Coordination between a district hospital and a reference hospital: evaluation of chest disease care models

Specialised medical care at district hospitals has not been thoroughly defined. Respiratory care data from 2008 in Barbanza and Cee hospitals (Galicia, Spain), were analysed to evaluate different approaches, as they are both similar. Barbanza hospital has a chest diseases clinic run by specialist doctors from the reference hospital three days per week, while Cee hospital is operated by the staff on site. In both cases hospitalisation is the responsibility of the Internal Medicine department. Data was provided by the administrative departments of each hospital and the regional government. Average CDM4 stays were similar for both district hospitals; however, they were lower than in the reference hospital. Charlson scores and re-admissions a month after discharge were similar in both. Barbanza's hospital carried out more functional explorations, both at the centre (957 spirometries vs 21; P<.0001) and at the reference hospital (214 volume/diffusion tests vs 99; P<.001). CPAP treatments were more prevalent in the Barbanza area (3.9 vs 2/1,000 habitants; P<.0001). No differences were found in oxygen therapy and home mechanical ventilation. Mortality due to respiratory disease in 2007 was similar in both regions. Data suggests that in a district hospital scheme supported by chest disease consultants and outpatient clinics gives easier access to specialised, comprehensive and probably, higher quality care than district hospitals without them.     

How we approach conservative treatment of retinoblastoma in South America in the era of local ocular treatments: A consensus of the Grupo America Latina de Oncologia Pediatrica (GALOP)

Local therapies are increasingly used for ocular preservation in retinoblastoma. In middle-income countries, these techniques pose specific challenges mostly related to more advanced disease at diagnosis. The Grupo de America Latina de Oncología Pediátrica (GALOP) developed a consensus document for the management of conservative therapy for retinoblastoma. Intra-arterial chemotherapy (OAC) is the preferred therapy, except for those with less advanced disease or age younger than 6 months. OAC allowed for a reduction in the use of external beam radiotherapy in our setting. Intravitreal chemotherapy is the preferred treatment for vitreous seeding. Enucleation is the treatment of choice for eyes with advanced disease.     

Experience with chemoreduction and focal therapy for intraocular retinoblastoma in a developing country

BACKGROUND: Chemoreduction is used for the treatment of retinoblastoma in industrialized nations; however, there are fewer data from developing countries. Before the implementation of this program, radiotherapy was used in almost all preserved eyes. METHODS: Retrospective evaluation from 1995 to 2001 at the Hospital Garrahan (Argentina). Carboplatin 18.7 mg/kg/day 1 and vincristine (0.05 mg/kg/day 1) were offered to patients with Reese-Ellsworth (RE) groups I-III and all unilateral cases. Etoposide (3.3 mg/kg/day 1 and 2) was added for groups IV and V. The number of cycles was tailored according to response. RESULTS: Fifty-eight patients (78 eyes) were evaluated (39 bilateral, 19 unilateral). With a median follow-up of 47 months, 40 patients had unilateral enucleation, 14 were not enucleated, and 4 had bilateral enucleation. Nineteen patients had unilateral initial enucleation. Eye preservation at 5 years was: RE groups I-III (n = 24 eyes), 0.9 (SE: 0.095) IV-V (n = 54), 0.45 (SE 0.07). Patients received a median of four cycles of chemotherapy. Acute toxicity was mild. External beam radiotherapy was avoided in 41% of eyes with groups I-III. Etoposide was avoided in 24 patients. Two patients died of metastasis. No secondary malignancy occurred. CONCLUSIONS: Compared to our previous experience, eye preservation was better and even though less radiotherapy was used, it was prescribed more often than currently recommended in eyes with less advanced disease because of limited availability of sophisticated local therapy.     

