Neonatal deaths in Cambodia: findings from a community-based mortality review.

OBJECTIVES: The aim of this study was to describe potential factors contributing to neonatal mortality in Takeo, Cambodia through assessment of verbal autopsies collected following newborn deaths in the community. The mortality review was nested within a trial of a behavioral intervention to improve newborn survival, and was conducted after the close of the trial, within the study setting. The World Health Organization standardized definition of neonatal mortality was employed, and two pediatricians independently reviewed data collected from each event to assign a cause of death. RESULTS: Thirteen newborn deaths of infants born in health facilities participating in a community based, behavioral intervention were reported during February 2015-November 2016. Ten deaths (76.92%) were early neonatal deaths, two (15.38%) were late neonatal deaths, and one was a stillbirth. Five out of 13 deaths (38.46%) occurred within the first day of life. The largest single contributor to mortality was neonatal sepsis; six of 13 deaths (46.15%) were attributed to some form of sepsis. Twenty-three percent of deaths were attributed to asphyxia. The study highlights the continuing need to improve quality of care and infection prevention and control, and to fully address causes of sepsis, in order to effectively reduce mortality in the newborn period.

Remission of post-transplant focal segmental glomerulosclerosis with angiotensin receptor blockers.

Recurrence of focal segmental glomerulosclerosis (FSGS) is common after kidney transplantation. Plasmapheresis (PP) is considered to be the most effective treatment; however, results are variable and relapse is common after stopping plasmapheresis. Here, we report an unusual case of recurrent FSGS, who achieved complete remission with angiotensin receptor blocker therapy.

ABO-incompatible renal transplantation in developing world - crossing the immunological (and mental) barrier.

ABO incompatibility has been considered as an important immunological barrier for renal transplantation. With the advent of effective preconditioning protocols, it is now possible to do renal transplants across ABO barrier. We hereby present a single center retrospective analysis of all consecutive ABOi renal transplants performed from November 2011 to August 2014. Preconditioning protocol consisted of rituximab, plasmapheresis and intravenous immunoglobulin (IVIG) and maintenance immunosuppression consisted of tacrolimus, mycophenolate sodium, and prednisolone. The outcome of these ABOi transplants was compared with all other consecutive ABO-compatible (ABOc) renal transplants performed during same time. Twenty ABOi renal transplants were performed during the study period. Anti-blood group antibody titer varied from 1:2 to 1:512. Patient and graft survival was comparable between ABOi and ABOc groups. Biopsy proven acute rejection rate was 15% in ABOi group, which was similar to ABOc group (16.29%). There were no antibody-mediated rejections in ABOi group. The infection rate was also comparable. We conclude that the short-term outcome of ABOi and ABOc transplants is comparable. ABOi transplants should be promoted in developing countries to expand the donor pool.

Paired kidney exchange transplantation: Maximizing the donor pool.

In the last decade, paired kidney exchange (PKE) transplantation has gained popularity worldwide as a viable alternative for end stage renal disease (ESRD) patients who have incompatible or sensitized donors. This study presents our experience with PKE transplantation and compares outcome between PKE and non-PKE renal transplant recipients. Between February 2010 and November 2013, 742 transplants were performed, of which 26 (3.5%) were PKE transplantations. All were two-way exchanges. PKE recipients were significantly older than non-PKE (46.73 ± 9.71 vs. 40.08 ± 13.36 years; P = 0.012) while donor ages were comparable. PKE patients had significantly higher number of HLA mismatches (5.03 ± 1.14 vs. 3.49 ± 1.57; P < 0.0001). After a median follow-up of 20 months (range: 3-47 months), there was no significant difference in patient survival (PKE 96.16% vs. non-PKE 96.65%; P = 0.596) and death censored graft survival (PKE 96.16% vs. non-PKE 96.37%; P = 1). Mean serum creatinine at 1 month and at last follow-up was lower in PKE versus non-PKE group (0.98 ± 0.33 vs. 1.3 ± 0.61 mg/dl; P = 0.008 and 0.96 ± 0.30 vs. 1.27 ± 0.57 mg/dl, P = 0.006, respectively). Biopsy proven acute rejection rate was 11.5% in PKE group and 16.89% in non-PKE patients (P = 0.6). To conclude, paired kidney donation is an excellent way of increasing the donor pool and needs to be promoted to overcome the shortage of suitable kidney in our country.

