"Smart Optometry" phone-based application as a visual acuity testing tool among pediatric population.

OBJECTIVES: To evaluate the validity of a smartphone-based application for visual acuity (VA) testing in children and to compare parent and clinician-performed VA to standard VA assessment. METHODS: A cohort of 100 children aged <18 years old was recruited. Subjects were randomly assigned to either start with conventional distance VA chart screening or the smartphone VA assessment twice by both the clinician and the caregiver if applicable. Near VA scores were assessed using the near vision E chart. Accuracy and reliability values were analyzed. RESULTS: One hundred patients with an average age of 9.92 ± 3.0 years old were enrolled. The difference between conventional distance and application logMAR values was -0.023, and the difference between near vision and application logMAR values was -0.004. "Smart Optometry" had a sensitivity of 89.3% in detecting subnormal VA compared with conventional vision testing methods. Sensitivity in detecting subnormal VA was found to be higher in younger age groups up to 91.7% in comparison with the older age groups. The interclass correlation of application-measured VA scores by the caregivers and the clinician were 0.77 (95% CI; 0.67-0.83) using single measures and 0.87 (95%CI; 0.8-0.9) using average measures. CONCLUSION: "Smart Optometry" phone application was found to be an acceptable home-based VA testing tool with good inter-rater reliability for young children showing good sensitivity in detecting subnormal VA, but lower sensitivity in detecting amblyopia.

The long-term impact of neck scar satisfaction among thyroid surgery patients.

This study evaluated scar satisfaction in Arabic patients who underwent thyroidectomy surgery using validated assessment tools. We aimed to assess the relationship between scar length and scar satisfaction, and validate Arabic versions of the universally used scar satisfaction questionnaires. In this retrospective cohort study, 60 patients who underwent thyroidectomy at King Abdulaziz University Hospital were enrolled. Scars were evaluated in two stages: firstly, by a clinician, and secondly, by a naïve observer. Ratings of disfigurement were measured using the validated Patient and Observer Scar Assessment Scale (POSAS) that was translated into Arabic. Results: The Arabic version of the POSAS showed good or excellent reliability. Average POSAS scores were 12.88, 18.02, and 7.53, respectively, indicating that most patients were satisfied. Incision size and POSAS scores (but not Patient and Naïve Observer scores) were positively correlated, and larger incisions resulted in greater dissatisfaction. Fitzpatrick Skin Type score and Observer scores were positively correlated, but there were no significant correlations between Patient and Naïve Observer scores with skin type. In conclusion, this study validated the Arabic version of universally used questionnaires for scar satisfaction. Most patients were satisfied with their neck scars regardless of scar length. Our findings pave the way for further research into patient postoperative scar satisfaction in Arabic-speaking populations.

Colonic Gallstone Ileus: A Rare Etiology of Large Bowel Obstruction.

Large bowel obstruction is a surgical emergency that requires prompt diagnosis and management. It is frequently caused by colon cancer. However, the common benign etiologies include volvulus, hernia, adhesions, and strictures. Imaging studies are essential to establish the diagnosis and identify the etiology. We present the case of a 44-year-old female who presented to the emergency department with abdominal pain and distension for a one-week duration. The pain was associated with decreased bowel motions and vomiting. Her past medical history was significant for diabetes mellitus, dyslipidemia, polycystic ovarian syndrome, and recurrent episodes of biliary colic. Upon examination, she had tachycardia, normal temperature, and normal blood pressure. Abdominal examination revealed a distended abdomen with generalized tenderness and increased intensity of bowel sounds. The laboratory markers were noncontributory. Abdominal computed tomography (CT) scan of the abdomen with intravenous contrast demonstrated the presence of an oval-shaped hypodense intraluminal mass in the sigmoid colon where there was a transition point with proximal colonic dilatation. There was an abnormal communication between the gallbladder and the colon at the hepatic flexure, representing a cholecystocolic fistula tract. This represents a mechanical obstruction of the large bowel due to migrated gallstone through a cholecystocolic fistula tract. The patient was prepared for an emergency laparotomy. The gallstone was removed, and the sigmoid colon was sutured primarily. Resection of the gallbladder was made with the closure of the fistula tract. Following the surgery, the patient reported a resolution of her abdominal pain. Oral feeding was started gradually. After six months of close follow-up, the patient remained asymptomatic with no new complaints. Cholecystocolic fistula is a very rare complication of gallbladder disease. Despite its rarity, surgeons should remember this etiology of large intestinal obstruction when they encounter a patient with gallbladder disease.
