Prevalence of impairments 5 years after a head injury, and their relationship with disabilities and outcome

To determine what consequences cognitive, behavioural or somatic impairments had on disabilities and recovery after a head injury (HI), a population-based sample of 231 adult patients was studied 5 years after an HI. Eighty lower-limb-injured (LLI) patients were considered as controls. Sixty-four LLI and 176 HI patients were reviewed (114 minor, 35 moderate, and 27 severe HI). Prevalence values of headaches (44-54%), dizziness (26-37%), and anxiety (47-63%) were not significantly different in the three HI severity groups, but were significantly lower in patients with an isolated limb injury (12-15%). Memory problems and depressive mood increased with injury severity. Mental impairments were frequent in severe HI patients (18-40% of patients). In minor and moderate HI patients, most disabilities were related to associated injuries. According to the Glasgow Outcome Scale (GOS), recovery was not considered as good because of somatic, behavioural or cognitive complaints in 2.5%, 5.7% and 59.2% of surviving patients in each of the above HI groups. Somatic or behavioural complaints may have considerable consequences in some minor HI patients, and the long-term management of certain patients needs improvement because these impairments are misunderstood.     

Computerized tomography and prognosis in paediatric head injury

The authors have analysed the computerized tomography (CT) findings and their correlation with the clinical state, early and late outcome in children and adolescents with head injuries (HI). This study represents clinical and CT data of 82 consecutive HI patients under 18 years of age. Among them 51 (62%) were boys and 31 (38%) girls. The application of CT to the evaluation of the morphologic manifestations of HI in children has shown some differences in forms and mechanisms of injury and in outcome compared to adults. In the paediatric HI the most frequent finding was diffuse brain swelling with CT evidence of ventricular and cisternal compression or obliteration. Prognostically the most unfavourable findings were shearing injury, intracerebral and subdural haematomas combined with brain swelling and parenchymal damage. According to the Lidcombe impairment scale, outcome from severe paediatric HI was determined in the 3rd and 6th months, one year and 2 years after the injury. The outcome two years after severe HI varied to a great extent and was better in children than in adults. Although there was long-term disruption of the patient's quality of life, our data show that as there are no predictors of individual outcomes in child HI, no child should be excluded from early and long-term rehabilitation.     

The defective nature of hepatitis delta virus

Forty-nine out of 66 patients with Turner's syndrome and different karyotypes underwent full cardiological evaluations (physical examination, electrocardiography, chest X-ray and echocardiography). Congenital cardiovascular anomalies were found in 11 patients (22.4%). Among the cardiac anomalies in patients with Turner's syndrome, aortic malformations (aortic coarctation [27%], aortic stenosis [18%] and bicuspid aortic valve [18%]) were the most frequent. We observed that the most severe malformations were found in those with karyotype 45,X or 45,X/46,XX. No anomalies were detected in patients with the X isochromosome or those mosaic with the Y component.     

The efficacy of Augmentin in suppurative complications in neurosurgery]

The results of clinical and laboratory studies on the use of augmentin in severe purulent complications after neurosurgical operations are presented. The laboratory studies carried out with the use of an automatic system Cobas Bact (Roch) showed that the numbers of the augmentin resistant strains of Staphylococcus and Enterobacteriaceae among the pathogens were 47 and an average of 64.5%, respectively. Gram-negative bacteria resistant to augmentin were 1.5 to 2 times less frequent than those resistant to amoxycillin. Still, they were much more frequent than those resistant to cefotaxime and ceftriaxone. Clinical efficacy of augmentin was studied in treatment of 39 patients with various affections of the brain such as tumors, trauma, vascular malformations and inflammatory processes. The postoperative complications were represented by meningitis, pneumonia, sepsis and their associations. The use of augmentin in the severe intra- and extracranial complications was favourable in 82.1% of the cases.     

Dermatologic complications of HIV infection

Cutaneous disorders occur with great frequency in patients with HIV infection and increase in number and severity as the disease progresses and immune function declines. In addition, the first findings related to HIV infection are often on the skin. Cutaneous infections with herpesviruses may be severe and atypical in their presentations; papillomaviruses and MC are common as well. Bacterial infections may be primary or secondary to other skin diseases; superficial and deep fungal infections are also prevalent. Papulosquamous disorders, including seborrheic dermatitis, psoriasis, and eczema, may be disfiguring and result in secondary complications. Neoplastic disorders, especially Kaposi's sarcoma, demand early diagnosis, to afford the patient maximal treatment options. All physicians must be aware of these cutaneous manifestations to decrease morbidity and improve quality of life in the HIV-infected individual.     

