Polypoid heterotopic gastric mucosa: in terminal ileum causing extensive lower gastrointestinal bleeding without Meckel's diverticulum: a case report.

BACKGROUND: Heterotopic gastric mucosa (HGM) can be located in various parts of the gastrointestinal tract. As a rare anomaly in the small intestine, it can become complicated by intussusception, obstruction, gastrointestinal bleeding, and even peritonitis, leading to death. CASE PRESENTATION: This case report focuses on a 12-year-old Middle Eastern boy who presented with hematochezia and abdominal pain for a couple of days. A tagged Red blood cell (RBC) scan and Technetium scan revealed gastrointestinal bleeding at the lower abdomen, highly suggestive of the diagnosis of Meckel's diverticulum. Subsequently, exploratory laparotomy revealed contiguous and scattered mucosal lesions with multiple polyps of various sizes in the terminal ileum. Meckel's diverticulum was absent, and the patient was treated with resection and primary anastomosis. The resected tissue revealed extensive ectopic gastric mucosa and polypoid tissues. The patient recovered uneventfully and was discharged four days after the surgery. The symptoms did not recur within six months after his surgery. CONCLUSION: Our case demonstrated that despite the rarity of multiple polypoid gastric heterotopias in the terminal ileum, it should be considered as one of the differential diagnoses of gastrointestinal tract bleeding.

Abu Al-Qasim Al-Zahrawi (936-1013 CE), Icon of Medieval Surgery.

Abu al-Qasim Al-Zahrawi (936-1013 common era [CE]), also known in the West as Albucasis, was a great Arab physician and surgeon of the late 10th and early 11th centuries CE. He is best known for his surgical knowledge and expertise. His greatest contribution to medicine is the Kitab al-Tasrif, which includes thirty treatises on medical sciences. His early and great contributions to the field of surgery were seminal. For his endeavors in this field, a number of surgeons and scholars have dubbed him the "Father of Operative Surgery".

Different clinical presentations of choledochal cyst among infants and older children: A 10-year retrospective study.

Choledochal cyst is a rare and often benign congenital cystic dilation throughout the biliary tree. Due to the benign nature of choledochal cyst among early-diagnosed patients, the clinical assumption and diagnosis seem to be of utmost significance. Therefore, we sought to assess different clinical manifestations of choledochal cyst and relevant laboratory findings in infants and older children.Retrospectively, medical records of all patients with the diagnosis of choledochal cyst between 2005 and 2015 were reviewed. Demographic data, initial clinical presentation, positive findings on physical examination, history of any remarkable behavior such as persistent and unexplained crying and poor feeding, and diagnostic imaging modalities were listed. In addition, laboratory values for total and direct bilirubin, alkaline phosphatase, alanine transaminase, aspartate transaminase, prothrombin time, and partial thromboplastin time (PTT) were recorded for each patient. Patients were divided into 2 groups; younger than 1-year-old (infants), and 1 year to 18 years old (older children). Demographic data, clinical data, and laboratory values were compared between the infants and older children.Thirty-two patients with a diagnosis of choledochal cyst were included in the study: 9 patients (28.12%) were infants and 23 patients (71.87%) were older children. Abdominal pain was the most common presenting symptom (62.5%), followed by nausea/vomiting (59.4%) and jaundice (28.1%). None of the patients presented with the classic triad of abdominal pain, jaundice, and right upper quadrant mass. Seventeen older children (73.91%) presented with nausea and vomiting, while 2 subjects (22.22%) in the infantile group presented with this feature (P = .01). Similarly, abdominal pain was found in 20 older children (86.95%); however, none of the infants presented with abdominal pain at diagnosis (P < .001). By contrast, the abdominal mass was more detected in infants than the older children (33.33% vs. 0%, P = .01). In terms of laboratory values, the median PTT was 44 and 36 s in infants and older children, respectively (P = .04).Infants were more likely to present with abdominal mass and older children were more likely to have nausea, vomiting, and abdominal pain. Furthermore, infants had more prolonged PTT than older children, implying a potential bleeding tendency.

Is there any correlation between radiologic findings and eradication of symptoms after pyloromyotomy in hypertrophic pyloric stenosis?

