Use of Ilizarov Device to Gain Early Range of Motion in the Treatment of Pediatric Talus Body Fractures: A Series of Four Cases and Literature Review

BackgroundTalus fractures are rare in children but can lead to severe outcomes if untreated. The Ilizarov external fixator has been used in the treatment of a variety of lower extremity pathologies. The purpose of this study was to investigate the clinical outcomes of talus body fractures treated with the Ilizarov external fixator.Case PresentationFour male pediatric patients (age range, 5–11 years) with talus body fractures who were treated by open reduction and internal fixation combined with Ilizarov external fixator between November 2015 and April 2016 were reviewed. Mean follow‐up period was 4 years (range, 4–5). Clinical outcome was evaluated using the clinical rating scale of the American Orthopaedic Foot and Ankle Society (AOFAS). All four patients achieved good to excellent results at the last follow‐up. None of the patients developed avascular necrosis. One patient developed automatic fusion of tibiotalar joint.ConclusionUse of the Ilizarov external fixator to gain early range of motion is a valuable option for treatment of talus body fractures in children.     

Thrombocytopenia in children with malaria–A study from coastal Karnataka,India

ObjectiveTo study the occurrence and severity of thrombocytopenia in children with malaria.MethodsIt was a retrospective study, done at Fr Muller Medical College Hospital Mangalore, in Karnataka, India. Data regarding all positive cases of malaria < 15 years admitted in the hospital between January 2010 to June 2011 were obtained. Patients were further assessed for thrombocytopenia and its severity. Data were analysed by Chi square test using SPSS version 13.0.ResultsA total of 159 cases were included in the study with a mean age of presentation of 9 years. Plasmodium vivax was identified in 106 (66%) patients while Plasmodium falciparum in 26 (16%) and mixed infection in 27 (18%) patients. Thrombocytopenia was observed in 113 (71%) cases, of which 35 (31%) cases had mild, 49 (43%) cases moderate and 29 (26%) cases had severe thrombocytopenia. Thrombocytopenia was equally found in vivax and falciparum infection with no significant difference in severity between vivax and falciparum species.ConclusionsThrombocytopenia is frequently seen in malaria and it is not dependent on type of malaria. In any acute febrile illness, thrombocytopenia should alert one to the possibility of malaria.     

Discrepancy in the length of the tibiae in unilateral congenital dislocation of the hip.

We measured discrepancy in the length of the tibiae in cases of unilateral congenital dislocation of the hip (CDH) in 10 patients. The mean shortening of the tibia on the affected side was 1 cm and was not related to the severity of the dislocation. Patients who are about to undergo total hip arthroplasty for CDH should be warned that the operation is unlikely to restore normal leg length.     

Changing trends of an endemic trauma

The incidence of severe burn is extremely high in the Low and Middle Income Countries with an estimated 90% of the world incidence of which 50% is in South East Asia. Through an earlier analysis of 11,196 burn admission over 8 years (1993–2000—Phase I) to our burn unit we established the endemic nature of the injury [Ahuja RB, Bhattacharya S. An analysis of 11,196 burn admissions and evaluation of conservative management techniques. Burns 2002;28:555–61]. A continued analysis of 5566 burn admissions over the next 7 years (2001–2007—Phase II) and its comparison with the Phase I reveals a significant change in the epidemiological profile. The average yearly admissions have fallen by 43.14%, from 1399.5 patients in Phase I to 795.14 patients in Phase II. This fall in average yearly admissions is predominant in the age group 16–35 years (52.61% decline) and 36–55 years (46.51% decline). The overall female to male ratio has also changed from 1.26:1 to 0.91:1. However, the overall mean %TBSA burn has reduced only mildly from 49.12% TBSA in Phase I to 44.39% in Phase II. During Phase II there was also a significant decline of 46.93% and 56.25% in the yearly admission of flame and scald burn respectively. Non-intentional incidents still remain the main mode of injury accounting for 87.12% in Phase I and 89.89% in Phase II. But, the yearly admissions of non-intentional burns fell from 1219.25 in Phase I to 714.71 in Phase II, which is a significant drop of 41.38%. Kitchen continues to dominate as the main location for flame incidents, but the yearly admission rate from kitchen accidents dropped from 897.5 patients in Phase I to 368.43 patients in Phase II. At the same time, liquefied petroleum gas (LPG) leaks which accounted for only 0.72% of all kitchen accidents in Phase I rose to 10.74% in Phase II. Another redeeming feature is the reduction in overall mortality from 51.8% in Phase I to 40.20% in Phase II. Interestingly, a very significant negative correlation exists (being significant at 0.01 level—2 tailed) between burn admissions and the yearly per-capita income of Delhi, from 1993 to 2005, to prove that the incidence and profile of burns directly reflects the economic development of the society. We see this as the first long term study from a burn unit of a developing country to directly reflect this association of burn incidence and its changing profile with economic prosperity.     

