Abstract
Introduction: PMA is known to induce the differentiation of monocytes to macrophages. This agent also increases the killing effect of the monocytes/macrophages through oxidative burst and can be used as a stimulant for oxidative burst assay. The present experimental study was intended to investigate the in vitro effects of PMA on the differentiation, morphological changes, cell adherence and the viability of monocyted-derived macrophages (MDMs). Besides, MDM capacity for free radical production was assessed, indicating the oxidative burst events.
Materials and Methods: This experimental study has been design in Department of Immunology of S.B.M.U in Tehran Iran (year 2000). Peripheral mononuclear cells from adult Balb/c mice were isolated and cultured in complete tissue culture medium and divided in two group: control, (without PMA) and test (were added Pma=450 ng/ml). MDMs wee counted on the hours 1, 2, 3, 4, 6 and 18 and their characteristics were confirmed by morphological analysis (histological features) in both groups. Viability of MDMs was assessed using trypan blue. In the peak time of MDMs activation the oxidative burst was determined by NBT reduction.
Results: The obtained results suggested that PMA had significant effect on the differentiation of monocytes to macrophages. The morphologic maturation tended to occur in earlier stages in the PMA treated cells comparing to the control MDMs. Also, the number of adherent cells was considerably more in PMA stimulated monocytes. The peak time of cell adherence in the presence of PMA was no the second hour. As the incubation period increased, the significant difference between the numbers of adherent cells in two culture systems decreased. However, viability decreased significantly in the PMA treated MDMs, i.e. PMA treatment induced rapid apoptosis in the MDMs after their activation. PMA stimulated MDMs markedly (60%). Also we mentioned that the primary un-stimulated MDMs only revealed (55%) of NBT reduction after treatment with PMA at NBT reduction stage.
Conclusion: Phagocytic function and oxidative burst assay in monocyte-macrophage lineage can be a diagnostic tool for identification and management of some Immunological abnormality and defect and can be establish distinct from other phagocytic system assessment.

Abstract
Background: The aim of this study was to evaluate the mechanical and infectious complications of continuous ambulatory peritoneal dialysis catheter in surgical wards of Imam Khomeini Hospital.
Methods: We retrospectively reviewed 80 catheters that were inserted into 69 patients (52 men and 28 women) with end-stage chronic renal failure during a period of 84 months (13 Nov. 1996 to 13 Nov. 2003.
Results: The mean age of patients was 48:35 years (16 to 79 years). The most common complications were infectious ones (71.25%), while the most common causes of the catheter removal were mechanical ones (46.5% vs. 39.55%. The predominate cause of the mechanical complications was improper position (17.5%). Migration of catheter to upper abdomen and outflow failure were the other common mechanical complications. The most common infectious complication was peritonitis (62.5%).
Conclusions: The occurrence of the mechanical complications is lower than the infectious ones, but the probability of catheter loss is higher if it occurs.

Background: Chronic peritoneal dialysis
is a safe method for the treatment of end-stage renal failure. Worldwide,
patients on chronic peritoneal dialysis constititute approximately 15%
of the total number of patients on dialysis. In Iran, very few people have access
to chronic peritoneal dialysis, which is targeted by the Ministry of Health. This
lack of access is primarily due to the high occurrence of mechanical
complications. Improving catheterization procedures is an important way to
extend the use of peritoneal dialysis in Iran. Thus, a prospective study was
implemented to evaluate the outcome of a new laparoscopic technique for the insertion
of peritoneal dialysis catheters under local anesthesia.
Methods: A
total of 115 catheters (two-cuff, swan-necked, coiled) were
inserted into the peritoneal cavity of 109
patients with end-stage chronic renal failure during a 16-month
period. The method of insertion was a two-port laparoscopic technique with
local anesthesia and sedation. All patients were followed for 12
to 28 months. We prospectively evaluated mechanical
and infectious complications and survival rates of the catheters.
Results: The
average age of the patients was 51.5 years (range: 15-84
years) 54.8% of these patients were female. The overall
one-year and two-year catheter survival rates using this approach were 88%
and 73%, respectively. Event-free catheter survival
was 35%. The most common infectious and mechanical
complications were peritonitis in 52
cases (45.2%) and temporary dialysate leakage in 10
cases (8.7%) respectively.
Conclusion: Laparoscopic insertion of
peritoneal dialysis catheter with local anesthesia is a safe and simple
procedure, giving reasonable rates of catheter survival and complications.

