Subdural hematoma in infants: can it occur spontaneously? Data from a prospective series and critical review of the literature

Subdural hematomas (SDH) in infants often result from nonaccidental head injury (NAHI), which is diagnosed based on the absence of history of trauma and the presence of associated lesions. When these are lacking, the possibility of spontaneous SDH in infant (SSDHI) is raised, but this entity is hotly debated; in particular, the lack of positive diagnostic criteria has hampered its recognition. The role of arachnoidomegaly, idiopathic macrocephaly, and dehydration in the pathogenesis of SSDHI is also much discussed. We decided to analyze apparent cases of SSDHI from our prospective databank. We selected cases of SDH in infants without systemic disease, history of trauma, and suspicion of NAHI. All cases had fundoscopy and were evaluated for possible NAHI. Head growth curves were reconstructed in order to differentiate idiopathic from symptomatic macrocrania. Sixteen patients, 14 males and two females, were diagnosed with SSDHI. Twelve patients had idiopathic macrocrania, seven of these being previously diagnosed with arachnoidomegaly on imaging. Five had risk factors for dehydration, including two with severe enteritis. Two patients had mild or moderate retinal hemorrhage, considered not indicative of NAHI. Thirteen patients underwent cerebrospinal fluid drainage. The outcome was favorable in almost all cases; one child has sequels, which were attributable to obstetrical difficulties. SSDHI exists but is rare and cannot be diagnosed unless NAHI has been questioned thoroughly. The absence of traumatic features is not sufficient, and positive elements like macrocrania, arachnoidomegaly, or severe dehydration are necessary for the diagnosis of SSDHI.

Inflammatory Myelopathies and Traumatic Spinal Cord Lesions: Comparison of Functional and Neurological Outcomes

Outcomes knowledge is essential to answer patients' questions regarding function, to plan the use of resources, and to evaluate treatments to enhance recovery. The purpose of this study was to compare the outcomes of patients with traumatic spinal cord injury (SCI) with those of patients with inflammatory spinal cord lesions (ISCLs). The authors evaluated 181 subjects with traumatic SCI and 67 subjects with ISCLs. Using a matching cohorts procedure, 38 subjects were selected from each group. The measures used were the American Spinal Injury Association (ASIA) Impairment Scale (motor function), the Barthel Index (BI), the Rivermead Mobility Index (RMI), and the Walking Index for Spinal Cord Injury (WISCI). The subjects in the ISCL group were older than those in the SCI group, with a longer interval from onset of lesion to rehabilitation admission and more incomplete lesions. In the matching cohorts, at admission, the traumatic SCI group had RMI and WISCI scores comparable to those of the ISCL group, but the traumatic SCI group had lower scores on the BI (greater dependence on assistance for activities of daily living). At discharge, the 2 groups had comparable functional outcomes. The neurological status of the 2 groups was comparable at admission and discharge. The results indicate that, at admission, patients with SCI have a greater physical dependence for assistance with activities of daily living than patients with ISCLs who have comparable neurological status. Such a difference depends on factors not related to the spinal cord lesion, such as the presence of associated lesions, the need to wear an orthotic device, or the sequelae of surgery. The outcomes of patients with SCI are determined more by factors such as lesion level and severity and age than by etiology. This finding could have implications for health care planning and rehabilitation research.

Arthroscopic Management of Superior Labral Anterior and Posterior (SLAP) and Associated Lesions: Clinical Features and Functional Outcome

The superior labral anterior and posterior (SLAP) lesion is a cause of chronic shoulder pain and significant disability. This study aims to review the distribution of types of SLAP lesions, associated lesions and the outcome of arthroscopic management. This series involved all 33 patients who underwent arthroscopic management of SLAP and associated lesions by a single surgeon. The pre- and postoperative disability scores were assessed using the disabilities of the arm, shoulder and hand (DASH) outcome measure. Type 2 SLAP lesion (64%) was the most common. Forty-eight per cent of the cases were associated with an ipsilateral shoulder lesion. A 10- point pre- and postoperative DASH score reduction was noted in 63% of the patients with isolated SLAP lesions and 73% of those with associated lesions. Arthroscopic management of the SLAP and its associated lesions results in improved functional outcome. The presence of associated lesions should be actively sought and managed in the same operative session.