Neuro-interventional treatment of cerebrovascular malformations

Cerebral vascular malformations are relatively rare diseases, however, their clinical impact is high. The group of vascular malformations include arterio-venous malformations of the brain and of the dura mater (AVM and DAVM) and arterial aneurysms. The danger coming from these malformations lies in the ruture with following cerebral stroke. Patients may die directly, or suffer from numerous deficits as hemipegia, loss of vision or speech and several severe cognitive deficits. Early diagnosis and early treatment is most important to avoid such complications and to prevent the patients from permanent invalidisation. A therapeutic alternative with increasing impact is given with the minimal invasive endovascular procedures. Alone, or in combination used with Radiosurgery and Neurosurgery, these techniques enable a most optimal and risk-reduced therapy for the patients.     

Management of recurrent pilocytic astrocytoma with leptomeningeal dissemination in childhood

Neurofibromatoses are genetic disorders of the nervous system that primarily affect the development and growth of neural cell tissues. These disorders produce other abnormalities such as skin changes and bone deformities. Neurofibromatoses occur in both sexes and in all races and ethnic groups. Scientists have classified these disorders as neurofibromatosis type 1 (NF1) and neurofibromatosis type 2 (NF2). Other types of neurofibromatoses may exist, but are not yet identified. Nearly 50% of the cases shows a well definited familiarity for the disease, according to an autosomal dominant transmission, while the other 50% of patients shows a negative history of familiarity, according to a new chromosomal mutation interesting the same autosomal genes of the dominant transmission. Oral localization is more rare showing an incidence ranging from 4 to 7% in most series of different authors. The most frequent involvement site in oral neurofibromatosis is the tongue, followed by the oral mucosa and floor of the mouth; palate and maxillary-mandibular bones are a rare localization of the disease. In the present, the clinical, radiological, histopathological and therapeutical aspects of a clinical case of neurofibromatosis, presenting as mandibular tumor, are examined. The clinical case reported, a 37 year old man, was essentially characterized by a positive family history for the disease, a neurofibroma of the oral mucosa.     

Neurogenic pulmonary edema in fatal and nonfatal head injuries

Impaired pulmonary function is a frequent but poorly understood complication of acute head injury (HI). A potential early contributor to the pulmonary dysfunction seen in HI patients is neurogenic pulmonary edema (NPE). We hypothesized that NPE would occur early after HI and that it would have a continuum of clinical severity depending on the severity of the HI and associated intracranial hypertension. A large autopsy data base and inpatient HI data base were used to search for cases of NPE. Patients in the autopsy data base were stratified according to injury type and whether they died at the scene or within 96 hours of injury. There were significant (p < 0.0001, analysis of variance) elevations in lung weights in patients dying at the scene and within 96 hours from HI, compared with those dying from other noncentral nervous system injuries. No other organs studied showed significant weight increases. The incidence of NPE in isolated HI patients dying at the scene was 32%. In patients with isolated HI dying within 96 hours, the incidence of NPE was 50%. We found an inverse correlation (r = 0.62; p < 0.0014) between the initial cerebral perfusion pressure and the PaO2/FIO2 ratio despite a normal-appearing chest x-ray film. We conclude that NPE occurs frequently in HI patients. The process of edema formation begins early in the clinical course and is isolated to the lung.(ABSTRACT TRUNCATED AT 250 WORDS)     

Non-invasive detection of ongoing neuronal population activity in normal human hippocampus

In a prospective series of symptomatic adult hydrocephalus characterized by gait disturbance, cognitive impairment, and/or urinary incontinence, 88 of 118 patients (75%) had additional akinetic, tremulous, hypertonic, or hyperkinetic movement disorders. Their prevalence was highest in patients with idiopathic normal pressure hydrocephalus (NPH) of the elderly (56/65 patients, 86%), and they were less frequent in patients with secondary NPH (10/15, 66%), with nonhydrodynamic atrophic/other hydrocephalus (20/33, 61%), and with obstructive hydrocephalus/aqueductal stenosis (2/5, 40%). Akinetic symptoms were found in 73 of 118 patients (62%), and the most frequent movement disorder was upper extremity bradykinesia (55%). Akinetic, tremulous, hypertonic, and hyperkinetic movement disorders were exclusively secondary to causes not related to hydrocephalus in 24 of 118 patients (20%). The proportion of patients with movement disorders not attributable to only such causes was highest in the idiopathic NPH group (44/65, 68%). Thirteen of 118 patients (11%) presented with a parkinsonian syndrome. There was evidence for coexistent Parkinson's disease in four of these patients. Parkinsonism was found to be secondary to NPH in five patients and was found improved after shunting. Akinetic symptoms in patients with NPH generally responded favorably to CSF diversion, which was evident in 80% of a subset of this group. Various other movement disorders did not show definite improvement. The high prevalence of bradykinesia and other akinetic symptoms in NPH and the beneficial effect of shunting on such symptoms suggest that NPH may cause a more generalized disorder of motor function.     

