Abstract
BACKGROUND Despite a high paediatric tuberculosis (TB) burden globally, sensitive and specific diagnostic tools are lacking. In addition, no data exist on the impact of pulmonary TB on long-term child lung health in low- and middle-income countries. The prospective observational UMOYA study aims (1) to build a state-of-the-art clinical, radiological, and biological repository of well-characterised children with presumptive pulmonary TB as a platform for future studies to explore new emerging diagnostic tools and biomarkers for early diagnosis and treatment response; and (2) to investigate the short and long-term impact of pulmonary TB on lung health and quality of life in children. METHODS We will recruit up to 600 children (0-13 years) with presumptive pulmonary TB and 100 healthy controls. Recruitment started in November 2017 and is expected to continue until May 2023. Sputum and non-sputum-based samples are collected at enrolment and during follow-up in TB cases and symptomatic controls. TB treatment is started by routine care services. Intensive follow-up for 6 months will allow for TB cases to retrospectively be classified according to international consensus clinical case definitions for TB. Long-term follow-up, including imaging, comprehensive assessment of lung function and quality of life questionnaires, are done yearly up to 4 years after recruitment. DISCUSSION The UMOYA study will provide a unique platform to evaluate new emerging diagnostic tools and biomarkers for early diagnosis and treatment response and to investigate long-term outcomes of pulmonary TB and other respiratory events on lung health in children.

Abstract
INTRODUCTION Bronchoscopy can be a useful tool in children with pulmonary tuberculosis (PTB) with severe disease potentially requiring intervention or in the face of diagnostic dilemmas. The aim of this study was to determine the value of Xpert MTB/RIF assay (Xpert) on bronchoalveolar lavage (BAL) samples in children with complicated PTB. METHODS Retrospective analysis of children with clinically diagnosed PTB, who underwent routine bronchoscopy over a 5-year period at a large referral hospital. BAL and other respiratory samples were tested by microscopy, culture, and Xpert. We explored whether clinical, radiographic and bronchoscopy findings, and duration of antituberculosis treatment were associated with bacteriological confirmation. RESULTS One hundred and twelve out of one hundred and forty-six (76.7%) children (median age 16 months) were on antituberculosis treatment for a median of 10 days at the time of bronchoscopy. Overall, bacteriological confirmation was achieved in 115 (78.7%), with 101 (69.2%) detected on BAL. Of those bacteriologically confirmed on BAL, 61.4% were positive by both Xpert and culture, 34.7% only by Xpert, and 3.9% only by culture. Sensitivity and specificity of Xpert compared with culture on BAL samples for children not on antituberculosis treatment were 94.1% (95% confidence interval [CI]: 71.3, 99.8) and 68.7% (95% CI: 41.3, 89.0), respectively. CONCLUSIONS In children undergoing bronchoscopy for complicated PTB, Xpert testing of BAL had a high diagnostic yield in children already on antituberculosis treatment. Bronchoscopy should be considered if noninvasive respiratory specimens fail to confirm complicated TB.

Abstract
Dense microcircuit reconstruction techniques have begun to provide ultrafine insight into the architecture of small-scale networks. However, identifying the totality of cells belonging to such neuronal modules, the "inputs" and "outputs," remains a major challenge. Here, we present the development of nanoengineered electroporation microelectrodes (NEMs) for comprehensive manipulation of a substantial volume of neuronal tissue. Combining finite element modeling and focused ion beam milling, NEMs permit substantially higher stimulation intensities compared to conventional glass capillaries, allowing for larger volumes configurable to the geometry of the target circuit. We apply NEMs to achieve near-complete labeling of the neuronal network associated with a genetically identified olfactory glomerulus. This allows us to detect sparse higher-order features of the wiring architecture that are inaccessible to statistical labeling approaches. Thus, NEM labeling provides crucial complementary information to dense circuit reconstruction techniques. Relying solely on targeting an electrode to the region of interest and passive biophysical properties largely common across cell types, this can easily be employed anywhere in the CNS.

Abstract
Several halogenated flame retardants were detected in black kite, white stork and greater flamingo unborn eggs from Doñana Natural Space (Spain) collected in 1999, 2003, 2011 and 2013. The main components of Penta-BDE commercial mixture (BDE-47, -99 and -100) showed a decrease in the studied time interval, concurring with the ban of this mixture in the European Union (EU) in 2006. On the other hand, BDE-209, the main component of Deca-BDE mixture showed a clear trend in black kites but further monitoring is needed since its production ceased at the end of 2013. Besides, even if Dechlorane Plus (DP) was proposed by the EU as an alternative to BDE-209 no time trends were observed. Furthermore, total concentrations of PBDEs (classical FRs) are still higher than concentrations of hexabromocyclododecane (HBCD) and alternative FRs halogenated norbornenes (HNs), which are theoretically substitutes of the already banned PBDEs.

