Age Estimation in Sportspersons From the Epiphyseal Fusion Around Wrist, Elbow, and Pelvic Joints.

Background Age estimation of an individual is an integral part of medicolegal work. Out of many scenarios for which age estimation is performed, competitive sports is the one emerging field where experts are consulted for providing accurate age of the athlete. Owing to the chances of deliberately increasing (padding) or decreasing (shaving) the age of the athlete for his own advantage, accurate age estimation is crucial. The Sports Authority of India (SAI) mandates age verification from experts prior to participation in sports events in various age group categories. One of the widely used methods of age estimation in athletes is the radiological examination of the ossification centers of bones. Methodology The study was performed on 134 athletes (72 males and 62 females) with an age range of 12-18 years old with due permission from the Sports Authority of India (SAI) for this study. These participants compete at state, national, and international levels in squash, handball, swimming, cricket, and judo in under-14, under-16, and under-19 age categories. X-rays of the wrists, elbows, and pelvis were analyzed using the Schmeling five-stage method for the fusion of ossification centers. Results A greater degree of correlation between the fusion stages of all regions of interest and chronological age was observed in males than in females. The highest correlation in both sexes is observed between the fusion score of the head of the radius and the age (R = 0.814 for males and R = 0.647 for females). The lowest correlation for both males and females is seen between the fusion score of the lateral epicondyle of the humerus and age (R = 0.754 for males and R = 0.441 for females). Multiple linear regression models showed a standard error of estimate (SEE) of 1.093 years for the elbow joint, 1.147 years for the wrist joint, 1.039 years for the pelvis joint, and 1.030 years for all three joints. Conclusion Regression models generated for estimating the age of sportspersons from the ossification centers of the elbow, wrist, and pelvis in the present study can be applied for the age estimation of individuals aged between 12 and 18 years. Future population-specific studies on the age estimation of sportspersons with greater sample sizes are necessary to validate the findings of the present study.

Antegrade Subperiosteal Temporalis Muscle Elevation and Posterior Retraction Technique Avoiding Muscle Incision for Pterional Craniotomy: A Technical Note.

Background: The current technique of pterional craniotomy involves temporalis muscle incision followed by retrograde elevation. Feasibility of antegrade temporalis muscle elevation without any direct incision over its bulk is evaluated. Objective: Incisionless "antegrade, subgaleal, subfascial, and subperiosteal elevation" of temporalis muscle preserves vascularity and muscle bulk. Posterior maneuvering of "bare" temporalis muscle bulk either above (out rolling) or under (in rolling) the scalp for pterional craniotomy is discussed. Material and Methods: Technique of antegrade, subfascial, subperiosteal elevation, and posterior rotation of temporalis muscle without incising in its bulk by "out rolling" or "in rolling" along the posterior aspect of the scalp incision was carried out in 15 cadavers and later in 50 surgical cases undergoing pterional craniotomy. Postoperatively, patients were evaluated for subgaleal collection and periorbital edema. Operated side cosmesis and temporalis muscle bulk was compared with nonoperated temporalis muscle at 6 months interval. Results: Antegrade subperiosteal dissection of temporalis muscle was possible in all cases. "In-rolling" or "out rolling" technique provided adequate surgical exposure during pterional craniotomy. Postoperative subgaleal collection and periorbital edema was prevented. Facial nerve paresis or temporalis muscle-related complications were avoided. Conclusion: Antegrade, subgaleal, subfascial, and subperiosteal dissection techniques of temporalis muscle elevation without any direct incision in its bulk enables neurovascular and muscle volume preservation. Posterior maneuvering of elevated temporalis muscle with "out rolling" or "in-rolling" technique is easy, quick, and provides adequate exposure during pterional craniotomy. Opening and closing of scalp layers without violating subgaleal space prevent postoperative subgaleal hematoma and periorbital edema.

Effect of Airborne Low Intensity Multi frequency ultrasound (ALIMFUS) on glycemic control, lipid profile and markers of inflammation in patients with uncontrolled type 2 diabetes: A multicentre proof of concept, randomized double blind Placebo controlled study.

