Equity analysis audit of access and utilisation of Special Care Dental Services by ethnicity and social demographic markers

OBJECTIVE

To identify and investigate any differences in utilisation of the, Sussex Community NHSFT, Special Care Dental Service (SCDS) across multiple demographic factors, including ethnicity, socio-economic groups and age in the Crawley area.

METHOD

Data were audited for all new patients seen at the Crawley Special Care Dental Centre from November 2020-October 2021. Demographic data were compared to population data from the 2011 Census. Deprivation data, using Index of Multiple Deprivation, were also examined against utilisation and failure to attend appointments.

RESULTS

A total of 1250 new patients accessed the Crawley SCDS between November 2020 and October 2021. The data suggests good equity to the service being utilised by the local community; the proportions of patients utilising the service over the course of a year from different ethnic groups reflected the demographic profile of Crawley. The proportion of failed appointments showed no correlation with deprivation decile. There was also no association between ethnic group and proportion of failed appointments.

CONCLUSION

Ensuring equal utilisation of healthcare for all population groups has become a priority for healthcare providers. This audit found minimal inequities in utilisation of the Special Care Dental Service at Crawley.

Active surveillance or radical prostatectomy? Which treatment is best?

OBJECTIVE

We evaluated the patients who are candidates for active surveillance and treated with radical prostatectomy. These patients were compared with other patients who had not met the criteria of active surveillance.

METHODS

In total, 135 patients were included in the study. The patients were divided into two groups. The patients in Group 1 had less than three positive cores, Gleason 6 (3 + 3) and PSA level equal to or less than 10 ng/ml. Patients in Group 2 had three or more positive cores, Gleason 6 (3 + 3) and PSA level equal to or higher than 10 ng/ml. Pathological results of each groups were compared.

RESULTS

The patients' ages were between 52 and 76, and 50 and 77 in groups 1 and 2, retrospectively. There were 69 and 66 patients in groups 1 and 2, retrospectively. The mean age of patients, PSA levels, PSA density, and prostate volumes were 63.89 ± 5.89 years, 5.82 ± 1.84 ng/ml, 0.14 ± 0.07 and 51.21 ± 31.75 cc (Group 1) and 65.77 ± 6.36 years, 13.65 ± 17.11 ng/ml, 0.63 ± 1.03 and 45.44 ± 26.77 cc (Group 2). T2a, T2c, T3a and T3b were reported in 28 patients, 36 patients, 3 patients and 2 patients after pathological evaluation in Group 1,respectively. T2a, T2c, T3a and T3b were reported in 13 patients, 47 patients, 5 patients and 1 patient in the other group, respectively.

CONCLUSION

The final pathology showed that there is no difference in the positive surgical margin, proportion of insignificant prostate cancer and Gleason upgrading between groups. The clinicians must be aware of the fact that active surveillance can be misdiagnosed in some patients (Tab. 2, Ref. 20).

Immediate adverse reactions to intravenous immunoglobulin in children: a single center experience

Intravenous immunoglobulin (IVIG) is commonly used in primary and secondary immunodeficiency diseases as well as autoimmune conditions as immunomodulatator treatment. Immediate adverse events which are generally mild and occur during infusion are seen in 6 hours. Reported immediate adverse events are in a wide range from 1%-40% in pediatric patients. 115 patients who received IVIG (except newborns) were included into this crosssectional study. IVIG was given to patients for primary immunodeficiencies (n=8), ITP (n=65), Kawasaki disease (n=11), secondary immunosupression (n=28), and passive immunization (n=3). 5%, 10% IVIG preparations and pentaglobin were used. Headache, fever, chills, nausea, rash, arthralgia, myalgia and back pain were accepted as mild immediate events. There were 62 (54%) boys and 53 (46%) girls aged 1 month-18 years. Mean age of the group was 7.4±4.6 years. Immediate adverse events due to IVIG infusions were seen in 29 (25.2%) of all patients. Gender and types of the disease were not different in significance regarding the presence of adverse events. The rate of adverse events did not change with receiving pre-medication. The most common reaction was fever/chills. Immediate reactions were seen in first 6 hours in 7 patients and during infusion in the remaining. They were treated with slowing of the infusion rate and infusion was stopped in 3 patients because of moderate events. Because of the increasingly use of IVIG therapy, it is important to know the side effects. High doses, high infusion rates, accompanying infection may worsen the adverse effects especially in primary immunodeficiency diseases.

