Torsion of a mucocele of the vermiform appendix is an extremely rare condition and also a rare cause of an acute abdomen with a clinical presentation that is indistinguishable from acute appendicitis, and thus, the condition is diagnosed during operation. Here, the authors describe the case of a 78-year-old female, who presented with intermittent abdominal pain. The appendix had a pelvic position and the torsion was counterclockwise. In addition, the torsion was associated with mucocele of the appendix, which was considered a secondary factor of torsion. Appendectomy and drainage were performed.

Somatic mutations that lead to hyperactivation of epidermal growth factor receptor (EGFR) signaling are detected in approximately 50% of lung adenocarcinoma in people from the Far East population and tyrosine kinase inhibitors are now the standard first line treatment for advanced disease. They have led to a doubling of progression-free survival and an increase in overall survival by more than 2 years. However, emergence of resistant clones has become the primary cause for treatment failure, and has created a new challenge in the daily management of patients with EGFR mutations. Identification of mechanisms leading to inhibitor resistance has led to new therapeutic modalities, some of which have now been adapted for patients with unsuccessful tyrosine kinase inhibitor treatment. In this review, we describe mechanisms of tyrosine kinase inhibitor resistance and the available strategies to overcoming resistance.

When ultrasound or computed tomographic (CT) scans demonstrate a focal mass within the pancreas, the radiologist or gastroenterologist assumes that it is carcinoma. Statistically this is the correct diagnosis. However, distinguishing pancreatitis from carcinoma by ultrasound and CT is occassionally impossible. Similarly, abnormalities seen on ERCP, such as simultaneous obstruction of both the common bile duct and adjacent pancreatic duct (double duct sign), has been shown to occur in pancreatitis as well as in the more commonly diagnosed pancreatic carcinoma. We experienced 3 cases af focal pancreatic masses that mistaken a carcinoma. And so, knowledge that such a mass can be benign in a clinical setting sbould result in an organiged approach to the correct diagnosis and avoidance of any unnecessary operations.

To investigate the relationship between insulin response and morphometric changes of the mitochondria of pancreatic beta-cell, this study was performed using hyperglycemia and streptozotocin as oxidative stresses. Adult and neonatal rats were used. Intravenous glucose tolerance test (IVGTT) and morphologic examination of pancreas using immunohistochemical stain, in situ end-labeling method and electron microscopic study were performed. Various mitochondrial parameters were measured by image analyzer. Immunohistochemical stain revealed a markedly reduced islet size and decreased number of beta-cells and the increased number of non-beta-cell in adult and neonatoal streptozotocin group, and the appearance of insulin positive cells throughout the exocrine parenchyma in neonatal streptozotocin group. Three days after injection of streptozotocin in adult streptozotocin group, TUNEL stain showed increased apoptotic cells in islets. Ultrastructurally, beta-cells in adult streptozotocin group showed increase in number and size of mitochondria, and disruption of mitochondrial structures. Hyperglycemic group and neonatal streptozotocin group showed preserved mitochondrial ultrastructure. Ultrastructural morphometric study revealed increase in size and number of mitochondria and decrease in mitochondrial contour index in adult streptozotocin-treated rats, which suggested mitochondrial degeneration. Hyperglycemic group showed mild increase in size of mitochondria. Increased number of mitochondria was also observed in neonatal streptozotocin group. IVGTT revealed marked decrease in insulin response in adult streptozotocin group, and non-insulin-dependent diabetes mellitus pattern in glucose and insulin response in neonatal streptozotocin group. Hyperglycemic group showed a glucose and insulin response similar to control group. The above results suggest that a severe oxidative injury may cause degeneration and disruption of mitochondria of pancreatic beta-cell, and may be associated with substantial apoptotic cell death. The changes in the morphology and the number of mitochondria may result from streptozotocin treatment within neonatal period and hyperglycemia treatment, which may be associated with changes in insulin response.

A 13-year-old male presented with a walnut-size tender swelling of the left supraclavicular area. The lesion developed 4 months after BCG vaccination in a left. upper arm location. The supraclavicular lesion gradually increased in size and became suppurative witii resultant sinus formation. Histopathological examination of the nodular lesion showei3 foci of epithelioid granulomas with caseation necrosis, and several Langhans' type giant cells. After a diagnosis of BCGitis was made, the patient was, treated with isoniazid an l rifampin for two months without much benefits. Surgical excision of the lesion were performed to expedite clinical regression. After six months of antituherculous chemctherapy, a clinical remission was evident. Scrofuloderma-like BCGitis as well as other cutaneous complications of BCG vaecination are not uncommon. Thus, the practicing dermatologist should be aware of these complications, for correct diagnosis and treatment.
