No full textIMPACT OF PRIMARY SURGICAL APPROACH IN THE MANAGEMENT OF THE IMPALPABLE TESTIS
No full textThere is no univoque opinion about the place of preoperative studies in nonpalpable testes. During a 6.5-year period, we operated on 296 impalpable testes in prepubertal boys. A combined inguinal-abdominal approach was used in all cases verifying the eventual abdominal testis and its exact vascular anatomy before any manipulation of the cord was undertaken. Forty-five testes (15.2 %) were canalicular, 142 (48 %) were abdominal, 5 (1.7 %) dysgenetic and 104 (34.1 %) absent (agenesis or vanishing testis). Of the abdominal testes, 122 underwent a standard orchidopexy in dartos pouch, 11 a staged repair, 8 a Fowler-Stephens operation and 1 orchiectomy. All means of investigation for impalpable testes are either unreliable, too expensive or too invasive for routine use, and in most cases, a surgical exploration has to be performed anyway. The primary surgical approach has the most favorable cost/benefit ratio, being diagnostic and therapeutic at one time. Provided the exploration is performed correctly, all the advantages of previous laparoscopy can be achieved with surgery alone
Biliary atresia associated with multiple unrelated anomalies: what about it?
No full textThe prognosis of extrahepatic biliary atresia (EHBA) and multiple apparently not linked anomalies has never been disclosed. We reported a rare case affected by biliary, anorectal and esophageal atresia, and collected the uncommon associations of EHBA with multiple unrelated congenital defects to make known the prognosis. An elevated rate of hepatic failure despite surgery and an early poor outcome were found in the above-mentioned associations. A liver transplantation at the first months of life could be considered to improve outcome
Feeding and Swallowing Disorders in Esophageal Atresia Patients: A Review of a Critical Issue
No full textFeeding and swallowing disorders are commonly seen in clinical practice in infants and children treated for esophageal atresia with or without tracheoesophageal fistula. Nevertheless, only few authors have addressed these issues. This review aims to describe the feeding and swallowing disorders encountered, focusing on pathophysiology, normal development of swallowing and feeding abilities, and possible rehabilitation therapies to prevent or correct these disorders
Side effects to levamisole given to neoplastic patients as adjuvant to surgery: A new case of agranulocytosis
No full textSide-effects to levamisole given as adjuvant to surgery in a consecutive series of 203 neoplastic patients are reported: Thirty-four patients (16.7%) suffered gastric adverse reactions; 8 (3.9%) allergic; 6 (2.9%) intestinal; 6 (2.9% neurologic; 4 (1.9%) severe hyperthermia (more than 40.5 degrees C); 3 (1.4%) flu-like illness; 1 (0.4% leucopenia; and 1 (0.4%) agranulocytosis. Withdrawal rate was 5.4% or 11 patients. Side effects appeared sex-related (39.0% in females, 17.7% in males; with seven female dropout out of 11), unrelated to other eventual adjuvant treatments, and reappearing at a new challenge with levamisole. The opportunity of very close control of patients taking levamisole for at least the first months is discussed
Laryngotracheal abnormalities in esophageal atresia patients: A hidden entity
No full textImportance: Presence of laryngotracheal abnormalities is associated with increased morbidity and higher mortality rate in esophageal atresia patients.Objective: Determine the prevalence of laryngotracheal abnormalities (LTA) in a prospectively collected cohort of patients treated for esophageal atresia and/or tracheoesophageal fistula (EA/TEF). Analysis of the impact of those airway anomalies in early post-operative outcomes was performed.Patients and Methods: This was a review of a prospectively collected database, including patients from January 2008 to December 2017. Patients enrolled in the present study were treated in a high-volume referral center. Present study included all newborn-infants consecutively treated for EN/TEF. All patients were evaluated by flexible laryngotracheoscopy performed under local anesthesia in spontaneous breathing. In case of airway malformation suspected during flexible endoscopy, a rigid endoscopy was performed to complete airway assessment. If post-operative respiratory symptoms (noisy breathing, respiratory difficulty, failure to extubate, or difficulty feeding) were noted, a second laryngotracheoscopy was performed. Primary study outcome was to evaluate the prevalence of LTA in EA/TEF infants, characterizing of LTA, and their impact on early post operative outcomes. Those primary study outcomes were planned before data collection began.Results: During the study period 207 patients with EA/TEF were treated. LTA had a period prevalence of 40.1% (83/207). Although no differences were recorded in terms of demographics and clinical presentation, LTA+ infants more frequently required tracheostomy (12/52, 23% vs. 0/124, 0%; p 0.0001) and were at increased risk of death (12/83, 14% vs. 5/124, 4%; p 0.009) in comparison with EA/TEF without LTA.Conclusions: Present data suggest a high prevalence of congenital LTA in patients affected by EA. Most of the abnormalities are congenital and a high proportion of patients with LTA require a tracheostomy. Mortality significantly correlates with the presence of LTA. Systematic airway endoscopic preoperative evaluation has to be pushed forward to minimize LTA-related morbidity and mortality
Influence of theophylline on both bronchoconstriction and plasma extravasation induced by acetaldehyde in guinea-pigs
No full textAcetaldehyde administered intravenously at various doses (20, 40 and 80 mg/kg) elicits a dose-dependent increase in intratracheal pressure (ITP) and a proportional rise in histamine blood concentration in anaesthetized guinea-pigs. Similar effects were observed in ovalbumin-sensitized guinea-pigs upon aerosol of acetaldehyde (20 mg/ml) which has been administered at the flow rate of 0.1 ml/min for 2 min. Theophylline (CAS 58-55-9) antagonized both the increase of ITP values and the rise of histamine in the blood caused by acetaldehyde given intravenously (ED50 = 5.8 mg/kg i.v.) or by aerosol (ED50 = 4.9 mg/kg i.v.). Furthermore, in animals where combined treatment with pyrilamine (2 mg/kg i.v.) and captopril (2 mg/kg i.v.) resulted in a remarkable potentiation of the bronchoconstrictor response to acetaldehyde (20 mg/kg i.v.), the administration of theophylline (5 mg/kg i.v.) or of the substance P (SP) receptor antagonist, [D-Pro4, D-Trp7.9] SP 4-11 (10 mg/kg i.v.) reduced the augmented action of acetaldehyde on respiratory airways induced by captopril by more than 50%. Moreover, the bronchoconstriction induced by acetaldehyde (40 mg/kg i.v.) was also associated with a significant increase of extravasation of Evans blue in tracheal tissue. Both these effects of acetaldehyde were inhibited by theophylline (10 mg/kg i.v.), whereas a NK1-TK (neurokinin 1-tachykinin) receptor antagonist (412 micrograms/kg i.v.) reduced (81%; p < 0.001) only the vascular permeability changes caused by acetaldehyde.(ABSTRACT TRUNCATED AT 250 WORDS