Invasive gastric mucormycosis and cytomegalovirus infection in an ABO incompatible renal transplant recipient.

Opportunistic infections are common in immunocompromised patients, such as solid organ transplant recipients. Both fungal and viral infections in posttransplant period increase morbidity and mortality. Cytomegalovirus (CMV) remains one of the most important pathogens. CMV disease may manifest as a nonspecific febrile syndrome or tissue-invasive infections. Zygomycosis is a rare infection, usually presents in rhino-cerebral, pulmonary and disseminated forms; gastrointestinal (GI) tract being a rare site of involvement. Newer techniques for early diagnosis and efficient therapies are essential for a better outcome of the disease; however, mortality rate remains high despite aggressive therapy. We report a renal transplant recipient, who developed gastric mucormycosis along with tissue invasive CMV disease, within 4 weeks of renal transplant and was diagnosed on the basis of upper GI endoscopy and gastric biopsy. The patient succumbed to the infection in spite of gastrectomy, antifungal and antiviral therapy.

Early corticosteroid withdrawal regimen in a living donor kidney transplantation program.

Steroids have been the essential component of transplant immunosuppression. Recently, with availability of better immunosuppressive agents, many centers have started steroid free transplant with good success rates. We analyzed the outcomes of early corticosteroid withdrawal (CSW) protocol in our living donor kidney transplant programme. We included 73 patients on CSW protocol on basiliximab + tacrolimus and mycophenolate mofetil and compared them with 67 recipients on similar regimen with corticosteroids (CSs). CSW group received prednisolone 40 mg on day 1, which was stopped on day 5. Outcomes were evaluated in terms of acute rejection (AR), infections, new onset diabetes after transplant (NODAT), renal function and graft or patient loss. In CSW group, 15/73 (20.5%) patients developed AR, when compared to 5/67 (7.5%) in CS group, (P = 0.02). Biopsy proven acute rejection was seen in 12/72 (16.6%) in CSW group and 5/67 (7.5%) in CS (P = 0.1). One patient in CSW group developed antibody mediated rejection. NODAT was similar (9% in CS vs. 3.7% in CSW, P = 0.09), but infections were higher in CSW group (20.5% vs. 7.5%, P = 0.02). Mean serum creatinine was similar at 6 months (1.24 ± 0.6 in CS and 1.25 ± 0.3 in CSW, P = 0.9). Graft survival was 100% and 97% (P = 0.1) and patient survival was 98.6% and 98.5% (P = 0.9) in CSW and CS groups. Early corticosteroid withdrawal with basiliximab induction was associated with increased risk of AR but did not have any effect on short term graft and pateint survival.

Muscle response during treatment of Class II Division 1 malocclusion with Forsus Fatigue Resistant Device.

PURPOSE: To evaluate the muscle response in order to determine the mechanism of neuromuscular adaptations with Forsus Fatigue Resistant Device which has greater elasticity and flexibility; allows greater range of movement of mandible; is available in prefabricated assembly of springs, tubes and rods and is a simple, effective and reliable corrective appliance that benefits not only growing patients but also malocclusions that previously required extractions, headgears and surgery. METHOD: Bilateral EMG activity from anterior temporalis and masseter muscles was monitored longitudinally on 10 young growing females with Class II Division 1 malocclusion to determine changes in postural, swallowing, and maximal voluntary clenching over an observation period of 6 months. RESULTS: There was a significant decrease in the muscle activity at one month after Forsus Fatigue Resistant Device insertion during swallowing of saliva and maximal voluntary clenching which gradually returned to pre treatment levels at the end of six months. CONCLUSION: This study suggests that Forsus Fatigue Resistant Device should be given for at least six months to allow for adequate neuromuscular adaptations to occur for long-term stability of the result.

Evidence-based medicine in practice.

