Establishment of alien registration requirements, 7 January 1988.

On 7 January 1988, the Immigration Commissioner of the Philippines announced that all temporary or permanent aliens resident in the Philippines were required to register with the Commission on Immigration and Deportation in order to legalize their stay in the country. Those who failed to register by a March deadline were subject to immediate deportation. The Commission also set a P500,000 reward for those giving information on the whereabouts of overstaying or undesirable aliens. Effective 21 November 1988, President Corazon Aquino ordered the alien legalization program to be suspended.

Rat aortic smooth muscle cells isolated from different layers and at different times after endothelial denudation show distinct biological features in vitro.

Endothelial denudation by balloon injury of the rat aorta induces the development of a neointima as a consequence of the migration and proliferation of smooth muscle cells (SMCs). Initially, intimal SMCs show a dedifferentiated phenotype, which reverts to a normal differentiated phenotype after endothelial cells have resurfaced the vessel lumen. We investigated in vitro the proliferative and phenotypic features of SMCs from different layers of rat aorta isolated 15 and 60 days after endothelial denudation. Freshly isolated intimal cells 15 days after balloon injury (IT-15) appeared rounded and showed a decreased content of alpha-smooth muscle actin, smooth muscle myosin, and desmin compared with intimal cells isolated 60 days after balloon injury (IT-60). No morphological and cytoskeletal differences were observed among freshly isolated IT-60 cells and other medial populations, which included medial SMCs that underlie the intimal thickening. In culture, IT-15 cells showed increased proliferative activity both in monolayers and in free-floating collagen lattices. Decreased expression of alpha-smooth muscle actin and smooth muscle myosin was documented in IT-15 cells compared with IT-60 cells and other medial SMC populations in monolayer. Moreover, IT-15 cells suspended in collagen lattices were poor at contracting these collagen lattices compared with IT-60 and control SMCs. IT-60 cells were equivalent to control SMCs at lattice contraction except for a temporary delay at day 1.(ABSTRACT TRUNCATED AT 250 WORDS)

The impact on eating habits of temporary translocation from a Mediterranean to a Northern European environment.

OBJECTIVE: To assess the effect of temporary translocation from a Mediterranean to a Northern European environment on the eating habits of a group of foreign students. DESIGN: Cross-sectional survey of eating habits before and after moving from Greece to Glasgow, Scotland. SETTING: University of Glasgow. SUBJECTS: Eighty post-graduate Greek students. INTERVENTIONS: A self-administered questionnaire comprising of three major sections: (1) general eating habits; (2) frequency of eating selected food items; (3) opinion of food availability in Glasgow. RESULTS: After moving to Glasgow, significant decreases were reported in the frequency of consuming fresh fruit, raw vegetables, fish, legumes, meat, poultry and fresh fruit juice. The frequency of eating biscuits, savoury snacks, soft/fizzy drinks, alcoholic drinks and mayonnaise, dips and sauces increased. The estimated median daily consumption of fruit and vegetables decreased from 363 g in Greece to just 124 g in Glasgow, well below the Scottish and WHO dietary target of 400 g/day. The main perceived barriers to maintaining customary eating habits were the price of food, the lack of familiar tastes, the greater availability of convenience food and the limited variety of food available in Glasgow, when compared to Greece. CONCLUSIONS: These findings highlight the difficulties that migrant populations face in retaining traditional, often healthier, eating habits when migrating to a foreign country. Barriers of high cost, limited availability and poor quality of familiar foods, need to be addressed in order for migrants to maintain their customary eating patterns. Furthermore, these barriers need to be addressed before nutritionists can expect to see the widespread adoption of the Mediterranean diet by Western populations less familiar with this eating pattern.

A novel intraurethral prostatic bridge catheter for prevention of temporary prostatic obstruction following high energy transurethral microwave thermotherapy in patients with benign prostatic hyperplasia.