Abstract
BACKGROUND Dysplasia epiphysealis hemimelica (DEH) is a rare developmental bone disorder with hemimelic involvement of one or more epiphysis. We report on nine new cases and discuss the clinical manifestations, the value of MRI, and the results of complete and early surgical resection of these lesions. MATERIALS AND METHODS In this retrospective study, nine patients with a diagnosis of DEH were evaluated. Age at presentation ranged from 1 year to 12 years. The main complaint at diagnosis was a swelling bony mass. Angular deformities were recorded in two patients. All patients were surgically treated and followed up clinically and by imaging. Eight patients underwent excision only. RESULTS The average follow-up was 5.6 years (range, 2-10.5 years). All patients had a good outcome without related symptoms. No epiphysiodesis, angular deformity or recurrence was observed. One patient with femoral lesion involving the distal medial part of the epiphysis developed, four months after surgical excision, a calcification outside the area of total excision. This calcification did not increase in size at two years follow-up. Another patient with lateral involvement of the proximal tibial epiphysis presented a postoperative nervous complication. Spontaneous nervous recovery occurred three months after surgery. DISCUSSION MRI was useful to find a potential plane of cleavage between the epiphysis and the pathological tissue. We recommend early removing ossifications when a cleavage plane is identified. Waiting a possible complication or increasing of size does not seem logical. Of course, the treatment will be not the same if no cleavage plane is found on MRI. LEVEL OF EVIDENCE IV.

Abstract
BACKGROUND Children with complicated intrathoracic tuberculosis (TB) require rapid confirmation of TB diagnosis and of drug susceptibility to institute appropriate therapy. In a pilot study, we evaluated the feasibility and potential utility of GeneXpert (Xpert) on bronchoalveolar lavage (BAL) samples in children undergoing routine diagnostic bronchoscopy. METHODS We included children <13 years of age undergoing bronchoscopy for suspected complicated intrathoracic TB at Tygerberg Children's Hospital, October 1, 2012-May 15, 2013. A minimum of two respiratory specimens in addition to BAL were obtained from each child. In addition to fluorescent smear microscopy and automated liquid culture performed on all samples, BAL samples were analyzed by Xpert. Drug susceptibility was confirmed by GenoType(®) MTBDRplus. RESULTS Fourteen children (2 HIV positive, median age 16 months) were included. The Mantoux tuberculin skin test was positive in 11. On chest radiograph, six children had expansile pneumonia and nine had airway compression (one had both). The median duration of TB treatment before bronchoscopy was 8 days. TB was confirmed by either culture or Xpert from any sample in 11 (78%) children. Among 9/14 (64%) cases confirmed by culture, BAL Xpert was positive in 7 (78% sensitivity); in addition, Xpert confirmed 2 cases who had negative culture (14% additional diagnostic yield). Two drug resistant cases were identified: one by BAL Xpert and one from genotypic testing of a culture from gastric aspirate. All children were initiated on anti-TB treatment and responded well to therapy. CONCLUSION BAL Xpert resulted in additional diagnostic yield and also in the rapid detection of drug resistance in children with complicated intrathoracic TB. The clinical impact of this modality should be further evaluated in children.

Abstract
BACKGROUND The efficacy and safety of capecitabine and bevacizumab in elderly patients with metastatic colorectal cancer (mCRC) considered unsuitable for receiving first-line chemotherapy with an irinotecan or oxaliplatin-based combination were assessed in a phase II, open, multicentre, uncontrolled study. METHODS Treatment consisted of capecitabine 1250 mg m(-2) (or 950 mg m(-2) for patients with a creatinine clearance of 30-50 ml min(-1)) twice daily on days 1-14 and bevacizumab (7.5 mg kg(-1)) on day 1 every 3 weeks. RESULTS A total of 59 patients aged >or=70 years with mCRC were enrolled. In an intention-to-treat analysis, the overall response rate was 34%, with 71% of patients achieving disease control. Median progression-free survival and overall survival were 10.8 months and 18 months, respectively. In all, 32 patients (54%) had grade 3/4 adverse events (AEs), the most common being hand-foot syndrome (19%), diarrhoea (9%) and deep venous thrombosis (7%). Four patients died because of treatment-related AEs. A relationship was detected between creatinine clearance CONCLUSION Bevacizumab combined with capecitabine represents a valid therapeutic alternative in elderly patients considered to be unsuitable for receiving polychemotherapy.

