A Descriptive Study on Imperiled Cochlear Implant Salvage Using Double Flap Cover-What We Learned in 6 Years.

Cochlear implant surgery is the standard of care for severe sensorineural hearing loss. Infection followed by implant extrusion is an infrequent complication of this surgery. The ideal treatment is explantation of the implant. However, implant removal and reimplantation is a challenging surgery and may have poor speech reception outcomes. The cost of a new implant especially in developing countries is also a deterrent. Our study dwells on the feasibility of salvaging exposed cochlear implants by a combination of pericranial flaps followed by a scalp flap cover. The study was done in a tertiary care hospital over a period of six years. Out of 303 cochlear implant surgeries, 12 patients had implant exposure and extrusion. Patients having meningitis and sepsis were excluded from the study. All patients underwent debridement and cover with double flap (Pericranial flaps and scalp rotation flap). The average operating time was 2.17 h. The surgery is technically simple with a short learning curve. It brings in rich blood supply and there is fair amount of tissue mobility. In 11 patients we were able to salvage the implant. Patients were followed for a period of 01 year post operatively. Our study suggests that salvage of infected implant should be attempted as it is feasible, durable and effective in appropriate patients.

Evidence-Based Guidelines for the Management of Allergic Bronchopulmonary Aspergillosis (ABPA) in Children and Adolescents with Asthma.

BACKGROUND: Allergic bronchopulmonary aspergillosis (ABPA) frequently complicates asthma. There is urgent need to develop evidence-based guidelines for the management of ABPA in children. The Evidence Based Guideline Development Group (EBGDG) of the Indian Academy of Pediatrics (IAP) National Respiratory Chapter (NRC) addressed this need. METHODS: The EBGDG shortlisted clinical questions relevant to the management of ABPA in asthma. For each question, the EBGDG undertook a systematic, step-wise evidence search for existing guidelines, followed by systematic reviews, followed by primary research studies. The evidence was collated, critically appraised, and synthesized. The EBGDG worked through the Evidence to Decision (EtD) framework, to formulate recommendations, using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. RESULTS: Seven clinical questions were prioritized, and the following recommendations formulated. (1) Children with poorly controlled asthma should be investigated for ABPA (conditional recommendation, moderate certainty of evidence). (2) Low dose steroid therapy regimen (0.5 mg/kg/d for the first 2 wk, followed by a progressive tapering) is preferable to higher dose regimens (conditional recommendation, very low certainty of evidence). (3) Oral steroid regimens longer than 16 wk (including tapering), should not be used (conditional recommendation, very low certainty of evidence). (4) Antifungals may or may not be added to steroid therapy as the evidence was neither in favour nor against (conditional recommendation, low certainty of evidence). (5) For clinicians using antifungal agents, the EBGDG recommends against using voriconazole instead of itraconazole (conditional recommendation, very low certainty of evidence). (6) No evidence-based recommendation could be framed for using pulse steroid therapy in preference to conventional steroid therapy. (7) Immunotherapy with biologicals including omalizumab or dupilumab is not recommended (conditional recommendation, very low certainty of evidence). CONCLUSIONS: This evidence-based guideline can be used by healthcare providers in diverse clinical settings.

Settling moths are the vital component of pollination in Himalayan ecosystem of North-East India, pollen transfer network approach revealed.

Majority of the pollination related studies are based on the diurnal pollinators, and the nocturnal pollinators received less scientific attention. We reveal the significance of settling moths in pollination of angiosperm families in Himalayan ecosystem of North-East India. The refined and novel method of pollen extraction from the proboscides provides a more robust assessment of the pollen carrying capacity. The study is based on one of the largest data sets (140 pollen transporter moth species (PTMS)), with interpretation based on seasonal as well as altitudinal data. In the present study about 65% moths (91 species) carried sufficient quantities of pollen grains to be considered as potential pollinators (PPMS). Teliphasa sp. (Crambidae) and Cuculia sp. (Noctuidae) are found to carry the highest quantity of pollen. We found pollen grains of 21 plant families and the abundant pollen are from Betulaceae, Fabaceae, Rosaceae and Ericaceae. Species composition of PTMS and PPMS in pre-monsoon, monsoon, and post-monsoon revealed the dominance of Geometridae. Maximum diversity of PTMS and PPMS is found from 2000 to 2500 m altitude. The nocturnal pollen transfer network matrices exhibited high degree of selectivity (H2' = 0.86).

Role of Lactobacillus reuteri DSM 17938 on Crying Time Reduction in Infantile Colic and Its Impact on Maternal Depression: A Real-Life Clinic-Based Study.

