Intracranial bleeding risk after minor traumatic brain injury in patients on antithrombotic drugs.

BACKGROUND: Intracranial haemorrhage (ICH) risk after minor traumatic brain injury (mTBI) in patients on antithrombotic treatment is unclear. We compared ICH rates in mTBI patients on single, double and no antithrombotic therapy. Antithrombotic drugs encompassed vitamin K antagonists (VKAs), direct oral anticoagulants (DOACs) and antiplatelets. Secondary aim was to identify potential predictors of ICH. METHODS: We retrospectively analysed consecutive adults referred to our emergency department for mTBI. All clinical information was retrieved by patients' charts review. Patients were divided in 5 groups: 1) no antithrombotic users, 2) antiplatelet users, 3) vitamin K antagonist users, 4) direct oral anticoagulants users, and 5) double antithrombotic users. RESULTS: A total of 1846 patients were enrolled, mean age 71 years (IQR 46-83); 1222 (66.2%) were in group 1, 407 (22.0%) in group 2, 120 (6.5%) in group 3, 51 (2.7%) in group 4 and 46 (2.5%) in group 5. At entry, 1387 (75.1%) patients underwent brain CT, 787 (64.4%) in group 1, 387 (95.1%) in group 2, 119 (99.2%) in group 3 and 51 (100%) in group 4 and 43 (93.5%) in group 5. ICH was documented in 36 patients (4.6%; CI 95%: 3.2-6.3) in group 1, 22 (5.9%; CI 95%: 3.6-8.5) in group 2, 5 (4.2%; CI 95%: 1.4-9.5) in group 3, 2 (3.9%; CI 95%: 0.5-13.5) in group 4 and 3 (7.0%; CI 95%: 1.5-19.1) in group 5 (p-value for across groups comparison = 0.86). At multivariable analysis GCS < 15 (OR 7.95 CI 95%: 3.12-20.28), post-traumatic amnesia (OR 6.49; CI 95%:3.57-11.82), vomiting (OR 4.45 CI 95%:1.47-13.50), clinical signs of cranial fractures (OR 8.41 CI 95%: 2.12-33.33), scalp lesions (OR 2.31 CI 95%: 1.09-4.89), but none of antithrombotic drugs were independently associated with ICH. CONCLUSION: mTBI-related ICH rate was similar in patients with and without antithrombotic use. Potential predictors of ICH can be drawn from patients' clinical examination.

Metabolic abnormalities linked to an increased cardiovascular risk are associated with high-grade prostate cancer: a single biopsy cohort analysis.

BACKGROUND: Smoking, hypertension, abdominal obesity and metabolic abnormalities have been considered individual factors involved in prostate cancer (PCa) pathogenesis. All of these factors are used to define the individual cardiovascular risk (CVR). The aim of our study was to evaluate the association between CVR and PCa diagnosis and grade among a consecutive series of men undergoing prostate biopsy. METHODS: From 2010 onwards, consecutive patients undergoing 12-core prostate biopsy were enrolled. Body mass index was measured before the biopsy. Blood samples were collected and tested for: PSA, fasting glucose, triglycerides and high-density lipoproteins. Blood pressure was also recorded. Metabolic syndrome was defined according to the Adult Treatment Panel III and CVR according to the European Association of Cardiologist Guidelines. We evaluated the association between CVR and PCa biopsy Gleason score using logistic regression analyses. RESULTS: Five hundred and eighty-four patients were enrolled. Four hundred and six patients (70%) presented a moderate/high CVR. Two hundred and thirty-seven (40.6%) patients had cancer on biopsy; 157 with moderate/high CVR and 80 with low/no CVR (P=0.11). Out of the 237 patients with PCa, 113 had a Gleason score 6 and 124 a Gleason score ⩾7. Out of them, 92/124 (75%) presented a moderate/high CVR (P=0.004). Moderate/high CVR was not associated with an increased risk of PCa (odds ratio (OR): 0.741, confidence interval (CI): 0.474-1.156; P=0.186) but with an increased risk of Gleason score ⩾7 (OR: 2.154, CI: 1.076-4.314; P=0.030). CONCLUSIONS: In our study, a moderate/high CVR is associated with an increased risk of a high-grade Gleason score when PCa is diagnosed on biopsy. Although these results should be confirmed in multicentre studies, patients with moderate/high CVR should be carefully evaluated for PCa diagnosis.

