OBJECTIVEParaplegia due to traumatic spinal cord injuries is one of the devastating effects of dorsolumbar vertebral fractures. Treatment modalities for such fractures, such as stabilization, have no effect on the neurological recovery. Thus, various pharmacological and biological treatment modalities have been used. The more recent trend of using autologous stem cells from the iliac crest has been used in some clinical trials with varying success. Thus, more clinical studies are required to study the effect of this novel approach
METHODSThis is a prospective hospital-based cohort study (level IV). The study was conducted in the Dept. of Orthopaedics, University College of Medical Sciences and GTB Hospital, Delhi from November 2010 to March 2012. Ten patients who had sustained traumatic dorsolumbar vertebral fractures with complete paraplegia were recruited for this study. Under suitable anaesthesia, at the beginning of surgery, 100 ml of bone marrow was aspirated. This was centrifuged and buffy coat isolated and then transferred into a sterile tube and sent to the operating room on ice packs. After surgical decompression and stabilization, the buffy coat isolate was injected into the dural sleeve at the site of the injury using a 21G needle. All the patients were evaluated for neurological improvement using the American Spinal Injury Association (ASIA) score and Frankel grade at 6 weeks and 3 months postoperatively.
RESULTSThe evaluation at 6 weeks showed some improvement in terms of the ASIA scores in 2 patients but no improvements in their Frankel Grade. The other 8 patients showed no improvements in their ASIA scores or their Frankel Grades. The current pilot study has shown that there has been no improvement in most of the recipients of the transplant (n=8). Some patients (n=2) who did show some improvement in their sensory scores proved to be of no significant functional value as depicted by no change in their Frankel Grades.
CONCLUSIONThe outcome of current study shows that although this modality of treatment is safe for the patients, it provides no additional benefits on improvement of quality of life among these patients.

Xylophagous termites are capable of degrading lignocellulose by symbiotic gut microorganisms along with the host’s indigenous enzymes. Therefore, the termite gut might be a potential niche to obtain natural yeasts with celluloytic, xylanolytic and ethanologenic traits required for bioethanol production from lignocellulosic biomass. In this study, we cultured 79 yeasts from three different termites viz. Coptotermes heimi, Odontotermes javanicus and Odontotermes obesus. After suitable screening methods, we identified 53 yeasts, which belonged to 10 genera and 16 different species of both ascomycetous and basidiomycetous yeasts. Most yeasts in the present study represent their first-ever isolation from the termite gut. Representative strains of identified yeasts were evaluated for their cellulolytic, xylanolytic, and ethanologenic abilities. None of the isolates showed cellulase activity; 22 showed xylanolytic activity, while six produced substantial quantities of ethanol. Among xylanolytic cultures, Pseudozyma hubeiensis STAG 1.7 and Hannaella pagnoccae STAG 1.14 produced 1.31 and 1.17 IU of xylanase. Among ethanologenic yeasts, the strains belonging to genera Candida and Kodamaea produced high amount of ethanol. Overall, highest ethanol level of 4.42 g/L was produced by Candida tropicalis TS32 using 1% glucose, which increased up to 22.92 g/L at 35 °C, pH 4.5 with 5% glucose. Fermentation of rice straw hydrolysate gave 8.95 g/l of ethanol with a yield of 0.42 g/g using the strain TS32. Our study highlights the gut of wood-feeding termites as a potential source of diverse yeasts that would be useful in the production of xylanase and bioethanol.

Introduction: The movement and steadiness of the shoulder
joint is due to both the dynamic and static stabilisers.
Recurrent anterior shoulder instability is common due to the
Bankart lesion or the Hill Sachs lesion. The bone loss and
soft tissue failure due to these lesions causing instability is
well compensated by Latarjet procedure which acts by triple
blocking effect of the bone graft, the sling effect of the
conjoint tendon of subscapularis and the ligament of the
coracoacromial ligament stump.
Materials and methods: Middle-aged patients with
recurrent anterior shoulder dislocation and a mid-range
instability on clinical assessment with an isolated glenoid
bone loss of 20% or Bankart lesion with engaging Hill Sachs
lesion were selected for the study. The surgical procedure
included a subscapularis split to expose the glenoid. The
coracoid graft harvested was prefixed with Kirschner wires
and placed flush over the glenoid ensuring no medial or
lateral overhang and fixed with 4.0mm cancellous screws
with the washer. The functional outcome was measured with
the ROWE score and ASES score and the movements were
evaluated.
Results: A total of 24 patients fulfilled the inclusion criteria.
Post-operatively at final follow-up, the mean ROWE score
was 97.08 ±8.45 and the mean ASES score was 94.4±9.10.
One patient had screw breakage as a complication and
another had restriction of movement which was managed
with physiotherapy.
Conclusion: Open Latarjet is an effective procedure for
recurrent anterior shoulder instability in non-athletic middleaged patients as a excellent functional outcome was achieved
with this technique. We therefore recommend open Latarjet
as an alternative to arthroscopic treatment in developing
countries where patient affordability and the availability of
the resources are the issues.

