ABSTRACT

PURPOSE: Evaluate complications in correlation with radiological findings after an open Latarjet procedure performed on 140 shoulders with recurrent anterior instability with follow-up from 8 to 174 months. METHODS: Retrospectively, 140 shoulders, diagnosed with recurrent anterior glenohumeral instability, which were surgically treated with the open Latarjet procedure in our hospital, between January 2004 and November 2017, had been analysed. Mean age of operated patients was 29.5 years. One hundred and twenty-three patients were male (88.5%) and 16 were female (11.5%). Average length of follow-up was 110 months. Radiographs and CT scans of 16 patients with complications had been evaluated and correlations between radiological findings and observed complications had been analysed. RESULTS: Complications occurred in 16 shoulders (11%). Rates of individual complications were: 1. persistent pain (9%), 2. limited ROM (7%), 3. recurrent instability (6%), 4. neurologic injury (2%), 5. persistent apprehension (2%), 6. reduced strength (2%), 7. hematoma (1%) and 8. intraoperative coracoid graft fracture (0.8%). Mean postoperative ASES score and ROWE score were statistically significantly lower in the group with complications, compared to the group without complications. Good or excellent results were reported by 87.9% patients. CONCLUSION: Open Latarjet procedure is an effective and safe method for the treatment of recurrent shoulder instability, resulting in good to excellent outcomes in 87.9% of our cases. However, it is related to a higher postoperative complication rate compared to some other treatment options. Overall, very good results with high level of patient satisfaction have been demonstrated.

ABSTRACT

PURPOSE: A new arthroscopic technique with Cobra Guide (CG) was developed to enable fast, controlled and strong intraosseous biceps tenodesis while avoiding an implant. The purpose of this study was to compare the newly developed suture-only biceps tenodesis technique [arthroscopic suprapectoral intraosseous implant-free biceps tenodesis (ASIIBT) with the new CG] to classical interference screws (IS) and suture anchors (SA) in terms of construct resistance to failure. MATERIALS AND METHODS: Fifty-eight human cadaveric shoulders were randomized into three treatment groups. Twenty shoulders received an IS, 19 SA and 19 ASIIBT. A biceps tenodesis was performed according to the techniques listed above. Cyclic loading tests on a dynamic loading testing device were used to measure and compare the resistance to failure pullout between the three groups. Hartley's Fmax test and Tukey's Honest Significant Difference method were used for statistical analysis. RESULTS: The construct with the greatest resistance was ASIIBT. Its resistance was statistically higher compared to the IS technique (p = 0.001). Resistance compared to the SA technique was not statistically significant (p = 0.123), although in seven cases ASIIBT resisted more than 50 cycles at 200 N, while the SA technique reached 50 cycles at 200 N in just two cases. During cyclic loading, each specimen failed at the tenodesis site. CONCLUSIONS: ASIIBT showed higher failure loads compared with IS and SA. Better construct performance of ASIIBT is due to greater absorption of distension forces which may improve final tenodesis healing. Also, the absence of an implant lowers additional costs and the chances for postoperative complications may be decreased significantly.

ABSTRACT

The authors report on the method, course and results of treatment of patients with meningococcal septicaemia. The two most common forms of meningococcal disease are meningococcal septicaemia (MS) and meningitis. Severe MS is a fulminant form of sepsis characterized by a rapidly spreading purpuric rash, haemodynamic instability and rapid progression to shock or death. The diganosis of MS was confirmed by isolation of NM in blood or cerebrospinal fluid, and/or positive solubile bacterial antigenes. However, in some children whose symptoms were consistent in MS (temperature and extensive purpura), no bacterial or soluble antigens were detected, particularly when they had been previours antibiotic treatment. Several scoring systems have been used to predict morbidity and mortility from MS. We selected the prognostic scor developed by Malley et al. Absolute neutrophil count less than 3 x 10(3)/mm3, platelet count less than 150 x 10(3)/mm3 and poor perfusion are indicators of poor prognosis. The presence of at least two of these indicators was associated with an 82% of risk of death. We reviewed the hospital records of 36 paediatric patients with acute meningococcal infection during a 5-year period. The age of our patients ranged from 2 months to 15 years (mean 4.4 yrs). Twenty seven (70%) of 36 children had MS and 11 (40.7%) had both MS and meningitis. Based on Malley scor, 13 (48.1%) patients had at least two predictors with > 82% of risk of lethal outcome. Four children (30.7%) died. Severe MS was diagnosed in 16 (59.2%) patients, who required mechanical ventilation (16; 59.2%), or continuous inotropic support and invasive measures of circulatory parametars (15; 55.5%). Shock treatment consisted of large volumes of crystalloid or colloid infusions thad ranged from 140 to 500 ml/kg/24 hrs (mean 215 ml/kg) Our results indicate that early controlled mechanical ventilations increase safety of large volume infusion with continuous invasive monitoring and inotropic stimulation, and may contribute to a greater survival of children with severe MS.

