Spontaneous rupture of non-parasitic hepatic cyst

INTERNATIONAL JOURNAL OF CLINICAL PRACTICE, Issue 1 2006
G. Poggi
Summary Intrahepatic cysts are generally classified as congenital, traumatic, infectious or neoplastic. Non-parasitic hepatic cysts (NPHCs) include simple cysts and adult polycystic liver disease in which the liver is diffusely occupied by cysts. NPHCs usually reach a large size before causing symptoms, unless a complication such as rupture, bleeding, infection, obstructive jaundice or neoplastic transformation occurs. We report the case of a 67-year-old man with spontaneous rupture of simple liver cyst. The clinical pictures and the unusual ultrasound features of this rare condition are discussed. [source]

Spontaneous rupture of the spleen as the presenting feature of the blastoid variant of mantle cell lymphoma

INTERNATIONAL JOURNAL OF LABORATORY HEMATOLOGY, Issue 4 2003
K. D. Mason
Summary Spontaneous splenic rupture is rare, and particularly so as the initial presentation of a lymphoproliferative disorder. Although rare cases of splenic rupture have been reported in mantle cell lymphoma there has not been a report of the blastoid variant presenting in this manner. We report such a case in a 64-year-old man. [source]

Spontaneous rupture of varicocele testis associated with advanced pancreatic cancer

INTERNATIONAL JOURNAL OF UROLOGY, Issue 12 2004
YOSHIYUKI MATSUI
Abstract, We report a rare case of strain-induced spontaneous rupture of varicocele associated with renal vein involvement by advanced pancreatic cancer. Computed tomography and color Doppler sonography yielded the correct diagnosis and the patient could maintain quality of life without surgery for acute scrotum. [source]

Honoring the Admiral: Boerhaave-van Wassenaer's syndrome

DISEASES OF THE ESOPHAGUS, Issue 3 2006
B. D. Adams
SUMMARY., Dr. Herman Boerhaave (1668,1738) first described esophageal rupture and the subsequent mediastinal sepsis based upon his careful clinical and autopsy findings and hundreds of references have since been written about Boerhaave's syndrome. Several fine historical accounts of this brilliant scientist have been published over the years and he has received appropriate credit for his valuable contributions. But what about that unfortunate propositus that Dr. Boerhaave attended to, performed necropsy upon, and subsequently received acclaim with? Medical history pays inadequate regard to the Baron Jan Gerrit van Wassenaer heer van Rosenberg, Prefect of Rhineland and Grand Admiral of the Dutch Fleet. This figure was a nobleman and war hero at the peak of the Dutch Golden Age who played his role in steering the course of European history. Without this nobleman's heroic contemporaneous account, Boerhaave's celebrated impact on medical science would never have been realized. Therefore, we offer an overdue recitation of Admiral van Wassenaer's biography. Based on found precedent we propose that spontaneous rupture of the esophagus be henceforth referred to as the ,Boerhaave-van Wassenaer's syndrome'. [source]

Ultrasonographic detection of spontaneous rupture in the Biceps tendon of a patient with rheumatoid arthritis

INTERNATIONAL JOURNAL OF RHEUMATIC DISEASES, Issue 4 2007
Hyun-Sook KIM
Abstract Ultrasonography is a useful imaging modality for the diagnosis of pathologic conditions in the biceps tendon. We describe a 64-year old man with rheumatoid arthritis (RA) who suddenly developed a painless lump in the antecubital region of the right arm. The bulging was prominent when he flexed his forearm. Proximal loss of the long head in biceps tendon could be demonstrated by ultrasonography. The ultrasonographic features of spontaneous isolated biceps tendon rupture occurring in a patient with RA are described. [source]

Cardiac tamponade caused by spontaneous rupture of mediastinal lymph node metastasis of hepatocellular carcinoma

JOURNAL OF GASTROENTEROLOGY AND HEPATOLOGY, Issue 6 2001
Shuichi Seki
Abstract Rupture of a hepatocellular carcinoma (HCC) is a well-known cause of death in patients with HCC. This report describes a rare case of HCC presenting as cardiac tamponade caused by a spontaneous rupture of mediastinal lymph node metastasis into the pericardial space. A transcatheter arterial embolization (TAE) of internal thoracic artery successfully controlled the bleeding, and the patient was rescued from cardiac tamponade. Although there was no rebleeding, the patient died from liver failure 2 months later. An autopsy revealed a poorly differentiated HCC in the liver, lung and mediastinal lymph nodes. [source]

