A Case Series of Positional Variations in the Spine of Henle: A Surgical Conundrum.

The temporal bone is a complex anatomical space that houses the middle ear and its ossicles, as well as the inner ear, which includes the vestibule, cochlea, and the semicircular canals. Henle's spine, also known as the suprameatal spine/spina suprameatica/ is found to guide the lateral wall of the mastoid antrum [J Res Med Dent Sci 8(7):420-422, Stat-Pearls Publishing, Treasure Island. Available from: https://www.ncbi.nlm.nih.gov/books/NBK559153/]. It is found that the Henle's spine is present in 85% of the human skulls and when present, it could be used as a reliable anatomical landmark for isolating various foramina during skull base surgeries [J Laryngol Otol 119:856-861], and to assess the location of handle of malleus and subsequently the mastoid antrum, in many cases. We present here 3 cases in which tympanoplasty was planned, and the position of spine of Henle was found to be anterosuperior and so was the handle of malleus. Antrostomy was done by following the spine of Henle in all cases to establish patency and maintain ventilation in the post-operative ear. These 3 cases had a much more anteriorly placed spine. Such cases need to be reported so that it creates a paradigm shift in the way that mastoid surgeries are being done. Any variation in the positioning of the spine of henle points to variability in the position of the mastoid antrum. This is extremely important while drilling the mastoid in the correct position and also to prevent drilling over the sigmoid sinus or the dura. To conclude, an anteriorly placed spine of Henle corresponds to anteriorly placed mastoid antrum.

Cosmetic evaluation of surgical scars after external dacryocystorhinostomy.

AIM: To evaluate the surgical scars of external dacryocystorhinostomy (DCR) cosmetically. METHODS: Totally 50 consecutive cases of primary acquired nasolacrimal duct obstruction (PANDO) were included in the study. Surgical scars were assessed by the patients and two independent observers at 2, 6 and 12wk postoperatively on the basis of visibility of the scars and still photographs respectively and were graded from 0-3. Kappa test was utilised to check the agreement of scar grading between the two observers. Wilcoxan signed ranks test was used to analyse the improvement of scar grading. RESULTS: Thirty-four (68%) patients graded their incision site as very visible (grade 3) at 2wk. At 6 and 12wk, incision site was observed as grade 3 by 7 (14%) and 1 (2%) patients respectively. Photographic evaluation of patients by 2 observers showed an average score of 2.75, 1.94 and 0.94 at 2, 6 and 12wk respectively. Change in scar grading from grade 3 to grade 0 in consecutive follow-up (2, 6 and 12wk) was found to be highly significant both for the patient as well for the observers (P<0.0001). CONCLUSION: The external DCR is a highly effective and safe procedure and in view of low percentage of cases who complained of marked scarring in the present study, thus scarring should not be the main ground for deciding the approach to DCR surgery, even in young cosmetically conscious patients.

Intratendinous Ganglion Cyst of the Semitendinosus Tendon: First Reported Case and Literature Review.

INTRODUCTION: Ganglion cysts are commonly seen in wrist joints and knee joint, but intra-tendinous ganglion cysts are extremely rare. We report the first case of intratendinous ganglion cyst of semi-tendinous tendon. CASE REPORT: A 4-year-old boy presented with painless soft tissue swelling over knee with no history of recent trauma. Radiograph was normal and USG showed a well-defined hypoechoic cystic lesion. Patient was taken for surgery and the lesion was removed. Lesion came out to be a ganglion cyst originating from the semitendinosus tendon. Post-operative USG was done to confirm complete removal of the ganglion. CONCLUSION: Intra-articular ganglion cysts are common, and we find it regularly in our daily practice. However, we should be aware of the occurrence of intratendinous ganglion cysts also which on examination may look like a lipoma. Thus for all cysts around the tendons, an USG is must. Also repeat USG should be done to rule out incomplete excision and recurrence.

Value of interactive scanning for improving the outcome of new-learners in transcontinental tele-echocardiography (VISION-in-Tele-Echo) study.