BACKGROUND AND AIMS: Airborne Low Intensity Multi frequency Ultrasound (ALIMFUS) uses thermal and non thermal principal of ultrasound to facilitate transportation of drugs into the cells and it's metabolism. This is randomized, multi-center, Double Blind, Interventional, Placebo Controlled Study to evaluate efficacy and safety of ALIMFUS as an Add-on therapy to Oral Hypoglycemic Agent (OHA) in Type 2 DM. METHODS: Total 103/186 subjects completed the study and received 10 min either ALIMFUS therapy on alternate day for 90 days or placebo. Baseline and end of the study Lab parameters like HbA1c, blood sugars, Lipid Profile, Serum Hs-CRP, Serum Interleukin-6, Serum TNF-α, Serum homocysteine, Serum Vitamin D, Serum Leptin, Serum Adiponectin and Quality of Life score were assessed. RESULTS: At the end of study ALIMFUS group achieved greater (0.77 ± 1.13 vs 0.48 ± 0.79) but non-significant reduction in HbA1c. More subjects in ALIMFUS group (30.76% vs 27.45%) achieved HbA1c < 7%. Significant reduction in fasting and postprandial glucose noted in both groups whose baseline HbA1c was ≥8%. Significant reduction in lipid profile noted in ALIMFUS group compared to placebo. Insulin, adiponectin, CRP and homocysteine and quality of life were significantly better in ALMFUS group compared to baseline; but non-significant compared to placebo. No adverse events were associated with ALIMFUS. CONCLUSIONS: Thus, ALIMFUS could be novel technology in diabetes management for patient unable to achieve glycemic targets on combination therapy. However further exploratory long term studies are required to demonstrate its effective role as add-on therapy in diabetes management.

Safety and utility of kidney biopsy in patients with estimated glomerular filtration rate < 30 ml/min/1.73 m2.

AIM: Kidney biopsy (KBx) is the gold standard for evaluation of kidney disease, but is associated with a higher risk of complications in patients with reduced glomerular filtration rate (GFR). We studied the safety and utility of KBx in patients with eGFR <30 ml/min/1.73 m2 . METHODS: Consecutive adult patients with eGFR <30 ml/min/1.73 m2 , who were planned for a KBx and consented to participate were prospectively enrolled. Patients with solitary/transplant kidney or acute kidney injury were excluded. Haemoglobin was checked on the day of KBx and repeated 18-24 h later along with a screening ultrasound. Post-KBx complications were noted and their risk-factors analysed. The utility of the KBx was graded as effecting significant, some, or no change to subsequent management. RESULTS: Of the 126 patients included, 75% were male, 27.7% were diabetic, and the median eGFR was 13.5 ml/min/1.73m2 . Major complications occurred in 5.6%. Peri-renal haematomas were detected in 37.3%, and haematomas ≥2 cm were significantly more frequent in those with eGFR <15 ml/min/1.73 m2 (29.2% vs. 13%, p = .032). Dialysis was a risk factor, while pre KBx blood transfusion, diabetes and higher serum albumin were protective against any complication. KBx was more likely to make a significant difference in management in those with eGFR 15-29 ml/min/1.73m2 (44.1% vs. 11.1%, p < .001). Increasing age, lower serum creatinine and albumin were independently associated with KBx utility. CONCLUSION: KBx is relatively safe in severe kidney disease but its risk to benefit balance needs to be carefully considered when eGFR is <15 ml/min/1.73m2 .

Fatal Aspiration of Barium Sulfate in a Case of Myasthenia Gravis: A Case Report and Review of Literature.

Barium contrast radiography is a usual procedure performed for detecting lesions of the digestive tract using barium sulfate on X-ray irradiation. The aspiration of barium contrast is an uncommon but well-documented complication occurring accidentally during examinations of the upper gastrointestinal system using contrast media. Certain conditions that affect the anatomical and functional integrity of the oropharynx and esophagus can be predisposing factors. Barium is an inert material that can cause symptoms varying from an asymptomatic mechanical obstruction to severe respiratory distress that can result in death when aspirated. Sudden death due to aspiration of barium is rarely reported in the literature. We report a case of a 50-year-old female who suddenly developed difficulty in breathing, followed by loss of consciousness during barium swallow procedure due to aspiration of barium contrast. She could not be revived and died within a few minutes of the episode. The predisposing factor was the weakness of the muscles of deglutition due to myasthenia gravis. We also reviewed the literature available on cases resulting from the aspiration of barium sulfate during the barium study procedures. We considered the factors like the age, indications, the distribution of barium in the lungs, clinical presentation, the period of survival, and cause of death. We came across only four cases of death within 24 h following the aspiration of barium. This case report and review of literature emphasize the importance of consideration of predisposing factors before conducting barium contrast radiography and also the possibility of sudden death.

Age estimation and comparison by dental and skeletal maturity in the age range of 9-18 years in the Mumbai region.

