Background: Preterm labor is defined as delivery before 37 weeks of gestation. Recurrence of preterm labor in future pregnancies is 6-8%. History of preterm labor is a strong risk factor for future preterm labor. Preterm labor is the leading cause of neonatal mortality in developed countries, but permanent morbidity in these premature neonates has many side effects for the newborn as well as their family members and society. For this reason we conducted a survey to identify risk factors for recurrent preterm delivery among primiparous women with previous preterm delivery.
Methods: This prospective case–control study included patients from three university hospitals, namely Imam Khomeini, Shariati and Mirza Koochakkhan Hospitals, all in Tehran, Iran. Subjects, including 539 primiparous women who delivered preterm (22–36 weeks), were divided into two groups: 47 had a second preterm delivery (study group) and 492 had first preterm delivery (control group). Exclusion criteria were induced preterm delivery due to medical indications in mother and primigravid. Data collection and analysis was performed using SPSS 10 and t-test and χ2 test were used to analyze the significance of the results.
Results: From a total of 6,537 deliveries, we found 539 cases of preterm delivery, among which 47 cases were identified as recurrent preterm delivery. The control group was composed of 492 deliveries. The recurrence of preterm delivery was 8.7%. Uterine anomaly, cardiovascular, renal and thyroid disease in mother and blood group A had a significant correlation with recurrent preterm delivery.
Conclusion: Expectant mothers with uterine anomalies, cardiovascular, renal or thyroid diseases or group A blood type should receive extra care, observation and instructions in order to limit the risk of preterm delivery and its subsequent effects.

Methods: We performed a study with escalating doses of
gemcitabin combined with carboplatin in 21 patients. All patients who were treated in Vali-Asr
hospital between 2003- 2005 evaluated. Gemcitabin with dose of 800mg/m2 was given on days 1, 8 and 15 followed by one week rest period for a 28 day cycle.
Combine with carboplatin with AUC 4 given on day 2. All patients with surgically resected,
histologically confirmed epithelial ovarian cancer and who had failed first-
line platinum chemotherapy were allocated to this study.
Results: Median age was 49 years (range 23-78 years). Median follow-up was six months (range 4-22). Total of 87 cycles of
chemotherapy were administered with median number of four (range 2-6 cycles).
Thrombocytopenia (grade I) and leucopenia (grade I) were seen in 4.75% and 9.52% of patients.
Conclusion: Gemcitabin and carboplatin Combination was tolerated
in patients with recurrence of ovarian cancer.

Background: Langerhans cell histiocytosis (LCH) is a group of idiopathic disorders characterized by the proliferation of specialized bone marrow-derived Langerhans cells and mature eosinophils. The estimated annual incidence ranges from 0.5-2 cases per 100,000 persons per year. The pathogenesis of LCH is unknown. The prevalence of LCH seems to be higher among whites and males. The most common complaints at presentation are those related to bone lesions. Treatment consists of surgery, chemotherapy and radiotherapy alone or in combination. The age of onset varies according to the variety of LCH. Solitary lesions may occur in bones or skin. Cutaneous lesions present with firm, painless papulonodules or vesicles.
Case report: This six-month-old baby presented with firm papulonodules on her temporal skin, but fortunately her other organs were healthy. She underwent two surgeries, separated by a one-month interval. Due to local recurrence after a short period of time, she underwent a 10-Gy dose of radiation. Her response proved good during follow-up.
Conclusion: Radiotherapy is good for controlling local recurrence in LCH, with few sequelae related to treatment.

Background: Breast conservative therapy is associated with
similar outcomes in comparison with mastectomy. The
aim of this study is assessment of local recurrence rate and related risk
factors in patients who have been treated with radiotherapy after conservative
surgery for breast cancer.
Methods: This is a cohort study which data of all breast
cancer patients who have visited in follow up clinic in radiation oncology
department of cancer institute of Imam
Khomeini Hospital
complex in Tehran, Iran,
during years 2007-2009 were collected. All
of the patients were investigated for local recurrence and the possible risk
factors.
Results: Two hundred and seventy seven patients have entered
the study and all have followed for at least one year since data entry. Median
follow-up time from the start of radiotherapy were 35
months (12-148 mo).
We had seven cases (2.5%)
with local recurrences (2.5%)
which most of them occurred in first year after treatment. Because
of low rate of recurrence none of the variables such as margin and nodal status
has significant correlation with local recurrence which this should be due to
small number of patient and short time of follow up.
Conclusions: At
median follow up of 35 months from the beginning
of radiation therapy, local recurrence rate was 2.5% which
is similar to the literature. We recommend to follow a
larger group of patients for longer times to estimate recurrence risk after breast
conservative therapy.

