    Purpose: To report eye bank records for pediatric keratoplasty in Iran between 2006 and 2019. Methods: In a retrospective study, all electronic records of the Central Eye Bank of Iran for pediatric keratoplasty between April 2006 and March 2019 were analyzed in terms of indications for keratoplasty, surgical techniques, their corresponding trends, and post-transplantation graft clarity. Results: Our database included 2178 eyes from 2050 pediatric cases. The leading indications for keratoplasty included acquired nontraumatic diseases (75.8%), congenital abnormalities (12.7%), corneal regraft (8.3%), and acquired traumatic diseases (3.2%). Keratoconus was the most common acquired nontraumatic cause (58%) and more common in the age group >12 years than those ≤12 years (P < 0.001). Congenital corneal abnormalities and regrafts were more common in the age group ≤12 years (both Ps < 0.001). The most common surgical technique was penetrating keratoplasty (PKP, 90.9%) followed by deep anterior lamellar keratoplasty (DALK, 7.3%), Descemet stripping automated endothelial keratoplasty (DSAEK, 1.1%), anterior lamellar keratoplasty (0.5%), and keratolimbal allograft transplantation (0.2%). DSAEK was more common in the age group ≤12 years (P = 0.002), which, unlike PKP and DALK, showed a significant ascending trend over the 14-year period (P = 0.018). Posttransplantation graft clarity was 96.8%. Conclusion: Keratoconus was the leading indication for pediatric keratoplasty in Iran. Although PKP was the predominant keratoplasty procedure for the treatment of pediatric corneal disorders, it showed a significant descending trend over the 14 years

    Percutaneous nephrolithotomy (PCNL) has been the preferred procedure for the removal of large renal stones in Iran since 1990. Recently, we encountered a series of devastating neurologic complications during PCNL, including paraplegia and hemiplegia. There are several reports of neurologic complications following PCNL owing to paradoxical air emboli, but there are no reports of paraplegia following PCNL. Materials and Methods: We retrospectively reviewed the medical records of patients who had undergone PCNL in 13 different endourologic centers and retrieved data related to neurologic complications after PCNL, including coma, paraplegia, hemiplegia, and quadriplegia. Results: The total number of PCNL procedures in these 13 centers was 30,666. Among these procedures, 11 cases were complicated by neurologic events, and four of these cases experienced paraplegia. All events happened with the patient in the prone position with the use of general anesthesia and in the presence of air injection. There were no reports of neurologic complications in PCNL procedures performed with the patient under general anesthesia and in the prone position and with contrast injection. Conclusions: It can be assumed that using room air to opacify the collecting system played a major role in the occurrence of these complications. Likewise, the prone position and general anesthesia may predispose to these events in the presence of air injectio

    Aim. Sonography has been brought in percutaneous nephrolithotripsy (PCNL) as an adjunct to or substitute for X-ray to restrict radiation exposure. Tis study was designed to investigate the possible predictors for the success of the solo sonographically guided PCNL. Methods. 148 consecutive cases were prospectively enrolled. All steps of PCNL were performed solely with sonography guidance under spinal anesthesia. Residual stones were evaluated the day afer surgery using sonography and plain radiography. Results. Te mean age was 46 ± 15 years; 40% of kidneys had hydronephrosis. Te mean stone burden was 504 ± 350 mm2. Te mean duration of surgery was 43 ± 21 minutes. Te early stone-free rate was 92% in inferior or middle calyceal stones, 89.5% in single pelvic stones, 81.5% in partial staghorn stones, and 61.9% in staghorn stones. Te mean residual stone size was 13 ± 8 mm. Logistic regression showed that a lower age and a larger stone burden signifcantly predicted positive residual stones. Fifeen percent of patients presented with grade I or II and six percent showed grade III complication based on Clavien classifcation. Tere was no cases of organ injury or death. Conclusion. Solo ultrasonographically guided PCNL under spinal anesthesia is feasible with an acceptable stone-free rate and complication rate

    This study was designed to determine the correlation of hepatitis B virus surface Ag (HBsAg) variations with the clinical/serological pictures among chronic HBsAg positive patients. The surface gene (S-gene) was amplified and directly sequenced in twenty-five patients. Eight samples (group I) contained at least one mutation at the amino acid level. Five showed alanine aminotransferase (ALT) levels above the normal range of which only one sample was anti-HBe positive. Group II (17 samples) did not contain any mutation, 4 were anti-HBe positive and 9 had increased ALT levels. In both groups, from a total of 18 mutations, 5 (27.5%) and 13 (72.5%) occurred in anti-HBe and HBeAg positive groups respectively. The small number of amino acid mutations might belong to either the initial phase of chronicity in our patients; or that even in anti-HBe positive phase in Iranian genotype D-infected patients, a somehow tolerant pattern due to the host genetic factors may be responsible

