ABSTRACT
AIM: Various surgical techniques are available for the management of pilonidal sinus, but there is still controversy concerning the optimal surgical approach. The aim of our study was to evaluate the safety, efficacy and clinical outcome of a laser procedure for the treatment of pilonidal sinus. METHOD: Patients suffering from pilonidal sinus were operated on with sinus laser therapy (SiLaT) in our institute. SiLaT was applied under local anaesthesia after a small skin incision of 0.5-1 cm and careful cleaning of the sinus tracts with a curette. A radial fibre connected to a diode laser set at a wavelength of 1470 nm was then introduced into the tracts. The laser energy was delivered in continuous mode. RESULTS: Two-hundred and thirty-seven patients (183 male, median age 24 years, range 14-58) suffering from pilonidal sinus were operated on using the SiLaT laser procedure in our referral Institute and prospectively evaluated. A high healing rate was observed after the first session (90.3%, 214 of 237) with a median healing time of 47 days (range 30-70 days). A second treatment was offered for patients failing in the first session; this was successful in 78.3% (18/23). The duration of the procedure ranged between 20 and 30 min and had limited morbidity (wound infection in 7.2%, 17 of 237). CONCLUSION: SiLaT proved to be a safe and effective procedure for treating patients suffering from pilonidal sinus. Clinical results showed low morbidity and recurrence rates comparable to the published literature for other modern techniques.

Mouth cancer is a major health problem. Multiple risk factors for developing mouth cancer have been studied and include history of tobacco and alcohol abuse, age over 40, exposure to ultraviolet radiation, human papilloma virus infection (HPV), nutritional deficiencies, chronic irritation, and existence or oral potentially malignant lesions such as leukoplakia and lichen planus. An important risk factor for mouth cancer is chronic immunosuppression and has been extensively reported after solid organ transplantation as well as HIV-infected patients. Diagnosis of inflammatory bowel disease (IBD) is not yet considered as a risk factor for oral cancer development. However, a significant number of patients with IBD are receiving immunosuppressants and biological therapies which could represent potential oral oncogenic factors either by direct oncogenic effect or by continuous immunosuppression favoring carcinogenesis, especially in patients with HPV(+) IBD. Education on modifiable risk behaviors in patients with IBD is the cornerstone of prevention of mouth cancer. Oral screening should be performed for all patients with IBD, especially those who are about to start an immunosuppressant or a biologic.

PURPOSE: To present a case series of two fraternal twin girls who passed away from brain and colorectal cancers attributed to Constitutional Mismatch Repair Deficiency syndrome (CMMRD). A review of literature for CMMRD-related pediatric malignancies is also presented. METHODS: The two girls were diagnosed with cancer at the age of 11 and 13 respectively. The early onset of multiple malignancies in the family raised clinical suspicion for a potential genetic mutation. The presence of café-au-lait spots at clinical examination led to further investigations for neurofibromatosis. RESULTS: Neurofibromatosis type 1 testing was negative in both children. Genetic analysis turned out positive for biallelic MSH6 mutations in the two girls, leading to CMMRD syndrome diagnosis. Both parents and two out of three alive siblings were diagnosed with Lynch syndrome. CONCLUSIONS: Colorectal cancer is a very rare finding in childhood and should raise suspicion for CMMRD syndrome and should be followed by regular screening.

OBJECTIVE: To determine dysplasia and cancer in the 1991-2004 European Collaborative Inflammatory Bowel Disease (EC-IBD) Study Group cohort. PATIENTS AND METHODS: A patient questionnaire and a physician per patient form were completed for each of the 1,141 inflammatory bowel disease patients (776 ulcerative colitis/365 Crohn's disease) from 9 centers (7 countries) derived from the EC-IBD cohort. Rates of detection of intestinal cancer and dysplasia as well as extra-intestinal neoplasms were computed. RESULTS: Patient follow-up time was 10.3 +/- 0.8 (range 9.4-11) years. The mean age of the whole group of IBD patients was 37.8 +/- 11.3 (range 16-76) years. Thirty-eight patients (3.3%; 26 with ulcerative colitis/12 with Crohn's disease, 21 males/17 females, aged 61.3 +/- 13.4, range 33-77 years), were diagnosed with 42 cancers. Cancers occurred 5.4 +/- 3.3 (range 0-11) years after inflammatory bowel disease diagnosis. Colorectal cancer was diagnosed in 8 (1 Crohn's disease and 7 ulcerative colitis patients--0.3 and 0.9% of the Crohn's disease and ulcerative colitis cohort, respectively) of 38 patients and 30 cancers were extra-intestinal. Four of 38 patients (10.5%) were diagnosed as having 2 cancers and they were younger compared to patients with one cancer (p = 0.0008). There was a trend for a higher prevalence of intestinal cancer in the northern centers (0.9%) compared to southern centers (0.3%, p = NS). Southern centers had more cases of extra-intestinal cancer compared to northern centers (2 vs. 3.8%, p = 0.08). Ten patients (0.9%; 8 with ulcerative colitis/2 with Crohn's disease, 8 males, aged 62.3 +/- 14.1 years) had colorectal dysplasia. CONCLUSIONS: In the first decade of the EC-IBD Study Group cohort follow-up study, the prevalence of cancer was as expected with most patients having a single neoplasm and an extra-intestinal neoplasm. In northern centers there was a trend for more intestinal cancers, while in southern centers there was a trend for more extra-intestinal cancers compared to northern centers.