BACKGROUND: Hypertrophic pyloric stenosis (HPS) is one of the most common gastrointestinal disorders during early infancy, with an incidence of 1-2:1000 live births in the world. In this study, we aimed to investigate the correlation between radiologic findings and eradication of symptoms after pyloromyotomy in HPS. MATERIALS AND METHODS: One hundred and twenty-five (102 boys and 23 girls) patients with suspected infantile HPS were treated surgically by Ramstedt pyloromyotomy between March 21, 2004 and March 20, 2014 at paediatric surgery ward of Tabriz Children's Hospital, Iran. The demographic features, clinical findings, diagnostic work-up, operation type and postoperative specifications of the patients were studied retrospectively. RESULTS: Male to female ratio was 4:1. The patients were 16-90 days of old and the mean age was 39 ± 1.42 days. The range of pyloric canal length was 7.60-29.00 mm and the mean length was 19.54 ± 3.42 mm. Pyloric muscle diameter was 2.70-9.00 mm, and the mean diameter was 4.86 ± 1.14 mm. Seventy-two percent of patients had episodes of vomiting after operation. Mean time of persistence of vomiting after pyloromyotomy was 15.73 ± 0.15 h. Mean discharge time was 55.22 ± 0.08 h. Radiologic findings did not show any significant correlation with persistence of vomiting or discharge time. CONCLUSION: The present study revealed that radiographic findings could not predict postoperative symptom eradication after pyloromyotomy in HPS.

A rare case of aphallia with right kidney hypoplasia and left kidney dysplasia.

Aphallia or penile agenesis is an extremely rare congenital anomaly with an estimated incidence rate of 1 in 10 to 30 million births. We report a rare case of aphallia with right kidney hypoplasia and left kidney dysplasia in a 10-day old Iranian-Azeri male. The patient had creatinine rise and renal failure due to dysplastic left kidney and hypoplastic right kidney and expired on fifth day of admission. There were only six cases of renal malformation associated with aphallia in the literature review. Three of the cases were complicated by Potter sequence and one of them was accompanied by chronic renal failure. Our case had a unique presentation because of bilateral renal malformation and subsequent renal failure without the Potter sequence.

DR. SAKINEH PARI, THE FIRST IRANIAN FEMALE SURGEON.

Modern surgery has been evolved in Iran by the establishment of Dar al-Funun and Tehran University in 1851 and 1934 respectively. Professor Yahya Adl established the first academic department of surgery at Tehran University in 1930s and he is known as the father of modern surgery in Iran. Until recent times, women's options for obtaining advanced surgical training programs were severely restricted all over the world. Dr. Sakineh Pari, born in 1902, was the first Iranian female surgeon. The aim of this article is to introduce Dr. Sakineh Pari as the first woman surgeon in Iran.

Tumour necrosis factor-alpha gene polymorphisms in Iranian patients with biliary atresia.

BACKGROUND: Biliary atresia (BA) is a progressive inflammatory destructive process of the bile ducts. This study evaluated the relationship between single-nucleotide polymorphisms in the promoter region of tumour necrosis factor-alpha (TNF-α) gene and bilaiary atresia. MATERIALS AND METHODS: Genomic deoxyribonucleic acid from 16 patients with established diagnosis of BA and 36 patients with INC was obtained. The genotypes of TNF-α-1031 (T/C) and TNF-α-308 (G/A) were determined using the restriction fragment length polymorphism-polymerase chain reaction and the results were analysis with proper statistic software. RESULTS: The frequencies of T/T, T/C in TNF-α-1031 and G/G, G/A in TNF-α-308 were as same as control group. Moreover, we have same deduction for allele frequency and haplotypes analysis (T allele: 84.37%; G allele: 87.5%) in BA patients (T allele: 80.56%; G allele: 86.11%) in controls. In all cases variants of polymorphism did not affect the severity or incidence of BA disease. CONCLUSION: although no significant associations were found between BA and control groups, it seems meaningful that since the nature of BA is multi factorial. Next step will be considering a new target such as downstream modulation of the TNF-α pathway or other cytokines and chemokines which act directly/indirectly.

Hydatid cyst in children: A 10-year experience from Iran.

BACKGROUND: Hydatid disease is one of the major world-wide health problems especially in endemic countries. Due to lack of statistics about this disease, various aspects of hydatidosis in children in North-West of Iran have been studied in this study. MATERIALS AND METHODS: We studied 59 children with hydatidosis referring Tabriz Children Hospital, Tabriz, Iran from 2001 up to 2011. We surveyed chief complaint of patients, number, size and location of cysts in children and also we studied cysts as if they are infected or ruptured or not. RESULTS: Average age of 59 patients (32 [54.2%] males and 27 [45.8%] females) was 7.93 ± 3.0. The most common chief complaints were cough and pain. Number of cysts was higher in females (2.00 ± 2.8 vs. 1.52 ± 1.0). The most common locations of cysts are lung and liver (52 patients); however, other organs had been also affected. CONCLUSIONS: Lung hydatidosis is more common than hepatic hydatidosis in children than adults and it is more frequent in males. Hydatid disease should be considered in differential diagnoses of liver and lung cystic lesions in children.

Acute and chronic pathological effects of sulfur mustard on genitourinary system and male fertility.

