Helicobacter pylori (H. pylori) is one of the most common human bacterial infections with prevalence rates between 10-80% depending upon geographical location, age and socioeconomic status. H. pylori is commonly found in patients complaining of dyspepsia and is a common cause of gastritis. During the course of their infection, people living with HIV (PLHIV) often have a variety of gastrointestinal symptoms including dyspepsia and while previous studies have reported HIV and H. pylori co-infection, there has been little data clarifying the factors influencing this. The aim of this case-control study was to document the prevalence of H. pylori co-infection within the HIV community as well as to describe endoscopic findings, gastritis topography and histology, along with patient demographic characteristics across three different periods of time during which antiretroviral therapy (ART) has evolved, from pre- highly active antiretroviral therapy (HAART) to early and modern HAART eras. These data were compared to well-matched HIV negative controls. Two hundred and twelve PLHIV were compared with 1,617 controls who underwent their first esophagogastroduodenoscopy (EGD) to investigate dyspepsia. The prevalence of H. pylori co-infection among PLHIV was significantly higher in the early (30.2%) and modern HAART period (34.4%) compared with those with coinfection from the pre-HAART period (18.2%). The higher rates seen in patients from the HAART eras were similar to those observed among HIV negative controls (38.5%). This prevalence increase among co-infected patients was in contrast to the fall in prevalence observed among controls, from 60.7% in the early period to 52.9% in the second observed period. The three PLHIV co-infected subgroups differed regarding gastritis topography, morphology and pathology. This study suggests that ART has an important impact on the endoscopic and histological features of gastritis among HIV/H. pylori co-infected individuals, raising the possibility that H. pylori-induced gastritis could be an immune restoration disease.
RESUMO
BACKGROUND: To assess the prevalence and risk factors of celiac crisis (CC) in children with classical celiac disease (CD). METHODS: This retrospective study comprised 367 children with classical CD diagnosed from 1994 to 2015. The diagnosis of CD was based on the revised ESPGHAN criteria and CC on acute worsening and rapid progression of chronic diarrhea and vomiting followed by severe dehydration, multiple metabolic derangements and a marked decrease of body weight. RESULTS: Celiac crisis was confirmed in six (1.63 %) children, five in the first and one in the second year of life. In three patients CC was precipitated by rotavirus and in one by Salmonella enteritidis infection, while in the remaining two, except for a too long-standing disease and severe malnutrition, no additional causes of CC were found. CONCLUSION: Celiac crisis in Serbia is still-present in children exclusively below the second year of life as a spontaneous or intestinal infection precipitated complication of previously unrecognized CD.

Composite hemangioendothelioma (CHE) is a rare, locally aggressive, vascular tumor of intermediate-/ low-grade malignancy, and is characterized by varying combinations of benign, low-grade malignant, and malignant vascular components. In cutaneous localization, only 22 cases have been reported so far. A new case of CHE of the gluteal region in a 58-year-old man is described. Microscopically, vascular neoplasm, situated mainly within the deep dermis and the subcutaneous fat tissue, was composed of sinusoidal hemangioma, arteriovenous hemangioma, retiform hemangioendothelioma (RHE), and angiosarcoma. An average number of mitoses within the angiosarcomatous component was 10 per 10 high-power fields. Immunohistochemically, the tumor cells were positive for factor VIII-related antigen, CD34, and CD31 and negative for D2-40 and GLUT-1. Ki-67 labeling index was 21%, 1.2%, and 0% in the areas of angiosarcoma, RHE, and sinusoidal hemangioma, respectively. No recurrent disease was noted 3 months after the surgery. The present case displayed the following features previously undescribed in CHE: a novel component of sinusoidal hemangioma and localization at the gluteal region. We also provide review of clinical, histopathological, and immunohistochemical characteristics of cutaneous CHE from the published cases.

