ABSTRACT

Sweet’s syndrome (SS) is an autoimmune-mediated acute febrile neutrophilic dermatosis with a number of possible etiologies, including infection, malignancy, and drug reactions. In contrast to its original description, it can rarely involve extracutaneous organs, including the central nervous system, cardiovascular system, lung, liver, gastrointestinal tract, spleen, and bone. To our knowledge, there have been only three cases of SS accompanied by acute kidney injury worldwide, and this is the first report in which the patient recovered completely from acute kidney injury as well as cutaneous lesions with early steroid administration. Here, we report a case of SS with acute kidney injury in a patient with myelodysplastic syndrome (MDS) whose skin lesions and renal function recovered fully with early diagnosis and steroid therapy along with a review of the relevant literature.

ABSTRACT

Mixed connective tissue disease (MCTD) is a rheumatologic disorder that has combined features of systemic lupus erythematosus, systemic sclerosis, and rheumatoid arthritis with the anti-U1 ribonucleoprotein (RNP) antibody. Although renal involvement is not included in any of the diagnostic criteria, it has been observed in 20% of MCTD patients. The most common renal disease is immune complex nephropathy, histologically classified as membranous glomerulonephritis, but minimal change disease (MCD) is very rare and has only been reported once previously. A previously healthy 33-year-old woman presented with generalized edema, puffy hands, arthralgia, and Raynaud’s phenomenon. We diagnosed MCD with proteinuria (> 9 g/day) and hypoalbuminemia (< 1.0 g/dL) by renal biopsy, and MCTD with a simultaneously high titer of the anti-U1 RNP antibody. The patient was treated with 200 mg/day cyclosporine and 30 mg/day prednisolone. The proteinuria and hypoalbuminemia normalized 2 months later. We report a patient with severe MCD associated with MCTD.

ABSTRACT

BACKGROUND: Previous studies have recommended a 2- to 5-year waiting time prior to kidney transplantation (KT) in patients with end-stage renal disease (ESRD) and symptomatic renal cell carcinoma (RCC) and no delay for incidental early-stage RCC. Data on Asian KT recipients are unavailable.METHODS: This is a Korean single-center retrospective study on 35 KT recipients with ESRD and RCC. Patients were classified into two groups: early KT (KT performed within 1 year after nephrectomy for RCC, including KT with simultaneous nephrectomy) and delayed KT (KT performed over than 1 year after nephrectomy for RCC). Patient survival, graft survival, and cancer recurrence were compared between both groups.RESULTS: There were no statistically significant differences in patient survival (P = 0.388), graft survival (P = 0.317), or graft rejection rate (P = 0.207) between the early and delayed KT groups. Additionally, there were no differences in pathological characteristics or RCC stage other than cancer histology: acquired cystic disease-associated RCC (47.4%) was the most common RCC type in the early KT group, whereas clear cell type (62.5%) was the most common RCC type in the delayed KT group. No RCC recurrence was observed.CONCLUSION: Patients with early-stage and asymptomatic RCC do not require a mandatory observational period prior to KT after curative nephrectomy

ABSTRACT

PURPOSE: The prognosis of human epidermal growth factor receptor 2 (HER2)-positive breast cancer has markedly improved since the introduction of trastuzumab. We aimed to evaluate the association between stromal tumor-infiltrating lymphocyte (sTIL) or FcrR polymorphisms and survival among patients with metastatic HER2-positive breast cancer who were treated with trastuzumab. METHODS: A total of 56 women with recurrent or metastatic HER2-positive breast cancer who received the trastuzumab-taxane combination as first-line treatment were included in this retrospective analysis. The single-step multiplex allele-specific real-time polymerase chain reaction technique was employed for FcrR3A genotyping. sTILs were identified via immunohistochemical analysis of surgical (n=34, 60.7%) or biopsy specimens of metastatic lesions (n=22, 39.3%). RESULTS: We classified patients based on the sTIL level (≤10% [n=44] or >10% [n=12]); high sTIL counts were more commonly observed in patients with hormone receptor-negative tumors than in those with hormone receptor-positive tumors (34.8% vs. 12.1%, p=0.02). There was a significant association between high sTIL levels and longer progression-free survival in comparison to low sTIL levels (median, 28.4 months vs. 16.8 months; p=0.03). With regard to the FcrR3A-158 genotype, patients were classified into the Phenylalanine/Phenylalanine group (23 patients, 41.1%), Phenylalanine/Valine group (23 patients, 41,1%), or Valine/Valine group (10 patients, 17.9%); these classifications were not associated with clinical outcomes. CONCLUSION: High sTIL expression may be associated with better efficacy of trastuzumab-containing therapy in patients with metastatic HER2-positive breast cancer. However, this finding warrants further evaluation in the larger population.

