Bilateral Apogeotropic Lateral Canal BPPV: Role of Secondary Signs of Lateralization in Diagnosis.

Bilateral lateral canal benign paroxysmal positional vertigo (BPPV) is extremely uncommon because of difficulties in diagnosing such cases. We present first case of bilateral apogeotropic lateral canal BPPV. We want to stress that secondary signs of lateralization like bow lean test is of great help in diagnosing such cases.

Polymorphisms in the HSF2, LRRC6, MEIG1 and PTIP genes correlate with sperm motility in idiopathic infertility.

The aim of this study was to investigate the association of 24 functionally important single nucleotide polymorphisms (SNPs) with male infertility. In this cross-sectional study, we genotyped 24 functionally important single nucleotide polymorphisms in 24 infertility candidate genes in 500 oligo-/astheno-/oligoastheno-/normo-zoospermic infertile men with idiopathic infertility. Sequenom iPlex gold assay was used for genotyping. Sperm count and motility were compared between prevalent genotypes at each test locus. We did not observe any significant difference in the average sperm count between the alternate genotypes for the loci in the KLK3, LRRC6, MEIG1, HSF2, ESR2 and PTIP genes. However, we observed a significant difference in sperm motility between the alternate genotypes for the loci in the LRRC6, MEIG1, HSF2 and PTIP genes. Polymorphisms in the LRRC6 (rs200321595), MEIG1 (rs150031795), HSF2 (rs143986686) and PTIP (rs61752013) genes show association with sperm motility.

Usefulness of high definition sialoendoscope for evaluation of lacrimal drainage system in congenital nasolacrimal duct obstruction.

PURPOSE: Sialoendoscope was used as a dacryoendoscope, high- definition images of the lacrimal drainage system (LDS) were captured and its performance in congenital nasolacrimal duct obstruction (CNLDO) is reported. METHODS: Nasal endoscopy was done as the first in all the cases using a 0°, 2.7 mm nasal endoscope (Karl Stroz Tutlingan Germany). This was followed by Dacryoendoscopy (DEN) of the lacrimal drainage system from puncta till the valve of Hasner. DEN was performed under general anaesthesia in 26 children (including 17 primary and 9 failed probing cases). All cases were examined using 0.8 mm sialoendoscope (Karl Storz, Tuttlingen, Germany) with fibreoptic light transmission with a side port for irrigation. RESULTS: We were able to obtain high-definition images of canaliculi, lacrimal sac, sac duct junction, proximal, mid and distal segments of nasolacrimal duct in all the children with CNLDO.In 17 primary cases 16 had distal membranous obstruction and I case had proximal canalicular obstruction. In nine children with history of failed probing, five had membranous obstruction, two had dacryoliths, two had NLD malformation at different levels. An overall success rate of 88.4% was achieved. CONCLUSION: Sialoendoscope can be used as high-definition dacryoendoscope for diagnostic and therapeutic use in CNLDO. Useful information can be obtained on dacryoendoscopy in complex CNLDO cases.

Incidence of postoperative pain after single-visit and multiple-visit root canal therapy: A randomized controlled trial.

Background: Short-term complications after root canal therapy (RCT) include mild pain or flare-up. Patients regard these complications as a benchmark for the assessment of clinician's abilities. In this context, the evidence for recommending either one- or two-visit RCT is not consistent. Aims: This study aims to compare the prevalence of postoperative pain and tenderness to percussion after single-visit (SV) versus two-visit RCT on the mandibular first molar. Materials and Methods: The study was registered with www.ctri.nic.in (CTRI/2019/05/019067). Seventy individuals requiring RCT on a mandibular first molar were selected and randomly ascribed to either single- (Group 1, n = 35) or two-visit RCT (Group 2, n = 35). Postoperative pain levels were assessed using heft parker visual analog scale. The treated teeth were appraised for tenderness to percussion after 1 week of obturation. Statistical Analysis: Thirty-four patients were evaluated in each group: One patient, each, dropped out from both the groups. The data analysis was done using Student's t-test and Chi-square test. Results and Conclusion: Pain score in multiple-visit (MV) was significantly higher than SV after 12- (P = 0.039) and 48 h (P = 0.043). Short-term postoperative pain was higher in MV than SV RCT of mandibular first molar teeth.

A rare association of blepharophimosis-ptosis-epicanthus inversus case with congenital nasolacrimal duct obstruction.