Abstract
4119 Background: Colorectal adenocarcinoma is the most common cancer in subjects over 70 years old. New therapies have been developed but limited data about their activity are available in elderly population. Results obtained with capecitabine have shown an appropriate safety and efficacy profile in these patients. The aim of the present study is to evaluate the overall response rate in that patient's population who presents colorectal adenocarcinoma and are treated with the combination of capecitabine+BVZ. Methods: This is a multicentric, non-controlled, open label, phase II clinical trial. Capecitabine(1250mg/m2 bid, orally)+BVZ(7.5mg/kg, intravenously) treatment was administered in 3-week length cycles until disease progression. Capecitabine dose was reduced to 1000mg/m2 when the creatinine clearance was between 30 and 50ml/min. Results: A total of 59 patients were included (57.6%, male). Mean age was 76±4.1 years. ECOG status was 0–1 in 96.5 % of the patients. Activities of daily living: moderate to severe dependence and functional incapacity in 24.5% and 5.6% of the patients by Lawton and Barthel scales, respectively. Comorbidities: hypertension (61%), venous thrombosis (5.1%), cardiac disease (5.1%) and acute cerebrovascular accident history (3.4%). Metastases were detected in liver (84.7%), lung (45.8%), local/regional (18.6%) and other locations (5.1%). Mean number of cycles of capecitabine+BVZ was 6.8±6.1. Most frequent grade 3–4 toxicities observed were hand-foot-syndrome (18.6%), diarrhea (8.5%), deep venous thrombosis (6.8%), pain (5.1%) and mucositis (3.4%). Four patients died due to toxicity (mucositis, digestive hemorrhage, hematological toxicity and sepsis, respectively). Metastasis resection was performed in 10.2% of the patients. Treatment response was: 33.3% partial response and 59.0% stable disease. Median progression-free survival was 10.8 months. Conclusions: The combination capecitabine+BVZ in elderly patients appears to have a manageable safety profile and achieves promising results in terms of response rates and progression free-survival. No significant financial relationships to disclose.

Abstract
3573 Background: Preop chemoradiotherapy (CRT) with CI 5-FU is a standard of care for LAR cancer. Oral fluoropyrimidines, an attractive alternative to intravenous 5-FU, are perceived by patients as more convenient. Methods: We performed a phase II study in patients with potentially resectable tumors, localized in middle or distal rectum, ultrasonographically staged as T3 or T4 or N+ who were treated with UFT (400 mg/m2/d, 5 days a week for 5 weeks) and concomitant RT to the pelvis (45 Gy; 1.8 Gy/d over 5 weeks). Pts underwent surgery 5 to 6 weeks later followed by four cycles of 5-FU/LV (Mayo Clinic Scheme). Early end points of efficacy (pCR, downstaging, sphincter preserving surgery) and toxicity have already been reported (JCO 2004;22:3016). We now present data on secondary objectives (RFS, DFS and OS) and univariate and multivariate analysis of clinical and pathological PF. Results: 94 patients were included and complete information on 88 (94%) is availablewith a median follow-up of 5 years (60.4 months). Actuarial Kaplan-Meier DFS, RFS and OS are 61%, 66%, and 70 %. Patterns of failure are 7% pelvic and 25% distant. Univariate analysis results are shown in the table . Survival rate was also higher among patients with no or few residual disease after CRT but did not reach statistical significance. In Cox multivariate analysis both ypT and ypN are independent PF for DFS and RFS but only ypT is an independent PF for OS. Conclusions: This approach with preop UFT/RT reproduces the results that have been accomplished with 5-FU. ypT and ypN could be helpful to identify different risk groups and to select adjuvant treatments.

Abstract
BACKGROUND Fifty percent of lung cancers arise in patients over 65 years old and 30% in those over 70. The aim of this study was to evaluate response, survival and tolerability of the combination carboplatin-gemcitabine in elderly patients with advanced non-small cell lung cancer (NSCLC). METHODS Between May 1998 and December 2000, 88 patients were included. Median age was 74 (range 65-83). Treatment consisted of gemcitabine 1250 mg/m(2) (1000 mg/m(2) in the first six patients) on days 1 and 8, and carboplatin AUC=4 on day 1, every 21 days. Prognostic factors for survival were analysed. Performance status (PS) and symptoms were evaluated before and after three and six courses. RESULTS A total of 400 cycles were administered (median of four per patient). WHO grades 3-4 toxicities were: neutropenia in 13% of the cycles, thrombocytopenia and anaemia in 4.5 and 14.7% of patients in any cycle. There was one treatment-related death. According to the intent-to-treat analysis, 33 patients achieved objective response, 33 had stable disease, and 22 had treatment failure (progression in 18 patients). Median and 1 year survival were 9 months and 34%, respectively. Median time to progression was 8 months. Only disease stage and PS showed independent prognostic value. Comorbidity and PS displayed no close correlation. Symptom improvement was seen as follows: pain (61.7%), dyspnea (50%), haemoptysis (80%), anorexia (62.5%) and asthenia (61.5%). CONCLUSIONS The combination carboplatin-gemcitabine at these doses is feasible in elderly patients with advanced non-small cell lung cancer. Tolerability and toxicity are acceptable. Response rate and survival stand in the range of the most active regimens. Comorbidity and PS showed prognostic independence.