Plasma amino acid profile in autism spectrum disorder (ASD)

OBJECTIVE

In our study, we aimed to reveal pathophysiologic mechanisms in ASD by comparing plasma amino acid levels between patients and healthy controls while considering vitamin B12 and D levels.

PATIENTS AND METHODS

The study included 21 patients aged 2-18 years-old who were followed with a diagnosis autism spectrum disorder (ASD) and 21 age and sex-matched healthy children from our outpatient clinic as control group.

RESULTS

The study included 42 children and adolescents aged 2-18 years-old (19 girls and 23 boys). There were no significant differences in terms of body weight and height between the groups. We found significant differences in levels of ammonium, phosphoethanolamine, histidine, homocysteine, carnosine, methionine, cystathionine, cystine, threonine, 3-methyl histidine and phenylalanine/tyrosine ratio between patient and control groups. Both vitamin B12 and D were significantly lower in the ASD group compared to controls. In the variance analysis with vitamin B12 and D as covariates, significant differences persisted for only phosphoethanolamine (p=0.04), cystathionine (p<0.001), cystine (p=0.006) and threonine (p=0.02).

CONCLUSIONS

Further studies are needed on the amino acids that show variations in children with ASD in order to reveal their role in the etiology and therapeutic use in ASD.

Role of circulating nesfatin-1 in the underweight children with poor appetite

OBJECTIVE

To investigate serum concentration of nesfatin-1 in underweight children who have poor appetite, and its association with anthropometric markers of malnutrition.

PATIENTS AND METHODS

We recruited 50 underweight children and adolescents (aged 2-18 years) who presented with loss of appetite. Thirty age- and sex-matched controls were also included in the study. Fasting serum nesfatin-1 concentrations were measured by using Enzyme-Linked Immunosorbent Assay (ELISA) technique.

RESULTS

Mean nesfatin-1 level was significantly higher in underweight children when compared to controls (p<0.001). There was no correlation between serum nesfatin-1 levels and anthropometrics markers.

CONCLUSIONS

Our results suggest that nesfatin-1 might have an important role in regulation of food intake and pathogenesis of loss of appetite in children.

MEGALENCEPHALY, POLYMICROGYRIA, POLYDACTYLY AND HYDROCEPHALUS (MPPH) SYNDROME: A NEW CASE WITH OCCIPITAL ENCEPHALOCELE AND CLEFT PALATE

The megalencephaly, polymicrogyria, polydactyly, and hydrocephalus (MPPH) syndrome is quite rarely seen. The four main findings in this syndrome may be accompanied by severe psychomotor retardation, blindness, hypotonia, convulsions, and facial dysmorphism. In this paper, we present a female newborn at 39 weeks gestational age born to parents who are first degree cousins. Beside the facial dysmorphism and four main features of the MPPH syndrome, the findings on the physical examination of the patient were, hypertonicity, occipital encephalocele, cleft palate, and multiple polyps in the tongue. The presence of occipital encephalocele, cleft palate, and polyps in the tongue in this patient was not reported previously in the literature.