Pulmonary hypertension in neonates with high-risk congenital diaphragmatic hernia does not affect mid-term outcome.

PURPOSE: Congenital diaphragmatic hernia (CDH) presents with a broad spectrum of severity, depending on the degree of pulmonary hypoplasia and persistent pulmonary hypertension (PPH). It is currently not clear whether pulmonary hypertension may affect late morbidity. Aim of the present study was to evaluate the influence of PPH on mid-term morbidity in high-risk CDH survivors. METHODS: All high-risk (prenatal diagnosis and/or respiratory symptoms within 6 h of life) CDH survivors, treated between 2004 and 2008 in our Department were followed up in a multidisciplinary outpatient clinic as part of a longitudinal prospective study. Auxological, gastroesophageal, pulmonary and orthopedic evaluations were done at specific time-points (at 6, 12, and 24 months of age). Patients were grouped depending on the presence/absence of pulmonary hypertension (defined by expert pediatric cardiologists after echocardiography). Paired t-test and Fisher's exact test were used as appropriate. P < 0.05 was considered significant. RESULTS: 70 survivors out of a total of 95 high-risk CDH infants treated in our Department attended our follow-up clinic and were prospectively evaluated. 17 patients were excluded from the present study because no clear data was available regarding the presence/absence of PPH during the perinatal period. Moreover, 9 infants were not enrolled because they did not reach at least 6 months of age. A total of 44 survivors were finally enrolled since they met the inclusion criteria. 26 infants did not present with PPH during the first hospital admission, while 18 had PPH. The 2 groups did not differ with regard to any of the outcomes considered at follow-up (p > 0.2). CONCLUSION: In our cohort of high-risk CDH survivors, PPH was not found to affect late sequelae at mid-term follow-up. This may indicate that postnatal pulmonary development is not (always) influenced by perinatal PPH. Nevertheless, a longer follow-up and more patients are needed to properly quantify possible late problems in high-risk CDH survivors with associated neonatal PPH.

Antenatal diagnosis of congenital anomaly: a really traumatic experience?

OBJECTIVE: With increasing use of routine prenatal ultrasound, prenatal counseling after diagnosis of congenital malformations is frequently offered to prospective parents. We aimed to assess if the communication of diagnosis of a congenital anomaly in the fetus meets American Psychiatric Association (APA) criteria for trauma in parents. STUDY DESIGN: In the period ranging from 2003 to 2009 a preliminary investigation was conducted with 165 prospective mothers and 91 prospective fathers being interviewed after communication of diagnosis. Analysis of statements was made independently by two psychologists considering the APA definition of trauma. RESULT: A total of 145 mothers and 76 fathers experienced the communication of diagnosis in their fetus as a traumatic event. There was no correlation between type of malformation and trauma nor was there statistical difference between mother and father regarding the stressor. CONCLUSION: Communication of diagnosis of a fetal anomaly can be a traumatic event and should be dealt with consequently. Given the therapeutic value of sharing traumatic experience such practice should be encouraged as part of the consultation process.

Parents' informational needs at the birth of a baby with a surgically correctable anomaly.

Previous studies have assessed informational needs of parents of sick fetuses, neonates and children to identify favourable patterns of physician-parent interaction. The aim of this paper was to assess parents' informational needs before and after the operation when the one affected by a surgically correctable anomaly is a newborn. In the period ranging from 1997 to 2000 all couples with newborns undergoing major surgical procedures at birth, at the Newborn Surgery Unit of the Hospital Bambino Gesù, were surveyed by means of a questionnaire. Thirty couples form the object of the study. The two genders did not show significant difference in any of the considered items. All 30/30 mothers (M; 100%) and 29/30 fathers (F; 97%) had never heard about the anomaly before the diagnosis was established in their baby. All parents (100%) stated that it would be better if the surgeon informed them with written educational material. Principal informational needs before operation regard: the description of the anomaly (M = 10; F = 11) and the prognosis in terms of survival chances of the baby (M = 17; F = 15); after surgery the cause of the anomaly (M = 5; F = 3); the steps of the recovery process (M = 10; F = 12) as well as the quality of their baby's life (M = 9; F = 9). In the immediate perioperative period the surgeon should well address parents' informational needs, which may significantly differ from his communication plan.