Nitric oxide metabolite levels in preterm labor

JOURNAL OF OBSTETRICS AND GYNAECOLOGY RESEARCH (ELECTRONIC), Issue 5 2007

Abstract Aim:, To investigate the role of nitric oxide metabolites as markers of infection in subjects with preterm labor or preterm premature rupture of membranes (PTPROM). PTPROM means that there was spontaneous rupture of fetal membrane before the onset of labor and gestational age was <37 weeks. This occurs because of imbalance between matrix metalloproteinase and tissue inhibitor of matrix metalloproteinase. The cause of this imbalance that leads to degradation of collagen causing PTPROM is infection. The bactericidal, fungicidal, viricidal and tumoricidal activities of macrophages are determined in part by elaboration of nitric oxide, hence nitric oxide levels have been found to be increased in infections Methods:, During an 18-month period 50 women with preterm labor or PTPROM and 50 controls were enrolled prospectively. Blood and urine samples were obtained for analysis of nitric oxide metabolites. Patients with known causes of preterm labor were excluded. Result:, The nitric oxide metabolites, which included both nitrite levels and citrulline levels were significantly higher both in blood as well as urine in patients with preterm labor and PTPROM compared to controls. Serum nitrite levels in subjects with preterm labor were 376.5 ± 345 nmol/L while in subjects with PTPROM they were 295.7 ± 161.1 nmol/L and in controls the levels were 62.7 ± 33.9 nmol/L. Serum citrulline levels in subjects with preterm labor were 5293.8 ± 2916.7 nmol/L; in PTPROM they were 6536.6 ± 609.91 nmol/L and in controls they were 949.8 ± 67.1 nmol/L. On comparing patients with preterm labor, those in whom preterm labor could not be inhibited had statistically significant higher levels of nitrite in both serum and urine (482.9 ± 387.7 nmol/L and 754.5 ± 336.5 nmol/L, respectively) compared to patients in whom labor could be inhibited (172.2 ± 61.9 nmol/L and 401.8 ± 236.9 nmol/L, respectively). The citrulline levels were also higher among the group who delivered preterm for both serum and urine (5355.4 ± 3229.7 nmol/L and 11 482.8 ± 2541.4 nmol/L, respectively) compared to patients in whom labor could be inhibited (5260.2 ± 2897.08 nmol/L and 10 651.4 ± 1502.7 nmol/L, respectively) but this did not reach statistical significance. Conclusion:, Higher nitric oxide metabolites in women with preterm labor are marker of subclinical infection. [source]

Structure of the human tibialis anterior tendon

JOURNAL OF ANATOMY, Issue 4 2000
WOLF PETERSEN
The structure and vascular pattern of the human tibialis anterior tendon was investigated using injection techniques, light and transmission electron microscopy and immunohistochemistry. From the well vascularised peritenon, blood vessels penetrate the tendon tissue and anastomose with a longitudinally oriented intratendinous network. The distribution of blood vessels within the tibialis anterior tendon was not homogenous. The posterior part of the tendon had a complete vascular network that extends from the musculotendinous junction to the insertion at the first metatarsal and medial cuneiform bones. In the anterior half, the tissue was avascular in a zone with a length of 45,67 mm. This zone was covered by a single layer (,30 ,m) of oval shaped cells. Transmission electron microscopy showed that these cells have the characteristics of chondroid cells. This region was stained by Alcian blue at pH 1 which indicates a high concentration of acid glycosaminoglycans and immunohistochemical staining for chondroitin-4-sulphate, chondroitin-6-sulphate and aggrecan was positive. However, immunostaining for the typical cartilage specific type II collagen within this zone was negative. The location of the avascular zone corresponds to the region where the tibialis anterior tendon wraps around the superior and inferior retinacula which serve as fibrous pulleys. This is the region where most spontaneous ruptures of the tibialis anterior tendon occur. The presence of fibrocartilage within gliding tendons is a functional adaptation to compressive and shearing forces. In contrast to reports from the literature about the structure of gliding tendons wrapping around a bony pulley, the gliding zone of the tibialis anterior tendon has only a narrow layer of chondroid cells and proof of type II collagen is lacking.
