RESUMO

Chronic limb-threatening ischemia (CLTI) is an important issue for elderly patients with peripheral artery disease. Here, we present the case of a 91-year-old man with CLTI, residing in a rural district. The onset of CLTI rapidly deprived him of ambulation because of a foot infection. Given that he had difficulty with long-distance transportation, limb salvage for extensive tissue loss was performed at a district facility, based on his and his family's request. Finally, skin grafting on the cutting plane of the right ankle bones resulted in wound healing in six months after incomplete revascularization and multiple minor amputations.

RESUMO

INTRODUCTION: Proton pump inhibitor (PPI) use is associated with the development of fundic gland polyps (FGPs); discontinuing PPIs is associated with regression of FGPs. Here, we report a rare case of non-respondent FGPs after discontinuation of PPI that were successfully treated using an argon plasma coagulator (APC). PRESENTATION OF CASE: We present the case of a 68-year-old woman with a history of polycytheamia vera. She also had gastroesophageal reflux disease (GERD) and had been taking 10 mg of omeprazole daily for the past three years. Esophagogastroduedenoscopy (GF) revealed over 100 pedunculated polyps in the gastric body and fundus. Histological examination of the specimens showed dilated oxyntic glands with flattened parietal and mucous cells. Based on these findings and the clinical history, a diagnosis of FGPs was made. Omeprazole use was then discontinued. Repeat GF performed 6 months and 1 year later showed a significant increase in the number and size of the polyps. APC treatment was performed every 6 months for 3 years. Further GF showed a significant decrease in the number and size of the FGPs 4 years after discontinuing PPI. DISCUSSION: We conclude that PPI use is a strong risk factor for the development of FGPs and discontinuing PPI is associated with regression of FGPs, but not in patients with polycythaemia vera. However, the mechanism involved in the interaction between FGP and polycytheamia vera remains unknown. CONCLUSION: Non-respondent FGPs after discontinuation of PPI use may be successfully treated using APC.

RESUMO

PURPOSE: Despite the widespread use of percutaneous endoscopic gastrostomy (PEG) tubes, their placement may be associated with a variety of complications, including gastrocolic fistula. MATERIALS AND METHODS: In total, seven high-risk individuals diagnosed using computed tomography (CT)-gastrocolonography (GC) underwent laparoscopic-assisted PEG (LAPEG) placement. Study endpoints included the success of LAPEG under local anesthetic and intravenous sedation, inability to thread the PEG tube, the eventual tube location, the number of tube adjustments needed, adverse events, the operating time, and PEG tube-related infection. RESULTS: In total, 135 PEG procedures were performed during this study. Successful CT-GC was achieved in all 135 patients, and we successfully used a standard PEG technique to place the gastrostomy tube in 128 patients (95%). In seven patients (5%), the LAPEG technique was used because the transverse colon became interposed between the abdominal wall and the anterior wall of the stomach. LAPEG procedure-related minor complications were observed in two patients. CONCLUSIONS: LAPEG combined with CT-GC can be used for patients with difficult anatomical orientations and may minimize the risk of complications in PEG placement.

RESUMO

BACKGROUND AND PURPOSE: We aimed to determine the success rate and any complications using a percutaneous approach to the femoral vein (FV) for placement of a totally implantable access port (TIVAP), with a preoperative assessment of the femoral and iliac veins using computed tomography-venography (CT-V). METHODS: A prospective study of 72 patients was conducted where placement of a TIVAP was attempted via the right FV, with the port placed in the anterior thigh, when subclavian vein or jugular vein access was contraindicated. Preoperative assessment of the femoral venous plexus was performed with CT-V in 72 patients. RESULTS: CT-V success was achieved in 72 of 72 patients (100%). The average distance between the inguinal ligament and the saphenofeomral (FV-GSV) junction was 42.8 ± 12.9 mm. The FV approach had a 97% successful cannulation rate. Two patients had a thrombosis in either the femoral vein or the great saphenous vein. One procedural complication (1.4%) and one initial complication (1.4%) occurred. Late complications occurred in four patients (5.7%). CONCLUSIONS: The percutaneous FV approach with CT-V guidance is an option for patients with multiple central venous cannulations, as well as those with bilateral breast cancer, or those undergoing hemodialysis.

