Abstract
Cellular composition and the responsiveness of the immune system evolve upon aging and are influenced by biological sex. CD4+ T cells from women living with HIV exhibit a decreased viral replication ex vivo compared to men's. We, thus, hypothesized that these findings could be recapitulated in vitro and infected primary CD4+ T cells with HIV-based vectors pseudotyped with VSV-G or HIV envelopes. We used cells isolated from twenty donors to interrogate the effect of sex and age on permissiveness over a six-day activation kinetics. Our data identified an increased permissiveness to HIV between 24 and 72 h post-stimulation. Sex- and age-based analyses at these time points showed an increased susceptibility to HIV of the cells isolated from males and from donors over 50 years of age, respectively. A parallel assessment of surface markers' expression revealed higher frequencies of activation marker CD69 and of immune checkpoint inhibitors (PD-1 and CTLA-4) in the cells from highly permissive donors. Furthermore, positive correlations were identified between the expression kinetics of CD69, PD-1 and CTLA-4 and HIV expression kinetics. The cell population heterogeneity was assessed using a single-cell RNA-Seq analysis and no cell subtype enrichment was identified according to sex. Finally, transcriptomic analyses further highlighted the role of activation in those differences with enriched activation and cell cycle gene sets in male and older female cells. Altogether, this study brought further evidence about the individual features affecting HIV replication at the cellular level and should be considered in latency reactivation studies for an HIV cure.

Abstract
Als Meralgia paraesthetica (MP) bezeichnet man eine zu den neurologischen Engpasssyndromen zählende Schädigung des aus dem Plexus lumbalis entspringenden sensiblen N. cutaneus femoris lateralis. Symptome sind temporäre oder bleibende Parästhesien und Schmerzen an der Vorder- und Außenseite des Oberschenkels. Die MP kann idiopathisch auftreten, sich genuin als z. B. „seat belt syndrome“ oder „Jeans-Syndrom“ verwirklichen, sie kann aber auch Folge eines operativen Eingriffs oder einer chirurgischen bzw. intensivmedizinischen Lagerung sein. Im Fokus stehen hierbei in der Literatur die Steinschnitt-, die Bauch- und die „Beach-chair“-Lagerung. Analysiert wurden 21 Beschwerden über eine postoperativ erstmals aufgetretene MP, die bei der Gutachterkommission für ärztliche Behandlungsfehler bei der Ärztekammer Nordrhein im Verlauf der letzten 10 Jahre eingereicht wurden. Unter diesen konnten 6 Fälle als Lagerungsschaden nach Steinschnittlagerung identifiziert werden; in 3 Fällen trat eine MP nach Rückenlagerung auf; die Ätiologie konnte nicht sicher geklärt werden. In 12 Fällen wurde die MP als direkte Operationskomplikation erkannt. Pathophysiologie, Inzidenz und Verlauf sowie juristische Implikationen der lagerungsbedingten MP werden beschrieben. Als hauptsächlicher Pathomechanismus wird eine Druckschädigung des Nervs an seiner Kreuzungsstelle mit dem Leistenband diskutiert. Wenngleich alle hier vorgestellten Fälle nach der Steinschnittlagerung auftraten, scheint sich die Komplikation nach Literaturdaten auch bei anderen Lagerungsarten, am häufigsten möglicherweise bei Bauchlagerungen, zu verwirklichen. Dies erklärt auch die zunehmenden Fallberichte einer MP nach Bauchlagerung bei COVID-19-Patient*innen. Eine sichere Vermeidung der lagerungsbedingten Komplikation erscheint aufgrund der anatomischen Variabilität des Nervenverlaufs und der unklaren Pathomechanismen nicht möglich.

