Limited population-based epidemiologic information is available on Ewing's sarcoma family of tumours (ESFT), a rare group of neoplasms. Several associations have been noted on a few studies but results were not consistent, except for exposure to farming among cases and their parents. Here we present the non-farm findings of a nationwide case-control study of ESFT in children and young adults in Australia. The analysis included 106 persons with confirmed ESFT and 344 population-based controls selected randomly via telephone. Information was collected by interview (84% face to face). We found a strong and significant association of ESFT with hernias, in particular hernia repaired in hospital (OR = 5.6, 95% Cl 1.3-6.4). Among other factors, there was a near doubling of risk for males, and male cases had their pubertal signs earlier (started shaving earlier) than male controls. There was also an increased risk of ESFT at higher levels of self-assessed exercise, but no other factor really stood out. For pregnancy-related factors, there was a tripling of risk for glandular fever, a doubling of risk for urinary tract infection and a near doubling of risk for X-rays during or just before pregnancy, but these estimates were not significant. In addition, there was a large number of inverse associations with medical conditions (specifically bone disorders), case exposure to medications, vaccinations and X-rays, with ultrasound during the pregnancy having the most certain effects. We conclude that, although the aetiology of ESFT remains obscure, overall there is strong evidence of an association with inguinal hernia; this can now be added to the farm-associated risk reported by others and us. The other associations reported here await replication and refinement in future studies. (C) 2003 Wiley-Liss, Inc.

A 14-year-old castrated male Rhodesian Ridgeback was presented with a history of sneezing and epistaxis. Diagnostic procedures included physical examination, regional and thoracic radiography, computed tomography and histological examination of an incisional biopsy. A multilobular osteochondrosarcoma of the hard palate with pulmonary metastases was diagnosed. Surgical resection of the primary tumour was achieved with clean margins and the defect was repaired using bilateral mucosal transposition flaps from the lips. Wound dehiscence and oesophageal stricture were postoperative complications, but these resolved with treatment. A long-term survival time of 14 months resulted, with good quality of life and function during this time.

Two dogs were presented for referral with nonpainful exophthalmia due to a retrobulbar mass. Incisional biopsies confirmed a histological diagnosis of infiltrative lipoma in both cases. Infiltrative lipomas are rare tumours of soft tissues and are invasive to adjacent tissue. Wide surgical resection is required to prevent local recurrence of the disease. Computed tomography of the head was performed in both cases to evaluate the extent of the masses and to plan surgical resection. Both dogs underwent a partial orbitectomy and were disease free 24 and 21 months later. The cosmetic appearance was good and both dogs maintained vision in the affected eyes.

The management of a large rib osteosarcoma in a two-year-old neutered male Golden Retriever is reported. The tumour was initially misdiagnosed as a chondrosarcoma following incisional biopsy. Extensive en bloc resection and chest wall reconstruction with propylene mesh was performed, and carboplatin was administered postoperatively. Approximately 270 days after surgery there was no evidence of tumour recurrence and the patient was disease free.

A 12-year-old male castrated Samoyed dog was presented with left-sided epistaxis and sneezing. Diagnostic procedures included haematology and biochemistry testing, thoracic radiography, fine needle aspiration of regional lymph nodes, CT, rhinoscopy, incisional biopsy and histopathology. Squamous cell carcinoma of the rostral nasal cavity was diagnosed, with no evidence of metastatic disease. External beam radiation was not an accessible treatment option. Complete surgical resection of the tumour would have required a larger, more disfiguring resection of nasal planum and maxilla than the owner was prepared to accept and may have been associated with an unacceptable morbidity. As an alternative, the extent of disease was reduced using a combination of carboplatin, doxorubicin and piroxicam chemotherapy. This allowed a less extensive nasal planum removal to be performed to remove residual disease with clean margins. The patient achieved a 14 month disease free interval from the time of surgery to the time of local recurrence. Survival time from diagnosis to eventual euthanasia for progressive local disease was 18 months.

