RESUMO

A 49-year-old man visited the emergency room of Korea University Ansan Hospital with hematochezia starting the day before the visit. Recently, he was on anti-platelet medication due to hypertension. The patient had no definite symptoms other than hematochezia. Digital rectal exam was positive and laboratory tests showed severe anemia. Sigmoidoscopy was initiated and almost no fecal material was observed in the intestinal tract, allowing insertion into the cecum. Active bleeding from the appendiceal opening was noted. On abdominal CT, contrast enhancement was observed at the tip of the appendix. Under suspicion of acute appendicitis, we consulted with a surgeon. The patient underwent appendectomy with partial cecal resection. Pathologic examination revealed a diagnosis of appendix bleeding due to acute suppurative appendicitis. The patient had no further bleeding after surgery and was discharged in a stable state. Careful observation by the endoscopist is necessary for accurate diagnosis of lower gastrointestinal hemorrhage. Appendiceal hemorrhage is very rarely reported, but it has various pathophysiologies. CT scan is useful when appendiceal hemorrhage is confirmed by endoscopic findings. Surgical treatment was needed in almost all cases reported worldwide. If bleeding from the appendix is confirmed, surgical treatment should be considered for both therapeutic and diagnostic purposes.

RESUMO

A 54-year old man diagnosed with advanced hepatocellular carcinoma began treatment with sorafenib. After 3 weeks of treatment, he complained of abdominal pain and nausea. Abdominal sonography showed multiple hepatic lesions only. Serum amylase and lipase levels were 35 U/L and 191 U/L, respectively. The patient was diagnosed with sorafenib-induced acute pancreatitis. After 10 days of discontinuing sorafenib he still complained of nausea and loss of appetite. Esophagogastroduodenoscopy showed a large bulging lesion, which was suspected to cause extrinsic compression on the high body of the gastric anterior wall. Computed tomography scan revealed a cystic lesion, 8.3 cm in size, in the pancreatic tail, suggesting a pancreatic pseudocyst. After the withdrawal of sorafenib, systemic chemotherapy with Adriamycin and cisplatin was administered. Four months after the discontinuation of sorafenib, the size of the pancreatic pseudocyst decreased from 8.3 cm to 3 cm. The patient's symptoms were also relieved.

RESUMO

Ultrasound diathermy is widely used for the treatment of musculoskeletal disorders and other soft tissue injuries. Its use as a therapeutic modality is believed to be safe, with very few reported complications. Here, we report two patients who developed focal bone marrow abnormalities after receiving ultrasound diathermy. Both patients' magnetic resonance (MR) evaluations revealed linear subchondral bone lesions of the superolateral humeral head similar to those in osteonecrosis. The patients' symptoms subsequently improved, and available follow-up MR evaluation revealed near complete resolution of bone lesions. These findings suggest that ultrasound diathermy, and its interaction with bone tissue through thermal mechanisms, can cause focal bone marrow abnormalities. Furthermore, the bone marrow abnormalities seem to be transient, resolving upon cessation of ultrasound diathermy, therefore osteonecrosis should be differentiated from this temporal lesion.

RESUMO

Esophageal mucosal tear occurred during scope insertion in a 71-year-old male patient who previously underwent endoscopic retrograde cholangiopancreatography (ERCP) several times without any complications. The mucosal tear was successfully sealed with endoclips using a forward-viewing scope. However, this mishap leads to the incidental discovery of both esophageal cancer and early gastric cancer. Duodenoscope has inherent limitation in observing the gastrointestinal tract, especially the esophagus, and may miss clinically significant lesions. Therefore, in addition to applying sufficient lubricant to the scope tip and considering the possibility of anatomical variation to prevent mucosal injury or perforation, performing upper endoscopy during ERCP should be considered in a certain patient population, albeit the utility of and the population benefiting from it remains to be proven by a large-scale study.