Abstract
Two randomized controlled trials (RCTs) in Brazil and Peru demonstrated the effectiveness of CONEMO, a digital intervention supported by trained nurses or nurse assistants (NAs), to reduce depressive symptoms in people with diabetes and/or hypertension. This paper extends the RCTs findings by reflecting on the conditions needed for its wider implementation in routine care services. A qualitative study using semi-structured interviews and content analysis was conducted with nurses/NAs, clinicians, healthcare administrators, and policymakers. Informants reported that CONEMO would be feasible to implement in their health services, but some conditions could be improved before its scale-up: reducing workloads of healthcare workers; raising mental health awareness among clinicians and administrators; being able to inform, deliver and accompany the intervention; assuring appropriate training and supervision of nurses/NAs; and supporting the use of technology in public health services and by patients, especially older ones. We discuss some suggestions on how to overcome these challenges.

Abstract
Introduction Treatment resistant depression (TRD) and severe depression (SD) are common among patients with depression. Patients with inflammatory joint disease (IJD) are at higher risk for developing depression compared to the general population; however, the risk for SD or TRD is not known. Objectives
To examine the odds of patients with IJD for developing SD and TRD compared to non-severe and non-TRD depression. Methods This case-control study was nested within a cohort of patients with incident depression (n=443,384) identified in nationwide Swedish registers 2006-2018. Patients with SD (n=42,975) were identified through the ICD-10 code specifier, through psychiatric hospitalization and/or through suicide attempts. Patients who started a third consecutive treatment for depression were identified with TRD (n=33,830). Each patient was matched with five non-SD - or non-TRD - patients by sociodemographics and year of cohort entry. Crude and adjusted odds ratios (aOR) were calculated by conditional logistic regression with regard to a history of any IJD and specific IJDs prior to depression onset. Results Among patients with depression, those with a history of IJD did not have higher odds for developing SD (aOR 1.09 (95%CI 1.00-1.20)) or TRD (aOR 1.03 (0.93 - 1.14)) compared to patients without IJD. A history of rheumatoid arthritis was associated with a significantly higher odds for SD among patients aged 18-29 (aOR 1.55 (1.01-2.36)) and for TRD among patients aged 30-49 (aOR 1.33 (1.05-1.67). Conclusions Overall, no association was observed between history of IJD and developing SD/TRD; with the exception of younger age strata in rheumatoid arthritis.

Abstract
Because of a painful right-sided coxarthrosis a 57-year-old female patient underwent a cementless total arthroplasty under general anesthesia. Except for Asperger's syndrome and an occlusion of a vein in her left eye she stated no other diseases or complaints, especially no cardiac problems. Postoperatively she developed neurological symptoms of left-sided hemiparesis and hemihypesthesia. A cranial computer tomography was performed and a right-sided infarction of the thalamic region was found. A patent foramen ovale (PFO) and atrial septal aneurysm were detected 5 days later. The incidence of a PFO is given as 25% of the population. A paradoxical air embolism in the presence of a PFO is a feared complication in neurosurgical interventions in a semi-sitting or sitting position. Corpuscular emboli, such as bone, cement, fat or wound debris may be the reason for paradoxical embolisms in combination especially with partial or total hip replacement. The kind of embolism in the case described could not be clarified. Deep vein thrombosis or cardiac arrhythmia could be excluded. Therefore, it can be considered most likely that the operation site was the source of the embolism. The trigger for a paradoxical embolism is a reversal of the pressure difference between the right and left atria: normally the left atrial pressure exceeds the right atrial pressure by ca. 2-4 mm Hg, resulting possibly in a small clinically irrelevant left-to-right shunt. If the pulmonary arterial circulation is compromised and pulmonary vascular resistance increases, the pressure gradient between the left and right atria reverses and a right-to-left shunt can occur causing a paradoxical embolism. Positive end-expiratory pressure (PEEP) ventilation during anesthesia could be an important reason for a shunt reversal between the right and left atria and therefore favoring a paradoxical embolism but the pathophysiological role of PEEP has not yet been finally clarified.

