RESUMO

We describe the unusual case of a female patient with a history of two mature teratomas non-correlated in terms of location and occurrence. A 12-year-old girl presented at our consultation as a result of a growing tumor in the hypogastric region, with no further clinical signs. She had undergone surgery neonatally due to a mature cystic sacrococcygeal teratoma, which was fully removed. No clinical sequelae were noted and no additional treatment was required over a 10-year follow-up. Radiological examination showed a large 20 × 12 × 18 cm cystic mass extending from the pelvic region to the lower hemiabdomen, associated with two similar small formations adjacent to the right ovary. Tumor markers were negative, and a laparoscopic right salpingoophorectomy was carried out, with an excellent postoperative progression. Pathological examination revealed it was, again, a mature cystic teratoma. The genetic study ruled out causation in this respect.


Describimos el inusual caso de una paciente con antecedente de dos teratomas maduros no relacionados en cuanto a su localización y debut. Una niña de 12 años consultó por la aparición de una tumoración en la región hipogástrica de crecimiento progresivo sin otra clínica asociada. Había sido intervenida por un teratoma quístico maduro sacrococcígeo en el periodo neonatal con su extirpación completa y, ausencia secuelas clínicas y tratamiento adicional durante diez años de seguimiento posterior. Los exámenes radiológicos mostraron una gran masa quística de 20 × 12 × 18 cm que se extendía entre la región pélvica y el hemiabdomen inferior, acompañada por otras dos pequeñas formaciones similares adyacentes al ovario derecho. Los marcadores tumorales resultaron negativos y se llevó a cabo una salpingooforectomía derecha laparoscópica con una excelente evolución postoperatoria. El examen histopatológico, de nuevo, informó la lesión como teratoma quístico maduro. El estudio genético descartó una posible causalidad en este ámbito.

RESUMO

Ionizing radiation may interfere with electric components of pacemakers or implantable cardioverter-defibrillators. The type, severity and extent of radiation damage to pacemakers, have previously been shown to depend on the total dose and dose rate. Over 300,000 new cancer cases are treated yearly in France, among which 60% are irradiated in the course of their disease. One among 400 of these patients has an implanted pacemaker or defibrillator. The incidence of pacemaker and implanted cardioverter defribillator increases in an ageing population. The oncologic prognosis must be weighted against the cardiologic prognosis in a multidisciplinary and transversal setting. Innovative irradiation techniques and technological sophistications of pacemakers and implantable cardioverter-defibrillators (with the introduction of more radiosensitive complementary metal-oxide-semiconductors since 1970) have potentially changed the tolerance profiles. This review of the literature studied the geometric, dosimetric and radiobiological characteristics of the radiation beams for high energy photons, stereotactic irradiation, protontherapy. Standardized protocols and radiotherapy optimization (particle, treatment fields, energy) are advisable in order to improve patient management during radiotherapy and prolonged monitoring is necessary following radiation therapy. The dose received at the pacemaker/heart should be calculated. The threshold for the cumulated dose to the pacemaker/implantable cardioverter-defibrillator (2 to 5 Gy depending on the brand), the necessity to remove/displace the device based on the dose-volume histogram on dosimetry, as well as the use of lead shielding and magnet are discussed.

RESUMO

BACKGROUND: Combining bevacizumab with platinum-based chemotherapy significantly improves survival for patients with advanced non-squamous non-small cell lung cancer. The objective of this study was to assess the proportion of patients who could receive this combined therapy. METHODS: This was a retrospective single centre analysis of patients treated between 2007 and 2008. Exclusion criteria for bevacizumab included: squamous cell carcinoma, contraindication to platinum-based chemotherapy, uncontrolled hypertension, haemoptysis superior to 2.5 mL, recent surgery, and/or tomodensitometric criteria after independent review by two radiologists (contact with a proximal vessel, tracheobronchial involvement, cavitation). Cardiovascular diseases and central tumour location were not systematically considered as contraindications. RESULTS: Among 194 patients analysed, 21 (10.8%) to 35 (18%) patients were eligible for bevacizumab, whether or not cardiovascular diseases and central tumour location were considered as contraindications. The kappa coefficient was 0.49. CONCLUSION: Even though the proportion of patients who can receive chemotherapy plus bevacizumab may vary according to the eligibility criteria chosen and the interpretation of the CT scan, it is unlikely to exceed 25% of patients in daily practice.

