Abstract
Behavioural flexibility is key to survival in a dynamic environmentWhile flexible, goal-directed behaviours are initially dependent on dorsomedial striatum, they become dependent on lateral striatum as behaviours become inflexible. Similarly, lesions of dopamine terminals in lateral striatum disrupt the development of inflexible habits. This work suggests that dopamine release in lateral striatum may drive inflexible behaviours, though few studies have investigated a causative role of subpopulations of striatal dopamine terminals in reversal learning, a measure of flexibility. Here, we performed two optogenetic experiments to activate dopamine terminals in dorsomedial (DMS), dorsolateral (DLS) or ventral (nucleus accumbens [NAc]) striatum in DAT-Cre mice that expressed channelrhodopsin-2 via viral injection (Experiment I) or through transgenic breeding with an Ai32 reporter line (Experiment II) to determine how specific dopamine subpopulations impact reversal learning. Mice performed a reversal task in which they self-stimulated DMS, DLS, or NAc dopamine terminals by pressing one of two levers before action-outcome lever contingencies were reversed. Largely consistent with presumed ventromedial/lateral striatal function, we found that mice self-stimulating medial dopamine terminals reversed lever preference following contingency reversal, while mice self-stimulating NAc showed parial flexibility, and DLS self-stimulation resulted in impaired reversal. Impairments in DLS mice were characterized by more regressive errors and reliance on lose-stay strategies following reversal, as well as reduced within-session learning, suggesting reward insensitivity and overreliance on previously learned actions. This study supports a model of striatal function in which DMS and ventral dopamine facilitate goal-directed responding, and DLS dopamine supports more inflexible responding.

Abstract
In recent years, indications for implanting mega-implants were established in managing major bone defects linked to revision arthroplasty due to loosening, periprosthetic fractures, re-implantation following periprosthetic joint infection, non-union following fractures as well as complex intraarticular primary fractures. This study was conducted to discuss and analyze the strategy of diagnosis and management of complications following the use of mega-implants in treating primary and periprosthetic fractures of the lower extremities. This is a monocentric retrospective study. Patients aged ≥ 18 years who underwent implantation of a megaendoprosthesis due to periprosthetic or primary fractures of the lower extremity between January 2010 and February 2023 were identified from the authors' hospital information system. We identified 96 patients with equal numbers of fractures (71 periprosthetic fractures and 25 primary fractures). 90 cases out of 96 were investigated in this study. The drop-out rate was 6.25% (six cases). The average follow-up period was 22 months (1 to 8 years) with a minimum follow-up of 1 year. The diagnosis of complications was provided on the basis of subjective symptoms, clinical signs, radiological findings and laboratory investigations such as C-reactive protein, leucocyte count and the microbiological findings. The indications for implantations of modular mega-implants of the lower extremities were periprosthetic fractures (65 cases/72.22%) and primary fractures (25 cases/27.78%). Pathological fractures due to malignancy were encountered in 23 cases (25.56%), in one case due to primary tumor (1.11%) and 22 cases due to metastatic lesions (24.44%). Two cases (2.22%) presented with primary intraarticular fractures with severe osteoporosis and primary arthrosis. In all cases with malignancy staging was performed. Regarding localization, proximal femur replacement was encountered in 60 cases (66.67%), followed by distal femur replacement (28 cases/31.11%) and total femur replacement (2 cases/2.22%). The overall complication rate was 23.33% (21 complications in 21 patients). The most common complication was dislocation which was encountered in nine cases (10%), all following proximal femoral replacement (9 cases out of 60, making 15% of cases with proximal femoral replacement). The second most common complication was infection (six cases, 6.67%), followed by four aseptic loosenings (4.44%), further intraoperative periprosthetic fracture in one case (1.11%) and a broken implant in one case (1.11%). We noticed no cases with wear and tear of the polyethylene components and no cases of disconnections of the modular components. Mega-endoprostheses enable versatile management options in the treatment of primary and periprosthetic fractures of the lower extremities. The rate of complications such as loosening, implant failure, dislocation and infection are within an acceptable range in this preliminary analysis. However, implantation of mega-endoprostheses must be strictly indicated due the limited salvage options following surgery.