Background: The inguinal hernia is a common disorder in general surgery. Different methods have been described for repair of these hernias. In modern methods, synthetic mesh is used to cover the wall defect and the most known method is Lichtenstein surgical repair. The laparoscopic totally extra peritoneal procedure (TEP) is a newer technique of repairing hernia. The aim of this study is to compare the outcomes of totally extraperitoneal laparoscopic inguinal hernia repair versus Lichtenstein open repair in patients with inguinal hernia. Methods: Among 50 patients, 25 cases underwent Lichtenstein procedure and 25 patients underwent TEP technique for repairing primary unilateral inguinal hernia. Findings during the operation have been recorded and the 12-months follow-up of patients in different views was performed through a questionnaire and then the results were compared. Results: The operation duration, the rate of complications and frequency of recurrence were similar in two groups but the hospital stay, postoperative pain, chronic groin pain and the required time to return to normal activity were significantly lower in patients who underwent the TEP method compared to the patients who underwent the Lichtenstein technique (p<0.001, p<0.001, p=0.012, p<0.001, respectively). Conclusion: The TEP surgical technique can be recognized as a safe method with acceptable results for patients and has significant effects on improvement of patients’ quality of life after hernia repair. Suitable results of this surgical method are achieved when the surgeon goes through the learning curve.

Background: HIV infection reduces the immune system and is the most significant factor in the spread of TB in recent years and one of the causes of death in HIV -seropositive patients. TB is the most commonly diagnosed opportunistic infection and the most frequent direct cause of death among HIV infected patients. The HIV infection can accelerate progression of TB infection to active TB disease. Among patients with active TB, those with HIV co-infection have the greatest risk for relapse. Regardless of increasing rate of TB and HIV in Iran, we decided to s urvey outcome of TB in HIV positive patients who treated with standard regimens in the years 2003-2012.
Methods: This retrospective cohort study was conducted on HIV-positive patients with TB referred to Behavioral Diseases Consultation Center and Infectious Diseases Ward of Imam Khomeini Hospital from 2003 to 2012. Outcome was defined as failure, relapse and mortality. Moreover, the relationship between outcomes and number of CD4, co-trimoxazole and antiretroviral intake, type of TB and AIDS defining illness was studied. Results: This study had 135 patients, 8 (5.9%) were females and 127 (94.1%) were males. The mean age of the patients was 40.14+10.02 and the most way to catch HIV in this study was intravenous drug user. There were 3 (2.22%) cases of failure, 15 ( 11.1%) relapse , and 21 ( 15.8%) deaths. Antiretroviral therapy, AIDS defining illness, type of TB and co-trimoxazole intake did not soley affect relapse. CD4 level was the most effective variables in relapse [ Hazard ratio: 0.392 (0.11-1.4) Relative Risk: 0.809 (0.593-1.103) (P=0.068) ]. However, regard to CI95%, the impact of CD4 on relapse is not significant and antiretroviral intake was the most important and effective variable in increasing their survival. Hazard ratio: 0.137 (0.141-0.45) Relative Risk: 0.686 (0.513-0.918) (P=0.001) Conclusion: Overall, receiving antiretroviral was the most important factor influencing the outcome of patients. |