The benign cystic mesothelioma of the peritoneum is a rare lesion that occurs predominatly in women of reproductive age and has a high propensity for local recurrence. It is very rare in childhood, especially in boys, being reported in only 4 cases. A new case of benign cystic mesothelioma of the peritoneum in an 11-year-old boy is reported. The lesion occupied the entire left abdomen, arising from the transverse mesocolon, and it was accompanied by 4 small cysts. The patient had a coexistent right-sided renal agenesis. The mesothelial nature of the cysts epithelial lining cells was confirmed by immunopositivity for calretinin, cytokeratin 5/6, HBME1, and epithelial membrane antigen (EMA). No recurrence of the lesion was noted in the 7-month follow-up. Pathologists and clinicians should be aware of the existence of this rare entity in childhood to establish an accurate diagnosis and provide close follow-up after the surgery.

INTRODUCTION: Idiopathic ulcerative colitis (IUC) represents a rare disease of childhood. It usually occurs at age over 10 years, and below that exceptionally rarely. OBJECTIVE: The aim of the paper was to analyze the clinical signs, symptoms and therapeutic procedures in children with IUC. METHODS: The aims of the paper were based on a sample of 17 children (11 male and 6 female, mean age 11.90 +/- 3.50 years; range 3.8-17.5 years) with IUC. The disease diagnosis was based on characteristic endoscopic and pathohistological findings. RESULTS: The basic signs of the disease involved chronic mucosal haemorrhagic diarrhoea which was confirmed in 16 of 17 patients, with body weight deficiency (10), recurrent abdominal pain (6), fever (5), slowed-down maturation (5), marked anorexia (4), and tenesmus (3).Two patients had recurrent aphthous stomatitis, 2 anal fissures, 2 arthralgia, one autoimmune hepatitis and one pyoderma gangrenosum. None of the children had longitudinal growth retardation. Elevated sedimentation rate and C-reactive protein in blood were registered in 11, sideropenia in 10, anaemia in 6 and hypoalbuminemia in 3 patients. The remission of proctosigmoiditis and left-sided colitis was achieved with aminosalicylates, and of pancolitis with the combination of aminosalicylates and glucocorticoids, except in cases of steroid-dependent colitis, which additionally required azathioprine. CONCLUSION: The main signs of IUC in children are chronic mucous haemorrhagic diarrhoea, body weight loss and sideropenic anaemia, while the basic therapy consists of aminosalicylates, and in more severe cases of the disease the initial use of glucocorticoids and later azathioprine.

BACKGROUND AND AIMS: The existence, histology and origin of gastric cardiac mucosa are controversial. The aim of the present study was to determine the existence, histological characteristics and length of cardiac mucosa and to correlate these features with the patients' age and the presence of inflammation in the gastric cardia and/or esophagus. METHODS; The cardiac mucosa within the whole esophagogastric junction was histologically analyzed in 38 consecutive autopsy specimens and measured in 24 cases. RESULTS: The cardiac mucosa was identified in all specimens from all cases, with a mean length of 6.7 mm, range 0.927-19.5 mm. In the majority of cases, the length of cardiac mucosa was less than 10 mm (87.5%) and greater than 5 mm (71%). Cardiac mucosa was composed of a combination of pure mucous glands and mucous glands with parietal cells in 74% of cases, and only of mucous glands with parietal cells in 26% of cases. Carditis was recorded in 23.7% cases and reflux esophagitis in 15.8%. The length of cardiac mucosa was not significantly different between cases with and without carditis (p>0.05), between those with and without esophagitis (p>0.05), and between age groups older and younger than 60 years (p>0.05). CONCLUSION: In the adult population, a short histological segment of gastric cardia was consistently present as a normal histological structure. The type, length and circumferential presence of cardiac mucosa were not significantly associated with carditis, esophagitis or age.

We present a case of large cell lung carcinoma in sixty-one year old male with typical lung cancer symptoms but unusual radiological presentation and immunophenotype. Tumor morphological finding related to its radiological finding was suggestive for large cell lymphoma or carcinoma, but its immunophenotype made confusion for pathological diagnosis. No p53 mutations were detected in genetic investigation. Multidisciplinary diagnostic approach to some tumors is useful for their final diagnosis.

