance of sun exposure, diet, pamidronate, itraconazole). A total parathyroidectomy was performed resulting in a normocalcemic hypoparathyroidism without need for treatment with vitamin D analogs, a positive bone mineral balance and an improved kidney function.

Abstract
INTRODUCTION COVID-19 pneumonia presented a unique problem for healthcare systems with the potential to overwhelm hospitals and lead to unnecessary morbidity and mortality. Safe triage and follow up systems are required to manage this unprecedented demand. METHODS We designed a pathway for the triage and assessment of patients based on their resting oxygen saturations and response to a 30 metre rapid walking test. We admitted patients to a 'Virtual Ward' for remote oximetry monitoring from the Emergency Department, step down from inpatient wards and from the local Primary Care 'Hot Hub'. This allowed the safe and managed readmission of those patients who deteriorated at home. RESULTS During the first wave of COVID-19 we entered 273 onto the pathway for Virtual Ward follow up. Of these, 31 patients were readmitted to hospital, two were admitted to Intensive Care and one patient died. Median oxygen saturation at presentation was 97 % (IQR 96-98%) and following a 30 metre walk test 96% (IQR 94-97%). Median NEWS-2 score was 2 (IQR 1-3). On feedback 99.5% of patients were likely or extremely likely to recommend the service to their family and friends. There was a cost avoidance of £107,600 per month. CONCLUSION It is safe, feasible and cost effective to set up a triage system with remote oximetry monitoring for patients with COVID-19 and overwhelmingly patients find it a positive experience.

Abstract
Thirty-five patients diagnosed to have ovarian cancer (early FIGO stage I/II n = 11, advanced FIGO stage III/IV, n = 24) were evaluated for hemostatic parameters relating to survival outcome by 36 months of disease. Systemic plasminogen activators and inhibitors were evaluated and we found no significant association with survival outcome and eventually only fibrinogen, von Willebrand Factor (vWF), antithrombin III (ATIII), and D-dimer levels were determined for their association with disease outcome by 12 months, 24 months, and 36 months. Twenty-four patients succumbed to the disease by 36 months (early n = 2, advanced n = 22). The 11 surviving patients (advanced n = 3, including one deceased at 52 months) is still living past 36 months and 82 months at the time of analysis. Elevated fibrinogen, vWF, and D-dimer together with reduced ATIII levels were found to be associated with poor survival outcome by 12 months of disease. Moreover, elevated vWF and D-dimer with reduced ATIII levels was strongly implicated with poor survival outcome by 36 months from ovarian cancer. The overall survival rate at 36 months from ovarian cancer was 31.4%. It is therefore suggested that fibrinogen, vWF, ATIII, and D-dimer levels be used together as prognostic markers for disease outcome especially in patients with advanced ovarian cancer within 36 months of disease. An expanded study is required to confirm these findings.

Abstract
The aim of this study was to determine the frequency and determinants of sharps injuries among private health practitioners in slum areas of Karachi, Pakistan. All practitioners with at least 1 year of experience in a private medical clinic were asked to complete a self-administered, structured questionnaire (317/397 responded). Only 7.9% of practitioners were qualified from medical school, 12.3% were registered nurses and 8.8% lacked any professional qualifications. At least 1 sharps injury in the previous 12 months was reported by 26.7%, mostly due to needle recapping. Only 25.2% reported using a new syringe for each patient. In multivariate regression analysis shorter work experience, < 14 years of schooling, > 20 patients per day, administering > or = 30 injections per day, reuse of syringes and needle recapping after use were significantly associated with sharps injury in the past year. Better awareness and training on standard precautions is needed for private practitioners in slum areas of Karachi.

The ureter phantom consisted of a water box (14 cm x 32 cm x 42 cm) with five parallel plastic tubes (diameter 2.7 mm) filled with different concentrations of contrast media (1.88-30 mg iodine/ml). CT density of the tubes and noise of the surrounding water were determined using two multidetector scanners (Philips MX8000 with four rows, Siemens Sensation 16 with 16 rows) with varying tube current-time product (15-100 mAs per slice), voltage (90 kV, 100 kV, 120 kV), pitch (0.875-1.75), and slice thickness (1 mm, 2 mm, 3.2 mm). Contrast-to-noise ratio as a parameter of image quality was correlated with dose (CTDI) and was compared with image evaluation by two radiologists. The CT densities of different concentrations of contrast media and contrast-to-noise ratio were significantly higher when low voltages (90 kV versus 120 kV, 100 kV versus 120 kV) were applied. Smaller slice thickness (1 mm versus 2 mm) did not change CT density but decreased contrast-to-noise ratio due to increased noise. Contrast phantom studies showed favourable effects of low tube voltage on image quality in the low dose range. This may facilitate substantial dose reduction in CT urography.