A male newborn with Simpson-Golabi-Behmel syndrome, presenting with metopic synostosis, anal atresia, and total anomalous pulmonary venous return

Simpson-Golabi-Behmel syndrome is a clinical condition described by Simpson, characterized with multiple congenital anomalies and caused by Glypican 3 (GPC3) mutations of the X-linked gene. Typical findings such as overgrowth, hypoplastic changes of hands and feet, visceromegaly, cleft palate and macrocephalic distinctive facial features and multiple organ anomalies might be observed. GPC3 mutation is claimed to generally cause metopic synostosis. This case was reported because even though a lot of anomalies accompanying Simpson-Golabi-Behmel syndrome had been noticed, combination of metopic synostosis, has not been reported before.

A study on the effects of pica and iron-deficiency anemia on oxidative stress, antioxidant capacity and trace elements

Pica is defined as developmentally inappropriate consumption of nonnutritive substances for at least 1 month. There are a few studies on serum trace element levels of patients with pica. The literature contains contracting data on the levels of oxidative stress and antioxidant levels in patients with iron-deficiency anemia (IDA). The effect of pica on oxidative stress and antioxidant capacity has not been investigated yet. The present study evaluated the effects of pica and IDA on oxidative stress and antioxidant capacity as well as on the levels of trace elements including serum zinc and selenium in 47 children with IDA plus pica, 22 children with IDA only and 21 nonanemic children as controls. The results demonstrated significantly lower levels of serum selenium and zinc in pica and IDA groups compared to the control group. Total oxidant levels were highest in the pica group and consistently, the lowest total antioxidant capacity was observed again in the pica group. Comparison of pica and IDA groups yielded significantly lower levels of total antioxidant levels and significantly higher oxidative stress index in the pica group. Consequently, it is thought that the detrimental effects of pica within the organism were mediated by adverse impacts on antioxidant capacity and oxidative stress. These effects should be kept in mind while managing patients with pica.

Association between polymorphisms of folate- and methionine-metabolizing enzymes and susceptibility to malignant lymphoma

Genetic alteration is considered a probable cause of malignant lymphoma. Folate and methionine metabolism play essential roles in DNA synthesis and DNA methylation, and their metabolic pathways might thus affect disease susceptibility. In the present study, 2 polymorphisms were evaluated for a folate metabolic enzyme, methylenetetrahydrofolate reductase (MTHFR), and one was evaluated for methionine synthase (MS). The 2 polymorphisms, MTHFR677 C-->T and MTHFR1298 A-->C, are reported to reduce the enzyme activity, which causes intracellular accumulation of 5,10-methylenetetrahydrofolate and results in a reduced incidence of DNA double-strand breakage. The MS2756 A-->G polymorphism also reduces the enzyme activity and results in the hypomethylation of DNA. To evaluate the association between malignant lymphoma susceptibility and these polymorphisms, hospital-based case-control study was conducted in Aichi Cancer Center. Ninety-eight patients with histologically confirmed lymphoma and 243 control subjects without cancer were evaluated. Unconditional logistic regression analyses revealed a higher susceptibility with the MTHFR677 CC and the MTHFR1298 AA genotypes (odds ratio, 2.26; 95% confidence interval, 1.26-4.02) when those harboring at least one variant allele in either polymorphism of MTHFR were defined as the reference. For the MS polymorphism, the MS2756 GG genotype also showed a higher susceptibility (odds ratio, 3.83; 95% CI, 1.21-12.1) than those with MS2756 AA or AG types. The significance was not altered when these 3 polymorphisms were evaluated in combination, and the results suggest that folate and methionine metabolism play important roles in the occurrence of malignant lymphomas. Further studies to confirm the association and detailed biologic mechanisms are now required.

Which patients with hepatitis C develop liver complications?

