Objective In myotonic dystrophy type 1 (DM1), the CTG repeat size in the dystrophia myotonica protein kinase gene has been shown to correlate with disease severity and is a potential predictive marker for respiratory decline. However, genetic testing can be challenging in some clinical situations. We developed a simple formula for estimating the CTG repeat size using a single spirometry test in patients with DM1. ⋯ The derived formula [repeat size=-16.8× (age+%VC/0.90) +2663] had a moderate predictive performance with a mean coefficient of determination
of 0.41. Conclusion The CTG repeat size in patients with DM1 can be potentially predicted using a simple formula based on a single spirometry test conducted at any time over the disease course. It can be useful as a supportive tool for advance care planning when genetic testing is not available.

Review Case Reports
Adrenal Schwannoma in an Elderly Man: A Case Report and Literature Review.
Schwannoma is a common mesenchymal neoplasm; however, adrenal schwannoma is rare, and it is frequently misdiagnosed as adrenal cortical adenoma. We herein report a 91-year-old Japanese man with right adrenal schwannoma that was pathologically diagnosed after adrenalectomy. To our knowledge, this is the first case of adrenal schwannoma in the oldest patient and with the longest follow-up period reported, including radiological images from 10 years earlier.

The retention of the capsule used during small bowel capsule endoscopy (SBCE) is a serious complication that can occur in patients with known or suspected small bowel stenosis, and a prior evaluation of the patency of the gastrointestinal (GI) tract is therefore essential. Patency capsule (PC) is a non-diagnostic capsule the same size as the diagnostic SBCE. ⋯ In this review, we summarize the indications and limitations of PC prior to SBCE, especially the contraindications, and discuss clinical scenarios in which even PC should be avoided, and therefore such areas of stenosis should be evaluated by alternative modalities. We thus propose this new algorithm to evaluate the patency of the GI tract for patients with suspected and known small bowel stenosis in order that they may undergo SBCE safely.

This review summarizes the adverse effects of Kampo medicines. These adverse effects in terms of immunoallergic reactions include interstitial pneumonia, liver injury, allergic cystitis, and drug eruption. ⋯ In recent years, mesenteric phlebosclerosis caused by the long-term administration of Gardeniae Fructus (gardenia fruit, sanshishi) has also been reported. It is necessary to consider these potential adverse effects when prescribing Kampo medicines in clinical practice.

Multicenter Study
Factors Contributing to the Prognosis after Second-line Therapy with Ramucirumab in Advanced Hepatocellular Carcinoma.
Objective Multiple therapeutic agents exist for advanced hepatocellular carcinoma (HCC), but prognostic factors in second-line and subsequent therapies are unclear. Ramucirumab is a molecular-targeted agent effective against hepatocytes with alpha-fetoprotein (AFP) >400 ng/mL after sorafenib failure. We examined the prognostic factors and efficacy of ramucirumab with prior therapy other than sorafenib. ⋯ A good ALBI value at initiation and ALBI value improvement during treatment were also identified as independent factors associated with eligibility for further treatment after ramucirumab failure. The treatment line did not correlate with the availability of treatment with another drug after treatment failure. Conclusions ALBI value improvement with ramucirumab treatment allows for subsequent treatment after failure and an improved overall prognosis.