Introduction: The aim of this study is to assess the
outcomes of ala carte posteromedial release in children over
two years of age who were not responding to the Ponseti
method of treatment of idiopathic clubfoot.
Materials and Methods: A retrospective observational
study from September 2013 to August 2015 was conducted
at a tertiary level medical teaching institution. The clubfeet
were classified according to the Harold and Walker
classification. Radiographic parameters assessed were the
talocalcaneal angle (AP, lateral), talus-first metatarsal angle
(AP, lateral) and calcaneal-fifth metatarsal angle. The scar
and the functional score, according to Laaveg and Ponseti,
were evaluated as outcome measures at the final follow-up.
Results: Twenty-four children with a mean age of 43.7 ±
24.7 months were enrolled in the study. There was a total of
36 clubfeet: 21 (65.6%) with a poor functional outcome; 12
(37.4%) with excellent to good scar in both horizontal and
vertical components. There was a statistical significance
between the pre-operative and post-operative radiological
parameters (p<0.05). None of the patients presented with any
limitation of activities of daily living despite the poor
functional outcome in many of the children. There was no
significant association between the qualities of scar
(horizontal, vertical) and the functional outcome with age at
presentation, pre-operative Harold and Walker classification
and pre-operative radiographic angles.
Conclusion: Surgical intervention in terms of ala carte
posteromedial soft tissue release could not produce a good
outcome over four years in CTEV. The threshold for surgery
in CTEV should be high, given the poor results.

ABSTRACT
Thalassemia is an inherited disorder that involves abnormal haemoglobin formation. This cross-sectional
study with universal sampling was conducted from May 2018 to January 2019 to evaluate the oral
health status of children with thalassaemia. The sample consisted of 54 transfusion-dependent patients
between the ages of 3–17 years old, who were registered at the paediatric day-care centre of Hospital
Melaka. Oral health status was evaluated which included soft tissue examination, recording of dental
caries, malocclusion and oral hygiene status of the children, while their parents answered a pre-validated
self-administered questionnaire on sociodemographic and oral health practices and attitudes. The mean
deft (decayed, exfoliated and filled teeth) among the 3–5 years old was 6.71±6.07. The mean DMFT
(decayed, missing and filled teeth) was 3.00±3.94 among the 13–17 years old and 1.12±1.42 among
the 6–12 years old. Most of the 3–5 years old children exhibited good oral hygiene (71.4%). Dentofacial
findings among the 3–5 years old were increased overjet (35.7%) and open bite (28.6%) predominantly.
Fractured teeth (69.2%), increased overjet (46.2%) and discolouration (23.1%) were the common
dentofacial findings among the 6–12 years old while increased overjet (71.4%), soft tissue lesions
(57.1%) and posterior crossbite (28.6%) were seen among the 13–17 years old. In this cohort of children
with thalassaemia, the prevalence of dental caries was high in preschool children and older children.

Introduction: The present inquiry seeks to investigate
whether the current regimens of QSEs (QuadricepsStrengthening Exercises) aggravate the disease while
mitigating symptoms.
Materials and methods: A comparative study was
conducted on 32 patients with medial compartment
osteoarthritis of knees. While the neutral group of 16 patients
was constituted of those with an anatomical-lateral-femorotibial-angle (aFTA) 176-180º, varus group comprised an
equal number of patients with an aFTA >180º. A home-based
12-week strength-training program involving weekly visits
to hospital for supervised sessions was administered. The
outcome measures were visual-analog-scale (VAS), medial
patello-femoral joint tenderness (MPFJT), time-up-and-gotest (TUGT), stair-climb test, step test, WOMAC, IKDC
scores, aFTA, hip-knee-ankle (HKA) angle, lateral-tibiofemoral-joint-separation (LTFJS), and horizontal-distancefrom-centre-of-knee-to-Mikulicz-line.
Results: There was a significant increase in quadriceps
strength (p<0.01) in both groups. Values for neutral group
with VAS score (p=0.01), MPFJT (p=0.01), TUGT (p=0.01),
timing of the stair climb test (p=0.01), WOMAC (p<0.01),
and IKDC (p=0.03) were better compared to varus group
with VAS score (p=0.13), MPFJT (p=0.03), TUGT (p=0.90),
timing of stair climb test (p=0.68), WOMAC (p<0.02), and
IKDC (p=0.05). Varus group also showed an increase in
aFTA and LTFJS in 12 patients, increase in HKA in 11, and
increase in horizontal distance from the centre of knee to the
Mikulicz line in 7 patients.
Conclusion: The present study brings to the fore the
paradoxical role played by QSEs in management of medial
knee OA. While there is a radiological progression of the
disease in both neutral and varus mal-aligned knees more so
in the latter than the former.
