Maxillofacial trauma among Indians.

Orofacial injuries constitute the medico-legal cases reported, especially, in cases associated with road traffic accidents, assaults, and violence making it an emerging healthcare problem. Therefore, it is of interest to document data on the maxillofacial trauma and fractures among Indians. 150 subjects within the age of 15 to 60 years with maxillofacial fractures, detailed medical history including demographics, radiographs, medical history, associated injuries, and etiology of fractures were used for this study. Sites for both maxillary and mandibular fractures were noted. The type of intubation (medical insertion procedure) used and post-operative complications were also recorded. Lefort I, II, and III fractures were seen in 4%, 12%, 6% subjects respectively, whereas, ZMC fracture was seen in 66% study subjects. Mandibular fractures were most commonly seen in the para-symphysis region with 30% subjects followed by condylar region with 28.66% subjects. Data shows that maxillofacial trauma has a high incidence in India with RTA (road traffic accidents being the most common reason for the trauma seen in young males with significant concomitant injuries. Most common fracture is seen in mandible region. However, they can be managed well with very few postoperative complications.

Correlation Between BMI, Caries Prevalence, and Sugar-containing Beverage Intake in 6-10 Year Old Children.

Background: The beverages containing sugar are proven risk factors for obesity and dental caries. Therefore, owing to the shared risk factors, an interrelationship is suspected between BMI, sugar beverage consumption, and dental caries in children. Aims: The present trial was carried out to assess the interrelationship between BMI, sugar beverage consumption, and dental caries in children aged 6-10 years. Materials and Methods: Eighty-six children within the age range of 6-10 years answered the health questionnaire. The BMI was calculated, intra-oral assessment was done, the frequency of sweetened beverage consumption was recorded, and the collected data were subjected to the statistical evaluation to formulate results. Results: On evaluation, a non-significant difference was observed in BMI levels in the four groups (P = 0.12). Whole-milk intake also showed an inverse correlation with dental caries and BMI, but this correlation was statistically non-significant with the respective values of P = 0.57 and 0.55. A similar inverse relationship was seen for low-fat milk for caries and BMI with P = 0.65 and 0.45, respectively. Regarding soft drinks, 44.1% (n = 38) took soft drinks, and a non-significant relation between caries and intake as well as BMI and intake with P = 0.86 and 0.55, respectively. Conclusion: Within its limitations, the present study concludes that no correlation exists between BMI and dental caries as well as between sugar-containing beverage consumption and dental caries. Also, BMI and sugar-containing beverage consumption showed no correlation in children aged 6-10 years.

Complications and Functional Outcome of Femoral Head Fracture-Dislocation In Delayed and Neglected Cases.

INTRODUCTION: Delayed reduction of the hip in femoral head fracture dislocation increases the risk of osteonecrosis and adversely affects the functional outcome. MATERIALS AND METHODS: This retrospective study was designed to evaluate the outcome and complications of 138 patients with femoral head fracture dislocation treated by a single surgeon over a period of 22 years. Only seven patients presented within 24 h of injury and remaining all presented late. The hip joints could be reduced by closed manoeuvre in 105 patients, and 33 patients needed open reduction. The patients were managed conservatively or surgically. The mean follow-up period was 3.57 years (1-18 years). RESULTS: There were 119 males and 19 females. The mean age was 35.71 years (range, 18-70 years). Forty-two patients were managed conservatively, and 96 patients needed surgical treatment. The Kocher-Langenbeck approach was used in 40 patients, the trochanteric flip osteotomy in 14 patients, the Smith-Peterson approach in 31 patients, and the Watson-Jones approach in one patient. The femoral head fragment was fixed in 47.82% patients and excised in 11.59% patients. Primary total hip replacement (THR) was performed in 7.24% of patients through the posterior approach. 24.63% of patients developed complications with 14.49% of hip osteonecrosis, 2.89% posttraumatic osteoarthritis and 2.17% femoral head resorption. 55% of patients who developed osteonecrosis were operated through the posterior approach. Secondary procedures were needed in 14.48% of patients. The clinical outcome, as evaluated using the modified Harris Hip Score, was good to excellent in 52.89% of patients and poor to fair in 47.11% of patients. CONCLUSION: The incidences of osteonecrosis and secondary procedures are increased in delayed and neglected femoral head fracture dislocation. Osteonecrosis is commonly seen in Brumback 2A injuries and posterior-based approaches. All Brumback 3B fractures in such delayed cases should be treated with THR. Osteosynthesis or conservative treatment should be reserved for other types of injuries. A careful selection of treatment plan in such delayed cases can result in a comparable functional outcome as reported in the literature.

