During a recent 12-month period, serum iron levels, total iron binding capacities (TIBC), and latent iron binding capacities (LIBC) were studied preoperatively and 72 hrs postoperatively in 33 consecutive patients with pathologically confirmed acute appendicitis. Preoperative serum iron levels were significantly reduced in these patients (mean serum iron 32 micrograms/dl; P less than .0001) compared to established normal values (mean 100 micrograms/dl). LICBs were correspondingly elevated whereas TIBCs and mean hemoglobin values remained within the normal range. The reduced availability of serum iron in response to an acute infectious challenge such as appendicitis supports earlier experimental studies by others which suggest that nutritional immunity participates in host resistance to infection. In this study, the degree of serum iron suppression was directly related to the severity of disease (P less than .01).

One trocar appendectomy is a combination of laparoscopic and open appendectomy. The advantage, along with improved cosmesis, is the possibility to introduce a dissection instrument through the optical trocar without an additional incision. In this prospective study the sense of one trocar appendectomy is evaluated in daily practise for a cohort of consecutive patients with suspected acute appendicitis. Twenty-two patients were enrolled. One-trocar appendectomy was successful in 13 patients. In 8 patients one extra 2, 5 or 10 millimetre trocar was necessary. In one patient a third trocar was necessary. Conversion to an open appendectomy through a grid iron incision was not necessary. The pathologist confirmed the diagnosis of acute appendicitis in all patients. The average operation time was 53 minutes. Complications included one wound abscess and one wound haematoma. In conclusion one trocar appendectomy is a good and safe technique in patients with the suspicion of acute appendicitis, provided that the operative team must be experienced in laparoscopic surgery and the constitution of the patient is suitable for this technique.

In our study we investigated serum iron levels in the patients with localized or generalized peritonitis. These values were compared in group of 52 patients with acute peritonitis against group of 39 patients without inflammation within peritoneal cavity. The serum iron levels and Total Iron Binding Capacity (TIBC) was indicated in both group. Acute intraabdominal inflammation induced in all patients a state of hypoferremia. However, medium decline of iron level in patients with acute appendicitis or cholecystitis was smaller compare with that observed among the patients with generalized peritonitis caused by perforation of duodenal ulcer, perforation of large bowel diverticula or perforation of small bowel. It has been suggested that decline in iron serum level observed in those patients can be an element of metabolic response to trauma and represents a part of the innate immune system and thus constitutes the first line defence against infection. However, based on presently available knowledge we can not yet finally evaluate the clinical implication of serum iron monitoring in diagnosis and prognosis of the patients with peritonitis.

Primary malignancies of the appendix are rare. Of these, less than 5% are goblet cell carcinoid (GCC) tumours. The majority of GCC present with findings of acute appendicitis or advanced peritoneal spread. We describe a rare presentation of GCC as subtle mucosal abnormality of the appendiceal orifice seen on colonoscopy performed for iron-deficiency anaemia. Biopsies were interpreted as adenocarcinoma; however, final surgical pathology confirmed GCC of the appendix with caecal involvement. The patient recovered well from surgery, anaemia resolved and follow-up did not show metastatic disease.

For decades, the neurotoxicity caused by anesthetics in mammalian brain development has gained increasing attention. Exposure to anesthetics leads to neurotoxicity and apoptosis of nerve cells, which in turn induces cognitive dysfunction. Although most of the data came from animal studies, general anesthetics have been shown to have adverse effects on cognitive function in infants and young children in recent years. This concern has led to a number of retrospective studies that observed an association between general anesthesia in pregnant women and neurobehavioral problems in fetuses or offspring. Every year, many pregnant women undergo non-obstetric anesthesia due to various reasons such as traffic accidents, fetal interventions, acute appendicitis, symptomatic cholelithiasis, and trauma. A matter of concern for these pregnant women is whether anesthesia has a detrimental effect on fetal brain development in the womb and whether the fetus has cognitive impairment after birth. In humans, the association of anesthetic exposure in infants with the long-term impairment of neurologic functions has been reported in several retrospective clinical studies. Recently, we have found that sevoflurane anesthesia during pregnancy in mice induced cognitive impairment in the offspring by causing iron deficiency and inhibiting myelinogenesis. Sevoflurane is a commonly used general anesthetic in the hospitals, which can induce neurotoxicity and cause cognitive impairment in fetuses, infants, children, and adults. However, the exact mechanism of sevoflurane-induced damage to the central nervous system (CNS) is not fully understood. Based on our recent results, this paper reviewed the effects of sevoflurane on cognitive impairment and pathological changes such as neurogenesis, neuronal apoptosis, and iron metabolism dysfunction in the offspring.
