Confinement homes are private institutions that provide full-time care for newborn babies and their respective postpartum mothers up to one month after delivery. An outbreak of fever and diarrhoea amongst newborns occurred in one such confinement home in Penang between the months of September to October 2004. An outbreak investigation was carried out including all babies, their respective mothers and workers in the home to determine the source of the outbreak and to institute control measures. Based on a working case definition of febrile illness with or without diarrhoea, 11 out of the 13 babies in the confinement home met the case definition. One hundred percent had symptoms of fever. 36.4% had symptoms of diarrhea and other respiratory conditions respectively. The attack rate of among babies in the confinement home was 90%. Echovirus 11 was isolated from 3 out of the 11 febrile cases. Echovirus 11 was isolated from the cerebrospinal fluid and stool of another baby at a private hospital that was epidemiologically linked to the first case. In conclusion, the outbreak of febrile illness amongst newborn babies in the affected confinement home was due to echovirus 11. The source was probably health-care associated with efficient transmission within the confinement home. The faecal-oral route was the most likely mode of transmission.

The use of antiepileptic drugs in pregnancy always presents challenges to doctors and their patients as it may have deleterious effects on the developing embryo. Lamotrigine is most commonly-prescribed drug among the newer antiepileptic drugs; hence, it has been selected for the present review. A number of studies pertaining to the safety of lamotrigine use during pregnancy have been reported, with differing results. Contradictory results have been reported in animals regarding lamotrigine teratogenicity, and human studies have also proven inconclusive. In many countries, human pregnancy registries are maintained to establish the safety of antiepileptic drugs during pregnancy, as all the different suggestions favour some over others, with specific antiepileptic combinations still being questioned. It is our hope that the present work may integrate the available disparate relevant facts into a directed effort towards minimising the risk of foetal compromise.

In most of the medical colleges in India, unclaimed bodies from various mortuaries reach the dissection hall; and here, the body donors club has yet to gain the desired dimensions. In spite of all the adverse circumstances, the cadaver and the dissection both have survived the most rigorous test of pedagological fitness--the test of time. Today, many of the Western countries have long donor waiting lists where cadavers are acquired as anatomical gifts or through body donor programmes. Thailand's approach to body donors offers a role model for resolving the present situation. The spirit of volunteerism reflects the drastic shift in public perception and a global change in approach is needed in the present time.

INTRODUCTIONWe aim to study and elucidate the safety profile of the antiepileptic doses of gabapentin during pregnancy, and to evaluate gabapentin-induced murine fetotoxicity at different dose levels.
METHODSA total of 60 pregnant mice, divided into 12 groups of five mice each, were exposed to gabapentin in four different doses of 0 (control), 113, 226, or 452 mg/kg body weight per day, at three different gestational stages including early gestation (1-6 days), mid-gestation (7-12 days), and late gestation (13-17 days). The pregnant mice were euthanized on day 18 of gestation, and foetuses were examined for teratogenic manifestations. Their brains were dissected and examined for gross changes, malformations, histological changes, and quantitative protein estimation.
RESULTSFoetal resorptions were observed in all treated groups with gabapentin administration at early gestation (1-6 days), and mid-gestation (7-12 days). On the other hand, growth retardation along with stunting in size of live foetuses were observed in all the mid-gestation (7-12 days), and late gestation (13-17 days) treated groups. Various gross malformations were observed with all the three doses (113, 226, and 452 mg/kg body weight per day) when gabapentin was administered at mid-gestation (7-12 days). The same trends were confirmed by gross and microscopic examination of brains along with quantitative protein estimation.
CONCLUSIONGabapentin should not be prescribed during pregnancy, as no therapeutic dose of gabapentin is safe during this period as far as the foetal well-being is concerned.