BACKGROUND: Capsule endoscopy (CE) is a valuable tool in the diagnostic evaluation of obscure gastrointestinal bleeding, but limited information is available on the reproducibility of CE findings. OBJECTIVE: To compare two successive CE studies with push enteroscopy (PE) in patients presenting with chronic obscure gastrointestinal bleeding. METHODS: A prospective study was conducted. Ten patients (seven men and three women) with chronic obscure gastrointestinal bleeding and no contraindications for CE were eligible and completed the trial. For each patient, the first capsule was administered on day 1, the second capsule was administered on day 2 and PE was performed on day 3. Endoscopists were blinded to the capsule findings. Capsule findings were assessed independently by two investigators blinded to PE findings. RESULTS: A potential small intestinal bleeding source was found in 60% of the patients when all the studies were combined. A bleeding source was found in four patients in both CE studies. The second CE also identified a bleeding source in a fifth patient. Interobserver agreement by kappa analysis was 0.642 to 1.000 (P < or 05) for the CE studies. PE identified a potential small bowel bleeding site in four patients, including one patient who had negative CE studies. CONCLUSIONS: This study confirmed the reproducibility of CE findings on successive studies. Some patients did not have a source of bleeding in the small intestine, and all studies found this.

BACKGROUND: Inflammatory bowel disease mainly affects the bowel but also has extraintestinal manifestations. AIMS: To report the frequency of extraintestinal manifestations in patients with inflammatory bowel disease in Northwest Greece. PATIENTS; The data files of 256 inflammatory bowel disease patients (diagnosis between 1983-19971 were analysed. METHODS: Retrospective investigation of patient files. RESULTS: In patients with ulcerative colitis: 13.9% (30/215) had developed skin manifestations, 6% (13/215) had kidney stones, 1.39% (3/215) had iridocyclitis, 1.86% (4/215) had primary sclerosing cholangitis, 4.18% (9/215) had sacroiliitis, 8.31% (18/215) had peripheral arthalgias, 2.3% (5/215) had colitic arthritis and finally 1.39% (3/215) had deep vein thrombosis). In patients with Crohn's disease: 24.3% (9/37) had developed skin manifestations, 5.4% (2/37) had kidney stones, 2.7% (1/37) had iridocyclitis, 16.2% (6/37) had sacroiliitis, 8.1% (3/37) had peripheral arthralgias, 5.4% (2/37) had colitic arthritis and, finally, 8.1% (3/37) had deep vein thrombosis. Sacroiliitis (p = 0.01), deep vein thrombosis (p = 0.04) and erythmema nodosum (p = 0.01) were more common in patients with Crohn's disease. CONCLUSIONS: Extraintestinal manifestations are not rare in patients with inflammatory bowel disease, especially in Crohn's disease patients, in our area, but have, generally, a mild profile.

Hyperemesis gravidarum is defined as severe nausea and vomiting during the first trimester of pregnancy. It is characterized by dehydration, electrolyte imbalance, ketonuria and weight loss of more than 5% of body weight and it usually requires hospitalization. Traditionally, total parenteral nutrition has been used when patients with hyperemesis gravidarum fail to respond to conservative measures, including dietary manipulation and antiemetics. Total parenteral nutrition has been shown to be an effective method of nutritional support during pregnancy but it is expensive and has potentially serious complications. Peripheral parenteral nutrition reduces the risk of complications, but caloric intake is limited. A small number of investigators have suggested using enteral nutrition as an alternative to total parenteral nutrition. Herein we report two cases of hyperemesis gravidarum successfully treated with an effective regimen of peripheral parenteral nutrition.

