ABSTRACT

BACKGROUND: Given numerous publications and clinical trials regarding axillary management in breast cancer, we sought to summarize this complex literature to help clarify this field for clinicians. This systematic review focuses on the role of irradiation of the axillary nodes (locoregional nodal irradiation [LRNI]) in the management of the axilla in patients with early-stage breast cancer in various clinical settings. METHODS: We searched MEDLINE and EMBASE databases, the Cochrane library, the proceedings of the ASCO, the ASTRO, the ESMO, the ESTRO, and the San Antonio Breast Cancer Symposium (2016-2019) meetings. The quality of the studies was assessed with design-specific tools. The study was registered in PROSPERO. RESULTS: We included one systematic review, one individual patient data (IPD) meta-analysis, and five randomized controlled trials (RCTs). After axillary lymph node dissection (ALND), LRNI resulted in small benefits in breast cancer specific mortality, locoregional recurrence, and distant metastases-free survival but not overall survival. After a positive sentinel node biopsy (SLNB), LRNI may provide equivalent locoregional control and disease-free survival (DFS) compared to ALND with a lower risk of lymphedema. No randomized data is available for the neoadjuvant setting. CONCLUSIONS: The summary of the role of radiation, is relevant to radiation oncologists for choosing the correct cohort of patient requiring LRNI and to surgeons making clinical decisions regarding the timing and type of breast reconstruction offered to patients.

ABSTRACT

Background and Purpose: Adjuvant whole-breast irradiation after breast-conserving surgery, typically delivered over several weeks, is the traditional standard of care for low-risk breast cancer. More recently, hypofractionated, partial-breast irradiation has increasingly become established. Neoadjuvant single-fraction radiotherapy (rt) is an uncommon approach wherein the unresected lesion is irradiated preoperatively in a single fraction. We developed the signal (Stereotactic Image-Guided Neoadjuvant Ablative Radiation Then Lumpectomy) trial, a prospective single-arm trial to test our hypothesis that, for low-risk carcinoma of the breast, the preoperative single-fraction approach would be feasible and safe. Methods: Patients presenting with early-stage (T < 3 cm), estrogen-positive, clinically node-negative invasive carcinoma of the breast with tumours at least 2 cm away from skin and chest wall were enrolled. All patients received prone breast magnetic resonance imaging (mri) and prone computed tomography simulation. Treatable patients received a single 21 Gy fraction of external-beam rt (as volumetric-modulated arc therapy) to the primary lesion in the breast, followed by definitive surgery 1 week later. The primary endpoints at 3 weeks, 6 months, and 1 year were toxicity and cosmesis (that is, safety) and feasibility (defined as the proportion of mri-appropriate patients receiving rt). Results: Of 52 patients accrued, 27 were successfully treated. The initial dosimetric constraints resulted in a feasibility failure, because only 57% of eligible patients were successfully treated. Revised dosimetric constraints were developed, after which 100% of patients meeting mri criteria were treated according to protocol. At 3 weeks, 6 months, and 1 year after the operation, toxicity, patient- and physician-rated cosmesis, and quality of life were not significantly different from baseline. Conclusions: The signal trial presents a feasible method of implementing single-dose preoperative rt in early-stage breast cancer. This pilot study did not identify any significant toxicity and demonstrated excellent cosmetic and quality-of-life outcomes. Future randomized multi-arm studies are required to corroborate these findings.