Background: Colorectal carcinoma is considering as a curable disease. Treatment of recurrent cases is hard and sometimes impossible. Evaluation of the rate and affecting factors of recurrence in each hospital would help to decreasing recurrent cases. The aim of this study is evaluation of the rate, clinical and pathologic features, and outcome of recurrent colorectal carcinoma in a referral teaching hospital in Tehran. Methods: Clinical data of 166 curative resections of colorectal carcinoma who were operated between Mehr 1384 and Mehr 1388 (between 23 September 2005 and 23 September 2009) in Imam Khomeini Hospital and were accessible for follow up was collected. Follow up data was collected prospectively up to Farvardin 1391 (19 April 2012). Forty nine recurrences were happened in this period. We compared recurrent and non-recurrent cases for different variables Results: Average age of the patients was 53.5 years, and 47% of them were female. The median time to the diagnosis of recurrent disease was 12 months (range 1 months to 54 months). There were no significant differences between recurrent and non-recurrent patients about age, sex, sub-site of the tumor and sub-type of primary operation. Rate of overall recurrence, local recurrence and distant metastasis were 29.5%, 15.7% and 12.1% respectively. Local recurrence rate was higher in colon cancer (16.44% vs. 15.05%) but distant metastasis rate was higher in rectal cancer (12.9% vs. 10/96%). Rate of curative re-resection was about 25%. Overall survival of the recurrent patients who underwent surgery was better than who underwent chemo or radiotherapy (66.7% vs. 56.8%). Median survival time of recurrent patients after primary surgery was 28 months, and after diagnosis was 12 months (9.28- 14.72,95% CI). Conclusion: In this study the rate of overall recurrence was 29.5%. Local recurrence rate was higher in colon cancer (16.44% vs. 15.05%) but distant metastasis rate was higher in rectal cancer (12.9% vs. 10/96%).

Background: Sacrococcygel region is the most common site for pilonidal sinus and surgery is the most common treatment for it. Numerous operative techniques have been described for management of this disease but a technique with low recurrence and complication rates is the best treatment option. Karydakis has been introduced as a method with less recurrence rate, but it seems that surgeons debate on complications and it is not a common technique in our country. In this article, we will discuss Karydakis procedure and its results after a prospective follow-up in our patients. Methods: This is a prospective single cohort study on the patients with sacrococcygeal pilonidal disease. Cases evaluated in this study included patients underwent Karydakis procedure for their pilonidal sinus from 23 September 2006 to 22 September 2013. Patients were followed-up prospectively after their discharge within the first week, first month and third month for early complications and then annually for recurrence. The length of follow-up ranged from 3 to 77 months (median 36 months). Results: Of 141 patients, 119 (84.4%) were male and mean operating time was 55.52 (35-120) minutes. Mean time to healing wound with no need to dressing was 15.92 (range: 2-120) days and mean time to return to work was 14.44 (range, 1-35) days. Overall rate of early post-operative complications was 21.3% that most of them treated conservatively. Wound breakdown within the caudal part was the most common complication detected in 12.1% of patients and infection was detected in 5.8%. Hematoma, seroma and complete wound breakdown were seen in one patient each. The mean score of patient's satisfaction after one year was 4.91 out of 5. Recurrence was appeared in 1.42% of patients. Conclusion: Karydakis procedure for sacrococcygeal pilonidal disease is associated with low complications, short healing time and return to work, and reasonable recurrence rate.

Methods: This cross-sectional study was conducted in the Department of Surgery at the Baqiyatallah University Hospital, Tehran, Iran, from April 2017 to September 2017. The study was carried out on 182 postoperative patients. Surgeries were performed in different methods such as; open, closed, semi-closed and limited excision. Diabetics, obese patients and patients with acute pilonidal abscess or prior PD surgery were excluded. All patients were followed for at least three years after surgery. During the follow -up period, patients were assessed for recurrence, satisfaction, complications rate and wound healing time. The outcomes were assessed by case notes analysis and follow-up telephone and postal questionnaires.
Results: In this study forty-four patients were operated via closed Method, 48 patients through open, 48 via semi-closed and 42 one's trough limited excision methods. The highest rate of recurrence was in the open group. There were no cases of recurrence in the closed group. There were also less postoperative hemorrhage and faster wound healing in the closed group. The average satisfaction of all patients was 88.9±8.7. The mean satisfaction rate in the closed group was 95.9±5.3 which was higher than other groups.
Conclusion: The results of this study demonstrated that in the non-recurrent cases of sacral pilonidal sinus, complete Excision and primary repair have fewer complications and shows higher satisfaction rate.