BACKGROUND: Age estimation is crucial in the identification of juveniles in conflicts with law, survivor of sexual assault, sportsperson, and civil cases. AIMS: To estimate and compare the age (9-18 years) by dental and skeletal maturity in the Mumbai region. SETTINGS AND DESIGN: This was a cross-sectional study. MATERIALS AND METHODS: A total of 70 cases from 9 to 18 years of age were studied in 1 year in the urban population of the Mumbai region. Among 70 cases, 45 were males and 25 were females. Orthopantomogram and elbow joint radiographs were taken to assess the dental age through modified Demirjian's method and the radiological age through Sangma et al. staging method, respectively. STATISTICAL ANALYSIS: Data were analyzed using SPSS Statistics Version 26; descriptive statistics and regression statistics were used in the study. RESULTS: Dental age by Demirjian's method in males with standard deviation was 15.25 (2.17), with a mean difference of 1.08 and significant P = 0.03. However, in females, dental age by Demirjian's method with standard deviation was 14.30 (1.94) with a mean difference of 0.74 and insignificant P = 0.07. Interclass correlation coefficient of dental age with chronological age, in males and females, showed 0.85 and 0.87 correlation, respectively. Correlation between the skeletal maturity and the dental age was reflected by the association of Demirjian stage 9 in the second molar with radiological stage 5 in males and stage 4 in females. CONCLUSIONS: It was concluded that Demirjian's method shows a significant correlation and P value for the age estimation in males of the Mumbai region.

Management of Chronic Subdural Hematoma: Burr Hole versus Twist Drill - A Prospective Study.

INTRODUCTION: Incidence of chronic subdural hematoma (CSDH) is about 5/100,000/year in the general population and still rising. Two surgical techniques, namely, burr-hole evacuation (BHE) versus twist-drill evacuation (TDE) are commonly used to manage such patients but the preferred surgical method continues to attract debate, and the time for an evidence-based approach is now overdue. In vogue with recent trends, a minimally invasive surgical approach is considered as best; therefore, we tried to establish the hypothesis that TDE is as safe and as effective as BHE for CSDH treatment. MATERIALS AND METHODS: A prospective, randomized, controlled study including forty patients was conducted. The primary outcome variable studied was clinically significant recurrence rate. The secondary outcome variables in postoperative period and follow-up assessment of the patients include Glasgow coma scale (GCS), Markwalder grade, postoperative complication, and operative mortality rate. RESULTS: In our study, results of BHE seem to be superior than TDE in terms of recurrence rate (5% vs. 15%), complication rate (15% vs. 20%), and mean Markwalder neurological grading score and mean GCS at time of discharge (0.16 vs. 0.45 and 14.95 vs. 14.65, respectively). TDE seems to be better than BHE in terms of duration of hospital stay (7.4 vs. 8.05). However, these differences were not statistically significant. TDE is having the advantage of being performed at bedside without the need of monitored anesthesia and anesthetist, time saving, and least invasive. Overall results were comparable across both techniques without any significant difference. CONCLUSION: Although both techniques appear to be similar in respect of their primary and secondary outcome variables, but TDE is having the advantage of being performed at bedside without the need of monitored anesthesia and anesthetist, time saving, and small incision.

PCR targeting IS6110 in diagnosing tuberculosis in children in comparison to MGIT culture.

BACKGROUND: Diagnosis of tuberculosis (TB) in children is difficult in children especially in extrapulmonary tuberculosis (EPTB). This study was conducted to evaluate the use of polymerase chain reaction (PCR) targeting IS6110 in the diagnosis of TB in children with pulmonary TB and EPTB and also to compare its performance with MGIT 960 culture and conventional microscopy. METHODS: A total of 142 cases (50 pulmonary, 92 extrapulmonary) of suspected TB patients <15 years of age were included in the study. The clinical specimens obtained from these cases were subjected to Ziehl-Neelsen staining (ZN), MGIT 960 TB culture and PCR targeting insertion sequence IS6110. Sensitivity and specificity of PCR were calculated in pulmonary and extrapulmonary specimens. The results were compared to MGIT culture. RESULTS: PCR targeting IS6110 sequence had sensitivity of 69.01% in various clinical specimens which was significantly more than MGIT culture showing a sensitivity of 47.41% (p<0.05). Sensitivity of PCR IS6110 in extrapulmonary specimens was 65.21% which was lower than sensitivity in pulmonary specimens (76%) but was not statistically significant (p>0.05). CONCLUSIONS: Diagnostic efficacy of PCR IS6110 in pulmonary and extrapulmonary TB cases was similar. PCR using IS6110 primer had significantly better efficiency than MGIT culture in diagnosing TB in children.