OBJECTIVE: To determine the effect of body mass index on postoperative complications and the performance of lymph node dissection in women undergoing laparoscopy or laparotomy for endometrial cancer. METHODS: Retrospective chart review of all patients undergoing surgery for endometrial cancer between 8/2004 and 12/2008. Complications graded and analyzed using Common Toxicity Criteria for Adverse Events ver. 4.03 classification. RESULTS: 168 women underwent surgery: laparoscopy n=65, laparotomy n=103. Overall median body mass index 36.2 (range, 18.1 to 72.7) with similar distributions for age, body mass index and performance of lymph node dissection between groups. Following laparoscopy vs. laparotomy the percent rate of overall complications 53.8:73.8 (p=0.01), grade > or =3 complications 9.2:34.0 (p<0.01), > or =3 wound complications 3.1:22.3 (p<0.01) and > or =3 wound infection 3.1:20.4 (p=0.01) were significantly lower after laparoscopy. In a logistic model there was no effect of body mass index (> or =36 and<36) on complications after laparoscopy in contrast to laparotomy. Para-aortic lymph node dissection was performed by laparoscopy 19/65 (29%): by laparotomy 34/103 (33%) p=0.61 and pelvic lymph node dissection by laparoscopy 21/65 (32.3%): by laparotomy 46/103 (44.7%) p=0.11. Logistic regression analysis revealed that for patients undergoing laparoscopy for stage I disease there was an inverse relationship between the performance of both para-aortic lymph node dissection and pelvic lymph node dissection and increasing body mass index (p=0.03 and p<0.01 respectively) in contrast to the laparotomy group where there was a trend only (p=0.09 and 0.05). CONCLUSION: For patients undergoing laparoscopy, increasing body mass index did not impact postoperative complications but did influence the decision to perform lymph node dissection.

Genes encoding the cellobiohydrolase enzyme (CBHI), designated as cbhI, were isolated from the basidiomycetes Auricularia fuscosuccinea, Pleurotus giganteus, P. eryngii, P. ostreatus, and P. sajor-caju. Initially, the fungal genomic DNA was extracted using a modified cetyltrimethyl ammonium bromide (CTAB) protocol and used as a DNA template. The cbhI genes were then amplified and cloned using the pGEM-T Easy Vector Systems. The sizes of these PCR amplicons were between 700~800 bp. The DNA sequences obtained were similar showing high identity to the cbhI gene family. These cbhI genes were partial consisting of three coding regions and two introns. The deduced amino acid sequences exhibited significant similarity to those of fungal CBHI enzymes belonging to glycosyl hydrolase family 7.

Testicular torsion is a common differential diagnosis of acute scrotal pain along with acute epididymo-orchitis, which may lead to testicular non-viability. Doppler ultrasound and testicular scintigraphy are two routinely used modalities for the assessment of testicular viability. However, in some cases, these investigations may prove inadequate in differentiating between the two entities with widely differing management. Here, we present a case of a 52-year-old male with questionable viability of testis, who was investigated initially using testicular scintigraphy and was further subjected to a regional 18F-FDG PET/CT scan, in view of inconclusive findings with the conventional modalities.

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: To investigate the efficacy of Ultrasonic Bone
Scalpel (UBS) in thoracic spinal stenosis (TSS) in
comparison to traditional technique.
Materials and methods: A total of 55 patients who had
undergone conventional surgery (Group A) are compared
with 45 patients of UBS (Group B) in TSS. The primary
outcome measure of Modified Japanese Orthopaedic
Association score (m JOA) with neurological complications
and dural injury were assessed. Secondary outcome
measures of total blood loss (TBL), time duration of surgery
(ORT) and length of hospital stay (LHS) were analysed.
Results: The pre-operative mJOA score 5.00(4.00-6.00) in
the group A and 5.00(4.00-6.00) in the group B improved to
7.00(7.00-8.00) in the group A and 9.00(9.00-10.00) in the
group B, respectively (P<0.001) at final average follow-up of
117.55 months for group A and 75.69 months in group B.
More significant grade of myelopathy improvement and
mJOA recovery rate (RR) were noted in group B. The TBL,
ORT and LHS were more favourable in group B as compared
to group A (p<0.0001). The group A had 9 (16.36%)
neurological deficits compared to 2 (4.44%) in group B
(p<0.001). Dural tears occurred in both groups (A=11, B=9).
It was more frequent and not repairable in group A but
without significant statistical difference.
Conclusions: UBS can reduce neurological deficits and
improve outcomes in TSS. Secondarily, reduced blood loss,
lesser surgical time and reduced LHS are significant added
advantages of this new technology.