Methods: In this randomized double-blind, placebo-controlled trial, the serum level of pyruvate dehydrogenase (PDH) enzyme in total of 26 patients with DLBCL recurrence in compare with 26 healthy individuals in the Sayed Al-Shohada Hospital, Isfahan University of Medical Sciences in Iran from September 2016 to September 2018, were assessed. The clinical data including age criteria, the Eastern Cooperative Oncology Group (ECOG) score rating, total bilirubin, alanine aminotransferase (ALT), aspartate aminotransferase (AST), prothrombin time and international normalized ratio (PT/INR), CT-scan, serum creatinine, platelet count, the absolute number of neutrophils, and the interval until the last treatment were gathered. After obtaining informed consent, blood samples were taken. and the PDH enzyme was measured in case and control groups.
Results: Fifty-three percent of patients were male and the mean age of participants in case and control groups was 37.2±17.3 and 34.8±8.9, respectively. Subsequently, the PDH levels were measured according to the enzyme protocol. The levels of enzyme in patients with relapse were significantly lower than normal ones (P=0.0003). The PDH serum level was also evaluated by age and sex, which did not show any significant differences (P=0.86).
Conclusion: In patients with relapsing B-cell lymphoma, the pyruvate dehydrogenase (PDH) enzyme serum levels were significantly lower than healthy subjects, but this difference was not related to age and gender. In the case of further studies and comparisons beyond this study, this enzyme could be a good candidate, used as an alternative diagnosis tool, in patients with recurrent lymphoma.

Background: one of the growing diseases in the world that affects patient life quality is Inflammatory bowel disease (IBD), including ulcerative colitis (UC). Many environmental factors, including nutritional deficiencies, may influence the development of the disease. This study aims to evaluate the role of the level of vitamin D in UC recurrence.
Methods: We performed this cross-sectional study at Qom University of Medical Sciences from September 2017 to September 2018 on 50 patients with inactive UC, at least six months after diagnosis, in Shahid Beheshti Hospital in Qom. Patients entered the study sequentially from the target population after describing how to perform the plan and obtaining informed consent. Demographic information, including gender, age, medical history, diseases, and body mass index (BMI), were collected using a checklist. Patients were followed for six months for symptoms and the frequency of disease relapse. During the visits, in terms of adherence to treatment and case of recurrence, the number and severity of recurrence were examined, and the results were recorded in the checklist of each patient. At the end of this period, serum vitamin D level was measured. Data were collected by a checklist and analyzed by independent samples t-test, Chi-square, and variance analysis in SPSS version 18.
| Results: Examining the correlation between vitamin D levels and demographic variables shows that low vitamin D levels are significantly associated with an increase in the frequency of recurrences. However, there was no significant relationship between disease duration, age, and body mass index. Among 50 patients, 23 (%46) were male, and 27 (%54) were female, with a mean age of 35.24±10.07 and a mean duration of disease for 15.14±6.67 months. The mean frequency of relapse was 1.34±1.89. The mean level of serum vitamin D was 22.30±13.45 ng/dl. It was significantly associated with the frequency of relapse with a P<0.001. Conclusion: Vitamin D insufficiency is associated with an increased risk of recurrence in patients with ulcerative colitis. |

Methods: The study was performed as a single-blind clinical trial in patients who were referred to the surgical clinic of Rasoul Akram Hospital (PBUH), with the approval of the supralevator collection. Before surgery, Wexner Score were identified in patients who underwent surgery, and the entire path of fistulas and cavities was identified. Clinical outcomes were monitored one day after surgery for up to two months once a week, then every month until complete recovery, and then six months after surgery. After the operation, the patients were examined for recurrence, until the PRF was absorbed, the dressing of the operation site was performed only with normal saline, and the patients were on a low-residue diet so that they could not excrete as much as possible.
|
Results: 10 people participated in the final analysis. The mean age of patients was 33.20 years (26-46 years). Three patients had a history of perianal abscess surgery, two patients had a history of fistula surgery and 1 patient had a history of Fisher surgery. The mean closing time of the cavity was 14.2 days (10-22 days). Two patients (20%) had a fever and two patients (20%) had a surgical site infection. Bleeding and recurrence were not observed in any of the patients. The mean preoperative Wexner score was 0.80±0.76 Which decreased to 0.68±0.50 postoperatively (P=0.045).
Conclusion: Finally, the findings of the study showed that the use of PRF to repair a complex fistula is a method that can be easily repeated with minimal side effects and can heal wounds caused by fistulas with supralevator collection. This treatment can play an important role in the treatment of complex fistulas that have moderate or extensive involvement with the sphincter, or the occurrence of fistulas with sphincter dysfunction. |