PURPOSE: To review the acute and chronic pathological effects of sulfur mustard on the genitourinary system and male fertility. MATERIALS AND METHODS: We searched PubMed and Google Scholar to find studies related to the sulfur mustard-induced genitourinary effects and male infertility. Information in the abstracts of non-English related papers as well as those in the proceedings of congresses on sulfur mustard were reviewed as well. RESULTS: In acute phase after sulfur mustard exposure, evidences are in favor of microscopic and macroscopic renal lesions, very low androgen levels, and impaired spermatogenesis. Several years following sulfur mustard exposure, the long-term pathological effects vary from the renal function impairment to the gonadal damage, in particular the spermatogenesis. Nevertheless, carcinogenic effect of sulfur mustard on the genitourinary system as well as the prevalence of male infertility among sulfur mustard-exposed veterans in the chronic post-exposure phase is still unclear. CONCLUSION: Sulfur mustard causes both acute and chronic injuries to different parts of the genitourinary system.

Contributions of Medieval Islamic physicians to the history of tracheostomy.

Tracheostomy was first described by Greco-Roman physicians, including Paulus of Aegina. Medieval Islamic clinicians extended the Greco-Roman ideas with substantial contributions to the field of surgery, including tracheostomy. Although Al-Zahrawi (936-1013 CE) stated that he had not heard or read of any Islamic physicians having performed tracheostomy, there is evidence that many prominent Islamic surgeons did practice this lifesaving procedure during medieval times. Throughout the Islamic Golden Age, Muslim physicians advanced the practice of tracheostomy with many modifications of the procedure, instrumentation, and adjuvant medicinal prescriptions.

Role of Helicobacter pylori in the pathogenesis of infantile hypertrophic pyloric stenosis.

OBJECTIVES: To investigate the possible correlation between infantile hypertrophic pyloric stenosis (IHPS) and Helicobacter pylori infection. MATERIALS AND METHODS: In a case-control study, 20 infants with confirmed IHPS (Group 1) and 30 age-matched healthy infants (Group 2) were enrolled for the assessment of H. pylori infection. Serological testing of anti-H. pylori antibody (IgG) was performed preoperatively on all infants and their mothers. Also, H. pylori stool antigen test (HpSA) was carried out preoperatively on all infants in both groups. Statistical analyses were performed with Chi-square test, Fisher's exact test, Mann-Whitney U test, and Independent-Samples T test. RESULTS: There were 20 patients in group 1 (18 boys, 2 girls) and 30 infants in group 2 (30 boys). The mean age in groups 1 and 2 were 42.40±18.09 days and 44.67±12.65 days, respectively. The numbers of positive HpSA and positive anti-H. pylori antibody both in infants and mothers were comparable between the two groups (P>0.05). The median titres of H. pylori stool antigen were not comparable between the two groups (0.20 ng/dL in group 1 vs 0.57 ng/dL in group 2; P=0.02). CONCLUSIONS: H. pylori does not seem to be in a causative linkage with IHPS.

Associated congenital anomalies between neonates with short-gap and long-gap esophageal atresia: a comparative study.

BACKGROUND: Predicting the presence of long-gap esophageal atresia (EA) prior to the surgery is of clinical importance. No comparison between short-gap and long-gap EA for the prevalence of VACTERL and non-VACTERL-type anomalies has yet been performed. OBJECTIVE: The aim of this study was to compare VACTERL and non-VACTERL-type anomalies between patients with short-gap and long-gap EA. METHODS: Retrospectively, medical records of all newborns managed for EA/tracheoesophageal fistula (TEF) in Tabriz Children's Hospital and Tehran Mofid Hospital between 2007 and 2010 were evaluated. Demographic data and associated anomalies including both the VACTERL and non-VACTERL-type defects were listed. The VACTERL spectrum defects covered vertebral/costal, anorectal, cardiovascular, TEF, and renal- or radial-type limb anomalies. The non-VACTERL-type anomalies included hydrocephalus, orofacial defects, respiratory system anomalies, gastrointestinal anomalies, genital anomalies, and non-VACTERL limb defects. Demographic data, and the VACTERL and non-VACTERL-type anomalies were compared among children with long-gap EA and those with short-gap EA. RESULTS: Two hundred and seventy-six children were included in the study: 230 (83.3%) in the short-gap EA group and 46 (16.7%) in the long-gap EA group. Although prevalence of the VACTERL spectrum anomalies did not differ between the two groups, the non-VACTERL anomaly was more common in the long-gap EA group (P = 0.02). Among the VACTERL-type defects, TEF was detected in 30 (65.2%) and 218 (94.7%) patients in long-gap and short-gap EA groups, respectively (P = 0.0001). CONCLUSION: The non-VACTERL-type anomalies, but not the VACTERL spectrum defects, are more frequent in patients with long-gap EA than those with short-gap EA.

