Vaginismus is a sexual disorder that can cause painful intercourse. Although several studies have shown a relationship between higher education and socio-economic level of women with vaginismus, the relationship between demographic characteristics and other variables remains unclear.. The present study was conducted to determine the demographic characteristics of women with vaginismus, coming to family health clinic, between 2007 and 2013..Patients and This study is a cross-sectional study that was conducted on 115 clinical records, from early 2007 until the end of 2013, that have received a diagnosis of vaginismus. In these clinical records, the data on female and male age, education and employment, duration of marriage, type of marriage (traditional, virtual, etc.), being a virgin, erectile dysfunction of husband, information of families, sexual satisfaction, marital satisfaction, residential, non-medical types of medical treatment and hymenectomy were derived.. The results showed that the average age of women was 29 ± 5 years and the average age of the spouses was 33 ± 6 years. Undergraduate education most prominent among women (52%) and spouses (42%). In terms of employment status, most women were housewives (54%) and the majority of male were employees (54%). The most frequent form of marriage was traditional (80%). The maximum elapsed time of marriage was between 1 - 3 years (43%). In most women, the first attempt for intercourse was from the second day of marriage to the end of the first week (73%). Hymenectomy was done by 9% of women. Totally, 45% of the men, the wives of whom were suffering from vaginismus, experienced erectile dysfunction. In 37% of couples, their sexual life was satisfactory. The most referred specialist for treatment was the urologist (17%). In 27% of women with vaginismus, numerous references to a variety of medical specialists and psychologists were also recorded. Of the total, 7% of couples experienced traditional and non-academic treatments.. As vaginismus can affect the stability of marriage, it is necessary to assess sexual dysfunction from all directions, including demographic characteristics and variables that affect the incidence of vaginismus. Therefore, based on the data obtained, we can diagnose and properly treat sexual dysfunction, in time, and teach couples how to deal with it..

Postoperative analgesic effects of ropivacaine have been demonstrated in various surgical procedures; however, its beneficial effect on postoperative pain relief and ability to breathe out air in urological surgeries, particularly in local interventions such as percutaneous nephrolithotomy (PCNL), has remained uncertain.. The aim of this study was to assess the efficacy of ropivacaine on postoperative pain severity and peak expiratory flow (PEF) in patients undergoing PCNL procedure..Patients and This randomized double-blinded clinical trial was performed on 55 consecutive adult patients aged 15 to 60 years who underwent Tubeless PCNL surgery. The patients were randomly assigned to instill 30 mL of ropivacaine 0.2% or 30 mL of isotonic saline with the same protocol. The parameters of visual analogue scale (VAS) (for assessment of pain severity) and PEF (for assessment of ability to breathe out air) were measured 4 and 6 hours after completing the procedure. Moreover, the amounts of opioids or analgesics administered within 6 hours after the operation were recorded.. We found no difference in the mean pain severity score between the case and control groups 4 hours (P = 0.332) and 6 hours (P = 0.830) after the operation. The mean PEF at baseline was similar in case and control groups (P = 0.738). Moreover, no difference was revealed in PEF index 4 hours (P = 0.398) and 6 hours (P = 0.335) after PCNL between the groups. The mean VAS scores 4 hours after the operation slightly decreased 2 hours later (P < 0.001) in the both groups. Moreover, in the both groups, a sudden decrease in PEF index was observed within 4 hours after the operation and increased with a mild gradient for the next 2 hours. No difference was found in the amount of postoperative analgesic used in the both groups.. Instillation of ropivacaine 0.2% (30 mL) within tubeless PCNL surgery does not have a significant effect on postoperative pain relief and improvement of PEF within 6 hours after the operation..

