Rehabilitation and exercise oncology program: translating research into a model of care.

INTRODUCTION: The Rehabilitation and Exercise Oncology model of care (ActivOnco) was established to optimize cancer survivorship through exercise prescription and active lifestyle promotion, providing a transition of care from hospital to community. Patients having any cancer diagnosis, stage of disease, and treatment were eligible for evaluation and exercise prescription upon deterioration of performance status. The team of professionals included hospital-based physiotherapists proactively screening for rehabilitation needs, loss of functional independence, and exercise eligibility, plus exercise specialists in a community-based Wellness Centre to provide follow-up or direct access for post-treatment or non-complex patients. METHODS: From January 2011 to December 2015, the hospital team assessed 1635 patients representing all major cancer sites, and the Wellness Centre team evaluated and prescribed exercise for 1066 participants. Primary interventions provided were education about fatigue management, physical activity promotion, exercise prescription, fracture risk reduction, referral to specialized follow-up services (for example, occupational therapy, lymphedema clinic), and coordination for mobility aids and paratransit services. RESULTS AND CONCLUSIONS: Implementation of the ActivOnco model of care showed that exercise alone is not a panacea for all functional deterioration associated with the cancer trajectory and its treatment. However, screening to identify rehabilitation needs combined with exercise prescription can effectively improve the quality of survivorship in cancer patients. Program developments are limited by the cost of human resources, lack of hospital-based physical resources, and lack of public funding, all of which significantly limit the scope and development of appropriate services.

Staged laparoscopic-assisted endorectal pull-through for long segment Hirschprung's disease and total colonic aganglionosis.

AIM: Recently laparoscopic endorectal pull-through (LERPT) has been widely performed for treatment of Hirschsprung's disease (HD) as a one stage procedure. In long segment aganglionosis (LSA) and in case of total colonic aganglionosis (TCA) a staged procedure can be preferred. The authors report their experience in the staged LERPT for LSA and TCA. METHODS: In the last five years we treated 4 infants (3 male, 1 female) with LSA and TCA. The mean age at presentation was 40 days (2-110 days). In 3 patients we performed in the first step rectal biopsies, multiple laparoscopic biopsies and stoma. In one case ­ presenting as small bowel obstruction - we performed an emergency laparotomy for ileostomy and biopsies of the bowel. Histology showed 2 left colon aganglionosis (LCA) and 2 TCA. The LERPT was performed at a main age of 10 months. After stoma closure the LERPT was performed according to Georgeson's technique. RESULTS: There were no intraoperative complications. The patient with previous laparotomy needed conversion because of the abdominal adhesions. The two infants with LCA had preoperative and recurrent postoperative enterocolitis. In one case a successful posterior anorectal myectomy was performed. At follow up the children present constipation. The patient with TCA undergoing to LERPT presents a good frequency of defecation. CONCLUSION: Our experience, although on limited series, shows that staged minimally invasive surgical treatment can be safely performed in the LSA and TCA, but conversion can be necessary especially in case of previous laparotomy.

One-trocar transumbilical laparoscopic-assisted management of Meckel's diverticulum in children.

PURPOSE: Transumbilical laparoscopic-assisted intestinal surgery using only "one trocar" is a very minimal invasive procedure. The authors present their experience for the management of Meckel's diverticulum. MATERIALS AND METHODS: Between January 2001 and December 2004, 9 transumbilical laparoscopic-assisted procedures were performed for Meckel's diverticulum. The median age of the patients was 6.1 years (range, 6 months-13.6 years). Six patients were admitted for intestinal bleeding and technetium-99m pertechnetate scan was positive in 3. Three patients had recurrent abdominal pain and abdominal ultrasound scan showed a cystlike structure. An intraumbilical Hasson 10-mm trocar was inserted in an open fashion. Using a 10-mm operative laparoscope, the terminal ileum was grasped with an atraumatic instrument and exteriorized through the umbilicus. Ileal exploration and treatment were performed extracorporeally. RESULTS: Meckel's diverticulum was identified in 8 patients and ileal duplication in 1 patient: intestinal resection/anastomosis (n = 7) or excision of diverticulum (n = 2) was performed. There were no operative complications. Median hospital stay was 4 days (range, 3-7 days). At a median followup of 24 months (range, 3-51 months), all patients are asymptomatic. CONCLUSION: Our results indicate that the one trocar transumbilical laparoscopic-assisted procedure is safe and effective for the diagnosis and treatment of Meckel's diverticulum, with excellent cosmetic results.

Thoracoscopic surgery in the management of pediatric malignancies: a multicentric survey of the Italian Society of Videosurgery in Infancy.