Abstract
The study involved 196 participants, 83 (42.3%) of which were consultants and 113 (57.7%) were General Practitioners (GP's).
Background: The way that GP's and hospital consultants or specialists interact has important implications for any health care system in which a GP is the first contact health professional person for patients and the point of access to relatively scarce and expensive hospital services, for this reason, the relationship between the two main branches of the medical profession has received a considerable amount of interest.
Objectives: To test out some professional issues on a random sample of both parties to determine their ability to work together productively.
Methods: We conducted a lickert-style survey based upon statements made in qualitative questionnaire sent to GP's and specialists working at Hamad Medical Corporation and health centers in state of Qatar. The questionnaire was modified and validated during a multistage pilot and was distributed to a stratified random sample of 196 clinicians.
Results: GP's and consultants demonstrated a good level of agreement, mutual understanding and respect (Significant difference in opinion only in four statements out of 13).
Conclusion: The ability of GP's and specialists to work together has been tested out and confirmed with acceptable significance and it may be repeated to assess the relationship which is central to an efficient and effective operation of health care delivery.

Abstract
UNLABELLED A large body of evidence suggests the existence of functionally polarized human T-helper responses based on their profile of cytokine secretion. Human T-helper cell clones can be divided into two mutually exclusive subsets, T-helper cell 1 (Th1) and T-helper cell 2 (Th2). Substantial work in several animal models has demonstrated that allograft rejection is associated with enhanced Th1 activity and tolerance with enhanced Th2. Some studies have not been consistent with this association. In this study, gamma interferon (INF-y) and interleukin 4 (IL-4) levels (as indicators of Th1 and Th2 activity, respectively) were assayed in supernatant of cultured peripheral lymphocytes. The levels of these cytokines were compared between a study group of 26 stable kidney transplant recipients immunosuppressed with cyclosporine A, corticosteroids and azathioprine or mycophenolate mofetil, and a control group of 10 healthy blood donors. The mean INF-gamma and IL-4 levels in the control group were considered as the cutoff levels for comparison. Our results showed that 25/26 of the study patients (96%) had low levels of INF-gamma compared to 4/10 of the control subjects (40%), (P< 0.05). However, the IL-4 level was high in 10/26 of the study patients (38%) and 3/10 of the control subjects (30%), not a statistically significant difference, (P>0.05). IN CONCLUSION These results suggest that well-established graft tolerance may be mediated via depressed Th1 activity rather than enhanced Th2 activity.

Abstract
Human brains present a clear asymmetry of the postero-lateral cortical area, so called "planum temporale" (Geschwind and Levitsky). This asymmetry is on favour of the left brain. A similar asymmetry is observed on the parietal operculum. MRI studies of 37 healthy volunteers have shown a clear difference between individuals. Mixing the index of temporal and parietal asymmetry, the authors consider four types: the most frequent pattern concerns 90% of right handed. For the others, 10% there are left handed as right handed. On conclusion, planum as many asymmetry and opercular asymmetry can be divergent, and both canan to determines handedness.

Abstract
OBJECTIVE In Lebanon there is very limited restriction on drug use. Accordingly, self-medication is highly prevalent. This study examined the influence of these factors on the development of drug-related illnesses that lead to hospitalization. METHODS Patients admitted to the medical and pediatric wards of a tertiary teaching center in Beirut, Lebanon, over a period of 6 months were interviewed and their charts were reviewed. Admissions attributable to adverse drug reactions or therapeutic failures were identified and characterized with respect to demographic factors, medical history, drug intake, and self-medicating behavior. The influence of these variables on the development of drug-related illnesses was examined by logistic regression. RESULTS Of 1745 adults and 457 children, there were 177 (10.2%) and 36 (7.9%) drug-related illnesses, respectively. Adverse drug reactions accounted for 7.0% and 5.7% and therapeutic failures for 3.2% and 2.2% of adult and pediatric admissions, respectively. Self-medication was commonly practiced (52.6% of adults and 41.6% of children). Logistic regression analysis revealed that female sex increased the risk of adverse drug reaction in adults, whereas self-medication decreased the risk. In children, the risk of adverse drug reaction was increased in lower socioeconomic groups, whereas the risk of therapeutic failure was increased by a positive history of atopy or drug reaction. CONCLUSIONS These results provide the first detailed analysis of the problem of drug-related illnesses in a developing country and identify a number of related or risk factors. Despite the lack of regulation of drug dispensing and the unchecked access to drugs in Lebanon, the incidence of drug-related illnesses is not different from that in Western nations. This finding may have relevance to policies of drug regulation in other countries.