Abstract
BACKGROUND Irinotecan (CPT-11) and raltitrexed are active against advanced colorectal cancer (ACC), act through different mechanisms, and have only partially overlapping toxicity profiles. Phase I studies have shown that single-agent full doses of both drugs can be safely combined. The aim of this multicenter study was to assess the efficacy and toxicity of the combination in patients with 5-fluorouracil (5-FU)-refractory ACC. PATIENTS AND METHODS Between October 1999 and December 2000, 52 patients (31 males, 21 females) with a median age of 62 years (range 39-75) were included and received CPT-11 (350 mg/m(2) as a 60-min infusion) plus raltitrexed (3 mg/m(2) as a 15-min infusion, 1 h after CPT-11), with courses repeated every 21 days. Objective response was assessed after every three courses, and treatment maintained until tumor progression or unacceptable toxicity. RESULTS A total of 313 cycles were administered, with a median of six cycles per patient (range 1-14). Seven patients (13.5%) achieved a partial response and one a complete response (1.9%), for an overall intention-to-treat response rate of 15.4% (95% confidence interval 6.1% to 27.2%). The incidence of grade 3/4 toxicity was 23.1% for diarrhea, 21.2% for asthenia, 17.3% for neutropenia, 13.4% for emesis and 7.7% for infection. There were no treatment-related deaths. With a median follow-up of 20 months, median survival was 11.9 months and median time to progression was 4.6 months. CONCLUSIONS CPT-11 plus raltitrexed is active in patients with 5-FU-refractory ACC, at the expense of moderate toxicity.

Abstract
Currently, monotherapy is considered a valid alternative to the combination antibiotic treatments used for initial, empirical management of febrile neutropenia. The advent of new cephalosporins warrants assessment. The aim of this study was to prospectively evaluate the effectiveness of cefepime monotherapy in the treatment of cancer patients with febrile granulocytopenia (< 1000 leukocytes/muL and/or < 500 neutrophils/muL). A prospective, multicenter, nonrandomized trial was conducted. Initial treatment consisted of iv cefepime, 2 g every 8 h. If the patient was still febrile after 72 h, amikacin, vancomycin/teicoplanin, and amphotericin B were added sequentially. Response was evaluated according to EORTC criteria. One hundred twenty episodes were analyzed in 81 males and 39 females (median age, 52 yr; range, 15-83). The median leukocyte count at the time of diagnosis was 781 microL(-1) (range, 100-2600) and the median neutrophil count was 173 microL(-1) (range 0-500). The median duration of neutropenia (< 1000 neutrophils/microL) was 4.8 d (range, 3-20). Fifty-two episodes (44%) were confirmed microbiologically (42 presented as bacteremia), 31 with Gram-positive bacteria and 21 with Gram-negative bacteria, 47 (39.3%) were confirmed clinically, 16 (13.3%) were considered as probable infections, and 5 (4.2%) as doubtful infections. Protocol success was achieved in 110 episodes (91.7%), 8 (6.6%) were treatment failures, and 2 (1.7%) were not evaluable. Ninety-nine episodes (83.3%) were controlled with cefepime monotherapy, with 19 other episodes requiring additional antibiotics: amikacin in 7 (5.8%), amikacin + vancomycin/teicoplanin in 12 (10.1%). Three patients (2,5%) died during an episode of neutropenic fever. Cefepime is effective as an initial, empirical treatment of febrile neutropenia. The early addition of amikacin and/or vancomycin resolves most of the monotherapy failures, which seem somewhat lower than with other monotherapies.