To identify variables that are independent predictors of adverse outcomes in chronic hepatitis C, we analyzed a cohort of 455 patients followed for a median of 4.7 years. Associations were sought between demographic and behavioral factors, hepatitis C virus (HCV) genotype, liver histology and liver tests at entry, and development of liver complications, hepatocellular carcinoma (HCC), hepatic transplantation and liver-related death. Independent predictors were identified by multivariate analysis. The following were associated with a significantly higher rate of liver complications: age; birth in Asia, Europe, Mediterranean region, or Egypt; transmission by blood transfusion or sporadic cases; HCV genotypes 1b and 4 (compared with 1/1a); fibrosis stage 3 or 4 (cirrhosis); serum albumin; bilirubin; prothrombin time; and alpha-fetoprotein. However, the only independent predictors of liver-related complications were sporadic transmission (P <.001), advanced fibrosis (P =.004), and low albumin (P <.001). The corresponding independent risk factors for HCC were male gender (P =. 07), sporadic transmission (P <.001), and albumin (P <.001); bilirubin (P =.02) was an additional predictor of transplantation or liver-related death. It is concluded that only patients with advanced hepatic fibrosis or cirrhosis, are at risk of developing hepatic complications of chronic hepatitis C during 5-year follow-up. Among such patients, abnormalities in serum albumin, bilirubin, or prothrombin time indicate a high probability of complications. Patients without definite risk factors for HCV (sporadic cases) are at higher risk of complications, possibly because of interaction between older age, duration of infection, country of birth, and HCV genotypes 1b and 4.

Endometrial cytology in postmenopausal hormone replacement therapy

Endometrial changes is postmenopausal hormone replacement therapy (HRT) were studied by comparing cytological and histological findings. Cytological and histological examinations were conducted on 138 benign cases and 26 abnormal cases, including 24 cases with disordered proliferative phase (DOP) and 2 cases with simple endometrial hyperplasia (SEH), for a total of 164 cases. Hormones were administered as follows: 1) single cyclic administration of estrogen only (Single-HRT) for 31 cases, 2) cyclic administration of estrogen and progestin (Cyclic-HRT) for 105 cases, and 3) continuous administration of estrogen and progestin (Continuous-HRT) for 28 cases. All of the 164 cases were studied cytologically as to shape, appearance, nuclear number on maximum diameter, and so on. The benign cases in each mode of administration as described above revealed the following: 1) Single-HRT, atrophy or the proliferative phase was noted histologically, and the copresence of the endometrial epithelium and the ciliated cell metaplasia was observed cytologically; 2) Cyclic-HRT, the first half of the administration term was of the proliferative phase histologically, and the linear and long glands were seen cytologically. In the latter half of the administration term the secretory phase was noted histologically and the curved/linear glands with subnuclear vacuolization were observed cytologically; and 3) Continuous-HRT, atrophy was noted histologically, and fewer glands and atrophic cells on the endometrial epithelium with wrinkles mixed therein were seen cytologically. On the other hand, cytological examinations of the abnormal cases revealed a mean average of 35 nuclei on the maximum diameter of the gland, protrusion and/or ramification of the glands, densely clustered glands, and back-to-back glands without fusion, as well as irregularly dilated tortuous glands in SEH. These abnormal findings were considered useful for early detection of endometrial disorders in the hormone replacement therapy by cytodiagnosis.

Molecular epidemiology of hepatitis C in Australia

The aim of this study was to determine the distribution of hepatitis C virus (HCV) genotypes in Australian patients with hepatitis C and to identify factors associated with particular genotypes. Serum isolates of HCV-RNA were genotyped using a commercial oligonucleotide hybridization (line probe) assay. Relationships between demographic factors, mode of HCV transmission and HCV genotype were assessed by logistic regression analysis. Among 463 patients with hepatitis C, 425 tested positive for HCV-RNA and a single HCV genotype was identified in 420 cases. The patients' places of birth were Australia or New Zealand (62%), Asia (13%), Europe (12%), Mediterranean (6%), Middle East (6%) and other countries (< 1%). The most common genotypes were type 1 (52%) or type 3 (32%); type 2 (9.3%), type 4 (5.5%) and type 6 (1.7%) were less common. Patients with genotype 1b were older (48 +/- 13 years, P< 0.001) and patients with genotype 3 were younger than the remaining patients (37 +/- 11 years vs 42 +/- 12 years, P< 0.001). Among type 1 isolates, 1b was more common for patients born outside Australia compared with those born in Australia (50% vs 13%, P< 0.001) whereas non-1b subtypes were more common among Australian-born patients. Likewise, 21 of 23 (91%) patients with type 4 were from Egypt and six of seven (86%) with type 6 were from Vietnam. The relative importance of parenteral risk factors for HCV also varied according to geographic origin. Thus, a definite risk factor for HCV acquisition was identified in > 95% of Australian-born patients, but in only 33% of Asian or Mediterranean-born patients. Logistic regression analysis indicated that region of birth and risk factor (intravenous drug use or not) would allow 98% of type 4 cases and 76% of type 1b cases to be identified correctly. In summary, region of birth, patterns of migration over time and risk factors for transmission of HCV interact to determine the distribution of HCV genotypes in a multi-racial community like Australia.