BACKGROUND: Infantile colic is characterized by prolonged periods of inconsolable, incessant crying and persistent fussing in an otherwise healthy infant. It is a self-limiting condition, but causes significant stress to mothers. AIM: To observe the role of Lactobacillus reuteriDSM 17938 in reducing crying time in colicky infants in routine clinical practice. METHODS: This was a prospective observational multicentric clinic-based study. Each practitioner included approximately 30 infants < 5 months of age with infantile colic who were prescribed L. reuteri DSM 17938 for a period of 21 days. There were four physical consultations and two telephonic consultations. The parents were given a daily diary to record the duration of crying and fussing episodes and a questionnaire was administered during the consultations. RESULTS: A total of 120 infants with a mean age of 56.9 ± 34.2 days were included in this 28-day study. The mean crying time as reported by the parents in the subject diary reduced from 248.2 ± 101.2 min, 95% CI: 229.45, 266.94 at baseline to 45.6 ± 79.1 min 95% CI: 31.02, 60.31 at study end (P < 0.01). The clinical response (defined as reduction of 50% in crying time) was observed in 85% of subjects at study end. The fussiness and parental perception of colic recorded during the consultations were reduced by 66% and 72%, respectively, at study end. The maternal depression scores were reduced to 63% at study end. CONCLUSION: L. reuteri DSM 17938 was associated with a significant reduction in crying time in colicky infants, and showed improvement in maternal depression.

Salvage of Infected Cardiac Implantable Electrical Devices with Subpectoral Plane Pocket Revision.

Introduction Infection of cardiac implantable electrical devices (CIEDs) may lead to serious complications. Complete CIED explantation is expensive, requires expertise, not free from complications, and may not be an option in patients with device dependence. Aim To highlight that carefully selected infected CIEDs can be salvaged by placing the device in a subpectoral pocket below the pectoralis major muscle. We conducted a retrospective descriptive observational study. Material and Methods Twelve patients (10 male and two female) with erosion, exposure or infection of infraclavicular, subcutaneously placed CIED were treated over a 30-month period between July 2018 and December 2020. The technique involved debridement and excision of a peridevice capsule, creating a subpectoral pocket beneath the pectoralis major muscle, and placing the CIED in a new pocket with total muscle coverage and closure of skin without tension. Results Twelve patients ( m = 10; f = 2) with a mean age of 65 years (range, 46-82 years) presented with infection of CIED within 9 months of implantation. None had sepsis or endocarditis. In nine patients, CIEDs were successfully salvaged with relocation to subpectoral pocket. Mean follow-up was 20 months (range, 8-30 months). Three out of 12 developed reinfection that ultimately required CIED explantation. There was no mortality. Conclusion In the absence of sepsis or endocarditis, infected CIEDs may be attempted at salvage by subpectoral pocket placement. This obviates the need for potentially risky explantation or replacement of expensive CIEDs.

Indian Academy of Pediatrics (IAP) Advisory Committee on Vaccines and Immunization Practices (ACVIP) Recommended Immunization Schedule (2018-19) and Update on Immunization for Children Aged 0 Through 18 Years.

JUSTIFICATION: There is a need to revise/review recommendations regarding existing vaccines in view of current developments in vaccinology. PROCESS: Advisory Committee on Vaccines and Immunization Practices (ACVIP) of Indian Academy of Pediatrics (IAP) reviewed the new evidence, had two meetings, and representatives of few vaccine manufacturers also presented their data. The recommendations were finalized unanimously. OBJECTIVES: To revise and review the IAP recommendations for 2018-19 and issue recommendations on existing and certain new vaccines. RECOMMENDATIONS: The major changes in the IAP 2018-19 Immunization Timetable include administration of hepatitis B vaccine within 24 hours of age, acceptance of four doses of hepatitis B vaccine if a combination pentavalent or hexavalent vaccine is used, administration of DTwP or DTaP in the primary series, and complete replacement of oral polio vaccine (OPV) by injectable polio vaccine (IPV) as early as possible. In case IPV is not available or feasible, the child should be offered three doses of bivalent OPV. In such cases, the child should be advised to receive two fractional doses of IPV at a Government facility at 6 and 14 weeks or at least one dose of intramuscular IPV, either standalone or as a combination, at 14 weeks. The first dose of monovalent Rotavirus vaccine (RV1) can be administered at 6 weeks and the second at 10 weeks of age in a two-dose schedule. Any of the available rotavirus vaccine may be administered. Inactivated influenza vaccine (either trivalent or quadrivalent) is recommended annually to all children between 6 months to 5 years of age. Measles-containing vaccine (MMR/MR) should be administered after 9 months of age. Additional dose of MR vaccine may be administered during MR campaign for children 9 months to 15 years, irrespective of previous vaccination status. Single dose of Typhoid conjugate vaccine (TCV) is recommended from the age of 6 months and beyond, and can be administered with MMR vaccine if administered at 9 months. Four-dose schedule of anti-rabies vaccine for Post Exposure Prophylaxis as recommended by World Health Organization in 2018, is endorsed, and monoclonal rabies antibody can be administered as an alternative to Rabies immunoglobulin for post-exposure prophylaxis.