PURPOSE: We evaluate the efficacy and safety of a novel intraurethral prostatic bridge catheter in preventing temporary prostatic obstruction following targeted high energy transurethral microwave thermotherapy in patients with benign prostatic hyperplasia. MATERIALS AND METHODS: A total of 54 patients with benign prostatic hyperplasia underwent high energy transurethral microwave therapy under topical urethral anesthesia followed by placement of a prostatic bridge catheter, which remained indwelling as long as 1 month (prostatic bridge catheter group). Patient evaluation included determination of peak urinary flow rate, International Prostate Symptom Score (I-PSS) and quality of life score at baseline, immediately following transurethral microwave therapy and prostatic bridge catheter placement, and periodically thereafter for 1 month. Results were retrospectively compared with those of 51 patients who underwent transurethral microwave therapy followed by standard temporary urinary catheterization, typically for 24 hours (standard catheterization group). RESULTS: Immediately following transurethral microwave therapy and prostatic bridge catheter placement significant improvements (p <0.0005) were observed in mean peak flow rate, I-PSS and quality of life score of 59.3, 33.5 and 23.6%, respectively, compared with baseline values. Further improvements were noted up to 1 month, at which time mean peak flow rate, I-PSS and quality of life score had improved 79.0, 54.9 and 56.5%, respectively, versus baseline (p <0.0005). In a retrospective comparison at baseline and 14 days between the prostatic bridge catheter group and standard catheterization group mean baseline peak flow rate, I-PSS and quality of life score were similar. However, at the 14-day followup evaluation in the prostatic bridge catheter group mean peak flow rate was 101.8% higher, and I-PSS and quality of life score were 47.9 and 51.1% lower, respectively, than the corresponding values in the standard catheterization group (p <0.0005). The prostatic bridge catheter was well tolerated and remained indwelling throughout the entire 1-month followup in 48 of 54 patients (88.9%). Early prostatic bridge catheter removal was required in 3 patients (5.6%) due to urinary retention and in 3 (5.6%) due to catheter migration. CONCLUSIONS: Prostatic bridge catheter placement provides an effective and well tolerated option for preventing prostatic obstruction in the acute period after transurethral microwave therapy. This approach avoids the inconvenience and infection risk of standard indwelling catheters or intermittent self-catheterization. Prostatic bridge catheter insertion and removal are rapid, facile, nontraumatic procedures. Prostatic bridge catheter may potentially be used in an array of minimally invasive procedures involving thermal treatment of the prostate gland.

Survey of bisphenol a diglycidyl ether (BADGE) in canned foods.

2,2-Bis(4-hydroxyphenyl)propane bis(2,3-epoxypropyl) ether (BADGE) is used in the manufacture of lacquers for coating the inside of food and beverage cans. In June 1996 the EC Scientific Committee for Food temporarily increased the specific migration limit applying to BADGE to 1 mg/kg pending consideration of additional toxicological data. In order to find out if there is migration of BADGE from can coatings into foods, a 'worst case' sampling exercise has been conducted to survey those canned foods where the propensity for migration of BADGE was judged to be highest. The foods surveyed include canned fish in oil, meat and milk and, altogether, BADGE was determined in 181 retail samples. Analysis for BADGE was conducted, in duplicate, by HPLC with fluorescence detection with confirmation of BADGE identity by GC/MS analysis using selected ion monitoring. BADGE was found at levels exceeding 1 mg/kg in seven of the 15 canned anchovy samples and five of the 22 sardine samples purchased during the period September 1995-July 1996. Infrared analysis of the can coatings provided strong evidence that the higher BADGE levels found were associated with use of PVC organosol lacquers, although in some cases cans coated with organosols gave low BADGE results. For canned sardine samples found to contain greater than 0.5 mg/kg BADGE in the total contents, a replicate can was opened and separate analyses performed on the drained fish and the oil. The results clearly showed that BADGE concentrations in the oil were about 20 times higher than in the drained fish. Further samples of canned sardines and anchovies were purchased in June/July 1997 and, in all cases, BADGE levels were found to be below 1 mg/kg. In the other retail canned foods, BADGE was not detectable (DL = 0.02 mg/kg) or detected at concentrations well below the temporary SML of 1 mg/kg.