Evidence-based medicine (EBM) has emerged as a dominant paradigm in healthcare, strongly influencing clinical decision-making, access to and funding for interventions. However, EBM has a number of limitations, which appear to have been under-represented in the literature. We explore the development and shortcomings of EBM, and consider a complementary role for practice-based evidence in guiding clinical decision-making. EBM is a valuable and important part of the medical landscape. However, a range of significant limitations makes over-reliance on this paradigm problematic. Appropriate recognition of practice-based evidence helps to bridge the gap between evidence and clinical practices.

The distribution of individual tooth impaction in general dental patients of Northern India.

OBJECTIVE: To investigate the distribution of individual tooth impaction in general dental patients of Northern India. SETTING: Centre for Dental Education and Research, All India Institute of Medical Sciences, New Delhi. DESIGN: Hospital based crossectional study. METHODS: General dental patients were examined clinically and impacted teeth were diagnosed from radiographs. The distribution of impacted teeth (excluding third molars) with respect to the arch, side and gender were recorded. The results were analyzed with respect to the prevalence of individual tooth impaction. The distribution of teeth impaction was evaluated by using the Chi-square test. A p-value of < 0.05 was considered as statistically significant. RESULTS: Of 27,529 general dental patients examined, 134 (0.49%) had at least one-impacted tooth and a total of 220 impacted teeth were recorded. The most frequently impacted teeth were maxillary canines (52.27%) and the least frequently impacted teeth were maxillary first and second molars (0%). CONCLUSIONS: The prevalence of teeth impaction in the North Indian dental patients was less when compared with the other populations. The most frequently impacted teeth were maxillary canines and the least frequently impacted teeth were maxillary first and second molars.

Temporomandibular joint adaptations following two-phase therapy: an MRI study.

AIM: To document the alterations within the condyle-glenoid fossa (C-GF) complex and the positional changes of the glenoid fossa in the cranium after removable functional appliance therapy and after the completion of fixed appliance therapy. SETTING AND SAMPLE: The Department of Orthodontics, Centre for Dental Education and Research, All India Institute of Medical Sciences, New Delhi, India. The study sample consisted of 12 growing children (eight girls and four boys) between 10 and 14 years of age with skeletal Class II division 1 malocclusion selected on well defined criteria. MATERIALS AND METHODS: All patients were treated with either the Twin Block or the Bionator appliance followed by fixed appliances. Mean total treatment duration was 28 months. The changes in and around the C-GF complex were evaluated using MRI at pre-treatment stage, after functional appliance therapy and at the completion of fixed mechanotherapy. RESULTS: Forward condylar position within the glenoid fossa and articular disc retrusion with respect to the condylar head were statistically significant after functional appliance therapy. However, the condyles had a relatively concentric position within the glenoid fossa, while the articular disc resumed its pre-treatment position at the end of the treatment. Linear measurements from the centre of the external auditory meatus to the post-glenoid spine revealed a 1.3-mm forward relocation of the post-glenoid spine along the Frankfurt Horizontal plane. CONCLUSIONS: Forward relocation of the C-GF complex seems to be one of the mechanisms of action of functional appliances, while the internal anatomic arrangement within the temporomandibular joint (TMJ) complex normalizes to its pre-treatment position.

Staff recruitment, development and global mobility.

This paper considers issues that relate to staff recruitment, staff development and global mobility of dental academics. Published literature, which has a North American bias, is reviewed. Recommendations, which may be applicable world-wide, are made to address evident and pertinent areas of concern in terms of the availability of quality dental teaching staff in dental teaching institutions so as to sustain the global dental academic enterprise at appropriately high levels of achievement.

Alkaline phosphatase activity in gingival crevicular fluid during canine retraction.

