Subcapsular splenic hematoma is a rare complication of pancreatitis. The management for subcapsular splenic hematoma remains controversial. We herein report a case of a large subcapsular splenic hematoma with a large pancreatic pseudocyst, which was successfully treated with splenic arterial embolization and ultrasound- (US-) guided percutaneous drainage of pancreatic pseudocyst, for the first time. A 44-year-old male suffered from recurrent abdominal pain for more than two years. He had previous 3 episodes of pancreatitis...

Murid Herpesvirus-4 (MuHV-4) is a B cell-tropic gamma-herpesvirus that can be studied in vivo Despite viral evasion, type 1 interferons (IFN-I) limit its spread. After MuHV-4 inoculation into footpads, IFN-I protect lymph node subcapsular sinus macrophages (SSM) against productive infection; after peritoneal inoculation, they protect splenic marginal zone macrophages; and they limit MuHV-4 replication in the lungs. While invasive infections can test specific aspects of host colonization, it is important also to understand natural infection...

Angiomyomatous hamartoma of lymph nodes (AMH-LN) is an uncommon benign proliferation of smooth muscle, blood vessels, collagenous stroma and adipocytes, most commonly affecting inguinal LN. A similar constellation of cell types constitutes various members of the perivascular epithelioid cell tumor (PEComa) family, including lymphangioleiomyomatosis (LAM) which can involve LN in women. Because some LN-LAM patients have tuberous sclerosis complex (TSC) and/or other PEComa family lesions, it is clinically relevant to distinguish LN-LAM from AMH-LN...

Power Doppler sonography (PD) can accurately depict tissue perfusion, recognize slow flows, and is relatively angle independent. The monitoring of local blood flow by Doppler ultrasonography is helpful in differentiating prostatic physio-pathological conditions, but the recognizing of physiological variables that could affect it is crucial to apply this technique in clinical practice. This study aimed to evaluate if ejaculation affects blood flow to the prostate and to state how long this effect lasts. Serial PD examinations of prostate were performed in 18 dogs (1-5 years, 6-40 kg) immediately before (T0) and after (T1) the ejaculation, and repeated 6 (T2), 18 (T3) and 24 (T4) hours later...

BACKGROUND: Advances in cancer therapeutics depend on reliable in vivo model systems. To develop biologically relevant xenografts, ultrasound was utilized for tissue-directed implantation of neuroblastoma (NB) cell line and patient-derived tumors in the adrenal gland, and for renal subcapsular engraftment of Ewing's sarcoma (ES). MATERIALS AND METHODS: NB xenografts were established by direct adrenal injection of luciferase-transfected NB cell lines (IMR32, SH-SY5Y, SK-N-BE2) or NB patient-derived tumor cells (UMNBL001, UMNBL002)...

BACKGROUND: Traditionally, open hepatic resection is the first choice of treatment for symptomatic enlarging hepatic hemangiomas, which requires a large abdominal incision and is associated with substantial recovery time and morbidity. Minimally invasive laparoscopic resection has been used recently in liver surgery for treating selected hepatic hemangiomas. However, laparoscopic liver surgery poses the significant technical challenges and high rate of conversion. Radiofrequency (RF) ablation has been proved feasible in the treatment of hepatic hemangiomas with a size range of 5...

The assessment of sentinel lymph nodes (SLN) on hematoxylin and eosin (H&E)-stained sections in cases of classic type of invasive lobular carcinoma (cILC) is considered unreliable, particularly in cases with minimal involvement, that is by either isolated tumor cells (pN0i+) or micrometastases (pN1mi). Although the impact of minimal SLN involvement has been shown to be insignificant in most clinical trials (even though cILC was either under-represented or not separated in the respective cohorts), the results of MIRROR trial did emphasize the need for additional therapy in cases with minimally involved SLN to ensure improved disease-free survival...

The amniotic fluid is a clinically accessible source of mesenchymal stem cells (AF-MSC) during gestation, which enables autologous cellular therapy for perinatal disorders. The origin of AF-MSC remains elusive: renal and neuronal progenitors have been isolated from the AF-MSC pool, yet no cells with pulmonary characteristics. We analyzed gene expression of pulmonary and renal markers of 212 clonal lines of AF-MSC isolated from amniocentesis samples. AF-MSC were cultured on dishes coated with extracellular matrix (ECM) proteins from decellularized fetal rabbit lungs...

Page kidney is a rarely seen phenomenon leading to secondary hypertension and encountered most frequently due to traumatic or nontraumatic subcapsular hematoma. Such a compression in kidneys causes hypoperfusion and microangiopathic ischemia and activates renin-angiotensin-aldosterone system leading to hypertension. In this presentation, we report a rare case of bilateral Page kidney presenting with hypertension attacks due to spontaneous subcapsular hematoma developing in different kidneys at different times...

This study reports a case of spontaneous subcapsular splenic ruptured hematoma (with hemoperitoneum) and provides update on this rare disease. Non-traumatic ruptures can be fatal. Diagnosis is sometimes difficult. They often reveal an underlying pathology including infections, tumors or hematologic disorders. Symptomatology commonly has an abrupt onset but progressive forms are also possible. The majority of patients undergo splenectomy.

A 75-year-old man with a history of chronic kidney disease (CKD) visited our emergency room after the sudden onset of severe right lower abdominal pain and nausea. Computed tomography (CT) showed right perirenal hematoma and renal tumor, which was diagnosed as a spontaneous rupture of the right renal tumor. It was difficult to correctly diagnose the tumor as benign or malignant with magnetic resonance imaging (MRI). Because of CKD, a shunt was implanted, and dynamic enhanced CT was performed. Dynamic enhanced CT showed a slightly enhanced area of the tumor, and it was diagnosed as renal cell carcinoma (RCC)...

REVIEW
Daisy Y Shu, Frank J Lovicu
Wound healing is one of the most complex biological processes to occur in life. Repair of tissue following injury involves dynamic interactions between multiple cell types, growth factors, inflammatory mediators and components of the extracellular matrix (ECM). Aberrant and uncontrolled wound healing leads to a non-functional mass of fibrotic tissue. In the eye, fibrotic disease disrupts the normally transparent ocular tissues resulting in irreversible loss of vision. A common feature in fibrotic eye disease is the transdifferentiation of cells into myofibroblasts that can occur through a process known as epithelial-mesenchymal transition (EMT)...

Subcapsular bilomas are a rare complication of laparoscopic cholecystectomy and an even more rare occurrence to occur spontaneously. We present a case of left sided subcapsular biloma following a laparoscopic cholecystectomy. The location of the biloma was unrelated to our area of dissection. The operation was without difficult dissection or pressurization of the biliary tree. In addition, we present percutaneous drainage alone, without ERCP as adequate management in subcapsular bilomas.