Abstract
This study evaluated the biomechanical strength and bone formation in calvarial critical size bone defects covered with expanded polytetrafluoroethylene (e-PTFE) membranes in rats treated systemically with recombinant human growth hormone (rhGH). A full-thickness bone defect, 5 mm in diameter, was trephined in the central part of each parietal bone in 40 one-year-old female Wistar rats, which were randomly assigned to two groups of 20 animals each. The bone defects were covered with an exocranial and an endocranial e-PTFE membrane. From the day of operation, the rhGH-treated animals were given 2.7 mg rhGH/kg/day and the placebo-injected rats were given isotonic sodium chloride. The animals were killed 28 days after operation. The biomechanical test was performed by a punch out test procedure placing a 3.5-mm diameter steel punch in the centre of the right healed defect. After mechanical testing, the newly formed tissue inside the defect was removed and the dry and ash weights were measured. The left healed defects were used for three-dimensional (3D) reconstruction by means of micro-computer tomography (micro-CT). Ultimate load, ultimate stiffness, and energy absorption at ultimate load were significantly increased in the rhGH-treated group (P < 0.003). Also, tissue dry and ash weights were significantly augmented in the rhGH-treated group (P < 0.001). The 3D reconstruction of newly formed bone showed that there was almost twice as much bone volume present in the rhGH-treated defects compared with the placebo group. The experiment demonstrated that rhGH administration enhances bone deposition and mechanical strength of healing rat calvarial defects, covered with e-PTFE membranes.

Abstract
OBJECTIVE To analyze the long-term effect of mandibular bone as donor material in bone grafting of the alveolar process defect in patients with unilateral cleft lip and palate (UCLP), compared with iliac crest cancellous bone. METHOD During a 7-year period, 101 UCLP patients were bone grafted, 57 cases with iliac crest cancellous bone and 44 with mandibular symphyseal bone. The long-term results with an observation time of more than 4 years were analyzed with respect to marginal bone level and dental and gingival condition in the grafted area. Complications were recorded. RESULTS The bone level in the grafted area was satisfactory in both groups. Impaction of cleft-side canines was found in 35% of the patients in both groups. Patients with agenesis of the cleft side lateral incisor had significantly more impacted canines, compared with patients with a cleft-side lateral situated in the lesser maxillary segment, probably due to the fact that the lateral incisors help in guiding the canine down through the grafted area. The number of complications was scarce, although both groups demonstrated some gingival retraction with a longer crown length at the cleft side central incisor. CONCLUSION The findings of this study have changed our strategy in bone grafting. Timing of orthodontic treatment and bone grafting has been more varied depending on the position and presence of teeth in the cleft area. Bone grafting of the alveolar process is not just a local treatment of a bony defect, but in respect to the burden of treatment, bone grafting of the alveolar process has to be planned in accordance with orthodontic treatment and maxillofacial growth.

Abstract
The purposes of this investigation were to compare the clinical performance of a resin-reinforced self-cured glass ionomer cement to a standard composite resin in the direct bonding of orthodontic brackets when bonded onto: a) dry teeth and b) teeth soaked with saliva. The two bonding agents were compared using a split-mouth design. In that, both systems were used for direct bonding of stainless steel brackets in every patient. Thirty-eight consecutive patients with fixed appliances were followed for a period of 12 months. The patients were randomly divided into two groups: group A (11 patients) and group B (27 patients). In group A, the performance of 220 stainless steel brackets was evaluated: 110 brackets were bonded with GC Fuji Ortho glass ionomer cement (GC Industrial Co., Tokyo, Japan) onto dry teeth, and 110 bonded with System 1+ composite resin (Ormco Corp., Glendora, CA). In group B, the performance of 540 stainless steel brackets was evaluated: 270 brackets were bonded with GC Fuji Ortho onto teeth soaked with saliva, and 270 bonded with System 1+. In group A, GC Fuji Ortho recorded an overall failure rate (34.5%) significantly higher (p < 0.05) than System 1+ (9%) when applied onto completely dry teeth. Conversely, in group B, no statistically significant differences (p > 0.05) between the failure rates of the two bonding agents were found when GC Fuji Ortho was used on teeth soaked with saliva. It was concluded, therefore, that GC Fuji Ortho shows clinically acceptable bond strengths when bonded onto moist teeth, but not when used on dry enamel. Both bonding agents failed mostly at the enamel/adhesive interface, without causing any enamel damage.

Abstract
The purpose of this study was to compare the clinical performance of a resin-reinforced self-cured glass ionomer cement to a standard composite resin in a split mouth design, by using both systems for direct bonding of orthodontic stainless steel brackets in every patient. Forty eight patients (34 females and 14 males, of which 29 were adults > 18 years of age) with fixed appliances were followed for a mean period of 10 months (range 4-16 months). The performance of 864 stainless steel brackets was evaluated: 404 brackets were bonded with GC Fuji Ortho glass ionomer cement (GC Industrial, Tokyo, Japan) onto teeth soaked with water, and 460 were bonded with System 1+ composite resin (Ormco, Glendora, CA). System 1+ recorded an overall failure rate (18.2%) significantly higher (p < 0.05) than GC Fuji Ortho (7.9%). There were no statistically significant differences (p > 0.05) between the failure rates in the upper and lower arches with either material. Both in the upper and lower arches, System 1+ exhibited a failure rate significantly higher (p < 0.05) than GC Fuji Ortho. When the bonding performance of the six anterior teeth was compared with first and second premolars, no statistically significant differences were found (p > 0.05) between bonding agents in either arch. System 1+ exhibited a failure rate significantly higher (p < 0.05) than GC Fuji Ortho, both in the anterior and posterior segments. Both bonding agents failed mainly at the enamel-adhesive interface, without causing any damage to the enamel.