Abstract
As key actors in embryogenesis and organogenesis, fibroblast growth factors (FGFs) can assume a protective or an aggravative role in pulmonary fibrosis pathophysiology. Among the FGFs, endocrine FGFs (FGF19, FGF21 and FGF23), are characterized by low affinity to FGF receptors (FGFRs), enabling them to deploy endocrine activity in several organs. More specifically, their anti-fibrotic role has been reported in liver, kidney or myocardial fibrosis. Endocrine FGFs are of growing interest on account of their potential anti-fibrotic role in pulmonary fibrogenesis, as well. In this review, we aim to summarize current knowledge on the protective effects of endocrine FGFs in pulmonary fibrosis.

Abstract
A sense of agency (SoA) over wilful actions is thought to be dependent on the level of choice and the nature of the outcome. In a preregistered study, we manipulated choice and valence of outcome to assess the relationship between SoA across the depression and psychosis continuum. Participants (N = 151) completed a Libet Clock task, in which they had either a free or forced choice to press one of two buttons and received either a rewarding or punishing outcome. Participants also completed questionnaires on depressive and psychosis-like traits. Rewarding outcomes increased intentional binding. The evidence favoured no effect of choice on average, but this was influenced by inter-individual differences. Individuals reporting more depressive traits had less of a difference in intentional binding between free and forced choice conditions. We show that implicit SoA is sensitive to outcome valence and the effect of choice differs across the depression continuum.

Abstract
Introduction The diagnosis and management of periprosthetic knee and hip infections as well as the identification and management of possible additional infectious foci is of great importance for successful therapy. This study analyses the importance of 18F deoxyglucose PET-CT (PET-CT) in the identification of additional infectious focus and subsequent impact on management of periprosthetic infection (PPI). Material and methods A retrospective analysis of the clinical data and findings in the period from January 2008 to December 2018 was carried out. One hundred and four patients with in-hospital treatment due to PPI of a hip or knee joint were identified and included in this study. All patients underwent a standardized clinical examination and further surgical and antibiotic therapy. The reevaluation of performed PET-CTs was specifically carried out with regard to the local PPI or detection of secondary foci. Results PET-CT successfully verified the PPI in 84.2% of the patients. A total of 78 possible additional foci were detected in PET-CT in 56 (53.8%) of the examined patients. Predilection sites for possible secondary foci were joints (42.3%), pulmonary (15.4%), ear-nose-throat (15.4%), spine (11.5%), and the musculocutaneous tissues (11.5%). Fifty-four positive PET-CT findings were confirmed clinically with need of additional adequate treatment. Conclusion PET-CT is a valuable diagnostic tool to confirm periprosthetic joint infection. At the same time, the whole-body PET/CT may detect additional foci of infection with impact on subsequent treatment strategy. PET was of special value in detecting infections at distant locations far from the primary infected joint in significant number. These distant infection locations can be potential cause of a re-infection. This clearly reflects the need of their diagnosis.

Abstract
Habits are inflexible behaviors that develop after extensive repetition, and overreliance on habits is a hallmark of many pathological states. The striatum is involved in the transition from flexible to inflexible responding, and interspersed throughout the striatum are patches, or striosomes, which make up ~15% of the volume of the striatum relative to the surrounding matrix compartment. Previous studies have suggested that patches are necessary for normal habit formation, but it remains unknown exactly how patches contribute to habit formation and expression. Here, using optogenetics, we stimulated striatal patches in Sepw1-NP67 mice during variable interval training (VI60), which is used to establish habitual responding. We found that activation of patches at reward retrieval resulted in elevated responding during VI60 training by modifying the pattern of head entry and pressing. Further, this optogenetic manipulation reduced subsequent responding following reinforcer devaluation, suggesting modified habit formation. However, patch stimulation did not generally increase extinction rates during a subsequent extinction probe, but did result in a small 'extinction burst', further suggesting goal-directed behavior. On the other hand, this manipulation had no effect in omission trials, where mice had to withhold responses to obtain rewards. Finally, we utilized fast-scan cyclic voltammetry to investigate how patch activation modifies evoked striatal dopamine release and found that optogenetic activation of patch projections to the substantia nigra pars compacta (SNc) is sufficient to suppress dopamine release in the dorsal striatum. Overall, this work provides novel insight into the role of the patch compartment in habit formation, and provides a potential mechanism for how patches modify habitual behavior by exerting control over dopamine signaling.

