Impact of anxiety,stress and depression related to COVID-19 pandemic on the course of hereditary angioedema with C1-inhibitor deficiency

Background

Hereditary angioedema (HAE) attacks can be provoked with psychological factors. The aim of this study was to assess the effects of anxiety, depression and stress related to COVID-19 pandemic on disease activity of HAE patients during the quarantine period (QP) and the return to normal period (RTNP).

Methods

This study was conducted between March 2020 and September 2020 in four allergy centres. Demographic, clinical features and mental health status were evaluated in QP (from March to the beginning of June) and RTNP (from June to the beginning of September) applied by the government. The 10-point visual analogue scale (VAS10) was used to define the severity of HAE attacks. Depression, Anxiety and Stress Scales-21 (DASS-21) and Fear of COVID-19 (FC-19) scale were performed to assess mental health status.

Results

139 HAE patients were included in the study. In QP, median attack numbers and median VAS10 scores were 5 (min-max: 0–45) and 6 (min-max: 0–10), respectively. HAE attack numbers, DASS-21 stress, anxiety, depression and total DASS-21 scores, and FC-19 scores were higher in QP than RTNP (p = 0.001, p < 0.001, p = 0.001, p < 0.001, p < 0.001, p < 0.001, respectively). However, there was no difference in attack severity scores between the two periods (p > 0.05).

Conclusions

This study revealed that the restriction measures during COVID-19 outbreak cause an increase in the number of HAE attacks in relation to anxiety, depression, stress and fear of COVID-19 pandemic. Therefore, it is important to provide psychological support to HAE patients during the pandemic.

     

Pulmonary contusions in patients with rib fractures: The need to better classify a common injury

BackgroundPulmonary contusions are common injuries. Computed tomography reveals vast contused lung volume spectrum, yet pulmonary contusions are defined dichotomously (unilateral vs bilateral). We assessed whether there is stepwise increased risk of pulmonary complications among patients without, with unilateral, and with bilateral pulmonary contusion.MethodsWe identified adults admitted with rib fractures using the largest US inpatient database. After propensity-score-matching patients without vs with unilateral vs bilateral pulmonary contusions and adjusting for residual confounders, we compared risk for pneumonia, ventilator-associated pneumonia (VAP), respiratory failure, intubation, and mortality.ResultsAmong 148,140 encounters of adults with multiple rib fractures, 19% had concomitant pulmonary contusions. Matched patients with pulmonary contusions had increased risk of pneumonia 19% [95%CI:16–33%], respiratory failure 40% [95%CI: 31–50%], and intubation 46% [95%CI: 33–61%]. Delineation showed bilateral contusions, not unilateral contusions, attributed to increased risk of complications.ConclusionsThere is likely a correlation between contused lung volume and risk of pulmonary complications; dichotomously classifying pulmonary contusions is insufficient. Better understanding this correlation requires establishing the clinically significant contusion volume and a correspondingly refined classification system.     

Dystopic neurohypophysis

A dystopic neurohypophysis was noted incidentally at autopsy in a 51 -year-old man with no endocrine abnormality. The dystopic gland was situated in the upper region of the tuber cinereum and macroscopically simulated a neoplasm. The pituitary fossa contained only anterior hypophyseal elements. Review of the literature disclosed 19 such cases discovered at autopsy; 11 occurred in normal individuals with no endocrine abnormality. Radiological study revealed 145 additional cases. Except for the 6 occurrences described in normal individuals, the rest occurred in patients with anterior pituitary dysfunction. No instance of isolated diabetes insipidus has been reported due to dystopia of the neurohypophysis. Dystopia of the neurohypophysis in normal individuals should be distinguished from those occurring in patients with anterior pituitary abnormalities. The former represent a true dystopia and are not associated with perinatal injury, in contrast to the latter, which are acquired dystopias secondary to regeneration of the neurohypophysis and are associated with perinatal injury. Although anterior and posterior pituitary glands are formed by appositional growth, their development and functional status are entirely independent. Finally, the most significant clinical feature of dystopic neurohypophysis is the absence of any related symptoms and this condition should always be considered in the clinical differential diagnosis of hypothalamic lesions. In such patients, a surgical procedure may be avoided because other hypothalamic lesions, such as hamartomas and astrocytomas, are more frequently symptomatic.     

Retinal tears associated with panuveitis and Behçet's disease

To report retinal tears formation in 3 eyes of 2 patients with active panuveitis and Beh?et's disease. We describe 2 patients that were diagnosed and treated for Beh?et's disease with active panuveitis. Retinal tears developed while the inflammation was active. The patients were treated with topical, oral steroids, and cyclosporine therapy for bilateral panuveitis. One patient presented with a retinal tear located at the periphery of the active retinal lesion. The other had multiple tears associated with active retinal lesions in both eyes. Argon laser photocoagulation was performed in both patients as soon as the tears were detected. Ocular inflammation was controlled with this therapy, and only a few mild flare-ups occurred. The patients have been followed up for 8 and 16 months, respectively. During this period no new retinal tears have developed. Although retinal tear formation is rarely associated with Beh?et's panuveitis, the clinician should be aware of this as a possible complication. When structural changes are present in the vitreous, detailed ophthalmoscopy is indicated to assess for retinal tears. If a tear is detected in a patient with panuveitis and Beh?et's disease, laser photocoagulation therapy should be performed immediately to prevent retinal detachment.     