AIM: To investigate whether duration of breastfeeding and timing of gluten introduction influence the age at diagnosis and severity of celiac disease. METHODS: Medical records of 89 infants (59 girls and 30 boys; mean age of 14.2 months, standard deviation 4.80) diagnosed with classic celiac disease at the University Children's Hospital in Belgrade from 2000 to 2008 were retrospectively analyzed to determine the duration of breastfeeding and timing of gluten introduction. The severity of celiac disease was assessed based on weight loss, longitudinal growth retardation, anemia, and secondary lactose intolerance. RESULTS: Longer breastfeeding significantly reduced the risk that celiac disease would manifest in the first year of life (odds ratio, 0.655; 95% confidence interval, 0.481-0.891; P=0.007), and duration of breastfeeding was the most significant predictor of developing celiac disease (B=0.49; 95% confidence interval, 0.131-0.768; P=0.007). There were no significant differences in age at diagnosis between infants who had started consuming gluten before the fourth month and those who had started between the fourth and sixth month. Neither breastfeeding nor timing of gluten introduction affected the severity of the disease. CONCLUSION: Longer breastfeeding and continuation of breastfeeding after gluten introduction delay the onset of classic celiac disease. On the other hand, neither breastfeeding nor the timing of gluten introduction affects the severity of celiac disease.

INTRODUCTION: Coeliac disease (CD) is a permanent intolerance of gluten, i.e., of gliadin and related proteins found in the endosperm of wheat, rye and barley. It is characterized by polygenic predisposition, autoimmune nature, predominantly asymptomatic or atypical clinical course, as well as by high prevalence in patients with Down's syndrome (DS) and some other diseases. OUTLINE OF CASES: We are presenting a girl and two boys, aged 6-7 (x = 6.33) years with DS and CD recognized under the feature of sideropenic anaemia resistant to oral therapy with iron. Beside mental retardation, low stature and the morphological features characteristic of DS, two patients had a congenital heart disease; one ventricular septal defect and the other atrioventricular canal. In two patients, trisomy on the 21st chromosome pair (trisomy 21) was disclosed in all cells, while one had a mosaic karyotype. All three patients had classical laboratory parameters of sideropenic anaemia: blood Hb 77-89 g/l (x = 81.67), HCT 0.26-0.29% (x = 0.28), MCV 69-80 fl (x = 73), MCH 24.3-30 pg (x = 26.77) and serum iron 2-5 micromol/L (x = 4.0). Beside anaemia and in one patient a mild isolated hypertransaminasemia (AST 67 U/l, ALT 62 U/l), other indicators of CD were not registered in any of the children. In addition, in all three patients, we also detected an increased level of antibodies to tissue transglutaminase (atTG) of IgA class (45-88 U/I) so that we performed endoscopic enterobiopsy in order to reliably confirm the diagnosis of CD. In all three patients, the pathohistological finding of the duodenal mucosa specimen showed mild to moderate destructive enteropathy associated with high intraepithelial lymphocyte infiltration, cryptic hyperplasia and lympho-plasmocytic infiltration of the stroma. In all three patients, the treatment with a strict gluten-free diet and iron therapy applied orally for 3-4 months resulted in blood count normalization and the correction of sideropenia. Serum level of the atTG-IgA, repeated after a 12-month diet, was also normal. CONCLUSION: CD should be taken into consideration in all cases of sideropenic anaemia resistant to iron oral therapy in children with DS.The diagnosis of CD implicates corresponding pathohistological confirmation, while the treatment of sideropenic anaemia and its complications, beside iron preparations, also requires compliance with a gluten-free diet.

The coexistence of Down syndrome (DS) and celiac disease (CD) has been reported in many studies. In our study, we examined 82 children with DS aged 8 months to 8.6 years for the existence of CD using serological markers immunoglobulin A (IgA) and immunoglobulin G (IgG) transglutaminase antibodies, followed by follow-up determination of total IgA levels. In four children who were positive for one of the above-mentioned antibodies, enteric biopsy has been performed that showed absence of CD. Our findings raise doubt about the need for obligatory serological screening of children with DS aged <8 years.