Abstract
INTRODUCTION Asthma is a common disease whose diagnosis does not typically rely on the results of imaging. However, chest CT has gained a key place over the last decade to support the management of patients with difficult to treat and severe asthma. STATE OF THE ART Bronchial wall thickening and mild dilatation or narrowing of bronchial lumen are frequently observed on chest CT in people with asthma. Bronchial wall thickening is correlated to the degree of obstruction and to bronchial wall remodeling and inflammation. Diverse conditions which can mimic asthma should be recognized on CT, including endobronchial tumours, interstitial pneumonias, bronchiectasis and bronchiolitis. Ground-glass opacities and consolidation may be related to transient eosinophilic infiltrates, infection or an associated disease (vasculitis, chronic eosinophilic pneumonia). Hyperdense mucous plugging is highly specific for allergic bronchopulmonary aspergillosis. PERSPECTIVES Airway morphometry, air trapping and quantitative analysis of ventilatory defects, with CT or MRI, can help to identify different morphological subgroups of patients with different functional or inflammatory characteristics. These imaging tools could emerge as new biomarkers for the evaluation of treatment response. CONCLUSION Chest CT is indicated in people with severe asthma to search for additional or alternative diagnoses. Quantitative imaging may contribute to phenotyping this patient group.

Abstract
INTRODUCTION The epidemiology of chronic beryllium disease (CBD) in France is poorly understood. The aim of this study was to determine the number of prevalent cases of CBD in France between 2010 and 2014. METHODS We conducted a national survey using a specific questionnaire distributed by the professional pathology services. RESULTS In total, 33 CBD cases were reported in France, with a diagnosis established between 1982 and 2014. 85% (28/33) of CBD cases resulted from professional exposure and mostly concerned foundry workers (39%). A definite diagnosis defined by the association of an abnormal beryllium lymphocyte proliferation test and of a granulomatous inflammatory response in the lung, was obtained in 29/33 cases (88%). The other cases were probable CBD, defined by a granulomatous lung disease with a beryllium exposure, but without evidence of beryllium sensitisation. The diagnosis of granulomatous disease was confirmed a mean of 4 years after the end of exposure. The median delay between diagnosis of a granulomatous disease and diagnosis of CBD was 2 years (range 0-38 years). A genetic predisposition was found in 14 of 17 tested patients (82%). CONCLUSION In this study, we report 33 cases of CBD followed in France between 2010 and 2014. The poor understanding of CBD and the exposure leading to it, the late development after the end of exposure, the complexity of the diagnosis and the similarities with sarcoidosis may explain the small number of cases reported.

Abstract
Appropriate analgesic therapy requires adequate pain measurement. A few studies have already demonstrated benefits of clinical pharmacists supporting physicians' prescribing. Nevertheless, there are still open questions about pharmaceutical interventions at the nursing level in order to optimise pain therapy sustainably. We performed a prospective controlled follow-up intervention study to analyse the sustainability of improved pain measurement performance (PMP) and its therapeutic consequences. Half a year after a successful guidance implementation in two study units (control and intervention unit), pharmacists performed an individual coaching for nurses only in the intervention unit. We consecutively monitored patient-nurse contacts and evaluated PMP with a 7-point scale (from 0: no pain measurement to 6: optimal pain measurement) in three 4-week periods (t1 : before guidance implementation, t₂ : directly after guidance implementation, t₃ : half a year after guidance implementation) on both units. Therapeutic consequences of PMP were evaluated in a post-hoc patient chart review. In the t1 period, we found a median PMP of 0 in both units which rose to 6 (control unit) vs. 5 (intervention unit) in t₂ period due to guidance implementation in both units. In the t₃ period, we found a decrease of PMP to 0 in controls vs. to 4 in the intervention unit (p<0.001). We also found, that improved PMP did not lead to a more individualised analgesic prescribing and administration of more on-demand analgesics. A coaching concept of clinical pharmacists improved the sustainability of nurses' PMP after a successful guidance implementation. Our results illustrate the potential of including clinical pharmacist in interprofessional pain therapy teams.

