Rapid Growth of Hydatid Cyst: A Pediatric Case Report.

Iran J Parasitol 2021 Jan-Mar;16(1):164-167

Department of General Surgery, Shiraz University of Medical Sciences, Shiraz, Iran.

Hydatid disease is a parasitic infection caused by with worldwide distribution. The most affected organs are liver and lungs, but it can be detected in any other organs as well. We reported a 5-yr-old boy from Shiraz, southern Iran in 2017 who presented with abdominal discomfort. Imaging revealed multiple liver hydatid cyst and a huge kidney hydatid cyst. This case showed the possible implication of rapid growth of multiple hydatid cyst as well as unusual organ presentation in the pediatric population.

IL-27, a pleiotropic cytokine for fine-tuning the immune response in cancer.

Int Rev Immunol 2020 Nov 4:1-11. Epub 2020 Nov 4.

Interleukin (IL)-27, a member of the IL-6/IL-12 family, has an important role in modulating inflammation in partnership with innate and adaptive immune cells. IL-27 binding to IL-27R starts downstream signaling based on the target cells. It can instigate inflammation by inducing CD4 T cell proliferation, Th1 polarization, cytotoxic T cell activation, generation of the natural killer cell, and macrophage and dendritic cell activation. However, by inducing programmed cell death and suppression of effector cells, IL-27 can suppress inflammation and return the immune response to hemostasis. Altogether, IL-27 displays multifaceted dual functions, which may result in either pro- or anti-inflammatory effects. Recent investigations indicated the antitumor activity of IL-27 via inducing Th1, and CTL responses and generating NK cells. On the other hand, IL-27 also can promote tumor cells' proliferation, survival, and angiogenesis. In the present review, we'll discuss recent advances concerning the role of IL-27 in inflammatory diseases such as infections, autoimmune diseases with a focus on cancer.

Successful Surgical Separation of Thoraco-Omphalopagus Symmetrical Conjoined Twins in Iran: Two Case Reports.

Iran J Med Sci 2020 Mar;45(2):143-147

Student Research Committee, Department of Otorhinolaryngology, Shiraz University of Medical Science, Shiraz, Iran.

Conjoined twins are derived from the division of a single fertilized ovum; a phenomenon accompanied with multiple congenital anomalies. Such twins are identical, of the same sex, and more likely to be female. Most twins die during the embryonic period, and only 18% survive longer than 24 hours. There are complex anomalies in thoraco-omphalopagus twins that makes them unlikely to live long enough to undergo separation. Treatment of this uncommon condition presents both surgical and anesthetic challenges. The management of rare anomalies is difficult even for skilled surgeons. Therefore, it is logical to use the knowledge gained from previous experiences. We herein present the first successful surgical separation of two pairs of thoraco-omphalopagus conjoined twins at the Pediatric Surgery Center of Namazi Hospital (Shiraz, Iran). In both cases, the neonates had separate hearts and common pericardium. Contrast-enhanced computed tomography of two sets of twins showed fusion of sternum, pericardium, diaphragm, and left lobe of liver. Critical steps of the surgical separation were identified and contingency plans were made for possible partial liver donation and cross-circulation between twins. The separation procedure and reconstruction of the abdominal wall were successfully performed. Both pairs of twins, now 6- and 8-year-old, are healthy and have normal growth and are under follow-up.