Abstract
While analyses of cell populations provide averaged information about viral infections, single-cell analyses offer individual consideration, thereby revealing a broad spectrum of diversity as well as identifying extreme phenotypes that can be exploited to further understand the complex virus-host interplay. Single-cell technologies applied in the context of human immunodeficiency virus (HIV) infection proved to be valuable tools to help uncover specific biomarkers as well as novel candidate players in virus-host interactions. This review aims at providing an updated overview of single-cell analyses in the field of HIV and acquired knowledge on HIV infection, latency, and host response. Although HIV is a pioneering example, similar single-cell approaches have proven to be valuable for elucidating the behavior and virus-host interplay in a range of other viruses.

Abstract
Background:The therapeutic aim for rheumatoid arthritis (RA) is to control disease activity and prevent radiographic progression. Various clinical scores are utilized to describe disease activity in RA patients. The DAS28 score can define states of low disease activity (LDA) and remission. Despite achieving LDA or remission, radiographic progression may nevertheless occur. However, the rates and frequency of this occurrence have not been analyzed in detail.Objectives:To describe the frequency and rate of radiographic progression in patients with persistent LDA or remission.Methods:Analysis of RA patients from the SCQM cohort. Persistent LDA or remission were defined as DAS 28 ≤3.2 or <2.6 respectively, at two subsequent follow up time points in the database. We included patients with at least two sets of radiographs within these intervals of LDA and/or remission. Radiographic progression was measured with the Ratingen-score (range 0-190), which describes joint erosions numerically. Repair was defined as an improvement in the Ratingen score >5 points/year and progression as >2 or >5 points change in the Ratingen score within one year.Results:Among 10’141 RA patients, 4’342 episodes of remission occurred in 3’927 patients with 1’776 sets of X rays available within these episodes. Similarly, 8’136 episodes of LDA in 6’765 patients and 2’358 sets of X rays were present within these intervals. For patients in LDA or remission, rates of repair were 5.5% and 4.8%, respectively, while for radiographic progression >5 points in the Ratingen score/year were 10.3% in both groups and for >2 points change of Ratingen score/year were 27.7 and 25.4%, respectively).No differences for demographic factors or measures of disease activity, rheumatoid factor or ACPA were found comparing patients with radiographic progression or non-progression despite LDA or remission at the beginning of the episode of LDA and/or remission.Interestingly, 42.9% of patients in LDA with progression of >5 points in the Ratingen score/year were current smokers vs 29.4% among the non-progressors (X2 = 6.55, p = 0.01). This significant difference vanished when the cut-off for radiographic progression was set at >2 points yearly change in Ratingen score or in patients in remission.Conclusion:Radiographic progression despite LDA or remission are more frequent than expected. No differences in radiographic progression were found comparing LDA and remission suggesting that the goal of LDA is appropriate. Smoking seems to be an independent risk factor for radiographic progression despite LDA. Why the effect of smoking could was not demonstrated in patients in remission, remains unclear.Disclosure of Interests:Lena Brandt: None declared, Hendrik Schulze-Koops: None declared, Thomas Hügle Consultant of: GSK, Abbvie, Pfizer, Jansen, Novartis, Eli Lilly., Michael J.

Abstract
A 61-year-old woman underwent a tension-free vaginal tape (TVT) operation due to stress incontinence. After technically difficult spinal anesthesia with two attempts the patient developed symptoms of nerve irritation, complained about neckache and headache and showed signs of agitation. The regimen was shifted to general anesthesia and surgery was performed. Because of postoperatively persistent headache and sensory disturbances an MRI scan of the lumbar spine was performed on the first postoperative day without pathological findings. The patient was able to leave the hospital after 1 week with significant relief of symptoms but 3 weeks later she developed neurocognitive impairment with memory deficits. A second MRI scan of the head now showed signs of disturbance of CSF circulation with hydrocephalus. Treatment was performed with drainage and ventriculoperitoneal shunt. Further evaluation showed a severe, multisegmental arachnoiditis and the patient developed a progressive paraparesis. The patient presented her case for assessment to a commission on medical malpractice 13 months after anesthesia. The commission detected no treatment errors. In connection to the case report a literature review of characteristics and etiologies of chronic adhesive arachnoiditis is given, which is a known but very rare complication of spinal anesthesia or similar procedures.

