Malignant melanoma of the stomach presenting in a woman: a case report

<p>Abstract</p> <p>Introduction</p> <p>Malignant melanoma is reported to metastasize to all organs of the human body. Although it is common for it to metastasize to the gastrointestinal tract, a melanoma located primarily in the gastric mucosa is an uncommon tumor. Gastrointestinal metastases are rarely diagnosed before death with radiological and endoscopic techniques.</p> <p>Case presentation</p> <p>In this case report the clinical course and treatment of a woman with melanoma of the stomach, without any other detectable primary lesion, is presented and discussed. A 55-year-old Turkish woman presented to our clinic with complaints of muscle pain and bone pain in the left side of her chest. During an upper gastrointestinal system endoscopy, dark cherry-colored, light elevated, round-shaped lesions were taken from her gastric fundus and from the first part of her duodenum. Biopsies from these samples were determined to be malignant melanoma by the pathologist.</p> <p>Conclusion</p> <p>Metastatic malignant melanoma cases should be examined through endoscopy for gastrointestinal metastases.</p

Survival outcomes of patients diagnosed with muscle-invasive bladder cancer who showed a response after neoadjuvant chemotherapy and refused radical cystectomy, and patients who had radical cystectomy or received chemoradiotherapy

Introduction. We aimed to compare the survival results of patients with muscle-invasive bladder cancer who responded after neoadjuvant chemotherapy (NAC) and did not accept further treatment and those who underwent radical cystectomy or received chemoradiotherapy (CRT).  Material and methods. The study included 53 patients with non-metastatic muscle-invasive bladder cancer who received NAC between 2009 and 2020. Clinical findings and post-NAC survival analysis were evaluated. Survival analyses of patients who underwent radical cystectomy (RC) after NAC, received CRT, and refused treatment were compared.  Results. The median age at diagnosis was 61 (33–80) years. After NAC, 18 patients (34%) received CRT, 9 patients (17%) underwent RC, and 18 patients (34%) refused further treatment. Complete response (CR) was present in 10 (18.4%) patients, partial response (PR) in 35 (66%) patients, stable disease (SD) in 1 (1.9%) patient, and progression in 7 (13.2%) patients. Median overall survival (OS) was 78 months. Median OS was not reached in the RC arm; it was 97 months in the CRT arm and 78 months in the declined-treatment arm. There was no statistical difference between the arms (p = 0.94). Median disease-free survival (DFS) was 32 months. Median DFS in the RC arm was 30 months, in the CRT arm — 34 months, and 28 months in the declined-treatment arm after NAC. There was no statistically significant difference between the arms (p = 0.74).  Conclusions. We did not find any difference in terms of OS and DFS between patients who after NAC underwent RC, CRT, or refused treatment

Local Anesthetic Infiltration During Pediatric Percutaneous Nephrolithotomy Improves Postoperative Analgesia

Objective: Percutaneous nephrolithotomy is not pain-free due to the procedure itself and presence of post-operative diversion. Our purpose was to evaluate the efficacy of local anesthetic infiltration in postoperative analgesia in children who undergo percutaneous nephrolithotomy. Materials and Methods: Forty-two renal units were included to our study. Local anesthesia group received prilocaine and bupivacaine injection through the percutaneous access line where patients received no local anesthetic constituted the control group. All patients received the same anesthesia protocol and 15 mg/kg paracetamol infusion postoperatively four times a day. Post-operative pain scores of patients were evaluated by using FLACC-FPS scales. Patients with pain scores >= 4 received meperidine 1 mg/kg as rescue analgesic. Results: Between the two groups there was no significant difference in pain scores except 24th hour, where the local anesthesia group found to be favorable. The need (p=0.040) and total number (p=0.018) of rescue analgesic was significantly less in local anesthesia group. According to need for repetitive analgesic dose, the local anesthesia group was founded to be more advantageous (p=0.017). The postoperative analgesic satisfaction of parents' was favorable in local anesthesia group (p=0.002). Conclusion: In pediatric percutaneous nephrolithotomy, preemptive local anesthetic infiltration reduces postoperative pain, the need for analgesics, the number of analgesics used and also improves patient comfort and analgesic satisfaction.Wo