ABSTRACT

Schimke immuno-osseous dysplasia (OMIM *242900) is a rare autosomal recessive disorder that affects primarily the bone, the immune system, the kidneys, the skin and the vascular system. The patients have intrauterine growth retardation, short stature with short neck and trunk, peculiar clinical phenotype: triangular face, broad nasal bridge, bulbous nasal tip, small palpebral fissures, long upper lip and low hairline. The characteristic features include spondyloepiphyseal dysplasia, hyperpigmented maculae, proteinuria with progressive renal failure, lymphopenia with recurrent infections and cerebral ischaemia. We describe a girl, 5 years old, with short-trunk type of dwarfism (height 75 cm, below 3rd centile), short neck, accentuated lumbal lordosis and protruding abdomen. The patient had peculiar face with a broad, depressed nasal bridge, bulbous nasal tip, and slightly elongated upper lip. The hair was thin and sparse. Numerous pigmented spots resembling lentigines were visible on the trunk and abdomen. Radiographs showed spondyloepiphyseal dysplasia. At the age of 2 years laboratory analyses showed normal growth hormone secretion, normal thyroid function tests, normal female karyotype and no mucopolisachariduria. Since the age of 4 years, several episodes of transitory right-sided hemiparesis with spontaneous recovery, were observed. Seizures occurred at 5 years of age, when the MRI brain imaging showed multiple areas of ischaemia. She also experienced transient nephrotic syndrome, lymphopenia and low IgG accompanied by septicaemia.

ABSTRACT

West syndrome (WS) is an age dependent epileptic syndrome caused by various brain disorders. WS has been frequently classified in two groups, cryptogenic and symptomatic. As symptomatic WS consists of patients with numerous types of brain lesions, the prognosis and evolutional changes may be different among the types of brain lesions. WS is resistant to treatment to most conventional antiepileptic drugs, and only valproic acid, benzodiazepines, adrenocorticotropic hormone (ACTH), corticosteroids and vigabatrin have been found efficacious. Benzodiazepine, notably nitrazepam, and less clonazepam had been effective in bringing spasms under control but emerging tolerance and significant side effects (hypotonia and drowsiness) precluded its wider use. ACTH has been the treatment of choice for infantile spasms ever since Sorel and Dusaucy-Bouloye described its effectiveness in 1958. Despite the empirical approach steroids were capable of controlling the spasms and normalizing EEG in about 60% of cases. Corticotropin (ACTH) was used in doses from 5 to 180 I.U. daily, prednizolone 2-10 mg/kg daily, hydrocortisone 5-10 mg/kg daily and dexamethason 0.3-0.5 mg/kg. However, poor consensus was defined regarding the best steroid molecule to use, the dosage, and the duration of treatment. Also frequent and sometimes serious side effects have occurred during ACTH therapy, notably serious infections and hypertension that promoted continuous search for alternative and safer drugs tolerated outpatient treatment, good tolerance and minor side effects. Recently a specific visual field loss has been reported in treated adults that raised concern about safety of vigabatrin. New reports in children claim that vigabatrin treatment of children and adolescents has a lower risk for visual field defect than in adults, because of reported reversibility. Vigabatrin paediatric advisory group recommend the trial of vigabatrin for 12-14 days as first treatment for WS and in the case of good clinical response continuation of therapy for six months. Other new antiepileptic drugs (lamotrigine, topiramate, felbamate and zonisamide) have shown significant efficacy in the treatment of resistant WS to previous medication. The current task is to determine risk/benefit ratios of these two drugs (vigabatine, ACTH) and to delineate the group of patients with WS where their use would be optimal.