Repositioning of a dislodged and fibrosed ventricular lead.

UNLABELLED: This is a case of a 61 year old African American female with history of end stage renal disease on hemodialysis. She had a dual chamber permanent pacemaker implanted in 2003 for symptomatic bradycardia. Over the past several months the patient had problems with access for dialysis. The right arm AV fistula was occluded. The patient had multiple temporary central catheter placed for dialysis over the past 3 months. The patient was admitted for superior vena-cava syndrome. CT scan of the thorax and neck showed occluded right and left subclavian system. An incidental finding was the right ventricular (RV) lead been dislodged and the tip being in the inferior vena cava. Surgical and non-surgical options were discussed with the patient and she chose to go the less invasive route. The patient underwent a RV lead revision. Using different stylets the RV lead was repositioned in the RV with good pacing and sensing characteristics. CONCLUSIONS: Successful repositioning of an old dislodged RV pacing lead using stylets and eliminating the need for invasive procedure like lead extraction.

Decree No. 1991, Regulations to the Law on Foreigners, 30 June 1986.

Among other things, these Regulations set forth rules on requirements for visas established in the Ecuador Law on Foreigners. They list the amounts of income from abroad or investments in Ecuador required of foreigners entering Ecuador with immigrant visas, documents needed by persons working permanently in enterprises and institutions under immigrant visas, and methods of proof of dependency for persons entering on immigrant visas as dependents. In this context, they provide that persons with foreign income must receive at least $1,000 per month, with an increase of 80% Ecuadorian personnel; that persons entering as workers must inform authorities of changes in work status; and that persons entering as dependents may themselves work only if their sponsor dies or the means of subsistence of the sponsor decrease. The Regulations also set forth requirements for persons entering Ecuador on nonimmigrant visas, such as refugees, students, temporary workers, religious personnel, and those in transit. With respect to refugees, the rules provide that false statements made in an application will trigger an expulsion order; that foreign nationals coming from a country other than that where they suffered persecution will not be admitted unless they were in that country in direct transit; that refugees may not leave the country without express permission; and that, if the conditions justifying asylum change, a refugee will be required to leave the country. With respect to workers, the rules provide that an applicant must show a need for a foreign worker that cannot be fulfilled by an Ecuadorian worker and must show a work contract or appointment. With respect to those in transit, the rules provide that no visa is required and that entry will be denied to those lacking permission to enter the country of destination and transit through countries bordering Ecuador that are on their route. Persons in this category may stay in Ecuador for only a limited time--usually 10 days for persons en route and three months for visitors. The Regulations also contain provisions on the modification of immigration status, including the rule that the status of those in transit may not be modified. In addition, they set forth the functions of the Consultative Council on Migration Policy. Among these is the task of promoting internal migration to sparsely populated areas of the country.

Misplacement of a right internal jugular vein haemodialysis catheter into the mediastinum.

A 69-year-old woman with end-stage renal failure discontinued continuous ambulatory peritoneal dialysis and commenced temporary haemodialysis because of resistant peritonitis. Right internal jugular vein haemodialysis catheter placement was performed. The cuffed, tunnelled haemodialysis catheter was inserted using the modified Seldinger technique. When haemodialysis was initiated the following day, blood could not be aspirated from the catheter and the patient complained of central chest pain during the aspiration. Subsequent venography and computed tomography scan of the thorax showed that the catheter was placed extraluminally into the posterior mediastinum. The importance of a chest radiograph after placement of a central venous catheter is highlighted by this case report. Subtle deviations in catheter position from normal should alert the physician to the possibility of catheter misplacement and lead to further investigation.

A novel inhibitor of Rho-associated protein kinase, Y-27632, ameliorates hepatic ischemia and reperfusion injury in rats.

