Comparison of glaucomatous from non-glaucomatous optic neuropathy using Bruch’s membrane opening minimum rim width optical coherence tomography measurements

Purpose: To compare glaucomatous from non?glaucomatous optic atrophy using optical coherence tomography (OCT) based on the measurement values of Bruch’s membrane opening minimum rim width (BMO?MRW), which is a difficult task otherwise due to their varied course of disease progression, treatment protocols, and systemic association to visual impairment. Methods: This study was conducted in 40 eyes, comprising 20 eyes with non?glaucomatous optic neuropathy (NGON) and 20 eyes with glaucomatous optic neuropathy (GON). All patients underwent a complete ophthalmic examination followed by an OCT optic disc scan to calculate the measurement of BMO?MRW. Results: The 5?fold cross?validated area under the curve for GON versus NGON from logistic regression models was 0.95 (95% confidence interval [CI]: 0.86–1.00) using BMO?MRW values from all sectors. The results revealed that the measurements were significantly lesser in GON than in NGON patients. Conclusion: Hence, OCT?based BMO?MRW values could be used as an additional test to compare glaucomatous with non?glaucomatous optic neuropathy patients, especially in cases of high clinical suspicion.

Evaluation of the radiofrequency ablation of lumbar sympathetic ganglia in lower limb ischemic ulcers in indian population: radio frequency ablation and lower limb ischemic ulcers / Evaluación de la ablación por radiofrecuencia de los ganglios simpáticos lumbares en las úlceras isquémicas de las extremidades inferiores en la población de la India: ablación por radiofrecuencia y úlceras isquémicas de las extremidades inferiores

Background:Lumbar sympathectomy through radio ablation is a useful treatment of peripheral ischemia. However, clinical efficacy with respect to lower limb ulcers is not adequately established in the Indian population. The study was conducted to evaluate the role of radiofrequency ablation (RFA) of the lumbar sympathetic ganglia in healing of ischemic ulcers of the lower limb.Method:The prospective study with 63 patients registered in the General surgery department with lower limb ischemic ulcers between December 2017­ July2019 were treated with RFA. Patients with cardiopulmonary disease, pregnant, congenital malformation, or skin infection at the site of intervention, or suffering from bleeding disorders, were excluded from the study. Clinical investigation of the wound was performed, and demographic data was collected. Comparative reduction in wound size was assessed through Friedman`s ANOVA (P<0.001). Difference in pain score, hospital stay, and walking distance were evaluated using Wilcoxon matched pair test (P<0.001), Unpaired t-test, and Paired t-test (P<0.05).Result:Majority of the patients were male (n=40) with a mean age of 60.93 SD14.34 years. Significant reduction in wound size, pain scores and hospital stay were observed post procedure(P<0.001). Number of RFA sessions was significantly associated with the size of the ulcer and Fontaine's classification 2 and 3 (P<0.0001).Conclusion:RFA of lumbar sympathetic ganglia is a potential treatment modality for lower limb ischemic ulcers.

Antecedentes: La simpatectomía lumbar a través de la ablación por radiofrecuencia es un tratamiento útil de la isquemia periférica. Sin embargo, la eficacia clínica con respecto a las úlceras en las extremidades inferiores no está adecuadamente establecida en la población india. El estudio se llevó a cabo para evaluar el papel de la ablación por radiofrecuencia (RFA) de los ganglios simpáticos lumbares en la curación de las úlceras isquémicas de la extremidad inferior. Método: El estudio prospectivo con 63 pacientes registrados en el departamento de cirugía general con úlceras isquémicas de las extremidades inferiores entre diciembre de 2017 y julio de 2019 fueron tratados con RFA. Los pacientes con enfermedad cardiopulmonar, malformación embarazada, congénita o infección de la piel en el lugar de la intervención, o que sufren de trastornos hemorrágicos, fueron excluidos del estudio. Se realizó una investigación clínica de la herida y se recopilaron datos demográficos. La reducción comparativa en el tamaño de la herida se evaluó a través del ANOVA de Friedman (P<0.001).Resultado: La diferencia en la puntuación del dolor, la estancia en el hospital y la distancia a pie se evaluaron mediante la prueba de par coincidente de Wilcoxon (P<0.001), la prueba t no emparejada y la prueba t emparejada (P<0.05). La mayoría de los pacientes eran varones (n-40) con una edad media de 60,93 SD14,34 años. Se observó una reducción significativa en el tamaño de la herida, las puntuaciones de dolor y la estancia hospitalaria (P<0.001). El número de sesiones de RFA se asoció significativamente con el tamaño de la úlcera y las clasificaciones 2 y 3 de Fontaine (P<0.0001).Conclusión: LA RFA de los ganglios simpáticos lumbares puede constituir una opción terapéutica para las úlceras isquémicas de las extremidades inferiores.

Cultural influence in the development of delusional parasitosis: A case report.

Delusional parasitosis is a rare condition in which the patient has a false and unshakable belief of being infested by parasites. Delusional parasitosis was classified as a subtype of monosymptomatic hypochondriacal psychosis in old literature. Though the delusion is considered to be primary, at times it is described as an elaboration of a primary pathological experience such as a tactile hallucination, paresthesia or pruritus. Although several cases of delusional parasitosis have been reported, the role of cultural belief systems and native treatments in turning an idea into a delusional disorder has not been adequately studied. This paper reports a case of delusional parasitosis in which cultural factors played a major role in shaping the delusion. The case was effectively managed with risperidone.

Prevalence of Methicillin Resistant Staphylococcus aureus (MRSA) Nasal carrier in Health Care Workers.

Methicillin resistance Staphylococcus aureus (MRSA) is an important nosocomial pathogen that causes severe morbidity and mortality worldwide. In recent years, nosocomial outbreaks of methicillin resistance Staphylococcus aureus (MRSA) has become a major infection control problem. Colonized employees are generally asymptomatic; they are a potential reservoir and disseminator of MRSA in hospitals. Nasal screening of health care workers (HCW) for MRSA is performed routinely in several countries, typically when more than one MRSA – colonized patient is identified in high risk ward, such as intensive care unit (ICU). This study was performed at PSG Hospitals to assess the prevalence of MRSA nasal colonization in health care workers and their sensitivity pattern. The prevalence of MRSA carriage among HCW’s was quite low (3.3%) in our institution. It has been recommended that, in case of epidemic in the hospital, all health care workers should be examined for MRSA colonization.

Treatment of gingival recession by modified Langer and Langer technique.

In recent years, stronger need for esthetics and growing cosmetic demand for a pleasing smile has made many individuals more conscious of the recession on facial aspect of the teeth. Here we report a case illustrating treatment for facial gingival recession using modified Langer and Langer technique. The clinical results showed good soft tissue coverage of the root surfaces and improving esthetics.