RESUMO

INTRODUCTION: Rhabdomyolysis associated with the use of pregabalin or azithromycin has been demonstrated to be a rare but potentially life-threatening adverse event. Here, we report an extremely rare case of rhabdomyolysis with purpura in a patient who had used pregabalin and azithromycin. PRESENTATION OF CASE: We present the case of a 75-year-old woman with a history of fibromyalgia who was admitted with mild limb weakness and lower abdominal purpura. She was prescribed pregabalin (75mg, twice daily) for almost 3 months to treat chronic back pain. Her medical history revealed that 3days before admission, she began experiencing acute bronchitis and was treated with a single dose of azithromycin (500mg). She had developed rapid onset severe myalgia, mild whole body edema, muscle weakness leading to gait instability, abdominal purpura and tender purpura on the lower extremities. Laboratory values included a white blood cell count of 25,400/mL and a creatinine phosphokinase (CPK) concentration of 1250 IU/L. Based on these findings and the patient's clinical history, a diagnosis of pregabalin- and azithromycin-induced rhabdomyolysis was made. DISCUSSION: The long-term use of pregabalin and the initiation azithromycin therapy followed by a rapid onset of rhabdomyolysis is indicative of a drug interaction between pregabalin and azithromycin. CONCLUSION: We report an extremely rare case of rhabdomyolysis with purpura caused by a drug interaction between pregabalin and azithromycin. However, the mechanisms of the interactions between azithromycin on the pregabalin are still unknown.

RESUMO

BACKGROUND: Despite the widespread use of percutaneous endoscopic gastrostomy (PEG) tubes, their placement may be associated with a variety of complications, including gastrocolic fistula. METHODS: In total, 48 individuals underwent computed tomography-gastro-colonography (CT-GC)-guided PEG placement. Study end points included success of CT-GC, inability to thread the PEG tube, the eventual tube location, tube adjustments needed, adverse events, operating time, and PEG tube-related infection. RESULTS: A successful CT-GC was achieved in all 48 patients (100%), and we successfully used a standard PEG technique to place the gastrostomy tube in 44 patients (92%). In 4 patients (8%), the laparoscopic-assisted PEG technique was used because the transverse colon became interposed between the abdominal wall and the anterior wall of the stomach. The overall procedure-related minor complication rate was 8%. CONCLUSION: CT-GC is an optional method for the estimation of intra-abdominal, anatomical orientations that may minimize the risk of complications before PEG placement.

RESUMO

INTRODUCTION: Rhabdomyolysis associated with the use of pravastatin has been demonstrated to be a rare but potentially life-threatening adverse effect of statins. Here, we report a rare case of rhabdomyolysis and purpura fulminans in a patient who had used pravastatin and developed chronic renal failure (CRF) necessitating the initiation of dialysis. PRESENTATION OF CASE: We present the case of an 86-year-old man with chronic kidney disease (CKD) treated with dialysis who was admitted with back pain. He was prescribed and took pravastatin for almost 3 years to treat hyperlipidemia. He received hemodialysis therapy 7 times prior to presentation. Laboratory values included a serum creatine concentration of 6.6mg/dl and a creatinine phosphokinase (CPK) concentration of 2350IU/L. An abdominal computed tomography scan showed swollen muscles with reduced muscle density and air density in the multifidus muscle. Two days after admission, he had large, tender ecchymotic lesions and purpuric progressive skin necrosis over the back, abdomen, and upper and lower extremities. The patient died 6 days after the initial admission due to disseminated intravascular coagulation (DIC). Based on these findings and the clinical history, a diagnosis of pravastatin-induced rhabdomyolysis and purpura fulminans was made. DISCUSSION: The long-term use of statin therapy and the initiation of dialysis therapy due to ESRD, followed by a rapid onset of rhabdomyolysis within 6 days, is indicative of an elevated statin concentration. CONCLUSION: We report an extremely rare case of pravastatin-induced rhabdomyolysis and purpura fulminans with DIC in a patient with CRF.

RESUMO

INTRODUCTION: Protein induced by vitamin K absence/antagonist-II (PIVKA-II) is an abnormal protein, and several reports have demonstrated the efficacy of PIVKA-II in the diagnosis of hepatocellular carcinoma (HCC). We report an extremely rare case of adenocarcinoma of the colon with a high serum PIVKA-II level. PRESENTATION OF CASE: A 95-year-old woman presented with right lower quadrant pain and appetite loss. An abdominal computed tomography scan and ultrasonography showed an ascending colon tumor and multiple metastatic tumors in the liver. The serum level of PIVKA-II was extremely high, 11,900ng/mL. Colonoscopic examination revealed a tumor accompanied by an ulcer in the ascending colon, which was highly suspicious for malignancy. Multiple biopsies showed well-differentiated adenocarcinoma of the colon, which was evaluated as colon cancer, stage IV. PIVKA-II-productive colon cancer was confirmed. Chemotherapy with TS-1 was administered. The patient died 3 months after initial admission. DISCUSSION: The expression of PIVKA-II was detected in non-cancer areas, with non-specific expression observed in plasma cells in our case. There might be some possibility that hepatoid differentiation exists in other regions of the colon tumor or in the liver tumor, parenchymal cells or lung metastases, which were composed of PIVKA-II-positive and AFP-negative cells. CONCLUSION: To the best of our knowledge, high serum levels of PIVKA-II resulting from colon adenocarcinoma have not been reported previously. We report this rare case together with a review of the literature.

