    ABSTRACT: Contributing reviewers A peer-reviewed journal would not survive without the generous time and insightful comments of the reviewers, whose efforts often go unrecognized. Although final decisions are always editorial, they are greatly facilitated by the deeper technical knowledge, scientific insights, understanding of social consequences, and passion that reviewers bring to our deliberations. For these reasons, the Editor-in-Chief and staff of the journal warmly thank the 906 reviewers whose comments helped to shape Journal of Medical Case Reports, for their invaluable assistance with review of manuscripts for the journal in Volume 8 (2014).

    ABSTRACT: Solitary fibrous tumors are rare neoplasms of mesenchymal origin. They are often of low malignant potential and rarely metastasize. While they frequently arise from the pleura, they can occur at any soft tissue site in the body. We present a case of a large (28 × 21cm) malignant solitary fibrous tumor arising from the bladder serosa. In addition, the clinicopathologic features, differential diagnosis, cytogenetics and management of this rare disease are discussed, along with a review of the existing literature on this topic. An otherwise healthy 41-year-old Caucasian man presented with weight loss and progressive abdominal bloating. A subsequent computed tomography scan of his chest, abdomen and pelvis revealed a 26.8 × 21cm intra-abdominal mass occupying most of his abdominal cavity. The inferior vena cava was compressed, and the mass extended inferiorly to his upper pelvis abutting the superior dome of his bladder. He underwent operative resection and the resected mass measured 28 × 21 × 18cm and weighed 4.8kg. The cut surface revealed a gray-white mass with an ill-defined whorled-like pattern, with randomly assorted tan fleshy nodules. A histologic evaluation revealed variable, alternating hypercellular and hypocellular areas, with areas of necrosis. The tumor cells varied from spindle to epithelioid within a hyalinized stroma. In the hypercellular areas, the tumor cells showed moderate atypia with high mitotic activity. The histological features combined with immunophenotyping were suggestive of a malignant solitary fibrous tumor that grossly appeared to be growing from the bladder serosa, specifically the intraperitoneal superior dome of the bladder. Our patient is currently eight months post-surgery without evidence of recurrence. Extrapleural occurrences of solitary fibrosis tumors are being increasingly observed. Malignant solitary fibrosis tumors of the urinary bladder, however, are very rare. As there are no pathognomonic features of malignancy, surgical resection is often both diagnostic and therapeutic, as was the case in our report.

    ABSTRACT: Introduction Ureteral atresia is a rare disease usually associated with a non-functioning kidney. Its association with other urinary anomalies is rare. Case presentation In this study we discuss the possibility of congenital or acquired etiology of a right imperforate distal ureter. Here we report the case of 11-month-old white boy with a right ureteropelvic junction obstruction. He underwent a right pyeloplasty when he was 11-months old, and 3 weeks after surgery a cystoscopy was performed. Two months after the first operation, he underwent a right ureteral meatoplasty and a new pyeloplasty. Conclusions To the best of our knowledge, few cases of imperforate distal ureter have been described in the literature. The suspicion of a non-patent terminal ureter, occurring during upper urinary tract surgery, must be intraoperatively clarified to preserve the renal function and to avoid more complex surgical approaches.

    ABSTRACT: Pleural effusion induced by sarcoidosis is rare, and pleural sarcoidosis is often diagnosed by thoracoscopic surgery. The diagnosis of pleural sarcoidosis using thoracentesis may be less invasive when sarcoidosis is already diagnosed histologically in more than one organ specimen. Here we report the case of a 64-year-old woman with pleural sarcoidosis diagnosed on the basis of an increased CD4/CD8 lymphocyte ratio in pleural effusion fluid obtained by thoracentesis. This case report is important because it highlights the usefulness of the CD4/CD8 lymphocyte ratio in pleural effusion as an indicator of pleural involvement of sarcoidosis. A 64-year-old Japanese woman visited our hospital with an initial symptom of dyspnea on exertion for a period of 4 months. Chest computed tomography showed bilateral hilar and multiple mediastinal lymphadenopathy, multiple small nodular shadows in her bilateral lungs, small nodular shadows along the interlobar pleura, and bilateral pleural effusion. Her serum angiotensin-converting enzyme and soluble interleukin-2 receptor levels were elevated. Histological analysis of a resected subcutaneous nodule, and biopsy specimens from a right mediastinal lymph node and from her right lung revealed non-caseous epithelioid granulomas. Her bronchoalveolar lavage fluid exhibited a predominance of lymphocytes together with an increase in the CD4/CD8 lymphocyte ratio. The lymphocytic predominance and the increased CD4/CD8 lymphocyte ratio were also detected in the right-sided pleural effusion fluid obtained by thoracentesis. We diagnosed sarcoidosis with pleural involvement. Because pleural effusion did not resolve spontaneously and her symptom of dyspnea on exertion worsened, corticosteroid therapy was initiated, which ameliorated the sarcoidosis and the pleuritis. Analysis of the CD4/CD8 lymphocyte ratio in pleural effusion fluid obtained by thoracentesis may be helpful for the diagnosis of pleural sarcoidosis when the diagnosis is already made by histological examination of more than one organ specimen.

