True Ratio

The ratio of males to females with ASD is generally quoted as 4:1 though it is believed that there are biases preventing females being diagnosed and that the true ratio is lower. These biases have not been clearly identified or quantified. Starting with a clinical dataset of 1711 children <18 years old four different methods were employed in an inductive study to identify and quantify the biases and calculate the proportion of females missed. A mathematical model was constructed to compare the findings with current published data. The true male to female ratio appears to be 3:4. Eighty per cent of females remain undiagnosed at age 18 which has serious consequences for the mental health of young women.

e13070 Background: Several studies from India and Pakistan have reported a median younger age of MM diagnosis as compared that of western population. The exact reason for the younger age of myeloma diagnosis in this population is not well understood. Methods: We used the SEER database to analyze age of MM diagnosis in subjects of Indian and Pakistani descent in the United States and compared it to the published data of MM diagnosis in India and Pakistan. Patients with ICD—O-3 morphologic codes (9732/3) and race code 15/16/17 identifying Asian Indians and Pakistanis were identified in the SEER registry data (1973-2013). Data on year of diagnosis, race, sex and age were collected. Four published retrospective studies involving local Indians or Pakistanis patients identified using PUBMED. Average Median age and male to female ratio (M: F) was calculated in both groups and compared for any difference Results: 146 myeloma patients of either Indian or Pakistani descent were identified from the SEER registry. The median age of diagnosis was 67 years with a mean age of 66.1 years. The male to female ratio was 1.41. The retrospective studies analyzed had a total of 495 myeloma patients with median age at diagnosis of 56 years and male to female ratio of 2.01, suggesting that multiple myeloma presented almost a decade earlier in native Indian and Pakistani patients compared to their US counter parts. Conclusions: Subjects in India and Pakistan were significantly younger at the time of MM diagnosis as compared to subjects of Indian and Pakistani descent diagnosed with MM in the US suggesting an environmental factor involved with myeloma genesis in subjects living in India and Pakistan.

Background.To calculate the 1-year prevalence of schizophrenia and related disorders in a catchment area of Malaga (Spain) and determine the prevalence by gender, dwelling (rural or urban) and socioeconomic area (deprived or non-deprived area).Method.This cross-sectional study comprised the mental health area covered by Carlos Haya Hospital. We used multiple large clinical databases and key informants to identify cases.Results.The mean 1-year prevalence of schizophrenia and related disorders was 6.27 per 1000. It was nearly double in men (8.45 per 1000) than in women (4.26 per 1000) (p < 0.001), with a male-to-female ratio of 1.98. The rate was higher in urban (6.64 per 1000) than rural areas (3.95 per 1000) (p < 0.0001) and in socioeconomic deprived areas (7.56 per 1000) than non-deprived areas (6.12 per 1000) (p = 0.005). For the subgroup of schizophrenia, the rates were: men, 5.88 per 1000 and women, 2.2 per 1000 (p < 0.0001), with a male-to-female ratio of 2.67. The rate was also higher in urban (4.2 per 1000) than rural areas (2.49 per 1000) (p < 0.0001) and in socioeconomic deprived areas (4.49 per 1000) than non-deprived areas (3.9 per 1000) (p =0.149).Conclusions.The use of multiple clinical sources of information not only from mental health services, but also from emergency departments, primary care and private settings revealed high prevalence rates of schizophrenia and related disorders. This diagnosis is more common in men and in cities. Such precise estimates of the prevalence of schizophrenia have important repercussions for resource allocation and policy planning.

Background: Nasopharyngeal carcinoma (NPC) is the fourth common cancer in Malaysia. A few studies have looked into the incidence of NPC in Malaysia in general, but there has been no published data on its incidence in Sabah specifically, where NPC is very common among the population. The aim of this study is to present the first report on the incidence of NPC in the state of Sabah, Borneo. Methods: Data of all patients diagnosed with NPC over a 5-year period from January 2015 to December 2019 inclusive were collected from the NPC registry of 3 main hospitals in Sabah. Age-standardized rates (ASRs) for different genders, ethnicities, and districts of origin were calculated. Results: 215 NPC patients were identified with a mean age at diagnosis of 49 (range 9–82). The ASR of NPC was 7.9/100,000 where the average age-adjusted male-to-female ratio was 2.4. The highest ASR was found in Dusun ethnicity in both male (3.19/100,000) and female (1.69/100,000) individuals, followed by Chinese (both genders), and Kadazan (for male individuals) and Bajau (for female individuals). The highest ASR was found in patients originating from Sandakan, Kota Kinabalu, Keningau, and Tawau. Conclusion: This is the first report on the incidence of NPC in Sabah, Borneo. The data suggest high ASRs among the population, especially in male Dusun and Chinese ethnic groups. Further research looking into NPC in this state, especially on risk factors and ways to improve diagnosis and prevention among the population, is recommended.