ABSTRACT

STUDY DESIGN: A retrospective registry review. OBJECTIVES: To determine the incidence of cervical spine (CS) injuries and collar complications in severely injured paediatric trauma patients. SETTING: Regional Trauma Centre, Children's Hospital. METHODS: A retrospective review of 365 paediatric severe trauma patients (0-17 years), defined as an Injury Severity Score (ISS)≥12, admitted to the paediatric intensive care unit (PICU). RESULTS: Clinically significant CS injuries occurred in 5% (n=18/365) of trauma patients, in 9% (n=13/149) of traumatic brain injury (TBI) patients and in 11% (n=6/56) of in-hospital trauma deaths. CS injuries were suspected before imaging in 33% (n=6/18) of patients based on either motor/sensory impairment or shock. CS injuries were deemed unstable in 61% (n=11/18) of patients. Patients with CS injuries had higher ISS, and longer PICU and hospital stays (P<0.05). CS collar complications occurred in 10% of patients, mainly identified by day 6 and consisting of either erythema or ulcers. Patients with CS collar complications were older and more likely to have TBI, lower Glasgow Coma Scale (GCS) scores, longer PICU and hospital stays, and increased days to CS clearance (P<0.05). Three CS X-rays, together with flexion/extension views, were used most frequently for CS clearance. CONCLUSION: CS injuries were prevalent in severely injured paediatric trauma patients, particularly in those with TBI and in nonsurvivors. CS collar complications were associated with a lower GCS and longer CS clearance times. Attention to CS collar management protocols and earlier CS clearance with computed tomography/magnetic resonance imaging in obtunded patients might reduce CS collar complications.

ABSTRACT

Stereotactic breast biopsy (SBB) is the gold standard for minimally invasive breast cancer diagnosis. Current systems rely on one of two methods for needle insertion: A vertical approach (perpendicular to the breast compression plate) or a lateral approach (parallel to the compression plate), While the vertical approach is more frequently used, it is not feasible in patients with thin breasts (<3 cm thick after compression) or with superficial lesions. Further, existing SBB guidance hardware provides at most one degree of rotational freedom in the needle trajectory, and as such requires a separate skin incision for each biopsy target. The authors present a new design of lateral guidance device for SBB, which addresses the limitations of the vertical approach and provides improvements over the existing lateral guidance hardware. Specifically, the new device provides (1) an adjustable rigid needle support to minimize needle deflection within the breast and (2) an additional degree of rotational freedom in the needle trajectory, allowing the radiologist to sample multiple targets through a single skin incision. This device was compared to a commercial lateral guidance device in a series of phantom experiments. Needle placement error using each device was measured in agar phantoms for needle insertions at lateral depths of 2 and 5 cm. The biopsy success rate for each device was then estimated by performing biopsy procedures in commercial SBB phantoms. SBB performed with the new lateral guidance device provided reduced needle placement error relative to the commercial lateral guidance device (0.89 +/- 0.22 vs 1.75 +/- 0.35 mm for targets at 2 cm depth; 1.94 +/- 0.20 vs 3.21 +/- 0.31 mm for targets at 5 cm depth). The new lateral guidance device also provided improved biopsy accuracy in SBB procedures compared to the commercial lateral guidance device (100% vs 58% success rate). Finally, experiments were performed to demonstrate that the new device can accurately sample lesions within thin breast phantoms and multiple lesions through a single incision point. This device can be incorporated directly into the clinical SBB procedural workflow, with no additional electrical hardware, software, postprocessing, or image analysis.

ABSTRACT

We report the successful management of a five-year-old child with severe diabetic ketoacidosis with dehydration, who received his initial resuscitative fluids and a continuous infusion of insulin via an intraosseous needle. The patient had presented to a remote community hospital and intravenous access could not be gained. The correction of hyperglycaemia and metabolic acidaemia was achieved at a rate comparable to intravenous therapy. No complications were observed. Although intraosseous access is well described in paediatric resuscitation guidelines, it is not mentioned in International Diabetes Society guidelines for the management of diabetic ketoacidosis. Alternatives to intravenous administration of insulin delivery recommended in such guidelines, such as the subcutaneous or intramuscular routes, may be less appropriate than the intraosseous route. This route can also allow resuscitation fluids and other drugs to be reliably administered in children with diabetic ketoacidosis and severe dehydration where intravenous access can not be attained. We suggest that the potential role of intraosseous access, when intravenous access can not be obtained, should be considered when management guidelines for paediatric diabetic ketoacidosis with dehydration are reviewed.