BACKGROUND: A Rho-ROCK signal system induces vascular contraction and neutrophil migration, both of which are characteristic features found with ischemia and reperfusion injury of the liver. We tested our hypothesis that a novel ROCK I inhibitor, Y-27632, attenuates hepatic ischemia and reperfusion injury. METHODS: Rats underwent 70% partial hepatic ischemia for 120 minutes and subsequent reperfusion. Y-27632 of 10mg/kg was given orally 1 hour before ischemia, while distilled water was given to the control animals. One week animal survival, systemic hemodynamics, hepatic tissue blood flow, liver function tests, plasma endothelin-1, serum hyaluronic acid levels, myeloperoxidase activity and malondialdehyde level in liver tissue, membrane attack complex-1 and intracellular adhesion molecule-1 staining, and histological architecture were analyzed. RESULTS: Y-27632 prolonged 1-week animal survival from 25% of untreated animals to 75% accompanied with significant amelioration of hepatic tissue blood flow, liver function tests and histological architecture without any adverse effects on systemic hemodynamics. In addition, plasma endothelin-1 and serum hyaluronic acid levels decreased markedly compared to the control, concomitant with remarkable suppression of membrane attack complex-1 stain positive neutrophils infiltration, myeloperoxidase activity and malondialdehyde level. CONCLUSION: Present study suggests that activation of a Rho-ROCK signal system is associated with ischemia and reperfusion injury of the liver, and that Y-27632 may be an attractive agent for application in major liver resection using temporary inflow occlusion and hepatic preservation.

Use of transfer factor in patients with depressed cellular immunity and chronic infection.

Two patients with chronic mucocutaneous candidiasis and a defect in cellular immunity received a single injection of dialysable transfer factor from Candida-positive donors in an effort to reconstitute immunologic function. The transfer of cellular hypersensitivity was successful in one of the two patients and was monitored by skin tests and MIF production; however, the effect was temporary and did not change the clinical course of the patient's infection. The other patient did not respond eitherimmunologically or clinically to transfer factor at this time, although she did respond subsequently to repeated doses of transfer factor and amphotericin B therapy (Pabst and Swanson: Brit. med. J. 2:442, 1972). In another instance transfer factor from tuberculin-positive donors was used successfully to eradicate an infection in a patient with progressive primary tuberculosis and an acquired defect in cellular immunity. The patient had not responded clinically or bacteriologically after 7 1/2 months of antituberculous therapy, although the organism was shown to be sensitive in vitro to the drugs she was receiving. She received 6 doses of dialysable transfer factor over a 3-month period and during this time she responded clinically, bacteriologically and roentgenographically.

[Perforation of a temporary transvenous pacemaker electrode in the left hemithorax. Diagnostic value of echocardiography].

We report a rare malposition of a temporary transvenous pacemaker electrode. A pacemaker electrode was inserted in a patient with acute postero-lateral infarction. The correct position of the electrode tip was controlled by fluoroscopy. Capture and sensing functions worked regularly. Four days later, angina-pectoris-like complaints occurred again. Chest x-ray film revealed the tip of the electrode in the left hemithorax. Echocardiographic assessment showed a penetration through the interventricular septum into the left ventricle. The electrode passed the left ventricle, penetrated the anterior-lateral free wall and reached the left pleural space. A thoracotomy was performed immediately. The electrode was retracted under visual control. A spurting arterial bleeding from the left ventricle was secured with a purse-string ligature. This case report emphasizes the value of echocardiography in the evaluation of a malposition of a transvenous pacemaker electrode.

Cells in the marginal zone of the spleen.

