The psychosocial impact of war trauma and torture on Southeast Asian refugees

More than 700,000 refugees from Southeast Asia have settled in the United States since 1975. Although many have suffered serious trauma, including torture, few clinical reports have described their trauma-related symptoms and psychosocial problems. The authors conducted a treatment study of 52 patients in a clinic for Indochinese. They found that these patients were a highly traumatized group; each had experienced a mean of 10 traumatic events and two torture experiences. Many of the patients had concurrent diagnoses of major affective disorder and posttraumatic stress disorder as well as medical and social disabilities associated with their history of trauma. The authors also found that Cambodian women without spouses demonstrated more serious psychiatric and social impairments than all other Indochinese patient groups.     

Surgical treatment of cystic swellings of the scrotum under local anaesthesia.

Fifty-one patients underwent surgery for symptomatic epididymal cysts or hydroceles, using local anaesthesia with no sedation and no diathermy. Of the patients surveyed, 91% found the procedure comfortable or uncomfortable, 9% finding it painful. Most patients (89%) were fully recovered after 3 weeks. None of the patients had to have operative intervention for complications. Treatment of these conditions under local anaesthesia is cost-effective, and can be performed with the minimum of special equipment on patients who might otherwise be unfit for a general anaesthetic.     

Longitudinal in vivo effects of growth hormone overexpression on bone in transgenic mice.

In this study we examined the effect of systemic overexpression of GH on bone in transgenic mice longitudinally in vivo over a period of 9 months. We observed substantially increased BMC in GH transgenic mice and a significant reduction in serum osteocalcin. GH effects on bone were strongly dependent on gender and developmental stage. INTRODUCTION: State-of-the-art bone marker and microimaging technology was applied in this longitudinal study to examine bone metabolism, BMC, bone density, and cortical bone structure over the life span of growth hormone (GH) transgenic (tg) mice. MATERIALS AND METHODS: Thirty-eight mice from four genetic groups (male, female, tg, and controls) were examined with DXA, and their femur and tibia were examined with peripheral QCT (pQCT). Osteocalcin (formation) and collagen cross-links (resorption) from serum and urine were also measured at postnatal weeks 3, 6, 9, 12, 18, 26, and 38. RESULTS: GH tg mice displayed a significant increase in body weight (up to 50%) and BMC (up to 90%), but serum osteocalcin was significantly reduced compared with controls. GH tg females (but not males) displayed increased trabecular density over controls up to week 12. In contrast, male (but not female) GH tg mice displayed a higher cortical cross-sectional area than controls. Cortical density was significantly lower in both male and female GH tg mice compared with control mice. CONCLUSIONS: The increase in BMC in GH tg mice is associated with reduced serum osteocalcin levels, indicating that bone turnover may be lower than in the control mice. On a structural level, bone responds to GH excess in a gender-specific manner, with alterations varying substantially between different developmental stages.     

The epidemiology of psychosis: the Suffolk County Mental Health Project.

This article describes the rationale, aims, and methodology of an epidemiological study of psychosis being conducted in Suffolk County, New York. A sample of first-admission patients is drawn from 10 inpatient and 25 outpatient facilities. Diagnostic psychosocial interviews are conducted shortly after admission to treatment, and at 6- and 24-month followup. Consensus diagnoses are made after each interview. Demographic and clinical background characteristics of the first 250 subjects enrolled over a 2-year period are presented here. The response rate was 76 percent. Based on the initial interview, 75 percent of subjects received a diagnosis involving psychosis. The three most common diagnoses were schizophrenia, bipolar disorder with psychotic features, and major depression with psychotic features. Among subjects with psychosis, 58 percent of males and 29 percent of females had a history of substance abuse/dependence. Gender differences were found on several background and clinical characteristics. Males were somewhat younger, less likely to have ever married, and had less education. Although the median length of hospitalization was the same for females and males (27 days), females were more likely to be hospitalized within 1 month of the occurrence of their first psychotic symptom (60% of females compared to 37% of males). Subjects with schizophrenia-related disorders were significantly more impaired on an assessment of negative symptoms than were affectively ill subjects, but clinical ratings of depression were not significantly different across diagnostic groups.     

Anatomic subdivisions in human temporal cortical neuronal activity related to recent verbal memory.

