Objective: To understand the social security situation of current cases of pneumoconiosis in non-coal mine industries in Jiangsu Province, and to provide reference for the treatment and security work of pneumoconiosis patients. Methods: From January to October 2020, a follow-up survey was conducted on 4038 cases of pneumoconiosis in non-coal mine industries of the province from October 1949 to December 2019. The age, type of pneumoconiosis, industry type, and social security status of the patients were collected. Namely, work-related injury insurance, employer compensation, basic medical insurance for urban and rural residents, major illness insurance, etc. SPSS 19.0 was used for statistical description and analysis. Results: The cases of pneumoconiosis in non-coal mine industries in Jiangsu Province ranged in age from 36 to 105 (70.78±8.43) years old, and had been exposed to dust for 1 to 55 (19.27±9.29) years. Silicosis was the main form (3875 cases, 95.96%), and non-metallic mining and dressing industry was the main form (2618 cases, 64.83%). A total of 3991 cases (98.84%) of pneumoconiosis patients enjoyed social security, most of them were urban and rural residents with basic medical insurance (3624 cases, 89.75%), but there were still 47 patients without any social security. 15 cases (0.37%) enjoyed the subsistence allowance, with the monthly allowance amount ranging from 104 to 3960 yuan, with the average amount of 954.87 yuan/month. Conclusion: In Jiangsu Province, the proportion of pneumoconiosis patients in non-coal mine industries enjoying social security is relatively high, but there are still patients who do not enjoy any social security, and the difference in the amount of subsistence allowance is slightly larger. It is necessary to further improve the medical security of pneumoconiosis patients and improve their quality of life.

BACKGROUND: This study aimed to assess the treatment outcomes of ifosphamide, mesna, etoposide, and prednisolone (IMEP) combination regimen as a front-line chemotherapy in patients with peripheral T-cell lymphomas (PTCLs). METHODS: Clinical data of 38 newly diagnosed PTCLs patients who underwent IMEP at Busan Paik Hospital from January 2002 to December 2013 were retrospectively analyzed. RESULTS: The overall response rate was 68.5%, with 21 (55.3%) complete response/complete response unconfirmed and 6 (15.8%) partial response (PR). The median follow-up duration was 25.5 months (range, 0.2-87.3). The median overall survival was not reached and 2-year survival rate was 67%. The median progression free survival was 23 months. The most frequently reported adverse effects higher than grade 3 were hematologic toxicities including neutropenia (68.4%), thrombocytopenia (42.1%). There was no treatment-related mortality. CONCLUSION: IMEP regimen is effective and safe as a front-line chemotherapy in patients with PTCLs.

Hemorrhagic cystitis is a common stem cell transplantation-related complication. The incidence of early-onset hemorrhagic cystitis, which is related to the pretransplant conditioning regimen, has decreased with the concomitant use of mesna and hyperhydration. However, late-onset hemorrhagic cystitis, which is usually caused by the BK virus, continues to develop. Although the BK virus is the most common pathogenic microorganism of poststem cell transplantation late-onset hemorrhagic cystitis, pediatricians outside the hemato-oncology and nephrology specialties tend to be unfamiliar with hemorrhagic cystitis and the BK virus. Moreover, no standard guidelines for the early diagnosis and treatment of BK virus-associated hemorrhagic cystitis after stem cell transplantation have been established. Here, we briefly introduce poststem cell transplantation BK virus-associated hemorrhagic cystitis.

OBJECTIVE: Cisplatin is a widely used chemotherapeutic agent in the treatment of cancers in clinic; but it often induces adverse effects on ovarian functions such as reduced fertility and premature menopause. Mesna could attenuate the cisplatin-induced ovarian damages; however, the underlying mechanism is still unknown. This study aimed to figure out the underlying mechanism of the protection of mesna for ovaries against cisplatin therapy in cancers. METHODS: We performed female adult Sprague-Dawley rats into normal saline control (NS), low-dose cisplatin (CL), high-dose cisplatin (CH), CL plus mesna (CL+M), and CH plus mesna (CH+M) groups and detected anti-Mullerian hormone (AMH)-positive follicle, oxidative stress status and anti-oxidative capability in ovaries. RESULTS: AMH-positive follicles were significantly decreased after cisplatin administration, which was significantly reversed when mesna was co-administered with cisplatin. The end product of lipid peroxidation, malondialdehyde (MDA), was significantly increased, but the anti-oxidative enzymatic activity of superoxide dismutase (SOD) and glutathione (GSH) were significantly decreased in cisplatin groups when compared with NS group. In contrast, after co-administration of cisplatin with mesna, MDA was significantly decreased whereas the activity of SOD and the concentration of GSH were increased. Moreover, mesna did not decrease the anti-tumor property of cisplatin in HePG2 cell lines. CONCLUSION: Cisplatin damages the granulosa cells by oxidative stress to deplete the ovarian reserve and mesna could protect ovarian reserve through anti-oxidation. These results might highlight the mechanism of the protection of mesna for ovarian reserve and open an avenue for the application of mesna as a protective additive in cisplatin chemotherapy in clinical practise.

OBJECTIVETo analyze the clinical features, treatment and prognosis of Stage IV alveolar soft part sarcoma.

