HIV prevalence and associated risk factors among female sex workers in Dar es Salaam, Tanzania: tracking the epidemic.

Since 2014, HIV care and treatment services among key populations including female sex workers (FSWs) have intensified in Tanzania. We sought to track the epidemic among FSWs in Dar es Salaam, Tanzania. We conducted a cross-sectional integrated bio-behavioral survey using respondent-driven sampling and a structured questionnaire. Blood was drawn for HIV testing. Modified Poisson regression was used to determine factors associated with HIV infection. We recruited 958 FSWs (median age 26 years) of whom 952 consented to HIV testing. The HIV prevalence was 15.3% (95%CI: 12.5-18.6). Factors associated with higher HIV prevalence included old age (25-34 years: aPR 2.38; 95%CI: 1.23, 4.60 and over 35 years: aPR = 6.08; 95%CI: 3.19, 11.58) and having experienced sexual violence in the past year (aPR = 1.94; 95%CI: 1.34, 2.82). Attaining higher education level was associated with lower HIV prevalence (aPR = 0.51; 95%CI: 0.36, 0.73 for primary school level and aPR = 0.20; 95%CI: 0.08, 0.46 for secondary school level and/or above). The HIV prevalence among FSWs in Dar es Salaam has decreased by half since 2013. Prevention strategies should target older FSWs, aim to educate young girls, and institute approaches to mitigate violence among FSWs.

Patient satisfaction and oral health-related quality of life 10-15 years after orthodontic-surgical treatment of mandibular prognathism.

This study investigated 36 patients at 10-15 years after they had undergone mandibular setback surgery by intraoral vertical ramus osteotomy (IVRO) and subsequent intermaxillary fixation for 6 weeks. The patients completed a 37-item structured questionnaire to evaluate patient satisfaction and possible long-term effects of the treatment. Visual analogue scales were used to measure self-perceived changes in seven items concerning oral function and appearance. Oral health-related quality of life was assessed using the Oral Impacts on Daily Performance (OIDP) index. The main reasons for seeking treatment were to improve chewing function and appearance. The treatment had resulted in significant improvements regarding chewing function, appearance, bullying, and self-confidence in social settings (all P<0.05). All patients were either very satisfied (61%) or reasonably satisfied (39%) with the treatment result. The mean OIDP frequency score was 8.49 on a scale from 8 to 40. Seventy-four percent of the patients reported no oral impacts on quality of life. In conclusion, 10-15 years after combined orthodontic and IVRO surgical treatment of mandibular prognathism, the patients were satisfied, and oral health-related quality of life was reported to be good.

Skeletal and dental stability after intraoral vertical ramus osteotomy: a long-term follow-up.

The purpose of this study was to elucidate the long-term skeletal and dental stability after combined orthodontic and orthognathic surgical treatment of mandibular prognathism with the intraoral vertical ramus osteotomy (IVRO) as the surgical technique followed by 6 weeks of intermaxillary fixation (IMF). Thirty-six patients were included in the study. Mean age at surgery was 21.6 years. Lateral cephalograms and study casts obtained before the start of treatment (T0), and 8 weeks (T1), 1 year (T2), and 12.5 years (T3) after the operation were evaluated. Mean mandibular setback measured at point B was 8.3mm. Between T1 and T2, a mean anterior relapse of 12% of the setback was observed. Between T2 and T3, the anterior relapse persisted, but decreased to 7% of the setback measured at point B. Despite dental adjustments in both jaws, a statistically significant reduction in overjet was observed during both observation periods. However, the change of the mandible in an anterior direction was small and of minor clinical importance for most of the patients. In conclusion these results indicate that combined orthodontic and orthognathic surgical treatment of mandibular prognathism with the IVRO as the surgical procedure followed by 6 weeks of IMF provides predictable and good long-term clinical results.

White matter microstructure in chronic moderate-to-severe traumatic brain injury: Impact of acute-phase injury-related variables and associations with outcome measures.

This study examines how injury mechanisms and early neuroimaging and clinical measures impact white matter (WM) fractional anisotropy (FA), mean diffusivity (MD), and tract volumes in the chronic phase of traumatic brain injury (TBI) and how WM integrity in the chronic phase is associated with different outcome measures obtained at the same time. Diffusion tensor imaging (DTI) at 3 T was acquired more than 1 year after TBI in 49 moderate-to-severe-TBI survivors and 50 matched controls. DTI data were analyzed with tract-based spatial statistics and automated tractography. Moderate-to-severe TBI led to widespread FA decreases, MD increases, and tract volume reductions. In severe TBI and in acceleration/deceleration injuries, a specific FA loss was detected. A particular loss of FA was also present in the thalamus and the brainstem in all grades of diffuse axonal injury. Acute-phase Glasgow Coma Scale scores, number of microhemorrhages on T2*, lesion volume on fluid-attenuated inversion recovery, and duration of posttraumatic amnesia were associated with more widespread FA loss and MD increases in chronic TBI. Episodes of cerebral perfusion pressure <70 mmHg were specifically associated with reduced MD. Neither episodes of intracranial pressure >20 mmHg nor acute-phase Rotterdam CT scores were associated with WM changes. Glasgow Outcome Scale Extended scores and performance-based cognitive control functioning were associated with FA and MD changes, but self-reported cognitive control functioning was not. In conclusion, FA loss specifically reflects the primary injury severity and mechanism, whereas FA and MD changes are associated with objective measures of general and cognitive control functioning.