The marginal zone of the spleen forms an intriguing area in which a variety of cell types are combined. Several of these cell types seem to have a fixed position in the marginal zone, such as the marginal zone macrophages, the marginal metallophilic macrophages at the inner border, and, to a lesser extent, the marginal zone B cells. For other cell types--T lymphocytes, small B cells, and dendritic cells--the marginal zone is only a temporary residence. It is this combination of relatively sessile cell populations and the continuous influx and passing of bloodborne immunocompetent cells that turn the marginal zone into a dynamic area, particularly apt for antigen processing and recognition. In no other lymphoid organ can such a unique combination of cells and functions be found. The opening of the arterial blood stream in the marginal sinuses results in a reduction of the velocity of the blood stream, and antigens are initially screened in the marginal zone. To this, extremely potent phagocytic cells, the marginal zone macrophages, are present which can take up and phagocytize large foreign particles, such as bacteria and effete red blood cells. Further filtration of the blood takes place in the filtration beds of the red pulp. The marginal zone macrophages express membrane receptors for bacterial polysaccharides which lead to efficient phagocytosis, probably even in the absence of prior opsonization. Antigenic fragments produced this way can be taken up by dendritic cells that enter the spleen by the blood as part of a mobile surveillance immune system. Dendritic cells present antigen to T cells in the outer area of the T cell-dependent PALS, leading to clustering and enrichment of antigen-specific T cells. Antigens in the marginal zone can also directly associate with memory B cells thought to reside here for longer times, having intimate contact with the marginal zone macrophages. B memory cells then migrate into the PALS and present antigen to T cells. The marginal zone therefore functions not only as an area of initial filtration and phagocytosis of antigens from the blood, but also as a site of lymphocyte emigration. Some of the incoming T and B lymphocytes in the recirculating pool enter the white pulp from the marginal zone. The underlying force and selective molecular mechanisms that guide this migration are unknown. Both B and T lymphocytes recirculate through the outer PALS area on their way to the follicles and the inner PALS, respectively.(ABSTRACT TRUNCATED AT 400 WORDS)

Effects of displacement resulting from ethnic/religious conflict on the growth and body composition of Fulani children in northern Nigeria.

This study, which was carried out in the Jos Plateau in Nigeria, analysed the changes in growth and body composition that occurred among 17 male and 13 female Fulani children (aged 4-13 years) in the 7-month period which followed their displacement from their homes into a temporary camp due to ethnic/religious violence. The heights and weights of the children, as well as their fat, fat-free mass, and phase angle were determined 3 weeks before the crisis and 7 months post-crisis using standard anthropometric methods and bioelectrical impedance analysis. In terms of mean values and relative to growth curves established during the tranquil period immediately preceding the crisis, all but one of the girls grew taller and gained more weight than predicted; two-thirds of the weight gained by the girls was due to fat. With regard to the male subjects, on average, while they grew taller, they gained 30 per cent less in height than predicted. However, the boys did gain 50 per cent more weight than predicted. Unexpectedly, fat accounted for one-half or more of the weight gain in both the boys and girls. In general, the boys did less well than the girls in the months following the crisis. The phase angle of all subjects did not decline significantly during the pre- and post-crisis interval. In general, from the nutritional perspective, the Fulani children coped relatively well during the 7-month period of displacement. The fact that neither the growth nor body composition of the Fulani children deteriorated significantly following the crisis was attributed to the fact that during that period they were receiving adequate and continuous supplies of food. Furthermore, the displacement camp into which the children and their families migrated was located in a secure region of the country and one that was controlled by people whose culture and ethnicity were similar to theirs. Finally, at no time during their 7 months as a displaced population were the children separated from their mothers. In conclusion, this study shows that displacement in general may not necessarily lead to deleterious effects on the growth of children.

Fine-scale spatial genetic structure and dispersal among spotted salamander (Ambystoma maculatum) breeding populations.