Physical activity and glycaemic control in children with diabetes mellitus

We report nine case histories of patients admitted to a psychiatric hospital for severe somatic disorders. The somatic disease was either the cause of the psychiatric symptomatology, or it occurred in addition to a well-known psychiatric disorder. For general practitioners and psychiatrists it can be difficult to differentiate between symptoms due to psychiatric disorders and symptoms that indicate somatic disorders. If patients refuse the necessary diagnostic or therapeutic procedures and show behaviour that is not related to good health, there is increased risk for complications and increased morbidity.     

Congenital anomalies reflected in materials of obstetric ward of the Hospital of Internal Affairs in Warsaw during the period 1988-96

A congenital anomaly consists of a departure from the normal anatomic architecture of an organ or system. Malformations can be considered as the result of a developmental arrest of the primordium (incomplete morphogenesis), redundant morphogenesis, or aberrant morphogenesis. Congenital malformations establish more and more percentage of reason of incidence and morbidity in newborn and young children. It is also great family and social problem. The subjects studied were all cases of abnormality identified pre- or postnatally. The commonest system malformations were urogenitally tract, central nervous system, skeleton, craniofacial, heart and skin abnormalities. The most frequent single anomalies were--hypospadias, cleft lip/cleft palate, anomalies of hands and feet, vertebral malformations, meningocele, heart abnormalities and Down syndrome.     

Functional evidence for involvement of multiple putative tumor suppressor genes on the short arm of chromosome 3 in human oral squamous cell carcinogenesis

The authors present their experience at the Centre for the surgical treatment of morbid obesity at Milano University where since 1974, 603 obese patients underwent surgery: 312 jejuno-ileal bypass (JIB), 70 bilio-intestinal bypass (BIB), 102 horizontal gastroplasties (HGP), 44 silastic ring vertical gastroplasties (SRVGP) and 75 adjustable silastic gastric banding (ASGB). Average follow-up for these procedures is 16, 6, 11, 4 years and 24 months respectively. Weight loss is satisfactory in all cases even though the percentages vary in the different procedures. The most serious complications (severe hepatic failure, oxalic interstitial nephritis, persisting malabsorption) occurred in patients submitted to JIB. The best clinical outcome with the lowest complications rate was obtained with BIB compared to other intestinal bypasses. The most frequent complication observed in patients submitted to gastroplasties was incoercible vomiting while the most severe complications were diffuse peritonitis, secondary to gastric perforation, and peripheric neuropathy. Our experience confirms that surgical treatment of morbid obesity refractory to medical therapy is today a safe and effective treatment. BIB has still a role in super-obese young patients (BMI over 50) refusing dietary restriction lifetime. The gastric procedures, especially laparoscopic ASGB, seem to be the best option. The excellent outcome of bariatric surgery can be obtained only in specialized centers where various specialists work together.     

Jejunum perforation following blunt abdominal trauma--a case report

We describe an intestinal perforation in a football player who had been hit with the knee in the abdomen. Perforation of the small bowel, following blunt abdominal trauma, is relatively rare. Its most frequent cause is a deceleration trauma, usually from a traffic accident. Clinical signs are frequently discrete and nonspecific. The most frequent symptom is abdominal pain. Lack of bowel sounds is reported in 64% oft the cases. Enteric lesions should be suspected in the presence of a corresponding history (deceleration trauma) and of other pathologies (fractures of vertebrae and/or pelvis). Sonography and computed tomography are rarely helpful. Delayed perforations have been described, necessitating prolonged observation for 48 to 72 h. after painful abdominal trauma. Repeated examinations are essential to rule out enteric perforation. Initially, less than 50% of the cases show free air, thus limiting the usefulness of thoracic and abdominal radiography. Mortality reaches 30%. This rate is adversely affected by concomitant lesions in other organs and by delay (more than 10 h.) in diagnosis. When laparotomy has been delayed and peritonitis is present, antibiotic treatment should be started immediately during surgical intervention (cephalosporin, aminoglycoside, metronidazole). Postoperative complications include septicaemia, wound infection and, rarely, enterocutaneous fistulae.     