PURPOSE: The aim of reporting this case is to describe a rare combination of blepharophimosis-ptosis-epicanthus inversus syndrome with congenital nasolacrimal duct obstruction. A variety of lacrimal anomalies have been seen in blepharophimosis-ptosis-epicanthus inversus syndrome but the occurrence of nasolacrimal duct obstruction is rare. METHOD: The blepharophimosis-ptosis-epicanthus inversus syndrome is an autosomal dominant rare genetic defect with clinical manifestation of dysplasia of the eyelids, palpebral fissures, flat nasal bridge, and ptosis. A 20-month-old boy was referred with the complaints of watering and discharge from his right eyes since birth. On examination, the child had all the features of blepharophimosis-ptosis-epicanthus inversus syndrome with right congenital nasolacrimal duct obstruction in line with the published reports. RESULT: On endoscopic probing and irrigation, the probe could not be visualized into the inferior meatus. On dacryoendoscopy, the membranous part of the nasolacrimal duct was found to be completely obliterated with no light transmission into the nose indicating a malformed nasolacrimal duct. The child was managed by endoscopic dacryocystorhinostomy. We could find only one case report published so far on the combination of congenital nasolacrimal duct obstruction with blepharophimosis-ptosis-epicanthus inversus syndrome. This study adds one more case of blepharophimosis-ptosis-epicanthus inversus syndrome with congenital nasolacrimal duct obstruction and adjuvant use of dacryoendoscopy.

Comprehensive Community Screening of Otological Patients by Trained Technicians Using a Telemedicine Device: An Efficient and Cost-Effective Way to Triage Patients With Ear Diseases.

OBJECTIVE: To emphasize the benefits of tele-otology in community screening of patients with ear diseases. METHODS: A retrospective study of all patients screened and treated under the Shruti tele-otology program between 2013 and 2019 was conducted. It involved screening, diagnosis, medical management, surgical intervention, and rehabilitation using hearing aid. The study focused on underprivileged and underserved community of rural and urban slums across 12 states of India. The study was conducted using a telemedicine device called ENTraview, that is, a camera-enabled android phone integrated with an otoscope and audiometry screening. RESULT: A total of 810 746 people were screened, and incidence of various ear diseases was recorded. Ear problems were found in 265 615 (33%) patients, of which 151 067 (57%) had impacted wax, 46 792(18%) had chronic suppurative otitis media, 27 875 (10%) had diminished hearing, 12 729 (5%) had acute otitis media and acute suppurative otitis media (ASOM), and 27 152 (10%) had problems of foreign body, otomycosis, and so on. Of the total 265 615 referred patients, 20 986 (8%) reported for treatment and received treatment at a significantly reduced cost through Shruti program partners. The conversion rate of nonsurgical and surgical procedure was also compared, and it was found that, while 9% of the patients opted for nonsurgical treatment, only 3% opted for surgery in the intervention group giving a significant P value of .00001. CONCLUSION: The potential for telemedicine to reduce inequalities in health care is immense but remains underutilized. Shruti has largely been able to bridge this gap as it is an innovative, fast, and effective programs that address the ear ailment in the community.

Community Triage of Otology Patients Using a Store-and-Forward Telemedicine Device: A Feasibility Study.

Chronic otitis media is a major contributor to acquired hearing loss in developing countries. Developing countries such as India, with huge populations and poor health infrastructures, have always felt the shortage of trained specialists who can provide quality care to meet the enormous demand for treatment of this disease. This pilot study assessed the feasibility of empowering trained health workers equipped with ENTraview, a store-and-forward telemedicine device that integrates a camera- enabled smart phone with an otoscope. This device allows the screening of otology patients within the community. Three months of extensive training was provided to five community health workers on primary ear and hearing care, including training on the use of the ENTraview device. Community otology screenings were conducted to triage otology patients and provide them with specialized ENT care at a tertiary hospital. In the initial 6 months of the project, 45 screening camps were organized, which screened 3,000 patients free of cost. Of these 3,000 screened patients, 54% (1,619) were referred for ENT consultation and 215 patients reported. Nearly 50% (103) of the 215 reporting patients required surgical intervention, and 29 patients underwent surgery. Reaching out to the community by remote screening of ear diseases by trained technicians with a telemedicine device seems to be an effective and cost-effective way to triage patients with otologic pathologies.

Role of dacryoendoscopy in refractory cases of congenital nasolacrimal duct obstruction.