Protein-energy wasting (PEW) and heightened inflammation are prevalent in patients undergoing continuous ambulatory peritoneal dialysis (CAPD) and is a strong risk factor for morbidity and mortality in these patients. Evaluation of PEW, prevalence of inflammation as well as interrelationship between various nutritional indices and inflammation has not been studied in much detail in patients undergoing CAPD.. This study was conducted to evaluate the interrelationship between PEW and inflammation in patients undergoing CAPD..Patients and Sixty-three patients undergoing CAPD (M = 28, F = 35) were assessed with regard to their nutritional status and inflammation after a minimum of 3 months CAPD initiation. Nutritional status was assessed by dietary diary, anthropometry, subjective global assessment, and multifrequency bioelectrical impedance analysis (BIA). In addition, their serum albumin, prealbumin, transferrin, and cholesterol level were measured. Also, inflammation in these patients was assessed by High-Sensitivity C-Reactive Protein (hs-CRP > 3 mg/L) and Interleukin-6 (IL-6 > 2 µg/mL). Later on, diagnosis of malnutrition was made based on different methods. Correlation between inflammation and various nutritional assessment indices were analyzed statistically.. Mean (SD) age of the patients was 57.6 (11.6) years. The average (SD) calorie and protein intake per day were 25.5 (4.6) kcal and 0.81 (0.2) mg, respectively. The mean and standard deviation of anthropometry variables of body mass index (BMI), mid-arm circumference (MAC), tricipital skin-fold thickness (TST), mid-arm muscle circumference (MAMC), and corrected mid-arm muscle area (cMAMA) were 23.7 ± 5 kg/m2, 26.3 ± 4.5 cm, 1.624 ± 0.4 cm, 25.6 ± 4.5 cm, and 45.7 ± 19.7 cm2, respectively. The mean values of serum protein, albumin, prealbumin, transferrin, cholesterol, triglyceride, hs-CRP, and IL-6 were 5.9 g/dL, 3.0 g/dL, 21.11 mg/dL, 130.6 mg/dL, 155.9 mg/dL, 136.1 mg/dL, 8.8 ± 7.6 mg/L, and 8.4 ± 12.2 µg/dL, respectively. Based on subjective global assessment (SGA); 11.63 (17.4%), 34.63 (54%), and 18.65 (28.6%) patients undergoing CAPD had normal, moderate, and severe malnutrition status, respectively. According to serum albumin level; 13.63 (21%), 39.63 (62%), and 11.63 (17%) patients undergoing CAPD had normal, moderate, and severe malnutrition status, respectively. Finally, based on BMI; 33.63 (52%), 23.63 (37%), and 7.63 (11%) patients undergoing CAPD had normal, moderate, and severe malnutrition status, respectively. About 76.1% and 9.5% of patients undergoing CAPD were malnourished based on lean tissue index (LTI) and fat tissue index (FTI), respectively. Based on hs-CRP and IL-6 findings, 70% (44/63) and 71.8% (45/63) of patients undergoing CAPD had high inflammation, respectively. High sensitive C-reactive protein correlated negatively (significantly) with serum albumin, prealbumin, and transferrin. Interleukin -6 correlated negatively (significantly) with MAC; MAMA; serum albumin, cholesterol, and transferrin. There was significant positive correlation between hs-CRP and IL-6. There is statistically significant difference in total protein intake (g/d), protein intake (g/kg/d), serum protein (g/dL), albumin (g/dL), transferrin (mg/dL), and cholesterol (mg/dL) between patients with and without inflammation.. Protein-energy wasting (80% - 85%) by various methods and inflammation (70%) was very prevalent among patients undergoing CAPD. Inflammatory markers show significant negative correlation with anthropometry and serological markers. Inflammatory markers are suggested to be included in the regular assessment of patients undergoing CAPD, for the better management of protein-energy wasting..