Effects of hepatitis G virus coinfection on severity of hepatitis C: relationship to risk factors and response to interferon treatment

The aims of the present study were to identify characteristics that are more often associated with hepatitis G virus (HGV) coinfection in Australian patients infected with the hepatitis C virus (HCV) and to investigate the effects of HGV on the histological and functional severity of chronic hepatitis C. Serum samples from 209 patients with chronic hepatitis C were tested for HGV-RNA using single-round reverse transcriptase-polymerase chain reaction to primers directed at the NS5 region of the HGV genome. Hepatitis G virus RNA was detected in 40 cases (19%). Hepatitis G virus-coinfected patients tended to be younger and parenteral risks could be identified in all but six. Although country of birth did not differ significantly between the coinfected and HCV-alone groups, HGV-positive patients appeared to be less likely to have originated from Asia. On logistic regression analysis, HCV genotype 3a was found in a significantly higher proportion of patients with HGV coinfection than other genotypes (P < 0.01). Liver histology and response to interferon were similar in the HGV-coinfected and HCV-alone groups and liver-related complications appeared to occur less frequently in patients with both HGV and HCV. On univariate analysis, antipyrine clearance was found to be higher in the coinfected group (P < 0.05), implying better preservation of hepatic metabolic function, but this difference was lost when adjusted for HCV genotype. In conclusion, coinfection with HGV was more commonly associated with HCV genotype 3a, a genotype associated with injection drug use in younger patients. However, the presence of HGV coinfection did not adversely affect liver disease or the response to interferon treatment in patients with chronic hepatitis C.

The lesion causing continuous facial myokymia in multiple sclerosis

OBJECTIVE

To attempt to identify the site of the lesion causing continuous facial myokymia (CFM) in multiple sclerosis (MS) through the use of magnetic resonance imaging (MRI).

DESIGN

A case series was employed.

SETTING

The Baird Multiple Sclerosis Center, Millard Fillmore Hospital, and the Neurology Department, Buffalo General Hospital, Buffalo, NY.

PARTICIPANTS AND MEASURES

Twelve patients with MS and CFM were examined by MRI of the brain while the CFM was present. The MRI examinations were also performed before the CFM had developed and after it had ceased in eight of the patients. Another 57 patients with MS who never had CFM but who had similar disabilities to those who did were also examined by MRI.

RESULTS

In 11 of the 12 patients with MS and CFM, the causative lesion was demonstrated to involve the postnuclear, postgenu portion of the facial nerve intraaxially in the dorsolateral pontine tegmentum ipsilateral to the CFM. In the majority of patients who were studied after the CFM had stopped clinically, the lesion was observed to resolve on MRI. Seventeen percent of the patients with MS but without CFM were found to have the typical pontine tegmental lesion.

CONCLUSIONS

Continuous facial myokymia in MS is caused by a pontine tegmental lesion involving the postnuclear, postgenu portion of the facial nerve. The lesion is identified by MRI in approximately 90% of patients with MS who have CFM clinically. The typical MRI lesion may also be found in a minority of patients with MS who do not have CFM clinically.

