The perfect pelvic pouch--what makes the difference?

The aim of this study was to determine what factors are important for the achievement of perfect anal continence after restorative proctocolectomy. One hundred patients underwent paired studies of anorectal physiology before and one year after restorative proctocolectomy with pelvic ileal reservoir (11 S, 25 J, 64 W) with stapled ileoanal anastomosis, without mucosectomy. Fifty seven patients attained perfect anal continence and were able to discriminate flatus from faeces with such confidence that they were able to release flatus safely without fear of faecal soiling. The remaining 43 patients experienced minor problems in this regard. Four factors were found to correlate significantly with a perfect functional result (median, perfect v imperfect): maximum resting anal pressure (72 v 57 cm H2O, p < 0.02), the sensory threshold in the upper and mid-anal canal (7.3 v 8.6 and 5.3 v 7.0 mA, p < 0.05 and p < 0.02), compliance of the ileal reservoir (12.4 v 7.6 ml/cm H2O, p < 0.01), and the presence of a pouch-anal inhibitory reflex (56 of 57 patients v 29 of 43 patients, p < 0.01). The quality of anal continence depends on several factors: a complaint ileal reservoir, a strong sensitive anal sphincter, and normal reflex coordination of the activities of the reservoir and the sphincter. Excellent pouch-anal coordination is obtainable irrespective of the design of the reservoir, provided that these criteria are satisfied.     

The Assessment of a Rapid Noninvasive Immunochromatographic Assay Test for Fecal Lactoferrin in Patients with Suspected Inflammation of the Ileal Pouch

Purpose

Pouchitis is a common complication after ileal pouch-anal anastomosis. Diagnosis is based on the Pouch Disease Activity Index, which comprises clinical symptoms, endoscopic appearance, and histologic confirmation. A Pouch Disease Activity Index ≥ 7 confirms pouchitis. Fecal lactoferrin is a marker of intestinal inflammation, which can aid in the diagnosis of pouchitis. The IBD EZ VUE? test is a simple, rapid, noninvasive test for fecal lactoferrin. Our goal was to study the sensitivity and specificity of this test in the diagnosis of pouchitis.

Methods

Consecutive patients with pouch dysfunction were recruited from October 2005 to July 2006. A fecal sample was collected before calculation of the Pouch Disease Activity Index. An IBD EZ VUE? test was performed on each fecal sample and the results correlated with the diagnosis of pouchitis to calculate sensitivity and specificity of the IBD EZ VUE? test.

Results

There were 32 patients (21 healthy and 11 inflammed pouches). The IBD EZ VUE? test was positive in 14 patients. It had a sensitivity of 100 percent and a specificity of 86 percent in diagnosing pouchitis. The positive predictive value was 76 percent. There were three false-positive results.

Conclusions

The IBD EZ VUE? test is a sensitive method that may remove the need for invasive pouch investigations and lead to greater confidence when antibiotic therapy is commenced. Further investigations may be reserved for those patients who have a positive lactoferrin test and fail to respond to antibiotic treatment.     

An audit of the treatment of cancer of the oesophagus.

The treatment of cancer of the oesophagus in The General Infirmary at Leeds between the years 1975 and 1988 was reviewed. All cases with histologically proved cancer of the oesophagus were included, data being obtained from case notes, theatre operation books, endoscopy records, pathology records, and the Yorkshire Cancer Registry. Three hundred and sixteen patients were identified. Demographic details, mode of presentation, preoperative investigations, surgical management, methods of palliation, and survival data were entered into a database. The male to female ratio was 3:2 and the median age at presentation was 69 years (range 35-96). Surgical exploration was carried out in 134 of 316 patients (42%). Resection of the tumour, whether curative or palliative, was possible in 106 of 134 patients (79%). Operative (30 day) mortality was 27%. In 22 of 134 patients (16%), only intubation of the tumour was possible, while six patients (5%) had a thoracotomy or laparotomy alone. Median survival of the 106 patients after surgical resection was 292 days (range 0-14.2 years) and seven of them (7%) were still alive five years later. Of the remaining 182 patients (58%) who were not operated upon, 36 patients (11%) had a radical course of radiotherapy with a median survival of 175 days (range 80-453) and 146 patients (46%) either had endoscopic intubation (n = 64) or received no specific treatment (n = 82) with a median survival of 106 days (1-725) and 91 days (1-358) respectively. None of the 182 patients who did not have surgical treatment was alive at five years.

Haemorrhage control beyond Advanced Trauma Life Support (ATLS) protocol in life threatening maxillofacial trauma – experience from a level Ⅰ trauma centre

Maxillofacial injuries are usually not life-threatening and do not get priority over other associated injuries. However, some maxillofacial injuries with active oral or nasal bleeding need immediate management due to threatened airway and blood loss. In the case of major active vascular bleeding, measures such as local pressure, anterior nasal packing, posterior nasal packing, and balloon tamponade are ineffective. In these cases, angiography and transcatheter arterial embolisation (TAE) are used to treat life-threatening haemorrhage caused by maxillofacial trauma. We analysed the medical records of 39 patients with severe maxillofacial trauma and life-threatening haemorrhage that was a result of intractable oral or nasal bleeding. These patients were considered for TAE from January 2010 to December 2019. A total of 1668 patients was admitted, out of which 39 (2.3%) had severe maxillofacial injuries with life-threatening oral or nasal bleeding and underwent TAE. Out of a total of 39 patients, 38 were male and one female. Ages ranged from 16 to 65 years. Road traffic injury was the most common cause of injury (79.5%), Lefort I and II were the most common facial fractures, and traumatic brain injury was the most common associated injury. Embolisation and bleeding control were done successfully in all 39 patients with no procedure-related complications. A total of 17 deaths during the study period were due to severe traumatic brain injuries or haemorrhagic shock.     

Structural,mechanical, dielectric properties and magnetic interactions in Dy3+-substituted Co–Cu–Zn nanoferrites

Sol–gel-synthesized Co–Cu–Zn ferrite nanoparticles diluted with Dy³⁺ ions were investigated in terms of their structural, morphological, elastic, magnetic and dielectric properties. X-ray diffraction patterns showed the formation of a single-phase cubic spinel structure. As the concentration of Dy³⁺ ions was increased, the lattice length gradually increased from 8.340 to 8.545 Å, obeying Vegard''s law. The Williamson–Hall (W–H) method was employed to observe the change in the lattice strain. Crystallite size obtained from W–H plots followed a pattern similar to that observed using the Scherrer equation. The cation distribution suggested a strong preference of Dy³⁺ ions for the octahedral B site while Cu²⁺ and Fe³⁺ ions were distributed over both A and B sites. The microstructures of the samples were visualized using transmission electron microscopy. Mechanical properties such as stiffness constant, longitudinal and transverse wave velocities, Young''s modulus, bulk modulus, rigidity modulus, Poisson''s ratio and Debye temperature were investigated by acquiring infrared spectra recorded in the range of 300 to 800 cm⁻¹. Replacement of Fe³⁺ ions with the strongly magnetic Dy³⁺ ions increased the saturation magnetization and coercivity. Dielectric constant increased with Dy³⁺ substitution but decreased with applied frequency.
