Comparison Between Urine Dipstick and Microscopic Examination Urinalysis With Urine Culture to Evaluate the Sensitivity and Specificity for Each in Diagnosing Urinary Tract Infection in Qassim Region, Saudi Arabia.

BACKGROUND: Urinalysis is the most popular test for evaluating emergency room patients with possible urinary tract infections (UTIs). Due to their speed and inexpensive cost, urine dipsticks are frequently performed in the Emergency Room. Although a urine dipstick test may be less expensive and time-saving than a laboratory study, it may not be accurate. The study evaluated the sensitivity and specificity of urine dipstick and microscopic urinalysis with a urine culture. METHODOLOGY: A prospective, observational study was conducted on adults who visited the Emergency Department at King Fahd Specialist Hospital in Buraydah and reported having dysuria, urine urgency, or frequency, as well as suprapubic or costovertebral angle soreness. Patients who could not give a trustworthy history, had symptoms of vaginal discharge, or had taken antibiotics within the previous 72 hours were excluded. RESULTS: One hundred fifty-three urine samples were collected and examined using urinalysis and dipstick. In addition, 113 (73.86%) of 153 urine samples exhibited no growth in urine culture. With a count of nine, Escherichia coli (E. coli) was the most often isolated organism among the positive cultures (5.88%). Klebsiella pneumoniae was the second most common in our sample with eight (5.23%). The urine dipstick was shown to have an overall sensitivity of 0.79, specificity of 0.39, positive productive value (PPV) of 0.30, and negative productive value (NPV) of 0.85. Urinalysis exhibited a high sensitivity of 0.95 and a poor specificity of 0.21. CONCLUSION: Our study showed that urine dipsticks may be more beneficial than urinalysis for ruling out urinary tract infections (UTIs), while urinalysis may be more helpful in verifying their presence.

Mesenteric Panniculitis and COVID-19: A Rare Association.

Coronavirus disease 2019 (COVID-19) typically involves the respiratory system, but gastrointestinal involvement is common. Further, patients with severe COVID-19 are at high risk to develop gastrointestinal complications, including bowel ischemia, ileus, and deranged liver enzymes. We present the case of a 44-year-old woman with mild COVID-19 pneumonia who was in home isolation. Ten days after the isolation, the patient presented to the emergency department complaining of generalized abdominal pain that was sharp in nature and associated with nausea and recurrent episodes of vomiting. The patient did not complain of any respiratory symptoms. Physical examination showed diffuse tenderness with no clinical signs to suggest generalized peritonitis. The laboratory parameters showed normal hematological, renal, and hepatic profiles. No elevation in the inflammatory markers was observed. The amylase level was within the normal range. Abdominal computed tomography scan demonstrated the presence of misty mesentery with increased density of the mesentery with fat stranding encasing the mesenteric vessels along with mesenteric adenopathy. Such radiological features suggested the diagnosis of mesenteric panniculitis. Subsequently, intravenous corticosteroid therapy was initiated and the patient exhibited significant improvement after 24 hours. The patient was discharged after nine days of hospitalization. She was followed up after one month and she had no complaints. Mesenteric panniculitis is a rare idiopathic inflammatory condition involving the mesenteric adipose tissue. The case shed a light on the possible association of COVID-19 with mesenteric panniculitis. The clinical manifestations of mesenteric panniculitis are non-specific and imaging studies are essential to suggest the diagnosis.