Comparison of Early Mechanical and Infective Complications in First Time Blind, Bedside, Midline Percutaneous Tenckhoff Catheter Insertion with Ultra-Short Break-In Period in Diabetics and Non-Diabetics: Setting New Standards.

♦ BACKGROUND: There are no large studies that have examined ultra-short break-in period with a blind, bedside, midline approach to Tenckhoff catheter insertion. ♦ METHODS: Observational cohort study of 245 consecutive adult patients who underwent percutaneous catheter insertion for chronic peritoneal dialysis (PD) at our center from January 2009 to December 2013. There were 132 (53.9%) diabetics and 113 (46.1%) non-diabetics in the cohort. ♦ RESULTS: The mean break-in period for the percutaneous group was 2.68 ± 2.6 days. There were significantly more males among the diabetics (103 [78%] vs 66 [58.4%], p = 0.001). Diabetics had a significantly higher body mass index (BMI) (23.9 ± 3.7 kg/m2 vs 22.2 ± 4 kg/m2, p < 0.001) and lower serum albumin (33.1 ± 6.3 g/L vs 37 ± 6 g/L, p < 0.001) compared with non-diabetics. Poor catheter outflow was present in 6 (4.5%) diabetics and 16 (14.2%) non-diabetics (p = 0.009). Catheter migration was also significantly more common in the non-diabetic group (11 [9.7%] vs 2 [1.5%], p = 0.004). Primary catheter non-function was present in 17(15%) of the non-diabetics and in 7(5.3%) of the diabetics (p = 0.01). There were no mortality or major non-procedural complications during the catheter insertions. Among patients with 1 year of follow-up data, catheter survival (93/102 [91.2%] vs 71/82 [86.6%], p = 0.32) and technique survival (93/102 [91.2%] vs 70/82 [85.4%], p = 0.22) at 1 year was comparable between diabetics and non-diabetics, respectively. ♦ CONCLUSIONS: Percutaneous catheter insertion by practicing nephrologists provides a short break-in period with very low mechanical and infective complications. Non-diabetic status emerged as a significant risk factor for primary catheter non-function presumed to be due to more patients with lower BMI and thus smaller abdominal cavities. This is the first report that systematically compares diabetic and non-diabetic patients.

Retinal arterial plaques in acquired immunodeficiency syndrome.

The authors report the unusual observation discrete plaque like excrescencies along the retinal arterial wall in a young patient with acquired immunodeficiency syndrome. Though bilateral, in the right eye there was severe arteriolar narrowing and so these plaques were less identifiable. Fluorescein angiography did not reveal any arteriolar occlusion or areas of capillary occlusion in both eyes. There were no other signs of HIV associated microangiopathy and the patient did not have any concurrent cardiovascular or hematological abnormality. The cause of these plaques remains unexplained and we conjecture that they could represent macro immune-complex deposition along the arteriolar walls.

Comparative evaluation of 18F-FDOPA, 13N-AMMONIA, 18F-FDG PET/CT and MRI in primary brain tumors - A pilot study.

AIM: To determine the diagnostic reliability of 18F-FDOPA, 13N-Ammonia and 18F-FDG PET/CT in primary brain tumors and comparison with magnetic resonance imaging (MRI). MATERIALS AND METHODS: A total of 23 patients, 8 preoperative and 15 postoperative, undergoing evaluation for primary brain tumors were included in this study. Of them, 9/15 were operated for high grade gliomas (7/9 astrocytomas and 2/9 oligodendrogliomas) and 6/15 for low grade gliomas (5/6 astrocytomas and 1/6 oligodendroglioma). After PET study, 2 of 8 preoperative cases were histopathologically proven to be of benign etiology. 3 low grade and 2 high grade postoperative cases were disease free on 6 months follow-up. Tracer uptake was quantified by standardized uptake values (SUV(max)) and the SUV max ratio of tumor to normal symmetrical area of contra lateral hemisphere (T/N). 18F-FDOPA uptake was also quantified by SUV(max) ratio of tumor to striatum (T/S). Conventional MR studies were done in all patients. RESULTS: Both high-grade and low-grade tumors were well visualized with 18F-FDOPA PET. Sensitivity of 18F-FDOPA PET was substantially higher (6/6 preoperative, 3/3 low grade postoperative, 7/7 high grade postoperative) than with 18F-FDG (3/6 preoperative, 1/3 low grade postoperative, 3/7 high grade postoperative) and 13N-Ammonia PET (2/6 preoperative, 1/3 low grade postoperative, 1/7 high grade postoperative). FDOPA was equally specific as FDG and Ammonia PET in operated cases but was falsely positive in two preoperative cases. Sensitivity of FDOPA (16/16) was more than MRI (13/16). CONCLUSION: 18F-FDG uptake correlates with tumor grade. Though 18F-FDOPA PET cannot distinguish between tumor grade, it is more reliable than 18F-FDG and 13N-Ammonia PET for evaluating brain tumors. 18F-FDOPA PET may prove to be superior to MRI in evaluating recurrence and residual tumor tissue. 13N-Ammonia PET did not show any encouraging results.

