PUTH Grading System for Urinary Tumor With Supradiaphragmatic Tumor Thrombus: Different Surgical Techniques for Different Tumor Characteristics

PurposeTo explore the different treatment strategies for urinary tumors with Mayo IV thrombus.Materials and MethodsWe retrospectively analyzed the patients with Mayo IV thrombus in Peking University Third Hospital from January 2014 to April 2021. We used the Peking University Third Hospital (PUTH) grading system to classify urinary tumors with supradiaphragmatic thrombus. PUTH-A referred to the filled thrombus whose tip just reached above the diaphragm, or the thrombus entering the right atrium (< 2cm). PUTH-B referred to the filled thrombus entering the right atrium (> 2cm), or the thrombus invading the wall of the inferior pericardial vena cava. Detailed techniques were described for various scenarios. Clinicopathological data and perioperative outcomes were reported. Group difference statistical analysis was performed.ResultsA total of 26 cases of urinary tumors with supradiaphragmatic IVC thrombus (Mayo grade IV) underwent treatment were enrolled in this study. 19 patients in the PUTH-A group received the open approach without sternotomy and cardiopulmonary bypass. Seven patients in the PUTH-B group received open thoracotomy assisted by cardiopulmonary bypass. No intraoperative death occurred. After 56 months of follow-up, 46.2% (12 of 26) patients died of all causes. Estimated 1-year, 2-year, and 3-year overall survival were 72.0% (95% CI, 54.4%-89.6%), 58.2% (95% CI, 38.0%-78.4%), and 52.4% (95% CI, 31.2%-73.6%), respectively.ConclusionsWe introduced the PUTH grading system for the characteristics of urinary tumors with supradiaphragmatic tumor thrombus, and selected different surgical techniques according to different classifications. This grading system was relatively feasible and effective.

A multi-parameter grading system for optimal fitting of scleral contact lenses

Background: While scleral lens practise has improved over the years due to factors such as availability of lenses with better materials and designs as well as experience of practitioners, a lack of objectivity appears to remain in terms of assessment of scleral lens fitting. This prospective observational work aimed to achieve standardization on this front through proposing a grading system for scleral lens fitting. Methods: After application of prosthetic replacement of ocular surface ecosystem (PROSE) devices on the participants’ eyes, four fundamental components for understanding scleral lens fitting such as central and limbal corneal clearance, mid-haptic compression, and alignment of lens edge over anterior sclera were assessed through a series of slit-lamp biomicroscopy imaging as well as with anterior segment optical coherence tomography. FitConnect® was used to modify the device parameters to simulate different grading patterns on the proposed scale. Serial imaging was done for all the different lenses to compose the grading scale. Results: A clinically relevant grading scale was constructed that pictorially demonstrated grades for the different aspect of scleral lens fitting. The grades were conveniently scaled within three categories: “optimal”, “acceptable” and “not acceptable”. Conclusion: The gradation of scleral lens fitting parameters would take a step towards objectifying the assessment patterns in practise. This will also help reducing the gap between a novice and an experienced practitioner in terms of understanding of scleral lens fitting.

A Comparative Study of Efficacy of Fractional CO2 Laser vs Microdermabrasion in Treatment of Acne Scars (Total 100 Patients)

Introduction: Acne vulgaris is a common disease affecting pilosebaceous unit that can lead to significant scarring. Fractional CO2 Laser and microdermabrasion are effective non-surgical treatment modalities for acne scars. Aims and objectives: To study and compare the efficacy of fractional CO2 Laser and microdermabrasion therapy in acne scars. Material and methods: Total 100 patients were selected in our study. 50 patients were allotted into each group. Scar grading assessment was done by Goodman and Baron qualitative scar grading system. Result: 50 patients were taken in each group. There was a significant improvement in grading of acne scars at the end of 6months of treatment. On comparison of fractional CO2 Laser with microdermabrasion, p-value was <0.05 that is significant. Conclusion: Fractional CO2 Laser showed better improvement in grading of acne scars then microdermabrasion, though none of these treatments are 100% effective in treating acne scars. Keywords: Acne scars, fractional CO2 laser, microdermabrasion, Goodman and baron grading.