ABSTRACT

Stereotactic breast biopsy (SBB) is the gold standard for noninvasive breast cancer diagnosis. Current systems rely on one of two methods for needle insertion: a top-approach (from above the breast compression plate) or a lateral-approach (parallel to the compression plate). While the top-approach is more commonly used, it is not feasible in patients with thin breasts (less than 2.5 cm thickness after compression), or with superficial lesions. We present a novel design of lateral guidance support for SBB, which addresses these limitations of the top-approach, and provides improvements over existing lateral support hardware. This device incorporates spherical linkages to allow two degrees of rotational freedom in the needle trajectory for increased targeting flexibility, as well as an adjustable rigid needle support to minimize needle deflection within the tissue. Needle placement error in SBB experiments is compared using both the new lateral guidance device and a commercial lateral guidance device in agar phantoms. The effect of elevation angle on needle placement accuracy using the new lateral guidance device is also assessed. Finally, a biopsy accuracy experiment is presented using a certified SBB phantom to compare the new design and the commercial lateral guidance device. In these experiments, SBB performed using the new lateral guidance device results in improved needle placement error and biopsy accuracy, while increasing targeting flexibility and maintaining procedural workflow.

ABSTRACT

Fusobacterium necrophorum infections are rare. We report a 15-year-old male who presented with tachycardia, nausea, vomiting, diarrhoea and ankle pain. He rapidly deteriorated requiring ventilation and vasopressors. Imaging of his thorax showed airspace consolidation, pulmonary cavitations and empyema. The ankle required drainage of purulent material. A thrombus in his internal jugular vein (Lemierre's syndrome) and an abscess in his obturator internus were subsequently found. Fusobacterium necrophorum was identified in blood culture on day nine. The patient recovered with antibiotics and surgical interventions for empyema and septic arthritis. Fusobacterium necrophorum should be a suspected pathogen in septic shock complicated by metastatic abscess formation.

ABSTRACT

Described is a 2-year-old child who required a tracheotomy for an obstructing laryngeal tumor. Post-operatively the child responded with extreme anxiety and refused to cooperate with tracheostomy care including suctioning, tie changing and cannula change. A novel approach was attempted. We performed a tracheotomy on the child's favorite doll and taught her to perform all the necessary tracheostomy care on the doll. Once the child became accustomed to treating the doll, it became much easier to care for her tracheostomy and compliance to treatment improved greatly to the point were restraint was no longer required. This model of mock surgery and care of a child's doll may be helpful in treating young children with tracheotomies.

ABSTRACT

The value of unenhanced spiral CT (UESCT) for investigating acute flank pain suggestive of urinary tract calculi is increasingly appreciated in the last few years. Recent studies have identified the advantages of UESCT in recognizing alternative findings within or outside the urinary tract. We sought to determine how narrowing the referral base for the UESCT would affect the discovery of potentially significant alternative findings in patients with acute flank pain suggestive of renal colic. Between January 1999 and December 1999, 425 patients, 271 (63.8%) men and 154 (36.2%) women who were 1-90 years old (mean 45.7 years old) with acute flank pain were studied with UESCT. CT studies were solely ordered by urologists, and only patients with intractable renal colic or patients that returned more than once to the emergency room with the complaint of acute flank pain were studied. A calculus within the ureter was diagnostic of an obstructive stone. Any other abnormality within the abdomen and pelvis was reported. A ureteral calculus was detected on 251 (59%) CT scans. Nineteen (4.5%) CT scans were consistent with recent excretion of a stone. In 112 (26.3%) CT scans, the cause for the patient's acute flank pain could not be explained. Forty-three (10.1%) alternative significant diagnoses that explain the patient's complaints were found. Nineteen (44%) were findings related to the urinary tract, and 24 (56%) were not related to the urinary tract. Ninety-seven (22.3%) additional findings not significant to the patient's current complaint were also reported. Even when narrowing the indications for the UESCT, about 10% of significant alternative findings to urinary stones were encountered. The variety of diagnoses found unexpectedly on the UESCT that alter a patient's management demonstrates the pivotal role of UESCT in triaging these patients rapidly towards optimal therapy. The UESCT can be used as a useful screening tool, sometimes revealing the exact pathology and sometimes directing the radiologist to the modality by which to continue.