We identified functional anatomical subdivisions of human lateral and basal temporal cortex related to recent verbal memory for object names, text and auditory words. Extracellular neuronal activity was recorded during memory encoding compared to identification, during encoding, storage or recall retrieval stages of the memory task, during recognition memory, and during implicit memory as measured by repetition priming. Changes in frequency of activity during encoding were recorded from most neurons. In lateral temporal cortex, these encoding changes in the dominant hemisphere were more likely to be polymodal, whereas those in nondominant hemisphere were unimodal. There was substantial separation of neurons with changes in other aspects of memory, defining additional subdivisions. Inferior lateral and basal cortex were related to memory stages, and superior-posterior lateral cortex was related to implicit and recognition memory.     

Cell-mediated immune responses to chlamydial antigens in guinea pigs injected with inactivated chlamydiae

Cell-mediated immunity (CMI) to chlamydial antigens was readily induced in guinea pigs by a single injection of Betaprone-inactivated chlamydiae in complete Freund adjuvant. The CMI was measured in vivo by delayed hypersensitivity skin tests, and in vitro by inhibition of migration of peritoneal exudate cells and by proliferation of lymph node lymphocytes. There was an overall correlation between in vivo and in vitro responses. Of the in vitro assays, migration inhibition reflected the state of sensitization, as judged by skin tests, more uniformly than lymphocyte stimulation. Extensive inter- and intra-species cross-reactivity was noted between LB-1, a strain ofC. trachomatis, and three strains ofC. psittaci, 6BC, GPIC, and 562F. Cross-reactivity between LB-1 and 6BC was one-way only, by all three parameters: LB-1 elicited strong cross-reactions in 6BC-immunized animals but not vice versa. Antichlamydial antibodies could not be demonstrated in any of the animals by microimmunofluorescence.     

Increased COVID-19 Lockdown Burden in Italian Adults with Gastrointestinal Diseases

Background: Coronavirus disease 2019 (COVID-19) causes not only severe illness but also detrimental effects associated with the lockdown measures. The present study aimed to evaluate reported lifestyle changes in a cohort of adults in Italy, including physical exercise, food choices, and psychological wellbeing, after two months of lockdown. Methods: A web survey on social media (Facebook and LinkedIn) of 32 multiple-choice questions aiming to evaluate the impact of the national COVID-19 lockdown in a sample of Italian adults. Results: We received 1378 complete responses (women 68.3%, mean age 39.5 ± 12.5 years). The percentage of participants reporting regular exercise decreased during lockdown (52 vs. 56.5%). The vast majority of people continued to consume the three traditional meals per day, but the consumption of meat, fish, and eggs significantly decreased. Women reported more frequent anxiety, sadness, fear, and feelings of insecurity than men. The factors predicting the worst outcome during the lockdown were being a woman, low education and income, gastrointestinal diseases. Conclusion: The lockdown has had a limited impact on food choices and physical exercise in Italian adults of our series, since most of them made an effort to improve their lifestyle. However, women with gastrointestinal diseases reported more frequent negative feelings and poor adaptation to the lockdown.     

COVID-19 in pediatric kidney transplantation: The Improving Renal Outcomes Collaborative

There are limited data on the impact of COVID-19 in children with a kidney transplant (KT). We conducted a prospective cohort study through the Improving Renal Outcomes Collaborative (IROC) to collect clinical outcome data about COVID-19 in pediatric KT patients. Twenty-two IROC centers that care for 2732 patients submitted testing and outcomes data for 281 patients tested for SARS-CoV-2 by PCR. Testing indications included symptoms and/or potential exposures to COVID-19 (N = 134, 47.7%) and/or testing per hospital policy (N = 154, 54.8%). Overall, 24 (8.5%) patients tested positive, of which 15 (63%) were symptomatic. Of the COVID-19-positive patients, 16 were managed as outpatients, six received non-ICU inpatient care and two were admitted to the ICU. There were no episodes of respiratory failure, allograft loss, or death associated with COVID-19. To estimate incidence, subanalysis was performed for 13 centers that care for 1686 patients that submitted all negative and positive COVID-19 results. Of the 229 tested patients at these 13 centers, 10 (5 asymptomatic) patients tested positive, yielding an overall incidence of 0.6% and an incidence among tested patients of 4.4%. Pediatric KT patients in the United States had a low estimated incidence of COVID-19 disease and excellent short-term outcomes.
