Solid pseudopapillary pancreatic neoplasms are rare. The male-to-female ratio is 1:9, and metastasis occurs only in a few cases. A 39-year-old male with a solid pseudopapillary neoplasm (SPN) with lymph node metastasis underwent ultrasonography, CT, and MRI, which revealed a mass (8 cm) in the pancreatic head. Fluorodeoxyglucose (FDG)-PET showed a hypermetabolic lymph node in the root area of the superior mesenteric artery (SMA). The patient underwent pylorus-preserving pancreaticoduodenectomy, which confirmed a peripancreatic lymph node metastasis. The lymph node of the SMA root area remained because of the encasing of the superior mesenteric artery. After 14 months of follow-up (with no adjuvant therapy initiated), the residual metastatic lymph nodes showed no change and no recurrence. In conclusion, surgery of the primary tumor for patients with SPN is recommended, even in cases with metastatic lymph nodes remaining.

An inflammatory myofibroblastic tumor (IMT) is a rare tumor that is currently classified as an intermediate cancer according to the World Health Organization classification system. The pathophysiology of its occurrence is still unknown. Imaging tests, such as CT or MRI, can be helpful in diagnosis, but the final diagnosis is confirmed by a pathological examination through a biopsy and immunohistochemistry stain. The patient, in this case, presented an asymptomatic intrahepatic mass discovered incidentally on an imaging examination. Initially, intrahepatic cholangiocarcinoma was suspected, but she was finally diagnosed with IMT through a histological examination after a liver resection.

Artificial intelligence (AI) is now very closely related to the work of internal medicine physicians. Internal medicine physicians must actively cope with and study the weak AI that affects them. Active use of weak AI can result in a reduced frequency of medical accidents and improved work efficiency. However, the form of medical consultation designed to treat patients based on behavior and guidelines of simply looking for symptoms and prescribing medications will ultimately disappear. As the age of self-care has begun, directors of local internal medicine clinics may expand their business to include AI-based chronic diseases and healthcare service companies to treat chronic diseases.

The objectives of this study sere to investigate how the local irradiation affect the survival of random pattern skin flap, and whether or not hyperbaric oxygen and allopurional can improve the survival of the irradiated rat skin flap. There have been many reports about the effects of hyperbaric oxygen and allpurinol on skin flaps. However, very few reports have been presented on the effects of hyperbaric oxygen and allpurinol in treating irradiated skin flaps. The author examined the local irradiation effect on rat skin flap survival after irradiation of 20 Gy, 3 days postoperatively, on cranially based random pattern dorsal skin flap, which was 3 x 9cm in size. The flap survival length was measured in experimental groups treated with hyperbaric oxygen (2.5 atm absolute, 100% oxygen, once a day for 7days) after irradiation and with hyperbaric oxygen combined with allopurinol (100mg/kg, once a day for 7 days), in comparison with a radiation-only group. On reviewing the flap survival length 10 days postoperati-vely, the average flap survival length in the radiation-only group was 2.2+/-0.5cm, while in the non-radiation group it was 5.5+/-0.3cm. The reduction ratio of flap survival by irradiation was 60%. There was a significant increase in the mean flap survival length in the groups treated with hyperbaric oxygen (4.0+/-1.6cm) and hyperbaric oxygen combined with allopurinol (5.5+/-1.8cm). The increased ratio of flap survival in each group was 85% and 150% when compared to the radiation-only group. The author found that rat skin flap survival decreased, even at an early stage, as a result of high dose local irradiation and that decreased flap survival by irradiation could be restored by hyperbaric oxygen and allopurinol. The group treated with hyperbaric oxygen combined with allopurinol showed increased flap survival over the group treated with hyperbaric oxygen only. The results showed a method which could possibly increase flap survival in cancer patients who require early radiation after flap surgery.

Schonlein-Henoch purpura is a generalized small vessel vasculitis characterized by nonthrombocytopenic purpura, arthritis, abdominal pain and nephritis. In 1914 Osler described an allergic purpura associated with hemiplegia. After then Lewis et al. reported the cases of Schonlein-Henoch purpura associated with convulsion, coma, confusion, intracranial hemorrhage, and chorea, CNS complication has been reported in 1-8% of children and subsided spontaneously in most cases. Headache is a remarkable sympton and appears nonspecific nature. In 1991 Ostergaard and Storm reported that headache occured during the first week following skin rash and frequently showed abnormal EEG findings. We investigated prospectively the presence of a possible cerebral and renal involvement in the case of Schonlein-Henoch purpura. EEG abnormality demonstrated in 52.6% of all cases, and headache or irritability in 47.4% of all cases. A significant association was found between abnormal EEG finding and presence of headache, but was not found between EEG findings and presence of renal involvement and hypertension. Patients with abnormal EEG had no Past or famity history of febrile convulsion or ididopathic epilepsy.