Comparative study of (18)F-DOPA, (13)N-Ammonia and F18-FDG PET/CT in primary brain tumors.

AIM: To determine the diagnostic reliability of (18)F-FDOPA, (13)N-Ammonia and F18-FDG PET/CT in primary brain tumors. We evaluated the amino acid and glucose metabolism of brain tumors by using PET with (18)F-FDOPA, (13)N-Ammonia and F18-FDG PET/CT. MATERIALS AND METHODS: Nine patients undergoing evaluation for brain tumors were studied. Tracer uptake was quantified by the use of standardized uptake values and the ratio of tumor uptake to normal identical area of contra lateral hemisphere (T/N). In addition, PET uptake with (18)F-FDOPA was quantified by use of ratio of tumor uptake to striatum uptake (T/S). The results were correlated with the patient's clinical profile. RESULTS: Both high-grade and low-grade tumors were well visualized with (18)F-FDOPA. The sensitivity for identifying tumors was substantially higher with (18)F-FDOPA PET than with F18-FDG and (13)N-Ammonia PET as determined by simple visual inspection. The sensitivity for identifying recurrence in low grade gliomas is higher with (13)N-Ammonia than with F18-FDG. CONCLUSION: (18)F-FDOPA PET is more reliable than F18-FDG and (13)N-Ammonia PET for evaluating brain tumors.

Rare presentation of fungal orbital cellulitis in an immunocompetent infant.

A 3-month-old infant presented with unilateral proptosis. Ophthalmic and physical examinations, computed tomography, and histopathologic examination of a biopsy specimen were performed. Histopathologic examination confirmed fungal orbital cellulitis. The patient responded to 6 weeks of antifungal therapy. Fungal orbital cellulitis should be included in the differential diagnosis for infants with proptosis.

Precaruncular periosteal anchor of medial rectus, a new technique in the management of complete external third nerve palsy.

Management of complete external third nerve palsy is a challenge to a strabismologist; as four of six extra-ocular muscles are affected, it leaves eye in fixed hypotropic and exotropic position (Srivastava et al., 2004). Although numerous surgical procedures have been described, none has been found to be ideal for all cases. Horizontal supramaximal recession-resection procedure may work in cases having some function of medial rectus (Harley, 1980). In cases of complete external palsy, anchoring of globe to periosteum of medial orbital wall using different structures has been described (Villasenor Solares et al., 2000; Bicas, 1991; Salazar-Leon et al., 1998), as recession-resection may result in large residual deviation and/or eye drifts back to abducted position due to unopposed lateral rectus action (Von Noorder, 1996). These anchoring procedures are with associated problems of skin incision, thigh surgery or loss of superior oblique function (Villasenor Solares et al., 2000; Bicas, 1991; Salazar-Leon et al., 1998). We describe a new and safe technique for management of complete external third nerve palsy by anchoring insertion of medial rectus to medial wall periosteum, posterior to posterior lacrimal crest, along with supra maximal recession of lateral rectus.

Glial heterotopia of the orbit and extranasal region: an unusual entity.

Glial heterotopia or the occurrence of isolated non-teratomatous extracranial glial tissue is rare. Most of the reported cases of this entity arise in the nose. Herein a rare case of heterotopic glial tissue in the orbit and extranasal region without bony defect is described.

Lipoid proteinosis: a rare disorder with pathognomonic lid lesions.

Lipoid proteinosis is a rare disorder seen even more rarely by ophthalmologists. The interesting clinical and histopathological features of this disease are described in a brother and sister who presented predominantly with lid lesions, without any systemic complaints. Knowledge of the typical lid lesions may help to diagnose this disorder.