Ischemia-reperfusion (IR) injury is one of the most common causes of renal dysfunction. There is increasing evidence about the role of the reactive oxygen species (ROS) in these injuries and endogenous antioxidants seem to have an important role in decreasing the renal tissue injury.. The aim of this study was to compare the effect of recombinant human erythropoietin (EPO) and ischemic preconditioning (IPC) on renal IR injury.. Twenty four male Wistar rats were allocated into four experimental groups: sham-operated, IR, EPO + IR, and IPC + IR. Rats were underwent 50 minutes bilateral ischemia followed by 24 hours reperfusion. Erythropoietin (5000 IU/kg, i.p) was administered 30 minutes before onset of ischemia. Ischemic preconditioning was performed by three cycles of 3 minutes ischemia followed by 3 minutes reperfusion. Plasma concentrations of urea and creatinine were measured. Kidney samples were taken for reactive oxidative species (ROS) measurement including superoxide dismutase (SOD) activity, glutathione (GSH) contents, and malondialdehyde (MDA) levels.. Compared to the sham group, IR led to renal dysfunction as evidenced by significantly higher plasma urea and creatinine. Treatment with EPO or IPC decreased urea, creatinine, and renal MDA levels and increased SOD activity and GSH contents in the kidney.. Pretreatment with EPO and application of IPC significantly ameliorated the renal injury induced by bilateral renal IR. However, both treatments attenuated renal dysfunction and oxidative stress in kidney tissues. There were no significant differences between pretreatment with EPO or application of IPC..

Some studies reported an association between low levels of vitamin D and the risk of infections, especially viral infections. Kidney transplant patients are at risk of opportunistic infections; however, no study has been conducted on the association between vitamin D levels and the risk of CMV infection.. The aim of this study was to compare the level of vitamin D in two groups of patients with and without CMV infection within four months after the transplantation. Moreover, we aimed to find a relation between vitamin D level, before and after transplantation in each group..Patients and Methods;: This prospective cohort study was conducted in Baqiyatallah hospital in Tehran in 2013. A total of 82 kidney transplant patients were enrolled and vitamin D levels were measured in them before transplantation. The kidney transplant patients had been followed up for four months and monitored for the presence of cytomegalovirus antigen (CMV Ag) in their blood. In patients with positive CMV Ag, vitamin D level was measured again when they became positive but in other patients it was measured at the end of follow-up; at the end, characteristics of patients and vitamin D levels were compared between the two groups.. Of all, 40 patients were CMV Ag positive and 42 patients were negative. In most patients transplanted organs were taken from cadaver (66%) and the most common type of dialysis was hemodialysis (92%). Most participants did not undergo antithymocyte globulin therapy (69%) and pulse corticosteroid therapy (83%). Vitamin D level before transplantation was 17.2 ± 11.6 ng/mL. In patients with positive results or at the end of follow-up in patients without CMV Ag, vitamin D level was 16.3 ± 11.4 ng/mL. Only 11% of kidney transplant patients, within four months after transplantation, had a normal level of vitamin D (> 30 ng/mL). There was no significant difference between the two groups for patients’ characteristics (P > 0.05). Vitamin D levels, before transplantation and at the time of detecting CMV Ag or at the end of follow-up period in patients without CMV, were not significantly different between the two groups (P > 0.05). However, vitamin D levels decreased in patients with CMV, while it increased in CMV Ag negative patients, which was statistically significant (P = 0.037).. Only 11% of kidney transplant patients, even with a successful transplantation of the kidney and with an acceptable performance of the transplanted kidney, had an adequate level of vitamin D. Although, we did not find any significant association between vitamin D levels and CMV infection during a 4-month follow-up after kidney transplantation. It was observed that, compared with the time before transplantation, vitamin D levels decreased in patients with CMV, while it increased in CMV negative patients..

We reported a case of hemophagocytic syndrome complicating microscopic polyangitis presented by crescentic glomerulonephritis.. A 22-year-old female patient originated from Dakar, Senegal presented with nephrotic syndrome and rapidly progressive glomerulonephritis. On physical examination, we noticed hyperchromic diffuse punctilious purpura skin lesions predominant on the trunk, the neck and the upper thigh. Immunology investigations revealed strongly positive anti SSA/Ro and anti-SSB. Anti-neutrophil cytoplasmic antibodies had positive results with a peri-nuclear type fluorescence, specific to myeloperoxidase. In optic microscopy, renal biopsy showed a crescentic glomerulonephritis with circumferential cellular and fibrous proliferation affecting 85% of glomeruli. The diagnosis of microscopic polyangitis with renal and skin involvement was retained. The patient received methylprednisolone and cyclophosphamide 700 mg/m2 every 15 days for the first 3 pulses and every 21 days thereafter. After the 5th month, she developed obnubilation, fever and central pancytopenia. Bone marrow aspiration was performed, which showed medullary invasion by macrophages with signs of hemophagocytosis. Diagnosis of hemophagocytic syndrome complicating a microscopic polyangitis was retained and methylprednisolone pulses started. The patient was under hemodialysis after follow-up of about 9 months with stable clinical state.. The occurrence of SAM in pauci-autoimmune vasculitis is rarely described, particularly in Africa. Our case is an illustration of the reality of this association..

