Immunoglobulin replacement therapy contribution in agammaglobulinemia: 10 case reports]

Intravenous immunoglobulin (Ig IV) has been used for many years in the treatment of primary antibody deficiencies. We performed a retrospective study of the clinical features and outcome of agammaglobulinemia children who received prolonged Ig IV infusions. PATIENTS AND METHODS: Ten children, 9 male et 1 female, with agammaglobulinemia diagnosis were studied for the clinical manifestations before and during the Ig IV replacement therapy. Serum Ig levels were quantified by nephelometry. Circulating B ant T cells were counted by immunofluorescence labeling by monoclonal antibodies. T-cell functions were assessed by using mitogen and antigen -induced T-cell proliferation assays in vitro. Patients clinical status was evaluated respectively, before initiation and at every moment (when patients had an infection) of the replacement therapy. RESULTS: Ig IV therapy was performed for 866 cumulated months, median 108 months. The median Ig IV doses administered to the 10 patients was 500 mg/kg/month. Residual serum IgG mean level was 3,9 g/L. All patients had 99 bacterial infections/year before Ig IV, mainly respiratory tract infections (48,5%), and 4 patients had bronchiectasis before Ig replacement therapy. The number of infection/year fall to 25 during IgIV replacement, and the infection/patient/year rate decreases significantly. One patient developed an Echovirus 27 meningoencephalitis during this treatment. CONCLUSION: Ig IV therapy with residual IgG mean level of 3,9 g/l reduced significantly the rate of bacterial infections. The use of specific antibiotherapy and respiratory kinesitherapy led to a lower rate of respiratory tract infections, and the stabilisation of the bronchiectasis. However this intravenous replacement therapy does not protect against viral meningoencephalitis.     

Three cases of infection withFusarium species in neutropenic patients

Three cases are reported of disseminated infection due toFusarium species in severely neutropenic patients. The clinical findings in all patients included fever, painful disseminated nodular skin lesions and severe myalgia. The outcome was fatal despite early administration of amphotericin B. The portal of entry of the organism was probably the nasal sinus in two cases.     

Detection and molecular typing of human papillomaviruses: prevalence of cervical infection in the Tunisian central region

There are compelling molecular and epidemiological data which indicate that infection with certain genital human papillomaviruses (HPVs), such as HPV 16 and HPV 18, has a critical role in initial changes that lead to cervical and probably other anogenital cancers. These observations prompted us to investigate the prevalence of cervical infection with genital human papillomaviruses in Tunisia. We used the polymerase chain reaction (PCR) to detect and type HPV DNA. The prevalence of HPV infection in a population of 106 Tunisian women recruited at the Offices Nationaux de la Famille et de Population (ONFP) was 13.6%. Molecular HPV typing indicated a high prevalence of HPV at high oncogenic risk; Our results indicate that the infection with genital human papillomaviruses is frequent in the Tunisian population.     

Callosotomy in the treatment of "catastrophic" drug-resistant epilepsy in children

The aim of this paper was to assess the preliminary results of callosotomy in children with "catastrophic" drug-resistant epilepsy. During the last 5 years, we performed callosotomy in 8 cases. Indications were: "catastrophic" drug-resistant epilepsy with frequent seizures, progressive psychomotor and intellectual deterioration, generalised structural and functional abnormalities in neuroimaging and neurophysiological studies. These children were of the mean age of 6 years, with the mean duration of illness 58 months. In the mean follow-up time of 27 months the following results were obtained: Engel class II--3 cases; class III--4 cases and class IV--1 case. Any intellectual improvement was noted in 2 cases only. CONCLUSIONS: (1) callosotomy effectively reduces the frequency and severity of seizures in children with drug-resistant epilepsy; (2) in spite of reduced seizures, in the majority of cases no significant psychomotor and/or intellectual improvement was achieved; (3) callosotomy did not produce any permanent morbidity.     

Nosocomial outbreak of acute gastroenteritis in a neonatal intensive care unit in tunisia caused by multiply drug resistantSalmonella wien producing SHV-2 beta-lactamase

In a Tunisian hospital 27 babies, including 12 who were premature, in a single intensive care unit suffered acute gastroenteritis in the period from January to May 1988. The mean age at the onset of gastroenteritis was 8.4 days; nine babies died.Salmonella wien was isolated from stools (all babies) and blood (4 babies). It was also isolated from the stools of one nurse and from a mattress. Twelve of the babies had received cefotaxime, which was successfully replaced by oral colimycin. The outbreak was stopped by the implementation of infection control measures. All isolates ofSalmonella wien were of the same biotype, and had the same antibiotic resistance pattern (third generation cephalosporins, monobactams, aminoglycosides, chloramphenicol, trimethoprim and sulphonamides) and plasmid DNA restriction pattern. The isolates were all susceptible to a combination of cefotaxime and clavulanic acid (a -lactamase inhibitor), which displayed synergy, suggesting the presence of a -lactamase (geometric mean MICs 11.24 µg/ml for cefotaxime alone and 0.24 µg/ml in combination with 0.1 µg/ml potassium clavulanate). All isolates produced TEM-1 and SHV-2 -lactamase which was not transferable toEscherichia coli by conjugation. The presence of the SHV-2 enzyme inSalmonella wien may allow it to adapt to newer -lactams which is a cause for concern in this hospital.     

