RESUMO

A 54-year-old female patient with hypothyroidism and diabetes mellitus type 2 was brought to emergency room by the family members for acute change in mental status. The laboratory evaluation demonstrated findings consistent with acute renal failure (normal renal function 3 months prior to presentation). She was initiated on hemodialysis due to lack of improvement in renal function. Urine culture done prior to initiation of antibiotics was positive for Escherichia coli, which was later confirmed by renal biopsy. Extensive workup for the cause of renal failure including for connective tissue disease, plasmacytoma, obstruction was negative. She was treated with 6 week course of antibiotics with eventual recovery of her renal function in 4 months.

RESUMO

A 37-year-old woman from Puerto Rico presented to our clinic with symptoms of an abdominal distension progressively worsening over 1 year. A CT of an abdomen and pelvis with contrast was performed and revealed bilateral large heterogeneous pelvic adnexal masses with large ascites and right pleural effusion. Tumour markers CA 125 was 766 U/mL and lactate dehydrogenase was 654 U/L. She underwent total abdominal hysterectomy, bilateral salpingo-oophorectomy with pelvic lymph node dissection and partial omentectomy. Pathology of ovarian masses revealed a diffuse large B-cell lymphoma. The staging work-up was negative, which pointed towards the diagnosis of primary ovarian lymphoma. The patient completed 8 cycles of cyclophosphamide, doxorubicin, vincristine, prednisolone chemotherapy. After 18 months of chemotherapy completion, she remains in remission.

RESUMO

BACKGROUND: Ascites remains the most common cause of hospitalization among patients with decompensated cirrhosis. Paracentesis is a relatively safe procedure with low complication rates. Computerized tomography (CT)-guided therapeutic paracentesis could be a safe and effective alternative to unaided or aided (ultrasonogram-guided) bedside paracentesis. In this retrospective study, we aimed to compare the efficacy, safety, and cost-effectiveness of CT-guided paracentesis with bedside paracentesis. METHODS: The period of study was from 2002 to 2012. All patients with cirrhosis who underwent therapeutic paracentesis were included in the study. These patients were divided into two groups. Group I consisted of patients who underwent CT-guided pigtail catheter insertion with ascitic fluid drainage. Group II consisted of patients who underwent beside therapeutic paracentesis after localization of fluid either by physical examination or sonographic localization. We measured the efficacy of CT-guided paracentesis and bedside paracentesis in terms of volume of fluid removed, length of stay, discharge doses of diuretics (spironolactone and furosemide) and number of days to readmission for symptomatic ascites. We also computed the cost-effectiveness of CT-guided therapeutic paracentesis when compared to a bedside procedure. Fischer exact test was used to analyze the distribution of categorical data and unpaired t-test was used for comparison of means. RESULTS: There were a total of 546 unique patients with diagnosed cirrhosis who were admitted to the hospital with symptomatic ascites and underwent therapeutic paracentesis. Two hundred and forty-seven patients underwent CT-guided paracentesis, while 272 patients underwent bedside paracentesis. There was significant inverse correlation between the amount of ascitic fluid removed and total length of stay in the hospital. We found that the volume of fluid removed via a CT-guided pigtail insertion and drainage (2.72 ± 2.02 L) is significantly higher when compared to fluid removed via bedside paracentesis (1.94 ± 1.69). We also found that the interval time period between two successive therapeutic paracenteses was significantly longer for CT group (106.56 ± 75.2 days) when compared to the bedside group (25.57 ± 7.68 days). CONCLUSION: CT-guided paracentesis with pigtail catheter insertion and drainage is a clinically effective, cheap and safe alternative to conventional bedside paracentesis.

RESUMO

Involvement of gastrointestinal tract by cytomegalovirus (CMV) is common. CMV infections mainly run their course without any clinical signs in immunocompetent hosts. In contrast, CMV can cause severe infections with serious consequences in a immunocompromised state typically associated with organ transplants, highly immunosuppressive cancer chemotherapy, advanced HIV infection or treatment with corticosteroids. The incidence and severity of these manifestations of CMV is directly proportional with the degree of cellular immune dysfunction, i.e., CD8+ Cytotoxic T-cell response. Clinical manifestations of CMV can become apparent in different situations including reactivation of CMV from latency, primary infection in a seronegative host, or exposure of a seropositive host to a new strain of CMV. As the clinical signs of CMV in immunodeficient patients are usually sparse, physicians should be highly vigilant about CMV infection, a treatable condition that otherwise is associated with significant mortality. Here we report a rare case of severe gastrointestinal CMV infection with sustained immunodeficiency secondary to treatment with steroids manifesting as fatal duodenal diverticular bleeding.

RESUMO

Blue nevus, a pigmented skin lesion, affects the dermal melanocytes that are rich in melanin. Its occurrence on skin has been well described in literature. Less commonly, involvement of mucosal surfaces especially genitourinary tract has also been noticed. Here we present a rare case of a blue nevus involving the rectum. So far there has been only one prior description of the blue nevus involving the gastrointestinal mucosa. Differentiation of this lesion from melanoma is the key. Simple excision of the blue nevus with a biopsy forceps during the colonoscopy is an effective management.

