Clinicopathological characteristics and treatment outcomes of adult patients with paratesticular rhabdomyosarcoma (PRMS): A 10-year single-centre experience

Introduction:

We report our experience with 8 consecutive adults treated for paratesticular rhabdomyosarcoma (RMS) at a single institution between 2000 and 2010.

Methods:

After primary surgical excision, 7 patients were classified into group I according to the Intergroup Rhabdomyosarcoma Study Group (IRSG) Postsurgical Grouping Classification, and 1 patient into group IIB. Retroperitoneal node dissection was not a required staging procedure. Adjuvant chemotherapy was administered to 7 of the 8 patients. No additional radiotherapy was administered.

Results:

The median age at diagnosis was 24 years (range: 18–60). Embryonal histology was the most common (75%) subtype. During follow-up, 3 patients experienced local relapse and 5 distant relapse. The median progression-free and overall survival times were 17.0 ± 9.9 months (range: 5–31) and 27.3 ± 1.3 months (range: 16–58), respectively.

Conclusion:

Paratesticular RMS is an uncommon malignancy in adults. We confirm that patients with localized paratesticular RMS may have different prognoses. Retroperitoneal lymphadenectomy can be avoided as a treatment for paratesticular RMS after radical inguinal orchiectomy.     

Metastases of renal cell carcinoma to the larynx and thyroid: Two case reports on metastasis developing years after nephrectomy

Renal cell carcinoma (RCC) has a high metastatic potential due to its hematogen and vascular features. It metastasizes frequently to the lungs, the bones, the liver, the lymph nodes and the brain. Metastasis of RCC to the head and neck region is quite rare. In this case report, two RCC patients with head and neck metastases are presented: one occurring after 5 years and the other occurring 17 years after diagnosis.     

Evaluation of inflammatory parameters in patients with cutaneous leishmaniasis

Cutaneous leishmaniasis (CL) is a vector‐borne parasitic disease characterized by various skin lesions that can cause deformities when healed. Our aim in this study is to show the utility of parameters such as neutrophil/lymphocyte ratio (NLR), thrombocyte/lymphocyte ratio (TLR), and mean thrombocyte volume (MTV) as auxiliary laboratory methods in CL patients. About 107 patients who were admitted to our dermatological and venereal diseases outpatient clinic between January 2018 and January 2019 and were diagnosed with CL by microscopic examination and 74 healthy individuals were included in the study. There were no significant differences between the patient and control group in terms of neutrophil counts, leukocyte counts, platelet counts, and NLR values (P values: .271, .053, .263, and .459, respectively). When the TLR and MTV values of patients with CL and those of the healthy controls were compared, it was found that TLR and MTV values were statistically higher in patients with CL (P values of .010 and .044, respectively). Based on these data, NLR was not considered to be a suitable parameter for demonstrating inflammation in CL patients, but TLR and MTV were held to be an appropriate parameter for demonstrating inflammation in CL patients. In addition, we think that the increase in MTV and TLR, can be used as an auxiliary laboratory test in the diagnosis of CL disease.

Effects of curcumin on proinflammatory cytokines and tissue injury in the early and late phases of experimental acute pancreatitis

Background & aimsAcute pancreatitis (AP) varies from mild to severe necrotizing changes with high mortality. The objective of the current study was to investigate the effects of curcumin on tissue injury and proinflammatory cytokines in the early and late phases of AP.MethodsAP was induced by sodium taurocholate in rats (n = 140). First group was left untreated. Group II received 100 mg/kg curcumin daily starting 20 days before AP induction. The rats were allocated into 7 sub-groups (n:5) and were sacrificed at 2, 6, 12, 24, 72, 144 and 288 h following the induction of AP. Blood and pancreatic tissue samples were collected for biochemical and histopathologic evaluations and the assessment of protein and mRNA levels, as well.ResultsCurcumin decreased total histopathologic scores in comparison with those of the taurocholate group (P < 0.05). Curcumin increased Caspase-3 activity and decreased trypsin activity, while inhibited nuclear factor-κ (NF-κB) at all time points (P < 0.05) and moreover reduced activator protein-1 (AP-1). Curcumin decreased chemokine (except for 288 h), TNF-α (except for 2 and 24 h), IL-6 (except for 2, 6 and 288 h) and iNOS (except for 144 and 288 h) mRNA levels (P < 0.05). Curcumin serum nitric oxide (NO) (except for 144 and 288 h) levels were reduced, as well.ConclusionsIn conclusion, curcumin reduced tissue injury, trypsin activation and inhibited NF-κB and AP-1. However TNF-α, IL-6 and iNOS and NO were not inhibited at all time points. Therefore no direct correlation was detected in the subgroups between tissue injury, proinflammatory cytokines and oxidative enzymes.     

Thrombus Entrapment in the Hemostasis Valve during Thrombus Aspiration: An Octogenarian with Inferior Myocardial Infarction and Complete Flow Restoration without Any Additional Angioplasty

Published reports demonstrate improved myocardial reperfusion with adjunctive thrombus aspiration in ST-elevation myocardial infarction (STEMI). However, implementation of this procedure without angioplasty or stent implantation is not clear. In this report, we present an octogenarian with inferior STEMI who was treated with thrombus aspiration alone. Another important feature of our case is trapped thrombus material in the guiding catheter during thrombus aspiration. Operators should avoid thrombus re-injection by controlling the system carefully during aspiration procedure.