Abstract
In 1588 Sebastian Weiß, the son of a miller, became the first Lutheran pastor of Dittersbach in Saxony. At home he had repeatedly witnessed successful resuscitation of drowned persons by means of simple measures by his parents. Missing appropriate recommendations in the medical literature, in 1620 as "Sebastianus Albinus" he published a booklet with measures for reviving apparently drowned persons. This Kurtze Bericht und Handgrieff (Brief report and handgrip) attracted great attention amongst physicians, especially the reprint of 1675 of which a few copies still exist. The first printed edition from 1620 was lost until, some years ago, the apparently only still existing copy was rediscovered in the Herzog August Library in Wolfenbüttel.

Abstract
Candida albicans is an important human pathogen and a major concern in intensive care units around the world. C. albicans infections are associated with a high mortality despite the use of antifungal treatments. One of the causes of therapeutic failures is the acquisition of antifungal resistance by mutations in the C. albicans genome. Fluconazole (FLC) is one of the most widely used antifungal and mechanisms of FLC resistance occurring by mutations have been extensively investigated. However, some clinical isolates are known to be able to survive at high FLC concentrations without acquiring resistance mutations, a phenotype known as tolerance. Mechanisms behind FLC tolerance are not well studied, mainly due to the lack of a proper way to identify and quantify tolerance in clinical isolates. We proposed here culture conditions to investigate FLC tolerance as well as an easy and efficient method to identity and quantify tolerance to FLC. The screening of C. albicans strain collections revealed that FLC tolerance is pH- and strain-dependent, suggesting the involvement of multiple mechanisms. Here, we addressed the identification of FLC tolerance mediators in C. albicans by an overexpression strategy focusing on 572 C. albicans genes. This strategy led to the identification of two transcription factors, CRZ1 and GZF3. CRZ1 is a C2H2-type transcription factor that is part of the calcineurin-dependent pathway in C. albicans, while GZF3 is a GATA-type transcription factor of unknown function in C. albicans. Overexpression of each gene resulted in an increase of FLC tolerance, however, only the deletion of CRZ1 in clinical FLC-tolerant strains consistently decreased their FLC tolerance. Transcription profiling of clinical isolates with variable levels of FLC tolerance confirmed a calcineurin-dependent signature in these isolates when exposed to FLC.

Abstract
BACKGROUND Impairments of social cognition are considered core features of schizophrenia and are established predictors of social functioning. However, affective aspects of social cognition including empathy have far less been studied than its cognitive dimensions. The role of empathy in the development of schizophrenia remains largely elusive. METHODS Emotional and cognitive empathy were investigated in large sample of 120 individuals at Clinical High Risk of Psychosis (CHR-P) and compared with 50 patients with schizophrenia and 50 healthy controls. A behavioral empathy assessment, the Multifaceted Empathy Test, was implemented, and associations of empathy with cognition, social functioning, and symptoms were determined. RESULTS Our findings demonstrated significant reductions of emotional empathy in individuals at CHR-P, while cognitive empathy appeared intact. Only individuals with schizophrenia showed significantly reduced scores of cognitive empathy compared to healthy controls and individuals at CHR-P. Individuals at CHR-P were characterized by significantly lower scores of emotional empathy and unspecific arousal for both positive and negative affective valences compared to matched healthy controls and patients with schizophrenia. Results also indicated a correlation of lower scores of emotional empathy and arousal with higher scores of prodromal symptoms. CONCLUSION Findings suggest that the tendency to 'feel with' an interaction partner is reduced in individuals at CHR-P. Altered emotional reactivity may represent an additional, early vulnerability marker, even if cognitive mentalizing is grossly unimpaired in the prodromal stage. Different mechanisms might contribute to reductions of cognitive and emotional empathy in different stages of non-affective psychotic disorders and should be further explored.