RESUMO

BACKGROUND: Psoas abscesses are a known cause of back pain, but they have not been reported as a cause of acute lower extremity thromboses and bilateral pulmonary emboli. We report a patient with bilateral psoas abscesses causing extensive pulmonary emboli through compression of the iliac vein. CASE REPORT: A 47-year-old man presented with bilateral leg swelling over 4 weeks. Physical examination revealed a thin male with bilateral leg swelling, extending to the thigh on his left side. He had hemoglobin of 10.5 g/dl, leukocytosis of 16 000/ml, and an elevated D-dimer. A computed tomography (CT) angiogram of his chest showed extensive bilateral pulmonary emboli and infarcts. He remained febrile with vague flank pain, prompting a CT of his abdomen and pelvis that showed large, multiloculated, septated, bilateral psoas abscesses with compression of the left femoral vein by the left psoas abscess and a thrombus distal to the occlusion. Two liters of pus was drained from the left psoas abscess by CT-guidance, and although the Gram staining showed Gram-positive cocci in clusters, cultures from the abscess and blood were negative. A repeat CT showed resolution of the abscesses, and the drain was removed. He was discharged to a nursing home to complete a course of intravenous antibiotics and anticoagulation. CONCLUSIONS: Although the infectious complications of psoas abscesses have been described in the literature, the mechanical complications of bilateral psoas abscesses are lacking. It is important to assess for complete resolution of psoas abscesses through follow-up imaging to prevent venous thromboembolic events.

RESUMO

We report this case of a 63-year-old woman who presented with progressive illness characterized by abdominal pain, weight loss, anorexia, generalized weakness, and fatigue. The patient was found to have obstructive jaundice with multiple mass lesions in the liver, spleen, and kidney on computed tomography scan of abdomen. She developed cholangitis, necessitating an emergent endoscopic retrograde cholangiopancreatography with biliary stenting and decompression. Later, she was found to have hepatic sarcoidosis on wedge biopsy of the liver. Extrinsic compression of biliary tree from mass effect of sarcoid granulomas with superimposed biliary sepsis is rare.

RESUMO

INTRODUCTION: Portal hypertension results from increased resistance to portal blood flow and has the potential complications of variceal bleeding and ascites. The splenoportal veins increase in caliber with worsening portal hypertension, and partially decompress by opening a shunt with systemic circulation, ie, a varix. In the event of portosystemic shunting, there is a differential decompression across the portal vein and splenic vein (portal vein > splenic vein), with a resultant decrease in the ratio of portal vein diameter to that of splenic vein. Portal vein to splenic vein diameter ratio and gradient could be valuable tools in predicting the presence of portosystemic shunting. METHODS: We retrospectively reviewed patients with cirrhosis who underwent esophagogastroduodenoscopy (EGD) for variceal screening and had a computerized tomogram (CT) of the abdomen within 6 months of the index endoscopic study, between January 2009 and December 2013. Patients on nonselective beta blockers, patients with presinusoidal portal hypertension (portal vein thrombosis or extrinsic compression), and patients who had undergone portosystemic shunting procedures (transjugular intrahepatic portosystemic shunt [TIPS]) or balloon-occluded retrograde transvenous obliteration (BRTO) were excluded from the study. Splenic and portal vein diameters were measured (in mm) just proximal and distal to the splenomesenteric venous confluence, respectively. RESULTS: A total of 164 patients were included in the study; of these, 60% (n=98) were male and 40% (n=66) were female. The mean age of the study population was 58.7 years. A total of 126 patients (77%) had varices, while 38 patients (33%) did not. The mean Model for End-Stage Liver Disease (MELD) score was 5.9 for those who had varices as compared with 7.03 for those who did not. The mean of ratios of portal vein to splenic vein diameters in patients with varices was 1.27 (±0.2), while it was 1.5 (±0.23) in those without varices. This difference was statistically significant (P<0.001). The mean of the gradients between the portal vein and splenic vein diameters was 2.7 (±2) mm for patients with varices as compared with 5 (±1.8) mm in those without varices. This difference was also statistically different (P<0.001). These correlations were statistically significant even after controlling for age, sex, and MELD. These radiological indices also had statistically significant correlations with the presence of gastric varices (P=0.018 for the ratio and P=0.01 for the gradient). A discriminant function analysis was performed that generated the equation: D = 2.68 (ratio of portal vein to splenic vein diameters) + 0.187 (gradient of portal vein to splenic vein diameters, in mm) - 4.152. This equation had a very high sensitivity, of 95%, but low specificity, of 26.3%, in predicting the presence of esophageal varices. CONCLUSION: Both venous diameter ratio (portal vein size/splenic vein size) and venous diameter gradient in mm (portal vein size - splenic vein size) calculated from CTs of the abdomen were good predictors of presence of esophageal varices. These parameters might be useful in stratifying patients at risk of developing esophageal varices who are poor candidates for endoscopic evaluation.