Abstract
Background: Leishman Denovani is an obligatory intracellular parasite that is seen such as Leishmanbody or Amustigote in intra reticolo-endothelial system. Leishmanenios is seen as sporadic-endemic or epidemic in many places in the world. In Iran in Fars state and west Azarbayjan is endemic and in other places are in sporadic form and is found in rural areas.
Case report: A four year-old girl was admitted with visceral Leishmaniasis and Subsequently developed peritoneal tuberculosis. The patient who lived in Dashte- Moghan, complained of abdominal pain and distention and weight loss from 1.5 years ago. The titre of IFA test for leishmansis was 1/1280. Leishman body was seen in bone marrow aspiration specimen. Bone marrow culture for leishmania was negative. The specimen of acsities fluid revealed sero- fibrino- purulent exudate with lymphocyic dominancy (over 90%). No response to classic lishmanisis treatment had been started unless the patient treated with anti tuberculoid regimen.
Conclusion: The function of the T-helper (Tht) lymphocytes will decrease in Kala-azar disease. This is why there is no skin reaction to Manteaux (PPD) diagnostic test the patient. The patient have been suffering from long-term malnutrition with its consequent immune defect. There was no evidences of cure in our patient during classic Kala-azar therapy. After she received anti tuberculosis therapy she revealed clinical improvement with Glucantim regimen as well.

Abstract
Background: Vascular complications, as the most common complications of diagnostic catheterization and percutaneous coronary intervention (PCI), are important factors in the morbidity of patients undergoing such procedures thus, this study was done to evaluate the prevalence of these complications and their related factors.
Methods: This is a descriptive study composed of 2097 consecutive patients who underwent percutaneous coronary intervention in Shahid Rajaei Cardiovascular Center in Tehran, Iran from January 2008 to January 2009. Occurrence of vascular complications in course of hospitalization and the related factors leading to the complications were investigated.
Results: Out of 2097 patients, 1544 (73.6%) were male and 553 (26.4%) were female, and the mean age of the participants was 57±10 years. Vascular complications from the time of PCI to the time discharge were observed in 19 (0.9%) patients. The other complications included: hematoma in 10 cases (52.6%), pseudoaneurysm in five cases (26.3%), retroperitoneal hemorrhage and arteriovenous fistula in 2 (10.5%) patients each. The complications were significantly more common in female patients (P=0.003), in patients with a history of hypertension (P=0.02), people of shorter stature (P=0.004), and being on gp IIIa/IIb inhibitors (P=0.003).
Conclusion: The rate of vascular complications post-percutaneous coronary interventions is low and it is considered to be a good treatment option for patients with coronary stenosis provided that sufficient compression is applied on the vascular access point in the right time after removal of the arterial sheath. PCI is of fewer vascular complications, especially in female patients, history of hypertension, and higher anticoagulant concentrations.

Abstract
Background: The aim of this study was to assess the role of consolidative intraperito-neal chemotherapy with carboplatin in decreasing relapse and increasing survival in advanced epithelial ovarian cancers, as well as evaluation of its toxicity.
Methods: In this clinical trial 30 patients with epithelial ovarian cancer in stages II-IV who had complete surgery (optimal debulking surgery) received six standard cycles of intravenous carboplatin and paclitaxel. They were enrolled through non-random se-quential selection. The control patients were similar to case group in stage (II-IV) and pathology (epithelial ovarian cancer). The control group was evaluated retrospectively through hospital files. This clinical trial performed in Gynecology Oncology department in Tehran Valiasr University Hospital, during 2005-2010. They including 18 cases as the intervention group receiving intraperitoneal chemotherapy and 12 patients as the control group with only retrospective follow-up. The cases received 3 cycles of 400 mg/m2 intraperitoneal carboplatin every 21 days following intravenous chemotherapy. Relapse of disease was diagnosed as increasing or even doubling CA125 serum titer during one month, or any CA125 above 100 IU, or an abdominal or pelvic mass in ul-trasound or physical exam. Mean survival of two and five years, progression-free inter-val (PFI), overall survival (OS), relapse, demographic parameters, drug toxicities, path-ologic types of cancers in two groups were coded and compared using SPSS 14. Any P<0.05 was considered as a significant difference.
Results: The mean ages of cases and controls were 52.4±8.6 and 55.1±11.5 years. The mean duration of relapse-free survival was 13±8.6 months for the cases and 9.5±4.3 months for the control patients (not statistically different, P>0.05). The mean overall survival for cases and controls were 39±16.5 and 30.8±16.2 months, respectively (no significant difference, P>0.05). The frequency of drug toxicities in the cases was 5.6%, and consisted of mild-to-moderate abdominal pain, nausea and vomiting.
Conclusion: It seems that consolidation therapy with intraperitoneal carboplatin may not increase overall survival, reduce relapse rate or decrease mortality, though it does not induce considerable side effects. Since the mean survival in the intervention group was nine months more than controls, this difference may be clinically significant.

