Factors affecting compliance to intravitreal anti-vascular endothelial growth factor therapy in Indian patients with retinal vein occlusion,age-related macular degeneration,and diabetic macular edema

Purpose:To evaluate the rate of compliance and the reasons for loss to follow-up in Indian patients with diabetic macular edema (DME), age-related macular degeneration (AMD), and retinal vein occlusion (RVO) being treated with anti-vascular endothelial growth factor (VEGF) therapy.Methods:This was a retrospective single-center study. Patients with DME, AMD, or RVO were eligible if they initiated anti-VEGF therapy between January 2013 and December 2017. Patients'' data were obtained from hospital electronic records, including the number of injections received, visits, details of follow-up, missed appointments, and reasons for loss to follow-up (>365 days).Results:A total of 648 patients were eligible for the study, of which 334 (51.54%) patients were lost to follow-up. Overall, 343 (64.96%) were males and the overall mean (SD) age was 66.40 (7.44) years. A total of 376 (58.0%) patients had a history of diabetes and 364 (56.2%) patients had a history of hypertension. Further, 127 (38.0), 112 (33.5), and 95 (28.4) had DME, AMD, and RVO, respectively and were lost to follow-up. The most commonly reported reason for loss to follow-up was “non-affordability” (n = 120; 41.1%) followed by “no improvement in vision” (n = 83; 28.4%). “No improvement in vision” (42.2%) and “non-affordability” (37.5%) were higher among patients with DME. No association was found in gender- and treatment-wise distribution of reasons for loss to follow-up.Conclusion:The results showed that around half of the patients with DME, AMD, and RVO were lost to follow-up to intravitreal anti-VEGF therapy, and the most common factors were “non-affordability” and “no improvement in vision.”     

Soft tissue healing after parasagittal palatal incisions in segmental maxillary surgery: a review of 311 patients.

PURPOSE: This study retrospectively evaluated the soft tissue healing after using parasagittal soft tissue incisions for surgical segmental maxillary expansion. PATIENTS AND METHODS: The records of 311 patients (224 females, 87 males), with an average age of 28.5 years (range, 12 to 62 years) who had transverse maxillary hypoplasia, were retrospectively evaluated. All patients underwent segmental maxillary osteotomies, surgical maxillary expansion greater than 5 mm, and placement of midpalatal porous block hydroxyapatite (PBHA). Parasagittal palatal soft tissue incisions were used to facilitate expansion, minimize soft tissue damage, and maintain soft tissue coverage over the PBHA implants. At postoperative follow-up visits, any signs or symptoms of complications associated with the use of the parasagittal incisions were recorded. RESULTS: Average patient follow-up was 3.4 years (range, 1.0 to 7.2 years). In 293 patients (94%), the palates healed uneventfully without complications. Eighteen patients (6%) had complications; 9 (2.9%) had infections associated with the midpalatal implants, 8 (2.6%) had oronasal communications, and 1 (0.3%) had problems associated with a palatal wire. Six patients with midpalatal implant problems required removal of the implant, 4 patients required closure of their oronasal communications, and 1 patient required removal of a palatal wire. Therefore, 11 patients (3.5%) required minor secondary surgical procedures. No teeth or alveolar bone were lost in any of the cases. CONCLUSIONS: The use of parasagittal palatal incisions appears to be a safe technique for soft tissue management during large surgical maxillary expansions associated with segmental maxillary osteotomies and midpalatal placement of PBHA implants.     

Elective laparoscopy for herald symptoms of mesenteric/internal hernia after laparoscopic Roux-en-Y gastric bypass

BackgroundMesenteric internal hernia (MIH) is the most common cause of small bowel obstruction (SBO) after laparoscopic Roux-en-Y gastric bypass. Because MIH is a potentially life-threatening complication, we hypothesized that elective repair of MIH before developing acute SBO could decrease morbidity in this population.MethodsThe records of 702 consecutive patients undergoing primary laparoscopic Roux-en-Y gastric bypass from January 2002 and August 2007 were retrospectively reviewed to determine the incidence and etiology of SBO. During the last 9 months of the study, we offered elective laparoscopy to any patient who presented to us with symptoms of intermittent SBO.ResultsOf the 702 patients, 27 (3.8%) developed acute SBO. Of these 27 patients, 15 (55%) had obstruction related to an MIH. Nearly all patients had a typical history of intermittent abdominal pain, nausea, and bloating before developing acute SBO. Elective laparoscopy was offered to 11 patients with symptoms of intermittent SBO. Two patients who refused subsequently underwent operations for acute SBO. MIH was found at elective laparoscopic exploration in all cases. Of the 9 patients undergoing elective surgery, 3 (33%) had small bowel volvulus.ConclusionSBO due to MIH after laparoscopic Roux-en-Y gastric bypass is typically preceded by symptoms of intermittent obstruction. Patients who have these herald symptoms should promptly be offered elective laparoscopic exploration. Elective repair of MIH can be performed safely and expeditiously.     

Nitrobid therapy in sudden sensorineural hearing loss

The efficacy of local application of Nitrobid oinment in the treatment of idiopathic sudden sensorineural hearing loss has been presented Overall good to fair recovery occured in 40% of the patients, important prognostic indicators were found to be severity of initial hearing loss, time from onset to initial visit, age of the patient and hearing status of the opposite ear.     

Brainstem Evoked Response audiometry in diabetes mellitus

This study was undertaken to record the Brainstem Evoked Responses in a group of 20 diabetic patients with normal hearing and were compared with responses of another group of 20 normal individuals. Eighth nerve transmission till the level of cochlear nucleus was found to be normal in diabetics. The delay in latency of Wave III, IV and V and interpeak latencies (I–III, I–V) were noted to be statistically significant, thus suggesting the presence of central neuropathy in patients with diabetes. No significant sex difference on latency of waves was observed.