We examined fine-scale genetic variation among breeding aggregations of the spotted salamander (Ambystoma maculatum) to quantify dispersal, interpopulation connectivity and population genetic structure. Spotted salamanders rely on temporary ponds or wetlands for aggregate breeding. Adequate breeding sites are relatively isolated from one another and field studies suggest considerable adult site fidelity; therefore, we expected to find population structure and differentiation at small spatial scales. We used microsatellites to estimate population structure and dispersal among 29 breeding aggregations in Tompkins County, New York, USA, an area encompassing 1272 km(2). Bayesian and frequency-based analyses revealed fine-scale genetic structure with two genetically defined demes: the North deme included seven breeding ponds, and the South deme included 13 ponds. Nine ponds showed evidence of admixture between these two genetic pools. Bayesian assignment tests for detection of interpopulation dispersal indicate that immigration among ponds is common within demes, and that certain populations serve as sources of immigrants to neighbouring ponds. Likewise, spatial genetic correlation analyses showed that populations < or = 4.8 km distant from each other show significant genetic correlation that is not evident at higher scales. Within-population levels of relatedness are consistently larger than expected if mating were completely random across ponds, and in the case of a few ponds, within-population processes such as inbreeding or reproductive skew contribute significantly to differentiation from neighbouring ponds. Our data underscore the importance of these within-population processes as a source of genetic diversity across the landscape, despite considerable population connectivity. Our data further suggest that spotted salamander breeding groups behave as metapopulations, with population clusters as functional units, but sufficient migration among demes to allow for potential rescue and recolonization. Amphibian habitats are becoming increasingly fragmented and a clear understanding of dispersal and patterns of population connectivity for taxa with different ecologies and life histories is crucial for their conservation.

Sociopolitical adjustment among Afghan refugees in Pakistan.

Although international organizations and Pakistanis expect Afghans to act like true refugees--dependent, obedient, and grateful--Afghans consider themselves as temporary exiles who, in protest against an anti-Islamic government, found temporary refuge in Pakistan; or as soldiers in the holy wars who temporarily use their Islamic neighbor as a base before returning to fight in Afghanistan. Conforming to this concept and to these objectives, the refugees seek to preserve a certain autonomy and to lean towards forms of organization which are derived either from their traditional social structure, or as is more common now, from the ideology of the Islamic movements. One can understand that this situation may cause many misunderstandings, especially with international organizations which finance and supervise aid to the Afghan refugees in Pakistan. As for anthropologists, it is necessary to go beyond known concepts, to relativize familiar models and to act on changes which have come about in the structures and ideology of the Afghan people.

Transient production of stem cell factor in dermal cells but increasing expression of Kit receptor in mast cells during normal wound healing.

Mast cells are involved in inflammatory skin disorders and wound healing processes, but the mechanism behind mast cell activation is obscure. In this study, we stained the stem cell factor (SCF) and the Kit receptor in tryptase-positive mast cells, since these molecules are essential for mast cell survival, growth, migration and activation. For this purpose, biopsies were taken from the edge of normally healing wounds of 12 patients undergoing skin transplantation on days 0, 1, 3, 7 and 14, and from chronic leg ulcers and psoriatic skin for comparison. In healing wounds, SCF-positive cells rapidly increased in number in the dermis peaking on day 1, but declined thereafter to their baseline values. The percentage of Kit-positive mast cells increased slowly but steadily reaching a maximum (73+/-22%, P=0.02) on day 14. In chronic ulcers, most of the mast cells were Kit-positive both in the wound bed and in the perilesional skin (87+/-9% and 86+/-13%, respectively). The number of SCF-positive cells was higher in the wound bed than in the dermis of perilesional skin. In the psoriatic skin of ten patients, lesional specimens showed significantly higher numbers of SCF-positive dermal cells as well as a higher percentage (88+/-12% vs 46+/-26%, P=0.004) of Kit-positive mast cells than nonlesional skin. In conclusion, our findings show that the expression of SCF increases rapidly in the early stages of wound healing but declines thereafter, whereas the expression of Kit in mast cells is induced slowly in healing wounds. In chronic wounds as well as in psoriatic lesions, both SCF and Kit are intensely expressed. Thus, it seems possible that SCF and Kit receptor interact, and this could lead to persistent mast cell activation and growth in chronic wounds and psoriasis, whereas only temporary mast cell activation is apparently needed in healing wounds.