RESUMO

BACKGROUND: Large disparities exist in the utilization rates of screening modalities for colorectal cancer (CRC) in different socioeconomic areas. In this study, we evaluated whether the quality of bowel preparation differed significantly among populations with a high risk of CRC compared with that among the general population after matching for potential confounding factors. METHODS: Hispanic and African American patients who underwent routine screening or surveillance colonoscopies in an outpatient setting between 2003 and 2013 were included in this retrospective study. Patients who underwent colonoscopies for emergent indications and repeat routine screening colonoscopies because of prior history of inadequate bowel preparation were excluded from this study. The patients were divided into three groups: patients having an average risk of being diagnosed with CRC (group 1); patients having a high risk of being diagnosed with CRC because of a personal history of adenomatous polyps (group 2); and patients having a high risk of being diagnosed with CRC because of a family history of CRC in first-degree relatives (group 3). All the patients were given preprocedural counseling and written instructions for bowel preparation. Data on demographic information, method of bowel preparation, quality of bowel preparation, comorbidities, and prescription medications were collected. RESULTS: In all, 834 patients had a "high-risk for CRC" surveillance colonoscopy in view of their personal history of adenomatous polyps and were included in group 2. In total, 250 patients had a "high-risk for CRC" screening colonoscopy in view of their family history of CRC in first-degree relatives and were included in group 3. Further, 1,000 patients were selected to serve as controls (after matching for age, sex and ethnicity) and were included in group 1. Bowel preparation was graded as good, fair, or poor by the endoscopist performing the study. We observed a significantly higher number of good bowel preparations in group 2 and group 3 (P=0.0001) when compared with group 1 (controls) after adjusting for comorbidities and usage of prescription medication that could potentially cause colonic dysmotility. These differences were significant in both Hispanic and African American patients. CONCLUSION: Our study showed that perception of CRC risk significantly influenced the bowel preparation behaviors of patients belonging to minority populations, with a significantly greater number of patients with a high risk of CRC having adequate bowel preparations.

RESUMO

INTRODUCTION: Serotonin reuptake inhibitors (SRIs) are one of the most commonly prescribed classes of medications with a relatively safe side-effect profile. However, SRIs are being increasingly reported to be associated with bleeding complications in patients undergoing invasive procedures resulting from inhibition of serotonin reuptake by platelets and impaired platelet aggregation. The aim of our study was to determine whether there is an increased risk of post-percutaneous endoscopic gastrostomy (PEG) bleeding in patients exposed to SRIs after controlling for other mediations known to increase the risk of bleeding and major comorbidities. METHODS: This was a single-center cohort study that included who underwent PEG tube placement by standard pull-guidewire technique from July 2006 to June 2014. Patients were categorized into groups based on the medications (SRIs, aspirin, non-steroidal anti-inflammatory drugs, and anticoagulants) administered during the index hospitalization. The incidence of post-PEG bleeding was noted in two distinct post-procedure periods: within 48 hours, and between 48 hours and 14 days. RESULTS: A total of 637 PEG tube placements were done on 570 patients during the study period. There were 107 patients (18.8%) with major bleeding within 48 hours of PEG and 79 patients (13.9%) with major bleeding between 48 hours and 14 days. There was no significant increase in the post-PEG bleeding in patients taking a combination of an SRI along with aspirin or non-steroidal anti-inflammatory drugs. Patients on subcutaneous heparin for prophylaxis against thromboembolic events were more likely to have oozing at the PEG site requiring blood transfusion. CONCLUSION: We did not notice an increase in post-PEG bleeding in patients on SRIs. However, in view of the limitation that our study is retrospective and that there are no known significant side effects of withdrawal of SRIs for a short duration, withholding SRIs could be a safe clinical option in patients undergoing PEG tube placement.

RESUMO

BACKGROUND: The aim of this study was to investigate whether systemic vascular resistance (SVR) correlates with validated prospective scoring systems such as Model for End-stage Liver Disease (MELD) and its modifications. METHODS: Patients with cirrhosis, who were admitted to hospital with decompensation (as defined by development of ascites, hepatic encephalopathy, and variceal bleeding) and underwent echocardiography were included in this study. Laboratory data required for computing MELD score, serum bilirubin, serum creatinine, international normalized ratio, and serum sodium were collected for every patient. We tabulated hemodynamic and echocardiography parameters that enabled calculation of SVR. We analyzed the correlation between SVR and each of the individual prognostic scores. RESULTS: A total of 771 patients with a diagnosis of decompensated cirrhosis were included in the study. Two hundred and sixty-two patients were found to have a low sodium level (<135 mEq/L) and 509 were found to have a normal sodium level (>135 mEq/L). In the patients with hyponatremia, we found statistically significant inverse correlations between SVR and validated liver severity models. However, these correlations were not seen in patients with normonatremia. CONCLUSION: We observed a statistically significant inverse correlation between SVR and all the validated liver disease severity models used in this study among patients with hyponatremia but not in those with normonatremia.