Abstract
A substantial interest exists in developing substitute materials and human recombinant bone-inducing factors to enhance bone regeneration both in the craniofacial complex and in other parts of the skeleton. A persistent problem has been to find an animal model that allows for the comparison of different osteopromotive materials. The purpose of this investigation was 1) to determine whether a 5-mm calvarial defect in adult rats fulfilled the requirements of a critical-size bone defect and 2) to discuss the use of this animal model in assessing bone repair in the craniofacial region. Bilateral full-thickness calvarial defects were trephined in the calvarial bone of 56 5- to 6-month-old Wistar rats. Except for minor amounts of bone formation limited to the margins of the defect, none of the defects revealed any signs of spontaneous bone regeneration 6 and 12 months after surgery. The full-thickness 5-mm calvarial defects thus fulfill the criteria for a critical-size bone defect. This animal model allows for an experiment with a paired design, it avoids inclusion of the sagittal suture in the osseous defect, and it thereby minimizes morbidity by reducing the risk of damaging the midsagittal sinus. An adequate experimental model has been developed to evaluate the efficiency of osteopromotive materials in the healing of bone defects in the craniomaxillofacial region.

Abstract
Several members of the bone morphogenetic protein (BMP) and transforming growth factor-beta (TGF-beta) families are molecular regulators of cartilage and bone regeneration, although their actual roles and combined interactions in skeletal repair are poorly understood. The presence of several molecular forms suggests multiple functions in vivo as well as synergistic interactions during both embryonic bone development and regeneration of cartilage and bone in postfetal life. Here we show for the first time that recombinant human transforming growth factor-beta1 (TGF-beta1) induces endochondral bone formation in extraskeletal sites of adult baboons. We also show that TGF-beta1 and recombinant human osteogenic protein-1 (OP-1, bone morphogenetic protein-7) synergize in inducing large ossicles in extraskeletal sites of the primate as early as 15 days after implantation. A single application of OP-1, in conjunction with an insoluble collagenous matrix as carrier (5, 25, and 125 microg/100 mg of carrier matrix) induced bone differentiation in the rectus abdominis of the baboon. This level of tissue induction was raised several-fold by the simultaneous addition of comparatively low doses of TGF-beta1 (0.5, 1.5, and 5 microg), which by itself induces bone formation in the rectus abdominis at doses of 5 microg/100 mg of carrier matrix. Combinations of OP-1 and TGF-beta1 yielded a 2- to 3-fold increase in cross-sectional area of the newly generated ossicles, with markedly elevated key parameters of bone formation, and corticalization of the newly formed bone by day 15, culminating in bone marrow generation by day 30. The tissue generated by the combined application of OP-1 and TGF-beta1 showed distinct morphological differences when compared with OP-1-treated specimens, with large zones of endochondral development and extensive bone marrow formation. At the doses tested, synergy was optimal at a ratio of 1:20 by weight of TGF-beta1 and OP-1, respectively. These results provide evidence for a novel function of TGF-beta1 in the primate and the scientific basis for synergistic molecular therapeutics for the rapid regeneration of cartilage and bone.

Abstract
A new measuring method is described for obtaining a proton titration curve. The curve is obtained from a microporous composite membrane, consisting of polystyrene beads in an agarose matrix, with lysozyme molecules adsorbed to the bead surface. The membrane is incorporated into a sensor system by deposition on a silicon chip with a pH-sensitive ion-sensitive field effect transistor (ISFET) located in the middle of a Ag/AgCl electrode. The actual measurement is performed by creating a stepwise change in the salt concentration of the bathing electrolyte (the ion step) and measuring the ISFET potential versus the Ag/AgCl electrode. This potential shows a transient change in the ion step, which indicates a transient pH change in the membrane. This procedure is repeated at a series of pH values. Equations are presented to calculate the proton titration curve of the membrane from the amplitude and duration of the measured transients. Measurements show qualitative agreement between the curves obtained and equilibrium titration experiments on the same system.