Basic principles of LIFE--autofluorescence bronchoscopy. Results of 194 examinations in comparison with standard procedures for early detection of bronchial carcinoma--overview]

We report on our treatment experience in Germany with anagrelide, a novel platelet lowering agent, in 48 patients (27 females, 21 males) with essential thrombocythaemia. Their age was between 19 and 79 yr when anagrelide therapy was initiated. Sixteen patients were previously untreated, 15 pretreated with hydroxyurea and 17 had multiple pretreatments. Forty-one of the 48 patients had either microvascular, thromboembolic or bleeding complications. About 50% received low dose acetylsalicylic acid as an adjunct. Their platelet count prior to therapy ranged from 850,000/microl to 3,100,000/microl. Eighty-seven per cent of the patients treated with anagrelide were complete hematological responders, while 13% responded only partially or failed to respond. Twelve of our patients (25%) developed short-term (from a few days to a maximum of 4 wk) side effects including headache (most frequent), palpitations, tachycardia or nausea. Eight patients reported long-term (more than 1 month) adverse effects. However, in only 5 of all 48 patients (10%) were these side effects not acceptable so that treatment had to be discontinued. We have now treated patients for up to 7 yr (median maintenance dose 2.5 mg/d). Preliminary evidence suggests that anagrelide mediated platelet count reduction also prevents recurrence of thromboembolic complications. Hence, anagrelide has the potential to become the first-line platelet-lowering treatment in myeloproliferative disorders with high platelet counts.     

Surgical management of pulmonary aspergilloma

Between 1983 and 1996., 79 patients'--operated on for pulmonary aspergilloma--clinical data has been analysed. The patients were comprised of 67 males and 12 females, with a mean age of 49 years (range, 24 to 69). Previous lung disorders were observed in about half of the cases (most frequently tuberculosis), while in the other half aspergilloma was developed on the basis of (sub)-acute infections. The most common symptom was haemoptysis (in 45% of cases). Aspergilloma was diagnosed preoperatively (especially by typical chest x-ray) in 62 patients. In the other cases tb, lung cancer, pyosclerosis were suspected. 67 patients underwent pulmonary resection (50 lobectomies, 12 wedge resections, 5 pneumonectomies), 12 cavities were opened by cavernostomy. The postoperative mortality rate was 10.1%. The most frequent complications were bleeding, prolonged air leak, pleural rest space, empyema, bronchial fistula and wound infection, which were occurred in cases with bigger cavities near chest wall. In most cases with pulmonary aspergilloma surgery remains the only effective treatment. Operation has a lower risk in asymptomatic patients, without chest wall involvement. In several cases cavernostomy might be applied successfully.     

Stenosis of the internal carotid arteries and cardiovascular risk factors in a group of patients aged 65 years and over

BACKGROUND: In the present study, the degree of stenosis of internal carotid arteries and the presence of cardiovascular risk factors are examined. METHODS: Two hundred patients underwent high resolution B-mode echotomography of the carotid arteries; furthermore, the presence of associated cardiovascular risk factors was considered. RESULTS: Small stenosis (< 16%) were reported in 113 (56.5%) patients; moderate stenosis (16-49%) were reported in 58 (29%) patients; severe stenosis (50-79%) were reported in 19 (9.5%) patients; subocclusive stenosis (80-99%) were reported in 2 (1%) patients; occlusions were reported in 8 (4%) patients. One hundred and fifty patients (75%) presented one or more associated cardiovascular risk factors. Hypertension was present in 122 (61%) patients; hypercholesterolemia in 43 (21.5%) patients; diabetes mellitus in 41 (20.5%) patients; 26 (13%) patients were smokers. CONCLUSIONS: According to other studies, stenosis < 50% were the most frequent (85.5%) in the subjects examined. Stenosis > or = 50% were more frequent in males than females. Hypertension was the most frequent associated cardiovascular risk factor; therefore the degree of stenosis increased with the increasing number of cardiovascular risk factors.     

Morphologic findings in fetuses and placentas of late abortion in the 2nd trimester

To investigate possible causes of abortion (and intrauterine foetal death) we reviewed clinical and morphological data of foetuses and placentas morphologically from 830 spontaneous abortions seen during a 12 years period (1978-1989) at the Institute of Pathology, University of Leipzig, and the Pathological Institute of Hoyerswerda. Our review showed that definite and possible causes of foetal death and abortion could be classified as placental, foetal maternal, and clinical. Placental changes, which included infection of the foetal membranes, disturbances of the uteroplacental circulation (abruptio placentae with bleeding) and placental dysmaturity, were the most important causes and accounted for 73.8% of the cases. Foetal causes mainly comprised multiple twin pregnancies and foetal malformations. In 20 cases (2.4%) we found malformations as a cause of foetal death and consecutive abortion. Overall, malformations were found in 7.5% of the cases examined. Maternal and obstetric complications of pregnancy were less frequent. In 16.5% of our cases, the cause of the abortion or intrauterine death remained obscure. However, since 1989, genetic analysis and prenatal diagnostic procedures have improved, bringing a greater knowledge on the spectrum and aetiology of possible developmental disorders in the foetus. This should reduce the number of unexplained abortions.     

