A 7-year-old girl presented with subcutaneous emphysema, pneumomediastinum (PM), pneumoretroperitoneum, and pneumothorax caused by Mycoplasma pneumoniae (MP). The patient had been treated with clarithromycin for pneumonia at another hospital; however, her condition deteriorated and complications developed. Soon after admission to our hospital, we started the patient on minocycline and prednisolone, and the complications improved promptly. Laboratory data showed serum ferritin and urinary beta-2-microglobulin levels were greatly elevated. We therefore speculated that the patient might have underlying hypercytokinemia. Prednisolone is an effective treatment for hypercytokinemia. We therefore recommend prednisolone treatment for cases of severe M. pneumoniae pneumonia that do not respond to antimicrobial agents.

We herein report the case of a Japanese man with polyarteritis nodosa (PAN) accompanied by multiple myeloma (MM). The patient was diagnosed with PAN. Concurrently, IgG kappa paraprotein was detected, and bone marrow changes indicative of MM were observed. Prednisolone (PSL) administered at a dose of 30 mg/day was initiated; however, the serum creatinine level increased. In spite of increasing the dose of PSL to 45 mg/day and initiating treatment with double filtration plasmapheresis, the patient's renal dysfunction continued to progress and haemodialysis was introduced. He died from pneumonia 12 months after admission. We conclude that renal failure is an important risk factor in the prognosis of PAN accompanied by MM.

A 76-year-old woman suffering from granulomatosis with polyangitis (GPA) developed organizing pneumonia with positive antineutrophil cytoplasmic antibodies and microscopic hematuria. Prednisolone improved the hematuria and radiological findings; however, after tapering the dose of prednisolone, a posterior left atrial wall mass was detected in association with a fever. Both regressed spontaneously, although secretory otitis media and sinusitis were noted; the resected sinusitis specimen exhibited vasculitis highly suggestive of GPA. The clinical picture of GPA with multi-organ involvement can vary. Recognizing the various manifestations of GPA is therefore necessary in order to provide an appropriate diagnosis and disease management.

The current study presents a case of persistent hypoglycemia as the initial manifestation of advanced hepatocellular carcinoma (HCC), as well as a systematic review of the management of hypoglycemia associated with HCC. A 42-year-old female presented with loss of consciousness and a blood glucose level of 30 mg/dl (normal range, 80-140 mg/dl). Abdominal ultrasound and computed tomography were performed to investigate tenderness in the right upper quadrant, and the results revealed a hepatic mass of 15 cm in diameter, with metastasis. A diagnosis of insulinoma was ruled out by examining the insulin level. Prednisolone treatment was ineffective for relieving the persistent hypoglycemia, however, a single dose of palliative radiotherapy reduced the hypoglycemic episodes to once monthly. Due to the advanced disease, the patient refused further treatment, with the exception of a palliative therapy with glucose fluid. The patient succumbed to pneumonia with sepsis. A systematic review of the literature indicated that steroids were the most commonly used drug for hypoglycemia associated with HCC, however, in the majority of cases no effect was noted as observed in this study. Cytoreduction by surgery or systemic chemotherapy has been the most effective treatment. Although rare, hypoglycemia may be the initial symptom of HCC. Cytoreduction is the most effective method of treating hypoglycemia associated with HCC.

Nivolumab is a recently approved medication for the treatment of unresectable malignant melanoma. Many immune-related adverse events (irAEs) associated with nivolumab have been reported, such as pneumonitis, hepatitis, dermatitis, and thyroiditis. Prednisolone can effectively treat irAEs. However, it is unclear how or if nivolumab should be administered to patients after they have experienced an irAE. Herein, we show 2 patients who underwent pneumonitis as irAE. Case 1 demonstrated a cryptogenic organizing pneumonia pattern in the CT scan and case 2 had a diffuse alveolar damage (DAD) pattern. Oral corticosteroids improved chest shadow of CT scan in both cases. However, when nivolumab was re-administrated, case 1 demonstrated no symptoms, but case 2 demonstrated pneumonia again. From our cases, it is difficult to re-administrate nivolumab for the patients with pneumonitis which shows a DAD pattern in CT, even if oral corticosteroids improve their symptoms.

Lipoid pneumonia is an uncommon noninfectious inflammatory lung disease characterized by lipid deposition in the alveoli, and its etiology and treatment have not been elucidated. We report the case of a 32-year-old woman who developed lipoid pneumonia 9 months after allogeneic hematopoietic stem cell transplant for chronic myelogenous leukemia in lymphoid blast crisis. She complained of progressive cough and dyspnea shortly after discontinuation of immunosuppressive therapy given for graft-vs-host disease. Computed tomography demonstrated diffuse ground-glass opacities in the lungs, and pulmonary function test revealed restrictive impairment. Bronchoalveolar lavage fluid showed milky appearance, and transbronchial lung biopsy specimen revealed foamy macrophages infiltrating the alveoli. Based on these findings, she was diagnosed as having lipoid pneumonia. Prednisolone (1 mg/kg/d) promptly improved the symptoms, pulmonary shadows, and pulmonary function. The findings and clinical course of this case suggest that lipoid pneumonia should be recognized as one of the pulmonary complications of allogeneic hematopoietic stem cell transplantation.
