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.

With the development of antenatal diagnostic tools such as ultrasonography, some congenital anomalies or diseases can be detected in early fetal life. Routine serial antenatal check-ups have made it possible to predict the prognosis of these problems, and a few life-threatening single anatomic malformations have been treated by open fetal surgery. The experience of fetal surgery revealed that the human fetus appears to heal without any scarring. In contrast to adult animals, the response to tissue injury in the fetus is conspiciously devoid of acute inflammation. Indeed, the absence of neutrophils is perhaps the most consistent observation in fetal wounds and seems to be followed by absent or scanty fibroblast infiltration, which results in healing with sparse and well organized collagen deposition. Actually, the amount and quality of the collagen deposition were decided by the fibroblasts which infiltrated the wound. It is well known that fetal wounds have sparse collagen deposition, however, the mechanisms are still unclear. This study was designed to evaluate the role of fibroblast activity in the differences of the scar formation between the fetus and neonate. Fibroblast activity such as the cell growth rate, the amount of collagen synthesis and the synthesized collagen types of fetus(IUP 18-22 weeks) was compared with that of neonate. The amount of collagen synthesis was measured by H-proline uptake and the amount of collagen type III was measured by Western blot using antihuman procollagen type III. The cell growth rate as determined by cell proliferation from the initial cell count of 5x10(5) to cell confluence was 3.6 x 10(6) in the fetal fibroblasts compared to 2.5x10(6) in neonatal fibroblasts. Fetal fibroblast synthesize 16.9 x 10(4) cpm of collagen and neonatal fibroblasts synthesize 2.7 x 10(4) cpm of collagen. The synthesized amount of type III collagen was 2.1x10(4) ug/ml, and 1.5x10(4) ug/ml by fetal and neonatal fibroblasts, respectively. In conclusion, fetal fibroblasts grow faster and synthesize a smaller amount of collagen, but produce more type III collagen than neonatal fibroblasts.

OBJECTIVE: The authors reviewed experience with patients harboring intracerebral hematoma (ICH) treated by stereotactic computed tomography (CT) guided thrombolysis and aspiration and evaluated feasibility, safety and prognostic factors of this procedure. METHODS: One hundred and ten patients with supratentorial ICH >25 ml without underlying structural etiology or coagulopathy were recruited. The patients with Glasgow Coma Scale (GCS) <5 were excluded. A catheter was directed stereotactically into the ICH under CT guidance. Hematoma aspiration was followed by instillation of urokinase. This was repeated every 6 hours until less than half of its initial volume remained. For analysis of prognostic factors, we classified them into two groups;good (Glasgow Outcome Scale (GOS) > or =4) and bad (GOS<4) prognosis group, and performed comparative analysis between two groups. RESULTS: Mean age was 59.8 years. The baseline hematoma size ranged from 15 to 72 mL. ICH volume reduced by an average of 74.2%. At 6 months after the procedure, 56 patients had achieved a good recovery, 29 patients were dependent, and 10 remained vegetative. Fifteen patients died in hospital. The main good prognostic factors were young age, small ICH volume, high GCS, absence of rebleeding, underlying disease and complications. CONCLUSION: CT-guided thrombolysis and aspiration appears safe and effective in the reduction of ICH volume. Patients of ICH presenting with bad prognostic factors should require frequent radiological investigation and more meticulous procedure. Further studies are needed to assess optimal thrombolytic dosage and must include controlled comparisons of mortality, and disability outcome.

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.