ABSTRACT

We report a case of a non-Hodgkin's lymphoma of the uterus and central nervous system in an 8-year-old female. The neurologic signs included blurred vision, neck stiffness, and walking difficulties but no abdominal problems. She deteriorated further, and repeated lumbar punctures revealed the presence of malignant cells in the cerebrospinal fluid. A repeated ultrasound scan of the abdomen demonstrated a markedly enlarged uterus. Biopsy revealed B-cell non-Hodgkin's lymphoma. Treatment according to the Berlin-Frankfurt-Münster protocol was initiated, but she developed hyperventilation syndrome and required mechanical ventilation. Her condition improved after 1 week but then deteriorated again, and despite additional chemotherapy she developed myelosuppression and septicemia with multiresistant Klebsiella pneumoniae and eventually died 13 months after her first admission to the hospital. No clinical or laboratory signs of relapse were evident at the time of death.

ABSTRACT

The first population-based study in the central region of the Republic of Serbia (total population 283,103) was carried out to assess some epidemiological features of febrile convulsions among children of between 6 months and 5 years of age. During the 10-year period, 1986 to 1995, there were 570 cases of the first febrile convulsions (287 males and 283 females). The average annual incidence rate was 3/1000 (2.9/1000 in males and 3.0/1000 in females), with the highest in 1995. During the study period, a significantly increased linear regression trend was observed. During the follow-up period of 5 years for children who had their first febrile convulsions in 1989 and 1990 (total 154 cases), 27 (17.5%) had a recurrence of the disorder, and ten (6.5%) had one or more afebrile seizures, of whom seven children (4.5% of total sample) developed epilepsy (recurrent afebrile seizures).

ABSTRACT

Hypotonia and weakness developed in a 12-month-old boy whose psychomotor development had previously been normal. The muscle biopsy demonstrated a disparity in the mean diameters of type 1 and type 2 fibers and satisfied major histologic criteria for diagnosis of congenital fiber type disproportion (CFTD). However, deterioration of motor and mental function, which developed subsequently, strongly suggested progressive encephalopathy. Examination of leukocyte cerebral enzymes at 15 months of age revealed a complete lack of galactosylceramide-beta-galactosidase. Selective type 1 fiber atrophy with type 1 fiber predominance has been observed in various conditions, including Krabbe disease. We report an additional case of Krabbe leukodystrophy associated with CFTD. The finding on the molecular level will resolve the dilemma of whether CFTD is a congenital myopathy or whether these patterns of disproportion may result from a number of different processes that interfere with the maturation of the developing motor unit.

ABSTRACT

Moraxella bovis was repeatedly isolated from cerebrospinal fluid in a girl with two episodes of shunt nephritis. Clinical remission of nephritis was achieved only after shunt replacement. A list of about 20 infectious agents reported to date in patients with shunt nephritis is given. M. bovis is yet another agent previously not reported in patients with shunt nephritis.

ABSTRACT

Two cases of glomerulonephritis associated with colonization of cerebrospinal fluid shunts inserted for the treatment of hydrocephalus (shunt nephritis) are described and additional 113 cases reported in world literature, are reviewed. Both of our patients were affected by two episodes of shunt nephritis. Complete clinical remission of renal disease followed antibiotic treatment in one patient, and shunt replacement combined with antibiotic therapy in the other. In the 115 cases of shunt nephritis reported to date, the causative organisms, clinical features, pathogenesis, renal histology, treatment, and outcome are discussed in detail. The importance of regular observation for early recognition of this reversible form of glomerulonephritis, is emphasized.