Purpose: To highlight the importance of dacryoendoscopy in recognizing the factors responsible for failure with successful recanalization obviating the need for dacryocystorhinostomy in a few selective cases.Method: A retrospective study of 13 children undergoing dacryoendoscopy for refractory congenital nasolacrimal duct obstruction (CNLDO) was carried out during a period of 3 years from 2016 to 2018. Children with single or multiple failed probings were included in the study.Results: Out of the total 13 cases included in the study there 9 males and 4 females. The age ranged from 9 months to 36 months with the involvement of the right side in 7 cases and the left side in 6 cases. Four cases had dysgenesis of bony nasolacrimal duct (NLD), 4 cases had dacryolith, 3 cases had an intact membrane at the lower end of NLD and 2 cases had fibrosis of the lower end of NLD and the surrounding area in the inferior meatus (IM) following multiple interventions, (Table 1). Dacryoendoscopic recanalization was done in 7 cases while the endoscopic dacryocystorhinostomy (DCR) was done in 6 cases. Asuccessful outcome was achieved in all the cases and at the end of 6 months, all the children remained asymptomatic.Conclusions: Dacryoendoscopy (DEN) facilitates direct examination of the nasolacrimal system and thus has an added advantage over nasal endoscopy assisted probing in the refractory cases of CNLDO.

The Use of Anterograde Percutaneous Transluminal Coronary Angioplasty Balloons in Congenital Nasolacrimal Duct Obstruction: A Cost-Effective Alternative to the Traditional Dacryoplasty Balloons.

PURPOSE: To assess the efficacy of commonly available coronary angioplasty balloon catheters as a low-cost alternative to the traditional dacryoplasty catheters in select patients of congenital nasolacrimal duct obstruction. METHODS: A prospective, interventional study was performed between July 2018 and December 2018 in children with congenital nasolacrimal duct obstruction, who underwent balloon dacryoplasty using the coronary angioplasty balloon catheters (2.75 × 10 mm, SPALNO, Cardiomac, Haryana, India). The inclusion criteria were children ≥4 years of age, and/or previously failed probing and/or previous failed intubation. Parameters documented were demographics, techniques, costs, complications, and postoperative outcomes. RESULTS: Twenty-three eyes of 22 children underwent balloon dacryoplasty using coronary angioplasty balloon catheters. The mean age of the patients was 4.33 years (range 1.5-10 years). The procedure was performed in 8 patients (8 eyes, 35%) as the primary procedure. The remaining 14 patients (15 eyes, 65%) had a history of probing, of which 4 eyes had it twice earlier. All eyes underwent balloon dacryoplasty as per standard protocols. The insertion profile and trackability of the coronary catheters were good. At a mean follow up of 6.17 months (range 1.5-9 months), anatomical and functional success was obtained in 87% cases (n = 20/23). No lacrimal passage trauma or injuries were noted during the procedure. The cost of coronary balloon catheter was approximately $60. CONCLUSIONS: The present pilot study has shown that outcomes of balloon dacryoplasty in patients with congenital nasolacrimal duct obstruction with coronary balloon catheters is comparable to that of traditional balloons and offers significant economic advantage for developing nations.

Lacrimal sac rhinosporidiosis: case report and review of literature with a new grading system to optimize treatment.

Rhinosporidiosis is a chronic granulomatous disease affecting the mucous membrane primarily and is caused by Rhinosporidium seeberi, an aquatic protistan parasite. The nose is the most common site of involvement and is seen in 83.3% cases, followed by ocular involvement in 11.2% cases and other sites like larynx, trachea and bronchus in 5.5% cases. In various oculosporidiosis case series, lacrimal drainage system involvement was seen to vary from 14.3% to 59.6% cases. Isolated lacrimal sac involvement in rhinosporidiosis was found in 45.8% (72 out of 157) cases of the lacrimal drainage system in a review of 31 studies. A variety of surgical procedures have been used to treat rhinosporidiosis of lacrimal sac like dacryocystorhinostomy, Dacryocystectomy, lateral rhinotomy and local lesion excision with a success rate varying from 28.5% to 92.3%. This wide variation in the success rate was due to the fact that a uniform surgical procedure was performed in all the cases of a particular series irrespective of the extent of disease. Grading the lacrimal sac rhinosporidiosis to decide the extent of surgical excision may help achieve better results. We present a grading system based on our own experience in a case of extensive rhinospodiosis of lacrimal sac and review of 31 studies published in the literature. A 24-year-old male from Nepal presented with the complaints of watering from his right eye of 13 years duration, swelling in the right medial canthal area with an extension to the inferior part of the orbit for 12 years and nasal blockage for 1.5 years. The patient had a history of previous intervention in which biopsy was taken from the nose and sent for histopathology that confirmed rhinosporidiosis. An extended intranasal endoscopic dacryocystectomy was done along with debridement and coblation of the lesion over the septum and nasopharynx. Intraoperatively a large rhinosporidiosis mass was seen filling the sac and was removed in toto along with the sac and nasolacrimal duct. Recurrence of a tiny lesion after 6 months in our case despite wide excision with the drilling of bony nasolacrimal duct and coblation, made us review the literature.