Retinoblastoma with low risk for extraocular relapse

Objective: To define a subgroup of patients with retino-blastoma and low risk of extraocular relapse through histopathological and clinical variables. Patients and methods: Inclusion criteria consisted of stage I (intraocular disease), stage IIb1 (without concomitant choroid and/or scleral invasion), and nonenucleated patients (according to the Grabowski-Abramson classification). A total of 112 consecutive patients admitted to Hospital JP Garrahan from 1987 to 1997 were evaluable. Treatment included enucleation or local therapy and no chemotherapy. Results: Forty-one patients had stage Ia (intraretinal), 8 stage Ib (prelaminar optic nerve invasion), 40 stage Ic (uveal invasion), and 12 stage IIb1 (postlaminar optic nerve invasion and cut end free of tumor). Eleven patients had neither eye enucleated. Median follow-up was 60 months. Only two events occurred: one patient had progressive disease in the contralateral globe and died of CNS metastasis and another had an orbital relapse that was successfully treated. Both had choroidal invasion. Five-year pEFS and pOS were 0.97 and 0.98, respectively. Neither length of the optic nerve stump, tumor size, anterior chamber invasion, degree of differentiation, nor degree of ocular coat invasion correlated with increased risk of metastasis. Conclusions: A subset of patients with retinoblastoma with low risk of relapse can be determined using histopathological evaluation of the invasion of ocular coats. Adjuvant chemotherapy is not warranted for patients with intraretinal extension and prelaminar optic nerve invasion. It is also probable that those patients with isolated choroidal invasion and those with postlaminar optic nerve extension with surgical margins clear of tumor do not need chemotherapy.     

Non-alcoholic steatohepatitis induced by fast weight loss during the use of intragastric balloon--a case report

Obesity is a chronic disease that has been considered an epidemic nowadays. It is associated to much co-morbidity, such as non-alcoholic fatty liver disease (NAFLD) and its complication, steatohepatitis. We report a case of a 58-year-old obese patient refractory to clinical treatment who was submitted to the use of intragastric balloon (BIB), developing steatohepatitis induced by fast weight loss.     

Rapid Identification of Pathogenic Bacteria by means of TwoConservative Gene Loci′ Specific PCR-CE-RFLP

Molecular diagnosis is playing an increasingly importantrole in the rapid detection and identification of pathogenicorganisms in clinical samples. The genetic variation of ri bosomal genes in bacteria offers an alternative chance forthe detection and identification of these organisms. TherRNA genetic locus, rrn, is found in all prokaryotic or ganisms, and is highly conservative, although its relativelystable variation is found frequently in different bacteria.The utility of this lo…     

Combination raltitrexed (Tomudex(R))-oxaliplatin: a step forward in the struggle against mesothelioma? The Institut Gustave Roussy experience with chemotherapy and chemo-immunotherapy in mesothelioma

The aim of this study was to review the experience of the Institut Gustave Roussy in 163 patients with malignant mesothelioma over a 9-year period. Data from seven consecutive prospective trials, four of chemo-immunotherapy and three of chemotherapy were reviewed. The rationale, methods and results of these trials are summarised and discussed. 98 patients were included in four phase II trials of chemo-immunotherapy whose common denominator was a combination of cisplatin and alpha-interferon. The response rate ranged from 15% to 40%. High-dose weekly cisplatin combined with alpha-interferon yielded the highest response rate but the toxicity of this regimen was considered unacceptable. Neither higher doses of alpha-interferon or the addition of mitomycin C or interleukin-2 to the regimen were able to enhance the activity of this combination. 18 patients were included in a paclitaxel-cisplatin phase II trial. The response rate was only 6% (95% confidence interval (CI): 0-24) and toxicity was also significant. This regimen was, therefore, considered ineffective. Of 17 patients with mesothelioma included in a phase I trial that combined raltitrexed and oxaliplatin, 6 (35%) obtained a partial response. Responses were seen even in cisplatin-refractory mesothelioma. Preliminary results of a subsequent ongoing phase II trial using raltitrexed (3 mg/m(2)) and oxaliplatin (130 mg/m(2)) have confirmed this promising activity with a 30% (9/30) response rate (95% CI: 15-49). The tolerance of this outpatient regimen is acceptable (no significant haematological toxicity and no alopecia) and compares favourably with that of our previous regimens. The final results concerning response and survival are required to confirm the efficacy of this combination. The preliminary results of two studies suggest promising activity with the combination of raltitrexed-oxaliplatin in malignant mesothelioma. The efficacy/toxicity ratio of this combination compares favourably with that of our previous chemotherapy and chemo-immunotherapy regimens.