BACKGROUND: An increased risk of colorectal cancer in ulcerative colitis (UC) and Crohn's disease (CD) has been reported. No data on inflammatory bowel disease (IBD)-related dysplasia and cancer is available in Greece, where the disease profile seems to be milder than that of northern Europe. METHODS: A study was conducted of 215 IBD patients (182 with UC, 33 with CD) from a referral center. Patients were followed up for 3-18 years. The prevalence of cancer and dysplasia among the IBD patients who were diagnosed in northwestern Greece was analyzed and registered. Statistical analysis was performed assuming that this IBD cohort had the same risk of developing malignancies as the general population in Greece. RESULTS: Six of the 215 patients in this IBD cohort had cancer, and 20 of 126 patients for whom bowel biopsies were available had dysplasia. Three of these cases were high-grade dysplasia. There was no significant difference in the numbers of calculated and expected cases of IBD-related cancer at any sites except for the skin [2.7 vs. 2.0]. CONCLUSIONS: This IBD cohort did not appear to have an increased risk of cancer during the time period studied. It would be interesting to re-assess the risk after the second and third decades of follow-up.
ABSTRACT
BACKGROUND: Although controversial, some authorities have implicated hepatitis C virus (HCV) as a cause of anti-phospholipid syndrome (APLS). Anti-cardiolipin antibodies (anti-CLAbs) in APLS are cofactor-dependent ('pathogenic' antibodies). We conducted a study in order to determine the prevalence of anti-CLAbs in HCV patients, and furthermore to address whether these autoantibodies are cofactor-dependent or not and whether they are associated with features of APLS. Patients with hepatitis B virus (HBV) were also evaluated in order to assess whether there are differences in the prevalence and the clinical significance of anti-CLAbs between these two major types of chronic viral hepatitis. MATERIALS AND METHODS: One hundred and seventy-four consecutive HCV patients, 50 HBV patients and 267 healthy were investigated for the presence of anti-CLAbs and antibodies against beta2-glycoprotein I (beta2-GPI), which is the most important cofactor of the 'pathogenic' anti-CLAbs in APLS. IgG anti-CLAbs were determined by an in-house quantitative ELISA and anti-beta2-GPIAbs using a commercial ELISA kit. RESULTS: 21.3% of the HCV and 14% of the HBV patients tested positive for IgG anti-CLAbs (P < 0.0001 compared with healthy controls). Neither age, sex, certain epidemiologic and laboratory parameters nor the clinical status and the histologic findings were associated with anti-CLAbs detection in both diseases. 2.3% of the HCV (P < 0.05 compared with healthy controls) and 2% of the HBV patients tested positive for anti-beta2-GPIAbs. Presence of anti-CLAbs was not associated with features of APLS. CONCLUSIONS: A significant proportion of the HCV and HBV patients had detectable IgG anti-CLAbs. However, the anti-CLAbs titres were relatively low, and in most cases seem to be cofactor-independent ('nonpathogenic'). The latter is further supported by the lack of their association with clinical features of APLS. Furthermore, anti-CLAbs appear to be detected irrespective of the demographic, laboratory, clinical and histologic status in both HCV and HBV. However, prospective studies of longer duration may be required in order to address whether anti-CLAbs in patients with chronic viral hepatitis are or are not of clinical importance.

Background: Essential mixed cryoglobulinemia (EMC) is a systemic disease frequently associated with chronic viral hepatitis. This study was conducted in order to assess the prevalence of EMC in patients with hepatitis B virus (HBV) or hepatitis C virus (HCV) infections. We also evaluated the possible associations of EMC with (1) the clinical, virological, and histological status of liver disease; (2) the presence of EMC-related symptoms; and (3) the response rate to interferon-alpha (IFN-alpha) treatment, in an attempt to address whether EMC is a major problem in hepatitis patients. Methodology: A total of 154 consecutive patients (104 with HBV and 50 with HCV infection) were investigated for the presence of rheumatoid factor (RF), cryoglobulins, and EMC-related manifestations. Sixty-two HBV patients were chronic carriers of hepatitis B surface antigen, 29 had chronic hepatitis B, and 13 HBV cirrhosis. Thirty-five HCV patients had chronic hepatitis C and 15 HCV cirrhosis. HCV genotyping was performed in 44 patients. Results: The prevalence of cryoglobulins was significantly higher (P<0.001) in HCV patients (46%) than in HBV patients (13.4%). EMC was associated with a high frequency of RF detection, older age, and longer duration of viral diseases. Weakness or malaise, arthralgias, and purpura were significantly more frequent in cryoglobulin-positive patients. These manifestations, however, were mild in most of the patients. The EMC-related symptoms were significantly associated with the presence of HCV infection, increased levels of cryoglobulins, and RF detection (P<0.01, P<0.05, and P<0.000005, respectively). Worse liver histology was unrelated to a higher prevalence or increased levels of cryoglobulins in both HBV and HCV infection. There was no relationship between EMC and a specific HCV genotype. IFN-alpha therapy led to the disappearance of cryoglobulins and EMC-related manifestations in most cases. The response rate to IFN-alpha was similar in both groups of patients (with and without EMC). Conclusions: A higher prevalence of EMC was observed in HCV patients than in HBV patients. However, this finding was unrelated to overt clinical manifestations of EMC, a specific HCV genotype, or worse liver histology. The latter suggests that EMC does not contribute to liver injury and vice versa, that EMC pathogenesis is rather unrelated to the degree of liver injury. From a clinical point of view, testing for cryoglobulins seems reasonable only for HCV patients with EMC-related manifestations, since this may have therapeutic consequences. RF detection could be used primarily as a surrogate marker for the existence of cryoglobulins.