In congenitally corrected transposition of the great arteries 10-years-mortality is not determined by the type of operation

Objective: The surgical concepts for patients with congenitally corrected transposition of the great arteries (CCTGA) include biventricular repair with or without correcting discordant connections or univentricular palliation. Presence of associated lesions, such as ventricular septal defect (VSD), pulmonary stenosis (PS), tricuspid insufficiency (TI), or functionally single ventricle (SV) need to be taken into account.

Antenatal Post-hemorrhagic Ventriculomegaly: A Prospective Follow-up Study

The aim of this study was to evaluate the presence and the severity of neurological and cognitive impairment at 2 years of age in 16 infants (9 term born, 7 preterm of mean gestation 33.6 weeks) with cerebral ventriculomegaly of antenatal onset associated with intraventricular haemorrhage. Ventricular dilatation, with or without associated lesions, was, with one exception, not identified on the antenatal routine scan at approximately 22 weeks but was obvious on the scans performed between weeks 27 and 33. In 8 of the 16 cases there were signs of parenchymal involvement or of abnormalities of the corpus callosum or cerebellum. In all patients the diagnosis of antenatal IVH was confirmed by early neonatal imaging. Outcome was measured using the Hammersmith infant neurological examination and the Griffiths developmental scales at 2 years. At 2 years, 8 infants had normal motor outcome and 8 had cerebral palsy. The presence and severity of cerebral palsy or neurodevelopmental delay was not always related to the magnitude or symmetry of the ventricular dilatation per se. The presence of associated lesions was a negative prognostic marker. The early development of epilepsy was also associated with an abnormal outcome.

Penile lesion from gunshot wound: a 43-case experience

To demonstrate the main aspects of diagnosis, treatment and follow-up of 43 patients with gunshot wounds to the penis. The location of the lesion, the presence of associated lesions, the performance of complementary exams, surgical treatment, postoperative complications and long term follow-up of 43 patients with penile lesions from gunshot wounds were retrospectively analyzed. Of 43 cases assessed, 41 were submitted to surgical exploration (95.3%) and 2 were submitted to conservative treatment (4.7%). We found penile lesions involving the corpus cavernosum in 37 cases; the remaining 4 patients presented no lesions involving the corpus cavernosum, urethra or testicles but did in the superficial structures. Ten cases presented an association with testicular lesions and 14 cases association with anterior urethral lesions. Penile lesions from gunshot wounds should be treated with immediate surgical intervention. In exceptional situations featuring superficial lesions only conservative treatment may be applied.

Spontaneous echo contrast of unexpected etiology

Cor triatriatum sinister is a rare congenital anomaly characterized by the presence of a fibromuscular membrane dividing the left atrium into two chambers: one entering the four pulmonary veins, the other connecting to the mitral valve. The extent of the communication between the two chambers and the presence of associated lesions determine the severity of symptoms and the complications. We report the case of a 20-year-old man firstly diagnosed with obstructive cor triatriatum sinister and severe pulmonary hypertension.

Chronic paroxysmal hemicrania, hemicrania continua and SUNCT syndrome in association with other pathologies: a review.

We present a review of 22 cases of headache mimicking chronic paroxysmal hemicrania (CPH) (17 female and five male; F : M ratio 3.4), nine cases mimicking hemicrania continua (HC) (seven female and two male) and seven cases mimicking SUNCT syndrome (five male and two female) found in association with other pathologies published from 1980 up to the present. All case reports were discussed with respect to diagnostic criteria proposed by International Headache Society (IHS) for CPH, by Goadsby and Lipton for HC and SUNCT, and evaluated to identify a possible causal relationship between the pathology and the onset of headache. The aim of the present review was to evaluate if the presence of associated lesions and their location could help elucidate the pathogenesis of trigeminal autonomic cephalalgias (TACs).

The clinical profile of Ebstein's malformation as seen from the fetus to the adult in 52 patients.