ABSTRACT

OBJECTIVE: To evaluate benefits and risks of open lung biopsy in children with respiratory failure. DESIGN: Retrospective chart review. SETTING: A 36-bed pediatric critical care unit in a tertiary care, university-based hospital. PATIENTS: We studied 31 patients with respiratory failure who underwent 33 open lung biopsies. MEASUREMENTS AND MAIN RESULTS: The charts of all children in the critical care unit with respiratory failure who underwent an open lung biopsy over a 10-yr period (1989-98) were reviewed. Of 33 open lung biopsies performed, 76% (25 of 33) led to a relevant change in medical management. Complications were seen in 45% of patients, predominantly attributable to airleak (33%) without affecting respiratory function. An infectious agent was detected by open lung biopsy in ten patients; bronchoalveolar lavage performed before open lung biopsy failed to isolate the infection in eight of ten patients. CONCLUSIONS: In children with undiagnosed or persisting respiratory failure, open lung biopsy is a useful diagnostic procedure that leads to significant changes in medical management and increases the diagnostic yield for infections. Despite the relatively high complication rate, open lung biopsy should be performed routinely in this group of patients.

ABSTRACT

STUDY OBJECTIVE: To compare the effect of the prone position (PP) vs supine position (SP) on oxygenation in children with acute respiratory failure (ARF). DESIGN: Prospective, randomized controlled trial. SETTING: A 36-bed pediatric critical-care unit in a tertiary-care, university-based children's hospital. PATIENTS: Ten children (mean [SD] age, 5 +/- 3.6 years) with ARF with a baseline oxygenation index (OI) of 22 +/- 8.5. INTERVENTIONS: Following a period of stabilization in the SP, baseline data were collected and patients were randomized to one of two groups in a two-crossover study design: group 1, supine/prone sequence; group 2, prone/supine sequence. Each position was maintained for 12 h. Lung mechanics and acute response to inhaled nitric oxide were examined in each position. MEASUREMENTS AND MAIN RESULTS: OI was significantly better in the PP compared to the SP over the 12-h period (analysis of variance, p = 0.0016). When patients were prone, a significant improvement in OI was detected (7.9 +/- 5.3; p = 0.002); this improvement occurred early (within 2 h in 9 of 10 patients) and was sustained over the 12-h study period. Static respiratory system compliance and resistance were not significantly affected by the position change. Inhaled nitric oxide had no effect on oxygenation in either position. Urine output increased while prone, resulting in a significantly improved fluid balance (+ 6.6 +/- 15.2 mL/kg/12 h in PP vs + 18.9 +/- 13.6 mL/kg/12 h in SP; p = 0.041). No serious adverse effects were detected in the PP. CONCLUSION: In children with ARF, oxygenation is significantly superior in the PP than in the SP. This improvement occurs early, remains sustained for a 12-h period, and is independent of changes in lung mechanics.

ABSTRACT

OBJECTIVE: To review the imaging appearances, management and outcome of a large number of children with intussusception owing to pathologic lead points (PLP) in an attempt to define the role of various imaging modalities in this clinical setting. MATERIALS AND METHODS: Review of the records and imaging studies of 43 children with intussusception due to PLP diagnosed between 1986 and 1999. RESULTS: The commonest PLP found were Meckel diverticulum, polyps, Henoch-Schonlein purpura and cystic fibrosis. PLP were depicted on sonography in 23 (66%) of 35 patients, on computed tomography in 5 (71%) of 7, on air enema in 3 (11%) of 28, and on barium enema in 6 (40%) of 15. Air enema successfully reduced 60% of the intussusceptions. Nine children had recurrent intussusceptions. CONCLUSION: Sonography depicted two-thirds of PLP and provided a specific diagnosis in nearly one-third of our series. Our review does not provide sufficient data on how to continue the investigation of those patients in whom sonography does not depict a PLP but in whom there is a high index of suspicion for its presence. It remains a diagnostic challenge as to how to search for PLP in these patients, and other imaging modalities have to be requested according to each particular case.