Role of F-18 FDG PET/CT in assessing bone marrow involvement in pediatric Hodgkin’s lymphoma

Objectives

The aim of the current study was to assess the utility of F-18-fluoro-2-deoxy-d-glucose (F-18 FDG) positron emission tomography/computed tomography (PET/CT) in assessing bone marrow involvement (BMI) compared to bone marrow biopsy (BMB) in initial staging of Hodgkin’s lymphoma (HL) in pediatric patients.

Methods

Data of 38 pediatric patients (mean age 9.8 years, range 3–18 years) with HL were analyzed for the involvement of bone marrow. All patients underwent non-contrast F-18 FDG PET/CT study. BMB was done in 31 patients from the bilateral iliac crests. Scans were interpreted by two nuclear medicine physicians blinded to the details of BMB.

Results

Of the 31 patients who underwent BMB, 5 patients had lymphomatous involvement on BMB. PET/CT was positive in four of these five patients. In 26 patients negative on BMB, PET was negative in 23 patients and positive in 3 patients for BMI. The sensitivity and negative predictive value of F-18 FDG PET/CT was 87.5 and 96 %, respectively, for BMI.

Conclusions

F-18 FDG PET/CT can predict BMB results with high accuracy. F-18 FDG PET/CT may be used at initial staging of pediatric Hodgkin’s lymphoma as it uncovers unsuspected BMI and BMB may be omitted in patients with PET-positive BMI.     

An unusual cervical chordoma: CT and MRI

We report CT and MRI findings of an unusual cervical chordoma. CT showed only minimal bony destruction with a lobulated prevertebral mass. Sagittal MRI, however, clearly demonstrated a lesion involving the body of C2 extending prevertebrally and into the spinal canal.     

Incidence of Extensor Digitorum Brevis Manus Muscle

The extensor digitorum brevis manus, a supernumerary muscle in the fourth extensor compartment of the dorsum of the wrist, is a relatively rare anomalous muscle. Extensor digitorum brevis should be included in the differential diagnosis of soft tissue masses on the dorsal aspect of the hand as it may mimic cystic, neoplastic, inflammatory, and infectious masses arising in the dorsum of the wrist. Seventy-two upper limbs of male and female cadavers were dissected and examined to study the pattern of extensor tendons of the index finger. In the present study, we observed three cases (4.2%) of the extensor digitorum brevis manus on the left side. In one cadaver (0.72%), there was an additional tendon arising from the extensor indices which was inserted to the radial side of the dorsal digital expansion of the index finger. The extensor digitorum brevis manus muscle (EDBM), an anatomic variant of the extensor muscle of the dorsum of the hand, is found in approximately 2% to 3% of the population. This variation is, therefore, clinically and surgically relevant because the EDBM may be the only muscle responsible for the independent extension of the second digit. The aim of the present study is to report the incidences of this muscle thereby creating awareness of its existence and of its characteristic appearance to surgeons.     

The effect of weight loss after bariatric surgery on albuminuria

BACKGROUND: Bariatric surgery achieves long-term weight loss in obese adults with improvement of diabetes and hypertension. Little is known about the effect of this weight loss on renal parameters. METHODS: We performed a retrospective study of 94 obese adults who had Roux-en-Y gastric bypass surgery with a mean 12-month follow-up. Baseline (preoperative) mean age was 49 years, 76% were female, 37 had blood pressure (BP) >or= 140/90 mmHg and 32 had Type 2 diabetes. 73 patients had normoalbuminuria (urine albumin creatinine ratio (ACR) <30 mg/g) while 21 had microalbuminuria (ACR 30<300 mg/g). RESULTS: At follow-up (postoperative), we observed a decrease in mean body weight (133.6 to 97.9 kg, p<0.0001), mean hemoglobin A1c (6.3 to 5.6%, p<0.0001) and mean systolic blood pressure (132.7 to 114.0 mmHg, p<0.0001). There was a significant reduction in ACR (median with interquartile range) from 9.5 (5-28) to 5.5 (3-10) mg/g, p < 0.0001. Fewer patients had microalbuminuria (22.2 to 6.2%, p=0.004) after surgery. Subgroup analysis revealed that significant decrease in ACR was present in the 32 patients with diabetes (16.5 (5-67) to 6.0 (4-11) mg/g, p=0.001) and in the 37 patients with metabolic syndrome (8.0 (5-16) to 6.0 (3-13) mg/g, p=0.012), while 25 patients with obesity alone had a lower ACR (6.5 (4-13) to 4.5 (3-8) mg/g, p=0.270). Multiple linear regression analysis showed change in hemoglobin A1c (p=0.011) and baseline level of ACR (p<0.0001) to be significantly associated with change in ACR. CONCLUSION: We conclude that obese adults have a reduction in albuminuria after surgical weight loss, most importantly in patients with diabetes or metabolic syndrome.
