Background: Peritoneal washing cytology (PWC) that shows the microscopic intra-peritoneal spread of gynaecologic cancers is not used in staging but is known as prognostic factor and effective in planning the intensity of the therapy. False negative or false positive results clearly affect the ability to make the best decision for therapy. In this study we assessed levels of tumour markers, carcinoembryonic antigen (CEA), cancer antigen 125 (CA-125) and carbohydrate antigen (CA19-9), in peritoneal washing fluid to establish any possible contribution to the peritoneal washing cytology in patients operated for gynaecologic cancer. Materials and Methods: Preoperative tumour markers were studied in serum of blood samples obtained from the patients for preoperative evaluation of a gynaecologic operation. In the same group peritoneal tumour markers were studied in the washing fluid obtained for intraoperative cytological evaluation. Results: This study included a total of 94 patients, 62 with malignant and 32 with benign histopathology. The sensitivity of the cytological examination was found to be 21% with a specificity of 100%. When evaluated with CEA the sensitivity of the cytological examination has increased to 37%. Conclusions: In addition to examination of PWC, the level of CEA, a tumour marker, in peritoneal washing fluid can make a diagnostic contribution. Determining the level of CEA in peritoneal washing fluid will be useful in the management of gynaecologic cancers.

Intraperitoneal administration of radioisotopes is suggested to treat the metastatic ovarian cancer in the peritoneal cavity. Administering beta-emitting radioisotopes into the peritoneal cavity allows the maximum energy delivery to the cancerous cells of the peritoneal wall surface while sparing the normal cells located in deep site of the peritoneal wall. In this study, dose estimates of the peritoneal wall are provided to be used for prescribing the amount of $^{166}Ho$-chitosan complex administered. The $^{166}Ho$-chitosan complex diffused in the peritoneal fluid may attach to the peritoneal wall surface. The attachment fraction of $^{166}Ho$-chitosan complex to the peritoneal wall surface is obtained by simulating the ascites with Fischer rats. Both volume source in the peritoneal fluid and the surface source over the peritoneal wall surface are counted for the contribution to the peritoneal wall dose. The Monte Carlo code EGS4 is used to simulate the energy transfer of the beta particles emitted from $^{166}Ho$. A plane geometrical model of semi-infinite volume describes the peritoneal cavity and the peritoneal wall. A semi-infinite plane of $10{\mu}m$ in thickness at every 1 mm of depth in the peritoneal wall is taken as the target in dose estimation. Greater than 98 percents of attachment fraction has been observed from the experiments with Fischer rats. Given $1.3{\mu}Ci/cm^2$ and $2.4{\mu}Ci/ml$ of uniform activity density, absorbed dose is 123 Gy, 8.59 Gy, 3.00 Gy, 1.03 Gy, and .327 Gy at 0 mm, 1 mm, 2 mm, 3 mm, and 4 mm in depth to the peritoneal wall, respectively.

Background: Intraperitoneal spread of gynecologic cancers is a major cause of mortality and morbidity and often presents with malignant ascites. Microscopic tumor spread can be demonstrated by a peritoneal wash cytology and help assess the prognosis of the disease. In our study, the roles of paraoxonase and ceruloplasmin, measured in peritoneal washing fluid of patients operated for gynecologic pathologies in differential diagnosis was investigated. Materials and Methods: Patients operated for malign or benign gynecologic pathologies in Antalya Education and Research Hospital Gynecology Clinic between 2010-2012 were included in the study. Samples were obtained during surgery. Results: A statistically significant difference was detected between patients with benign and malign diseases with regards to PON1 levels measured in peritoneal washing fluid (p:0.044), the average values being $64.2{\pm}30.8$ (Range 10.8-187.2) and $41.4{\pm}21.4$ (Range 10.4-95.5), respectively. No significant variation was evident for ceruloplasmin. Conclusions: Paraoxonase levels measured in peritoneal washing fluid may contribute to the differentiation of malign-benign diseases in gynecologic pathologies.

