The burden of avoidable blindness from corneal disease is significantly higher where access to specialist eye care, the cost of treatment and the treatment infrastructure including eye banking, are beyond the reach of the impoverished masses. Corneal transplantation in children is challenging: it is more technically complex; patients often require multiple examinations under general anaesthesia to optimize treatment outcomes. There is also the increased risk of several complications including graft dehiscence, infection, rejection, and inappropriate patient or caregiver care. ⋯ Corneal graft tissue remained clear at more than 3 years of follow-up. Although amblyopia was a notable co-morbidity, corneal transplantation significantly improved their vision. Corneal banking services are advocated for in resource-limited settings where the magnitude of corneal blindness is greatest.

The physical examination is a key part of a continuum that extends from the history of the present illness to the therapeutic outcome. An understanding of the pathophysiological mechanism behind a physical sign is essential for arriving at the correct diagnosis. Early detection of deteriorating physical/vital signs and their appropriate interpretation is thus the key to achieve correct and timely management. ⋯ Considering these benefits of SaO2 measurement, there have been several references in the past to consider oxygen saturation as the fifth vital sign. In the present pandemic oxygen saturation i.e., SpO2 (arterial oxygen saturation) measured by pulse oxymeter, has been the single most important warning and prognostic sign be it for households, offices, street vendors, hospitals or governments. Measurement of trends of SaO2 added with respiratory rate will provide clinicians with a holistic overview of respiratory functions and multidimensional conditions associated with hypoxemia.

Observational Study
Prevalence of Doppler-Derived Left Ventricular Diastolic Dysfunction Among Newly Diagnosed Hypertensive Patients.
The initial sign of hypertensive heart disease (HHD) is left ventricular diastolic dysfunction (LVDD), which is caused by remodeling of the left ventricle and left atrium, resulting in impaired relaxation of the left ventricle. LVDD is also partly due to left ventricular hypertrophy (LVH). If left untreated, LVDD can progress to diastolic heart failure and systolic heart failure. In Western countries, the prevalence of LVDD in long-term hypertensive patients ranges from 40.3% to 60%, but it is more common among hypertensive Nigerians. Since systemic hypertension can be asymptomatic in the early stages, it is important to evaluate LVDD early and control blood pressure to slow down its progression. ⋯ LVDD is highly prevalent among newly diagnosed hypertensive patients, with stage 1 being the most common. Female gender, older age, higher BMI, higher blood pressure, higher LAVI, and higher LVMI were significant predictors of LVDD. Early detection and appropriate management of LVDD may help to prevent adverse cardiovascular outcomes in hypertensive patients.

Corneal diameter (CD) measurement in newborns is essential for the detection of blinding ocular pathologies. It requires specially trained personnel, contact techniques, and the use of anesthesia. Smartphone use may obviate these challenges. ⋯ Corneal diameter measurement in neonates using smartphone technology does not deviate significantly from caliper measurement; it is safe, easy to use, and advocated.

The proximal femur geometry determines the hip force distribution. The femoral neck axis length (FNAL), the hip axis length (HAL), the femoral head diameter, and the femoral neck-shaft angle (FNSA) could influence the risk and outcome of pertrochanteric fractures. Restoring these parameters to their prefracture values could predict early hip function. ⋯ There is a significant difference in the FNSA between the unaffected and the operated hips. The FNSA significantly predicts the early hip function and should be reconstructed to within normal range during surgery.
