Sclerosing stromal tumor of the ovary: A case report

Abstract Sclerosing stromal tumor (SST) is an extremely rare and benign ovarian neoplasm of the sex cord stromal category which occurs predominantly in the second and third decades of life. Herein, we report a case of sclerosing stromal tumor of ovary in a 22 year old woman who was clinically suspected to have malignancy, but proven to be SST of ovary on histopathological examination. Hence, in such circumstances it is essential to keep in mind the possibility of sclerosing stromal tumor in a young woman

Percutaneous angio-embolization of a post laparoscopy complex utero-adenexal vascular malformation

Vascular abnormalities are uncommon causes of uterine bleeding. Laparoscopic surgeries, however, require expertise and improper techniques can lead to major vascular complications. We report an unusual case of utero-adenexal arterio- venous fistula with arterio - venous malformation due to pelvic trauma caused during laparoscopic sterilisation procedure, which was treated by percutaneous embolisation technique. To the best of our knowledge, this is the first documentation of such a complex vascular injury caused by laparoscopic sterilisation and its endovascular managemen

Pictorial essay: Orbital tuberculosis

Tuberculosis of the orbit is rare, even in places where tuberculosis is endemic. The disease may involve soft tissue, the lacrimal gland, or the periosteum or bones of the orbital wall. Intracranial extension, in the form of extradural abscess, and infratemporal fossa extension has been described. This pictorial essay illustrates the imaging findings of nine histopathologically confirmed cases of orbital tuberculosis. All these patients responded to antituberculous treatment

Hyperkeratotic pitted plaques on the palms and soles

Lichen planus (LP) and lichen nitidus (LN) present with varied morphology on the palms and soles. We present four unusual cases of palmoplantar LP and LN manifesting as hyperkeratotic plaques with pits. The diagnosis was confirmed histologically. Subtle features like presence of violaceous border suggests LP and plugs within the pits suggest LN

Ormeloxifene-induced unfolded protein response contributes to autophagy-associated apoptosis via disruption of Akt/mTOR and activation of JNK

Abstract Autophagy, a regulated nutrient recycling program can affect both cell survival and cell death. Here, we show that Ormeloxifene (ORM), a selective estrogen receptor modulator approved for oral contraceptive use induces autophagic flux in ovarian cancer cells, which is activated by an ER stress response upstream of autophagy. The ER stress response is characterized by activation of IRE1α, PERK and ATF6 and is under regulation of JNK. Pharmacological inhibition of either autophagy or ER stress increased cell survival, as did silencing of autophagy proteins LC3 and Beclin 1, implying that ORM-induced autophagy is pro-death in nature. Ultrastructural observations of treated cells confirmed stages of autophagic maturation. Caspase-dependent apoptosis succeeded these events and was characterized by generation of reactive oxygen species and disruption of mitochondrial membrane potential. A concomitant inhibition of the Akt/mTOR axis was also observed with possible regulation of Akt by ORM. ORM inhibited tumor growth in ovarian xenograft model and displayed autophagic activity. In summary, in vitro and in vivo results reveal that ORM induces autophagy-associated cell death to attenuate proliferation of ovarian cancer cells. Our results demonstrate that using ORM in combination with ER stress and autophagy modulators could offer better therapeutic outcome in ovarian cancer

Bilhemia after trans-jugular intra-hepatic porto-systemic shunt and its management with biliary decompression

Bilhemia or bile mixing with blood is a rare clinical problem. The clinical presentation is usually transient self-resolving hyperbilirubinemia, progressive and rapidly rising conjugated hyperbilirubinemia, or recurrent cholangitis. Endoscopic retrograde cholangiopancreatography (ERCP) plays an important role in diagnosis and management. Biliary decompression with endoscopic sphincterotomy is useful in treating these patients. If not recognized and treated in time, the condition can be fatal in a significant proportion of patients. This usually occurs after blunt or penetrating hepatic trauma due to a fistulous connection between the biliary radicle and portal or hepatic venous radical. Cases have been described due to iatrogenic trauma such as liver biopsy and percutaneous biliary drainage. However, the occurrence after trans-jugular intra-hepatic porto-systemic shunt (TIPS) is very rare. We report a case of bilhemia presenting as rapidly rising bilirubin after TIPS. The patient was managed successfully with ERCP and removal of a blood clot from the common bile duct
