The Jos Plateau has been reported to have elevated levels of natural background radiation. A few earlier studies have measured the levels of natural radioactivity for specific locations in the area. Our interest is to investigate how geology of the study area influences the activity concentrations of natural radionuclides. Thus, the activity concentrations of terrestrial radionuclides in soil samples collected across the geological formations of the Jos Plateau were determined by gamma spectrometry technique...

BACKGROUND: The causes of chronic diskogenic back pain have not yet been clearly identified. Neural ingrowth around the annulus is widely considered to be one of the possible cause. However, neuropathy around the annulus has yet to be observed visually. We report a case of a hotspot that was observed in an epiduroscopic view, but not in imaging findings. CASE DESCRIPTION: A 46-year-old woman was admitted with pain in the back, left buttock, and posterior thigh for 2 years...

BACKGROUND: Lumbar radicular pain often results from lumbar disc herniation, spinal stenosis, or degenerative spondylolisthesis. Minimally invasive disc decompression procedures, such as nucleo-annuloplasty or epiduroscopic neural decompression by laser, have been devised to treat such pain. OBJECTIVE: The short-term outcomes of disc decompression by endoscopic epidural laser decompression (EELD) or transforaminal epiduroscopic laser annuloplasty (TELA) were compared in patients with lumbar radicular pain due to disc herniation...

We describe the preliminary national experience and the early results of the use of robotic surgery to perform the posterior separation of abdominal wall components by the Transversus Abdominis Release (TAR) technique for the correction of complex defects of the abdominal wall. We performed the procedures between 04/2/2015 and 06/15/2015 and the follow-up time was up to six months, with a minimum of two months. The mean surgical time was five hours and 40 minutes. Two patients required laparoscopic re-intervention, since one developed hernia by peritoneal migration of the mesh and one had mesh extrusion...

Invasive lionfish (Pterois volitans and P. miles) have spread widely across the western Atlantic and are recognized as a major threat to native marine biodiversity. Although lionfish inhabit both shallow reefs and mesophotic coral ecosystems (MCEs; reefs from 30 to 150 m depth), the primary management response implemented by many countries has been diver-led culling limited to reefs less than 30 m. However, many reef fish undergo ontogenetic migrations, with the largest and therefore most fecund individuals found at greatest depths...

Background: Lumbar hernias are rare. Usually manifest with reducible volume increase in the post-lateral region of the abdomen and may occur in two specific anatomic defects: the triangles of Grynfelt (upper) and Petit (lower). Despite controversies with better repair, laparoscopic approach, following the same principle of the treatment of inguinal hernias, seems to present significant advantages compared to conventional/open surgeries. However, some technical and anatomical details of the region, non usual to general surgeons, are fundamental for proper repair...

BACKGROUND: The endoscopic technique has been recognised as a viable and safe alternative to microsurgery for the treatment of third-ventricle colloid cyst. However, the standard precoronal endoscopic approach does not always provide an adequate visualisation of the attachment of the cyst to the velum interpositum. Using a more anterior approach, it is easier to reach the roof of the cyst and its possible adherences with the tela choroidea. METHOD: The authors describe step by step the anterior trans-frontal endoscopic approach for management of third ventricle colloid cyst...

Extraskeletal osteosarcoma is a very rare tumor in humans and animals. This paper describes a case of extraskeletal osteosarcoma observed in the duodenum of a male ICR mouse. Grossly, a solid mass pushing up the tunica serosa was observed in the duodenal wall. Histologically, the tumor was located in the lamina propria mucosae and tela mucosa. Neoplastic cells densely proliferated in these areas, and replaced of the normal tissue components. A small amount of osteoid and a small clump of bone tissue were observed in the area of neoplastic cell proliferation, especially in the lamina propria mucosae...

AIMS: The low efficacy rates reported for conventional catheter ablation of longstanding persistent atrial fibrillation (LPAF) have led to the development of alternative techniques such as minimal invasive surgical ablation, aiming for durable and contiguous transmural lesions. The aim was to evaluate the efficacy and safety of total thoracoscopic epicardial left atrial ablation (TELA-AF) procedures in a prospective study of severely symptomatic patients with either drug-resistant AF and/or failed attempts of catheter ablation...

UNLABELLED: Almost all conventional cytostatics are dosed according to body surface area of the patient. Many monoclonal antibodies are also dosed with respect to body surface area or body weight of the patient. While in some European countries, there is recent information describing the anthropometrics of the cancer population, no data are available for Czech population. That is the reason why body surface area and weight of adult patients who were administered chemotherapy at Masaryk Memorial Cancer Institute in 2013 and 2014 were evaluated...

Six hundred fourteen strains of Salmonella enterica were isolated from 16,926 samples of food of animal origin collected in southern Italy from 2003 to 2012. The isolates were identified, serotyped, and challenged against 15 antibiotics according to the protocol defined at national level for veterinary isolates of Salmonella (EnterVet surveillance network). Salmonella serotypes Typhimurium, Hadar, Enteritidis, Derby, and 4,[5],12:i:- were those most frequently isolated. The widest resistances were recorded towards sulfonamides (69 % of the isolates), trimethoprim-sulfamethoxazole (52 % of the isolates), and tetracycline (51 % of the isolates)...

The authors report an illustrative case of a purely endoscopic surgical approach to successfully remove a solid choroid plexus papilloma of the third ventricle in an infant. A 10-week-old male infant first presented with transient episodes of forced downward gaze, divergent macrocephaly, a tense anterior fontanel, diastasis of the cranial sutures, and papilledema. Brain MRI revealed a small, multilobulated contrast-enhancing mass situated within the posterior third ventricle, with resultant obstructive hydrocephalus...

BACKGROUND: Posterior fossa brain tumors are common in children. Symptoms typically develop when the tumors have reached sufficient size to cause compression of adjacent neural structures or cause obstructive hydrocephalus. Many tumors in this region originate from the tela choroidea and choroid plexus of the fourth ventricle. Enhancement of the fourth ventricular tela choroidea and choroid plexus is uncommon in children, and when such enhancement is present, it may represent early tumor growth...

BACKGROUND: When there is an insurgency, the use of force in the form of weaponry, is employed. This may lead to the total breakdown of law and order, resulting in destruction of life and property. Health workers may be killed or captured, and, health facilities destroyed or stretched beyond their functional capacity. This is a report of experience with injuries seen in a tertiary hospital in north eastern Nigeria, under an insurgency situation. MATERIALS AND METHODS: After obtaining clearance from the medical Ethics Committee of UMTH, we reviewed the case files of all patients treated for injuries sustained as a result of the Boko Haram insurgency from January 2009 to December 2013...

BACKGROUND: The "telo-velar" approach is an alternative to cerebellar splitting to gain access to the fourth ventricle through the so-called cerebello-medullary fissure (CMF). METHOD: In this approach, the CMF is exposed and access to the ventricle is obtained by incising the tela chorioidea and inferior medullary velum. This approach enables the exploration of the entire ventricle cavity from the obex to the aqueduct. CONCLUSIONS: The exposure of the fourth ventricle is satisfactory and the floor of the fourth ventricle can be visualised early and protected...