The Majority of Corona Mortis Are Small Calibre Venous Blood Vessels: A Cadaveric Study of North Indians.

PURPOSE: Corona mortis is an abnormal arterial or venous anastomosis between the external iliac and the obturator system of vessels and may cause significant hemorrhage during pelvi-acetabular fracture surgeries, hernia repair and laparoscopic gynecological procedures. Previous studies have estimated a prevalence of corona mortis between 34% and 70%. This cadaveric study was conducted to estimate the prevalence of corona mortis in the North Indian population. MATERIALS AND METHODS: Twelve cadavers (24 hemipelvises; 11 males and 1 female) with a mean age of 68 (range, 54-82) years were included in this study. RESULTS: Corona mortis was observed in 14 hemipelvises (58.3%). A total of 19 (79.2%) vascular anastomoses of diameter greater than 1 mm were observed; 5 hemipelvises (20.8%) had corona mortis on the right side, 9 hemipelvises (37.5%) on the left side and bilateral in 5 (41.7%) cases. Two hemipelvises (8.3%) had an arterial connection. An aberrant obturator artery was observed in 1 (4.2%) hemipelvis. A venous connection was found in 14 specimens (58.3% of hemipelvises). The average distance of the connecting vein from the symphysis pubis was 41 (35-70) mm. A vessel diameter of greater than 4 mm was observed in 4/24 (16.7%) of hemipelvises. CONCLUSION: The frequency of venous corona mortis was higher than arterial corona mortis and the majority (83.3%) were small calibre (<4 mm). The presentation pattern and the number of arterial or venous anastomoses were different in the majority of hemipelvises and dissimilar in both hemipelvises of the same cadaver in the majority of cases.

Effects of topical tranexamic acid during open reduction and internal fixation of acetabular fractures: A retrospective study.

OBJECTIVE: The aim of this study was to assess the effect of topical tranexamic acid on blood loss and transfusion rates in acetabular fracture surgery. METHODS: The medical records of 61 patients who underwent open reduction and internal fixation for acetabular fracture between 2012 and 2015 were retrospectively reviewed. The patients were divided into two groups: Group I consisted of 31 patients (19 men and 12 women, mean age: 52 ± 19 years) who received intraoperatively a topical tranexamic acid solution of 3 g and Group 2 consisted of 30 control patients (17 men and 13 women, mean age: 48 ± 24 years) who received only 0.9% saline solution. The groups were compared based on their intraoperative blood loss, Postoperative drain output at 24 and 48 h, and postoperative hemoglobin levels, and transfusion rates. RESULTS: The mean intraoperative blood loss was 410 ± 100 ml in Group 1, compared to 570 ml ± 160 ml of the control group (p < 0.05). The postoperative drain output after 24 h was 210 ± 70 ml in Group 1 compared to 330 ± 90 ml of the control group (p < 0.05). The drain output at 48 h was (50 ± 20 ml) in group 1 compared to 90 ± 40 ml of the control group (p < 0.05). The transfusion rate was significantly low group 1 (42%) than the control group (97%). Hemoglobin drop was again significantly less in tranexamic acid group (2.1 ± 1.1) than the control group (3.2 ± 1.3). The nadir postoperative hemoglobin was higher in the Group 1 (10.4 ± 1.5) than the control group (9.2 ± 1.3). CONCLUSION: Topical administration of tranexamic acid reduces intraoperative and postoperative blood loss in acetabular fracture surgery, decreasing transfusion rates. LEVEL OF EVIDENCE: Level III, Therapeutic Study.