AbstractWe aimed to compare the demographic, clinical and laboratory characteristics between IgG4-related kidney disease (IgG4-RKD+) and extrarenal IgG4-related disease (IgG4-RKD−) in a large Chinese cohort, as well as describing the radiological and pathological features of IgG4-RKD+. We retrospectively analyzed the medical records of 470 IgG4-related disease (IgG4-RD) patients at Peking University People’s Hospital from January 2004 to January 2020. The demographic, clinical, laboratory, radiological and pathological characteristics between IgG4-RKD+ and IgG4-RKD− were compared. Twenty IgG4-RD patients who had definite etiology of renal impairment including diabetes, hypertension and etc. were excluded. Among the remained 450 IgG4-RD patients, 53 were diagnosed with IgG4-RKD+ . IgG4-RKD+ patients had older age at onset and at diagnosis. Male to female ratio of IgG4-RKD+ patients is significantly higher. In the IgG4-RKD+ group, the most commonly involved organs were salivary gland, lymph nodes and pancreas. It was found that renal function was impaired in approximately 40% of IgG4-RKD+ patients. The most common imaging finding is multiple, often bilateral, hypodense lesions. Male sex, more than three organs involved, and low serum C3 level were risk factors for IgG4-RKD+ in IgG4-RD patients. These findings indicate potential differences in pathogenesis of these two phenotypes.

Abstract Introduction Despite perianal abscess being a common presentation, certain aspects of its management remain controversial, especially the routine use of intra-operative swab cultures. Methods A retrospective review of patients that underwent incision and drainage procedures for a perianal abscess over a six-month period was undertaken. Results Over 6 months, 50 patients were identified. The male to female ratio was 3:1 and median ASA score was 1. Only 6/50 patients presented with recurrent abscess and 1 patient had history of inflammatory bowel disease. On the basis of operative findings, 39 patients (78%) had uncomplicated abscess (not associated with cellulitis, sinus or fistula); swab cultures were performed in 26 (67%) of these patients. All patients were discharged on the same day; microbiology reports did not impact the treatment and no patients were followed up in clinic post-operatively or presented with recurrence. The number of unnecessary microbiology swabs undertaken in this cohort equates to approximately 52 unnecessary swabs a year. The cost of one swab is £10.10p, which means £520 could potentially be saved annually. Conclusion Routine intra-operative swab cultures do not impact management decisions, add to unnecessary costs and therefore should not be undertaken in uncomplicated or first presentation of peri-anal abscesses.

Abstract Background and study aims Dyspepsia is the most common presenting symptom in the gastrointestinal clinic of Mulago National Referral hospital. The etiology is essentially not fully described in our patient population. This study was therefore conducted to establish the causes of dyspepsia based on endoscopic diagnosis among patients with dyspepsia seeking care at the National Referral hospital of Uganda. Patients and methods This retrospective study conducted in the endoscopy unit of Mulago hospital reviewed 356 patient endoscopy reports spanning January 2018 to July 2020 with a focus on those with a referral indication of dyspepsia. Age and sex were the independent variables of interest while the endoscopy findings as reported by the endoscopist were the outcome variable of interest. Results Of the 356 endoscopy reports reviewed, 159 met the inclusion criterion of dyspepsia as the indication. Participant mean age was 47.7 years (± 16.53) with the majority (25.79 %) in the fifth decade while the male to female ratio was 1. The majority of patients had organic dyspepsia (90.57 %) while the commonest finding was gastritis 69 (43.4 %). Gastroesophageal cancers represented (18) 11.32 % of all findings. There was a positive association between age > 50 years with gastroesophageal cancers (7.639) as well as age < 50 years and functional dyspepsia (2.794); however, all these were not statistically significant (P = 0.006 and (P = 0.095, respectively). Conclusions Organic/structural dyspepsia comprises over 90 % of investigated dyspepsia with 11 % comprising cancer among patients seeking endoscopy at the National Referral Hospital of Uganda.

