Background:Fine needle aspiration cytology (FNAC) of oral and maxillofacial region has not been widely utilized for diagnosis due to diversity of lesion types, heterogeneity of cell populations and difficulties in reaching and aspirating these lesions.Aim:Our aim was to demonstrate the effectiveness of this cheap and simple procedure for the diagnosis of tumor and tumor like lesions of oral and maxillofacial region. In addition, we sought to highlight probable causes of errors in the cases showing lack of correlation between cytological and histological diagnoses.Materials and Methods:The study was conducted on 50 patients of all age groups with various palpable lesions in the oromaxillofacial region. A comparison between cytological and histological diagnosis was done wherever biopsy material was available.Results:The rate of unsatisfactory FNA was 4%. There were six false negative cases but no false positive case. The sensitivity of our study ranged from 77.7 to 75% including and excluding the suspicious cases, respectively. Specificity and positive predictive value was 100%.Conclusion:FNAC is a minimally invasive, highly accurate and cost-effective procedure for the assessment of patients with oromaxillofacial lesions. When applied in a proper manner, FNAC can help avoid a surgical biopsy in many cases.

BackgroundFibroscan is a quick, non-invasive technique used to measure liver stiffness (kPa), which correlates with fibrosis. To achieve a valid liver stiffness evaluation (LSE) the operator must obtain all the following three criteria: (1) ≥10 successful liver stiffness measurements; (2) IQR/median ratio <0.30 and (3) ≥60% measurement success rate.ObjectivesTo assess the operator training requirements and the importance of adhering to the LSE validity criteria in routine clinical practice.MethodsWe retrospectively analysed the LSE validity rates of 2311 Fibroscans performed (1 August 2008 to 31 July 2011) in our tertiary liver outpatients department at the University Hospital Birmingham, UK. The diagnostic accuracy of Fibroscan was assessed in 153 patients, by comparing LSE (valid and invalid) with the modified Ishak fibrosis stage on liver biopsy.ResultsLearning curve analysis highlighted that the greatest improvement in validity of LSE rates occurs in the operator’s first 10 Fibroscans, reaching 64.7% validity by the 50th Fibroscan. The correlation between LSE and the fibrosis stage on liver biopsy was superior in patients with a valid LSE (n=97) compared with those with an invalid LSE (n=56) (rs 0.577 vs 0.259; p=0.022). Area under receiving operating characteristics for significant fibrosis was greater when LSE was valid (0.83 vs 0.66; p=0.048). Using an LSE cut-off of 8 kPa, the negative predictive value of valid LSE was superior to invalid LSE for the detection of significant (84% vs 71%) and advanced fibrosis (100% vs 93%).ConclusionsFibroscan requires minimal operator training (≥10 observed on patients), and when a valid LSE is obtained, it is an accurate tool for excluding advanced liver fibrosis. To ensure the diagnostic accuracy of Fibroscan it is essential that the recommended LSE validity criteria are adhered to in routine clinical practice.

Heterotopic, aberrant or ectopic pancreas is defined as the presence of pancreatic tissue in topographic anomaly, with no anatomical, neural or vascular connection to the normal pancreas. It is a rare condition found mainly in stomach, duodenum and jejunum. Ileal heterotopic pancreas is an uncommon condition and has been rarely reported in children so far. Hereby we report a case of heterotopic pancreas presenting as ileal poyp leading to ileoileal intussusception in a 12 year child.

The incidence of fascial dehiscence and incisional hernia after two methods for abdominal wound closure (rectus sheath relaxation incisions and conventional mass closure) was studied in a randomized prospective clinical trial in a consecutive series of 100 patients undergoing midline laparotomy for peritonitis. The two groups were well matched for etiologies of peritonitis, the surgical procedures performed, and the presence of known risk factors for fascial dehiscence. Fifty patients each were randomized either to the conventional continuous mass closure procedure or the rectus sheath relaxation incision technique (designed to increase wound elasticity and decrease tension in the suture line) using identical polypropylene sutures. The incidence of postoperative complications such as duration of ileus, chest infection, and wound infection were not statistically different between the two groups. The intensity of postoperative pain in the rectus sheath relaxation incision group was significantly less. The incidence of wound hematoma was significantly increased in the rectus sheath relaxation incision group. The incidences of fascial dehiscence (16% vs,28%; p < 0.05) and incisional hernia (18% vs, 30%; p < 0.05) were significantly lower after rectus sheath relaxation incisions compared to conventional mass closure. Closure of the midline laparotomy wound in cases of peritonitis using the rectus sheath relaxation technique is safe and less painful, provides increased wound elasticity and decreased tension on the suture line, and significantly decreases the incidence of wound dehiscence.