ABSTRACT

BACKGROUND: To analyze the spectrum of clinical features, management and outcome of children with documented spontaneous reduction of intussusception (SROI). MATERIALS AND METHODS: Review of records of 50 children (33 boys, 17 girls; age range 11 days-15 years; mean age 4 years) with documented SROI, in whom intussusception was initially diagnosed by sonography (US) in 44, air enema in 2, and computed tomography in 4, in the 6-year period 1992-1998. RESULTS: Symptoms suggestive of intussusception were present in 21 (3 of whom had Henoch-Schönlein purpura and 4 had previous ileocolic intussusception reduced by air enema). Intussusception was an incidental finding in the other 29, in 28 of whom the finding was in the small bowel. Intussusception was limited to the small bowel in 43 and was ileocolic in 7. SROI was usually documented on US. Laparotomy performed in only 4 showed no evidence of intussusception or pathologic lead point. Outcome in all patients was favorable. CONCLUSIONS: SROI may present in symptomatic or asymptomatic children and occurs more commonly than previously reported. These intussusceptions are usually short-segment, small-bowel intussusceptions with no recognizable lead point. In asymptomatic patients, conservative observation is warranted. Intervention should be dictated by the clinical findings in symptomatic patients.

ABSTRACT

OBJECTIVE: To asses the yield and contribution of a routine predetermined repeat head computed tomographic (CT) scan within 24-36 hrs in pediatric patients with moderate to severe head trauma. DESIGN: Records review. SETTING: Five pediatric intensive care units. PATIENTS: We reviewed the charts of 173 consecutive pediatric patients with moderate to severe head trauma (Glasgow Coma Scale score of < or = 11) that survived the first 24 hrs after being admitted to five Israeli trauma centers. Clinical data collected included status at admission, at the time between the first and second CT scans, and after the second scan. Head details of the first, second, and, if performed, third CT scan were collected. Treatment strategy during each period was recorded, including any change in treatment after each CT scan. MEASUREMENTS AND MAIN RESULTS: A total of 47 (27%) of the second CT scans showed new lesions including six intracranial hemorrhages, 17 cases of worsening brain edema, and 18 newly diagnosed brain contusions. However, none of these findings necessitated surgical intervention or any change in therapy. Of the 67 patients who underwent a third CT scan, two cases required surgical intervention because of new findings in the third CT. CONCLUSIONS: A second routine prescheduled head CT scan within 24-36 hrs after admission in pediatric patients with moderate to severe head trauma is unlikely to yield any change in therapy. Clinically and intracranial pressure-oriented CT scan may better select and diagnose patients who require changes in therapy, including surgery. Studies aimed to determine the ideal timing for the second are warranted.

ABSTRACT

The authors report a case of a 14-year-old boy with familial dysautonomia (FD) in whom a small-bowel infarction developed during a dysautonomic crisis. Atypical features of the presentation included hypotension with prolonged fever and abdominal distension. The authors postulate that the bowel infarction was caused by prolonged hypoperfusion. It is recognized that the small bowel in normal subjects can adapt to periods of ischemia without irreversible injury. The authors speculate that the known abnormal systemic cardiovascular regulation in patients with FD may adversely affect splanchnic blood flow, which led to the catastrophic consequences in this case. This report draws attention to the risk of significant ischemic complications during a dysautonomic crisis, especially in the face of atypical features, and emphasizes the challenging cardiovascular management of such patients.