Bowel perforation by ventriculoperitoneal shunt catheter mimicking gastroenteritis.

Colon perforation is a rare and serious complication of ventriculoperitoneal shunt. The authors report a 7-month-old male infant with vomiting and watery diarrhea after colon perforation by a ventriculoperitoneal shunt. A minimal laparotomy incision was performed accurately where preoperative colonoscopy had detected the penetration site of shunting tube in the left colon.

Supernumerary nostril together with esophageal atresia, imperforate anus and patent ductus arteriosus: a case report and review of the literature.

Supernumerary nostril is an extremely rare congenital entity which results from aberrant embryological development. The review of the literature reveals that only 30 cases of supernumerary nostril have been reported. We report a rare case of supernumerary nostril in association with esophageal atresia, imperforate anus, and patent ductus arteriosus. To our knowledge, this is the first case of supernumerary nostril which has been accompanied by three other congenital anomalies. In addition to the presented case, we review all the literature cases of supernumerary nostril.

The role of prophylactic chest drainage in the operative management of esophageal atresia with tracheoesophageal fistula.

INTRODUCTION: Anastomotic leakage and respiratory complications are among the most common and potentially life-threatening complications following the surgical repair of esophageal atresia. Controversies exist regarding the efficacy of prophylactic extrapleural chest tube (EPCT) drainage in patients who have undergone repair of esophageal atresia. MATERIALS AND METHODS: In this prospective study, 50 newborns with esophageal atresia and distal tracheoesophageal fistula (EA-DTEF) were randomized into two groups, with no significant differences regarding gender ratio, birth body weight and delivery status. Group 1 (n = 29) underwent a right thoracotomy and a single-stage extrapleural esophageal anastomosis. Group 2 (n = 21) received additionally an intraoperative EPCT next to the anastomosis. These groups were then compared with regard to postoperative respiratory complications (such as respiratory distress, pneumonia, pneumothorax, lung collapse, and apnea), anastomotic leakage, need for mechanical ventilation, time on mechanical ventilation, and outcome. Statistical analyses were performed with Mann-Whitney U test, Fisher's exact test, and binary logistic regression analysis. RESULTS: The rates of respiratory complications and anastomotic leakage, need for mechanical ventilation, time on mechanical ventilation, and mortality rate were comparable between the two groups (P > 0.05). Mortality was associated with respiratory complications (P = 0.003) and anastomotic leakage (P = 0.007). CONCLUSION: It seems that prophylactic EPCT drainage does not decrease the early postoperative respiratory complications and mortality rates in newborns with EA-DTEF.

Transanal one-stage endorectal pull-through for Hirschsprung's disease: a comparison with the staged procedures.

Transanal one-stage endorectal pull-through (TOSEPT) has been presented as the most recent progression in treatment of Hirschsprung's disease (HD), which may be able to replace various previous techniques. This prospective study was designed to compare the efficacy and probable complications of the commonly used open surgery with those of TOSEPT technique in management of HD. Forty-two children (35 boys and 7 girls) between 3 days and 12 years of age underwent surgical treatment for HD-all after being diagnosed by barium enema over an 18-month period. In a manner of systematic random selection, 21 patients were operated by TOSEPT and the other 21 by Swenson procedures. All patients were followed-up at least for 12 months after hospital discharge. The necessary data containing age, sex, length of the resected aganglionic segment, intraoperative details, duration of hospital stay and postoperative functional results or complications were collected during hospitalization and follow-up period. There was no significant difference in age at the first operation, sex distribution and length of resected bowel between the two groups. Rate of postoperative complications were significantly higher in Swenson procedure group (P < 0.01). Narcotics were needed in all patients of Swenson procedure group but only in two patients operated by TOSEPT also required laparotomy (P < 0.001). The hospitalization period of TOSEPT group was also less than that of Swenson group (P < 0.001). The total cost of treatment by Swenson procedure is considerably higher than by TOSEPT. TOSEPT can significantly diminish postoperative pain, surgical complications, hospital stay and cost burden caused by Hirschsprung's disease. Besides, this procedure is cosmetically preferable because no visible scar remains.

Congenital malformations of the lung.

Congenital malformations of the lung are rare and vary widely in their presentation and severity. The most common manifestation of the congenital cystic disease of the lung at newborn and early infancy is respiratory distress. Later on in life, cysts usually lose this compressive character and may remain asymptomatic until infection occurs, while producing cough, dyspnea and thoracic pain. The purpose of this study is to review authors institutional experience of congenital cystic lung disease, with specific reference to diagnosis, treatment, as well as outcome, furthermore, to present some cases with unusual clinical manifestations.