BACKGROUND: Few reports have elucidated the role of minimally invasive surgery (MIS) for pediatric malignancies. This study aimed to review the results of a multicenter study on the management of thoracic tumors in children using MIS. METHODS: A 5-year retrospective review of all MIS procedures for the treatment of pediatric malignancies performed in seven centers belonging to the Italian Society of Videosurgey in Infancy is reported. The data from 145 pediatric oncologic patients (80 girls and 65 boys) ages 30 days to 17 years (median, 7.2 years) were analyzed. Of the procedures performed, 87 were laparoscopies (60%), 55 were thoracoscopies (38%), and 3 were lumboscopies (2%). This study focused only on the results of the 55 thoracoscopic procedures performed for diagnostic purposes in 19 cases (34.6%) and for therapeutic purposes in 36 cases (65.4%). RESULTS: The duration of surgery was 15 to 180 min (median, 65 min). Metastasectomies were performed for various etiologies in 31 of the 55 cases. Of the 55 patients, 5 underwent resection of a mediastinal tumor, and 19 underwent a diagnostic thoracoscopy. During a mean follow-up period of 25.6 months, 2 (3.6%) of the 55 patients experienced perioperative complications. CONCLUSIONS: The role of MIS in tumor resection for children is currently limited, but may be used in individual cases when the preoperative workup shows it to be feasible. Its indication is strictly dependent on the thoracoscopic experience of the surgeon and the tumor site for preoperative imaging techniques. When the indication for thoracoscopy is correct, this approach has high therapeutic applicability (65.4% in our series). Our preliminary experience shows that careful patient selection and an appropriate level of technical skill make thoracoscopy a reasonable and safe option for the treatment of pediatric malignancies.

Italian multicentric survey on laparoscopic spleen surgery in the pediatric population.

BACKGROUND: Some technical aspects of laparoscopic spleen surgery still are debated, although efforts have been made to standardize them. The position of the patient, the approach to the spleen, vessel identification and division, and spleen extraction can vary from center to center. METHODS: This retrospective muticentric study led by the Società Italiana di Videochirurgia Infantile (SIVI) examined indications, surgical details, and complications of laparoscopic spleen surgery in the pediatric population during a 5-year period. RESULTS: The study period from January 1999 to December 2003 (5 years) involved nine centers and included 85 patients with a mean age of 10 years (range, 2-17 years). Hypersplenism or severe hemolysis in cases of hematologic disorders represented the most important indications. More than 90% of the patients underwent total laparoscopic splenectomy. Specific technical details from each center were collected. Intraoperative complications occurred in 19% of the patients (hemorrhage in 8% and technical problems in 14%), and 6% of the patients required conversion to the open approach. No deaths occurred, and no reoperations were required. Postoperative complications were experienced by 2% of the patients. CONCLUSION: Laparoscopic spleen surgery is safe, reliable, and effective in the pediatric population. On the basis of the results, some technical details for laparoscopic spleen surgery can be suggested. The patient is preferably kept supine or lateral, approaching the spleen anteriorly. Moreover, the ilar vessels should be identified selectively and individually, with initial artery division performed to achieve spleen shrinking. Any hemostatic device proved to be effective in experienced hands. Once freed, the spleen is preferably extracted via a suprapubic cosmetic transverse incision (faster, easier, and safer), although a bag can be used. Finally, the size of the spleen does not represent a contraindication for a trained and experienced surgeon. Nevertheless, this parameter must be considered when laparoscopic spleen surgery is planned.

Gamete donation and anonymity: disclosure to children conceived with donor gametes should be optional.

To force potential parents to tell their child of his/her genetic origin as a requirement for admission into an infertility programme is both wrong and discriminatory. In addition, comparing the practice of using donor gametes to conceive a child with adoption is incorrect for a number of reasons. In this article we make the argument that mandatory disclosure is both inappropriate and intrusive, and the presently available data do not justify a rigid position. Furthermore, no reasonable, practical system can be envisaged to guarantee compliance with mandatory disclosure. Although it is entirely reasonable at the time of consultation to encourage couples to consider their positions and obtain a mutual agreement on their future intent prior to treatment, the final decision on this should be a matter of free choice within the context of the couple's own value system.

Results and complications of laparoscopic surgery for pediatric varicocele.

