Acute Tubulointerstitial Nephritis due to Human Papillomavirus Vaccination.

Acute tubulointerstitial nephritis (ATIN), a rare cause of acute kidney injury in children, is caused by various factors such as drugs, infection, and systemic inflammation. We herein present a case of ATIN with mild encephalitis/encephalopathy with reversible splenial lesion (MERS)-like findings on head magnetic resonance imaging (MRI), which was associated with human papillomavirus (HPV) vaccination. A 14-year-old girl presented to our hospital with a high fever for 5 days. Results of common laboratory tests were normal except for increased C-reactive protein (CRP) levels and erythrocyte sedimentation rate (ESR). Antibiotics were administered, and the fever promptly resolved after admission. After 7 weeks, she was readmitted due to a high fever for 4 days. In addition to increased CRP levels and ESR, urine test revealed high urine N-acetyl-ß-D-glucosaminidase and ß-2-microglobulin levels, and a renal scintigram showed mild bilateral uptake of 67Ga-citrate, consistent with the pathology of ATIN. Furthermore, head MRI, which was performed because the patient experienced prolonged headaches, revealed MERS-like lesions, although she did not have other neurological symptoms. Detailed examination of her medical records revealed that she had developed high fever 10 days after the third HPV vaccination and another previous episode of high fever 12 weeks after the second HPV vaccination. Based on these findings, we concluded that the ATIN and MERS-like lesions could have been associated with HPV vaccination. Although HPV vaccination is important for preventing uterine cancer, physicians must be vigilant about its various potential adverse effects, including ATIN.

Trends in descriptions of palliative care in the cancer clinical practice guidelines before and after enactment of the Cancer Control Act (2007): content analysis.

BACKGROUND: Palliative care was a priority issue in the Cancer Control Act enacted in 2007 in Japan, and this has resulted in efforts being made toward educational goals in clinical settings. An investigation of how descriptions of palliative care for the treatment of cancer have changed in clinical practice guidelines (CPGs) could be expected to provide a better understanding of palliative care-related decision-making. This study aimed to identify trends in descriptions of palliative care in cancer CPGs in Japan before and after enactment of the Cancer Control Act. METHODS: Content analysis was used to count the lines in all relevant CPGs. We then compared the number of lines and the proportion of descriptions mentioning palliative care at two time points: the first survey (selection period: February to June 2007) and the second survey (selection period: February to December 2015). Descriptions from the CPGs were independently selected from the Toho University Medical Media Center and Medical Information Network Distribution Service databases, and subsequently reviewed, by two investigators. RESULTS: Descriptions were analyzed for 10 types of cancer. The proportion of descriptions in the first survey (4.4%; 933/21,344 lines) was similar to that in the second survey (4.5%; 1325/29,269 lines). CONCLUSIONS: After the enactment of the Cancer Control Act, an increase was observed in the number, but not in the proportion, of palliative care descriptions in Japanese cancer CPGs. In the future, CPGs can be expected to play a major role in helping cancer patients to incorporate palliative care more smoothly.

A de novo interstitial deletion of 8p11.2 including ANK1 identified in a patient with spherocytosis, psychomotor developmental delay, and distinctive facial features.

The contiguous gene syndrome involving 8p11.2 is recognized as a combined phenotype of both Kallmann syndrome and hereditary spherocytosis, because the genes responsible for these 2 clinical entities, the fibroblast growth factor receptor 1 (FGFR1) and ankyrin 1 (ANK1) genes, respectively, are located in this region within a distance of 3.2Mb. We identified a 3.7Mb deletion of 8p11.2 in a 19-month-old female patient with hereditary spherocytosis. The identified deletion included ANK1, but not FGFR1, which is consistent with the absence of any phenotype or laboratory findings of Kallmann syndrome. Compared with the previous studies, the deletion identified in this study was located on the proximal end of 8p, indicating a pure interstitial deletion of 8p11.21. This patient exhibited mild developmental delay and distinctive facial findings in addition to hereditary spherocytosis. Thus, some of the genes included in the deleted region would be related to these symptoms.