Purpose: Consensus is lacking regarding the optimal antibiotic treatment for pediatric complicated appendicitis. This study determined the optimal first-line antibiotic treatment for pediatric patients with complicated appendicitis based on peritoneal fluid cultures. Methods: This retrospective study examined the cases of pediatric patients who underwent appendectomy for complicated appendicitis at our institution between 2013 and 2019. Peritoneal fluid specimens obtained during appendectomy were cultured for the presence of bacteria. Results: Eighty-six pediatric patients were diagnosed with complicated appendicitis. Of them, bacteria were identified in 54 peritoneal fluid samples. The major identified bacteria were Escherichia coli (n=36 [66.7%]), Bacteroides fragilis (n=28 [51.9%]), α-Streptococcus (n=25 [46.3%]), Pseudomonas aeruginosa (n=10 [18.5%]), Enterococcus avium (n=9 [16.7%]), γ-Streptococcus (n=9 [16.7%]), and Klebsiella oxytoca (n=6 [11.1%]). An antibiotic susceptibility analysis showed E. coli was inhibited by sulbactam/ampicillin in 43.8% of cases versus cefmetazole in 100% of cases. Tazobactam/piperacillin and meropenem inhibited the growth of 96.9-100% of the major identified bacteria. E. coli (100% vs. 84.6%) and P. aeruginosa (100% vs. 80.0%) were more susceptible to amikacin than gentamicin. Conclusion: Tazobactam/piperacillin or meropenem is a reasonable first-line antibiotic treatment for pediatric complicated appendicitis. In the case of aminoglycoside use, amikacin is recommended.

Objective: The presence of the various cytokines in human peritoneal fluid has been evaluated incompletely. Changes in cytokine levels may be related to activation of peritoneal macrophage and T-lymphocyte, development of endometriosis, and infertility. This study assesses peritoneal fluid levels of interleukin-6 (IL-6), interleukin-8 (IL-8), interleukin-10 (IL-10) and tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) in infertile women with endometriosis and normal women without endometriosis. Design: Prospective and case-control study in university hospital. Materials and Methods: Cytokine levels in peritoneal fluid obtained during laparotomy or laparoscopy from 21 patients in infertile patients with endometriosis and 24 controls undergoing laparotomy or laparoscopy with no evidence of pelvic endometriosis were determined by enzyme-linked immunosorbent assay. Results: The mean levels of interleukin-6 in infertile patients with endometriosis and controls were $72.7{\pm}23.7$ pg/ml and $18.5{\pm}9.7$ pg/ml respectively (p=0.02). Similarly, the mean levels of interleukin-8 in infertile patients with endometriosis was significantly higher than that of controls ($445.0{\pm}89.6$, vs $45.1{\pm}48.4$, p=0.04). The mean concentration of interleukin-10 in infertile patients with endometriosis was significantly lower than that of controls ($1.09{\pm}0.04$ vs $2.19{\pm}0.03$, p=0.03). The level of tumor necrosis factor-${\alpha}$ was not significantly different between the two study groups. Conclusions: Increased IL-6 and IL-8 and decreased IL-10 levels in the peritoneal fluid may be related to pathogenesis in the endometriosis and infertility, suggesting that partially contribute to the disturbed immune regulation observed in infertili women with endometriosis.

A 47-year-old man with end-stage renal disease due to diabetic nephropathy underwent a peritoneal scintigraphy to evaluate the cause of recently developed scrotal swelling. Two liters of dialysate mixed with 111 MBq of Tc-99m sulfur colloid were administered into the peritoneal cavity via the dialysis catheter. Various anterior images of the abdomen and pelvis were obtained at 15 min, 2 hr and 4 hr after the tracer instillation. At 15 min, anterior images of the abdomen and pelvis demonstrated linear tracts of activity through both inguinal canals, which were more prominent in the right side (A). Images at 2 hr revealed a passage of the radioactive fluid into the right hemiscrotum. At the same time, there was a considerable accumulation of activity in the right inguinal canal (B). In the delayed image, there was a progressive accumulation of activity in the inguinal canals and a prominent passage of the tracer into the scrotum (C). Both abdominal and inguinal hernias are commonly associated with continuous ambulatory peritoneal dialysis (CAPD). Overall incidence of CAPD-induced hernia ranges from 2.7% to 25%.$^{1)}$ Inguinal hernias were frequently manifested as scrotal swelling. Leakages of dialysate fluid into the scrotum has been noted in CAPD patients with scrotal swelling, with or without clinical findings of inguinal hernia.$^{1,2)}$ In the present case, the right side had leakage from a clinical inguinal hernia and the left side, leakage from a subclinial inguinal hernia. A subclinical inguinal hernia was easily demonstrable with peritoneal scintigraphy. Peritoneal scintigraphy is extremely helpful in the evaluation of scrotal swelling in a patient on CAPD.

