RESUMO

PURPOSE OF REVIEW: To examine the quantifiable economic impact of inflammatory bowel disease (IBD), key cost drivers and determinants, and the impact of value-based care in IBD. Finally, we prognosticate on future directions and opportunities on healthcare economics in IBD. RECENT FINDINGS: New value-based initiatives, technologically driven interventions, and quality improvement programs have demonstrated reductions in healthcare utilization and enhanced patient outcomes, and several have realized cost of care reductions. IBD is a costly, chronic illness with unbalanced spending by a small proportion of individuals. Pharmaceutical costs are overtaking inpatient expenses as the primary cost driver. Value-based care initiatives including the IBD medical home, remote monitoring platforms such as myIBDcoach and Project Sonar, and learning healthcare networks exemplified by ImproveCareNow have all demonstrated successes in improving care quality, patient outcomes, and reduced healthcare spending in some populations. The future of value-based care in IBD is bright, with ample opportunities for model refinement, collaboration, and growth.

RESUMO

Circadian systems enable organisms to synchronize their physiology to daily and seasonal environmental changes relying on endogenous pacemakers that oscillate with a period close to 24 h even in the absence of external timing cues. The oscillations are achieved by intracellular transcriptional/translational feedback loops thoroughly characterized for many organisms, but still little is known about the presence and characteristics of circadian clocks in fungi other than Neurospora crassa. We sought to characterize the circadian system of a natural isolate of Aureobasidium pullulans, a cold-adapted yeast bearing great biotechnological potential. A. pullulans formed daily concentric rings that were synchronized by light/dark cycles and were also formed in constant darkness with a period of 24.5 h. Moreover, these rhythms were temperature compensated, as evidenced by experiments conducted at temperatures as low as 10 °C. Finally, the expression of clock-essential genes, frequency, white collar-1, white collar-2 and vivid was confirmed. In summary, our results indicate the existence of a functional circadian clock in A. pullulans, capable of sustaining rhythms at very low temperatures and, based on the presence of conserved clock-gene homologues, suggest a molecular and functional relationship to well-described circadian systems.

RESUMO

Colonoscopy is the most widely used screening modality for the detection and removal of colon polyps and for the prevention of colorectal cancer. To identify all colon lesions and reduce the risk of colorectal cancer, it is important to perform a complete colonoscopy. The success of screening colonoscopy depends upon several parameters, including bowel preparation and adenoma detection rate. Incomplete colonoscopy rates vary from 4% to 25% and are associated with higher rates of interval proximal colon cancer. This article reviews the potential causes of and preventive measures for incomplete colonoscopy, as well as techniques and technologies that may improve the rate of complete colonoscopy.

RESUMO

We report the case of a patient presenting with multiple severe electrolyte disturbances who was subsequently found to have small cell lung cancer. Upon further evaluation, she demonstrated three distinct paraneoplastic processes, including the syndrome of inappropriate antidiuretic hormone, Fanconi syndrome, and an inappropriate elevation in fibroblast growth factor-23 (FGF23). The patient underwent one round of chemotherapy, but she was found to have progressive disease. After 36 days of hospitalization, the patient made the decision to enter hospice care and later she expired.

RESUMO

Herbal medicines have been used for the treatment of various ailments since time immemorial. Black cohosh (BC) is well known for the treatment of postmenopausal symptoms, with conflicting evidence supporting its safety and benefits. We present a rare case of BC-induced autoimmune hepatitis (AIH) with hepatotoxicity in a 69-year-old female. To our knowledge, this represents the third case of BC-induced AIH.

RESUMO

Malignancy represents substantial morbidity and mortality in patients with primary sclerosing cholangitis (PSC). This subset of patients has been proven to be at increased risk for developing cholangiocarcinoma, gallbladder carcinoma and colorectal cancer in those with overlapping inflammatory bowel disease. Herein, we review the prevalence of these malignancies and recommend screening tools and current knowledge to reduce the disease burden in this population. Cholangiocarcinoma is the most dominant malignancy affecting PSC patients, with a lifetime risk ranging from 5% to 20%. We advocate for serial US or MRI/MRCP and CA 19-9 to screen for cholangiocarcinoma. Gallbladder cancer has a lifetime risk around 2% in this population and we agree with annual imaging for lesions as recommended by national guidelines. Patients with PSC and concomitant IBD are at increased risk of colorectal carcinoma from time of diagnosis and therefore should likely undergo annual surveillance. The low rates of hepatocellular cancer and pancreatic cancer indicate surveillance for these malignancies is less advantageous.

RESUMO

Lichen planus (LP) is an idiopathic disorder that presents with cutaneous and genital manifestations. Esophageal LP (ELP) was first described by Al-Shihabi and Jackson [J Laryngol Otol 1982;96:567-571] in 1982. Only approximately 80 cases have been documented in the literature since. It is a rare and underrecognized disorder, leading to a delay in diagnosis and a lack of standardized management. We describe the presentation, diagnosis, and management of 6 cases of ELP, at a tertiary institution, because we believe that an increasing awareness of this condition can help identify more cases and increase our understanding of this interesting condition.