Intensive care and traumatic brain injury after the introduction of a treatment protocol: a prospective study.

BACKGROUND: Traumatic brain injury (TBI) treatment protocols have been introduced in the intensive care unit (ICU) to avoid secondary brain injury. In this study, we aimed to evaluate the deviations from such a treatment protocol and the frequency of extracranial complications, and relate these findings to outcome. METHODS: During a 5-year period (2004-2009), 133 patients with severe TBI [Glasgow Coma Scale (GCS) score ≤ 8] were prospectively included. The following deviations from treatment goals were studied: intracranial pressure (ICP), blood pressure, haemoglobin, blood glucose, serum sodium, serum albumin, body temperature and extracranial complications during the ICU stay. Outcome was assessed using Glasgow Outcome Scale Extended score at 12 months. RESULTS: The frequencies of deviations from the treatment goals were: episodes of intracranial hypertension 69.5% (of monitored patients), hypotension 20.3%, anaemia 77.4%, hyperglycaemia 42.9%, hyponatremia 34.6%, hypoalbuminemia 30.8% and hyperthermia 54.9%. Pulmonary complications were common (pneumonia 72.2%, acute respiratory distress syndrome/acute lung injury 31.6%). Thrombocytopenia (4.5%), severe sepsis (3.0%), renal failure (0.8%) and liver failure (0.8%) were infrequent. Twenty-six (19.5%) patients died within the first 12 months due to the head injury. Age, GCS score, pupil dilation, Injury Severity Score (ISS), ICP > 25 mmHg, hyperglycaemia and pneumonia predicted a worse outcome. CONCLUSIONS: Deviations from the TBI treatment protocol were frequent. Pneumonia was the most frequent extracranial complication. Age, GCS score, pupil dilation, ISS, high ICP, hyperglycaemia and pneumonia predicted a worse outcome.

Exocrine function in primary Sjögren syndrome: natural course and prognostic factors.

OBJECTIVES: Few studies have addressed the natural course of, or prognostic factors for the salivary and lacrimal function in primary Sjögren syndrome (SS). Except for the early stages, glandular function has been seemingly stable, and SS A antigen (SSA) seropositivity and hypocomplementemia may predict a decline in the van Bijsterveld score. The aim of the present study was to assess the natural course of the exocrine function in a larger cohort based on the American-European consensus criteria for SS, and to address possible predictive factors for a declining exocrine function. METHODS: We performed a retrospective cohort study. A total of 141 patients were investigated with the Schirmer I test and unstimulated whole saliva (UWS). Historical data regarding these tests and focus score were collected from the files of 111 patients. Median time from diagnosis to follow-up investigation was 5.0 years. RESULTS: Median UWS was unchanged during follow-up. Median Schirmer I test improved from 5.0 to 7.0 mm/5 min (p<0.05). Present Schirmer I test was associated with historical high IgG and IgA, positive SSA and SS B antigen (SSB) tests and high focus score, and present UWS with historical low C3/C4. Logistic regression identified high focus scores (odds ratio (OR) = 1.343), and low UWS (OR = 0.692) as factors predicting a 30% or more worsening of the Schirmer I test. High focus scores (OR = 1.488) predicted a 30% or more worsening of the UWS. CONCLUSION: We confirmed previous studies showing a stable or slightly improved exocrine function over time. High focus scores and low UWS were identified as independent predictors of a worsened exocrine function.

Synovial inflammation in active rheumatoid arthritis and psoriatic arthritis facilitates trapping of a variety of oral bacterial DNAs.

OBJECTIVE: To investigate the presence of oral bacterial DNAs in serum and synovial fluid (SF) of patients with active rheumatoid arthritis (RA) and psoriatic arthritis (PsA). METHODS: Serum and SF samples from 16 RA patients, 14 PsA patients, and 9 osteoarthritis (controls) patients were extracted for oral bacterial DNA. This was used in a checkerboard DNA-DNA-hybridization set up, to identify 40 different bacteria. RESULTS: Mean number +/- standard deviation (SD) of oral bacterial species in sera were 6.2 (3.2) in the RA group (p = 0.004) and 5.4 (2.7) in the PsA group (p = 0.009) compared to 2.1 (1.7) in the controls. Periodontitis associated species Porphyromonas gingivalis and Prevotella nigrescens were exclusively detected in RA and PsA. Mean number (+/- SD) of oral bacterial species in SF were 14.0 (6.8) in the RA (p = 0.001) and 19.4 (7.1) in the PsA group (p < 0.001) compared to 4.0 (1.7) in controls. P. gingivalis, Tannerella forsythensis and Prevotella intermedia were exclusively identified in RA and PsA SF. Higher means of DNAs were found in RA SF compared to RA serum (p < 0.001), and in PsA SF compared to PsA serum (p < 0.001). Higher concentrations of bacterial DNAs were found in RA and PsA compared to controls. CONCLUSION: Higher variety and concentrations of oral bacterial DNAs were found in SF compared to serum of RA and PsA patients. These findings indicate that synovial inflammation in RA and PsA may favor trapping of oral bacterial DNAs, suggesting a perpetuating effect of oral pathogens in joint disease.