Abstract
The development of the nose and the growth of the midface has been followed in a pair of identical twins. One of them (twin A) had nasal septum destruction after septal haematoma and abscess at the age of 7 years, and was treated by immediate implantation of homologous septal cartilage from a tissue bank. From 7-17 years of age the growth and development of the nose and face were followed. Lateral cephalograms, photographs, acoustic rhinometry and rhinoscopy were performed. Twin B presented a normal nasal and facial growth and served as control. Twin A developed a saddle nose, an upward displacement of the anterior part of the maxilla, diminished vertical development of the nasal cavity, and a retrognathically positioned maxilla due to decreased anteroposterior maxillary growth. This case report seems to indicate that the cartilaginous nasal septum is an important factor influencing vertical and sagittal growth of the maxilla.

Abstract
OBJECTIVE Conventional cephalometry is an inexpensive and well-established method for evaluating patients with dentofacial deformities. However, patients with major deformities, and in particular asymmetric cases are difficult to evaluate by conventional cephalometry. Both two- and three-dimensional computed tomography (CT) have been proposed to alleviate some of these difficulties. Only a few studies using metallic markers have indicated 3-D CT to be a useful diagnostic method, whereas no studies have evaluated the reliability of the anatomic cephalometric points used in 3-D CT. The aim of our study therefore was to compare the reliability of anatomic cephalometric points from conventional cephalograms and 3-D CT. METHODS Nine human dry skulls were CT scanned. In addition standard lateral and frontal cephalograms were obtained. The CT scans were 3-D image reconstructed, and the cephalometric points were recorded as x, y, and z co-ordinates by two investigators. Computerized cephalometrics were performed-on the lateral and frontal cephalograms. Intra- and interindividual variations were calculated for each method and tested for statistical significance. RESULTS Lateral cephalogram measures were more reliable than 3-D CT, with interobserver variations less than 1 mm for most points compared to about 2 mm for 3-D CT. Lateral cephalometrics also showed significantly less interobserver variation for six variables. This was, however, less obvious when 3-D CT was compared to frontal cephalograms. Frontal cephalometrics showed significantly less interobserver variation for three of the investigated variables. CONCLUSIONS For standard lateral and frontal cephalometric points, there is no evidence that 3-D CT is more reliable than the conventional cephalometric methods in normal skull, and the benefit of 3-D CT cephalometric is indicated to be in the severe asymmetric craniofacial syndrome patients, as conventional cephalometrics is known to be inferior in these cases.

Abstract
BACKGROUND Analgesics can avoid postoperative pain. The aim of this study was to evaluate their prescription after abdominal surgery. PATIENTS AND METHODS Prospective study including patients who had undergone abdominal surgery in two hospitals in Barcelona, in 1993. Prescription and administration of analgesic drugs, and pain severity during the first 48 hours of the postoperative period were evaluated. RESULTS One hundred and sixty-four patients (83 men) were included. The most frequently prescribed drugs were metamizol (111; 68%), pethidine (83, 51%), and diclofenac (44; 27%). A high percentage of analgesic prescriptions on an "as needed" basis was recorded. Administered doses were lower than those recommended, and lower than those prescribed. Fifty-three percent of patients suffered significant pain during the first day. CONCLUSION A too low proportion of analgesic drugs is prescribed in a predetermined schedule, in contrast to "as needed" prescription. Opiate derivatives are underused. All analgesic drugs are prescribed at inadequate dosage. This prescription pattern is associated with a high prevalence of postoperative pain.

Abstract
Orthodontic treatment outcome is often compromised by the loss of anchorage. The forces acting on the anchorage unit have, however received surprisingly little attention, and the loss of anchorage is most frequently expressed in the sagittal occlusal relationship. The present paper discusses the interaction between vertical and sagittal components of dentofacial development, and the importance of taking vertical forces into consideration is stressed. The biological background for anchorage is reviewed, i.e., the impact on the cellular reaction of the periodontal ligament around the teeth of the anchorage unit from the orthodontic force system and from occlusion. A new rigid appliance consisting of two occlusal splints connected with transpalatal arches is introduced. The advantage of using the patient's sense of occlusion as part of anchorage by means of this appliance is demonstrated in a number of case presentations.

Abstract
The therapeutic utility of a single application of recombinant human transforming growth factor-beta (hTGF-beta) has not been previously tested in large osseous wounds in primates. Sixteen calvarial defects, 25 mm in diameter, were prepared in four adult male baboons (Papio ursinus). In each animal, three defects were treated with increasing doses of hTGF-beta 1 in conjunction with baboon insoluble collagenous bone matrix as carrier (5, 30, and 100 micrograms of hTGF-beta 1/g of matrix). The fourth defect was implanted with collagenous matrix without hTGF-beta 1 as control. Serial undecalcified sections were prepared from the specimens harvested on day 30. Islands of cartilage and endochondral osteogenesis were found in hTGF-beta 1-treated defects, irrespective of the doses used. Histomorphometry of the defect site showed no significant differences between control and hTGF-beta 1-treated specimens with regard to bone and osteoid volumes. However, analysis of the regenerated tissue in proximity to the defect margins only showed that, on average, greater amounts of bone formed in specimens that were treated with 5 and 30 micrograms of hTGF-beta 1 when compared with controls. This suggests a possible effect on osteoblastic cells originating from the periosteal and endosteal spaces of the severed calvaria. Overall, however, this difference has no therapeutic implications for the healing of large cranial wounds in primates. The present findings indicate that a single application of hTGF-beta 1, in conjunction with collagenous matrix, results in limited chondro-osteogenesis in defects of membranous bone of adult baboons.