Histopathological Evaluation of Dental Follicle Associated with Radiographically Normal Impacted Mandibular Third Molars.

INTRODUCTION: Removal of impacted mandibular third molar is a common procedure performed in oral surgery. Indications for removal of the third molar have generated much discussion in dentistry. The presence of pericoronal pathosis is generally accepted reason for the extraction of impacted mandibular third molars. Radiographic pathology is usually defined as a pericoronal radiolucency measuring about 2.5 mm or larger in any dimension. PURPOSE: This study aims to evaluate the histopathologic changes in radiographically normal dental follicles associated with impacted mandibular third molars. METHODS: After extraction of 50 impacted mandibular third molars, dental follicle associated with extracted teeth was placed in 10% formalin solution. Histopathologic examination was done. The type of pathological changes was recorded based on histopathological reports. Patients' gender, age, and radiographic parameters were recorded. RESULTS: Cystic changes were found in 24% of radiographically normal impacted mandibular third molars. Significant cystic changes were observed in position A vertically impacted lower third molars (ILTMs). Male predominance for cystic change was seen with a male-female ratio of 2:1. CONCLUSION: The result of the present study shows that radiographic analysis may not be reliable technique for the diagnosis of cystic changes in ILTM. The presence of cystic changes can be found even in radiographically normal impacted mandibular third molars. Hence, we recommend that impacted mandibular third molars should be removed and histopathological analysis should be conducted on all surgically extracted dental follicles.

Avascular Necrosis of Head of Femur in Dyskeratosis Congenita - A Rare Presentation.

Avascular necrosis of head of femur is a rare presentation in Dyskeratosis Congenita (DC). Aplastic anaemia, increased susceptibility to infections and fatal pulmonary complications often complicate the clinical scenario in these patients leading to short life span and difficulty in performing surgical interventions. The diagnosis initially and subsequent management by total hip replacement posed a great challenge. To our knowledge this is the first case report of any intervention in form of total hip Arthroplasty done in DC. At 5 years of follow up the patient is asymptomatic with no radiographic signs of loosening or lysis.

Alkaptonuric ochronosis.

Alkaptonuria, with its sequel, ochronosis, is a rare disease, with an incidence of 1:125,000 to 1:1 million worldwide. Reported cases of ochronotic arthropathy and other orthopedic manifestations are mostly limited to a single family tree, and few cases have been reported. This study highlights 9 previously unreported patients with sporadic presentation and varied orthopedic manifestations of alkaptonuria. Patient age ranged from 34 to 50 years. One patient who had severe arthropathy of the right hip joint along with subcutaneous nodules over both knees and Achilles tendons underwent total hip replacement. Another patient had intramedullary calcification of the femur. An additional patient had associated caries of the spine at L3, L4, and L5, with resolution of symptoms after antitubercular chemotherapy. Another patient had associated features of hyperthyroidism, which was an incidental finding. A further patient had nonunion fracture of the neck of the femur and underwent total hip replacement. The remaining 4 patients had typical features of low backache and arthritis of the large joints. The parents were nonconsanguineous, and only 2 patients had affected siblings. The remaining 7 patients had sporadic nonfamilial presentation. Diagnosis was established by typical clinical and radiologic findings and biochemical analysis. At 2 years of follow-up, both patients who underwent total hip replacement were normal, with no radiologic signs of loosening or lysis. Clinicians need a high index of suspicion and awareness to make the diagnosis of ochronosis. The current study is unique because of presentation with subcutaneous nodules in 1 patient and associated caries of the spine in another patient.