ABSTRACT

Spectral, acid-base, and redox properties of 4-mercaptoimidazoles were investigated by pulse radiolysis in aqueous solutions. Thiyl radicals of 1-methyl-5-ethyl-4-mercaptoimidazole (MEMI) have weak absorption band at 330 nm, epsilon = 300 +/- 60 M-1 cm-1. Because the ionic strength variation from 0.01 to 0.1 M in the pH range from 3 to 14 does not influence the rate constant of the radical decay, it is concluded that the MEMI thiyl radical is neutral. At pH 7, the reduction potential of the MEMI radical, E7 = 0.45 V, is lower than E7 = 0.48 V of the Trolox C radical, which means that MEMI may restitute vitamin E under physiological conditions (assuming similar reduction potentials of Trolox C and vitamin E radicals). Because pKa = 10.3 of the SH group in MEMI is lower than pKa = 11.9 of the OH group of Trolox C, the redox equilibrium with Trolox C is reversed at pH 13, and E13(MEMI-radical) = 0.29 +/- 0.04 V is determined against E13(Trolox C--radical) = 0.19 V. In contrast to extraordinary electron donating properties, MEMI is only a moderately good H-atom donor. k(.CH3 + MEMI) = (1.5 +/- 0.3) x 10(5) M-1 s-1 in neutral media is considerably lower than k(.CH3 + GSH) = 5 x 10(7) M-1 s-1, which is explained by the zwitterionic structure of MEMI. The ability of MEMI to act as antioxidant in biological systems is further demonstrated by its ability to efficiently scavenge superoxide and linoleate peroxyl radicals.(ABSTRACT TRUNCATED AT 250 WORDS)

ABSTRACT

Distinction of patients with Angelman's syndrome in a group of mentally retarded patients is important even though the syndrome was rarely reported since the original description in 1965. Before that time these patients were thought to suffer from neurologic sequelae of perinatal asphyxia, Lennox-Gastaut syndrome or mental retardation of unknown origin. Diagnosis is based on the following criteria: developmental delay from early age, absent speech (or speech limited to less than six words), jerky movements with an ataxic gait if the patient is walking, paroxysm of inappropriate laughing, dysmorphic craniofacial features (brachycephaly, mid-facial hypoplasia, deep set eyes, macrostomia, prominent mandible). About 60% of patients have deletion of chromozome 15q11-13. Cytogenetic studies suggest that de novo deletion of chromozome 15 is connected with the low recurrence risk and that families with several members with Angelman's syndrome belong to the group without identifiable deletion on citogenetic or molecular level. The article deals with the diagnostic criteria, clinical features and electroencephalographic changes (after several years of followup) in seven children with Angelman's syndrome (four girls and three boys).

ABSTRACT

It is well known that certain hereditary diseases of the nervous system sometimes occur concurrently within particular families. This report presents a Yugoslav family of Hungarian origin in whom 2 brothers had progressive myoclonic epilepsy and proximal weakness and atrophy of muscles. Electromyography and muscle biopsy confirmed neurogenic atrophy. Electroencephalography disclosed paroxysmal spike-and-wave and polyspike-and-wave complexes with photic-induced myoclonic jerking. The combination of these clinical features is extremely rare and probably constitutes a clinical syndrome that has not been reported previously.

ABSTRACT

A 14-month-old severely retarded girl with a history of regurgitation, aspiration, and recurrent pneumonia was found to suffer from diffuse oesophageal spasm. This diagnosis was made by oesophageal cineradiography. This case suggests that diffuse oesophageal spasm is an oesophageal motility disorder that causes respiratory disease in the retarded child.

ABSTRACT

Secondary hyperparathyroidism is common in chronic renal failure and is due to inadequate synthesis of calcitriol, the active metabolite of vitamin D. Intravenous administration of alphacalcidol, a synthetic analogue which is metabolized to calcitriol, was given during 12 weeks to 51 patients on chronic hemodialysis in doses between 1 and 4 micrograms/dialysis session. The treatment caused a modest rise, by 0.25 mmol/l, in serum calcium but a 60% reduction of intact serum PTH concentrations. Most patients acquired normal PTH values and hypercalcemia was easily avoided by dose adjustments. There was a significant reduction in serum PTH within the 1st week before the serum calcium concentrations were increased, but after that time the induced suppression of PTH was correlated to the induced rise in serum calcium. These observations are compatible with the view that calcitriol exerts both a direct inhibition of PTH release and increases the gland's sensitivity to calcium. The major implication of the study is that intravenous treatment with alphacalcidol is of great clinical value since it is easy to administer and provides suppression of hypersecretion of PTH with few side effects.
