An analysis of 11,196 burn admissions and evaluation of conservative management techniques.

We present an 8-year analysis (1993-2000) of 11,196 burn admissions with an average of 116.6 patients per month. Patients were largely treated by conservative techniques. The mean burn percentage was 50.35. Almost 80% of admissions were in the 16-55 years age group. Paediatric and geriatric burns were 17.1 and 3.1%, respectively. Flame burns accounted for 82.15% of admissions and of these 77.5% were sustained in the kitchen. A total of 35.32% of flame accidents were due to malfunctioning kerosene pressure stove. The overall mortality was 51.80%. These figures need further qualification because 46.8% of patients had more than 50% BSA burns and 50.72% patients reported to the hospital more than 6h after sustaining burns. Patients with <60% BSA burns, and who were received within 6h of injury had a mortality of 23% only. Significantly, 1078/1952 deaths (55.23%) of patients <60% BSA burns took place in first 6 days of admission when 3639 patients with <60% BSA injury were received more than 6h after burn injury. This reflects that even if economic constraints preclude one from having the best infrastructure reasonable mortality rates are still achievable with conservative line of management, even in face of a heavy work load. This also makes one question the cost effectiveness of high cost technology in burn management.

Radical correction of secondary nasal deformity in unilateral cleft lip patients presenting late.

It is universally acknowledged that correction of a cleft lip nasal deformity continues to be a difficult problem. In developing countries, it is common for patients with cleft lip deformities to present in their early or late teens for correction of severe secondary lip and nasal deformities retained after the initial repairs were carried out in infancy or early childhood. Such patients have never had the benefit of primary nasal correction, orthodontic management, or alveolar bone grafting at an appropriate age. Along with a severe nasal deformity, they present with alveolar arch malalignments and anterior fistulae. In the study presented here, a strategy involving a complete single-stage correction of the nasal and secondary lip deformity was used. In this study, 26 patients (nine male and 17 female) ranging in age from 13 to 24 years presented for the first time between June of 1996 and December of 1999 with unilateral cleft lip nasal deformity. Eight patients had an anterior fistula (diameter, 2 to 4 mm) and 12 patients had a secondary lip deformity. An external rhinoplasty approach was used for all patients. The corrective procedures carried out in a single stage in these patients included lip revision; columellar lengthening; repair of anterior fistula; augmentation along the pyriform margin, nasal floor, and alveolus by bone grafts; submucous resection of the nasal septum; repositioning of lower lateral cartilages; fixation of the alar cartilage complex to the septum and the upper lateral cartilages; augmentation of nasal dorsum by bone graft; and alar base wedge resections. Medial and lateral nasal osteotomies were performed only if absolutely indicated. The median follow-up period was 11 months, although it ranged from 5 to 25 months. Overall results have been extremely pleasing, satisfactory, and stable. In this age group (13 years of age or older), it is not fruitful to use a technique for nasal correction that corrects only one facet of the deformity, because no result of nasal correction can be satisfactory until septal deviations and maxillary deficiencies are addressed along with any alar repositioning. The results of complete remodeling of the nasal pyramid are also stable in these patients because the patients' growth was nearly complete, and all the deformities could be corrected at the same time, leaving no active deforming vector. These results would indicate that aesthetically good results are achievable even if no primary nasal correction or orthodontic management had been previously attempted.

Salmonella senftenberg: a new pathogen in the burns ward.