Lipoprotein levels in patients with pregnancy induced hypertension

The purpose of this prospective study was to investigate the levels of Lp(a), Apo(a), VLDL, LDL and HDL in 23 patients with pregnancy induced hypertension (PIH) and in 20 control. The Mann-Whitney U tests was used for comparisons between the two groups. Serum Lp(a) and Apo(a) levels were sigificantly raise in the PIH group (p < 0.05 andp < 0.05 respectively) and no significant correlations could be demonstrated for other lipoproteins.     

The Efficacy of Fluoxetine in the Treatment of Premature Ejaculation: A Double-Blind Placebo Controlled Study

Purpose

The efficacy of the selective serotonin re-uptake inhibitor fluoxetine in the treatment of premature ejaculation was examined.

Materials and Methods

The study comprised 17 patients with premature ejaculation who presented to the urology clinic of our medical school. In this double-blind study the patients were randomized into treatment groups receiving 20 mg. fluoxetine daily for 1 week and 40 mg. daily afterward (group 1) or 1 capsule placebo daily for 1 week and 2 capsules daily afterward (group 2). The groups were evaluated according to the latent period of intravaginal ejaculation.

Results

The latent period of intravaginal ejaculation in group 1 was significantly longer than that in group 2. Nausea, headache and insomnia were reported side effects.

Conclusions

Fluoxetine may be regarded as a safe and effective alternative in the treatment of premature ejaculation.     

Effect of aluminum adjuvants on safety and immunogenicity of Haemophilus influenzae type b-CRM197 conjugate vaccine

OBJECTIVE: The present study was carried out to evaluate the safety and immunogenicity of the Haemophilus influenzae type b-CRM197 (Hib-CRM197) conjugate vaccine in relation to the change of adjuvant from aluminum hydroxide to aluminum phosphate (AlPO4). METHODS: The present study was a clinical phase II, observer-blind, randomized, multicenter, controlled study. Subjects were healthy infants aged 6-12 weeks, eligible for expanded program of immunization (EPI) routine vaccination and admitted to Hacettepe University Department of Social Pediatrics and Gülveren Health Center, Ankara. A total of 520 healthy infants were randomized in a 2:2:1 ratio to receive at either Chiron Hib/AlPO4 vaccine or VaxemHib (aluminum hydroxide adjuvant) vaccine or HibTiter (no adjuvant). Vaccines were administered simultaneously with routine diphtheria, tetanus and pertussis (DTaP) and oral polio vaccine (OPV) vaccines at 2, 4 and 6 months of age. Blood samples for anti-plain polysaccharide (PRP) antibody measurement were collected before the first vaccination and 1 month after the last vaccination. After each vaccination parents filled out a diary for 7 days. RESULTS: Out of 520 subjects enrolled, 514 received three doses and were included for safety analysis. Local and systemic reactions occurred with low and similar frequencies in all groups. Only erythema was more common in Chiron Hib/AlPO4 vaccine (19, 10, 11% in Chiron Hib/AlPO4, VaxemHib and HibTiter, respectively, P < 0.05). Nine serious adverse events were reported in seven cases of which none were related to vaccines. A total of 504 subjects were included in the immunogenicity analysis. The three vaccines were highly immunogenic and equivalent in terms of percentage of acquisition of long-term protective levels. The anti-PRP geometric mean titers were 9.9, 8.3 and 5.14 micro g/mL, respectively (P < 0.05). CONCLUSIONS: The use of aluminum compounds adjuvants in Hib-CRM197 conjugate vaccines does not impact the safety profile, while it does increase the magnitude of anti-PRP antibody titers.     

Somatostatin infusion withdrawal in the diagnosis of childhood growth hormone deficiency

OBJECTIVE: An evaluation of growth hormone (GH) testing for GH deficiency (GHD) in childhood is confounded by the lack of a world-wide consensus on the definition of GHD. Although a single GH test remains the most powerful biochemical tool in the evaluation of a child with growth failure, the test remains far from ideal. Withdrawal of somatostatin (SS) infusion is followed by a rebound rise of GH thought to be mediated by endogenous GH-releasing hormone (GHRH) function. This study was designed to compare the GH response to 90 min SS infusion in children with normal GH secretion versus children with GH deficiency. METHODS: Ten children with GHD and 10 healthy controls (NC) have been evaluated for GH response to somatostatin infusion withdrawal (SSIW) and compared with response of two provocative tests, glucagon plus propranolol test and L-Dopa test. All children received constant infusion of somatostatin for 90 min (3 microg/kg per h, Stilamin, Serono, Aubonne, Switzerland). In order to determine GH, blood samples were obtained 90 min before the SS infusion and 0, 15, 30, 45, 60, 75, and 90 min after the cessation of infusion. RESULTS: Growth hormone peak levels with SSIW were significantly lower in GH deficient children than in healthy children (2.5 +/- 1.2 ng/dL, vs 21.9 +/- 5.3 ng/dL, respectively, P < 0.01). No adverse effects were observed during or after somatostatin infusion. CONCLUSION: In the present study, SSIW elicited a significant GH rise in healthy children but not in children with GH deficiency. Although further controlled studies using more data are necessary to expand these findings, the results suggested that children with GH deficiency can be reliably discriminated from healthy children by SSIW.