    ABSTRACT: Henoch–Schönlein purpura is an immunoglobulin A-mediated, small vascular inflammatory disease that can be associated with palpable purpura, arthralgia, abdominal pain, or nephritis. The presence of purpura facilitates the diagnosis of Henoch–Schönlein purpura at the onset of associated symptoms, whereas the absence of purpura makes the diagnosis challenging. It is important to diagnose Henoch–Schönlein purpura with delayed-onset skin purpura to avoid unnecessary surgery for acute abdomen. Most cases of Henoch–Schönlein purpura with severe abdominal pain are treated with low-dose steroids and intravenous immunoglobulin. Case presentation A 15-year-old Korean girl complained of severe abdominal pain and delayed-onset purpura on admission. Henoch–Schönlein purpura was diagnosed based on endoscopic findings of hemorrhagic duodenitis and duodenal vasculitis and abdominal computed tomography findings of edematous bowels. Two common initial treatments, a low-dose steroid and intravenous immunoglobulin, were administered, but there was no improvement for 1 month. Subsequently, we used high-dose intravenous methylprednisolone pulse therapy (30mg/kg/day, with a maximum of 1g/day), which dramatically alleviated her abdominal symptoms. High-dose intravenous methylprednisolone pulse therapy can be used as the ultimate treatment for delayed-onset Henoch–Schönlein purpura with severe abdominal pain when symptoms do not improve after low-dose steroid and intravenous immunoglobulin treatments.

    ABSTRACT: Bronchial arteries originate from the descending aorta at the level of the T5-T6 vertebrae following an intrapulmonary course along the major bronchi. When bronchial arteries take off from a vessel other than the descending aorta, the anatomy is defined as an anomalous origin of the bronchial artery. A 3-day-old boy from Kosovo with dextro-transposition of the great arteries who developed progressive heart failure required an emergency arterial switch operation. Because of persistent pulmonary edema after completion of the arterial switch operation at our institution, the patient could not be weaned off mechanical ventilation. Transthoracic echocardiography revealed an anomalous accelerated flow, indicating an anomalous systemic pulmonary shunt. Arterial catheterization revealed an abnormal bronchial artery originating from the left subclavian artery and bifurcating to both lungs. The anomalous ectatic bronchial artery was successfully occluded by coil embolization. The improvement of the patient's hemodynamic status resulted in an uneventful post-operative course. A coil embolization procedure was successfully performed to treat an anomalous bronchial artery originating from the left subclavian artery after a switch operation in a patient with transposition of the great arteries. When clinically indicated, catheter-based therapy with coil embolization can be performed to successfully treat anomalous bronchial arteries by reducing as such the pulmonary overflow.

    ABSTRACT: Here we present our clinical experience in a case of esophagus perforation due to the swallowing of a bone piece causing acute angina pectoris and leading to misdiagnosis of acute coronary syndrome. A 73-year-old Caucasian man underwent urgent coronary angiography with possible diagnosis of acute coronary syndrome. His coronary arteries were found to be normal. A computed tomography examination revealed esophagus perforation by a foreign body (a piece of bone), and he underwent urgent left thoracotomy and the foreign body was removed. Sometimes, even a piece of bone within a meal can lead to esophagus perforation, and injure the pericardium and myocardium. The symptoms of esophagus perforation may be confused with acute coronary syndrome due to their similarities and lack of knowledge about the detailed clinical history as shown in our case. Thus, careful consideration of detailed clinical history as well as choosing an appropriate medical imaging modality, such as computed tomography, should always be kept in mind in order to promptly diagnose and start early treatment to reduce mortality.

    ABSTRACT: Hepatic encephalopathy is an important underlying cause of consciousness disorders. Possible causes of hepatic encephalopathy include hepatic failure and shunt encephalopathy resulting from a portosystemic venous shunt. Balloon-occluded retrograde transvenous obliteration is generally an effective treatment for hepatic encephalopathy. Case presentation A 73-year-old Japanese woman was referred to our department because of disturbance of consciousness. Hepatic venous angiography disclosed a shunt between her left hepatic vein and her portal vein. The shunt was closed with the use of coils and N-butyl 2-cyanoacrylate. One hour after the procedure, she lost consciousness. The bleeding was ascribed to catheter-induced vascular injury. Emergency angiography was performed, and hemostasis was achieved with coils. Although bleeding is relatively rare after balloon-occluded retrograde transvenous obliteration, postoperative intraperitoneal bleeding is a serious complication.

    ABSTRACT: Usher syndrome is a genetically heterogeneous condition and represents the most common cause of inherited combined vision and hearing loss. Deficits manifest as sensorineural hearing loss that typically develops at a young age and retinitis pigmentosa that can lead to peripheral vision loss and night blindness. As a result, this syndrome can have a significant impact on a patient's quality of life. Previous studies have described an association between Usher syndrome and Fuchs' heterochromic iridocyclitis, a form of non-granulomatous uveitis that generally presents in a unilateral manner. We present a rare finding of bilateral uveitis and, to the best of our knowledge, the first report of granulomatous uveitis as a feature in a patient with Usher syndrome. A 45-year-old Caucasian woman with a known history of retinitis pigmentosa presented to our clinic with suspected Usher syndrome, given her report of long-standing hearing loss. Aside from a mild loss in visual acuity, our patient was otherwise asymptomatic. Visual field testing, audiology and electroretinography findings supported the diagnosis of Usher syndrome. With slit lamp examination she was found to have bilateral keratic precipitates, with large, greasy-white, mutton-fat keratic precipitates on the endothelial surface of her left eye. A thorough work-up that included blood tests and imaging was negative for an alternative cause of her uveitis. We present a rare finding of bilateral uveitis and what we believe to be the first reported instance of mutton-fat keratic precipitates and granulomatous uveitis as a feature in a patient with Usher syndrome. By identifying atypical presentations of the disease, we hope to contribute to the range of ophthalmic conditions that may be seen in association with Usher syndrome.
