Left-sided appendicitis: diagnosis and minimally invasive treatment.

Intestinal malrotation and situs inversus can have important repercussions if acute abdominal pain develops. Intraabdominal structures can have inverted position and thus may easily mislead the surgeon during physical examination. Fortunately, radiological exams have improved the preoperative diagnosis of these patients. However, in difficult cases when an underlying surgical disease is suspected, laparoscopy remains the gold standard in order to diagnose and treat if possible the suspected disorder. We present a case of acute left-side appendicitis in a child with unknown congenital intestinal malrotation. In addition, this case stressed the value of laparoscopy in daily practice to evaluate patients with atypical abdominal pain.

Hypercalcemia associated with adenosquamous pancreatic carcinoma: a reason to initiate palliative treatment.

BACKGROUND: hypercalcemia in patients with diagnosed carcinoma has predominantly a humoral basis mediated by parathyroid hormone-related protein (PTH-rP). Among the reported cases, hypercalcemia associated with the majority of abdominal malignancies indicates an advanced stage of disease. CASE REPORT: we present a case of a 78-year-old patient with an adenosquamous pancreatic carcinoma associated with humoral hypercalcemia mediated by PTH-rP. CONCLUSION: in this case, demonstration of unexpectantly rapid increase in calcium serum correlated with aggressive tumor growth led us to raise the hypothesis that PTH-rP could be a mediator of invasion and dissemination secreted by some tumors, and probably indicates the appropriate time to initiate palliative treatment.