Abstract
Rayleigh-Taylor (RT) fluid turbulence through a bed of rigid, finite-size spheres is investigated by means of high-resolution direct numerical simulations, fully coupling the fluid and the solid phase via a state-of-the-art immersed boundary method. The porous character of the medium reveals a totally different physics for the mixing process when compared to the well-known phenomenology of classical RT mixing. For sufficiently small porosity, the growth rate of the mixing layer is linear in time (instead of quadratical) and the velocity fluctuations tend to saturate to a constant value (instead of linearly growing). We propose an effective continuum model to fully explain these results where porosity originated by the finite-size spheres is parametrized by a friction coefficient.

Abstract
OBJECTIVE There is some evidence that clozapine is significantly underutilised. Also, clozapine use is thought to vary by country, but so far no international study has assessed trends in clozapine prescribing. Therefore, this study aimed to assess clozapine use trends on an international scale, using standardised criteria for data analysis. METHOD A repeated cross-sectional design was applied to data extracts (2005-2014) from 17 countries worldwide. RESULTS In 2014, overall clozapine use prevalence was greatest in Finland (189.2/100 000 persons) and in New Zealand (116.3/100 000), and lowest in the Japanese cohort (0.6/100 000), and in the privately insured US cohort (14.0/100 000). From 2005 to 2014, clozapine use increased in almost all studied countries (relative increase: 7.8-197.2%). In most countries, clozapine use was highest in 40-59-year-olds (range: 0.6/100 000 (Japan) to 344.8/100 000 (Finland)). In youths (10-19 years), clozapine use was highest in Finland (24.7/100 000) and in the publicly insured US cohort (15.5/100 000). CONCLUSION While clozapine use has increased in most studied countries over recent years, clozapine is still underutilised in many countries, with clozapine utilisation patterns differing significantly between countries. Future research should address the implementation of interventions designed to facilitate increased clozapine utilisation.

Abstract
Intracranial dermoid cysts occasionally rupture spontaneously into the ventricles or into the subarachnoid space. In such cases, intraventricular fat-fluid levels are invariably evident at computed tomography and may even be visible on a conventional radiograph of the skull. A case is described in which fat was observed to remain in the ventricles long after surgical removal of a dermoid cyst. We think that this fat, by causing obstruction of the cerebrospinal fluid pathways, should be regarded as a potential cause of intermittent elevation of intracranial pressure.

Abstract
Twenty-six patients with cervical radiculopathy and/or myelopathy caused by spondylosis or disk herniation were examined with myelography, CT myelography and MR. Fourteen of the patients were operated upon and 11 of them underwent postoperative MR and CT. The three radiologic methods provided comparable information about narrowing of the subarachnoid space and compression of the spinal cord. It was more difficult to distinguish bone from soft tissue with MR only, but the combination of MR and conventional radiography gave sufficient information for this differentiation. When radiologic nerve root sheath deformity was compared with clinical radiculopathy, myelography, CT myelography and MR had similar sensitivity and accuracy. Postoperative MR could reveal remaining indentation on the thecal sac and the cord but CT without contrast medium was useful as a complement to determine the aetiology of the indentation. Because MR has several practical advantages, it is well suited as the primary imaging modality, together with conventional radiography, for the preoperative radiologic evaluation of patients with cervical radiculopathy and/or myelopathy. Postoperative MR is useful in patients with persistent or new symptoms.