RESUMO

OBJECTIVE: Dental erosion has been considered an extraesophageal manifestation of gastro-oesophageal reflux disease, but few reports have studied the relationship between this disease and other periodontal or dental lesions. The aim of this study was to investigate the prevalence of dental and periodontal lesions in patients with gastro-oesophageal reflux disease. PATIENTS AND METHODS: A total of 253 subjects were prospectively studied between April 1998 and May 2000. Two study groups were established: 181 patients with gastro-oesophageal reflux disease and 72 healthy volunteers. Clinical assessment, including body mass index and consumption of tobacco and alcohol, was performed in all subjects, as well as a dental and periodontal examination performed by a dentist physician, blind as to the diagnosis of subjects. Parameters evaluated were: (a) presence and number of dental erosion, location and severity, according to the Eccles and Jenkins index [Prosthet Dent 1979;42:649-53], modified by Hattab [Int J Prosthes 2000;13:101-71; (b) assessment of dental condition by means of the CAO index; and (c) periodontal status analysed by the plaque index, the haemorrhage index, and gingival recessions. RESULTS: Clinical parameters were similar in both groups (p > 0.05). Age was statistically associated with the CAO index, presence of dental erosion, and gingival recession (p < 0.001, Student's t-test). Compared with the control group, the percentage of dental erosion was significantly higher in the gastro-oesophageal reflux disease group (12.5 vs. 47.5%, p < 0.001, chi2-test), as was the number and severity of dental erosions (p < 0.001, Student's t-test). Location of dental erosion was significantly different between groups. Age was not statistically related to either the amount or severity of dental erosion. CAO and periodontal indices were similarly distributed between groups. CONCLUSIONS: Dental erosion may even be considered as an extraesophageal manifestation of gastro-oesophageal reflux disease. The fact that the prevalence of caries and periodontal lesions is similar in patients with gastro-oesophageal reflux disease and in healthy volunteers suggests a lack of relationship with gastro-oesophageal reflux disease.

RESUMO

UNLABELLED: PURPOSE/MATERIAL AND METHOD: To report a case of macular translocation surgery in a myopic patient with a phakic intraocular lens, which developed subfoveal choroidal neovascularization. RESULTS: A 45 year-old woman wearing a phakic intraocular lens to correct a high myopia presented a 0.3 visual acuity because of subfoveal choroidal neovascularization. Peripheral retina had been treated by argon laser for lattice degeneration. Limited macular translocation was performed. Chorioscleral infolding was created by a circular scleral buckle. Her visual acuity, six months after surgery became 0.7. CONCLUSION: This report shows the feasibility of the use of limited macular translocation for the management of high myopic eyes with phakic intraocular lenses, in patients who suffer from subfoveal choroidal neovascularization.

RESUMO

The presence of the human T-cell leukemia virus (HTLV) in Dominican blood donors and patients with tropical spastic paraparesis (TSP) was first detected in 1987. To define further the seroprevalence in the country, nearly 4,000 samples from high- and low-risk populations, as well as patients with neurological disease and with leukemia or lymphoma were tested for HTLV antibodies. A 1-2% seropositivity rate was found among the low-risk population, a 2-5% in the high-risk, and at least 87% in those with TSP. A few patients with malignancy also had antibodies to HTLV. An increase in seropositivity with age and a predominance of female seropositive individuals were found. Infectious virus was isolated from TSP patients, prostitutes, and family members of index patients. These data indicate the substantial level of HTLV infection in another Caribbean country and its relation to neurologic disease.
