OBJECTIVEThis study investigated the safety and efficacy of sitagliptin (Januvia) for the inpatient management of type 2 diabetes (T2D) in general medicine and surgery patients.RESEARCH DESIGN AND METHODSIn this pilot, multicenter, open-label, randomized study, patients (n = 90) with a known history of T2D treated with diet, oral antidiabetic agents, or low total daily dose of insulin (≤0.4 units/kg/day) were randomized to receive sitagliptin alone or in combination with glargine insulin (glargine) or to a basal bolus insulin regimen (glargine and lispro) plus supplemental (correction) doses of lispro. Major study outcomes included differences in daily blood glucose (BG), frequency of treatment failures (defined as three or more consecutive BG >240 mg/dL or a mean daily BG >240 mg/dL), and hypoglycemia between groups.RESULTSGlycemic control improved similarly in all treatment groups. There were no differences in the mean daily BG after the 1st day of treatment (P = 0.23), number of readings within a BG target of 70 and 140 mg/dL (P = 0.53), number of BG readings >200 mg/dL (P = 0.23), and number of treatment failures (P > 0.99). The total daily insulin dose and number of insulin injections were significantly less in the sitagliptin groups compared with the basal bolus group (both P < 0.001). There were no differences in length of hospital stay (P = 0.78) or in the number of hypoglycemic events between groups (P = 0.86).CONCLUSIONSResults of this pilot indicate that treatment with sitagliptin alone or in combination with basal insulin is safe and effective for the management of hyperglycemia in general medicine and surgery patients with T2D.
Idiopathic achalasia is a primary esophageal motor disorder characterized by esophageal aperistalsis and abnormal lower esophageal sphincter (LES) relaxation in response to deglutition. It is a rare disease with an annual incidence of approximately 1/100,000 and a prevalence rate of 1/10,000. The disease can occur at any age, with a similar rate in men and women, but is usually diagnosed between 25 and 60 years. It is characterized predominantly by dysphagia to solids and liquids, bland regurgitation, and chest pain. Weight loss (usually between 5 to 10 kg) is present in most but not in all patients. Heartburn occurs in 27%-42% of achalasia patients. Etiology is unknown. Some familial cases have been reported, but the rarity of familial occurrence does not support the hypothesis that genetic inheritance is a significant etiologic factor. Association of achalasia with viral infections and auto-antibodies against myenteric plexus has been reported, but the causal relationship remains unclear. The diagnosis is based on history of the disease, radiography (barium esophagogram), and esophageal motility testing (esophageal manometry). Endoscopic examination is important to rule out malignancy as the cause of achalasia. Treatment is strictly palliative. Current medical and surgical therapeutic options (pneumatic dilation, surgical myotomy, and pharmacologic agents) aimed at reducing the LES pressure and facilitating esophageal emptying by gravity and hydrostatic pressure of retained food and liquids. Although it cannot be permanently cured, excellent palliation is available in over 90% of patients.
Hyperglycemia is a common and costly health care problem in hospitalized patients. In hospital hyperglycemia is defined as any glucose value >7.8 mmol/l (140 mg/dl). Hyperglycemia is present in 40% of critically ill patients and in up to 80% of patients after cardiac surgery, with ~ 80% of ICU patients with hyperglycemia having no history of diabetes prior to admission. The risk of hospital complications relates to the severity of hyperglycemia, with a higher risk observed in patients without a history of diabetes compared to those with known diabetes. Improvement in glycemic control reduces hospital complications and mortality; however, the ideal glycemic target has not been determined. A target glucose level between 7.8 and 10.0 mmol/l (140 and 180 mg/dl) is recommended for the majority of ICU patients. This review aims to present updated recommendations for the inpatient management of hyperglycemia in critically ill patients with and without a history of diabetes.
Oropharyngeal acid reflux is an infrequent occurrence in healthy volunteers without LPR. The normative data for Restech pH catheter may now be compared to those with suspected LPR.
Gastroesophageal reflux disease (GERD) is a common medical condition affecting approximately 35–40% of the adult population in the western world. The role of GERD in causing extra‐esophageal symptoms including laryngitis, asthma, cough, chest pain, and dental erosions is increasingly recognized with renewed interest among gastroenterologists and other specialists. Direct injury by mucosal contact, and vagally mediated reflex from distal esophageal acid exposure are the two possible mechanisms by which reflux‐related extra‐esophageal tissue injuries may occur. Several investigational techniques may be used to diagnose gastroesophageal reflux; however, because of the poor sensitivity of endoscopy and pH monitoring, and the poor specificity of laryngoscopy, empiric therapy with proton‐pump inhibitors (PPI) is now considered the initial diagnostic step in patients suspected of having GERD‐related symptoms. In those who improve with such therapy, it is likely that GERD may be the cause of the extra‐esophageal presentation. In those who are unresponsive to such therapy, other diagnostic testing such as impedance/pH monitoring may be reasonable in order to exclude continued acid or weakly acid reflux. However, PPI‐unresponsive patients usually have causes other than GERD for the extra‐esophageal symptoms and signs.