BACKGROUND: Point-of-care (POC) echocardiography may be helpful for mass triage, but such a strategy requires adequately trained sonographers at the remote site. The aim of this study was to test the feasibility of using a novel POC echocardiography training program for improving physicians' imaging skills during preanesthetic cardiac evaluations performed in a community camp organized for treating cataract blindness. METHODS: Seventeen physicians were provided 6 hours of training in the use of POC echocardiography; nine were taught on site and eight were taught online through a transcontinental tele-echocardiography system. The trained physicians subsequently scanned elderly patients undergoing cataract surgery. The quality of images was graded, and agreement between local physicians' interpretations and Web-based interpretations by worldwide experts was compared. RESULTS: A total of 968 studies were performed, with 660 used for validating physicians' competence. Major cardiac abnormalities were seen in 136 patients (14.2%), with 32 (3.3%) deemed prohibitive to surgery in unmonitored settings. Although good-quality images were obtained more frequently by physicians trained on site rather than online (P = .03), there were no differences between the two groups in agreement with expert interpretations. The majority of physicians (70.6%) expressed satisfaction with the training (average Likert-type scale score, 4.24 of 5), with no difference seen between the two groups. The training resulted in significant improvements in self-perceived competence in all components of POC echocardiography (P < .001 for all). CONCLUSIONS: This study establishes the feasibility of using short-duration, one-on-one, personalized transcontinental tele-echocardiography education for wider dissemination of echocardiographic skills to local physicians in remote communities, essential for optimizing global cardiovascular health.

American Society of Echocardiography: Remote Echocardiography with Web-Based Assessments for Referrals at a Distance (ASE-REWARD) Study.

BACKGROUND: Developing countries face the dual burden of high rates of cardiovascular disease and barriers in accessing diagnostic and referral programs. The aim of this study was to test the feasibility of performing focused echocardiographic studies with long-distance Web-based assessments of recorded images for facilitating care of patients with cardiovascular disease. METHODS: Subjects were recruited using newspaper advertisements and were prescreened by paramedical workers during a community event in rural north India. Focused echocardiographic studies were performed by nine sonographers using pocket-sized or handheld devices; the scans were uploaded on a Web-based viewing system for remote worldwide interpretation by 75 physicians. RESULTS: A total of 1,023 studies were interpreted at a median time of 11:44 hours. Of the 1,021 interpretable scans, 207 (20.3%) had minor and 170 (16.7%) had major abnormalities. Left ventricular systolic dysfunction was the most frequent major abnormality (45.9%), followed by valvular (32.9%) and congenital (13.5%) defects. There was excellent agreement in assessing valvular lesions (κ = 0.85), whereas the on-site readings were frequently modified by expert reviewers for left ventricular function and hypertrophy (κ = 0.40 and 0.29, respectively). Six-month telephone follow-up in 71 subjects (41%) with major abnormalities revealed that 57 (80.3%) had improvement in symptoms, 11 (15.5%) experienced worsening symptoms, and three died. CONCLUSIONS: This study demonstrates the feasibility of performing sonographer-driven focused echocardiographic studies for identifying the burden of structural heart disease in a community. Remote assessment of echocardiograms using a cloud-computing environment may be helpful in expediting care in remote areas.

Rapid Screening for Subclinical Atherosclerosis by Carotid Ultrasound Examination: The HAPPY (Heart Attack Prevention Program for You) Substudy.

BACKGROUND: Cardiovascular disease (CVD)-related death rates have been escalating in emerging economies such as India. A strategy to initiate prophylactic medical intervention by direct identification of subclinical atherosclerotic burden may be appropriate in rural populations where assessment based on traditional risk factors is not available. OBJECTIVES: This study sought to investigate the feasibility of performing rapid automated carotid ultrasound studies in a rural setting and to measure the prevalence of carotid plaques and age-specific distribution of carotid intima-media thickness (IMT) as an index of subclinical atherosclerosis. METHODS: Screening of the extracranial carotid system with automated B-mode ultrasound was performed along with health questionnaire assessments in 771 asymptomatic volunteers (ages 40 ± 14 years; 626 men and 145 women) with no known CVD. Measurements of IMT were recorded as the mean of 24 spatial measurements performed over a 1-cm region in the far wall of the common carotid artery at end diastole; the prevalence of the plaque (focal IMT >1.5 mm) was determined. RESULTS: A total of 69 (8.9%) subjects had atherosclerotic plaques. Of these, 16 (2.1%) exhibited bilateral plaques, 28 (3.6%) left carotid plaque only, and 25 (3.2%) had right carotid plaques. Patients even under 50 years showed a high prevalence of carotid plaques (7%), which increased with age (25% and 35% for 51 to 70 and >70 years, respectively). Only 3 (4.3%) participants with plaques were former smokers. Global mean IMT was 0.55 ± 0.13 mm and correlated with age for both left and right carotid arteries (r = 0.61 and 0.60, p < 0.001 for both) in male as well as female subjects (r = 0.70 and 0.67, p < 0.001 for both), respectively. CONCLUSIONS: Rapid community screening for subclinical atherosclerosis is feasible with automated carotid ultrasound examination and may be beneficial in rural communities of industrializing nations where traditional CVD risk factor data are not yet readily available.