ABSTRACT

Invasive aspergillosis (IA) is one of the most common life-threatening complications in immunocompromised patients. Voriconazole is currently the drug of choice for IA treatment. However, some patients with IA suffer clinical deterioration despite voriconazole therapy. Management of voriconazole-refractory IA remains challenging; no useful recommendations have yet been made. Voriconazole-refractory IA can be further categorized as disease attributable to misdiagnosis or co-infection with another mold; inadequate blood voriconazole blood; inadequate tissue drug concentrations attributable to angioinvasion; immune reconstitution inflammatory syndrome; or infection with voriconazole-resistant Aspergillus. Hence, when encountering a case of voriconazole-refractory IA, it is necessary to schedule sequential tests to decide whether medical treatment or surgical intervention is appropriate; to adjust the voriconazole dose via drug monitoring; to seek CYp2c19 polymorphisms; to monitor serum galactomannan levels; and to examine the drug susceptibility of the causative Aspergillus species.

ABSTRACT

A 65-year-old female visited the emergency room for severe back pain radiating to the neck. Aortic dissection computed tomography revealed a ruptured liver abscess and large pneumoperitoneum. Although emergent percutaneous drainage of the liver abscess and aggressive resuscitation were performed, massive hemolytic anemia and disseminated intravascular hemolysis developed and she subsequently died, 11 hours after her visit to the emergency room. Clostridium perfringens was identified in a blood culture obtained at the emergency room. We report this case because refractory septic shock due to a liver abscess and massive intravascular hemolytic anemia caused by Clostridium perfringens in a healthy female is rare.

ABSTRACT

Hemophagocytic lymphohistiocytosis (HLH), associated with acute myelocytic leukemia (AML), is a very rare disease. We here report a case of HLH occurring after induction chemotherapy for AML. AML-associated HLH can be triggered by AML itself, by chemotherapeutic agents, or by infectious complications. Our patient developed a high-grade fever of unknown cause, bilateral pulmonary infiltrates, and shock after successful treatment of AML with induction chemotherapy, and had high serum ferritin, hypertriglyceridemia, hypofibrinogenemia, hemophagocytic histiocytes in bone marrow, low natural killer cell activity, and elevated soluble interleukin-2 receptor levels. A diagnosis of HLH was made. Dexamethasone, cyclosporine, and etoposide were given and allogeneic hematopoietic stem cell transplantation was performed. Careful suspicion of HLH may be warranted if a patient experiences fever of unknown etiology, high ferritin levels, and liver dysfunction during AML treatment.

ABSTRACT

PURPOSE: The purpose of this study was to analyze the effects of a cognitive-behavioral nursing intervention on anxiety and depression of patients with breast cancer undergoing radiotherapy. METHODS: A nonequivalent control group design was used for the study. The research participants were patients with breast cancer (N=71; experimental group=35, comparison group=36) who received radiotherapy at P university hospital. The experimental group received a 6-week cognitive-behavioral nursing intervention (2 hr/week), which included nursing counseling, education about treatment choices for breast cancer and possible side effects and management strategies during radiotherapy, and rehabilitation exercise. RESULTS: Following the intervention, the experimental group showed significantly lower levels of anxiety (Experimental group=34.60+/-6.35, Comparison group=44.63+/-9.93, t=3.552, p<.001) and depression (Experimental group=10.20+/-6.61, Comparison group=17.81+/-10.85, t=3.542, p<.001) than the comparison group. CONCLUSION: The findings from this study showed that cognitive-behavioral counseling applied by nurses is very effective to reduce anxiety and depression among patients with breast cancer. Therefore, providing nursing counseling to broader spectrum of patients with cancer should be considered. Further research would warrant future clinical application of nursing counseling.