Abstract Background Increasing numbers of children with perinatally acquired HIV (PaHIV) are transitioning into adult care. People living with behaviourally acquired HIV are known to be at more risk of psychosis than uninfected peers. Young adults living with PaHIV face numerous risk factors; biological: lifelong exposure to a neurotrophic virus, antiretroviral medication and immune dysfunction during brain development, and environmental; social deprivation, ethnicity-related discrimination, and migration-related issues. To date, there is little published data on the prevalence of psychotic illness in young people growing up with PaHIV. Methods We conducted a retrospective case note review of all individuals with PaHIV aged over 18 years registered for follow up at a dedicated clinic in the UK (n = 184). Results In total, 12/184 (6.5%), median age 23 years (interquartile range 21–26), had experienced at least one psychotic episode. The presentation and course of the psychotic episodes experienced by our cohort varied from short-lived symptoms to long term illness and nine (75%) appear to have developed a severe and enduring mental illness requiring long term care. Conclusion The prevalence of psychosis in our cohort was clearly above the lifetime prevalence of psychosis in UK individuals aged 16–34 years, which has been reported to be 0.5–1.0%. This highlights the importance of clinical vigilance regarding the mental health of young people growing up with PaHIV and the need to integrate direct access to mental health services within the HIV centres providing medical care.

✓ The authors review 32 cases of spinal cord astrocytoma in patients under 20 years of age who were treated at the Mayo Clinic between 1955 and 1980. There was a 1.3:1 male to female ratio. Twenty patients were between 6 and 15 years of age at the time of diagnosis. The duration of symptoms prior to definitive diagnosis varied from 5 days to 9 years, with an average of 24 months. The most common symptoms were pain (62.5%), gait disturbance (43.7%), numbness (18.8%), and sphincteric dysfunction (18.8%). The most common neurological findings were a Babinski response (50.0%), posterior column sensory dysfunction (40.6%), and paraparesis (37.5%). A median follow-up period of 8.6 years (range 0.8 to 25.5 years) revealed that the survival time diminished with increased histological grade of the astrocytoma (p < 0.001). The development of postlaminectomy spinal deformities represented a serious postoperative complication. This occurred in 13 patients and was first recognized between 8 and 90 months postoperatively. Six deformities occurred following cervical laminectomy, and eight patients required at least one orthopedic procedure. It is crucial to follow these patients for an extended period of time to watch for postoperative spinal deformities.

Introduction. Primary thrombocytosis is very rare in children; reactive thrombocytosis is frequently observed in children with infections, anemia, and many other causes. Aims and Objectives. To identify the etiology of thrombocytosis in children and to analyze platelet indices (MPV, PDW, and PCT) in children with thrombocytosis. Study Design. A prospective observational study. Material and Methods. A total of 1000 patients with thrombocytosis (platelet > 400×109/L) were studied over a period of 2 years. Platelet distribution width (PDW), mean platelet volume (MPV), and plateletcrit (PCT) were noted. Results. Of 1000 patients, 99.8% had secondary thrombocytosis and only two children had primary thrombocytosis (chronic myeloid leukemia and acute myelogenous leukemia, M7). The majority of the children belonged to the age group of 1month to 2 years (39.7%) and male to female ratio was 1.6 : 1. Infection with anemia (48.3%) was the most common cause of secondary thrombocytosis followed by iron deficiency alone (17.2%) and infection alone (16.2%). Respiratory infection (28.3%) was the predominant infectious cause observed. Thrombocytosis was commonly associated with IDA among all causes of anemia and severity of thrombocytosis increased with severity of anemia (P=0.021). With increasing platelet count, there was a decrease in MPV (<0.001). Platelet count and mean PDW among children with infection and anemia were significantly higher than those among children with infection alone and anemia alone. None were observed to have thromboembolic manifestations. Conclusions. Primary thrombocytosis is extremely rare in children than secondary thrombocytosis. Infections in association with anemia are most commonly associated with reactive thrombocytosis and severity of thrombocytosis increases with severity of anemia.
