“…The large variability in the correlation coefficient between USG size and pathologic size in different studies means that USG measurements are highly dependent on the expertise of the person performing USG. [50][51][52][53][54] Because radiologic size helps tailor surgery in some cases, a better correlation would mean accurate decision regarding surgical procedure for the patient. Also, knowledge of factors influencing this concordance can be useful in regards to surgical planning.…”

Background: Radiologic assessment of tumor size is an integral part of the work-up for breast carcinoma. With improved radiologic equipment, surgical decision relies profoundly upon radiologic/clinical stage. We wanted to see the concordance between radiologic and pathologic tumor size to infer how accurate radiologic/ clinical staging is. Materials and methods: The surgical pathology and ultrasonography reports of patients with breast carcinoma were reviewed. Data were collected for 406 cases. Concordance was defined as a size difference within AE2 mm. Results: The difference between radiologic and pathologic tumor size was within AE2 mm in 40.4% cases. The mean radiologic size was 1.73 AE 1.06 cm. The mean pathologic size was 1.84 AE 1.24 cm. A paired t-test showed a significant mean difference between radiologic and pathologic measurements (0.12 AE 1.03 cm, p ¼ 0.03). Despite the size difference, stage classification was the same in 59.9% of cases. Radiologic size overestimated stage in 14.5% of cases and underestimated stage in 25.6% of cases. The concordance rate was significantly higher for tumors 2 cm (pT1) (51.1%) as compared to those greater than 2 cm (!pT2) (19.7%) (p < 0.0001). Significantly more lumpectomy specimens (47.5%) had concordance when compared to mastectomy specimens (29.8%) (p < 0.0001). Invasive ductal carcinoma had better concordance compared to other tumors (p ¼ 0.02). Conclusion: Mean pathologic tumor size was significantly different from mean radiologic tumor size. Concordance was in just over 40% of cases and the stage classification was the same in about 60% of cases only. Therefore, surgical decision of lumpectomy versus mastectomy based on radiologic tumor size may not always be accurate.

“…Medical ultrasound is increasingly used by non-radiology trained medical personnel due to widespread dissemination of affordable portable ultrasound equipment and need for urgent clinical decisions at the bedside. This leads to performance of ultrasound examination by nonradiology trained physicians in the emergency department or ICU without much quality assurance or standardized training system compared to traditional radiology (8). In most developed countries, a governing body stipulates the training requirement and licensure of sonographers and physicians (radiologist).…”

“…Several issues surrounding the sole use of ultrasonography for imaging in this study deserve recognition. This modality is known to be highly operator-dependent, 42 making precise assessment of its clinical accuracy through synthesis of evidence from various centers and periods theoretically challenging. Stones less than 5 mm are increasingly difficult to visualize, if seen at all, 19,43 and there are several vascular and nonvascular sonographic mimics that can be mistaken for a stone.…”

Context: While urolithiasis is epidemiologically and mechanistically linked to gout, urologic stone disease is not actively investigated in gout patients. Prevalence estimates on the coexistence of urolithiasis in gout have mostly relied on clinical history alone. Purpose: To estimate the prevalence of urolithiasis among adult Filipinos with primary gout through clinical history and ultrasonography. Patients and Methods: Patients diagnosed with primary gout were consecutively enrolled from outpatient clinics of the University of the Philippines Manila-Philippine General Hospital. Clinical data including sex; current age; age at diagnosis, duration of and attack frequency of gout; comorbidities such as hypertension, chronic kidney disease, type 2 diabetes mellitus, and dyslipidemia; personal history of urolithiasis; family history of gout; presence of tophus and laboratory samples to assess general kidney function, serum uric acid level, and urine pH were obtained from each patient who was subsequently subjected to ultrasonographic examination for urolithiasis. Lithiasic and non-lithiasic patients were identified and compared aggregately in terms of the aforementioned features. Results: We recruited 121 patients, 86.8% of whom are male, and 37 (30.6%; 95% CI=23.1-39.3%) were identified to have urolithiasis of which only 12 (9.9%) had history consistent with urolithiasis and 30 (24.8%) were diagnosed solely through ultrasonography. None of the variables of interest were found to be statistically associated (P>0.05) with urologic stone formation. Conclusion: Urolithiasis among adult Filipino patients with primary gout was found to be more prevalent in this study than previous estimates, which were based only on clinical history. We discovered that 25/37 (67.6%) of patients with urolithiasis denied history of urologic stone.
