Case Report: Gut and spleen anomalies associated with DYRK1A syndrome

DYRK1A syndrome has been extensively studied primarily with regard to neurologic and other phenotypic features such as skeleton and craniofacial alterations. In the present paper, we aim to highlight unusual anomalies associated with a DYRK1A mutation: a 17-year-old female patient with language and cognitive delay, microcephaly, and an autistic disorder, who was operated upon for spleen torsion with anomalous gut fixation.

Conservative management of posterior tracheal wall injury by endoscopic stent placement in children: Preliminary data of three cases

The management of tracheal wall lacerations is debated. Current treatments are mainly derived by the experience on adults and include conservative or surgical treatments depending on the clinical condition of the patient. We report our preliminary data with removable tracheal stents in 3 children with tracheal tears and respiratory failure. If performed in specialized centers with appropriate endoscopic and clinical follow-up, airway stents can be considered a valid and safe conservative treatment for tracheal tears and an alternative to intubation or tracheostomy. Further studies are needed to compare different therapeutic options and better define the management and duration of stent treatment.

Serial transverse enteroplasty (STEP) in case of short bowel syndrome: did we achieve our goal? A systematic review

Surveys on Serial Transverse Enteroplasty (STEP) published in international literature (1 January 2003- 31 May 2021) were searched. Articles were included from 17 countries: 1/23 comparative and 22/23 cohort studies. STEP was performed on 308 patients: pediatrics, adults, and mixed ages. Pediatric group included 16 studies and the adult 6. Pre-STEP residual small bowell (SB) length for pediatrics and adults ranged from 18 to 26 cm and from 30 to 70 cm, respectively. Post-STEP increased SB length for pediatrics and adults ranged between 42 and 100% and 50% and 176%, respectively. For pediatrics, enteral autonomy was reached in 32.22% of cases, parenteral nutrition (PN) dependence was 36.11%, a repeated STEP procedure (Re-STEP) was needed in 17.22%, and a bowel transplant was performed in 6.11%. In adults, enteral autonomy was achieved in 52.38%, while PN dependence was 37.1%, and no Re-STEP or transplantation were required. For the mixed group, post-STEP bowel length increased from 2 to 50 cm, enteral autonomy was obtained in 43%, PN dependence was 57%, without reported Re-STEP or transplantation. Mortality rates were between 5.55% (pediatric) and 7.14% (adults). Preoperative length with preservation of ileocecal valve represented the main predictive factors to achieve enteral autonomy.

Restoring gut physiology in short bowel patients: from bench to clinical application of autologous intestinal reconstructive procedures

Introduction: Short bowel syndrome represents the leading etiology that causes intestinal failure both in children and adults. Total parenteral nutrition support has dramatically improved the prognosis for these patients but, if related irreversible complications occur, the alternative is represented by surgery and/or transplantation. Areas covered: Autologous gastrointestinal reconstructive procedures are a feasible, alternative approach with good long-term outcome data inexperienced surgical centers. Expert opinion: Ongoing innovative efforts have driven the surgical options for successful autologous reconstructive surgery: bowel elongation/tapering techniques (LILT, STEP, and the new SILT) together with the 'reversed bowel segment' procedure are now recognized procedures and all must be tailored to the individual patient needs to obtain the optimal result in terms of enteral autonomy. Background laboratory experimentation with new procedures e.g. options for bowel dilation techniques and distraction-induced enterogenesis, may provide additional management and treatment modalities.

Patients with a history of infection and voiding dysfunction are at risk for recurrence after successful endoscopic treatment of vesico ureteral reflux and deserve long-term follow up

Aim of the Study:

Subureteral endoscopic injection of a bulking agent is an attractive alternative to open surgery or antibiotic prophylaxis for vesico ureteral reflux (VUR). Little information is available about long-term risk of recurrence after an initially successful treatment. Aim of this paper was to review short- and long-term success rate of endoscopic treatment in a single Center series after risk stratification of individual patients.

Materials and Methods:

The records of 126 patients who underwent Deflux injection for primary VUR were examined. Indications to treatment were an unvaried high grade VUR (IV-V) at 1 year from diagnosis and/or and recurrent urinary tract infection (UTI) on antibiotic prophylaxis even in the presence of mild grade VUR (III grade). Gender, age and mode of diagnosis, infections (UTI), voiding dysfunctions, VUR grade and side, renal function, number of treatments were correlated to outcome. Long-term evaluation was planned at a minimum of 1 year from the last negative post-injection cystogram (MCUG). A new MCUG and DMSA scan were also offered to those complaining new UTI episodes. Late recurrences were correlated to history and grade of reflux. Data were analyzed with Graph Pad Instat software; the Chi-square test was used for univariate comparisons, the Fisher's exact test for categorical variables.and multiple regression tests for factors influencing outcome.

Results:

M/F ratio was 62 to 64; median age at diagnosis was 28 months. VUR affected 198 renal units. Preinjection VUR grade was I in 1, II in 27, III in 107, IV in 59, and V in 4 units. Reduced DMSA uptake was evidenced in 51 units and scarring in 24. Median age at treatment was 34.5 months, for persistent high grade VUR (IV–V) in 55 patients and recurrent IVU in 92. Two hundred sixty seven injections were performed on 198 ureters. Complete resolution was documented by MCUG at 3-5 months in 68%, low grading < II in 20%, persistence or unsignificant reduction in 11%. Preoperative recurrent UTI, higher grade VUR, and bilaterality were correlated to a poorer surgical outcome. Among 80 successfully treated cases, 12 complained of persistent UTI. Recurrence of VUR was demonstrated in 31% of them. Deteriorated uptake or additional scarring in 25% was independent from VUR recurrence. Preoperative recurrent UTI and voiding dysfunction correlated significantly to late outcome.

Conclusions:

Preoperative recurrent IVU, together with high-grade reflux, seem to correlate to lower success rate of Deflux injection for primary VUR. Even after successful endoscopic treatment, long-term surveillance may be needed among these cases, mainly if voiding dysfunction is also recorded. Late recurring VUR must be actively excluded in case of new IVU episodes.

Post-traumatic superior sagittal sinus thrombosis. Case report and analysis of the international literature

The objective of this study is to focus attention on cerebral venous sinus thrombosis (CVST), a rather infrequent disease, especially when following closed head injury. Consequently we started from the clinical case report, concerning a patient admitted to our polyvalent ICU in the Hospital of Avezzano (AQ), Italy. The patient was a 15-year-old girl, that developed superior sagittal sinus (SSS) thrombosis following closed head injury (pedestrian run down by a car): owing to slow and progressive onset of deep coma with severe intracranial hypertension, emergency decompressive craniectomy was performed. The result was satisfying: patient conditions progressively improved, with return to consciousness, to good mobility and to good mental status. At present, 1 year after trauma, only mild disability is left over (right hand prehensile strength loss, and slightly moving gait). In conclusion, considering the literature data (intracerebral haematoma and deep coma are poor outcome predictors) and clinical evolution, we decided an aggressive surgical approach to save the patient's life, with satisfying results.

[Mixed venous oxygen saturation monitoring in selected patients in heart surgery]

Continuous SvO2 was monitored in 25 patients undergoing cardiac surgery, selected by preoperative conditions, risk and perioperative indications. SvO2 trends were compared to cutaneous temperature, left atrial pressure and pulse oximetry. The results indicate a good correlation of all trends.