A new paradigm in facial reanimation for long-standing palsies?

BACKGROUND: A chance observation of return of excellent facial movement, after 18 months following the first stage of cross-face nerve grafting, without free functional muscle transfer, in a case of long-standing facial palsy, lead the senior author (RBA) to further investigate clinically. PATIENTS AND METHODS: This procedure, now christened as cross-face nerve extension and neurotization, was carried out in 12 patients of very long-standing facial palsy (mean 21 years) in years 1996-2011. The mean patient age and duration of palsy were 30.58 years and 21.08 years, respectively. In patients, 1-5 a single buccal or zygomatic branch served as a donor nerve, but subsequently, we used two donor nerves. The mean follow-up period was 20.75 months. RESULTS: Successive patients had excellent to good return of facial expression with two fair results. Besides improved smile, patients could largely retain air in the mouth without any escape and had improved mastication. No complications were encountered except synkinesis in 1 patient. No additional surgical procedures were performed. CONCLUSION: There is experimental evidence to suggest that neurotization of a completely denervated muscle can occur by the formation of new ectopic motor end plates. Long-standing denervated muscle fibres eventually atrophy severely but are capable of re-innervation and regeneration, as validated by electron microscopic studies. In spite of several suggestions in the literature to clinically validate functional recovery by direct neurotization, the concept remains anecdotal. Our results substantiate this procedure, and it has the potential to simplify reanimation in longstanding facial palsy. Our work now needs validation by other investigators in the field of restoring facial animation.

Reactogenicity and safety of the human rotavirus vaccine, Rotarix™ in The Philippines, Sri Lanka, and India: a post-marketing surveillance study.

Regulatory bodies in The Philippines, Sri Lanka, and India require post-marketing surveillance to provide additional safety data on Rotarix™ in real-life settings. In such studies conducted in The Philippines (November 2006 to July 2012; NCT00353366), Sri Lanka (November 2008 to August 2009; NCT00779779), and India (August 2009 to April 2010; NCT00938327), 2 doses of Rotarix™ were administered according to the local prescribing information (PI). The occurrence of at least Grade "2"/"3" solicited adverse event (AE) (fever, vomiting, or diarrhea), within 15 days in The Philippines or 8 days in Sri Lanka and India; unsolicited AEs within 31 days and serious adverse events (SAEs) throughout the study were recorded. Of the 1494, 522, and 332 infants enrolled in The Philippines, Sri Lanka, and India, 14.7% 14.9% and 12.7% infants, respectively recorded at least Grade "2"/"3" solicited AEs. The most commonly reported solicited AEs were irritability in The Philippines (32.2% post-Dose-1; 23.5% post-Dose-2) and India (23.0% post-Dose-1; 13.2% post-Dose-2), and fever (18.0% post-Dose-1; 20.2% post-Dose-2) in Sri Lanka. Unsolicited AEs were recorded in 24.5% (The Philippines), 4.8% (Sri Lanka), and 6.9% (India) of infants. Forty-one SAEs were recorded in the Philippines of which 6 (decreased oral intake with increased sleeping time and constipation; pneumonia, urinary tract infection, and intussusception) were considered by the investigators as causally related to vaccination. One vaccine-unrelated SAE occurred in a Sri Lankan infant. All SAEs resolved and the infants recovered. Two doses of Rotarix™, administered to healthy infants according to local PI, were well tolerated in The Philippines, Sri Lanka, and India.

A novel route for placing free flap pedicle from a palatal defect.

One of the better options available to repair a large palatal defect is by employing a free flap. Almost all the times such free flaps are plumbed to facial vessels. The greatest challenge in such cases is the placement of the pedicle from palatal shelf to recipient vessels because there is no direct route available. As majority of large palatal fistulae are encountered in operated cleft palates there is a possibility of routing the pedicle through a cleft in the maxillary arch or via pyriform aperture. When such a possibility doesn't exist the pedicle is routed behind the maxillary arch. We describe a novel technique of pedicle placement through a maxillary antrostomy, in this case report, where a large palatal fistula in a 16 year old boy was repaired employing a free radial artery forearm flap. The direct route provided by maxillary antrostomy is considered the most expeditious of all possibilities mentioned above.