Long gap esophageal atresia and esophageal replacement: moving toward a separation?

BACKGROUND/PURPOSE: Treatment of long gap esophageal atresia (EA) is still a major challenge. Gastric transposition and colon interposition are the 2 most popular choices for esophageal replacement, but there is general agreement that the child's own esophagus is the best. The aim of the study was to critically evaluate the feasibility and outcome of primary repair of long gap EA with or without tracheoesophageal fistula (TEF) by direct esophago-esophageal anastomosis as the only technique. METHODS: Seventy-one neonates with EA+/-TEF were considered. Nineteen cases were classified as long gap (> or =3 cm). All infants underwent either primary or shortly delayed repair. In the latter group, a gastrostomy was performed along with an x-ray evaluation of the gap a few days before surgery (mean age, 46.4 days). To avoid disruptive anastomotic force, all infants were kept paralyzed and mechanically ventilated for an additional 6 days after esophageal anastomosis. Before starting feeding, postoperative esophagogram was done on day 7. Endoscopy was done routinely, starting 1 month after surgery; pH monitoring was conventionally performed at 1 year of age or even earlier, should gastroesophageal reflux disease (GERD) be suspected. Follow-up ranged from 11 months to 7 years. RESULTS: In all 19 long gap EA infants an esophago-esophageal anastomosis was performed. Six of them (31%) required an anterior esophageal flap to bridge residual gap. Complications included minor anastomotic leak in 2 cases and anastomotic stricture (<5mm) in 12 (80%) cases, which were treated with an average of 5 dilatations (1 of which with resection of the stricture). GERD occurred in 8 cases (53.3%), of which, 3 required fundoplication. None of the patients had esophageal swallowing difficulties or persistent dysphagia. Two children experienced food aversion. Mean hospital stay was 66.2 (22 to 230) days. There were 4 deaths (very low birth weight, 1; associated anomalies, 1; and late sepsis, 2). CONCLUSIONS: Considering heat gap determination remains imprecise, it seems possible to conclude that in a well-established tertiary care level referral center: (1) long gap EA could be treated successfully with primary repair and anastomosis; (2) strictures and GER represent the most frequent postoperative problem, but additional procedures required seem "acceptable" to maintain the patient's own esophagus and avoid replacement; (3) esophageal substitution in long gap EA should be reserved for cases in which a previous attempt of esophageal reconstruction failed.

Impact of a current treatment protocol on outcome of high-risk congenital diaphragmatic hernia.