RESUMO

BACKGROUND/AIMS: Several previous studies suggest that eradication of Helicobacter pylori (H. pylori) leads to the disappearance of gastric hyperplastic polyps. However, little is known about the effect of H. pylori status and eradication on the recurrence of gastric polyps after endoscopic removal. Here, we investigated the recurrence of gastric polyps according to the final H. pylori status in patients who underwent endoscopic removal of gastric hyperplastic polyps. METHODS: Between January 2011 and December 2016, patients who underwent endoscopic removal of gastric hyperplastic polyps and were followed-up for more than two months were enrolled. The success of H. pylori eradication was assessed by histology and rapid urease test or urea breath test, at least 4 weeks after the completion of eradication treatment. At follow-up, the recurrence of gastric polyp was evaluated via esophagogastroduodenoscopy. RESULTS: Seventy-nine patients were enrolled. During the mean follow-up period of 16.4 months, the recurrence rate of gastric polyp was 25.3%. Among those who received H. pylori eradication therapy, the H. pylori persistent group showed a higher recurrence of polyp than the H. pylori eradicated group; but there was no statistical significance (42.9% vs. 21.7%, p=0.269). Regarding the final H. pylori infection status, the recurrence rate of gastric polyps was significantly higher in the H. pylori positive group than in the H. pylori negative group (42.9% vs. 18.9%, p=0.031). In multivariate analysis, the final H. pylori infection status was a significant risk factor for gastric polyp recurrence after endoscopic removal. CONCLUSIONS: The final positive H. pylori infection status is significantly associated with higher recurrence of gastric hyperplastic polyps after endoscopic removal.

RESUMO

BACKGROUND: In general, the outcomes of arthroscopic repair for superior labrum anterior to posterior lesions (SLAP) are favorable, however, persistent pain and limitation of motion are not rare complications. One of the possible cause is a “knot-ache”. This study evaluated the results of reoperation of symptomatic recurrent SLAP lesions and asked whether the knot is associated with postoperative complications. METHODS: Between 2005 and 2015, a total of 11 patients who had undergone arthroscopic SLAP repair were reoperated for recurrent symptomatic SLAP lesion. By retrospective chart review, operative findings, the visual analogue scale for pain (pVAS), the range of motion (ROM), and functional scores were analyzed. RESULTS: The mean age of the study participants was 38.3 years, and the mean follow-up period was 42.5 months. In the primary operation, there were nine cases of repairs with conventional knot-tying anchors and three cases with knotless anchors. Impingement of the knots during abduction and external rotation of the shoulder was observed in the all cases with knot-tying anchors. The mean pVAS, ROM, and functional scores significantly improved with reoperation. At the final follow-up, the mean satisfaction VAS was 8.3. CONCLUSIONS: The knots of suture anchor maybe a possible etiology of the pain, which we termed a “knot-ache”. Considering that reoperation is performed due to pain after primary repair, the use of knotless suture anchor may have benefits of eliminating one of possible cause, “knot-ache”. Therefore, authors suggest the use of knotless anchors during reoperation for recurrent or recalcitrant pain after primary SLAP repair.

RESUMO

Tenofovir disoproxil fumarate (TDF) is one of the most widely used treatment options for human immunodeficiency virus (HIV) and HBV infections. Despite its efficacy and safety, some cases of nephrotoxicity have been reported in the treatment of HIV patients. Even more recently, very few cases of Fanconi syndrome associated with tenofovir therapy in HBV monoinfection have been reported. Herein, we report a case of a 47-year-old male with an HBV monoinfection, who developed Fanconi syndrome and a secondary osteomalacia with multiple bone pain. After TDF withdrawal and supplementation of calcitriol, his renal function was reverted. Although the overall risk of TDF-associated nephrotoxicity is very low, both glomerular and tubular function should be monitored in patients undergoing TDF treatment.

RESUMO

Sorafenib is a multi-targeted tyrosine kinase inhibitor that inhibits Raf kinase and the vascular endothelial growth factor receptor intracellular kinase pathway and is the first agent to demonstrate a statistically significant improvement in overall survival for patients with advanced hepatocellular carcinoma (HCC). However, there were few cases of partial or complete response reported in the previous studies. We herein report a case of dramatic partial response in a patient who had advanced HCC with multiple lung metastasis and portal vein thrombosis treated with sorafenib.