Anorectal malformations

The posterior sagittal approach was used to treat 792 patients with anorectal malformations. From these, 387 cases were evaluated 6 months to 13 years later. Voluntary bowel movements were present in 74.3% of the entire series. When distributed by diagnosis, the percentages varied: 100% in patients with rectal atresia and perineal fistula; 93.2% in those with vestibular fistula; 80.9% in those with bulbar fistula; 71.1% in those with cloacas; 66.7% in those with prostatic fistula, and 15.8% in those with bladder-neck fistula. Soiling was present in 57% of all cases. Patients with voluntary bowel movements and no soiling were classified as totally continent; 40.8% of the series belong to this group. Distributed by diagnosis, it varied from 100% in cases with rectal atresia or perineal fistula, 65.9% in those with vestibular fistula, 34% in those with bulbar fistula, 31.6% in those with cloacas, 26.3% in those with prostatic fistula; none of the patients with vaginal fistula or bladder-neck fistula was totally continent. Constipation was detected in 43.1% of all patients, and was more frequent in those with simple defects. Urinary incontinence was found in 19% of patients with cloacas who had a common channel shorter than 3 cm, and in 68.8% of the patients who had longer common channels. Other patients suffered from urinary incontinence only when they had an absent sacrum or other severe bladder or urethral congenital defects. An accurate diagnosis and evaluation of the sacrum allows us to establish, with reasonable accuracy, functional prognosis in most children. Those with functional disorders must be treated properly medically, to improve their quality of life.     

Cardiovascular changes in children with mucopolysaccharide storage diseases and related disorders--clinical and echocardiographic findings in 64 patients

Cardiovascular abnormalities were evaluated in 64 children aged between 1 year 9 months and 25 years with mucopolysaccharidoses (MPS) and related disorders. A heart murmur was heard in 18 patients, but in only 6 was it characteristic for specific valvular lesions. Echocardiography was performed in 63 children. In one girl cardiac lesions were diagnosed on autopsy. In 46 patients (72%), valvular lesions and/or different types of cardiomyopathy were detected. There were no characteristic changes for different types of MPS. In the majority of children in whom dermatan sulphate accumulated, cardiac involvement was the most frequent (88%) and severe. The most common lesion, regardless of MPS type, was thickening of the mitral valve (66%), with regurgitation or stenosis in 28 (44%). Aortic valve thickening was detected in 17 patients (27%), asymmetric septal hypertrophy or hypertrophic cardiomyopathy in 18, congestive cardiomyopathy in 1 and endocardial thickening in 13 patients. Cardiac involvement was less frequent in children with Sanfilippo disease. Two or more echocardiographic examinations were performed in 23 patients. In 19 of them (83%) cardiac changes were more severe during the second examination. One 7-year-old boy with Hunter disease underwent successful mitral valve replacement. CONCLUSIONS; Cardiac involvement is present in most patients with MPS although there are few clinical signs and symptoms. The most common and severe changes are in Hurler, Hunter, Maroteaux-Lamy and I-cell disease, rarely in Sanfilippo disease. Mitral valve deformation is most frequent in all patients. The cardiac lesions are progressive.     

Acute epitrochlear lymphadenitis

Blunt trauma accounted for 1/3 of the 32 patients operated upon for injuries of the large intestine and penetrating wounds for 2/3. Most of the blunt injuries (9/10) were caused by traffic accidents, and more than half of the penetrating ones (12/22) were stab wounds. The transverse colon was most commonly affected, followed by the ascending, descending and sigmoid colon, rectum and mesentery. Perforation of the small intestine was the most frequent associated intra-abdominal injury, occurring in 11 patients (34%). Most patients (22/32) underwent simple suture, 6 patients suture with proximal colostomy, 3 primary resection and one exteriorization, combined in all cases with broad-spectrum antibiotic coverage and drainage of the abdominal cavity. Injuries to the right and transverse colon were managed mainly with simple suture, and those to the left colon and rectum with suture and proximal colostomy. 50% of the patients had complications, most frequently wound infection and intra-abdominal abscess. The patients with simple suture had fewer complications than the others. In the absence of complicating factors injuries to the colon are best managed with simple suture, whereas in the presence of complicating factors and in injuries of the rectum, suture or resection with proximal colostomy, especially in cases of severe tissue destruction, remains the treatment of choice.