BACKGROUND: There is considerable debate regarding the optimal management of congenital diaphragmatic hernia (CDH) in high-risk infants (those cases presenting with respiratory distress within 2 hours of birth or those diagnosed prenatally). The aim of this study was to analyze patient outcomes using a new treatment protocol for CDH in a tertiary care non-extracorporeal membrane oxygenation (ECMO) neonatal unit. METHODS: The records of 78 consecutive neonates with CDH presenting to Bambino Gesù Children's Hospital from 1996 to 2001 were analyzed retrospectively. Of these infants, 70 high-risk patients were identified (prenatal diagnosis or respiratory distress requiring intubation and assisted ventilation within 2 hours after birth), regardless of associated anomalies, medical condition on presentation, or degree of pulmonary hypoplasia. A prenatal diagnosis was made in 46 of 70 (66%) patients. Associated lethal malformations were present in 6 of the children (8.5%). The patients were placed in 3 historical groups: group 1, 19 patients from 1996 to 1997, group 2, 22 patients from 1998 to 1999, and group 3, 29 patients from 2000 to 2001. In the first 2 groups, a new protocol was introduced using inhaled nitric oxide (iNO) and high-frequency oxygen ventilation (HFOV). In the third group, gentle ventilation and permissive hypercarbia were also used routinely. Mortality and severe morbidity--defined as O2 requirement at discharge, need for a tracheostomy, neurologic impairment, or bilateral hearing loss-were evaluated when the patients were at 6 months old. Univariate analysis was performed. RESULTS: The 3 groups were comparable with respect to predictive risk factors such as side of hernia, prenatal diagnosis, polyhydramnios, stomach and liver in the thorax, associated lethal malformations, and patch. Overall survival rate significantly increased from 47% (9 of 19) in group 1 and 50% (11 of 22) in group 2 to 90% (26 of 29) in group 3 (P =.02). None of the 19 patients in group 1 had severe morbidity compared with 2 of 22 (9%) patients in group 2 and 2 of 29 (7%) patients in group 3. Hearing loss was observed in 4 patients. Mortality rate and preoperative pneumothorax significantly decreased in group 3 compared with groups 1 and 2 (P =.03 and P =.00, respectively). CONCLUSIONS: (1) The application of new treatment protocol for CDH, using gentle ventilation and permissive hypercarbia, produced a significant increase in survival with concomitant decrease in morbidity. (2) The rate of pneumothorax was significantly decreased by the introduction of permissive hypercarbia and gentle ventilation. (3) As more infants survive CDH without the use of ECMO, severe long-term sequelae of CDH can be recognized in these children.

Antenatal diagnosis of surgically correctable anomalies: effects of repeated consultations on parental anxiety.

OBJECTIVE: To assess whether or not a correlation exists between antenatal consultations and parental anxiety. STUDY DESIGN: In total, 31 couples undergoing prenatal consultation after a diagnosis of a surgically correctable anomaly were asked to fill in a questionnaire (Spielberger State-Trait Anxiety Inventory) measuring anxiety levels (AL) both after the first consultation and at birth. Prenatal counselling was done by a perinatal team including paediatric surgeon, obstetrician, and psychologist. RESULTS: Malformations were: eight diaphragmatic hernias, 10 intestinal atresias, four abdominal masses, nine abdominal wall defects. Each fetus was subsequently followed up at regular intervals from diagnosis to birth. AL at birth were then compared with the number of antenatal consultations. A negative correlation (r=-0.688, p<0.001) was found between the number of consultations and the level of anxiety at birth. Patients having at least two consultations had significantly lower anxiety levels at birth. CONCLUSION: Irrespective of the type of malformation, there is evidence that having more than one antenatal consultation may significantly reduce AL at birth. Therefore, early antenatal diagnosis should be encouraged in order to increase as much as possible chances of repeated consultations for the prospective parents.

[Prenatal diagnosis of congenital diaphragmatic hernia: an update]. / Aggiornamento in tema di diagnosi prenatale di ernia diaframmatica congenita.

Congenital diaphragmatic hernia (CDH) has an incidence of approximately 1:4000 live births. Most frequently the diaphragmatic defect is a left and posterolateral (Bochdalek) one. Prenatal diagnosis is made at ultrasonography; the relevant sonographic features will be described in the paper. Cystic adenomatoid malformation of the lung (CAML), pulmonary sequestration, bronchogenic cysts, pulmonary hypoplasia/agenesia need to be considered in differential diagnosis. In some cases, diagnosis of CDH is not possible "in utero": in such cases, herniation of abdominal viscera into the thorax takes place presumably just at delivery through a small diaphragmatic defect. CDH may be associated with intrauterine growth retardation (IUGR), chromosomal abnormalities (3%) and/or other malformations (10-50%): such as Central Nervous System, digestive, cardiac and urogenital anomalies. Therefore, search of associated malformations and amniocentesis with analysis of fetal karyotype are mandatory, whenever a CDH is diagnosed. CDH is still at present characterised by a high mortality (reportedly, about 45%). Many prognostic factors have been correlated to postnatal outcome of CDH: some of them are valuable prenatally by ultrasonography. However, the role of sonography in the prediction of neonatal outcome is still controversial: in particular, although many ultrasonographic parameters have been proposed, prenatal evaluation of pulmonary hypoplasia (a crucial factor related to postnatal survival) has not proved to be very accurate so far. Nevertheless, it is undisputable that prenatal diagnosis itself represents a crucial prognostic factor for CDH, since it allows birth of the affected fetuses in 3d level Perinatologic Centres provided with a Neonatal Intensive Care Unit and Neonatal Surgery.

