Pulmonary complications in adults who recovered from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have been reported even in minimally symptomatic patients. In this study, lung ultrasound (LUS) findings and pulmonary function of children who recovered from an asymptomatic or mildly symptomatic SARS-CoV-2 infection were evaluated. We prospectively followed up for at least 30 days patients younger than 18 years who recovered from SARS-CoV-2 infection at the Fondazione IRCCS Ca' Granda Ospedale Maggiore Policlinico, Milan (Italy). All enrolled patients underwent LUS. Airway resistance measured by the interrupter technique test was assessed in subjects aged 4–6 years, whereas forced spirometry and measurement of diffusing capacity of the lungs for carbon monoxide were performed in subjects older than 6 years. To evaluate a possible correlation between pulmonary alterations and immune response to SARS-CoV-2, two semiquantitative enzyme immune assays were used. We enrolled 16 out of 23 eligible children. The median age of enrolled subjects was 7.5 (0.5–10.5) years, with a male to female ratio of 1.7. No subject presented any abnormality on LUS, airway resistance test, forced spirometry, and diffusing capacity of the lungs for carbon monoxide. On the other hand, all subjects presented Ig G against SARS-CoV-2. In contrast in adults, we did not detect any pulmonary complications in our cohort. These preliminary observations suggest that children with an asymptomatic or mildly symptomatic SARS-CoV-2 infection might be less prone to develop pulmonary complications than adults.

Objective:To study suicides occurring in Ballarat with regard to incidence, demographic variables, possible causal factors, and association with psychiatric disorders over a period of 5 years. Method:A detailed review of the coroner's record of every suicide occurring during 1992-1996 was undertaken. Information was obtained on socio-demographic variables, method and circumstances of suicide, and associated psychiatric disorders in each case and subjected to psychological autopsy. Results:75 suicides were recorded. The male to female ratio was 4:1 and average age was 43 years. 60% had associated psychiatric illnesses, mainly affective disorders. Carbon monoxide self-poisoning accounted for 40%, firearms for 30%, and hanging, overdose, asphyxia and other methods for the remaining 30%. It was statistically significant that the younger age group preferred firearms to other methods, and that their suicides were precipitated by interpersonal conflicts. Social and personal difficulties were associated in 33%, and triggering factors were present in 40%. Previous suicide attempts were present in 28%, while 32% had manifest behavior changes preceding suicides or verbalized their intent to suicide. Conclusions:Suicide rates in Ballarat were higher than the average overall Victorian and Australian rates. After a consistent decline over 4 years an increase occurred in 1996. The preferred method of suicide was carbon monoxide, although the young preferred firearms. Demographic and other psychosocial factors were similar to the rest of Australia. Unemployment was not a significant factor. Psychiatric conditions, personal and social problems figured prominently as factors of etiological significance in suicide subjects.

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.

Ventilation Heterogeneity

It has long been assumed that the ventilation heterogeneity associated with lung disease could, in itself, affect the measurement of carbon monoxide transfer factor. The aim of this study was to investigate the potential estimation errors of carbon monoxide diffusing capacity (DlCO) measurement that are specifically due to conductive ventilation heterogeneity, i.e., due to a combination of ventilation heterogeneity and flow asynchrony between lung units larger than acini. We induced conductive airway ventilation heterogeneity in 35 never-smoker normal subjects by histamine provocation and related the resulting changes in conductive ventilation heterogeneity (derived from the multiple-breath washout test) to corresponding changes in diffusing capacity, alveolar volume, and inspired vital capacity (derived from the single-breath DlCO method). Average conductive ventilation heterogeneity doubled ( P < 0.001), whereas DlCO decreased by 6% ( P < 0.001), with no correlation between individual data ( P > 0.1). Average inspired vital capacity and alveolar volume both decreased significantly by, respectively, 6 and 3%, and the individual changes in alveolar volume and in conductive ventilation heterogeneity were correlated ( r = −0.46; P = 0.006). These findings can be brought in agreement with recent modeling work, where specific ventilation heterogeneity resulting from different distributions of either inspired volume or end-expiratory lung volume have been shown to affect DlCO estimation errors in opposite ways. Even in the presence of flow asynchrony, these errors appear to largely cancel out in our experimental situation of histamine-induced conductive ventilation heterogeneity. Finally, we also predicted which alternative combination of specific ventilation heterogeneity and flow asynchrony could affect DlCO estimate in a more substantial fashion in diseased lungs, irrespective of any diffusion-dependent effects.

To study the effects of exercise on pulmonary diffusing capacity, we measured the lungs' diffusing capacity for carbon monoxide (DLCO) during exhalation from 30 to 45% exhaled vital capacity in eight healthy subjects at rest and during exercise while both sitting and supine. We found that DLCO at these lung volumes in resting subjects was 26.3 +/- 3.2% (mean +/- SE) higher in the supine than in the sitting position (P less than 0.001). We also found that, in both positions, DLCO at these lung volumes increased significantly (P less than 0.001) with increasing exercise and approached similar values at maximal exercise. The pattern of increase in DLCO with an increase in oxygen consumption in both positions was curvilinear in that the rate of increase in DLCO during mild exercise was greater than the rate of increase in DLCO during heavy exercise (P = 0.02). Furthermore, in the supine position during exercise, it appeared that DLCO reached a physiological maximum.

✓ 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.