Total upper eyelid reconstruction by single staged malar-cheek flap.

We report a case of total upper eyelid reconstruction by a new technique after excision of an eyelid tumour. The eyelid was reconstructed by a horizontal, laterally based flap from just under the lower eyelid combined with a chondro-mucosal graft from the nasal septum. Surgical outcome was an excellent aesthetically reconstructed eyelid, which was mobile and properly gliding on the globe to achieve complete eye closure.

Comparative efficacy of intralesional verapamil hydrochloride and triamcinolone acetonide in hypertrophic scars and keloids.

There is not much level 1 evidence based literature to guide management of hypertrophic scars and keloids despite an array of therapeutic modalities at disposal. Intralesional (i/l) triamcinolone injections have remained a gold standard in non surgical management. Sporadic reports on use of i/l verapamil suggest its efficacy. Since verapamil has not found sufficient mention as an effective alternative modality, it was decided to undertake a randomized study which could also address some additional clinical parameters. A randomized, parallel group and observer blinded comparison with 40 patients (48 scars) was carried out to compare the effects of i/l triamcinolone (T) (22 scars) and verapamil injections (V) (26 scars). 1.5 ml was the maximum indicative volume decided in the study protocol for both the drugs (triamcinolone @40 mg/ml and verapamil @ 2.5 mg/ml). Patients included were aged between 15-60 years with scars ranging between 0.5-5 cm (but total area roughly <6 cm(2)), and scars under 2 years duration. Patients with keloidal diathesis were excluded. Injections were scheduled every three weeks until complete flattening of the scar or eight sessions, which ever came earlier. No concomitant therapies like massage, silicone gel or pressure garments were used. Scar evaluation at each stage was done by serial photographic records as well as by Vancouver Scar Scale (VSS). Comparative survival analysis between the two drugs was done using Kaplan Meier curves, and VSS scores were analyzed using Wilcoxon test and log rank test. Mean zero VSS scores were achieved with treatments in respect of scar height (T-12 weeks, V-21 weeks), vascularity (T-15 weeks, V-18 weeks) and pliability (T-15 weeks, V-21 weeks). The improvement in scar vascularity and pliability kept pace with decrease in scar height, in both the groups. There was not much difference in the rate of change of scar pigmentation with either drug but almost 60% patients in both the groups regained normal pigmentation. Our study adds to evidence of verapamil's capability in flattening the raised scars. With an extremely low cost and fewer adverse effects it deserves better positioning in the wide armamentarium against hypertrophic scars. It also offers several therapeutic possibilities to alternate with triamcinolone or be used simultaneously in larger (or multiple) scars.

Securing aesthetic outcomes for composite grafts to alar margin and columellar defects: A long term experience.

INTRODUCTION: Composite grafts for nasal reconstruction have been around for over a century but the opinion on its virtues and failings keeps vacillating with a huge difference on the safe size of the graft for transfer. Alar margin and columellar defects are more distinct than dorsal nasal defects in greater difficulty in ensuring a good aesthetic outcome. We report our series of 19 consecutive patients in whom a composite graft was used to reconstruct a defect of alar margin (8 patients), alar base (7 patients) or columella (4 patients). PATIENTS AND METHODS: Patient ages ranged from 3-35 years with 5 males and 14 females. The grafts to alar margin and base ranged 0.6-1 cm in width, while grafts to columella were 0.7-1.2 cm. The maximum dimension of the graft in this series was 0.9 mm x 10 mm. Composite grafts were sculpted to be two layered (skin + cartilage), three layered wedges (skin + cartilage + skin) or their combination (two layered in a portion and three layered in another portion). All grafts were cooled in postoperative period for three days by applying an indigenous ice pack of surgical glove. The follow up ranged from 3-9 months with an average of 4.5 months. RESULTS: All of our 19 composite grafts survived completely but they all shrank by a small percentage of their bulk. Eleven patients rated the outcome between 90-95% improvement. We noticed that composite grafts tended to show varied pigmentation in our patients, akin to split skin grafts. CONCLUSION: In our opinion, most critical to graft survival is its size and the ratio of the marginal raw area to the graft bulk. We recommend that graft width should not exceed 1 cm to ensure complete survival even though larger sized grafts have been reported to survive. We recommend cooling of the graft and justify it on the analogy of 'warm ischemia time' for a replantation, especially in warmer climes like ours in India. We have outlined several considerations in the technique, with an analysis of differing opinions that should facilitate a surgeon in making an informed choice.