    Introduction: We report a new modified technique of unaltered appendix transfer to ileal pouch and preserving ileocecal segment. This modification enables us to use ileum as the popular type of enteric segment instead of ileocecal segment while using appendix as a catheterizable stoma. Materials and Methods: Forty-five patients (30 men) who needed reconstruction of the lower urinary tract were enrolled for using appendix as a catheterizable stoma. Reservoir was reconstructed using ileal segment. The appendix was circumcised from its base over its pedicle. The spatulated appendix tip was exteriorized as a catheterizable stoma to the skin, preferably umbilicus, and its base was implanted to the ileal pouch. Results: Follow-up records of 38 of 45 patients were available. The median follow-up period was 29 months. The mean intermittent catheterization interval was 4.19 ± 1.6 hours. Urodynamic parameters were evaluated for 18 out of 38 patients. The median maximal pouch capacity determined as 380 mL. The median appendiceal closure pressure was 61 cm H2O. No pouch perforation occurred. Stomal stenosis occurred in 3 patients. They did not catheterize their appendiceal stoma because they restarted catheterization through the urethra. Conclusion: This novel approach enabled us to use ileum as today's more popular type of bowel segment to reconstruct enteric pouch rather than using ileocecal segment, while using appendix as a catheterizable stoma. One of the unique advantages of this technique is that the postponement of clean intermittent catheterization will not result in pouch perforation since the urine will leak when the pouch becomes overfill

    Background: Due to lack of detailed standards of sexual maturity in individuals with Intellectual, sensory and motor disability in Iran and the importance of timing of onset of puberty in these individuals, a study is necessary. By knowing the onset of puberty, physiologic and behavioral changes can be traced in these people, as well as the potential impact of the puberty on the underlying disease can be considered. The aim of the study was to investigate of sexual maturation among boys of special schools of Tehran. Materials and Methods: Cross-sectional study was performed on children and adolescents male students in special school in Tehran at 2013. A random, multistage sample 0f 895 boy students of special schools was taken from 25 special schools in five districts of Tehran city. In this study, symptoms and stages of puberty were identified. Pubertal stages were assessed by visual inspection and palpation based on the rating scales of Tanner. In addition, demographic data such as age, height, weight were collected. Then the data were analyzed and mean age of onset of puberty was determined. Results: The mean age of onset of puberty in boys (Genitalia stage 2) was 13.12 ± 1.84 years and sexual maturation was completed at 16.57 ± 1.34 years. The average height at the onset of puberty (Genitalia stage 2) was 151.1 ± 9.91 cm and the average weight was 48.47 ± 10.14kg. The mean BMI for puberty onset was 20.89 ± 5.43. Conclusion: In our study, the mean age of puberty onset in boys with disabilities was 13.12 ± 1.84 years. Compared to the data from healthy boys, our findings indicate that the mean age of pubertal onset in boys with disabilities in special school is higher than that of their healthy counterparts

    Background and objectives: Optimal surgical management of the neonate with imperforate anus (IA) depends on determining accurate location of muscle complex, pouch of rectum and urethral fistula. The aim of this study was to investigate a novel minimally invasive technique of anorectoplasty assisted by intraoperative sonography pull-through for repair of anorectal malformation and rectourinary fistula.Patients and methods: Eight male patients with imperforate anus aged under 48 h had undergone colostomy. Any associated anomalies were evaluated in cases. After 5-8 weeks, neonates were prepared for anoplasty. After catheterization, sonography of perinea was carried out. Patients were placed in lithotomy position. The accurate position of each required point was determined by this procedure.Results: In all cases, the pouch of rectum to skin distance was in range 1.5-1.8 mm and entrance distance of wire to fistula was maximally 6 mm, just in one patient this value was 7 mm. Anomalies associated with some patients were Down Syndrome, cardiac anomalies, kidney disease .6 out of 8 patients removed urinary catheter after two days and discharged home. Colostomy of all patients was closed after sonography of prinea. After one week and one month follow- up, all patients had an acceptable fecal frequency about 3- 5 times a day.Conclusion:Intra-operative sonography is an applicable procedure to determine correct location of muscle complex, pouch of rectum and uretral fistula to treat IA patients non- invasively. Another interesting point of this study is the ability of non invasive surgery and novel procedure with perfect result