The impact of cystic fibrosis on neonatal intestinal obstruction: the need for prenatal/neonatal screening.

To determine the incidence of cystic fibrosis (CF) in neonates with intestinal obstruction (NIO) secondary to meconium ileus (MI), jejunoileal atresia (JA), meconium plug syndrome (MPS), volvulus (V), and meconium peritonitis (MP) and analyze the correlation of ultrasonographic (US) signs with CF in NIO with a prenatal diagnosis of intestinal anomaly, a prospective analysis of different types of NIO from 1990 to 1998 was undertaken. Immunoreactive trypsin measurement, genetic studies, and sweat tests were performed to confirm or rule out CF. Cases with prenatal diagnosis were analyzed for gestational age, dilated bowel, ascites, hyperechoic bowel, and calcifications. Of 80 neonates, 19 (24%) had CF: 2/33 (6%) JA, 6/14 (43%) MPS, 1/14 (7.1%) MP, 10/10 (100%) MI, and 0/9 V. Thirty (37.5%) had a prenatal diagnosis of an intestinal anomaly. The overall incidence of CF in NIO with a prenatal diagnosis of intestinal anomaly was 4/30 (13%), or 333 times the estimated risk of CF in the general population. A hyperechoic pattern with dilated bowel was associated with higher specificity for CF: 3/3 cases (100%), followed by hyperechoic bowel with ascites: 3/4 cases (75%). All babies with any type of NIO should thus be screened for CF. Prenatal screening for CF should be indicated in all pregnancies with US patterns of specific intestinal disorders.

Bipedicled skin flaps for reconstruction of the abdominal wall in newborn omphalocele.

Despite technical refinements in surgery and advances in postoperative intensive care, abdominal wall closure in giant omphalocele remains a difficult endeavor. In this respect, bipedicled skin flaps obtained with longitudinal incisions along the margins of the rectus abdominis muscle may represent a good alternative solution to achieve a complete, tension-free midline closure. Incisional areas can subsequently be easily covered with split-thickness thigh grafts. Two neonatal cases were treated with this technique with good results. This has enabled avoidance of palliative coverage as well as complex musculo-cutaneous reconstructions at a later age.

Exteriorization-aspiration minilaparotomy for treatment of neonatal ovarian cysts.

INTRODUCTION: Recent literature indicates that laparoscopic techniques are considered the most appropriate approach for management of neonatal ovarian cysts (NOC). However, laparoscopic equipment may be unavailable in most centers, has high costs, and demands a long learning curve, especially in newborns. METHODS: A minilaparotomy with exteriorization-aspiration ("catch and suck") approach was used in 14 female newborns with antenatally diagnosed ovarian cysts. Average operating time was 25 minutes (range 15-45 min.). Postoperative course was uneventful in all cases; no intra- or postoperative complications were recorded. Length of stay was 48 hours in all patients. CONCLUSIONS: Minilaparotomy with cyst aspiration and subsequent removal may prove a reliable and safe technique in the treatment of NOC: operating time and length of stay are not significantly longer than laparoscopic approach, making this procedure a valid alternative.

Digital fluorographic video-urodynamics in the long-term morphofunctional evaluation of Alcini's Ileocecourethrostomy and ileal reservoir.