Abstract
INTRODUCTION Intravascular leiomyoma is a rare type of myoma. It was firstly described by Birch-Hirschfeld in 1896, however, its intracardiac subtype was firstly reported by Durck in 1907. Most patients are asymptomatic. The tumor invades mostly the tributaries of the inferior vena cava (IVC) with upward extension that may approach the intracardiac space. AIM By means of a scientific case report, a patient with the very rare diagnosis of an endocaval leiomyoma thrombus post-hysterectomy is described based on the clinical experiences obtained in the specific case management and selective references from the literature. CASE PRESENTATION A 48-years old female was diagnosed with intravascular tumor growth within the IVC with intracardiac extension using chest and abdominal CT scan, ECG and echocardiography which was approached by an interdisciplinary (vascular and cardiothoracic) surgical intervention (278 min) including heart-lung machine (99 min) with favorable postoperative result (R0 resection status with mid-term outcome, no recurrent tumor growth). Histopathological investigation diagnosed leiomyoma origin already from ovarian vein most likely in context to the former hysterectomy (3 years ago). DISCUSSION AND CONCLUSION Intravascular leiomyoma is a benign tumor with invasive tendency, which can be considered a diagnostic and therapeutic challenge. It should be thoroughly investigated to be planned for a radical surgical removal. By possible adherence to the intraabdominal or -thoracic organs, an interdisciplinary and eventually step-wise surgical approach (combining vascular, abdominal, thoracic and heart surgery as well as gynecology and urology), which can be demanding, is recommended to be seriously considered to i) reliably achieve R0 resection status and, thus, ii) provide best outcome, quality of life and prognosis.

Abstract
BACKGROUND Endoprosthetic care of high hip dislocation is a surgical challenge. The hip anatomy is greatly altered in these patients, including a rather flat and small acetabulum with impaired bone quality and a relevant chance of a bony defect of the acetabular roof. Additionally, the front coverage and in some cases even the dorsal coverage of the hip are missing. The proximal femur is characterized with an increased antetorsion, a coxa valga position and an enlarged greater trochanter. The medullary cavity is narrowed, the offset is reduced, and the absolut leg length can be enlarged. Further anatomic variations can have been caused by previous surgeries. AIM OF THE TREATMENT The goal of the endoprosthetic care is the re-creation of a hip with an anatomic center of rotation, an anatomic offset and equal leg length. TREATMENT This can be achieved by a medial shift of the acetabular cup. An acetabular osteotomy including central cancellous bone graft or a bony graft to reinforce the acetabular roof might be necessary. In cases in which an anatomic acetabular cup placement is not possible, a more cranial placement can be done. Further strategies that are essential in several cases are shortening or re-orientation osteotomies of the femur, reaming of the medullary cavity and correct implant selection. Additionally, thorough soft tissue management is of main importance. Generally, the surgery should be well prepared preoperatively.

Abstract
INTRODUCTION Mycobacterium avium complex can be responsible for a number of different radio-clinical presentations, ranging from invasive infections to hypersensitivity pneumonitis due to repeated inhalation of antigens. The diagnosis of hypersensitivity pneumonitis is clinical, radiological, biological and microbiological. CASE REPORT A 61-year-old male developed a hypersensitivity pneumonitis reaction to non-tuberculous mycobacteria, following the repeated use of his own spa, which later evolved into chronic respiratory failure. The diagnosis was made via an environmental analysis. Immunosuppressive treatment comprising corticosteroids and methotrexate led to moderate improvement, but may also have been responsible for the development of a M. intracellulare abscess. Despite 12 months of well-conducted antibiotic treatment, the evolution was unfavourable, with a relapse of a M. intracellulare infection three months after the end of treatment, followed by the patient's death. CONCLUSION Hypersensitivity pneumonitis reaction to non-tuberculous mycobacteria should be considered in patients who have their own spa. In the absence of microbiological identification, environmental analysis may guide the diagnosis. A fatal evolution of PHS is infrequent but prognosis may depend on the degree of associated fibrosis.

Abstract
Periprosthetic patella fractures occur both with and without retropatellar joint replacement. A non-operative treatment yields satisfactory results with low morbidity. It can be applied in minimally displaced fractures that have an intact retropatellar component and an intact extensor mechanism, combined with an initial immobilization. The surgical treatment is associated with relatively poor results and with high complication rates. There was only minor improvement of functional results, no matter which surgical technique was used. Surgical intervention is still required in fractures with a loosening of the patellar component, considerable dislocations of fragments, and damage to or rupture of the extensor mechanism. In particular, type II fractures require repair of the extensor mechanism and the fracture or patellectomy. Type III fractures require a revision or resection of the patella, a patelloplasty or total patellectomy. In addition, early or late reconstruction using allograft to restore the extensor mechanism can be taken in consideration.