BACKGROUND: The aim of this study was to evaluate the results and complications of laparoscopic varicocelectomy in children. METHODS: Over a 36-month period, 211 children underwent laparoscopic treatment of varicocele. Their ages ranged between 6 and 17 years; the varicocele was located on the left side in 209 cases (99.1%) and was bilateral in 2 (0.9%). In 195 patients the laparoscopic transperitoneal approach was used and in 16 retroperitoneoscopy was used. Thirty children (14.2%) underwent ligation of the veins alone, and 181 (85.8%) underwent ligation of testicular veins and artery. In 15 (7.1%) cases an additional procedure was applied during the same operation. RESULTS: Average operating time was 30 minutes and hospitalization about 24 hours. At an average follow-up of 26 months, there were 19 (9%) postoperative complications: 14 children had a left hydrocele, 3 children a scrotal emphysema, and 2 an umbilical granuloma. There were 5 recurrences of varicocele in our series: 2 (2 of 30, 6.6%) after the Ivanissevitch procedure, and 3 (3 of 181, 1.6%) after Palomo's. Testicular atrophy did not occur in any patient of this series. CONCLUSIONS: This preliminary experience shows that the results of the laparoscopic approach are comparable to those of the open approach. The ligation of testicular veins and artery is preferable to the ligation of the testicular veins alone. Hydrocele seems to be the most frequent postoperative complication and a potential problem, especially in children operated on with the Palomo procedure.

One-trocar surgery: a less invasive videosurgical approach in childhood.

BACKGROUND/PURPOSE: Laparoscopic techniques and instruments are evolving to lessen the invasiveness of this surgical approach. The authors present their experience with the videosurgical approach using only 1 trocar. METHODS: Between October 1997 and January 2000 the authors performed 59 videosurgical procedures using a 1-trocar approach (mean age, 11.5 years; range, 4 to 18 years). A 10-mm Hasson trocar was inserted in an "open" fashion either through the umbilicus (laparoscopy) or below the apex of the 12th rib (retroperitoneoscopy). An operative laparoscope was used in all cases. The operations were 18 retroperitoneoscopic Palomo varicocelectomies, 1 retroperitoneoscopic renal biopsy, 38 appendectomies, and 2 ileal resections (Meckel's diverticulum, duplication cyst). For appendectomies and ileal resections, the corresponding intestinal loop was grasped and exteriorized through the umbilicus to perform conventional surgery. RESULTS: Mean operating time was 50.9 minutes (range, 30 to 120) for laparoscopies and 44 minutes (range, 15 to 80) for retroperitoneoscopy. There were 11 conversions (8 appendectomies, 3 varicocelectomies) and no postoperative complications. CONCLUSIONS: "One-trocar surgery" is safe, effective, and fast with a low complication rate and excellent cosmetic results. The authors believe it is the least invasive as well as the most effective approach in the treatment of varicocele, appendicitis, and selected intestinal diseases.

The fallopian tube and reproductive health.

The fallopian tube is the essential link between the ovary and the uterus. Its transport mechanisms are now reasonably well understood and include orderly ovum transfer by the fimbria, and ovum/preembryo retention, with transport to the uterus on the third postovulatory day. Sperm/tube interaction ensures a reservoir and storage/activation system at the tubal isthmus. Ovum/tube interaction is driven by the HCO3 ion in the tubal secretions, which also supply pyruvate and other essential substances to the preembryo. Tubal function may be impaired/destroyed by salpingitis, a peritubal disease resulting from ruptured appendix, endometriosis, and ectopic pregnancy (often the result of prior tubal damage with partial occlusion or luminal adhesions). Prophylactic measures include counseling the patient on how to avoid sexually transmitted disease or inhibition of upward ascent of bacteria, and, in the case of ectopic pregnancy, how to use the most efficient contraceptive measures. The least intrusive transfer methods are helpful in avoiding tubal pregnancy following embryo transfer after in vitro fertilization, and results are improved by pretreatment removal of hydrosalpinges. Among adolescents, efforts should be made to preserve tubal function and to increase awareness of the importance of avoiding tubal disease with an eye to preserving future reproductive capacity.

Bronchopulmonary segmental lavage with Surfaxin (KL(4)-surfactant) for acute respiratory distress syndrome.

We performed a trial to assess the safety and tolerability of sequential bronchopulmonary segmental lavage with a dilute synthetic surfactant (Surfaxin) in 12 adults with ARDS. Patients received one of three dosing regimens in which aliquots of Surfaxin were administered via a wedged bronchoscope to each of the 19 bronchopulmonary segments. Suctioning was performed 10-30 s after instillation of individual aliquots. Group 1 patients (n = 3) received one 30-ml aliquot of a 2.5-mg/ml concentration of Surfaxin in each segment, followed by a second 30-ml aliquot with a 10-mg/ml concentration. Group 2 patients (n = 4) received two 30-ml aliquots of the 2.5-mg/ml concentration followed by a third lavage with the 10-mg/ml concentration. Group 3 patients (n = 5) received therapy identical to that received by patients in Group 2 and were eligible for repeat dosing 6 to 24 h later. All patients tolerated the procedure. There were no serious adverse experiences ascribed to either the procedure or the surfactant. In the 96 h after treatment initiation, FI(O(2)) decreased from 0.80 to 0.52 and PEEP decreased from 10.3 to 7.6 cm H(2)O. Bronchoscopic "cleansing" of the lungs with dilute Surfaxin may offer a safe and feasible approach to improving outcomes in patients with ARDS.

