New insights on accretion in supergiant fast X-ray transients from XMM-Newton and INTEGRAL observations of IGR J17544-2619
XMM–Newton observations of the supergiant fast X-ray transient IGR J17544?2619 are reported and placed in the context of an analysis of archival INTEGRAL/IBIS data that provide a refined estimate of the orbital period at 4.9272?±?0.0004?d. A complete outburst history across the INTEGRAL mission is reported. Although the new XMM–Newton observations (each lasting ?15 ks) targeted the peak flux in the phase-folded hard X-ray light curve of IGR J17544?2619, no bright outbursts were observed, the source spending the majority of the exposure at intermediate luminosities of the order of several 1033?erg?s?1 (0.5–10 keV) and displaying only low level flickering activity. For the final portion of the exposure, the luminosity of IGR J17544?2619 dropped to ?4?×?1032?erg?s?1 (0.5–10 keV), comparable with the lowest luminosities ever detected from this source, despite the observations being taken near to periastron. We consider the possible orbital geometry of IGR J17544?2619 and the implications for the nature of the mass transfer and accretion mechanisms for both IGR J17544?2619 and the supergiant fast X-ray transients (SFXTs) population. We conclude that accretion under the ‘quasi-spherical accretion’ model provides a good description of the behaviour of IGR J17544?2619 and suggests an additional mechanism for generating outbursts based upon the mass accumulation rate in the hot shell (atmosphere) that forms around the neutron star under the quasi-spherical formulation. Hence, we hope to aid in explaining the varied outburst behaviours observed across the SFXT population with a consistent underlying physical model
A 2 h periodic variation in the low-mass X-ray binary Ser X-1
Spectroscopy of the low-mass X-ray binary Ser X-1 using the Gran Telescopio Canarias have revealed a ?2 h periodic variability that is present in the three strongest emission lines. We tentatively interpret this variability as due to orbital motion, making it the first indication of the orbital period of Ser X-1. Together with the fact that the emission lines are remarkably narrow, but still resolved, we show that a main-sequence K dwarf together with a canonical 1.4 M? neutron star gives a good description of the system. In this scenario, the most likely place for the emission lines to arise is the accretion disc, instead of a localized region in the binary (such as the irradiated surface or the stream-impact point), and their narrowness is due instead to the low inclination (?10°) of Ser X-1
Endoscopic evaluation of upper and lower gastro-intestinal bleeding
Introduction: A myriad of pathologies lead to gastro-intestinal bleeding (GIB). The common clinical presentations are hematemesis, melena, and hematochezia. Endoscopy aids localization and treatment of these lesions. Aims: The aim was to study the differential diagnosis of GIB emphasizing the role of endoscopy in diagnosis and treatment of GIB. Patients and Methods: A prospective study of patients with GIB referred to the Endoscopy unit of two health facilities in Port Harcourt Nigeria from February 2012 to August 2014. The variables studied included: Demographics, clinical presentation, risk score, endoscopic findings, therapeutic procedure, and outcome. Data were collated and analyzed using SPSS version 20 software. Results: A total of 159 upper and lower gastro-intestinal (GI) endoscopies were performed during the study period with 59 cases of GI bleeding. There were 50 males and 9 females with an age range of 13-86 years (mean age 52.4 20.6 years). The primary presentations were hematochezia, hematemesis, and melena in 44 (75%), 9 (15%), and 6 (10%) cases, respectively. Hemorrhoids were the leading cause of lower GIB seen in 15 cases (41%). The majority of pathologies in upper GIB were seen in the stomach (39%): Gastritis and benign gastric ulcer. Injection sclerotherapy was successfully performed in the hemorrhoids and a case of gastric varices. The mortality recorded was 0%. Conclusion: Endoscopy is vital in the diagnosis and treatment of GIB. Gastritis and Haemorrhoid are the most common causes of upper and lower GI bleeding respectively, in our environmen

Pilot study on laparoscopic surgery in Port-Harcourt, Nigeria
Background: Video-laparoscopic surgery has long been practiced in western countries; however documented practice of this minimal access surgical technique are recently emanating from Nigeria. To the best of our knowledge, this is the first documented study on laparoscopic surgery from the Niger Delta region. Aim: To evaluate the feasibility of laparoscopy as a useful tool for management of common surgical abdominal conditions in our environment. Patients and Methods: This was a prospective outcome study of all consecutive surgical patients who had laparoscopic procedures in general and pediatric surgery units of our institution from August 2011 to December 2012. Data on patient′s age, gender, indication for surgery, duration of hospital stay and outcome of surgery were collected and analyzed. Results: A total of 15 laparoscopic procedures were performed during this study period with age range of 2-65 years; mean: 32.27 ± 17.86 years. There were 11 males and four females. Six laparoscopic appendicectomies, one laparoscopy-assisted orchidopexy, five diagnostic laparoscopy ± biopsy, one laparoscopic trans-abdominal pre-peritoneal herniorrhaphy for bilateral indirect inguinal hernia and two laparoscopic adhesiolysis for small bowel obstruction were performed. All were successfully completed except one conversion (6.7%) for uncontrollable bleeding in an intra-abdominal tumor. Conclusion: The practice of laparoscopic surgery in our environment is feasible and safe despite the numerous, but surmountable challenges. There is the need for adequate training of the support staff and a dedicated theatre suite