Abstract
IntroductionSuicide in children and adolescents is commonly underreported and studied. It is an interplay area of multiple static (sociodemographic), and modifiable (impulsivity, psychiatric morbidities, adverse life events (ALE), abuse, bullying) variables.Objectives and aimTo assess and identify relative significance of dependent and independent risk factors in youngsters attempting self-inflicted poisoning.MethodsConsecutive recruitment of patients aged 7–18, with normal IQ, admitted to poison control centre over 13 continuous months, with self-induced poisoning. All were assessed after guardians’ written informed consent for different risk factors identified for suicidal behavior using appropriate scales (PPS, SRRS-Y, FSSCS, BIS-11, J-TCI, Mini-Kid). Controls with no history of suicidal attempt were matched for age, sex and sociodemographics among their families.ResultsOne hundred and twenty cases (16.7 years ± 1.6 SD, 91% females) and 100 controls (age 16.4 years ± 1.7 SD, 90.8% females) were assessed. In cases, 90.8% were of low/middle socioeconomic status, 73.5% had previous attempt, average within 10 months, 17.5% planned their attempt, 10.8% had a witnessed attempt. Stressor within 2 days was reported in 75.9%, severe in 40%. Impulsivity was more in its cognitive, planning and motor components (P = 0.001 in each) among attempters. Cases scored more on Novelty seeking, harm avoidance and reward dependence than controls who had more persistence, self-directedness and cooperativeness. Attempters had significantly more past medical and psychiatric history (P = 0.001, 0.05 respectively), 77.5% had a working psychiatric illness, 2% in controls.ConclusionRepeated suicidal attempts were the majority, with impulsivity as a predictive risk, especially if psychiatric morbidity or ALE in youths were encountered.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
BACKGROUND In joint revision surgery, bone cement extraction remains a major challenge which even today has not seen a satisfactory solution yet. We studied in an experimental setting the impact of heat sources on the mechanical properties and microstructure of bone cement and determined the glass transition temperature (T G) of bone cement. As a result, it would be possible to establish a thermomechanical method which makes use of the structural and material-specific property changes inherent in bone cement at elevated temperatures. METHODS Prepared samples of polymerized bone cement were thermoanalyzed with a Netzsch STA 409 C thermal analyzer. Samples weighing approx. 55 mg were heated to 390 °C at a rate of 5 K/min. Both simultaneous differential thermal analysis and thermogravimetry were employed. The thermomechanically induced changes in the microstructure of the material were analyzed with a computed tomography scanner specifically developed for materials testing (3D-μXCT). RESULTS The bone cement changed from a firm elastic state over entropy-plastic (air atmosphere 60-155 °C) to a plastic viscosity state (air atmosphere >155 °C). Between 290 and 390 °C, the molten mass disintegrated (decomposition temperature). CONCLUSION Our study was able to determine the glass transition temperature (T G) of bone cement which was about 60 and 65 °C under air and nitrogen, respectively. Heating the dry bone cement up to at least 65 °C would be more than halve the strength needed to detach it. Bone cement extraction would then be easy and swift.

Abstract
We studied the value of carrying out urethral samples in women to diagnose gonorrhoea. All cases of genital gonorrhoea in women were identified (between 1 October 2000 and 30 September 2001) at the Whittall Street Clinic and the genitourinary medicine department at the Coventry and Warwickshire Hospital. Two hundred and twenty-four cases of female urethral gonorrhoea were identified. In 20 cases (6.3%) the urethra was the sole site of the infection. At the Whittall Street Clinic, we had to carry out 643 urethral samples in order to treat one additional case of gonorrhoea. On the other hand, 1204 urethral samples were requested to treat one additional case of female gonorrhoea at the Coventry and Warwickshire Hospital. In both units, use of the Gram-stained urethral smear permitted early treatment in only 1.8% of cases of genital gonorrhoea. Units with low prevalence of gonorrhoea should consider abandoning urethral samples for the diagnosis of gonorrhoea in women.