BACKGROUND: There is positive correlation between the number of activated hepatic stellate cells and necroinflammatory activity and/or the stage of liver fibrosis in viral hepatitis. No study has investigated such a relationship with regard to the activated hepatic cells within specified zones of liver tissue in chronic C hepatitis. The aim of the present study was to correlate the level of activated hepatic stellate cells within perivenular, intermediate, periportal, and portal tracts area and fibrous septa with stages of liver fibrosis and necroinflammatory activity in patients with chronic C hepatitis. METHODS: This retrospective study included 20 liver biopsy samples from patients with chronic C hepatitis and 10 normal liver biopsies. Biopsy specimens were processed routinely and stained with haematoxylin-eosin, periodic acid-Schiff, Masson;s trichrome, aldechide fuchsin, reticulin and iron (Pearls). Activated hepatic stellate cells were identified immunohistochemically using antibody to alpha-smooth muscle actin. Assessment of immunoreactivity was performed using a semiquantitative method. RESULTS: In chronic C hepatitis, a positive correlation between the stage of fibrosis and the number of activated hepatic stellate cells within portal spaces and fibrous septa was found. These cells were increased in number in other areas of liver tissue as well, but without statistical significance. There was no correlation between either the stage of fibrosis and necroinflammatory activity or the number of activated hepatic stellate cells and necroinflammatory activity. CONCLUSION: An increased number of activated hepatic stellate cells within portal spaces and fibrous septa may be a useful prognostic marker for the development of advanced fibrosis and cirrhosis in chronic C hepatitis.

Myoepitheliomas are tumors of myoepithelial cells, most frequently diagnosed in the salivary glands. Cutaneous location is very rare, especially for malignant variant. We report a case of recurrent cutaneous myoepithelial carcinoma of the femoral region in a 51-year-old woman. Histologically, the tumor was confined to the dermis and superficial subcutaneous fat tissue, exhibiting typical multinodular pattern. The majority of tumor cells were of clear cell type, although rare epithelioid and spindle cells were also present. Nuclear atypia, mitotic activity of 12 mitoses per 10 microscopic high power fields and Ki-67 labeling index of 20%, as well as three recurrences, corroborated the malignant nature of the tumor. Immunohistochemistry showed positivity for cytokeratin, epithelial membrane antigen, vimentin, S-100 protein and myogenic markers (alpha-smooth muscle actin and muscle-specific actin HHF-35) in keeping with the myoepithelial cell immunophenotype. Staining for CD34, desmin and HMB-45 was negative. Myoepithelial carcinoma should be considered in the differential diagnosis of cutaneous neoplasms composed predominantly of clear cells.

INTRODUCTION: Secondary lactose intolerance (SLI) belongs to the rarer manifestations of gluten-sensitive enteropathy (GSE). It occurs in more severe forms of the disease and its presence contributes significantly to the degree of its expression. OBJECTIVE: The goal of the study was to determine the frequency of SLI in infants with clinically classic form of GSE, as well as its relationship with the duration, severity and age at the diagnosis of the basic disease and the degree of small bowel mucosa damage. METHODS: The study was based on a sample of 42 infants, 30 female and 12 male, aged 7-12 months (x = 9.98 +/- 1.69), with a clinically classic form of GSE. The diagnosis of GSE was established based on the characteristic pathohistological appearance of small bowel mucosa and clinical improvement of patients on gluten-free diet, while SLI on pathological lactose or milk tolerance test. The assessment of basic disease severity was based on body mass divergence in relation to the standard value, as well as on Hb and serum iron levels, while the degree of small bowel mucosa damage was determined according to the modified Marsh criteria. RESULTS: SLI was verified in 8/42 or 19.05% of patients. In addition to the symptoms and clinical signs of GSE, all the patients with SLI also featured the problems characteristic of lactose tolerance disorders, i.e. watery diarrhoea, borborygmus and meteorism occurring after milk meals. In addition, all had perianal erythema (6 with erosive changes), as well as destructive enteropathy (5 subtotal and 3 total). The difference in the duration of the basic disease, age at diagnosis, as well as in the degree of body mass deviation from the standard value between the lactose-tolerant and lactose-intolerant infants was not found. In addition, no difference in Hb and serum iron levels or in the degree of small bowel mucosa damage was found between the two groups. CONCLUSION: Our findings indicate that SLI presents a relatively frequent occurrence in infants with clinically classic GSE, as well as that it occurs independently to the duration, severity and age at diagnosis of the basic disease and the degree of small bowel mucosa damage.