Salivary gland and temporomandibular joint involvement in rheumatoid arthritis: relation to disease activity.

OBJECTIVES: To study temporomandibular joint (TMJ) involvement, salivary gland dysfunction and oral mucosal lesions in rheumatoid arthritis (RA), and to investigate the relationship to general disease activity. SUBJECTS AND METHODS: The TMJ dysfunction index (D(i)), mean salivary flow and disease activity score (DAS28), were calculated for 50 RA-patients, and 23 non-RA patients (controls). RESULTS: Median D(i) was 5.5 (range: 0-21) for the RA-patients compared with 2.0 (range: 0-9) for the controls (P < 0.0001). Pain on movement of the TMJ (P = 0.015), muscular pain (P = 0.006), TMJ pain (P = 0.019) and D(i) as a total (P = 0.009), significantly correlated with DAS28. Mean resting whole saliva (RWS) flow was 2.6 (s.d. 2.4) ml per 15 min for the RA-patients and 4.5 (s.d. 3.0) for the controls (P = 0.003). RWS correlated positively with haemoglobin (P = 0.021) and negatively with Westergren erythrocyte sedimentation rate (ESR) (P = 0.029). No major differences in frequency of oral mucosal lesions were seen between RA-patients and controls. CONCLUSIONS: Higher frequency of TMJ and salivary gland dysfunction in RA-patients compared with controls has been demonstrated. RA disease activity is associated with hyposalivation and TMJ dysfunction.

[Polycystic lipomembranous osteodysplasia with sclerosing leukoencephalopathy]. / Polycystisk lipomembranøs osteodysplasi med skleroserende leukoencefalopati.

BACKGROUND: Polycystic lipomembranous osteodysplasia with sclerosing leukoencephalopathy (Nasu-Hakola syndrome) (PLO-SL) is an unusual cause of early dementia in which the decline in cognitive function is associated with multiple bone cysts, in particular in hands and feet. About 165 cases of this autosomal recessive hereditary disease have been reported worldwide, mostly from Finland and Japan. MATERIAL AND METHODS: In this article, case histories of PLO-SL are presented of two brothers who were born to consanguineous parents on an island outside the western coast of Norway. They are the 3rd and 4th patients in Norway described with this disorder. RESULTS: One of the brothers was diagnosed retrospectively and the diagnosis was not made in the other even when he had fractures without entirely adequate trauma. INTERPRETATION: It is suspected that the disease is underdiagnosed. For this reason, all patients with polycystic lesions in the skeleton should be evaluated for their mental state and all patients with an etiologically unclear dementia before the age of 50 should be investigated with x-rays of hands and/or feet.

Prenatal karyotyping of choroid plexus cysts.

OBJECTIVES: A retrospective, descriptive study of 50 cases with choroid plexus cysts diagnosed by ultrasonography. METHODS: All case charts were studied and additional information was collected regarding children born outside Uppsala. RESULTS: All 50 cases were offered a test for chromosome aberrations, 46 accepted and were tested by chorion villi sampling or amniocentesis. In ten cases additional malformations were found, including one trisomy 13 and one trisomy 18. No relationship was found between the diameter, bilaterality or the complexity of the cyst. CONCLUSIONS: Fetus with choroid plexus cysts should be examined carefully by ultrasonography. Since the complication risk of invasive diagnostic procedures is very small these patients may be offered a test for chromosomal aberrations.

Fracture of the proximal tibia after anterior cruciate ligament reconstruction: a case report.

A case of fracture of the proximal tibia at the site of graft harvest for an anterior cruciate ligament reconstruction is reported. This fracture, at the distal edge of the harvest site on the tibial tubercle, was the result of stress concentration at this location. The patient's tibia fracture was treated with a long leg cast and healed without complication. Fracture of the patella at the graft harvest site has been reported as a complication of anterior cruciate ligament reconstruction. This is the first report of a fracture of the tibia at the site of graft harvest.

Are you ready?

A discharge planning group designed and facilitated by occupational therapy staff in an acute psychiatric treatment setting is described. The purpose of the group is to involve patients in their plans for leaving the hospital and to smooth their transition to the settings to which they are going. Other members of the team, nurses, social workers, as well as psychiatrists, are involved in implementing this program. In this presentation, the procedures used in the group are described, case examples of two patients are discussed, and suggestions for generalizing this model of group process to other settings are made.

[On the relationship between migration and unemployment]. / Om sammenhengen mellom flytting og arbeidsloshet

PIP: The relationship between internal migration and labor market trends is analyzed for Norwegian counties and labor exchange districts. The main motives for migration and the major reasons for unemployment are discussed. The expected negative correlation between high unemployment and low or negative net migration occurs, but it is stronger at the county than at the labor exchange level. When change in unemployment between 1974 and 1978 is compared with change in net migration there is no clear correlation.^ieng