Ebstein's malformation of the tricuspid valve is a rare but complex congenital cardiac lesion characterised by a variable degree of dysplasia and displacement of the proximal attachments of its inferior and septal leaflets from the true atrioventricular junction. The aim of our retrospective study is to report the risk factors for mortality, and to determine the clinical profile as seen in 52 cases diagnosed in our service between 1978 and 2002, concentrating in particular on the outcome for the neonatal patient. There were 26 females and 26 males, and the age at presentation ranged from 30 weeks gestational age to 46 years. We found 23 associated cardiac anomalies in 20 cases. Of the patients, 11 patients (21%) died. Actuarial survival at 30 years was 65%. Predictors of death included fetal or neonatal presentation, presence of associated defects, a grade within the Celermajer index of 3 or 4, and a cardiothoracic ratio equal to or greater than 65%. The diagnosis was made in the neonatal period in 24 patients, nine of whom died. Of the 15 survivors, only 4 are free of symptoms. Surgical treatment was undertaken in 9 patients, with a mortality rate of 33% without late deaths, with all the survivors being in good condition. The mean period of follow-up for the 41 living patients was 16.5 years. An arrhythmia of variable severity appeared during the evolution of 27 patients (66%). At present, only 7 cases are in the functional class III or IV of the grading system of the New York Heart Association, but 25 patients (61%) needed some medical treatment, meanly for arrhythmic events. Thus, fetal and neonatal presentation of Ebstein's malformation is associated with a poor outcome. Moreover, the echocardiographic appearance, marked cardiomegaly, and the presence of associated lesions are all risk factors for mortality. Arrhythmia and need of medical treatment are common in older children and adults. Survival after surgical treatment is associated with a good outcome.

Telangiectatic focal nodular hyperplasia: US, CT, and MR imaging findings with histopathologic correlation in 13 cases.

To review the ultrasonographic (US), computed tomographic (CT), and magnetic resonance (MR) imaging findings in 13 patients with telangiectatic focal nodular hyperplasia (FNH) and to compare imaging features with histopathologic results from resected specimens. US, helical multiphasic CT, and MR images in 13 patients with pathologically proven telangiectatic FNH were reviewed retrospectively. Two abdominal radiologists evaluated lesions for number, size, heterogeneity, surface characteristics, presence of a central scar, presence of a pseudocapsule, US appearance, attenuation at CT, signal intensity at MR imaging, and presence of associated lesions. Imaging and pathologic findings were compared. Sixty-one lesions (5-140 mm in diameter) were seen at imaging. Lesions were multiple in eight of 13 (62%) patients. Imaging characteristics were heterogeneity in 26 of 61 lesions (43%), well-defined margins in 43 of 61 (70%), lack of a central scar in 56 of 61 (92%), presence of a pseudocapsule in three of 61 (5%), hyperintensity on T1-weighted MR images in 17 of 32 (53%), strong hyperintensity on T2-weighted MR images in 24 of 54 (44%), and persistent enhancement on delayed contrast material-enhanced CT or T1-weighted MR images in 23 of 38 (61%). No specific US pattern was noted. Two patients had additional lesions: One had classic FNH, and the other had a cavernous hemangioma. Hyperintensity on T1-weighted MR images was due to sinusoidal dilatation. Hyperintensity on T2-weighted MR images correlated well with the presence of inflammation. Telangiectatic FNH differs from typical FNH at imaging: Atypical FNH features often observed with telangiectatic FNH are lack of a central scar, lesion heterogeneity, hyperintensity on T1-weighted MR images, strong hyperintensity on T2-weighted MR images, and persistent contrast enhancement on delayed contrast-enhanced CT or T1-weighted MR images.

Classification of traumatic hip dislocation.

The commonly used classification systems of hip dislocation are based on the direction of the dislocation and the presence of associated lesions. However, no rating system can reliably predict the patient's outcome and prognosis based on the initial presentation and classification. In general, patients with anterior dislocations have the best prognosis. Other factors affecting the prognosis are the associated injuries and more importantly the delay between dislocation and reduction.