Several studies have been conducted on the relationship between a number of human leukocyte antigen (HLA) alleles and cytomegalovirus infection (CMV), in kidney transplant recipients, after transplantation. However, only a limited number of HLAs have been investigated, so far, and the results have been contradictory.. This study aimed to investigate the relationship between 59 HLA alleles and the CMV infection, in transplant recipients, after kidney transplantation..Patients and This retrospective cohort study was conducted on 200 patients, receiving a kidney transplant, in Baqiyatallah Hospital, in Tehran, during 2013. Throughout a one-year follow-up of kidney transplant recipients, in case of detecting the CMV antigen in patients’ blood, at any time, they were placed in the group of patients with CMV infection, whereas, if no CMV-specific antigen was developed, over a year, patients were placed in the group of patients without CMV infection, after transplantation. This study investigated the relationship between CMV infection in kidney transplant recipients and 59 HLA alleles, including 14 HLA-A, 28 HLA-B, and 17 HLA-DRB1 cases.. Of all participants, 104 patients (52%) were diagnosed with CMV infection. There was no significant difference between the two groups, with and without CMV infection, in terms of patient’s characteristics. The CMV infection, in patients receiving a transplanted organ from deceased donor, was significantly more prevalent than in those receiving kidney transplant from living donor (63% vs. 39%, respectively, P = 0.001). Recipients with HLA-B44 were more infected with CMV compared with patients without this allele (80% vs. 50%, respectively, P = 0.024); on the contrary, kidney recipients with HLA-DRB1-1 were less infected with CMV than patients without this allele (31% vs. 55%, respectively, P = 0.020). There was no significant relationship between CMV infection and other HLA alleles. Results of multivariate logistic regression analysis showed that deceased donor renal transplantation (OR = 3.018, 95%CI: 1.662 - 5.480, P < 0.001), presence of HLA-B44 (OR = 4.764, 95%CI: 1.259 - 18.032, P = 0.022) and lack of HLA-B8 (OR = 3.246, 95%CI: 1.030 - 10.230, P = 0.044) were the independent risk factors for developing CMV infection, after kidney transplantation.. The findings of this study showed that deceased donor renal transplantation and the presence of HLA-B44 can make the kidney recipient susceptible to CMV infection after kidney transplantation; on the other hand, the presence of HLA-B8 can have a protective effect..

Restless legs syndrome (RLS) may be associated with increased morbidity and mortality among end-stage renal disease (ESRD) patients; however, it is a disorder that is neglected in dialysis centers.. The goal of this study was to investigate the clinical factors associated with RLS among ESRD patients..Patients and This cross-sectional study was conducted on ESRD patients undergoing maintenance hemodialysis (HD) in three HD centers in Ahvaz city in Southwest Iran. Blood samples were obtained prior to a dialysis session to check the routine laboratory test results and assess the adequacy of dialysis. The presence of RLS was assessed by using the international RLS study group (IRLSSG) diagnostic criteria. The IRLSSG rating scale was also used to evaluate the severity of the RLS symptoms.. Of the 139 HD patients enrolled in this study, 60 were female (43.2%) and 79 were male (56.8%), with a mean age of 51.82 ± 13.31 years. The prevalence of RLS was 15.8% (22 patients), with 50% of them (11 patients) having severe or very severe symptoms. There was a significant relationship between RLS and longer durations of dialysis (P < 0.001). The mean level of serum ferritin was lower in patients without RLS, but it was not significant (P = 0.065). No significant differences were found according to age, gender, dialysis shifts, and hemoglobin (Hb) level among patients with and without RLS.. We conclude that a significant percentage of ESRD patients undergoing maintenance HD have severe or very severe RLS symptoms. The presence of RLS is associated to longer durations of dialysis..
