RESUMEN

BACKGROUND & AIMS: The American Association for the Study of Liver Diseases recommends the use of a 2-grade classification system (small and large) to describe the size of oesophageal varices (OV). Data on observer agreement (OA) on this system are currently lacking. We aimed to evaluate this classification and compare it to the widely used 3-grade classification (grade 1 'small', grade 2 'medium', grade 3 'large') among operators of variable experience. METHODS: High-definition video recordings of 100 patients with cirrhosis were prospectively collected using standardised criteria. Nine observers of variable experience performed independent evaluations of the videos in random order. OV were scored using both systems. All assessments were repeated a year later by the same observers to assess intra-observer agreement. RESULTS: Interobserver agreement (all observers) using the 2-grade and the 3-grade system was k = 0.71 (95% CI: 0.64-0.78) and k = 0.73 (95% CI: 0.66-0.79) respectively. When using the 2-grade system, intra-observer agreement between hepatologists (n = 3), luminal gastroenterologists (n = 3) and trainee gastroenterologists (n = 3) was k = 0.89 (95% CI: 0.86-0.91), k = 0.72 (95% CI: 0.67-0.77), and k = 0.74 (95% CI: 0.67-0.8) respectively. With the 3-grade system; intra-observer agreement between the same three subgroups were k = 0.9 (95% CI: 0.87-0.92), k = 0.73 (95% CI: 0.68-0.78), k = 0.77 (95% CI: 0.71-0.82) respectively. CONCLUSIONS: There was no difference in OA between the 2-grade and 3-grade classification systems. Hepatologists had significantly higher levels of consistency in grading OV. This may have implications to create alternative training models for residents and fellows in the recognition and grading of OV.

RESUMEN

BACKGROUND: To report the neuro-ophthalmological findings in the TAFRO syndrome in a South American patient. METHODS: This is a case report of a patient with TAFRO syndrome. RESULTS: We present the case of a 66-year-old woman with TAFRO syndrome and multicentric Castleman disease, who developed ophthalmic manifestations, as a rare complication, including optic disk edema and serous retinal detachment, which improved with conventional therapy. CONCLUSIONS: The optic disk edema could be present as a neuro-ophthalmological finding in TAFRO syndrome. To the best of our knowledge, this is the first report on the ophthalmic manifestations in the TAFRO syndrome.

RESUMEN

BACKGROUND: To report the clinical, electrophysiological and the anatomical findings in a patient with Kearns-Sayre syndrome (KSS). CASE PRESENTATION: We present the case of a 55-year-old female with KSS, who developed systemic features and ocular manifestations as ophthalmoplegia and retinal dysfunction, that were corroborated by electrophysiological test and High Definition Spectral Domain Optical Coherence Tomography (HD SD OCT) and OCT-Angiography (OCT-A). CONCLUSION: We report a patient with KSS, accompanied by some alterations of the RPE and photoreceptors observed in the external HD SD OCT and OCT-A. In the best of our knowledge, this is the first report in the literature of HD SD OCT findings in a patient with KSS.

RESUMEN

INTRODUCCIÓN. La poliposis nasal es una enfermedad multifactorial con prevalencia en la población general del 2 al 5 por ciento. Fue objetivo de este estudio comparar los resultados quirúrgicos en 60 pacientes con poliposis nasosinusal, operados con microdesbridador y sin él. MÉTODOS. Se analizaron 60 pacientes operados entre el 2002 y el 2006. Se estudiaron factores relacionados, como asma, intolerancia al ácido acetilsalicílico y alergia. Fueron consideradas las cirugías previas, endoscópicas o convencionales, así como las complicaciones menores y mayores derivadas de éstas. Se revisaron los casos que no se lograron controlar con tratamiento médico. RESULTADOS. Los resultados globales fueron satisfactorios: a los 2 años 29 pacientes (48,3 por ciento) estaban asintomáticos, 45 (75 por ciento) con las fosas libres de pólipos, 11 (18,3 por ciento) con recidiva controlada con tratamiento médico y hubo que reintervenir solo a 2 pacientes (3,3 por ciento). El número de complicaciones permaneció muy por debajo del nivel razonable; hubo solo 2 (3,3 por ciento) complicaciones mayores: un hematoma periorbitario y una lesión de lámina papirácea. CONCLUSIONES. Las afecciones inflamatorias nasosinusales, y en especial la poliposis nasal, se benefician con un tratamiento quirúrgico endoscópico. La experiencia y el uso de instrumental motorizado (microdesbridador) han mejorado aún más los resultados de esta técnica(AU)

The figure of complications remained very low of the reasonable level; there was only 2 (3,3 percent) (major complications): a periorbital hematoma and a lesion of papyraceous plate. CONCLUSIONS. The nasosinusal affections and specially the nasal polyposis to do well out the endoscopic surgical treatment. The experience and the use of motorized instrumental (micro- defibrillator) have improved even more the results of this technique(AU)

RESUMEN

BACKGROUND: There is a lack of prospective studies evaluating the natural history of colonic ischaemia (CI). We performed such a study to evaluate the clinical presentation, outcome, and mortality as well as clinical variables associated with poor prognosis. METHODS: An open, prospective, and multicentre study was conducted in 24 Spanish hospitals serving a population of 3.5 million people. The study included only patients who met criteria for definitive or probable CI. A website (www.colitisisquemica.org) provided logistical support. RESULTS: A total of 364 patients met criteria for inclusion. CI was suspected clinically in only 24.2% of cases. The distribution of clinical patterns was as follows: reversible colopathy (26.1%), transient colitis (43.7%), gangrenous colitis (9.9%), fulminant pancolitis (2.5%), and chronic segmental colitis (17.9%). A total of 47 patients (12.9%) had an unfavorable outcome as defined by mortality and/or the need for surgery. Multivariate analysis identified the following signs as independent risk factors for an unfavorable outcome: abdominal pain without rectal bleeding [odds ratio (OR) 3.9; 95% confidence interval (CI) = 1.6-9.3], non-bloody diarrhoea (OR 10; 95% CI = 3.7-27.4), and peritoneal signs (OR 7.3; 95% CI = 2.7-19.6). Unfavorable outcomes also were more frequent in isolated right colon ischaemia (IRCI) compared with non-IRCI (40.9 vs. 10.3%, respectively; p < 0.0001). The overall mortality rate was 7.7%. CONCLUSIONS: The clinical presentation of CI is very heterogeneous, perhaps explaining why clinical suspicion of this disease is so low. The presence of IRCI, and occurrence of peritoneal signs or onset of CI as severe abdominal pain without bleeding, should alert the physician to a potentially unfavorable course.