ABSTRACT

BACKGROUND: Patients with ataxia telangiectasia (AT), known to have an inherent increased susceptibility to the development of cancer, may present with malignancies that are unusual for the patient's age, are often difficult to diagnose clinically and radiographically and respond poorly to conventional therapy. MATERIALS AND METHODS: We reviewed the clinical presentation and imaging studies of 12 AT patients who developed malignancies. RESULTS: Eight of the twelve patients developed non-Hodgkin's lymphoma (CNS, thorax, bone), two developed Hodgkin's disease, and two were diagnosed with gastrointestinal mucinous adenocarcinoma. CONCLUSION: The lymphomas were commonly extra nodal, and infiltrative rather than mass-like. The recognition of the tumors was often delayed due to confusion with the known infectious complications in AT patients.

ABSTRACT

BACKGROUND: The clinical literature on the incidence and subsequent mortality of asthma has come primarily from the experiences of large tertiary referral centers, particularly in Western Europe and North America. Consequently, very little has been published on the incidence, management, and outcome of asthma in smaller, community-based intensive care units. OBJECTIVES: The purpose of this study was to explore the course and outcome of children with acute severe asthma treated within a community hospital PICU compared with those described in the literature from larger tertiary referral centers. DESIGN: A retrospective analysis of 49 asthmatic children admitted to the Pediatric Intensive Care Unit (PICU) over a 10-year period was performed. MEASUREMENTS AND RESULTS: The mean age was 5.2 years (range 2 months to 16 years), and the male:female ratio was 3:1. Duration of symptoms prior to admission to hospital was less than 24 hours in 60.4% of the patients. The majority of patients was not treated with either inhaled or oral steroids before admission. Drugs used in the PICU included nebulized beta2-agonists, theophylline, steroids, intravenous salbutamol, and intravenous isoproterenol. Although a pharmacologic approach was successful in the majority of patients, intubation and mechanical ventilation were necessary for progressive hypercapnea, exhaustion, and cardiorespiratory arrest in 11/49 of these patients. The average stay in the ICU for our patient group was 2.4 days. Intubated patients had a mean average stay of 3.5 days. Two patients had pneumothorax related to positive pressure ventilation, requiring chest tube insertion for drainage. There were no deaths among the 49 patients admitted to our PICU. CONCLUSIONS: These data show that for acute severe asthma, outcome is comparable in a community PICU to a tertiary referral institution. We conclude that early ICU admission along with close monitoring is important in reducing morbidity and mortality in children with severe asthma.

ABSTRACT

The rate of sudden infant death syndrome (SIDS) In Israel is relatively low (0.5-0.9:1,000). Home cardiorespiratory monitoring (HM) is an accepted practice in infants at high risk for SIDS. We report our experience with 261 infants who were referred to our SIDS prevention program. They included: 52 preterm infants with apneas and bradycardias, 83 SIDS siblings (3 twins), 22 infants of drug-addicted mothers, and 104 infants after an idiopathic apparent life-threatening event (ALTE). HM was performed in 40 of 52 preterms, 38 of 83 SIDS siblings, all 22 infants of addicted mothers and 67 of 104 post-ALTE. All received 24 h/day medical and technical backup as well as emotional support, and were closely followed until 15 months of age. None of the 261 infants died. Five infants experienced six ALTEs that required resuscitative measures; another 28 infants had monitor alarms judged as real by the caregivers. The average duration of HM was 3.2 months (range 1-7). In 8 of 167 cases the parents stopped HM earlier than recommended, and in 34 of 167 cases (20%), parents continued HM beyond the time when discontinuation was recommended by the medical personnel. Among the caregivers, 85% found HM to be reassuring and stated that it helped them to conduct a normal life. We suggest that in our population, HM may have a favorable effect on family life. With close backup and support, most families will benefit from HM and will gain reassurance that will enable them to conduct normal life.
