A Case of Left-Sided Acute Appendicitis in a 45-Year-Old Man with Situs Inversus Totalis Managed by Emergent Laparoscopic Appendectomy.

BACKGROUND Situs inversus totalis (SIT) is a rare congenital abnormality that includes mirror-image transposition of both the abdominal and the thoracic organs. It may remain undetected into adulthood until an acute medical emergency results in diagnostic imaging. This report presents a challenging case of left-sided acute appendicitis in a 45-year-old man with SIT.

HAART toxicity masquerading as a surgical abdomen.

Introduction: Intussusception is a rare disease in adults and poses a challenge to identify and manage. In adults, surgical resection is the preferred treatment since half are due to malignancy. This case reveals an association between highly active antiretroviral therapy (HAART) and intussusception.

Ex vivo therapy of malignant melanomas transplanted into organotypic brain slice cultures using inhibitors of histone deacetylases.

Disease progression in patients suffering from malignant melanomas is often determined by metastatic spreading into brain parenchyma. Systemic chemotherapy regimens are, therefore, mandatory for successful treatment. Most recently, inhibitors of histone deacetylases (HDACi) have been shown to significantly inhibit melanoma progression.

Variants of bcl-2 specific siRNA for silencing antiapoptotic bcl-2 in pancreatic cancer.

Background And Aims: Pancreatic cancer remains a devastating diagnosis with only limited therapeutic options. Specific inhibition of expression of target genes has become possible using small interfering (si) RNAs. We therefore investigated how far siRNA specific for bcl-2 may serve as a therapeutic option for pancreatic cancer in vitro and in vivo.