RESUMO

BACKGROUND AND PURPOSE: The objective of this study was to determine the success rate and complications of using the percutaneous approach of the external jugular vein (EJV) for placement of a totally implantable venous-access port (TIVAP) with a preoperative estimate of the detailed anatomical orientation of the cervical venous plexus using computed tomography venography (CT-V). METHODS: A prospective cohort study of 45 patients in whom placement of a TIVAP was attempted via the right EJV was conducted. The preoperative anatomical estimation of the cervical venous plexus was performed with CT-V using a Multidetector Helical 16-section CT. The angulation between the right EJV and the right subclavian vein, anterior jugular vein, transverse cervical vein, and suprascapular vein was estimated. RESULTS: CT-V success was achieved in 45 of 45 patients (100 %). A plexus of veins under the clavicle was most commonly responsible for the insertion of the central venous catheter. The EJV approach resulted in a successful cannulation rate of 93 %. No initial complications of pneumothorax or carotid artery puncture occurred during insertion procedures. Late complications occurred in three patients. These included one port erosion (2 %), one catheter occlusion (2 %), and one wound hematoma (2 %). Catheter-related infections were observed in one patient (2 %). CONCLUSIONS: The percutaneous EJV approach with CT-V guidance is an optional method for patients with multiple central venous cannulations, those in hemodialysis, or those with long catheter indwelling periods.

RESUMO

OBJECTIVE: To determine the success rate and complications of using the external jugular vein (EJV) for central venous access with a preoperative estimate of the detailed anatomical orientation of the cervical venous plexus using computed tomography venography (CT-V). DESIGN: Prospective, observational human study. SETTING: Surgical intensive care unit. PATIENTS: Fifty-two patients who were undergoing EJV cannulations with CT-V using a Multidetector Helical 16-section CT (MDCT). INTERVENTION: The preoperative anatomical estimation of the cervical venous plexus was performed with CT-V using an MDCT. In particular, the angulation between the EJV and the right subclavian vein (SCV) was measured. The anatomical abnormalities and the angulation between the EJV and the anterior jugular vein (AJV), transverse cervical vein (TCV), and suprascapular vein (SSV) were estimated. MEASUREMENTS AND MAIN RESULTS: The success of CT-V was achieved in 52 of 52 patients (100%). The mean angulation between the right EJV and the right SCV was 144 ± 36 degrees in the obtuse-angle cases (88%) and 72 ± 28 degrees in the sharp-angle cases (12%). A plexus of veins under the clavicle was most commonly responsible for insertion of the central venous catheter (CVC). The EJV approach resulted in a 93% rate of successful cannulations. No complications of pneumothorax or carotid artery puncture occurred during insertion procedures. CONCLUSIONS: The EJV route is associated with comparable technical success and lower major procedural complication. The EJV approach with CT-V guidance is an option as the initial method when central venous cannulation must be performed under suboptimal conditions.

RESUMO

Rhabdomyolysis associated with fenofibrate monotherapy is extremely rare. Here, we report a rare case of rhabdomyolysis of the psoas muscle in an 82-year-old man with chronic myelogenous leukemia (CML). He was prescribed fenofibrate because of a hypertriglyceridemia. The patient reported generalized muscle pain and right abdominal pain while receiving fenofibrate monotherapy. An abdominal computed tomography scan and an abdominal ultrasound showed a large and low attenuation and high echogenicity, respectively, in the right middle abdominal area. Laboratory values included a serum creatine concentration of 4.1 mg/dl and a creatinine phosphokinase concentration of 5,882 IU/l. During laparotomy, a large hematoma and necrotic mass was identified in the right psoas muscle. Histological examination revealed that the resected specimens were of the psoas muscle with irregular fiber sizes, degenerating fibers surrounding the inflammatory reaction, and fiber necrosis that is typical for polymyositis. Based on these findings and the clinical history, a diagnosis of fenofibrate-induced rhabdomyolysis was made. To the best of our knowledge, no patient has ever been diagnosed with fulminant psoas rhabdomyolysis due to a fenofibrate monotherapy. This report details the rare case of rhabdomyolysis in a patient with CML associated with fenofibrate monotherapy and offers a review of the literature.

RESUMO

Carbohydrate antigen 19-9 (CA 19-9) is a sensitive marker for pancreatic and hepatobiliary malignancies. The highest frequency of elevated serum CA 19-9 levels is found among patients with pancreatic cancer. CA 19-9 has recently been demonstrated to be a marker of digestive tract malignancies. We report the case of a patient with a gastric cancer and a very high serum CA 19-9 level. During laparotomy, a large mass was found in the antrum. A distal gastrectomy with D2 dissection of the lymph nodes was performed. Histological examination, including immunohistochemistry, revealed an adenocarcinoma of the stomach producing CA 19-9. To the best of our knowledge, no patient with an extremely high serum CA 19-9 level resulting from a gastric adenocarcinoma has been reported previously.