Surgery for bilateral outflow tract obstruction in elastin arteriopathy

OBJECTIVE: A number of patients with Williams syndrome or other forms of elastin arteriopathy have stenoses of pulmonary arteries in addition to supravalvular aortic stenosis. We sought to investigate the effect of the degree of pulmonary arterial stenosis on the prognosis after an operation for supravalvular aortic stenosis to help define the optimal treatment strategy for patients with severe forms of elastin arteriopathy. METHODS: Between 1960 and 1999, 33 patients underwent operations for supravalvular aortic stenosis while having significant stenoses of the pulmonary arteries. We retrospectively reviewed patient charts, obtained current follow-up information, and determined risk factors for survival and reoperation. RESULTS: Fifteen patients with moderate right-sided obstructions (confirmed by pulmonary artery Z-scores and right ventricular/descending aortic pressure ratio) underwent operations for supravalvular aortic stenosis only. Eighteen patients had more severe right-sided obstructions and underwent surgical relief of pulmonary arterial stenoses or right ventricular outflow tract obstruction in addition to operations for supravalvular aortic stenosis. Eight patients had undergone preoperative balloon dilations of stenotic pulmonary arteries. There were 6 early deaths and 1 late death in our series. Survival at 10 and 20 years was 76% (70% confidence interval, 68%-84%) and freedom from reintervention was 59% (70% confidence interval, 46%-71%) at 10 years and 49% (70% confidence interval, 35%-62%) at 20 years. Multivariate analysis revealed that patients with a right ventricular/descending aortic pressure ratio of 1.0 or more were at higher risk for reintervention but not for death. CONCLUSIONS: Surgical treatment of pulmonary artery obstructions in elastin arteriopathy is palliative but, in conjunction with balloon dilation of peripheral pulmonary arteries, offers good long-term survival to patients with the severest form of elastin arteriopathy.     

Diagnostic and therapeutic advantages of rigid ureteroscopy: retrospective study of 304 cases

Uretroscopy has become a common tool for the diagnosis and management of the upper urinary tract. Between April 1994 and Decembre 1999, 304 ureteroscopy procedures were performed. The most common therapeutic procedure was stone manipulation in 299 cases (distal ureter 259 cases, mid-ureter 23 cases, lumber ureter eight cases and staged in nine cases). Procedure was made by a rigid ureteroscope 8.5 Ch or 11.5 Ch. Dorinia was used in 175 cases (57.5%) with or without fragmentation by ultrasound. Therapeutic ureteroscopy was also used to remove a double-J stent that had migrated into the pelvic ureter in one case and in three cases of ureteral tumor. It was used in one case to confine the extrinsic compression of a ureteral stenosis. Median follow up was 12 months (6-36 months). The overall success rate was 87.6%. Results are comparable in men and women (P = 0.8). Success rate was 90% in single lithiasis and 76.2% in case of numerous stones (P = 0.0094). There was a statistically significant difference in success rate between stones 15 mm or under in size (89% stone-free) and those 15 mm (66% stone-free) or larger. In conclusion, rigid ureteroscopy is a minimally invasive and reliable technique for the management of ureteric calculi and for the diagnosis and treatment of other ureteric lesion.     

Minimal access approach for the repair of atrial septal defect: the initial 135 patients

BACKGROUND: From May 1996 to August 1998 a minimal access approach was used for 135 of 200 consecutive surgical atrial septal defects closures in children through young adults ranging in age from 6 months to 25 years (median 5 years). METHODS: A 3.5- to 5-cm midline incision was centered over the xiphoid with division of the xiphoid alone (transxiphoid) or of the lower sternum (ministernotomy); both groups underwent bicaval venous cannulation through the incision. Cardioplegia and aortic cross-clamping were administered through the incision. Cephalad retraction of the sternum with a fixed-arm retractor aided exposure. RESULTS: There have been no early or late deaths and no bleeding or wound complications. No procedure required conversion to a full sternotomy, and no cannulation attempt was abandoned for an alternate site. Cross-clamp and cardiopulmonary bypass times were equivalent to those in the full sternotomy group. The mean length of hospital stay in the ministernotomy group was 2.7 days. CONCLUSIONS: The closure of atrial septal defects can be performed through a transxiphoid or ministernotomy approach, conferring a satisfactory cosmetic result without compromising the safety or accuracy of the repair.     

Correlation of optic nerve sheath diameter measurements by computed tomography and magnetic resonance imaging

BackgroundTraditionally, intracranial pressure is measured by direct ventriculostomy, which is invasive. Noninvasive measures such as bedside ultrasound and magnetic resonance imaging have been advocated and utilized recently to assess the intracranial pressure. The role of this study is to determine the degree of agreement between measurements of the optic nerve sheath diameter by computed tomography (CT) and magnetic resonance imaging (MRI).Materials and MethodsRetrospective chart review of 100 consecutive patients who had both MRI and CT scan of the head from January 1, 2011, until March 31, 2013, at our center was performed. A discrepancy of 0.2 mm between the 2 measurements was set as acceptable difference. The measurements of optic nerve sheath diameter (ONSD) were compared for agreement between the 2 modalities using the method by Bland and Altman.ResultsA total of 100 patients with both MRI and CT scan of the head were selected. Of these 100 patients, 24 were male and 76 were female. The average age was 63 years. No ONSD abnormality was detected in any of the patients. The discrepancy in measurements of the ONSD between CT and MRI in transverse plane was less than the predetermined cut-off value of 0.2 mm. Within-subject variance was estimated at 0.0058 for both CT and MRI.ConclusionComparable results without significant discrepancy as predetermined by the study groups were obtained from CT scan. Measurement of ONSD by CT scan can be used to indirectly asses the intracranial pressure in addition to clinical assessment and other signs of increased intracranial pressure on CT scan.
