Coeliac disease and its implications on the oral health of children: A systematic review.

AIM: Apart from various typical gastrointestinal symptoms, coeliac disease may have its clinical manifestations in the oral cavity which is the entrance of the gastrointestinal tract. METHODS: A systematic review of literature was performed using the following databases: Medline, Scopus, EBSCOhost and Cochrane Library for Systematic Review. INCLUSION CRITERIA: observational or experimental original studies published in English with full text available between January 2000 and December 2022, regarding children and adolescents under the age of 20. Risk of bias was determined with the use of Risk Of Bias In Non-randomised Studies of Exposure. RESULTS: Thirty-four studies were included in the review. The analysis confirmed a higher prevalence of numerous oral manifestations in coeliac disease concerning both hard and soft tissues. Our study found the prevalence of dental enamel defects to be at the level of 17.9%-83.5% (P value <0.047) and recurrent aphthous stomatitis of 8.3%-69% (P value <0.039). CONCLUSION: Oral manifestations may precede gastrointestinal symptoms. Patients presenting such manifestations should be screened for coeliac disease. The cooperation of gastroenterologists and dentists could lead to an increased detectability of coeliac disease.

A rare case of primary amenorrhoea and breast development in a 46,XY 15-year-old girl.

A disorder of sex development (DSD) is defined as a congenital condition in which development of chromosomal, gonadal, or anatomical sex is atypical. Swyer syndrome is an example of 46,XY DSD with a female phenotype. It usually becomes apparent in adolescence with delayed puberty and amenorrhoea. Spontaneous breast development is very rare. A 15-year-old girl was presented due to primary amenorrhoea with breast development compatible with Tanner stage V. Hormonal tests revealed hypergonadotropic hypogonadism with low level of oestradiol. Pelvic ultrasound and magnetic resonance imaging revealed a small uterus, and no ovaries were found. In the right lower abdomen, a structure of unknown origin was visible. The chromosome analysis revealed a 46,XY karyotype. The patient was qualified for a laparoscopic bilateral gonadectomy. Postoperative histopathological examination revealed gonadoblastoma. We underline the need to consider DSD 46,XY in the presence of primary amenorrhoea, even when pubertal development is present. Germ cell tumors have a tendency to grow and metastasize rapidly. Delayed diagnosis may increase the risk of malignant transformation and cause a poor diagnosis.

Relationship between water compartments, body composition assessed by bioelectrical impedance analysis and blood pressure in school children.

BACKGROUND: Electrical bioimpedance analysis (BIA) is becoming more widely used in clinical practice as a method of body composition analysis. In healthy children blood pressure (BP) changes with age, body mass and height. Until now the relation between water compartments and BP in healthy children has not been evaluated. The aim of this study was to evaluate the relationship between body composition as well as water compartments (measured by electrical bioimpedance) and BP. METHODS: The study was performed in 72 children (32 girls and 40 boys) aged: 6-7 and 12-13 years. BIA measurements were taken using Nutriguard Data Input device with Bianostic electrodes and following parameters were calculated: total body water (TBW), lean body mass (LBM), fat mass (FM), intra- and extracellular water (ICW, ECW) and phase angle alpha. BP was measured twice using the oscillometric method. RESULTS: Elevated BP > 95th percentile for gender, age and height were observed in 9 children. A significant correlation between systolic (S)BP and TBW (R = 0.4023, p < 0.001), LBM (R = 0.3600, p = 0.002), FM (R = 0.4725, p < 0.001), ECW (R = 0.4598, p < 0.001) and body mass index (BMI) (R = 0.4089, p < 0.001) was found. Furthermore, diastolic (D)BP significantly correlated with TBW (R = 0.3056, p = 0.011), LBM (R = 0.2783, p = 0.021), FM (R = 0.3956, p < 0.001), ECW (R = 0.3869, p = 0.001) and BMI (R = 0.3550, p = 0.002). In the studied group malnutrition (weight < 3rd percentile) was found in 8 children and 2 had obesity (BMI > 95th percentile). Growth disorders were found in 6 children (5 of them being undernourished). CONCLUSIONS: In the studied children SBP and DBP correlated with water compartments, lean body and fat masses derived from BIA. The problem of unrecognized hypertension and malnutrition in children and adolescents is still underestimated in the Polish population.