Composite glandular/exocrine-endocrine carcinoma of the gastrointestinal tract is a special tumor type composed of common adenocarcinoma and the neuroendocrine component comprising at least one-third of the whole tumor area. These tumors are rare in the stomach and mostly published as case reports. We describe a further case of a 36-year-old man being unique in that it was associated with extensive formation of sarcoid-like granulomas. Tumor consisted of, predominantly poorly differentiated, intestinal-type adenocarcinoma and poorly differentiated neuroendocrine, small cell carcinoma. The adenocarcinomatous and neuroendocrine areas were separated, but closely juxtaposed with focal areas showing gradual transition from one to another. Perigastric lymph node metastases corresponded either to neuroendocrine or adenocarcinomatous component. On immunohistochemistry, the exocrine part was positive for cytokeratin 7, whereas superficial well-differentiated parts showed positivity with cytokeratin 20 as well. The neuroendocrine component was negative with those two types of cytokeratin. Both adenocarcinomatous and neuroendocrine tumor portions showed carcinoembryonic antigen (CEA) immunoexpression. Neuroendocrine markers (chromogranin A, synaptophysin and neuron-specific enolase) were diffusely positive in the neuroendocrine component, and found only in the scattered cells within the neoplastic glands of the adenocarcinoma. Entire gastric mucosa and all perigastric lymph nodes were extensively affected by noncaseating, sarcoid-like granulomas. The absence of any clinical manifestations combined with the negative results of chest radiograph and laboratory test for the serum angiotensin converting enzyme argued against the possibility of systemic sarcoidosis.

INTRODUCTION: Gluten-free diet (GFD) presents the basis of coeliac disease (CD) treatment. If strictly applied, the disorders of the small bowel mucosa and other disease signs rapidly resolve. OBJECTIVE: The goal of the study was to evaluate the effect of GFD on the growth and nutritional status of children with the classical form of CD. In addition, we analyzed the differences between these parameters with the duration and the patients' compliance with GFD. METHODS: The study goals were achieved on a sample of 90 children, 56 female and 34 male, aged 0.5-7.5 (1.53 +/- 1.05) years, with the classic CD diagnosed on the basis of typical pathohistological findings of the small bowel mucosa and clinical recovery of patients on GFD. The duration of the patients' follow-up was 1.08-8.75 (3.03 +/- 1.14) years, i.e. until the age of 2.5-15 (4.59 +/- 1.78) years. The initial and control values of body height (BH) in relation to matched values for age and gender were expressed in percentiles, while the deviation in body weight (BW) for the matched values of height and gender was expressed in percentages. The referent haemoglobin (Hb) rate in blood, as a laboratory indicator of nutritional status in children aged up to 5 years was > or = 110 g/L, and for those aged above 5 years it was > or = 115 g/L Compliance with GFD was based on the pathohistological findings of the small bowel mucosa or determination of tissue transglutaminase. RESULTS: Over the studied period, the effect of GFD was highly significant, both on the increase of BH percentiles (37.62 +/- 26.26 vs. 57.22 +/- 25.29; p < 0.001), and on the decrease of BW deficit 11.58 +/- 10.80 vs. 0.89 +/- 8.194; p < 0.001). After the treatment period, none of the children showed slowed growth rate or BW deficit above 20%, while BW deviation ranging between 10-20% in relation to the referent values was registered in 17 (18.19%) and the excess of over 20% in 2 patients. In 86 (95.56%) patients, control Hb values in blood were normal, while mild anaemia was registered in 4 patients, all compliant with GFD. The difference between the compliant and non-compliant patients with GFD was not detected either in BH percentiles (p = 0.586) or in BW percentage deviation as compared to standard values (p = 0.516) or in blood Hb values (p = 0.445). In addition, differences between the children on GFD lasting over and below 3 years were not detected either in BH percentiles (p = 0.915) or in BW deviation percentages in relation to the ideal rate (p = 0.476). CONCLUSION: GFD applied for 1-3 years has a highly significant effect on the growth rate and nutritional status of children with the classical form of CD. Significant differences in these parameters of the disease were not detected between strictly compliant and non-compliant patients on GFD.