Abstract
Pregnancy is thought to have an ameliorating effect on endometriosis, inducing a state of quiescence. We report a case of ruptured endometriotic cyst in pregnancy successfully treated by laparoscopic ovarian cystectomy. Our patient subsequently progressed uneventfully to deliver a healthy baby girl at term. Laparoscopic ovarian cystectomy in pregnancy, even with ruptured cysts, appeared to be safe in trained hands with similar benefits of reduced post-operative morbidity.

Abstract
The risk of progression to multiple sclerosis (MS) after an episode of acute non compressive episode involving the spinal cord remains uncertain. A follow-up study was performed to determine the risk of early progression to MS in 20 patients presenting with clinically isolated lesions of the spinal cord, combined clinical evaluation, spinal and brain magnetic resonance imaging (MRI), visual, brainstem auditory and somatosensory evoked potentials (VEPs, BAEPs, SEPs), and cerebrospinal fluid (CSF) electrophoresis analysis. Spinal cord MRI demonstrated more lesions in cervical region (74 p. 100) than thoracic or lumbar regions (26 p. 100). Six patients (30 p. 100) had an initial brain MRI that was strongly suggestive of MS and 5 patients (25 p. 100) had only one MS-like abnormality. Eight patients (40 p. 100) had abnormal VEPs, 3 (15 p. 100) abnormal BAEPSs and only 44 p. 100 (8/18) abnormal SEPs. In contrast, CSF analysis showed oligoclonal bands (CSFOB) in 15/19 patients (79 p. 100). The diagnosis of MS was performed initially in 13 cases (65 p. 100) (clinically definite MS (CDMS) in 30 p. 100, laboratory-supported definite MS (LSDMS) in 61 p. 100 and clinically probable (CPMS) in one case). During the follow-up period (18 +/- 7 months), 8 patients (40 p. 100) presented one or more exacerbations and time to the first recurrence was 8 +/- 5 months. Seven of these 8 patients were initially treated by infusion of methylprednisolone. Among these patients, all of them had CSF OB and initial brain MRI was strongly suggestive of MS in 3 of them. During this follow-up period, brain MRI showed emergence of lesions in 4 cases with normal initial examination and 3 of them presented exacerbations. At the follow-up term, the diagnosis of MS was performed in 15 cases (75 p. 100) CDMs in 66 p. 100, LSDMS in 26 p. 100 and CPMS in one case). This confirms the predictive value of brain MRI and CSF OB for the diagnosis of MS in patients who present with clinically isolated acute syndrome of the spinal cord.

Abstract
Reflex seizures induced by higher mental activity is rare. We report the case of a young man with myoclonic jerks and generalized tonico-clonic convulsion precipitated by calculation, playing chess and scrabble. Routine EEG, including hyperventilation and photic stimulation, showed no abnormality. Tests stimulation procedures, including spatial tasks, induced focal and generalized EEG spike-wave complex and myoclonic jerks. Valproate was effective in reducing epileptic seizures during a follow-up period of three years. Comparison of our case with previously reported reflex epilepsy with seizures induced by higher mental activity is discussed.