Imprint cytology of low-grade B-cell lymphoma of mucosa-associated lymphoid tissue arising in the thymus: a case report

Low-grade B-cell lymphoma of mucosa-associated lymphoid tissue (MALT) arising in the thymus is a very rare tumor with characteristic morphologic features. We describe a case of thymic low-grade B-cell MALT lymphoma occurring in a 59-yr-old woman with Sjögren's syndrome, in whom the definite diagnosis was difficult at the time of surgery. An immunohistologic and genotypic study, however, was diagnostic of lymphoma. A review of cytologic material was undertaken, and it was felt that the cytologic features in Giemsa-stained preparations in imprint smears were present that initially should have enabled the correct cytodiagnosis and distinction from the other thymic lesions. The findings presented in this study were considered to contribute to the cytodiagnosis of a thymic lesion, which might, in the past, have been erroneously interpreted as another lymphoproliferative disorder.

Circulating CD3+ CD4+ CD8+ T lymphocytes in multiple sclerosis

Triple-antibody flow cytometry was used to search for distinctive populations of peripheral blood lymphocyte immunophenotypes in multiple sclerosis (MS). Using monoclonal antibodies to the cell surface markers CD3, CD4, and CD8, T cell subsets were quantified on a cohort of 31 MS patients (not treated with corticosteroids for at least 6 months), 30 healthy donors, and 14 patients with other autoimmune diseases (also corticosteroid treatment-free for at least 6 months). Untreated MS patients displayed a significantly greater population of CD3+CD4+CD8+ circulating T cells than healthy donors (P = 0.023). Patients with other autoimmune diseases displayed mean populations of CD3+CD4+CD8+ cells greater than normal donors and less than MS, but not significantly different from either. An additional 45 MS patients who had received corticosteroid therapy within the previous 6 months were phenotyped. Treatment of symptomatic MS with corticosteroids was associated with a smaller population of circulating CD3+CD4+CD8+ cells. Some MS patients have significantly greater numbers of peripheral blood T lymphocytes simultaneously expressing CD3, CD4, and CD8 surface markers than healthy donors and this population of cells may be reduced by corticosteroids treatment. This triple positive phenotype may be a manifestation of a systemic immune abnormality in MS.

[Morphometrical study on prognosis of stage I pulmonary adenocarcinoma]

The prognostic significance of morphometry in stage I pulmonary adenocarcinoma had been examined in Papanicolaou-stained bronchial brushings, using an image analyzer. The data of long-term survivors (LTS), alive for more than 5 years, and short-term survivors (STS), who had died within 5 years, were compared. LTS were found to have a smaller nuclear area, a shorter nuclear perimeter, and a smaller nucleolar area than those of the STS. The nuclear size is considered important in any histological subtypes. The variation index of the nuclear area, the nuclear circularity, and the number of nucleoli did not differ between the two groups. These results would seem to be useful in determining the prognosis and the indication type of adjuvant therapy to be used in surgical operations.

[Malaria and pregnancy. Epidemiological situation in Kinshasa (Zaïre)]

By regular blood smears to 730 women (430 pregnant women and 250 non pregnant) authors state precisely epidemiologic situation of malaria to women at Kinshasa. The prevalence of malaria of pregnant women is 22 per cent against 6.1 per cent for non pregnant adult women. Malarial infestation in gravido-puerperal period is : mother : 23.7 per cent ; umbilical cord : 3.1 per cent ; newborn : 5.4 per cent ; placenta : 10.1 per cent. Plasmodium falciparum is the principal agent of malaria at Kinshasa. Neither age, nor parity constitute risk factors of malaria. Many cases of malaria without fever exist at Kinshasa. Newborn with malaria and from pregnancies with infected placentas present at the birth a small weight. Placentas of pregnancies with malaria and infected have invariably the same weight.
