Objective: To determine the prevalence of Cysticercus tenuicollis (C. tenuicollis) met-acestodes in five oryx species kept in Al Ain Zoo animal collection.
Methods: This study was based on a retrospective analysis of post-mortem records covering a four year period (July 2010 to July 2014).
Results: A total of 213 individual animals were recorded dead during the four year period (July 2010 to July 2014). Out of this, 12 (5.6%) were recorded with C. tenuicollis. More females (8) than males (4) were recorded to have C. tenuicollis, although this was not statistically significant (P = 0.3737).
Conclusions: This study shows that, Arabian oryx, beisa oryx, fringe-eared oryx, gemsbok and scimitar-horned oryx are susceptible to C. tenuicollis. Based on the epidemiology and the life cycle of this parasite, it is possible that these captive animals ingested the parasite through contaminated feed which could have happened in the pasture land or stray dogs and wild canidae (e.g. fox) visited the zoo contaminating the oryx feed. Stray dogs and wild canidae should be prevented from visiting pasture land and a captive animal facility.
2.Review of Heterotopic Thyroid Autotransplantation.
Clinical and Experimental Otorhinolaryngology 2017;10(4):289-295
Total thyroidectomy is increasingly accepted for the management of bilateral benign thyroid disorders. Postoperatively, patients require lifelong levothyroxine replacement therapy to avoid postoperative hypothyroidism, which besides the burden of compliance, has been proven to be associated with several long-term side effects. Heterotopic thyroid autotransplantation was proposed several decades ago to avoid the need for life-long postoperative replacement therapy with maintaining the autoregulatory mechanism of thyroxin production inside the body according to its needs. Available data regarding this topic in literature is relatively poor. Before applying thyroid autotransplantation on humans, several studies have been done on animals, where the autologous transplantations were found to be successful in almost all the cases, proved by follow up postoperative 8-week measurements of thyroid hormones and histopathological examination of the removed autografts. Regarding the clinical application, few trials have been done using cryopreserved in vivo, in vitro or immediately autotransplanted thyroid autografts. Satisfactory results were obtained, however, the number of these studies and the number of patients per each study was very low. Besides the study methodologies were not so consistent.

Humeral medial epicondyle fractures constitute around 15% of pediatric elbow fractures. Up to 60% occur in association with elbow dislocations. Knowledge of potential imaging pitfalls when examining acute elbow fractures in children contributes significantly to accurate diagnosis. Nevertheless, management of missed pediatric medial epicondyle fractures has rarely been reported. We present an 11-year-old boy with a neglected and severely displaced medial epicondyle fracture with concurrent ulnar nerve palsy. We performed neural decompression, fragment excision, and muscular and capsuloligamentous reconstruction of the medial elbow. This study demonstrates that the surgical outcome of a late presenting fracture can be satisfactory in terms of function and neural recovery. It also underscores the importance of careful interpretation of elbow imaging including normal anatomic variants.

BACKGROUND AND OBJECTIVES: Alzheimer's disease (AD) is a devastating neurodegenerative disorder. Increasing evidence implicates diabetes mellitus (DM) as a risk factor for AD. Green tea (GT) has several beneficial effects attributed to its anti-oxidant phenolic compounds. Adipose tissue is a rich source of adipose-derived mesenchymal stem cells (ADSCs). This study was designed to evaluate and compare the possible therapeutic effect of green tea extract (GTE) and ADSCs on AD complicating induced DM in male rat. METHODS: 31 adult male albino rats were divided into 5 groups. Group I (Control), Group II received GTE, 50 mg/kg daily orally for 4 weeks, Group III received a single intraperitoneal injection of Streptozotocin (STZ), 50 mg/kg, Group IV: received STZ followed by GTE and Group V: received STZ followed by human ADSCs (hADSCs) intravenously. RESULTS: Multiple acidophilic masses, deformed neurons, Congo red +ve masses and Caspase 3 +ve neurons were seen in group III, became few in group IV and occasional in group V. Multiple Prussian blue +ve cells were detected in group V. Some CD44 +ve cells were noticed in group III, became multiple in groups IV and V. The mean area of neurons exhibiting acidophilic cytoplasm, mean area of amyloid plaques and mean area % of Caspase 3 +ve cells indicated a significant increase in group III. The mean area % of CD44 +ve cells recorded a significant increase in group IV. CONCLUSIONS: hADSCs exerted a more marked therapeutic effect on the neurodegenerative changes complicating DM and corresponding to AD.

Purpose:
Locally advanced rectal cancer (LARC) is managed by chemoradiotherapy (CRT), followed by surgery. Herein we reported patients with metastases during or after CRT.
Methods:
Data of patients with LARC who received CRT from 2008 to 2017 were reviewed. Patients with metastases after CRT were included. Those with metastatic tumors at the initial diagnosis were excluded.
Results:
Fourteen patients (1.3%) of 1,092 who received CRT presented with metastases. Magnetic resonance circumferential resection margin (mrCRM) and mesorectal lymph nodes (LNs) were positive in 12 patients (85.7%). Meanwhile, magnetic resonance extramural vascular invasion (mrEMVI) was positive in 10 patients (71.4%). Magnetic resonance tumor regression grade (mrTRG) 4 and mrTRG5 was detected in 5 and 1 patient respectively. Ten patients (71.4%) underwent combined surgery and 3 (21.4%) received palliative chemotherapy.
Conclusion
Patients with metastases after CRT showed a higher rate of positive mrCRM, mrEMVI, mesorectal LNs, and poor tumor response. Further studies with a large number of patients are necessary for better survival outcomes in LARC.