BACKGROUND/AIMS: Gastrointestinal (GI) diseases are common among patients infected with human immunodeficiency virus (HIV), and may involve the entire GI tract. The aim of the article is to investigate the prevalence of various upper gastrointestinal abnormalities in patients with AIDS. METHODOLOGY: Diagnostic esophago-gastro-duodenoscopy (EGD) was performed in cohort of AIDS patients (total 186) including non-ART, mono and/or dual ART and HAART treated subgroups. Clinical presentation, level of immunosupression and presence of H. pylori infection was also considered. RESULTS: Endoscopic findings included normal (29), esophageal candidiasis (22), esophageal erosions (16), gastritis/duodenitis (135), gastric/duodenal ulcers (7), erosions (6) and infiltration/tumor in the stomach (5). Thirty-nine patients (20.4%) had opportunistic infections/tumors including candida esophagitis, CMV esophagitis, CMV gastritis, gastric non-Hodgkin's lymphoma (NHL) and gastric cryptosporidiosis. H. pylori infection was present in 25.8% of patients, and majority (89.6%) had chronic non-atrophic gastritis. These patients had a higher mean CD4 count compared with H. pylori negative patients (403.5 vs. 226.9 CD4+ cells/microL, p = 0.001). Patients who received HAART had significantly higher frequency of H. pylori infection then non-ART treated patients (p = 0.048). CONCLUSION: Candidiasis was the marker of advanced immunodeficiency, and H. pylori was more common in patients with higher CD4 cell counts on ART, which may suggest that this infection could be an unusual presentation of immune restoration inflammatory syndrome.

INTRODUCTION: Granular cell tumours, relatively uncommon soft tissue tumours, have been a matter of debate among pathologists regarding histogenesis for a long time. Less common locations are in the aerodigestive tract including the oesophagus. CASE OUTLINE: We have recently treated a rare case, a 37-year-old male, who was admitted due to dysphagia and a painful swallow with occasional pharyngo-nasal regurgitation followed with a mild loss of weight. Standard clinical examination including X-ray chest, ECG and laboratory tests did not show pathological findings. Barium contrast oesophagography demonstrated multiple ovoid defects in the wall of the oesophagus. CT scan of the chest confirmed luminal narrowing owing to the tumour of the upper oesophagus. Upper endoscopy showed unusual multifocal nodular lesions alongside the oesophageal axis covered by smooth mucosa. A primary biopsy specimen taken from the largest nodules confirmed an unusual pathological finding of the granular cell tumour. Subtotal, transpleural oesophagectomy was performed and reconstruction was derived by long colon segment interposition through the posterior mediastinum. The postoperative course was uneventful. The operative specimen consisted of four ovoid tumours alongside the oesophagus (the greatest diameter 0.5-1.8, average 1.25). All verified tumours histologicaly consisted of a spindle-shaped or polygonal cells containing small and large eosinophilic granules and central nuclei. Most tumour cells showed strongly positive immunohistochemical staining for S-100 protein. These tumour cells were partially positive for p-53 and Ki-67. No lymph node metastases were detected histologically. CONCLUSION: Multifocal granular cell tumour of the oesophagus is an unusual finding with low incidence, and rarely caused symptoms. Pathological features and multiplicity of such tumours emphasized malignant predisposition requiring surgical resection of the oesophagus.

Pyogenic granuloma (PG), also known as lobular capillary hemangioma, is a benign vascular tumor, most commonly arising on the skin and the oral mucosa. Gastrointestinal localization of PG, except for the oral cavity, is exceptionally rare. We describe a case of ileal PG occurring in a 13-year-old girl, presenting with intestinal obstruction. Histological examination revealed proliferation of capillary-sized vessels, with prominent intravascular component, involving the entire thickness of the intestinal wall. Immunohistochemistry showed positivity for CD31, CD34 and von Willebrand factor, whereas immunostaining for glucose transporter-1 protein (GLUT1) and for human herpes virus 8 (HHV-8) was negative. We suggest that PG should be considered in the differential diagnosis of childhood gastrointestinal polypoid lesions.