We evaluated the availability of toluidine blue stain in body fluids, such as peritoneal and pleural fluid and urine. Nine hundreds specimens, i.e., 400 pleural and 400 peritoneal fluids and 100 urine samples, respectively, from Jan. 1995 to May 1996 were included. We obtained the result of high sensitivity and high specificity. In toluidine blue stained body fluid in comparison with Papanicolaou stained result. Additionally, we found the diagnostically important crystals in chylothorax and some urine samples, which can not be seen in routine Papanicolaou stain. We thought the toluidine blue stain in body fluid is one of very useful diagnostic methods.

The entry of antipyrine and urea from the peritoneal cavity of rabbit into organ tissue and blood plasma was studied. Two hundred mg of antipyrine plus 300 mg of urea in 10 ml Ringer's solution was injected into the peritoneal cavity of anesthetized rabbit. The injection was made from above of a rabbit kept tying right side down and it enabled part of the abdominal organs (liver, intestine, kidney) was immersed in the injected solution and kept high concentration gradient throughout the experimental period. The remaining part of the organs was revered only by a thin film of the test solution. Subsequently, in this part of the organs the concentration gradient of the diffusible substances during entry was presumed to decrease as time elapsed. Four pieces of the liver tissue were taken namely, the right superficial, right deep, left superficial and left deep portions. Two were taken from the small intestine, one from the portion which was immersed in. the fluid and the other from that above the fluid mass. Both kidneys were separately analyzed. As a remote organ the gastrocnemius muscle was taken from the right leg of the animal. The intervals which were the time periods elapsed after injections were 5,7,10,15 or 30 minutes. At each point 5 animals were sacrificed and the concentrations of the test substances in the tissue water were measured. The results obtained were as follows. 1. In the liver the right portion which was immersed in the fluid showed higher concentration if the test substances than the left portion and the superficial region exceeded the deep region. The concentrations diminished as the time elapsed after infusion, particulary in the case of antipyrine, suggesting circulatory removal of the substances. In urea such decreasing tendency of the concentration was not obvious, and suggested slower removal rate of it as compared with that of antipyrine. 2. In the small intestine there was no regional difference in the concentration of the test substances. Because of the intestinal motility different portions of the intestine were seemed to have bathed in the fluid of the same concentration. In general the concentrations in the intestinal wall exceeded those of the liver, suggesting a slower removal rate than in the latter. 3. In the kidney the accumulation of the endogenous urea was predominant, and the accumulating mechanism in the renal tissue went on during the period of the experiment. Therefore it revealed increasing tendencies as the time elapsed. The penetration of the test substances in this organ from the peritoneal cavity seemed to be slower than in other abdominal organs, namely liver or small intestine. Part of the test substances in the kidney were obviously brought by the blood stream. 4. Rapid exponential decay of the concentration of antipyrine and of the osmolality of the peritoneal fluid was attributed to the extensive removal through the whole dimension of the peritoneal surface, and the remote organ such as the gastrocnemius muscle attained a fairly close value to that of the abdominal organs in less than 30 minutes. The factors which related to the absorption rate were discussed. They were the concentration gradient, permeability and the regional perfusion rate.

We have previously demonstrated that specific antigens involved in autoimmunity in endometriosis may be endometrial proteins with molecular weight (mw) of 71, 92, and 103 kilodalton (kDa). The purposes of this study were to determine the incidence of IgG antibodies against these endometrial antigens in peritoneal fluid of patients with endometriosis and to evaluate the antigenic differences between the endometria of patients with and without endometriosis. Forty peritoneal fluid (PF) from 24 patients with endometriosis and 16 patients without endometriosis (control patients) were tested against endometrial protein from patients (n=8) with endometriosis and from control patients (n=10) by western blot. Fifteen (62.5%) of 24 PF samples from patients with endometriosis had specific Immunoglobuiin (Ig) G antibodies against one of three endometrial proteins with mw of 71, 92 and 103 kDa but none of PF samples from control patients had these antibodies. The electrophoretic pattern of endometrial proteins from patients with endometriosis was similiar to that from control patients. Furthemore there was no significant difference in specific PF Immunoglobulin G binding to endometrial proteins regardless of origin of these proteins. Our data indicate that specific humoral immune response can be found in PF of patients with endometriosis and that specific antigens inducing this immune response are present in human endometrium and that there is no antigenic difference between the endometria of patients with and without endometriosis.