Complications of operative treatment of injuries of peripheral arteries

In 1991 and 1992, a total of 97 patients with 106 peripherial arterial injuries underwent surgery at the Institute for Cardiovascular Diseases, Clinical Centre of Serbia. Civilian injuries accounted for 53 (54.6%) patients (94.3% males, age range: 16–63 yr, mean: 35.2), and 44 patients had war injuries (93.2% males, age range: 19–61 yr, mean: 34.8). The injuries affected the superfitial femoral artery in 31 (29.24%); the popliteal artery in 28 (26.41%); the brachial artery in 17 (16.04%); the posterior tibial artery in 6 (5.66%); the axillary artery in 5 (4.72%); the anterior tibial artery in 5 (4.72%); the tibioperoneal trunk in 4 (3.77%); the common femoral artery in 4 (3.77%); the external iliac artery in 2 (1.89%); the profound femoral artery in 2 (1.89%); the radial artery in 1 (0.94%); and ulnar artery in 1 (0.94%). A total of 98 reconstructive procedures were used to treat these patients. Graft interposition carried out in 50 (51.02%); by pass in 25 (25.51%); end-to-end anastomosis in 9 (9.18%); suture in 8 (8.16%); ligation in 4 (4.08%); and patch-angioplasty in 2 (2.04%). Primary reconstruction of injured arteries was performed in 72.2% and secondary repair in 27.8% cases. Infection developed in 51 (52.57%) patients, and it was significantly ( P<0.05) more common in the war injuries (70.45%) and in secondary repairs (88.89%). The presence of associated lesions (69.56%) was also correlated with a greater rate of infection. Amputation was necessary in 21 (21.65%) of our patients, and was significantly ( P<0.05) more often performed after secondary (44.44%) than primary operations (12.86%) and in the presence of associated injuries (32.61%).

CT prognostic factors in acute subdural haematomas: the value of the 'worst' CT scan

The relationship between radiological findings and outcome in patients with acute posttraumatic subdural haematomas (SDH) has been based on CT obtained upon hospital admission. This study was undertaken to investigate the effects on prognosis of SDH patients of lesions not present on admission, but detected by subsequent CT.We have also studied those findings present on admission CT that could predict worsening of the associated lesions. From 1 May 1989 to 30 April 1996, we admitted 206 patients harbouring acute SDH of thickness 5 mm or more. The admission GCS score ranged from 3 to 15. Each patient underwent CT on admission (always within 3 h from injury). Follow-up CT was performed within 12-24 h after injury and in the following days (an average of 4.3 examinations for each patient). These examinations were reviewed by a neuroradiologist and the 'worst' CT was determined. We defined the 'worst' examination as that showing the largest haematoma thickness/midline shift and/or with the most extensive degree of parenchymal damage. Clinical factors related to prognosis in this series are age, hypoxia/hypotension, GCS motor score and pupillary abnormalities. Time from injury to treatment was found relevant only in patients with isolated SDH. CT findings on admission that correlated with outcome were haematoma thickness, midline shift and status of the basal cisterns. Prognosis was also worsened by the presence of associated lesions; SAH alone or associated with brain contusions. The last of these was the single most powerful predictor of worse outcomes (Odds ratio 0.37, p <0.004).Whereas the first CT showed parenchymal associated damage in 56 patients, the 'worst CT' showed such damage in 105 patients. Presence of SAH on admission was found significant (p <0.02) in predicting evolving parenchymal damage. Haematoma thickness, midline shift, status of the basal cisterns and presence of SAH are related to outcome when identified on the initial (early) CT examination. However, early (within 3 h from injury) CT under-estimates the ultimate size of parenchymal contusions. Patients with SAH on early CT are those at highest risk for associated evolving contusions. The use of sequential CT should be included in the routine management of head-injured patients.