This is the first report of Salmonella senftenberg serovar outbreak in a burns unit. This unit admits about 2000 patients with major burn injuries annually. Routine sampling from wound swabs in December 1995 revealed S. senftenberg in a few samples following which a study was instituted from January to March 1996. Of 446 burn admissions during this period 80 patients were culture positive for S. senftenberg in wound swabs. The protocol for investigation included wound swabs on admission and then at biweekly interval, blood culture studies on clinically toxic patients, anti-microbial sensitivity studies, environmental sampling and hand swabs and stool cultures from about 50 staff members of the burns ward. No wound swab at the time of admission was positive for S. senftenberg. Environmental study and the study of staff members did not reveal any obvious source of the infection. S. senftenberg strains were sensitive to more than seven of the 11 anti-microbials tested at the beginning of the study but later 96.3% of the strains showed multidrug (more than three drugs) resistance. By April 1996 the isolates became negligible and later disappeared completely. The organism resurfaced again in March 1997 and the same study was instituted again on 413 admissions between March and May 1997. Fifty patients were culture positive for S. senftenberg. This time stool sample from one burn dresser tested positive for S. senftenberg. Interestingly, again at the beginning of the second outbreak the Salmonella strains were sensitive to 9 out of 11 anti-microbials tested, but later 96.11% strains became multidrug resistant. S. senftenberg strains showed maximum resistance to amoxycillin (97.5%) and minimum to chloramphenicol, tetracycline and cotrimoxazole (12%). It was noticed that Salmonella strains surfaced in wound swabs after 3-4 weeks of hospital stay. Forty-five out of 130 patients studied, in both the episodes, died due to septicemia. The majority of the patients who died had sustained > 60% TBSA burns. Blood cultures were done in 34/130 patients and eight yielded growth (2 S. senftenberg, 4 Klebsiella spp., and two Pseudomonas spp.)

Comparative study of technetium-99m bone scans and orthopantomography in determining mandible invasion in intraoral squamous cell carcinoma.

The accuracy of preoperative assessment in determining invasion of the mandible by intraoral squamous cell carcinoma was analyzed in 48 patients who underwent mandibulectomy, and the results correlated with the histopathological reports of the resected specimens. Only 50% of the patients underwent the "ideal" surgery based primarily on clinical judgement, whereas 10 patients in the series were significantly undertreated. Clinical judgement and routine preoperative x-rays are accurate in cases where there is gross involvement of the mandible (17 of 19) but are significantly less successful in determining early bone invasion, invasion of the periosteum, or periosteal new bone formation. In such cases (26 of 48), a technetium-99m bone scan provides additional information. A grading system for reporting orthopantomographics (OPTs) and bone scans has been developed and utilized to form a reference grid to determine the optimum extent of mandibular surgery. The results show that using this protocol, unnecessary mandibular surgery may be reduced and inadequate surgical excision avoided.

Mechanics of movement for rotation flaps and a local flap template.

After studying the mechanics of rotational movement, it has become apparent that there exists a local flap template for triangulated defects. Predominant rotation and transposition movements lie at extreme ends of its spectrum. This concept offers a design improvement by which these flaps can be executed with ease and confidence in all areas of the body. Several design variations are available from the template, making the hypothesis versatile and flexible. Underlying this success is the strategic placement of the triangulated defect within an imaginary circle of skin tissue around it. The concept also provides a logical and comprehensive teaching model.

Faciomaxillary fractures in north India. A statistical analysis and review of management.

An analysis of the incidence of facial fractures and their combinations is presented along with an evaluation of our techniques of fracture reduction and fixation. Two hundred and sixty two patients with facial fractures treated between January 1982 and December 1983 at the Postgraduate Institute of Medical Education and Research, Chandigarh, form the basis of this study. Simple methods have been used for reduction and fixation for the last 20 years without any major modification, as they have provided satisfactory results. Road traffic accidents are the leading aetiological factor in both sexes. More than 75% of the cases were in the 16-45 year age group. The mandible was the most frequently fractured bone. Contrary to previous reports we found that the parasymphseal region was more commonly fractured than the subcondylar region. More than 50% of the maxillary and zygomatic fractures were a part of the panfacial group. Orbital and nasoethmoidal fractures were relatively uncommon.

Geometric considerations in the design of rotation flaps in the scalp and forehead region.

The classical transposition and rotation flaps are well known. Cosmetic considerations in the scalp and forehead region limit the use of a flap design that requires a skin graft for a donor defect. On sound geometric principles, the classical flap designs are suitably modified here to have a somewhat equal proportion of transposition and rotation. This "modified rotation flap" design works to a maximum advantage in the inextensible region of the scalp and forehead by providing single-stage primary closure of moderate to large defects. No backcuts are ever necessary with this flap design. Use of this principle to modify the rotation flap design for closure of an extended midline forehead defect following rhinoplasty allows a still wider (up to 6.5 cm) midline forehead flap to be available for rhinoplasty with primary closure of the donor defect.