IMPACT OF ACNE VULGARIS ON A PERSON’S QUALITY OF LIFE AND IT’S CORRELATION WITH THE CLINICAL SEVERITY PRE AND POST-DRUG THERAPY

Objective: The aim of the study is to assess the therapeutic efficacy of drugs used in acne vulgaris by measuring the severity of acne using the Global Acne Grading System score (GAGS) and Cardiff Acne Disability Index (CADI) questionnaire score pre and post-drug therapy. Methods: The present study was conducted in the Department of Dermatology after getting approval from the Institutional Ethics Committee (No MC/190/2007/Pt1/MAR-2019/PG/123) dated 10/04/2019. It was an observational study for a period of 1 y. 172 patients were enrolled in the study. Patients were divided into 4 grades depending on their clinical manifestation. The severity of acne vulgaris and the quality of life were measured using the GAGS scale and the CADI questionnaire, respectively at the first visit and at the follow-up visit in all the grades of acne vulgaris. A correlation was done between the GAGS and the CADI score at the follow-up visit in all grades of acne. Results: It was observed that the GAGS score and the CADI score was significantly improved at the F/U visit (p<0.05) as compared to baseline in all the 4 grades of acne. A correlation between GAGS score and QoL using CADI scale was done using Pearson Parametric Correlation Test. In none of the groups, the correlation was significant (p>0.05). Conclusion: We can conclude from our study that following treatment with drugs, the clinical severity of acne decreased and there was also a significant improvement in the quality of life of patients.

Histopathology of hepatocellular carcinoma - when and what

When do you need to take biopsies of the liver, and what information will you get is the topic of this review on hepatocellular carcinoma (HCC). If, clinically, the differential diagnosis of HCC after imaging is suggested, a biopsy has become obligatory as a diagnostic confirmation of HCC in the non-cirrhotic liver prior to definitive therapeutic interventions, as well as in a palliative therapy concept. In the case of hepatic lesions with an uncharacteristic contrast uptake, a biopsy should be performed immediately to confirm the diagnosis of HCC. After diagnosing HCC, a treatment strategy is evaluated. Further, the biopsy, or in case of surgical treatment, the resected tissue, shows us the different subtypes of HCC, with the steatohepatitic subtype being the most common and the lymphocyte-rich subtype being the least common. Further, the histological grade of HCC is determined according to the grading system of the WHO or the Edmonson and Steiner System. Through biopsies, HCC can be differentiated from intrahepatic cholangiocarcinoma or combined hepatocellular-cholangiocarcinoma or metastases of other malignant tumors, especially metastases of the gastrointestinal tract. In summary, biopsies are fundamental in the diagnosis of HCC.

Clinical Experience and Management Strategy of Retroperitoneal Tumor With Venous Tumor Thrombus Involvement

Background: To report the surgical management, complications, and outcomes for patients with retroperitoneal tumor and venous thrombus Methods: We retrospectively analyzed 19 cases of retroperitoneal tumor with venous tumor thrombus from August 2015 to March 2021. According to the characteristics of surgical techniques, a new tumor thrombus PUTH grading system was proposed. Results: There were 2 cases of PUTH-1a, 2 cases of PUTH-1b, 6 cases of PUTH-2, 6 cases of PUTH-3,3 cases of PUTH-4. All the operations were successfully performed in 19 patients. Among them, 5 cases (26.3%) were operated by completely laparoscopic approach and 13 cases (68.4%) were operated by open approach. One case (5.3%) was converted from laparoscopic approach to open approach. 5 cases experienced postoperative complications, the incidence was 26.3%. All the cases were followed-up for a median of 14 months. Cancer associated death were occurred in 3 cases. Distant metastases were occurred in 7 cases. Conclusions: In this study, we proposed a new tumor thrombus grading system based on the anatomical characteristics of retroperitoneal tumors with venous tumor thrombus. Retroperitoneal tumor resection and removal of venous tumor thrombus are safe and effective in the treatment of such diseases.