RESUMO

OBJECTIVE: To compare the effects of lumbar stabilization exercises and lumbar dynamic strengthening exercises on the maximal isometric strength of the lumbar extensors, pain severity and functional disability in patients with chronic low back pain (LBP). METHODS: Patients suffering nonspecific LBP for more than 3 months were included prospectively and randomized into lumbar stabilization exercise group (n=11) or lumbar dynamic strengthening exercise group (n=10). Exercises were performed for 1 hour, twice weekly, for 8 weeks. The strength of the lumbar extensors was measured at various angles ranging from 0degrees to 72degrees at intervals of 12degrees, using a MedX. The visual analog scale (VAS) and the Oswestry Low Back Pain Disability Questionnaire (ODQ) were used to measure the severity of LBP and functional disability before and after the exercise. RESULTS: Compared with the baseline, lumbar extension strength at all angles improved significantly in both groups after 8 weeks. The improvements were significantly greater in the lumbar stabilization exercise group at 0degrees and 12degrees of lumbar flexion. VAS decreased significantly after treatment; however, the changes were not significantly different between the groups. ODQ scores improved significantly in the stabilization exercise group only. CONCLUSION: Both lumbar stabilization and dynamic strengthening exercise strengthened the lumbar extensors and reduced LBP. However, the lumbar stabilization exercise was more effective in lumbar extensor strengthening and functional improvement in patients with nonspecific chronic LBP.

RESUMO

BACKGROUND: This study was performed to investigate the relationship between coronal computed tomography (CT) and Broden's view in terms of location of the fracture line and fracture pattern. METHODS: Forty-five feet of 45 patients with intraarticular calcaneal fractures were evaluated. The mean age of the patients was 46.3 years (standard deviation, 18.1; range, 15 to 80 years), and there were 34 men and 11 women. The Broden's views were acquired using the ray sum projection, reviewed, and correlated with the coronal CT image to determine the location of the fracture on the posterior facet and fracture pattern described by the Sanders classification. The quantified location of the fracture line was defined as the distance between the medial margin of posterior facet and the fracture line divided by the whole length of the posterior facet, which was expressed as a percentage. RESULTS: The fracture line on the Broden's view was positioned at 22.3% (standard deviation, 29.6) laterally compared to that on coronal CT (p < 0.01). Although all cases showed posterior facet involvement on the CT scan, the fracture line was positioned lateral to the posterior facet in 6 cases (13.3%) in the Broden's view. The coronal CT and Broden's view showed a low level of agreement in the fracture pattern according to the Sanders classification, with kappa values of 0.23. CONCLUSIONS: Surgeons should consider that the fracture line on the Broden's view shows positioning laterally compared to coronal CT and they should consider that the fracture line at the lateral to posterior facet on the Broden's view might be an intraarticular fracture line. There are some limitations when applying the Sanders classification with the Broden's view.

RESUMO

OBJECTIVE: To investigate the inter-rater agreement using the Videofluoroscopic Dysphagia Scale (VDS). METHOD: The present study was designed as a multicenter, single-blind trial. A Videofluoroscopic Swallowing Study (VFSS) was performed using the protocol described by J.A Logemann. Thick-fluid, pureed food, mechanically altered food, regularly textured food, and thin-fluid boluses were sequentially swallowed. Each participant received a 3 ml bolus followed by a 5 ml bolus of each food material, in the order mentioned above. All study procedures were video recorded. Discs containing these video recordings in random order were distributed to interpreters who were blinded to the participant information. The video recordings were evaluated using a standardized VDS sheet and the inter-rater reliability was calculated. RESULTS: In total, 100 patients participated in this study and 10 interpreters analyzed the findings. Inter-rater reliability was fair in terms of lip closure (kappa: 0.325), oral transit time (0.253), delayed triggering of pharyngeal swallowing (0.300), vallecular residue (0.275), laryngeal elevation (0.345), pyriform sinus residue (0.310), coating of the pharyngeal wall (0.310), and aspiration (0.393). However, other parameters of the oral phase were lower than those of the pharyngeal phase (0.06-0.153). Moreover, the summation of VDS reliability (intraclass correlation coefficient: 0.556) showed moderate agreement. CONCLUSION: VDS shows a moderate rate of agreement for evaluating the swallowing function. However, many of the parameters demonstrated a lower rate of agreement, particularly the oral phase parameters.

