Implication of photic sneeze reflex in ophthalmology

Background: Photic sneeze reflex (PSR) also known as autosomal dominant compelling helioophthalmic outburst is a rare condition characterized by uncontrolled sneezing in response to bright light. The exact mechanism causing this is poorly understood. However, various hypotheses have been proposed. Ophthalmic examination involves exposing the patient to bright light like slit lamp, indirect ophthalmoscopy and surgical microscope, which can trigger sneezing in PSR patients. Purpose: The purpose of this video is to draw light to this rare phenomenon and its implication in ophthalmic surgery. Synopsis: A 74?year?old male patient presented with diminution of vision in left eye. On routine slit lamp and IDO examination, patient had repeated sneezing. We diagnosed him to have photic sneeze reflex. He had pseudophakic bullous keratopathy in the right eye and senile immature cataract in the left eye. Taking into consideration his one eyed status and PSR, measures were taken accordingly and cataract surgery was performed uneventfully. We describe in this video the challenges encountered with this phenomenon and approach in such cases. Highlights: In this video, we tried to give an idea about photic sneeze reflex and its theories. Also, we tried to bring out the impact of PSR on ophthalmologic practice.

Frailty as a predictor of outcome in heart failure in the elderly: An observational study at a tertiary care center

Introduction: Heart failure is the leading contributor to global morbidity and mortality. Frailty is an emerging prognostic factor in heart failure. There is little data on the prognostic role of frailty in patients admitted for acute heart failure as most studies have been done on stable heart failure patients. Methodology: The study included elderly (age ≥60 years) patients admitted with acute heart failure at a tertiary care center in India. Patients with dementia, cognitive impairment, and documented terminal illness were excluded. The sample size was 85 patients. Frailty assessment was done using short performance physical battery (SPPB) and Fried phenotype scales and follow‑up data was collected at 3 months postdischarge telephonically. The primary objective of the study was to determine the proportion of frailty in elderly in‑hospital heart failure patients. The secondary objectives were to see the agreement between the frailty assessment tools used (SPPB and Fried phenotype). Results: Eighty seven patients were included in the study. The majority were male (n = 45) and had heart failure with reduced ejection fraction (n = 56). Coronary artery disease (CAD) (n = 60) was the most common cause of heart failure. Eighty-two patients had at least one comorbidity. The proportion of frailty as per the SPPB was 43.67%, and as per the Fried phenotype was 68.9%. A total of 4 deaths and 15 re-admissions occurred during the follow-up period of 3 months. The majority belonged to the frail category as per both the frailty scales (P < 0.001 for SPPB, P = 0.087 for Fried phenotype). Fleiss’s kappa coefficient for agreement between the scales was 0.373 (SE = 0.106, P < 0.001), which signifies that there was a fair agreement between the two scales. The Spearman Rank correlation coefficient was −0.691 (P < 0.01) between the two scales. Hence, the SPPB score inversely correlated with the Fried phenotype. Conclusion: Frailty is largely prevalent in elderly heart failure patients. It can be used to predict poor outcomes in these patients. Clinicians should identify these high-risk patients at the time of discharge from their facility and consider interventions (tailored rehabilitation programs) to minimize the adverse outcomes.

Bilateral macular hole secondary to remote lightning strike.

We report a case of a 16-year-old girl, who was struck by lightning, and experienced blurred vision in the right eye (RE) immediately following the episode. She reported for ophthalmic evaluation two months later. Examination revealed relative afferent pupillary defect in the RE. Posterior subcapsular cataract was noted in both eyes. Fundus examination revealed macular holes and multiple areas of RPE hyperpigmentation in the periphery in both eyes. Fundus fluorescein angiography showed increased choroidal transmission with early fluorescence and late fading in the foveal region and retinal pigment epithelium (RPE) stippling in the periphery in both eyes. This is the first case report of such nature in India to the best of our knowledge.

Catatonic Syndrome – A Review.

Catatonia is common in clinical practice, though prevalence of affected patients has decreased over time. It is a syndrome with varies etiologies. Causative factors range from schizophrenia, depression, drug induced adverse effects to organic causes. It may present in two forms: stuporous and excited. Schizophrenia is thought to the most common cause, however, evidence suggest that it is more common in depression. Successful treatment of catatonia with lorazepam supports it.