OBJECTIVES: The aim of the study was to investigate alkaline phosphatase activity in the gingival crevicular fluid (GCF) during orthodontic tooth movement in humans. SETTING AND SAMPLE POPULATION: Postgraduate orthodontic clinic. Ten female patients requiring all first premolar extractions were selected and treated with standard edgewise mechanotherapy. EXPERIMENTAL VARIABLE: Canine retraction was done using 100 g sentalloy springs. Maxillary canine on one side acted as experimental site while the contralateral canine acted as control. OUTCOME MEASURE: Gingival crevicular fluid was collected from mesial and distal of canines before initiation of canine retraction (baseline), immediately after initiation of retraction, and on 1st, 7th, 14th and 21st day and the alkaline phosphatase activity was estimated. RESULTS: The results show significant (p < 0.05) changes in alkaline phosphatase activity on the 7th, 14th and 21st day on both mesial and distal aspects of the compared experimental and control sides. The peak in enzyme activity occurred on the 14th day of initiation of retraction followed by a significant fall in activity especially on the mesial aspect. CONCLUSIONS: The study showed that alkaline phosphatase activity could be successfully estimated in the GCF using calorimetric estimation assay kits. The enzyme activity showed variation according to the amount of tooth movement.

Restoration of traumatized anterior teeth by interdisciplinary approach: report of three cases.

These cases had been discussed having massive coronal fracture, rotation and intrusion of teeth. In case one, both the central incisors, i.e. 11 and 21 were fractured only one-third of tooth material was remaining. In case two, 21 was fractured and intruded. In case three, 12 and 21 were avulsed and 11 was rotated and intruded. These cases were successfully treated by multidisciplinary approach. Fractured crown with periapical pathology were endodontically treated and then rotated and intruded teeth were repositioned by removable or fixed orthodontic appliance. Subsequent to endodontic and orthodontic treatment prosthodontic rehabilitation was done.

Non-syndromic multiple supernumerary teeth transmitted as an autosomal dominant trait.

Supernumerary teeth are common in the general population and occur more frequently in-patients with family history of such teeth. Multiple supernumerary teeth are associated with cleidocranial dyplasia and Gardner syndrome. However it is rare to find multiple supernumeraries in individuals with no other associated disease or syndrome. We describe the occurrence of multiple supernumerary teeth in a family occurring as a non-syndromal trait. The autosomal dominant transmission of non-syndromal multiple supernumerary teeth is new.

Class-III malocclusion: genetics or environment? A twins study.

Etiology of class-III malocclusion is generally believed to be genetic. A wide range of environmental factors have been suggested as contributing factors for the development of class-III malocclusion. Twin study is one of the most effective methods available for investigating genetically determined variables of malocclusion. Discordancy for class-III malocclusion is a frequent finding in dizygotic twins. However, class-III malocclusion discordancy in monozygotic twins is a rare finding. The purpose of this study of monozygotic twins is to assess the genetic and environmental components of variation within the cranio-dento-facial complex.

"Craniofacial and dental manifestations of a case of Proteus syndrome".

Proteus syndrome, which is a reference to the ancient Greek god Proteus, the Polymorphous, was called to the attention of pediatricians. Recognition of this syndrome has been difficult because of the variability of the syndrome's manifestations and because of its rarity. We describe a rare case of Proteus syndrome and we discuss its differential diagnosis. Our case presents with hemi facial hypertrophy, scrotal tongue, enamel hyperplasia as well as differential in the size of the dentition on both sides of the arch.

Secondary bone grafting in cleft lip and palate with eruption of tooth into the graft: a case report.

Secondary bone grafting in cleft lip and palate patients is performed preferably before the eruption of permanent canine in order to provide adequate periodontal support for eruption and preservation of the teeth adjacent to the cleft. Presented here with is a case of unilateral cleft lip and palate, which was followed up from birth to 15 years of age. The role of an orthodontist in the team approach for management of such anomalies is described. Also discussed in detail is the entire range of treatment procedures the child underwent, especially the role of secondary bone grafting.

EEC syndrome--a case report.

EEC syndrome is a multiple congenital anomaly syndrome characterized by ectodermal dysplasia, distal limb anomaly, cleft lip and palate and ocular adnexia anomalies. A case report of a 10 year old female patient with EEC is presented and it is emphasised that management of these cases requires a multidisciplinary approach. Early diagnosis will allow parents to get accurate counseling and in particular obtain reassurance regarding the low risk of mental handicap.
