Fetal hepatic calcifications can be caused by infections, chromosomal disorders, thrombotic events, ischemic hepatic necrosis and subcapsular hematomas among others events. Its features and clinical significance are still not well known. We performed an observational study to describe fetal hepatic calcifications and its association with main clinical and histopathological findings from the fetal autopsy database, between 2007 and 2014. Raw odds ratio analysis was performed. We reviewed 591 fetal autopsies: 14 cases with hepatic calcifications, 102 fetuses with chromosomal disorders; 13 with diagnosis of TORSCH (toxoplasma, rubella, syphilis, cytomegalovirus, herpes virus 1 and 2, and others) and 207 with any abnormality in the umbilical cord (UC)...

Mesenchymal stem cells (MSCs) negatively modulate immune properties. Induced pluripotent stem cells (iPSCs)-derived MSCs are alternative source of MSCs. However, the effects of iPSC-MSCs on T cells phenotypes in vivo remain unclear. We established an iPSC-MSC-transplanted host versus graft reaction mouse model using subcapsular kidney injection. Th1, Th2, regulatory T cells (Treg), and Th17 phenotypes and their cytokines were investigated in vivo and in vitro. The role of caspases and the soluble factors involved in the effects of MSCs were examined...

A 50-year-old male patient presented to the neuro-ophthalmology clinic with chief complaints of gradual decrease in vision in both eyes, more in the left eye, for 6 years. On general examination, the patient had a hemiplegic gait. His presenting acuity was 20/50 in the right eye and 20/320 in the left eye, not improving further. He had dense posterior subcapsular cataracts in both eyes, and fundus examination revealed pale discs. Humphrey visual field tests 30-2 revealed a vertical nasal midline defect in the right eye and grossly depressed fields in the left eye...

Background: A rare percutaneous nephrolithotomy (PCNL) complication and its management is reported. Case Presentation: A male patient, 43 years of age, underwent PCNL for a large left pyelocaliceal stone. Surgery was performed in the Valdivia-Galdakao supine position. The percutaneous tract was established by combined radiologic and sonographic guidance. The tract was dilated by balloon and a 24F Amplatz sheath was located. As complete clearance was not achieved because of a residual lower pole caliceal stone, a ureteral Double-J and a 20F nephrostomy were located for a second-look PCNL through the same tract after 7 days...

Liver compartment syndrome is a life-threatening complication of hepatic subcapsular hematoma; diagnosis and assessment of treatment effects are therefore important. We report a rare case of liver compartment syndrome due to spontaneous hepatic subcapsular hematoma without any underlying conditions, in which Doppler ultrasonography (US) proved useful in both diagnosis and assessment of treatment effects. A 32-year-old woman experienced sudden epigastralgia and was diagnosed with hepatic subcapsular hematoma in the right lobe, based on contrast-enhanced computed tomography...

We used multi-row detector computed tomography (MDCT) to identify the distinguishing characteristics of hepatic paragonimiasis and small hepatocellular carcinoma lesions. We analyzed a cohort of 60 patients, of which 26 had hepatic paragonimiasis and 34 with a small (≤ 3cm) hepatocellular carcinoma. MDCT detected 65 lesions that were retrospectively reviewed and analyzed based on their imaging features. Both groups showed distinct MDCT imaging features that could contribute to an accurate diagnosis. In the paragonimiasis group, 75% (21/28) lesions were located in the hepatic subcapsular region, whereas only 10...

There is no consensus regarding which therapeutic option is better and/or safer for treating hemodialysis (HD) patients with hepatocellular carcinoma (HCC). The present study compared surgical resection (Hx) and radiofrequency ablation (RFA) with regard to therapeutic efficacy in HD patients with HCC. Of 108 HD patients with naïve HCC treated at 15 institutions between 1988 and 2014 enrolled in the present study, 58 fulfilled the up-to-7 criteria [7 as the sum of the size of the largest tumor (cm) and the number of tumors] and were treated with Hx (n=23) or RFA (n=35); their clinical features, complications and prognosis were assessed...

The adrenal cortex is characterized by three histologically and functionally distinct zones: the outermost zona glomerulosa (zG), the intermediate zona fasciculata, and the innermost zona reticularis. Important aspects of the physiology and maintenance of the adrenocortical stem/progenitor cells have emerged in the last few years. Studies have shown that the adrenocortical cells descend from a pool of progenitors that are localized in the subcapsular region of the zG. These cells continually undergo a process of centripetal displacement and differentiation, which is orchestrated by several paracrine and endocrine cues, including the pituitary-derived adrenocorticotrophic hormone, and angiotensin II...

Renovascular hypertension (RVH) is a progressive disease, leading to chronic kidney disease when untreated and no specific treatment is available. Therefore, development of new therapeutic modalities is imperative. RVH is triggered by renal artery stenosis and subsequent renin-angiotensin-aldosterone system activation; it can be experimentally induced by the 2 Kidneys-1 Clip (2K1C) model. This study investigates the therapeutic potential of renal subcapsular mesenchymal stem cell (MSC) infusion in 2K1C rats...

Transforming Growth Factor Beta (TGFβ) potently induces lens epithelial to mesenchymal transition (EMT). The resultant mesenchymal cells resemble those found in plaques of human forms of subcapsular cataract. Smad signaling has long been implicated as the sole driving force of TGFβ-mediated activity. Rat lens epithelial explants were used to examine the role of the Smad-independent signaling, namely the MAPK/ERK1/2 signaling pathway, in the initiation and progression of TGFβ-induced EMT. Phase contrast microscopy was used to observe the morphological changes associated with TGFβ-induced EMT in this model, including cell elongation, cell membrane blebbing, cell loss as indicated by the area of bare capsule and capsular wrinkling...

The lymph node (LN) pre-metastatic niche is faintly characterized in lymphophilic human neoplasia, although LN metastasis is considered as the strongest prognostic marker of patient survival. Due to its specific dissemination through a complex bilateral pelvic lymphatic system, early cervical cancer is a relevant candidate for investigating the early nodal metastatic process. In the present study, we analyzed in-depth both the lymphatic vasculature and the immune climate of pre-metastatic sentinel LN (SLN), in 48 cases of FIGO stage IB1 cervical neoplasms...
