Are the current nomograms sufficient to predict shockwave lithotripsy outcomes?

INTRODUCTION AND OBJECTIVES: To investigate factors affecting SWL outcomes, validate three current nomograms (Kim JK, Triple D and S3HoCKwave) and compare the predictive ability of the nomograms for SWL outcomes in upper urinary tract stones. PATIENTS AND METHODS: Medical records of patients with renal and proximal ureteral stones treated with SWL between March 2013 and October 2020 were retrospectively reviewed. Factors affecting SWL success were analyzed with multivariate logistic regression analysis and the three predictive scoring systems compared with the area under the curve (AUC). RESULTS: A total of 580 patients were included in our study. The overall stone free rate was 61% and 144/580 patients (24.8%) were stone free after one session. In multivariate logistic regression analysis, stone location at upper calyx (OR:2.988; 95%Cl: 1.350-6.612; p = 0.007), middle calyx (OR:3.036; 95%Cl: 1.472-6.258; p = 0.003), and lower calyx (OR:2.131; 95%Cl: 1.182-3.839; p = 0.012), as well as number of stones (OR:1.663; 95%Cl: 1.140-2.425; p = 0.008), maximum diameter of stone (OR:1.156; 95%Cl: 1.098-1.217; p < 0.001) and maximum Hounsfield Unit (OR:1.001; 95%Cl: 1.001-1.002; p < 0.001) were independent risk factors of SWL failure. The AUCs of the Kim JK, Triple D and S2HoCKwave scores for predicting SWL success were 0.678, 0.548, and 0.626 respectively. CONCLUSIONS: Stone location, number, maximal diameter, and maximum HU were independent predictive factors for SWL outcome in the treatment of upper urinary tract stones. Current nomograms, "Kim JK nomogram", "Triple D score" and "S3HoCKwave score" can predict treatment success after SWL, but all of them have poor discrimination according to AUC analysis.

Intracavitary cardiac hydatid cysts with a high risk of thromboemboli. Invasive nature of cardiac echinococcosis.

Hydatid cysts are a serious health problem in many countries that raise farm animals, and they usually involve the liver and lungs. Although cardiac involvement is a rare manifestation of hydatid cyst disease, its early diagnosis and surgical management are crucial. Patients with cardiac hydatidosis may develop acute life-threatening complications secondary to their invasion of surrounding cardiac structures, such as cyst rupture together with systemic and pulmonary dissemination. Therefore, surgical excision is the definitive method of treatment for cardiac hydatid cysts in order to prevent these potential life-threatening complications, even for asymptomatic patients. Herein, we report the case of a 36-year-old man who initially presented with pleuritic chest pain, hemoptysis, and dyspnea. This was followed by the revelation of multiple cardiopericardial hydatid cysts which were discovered via transesophageal echocardiography and multislice computed tomography. In this case, there was a higher risk of cyst rupture and thromboembolism during systemic and pulmonary circulation due to the invasive nature of the cysts which were located in the left atrium as well as between the pulmonary artery and aorta. The patient successfully underwent the removal of the multiple cardiac cysts under cardiopulmonary bypass by taking into account their relationship with the surrounding cardiac structures and the potential risk of local, systemic, and pulmonary dissemination. A pathological evaluation of the surgical specimens confirmed the diagnosis of cardiac echinococcosis and the aggressive nature of the cardiopericardial hydatid cysts by demonstrating their myocardial invasion.

Unusual localization of a primary superficial venous aneurysm: a case report.

OBJECTIVES: Primary aneurysms of superficial venous system are rare and frequently misdiagnosed as varicose veins. Clinical presentation is variable depending on the presence of compression to surrounding structures. We report a rare case of primary cephalic vein aneurysm presented with wrist pain due to radial nerve compression. METHOD/CASE: A 61-year-old woman was admitted with right wrist pain and localized mass. Physical and imaging examinations showed a localized cephalic vein aneurysm compressing radial nerve. Simple excision was performed successfully. RESULTS: Cosmetic and clinical results at the first month follow-up were successful. DISCUSSION: Although primary superficial venous aneurysms of upper extremities are very rare, the treatment of choice is most commonly same as the ones in lower limbs. Simple excision is the best approach in the most of the cases, while sclerotherapy could be preferred in order to obtain better cosmesis or to avoid injuries to surrounding structures.

Increased epicardial fat thickness is related with body mass index in women with polycystic ovary syndrome.

AIM: We aimed to investigate the relationship between PCOS and epicardial fat thickness with transthoracic echocardiography. PATIENTS AND METHODS: PCOS patients were divided into two groups according to the lean or obesity status: PCOS patients with lean 34 subjects (BMI: 23.3±2.8; mean age: 25.5±4), PCOS patients with obese16 subjects (BMI: 32.3±7.6; mean age: 27.2±3.7) were compared with control healthy lean subjects (BMI: 23.5±1.7; mean age: 25.9±2.2). RESULTS: There was increased epicardial thickness in obese PCOS subjects compared to lean PCOS subjects (6.3±0.9 mm, 4.7±0.5, respectively, p < 0.001). However, epicardial fat thickness between lean PCOS subjects and lean healthy control groups were not significantly varied (4.7±0.5 mm, 4.5±0.5, respectively, p = 0.6). There was increased epicardial thickness in obese PCOS subjects compared to lean healthy control subjects (6.3±0.9 mm, 4.5±0.5, respectively, p < 0.001). This sudy showed for the first time that increased epicardial fat thickness measured using transthoracic echocardiography is associated with increased BMI in PCOS subjects. CONCLUSIONS: Epicardial fat thickness between lean PCOS subjects and lean healty control group were similar which indicate the importance of obesity in PCOS subjects.

A rare cause of syncope: cough.

BACKGROUND: Syncope is a transient loss of consciousness, associated with loss of postural tone, with spontaneous return to baseline neurologic function. Syncope is a common complaint in the emergency department. OBJECTIVES: Cough syncope occurs immediately after coughing. Cough syncope rapidly recovers in 1-2 second. Although cough syncope has been classified in vasovagal syncope, it may differ from pathogenetic mechanism. Physicians should be aware of this easily recognizable cough induced syncope. CASE REPORT: We present a 59-year-old obese man was referred for clinical evaluation because of recurrent syncope without seizures following coughing who developed cough syncope. CONCLUSIONS: Physicians should be aware of this easily recognizable cough induced syncope in all subjects admitted with syncope and should screen possible underlying sources of cough.