Efficacy of superovulation and intrauterine insemination in the treatment of infertility. National Cooperative Reproductive Medicine Network.

BACKGROUND: Induction of superovulation with gonadotropins and intrauterine insemination are frequently used to treat infertility. We conducted a large, randomized, controlled clinical trial of these treatments. METHODS: We studied 932 couples in which the woman had no identifiable infertility factor and the man had motile sperm. The couples were randomly assigned to receive intracervical insemination, intrauterine insemination, superovulation and intracervical insemination, or superovulation and intrauterine insemination. Treatment continued for four cycles unless pregnancy was achieved. RESULTS: The 231 couples in the group treated with superovulation and intrauterine insemination had a higher rate of pregnancy (33 percent) than the 234 couples in the intrauterine-insemination group (18 percent), the 234 couples in the group treated with superovulation and intracervical insemination (19 percent), or the 233 couples in the intracervical-insemination group (10 percent). Stratified, discrete-time Cox proportional-hazards analysis showed that the couples in the group treated with superovulation and intrauterine insemination were 3.2 times as likely to become pregnant as those in the intracervical-insemination group (95 percent confidence interval, 2.0 to 5.3) and 1.7 times as likely as those in the intrauterine-insemination group (95 percent confidence interval, 1.2 to 2.6). The couples in the intrauterine-insemination group and in the group treated with superovulation and intracervical insemination were nearly twice as likely to conceive as those in the intracervical-insemination group. CONCLUSIONS: Among infertile couples, treatment with induction of superovulation and intrauterine insemination is three times as likely to result in pregnancy as is intracervical insemination and twice as likely to result in pregnancy as is treatment with either superovulation and intracervical insemination or intrauterine insemination alone.

[Flurbiprofen collutory in oral surgical pathology]. / Flurbiprofen collutorio nella patologia chirurgica orale.

This study was carried out in a group of 40 patients (both sexes) aged between 18 and 65 years old. The following pathologies were controlled and studied using collutory flurbiprofen: aphthous stomatitis, pressure ulcer caused by badly fitted mobile prostheses, radicular residue, particularly sharp and cutting dental cusps, pre-and postoperative treatment for the diagnosis of embedded 8th. The topical use of collutory flurbiprofen enabled a rapid resolution of phlogosis and painful symptoms to be achieved. The positive results obtained using collutory flurbiprofen in the aforesaid pathologies prompted the authors to evaluate the efficacy of the product, which is still undergoing trials, also in lichen ruber planus and leukoplakia.

Effect of follicular size on oocyte retrieval, fertilization, cleavage, and embryo quality in in vitro fertilization cycles: a 6-year data collection.

OBJECTIVE: To determine the effect of follicular size, including the size of the leading follicle, on oocyte retrieval, fertilization, cleavage, and embryo quality in IVF cycles based on a large data collection. DESIGN: Retrospective analysis of 1,109 IVF cycles between 1987 and 1993 at the Hospital of the University of Pennsylvania including 606 patients ranging in age from 23 to 49 years. RESULTS: Follicles with a volume < or = 1 mL show a significantly lower oocyte recovery rate than follicles with a volume of > 1 mL. The highest recovery rate (83.5%) was found in follicles with a volume of 3 to 4 mL. Above a follicular volume of 7 mL, the oocyte recovery drops below that observed for follicles between 1 and 7 mL. Fertilization and cleavage rates were also higher in oocytes obtained from follicles > 1 mL compared with follicles < or = 1 mL. Although fertilization rates were fairly stable above volumes of 1 mL, cleavage rates continued to rise to a peak percentage of 92% with volumes between 6 and 7 mL. Leading follicle size did not have an effect on fertilization and cleavage rates of cohort oocytes. Embryo quality was not influenced significantly by follicular volume. CONCLUSION: Based on this evaluation of a large number of follicles, follicular size is a useful indicator of oocyte recovery, fertilization, and cleavage in IVF cycles. For optimal results, the follicular fluid volume in gonadotropin- and hCG-stimulated cycles should be > 1 mL, which corresponds to a follicle diameter of > 12 mm, and not larger than 7 mL (24 mm). For timing of hCG administration, the number of adequate size follicles appears to be more important than the size of the leading follicle(s).
