STUDY DESIGN: Retrospective study. PURPOSE: To highlight risk factors, recurrence patterns and multimodal treatment in management of recurrent giant cell tumors (GCTs). OVERVIEW OF LITERATURE: GCTs of the spine are rare and challenging entities. Recurrences are very common and warrant complex management to prevent multiple recurrences. Gross total resection is preferred over subtotal procedures to prevent recurrences. However, resection is associated with morbidity and mortality. Proper understanding of risk factors and a high index of suspicion helps to spot recurrences early and aids in subsequent management. METHODS: Ten patients (six females, four males) with recurrent GCTs underwent 17 interventions. There were six lesions in the thoracic spine, two in the cervical spine and two in the lumbar spine. Recurrences were managed with preoperative digital subtraction embolization, intralesional curettage and postoperative radiotherapy. RESULTS: The average age at intervention was 31.3 years. The average duration of recurrence in patients following index surgery in a tertiary care hospital and surgery elsewhere was 7.3 years and was 40 months, respectively. The minimum recurrence-free interval after the last recurrent surgery was 10 years. CONCLUSIONS: Our study reports the largest recurrence-free interval for GCTs. Recurrent GCTs are challenging entities. Understanding of risk factors and meticulous planning is required to prevent recurrences. Intralesional surgery could be a safer and effective modality in managing recurrences.

2.A review of 42 asthmatic children with allergic bronchopulmonary aspergillosis
Asia Pacific Allergy 2017;7(3):148-155
BACKGROUND: Allergic bronchopulmonary aspergillosis (ABPA) in children with asthma, not associated with cystic fibrosis, is yet to receive the recognition it deserves. OBJECTIVE: To highlight the presentation of ABPA in children with asthma. METHODS: This retrospective review documents the occurrence of pediatric ABPA over a period of 31 years in one unit. Children with asthma, eosinophilia and infiltrates on chest radiograph were screened for ABPA. In these patients, demonstration of immediate hypersensitivity response against Aspergillus species along with serological profile and pulmonary function testing were done. Bronchography/computed tomography (CT) of the chest demonstrated central bronchiectasis (CB). CT of the paranasal sinuses was done in patients with upper airways symptoms. In those suspected with allergic Aspergillus sinusitis (AAS) consent was sought from the parents for the invasive procedure needed for the diagnosis of AAS. RESULTS: Of the 349 patients with ABPA diagnosed, 42 (12.03%) were in the pediatric age group. The mean age on presentation was 12.9 ± 4 years with a male preponderance. All patients had asthma and positive intradermal/skin prick test against Aspergillus species. Ring shadows, the most common radiological presentation, were seen in 28 of 42 patients. Bronchography/CT of the chest demonstrated CB, a feature pathognomic of ABPA, in 32 of 42 patients. High attenuation mucus plugs was observed in 7 of 36 patients while ABPA-seropositive was diagnosed in 10 of 42 patients. On imaging, sinusitis was seen in 20 of 30 patients with upper airways symptoms of whom eight had suspected AAS. Three parents consented for surgery, which confirmed the diagnosis. CONCLUSION: This study highlights the need to evaluate asthmatic children for ABPA as also to exclude AAS.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is now recognized as a systemic disorder with many comorbidities. Atopy in patients with COPD and upper airways symptoms has not been characterized. OBJECTIVE: We investigated the occurrence and impact of aeroallergen sensitisation in patients with COPD and upper airways symptoms.

Methods:
Five consecutive patients undergoing revision deformity correction with sublaminar wires in situ were included in this study. Patients were divided in two groups based on the technique of PA insertion. A total of 91 PAs were inserted using either a freehand technique (group A) or 3D printed templates (group B) (34 vs. 57). The placement of PAs was classified according to a postoperative computed tomography scan using Neo’s classification. Perforation beyond class 2 (>2 mm) was termed as a misplaced screw. The average time required for the insertion of screws was also noted.
Results:
Mean age, surgical time, and blood loss were recorded. The change in mean Cobb’s angle in both groups was also recorded. The difference in rates of misplaced screws was noted in group A and group B (36.21% vs. 2.56%); however, the mean number of misplaced PAs per patient in group A and group B was statistically insignificant (6.5±3.54 vs. 4.67±1.53, p =0.4641). The mean time required to insert a single PA was also statistically insignificant (120±28.28 vs. 90±30 seconds, p =0.3456).
Conclusions
Although 3D printed PSTs help to avoid the misplacement of PAs in revision deformity correction surgeries with sublaminar wires in situ, the mean number of misplaced screws per patient using this technique was found to be statistically insignificant when compared with the freehand technique in this study.
