All clinical studies reported in the literature have indicated that non-operative treatment is the treatment of choice for the diaphyseal fractures of the clavicle. It has also been suggested by some that open reduction may contribute the development of nonunion. From 1985 to 1989, 23 of 133 diaphyseal fractures of the clavicle were treated by open reduction and internal fixation with the intramedullary pinning with or without cerclage wiring, or prebent plate and screw fixation with supplementary iliac bone graft in each instance. All fractures healed without any complication such as the infection, pin migration, other fixation failure, neurovascular accident, and pseudarthrosis. Based on our experience and review of the literature, we concluded that the indications for open reduction and internal fixation should be: 1. The patient's inability to tolerate prolonged immobilization or recumbency in multiple injury. 2. Widely distracted or displaced fractures in adults. 3. Comminution with one or more large butterfly fragments. 4. Neuro-vascular compromise due to displacement and impingement of the bone fragment. 5. Symptomatic delayed union or nonunion. 6. Refracture. And early operative treatment is safe, reliable and provide excellent results comparable to the conservative treatments.

Intramedullary nailing has become the most popular fixation method in the treatment of the shaft fractures of long bones especially of tibia and femur because it affords most rigid fixation of fracture via closed method which makes early rehabilitation possible. Nowadays intramedullary nailing of the humeral shaft is being performed by many surgeons with good results. Newer implants and better surgical techniques are being developed, which suggests application of this method can be widened. Purpose of this study was aimed to define whether intramedullary nailing could be an effective method or not in the treatment of humeral shaft fractures by documenting the practical points in the application of intramedullary nailing of humerus, effectiveness in fracture healing, any complications or obstacles. We managed thirteen humeral shaft fractures with closed locked intramedullary nailing with distal fanning devices(Seidel nail) from March 1993 to April 1994. Average follow-up period was 14 months(12 months-18 months). The results were as follows; 1, Union of the fracture was obtained at average 12.9 weeks(9 weeks-20 weeks) postoperatively except one case of nonunion, in which case, union was obtained at postoperative 10 months finally. 2. Among the 13 cases, painful limitation of shoulder motion remained in 6 cases. This complication was more common in the cases with protruded proximal end of the nail. Above results suggest that locked intramedullary nailing seemed to be one of the useful method in the treatment of the humeral shaft fractures. However, destruction and irritation of shoulder by the nail was found to be a grave problem, and we found that further investigations should solve this problem.

Endoscopic papillectomy (EP) has been considered to be a less invasive, alternative therapy to surgery for ampullary adenoma. However, complication rates after EP could not be ignored, when compared to endoscopic resection for gastrointestinal lesions. Among them, the prevalence of postpapillectomy pancreatitis is higher in EP than ERCP. The prophylactic placement of a pancreatic stent has been reported to decrease the risk of pancreatitis after EP. However, since pancreatic stent placement after EP is not always successful, various novel techniques have been developed to ensure reliable stent placement. Despite the recent advances in EP, a prospective, randomized, controlled study with a larger number of patients is needed to assess the efficacy of pancreatic stent placement to prevent pancreatitis.

Papillary and solid epithelial neoplasm of the pancreas from five patients were studied using immunohistochemistry and electron microscopy to define the cellular origin of this type of tumor. The tumors ranged in diameter form 5.5 to 15 cm Grossly, these were well circumscribed by a firm, gray-white, fibrous capsule and their cut-surface showed mainly area containing mucinous substance with necrotic and hemorrhagic material, with some solid portion. Microscopically, there was a solid and papillary pattern, with uniform cells typically having round to ovoid nuclei containing indistinct nucleoli and eosinophilic, granular cytoplasm. Within the cytoplasm of the tumor cells, numerous PAS-positive granules were found. Immunostaining was positive for neuron-specific enolase(three of five cases), alpha1-antitrypsin and alpha1-antichymotrypsin(three of five cases) in the solid and papillary portion of the tumor. But no polypeptide hormone immunoreactive cells were present in all cases except for gastrin which showed focally weak positivity in the papillary area. Ultrastructurally, the papillary and solid epithelial neopasm of the pancreas showed evidence of acinar cell differentiation, because in the cell of one observed some zymogen-like granules and presence of annulate lamellae. But also, abundant typical neurosecretory granules were detected in the tumor cells ultrastructurally. Both facts suggested acinar and islet cell differentiation of the tumor. From the these findings, it concluded that papillary and solid epithelial neoplasm of the pancreas may be originated from a primordial cell which will be able to render both endocrine and exocine component.

Neurofibromatosis is a complex hereditary disease involving many organs and systems. The incidence in pregnancy is less frequent and has been reported as 1/5000 to 1/18500 deliveries. Therefore, little is known about the interactions between neurofibromatosis and pregnancy. A survey of relevant literature suggests that patients with NF have an increased risk of perinatal complications (pregnancy induced hypertension, IUGR, preterm labor, abortion, stillbirth, high cesarean section rate) and maternal disease aggravation (rupture of an aneurysm, sarcomatous degeneration of neurofibroma, activation of pheochromocytoma). Refined ultrasound, flow studies and fetal monitoring allow us to provide improved pregnancy care for neurofibromatosis. However, It should be remembered that even now, neurofibromatosis places pregnant women and their fetuses in a high risk group with the potential to develop life threatening complications. We report a case of vertebral artery aneurysm and preeclampsia complicating a pregnancy with neurofibromatosis."