Abstract
INTRODUCTION Although well-established guidelines give advice on how to use analgesics, measure pain, and organize pain treatment, many patients still suffer from avoidable severe pain. We assume one reason for this is that pain is inadequately addressed in routine patient contacts. Thus, we aimed to evaluate the extent to which pain was addressed during patient contacts in routine orthopedic care. MATERIALS AND METHODS In a prospective observational study in an orthopedic unit of a university hospital, we invited physicians and nurses during their routine patient contacts to be observed by independent, trained monitors. The monitors systematically assessed all pain-related aspects, which were analyzed descriptively afterwards. RESULTS The monitors documented 572 physician-patient contacts with 7 physicians and 108 patients and 578 nurse-patient contacts with 12 nurses and 102 patients. Physicians and nurses asked their patients about pain in 20 and 16 % of the patient contacts, respectively. While in physician-patient contacts, patients most frequently addressed their current pain situation (in 35 % of contacts), in nurse-patient contacts, patients most frequently addressed their need for analgesics (52 %). Patients rated their pain intensity in 16 % of physician-patient contacts vs. 17 % of nurse-patient contacts. CONCLUSIONS Using a comprehensive external monitoring procedure, we found that systematic pain assessment was not optimally standardized and implemented for systematic, individualized pain therapy by physicians or nurses in our routine care setting.

Abstract
Epidermal cysts (atheroma) are the most common benign tumours of the skin with ubiquitous localisation all over the body. However, rupture of the atheroma and formation of an inclusion cyst with additional superinfections are frequently seen. Malignant transformations have rarely been reported. Presented here is the unusual case of a 65-year-old woman with multiple atheromas and a distinctive tumour of the upper limb. Imaging diagnostics showed malignant deformation. Contrary to the imaging findings the histological/microbiological examination showed an enormous superinfected and ruptured epidermoid cyst with multiple abscess formation in the ventral upper limb. Radical surgical restoration with salvage of the limb was frustrated because of honey-combed anterior soft tissue and the changing bacterial spectrum. After resection of the complete ventral compartment, remission was realised approximately. In the follow-up there was a recurring infection with spontaneous fistula formation that histologically impressed as a squamous cell carcinoma. After proximal ablation of the upper limb, total rehabilitation of the infection as well as the malignoma could be achieved.

Abstract
BACKGROUND Analysis of retinal vein amplitude in eyes of glaucoma patients. PATIENTS AND METHODS Motion of retinal veins was captured by Retinal Vessel Analyzer in duration of 30 seconds. Inferotemporal vein segments of 500 micrometers length in the immediate vicinity of, as well as away from the optic disc were chosen. Time behavior of the average segment diameter was analyzed by the self made software: dominating frequency (heart rate) was determined by Fourier analysis, and based on this an average pulse form was produced. Difference between the highest and lowest diameter point was the subject of analysis in 25 eyes of 25 glaucoma patients and 25 age-sex-matched healthy controls. RESULTS Pulse amplitude of retinal veins in healthy eyes was higher than in glaucoma patients: in the optic disc vicinity the pulse amplitude relative to baseline was 2.6 ± 2.1% in control eyes and 1.4 ± 0.8% in glaucoma eyes (t-test, p = 0.009). Away from the disc, it was 1.7 ± 1.0% and 1.1 ± 0.5% respectively (p = 0.01). CONCLUSIONS Retinal veins in glaucoma eyes demonstrate lower pulse amplitudes than healthy eyes, indicating disturbance in venous outflow and increased intraluminal venous pressure.

Abstract
Elimination of pathogens and emerging pollutants represents a key factor in integrated water resources management in arid regions. Within the SMART Jordan Valley project it is the objective of this study to assess the occurrence and examine the elimination of selected emerging pollutants and pathogens in waste water treatment and aquifer recharge. In batch and soil column studies non-chlorinated organophosphorous compounds (tri-n-butylphosphate, triphenylphosphate) and endocrine disruptors (e.g. 17-ß-estradiol, bisphenol A) proved to be biodegradable, while the X-ray contrast agents iomeprol and iopromide were eliminated in the soil columns only, and the chlorinated trialkylphosphates showed persistency. Treating waste water in a membrane bioreactor (MBR) in combination with powdered activated carbon (PAC) resulted in considerable removal rates also for the more persistent compounds such as the antiepileptic carbamazepine. Viruses were shown to be present in most of the Jordan Valley surface water samples. MBR treatment resulted in a decrease of MS2 bacteriophages used as model viruses.