Prevalence of buried probe in complex congenital nasolacrimal duct obstruction and evaluation of its success rate post 'probing and irrigation': a single-centre retrospective study.

INTRODUCTION: The aim of this study was to determine the prevalence of buried probe variant of complex congenital nasolacrimal duct obstruction (CNLDO) and to evaluate the outcome of probing and irrigation in such cases. Institutional review board approval was taken. MATERIAL & METHODS: A total of 309 eyes (258 patients) were diagnosed with CNLDO during the study period of January 2014-March 2017. A retrospective file review of 25 lacrimal systems of 20 patients diagnosed as buried probe variant of complex CNLDO was carried out during the study period. RESULT: Buried probe variant of complex CNLDO was found to be 8% of the total CNLDO cases during the study period. Mean age at presentation was 1.7 years (range 8-48 months). Discharge and matting of eyelashes were the presenting symptoms in 22 out of 25 (88%) cases, whereas the only epiphora was the presenting symptom in three (12%) cases. Regurgitation of mucopurulent discharge on pressure over lacrimal sac area was positive in 16 out of 25 (64%) eyes. Associated lacrimal and nasal pathologies were seen in six out of 25 cases (24%). Success rate in buried probe variant cases of CNLDO in our study at 3-month follow-up was 88% (22 of 25 cases). CONCLUSION: A high period prevalence of 8% out of all CNLDO cases in our study suggests that the buried probe should be considered in selective cases of CNLDO and earlier unsuccessful probing.

A comparison of the success rates of endoscopic-assisted probing in the treatment of membranous congenital nasolacrimal duct obstruction between younger and older children and its correlation with the thickness of the membrane at the Valve of Hasner.

Congenital nasolacrimal duct obstruction (CNLDO) remains the most common cause of epiphora in infants. This retrospective study compares the success rate of nasal endoscopic-assisted probing between younger (3 years and below) and older (above 3 years) children with membranous CNLDO and its correlation with the thickness of the membrane at the valve of Hasner. Case records of a total of 38 eyes in 34 children with membranous CNLDO who underwent endoscopic nasolacrimal duct probing and irrigation under general anesthesia were analyzed. The cases were divided into two groups, Group Y (20 cases of children 3 years and below) and Group O (18 cases of children above 3 years). The success of the procedure was defined as complete remission of symptoms and a clinical examination of eye to rule out the presence for discharge or watering after three months of the procedure. Overall, 35 cases (92.1%) were successfully treated with a success rate of 95% in Group Y and 88.9% in Group O. The mid-P exact test p value for the success rate between the two cohorts was not statistically significant (p = 0.59). The thick membrane was observed in 50% cases in Group Y and 33.33% cases in Group O (p = 0.34). There is no age related decline in the overall success rate for nasal endoscopic-assisted probing and irrigation in cases of membranous CNLDO. The thickness of the membrane may be a factor for failed blind probing, but it has no correlation with the success rate if probing is done under endoscopic guidance.

Mutations in the prostate specific antigen (PSA/KLK3) correlate with male infertility.

Prostate specific antigen (PSA/KLK3) is known to be the chief executor of the fragmentation of semenogelins, dissolution of semen coagulum, thereby releasing sperm for active motility. Recent research has found that semenogelins also play significant roles in sperm fertility by affecting hyaluronidase activity, capacitation and motility, thereby making PSA important for sperm fertility beyond simple semen liquefaction. PSA level in semen has been shown to correlate with sperm motility, suggesting that PSA level/activity can affect fertility. However, no study investigating the genetic variations in the KLK3/PSA gene in male fertility has been undertaken. We analyzed the complete coding region of the KLK3 gene in ethnically matched 875 infertile and 290 fertile men to find if genetic variations in KLK3 correlate with infertility. Interestingly, this study identified 28 substitutions, of which 8 were novel (not available in public databases). Statistical comparison of the genotype frequencies showed that five SNPs, rs266881 (OR = 2.92, P < 0.0001), rs174776 (OR = 1.91, P < 0.0001), rs266875 (OR = 1.44, P = 0.016), rs35192866 (OR = 4.48, P = 0.025) and rs1810020 (OR = 2.08, P = 0.034) correlated with an increased risk of infertility. On the other hand, c.206 + 235 T > C, was more freuqent in the control group, showing protective association. Our findings suggest that polymorphisms in the KLK3 gene correlate with infertility risk.