[Office and 24-hour ambulatory blood pressure measurements in hypertension assessment in children with chronic kidney disease].

Introduction: Hypertension (HT) is one of the major risk factors of chronic kidney disease (CKD) progression and cardiovascular complications. The aim of the study was to analyze blood pressure (BP) values and assess the usefulness of clinical measurements in BP monitoring in children with chronic kidney disease. Material and methods: The study was conducted in 62 children (40 boys and 22 girls) aged 4,2-18,6 years (median age 12.4 (9.1; 16.0) with CKD stages 1 + 2 (n = 9), 3 (n = 17), 4 (n = 15) and 5. Creatinine concentration was measured and glomerular filtration rate was calculated using the Schwartz formula. Each of the patients underwent clinical BP measurements and 24-hour ambulatory blood pressure monitoring (ABPM). Results: Based on clinical meaurements elevated BP values were found in 25 patients (40.3%): in stages 1 + 2 in 33.3%, in stage 3 in 41.2%, in stage 4 in 46.6% and in stage 5 in 38.1% patients. Hypertension was diagnosed with ABPM in 30 patients (48.4% of the studied population): in stages 1 + 2 - 3 patients (33.3%), in stage 3 - 8 patients (47, 1%), in stage 4 - 7 patients (46.7%) and stage 5 - 12 patients (57.1%). Only 12 patients (19.4%) had hypertension diagnosed in both clinical and ABPM measurements. White coat effect was found in 13 children (21.0%) and masked HT in 18 children (29.0%). In 24-hour BP monitoring the highest values of systolic, diastolic and mean BP values were found in children with masked HT. In children with masked HT higher values of 24-hour systolic (120 vs. 105.5 mmHg, p<0.001) and diastolic (75 vs. 65 mmHg, p<0.001) BP compared with clinical values were detected. Children with masked HT had significantly higher nighttime diastolic BP compared with children with HT (1.43 vs. 0.74 z-score, p<0.001). Conclusions: The large percentage of children with masked hypertension is an indication for frequent ABPM measurements in children with chronic kidney diseses. Office measurements are not sufficient to detect HT in children with CKD. The best diagnostic method to confirm and monitor hypertension in patients with CKD is 24-hour ambulatory blood pressure monitoring.

Saliva of obese patients - is it different?

Obesity is a major public health concern that increases the risk of cardiovascular disease, type 2 diabetes and cancer. The incidence of obesity has increased significantly in recent years, not only in adults, but also in adolescents and children. This is evidenced by rapidly developing bariatric surgery, the most effective method of treating morbid obesity. Obesity is a multifactorial disease, and its pathogenesis is not completely understood. Numerous studies have been performed to clarify pathogenetic mechanisms, based mostly on blood and sometimes urine samples. Saliva is easily accessible and can be obtained non-invasively. Our aim was to review studies performed on saliva obtained from obese subjects in order to answer the title question. Obese people have different composition of salivary bacteria. Changes in the concentration of sialic acid, phosphorus and peroxidase activity as well as a lower flow rate of stimulated whole saliva promote dental caries and periodontal disease. Concentrations of salivary uric acid, endocannabinoids and CRP are increased in obesity and may provide a useful index of cardiometabolic risk. Assessment of fasting salivary ghrelin might facilitate choosing the best type of bariatric surgery for a specific patient. A significant decrease in salivary cortisol in women with morbid obesity also seems interesting. There is sufficient evidence to state that the saliva of obese and lean subjects is different. Saliva as an easily accessible research material seems promising, as shown by the few studies performed so far.

The diagnostics of colorectal cancer.

Colorectal cancer (CRC) is one of the most frequent human malignant neoplasms. CRC has an estimated incidence of more than 1,000,000 new cases annually worldwide. Approximately one out of three people who develop CRC dies from the disease. Furthermore, CRC often affects inhabitants of industrialized countries in comparison to less developed countries. Several markers of colon cancer, including CEA, CA-19-9, TPS, TAG-72 and lysosomal hydrolases, have been identified and are now being adopted in routine clinical practice. Increased values of these markers are often the first signal of recurrence or metastases, which is useful in prediction and prognosis of clinical outcome of patients with CRC. Determination of the activity of lysosomal exoglycosidases in body fluids may bring some hope of improving diagnosis of colorectal cancer. However, it has to be remembered that currently the most effective diagnostic method of CRC is endoscopy.