Abstract
Pneumoparotitis is a rare cause of recurrent parotid swelling and its diagnosis can be challenging if the patient does not present with typical symptoms and is not in a risk group for parotitis. Several diagnostic techniques have been described in the literature including plain radiography, sialography and CT scanning. This report suggests that ultrasound is an efficient diagnostic aid and should be routinely used for the diagnosis of this condition.

Abstract
The pharmacokinetics of antiretroviral drugs in pregnancy is poorly understood. We reviewed the use of therapeutic drug monitoring (TDM) in clinical settings to document plasma concentrations of lopinavir during pregnancy and investigated how clinicians acted upon TDM results. A retrospective review was carried out of all HIV-infected pregnant women taking boosted lopinavir-based highly active antiretroviral therapy (HAART) at five National Health Service (NHS) centres in the UK between May 2004 and March 2007. Seventy-three women in receipt of lopinavir were identified, of whom 89% had plasma lopinavir concentrations above the suggested minimum recommended for wild-type HIV. Initial TDM results prompted dosage change in 10% and assessment of adherence and/or pharmacist review in 11%. TDM was repeated in 29%. TDM can play an important role in the clinical management of HIV-positive pregnant women, allowing informed dose modification and an alternative measure of adherence.

Abstract
This study is an initial step for the National Survey of Prevalence of Mental Disorders in Egypt. We conducted a door-to-door household survey of 14,640 adults aged 18-64 years in 5 regions in Egypt. Mental disorders were diagnosed using the MINI-Plus diagnostic interview. Overall prevalence was estimated at 16.93% of the studied adult population. The main problems were mood disorders, 6.43%, anxiety disorders, 4.75%, and multiple disorders, 4.72%. Mental disorders were associated with sociodemographic factors (e.g. being female, being unemployed, being divorced) and physical illness (e.g. heart disease, kidney disease, hypertension).

Abstract
4055 Background: SLN mapping (M) accurately stages many solid tumors including CRca. SLNs are 3–5 times more likely to have metastases (mets) when ultrastaged by microsections and IHC as compared to non-SLNs examined by standard pathological methods. It is unknown whether ultrastaging of initially -ve non-SLNs would lead to higher incidence of +ve nodes. Hence, we retrospectively analyzed all initially -ve non-SLNs by microsections and IHC similar to SLNs in CRca patients (pts) undergoing SLNM to determine its impact on final nodal staging. Methods: All CRca pts underwent SLNM by circumferential subserosal injection of 1% lymphazurin. First 1–4 blue nodes were marked as SLNs and ultrastaged by 4 section with H&E and 1 with IHC. All non-SLNs were initially examined by single H& E section and initial staging was made as per AJCC criteria. We re-examined all initially -ve non-SLNs similar to the SLNs by a senior pathologist blinded to prior results. Results: There were 156 pts with Cca and 44 pts with Rca. SLNM was successful in 100% pts with 94% accuracy rate. A total of 2,755 nodes (13.78/pt) were identified, of which 494 were SLNs and 2,261 were non-SLNs. Nodal positivity was 46% and 16% for Cca and Rca pts respectively. Mets were detected in 20.9% of SLNs vs. 8.6% of non-SLNs (p< 0.0001). The exclusive site of nodal mets was detected in 6.5% of SLNs vs.0.8% of non-SLNs (p< 0.0001). Skip mets were found in 6% of pts. After ultrastaging all initially -ve non-SLNs (n=2,065), only 0.58% (12/2065) nonSLNs became +ve in 12 pts. Of these, 10 pts already had +ve SLNs, hence no change of staging occurred. Only 2/200 pts (1%) with initially -ve non-SLNs were found to have a cluster of tumor cells. Thus, ultrastaging of 2065 initially -ve non-SLNs in 200 pts changed the staging from II to III only in 1% of pts. Conclusions: SLNM is highly accurate in staging CRca. The chance of finding additional mets by ultrastaging of all non-SLNs is extremely low (< 1%), hence of little benefit. Therefore, ultrastaging restricted to SLNs alone will assure accurate staging of CRca. [Table: see text] No significant financial relationships to disclose.