Ebstein's anomaly: Presentation and outcome from fetus to adult

Objectives. This study was conducted to investigate the presentation and outcome of ptients with Ebstein's anomaly of the tricuspid valve.Background. Ebstein's anomaly may present at any age and has a highly variable clinical course. Previous natural history studies have been on clinical and angiographic diagnosis and have included mainly older children and adults. Echocardiography, however, has facilitated fetal and neonatal diagnosis so that the natural history needs to be redefined.Methods. We reviewed 220 cases of Ebstein's anomaly presenting from fetal to adult life between 1958 and 1991, with 1 to 34 years of follow-up.Results. The most common presentation in each age group was abnormal routine prenatal scan for fetuses (86%), cyanosis for neonates (74%), heart failure for infants (43%), incidental murmur for children (63%) and arrhythmia for adolescents and adults (42%). Early presentation was frequently associated with other cardiac lesions, usually pulmonary stenosis or atresia. Surgery was undertaken at some stage in 86 (39%) of the 220 patients. Actuarial survival for all liveborn was 67% at 1 year and 59% at 10 years. There were 58 deaths, including 26 from heart failure, 19 perioperative and 8 sudden. Predictors of death included echocardiographic grade of severity at presentation (relative risk 2.7 for in grade, 95% confidence limits 1.6 to 4.6), fetal (6.9, confidence limits 1.6 to 16.5) and right ventricular outflow tract obstruction (2.1, confidence limits 1.1 to 4.4). Morbidity was mainly related to arrhythmias and late hemodynamic deterioration. Of 155 survivors, 129 (83%) were in functional class 1 and 104 (67%) were receiving no medical therapy.Conclusions. In Ebstein's anomaly, fetal and presentation is associated with a poor outcome and can be predicted by the echocardiographic appearance and presence of associated lesions. In older children and adults, incidental findings and arrhythmia are common and the long-term outcome is superior.

Gunpowder-related burns

Gunpowder misuse is a frequent cause of burn injury in our area. The injuries are mostly minor lesions which may be treated on an outpatient basis, the more serious injuries need surgical treatment. Experience of the management of these burns is reported by reviewing 123 clinical charts of patients admitted between 1983 and 1990. The most frequent victims are teenage males who are involved mainly in accidents in the street. The most serious burns followed work-related accidents, with a fatal outcome in 47 per cent of the patients. The serious burns are usually deep dermal or full skin thickness. A common pattern affects groins, genitalia, hypogastrium and hands, and are produced when fireworks ignite in the pockets of the patient's trousers. The management of these lesions does not differ from burns caused by other agents, although attention should be paid to the presence of associated lesions, chiefly to eyes, ears and hands, due to the shockwave and shrapnel.

Intraoperative echocardiography in mitral and tricuspid valve repair.

Echocardiography with Doppler color flow mapping is a very useful intraoperative technique in patients undergoing mitral or tricuspid valve repair. In the patient who is a repair candidate, this technique can be used intraoperatively to answer important clinical questions: the severity of the regurgitation; the morphological basis of the regurgitant lesion; and the feasibility of repair. Other important issues such as the impact of physiological interventions on regurgitation severity, the presence of associated lesions, and the state of ventricular function can also be addressed. In the patient who has undergone a valve repair, this technique can be used intraoperatively prior to chest closure to assess the adequacy of the repair procedure and to detect associated complications such as outflow tract obstruction.

Urethral Trauma

Experience with treatment of 38 patients in an early phase with urethral trauma is presented. The site of injury was the penile urethra in three cases, the bulbous urethra in seven, and the prostatomembranous urethra in 28. Different surgical procedures were used, according to the site and the extent of urethral damage and the presence of associated lesions. All patients with penile and bulbous urethral trauma were cured and only one has diminished sexual potency, while in the posterior urethral group nine were cured, and 19 developed strictures requiring further surgical treatment. Total impotence developed in 17 and partial impotence in one patient. Another case presents urinary urge incontinence.

Observations Concerning Radial Neck Fractures in Children

Twenty-three children with fractures of the radial neck were reviewed. Fractures with an angulation of greater than 60 degrees were treated by open reduction and internal fixation with transarticular Kirschner wires through the humerus and the radius. These broke at the joint in two patients, and we now avoid the humerus by using oblique Kirschner wires. Some limitation of movement, especially of forearm rotation, was more common in children with associated lesions of the same elbow and with open reduction. We think that this reflects the severity of the injury rather than the presence of associated lesions or the surgery itself.