Abstract
Recent advances in lateral medullary syndrome have focused on otoneuro-ophthalmology and magnetic resonance imaging (MRI). To reevaluate lateral medullary infarcts, 40 non fatal cases (30 men and 10 women, mean age 57.5 years) accounting for 4.5 p. 100 of overall cerebral infarcts were consecutively included in a prospective study using MRI in all cases. Thirty three patients were investigated using transfemoral or magnetic resonance angiography. Besides classical symptomatology, visual disorders were usually noted: diplopia (n = 18), transient visual tilt of the surrounding (n = 4), skew deviation (= 4), esotropia (n = 2) or conjugate gaze deviation (n = 2). The middle part of the medulla was affected in 35 cases. When associated, ipsilateral peripheral facial palsy and/or deafness were linked to the involvement of the pontomedullary junction (n = 3) while ipsilateral hemiparesis (Opalski's syndrome, n = 4) was linked to the involvement of the lower medulla and the cervicomedullary junction. MRI showed an associated cerebellar infarct in 35 p. 100 of cases. Of 33 patients angiographically investigated, 27 (82 p. 100) had stenosis or occlusion of the ipsilateral vertebral artery, usually affecting the intracranial portion, when 3 had isolated posterior inferior cerebellar artery occlusion. Atherosclerosis was recognized as the main cause of lateral medullary infarcts (n = 25). Other miscellaneous etiologies were diagnosed: coagulopathy (n = 2), spontaneous arterial dissection (n = 2), dolichoectatic artery (n = 1), arteriolopathy (n = 1) or cardiogenic embolism (n = 1). At the term of follow-up (mean: 35 +/- 24 months), 33 patients were free of residual handicap, 8 had experienced recurrent vertebrobasilar infarcts, including 3 medullary infarcts (median ipsilateral, n = 1 or lateral contralateral, n = 2), and 3 were died of basilar artery thrombosis complicating extensive atherosclerosis of the intracranial vertebrobasilar system.

Abstract
BACKGROUND The etiology of Behçet's disease (BD) is uncertain but there is strong evidence that the immune system is implicated in its pathogenesis. METHODS We assessed circulating immune complexes (CIC) in peripheral blood of 34 patients with BD, forming eight clinical groups, using a laser nephelometer to obtain more insight in the pathogenesis of different clinical forms of BD. Twenty healthy controls and eight patients with recurrent oral ulcerations were also included in the study. RESULTS Levels of CIC were significantly higher in patients (1.83 +/- 0.93 microgram/mL) than in controls (0.84 +/- 0.51 microgram/mL; P < 0.001). High titers were found in the groups of patients with erythema nodosum (3.14 +/- 0.44 microgram/mL), neurologic manifestations (2.9 +/- 0.58 microgram/mL), and ocular manifestations (2.34 +/- 0.93 microgram/mL). Compared to patients with recurrent oral ulcerations (1.91 +/- 0.77 microgram/mL), the mean value of CIC in patients with BD did not differ significantly, but the groups of patients having erythema nodosum, positive pathergy, and neurologic manifestations had significantly higher levels (P < 0.05) and the group of patients at the mild end of the spectrum (group 8) had a significantly lower level (1.09 +/- 0.41 microgram/mL) (P < 0.05). Only the groups having erythema nodosum, positive pathergy, and neurologic manifestations had significantly higher levels of CIC when compared to other groups lacking these clinical features, whereas group 8 had a significantly lower level (P < 0.05) when compared to all other groups. CONCLUSION Our results show that CIC may be involved in the pathogenesis of BD, especially in those clinical forms of the disease with erythema nodosum, neurologic manifestations, and ocular manifestations. Patients at the mild end of the BD spectrum do not show significant changes in CIC levels compared to healthy control subjects. We can, therefore, suggest that in BD CIC may be implicated more in the pathogenesis of some features than of others.

Abstract
Five cases are reported of patients with so-called primary progressive apraxia, defined as a slowly worsening disturbance of gestural abilities, without other major cognitive changes during a long period, in relation to degenerative cortical atrophy. All five cases, as other cases in the literature, share the following common features: 1) asymmetrical onset of upper limb clumsiness, more often involving the left side, later involving the contralateral side and lower limbs; 2) after a variable delay, the occurrence of symptoms suggesting subcortical involvement (akinesia, limb stiffness, various kinds of movement disorders, dystonia, paresis of vertical gaze); 3) diffuse cortical atrophy typically more pronounced in the superior parietal cortex opposite to the first side affected. The unusual nature of apraxia in all these cases is pointed out and referred to as Luria's "kinesthaesic apraxia", ascribed to a loss of "selectivity" of distal elementary movements. This pattern of symptoms and their specific outcome could represent a distinct entity.

Abstract
A 49 year-old women with no medical history suddenly presented bilateral striato-capsular infarct causing frontal-like behavioural disturbances associating inertia with loss of drive, interest and affect, and preservation of intellectual function ("athymhormic syndrome" or "loss of psychic self-activation"). Ischaemic lesions mainly affected right globus pallidus and left lentiform nucleus with no involvement of the caput of the nuclei caudati. Such changes were close to anoxic lesions known to cause the same symptomatology. Infarction was attributed to a Moyamoya disease on angiographic data. Bilateral involvement of basal ganglia, arterial borderzones or both, may explain the frequent occurrence of neuropsychological disturbances in Moyamoya disease.