Abstract
Objectives: In adults, impaired fasting glycemia (IFG) increases the risk for type 2 diabetes mellitus (T2DM). This study aimed to investigate to which extent children with obesity develop T2DM during early adulthood, and to determine whether IFG and elevated hemoglobin A1c (HbA1c) in obese children are risk markers for early development of T2DM. Methods: In this prospective cohort study, 1620 subjects from the Swedish Childhood Obesity Treatment Registry – BORIS who were ⩾18 years at follow-up and 8046 individuals in a population-based comparison group, matched on gender age and living area, were included. IFG was defined according to both ADA (cut-off 5.6 mmol l−1) and WHO (6.1 mmol l−1). Elevated HbA1c was defined according to ADA (cut-off 39 mmol l−1). Main outcome was T2DM medication, as a proxy for T2DM. Data on medications were retrieved from a national registry. Results: The childhood obesity cohort were 24 times more likely to receive T2DM medications in early adulthood compared with the comparison group (95% confidence interval (CI): 12.52–46). WHO-defined IFG predicted future use of T2DM medication with an adjusted hazard ratio (HR) of 3.73 (95% CI: 1.87–7.45) compared with those who had fasting glucose levels <5.6 mmol l−1. A fasting glucose level of 5.6–6.0 mmol l−1, that is, the IFG-interval added by American Diabetes Association (ADA), did not increase the use of T2DM medication more than pediatric obesity itself, adjusted HR=1.72 (0.84–3.52). Elevated levels of HbA1c resulted in an adjusted HR=3.12 (1.50–6.52). More severe degree of obesity also increased the future T2DM risk. CONCLUSION: IFG according to WHO and elevated HbA1c (39–48 mmol l−1), but not the additional fasting glucose interval added by ADA (5.6–6.0 mmol l−1), can be considered as prediabetes in the obese pediatric population in Sweden.

Abstract
A unifying feature in the pathogenesis of aging, neurodegenerative disease, and lysosomal storage disorders is the progressive deposition of macromolecular debris impervious to enzyme catalysis by cellular waste disposal mechanisms (e.g., lipofuscin). Aerobic exercise training (AET) has pleiotropic effects and stimulates mitochondrial biogenesis, antioxidant defense systems, and autophagic flux in multiple organs and tissues. Our aim was to explore the therapeutic potential of AET as an ancillary therapy to mitigate autophagic buildup and oxidative damage and rejuvenate the mitochondrial-lysosomal axis in Pompe disease (GSD II/PD). Fourteen weeks of combined recombinant acid α-glucosidase (rhGAA) and AET polytherapy attenuated mitochondrial swelling, fortified antioxidant defense systems, reduced oxidative damage, and augmented glycogen clearance and removal of autophagic debris/lipofuscin in fast-twitch skeletal muscle of GAA-KO mice. Ancillary AET potently augmented the pool of PI4KA transcripts and exerted a mild restorative effect on Syt VII and VAMP-5/myobrevin, collectively suggesting improved endosomal transport and Ca(2+)- mediated lysosomal exocytosis. Compared with traditional rhGAA monotherapy, AET and rhGAA polytherapy effectively mitigated buildup of protein carbonyls, autophagic debris/lipofuscin, and P62/SQSTM1, while enhancing MnSOD expression, nuclear translocation of Nrf-2, muscle mass, and motor function in GAA-KO mice. Combined AET and rhGAA therapy reactivates cellular clearance pathways, mitigates mitochondrial senescence, and strengthens antioxidant defense systems in GSD II/PD. Aerobic exercise training (or pharmacologic targeting of contractile-activity-induced pathways) may have therapeutic potential for mitochondrial-lysosomal axis rejuvenation in lysosomal storage disorders and related conditions (e.g., aging and neurodegenerative disease).

Abstract
A partial anomalous pulmonary venous connection (PAPVC) is a congenital abnormality of the great thoracic vessels the incidence of which is underestimated and is associated with a left-right shunt. It rarely develops into a right-sided cardiac insufficiency. Because of the mostly low left-right shunt volume, a PAPVC is often asymptomatic and mostly incidentally detected in advanced age. Incorrect positioning of a central venous catheter or paradoxical blood gas parameters can serve to indicate the presence of a PAPVC. This article presents the case a 50-year-old patient with a PAPVC of the left upper lobe pulmonary vein draining into the left innominate vein without prior clinical symptoms. Blood gas analyses from the superior vena cava, where the catheter placement was confirmed by computed tomography angiography, showed unexplainable arterial values. The anatomical abnormality was confirmed by computed tomography.