INTRODUCTION: The authors present the functional long-term follow-up by means of digital fluorographic video-urodynamics (DFVUDM) of two different surgical urinary diversions. MATERIALS AND METHODS: 64 of 101 patients submitted to radical cystectomy from 1983 to 1999 for infiltrating bladder cancer, were diverted by means of an Alcini's ileocecourethrostomy (ICUS+T), and the remaining 37 patients by means of an ileal reservoir (IR). All of those orthotopically diverted patients were submitted to an accurate follow-up which included DFVUDM 1, 3, 6, and 9 years after the surgical procedure (mean follow-up 51 +/- 42 months). RESULTS: All the evaluated patients showed a neobladder with good function during both the filling and the voiding phases. In 88.8% of the DFVUDM examinations, it was possible to find a residual peristaltic activity of the neobladder walls. Such a residual peristaltic activity caused urinary leakage during the examination in 11.1% of cases, while vesico-ureteral reflux was detected in 12.5%. The patients voided by relaxing the perineal floor and/or by contracting the abdominal muscles: the emptying of the reservoir was often excellent with average residual urine of 28.5 ml. None of the patients needed clean intermittent catheterization. EMG evaluation of the pelvic floor in some of patients showed a peculiar EMG pattern characterized by an insufficient voluntary control of the perineal musculature with a slight increase of EMG activity during bladder filling. Moreover, an insufficient relaxation of the pelvic floor muscles in the beginning of and during the micturition has been seen. This particular EMG pattern was present in 22.22% of all patients included in this study while it was particularly high (81.81%) in patients with leakage. CONCLUSION: DFVUDM evaluation represents a highly sophisticated tool which allows an accurate long-term morphofunctional evaluation of the urinary diverted patients. In this study, it is shown that the functional results of the two studied surgical procedures, namely Alcini's ICUS+T and IR, are quite similar, demonstrating that the taeniotomies on the cecal tract may have almost the same functional effects of detubularization. Although DFVUDM revealed imperfect functional performances in some patients, the quality of life of diverted patients in our series seems to be satisfactory.

Cystic anomalies of biliary tree in the fetus: is it possible to make a more specific prenatal diagnosis?

BACKGROUND/PURPOSE: Biliary tree cystic malformations (BCM) occur rarely. Current progress in ultrasonography makes it possible to identify them prenatally. The aim of this study was to analyze retrospectively prenatal ultrasound patterns of 5 consecutive subhepatic cysts in an effort to differentiate the BCM before birth and onset of symptoms. METHODS: The prenatal ultrasound patterns of 5 consecutive BCM were correlated with the postnatal diagnosis. RESULTS: Case 1 showed a hyperechogenic cyst that underwent enlargement during fetal life; the diagnosis at birth was an obstructed choledochal cyst (CC). In cases 2 and 3, an anechoic cyst with small, stable dimensions during pregnancy was identified; a biliary atresia (BA) type III-C was confirmed at birth. A slightly hyperechogenic cyst with no increase in size at repeated prenatal scans, was observed in cases 4 and 5; a CC and a cystic lesion at the confluence of the hepatic ducts (without obstruction) were diagnosed postnatally, respectively. CONCLUSIONS: The ultrasound scan pattern and size allow to make a prenatal differential diagnosis of BCM. Anechoic, small cyst in the hepatic hilum is highly suspicious for BA. Large, echoic or enlarging cyst is strongly suggestive of "obstructed" CC. Echoic, small and stable cyst is more suggestive of "unobstructed" CC.

Multidisciplinary management of fetal surgical anomalies: the impact on maternal anxiety.

AIM: To assess the impact on maternal anxiety of a multidisciplinary approach in prenatal management of fetal surgical anomalies. DESIGN: A case-control study was undertaken: Group A (cases) consisted of 16 couples receiving a prenatal multidisciplinary counselling, Group B (controls) was represented by 16 couples, who received diagnosis of the fetal anomaly and the relevant counselling by an obstetrician only. The fetuses were affected by the following gastrointestinal anomalies: gastroschisis, omphalocele, intestinal atresia. METHODS: The Italian version of the Spielberger State-Trait Anxiety Inventory was utilized to assess maternal anxiety. In Group A maternal anxiety level was assessed after the first antenatal counselling and at birth, whereas in Group B only at birth. RESULTS: At birth, Group A presented STAI-S scores significantly lower than after the first antenatal consultation with the team (Mean +/- SD = 39.87 +/- 6.46 versus 68.93 +/- 5.81; p < 0.01). At the end of the first day spent with the baby in the Neonatal Surgery Unit, Group A presented STAI-S scores significantly lower than Group B (Mean +/- SD = 39.87 +/- 6.46 versus 70.62 +/- 4.12; p < 0.01). CONCLUSIONS: This study provides evidence of the positive impact on maternal anxiety of a multidisciplinary approach in prenatal management of fetal surgical anomalies.