Una mujer de 79 años, sin antecedentes patológicos de importancia, consultó al servicio de gastro enterología por síntomas de dispepsia de larga data. Se practicó una esofagogastroduodenoscopia en la que se observó mucosa nodular en la segunda porción del duodeno. Esta morfología y los hallazgos inmunofenotípicos eran indicativos de linfoma folicular de bajo grado. El propósito de este manuscrito es ilustrar al lector sobre esta inusual condición en el duodeno, la cual es patognomónica de linfoma.

RESUMO

Duodenal aspirates are not commonly collected, but they can be easily used in detection of small intestinal bacterial overgrowth (SIBO). Proton pump inhibitor (PPI) use has been proposed to contribute to the development of SIBO. We aimed to determine the yield of SIBO-positive cultures detected in duodenal aspirates, the relationship between SIBO and PPI use, and the clinical outcomes of patients identified by this method. In a retrospective study, we analyzed electronic medical records from 1263 consecutive patients undergoing upper endoscopy at a tertiary medical center. Aspirates were collected thought out the third and fourth portions of the duodenum, and cultures were considered to be positive for SIBO if they produced more than 100,000 cfu/mL. Culture analysis of duodenal aspirates identified SIBO in one-third of patients. A significantly higher percentage of patients with SIBO use PPIs than patients without SIBO, indicating a possible association. Similar proportions of patients with SIBO improved whether or not they received antibiotic treatment, calling into question the use of this expensive therapy for this disorder.

RESUMO

Eosinophilic granulomatosis with polyangiitis (EGPA), formerly named Churg-Strauss syndrome, is a rare systemic small- and medium-sized-vessel vasculitis, characterized by the presence of severe asthma as well as blood and tissue eosinophilia. Gastrointestinal (GI) symptoms, like diarrhea and abdominal pain, are common; however, there are few reports of histologic evidence of GI involvement. We report the case of a patient on treatment for EGPA who presented with recurrent small bowel obstruction and choledocholithiasis. Biopsies of the esophagus, small bowel and common bile duct showed diffuse eosinophilia, with clear EGPA in the GI tract. Improved awareness of GI EGPA may allow for timely management of this disorder.

RESUMO

La cirugía bariátrica es un tratamiento que garantiza una pérdida de peso sustancial y duradera, y beneficios tangibles respecto a condiciones médicas asociadas a la obesidad. El aumento del número de cirugías bariátricas ha llevado también a un aumento de las complicaciones relacionadas con ella, incluyendo la encefalopatía de Wernicke y la polineuropatía por deficiencia de vitaminas del complejo B. En este artículo se reporta un caso de encefalopatía de Wernicke siete semanas después de la cirugía, enfatizando en la importancia de reconocer el espectro de la sintomatología para hacer un diagnóstico temprano, que permita intervenir en la fase reversible de esta enfermedad potencialmente letal.


Bariatric surgery is a treatment that guarantees a substantial and lasting weight loss in addition to the tangible benefits relating to obesity-associated medical conditions. The increasing number of bariatric surgeries has revealed an increasing number of complications related to this procedure, including Wernicke´s encephalopathy and vitamin B deficiency polyneuropathies. Herein, a 7-week post-surgery case of Wernicke´s encephalopathy is presented that emphasizes the importance of an early recognition of these symptoms so as to initiate intervention during the reversible phase of these potentially lethal pathologies.

RESUMO

Se presenta el caso de una paciente de 58 años con esclerosis múltiple diagnosticada en el 2007 tratada con inter-ferón y metilprednisolona; con pobre respuesta en el último año, durante el cual presentó múltiples episodios de exacerbación. Consultó por deterioro neurológico rapidamente progresivo, de una semana de evolución, con un puntaje en la escala de Glasgow de 4/15 (apertura ocular: 2, respuesta verbal: 1, respuesta motora: 1). El caso fue evaluado en junta médica y se consideró como un cuadro atípico de la variante Marburg de esclerosis múltiple. La paciente fue manejada con inmunoglobulina y mitoxantrona, sin mejoría clínica; posteriormente presentó choque distributivo y falleció.


We present a 58 years old woman with multiple sclerosis diagnosed in 2007, she was treated with interferon and methylprednisolone with a stable disease until last year. Recently she had had multiple episodes of exacerbations. Patient was admitted for a rapidly progressive neurological deterioration. When evaluated the patient had a Glasgow scale of 4/15 (Best eye response: 2, Best verbal response: 1, Best motor response: 1). Case was evaluated in a medical board, and was considered an atypical Marburg variant of multiple sclerosis. She was treated with immunoglobulin and mitoxantrone without clinical improvement. Later she developed a distributive shock leading to death.