Abstract
Nerve injuries are a rare complication of airway management. Two cases of Tapia's syndrome following orotracheal intubation are reported. Case 1: a 23-year-old male patient underwent an otorhinolaryngology (ENT) surgical procedure with orotracheal intubation. A left-sided Tapia's syndrome was verified 3 days later. Case 2: a 67-year-old patient developed a right-sided Tapia's syndrome following an arthroscopic intervention of the left shoulder in the beach-chair position. In both cases there was permanent damage of both nerves. On the basis of a comprehensive literature survey the reasons for an intubation-induced Tapia's syndrome are discussed. In order to avoid a glottis or immediate subglottic position it is recommended to check and to document the position of the cuff (depth of intubation) and the measured cuff pressure immediately after intubation. It also seems to be advisable to document an overstretched head position if required for the operation.

Abstract
AIM To assess prescribing patterns, sociodemographic characteristics and previous disease history in patients receiving pregabalin. METHODS An observational study using register data on dispensed drugs and recorded diagnoses for all patients in Stockholm, Sweden, who filled at least one prescription of pregabalin between July 2005 and December 2009. Analyses focused on prevalence, incidence, diagnosis patterns, prior dispensing of other analgesics/psychotropics and persistence to treatment over time. RESULT A total of 18,626 patients (mean age 55 years, 63% women) were initiated on treatment between July 2006 and December 2009. Approved indications were recorded in hospital and/or primary care within 1 year prior to the first dispensing for 40% of the patients (epilepsy 1.3%, neuropathic pain 35.5% and generalised anxiety disorder (GAD) 3.6%). Antidepressants were used by 55%, opioids by 49% and sedatives by 48% prior to initiation of pregabalin. One-third (34%) only purchased one prescription and the proportion purchasing pregabalin 1 year after initiation was 42.1% for epilepsy, 36.3% for GAD, 21.5% for neuropathic pain and 25.6% for those without any of the included diagnoses. CONCLUSION Pregabalin was mainly used as a second-line drug for the treatment of GAD or neuropathic pain and to a lesser extent as add-on therapy in epilepsy. However, a large proportion of all patients only purchased one prescription and the persistence declined rapidly over time. The issue of potential off-label prescribing or poor registration of diagnoses should also be noted as a high proportion had been prescribed the drug without a record of any of the approved indications.

Abstract
IntroductionSuicide risk is increased in patients with a history of psychiatric hospitalization.AimTo explore how suicide risk varies by age during psychiatric hospitalization and in the year post-discharge.MethodsThis is a population-based case-control study of all suicides (n = 20,675; 70% male) in Sweden aged ≥18 years during 1991–2003. Each suicide was individually matched to 10 population controls by age, sex, and county of residence. Discharge diagnoses of a mental disorder (except dementia and other organic disorders) in the year prior to suicide were identified by register linkage. Odds ratios (OR) were calculated by conditional logistic regression to estimate the relative risk of suicide in those with psychiatric diagnoses compared to the general population. ORs were estimated by age group (18–34 years, 35–49 years, 50–64 years, and ≥ 65 years) and timing of the suicide in relation to discharge.ResultsDuring hospitalization, the youngest age group had the greatest suicide risk elevation [OR 64 (95% CI 44-92)]. In the first month post-discharge, the oldest age group had the highest suicide risk elevation [OR 162 (95% 66–399) in the first week and OR 127 (95% 67–242) in the second to fourth weeks]. In the remaining eleven months, suicide risk elevation was lower and relatively similar in different age groups.ConclusionsDuring the year following psychiatric hospitalization, an especially high attention should be paid to the suicide risk of the elderly patients in the first month post-discharge.

Abstract
In a patient with advanced Hodgkin's disease (HD) associated with generalized pruritus, an unexpected relief of itching was found to be an early sign of spinal cord compression. Following irradiation of an extradural mass at the Th II level, itching recurred. Although the mechanisms bringing about itching in HD are unknown, the relief and recurrence of the symptom in our patient are in line with a peripheral origin of pruritus in the disease. Spontaneous relief of pruritus in HD despite other signs of active disease should prompt a neurological examination, since early recognition and treatment of spinal cord compression in lymphoma are important to avoid residual neurological disability.