Abstract
Bone healing plays an important role in orthognathic and craniofacial surgery. Bone tissue repair and regeneration are regulated by an array of growth and morphogenetic factors. Osteogenesis proceeds through a cascade of molecular and cellular events sequentially coordinated by members of both the bone morphogenetic protein and transforming growth factor-beta (TGF-beta) families. The efficacy of a single application of 2, 5, or 10 micrograms of recombinant human (rh) TGF-beta 1 to promote bone regeneration in 5-mm experimental calvarial defects of adult male rats was assessed histologically and histomorphometrically. The histomorphometric results of the experimental site were compared with those of the contralateral control side. Dosegroup comparisons were also performed. None of the control and experimental bone defects demonstrated complete bone closure. Limited bone regeneration was found close to the margins of the defects. A statistically significant difference in volume fraction composition (bone, osteoid, and soft tissue) was found between the 5- and 10-microgram rhTGF-beta 1-implanted and control defects. No difference was found in the 2-microgram rhTGF-beta 1-implanted group. The percentage of bone closure was statistically significantly higher in the 5-microgram rhTGF-beta 1-implanted group than in the control group. The present findings indicate that a single application of different doses of rhTGF-beta 1 does not promote clinically relevant osteogenesis in membranous calvarial bone defects in adult rats.

Abstract
Guided bone regeneration is defined as controlled stimulation of new bone formation in a bony defect, either by osteogenesis, osteoinduction, or osteoconduction, re-establishing both structural and functional characteristics. Bony defects may be found as a result of congenital anomalies, trauma, neoplasms, or infectious conditions. Such conditions are often associated with severe functional and esthetic problems. Corrective treatment is often complicated by limitations in tissue adaptations. The aim of the investigation was to compare histologically the amount of bone formed in an experimentally created parietal bone defect protected with one or two polytetrafluoroethylene membranes with a contralateral control defect. A bony defect was created bilaterally in the parietal bone lateral to the sagittal suture in 29 6-month-old male Wistar rats. The animals were divided into two groups: (1) In the double membrane group (n = 9), the left experimental bone defect was protected by an outer polytetrafluoroethylene membrane under the periosteum and parietal muscles and an inner membrane between the dura mater and the parietal bone. (2) In the single membrane group (n = 20), only the outer membrane was placed. The right defect was not covered with any membrane and served as control. The animals were killed after 30 days. None of the control defects demonstrated complete or partial bone regeneration. In the single membrane group, the experimental site did not regenerate in 15 animals, partially in four, and completely in one. In the double membrane group, six of the experimental defects had complete closure with bone, two had partial closure, and one no closure.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
PURPOSE This retrospective review examines response, local control and freedom from distant failure for patients with locally advanced breast cancer treated by chemotherapy and radiotherapy without routine surgery. METHODS AND MATERIALS 67 patients were treated between January 1980 and December 1988 at Westmead Hospital, NSW, Australia. Median follow-up for surviving patients was 56 months. Four successive protocols evolved, each with three phases induction chemotherapy (adriamycin or novantrone, cyclophosphamide) (three cycles), radiotherapy then chemotherapy (cyclophosphamide, methotrexate, 5-fluorouracil) of progressively shorter duration. Radiotherapy and chemotherapy were concurrent in the fourth regimen. RESULTS Clinical complete response (disappearance of all known disease) after chemotherapy, radiotherapy and additional chemotherapy was 18%, 55% and 79% respectively. Seven additional patients subsequently underwent mastectomy (N = 2), local excision (N = 1) or a radiation boost (N = 4) for a total complete response rate of 90%. Twenty one patients (31%) failed to achieve a complete response (N = 7) or recurred locally (N = 14). The crude 2-year rate of local recurrence was 50% for tumors > 10 cm (N = 10) and 14% for smaller tumors (n = 57) and was not influenced by protocol. Two-year actuarial freedom from distant failure was 67% at 2 years. CONCLUSION Local control can be achieved for patients with locally advanced breast cancer with a primary tumor < 10 cm using chemotherapy and radiotherapy without routine mastectomy.