Abstract
Background: Peritoneal dialysis is one of the most commonly used treatment methods for the patients with end stage renal failure. In recent years, the mortality rate of patients under this treatment has decreased; however, long-term survival is still an important challenge for health systems. The present study aimed to predict the survival of continuous ambulatory peritoneal dialysis patients.
Methods: In this retrospective study, according to the difference of relative importance of demographic characteristics, laboratory data, dialysis adequacy parameters and nutritional status in various patients, the factors affecting the survival of peritoneal dialysis patients have been identified by random forest algorithm. Then, the clinical and laboratory data of patients undergoing continuous ambulatory peritoneal dialysis treatment were evaluated retrospectively from July 1996 to April 2014 in 18 peritoneal dialysis centers, using multi-class one against all support vector machine (OAA-SVM) and multi-space mapped binary tree support vector machine (MBT-SVM) algorithms.
Results: 3097 patients were studied with the mean age of 50.63±15.67 years and average follow-up time of 24.48±19.13 months. The results of the random forest algorithm have identified 35 factors as the most important predictors of peritoneal dialysis patient’s survival. Then, the prediction of peritoneal dialysis patients’ survival status was evaluated using one against all support vector machine and multi-space mapped binary tree support vector machine algorithms in 5 classes of patients including “still on peritoneal dialysis”, “transferred to hemodialysis”, “received a kidney transplant”, “died” and “improved kidney function”. The reliability of survival prediction algorithms were 51.99% and 89.57% respectively.
Conclusion: An accurate prediction model would be a potentially useful way to evaluate patients’ survival at peritoneal dialysis that increased clinical scrutiny and timely intervention could be brought to bear. So, in this research, the multi-space mapped binary tree support vector machine algorithm has a high precision in predicting the survival of continuous ambulatory peritoneal dialysis patients considering multiple evaluation indices and different class distribution functions.

Abstract
Background: Hydatid cyst is an endemic disease in Iran and many middle eastern countries. The clinical presentation of Echinococcus granulosus infection depends upon the site of the cysts and their size. Small and/or calcified cysts may remain asymptomatic indefinitely. However, symptoms due to mass effect within organs, obstruction of blood or lymphatic flow, or complications such as rupture or secondary bacterial infections can result. The most common involved organs with this parasite are the liver and lung. Unusual areas of the disease include breast, adrenal, appendix, peritoneum, omentum and mesenteric. The purpose of this study was to report a rare case of abdominal hydatid cyst with presentation of ovarian cyst in ultrasonography.
Case Presentation: A 26-year-old virgin woman with abdominal pain in the hypogastric region and lower and right quadrant of the abdomen, with gastric fullness and without nausea and vomiting referred to an emergent unit of Ghaem Hospital (an academic hospital of Mashhad University of Medical Sciences) in June 2017. In an ultrasound, a cyst of 95×105 mm in right adnexa of uterus was seen. Due to continued abdominal pain, laparotomy was performed for the patient. At the time of laparotomy, the ovaries, uterus and adnexa were completely normal. A 10×15 cm cyst was seen with a thin wall which adhering to the omentum and the small end of the stomach. Frozen section biopsy reported hydatid cyst.
Conclusion: Considering that hydatid cyst is endemic in Iran, the presence of cystic mass in the peritoneal cavity, hydatid cyst should be considered. To prevent complications and relapse, it is best to avoid cyst rupture during surgery as much as possible.

Abstract
Today surgery is supposed as the cure for many diseases and the fear of post-operation pain burdens stress over the patients. Postoperative pain can, especially if severe, complicate the patient's condition and may lead to chronic postoperative pain. post-operation pain control is effective in the recovery process, hospitalization period and patients’ satisfaction. Insufficient post-operation pain control increases complications and care costs. Local analgesia is one of the components of multimodal postoperative. analgesic protocol to control pain. Local analgesia technique is a simple, accessible and feasible method for various surgeries. The opioid analgesics to control post-operation pain are associated with some complications such as opium addiction, nausea and vomiting, late return of bowel function and social costs. This review study aims. to review previous studies on the effect of injection of analgesic agents in the surgical incision in post-operation pain control. This is a Narrative review study. to related scientific documentaries a search was conducted in Persian and English using the keywords of local injection of the incision site, wound infiltration with analgesic agents and post-operation pain control in Google scholar, PubMed and Scopus database during the years 2000 to 2020. The obtained articles included systematic reviews, Meta-analyses and randomized clinical trials (RCT). We reviewed studies that had utilized single-dose injection of analgesic agents in surgical incisions at the end of surgery to control post-operation pain. A total of ten studies were reviewed. There were 4 studies in the field of laparoscopic gynecological and non-gynecological surgeries, three studies in the field of laparotomy and three review studies. injection of analgesic agents in the surgical incision to control post-operation pain is easily available and does not necessitate any special skill. On the other hand, it is a safe method without further complications and does not increase the duration of surgery. Regardless of the differences in various studies and the kind of analgesic agents, a general reduction in pain severity and consumption of opioid and non-opioid analgesic agents were observed using the injection of analgesic agents in surgical site incision.