Severe congenital diaphragmatic hernia (CDH): a critical analysis of eight years' experience.

UNLABELLED: OBJECTIVES. 1) To define the best outcome of severe Congenital Diaphragmatic Hernia (CDH); 2) to critically evaluate deaths in order to identify possible criteria of exclusion from ECMO; and 3) to identify CDHs which could benefit from ECMO. MATERIALS AND METHODS: 63 severe CDHs, 35 (55.6 %) survivors and 28 (44.4 %) nonsurvivors, subdivided into 2 groups according to age at death: Group I dying at 12 < or = 24 hours, and Group II dying at > 24 hours after birth. The three groups were compared on the basis of prenatal diagnosis, polyhydramnios, gestational age, birth weight, pneumothorax, best values of postductal PaCO 2 and PaO 2, clinical and echocardiographic signs of persistent pulmonary hypertension, and severity of pulmonary hypoplasia (i.e., body weight to bilateral lung weight ratio at autopsy). RESULTS: PaCO 2, PaO 2 and degree of pulmonary hypoplasia were significantly worse in Group I compared to Group II and to survivors. PaCO 2 and PaO 2 in Group II did not differ significantly from those of survivors. CONCLUSIONS: In severe CDH it is possible: 1) to achieve a survival rate of 56 % without ECMO; 2) to identify a group of patients (Group I = 27 %) with severe pulmonary hypoplasia who would probably die even with ECMO; and 3) to identify a group of patients (Group II = 17 %) who might benefit from ECMO treatment.

Prenatal diagnosis of a bronchogenic cyst in an unusual site.

We report a rare case of a subdiaphragmatic cyst, diagnosed prenatally during routine ultrasound screening at 25 weeks' gestation. Serial ultrasonographic evaluation demonstrated a slight increase in the size of the cyst during pregnancy. On the basis of the anatomic site and the sonographic features of the lesion, four diagnostic hypotheses were postulated: cystic neuroblastoma, adrenal hemorrhage, duplication of the inferior third of the esophagus and retroperitoneal cystic lymphangioma. A healthy baby, weighing 3300 g and with Apgar scores of 8 and 9, was delivered vaginally at term. He underwent successful surgery at the age of 3 months. The post-operative course was uneventful and the baby is currently doing well. Histology revealed a bronchogenic cyst.

Cystic adenomatoid malformation of the lung: clinical evolution and management.

UNLABELLED: Cystic adenomatoid malformation of the lung (CAML) is a rare pulmonary maldevelopment resulting from an abnormal growth of the terminal bronchial structures. This study proposes a possible management of prenatally diagnosed CAML. A group of nine cases of CAML diagnosed prenatally between January 1990 and December 1995 was studied retrospectively. The evolution of lesions was followed in utero by serial ultrasound monitoring. Chest X-ray was performed at birth in all neonates and CT only in the symptomatic ones. CAML was macrocystic in three cases and microcystic in six. No polyhydramnios, hydrops or associated malformations were seen. In four cases, CAML was confirmed at birth and required surgery. The lesion decreased in size prenatally in five fetuses, of whom only one underwent surgery. In two further cases a prenatal diagnosis of CAML was changed to diaphragmatic hernia. CONCLUSION: Given the possible clinical disappearance or resolution of cystic adenomatoid malformation of the lung, we believe that surgery is justified at birth only in symptomatic and radiologically positive neonates. It could be safely delayed in those asymptomatic patients with either positive or negative chest X-ray. The former need computed tomography at birth, whereas, in the latter, it should be performed at 6 months of age for a more definitive assessment of the patient.