[Temporary antibiotic-loaded cemented prosthesis for two-stage septic hip arthroplasty].

PURPOSE OF THE STUDY: During the excision period of a two-stage revision arthroplasty, the hip has a low function and an unacceptable leg length discrepancy. The goal of this study was to expose technical details in order to perform a simple articulated cement spacer which could be implanted during this period to improve hip function, to authorize partial weight bearing and to avoid leg length discrepancy. MATERIAL: This method was applied in three two-stage procedures justified because of particular immunodeficiency conditions: a 43 years old man who had bone marrow allograft and immunosuppressive therapy because of leukemia suffering of subacute septic hip arthritis; a 58 years old man suffering of diabetes and active C-hepatitis who had a septic loosening of a total hip arthroplasty (THA); a 76 years old woman suffering of diabetes who had a third septic loosening of THA. METHOD: The prosthesis was made of antibiotic-impregnated cement according to organisms antibiotic resistance. The prosthetic junction between head and diaphysis was reinforced with a tibial plate. Prosthetic shape was identical to the one of femoral broaches inserted in the femur after prosthetic and cement removal. The broach size was chosen when mechanical stability in the femur was obtained, and avoided leg length discrepancy after trials with cups. The tibial plate was bent in order to reinforce the junction with regard to the shape of the determined broach. Two doses of antibiotic-impregnated cement were mixed and molded with hands, then the plate was incorporated at the appropriate location, finally the broach was applied on this composite and cement in excess was removed before polymerisation. For prosthetic head, two options were available: to mold the cephalic zone of the cement at the patient acetabulum diameter with a soft aluminium cup previously molded in the acetabulum; to mold the cement cephalic zone with a trial cup in order to obtain a 22 or 28 ball. For this last option, a third dose of antibiotic-impregnated cement was prepared and placed in the acetabulum, a trial femoral head was applied in it to mold the location for the 22 or 28 prosthetic head. Before insertion, a collar was applied on the stem to prevent migration. Active mobilization was encouraged, and partial weight-bearing authorized. RESULTS: The mean range of hip flexion during period was 60 degrees. The patients were discharged approximatively 12 days after the first stage. Two patients had effective painless partial weight-bearing. The second stage was performed six weeks later on the average. The second procedure was easier than the second stage of a conventional two-stage procedure because of: easy and low hemorrhagic dissection authorized by the prosthesis; low difficulties with soft tissue tension as the prosthesis prevents leg length discrepancy; preservation of the articular space which prevents soft tissue sacrifice during the second stage. CONCLUSION: This simple technique is effective to prevent complications related to the excision period of a two-stage hip revision arthroplasty. Likewise, the economical aspect (short delay of hospitalisation, quick functional recovery) should be considered when compared with the excision period of a conventional two-stage procedure.

Transcatheter patch correction of secundum atrial septal defects.

The efficacy and safety of the transcatheter patch (TP) correction of a secundum atrial septal defect (ASD) was studied acutely and on short-term follow-up in 20 patients, successfully implanted with the device. TPs are made of polyurethane foam and require temporary balloon catheter immobilization on the atrial septum for 48 hours. Eighteen patients were not suitable for disk-device repair. The patient median age and ASD diameter were 37 years and 26 mm, respectively. Eighteen patients had immediate effective ASD occlusion; 2 patients had significant residual shunts. Premature leaks of the supportive balloons were responsible for the residual shunts. One of the patients with residual shunt received a second patch 6 months later with full occlusion. All patients with implants were doing well up to 24 months after implantation. Existing symptoms improved although residual shunts remained; septal anatomy was normalized, with the patched area becoming progressively indistinguishable from the rest of the septum. In conclusion, TP occlusion of secundum ASD is feasible and effective even for defects unsuitable for disk-device repair. The method appears safe acutely and on short-term follow-up, with symptomatic improvement and normalization of septal anatomy.