Early to mid-term fetuses heal cutaneous incisional wounds without scars; however, fetal response to burn injury has not been ascertained. We present a fetal model of thermal injury and subsequent analysis of fetal and lamb response to burn injury. A reproducible deep dermal burn injury was created in the fetus by application of water at 66 degrees C for 7 seconds, and at 82 degrees C for 10 seconds to the lamb. Macroscopically, the area of fetal scald was undetectable from day 7 post injury, while all lamb scalds were readily identified and eventually healed with scarring. Using a five-point histopathology scoring system for alteration in tissue morphology, differences were detected between control and scalded skin at all stages in lamb postburn, but no difference was detected in the fetal model after day 7. There were also large differences in content of alpha-smooth muscle actin and transforming growth factor-beta 1 between control and scalded lamb and these differences were statistically significant at day 14 (P < 0.01). This novel model of fetal and lamb response to deep dermal injury indicates that the fetus heals a deep burn injury in a scarless fashion. Further elucidation of this specific fetal process of burn injury repair may lead to improved outcome for patients with burn injury.

Oncological patients are submitted to invasive exams in order to obtain an accurate diagnosis; these procedures may cause maladaptative reactions (fear, anxiety and pain). Particularly in breast cancer, the most common diagnose technique is the incisional biopsy. Most of the patients are unaware about the procedure and for that reason they may focus their thoughts on possible events such as pain, bleeding, the anesthesia, or the later surgical wound care. Anxiety and pain may provoke physiological, behavioral and emotional complications, and because of this reason, the Behavioral Medicine trained psychologist takes an active role before and after the biopsy. The aim of this study was to evaluate the effect of a cognitive-behavioral program to reduce anxiety in women submitted to incisional biopsy for the first time. There were 10 participants from the Hospital Juárez de México, Oncology service; all of them were treated as external patients. The intervention program focused in psycho-education and passive relaxation training using videos, tape-recorded instructions and pamphlets. Anxiety measures were performed using the IDARE-State inventory, and a visual-analogue scale of anxiety (EEF-A), and the measurement of blood pressure and heart rate). Data were analyzed both intrasubject and intersubject using the Wilcoxon test (p≤0.05). The results show a reduction in anxiety (as in punctuation as in ranges) besides, a reduction in the EEF-A.

Chronic postoperative pain is a common complication of inguinal hernia repair. An important Danish study revealed that 28.7% of patients undergoing hernioplasty suffered a varying degree of chronic pain, severe enough to interfere with normal daily activities in 11% of cases. The difficulty in treating this complication has led numerous surgeons to complete the surgical procedure ilioinguinal or iliohypogastric neurectomy. This method is proving effective in preventing the onset of chronic postoperative pain. We report the results obtained in patients undergoing neurectomy of the iliohypogastric nerve during anterior inguinal hernioplasty.

Se realizó un estudio clínico descriptivo en pacientes sometidos a histerectomía abdomina en el Hospital Vicente Corral Moscoso [MSP] y José Carrasco Arteaga [IESS] de la ciuda de Cuenca durante el año 1995, con el fin de averiguar la eficacia de la administración profiláctica de ampicilina + Sulbactam con una dosis de 4.5 gramos: 1.5 gramos una hora antes del acto quirúrgico, 1.5 gramos a las 6 horas a las 12 horas, en comparación con la administración de ampicilina, luego del acto quirúrgico, en dosis de 1 gramo cada 6 horas por vía venosa las primeras 24 horas y luego vía oral, durante 7 días. Para el efecto se conformaron 2 grupos de 30 pacientes cada uno, a las cuales se administró en el grupo "A" ampicilina + sulbactam, y al grupo "B" ampicilina solo luego del acto quirúrgico, como se explica anteriormente. Antes de la cirugía y hasta 72 horas luego del acto quirúrgico, como se explica anteriomente. Antes de la cirugía y hasta las 72 horas luego del acto quirúrgico se realizaron controles hematológicos Biométricos, control de signos vitales y del aspecto de la herida incisional los mismos que fueron seguidos hasta el acto día de la cirugía, Se concluyó que no existe una diferencia significativa, en cuanto a los resultados obtenidos, en los dos grupos ya que la diferencia esta en la bacteriuria asintomática encontrada en dos pacientes que recibieron ampicilina. A pesar de que existe estudios que señalan que da igual administrar o no profilaxis antibiótica, nosotros recomendamos la instauración de la misma debido a las condiciones de asepsia y antisepsia de nuestro servicio hospitalario. Recomendamos también realizar estudios comparativos entre pacientes que acuden a servicios de ginecología con diferentes calidades de atención; así como en mujeres que son sometidas a otros procedimientos ginecológicos con resolución quirúrgica, se consigna las fuentes de biliografía actualizada