Case Presentation: A 54-year-old female patient presented with a vulvar mass in February 2021. The patient mentioned that the mass had existed for ten years and had increased in size in the last two years. After discussion on the tumor board, she underwent surgery. The pathology of the mass was reported to be aggressive angiomyxoma. The patient was treated with a GNRH agonist after surgery. The patient is currently under follow-up and has not had a recurrence so far (March 2020).
Conclusion: Aggressive angiomyxoma is a rare mesenchymal tumor. It has extensive local invasion and a high recurrence rate, but distant metastasis is rare. Estrogen receptors or Progesterone receptors are commonly positive in aggressive angiomyxoma. The best treatment for aggressive angiomyxoma remains unknown. Extensive local resection of the tumor has been reported as an important therapeutic measure. In cases of mass recurrence, reoperation and hormone therapy have been effective. It is important for gynecologists to consider this tumor as a differential diagnosis when dealing with vulvar masses. |

Methods: In this retrospective cohort study, all patients with Hodgkin's lymphoma who were referred to the Oncology and Hematology Center of Ahvaz Shafa Hospital from March 2000 to February 2010 were included. The survival time was calculated from diagnosis to the first recurrence event date (based on month). To assess the process of the disease, demographic characteristics and disease-related variables (including disease stage, chemotherapy, site of lymph involvement, etc.) were extracted from the records of 387 patients with Hodgkin's lymphoma. To investigate the prognostic factors that affect the recurrence of disease the Cox model and RSF were implemented. Moreover, their performance based on the C-index, IBS, and predictor error rate of the two models were compared Data analysis was implemented by using R4.0.3 software (survival and RandomForestSRC packages).
|
Results: The results of the Cox model showed that LDH (P=0.001) and classical lymphoma classification (P<0.001) were associated with an increased risk of relapse in patients. However, the results of the RSF model showed that the important variables affecting the recurrence of disease were the stage of disease, chemotherapy, classical lymphoma classification, and hemoglobin, respectively. Also, the RSF model showed a higher (c-index=84.9) than the Cox model (c-index=57.6). Furthermore, the RSF model revealed a lower error rate predictor (0.09) and IBS index (0.175) than the Cox model. So, RSF has performed better than the Cox model in determining prognostic factors based on the suitability indicators of the model.
Conclusion: The RSF has high accuracy than the Cox model when there is a high number of predictors and there is collinearity. It can also identify the important variables that affect the patient's survival. |

Methods: This retrospective study evaluated the medical records of 500 breast cancer patients at two hospitals in Mashhad, Iran during April 2006 to March 2016. We used SPSS software, version 16 (SPSS Inc., Chicago, IL, USA) to analyze data. A P value less than 0.05 means that the results are considered statistically significant.
|
Results: We included 230 women with breast cancer. The average overall survival was 130.7 months, with 83.2% of people surviving for five years and 78.8% surviving for 10 years. The stage of the disease is strongly linked to the recurrence (P=0.000). Additionally, the specific type of disease is also strongly related to disease recurrence (P=0.01) or metastasis (P=0.01). Patients who have the triple-negative subtype had the highest chance of the cancer spreading and recurrence compared to patients with other subtypes.
Conclusion: The different types of breast cancer are strongly linked to the disease recurrence or metastasis. Patients with triple-negative subtypes had the most cases of cancer spreading to other parts of the body and coming back again, compared to other subtypes. Our findings also showed that patients with the triple-negative disease had the worst overall and disease-free survivals. |