RESUMO

PURPOSE: To identify the effects of using a Ti-Ni shape memory alloy ring shaped bone fixator (SMA-rBF) during the retrograde nailing of supracondylar femoral fractures. MATERIALS AND METHODS: The authors reviewed 25 patients with a supracondylar femoral fracture treated by retrograde intramedullary nailing with or without SMA-rBF (group S, 12/25; group N, 13/25). Radiological measurements of angular deformity were performed and functional assessments were made using the Sanders grading system. RESULTS: All fractures healed after an average of 12.2 weeks (range, 9-15 weeks) in group N and after 11.6 weeks (range, 10-13 weeks) in group S (p=0.351). The mean angle of coronal angular deformity was valgus 0.8degrees (range, varus 2.3degrees-valgus 4.5degrees) in group N and valgus 0.7degrees (range, varus 1.0degrees-valgus 2.4degrees) in group S (p=0.892). The mean angle of sagittal angular deformity was 1.0degrees in extension (range, flexion 3.2degrees-extension 3.1degrees) in group N and 0degrees (range, flexion 2.1degrees-extension 1.2degrees) in group S (p=0.022). However, functional grading evaluations revealed no differences between the two groups. CONCLUSIONS: When reduction of a distal femoral fracture with retrograde nailing was difficult additional mini-open reduction and fixation with a ring shaped SMA did not delay or prevent bony union and resulted in good postoperative alignment.

RESUMO

Total exchangeable sodium and plasma volume were measured to evaluate role of sodium in hypertension by radioisotope 24 Na and Evans blue in 25 patients with essential hypertension, 10 with malignant hypertension, 5 with renal hypertension and 15 normal controls. The results obtained are as follows. 1. The total exchangeable sodium content was 35.8+/-3.5mEq/kg in normal controls, 35.6+/-2.7mEq/kg in essential hypertension and 36.2+/-3.5mEq/kg in renal hypertension revealing no statistical significance in difference. In malignant hypertension, it was 44.9+/-2.0mEq/kg and it was markedly elevated than in normal controls. 2. Plasma volume in normal controls was 44.0+/-4.7ml/kg. In essential hypertension there was two groups, one (group II, 35.2+/-5.6ml/kg) was slightly lower than the other (group I, 43.2+/-4.8ml/kg). In malignant hypertension, it was 56.9+/-7.5ml/kg revealing significant increase than in normal controls. 3. Changes of the total exchangeable sodium content was observed after the administration of hydrochlorothiazide 50mg in normal controls and essential hypertension. In normal controls there was no statistical significance in reduction. In essential hypertension, initially low salt group (group II) showed no significant reduction and the other group (group I) showed significant reduction with depression on blood pressure. 4. Long term therapy with hydrochlorothiazide 50mg for 2~3 months in the group of hypertension who responded well with short term therapy (group I), the contents of exchangeable sodium reduced significantly than normal controls and the antihypertensive effect was sustained. 5. The reduction of plasma volume with hydrochlorothiazide in essential hypertension are similar as changes of total exchangeable sodium. 6. In cases of low salt diet 4gm of daily salt intake, there was similar results as diuretic therapy in exchangeable sodium. 7. In patients who responded well to antihypertensive effect of hydrochlorothiazide or low salt diet (group I), salt loading of 10gm daily showed an increase of total exchangeable sodium and an elevation of blood pressure with statistical significance.

RESUMO

Extraadrenal pheochromocytomas developed from the paraganglia other than adrenal medulla are uncommon tumors. Such lesions have been reported that as much as 10% of retroperitoneal paragliomas arise outside the adrenal gland. But their incidence and prognosis are changing partly as a result of progression in developmental mechanism, diagnostic tools and concepts including ultrastructure, immunohistochemistry. The ultrastructure of chromaffine neoplasm from adrenal and extraadrenal tissues has been studied with chrarnaffine granule specificity and type of catecholamine content. With rare exceptions, extraadrenal chrornaffine tumor mainly has high concentration of norepinephrine which is suggested as dict relationship to numoruos electrone dense granular bodies in the cell cytoplasrn. High or intermediate level of epinephrine in tissue is associated with cytoplasmic granular bodies of much less density, Recently we experienced the exception, a case of norepinephrine secreting pheochrom-ocytoma in the organ of Zuckerkandl with epinephrine granules in cytoplasm and this discrepancy probably due to the plasticity