METHODSTo analyze the clinical and pathological features, therapeutic methods and follow-up results in 21 patients with stage IV alveolar soft part sarcoma. There were 11 males and 10 females, in the age of 26-57 years (average 37.0 years old). All the 21 patients had metastasis: nine cases had multiple pulmonary metastasis, three cases had multiple pulmonary and brain metastasis, two cases had multiple brain metastasis, two cases had multiple pulmonary and bone metastasis, two cases had single pulmonary metastasis, one case had single bone metastasis, one case had single brain metastasis and one case had single soft tissue metastasis. Eight patients were treated by surgical operation, including five cases of complete resection for the primary and (or) metastatic tumor and 3 cases of palliative operation for the primary tumor. All patients received chemotherapy, including seven cases of CAVD regimen and 14 cases of MAID regimen treatment. One patient with single bone metastasis and five patients with multiple brain metastasis received post-operative whole brain radiation therapy.

RESULTSAll the eight patients with surgical operation had healing by first intention, and pathological examination showed that seven patients achieved R0 surgical margin and one case with R2 status. One patient with single brain metastasis had recurrence after operation. The toxic and adverse reactions of all patients treated with chemotherapy were tolerable. Among them, 17 cases had stable disease and 4 cases had disease progression after chemotherapy. The disease control rate (DCR) was 81.0%. The DCR of patients with CAVD regimen chemotherapy was 85.7% and that of patients treated with MAID regimen was 78.6% (P = 0.862). All patients were followed up for 8 - 86 months (average 32.4 months). The median survival time of all patients was 32.6 months. The 2-year survival rate was 55.1% and the 5-year survival rate was 21.8%. The median survival time in the patients with complete resection was 60.0 months, and that in patients with palliative operation was 27.0, showing a significant difference between them (P = 0.048). The median progression-free survival in patients with complete excision was 57.2 months and that in patients with palliative operation or without operation was 19.6 months, with a significant difference (P = 0.029). The median survival time in patients who received CAVD regimen chemotherapy was 30.0 months, and that in patients with MAID regimen was 51.0 months, with a non-significant difference (P = 0.511). The median progression-free time in patients with CAVD regimen chemotherapy was 13.0 months, and that in patients with MAID regimen was 38.0 months, also with a non-significant difference (P = 0.066).

CONCLUSIONSAlveolar soft part sarcomas are rarely seen and highly malignant tumors, and the prognosis of stage IV ASPS is poor. Complete resection of all tumors is the key of successful treatment of Stage IV ASPS, and the site and number of tumor metastasis are important factors affecting prognosis. The curative effects of radiotherapy and chemotherapy for ASPS need to be further investigated.

A fixed drug eruption (FDE) is a cutaneous reaction caused by various drugs. Mesna is used to decrease urotoxic side effect of cyclophosphamide and there have been no previously reported cases in Korea for any adverse reactions to this drug. Herein, we report a case of a FDE caused by mesna. A 34-year-old woman presented with asymptomatic, brownish macules and patches on the face and back for the past 4 months. She had been treated for SLE with monthly pulses of intravenous cyclophosphamide and mesna for 6 months. She had experienced similar episodes after injection of mesna. The skin biopsy specimen taken from her showed vacuolar degeneration of the basal cell layer and perivascular lymphohistiocyte infiltration in the papillary dermis. We performed prick test, scratch patch test, and intradermal test with mesna and confirmed that a FDE was caused by this drug.

Central nervous system (CNS) toxicity has been reported in approximately 10-30% of patients receiving intravenous infusions of ifosfamide. Encephalopathy is a rare but serious CNS adverse reaction in these patients, and although usually transient and reversible, may cause persistent neurological dysfunction or death. Clinical features range from fatigue and confusion to coma and death. Although methylene blue can be used to treat ifosfamide-induced neurotoxicity, including encephalopathy, its mechanism of action remains poorly defined. We describe here two patients with recurrent epithelial ovarian cancer who experienced fatal encephalopathy following ifosfamide/mesna treatment.

The alkylating agent ifosfamide is an anti-neoplastic used to treat various pediatric and adult malignancies. Its potential urologic toxicities include glomerulopathy, tubulopathy and hemorrhagic cystitis. This report describes a case of proximal renal tubular dysfunction and hemorrhagic cystitis in a 67-year-old male given ifosfamide for epitheloid sarcoma. He was also receiving an oral hypoglycemic agent for type 2 diabetes mellitus and had a baseline glomerular filtration rate of 51.5 mL/min/1.73 m2. Despite mesna prophylaxis, the patient experienced dysuria and gross hematuria after a single course of ifosfamide plus adriamycin. The abrupt renal impairment and serum/urine electrolyte imbalances that ensued were consistent with Fanconi's syndrome. However, normal renal function and electrolyte status were restored within 14 days, simply through supportive measures. A score of 8 by Naranjo adverse drug reaction probability scale indicated these complications were most likely treatment-related, although they developed without known predisposing factors. The currently undefined role of diabetic nephropathy in adult ifosfamide nephrotoxicity merits future investigation.

Endometrial stromal sarcoma (ESS) that arises from extrauterine endometriosis is a rare form of malignancy. We report the case of a 37-year-old ESS patient with extrauterine endometriosis who was treated with ifosfamide/cisplatin chemotherapy. A woman presented with epigastric pain and abdominal distension. Computed tomography imaging revealed a profuse amount of ascites, including a 12.4x12.3 cm sized posterior cul-de-sac mass composed of solid and cystic components. Cytoreductive surgery was performed to remove the mass and the histopathologic findings indicated ESS associated with extrauterine endometriosis. Six cycles of combination chemotherapy [ifosfamide (5 g/m(2)) with mesna (1 g/m(2)) and cisplatin (50 mg/m(2)) (IP)] were administered. After a six-month of disease-free interval, recurrent ESS developed in the pelvic cavity and in both lung fields. Megace medication decreased tumor marker CA-125 for six weeks. However, the patient expired sixteen months after the cytoreductive surgery. ESS associated with extrauterine endometriosis showed response to IP chemotherapy and megace.
